on the Telerate page 3750 as of 11:00 a.m. London time on the day that is two
London Banking Days preceding the first day of such LIBOR Rate Loan; provided,
however, if the rate described above does not appear on the Telerate System on
any applicable interest determination date, the LIBOR rate shall be the rate
(rounded upwards as described above, if necessary) for deposits in dollars for a
period substantially equal to the interest period on the Reuters Page "LIBO" (or

(2) London Banking Days prior to the beginning of such interest period.

<PAGE>

"Banking Day" shall mean, in respect of any city, any date on which commercial
banks are open for business in that city.

          If both the Telerate and Reuters system are unavailable, then the rate
for that date will be determined on the basis of the offered rates for deposits
in U.S. dollars for a period of time comparable to such LIBOR Rate Loan which
are offered by four major banks in the London interbank market at approximately
11:00 a.m. London time, on the day that is two (2) London Banking Days preceding
the first day of such LIBOR Rate Loan as selected by the Bank. The principal
London office of each of the four major London banks will be requested to
provide a quotation of its U.S. dollar deposit offered rate. If at least two
such quotations are provided, the rate for that date will be the arithmetic mean
of the quotations. If fewer than two quotations are provided as requested, the
rate for that date will be determined on the basis of the rates quoted for loans
in U.S. dollars to leading European banks for a period of time comparable to
such LIBOR Rate Loan offered by major banks in New York City at approximately
11:00 a.m. New York City time, on the day that is two London Banking Days
preceding the first day of such LIBOR Rate Loan. In the event that the Bank is
unable to obtain any such quotation as provided above, it will be deemed that
LIBOR pursuant to a LIBOR Rate Loan cannot be determined. In the event that the
Board of Governors of the Federal Reserve System shall impose a Reserve
Percentage with respect to LIBOR deposits of the Bank, then for any period
during which such Reserve Percentage shall apply, LIBOR shall be equal to the
amount determined above divided by an amount equal to 1 minus the Reserve
Percentage. "Reserve Percentage" shall mean the maximum aggregate reserve

which is imposed on member banks of the Federal Reserve System against "Euro-
currency Liabilities" as defined in Regulation D.

                                 -------------------------

      2.1 Loans:  Subject to the terms and conditions of this Agreement, the
          -----
Bank agrees to make Loans to the Company, whether Advances or Term Loans, as
provided for herein.

      2.2 Revolving Credit Commitment:  Subject to the terms and conditions
          ---------------------------
hereof, the Bank agrees to extend credit to the Company (a) by making loans
(each such loan being hereinafter called an "Advance") to the Company from time
to time during the Revolving Credit Commitment Period or (b) by issuing Letters
of Credit for the Company up to an aggregate stated amount at any one time
outstanding of Two Hundred Thousand and 00/100 ($200,000.00) Dollars pursuant to
Section 2.14 hereof during the Revolving Credit Commitment Period provided that
at any time the sum of (i) the aggregate principal amount of the Advances plus
(ii) the aggregate stated amount of the Letters of Credit shall not exceed at
any one time outstanding Six Million and 00/100 ($6,000,000.00) Dollars (the
"Revolving Credit Commitment").  During the Revolving Credit

                                      -8-
<PAGE>

Commitment Period, the Company may use the Revolving Credit Commitment by
borrowing, paying and prepaying in whole or in part and reborrowing, in
accordance with the terms and conditions hereof.

      2.3 Revolving Credit Note:  The Advances made by the Bank pursuant to
          ---------------------
Section 2.2 hereof shall be evidenced by a promissory note of the Company,
payable to the order of the Bank, substantially in the form of Exhibit A hereto,
with blanks appropriately completed (the "Revolving Credit Note") representing
the obligation of the Company to pay the lesser of (a) the Revolving Credit
Commitment or, (b) the aggregate unpaid amount of all Advances made by the Bank
plus interest. The Revolving Credit Note shall bear interest on the unpaid
principal balance thereof from time to time outstanding at a rate per annum to
be elected by the Company in accordance with the notice provisions set forth in
Section 2.4 hereof, and in the case of LIBOR Rate Loans for the Interest Periods
of one, two, three or six months as therein specified, equal to either (1) the
LIBOR Rate plus 1.50%, or (2) the Prime Rate (which interest rate will change
when and as the Prime Rate changes). In all cases interest shall be computed on
the basis of a 360-day year for actual days elapsed and shall be payable as
provided in Section 2.8(a) hereof. After any stated or accelerated maturity, the
Revolving Credit Note shall bear interest at the Post Default Rate. The
Revolving Credit Note shall be dated the date of this Agreement, be payable to
the order of the Bank and be stated to mature on the Termination Date. The Bank
is hereby irrevocably authorized by the Company to enter on the schedule
attached to the Revolving Credit Note the amount of each Advance made by it,
each payment thereon, and the other information provided for on such schedule;
provided, however, that the failure to make any such entry with respect to any
Advance shall not limit or otherwise affect the obligation of the Company to
repay the same and, in all events, the principal amount owing by the Company in
respect to the Revolving Credit Note shall be the aggregate amount of all
Advances made by the Bank less all payments of principal thereon made by the
Company. The Bank may attach one or more continuations to such schedule as and
when required. The aggregate unpaid principal balance of the Advances set forth
on the schedule attached to its Revolving Credit Note shall be presumptive
evidence of the principal amount owing and paid thereon.

