                  (a)  Subject  to the  procedures  set  forth and  adjusted  in
accordance with the provisions of Section 2.6, below, the Buyer shall pay to the
Seller (by delivery of cash by wire  transfer to a bank account  selected by the
Seller) the "Initial  Contingent  Purchase  Price,"  which shall be equal to the
product of seven and one-half (7.5) multiplied by any excess of Initial Earn Out
Period  EBITDA  over $4.1  million the (the  "Initial  Product"),  such  Initial

Purchase  Price not paid by the Buyer when due to the Seller in accordance  with
the provisions of this Section 2.5 at the rate of the regular  commercial  prime
rate of interest of NationsBank  N.A., which NationsBank N.A. uses as a standard
for determining actual interest rates charged commercial borrowers, beginning on
the date on which  such  amount  was due to the Seller and ending on the date on
which Buyer pays such  amount to the Seller,  which  payment  shall  include any
interest accrued thereon.  The Buyer shall pay the Initial  Contingent  Purchase
Price to the  Seller  by the later of (i) 45 days  subsequent  to the end of the

concerning the calculation of the Initial Earn Out Period EBITDA.

                  (b)  Subject  to the  procedures  set  forth and  adjusted  in
accordance with the provisions of Section 2.6, below, the Buyer shall pay to the
Seller (by delivery of cash by wire  transfer to a bank account  selected by the
Seller)) the "Second  Contingent  Purchase  Price,"  which shall be equal to the
product of seven and one-half (7.5)  multiplied by any excess of Second Earn Out
Period  EBITDA over the amount of $4.7  million  (the  "Second  Product"),  such
Second  Product  being  reduced (but not below zero) by the amount of any Excess
Purchase  Price  Adjustment.  Interest shall accrue on any portion of the Second
Contingent  Purchase  Price  not paid by the  Buyer  when due to the  Seller  in
accordance  with the  provisions  of this Section 2.5 at the rate of the regular
commercial prime rate of interest of NationsBank  N.A.,  which  NationsBank N.A.

The  Preliminary  Purchase  Price  increased  by the  amount  of any  Contingent
Purchase  Price and any  Additional  Purchase Price is referred to herein as the
"Purchase Price."

         2.6 Contingent Purchase Price Determination Procedures.  Within 30 days
from the end of each of the Earn Out  Periods,  the Buyer  shall  deliver to the
Seller a draft  calculation  of either the Initial Earn Out Period EBITDA or the
Second  Earn  Out  Period  EBITDA,  as the  case  may  be,  (the  "Draft  EBITDA
Calculations")  prepared by a  nationally  recognized  accounting  firm.  If the
Seller has any  objection  to the Draft  EBITDA  Calculations,  the Seller shall
deliver a detailed  statement  describing  his objections to the Buyer within 15
days after receiving either of the Draft EBITDA Calculations.  The Buyer and the
Seller will use reasonable efforts to resolve any such objections themselves. If
the Buyer and Seller do not finally resolve any of the objections within 15 days
after the Buyer has received the statement of objections, however, the Buyer and
the Seller will  select,  within 5 days,  a  nationally  recognized  independent
accounting  firm  mutually  acceptable  to  each  party  (the  agreement  to the
selection  of which  shall not be  unreasonably  withheld)  to resolve  any such
differences  (the  "Arbitrator").  The  Arbitrator  shall  settle any  remaining
dispute by selecting the position of the party that the  Arbitrator  determines,
in its  sole  discretion,  to be the  most  correct.  The  determination  of the
Arbitrator shall be set forth in writing, delivered to each of the Buyer and the
Seller  and  shall  be  conclusive  and  binding  on the  parties  and  shall be
non-appealable.  The party whose position is not chosen by the Arbitrator  shall
pay all expenses of the Arbitrator.  The Draft EBITDA Calculations,  as adjusted
for any  items of  dispute  resolved  by the Buyer  and the  Seller  and for any
determinations  of the Arbitrator  shall  constitute the Initial Earn Out Period
EBITDA and the Second Earn Out Period EBITDA, as the case may be.

4.       REPRESENTATIONS AND WARRANTIES CONCERNING THE COMPANY.

         The Seller  represents  and  warrants to the Buyer as of the  Effective
Date and as of the Closing Date (as though made then and as though the Effective
Date were substituted for the date of this Agreement  throughout this Section 4)
as follows:

         4.1 Organization,  Qualification, and Corporate Power. The Company is a
corporation  duly organized,  validly  existing,  and in good standing under the
laws of the  jurisdiction  of its  incorporation.  As of the Closing  Date,  the
Company will be duly authorized to conduct business and will be in good standing
under the laws of each  jurisdiction  in which the  failure  to be so  qualified
would have a Material  Adverse Effect.  Schedule 4.1 lists all  jurisdictions in
which the Company is  qualified  to do business  as a foreign  corporation.  The
Company has full corporate  power and authority and all licenses,  permits,  and
authorizations  necessary to carry on the  businesses in which it is engaged and
in which it presently proposes to engage and to own and use the properties owned
and used by it.  Schedule 4.1 lists the  directors  and officers of the Company.
The Seller has delivered to the Buyer correct and complete copies of the charter
and bylaws of the Company (as amended to date). The minute books (containing the
records  of  meetings  of the  stockholders,  the  board of  directors,  and any
committees of the board of  directors),  the stock  certificate  books,  and the
stock record books of the Company are correct and  complete.  The Company is not
in default under or in violation of any provision of its charter or bylaws.

