SUPPLEMENT TO PAGES 1 AND 12 TO PROSPECTUS
DATED JUNE 14, 1999

We have adjusted the number of shares of common stock offered through this
prospectus to reflect a 3 to 1 stock split effected as a stock dividend. The
board of directors declared the stock split on September 8, 1999. Stockholders
of record on September 20, 1999 will be entitled to two additional shares of
common stock for each share of common stock held on that date. The payment date
for the stock dividend will be September 30, 1999. We expect that our common
stock will begin to trade on a post-split basis on October 1, 1999. To reflect
the stock split, the number of shares that may be offered through this
prospectus will increase to include three times the number of shares described
in the prospectus that the selling stockholders hold on September 30, 1999.

THE DATE OF THIS SUPPLEMENT IS SEPTEMBER 20, 1999.
