  <div style="text-indent: 36pt;">Chapter 17, Subchapter D of the Pennsylvania Business Corporation Law of 1988, as amended, or the PBCL, contains provisions permitting indemnification of officers and directors of a business corporation incorporated in
    Pennsylvania. Sections 1741 and 1742 of the PBCL provide that a business corporation may indemnify directors and officers against liabilities and expenses they may incur as such in connection with any threatened, pending or completed civil,
    administrative or investigative proceeding, provided that the particular person acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to any criminal
    proceeding, had no reasonable cause to believe his or her conduct was unlawful. In general, the power to indemnify under these sections does not exist in the case of actions against a director or officer by or in the right of the corporation if the
    person otherwise entitled to indemnification shall have been adjudged to be liable to the corporation unless it is judicially determined that, despite the adjudication of liability but in view of all the circumstances of the case, the person is fairly
    and</div>

  <div>reasonably entitled to indemnification for specified expenses. Section 1743 of the PBCL provides that the corporation is required to indemnify directors and officers against expenses they may incur in defending actions against them in such
    capacities if they are successful on the merits or otherwise in the defense of such actions.</div>
  <div><br>
  </div>
  <div style="text-indent: 36pt;">Section 1746 of the PBCL grants a corporation broad authority to indemnify its directors and officers for liabilities and expenses incurred in such capacity, except in circumstances where the act or failure to act giving
    rise to the claim for indemnification is determined by a court to have constituted willful misconduct or recklessness.</div>
  <div><br>
  </div>
  <div style="text-indent: 36pt;">Section 1747 of the PBCL permits a corporation to purchase and maintain insurance on behalf of any person who is or was a director or officer of the corporation, or is or was serving at the request of the corporation as a
    representative of another corporation or other enterprise, against any liability asserted against such person and incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not the corporation would have the
    power to indemnify the person against such liability under Chapter 17, Subchapter D of the PBCL.</div>
  <div><br>
  </div>
  <div style="text-indent: 36pt;">Section 3.01(b) of the Registrant&#8217;s Bylaws provides that a director shall not be personally liable for monetary damages for any action taken, or any failure to take any action, unless the director has breached or failed to
    perform the duties of his or her office and the breach or failure to perform constitutes self-dealing, willful misconduct or recklessness. These provisions do not apply to the responsibility or liability of a director pursuant to any criminal statute
    or the liability of a director for the payment of taxes pursuant to local, state or federal law.</div>
  <div><br>
  </div>
  <div style="text-indent: 36pt;">Section 7.01 of the Registrant&#8217;s Bylaws provides that the Registrant shall indemnify directors and officers against any liability incurred in connection with any proceeding in which the director or officer may be involved
    by reason of the fact that such person was serving in an indemnified capacity, including without limitation liabilities resulting from any actual or alleged breach or neglect of duty, error, misstatement or misleading statement, negligence, gross
    negligence or act giving rise to strict products liability, except where such indemnification is expressly prohibited by applicable law or where the conduct has been determined to constitute willful misconduct or recklessness.</div>
  <div><br>
  </div>
  <div style="text-indent: 36pt;">Section 7.04 of the Registrant&#8217;s Bylaws provides that the Registrant may maintain insurance or use any other arrangement to satisfy or secure its indemnification obligations. The Registrant has an insurance policy which
    insures its directors and officers against certain liabilities which might be incurred in connection with the performance of their duties.</div>

Item 6.
Indemnification of Directors and Officers.
Chapter 17, Subchapter D of the Pennsylvania Business Corporation Law of 1988, as amended, or the PBCL, contains provisions permitting indemnification of officers and directors of a business corporation incorporated in
    Pennsylvania. Sections 1741 and 1742 of the PBCL provide that a business corporation may indemnify directors and officers against liabilities and expenses they may incur as such in connection with any threatened, pending or completed civil,
    administrative or investigative proceeding, provided that the particular person acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to any criminal
    proceeding, had no reasonable cause to believe his or her conduct was unlawful. In general, the power to indemnify under these sections does not exist in the case of actions against a director or officer by or in the right of the corporation if the
    person otherwise entitled to indemnification shall have been adjudged to be liable to the corporation unless it is judicially determined that, despite the adjudication of liability but in view of all the circumstances of the case, the person is fairly
    and
- 3 -
reasonably entitled to indemnification for specified expenses. Section 1743 of the PBCL provides that the corporation is required to indemnify directors and officers against expenses they may incur in defending actions against them in such
    capacities if they are successful on the merits or otherwise in the defense of such actions.
Section 1746 of the PBCL grants a corporation broad authority to indemnify its directors and officers for liabilities and expenses incurred in such capacity, except in circumstances where the act or failure to act giving
    rise to the claim for indemnification is determined by a court to have constituted willful misconduct or recklessness.
Section 1747 of the PBCL permits a corporation to purchase and maintain insurance on behalf of any person who is or was a director or officer of the corporation, or is or was serving at the request of the corporation as a
    representative of another corporation or other enterprise, against any liability asserted against such person and incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not the corporation would have the
    power to indemnify the person against such liability under Chapter 17, Subchapter D of the PBCL.
Section 3.01(b) of the Registrant's Bylaws provides that a director shall not be personally liable for monetary damages for any action taken, or any failure to take any action, unless the director has breached or failed to
    perform the duties of his or her office and the breach or failure to perform constitutes self-dealing, willful misconduct or recklessness. These provisions do not apply to the responsibility or liability of a director pursuant to any criminal statute
    or the liability of a director for the payment of taxes pursuant to local, state or federal law.
Section 7.01 of the Registrant's Bylaws provides that the Registrant shall indemnify directors and officers against any liability incurred in connection with any proceeding in which the director or officer may be involved
    by reason of the fact that such person was serving in an indemnified capacity, including without limitation liabilities resulting from any actual or alleged breach or neglect of duty, error, misstatement or misleading statement, negligence, gross
    negligence or act giving rise to strict products liability, except where such indemnification is expressly prohibited by applicable law or where the conduct has been determined to constitute willful misconduct or recklessness.
Section 7.04 of the Registrant's Bylaws provides that the Registrant may maintain insurance or use any other arrangement to satisfy or secure its indemnification obligations. The Registrant has an insurance policy which
    insures its directors and officers against certain liabilities which might be incurred in connection with the performance of their duties.

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:
(i)
To include any prospectus required by section 10(a)(3) of the Securities Act of 1933, as amended;
(ii)
To reflect in the prospectus any facts or events arising after the effective date of the 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 the registration statement;
(iii)
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;
provided
,
however
, that Paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or
    furnished to the Securities and Exchange Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the 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
- 5 -
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 that remain unsold at the termination of the offering.
(b)
The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, as amended, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
            Exchange Act of 1934, as amended, 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 of 1933, as amended, 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 SEC such indemnification is against public policy as expressed in the 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 Act and will be governed by the final adjudication of such issue.