         4.2 Capitalization.  The entire authorized capital stock of the Company
consists  of 1,000  Company  Shares,  of  which  1,000  shares  are  issued  and
outstanding  and  no  shares  are  held  in  treasury.  All of  the  issued  and
outstanding Company Shares have been duly authorized,  are validly issued, fully
paid,  and  nonassessable,  and are held of record by the  Seller.  There are no
outstanding  or authorized  options,  warrants,  purchase  rights,  subscription
rights,  conversion  rights,  exchange rights, or other contracts or commitments
that could  require the Company to issue,  sell,  or  otherwise  cause to become
outstanding  any of its capital  stock.  There are no  outstanding or authorized
stock appreciation,  phantom stock, profit participation, or similar rights with
respect to the Company. There are no voting trusts, proxies, or other agreements
or  understandings  with  respect  to the  voting  of the  capital  stock of the
Company. All of the issued and outstanding Company Shares were offered,  issued,
sold and delivered by the Company in compliance with all applicable federal laws
and in material compliance with applicable state laws concerning the issuance of
securities. None of the Company Shares was issued in violation of any preemptive
rights  created by  statute,  or by the  charter  and bylaws of the  Company (as
amended to date) or by any agreement to which the Company may be bound.  Neither
the voting  stock  structure  of the Company nor the  relative  ownership of the
Company has been altered or changed in contemplation  of this Agreement.  To the
Knowledge  of the Seller,  there is no reason to believe that as a result of the
transactions  contemplated by this  Agreement,  the Buyer will not be the record
and beneficial owner of all outstanding  capital stock of the Company and rights
to acquire capital stock of the Company.

         4.3 Noncontravention.  Except as set forth on Schedule 4.3, neither the
execution  and the  delivery  of this  Agreement,  nor the  consummation  of the
transactions  contemplated  hereby,  will  (i)  conflict  with  or  violate  any
provision of the charter or bylaws of the Company as now in effect, (ii) violate

decree, ruling, charge, or other restriction of any Governmental Entity or court
to which the Company is subject or any provision of the charter or bylaws of the
Company or (iii)  conflict  with,  result in a breach of,  constitute  a default
under,  result  in the  acceleration  of,  create  in any  party  the  right  to
accelerate,  terminate,  modify,  or  cancel,  or require  any notice  under any
agreement,  contract, lease, license,  instrument, or other arrangement to which
the  Company is a party or by which it is bound or to which any of its assets is
subject (or result in the  imposition  of any Security  Interest upon any of its
assets).  Except as set forth on Schedule  4.3,  the Company is not  required to
give any notice to, make any filing with, or obtain any authorization,  consent,
or approval of any  Governmental  Entity in order for the Parties to  consummate
the transactions contemplated by this Agreement.

any Liability or obligation to pay any fees or  commissions  to any  accountant,
lawyer, broker,  finder, or agent with respect to the transactions  contemplated
by this Agreement.

valid  leasehold  interest in, the  properties and assets used by it, located on
its  premises,  shown on the Interim  Balance  Sheet or acquired  after the date
thereof,  free and  clear  of all  Security  Interests,  except  for  properties
constituting equipment furnished by Governmental Entities and property or assets
disposed of in the  Ordinary  Course of  Business  since the date of the Interim
Balance Sheet.

         4.6 Financial Statements. Except for the financial statements described
in 4.6(ii) below, which will be delivered to the Buyer on or before February 20,

Company;  and (ii) unaudited  balance sheets as of and statements of income (the

in all material  respects as of such dates and the results of  operations of the
Company for such periods, are correct and complete,  and are consistent with the
books and  records of the  Company  (which  books and  records  are  correct and
complete).

         4.7 Events  Subsequent  to the Interim  Balance  Sheet Date.  Since the
Interim  Balance Sheet Date,  there has not been any material  adverse change in
the  business,  condition  (financial  or  otherwise),  operations,  results  of

received any written notice, report or other information regarding any actual or
alleged material violation of Environmental, Health, and Safety Requirements, or
any material  liabilities or potential  material  liabilities  (whether accrued,
absolute, contingent,  unliquidated or otherwise),  including any investigatory,
remedial or corrective  obligations,  relating to the Company or its  facilities
arising under  Environmental,  Health, and Safety  Requirements,  the subject of
which would have a Material Adverse Effect on the Company.

         4.27  Subsidiaries.  The  Company  has no  subsidiaries  and  does  not
presently own, of record or  beneficially,  or control,  directly or indirectly,
any capital stock, securities convertible into capital stock or any other equity
interest in any corporation  association or business entity (except for publicly
traded  corporations  in which the Company owns less than 5% of the  outstanding
equity  interests  therein),  nor is the  Company,  directly  or  indirectly,  a
participant in any joint venture, partnership or other entity.

         4.28 Disclosure.  No  representation  or warranty made by the Seller in
this Agreement,  nor any financial statement,  certificate,  schedule or exhibit
delivered with or attached to this  Agreement and furnished by the Company,  the
Seller  or  its  representative  pursuant  hereto  or  in  connection  with  the
transaction  contemplated hereby,  contains or will contain any untrue statement
of material  fact, or omits or will omit to state a material  fact  necessary to
make the statement of facts  contained  herein or therein not  misleading in the
light of the  circumstances  under  which they were  furnished.  The  historical
information,  financial projections,  listing of Government Contract backlog and
information  concerning  Government  Contracts  relating to the Company that was
delivered  to the Buyer  prior to the date of this  Agreement  and  included  in
Schedule  4.28  ("Financial  Projections")  was  delivered  in  good  faith  and
constitutes, to the Seller's Knowledge, a good faith estimate of the information
purported  to be shown  therein.  The Seller  caused the Company to prepare such
projections  and provide such  information  in good faith based upon  reasonable
assumptions, and believes that there is a reasonable basis for such projections.
The Seller has no  Knowledge of any fact or  information  that would lead him to
believe that the Financial Projections are misleading in any material respect.

