Agreement, Employer hereby employs Employee and Employee hereby accepts
employment with Employer for a term beginning on the Effective Date as set
forth above through and including June 19, 2000 (the "INITIAL TERM"), unless

duties for which he currently is responsible as an employee of Employer and/or
any duties set forth in any job description provided by Employer.  In addition,
Employee shall perform other duties as may from time to time be prescribed by
Employer's Board of Directors or more senior management and which are

Employer.  Employee shall perform his duties hereunder in accordance with any
lawful instructions, rules, regulations or policies made or adopted by
Employer's Board of Directors or more senior management, including those
applicable to Employer's employees generally.  During the Employment Period,
Employee shall devote his full time, and best efforts and skills to the

Employee shall project a positive and professional image on behalf of Employer.

accurately make, maintain and preserve all records and reports that Employer
may from time to time request or require.  Employee shall fully account for all
money, records, goods, wares and merchandise or other property belonging to
Employer or its "AFFILIATES" (as that term is defined in Rule 405 under the
Securities Act of 1933, as amended) of which he may have custody and will pay
over and deliver the same promptly whenever and however he may be directed to
do so.  Employee also shall make available to Employer any and all information
of which he has knowledge that is relevant to Employer's business, and will
make all suggestions and recommendations which he feels will be of benefit to
Employer.  Employee shall, upon Employer's written request, furnish all
information and take any other steps necessary to enable Employer to obtain a
fidelity bond conditioned on the rendering of a true account by Employee of all
moneys, goods or other property which may come into the custody, charge or
possession of Employee during the Employment Period.  The surety company
issuing the bond and the amount of the bond must be acceptable to Employer in
its sole discretion.  Employer shall pay all premiums on any such bond.

believes that any other employee of the Employer is or appears to be (i)
removing or using the property or funds of Employer or its Affiliates for the
benefit of anyone other than Employer or its Affiliates, or (ii) providing
Confidential Information (as defined in Section 3.2) to any person not
authorized by Employer to receive such Confidential Information (any such
employee described in (i) or (ii) being referred to as a "DISHONEST EMPLOYEE"),
Employee shall immediately communicate his knowledge or belief as to such
matters to Employer's Board of Directors.  Employee acknowledges and agrees
that he shall be conclusively presumed to be in complicity with such Dishonest
Employee if Employee does not so disclose his knowledge or belief as to such
matters to Employer's Board of Directors.

       1.5  FIDUCIARY DUTIES OF EMPLOYEE.  The obligations of Employee
expressed in this Agreement shall be in addition to any obligations imposed
upon Employee as an employee or officer of Employer or its Affiliates by
Company's Policies and Procedures, as amended, the law of  the Province of
Alberta applicable to employees, the General Corporation Law of the Province of
Alberta applicable to corporate officers, or federal law which limit the
activities of an employee or corporate officer to those which will not
threaten, impair or usurp the goodwill, trade secrets, intellectual property,
business opportunities, and business relations of his employer.

       1.6  PLACE OF PERFORMANCE.  Employee shall perform his duties hereunder

              plan , as mutually agreed upon by the parties, shall be prepared
              which will make a bonus of thirty-three and one third percent (33
              1/3%) of base compensation payable at the completion of the first
              year of this Agreement if all bonus plan criteria are met;

       (b)    participation in any present or future disability, medical,
              health, dental, insurance, pension, profit-sharing, thrift,

              other benefit, bonus or compensation plans on the same terms

              business expenses (within limits that may be established by
              Employer's Board of Directors) incurred in connection with the
              performance of his duties hereunder, such expense payment or

              entitled to use said condominium for such purpose if said
              condominium is available; and

       (g)    as separate consideration to Employee for entering into the
              covenants and restrictions set forth in Article 4, Employer
              agrees to pay Employee, on the Effective Date, a signing bonus in
              the amount of Ten Thousand Dollars U.S. ($10,000.00 U.S.).

vacation time in such amounts and at such times as determined by Employer's
Board of Directors, in its sole discretion; provided, however, that the minimum

Employee could reasonably have been expected to acquire in similar work with
another company.  The phrase "PUBLICLY KNOWN" shall mean readily accessible to
the public in a written publication, shall not include information which is
only available by a substantial searching of the published literature or
information the substance of which must be pieced together from a number of
different publications and sources.  The burden of proving that information or
skills and experience are not Confidential Information shall be on the party
asserting such exclusion.

