2.1 Revolving Loans.

         2.1.1 Advances. Upon the terms and subject to the conditions of this
Agreement, and in reliance upon the representations, warranties and covenants of
the Borrower made herein, the Lender agrees to make loans (each, a "REVOLVING
LOAN" and collectively, the "REVOLVING LOANS") to the Borrower at the Borrower's
request from time to time, from and after the date hereof and prior to the
Revolving Credit Maturity Date, provided that the aggregate principal amount of
Revolving Loans outstanding at any time (after giving


                                      -12-
<PAGE>

effect to all amounts requested), plus the aggregate principal Stated Amount of
Letters of Credit outstanding at such time, plus the aggregate amount of any
unreimbursed draws under outstanding Letters of Credit at such time, shall not
exceed the Revolving Credit Maximum Amount, and provided, further, that at the
time the Borrower requests a Revolving Loan, and after giving effect to the
making thereof, no Default or Event of Default has occurred and is continuing.
The Revolving Credit Loans shall be evidenced by a promissory note of the
Borrower in favor of the Lender in or substantially in the form of Exhibit A-1
hereto (the "REVOLVING CREDIT NOTE"), with appropriate insertions. All requests
for Revolving Loans shall be in the form attached hereto as Exhibit D and shall
be made in such manner as shall be agreed between the Borrower and the Lender,
except that each Revolving Loan shall be in a minimum amount of $100,000 and
shall be in an integral multiple of $100,000, or, if less, the remaining unused
Revolving Credit Maximum Amount.

         2.1.2 Overadvances. The Borrower agrees that it shall be an Event of
Default hereunder if at any time the aggregate amount of Revolving Loans
outstanding (after giving effect to all amounts requested), plus the aggregate
Stated Amount of Letters of Credit outstanding at such time, plus the aggregate
amount of any unreimbursed draws under outstanding Letters of Credit at such
time, shall exceed the Revolving Credit Maximum Amount then in effect, unless
the Borrower, upon notice of such excess from the Lender, immediately, and in
any event within one (1) Business Day, pays cash to the Lender to be credited to
the Loan Account in such amount as shall be necessary to eliminate the excess.

2.2 Term Loan. Subject to the terms and conditions set forth in this Agreement,
the Lender agrees to lend to the Borrower on the Closing Date, and the Borrower
agrees to borrow on such date and repay in accordance with Section 2.3, an
amount equal to the Term Loan Commitment (the "TERM LOAN"). No amounts prepaid
on the Term Loan may be reborrowed. The Term Loan shall be evidenced by separate
promissory note of the Borrower in favor of the Lender in or substantially in
the form of Exhibit A-2 hereto (the "TERM NOTE"), with appropriate insertions.

2.3  Payment and Prepayment of Loans.

         2.3.1 Payment of Revolving Loans. Interest on the Revolving Loans shall
be payable as provided in Section 2.5. On the Revolving Credit Maturity Date,
all outstanding principal of the Revolving Loans, together with all accrued and
unpaid interest thereon, and all fees, charges and expenses relating thereto,
shall be absolutely and unconditionally due and payable in full by the Borrower
to the Lender.

         2.3.2 Payment of Term Loan. Interest on the Term Loan shall be payable
as provided in Section 2.5. The outstanding principal of the Term Loan shall be
amortized in 20 equal installments of $250,000.00 payable on the last day of
each consecutive fiscal quarter of the Borrower commencing with the fiscal
quarter of the Borrower ending nearest to March 31, 2004. If not sooner paid, on
the Term Loan Maturity Date all outstanding principal of the Term Loan, together
with all accrued and unpaid interest


                                      -13-
<PAGE>

thereon, and all fees, charges and expenses relating thereto, shall be
absolutely and unconditionally due and payable in full by the Borrower to the
Lender.

         2.3.3 Method of Payment. All payments and prepayments of principal and
all payments of interest and other amounts shall be made by the Borrower to the
Lender at 100 Federal Street, Boston, Massachusetts 02110, in immediately
available funds, on or before 11:00 a.m. (Boston, Massachusetts time) on the due
date thereof, free and clear of, and without any deduction or withholding for,
any Taxes (excluding any taxes imposed on the net income of the Lender) or other
payments.

         2.3.4 Voluntary Prepayment. Subject to the provisions of Subsection
2.5.2(d), the Borrower may prepay outstanding Loans, or reduce the amount of any
Loan Commitment, in whole or in part at any time without premium or penalty upon
five Business Days' prior written notice to the Lender, provided, however, that
prepayments of the Revolving Loan that do not involve a permanent reduction of
the Revolving Loan Commitment shall not require prior written notice. Amounts so
paid in respect of Revolving Loans (without a reduction in the Revolving Loan
Commitment) may be borrowed and re-borrowed from time to time as provided in
Subsection 2.1.1. Any prepayment of the Term Loan shall constitute a permanent
reduction of the Term Loan and may not be re-borrowed. With respect to the Term
Loan, provided that the Borrower's Maximum Consolidated Leverage Ratio (see
Subsection 5.16(a)) is greater than 1.25 to 1.0 as of the end of the Borrower's
fiscal quarter immediately preceding such prepayment, such voluntary prepayments
of principal shall be applied to installments of principal due in inverse order
of maturity. In all other cases, prepayments will be applied pro rata to reduce
all remaining principal installments of the Term Loan. All reductions of Loan
Commitments, and all prepayments of any Loan, shall be in a minimum amount equal
to $50,000 and in additional increments of $50,000.

