and Section 12, in the case of all other Revolving Credit Loans, have been

the immediately preceding calendar quarter commencing on the first such date
following the date hereof, with a final payment on the Revolving Credit Loan

     2.3. REDUCTION OF TOTAL COMMITMENT. The Borrower shall have the right at
any time and from time to time upon five (5) Business Days prior written notice
to the Administrative Agent to reduce by $5,000,000 or an integral multiple of

whereupon the Commitments of the Lenders shall be reduced PRO RATA in accordance

Commitment or, if less, the outstanding amount of all Revolving Credit Loans
made by such Lender, plus interest accrued thereon, as set forth below. The
Borrower irrevocably authorizes each Lender to make or cause to be made, at or
about the time of the Drawdown Date of any Revolving Credit Loan or at the time
of receipt of any payment of principal on such Lender's Revolving Credit Note,
an appropriate notation on such Lender's Record reflecting the making of such
Revolving Credit Loan or (as the case may be) the receipt of such payment. The
outstanding amount of the Revolving Credit Loans set forth on such Lender's
Record shall be PRIMA FACIE evidence of the principal amount thereof owing and
unpaid to such Lender, but the failure to record, or any error in so recording,
any such amount on such Lender's Record shall not limit or otherwise affect the
obligations of the Borrower hereunder or under any Revolving Credit Note to make
payments of principal of or interest on any Revolving Credit Note when due.

     2.5. INTEREST ON REVOLVING CREDIT LOANS. Except as otherwise provided in
Section 5.11,

            (b)     Each Revolving Credit Loan which is a Eurodollar Rate Loan
     shall bear interest for the period commencing with the Drawdown Date
     thereof and ending on the last day of the Interest Period with respect
     thereto at the rate per annum equal to the Eurodollar Rate determined for
     such Interest Period PLUS the Applicable Margin with respect to Eurodollar
     Rate Loans as in effect from time to time.

The Borrower promises to pay interest on each Revolving Credit Loan in arrears
on each Interest Payment Date with respect thereto.

     Borrower may elect from time to time to convert any outstanding Revolving
     Credit Loan to a Revolving Credit Loan of another Type, PROVIDED that (a)
     with respect to any such conversion of a Eurodollar Rate Loan to a Base
     Rate Loan, the Borrower shall give the Administrative Agent at least one
     (1) Business Days prior written notice of such election; (b) with respect
     to any such conversion of a Base Rate Loan to a Eurodollar Rate Loan, the
     Borrower shall give the Administrative Agent at least three (3) Eurodollar
     Business Days prior written notice of such election; (c) with respect to
     any such conversion of a Eurodollar Rate Loan into a Base Rate Loan, such
     conversion shall only be made on the last day of the Interest Period with
     respect thereto and (d) no Revolving Credit Loan may be converted into a
     Eurodollar Rate Loan when any Default or Event of Default has occurred and
     is continuing. On the date on which such conversion is being made each
     Lender shall take such action as is necessary to transfer its Commitment
     Percentage of such Revolving Credit Loans to its Domestic Lending Office or
     its Eurodollar Lending Office, as the case may be. All or any part of
     outstanding Revolving Credit Loans of any Type may be converted into a
     Revolving Credit Loan of another Type as provided herein, PROVIDED that any
     partial conversion shall be in an aggregate principal amount of $500,000 or
     a whole multiple of $250,000 in excess thereof. Each Conversion Request
     relating to the conversion of a Revolving Credit Loan to a Eurodollar Rate
     Loan shall be irrevocable by the Borrower.

            2.7.2. CONTINUATION OF TYPE OF REVOLVING CREDIT LOAN. Any Revolving
     Credit Loan of any Type may be continued as a Revolving Credit Loan of the
     same Type upon the expiration of an Interest Period with respect thereto by
     compliance by the Borrower with the notice provisions contained in Section
     2.7.1; PROVIDED that no Eurodollar Rate Loan may be continued as such when
     any Default or Event of Default has occurred and is continuing, but shall
     be automatically converted to a Base Rate Loan on the last day of the first
     Interest Period relating thereto ending during the continuance of any
     Default or Event of Default of which officers of the Administrative Agent
     active upon the Borrower's account have actual knowledge. In the event that
     the Borrower fails to provide any such notice with respect to the
     continuation of any Eurodollar Rate Loan as such, then such Eurodollar Rate
     Loan shall be automatically converted to a Base Rate Loan on the last day
     of the first Interest Period relating thereto. The Administrative Agent
     shall notify the Lenders promptly when any such automatic conversion
     contemplated by this Section 2.7 is scheduled to occur.

            2.7.3. EURODOLLAR RATE LOANS. Any conversion to or from Eurodollar
     Rate Loans shall be in such amounts and be made pursuant to such elections

     Eurodollar Rate Loans having the same Interest Period shall not be less
     than $500,000 or a whole multiple of $250,000 in excess thereof. No more
     than four (4) Eurodollar Rate Loans having different Interest Periods may
     be outstanding at any time.

     Revolving Credit Loans. Upon receipt from each Lender of such amount, and
     upon receipt of the documents required by Sections 11 (only in the case of
     the initial Revolving Credit Loans) and 12 (in the case of any Revolving
     Credit Loan) and the satisfaction of the other conditions set forth
     therein, to the extent applicable, the Administrative Agent will make
     available to the Borrower the aggregate amount of such Revolving Credit
     Loans made available to the Administrative Agent by the Lenders. The
     failure or refusal of any Lender to make available to the Administrative
     Agent at the aforesaid time and place on any Drawdown Date the amount of
     its Commitment Percentage of the requested Revolving Credit Loans shall not
     relieve any other Lender from its several obligation hereunder to make
     available to the Administrative Agent the amount of such other Lender's
     Commitment Percentage of any requested Revolving Credit Loans.

            2.8.2. ADVANCES BY ADMINISTRATIVE AGENT. The Administrative Agent
     may, unless notified to the contrary by any Lender prior to a Drawdown
     Date, assume that such Lender has made available to the Administrative
     Agent on such Drawdown Date the amount of such Lender's Commitment
     Percentage of the Revolving Credit Loans to be made on such Drawdown Date,
     and the Administrative Agent may (but it shall not be required to), in
     reliance upon such assumption, make available to the Borrower a
     corresponding amount. If any Lender makes available to the Administrative
     Agent such amount on a date after such Drawdown Date, such Lender shall pay
     to the Administrative Agent on demand an amount equal to the product of (a)
     the average computed for the period referred to in clause (c) below, of the
     weighted average interest rate paid by the Administrative Agent for federal
     funds acquired by the Administrative Agent during each day included in such
     period, TIMES (b) the amount of such Lender's Commitment Percentage of such
     Revolving Credit Loans, TIMES (c) a fraction, the numerator of which is the
     number of days that elapse from and including such Drawdown Date to the
     date on which the amount of such Lender's Commitment Percentage of such
     Revolving Credit Loans shall become immediately available to the
     Administrative Agent, and the denominator of which is 360. A statement of
     the Administrative Agent submitted to such Lender with respect to any
     amounts owing under this paragraph shall be PRIMA FACIE evidence of the
     amount due and owing to the Administrative Agent by such Lender. If the
     amount of such Lender's Commitment Percentage of such

<Page>

                                      -23-

     Revolving Credit Loans is not made available to the Administrative Agent by
     such Lender within three (3) Business Days following such Drawdown Date,
     the Administrative Agent shall be entitled to recover such amount from the
     Borrower on demand, with interest thereon at the rate per annum applicable
     to the Revolving Credit Loans made on such Drawdown Date.

                   3. REPAYMENT OF THE REVOLVING CREDIT LOANS.

     3.1. MATURITY. The Borrower promises to pay on the Revolving Credit Loan
Maturity Date, and there shall become absolutely due and payable on the
Revolving Credit Loan Maturity Date, all of the Revolving Credit Loans
outstanding on such date, together with any and all accrued and unpaid interest
thereon.

     3.2.  MANDATORY REPAYMENTS.

            3.2.1. GENERAL. If at any time the sum of the outstanding amount of
     the Revolving Credit Loans, the Maximum Drawing Amount and all Unpaid
     Reimbursement Obligations exceeds the Total Commitment at such time, then
     the Borrower shall immediately pay the amount of such excess to the
     Administrative Agent for the respective accounts of the Lenders for
     application: first, to any Unpaid Reimbursement Obligations; second, to the
     Revolving Credit Loans; and third, to provide to the Administrative Agent
     cash collateral for Reimbursement Obligations as contemplated by Section
     4.2(b) and (c). Each payment of any Unpaid Reimbursement Obligations or
     prepayment of Revolving Credit Loans shall be allocated among the Lenders,
     in proportion, as nearly as practicable, to each Reimbursement Obligation
     or (as the case may be) the respective unpaid principal amount of each
     Lender's Revolving Credit Note, with adjustments to the extent practicable
     to equalize any prior payments or repayments not exactly in proportion.

            3.2.2. PROCEEDS OF CERTAIN EVENTS. Concurrently with the receipt by
     the Borrower or any Subsidiary of Net Cash Equity Issuance Proceeds of the
     Borrower or any of its Subsidiaries, the Borrower shall pay to the
     Administrative Agent for the respective accounts of the Lenders an amount
     equal to one hundred percent (100%) of such proceeds, to be applied to
     reduce the outstanding amount of the Revolving Credit Loans (and, for the
     avoidance of doubt, will not require any mandatory reduction in the Total
     Commitment), PROVIDED, HOWEVER, notwithstanding the foregoing, to the
     extent the Borrower or any Subsidiary receives any Net Cash Equity Issuance
     Proceeds directly from the sale of a Subsidiary which is expressly
     permitted by the terms of this Credit Agreement, the Borrower shall not be
     required to pay such proceeds to the Lenders so long as no Default or Event
     of Default has occurred and is continuing both immediately prior to, and
     immediately after, receiving such Net Cash Equity Issuance Proceeds. Such
     mandatory prepayments shall be allocated among the Lenders in proportion,
     as nearly as practicable, to the respective outstanding amounts of each
     Lender's Revolving Credit Note, with adjustments

<Page>

                                      -24-

     to the extent practicable to equalize any prior prepayments not exactly in
     proportion.

     3.3. OPTIONAL REPAYMENTS OF REVOLVING CREDIT LOANS. The Borrower shall have
the right, at its election, to repay the outstanding amount of the Revolving
Credit Loans, as a whole or in part, at any time without penalty or premium,
PROVIDED that any full or partial prepayment of the outstanding amount of any
Eurodollar Rate Loans pursuant to this Section 3.3 which is made on any date
other than the last day of the Interest Period relating thereto shall be subject
to Section 5.10 hereof. The Borrower shall give the Administrative Agent, no
later than 10:00 a.m., Boston time, at least one (1) Business Days prior written
notice of any proposed prepayment pursuant to this Section 3.3 of Base Rate
Loans, and three (3) Eurodollar Business Days notice of any proposed prepayment
pursuant to this Section 3.3 of Eurodollar Rate Loans, in each case specifying
the proposed date of prepayment of Revolving Credit Loans and the principal
amount to be prepaid. Each such partial prepayment of the Revolving Credit Loans
shall be in an integral multiple of $500,000, shall be accompanied by the
payment of accrued interest on the principal prepaid to the date of prepayment
and shall be applied, in the absence of instruction by the Borrower, first to
the principal of Base Rate Loans and then to the principal of Eurodollar Rate
Loans. Each partial prepayment shall be allocated among the Lenders, in
proportion, as nearly as practicable, to the respective unpaid principal amount
of each Lender's Revolving Credit Note, with adjustments to the extent
practicable to equalize any prior repayments not exactly in proportion.

                              4. LETTERS OF CREDIT.

     4.1. LETTER OF CREDIT COMMITMENTS.

            4.1.1. COMMITMENT TO ISSUE LETTERS OF CREDIT. Subject to the terms
     and conditions hereof and the execution and delivery by the Borrower of a
     letter of credit application on the Administrative Agent's customary form
     (a "LETTER OF CREDIT APPLICATION"), the Administrative Agent on behalf of
     the Lenders and in reliance upon the agreement of the Lenders set forth in
     Section 4.1.4 and upon the representations and warranties of the Borrower
     contained herein, agrees, in its individual capacity, to issue, extend and
     renew for the account of the Borrower one or more standby or documentary
     letters of credit (individually, a "LETTER OF CREDIT"), in such form as may
     be requested from time to time by the Borrower and agreed to by the
     Administrative Agent and in such currency other than Dollars as the
     Borrower may request and which is approved in writing by all of the
     Lenders; PROVIDED, HOWEVER, that, after giving effect to such request, (a)
     the sum of the aggregate Maximum Drawing Amount and all Unpaid
     Reimbursement Obligations shall not exceed the Dollar equivalent of
     $15,000,000 at any one time and (b) the sum of (i) the Maximum Drawing
     Amount on all Letters of Credit, (ii) all Unpaid Reimbursement Obligations,
     and (iii) the amount of all Revolving Credit Loans outstanding shall not
     exceed the Total Commitment at such time.

<Page>

                                      -25-

            4.1.2. LETTER OF CREDIT APPLICATIONS. Each Letter of Credit
     Application shall be completed to the satisfaction of the Administrative
     Agent. In the event that any provision of any Letter of Credit Application
     shall be inconsistent with any provision of this Credit Agreement, then the
     provisions of this Credit Agreement shall, to the extent of any such
     inconsistency, govern.

            4.1.3. TERMS OF LETTERS OF CREDIT. Each Letter of Credit issued,
     extended or renewed hereunder shall, among other things, (a) provide for
     the payment of sight drafts for honor thereunder when presented in
     accordance with the terms thereof and when accompanied by the documents
     described therein, and (b) have an expiry date no later than the date which
     is fourteen (14) days (or, if the Letter of Credit is confirmed by a
     confirmer or otherwise provides for one or more nominated persons,
     forty-five (45) days) prior to the Revolving Credit Loan Maturity Date.
     Each Letter of Credit so issued, extended or renewed shall be subject to
     the Uniform Customs and Practice for Documentary Credits (1993 Revision),
     International Chamber of Commerce Publication No. 500 or any successor
     version thereto adopted by the Administrative Agent in the ordinary course
     of its business as a letter of credit issuer and in effect at the time of
     issuance of such Letter of Credit (the "UNIFORM CUSTOMS") or, in the case
     of a standby Letter of Credit, either the Uniform Customs or the
     International Standby Practices (ISP98), International Chamber of Commerce
     Publication No. 590, or any successor code of standby letter of credit
     practices among banks adopted by the Administrative Agent in the ordinary
     course of its business as a standby letter of credit issuer and in effect
     at the time of issuance of such Letter of Credit.

            4.1.4. REIMBURSEMENT OBLIGATIONS OF LENDERS. Each Lender severally
     agrees that it shall be absolutely liable, without regard to the occurrence
     of any Default or Event of Default or any other condition precedent
     whatsoever, to the extent of such Lender's Commitment Percentage, to
     reimburse the Administrative Agent on demand for the amount of each draft
     paid by the Administrative Agent under each Letter of Credit to the extent
     that such amount is not reimbursed by the Borrower pursuant to Section 4.2
     (such agreement for a Lender being called herein the "LETTER OF CREDIT
     PARTICIPATION" of such Lender).

            4.1.5. PARTICIPATIONS OF LENDERS. Each such payment made by a Lender
     shall be treated as the purchase by such Lender of a participating interest
     in the Borrower's Reimbursement Obligation under Section 4.2 in an amount
     equal to such payment. Each Lender shall share in accordance with its
     participating interest in any interest which accrues pursuant to Section
     4.2.

     4.2. REIMBURSEMENT OBLIGATION OF THE BORROWER. In order to induce the
Administrative Agent to issue, extend and renew each Letter of Credit and the
Lenders to participate therein, the Borrower hereby agrees to reimburse or pay
to the Administrative Agent, for the account of the Administrative Agent or (as
the case may be) the Lenders, with respect to each Letter of Credit issued,
extended or renewed by the Administrative Agent hereunder,

<Page>

                                      -26-

            (a)     except as otherwise expressly provided in Section 4.2(b) and
     (c), on each date that any draft presented under such Letter of Credit is
     honored by the Administrative Agent, or the Administrative Agent otherwise
     makes a payment with respect thereto, (i) the amount paid by the
     Administrative Agent under or with respect to such Letter of Credit, and
     (ii) the amount of any taxes, fees, charges or other costs and expenses
     whatsoever incurred by the Administrative Agent or any Lender in connection
     with any payment made by the Administrative Agent or any Lender under, or
     with respect to, such Letter of Credit,

            (b)     upon the reduction (but not termination) of the Total
     Commitment to an amount less than the Maximum Drawing Amount, an amount
     equal to such difference, which amount shall be held by the Administrative
     Agent for the benefit of the Lenders and the Administrative Agent as cash
     collateral for all Reimbursement Obligations, and

            (c)     upon the termination of the Total Commitment, or the
     acceleration of the Reimbursement Obligations with respect to all Letters
     of Credit in accordance with Section 13, an amount equal to the then
     Maximum Drawing Amount on all Letters of Credit, which amount shall be held
     by the Administrative Agent for the benefit of the Lenders and the
     Administrative Agent as cash collateral for all Reimbursement Obligations.

Each such payment shall be made to the Administrative Agent at the
Administrative Agent's Office in immediately available funds. Interest on any
and all amounts remaining unpaid by the Borrower under this Section 4.2 at any
time from the date such amounts become due and payable (whether as stated in
this Section 4.2, by acceleration or otherwise) until payment in full (whether
before or after judgment) shall be payable to the Administrative Agent on demand
at the rate specified in Section 5.11 for overdue principal on the Revolving
Credit Loans.

     4.3. LETTER OF CREDIT PAYMENTS. If any draft shall be presented or other
demand for payment shall be made under any Letter of Credit, the Administrative
Agent shall notify the Borrower of the date and amount of the draft presented or
demand for payment and of the date and time when it expects to pay such draft or
honor such demand for payment. If the Borrower fails to reimburse the
Administrative Agent as provided in Section 4.2 on or before the date that such
draft is paid or other payment is made by the Administrative Agent, the
Administrative Agent may at any time thereafter notify the Lenders of the amount
of any such Unpaid Reimbursement Obligation. No later than 3:00 p.m. (Boston
time) on the Business Day next following the receipt of such notice, each Lender
shall make available to the Administrative Agent, at the Administrative Agent's
Office, in immediately available funds, such Lender's Commitment Percentage of
such Unpaid Reimbursement Obligation, together with an amount equal to the
product of (a) the average, computed for the period referred to in clause (c)
below, of the weighted average interest rate paid by the Administrative Agent
for federal funds acquired by the Administrative Agent during each day included
in such period, TIMES (b) the amount equal to such Lender's Commitment
Percentage of

<Page>

                                      -27-

such Unpaid Reimbursement Obligation, TIMES (c) a fraction, the numerator of
which is the number of days that elapse from and including the date the
Administrative Agent paid the draft presented for honor or otherwise made
payment to the date on which such Lender's Commitment Percentage of such Unpaid
Reimbursement Obligation shall become immediately available to the
Administrative Agent, and the denominator of which is 360. The responsibility of
the Administrative Agent to the Borrower and the Lenders shall be only to
determine that the documents (including each draft) delivered under each Letter
of Credit in connection with such presentment shall be in conformity in all
material respects with such Letter of Credit.

     4.4. OBLIGATIONS ABSOLUTE. The Borrower's obligations under this Section 4
shall be absolute and unconditional under any and all circumstances and
irrespective of the occurrence of any Default or Event of Default or any
condition precedent whatsoever or any setoff, counterclaim or defense to payment
which the Borrower may have or have had against the Administrative Agent, any
Lender or any beneficiary of a Letter of Credit. The Borrower further agrees
with the Administrative Agent and the Lenders that the Administrative Agent and
the Lenders shall not be responsible for, and the Borrower's Reimbursement
Obligations under Section 4.2 shall not be affected by, among other things, the
validity or genuineness of documents or of any endorsements thereon, even if
such documents should in fact prove to be in any or all respects invalid,
fraudulent or forged, or any dispute between or among the Borrower, the
beneficiary of any Letter of Credit or any financing institution or other party
to which any Letter of Credit may be transferred or any claims or defenses
whatsoever of the Borrower against the beneficiary of any Letter of Credit or
any such transferee. The Administrative Agent and the Lenders shall not be
liable for any error, omission, interruption or delay in transmission, dispatch
or delivery of any message or advice, however transmitted, in connection with
any Letter of Credit. The Borrower agrees that any action taken or omitted by
the Administrative Agent or any Lender under or in connection with each Letter
of Credit and the related drafts and documents, if done in good faith, shall be
binding upon the Borrower and shall not result in any liability on the part of
the Administrative Agent or any Lender to the Borrower. Nothing contained in
this Section 4.4 shall in any manner limit or otherwise affect any claims the
Borrower may have against the Administrative Agent arising from the gross
negligence or willful misconduct of the Administrative Agent as the issuer of
any Letter of Credit.

     4.5. RELIANCE BY ISSUER. To the extent not inconsistent with Section 4.4,
the Administrative Agent shall be entitled to rely, and shall be fully protected
in relying upon, any Letter of Credit, draft, writing, resolution, notice,
consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or
teletype message, statement, order or other document believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person
or Persons and upon advice and statements of legal counsel, independent
accountants and other experts selected by the Administrative Agent.

     4.6. LETTER OF CREDIT FEE. The Borrower shall pay a fee (in each case, a
"LETTER OF CREDIT FEE") to the Administrative Agent in respect of each Letter of
Credit in an amount

<Page>

                                      -28-

equal to the Applicable Margin per annum with respect to Letter of Credit Fees
of the face amount of such Letter of Credit plus an amount equal to one eighth
of one percent (1/8%) per annum of the face amount of such Letter of Credit
which shall be for the account of the Administrative Agent, as a fronting fee,
and the balance of which Letter of Credit Fee shall be for the accounts of the
Lenders in accordance with their respective Commitment Percentages. Such Letter
of Credit Fees shall be payable quarterly in arrears on the first day of the
calendar quarter for the calendar quarter most recently ended. In respect of
each Letter of Credit, the Borrower shall also pay to the Administrative Agent
for the Administrative Agent's own account, at such other time or times as such
charges are customarily made by the Administrative Agent, the Administrative
Agent's customary issuance, amendment, negotiation or document examination and
other administrative fees as in effect from time to time.

                         5. CERTAIN GENERAL PROVISIONS.

     5.1. CLOSING FEES. The Borrower agrees to pay to the Administrative Agent
on the Closing Date a closing fee (the "CLOSING FEE") as set forth in the Fee
Letter.

     5.2. ADMINISTRATIVE AGENT'S FEE. The Borrower shall pay to the
Administrative Agent, for the Administrative Agent's own account, an
Administrative Agent's fee as set forth in the Fee Letter.

     5.3. FUNDS FOR PAYMENTS.

            5.3.1. PAYMENTS TO ADMINISTRATIVE AGENT. All payments of principal,
     interest, Reimbursement Obligations, Fees and any other amounts due
     hereunder or under any of the other Loan Documents shall be made on the due
     date thereof to the Administrative Agent in Dollars (other than
     Reimbursement Obligations for Letters of Credit issued in a currency other
     than Dollars, which shall be paid in the currency in which such Letter of
     Credit was issued), for the respective accounts of the Lenders and the
     Administrative Agent, at the Administrative Agent's Office or at such other
     place that the Administrative Agent may from time to time designate, in
     each case at or about 11:00 a.m. (Boston, Massachusetts, time or other
     local time at the place of payment) and in immediately available funds.

            5.3.2. NO OFFSET, ETC. All payments by the Borrower hereunder and
     under any of the other Loan Documents shall be made without recoupment,
     setoff or counterclaim and free and clear of and without deduction for any
     taxes, levies, imposts, duties, charges, fees, deductions, withholdings,
     compulsory loans, restrictions or conditions of any nature now or hereafter
     imposed or levied by any jurisdiction or any political subdivision thereof
     or taxing or other authority therein unless the Borrower is compelled by
     law to make such deduction or withholding. Subject to the provisions of
     Section 5.3.3 hereof, if any such obligation is imposed upon the Borrower
     with respect to any amount payable by it hereunder or under any of the
     other Loan Documents, the Borrower will pay to the Administrative Agent,
     for the account of the Lenders or (as the case may be)

<Page>

                                      -29-

     the Administrative Agent, on the date on which such amount is due and
     payable hereunder or under such other Loan Document, such additional amount
     in Dollars as shall be necessary to enable the Lenders or the
     Administrative Agent to receive the same net amount which the Lenders or
     the Administrative Agent would have received on such due date had no such
     obligation been imposed upon the Borrower. The Borrower will deliver
     promptly to the Administrative Agent certificates or other valid vouchers
     for all taxes or other charges deducted from or paid with respect to
     payments made by the Borrower hereunder or under such other Loan Document.

            5.3.3. NON-U.S. LENDERS. Each Lender and the Administrative Agent
     that is not a U.S. Person as defined in Section 7701(a)(30) of the Code for
     federal income tax purposes (a "NON-U.S. LENDER") hereby agrees that prior
     to becoming a Lender hereunder, and as and when required by the Code or
     Treasurer Regulations issued pursuant thereto, it shall deliver to the
     Borrower and the Administrative Agent, as applicable, such certificates,
     documents or other evidence, including (a) in the case of a Non-U.S. Lender
     that is a "bank" for purposes of Section 881(c)(3)(A) of the Code, two (2)
     duly completed copies of Internal Revenue Service Form W-8BEN or Form
     W-8ECI and any other certificate or statement of exemption required by
     Treasury Regulations, or any subsequent versions thereof or successors
     thereto, properly completed and duly executed by such Lender or the
     Administrative Agent establishing that with respect to payments of
     principal, interest or fees hereunder it is (i) not subject to United
     States federal withholding tax under the Code because such payment is
     effectively connected with the conduct by such Lender or Administrative
     Agent of a trade or business in the United States or (ii) totally exempt or
     partially exempt from United States federal withholding tax under a
     provision of an applicable tax treaty (but if partially exempt, still will
     not subject the Borrower to any withholding tax hereunder) and (b) in the
     case of a Non-U.S. Lender that is not a "bank" for purposes of Section
     881(c)(3)(A) of the Code, a certificate in form and substance reasonably
     satisfactory to the Administrative Agent and the Borrower and to the effect
     that (i) such Non-U.S. Lender is not a "bank" for purposes of Section
     881(c)(3)(A) of the Code, is not subject to regulatory or other legal
     requirements as a bank in any jurisdiction, and has not been treated as a
     bank for purposes of any tax, securities law or other filing or submission
     made to any governmental authority, any application made to a rating agency
     or qualification for any exemption from any tax, securities law or other
     legal requirements, (ii) is not a ten (10) percent shareholder for purposes
     of Section 881(c)(3)(B) of the Code and (iii) is not a controlled foreign
     corporation receiving interest from a related person for purposes of
     Section 881(c)(3)(C) of the Code, together with a properly completed
     Internal Revenue Service Form W-8 or W-9, as applicable (or successor
     forms). Each Lender or the Administrative Agent agrees that it shall,
     promptly upon a change of its lending office or the selection of any
     additional lending office, to the extent the forms previously delivered by
     it pursuant to this section are no longer effective, and promptly upon the
     Borrower's or the Administrative Agent's reasonable request after the
     occurrence

<Page>

                                      -30-

     of any other event (including the passage of time) requiring the delivery
     of a Form W-8BEN, Form W-8ECI, Form W-8 or W-9 in addition to or in
     replacement of the forms previously delivered, deliver to the Borrower and
     the Administrative Agent, as applicable, a properly completed and executed
     Form W-8BEN, Form W-8ECI, Form W-8 or W-9, as applicable (or any successor
     forms thereto). The Borrower shall not be required to pay any additional
     amounts to any Non-U.S. Lender in respect of United States federal
     withholding tax pursuant to Section 5.3.2 above to the extent that the
     obligation to pay such additional amounts would not have arisen but for a
     failure by such Non-U.S. Lender to comply with the provisions of this
     Section 5.3.3; PROVIDED, HOWEVER, that the foregoing shall not relieve the
     Borrower of its obligation to pay additional amounts pursuant to Section
     5.3.2 in the event that, as a result of any change in any applicable law,
     treaty or governmental rule, regulation or order, or any change in
     interpretation, administration or application thereof, a Non-US Lender that
     was previously entitled to receive all payments under this Credit Agreement
     and the Revolving Credit Notes without deduction or withholding of any
     United States federal income taxes is no longer properly entitled to
     deliver forms, certificates or other evidence at a subsequent date
     establishing the fact that such Lender is not subject to withholding.

     5.4. COMPUTATIONS. All computations of interest on the Loans and of Fees
shall be based on a 360-day year and paid for the actual number of days elapsed.
Except as otherwise provided in the definition of the term "INTEREST PERIOD"
with respect to Eurodollar Rate Loans, whenever a payment hereunder or under any
of the other Loan Documents becomes due on a day that is not a Business Day, the
due date for such payment shall be extended to the next succeeding Business Day,
and interest shall accrue during such extension. The outstanding amount of the
Revolving Credit Loans as reflected on the Records from time to time shall be
considered prima facie evidence of the amounts owing thereunder.

     5.5. INABILITY TO DETERMINE EURODOLLAR RATE. In the event, prior to the
commencement of any Interest Period relating to any Eurodollar Rate Loan, the
Administrative Agent shall determine or be notified by the Required Lenders that
(a) adequate and reasonable methods do not exist for ascertaining the Eurodollar
Rate that would otherwise determine the rate of interest to be applicable to any
Eurodollar Rate Loan during any Interest Period or (b) the Eurodollar Rate
determined or to be determined for such Interest Period will not adequately and
fairly reflect the cost to the Required Lenders of making or maintaining their
Eurodollar Rate Loans during such period, the Administrative Agent shall
forthwith give notice of such determination (which shall be conclusive and
binding on the Borrower and the Lenders) to the Borrower and the Lenders. In
such event (i) any Loan Request or Conversion Request with respect to Eurodollar
Rate Loans shall be automatically withdrawn and shall be deemed a request for
Base Rate Loans, (ii) each Eurodollar Rate Loan will automatically, on the last
day of the then current Interest Period relating thereto, become a Base Rate
Loan, and (iii) the obligations of the Lenders to make Eurodollar Rate Loans
shall be suspended until the Administrative Agent or the Required Lenders
determine that the

<Page>

                                      -31-

circumstances giving rise to such suspension no longer exist, whereupon the
Administrative Agent or, as the case may be, the Administrative Agent upon the
instruction of the Required Lenders, shall so notify the Borrower and the
Lenders.

