the date hereof until the Revolving Credit Termination Date a principal amount
which shall not exceed the lesser of (i) $10,000,000 in the aggregate at any one
time outstanding and (ii) the Marketable Securities Value.

2.1b VOLUNTARY REDUCTIONS OF REVOLVING CREDIT COMMITMENT; MANDATORY AND
VOLUNTARY PRINCIPAL PAYMENTS.

        (i) VOLUNTARY REDUCTIONS. Upon two (2) Business Days' notice to the
Lender, the Borrower may from time to time voluntarily permanently reduce the
Revolving Credit Commitment. Each voluntary reduction shall be in a minimum
amount of $500,000. The portion of the Revolving Credit Commitment so terminated

Commitment, as so reduced. All such reductions shall be without penalty or

in a minimum amount of $100,000; provided, however, that if the entire amount of
Revolving Credit Advances available to the Borrower is less than $100,000, then
such Revolving Credit Advance shall be for such entire amount.

2.1d REQUESTS FOR REVOLVING CREDIT ADVANCES. Each request for a Revolving Credit
Advance shall be made to the Lender orally or in writing pursuant to the
execution and delivery by the Borrower to the Lender of a Loan Request, by an
Authorized Officer of the Borrower, by 10:00 A.M. (Eastern time):

Credit Advance if the Revolving Credit Advance is initially to bear interest at

disbursement on the date specified in such request. The Lender shall make each
Revolving Credit Advance available to the Borrower in immediately available
funds at the principal office of the Lender on the date of such Revolving Credit
Advance by depositing the proceeds of such Loan in the Borrower's demand deposit
account maintained with the Lender, absent written instructions from the
Borrower to the contrary.

where relevant, the LIBOR Rate Interest Periods as provided for in this
Agreement. Any such communication may be oral or written and if oral it shall be
followed promptly by written confirmation of such Interest Rate Option election
executed by an Authorized Officer of the Borrower.

2.2h LAWFUL INTEREST RATES INTENDED. In no event whatsoever shall the interest
rates charged hereunder exceed the highest rate permissible under any law which
a court of competent jurisdiction shall, in a final determination, deem
applicable hereto. In the event that such a court determines that the Lender has
received interest hereunder in excess of the highest applicable rate, the Lender
shall promptly refund such excess to the Borrower, or at the Lender's option,
apply such excess in reduction of the principal balance of the Obligations owing
to the Lender.

2.3 PREPAYMENTS: ALLOCATION OF REPAYMENTS.

2.3a PREPAYMENTS OF BASE RATE PORTION. The Borrower, upon oral or written notice
to the Lender by an Authorized Officer of the Borrower given not later than
12:00 noon (Eastern

                                     - 16 -
<PAGE>

time) on the proposed date for prepayment, may prepay without penalty or premium
any or all of the Base Rate Portion. Any oral notice of election hereunder shall
be followed immediately by written confirmation of such prepayment election
executed by an Authorized Officer of the Borrower.

2.3b PREPAYMENTS OF LIBOR RATE PORTIONS. Except as otherwise provided in Section
2.4c, the Borrower, upon oral or written notice to the Lender by an Authorized
Officer of the Borrower given at least three (3) Business Days prior to the
proposed date for repayment, may prepay all or any part of such LIBOR Rate
Portion. If such LIBOR Rate Portion is prepaid on the last day of the LIBOR Rate
Interest Period applicable thereto, such prepayment shall be without premium or
penalty. If the Borrower prepays a LIBOR Rate Portion other than on the last day
of the LIBOR Rate Interest Period applicable thereto, the Borrower agrees to
pay, in addition to the other amounts set forth in this Section 2.3b, such
additional amounts as may be necessary to compensate the Lender for any loss and
any direct or indirect costs, including the costs of reemployment of funds
prepaid at rates lower than the cost to the Lender of such funds. Such losses
and costs shall be specified in writing to the Borrower by the Lender (and such
specifications shall set forth in reasonable detail the calculation of such
losses and costs) and such specifications shall, absent manifest error, be
binding and conclusive on the Borrower. Such prepayment shall include the then
outstanding principal amount of the LIBOR Rate Portion being prepaid together
with accrued interest, fees and other amounts then due and payable on the amount
prepaid, to the day of such prepayment. Except as provided in this Section 2.3b,
there shall be no voluntary prepayment of any LIBOR Rate Portion.