         2.3.5 Mandatory Prepayment. To the extent that they exceed the sum of
$400,000 in the aggregate during the term of this Agreement, all proceeds from
(w) the sale of assets by any member of the Borrower Affiliated Group, (x) the
sale of equity interests by any member of the Borrower Affiliated Group (except
to an Affiliate of the Borrower or to another member of the Borrower Affiliated
Group), (y) the issuance of any Indebtedness by any member of the Borrower
Affiliated Group (any such Indebtedness only to be issued in compliance with
Section 5.5), and (z) any insurance proceeds due to any member of the Borrower
Affiliated Group shall be paid to the Lender as permanent reductions of the
principal of the Term Loan. Notwithstanding the foregoing, at any time during
which an Event of Default has occurred and is continuing, all such proceeds
shall be so paid to the Lender as permanent reductions of the principal of the
Term Loan whether or not the aggregate amount of all such proceeds received
during the term of this Agreement exceeds $400,000. Provided that the Borrower's
Maximum Consolidated Leverage Ratio (see Subsection 5.16(a)) is greater than
1.25 to 1.0 as of the end of the Borrower's fiscal quarter immediately preceding
such prepayment, such mandatory prepayments of principal shall be applied to
installments of principal due in inverse order of maturity. In all other cases,
such mandatory prepayments of principal will be applied pro rata to reduce all
remaining principal installments of the Term Loan. Notwithstanding anything


                                      -14-
<PAGE>

to the contrary stated herein, the Borrower shall not be required to pay to the
Lender under this Subsection 2.3.5 any proceeds resulting from (i) insurance
settlements resulting from damage or destruction to restaurant units, provided
that the Borrower provides to the Lender evidence (in form and substance
satisfactory to the Lender in its sole discretion) that such proceeds have been
reinvested in the same or replacement restaurant units within 270 days of the
receipt thereof by the applicable member of the Borrower Affiliated Group, and
(ii) the issuance of equity interests in members of the Borrower Affiliated
Group as part of customary employee option transactions or similar
compensation-related transactions, provided that such issuances are made in the
ordinary course of business and consistent with prior practice.

2.4      Lender's Records of Loan Activity.

         2.4.1 Loan Account. The Lender shall, in its discretion, enter Loans
and advances made by the Lender to the Borrower pursuant to this Agreement
(including, without limitation, on account of Letters of Credit) as debits in
the Loan Account. The Lender shall also record in the Loan Account all payments
made by the Borrower on account of the Loans and may also record therein, in
accordance with customary accounting practices, other debits and credits,
including customary banking charges and all interest, fees, charges and expenses
chargeable to the Borrower under this Agreement. The debit balance of the Loan
Account shall reflect the amount of the Borrower's Obligations hereunder and
shall be considered correct absent manifest error. The Borrower authorizes the
Lender to charge to the Loan Account or to any deposit account which the
Borrower may maintain with the Lender the principal, interest, fees, charges,
taxes and expenses provided for in this Agreement or any other document executed
or delivered in connection herewith.

         2.4.2 Note Schedules. The Lender may, instead of or in addition to
maintaining a Loan Account, and is hereby irrevocably authorized by the Borrower
to, enter on the schedule forming a part of its Notes or otherwise in its
records, appropriate notations (collectively, the "NOTE SCHEDULES") evidencing
the date and the amount of each Loan, as applicable, the interest rate
applicable thereto and the date and amount of each payment of principal made by
the Borrower with respect thereto; and such notations shall be considered
correct absent manifest error. The Lender is hereby irrevocably authorized by
the Borrower to attach to and make a part of its Notes a continuation of any
such schedule as and when required. No failure on the part of the Lender to make
any notation as provided in this Subsection 2.4.2 shall in any way affect any
Loan or the rights of the Lender or the Obligations of the Borrower with respect
thereto.

2.5      Interest.

         2.5.1 Prime Rate Plus Applicable Prime Rate Margin. Subject to the
provisions of Subsection 2.5.2 and Section 2.7, Revolving Loans and the Term
Loan shall each bear interest at a rate per annum equal to the Prime Rate in
effect from time to time, plus the Applicable Prime Rate Margin in effect at
such time. Interest on Revolving Loans and the Term Loan (not at the time
overdue) bearing interest with reference to the Prime Rate


                                      -15-
<PAGE>

shall be payable monthly in arrears on the last Business Day of each month. Any
change in the Prime Rate shall result in a change on the same day in the rate of
interest to accrue from and after such day on the unpaid balance of principal of
Revolving Loans and Term Loan.

         2.5.2 LIBOR Plus Applicable LIBOR Margin.

         (a) At the option of the Borrower, so long as no Default or Event of
Default has occurred and is then continuing, the Borrower may elect from time to
time prior to the Revolving Credit Maturity Date or the Term Loan Maturity Date,
as applicable, to have all or a portion of the unpaid principal amount of any
Loan bear interest during any particular Interest Period by reference to LIBOR;
provided, that any such portion of any Loan shall be in an amount not less than
$250,000 or some greater integral multiple of $250,000 with respect to any
single Interest Period, and provided further, that there shall not be more than
five (5) Loans (or portions thereof) outstanding at any time the interest on
which is determined by reference to LIBOR. Any election by the Borrower to have
interest calculated by reference to LIBOR shall be made by notice (which shall
be irrevocable) to Lender at least three Business Days prior to the first day of
the proposed Interest Period, specifying the LIBOR Amount and the duration of
the proposed Interest Period (which must be for one, two or three months). Any
such election of a LIBOR shall lapse at the end of the expiring Interest Period
unless extended by a further election notice as hereinbefore provided and, in
the event of such lapse, the applicable Loans shall bear interest with reference
to the Prime Rate in accordance with Section 2.5.1. Except as otherwise provided
herein, each LIBOR Amount shall bear interest during each Interest Period
relating thereto at a per annum rate equal to LIBOR plus the Applicable LIBOR
Margin then in effect. Interest on each LIBOR Amount shall be payable on the
last day of each Interest Period relating thereto. Notwithstanding the
foregoing, Borrower may not select an Interest Period which extends beyond the
Revolving Credit Maturity Date for Revolving Loans or the Term Loan Maturity
Date for the Term Loan.

