Delaware General Corporation Law provides that a Delaware corporation may indemnify any person who
is, 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 such corporation), by reason of the fact that such person is or was an officer, director,
employee or agent of such corporation, or is or was serving at the request of such corporation as an
officer, director, employee or agent of another corporation or enterprise. The indemnity may
include expenses (including attorneys&#146; fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by such person in connection with such action, suit or proceeding,
provided that such person acted in good faith and in a manner he or she reasonably believed to be

by or in the right of the corporation by reason of the fact that such person is or was a director,
officer, employee or agent of such corporation, or is or was serving at the request of such

director is successful on the merits or otherwise in the defense of any action referred to above,
the corporation must indemnify him or her against the expenses that he or she has
actually and reasonably incurred. The Registrant&#146;s amended and restated certificate of

indemnification agreements with its directors and executive officers, in addition to
indemnification provided for in the Registrant&#146;s bylaws, and intends to enter into indemnification
agreements with any new directors and executive officers in the future. Under these agreements, the
Registrant is required to indemnify such executive officers and directors against all expenses
(including attorneys&#146; fees), witness fees, judgments, fines, settlements and other amounts incurred in connection
with any action, suit or proceeding, or alternative dispute mechanism, inquiry, hearing or investigation, whether actual or threatened, to which any such person may be
made a party by reason of the fact that such person is or was a director, officer, stockholder, controlling person, agent or employee of
the Registrant or any of its affiliated enterprises. The Registrant&#146;s obligation to pay these
amounts is subject to the condition that it is not finally determined that any such person would not be permitted to be indemnified under applicable law. The
indemnification agreements also set forth procedures that will apply in the event of a claim for
indemnification thereunder.

    <TD>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
Securities and Exchange 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.</TD>

DESCRIPTION OF SECURITIES

INTERESTS OF NAMED EXPERTS AND COUNSEL
Not applicable.
INDEMNIFICATION OF DIRECTORS AND OFFICERS
The Registrant is incorporated under the laws of the State of Delaware. Section 145 of the
Delaware General Corporation Law provides that a Delaware corporation may indemnify any person who
is, 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 such corporation), by reason of the fact that such person is or was an officer, director,
employee or agent of such corporation, or is or was serving at the request of such corporation as an
officer, director, employee or agent of another corporation or enterprise. The indemnity may
include expenses (including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by such person in connection with such action, suit or proceeding,
provided that such person acted in good faith and in a manner he or she reasonably believed to be
in or not opposed to the corporation's best
3
interests and, with respect to any criminal action or proceeding, had no reasonable cause to
believe that his or her conduct was illegal. A Delaware corporation may indemnify any person who
is, 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 by reason of the fact that such person is or was a director,
officer, employee or agent of such corporation, or is or was serving at the request of such
corporation as a director, officer, employee or agent of another corporation or enterprise. The
indemnity may include expenses (including attorneys' fees) actually and reasonably incurred by such
person in connection with the defense or settlement of such action or suit provided such person
acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the
corporation's best interests except that no indemnification is permitted without judicial approval
if the officer or director is adjudged to be liable to the corporation. Where a present or former officer or
director is successful on the merits or otherwise in the defense of any action referred to above,
the corporation must indemnify him or her against the expenses that he or she has
actually and reasonably incurred. The Registrant's amended and restated certificate of
incorporation and bylaws provide for the indemnification of the Registrant's directors and officers
to the fullest extent permitted under the Delaware General Corporation Law.
The Registrant's amended and restated certificate of incorporation contains a provision
permitted under Delaware law relating to the liability of directors. This provision eliminates a
director's personal liability for monetary damages resulting from a breach of fiduciary duty,
except for liability for any:
•
transaction from which the director derives an improper personal benefit;
•
act or omission not in good faith or that involves intentional misconduct or a knowing
violation of law;
•
unlawful payment of dividends or redemption of shares; or
•
breach of a director's duty of loyalty to the corporation or its stockholders.
As permitted by the Delaware General Corporation Law, the Registrant has entered into
indemnification agreements with its directors and executive officers, in addition to
indemnification provided for in the Registrant's bylaws, and intends to enter into indemnification
agreements with any new directors and executive officers in the future. Under these agreements, the
Registrant is required to indemnify such executive officers and directors against all expenses
(including attorneys' fees), witness fees, judgments, fines, settlements and other amounts incurred in connection
with any action, suit or proceeding, or alternative dispute mechanism, inquiry, hearing or investigation, whether actual or threatened, to which any such person may be
made a party by reason of the fact that such person is or was a director, officer, stockholder, controlling person, agent or employee of
the Registrant or any of its affiliated enterprises. The Registrant's obligation to pay these
amounts is subject to the condition that it is not finally determined that any such person would not be permitted to be indemnified under applicable law. The
indemnification agreements also set forth procedures that will apply in the event of a claim for
indemnification thereunder.
The Registrant has purchased and intends to maintain insurance on behalf of any person who is
or was a director or officer of the Registrant against any loss arising from any claim asserted
against him or her and incurred by him or her in any such capacity, subject to certain exclusions.

UNDERTAKINGS
1.
The undersigned Registrant hereby undertakes:
(a)
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 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)(i) and (a)(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 herein.
(b)
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 herein, and the offering of such securities at that time shall be deemed to be
the initial
bona fide
offering thereof.
5
(c)
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.
(d)
That, for the purpose of determining liability of the Registrant under the Securities Act
of 1933 to any purchaser in the initial distribution of the securities, the undersigned Registrant
undertakes that in a primary offering of securities of the undersigned Registrant pursuant to this
registration statement, regardless of the underwriting method used to sell the securities to the
purchaser, if the securities are offered or sold to such purchaser by means of any of the following
communications, the undersigned Registrant will be a seller to the purchaser and will be considered
to offer or sell such securities to such purchaser:
(i)
Any preliminary prospectus or prospectus of the undersigned Registrant relating to the
offering required to be filed pursuant to Rule 424;
(ii)
Any free writing prospectus relating to the offering prepared by or on behalf of the
undersigned Registrant or used or referred to by the undersigned Registrant;
(iii)
The portion of any other free writing prospectus relating to the offering containing
material information about the undersigned Registrant or its securities provided by or on behalf of
the undersigned Registrant; and
(iv)
Any other communication that is an offer in the offering made by the undersigned
Registrant to the purchaser.
2.
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 the registration
statement shall be deemed to be a new registration statement relating to the securities
offered herein, and the offering of such securities at that time shall be deemed to be the
initial
bona fide
offering thereof.
3.
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
Securities and Exchange 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.
