      Section 1.2. Interest Rate.

      (a) Defined Terms. As used in this Section 1.2:

      "Business Day" means a day of the year on which banks are not required or
authorized to close in Cleveland, Ohio and, if the applicable Business Day
relates to any Libor Rate Loan, on which dealings are carried on in the London
interbank Eurodollar market.

      "Interest Period" means, with respect to any Libor Rate Loan, the period
commencing on the date such Loan is made, continued, or converted and ending on
the last day of such period and thereafter, each subsequent period commencing on
the last day of the immediately preceding Interest Period and ending on the last
day of such period. The duration of each Interest Period for any Libor Rate Loan
shall be one month, provided that:

      (i)   whenever the last day of any Interest Period would otherwise occur
            on a day other than a Business Day, the last day of such Interest
            Period shall occur on the next succeeding Business Day; provided
            that if such extension of time would cause the last day of such
            Interest Period for a Libor Rate Loan to occur in the next following
            calendar month, the last day of such Interest Period shall occur on
            the next preceding Business Day;

                                       1
<PAGE>

      (ii)  the Company may not select any Interest Period that both begins
            before and ends after any principal installment payment date set
            forth in Section 1.1(c) above.

      "Libor Rate" means, for any Interest Period for any Libor Rate Loan, an
interest rate per annum equal at all times during such Interest Period to the
quotient of (a) the rate per annum at which deposits in United States dollars
are offered at 11:00 a.m. (London, England time) (or as soon thereafter as is
reasonably practicable) by prime banks in the London interbank eurodollar market
two Business Days prior to the first day of such Interest Period in an amount
and maturity of such Libor Rate Loan, divided by (b) a number equal to 1.00
minus the aggregate (without duplication) of the rates (expressed as a decimal
fraction) of the Libor Reserve Requirements current on the date two Business
Days prior to the first day of such Interest Period.

      "Libor Rate Loan" means any Loan that bears interest with reference to the
Libor Rate.

      "Libor Reserve Requirements" means, for any Interest Period for any Libor
Rate Loan, the maximum reserves (whether basic, supplemental, marginal,
emergency, or otherwise) prescribed by the Board of Governors of the Federal
Reserve System (or any successor) with respect to liabilities or assets
consisting of or including "Eurocurrency Liabilities" (as defined in Regulation
D of the Board of Governors of the Federal Reserve System) having a term equal
to such Interest Period.

      "Prime Rate Loan" means any Loan that bears interest with reference to the
Prime Rate.

      "Prime Rate" of Bank is defined as that rate established from time to time
by the Bank as the Bank's Prime Rate, whether or not such rate is publicly
announced; the Prime Rate may not be the lowest rate charged by Bank for
commercial or other extensions of credit. In the event of any change in the
Prime Rate, the rate of interest upon such Loan shall be adjusted to immediately
correspond with such change, except such interest rate shall not exceed the
highest rate permitted by law.

      (b) Interest Rate. The Loan shall bear interest prior to maturity at a
rate per annum, selected by the Company pursuant to Section 1.2 (d) below, equal
to (i) the Prime Rate minus .50% or (ii) the Libor Rate plus 2.50%.

      (c) Late Payments. Whenever the unpaid principal amount of the Loan(s),
and accrued interest thereon, or any fees or any other sum payable hereunder,
shall become due and payable and remain unpaid (whether by acceleration or
otherwise), the amount thereof shall thereafter until paid in full bear interest
at a rate per annum equal to three percent (3%) in excess of the Prime Rate of
the Bank in effect from time to time, which rate shall change immediately and
correspondingly with each change in the Prime Rate. In addition, prior to
maturity, for each payment of principal or interest not paid when due the
Company shall also pay a late fee equal to $500.00.

      (d) Loan Conversions. The outstanding principal amount of the Loan may be
made or converted into a Prime Rate Loan on such Business Day and in such amount
as the Company shall request by written notice given to the Bank no later than
11:00 a.m. (Cleveland, Ohio time) on the date of disbursement of or conversion
into the requested Prime Rate Loan. Provided that no Event of Default of any
potential default as defined in Section 4.7 below, has occurred and is
continuing, the outstanding principal amount of the Loan may be made or
continued as or

                                       2
<PAGE>

converted into a Libor Rate Loan on such Business Day, in such amount (equal to
$100,000.00 or an integral multiple thereof), and with such an Interest Period
as the Company shall request by written notice given to the Bank no later than
11:00 a.m. (Cleveland, Ohio time) on the second Business Day prior to the date
of disbursement or continuation of or conversion into the requested Libor Rate
Loan. Each written notice of any Libor Rate Loan shall be irrevocable and
binding on the Company and Company shall indemnify the Bank against any loss or
expense incurred by the Bank as a result of any failure by the Company to
consummate such transaction, including, without limitation, any loss (including
loss of anticipated profits) or expense incurred by reason of liquidation or
reemployment of deposits or other funds acquired by the Bank to fund the Loan. A
certificate as to the amount of such loss or expense submitted by the Bank to
the Company shall be conclusive and binding for all purposes, absent manifest
error. The Company may not elect the Libor Rate if U.S. dollar deposits are not
available to the Bank in the London Eurodollar Interbank Market for the period
and in the amount requested by the Company. In the event that the Company fails
to provide the Bank with the required written notice for Libor Rate Loans, the
Company shall be deemed to have given a written notice that such Loan shall be
continued as a Libor Rate Loan on the last day of the applicable Interest Period
for an additional 1 month Interest Period.