         (b) The Lender shall forthwith upon determining LIBOR provide notice
thereof to the Borrower. Each such notice shall be conclusive and binding upon
the Borrower. If, with respect to any Interest Period, the Lender is unable to
determine LIBOR relating thereto, or adverse or unusual conditions in or changes
in applicable law relating to the applicable London interbank market make it
illegal or, in the reasonable judgment of the Lender, impracticable, to fund
therein the LIBOR Amount or make the projected LIBOR unreflective of the actual
costs of funds therefor to the Lender, or if it shall become unlawful for the
Lender to charge interest on the Loans on a LIBOR basis, then in any of the
foregoing events the Lender shall so notify the Borrower and interest will be
calculated and payable in respect of such projected Interest Period (and
thereafter for so long as the conditions referred to in this sentence shall
continue) by reference to the Prime Rate in accordance with Subsection 2.5.1.

         (c) If any Interest Period would otherwise end on a day which is not a
Business Day for LIBOR purposes, that Interest Period shall end on the Business
Day next


                                      -16-
<PAGE>

preceding or next succeeding such day as determined by the Lender in accordance
with its usual practices and notified to the Borrower at the beginning of such
Interest Period.

         (d) If for any reason any payment or prepayment of principal of a LIBOR
Amount is made on any day other than the last day of an Interest Period, then
the Borrower shall reimburse the Lender for the loss, if any, computed pursuant
to the following formula:

                        L =  (R-T) x P x D + RC
                             -------------
                              360

                        L =  amount of loss to be reimbursed to Lender.

                        R =  LIBOR plus the Applicable LIBOR Margin at the time
                             of the payment.

                        T =  effective interest rate in which United States
                             Treasury bills maturing on the last day of the then
                             current Interest Period and in the same amount as
                             the unpaid principal amount of the Loan can be
                             purchased by Lender on the day of such payment of
                             principal.

                        D =  the number of days remaining in the Interest Period
                             as of the date of such payment.

                        P =  the amount of principal paid.

                        RC = the Reserve Charge due through the date of such
                             payment.

The Borrower shall pay to the Lender the amount of loss, computed in accordance
with the foregoing formula, upon presentation by the Lender of a statement
setting forth the Lender's calculation of the amount of such loss, which notice
shall be conclusive and binding upon the Borrower in the absence of manifest
error.

2.6 Applicable Interest Rate Margins. The "APPLICABLE PRIME RATE MARGIN" and the
"APPLICABLE LIBOR MARGIN" shall, at any given point in time, be determined in
accordance with Table 1 below; provided, however, that from the Closing Date
through the date upon which the Lender first receives the Consolidated balance
sheet and statement of income, retained earnings and cash flow of the Borrower
Affiliated Group for the fiscal quarter ending nearest to June 30, 2004,
together with the CFO Report relating thereto, the level used to determine the
Applicable Prime Rate Margin and the Applicable LIBOR Margin shall be Level II.

</Table>

         For purposes of determining the Applicable Prime Rate Margin and the
Applicable LIBOR Margin, the Maximum Consolidated Leverage Ratio will be tested
quarterly, commencing with the fiscal quarter of the Borrower ending nearest to
June 30, 2004 based on the annual or quarterly financial statements required to
be delivered pursuant to Section 5.1(a) or 5.1(b), respectively. For purposes of
determining the interest rate for any Interest Rate Period hereunder, any
interest rate change shall be effective three Business Days after the date on
which the financial statements required to be delivered pursuant to Section
5.1(a) or Section 5.1(b) are delivered to the Lender, together with the
applicable CFO Report and a notice to the Lender specifying any change in the
Applicable Prime Rate Margin and the Applicable LIBOR Margin. If the Borrower
has failed to deliver the financial statements required to be delivered by it
pursuant to Section 5.1(a) or Section 5.1(b), the Applicable Prime Rate Margin
and the Applicable LIBOR Margin that are then in effect shall automatically be
increased to Level II until such financial statements are delivered.

2.7 Default Interest. Notwithstanding anything to the contrary stated herein,
upon the occurrence and during the continuance of an Event of Default, at the
option of the Lender, to the extent permitted by applicable law, the unpaid
balance of all Loans shall bear interest at a rate equal to (i) in the case of a
non-monetary Event of Default, a rate equal to the Prime Rate plus 2% and (ii)
in the case of a monetary Event of Default, a rate equal to the Prime Rate plus
3%, in either case compounded monthly until such Event of Default is cured or
waived.

2.8 Letters of Credit. Issuance. Upon the terms and subject to the conditions of
this Agreement, and in reliance upon the representations, warranties and
covenants of the Borrower made herein, the Lender agrees to issue upon the
application of the Borrower, to the extent permitted by law and the Uniform
Customs and Practice of the International Chamber of Commerce governing Letters
of Credit (Publication No. 500 or any successor thereto), Letters of Credit
during the period from the date hereof to the 30th day prior to the Revolving
Credit Maturity Date; provided that (i) the aggregate Stated Amount of Letters
of Credit outstanding at any time, plus the aggregate amount of all unreimbursed
draws under such outstanding Letters of Credit shall not at any time exceed
$2,000,000, and (ii) the aggregate principal amount of Revolving Loans
outstanding at such time plus the aggregate principal amount of all Letters of
Credit outstanding at such time, plus the aggregate principal amount of all
unreimbursed draws under outstanding Letters of Credit, shall not exceed the
Revolving Credit Maximum Amount at any time;


                                      -18-
<PAGE>

and provided, further, that at the time Borrower requests the issuance of a
Letter of Credit, and after giving effect to the issuance thereof, no Default or
Event of Default shall have occurred or be continuing. All Letters of Credit
shall have a stated expiration date not to exceed one (1) year and shall, in any
event, expire not later than the 15th day prior to the Revolving Credit Maturity
Date. Amounts drawn under the Letters of Credit shall become immediately due and
payable by the Borrower to the Lender and, if there is availability under the
Revolving Credit Maximum Amount and no Default or Event of Default exists or
would be caused thereby, upon the request of the Borrower, the Lender shall add
the amounts drawn to the Loan Account as Revolving Loans. In order to evidence
such Letters of Credit, the Borrower shall enter into with the Lender such
agreements and execute such instruments and documents as the Lender customarily
requires in like transactions.