         5.5      Full Access, Confidentiality.

                  (a) The Seller  will  permit,  and the  Seller  will cause the
Company  to  permit,  representatives  of the Buyer to have  full  access at all
reasonable  times,  and in a  manner  so as not to  interfere  with  the  normal
business  operations  of the Company,  to all premises,  properties,  personnel,
books,  records  (including  Tax  records),   contracts,  and  documents  of  or
pertaining to the Company.

                  (b) The Seller  recognizes and acknowledges that he has had in
the past,  currently has, and in the future may possibly have, access to certain
confidential  information  of the  Company  and  the  Buyer,  such as  lists  of

valuable,  special and unique assets of the Company's and the Buyer's respective
businesses. The Seller agrees that it will not disclose Confidential Information
with  respect to the  Company  or the Buyer to any  person,  firm,  corporation,
association  or other  entity for any  purpose or reason  whatsoever,  except to
authorized  representatives  of the Buyer  and to  counsel  and other  advisers;

becomes  known to the  public  generally  through no fault of the  Seller,  (ii)
disclosure  is required  by law or the order of any  Governmental  Entity  under
color of law,  or (iii)  the  disclosing  party  reasonably  believes  that such
disclosure is required in connection  with the defense of a lawsuit  against the
disclosing party; and provided further, that prior to disclosing any information
pursuant to clause (i), (ii) or (iii) above, the Seller shall, if possible, give
prior  written  notice  thereof  to the Buyer  and  provide  the Buyer  with the
opportunity to contest such disclosure.

                  (c) The Buyer recognizes and  acknowledges  that it has had in
the past,  currently has, and in the future may possibly have, access to certain
confidential information of the Company, such as lists of customers, operational
policies,  and pricing and cost policies  that are valuable,  special and unique
assets of the Company's  business.  The Buyer agrees that, prior to the Closing,
it will not disclose confidential information with respect to the Company to any
person, firm, corporation, association or other entity for any purpose or reason
whatsoever,  except to authorized  representatives of the Company and the Seller
and to counsel and other  advisers and that they will not disclose  confidential

authorized  representatives  of the  Company  and the Seller and to counsel  and

information becomes known to the public generally through no fault of the Buyer,
(ii) disclosure is required by law or the order of any Governmental Entity under
color of law,  or (iii)  the  disclosing  party  reasonably  believes  that such

cure any misrepresentation, breach of warranty, or breach of covenant.

         5.7 Exclusivity.  The Seller will not (and the Seller will not cause or
permit the Company or any of the officers,  directors, agents,  representatives,
or  affiliates  of the Company  to) (a)  solicit,  initiate,  or  encourage  the

6. POST-CLOSING COVENANTS.

         The Parties  agree as follows with respect to the period  following the
Closing.

         6.1 General.  In case at any time after the Closing any further  action
is necessary or desirable to carry out the purposes of this  Agreement,  each of
the Parties will take such further action  (including the execution and delivery
of such further  instruments  and  documents) as any other Party  reasonably may
request,  all at the sole cost and expense of the  requesting  Party (unless the
requesting Party is entitled to indemnification therefor under Section 8 below).
The Seller  acknowledges  and agrees  that from and after the  Closing the Buyer
will be entitled to possession of all documents,  books,  records (including Tax
records), agreements, and financial data of any sort relating to the Company .

         6.2  Litigation  Support.  In the  event  and for so long as any  Party
actively is  contesting  or  defending  against any  action,  suit,  proceeding,
hearing,  investigation,  charge, complaint, claim, or demand in connection with
(i)  any  transaction  contemplated  under  this  Agreement  or (ii)  any  fact,
situation,   circumstance,   status,   condition,   activity,   practice,  plan,
occurrence,  event, incident, action, failure to act, or transaction on or prior
to the Closing  Date  involving  the  Company,  each of the other  Parties  will
cooperate with him or it and his or its counsel in the contest or defense,  make
available their personnel,  and provide such testimony and access to their books
and records as shall be necessary in connection with the contest or defense, all
at the sole cost and expense of the  contesting  or defending  Party (unless the
contesting  or defending  Party is entitled to  indemnification  therefor  under
Section 8 below).

         6.3      Transition.

         (a) The Seller will not take any action that is designed or intended to
have the effect of discouraging any lessor,  licensor,  customer,  supplier,  or
other  business  associate of the Company  from  maintaining  the same  business
relationships  with the  Company  after the  Closing as it  maintained  with the
Company prior to the Closing.  The Seller will use his best efforts to cooperate
with the Buyer to cause the Company to employ an individual  to serve  initially
as a vice president of the Company and expected to serve eventually as president
of the Company upon the termination of the Seller's employment with the Company.

         (b) The Parties  intend and expect that  subsequent  to the Closing and
until the expiration of the Second Earn Out Period,  the Company will operate as
a separate  subsidiary  of the Buyer and that the  Company  shall be operated in
accordance  with its historic  business  practices.  The Parties  understand and
acknowledge  that  Buyer  will  provide  certain  administrative  support to the
Company and that it is  anticipated  that the Company will benefit from mutually
beneficial  business synergies created by the transactions  contemplated by this
Agreement.  Except for certain  administrative  staff provided to the Company by
the Buyer,  the parties  acknowledge that the Buyer has no obligation to provide
additional  support or capital to the Company  from the Closing Date through the
end of the Second Earn Out Period. Within 30 days subsequent to the Closing, the
Seller shall submit a proposed  detailed  budget for each month of 1998 and 1999
to the Company's  Board of Directors for approval.  The parties  anticipate that
such budget will  demonstrate  sufficient  levels  revenues and  expenditures to
achieve the projected  net income  levels  included in Schedule 4.6 for 1998 and
1999.  During any Earn Out Period Buyer will not take any  actions,  without the
prior  approval  of the Board of  Directors  of AMI and the Buyer,  which  would
prevent the Buyer from performing its obligations under this Agreement.

