application 09/000,917, which is the parent application of US letters patent
6,245,038 issued June 12, 2001 (the "Patent").

     WHEREAS, Borberg assigned all his right, title and interest to the Patent
and the Patent Rights to Dr. Hans Stock ("Stock");

     WHEREAS, Stock originally licensed any and all of his rights, title and
interests to the Patent and the Patent Rights to the Licensee in an undocumented
oral agreement;

     WHEREAS, Stock executed a patent license and royalty agreement with
Licensee as of August 6, 2004 and amended and restated that agreement as of the
date hereof;

     WHEREAS, Brunner executed a patent license and royalty agreement with a
predecessor of the Licensee as of May 6, 2002 and amended and restated that
agreement as of the date hereof;

     WHEREAS, Brunner continues to desire to license any and all of his rights,
title and interest to the Patent and the Patent Rights derived therefrom to
Licensee, and

     WHEREAS, Licensee continues to desire to obtain an exclusive license to all
of Brunner's interest in the Patent and the Patent Rights derived therefrom and
to exclusively own the License to any and all of his rights, title, interests
and ownership to the Patent and any and all related patents, rights and
inventions that specifically relate to the Patent whether owned now or at any
time in the future by Brunner (the "License"), and

     WHEREAS, Brunner shall be eligible to receive any and all consideration and
compensation from the Licensee, such as those pledged to be made by the Licensee
to Brunner under the terms of this Agreement.

     NOW THEREFORE, in consideration for guaranteed Advance Royalty Payments and
Royalty Payments as described below, and other good and valuable consideration,
the parties agree as follows:

1.   Patent Rights. Shall mean any and all of Brunner's rights, title, ownership
     and interests in and to US letters patent 6,245,038 and any and all
     inventions, modifications, continuations-in-part, extensions, divisions,
     improvements, etc. made by Brunner or his agents, in any and all areas that
     relate directly to the Patent, regardless of whether such inventions or
     improvements are patentable or may become patented; all inventions,
     modifications, continuations-in-part, extensions, divisions, improvements,
     etc. shall automatically be incorporated herein without the payment of any
     additional fees, royalties or any other compensation or considerations of
     any kind.

2.   License Grant. Brunner confirms that he has exclusively licensed, and does
     hereby continue to exclusively license, in accordance with the terms set
     forth below, unto Licensee, Brunner's entire undivided right, title,
     ownership and interest in and to the Patent and the Patent Rights,
     throughout the Territory, to be held and enjoyed by Licensee the same as it
     would have been held and enjoyed by Brunner if this Patent License and
     Royalty Agreement had not been made and entered into. The exclusive license
     granted herein also includes an exclusive right for the Licensee to grant
     expressly or implicitly, directly or through its subsidiaries or
     affiliates, sublicenses to the Patent and the Patent Rights without the
     requirement to pay any additional royalty fee or sublicense fee to Brunner,
     to end users of the patented method including medical practitioners and
     medical clinics.

     The exclusive license granted herein also includes an exclusive right for
     the Licensee to grant sublicenses to the Patent and the Patent Rights to
     unaffiliated third parties other than the end users referred to
     hereinbefore. The Licensee acknowledges that such sublicensee shall not
     have the right to grant sub-sublicenses to the Patent and the Patent Rights
     unless consented to in writing by Brunner; sub-sublicensing to end-users as
     defined in the paragraph above is, however, permitted without consent.

     Brunner recognizes that by signing this Agreement, the combination of this
     Agreement and a patent license and royalty agreement between Stock and
     Licensee will collectively constitute an EXCLUSIVE PATENT LICENSE AND
     ROYALTY AGREEMENT by which Brunner and Stock grant an exclusive license in
     the Patent to Licensee including the right to sue for past infringement.

3.   Representation by Brunner. Brunner warrants that he, along with Borberg, as
     the joint inventors of United States Patent 6,245,038, exclusively owns and
     possesses the Patent and the Patent Rights, and has all right and title
     thereto and that this Patent License and Royalty Agreement is made without
     encumbrance or threat of future interference by others claiming ownership
     therein and that no security interests to any third party exists therein or
     any other agreement to the contrary.

4.   Representation by Licensee. Licensee represents that it is a bona fide
     corporation in good standing in Delaware.

5.   Advance Royalty Payments. Licensee agrees to pay Brunner Fifty Thousand
     Dollars ($50,000 USD) annually as an advance and credited against any and
     all Royalty Payments paid in accordance with this Agreement. Such Advance
     Royalty Payments shall be non-refundable and be paid to Brunner and in
     equal payments of Twelve Thousand Five-hundred Dollars ($12,500 USD), made
     quarterly, on or before the expiration of Forty-five (45) days after the
     reporting close of each prior calendar quarter.

6.   Royalty Payments. Licensee agrees to pay royalties to Brunner totaling One-
     Half Percent (0.5% in USD). Royalty Payments shall be non-refundable and be
     calculated and paid based upon Total Net Revenues that Licensee, or any
     subsidiary of licensee or any company affiliated with licensee receives
     from the bona fide commercial sales of its



<PAGE>
                                     - 3 -


     Products sold in reliance and dependence upon the validity of the Patent's
     claims and of the Patent Rights in the Territory.

