                                                                       ---------
EARNINGS"  shall be deemed to mean the product  obtained by multiplying  (i) the
- --------
result  obtained by  subtracting  (A) the lesser of (1) the sum of clause (B)(2)
plus clause (B)(3),  or (2) $250,000,  from (B) the sum of (1) the Partnership's
- ----                                   ----
audited pre-tax earnings (as determined by ACI's Auditors,  whose  determination
shall be final and binding on the parties) for any applicable year, plus (2) any
                                                                    ----
amortization of goodwill  included in such earnings,  plus (3) any allocation of
                                                      ----
ACI's corporate  overhead or similar  corporate  charges of ACI included in such
earnings, by (ii) .60; the term "MULTIPLE OF EARNINGS VALUE" shall mean, for any
          --                     --------------------------
applicable  period,  the  product  obtained  by  multiplying  (i) 15 by (ii) the
Partnership's  AFTER-TAX EARNINGS for the applicable year; the term "BASE VALUE"
                                                                     ----------
shall mean (i) for the year ending December 31, 1997 - $3,861,000;  (ii) for the
year ending  December  31,  1998 - the  greater of (A) the  MULTIPLE OF EARNINGS
VALUE for the year ending  December 31, 1997, or (B)  $3,861,000;  and (iii) for
the year ending  December 31, 1999 - the greater of (A) the MULTIPLE OF EARNINGS
VALUE for the year ending  December 31, 1997, (B) the MULTIPLE OF EARNINGS VALUE
for the year ending December 31, 1998, or (C)  $3,861,000;  and the term "TARGET
                                                                          ------
VALUE" shall mean, for any applicable  year, the result,  if a positive  number,
- -----
obtained by subtracting (i) the BASE VALUE for the applicable year from (ii) the
                                                                   ----
MULTIPLE OF EARNINGS VALUE for the applicable year. On the 1998 and 1999 Release
Dates up to a maximum of 100,000  Escrow  Shares  shall be eligible  for release
from Escrow. If on either the 1998 or 1999 Release Date less than 100,000 Escrow
Shares shall be released from Escrow pursuant to the provisions hereof, then, in
each such event, a number of Escrow Shares equal to the difference between

                                      -2-


100,000  Escrow  Shares and the actual  number of Escrow  Shares  released  from
Escrow on each such  Release  Date  pursuant to the  provisions  hereof shall be
eligible for release from Escrow  pursuant to the provisions  hereof on the 2000
Release  Date.  On the 2000 Release Date the maximum  number  Escrow Shares that
shall be eligible  for release  from Escrow  pursuant to the  provisions  hereof
shall be the lesser of the sum of the Escrow  Shares not  released  from  Escrow
pursuant to the provisions hereof on the 1998 and 1999 Release Dates, or 200,000
Escrow Shares. If, in performing the calculations  hereinafter set forth for any
applicable  year,  the  MULTIPLE OF  EARNINGS  VALUE shall be less than the BASE
VALUE,  then no Escrow  Shares shall be released  from Escrow on the  applicable
Release Date.

         The actual  number of Escrow  Shares to be released on any Release Date
shall be equal to the lesser of 100,000 Escrow  Shares,  or the number of Escrow
Shares determined by multiplying (i) .54 by (ii) the result obtained by dividing
                                         --
(A) the result  obtained by multiplying  (1) .08 by (2) the TARGET VALUE for the
applicable  year by (B) $3.00.  By way of  illustration,  the  formula  would be
                 --
applied as set forth in the examples on Annex I hereto.

         In the event the Partnership shall cease to be a direct or indirect
subsidiary of ACI, whether through the disposition of ACI's ownership of the
Partnership, the sale of all or substantially all the assets of the Partnership
as a going concern, spinoff, or otherwise, the Selling Partners shall, on the
day preceding the effective date of any such transaction, immediately become
fully vested in any and all shares of ACI Common Stock still held in escrow at
such time for release based upon the audited pre-tax earnings for years not then
completed, and all such fully vested shares of ACI Common Stock shall be
released from escrow to the Selling Partners on or before the consummation of
any such transaction. Any Escrow Shares not released to the Selling Partners
pursuant hereto shall be released from Escrow and delivered to ACI on or before
the 2000 Release Date.

         Partnership and HOLD, or amendments to the Partnership's existing
         agreement or agreements with HOLD, in each case, are substantially in
         the same form and containing substantially similar terms as the present
