Earn-Out Consideration:

--------
(1) The Consideration shall be paid in shares of Able Common Stock until the
combined Consideration calculated pursuant to the terms of this Agreement and
pursuant to the terms of the SES Merger Agreement, and which includes the
Initial Consideration and the Earn-Out Consideration, equals 19.9% of the total
Able Common Stock issued and outstanding. Any and all Consideration in excess of
19.9% of issued and outstanding Able Common Stock shall be paid in cash or by
promissory note, as mutually agreed upon by Able and the Shareholders, at the
time of payment and shall include interest calculated at the market rate.

(2) Profit shall be determined in accordance with generally accepted accounting
principles. Profit includes all revenues and expenses of the business except for
income taxes and net interest expense, and corporate overhead which will not
exceed 2 1/2% of revenues per year.

<PAGE>

Sales/Projected Sales x 25% of Potential Payment (5/7 of combined SES and SASCO
Potential Payment) = Sales Payment

Profit/Potential Profit x 75% of Potential Payment (5/7 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 137,430  =  130,613
Profit portion         1,500,000/ 1,694,000 =  88.55% x 412,290  =  365,083
                                                        -------     -------
Earn-Out Consideration                                  549,720     495,695

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 164,916  =  171,018
Profit portion         2,150,000/ 1,890,000 = 113.76% x 494,748  =  562,825
                                                        -------     -------
Earn-Out Consideration                                  659,664     733,843

The Earn-Out Consideration for Year One (ending October 31, 2000) shall be
converted into Able Common Stock by dividing the Earn-Out 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.
