FOR VALUE RECEIVED, each of the undersigned, jointly and severally if more than
one (hereinafter collectively referred to as "Borrower"), promises to pay to the
order of CoreStates Bank, NA.*, a national banking association (the "Bank"), at
any of its banking offices in Pennsylvania, the principal amount of Five Million
and 00/100 DOLLARS in lawful money of the United States, or, if less, the
outstanding principal balance on all loans and advances made by Bank evidenced
by this Note ("Loans"), plus interest. Said principal and interest shall be
payable ON DEMAND

Interest shall accrue at a rate per annum which is at all times equal to the
Bank's Prime Rate. Bank's Prime Rate, such rate to change each time the Prime
Rate changes, effective on and as of the date of the change.

INTEREST-Interest shall be calculated based on a year of 360 days but shall be
charged on actual days.

Accrued interest shall be payable monthly. Accrued interest shall also be
payable on demand and when the entire principal balance of this Note is paid to
Bank. The term "Prime Rate" is defined as the rate of interest for loans
established by Bank from time to time as its prime rate. Interest shall accrue
on each disbursement hereunder from the date such disbursement is made by Bank,
provided, however, that to the extent this Note represents a replacement,
substitution, renewal or refinancing of existing indebtedness, interest shall
accrue from the date hereof. Interest shall accrue on the unpaid balance hereof
at the rate provided for in this Note until the entire unpaid balance has been
paid in full, notwithstanding the entry of any judgment against Borrower.

BANK'S LOAN RECORDS - The actual amount due and owing from time to time under
this Note shall be evidenced by Bank's books and records of receipts and
disbursements hereunder. Bank shall set up and establish an account on the books
of Bank in which will be recorded Loans evidenced hereby, payments on such Loans
and other appropriate debits and credits as provided herein, including any Loans
which represent reborrowings of amounts previously repaid. Bank shall also
record, in accordance with customary accounting practice, all other interest,
charges, expenses and other items properly chargeable to Borrower hereunder, and
other appropriate debits and credits. Such books and records of Bank shall be
presumed to be complete and accurate and shall be deemed correct, except to the
extent shown by Borrower to be manifestly erroneous.

NOTE NOT A COMMITMENT TO LEND - Borrower acknowledges and agrees that no
provision hereof, and no course of dealing by Bank in connection herewith, shall
be deemed to create or shall imply the existence of any commitment or obligation
on the part of Bank to make Loans. Except as otherwise provided in a currently
effective written agreement by Bank to make Loans, each Loan shall be made
solely at Bank's discretion.

PREPAYMENT - Borrower may at its option prepay all or any portion of the
principal balance of any Loans made hereunder at any time without premium or
penalty.

COLLATERAL - As security for all indebtedness to Bank now or hereafter incurred
by Borrower, under this Note or otherwise, Borrower grants Bank a lien upon and
security interest in any securities, instruments or other personal property of
Borrower now or hereafter in Bank's possession and in any deposit balances now
or hereafter held by Bank for Borrower's account and in all proceeds of any such
personal property or deposit balances. Such liens and security interests shall
be independent of Bank's right of setoff. This Note and the indebtedness
evidenced hereby shall be additionally secured by any lien or security interest
evidenced by a writing (whether now existing or hereafter executed) which
contains a provision to the effect that such lien or security interest is
intended to secure (a) this Note or indebtedness evidenced hereby or (b) any
category of liabilities, obligations or the indebtedness of Borrower to Bank
which includes this Note or the indebtedness evidenced hereby, and all property
subject to any such lien or security interest shall be collateral for this Note.

DEMAND NOTE - This Note is and shall be construed as a "demand instrument" under
the Uniform Commercial Code. Bank may demand payment of the indebtedness
outstanding under this Note or any portion thereof at any time.

BANK'S REMEDIES - In the event that any payment hereunder is not made when due
or demanded, Bank may, immediately or any time thereafter, exercise any or all
of its rights hereunder or under any agreement or otherwise under applicable law
against Borrower, against any person liable, either absolutely or contingently,
for payment of any indebtedness evidenced hereby, and in any collateral, and
such rights may be exercised in any order and shall not be prejudiced by any
delay in Bank's exercise thereof. At any time after such non-payment, Bank may,
at its option and upon five days written notice to Borrower, begin accruing
interest on this Note at a rate not to exceed five percent (5%) per annum in
excess of the rate of interest provided for above on the unpaid principal
balance hereof; provided, however, that no such interest shall accrue hereunder
in excess of the maximum rate permitted by law. All such additional interest
shall be payable upon demand.

NOTICE TO BORROWER - Any notice required to be given by Bank under the
provisions of this Note shall be effective as to each Borrower when addressed to
Borrower and deposited in the mail, postage prepaid, for delivery by first class
mail at Borrower's mailing address as it appears on Bank's records.

DISBURSEMENTS AND PAYMENTS - The proceeds of any Loan may be credited by Bank to
the deposit account of Borrower or disbursed in any other manner requested by
Borrower and approved by Bank. All payments due under this Note are to be made

payment shall not be deemed to have been made until the funds comprising such
payment have actually been received by or made available to Bank. If Borrower is
not an individual, Borrower authorizes Bank (but Bank shall have no obligation)
to charge any deposit account in Borrower's name at Bank for any and all
payments of principal, interest, or any other amounts due under this Note.