         6.4      Covenant Not to Compete.

                  (a) Until  the  later of (x) the end of the four  year  period
following the Closing Date or (y) two years  subsequent to the date on which the
Seller's employment with the Company  Terminates,  the Seller shall not, for any
reason  whatsoever,  directly or  indirectly,  for himself or on behalf of or in
conjunction with any other person, persons, company,  partnership,  corporation,
business or other entity of whatever nature:

                           (i) engage, as a shareholder, owner,  partner,  joint
venturer,  or in a managerial  capacity,  whether as an independent  contractor,
consultant or advisor, or as a sales representative, in any business selling any
products  or  services in direct  competition  with the current  business of the
Company;

                           (ii) call upon any person  who is, at that  time,  an
employee  of the Buyer or the  Company  for the  purpose  or with the  intent of
enticing  such  employee  away  from or out of the  employ  of the  Buyer or the
Company; or

                           (iii)  call upon any  person  or entity  which is, at
that time, or which has been,  within one year prior to that time, a customer of
the  Company for the purpose of  soliciting  or selling  products or services in
competition with the Company.

                  Notwithstanding the above, the foregoing covenant shall not be
deemed to prohibit the Seller from acquiring as an investment not more than five
percent (5%) of the capital stock of a competing  business whose stock is traded
on a national securities exchange or over-the-counter.

                  (b) Damages.  Because of the difficulty of measuring  economic
losses  to the  Buyer as a result of a breach  of the  foregoing  covenant,  and
because of the  immediate  and  irreparable  damage  that could be caused to the
Buyer for which it would have no other adequate  remedy,  the Seller agrees that
the  foregoing  covenant  may be enforced by the Buyer in the event of breach by
the Seller, by injunctions and restraining orders.

                  (c) Reasonable Restraint. The parties agree that the foregoing
covenants  in this  Section 6.4 impose a  reasonable  restraint on the Seller in
light of the  activities  and business of the Buyer on the date of the execution
of this Agreement and the current plans of the Buyer;  but it is also the intent
of the Buyer and the Seller that such  covenants  be  construed  and enforced in
accordance with the changing activities and business of the Buyer throughout the
term of this  covenant.  The parties  further agree that in the event the Seller
shall enter into a business or pursue other  activities not in competition  with
the Buyer or similar activities or business in locations the operation of which,
under such circumstances,  does not violate Section 6.4(a), the Seller shall not
be chargeable with a violation of this Section 6.4 if the Buyer shall thereafter
enter the same, similar or a competitive (i) business, (ii) course of activities
or (iii) location, as applicable.

                  (d) Severability;  Reformation.  The covenants in this Section
6.4 are  severable  and  separate,  and  the  unenforceability  of any  specific
covenant shall not affect the provisions of any other covenant. Moreover, in the
event any court of competent  jurisdiction  shall determine that the scope, time
or territorial restrictions set forth are unreasonable, then it is the intention
of the parties that such  restrictions  be enforced to the fullest  extent which
the court deems reasonable, and the Agreement shall thereby be reformed.

                  (e) Independent Covenant. All of the covenants in this Section
6.4 shall be  construed as an agreement  independent  of any other  provision in
this Agreement,  and the existence of any claim or cause of action of the Seller
against the Buyer, whether predicated on this Agreement or otherwise,  shall not
constitute a defense to the  enforcement by the Buyer of such  covenants.  It is
specifically agreed that the period of noncompetition  stated at Section 6.4(a),
during which the agreements and covenants of the Seller made in this Section 6.4
shall be effective,  shall be computed by excluding  from such  computation  any
time during  which the Seller is found by a court of competent  jurisdiction  to
have been in  violation of any  provision  of this  Section  6.4. The  covenants
contained  in  Section  6.4 shall  not be  affected  by any  breach of any other
provision  hereof  by  any  party  hereto  and  shall  have  no  effect  if  the
transactions contemplated by this Agreement are not consummated.

                  (f)  Materiality.  The Seller hereby agrees that the covenants
set  forth  in this  Section  6.4 are a  material  and  substantial  part of the
transactions contemplated by this Agreement.

                  (g) Internet  Business.  Notwithstanding  the foregoing,  this
Section 6.4 shall not prohibit the Seller from entering into business activities
in which  Internet  dial-up access  services and Web hosting  services (the "Lin
Internet Business") are provided to customers ("Internet  Customers") so long as
none of any such Internet  Customers are customers or  prospective  customers of
ACS or the Company, as discussed by the Parties from time to time.

                  (e) the Buyer shall have delivered to the Seller a certificate
dated as of the Closing Date to the effect that each of the conditions specified
in Section 7.2(a) through (d) above is satisfied in all respects.

The Seller may waive any condition specified in this Section 7.2 if they execute
a writing so stating at or prior to the Closing.


8.       REMEDIES FOR BREACHES OF THIS AGREEMENT.

         8.1 Survival of Representations and Warranties.  Except with respect to
Sections 4.10 (Taxes), 4.23 (Employee Benefits), 4.25 (Government Contracts) and
4.26  (Environmental,   Health  and  Safety  Matters)  all  representations  and
warranties  contained  in  this  Agreement,  including  those  contained  in the
exhibits,  schedules and other documents  delivered  pursuant to this Agreement,
above shall survive the Closing  hereunder and continue in full force and effect
for a period of eighteen  months  thereafter.  All  covenants  contained in this
Agreement  likewise  shall survive the Closing,  but shall not be subject to the
limitation on survival set forth in the preceding sentence.  Representations and
warranties  contained in Section 4.25 and 4.26 shall  survive  Closing and shall
remain  in  full  force  and  effect  for  a  period  of   twenty-four   months.
Representations and warranties contained in Sections 4.10 and 4.23 shall survive
Closing and shall  remain in full force and effect for a period of three  years.
So long as a claim  arising out of a breach of a  representation  or warranty is
made prior to the expiration of such representation or warranty, indemnification
may be had (subject to the other  provisions of this Section 8)  notwithstanding
that the scope of loss may not be  determined,  remedial work completed or claim
otherwise resolved prior to such expiration.

