Item
      3.
Incorporation
      of Certain Documents by Reference
The
following documents, which have heretofore been filed by the Company or the Plan
with the Securities and Exchange Commission (the "Commission") pursuant to the
Securities Act, and pursuant to the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), are incorporated by reference herein and shall be deemed
to be a part hereof:
(a)
The
      Company's latest Annual Report on Form 10-K filed pursuant to
      Sections 13(a) or 15(d) of the Exchange Act or latest prospectus filed
      pursuant to Rule 424(b) under the Securities Act that contains audited
      financial statements for the Registrant's latest fiscal year for which
      such statements have been filed;
(b)
All
      other reports filed pursuant to Section 13(a) or 15(d) of the Exchange Act
      since the end of the fiscal year covered by the Registrant's latest Annual
      Report or prospectus referred to in (a)
above;
(c)
A
      description of the Company's common stock contained in the Company's
      Registration Statement on Form 8-A (Registration No. 001-32410) filed
      pursuant to Section 12(b) of the Exchange Act, including any amendment or
      report updating such description;
and
(d)
The
      most recent Annual Report on Form 11-K filed by the Plan with respect to
      the Plan's most recently completed fiscal
year.
In
addition, all documents subsequently filed by the Company or the Plan with the
Commission pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act,
prior to the filing of a post-effective amendment to this Registration Statement
which indicates that all securities offered hereby have been sold or which
deregisters all securities remaining unsold, shall be deemed to be incorporated

this Registration Statement.
Any
statement, including financial statements, contained in a document incorporated
or deemed to be incorporated by reference herein shall be deemed to be modified
or superseded for purposes of this Registration Statement to the extent that a
statement contained herein or therein or in any other subsequently filed
document which also is or is deemed to be incorporated by reference herein
modifies or supersedes such statement.  Any such statement so modified
or superseded shall not be deemed, except as so modified or superseded, to
constitute a part of this Registration Statement.
The
Company's Exchange Act file number with the Commission is

Indemnification
      of Directors and Officers
The
Delaware General Corporation Law, or DGCL, authorizes corporations to limit or
eliminate the personal liability of directors to corporations and their
stockholders for monetary damages for breaches of directors' fiduciary
duties.  The Company's Second Amended and Restated Certificate of
Incorporation (the "Certificate of Incorporation") includes a provision that
eliminates the personal liability of directors for monetary damages for actions
taken as a director, except for liability:
·
for
      breach of duty of loyalty;
·
for
      acts or omissions not in good faith or involving intentional misconduct or
      knowing violation of law;
·
under
      Section 174 of the DGCL (unlawful dividends or stock repurchases and
      redemptions); or
·
for
      transactions from which the director derived improper personal
      benefit.
The
Company's Certificate of Incorporation and Third Amended and Restated By-laws
(the "By-laws") provide that, except in limited circumstances, the Company must
indemnify its directors and officers to the fullest extent authorized by the
DGCL and must pay in advance the expenses and costs incurred by its directors
and officers in defense of civil, criminal, administrative, regulatory and
investigative actions.  The Company is authorized to carry directors'
and officers' insurance providing indemnification for its directors, officers
and certain employees for some liabilities.
The
limitation of liability and indemnification provisions in the Company's
Certificate of Incorporation and By-Laws may discourage stockholders from
bringing a lawsuit against directors for breach of their fiduciary
duty.  These provisions also may have the effect of reducing the
likelihood of derivative litigation against directors and officers, even though
such an action, if successful, might otherwise benefit the Company and its
stockholders.

Undertakings
1.
The
      Company and the Plan hereby
undertake:
(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;
(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 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;
and
(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
(1)(a)(i) and (1)(a)(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 Commission pursuant to Section 13 or
Section 15(d) of the Exchange Act that are incorporated by reference in this
Registration Statement;
(b)
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; and
(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.
2.           The
Company and the Plan hereby further undertake that, for the purposes of
determining any liability under the Securities Act, each filing of the Company's
Annual Report pursuant to Section 13(a) or 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.
3.           Insofar
as indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers and controlling persons of the Company pursuant
to provisions and arrangements that exist whereby the Company or the Plan may
indemnify such persons against liabilities arising under the Securities Act, or
otherwise, the Company and the Plan have 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 Company of expenses incurred or paid by a director, officer or controlling
person of the Company 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 Company or the Plan 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.
