                                   SECTION II

                              DESCRIPTION OF CREDIT

        2.1.  THE LOANS.

                (a) Subject to the terms and conditions hereof, the Bank will
make Revolving Loans to the Companies, jointly and severally, from time to time
until the close of business on the Revolving Credit Termination Date, in such
sums as Back Bay, as agent for the Companies, may request, PROVIDED that the
aggregate principal amount of all Loans at any one time outstanding hereunder
shall not exceed the Commitment Amount. The Companies may borrow, prepay
pursuant to Section 2.8 and reborrow, from the date of this Agreement until the
Revolving Credit Termination Date, the full amount of the Commitment Amount or
any lesser sum that is at least $50,000 and an integral multiple of $50,000. Any
Revolving Loan not repaid by the Revolving Credit Termination Date shall be due
and payable on the Revolving Credit Termination Date.

                (b) Subject to the terms hereof, the Bank will lend to the
Companies, jointly and severally, on the Revolving Credit Termination Date, a
Term Loan that shall not exceed, in the aggregate principal amount, the lesser
of (i) the Commitment Amount and (ii) the aggregate principal amount of
Revolving Loans then outstanding (the "TERM LOAN"). The Term Loan shall be
payable in 16 quarterly installments on the last day of each April, July,
October and January of each year, commencing July 31, 2001, with the first 15
installments in an amount equal to the sum of quarterly interest (at the
Applicable Rate), plus quarterly principal in equal amounts sufficient to fully
amortize the Term Loan over forty-eight (48) months, on the Revolving Credit
Termination Date, each, and a final installment payable on the Term Loan
Maturity Date equal to the outstanding balance of the Term Loan, together with
(i) all unpaid interest thereon and all fees and other amounts due hereunder,
and (ii) all amounts due under the Standby Letter of Credit and the Letters of
Credit.

                (c) Provided that no Event of Default shall have occurred and be
continuing, the Companies may convert all or any part (in integral multiples of
$100,000) of any outstanding Loan into a Loan of any other type provided for in
this Agreement in the same aggregate principal amount. Provided that no Event of
Default shall have occurred and be continuing, the Companies may convert all or
any part (in integral multiples of $100,000) of any outstanding LIBOR Loan to an
Alternate Base Rate Loan in the same aggregate principal amount. Any such
conversion shall be on any Business Day (which, in the case of a conversion of a
LIBOR Loan, shall be the last day of the Interest Period applicable to such
LIBOR Loan). Back Bay shall give the Bank prior notice of each such conversion
(which notice shall be effective upon receipt) in accordance with Section 2.2.



                                       11


<PAGE>   16

        2.2. NOTICE AND MANNER OF BORROWING OF LOANS.

                (a) Whenever the Companies desire to obtain or continue a Loan
hereunder or to convert an outstanding Loan into a Loan of another type provided
for in this Agreement, Back Bay, in its capacity as agent for the Companies
shall notify the Bank (which notice shall be irrevocable) by telex, telegraph or
telephone received no later than (i) 10:00 a.m. Boston time on the date which is
one (1) Business Day before the day on which the requested Loan is to be made or
continued as or converted to an Alternate Base Rate Loan, and (ii) 10:00 a.m.
Boston time on the date which is two (2) Business Days before the day on which
the requested Loan is to be made or continued as or converted to a LIBOR Loan.
Such notice shall specify (x) the effective date and amount of each Loan or
portion thereof to be continued or converted, subject to the limitations set
forth in Section 2.1, (y) the pricing option to be applicable thereto, and (z)
the duration of the applicable Interest Period, if any (subject to the
provisions of the definition of Interest Period and Section 2.5(a)). Each such
notification (a "Notice of Borrowing or Conversion") shall be immediately
followed by a written confirmation thereof by Back Bay in substantially the form
of EXHIBIT F attached hereto, PROVIDED that if such written confirmation differs
in any material respect from the action taken by the Bank, the records of the
Bank shall control absent manifest error.