         8.2  Indemnity.  Each party  hereto (the  "Indemnifying  Party")  shall
indemnify  and hold the  other  party  hereto  (each,  an  "Indemnified  Party")
harmless to the extent  provided in this  Section 8 from and against any and all
losses (consequential or otherwise), Liabilities, claims, disputes, proceedings,
demands,  cost unallowability  determinations,  judgments,  settlements,  liens,
costs and  expenses  of any nature  whatsoever  (including  reasonable  fees and
disbursements of attorneys, accountants, or other professional advisors relating
to investigation, prosecution, negotiation, defense, settlement, or appeal) (the
foregoing referred to individually as an "Adverse  Consequence" and collectively
as "Adverse Consequences") resulting from or arising out of

         (i) any breach of any  representation  or warranty of the  Indemnifying
Party  contained in this  Agreement or in any  schedule,  exhibit,  certificate,
document   or  other  item   delivered   by  the   Indemnifying   Party  or  its
representative(s) in connection with this Agreement;

         (ii) the  nonperformance,  partial  or total,  of any  covenant  of the
Indemnifying Party contained in this Agreement; and

         (iii) the scheduled items set forth on 4.10 or 4.19;

         (iv)  any  and  all  Adverse  Consequences  incidental  to  any  of the
foregoing  or to the  enforcement  of this  section  8.2.  Without  limiting the
foregoing,  the Seller's  indemnification  liabilities arising from Section 4 of
this  Agreement  shall include  Adverse  Consequences  consisting of any and all
Taxes of the Company with  respect to any period (or any portion  thereof) up to
and including  the Closing  Date,  except for Taxes of the Company (if any) that
are  reflected  as  current or  deferred  liabilities  for Taxes on the  Interim
Balance Sheet Date. The Seller hereby agrees that he will not make any claim for
indemnification  against  the  Company  by  reason  of the  fact  that  he was a
director,  officer,  employee,  or agent of the  Company  or was  serving at the
request of the Company as a partner, trustee,  director,  officer,  employee, or
agent  of  another  entity  (whether  such  claim  is  for  judgments,  damages,
penalties,  fines,  costs,  amounts paid in  settlement,  losses,  expenses,  or
otherwise and whether such claim is pursuant to any statute,  charter  document,
bylaw,  agreement,  or otherwise)  prior to the Closing Date with respect to any
action,  suit,  proceeding,  complaint,  claim,  or demand  brought by the Buyer
against the Seller (whether such action, suit, proceeding,  complaint, claim, or
demand is pursuant to this Agreement, applicable law, or otherwise).

         8.3      Notice of Claim.

         (a) If an  Indemnified  Party makes any claim  against an  Indemnifying
Party for  indemnification,  such claim  shall be in writing  and shall state in
general terms the facts upon which the Indemnified Party makes such claim.

         (b)  In  the  event  of  any  claim  or  demand  asserted  against  the
Indemnified  Party by a third party upon which the  Indemnified  Party may claim
indemnification,  the  Indemnifying  Party  shall  give  written  notice  to the
Indemnified  Party within 15 days after  receipt of notice from the  Indemnified
Party indicating whether the Indemnifying Party intends to assume the defense of
such claim or demand.  If the  Indemnifying  Party does assume such defense,  it
shall indemnify and hold the Indemnified Party harmless from and against any and
all losses,  damages and liabilities  caused by or arising out of any settlement
or  judgment  of such  claim  and  may  not  claim  that  it  does  not  have an
indemnification   obligation   with  respect   thereto.   Notwithstanding   such
assumption,  the  Indemnified  Party shall have the right to participate in such
defense,  by written notice given to the Indemnifying  Party within 15 days from
the date of the Indemnifying  Party's notice,  provided that such  participation
shall be at the expense of the  Indemnified  Party unless there is a conflict of
interest between the Indemnified Party and the Indemnifying Party, in which case
the cost of such participation  (including  attorneys' fees for counsel selected
by the Indemnified Party) shall be reimbursed by the Indemnifying  Party. If the
Indemnifying  Party assumes the defense and the Indemnified  Party elects not to
participate, the Indemnifying Party shall have the right fully to control and to
settle the proceeding.  If the  Indemnified  Party elects to participate in such
defense, the parties shall cooperate in the defense of the proceeding, and shall
not settle the same  without the  consent of each,  which  consent  shall not be
unreasonably withheld or delayed. If the Indemnifying Party elects not to assume
the defense, the Indemnified Party shall have the right to do so (at the expense
of the Indemnifying  Party),  and may settle the same without the consent of the
Indemnifying Party.