7.   Sublicense Fee. In instances where Brunner has consented to a sublicense to
     the Patent and the Patent Rights from Licensee to a third party who is not
     an end user of the patented method, Licensee agrees to pay to Brunner a
     sublicense fee constituting a non-refundable cash payment equal to
     Twelve-and-a-Half Percent (12,5% in USD) of any:

     (i)   Upfront cash payment made to Licensee in consideration of the
           sublicense;

     (ii)  Sublicense fees received by Licensee in consideration of the
           sublicense;

     (iii) Premium over the fair market value of equity investments in Licensee
           in consideration of the sublicense; and

     (iv)  Non-cash consideration received by Licensee from a sublicense in
           consideration of the sublicense, such consideration to include,
           without limitation, equity in other companies and the value of any
           license granted to Licensee.

8.   Accounting and Timing of Royalty Payments and of payments of Sublicense
     Fees. Upon making each Royalty and Sublicense Fee Payment, Licensee shall
     provide Brunner with a summary of the accounting used to determine the
     amount of Royalty Payment and Sublicense Fees due. Royalty Payments and
     Payments of Sublicense Fees shall be made by wire transfer and shall be
     computed on Total Net Revenues received by the Licensee by the reporting
     close of each calendar quarter and distributed and paid to Brunner and on a
     quarterly basis, on or before the expiration of Forty-five (45) days after
     the reporting close of each prior calendar quarter.

9.   Failure to Pay by Licensee. Should Licensee fail to make any payments as
     required herein, and should the Licensee fail to cure the breach created
     thereby, any and all rights, title and ownership to the License provided to
     the Licensee under this Agreement shall be forfeited and any and all such
     rights, title and ownership to the License shall, upon notice of the
     failure to cure the breach, immediately revert to Brunner, and all monies
     paid by Licensee until such date shall be retained by him without
     forfeiture.

10.  Territory. Shall mean the United States and any other jurisdictions subject
     to recognizing any valid claims of the Patent or of the Patent Rights.

11.  Total Net Revenues. Shall mean total gross revenues less any discounts,
     rebates, shipping costs, handling costs, transportation insurance costs,
     importation fees, and duties on any and all Products sold by the Licensee
     in the Territory which are sold in reliance upon and which are specifically
     used for extracorporeal therapies for the treatment of ophthalmic diseases
     in accordance with or subject to any of the valid claims of the Patent. In
     the case of sales of filters for ophthalmic treatment within the meaning of
     the Patent, either directly by Licensee or through Licensee's subsidiaries
     or a company affiliated with Licensee, such total gross revenues shall be
     deemed to be the cost of the filters to



<PAGE>
                                     - 4 -


     Licensee; or in case of Products having components in addition to said
     filters, the allocated cost of the filters to Licensee relative to the
     total costs of said Products. For other Products the Total Net Revenues
     shall be the actual sales price to purchasers of the Products, less any of
     the discounts etc. as mentioned above.

12.  Records. Licensee agrees to keep complete and correct books, accounts and
     records according to Generally Accepted Accounting Principles (GAAP)
     regulations to facilitate computation of Royalty Payments and Sublicense
     Fees. Brunner or his representatives acceptable to Licensee, shall have a
     full right of accounting including the right to confidentially examine
     Licensee's books and records, at all reasonable times and upon reasonable
     notice, for the purpose of verifying the amount of Royalty Payments due. In
     case of miscalculations elicited by such examination, Licensee shall
     compensate Brunner for the agreed upon shortfall within thirty (30) days of
     receipt of a detailed report outlining the Royalty Payments determined to
     be due. In case the shortfall exceeds 5% or US$ 5.000, whichever is
     greater, Licensee shall reimburse Brunner's costs for the examination.

13.  Products. Shall mean any filters, tubing sets or pumps sold by Licensee or
     its subsidiaries or affiliates to unaffiliated third parties in the
     Territory for the purposes of providing extracorporeal therapies for the
     treatment of the ophthalmic diseases as defined by any valid claim(s) of
     the Patent.

14.  Term and Termination. The Royalty Payments shall be due to Brunner
     beginning with the first bona fide commercial sale of any Product in the
     Territory and may, at the discretion of Licensee terminate upon the first
     of any of the following three events to occur: (a) all patents of the
     Patent Rights expire; (b) all material patent claims of the Patent Rights
     are determined, in the opinion of an experienced patent attorney approved
     by Brunner and Licensee or an independent experienced patent attorney
     selected by the American Arbitration Association in accordance with its
     rules if such joint approval cannot be obtained after thirty (30) days, to
     be invalid or unenforceable; or (c) a similarly fashioned competitive
     extracorporeal product, method or technology is commercially introduced in
     the Territory for use in ophthalmic indications that could not be deterred
     by best-efforts enforcement/infringement proceedings brought by Licensee
     against the competitive product, method or technology where such
     proceedings are made in reliance in full or in part upon the Patent's
     claims and or the Patent Rights.