      2.4   Procedure for Borrowing:  The Company may borrow under the Revolving
            -----------------------
Credit Commitment during the Revolving Credit Commitment Period on any Business
Day by giving the Bank irrevocable notice of a request for an Advance hereunder
at least one (1) Business Day but no more than four (4) Business Days before a
proposed borrowing, or at least three (3) Business Days but no more than four
(4) Business Days if the Advance will be a LIBOR Rate Loan, or continuation,
setting forth (i) the amount of the Loan request, which shall, in the case of
LIBOR Rate Loans, not be less than Two

                                      -9-
<PAGE>

Hundred Fifty Thousand ($250,000.00) Dollars and integral multiples of One
Hundred Thousand ($100,000.00) Dollars in excess thereof, and, in the case of
Fluctuating Rate Loans, not be less than One Hundred Thousand ($100,000.00)
Dollars and integral multiples of One Hundred Thousand ($100,000.00) Dollars in
excess thereof, (ii) whether the Advance shall be a Fluctuating Rate Loan or a
LIBOR Rate Loan, (iii) the requested Interest Period commencement date, and (iv)
the length of the Interest Period therefor which shall not extend beyond the
Termination Date. Such notice shall be written (including, without limitation,
via facsimile transmission) and shall be sufficient if received by 1:00 p.m. on
the date on which such notice is to be given. Unless notification is otherwise
furnished by the Company to the Bank (in a manner consistent with the
requirements of this Section 2.4), Loans will be made by credits to the
Company's demand deposit account maintained with the Bank upon compliance with
the requirements of this Agreement. If the Company furnishes such notice but no
election is made as to the Interest Period to be applicable thereto, the Loan
will automatically then be made as a Fluctuating Rate Loan until such required
information is furnished pursuant to the terms hereof.

      2.5 Term Loan:  Subject to the terms and conditions hereof, the Bank
          ---------
agrees to make a term loan (the "Term Loan") to the Company on the date hereof
in the principal amount of $449,973.00.  The Term Loan shall bear interest at a
rate per annum to be elected by the Borrower at closing and continued or
converted in accordance with the requirements of Section 2.7 hereof, equal to
(y) the Prime Rate in effect from time to time or (z) the LIBOR Rate for a one
month Interest Period plus 1.50% which, at the Company's option, may be swapped
into a fixed rate equivalent in accordance with the Master Agreement.

      2.6 Term Note:  The Term Loan shall be evidenced by a promissory note of
          ---------
the Company substantially in the form of Exhibit B hereto with appropriate
insertions (the "Term Note") payable to the order of the Bank and dated the date
of the Term Loan.  The principal amount of the Term Note shall be payable in
twenty-one (21) consecutive monthly installments, the first twenty (20) of which
shall be in an amount equal to $21,429.00 each, and the final installment to be
in the amount equal to the then unpaid principal balance, payable on the first
day of each month commencing March 1, 2000 until November 1, 2001 when the
entire unpaid principal balance of the Term Note together with all interest
accrued and unpaid shall be paid in full.  In all cases, interest shall be
computed on the basis of a 360 day year for actual days elapsed and shall be
payable as provided in Section 2.8(a) hereof.  After any stated or accelerated
maturity thereof, the Term Note shall bear interest at the Post Default Rate.

                                      -10-
<PAGE>

      2.7 Continuation and Conversion of Loans:  The Company shall have the
          ------------------------------------
right at any time on prior irrevocable written notice to the Bank (i) to
continue any Loan into a subsequent Interest Period and (ii) to convert any Loan
into another type of Loan permitted by this Agreement (specifying, in the case
of LIBOR Rate Loan, the Interest Period to be applicable thereto), subject to
the following:

          (a)  in the case of a conversion of less than all of the outstanding
Loans, the aggregate principal amount of Loans converted shall not be less than
the minimum amounts and multiples thereof specified in Section 2.4 hereof; and

          (b)  no Loan (other than a Fluctuating Rate Loan) shall be converted
at any time other than at the end of an Interest Period applicable thereto.

