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&#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>

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 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 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 in limited circumstances.
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 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 or will enter into indemnification agreements with each of its directors, executive officers and certain other officers. These agreements provide that the Registrant will indemnify each of its directors, executive officers, certain
other officers and, at times, their affiliates, to the fullest extent permitted by the DGCL.
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 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 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 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
, that paragraphs (a)(1)(i) and (a)(1)(ii)
of this section shall 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 Securities and Exchange 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.