2.3c ALLOCATION OF REPAYMENTS OF PRINCIPAL. Any voluntary prepayment pursuant to
this Section 2.3 shall be applied first to the repayment of any LIBOR Rate
Portion of the Loans for which its associated LIBOR Rate Interest Period expires
on the date of such payment; second, to the reduction of the Base Rate Portion
of the Loans; and third, to the reduction of such LIBOR Rate Portions of the
Loans as directed by the Borrower, and if the Borrower fails to give such
directions, or if a Default or Event of Default has occurred and is continuing,
to the reduction of such LIBOR Rate Portions of the Loans as the Lender may
select in its sole and absolute discretion. Any reduction in any LIBOR Rate
Portion on a date other than the date on which its associated LIBOR Rate
Interest Period expires may result in a funding loss for which the Borrower will
owe the Lender an indemnity payment pursuant to Section 2.4 hereof.

2.4. YIELD PROTECTION.

2.4a ILLEGALITY. If any change subsequent to the Closing Date in any Law or in
the interpretation or application thereof by any Governmental Authority or in
the compliance with any guideline or request from any Governmental Authority,
shall make it unlawful for the Lender to maintain or give effect to its
obligations as contemplated under the Revolving Credit Commitment, the Lender
shall notify the Borrower in writing of its determination of such unlawfulness
and an explanation thereof. Thereafter, the Lender's obligation to make
available any further Loans hereunder shall forthwith be cancelled and the
Borrower, within thirty (30) days, or within such longer period as may be
allowed by Law, if any, shall repay to the Lender the outstanding principal
amount of all Loans, together with interest thereon to the date of repayment and
all other outstanding Fees and other Obligations, if any, due as of the date of
termination; provided, however, that the Lender's obligations which are lawful,
if severable from those which are unlawful, shall continue, and with respect to
those obligations, this Agreement shall not terminate.

                                     - 17 -
<PAGE>

2.4b CHANGE IN LAW. If any Law issued after the Closing Date (including, without
limitation, Regulation D, or if any change on or after the Closing Date in any
Law (including, without limitation, Regulation D) or in the interpretation
thereof by any Governmental Authority charged with the administration thereof,
shall

        (i) subject the Lender to any tax, levy, impost, charge, fee, duty,
deduction or withholding of any kind under this Agreement (other than any tax
imposed or based upon the income of the Lender and payable to any Governmental
Authority in the United States of America, any state or any municipality
thereof); or

        (ii) change the basis of taxation of the Lender with respect to payments
of principal or interest or other amounts due under this Agreement (other than
any change which affects, and only to the extent that it affects, the taxation
by the United States, any state or any municipality thereof based upon the
income of the Lender); or

        (iii) impose, modify or deem applicable any reserve, special deposit or
similar requirements against assets held by the Lender with respect to this
Agreement (other than such requirements which result solely from a change in the
credit quality of the Borrower or which are included in the determination of the
applicable rate of interest hereunder); or

        (iv) impose upon the Lender any other obligation or condition with
respect to this Agreement, and the result of any of the foregoing is to increase
the cost to the Lender, to decrease the yield to the Lender with respect to the
Loans, to reduce the income receivable by the Lender or to impose any expenses
upon the Lender with respect to the Loans by an amount which the Lender
reasonably deems material, then and in any such case:

                (A) the Lender shall promptly notify the Borrower of the
happening of such event;

                (B) the Borrower shall pay to the Lender, within five (5)
Business Days of written demand, such amount as will compensate the Lender for
such additional cost or reduced amount, calculated from the date of the
notification by the Lender; and

                (C) the Borrower may pay to the Lender the affected Loan in full
without the payment of any additional amount other than on account of the
Lender's out-of-pocket losses (including funding losses, if any, as provided in
Section 2.4c below) not otherwise provided for in subparagraph (B) immediately
above.

The Lender shall present to the Borrower a certificate setting forth such
increased cost or reduced amount. Such certificate shall set forth in reasonable
detail the calculation of the amount due and the Lender's reasons for invoking
the provisions of this Section 2.4b. Such certificate shall be evidence of the
amount due thereunder except in the case of manifest error in computation.