     In the event that the Company shall not give notice to continue a Loan into
a subsequent Interest Period, such Loan (unless prepaid) shall automatically be
converted into a Fluctuating Rate Loan.  The Interest Period resulting from a
conversion shall be specified by the Company in the irrevocable notice delivered
by the Company pursuant to this Section and Section 2.4 hereof; provided,
                                                                --------
however, that, if such notice does not specify the Interest Period to be
-------
applicable thereto, the Loan shall automatically be converted into, or continued
as, as the case may be, a Fluctuating Rate Loan until such required information
is furnished pursuant to the terms hereof. Notwithstanding anything to the
contrary contained above, if an Event of Default shall have occurred and is
continuing, no Loan may be continued into a subsequent Interest Period and no
Fluctuating Rate Loan may be converted into a Fixed Rate Loan.

      2.8 Payments:
          --------

          (a)  Interest accrued on each Loan shall be payable, in arrears
without duplication, on:

          (i)   the Maturity Date of such Loan (excluding any Installment
Payment Date unless interest would otherwise be payable on such Installment
Payment Date pursuant to subsections (ii) - (vi) below);

          (ii)  with respect to any portion of any Loan repaid or prepaid
pursuant to this Agreement, the date of such repayment or prepayment, as the
case may be;

          (iii) the first day of each month, commencing with the first
such date following the date of the making of the Loans; and

                                      -11-
<PAGE>

          (iv)  with respect to that portion of the outstanding principal amount
converted into Fluctuating Rate Loans or Fixed Rate Loans on a day when interest
would not otherwise have been payable pursuant to Section 2.8(a)(iii), the date
of such conversion.

          (b)  All payments (including prepayments) to be made by the Company on
account of principal or interest with respect to any Loan or on account of fees
or any other obligations of the Company to the Bank hereunder shall be charged
to a demand deposit account maintained by the Borrower with the Bank.  If any
payment to be so made hereunder, or under a Note, becomes due and payable on a
day other than a Business Day, such payment shall be extended to the next
succeeding Business Day and, to the extent permitted by applicable law, interest
thereon shall be payable at the then applicable rate during such extension.

          (c)  If the entire amount of any required principal and/or interest
payment is not paid in full within ten (10) days after the same is due, the
Company shall pay to the Bank a late fee equal to three (3%) percent of the
required payment.

      2.9 Interest:  (a) The Company shall give irrevocable written notice
          --------
to the Bank of its election of interest rate options upon the time period set
forth in and containing the information required by Section 2.4 hereof.

          (b)  The interest rate applicable to the Note, while a fluctuating
rate is in effect, shall change when and as the Prime Rate is changed, and any
such change in the Prime Rate shall become effective on the day on which such
change is adopted.

          (c)  Interest on the Loans shall be computed on the basis of a year of
three hundred sixty (360) days for actual days elapsed (including the first but
excluding the last) occurring in the period for which payable.

          (d)  If all or a portion of the principal or interest of any Loan
shall not be paid when due (whether at the stated or any accelerated maturity of
such Loan) or if any fee or other amount due hereunder shall not be paid when
due, the Company's right to select pricing options shall cease, all Loans, and
such interest, fee or amount due hereunder, to the extent permitted by
applicable law, shall bear interest (payable on demand, and in any event on the
first day of each month, and computed daily on the basis of a 360-day year for
actual days elapsed) at the Post Default Rate.

          (e)  All agreements between the Company and the Bank are hereby
expressly limited so that in no contingency or event whatsoever, whether by
reason of acceleration of maturity of the Notes or otherwise, shall the amount
paid or agreed to be paid to

                                      -12-
<PAGE>

the Bank for the use or the forbearance of the Notes 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 Notes 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 Company and the Bank in the execution, delivery and acceptance of the Notes
to contract in strict compliance with the laws of the State of New York 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 Bank 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 Company and the
Bank.

     2.10 Optional Prepayments; Indemnities:  (a) Subject to the provisions
          ---------------------------------
of (b) below, the Company may at its option at any time or from time to time
prepay a Loan in whole or in part, without premium or penalty, upon at least one
(1) Business Day prior written notice to the Bank specifying the date and the
amount of prepayment. Partial prepayments shall be in the amount of One Hundred
Thousand and 00/100 ($100,000.00) Dollars or an integral multiple thereof and
each prepayment shall be made together with interest accrued thereon to and
including the date of prepayment. The Company may not prepay any Loan (other
than a Fluctuating Rate Loan) prior to the last day of the Interest Period
therefor. Any partial prepayment of the Term Loan shall be applied to the last
maturing installments in inverse order of their respective maturities.

