same day by facsimile copy.

          (4)  The interest due on the Loan shall be payable as provided in

     3.   Interest and Principal Payments; Maturity Date.

          (1)  Prime Rate Loans.  Borrower shall pay interest in arrears on
the unpaid principal amount of the Prime Rate Tranche, from the date on
which the Prime Rate Tranche is created until such principal amount has
been repaid in full, or converted to a LIBOR Tranche, as the case may be,
(1) every thirty (30) days after the Effective Date of such Prime Rate
Tranche and (2) on the Maturity Date, at the Adjusted Prime Rate.

          (2)  Conversions to LIBOR Tranches.  By notifying Bank at least
two (2) London Business Days prior to an Effective Date, Borrower may
convert into a LIBOR Tranche all or any all or any part of any Prime Rate
Tranche at any time in a minimum principal amount of $200,000.00.  At the
end of the applicable LIBOR Interest Period, the LIBOR Tranche will convert
to a Prime Rate Tranche unless Borrower notifies Bank at least (2) London
Business Bays before the end of the existing LIBOR Interest Period that

Borrower is electing to continue all or any part of the Tranche as a LIBOR
Tranche and is selecting a new LIBOR Interest Period.

          (3)  LIBOR Tranches.  Borrower shall pay interest in arrears on
the unpaid principal amount of each LIBOR Tranche at the Adjusted LIBOR
Rate for such LIBOR Tranche from the date on which such LIBOR Tranche is
created until such principal amount has been paid in full, or converted to
a Prime Rate Tranche, as the case may be, (1) every 30 days after the
Effective Date of such LIBOR Tranche, and (2) on the Maturity Date at the
Adjusted LIBOR Rate.

          (4)  Principal Repayment.  Borrower shall repay the outstanding
principal balance of the Loan, all accrued and unpaid interest thereon and
any other sums then outstanding hereunder or under the Loan Documents on
October 31, 2001 (the "Maturity Date").

          (5)  Operating Account.  Borrower covenants and agrees to
maintain an operating account with Bank at all times during which any
portion of the Loan remains outstanding (the "Operating Account").
Borrower hereby authorizes Bank to charge the Operating Account for all
payments hereunder as they become due.  Borrower agrees to keep in the
Operating Account sufficient amount to make such payments as and when they
come due.  Bank's failure to so charge the Operating Account in order to
satisfy Borrower's payment obligations hereunder shall not relieve
Borrower's obligations to make all such payments.  In the event that
Borrower shall fail to maintain a sufficient balance in the Operating
Account to satisfy a payment obligation on the date such payment becomes
due, Borrower shall continue to be obligated to make such payment and, if
such payment is not made by Borrower in some other manner on or before the
date such payment becomes due, such failure shall constitute an Event of
Default hereunder.  All payments received by Bank from Borrower shall be
applied in the following order: (i) to the payment of fees and other costs
and expenses then due and owing from Borrower, (ii) to the payment of
accrued and unpaid interest then due, (iii) to the payment of any
outstanding principal hereunder.

          (6)  Interest Calculation.  Both before and after any default,
interest shall be calculated on the basis of a 360 day year but charged on
the basis of the actual number of days elapsed in any calender year or part
thereof.

     4.   Prepayments.

          (1)  Borrower may repay the Prime Rate Tranches in whole or in
part at any time and from time to time in a minimum amount of Two Hundred
Thousand Dollars ($200,000.00).

