Maryland corporation ("Lender"), with its principal place of business located at
525 University Avenue, Suite 700, Palo Alto, CA 94301 (the "CREDITOR"), OMRIX

BACKGROUND

Pursuant to the Loan and Security Agreement between Creditor and Customer dated
March 31, 2005 ("Loan Agreement"), the Customer has granted the Creditor a
security interest, among other things, in the Account (as defined below)
maintained by Customer at the Bank and in all funds currently or hereafter
deposited into such Account, including any interest accrued thereon. The parties
are entering into this Agreement to perfect the Creditor's security interest in
such Account. Bank is not a party to the Loan Agreement or any other agreement
between Creditor and Customer and all of Bank's rights, duties and obligations
are stated in this Account Control Agreement without reference to any other
agreement.

1. The Account. The Customer represents and warrants to the Creditor that the
Customer has established the following account at the Bank:

Account number: 605139458 (the "ACCOUNT").

As of the date hereof, the Bank is not aware of any claim to, or interest in,
the Account, except for claims and interests of the parties referred to in this
Agreement. The Customer agrees that if Customer opens any additional accounts at
the Bank, this Agreement will be deemed to have been amended to include the new
account as an Account, but only if Customer uses the same private client group
to open such additional accounts that was used to open the Account and notifies
that private client group at the time each additional account is opened that it
is subject to this Agreement. The Customer agrees that if it opens additional
accounts with the Bank, it shall be with the same private client group that was
used to open the Account.

2. Control of Accounts by Creditor

     a. The Customer and the Creditor agree that upon the occurrence of an Event
of Default (as such term is defined in the Loan Agreement), the Creditor may
deliver written instructions (the "DEFAULT ORDER") in the form attached hereto
as Exhibit A to the Bank and the Bank will, as soon as reasonably possible upon
receipt, comply with such Default Order delivered by the Creditor, without
requiring any further consent from the Customer and without regard to any
inconsistent or conflicting orders provided to the Bank by the Customer or
anyone on its behalf. Bank shall promptly confirm receipt of the Default Order
to Creditor; until Creditor receives Bank's written confirmation that the
Default Order has been received, it shall be presumed that the Default Order

was not received. For purposes hereof, "BUSINESS DAY" shall mean any day of the
year on which New York State chartered banks are required by law to be open to
the public for conducting business.

     b. It is hereby clarified that for so long as the Bank has not received a
Default Order from the Creditor, the Customer shall be fully entitled and
authorized to withdraw and deposit any and all funds available in the Accounts.

     c. Without limiting and in addition to the requirements set forth in
paragraph (a) of this Section 2, the Creditor agrees that before it attempts to
deliver a Default Order relating to the Account to the Bank, the Creditor shall
deliver to the Bank, such documentation as the Bank may, from time to time,
reasonably request, certifying the person or persons authorized by Creditor to
sign a Default Order. In absence of such documentation the Bank may rely and
shall be protected in acting or refraining from acting upon any Default Order
believed by the Bank to be genuine and to have been signed by the proper party,

3. Priority of Creditor's Security Interest: Rights Reserved by the Bank

     a. The Bank agrees that all of its present and future rights with respect
to the Account axe subordinated to the Creditor's security interest therein;
provided, however, that the Creditor agrees that the Bank expressly reserves all
of its present and future rights (whether described as rights of setoff, bankers
lien, chargeback or otherwise, and whether available to Bank under law or under
any written agreement), including, but not limited to, the right to withdraw
from the Account an amount (i) to cover the reversal of a provisional credit,
(ii) to recover funds improperly or incorrectly credited to the Account, and
(iii) to pay any Account fees or fees associated with the aforementioned. If any