                (b) Subject to all of the terms and conditions hereof and so
long as no Default exists, the Companies may elect to have such portion of the
Loans as Back Bay may specify in the applicable Notice of Borrowing or
Conversion accrue and bear interest during the Interest Period selected in such
Notice of Borrowing or Conversion at the Applicable Rate computed on the basis
of the LIBOR Rate. In the event the Companies at any time fail to elect a LIBOR
Pricing Option under this Section 2.2(b) for any portion of the Loans (upon
initial funding, conversion, termination of a previously elected LIBOR Pricing
Option or otherwise), then such portion of the Loans will accrue and bear
interest at the Applicable Rate based on the Alternate Base Rate. No election of
a LIBOR Pricing Option will become effective if, prior to the commencement of
the applicable Interest Period, the Bank determines that (i) the election or
granting of the LIBOR Pricing Option in question would violate a Legal
Requirement, (ii) LIBOR deposits in an amount comparable to the principal amount
of the Loan as to which such LIBOR Pricing Option has been elected and which
have a term corresponding to the proposed Interest Period applicable to such
Loan are not readily available in the inter-bank LIBOR market, or (iii) by
reason of circumstances affecting the inter-bank LIBOR market, adequate and
reasonable methods do not exist for ascertaining the interest rate applicable to
such deposits for the proposed Interest Period applicable to such Loan. If any
Legal Requirements shall prevent the Bank from funding or maintaining through
the purchase of deposits in the inter-bank LIBOR market any portion of the Loans
subject to a LIBOR Pricing Option or otherwise from giving effect to the Bank's
obligations under this Agreement, the Bank may terminate all of the affected
LIBOR Pricing Options and the portion of the Loans subject to such terminated
LIBOR Pricing Options shall immediately bear interest thereafter at the
Applicable Rate computed on the basis of the Alternate Base Rate.

                (c) Subject to the terms and conditions hereof, the Bank shall
make each Loan on the effective date specified therefor by crediting the amount
of such Loan to the demand deposit account of Back Bay with the Bank.

        2.3. FEES TO THE BANK.

                (a) COMMITMENT FEE. In consideration of the Bank's commitment to
make the extension of credit provided for in this Agreement, the Companies,
jointly and severally, shall pay to the Bank, while such commitment is
outstanding, a commitment fee computed at the rate of one-eighth 




                                       12


<PAGE>   17

of one percent (0.125%) per annum on the Commitment Amount. Such Commitment Fee
shall be payable annually on the Restatement Date and each anniversary thereof.

                (b) UNUSED FACILITY FEE. The Companies, jointly and severally,
shall pay to the Bank during the Revolving Credit Period an unused facility fee
computed at the rate of (i) one quarter of one percent (0.25%) per annum on the
average daily amount of the unborrowed portion of the Commitment Amount during
each quarter or portion thereof, if the Leverage Ratio at the time such fee is
calculated is less than or equal to 2.00 to 1.0, and (ii) one-half of one
percent (0.50%) per annum on the average daily amount of the unborrowed portion
of the Commitment Amount during each quarter or portion thereof if the Leverage
Ratio at the time such fee is calculated is greater than 2.00 to 1.0 and less
than or equal to 4.00 to 1.0. Unused facility fees shall be payable quarterly in
arrears, on the last day of April, July, October and January of each year
beginning July 31, 1998, and on the last day of the Revolving Credit Period.

                (c) LETTER OF CREDIT FEE. The Companies jointly and severally
will pay to the Bank, in arrears, on the last day of April, July, October and
January of each year (commencing on July 31, 1998) until the expiration of the
Letters of Credit, a nonrefundable letter of credit fee for the prior
three-month period, in an amount equal to the product of (i) one-quarter (1/4)
of the then existing per annum Applicable Margin for any LIBOR Loan, times (ii)
the aggregate average daily maximum amount available to be drawn under such
Letters of Credit from time to time during such period, calculated on the basis
of the 360 day year of twelve 30-day months.

                (d) CONTINUED PAYMENT ON DEFAULT. Upon the occurrence and during
the continuance of an Event of Default, the fees due and payable under
subsections (b) and (c) of this Section 2.3 shall continue to be payable at the
rate payable immediately prior to the occurrence of such Event of Default.

        2.4. REDUCTION OF COMMITMENT AMOUNT. Back Bay, as agent for the
Companies may from time to time by written notice delivered to the Bank at least
two Business Days prior to the date of the requested reduction, reduce by
integral multiples of $500,000 any unborrowed portion of the Commitment Amount.
No reduction of the Commitment Amount shall be subject to reinstatement.

        2.5. THE NOTE.

                (a) The Loans shall be evidenced by the Note, executed jointly
and severally by the Companies, payable to the order of the Bank and having a
final maturity of the Term Loan Maturity Date. The Note shall be dated on or
before the date of the first Loan and shall have the blanks therein
appropriately completed.

