plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this Registration Statement shall

as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of
the Company pursuant to the foregoing provisions, or otherwise, the Company 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 Company of expenses incurred or paid by a director, officer
or controlling person of the Company 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 Company 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 Securities Act and will be governed by the final adjudication of such issue.</P>

"Commission") are incorporated into this Registration Statement by reference, as of their respective dates:
(1)       The
Company's annual report on Form 20-F for the year ended June 30, 2022, filed with the Commission on September 13, 2022, which contains

report filed for the purpose of updating such description.
All documents subsequently filed by the Company
pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act subsequent to the date of this Registration Statement and prior to
the filing of a post-effective amendment to this Registration Statement which indicates that all securities then remaining unsold shall
be deregistered, including any reports of foreign private issuers on Form 6-K submitted during such period (or portion thereof) that is
identified in such form as being incorporated by reference into this Registration Statement, shall be deemed to be incorporated by reference
in this Registration Statement and to be a part hereof from the date of the filing of such documents. The Company is not incorporating
by reference any documents or portions thereof, whether specifically listed above or filed in the future, that are not deemed "filed"
with the Commission.
For purposes of this Registration Statement and
the related prospectus, any statement contained in a document incorporated or deemed to be incorporated by reference shall be deemed to
be modified or superseded to the extent that a statement contained herein or in a subsequently filed document which also is or is deemed
to be incorporated herein by reference modifies or replaces such statement. Any statement so modified shall not be deemed in its unmodified
form to constitute part of this Registration Statement or the related prospectus.
Item 4. Description of Securities.
Not applicable.
Item 5. Interests of Named Experts and Counsel.
Not applicable.
Item 6. Indemnification of Directors and Officers.
The Company's Constitution provides for indemnification
of the Company's officers and directors to the full extent permitted by applicable law.
In addition, the Company has entered into agreements
to indemnify its directors and executive officers containing provisions, which are in some respects broader than the specific indemnification
provisions contained in the Company's Constitution. The indemnification agreements require the Company, among other things, to indemnify
such persons against expenses, including attorneys' fees, judgments, liabilities, fines and settlement amounts incurred by any such person
in actions or proceedings, including actions by the Company or in the Company's right, that may arise by reason of their status or service
as the Company's director or executive officer and to advance expenses incurred by them in connection with any such proceedings.

Item 9. Undertakings.
A.        The
Company 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 this 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 this 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 end 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 changes in volume
and price represent no more than a 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 this Registration Statement or any
material change to such information in this Registration Statement;
Provided
,
however
, that paragraphs (A)(l)(i) and (A)(l)(ii)
shall not apply if the registration statement is on Form S-8, 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 Company 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.
(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 Company hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Company'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 this Registration Statement shall
be deemed to be a new registration statement relating to the securities offered herein, 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 Company pursuant to the foregoing provisions, or otherwise, the Company 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 Company of expenses incurred or paid by a director, officer
or controlling person of the Company 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 Company 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 Securities Act and will be governed by the final adjudication of such issue.
