                                   Recitals

     WHEREAS, the Company holds title to certain shares of common stock, par
     value $0.01 (the "Common Stock"), of IVAX Diagnostics, Inc., a Delaware
     Corporation ("Diagnostics");

     WHEREAS, from time to time before, on and after the effective date of this
     Agreement, the Company will issue promissory notes to private investors
     (all such notes, whenever created or issued being referred to herein as the
     "Notes") in a private offering (the "Offering") pursuant to that certain
     private placement memorandum dated August 23, 2001 (the "Memorandum");

     WHEREAS, the Company has agreed to grant a security interest in certain
     shares of Common Stock of Diagnostics (the "Diagnostics Shares") in favor
     of the private investors in order to secure the payment of all Notes
     whenever issued pursuant to that certain security agreement of even date
     with this Agreement among the Agent and the Company (the "Security

     security interest in the Collateral pursuant to that certain agency
     agreement among the holders of the Investor Notes, Secured Party as agent
     for the holders of the Notes, and Debtor (the "Agency Agreement"); and

     WHEREAS, the Company has agreed to deliver the Diagnostics Shares to the

     Holders. This Agreement, the Agency Agreement, the Notes, the Security
     Agreement and all other documents and instruments executed in connection
     herewith or therewith, are collectively referred to as the "Offering
     Documents."

     NOW, THEREFORE, in consideration of the purchase of the Notes by the
private investors, the premises and the agreements herein contained, and other
good and valuable

                                       1

consideration, the receipt and sufficiency of which is hereby acknowledged,
Company, Agent and Escrow Agent hereby agree as follows:

     1.   Delivery of Diagnostics Shares.

     Upon the Final Closing of the Offering (as defined in the Memorandum), the
Company shall deliver to the Escrow Agent a number of Diagnostics Shares with an
aggregate Fair Market Value (as defined below) equal to 125% of the total
aggregate face value of the Notes purchased pursuant to the Offering. In
addition, the Company shall deliver to the Escrow Agent appropriate Stock Powers
in favor of the Holders. The delivery of the Diagnostics Shares and Stock Power
to the Escrow Agent is intended by the Parties to be a delivery of the
Diagnostics Shares to the Holders and is intended to give the Holders full
control of the delivered Diagnostics Shares, in order to perfect a security
interest as described in the Texas Business and Commerce Code.

     The "Fair Market Value" per share of Common Stock of the Diagnostics Shares
shall be equal to the average of the closing price per share of Common Stock of
Diagnostics as reported by The American Stock Exchange or such other securities
exchange, market or quotation system on which Common Stock of Diagnostics is
then listed for trading or quoted on each of the ten (10) trading days prior to
the date hereof or each Value Review Date (herein defined) as the case may be.

     2.   Terms of Escrow.

          (a) The Escrow Agent shall hold the delivered Diagnostics Shares in
escrow pending notice from the Agent directing the Escrow Agent to release the
Diagnostics Shares and Stock Power to the Company, subject to the adjustments
described below. The Company shall deliver written notice of the total amount of
Notes outstanding (the "Outstanding Note Amount") to the Agent, at least five
(5) days prior to each of the Value Review Dates, as defined in this Section 2.
On January 1, April 1, July 1, and October 1 of every year during the term of
the Notes, so long as any Notes remain outstanding (the "Value Review Dates"),
the Escrow Agent shall calculate the number of Diagnostics Shares which Fair
Market Value would equal 125% of the Outstanding Note Amount on such dates. The
Agent shall then give notice on that day, by phone, electronic mail, facsimile
or any other delivery method, to the Escrow Agent and the Company (each such
notice being referred to herein as an "Agent Notice"). Each Agent Notice shall
specify (1) the Fair Market Value per share of the Diagnostics Shares and (2)
the number of Diagnostics Shares with a Fair Market Value that is 125% of the
Outstanding Note Amount, (3) the number and Fair Market Value of Diagnostics
Shares currently held by the Escrow Agent for purposes of this Agreement, (4) if
the Fair Market Value of the Diagnostics Shares held by the Escrow Agent exceeds
125% of the Outstanding Note Amount (the "Excess Amount"), the total Excess
Amount and the number of Diagnostics Shares with a Fair Market Value equal to
the Excess Amount (the "Excess Shares"), and (5) if the Fair Market Value of the
Diagnostics Shares held by the Escrow Agent is less than the Outstanding Note
Amount ("Deficit Amount"), then the total Deficit Amount and the number of
Diagnostics Shares with a Fair Market Value equal to the Deficit Amount (the
"Deficit Shares"). The Escrow Agent shall

                                       2
<PAGE>

be entitled to rely completely on the Agent Notice and shall be under no duty
whatsoever to make any calculations regarding any of the calculations made
therein.

          (b) Upon receipt of an Agent Notice by the Company in which there is
an Excess Amount, the Company may request that the Escrow Agent deliver all or
any portion of the Excess Shares to the Company by sending a written notice of
request to be delivered to the Escrow Agent ("Company Request") within three (3)
days of a Value Review Date. Upon receipt of a Company Request, the Escrow Agent
must, as soon as practicable, deliver to the Company the requested Diagnostics
Shares and any documents necessary to relinquish any rights by the Holders in
the Excess Shares and the Agent shall execute any such documents on behalf of
the Holders.

