<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Company is incorporated under the Delaware General Corporation Law (the &#147;DGCL&#148;). </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Section&nbsp;145(a) of the DGCL provides that a Delaware corporation shall have the power to indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the
person is or was a director, officer, employee or agent of the corporation, or 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&#146; fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in
a manner the person 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 the person&#146;s conduct was unlawful. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Section&nbsp;145(b) of the DGCL provides that a Delaware corporation shall have the power to indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that such person acted in any of the capacities set forth above,
against expenses (including attorneys&#146; fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted under standards similar to those discussed above, except that no
indemnification shall 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 that the Court of Chancery or the court in which such action or
suit was brought shall determine that despite the adjudication of liability, such person is fairly and reasonably entitled to be indemnified for such expenses which the Court of Chancery or such other court shall deem proper. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Section&nbsp;145 of the DGCL further provides that to the extent a current or former director or officer of a corporation has been successful
on the merits or otherwise in defense of any action, suit or proceeding referred to in subsections (a)&nbsp;and (b)&nbsp;or in the defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including
attorneys&#146; fees) actually and reasonably incurred by such person in connection therewith; and that indemnification provided for by Section&nbsp;145 shall not be deemed exclusive of any other rights to which the indemnified party may be
entitled; and that the corporation shall have power to purchase and maintain insurance on behalf of a director or officer of the corporation against any liability asserted against such person and incurred by such person in any such capacity or
arising out of such person&#146;s status as such whether or not the corporation would have the power to indemnify such person against such liability under Section&nbsp;145. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Section&nbsp;102(b)(7) of the DGCL provides that a corporation may eliminate or limit the personal liability of a director or officer to the
corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, provided that such provisions shall not eliminate or limit the liability of (1)&nbsp;a director for any breach of the director&#146;s duty of
loyalty to the corporation or its stockholders, (2)&nbsp;a director for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (3)&nbsp;a director under section 174 of the DGCL; (4)&nbsp;for any
transaction from which the director derived an improper personal benefit; or (5)&nbsp;an officer in any action by or in the right of the corporation. No such provision shall eliminate or limit the liability of a director for any act or omission
occurring before the date when such provision becomes effective. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Article Seven of the Company&#146;s Amended and Restated <FONT

<FONT STYLE="white-space:nowrap">By-laws</FONT> provides that the Company shall indemnify any person in connection with any action, suit or proceeding brought or threatened by reason of the fact that he or she is or was one of the Company&#146;s
directors, officers, employees or agents, or is or was serving at the Company&#146;s request as a director, officer, employee or agent of another enterprise, against all costs actually and reasonably incurred by him or her in connection with such
action, suit or 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 Company&#146;s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to
believe his or her conduct was unlawful. Similar indemnity is permitted to be provided to such persons in connection with an action or suit by the Company or in the Company&#146;s right, and provided further that such person shall not have been
adjudged liable for negligence or misconduct in the performance of his or her duty to the Company, unless, in view of all the circumstances of the case, the court in which the action or suit was brought determines that such person despite the
adjudication of liability is fairly and reasonably entitled to indemnity for such expenses. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Article Twelve of the Company&#146;s Amended
and Restated Certificate of Incorporation eliminates the liability of the Company&#146;s directors for monetary damages for breach of fiduciary duty as a director except where a director breaches his or her duty of loyalty to the Company and its
stockholders, fails to act in good faith or engages in intentional misconduct or a knowing violation of law, authorizes the payment of a dividend or stock repurchase that is illegal under Section&nbsp;174 of the DGCL, or obtains 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 also maintains and pays premiums on a directors&#146; and officers&#146; liability insurance policy and has entered
into indemnity agreements with its directors and officers. The provisions of each indemnity agreement alter or clarify the statutory indemnification in the following respects: (1)&nbsp;indemnity will be explicitly provided for settlements in
derivative actions; (2)&nbsp;prompt payment of litigation expenses will be provided in advance of indemnification; (3)&nbsp;prompt indemnification of advances of expenses will be provided unless a determination is made that the director or officer
has not met the required standard; (4)&nbsp;the director or officer will be permitted to petition a court to determine whether his or her actions meet the standards required; and (5)&nbsp;partial indemnification will be permitted in the event that
the director or officer is not entitled to full indemnification. In addition, each indemnity agreement specifically includes indemnification with respect to actions, suits or proceedings brought under and/or predicated upon the Securities Act of
1933, as amended, and/or the Securities Exchange Act of 1934, as amended. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The preceding summary is qualified in its entirety by the

<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:9%; font-size:10pt; font-family:Times New Roman">(i) To include any prospectus required by Section&nbsp;10(a)(3) of the Securities Act of 1933; </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:9%; font-size:10pt; font-family:Times New Roman">(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 SEC
pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20&nbsp;percent change in the maximum aggregate offering price set forth in the &#147;Calculation of Registration Fee&#148; table in the effective

paragraphs (a)(1)(i) and (a)(1)(ii) of this section 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 SEC by the registrant pursuant to
Section&nbsp;13 or Section&nbsp;15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">(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 offered therein, and the offering of such securities at that time shall be deemed to be the initial <I>bona fide</I> offering thereof. </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">(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. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of

