                                                                   EXHIBIT 10.10


                             MANUFACTURING AGREEMENT

                                     Between

OPOCRIN S.P.A. - having its registered office at via Pacinotti, 3 - 41040 Corlo
di Formigine (Modena) Italy - Via Pacinotti 3 thereinafter referred to as
OPOCRIN)

                                      and

PARTEC having its registered office at 216 Jaffa Road, Jerusalem 94383 Israel
(thereinafter referred to as PARTEC)

(together called PARTIES)

have agreed, on 16 April 1999, as follows:

                                    WHEREAS

OPOCRIN is an Italian firm which has been producing for many years biological
products in bulk from animal glands and tissues. One of these products is
porcine Sulodexide (Glucuronylglucosaminglycansulphate) . ("DS") which OPOCRIN
has been supplying ALFA WASSERMANN (thereinafter referred to as ALFA) for its
specialty VESSEL, since the date of its commercialization.

PARTEC is an Israeli company specialized in the development and marketing of
biopharmaceutical products and is interested in buying DS from OPOCRIN pursuant
to the terms set forth in this Agreement for a product to be registered,
approved and marketed throughout the world (hereinafter referred to as the
TERRITORY).

                  NOW, THEREFORE, THE PARTIES AGREE AS FOLLOWS:

PRODUCTION

         1.  OPOCRIN agrees to manufacture and PARTEC agrees to purchase amounts
             of DS as PARTEC shall order from time to time for sale by PARTEC,
             or its licensees, affiliates or partners, in the TERRITORY. OPOCRIN
             may, subject to PARTEC's prior written agreement, procure the
             supply of DS to PARTEC from a third party, provided that such
             supply of DS shall conform in all respects to the requirements set
             forth in this Agreement. Partec shall purchase, at a minimum,
             amounts of DS from Opocrin sufficient to meet its needs for all
             clinical trials of Sulodexide during the term of this Agreement.
             Such amounts shall not be less than ten (10) kilograms for the
             Phase II trials and one hundred (100) kilograms for the Phase III
             trials, provided that the conduct of such trials is approved by the
             United States Food and Drug Administration (the "FDA"). Provided
             that OPOCRIN continues to comply with its obligations under this
             Agreement, PARTEC agrees that it shall continue to purchase from
             OPOCRIN all the DS it shall require for the sale and distribution
             of Sulodexide subsequent to the approval of such sale by the FDA,
             and shall recommend to its sublicensees, if any, that they should
             purchase their DS needs from OPOCRIN as well.

         2.  OPOCRIN states that its production of DS is made according to its
             own Drug Master File ("D.M.F.") (which was supplied by ALFA to
             PARTEC under a separate agreement) which shall comply with
             acceptable manufacturing procedures. OPOCRIN agrees to comply in
             the future with the regulations and guidelines promulgated from
             time to time by the FDA and other regulatory authorities and
             current Good Manufacturing Practices ("cGMP"). The above mentioned
             D.M.F. contains an International Validation to exclude the presence
             of conventional viruses in the final product.

[CONFIDENTIAL TREATMENT HAS BEEN REQUESTED FOR INFORMATION REDACTED FROM THIS
PAGE.]

         3.  PARTEC's purchase of DS from OPOCRIN shall not confer on PARTEC or
             its licensees, affiliates and/or partners, any licensee, express or
             implied, of OPOCRIN's proprietary, confidential information and
             know-how.

         4.  OPOCRIN requires a minimum lead time from the placement of an order
             up to the date of delivery of forty five (45) Italian business
             days. Provided that PARTEC has not been declared in breach of this
             Agreement by OPOCRIN, OPOCRIN may not refuse a production order
             from PARTEC made pursuant to this Agreement.

         5.  OPOCRIN shall give written notice of at least sixty (60) days to
             PARTEC in the event that it takes any operational or strategic
             decision that could affect, in any way, the timely and appropriate
             fulfillment of OPOCRIN's obligations set forth in this Agreement
             and shall take all necessary steps to prevent such decision having
             such effect.

