</TABLE>

----------------------

(1)     Amounts represented on an as converted basis from Canadian dollars to
        U.S. dollars. On April 17, 1998, the exchange rate was 1 Canadian dollar
        per US $0.6981.

(2)     For the sole purpose of calculating the registration fee, the number of
        shares to be registered under this Registration Statement has been
        broken down into subtotals. This subtotal represents the 1,041,700
        post-split shares issuable upon exercise of outstanding options (options
        that have been granted as of the date of this Registration Statement)
        issued under the 1987 Stock Option Plan.

(3)     Estimated in accordance with Rule 457(h) under the Securities Act of
        1933 solely for the purpose of calculating the total registration fee.
        Computation based on the weighted average exercise price (rounded to the
        nearest cent) at which the options whose exercise will result in the
        issuance of the shares being registered may be exercised.

(4)     Calculated in accordance with Rule 457(h) based on the aggregate
        exercise price for all presently outstanding options described in Note 2
        above.

(5)     This subtotal represents the 800,000 shares issuable under the 1997
        Employee Stock Option Plan.

(6)     Calculated in accordance with Rule 457(h) based on the aggregate
        exercise price for the number of shares issuable under the Plan
        described in Note 5 above.

(7)     This sub-total represents the 150,000 shares issuable under the 1997
        Non-Employee Stock Option Plan.

(8)     Estimated in accordance with Rule 457(h) under the Securities Act of
        1933 solely for the purpose of calculating the registration fee. The
        computation is based upon the closing price of the Company's shares as
        reported on the Nasdaq National Market on April 17, 1998 because the
        price at which options to be granted in the future may be exercised is
        not currently determinable.

(9)     The price per share computation of the 1997 Employee Stock Purchase Plan
        is based upon 85% of the average of the high and low price of the Common
        Stock as reported on Nasdaq National Market on April 17, 1998. Pursuant
        to the Employee Stock Purchase Plan, which plan is incorporated by
        reference herein, the Purchase Price of a share of Common Stock shall
        mean an amount equal to 85% of the Fair Market Value of a share of
        Common Stock on the Enrollment Date or the Exercise Date, whichever is
        lower.

(10)    Calculated in accordance with Rule 457(h) based on the aggregate
        exercise price for the number of shares issuable under the Plan
        described in Note 7 above.

(11)    This subtotal represents the 100,000 shares issuable under the 1997
        Stock Purchase Plan.

(12)    Calculated in accordance with Rule 457(h) based on the aggregate
        exercise price for the number of shares issuable under the Plan
        described in Note 11 above.

(13)    The Registration fee is calculated pursuant to the SEC appropriations
        bill (H.R. 2267) enacted to decrease the fee rate on filings made
        pursuant to Section 6(b) of the Securities Act of 1933. As of the most
        current SEC press release regarding fee rates, the fee is calculated by
        multiplying the aggregate offering amount by .000295. The fee rate was
        effective on November 28, 1997.

ITEM 9. UNDERTAKINGS.

        (a)    The undersigned Registrant hereby undertakes:

               (1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement to include any
material information with respect to the plan of distribution not previously
disclosed in the registration statement or any material change to such
information in the registration statement.

               (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

               (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

        (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

        (c) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being

                                       -3-

<PAGE>   6
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act of 1933 and will be governed by the
final adjudication of such issue.

(1)     Amounts represented on an as converted basis from Canadian dollars to
        U.S. dollars. On April 17, 1998, the exchange rate was 1 Canadian dollar
        per US $0.6981.

(2)     For the sole purpose of calculating the registration fee, the number of
        shares to be registered under this Registration Statement has been
        broken down into subtotals. This subtotal represents the 1,041,700
        post-split shares issuable upon exercise of outstanding options (options
        that have been granted as of the date of this Registration Statement)
        issued under the 1987 Stock Option Plan.

(3)     Estimated in accordance with Rule 457(h) under the Securities Act of
        1933 solely for the purpose of calculating the total registration fee.
        Computation based on the weighted average exercise price (rounded to the
        nearest cent) at which the options whose exercise will result in the
        issuance of the shares being registered may be exercised.

(4)     Calculated in accordance with Rule 457(h) based on the aggregate
        exercise price for all presently outstanding options described in Note 2
        above.

(5)     This subtotal represents the 800,000 shares issuable under the 1997
        Employee Stock Option Plan.

(6)     Calculated in accordance with Rule 457(h) based on the aggregate
        exercise price for the number of shares issuable under the Plan
        described in Note 5 above.

(7)     This sub-total represents the 150,000 shares issuable under the 1997
        Non-Employee Stock Option Plan.

(8)     Estimated in accordance with Rule 457(h) under the Securities Act of
        1933 solely for the purpose of calculating the registration fee. The
        computation is based upon the closing price of the Company's shares as
        reported on the Nasdaq National Market on April 17, 1998 because the
        price at which options to be granted in the future may be exercised is
        not currently determinable.

(9)     The price per share computation of the 1997 Employee Stock Purchase Plan
        is based upon 85% of the average of the high and low price of the Common
        Stock as reported on Nasdaq National Market on April 17, 1998. Pursuant
        to the Employee Stock Purchase Plan, which plan is incorporated by
        reference herein, the Purchase Price of a share of Common Stock shall
        mean an amount equal to 85% of the Fair Market Value of a share of
        Common Stock on the Enrollment Date or the Exercise Date, whichever is
        lower.

(10)    Calculated in accordance with Rule 457(h) based on the aggregate
        exercise price for the number of shares issuable under the Plan
        described in Note 7 above.

(11)    This subtotal represents the 100,000 shares issuable under the 1997
        Stock Purchase Plan.

(12)    Calculated in accordance with Rule 457(h) based on the aggregate
        exercise price for the number of shares issuable under the Plan
        described in Note 11 above.

(13)    The Registration fee is calculated pursuant to the SEC appropriations
        bill (H.R. 2267) enacted to decrease the fee rate on filings made
        pursuant to Section 6(b) of the Securities Act of 1933. As of the most
        current SEC press release regarding fee rates, the fee is calculated by
        multiplying the aggregate offering amount by .000295. The fee rate was
        effective on November 28, 1997.

in good faith with a view to the best interests of the Company, and, in the case

ITEM 9. UNDERTAKINGS.

        (a)    The undersigned Registrant hereby undertakes:

               (1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement to include any
material information with respect to the plan of distribution not previously
disclosed in the registration statement or any material change to such
information in the registration statement.

               (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

               (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

        (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

        (c) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being

                                       -3-

registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act of 1933 and will be governed by the
final adjudication of such issue.
