section 281 of the Companies Act.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company has adopted provisions in its Bye-laws that provide that that the Company shall
indemnify its officers and directors in respect of their actions and omissions, except in respect
of their fraud or dishonesty. The Company has also entered into indemnification agreements with its directors
and certain of its officers to indemnify such persons, to the fullest extent
permitted by applicable law (except in certain limited circumstances) and the
Company&#146;s Bye-laws and Memorandum of Association, against all expenses,
judgments, fines and amounts paid in settlement actually and reasonably
incurred in connection with any threatened, pending or completed criminal,
civil, administrative or investigative action brought against such persons or
in which such person otherwise becomes involved as a witness by reason of his
or her relationship with the Company. The indemnification agreements also
provide for indemnification rights regarding proceedings brought by or in the
right of the Company.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Bye-laws provide that the shareholders waive all claims or rights of action that they
might have, individually or in right of the Company, against any of the Company&#146;s directors or
officers for any act or failure to act in the performance of such director&#146;s or officer&#146;s duties,
except in respect of any fraud or dishonesty of such director or officer. Section&nbsp;98A of the
Companies Act permits the Company to purchase and maintain insurance for the benefit of any officer
or director in respect of any loss or liability attaching to him in respect of any negligence,
default, breach of duty or breach of trust, whether or not the Company may otherwise indemnify such
officer or director. The Company has purchased and maintains a directors&#146; and officers&#146; liability
policy for such a purpose.

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 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

Table of Contents
Item 6. Indemnification of Directors and Officers
The Company is a Bermuda exempted company. Section 98 of the Companies Act 1981 of Bermuda
(the "Companies Act") provides generally that a Bermuda company may indemnify its directors,
officers and auditors against any liability which by virtue of any rule of law would otherwise be
imposed on them in respect of any negligence, default, breach of duty or breach of trust, except in
cases where such liability arises from fraud or dishonesty of which such director, officer or
auditor may be guilty in relation to the company. Section 98 further provides that a Bermuda
company may indemnify its directors, officers and auditors against any liability incurred by them
in defending any proceedings, whether civil or criminal, in which judgment is awarded in their
favor or in which they are acquitted or granted relief by the Supreme Court of Bermuda pursuant to
section 281 of the Companies Act.
The Company has adopted provisions in its Bye-laws that provide that that the Company shall
indemnify its officers and directors in respect of their actions and omissions, except in respect
of their fraud or dishonesty. The Company has also entered into indemnification agreements with its directors
and certain of its officers to indemnify such persons, to the fullest extent
permitted by applicable law (except in certain limited circumstances) and the
Company's Bye-laws and Memorandum of Association, against all expenses,
judgments, fines and amounts paid in settlement actually and reasonably
incurred in connection with any threatened, pending or completed criminal,
civil, administrative or investigative action brought against such persons or
in which such person otherwise becomes involved as a witness by reason of his
or her relationship with the Company. The indemnification agreements also
provide for indemnification rights regarding proceedings brought by or in the
right of the Company.
The Bye-laws provide that the shareholders waive all claims or rights of action that they
might have, individually or in right of the Company, against any of the Company's directors or
officers for any act or failure to act in the performance of such director's or officer's duties,
except in respect of any fraud or dishonesty of such director or officer. Section 98A of the
Companies Act permits the Company to purchase and maintain insurance for the benefit of any officer
or director in respect of any loss or liability attaching to him in respect of any negligence,
default, breach of duty or breach of trust, whether or not the Company may otherwise indemnify such
officer or director. The Company has purchased and maintains a directors' and officers' liability
policy for such a purpose.

Item 9. Undertakings
The undersigned registrant hereby undertakes:
1. (a) To file, during any period in which offers or sales are being made, a post-effective
amendment to the 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 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;
(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 (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 reports filed with or furnished to the Commission by the Company pursuant to Section 13 or
Section 15(d) of the Exchange Act that are incorporated by reference in the 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.
(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 undersigned registrant hereby undertakes that, for purposes of determining any liability
under the Securities Act, each filing of the Company'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
Table of Contents
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 the foregoing provisions, or
otherwise, the Company 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
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 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.