          (b)  The Company may prepay a LIBOR Rate Loan only upon at least three
(3) Business Days prior written notice to the Bank (which notice shall be
irrevocable), and any such prepayment shall occur only on the last day of the
Interest Period for such LIBOR Rate Loan.  The Company shall pay to the Bank,
upon request of the Bank, such amount or amounts as shall be sufficient (in the
reasonable opinion of the Bank) to compensate it for any loss, cost, or expense
incurred as a result of: (i) any payment of a LIBOR Rate Loan on a date other
than the last day of the Interest Period for such Loan; (ii) any failure by the
Company to borrow a LIBOR Rate Loan on the date specified by the Company's
written notice; (iii) any failure by the Company to pay a LIBOR Rate Loan on the
date for payment specified in the Company's written notice.  Without limiting
the foregoing, the Company shall pay to the Bank

                                      -13-
<PAGE>

a "yield maintenance fee" in an amount computed as follows: The current rate for
United States Treasury securities (bills on a discounted basis shall be
converted to a bond equivalent) with a maturity date closest to the term chosen
pursuant to the Fixed Rate Election as to which the prepayment is made, shall be
subtracted from the LIBOR in effect at the time of prepayment. If the result is
zero or a negative number, there shall be no yield maintenance fee. If the
result is a positive number, then the resulting percentage shall be multiplied
by the amount of the principal balance being prepaid. The resulting amount shall
be divided by 360 and multiplied by the number of days remaining in the term
chosen pursuant to the Fixed Rate Election as to which the prepayment is made.
Said amount shall be reduced to present value calculated by using the above
referenced United States Treasury securities rate and the number of days
remaining in the term chosen pursuant to the Fixed Rate Election as to which
prepayment is made. The resulting amount shall be the yield maintenance fee due
to the Bank upon the payment of a LIBOR Rate Loan. Each reference in this
paragraph to "Fixed Rate Election" shall mean the election by the Company of the
LIBOR Rate. If by reason of an Event of Default, the Bank elects to declare the
Note to be immediately due and payable, then any yield maintenance fee with
respect to a LIBOR Rate Loan shall become due and payable in the same manner as
though the Company had exercised such right of prepayment.

     If by reason of an Event of Default the Bank elects to declare a Note to be
immediately due and payable, then any amounts due pursuant hereto shall become
due and payable in the same manner as though the Company had exercised such
right of prepayment.

     A certificate as to any additional amounts payable pursuant to this Section
2.10 setting forth the basis and method of determining such amounts shall be
conclusive, absent manifest error, as to the determination by the Bank set forth
therein if made reasonably and in good faith.  The Company shall pay any amounts
so certified to it by the Bank within ten (10) days of receipt of any such
certificate.  For purposes of this Section 2.10, all references to the "Bank"
shall be deemed to include any participant in the Revolving Credit Commitment
and/or the Term Loan.

     2.11 Regulatory Capital Requirements:  If any existing or future law,
          -------------------------------
regulation, or guideline or the interpretation thereof by any court or
administrative or Governmental Authority charged with the administration
thereof, or compliance by the Bank with any request or directive (whether or not
having the force of law) of any such authority, imposes, modifies, deems
applicable or results in the application of any capital maintenance, capital
ratio or similar requirement against loan commitments made by the Bank (or
participations therein) or the Bank in anticipation of the effectiveness of any
capital maintenance, capital ratio or similar requirement takes reasonable
action to enable itself to comply

                                      -14-
<PAGE>

therewith, and the result thereof is to impose upon the Bank or increase any
capital requirement applicable as a result of the making or maintenance of the
Revolving Credit Commitment or participations therein (which imposition of or
increase in capital requirements may be determined by the Bank's reasonable
allocation of the aggregate of such capital impositions or increases) then,
within fifteen (15) days after demand by the Bank, the Company shall immediately
pay to the Bank from time to time as specified by the Bank additional fees which
shall be sufficient to compensate the Bank for such impositions of or increase
in capital requirements, together with interest on each such amount from fifteen
(15) days after the date demanded until payment in full thereof at the Post
Default Rate. A certificate setting forth in reasonable detail the computation
of the amounts necessary to compensate the Bank as a result of an imposition of
or increase in capital requirements submitted by the Bank to the Company shall
be conclusive, absent manifest error or bad faith, as to the amount thereof.

