of the First Earnout  Amount.  The per share  valuation  price of such ADS Stock
shall be based upon the  average  market  closing  price of ADS Stock for the 10
consecutive  business days up to and including  September 30, 2001 (if September
30, 2001 is not a business  day,  the last day of such period  shall be the last
business day immediately  prior to September 30, 2001), as published in The Wall
Street Journal, Eastern Edition (the "First Valuation Price").

                  As used herein,  the "Fee Percentage" shall mean (A) 4% to the
extent the total of the First Earnout  Payment,  the Second Earnout  Payment (as
hereinafter  defined) and the amount of the fees to Capital Alliance Corporation
is equal to or less than $39,480,  900 and (B) 8% with respect to the amount, if

                                       4
<PAGE>

any, that the total of the First Earnout Payment, the Second Earnout Payment and
the amount  payable to Capital  Alliance  Corporation  pursuant to clause (A) of
this sentence exceeds $39,480,900.

                      In the event the Surviving  Company's EBITDA for the First
Earnout  Period is less than the  Projected  EBITDA  Amount,  the First  Earnout
Amount,  if any,  shall be reduced by an amount equal to 4.0 times the shortfall
from the Projected EBITDA Amount.

                      (iii) On the earlier of (A) December 1, 2002,  and (B) the
date 10  business  days after the date on which the  Earnout  Financials  of the
Surviving Company for the 12 month period commencing  October 1, 2001 and ending
September  30, 2002 (the "Second  Earnout  Period") are  completed and have been
subjected to certain Agreed Upon  Procedures,  which ADS shall cause to occur as
soon as reasonably practicable,  by independent accountants retained by ADS, ADS
shall deliver a third payment (the "Second Earnout Payment"). The Second Earnout
Payment shall be in the form of cash and/or ADS Stock, the  proportional  amount
to be  determined by ADS,  having a value of $9,662,947  plus an amount equal to
4.0 times the  EBITDA in excess of the  Projected  EBITDA  Amount for the Second
Earnout Period (the "Second Earnout  Amount").  ADS shall also, on behalf of the
Company,  issue and deliver to Capital Alliance Corporation restricted shares of
ADS Stock equal in value to the Fee Percentage of the Second Earnout Amount. The
per share  valuation  price of such ADS Stock  shall be based  upon the  average
closing market price of ADS Stock for the 10 consecutive business days up to and
including  September  30, 2002 (if September 30, 2002 is not a business day, the
last day of such period  shall be the last  business  day  immediately  prior to
September 30, 2002),  as published in The Wall Street  Journal,  Eastern Edition
(the "Second Valuation Price").

                      In the event that the Surviving  Company's  EBITDA for the
Second  Earnout  Period is less than the Project  EBITDA  Amount,  Buyers  shall
reduce the Second Earnout Amount due, an amount equal to 4.0 times the shortfall
from the Projected EBITDA Amount.

                      In no event shall the amount of cash paid, if any,  exceed
an  amount  greater  than  40% of the  aggregate  consideration  paid as  Merger
Consideration.

                  (b)  "EBITDA"  for a given  period  shall mean  earnings  from
operations of the  Surviving  Company for such period  before  interest,  taxes,
depreciation  and  amortization,  determined  in  accordance  with United States
generally  accepted  accounting  principles  on  a  basis  consistent  with  the
Company's historical  practices ("GAAP"),  excluding the impact on EBITDA of (i)
any management fees, consulting fees or similar payments (including  allocations
of overhead) imposed by ADS or its affiliates on the Surviving Company following
the  Closing,   (ii)  any  charges  or  expenses  related  to  the  transactions
contemplated  herein,  (iii) any acquisition or proposed  acquisition of another
business  and the  subsequent  operations  thereof,  (iv) the costs and expenses
incurred by the Company in connection  with this Agreement and the  transactions
contemplated hereby and (v) fees paid for non-recurring or unusual  professional
services  that are  outside  of the  ordinary  course of  business  and were not
contemplated in the Company's projections, which services shall include, but not
be limited to, fees paid for accounting audits.

                                       5

                  (c)  "Agreed  Upon  Procedures"  shall  mean that the  Earnout
Financials will be prepared from the books and records of the Surviving  Company
in accordance with GAAP.

                  (d)  After  receipt  of  the  Earnout  Financials,  any of the
Stockholders  shall have 15 business days to object, in writing,  to the Earnout
Financials  or any of the Earnout  Amounts as  determined  by ADS.  Such writing
shall provide detail as to the nature and amount contested.

                      (i) If the  Stockholders  do not so  object,  the  Earnout
Financials  and the Earnout  Amounts,  as the case may be, if any, as originally
prepared and determined under this Section and shall become final and binding on
the parties.

                      (ii)  If the  Stockholders  do so  object  to the  Earnout
Financials or any portion thereof or either of the Earnout Amounts,  the parties
shall promptly attempt to resolve such  objections.  In or the event the dispute
is  not  resolved  within  30  days  of  Stockholders'  written  objection,  the
Stockholders  may designate a certified  public  accountant of their choice (the
"Stockholders'  Accountants")  to prepare and/or review the Earnout  Financials.
ADS shall provide full access to  Stockholders'  Accountant and otherwise  fully
cooperate in connection  with its review of the  preparation of any such reports
and the calculation of the Earnout Amount,  provided,  however, that in no event
shall the preparation of such reports by Stockholders' Accountant take more than
45 days from the designation by the Stockholders of the Stockholders' Accountant
unless ADS fails to provide such access. In any event, if the difference between
the amount determined by the Stockholders'  Accountant and the Earnout Amount as
calculated  is  less  than  $20,000,   Stockholders   shall  pay  all  costs  of
Stockholders' Accountant.

                  In the event that, after the above process is complete,  it is
determined that by the Stockholders'  Accountants the Earnout  Financials or the
calculation  of  the  Earnout  Amount,  was  correct  as  initially  calculated,
Stockholders  shall also,  in addition to paying for the costs of  Stockholders'
Accountant,  be responsible for the  incremental  expense  incurred,  if any, of
ADS's accountant;  provided,  however,  if it is determined by the Stockholders'
Accountants  that the Earnout Amount or the  calculation of the Earnout  Amount,
was  not  correct  as  initially   calculated,   ADS  shall  pay  all  costs  of
Stockholders'  Accountant. In the event that the Earnout Amount as calculated is
greater than $20,000, ADS shall pay all the costs of Stockholders' Accountant.

                  If  the  parties  are  unable  to  arrive  at  an   acceptable
resolution,  the parties  shall  submit the dispute to a  nationally  recognized
independent  accounting  firm that is mutually  agreeable  to the parties  (such
accounting firm, the "Arbiter"),  for resolution;  provided such accounting firm
has  not  had a  professional  material  relationship  with  either,  any of the
Principal  Stockholders  or  ADS,  or any  of its  affiliates,  within  2  years
preceding the appointment.  If the parties cannot agree on the selection of such
an independent  accounting firm to act as Arbiter, the parties shall request the
American  Arbitration  Association to appoint such a firm, and such  appointment
shall be conclusive and binding upon the parties. Promptly, but no later than 20
days after its  acceptance  of its  appointment  as Arbiter,  the Arbiter  shall
determine,   based  solely  on  presentations  by  ADS  and  the   Stockholders'
Representative,  and not by independent review, only those issues in dispute and
shall  render a report as to the dispute and the  resulting  computation  of the

                                       6
<PAGE>

disputed Earnout Amount, which shall be conclusive and binding upon the parties.
In resolving any disputed  item,  the Arbiter may not assign a value to any item
greater  than the  greatest  value for such item claimed by either party or less
than the smallest value for such item claimed by either party.  The fees,  costs
and  expenses  of the  Arbiter  (i)  shall be borne by the  Stockholders  in the
proportion that the aggregate  dollar amount of such disputed items so submitted
that are unsuccessfully disputed by the Stockholders' Representative (as finally
determined by the Arbiter) bears to the aggregate dollar amount of such items so
submitted  and (ii) shall be borne by ADS in the  proportion  that the aggregate
dollar amount of such disputed items so submitted that are successfully disputed
by the Stockholders' Representative (as finally determined by the Arbiter) bears
to the  aggregate  dollar  amount  of  such  items  so  submitted.  ADS  and the
Stockholders'  Representative  each shall make  available to the other (upon the
request of the other) their  respective work papers generated in connection with
the preparation or review of the Earnout Financials.