         6.  OPOCRIN agrees that in the event that (a) it becomes unable to meet
             the needs of PARTEC for the production of DS; or (b) PARTEC has
             sublicensed some or all of its rights to produce and sell
             Sulodexide to a third party that, in spite of PARTEC's
             recommendation to purchase its DS needs from OPOCRIN, chooses to
             move the manufacture of DS from OPOCRIN to another manufacturer,
             OPOCRIN shall transfer, without cost to PARTEC beyond the amounts
             set forth in paragraph 10, below, all information produced by it in
             connection with the fulfillment of its obligations under this
             Agreement, but not proprietary to OPOCRIN, to PARTEC for
             transmission to such other manufacturer. In the event that
             information proprietary to OPOCRIN is required by the other
             manufacturer to produce DS according to the specifications
             required, OPOCRIN shall be entitled to a reasonable license fee for
             such information upon reasonable terms and conditions to be
             negotiated between OPOCRIN and the relevant parties. Absent the
             successful conclusion of such a license agreement to OPOCRIN's
             proprietary information, OPOCRIN shall have no obligation to
             release such proprietary information to PARTEC or any third party.

         7.  OPOCRIN shall supply all the data in its possession required by
             PARTEC in connection with its Initial New Drug application with the
             FDA within twenty one (21) days of PARTEC's request for such data.
             In addition, OPOCRIN, at the appropriate time, shall generate, in
             return for the *** payment set forth in paragraph 10, below, all
             reasonable data necessary to support an approvable D.M.F. and shall
             provide PARTEC with a letter of authorization referencing the
             "closed section" of the D.M.F. for the purposes of complying with
             FDA requirements ("Letter of Authorization").

         8.  As soon as practicable after receiving FDA approval for an
             appropriate IND, and in each September thereafter, the PARTIES
             shall meet to discuss forecasts of PARTEC's anticipated future
             needs. Should the parties agree that PARTEC's anticipated future
             needs exceed OPOCRIN's manufacturing capacity, OPOCRIN shall submit
             a plan within three (3) months of the data such under-capacity
             becomes known to the parties whereby it shall increase such
             capacity.

PRICE, SHIPPING AND TERMS OF DELIVERY

         9.  The per kilogram price for the DS being purchased in connection
             with the Phase II and III clinical trials shall be calculated by
             multiplying the per kilogram United States bulk price of sodium
             heparin at the time each order is placed by PARTEC by a factor of
             ***. The price quoted by OPOCRIN on each order shall be the total
             price invoiced to and paid by PARTEC and shall subsume any and all
             costs incurred by OPOCRIN in the performance and production of such
             order. The parties shall negotiate in good faith the yearly price
             for DS once, and if, the FDA grants its approval for the commercial
             marketing of DS.

         10. Within ten (10) days of the date of the execution of this
             Agreement, PARTEC shall pay to OPOCRIN the amount of ***. This
             payment represents (a) a *** non-refundable payment in
             consideration of the set-up work that OPOCRIN is required to do at
             the proper time to comply with its obligations under this
<PAGE>


[CONFIDENTIAL TREATMENT HAS BEEN REQUESTED FOR INFORMATION REDACTED FROM THIS
PAGE.]
             Agreement, including, but not limited to, the preparation of the
             D.M.F., the Letter of Authorization and all supporting materials;
             and (b) a *** non-refundable advance against payment for the DS to
             be purchased in connection with the Phase II clinical trials.
             Within ten (10) days of the successful completion of the Phase II
             trials, PARTEC shall pay to OPOCRIN the amount of *** as an advance
             against payment for the DS to be purchased in connection with the
             Phase III clinical trials. In the event that such Phase III trials
             are not held, OPOCRIN shall refund PARTEC this *** prepayment.

         11. OPOCRIN sells DS, C.L.F. arrival at a location of PARTEC's
             choosing. All orders of DS shall be shipped by OPOCRIN in a manner
             that accords with cGMP quality and accreditation requirements.
             OPOCRIN shall provide all reasonable documentation necessary to
             allow the release of the order from any reasonable customs
             restrictions to either PARTEC or a third party designated by
             PARTEC, but shall not be responsible for the final clearing of the
             order from customs. PARTEC shall be responsible for paying all
             appropriate customs duties and charges.