                (b) The Bank shall, and is hereby irrevocably authorized by the
Companies to, enter on the schedule forming a part of the Note or otherwise in
its records appropriate notations evidencing the date and the amount of each
Loan and the date and amount of each payment of principal made by the Companies
with respect thereto; and in the absence of manifest error, such notations shall
constitute conclusive evidence thereof. The Bank is hereby irrevocably
authorized by the Companies to attach to and make a part of the Note a
continuation of any such schedule as and when required. No failure on the part
of the Bank to make any notation as provided in this subsection (b) shall in any
way affect any Loan or the rights or obligations of the Bank or the Companies
with respect thereto.

        2.6. LETTERS OF CREDIT.

                (a) Subject to all of the terms and conditions of this Agreement
and so long as no Default exists, the Bank will from time to time during the
Revolving Credit Period issue for the account of any of the Companies one or
more standby letters of credit (the "Letters of Credit") in such amounts as may
be required by the Companies; PROVIDED, HOWEVER, that the aggregate face amount
of such Letters of Credit outstanding for the account of all of the Companies at
any time shall not cause the total obligations of the Companies hereunder to
exceed the Commitment Amount. Any Company may from time to time request a Letter
of Credit to be issued by providing notice to the Bank received not less than
three (3) Business Days prior to the requested closing date for such Letter of
Credit specifying (i) the amount of the requested Letter of Credit, (ii) the
beneficiary thereof, (iii) the purpose thereof, and (iv) the requested closing
date therefor. As a condition to the issuance of any Letter of Credit, the
requesting Companies will provide the Bank with a signed application therefor
and will execute such other agreements, documents and instruments relating to
the issuance of Letters of Credit as are customarily required by the Bank.

                (b) Each Letter of Credit and each draft accepted or paid under
a Letter of Credit shall be issued, accepted or paid as the case may be by the
Bank at its Boston office. No Letter of Credit shall provide for the payment of
drafts drawn thereunder, and no draft shall be payable, at a date that is later
than the earlier of (i) the date twelve (12) months after the date of issuance
or (ii) the Revolving Credit Termination Date. Each Letter of Credit and each
draft accepted under a Letter of Credit shall be in such form and minimum
amount, and shall contain such terms, as the Bank and the Companies requesting
such Letter of Credit may agree upon at the time such Letter of Credit is
issued, including a requirement of not less than three (3) Business Days after
presentation of a draft before payment must be made thereunder, the term of such
Letter of Credit and any rights of cancellation with respect thereto.

                (c) At such time as the Bank makes any payment on a draft
presented or accepted under a Letter of Credit, the Companies will pay to the
Bank in immediately available funds on demand the amount of such payment. If the
Companies do not pay to the Bank the amount required by the foregoing provision,
the Bank may in its sole and complete discretion, add the amount of such draft
to the Revolving Credit Loans, and such amount shall be immediately due and
payable on the Revolving Credit Termination Date. It is understood and agreed by
the parties that the issuance of any Letter of Credit hereunder shall result in
a reduction of the Commitment Amount in the face amount of such Letter of Credit
during the period of time such Letter of Credit is outstanding.

        2.7. APPLICATION OF PROCEEDS.

                (a) Subject to Section 2.7(c) and Sections V and VI hereunder,
the Companies will apply the proceeds of the Loans only for working capital,
acquisitions permitted by Section 6.4 hereof, and other lawful corporate
purposes or capital expenditures of the Companies related to the ownership and
operation of the restaurant business thereof.

                (b) Subject to Section 2.7(c) and Sections V and VI hereunder,
Letters of Credit shall be issued only for such lawful corporate purposes as the
Companies have requested in writing and to which the Bank, in its reasonable
discretion, may agree.



                                       14



<PAGE>   19

                (c) None of the Companies will, directly or indirectly, apply
any part of the proceeds of any of the Loans (i) to purchase or carry "Margin
Stock" (as defined in Section 4.11), (ii) to any transaction prohibited by any
laws or regulations applicable to the Bank, or (iii) to effect an acquisition of
the capital stock or assets of any Related Business except as permitted by
Section 6.4.

        2.8. DURATION OF INTEREST PERIODS.

                (a) Subject to the provisions of the definition of Interest
Period, the duration of each Interest Period applicable to a Loan shall be as
specified in the applicable Notice of Borrowing or Conversion. The Companies
shall have the option to elect a subsequent Interest Period to be applicable to
such Loan by Back Bay delivering to the Bank a Notice of Borrowing or Conversion
evidencing such election received no later than 10:00 a.m. Boston time on the
date one (1) Business Day before the end of the then applicable Interest Period
if such Revolving Loan is to be continued as or converted to an Alternate Base
Rate Loan and two (2) Business Days before the end of the then applicable
Interest Period if such Revolving Loan is to be continued as or converted to a
LIBOR Loan.

