                    --------- 

          2.1  Commitment to Lend.
               ------------------ 

               (a) During the Term of this Agreement the Lender agrees, on the
terms and conditions contained in this Agreement, to make Loans to the Borrower
at any time prior to the Termination Date in an aggregate amount not exceeding
at any one time outstanding the Commitment in effect at the time the Loans are
made. The Borrower shall repay Loans in accordance with Section 2.3 and may
reborrow under this Section 2.1(a) at any time.

               (b) Any other provision of this Agreement to the contrary
notwithstanding, the Lender shall not be obligated to make a Loan to the
Borrower at any time that the Borrower is, or after giving effect to the making
of the Loan the Borrower would be, in violation of (i) any of the terms,
conditions, covenants or provisions of this Agreement including, without
limitation, the terms and conditions contained in Section 3 hereof or (ii) any
of the terms, conditions, covenants or provisions of the Cash Management
Agreement.

               (c) The commitment of the Lender to make Loans to the Borrower
set forth in Section 2.1 (a) may be cancelled by the Lender at any time after
the first anniversary of the date of this Agreement. The Lender shall give the
Borrower not less than 120 days' prior written notice of cancellation of the
Commitment (which notice can be given up to 120 days prior to the first
anniversary).

          2.2  Method of Borrowing.
               ------------------- 

               (a) With respect to each Loan made pursuant to Section 2.1
hereof, except as provided in paragraph (c) below, the Borrower shall give the
Lender a notice of borrowing notifying the Lender of its request to borrow
hereunder which notice will specify (i) the date of the Loan, which date shall
be a Business Day, (ii) whether the Loan will be a Base Rate Loan or a LIBOR
Loan, (iii) the principal amount of the Loan, which in the case of a LIBOR Loan
shall be $500,000 or a greater multiple thereof, and (iv) in the case of a LIBOR
Loan, the duration thereof which shall be one, two

                                      -10-
<PAGE>
 
or three months, subject to the provisions of paragraph (d) below.  The notice
of borrowing shall be written, provided that it may be given orally (to be
confirmed in writing if the Lender so requests) if the principal amount of the
Loan is less than $500,000.

          (b) If the Borrower gives the notice required by Section 2.2(a) with
respect to any Loan before 1:00 p.m. (Eastern Time), the Lender will disburse
the proceeds of the Loan to the Borrower in immediately available funds on the
Business Day following the date of such notice.  The Lender will disburse all
Loans to the Borrower by deposit in the Concentration Account (as that term is
defined in the Cash Management Agreement) or, if the Cash Management Agreement
shall no longer be in effect, by deposit in such account as shall be designated
by the Borrower in the applicable notice of borrowing.

          (c) On any Business Day that there would be outstanding (if not for
the limitation as to the principal amount of advances set forth in Section 5(c)
of the Cash Management Agreement) advances from the Lender to the Borrower under
the Cash Management Agreement in an aggregate amount (the "Covered Amount") that
is greater than $2.0 million, the Borrower shall be deemed to have given the
Lender a notice of borrowing requesting a Loan hereunder.  The principal amount
of the Loan so requested shall be the amount by which the Covered Amount exceeds
$2.0 million.  The Lender will make the proceeds thereof available to the
Borrower on the day the Borrower is deemed to give such notice.  Each Loan made
pursuant to this paragraph (c) shall be a Base Rate Loan.

          (d) If in any notice of borrowing given pursuant to paragraph (a)
above the Borrower designates a period of duration for a LIBOR Loan which would
otherwise end on a day which is not a Business Day, that period shall end on the
next preceding Business Day.  Any such period of duration which begins prior to
the Termination Date and would otherwise end after the Termination Date shall
end on the Termination Date.

          2.3  Repayment and Prepayment of the Loans.
               ------------------------------------- 

               (a) The Borrower agrees that it shall repay each LIBOR Loan at
the end of the period of duration applicable thereto and it shall repay all
Loans no later than the Termination Date.

               (b) The Lender may, in its sole discretion, set off any amounts
due and owing to it by the Borrower hereunder (and not otherwise paid by the
Borrower) against amounts owed by the Lender to the Borrower as provided in
Section 8.8.