            1.06. Closing Balance Sheet; True-up Payment.

                  (a) As promptly as practicable but in any event within 90 days
following  the Closing Date,  ADS shall  prepare,  or cause to be prepared,  and
deliver to the Stockholders'  Representative (as hereinafter defined) an audited
balance sheet of the Company and the Subsidiaries as of the close of business on
the day immediately  preceding the Closing Date (the "Closing  Balance  Sheet").
There shall be attached to the Closing  Balance  Sheet an annex setting forth in
reasonable  detail the computation of the True-up Payment (as defined in Section
1.06(d)).

                  (b) The Closing  Balance Sheet shall be prepared in accordance
with GAAP,  determined  as of 11:59 p.m. on the day  immediately  preceding  the
Closing Date as if such date was the Company's normal year-end.

                  (c)  The  Closing  Balance  Sheet  delivered  by  ADS  to  the
Stockholders'  Representative and the computation of the True-up Payment annexed
thereto   shall  be  conclusive   and  binding  upon  the  parties   unless  the
Stockholders'  Representative,   within  15  days  after  the  delivery  to  the
Stockholders'  Representative  of the Closing  Balance  Sheet,  notifies  ADS in
writing that the  Stockholders'  Representative  disputes any of the amounts set
forth therein,  specifying the nature of the dispute and the basis therefor. The
parties shall in good faith  attempt to resolve any dispute,  in which event the
Closing Balance Sheet and the computation of the True-up Payment,  as amended to
the  extent  necessary  to  reflect  the  resolution  of the  dispute,  shall be
conclusive and binding upon the parties.  If the parties do not reach  agreement
resolving the dispute within 10 days after notice is given by the  Stockholders'
Representative  to ADS pursuant to the second  preceding  sentence,  the parties
shall submit the dispute to the Arbiter for  resolution.  If the parties  cannot
agree on the selection of such  Arbiter,  the parties shall request the American
Arbitration  Association to appoint such a firm, and such  appointment  shall be
conclusive and binding upon the parties;  provided such  accounting firm has not
had a  professional  material  relationship  with either,  any of the  Principal
Stockholders  or ADS, or any of its  affiliates,  within 2 years  preceding  the
appointment.  Promptly,  but no later than 20 days after its  acceptance  of its

                                       7
<PAGE>

appointment  as  Arbiter,   the  Arbiter  shall   determine,   based  solely  on
presentations  by  ADS  and  the  Stockholders'   Representative,   and  not  by
independent review, only those issues in dispute and shall render a report as to
the dispute and the resulting  computation of the Closing  Balance Sheet and the
True-up Payment, if any, which shall be conclusive and binding upon the parties.
In resolving any disputed  item,  the Arbiter may not assign a value to any item
greater  than the  greatest  value for such item claimed by either party or less
than the smallest value for such item claimed by either party.  The fees,  costs
and  expenses  of the  Arbiter  (i)  shall be borne by the  Stockholders  in the
proportion that the aggregate dollar amount of such  disputed items so submitted
that are unsuccessfully disputed by the Stockholders' Representative (as finally
determined by the Arbiter) bears to the aggregate dollar amount of such items so
submitted  and (ii) shall be borne by ADS in the  proportion  that the aggregate
dollar amount of such disputed items so submitted that are successfully disputed
by the Stockholders' Representative (as finally determined by the Arbiter) bears
to the  aggregate  dollar  amount  of  such  items  so  submitted.  ADS  and the
Stockholders'  Representative  each shall make  available to the other (upon the
request of the other) their  respective work papers generated in connection with
the preparation or review of the Closing Balance Sheet.

                  (d) As used herein, (i) the term "Final Closing Balance Sheet"
shall mean the Closing  Balance  Sheet which has become  conclusive  and binding
upon the parties  pursuant to paragraph (c) of this Section 1.06,  (ii) the term
"Closing  Book Value" shall mean the amount  obtained by  subtracting  the total
liabilities  of the Company,  as set forth in the Final Closing  Balance  Sheet,
from the total assets of the Company,  as set forth in the Final Closing Balance
Sheet,  and (iii) the term "Target Book Value" shall mean the amount obtained by
subtracting  the total  liabilities  of the Company from the total assets of the
Company as set forth on June 30, 2000 Balance Sheet (as hereinafter defined) and
attached as Schedule 2.04(a).  If the Target Book Value exceeds the Closing Book
Value, the amount of such excess shall be the "True-up  Payment." If the True-up
Payment is greater than zero, the amount  thereof shall be paid by  Stockholders
to ADS in accordance with the provisions of paragraph (e) of this Section 1.06.

                  (e) Any amount payable as True-up Payment shall be paid in the
restricted  shares of ADS Stock received from ADS at Closing,  equal in value to
the True-up Payment or if such shares of ADS Stock have been registered, by wire
transfer of immediately  available funds to an account  designated in writing by
ADS. The  valuation  of the ADS Stock shall be based upon the Closing  Valuation
Price.  Such payment  shall be made on the third  business day following (i) the
last  day on which  Stockholders'  Representative  may,  pursuant  to the  first
sentence of paragraph (c) of this Section 1.06,  notify ADS that he disputes any
of the  amounts  set  forth  in the  Closing  Balance  Sheet,  if  Stockholders'
Representative  shall not notify ADS of any dispute, or such earlier date as the
Stockholders'  Representative shall advise ADS of the absence of any dispute, or
(ii) the date  mutual  agreement  is  reached  as to the  amount of the  True-up
Payment,  if any,  in the  event of a dispute  that is  settled  by the  parties
without resort to the Arbiter, or (iii) the receipt of the report of the Arbiter
in the event of a dispute which is settled by the Arbiter, as applicable.

                   (f) ADS shall provide the Stockholders and their  accountants
reasonable  access  to the  books  and  records  of the  Company,  to any  other

                                       8
<PAGE>

information,  including work papers of its accountants,  and to any employees of
ADS and the Company to the extent  reasonably  necessary  for the  Stockholders'
Representative   to  review  the  Closing  Balance  Sheet.   The   Stockholders'
Representative  shall provide ADS and its accountants  reasonable  access to the
books and records of the Stockholders'  Representative,  any other  information,
including work papers of its accountants, to the extent reasonably necessary for
ADS in  connection  with the  preparation  of the Closing  Balance  Sheet and in
connection  with any  objections  to the  Closing  Balance  Sheet  raised by the
Stockholders.