2.9 Changed Circumstances.

         2.9.1 Changed Capital Requirements. If, after the date hereof, the
Lender shall have determined that the adoption of any applicable law, rule,
regulation, guideline, directive or request (whether or not having the force of
law) regarding capital requirements for banks or bank holding companies, or any
change therein, or any change in the interpretation or administration thereof by
any governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by the Lender with any
of the foregoing imposes or increases a requirement by the Lender to allocate
capital resources to the Lender's commitment to make Loans which has or would
have the effect of reducing the return on the Lender's capital to a level below
that which the Lender could have achieved (taking into consideration the
Lender's then existing policies with respect to capital adequacy and assuming
full utilization of the Lender's capital) but for such adoption, change or
compliance by any amount deemed by the Lender to be material, then: (i) the
Lender shall promptly after its determination of such occurrence give notice
thereof to the Borrower; and (ii) to the extent that the costs of such increased
capital requirements are not reflected in the then interest rate applicable to
the Loans, the Borrower and the Lender shall thereafter attempt to negotiate in
good faith, within 30 days following the date the Borrower receives such notice,
an adjustment payable hereunder that will adequately compensate the Lender in
light of the circumstances. If the Lender and the Borrower are unable to agree
to such adjustment within 30 days following the date upon which the Borrower
receives such notice, then commencing on the date of such notice (but no earlier
than the effective date of any such increased capital requirement), the fees
payable hereunder shall increase by an amount that will, in the Lender's
reasonable determination, provide adequate compensation. The provisions of this
Section 2.9.1 shall be applied to the Borrower so as not to discriminate against
Borrower vis-a-vis other similarly situated customers of the Lender.

         2.9.2 Other Changes Adverse to Lender. Notwithstanding anything to the
contrary stated herein, if any present or future applicable law (which
expression, as used in this Agreement, includes statutes and rules and
regulations thereunder and interpretations thereof by any competent court or by
any governmental or other


                                      -19-
<PAGE>

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 heretofore or hereafter made upon or otherwise issued
to the Lender by any central bank or other fiscal, monetary or other authority,
whether or not having the force of law) shall (i) subject the Lender to any tax,
levy, impost, duty, charge, fee, deduction or withholding of any nature with
respect to this Agreement, the maximum amount of the Loans or the payment to the
Lender of any amounts due to it hereunder, or (ii) materially change the basis
of taxation of payments to the Lender of the principal or the interest on or any
other amounts payable to the Lender hereunder, or (iii) impose or increase or
render applicable any special or supplemental special deposit or reserve or
similar requirements or assessment against assets held by, or deposits in or for
the account of, or any liabilities of, or loans by an office of the Lender in
respect of the transactions contemplated herein, or (iv) impose on the Lender
any other conditions or requirements with respect to this Agreement, the
Revolving Credit Maximum Amount, any Revolving Loan, the Term Loan Maximum
Amount or the Term Loan and the result of any of the foregoing is (A) to
increase the cost to the Lender of making, funding or maintaining all or any
part of the Loans, or (B) to reduce the amount of principal, interest or other
amount payable to the Lender hereunder, or (C) to require the Lender to make any
payment or to forego any interest or other sum payable hereunder, the amount of
which payment or foregoing interest or other sum is calculated by reference to
the gross amount of any sum receivable or deemed received by the Lender from the
Borrower hereunder, then, and in each such case not otherwise provided for
hereunder, the Borrower will, upon demand made by the Lender accompanied by
calculations thereof in reasonable detail, pay to the Lender such additional
amounts as will be sufficient to compensate the Lender for such additional cost,
reduction, payment or foregoing interest or other sum, provided that the
foregoing provisions of this sentence shall not apply in the case of any
additional cost, reduction, payment or foregoing interest or other sum resulting
from any taxes charged upon or by reference to the overall net income, profits
or gains of the Lender.

2.10 Fees and Charges.

         2.10.1 Unused Commitment Fee. The Borrower shall pay to the Lender a
commitment fee, payable quarterly in arrears on the last Business Day of each
fiscal quarter (or portion thereof) of the Borrower, equal to three-quarters of
one percent (0.75%) per annum of the Average Unused Commitment during such
quarter. In addition, for any quarterly period during which the Averaged Unused
Commitment exceeds 75% of the total available facility, a surcharge equal to an
additional one-quarter of one percent (.25%) per annum of the Average Unused
Commitment shall be payable by the Borrower to the Lender.

         2.10.2 Reserve Charge. The Borrower shall pay to the Lender the Reserve
Charge, if any, with respect to LIBOR Amounts of the Loans outstanding from time
to time on the dates interest is payable on such LIBOR Amounts.