     5.6. ILLEGALITY. Notwithstanding any other provisions herein, if any
present or future law, regulation, treaty or directive or the interpretation or
application thereof shall make it unlawful for any Lender to make or maintain
Eurodollar Rate Loans, such Lender shall forthwith give notice of such
circumstances to the Borrower and the other Lenders and thereupon (a) the
commitment of such Lender to make Eurodollar Rate Loans or convert Base Rate
Loans to Eurodollar Rate Loans shall forthwith be suspended and (b) such
Lender's Revolving Credit Loans then outstanding as Eurodollar Rate Loans, if
any, shall be converted automatically to Base Rate Loans on the last day of each
Interest Period applicable to such Eurodollar Rate Loans or within such earlier
period as may be required by law. The Borrower hereby agrees promptly to pay the
Administrative Agent for the account of such Lender, upon demand by such Lender,
any additional amounts necessary to compensate such Lender for any costs
incurred by such Lender in making any conversion in accordance with this Section
5.6, including any interest or fees payable by such Lender to lenders of funds
obtained by it in order to make or maintain its Eurodollar Rate Loans hereunder.

     5.7. ADDITIONAL COSTS, ETC. If any present or future applicable law, which
expression, as used herein, includes statutes, rules and regulations thereunder
and interpretations thereof by any competent court or by any governmental or
other regulatory body or official charged with the administration or the
interpretation thereof and requests, directives, instructions and notices at any
time or from time to time hereafter made upon or otherwise issued to any Lender
or the Administrative Agent by any central bank or other fiscal, monetary or
other authority (whether or not having the force of law), shall:

            (a)     subject any Lender or the Administrative Agent to any tax,
     levy, impost, duty, charge, fee, deduction or withholding of any nature
     with respect to this Credit Agreement, the other Loan Documents, any
     Letters of Credit, such Lender's Commitment or the Revolving Credit Loans
     (other than taxes based upon or measured by the income or profits of such
     Lender or the Administrative Agent), or

            (b)     materially change the basis of taxation (except for changes
     in taxes on income or profits) of payments to any Lender of the principal
     of or the interest on any Revolving Credit Loans or any other amounts
     payable to any Lender or the Administrative Agent under this Credit
     Agreement or any of the other Loan Documents, or

            (c)     impose or increase or render applicable (other than to the
     extent specifically provided for elsewhere in this Credit Agreement) any
     special deposit, reserve, assessment, liquidity, capital adequacy or other
     similar requirements (whether or not having the force of law) against
     assets held by, or

<Page>

                                      -32-

     deposits in or for the account of, or loans by, or letters of credit issued
     by, or commitments of an office of any Lender, or

            (d)     impose on any Lender or the Administrative Agent any other
     conditions or requirements with respect to this Credit Agreement, the other
     Loan Documents, any Letters of Credit, the Revolving Credit Loans, such
     Lender's Commitment, or any class of loans, letters of credit or
     commitments of which any of the Revolving Credit Loans or such Lender's
     Commitment forms a part, and the result of any of the foregoing is

                    (i)     to increase the cost to any Lender of making,
            funding, issuing, renewing, extending or maintaining any of the
            Revolving Credit Loans or such Lender's Commitment or any Letter of
            Credit, or

                    (ii)    to reduce the amount of principal, interest,
            Reimbursement Obligation or other amount payable to such Lender or
            the Administrative Agent hereunder on account of such Lender's
            Commitment, any Letter of Credit or any of the Revolving Credit
            Loans, or

                    (iii)   to require such Lender or the Administrative Agent
            to make any payment or to forego any interest or Reimbursement
            Obligation or other sum payable hereunder, the amount of which
            payment or foregone interest or Reimbursement Obligation or other
            sum is calculated by reference to the gross amount of any sum
            receivable or deemed received by such Lender or the Administrative
            Agent from the Borrower hereunder,

then, and in each such case, the Borrower will, upon demand made by such Lender
or (as the case may be) the Administrative Agent at any time and from time to
time and as often as the occasion therefor may arise, pay to such Lender or the
Administrative Agent such additional amounts as will be sufficient to compensate
such Lender or the Administrative Agent for such additional cost, reduction,
payment or foregone interest or Reimbursement Obligation or other sum, PROVIDED
that the Borrower shall not be liable to any Lender or the Administrative Agent
for costs incurred more than ninety (90) days prior to receipt by the Borrower
of such demand for payment from such Lender or, as the case may be, the
Administrative Agent, unless such costs were incurred prior to such one hundred
eighty (180) day period as a result of such present or future applicable law
being retroactive to a date which occurred prior to such ninety (90) day period
and such Lender or, as the case may be, the Administrative Agent, has given
notice to the Borrower of the effectiveness of such law within ninety (90) days
after the effective date thereof.

     5.8. CAPITAL ADEQUACY. If after the date hereof any Lender or the
Administrative Agent determines that (a) the adoption of or change in any law,
governmental rule, regulation, policy, guideline or directive (whether or not
having the force of law) regarding capital requirements for banks or bank
holding companies or any change in

<Page>

                                      -33-

the interpretation or application thereof by a Governmental Authority with
appropriate jurisdiction, or (b) compliance by such Lender or the Administrative
Agent or any corporation controlling such Lender or the Administrative Agent
with any law, governmental rule, regulation, policy, guideline or directive
(whether or not having the force of law) of any such entity regarding capital
adequacy, has the effect of reducing the return on such Lender's or the
Administrative Agent's commitment with respect to any Revolving Credit Loans to
a level below that which such Lender or the Administrative Agent could have
achieved but for such adoption, change or compliance (taking into consideration
such Lender's or the Administrative Agent's then existing policies with respect
to capital adequacy and assuming full utilization of such entity's capital) by
any amount deemed by such Lender or (as the case may be) the Administrative
Agent to be material, then such Lender or the Administrative Agent may notify
the Borrower of such fact. To the extent that the amount of such reduction in
the return on capital is not reflected in the Base Rate, the Borrower and such
Lender shall thereafter attempt to negotiate in good faith, within thirty (30)
days of the day on which the Borrower receives such notice, an adjustment
payable hereunder that will adequately compensate such Lender in light of these
circumstances. If the Borrower and such Lender are unable to agree to such
adjustment within thirty (30) days of the date on which the Borrower receives
such notice, then commencing on the date of such notice (but not earlier than
the effective date of any such increased capital requirement), the fees payable
hereunder shall increase by an amount that will, in such Lender's reasonable
determination, provide adequate compensation, PROVIDED that the Borrower shall
not be liable to any Lender or the Administrative Agent for costs incurred more
than ninety (90) days prior to receipt by the Borrower of the notice referred to
in the immediately preceding sentence from such Lender or the Administrative
Agent, as the case may be. Each Lender shall allocate such cost increases among
its customers in good faith and on an equitable basis.

     5.9. CERTIFICATE. A certificate setting forth any additional amounts
payable pursuant to Sections 5.7 or 5.8 and a brief explanation of such amounts
which are due, submitted by any Lender or the Administrative Agent to the
Borrower, shall be conclusive, absent manifest error, that such amounts are due
and owing.

     5.10. INDEMNITY. The Borrower agrees to indemnify each Lender and to hold
each Lender harmless from and against any loss, cost or expense (excluding loss
of anticipated profits) that such Lender may sustain or incur as a consequence
of (a) default by the Borrower in payment of the principal amount of or any
interest on any Eurodollar Rate Loans as and when due and payable, including any
such loss or expense arising from interest or fees payable by such Lender to
lenders of funds obtained by it in order to maintain its Eurodollar Rate Loans,
(b) default by the Borrower in making a borrowing or conversion after the
Borrower has given (or is deemed to have given) a Loan Request or a Conversion
Request relating thereto in accordance with Section 2.6 or Section 2.7 or (c)
the making of any payment of a Eurodollar Rate Loan or the making of any
conversion of any such Revolving Credit Loan to a Base Rate Loan on a day that
is not the last day of the applicable Interest Period with respect thereto,
including interest or

<Page>

                                      -34-

fees payable by such Lender to lenders of funds obtained by it in order to
maintain any such Revolving Credit Loans.

     5.11.  INTEREST AFTER DEFAULT.

            5.11.1. OVERDUE AMOUNTS. Overdue principal and (to the extent
     permitted by applicable law) interest on the Revolving Credit Loans and all
     other overdue amounts payable hereunder or under any of the other Loan
     Documents shall bear interest compounded monthly and payable on demand at a
     rate per annum equal to two percent (2%) above the rate of interest then
     applicable thereto (or, if no rate of interest is then applicable thereto,
     the Base Rate) until such amount shall be paid in full (after as well as
     before judgment).

            5.11.2. AMOUNTS NOT OVERDUE. During the continuance of a Default or
     an Event of Default the principal of the Revolving Credit Loans not overdue
     shall, until such Default or Event of Default has been cured or remedied or
     such Default or Event of Default has been waived by the Required Lenders
     pursuant to Section 16.12, bear interest at a rate per annum equal to two
     percent (2%) above the rate of interest otherwise applicable to such
     Revolving Credit Loans pursuant to Section 2.5 (or, if no rate of interest
     is then applicable thereto, the Base Rate).

     5.12. REPLACEMENT OF LENDERS. If any Lender (an "AFFECTED LENDER") (a)
makes demand upon the Borrower for (or if the Borrower is otherwise required to
pay) amounts pursuant to Sections 5.7 or 5.8, (b) is unable to make or maintain
Eurodollar Rate Loans as a result of a condition described in Section 5.6 or (c)
defaults in its obligation to make Revolving Credit Loans in accordance with the
terms of this Credit Agreement or purchase any Letter of Credit Participation,
the Borrower may, so long as no Default or Event of Default has occurred and is
then continuing, within ninety (90) days of receipt of such demand, notice (or
the occurrence of such other event causing the Borrower to be required to pay
such compensation or causing Section 5.6 to be applicable), or default, as the
case may be, by notice (a "REPLACEMENT NOTICE") in writing to the Administrative
Agent and such Affected Lender (i) request the Affected Lender to cooperate with
the Borrower in obtaining a replacement Lender satisfactory to the
Administrative Agent and the Borrower (the "REPLACEMENT LENDER"); (ii) request
the non-Affected Lenders to acquire and assume all of the Affected Lender's
Revolving Credit Loans and Commitment as provided herein, but none of such
Lenders shall be under an obligation to do so; or (iii) designate a Replacement
Lender approved by the Administrative Agent, such approval not to be
unreasonably withheld or delayed. If any satisfactory Replacement Lender shall
be obtained, and/or if any one or more of the non-Affected Lenders shall agree
to acquire and assume all of the Affected Lender's Revolving Credit Loans and
Commitment, then such Affected Lender shall assign, in accordance with Section
15, all of its Commitment, Revolving Credit Loans, Letter of Credit
Participations, Revolving Credit Notes and other rights and obligations under
this Credit Agreement and all other Loan Documents to such Replacement Lender or
non-Affected Lenders, as the case may be, in exchange for payment of the
principal amount so assigned and all interest and fees accrued on the amount so
assigned, plus all other Obligations then due and payable to the Affected
Lender; PROVIDED, HOWEVER, that (A) such assignment shall

<Page>

                                      -35-

be without recourse, representation or warranty and shall be on terms and
conditions reasonably satisfactory to such Affected Lender and such Replacement
Lender and/or non-Affected Lenders, as the case may be, and (B) prior to any
such assignment, the Borrower shall have paid to such Affected Lender all
amounts properly demanded and unreimbursed under Sections 5.7 and 5.8. Upon the
effective date of such assignment, the Borrower shall issue replacement
Revolving Credit Notes to such Replacement Lender and/or non-Affected Lenders,
as the case may be, and such institution shall become a "Lender" for all
purposes under this Credit Agreement and the other Loan Documents.

                                 6. GUARANTEES.

     6.1. GUARANTEES OF SUBSIDIARIES. The Obligations shall be guaranteed
pursuant to the terms of the Guaranty.

                       7. REPRESENTATIONS AND WARRANTIES.

     The Borrower represents and warrants to the Lenders and the Administrative
Agent as follows:

     good standing under the laws of its jurisdiction of incorporation or
     formation, (b) has all requisite corporate (or the equivalent company)
     power to own its property and conduct its business as now conducted and as
     presently contemplated, and (c) is in good standing as a foreign

     business in each jurisdiction where such qualification is necessary except
     where a failure to be so qualified would not have a Material Adverse
     Effect.

            7.1.2. AUTHORIZATION. The execution, delivery and performance of
     this Credit Agreement and the other Loan Documents to which the Borrower or
     any of its Subsidiaries is or is to become a party and the transactions
     contemplated hereby and thereby (a) are within the corporate (or the
     equivalent company) authority of such Person, (b) have been duly authorized
     by all necessary corporate (or the equivalent company) proceedings, (c) do

     injunction, license or permit applicable to the Borrower or any of its
     Subsidiaries and (d) do not conflict with any provision of the Governing
     Documents of, or any agreement or other instrument binding upon, the

     be expected to have a Material Adverse Effect.

                                      -36-

            7.1.3. ENFORCEABILITY. The execution and delivery of this Credit
     Agreement and the other Loan Documents to which the Borrower or any of its
     Subsidiaries is or is to become a party will result in valid and legally
     binding obligations of such Person enforceable against it in accordance
     with the respective terms and provisions hereof and thereof, except as
     enforceability is limited by bankruptcy, insolvency, reorganization,
     moratorium or other laws relating to or affecting generally the enforcement
     of creditors' rights and except to the extent that availability of the
     remedy of specific performance or injunctive relief is subject to the
     discretion of the court before which any proceeding therefor may be
     brought.

     7.2. GOVERNMENTAL APPROVALS. The execution, delivery and performance by the
Borrower and any of its Subsidiaries of this Credit Agreement and the other Loan
Documents to which the Borrower or any of its Subsidiaries is or is to become a

approval or consent of, or filing with, any governmental agency or authority
other than those already obtained.

     7.3. TITLE TO PROPERTIES; LEASES. Except as indicated on SCHEDULE 7.3
hereto, the Borrower and its Subsidiaries own all of the assets reflected in the
consolidated balance sheet of the Borrower and its Subsidiaries as at the
Balance Sheet Date or acquired since that date (except property and assets sold
or otherwise disposed of in the ordinary course of business since that date or
property and assets sold or otherwise disposed of in accordance with Section
9.5.2. hereof), subject to no Liens or other rights of others, except Permitted
Liens.

     7.4. FINANCIAL STATEMENTS, PROJECTIONS AND SOLVENCY.

            7.4.1. FISCAL YEAR. The Borrower and each of its Subsidiaries has a
     fiscal year which is the twelve months ending on December 31 of each
     calendar year.

            7.4.2. FINANCIAL STATEMENTS. There has been furnished to each of the
     Lenders a consolidated balance sheet of the Borrower and its Subsidiaries
     as at the Balance Sheet Date, and a consolidated statement of income of the
     Borrower and its Subsidiaries for the fiscal year then ended, certified by
     Ernst & Young LLP, together with a consolidated balance sheet of the
     Borrower and its Subsidiaries for the fiscal quarter ended September 30,
     2002, and a consolidated statement of income of the Borrower and its
     Subsidiaries for such fiscal quarter then ended. Each such balance sheet
     and statement of income have been prepared in accordance with GAAP and
     fairly present the financial condition of the Borrower as at the close of
     business on the date thereof and the results of operations for the fiscal
     year or fiscal quarter, as the case may be, then ended (subject to year end
     adjustments in the case of the quarterly statements). There are no
     contingent liabilities of the Borrower or any of its Subsidiaries as of
     such date involving material amounts, known to the officers of the
     Borrower, which were not disclosed in such balance sheet and the notes
     related thereto.

<Page>

                                      -37-

            7.4.3. PROJECTIONS. Copies of the projections of income statements
     of the Borrower and its Subsidiaries on a consolidated basis for the 2003
     to 2005 fiscal years have been delivered to each Lender. To the knowledge
     of the Borrower or any of its Subsidiaries, no facts exist that
     (individually or in the aggregate) would result in any material change in
     any of such projections. The projections are based upon reasonable
     estimates and assumptions, have been prepared on the basis of the
     assumptions stated therein and reflect the reasonable estimates of the
     Borrower and its Subsidiaries of the results of operations and other
     information projected therein.

            7.4.4. SOLVENCY. The Borrower on a consolidating basis, and the
     Borrower and its Subsidiaries, on a consolidated basis, both before and
     after giving effect to the transactions contemplated by this Credit
     Agreement, the other Loan Documents and all contribution arrangements among
     the Borrower and its Subsidiaries (a) are solvent, (b) the fair value of
     the property of such Person(s) exceeds its or their total liabilities
     (including contingent liabilities but without duplication of any underlying
     liability related thereto), (c) the present fair saleable value on a going
     concern basis of the assets of such Person(s) is not less than the amount
     required to pay its or their probable liabilities on its or their debts as
     they become absolute and mature, (d) do(es) not intend to, and do(es) not
     believe that it or they will, incur debts or liabilities beyond its or
     their ability to pay as such debts and liabilities mature, and (e) is or
     are not engaged, and is or are not about to engage, in business or a
     transaction for which its or their property would constitute unreasonably
     small capital.

     7.5. NO MATERIAL ADVERSE CHANGES, ETC. Since the Balance Sheet Date there
has been no event or occurrence which has had a Material Adverse Effect. Since
the Balance Sheet Date, the Borrower has not made any Restricted Payments.

     7.6. FRANCHISES, PATENTS, COPYRIGHTS, ETC. The Borrower and each of its
Subsidiaries possesses all franchises, patents, copyrights, trademarks, trade
names, licenses and permits, and rights in respect of the foregoing, adequate
for the conduct of its business substantially as now conducted without known
conflict with any rights of others.

     7.7. LITIGATION. Except as set forth in SCHEDULE 7.7 hereto, there are no
actions, suits, proceedings or investigations of any kind pending or threatened
against the Borrower or any of its Subsidiaries before any Governmental
Authority, that, (a) if adversely determined, could reasonably be expected to,
either in any case or in the aggregate, (i) have a Material Adverse Effect or
(ii) materially impair the right of the Borrower and its Subsidiaries,
considered as a whole, to carry on business substantially as now conducted by
them, or result in any substantial liability not adequately covered by
insurance, or for which adequate reserves are not maintained on the consolidated
balance sheet of the Borrower and its Subsidiaries, or (b) which question the
validity of this Credit Agreement or any of the other Loan Documents, or any
action taken or to be taken pursuant hereto or thereto.

<Page>

                                      -38-

     7.8. NO MATERIALLY ADVERSE CONTRACTS, ETC. Neither the Borrower nor any of
its Subsidiaries is subject to any Governing Document or other legal
restriction, or any judgment, decree, order, law, statute, rule or regulation
that has or is expected in the future to have a Material Adverse Effect. Neither
the Borrower nor any of its Subsidiaries is a party to any contract or agreement
that has or is expected, in the judgment of the Borrower's officers, to have any
Material Adverse Effect.

     7.9. COMPLIANCE WITH OTHER INSTRUMENTS, LAWS, ETC. Neither the Borrower nor
any of its Subsidiaries is in violation of any provision of its Governing
Documents, or any agreement or instrument to which it may be subject or by which
it or any of its properties may be bound or any decree, order, judgment,
statute, license, rule or regulation, in any of the foregoing cases in a manner
that could result in the imposition of substantial penalties or have a Material
Adverse Effect.

     7.10. TAX STATUS. The Borrower and its Subsidiaries (a) have made or filed
all federal, state and foreign income and all other tax returns, reports and
declarations required by any jurisdiction to which any of them is subject except
where the failure to so file could not reasonably be expected to have a Material
Adverse Effect, (b) have paid all taxes and other governmental assessments and
charges shown or determined to be due on such returns, reports and declarations,
except those being contested in good faith and by appropriate proceedings and
(c) have set aside on their books provisions reasonably adequate for the payment
of all taxes for periods subsequent to the periods to which such returns,
reports or declarations apply. There are no unpaid taxes in any material amount
claimed to be due by the taxing authority of any jurisdiction, and none of the
officers of the Borrower know of any basis for any such claim.

     7.11. NO EVENT OF DEFAULT. No Default or Event of Default has occurred and
is continuing.

     7.12. HOLDING COMPANY AND INVESTMENT COMPANY ACTS. Neither the Borrower nor
any of its Subsidiaries is a "HOLDING COMPANY", or a "SUBSIDIARY COMPANY" of a
"HOLDING COMPANY", or an "AFFILIATE" of a "HOLDING COMPANY", as such terms are
defined in the Public Utility Holding Company Act of 1935; nor is it an
"INVESTMENT COMPANY", or an "AFFILIATED COMPANY" or a "PRINCIPAL UNDERWRITER" of
an "INVESTMENT COMPANY", as such terms are defined in the Investment Company Act
of 1940.

     7.13. ABSENCE OF FINANCING STATEMENTS, ETC. Except with respect to
Permitted Liens, there is no financing statement, security agreement, chattel
mortgage, real estate mortgage or other document filed or recorded with any
filing records, registry or other public office, that purports to cover, affect
or give notice of any present or possible future Lien on any assets or property
of the Borrower or any of its Subsidiaries or any rights relating thereto other
than financing statements on record on the Closing Date which relate to
obligations of the Borrower or any Subsidiary which have been paid in full and
otherwise terminated and in which the Borrower has provided the Administrative
Agent with evidence of such satisfaction and termination.

<Page>

                                      -39-

     7.14. INSURANCE. The Borrower and each of its Subsidiaries maintain, with
financially sound and reputable insurers, insurance with respect to its
properties and businesses against such casualties and contingencies as are in
accordance with sound business practices.

     7.15. CERTAIN TRANSACTIONS. Except for arm's length transactions pursuant
to which the Borrower or any of its Subsidiaries makes payments in the ordinary
course of business upon terms no less favorable than the Borrower or such
Subsidiary could obtain from third parties, none of the officers, directors, or
employees of the Borrower or any of its Subsidiaries is presently a party to any
transaction with the Borrower or any of its Subsidiaries (other than for
services as employees, officers and directors), including any contract,
agreement or other arrangement providing for the furnishing of services to or
by, providing for rental of real or personal property to or from, or otherwise
requiring payments to or from any officer, director or such employee or, to the
knowledge of the Borrower, any corporation, partnership, trust or other entity
in which any officer, director, or any such employee has a substantial interest
or is an officer, director, trustee or partner.

     7.16. EMPLOYEE BENEFIT PLANS.

            7.16.1. IN GENERAL. Each Employee Benefit Plan and each Guaranteed
     Pension Plan has been maintained and operated in compliance in all material
     respects with the provisions of ERISA and all Applicable Pension
     Legislation and, to the extent applicable, the Code, including but not
     limited to the provisions thereunder respecting prohibited transactions and
     the bonding of fiduciaries and other persons handling plan funds as
     required by Section 412 of ERISA. The Borrower has heretofore delivered to
     the Administrative Agent the most recently completed annual report, Form
     5500, with all required attachments, and actuarial statement required to be
     submitted under Section 103(d) of ERISA, with respect to each Guaranteed
     Pension Plan.

            7.16.2. TERMINABILITY OF WELFARE PLANS. No Employee Benefit Plan,
     which is an employee welfare benefit plan within the meaning of Section
     3(1) or Section 3(2)(B) of ERISA, provides benefit coverage subsequent to
     termination of employment, except as required by Title I, Part 6 of ERISA
     or the applicable state insurance laws. The Borrower may terminate each
     such Plan at any time (or at any time subsequent to the expiration of any
     applicable bargaining agreement) in the discretion of the Borrower without
     liability to any Person other than for claims arising prior to termination.

            7.16.3. GUARANTEED PENSION PLANS. Each contribution required to be
     made to a Guaranteed Pension Plan, whether required to be made to avoid the
     incurrence of an accumulated funding deficiency, the notice or lien
     provisions of Section 302(f) of ERISA, or otherwise, has been timely made.
     No waiver of an accumulated funding deficiency or extension of amortization
     periods has been received with respect to any Guaranteed Pension Plan, and
     neither the Borrower nor any ERISA Affiliate is obligated to or has posted
     security in connection with

<Page>

                                      -40-

     an amendment to a Guaranteed Pension Plan pursuant to Section 307 of ERISA
     or Section 401(a)(29) of the Code. No liability to the PBGC (other than
     required insurance premiums, all of which have been paid) has been incurred
     by the Borrower or any ERISA Affiliate with respect to any Guaranteed
     Pension Plan and there has not been any ERISA Reportable Event (other than
     an ERISA Reportable Event as to which the requirement of 30 days notice has
     been waived), or any other event or condition which presents a material
     risk of termination of any Guaranteed Pension Plan by the PBGC. Based on
     the latest valuation of each Guaranteed Pension Plan (which in each case
     occurred within twelve months of the date of this representation), and on
     the actuarial methods and assumptions employed for that valuation, the
     aggregate benefit liabilities of all such Guaranteed Pension Plans within
     the meaning of Section 4001 of ERISA did not exceed the aggregate value of
     the assets of all such Guaranteed Pension Plans, disregarding for this
     purpose the benefit liabilities and assets of any Guaranteed Pension Plan
     with assets in excess of benefit liabilities.

            7.16.4. MULTI-EMPLOYER PLANS. Neither the Borrower nor any ERISA
     Affiliate has incurred any material liability (including secondary
     liability) to any Multi-employer Plan as a result of a complete or partial
     withdrawal from such Multi-employer Plan under Section 4201 of ERISA or as
     a result of a sale of assets described in Section 4204 of ERISA. Neither
     the Borrower nor any ERISA Affiliate has been notified that any
     Multi-employer Plan is in reorganization or insolvent under and within the
     meaning of Section 4241 or Section 4245 of ERISA or is at risk of entering
     reorganization or becoming insolvent, or that any Multi-employer Plan
     intends to terminate or has been terminated under Section 4041A of ERISA.

     7.17. USE OF PROCEEDS.

            7.17.1. GENERAL. The proceeds of the Revolving Credit Loans shall be
     used for working capital and general corporate purposes (including, without
     limitation, financing all or a portion of a Permitted Acquisition). The
     Borrower will obtain Letters of Credit solely for working capital and
     general corporate purposes.

            7.17.2. REGULATIONS U AND X. No portion of any Revolving Credit Loan
     is to be used, and no portion of any Letter of Credit is to be obtained,
     for the purpose of purchasing or carrying any "MARGIN SECURITY" or "MARGIN
     STOCK" (as such terms are used in Regulations U and X of the Board of
     Governors of the Federal Reserve System, 12 C.F.R. Parts 221 and 224)
     unless the purchasing or carrying of any such margin security or margin
     stock would not violate such Regulations U and/or X.

            7.17.3. INELIGIBLE SECURITIES. No portion of the proceeds of any
     Revolving Credit Loans is to be used, and no portion of any Letter of
     Credit is to be obtained, for the purpose of knowingly purchasing, or
     providing credit support for the purchase of, during the underwriting or
     placement period or

<Page>

                                      -41-

     7.18. ENVIRONMENTAL COMPLIANCE. The Borrower has taken all reasonably
necessary steps to investigate the past and present condition and usage of the
Real Estate and the operations conducted by the Borrower, its Subsidiaries or
any of its agents thereon and, based upon such diligent investigation, has
determined that:

            (a)     none of the Borrower, its Subsidiaries or any operator of
     the Real Estate or any operations thereon is in violation, or alleged
     violation, of any judgment, decree, order, law, license, rule or regulation

     or the environment (hereinafter "ENVIRONMENTAL LAWS"), which violation
     would have a Material Adverse Effect;

            (b)     neither the Borrower nor any of its Subsidiaries has

     responsible party under CERCLA with respect to a site listed on the
     National Priorities List, 40 C.F.R. Part 300 Appendix B; (ii) that any
     hazardous waste, as defined by 42 U.S.C. Section 6903(5), any hazardous

     substances, oil or hazardous materials or other chemicals or substances
     regulated by any Environmental Laws ("HAZARDOUS SUBSTANCES") which any one
     of them has generated, transported or disposed of has been found at any
     site at which a Governmental Authority has conducted or has ordered that
     the Borrower or any of its Subsidiaries conduct a remedial investigation,
     removal or other response action pursuant to any Environmental Law; or
     (iii) that it is or shall be a named party to any claim, action, cause of
     action, complaint, or legal or administrative proceeding (in each case,
     contingent or otherwise) arising out of any third party's incurrence of
     costs, expenses, losses or damages of any kind whatsoever in connection
     with the release of Hazardous Substances which, in each case, could
     reasonably be expected to have a Material Adverse Effect;

            (c)     except as set forth on SCHEDULE 7.18 attached hereto: (i) no
     portion of the Real Estate has been used for the handling, processing,
     storage or disposal of Hazardous Substances except in accordance with
     applicable Environmental Laws or where the noncompliance with such
     Environmental Laws could not reasonably be expected to have a Material
     Adverse Effect; and no underground tank or other underground storage
     receptacle for Hazardous Substances is

<Page>

                                      -42-

     located on any portion of the Real Estate; (ii) in the course of any
     activities conducted by the Borrower, its Subsidiaries or operators of its
     properties, no Hazardous Substances have been generated or are being used
     on the Real Estate except in accordance with applicable Environmental Laws
     or where the noncompliance with such Environmental Laws could not
     reasonably be expected to have a Material Adverse Effect; (iii) there have

     disposing or dumping) or threatened releases of Hazardous Substances on,

     which releases would have a material adverse effect on the value of any of
     the Real Estate or adjacent properties or the environment; (iv) to the best
     of the Borrower's knowledge, there have been no releases on, upon, from or
     into any real property in the vicinity of any of the Real Estate which,
     through soil or groundwater contamination, may have come to be located on,
     and which would have a material adverse effect on the value of, the Real
     Estate; and (v) in addition, any Hazardous Substances that have been
     generated on any of the Real Estate have been transported offsite only by
     carriers having an identification number issued by the EPA (or the
     equivalent thereof in any foreign jurisdiction), treated or disposed of
     only by treatment or disposal facilities maintaining valid permits as
     required under applicable Environmental Laws, which transporters and
     facilities have been and are, to the best of the Borrower's knowledge,
     operating in compliance with such permits and applicable Environmental
     Laws; and

            (d)     none of the Borrower and its Subsidiaries, or any of the
     Real Estate is subject to any applicable Environmental Law requiring the
     performance of Hazardous Substances site assessments, or the removal or
     remediation of Hazardous Substances, or the giving of notice to any
     Governmental Authority or the recording or delivery to other Persons of an
     environmental disclosure document or statement by virtue of the

     the effectiveness of any other transactions contemplated hereby.

     7.19. SUBSIDIARIES, ETC. SCHEDULE 7.19(a) (as the same may be amended from
time to time in accordance with Section 8.13 hereof) sets forth the only
Subsidiaries of the Borrower. Except as set forth on SCHEDULE 7.19(b) hereto,
neither the Borrower nor any Subsidiary of the Borrower is engaged in any joint

necessary in order to make the statements herein or therein not misleading.
There is no fact known to the Borrower or any of its Subsidiaries which has a
Material Adverse Effect, or which is reasonably likely

<Page>

                                      -43-

in the future to have a Material Adverse Effect, exclusive of effects resulting

conditions.

