Earn-Out Consideration:

Sales/Projected Sales x 25% of Potential Payment (2/7 of combined SES and SASCO
Potential Payment) = Sales Payment

Profit/Potential Profit x 75% of Potential Payment (2/7 of combined SES and
SASCO Potential Payment) = Profit Payment

Sales Payment + Profit Payment = Earn-Out  Consideration

Examples:

If combined sales at October 31, 2001, are $23,000,000 and combined profit is
$1,500,000

Sale portion          23,000,000/24,200,000 = 95.04%  x 175,070  =  166,387
Profit portion         1,500,000/ 1,694,000 = 88.55%  x 525,210  =  465,073
                                                        -------     -------
 Consideration                                          700,280     631,460

If combined sales at October 31, 2002 are $28,000,000 and combined profit is
$2,150,000

Sale portion          28,000,000/27,000,000 = 103.70% x 210,084  =  217,857
Profit portion         2,150,000/ 1,890,000 = 113.76% x 630,252  =  716,978
                                                        -------     -------
 Consideration                                          840,336     934,835

The Earn-Out Consideration for Year One (ending October 31, 2000) shall be
converted into Able Common Stock by dividing the Consideration by $8.00. The
Earn-Out Consideration for each of Year Two, Year Three and Year Four shall be
converted into Able Common Stock by dividing the Earn-Out Consideration by the
52-week average of the closing market price of the Able Common Stock for each
respective year.