                                   ARTICLE II

            REPRESENTATIONS AND WARRANTIES OF PRINCIPAL STOCKHOLDERS

            The  Principal  Stockholders  jointly and  severally  represent  and
warrant  that the  statements  contained  in this  Article  II are  correct  and
complete as of the date of this Agreement and will be correct and complete as of
the Closing Date as follows:

            2.01.  Capitalization.  The authorized  capital stock of the Company
consists of 10,000,000  shares of common stock,  without par value per share, of
which  5,719,500 are issued and  outstanding.  All of the shares  comprising the
Pacific Stock are validly issued,  fully paid and  non-assessable  and are owned
beneficially  and of  record by each of the  Stockholders  free and clear of all
liens,  security interests,  restrictions,  options,  proxies,  voting trusts or
other  encumbrances  ("Encumbrances").   There  are  outstanding  no  securities
convertible  into,  exchangeable  for, or carrying the right to acquire,  equity
securities of the Company, or subscriptions,  warrants, options, rights or other
arrangements or commitments obligating the Company to issue or dispose of any of
its equity securities or any ownership  interest therein.  All of the issued and
outstanding  shares  of  Pacific  Stock  were  issued  in  compliance  with  all
applicable state and federal securities law.

            2.02. Organization; Subsidiaries.

                  (a) The  Company  is a  corporation  duly  organized,  validly
existing  and  in  good  standing  under  the  laws  of  its   jurisdiction   of
incorporation  and has all requisite  corporate  power and authority to carry on
its business as it is now being  conducted.  The Company is duly qualified to do
business and is in good standing as a foreign  corporation in all  jurisdictions
where the  nature of the  property  owned or leased by it, or the  nature of the
business conducted by it, makes such qualification  necessary and the absence of
such  qualification  would,  individually  or in the  aggregate,  have a Company
Material  Adverse Effect (as hereinafter  defined).  True and complete copies of
the charter  documents and bylaws of the Company have  previously been delivered
to Buyers.  True and  complete  copies of the minute  books of the Company  have
previously  been made available to Buyers.  The term "Company  Material  Adverse
Effect"  means any  adverse  change or effect  that when taken  individually  or
together with all other adverse changes and effects,  is or is reasonably likely
to be materially adverse to the business,  operations,  results of operations or
financial condition of the Company.

                                       9
<PAGE>

                  (b) Schedule 2.02(b) sets forth a list, as of the date hereof,
of all irect or indirect  entities  in which the Company has an equity  interest
(the "Subsidiaries"). Except as set forth in Schedule 2.02(b), the Company owns,
either directly or indirectly, all of the capital stock of the Subsidiaries free
and  clear of any  Encumbrance.  All of the  issued  and  outstanding  shares of
capital  stock  of  the  Subsidiaries   are  validly  issued,   fully  paid  and
non-assessable.  Except as set forth in Schedule 2.02(b),  there are outstanding
no  securities  convertible  into,  exchangeable  for, or carrying  the right to
acquire,  equity  securities  of  any  of the  Subsidiaries,  or  subscriptions,
warrants,  options,  rights or other arrangements or commitments  obligating any
Subsidiary  to issue or acquire any of its equity  securities  or any  ownership
interest therein.

            2.03.  Corporate  Power and  Authority;  Effect of  Agreement.  This
Agreement  has been duly and validly  executed and  delivered by each  Principal
Stockholder and  constitutes the valid and binding  obligation of such Principal
Stockholder,  enforceable against such Principal  Stockholder in accordance with
its terms,  except to the extent that such  enforceability (i) may be limited by
bankruptcy,  insolvency,  reorganization,   moratorium  or  other  similar  laws
relating  to  creditors'  rights  generally,  and  (ii) is  subject  to  general
principles of equity. The execution,  delivery and performance by such Principal
Stockholder of this Agreement and the consummation by such Principal Stockholder
of the transactions  contemplated hereby will not, with or without the giving of
notice  or the  lapse of  time,  or both,  (w) to such  Principal  Stockholder's
knowledge,  violate, or require any consent under, any Commitment (as defined in
Section  2.08),  except as set forth in Schedule  2.08(b),  (x) violate any law,
rule or  regulation  to which such  Principal  Stockholder  or the  Company  are
subject or require any  authorization,  consent,  approval,  exemption  or other
action  by or notice to any  governmental  authority,  (y)  violate  any  order,
judgment or decree  applicable to such  Principal  Stockholder or the Company or
(z) violate any provision of the charter documents or the bylaws of the Company,
except, in each case, for violations which in the aggregate would not materially
hinder or impair the consummation of the transactions contemplated hereby.

            2.04. Financial Statements.

                  (a)  The  Stockholders   have  delivered  to  Buyers  (i)  the
unaudited  balance sheets of the Company as of June 30, 2000 (the "June 30, 2000
Balance  Sheet") and  unaudited  statement of  operations  and cash flows of the
Company for the year then ended,  and (ii) audited balance sheets of the Company
as of June 30, 1999 and audited  statement of  operations  and cash flows of the
Company for the year then ended,  including the  footnotes  thereto (the "Annual
Financial  Statements")  (the  financial  statements  listed  in (i)  and  (ii),
collectively,  the  "Financial  Statements"),  copies of which are  included  in
Schedule  2.04(a).  The  Financial  Statements  fairly  present in all  material
respects the financial  position and the results of operations and cash flows of
the Company,  for the respective dates or periods (as the case may be) indicated
therein and have been prepared in conformity  with GAAP,  except for the absence
of footnotes  and normal  year-end  adjustments  with  respect to the  unaudited
statements. All of the assets, liabilities, income, costs and expenses reflected
in the  Financial  Statements  are related to the  Business and arose out of and
were  incurred  in the  ordinary  course  of the  Business.  All  related  party
transactions  have been accounted for by use of consistent  accounting  policies

                                       10
<PAGE>

and  methodologies  that would not affect the  comparability  of such  financial
information in any material way.

                  (b)  Except  as   specifically   reflected  in  the  Financial
Statements or Schedule  2.04(b) or elsewhere in the Schedules or as contemplated
by this  Agreement,  the Company does not have any  liabilities,  commitments or
obligations  of any kind  whatsoever  (whether  secured or unsecured and whether
accrued, absolute,  contingent, direct, indirect or otherwise) that are required
to be  reflected  in the  Financial  Statements,  other  than  any  liabilities,
commitments or obligations  incurred after June 30, 2000 in the ordinary  course
of business.

                  (c)  The   Stockholders   have  delivered  to  Buyers  certain
financial  information  with  regard to future  sales,  earnings as set forth in
Schedule 2.04 (c). The projections  are based on assumptions  that the Principal
Stockholders believed were reasonable based on the facts and circumstances known
to  them as of the  date  of  such  projections;  provided  that  the  Principal
Stockholders make no representations or warranties  regarding whether or not the
results of operations  actually  experienced  by the Surviving  Company shall be
consistent with or similar to such projections.