                            8. AFFIRMATIVE COVENANTS.

     The Borrower covenants and agrees that, so long as any Revolving Credit
Loan, Unpaid Reimbursement Obligation, Letter of Credit or Revolving Credit Note

     Administrative Agent and each of the Lenders in writing of the occurrence
     of any Default or Event of Default, together with a reasonably detailed
     description thereof, and the actions the Borrower proposes to take with
     respect thereto. If any Person shall give any notice or take any other
     action in respect of a claimed default under this Credit Agreement or any
     other note, evidence of indebtedness, indenture or other obligation to
     which or with respect to which the Borrower or any of its Subsidiaries is a
     party or obligor, whether as principal, guarantor, surety or otherwise, to
     the extent such claimed default would constitute an Event of

<Page>

                                      -45-

     Default hereunder if such claim were accurate, the Borrower shall forthwith

     written report supplemental to any oral report is made) to any Governmental
     Authority and (b) upon becoming aware thereof, of any inquiry, proceeding,
     investigation, or other action, including a notice from any agency of
     potential environmental liability, of any Governmental Authority that could

     Subsidiaries or to which the Borrower or any of its Subsidiaries is or
     becomes a party involving an uninsured claim against the Borrower or any of
     its Subsidiaries that could reasonably be expected to have a Material
     Adverse Effect on the Borrower or any of its Subsidiaries and stating the
     nature and status of such litigation or proceedings. The Borrower will, and
     will cause each of its Subsidiaries to, give notice to the Administrative

     covered by insurance, final or otherwise, against the Borrower or any of
     its Subsidiaries in an amount in excess of $1,000,000.

     8.6. LEGAL EXISTENCE; MAINTENANCE OF PROPERTIES. The Borrower will do or
cause to be done all things necessary to preserve and keep in full force and

businesses now conducted by them and in related businesses; PROVIDED that
nothing in this Section 8.6 shall prevent the Borrower from discontinuing the
operation and maintenance of any of its properties or any of those of its
Subsidiaries if such discontinuance is, in the judgment of the Borrower,
desirable in the conduct of its or their business and that do not in the
aggregate have a Material Adverse Effect.

     8.7. INSURANCE. The Borrower will, and will cause each of its Subsidiaries
to, maintain with financially sound and reputable insurers insurance with

imposed upon it and its Real Estate, sales and activities, or any part thereof,
or upon the income or profits therefrom, as well as all claims for labor,
materials, or supplies that if unpaid might by law become a Lien or charge upon
any of its property; PROVIDED that any such tax, assessment, charge, levy or
claim need not be paid if the validity or amount thereof shall currently be
contested in good faith by appropriate proceedings and if the Borrower or such
Subsidiary shall have set aside on its books adequate reserves with respect
thereto; and PROVIDED FURTHER that the Borrower and each Subsidiary of the
Borrower will pay all such taxes, assessments, charges, levies or claims
forthwith upon the commencement of proceedings to foreclose any Lien that may
have attached as security therefor.

     8.9. INSPECTION RIGHTS. No more frequently than once each calendar year, or
more frequently as determined by the Administrative Agent if an Event of Default
shall have occurred and be continuing, the Borrower shall permit the Lenders,
through the Administrative Agent or any of the Lenders' other designated
representatives, to visit and inspect any of the properties of the Borrower or
any of its Subsidiaries, to examine the books of account of the Borrower and its
Subsidiaries (and to make copies thereof and extracts therefrom), and to discuss
the affairs, finances and accounts of the Borrower and its Subsidiaries with,
and to be advised as to the same by, its and their officers, all at such

and is continuing, upon prior written notice by the Administrative Agent, as the
Administrative Agent or any Lender may reasonably request.

     8.10. COMPLIANCE WITH LAWS, CONTRACTS, LICENSES, AND PERMITS. The Borrower
will, and will cause each of its Subsidiaries to, comply with (a) the applicable
laws and regulations wherever its business is conducted, including all
Environmental Laws, except where the failure to so comply could not reasonably
be expected to have a Material Adverse Effect (b) the provisions of its
Governing Documents except where the failure to so comply could not reasonably
be expected to have a Material Adverse Effect, (c) all agreements and
instruments by which it or any of its properties may be bound, except where the
failure to so comply could not reasonably be expected to have a

                                      -47-

Material Adverse Effect and (d) all applicable decrees, orders, and judgments,
except where the failure to so comply could not reasonably be expected to have a
Material Adverse Effect. If any authorization, consent, approval, permit or
license from any officer, agency or instrumentality of any government shall
become necessary or required in order that the Borrower or any of its
Subsidiaries may fulfill any of its obligations hereunder or any of the other
Loan Documents to which the Borrower or such Subsidiary is a party, the Borrower
will, or (as the case may be) will cause such Subsidiary to, immediately take or

Loans or the Administrative Agent has any obligations to issue, extend or renew
any Letters of Credit:

     Section 4068 of ERISA; or

            (d)     amend any Guaranteed Pension Plan in circumstances requiring

            (l)     the Borrower or any of its Subsidiaries shall be enjoined,
     restrained or in any way prevented by the order of any Governmental
     Authority from conducting any material part of its business which could
     reasonably be expected to have a Material Adverse Effect and such order
     shall continue in effect for more than thirty (30) days;

            (m)     there shall occur any strike, lockout, labor dispute,
     embargo, condemnation, act of God or public enemy, or other casualty, which
     in any such case causes, for more than fifteen (15) consecutive days, the
     cessation or substantial curtailment of revenue producing activities at any
     facility of the Borrower or any of its Subsidiaries if such event or
     circumstance is not covered by business interruption insurance and would
     have a Material Adverse Effect; or

            (n)     a Change of Control shall occur;

then, and in any such event, so long as the same may be continuing, the

Credit Agreement, the Revolving Credit Notes and the other Loan Documents and

immediately due and payable without presentment, demand, protest or other notice

the Reimbursement Obligations, may, with the consent of the Required Lenders but
not otherwise, proceed to protect and enforce its rights by suit in equity,
action at law or other appropriate proceeding, whether for the specific
performance of any covenant or agreement contained in this

<Page>

                                      -63-

Credit Agreement and the other Loan Documents or any instrument pursuant to
which the Obligations to such Lender are evidenced, including as permitted by
applicable law the obtaining of the EX PARTE appointment of a receiver, and, if
such amount shall have become due, by declaration or otherwise, proceed to
enforce the payment thereof or any other legal or equitable right of such
Lender. No remedy herein conferred upon any Lender or the Administrative Agent
or the holder of any Revolving Credit Note or purchaser of any Letter of Credit
Participation is intended to be exclusive of any other remedy and each and every
remedy shall be cumulative and shall be in addition to every other remedy given
hereunder or now or hereafter existing at law or in equity or by statute or any
other provision of law.

     13.4. DISTRIBUTION OF PROCEEDS. In the event that the Administrative Agent
or any Lender, as the case may be, receives any monies in connection with the
enforcement of any the Loan Documents, such monies shall be distributed for
application as follows:

            (a)     First, to the payment of, or (as the case may be) the
     reimbursement of the Administrative Agent for or in respect of all
     reasonable costs, expenses, disbursements and losses which shall have been
     incurred or sustained by the Administrative Agent in connection with the
     collection of such monies by the Administrative Agent, for the exercise,
     protection or enforcement by the Administrative Agent of all or any of the
     rights, remedies, powers and privileges of the Administrative Agent under
     this Credit Agreement or any of the other Loan Documents or in support of
     any provision of adequate indemnity to the Administrative Agent against any
     taxes or liens which by law shall have, or may have, priority over the
     rights of the Administrative Agent to such monies;

            (b)     Second, to all other Obligations in such order or preference
     as the Required Lenders may determine; PROVIDED, HOWEVER, that (i)
     distributions shall be made (A) PARI PASSU among Obligations with respect
     to the Administrative Agent's Fee and all other Obligations and (B) with
     respect to each type of Obligation owing to the Lenders, such as interest,
     principal, fees and expenses, among the Lenders PRO RATA, and (ii) the
     Administrative Agent may in its discretion make proper allowance to take
     into account any Obligations not then due and payable;

            (c)     Third, upon payment and satisfaction in full or other
     provisions for payment in full satisfactory to the Lenders and the
     Administrative Agent of all of the Obligations, to the extent applicable,

     9-608(a)(1)(C) or 9-615(a)(3) of the Uniform Commercial Code of the
     Commonwealth of Massachusetts; and

            (d)     Fourth, the excess, if any, shall be returned to the
     Borrower or to such other Persons as are entitled thereto.

                          14. THE ADMINISTRATIVE AGENT.

     14.1. AUTHORIZATION.

<Page>

                                      -64-

            (a)     The Administrative Agent is authorized to take such action
     on behalf of each of the Lenders and to exercise all such powers as are
     hereunder and under any of the other Loan Documents and any related
     documents delegated to the Administrative Agent, together with such powers
     as are reasonably incident thereto, PROVIDED that no duties or
     responsibilities not expressly assumed herein or therein shall be implied
     to have been assumed by the Administrative Agent.

            (b)     The relationship between the Administrative Agent and each
     of the Lenders is that of an independent contractor. The use of the term
     "ADMINISTRATIVE AGENT" is for convenience only and is used to describe, as
     a form of convention, the independent contractual relationship between the
     Administrative Agent and each of the Lenders. Nothing contained in this
     Credit Agreement nor the other Loan Documents shall be construed to create
     an agency, trust or other fiduciary relationship between the Administrative
     Agent and any of the Lenders.

            (c)     As an independent contractor empowered by the Lenders to
     exercise certain rights and perform certain duties and responsibilities
     hereunder and under the other Loan Documents, the Administrative Agent is
     nevertheless a "REPRESENTATIVE" of the Lenders, as that term is defined in
     Article 1 of the Uniform Commercial Code, for purposes of actions for the
     benefit of the Lenders and the Administrative Agent with respect to all
     guarantees contemplated by the Loan Documents.

     14.2. EMPLOYEES AND ADMINISTRATIVE AGENTS. The Administrative Agent may
exercise its powers and execute its duties by or through employees or agents and
shall be entitled to take, and to rely on, advice of counsel concerning all
matters pertaining to its rights and duties under this Credit Agreement and the
other Loan Documents. The Administrative Agent may utilize the services of such
Persons as the Administrative Agent in its sole discretion may reasonably
determine, and all reasonable fees and expenses of any such Persons shall be
paid by the Borrower.

     14.3. NO LIABILITY. Neither the Administrative Agent nor any of its
shareholders, directors, officers or employees nor any other Person assisting
them in their duties nor any agent or employee thereof, shall be liable to any
Lender for any waiver, consent or approval given or any action taken, or omitted
to be taken, in good faith by it or them hereunder or under any of the other
Loan Documents, or in connection herewith or therewith, or be responsible to any
Lender for the consequences of any oversight or error of judgment whatsoever,
except that the Administrative Agent or such other Person, as the case may be,
may be liable for losses due to its willful misconduct or gross negligence. The
Administrative Agent shall be fully justified in failing or refusing to take any
action under this Credit Agreement unless it shall first have received such
advice or concurrence of the Required Lenders as it reasonably deems appropriate
or it shall first be indemnified to its reasonable satisfaction by the Lenders
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action. The Administrative Agent shall
in all

<Page>

                                      -65-

cases be fully protected in acting, or in refraining from acting, under this
Credit Agreement in accordance with a request of the Required Lenders, and such
request and any action taken or failure to act pursuant thereto shall be binding
upon the Lenders and all future holders of the Revolving Credit Notes or of a
Letter of Credit Participation.

     14.4. NO REPRESENTATIONS.

            14.4.1. GENERAL. The Administrative Agent shall not be responsible
     for the execution or validity or enforceability of this Credit Agreement,
     the Revolving Credit Notes, the Letters of Credit, any of the other Loan
     Documents or any instrument at any time constituting, or intended to
     constitute, collateral security for the Revolving Credit Notes, or for the
     value of any such collateral security or for the validity, enforceability
     or collectability of any such amounts owing with respect to the Revolving
     Credit Notes, or for any recitals or statements, warranties or
     representations made herein or in any of the other Loan Documents or in any
     certificate or instrument hereafter furnished to it by or on behalf of the
     Borrower or any of its Subsidiaries, or be bound to ascertain or inquire as
     to the performance or observance of any of the terms, conditions, covenants
     or agreements herein or in any instrument at any time constituting, or
     intended to constitute, collateral security for the Revolving Credit Notes
     or to inspect any of the properties, books or records of the Borrower or
     any of its Subsidiaries. The Administrative Agent shall not be bound to
     ascertain whether any notice, consent, waiver or request delivered to it by
     the Borrower or any holder of any of the Revolving Credit Notes shall have
     been duly authorized or is true, accurate and complete. The Administrative
     Agent has not made nor does it now make any representations or warranties,
     express or implied, nor does it assume any liability to the Lenders, with
     respect to the credit worthiness or financial conditions of the Borrower or
     any of its Subsidiaries. Each Lender acknowledges that it has,
     independently and without reliance upon the Administrative Agent or any
     other Lender, and based upon such information and documents as it has
     deemed appropriate, made its own credit analysis and decision to enter into
     this Credit Agreement.

            14.4.2. CLOSING DOCUMENTATION, ETC. For purposes of determining
     compliance with the conditions set forth in Section 11, each Lender that
     has executed this Credit Agreement shall be deemed to have consented to,
     approved or accepted, or to be satisfied with, each document and matter
     either sent, or made available, by the Administrative Agent to such Lender
     for consent, approval, acceptance or satisfaction, or required thereunder
     to be consented to or approved by or acceptable or satisfactory to such
     Lender, unless an officer of the Administrative Agent active upon the
     Borrower's account shall have received notice from such Lender prior to the
     Closing Date specifying such Lender's objection thereto and such objection
     shall not have been withdrawn by notice to the Administrative Agent to such
     effect on or prior to the Closing Date.

     14.5. PAYMENTS.

<Page>

                                      -66-

            14.5.1. PAYMENTS TO ADMINISTRATIVE AGENT. A payment by the Borrower
     to the Administrative Agent hereunder or any of the other Loan Documents
     for the account of any Lender shall constitute a payment to such Lender.
     The Administrative Agent agrees promptly to distribute to each Lender such
     Lender's PRO RATA share of payments received by the Administrative Agent
     for the account of the Lenders except as otherwise expressly provided
     herein or in any of the other Loan Documents.

            14.5.2. DISTRIBUTION BY ADMINISTRATIVE AGENT. If in the opinion of
     the Administrative Agent the distribution of any amount received by it in
     such capacity hereunder, under the Revolving Credit Notes or under any of
     the other Loan Documents might involve it in liability, it may refrain from
     making distribution until its right to make distribution shall have been
     adjudicated by a court of competent jurisdiction. If a court of competent
     jurisdiction shall adjudge that any amount received and distributed by the
     Administrative Agent is to be repaid, each Person to whom any such
     distribution shall have been made shall either repay to the Administrative
     Agent its proportionate share of the amount so adjudged to be repaid or
     shall pay over the same in such manner and to such Persons as shall be
     determined by such court.

            14.5.3. DELINQUENT LENDERS. Notwithstanding anything to the contrary
     contained in this Credit Agreement or any of the other Loan Documents, any
     Lender that fails (a) to make available to the Administrative Agent its PRO
     RATA share of any Revolving Credit Loan or to purchase any Letter of Credit
     Participation or (b) to comply with the provisions of Section 16.1 with
     respect to making dispositions and arrangements with the other Lenders,
     where such Lender's share of any payment received, whether by setoff or
     otherwise, is in excess of its PRO RATA share of such payments due and
     payable to all of the Lenders, in each case as, when and to the full extent
     required by the provisions of this Credit Agreement, shall be deemed
     delinquent (a "DELINQUENT LENDER") and shall be deemed a Delinquent Lender
     until such time as such delinquency is satisfied. A Delinquent Lender shall
     be deemed to have assigned any and all payments due to it from the
     Borrower, whether on account of outstanding Revolving Credit Loans, Unpaid
     Reimbursement Obligations, interest, fees or otherwise, to the remaining
     nondelinquent Lenders for application to, and reduction of, their
     respective PRO RATA shares of all outstanding Revolving Credit Loans and
     Unpaid Reimbursement Obligations. The Delinquent Lender hereby authorizes
     the Administrative Agent to distribute such payments to the nondelinquent
     Lenders in proportion to their respective PRO RATA shares of all
     outstanding Revolving Credit Loans and Unpaid Reimbursement Obligations. A
     Delinquent Lender shall be deemed to have satisfied in full a delinquency
     when and if, as a result of application of the assigned payments to all
     outstanding Revolving Credit Loans and Unpaid Reimbursement Obligations of
     the nondelinquent Lenders, the Lenders' respective PRO RATA shares of all
     outstanding Revolving Credit Loans and Unpaid Reimbursement Obligations
     have returned to those in effect

<Page>

                                      -67-

     immediately prior to such delinquency and without giving effect to the
     nonpayment causing such delinquency.

     14.6. HOLDERS OF REVOLVING CREDIT NOTES. The Administrative Agent may deem
and treat the payee of any Revolving Credit Note or the purchaser of any Letter
of Credit Participation as the absolute owner or purchaser thereof for all
purposes hereof until it shall have been furnished in writing with a different
name by such payee or by a subsequent holder, assignee or transferee.

     14.7. INDEMNITY. The Lenders ratably agree hereby to indemnify and hold
harmless the Administrative Agent and its affiliates from and against any and
all claims, actions and suits (whether groundless or otherwise), losses,
damages, costs, expenses (including any expenses for which the Administrative
Agent or such affiliate has not been reimbursed by the Borrower as required by
Section 15.2), and liabilities of every nature and character arising out of or
related to this Credit Agreement, the Revolving Credit Notes, or any of the
other Loan Documents or the transactions contemplated or evidenced hereby or
thereby, or the Administrative Agent's actions taken hereunder or thereunder,
except to the extent that any of the same shall be directly caused by the
Administrative Agent's willful misconduct or gross negligence.

     14.8. ADMINISTRATIVE AGENT AS LENDER. In its individual capacity, Fleet
shall have the same obligations and the same rights, powers and privileges in
respect to its Commitment and the Revolving Credit Loans made by it, and as the
holder of any of the Revolving Credit Notes and as the purchaser of any Letter
of Credit Participations, as it would have were it not also the Administrative
Agent.

     14.9. RESIGNATION. The Administrative Agent may resign at any time by
giving sixty (60) days prior written notice thereof to the Lenders and the
Borrower. Upon any such resignation, the Required Lenders shall have the right
to appoint a successor Administrative Agent. If no successor Administrative
Agent shall have been so appointed by the Required Lenders and shall have
accepted such appointment within thirty (30) days after the retiring
Administrative Agent's giving of notice of resignation, then the retiring
Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, which shall be a financial institution having a rating of
not less than A or its equivalent by S&P. In all cases, unless a Default or
Event of Default shall have occurred and be continuing, such successor
Administrative Agent shall be reasonably acceptable to the Borrower. Upon the
acceptance of any appointment as Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Administrative Agent, and the retiring Administrative Agent
shall be discharged from its duties and obligations hereunder. After any
retiring Administrative Agent's resignation, the provisions of this Credit
Agreement and the other Loan Documents shall continue in effect for its benefit
in respect of any actions taken or omitted to be taken by it while it was acting
as Administrative Agent.

     14.10. ADMINISTRATIVE AGENT MAY FILE PROOFS OF CLAIM.

<Page>

                                      -68-

            (a)     In case of the pendency of any receivership, insolvency,
     liquidation, bankruptcy, reorganization, arrangement, adjustment,
     composition or other judicial, administrative or like proceeding or any
     assignment for the benefit of creditors relative to the Borrower or any of
     its Subsidiaries, the Administrative Agent (irrespective of whether the
     principal of any Revolving Credit Loan, Reimbursement Obligation or Unpaid
     Reimbursement Obligation shall then be due and payable as herein expressed
     or by declaration or otherwise and irrespective of whether the
     Administrative Agent shall have made any demand on the Borrower) shall be
     entitled and empowered, by intervention in such proceeding, under any such
     assignment or otherwise:

                    (i)     to file and prove a claim for the whole amount of
            the principal and interest owing and unpaid in respect of the
            Revolving Credit Loans, Reimbursement Obligations or Unpaid
            Reimbursement Obligations and all other Obligations that are owing
            and unpaid and to file such other documents as may be necessary or
            advisable in order to have the claims of the Lenders and the
            Administrative Agent (including any claim for the reasonable
            compensation, expenses, disbursements and advances of the Lenders
            and the Administrative Agent and their respective agents and counsel
            and all other amounts due the Lenders and the Administrative Agent
            under Sections 2.2, 4.6, 5.1, 5.2 and 16.2) allowed in such
            proceeding or under any such assignment; and

                    (ii)    to collect and receive any monies or other property
            payable or deliverable on any such claims and to distribute the
            same;

            (b)     Any custodian, receiver, assignee, trustee, liquidator,
     sequestrator or other similar official in any such proceeding or under any
     such assignment is hereby authorized by each Lender to make such payments
     to the Administrative Agent and, in the event that the Administrative Agent
     shall consent to the making of such payments directly to the Lenders,
     nevertheless to pay to the Administrative Agent any amount due for the
     reasonable compensation, expenses, disbursements and advances of the
     Administrative Agent and its agents and counsel, and any other amounts due
     the Administrative Agent under Sections 2.2, 4.6, 5.1, 5.2 and 16.2.

            (c)     Nothing contained herein shall authorize the Administrative
     Agent to consent to or accept or adopt on behalf of any Lender any plan of
     reorganization, arrangement, adjustment or composition affecting the
     Obligations owed to such Lender or the rights of any Lender or to authorize
     the Administrative Agent to vote in respect of the claim of any Lender in
     any such proceeding or under any such assignment.

<Page>

                                      -69-

     14.11. NOTIFICATION OF DEFAULTS AND EVENTS OF DEFAULT. Each Lender hereby
agrees that, upon learning of the existence of a Default or an Event of Default,
it shall promptly notify the Administrative Agent thereof. The Administrative
Agent hereby agrees that upon receipt of any notice under this Section 14.10 it
shall promptly notify the other Lenders of the existence of such Default or
Event of Default.

     14.12. DUTIES IN THE CASE OF ENFORCEMENT. In case one of more Events of
Default have occurred and shall be continuing, and whether or not acceleration
of the Obligations shall have occurred, the Administrative Agent shall, if (a)
so requested by the Required Lenders and (b) the Lenders have provided to the
Administrative Agent such additional indemnities and assurances against expenses
and liabilities as the Administrative Agent may reasonably request, proceed to
enforce the provisions of the Loan Documents. The Required Lenders may direct
the Administrative Agent in writing as to the method and the extent of any such
sale or other disposition, the Lenders hereby agreeing to indemnify and hold the
Administrative Agent, harmless from all liabilities incurred in respect of all
actions taken or omitted in accordance with such directions, PROVIDED that the
Administrative Agent need not comply with any such direction to the extent that
the Administrative Agent reasonably believes the Administrative Agent's
compliance with such direction to be unlawful or commercially unreasonable in
any applicable jurisdiction.

                           15. SUCCESSORS AND ASSIGNS.

     15.1. GENERAL CONDITIONS. The provisions of this Credit Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns permitted hereby, except that the Borrower may not assign
or otherwise transfer any of its rights or obligations hereunder without the
prior written consent of each Lender and no Lender may assign or otherwise
transfer any of its rights or obligations hereunder except (a) to an Eligible
Assignee in accordance with the provisions of Section 15.2, (b) by way of
participation in accordance with the provisions of Section 15.4 or (c) by way of
pledge or assignment of a security interest subject to the restrictions of
Section 15.6 (and any other attempted assignment or transfer by any party hereto
shall be null and void). Nothing in this Credit Agreement, expressed or implied,
shall be construed to confer upon any Person (other than the parties hereto,
their respective successors and assigns permitted hereby, Participants to the
extent provided in Section 15.4 and, to the extent expressly contemplated
hereby, the Related Parties of each of the Administrative Agent and the Lenders)
any legal or equitable right, remedy or claim under or by reason of this Credit
Agreement or any of the other Loan Documents.

     15.2. ASSIGNMENTS. Any Lender may at any time assign to one or more
Eligible Assignees all or a portion of its rights and obligations under this
Credit Agreement (including all or a portion of its Commitment and the Revolving
Credit Loans at the time owing to it); PROVIDED that (a) except in the cases of
an assignment of the entire remaining amount of the assigning Lender's
Commitment and the Revolving Credit Loans at the time owing to it or, of an
assignment to a Lender or a Lender Affiliate, the

<Page>

                                      -70-

aggregate amount of the Commitment (which for this purpose includes Revolving
Credit Loans outstanding thereunder) or, if the applicable Commitment is not
then in effect, the principal outstanding balance of the Revolving Credit Loan
of the assigning Lender subject to each such assignment (determined as of the
date on which the Assignment and Acceptance with respect to such assignment is
delivered to the Administrative Agent) shall not be less than $1,000,000 unless
each of the Administrative Agent and, so long as no Default or Event of Default
has occurred and is continuing, the Borrower otherwise consent (each such
consent not to be unreasonably withheld or delayed); (b) each partial assignment
shall be made as an assignment of a proportionate part of all the assigning
Lender's rights and obligations under this Credit Agreement with respect to the
Revolving Credit Loan or the Commitment assigned, it being understood that
non-PRO RATA assignments of or among any of the Commitments, the Revolving
Credit Loans, and the Reimbursement Obligations are not permitted; (c) any
assignment of a Commitment must be approved by the Administrative Agent and,
unless an Event of Default has occurred and is continuing, the Borrower, unless
the Person that is the proposed assignee is itself a Lender with a Commitment
(whether or not the proposed assignee would otherwise qualify as an Eligible
Assignee); and (d) the parties to each assignment shall execute and deliver to
the Administrative Agent an Assignment and Acceptance, together with a
processing and recordation fee of $2,500, and the Eligible Assignee, if it shall
not be a Lender, shall deliver to the Administrative Agent an Administrative
Questionnaire. Subject to acceptance and recording thereof by the Administrative
Agent pursuant to Section 15.3, from and after the effective date specified in
each Assignment and Acceptance, the Eligible Assignee thereunder shall be a
party to this Credit Agreement and, to the extent of the interest assigned by
such Assignment and Acceptance have the rights and obligations of a Lender under
this Credit Agreement, and the assigning Lender thereunder shall, to the extent
of the interest assigned by such Assignment and Acceptance, be released from its
obligations under this Credit Agreement (and, in the case of an Assignment and
Acceptance covering all of the assigning Lender's rights and obligations under
this Credit Agreement, such Lender shall cease to be a party hereto) but shall
continue to be entitled to the benefits of Sections 5.3.2, 5.7, 5.8, 5.10 and
16.3 with respect to facts and circumstances occurring prior to the effective
date of such assignment. Any assignment or transfer by a Lender of rights or
obligations under this Credit Agreement that does not comply with this paragraph
shall be treated for purposes of this Credit Agreement as a sale by such Lender
of a participation in such rights and obligations in accordance with Section
15.4.

     15.3. REGISTER. The Administrative Agent, acting solely for this purpose as
an agent of the Borrower, shall maintain at the Administrative Agent's Office a
copy of each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitments of,
and principal amounts of the Revolving Credit Loans owing to, each Lender
pursuant to the terms hereof from time to time (the "REGISTER"). The entries in
the Register shall be prima facie evidence of amounts owing, and the Borrower,
the Administrative Agent and the Lenders may treat each Person whose name is
recorded in the Register pursuant to the terms hereof as a Lender hereunder for
all purposes of this Credit Agreement, notwithstanding notice to

<Page>

                                      -71-

the contrary. The Register shall be available for inspection by the Borrower and
any Lender, at any reasonable time and from time to time upon reasonable prior
notice.

     15.4. PARTICIPATIONS. Any Lender may at any time, without the consent of,
or notice to, the Borrower or the Administrative Agent, sell participations to
any Person (other than a natural person) (each, a "PARTICIPANT") in all or a
portion of such Lender's rights and/or obligations under this Credit Agreement
(including all or a portion of its Commitment and/or the Revolving Credit Loans
owing to it); PROVIDED that (a) such Lender's obligations under this Credit
Agreement shall remain unchanged, (b) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations
and (c) the Borrower, the Administrative Agent and the other Lenders shall
continue to deal solely and directly with such Lender in connection with such
Lender's rights and obligations under this Credit Agreement. Any agreement or
instrument pursuant to which a Lender sells such a participation shall provide
that such Lender shall retain the sole right to enforce this Credit Agreement
and to approve any amendment, modification or waiver of any provision of this
Credit Agreement; PROVIDED that such agreement or instrument may provide that
such Lender will not, without the consent of the Participant, agree to any
amendment, modification or waiver that would reduce the principal of or the
interest rate on any Revolving Credit Loans, extend the term or increase the
amount of the Commitment of such Lender as it relates to such Participant,
reduce the amount of any Commitment Fee or Letter of Credit Fees to which such
Participant is entitled or extend any regularly scheduled payment date for
principal or interest. To the extent permitted by law, each Participant also
shall be entitled to the benefits of Section 16.1 as though it were a Lender,
provided such Participant agrees to be subject to Section 16.1 as though it were
a Lender.

     15.5. MISCELLANEOUS ASSIGNMENT PROVISIONS. A Lender may at any time grant a
security interest in all or any portion of its rights under this Credit
Agreement to secure obligations of such Lender, including without limitation (a)
any pledge or assignment to secure obligations to any of the twelve Federal
Reserve Banks organized under Section 4 of the Federal Reserve Act, 12 U.S.C.
Section 341 and (b) with respect to any Lender that is a Fund, to any lender or
any trustee for, or any other representative of, holders of obligations owed or
securities issued by such Fund as security for such obligations or securities or
any institutional custodian for such Fund or for such lender; PROVIDED that no
such grant shall release such Lender from any of its obligations hereunder,
provide any voting rights hereunder to the secured party thereof, substitute any
such secured party for such Lender as a party hereto or affect any rights or
obligations of the Borrower or Administrative Agent hereunder.

