Bylaws, as amended, provides for indemnification of officers, directors, agents and employees of the Company generally consistent with the provisions of Section&nbsp;145 of the Delaware General Corporation Law. Pursuant to Section&nbsp;145 of the
Delaware General Corporation Law, a corporation generally has the power to indemnify its present and former directors, officers, employees and agents against expenses incurred by them in connection with any suit to which they are, or are threatened
to be made, a party by reason of their serving in such positions so long as they acted in good faith and in a manner they reasonably believed to be in, or not opposed to, the best interests of the corporation, and with respect to any criminal
action, they had no reasonable cause to believe their conduct was unlawful. With respect to suits by or in the right of a corporation, however, indemnification is not available if such person is adjudged to be liable for negligence or misconduct in
the performance of his or her duty to the corporation unless the court determines that indemnification is appropriate. In addition, a corporation has the power to purchase and maintain insurance for such persons. The statute also expressly provides
that the power to indemnify authorized thereby is not exclusive of any rights granted under any bylaw, agreement, vote of stockholders or disinterested directors, or otherwise. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">As permitted by Section&nbsp;102 of the Delaware General Corporation Law, the Company&#146;s stockholders have approved and incorporated
provisions into the Company&#146;s Restated Certificate of Incorporation eliminating a director&#146;s personal liability for monetary damages to the Company and the Company&#146;s stockholders arising from a breach of a director&#146;s fiduciary
duty, except for liability under Section&nbsp;174 of the Delaware General Corporation Law or liability for any breach of the director&#146;s duty of loyalty to the Company or the Company&#146;s stockholders, for acts or omissions not in good faith
or that involve intentional misconduct or a knowing violation of law or for any transaction in which the director derived an improper personal benefit. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Company has entered into indemnification agreements with the Company&#146;s directors and officers. These agreements provide broader
indemnity rights than those provided under the Delaware General Corporation Law and the Company&#146;s Bylaws. The indemnification agreements are not intended to deny or otherwise limit third party or derivative suits against the Company or the
Company&#146;s directors or officers, but to the extent a director or officer were entitled to indemnity or contribution under the indemnification agreement, the financial burden of a third party suit would be borne by the Company, and the Company
would not benefit from derivative recoveries against the director or officer. Such recoveries would accrue to the benefit of the Company but would be offset by the Company&#146;s obligations to the director or officer under the indemnification
agreement. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The above discussion of the Company&#146;s Bylaws, Restated Certificate of Incorporation and of Section&nbsp;145 of the

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. </P>
