EXHIBIT 99.1
In February 1997, the Financial Accounting Standards Board issued Statement No.
128, "Earnings Per Share" ("FAS 128"), which is required to be adopted for the
period ended December 31, 1997. Statement 128 replaced the calculation of
primary and fully diluted net income per share with basic and diluted net income
per share. Unlike primary net income per share, basic net income per share
excludes any dilutive effects of options, warrants and convertible securities.
Diluted net income per share is very similar to the previously reported fully
diluted net income per share.

In February 1998, Staff Accounting Bulletin No. 98 ("SAB 98") was issued and
amends the existing Securities and Exchange Commission ("SEC") staff guidance
primarily to give effect to FAS 128.  Under SAB 98, certain shares of 
convertible preferred stock, options and warrants to purchase shares of common 
stock, issued at prices below the per share price of shares sold in the 
Company's initial public offering in December 1997 and previously included in 
the computation of shares outstanding pursuant to Staff Accounting Bulletins
Nos. 55, 64 and 83 are now excluded from the computation

All net income per share amounts for all periods have been presented, and where
appropriate, restated to conform to the FAS 128 and SAB 98 requirements:
