(2)   OMRIX BIOPHARMACEUTICALS LTD., (Hereinafter "OMRIX")

This agreement is an addendum to the Agreement between the parties entered into
on April 1997, as amended from time to time "THE AGREEMENT". This addendum to
the Agreement will be called hereinafter "THE ADDENDUM".

Following negotiations between the parties it has been agreed between the
parties as follows;

1.    The parties acknowledge that the total debt of Omrix to MDA as of 31.12.03
      amounts to *** million USD.

2.    MDA accepts the requests and the arguments of Omrix for the set-off of the
      amount of *** million USD from the outstanding debt of Omrix indicated
      in Section 1 above, as detailed herein below:

      2.1.  *** million USD - participation of MDA in "Compulsory Investments"
            (as defined in the Agreement) made by Omrix until the day of
            31.12.03.

      2.2.  *** million USD for inadequate plasma sold by MDA to Omrix.

      2.3.  *** million USD - an amount to which MDA is entitled, according to
            the terms of the Agreement as a "FDA bonus" - the right to which MDA
            hereby waves.

3.    (a)   Omrix has provided MDA with a list of equipment purchased by
            Omrix for purposes of manufacturing, in the value of 1.5 million
            USD, which MDA does not accept to be part of Compulsory Investments.
            The part of this equipment which is subject to the terms of
            subsection (b) herein below in respect of the "Glue Equipment" as
            herein below defined, will be transferred to the ownership of MDA
            subject to the terms detailed in section (b) below (hereinafter:
            "THE EQUIPMENT LIST"). MDA is ready, subject to the provisions of
            the Addendum, to accept that an amount of 1.150 million USD out of
            the value of the items on the "Equipment List" are items that are
            part of "the Compulsory Investment" as defined in the Agreement.

      (b)   In addition, it is agreed that out of the Equipment List, MDA will
            have an option to buy equipment in return for *** USD. Such
            equipment which has been designated solely for the manufacturing of

            glue (Hereinafter: "the Glue Equipment") and which was identified by
            the parties in the attachment to the Addendum. The amount of ***
            USD, will be deducted from the debt of Omrix at the end of the rent
            period (31.12.2007). For the avoidance of doubt, if Omrix stays in
            the plant, after 1.1.2008, Omrix shall have the option to sell the
            Glue Equipment to MDA at said price, provided that the license for
            the manufacturing of biological glue which was promised to MDA in
            the Agreement, will be granted by Omrix to MDA, and Provided further
            that until that date an agreement between MDA and Omrix with respect
            to cooperation in additional subjects shall have been reached.

4.    In view of the above, it is agreed that the total amount due to MDA from
      Omrix as of 31.12.03 shall be *** million USD payable as follows:

      4.1.  *** million USD in the year of 2004.

      4.2.  *** million USD in the year of 2005.

      4.3.  The balance in the amount of *** USD shall be paid in four
            equal, annual installments of *** USD each starting in the year
            2007, provided, however, that if Omrix leaves the plant before the
            above amount is fully paid, then the balance of the above amount due
            then shall be payable immediately

5.    THE RENT

      Notwithstanding the provisions of the Agreement and of the Addendum dated
      March 26th, 2003, the rent that Omrix shall be liable to pay as from
      1.1.04 will be as follows:

      (a)   For the year 2004 Omrix shall pay the rent in the amount of 700,000
            USD plus an amount being *** of the overall net turnover of the sale
            of products by Omrix to third parties (including also biological
            glue and products which are not "Licensed Products" as defined in
            the Agreement) that will be sold during the year of 2004.

            In this respect, the "total net sales turnover" shall mean the sales
            to third parties of all the products of any kind which Omrix has
            sold in the course of 2004 (without VAT), after deduction of
            commercial reductions given to third parties, returned products and
            credits for damaged goods which will be given or paid to third
            parties. In this respect, a mother company, an affiliated company or
            any other business that Omrix is a partner in shall not be deemed
            to be "third parties".

      (b)   As of January 1st 2005 Omrix shall pay MDA yearly rent in the amount
            of 700,000 USD per annum plus an amount being *** from the overall
            net turnover sales of the products (as defined in subsection (a)
            above), but not less than $1.1 million and not more than 2 million
            USD, in one year.

                                       2

      (c)   It is agreed that payments based on turnover as indicated in
            subsections (a) and (b) above, shall be paid twice a year, on June
            30th and on December 31st each year, accompanied by sales reports.
            If it appears that the sales turnover was different from what was
            expected according to the actual payments, the final payment for
            each year shall be determined until March 31st of the calendar year
            thereafter.

6.    THE TERM OF THE LEASE

      (a)   Notwithstanding the provisions of the Agreement, the term of the
            lease of Omrix shall terminate on 31.12.2010.

      (b)   Notwithstanding the aforesaid in subsection (a) above and subject to
            the provisions of subsection (c) herein below, Omrix shall be
            entitled to terminate the lease by giving a written notice to MDA,
            12 months in advance, provided however that the lease will not end
            before 31.12.2007.

      (c)   If Omrix exercises its right to terminate the lease before
            31.12.2010, as aforesaid, and leaves the plant before that date -
            Omrix shall be liable to pay MDA an amount of 500,000 USD for each
            year as from the date of the actual termination of the lease and
            until 31.12.2010 (for parts of a year - the proportional part of
            500,000 USD), and shall be exempted from paying rent and from all
            other obligations and undertakings towards MDA as stipulated in the
            Agreement and for the period starting from Omrix' actual eviction of
            the premises.

7.    THE PLASMA PRICE

      (a)   As from 1.1.2004, Omrix will pay MDA for Fresh Frozen Plasma ***,
            instead of ***, and for frozen Plasma it will pay ***, instead of
            ***. As from 1.1.05, Omrix will be permitted to notify MDA at the
            beginning of each quarter, what are the components of plasma which
            it intends to use for the actual production of final products. If
            MDA does not exercise its rights according to section 7(b) herein
            below, there will be made an accounting, once for each two quarters,
            and Omrix shall pay MDA the proper proportional price, for those
            components of plasma which shall have actually been used for
            manufacturing. In addition, if Omrix manufactures additional
            products (which are not included in the Licensed Products) the price
            of the plasma shall be accordingly increased. For the avoidance of
            doubt it is hereby clarified that if Omrix exercises its right
            herein above, the proportional price for those components of plasma,
            which are to be used by Omrix as aforesaid, shall be fixed in
            proportion to the price of *** of fresh frozen plasma and *** of
            frozen plasma.

      (b)   Notwithstanding the aforesaid in subsection 7(a), in the event MDA
            succeeds in finding a buyer for its plasma ready to pay higher
            prices then

                                        3
<PAGE>

            the prices mentioned in subsection 7(a) above, Omrix will have the
            option to purchase from MDA the plasma for the same prices which
            said third party is ready to pay, by giving a notice in writing to
            MDA to that effect not later than 15 days after receiving a written
            letter from MDA in which MDA states the prices offered by third
            party.

8.    MDA is ready to purchase from Omrix approximately 2 tons of pasta for the
      manufacturing of Albumin and 150 kg of the final product of Albumin, both
      of which their expiry date will not be before June 30st 2005, at a total
      price of ***. The transaction will take place before the end of 2004.

9.    Without derogating from the obligations of the parties under the Agreement
      for the maintenance of the Systems as defined therein, it is agreed, that
      the following maintenance or repair works in that Plant shall be born by
      MDA, in the following events:

      a.    The official standard of a certain equipment in the building of the
            Plant or in relation to some appliances permanently connected to the
            walls have been changed, so that it is obligatory to amend it or to
            replace some parts in it.

      b.    There is a permanent shortage of spare parts for a certain equipment
            or system, being permanent and inseparable part of the building,
            e.g. an electricity, water, sewage, which prevent the proper
            operation of the system to which it belongs.

      c.    There is damage to the building of the Plant, which is not the
            result of a wear and tear caused by the use of the Plant by Omrix
            and in which is not included in the day-to-day maintenance work.

      d.    There is a breakdown of a system or a component, even if it does not
            fall in the meaning of the term "System", as defined in the
            Agreement, provided it was originally built or erected by MDA
            designated solely for the Plant and the breakdown is not the result
            of a negligent or intentional action of Omrix or any of its
            employees or subcontractors.

      e.    The obligation of MDA to finance or to pay the maintenance or repair
            works as per subsections b and d shall not exceed the amount of
            100,000$ in one calendar year, unless and to the extend the rent
            paid to MDA in such a year exceeds 1,300,000$. It is further
            clarified that MDA will not have to pay for any repairs or
            maintenance work unless it certifies in advance such payment. In the
            event of urgent work Omrix may execute it without a prior approval
            provided that in such a case MDA will not be responsible for more
            than 10.000$.

10.   The parties will examine positively the possibility to construct in the
      area of the blood services a plant for biological glue, both from the
      point of view of the laws of town planning and environmental requirements,
      and from the point of view of the required investment and its financing
      and also from the point of view of payments that should be made to MDA.