     15.6. ASSIGNEE OR PARTICIPANT AFFILIATED WITH THE BORROWER. If any assignee
Lender is an Affiliate of the Borrower, then any such assignee Lender shall have
no right to vote as a Lender hereunder or under any of the other Loan Documents
for purposes of granting consents or waivers or for purposes of agreeing to
amendments or other modifications to any of the Loan Documents or for purposes
of making requests to the Administrative Agent pursuant to Section 13.1 or
Section 13.2, and the determination of the Required Lenders shall for all
purposes of this Credit Agreement and the other Loan Documents

<Page>

                                      -72-

be made without regard to such assignee Lender's interest in any of the
Revolving Credit Loans or Reimbursement Obligations. If any Lender sells a
participating interest in any of the Revolving Credit Loans or Reimbursement
Obligations to a Participant, and such Participant is the Borrower or an
Affiliate of the Borrower, then such transferor Lender shall promptly notify the
Administrative Agent of the sale of such participation. A transferor Lender
shall have no right to vote as a Lender hereunder or under any of the other Loan
Documents for purposes of granting consents or waivers or for purposes of
agreeing to amendments or modifications to any of the Loan Documents or for
purposes of making requests to the Administrative Agent pursuant to Section 13.1
or Section 13.2 to the extent that such participation is beneficially owned by
the Borrower or any Affiliate of the Borrower, and the determination of the
Required Lenders shall for all purposes of this Credit Agreement and the other
Loan Documents be made without regard to the interest of such transferor Lender
in the Revolving Credit Loans or Reimbursement Obligations to the extent of such
participation.

     15.7. NEW REVOLVING CREDIT NOTES. Upon its receipt of an Assignment and
Acceptance executed by the parties to such assignment, together with each
Revolving Credit Note subject to such assignment, the Administrative Agent shall
(a) record the information contained therein in the Register, and (b) give
prompt notice thereof to the Borrower and the Lenders (other than the assigning
Lender). Within five (5) Business Days after receipt of such notice, the
Borrower, at its own expense, shall execute and deliver to the Administrative
Agent, in exchange for each surrendered Revolving Credit Note, a new Revolving
Credit Note to the order of such Assignee in an amount equal to the amount
assumed by such Assignee pursuant to such Assignment and Acceptance and, if the
assigning Lender has retained some portion of its obligations hereunder, a new
Revolving Credit Note to the order of the assigning Lender in an amount equal to
the amount retained by it hereunder. Such new Revolving Credit Notes shall
provide that they are replacements for the surrendered Revolving Credit Notes,
shall be in an aggregate principal amount equal to the aggregate principal
amount of the surrendered Revolving Credit Notes, shall be dated the effective
date of such Assignment and Acceptance and shall otherwise be in substantially
the form of the assigned Revolving Credit Notes. The surrendered Revolving
Credit Notes shall be cancelled and returned to the Borrower.

     15.8. SPECIAL PURPOSE FUNDING VEHICLE. Notwithstanding anything to the
contrary contained in this Section 15, any Lender (a "GRANTING LENDER") may
grant to a special purpose funding vehicle (an "SPC") of such Granting Lender,
identified as such in writing from time to time delivered by the Granting Lender
to the Administrative Agent and the Borrower, the option to provide to the
Borrower all or any part of any Revolving Credit Loan that such Granting Lender
would otherwise be obligated to make to the Borrower pursuant to this Credit
Agreement, PROVIDED that (a) nothing herein shall constitute a commitment to
make any Revolving Credit Loan by any SPC, (b) the Granting Bank's obligations
under this Credit Agreement shall remain unchanged, (c) the Granting Lender
should retain the sole right to enforce this Credit Agreement and to approve any
amendment, modification or waiver of any provision of this Credit Agreement and
(d) if an SPC elects not to exercise such option or otherwise fails to

<Page>

                                      -73-

provide all or any part of such Revolving Credit Loan, the Granting Lender shall
be obligated to make such Revolving Credit Loan pursuant to the terms hereof.
The making of a Revolving Credit Loan by an SPC hereunder shall utilize the
Commitment of the Granting Lender to the same extent, and as if, such Revolving
Credit Loan were made by the Granting Lender. Each party hereto hereby agrees
that no SPC shall be liable for any expense reimbursement, indemnity or similar
payment obligation under this Credit Agreement (all liability for which shall
remain with the Granting Lender). In furtherance of the foregoing, each party
hereto hereby agrees (which agreement shall survive the termination of this
Credit Agreement) that, prior to the date that is one year and one day after the
later of (i) the payment in full of all outstanding senior indebtedness of any
SPC and (ii) the Revolving Credit Loan Maturity Date, it will not institute
against, or join any other person in instituting against, such SPC any
bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings
or similar proceedings under the laws of the United States of America or any
State thereof. In addition, notwithstanding anything to the contrary contained
in this Section 16.9, any SPC may (A) with notice to, but (except as specified
below) without the prior written consent of, the Borrower or the Administrative
Agent and without paying any processing fee therefor, assign all or a portion of
its interests in any Revolving Credit Loans to its Granting Lender or to any
financial institutions (consented to by the Administrative Agent and, so long as
no Default or Event of Default has occurred and is continuing, the Borrower,
which consents shall not be unreasonably withheld or delayed) providing
liquidity and/or credit facilities to or for the account of such SPC to fund the
Revolving Credit Loans made by such SPC or to support the securities (if any)
issued by such SPC to fund such Revolving Credit Loans and (B) disclose on a
confidential basis any non-public information relating to its Revolving Credit
Loans (other than financial statements referred to in Sections 7.4 or 8.4) to
any rating agency, commercial paper dealer or provider of a surety, guarantee or
credit or liquidity enhancement to such SPC. In no event shall the Borrower be
obligated to pay to an SPC that has made a Revolving Credit Loan any greater
amount than the Borrower would have been obligated to pay under this Agreement
if the Granting Lender had made such Revolving Credit Loan. An amendment to this
Section 15.9 without the written consent of an SPC shall be ineffective insofar
as it alters the rights and obligations of such SPC.

                     16. PROVISIONS OF GENERAL APPLICATIONS.

     16.1. SETOFF. The Borrower hereby grants to the Administrative Agent and
each of the Lenders a continuing lien, security interest and right of setoff as
security for all liabilities and obligations to the Administrative Agent and
each Lender, whether now existing or hereafter arising, upon and against all
deposits, credits, collateral and property, now or hereafter in the possession,
custody, safekeeping or control of the Administrative Agent or such Lender or
any Lender Affiliate and their successors and assigns or in transit to any of
them. Regardless of the adequacy of any collateral, if any of the Obligations
are due and payable and have not been paid or any Event of Default shall have
occurred, any deposits or other sums credited by or due from any of the Lenders
to the Borrower and any securities or other property of the Borrower in the
possession of such Lender may be applied to or set off by such Lender against
the

<Page>

                                      -74-

payment of Obligations and any and all other liabilities, direct, or indirect,
absolute or contingent, due or to become due, now existing or hereafter arising,
of the Borrower to such Lender. ANY AND ALL RIGHTS TO REQUIRE ANY LENDER TO
EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH
SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO
SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF THE BORROWER ARE HEREBY KNOWINGLY,
VOLUNTARILY AND IRREVOCABLY WAIVED. Each of the Lenders agree with each other
Lender that (a) if an amount to be set off is to be applied to Indebtedness of
the Borrower to such Lender, other than Indebtedness evidenced by the Revolving
Credit Notes held by such Lender or constituting Reimbursement Obligations owed
to such Lender, such amount shall be applied ratably to such other Indebtedness
and to the Indebtedness evidenced by all such Revolving Credit Notes held by
such Lender or constituting Reimbursement Obligations owed to such Lender, and
(b) if such Lender shall receive from the Borrower, whether by voluntary
payment, exercise of the right of setoff, counterclaim, cross action,
enforcement of the claim evidenced by the Revolving Credit Notes held by, or
constituting Reimbursement Obligations owed to, such Lender by proceedings
against the Borrower at law or in equity or by proof thereof in bankruptcy,
reorganization, liquidation, receivership or similar proceedings, or otherwise,
and shall retain and apply to the payment of the Revolving Credit Note or
Revolving Credit Notes held by, or Reimbursement Obligations owed to, such
Lender any amount in excess of its ratable portion of the payments received by
all of the Lenders with respect to the Revolving Credit Notes held by, and
Reimbursement Obligations owed to, all of the Lenders, such Lender will make
such disposition and arrangements with the other Lenders with respect to such
excess, either by way of distribution, PRO TANTO assignment of claims,
subrogation or otherwise as shall result in each Lender receiving in respect of
the Revolving Credit Notes held by it or Reimbursement Obligations owed it, its
proportionate payment as contemplated by this Credit Agreement; PROVIDED that if
all or any part of such excess payment is thereafter recovered from such Lender,
such disposition and arrangements shall be rescinded and the amount restored to
the extent of such recovery, but without interest.

     16.2. EXPENSES. The Borrower agrees to pay (a) the reasonable costs of the
Administrative Agent (including the Administrative Agent's Special Counsel) of
producing and reproducing this Credit Agreement, the other Loan Documents and
the other agreements and instruments mentioned herein, (b) without duplication
of amounts payable pursuant to Section 5.3 hereof, any taxes (including any
interest and penalties in respect thereto) payable by the Administrative Agent
or any of the Lenders (other than taxes based upon the Administrative Agent's or
any Lender's net income) on or with respect to the transactions contemplated by
this Credit Agreement (the Borrower hereby agreeing to indemnify the
Administrative Agent and each Lender with respect thereto), (c) the reasonable
and documented fees, expenses and disbursements of the Administrative Agent's
Special Counsel or any local counsel to the Administrative Agent incurred in
connection with the preparation, syndication, administration or interpretation
of the Loan Documents and other instruments mentioned herein, each closing
hereunder, any amendments, modifications, approvals, consents or waivers

<Page>

                                      -75-

hereto or hereunder, or the cancellation of any Loan Document upon payment in
full in cash of all of the Obligations or pursuant to any terms of such Loan
Document for providing for such cancellation, (d) the fees, expenses and
disbursements of the Administrative Agent or any of its affiliates incurred by
the Administrative Agent or such affiliate in connection with the preparation,
syndication, administration or interpretation of the Loan Documents and other
instruments mentioned herein, (e) all reasonable and documented out-of-pocket
expenses (including without limitation reasonable attorneys' fees and costs, and
reasonable consulting, accounting, appraisal, investment banking and similar
professional fees and charges) incurred by any Lender or the Administrative
Agent in connection with (i) the enforcement of or preservation of rights under
any of the Loan Documents against the Borrower or any of its Subsidiaries or the
administration thereof after the occurrence of a Default or Event of Default and
(ii) any litigation, proceeding or dispute whether arising hereunder or
otherwise, in any way related to any Lender's or the Administrative Agent's
relationship with the Borrower or any of its Subsidiaries and (f) all reasonable
fees, expenses and disbursements of the Administrative Agent incurred in
connection with UCC searches. The covenants contained in this Section 16.2 shall
survive payment or satisfaction in full of all other obligations.

     16.3. INDEMNIFICATION. The Borrower agrees to indemnify and hold harmless
the Administrative Agent, its affiliates and the Lenders from and against any
and all claims, actions and suits whether groundless or otherwise, and from and
against any and all liabilities, losses, damages and expenses of every nature
and character arising out of this Credit Agreement or any of the other Loan
Documents or the transactions contemplated hereby including, without limitation,
(a) any actual or proposed use by the Borrower or any of its Subsidiaries of the
proceeds of any of the Revolving Credit Loans or Letters of Credit, (b) the
reversal or withdrawal of any provisional credits granted by the Administrative
Agent upon the transfer of funds from lock box, bank agency, concentration
accounts or otherwise under any cash management arrangements with the Borrower
or any Subsidiary or in connection with the provisional honoring of funds
transfers, checks or other items, (c) the Borrower or any of its Subsidiaries
entering into or performing this Credit Agreement or any of the other Loan
Documents or (d) with respect to the Borrower and its Subsidiaries and their
respective properties and assets, the violation of any Environmental Law, the
presence, disposal, escape, seepage, leakage, spillage, discharge, emission,

death, personal injury or damage to property), in each case including, without
limitation, the reasonable and documented fees and disbursements of incurred in
connection with any such investigation, litigation or other proceeding, except
to the extent that any of the foregoing are directly caused by the gross
negligence or willful misconduct of the otherwise indemnified party. In
litigation, or the preparation therefor, the Lenders and the Administrative
Agent and its affiliates shall be entitled to select their own counsel and, in
addition to the foregoing indemnity, the Borrower agrees to pay promptly the
reasonable and documented fees and expenses of such counsel. If, and to the

                                      -76-

unenforceable for any reason, the Borrower hereby agrees to make the maximum

permissible under applicable law. The covenants contained in this Section 16.3
shall survive payment or satisfaction in full of all other Obligations.

     16.4. TREATMENT OF CERTAIN CONFIDENTIAL INFORMATION.

            16.4.1. CONFIDENTIALITY. Each of the Lenders and the Administrative
     Agent agrees, on behalf of itself and each of its affiliates, directors,
     officers, employees and representatives, to use reasonable precautions to
     keep confidential, in accordance with their customary procedures for
     handling confidential information of the same nature and in accordance with
     safe and sound banking practices, any non-public information supplied to it
     by the Borrower or any of its Subsidiaries pursuant to this Credit
     Agreement that is identified by such Person as being confidential at the
     time the same is delivered to the Lenders or the Administrative Agent,
     PROVIDED that nothing herein shall limit the disclosure of any such
     information (a) after such information shall have become public other than
     through a violation of this Section 16.4, or becomes available to any of
     the Lenders or the Administrative Agent on a nonconfidential basis from a
     source other than the Borrower, (b) to the extent required by statute,
     rule, regulation or judicial process, (c) to counsel for any of the Lenders
     or the Administrative Agent, (d) to bank examiners or any other regulatory
     authority having jurisdiction over any Lender or the Administrative Agent,
     or to auditors or accountants, (e) to the Administrative Agent or any
     Lender, (f) in connection with any litigation to which any one or more of
     the Lenders, the Administrative Agent or any Financial Affiliate is a
     party, or in connection with the enforcement of rights or remedies
     hereunder or under any other Loan Document, (g) to a Lender Affiliate or a
     Subsidiary or affiliate of the Administrative Agent in connection with this
     Credit Agreement so long as such Person is bound by the provisions of this
     Section 16.4, (h) to any actual or prospective assignee or participant or
     any actual or prospective counterparty (or its advisors) to any swap or
     derivative transactions referenced to credit or other risks or events
     arising under this Credit Agreement or any other Loan Document so long as
     such assignee, participant or counterparty, as the case may be, agrees to
     be bound by the provisions of Section 16.4 or (i) with the consent of the
     Borrower. Moreover, each of the Administrative Agent and the Lenders (and
     their respective Affiliates) is hereby expressly permitted by the Borrower
     to refer to any of the Borrower and its Subsidiaries in connection with any
     advertising, promotion or marketing undertaken by the Administrative Agent,
     such Lender or such Affiliate and, for such purpose, the Administrative
     Agent, such Lender or such Affiliate may utilize any trade name, trademark,
     logo or other distinctive symbol associated with the Borrower or any of its
     Subsidiaries or any of their businesses.

            16.4.2. PRIOR NOTIFICATION. Unless specifically prohibited by
     applicable law or court order, each of the Lenders and the Administrative
     Agent shall, prior to disclosure thereof, notify the Borrower of any
     request for disclosure of any such non-public information by any
     governmental agency or representative

<Page>

                                      -77-

     thereof (other than any such request in connection with an examination of
     the financial condition of such Lender by such governmental agency) or
     pursuant to legal process.

            16.4.3. OTHER. In no event shall any Lender or the Administrative
     Agent be obligated or required to return any materials furnished to it or
     any Financial Affiliate by the Borrower or any of its Subsidiaries. The
     obligations of each Lender under this Section 16.4 shall supersede and
     replace the obligations of such Lender under any confidentiality letter in
     respect of this financing signed and delivered by such Lender to the
     Borrower prior to the date hereof and shall be binding upon any assignee
     of, or purchaser of any participation in, any interest in any of the
     Revolving Credit Loans or Reimbursement Obligations from any Lender.

     16.5. SURVIVAL OF COVENANTS, ETC. All covenants, agreements,
representations and warranties made herein, in the Revolving Credit Notes, in
any of the other Loan Documents or in any documents or other papers delivered by
or on behalf of the Borrower or any of its Subsidiaries pursuant hereto shall be
deemed to have been relied upon by the Lenders and the Administrative Agent,

and shall survive the making by the Lenders of any of the Revolving Credit Loans
and the issuance, extension or renewal of any Letters of Credit, as herein
contemplated, and shall continue in full force and effect so long as any Letter
of Credit or any amount due under this Credit Agreement or the Revolving Credit
Notes or any of the other Loan Documents remains outstanding or any Lender has
any obligation to make any Revolving Credit Loans or the Administrative Agent
has any obligation to issue, extend or renew any Letter of Credit, and for such
further time as may be otherwise expressly specified in this Credit Agreement.
All statements contained in any certificate or other paper delivered to any
Lender or the Administrative Agent at any time by or on behalf of the Borrower
or any of its Subsidiaries pursuant hereto or in connection with the

DEALINGS, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY,
INCLUDING ANY COURSE OF CONDUCT, COURSE OF DEALINGS, STATEMENTS OR ACTIONS OF
THE ADMINISTRATIVE AGENT OR ANY LENDER RELATING TO THE ADMINISTRATION OF THE
REVOLVING CREDIT LOANS OR ENFORCEMENT OF THE LOAN DOCUMENTS AND AGREES THAT IT
WILL NOT SEEK TO CONSOLIDATE ANY SUCH ACTION WITH ANY OTHER ACTION IN WHICH A
JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED. Except as prohibited by law, the
Borrower hereby waives any right it may have to claim or recover in any
litigation referred to in the preceding sentence any special, exemplary,
punitive or consequential damages or any damages other than, or in addition to,
actual damages. The Borrower (a) certifies that no representative, agent or
attorney of any Lender or the Administrative Agent has represented, expressly or
otherwise, that such Lender or the Administrative Agent would not, in the event
of litigation, seek to enforce the foregoing waivers and (b) acknowledges that
the Administrative Agent and the Lenders have been induced to enter into this
Credit Agreement, the other Loan Documents to which it is a party by, among
other things, the waivers and certifications contained herein.

     16.12. CONSENTS, AMENDMENTS, WAIVERS, ETC. Any consent or approval required
or permitted by this Credit Agreement to be given by the Lenders may be given,
and any term of this Credit Agreement, the other Loan Documents or any other
instrument related hereto or mentioned herein may be amended, and the
performance or observance by the Borrower or any of its Subsidiaries of any
terms of this Credit Agreement, the other Loan Documents or such other
instrument or the continuance of any Default or Event of Default may be waived
(either generally or in a particular instance and either retroactively or
prospectively) with, but only with, the written consent of the Borrower and the
written consent of the Required Lenders. Notwithstanding the foregoing, no
amendment, modification or waiver shall:

            (a) without the written consent of the Borrower and each Lender
     directly affected thereby:

                    (i) reduce or forgive the principal amount of any Revolving
            Credit Loans or Reimbursement Obligations, or reduce the rate of
            interest on the Revolving Credit Notes or the amount of the
            Commitment Fee or Letter

<Page>

                                      -80-

            of Credit Fees (other than interest accruing pursuant to Section
            5.11.2 following the effective date of any waiver by the Required
            Lenders of the Default or Event of Default relating thereto, with
            the Required Lenders being permitted to reduce or forgive any such
            interest from the first day such interest accrued);

                    (ii) increase the amount of such Lender's Commitment or
            extend the expiration date of such Lender's Commitment;

                    (iii) postpone or extend the Revolving Credit Loan Maturity
            Date or any other regularly scheduled dates for payments of
            principal of, or interest on, the Revolving Credit Loans or
            Reimbursement Obligations or any Fees or other amounts payable to
            such Lender (it being understood that (A) a waiver of the
            application of the default rate of interest pursuant to Section
            5.11.2 (including a waiver retroactive to the date such interest
            began accruing), and (B) any vote to rescind any acceleration made
            pursuant to Section 13.1 of amounts owing with respect to the
            Revolving Credit Loans and other Obligations shall require only the
            approval of the Required Lenders); and

                    (iv) other than pursuant to a transaction permitted by the
            terms of this Credit Agreement (including, without limitation, the
            sale of a Guarantor), release all or substantially all of the
            Guarantors from their guaranty obligations under the Guarantees;

            (b) without the written consent of all of the Lenders, amend or
     waive this Section 16.12 or the definition of Required Lenders (it being
     understood that the addition of one or more additional credit facilities,
     the allowance of the credit extensions, interest and fees thereunder to
     share ratably or on a subordinated basis with the Revolving Credit Loans,
     Letters of Credit, interest and Fees in the benefits of the Loan Documents
     and the inclusion of the holders of such facilities in the determination of
     Required Lenders shall require only the approval of the Required Lenders);

            (c) without the written consent of the Administrative Agent, amend
     or waive Section 14, the amount or time of payment of the Administrative
     Agent's Fee or any Letter of Credit Fees payable for the Administrative
     Agent's account or any other provision applicable to the Administrative
     Agent.

No waiver shall extend to or affect any obligation not expressly waived or
impair any right consequent thereon. No course of dealing or delay or omission
on the part of the Administrative Agent or any Lender in exercising any right
shall operate as a waiver thereof or otherwise be prejudicial thereto. No notice
to or demand upon the Borrower shall entitle the Borrower to other or further
notice or demand in similar or other circumstances.

                forth in Section 1.2 hereof, unless sooner terminated as
                hereinafter provided, and without any right of renewal or
                extension, except as expressly set forth in this Lease. After
                the Commencement Date, upon the request of either party,
                Landlord and Tenant shall enter unto an instrument confirming
                the Commencement Date and the expiration date of the Lease.

        (b)     As used herein the following terms shall have the following
                meanings:

                For the purposes of this Lease, a "Tenant Delay" shall mean any
                actual delay in the completion of Landlord's Work caused by a
                Tenant Change Order (as hereinafter defined) or any act or
                negligence of Tenant or its agents, employees, contractors or
                invitees or any failure by Tenant to act when Tenant has a duty
                so to act under the law or under the terms of this Lease,
                including, without limitation, (i) any failure by Tenant to
                deliver to Landlord any draft, revised or final versions of
                Tenant's Plans or to take any other action required of Tenant
                under this Lease within the period specified in this Lease, (ii)
                in instances for which the Lease specifies no period in which
                Tenant shall act, any failure by Tenant to respond to any
                reasonable request for information relating to Tenant's Work or
                otherwise to cooperate reasonably with Landlord, within a
                reasonable time after receiving from Landlord a written request
                for such information or cooperation.

                For the purposes of this Lease, a "Landlord Delay" shall mean
                any actual delay in the completion or commencement of the Tenant
                Work caused by any act or negligence of Landlord or its agents,
                employees, or contractors or any failure by Landlord to act when
                Landlord has a duty so to act under the terms of this Lease,
                including, without limitation, (i) any failure by Landlord to
                deliver to Tenant any draft, revised or final versions of plans
                to be prepared by or at the direction of Landlord hereunder or
                to take any

                                       -3-
<Page>

                other action required of Landlord under this Lease within the
                periods specified in this Lease, (ii) in instances for which
                this Lease specifies no period in which Landlord shall act, any
                failure by Landlord to respond to any reasonable request for
                information relating to Tenant's Work or otherwise to cooperate
                reasonably with Tenant, within a reasonable time after receiving
                from Tenant a written request for such information or
                cooperation, or (iii) any failure by Landlord to complete the
                Landlord's Work by the Target Date (as hereinafter defined).

                In the event that either party claims that the other has caused
                a Landlord Delay or a Tenant Delay, as applicable, the parties
                shall continue to perform their obligations hereunder in a
                manner so as to avoid any further delay. Landlord and Tenant
                each agree to promptly notify each other of any delay claimed by
                it against the other, and to notify each other in advance of any
                reasonably foreseeable delay, and the parties shall meet as soon
                as reasonably possible to discuss such delay claim, or such
                foreseeable delay claim, as applicable, but in no event shall
                the failure to reach agreement on such delay excuse either party
                from performing hereunder and waive such party's right to such
                delay claim.

                For purposes of this Lease, "Landlord's Force Majeure" shall
                mean any actual delay due to governmental regulations, unusual
                scarcity of or inability to obtain labor or materials (despite
                the exercise of reasonable efforts to obtain the same), labor
                difficulties fire or casualty or other causes reasonably beyond
                Landlord's control.

                For the purposes of this Lease, "Tenant's Force Majeure" shall
                mean any actual delay due to governmental regulation, unusual
                scarcity of or inability to obtain labor or materials (despite
                the exercise of reasonable efforts to obtain the same), labor
                difficulties, fire or casualty or other causes reasonably beyond
                the Tenant's control.

                Each party shall provide the other with written notice as
                promptly as possible after the occurrence of a claimed Force
                Majeure event hereunder and of the expected duration of the
                anticipated delay, and shall also notify the other as soon as
                such first party's Force Majeure event has ended, and shall use
                all reasonable efforts to cure the Force Majeure event.

        (c)     Subject to Tenant Delay and Landlord's Force Majeure, Landlord
                shall use reasonable speed and diligence in the construction of
                the Building and shall use its best efforts "to deliver" the
                Building and Premises to Tenant for its occupancy on or before
                August 1, 2002 (the "Target Date"). The failure "to deliver" the
                Premises and Building to Tenant for its occupancy by the Target
                Date shall in no way affect the validity of this Lease or the

                                       -4-
<Page>

                obligations of Tenant hereunder nor shall the same be construed
                in any way to extend the term of this Lease. Notwithstanding the
                foregoing, if the Premises and Building shall have not been
                delivered to Tenant within the meaning of Section 6.1 hereof
                within thirty (30) days after the Target Date, then except as
                expressly provided herein, Tenant shall not have any claim
                against Landlord and Landlord shall have no liability to Tenant,
                by reason thereof. If the Premises and the Building are not
                deemed delivered to Tenant under Section 6.1 hereof by the
                Target Date (extended to the extent of any Tenant Delay or
                Landlord's Force Majeure) then as Tenant's sole right and remedy
                in respect thereof, Tenant shall have, so long as Tenant is not
                in default under this Lease beyond the expiration of applicable
                notice and/or cure periods, a credit against the Fixed Rent
                first coming due hereunder in an amount equal to one (1) day's
                Fixed Rent for the Premises for each day after the Target Date
                (as so extended) until such delivery has been deemed made, but
                in any event such credit shall cease upon the date the Tenant
                shall first open for business in the Premises. (By way of
                example only, if the Premises and the Building are "delivered"
                on October 1, 2002, and the Target Date was August 1, 2002,
                then, following the Commencement Date, Tenant shall be entitled
                to a credit equal to the daily Fixed Rent rate for the Premises
                multiplied by 31, which amount Tenant may apply to the Fixed
                Rent due after the Commencement Date until the balance of said
                credit is equal to zero.)

                If the Premises are not deemed delivered to Tenant under Section
                6.1 hereof by August 1, 2003, Tenant shall have the right to
                terminate this Lease by written notice to Landlord given before
                the date of such delivery. If the Landlord having used
                reasonable efforts to deliver the Premises is unable to deliver
                the Premises by December 31, 2003 Landlord shall have the right
                to terminate this Lease by written notice to Tenant given before
                the date of such delivery.

2.2     APPURTENANT RIGHTS AND RESERVATIONS. Tenant shall have, as appurtenant
        to the Premises, the nonexclusive right to use and to permit its
        invitees to use in common with others, public or common lobbies, if any,
        elevators, hallways, stairways, loading docks and loading areas, service
        lifts, sanitary facilities, pipes, ducts, conduits, shafts, wires and
        appurtenant equipment providing electricity, telephone, water, sewer,
        telecommunications and other utilities to the Premises and equipment to
        the roof and all other common areas, if any, located in the Building and
        all sidewalks, access roads and driveways, located on the Lot and
        serving the Building (the "Common Areas"), but such rights shall always
        be subject to reasonable rules and regulations from time to time
        established by Landlord by suitable notice and to the right of Landlord
        to designate and change from time to time areas and facilities so to be
        used, provided that any such change shall not materially interfere with
        Tenant's use of, or access to, the Premises. All elevators serving Wing
        One and all parking levels of the

                                       -5-
<Page>

        Garage that serve Wing One shall not be deemed part of the Premises, but
        shall be for the exclusive use of Tenant and its agents, employees and
        invitees. Landlord acknowledges that of the elevators in Wing One one
        serves all floors of the Garage and the first floor of Wing One above
        the Garage and the other two elevators serve the top floor of the Garage
        and all floors of Wing One above the Garage. The lobby of Wing One shall
        be deemed part of the Premises. At all times during the Term, Landlord
        shall make available at least one (1) elevator serving the portion of
        the Premises in Wing Two and the top level of the Garage, which elevator
        shall be for the exclusive use of Tenant and its agents, employees and
        invitees.

        Excepted and excluded from the Premises are the roof or ceiling, the
        structural floor and all perimeter walls of the Premises, except in each
        case the inner surfaces thereof, but the entry doors to the Premises are
        not excluded from the Premises and are a part thereof for all purposes;
        and Tenant agrees that Landlord shall have the right to place in the
        Premises (but in such manner as to reduce to a minimum interference with
        Tenant's use of the Premises) utility lines, pipes and the like to serve
        premises other than the Premises, and to replace, maintain and repair
        such utility lines, pipes and the like, in, over and upon the Premises.
        Notwithstanding the foregoing, Tenant's prior consent, which consent
        Tenant shall not unreasonably withhold or delay, shall be required with
        respect to any exhaust systems to be located within the Premises and
        which are to serve restaurants located outside of the Premises. Tenant
        shall have the right to place on the roof of Wing One and Wing Two,
        supplementary HVAC equipment, satellite antennae and satellite dishes
        which are to serve the Premises and are not to be utilized by any other
        person other than the occupants of the Premises and are to be placed on
        the roof in such location as shall be reasonably approved by Landlord;
        provided, however, that Tenant shall have Tenant's pro-rata share of all
        the roof space on Wing One and Wing Two that is made available or used
        for antennae and satellite dishes or supplementary HVAC equipment for
        its exclusive use. Any other antennae or satellite dishes on said roof
        shall be installed thereon in such a manner so as not to interfere with
        the antennae or dishes of Tenant. All antennae and satellite dishes and
        supplementary HVAC equipment shall be installed so as to minimize the
        visibility of such antennae or dishes or supplementary HVAC equipment
        from outside the Building. All of such installation and maintenance of
        such antennae, dishes and supplementary HVAC equipment shall be
        performed by contractors reasonably approved by Landlord and in a manner
        so as not to void any roofing warranty and Tenant shall be responsible
        for any damage to the roof caused by the installation or maintenance of
        the same, and at the end of the term of the Lease, the Tenant shall
        remove all of such antennae, dishes and supplementary HVAC equipment
        from the roof and shall repair all damage caused by the installation or
        removal of the same.