         (c)  In  the  event  an  Indemnified  Party  has  a  claim  against  an
Indemnifying  Party  hereunder  which does not  involve a claim  being  asserted
against or sought to be collected by a third party, the Indemnifying Party shall
give written  notice to the  Indemnified  Party within 15 days after  receipt of
notice from the Indemnified  Party  indicating  whether the  Indemnifying  Party
disputes such claim. If the  Indemnifying  Party does not notify the Indemnified
Party within such 15 day period that the Indemnifying Party disputes such claim,
the  amount  of such  claim  shall be  conclusively  deemed a  liability  of the
Indemnifying  Party hereunder.  In the event that the  Indemnifying  Party shall
object in writing to any claim made in accordance with this Section 8.3(c),  the
Indemnified  Party shall have 15 days to respond in a written  statement  to the
objection of the Indemnifying Party. If after such 15 day period there remains a
dispute as to any claims, the parties shall attempt in good faith for 30 days to
agree upon the rights of the  respective  parties  with  respect to each of such
claims.  If the  parties  should so  agree,  a  memorandum  setting  forth  such
agreement  shall be prepared and signed by both parties.  If the parties  cannot
agree  within such 30 day  period,  the parties  shall  jointly  select a single
arbitrator (the "Indemnification  Arbitrator"),  the selection of which will not
be unreasonably withheld by either party, who shall have substantial  experience
with  respect to the  substance  of the  matters  in dispute  and shall have the
authority  to hold  hearings  and to render a decision  in  accordance  with the
arbitration rules of the American Arbitration  Association.  The Indemnification
Arbitrator  shall settle any remaining  dispute by selecting the position of the
party that the Arbitrator  determines,  in its sole  discretion,  to be the most
correct. The determination of the Indemnification  Arbitrator shall be set forth
in  writing,  delivered  to each  of the  Buyer  and the  Seller  and  shall  be
conclusive  and binding on the parties  and shall be  non-appealable.  The party
whose  position is not chosen by the  Indemnification  Arbitrator  shall pay all
expenses of the Indemnification Arbitrator.

         8.4  Limitation.   Notwithstanding   the  above,  and  except  for  (i)
misrepresentations  and  breaches of  warranties  by the Seller  under  Sections
4.25(g)(iv) and (ii) Adverse  Consequences  resulting from or arising out of the
scheduled  items set forth on 4.10 or 4.19, the Seller shall not be liable under
this Section 8 (y) until the aggregate amount of Adverse Consequences in respect
of misrepresentations  and breaches of warranties to the Buyer exceeds $200,000,
and only to the extent of such  excess,  and (z) to the extent  that the Adverse
Consequences to the Buyer exceeds $10 million.

         8.5 Recoupment. The Buyer shall have the option of recouping all or any
part  of any  Adverse  Consequences  it may  suffer  (in  lieu  of  seeking  any
indemnification  to which it is entitled  under this Section 8) by notifying the
Seller  within 30 days from the end of the  applicable  Earn Out Period that the
Buyer is reducing the amount of any Contingent  Purchase Price otherwise payable
to the Seller. Any amount of the Contingent  Purchase Price not in dispute shall
be paid in  accordance  with Section 2.5. The written  notice shall  specify the
general,  factual  basis for such claim and the amount the  Contingent  Purchase
Price is to be reduced.  If the Seller has any objection to the  reduction,  the
Seller  shall  have 30 days to make  such  investigation  of the claim as Seller
deems  necessary or  desirable.  For the purposes of such  investigation,  Buyer
agrees  to make  available  to  Seller  or its  authorized  representatives  the
information relied upon by Buyer to substantiate the reduction. If the Buyer and
Seller do not agree within such 30 day period,  the matter shall be submitted to
arbitration in accordance with the arbitration rules of the American Arbitration
Association then in effect. Within such 30 day period, the parties shall jointly
select a single arbitrator (the "Recoupment Arbitrator"), the selection of which
will not be unreasonably  withheld by either party,  who shall have  substantial
experience  with  respect to the  substance  of the matters in dispute and shall
have the authority to hold hearings and to render a decision in accordance  with
the arbitration rules of the American  Arbitration  Association.  The Recoupment
Arbitrator  shall settle any remaining  dispute by selecting the position of the
party that the Arbitrator  determines,  in its sole  discretion,  to be the most
correct.  The  determination of the Recoupment  Arbitrator shall be set forth in
writing,  delivered to each of the Buyer and the Seller and shall be  conclusive
and binding on the parties and shall be non-appealable. The party whose position
is not  chosen  by the  Recoupment  Arbitrator  shall  pay all  expenses  of the
Recoupment  Arbitrator and interest accruing on the amount of reduction,  at the
rate of the regular commercial prime rate of interest of NationsBank N.A., which
NationsBank  N.A.  uses as a standard  for  determining  actual  interest  rates
charged  commercial  borrowers,  beginning on the date the  Contingent  Purchase
Price was otherwise due to be paid to the Seller.

9.       TAX MATTERS.

         The following  provisions shall govern the allocation of responsibility
as between  the Buyer and the Seller  for  certain  tax  matters  following  the
Closing Date:

         9.1 Section 338(h)(10)  Election.  The Seller agrees, if so directed by
the  Buyer,  to join with the Buyer in making an  election  under  Code  section
338(h)(10) (and any corresponding  elections under state,  local, or foreign tax
law)  (collectively,  a  "Section  338(h)(10)  Election")  with  respect  to the
purchase  and sale of the  Company  Shares.  The Seller  shall pay any "Tax" (as
defined in Section 4.10 above),  including  any liability of the Company for any
Tax resulting from application to it of applicable regulations,  attributable to
the making of the Section  338(h)(10)  Election and will indemnify the Buyer and
the Company against any Adverse  Consequences  arising out of any failure to pay
such Tax.  The  Seller  shall  also pay any  state,  local or  foreign  Tax (and
indemnify the Buyer and the Company against any Adverse consequences arising out
of any failure to pay such Tax)  attributable to an election under state,  local
or foreign law similar to the election available under Section 338(h)(10) of the
Code (or which results from the making of an election  under Section  338(h)(10)
of the Code) with respect to the purchase and sale of the Company hereunder.