          (c) Upon receipt of an Agent Notice by the Company in which there is a
Deficit Amount, the Company must, within three (3) days of a Value Review Date,
deliver to the Escrow Agent the total number of Deficit Shares, rounded up to
the nearest whole number.

          (d) In the event that any dispute relates to a claim by the Company
that it (i) is entitled to receive a greater number of Excess Shares or (ii) is
required to deliver a lesser number of Deficit Shares than is set forth in the
Agent Notice, the Escrow Agent may release or receive any such undisputed number
of Diagnostics Shares as is specified in the relevant Agent Notice in reliance
upon such Agent Notice.

     3.   Duties and Obligations of the Escrow Agent.

          (a) The parties hereto agree that the duties and obligations of the
Escrow Agent are only such as are herein specifically provided and no other. The
Escrow Agent's duties are as a depository only and the Escrow Agent shall incur
no liability whatsoever, except as a direct result of its willful misconduct or
gross negligence in performance of its duties hereunder. The Escrow Agent shall
have no liability whatsoever for the failure of the Agent or the Company to
perform any of their respective obligations hereunder, under the Offering
Documents or otherwise.

          (b) The Escrow Agent may consult with counsel of its choice, if it so
chooses, and shall not be liable for any action taken, suffered or omitted by it
in accordance with the advice of such counsel.

          (c) The parties acknowledge that the Escrow Agent shall not be bound
in any way by the terms of any other agreement to which the Agent and the
Company are parties, whether or not it has knowledge thereof, except as may be
required in Escrow Agent's role as a party of any such document, and the Escrow
Agent shall not in any way be required to determine whether or not any other
agreement has been complied with by the Agent or the Company, or any other party
thereto. The Escrow Agent shall not be bound by any modification, amendment,
termination, cancellation, rescission or supersession of this Agreement unless
the same shall be in writing and signed jointly by the Agent and the Company,
and agreed to in writing by the Escrow Agent.

          (d) Whenever the Escrow Agent shall be uncertain as to its duties or
rights hereunder or shall receive instructions, claims or demands which, in its
opinion, are in conflict

                                       3

until it shall be directed otherwise in writing by the Agent or by a final
judgment of a court of competent jurisdiction.

          (e) The Escrow Agent shall be fully protected in relying upon any
written notice, demand, certificate or document which it, in good faith,
believes to be genuine, including without limitation any Agent Notice. The
Escrow Agent shall not be responsible for the sufficiency or accuracy of the
form, execution, validity or genuineness of documents or securities now or
hereafter deposited hereunder, or of any endorsement thereon, or for any lack of
endorsement thereon, or for any description therein; nor shall the Escrow Agent
be responsible or liable in any respect on account of identity, authority or
rights of the persons executing or delivering or purporting to execute or
deliver any such document, security or endorsement.

          (f) The Escrow Agent shall not be required to institute legal
proceedings of any kind and shall not be required to defend any legal
proceedings which may be instituted against it or in respect of any funds,
securities or documents held in escrow pursuant to this Agreement.

notice of such resignation by mailing notice thereof to the Company and to the
Agent, and such resignation shall take effect upon the appointment of, and

The Escrow Agent may be removed after thirty (30) days' written notice by
Holders holding more than 50% of the aggregate principal amount of Notes then
outstanding by filing with the Agent and with the Company evidence of the action
in that regard taken by the Holders. If at any time the Escrow Agent (i) shall
resign or shall be removed or (ii) shall become incapable of acting, or shall be
adjudged as bankrupt or insolvent, or a receiver of the Escrow Agent or of its
property shall be appointed, or any public officer shall take charge or control
of the Escrow Agent or of this property or affairs for the purpose or
rehabilitation, conservation or liquidation, then a vacancy shall be deemed to
exist in the office of the Escrow Agent, and a successor Escrow Agent may be
appointed by Holders holding more than 50% of the aggregate principal amount of
Notes then outstanding by filing with the successor Escrow Agent, the Company
and the retiring Escrow Agent evidence of the action. If no successor Escrow
Agent shall have been appointed pursuant to the foregoing provisions of this
paragraph, and accepted appointment in accordance with this Agreement, Holders
holding more than 50% of the aggregate principal amount of Notes then
outstanding or the retiring Escrow Agent may apply to any court of competent
jurisdiction to appoint a successor Escrow Agent. Said court may thereupon after
such notice, if any, as the court may deem proper and prescribe, appoint a
successor Escrow Agent. Any resignation or removal of the Escrow Agent under
this Agreement and any appointment of a successor Escrow Agent pursuant to this
Agreement shall become effective upon acceptance of appointment by the successor
Escrow Agent. Any successor Escrow Agent appointed hereunder shall execute,
acknowledge and deliver to its predecessor Escrow Agent, and also to the Holders
and the Company an instrument accepting such appointment hereunder, and
thereupon the resignation or removal of the predecessor Escrow Agent shall
become effective and such successor Escrow Agent, without any further act, deed
or