        Subject to reasonable rules and regulations imposed from time to time by
        Landlord, the Building shall be open and access to the Premises shall be
        freely

                                       -6-
<Page>

        available, subject to interruption due to causes beyond Landlord's
        reasonable control, at all times. Tenant acknowledges that, in all
        events, Tenant is responsible for providing security to the Premises and
        its own personnel, and Tenant shall indemnify, defend with counsel
        reasonably acceptable to Landlord, and save Landlord harmless from any
        claim for injury to person or damage to property asserted by any
        personnel, employee, guest, invitee or agent of Tenant which injury or
        damage is suffered or occurs in the Premises by reason of the act of an
        intruder or any other person in or the Premises.

2.3     PARKING RIGHTS. During the term hereof, Tenant shall have the right to
        the daytime use (i.e. no later than 7 PM on any day) of 115 parking
        spaces ("daytime parking") located within the garage serving the
        Building. Such spaces may be on an assigned or unassigned basis at
        Landlord's discretion and Tenant shall comply with all reasonable rules
        and regulations which Landlord may impose from time to time for the
        regulation of such parking (such rules and regulations shall provide,
        INTER ALIA, that no towing can be made without reasonable advance
        notice). In addition, without charge to Tenant, Tenant shall have the
        exclusive use of 75 parking spaces in the Garage at all times. The
        location of Tenant's daytime parking spaces and of such exclusive spaces
        shall be as provided in the Parking Plan set forth on Exhibit E hereto.
        Except as otherwise set forth in this paragraph, no parking shall be
        allowed to Tenant on an overnight basis nor shall the parking rates so
        allocated to Tenant be utilized by other than Tenant's officers or
        employees or assigns or sublessees or invitees, and Tenant shall have no
        right to assign or sublicense any of its parking rights hereunder except
        to a permitted assignee of this Lease or sublesee of the Premises or to
        a party providing business services to Tenant. The foregoing, however,
        shall not limit Tenant from reimbursement by its employees or officers
        for any or all of such charges. Landlord shall bear no liability in
        respect of any vehicles (or their contents) parked in such facility and
        Tenant waives all liability which Landlord may have in respect thereof,
        except to the extent the same results from Landlord's negligence or
        willful misconduct. As consideration for such daytime parking rights
        Tenant shall pay to Landlord an amount equal to the then market charge,
        as imposed by Landlord, for the daytime parking rights (the other
        seventy-five of such parking rights shall be without charge). Initially
        such charge shall be at the rate of $150 per parking right per month but
        shall be subject to change from time to time (but not more than once
        annually) by the Landlord. Such payment shall be considered to be
        Additional Rent under this Lease and Tenant's failure to pay the same
        shall be considered a failure in the payment of rent under this Lease.
        Such payment shall be due at the same time as the monthly payments of
        Fixed Rent in advance. In the event that during the Lease Term,
        additional area shall be added to the Premises so that the Rentable
        Floor Area of the Premises shall increase ("Expansion Space") then the
        number of parking spaces available to Tenant under this section shall be
        increased by two spaces for each 1,000 square feet of Rentable Floor
        Area in the Expansion Space, which spaces shall be considered to be
        daytime parking spaces for all purposes; provided, however, that such

                                       -7-
<Page>

        additional spaces shall be made available to Tenant only if, and to the
        extent, that Landlord has such spaces available and has not committed
        such spaces to other tenants or persons, but if the former tenant of the
        Expansion Space had any parking spaces for its use, such parking spaces
        shall be made available to Tenant. Whenever any other parking spaces
        within the Garage shall become available for monthly use by other than
        the tenants or occupants of the Building or their customers, Landlord
        shall notify Tenant thereof and of any terms for leasing of the same.
        The provisions of this Section 2.3 shall apply during the Original Lease
        Term and any extension thereof.

                                   ARTICLE III
                                      RENT

3.1     FIXED RENT. Tenant agrees to pay to Landlord at the Present Mailing
        Address of Landlord, or as directed by Landlord, without notice, demand,
        off-set or deduction (except as expressly permitted hereunder), on the
        Commencement Date and thereafter, monthly, in advance, on the first day
        of each and every calendar month during the Lease Term, a sum equal to
        the monthly Fixed Rent specified in Section 1.2 hereof; provided,
        however, that the first payment of monthly Fixed Rent coming due under
        this Lease shall be made on the first day of the second calendar month
        of the Term of this lease and shall be made for and with respect to the
        period of time from the Commencement Date of the term of this lease
        through the end of said calendar month.

        Fixed Rent for any partial month shall be paid by Tenant at such rate on
        a pro-rata basis (based on the per diem rate of Fixed Rent multiplied by
        the number of days in such partial month included in the Term) and, if
        the Lease Term commences on a day other than the first day of a calendar
        month, the first payment which Tenant shall make shall be a payment
        equal to a proportionate part of such monthly Fixed Rent for the partial
        month from the Commencement Date to the first day of the succeeding
        calendar month, and the monthly Fixed Rent for such succeeding calendar
        month.

                                   ARTICLE IV
                                 USE OF PREMISES

4.1     PERMITTED USE. Tenant agrees that the Premises shall be used and
        occupied by Tenant only for the purpose specified as the use thereof in
        Section 1.2 of this Lease, and for no other purpose or purposes.

        Tenant further agrees to conform to the following provisions during the
        entire Lease Term:

        (a)     Tenant shall cause all freight (including furniture, fixtures
                and equipment used by Tenant in the occupancy of the Premises)
                to be delivered to or

                                       -8-
<Page>

                removed from the Building and the Premises in such areas
                reasonably designated by Landlord therefor and in accordance
                with reasonable rules and regulations established by Landlord
                therefor, the hours for such delivery to be fixed so as not to
                violate the terms of the transportation access plan agreement
                ("TAPA") entered into by Landlord with the City of Boston;

        (b)     Subject to Legal Requirements and so long as Tenant leases at
                least 50% of the office portions of the Building Tenant shall
                have the exclusive right to install signage on the door of the
                Premises and on the exterior of the Building, above the ground
                floor, subject only to the exceptions set forth below. The
                parties acknowledge that Vitale and Caturano ("V&C") is a
                current tenant in Wing Two and that Landlord has obligated
                itself to provide certain signage rights in its lease to V&C.
                Tenant acknowledges that it has been informed by Landlord that
                V&C has the one time option to choose the location of its
                signage on the exterior of Wing Two as follows: (i) between the
                first and second floor; or (ii) between the second and third
                floor. Landlord shall use continuing reasonable efforts to cause
                V&C (or its successors, assigns or sublessees) to select option
                (i). Thereafter, V&C may install signage ("V&C Sign") only as
                set forth above, which signage may not be altered during the
                term of the V&C lease except to change the name to any permitted
                assignee or sublessee of all or substantially all of the V&C
                premises but any such changed sign shall be of a similar size
                and style and shall be in lieu of the V&C sign, and signage
                rights shall not transfer to any subtenant of less than
                substantially all of the V&C premises or licensee, or any other
                party that may acquire rights to use and occupy a portion of the
                premises currently leased by V&C. Upon the expiration or earlier
                termination of the V&C lease, the signage rights set forth above
                shall terminate and the V&C Sign shall be promptly removed by
                Landlord, at its sole cost and expense. Landlord represents that
                the V&C lease has a 10 year initial term with 2-5 year options
                of extension. The Landlord shall have the right to install on
                the exterior of the Building in the signage band serving the
                ground floor retail premises signage for the ground floor retail
                tenants. Tenant shall not place on the exterior of exterior
                walls (including both interior and exterior surfaces of windows
                and doors) or on any part of the Building outside the Premises,
                any sign, symbol, advertisement or the like visible to public
                view outside of the Premises except for a sign on the door of
                the Premises of the type commonly and customarily found in
                first-class office buildings for the purpose of identifying and
                locating the Premises and except for a sign located on the
                exterior of Wing One, the size and design of which sign shall
                always be subject to the prior approval of Landlord which shall
                not be unreasonably withheld or delayed and to compliance with
                all applicable law and regulations. Without Tenant's prior
                written approval signed by an executive officer of Tenant, no
                sign of any other tenant shall be located on the exterior of the
                Building above the

                                       -9-
<Page>

                ground floor level, except for the V&C sign as set forth above.
                Tenant will not install drapes, window blinds or other window
                coverings on exterior windows except for those reasonably
                approved by Landlord and in all events all such coverings shall
                be of a color reasonably approved by Landlord;

        (c)     Tenant shall not perform any act or any practice which injures
                the Premises, or any other part of the Building, or causes any
                offensive odors or loud noise, or constitutes a nuisance to any
                other tenant or tenants or occupants or other persons in the
                Building, or be detrimental to the reputation or appearance of
                the Building; Landlord shall impose a restriction to the
                substance of that set forth in this subsection (c) in leases of
                all other tenants in the Building and shall use reasonable
                efforts to enforce such restrictions, but Landlord shall have no
                liability to Tenant in respect of its failure to enforce such
                restriction.

        (d)     At Tenant's option, Landlord shall refer to Wing One of the
                Building as the "Keane Building" and shall not be entitled to
                change the name of Wing One during the Term and shall not name
                the Building or Wing Two after another tenant. Tenant shall not
                use the name of the Building directly or indirectly in
                connection with Tenant's business, except as a part of Tenant's
                address, and Landlord reserves the right to change the name of
                the Building at any time but in no event shall the name of the
                Building be changed to the name of any other tenant of the
                Building or any business organization so long as Tenant leases
                at least 35% of the office portion of the Building and no other
                tenant leases more space in the Building;

        (e)     The Tenant shall not use, handle, store, release or discharge
                hazardous materials, oil, or hazardous wastes in the Premises
                except for small amounts of cleaning materials and other
                materials normally used in office uses which might be deemed to
                be hazardous materials or hazardous waste under applicable law,
                provided that in its use, handling, storage, release and
                discharge thereof the Tenant shall comply with all applicable
                law and with the requirements of the manufacturers thereof;

        (f)     Within the Premises, Tenant shall comply with the Americans With
                Disabilities Act (42 U.S.C. Section 12101 et seq.) and the
                regulations and Accessibility Guidelines for Buildings and
                Facilities issued pursuant thereto (collectively the "ADA"), to
                the extent the same are applicable to the Premises; provided
                that Tenant shall not be required to so comply with the ADA to
                the extent that the Premises when delivered by Landlord to
                Tenant were not in compliance with the ADA or where compliance
                by Tenant is required as a result of any action by Landlord.

4.2     ALTERATIONS. After initial completion of any work to be done by Tenant
        as provided in Article VI, Tenant shall not alter or add to the
        Premises, except in accordance with written consent from Landlord, which
        Landlord agrees not unreasonably to withhold or delay as to alterations
        or additions which (i) are not visible from the exterior of the Premises
        and (ii) do not materially affect the structure or any mechanical,
        electrical or plumbing systems of the Building. Notwithstanding the
        foregoing, Landlord's prior written consent shall not be required with
        respect to any non-structural, interior alterations to the Premises
        which do not adversely affect the mechanical, electrical or plumbing
        systems of the Building and have a cost, in each instance, of less than
        $100,000, but Tenant shall notify Landlord as and when it makes any such
        alterations which are permitted without Landlord's prior consent.
        Tenant's work as described in Article VI and all other alterations,
        changes, additions and work ("Alterations") made by Tenant shall be made
        in accordance with all applicable laws, in a good and first-class
        workmanlike manner and in accordance with the reasonable requirements of
        Landlord's insurers and Tenant's insurers. Without limitation, said
        Tenant's work as described in Article VI and all other Alterations made
        by Tenant shall be performed in accordance with the provisions of this
        Article IV and of Article VI. Any contractor or other person undertaking
        any Alterations of the Premises on behalf of Tenant shall be covered by
        Commercial General Liability and Workmen's Compensation insurance with
        coverage limits reasonably acceptable to Landlord and evidence thereof
        shall be furnished to Landlord prior to the performance by such
        contractor or person of any work in respect of the Premises. Except for
        generators and HVAC supplemental equipment which Tenant has installed at
        its sole cost and expense on the roof of the Building to exclusively
        serve the Premises (such installation hereby is approved but shall be
        made in accordance with plans and specifications approved by Landlord
        such approval not to be unreasonably withheld or delayed, and in a
        manner so as not to void any roofing warranty and by contractors
        reasonably approved by Landlord, and at the end of the Term of the
        Lease, Tenant shall remove all of such equipment from the roof and shall
        repair all damage caused by the installation or removal of the same),
        all work performed by Tenant in the Premises shall remain therein and,
        at termination, shall be surrendered as a part thereof, except for
        Tenant's usual trade fixtures, furniture and equipment, installed prior
        to or during the Lease Term at Tenant's cost, which trade fixtures,
        furniture and equipment Tenant shall remove upon the termination of this
        Lease. Tenant agrees to repair any and all damage to the Premises
        resulting from the installation thereof or such removal or, if Landlord
        so elects, to pay Landlord for the cost of any such repairs forthwith
        after actual completion thereof and billing therefor.

        Landlord has given Tenant notice that on or about February 8, 2002 is
        (i) the date when Landlord plans to finish its construction of the roof
        and to install the rubberized roofing; and (ii) the date when Landlord
        plans to install the concrete filling on the roof.

                                    ARTICLE V
                            ASSIGNMENT AND SUBLETTING

5.1     PROHIBITION. Notwithstanding any other provisions of this Lease, Tenant
        covenants and agrees that it will not assign this Lease or sublet (which
        term, without limitation, shall include the granting of concessions,
        licenses, and the like) the whole or any part of the Premises without,
        in each instance, having first received the express written consent of
        Landlord, which consent the Landlord agrees not to unreasonably
        withhold, condition or delay, provided that the following conditions are
        satisfied, all in Landlord's reasonable judgment: (a) the proposed
        assignee or sublessee proposes office operations in the Premises which
        are consistent with the image and quality of the Building; (b) the
        proposed assignee or sublessee is not a governmental organization; (c)
        the proposed assignee or sublessee has the financial capacity necessary
        to carry out its obligations under this Lease or the sublease, as the
        case may be; (d) the operations proposed by the assignee or sublessee
        will not overload the Building's systems; and (e) any proposed
        subletting shall not result in a division of the Premises into more than
        two units per floor unless Tenant assumes in writing the cost and
        expense to restore the Premises upon the termination of this Lease.
        Landlord shall respond to any request for consent within thirty (30)
        days (ten (10) business days in the case of a subletting of one (1)
        floor or less), after receipt of Tenant's request for consent, and if
        such request contains a reminder in bold print of the timing for
        response, then if Landlord does not timely respond the consent shall be
        deemed granted.

        Any assignment of this Lease (which term shall include the subletting of
        the whole or any part of the Premises other than as permitted hereunder
        as set forth below) by Tenant without Landlord's express consent shall
        be invalid, void and of no force or effect. In any case where Landlord
        shall consent to such assignment or subletting, the Tenant named herein
        shall remain fully liable for the obligations of Tenant hereunder,
        including without limitation, the obligation to pay the Fixed Rent and
        other amounts provided under this Lease. Any such request shall set
        forth, in detail reasonably satisfactory to Landlord, the identification
        of the major business terms upon which proposed assignment or subletting
        is to be made, including, without limitation, the rent or any other
        consideration to be paid in respect thereto.

        It shall be a condition of the validity of any such assignment that the
        assignee agrees directly with Landlord, in form reasonably satisfactory
        to Landlord, to be bound by all the obligations of Tenant hereunder,
        including, without limitation, the obligation to pay Fixed Rent and
        other amounts provided for under this Lease and the covenant against
        further assignment and subletting, except as expressly permitted
        hereunder, but such assignment or subletting shall not relieve the
        Tenant named herein of any of the obligations of Tenant hereunder, and
        Tenant shall remain fully liable therefor. In no event, however, shall
        Tenant assign this

                                      -12-
<Page>

        Lease or sublet the whole or any part of the Premises to a proposed
        assignee or sublessee which has been judicially declared bankrupt or
        insolvent according to law, or with respect to which an assignment has
        been made of property for the benefit of creditors, or with respect to
        which a receiver, guardian, conservator, trustee in involuntary
        bankruptcy or similar officer has been appointed to take charge of all
        or any substantial part of the proposed assignee's or sublessee's
        property by a court of competent jurisdiction, or with respect to which
        a petition has been filed for reorganization under any provisions of the
        Bankruptcy Code now or hereafter enacted, or if a proposed assignee or
        sublessee has filed a petition for such reorganization, or for
        arrangements under any provisions of the Bankruptcy Code now or
        hereafter enacted and providing a plan for a debtor to settle, satisfy
        or extend the time for the payment of debt. Tenant shall, within thirty
        days after demand, reimburse Landlord for the reasonable out-of-pocket
        legal fees and expenses (not to exceed $500 in any one instance)
        incurred by Landlord in processing any request to assign this Lease or
        to sublet all or any portion of the Premises, whether or not Landlord
        agrees thereto, and if Tenant shall fail to reimburse Landlord, the same
        shall be a default in Tenant's monetary obligations under this Lease.

        Without limitation of the rights of Landlord hereunder in respect
        thereto, if there is any assignment of this Lease by Tenant for
        consideration or a subletting of the whole of the Premises by Tenant at
        a rent or other consideration which exceeds the rent payable hereunder
        by Tenant, or if there is a subletting of a portion of the Premises by
        Tenant at a rent in excess of the subleased portion's pro rata share of
        the rent payable hereunder by Tenant (which shall not include any
        consideration given for the use of furniture, telecommunications
        equipment or other equipment), then Tenant shall pay to Landlord, as
        additional rent, forthwith upon Tenant's receipt of the consideration
        (or the cash equivalent thereof) therefor, 50% of any such excess, after
        Tenant has recouped the reasonable out-of-pocket costs and expenses
        which Tenant has incurred in entering into such assignment or sublet.
        The provisions of this paragraph shall apply to each and every
        assignment of this Lease and each and every subletting of all or a
        portion of the Premises, except to a Permitted Transferee (as defined
        below), in each case on the terms and conditions set forth herein. For
        the purposes of this Section 5.1, the term "rent" shall mean all Fixed
        Rent, additional rent or other payments and/or consideration payable by
        one party to another for the use and occupancy of all or a portion of
        the Premises.

        The provisions of this Section 5.1 relating to the necessity of
        Landlord's prior consent shall not, however, be applicable to an
        assignment of this Lease by Tenant to (i) a subsidiary (for such period
        of time as the stock of such subsidiary continues to be owned by Tenant,
        it being agreed that except as hereinafter set forth the subsequent sale
        or transfer of fifty percent (50%) or more of the stock of such
        subsidiary shall be treated as if such sale or transfer were, for all
        purposes, an assignment of this Lease governed by the Provisions of this
        Section 5.1); or (ii) controlling corporation; or (iii) corporation
        under common control with

                                      -13-
<Page>

        Tenant (an "affiliate") (but if at any time such entity ceases to be an
        affiliate, then except as hereinafter set forth the same shall be
        treated as an assignment of this Lease governed by the provisions of
        this Section 5.1); or (iv) to an entity which is acquiring all of
        Tenant's assets whether through an acquisition of assets, merger, or
        consolidation (each such transferee herein a "Permitted Transferee");
        provided (and it shall be a condition of the validity of any such
        assignment) that such Permitted Transferee agree directly with Landlord
        to be bound by all of the obligations of Tenant hereunder, including,
        without limitation, the obligation to pay the rent and other amounts
        provided for under this Lease, the covenant to use the Premises only for
        the purposes specifically permitted under this Lease and the covenant
        against further assignment except as permitted herein; but such
        assignment shall not relieve Tenant herein named of any of its
        obligations hereunder, and Tenant shall remain fully liable therefor.
        Notwithstanding the foregoing, should Tenant enter into a sublease of a
        portion (being less than 50% of the floor area) of the Premises with a
        subsidiary or affiliate then the "spin off" of such subsidiary or
        affiliate through the sale of stock thereof to a third party or the
        merger or consolidation of such subsidiary or affiliate with such third
        party where such spin off is accomplished to further the business
        objectives of the Tenant and not to avoid the prohibition against
        subletting set forth herein shall be permitted without the necessity of
        the Landlord's consent, provided that (i) as herein set forth the Tenant
        shall remain obligated under this Lease notwithstanding such subletting
        and (ii) the sublessee shall agree directly with Landlord that its
        sublease is subject and subordinate to this Lease in all respects and
        that it will attorn to Landlord, at Landlord's request, should this
        Lease terminate for any reason.

                            DELIVERY OF PREMISES AND
                           RESPONSIBILITY FOR REPAIRS
                              CONDITION OF PREMISES

6.1     DELIVERY OF POSSESSION OF PREMISES.

        (a)     Subject to and in accordance with the terms and conditions of
                this Lease, Landlord shall, at its expense, commence and
                diligently prosecute to completion in a good and workmanlike
                manner in accordance with all applicable laws, rules,
                regulations, requirement, statutes, ordinances, by-laws and
                court decisions which are now or hereafter in force (the "Legal
                Requirements"): (i) the Building and other improvements
                associated therewith in accordance with Landlord's Plans and
                Specifications (as defined below); and (ii) all other
                improvements to be constructed on the Lot (including, without
                limitation, parking areas, roads, sidewalks, utility lines,
                lighting, fire safety systems and landscaping) necessary for the
                operation, use and maintenance of the Building for the purposes
                set forth herein. Landlord represents and warrants that to its
                knowledge as of the date hereof it has obtained all material
                federal, state and local permits and

                                      -14-
<Page>

                approvals necessary for the construction and operation of the
                Building except for a building permit and a conditional use
                permit under the Boston Zoning Code and (ii) once such a
                conditional use permit is obtained and no longer subject to
                appeal, the Use is permitted as of right under applicable zoning
                ordinances and under the Ground Lease.

        (b)     Following substantial completion of the Landlord's Work,
                Landlord shall cause its architect Add Inc. (the "Architect"),
                to measure the rentable floor area of the Building and the
                Premises in accordance with BOMA standards for a multi-tenant
                building, but in no event shall the loss factor in connection
                therewith exceed 12%, and to certify such area and the final
                usable floor area of the Building and Premises in writing to
                Landlord and Tenant and to furnish a copy of such
                certifications, along with sufficiently detailed back-up
                information include a breakdown of the architect's calculation
                and CAD Discs in a commercially standard format, to Tenant for
                confirmation by Tenant and Tenant's architect. If within ten
                (10) business days after Tenant has received from Landlord such
                certifications and backup information Tenant has neither
                approved such certifications in writing or given written
                objection to the same stating the reasons therefor, then
                Landlord may give Tenant notice reminding Tenant that Tenant has
                not approved or rejected the same and if within ten (10)
                business days thereafter Tenant still fails to act then the
                certifications shall be deemed confirmed and approved by Tenant.
                However, if Tenant timely objects to such certifications, then
                the measurement of the Rentable Floor Area of the Building and
                Premises shall be made by an independent third party AIA
                certified architect chosen jointly by the Architect and Tenant's
                architect and the costs of such third party architect shall be
                borne jointly by Landlord and Tenant. Following agreement by the
                parties on the measurements so made or its determination by
                arbitration as set forth above, such measurements shall then be
                the "Rentable Floor Area of the Building" and "Rentable Floor
                Area of the Premises" and shall be substituted in the definition
                of "Rentable Floor Area of the Building" and "Rentable Floor
                Area of the Premises" as set forth in Section 1.2 of this Lease,
                and that determination of Rentable Floor Area of the Premises
                shall then be used in computing and determining the annual Fixed
                Rent payable during the original Lease Term (as set forth under
                the definition of annual Fixed Rent in Section 1.2 hereof), the
                Tenant Allowance (as set forth in Section 6.3A hereof) and the
                other provisions of this Lease involving the Rentable Floor Area
                of the Building or the Premises. In addition, Landlord and
                Tenant shall promptly execute a written statement in recordable
                form setting forth the recomputed figures resulting from such
                determination.

        (c)     Landlord shall not, without Tenant's prior written consent not
                to be unreasonably withheld or delayed, make any changes to
                Landlord's Work

                                      -15-

                that would (i) cause a delay in the Target Date, (ii) reduce or
                otherwise materially adversely affect the nature, quality or
                capacity of the heating, ventilating, air-conditioning,
                plumbing, mechanical (including elevators), electrical,
                telephone, telecommunications and other utilities, services,
                systems and equipment serving the Premises, or (iii) require any
                substantial revision to Tenant's Approved Plans (as defined in
                Section 6.2 below) or otherwise materially affect the design of
                the Tenant's Work (as defined below).

        (d)     The Premises shall be conclusively deemed delivered to Tenant as
                soon as the initial work to be done by Landlord as set forth in
                Exhibit C hereto (the "Landlord's Work or "Landlord Work") has
                been substantially completed by Landlord (as defined in Section
                6.3B) or would have been so completed except for Tenant Delay.
                If any delay in such substantial completion is

                (i)     due to any change in the Landlord's Work requested by
                        Tenant (a "Tenant Change Order"); or

                (ii)    caused in whole or in part by another Tenant Delay

        then the Premises shall be deemed ready on the date the same would have
        been ready except for such delay caused by a Tenant Change Order or
        Tenant Delay.

        If as hereinabove provided the Premises are so deemed ready for Tenant's
        occupancy prior to the time they are actually ready for Tenant's
        occupancy, Tenant shall not (except with Landlord's consent) be entitled
        to take possession of the Premises for use as set forth herein until the
        Premises are in fact actually ready for such occupancy, notwithstanding
        the fact because the premises shall have as above stated been deemed
        ready for such occupancy that the Term hereof shall on that account have
        commenced..

6.2     PLANS AND SPECIFICATIONS. Annexed hereto as Exhibit C-1 is a matrix
        showing the elements of Landlord's Work and Tenant's Work. Landlord has
        prepared and delivered to Tenant Landlord's plans and specifications
        ("Landlord's Plans and Specifications") for Landlord's Work. The same
        have been approved by Tenant. All of Landlord's Work shall be performed
        in accordance with Landlord's Plans and Specifications. Tenant agrees to
        deliver to Landlord by April 1, 2002 schematic and design plans (herein
        called "Schematic Tenant Plans") for the work to be undertaken to
        prepare the Premises for Tenant's use and occupancy by Tenant (the
        "Tenant Work") for Landlord's review and approval which approval shall
        not be unreasonably withheld, conditioned or delayed. Landlord shall
        cooperate reasonably with Tenant and its architect in connection with
        the preparation of the Schematic Tenant Plans, including, without
        limitation, providing copies of the Landlord's Plans and Specifications
        and any other information relating to the Building and the Landlord's
        Work as Tenant or

                                      -16-
<Page>

        its architect may reasonably request and permitting Tenant or its
        architect reasonable access to the Building and the Lot to take
        measurements and to perform inspections.

        Any submittal to Landlord which is not responded to by Landlord in
        writing within fifteen (15) business days of receipt of the same (and
        with respect to any revised submittal, within five (5) business days of
        receipt of the same) shall be deemed approved provided that the
        submittal contains a statement at a prominent location and in bold type
        to the following effect: "If you do not respond to this submittal in
        writing within fifteen (15) business days [or five (5) business days, as
        applicable], this submittal shall be deemed approved." Tenant shall
        deliver to Landlord within the later of (i) April 1, 2002 or (ii) ninety
        (90) days after Landlord has approved Tenant's approved Schematic Tenant
        Plans, construction drawings (herein called "Initial Tenant Plans") for
        the Tenant Work for Landlord's review and approval, which approval shall
        not be unreasonably withheld, conditioned or delayed; provided, however,
        Landlord may not disapprove any matter that is consistent with Tenant's
        approved Schematic Tenant Plans. Landlord shall cooperate reasonably
        with Tenant and its architect in connection with the preparation of the
        Initial Tenant Plans, including, without limitation, providing such
        information as Tenant or its architect may reasonably request and
        permitting Tenant or its architect reasonable access to the Building and
        the Lot to take measurements and perform inspections.

        For the purposes of this Lease, "Tenant Approved Plans" shall mean the
        final version of the Initial Tenant Plans approved by Landlord.

        Tenant may, from time to time, submit to Landlord any material changes
        or additions to the Tenant's Approved Plans desired by Tenant, which
        changes or additions shall be subject to Landlord's approval, which
        shall not be unreasonably withheld, conditioned or delayed provided the
        same do not delay Landlord's Work or result in any increase to Landlord
        in cost, provided, however that in the case where the same do not delay
        Landlord's Work but do result in an increase to Landlord in cost then
        Landlord shall make the same provided that Tenant has agreed in writing
        with Landlord to pay all of such increased costs promptly upon billing
        therefor, in which case Tenant shall pay such costs to Landlord promptly
        upon billing therefor. Any non-material changes shall not require
        Landlord's consent.

6.3     PREPARATION OF PREMISES.

        (a)     Landlord. Landlord shall perform the work set forth on Exhibit C
                hereto and shall not be obligated to perform any other work to
                the Premises or Building, except as otherwise expressly set
                forth herein.

                                      -17-
<Page>

        (b)     By Tenant. All work in addition to that set forth on Exhibit C
                to prepare the Premises for Tenant's occupancy shall be done by
                Tenant at its sole cost and expense in accordance with the terms
                of this Lease.

        (c)     Any additional cost to Landlord in connection with the
                completion of the Premises in accordance with the terms of this
                Lease (including Exhibit C) resulting from Tenant Change Orders
                or Tenant Delay shall be promptly paid by Tenant to Landlord.
                For the purposes of the next preceding sentence, the term
                "additional cost to Landlord" shall mean any cost in excess of
                $5000 in the aggregate over and above such cost as would have
                been the aggregate cost to Landlord of completing the Premises
                in accordance with the terms of this Lease and Exhibit C had
                there been no Tenant Change Order or Tenant Delay, as such cost
                is reasonably determined by Landlord's Architect. Landlord shall
                pay to Tenant any additional costs to Tenant (meaning any costs
                in excess of $5000 in the aggregate over and above such costs as
                would have been the aggregate cost to Tenant of performing
                Tenant's Work in accordance with the terms of this Lease had
                there been no Landlord Change (as hereinafter defined)) which
                has resulted from a change made by Landlord to Landlord's Plans
                and Specifications which has not been approved by Tenant (a
                "Landlord Change"). Nothing contained in this provision shall
                limit or qualify or prejudice any other covenants, agreements,
                terms, provisions and conditions contained in this Lease.

        (d)     With Landlord's prior written consent, Tenant shall have the
                right to enter the Premises prior to the Commencement Date,
                without payment of rent, to perform such work or decoration as
                to be performed by, or under the direction or control of,
                Tenant. Such right of entry shall be deemed a license from
                Landlord to Tenant and any entry thereunder shall be at the risk
                of Tenant.

        (e)     Tenant shall be conclusively deemed to have agreed that Landlord
                has performed all of its obligations under this Article VI
                unless not later than the end of the second calendar month next
                beginning after the Commencement Date, Tenant shall give
                Landlord written notice specifying the respects in which
                Landlord has not performed any such obligations, except that
                with respect to latent defects, such period shall be eleven
                months.