            2.05.  Absence of Certain Changes or Events.  Except as set forth in
Schedule  2.05 or reflected  in the June 30, 2000 Balance  Sheet or permitted or
contemplated  by this  Agreement,  since June 30, 2000,  the Company has not (a)
suffered  any  material  damage,  destruction  or casualty  loss to its physical
properties;  (b) incurred or discharged any material  obligation or liability or
entered into any other  material  transaction  except in the ordinary  course of
business;  (c) suffered any material  adverse change in the business,  financial
condition,  assets,  liabilities,  operations  or results of  operations  of the
Company;  (d) increased the rate or terms of  compensation  payable or to become
payable by the Company to its directors,  officers or key employees or increased
the rate or terms of any bonus,  pension or other employee benefit plan covering
any of its directors,  officers or key employees,  except in each case increases
occurring in the ordinary  course of business in  accordance  with its customary
practices   (including   normal   periodic   performance   reviews  and  related
compensation  and  benefit   increases)  or  as  required  by  any  pre-existing
Commitment   identified  in  Schedule  2.08;  (e)  consummated,   or  agreed  to
consummate,  any sale,  lease or other transfer or disposition of any properties
or  assets,  except  for the sale of  inventory  items or  licensing  or sale of
software  in the  ordinary  course of  business  and  except for the sale of any
tangible personal property that, in the reasonable judgment of the Company,  has
become uneconomic, obsolete or worn out; (f) incurred, assumed or guaranteed any
indebtedness  for borrowed  money;  (g) granted any  mortgage,  pledge,  lien or
encumbrance  on any of its  material  properties  or assets;  (h) entered  into,
amended or terminated  any material  Commitment,  or waived any material  rights
thereunder  except in the ordinary course of business;  or (i) made any grant of
credit to any customer or  distributor  on terms or in amounts  materially  more
favorable  than those that have been extended to such customer or distributor in
the past.  Since June 30,  2000,  the Company has been  operated in all material
respects in the ordinary course in a manner consistent with past practice.

            2.06. Assets and Properties.

                  (a) The Company has good title to all of the material tangible
personal  assets  and  properties  which it  purports  to own  (including  those

                                       11
<PAGE>

reflected on the June 30, 2000 Balance  Sheet,  except for assets and properties
sold, consumed or otherwise disposed of in the ordinary course of business since
the date of the Balance Sheet,  which are not  individually  or in the aggregate
material),  free  and  clear of all  Encumbrances,  except  (a) as set  forth in
Schedule 2.06(a), and (b) liens for taxes not yet due and payable or due but not
delinquent or being contested in good faith by appropriate  proceedings.  Except
as set forth in  Schedule  2.06(a),  the assets  owned or leased by the  Company
constitute  all the assets  used in and  necessary  to conduct  the  Business as

reserve as of the  Closing  Date which will be based on the reserve set forth on
the June 30, 2000 Balance  Sheet,  as adjusted for the Company's  operations and
transactions  through the Closing Date,  calculated in accordance  with the past
custom and practice of the Company in preparing its financial statements and Tax
Returns.  All Taxes  required to be withheld and paid over by the Company to any
relevant taxing authority in connection with payments to employees,  independent

deficiencies for any Tax have been threatened, proposed, asserted or assessed in
writing  against the Company  that have not been  satisfied;  (iii) no audits or

the Company for any period (or portion of a period) after the Closing;  and (vi)
no power of attorney  has been granted by the Company with respect to any matter
relating to Taxes of the Company that is currently in force.

                  (c) The  Company  is not a party to or  liable  under  any Tax
Sharing Agreement with respect to Taxes of any consolidated, combined or unitary
group  other  than the  consolidated,  combined  or  unitary  group of which the
Company is  presently  a member.  Except as set forth in Schedule  2.14(c),  the
Company has not,  with  respect to any taxable  period for which the  applicable
statute of limitations  has not run, filed a combined,  consolidated  or unitary
Tax Return with respect to any affiliated  group.  Schedule 2.14(c) sets forth a
complete  list  of  all  states,  territories  and  jurisdictions  (foreign  and
domestic) in which the Company has filed Income Tax Returns for taxable  periods
ending on or after  December 31, 1994. The Company will not, in the absence of a
closing agreement provided for in the Treasury Regulations under Section 1503 of
the Code,  trigger the recapture of any dual consolidated  losses (as defined in

and (2),  shall,  to the extent not otherwise  required by law, be prepared in a
manner consistent with the Company's (as appropriate)  past practice  (including
any Tax  elections  and methods of  accounting).  With respect to any Tax Return

return  shall  provide  the  other  party a draft  of such  Tax  Return  and Tax
information  (including,  without  limitation,  work papers and  schedules)  for
review of such Tax  Return in a timely  manner no later  than  thirty  (30) days
prior to the due date (taking into account valid  extensions)  for the filing of
such Tax Return. The parties shall consult in good faith with regard to the form
and content of such Returns,  provided  that, in the event of any  disagreement,
the  Returns   shall  be  filed  in  the  form  set  forth  by  the  party  with
responsibility for the preparation of the Return set forth in Section 4.05.

                  (c) Termination of Tax Sharing Agreements; Powers of Attorney.

                      (1) Any Tax  Sharing  Agreement  to which the Company is a
party shall be terminated as of the Closing Date,  and the Company shall have no
further obligations  thereunder.  For purposes of this Agreement,  the term "Tax
Sharing  Agreement"  includes  any  agreement  or  arrangement,  whether  or not
written,  providing  for the sharing or allocation of liability for Taxes of the
parties thereto.

                      (2) All powers of  attorney  granted by the  Company  with
respect to Taxes shall be revoked as of the Closing Date.

                      (3)  Between  the date of this  Agreement  and the Closing
Date,  the  Principal  Stockholders  will not cause or permit the Company to (i)
make any change in the Company's Tax accounting  methods,  any new election with
respect to Taxes or any modification or revocation of any existing election with
respect to Taxes or (ii) settle or otherwise dispose of any Tax audit,  dispute,
or other Tax  proceeding,  in each case  without ADS'  express  written  consent
thereto, which consent shall not be unreasonably withheld or delayed.

                  (d) Assistance and Cooperation.

                      (1)  From  and  after  the  Closing  Date,  to the  extent
reasonably  requested  by the other  party,  the  Stockholders  and Buyers shall
assist and cooperate with each other in the  preparation of any Tax Return which
the other party is  responsible  to file pursuant to Section  4.05(b) herein and
shall assist and  cooperate  with the other party in preparing for any audits or
disputes relating to Taxes for which the other party is responsible  pursuant to
this  Agreement.  From and after the Closing Date, the  Stockholders  and Buyers
shall,  pursuant to the other party's reasonable request,  make available to the
other party all information,  records and documents reasonably available to that
party which are necessary for the preparation of any Tax Return or resolution of
any audit or  dispute.  In all such  cases,  the  party  seeking  assistance  or
cooperation  shall bear the expenses of the other party  incurred in  connection
with respect thereto.

                      (2) From and after the Closing Date, the  Stockholders and
Buyers  shall  provide  timely  notice to the other in writing of any pending or
threatened  tax audits or  assessments  of the Company  for taxable  periods for
which the other is liable under this Agreement, and shall furnish the other with
copies of all  correspondence  received from any taxing  authority in connection
with any tax audit or  information  request  with  respect  to any such  taxable
period.

                  (e) Certain  Taxes.  The  Stockholders  shall bear,  and shall
indemnify and hold harmless Buyers and their affiliates (including the Surviving
Company) from and against, all sales, transfer, stamp, documentary,  real estate
transfer, real estate gains, and other similar Taxes incurred in connection with
the transactions contemplated by this Agreement. The Stockholders shall file, on
a timely basis,  any Returns required to be filed in connection with such Taxes,
and Buyers shall cooperate with Stockholders in such preparation.

                  (f) Contests.

                      (1) Subject to the provisions of this Section 4.05(f), the
Stockholders shall have the right, at their own expense, to control,  manage and
be responsible  for any audit,  contest,  or similar  proceeding with respect to
Taxes for any Taxable  year or period  ending on or before the Closing  Date and
shall have the right to settle or contest in their  discretion  any such  audit,
contest or proceeding;  provided,  however,  that (i) the Stockholders shall not
have the right to control any such proceeding  unless they first  acknowledge in
writing their obligation to fully indemnify Buyers for the Taxes at issue in the
proceeding;  (ii) no  settlement  or  disposition  of any such  proceeding  or a
proceeding  described  in clause  (iii) of this  paragraph  shall be made by one
party without the other party's consent (which consent shall not be unreasonably
withheld or delayed) if the same  reasonably  could be expected to affect either
Buyers'  liability for Tax in any taxable  period or portion of a taxable period
ending  after the Closing  Date or the  Stockholders'  liability  under  Section
4.05(a);  and (iii) Buyers or the Stockholders  shall control any Tax proceeding
relating to a taxable  period that begins  before,  and ends after,  the Closing
Date based upon which party would bear the burden of the greater  portion of the
Tax.