       3.4  COVENANTS OF EMPLOYEE.  As a consequence of Employee's acquisition
or anticipated acquisition of Confidential Information, Employee will occupy a
position of trust and confidence with respect to Employer's affairs and
business.  In view of the foregoing and of the consideration to be provided to
Employee, Employee agrees that it is reasonable and necessary that Employee
make the following covenants:

       (a)    At any time during or after the termination of the Employment
              Period, Employee will not disclose Confidential Information to
              any person or entity, either inside or outside of Employer, other
              than as necessary in carrying out duties on behalf of Employer,
              without obtaining Employer's prior written consent (unless such
              disclosure is compelled pursuant to court order or subpoena, and
              at which time Employee gives notice of such proceedings to
              Employer), and Employee will take all reasonable precautions to
              prevent inadvertent disclosure of such Confidential Information.
              This prohibition against Employee's disclosure of Confidential
              Information includes, but is not limited to, disclosing the fact
              that any similarity exists between the Confidential Information
              and information independently developed by another person or
              entity, and Employee understands that such similarity does not
              excuse Employee





Ramsay Employment Agreement
June 20, 1997
Page 6
<PAGE>   7
              from abiding by his covenants or other obligations under this
              Agreement.

       (b)    At any time during or after the termination of the Employment
              Period, Employee will not use, copy or transfer Confidential
              Information other than as necessary in carrying out his duties on
              behalf of Employer, without first obtaining Employer's prior
              written consent, and will take all reasonable precautions to
              prevent inadvertent use, copying or transfer of such Confidential
              Information.  This prohibition against Employee's use, copying,
              or transfer of Confidential Information includes, but is not
              limited to, selling, licensing or otherwise exploiting, directly
              or indirectly, any products or services (including data bases,
              written documents and software in any form) which embody or are
              derived from Confidential Information, or exercising judgment in
              performing analyses based upon knowledge of Confidential
              Information.

       3.5  RETURN OF CONFIDENTIAL MATERIAL.  Employee shall turn over to
Employer all originals and copies of materials containing Confidential
Information in the Employee's possession, custody, or control upon request or
upon termination of the Employee's employment with Employer.  Employee agrees
to attend a termination interview with the Executive Compensation Committee of
Employer's Board of Directors to confirm turnover of such materials and to
discuss any questions the undersigned may have about his continuing obligations
under this Agreement.

       3.6  INVENTIONS.  Any and all inventions, products, discoveries,
improvements, copyrightable works, trademarks, service marks, ideas, processes,
formulae, methods, designs, techniques or trade secrets (collectively
hereinafter referred to as "INVENTIONS") made, developed, conceived or
resulting from work performed by Employee (alone or in conjunction with others,
during regular hours of work or otherwise) while he is employed by Employer and
which may be directly or indirectly useful in, or related to, the business of
Employer (including, without limitation, research and development activities of
Employer), or which are made using any equipment, facilities, Confidential
Information, materials, labor, money, time or other resources of Employer,
shall be promptly disclosed by Employee to Employer's Board of Directors, shall
be deemed Confidential Information for purposes of this Agreement, and shall be
Employer's exclusive property.  Employee shall, upon Employer's request,
execute any documents and perform all such acts and things which are necessary
or advisable in the opinion of Employer to cause issuance of patents to, or
otherwise obtain recorded protection of right to intellectual property for,
Employer with respect to Inventions that are to be Employer's exclusive
property under this Section 3.6, or to transfer to and vest in Employer full
and exclusive right, title and interest in and to such Inventions; provided,
however, that the expense of securing any such protection of right to
Inventions shall be borne by Employer.  In addition, Employee shall, at
Employer's expense, assist Employer in any proper manner in enforcing any
Inventions which are to be or become Employer's exclusive property hereunder
against infringement by others.  Employee shall keep confidential and will hold
for Employer's sole use and benefit any Invention that is to be Employer's
exclusive property under this Section 3.6 for which full recorded protection of
right has not been or cannot be obtained.

