                             DISTRIBUTION AGREEMENT

         2.01 Closing Conditions.

             In addition to and without limitation of the conditions set forth
in Section 8.01 of the Original Agreement, Buyer's obligation to consummate the
transactions to be performed by it in connection with the Closing and the
effectiveness of this Amendment, in each case, are subject to Seller and Parent
having delivered to Buyer the exclusive manufacture, supply and distribution
agreement, substantially in the form attached as Appendix A to this Amendment
(the "Distribution Agreement"), duly executed by Seller and Parent.

         2.02 Purchased Goods; Product Inventory Conversion; Transfer Price
Reduction.

                 (a) All Product Inventory listed under the headings "Finished
         Goods Subject to Completion of Requalification," "WIP Catheters -
         Decathlon and Alta" and "Other Raw Materials" in the Closing Inventory
         Statement will be held by Seller for the benefit of Buyer, and
         ownership thereof will at all times remain in Buyer (hereinafter, the
         "Purchased Goods"). The Purchased Goods will be deemed to be included
         as "Acquired Assets" for all purposes of the Agreement. Seller agrees
         to pay Buyer for any Purchased Goods that are lost, damaged, destroyed
         or incorporated in a failed batch,

                                       9


         provided that Seller shall not pay for any Purchased Goods used in
         manufacture and incorporated or otherwise consumed in the production of
         Product that meets applicable Product Specifications. Seller will store
         or have stored all Purchased Goods at no cost to Buyer at Seller's or
         its manufacturers' facilities, as applicable. Seller shall, and shall
         cause its manufacturers to, comply with all storage and handling
         requirements for Purchased Goods. The Purchased Goods shall remain in
         their original packaging until further processing is required. The
         Purchased Goods shall only be used to manufacture Distributed Product
         (as defined in the Distribution Agreement) pursuant to the Distribution
         Agreement. Seller will not do or permit to be done anything that might
         prejudice Buyer's ownership or other rights in and to the Purchased
         Goods. Seller will maintain a system under which the Purchased Goods
         are clearly identified as being owned by Buyer (including, as
         appropriate, the use of tags, signs, stickers or plates to evidence
         Buyer's ownership) and the Purchased Goods shall be kept separate and
         distinct from Seller's or its manufacturers' property and any other
         property in the possession or under the control of Seller or its
         manufacturers, as applicable. Seller acknowledges that none of the
         Distribution Agreement, the Agreement and Seller's, any Seller
         Affiliate's or manufacturer's possession of the Purchased Goods will
         constitute a "bailment," "consignment" or "security agreement," or
         create a "security interest" within the meaning of the Uniform
         Commercial Code. Seller will keep the Purchased Goods free and clear of
         all Encumbrances and will not assert against the Purchased Goods any
         statutory or possessory liens (including processors' liens), all of
         which Seller hereby waives. Seller authorizes Buyer to file such
         financing statements and other documents and instruments as Buyer
         reasonably deems necessary or advisable to protect Buyer's ownership or
         other rights in the Purchased Goods purchased and paid for by Buyer,
         provided that such filings do not name as collateral any product,
         material, equipment or facility owned or leased by Parent or Seller.

                 (b) Promptly following the Closing, Seller shall use all
         commercially reasonable efforts to complete the requalification of the
         finished goods listed under the heading "Finished Goods Subject to
         Completion of Requalification" in the Closing Inventory Statement for
         return to commercial inventory (including labeling such finished goods)
         and, once so requalified such finished goods shall be delivered, and
         shall be deemed to be supplied to Buyer, pursuant to and in accordance
         with the terms and conditions of the Distribution Agreement; provided
         that Buyer shall not be required to pay any consideration to Seller
         with regard thereto.

                 (c) Promptly following the Closing, Seller shall use all
         commercially reasonable efforts to process and convert into finished
         goods all Product Inventory listed under the heading "WIP Catheters -
         Decathlon and Alta" (including any sub-heading thereunder) in the
         Closing Inventory Statement and, once so processed and converted, such
         finished goods shall be delivered, and shall be deemed to be supplied
         to Buyer, pursuant to and in accordance with the terms and conditions
         of the Distribution Agreement. If and to the extent that by December
         18, 2009 ("WIP Conversion Deadline"), any WIP catheter listed under the
         sub-heading "WIP Catheters for Conversion Alta and Decathlon" in the
         Closing Inventory Statement shall not have been so processed and
         converted into a finished Product and shall not be available and ready
         to ship to Buyer (each, an "Unconverted WIP Catheter"), Buyer, at its
         option, shall receive a credit in an aggregate amount (the "WIP
         Credit") equal to three (3) times the cost value (as listed in the
         Closing Inventory Statement) for each Unconverted WIP Catheter as of
         the WIP Conversion Deadline, which Buyer may apply, at its sole
         discretion, towards the Milestone Payment, the Contingent Deferred
         Payment or Buyer's purchase of Distributed Product (as defined in the
         Distribution Agreement) under the Distribution Agreement.
         Notwithstanding anything herein or in the Distribution Agreement to the
         contrary, with regard to any WIP catheters listed under the sub-heading
         "WIP Catheters for Conversion Alta and Decathlon" in the Closing
         Inventory Statement, Buyer shall not be required to pay any
         consideration to Seller with regard thereto, whether for processing,
         conversion or delivery.

                 (d) On the WIP Conversion Deadline, Seller and Parent shall
         deliver a certificate to Buyer, dated as of the WIP Conversion Deadline
         and executed by the Chief Financial

                                       10


         Officer or Chief Executive Officer of each of Seller and Parent, which
         shall identify the aggregate number of Unconverted WIP Catheters as of
         the WIP Conversion Deadline, if any, and the amount of the WIP Credit,
         if any. Buyer shall have the right to (i) conduct an independent
         physical inspection and count of the Purchased Goods (including the WIP
         catheters and Unconverted WIP Catheters) and (ii) dispute Seller's and
         Parent's count of the Unconverted WIP Catheters and calculation of the
         WIP Credit set forth in such certificate. If there is any dispute, the
         Parties shall promptly meet and make a good faith effort to resolve any
         disagreements between them and, if not resolved through such efforts,
         such dispute shall be resolved in accordance with the terms of the
         Agreement.

                 (e) The transfer price paid by Buyer under the Distribution
         Agreement for Distributed Product (as defined in the Distribution
         Agreement) that incorporates any item of Product Inventory listed under
         the heading "Other Raw Materials" in the Closing Inventory Statement
         shall be reduced by the standard cost value (as listed in the Closing
         Inventory Statement) of such Product Inventory, on a dollar-for-dollar
         basis, to reflect the fact that such Product Inventory is a Purchased
         Good and has been purchased and paid for by Buyer under the Agreement.
         Seller may use items of Product Inventory listed under the heading
         "Other Raw Materials" in the Closing Inventory Statement as necessary
         in the process of converting the WIP catheters into finished goods
         hereunder.

             In the event of a conflict between the terms and conditions
contained in the Original Agreement, as amended by this Amendment, and those
contained in the Distribution Agreement, the terms and conditions of the
Distribution Agreement shall prevail.