2.4c INDEMNIFICATION. The Borrower agrees to indemnify the Lender, on demand,
against any loss or expense (including loss of profit) which the Lender may
sustain or incur in liquidating or employing deposits from third parties
acquired to effect, fund or maintain such LIBOR Rate Portions or any part
thereof as a consequence of (i) the failure of the Borrower to

                                     - 18 -
<PAGE>

make a payment on the due date thereof, (ii) the failure of the Borrower to
borrow under, convert to or renew under the LIBOR Rate Option on the proposed
effective date of such borrowing, conversion or renewal, or (iii) the payment,
prepayment or conversion by the Borrower of any LIBOR Rate Portions for any
reason on a day other than the last day of the applicable LIBOR Rate Interest
Period. The Lender's determination of an amount payable under this Subsection
2.4c shall be evidence of such amount absent manifest error.

2.5 SPECIAL PROVISIONS RELATING TO THE LIBOR RATE OPTION.

2.5a LIBOR RATE UNASCERTAINABLE. In the event that on any date on which a LIBOR
Rate Option would otherwise be set, the Lender shall have determined (which
determination shall be final and conclusive) that, by reason of circumstances
affecting the London interbank market, adequate, reasonable means do not exist
for ascertaining the LIBOR Rate, the Lender shall give prompt notice of such
determination to the Borrower. Until the Lender notifies the Borrower that the
circumstances giving rise to such determination no longer exist (which notice
shall be given promptly following receipt of knowledge thereof by the Lender),
the right of the Borrower to borrow under, convert to or renew the LIBOR Rate
Option shall be suspended. Any notice of borrowing under, conversion to or
renewal of the LIBOR Rate Option which was to become effective during the period
of such suspension shall be treated as a request to borrow under, convert to or
renew the Base Rate Option with respect to the principal amount therein
specified.

2.5b INABILITY TO OFFER LIBOR RATE. In the event that the Lender shall
determine, in its sole discretion, that it is unable to obtain deposits in the
London interbank market in sufficient amounts and with maturities related to
such LIBOR Rate Portions which would enable the Lender to fund such LIBOR Rate
Portions, then the Lender shall notify the Borrower that the right of the
Borrower to borrow under, convert to or renew the LIBOR Rate Option, shall be
suspended. Such notice shall set forth in reasonable detail the Lender's reasons
for invoking the provisions of this Section 2.5b. Following notification of the
suspension of the LIBOR Rate Option with respect to the Lender, the Borrower
agrees to negotiate with the Lender for a modified or alternative fixed rate of
interest, which will allow the Lender to realize its anticipated and
bargained-for yield. In the event that the Borrower and the Lender cannot agree
on a modified or alternative fixed rate of interest, any notice of borrowing
under, conversion to or renewal of the LIBOR Rate Option which was to become
effective during the period of suspension shall be treated as a request to
borrow under, convert to or renew the Base Rate Option with respect to the
principal amount specified therein attributable to the Lender.

2.5c ILLEGALITY. If the Lender shall determine in good faith (which
determination shall be final and conclusive) that compliance with any Law
(whether or not having the force of law) or the interpretation or application
thereof by any Governmental Authority, has made it unlawful for the Lender to
make or maintain the Loans under the LIBOR Rate Option, the Lender shall give
notice of such determination to the Borrower, which notice shall set forth in
reasonable detail the Lender's reasons for invoking the provisions of this
Section 2.5c. Notwithstanding any provision of this Agreement to the contrary,
unless and until the Lender shall have given notice to the Borrower that the
circumstances giving rise to such determination no longer apply (which notice
shall be given promptly following receipt of knowledge thereof by the Lender):

                                     - 19 -
<PAGE>

        (i) with respect to any LIBOR Rate Interest Periods thereafter
commencing, interest with respect to an amount equal to the corresponding LIBOR
Rate Portion shall be computed and payable under the Base Rate Option; and

        (ii) on such date, if any, as shall be required by law, an amount equal
to any LIBOR Rate Portion, as the case may be, then outstanding shall be
automatically converted to the Base Rate Option and the Borrower shall pay to
the Lender the accrued and unpaid interest on such amounts to (but not
including) such conversion date.