              records, contracts, patents, technology and associated trade
              secrets and know-how, perform his obligations under this
              Agreement, and after receiving further training by and experience
              with Employer, and after reviewing Employer's trade secrets,
              become a competitor;

       (g)    Employer will suffer great loss and irreparable harm if Employee
              terminates his employment and enters directly or indirectly, into
              competition with Employer;

       (h)    the temporal and other restrictions contained in this Article 4
              are in all respects reasonable and necessary to protect the
              business goodwill, trade secrets, prospects and other business
              interests of Employer;

       (i)    the enforcement of this Agreement in general, and of this Article
              4 in particular, will not work an undue or unfair hardship on
              Employee or otherwise be oppressive to him, it being specifically
              acknowledged and agreed by Employee that he has activities and
              other business interests and opportunities which will provide him
              adequate means of support if the provisions of this Article 4 are
              enforced after





Ramsay Employment Agreement
June 20, 1997

<PAGE>   10
              termination of his employment with Employer; and

       (j)    the enforcement of this Agreement in general, and of this Article
              4 in particular, will neither deprive the public of needed goods
              or services nor otherwise be injurious to the public.

       4.4  JUDICIAL MODIFICATION.  Employee agrees that if a court of
competent jurisdiction determines that the length of time or any other
restriction, or portion thereof, set forth in this Article 4 is overly
restrictive and unenforceable, the court may reduce or modify such restrictions
to those which it deems reasonable and enforceable under the circumstances, and
as so reduced or modified, the parties hereto agree that the restrictions of
this Article 4 shall remain in full force and effect.  Employee further agrees
that if a court of competent jurisdiction determines that any provision of this
Article 4 is invalid or against public policy, the remaining provisions of this
Article 4 and the remainder of this Agreement shall not be affected thereby,
and shall remain in full force and effect.

       4.5  SURVIVAL OF COVENANTS.  The covenants and agreements of Employee
set forth in this Article 4 are of a continuing nature and shall survive the
expiration, termination or cancellation of the remainder of this Agreement
regardless of the reason for such therefor and shall survive the termination,
if any, of the Employee's employment.

                                   ARTICLE 5
                                  TERMINATION

       5.1  EMPLOYER TERMINATION

       (a)    Notwithstanding any other provision of this Agreement, at any
              time during the Employment Period, including, without limitation,
              the Initial Term, this Agreement and Employee's employment
              hereunder shall terminate upon his death, and Employer shall have
              the right, in its sole and absolute discretion, to terminate this
              Agreement and Employee's employment hereunder at any time by
              giving him written notice of such termination (i) for "Cause" (as
              defined below), (ii) if Employee shall fail to qualify for the
              fidelity bond described in Section 1.3 within sixty (60) days
              from the date of the Employer's written request thereunder, or
              (iii) if Employee shall suffer a Disability (as defined below).

       (b)    "CAUSE" shall mean any of the following events:

              (1)    Employee's conviction or the entry of a plea of guilty or
                     nolo contendere or equivalent plea in a court of competent
                     jurisdiction of any crime or offense involving moral
                     turpitude or any felony;

              (2)    Employee's commission of an act of fraud upon Employer or
                     any of its





Ramsay Employment Agreement

<PAGE>   11
                     Affiliates;

              (3)    Employee's willful misappropriation of funds or property
                     of Employer or any of its Affiliates;

              (4)    Employee's knowing engagement, without prior approval by
                     resolution of Employer's Board of Directors, in any direct
                     conflict of interest with Employer or any of its
                     Affiliates, in any activity which would constitute a
                     breach of Employee's representations, covenants,
                     agreements and obligations under Articles 3 and 4 of this
                     Agreement, or which would otherwise result in substantial
                     injury to Employer's business or financial condition;

              (5)    Employee's refusal to perform his duties under Article 1
                     of this Agreement; or

              (6)    Employee's habitual use of alcohol or drugs which, in the
                     reasonable opinion of Employer, substantially impairs the
                     performance of Employee's duties.