         12. PARTEC shall pay for each order of DS as follows: Fifty percent
             (50%) of the purchase price by Swift telex transfer to OPOCRIN not
             later than 30 (thirty) days from the date of invoice; and fifty
             percent (50%) of the purchase price by Swift telex transfer to
             OPOCRIN not later than fifty (50) days from the date of the AWB
             accompanying the order.

WARRANTY AND QUALITY CONTROL

         13. OPOCRIN warrants:

             a) That DS shall be of the kind and quality described in the
                product specifications of the relative D.M.F.,

             b) That the certificate of analysis which will accompany DS is
                correct and has been produced using accepted procedures and
                standards and by reputable workers, and

             c) That it shall update the D.M.F. as required by relevant
                governmental requirements of the FDA, with a copy to PARTEC.

         14. OPOCRIN agrees that it shall perform a thorough quality control
             check on each batch of DS manufactured pursuant to an order
             submitted by PARTEC and that such check shall include, but not
             necessarily be limited to, characterization and statistical
             analysis of potency.

         15. At least six (6) weeks Prior to the scheduled dispatch of each
             batch of DS, OPOCRIN shall send a sample of the batch to PARTEC, or
             to a third party designated in writing by PARTEC. PARTEC shall have
             the sample analyzed according to the technique set out in the
             D.M.F. and shall communicate the results of the analysis to OPOCRIN
             within four (4) weeks of receipt of the sample. If, after
             conducting the quality testing set forth in this paragraph, a
             sample is determined to have failed such quality testing, OPOCRIN
             shall replace, within twenty (20) Italian business days of receipt
             of written notification by PARTEC, the defective sample at its own
             expense and pay all freight with respect to such replacement.
             PARTEC assumes sole responsibility for determining whether the DS
             is suitable for the use contemplated by PARTEC.

         16. PARTEC, or a third party chosen by it, shall analyze each batch of
             DS upon receipt and shall inform OPOCRIN within fourteen (14) days
             of PARTEC's receipt of the batch of any discrepancy between the
             analysis of the sample provided and approved under paragraph 14,
             above, and the analysis of the batch of DS. If, after conducting
             the analysis set forth in this paragraph, a batch is determined to
             be different than the sample approved under paragraph 14, above,
             OPOCRIN shall replace, within 3 (three) weeks of receipt of written
             notification by PARTEC, the defective batch at its own expense with
             a sample of a new batch in the manner set forth in paragraph 15,
             above, and pay all freight and duty with respect to such
             replacement,
<PAGE>

CONFIDENTIAL

             provided, however, PARTEC has stored the batch under proper
             conditions from the date it received such batch. In the event of
             any disagreement over the analysis conducted pursuant to this
             paragraph, the PARTIES shall use all reasonable means to reach
             agreement.

         17. In the event that the sample or the batch of DS manufactured by
             OPOCRIN to replace the defective batch should itself fail to pass
             the agreed upon quality control standards set forth in the D.M.F.
             and this Agreement, OPOCRIN shall pay any definitively
             ascertainable consequential damages incurred by PARTEC as a result
             of the delay in production of Sulodexide tablets engendered by a
             delay caused by such failure, including, but not limited to, any
             costs associated with the cancellation of tablet manufacturing
             previously scheduled in reliance upon OPOCRIN's timely production
             and delivery of conforming DS, provided that in no event shall such
             damages, even if proven, exceed one-third (1/3) of the purchase
             price of such batch.

         18. Any dispute regarding the quality of a batch delivered pursuant to
             this Agreement that cannot be settled amicably within thirty (30)
             days after it arose shall be referred to an independent testing
             organization that meets appropriate Good Laboratory Practices or to
             a consultant of recognized repute within the European
             Pharmaceutical Industry mutually agreed upon by the parties. If the
             parties cannot agree on the appointment of such organization or
             consultant within forty five (45) days after the dispute arose,
             either party may request the chairman of the International Chamber
             of Commerce to appoint an organization or consultant. The
             determination of the organization or consultant so chosen or
             appointed shall be final and binding on the parties. Any fees and
             expenses of the organization or consultant shall be borne by the
             party against which the determination is made.

