EXHIBIT 11
COMPUTATION OF NET (LOSS) PER COMMON SHARE, continued

NOTE: The calculation for Net (Loss) Per Common Share - Assuming Dilution is
submitted in accordance with Securities Exchange Act of 1934 Release No. 9083
although not required by Financial Accounting Standards Board No. 128 "Earnings
Per Share" (FASB 128) since the results are anti-dilutive.

(A) - Convertible Preferred Stock has no shares issued an outstanding at
12/31/97 and 12/31/96 and therefore is not a common stock equivalent. Cumulative
Preferred Stock is not convertible into common shares even though 10 shares are
outstanding at 12/31/97 and 12/31/96 and is also not considered a common stock
equivalent.

(B) - The dilutive options (i.e. the average yearly market price is greater than
the exercise price) assume that the 1,086,010 shares exercised resulting in
proceeds of $3,818,828 are reacquired using the treasury stock method at the
yearly average market price of $5.58 per share. Thus, $3,818,828/$5.58=684,378
shares are assumed to be reacquired and are included as such in common shares
outstanding at the beginning of the year.

(C) - The dilutive warrants (i.e. the average yearly market price is greater
than the exercise price) assume that the 38,611 shares exercised resulting in
proceeds of $168,750 are reacquired using the treasury stock method at the
yearly average market price of $5.58 per share. Thus, $168,750/$5.58=30,242
shares are assumed to be reacquired and are included as such in common shares
outstanding at the beginning of the year.
