ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

            Set forth below is a description of certain provisions of the
Companies Act of 1981 of Bermuda (the "Companies Act"), the Company's Memorandum
of Association, as presently in effect, (the "Memorandum of Association"), the
Company's Bye-laws (the "Bye-laws") and the Plan, as such provisions relate to
the indemnification of the directors and officers of the Company. This
description is intended only as a summary and is qualified in its entirety by
reference to the applicable provisions of the Companies Act, the Company's
Memorandum of Association, the Company's Bye-laws and the Plan, which are
incorporated herein by reference.

         The Companies Act permits the Company to indemnify its directors or
officers in their capacity as such in respect of any loss arising or liability
attaching to them by virtue of any rule of law in respect of any negligence,
default, breach of duty or breach of trust of which a director or officer may be
guilty in relation to the Company other than in respect of his own fraud or
dishonesty.

         The Bye-laws provide that every director, officer, committee member and
any resident representative of the Company be indemnified against any
liabilities, loss, damage or expense incurred or suffered in such capacity,
subject to limitations imposed in the Companies Act. The Bye-laws further
provide that to the extent that any director, officer, committee member or
resident representative of the Company is successful in defending any
proceedings, whether civil or criminal, the Company will indemnify the
individual for all liabilities incurred in such capacity.

         Bye-law 31 stipulates that each shareholder and the Company agree to
waive any claim or right of action against any director, officer or committee
member, in respect of any failure to act or any action taken by such director,
officer or committee member in the performance of his duties with or for the
Company. The waiver does not extend to claims arising under United States
federal securities laws or any claims, rights of action arising from the fraud
of the director, officer, committee member or to recover any gain, personal
profit or advantage to which such individual is not legally entitled.

         There has not been in the past and there is not presently pending any
litigation or proceeding involving a director, officer, employee or agent of the
Company which could give rise to an indemnification obligation on the part of
the Company. In addition, except as described herein, the Board of Directors is
not aware of any threatened litigation or proceeding which may result in a claim
for indemnification.

ITEM 9.  UNDERTAKINGS.

         (a)      The Company hereby undertakes:

                  (1)   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 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 (a)(1)(i) and (a)(1)(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 by the Company pursuant to Section 13 or Section 15(d) of the
Exchange Act that are incorporated by reference in the 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 Company 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 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 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 of whether such indemnification by it is against
public policy as expressed in the Securities Act and will be governed by a final
adjudication of such issue.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

            Set forth below is a description of certain provisions of the
Companies Act of 1981 of Bermuda (the "Companies Act"), the Company's Memorandum
of Association, as presently in effect, (the "Memorandum of Association"), the
Company's Bye-laws (the "Bye-laws") and the Plan, as such provisions relate to
the indemnification of the directors and officers of the Company. This
description is intended only as a summary and is qualified in its entirety by
reference to the applicable provisions of the Companies Act, the Company's
Memorandum of Association, the Company's Bye-laws and the Plan, which are
incorporated herein by reference.

         The Companies Act permits the Company to indemnify its directors or
officers in their capacity as such in respect of any loss arising or liability
attaching to them by virtue of any rule of law in respect of any negligence,
default, breach of duty or breach of trust of which a director or officer may be
guilty in relation to the Company other than in respect of his own fraud or
dishonesty.

         The Bye-laws provide that every director, officer, committee member and
any resident representative of the Company be indemnified against any
liabilities, loss, damage or expense incurred or suffered in such capacity,
subject to limitations imposed in the Companies Act. The Bye-laws further
provide that to the extent that any director, officer, committee member or
resident representative of the Company is successful in defending any
proceedings, whether civil or criminal, the Company will indemnify the
individual for all liabilities incurred in such capacity.

         Bye-law 31 stipulates that each shareholder and the Company agree to
waive any claim or right of action against any director, officer or committee
member, in respect of any failure to act or any action taken by such director,
officer or committee member in the performance of his duties with or for the
Company. The waiver does not extend to claims arising under United States
federal securities laws or any claims, rights of action arising from the fraud
of the director, officer, committee member or to recover any gain, personal
profit or advantage to which such individual is not legally entitled.

         There has not been in the past and there is not presently pending any
litigation or proceeding involving a director, officer, employee or agent of the
Company which could give rise to an indemnification obligation on the part of
the Company. In addition, except as described herein, the Board of Directors is
not aware of any threatened litigation or proceeding which may result in a claim
for indemnification.

ITEM 9.  UNDERTAKINGS.

         (a)      The Company hereby undertakes:

                  (1)   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 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 (a)(1)(i) and (a)(1)(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 by the Company pursuant to Section 13 or Section 15(d) of the
Exchange Act that are incorporated by reference in the 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 Company 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 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 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 of whether such indemnification by it is against
public policy as expressed in the Securities Act and will be governed by a final
adjudication of such issue.
