      written notice to the Employee, provided that if the Employee is entitled under

      of
      the Board, the Employee’s conduct constituted Just Cause and specifying the
      particulars thereof. The date on which the copy of such resolution is given
      to
      the Employee shall be the effective date of any termination pursuant to this
      section10.1.

      any time within 24 months following a Change of Control, the Employee’s

      or (ii) by the Employee in response to a Good Reason, the following
      provisions shall apply:




10.2.1.  the
      Employee shall be entitled to receive, and the Corporation shall pay to the
      Employee immediately following termination, a cash amount equal to 18 months
      of
      the Basic Salary and 150% of the average per annum bonus remuneration paid
      to
      the Employee during the Employment Period, less any required statutory

      Employee shall be entitled to receive, and the Corporation shall pay to the
      Employee, immediately following termination, a cash amount equal to 2.5 percent
      of his annual Basic Salary in lieu of continued benefit coverage;
      and




10.2.3.  if
      at the
      date of termination of the Employee’s employment, the Employee holds options for
      the purchase of shares under a share option plan, all options so held shall,
      notwithstanding the terms of the Corporation’s share option plan,
      (i) immediately vest to the extent they have not already vested at such
      date; and (ii) (A) for a period of two years following the Employee’s
      date of termination continue to be held on the same terms and conditions as
      if
      the Employee continued to be employed by the Corporation or (B) if the
      Employee so elects in writing within 90 days after the date of termination,
      be
      purchased by the Corporation at a cash purchase price equal to the amount by
      which the aggregate “fair market value” of the shares subject to such options
      exceeds the aggregate option price for such shares, provided that for this
      purpose, “fair market value” means the higher of (i) the weighted average of the
      closing prices for the shares of the same class of the Corporation on the
      principal securities exchange (in terms of volume of trading) on which such
      shares are listed at the time of termination for each of the last 10 days prior
      to such time on which such shares traded on such securities exchange, and (ii)
      if the Change of Control involved the purchase and sale of such shares, the
      average value of the cash consideration paid to the shareholders of the
      Corporation in connection with the transactions resulting in the Change of
      Control.




For
      purposes of this Agreement, the Employee’s employment shall be deemed to have
      been terminated following a Change of Control by the Corporation without Just
      Cause or by the Employee with Good Reason, if: (i) the Employee’s employment is
      terminated by the Corporation without Just Cause prior to a Change of Control
      and such termination was at the request or direction of a Person who has entered
      into an agreement with the Corporation or any shareholder of the Corporation,
      the consummation of which would constitute a Change of Control; (ii) the
      Employee terminates his employment with Good Reason prior to a Change of Control
      and the circumstance or event which constitutes Good Reason occurs at the
      request or direction of a Person who has entered into an agreement with the

      would constitute a Change of Control; or (iii) the Employee’s employment is
      terminated by the Corporation without Just Cause prior to a Change of Control
      and the Employee reasonably demonstrates that such termination is otherwise
      in
      connection with, or in anticipation of, a Change of Control which actually
      occurs.

For
      greater certainty, this section 10.2  does
      not

      as
      a result of death, Disability or Retirement, (ii) by the Corporation for Just
      Cause or (iii) by the Employee without Good Reason. If the Employee or the
      Corporation intends to terminate the Employee’s employment as contemplated in
      this section 10 ,
      the
      party having such intention shall, in accordance with the provisions of

which
      involves the development, manufacturing, sales and/or distribution of products,
      equipment, services and/or technology relating to the apheresis treatment of

      the
      Corporation or any of its Subsidiaries during the Employment Period or at the
      end thereof.




Notwithstanding
      the foregoing, nothing herein shall prevent the Employee from owning not more
      than 5% of the issued and outstanding shares of a corporation, the shares of
      which are listed on a recognized stock exchange or traded in the
      over-the-counter market in Canada or the United States, which carries on a
      business which is the same as, or substantially similar to, or which competes

      may
      be.

**14.**
            **No
                Solicitation of
                Employees**

      or attempt to induce or solicit, any such person to leave his/her
      employment.




**15.**
            **Confidentiality**




The
      Employee shall not, either during the Employment Period or at any time
      thereafter, directly or indirectly, use or disclose to any Person any
      Confidential Information, provided, however, that nothing in this section 15
      shall preclude the Employee from disclosing or using Confidential Information
      if:

The
      Employee acknowledges that a breach or threatened breach by the Employee of
      the
      provisions of any of sections 12 to15 inclusive will result in the
      Corporation and its shareholders suffering irreparable harm which is not capable
      of being calculated and which cannot be fully or adequately compensated by
      the
      recovery of damages alone. Accordingly, the Employee agrees that the Corporation
      shall be entitled to interim and permanent injunctive relief, specific
      performance and other equitable remedies, in addition to any other relief to
      which the Corporation may become entitled.
