acknowledge and agree that after the Closing: (i) the Shares may not be sold,
assigned or otherwise transferred unless a registration statement is in effect
with respect to such resale or an exemption for such resale under applicable

evidenced by an opinion of counsel delivered and addressed to KENSEY NASH,
which opinion must be reasonably acceptable to KENSEY NASH), (ii) KENSEY NASH
is under no obligation to prepare or file a registration statement for the
Shares at any time, (iii) the certificates evidencing the Shares will bear the
following legends in substantially the following form:

      "The shares represented by this certificate have not been registered
      under the Securities Act of 1933, as amended (the "Act"), or under any
      state securities laws, and thus may not be sold, assigned or otherwise
      transferred unless so registered or unless an exemption from registration
      is available, which exemption shall be established by an opinion of
      counsel, reasonably satisfactory in form and substance to the issuer and
      delivered and addressed to the issuer by counsel for the registered owner
      of the shares evidenced hereby" and

      "Until 40 days or such longer period that may be required under
      applicable law or regulation under the Act, the shares represented by
      this certificate may not be sold to a U.S. person or into the United
      States."

; and (iv) KENSEY NASH will issue instructions to its transfer agent to
the effect that subsequent transfer of the Shares may not be effected unless
the transfer agent has received evidence reasonably satisfactory to it that
such transfer may be made without violating applicable securities laws.

      (b) VAN DE MOER, RIENKS, INNOVASC and MEDIFIX severally, but not jointly,
covenant and agree, with respect to the number of Shares and periods of time
listed on Schedule 1 hereto, not to (i) offer, pledge, sell, contract to sell,
sell any option or contract to purchase or purchase any option or contract to
sell, grant any option, right or warrant to purchase, or otherwise transfer or
dispose of, directly or indirectly, any of the Shares during any period of time
specified, in excess of the number of Shares set forth on Schedule 1 for such
period; provided that if the permitted number of Shares is not sold or
otherwise disposed of during any such time period the Shares not sold or
otherwise disposed of shall be carried forward 


                                      12
   13

and added to the number of Shares which may be sold or otherwise disposed of    
during the next succeeding time period, and this procedure shall be repeated in
subsequent time periods; or (ii) enter into any swap or other arrangements that
transfer all or a portion of the economic consequences associated with the
ownership of the Shares (regardless of whether any of the transactions
described in clause (i) or (ii) is to be settled by the delivery of Common
Stock or other securities of KENSEY NASH, in cash or otherwise), without the
prior written consent of KENSEY NASH. VAN DE MOER, RIENKS, INNOVASC and MEDIFIX
jointly and severally authorize KENSEY NASH to cause the transfer agent to
decline to transfer and/or to note stop transfer restrictions on the transfer
books and records of KENSEY NASH with respect to any of the Shares for which
INNOVASC and MEDIFIX is the record holder and, in the case of any such Shares
for which INNOVASC and MEDIFIX is the beneficial but not the record holder,
agree to cause the record holder to cause the transfer agent to decline to
transfer and/or to note stop transfer restrictions on such books and records
with respect to such Shares.

12.  Non-Competition.

     (a) VAN DE MOER, RIENKS, INNOVASC and MEDIFIX severally, but not
jointly, covenant and agree that none of them nor any of their affiliates,
successors or assigns will, for a period of three (3) years from the Closing
Date, without KENSEY NASH's prior written consent, by itself or in partnership
or conjunction with, or as a manager, consultant or agent of, any other person,
firm, corporation or other entity, either directly or indirectly, undertake or
carry on or be engaged or have any financial or other interest in, or in any
other manner advise or assist, any person, firm, corporation or other entity
engaged or interested in, any business (any such business is referred to herein
as a "Competitive Business") involving the Patent Property or other vascular
closure devices on a worldwide basis.  The ownership of an equity interest of
five percent (5%) or less of any publicly-traded entity shall not be deemed a
violation of this covenant.

     (b) VAN DE MOER, RIENKS, INNOVASC and MEDIFIX jointly and severally agree
and warrant that the covenants contained in this Section are reasonable, that
valid consideration has been received therefor and that the agreements set
forth in this Section are the result of arm's-length negotiation between the
parties hereto.

     (c) VAN DE MOER, RIENKS, INNOVASC and MEDIFIX jointly and severally
acknowledge that in the event of any violation of the covenants contained in
this Section 12 or Section 10, KENSEY NASH's damages will be difficult to
ascertain and KENSEY NASH's remedy at law may be inadequate.  Accordingly, VAN
DE MOER and RIENKS severally, but not jointly, agree that in the event of any
violation, (i) they shall forfeit the Cash Payments, (ii) they shall forfeit to
KENSEY NASH any and all consideration or profit (in whatever form) received or
to be received in connection with such violation  and (iii) KENSEY NASH shall
be 


                                      13
   14

entitled to specific performance of such covenants and to an injunction to
prevent any continuing violation thereof without the necessity of posting a
bond.

     (d) If any of the provisions of or covenants contained in this Section is
hereafter construed to be invalid or unenforceable in any jurisdiction, the
same shall not affect the remainder of the provisions or the enforceability
thereof in any other jurisdiction, which shall be given full effect, without
regard to the invalidity or unenforceability in such other jurisdiction.  If
any of the provisions of or covenants contained in this Section is held to be
unenforceable in any jurisdiction because of the duration or geographical scope
thereof, the parties agree that the court making such determination shall have
the power to reduce the duration or geographical scope of such provision or
covenant and, in its reduced form, said provision or covenant shall be
enforceable; provided, however, that the determination of such court shall not
affect the enforceability of this Section in any other jurisdiction.

     13. Default.  In the event KENSEY NASH fails to make, when due, any of the
Cash Payments referred to in Section 3 of this Agreement within thirty (30)
days after the date such Cash Payment becomes due and payable thereunder and is

days, KENSEY NASH hereby agrees to transfer all of its right, title and
interest in and to the Patent Property to INNOVASC and MEDIFIX by means of an
assignment agreement, substantially in the form of the Assignment Agreement
attached hereto as Exhibit E.

     14. Expenses. The reasonable legal fees and expenses of INNOVASC and

in connection with the negotiation and preparation of this Agreement and the