     2.12  Increased Costs. If the Bank determines that the effect of any
           ---------------
applicable law or government regulation, guideline or order or the
interpretation thereof by any Governmental Authority charged with the
administration thereof (such as, for example, a change in official reserve
requirements which the Bank is required to maintain in respect of loans or
deposits or other funds procured for funding such loans) is to increase the cost
to the Bank of making or continuing Loans hereunder or to reduce the amount of
any payment of principal or interest receivable by the Bank thereon, then the
Company will pay to the Bank on demand such additional amounts as the Bank may
determine to be required to compensate the Bank for such additional costs or
reduction.  Any additional payment under this Section will be computed from the
effective date at which such additional costs have to be borne by the Bank.  A
certificate as to any additional amounts payable pursuant to this Section 2.12
setting forth in reasonable detail the basis and method of determining such
amounts shall be conclusive, absent manifest error, as to the determination by
the Bank set forth therein if made reasonably and in good faith.  The Company
shall pay any amounts so certified to it by the Bank within ten (10) days of
receipt of any such certificate.  For purposes of this Section 2.12 all
references to a "Bank" shall be deemed to include any participant in the Bank's
Revolving Credit Commitment and/or the Loans.

     2.13  Change in Legality:  (a) Notwithstanding anything to the contrary
           ------------------
herein contained, if any change in any law or regulation or in the
interpretation thereof by any Governmental Authority charged with the
administration or interpretation thereof shall make it unlawful for the Bank to
make or maintain any LIBOR Rate Loan, then, by written notice to the Company,
the Bank may:

                                      -15-
<PAGE>

               (i)   declare that LIBOR Rate Loans will not thereafter be made
by the Bank hereunder, whereupon the Company shall be prohibited from requesting
LIBOR Rate Loans from the Bank hereunder unless such declaration is subsequently
withdrawn; and

               (ii)  require that all outstanding LIBOR Rate Loans made by it be
converted to Fluctuating Rate Loans, in which event (x) all such Revolving
Credit Loans made by the Bank shall be automatically converted to Fluctuating
Rate Loans as of the effective date of such notice as provided in paragraph (b)
below and (y) all payments and prepayments of principal which would otherwise
have been applied to repay the converted LIBOR Rate Loans shall instead be
applied to repay the Fluctuating Rate Loans resulting from the conversion of
such Revolving Credit Loans.

          (b)  For purposes of this Section 2.13, a notice to the Company by the
Bank pursuant to paragraph (a) above shall be sent and deemed effective in
accordance with the provisions of Section 9.13 hereof and (ii) for purposes of
this Section 2.13 all references to a "Bank" shall be deemed to include any
participant in the Bank's Revolving Credit Commitment and/or the Loans.

      2.14 Letters of Credit:  Each Letter of Credit shall be issued by the
           -----------------
Bank upon receipt and processing of the Bank's normal letter of credit
application provided that the Bank need not issue any Letter of Credit that
would extend beyond the Termination Date or has a stated amount of less than Ten
Thousand ($10,000.00) Dollars.  Letters of Credit issued hereunder shall be
utilized for the import of raw materials or inventory and shall have terms of no
more than 180 days.  The Company shall pay to the Bank, upon issuance of the
Letter of Credit, a letter of credit commission in the amount of one (1%)
percent per annum of the stated amount of the Letter of Credit calculated to the
expiration date of the Letter of Credit plus the Bank's standard processing fees
from time to time in effect.

      2.15 Termination of Letter of Credit Obligations:  Notwithstanding
           -------------------------------------------
anything to the contrary herein, if any restriction is imposed on the Bank
(including without limitation any change in or limitation upon letters of
credit) which would prevent the Bank from issuing Letters of Credit or
maintaining its obligation to issue Letters of Credit then the Bank may, by
notice to the Company in writing, terminate such obligations hereunder.

      2.16 Mandatory Payment; Drawings:  The Company is obligated, and
           ---------------------------
hereby unconditionally agrees to pay immediately to the Bank an amount equal to
any drawing on a Letter of Credit on the date of such drawing.  If the Company
shall fail to make any such payment to the Bank the payment made by the Bank
under any such Letter of Credit shall immediately constitute, without necessity
of further act or evidence, an Advance repayable on demand.

                                      -16-
<PAGE>

      2.17 Reimbursement: Master Agreement.  In the event that the Company
           -------------------------------
fails to pay any amount that is due and owing to FNB under and pursuant to the
Master Agreement (after giving effect to any applicable grace period), then upon
demand by FNB, in its sole discretion, the Bank shall pay such amount directly
to FNB for the account of the Company and the Company hereby authorizes and
consents to such payment by the Bank.  The Company agrees that (i) FNB shall
have no obligation to demand that the Bank advance such funds on behalf of the