                      (2)  Except  for  proceedings  the  control  of  which  is
determined  pursuant to Section  4.05(f)(1)  above,  Buyers shall,  at their own


                                       26
<PAGE>

expense,  control,  manage and  solely be  responsible  for any audit,  contest,
claim,  proceeding  or inquiry with respect to Income Taxes for any Taxable year
or period  beginning  after the Closing Date, and shall have the exclusive right
to settle or contest  any such  audit,  contest,  claim,  proceeding  or inquiry
without the consent of the Stockholders  unless such settlement or contest could
result in a liability by the Stockholders under this Agreement.

            4.06. Cooperation  with Public Filings.  The Principal  Stockholders
shall  reasonably  cooperate  with ADS and its  affiliates  and  advisors in the
preparation and filing of any public filings (and any related  documentation  or
filings) in a timely  fashion  and shall use their  reasonable  best  efforts to
assist  ADS in having  any  registration  statement  declared  effective  by the
Commission as promptly as practicable  and in maintaining the  effectiveness  of
any such  registration  statement,  in all cases at the sole cost and expense of
ADS.

            4.07. Tax Reorganization.

                  (a) Each  party to this  Agreement  hereby  agrees to take all
reasonable actions to cause the Merger to qualify as a reorganization within the
meaning of Section  368(a) of the Code and will  immediately  notify each of the
other parties of any  circumstance  or condition of which it is or becomes aware
of which might cause the Merger to fail to so qualify. The Buyers represent that
they have not taken any action that would cause the Merger to fail to so qualify
as a  reorganization  within the meaning of Section  368(a) of the Code, and are
not  aware of any  circumstances  which  would  cause  the  Merger to fail to so
qualify. In support of the qualification of the transaction  thereunder,  Buyers
further represent that on the Closing Date:

                      (1) None of the  Buyers has any plan or  intention  (A) to
cause  the  Surviving  Company  to  sell  or  dispose  of any of the  assets  or
properties of the Company  acquired in the Merger except for dispositions in the
ordinary   course  of   business  or   transfers   permitted   by  Treas.   Reg.
ss.1.368-2(k)(1),  (B) to  liquidate  the  Surviving  Company,  (C) to merge the
Surviving Company with or into another corporation or corporations,  (D) to sell
or otherwise dispose of the stock of the Surviving Company,  or (E) to cause the
Surviving  Corporation to issue additional  shares of stock that would result in
Buyer  losing  "control"  (within the meaning of Section 368 of the Code) of the
Surviving Company.

                      (2) The Buyers  intend to cause the  Surviving  Company to
continue a historic business of the Company or use a significant  portion of the
Company's  historic  business  assets in a business within the meaning of Treas.
Reg.ss.1.368-1(d).

                      (3)  None of the  Buyers  has any  plan  or  intention  to
reacquire  any of the ADS Common  Stock  except as  modifications  to the Merger
Consideration  provided herein issued in the Merger pursuant to the True-up, and
no  person   related  to  the  Buyers   within  the   meaning  of  Treas.   Reg.
ss.1.368-1(e)(3)  and no person acting as an  intermediary  for Buyers or such a
related  person has a plan or  intention  to acquire any of the ADS Common Stock
issued in the Merger.

                      (4) Immediately  prior to the Merger,  ADS will own all of
the outstanding stock of PDS Acquisition.


                                       27
<PAGE>

                      (5) Except for obligations incurred in connection with its
incorporation  or  organization  or the  negotiation  and  consummation  of this
Agreement and the transactions  contemplated hereby, PDS Acquisition has neither
incurred any  obligation or liability nor engaged in any business or activity of
any type or kind  whatsoever or entered into any agreement or  arrangement  with
any person.

                      (6) PDS Acquisition is a direct subsidiary of ADS.

                  (b) Buyers agree that they will not take any action,  and will
not cause the Surviving Company to take any action, which would cause the Merger
to fail to qualify as a  reorganization  within the meaning of Section 368(a) of
the Code. Buyers shall report the Merger as a reorganization  within the meaning
of Section  368(a) of the Code for all purposes,  including  Federal  income tax
reporting purposes.

            4.08. Stockholders' Representative.

                  (a) Upon the  Effective  Time and  without  further act of any
Stockholder,  Vasa (the  "Stockholders'  Representative")  shall be appointed as
agent and attorney-in-fact for each Stockholder,  for and on behalf of each such
Stockholder, with full power of substitution,  and with full power and authority
to represent the  Stockholders  and their successors with respect to all matters
arising  under  this  Agreement,  and all  actions  taken  by the  Stockholders'
Representative  hereunder  shall be  binding  upon such  Stockholders  and their
successors  as if expressly  ratified and  confirmed in writing by each of them.
Without   limiting  the   generality  of  the   foregoing,   the   Stockholders'
Representative  shall  have  full  power  and  authority,  on  behalf of all the
Stockholders and their successors,  to interpret all the terms and provisions of
this Agreement,  to dispute or fail to dispute any "Claim of Damages" made by an
Indemnified  Party, to assert Claims of Damages against any Indemnifying  Party,
to negotiate and compromise any dispute which may arise under this Agreement, to
sign any releases or other  documents  with respect to any such dispute,  and to
authorize delivery of any payments to be made with respect thereto.

                  (b)  The  Stockholders'   Representative,   or  any  successor
hereafter appointed,  may resign and shall be discharged of his duties hereunder
upon the appointment of a successor Stockholders'  Representative as hereinafter
provided. In case of such resignation, or in the event of the death or inability
to act of the  Representative,  a successor shall be named in accordance with an
agreement  by  and  between  the   Stockholders   of  even  date  herewith  (the
"Stockholders'  Agreement").  Each such successor  Stockholders'  Representative
shall have all the power, authority, rights and privileges hereby conferred upon
the  original   Stockholders'   Representative,   and  the  term  "Stockholders'
Representative"  as used  herein  shall be  deemed  to  include  such  successor
Stockholders' Representative.

                  (c) In performing any of his duties under this  Agreement,  or
upon the claimed  failure to perform  his duties  hereunder,  the  Stockholders'
Representative  shall not be liable to the  Stockholders  or anyone else for any

                                       28
<PAGE>

damages,  losses or  expenses  which  they may incur as a result of any act,  or
failure to act under this Agreement;  provided,  however, that the Stockholders'
Representative  shall be liable for damages  arising out of actions or omissions
that both (i) were  taken or  omitted  not in good  faith  and (ii)  constituted
willful  default or gross  negligence  under this  Agreement.  Accordingly,  the
Stockholders'  Representative shall not incur any such liability with respect to
(i) any action  taken or  omitted  to be taken in good faith upon  advice of his
counsel  given  with  respect  to  any  questions  relating  to the  duties  and
responsibilities  of the  Stockholders'  Representative  hereunder;  or (ii) any
action taken or omitted to be taken in reliance upon any document, including any
written notice or instructions  provided for in this  Agreement,  not only as to
its due execution and to the validity and  effectiveness of its provisions,  but
also as to the truth and accuracy of any information  contained  therein,  which
the Stockholders'  Representative  shall in good faith believe to be genuine, to
have been signed or presented by the  purported  proper person or persons and to
conform with the  provisions  of this  Agreement.  The  limitation  of liability
provisions of this Section shall survive the  termination  of this Agreement and
the resignation of the  Stockholders'  Representative.  The  Stockholders  shall
severally  indemnify  the  Stockholders'  Representative  and hold him  harmless
against any loss,  liability or expense (including any expenses of legal counsel
retained by the Stockholders'  Representative) incurred without willful default,
gross  negligence or bad faith on the part of the  Stockholders'  Representative
and arising out of or in connection with the acceptance or administration of his
duties hereunder.

