opinion in paragraph 1 with respect to the good standing of the Company, in the

opinion in paragraph 3 below with respect to the Company&#146;s qualifications to do
business as a foreign corporation, we have relied solely on (i) a certificate
of an officer of the Company as to the states in which the Company owns or

authorized to bind it by contract, (ii) a certificate of an officer of the
Company that the Company has not been requested by the authorities of any state
to qualify as a foreign corporation for the transaction of business in that
state, and (iii) an examination of certificates of good standing or documents
of similar import issued by the jurisdictions indicated in the officer&#146;s
certificate referred to in clause (i) of this paragraph and, in the case of
California, a certificate as to payment of franchise taxes issued by the
California Franchise Tax Board, and with respect to the Company&#146;s good standing
in and payment of franchise taxes to the State of California, we have, at a
minimum, obtained confirmation of good standing and payment of franchise taxes
on the business day immediately preceding the date hereof; we have made no
further investigation.</font></p>

paragraph 7 below is based upon inquiry, which has been limited to (i)
obtaining a certificate from an officer of the Company to the effect that there
are no legal proceedings pending or threatened of the type described in
paragraph 7, (ii) reviewing our files respecting all pending litigation matters
to determine that we are not acting as counsel of record for the Company, and
(iii) an inquiry of attorneys within this firm who perform legal services for
the Company as to whether they are aware of any such pending or threatened
action.&#160; We have made no further
investigation.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">During the course of
preparing the Registration Statement and Prospectus we participated in
conferences with officers and other representatives of the Company,
representatives of the independent public accountants of the Company and
representatives of the Underwriter at which the contents of the Registration
Statement and Prospectus were discussed.&#160;
We did not participate in the preparation of any of the reports filed by
the Company with the Securities and Exchange Commission under
Sections&nbsp;13(a), 13(c), 14 and 15(d) of the Exchange Act of 1934, as
amended, that are incorporated by reference in the Prospectus Supplement (the
&#147;Exchange Act Reports&#148;); however, during the course of the preparation of the
Prospectus Supplement, we reviewed the Exchange Act Reports with you and your
counsel and participated in conferences with you and your counsel and with
officers and other representatives of the Company at which the contents of the
Exchange Act Reports were discussed.&#160;
While we are not passing upon and do not assume responsibility for the
accuracy, completeness or fairness of the statements contained in the
Registration Statement or Prospectus, on the basis of the foregoing, nothing
has come to our attention that causes us to believe that the Registration
Statement (excluding all documents incorporated by reference therein other than
the Exchange Act Reports), as of the date that the Company&#146;s most recent Annual
Report on Form&nbsp;10-K was filed with the Commission, contained an untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary to make the statements therein not misleading, or that
the Prospectus (excluding all documents incorporated by reference therein other
than the Exchange Act Reports) or any supplement thereto, at the date of the
Prospectus Supplement or any supplement thereto, and at any time thereafter up
to and including the Closing Time contained or contains an untrue statement of
a material fact or omitted or omits to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light
of the circumstances under which they were made, not misleading (it being
understood that we make no statement with respect to the financial statements
and schedules and other financial and statistical data included in or
incorporated by reference in the Registration Statement or Prospectus).</font></p>