RECORDS AND CONFIDENTIALITY

         19. OPOCRIN shall maintain the appropriate records in connection with
             the production of DS for PARTEC pursuant to this Agreement. At
             least once in each six (6) month period (beginning with the
             execution of this Agreement), OPOCRIN shall provide PARTEC with a
             complete set of such records in electronic and typed form. All
             records required to be maintained by this Agreement shall be
             maintained in the English language.

         20. The parties recognize that in the course of fulfilling their
             respective obligations pursuant to this Agreement, they will have
             occasion to disclose to each other confidential and proprietary
             information. Accordingly, they agree to execute a non-disclosure
             agreement substantially in the form as annexed to this Agreement as
             Attachment A.

LIABILITY AND INDEMNIFICATION

         21. Other than as set forth in paragraph 17 above, OPOCRIN shall only
             be liable for any injury, monetary or otherwise, suffered by PARTEC
             or any third party in connection with the Product or its use, if
             and only to the extent such injury was caused by the Product at
             issue not being manufactured in conformance with the requirements
             of the D.M.F. and the other provisions of this Agreement.

         22. PARTEC agrees to indemnify, hold harmless and defend OPOCRIN, its
             trustees, officers, employees, and agents from and against any and
             all claims, suits, losses, damages, costs; fees, expenses
             (including reasonable attorney's fees), and other liabilities
             asserted by third parties, both government and non-government,
             resulting from or arising out of the manufacture and supply of the
             Product carried out pursuant to this Agreement; provided, however,
             that PARTEC shall not be liable for (a) negligence, international
             wrongdoing, or failure to follow the provisions of this Agreement,
             by OPOCRIN, its trustees, officers, employees and agents and (b)
             any and all claims for damages to OPOCRIN property or for bodily
             injury, death or property damage to employees of OPOCRIN arising
             out of the performance of this Agreement, except for the negligent
             or international acts solely of the PARTEC with respect to both (a)
             and (b) above, Without limiting the foregoing, except for the
             negligence or willful misconduct of OPOCRIN, PARTEC agrees to
             indemnify and defend OPOCRIN from all

             liabilities, demands, damages, expenses and losses (including
             reasonable attorney fees and expenses of litigation) arising out of
             the use by PARTEC, or any party acting on behalf of or under
             authorization from PARTEC, of the Product; provided, however, that
             the Product has been manufactured in accordance with the provisions
             of this Agreement. This paragraph shall survive termination of this
             Agreement.

         23. OPOCRIN agrees to indemnify, hold harmless and defend the PARTEC,
             its directors, officers, employees, and agents from and against any
             and all claims, suits, losses, damage, costs, fees, expenses
             (including reasonable attorney's fees), and other liabilities
             asserted by third parties, both government and non-government,
             resulting from or arising out of the manufacture and supply of the
             Product carried out pursuant to this Agreement as a result of the
             negligence, intentional wrongdoing or failure to follow the
             provisions of this Agreement, of OPOCRIN, its trustees, officers,
             employees and agents and any and all claims for bodily injury,
             death or property damage to employees of OPOCRIN or to any third
             party acting on behalf of or under the authorization of OPOCRIN
             arising out of the performance of this Agreement; provided,
             however, that OPOCRIN shall not be liable for the negligent or

             Agreement shall remain in force for a period for ten (10) years
             from the date of its execution.