       (c)    "DISABILITY" shall mean any mental or physical illness,
              impairment or condition which, in the sole opinion of Employer:
              (i) is of a nature that cannot reasonably be controlled by
              Employee, (ii) significantly inhibits or impedes Employee's
              ability to perform the services required under this Agreement,
              and (iii) is likely to be either long-lasting in duration or
              recurring from time to time.

       5.2  TERMINATION BY EITHER PARTY.  Subject to the provisions of Section
5.3(a), Employer may at any time, for any reason, with or without Cause,
terminate this Agreement and Employee's employment hereunder.  After expiration
of the Initial Term, Employee may terminate this Agreement and his employment
hereunder without regard to any reason for such termination.  Each of
Employer's and Employee's option to terminate this Agreement pursuant to this
Section 5.2 shall be exercised by delivery of a written notice to Employee or
Employer, as applicable, specifying the effective date of such termination
which in no event shall be sooner than expiration of thirty (30) calendar days
following delivery of such written notice.

       5.3  EFFECT OF TERMINATION.

       (a)    If Employer terminates this Agreement for any reason other than
              pursuant to the terms of Section 5.1, then Employer shall pay to
              Employee an amount equal to the greater of (a) his total Base
              Salary for the remainder of the Employment Period, or (b) which
              shall be the greater of (i)three months of his Base Salary or
              (ii) one month of Base Salary for each full year of service
              completed with Employer as of the date of termination.  Employer
              may, in its sole and absolute discretion, make such payment in
              the manner and on the timetable specified in Section 2.1, or in
              one lump





Ramsay Employment Agreement

<PAGE>   12
              sum on the effective date of termination.

       (b)    Subject to the provisions of Section 5.3(a), upon termination of
              this Agreement and Employee's employment hereunder by either
              Employer or Employee, Employee shall have no right to receive any
              compensation or benefits for any period subsequent to the
              effective date of such termination, or for any period prior to
              such date which have not been earned or vested as of such date.

       (c)    Employer's right of termination shall be in addition to and shall
              not affect Employee's rights and remedies under Articles 3 and 4,
              and Section 6.1 of this Agreement, and such rights and remedies
              shall survive termination of Employee's employment hereunder.

       5.4  YEARS OF SERVICE.  For purposes of this Article Five, any reference
to Employee's year(s) of service shall include (i) service with the Employer,
(ii) service with any Affiliate of Employer, and (iii) service with any
predecessor entity of Employer whether by merger, acquisition or operation of
law.

                                   ARTICLE 6
                                 MISCELLANEOUS

       6.1  INJUNCTIVE RELIEF.  Because of the unique nature of the
Confidential Information, Employee acknowledges, understands and agrees that
Employer will suffer immediate and irreparable harm if Employee fails to comply
with any of his obligations under Articles 3 or 4 of this Agreement, and that
monetary damages will be inadequate to compensate Employer for such breach.
Accordingly, Employee agrees that Employer shall, in addition to any other
remedies available to it at law or in equity, be entitled to temporary,
preliminary, and permanent injunctive relief to enforce the terms of Articles 3
and 4 without the necessity of proving inadequacy of legal remedies or
irreparable harm.

       6.2  INDEMNIFICATION.  Employer shall indemnify Employee in the same
manner and to the same extent that Employer is obligated to indemnify its
directors pursuant to Employer's Certificate of Incorporation and Bylaws, as
each may be amended or restated from time to time.

       6.3  ACTION BY AND CONSENT OF EMPLOYER.  All rights and remedies of
Employer hereunder shall be exercised by the Employer solely by and through
management authorized by Employer's Board of Directors.

       6.4  NOTICES.  Any notice, instruction, authorization, request or demand
required hereunder shall be in writing, and shall be delivered either by
personal delivery, by telegram, telex, telecopy or similar facsimile means, by
certified or registered mail, return receipt requested, or by courier or
delivery service, addressed to the parties hereto at the principal offices of
Employer at the address





Ramsay Employment Agreement

indicated beneath its signature on the execution page of this Agreement, and
also to Employee at his home address indicated beneath his signature on the
execution page of this Agreement, or at such other address and number as a
party shall have previously designated by written notice given to the other
party in the manner hereinabove set forth.  Notices shall be deemed given when
received, if sent by facsimile means (confirmation of such receipt by confirmed
facsimile transmission being deemed receipt of communications sent by facsimile
means); and when delivered and receipted for (or upon the date of attempted
delivery where delivery is refused), if hand-delivered, sent by express courier
or delivery service, or sent by certified or registered mail, return receipt
requested.