      (e) Additional Costs.

            (i) If, due to either (i) the introduction of, or any change in, or
            in the interpretation of, any law or regulation or (ii) the
            compliance with any guideline or request from any central bank or
            other governmental authority (whether or not having the force of
            law), there shall be an increase in the cost to the Bank of making,
            funding or maintaining Loans, then the Company shall from time to
            time, upon demand by the Bank pay to the Bank additional amounts
            sufficient to reimburse the Bank for any such additional costs. A
            certificate of the Bank submitted to the Company as to the amount of
            such additional costs, shall be conclusive and binding for all
            purposes, absent manifest error. Upon notice from the Company to the
            Bank within five (5) Business Days after the Bank notifies the
            Company of any such additional costs pursuant to this Section
            2.8(b), the Company may either (A) prepay in full all Loans of any
            types so affected then outstanding, together with interest accrued
            thereon to the date of such prepayment, or (B) convert all Loans of
            any types so affected then outstanding into Loans of any other type
            not so affected upon not less than four (4) Business Days' notice to
            the Bank. If any such prepayment or conversion of any Libor Rate
            Loan occurs on any day other than the last day of the applicable
            Interest Period for such Loan, the Company also shall pay to the
            Bank such additional amounts sufficient to indemnify the Bank
            against any loss, cost, or expense incurred by the Bank as a result
            of such prepayment or conversion, including, without limitation, any
            loss (including loss of anticipated profits), cost, or expense
            incurred by reason of the liquidation or reemployment of deposits or
            other funds acquired by the Bank to fund any such Loan, and a
            certificate as to the amount of any such loss, cost, or expense
            submitted by the Bank to the Company shall be conclusive and binding
            for all purposes, absent manifest error.

            (ii) If either (i) the introduction of, or any change in, or in the
            interpretation of, any law or regulation or (ii) the compliance with
            any guideline or request from

                                       3
<PAGE>

            any central bank or other governmental authority (whether or not
            having the force of law), affects or would affect the amount of
            capital required or expected to be maintained by the Bank or any
            corporation controlling the Bank and the Bank determines that the
            amount of such capital is increased by or based upon the existence
            of the Loans (or commitment to make the Loans) and other extensions
            of credit (or commitments to extend credit) of similar type, then,
            upon demand by the Bank, the Company shall pay to the Bank from time
            to time as specified by the Bank additional amounts sufficient to
            compensate the Bank in the light of such circumstances, to the
            extent that the Bank reasonably determines such increase in capital
            to be allocable to the existence of the Bank's Loans (or commitment
            to make the Loans). A certificate of the Bank submitted to the
            Company as to such amounts shall be conclusive and binding for all
            purposes, absent manifest error. Upon notice from the Company to the
            Bank within five (5) Business Days after the Bank notifies the
            Company of any such additional costs pursuant to this Section
            2.8(b), the Company may either (A) prepay in full all Loans of any
            types so affected then outstanding, together with interest accrued
            thereon to the date of such prepayment, or (B) convert all Loans of
            any types so affected then outstanding into Loans of any other type
            not so affected upon not less than four (4) Business Days' notice to
            the Bank. If any such prepayment or conversion of any Libor Rate
            Loan occurs on any day other than the last day of the applicable
            Interest Period for such Loan, the Company also shall pay to the
            Bank such additional amounts sufficient to indemnify the Bank
            against any loss, cost, or expense incurred by the Bank as a result
            of such prepayment or conversion, including, without limitation, any
            loss (including loss of anticipated profits), cost, or expense
            incurred by reason of the liquidation or reemployment of deposits or
            other funds acquired by the Bank to fund any such Loan, and a
            certificate as to the amount of any such loss, cost, or expense
            submitted by the Bank to the Company shall be conclusive and binding
            for all purposes, absent manifest error.

      (f) Illegality. Notwithstanding any other provision of this Agreement, if
the introduction of or any change in or in the interpretation of any law or
regulation shall make it unlawful, or any central bank or other governmental
authority shall assert that it is unlawful, for the Bank to perform its
obligations hereunder to make, continue, or convert Libor Rate Loans hereunder,
then, (a) on notice thereof by the Bank to the Company, the obligation of the
Bank to make or continue a Loan of a type so affected or to convert any type of
Loan into a Loan of a type so affected shall terminate and the Bank shall
thereafter be obligated to make Prime Rate Loans whenever any written notice
requests any type of Loans so affected and (b) upon demand therefor by the Bank
to the Company, the Company shall either (i) forthwith prepay in full all Loans
of the type so affected then outstanding, together with interest accrued thereon
or (ii) request that the Bank, upon four (4) Business Days' notice, convert all
Loans of the type so affected then outstanding into Loans of a type not so
affected. If any such prepayment or conversion of any Libor Rate Loan occurs on
any day other than the last day of the applicable Interest Period for such Loan,
the Company also shall pay to the Bank such additional amounts sufficient to
indemnify the Bank against any loss, cost, or expense incurred by the Bank as a
result of such prepayment or conversion, including, without limitation, any loss
(including loss of anticipated profits), cost, or expense incurred by reason of
the liquidation or reemployment of deposits or other funds acquired by the Bank
to fund any such Loan, and a certificate as to the

                                       4
<PAGE>

amount of any such loss, cost, or expense submitted by the Bank to the Company
shall be conclusive and binding for all purposes, absent manifest error.

whole, or in part, in the principal amount of $100,000.00 or any integral

Libor Rate Loan, or any integral multiple thereof only on the last day of the
