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.