The Borrower shall pay the Lender any additional amounts reasonably necessary to
compensate the Lender for any costs incurred by the Lender as a result of any
conversion pursuant to clause (ii) above which occurs on a day other than the
last day of the relevant LIBOR Rate Interest Period, including, but not limited
to, any interest or fees payable by the Lender to lenders of funds obtained by
it to loan or maintain the lending of the Loans so converted. The Lender shall
furnish to the Borrower a certificate as to the amount necessary to compensate
it for such costs, which certificate shall set forth in reasonable detail the
calculation of the amount due. Such certificate shall constitute conclusive
evidence of the amount due thereunder absent any manifest error in computation.
The Borrower shall pay such amount to the Lender, as additional consideration
hereunder, within ten (10) days of the Borrower's receipt of such certificate.

2.5d CALCULATION OF INTEREST AND REVOLVING CREDIT COMMITMENT FEE. Interest and
the Revolving Credit Commitment Fee shall be calculated on the basis of the
actual number of days elapsed, using a year of 360 days.

2.6 CAPITAL ADEQUACY. If (i) any adoption of or any change in or in the
interpretation of any Law, (ii) compliance with any Law of any Governmental
Authority exercising control over banks or financial institutions generally or
any court (whether or not having the force of law), or (iii) any change in the
force or effectiveness of the regulations set forth at 12 C.F.R. Part 3
(Appendix A), 12 C.F.R. Part 208 (Appendix A), 12 C.F.R. Part 225 (Appendix A)
or 12 C.F.R. Part 325 (Appendix A) affects or would affect the amount of capital
required or expected to be maintained by the Lender (a "CAPITAL ADEQUACY
EVENT"), and the result of such Capital Adequacy Event is to reduce the rate of
return on the Lender's capital as a consequence thereof to a level below that
which the Lender could have achieved but for such Capital Adequacy Event, taking
into consideration the Lender's policies with respect to capital adequacy, by an
amount which the Lender deems to be material, the Lender shall deliver to the
Borrower a statement of the amount necessary to compensate the Lender for the
reduction in the rate of return on its capital attributable to the Loans and the
commitment hereunder (the "CAPITAL COMPENSATION AMOUNT"). The Lender shall
determine the Capital Compensation Amount in good faith, using reasonable
attribution and averaging methods. Such amount shall be due and payable by the
Borrower to the Lender ten (10) Business Days after such notice is given by the
Lender.

2.7 UTILIZATION OF COMMITMENTS IN OPTIONAL CURRENCIES.

2.7a PERIODIC COMPUTATIONS OF DOLLAR EQUIVALENT AMOUNTS OF LOANS OUTSTANDING.
The Lender will determine the Dollar Equivalent amount of (i) proposed Loans to
be denominated in an Optional Currency as of the date of the requested
disbursement, (ii) outstanding Loans denominated in an Optional Currency as of
the last Business Day of each

                                     - 20 -
<PAGE>

month, and (iii) outstanding Loans denominated in an Optional Currency as of the
end of each Interest Period (each such date under clauses (i) through (iii) a
"COMPUTATION DATE").

2.7b NOTICE FROM LENDER THAT OPTIONAL CURRENCIES ARE UNAVAILABLE TO FUND NEW
LOANS. The Lender shall be under no obligation to make the Loans requested by
the Borrower which are denominated in an Optional Currency if the Lender
notifies the Borrower by 12:00 noon (Eastern time) one (1) Business Day prior to
the borrowing or issuance date for such Loan that the Lender cannot provide such
Loan in such Optional Currency. If the Borrower receives a notice described in
the preceding sentence, the Borrower may, by notice to the Lender not later than
5:00 P.M. (Eastern time) one (1) Business Day prior to the borrowing or issuance
date for such Loan, withdraw the Loan Request for such Loan. If the Borrower
withdraws such Loan Request, the Lender shall not make such Loan. If the
Borrower does not withdraw such Loan Request before such time, (i) the Borrower
shall be deemed to have requested that the Loans referred to in its Loan Request
shall be made in Dollars in an amount equal to the Dollar Equivalent amount of
such Loans.