                (b) If the Bank does not receive a notice of election of
duration of an Interest Period for a LIBOR Loan pursuant to subsection (a) above
within the applicable time limits specified therein, or if, when such notice
must be given, a Default exists, the Companies shall be deemed to have elected
to convert such Loan in whole into an Alternate Base Rate Loan on the last day
of the then current Interest Period with respect thereto.

                (c) Notwithstanding the foregoing, the Companies may not select
an Interest Period that would end, but for the provisions of the definition of
Interest Period, after the Term Loan Maturity Date.

        2.9. INTEREST RATES AND PAYMENTS OF INTEREST. The Loans shall accrue and
bear interest at a rate per annum which shall at all times equal the Applicable
Rate, and such rate shall change contemporaneously with any change in the
Applicable Margin. Interest on each Alternate Base Rate Loan shall be payable in
arrears on the last day of each quarter commencing July 31, 1998, and when such
Loan is due (whether at maturity, by reason of acceleration or otherwise).
Interest on each LIBOR Loan shall be payable for such Interest Period applicable
thereto on the last day thereof and when such Loan is due (whether at maturity,
by reason of acceleration or otherwise). Upon the occurrence and during the
continuance of an Event of Default, the Bank may require accrued interest to be
payable on demand or at regular intervals more frequent than the times set forth
in this Section 2.9.

        2.10. CHANGED CIRCUMSTANCES. In case any change in law, regulation,
treaty or official directive or the interpretation or application thereof by any
court or by any governmental authority charged with the administration thereof
or the compliance with any guideline or request of any central bank or other
governmental authority (whether or not having the force of law):

        (i) subjects the Bank to any tax with respect to payments of principal
interest or any other amounts payable hereunder by the Companies or otherwise
with respect to the transactions contemplated hereby (except for taxes on the
overall net income of the Bank imposed by the United States of America or any
political subdivision thereof); or

        (ii) imposes, modifies or deems applicable any deposit insurance,
reserve, special deposit or similar requirement against assets held by, or
deposits in or for the account of, or loans by, the Bank (other than such
requirements as are already included in the determination of the LIBOR Rate); or


                                       15



<PAGE>   20

        (iii) imposes upon the Bank any other condition with respect to its
performance under this Agreement;

and the result of any of the foregoing is to increase the cost to the Bank,
reduce the income receivable by the Bank or impose any expense upon the Bank
with respect to any Loans, the Bank shall notify the Companies thereof. The
Companies agree to pay to the Bank the amount of such increase in cost,
reduction in income or additional expense as and when such cost, reduction or
expense is incurred or determined, upon presentation by the Bank of a statement
in the amount and setting forth the Bank's calculation thereof, which statement
shall be deemed true and correct absent manifest error.

        2.11. CAPITAL REQUIREMENTS. If after the date hereof the Bank determines
that (i) the adoption of or change in any law, rule, regulation or guideline
regarding capital requirements for banks or bank holding companies, or any
change in the interpretation or application thereof by any governmental
authority charged with the administration thereof, or (ii) compliance by the
Bank or its parent bank holding company with any guideline, request or directive
of any such entity regarding capital adequacy (whether or not having the force
of law), has the effect of reducing the return on the Bank's or such holding
Company's capital as a consequence of the Bank's commitment to make Loans
hereunder to a level below that which the Bank or such holding company could
have achieved but for such adoption, change or compliance (taking into
consideration the Bank's or such holding Company's then existing policies with
respect to capital adequacy and assuming the full utilization of such entity's
capital) by any amount deemed by the Bank to be material, then the Bank shall
notify the Companies thereof. The Companies, jointly and severally, agree to pay
to the Bank the amount of such reduction of the return on the Bank's or such
holding company's capital as and when such reduction is determined, upon
presentation by the Bank of a statement in the amount and setting forth the
Bank's calculation thereof, which statement shall be deemed true and correct
absent manifest error. In determining such amount, the Bank may use any
reasonable averaging and attribution methods.

