STYLE="font-family:Times New Roman" SIZE="2">Pursuant to Section&nbsp;102 of the General Corporation Law of Delaware, the Corporation has adopted a provision in its Certificate of Incorporation eliminating the personal liability of its directors for
monetary damages to the Corporation and its stockholders for any breach of their fiduciary duties as directors of the Corporation, except for their liability due to (1)&nbsp;breach of loyalty to the Corporation, (2)&nbsp;acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of law, (3)&nbsp;any transaction from which the director derived an improper personal benefit or (4)&nbsp;any payment of unlawful dividends or an unlawful stock repurchase or
redemption. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Section&nbsp;145 of the Delaware General Corporation Law permits a Delaware corporation to indemnify any person
who is or was a party to any actual or threatened legal action, whether criminal, civil, administrative or investigative, because of his or her service as an officer, director or agent of the Corporation against expenses, judgments, fines and
settlement payments actually and reasonably incurred by him or her in connection with such proceeding, if he or she 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 action or proceeding, had no reasonable cause to believe was unlawful, except that, (i)&nbsp;to the extent a present or former director or officer has been successful on the merits or otherwise in the legal action,
indemnification for expenses actually and reasonably incurred is mandatory and (ii)&nbsp;with respect to any legal action by or in the right of the Corporation itself, an officer, director or agent of the Corporation is not entitled to
indemnification if adjudged liable to the Corporation, except for expenses actually and reasonably incurred if approved by the court. Section&nbsp;6.5 of the Corporation&#146;s Bylaws provides that the Corporation is required to indemnify officers,
directors, employees, fiduciaries and agents (and their heirs and legal representatives) of the Corporation or any constituent corporation absorbed in a consolidation or merger or of a subsidiary of the Corporation, or persons who serve as such with
another corporation, partnership, joint venture, trust or other enterprise at the request of the Corporation or any such constituent corporation or subsidiary, to the full extent permitted by Delaware law. The Corporation maintains insurance
coverage for the purpose of providing indemnification benefits in certain circumstances. </FONT></P> <P STYLE="font-size:18px;margin-top:0px;margin-bottom:0px">&nbsp;</P>