            4.09.  Disclosure  Information.  The Stockholders shall allow ADS to
review  all  disclosure  materials  prior to such  materials  being  sent to the
Stockholders  of the  Company and shall  allow ADS to amend or  supplement  such
materials so as to comply with the Securities Act (as  hereinafter  defined) and
the securities laws of all applicable states.

            4.10. Certain Matters With Respect to Employees.

                  (a) Following  consummation of the Merger, ADS shall cause all
employees of the Company  prior to  consummation  of the Merger  initially to be
retained  following the Merger.  The terms and  conditions of employment for all
employees  will be  substantially  similar to the terms and  conditions of their
employment prior to the Merger,  including but not limited to the following: (i)
employees  shall  maintain  credit for accrued but unused  vacation  time;  (ii)
employees will participate on the same basis as similarly situated ADS employees
and maintain  credit for prior years of service with the Company for purposes of
determining  vacation time and other employee  benefits with respect to benefits
offered  by  the  Surviving   Company;   and  (iii)  except  for  the  Principal
Stockholders,  maintain the salary of the employees of the Surviving  Company at
an amount not less than his or her salary prior to the Effective Time.

                  (b) Following  consummation of the Merger,  ADS will cause the
Surviving  Company to provide  fringe  benefits  (including  but not  limited to
health and  disability  insurance  and other group  insurance  policies)  to its
employees at a level substantially  similar to the level provided by the Company
prior to the  transaction,  unless ADS  provides  benefits to its  employees  on
better terms or in greater amounts, in which case the employees of the Surviving
Company  will be  entitled  to  such  greater  benefits.  If ADS  determines  to
discontinue  policies and plans  maintained by the Company and to include all or
any part of the employees of the Company in group insurance  coverages  provided


                                       29
<PAGE>

through ADS, ADS shall use its best efforts to cause such new coverages, insofar
as they relate to former employees of the Company,  not to exclude  pre-existing
conditions.

            4.11. Post-Closing Operations. Provided and as long as the Surviving
Company is meeting or exceeding its Projected EBITDA Amounts, ADS agrees that it
shall not except as provided herein  restrict the Surviving  Company from making
its best efforts to maximize,  to the extent  reasonable  in the exercise of its
sound business judgment,  EBITDA of the Surviving Company through the end of the
Second Earnout Period. In connection with the foregoing,  the Board of Directors
of the  Surviving  Company  and ADS will take no  action  that has as one of its
purposes or objectives  the reduction of EBITDA of the Surviving  Company during
such periods.  With respect to operational  decisions and actions,  the Board of
Directors of the Surviving Company and ADS will give good faith consideration to
the impact of such decisions on the earnout payments.

            4.12. ADS Stock Options. Promptly after the Closing Date (but in any
event within thirty (30) days of the Closing Date), ADS will grant stock options
to purchase  100,000  shares of its ADS Stock to the  employees of the Surviving
Company  pursuant to a Stock Option  Agreement in the form set forth in Schedule
4.12(a).  The  persons to whom such  options  shall be granted and the number of
options to be granted to each person shall be  determined  by the  Stockholders'
Representative  at his discretion.  The exercise of such stock options shall not
be charged against Stockholder's EBITDA in any manner.

exemption therefrom.

                                  ARTICLE VIII

                          TERMINATION PRIOR TO CLOSING

            8.01.  Termination.  This Agreement may be terminated and the Merger
abandoned  at any time  prior to the  Effective  Time,  whether  before or after
approval of the Merger by the Stockholders:

                  (a) by mutual written consent of the Company and ADS;

                  (b) by either ADS or the  Company if: (i) the  Effective  Time
has not occurred by October 27, 2000  (provided that the right to terminate this
Agreement under this clause 8.01(b)(i) shall not be available to any party whose
failure to fulfill any  obligation  hereunder has been the cause of, or resulted
in, the failure of the Effective Time to occur on or before such date); (ii) any
"Governmental Authority", the consent of which is a condition to the obligations
of ADS and Company to consummate the Merger,  shall have determined not to grant
its consent and all appeals of such determination shall have been taken and have
been  unsuccessful;  or (iii) there shall be any statute,  rule,  regulation  or


                                       33
<PAGE>

order enacted,  promulgated or issued or deemed  applicable to the Merger by any
"Governmental Entity" that would make consummation of the Merger illegal;

                  (c) by either  the  Company  or ADS if a  Governmental  Entity
shall  have  issued an order,  decree  or ruling or taken any other  action  (an
"Order"), in any case having the effect of permanently restraining, enjoining or
otherwise prohibiting the Merger, which Order is final and nonappealable;

                  (d) by either the Company or ADS if the  required  approval of
the Stockholders  contemplated by this Agreement shall not have been obtained by
reason of the  failure to obtain  the  required  vote or written  consent of the
Stockholders  (provided that the right to terminate  this  Agreement  under this
Section  8.01(d)  shall not be  available  to the  Company  where the failure to
obtain  the  Stockholders'  approval  shall  have been  caused by the  action or
failure to act of the Company in breach of this Agreement);

                  (e) by ADS if there shall be any action taken, or any statute,
rule, regulation or order enacted, promulgated or issued or deemed applicable to
the Merger,  by any Governmental  Entity,  which would: (i) prohibit ADS' or the
Company's  ownership  or operation of any portion of the business of the Company
or (ii) compel ADS or the Company to dispose of or hold separate, as a result of
the Merger, any portion of the business or assets of the Company or ADS;

                  (f) by the  Company  if it is not in  material  breach  of its
obligations   under  this   Agreement  and  there  has  been  a  breach  of  any
representation,  warranty, covenant or agreement on the part of ADS set forth in
this Agreement,  or if any  representation  or warranty of ADS shall have become
untrue,  in either case such that the conditions set forth in Section 6.01 would
not then be satisfied; provided that if such inaccuracy in ADS's representations
and  warranties  or breach by ADS is curable by ADS through the  exercise of its
commercially  reasonable  efforts,  then the  Company  may only  terminate  this
Agreement  under this Section  8.01(f) if the breach is not cured within 10 days
following  the date of written  notice from  Company of such breach (but no cure
period shall be required for a breach which by its nature cannot be cured); or

                  (g) by ADS if it is not in material  breach of its obligations
under  this  Agreement  and  there  has  been a  breach  of any  representation,
warranty,  covenant  or  agreement  on the part of the Company set forth in this
Agreement, or if any representation or warranty of the Company shall have become
untrue,  in either case such that the conditions set forth in Section 5.01 would
not  then  be  satisfied;   provided,  that  if  such  inaccuracy  in  Company's
representations  and  warranties  or breach by  Company  is  curable  by Company
through the exercise of its commercially  reasonable efforts,  then ADS may only
terminate this Agreement  under this Section  8.01(g) if the breach is not cured
within 10 days the date of written  notice  from ADS of such breach (but no cure
period shall be required for a breach which by its nature cannot be cured).