         2.10.3 Letter of Credit Fee. A Letter of Credit fee shall be payable
quarterly on each outstanding standby Letter of Credit at a rate per annum equal
to the Applicable


                                      -20-
<PAGE>

LIBOR Margin applicable to Revolving Loans then in effect multiplied by the
Stated Amount of such Letter of Credit, along with such issuance, documentary
processing and other fees as are customarily charged by Lender on standby
letters of credit. In the event that additional lenders are added to the credit
facility, the Borrower shall, in addition to and not in lieu of any other fees
payable hereunder, pay to the Lender, as the issuing bank, a fronting fee equal
to one-quarter of one percent (0.25%) multiplied by the Stated Amount of each
standby Letter of Credit. Fees assessed under this Subsection 2.10.3 shall be
payable by the Borrower on the last Business Day of each fiscal quarter of the
Borrower during which any Letter of Credit is outstanding.

         2.10.4 Closing Fee. The Borrower shall pay to the Lender a closing fee
equal to one and one-quarter percent (1.25%) multiplied by the sum of (i) the
Revolving Loan Commitment and (ii) the Term Loan Commitment. The closing fee
shall be earned and payable in full to the Lender on the Closing Date.

         2.10.5 Agent's Fee. From and after the date, if any, on which an
additional lender is first added to the credit facilities made available
hereunder, the Borrower shall pay to the Lender, for the Lender's account in its
capacity as agent hereunder, an Agent's Fee of $7,500 per annum for each
additional lender. The Agent's Fee shall be payable quarterly in advance on the
last Business Day of each fiscal quarter of the Borrower.

         2.10.6 Other Customary Charges. The Borrower shall pay to the Lender
any and all reasonable charges customarily made by the Lender against borrowers
generally.

into this Agreement and the other Loan Documents to which it is a party, and
make the Loans hereunder and issue the Letters of Credit, the Borrower hereby
represents, warrants and covenants to the Lender as follows:

properties, income, financial condition, business or prospects of the Borrower
Affiliated Group taken as a whole. Since the date of the Initial Financial
Statement, the Borrower and each other member of the Borrower Affiliated Group
has continued to engage in substantially the same business as that in which it

provisions and has been delivered to the Lender), or constitute a Default or
Event of Default hereunder or (c) result in the creation, other than in favor of
the Lender, of any mortgage, pledge, security interest, lien, encumbrance or
charge upon any of the properties or assets of the Borrower or any other member

the Borrower Affiliated Group are the Leases, the Purchase Documents and the

Loan Documents do not require any consent under or contravene any provision of
any of such Leases, Purchase Documents or Sale Leaseback Documents.

executed and delivered to the Lender by the Borrower. Each of the Loan Documents
to which the Borrower or any other member of the Borrower Affiliated Group is or
is to become a party, when executed and delivered by the Borrower or such other
member of the Borrower Affiliated Group shall constitute a legal, valid and
binding obligation of the Borrower and such other members of the Borrower
Affiliated Group enforceable in accordance with its terms, except as such
enforceability may be limited by (i) applicable bankruptcy, insolvency or
similar laws of general application relating to enforcement of creditors' rights
generally, and (ii) general principles of equity, whether applied in a
proceeding in equity or at law. The execution, delivery and performance of the
Loan Documents and other documents contemplated hereby and thereby, and the
consummation of the transactions contemplated by such Loan Documents and such
other documents, do not require any approval or consent of, or filing or
registration with, any person or entity except the recordation of the Fee and
Leasehold Mortgages, and filings under the Uniform Commercial Code and with the
Patent and Trademark Office, in connection with the Collateral.

3.4 Title to Properties; Absence of Liens. The Borrower and each other member of
the Borrower Affiliated Group has good and marketable title to all of its
properties, assets and rights of every name and nature now purported to be owned
by it, which properties, assets and rights include all those necessary to permit
the Borrower and each other member of the Borrower Affiliated Group to conduct
its business as such business was conducted on the date of the Initial Financial
Statement, free from all liens, charges and


                                      -22-
<PAGE>

encumbrances whatsoever except for insubstantial and immaterial defects in title
in connection with any owned Real Property and except for liens, charges or
encumbrances permitted under Section 5.6.

relating to ERISA or to employee benefit plans generally), and (iii) has
performed all obligations required to be performed by it under, and is not in

agreement, lease, mortgage, note, bond, indenture, license or other instrument
or undertaking to which it is a party or by which any of it or any of its
properties are bound. Neither the Borrower nor any other member of the Borrower
Affiliated Group has received any notice by any governmental authority or third
party with respect to the generation, storage, or disposal or release or threat

statute or regulation.

3.6 Financial Statements. The Borrower has furnished to the Lender the
Consolidated and Consolidating balance sheet of the Borrower Affiliated Group as
of December 31, 2002 and the related Consolidated and Consolidating statements
of earnings and retained earnings and cash flows for the fiscal year then ended
(the "Annual Financials"), which were prepared in accordance with GAAP, and
audited and certified by KPMG, LLP and such financial statements fairly present
the Consolidated and Consolidating financial position of the Borrower Affiliated
Group as at the close of business on such date and the results of its operations
for the fiscal year then ended. The Borrower has also furnished to the Lender
the Consolidated and Consolidating unaudited balance sheet and statement of
income for the Borrower Affiliated Group as at September 30, 2003 and for the
fiscal quarter then ended (together with the Annual Financials, the "INITIAL
FINANCIAL STATEMENT"), which was prepared in accordance with GAAP and certified
by the chief financial officer of the Borrower and such financial statements
fairly present the financial position of the Borrower Affiliated Group as at the
close of business on such date and the results of its operations for the fiscal
quarter then ended, subject only to normal year-end audit adjustments, none of
which will be materially adverse. The Borrower has also furnished to the Lender
the most recent management letter provided to the Borrower by its accountants.
In addition, the Borrower has furnished to the Lender pro forma projections for
the Borrower Affiliated Group (after giving effect to the Harken Acquisition and
the Sale Leaseback) for each calendar year ending December, 2003 through and
including December, 2007, all prepared in accordance with GAAP on a basis
consistent with the financial statements required by Section 5.1. Such
projections were


                                      -23-
<PAGE>

made in good faith and based on assumptions which the Borrower and each member
of the Borrower Affiliated Group believes were reasonable when made. On the date
hereof, neither the Borrower nor any member of the Borrower Affiliated Group has
any Indebtedness or other liabilities (other than trade indebtedness incurred in
the ordinary course of business consistent with past practices), whether
accrued, absolute, contingent or otherwise, and whether due or to become due,
that are not set forth on Exhibit B hereto. Since the date of the Initial
Financial Statement, there have been no material adverse changes, individually
or in the aggregate, in the assets, liabilities, properties, income, financial
condition, business or prospects of any member of the Borrower Affiliated Group,
except as set forth on Exhibit B hereto.