2.7c NOTICES FROM LENDER THAT OPTIONAL CURRENCIES ARE UNAVAILABLE TO FUND
RENEWALS OF LIBOR RATE OPTION LOANS. If the Borrower delivers a Loan Request
requesting that the Lender renew the LIBOR Rate Option with respect to an
outstanding Portion of Loans denominated in an Optional Currency, the Lender
shall be under no obligation to renew such LIBOR Rate Option if the Lender
delivers to the Borrower notice by 12:00 noon (Eastern time) one (1) Business
Day prior to effective date of such renewal that the Lender cannot continue to
provide Loans in such Optional Currency. If the Lender shall have so notified
the Borrower that any such continuation of Loans denominated in an Optional
Currency issued in an Optional Currency is not then available, any notice of
renewal with respect thereto shall be deemed withdrawn, and such Loans
denominated in an Optional Currency shall be re-denominated into Base Rate Loans
in Dollars with effect from the last day of the Interest Period with respect to
any such Loans denominated in an Optional Currency. The Lender will promptly
notify the Borrower of any such re-denomination, and in such notice, the Lender
will state the aggregate Dollar Equivalent amount of the re-denominated Loans
denominated in an Optional Currency issued in an Optional Currency as of the
Computation Date with respect thereto.

2.7d REQUESTS FOR ADDITIONAL OPTIONAL CURRENCIES. The Borrower may deliver to
the Lender a written request that Loans hereunder also be permitted to be made
in any other lawful currency (other than Dollars), in addition to the currencies
specifically identified in the definition of "Optional Currency"; provided that
such currency must be freely traded in the offshore interbank foreign exchange
markets, freely transferable, freely convertible into Dollars, available to the
Lender in the applicable interbank market, meet the definition of "Optional
Currency", as defined herein, and otherwise be acceptable to the Lender in its
discretion. The Lender may grant or accept such request in its sole discretion.
The Lender will promptly notify the Borrower of its acceptance or rejection of
the Borrower's request.

2.7e OPTIONAL CURRENCY FEE. The Borrower shall pay to the Lender in Dollars the
Lender's fees which are then in effect with respect to Loans denominated in an
Optional Currency as the Lender may generally charge or incur in connection with
the funding, maintenance, modification (if any), negotiation, and administration
of Loans denominated in an Optional Currency.

                                     - 21 -
<PAGE>

2.7f CURRENCY REPAYMENTS. Notwithstanding anything contained herein to the
contrary, the entire amount of principal of and interest on any Loan made in an
Optional Currency shall be repaid in the same Optional Currency in which such
Loan was made, provided, however, that if it is impossible or illegal for the
Borrower to effect payment of a Loan in the Optional Currency in which such Loan
was made, or if the Borrower defaults in its obligation to do so, the Lender may
at its option permit such payment to be made (i) at and to a different location,
subsidiary, affiliate or correspondent of the Lender, or (ii) in the Equivalent
Amount of Dollars or (iii) in an Equivalent Amount of such other currency
(freely convertible into Dollars) as the Lender may solely at its option
designate. Upon any events described in items (i) through (iii) of the preceding
sentence, the Borrower shall make such payment and the Borrower agrees to hold
the Lender harmless from and against any loss incurred by the Lender arising
from the cost to the Lender of any premium, any costs of exchange, the cost of
hedging and covering the Optional Currency in which such Loan was originally
made, and from any change in the value of Dollars, or such other currency, in
relation to the Optional Currency that was due and owing. Such loss shall be
calculated for the period commencing with the first day of the Interest Period
for such Loan and continuing through the date of payment thereof. Without
prejudice to the survival of any other agreement of the Borrower hereunder, the
Borrower's obligations under this Section 2.7f shall survive termination of this
Agreement.

2.7g OPTIONAL CURRENCY AMOUNTS. Notwithstanding anything contained herein to the
contrary, the Lender may, with respect to notices by the Borrower for Loans in
an Optional Currency or voluntary prepayments of less than the full amount of an
Optional Currency Revolving Credit Advance, engage in reasonable rounding of the
Optional Currency amounts requested to be loaned or repaid; and, in such event,
the Lender shall promptly notify the Borrower of such rounded amounts and the
Borrower's request or notice shall thereby be deemed to reflect such rounded
amounts.

2.7h CURRENCY FLUCTUATIONS. If on any Computation Date the sum of the Dollar
Equivalent of all Loans is greater than the Revolving Credit Commitment, as a
result of a change in exchange rates between one or more Optional Currencies and
Dollars, then the Lender shall notify the Borrower of the same. Within two (2)
Business Days after receiving such notice, the Borrower shall pay or prepay
(subject to the Borrower's indemnity obligations under this Agreement) Loans
denominated in an Optional Currency issued in an Optional Currency in amounts
such that the sum of the Dollar Equivalent of all Loans does not exceed the
Revolving Credit Commitment, all after giving effect to such payments or
prepayments.