        Landlord shall cooperate with Tenant in obtaining all permits and
        approvals as are necessary for the construction of the Tenant Work. The
        Term of this Lease shall commence (the "Commencement Date") upon the
        earlier to occur of (i) 180 days after the date that the Landlord Work
        is substantially completed (as defined below) or (ii) the date that
        Tenant first commences business operations within any part of the
        Premises; provided, however, that if Tenant commences business

                                      -18-
<Page>

        operations within some portion, but not all of the Premises prior to the
        expiration of such 180-day period then the Term shall only commence with
        respect to such portion.

        Landlord and Tenant and their contractors shall reasonably cooperate
        with each other in scheduling their work so that neither shall
        unreasonably delay or interfere with the work of the other. During the
        period when Landlord Work and Tenant Work are both being conducted,
        Landlord, Tenant and their architects and contractors shall have weekly
        meetings in order to discuss the status of the construction and
        coordinating construction activities with each other. In addition,
        Landlord shall permit Tenant and its contractors access to the Building
        prior to the date when the Landlord Work has been substantially
        completed at mutually agreed upon times so that Tenant may perform work
        which may be most timely and economically performed prior to the date of
        such substantial completion, such as, by way of example and not by way
        of limitation, access to part of the walls within the Building being
        enclosed so that Tenant and/or its contractors may install Tenant's
        computer, data and telephone lines, but in the performance of such early
        entry, Tenant shall not delay Landlord Work and Tenant's contractors
        shall cooperate completely with Landlord's contractors. Landlord shall
        give Tenant reasonable advance notice of its schedule for construction
        and reasonable dates for access by Tenant and its contractor.

        Landlord agrees to obtain from the general contractor performing the
        Landlord's Work and from the subcontractor performing portions thereof,
        construction warranties that for a period as determined by Landlord (but
        not less than one year) such work is free of material defects in
        workmanship and materials and conforms in all material respects to
        Landlord's final plans including a warranty for no less than ten years
        on the roof system of the Building. Landlord agrees to promptly replace
        or repair, at its expense, items of Landlord's Work which are then
        incomplete or do not conform to the Landlord's final plans as to which
        Tenant shall have given notice to Landlord within sixty days after the
        date of substantial completion of Landlord's Work except that with
        respect to latent defects, such period is extended to eleven months. All
        construction work required or permitted by this Lease shall be done in a
        good and workmanlike manner and in compliance with all applicable Legal
        Requirements. Each party or its architect may inspect the work of the
        other at reasonable times and shall promptly give notice of observed
        defect. Each party is authorized by the other to rely, in connection
        with design and construction upon approval and other actions on the
        party's behalf by any Construction Representative of the party named
        below or any person hereafter designated in substitution or addition by
        notice of the party relying: Tenant's Construction Representative: Kim
        Thurber, Landlord's Construction Representative: Fred Greatorex.

6.3A    LANDLORD'S PAYMENT. Upon satisfaction of the following conditions, and
        provided the Tenant is not then in default under this Lease beyond the
        expiration

                                      -19-
<Page>

        of applicable notice and cure periods (but such amount shall become due
        when Tenant cures any such default), Landlord shall pay to Tenant an
        amount equal to $30.00 per square foot of rentable area of the Premises
        (the "Tenant Allowance") as an inducement to Tenant to enter into this
        Lease:

        (a)     one third of such amount shall be payable by Landlord to Tenant
                no later than thirty (30) days after the date when the Tenant
                Approved Plans shall have been approved by Landlord, provided
                that at such date Tenant is not in default under this Lease
                beyond the expiration of applicable cure and/or notice periods
                (but such amount shall become due when Tenant cures any such
                default); (b) an additional one-third of such amount shall be
                paid to Tenant within thirty days after Tenant shall have
                completed one-third of the Tenant's Work, shall have furnished
                to Landlord partial lien waivers and releases from all
                contractors, materialmen and suppliers with respect to such
                work, and a certificate of Tenant's general contractor that such
                work has been completed to such extent; and (c) the remainder of
                such amount shall be paid to Tenant upon satisfaction of the
                following conditions:

                (i)     Tenant shall have substantially completed all of
                        Tenant's Work, shall have paid for such work in full and
                        shall have delivered to Landlord lien waivers in
                        recordable form from all materialmen, contractors and
                        suppliers (in excess of $10,000) with respect to such
                        work (with respect to any contractor, materialman or
                        supplier in respect of which Tenant has not delivered to
                        Landlord a lien waiver where such lien waiver is
                        required, then Landlord shall withhold from the Tenant
                        Allowance an amount equal to the unpaid balance of such
                        work or materials to such materialman, contractor or
                        supplier until such lien waiver has been received but
                        shall pay the remainder of such Tenant Allowance to
                        Tenant), and

                (ii)    Tenant shall have delivered to Landlord reasonable
                        evidence of the cost of the work in the form of paid
                        invoices, receipts and the like, and

6.3B    SUBSTANTIAL COMPLETION.

        (a)     Landlord's Work shall be treated as having been "substantially
                completed" for purposes of this Lease on the latest of:

                (i)     The date on which the Landlord's Work in the Premises as
                        described in Landlord's Plans and Specifications has
                        been completed except for Punch List Items;

                (ii)    The Architect certifies to Tenant that Landlord's Work
                        in the

                                      -20-
<Page>

                        Premises as described in Landlord's Plans and
                        Specifications has been substantially completed in
                        accordance with said plans;

                (iii)   the completion of any portion of the Landlord's Work
                        outside the Premises necessary to enable Tenant and its
                        contractor to commence the Tenant Work;

                (iv)    Building Systems, including, without limitation, the
                        heating, ventilation, air conditioning, plumbing,
                        mechanical, electrical, telephone, life safety and
                        telecommunications systems (to the extent to be provided
                        by Landlord according to the Landlord's Plans and
                        Specifications) are installed within the Building and
                        delivered to the Premises to the extent necessary to
                        permit the commencement, continuation and completion of
                        the Tenant's Work; and

                (v)     Landlord's Work outside the Premises shall be completed
                        to the extent necessary to deliver all utilities to the
                        Premises.

        On or about the date that Landlord's Work is substantially complete,
        Landlord's Construction Representative and Tenant's Construction
        Representative shall conduct a joint walk-through of the Premises and
        shall prepare a mutually acceptable inventory of "punch list" items (the
        "Punchlist Items"). With respect to Landlord's Work, Landlord shall
        cause all Punchlist Items to be completed within 30 days after the
        "delivery" thereof, except such Punchlist Items that cannot be completed
        due to seasonal conditions or because completion of the Tenant Work is
        necessary for the completion of such Landlord's Work, which in either
        case Landlord shall complete as soon as such condition reasonably
        permit, but in no event longer than 30 days, subject to delays due to
        Landlord's Force Majeure.

        Landlord and Tenant acknowledge that certain of Landlord's finish work
        in the lobby and in the bathrooms and in the elevators will not be
        performed by the date of such substantial completion but Landlord shall
        perform such work no later than 120 days after the date of substantial
        completion; provided, however, that if Tenant intends to occupy a
        portion or portions of the Premises prior to the expiration of such
        120-day period, Tenant may accelerate such period with respect to such
        portions by notice given to Landlord at least thirty (30) days prior to
        the end of such accelerated period.

        To the extent that any of Landlord's Work to the Building has not been
        completed and the lack of completion thereof delays Tenant in the
        completion of the Tenant Work (including any unreasonable interference
        with Tenant's contractors' access to the Premises) or in obtaining a
        certificate of occupancy then the 180 day period set forth above shall
        be extended to the extent of such Landlord Delay. In any

                                      -21-
<Page>

        case, by the end of such 180 day period and subject to Landlord's Force
        Majeure Landlord shall complete the construction of the plaza area.

6.4     REPAIRS TO BE MADE BY LANDLORD. Landlord agrees to keep in good order,
        condition and repair the Common Areas and common facilities of the
        Building, including, but not limited to, all HVAC, electrical, plumbing,
        security, life safety and other mechanical systems ("Building Systems")
        and the driveways and other common areas of the Lot, and the structure,
        foundations and roof of the Building, insofar as any of the foregoing
        affects the Premises or access thereto or the use thereof, and shall
        maintain the same in accordance with applicable laws, ordinances,
        governmental rules and regulations, directions and orders of officers of
        governmental agencies having jurisdiction except that where the same
        results from the specific nature of Tenant's use or any alterations or
        changes made by Tenant, Tenant shall reimburse Landlord for the cost
        thereof upon demand. Landlord shall in no event be responsible to Tenant
        for the condition of glass in the Premises or for the entry doors to the
        Premises, or with respect to any condition in the Premises or the
        Building caused by any act or neglect of Tenant or any contractor,
        agent, employee or invitee of Tenant, or anyone claiming by, through or
        under Tenant, Landlord shall restore the same and Tenant shall reimburse
        Landlord for the cost thereof upon demand. Landlord shall not be
        responsible to make any improvements or repairs to the Building or the
        Premises other than as expressed in this Section 6.4 unless otherwise
        expressly provided in this Lease. Landlord shall use all commercially
        reasonable efforts to minimize noise or vibration on the roof of the
        Building, and in connection therewith Landlord's design of the HVAC
        units and other equipment located on the roof shall be such that noise
        levels will not exceed 44 dBA or RC II 37 [equivalent NC 34 more or
        less] (the "Noise Standard"). Landlord shall cause all equipment located
        on the roof by other tenants to be designed to satisfy the Noise
        Standard, and Tenant shall cause any of its equipment located on the
        roof to be designed to satisfy the Noise Standard. If any equipment
        located on the roof by Landlord or other tenants shall not satisfy the
        Noise Standard in operation, then Landlord shall perform such work as
        shall be necessary so that such equipment shall satisfy the Noise
        Standard in operation, and if any equipment located on the roof by
        Tenant does not satisfy the Noise Standard in operation then Tenant
        shall perform such work as shall be necessary to cause such equipment to
        satisfy the Noise Standard in operation.

        Landlord shall never be liable for any failure to make repairs which,
        under the provisions of this Section 6.4 or elsewhere in this Lease,
        Landlord has undertaken to make unless: (a) Tenant has given notice to
        Landlord of the need to make such repairs as a result of a condition in
        the Building or in the Premises requiring any repair for which Landlord
        is responsible except that to the extent that the Landlord or its agent
        otherwise has actual knowledge of the need for such repair then such
        notice shall not be required and Landlord shall be required to commence
        to make such repairs within a reasonable time after Landlord has actual
        knowledge thereof;

                                      -22-
<Page>

        and (b) Landlord has failed to commence to make such repairs within five
        (5) business days after receipt of such notice or actual knowledge if
        any repairs are, in fact, necessary.

6.5     TENANT'S AGREEMENT. Tenant agrees that throughout the Lease Term Tenant
        will keep neat and clean and maintain in as good order, condition and
        repair as exists at the Commencement Date, reasonable wear and tear only
        excepted, the Premises and every part thereof, excepting only those
        repairs for which Landlord is responsible under the terms of this Lease
        or where the cause thereof is the result of Landlord's default under
        this lease and damage by fire or other casualty or as a consequence of
        the exercise of the power of eminent domain, and shall surrender the
        Premises at the end of the Term, in such condition. Without limitation,
        Tenant shall maintain and use the Premises in accordance with all
        applicable laws, ordinances, governmental rules and regulations,
        directions and orders of officers of governmental agencies having
        jurisdiction; and in accordance with the reasonable requirements of
        Landlord's and/or Tenant's insurers; provided, however, that in
        connection with such compliance with laws, etc. the Tenant shall not be
        required to make any structural alterations or changes to the Building
        or the Premises except where the same are required as a result of the
        specific nature of the use being made by Tenant of the Premises or by
        reason of any alterations or changes made by Tenant to the Premises.
        Tenant shall, at Tenant's own expense, obtain and maintain in effect all
        permits, licenses and the like required by applicable law for Tenant's
        particular use of the Premises or for any Alterations made by Tenant to
        the Premises. Landlord has entered into a certain traffic agreement with
        the Boston Redevelopment Authority and certain other agreements with the
        Boston Redevelopment Authority and in connection therewith encourages
        all employers at the Building to participate in the Corporate Pass
        Program of the Massachusetts Bay Transit Authority and the use of mass
        transit by persons working in Boston and to inform their employees of
        the benefit of using monthly transit passes and further encourages all
        employers in the Building to employ Boston residents. If required by any
        governmental authority, Landlord may request Tenant to report
        periodically on the number of Boston residents employed by Tenant at the
        Premises and the number of its employees who use mass transit passes
        issued under the Corporate Pass Program, and Tenant will use reasonable
        efforts to comply with such request. Tenant shall not permit or commit
        any waste, and Tenant shall be responsible for the cost of repairs which
        may be made necessary by reason of damage to any areas in the Building,
        including the Premises, by Tenant, Tenant's contractors or Tenant's
        agents, employees or invitees, or anyone claiming by, through or under
        Tenant.

        If repairs are required to be made by Tenant pursuant to the terms
        hereof, Landlord may demand that Tenant make the same forthwith, and if
        Tenant refuses or neglects to commence such repairs and complete the
        same within the applicable cure period after such demand, Landlord may
        (but shall not be required to do so)

                                      -23-
<Page>

        make or cause such repairs to be made. If Landlord makes or causes such
        repairs to be made, Tenant agrees that Tenant will forthwith, on demand,
        pay to Landlord the cost thereof, and if Tenant shall default in such
        payment, Landlord shall have the remedies provided for the nonpayment of
        rent or other charges payable hereunder.

6.6     FLOOR LOAD - HEAVY MACHINERY. Tenant shall not place a load upon any
        floor in the Premises exceeding the lesser of (a) the floor load per
        square foot of area which such floor was designed to carry as certified
        by Landlord's architect and (b) the floor load per square foot of area
        which is allowed by law. Landlord reserves the right to prescribe the
        weight and position of all business machines and mechanical equipment,
        including scales, which shall be placed so as to distribute the weight.
        Business machines and mechanical equipment shall be placed and
        maintained by Tenant at Tenant's expense in settings sufficient, in
        Landlord's reasonable judgment, to absorb and prevent vibration, noise
        and annoyance. Tenant shall not move any safe, heavy machinery, heavy
        equipment, freight, bulky matter or fixtures into or out of the Building
        without Landlord's prior consent, which shall not be unreasonably
        withheld, conditioned or delayed.

        If such safe, machinery, equipment, freight, bulky matter or fixtures
        requires special handling, Tenant agrees to employ only persons holding
        a Master Rigger's License to do said work, and that all work in
        connection therewith shall comply with applicable laws and regulations.
        Any such moving shall be at the sole risk and hazard of Tenant and
        Tenant will exonerate, indemnify and save Landlord harmless against and
        from any liability, loss, injury, claim or suit resulting directly or
        indirectly from such moving. Tenant shall schedule such moving at such
        times as Landlord reasonably shall require for the convenience of the
        normal operations of the Building.

                                   ARTICLE VII
                      SERVICES TO BE FURNISHED BY LANDLORD
                               AND UTILITY CHARGES

7.1     LANDLORD'S SERVICES. At Landlord's sole cost and expense but subject to
        reimbursement pursuant to the terms hereof, Landlord covenants during
        the Lease Term during the hours of 8 a.m. to 6 p.m., Monday through
        Friday, and 8 a.m. to 1 p.m. on Saturdays, holidays (New Year's Day,
        President's Day, Memorial Day, July 4th, Labor Day, Thanksgiving and
        Christmas) excepted ("Normal Building Operating Hours"):

        (a)     to provide heating and air conditioning in the Premises during
                the normal heating and air conditioning seasons, and the
                Building heating and air conditioning systems shall be designed
                to provide heating and air conditioning in compliance with the
                specifications attached as Exhibit F;

                                      -24-
<Page>

        (b)     at all times, to furnish hot and cold water for ordinary toilet,
                lavatory and drinking purposes (Landlord is not required to
                furnish water for kitchens or kitchenettes). If Tenant requires
                water for any other purpose, including without limitation for a
                kitchen, Tenant shall pay the Landlord a fair and equitable
                charge therefor determined by Landlord to reimburse Landlord for
                the cost of such water and related sewer use charge (including a
                charge to reimburse Landlord for the cost of metering Tenant's
                usage);

        (c)     to furnish non-exclusive passenger elevator service and, where
                provided, exclusive elevator service. Subject to the terms of
                Section 2.2 of this Lease, access to the Premises through
                elevators shall be provided on a 24-hour basis each day of the
                year, but subject to such reasonable rules and regulations for
                security as the Landlord may reasonably establish; and

        (d)     unless Tenant elects otherwise as provided below, to furnish
                cleaning services for the Premises and Common Areas and elevator
                reasonably consistent with such services set forth on Exhibit I
                hereto.

        (e)     to provide electricity to the Premises at least equal to eight
                watts per Rentable Square Foot, exclusive of HVAC; and

        (f)     provide for the clearance and removal of snow and ice from the
                driveways and walkways on the Lot and the maintenance, in a good
                and attractive condition, of all landscaping on the Lot.

        The services to be provided by Landlord under this Section 7.1 shall be
        at least consistent in quality with the quality of services in
        facilities similar to the Building in the general vicinity of the
        Building. In addition, Landlord agrees to furnish, at Tenant's expense,
        HVAC at times other than Normal Business Operating Hours, upon Tenant's
        request and such additional special services as may be mutually agreed
        upon by Landlord and Tenant, upon reasonable and equitable rates from
        time to time established by Landlord, and Tenant shall pay therefor
        promptly after receipt of billing at the time of Tenant's next Fixed
        Rent payment. Landlord's initial charge for overtime HVAC is $50.00 per
        hour.

        Tenant may elect to provide janitorial services to the Premises by
        notice to Landlord to such effect given no later than May 1, 2002.

        If Tenant has elected that it will provide its own janitorial service it
        may at any time thereafter elect that Landlord shall provide such
        service but such election cannot be made more than once in any two year
        period and then at least six months prior to date upon which Landlord is
        to begin furnishing such service. If, however, Tenant has at any time
        elected not to provide such service it may thereafter elect to provide
        such service for itself provided that it gives Landlord at least twelve
        months advance notice thereof and shall not make any such election

                                      -25-
<Page>

        more often than once in any twenty-four month period. Landlord and
        Tenant shall coordinate so that Tenant's provision of its own janitorial
        service shall commence at a time when Landlord's then current contract
        for the provision of janitorial services to the Building is ending or up
        for renewal. If at any time Tenant has elected to provide its own
        janitorial service then there shall be a fair reduction in rent by the
        cost which Landlord would have incurred in an arms-length commercially
        reasonable context to provide such service less any extra cost which the
        Landlord incurs in providing janitorial service to the rest of the
        Building as a result of the deletion of Tenant's Premises from
        Landlord's contract with its janitorial contractor, and during such
        period of time, the Base Operating Expenses shall be reduced by the
        amount which Landlord would have incurred in providing such janitorial
        services to Tenant's Premises during the Base Year or in fact the amount
        which Landlord actually incurred during such Base Year, as the case may
        be.

7.2     PAYMENT OF UTILITY CHARGES. With respect to electricity for lighting and
        equipment in the Premises, prior to the Commencement Date the same shall
        be separately metered by Landlord, and Tenant agrees to pay all bills
        therefor promptly to the utility company furnishing the same and, if
        requested by Landlord, provide Landlord with evidence of such payment.
        If such utility company shall have a lien on the Premises for nonpayment
        of such charges and Tenant shall fail at any time to make payment of
        same, without limitation of Landlord's rights on account of such
        failure, Tenant shall thereafter, if requested by Landlord, pay to
        Landlord, when monthly Fixed Rent is next due and thereafter on
        Landlord's demand, an amount reasonably estimated by Landlord to be
        sufficient to discharge any such lien. Such amount or such portion
        thereof as shall be unexpended at the expiration of this Lease shall,
        upon full performance of all Tenant's obligations hereunder, be repaid
        to Tenant without interest.

                                  ARTICLE VIII
                      REAL ESTATE TAXES AND OTHER EXPENSES

8.1     TENANT'S SHARE OF REAL ESTATE TAXES.

        (a)     For the purposes of this Section:

                (i)     The term "Tax Period" shall mean the period during which
                        Taxes (as hereinafter defined) are required to be paid
                        under applicable law. Thus, under the law presently in
                        effect in the Commonwealth of Massachusetts, Tax Period
                        means the period from July 1 of a calendar year to June
                        30 of the subsequent calendar year. Suitable adjustment
                        in the determination of Tenant' obligation under this
                        Section 8.1 shall be made in the computation for any Tax
                        Period which is greater than or less than twelve (12)
                        full calendar months.

                                      -26-
<Page>

                (ii)    The term "Taxes" shall mean all real estate taxes and
                        assessments (which term, for purposes of this provision,
                        shall include water and sewer use charges which are not
                        separately metered to Tenant or any other occupant of
                        the Building), special or otherwise, levied or assessed
                        upon or with respect to the Lot and Building or any part
                        thereof and all ad valorem taxes for any personal
                        property of Landlord used in connection therewith. As of
                        the date of delivery of the Premises to Tenant, the Lot
                        shall be a single tax parcel, separately assessed,
                        including no taxable improvements other than the
                        Building (upon its completion) and the Common Areas
                        existing as of the Commencement Date. Should the
                        Commonwealth of Massachusetts, or any political
                        subdivision thereof, or any other governmental authority
                        having jurisdiction over the Lot and Building, (1)
                        impose a tax, assessment, charge or fee, which Landlord
                        shall be required to pay, by way of substitution for or
                        as a supplement to such real estate taxes and ad valorem
                        personal property taxes, or (2) impose an income or
                        franchise tax or a tax on rents in substitution for or
                        as a supplement to a tax levied against the Lot and
                        Building or any part thereof and/or the personal
                        property used in connection with the Lot or Building or
                        any part thereof, all such taxes, assessments, fees or
                        charges (hereinafter defined as "in lieu of taxes")
                        shall be deemed to constitute Taxes hereunder. Except as
                        hereinabove provided with regard to "in lieu of taxes",
                        Taxes shall not include any inheritance, estate,
                        succession, transfer, gift, franchise, net income or
                        capital stock tax or any so-called linkage payments. If
                        any betterment assessment is made against the Lot, and
                        such assessment may be paid in installments over a
                        number of years, then there shall be included in each
                        Tax Period's taxes only the installment of (or portions
                        thereof) falling due within such Tax Period had Landlord
                        elected to pay the same over the longest period
                        permitted by law (together with any statutory interest
                        thereon) whether or not Landlord so elects. If Landlord
                        shall obtain any abatement or reduction in Taxes a
                        portion of which has already been paid by Tenant under
                        this Section 8.1, then after Landlord deducts therefrom
                        the reasonable costs and expenses incurred by Landlord
                        in obtaining such abatement or reduction, Landlord shall
                        pay to Tenant Tenant's Share of such abatement or
                        reduction but not in excess of the amount of Taxes paid
                        in respect thereof paid by Tenant under this Section 8.1
                        for the Tax Period in question.

        (b)     In the event that the Taxes imposed with respect to the Lot and
                Building shall be greater during any Tax Period than the Base
                Taxes:

                                      -27-
<Page>

                (i)     Tenant shall pay to Landlord, as additional rent,
                        Tenant's Share of the amount by which the Taxes imposed
                        with respect to the Lot and Building for such Tax Period
                        exceed the Base Taxes, apportioned for any fraction of a
                        Tax Period contained within the Term, and

                (ii)    Landlord shall submit to Tenant a statement setting
                        forth the amount of such additional rent, and within
                        thirty (30) days after the delivery of such statement
                        (whether or not such statement shall be timely), Tenant
                        shall pay to Landlord the payment required under
                        subparagraph (i) above. So long as Taxes shall be
                        payable in installments under applicable law, Landlord
                        may submit such statements to Tenant in similar
                        installments. The failure by Landlord to send any
                        statement required by this subparagraph shall not be
                        deemed to be a waiver of Landlord's right to receive
                        such additional rent except that in no event shall
                        Tenant be responsible for Taxes not billed to Tenant
                        (other than in an abatement situation) within two years
                        after the date due to the appropriate governmental
                        authority. At Tenant's request, Landlord shall submit to
                        Tenant supporting back-up documentation with respect to
                        any statement which Landlord has delivered to Tenant for
                        payment.

        (c)     Tenant's payments in respect of increases in Taxes shall be
                adjusted on a per diem basis for and with respect to any portion
                of the Term which does not include an entire Tax Period.

        (d)     If Tenant is obligated to pay any additional rent as aforesaid
                with respect to any Tax Period or fraction thereof during the
                Term, then Tenant shall pay, as additional rent, on the first
                day of each month of the next ensuing Tax Period, estimated
                monthly tax escalation payments in an amount from time to time
                reasonably estimated by Landlord. Estimated monthly tax
                escalation payments for each ensuing Tax Period shall be made
                retroactively to the first day of the Tax Period in questions.
                Following the close of each Tax Period and with respect to which
                Tenant is obligated to pay any additional rent as aforesaid,
                Landlord shall submit the statement set forth in paragraph
                (b)(ii) of this Section 8.1 and in the event the total of the
                estimated monthly tax escalation payments theretofore made by
                Tenant to Landlord for such Tax Period does not equal Tenant's
                Share of the Taxes in excess of the Base Taxes, Tenant shall pay
                any deficiency to Landlord as shown by such statement within
                thirty (30) days after the delivery of such statement (whether
                or not such statement shall be timely). If the total of the
                estimated monthly tax escalation payments paid by Tenant during
                such Tax Period exceed the actual amount of Tenant's Share of
                the Taxes in excess of the Base Taxes, Landlord shall pay the

                                      -28-
<Page>

                same to Tenant within thirty (30) days or, at Landlord's Option
                credit the amount of such overpayment against subsequent
                obligations of Tenant for rent under this lease (but Landlord
                shall refund such overpayment if the Term has ended and Tenant
                has no further obligations to Landlord under this lease).

        (e)     When the applicable tax bill is not available prior to the end
                of the Term, then a tentative computation shall be made by
                Landlord on the basis of the Taxes for the next prior Tax
                Period, with a final adjustment to be made between landlord and
                Tenant promptly after Landlord shall have received the
                applicable tax bill.

        (f)     Payments by Tenant to Landlord on account of Taxes shall not be
                considered as being held in trust, in escrow or the like, by
                Landlord,; it being the express intent of Landlord and Tenant
                that Tenant shall in no event be entitled to receive interest
                upon, or any payments on account of earnings or profits derived
                from, such payments by Tenant to Landlord. Landlord shall have
                the same rights and remedies for the non-payment by Tenant of
                any amounts due on account of such Taxes as Landlord has
                hereunder for the failure of Tenant to pay the Fixed Rent.

                excess shall be calculated as follows: with respect to insurance
                costs, Tenant's Share shall be a fraction equal to Tenant's Tax
                Share and with respect to all other Operating Expenses Tenant's
                Share shall be equal to a fraction, the numerator of which is
                the Rentable Area of the Premises and the denominator of which
                is the Rentable Area of all office space within the Building,
                including the Premises.

        (d)     Said additional rent shall, with respect to the Operating Years
                in which the Commencement Date and end of the Term of this Lease
                fall, be adjusted to that proportion thereof as the portion of
                the Term of this Lease falling within such Operating Year bears
                to the full Operating Year. If Landlord shall change its
                Operating Year, appropriate adjustment shall be made for any
                Operating Year less than twelve months which may result.

        (e)     Any additional rent payable by Tenant under this Section 8.2
                shall be paid within thirty (30) days after Landlord has
                furnished Tenant with the Statement described above in paragraph
                (b) of this Section 8.2.

        (f)     If with respect to any Operating Year or fraction thereof during
                the Term, Tenant is obligated to pay any additional rent in
                respect of increases in such Operating Expenses as aforesaid,
                then Tenant shall pay, as additional rent, on the first day of
                each month of the next ensuing Operating Year, estimated monthly
                operating escalation payments in an amount from time to time
                reasonably estimated by Landlord to be sufficient to cover, in
                the aggregate, a sum equal to Tenant's Share of such increase in
                Operating Expenses for such year. If the estimated monthly
                operating escalation payments theretofore made for such
                Operating Year by Tenant are greater than the amount due as
                additional rent in respect thereof according to the statement
                furnished Tenant by Landlord pursuant to paragraph (b) of this
                Section 8.2, Landlord shall pay the same to Tenant within thirty
                (30) days, or, at Landlord's election, credit the amount of such
                overpayment against subsequent obligations of Tenant for
                additional rent under this Lease (but Landlord shall refund such
                overpayment if the Term has ended and Tenant has no further
                obligation to Landlord under the Lease); but if such amount due
                as such additional rent for said Operating Year is greater than
                the estimated monthly operating escalation payments theretofore
                made on account of such period, Tenant shall make suitable
                payment to Landlord

                                      -34-
<Page>

                within the time set forth in paragraph (e) of this Section 8.2.
                This provision shall survive the end of the Lease Term.

        (g)     If in the Base Year or any Operating Year the Building is not
                95% occupied (above the ground floor retail) during all or any
                portion of such year or if in the Base Year or in any Operating
                Year the Operating Expenses are artificially low due to
                incentives, credits, warranties, rebates, offsets and other
                extraordinary and one-time payments or the like ("Rebates"), the
                Operating Expenses shall be increased equitably to reflect such
                Rebates or the vacancies within the Building (above the retail
                ground floor) to the extent that Operating Expenses would be
                greater had the Building been at least 95% occupied (above the
                ground floor) during such year.

        (h)     Anything in this Lease to the contrary notwithstanding, it is
                expressly understood and agreed that the designation or use by
                Landlord from time to time of portions of the Lot or Building as
                common areas shall not restrict the Landlord's use of such areas
                for improvements, structures and/or for retail, office or such
                other purposes as the Landlord shall determine, the Landlord
                hereby reserving the unrestricted right to build, and to,
                subtract from, lease, license, relocate and/or otherwise use
                (temporarily and/or permanently), any improvements, kiosks or
                other structures, parking areas, sidewalks or other such common
                areas of facilities anywhere upon or within the Lot or Building
                for office, retail, or such other purposes as Landlord shall
                determine. Nothing herein shall limit the right of the Landlord
                to change the use to which any part of the Building will be used
                from the purposes specified herein. Landlord shall not exercise
                its rights under this Subsection (h) in a manner that will
                unreasonably interfere with Tenant's access to, or use of, the
                Premises, or that would materially increase Tenant's obligations
                or decrease Tenant's rights under this Lease.