3.7 Events of Default; Solvency. As of the date of this Agreement, no Default or

Borrower Affiliated Group is, or immediately after giving effect to the
consummation of the Loans will be, Insolvent.

has filed all federal, state and other tax returns required to be filed for all
Taxes, and has paid (or has established adequate reserves in accordance with
GAAP for the payment of) all Taxes, assessments and other such governmental
charges due from Borrower or such other member of the Borrower Affiliated Group.
Neither Borrower nor any other member of the Borrower Affiliated Group has
executed any waiver that would have the effect of extending the applicable
statute of limitations in respect of any Tax.

3.9 Labor Relations; Litigation. Neither Borrower nor any other member of the
Borrower Affiliated Group is engaged in any unfair labor practice and, except as
set forth on Exhibit B attached hereto, there is no litigation, proceeding,
governmental investigation (administrative or judicial) or labor dispute,
pending or, to the best knowledge of Borrower and each other member of the
Borrower Affiliated Group, threatened against Borrower or any other member of
the Borrower Group, which, if adversely determined, could have a material
adverse effect on the assets, liabilities, properties, income, financial
condition, business or prospects of the Borrower Affiliated Group taken as a
whole, or on the ability of the Borrower Affiliated Group taken as a whole to
perform its obligations under the Security Documents or under any other
agreement or document contemplated hereby or thereby, nor is any substantial
basis for any such litigation or labor dispute known to exist.

3.10 Dormant Subsidiaries. Each of the Dormant Subsidiaries conducts no business
operations and has no assets or liabilities, except as are specifically
disclosed on Exhibit B attached hereto.

3.11 Contracts with Affiliates, Etc. Except as disclosed on Exhibit B attached
hereto, and except for agreements or transactions (in each case) in the ordinary
course of business and on an arm's-length basis, no member of the Borrower
Affiliated Group is a party to or otherwise bound by any agreements, instruments
or contracts (whether written or oral) with any Affiliate, except for any such
agreement, instrument or contract (other


                                      -24-
<PAGE>

than an agreement, instrument or contract with respect to Indebtedness for
borrowed money) as would not materially and adversely affect the assets,
liabilities, properties, income, financial condition, business or prospects of
such member of the Borrower Affiliated Group.

3.12 Disclosure. No representation or warranty made by the Borrower in this
Agreement, any other Loan Document or in any other agreement, instrument,
document, certificate, statement or letter furnished to the Lender by or on
behalf of the Borrower or any other member of the Borrower Affiliated Group, and
no other factual information heretofore or contemporaneously furnished by or on
behalf of the Borrower or any other member of the Borrower Affiliated Group to
the Lender in connection with any of the transactions contemplated by any of the
Loan Documents contains (as of the date given) any materially untrue statement
of fact or omits to state a fact necessary in order to make the statements
contained therein not misleading in any material respect in light of the
circumstances in which they are made. Except as disclosed herein or in the other
Loan Documents, there is no fact known to any member of the Borrower Affiliated
Group which materially and adversely affects, or which would in the future could
materially adversely affect, the assets, liabilities, properties, income,
financial condition, business or prospects of such member of the Borrower
Affiliated Group.

3.13 Collateral. All of the Obligations of the Borrower and each member of the

6.1 Events of Default. The following shall constitute events of default
(individually, an "EVENT OF DEFAULT"):

         (a) the Borrower shall fail to pay (i) any amount of principal of any
Loans when due or (ii) any amount of interest thereon or any fees or expenses

         (o) (i) any Person or "group" (within the meaning of Section 13(d) of
the Securities Exchange Act of 1934, as amended) of Persons acting in concert as
a partnership or other group shall, as a result of a tender or exchange offer,
open market purchases, privately negotiated purchases or otherwise, have become,

representing 30% or more of the combined voting power of the then outstanding

(within the meaning of Section 13(d) of the Securities Exchange Act of 1934, as
amended) of Persons acting in concert as a partnership or other group shall, as

Exchange Act) of securities of the Borrower representing 35% or more of the
combined


                                      -39-
<PAGE>

voting power of the then outstanding securities of the Borrower ordinarily (and
apart from rights accruing under special circumstances) having the right to vote
in the election of directors; (ii) the board of directors of the Borrower shall

subsequent to the date hereof after having been nominated, or otherwise approved
in writing, by at least a majority of individuals who constituted the board of
directors of the Borrower as of the date hereof; or (iii) any change in equity
ownership of any member of the Borrower Affiliated Group other than the
Borrower, except as may be expressly permitted by Section 5.7; or

         (p) any default or event of default shall occur under any of the Sale
Leaseback Documents.

6.2 Lender's Rights. If an Event of Default shall occur and be continuing, the

or demand, whereupon the same shall become immediately due and payable without
presentment, demand, protest or other notice of any kind, all of which are
hereby waived by the Borrower, (ii) limit, suspend or terminate the Borrower's
right to borrow hereunder, and (iii) exercise any rights and remedies under the
Security Documents and law; provided that in the event of any Event of Default
specified in Subsections 6.1(f) or 6.1(g), all Obligations shall become
immediately due and payable automatically and without any requirement of notice
from the Lender or action by the Lender.


