                              LETTER OF ENGAGEMENT
                                 March 26, 2004


This letter constitutes a legal agreement (the "Agreement") between the joint
and equal partnership association of David Clark and Peter Wrage (the
"Partners"), and Liska Biometry Incorporated ("Liska" or "the Company"). Liska
wishes to engage the Partners as senior advisors and marketing consultants to
the executive of Liska, and the Partners hereby agree to become engaged in that
role, under the following terms and conditions.

1.   Services. Services provided by the Partners will be of an active nature as
     well as on an as-and-when  basis, and will be broad and diverse,
     incorporating but not limited to the following types of advisory services:

     a.   Provide assistance with the definition and strategic positioning of
          Liska and its products. Provide product advisory services regarding
          potential new or related  products and services for Liska based on
          their core technologies.

     b.   Help to develop a marketing strategy that will allow Liska to
          penetrate key market areas around the world.

     c.   Provide introductions to major government, international organizations
          and companies that are involved in security and biometrics.

     d.   Assist in negotiations of contract with such organizations.

2.   Further details of the scope and nature of services that may be provided by
     the Partners in this regard is provided in Annex "A" attached to this
     Agreement.

3.   This Agreement shall be for the initial term of April 1, 2004 through March
     31, 2005, and shall automatically renew under the same terms and conditions
     as of April 1 2005 unless either party posts written notice with the other
     party, in advance (30 days), that they wish to re-negotiate the terms of
     the Agreement upon renewal, or cancel the Agreement without renewal.

4.   Compensation. Compensation for services by the Partners shall not consist
     of hourly fees for work done, but rather be in the form of a  monthly
     retainer fee, plus bonuses for specific achievements of value to Liska.
     This compensation shall be as follows:

     a.   A  monthly retainer fee of $ 2,000 in US dollars (USD), plus all
          reasonable direct expenses incurred on behalf of Liska, payable to the
          Partners on the last business day of each month or part-month in which
          services are engaged. All expenses over $100 must be pre-approved by
          the Company in writing.

     b.   These retainer fees will be accrued but not paid by Liska, and be
          carried as an interest-free payable to the Partners, until such time
          as Liska achieves investment capital, amounting  to a minimum of
          $1,000,000 USD of equity in Liska. At this time all arrears fees due
          to the Partners shall be paid in full and all later fees shall be paid
          on the due date.

     c.   For revenue-based achievements (contracts) involving work by the
          Partners, a bonus of 4% of the contract value shall be payable to the
          Partners upon closure. (Any contingent value in the contract, such as
          renewal value of sales, shall have an equivalent bonus payable when
          such contingency is resolved and the additional fees accrue to Liska.)

     d.   For non-revenue achievements (e.g. recognition of the Liska biometric
          technology by ICAO nations for passport use), a fair and reasonable
          bonus shall be payable to the Partners as determined by the Company's
          board of directors.

     e.   Payment of bonuses in accordance with (c) or (d) above may be done in
          the form of shares with the mutual agreement of Liska and the
          Partners, in such quantities and under terms that are agreed between
          the parties in each case.

5.   Any payments of fees or bonuses made to the Partners shall be distributed
     in each case according to the wishes of the Partners, in a single payment
     with all relevant taxes, such as GST, as may be lawfully required but with
     no withholdings or deductions of any sort for any purpose.

6.   Both parties agree that this Agreement is not an agreement of employment,
     and the Partners hereby waive any rights of employment that might exist
     under any laws or practices of the USA or Canada in this regard.


7.   Other Considerations. Liska recognizes that the Partners are key
     individuals with long experience in application and biometric service
     industries, as well as executives with long experience in financing and
     management of high technology companies. Their experience will be very
     beneficial to Liska in achieving its objectives.

     a.   In consideration therefore of the Partners becoming engaged with Liska
          in this regard, and in further consideration of the non-compete
          clauses of this Agreement that exclude the Partners from taking any
          other assignments that may be of a competitive or conflicting  nature
          to Liska interests, Liska agrees that the Partners will be granted
          entitlement to 500,000 restricted shares of common stock of Liska upon
          signing of this Agreement.

     b.   These shares will be issued and delivered to the Partners in two
          tranches:
          (i)  100,000 shares upon signing of this agreement
          (ii) 400,000 shares will also be issued upon signing of this Agreement
               but be held back by Liska until the Partners have played a major
               role in delivering tangible benefits to Liska, as determined by
               the board, during the time period of this Agreement.

     c.   Liska and the Partners note that restricted common shares have no
          intrinsic or par value at this time, and that Liska cannot guarantee
          that this situation will change in the foreseeable future. The
          Partners acknowledge that they therefore have no claim on Liska for
          any valuation of shares received in this regard.

     d.   Further, the Partners understand and agree that these common shares of
          Liska are restricted from trading under Rule 144 of the Securities and
          Exchange Act.

8.   Non-competition and non-disclosure. The Partners represent and warrant
     that:

     a.   In executing this Agreement, they do not believe they are presently
          involved in, nor will become involved in, any conflict of interest
          situation that would prevent them from acting in the Liska's best
          interests. In this regard the Partners will identify all such present
          contract activities they may have underway in the same general
          industry as Liska, for review and acceptance by Liska, and will not
          become involved in any future work of a potential conflicting nature
          without the express written consent of Liska in each case.

     b.   The Partners will not directly or indirectly  disclose or use, at any
          time, either during or subsequent to the termination or expiry of this
          Agreement, any secret or any confidential information or data of Liska
          unless it has first secured the Liska's written consent to such
          disclosure or use. This condition becomes null and void if such
          information has become publicly or generally available in any way
          other than through the actions of the Partners.

     c.   The provisions of these subparagraphs shall survive any expiration or
          termination of this Letter of Engagement.

9.   Termination. This agreement for services can be terminated unequivocally by
     either party with 30 days written notice, under the following terms and
     conditions.

     a.   Should Liska terminate this Agreement without cause prior to March 31,
          2005, then the said 400,000 shares held back by Liska in accordance
          with paragraph 7b (ii) herein shall immediately be given over to the
          Partners by Liska. If it is determined by the Company that termination
          is necessary for non-performance or for material misrepresentation, as
          determined solely by the board, then the Company reserves the right to
          hold the said 400,000 shares for cancellation and the Partners will
          agree not to contest the board's decision.

     b.   Should the Partners terminate this Agreement prior to the date of
          issuance of the additional 400,000 shares per paragraph 7b, then the
          entitlement to said shares by the Partners shall be considered
          abandoned by the Partners and Liska will not be under further
          obligation for such delivery.