        (i)     Within 90 days after receipt of each statement delivered under
                this Section, Tenant or its agent (if a certified public
                accountant) shall have the right to examine and copy Landlord's
                records relating to the Operating Expenses and Taxes and the
                calculation of Tenant's Share thereof. Landlord shall make all
                its records relating to the calculation of Operating Expenses
                available to Tenant or its agents, at reasonable times upon
                reasonable advance notice at Landlord's Present Mailing Address
                or such other location as Landlord shall specify. No such audit
                and examination may be made by any person or entity employed in
                whole or in part on a so-called contingency basis. Tenant shall
                maintain the confidentiality of all information which it
                receives as a result of such examination and shall not disclose
                the same except in connection with litigation between Landlord
                and Tenant. If Tenant fails to notify Landlord within such
                90-day period

                                      -35-
<Page>

                that it determines to examine such statement, such statement
                shall be deemed an account between Landlord and Tenant. In the
                event Tenant has been overcharged for Operating Expenses and/or
                Taxes and such overcharge is five percent (5%) or more of the
                amount actually due from Tenant with respect to Operating
                Expenses or Taxes, as the case may be, Landlord shall also pay
                all reasonable costs incurred by Tenant in conducting such
                audit. Tenant may pay any charge in respect of Operating
                Expenses or Taxes under protest and if it shall be determined
                that Tenant has overpaid then Landlord shall promptly refund
                Tenant the amounts for which Tenant has overpaid.

                                   ARTICLE IX
                    INDEMNITY AND PUBLIC LIABILITY INSURANCE

9.1     TENANT'S INDEMNITY. To the maximum extent this agreement may be made
        effective according to law, Tenant agrees to indemnify and save harmless
        Landlord from and against all claims of whatever nature arising from any
        willful misconduct or negligence of Tenant, or Tenant's contractors,
        licensees, invitees, agents, servants or employees, or arising from any
        accident, injury or damage whatsoever caused to any person, or to the
        property of any person, occurring after the commencement of construction
        work by Tenant where Tenant has exclusive possession of the Premises,
        and until the end of the Lease Term and thereafter, so long as Tenant is
        in occupancy of any part of the Premises, within the Premises, or
        arising from any accident, injury or damage occurring outside of the
        Premises, where such accident, damage or injury results from a negligent
        act or omission or the willful misconduct on the part of Tenant or
        Tenant's agents, employees, contractors, or invitees. To the maximum
        extent this agreement may be made effective according to law, Landlord
        agrees to indemnify and save harmless Tenant from and against all claims
        of whatever nature arising from any act, omission or negligence of
        Landlord or Landlord's contractors, agents, servants or employees and
        occurring in the Building or the Lot.

        The foregoing indemnity and hold harmless agreements shall include
        indemnity against all costs, expenses and liabilities incurred in or in
        connection with any such claim or proceeding brought thereon, and the
        defense thereof.

9.2     PUBLIC LIABILITY INSURANCE. Tenant agrees to maintain in full force and
        effect from the date on which Tenant first enters the Premises for any
        reason, throughout the Lease Term, and thereafter so long as Tenant is
        in occupancy of any part of the Premises, a policy of Commercial General
        Liability insurance on an occurrence basis in accordance with the
        broadest form of such coverage as is available from time to time in the
        jurisdiction in which the Premises are located. The minimum limits of
        liability of such insurance shall be $3,000,000 combined single limit or
        shall be for such higher limits, if directed by Landlord, as are
        customarily carried in that area in which the Building is located upon
        buildings

                                      -36-
<Page>

        such as the Building, but Landlord shall not require higher limits
        during the first five years of the term of this Lease.

        The policy shall also include, but shall not be limited to the following
        extensions of coverage:

        1.      Contractual Liability, covering Tenant's liability assumed under
                this Lease; and

        2.      Personal Injury Liability in the amount of $3 million annual
                aggregate, expressly deleting the exclusion relating to
                contractual assumptions of liability.

        Tenant's insurance under this Section 9.2 may be provided by a primary
        policy and a so-called umbrella policy.

        Tenant further agrees to maintain a Workers' Compensation and Employer's
        Liability Insurance policy. The limit of liability as respects
        Employers' Liability coverage shall be no less than $5,000,000 per
        accident.

        Except for Workers' Compensation and Employers' Liability coverage,
        Tenant agrees that Landlord (and such other persons as are in privity of
        estate with Landlord as may be set out in notice from time to time) are
        named as additional insureds on a primary basis. Further, all policies
        shall be noncancellable and nonamendable with respect to Landlord and
        Landlord's said designees without 30 days' prior written notice to
        landlord. A duplicate original or a Certificate of Insurance evidencing
        the above agreements shall be delivered to Landlord prior to entry on
        the Premises.

9.3     TENANT'S RISK. To the maximum extent this agreement may be made
        effective according to law, Tenant agrees to use and occupy the Premises
        and to use such other portions of the Building as Tenant is herein given
        the right to use at Tenant's own risk; and Landlord shall have no
        responsibility or liability for any loss of or damage to fixtures or
        other personal property of Tenant for any reason whatsoever. The
        provisions of this Section shall be applicable from and after the
        execution of this Lease and until the end of the Lease Term, and during
        such further period as Tenant may use or be in occupancy of any part of
        the Premises or of the Building. Nothing in this Section 9.3 shall act
        to exculpate the Landlord from its negligence or willful misconduct or
        the negligence or willful misconduct of its servants, agents or
        employees.

9.4     INJURY CAUSED BY THIRD PARTIES. To the maximum extent this agreement may
        be made effective according to law, Tenant agrees that Landlord shall
        not be responsible or liable to Tenant, or to those claiming by, through
        or under Tenant, for any loss or damage that may be occasioned by or
        through the

                                      -37-
<Page>

        acts or omissions of persons occupying adjoining premises or any part of
        the premises adjacent to or connecting with the Premises or any part of
        the Building, or otherwise or for any loss or damage resulting to Tenant
        or those claiming by, through or under Tenant, or its or their property,
        from the breaking, bursting, stopping or leaking of electric cables and
        wires, water, gas, sewer or steam pipes, and from roof leaks and the
        like. Nothing in this Section 9.4 shall act to exculpate the Landlord
        from its negligence or willful misconduct or the negligence or willful
        misconduct of its servants, agents or employees.

9.5     The foregoing provisions of this Article IX (as well as any other
        provisions dealing with indemnity and like by Tenant of Landlord) shall
        be deemed to be modified in each case by the insertion in the
        appropriate place of the language "except as otherwise provided in Mass.
        GL. Ter. ED., c. 186, Section 15".

9.6     During the Lease Term, Landlord shall secure and carry (a) a policy of
        commercial general liability insurance covering Landlord on an
        occurrence basis in an amount not less than $5 million for claims based
        on bodily injury (including death), personal injury and property damage
        relating to the Building and the Lot; and (b) a policy of property
        insurance covering the Building and the other improvements on the Lot,
        not including the Tenant Work, for direct risk of physical loss, in an
        amount equal to the full replacement cost of the Building or other
        improvements on the Lot above footings and foundations. In the event
        either party fails to maintain and enforce the policies of insurance
        required hereunder, the party failing to maintain such policies shall be
        deemed to have received the maximum insurance proceeds which would have
        been payable under such policies had they been maintained for the
        purposes required.

                                    ARTICLE X
                          LANDLORD'S ACCESS TO PREMISES

10.1    LANDLORD'S RIGHT OF ACCESS. Upon reasonable advance notice to Tenant
        (which notice need not be given in the case of an emergency), Landlord
        shall have the right to enter the Premises at all reasonable business
        hours and after normal business hours for the purpose of inspecting or
        making repairs to the same, and upon reasonable advance notice to
        Tenant, Landlord shall also have the right to make access available at
        all reasonable hours to prospective or existing mortgagees or purchasers
        of any part of the Building. Any such right of entry shall be exercised
        in a manner so as to minimize interference with Tenant's use and
        occupancy of the Premises.

10.2    EXHIBITION OF SPACE TO PROSPECTIVE TENANTS. Upon reasonable advance
        notice to Tenant for a period of twelve (12) months prior to the
        expiration of the Lease Term (as the same has been extended), Landlord
        may have reasonable access to the Premises at all reasonable business
        hours for the purpose of exhibiting the same to prospective tenants, and
        may post suitable notice on the

                                      -38-
<Page>

        Building advertising the same for rent. Any such right of entry shall be
        exercised in a manner so as to minimize interference with Tenant's use
        and occupancy of the Premises. Landlord shall not be permitted to post
        notices for re-letting on Wing One unless Tenant is vacating the
        Premises except that Landlord may post notices for re-letting on retail
        portions of Wing One pertaining to such retail portions at ground level.

                                   ARTICLE XI
                           FIRE, EMINENT DOMAIN, ETC.

11.1    DAMAGE. In case during the term hereof the Premises shall be partially
        damaged (as distinguished from "substantially damaged", as that term is
        hereinafter defined) by fire or other casualty, the Landlord shall
        forthwith proceed to repair such damage and restore the Premises to the
        extent required of Landlord hereunder, to substantially their condition
        at the time of such damage, but the Landlord shall not be responsible
        for any delay which may result from Landlord's Force Majeure. In no
        event shall any of Landlord's restoration obligations under this Article
        XI pertain to any of Tenant's property or any alterations, changes or
        additions made by Tenant or any fixtures or improvements or equipment
        installed by Tenant.

11.2    SUBSTANTIAL DAMAGE. In case during the term hereof the Premises or the
        Garage or access thereto shall be substantially damaged or destroyed by
        fire or other casualty, the risk of which is covered by the Landlord's
        insurance, this Lease shall, except as hereinafter provided, remain in
        full force and effect, and the Landlord shall promptly after such damage
        and the determination of the net amount of insurance proceeds available
        to the Landlord, expend so much as may be necessary of such net amount
        to restore the Premises to the extent required of Landlord hereunder, at
        its cost (and not at Tenant's expense) (consistent, however, with zoning
        laws and building codes then in existence), to substantially the
        condition in which Premises, the Garage and access thereto were in at
        the time of such damage, except as herein provided, but the Landlord
        shall not be responsible for delay which may result from any cause
        beyond the reasonable control of the Landlord. Should the net amount of
        insurance proceeds available to the Landlord be insufficient to cover
        the cost of restoring the Premises, in the reasonable estimate of the
        Landlord, the Landlord may, but shall have no obligation to, supply the
        amount of such insufficiency and restore the Premises with all
        reasonable diligence or the Landlord may terminate this Lease by giving
        notice to the Tenant not later than one hundred twenty (120) days after
        the Landlord has determined the estimated net amount of insurance
        proceeds available to Landlord and the estimated cost of such
        restoration. In case of substantial damage or destruction, as a result
        of a risk which is not covered by the Landlord's insurance, the Landlord
        shall likewise be obligated to rebuild the Premises, all as aforesaid,
        unless the Landlord, within ninety (90) day after the occurrence of such
        event, gives written notice to the Tenant of the Landlord's election to
        terminate this

                                      -39-
<Page>

        Lease. For the purposes hereof, any deductible or other self-insurance
        by the Landlord shall be considered a part of the net insurance proceeds
        available for restoration.

        However, if the Premises, such access and the Garage shall be
        substantially damaged or destroyed by fire, windstorm, or otherwise
        within the last year of the Term of this Lease, as the same has been
        extended, either party shall have the right to terminate this Lease,
        provided that notice thereof is given to the other party not later than
        sixty (60) days after such damage or destruction; provided, however,
        that if Landlord has so exercised such option and if Tenant then has a
        right under this Lease to extend the term of this Lease then Tenant may
        render Landlord's exercise of such right of termination nugatory and of
        no force or effect provided that Tenant gives Landlord notice exercising
        such right of extension within ten (10) business days after its receipt
        of Landlord's notice of termination; and further provided that if only
        portions of the Premises have been damaged (on a floor by floor basis)
        and the access to such portions of the Premises have not been damaged
        Tenant shall have the right to occupy the portions of the Premises not
        so damaged for the remainder of what would have been the term of this
        Lease upon all the terms and conditions hereof but such occupancy must
        be on a floor by floor basis for any floor not so damaged. If said right
        of termination is exercised, this Lease and the term hereof shall cease
        and come to an end as of the date of said damage or destruction.
        Further, if the Premises, such access and the Garage shall be
        substantially damaged or destroyed by fire or casualty and the Landlord
        shall fail to commence the restoration thereof within sixty (60) days
        after the date of such damage or destruction (such 60 day period to be
        extended to the extent necessary for the Landlord to obtain insurance
        proceeds and building permits to effect such restoration and to the
        extent of any Landlord's Force Majeure), then Tenant may elect to
        terminate this Lease by notice to Landlord given before the Landlord has
        commenced such work and the termination shall take effect unless
        Landlord commences such work within thirty (30) days after such notice;
        and if after having commenced such restoration work, the Landlord shall
        fail to substantially complete such work within 270 days after its
        commencement, such 270-day period to be extended for up to ninety (90)
        days to the extent of delays due to Landlord's Force Majeure, then
        Tenant may elect to terminate this Lease by notice to Landlord given
        before Landlord shall have so completed such work and such termination
        shall take effect unless Landlord so completes such work within thirty
        (30) days after such notice.

        Unless this Lease is terminated as provided in this Section 11.2, or in
        Section 11.4, if the Premises shall be damaged or destroyed by fire or
        other casualty, then the Tenant shall (i) repair and restore all
        portions of the Premises not required to be restored by Landlord
        pursuant to this Article XI to substantially the condition which such
        portions of the Premises were in at the time of such casualty, (ii)
        equip the Premises with trade fixtures and all personal property

                                      -40-
<Page>

        necessary or proper for the operation of the Tenant's business, and
        (iii) open for business in the Premises - as soon thereafter as
        possible.

11.3    RENT ABATEMENT. In the event that the provisions of Section 11.1 or
        Section 11.2 of this Article XI shall be become applicable, the Fixed
        Rent and all other charges shall be abated or reduced proportionately
        during any period in which, by reason of such damage or destruction,
        there is substantial interference with the operation of the business of
        the Tenant in or access to the Premises or use of the Garage, having
        regard to the extent to which the Tenant in the exercise in good faith
        and prudent business judgment may be required to discontinue its
        business in the Premises, and such abatement or reduction shall continue
        for the period commencing with such destruction or damage and ending on
        the earlier to occur of (i) 120 days after the substantial completion by
        the Landlord of such work of repair and/or reconstruction as the
        Landlord is obligated to do or (ii) the Tenant having recommenced full
        operations in the Premises. In the event of termination of this Lease
        pursuant to this Article XI, this lease and the term hereof shall cease
        and come to an end as of the date of such damage or destruction.

11.4    DAMAGE TO BUILDING. If, however, the Building shall be substantially
        damaged or destroyed by fire or casualty and there shall be no
        substantial damage to the Premises or the Garage (and/or any spaces in
        the Garage) or access thereto, the Landlord shall promptly restore or
        cause to be restored (consistent, however, with zoning laws and building
        codes then in existence), the Building to substantially the condition
        thereof at the time of such damage, unless the Landlord, within a
        reasonable time after such loss, gives notice to the Tenant of the
        Landlord's election to terminate this Lease. If Landlord shall give such
        notice, then anything to this Article XI to the contrary notwithstanding
        this Lease shall terminate as of the date of such notice with the same
        force and effect as if such date were the date originally established as
        the expiration date hereof.

11.5    DEFINITIONS OF SUBSTANTIAL DAMAGE. The terms "substantially damaged" and
        "substantial damage", as said in this Article, shall have reference to
        damage of such a character as cannot reasonably be expected to be
        repaired or the Premises restored within sixty (60) days from the time
        that such repair or restoration work would be commenced.

11.6    TAKING. If the Premises are taken by condemnation or right of eminent
        domain then this Lease shall terminate as of the date that Tenant has
        been deprived of possession. If, however, less than all the Premises has
        been taken by eminent domain but there has been taken such portion
        thereof as to render the balance (when reconstructed) unsuitable for the
        purposes of the Tenant shall be taken by condemnation or right of
        eminent domain, or if access to the Premises is materially, adversely
        and permanently affected by such a taking or if more than ten (10)
        parking spaces allocated to Tenant's use are taken by such condemnation
        or right of eminent domain and Landlord promptly does not provide
        alternative

                                      -41-
<Page>

        spaces to Tenant reasonably acceptable to Tenant, Tenant, upon written
        notice to the Landlord, shall be entitled to terminate this lease,
        provided that such notice is given not later than thirty (30) days after
        the Tenant has been deprived of possession. For the purposes of this
        Article, any deed or other transfer of title in lieu of any such taking
        shall be treated as such a taking. Moreover, for the purposes of this
        Article, such a taking of the Tenant's entire leasehold interest
        hereunder in the Premises (or assignment or termination in lieu thereof)
        shall be treated as a taking of the entire Premises, and in such event
        the Tenant shall be treated as having been deprived of possession on the
        effective date thereof. Should any part of the Premises be so taken or
        condemned, and should this Lease not be terminated in accordance with
        the foregoing provision, the Landlord covenants and agrees within a
        reasonable time after such taking or condemnation, and the determination
        of the Landlord's award therein, to expend so much as may be necessary
        of the net amount which may be awarded to the Landlord in such
        condemnation proceedings, in restoring the Premises to an architectural
        unit as nearly like their condition prior to such taking as shall be
        practicable. Should the net amount so awarded to the Landlord be
        insufficient to cover the cost of restoring the Premises, as estimated
        by the Landlord's architect, the Landlord may, but shall not be
        obligated to, supply the amount of such insufficiency and restore the
        Premises as above provided, with all reasonable diligence, or terminate
        this Lease. Where the Tenant has not already exercised any right of
        termination accorded to it under the foregoing portion of this
        paragraph, the Landlord shall notify the Tenant of the Landlord's
        election not later than ninety (90) days after the final determination
        of the amount of the award.

11.7    RENT ABATEMENT. In the event of any such taking of the Premises, the
        Fixed Rent and other charges or a fair and just proportion thereof,
        according to the nature and extent of the damage sustained, shall be
        suspended or abated until there has been restoration as aforesaid. If
        there is a permanent taking of a portion of the Premises and this Lease
        is not terminated, then there shall be a permanent abatement of the
        fixed rent and other charges on a fair and equitable basis.

11.8    AWARD. Landlord shall have and hereby reserves and accepts, and Tenant
        hereby grants and assigns to Landlord, all rights to recover for damages
        to the Building and the Lot and any part thereof, and the leasehold
        interest hereby created, and to compensation accrued or hereafter to
        accrue by reason of such taking, damage or destruction, as aforesaid,
        and by way of confirming the foregoing, Tenant hereby grants and
        assigns, and covenants with Landlord to grant and assign to Landlord all
        rights to such damages or compensation. Nothing contained herein shall
        be construed to prevent Tenant from prosecuting in any condemnation
        proceedings a claim for the value of any Tenant's usual trade fixtures
        and other improvements installed in the Premises by Tenant at Tenant'
        expense and for relocation expenses, provided that such action shall not
        affect the amount of compensation otherwise recoverable by Landlord from
        the taking authority.

                                   ARTICLE XII
                               LANDLORD'S REMEDIES

12.1    EVENTS OF DEFAULT. Any one of the following shall be deemed to an "Event
        of Default":

        A.      Failure on the part of Tenant to pay Fixed Rent, additional rent
                or other charges for which provision is made herein on or before
                the date on which the same become due and payable and such
                failure continues for ten (10) days after Landlord delivers to
                Tenant notice of such default.

                However, if (i) Landlord shall have sent to Tenant three (3)
                notices of default in the payment of Fixed Rent in any calendar
                year, even though the same shall have been cured and this Lease
                not terminated; and (ii) during the calendar year in which said
                notices of default have been sent by Landlord to Tenant, Tenant
                thereafter shall default in the payment of Fixed Rent - the same
                shall be deemed to be an Event of Default upon Landlord giving
                Tenant written notice thereof, without the ten (10) day grace
                period set forth above.

        B.      With respect to a non-monetary default under this Lease, failure
                of Tenant to cure the same within thirty (30) days following
                delivery of notice from Landlord to Tenant of such default or
                such longer period of time as is reasonably required to cure
                such default provided that Tenant commences to cure such default
                with due diligence and pursues the cure thereof with all due
                diligence. Notwithstanding the thirty (30) day cure period
                provided in the preceding sentence, Tenant shall be obligated to
                commence forthwith and to complete as soon as possible the
                curing of such default; and if Tenant fails so to do, the same
                shall be deemed to be an Event of Default.

                However, if (i) Landlord shall have sent to Tenant three notices
                of the same non-monetary default, in any calendar year, even
                though the same shall have been cured and this Lease not
                terminated; and (ii) during the calendar year in which said
                notices of default have been sent by Landlord to Tenant, Tenant
                thereafter shall default in the same or any similar non-monetary
                matter - the same shall be deemed to be an Event of Default upon
                Landlord giving the Tenant written notice thereof, and Tenant
                shall have no grace period within which to cure the same.

        C.      The commencement of any of the following proceedings, with such
                proceeding not being dismissed within sixty (60) days after it
                has begun: (i) the estate hereby created being taken on
                execution or by other process of law; (ii) Tenant being
                judicially declared bankrupt or insolvent

                                      -43-
<Page>

                according to law; (iii) an assignment being made of the property
                of Tenant for the benefit of creditors; (iv) a received,
                guardian, conservator, trustee in involuntary bankruptcy or
                other similar officer being appointed to take charge of all or
                any substantial part of Tenant's property by a court of
                competent jurisdiction, or (v) a petition being filed for the
                reorganization of Tenant under any provisions of the Bankruptcy
                Code now or hereafter enacted.

        D.      Tenant filing a petition for reorganization or for
                rearrangements under any provisions of the Bankruptcy Code now
                or hereafter enacted, and providing a plan for a debtor to
                settle, satisfy or to extend the time for the payment of debts.

        E.      Execution by Tenant of an instrument purporting to assign
                Tenant's interest under this Lease or sublet the whole or a
                portion of the Premises to a third party without Tenant having
                first obtained Landlord's prior express consent to said
                assignment or subletting where such consent is required
                hereunder.

        F.      The Tenant abandoning the Premises. For the purposes hereof
                abandonment of the Premises is not merely a vacating of the
                Premises but is abandonment as that term is legally defined and
                Tenant's failure to perform its obligations hereunder.

12.2    REMEDIES. Should any Event of Default occur then, notwithstanding any
        license of any former breach of covenant or waiver of the benefit hereof
        or consent in a former instance, Landlord lawfully may, in addition to
        any remedies otherwise available to Landlord, immediately or at any time
        thereafter, and without demand or notice (but in accordance with
        applicable laws), enter into and upon the Premises or any part thereof
        in the name of the whole and repossess the same as of Landlord's former
        estate, and expel Tenant and those claiming by, through or under it and
        remove its or their effects (without breach of the peace) without being
        deemed guilty of any manner of trespass, and without prejudice to any
        remedies which might otherwise be used for arrears of rent or preceding
        breach of covenant and/or Landlord may send notice to Tenant terminating
        the Term of this Lease; and upon the first to occur of: (i) entry as
        aforesaid; or (ii) the fifth (5th) day following the mailing of such
        notice of termination, the Term of this Lease shall terminate, but
        Tenant shall remain liable for all damages as provided for herein.

        Tenant covenants and agrees, notwithstanding any termination of this
        Lease as aforesaid or any entry or re-entry by Landlord, whether by
        summary proceedings, termination, or otherwise, to pay and be liable for
        on the days originally fixed herein for the payment thereof, amounts
        equal to the several installments of Fixed Rent and other charges
        reserved as they would become due under the terms of this

                                      -44-
<Page>

        Lease if this Lease had not been terminated or if Landlord had not
        entered or re-entered, as aforesaid, and whether the Premises be relet
        or remain vacant, in whole or in part, or for a period less than the
        remainder of the Term, or for the whole thereof, but in the event the
        Premises be relet by Landlord, Tenant shall be entitled to a credit in
        the net amount of rent received by Landlord in reletting, after
        deduction of all reasonable expenses incurred in reletting the Premises
        (including, without limitation, repairs, costs, brokerage fees, and the
        like but not remodeling costs), and in collecting the rent in connection
        therewith. It is specifically understood and agreed that Landlord shall
        be entitled to take into account in connection with any reletting of the
        Premises all relevant factors which would be taken into account by a
        sophisticated developer in securing a replacement tenant for the
        Premises, such as, but not limited to, the first class quality of the
        Building and the financial responsibility of any such replacement
        tenant; and Tenant hereby waives, to the extend permitted by applicable
        law, any obligation Landlord may have to mitigate Tenant's damages;
        provided, however, that in the event of the termination of this Lease as
        a result of the default of Tenant, Landlord shall use reasonable efforts
        to re-let the Premises, but in using such reasonable efforts, Landlord
        may take into account the factors set forth above and shall not be
        obligated to give priority to the re-letting of the Premises over other
        areas of the Building. As an alternative, at the election of Landlord,
        Tenant will upon such termination pay to Landlord, as damages, such a
        sum as at the time of such termination represents the present value
        (calculated using 2% in excess of the so-called Federal Funds Rate) of
        the amount of the excess, if any, of the total rent and other benefits
        which would have accrued to Landlord under this Lease for the remainder
        of the Lease Term if the lease terms had been fully complied with by
        Tenant over and above the then fair market rental value of the Premises
        for the balance of the Term. For purposes of this Article, if Landlord
        elects to require Tenant to pay damages in accordance with immediately
        preceding sentence, the total rent shall be computed by assuming that
        Tenant's payments in respect of increases in Taxes and Operating
        Expenses would be, for the balance of the unexpired term, the amount
        thereof (if any), respectively, for the immediately preceding Tax Period
        or Operating Year, as the case may be, payable by Tenant to Landlord.

        In the event of any breach by Tenant of any of the agreements, terms,
        covenants or conditions contained in this lease, Landlord shall be
        entitled to enjoin such breach and shall have the right to invoke any
        right or remedy allowed at law or in equity or by statute or otherwise
        as though reentry, summary proceedings, and other remedies were not
        provided for in this Lease.

        Each right and remedy of Landlord and Tenant provided for in this Lease
        shall be cumulative and shall be in addition to every other right or
        remedy provided for in this Lease not now or hereafter existing at law
        or in equity or by statute or otherwise, and the exercise or beginning
        of the exercise by Landlord or Tenant of any one or more of the rights
        or remedies provided for in this Lease or now or

                                      -45-
<Page>

        hereafter existing at law or in equity or by statute or otherwise shall
        not preclude the simultaneous or later exercise by Landlord or Tenant of
        any or all other rights or remedies provided for in this Lease or now or
        hereafter existing at law or in equity or by statute or otherwise.

        If any payment of rent or any other payment payable hereunder by Tenant
        to Landlord or Landlord to Tenant shall not be paid within five (5) days
        after the date when due, the same shall bear interest from the date when
        the same was payable until the date paid at the lesser of (a) twelve
        percent (12%) per annum, compounded monthly, or (b) the highest lawful
        rate of interest which may be charged without violating any applicable
        law; provided, however, that the first time in each calendar year that
        Landlord shall determine to charge such interest, it shall give notice
        thereof to Tenant and such interest shall be deemed waived if Tenant
        makes payment of the same within ten (10) days after delivery of such
        notice. Such interest payable by Tenant shall constitute additional rent
        payable hereunder and be payable upon demand therefor by Landlord.

        In the event of any litigation between Landlord and Tenant relating to
        this Lease, the prevailing party in such litigation by final court
        order, decree or judgment shall be entitled to be reimbursed by the
        other party for the reasonable and actual legal costs and expenses
        incurred by it in such litigation.

12.3    LANDLORD'S DEFAULT. Landlord shall in no event be in default in the
        performance of any of Landlord's obligations hereunder unless and until
        Landlord shall have failed to perform such obligations within thirty
        (30) days, or such additional time as is reasonably required to correct
        any such default, after notice by Tenant to Landlord properly specifying
        wherein Landlord has failed to perform any such obligations; provided,
        however, that in the event that any default of Landlord in the
        performance of its obligations shall pose the immediate threat of injury
        to person or damage to property, then Landlord shall use all reasonable
        efforts to commence to cure such default as soon as reasonably possible
        after it has received notice thereof from Tenant. In the event of a
        default by Landlord after the expiration of such notice and cure period
        which is of an emergency nature and which pertains to the maintenance of
        the Premises the Tenant shall be entitled to perform such maintenance on
        behalf of Landlord upon notice by Tenant to Landlord thereof, and if
        Tenant shall perform such maintenance on behalf of Landlord then
        Landlord shall promptly reimburse Tenant for the reasonable and actual
        costs thereof, but Tenant shall have no right to set-off any amounts so
        owed from Fixed Rent or other charges or rents due hereunder.

                                  ARTICLE XIII
                            MISCELLANEOUS PROVISIONS

13.1    EXTRA HAZARDOUS USE. Tenant covenants and agrees that Tenant will not do
        or permit anything to be done in or upon the Premises, or bring in
        anything or

                                      -46-
<Page>

        keep anything therein which shall increase the rate of insurance on the
        Premises or on the Building or any part thereof above the standard rate
        applicable to premises being occupied for the use to which Tenant has
        agreed to devote the Premises; and Tenant further agrees that in the
        event that Tenant shall do any of the foregoing, Tenant will promptly
        pay to Landlord, on demand, any such increase resulting therefrom which
        shall be due and payable as additional rent hereunder. Landlord will
        hold harmless, defend and indemnify Tenant and its successors and
        assigns against all claims, liabilities, loss, cost, and expenses,
        including reasonable attorneys' fees, incurred as a result of (i) any
        Hazardous Materials existing in, on or under the Premises, the Building
        or the Lot as of the date of this Lease, and (ii) the release, storage
        or disposal of Hazardous Materials in, on or under the Premises, the
        Building or the Lot by Landlord, its agents, employees or contractors,
        and the provision of this sentence shall survive the expiration or
        earlier termination of this Lease. The term "Hazardous Materials" shall
        mean any explosive, radioactive, hazardous wastes or hazardous
        substances or substances defined as "hazardous substances" in any
        federal, state or local laws, ordinance, regulation or governmental
        requirement including, without limitation, the Comprehensive
        Environmental Response, Compensation and Liability Act, 42 U.S.C.
        Sections 9601, et seq., Emergency Planning and Community Right-to-Know
        Act, 42 U.S.C. Sections 11001, et seq., Massachusetts Oil and Hazardous
        Material Release Prevention and Response Act, M.G.L. Chapter 21E, and
        Massachusetts Hazardous Waste Management Act, M.G.L. Chapter 21C.
        Landlord represents and warrants that, except as disclosed in the
        Release Abatement Measure (RAM) Plan dated March 2001 by Haley &
        Aldrich, Inc., it has no knowledge of the presence of any Hazardous
        Materials on the Premises, the Building or the Lot. Tenant will hold
        harmless, defend and indemnify Landlord and its successors and assigns
        against all claims, liabilities, loss, costs and expenses, including
        reasonable attorneys' fees, incurred as a result of the release, storage
        or disposal of Hazardous Materials in, on or under the Building or the
        Lot by Tenant, its agents, employees or contractors and the provisions
        of this sentence shall survive the expiration or earlier termination of
        this Lease.

