$3,000,000 plus the product of (A) $500,000 and (B) the number of

to resolve their differences and any resolution by them as to any
disputed amounts shall be final, binding and conclusive.  If

presentations by the Principal Stockholder and the Buyer, and not
by independent review, only those issues still in dispute.  The
Neutral Auditors' determination shall be made within 30 days of
their selection, whether or not such presentations by the
Principal Stockholder and the Buyer have been made within such
period, and shall be set forth in a written statement delivered
to the Principal Stockholder and the Buyer and shall be final,
binding and conclusive.  The term "Adjusted Closing Date
Statement," as hereinafter used, shall mean the definitive
Closing Date Statement agreed to by the Principal Stockholder and
the Buyer in accordance with Section 6.5(b) or the definitive
Closing Date Statement resulting from the determinations made by

any increase to or reduction of Net Cash Balances pursuant to
this Section 6.5 shall be paid by wire transfer in immediately

Stockholder or the Buyer, as the case may be, within five
business days after the Adjusted Closing Date Statement is agreed
to or any remaining disputed items are ultimately determined by
the Neutral Auditors.

          6.6  Discussions with Others.  From the date hereof
until the Closing Date Sellers will not and will not permit the
Operating Companies, nor shall the Sellers authorize or knowingly
permit any officer, director, employee or representative of
Sellers or the Operating Companies, to solicit or enter into

purchase and sale of any portion of the capital stock of the
Operating Companies, any material portion of the assets of the
Operating Companies or any merger or consolidation of the
Operating Companies with any third party.

time prior to the Closing, the Principal Stockholder and Buyer
will promptly supplement or amend the sections of the Disclosure
Schedule relating to their respective representations and
warranties in this Agreement with respect to any matter,
condition or occurrence hereafter arising which, if existing or
occurring at the date of this Agreement, would have been required
to be set forth or described in their respective sections of the
Disclosure Schedule.  Except with respect to a supplement or
amendment not objected to in writing by the other party within
five business days after receipt thereof, no supplement or
amendment by either party shall have any effect for the purpose
of (i) determining satisfaction by Sellers of the conditions set
forth in Sections 8.1(a) and 8.2(b) hereof or the compliance by
Sellers with the covenant set forth in Section 6.1 hereof or (ii)
determining satisfaction by Buyer of the conditions set forth in

shall be liable for, and shall indemnify, defend, and hold the
Buyer and its Affiliates harmless against, any and all Taxes of,
or payable by, the Operating Companies for any taxable year or
taxable period ending on or before the Closing Date, including,
but not limited to, the Illinois Replacement Tax and any other
income or franchise Tax imposed with respect to the built-in gain
in the assets of the Operating Companies as of the Closing Date,
whether such Tax is imposed (with respect to the taxable year
that includes the Closing Date or, on account of any payments
pursuant to Sections 2.2(c) through (i).  The Sellers shall
timely file or cause to be filed all Tax Returns relating to the
Operating Companies for any taxable year ending on or before the
Closing Date.  The Sellers shall determine the amount of taxable
income of the Operating Companies on the basis of its permanent
records and consistent with the past income tax accounting
methods utilized in preparing its prior income tax returns,
except as otherwise required by law.

               (b)  Liability of the Buyer and the Sellers for
Taxable Periods Commencing Before and Ending After the Closing
Date.  The Buyer shall cause each Operating Company to pay all
Taxes due from such Operating Company for any taxable year or
taxable period commencing before and ending after the Closing
Date (the "Split Tax Period").  Upon timely notice from the
Buyer, the Sellers shall pay to such Operating Company prior to
the due date for such Taxes an amount equal to the amount of such
Taxes that have not been paid as of the Closing Date and would
have been due from such Operating Company if the Split Tax Period
had ended on the Closing Date.

               (c) Liability of the Buyer for Taxable Periods
Commencing After Closing Date.  The Buyer and the Operating
Companies shall be liable for, and shall indemnify and hold the
Sellers and any of their respective Affiliates harmless against,
(i) any and all Taxes of, or payable by, the Operating Companies
for any taxable year or taxable period commencing after the
Closing Date and (ii) any Taxes relating to operations, acts or
omissions of the Buyer or the Operating Companies that occur
after the Closing on the Closing Date.

               (d)  Refunds or Credits.  Any refunds or credits
attributable to Taxes for which the Sellers are liable pursuant
to Section 6.12(a) or (b) shall be solely for the account of the
Sellers, and, to the extent that such refunds or credits are
attributable to Taxes for which the Buyer is liable pursuant to
Section 6.12(b) or (c), such refunds or credits shall be solely
for the account of the Buyer.  The Buyer shall cause the
Operating Companies promptly to forward to the Sellers or to
reimburse the Sellers for any such refunds or credits due the
Sellers after receipt thereof by either the Buyer or the
Operating Companies, and the Sellers shall promptly forward to
the Operating Companies or reimburse the Operating Companies for
any refunds or credits due the Operating Companies after receipt
thereof by the Sellers of such refunds or credits that are for
the account of the Operating Companies hereunder.

