directors and officers against liabilities arising out of actions, suits and proceedings to which they are made or threatened to be made a party by reason of the fact that they have served or are currently serving as a director or officer to a
corporation. The indemnity may cover expenses (including attorneys&#146; fees) judgments, fines and amounts paid in settlement actually and reasonably incurred by the director or officer in connection with any such action, suit or proceeding.
Section&nbsp;145 permits corporations to pay expenses (including attorneys&#146; fees) incurred by directors and officers in advance of the final disposition of such action, suit or proceeding. In addition, Section&nbsp;145 provides that a
corporation has the power to purchase and maintain insurance on behalf of its directors and officers against any liability asserted against them and incurred by them in their capacity as a director or officer, or arising out of their status as such,
whether or not the corporation would have the power to indemnify the director or officer against such liability under Section&nbsp;145. </P>

Item 6. Indemnification of Directors and Officers.
Section 145 of the Delaware General Corporation Law (the "
DGCL
") authorizes a corporation to indemnify its
directors and officers against liabilities arising out of actions, suits and proceedings to which they are made or threatened to be made a party by reason of the fact that they have served or are currently serving as a director or officer to a
corporation. The indemnity may cover expenses (including attorneys' fees) judgments, fines and amounts paid in settlement actually and reasonably incurred by the director or officer in connection with any such action, suit or proceeding.
Section 145 permits corporations to pay expenses (including attorneys' fees) incurred by directors and officers in advance of the final disposition of such action, suit or proceeding. In addition, Section 145 provides that a
corporation has the power to purchase and maintain insurance on behalf of its directors and officers against any liability asserted against them and incurred by them in their capacity as a director or officer, or arising out of their status as such,
whether or not the corporation would have the power to indemnify the director or officer against such liability under Section 145.
The Registrant's restated certificate of incorporation and amended and restated bylaws contain provisions that limit or eliminate the
personal liability of the Registrant's directors and executive officers to the fullest extent permitted by the DGCL, as it now exists or may in the future be amended. Consequently, a director or executive officer will not be personally liable
to the Registrant or its stockholders for monetary damages or breach of fiduciary duty as a director, except for liability for:
•
any breach of the director's duty of loyalty to the Registrant or its stockholders;
•
any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;
•
any unlawful payments related to dividends or unlawful stock purchases, redemptions or other distributions; or
•
any transaction from which the director derived an improper personal benefit.
These
limitations of liability do not alter director liability under the federal securities laws and do not affect the availability of equitable remedies such as an injunction or rescission.
In addition, the Registrant's amended and restated bylaws provide that:
•
the Registrant will indemnify its directors and executive officers and, in the discretion of its board of directors, certain employees and agents to the fullest extent permitted by the DGCL, as it now exists or may in
the future be amended; and
•
the Registrant will advance reasonable expenses, including attorneys' fees, to its directors and executive officers, and in the discretion of its board of directors, to certain employees and agents, in connection
with legal proceedings relating to their service for or on behalf of the Registrant, subject to limited exceptions.
The
Registrant has entered into indemnification agreements with each of its directors and executive officers. These agreements provide that the Registrant will indemnify each of its directors, executive officers and, at times, their affiliates, to the
fullest extent permitted by the DGCL. The Registrant will advance expenses, including attorneys' fees (but excluding judgments, fines and settlement amounts), to each indemnified director, executive officer or affiliate in connection with any
proceeding in which indemnification is available and the Registrant will indemnify its directors and executive officers for any action or proceeding arising out of that person's services as a director or executive officer brought on behalf of
the Registrant and/or in furtherance of the Registrant's rights. Additionally, certain of the Registrant's directors may have certain rights to indemnification, advancement of expenses and/or insurance provided by their affiliates, which
indemnification relates to and might apply to the same proceedings arising out of such director's
2
services as a director referenced herein. Nonetheless, the Registrant has agreed in the indemnification agreements that the Registrant's obligations to those same directors are primary and
any obligation of the affiliates of those directors to advance expenses or to provide indemnification for the expenses or liabilities incurred by those directors are secondary.
The Registrant also maintains general liability insurance which covers certain liabilities of its directors and officers arising out of claims
based on acts or omissions in their capacities as directors or officers, including liabilities under the Securities Act.
Item 7. Exemption from
Registration Claimed.
Not applicable.
Item 8. Exhibits.
See the
Exhibit Index on the page immediately following the signature page for a list of exhibits filed as part of this Registration Statement, which Exhibit Index is incorporated herein by reference.
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 this 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 this
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 a 20 percent change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement;
(iii) To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or
any material change to such information in this 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 periodic 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 this 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.
(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.
3
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 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 may be permitted to directors, officers or controlling persons
of the Registrant pursuant to the indemnification provisions summarized in Item 6 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 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.
