and delivered in Philadelphia, PA.

     FOR VALUE  RECEIVED AND  INTENDING  TO BE LEGALLY  BOUND,  the  Undersigned
(jointly  and  severally,  if more  than  one)  promises  to pay to the order of
STANDARD  FEDERAL BANK,  NATIONAL  ASSOCIATION  (hereinafter,  together with any
holder hereof,  called  "Lender"),  at the main office of Agent (as  hereinafter
defined),  the principal sum of Five Million  Dollars  ($5,000,000.00)  plus the
aggregate  unpaid  principal  amount of all loans and advances made by Lender or
Agent to the  Undersigned (or any one of them, if more than one) pursuant to and
in  accordance  with  Subsection  2(a) of the  Loan  Agreement  (as  hereinafter
defined) in excess of such amount,  or, if less, the aggregate  unpaid principal
amount of all loans and advances made by Lender to the  Undersigned  (or any one
of them, if more than one) pursuant to and in accordance with Subsection 2(a) of
the Loan Agreement.  The Undersigned  (jointly and severally,  if more than one)
further  promises to pay interest on the outstanding  principal amount hereof on
the dates and at the rates  provided in the Loan  Agreement from the date hereof
until payment in full hereof.

     This Note is referred to in and was delivered pursuant to that certain Loan
and Security Agreement of even date herewith among LaSalle Business Credit, Inc.
("Agent"),  Lender,  the Undersigned and the Guarantors named therein (as it may
be  amended,  modified  or  supplemented  from time to time,  together  with all
exhibits  thereto,  the  "Loan  Agreement"),  and  evidences  the  Undersigned's
Liabilities in respect of Revolving  Loans.  All terms which are capitalized and
used herein  (which are not  otherwise  defined  herein)  shall have the meaning
ascribed to such terms in the Loan Agreement.

     The  outstanding  principal  balance  hereunder  and all accrued and unpaid
interest  thereon  shall be due and payable in full when and as provided  for in
the Loan Agreement.

     The Undersigned (and each one of them, if more than one) hereby  authorizes
the Agent to charge any  account of the  Undersigned  (and each one of them,  if
more than one) for all sums due hereunder.  If payment hereunder becomes due and
payable  on a  Saturday,  Sunday or legal  holiday  under the laws of the United
States  or the  Commonwealth  of  Pennsylvania,  the due date  thereof  shall be
extended to the next  succeeding  Business  Day, and  interest  shall be payable
thereon at the rate specified  during such extension.  Credit shall be given for
payments made in the manner and at the times provided in the Loan Agreement.  It
is the intent of the parties that the rates of interest and other charges to the
Undersigned  under this Note shall be lawful;  therefore,  if for any reason the
interest or other  charges  payable  hereunder are found by a court of competent
jurisdiction,  in a final  determination,  to exceed  the limit  which  Agent or
Lender may lawfully charge the Undersigned,  then the obligation to pay interest
or other charges shall automatically be reduced to such limit and, if any amount
in excess of such limit shall have been paid, then such amount shall be refunded
to the Undersigned.

Liabilities,  without notice and at any time hereafter, any indebtedness matured
or unmatured owing from Agent or Lender to the Undersigned (or any one of them).

actions) or setoff  which the  Undersigned  (or any one of them) may now have or
hereafter may have to any action by Agent and/or  Lender in enforcing  this Note
and/or any of the other  Liabilities,  or in enforcing  Agent's and/or  Lender's
rights in the Collateral and ratifies and confirms  whatever Agent and/or Lender
