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 has agreed to advance expenses, including attorneys&#146; 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&#146;s services as a director or executive officer brought on behalf of the Registrant and/or in furtherance of its rights. Additionally, certain of the Registrant&#146;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&#146;s services as a director referenced herein.
Nonetheless, the Registrant has agreed in the indemnification agreements that the Registrant&#146;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. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Registrant also maintains general

the opinion of 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>

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 of the DGCL 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 of the DGCL 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 of the DGCL.
The Registrant has adopted provisions in the Registrant's certificate of incorporation and bylaws 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 of the Registrant 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 or executive officer'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;
II-1
Table of Contents
•
any unlawful payments related to dividends or unlawful stock purchases, redemptions or other distributions; or
•
any transaction from which the director or executive officer 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 bylaws provide that:
•
the Registrant will indemnify the Registrant's directors and executive officers and, in the discretion of our 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 the Registrant's directors and executive officers, and, in the discretion of Registrant's 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 has agreed to 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 its 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 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 the Registrant's 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.

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

(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

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 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 the Registration Statement or any material change to such information in the Registration Statement;
provided
,
however
, thatclauses (a)(1)(i) and (a)(1)(ii) above 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 Exchange Act 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.
(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 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.
