    6.   Section 3.3 of the Agreement is hereby amended and restated in its
entirety to read as follows:

         3.3     Incremental Payments.  Purchaser shall make up to three
         additional payments (the "Incremental Payments") to the Company of Two
         Hundred Fifty Thousand Dollars ($250,000) each (or up to an additional
         aggregate amount of Seven Hundred Fifty Thousand Dollars ($750,000))
         in the event Gross Revenues from the sale of Cordguard I equal or
         exceed in a calendar year during the remaining validity of the Patent
         any of the following three benchmarks (with only one payment being due
         for achievement of each benchmark): (i) Gross Revenues exceed Ten
         Million Dollars ($10,000,000); (ii) Gross Revenues exceed Twenty
         Million Dollars ($20,000,000); or (iii) after achieving benchmark
         (ii), Gross Revenues exceed Twenty Million Dollars ($20,000,000) in a
         subsequent calendar year.  To illustrate Purchaser's obligation to
         make the Incremental Payments: (A) in the event Gross Revenues exceed
         Ten Million Dollars ($10,000,000) in one or more calendar years but
         never exceed Twenty Million Dollars ($20,000,000) in a calendar year,
         the Company shall only be entitled to the first Incremental Payment of
         Two Hundred Fifty Thousand Dollars ($250,000); (B) in the event Gross
         Revenues exceed Twenty Million Dollars ($20,000,000) in a calendar
         year without having previously exceeded Ten Million Dollars
         ($10,000,000), the Company shall be entitled to the first and second
         Incremental Payments of Two Hundred Fifty Thousand Dollars ($250,000)
         each for Cordguard I having achieved benchmarks (i) and (ii) in such
         calendar year; and (C) in the event Gross Revenues exceed Twenty
         Million Dollars ($20,000,000) in two calendar years, the Company shall
         be entitled to receive the third and final Two Hundred Fifty Thousand
         Dollars ($250,000) Incremental Payment with respect to such second
         calendar year.  Any Incremental Payment which become due shall be paid
         within thirty (30) days of the end of the year for which such payment
         is due.

    7.   Section 3.4.1 of the Agreement is hereby amended and restated in its
entirety to read as follows:

         3.4.1   Cordguard I.  Five percent (5%) of Gross Revenues relating to
         Cordguard I for the remaining validity of the Patent;
    8.   Except as expressly provided herein, the Agreement shall remain
unmodified and in full force and effect and, in the event of any inconsistency
between the terms of the Amendment and the Agreement, the terms of the Amendment
shall be controlling.

    9.   This Amendment may be executed in several counterparts, each of which