               (c) The Borrower may repay or prepay the outstanding principal
amount of Loans in whole or in part on any Business Day upon irrevocable notice
to the Lender given not later than 1:00 p.m. (Eastern Time) on the Business Day
prior to the proposed payment date, provided, however, that the Borrower may
make repayments pursuant to Section 4(a) of the Cash Management

                                      -11-
<PAGE>
 
Agreement without giving such notice.  Notice hereunder shall specify the date
of the repayment or prepayment, the principal amount to be repaid or prepaid
(which amount, in the case of a LIBOR Loan, shall be a multiple of $500,000) and
whether such payment relates to Base Rate Loans or LIBOR Loans and, if the
latter, identifying the LIBOR Loan or Loans to which such payment applies.  Each
such repayment or prepayment shall be made on the dates specified and shall be
accompanied by payment of all accrued interest thereon and, subject to
compliance with the foregoing procedures, may be made at any time without cost
or penalty of any kind; provided, however, that, if the Borrower prepays any
LIBOR Loan in whole or in part, the accrued interest on the principal amount to
be prepaid will be recalculated from the date the applicable LIBOR Loan was
borrowed as if that amount had been borrowed as a Base Rate Loan.

          (d) Subject to the conditions of Section 2.2(a) and this Section
2.3(d), a LIBOR Loan may, on the last day of the applicable period of duration
thereof, be converted into a Base Rate Loan or a new LIBOR Loan and a Base Rate
Loan may, on any Business Day, be converted into a LIBOR Loan.  The applicable
notice of borrowing given pursuant to Section 2.2(a) shall designate any part of
the Loan requested thereby that is to be made by conversion of an existing Loan
rather than by advancing a new Loan.  To the extent that a Loan is made by
conversion of an existing Loan, the conditions of lending set forth in Section
3.1 hereof will not apply.  Notwithstanding the provisions of this Section
2.3(d), during a Default the Lender may notify the Borrower that Base Rate Loans
may not be converted into LIBOR Loans and that LIBOR Loans may not be converted
into new LIBOR Loans.

          2.4  Evidence of the Loans.
               --------------------- 

               (a) The Loans made to the Borrower shall be evidenced by this
Agreement and by a loan account in the Borrower's name to be maintained by the
Lender.  All Loans shall be payable by the Borrower to the order of the Lender
not later than the Termination Date.

               (b) The Lender's loan account shall reflect appropriate notations
evidencing the date, the amount and the maturity of each Loan and the date and
amount of each payment of principal made by the Borrower with respect thereto.
The loan account shall be conclusive evidence, absent manifest error, of the
amount of the Loans, the interest accrued and payable thereon and all interest
and principal payments made thereon. Any failure to record or any error therein
shall in no way limit or otherwise affect the obligations of the Borrower
hereunder to pay any amount owing with respect to the Loans.

          2.5  Interest Rates and Payments.  (a) Base Rate Loans shall bear
               ---------------------------                                 
interest on the outstanding principal amount thereof at a rate per annum equal

writing, not later than ten days after the end of each month, of the amount of
interest payable hereunder with respect to Base Rate Loans which notice will set
forth in reasonable detail the calculation of such amount.  The Borrower agrees
that it shall pay each monthly installment of interest within five Business Days
of the date on which it receives such notice.

          (b) LIBOR Loans shall bear interest on the outstanding principal
amount thereof, for the applicable duration thereof as selected by the Borrower
in the notice of borrowing given pursuant to Section 2.2(a), at a rate per annum
equal to LIBOR for such period as in effect one Business Day before the
beginning of the period plus 1% (one percent).  Interest on LIBOR Loans shall be
payable, and the Borrower agrees that it shall pay such interest without any
requirement of notice from the Lender, with respect to the period of duration of
each LIBOR Loan on the last day thereof.

          (c) Overdue principal of and, to the extent permitted by law, overdue
interest on the Loans shall bear interest, payable on demand of the Lender, for
each day until paid at a rate per annum equal to the Base Rate  plus 2% (two
percent).

          2.6  Commitment Fee.  During the Term of this Agreement, the Borrower
               --------------                                                  
shall pay to the Lender a commitment fee computed at a rate per annum equal to
0.35% on the unused amount of the Commitment.  Such commitment fee shall accrue

September and December, of the amount of the commitment fee payable hereunder.
The Borrower agrees that it shall pay the commitment fee within five Business
Days of the date on which it receives such notice.

          2.7  Reduction and Cancellation of the Commitment.  (a) The Borrower
               --------------------------------------------                   
shall have the right, after the first anniversary of the date of this Agreement,
upon at least 120 days' prior written notice (which notice can be given up to
120 days prior to the first anniversary) to the Lender, to terminate or reduce
the unused portion of the Commitment.  Any such reduction of the Aggregate
Commitment shall be in the minimum amount of $500,000 or a greater multiple
thereof (except that any such reduction may be in the full amount of the unused
portion of the Commitment).  The accrued commitment fee with respect to the
terminated or reduced portion of the Aggregate Commitment shall be payable on
the effective date of such reduction or termination.

          (b) The Commitment shall terminate on the Termination Date, and any
Loans then outstanding (together with accrued interest thereon) shall be repaid
in full on such date.