         25. Notwithstanding the provisions of paragraph 24, above, this
             Agreement may be terminated; (a) by either party upon one hundred
             and eighty (180) days advance written notice, provided that should

MISCELLANEOUS PROVISIONS

         27. Independent Contractors: The relationship between OPOCRIN and

             representatives, or employees shall be considered employees of the
             other. The parties shall each conduct their respective businesses
             on their own initiative and responsibility and shall have no
             authority to incur any obligations on behalf of the other. Except
             as otherwise set forth in this Agreement, each party shall pay all

                                 ATTACHMENT A

                                  PARTEC LTD
                       Bio-Medical Venture & Management

                           CONFIDENTIALITY AGREEMENT

This Agreement dated 16 April 1999 shall serve to set forth the terms and
conditions under which Partec Ltd. ("Partec") shall disclose to Opocrin, S.P.A.
("Opocrin") (or the "Receiving Party" or the "Disclosing Party", as appropriate)
proprietary and confidential information to each other, including, but not
limited to any and all information, know-how and data, technical or
non-technical, and product samples and specifications relating to the
manufacture of Sulodexide (the "Information").

1.  The Receiving Party agrees not to divulge the Information which the
Disclosing Party discloses to it and which is marked as "Confidential" (the
"Confidential Information") to any third party or parties, or use said
Confidential Information for any purposes other than those purposes set forth in
the Manufacturing Agreement executed between the parties on 16 April 1999. The
Receiving Party further agrees to limit disclosure only to those of its
officers, employees, agents, affiliates and consultants as the Receiving Party
considers necessary. The Receiving Party shall take all reasonable steps to
prevent the disclosure of the Confidential Information as provided herein. This
obligation shall be binding upon the Receiving Party and shall continue for a
period of five (5) years from each date such Confidential Information is
disclosed to the Receiving Party.

2.  Nothing in the foregoing shall be construed to prevent the Receiving Party
from disclosing or using any Information or from using Confidential Information
which:

(a) was in the Receiving Party's possession or control prior to the date of
disclosure;

(b) was in the public domain or enters into the public domain through no
improper act on the Receiving Party's part or on the part of any of the
Receiving Party's employees;

(c) is approved for public release by written authorization by the Disclosing
Party;

(d) is developed independent of the information derived from the Confidential
Information;

(e) is required to be disclosed by legal, administrative or judicial order; or

(f) is rightfully given to the Receiving Party from sources independent of the
Disclosing Party, its employees or agents.

3.  Oral information which the Disclosing Party wishes to be kept confidential
must be reduced to writing and provided to the Receiving Party within thirty
(30) days of the initial disclosure to the Receiving Party by the Disclosing
Party and conspicuously marked "Confidential."

4.  It is understood and agreed that any and all propriety rights, including,
but not limited to, patent rights, trademarks and proprietary rights in and to
the Confidential Information disclosed to the Receiving Party shall be and
remain in the possession of the Disclosing party and the Receiving party shall
have no right, title or interest in or to any of the Confidential Information.
In addition, nothing in this Agreement shall be construed as establishing any
joint venture or other business relationship, as granting to the Receiving Party
any license or right under any patent rights or as representing any commitment
by either party to enter into any license or other agreement by implication or
otherwise.

5.  This Agreement constitutes the entire agreement of the parties pertaining to
the subject matter hereof, and all prior or contemporaneous understandings or
agreements, whether written or oral, between the parties with respect to such
subject matter are hereby superseded in their entirety. The parties have made no
agreements, representations or warranties relating to the subject matter of this
Agreement which are not set forth herein and no agreement, understanding or
promise subsequent to the date hereof relating to the subject matter of this
Agreement, the Confidential Information or otherwise between or by one of the
parties hereto shall be binding upon either party unless in writing and executed
by both The Disclosing Party and the Receiving Party and neither party shall be
reasonable in relying on oral statements made by the other which are not
contained in a written agreement.

6.  This Agreement may not be modified, amended or waived in any manner except
by an instrument in writing signed by each of the parties hereto. The waiver by
either party of compliance with any provision of this Agreement by the other
party shall not operate or be construed as a waiver of such party of a provision
of this Agreement. Neither party may assign its rights or obligations hereunder.

7.  This Agreement shall be governed by and construed in accordance with the
laws of the United Kingdom without regard to the conflicts of the law principles
thereof.

8.  In addition, each party warrants to the other party that the person signing
this Agreement on behalf of the such party is fully authorized to bind the such
party to the obligations set forth in this Agreement.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed
by their respective duly authorized representatives as of the day and year
written above.