               (e)  Mutual Cooperation.  As soon as practicable,
but in any event within 30 days after the Sellers' or the Buyer's
request, as the case may be, the Buyer shall or shall cause the
Operating Companies to deliver to the Sellers, or the Sellers
shall deliver to the Buyer, such information and other data in
the possession of the Sellers, the Buyer or the Operating
Companies, as the case may be, relating to the Tax Returns and
Taxes of, or with respect to, the Operating Companies, including
such information and other data customarily required by the
Sellers or the Buyer, as the case may be, to cause the payment of
all Taxes or to permit the preparation of any Tax Returns for
which it has responsibility or liability or to respond to audits
by any taxing authorities with respect to any Tax Returns or
Taxes for which it has any responsibility or liability under this
Agreement or otherwise or to otherwise enable the Sellers or the
Buyer, as the case may be, to satisfy its accounting or Tax
requirements.  For a period of seven years after the Closing,
and, if at the expiration thereof any Tax audit or judicial
proceeding is in progress or the applicable statute of
limitations has been extended, for such longer period as such
audit or judicial proceeding is in progress or such statutory
period is extended, each party shall maintain and make available
to the other, on reasonable request, copies of any and all
information, books and records referred to in this Section
6.12(e).  After such period, any party may dispose of such
information, books and records, provided that prior to such
disposition such party shall give the other a reasonable
opportunity to take possession of such information, books and
records.

               (f)  Contests.  Whenever any taxing authority
asserts a claim, makes an assessment or otherwise disputes or
affects the Tax reporting position of the Operating Companies for
periods ending on or prior to the Closing Date or the amount of
Taxes for which the Sellers are or may be liable under this
Agreement, the Buyer shall, promptly upon receipt by the Buyer or
the Operating Companies of notice thereof, inform the Sellers,
and the Sellers shall have the right to control any resulting
proceedings and to determine whether and when to settle any such
claim, assessment or dispute, but only to the extent such
proceedings or determinations affect the Tax reporting position
of the Operating Companies for periods ending on or prior to the
Closing Date or the amount of Taxes for which the Sellers are
liable under this Agreement, and not in a manner that binds the
Operating Companies' Tax reporting position for taxable periods
following the Closing Date, without the consent of the Buyer,
which shall not be unreasonably withheld.  Whenever any taxing
authority asserts a claim, makes an assessment or otherwise
disputes the amount of Taxes for which the Buyer is liable under
this Agreement, the Sellers shall, promptly upon receiving notice
thereof, inform the Buyer.  The Buyer shall have the right to
control any resulting proceedings and to determine whether and
when to settle any such claim, assessment or dispute; provided

"determination" (as described in Section 1313 of the Code).

          (ii)  The Buyer shall be responsible for the
preparation and filing of all Section 338 Forms in accordance
with applicable tax laws and the terms of this Agreement, and the
Buyer shall deliver such forms and related documents to the
Sellers at least forty (40) days prior to the date such Section
338 Forms are required to be filed under applicable tax laws.
The Sellers shall execute and deliver to the Buyer such documents
or forms as are reasonably requested by the Buyer and are
required by any tax laws to properly complete the Section 338
Forms, no more than twenty (20) days after the date such

Claimants (utilized by Buyer Claimants against income of Buyer
Claimants in the year that Buyer Claimants deducts such

additional taxes that may be incurred by Seller Claimants from
treatment of such indemnification payments as taxable income or
gain to Seller Claimants) tax benefit to Seller Claimants
(utilized by Seller Claimants against income of Seller Claimants
in the year that Seller Claimants deducts such liability, loss,
claim, cost or expense in its income tax returns, regardless of
whether Seller Claimants receives any tax benefits in any other
year by reason of any net operating loss or other available
income tax carryforwards or carrybacks), resulting from such
Claims.

          9.4  Exclusive Remedy.  Any indemnity obligations of
the Sellers pursuant to Section 9.2 hereof (other than indemnity
obligations arising from a breach of Sections 4.3(c) or 4.3(d)

the calendar month in which the Closing Date occurred), shall be
satisfied solely by payment from the Escrow Account, upon the
terms and subject to the conditions set forth in Section 9.2

agree that the remedies provided in this Agreement are their
exclusive remedies with respect to actions, occurrences or events
that took place on or prior the Closing Date, whether or not an
equitable, legal or administrative action has been commenced as
of the Closing Date with respect to such actions, occurrences or
events.

          9.5  Terms and Conditions of Indemnification.  The

following terms and conditions:

          (a)  The party seeking indemnification (the "Claimant")
must give the other party or parties, as the case may be (the
"Indemnitor"), written notice of any such claim promptly.  The
Claimant's failure to give prompt notice, however, shall not
serve to eliminate or limit the Claimant's right to
indemnification hereunder except to the extent such failure
prejudices the rights of the Indemnitor.

          (b)  The respective obligations and liabilities of
Sellers and of Buyer to indemnify pursuant to this Article IX in
respect of any Claim by a third party shall be subject to the
following additional terms and conditions:

to undertake such defense, or within a reasonable time after
notice of any such claim from the Claimant shall fail to defend,
the Claimant (upon further written notice to the Indemnitor)
shall have the right to undertake the defense, compromise or
settlement of such claim, by counsel or other representatives of
its own choosing, on behalf of and for the account and risk of
the Indemnitor.

