<PAGE>


         (a)   against all costs, charges and expenses, including an amount
               paid to settle an action or satisfy a judgment, reasonably
               incurred by him or her in respect of any civil, criminal or
               administrative action or proceeding to which he or she is made a
               party be reason of being or having been a director or officer of

         (b)   with court approval, against all costs, charges and expenses
               reasonably incurred by him or her in connection with an action
               brought by or on behalf of the Registrant or body corporate to
               procure a judgment in its favor, to which he or she is made a
               party by reason of being or having been a director or officer
               of the Registrant or body corporate; and

         (c)   in respect of all costs, charges and expenses reasonably
               incurred by him or her in connection with the defense of any
               civil, criminal or administrative action or proceeding to which
               he or she is made a party by reason of having been a director
               or officer of the Registrant or body corporate, if he or she
               was substantially successful on the merits of his or her
               defense of the action or proceeding;

PROVIDED, in all cases, such director or officer (i) acted honestly and in good
faith with a view to the best interests of the Registrant, and (ii) in the case
of a criminal or administrative action or proceeding that is enforced by a
monetary penalty, such director or officer had reasonable grounds for believing
that his or her conduct was lawful.

         The By-laws of the Registrant provide that the Registrant shall
indemnify every director or officer of the Registrant, every former director or
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 or her heirs and legal representatives
to the extent permitted by YBCA.

         The Company maintains insurance for the benefit of its directors and
officers against liability in their respective capacities as directors and
officers that covers, among other things, U.S. SEC claims, subject to certain
corporate deductibles. The annual premium payable by the Company in respect of
such insurance is approximately $504,000. The directors and officers are not
required to pay any premium in respect of the insurance. The policy contains
standard industry exclusions and no claims have been made thereunder to date.

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


                                       2
<PAGE>

not previously disclosed in this Registration Statement or any material change
to such information in this 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 upon the
termination of the Certicom Corp. 1997 Stock Option Plan and the Certicom Corp.
Stock Option Plan.

          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 into this
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 1933
Act may be permitted to directors, officers or controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been informed that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
of 1933 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 Securities Act of
1933 and will be governed by the final adjudication of such issue.

Registrant or person who acts or acted at the Registrant's request as a director
or officer of another body corporate of which the Registrant is or was a

               incurred by him or her in respect of any civil, criminal or

               brought by or on behalf of the Registrant or body corporate to
               procure a judgment in its favor, to which he or she is made a
               party by reason of being or having been a director or officer
               of the Registrant or body corporate; and

         (c)   in respect of all costs, charges and expenses reasonably
               incurred by him or her in connection with the defense of any

               he or she is made a party by reason of having been a director
               or officer of the Registrant or body corporate, if he or she
               was substantially successful on the merits of his or her
               defense of the action or proceeding;

PROVIDED, in all cases, such director or officer (i) acted honestly and in good
faith with a view to the best interests of the Registrant, and (ii) in the case
of a criminal or administrative action or proceeding that is enforced by a
monetary penalty, such director or officer had reasonable grounds for believing
that his or her conduct was lawful.

         The By-laws of the Registrant provide that the Registrant shall
indemnify every director or officer of the Registrant, every former director or
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 or her heirs and legal representatives
to the extent permitted by YBCA.

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

                                       2
not previously disclosed in this Registration Statement or any material change
to such information in this 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 upon the
termination of the Certicom Corp. 1997 Stock Option Plan and the Certicom Corp.
Stock Option Plan.

          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 into this
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 1933
Act may be permitted to directors, officers or controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been informed that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
of 1933 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 Securities Act of
1933 and will be governed by the final adjudication of such issue.