2.7i INTERBANK MARKET PRESUMPTION. For all purposes of this Agreement and the
Revolving Credit Note with respect to any aspects of the LIBOR Rate, any Loan
under the LIBOR Rate Option or any Optional Currency, the Lender and the Lender
shall be presumed to have obtained rates, funding, currencies, deposits, and the
like in the applicable interbank market regardless whether it did so or not; and
the Lender's determination of amounts payable under, and actions required or
authorized by this Agreement shall be calculated, at the Lender's option, as
though the Lender funded each Portion of Loans under the LIBOR Rate Option
through the purchase of deposits of the types and maturities corresponding to
the deposits used as a reference in accordance with the terms hereof in
determining the LIBOR Rate applicable to such Loans, whether in fact that is the
case.

                                     - 22 -
<PAGE>

2.7j JUDGMENT CURRENCY.

        (i) CURRENCY CONVERSION PROCEDURES FOR JUDGMENTS. If for the purposes of
obtaining judgment in any court it is necessary to convert a sum due hereunder
or under a Revolving Credit Note in any currency (the "ORIGINAL CURRENCY") into
another currency (the "OTHER CURRENCY"), the parties hereby agree, to the
fullest extent permitted by Law, that the rate of exchange used shall be that at
which in accordance with normal banking procedures the Lender could purchase the
Original Currency with the Other Currency after any premium and costs of
exchange on the Business Day preceding that on which final judgment is given.

        (ii) INDEMNITY IN CERTAIN EVENTS. The obligation of the Borrower in
respect of any sum due from the Borrower to the Lender hereunder shall,
notwithstanding any judgment in an Other Currency, whether pursuant to a
judgment or otherwise, be discharged only to the extent that, on the Business
Day following receipt by the Lender of any sum adjudged to be so due in such
Other Currency, the Lender may in accordance with normal banking procedures
purchase the Original Currency with such Other Currency. If the amount of the
Original Currency so purchased is less than the sum originally due to the Lender
in the Original Currency, the Borrower agrees, as a separate obligation and
notwithstanding any such judgment or payment, to indemnify the Lender against
such loss.

2.8 FEES.

2.8a REVOLVING CREDIT COMMITMENT FEE. The Borrower agrees to pay to the Lender
on March 31, 1999 and quarterly thereafter to and including the Revolving Credit
Termination Date, a Revolving Credit Commitment Fee calculated at the rate of
1/4 of 1% per annum on the average daily (computed at the opening of business)
unused amount of the Revolving Credit Commitment for the quarter then ending;
provided, that the first payment shall be calculated for the period beginning on
the Closing Date and ending on March 31, 1999. All payments of the Revolving
Credit Commitment Fee shall be deemed fully earned when paid and shall be
nonrefundable.

2.8b FACILITY FEE. The Borrower shall pay to the Lender prior to or
simultaneously with the first advance hereunder the Facility Fee in the amount
of $20,000, which shall be fully earned when paid and non-refundable.

2.8c LATE FEES. The Lender shall have the right to assess a late fee if any
principal, interest, fees or other amounts due under the Loan Documents are not
paid within ten (10) days of their due date. Such late fee shall be in an amount
equal to the greater of $20.00 or one percent (1%) of the amount not timely
paid.

2.9 LOAN ACCOUNT. The Lender shall open and maintain on its books records
relating to the Loans made, repayments, prepayments, the computation and payment
of interest and the Fees and the computation of other amounts due and sums paid
to the Lender pursuant hereto. Except in the case of manifest error in
computation, such records shall be presumed to be conclusive and binding on the
Borrower as to the amount at any time due to the Lender from the Borrower
pursuant hereto.

2.10 TIME, PLACE AND MANNER OF PAYMENTS. All payments to be made by the Borrower
under any of the Loan Documents shall be made at the principal office of the
Lender at 20 Stanwix Street, Pittsburgh Pennsylvania and shall be paid in
Dollars in immediately available funds no later than 12:00 noon (Eastern time)
on the date such payment is due. If the

                                     - 23 -
<PAGE>

date on which any payment is due is not a Business Day such payment shall be due
and payable on the next succeeding day which is a Business Day and interest
shall accrue on any principal amount of such a payment until the date on which
such principal amount is paid.