         9.2 Tax Periods  Ending on or Before the Closing Date. The Seller shall
prepare or cause to be  prepared  and file or cause to be filed all Tax  Returns
for the Company for all periods  ending on or prior to the Closing Date that are
filed after the Closing  Date.  The Seller  shall permit the Buyer to review and
comment on each such Tax Return  described in the  preceding  sentence  prior to
filing. Seller shall pay any Taxes shown on any such Tax Returns.

         9.3 Allocation of Purchase Price. Within 15 days from the Closing Date,
the Buyer shall deliver to the Seller a draft  schedule  allocating the Purchase
Price and the liabilities of the Company among the assets of the Company for all
purposes  (including Tax and financial  accounting) in a manner  consistent with
the fair market values of such assets (the "Draft  Purchase Price  Allocation").
If the Seller has any  objection to the Draft  Purchase  Price  Allocation,  the
Seller shall deliver a detailed statement describing his objections to the Buyer
within 5 days after receiving the Draft Purchase Price Allocation. The Buyer and
the  Seller  will  use  reasonable   efforts  to  resolve  any  such  objections
themselves. If the Buyer and Seller do not finally resolve any of the objections
within 5 days after the Buyer has received the statement of objections, however,
the Buyer and the Seller will select,  within 5 days,  a  nationally  recognized
independent  accounting firm mutually acceptable to each party, the agreement to
the  selection  which shall not be  unreasonably  withheld,  to resolve any such
differences  (the  "Arbitrator").  The  Arbitrator  shall  settle any  remaining
dispute by selecting the position of the party that the  Arbitrator  determines,
in its  sole  discretion,  to be the  most  correct.  The  determination  of the
Arbitrator shall be set forth in writing, delivered to each of the Buyer and the
Seller  and  shall  be  conclusive  and  binding  on the  parties  and  shall be
non-appealable.  The party whose position is not chosen by the Arbitrator  shall
pay all expenses of the  Arbitrator.  The Draft  Purchase Price  Allocation,  as
adjusted  for any items of dispute  resolved by the Buyer and the Seller and for
any  determinations  of the Arbitrator shall be referred to herein as the "Final
Purchase  Price  Allocation."  The Buyer and the Seller will file and the Seller
will cause the Company to file all Tax Returns  (including  amended  returns and
claims for refund) and information reports in a manner consistent with the Final
Purchase Price Allocation.

         9.4 S Corporation  Status.  The Seller will not, and will not allow the
Company to, revoke the Company's election to be taxed as an S corporation within
the meaning of Code  sections  1361 and 1362.  The Seller will not, and will not
allow  the  Company  to,  take or allow  any  action  that  would  result in the
termination of the Company's status as a validly  existing S corporation  within
the meaning of Code sections 1361 and 1362.

         9.5 Tax Periods Beginning Before and Ending After the Closing Date. The
Buyer shall  prepare,  or cause to be prepared,  and file, or cause to be filed,
any Tax Returns of the Company  for Tax periods  which begin  before the Closing
Date and end after the Closing Date. The Buyer shall permit the Seller to review
and comment upon each such Tax Return described in the preceding  sentence prior
to filing.  The Seller shall pay to the Buyer within fifteen (15) days after the
date on which Taxes are paid with respect to such periods an amount equal to the
portion of such Taxes which relates to the portion of such Taxable period ending
on the Closing  Date to the extent such Taxes are not  reflected  in the reserve
for Tax Liability  (rather than any reserve for deferred  Taxes  established  to
reflect timing differences between book and Tax income) shown on the face of the
Closing Date Balance  Sheet.  For purposes of this  Section,  in the case of any
Taxes that are imposed on a periodic  basis and are payable for a Taxable period
that includes  (but does not end on) the Closing  Date,  the portion of such Tax
which  relates to the portion of such Taxable  period ending on the Closing Date
shall (x) in the case of any Taxes  other  than  Taxes  based upon or related to
income  or  receipts,  be deemed  to be the  amount  of such Tax for the  entire
Taxable period  multiplied by a fraction the numerator of which is the number of
days in the Taxable  period  ending on the Closing Date and the  denominator  of
which is the number of days in the entire  Taxable period and (y) in the case of
any Tax based  upon or  related  to income or  receipts  be deemed  equal to the
amount  which  would be  payable if the  relevant  Taxable  period  ended on the
Closing Date.  Any credits  relating to a Taxable  period that begins before and
ends after the Closing  Date shall be taken into  account as though the relevant
Taxable period ended on the Closing Date. All  determinations  necessary to give
effect to the foregoing  allocations  shall be made in a manner  consistent with
prior practice of the Company .

         9.6      Cooperation on Tax Matters.

                  (a) The Buyer and the Seller shall, and the Seller shall cause
the Company to,  cooperate fully, as and to the extent  reasonably  requested by
the other party, in connection  with the filing of Tax Returns  pursuant to this
Section and any audit,  litigation  or other  proceeding  with respect to Taxes.
Such  cooperation  shall  include  the  retention  and (upon  the other  party's
request) the provision of records and information which are reasonably  relevant
to any such audit, litigation or other proceeding and making employees available
on a mutually convenient basis to provide additional information and explanation
of any material  provided  hereunder.  The Seller agrees (i) to retain all books
and records with respect to Tax matters pertinent to the Company relating to any
taxable period beginning before the Closing Date (except those books and records
in the  custody  of  the  Company)  until  the  expiration  of  the  statute  of
limitations  (and, to the extent notified by Buyer,  any extensions  thereof) of
the respective taxable periods,  and to abide by all record retention agreements
entered into with any taxing  authority,  and (ii) to give the Buyer  reasonable
written  notice prior to  transferring,  destroying or discarding any such books
and records and, if the Buyer requests, the Seller shall allow the Buyer to take
possession of such books and records.

