<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Cayman Islands law does not limit the extent to which a company&#146;s articles of association may
provide for indemnification of officers and directors, except to the extent any such provision may
be held by the Cayman Islands courts to be contrary to public policy, such as to provide
indemnification against civil fraud or the consequences of committing a crime. The registrant&#146;s
Articles of Association provide for indemnification of officers and directors for losses, damages,
costs and expenses incurred in their capacities as such, except if they acted in a willfully
negligent manner or defaulted in any action against them. In addition, the registrant has entered
into indemnification agreements with our directors and officers.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Insofar as indemnification for liabilities arising under the Securities Act may be permitted
to directors, officers or persons controlling the registrant pursuant to the foregoing provisions,
we have been informed 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 as a matter of U.S. law.

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 hereunder, the registrant will, unless in the opinion of its counsel the matter has
already been settled by controlling precedent, submit to a court of appropriate jurisdiction the
question of 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.

INFORMATION REQUIRED IN THE REGISTRATION STATEMENT
Item 3.
Incorporation of Documents by Reference
.
The following documents filed with the Securities and Exchange Commission (the
"
Commission
") are hereby incorporated by reference:
(a)      The registrant's Annual Report on Form 10-K for the fiscal year ended December 31, 2004
pursuant to Section 13(a) of the Securities Exchange Act of 1934 (the "
Exchange Act
"),
which contains audited financial statements for the registrant's latest fiscal year for which such
statements have been filed, and Amendment No. 1 on Form 10-K/A to the Annual Report on Form 10-K
for the fiscal year ended December 31, 2004.
(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 Annual Report referred to in (a) above.
(c)      The description of the registrant's ordinary shares contained in the registrant's
Registration Statement on Form 8-A filed with the Commission under Section 12 of the Exchange Act
on April 12, 2000 including any amendment or report filed for the purpose of updating such
description.
All documents subsequently filed by the registrant pursuant to Sections 13(a), 13(c), 14 and
15(d) of the Exchange Act, prior to the filing of a post-effective amendment which indicates that
all securities offered hereby have been sold or which deregisters all securities then remaining
unsold, shall be deemed to be incorporated by reference in this registration statement and to be
part hereof from the date of filing such documents.
Item 4.

Item 5.
Interests of Named Experts and
Counsel

None.
Item 6.
Indemnification of Directors and Officers
.
Cayman Islands law does not limit the extent to which a company's articles of association may
provide for indemnification of officers and directors, except to the extent any such provision may
be held by the Cayman Islands courts to be contrary to public policy, such as to provide
indemnification against civil fraud or the consequences of committing a crime. The registrant's
Articles of Association provide for indemnification of officers and directors for losses, damages,
costs and expenses incurred in their capacities as such, except if they acted in a willfully
negligent manner or defaulted in any action against them. In addition, the registrant has entered
into indemnification agreements with our directors and officers.
Insofar as indemnification for liabilities arising under the Securities Act may be permitted
to directors, officers or persons controlling the registrant pursuant to the foregoing provisions,
we have been informed 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 as a matter of U.S. law.

Item 9.
Undertakings
.
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 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.
(2) that, for purposes 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.
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 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.
Insofar as the 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 hereunder, the registrant will, unless in the opinion of its counsel the matter has
already been settled by controlling precedent, submit to a court of appropriate jurisdiction the
question of 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.
