The right of directors and officers to indemnification, as set forth in the Certificate of Incorporation and Bylaws, also includes the right to be paid by the Registrant the expenses incurred in defending any such proceeding in advance of its final disposition.  Such a right to payments in advance is subject to such an individual&#8217;s undertaking to repay all such amounts if a court of competent jurisdiction ultimately determines by a final, non-appealable order that such director or officer is not entitled to be indemnified pursuant to the Certificate of Incorporation or Bylaws.</font></div><div style="line-height:120%;padding-bottom:6px;padding-top:16px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Section 145 of the Delaware General Corporation Law generally provides that a corporation may indemnify a director, officer, employee or agent of the corporation (or a person who is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise) against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person if he acted in good faith and in a manner he 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 his conduct was unlawful. In the case of an action brought by or in the right of a corporation, the corporation may indemnify a director, officer, employee or agent of the corporation (or a person who is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise) against expenses (including attorneys' fees) actually and reasonably incurred by him if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification may be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent a court finds that, in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses as the court shall deem proper.</font></div><div style="line-height:120%;padding-bottom:6px;padding-top:16px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Registrant's Certificate of Incorporation and Bylaws further provide that the Registrant may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Registrant or another corporation, partnership, joint venture, trust, or other enterprise against any such expense, liability, or loss whether or not the Registrant would have the power to indemnify such person against such expense, liability, or loss under the Delaware General Corporate Law.</font></div><div style="line-height:120%;padding-bottom:6px;padding-top:16px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Registrant maintains an officer's and director's liability insurance policy insuring its officers and directors against certain expenses, liabilities, and losses incurred by them in their capacities as such, and insuring the Registrant under certain circumstances, in the event that indemnification payments are made to such officers and directors.</font></div><div style="line-height:120%;padding-bottom:6px;padding-top:16px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Registrant has also entered into indemnification agreements (the &#8220;Indemnification Agreements&#8221;) with certain of its directors and officers (individually, the &#8220;Indemnitee&#8221;). The Indemnification Agreements require the Registrant, among other things, to indemnify the Indemnitee against specified expenses and liabilities, such as attorneys&#8217; fees, judgments, fines and settlements, reasonably incurred or suffered by the individual in connection with any action, suit or proceeding by reason of the fact that the individual was a director or officer of the Company where the Indemnitee was or is made, or threatened to be made, a party to, or involved as a party, witness or otherwise, and to advance expenses incurred by the individual in connection therewith; provided however, that the Registrant shall indemnify Indemnitee in connection with a proceeding (or part thereof) initiated by Indemnitee only if such proceeding (or part thereof) was authorized by the board of directors of the Registrant. The Indemnification Agreements provide for the advancement of all expenses to the Indemnitee upon the Registrant&#8217;s receipt from or on behalf of Indemnitee of reasonable evidence of such expenses, together with a written undertaking by Indemnitee to repay all amounts so advanced if it shall ultimately be determined by a final, nonappealable order of a court of competent jurisdiction that Indemnitee is not entitled to be indemnified under the Indemnification Agreement. Accordingly, if such ultimate determination is made, the Registrant shall be entitled to reimbursement by Indemnitee of any amounts paid in advance toward such indemnification.</font></div><div

The Registrant's Certificate of Incorporation and Bylaws provide that the Registrant shall indemnify to the full extent authorized or permitted by the Delaware General Corporate Law (as the same exists or hereafter amended) any person made, or threatened to be made, a party to, or is involved in any action, suit or proceeding (whether civil, criminal, administrative, or investigative) by reason of the fact that he or she is or was a director or officer of the Registrant or is or was serving at the request of the Company as a director, officer, employee, or agent of another corporation or of a partnership, joint venture, trust, or other enterprise, including service with respect to employee benefit plans, or in any other capacity.  The right of directors and officers to indemnification, as set forth in the Certificate of Incorporation and Bylaws, also includes the right to be paid by the Registrant the expenses incurred in defending any such proceeding in advance of its final disposition.  Such a right to payments in advance is subject to such an individual's undertaking to repay all such amounts if a court of competent jurisdiction ultimately determines by a final, non-appealable order that such director or officer is not entitled to be indemnified pursuant to the Certificate of Incorporation or Bylaws.
Section 145 of the Delaware General Corporation Law generally provides that a corporation may indemnify a director, officer, employee or agent of the corporation (or a person who is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise) against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person if he acted in good faith and in a manner he 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 his conduct was unlawful. In the case of an action brought by or in the right of a corporation, the corporation may indemnify a director, officer, employee or agent of the corporation (or a person who is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise) against expenses (including attorneys' fees) actually and reasonably incurred by him if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification may be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent a court finds that, in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses as the court shall deem proper.
The Registrant's Certificate of Incorporation and Bylaws further provide that the Registrant may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Registrant or another corporation, partnership, joint venture, trust, or other enterprise against any such expense, liability, or loss whether or not the Registrant would have the power to indemnify such person against such expense, liability, or loss under the Delaware General Corporate Law.
The Registrant maintains an officer's and director's liability insurance policy insuring its officers and directors against certain expenses, liabilities, and losses incurred by them in their capacities as such, and insuring the Registrant under certain circumstances, in the event that indemnification payments are made to such officers and directors.
The Registrant has also entered into indemnification agreements (the "Indemnification Agreements") with certain of its directors and officers (individually, the "Indemnitee"). The Indemnification Agreements require the Registrant, among other things, to indemnify the Indemnitee against specified expenses and liabilities, such as attorneys' fees, judgments, fines and settlements, reasonably incurred or suffered by the individual in connection with any action, suit or proceeding by reason of the fact that the individual was a director or officer of the Company where the Indemnitee was or is made, or threatened to be made, a party to, or involved as a party, witness or otherwise, and to advance expenses incurred by the individual in connection therewith; provided however, that the Registrant shall indemnify Indemnitee in connection with a proceeding (or part thereof) initiated by Indemnitee only if such proceeding (or part thereof) was authorized by the board of directors of the Registrant. The Indemnification Agreements provide for the advancement of all expenses to the Indemnitee upon the Registrant's receipt from or on behalf of Indemnitee of reasonable evidence of such expenses, together with a written undertaking by Indemnitee to repay all amounts so advanced if it shall ultimately be determined by a final, nonappealable order of a court of competent jurisdiction that Indemnitee is not entitled to be indemnified under the Indemnification Agreement. Accordingly, if such ultimate determination is made, the Registrant shall be entitled to reimbursement by Indemnitee of any amounts paid in advance toward such indemnification.
The foregoing summaries are necessarily subject to the complete text of the statute, the Registrant's Certificate of Incorporation and Bylaws, and the arrangements referred to above and are qualified in their entirety by reference thereto.

Item 9.        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;
(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.  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 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and
(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;
p
rovided, 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 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, 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; and
(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 Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant'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 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 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 Commission 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.