     "material patent claims" within the meaning of this section of the
     Agreement are those claims of the Patent Rights covering a method for the
     effective therapeutic treatment of Age-related Macular Degeneration (AMD)
     using plasma differential separation techniques.

     Either Party may terminate this Agreement in the event of a material breach
     by the other Party that is not addressed elsewhere in this Agreement,
     provided only if the breaching Party is given Notice of the breach and a
     reasonable time, not to exceed thirty (30) days from the date of receipt of
     such Notice, in which to cure such breach. Brunner may further terminate
     this Agreement in case of a final court order of bankruptcy or insolvency
     of Licensee, and in case Licensee refuses to defend and/or enforce the
     Patent



<PAGE>
                                     - 5 -


     (which defence or enforcement may include a license or other reasonable
     settlement) as provided under section 15. In the case of bankruptcy or
     insolvency of Brunner the Licensee shall retain its rights to the Patent
     and the Patent Rights in accordance with the terms of this agreement.

     The right of Brunner to receive the royalty payments and Sublicense Fees
     under sections 5, 6 and 7 shall survive the death of Brunner and shall
     become a receivable of Brunner's estate until the termination of this
     agreement.

15.  Patent Defense. Licensee shall pay for any and all costs incurred for
     patent maintenance, enforcement and defense of the Patent or the Patent
     Rights in the Territory other than re-examination costs as noted below.
     Brunner may, at his own expense, join with the Licensee in the enforcement
     or the defense of the Patent or the Patent Rights in the Territory. In case
     Licensee, after due consideration expressly indicates its refusal in
     writing to Brunner to enforce or defend the Patent or the Patent Rights in
     the Territory then Brunner may take his own steps to enforce or defend the
     Patent at his own expense. Brunner has no obligation for such
     participation, defense or enforcement at own expenses. Licensee may deduct
     the allocated costs for one reexamination procedure of US letters patent
     6,245,038 incurred under this section 14 from future Royalty Payments and
     Sublicense Fees payable to Brunner under sections 6 and 7.

16.  Participation. Brunner agrees, in consideration of the premises herein,
     that his executors and administrators will, at any time upon request,
     communicate to the Licensee, its successors and assigns, any facts relating
     to said Patent and Patent Rights, and the history thereof, known to him or
     his successors and assigns, and that he will testify as to the same in any
     interference or other proceeding when requested to do so by the Licensee,
     its successors and assigns. Any and all costs of such participation by
     Brunner or his successors and assigns shall be borne by Licensee.

17.  Succession. Brunner binds himself and his heirs, executors, administrators,
     employees and legal representatives, as the case may be, to execute and
     deliver to the Licensee, any further documents or instruments and to do any
     and all further acts that may be deemed necessary by the Licensee (i) in
     connection with any aspect of the re-examination proceedings, (ii) in
     connection with any proceedings to enforce or defend the Patent; (iii) to
     file applications for improvements and inventions in any country where
     Licensee may elect to file such application(s), and (iv) that may be
     necessary to vest in the Licensee, the license, rights or title herein
     conveyed, or intended so to be, and to enable such title to be recorded in
     the United States and or foreign countries where such application(s) may be
     filed. Any and all costs of such participation by Brunner or his successors
     and assigns shall be borne by Licensee.

18.  Relationship of the Parties: Indemnification. It is agreed that this
     Agreement does not make any Party herein a general or special agent, legal
     representative, subsidiary, joint venturer, partner, employee or servant of
     any other Party herein for any purpose.

19.  Validity. During the time of this agreement, licensee will not challenge
     the validity of the patent rights at court or with patent authorities, or
     will support third parties in such a



<PAGE>
                                     - 6 -


     challenge. The parties acknowledge that the re-examination proceedings
     shall not be considered a challenge of the Patent Rights.

20.  Breach and Disputes. Any breaching Party shall have Thirty (30) Days from
     the date of notification to cure such breach. Any dispute between the
     Parties to this Agreement shall be resolved through binding arbitration,
     which shall be governed under the rules and regulations of the American
     Arbitration Association.

21.  Forum, Venue and Governing Law. This agreement shall be governed and
     interpreted under Delaware law (without applying its conflict of law
     principles). Exclusive venue for legal proceedings arising hereunder shall
     be in New York, New York.

22.  Entire Agreement. This Agreement supersedes any prior understanding that
     may have been reached between the Parties and encompasses the entire
     agreement between the Licensee and Brunner with respect to the Patent and
     the Patent Rights. The terms of this Agreement are confidential and shall
     be maintained by the Parties in accordance thereby.

23.  Modification. This Agreement cannot be modified except in writing executed
     mutually between the Parties.

24.  Assignment. Licensee shall not grant, transfer, convey or otherwise assign
     any of its rights under this Agreement without the express consent in
     writing of Brunner.

     IN WITNESS WHEREOF, the Parties have signed and executed this Agreement and
have caused this Agreement to become effective as of the Effective Date last
