                              ABOUT THIS PROSPECTUS

         This prospectus is part of a registration statement that we filed with

Information."

                       WHERE YOU CAN FIND MORE INFORMATION

         We have filed a registration statement on Form S-3 under the Securities

registration statement and does not contain all of the information included in
the registration statement. For further information about us and our common

PLAN OF DISTRIBUTION

         The sale or distribution of the securities may be effected directly to
purchasers by the selling stockholder or by any donee, pledgee or transferee as
principals or through one or more underwriters, brokers, dealers or agents from
time to time in one or more public or private transactions, including:

         o   block trades;

         o   on any exchange or in the over-the-counter market;

         o   in transactions otherwise than on an exchange or in the over-the-
             counter market;

         o   through the writing of put or call options relating to the
             securities;

         o   the short sales of the securities;

         o   through the lending of such securities;

         o   through the distribution of the securities by any selling
             stockholder to its partners, members or shareholders; or

         o   through a combination of any of the above.

         Any of these transactions may be effected:

         o   at market prices prevailing at the time of sale;

         o   at prices related to such prevailing market prices;

         o   at varying prices determined at the time of sale; or

         o   at negotiated or fixed prices.

         If the selling stockholder effects transactions by selling securities
to or through underwriters, brokers, dealers or agents, these underwriters,
brokers, dealers or agents may receive compensation in the form of discounts,
concessions or commissions from the selling stockholders or purchasers. These
discounts may be in excess of those customary for the types of transactions
involved.

         The selling stockholder and any brokers, dealers or agents that
participate in the distribution of the securities may be deemed to be
underwriters. Any profit on the sale of securities by them and any discounts,
concessions or commissions received by any of the underwriters, brokers, dealers
or agents may be deemed to be underwriting discounts and commissions under the
Securities Act.



                                        6








         Under the securities laws of some states, the securities may be sold in
these states only through registered or licensed brokers or dealers. In
addition, in some states, the securities may not be sold unless the securities
have been registered or qualified for sale in the state or an exemption from
registration or qualification is available and is complied with.

         The selling stockholder may also resell all or a portion of its
securities in open market transactions in reliance upon Rule 144 under the
Securities Act. In these cases, it must meet the criteria and conform to the
requirements of that rule.

         We will pay all of the costs, expenses and fees incident to the
registration, offering and sale of these securities to the public other than
commissions, fees and discounts of underwriters, brokers, dealers and agents. We
have agreed to indemnify the selling stockholders and any underwriters against
certain liabilities, including liabilities under the Securities Act. We will not
receive any of the proceeds from the sale of any of the securities by the
selling stockholder.
