penalty and fines which should not be material.

      (b) The corporate income and payroll tax returns of DC Shoes have been
audited for fiscal years 1998, 1999 and 2000. To Quiksilver's knowledge, all
issues relating to such years, except those with respect to the 2000 corporate
income tax return, have been resolved. The primary issues raised by the IRS in
connection with each audit related to the following:

            (i) Unsubstantiated use of the corporate credit card;

            (ii) Expensing certain capital expenditures;

            (iii) Using incorrect amortization schedule lor certain capital
expenditures;

            (iv) Mischaracterization of Clayton Blehm as an independent
contractor instead of as an employee;

            (v) Failure to amortize legal expenses related to trademark
registration; and

            (vi) Issues relating to Section 263A of the Code.

      (c) The issues discussed above with respect to the federal corporate
income and payroll tax returns of DC Shoes also relate to the corresponding
California state tax returns of DC Shoes. DC Shoes has filed amended California
state corporate tax returns for fiscal years 1998 and 1999 based on the
settlement with the IRS Upon final settlement of the 2000 tax year with the
IRS, it is the intent of DC Shoes to file an amended 2000 California state
return based on the settlement with the IRS. Nonetheless, the California tax
returns have not been audited, and deficiency amounts still could be assessed
against DC Shoes in the future with respect to those tax returns for which the
statute of limitations has not expired.

      (d) The states of Washington and Arizona have informed DC Shoes that it
may be subject to franchise taxes in those slates based on the fact that DC
Shoes has employees in those states. DC Shoes has not filed returns for such
franchise taxes (or similar taxes).
