total registration fee of $9,647.51 is offset by the registration fee previously paid by
the Registrant with respect to unissued and unused Common Shares previously registered by
the Registrant on its Registration Statement on Form S-8 (Registration No.&nbsp;333-133521) (the
&#147;Prior Registration Statement&#148;). The amount of the registration fee was calculated as the
difference between the aggregate total registration fee of $9,647.51 (calculated based on
the number of Common Shares to be offered and sold under the 2010 Share Incentive Plan)
less $1,433.74, which represents the portion of the registration fee associated with an
aggregate of 472,977 deregistered shares, that was previously paid in connection with the
Prior Registration Statement. The Registrant is filing a post-effective amendment to its
Prior Registration Statement to deregister the 472,977 unissued Common Shares
contemporaneously with the filing of this Registration Statement.</TD>

such director or officer may be guilty in relation to the company. Section&nbsp;98 further provides
that a Bermuda company may indemnify its directors and officers against any liability incurred by
them in defending any proceeding, whether civil or criminal, in which judgment is awarded in their
favor or in which they are acquitted or if granted relief by the Supreme Court of Bermuda in

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

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 the 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 Company 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.

In addition, pursuant to Rule 416(a) under the Securities Act of 1933, as amended, this
Registration Statement also covers an indeterminate amount of Common Shares which become
issuable pursuant to the provisions of the plan listed above by reason of antidilution and other
adjustments.
(2)
Pursuant to Rule 457(h) under the Securities Act of 1933, as amended, these prices are
estimated solely for the purpose of calculating the registration fee and are based upon the
average of the high and low sales prices of the Registrant's Common Shares on the New York
Stock Exchange on April 23, 2010.
(3)
Pursuant to Rule 457(p) under the Securities Act of 1933, as amended, the aggregate
total registration fee of $9,647.51 is offset by the registration fee previously paid by
the Registrant with respect to unissued and unused Common Shares previously registered by
the Registrant on its Registration Statement on Form S-8 (Registration No. 333-133521) (the
"Prior Registration Statement"). The amount of the registration fee was calculated as the
difference between the aggregate total registration fee of $9,647.51 (calculated based on
the number of Common Shares to be offered and sold under the 2010 Share Incentive Plan)
less $1,433.74, which represents the portion of the registration fee associated with an
aggregate of 472,977 deregistered shares, that was previously paid in connection with the
Prior Registration Statement. The Registrant is filing a post-effective amendment to its
Prior Registration Statement to deregister the 472,977 unissued Common Shares
contemporaneously with the filing of this Registration Statement.

Item 6. Indemnification of Directors and Officers.
The Company is a Bermuda company. Set forth below is a description of certain provisions of
the Companies Act of 1981 of Bermuda, as amended (the "Companies Act"), and the Company's Amended
and Restated Bye-Laws, as presently in effect (the "Bye-Laws"), as such provisions relate to the

Section 98 of the Companies Act provides generally that a Bermuda company may indemnify its
directors and officers against any liability which by virtue of Bermuda law or otherwise would be
imposed on them, except in cases where such liability arises from the fraud or dishonesty of which
such director or officer may be guilty in relation to the company. Section 98 further provides
that a Bermuda company may indemnify its directors and officers against any liability incurred by
them in defending any proceeding, whether civil or criminal, in which judgment is awarded in their
favor or in which they are acquitted or if granted relief by the Supreme Court of Bermuda in
certain proceedings arising under Section 281 of the Companies Act.
The Company has adopted provisions in its Bye-Laws that provide that the Company shall
indemnify its officers and directors to the maximum extent permitted under the Companies Act.

(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 this 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 this
effective Registration Statement;
(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 (a)(1)(i) and (a)(1)(ii) do not apply if this Registration
Statement is on Form S-3, Form S-8 or Form F-3, and 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 this 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 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.
(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to
directors, officers and controlling persons of the Company pursuant to the indemnification
provisions summarized in Item 6 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 the 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 Company 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.