          (2)  Borrower may, at any time, prepay the principal balance of a
LIBOR Rate Tranche in whole or in part; provided, however, that Borrower
shall indemnify Bank against Bank's loss or expense in employing deposits
as a consequence of any prepayment of any LIBOR Rate Tranche on a date
other than the last day of the LIBOR Interest Period ("Indemnified Loss or
Expense").  The amount of such Indemnified Loss or Expense shall be
determined by Bank based upon the assumption that Bank funded 100% of

such LIBOR Rate Tranche in the London interbank market.  Any prepayment
shall include accrued and unpaid interest to the date of prepayment on the
principal amount prepaid and all other sums due and payable hereunder.
Nothing herein shall be deemed to alter or affect any obligations that
Borrower may have to Bank under any interest rate swap agreements.
Borrower agrees to pay the Indemnified Loss or Expense upon any prepayment
of the LIBOR Tranche, whether voluntary, required  by Bank in connection
with any acceleration of the indebtedness hereunder upon the occurrence of
an Event of Default, or as otherwise required under this Fourth Replacement
Revolver Note.  A determination of Bank as to the  amounts payable pursuant
to this Section 4(B) shall be conclusive absent manifest error.

     5.  Late Charges.  If any installment of principal or interest or both
hereunder or other payment required to made by Borrower under the other
Loan Documents is not paid within ten (10) days after becoming due,
Borrower shall pay to Bank on demand a late charge of five percent (5%) of
such overdue amount to reimburse Bank for the additional expenses to be
incurred as a result of such delinquency, but such late payment fee shall
not obligate Bank to accept any overdue payment hereunder nor limit the
rights and remedies available to Bank as a result of Borrower's default, as
hereinafter provided.  The amount of any such late charge not paid promptly
following demand shall be deemed outstanding and payable pursuant to this
Fourth Replacement Revolver Note.

     6.  Event of Default.  An Event of Default shall mean and Event of
Default as defined in the Loan Agreement.

     7.  Default Rate.  Upon the occurrence of an Event of Default
hereunder, the interest rate otherwise payable hereunder (the "Contract
Rate") shall increase immediately and without notice and thereafter shall
be payable at a rate of three (3%) per annum in excess of the Contract Rate
(said higher rate is hereinafter called the "Default Rate"), until the
Event of Default has been cured, or in the event the principal of this
Fourth Replacement Revolver Note has been accelerated, until this Fourth
Replacement Revolver Note is paid in full, including the period following
entry of any judgment on or relating to this Fourth Replacement Revolver
Note or the other Loan Documents.  Interest on any such judgment shall
accrue and be payable at the Default Rate, and not at the statutory rate of
interest, after judgment, any execution thereon, and until actual receipt
by the holder of payment in full of this Fourth Replacement Revolver Note
and said judgment.  Interest at the Default Rate shall be collectible as
part of any judgment hereunder and shall be secured by the other Loan
Documents.

     8.  Remedies.  Upon the occurrence of an Event of Default, the Bank
shall be entitled to exercise all remedies available to it under the terms
of the Loan Agreement.

     9.  Accounts.  Borrower hereby covenants and agrees that while the
Loan is outstanding it will maintain all of its primary operating accounts
with the Bank.

    10.  Waivers by Borrower, Cumulative Remedies.

          (1)  Borrower hereby waives presentment for payment, demand ,
notice of non-payment, notice of protest and protest of this Fourth
Replacement Revolver Note.  The Borrower hereby consents to any and all
extensions of time,

renewals, waivers or modifications that may be granted by the Bank with
respect to the payment or other provisions of this Fourth Replacement
Revolver Note, and agrees that additional obligors may become parties
hereto without notice to the Borrower without affecting the Borrower's
liability hereunder.

          (2)  Borrower hereby waives-the benefit of any laws which now or
hereinafter might otherwise authorize the stay of any execution to be
issued on any judgment covered on this Fourth Replacement Revolver Note.
BORROWER HEREBY WAIVES ITS RIGHT TO TRIAL BY JURY IN CONNECTION WITH THIS
FOURTH REPLACEMENT NOTE, THE LOAN AGREEMENT OR ANY OTHER LOAN DOCUMENT AND
ANY LEGAL PROCEEDING ARISING HEREUNDER OR THEREUNDER.