13.2    WAIVER. Failure on the part of Landlord or Tenant to complain of any
        action or nonaction on the part of the other, no matter how long the
        same may continue, shall never be a waiver by Tenant or Landlord,
        respectively, of any of the other's rights hereunder. Further, no waiver
        at any time of any of the provisions hereof by Landlord or Tenant shall
        be construed as a waiver of any of the other provisions hereof, and a
        waiver at any time of any of the provisions hereof shall not be
        construed as a waiver at any subsequent time of the same provisions. The
        consent or approval of landlord or Tenant to or of any action by the
        other requiring such consent or approval shall not be construed to waive
        or render unnecessary Landlord's or Tenant's consent or approval to or
        of any subsequent similar act by the other. Any consent required of the
        Landlord in any provision of this Lease may be withheld by the Landlord
        in its sole discretion acting in good

                                      -47-
<Page>

        faith unless the provision requiring such consent specifically states
        that the Landlord shall not withhold such consent unreasonably.

        No payment by Tenant or acceptance by Landlord of a lesser amount than
        shall be due from Tenant to Landlord shall be treated otherwise than as
        a payment on account. The acceptance by Landlord of a check for a lesser
        amount with an endorsement or statement thereon, or upon any letter
        accompanying such check that such lesser amount is payment in full,
        shall be given no effect, and Landlord may accept such check without
        prejudice to any other rights or remedies which Landlord may have
        against Tenant. In no event shall Tenant ever be entitled to receive
        interest upon, or any payments on account of earnings or profits derived
        from any payments hereunder by Tenant to Landlord.

13.3    COVENANT OF QUITE ENJOYMENT. Tenant, subject to the terms and provisions
        of this Lease, upon payment of the Fixed Rent and other charges due
        hereunder and the observing, keeping and performing of all of the terms
        and provisions of this Lease on Tenant's part to be observed, kept and
        performed, shall lawfully, peaceable and quietly have, hold, occupy and
        enjoy the Premises during the Term hereof, without hindrance or ejection
        by any persons lawfully claiming under Landlord to have title to the
        Premises superior to Tenant; the foregoing covenant of quiet enjoyment
        is in lieu of any other covenant, expressed or implied; and it
        understood and agreed that this covenant and any and all other covenants
        of Landlord contained in this Lease shall be binding upon Landlord and
        Landlord's successors only with respect to breaches occurring during
        Landlord's and Landlord's successors' respective ownership of Landlord's
        interests hereunder. Further, Tenant specifically agrees to look solely
        to Landlord's then equity interest in the Lot and Building and available
        insurance proceeds for recovery of any judgment from Landlord; it being
        specifically agreed that Landlord (original or successor) shall never be
        personally liable for any such judgment, or for the payment of any
        monetary obligation to Tenant. The provision contained in the foregoing
        sentence is not intended to, and shall not limit any right that Tenant
        might otherwise have to obtain injunctive relief against Landlord or
        Landlord's successors in interest, or any action not involving the
        personal liability of Landlord (original or successor) to respond in
        monetary damages from Landlord's assets other than Landlord's equity
        interest aforesaid in the Lot and Building. With respect to any
        services, including, without limitation, heat, air-conditioning or water
        to be furnished by Landlord, or obligations to be performed by Landlord
        or Tenant hereunder, such party shall in no event be liable for failure
        to furnish or perform the same when (and the date for performance of the
        same shall be postponed so long as such party is) prevented from doing
        so by strike, lockout, accident, order or regulation of or by any
        governmental authority, or failure of supply, or inability by the
        exercise of reasonable diligence to obtain supplies, parts or employees
        necessary to furnish such services, or perform such obligations or
        because of war or other emergency, or for any cause beyond its
        reasonable control, or for any cause due to any act or neglect of the
        other or the

                                      -48-
<Page>

        other's servants, agents, employees, licensees, invitees or any person
        claiming by, through or under the other; provided, however, that in no
        event shall the foregoing excuse or delay such payment of rent or other
        monies. In no event shall either party ever be liable to the other for
        any indirect, special or consequential damages, including loss of
        business, suffered by it from whatever cause.

        In the event that due to the negligence or willful misconduct of
        Landlord or Landlord's agents or employees, if there is any interruption
        in utilities being supplied to the Premises and if as a result of such
        interruption, Tenant is prevented from using all or any material portion
        of the Premises for more than three (3) business days after notice
        thereof from Tenant to Landlord, than from and after the end of such
        3-business day period until the Premises (or such portion) is rendered
        usable, Annual Fixed Rent and additional charges for Operating Expenses
        allocable to the Premises or a just and proportionate part thereof shall
        be abated.

13.4    NOTICE TO MORTGAGEE AND GROUND LESSOR. After receiving notice (which
        notice contains an address for such holder or ground lessor from
        Landlord) that any person, firm or other entity holds a mortgage which
        includes the Premises as part of the mortgaged premises, or that is the
        ground lessor under a lease with Landlord, as ground lessee, which
        includes the Premises as part of the demised premises, no default or
        termination notice from Tenant to Landlord shall be effective unless and
        until a copy of the same is given to such holder or ground lessor, and
        the curing of any of Landlord's defaults by such holder or ground lessor
        shall be treated as performance by Landlord. For the purposes of this
        Section 13.4, Section 13.5 or Section 13.14, the term "mortgage"
        includes a mortgage on a leasehold interest of Landlord (but not one on
        Tenant's leasehold interest).

        The Tenant agrees that, in the event of foreclosure of any such mortgage
        or deed of trust to which this Lease is subordinate (or deed or
        assignment in lieu of foreclosure thereof), at the election of the
        holder, provided such holder has agreed or does agree to recognize
        Tenant's interest hereunder and not to disturb Tenant's occupancy of the
        Premises, the Tenant shall attorn to such holder (and its successors and
        assigns) as the successor holder of the Landlord's interest hereunder in
        which case, subject to any applicable terms and provisions of any
        written agreement between Tenant and such holder, this Lease shall
        continue in effect all as if it had been a lease entered into directly
        between Tenant and such holder (and its successors and assigns). The
        foregoing shall be self-operative; however, the Tenant agrees, upon
        receipt of written request so to do, to execute such instruments, if
        any, as may reasonably be required in order to give effect to the
        foregoing.

13.5    ASSIGNMENT OF RENTS. With reference to any assignment by Landlord of
        Landlord's interest in this Lease, or the rents payable hereunder,
        conditional in

                                      -49-
<Page>

        nature or otherwise, which assignment is made to the holder of a
        mortgage or ground lease on property which includes the Premises. Tenant
        agrees:

        (i)     that the execution thereof by Landlord, and the acceptance
                thereof by the holder of such mortgage, or the ground lessor,
                shall never be treated as an assumption by such holder or ground
                lessor of any of the obligations of Landlord hereunder, unless
                such holder or ground lessor shall, by notice sent to Tenant,
                specifically otherwise elect; and

        (ii)    that, except as aforesaid, such holder or ground lessor shall be
                treated as having assumed Landlord's obligations hereunder only
                upon foreclosure of such holder's mortgage or the taking of
                possession of the Premises, or in the case of a ground lessor,
                the assumption of Landlord's position hereunder by such ground
                lessor. In no event shall the acquisition of title to the
                Building or Lot or any part thereof and the land on which the
                same is located by a purchaser which, simultaneously therewith,
                leases the same back to the seller thereof, be treated as an
                assumption by operation of law or otherwise of Landlord's
                obligations hereunder, but Tenant shall look solely to such
                seller-lessee, and its successors from time to time in title,
                for performance of Landlord's obligations hereunder. In any such
                event, this Lease shall be subject and subordinate to the lease
                to such seller, provided that such Seller executes, acknowledges
                and delivers to Tenant a commercially reasonable non-disturbance
                and attornment agreement reasonably concurrently with such
                sale-leaseback. For all purposes such seller-lessee, and its
                successors in title, shall be the Landlord hereunder unless and
                until Landlord's position shall have been assumed by such
                purchaser-lessor.

13.6    MECHANICS LIENS. Tenant agrees promptly to discharge of record (either
        by payment or by the filing of the necessary bond, or otherwise) any
        mechanics', materialmen's or other lien against the Premises and/or
        Landlord's interest therein, which liens may arise out of any payment
        due for, or purported to be due for, any labor, services, materials,
        supplies or equipment alleged to have been furnished to or for Tenant
        in, upon or about the Premises.

13.7    NO BROKERAGE. Each of Landlord and Tenant warrants and represents that
        it has not dealt with any broker, in connection with the consummation of
        this Lease, and in the event any claim is made against the other party
        relative to dealings with brokers other than any broker named in Section
        1.2, the warranting party shall defend the claim with counsel reasonably
        approved by the other party and save harmless and indemnify the other
        party on account of loss, cost or damage which may arise by reason of
        any such claim. Landlord is not responsible for any fee due to Leggatt
        McCall.

                                      -50-

13.8    INVALIDITY OF PARTICULAR PROVISIONS. If any term or provision of this
        Lease or the application thereof to any person or circumstance shall, to
        any extent, be invalid or unenforceable, the remainder of this Lease, or
        the application of such term or provision to persons or circumstances
        other than those as to which it is held invalid or unenforceable, shall
        not be affected thereby, and each term and provision of this Lease shall
        be valid and enforceable to the fullest extend permitted by law.

13.9    PROVISIONS BINDING, ETC. Except as herein otherwise provided, the terms
        hereof shall be binding upon and shall inure to the benefit of the
        successors and assigns, respectively, of Landlord and Tenant and, if
        Tenant shall be an individual, upon and to his heirs, executors,
        administrators, successors and assigns. If two or more persons are named
        as Tenant herein, each of such persons shall be jointly and severally
        liable for the obligations of the Tenant hereunder, and landlord may
        proceed against any one without first having commenced proceedings
        against any other of them. The reference contained to successors and
        assigns of Tenant is not intended to constitute a consent to assignment
        by Tenant, but has reference only to those instances in which Landlord
        may later give consent to a particular assignment as required by those
        provisions of Article V hereof.

13.10   RECORDING. Tenant agrees not to record the within Lease, but each party
        hereto agrees, on the request of the other, to execute a so-called
        notice of lease in form recordable and complying with applicable law and
        reasonably satisfactory to Landlord's and Tenant's attorneys. (The form
        annexed hereto as Exhibit G is so satisfactory). In no event shall such
        document set forth the rent or other charges payable by Tenant under
        this Lease, and any such document shall expressly state that it is
        executed pursuant to the provisions contained in this Lease and is not
        intended to vary the terms and conditions of this Lease.

13.11   NOTICES. Whenever, by the terms of this Lease, notice shall or may be
        given either to Landlord or to Tenant, such notice shall be in writing
        and shall be delivered in hand with a written acknowledgment of receipt
        or sent by registered or certified mail, postage prepaid or delivered by
        recognized overnight or same day courier or by telecopy provided such
        notice concurrently sent by mail or overnight service:

                If intended for Landlord, addressed to landlord
                at the address set forth in Section 1.2 of this
                Lease (or to such other address or addresses as
                may from time to time hereafter be designated by
                Landlord by like notice). Fax No.: (781)
                769-2250.

                If intended for Tenant, addressed to Tenant at
                the address set forth in Section 1.2 of this
                Lease prior to Tenant's occupancy of the
                Premises and thereafter addressed to Tenant at
                the Premises, (or to such other

                                      -51-
<Page>

                address or addresses as may from time to time
                hereafter be designated by Tenant by like
                notice). Fax No.: (617) 241-8032

        All such notices shall be effective when delivered in hand, or on the
        earlier of receipt or refusal.

13.12   WHEN LEASE BECOMES BINDING. Employees or agents of Landlord have no
        authority to make or agree to make a lease or any other agreement or
        undertaking in connection herewith. The submission of this document for
        examination and negotiation does not constitute an offer to lease, or a
        reservation of, or option for, the Premises, and this document shall
        become effective and binding only upon the execution and delivery hereof
        by both Landlord and Tenant. All negotiations, considerations,
        representations and understandings between Landlord and Tenant are
        incorporated herein and may be modified or altered only by written
        agreement between Landlord and Tenant, and no act or omission of any
        employee or agent of Landlord shall alter, change or modify any of the
        provisions hereof.

13.13   PARAGRAPH HEADINGS. The paragraph headings throughout this instrument
        are for convenience and reference only, and the words contained therein
        shall in no way be held to explain, modify, amplify or aid in the
        interpretation, construction or meaning of the provisions of this Lease.

13.14   RIGHTS OF MORTGAGEE/GROUND LEASE. It is understood and agreed that the
        rights and interests of Tenant under this Lease shall be subject and
        subordinate to any mortgages or deeds of trust that may hereafter be
        placed upon the Building and/or the Lot, and/or any part of the
        foregoing, and to any and all advances to be made thereunder, and to the
        interest thereon, and all renewals, modifications, replacements and
        extensions thereof, if the mortgagee or trustee named in said mortgages
        or deeds of trust shall elect by notice delivered to Tenant to subject
        and subordinate the rights and interest of Tenant under this lease to
        the lien of its mortgage or deed of trust; it is further agreed that any
        mortgagee or trustee may elect to give the rights of interest of Tenant
        under this Lease priority over the lien of its mortgage or deed of
        trust. In the event of either such election, and upon notification by
        such mortgagee or trustee to Tenant to that effect, the rights and
        interest of Tenant under this Lease shall be deemed to be subordinate
        to, or to have priority over, as the case may be, the lien of said
        mortgage or deed of trust, whether this Lease is dated prior to or
        subsequent to the date of said mortgage or deed of trust. Tenant shall
        execute and deliver whatever instruments reasonably may be required for
        such purposes. It shall be a condition to any subordination of this
        Lease to any mortgage or deed of trust or ground lease encumbering the
        Building or Lot that Landlord shall obtain for Tenant an agreement (a
        "Non-Disturbance Agreement") from the holder thereof (each such party, a
        "Holder") which provides that (i) if any such Holder forecloses or takes
        a deed in lieu of foreclosure or otherwise exercises its rights under
        its mortgage or deed of trust or

                                      -52-
<Page>

        ground lease or (ii) if such Holder otherwise acquires Landlord's
        interest in this Lease, such Holder shall recognize Tenant's rights
        under this Lease, shall not disturb Tenant's occupancy of this Premise
        under this Lease and, subject to the terms and conditions of such
        agreement, shall assume Landlord's obligations under this Lease.

        This Lease is subject and subordinate to a certain Ground Lease (the
        "Ground Lease") between Massachusetts Turnpike Authority as groundlessor
        ("Groundlessor") and Landlord as groundlessee, a copy of which has been
        provided by Landlord to Tenant (the "Ground Lease"). The Ground Lease
        may be amended from time to time by Landlord, and this Lease shall be
        subject and subordinate to the Ground Lease as so amended provided that
        any such amendment does not materially adversely affect the rights and
        obligations of the Tenant hereunder. As soon as reasonably possible,
        Landlord shall obtain from the Groundlessor a subtenant non-disturbance
        agreement in the form annexed to the Ground Lease (a copy of which is
        annexed as Exhibit H hereto) for the benefit of Tenant and Tenant agrees
        to execute and deliver the same (for convenience purposes Tenant may be
        required to execute and deliver the same prior to its execution and
        delivery by Groundlessor). If Landlord does not obtain such
        non-disturbance agreement within sixty (60) days after the date of this
        Lease, then Tenant may terminate this Lease by notice to such effect to
        Landlord and if Tenant so exercises such right of termination and
        Landlord does not deliver such non-disturbance agreement within ten days
        thereafter, then this Lease shall terminate without further recourse to
        the parties. Wherever any consent of Groundlessor is required in
        connection with any consents to be made by Landlord hereunder, the
        failure of Groundlessor to give such consent shall be deemed to be a
        reason for the withholding of such consent by Landlord.

13.15   STATUS REPORT. Recognizing that both parties may find it necessary to
        establish to third parties, such as accountants, banks, mortgagees or
        the like, the then current status of performance hereunder, either
        party, on the request of the other made from time to time, will promptly
        furnish to Landlord, or the holder of any mortgage encumbering the
        Premises, or to Tenant, as the case may be, a statement of the status of
        any factual matter pertaining to this Lease, including, without
        limitation, acknowledgments to the best of such party's knowledge, that
        (or the extent to which) each party is in compliance with its
        obligations under the terms of this Lease.

13.16   TENANT'S FINANCIAL CONDITION. Upon Landlord's demand, which may be made
        only if required by lender or prospective lender to Landlord, and then
        no more often than once per year, Tenant shall furnish to Landlord, at
        Tenant's sole cost and expense, then current financial statements of
        Tenant and its guarantor (if any), audited (if audited statements have
        been recently prepared on behalf of Tenant or such guarantor) or
        otherwise certified as being true and correct by the chief financial
        officer of Tenant or such guarantor, as the case may be. So long as

                                      -53-
<Page>

        Tenant is a so-called public company, then Landlord waives the
        provisions of this Section 13.16.

13.17   NO PARTNERSHIP. The relationship of the parties hereto is that of
        landlord and tenant, and partnership, joint venture or participation is
        hereby created.

13.18.  HOLDING OVER. Any holding over by Tenant after the expiration of the
        Lease Term shall be treated as a tenancy at sufferance at 1.5 times the
        Fixed Rent and 10% of the additional rent herein provided to be paid
        during the last twelve (12) months of the Lease Term (prorated on a
        daily basis) and shall otherwise be on the terms and conditions set
        forth in this Lease, as far as applicable.

13.19   NON-SUBROGATION. Insofar as, and to the extent that, the following
        prevision may be effective without invalidating or making it impossible
        to secure insurance coverage obtainable from responsible insurance
        companies doing business in the locality in which the premises are
        located (even though extra premium may result therefrom): Landlord and
        Tenant mutually agree that, with respect to any hazard which is covered
        by insurance then being carried by them, or which could have been
        covered by a so-called All Risk policy, the one carrying (or who could
        have carried) such insurance and suffering such loss releases the other
        of and from any and all claims with respect to such loss; and they
        further mutually agree that their respective insurance companies shall
        have no right of subrogation against the other on account thereof.

13.20   GOVERNING LAW. This Lease shall be governed exclusively by the
        provisions hereof and by the laws of the Commonwealth of Massachusetts
        as the same may from time to time exist.

13.21   DEFINITION OF ADDITIONAL RENT. Without limiting any other provision of
        this Lease, it is expressly understood and agreed that Tenant's
        participation in Taxes, Operating Expenses, and all other charges which
        Tenant is required to pay hereunder, together with all interest and
        penalties that may accrue thereon, shall be deemed to be Additional
        Rent, and in the event of non-payment thereof by Tenant, Landlord shall
        have all of the rights and remedies with respect thereto as would accrue
        to Landlord for non-payment of Fixed Rent. Tenant's failure to object to
        any statement, invoice or billing rendered by Landlord within a period
        of three hundred sixty five (365) days after Tenant's receipt thereof
        shall constitute Tenant' acquiescence with respect thereto and shall
        render such statements, invoice or billing on account between landlord
        and Tenant.

13.22   EXTENSION OPTION. Upon and subject to the following terms and
        conditions, Tenant shall have the right to extend the term of this Lease
        for two consecutive periods of five (5) years each provided that (i)
        Tenant itself occupies at least 50% of the Premises, and (ii) it shall
        be a condition to the extension for the second such period that Tenant
        shall have timely and properly extended the term of this Lease

                                      -54-
<Page>

        for the first such period, and (iii) at the time of its exercise of any
        such extension and at the commencement of such extension period Tenant
        shall not be in default under this Lease beyond the expiration of
        applicable notice and cure periods, and (iv) Tenant shall give notice of
        such extension at least twelve (12) months prior to the then expiration
        of the term of this Lease. Provided that the Tenant has timely and
        properly complied with all the foregoing conditions, then, without the
        necessity of any further action, the term of this Lease shall be
        extended for such five-year extension period on all the terms and
        conditions hereof except that there shall be no further rights of
        extension after Tenant extends for the second five-year period and for
        and with respect to each such extension period annual Fixed Rent shall
        be equal to the greater of (i) the annual Fixed Rent immediately in
        effect prior to such extension or (ii) an amount an equal to 87.5% of
        the then Fair Market Rental Value of the Premises.

        "Fair Market Rental Value" shall be determined based on the use of the
        Premises as first-class professional space utilizing properties of a
        similar character in comparable first-class office buildings within the
        City of Boston. At least sixty (60) days prior to the last day upon
        which the Tenant may give notice exercising such option Tenant may
        request that Landlord designate the annual Fixed Rent payable in respect
        of the extension period and Landlord shall designate such rent payable
        during the extended term in question within thirty days thereafter but
        Landlord shall not be required to make such designation more than
        seventeen (17) months prior to the commencement of the extended term in
        question. If Tenant disagrees with Landlord's designation then Tenant
        shall have the right in its notice exercising such extension to make a
        request of Landlord for a broker determination (the "Broker
        Determination") of the Fair Market Rental Value for such extended term
        which Broker Determination shall be made in the manner set forth in
        Exhibit D. If Tenant fails timely to request the Broker Determination
        then the term of the Lease shall be extended for the applicable extended
        term and the Fair Market Rent Value for the Premises for such extended
        term shall be equal to that designated by Landlord.

13.23   RIGHT OF FIRST OFFER. If at any time during the term of this Lease while
        the Tenant is not in default under this lease beyond applicable notice
        and/or cure periods and while Tenant itself occupies at least that
        portion of the Premises equivalent to at least 3 floors in either Wing
        One or Wing Two of the Building, additional space of the Building
        devoted to an Office Use shall become available for leasing (this right
        shall not apply to the initial leasing thereof but shall be a so-called
        second generation right), Landlord shall notify Tenant thereof setting
        forth in such notice the terms and conditions upon which Landlord shall
        be willing to lease such space to Tenant and by notice from Tenant to
        Landlord given within ten (10) business days thereafter Tenant may elect
        one of the following:

        (i)     it may accept such offer in which event Landlord and Tenant
                shall enter into an amendment to this Lease adding the
                additional space to the

                                      -55-
<Page>

                Premises demised under this Lease in accordance with the terms
                and conditions offered by Landlord and in the case of space so
                offered which is no more than 5,000 square feet of rentable area
                the offer shall be made for a term which is coterminous with the
                term of this Lease and if more than 5,000 square feet then for a
                term which shall be the longer of the then term remaining under
                this Lease or five years; or

        (ii)    it may reject such offer (and Tenant's failure to respond within
                such ten (10) business day period shall be deemed to be a
                rejection of such offer) in which case Landlord may lease such
                offered space upon such terms and conditions as Landlord shall
                determine; or

        (iii)   it may give to Landlord a counteroffer setting forth the terms
                and conditions upon which Tenant is willing to accept such the
                leasing of such Space and if Tenant makes a counteroffer then
                Landlord may elect to (i) accept such counteroffer in which case
                Landlord and Tenant shall enter into an amendment to this Lease
                adding the additional space to this lease in accordance with the
                terms of such counteroffer or (ii) it may elect to lease such
                space to any third party but upon terms and conditions which are
                not substantially more advantageous to such third party than
                those contained in the Tenant's counteroffer. If the space being
                offered is the V&C premises consisting of approximately 40,000
                square feet of rentable area then Tenant may elect not to lease
                all of the V&C premises but must lease the same in at least
                whole floor increments starting with the top-most floor and
                working down, and in its offer to Tenant, Landlord shall set
                forth the Annual Fixed Rent which Landlord is prepared to accept
                for a leasing of less than all of the offered V&C premises.

                If at the time that Landlord makes an offer to Tenant to lease
                to Tenant any additional space of more than 5,000 square feet
                there is less than five (5) years remaining in the term of this
                Lease, then as a condition to Tenant's acceptance of such offer
                or making a counteroffer, Tenant must exercise any remaining
                option so that there shall be at least five (5) years remaining
                in the term of this Lease and if there are insufficient options
                then Tenant shall have no right to lease the offered space and
                Landlord need not make such offer

                                    EXHIBIT D

                BROKER DETERMINATION OF FAIR MARKET RENTAL VALUE

        DEFINITION OF FAIR MARKET RENTAL VALUE:

        "Fair Market Rental Value" shall be computed as of the date in question,
and shall be the then current annual rental value, including provisions for
subsequent increases and other adjustments, of the Premises in their then
condition, upon and subject to the terms and conditions of this Lease, except
for annual Fixed Rent. In determining Fair Market Rental Value, all relevant
factors shall be taken into account and given effect (the parties agreeing that
any property outside the City of Boston is irrelevant for these purposes).
Tenant's notice shall specify whether Tenant requests a quotation of Fair Market
Rental Value for the Premises "as-is," and/or a quotation of Fair Market Rental
Value including a tenant improvement allowance. If Tenant requests that
Landlord's quotation include a tenant improvement allowance Landlord's quotation
shall include a tenant improvement allowance, in an amount (if any) which is
consistent with Landlord's then current practices and not less than 75% of the
then "market".

        Where in the Lease to which this Exhibit is attached provision is made
for a Broker Determination of Fair Market Rental Value, the following procedures
and requirements shall apply:

        1.      TENANT'S REQUEST. Tenant shall send a notice to Landlord in
                accordance with the applicable section of the Lease, requesting
                a Broker Determination of the Fair Market Rental Value, which
                notice to be effective must (i) make explicit reference to the
                Lease and to the specific section of the Lease pursuant to which
                said request is being made, (ii) include the name of a broker
                selected by Tenant to act for Tenant, which broker shall be
                affiliated with a major Boston commercial real estate brokerage
                firm selected by Tenant and which broker shall have at least ten
                (10) years experience dealing in properties of a nature and type
                generally similar to the Building located in the City of Boston,
                and (iii) explicitly state that Landlord is required to notify
                Tenant within thirty (30) days of an additional broker selected
                by Landlord.

        2.      LANDLORD'S RESPONSE. Within thirty (30) days after Landlord's
                receipt of Tenant's notice requesting the Broker Determination
                and stating the name of the broker selected by Tenant, Landlord
                shall give written notice to Tenant of Landlord's selection of a
                broker having at least the affiliation and experience referred
                to above.

                                       D-1
<Page>

        3.      SELECTION OF THIRD BROKER. Within ten (10) days thereafter the
                two (2) brokers so selected shall select a third such broker
                also having at least the affiliation and experience referred to
                above.

        4.      RENTAL VALUE DETERMINATION. Within thirty (30) days after the
                selection of the third broker, the three (3) brokers so
                selected, by majority opinion, shall make a determination of the
                Fair Market Rental Value of the Premises for the Extended Term
                or the Expansion Space, as the case may be. Such Fair Market
                Rental Value determination (x) may include provision for annual
                increases in rent if so determined, (y) shall take into account
                the as-is condition of the Premises, and (z) shall take account
                of, and be expressed in relation to, the payment in respect of
                taxes and operating costs and provisions for paying for
                so-called tenant electricity as contained in the Lease. The
                brokers shall advise Landlord and Tenant in writing by the
                expiration of said thirty (30) day period of the Fair Market
                Rental Value as so determined.

        5.      RESOLUTION OF BROKER DEADLOCK. If the Brokers are unable to
                agree at least by majority on a determination of Fair Market
                Rental Value, then the brokers shall send a notice to Landlord
                and Tenant by the end of the thirty (30) day period for making
                said determination setting forth their individual determinations
                of Fair Market Rental Value, and the highest such determination
                and the lowest such determination shall be disregarded and the
                remaining determination shall be deemed to be the Fair Market
                Rental Value.

        6.      COSTS. Each party shall pay the costs and expenses of the broker
                selected by it and each shall pay one half (1/2) of the costs
                and expenses of the third broker.

        7.      FAILURE TO SELECT BROKER OR FAILURE OF BROKER TO SERVE. If
                Tenant shall have requested a Broker Determination and Landlord
                shall not have designated a broker within the time period
                provided therefor above and such failure shall continue for more
                than ten (10) days after notice thereof, then Tenant's broker
                shall alone make the determination of the Fair Market Rental
                Value in writing to Landlord and Tenant within thirty (30) days
                after the expiration of Landlord's right to designate a broker
                hereunder. If Tenant and Landlord have both designated brokers
                but the two brokers so designated do not, within a period of ten
                (10) days after the appointment of the second broker, agree upon
                and designate the third broker willing so to act, the Tenant,
                the Landlord or either broker previously designated may request
                the Greater Boston Real Estate Board, Inc. to designate the
                third broker willing so to act and a broker so appointed shall,
                for all purposes, have the same standing and powers as though he
                had been seasonably appointed by the brokers first appointed. In
                case of the inability or refusal

                                       D-2
<Page>

                to serve of any person designated as a broker, or in case any
                broker for any reason ceases to be such, a broker to fill such
                vacancy shall be appointed by the Tenant, the Landlord, the
                brokers first appointed or the said Greater Boston Real Estate
                Board, Inc., as the case may be, whichever made the original
                appointment, or if the person who made the original appointment
                fails to fill such vacancy, upon application of any broker who
                continues to act or by the Landlord or Tenant such vacancy may
                be filled by the said Greater Boston Real Estate Board, Inc.,
                and any broker so appointed to fill such vacancy shall have the
                same standing and powers as though originally appointed.

                                       D-3

                                    EXHIBIT E

        Parking shall be provided on the following floors of the Garage:

        P-1: The entire floor will be for Tenant and V&C for reserved 24/7
spaces. If all of Tenant's 75 reserved 24/7 spaces cannot be accommodated on P-1
together with all of the V&C's reserved 24/7 spaces then Tenant shall have a pro
rata share thereof based on square footage and at least 25 of Tenant's spaces
shall be next to or very near the Wing Two elevator serving the Tenant's
Premises in Wing Two.

        P-2: Any 24/7 reserve not accommodated on P-1 will be accommodated on
P-2 and at least five visitor spaces will be placed next to or very near the
elevators for Wing One.

        P-2 and P-3: The remaining allocation of spaces shall be identified
either as Tenant or V&C spaces and numbered spaces located under each tenant's
respective wings as closely as reasonably possible.

        The allocation of compact to normal size spaces should be the same for
both Tenant and V&C for all spaces on all parking levels and the goal is to have
no more than 30% of all spaces as compact spaces but in any case there shall be
no more than 40% of all spaces as compact spaces.

        Nominal size spaces are being designed to be 8 1/2 feet by 18 feet and
compact size spaces 7 1/2 feet by 16 feet. So long as Tenant leases more than
50% of the office space of the Building, any change in the management company
for the Garage (after the initial manager) shall require Tenant's prior written
consent, which Tenant shall not unreasonably withhold or delay.

                                       E-1

                                    EXHIBIT F

        The air conditioning system shall be designed to provide 20 CFM per
person at one person/150 square feet; for cooling: 78 degrees dry bulb inside at
88 degrees Fahrenheit dry bulb outside; and for heating: 72 degrees Fahrenheit
inside at 9 degrees outside. Landlord represents and warrants that it has been
informed by its engineer that the foregoing standard complies with all
applicable codes.
