ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

        None.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        Bermuda law permits a company to indemnify its directors and officers,
except for any act of fraud or dishonesty. Marvell has provided in its Bye-laws
that the directors and officers and the liquidators and trustees, if any, of
Marvell will be indemnified and secured harmless to the full extent permitted by
law out of the assets of Marvell from and against all actions, costs, charges,
losses, damages and expenses incurred by reason of any act done, concurred in or
omitted in or about the execution of their duties or supposed duties, or in
their respective offices or trusts, and none of them shall be answerable for the
acts, receipts, neglects or defaults of the others of them or for joining in any
receipts for the sake of conformity, or for any bankers or other persons with
whom any moneys or effects belonging to Marvell shall or may be lodged or
deposited for safe custody, or for insufficiency or deficiency of any security
upon which any moneys of or belonging to Marvell shall be placed out on or
invested, or for any other loss, misfortune or damage which may happen in the
execution of their respective offices or trusts, or in relation thereto, other
than in the case of any fraud or dishonesty. In addition, Marvell has provided
in its Bye-laws that each shareholder of Marvell agrees to waive any claim or
right of action, individually or in the right of Marvell, against any director
or officer of Marvell on account of any action taken by such director or
officer, or the failure of such director or officer to take any action, in the
performance of his duties with or for Marvell, other than with respect to any
matter involving any fraud or dishonesty on behalf of such director or officer.
Marvell's Bye-laws provide that the waiver is not applicable to claims arising
under United States federal securities laws.

        Bermuda law also permits Marvell to purchase insurance for the benefit
of its directors and officers against any liability incurred by them for the
failure to exercise the requisite care, diligence and skill in the exercise of
their powers and the discharge of their duties, or indemnifying them in respect
of any loss arising or liability incurred by them by reason of negligence,
default, breach of duty or breach of trust. Marvell has indemnification
insurance for its officers and directors.

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 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

        None.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        Bermuda law permits a company to indemnify its directors and officers,
except for any act of fraud or dishonesty. Marvell has provided in its Bye-laws
that the directors and officers and the liquidators and trustees, if any, of
Marvell will be indemnified and secured harmless to the full extent permitted by
law out of the assets of Marvell from and against all actions, costs, charges,
losses, damages and expenses incurred by reason of any act done, concurred in or
omitted in or about the execution of their duties or supposed duties, or in
their respective offices or trusts, and none of them shall be answerable for the
acts, receipts, neglects or defaults of the others of them or for joining in any
receipts for the sake of conformity, or for any bankers or other persons with
whom any moneys or effects belonging to Marvell shall or may be lodged or
deposited for safe custody, or for insufficiency or deficiency of any security
upon which any moneys of or belonging to Marvell shall be placed out on or
invested, or for any other loss, misfortune or damage which may happen in the
execution of their respective offices or trusts, or in relation thereto, other
than in the case of any fraud or dishonesty. In addition, Marvell has provided
in its Bye-laws that each shareholder of Marvell agrees to waive any claim or
right of action, individually or in the right of Marvell, against any director
or officer of Marvell on account of any action taken by such director or
officer, or the failure of such director or officer to take any action, in the
performance of his duties with or for Marvell, other than with respect to any
matter involving any fraud or dishonesty on behalf of such director or officer.
Marvell's Bye-laws provide that the waiver is not applicable to claims arising
under United States federal securities laws.

        Bermuda law also permits Marvell to purchase insurance for the benefit
of its directors and officers against any liability incurred by them for the
failure to exercise the requisite care, diligence and skill in the exercise of
their powers and the discharge of their duties, or indemnifying them in respect
of any loss arising or liability incurred by them by reason of negligence,
default, breach of duty or breach of trust. Marvell has indemnification
insurance for its officers and directors.

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.