            Where action is taken to terminate this  Agreement  pursuant to this
Section  8.01,  it shall be  sufficient  for such action to be authorized by the
Board of Directors (as applicable) of the party taking such action.

            8.02.  Effect of  Termination.  In the event of  termination of this
Agreement as provided in Section 8.01,  this Agreement  shall  forthwith  become
void and there  shall be no  liability  or  obligation  on the part of ADS,  PDS
Acquisition  or  the  Company,  or  their  respective  officers,   directors  or
stockholders;  provided  that, the provisions of Sections 4.03 and Article IX of
this Agreement shall remain in full force and effect and survive any termination
of this Agreement.

            8.03.  Amendment.  Except as is otherwise required by applicable law
after the Stockholders approve this Agreement,  this Agreement may be amended by
the parties  hereto at any time only by  execution of an  instrument  in writing
signed on behalf of each of the parties hereto,  except that following  approval
by the  Stockholders  there shall be no  amendment  or  supplement  which by law
requires further  approval by the Stockholders  without such further approval by
the Stockholders.

            8.04.  Extension;  Waiver.  At any time prior to the Effective Time,
ADS and PDS Acquisition, on the one hand, and the Company, on the other, may, to
the extent legally  allowed,  (i) extend the time for the  performance of any of
the  obligations of the other party hereto,  (ii) waive any  inaccuracies in the
representations  and warranties  made to such party  contained  herein or in any
document  delivered  pursuant hereto, and (iii) waive compliance with any of the
agreements or conditions  for the benefit of such party  contained  herein.  Any
agreement on the part of a party hereto to any such extension or waiver shall be
valid only if set forth in an  instrument  in  writing  signed on behalf of such
party.

                                   ARTICLE IX

                                  MISCELLANEOUS

            9.01.  Survival.  The  representations and warranties of the parties
hereto  contained  herein  or  in  any  agreement,  certificate  (including  the
Principal  Stockholders'  Certificate  and the  Buyers'  Certificate)  or  other
document  executed  at or  prior  to the  Closing  in  connection  herewith  (an
"Ancillary  Document")  shall expire on the 18-month  anniversary  of the Merger
Date, except that the representations and warranties set forth in Sections 2.01,
2.07,  2.12 and 2.14 of this Agreement  shall survive the Closing Date until the
expiration of the applicable  statute of  limitations  (including any extensions
thereof).  After the  expiration  of such  periods,  any claim by a party hereto
based upon any such  representation or warranty shall be of no further force and
effect,  except to the extent a party has  asserted a claim in  accordance  with
this Article IX for breach of any such  representation  or warranty prior to the
expiration  of such  period,  in which event any  representation  or warranty to
which such claim  relates  shall  survive  with respect to such claim until such
claim is resolved as provided in this Article IX. The covenants  and  agreements
of the parties  hereto shall survive the Closing  until  performed in accordance
with their terms.

            9.02. Agreement to Indemnify.

                  (a) From and after the Closing Date,  Buyers shall  indemnify,
defend and hold harmless Stockholders and any affiliate of Stockholders and each


                                       35
<PAGE>

of Stockholders' respective agents and representatives, and Stockholders' heirs,
executors,  successors  and assigns  (collectively,  "Stockholders'  Indemnified
Group")  from  and  against  any  liability,   loss,  damage,  claim  (including
third-party  claims,  whether or not meritorious),  cost or expense  (including,
without limitation, reasonable attorneys' fees and disbursements) (collectively,
"Losses") incurred or suffered by Stockholders'  Indemnified Group to the extent
the Losses arise out of, or result from (i) the failure of any representation or
warranty made by Buyers  herein or in any  Ancillary  Document to have been true
when made and as of the  Closing  Date,  or (ii) the breach of any  covenant  or
agreement of Buyers contained herein or in any Ancillary Document.

                  (b)  From  and  after  the   Closing   Date,   the   Principal
Stockholders shall indemnify,  defend and hold harmless Buyers and any affiliate
of Buyers and each of their respective directors,  officers,  employees,  agents
and representatives, and each of the heirs, executors, successors and assigns of
any of the  foregoing  (collectively,  "Buyers'  Indemnified  Group")  from  and
against all Losses  incurred or  suffered  by Buyers'  Indemnified  Group to the
extent  the  Losses  arise  out  of,  or  result  from  (i) the  failure  of any
representation or warranty made by the Principal  Stockholders  herein or in any
Ancillary  Document to have been true when made and as of the Closing  Date,  or
(ii) the breach of any  covenant  or  agreement  of the  Principal  Stockholders
contained herein or in any Ancillary Document.

            9.03. Indemnification Procedure.

                  (a) The party  seeking  indemnification  under this  Agreement
(the   "Indemnified   Party")  shall  promptly   notify  the  party  from  which
indemnification  is being  sought  (the  "Indemnifying  Party") of the facts and
circumstances  upon  which the  Indemnified  Party  intends  to base a claim for
indemnification  hereunder  ("Indemnification   Notices").  The  Indemnification
Notice  shall in all events be  considered  prompt if given (a) no later than 30
days after the  Indemnified  Party  learns of the facts upon which it will claim
such  indemnification  or (b) if  earlier,  in  sufficient  time  to  allow  the
Indemnifying  Party to  exercise  its  rights  pursuant  to this  Section  9.03;
provided,  however,  that the failure to provide such Notice of claims  promptly
(so long as a notice of claims is given before the date on which the  applicable
representation  or warranty  ceases to survive) shall not affect the obligations
of the Indemnifying  Party hereunder except to the extent the Indemnifying Party
is prejudiced  thereby.  The Indemnifying Party shall have the right, at its own
cost, to participate  jointly in the defense of any third-party  claim,  demand,
lawsuit or other  proceeding in connection with which the Indemnified  Party has
claimed  indemnification  hereunder,  and may elect to take over the  defense of
such claim within 10 days following  notice  thereof;  provided,  however,  that
Stockholders  shall  not be  permitted  to take  over the  defense  of any claim
brought by any  customer  or  supplier  of the  Business  against  any member of
Buyers'  Indemnified Group for which  indemnification  is available  pursuant to
this Article IX, and such member of Buyers'  Indemnified Group shall defend such
claim; provided,  further, that no member of Buyers' Indemnified Group shall not
settle  or  otherwise   dispose  of  any  claim   without  the  consent  of  the
Stockholders'  Representative,  which consent shall not be unreasonably withheld
or delayed. If the Indemnifying Party makes such an election,  (x) it shall keep
the  Indemnified  Party  informed  as to the  status  of such  matter  and shall
promptly send copies of all pleadings to the Indemnified Party, (y) with respect
to any issue involved in such claim, it shall have the sole right,  with respect


                                       36
<PAGE>

to claims or portions of claims  seeking  monetary  damages  only,  to settle or
otherwise  dispose of such  claim on such  terms as it, in its sole  discretion,
shall deem appropriate;  provided,  however, that the consent of the Indemnified
Party to the settlement or disposition  shall be required if such  settlement or
disposition  shall  result in any  liability  to,  equitable  relief  against or
adverse  business  effect on the Indemnified  Party,  which consent shall not be
unreasonably  withheld or delayed,  and (z) the Indemnified Party shall have the
right to  participate  jointly in the defense of such claim,  but shall do so at
its  own  cost  not  subject  to  reimbursement   under  Section  9.02.  If  the
Indemnifying  Party  does not elect to take over the  defense  of a  third-party
claim,  the  Indemnified  Party shall have the right to contest,  compromise  or
settle such claim in the exercise of its reasonable judgment; provided, however,
that the consent of the  Indemnifying  Party to any  compromise or settlement of
such claim shall be required if such  compromise or  settlement  shall result in
any liability to the Indemnifying Party, which consent shall not be unreasonably
withheld or delayed.

