    <div><br>
    </div>
    <div style="text-align: justify;">The Company&#8217;s Constitution provides for indemnification of the Company&#8217;s officers and directors to the full extent permitted by applicable law.</div>
    <div><br>
    </div>
    <div style="text-align: justify;">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&#8217;s Constitution. The indemnification agreements require the Company, among other things, to indemnify such persons against expenses, including attorneys&#8217; 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&#8217;s right, that may arise by reason of their status or service as the Company&#8217;s director or executive officer and to advance expenses incurred by them in connection
      with any such proceedings.</div>
    <div><br>
    </div>
    <div style="text-align: justify;">Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the Company pursuant to the foregoing provisions, the Company 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 and is theretofore unenforceable.</div>

    <div><br>
    </div>
    <div style="text-align: justify; text-indent: 36pt; color: #000000;">(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:</div>
    <div><br>
    </div>
    <div style="text-align: justify; text-indent: 36pt; color: #000000;">(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;</div>
    <div><br>
    </div>
    <div style="text-align: justify; text-indent: 36pt; color: #000000;">(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 &#8220;Calculation of Registration Fee&#8221; table in the effective registration statement;</div>
    <div><br>
    </div>
    <div style="text-align: justify; text-indent: 36pt; color: #000000;">(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;</div>
    <div><br>
    </div>
    <div style="text-align: justify; color: #000000;"><font style="font-style: italic;">Provided, however,</font> that paragraphs (A)(1)(i) and (A)(1)(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.</div>
    <div><br>
    </div>
    <div style="text-align: justify; text-indent: 36pt; color: #000000;">(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.</div>
    <div><br>
    </div>
    <div style="text-align: justify; text-indent: 36pt; color: #000000;">(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.</div>
    <div><br>
    </div>
    <div style="text-align: justify; text-indent: 36pt; color: #000000;">B. The undersigned Company hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Company&#8217;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&#8217;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.</div>
    <div><br>
    </div>
    <div style="text-align: justify; text-indent: 36pt; color: #000000;">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.</div>

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.
Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the Company pursuant to the foregoing provisions, the Company 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 and is theretofore unenforceable.

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)(1)(i) and (A)(1)(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.