          (iii)  Notwithstanding anything in this Section 9.4 to
the contrary, (A) if there is a reasonable probability that a
Claim may materially and adversely affect the Claimant other than
as a result of money damages or other money payments, the
Claimant shall have the right, at its own cost and expense, to
participate in the defense, compromise or settlement of the
Claim, (B) the Indemnitor shall not, without the Claimant's
written consent, settle or compromise any Claim or consent to
entry of any judgment which does not include as an unconditional
term thereof the giving by the claiming party or the plaintiff to
the Claimant of a release from all liability in respect of such
claim, and (C) in the event that the Indemnitor undertakes
defense of any Claim, the Claimant by counsel or other
representative of its own choosing and at its sole cost and
expense, shall have the right to consult with the Indemnitor and
its counsel or other representatives concerning such claim and
the Indemnitor and the Claimant and their respective counsel or
other representatives shall cooperate with respect to such claim,
subject to the execution and delivery of a mutually satisfactory
joint defense agreement.

          9.6  Treatment of Payments.   The Buyer and the Sellers
agree to treat all payments pursuant to Sections 2.2, 9.2 and 9.3
as adjustments (i.e., reductions or increases, as the case may
be) of the Purchase Price for income tax purposes and file all
income Tax Returns in a manner consistent with such treatment,
unless (i) otherwise required by a court of competent
jurisdiction or (ii) such party receives a written opinion from a
nationally recognized law firm (which opinion and law firm shall
be reasonably acceptable to the other party) that there is no
substantial authority (within the meaning of Section
6662(d)(2)(B)(i) of the Code) for such position.

                          ESCROW

          10.1  Establishment of Escrow Account.  The Principal
Stockholder and the Buyer shall, on or prior to the Closing Date,
establish the Escrow Account.

          10.2  Funding of and Withdrawals From Escrow Account.

remitted to the Principal Stockholder in accordance with the
terms and conditions set forth in the Escrow Agreement.

                           ARTICLE XI

                         MISCELLANEOUS

          11.1  Termination; Liquidated Damages.  (a) This
Agreement may be terminated and abandoned by Buyer or Sellers, by
written notice to the other party, if the transactions
contemplated by this Agreement have not been consummated by
October 1, 1997, unless the failure of such consummation shall be
due to the failure of the party seeking to terminate this
Agreement to comply in all material respects with the agreements
and covenants contained herein to be performed by such party on
or before such date.  This Agreement may be terminated by mutual
consent of the parties at any time.

          (b)  Buyer understands that the damages which may be
suffered by Sellers if Buyer fails to complete the Closing in a
timely fashion as a result of its breach of this Agreement shall
be difficult to ascertain and the parties therefore agree that
the Sellers shall be entitled (in addition to the expenses to be
paid by Buyer pursuant to Section 11.2 below) (i)to liquidated
damages in an amount equal to that number of Buyer Shares
determined by dividing (A) $2,000,000 by (B) the average last
reported sale price ADS Common Stock for the twenty trading days
immediately preceding the date of breach and (ii) a certified
copy of the Financial Statements.  Under the circumstances
described in this Section, Buyer will issue such Buyer Shares to
Seller.  The liquidated damages and Financial Statements referred
to in this Section 11.1(b) shall be Sellers' only remedy in the
event of Buyer's failure to complete the Closing in a timely
manner as a result of Buyer's breach of this Agreement and
Sellers hereby waive any further rights in connection therewith.

          11.2  Expense.  Except for sales, transfer and other
similar taxes, levies and charges that may be imposed, levied or
assessed in connection with the consummation of the transactions
contemplated hereby, which will be paid 1/2 by Buyer and 1/2 by
Sellers, and the fees and expenses incurred in connection with
the preparation of the Financial Statements, which will be paid
by Buyer, each party hereto shall pay its own expenses incurred
in connection with this Agreement and the transactions
contemplated hereby.

          11.3  Amendment.  This Agreement may not be modified,
amended, altered or supplemented except by a written agreement
executed by Buyer and Sellers.

          11.4  Entire Agreement.  This Agreement, together with
the Exhibits and Schedules hereto, the other Transaction
Documents and the instruments and other documents delivered
pursuant to this Agreement and the other Transaction Documents,
contain the entire agreement of the parties relating to the
subject matter hereof, and supersede all prior agreements,
understandings, representations, warranties and covenants of any
kind between the parties.  All others are specifically waived.

          11.5  Waivers.  Waiver by any party of any breach of or
failure to comply with any provision of this Agreement by the
other party shall not be construed as, or constitute, a
continuing waiver of such provision, or a waiver of any other
breach of, or failure to comply with, any other provision of this
Agreement.  No waiver of any such breach or failure or of any
term or condition of this Agreement shall be effective unless in
a written notice signed by the waiving party and delivered, in
the manner required for notices generally, to each affected
party.

          11.6  Notices.  All notices and other communications