                  (b)  Notwithstanding  the provisions of Section 9.03(a),  with
respect  to any  third-party  claim or  demand  that the  Indemnifying  Party is
defending, the Indemnified Party shall have the right to retain separate counsel
to  represent it and the  Indemnifying  Party shall pay the fees and expenses of
such  separate   counsel  if  there  are  conflicts  of  interest   between  the
Indemnifying  Party and Indemnified Party that make it reasonably  necessary for
separate counsel to represent the Indemnified Party and the Indemnifying Party.

            9.04. Other Indemnification Matters.

                  (a) The  indemnification  provided in this Article IX shall be
the  sole  and   exclusive   remedy  for  any   inaccuracy   or  breach  of  any
representation,  warranty or  covenant  made by  Stockholders  or Buyers in this
Agreement or in any Ancillary  Document (except that the  Stockholders  shall be
entitled to specific  performance and other equitable relief with respect to any
breach by ADS under the Registration  Rights Agreement).  All amounts payable by
one party in indemnification of the other (whether or not as provided in Section
9.04(d)) shall be considered an adjustment to the Merger Consideration.

                  (b) Upon  making any payment to an  Indemnified  Party for any
indemnification  claim pursuant to this Article IX, the Indemnifying Party shall
be  subrogated,  to the  extent  of  such  payment,  to  any  rights  which  the
Indemnified Party may have against any other parties with respect to the subject
matter underlying such indemnification claim.

                  (c) The  amount of any  Losses  shall be  computed  net of any
insurance  proceeds,  tax benefits and recoveries  from third parties other than
insurance   proceeds  (whether   pursuant  to  cross-claims,   counterclaims  or
otherwise) received by the Indemnitee or its affiliates in connection therewith.

                  (d)  Notwithstanding  anything  herein  to  the  contrary,  if
Principal  Stockholders shall have a payment obligation pursuant to this Article
IX, the Principal  Stockholders  may, at their option,  (i) make such payment in
cash by wire transfer of  immediately  available  funds,  (ii) reduce any future
payment   obligation   to   Stockholders   pursuant   to   Section   1.05  on  a

                                       37
<PAGE>

dollar-for-dollar  basis,  or (iii) if ADS is in possession  of any  certificate
representing  shares of ADS Stock issued pursuant to Section 1.05(a),  allow ADS
to take back the  number of shares  represented  by such  certificate  having an
aggregate market value equal to the indemnification  obligation of Stockholders.
For purposes of clause (iii) above,  "market  value" for a share of common stock
of ADS shall be the average  closing  price per share of common stock of ADS for
the 20 trading days  immediately  preceding  the date on which ADS reclaims such
shares.  If any future payment  obligation  pursuant to Section 1.05(a) shall be
reduced  pursuant to clause (ii)  above,  the amount so reduced  shall be deemed
"paid" for purposes of Section 1.05.

                  (e) Notwithstanding anything to the contrary contained herein,
no claim shall be asserted by the  Indemnified  Party for any Losses  unless and
until  the  aggregate  of  all  Losses  incurred  by  that   Indemnified   Party
(collectively,  in the case of the Stockholders) exceeds $250,000.  Furthermore,
in  no  event  whatsoever  shall  the  aggregate  liability  of  either  of  the
Indemnified  Parties  (collectively,  in the case of the  Stockholders)  for all
Losses  exceed an aggregate of an amount equal to no more than 80% of the Merger
Consideration received or entitled to be received by the Stockholders.

            9.05. Interpretive Provisions.

                  (a)  Whenever  used  in  this  Agreement,  "to  the  Principal
Stockholders'  knowledge" or "to the  knowledge of the  Principal  Stockholders'
shall mean the actual knowledge of the Principal  Stockholders and the knowledge
that either would have after due and reasonable inquiry.

                  (b) The words "hereof," "herein," "hereby" and "hereunder" and
words of  similar  import  refer  to this  Agreement  as a whole  and not to any
particular Article, Section or other subdivision thereof.

                  (c) For  purposes  of this  Agreement,  the  Company  shall be
deemed to be an affiliate of Stockholders  prior to the Closing and an affiliate
of ADS after the Effective Time.

            9.06. Entire Agreement. This Agreement (including the Schedules) and
the Ancillary  Documents  constitute the sole  understanding of the parties with
respect to the subject matter hereof.

            9.07. Successors  and  Assigns.  The  terms and  conditions  of this
Agreement  shall  inure to the  benefit  of and be binding  upon the  respective
heirs,  successors and assigns of the parties hereto;  provided,  however,  that
this  Agreement  may not be assigned by either  party  hereto  without the prior
written  consent of the other  (except that Buyers may without the prior written
consent of Stockholders assign this Agreement to any affiliate of Buyers so long
as such assignee shall execute a counterpart  of this  Agreement  agreeing to be
bound by the  provisions  hereof as  "Buyers,"  and  agreeing  to be jointly and
severally  liable  with  the  assignor  and any  other  assignee  for all of the
obligations of the assignor hereunder), but no such assignment of this Agreement
or any of the  rights  or  obligations  hereunder  shall  relieve  Buyers of its
obligations  under this Agreement.  Notwithstanding  anything  contained in this

                                       38
<PAGE>

Agreement to the contrary,  nothing in this  Agreement,  express or implied,  is
intended  to  confer  on any  person  other  than the  parties  hereto  or their
respective heirs, successors, executors,  administrators and assigns any rights,
remedies, obligations or liabilities under or by reason of this Agreement.

            9.08.  Headings.   The  headings  of  the  Articles,   Sections  and
paragraphs of this Agreement are inserted for convenience  only and shall not be
deemed  to  constitute  part of this  Agreement  or to affect  the  construction
hereof.

            9.09.  Modification  and  Waiver.  No  amendment,   modification  or
alteration of the terms or provisions of this Agreement  shall be binding unless
the same shall be in writing and duly  executed by the  parties  hereto,  except
that any of the terms or provisions  of this  Agreement may be waived in writing
at any time by the party which is entitled to the  benefits of such waived terms
or provisions.  No waiver of any of the  provisions of this  Agreement  shall be
deemed to or shall constitute a waiver of any other provision hereof (whether or
not similar).  No delay on the part of any party in exercising any right,  power
or privilege hereunder shall operate as a waiver thereof.

            9.10.  Counterparts.  This  Agreement may be executed in one or more
counterparts,  each of which shall for all  purposes be deemed to be an original
and all of which shall constitute the same instrument.

            9.11. Expenses. Except as otherwise provided herein, the Company and
Buyers  shall pay all costs and  expenses  incurred by them or it or on their or
its behalf in connection with this Agreement and the  transactions  contemplated
hereby,  including,  without limiting the generality of the foregoing,  fees and
expenses of their respective financial consultants, accountants and counsel.

            9.12. Notices. Any notice, request, instruction or other document to
be given  hereunder  by any party  hereto to any other party shall be in writing
and shall be given (and will be deemed to have been duly given upon  receipt) by

if such void, illegal or unenforceable  provision never comprised a part hereof,
and the remaining  provisions of this  Agreement  shall remain in full force and
effect  and  shall  not  be  affected  in  any  way  by  the  void,  illegal  or
unenforceable  provision or by its severance herefrom.  Furthermore,  in lieu of
such  severed  provision,  there  shall be added  automatically  as part of this
Agreement a provision as similar in its terms to such  severed  provision as may
be possible and be valid, legal and enforceable.
