Note in writing of the occurrence of a Blockage Event; provided, that,
notwithstanding anything to the contrary in this Note), the failure of the
Company to so notify the holder of this Note of the occurrence of a Blockage
Event shall have no effect on the obligations of the Company or the holder of
this Note during the continuance of such Blockage Event as set forth therein.
Upon termination of a Blockage Event (so long as no other Blockage Event has
occurred and is continuing or would occur as a result thereof), the Company
shall resume making payments pursuant to the terms and conditions of this Note.

          (e)   Any amendment or modification of the terms of Section 3 of this

trust for the benefit of, and shall be immediately paid over or delivered or
transferred to, the holders of Superior Debt or their duly appointed agents for

Debt shall be deemed not to be a payment on this Note for any reason whatsoever
and the indebtedness under this Note shall remain as if such erroneous payment
had never been paid by the Company or received by the holder of this Note.  In
the event of the failure of any holder of this Note to endorse or assign any
such payment, distribution or security, each holder of any Superior Debt is
hereby irrevocably authorized to endorse or assign the same.

the terms of this Note, or exercise or continue to exercise any other right or
remedy at law or equity that such holder might otherwise possess, to collect any
amount due and payable in respect of this Note, including, without limitation,
the acceleration of this Note (and if this Note has already been accelerated,
the holder will, immediately upon becoming aware of the occurrence of such
Blockage Event or Event of Default, reverse such acceleration), the commencement
of any foreclosure on any lien or security interest, the filing of any petition
in bankruptcy or the taking advantage of any other insolvency law of any
jurisdiction, unless and until the Superior Debt shall have been fully and
finally paid, in cash, and satisfied, unless one or more of the holders of the
Bank Debt shall have accelerated the maturity of the Bank Debt, or if no Bank
Debt is outstanding, unless one or more of the holders of other Superior Debt
shall have accelerated the maturity thereof, in an amount in excess of
$1,000,000, in which case the holder of this Note shall be entitled to
accelerate the maturity hereof but shall not be entitled to take any other
action described above and, provided further, that the holder of this Note
acknowledges and agrees that the acceleration of this Note shall immediately be
reversed if and when (A) one or more holders of Superior Debt take similar
action which results in the aggregate amount of Superior Debt to be accelerated
to be less than $5,000,000 or (B) such Superior Debt is fully and finally paid
in cash. Notwithstanding the foregoing or any permissible action taken by the
holder of this Note, the holder of this Note shall not be entitled to receive
any payment in contravention of the other provisions of this Section 3,

would otherwise have been entitled but for the provisions of this Section 3
                                                                  ---------

of this Note (A) following payment in full of the Superior Debt in cash, shall
be entitled to receive any and all further payments or distributions applicable
to Superior Debt, and (B) following payment in full of the Superior Debt in
cash, shall be subrogated to the rights of the holders of the Superior Debt to
receive distributions applicable to the Superior Debt, in each case until this
Note shall have been paid in full in cash or such other consideration acceptable
to the Holder of this Note in its sole discretion.  If any holder of this Note
has been subrogated to the rights of the holders of Superior Debt due to the
operation of this Section 3(j), the Company agrees to take all such reasonable
                  ------------

unconditional, to pay to the holder the principal and interest on this Note as

intended to or will affect the relative rights of the holder of this Note and
creditors of the Company other than the holders of the Superior Debt,  nor,

               ----------

          (i)  the Company fails to pay when due and payable (whether
     at maturity or otherwise) the full amount of interest then
     accrued on any Note or the full amount of any principal payment
     on any Note, and such failure to pay is not cured within thirty
     business days after the occurrence thereof; or

           (ii) the Company makes an assignment for the benefit of
     creditors or admits in writing its inability to pay its debts
     generally as they become due; or an order, judgment or decree is
     entered adjudicating the Company bankrupt or insolvent; or any
     order for relief with respect to the Company is entered under the
     Federal Bankruptcy Code; or the Company petitions or applies to

     relating to the Company under any bankruptcy reorganization,
     arrangement, insolvency, readjustment of debt, dissolution or

     subsequent increases pursuant to this subparagraph).

     immediately due and payable and may demand immediate payment of
     all or any portion of the outstanding principal amount of the
     Notes (together with all such other amounts then due and
     payable). The Company shall give prompt written notice of any
     such demand to the other holders of Notes, each of which may
     demand immediate payment of all or any portion of such holder's
     Note. If any holder or holders of the Notes demand immediate
     payment of all or any portion of the Notes, the Company shall
     immediately pay to such holder or holders all amounts due and
     payable with respect to such Notes.

          (iii) If an Event of Default of the type described in
     Section 4(a)(ii) has occurred, the aggregate principal amount of

     immediately due and payable without any action on the part of the
     holders of the Notes, and the Company shall immediately pay to
     the holders of the Notes all amounts due and payable with respect
     to the Notes.

          (iv)  Each holder of the Notes shall also have any other
     rights which such holder may have been afforded under any
     contract or agreement at any time and any other rights which such
     holder may have pursuant to applicable law.

          (v)   The Company hereby waives diligence, presentment,
     protest and demand and notice of protest and demand, dishonor and
     nonpayment of this Note,

                                      -6-

 
     and expressly agrees that this Note, or any payment hereunder,
     may be extended from time to time and that the holder hereof may
     accept security for this Note or release security for this Note,