          (3)  No failure or delay on the part of the Bank in exercising
any right, power or privilege under this Fourth Replacement Revolver Note
and no course of dealing between the Borrower and the Bank shall operate as
a waiver thereof.  No single or partial exercise of any right, power or
privilege hereunder shall preclude any other or further exercise of any
right, power or privilege that the Bank would otherwise have.  No notice
to, or demand on, the Borrower in any case shall entitle the Borrower to
any other or further notice or demand in similar or other circumstances
would constitute a waiver of the right of the Bank to any other or further
action and any circumstances without notice or demand.

    11.  Costs and Expenses.  The Borrower agrees, in accordance with the
terms of the Loan Agreement, to pay all costs and expenses of the Bank
incurred in order to enforce any remedy available to the Bank under this
Fourth Replacement Revolver Note, the Loan Agreement or any Loan Document.

    12.  Reimbursement to Bank for Increased Costs Due to Capital Adequacy
Requirements.  If after the date hereof any change in law or regulation or
the interpretation thereof by any court of administrative or governmental
authority charged with the administration thereof, or compliance by Bank
with any request or directive (whether or not having the force of law) of
any such authority, applicable from time to time now or after the date
hereof to Banks in general, shall (A) impose, modify, deem applicable or
result in the application of any capital maintenance, capital ratio or
similar requirements against loan commitments or other facilities made by
Bank and the result thereof shall be to impose upon Bank a fee or a
requirement to increase any capital requirements applicable as a result of
the making or maintenance of the Loan (which imposition of or increase in
capital requirements may be determined by Bank's reasonable allocation of
the aggregate of such capital impositions or increases), or (B) subject
Bank to any tax, duty or other charge with respect to the Loan, the Fourth
Replacement Revolver Note, or change the basis of taxation of payments to
Bank of the principal of or interest on the Loan or any other amounts due
under this Fourth Replacement Revolver Note, in respect to of the Loan
(except for changes in the rate of tax on the overall net income of Bank
imposed by any jurisdiction in which Bank is obligated to pay taxes), then,
upon demand by Bank, Borrower shall immediately pay to Bank from time to
time as specified by Bank, such additional amounts or fees which shall be
sufficient to compensate Bank for such impositions of or increases in
capital requirements or taxes from the date of such change, together with
interest on each such amount from the date demanded

until payment in full thereof at the Default Rate with respect to amounts
or fees not paid when due.  Upon the occurrence of any event referred to
above, a certificate setting forth in reasonable detail the amounts
necessary to compensate Bank as a result of an imposition of or increase in
capital requirements or taxes submitted by Bank to Borrower shall be
conclusive, absent manifest error or bad faith, as to the amount thereof.

    13.  Special Provisions of LIBOR Tranches.

          (1)  Unavailability of Funds and Indeterminate Interest Rates.
If on or before the date Bank is to make any LIBOR Tranche or on or before
any Effective Date (1) Bank determines in good faith that it is unable to
obtain funds at the LIBOR Rate for the elected Interest Period for any
reason, including, but not limited to the unavailability of funds at such
rate, any change in existing law, any new law, the length of such Interest
Period, or otherwise or (2) Bank determines in good faith that no adequate
means exists to determine the LIBOR Rate for such Interest Period, then, at
Bank's option, Borrower shall be deemed to have requested a Prime Rate
Tranche or shall be required to elect an Interest Period of a length for
which Bank may obtain funds at the LIBOR Rate.

          (2)  Changes Affecting Ability to Maintain Funds.  If, during any
Interest Period, any change in existing law, any new law, or any other
factor beyond the control of Bank prevents Bank in its good faith
determination from maintaining funds at the rate of adjustment of which
determines the LIBOR Rate for such Interest Period and requires Bank to
cease so maintaining funds actually so maintained prior to termination of
such Interest Period, then on the date of such required cessation, Borrower
shall be required to specify a different Interest Rate for such Interest
Period or, in the alternative, to elect an Interest Period of a length for
which Bank may maintain funds at the rate the adjustment of which
determines the LIBOR Rate.  In addition, within five (5) days after Bank
notifies Borrower of such required conversion, Borrower shall reimburse
Bank for any loss or expense Bank has certified in writing to Borrower that
Bank has incurred as a result of any such required cessation.

