     2.1 The Loans.

          (a) Subject to the terms and conditions hereof, the Lender agrees to
make revolving credit loans (collectively called the "Loans" and individually a
"Loan") to the Borrower from time to time during the period commencing the date
hereof and ending on March __, 1998, or on any earlier date as provided in
Sections 2.6 and 8.1 hereof (the "Revolver Termination Date"), in a principal
amount not to exceed at any time outstanding in the aggregate One Million Eight
Hundred Thousand Dollars - $1,800,000 (the "Revolving Loan Commitment").

          (b) Within the limits of the Revolving Loan Commitment and the
Borrowing Base, the Borrower may borrow, prepay (in accordance with Section 2.7)
and reborrow Loans. All Loans shall, in any event, be repaid by the Borrower on
the Revolver Termination Date.

          (c) The Lender's failure to deliver any bill, statement or invoice
with respect to amounts due under this Agreement shall not affect the Borrower's
obligation to pay any installment of principal, interest or any other amount
under this Agreement when due and payable.

     2.2 The Note. The Loans shall all be evidenced by a single promissory note
of the Borrower (the "Revolving Credit Note") in principal face amount equal to
the Revolving Loan Commitment, payable to the order of the Lender and otherwise
in the form attached hereto as Exhibit A. The Revolving Credit Note shall be
dated the date the first Loan is made and shall bear interest in accordance with
the terms hereof. The Revolving Credit Note shall mature upon the Revolver
Termination Date and, upon maturity, each outstanding Loan shall be due and
payable. The Lender shall maintain records of all Loans evidenced by the
Revolving Credit Note and of all payments thereon, which records shall be
conclusive absent manifest error.

     2.3 Funding Procedures.

          (a) Each request for a Loan shall be made not later than 11:00 a.m. on
a Business Day by delivery to the Lender of a written request signed by the
Borrower, or in the alternative a telephone request followed promptly by written
confirmation of the request, in substantially the form reasonably requested by
the Lender from time to time, including the date and amount of the Loan to be
made. Until such time as the Lender shall reasonably direct the use of a
different form of request, the form of request attached hereto as Exhibit B
shall be used to request the making of Loans. Each request shall be received not
less than two (2) Business Days prior to the date of the proposed borrowing. No
request shall be effective until actually received by the Lender. Upon receipt
by the Lender the request for a Loan shall not be revocable by the Borrower.


                                  Page 5 of 26


          (b) Not later than 11:00 A.M. on the date of each Loan, the Lender
shall make available to the Borrower the amount of such Loan in immediately
available funds.

          (c) If the Lender makes a Loan on a day on which all or any part of an
outstanding Loan is to be repaid, the Lender shall apply the proceeds of the new
Loan to make such repayment and only an amount equal to the difference (if any)
between the amount being borrowed and the amount being repaid shall be made
available by the Lender to the Borrower as provided in paragraph (b).

     2.4 Interest.

          (a) LIBOR. Each Loan shall bear interest on the principal amount
thereof from the date made until such Loan is paid in full, at a rate per annum
initially equal to LIBOR (determined as of the date such Loan is funded) plus
450 basis points. Such rate shall be adjusted by the Lender, based upon LIBOR
determined on the first day of each Interest Period.

          (b) Default Rate.

               (i) If any Event of Default specified in Section 8.1(a) or
Section 8.1(d) shall occur; or

               (ii) If any other Event of Default occurs and the Lender declares
the Note to be immediately due and payable;

THEN, the rate of interest applicable to each Loan then outstanding shall be the
Default Rate. Unless waived by the Lender, the Default Rate shall apply from the
date of the Event of Default until the date such Event of Default or breach is
cured, and interest accruing at the Default Rate shall be payable upon demand.

     2.5 Fees.

          (a) Origination Fee. Upon the execution and delivery of this Agreement
by the Borrower and the Lender, the Borrower shall pay to the Lender a fee (the

or in part, for any reason.

          (b) [OMITTED]

          (c) Early Termination Fee. In the event that the Revolver Termination
Date occurs prior to March 13, 1998 (other than by reason of an Event of
Default described in Section 8.1(d) hereof or a "Termination Event" described in
clauses (vi) - (ix), or (xii), (xiii) of Section 12(b) of the Purchase
Agreement), the Borrower shall pay to the Lender a fee (the "Early

Termination Fee") in immediately available funds, which fee shall be determined

specify in its discretion. Except as otherwise provided herein, all payments of
principal, interest, fees, or other amounts payable by the Borrower hereunder
shall be remitted to the Lender in immediately available funds not later than
11:00 a.m. on the day when due. Whenever any payment is stated as due on a day