       6.5  AMENDMENT AND WAIVER.  This Agreement may be amended, modified or
superseded only by written instrument executed by all parties hereto.  Any
waiver of the terms, provisions, covenants, representations, warranties, or
conditions hereof shall be made only by a written instrument executed and
delivered by the party waiving compliance.  Any waiver granted by Employer
shall be effective only if executed and delivered by a duly authorized
executive officer of Employer other than Employee.  The failure of any party at
any time or times to require performance of any provisions hereof, shall in no
manner effect the right to enforce the same.  No waiver by any party of any
condition or provision, or the breach of any term, provision, representation,
or warranty contained in this Agreement in one or more instances shall be
deemed to be or construed as a further or continuing waiver of any such
condition or breach or a waiver of any other condition or the breach of any
other term, provision, covenant, representation, or warranty.

       6.6  SUCCESSORS AND ASSIGNS.  All of the terms, provisions, covenants,
representations, warranties, and conditions of this Agreement shall bind, be
enforceable by, and inure to the benefit of, the parties hereto, but this
Agreement and the rights and obligations hereunder shall not be assignable or
delegable by any party; provided, however, that this Agreement and all of
Employer's rights and obligations hereunder may be assigned or delegated by it,
in whole, but not in part, to, and shall be binding upon and inure to the
benefit of, any of its successors or assigns, but such assignment or delegation
by Employer shall not relieve it of any of its obligations hereunder.

       6.7  DEFINITIONS, GENDER AND CERTAIN REFERENCES.  As used in this
Agreement, each parenthetically or quoted capitalized term in the introduction,
recitals and other Sections of this Agreement shall have the meaning so
ascribed to it.  Whenever the context requires, the gender of all words used
herein shall include the masculine, feminine and neuter, and the number of all
words shall include the singular and plural.  References to Articles or
Sections shall be to Articles or Sections of this Agreement unless otherwise
specified.  The headings and captions used in this Agreement are solely for
convenient reference and shall not affect the meaning or interpretation of any
article, section or paragraph herein, or this Agreement.  The terms "hereof,"
"herein" or "hereunder" shall refer to this Agreement as a whole and not to any
particular Section.

       6.8  GOVERNING LAW AND SEVERABILITY.  The validity, interpretation,
construction, and performance of this Agreement shall be governed by the
internal law, and not the law of conflicts, of the Province of Alberta.  Each
party hereto hereby acknowledges and agrees that it has had the





Ramsay Employment Agreement
June 20, 1997
Page 13
<PAGE>   14
opportunity to consult with its own legal counsel in connection with the
negotiation of this Agreement, and that it has bargaining power equal to that
of the other party hereto in connection with the negotiation, execution and
delivery of this Agreement.  Accordingly, the parties hereto agree that the
rule of contract construction that an agreement shall be construed against the
drafter shall have no application in the construction or interpretation of this
Agreement.  The invalidity of any provision of this Agreement shall not affect
any other provision of this Agreement, which shall remain in full force and
effect, nor shall the invalidity of a portion of any provision of this
Agreement affect the balance of such provision.

       6.9  EXPENSES.  Each party hereto shall pay all of its respective fees
and expenses of attorneys, accountants and other persons employed by it in
connection with the resolution of any dispute between the parties hereto
arising out of or relating to this Agreement, except for any indemnification
obligations of Employer pursuant to Section 6.2.

       6.10  ENTIRE AGREEMENT.  No agreements or representations, oral or
otherwise, express or implied, have been made by any party hereto with respect
to the subject matter hereof that are not set forth expressly in this
Agreement.  This Agreement supersedes and cancels any prior agreement,
arrangement or understanding entered into between Employer and Employee
relating to the subject matter hereof.

       6.11  COUNTERPARTS.  The parties may execute this Agreement in any
number of counterparts, each of which is an original, but all of which together
constitute one and the same instrument.

       IN WITNESS WHEREOF, the parties have caused this Agreement to be
executed on the date first above written.
