                  (i) Amending and restating paragraph (c) of Item 4 as follows:

                  "(c) Any change in the present board of directors or

                  (ii) Deleting the last paragraph of Item 4 and adding the
following paragraphs at the end thereof:

                  "VNAC has authorized the immediate sale, in one or more
broker's transactions, of up to 684,861 Shares. Each of VNAC and Water presently
intends to fully divest its interest in the Issuer by (i) selling, pledging or
otherwise disposing of, directly or indirectly, additional Shares in the open
market and/or in negotiated transactions, (ii) issuing securities exchangeable
into any Shares, (iii) entering into any swap, hedge or other arrangements that

permitted under applicable U.S. securities laws and regulations, and until such
time as VNAC, Water and their affiliates cease to hold any Shares. VNAC and
Water will continue to review their investment position in the Issuer
periodically and, depending on such review, market conditions and share prices,
the Issuer's business, prospects and future developments and applicable legal
requirements, VNAC and Water may decide to change their divestment strategy
relating to the Shares at any time."
