ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Under the BUSINESS CORPORATIONS ACT (Ontario), the registrant may
indemnify a present or former director or officer or a person who acts or acted
at the registrant'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 of any civil, criminal or administrative action or proceeding to
which he is 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 criminal or administrative
action or proceeding that is enforced by a monetary penalty, had reasonable
grounds for believing that his conduct was lawful. Such indemnification may be
made in connection with a derivative action 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.

         In accordance with subsections 136(2) and (3) of the BUSINESS
CORPORATIONS ACT (Ontario), the by-laws of the registrant indemnify a director
or officer of the registrant, a 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 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 of any civil, criminal or administrative
action or proceeding to which he is made a party by reason of being or having
been a director or officer of the registrant of such corporation, if (i) he
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, he had reasonable grounds for
believing that his conduct was lawful.

         The directors and officers of the registrant are covered by directors'
and officers' insurance policies.

ITEM 9.           UNDERTAKINGS.

       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, as amended (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 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.

       4. The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act (and, where applicable, each
filing of an employee benefit plan's annual report pursuant to Section 15(d) of
the Exchange Act), each filing of the registrant's annual report pursuant to
Sections 13(a) or 15(d) of the Exchange Act that is incorporated by reference in
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.

       5. 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 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.

ITEM 4.  DESCRIPTION OF SECURITIES.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.
ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Under the BUSINESS CORPORATIONS ACT (Ontario), the registrant may
indemnify a present or former director or officer or a person who acts or acted
at the registrant'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 of any civil, criminal or administrative action or proceeding to
which he is 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 criminal or administrative
action or proceeding that is enforced by a monetary penalty, had reasonable
grounds for believing that his conduct was lawful. Such indemnification may be
made in connection with a derivative action 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.

         In accordance with subsections 136(2) and (3) of the BUSINESS
CORPORATIONS ACT (Ontario), the by-laws of the registrant indemnify a director
or officer of the registrant, a 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 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 of any civil, criminal or administrative
action or proceeding to which he is made a party by reason of being or having
been a director or officer of the registrant of such corporation, if (i) he
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, he had reasonable grounds for
believing that his conduct was lawful.

         The directors and officers of the registrant are covered by directors'
and officers' insurance policies.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED.

         Not applicable.

ITEM 8.  EXHIBITS.

         The following are filed as exhibits to this registration statement:
EXHIBITS          DESCRIPTION
4.1          Primetech Electronics Inc. Stock Option Plan
     5.1          Opinion of Davies Ward Phillips & Vineberg LLP
     23.1         Consent of Davies Ward Phillips & Vineberg LLP
                  Contained in such firm's opinion as filed as Exhibit 5.1 hereto
     23.2         Consent of Auditors
     24.1         Power of Attorney (included in signature page)
ITEM 9.           UNDERTAKINGS.

       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, as amended (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 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.

       4. The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act (and, where applicable, each
filing of an employee benefit plan's annual report pursuant to Section 15(d) of
the Exchange Act), each filing of the registrant's annual report pursuant to
Sections 13(a) or 15(d) of the Exchange Act that is incorporated by reference in
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.

       5. 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 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.

                                       3
