                                  -----------

          2.1  Security Agreement. If the Nelson/Levy Notes are outstanding on
               ------------------
March 1, 2000, Caprius will grant to the Holder a joint security interest with
the holders of the other outstanding Nelson/Levy Notes in the inventory,
receivables and non-leased equipment of the Strax Division of the Company.
Such security interest shall be pursuant to the terms of a Security Agreement
to be executed among the initial holders of the Nelson/Levy Notes and the
Company and shall become effective only if the Nelson/Levy Notes are
outstanding on March 1, 2000. Between December 28, 1999 and March 1, 2000, the
Company will not grant a security interest to a third party in the assets of
the Strax Division, except (i) in connection with a transaction on which the
net proceeds will be used to prepay all or a portion of the then outstanding
principal and accrued interest on the Nelson/Levy Notes pursuant to Section 3.3
hereof or (ii) in connection with an installment purchase or a capitalized
lease of equipment.

                             3. PREPAYMENT OF NOTE
                             ---------------------

          3.1  Note to Be Callable for Prepayment. The Company shall have the
               ----------------------------------
right, subject to compliance with the provisions of this Article 3, to call
this Note for prepayment at any time (herein referred to as the "Prepayment
Date"), either in whole or in part, at the principal amount so to be prepaid,
together with accrued interest thereon to the Prepayment Date. Any prepayment
on this Note shall be proportionate to a simultaneous prepayment on the other
Nelson/Levy Notes.

          3.2  Notice of Call for Prepayment. Notice of call for prepayment of
               -----------------------------
this Note or any portion hereof shall be given to the Holder of Record at his
address in accordance with Section 7.2 hereof at least three (3) Business Days
prior to the Prepayment Date. Upon notice of call for prepayment being given as
aforesaid, the Company shall prepay on the Prepayment Date the entire principal
amount of this Note or the portion hereof, as the case may be, so called for
prepayment as hereinabove provided, and shall pay all accrued and unpaid
interest on the principal amount being prepaid.

          3.3  Sale of the Strax Division. (a) If the Company shall sell or
               --------------------------
otherwise dispose of the Strax Division (the "Strax Sale") prior to the
Maturity of this Note, the Company shall apply the net cash proceeds of such
Sale (after payment of all commissions, expenses and taxes related to such
Sale) toward prepayment of the Nelson/Levy Notes and the Bridge Notes (if they
are still outstanding) in accordance with this Article 3.


                                       2
<PAGE>


               (b)  If the net cash proceeds to be received by the Company on a
Strax Sale would be insufficient to pay the outstanding amounts on the
Nelson/Levy Notes and the outstanding Bridge Notes, the Holders of Record of
more than 50% of the outstanding principal amount of the Nelson/Levy Notes must
consent to such Sale. The net cash proceeds from the Strax Sale shall be paid
on a pro rata basis among the outstanding indebtedness on the Nelson/Levy Notes
and the Bridge Notes in accordance with Section 3.3(c) hereof, and the
remaining principal amounts on the Nelson/Levy Notes shall be payable on
September 1, 2000. The Company and the Holders of Record of the Nelson/Levy
Notes shall use their respective best efforts to reach agreement to secure such
remaining principal amounts.

               (c)  The Company shall effect the prepayment required by this
Section within ten (10) Business Days after its receipt of the net proceeds
from the Strax Sale. If less than the entire principal amount of the
Nelson/Levy Notes and the Bridge Notes at the time outstanding shall be called
for prepayment, upon the Strax Sale in accordance with Section 3.3(b) hereof,
the Company shall allocate the principal amount so called for prepayment among
the Holders of the Nelson/Levy and Bridge Notes in proportion, as nearly as may
be, to the aggregate principal amount of Notes then held by the respective
holders thereof. In any such allocation (i) the Company may, according to such
method as it shall deem proper in its discretion, make such adjustments by
increasing or decreasing by not more than $1,000 the amount which would be
allocable on the basis of exact proportion to any holders, as may be necessary
to the end that the principal amount so allocated shall be in each instance an
integral multiple of $1,000 and (ii) the Company shall not be required to
allocate any amount to any holder to which the amount allocable on the basis
of the exact proportion would be less than $1,000.

          3.4  Prepayment of Portion of Note. Upon any prepayment of a portion
               -----------------------------
of the principal amount of this Note, the Holder, at his option, (i) may
require the Company to execute and deliver at the expense of the Company a new
Note dated as of the date to which interest on this Note has been paid, and
payable to such person or persons as may be designated by the Holder, for the
aggregate principal amount of this Note then remaining unpaid, upon surrender
of this Note and payment of applicable transfer taxes, if any, or (ii) may
present this Note to the Company for notation hereon of the payment of the
portion of the principal amount of this Note so prepaid.

                          4. COVENANTS OF THE COMPANY
                          ---------------------------

exchange and where notices and demands to or upon the Company in respect of

due and payable, and thereupon such balance, including the principal of this
Note and accrued interest thereon, shall become so due and payable without
presentation, protest or further demand or notice of any kind, all of which are

          5.2  Enforcement of Remedies. In case any one or more of the Events
               -----------------------
of Default specified in Section 5.1 hereof shall have occurred and be
continuing, the Holder may proceed to protect and enforce his rights either by

Default in connection therewith may be waived otherwise than by a written
instrument signed by the Holder. Any provision of this Note to the contrary
notwithstanding, changes in or additions to this Note may be made, and