        2.12. PAYMENTS AND PREPAYMENTS OF THE LOANS. LIBOR Loans may be prepaid
at any time, without premium or penalty, on the last day of any Interest Period
applicable thereto, upon three (3) Business Days' notice. Alternate Base Rate
Loans may be prepaid at any time, without premium or penalty, upon one (1)
Business Day's notice. Any interest accrued on the amounts so prepaid to the
date of such payment must be paid at the time of any such payment. Except as set
forth in Section 2.4 hereof, no prepayment of the Revolving Loans during the
Revolving Credit Period shall affect the Commitment Amount or impair the
Company's right to borrow as set forth in Section 2.1. Prepayments of the Term
Loan shall be applied to installments of principal due thereunder in the inverse
order of maturity.

        2.13. METHOD OF PAYMENT. All payments and prepayments of principal and
all payments of interest shall be made by the Companies to the Bank at 100
Federal Street, Boston, Massachusetts in immediately available funds, on or
before 11:00 a.m. (Boston time) on the due date thereof, free and clear of, and
without any deduction or withholding for, any taxes or other payments. The Bank
may, and each Company hereby authorizes the Bank to, debit the amount of any
payment not made by such time to the demand deposit account of the Companies
with the Bank.

        2.14. ADDITIONAL PAYMENTS. During the continuance of any Event of
Default, the Companies shall pay to the Bank interest on the unpaid principal
balance of the Loans and, to the extent permitted by law, on any overdue
installment of interest and fees or any other amounts payable hereunder or 


                                       16



<PAGE>   21

under the Note, compounded daily and payable on demand, at a rate per annum
equal to one and one-half percent (1.50%) above the then Applicable Rate.

        2.15. PAYMENTS NOT AT END OF INTEREST PERIOD. If the Companies for any
reason make any payment of principal with respect to any LIBOR Loan on any day
other than the last day of an Interest Period applicable to such LIBOR Loan, or
fails to borrow or continue or convert to a LIBOR Loan after giving a Notice of
Borrowing or Conversion Pursuant to Section 2.2, or if any LIBOR Loan is
accelerated pursuant to Section 7.2, the Companies shall pay to the Bank, an
amount computed pursuant to the following formula.

                                      L = (R - T) X P X D
                                          ---------------
                                            360

        L  =    amount payable to the Bank
        R  =    interest rate on such Loan
        T  =    effective interest rate per annum at which any readily 
                marketable bond or other obligation of the United States, 
                selected at the Bank's sole discretion, maturing on or near the 
                last day of the then applicable Interest Period of such Loan and
                in approximately the same amount as such Loan can be purchased 
                by the Bank on the day of such payment of principal or failure 
                to borrow or continue or convert
        P  =    the amount of principal prepaid or the amount of the requested 
                Loan
        D  =    the number of days remaining in the Interest Period as of the 
                date of such payment or the number of days of the requested 
                Interest Period


        The Companies shall pay such amount upon presentation by the Bank of a
statement setting forth the amount and the Bank's calculation thereof pursuant
hereto, which statement shall be deemed true and correct absent manifest error.

        2.16. COMPUTATION OF INTEREST AND FEES. All Interest and fees payable
hereunder shall be computed daily on the days for which due. If the due date of
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 that is not a Business Day such payment may be made on the
next succeeding Business Day (subject to clause 2(i) of the definition of
Interest Period), and such extension shall be included in computing interest in
connection with such payment. The rate of interest payable with respect to Base
Rate Loans shall vary from time to time as the Base Rate varies, and any change
in the rate of interest will become effective on the effective date of a change
in the Base Rate. Interest on Base Rate Loans shall be computed on the basis of
a 360-day year for the actual number of days elapsed.

        2.17. DESIGNATION OF BACK BAY AS AGENT FOR THE COMPANIES. Each Company
hereby irrevocably designates, authorizes, empowers and appoints Back Bay and
such of Back Bay's executive officers as Back Bay shall appoint from time to
time, to act as agent and attorney-in-fact for such Company in connection with
this Agreement, and to execute and deliver any and all notices and other
documents and to perform any and all acts required to be executed, delivered or
performed by such Company hereunder. Each Company agrees that the Bank may rely
upon any notice or other document which purports to be executed or made or which
the Bank in good faith believes to have been executed or made by Back Bay or any
of its executive officers, in its or their capacity as agent for such Company.
Each Company further agrees to indemnify and hold the Bank harmless for any
actions, including the making of each Loan hereunder, and any loss or expense,
taken or incurred by it as a result of the Bank's good faith reliance upon any
such notice or other document.

<PAGE>   24

any other agreement, instrument, order or undertaking binding on any Company, or