ARTICLE 7. SET OFF; PARTICIPATIONS.

7.1. Right of Set Off. If an Event of Default shall have occurred, and while it
is continuing, any deposits or other sums at any time credited by or due from
the Lender or any entity under the control of Fleet Financial Group, Inc. to the
Borrower may, without demand or notice (any such demand or notice being
expressly waived hereby) and to the fullest extent permitted by law and without
regard to any source of payment whatsoever, at any time be applied to or set off
against Obligations on which the Borrower is primarily liable and may at or
after the maturity thereof be applied to or set off against Obligations on which
the Borrower is secondarily liable, and advice thereof shall thereafter be given
to the Borrower's chief financial officer.

7.2 Rights of Participants. For so long as any Obligation remains outstanding,
the Borrower offers to any financing institution which may consider investing or
participating in the Loans (each such financing institution being referred to in
this subsection as a "PARTICIPANT") the right to rely upon all of the
representations, warranties, covenants and other provisions of this Agreement,
the Notes and the other agreements, instruments and documents referred to herein
or contemplated hereby in making such investment or participation. The Borrower
agrees the decision of any Participant to invest or participate in the Loans
shall constitute an acceptance of such offer and shall make the Participant a
creditor of the Borrower and each other member of


                                      -40-
<PAGE>

the Borrower Affiliated Group. Any Participant may exercise the rights of

Group to such Participant hereunder in accordance with Lender's customary
practice.

CONNECTION WITH OR IN ANY WAY RELATED TO THE LENDER'S RELATIONSHIP WITH THE

CONNECTION WITH, ASSOCIATED WITH OR ANCILLARY TO


                                      -42-
<PAGE>

THIS AGREEMENT, THE SECURITY DOCUMENTS AND THE OTHER DOCUMENTS EXECUTED OR
DELIVERED IN CONNECTION HEREWITH, AND THE ARRANGEMENTS OR TRANSACTIONS
CONTEMPLATED THEREIN, WHETHER OR NOT ALL OR ANY OF THE TRANSACTIONS CONTEMPLATED
BY, ASSOCIATED WITH OR ANCILLARY TO THIS AGREEMENT OR ANY OF SUCH DOCUMENTS ARE
ULTIMATELY CONSUMMATED. WITHOUT PREJUDICE TO THE SURVIVAL OF ANY OTHER COVENANT
OF THE BORROWER HEREUNDER, THE COVENANTS OF THIS SUBSECTION 8.4.2 SHALL SURVIVE
THE TERMINATION OF THIS AGREEMENT AND THE PAYMENT OR SATISFACTION OF PAYMENT OF
AMOUNTS OWING WITH RESPECT TO THE NOTES OR ANY OTHER SECURITY DOCUMENT.

8.5 Amendments, Waivers, Etc. This Agreement, the Notes and the Security
Documents, and any provision hereof or thereof may be waived, discharged or
terminated only by an instrument in writing signed by the Lender and may be
amended only by an instrument in writing signed by both the Borrower and the
Lender.

8.6 Binding Effect of Agreement. This Agreement shall be binding upon and inure
to the benefit of the Borrower and the Lender and their respective successors
and assigns. The Lender shall have the unrestricted right at any time or from
time to time, and without the Borrower's consent, to assign (or participate) all
or any portion of its rights and obligations hereunder to one or more banks or
other financial institutions (each, an "ASSIGNEE"), and the Borrower agrees that
it shall execute, or cause to be executed, such documents, including without
limitation, amendments to this Agreement and to any other documents, instruments
and agreements executed in connection herewith as the Lender shall deem
necessary to effect the foregoing, provided that (i) so long as no Default or
Event of Default has occurred and is continuing, the Lender will make any such
assignment or participation in a minimum amount of $1,000,000 and will get the
Borrower's consent thereto, such consent not to be unreasonably withheld or
delayed (it being agreed that no such consent shall be required in connection
with a pledge of all or any portion of its rights under the Loan Documents to
any of the 12 Federal Reserve Banks organized under Section 4 of the Federal
Reserve Act, 12 U.S.C. Section 341, no such pledge or the enforcement thereof to
release the Lender from its obligations under any of the Loan Documents), and
(ii) with respect to any such participation, the Borrower shall be permitted to
make payments to and otherwise deal solely with the Lender (it being
acknowledged that the participant may have certain voting rights pursuant to the
particular participation arrangement). In addition, at the request of the Lender
and any such Assignee, the Borrower shall issue one or more new promissory
notes, as applicable, to any such Assignee and, if the Lender has retained any
of its rights and obligations hereunder following such assignment, to the
Lender, which new promissory notices shall be issued in replacement of, but not
in discharge of, the liability evidenced by the promissory note held by the
Lender prior to such assignment and shall reflect the amount of the respective
commitments and loans held by such Assignee and the Lender after giving effect
to such assignment. Upon the execution and delivery of appropriate assignment
documentation, amendments and any other documentation required by the Lender in
connection with such assignment, and the payment by the Assignee of the


                                      -43-
<PAGE>

purchase price agreed to by the Lender and such Assignee, such Assignee shall be
a party to this Agreement and shall have all of the rights and obligations of a
Lender hereunder (and under any and all other documents, instruments and
agreements executed in connection herewith) to the extent that such rights and
obligations have been assigned by the Lender pursuant to the assignment
documentation between the Lender and such Assignee, and the Lender shall be
released from its obligations hereunder and thereunder to a corresponding
extent. Without limitation of the foregoing, the Lender may at any time pledge
all or any portion of its rights under the Security Documents including any
portion of either Note to any of the 12 Federal Reserve Banks organized under
Section 4 of the Federal Reserve Act, 12 U.S.C. Section 341. No such pledge or
enforcement thereof shall release the Lender from its obligations under any of
the Security Documents. The Borrower may not assign or transfer its rights or
obligations hereunder.

