      Corporation without prior notice and without further obligations to the Employee
      during the first three months of the date hereof;




8.1.2.  by
      the
      Corporation without prior notice and without further obligations to the Employee
      for reasons of Just Cause;




8.1.3.  by
      the
      Corporation for any reason other than Just Cause, on twelve months’ prior
      written notice to the Employee, provided that if the Employee is entitled under
      the ESA to a longer period of notice than that prescribed above, the notice
      to
      be given by the Corporation under this section 8.1.2 shall be
      that minimum period of notice which is required under the ESA and no more;
      or




8.1.4.  by
      the
      Employee on one month’s prior written notice to the Corporation.




The
      Employee’s employment shall be automatically terminated, without further
      obligation to the Employee, in the event of her death.




8.2.**Effective
      Date****.**The
      effective date on which the Employee’s employment shall be terminated shall
      be:




8.2.1.  in
      the
      case of termination under section 8.1.1 or
      section 8.1.2 ,
      the day
      the Employee is deemed, under section 17 ,
      to have
      received notice from the Corporation of such termination;

      the
      case of termination under section 8.1.3 or

      Work Notice”), to require that the Employee cease to perform her duties and
      responsibilities and cease attending the Corporation’s premises immediately upon
      the giving of the Stop Work Notice. If a Stop Work Notice is given, the
      Corporation shall continue to pay the Employee to the end of the Employment

      coverage), less any amounts payable to the Employee in lieu of notice where
      a
      Stop Work Notice has been given pursuant to section 8  and

      any time without notice or further obligations to the Employee under this
      Agreement for reasons of Just Cause. For greater certainty, following a Change

      the Employee if the Employee is, at the relevant time, a director of the
      Corporation) at a meeting of the board called and held for the purpose (after
      reasonable notice to the Employee), finding that, in the good faith opinion
      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.

      of Employment Without Just Cause or for Good Reason**.
      If at
      any time within 24 months following a Change of Control, the Employee’s
      employment is terminated (i) by the Corporation other than for Just Cause
      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 the aggregate
      of (i) twelve (12) months of the Employee’s Basic Salary and (ii) the average
      amount of the per annum bonus remuneration paid to the Employee during each
      full
      Year of Employment during the Employment Period, less any required statutory
      deductions and withholdings;




10.2.2.  the
      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 her 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 or result in a Change of Control;
      (ii) the Employee terminates her 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
      Corporation or any shareholder of the Corporation, the consummation of which
      would constitute or result in 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
      apply in the event of the termination of the employment of the Employee: (i)
      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
      section 1 7 hereof,
      give the other notice thereof.

            **No
                Obligation to Mitigate**

      Employee shall not be required to mitigate
      any damages or losses arising from any termination of this Agreement by seeking
      other employment or otherwise, nor (except as specifically provided herein)
      shall the amount of any payment provided for in this Agreement be reduced by
      any
      compensation earned by the Employee as a result of employment by another
      employer after termination or otherwise .

      principal, agent, director or shareholder:




(i)
            be
                engaged in any undertaking;




(ii)
            have
                any financial or other interest (including an interest by way of
                royalty
                or other compensation arrangements) in, or in respect of, the business
                of
                any Person which carries on a business;
                or

                the use

      involves the development, manufacturing, sales and/or distribution of products,
      equipment, services and/or technology relating to the apheresis treatment of
      ophthalmic diseases or which is otherwise the same as, or substantially similar
      to, or which competes with or would compete with, the business carried on by
      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
      with or would compete with, the business of the Corporation or any of its
      Subsidiaries.

      may
      be.

            **No
                Solicitation of
                Employees**




The
      Employee shall not, either during the Employment Period or the Restricted

      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:




15.1.  the
      Confidential Information is available to the public or in the public domain
      at
      the time of such disclosure or use, without breach of this Agreement;

The
      Employee acknowledges that a breach or threatened breach by the Employee of
      the
      provisions of any of sections 12 to 15 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.