Section&nbsp;15(d)&nbsp;of the Securities Exchange Act of 1934) that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such

the Securities Act of 1933 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 Securities Act of 1933 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. </P>

Item 4. Description of Securities.
Not applicable.
Item 5. Interests of
Named Expert and Counsel.
Not applicable.
Item 6. Indemnification of Directors and Officers.
The Company is incorporated under the Delaware General Corporation Law (the "DGCL").
Section 145(a) of the DGCL provides that a Delaware corporation shall have the power to indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the
person is or was a director, officer, employee or agent of the corporation, or 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 in connection with such action, suit or proceeding if the person acted in good faith and in
a manner the person 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 the person's conduct was unlawful.
Section 145(b) of the DGCL provides that a Delaware corporation shall have the power to indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that such person acted in any of the capacities set forth above,
against expenses (including attorneys' fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted under standards similar to those discussed above, except that no
indemnification shall 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 that the Court of Chancery or the court in which such action or
suit was brought shall determine that despite the adjudication of liability, such person is fairly and reasonably entitled to be indemnified for such expenses which the Court of Chancery or such other court shall deem proper.
Section 145 of the DGCL further provides that to the extent a current or former director or officer of a corporation has been successful
on the merits or otherwise in defense of any action, suit or proceeding referred to in subsections (a) and (b) or in the defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by such person in connection therewith; and that indemnification provided for by Section 145 shall not be deemed exclusive of any other rights to which the indemnified party may be
entitled; and that the corporation shall have power to purchase and maintain insurance on behalf of a director or officer of the corporation against any liability asserted against such person and incurred by such person in any such capacity or
arising out of such person's status as such whether or not the corporation would have the power to indemnify such person against such liability under Section 145.
Section 102(b)(7) of the DGCL provides that a corporation may eliminate or limit the personal liability of a director or officer to the
corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, provided that such provisions shall not eliminate or limit the liability of (1) a director for any breach of the director's duty of
loyalty to the corporation or its stockholders, (2) a director for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (3) a director under section 174 of the DGCL; (4) for any
transaction from which the director derived an improper personal benefit; or (5) an officer in any action by or in the right of the corporation. No such provision shall eliminate or limit the liability of a director for any act or omission
occurring before the date when such provision becomes effective.
Article Seven of the Company's Amended and Restated
By-laws
and Article Twelve of the Company's Amended and Restated Certificate of Incorporation provide for the indemnification of each of the Company's directors, officers, employees or agents to the full
extent permitted by the DGCL or other applicable laws presently or hereafter in effect.
Article Seven of the Company's Amended and Restated
By-laws
provides that the Company shall indemnify any person in connection with any action, suit or proceeding brought or threatened by reason of the fact that he or she is or was one of the Company's
directors, officers, employees or agents, or is or was serving at the Company's request as a director, officer, employee or agent of another enterprise, against all costs actually and reasonably incurred by him or her in connection with such
action, suit or 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 Company's best interests and, with respect to any criminal action or proceeding, had no reasonable cause to
believe his or her conduct was unlawful. Similar indemnity is permitted to be provided to such persons in connection with an action or suit by the Company or in the Company's right, and provided further that such person shall not have been
adjudged liable for negligence or misconduct in the performance of his or her duty to the Company, unless, in view of all the circumstances of the case, the court in which the action or suit was brought determines that such person despite the
adjudication of liability is fairly and reasonably entitled to indemnity for such expenses.
Article Twelve of the Company's Amended
and Restated Certificate of Incorporation eliminates the liability of the Company's directors for monetary damages for breach of fiduciary duty as a director except where a director breaches his or her duty of loyalty to the Company and its
stockholders, fails to act in good faith or engages in intentional misconduct or a knowing violation of law, authorizes the payment of a dividend or stock repurchase that is illegal under Section 174 of the DGCL, or obtains an improper personal
benefit.
The Company also maintains and pays premiums on a directors' and officers' liability insurance policy and has entered
into indemnity agreements with its directors and officers. The provisions of each indemnity agreement alter or clarify the statutory indemnification in the following respects: (1) indemnity will be explicitly provided for settlements in
derivative actions; (2) prompt payment of litigation expenses will be provided in advance of indemnification; (3) prompt indemnification of advances of expenses will be provided unless a determination is made that the director or officer
has not met the required standard; (4) the director or officer will be permitted to petition a court to determine whether his or her actions meet the standards required; and (5) partial indemnification will be permitted in the event that
the director or officer is not entitled to full indemnification. In addition, each indemnity agreement specifically includes indemnification with respect to actions, suits or proceedings brought under and/or predicated upon the Securities Act of
1933, as amended, and/or the Securities Exchange Act of 1934, as amended.
The preceding summary is qualified in its entirety by the
Company's Amended and Restated Certificate of Incorporation and Amended and Restated
By-laws,
and the indemnity agreements described above.

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 of 1933;
(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 SEC
pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent 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;
Provided, however
, that
paragraphs (a)(1)(i) and (a)(1)(ii) of this section 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 SEC 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 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, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in this 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 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 Securities Act of 1933 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.