8.7 Computation of Interest and Fees, Etc. Interest, fees and charges shall be
computed daily on the basis of a year of 360 days and paid for the actual number
of days for which due. If the due date for any payment of principal is extended
by operation of law, interest shall be payable for such extended time. If any
payment required by this Agreement becomes due on a day on which banks in
Boston, Massachusetts are required or permitted by law or an appropriate
authority to remain closed, such payment may be made on the next succeeding day
on which such banks are open, and such extension shall be included in computing
interest in connection with such payment. All payments required of the Borrower
hereunder or under the Notes shall be made in lawful money of the United States
of America in federal or other funds immediately available to the recipient
thereof at the prescribed place of payment.

8.8 Entire Agreement. This Agreement, including the exhibits hereto, sets forth
the entire agreement and understanding of the parties hereto in respect of the
subject matter contained herein, and supersedes all prior agreements, promises,
covenants, arrangements, communications, representations, warranties, whether
oral or written, by any officer, employee or representative of any party hereto.

8.9 Headings. The headings for the sections of this Agreement are for ease of
reference only and are not an integral part of this Agreement. Accordingly, such
headings shall have no relevance to the interpretation of this Agreement.

8.10 Multiple Counterparts. This Agreement may be signed in any number of
counterparts with the same effect as if the signatures hereto and thereto were
upon the same instrument. All such counterparts shall together constitute one
and the same agreement.

8.11 Severability. The provisions of this Agreement are severable, and if any of
these provisions shall be held by any court of competent jurisdiction to be
unenforceable, such holdings shall not affect or impair any other provision
hereof.

8.12 WAIVER OF JURY TRIAL. EACH OF THE BORROWER AND THE LENDER HEREBY KNOWINGLY,
VOLUNTARILY AND INTENTIONALLY


                                      -44-
<PAGE>

WAIVE THE RIGHT TO A TRIAL BY JURY IN RESPECT OF ANY CLAIM BASED HEREON, ARISING
OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER LOAN DOCUMENTS
CONTEMPLATED TO BE EXECUTED IN CONNECTION HEREWITH OR ANY COURSE OF CONDUCT,
COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY
PARTY HERETO. THIS WAIVER CONSTITUTES A MATERIAL INDUCEMENT FOR LENDER TO
EXECUTE THIS AGREEMENT AND MAKE THE LOANS.

8.13. WAIVER OF SPECIAL DAMAGES. EXCEPT AS PROHIBITED BY LAW, THE BORROWER
HEREBY WAIVES ANY RIGHTS WHICH IT MAY HAVE TO CLAIM OR RECOVER IN ANY LITIGATION
WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION
WITH THE SECURITY DOCUMENTS, INCLUDING WITHOUT LIMITATION THIS AGREEMENT, THE
NOTE AND THE OTHER SECURITY DOCUMENTS AND ANY AMENDMENTS THEREOF, ANY SPECIAL
EXEMPLARY OR PUNITIVE DAMAGES. THE BORROWER (A) CERTIFIES THAT NEITHER THE
LENDER NOR ANY REPRESENTATIVE, AGENT OR ATTORNEY THEREOF HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT THE LENDER WOULD NOT, IN THE EVENT OF LITIGATION,
SEEK TO ENFORCE THE FOREGOING WAIVERS AND (B) ACKNOWLEDGES THAT, IN ENTERING
INTO THIS AGREEMENT, THE LENDER IS RELYING UPON, AMONG OTHER THINGS, THE WAIVERS
AND CERTIFICATIONS CONTAINED IN THIS SECTION 8.13.

8.14. Usury. All agreements between the Borrower and the Lender are hereby
expressly limited so that in no contingency or event whatsoever, whether by
reason of acceleration of maturity of the indebtedness evidenced hereby or
otherwise, shall the amount paid or agreed to be paid to the Lender for the use
or the forbearance of the indebtedness evidenced hereby exceed the maximum
permissible under applicable law. As used herein, the term "applicable law"
shall mean the law in effect as of the date hereof provided, however, that in
the event there is a change in the law which results in a higher permissible
rate of interest then the Revolving Credit Note and the Term Note shall be
governed by such new law as of its effective date. In this regard, it is
expressly agreed that it is the intent of the Borrower and the Lender in the
execution, delivery and acceptance of the Revolving Credit Note and the Term
Note to contract in strict compliance with the laws of the Commonwealth of
Massachusetts from time to time in effect. If, under or from any circumstances
whatsoever, fulfillment of any provision hereof or of any of the Loan Documents
at the time of performance of such provision shall be due, shall involve
transcending the limit of such validity prescribed by applicable law, then the
obligation to be fulfilled shall automatically be reduced to the limits of such
validity, and if under or from circumstances whatsoever the Lender should ever
receive as interest an amount which would exceed the highest lawful rate, such
amount which would be excessive interest shall be applied to the reduction of
the principal balance evidenced hereby and not to the payment of interest. This
provision shall control every other provision of all agreements between the
Borrower and the Lender.

                                      -45-
<PAGE>

8.15 Replacement of Notes and Other Loan Documents. Upon receipt of an affidavit
of an officer of the Lender as to the loss, theft, destruction or mutilation of
the Revolving Credit Note, the Term Note, or any other Security Document which
is not of public record, and, in the case of any such loss, theft, destruction
or mutilation, upon cancellation of such Revolving Credit Note, Term Note or
other Security Document, and execution and delivery of an appropriate
indemnification agreement by the Bank in favor of the Borrower relating thereto,
the Borrower will issue, in lieu thereof, a replacement Revolving Credit Note,