2.11 PAYMENT FROM ACCOUNTS MAINTAINED BY THE BORROWER. In the event that any
payment of principal, interest, Fees or any other amount due the Lender under
any of the Loan Documents is not paid when due, the Lender is hereby authorized
to effect such payment by debiting any demand deposit account of the Borrower
maintained with the Lender. This right of debiting accounts of the Borrower is
in addition to any right of set-off accorded the Lender hereunder or by
operation of law.

2.12 ALL OBLIGATIONS TO CONSTITUTE ONE OBLIGATION. All Obligations shall
constitute one general obligation of the Borrower, and shall be secured by the
Lender's security interest in and lien upon all of the Collateral of the
Borrower and by all other security interests and liens heretofore, now or at any
time or times hereafter granted by the Borrower to the Lender.

ARTICLE III. REPRESENTATIONS AND WARRANTIES

        To induce the Lender to enter into this Agreement and to make the Loans
herein provided for, the Borrower hereby makes the following representations and
warranties to the Lender, all of which shall be continuing in nature and shall

existing and in good standing under the laws of the State of Delaware and is
duly qualified or licensed and in good standing as a foreign corporation
authorized to do business in each jurisdiction where the nature of its

3.4 VALIDITY; BINDING EFFECT AND ENFORCEABILITY. The Loan Documents to which the
Borrower is a party constitute legal, valid and binding obligations of the
Borrower, enforceable in accordance with their terms, except as such

Borrower, and the consummation of the transactions herein or therein
contemplated or compliance with the terms and provisions hereof or thereof by
it, do not and will not conflict with, constitute a default under or result in
any breach of (i) the terms and conditions of the Borrower's articles or
certificate of incorporation, by-laws, (ii) any Law or (iii) any material

additional Federal, state, local or other taxes for any such fiscal period or

the Borrower under the Loan Documents shall become immediately due and payable,
without the necessity of demand, presentation, protest, notice of dishonor or
notice of default, all of which are hereby expressly waived by the Borrower.
Thereafter, the Lender shall have no further obligation to make any additional
Loans hereunder. In addition, during any sixty (60)-day period described in

extensions, supplements and replacements to any of the Loan Documents, and the

of any of the Loan Documents or consent to actions taken or desired to be taken
by the Borrower. All such amendments, extensions, supplements, replacements,
waivers and consents must be in writing and signed by the Lender and the
Borrower in order to be effective. Each waiver and consent shall be effective
only for the specific instance and for the specific purpose for which it is
given. In the case of any waiver, the Borrower and the Lender shall be restored
to their former positions and rights, and any Event of Default waived shall be
deemed to be cured and not continuing, but no such waiver shall extend to any
subsequent or other Event of Default, or impair any right consequent thereon.
Neither the acceptance by the Lender of any payment required under the Loan
Documents after its due date, nor the acceptance by the Lender of interest at
the Default Rate or any other increased rate, shall constitute any waiver of the
Lender's rights under the Loan Documents.

8.3 TAXES. The Borrower agrees to pay any and all stamp, document, transfer or
recording taxes, filing fees and similar impositions payable or hereafter
determined to be payable in connection with the Loan Documents and any other

connection with the preparation, negotiation, execution and delivery of the Loan

(which shall not exceed $7,500), and (B) reasonable costs and expenses of the

its commercial banking business and in accordance with applicable law, at any
time assign to any Person or sell to one or more participants (which Person or
participants may be Affiliates of the Lender) portions of or participations in
any interest of the Lender hereunder or under the other Loan Documents. In the
event of any sale of a participation, the Lender's obligations under this
Agreement to the Borrower shall remain unchanged, the Lender shall remain solely
responsible for its performance under this Agreement, the Lender shall remain
the holder of the Revolving Credit Note for all purposes under this Agreement,
and the Borrower shall continue to deal solely and directly with the Lender in
connection with the Lender's rights and obligations under the Loan Documents.
The Borrower agrees that if amounts outstanding under the Loan Documents are due
and unpaid, or shall have been declared or shall have become due and payable
upon the occurrence of an Event of Default, each participant shall be deemed to
have, to the extent permitted by applicable law, the right of setoff in respect
of its participation in amounts owing under the Loan Documents to the same

representations, warranties and agreements of the Borrower contained herein, in
any of the other Loan Documents, or made in writing in connection herewith shall

apply such excess to the reduction of the unpaid principal amount due hereunder,
or if no principal is then due, such excess shall be refunded to the Borrower.
