              In addition,  all documents  subsequently  filed by the Registrant

ITEM 5.       INTERESTS OF NAMED EXPERTS AND COUNSEL

              Not applicable.

ITEM 6.       INDEMNIFICATION OF DIRECTORS AND OFFICERS

              Under the  Canada  Business  Corporations  Act (the  "CBCA"),  the
Registrant  may  indemnify  a  present  or former  director  or  officer  of the
Registrant or another  individual who acts or acted at the Registrant's  request
as a director or officer,  or an  individual  acting in a similar  capacity,  of
another  entity,  against all costs,  charges and expenses,  including an amount

<PAGE>

paid to settle an action or  satisfy  a  judgment,  reasonably  incurred  by the
individual in respect of any civil, criminal,  administrative,  investigative or
other proceeding in which the individual is involved because of that association
with the  Registrant  or other  entity.  The  Registrant  may not  indemnify  an
individual unless the individual acted honestly and in good faith with a view to
the best  interests  of the  Registrant,  or,  as the  case may be,  to the best
interests  of the other entity for which the  individual  acted as a director or
officer or in a similar capacity at the Registrant's  request and in the case of
a criminal or administrative action or proceeding that is enforced by a monetary
penalty,   the  individual  had  reasonable   grounds  for  believing  that  the
individual's  conduct was lawful. The  indemnification may be made in connection
with  a  derivative  action  only  with  court  approval.   The   aforementioned
individuals are entitled to  indemnification  from the Registrant as a matter of
right  against  all costs,  charges  and  expenses  reasonably  incurred by such
individuals   in   connection   with  the   defence  of  any  civil,   criminal,
administrative,  investigative or other  proceeding,  if they were not judged by
the court or other competent authority to have committed any fault or omitted to
do anything  that the  individual  ought to have done and,  if they  fulfill the
conditions  set out above.  The  Registrant may advance moneys to the individual
for the costs,  charges and expenses of a proceeding;  however,  the  individual
shall repay the moneys if the individual does not fulfill the conditions set out
above.

             The  by-laws  of  the  Registrant  provide  that,  subject  to  the
limitations  contained  in the  CBCA  (which  are  summarized  in the  foregoing
paragraph)  but without  limit to the right of the  Registrant  to indemnify any
person  under  the  CBCA  or  otherwise,  the  Registrant  shall  indemnify  the
aforementioned individuals against all costs, charges and expenses, including an
amount  paid to settle an action or satisfy a judgment  reasonably  incurred  by
such   individuals   in  respect  of  any   civil,   criminal,   administrative,
investigative or other proceeding in which such individuals are involved because
of that association with the Registrant or other entity.

             The by-laws of the  Registrant  provide  that the  Registrant  may,
subject to the CBCA, purchase, maintain or participate in such insurance for the
benefit  of the  aforementioned  individuals  as the Board of  Directors  of the
Registrant may from time to time  determine.  The Registrant has purchased third
party director and officer liability insurance.

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, each such post-effective  amendment shall be deemed to
be a new Registration  Statement relating to the securities offered therein, and

<PAGE>

the offering of such  securities  at that time shall be deemed to be the initial
bona fide offering thereof; and

                       (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  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 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 whether
such  indemnification  by it is  against  public  policy  as  expressed  in  the
Securities Act and will be governed by the final adjudication of such issue.

certifies  that it has  reasonable  grounds to believe  that it meets all of the
requirements  for  filing  on Form S-8 and has  duly  caused  this  registration
statement  to be  signed  on its  behalf  by  the  undersigned,  thereunto  duly
authorized, in the City of Calgary, Province of Alberta, on February 23, 2007.

                      Registrant document referred to in 1. above.

              In addition,  all documents  subsequently  filed by the Registrant

ITEM 5.       INTERESTS OF NAMED EXPERTS AND COUNSEL

              Not applicable.

ITEM 6.       INDEMNIFICATION OF DIRECTORS AND OFFICERS

              Under the  Canada  Business  Corporations  Act (the  "CBCA"),  the
Registrant  may  indemnify  a  present  or former  director  or  officer  of the
Registrant or another  individual who acts or acted at the Registrant's  request
as a director or officer,  or an  individual  acting in a similar  capacity,  of
another  entity,  against all costs,  charges and expenses,  including an amount
paid to settle an action or  satisfy  a  judgment,  reasonably  incurred  by the
individual in respect of any civil, criminal,  administrative,  investigative or
other proceeding in which the individual is involved because of that association
with the  Registrant  or other  entity.  The  Registrant  may not  indemnify  an
individual unless the individual acted honestly and in good faith with a view to
the best  interests  of the  Registrant,  or,  as the  case may be,  to the best
interests  of the other entity for which the  individual  acted as a director or
officer or in a similar capacity at the Registrant's  request and in the case of
a criminal or administrative action or proceeding that is enforced by a monetary
penalty,   the  individual  had  reasonable   grounds  for  believing  that  the
individual's  conduct was lawful. The  indemnification may be made in connection
with  a  derivative  action  only  with  court  approval.   The   aforementioned
individuals are entitled to  indemnification  from the Registrant as a matter of
right  against  all costs,  charges  and  expenses  reasonably  incurred by such
individuals   in   connection   with  the   defence  of  any  civil,   criminal,
administrative,  investigative or other  proceeding,  if they were not judged by
the court or other competent authority to have committed any fault or omitted to
do anything  that the  individual  ought to have done and,  if they  fulfill the
conditions  set out above.  The  Registrant may advance moneys to the individual
for the costs,  charges and expenses of a proceeding;  however,  the  individual
shall repay the moneys if the individual does not fulfill the conditions set out
above.

             The  by-laws  of  the  Registrant  provide  that,  subject  to  the
limitations  contained  in the  CBCA  (which  are  summarized  in the  foregoing
paragraph)  but without  limit to the right of the  Registrant  to indemnify any
person  under  the  CBCA  or  otherwise,  the  Registrant  shall  indemnify  the
aforementioned individuals against all costs, charges and expenses, including an
amount  paid to settle an action or satisfy a judgment  reasonably  incurred  by
such   individuals   in  respect  of  any   civil,   criminal,   administrative,
investigative or other proceeding in which such individuals are involved because
of that association with the Registrant or other entity.

             The by-laws of the  Registrant  provide  that the  Registrant  may,
subject to the CBCA, purchase, maintain or participate in such insurance for the
benefit  of the  aforementioned  individuals  as the Board of  Directors  of the
Registrant may from time to time  determine.  The Registrant has purchased third
party director and officer liability insurance.

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, 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; and

                       (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  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 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 whether
such  indemnification  by it is  against  public  policy  as  expressed  in  the
Securities Act and will be governed by the final adjudication of such issue.
SIGNATURES

              Pursuant to the requirements of the Securities Act, the registrant
certifies  that it has  reasonable  grounds to believe  that it meets all of the
requirements  for  filing  on Form S-8 and has  duly  caused  this  registration
statement  to be  signed  on its  behalf  by  the  undersigned,  thereunto  duly
authorized, in the City of Calgary, Province of Alberta, on February 23, 2007.