                  (b) Buyer and Seller further agree, upon request, to use their
best efforts to obtain any  certificate or other document from any  Governmental
Entity or any other Person as may be necessary to mitigate,  reduce or eliminate
any Tax that could be imposed  (including,  but not limited to, with  respect to
the transactions contemplated hereby).

                  (c) Buyer and Seller further agree,  upon request,  to provide
the other party with all information that either party may be required to report
pursuant to Section  6043 of the Code and all  Treasury  Department  Regulations
promulgated thereunder.


10.      TERMINATION AND MISCELLANEOUS.

         10.1     Termination  of  Agreement. This  Agreement may be terminated
at any time prior to the Closing  Date solely:
                  
                  (a) by mutual consent of the Buyer and the Seller; or

                  (b) by the  Seller  or by the Buyer if the  Closing  shall not
have occurred on or before March 15, 1998; provided,  however, that the right to
terminate  this Agreement  under this Section  10.1(b) shall not be available to
either party whose material misrepresentation,  breach of warranty or failure to
fulfill any  obligation  under this Agreement has been the cause of, or resulted
in, the failure of the Closing to occur on or before such date; or

                  (c) by the  Seller  or by the  Buyer if there is or has been a
material breach, failure to fulfill or default on the part of the other party of
any of the  representations  and warranties  contained  herein or in the due and
timely  performance  and  satisfaction  of any of the  covenants,  agreements or
conditions  contained herein, and the curing of such default shall not have been
made or shall not reasonably be expected to occur before the Closing Date; or

                  (d) by the  Seller or by the  Buyer if there  shall be a final
nonappealable   order  of  a  federal  or  state  court  in  effect   preventing
consummation  of the  Purchase;  or there  shall  be any  action  taken,  or any
statute,  rule,  regulation or order  enacted,  promulgated  or issued or deemed
applicable  to the  Purchase  by any  Governmental  Entity  which would make the
consummation of the Purchase illegal.

         10.2 Effect of  Termination.  In the event of the  termination  of this
Agreement  pursuant to Section 10.1, this Agreement shall forthwith become void,
and there shall be no liability or obligation on the part of any party hereto or
its officers, directors,  stockholders or members. Notwithstanding the foregoing
sentence,  (i) the provisions of this Section 10.2,  Sections  5.5(b) and 5.5(c)
(confidentiality)  and the other  provisions  of Section 10  (including  without
limitation  brokers  and  expenses),  shall  remain in full force and effect and
survive any termination of this  Agreement;  (ii) each party shall remain liable
for any  breach of this  Agreement  prior to its  termination;  and (iii) in the
event of termination of this Agreement  pursuant to Section 10.1(c) above,  then
notwithstanding  the provisions of Section 10.7 below, the breaching party shall
be liable to the other  party to the  extent of the  expenses  incurred  by such
other party in connection with this Agreement and the transactions  contemplated
hereby, as well as any damages in accordance with applicable law.

         10.3   Cooperation.   The  Seller   and  the  Buyer,   for  no  further
consideration,  shall each  deliver or cause to be delivered to the other on the
Closing  Date,  and either  before or after the Closing Date at such other times
and places as shall be reasonably agreed to, such additional  instruments as the
other may reasonably request for the purpose of carrying out this Agreement.  In
connection therewith,  if required,  the President or Chief Financial Officer of
the Company will execute any  documentation  reasonably  required by the Buyer's
independent  public  accountants (in connection with such accountant's  audit of
the Company) or the Nasdaq National Market. Without limitation of the foregoing,
the Seller will cooperate and use its reasonable  efforts to cause the Company's
present  officers,  directors and employees  cooperate with the Buyer before, on
and after the Closing Date in furnishing  information,  evidence,  testimony and
other assistance in connection with any, actions,  proceedings,  arrangements or
disputes of any nature with respect to matters  pertaining  to all periods prior
to the Closing Date and the Buyer will cooperate and use its reasonable  efforts
to cause its present officers, directors and employees cooperate with the Seller
before,  on and after the Closing Date in  furnishing  any such  information  to
employees  of the Seller  and/or the Company who will be  continuing  employment
with the Company after the sale,  regarding such continued  employment.  Without
limitation of the foregoing,  in connection with any securities  filing required
of the Buyer as a result of the Purchase,  (i) the Seller will cooperate and use
its reasonable efforts to assist the Buyer and the Company in the preparation of
audited and  unaudited (as required)  financial  statements  for the Company and
(ii) the Seller will use its reasonable  efforts to cause its accountants at the
Buyer's  sole cost and  expense,  to assist  the  Buyer and the  Company  in the
preparation of such financial statements.

         10.4  Successors  and  Assigns.  This  Agreement  and the rights of the
parties  hereunder may not be assigned (except by operation of law) and shall be
binding  upon  and  shall  inure  to the  benefit  of the  parties  hereto,  the
successors of the Buyer, and the heirs and legal representatives of the Seller.

hereto. Any and all previous agreements and understandings  between or among the
parties  regarding  the subject  matter  hereof,  whether  written or oral,  are
superseded by this Agreement.

         10.6  Counterparts.  This  Agreement  may be  executed in any number of
counterparts  and any party  hereto may  execute any such  counterpart,  each of
which when executed and  delivered  shall be deemed to be an original and all of
which  counterparts  taken  together  shall  constitute  but one  and  the  same
instrument.  This Agreement  shall become binding when one or more  counterparts
taken together shall have been executed and delivered  (which  deliveries may be
by telefax) by the parties.

         10.7 Expenses.  The Buyer has paid and will pay the fees,  expenses and

         10.8 Notices.  Any notice,  request,  claim, demand,  waiver,  consent,
