              To the knowledge of the Fund, during the last five years, neither
the Fund nor any of its executive officers or directors has been (i) convicted
in any criminal proceeding (excluding traffic violations or similar
misdemeanors) or (ii) a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction and as a result of such proceeding
is or was subject to a judgment, decree or final order enjoining future
violations of, or prohibiting or mandating activities subject to, federal or
state securities laws or finding any violation with respect to such laws.

Item 3.  Source and Amount of Funds or Other Consideration

              The funds for the purchases of Common Stock made by the Fund on
the open market were supplied from Dutch public sector pensioners' contributions
to the Fund.

Item 4.  Purpose of Transaction

              The Fund from time to time intends to review its investment in the
Issuer on the basis of various factors, including the Issuer's business,
financial condition, results of operations and prospects, general economic and
industry conditions, the securities markets in general and those for the
Issuer's securities in particular, as well as other developments and other
investment opportunities. Based on such review, the Fund will take such actions
in the future as the Fund may deem appropriate in light of the circumstances
existing from time to time. If the Fund believes that further investment in the
Issuer is attractive, whether because of the market price of the Issuer's
securities or otherwise, it may acquire additional securities of the Issuer
either in the open market or in privately negotiated transactions. Similarly,
depending on market and other factors, the Fund may determine to dispose of some
or all of the Common Stock currently owned by the Fund or otherwise acquired by
the Fund either in the open market or in privately negotiated transactions.

              Except as set forth above, the Fund has not currently formulated
any definitive plans or proposals which relate to or would result in: (a) the
acquisition by any person of


                                       4



additional securities of the Issuer or the disposition of securities of the
Issuer, (b) an extraordinary corporate transaction involving the Issuer or any
of its subsidiaries, (c) a sale or transfer of a material amount of the assets
of the Issuer or any of its subsidiaries, (d) any change in the present board of
directors or management of the Issuer, (e) any material change in the Issuer's
capitalization or dividend policy, (f) any other material change in the Issuer's
business or corporate structure, (g) any change in the Issuer's charter or
bylaws or other or instrument corresponding thereto or other action which may
impede the acquisition of control of the Issuer by any person, (h) causing a
class of the Issuer's securities to be deregistered or delisted, (i) a class of
equity securities of the Issuer becoming eligible for termination of
registration or (j) any action similar to any of those enumerated above.

Item 5.  Interest in Securities of the Issuer

              Except as disclosed herein, there have been no transactions by the
Fund in securities of the Issuer during the past sixty days.

              (d) To the knowledge of the Fund, no other person has the right to
receive or the power to direct the receipt of dividends from, or the proceeds
from the sale of, the Common Stock purchased by the Fund.