    14.  Interest Limitation; Severability

          (1)  Nothing herein contained nor any transaction related hereto
shall be construed or shall operate either presently or prospectively to
require Borrower to pay interest at a rate greater than is now lawful in
such case to contract for, but shall require payment of interest only to
the extent of such lawful rate.  Any interest paid in excess of the lawful
rate shall be refunded to Borrower.  Such refund shall be made by
application of the excessive amount of interest paid against any sums
outstanding hereunder, in which event any applicable prepayment premium
shall be waived with respect to the amount so prepaid, and shall be applied
in such order as Bank may determine.  If the excessive amount of interest
paid exceeds the sums outstanding hereunder, the portion exceeding the said
sums outstanding hereunder shall be refunded in cash by Bank.  Any such
crediting or refund shall not cure or waive any default by Borrower
hereunder or under the other Loan Documents.  Borrower agrees, however,
that in determining whether or not any interest payable hereunder exceeds
the highest rate permitted by law, any non-principal amount (except

payments specifically stated herein to be "interest"), including, without
limitation, late charges, shall be deemed, to the extent permitted by law,
to be an expense, fee or indemnity rather than interest.

          (2)  In the event that for any reason one or more of the
provisions of this Fourth Replacement Revolver Note or their application to
any person or circumstance shall be held to be invalid, illegal or
unenforceable in any respect or to any extent, such provisions shall, to
such extent, be held for naught as though not herein contained but shall
nevertheless remain valid, legal and enforceable in all such other respects
and to such extent as may be permissible.  In addition, any such
invalidity, illegality or unenforceability shall not affect any other
provisions of this Fourth Replacement Revolver Note, but this Fourth
Replacement Revolver Note shall be construed as if such invalid, illegal or
unenforceable provisions had never been contained herein.

    15.  Notices.  All notices, requests, demands or other communications
to or upon the Borrower or the Bank shall be deemed to have been given or
made when hand delivered or deposited in the mail by certified mail, return
receipt requested, postage prepaid, addressed to the Borrower or the Bank,
as the case may be, at their respective  addresses as the Borrower or the
Bank may hereafter specify in writing to the other, except that any
communication with respect to a change of address shall be deemed to be
given or made when received by the Borrower or the Bank to whom such
communication was sent.

    16.  Successors and Assigns.  This Fourth Replacement Revolver Note is
binding upon the Borrower and its successors and assigns except that
Borrower shall not have the right to assign its rights or obligations
hereunder or any interest herein.

    17.  Amendment.  This Fourth Replacement Revolver Note may not be
charged orally, but only by an agreement in writing signed by the party
against whom enforcement of any waiver, change modification or discharge is
sought.

    18.  Governing Law.  This Fourth Replacement Revolver Note has been
executed and delivered in the State of New Jersey and shall be construed
and enforced in accordance with the laws of the Stat of New Jersey.

    19.  Captions.  The captions or headings of the sections in this Fourth
Replacement Revolver Note are for convenience only and shall not control or
effect the meaning or construction of any term or provision of this Fourth
Replacement Revolver Note.

    20.  Replacement Note.  This Fourth Replacement Revolver Note is a
modification and replacement of a certain Revolver Note of the Borrower to
the Bank dated October 27, 1994, the Replacement Revolver Note of the
Borrower to the Bank dated November 1, 1996, the Second Replacement
Revolver Note of the Borrower to the Bank dated October 26, 1996 [which
should have been dated 1998] and the Third Replacement Revolver Note of the
Borrower to the Bank dated October 29, 1999 (collectively, the "Original
Notes").  The indebtedness that is evidenced by this Fourth Replacement
Revolver Note represents in part the same indebtedness as that evidenced by
the Original Notes, and this Fourth Replacement Revolver Note shall not in
any way whatsoever constitute a cancellation or novation with respect to
the indebtedness evidenced by the Original Notes.


     IN WITNESS WHEREOF, the Borrower has executed this Fourth Replacement
Revolver Note as of the date and year first above written.
