     of the  Exchange  Act,  including  any  amendment  or report  filed for the
     purpose of updating such description.

All documents  filed by the Registrant  pursuant to Section 13(a),  13(c), 14 or
15(d) of the  Exchange  Act after the date  hereof  and prior to the filing of a
post-effective  amendment which indicates that all securities  offered have been

Item 6.  Indemnification of Directors and Officers.

The  By-laws of the  Registrant  provide  that,  subject to the Canada  Business
Corporation  Act (the  "CBCA"),  the  Registrant  shall  indemnify a director or
officer of the  Registrant,  a former director of officer of the Registrant or a
person who acts or acted at the Registrant's request as a director or officer of
a body  corporate of which the  Registrant is or was a shareholder  or creditor,
and his heirs and legal representatives, against all costs, charges and expenses
reasonably incurred by him in respect of certain actions or proceedings to which
he is made a party  by  reason  of his  office,  if he meets  certain  specified
standards  of  conduct  and  shall  also  indemnify  any  such  person  in  such
circumstances as the CBCA or law permits or requires.

Under the CBCA, except in respect of an action by or on behalf of the Registrant
to procure a judgment in its favor,  the  Registrant  may indemnify a present or
former  director  or  officer  or a person  who  acts or acted at the  Company's

action or  satisfy a  judgment,  reasonably  incurred  by him in  respect to any
civil,  criminal or  administrative  action or  proceeding to which he is made a

director  or officer  acted  honestly  and in good faith with a view to the best
interests of the Registrant,  and, in the case of a criminal,  or administrative
action or  proceeding  that is enforced by a monetary  penalty,  has  reasonable
grounds for believing that his conduct was lawful.  Such  indemnification may be
made in connection with a derivative action




                                      II-1

the merits and fulfilled the conditions set forth above.

The Registrant  maintains  Directors' and Officers'  Liability Insurance for its
Directors.

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:

               (i)       To include any prospectus  required by Section 10(a)(3)
of the Securities Act;

               (ii)      To  reflect  in the  prospectus  any  facts  or  events
arising  after the  effective  date of the  registration  statement (or the most
recent  post-effective   amendment  thereof)  which,   individually  or  in  the
aggregate,  represent a fundamental  change in the  information set forth in the
registration statement.  Notwithstanding the foregoing, any increase or decrease
in volume of securities offered (if the total dollar value of securities offered
would not exceed that which was  registered)  and any deviation  from the low or
high and of the estimated maximum offering range may be reflected in the form of
prospectus  filed  with  the  Commission  pursuant  to Rule  424(b)  if,  in the
aggregate,  the change in volume and price represents no more than 20% change in
the  maximum  aggregate   offering  price  set  forth  in  the  "Calculation  of
Registration Fee" table in the effective registration statement;

               (iii)     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;

provided,  however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
registration statement is on Form S-3, Form S-8, or Form F-3 and the information
required to be included in a  post-effective  amendment by those  paragraphs  is
contained in periodic  reports filed with or furnished to the  Commission by the
Registrant  pursuant to Section 13 or Section 15(d) of the Exchange Act that are
incorporated by reference in this registration statement.

          (2) That for the  purpose  of  determining  any  liability  under  the
Securities Act, 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.




                                      II-2
<PAGE>

          (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,  each  filing  of  the
Registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Exchange Act, (and, where applicable,  each filing of an employee benefit plan's
annual  report   pursuant  to  section  15(d)  of  the  Exchange  Act)  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 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 Securities 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
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  of whether  such  indemnification  by it is against
public  policy  as  expressed  in the Act  and  will be  governed  by the  final
adjudication of such issue.

     purpose of updating such description.

All documents  filed by the Registrant  pursuant to Section 13(a),  13(c), 14 or
15(d) of the  Exchange  Act after the date  hereof  and prior to the filing of a

Item 6.  Indemnification of Directors and Officers.

The  By-laws of the  Registrant  provide  that,  subject to the Canada  Business
Corporation  Act (the  "CBCA"),  the  Registrant  shall  indemnify a director or
officer of the  Registrant,  a former director of officer of the Registrant or a
person who acts or acted at the Registrant's request as a director or officer of
a body  corporate of which the  Registrant is or was a shareholder  or creditor,
and his heirs and legal representatives, against all costs, charges and expenses
reasonably incurred by him in respect of certain actions or proceedings to which
he is made a party  by  reason  of his  office,  if he meets  certain  specified
standards  of  conduct  and  shall  also  indemnify  any  such  person  in  such
circumstances as the CBCA or law permits or requires.

Under the CBCA, except in respect of an action by or on behalf of the Registrant
to procure a judgment in its favor,  the  Registrant  may indemnify a present or
former  director  or  officer  or a person  who  acts or acted at the  Company's
request as a director or officer of another  corporation of which the Registrant
is or was a shareholder  or creditor,  and his heirs and legal  representatives,
against all costs,  charges and expenses,  including an amount paid to settle an
action or  satisfy a  judgment,  reasonably  incurred  by him in  respect to any
civil,  criminal or  administrative  action or  proceeding to which he is made a
party by  reason of his  position  with the  Registrant  and  provided  that the
director  or officer  acted  honestly  and in good faith with a view to the best
interests of the Registrant,  and, in the case of a criminal,  or administrative
action or  proceeding  that is enforced by a monetary  penalty,  has  reasonable
grounds for believing that his conduct was lawful.  Such  indemnification may be
made in connection with a derivative action

                                      II-1
only with court approval.  A director or officer is entitled to  indemnification
from the Registrant as a matter of right if he was  substantially  successful on
the merits and fulfilled the conditions set forth above.

The Registrant  maintains  Directors' and Officers'  Liability Insurance for its
Directors.

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:

               (i)       To include any prospectus  required by Section 10(a)(3)
of the Securities Act;

               (ii)      To  reflect  in the  prospectus  any  facts  or  events
arising  after the  effective  date of the  registration  statement (or the most
recent  post-effective   amendment  thereof)  which,   individually  or  in  the
aggregate,  represent a fundamental  change in the  information set forth in the
registration statement.  Notwithstanding the foregoing, any increase or decrease
in volume of securities offered (if the total dollar value of securities offered
would not exceed that which was  registered)  and any deviation  from the low or
high and of the estimated maximum offering range may be reflected in the form of
prospectus  filed  with  the  Commission  pursuant  to Rule  424(b)  if,  in the
aggregate,  the change in volume and price represents no more than 20% change in
the  maximum  aggregate   offering  price  set  forth  in  the  "Calculation  of
Registration Fee" table in the effective registration statement;

               (iii)     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;

provided,  however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
registration statement is on Form S-3, Form S-8, or Form F-3 and the information
required to be included in a  post-effective  amendment by those  paragraphs  is
contained in periodic  reports filed with or furnished to the  Commission by the
Registrant  pursuant to Section 13 or Section 15(d) of the Exchange Act that are
incorporated by reference in this registration statement.

          (2) That for the  purpose  of  determining  any  liability  under  the
Securities Act, 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.

                                      II-2
(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,  each  filing  of  the
Registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Exchange Act, (and, where applicable,  each filing of an employee benefit plan's
annual  report   pursuant  to  section  15(d)  of  the  Exchange  Act)  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 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 Securities 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
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  of whether  such  indemnification  by it is against
public  policy  as  expressed  in the Act  and  will be  governed  by the  final
adjudication of such issue.
