Item 2.  Acquisition or Disposition of Assets.

         On July 1, 1998, the registrant  acquired all of the outstanding shares
of capital stock of Kavouras, Inc., a Minnesota corporation, pursuant to a Stock
Purchase  Agreement dated March 30, 1998 among the registrant and the holders of
all of the common stock of  Kavouras,  Inc.  and an  Agreement  Regarding  Stock
Acquisition  dated March 30, 1998 among  Stephen P.  Kavouras  and two trusts of
which he is a  beneficiary  and  which  were  the  controlling  shareholders  of
Kavouras, Inc. (collectively the "Controlling Shareholders") and the registrant.
Copies of such agreements are filed as Exhibits to this Form 8-K Current Report.

         Kavouras,  Inc.  is engaged in the  development,  design,  manufacture,
marketing  and  service  of  meteorological  equipment  and in the  business  of
providing  meteorological  data services to government,  aviation and commercial
broadcast users.  The registrant  intends to continue to use the physical assets
of Kavouras,  Inc.  (which  includes a network of  transmitters  throughout  the
United  States of America  through  which it provides its  customers  with color
video  displays  and  hard  copies  of  weather  radar,  weather  satellite  and
alphanumeric weather information) for the same business purposes. Kavouras, Inc.
has  been  and  will  be  a  major  supplier  of  meteorological  data  for  the
registrant's weather information services.

         The  aggregate  consideration  given for the common  stock of Kavouras,
Inc.  consisted of  $16,400,000  in cash, of which  $13,717,961  was paid to the
Controlling  Shareholders.  The  amount  of the  acquisition  consideration  was
determined  by  the  registrant   based  upon  its  analysis  of  the  financial
projections of Kavouras, Inc., the strategic position in the weather information
business to be gained with the  combination  of weather  products  and  services
provided by Kavouras,  Inc. and the registrant,  and negotiations with Kavouras,
Inc.  which had other  bidders.  The  acquisition  of Kavouras,  Inc.  gives the
registrant  control of a major source of its timely weather  information,  entry
into high-end weather markets (television  broadcasting),  vertical  integration
from the weather source (radar) to the final weather data display, and access to
international weather markets.

         As  part  of  the   acquisition,   the   registrant   entered   into  a
Confidentiality and Non-Competition  Agreement with Stephen P. Kavouras pursuant
to which he agrees not to compete  with the  registrant  in certain  business in
exchange for consideration of $4,000,000.  In addition,  the registrant  entered
into a five year employment agreement with Stephen P. Kavouras, which includes a
$450,000  signing  bonus.  The  registrant  also  agreed  with  the  Controlling
Shareholders to have Kavouras,  Inc. distribute  retention bonuses to certain of
its key employees.

         The  funds  used  to  finance  the  acquisition  were  borrowed  by the
registrant  under its  revolving  credit  facility  with First  National Bank of
Omaha,  First National  Bank,  Wahoo,  Nebraska,  NBD Bank,  N.A.,  Norwest Bank
Nebraska, N.A., Bank of Montreal,  LaSalle National Bank, Mercantile Bank of St.
Louis, N.A., U.S. Bank, National Association, and Nationsbank, N.A.

         Details of such  acquisition  also are  contained in the news  releases
issued by the registrant on March 31, 1998 and July 6, 1998, copies of which are
filed as Exhibits to this Form 8-K Current Report.

Report of Independent Accountants

To the Directors and Stockholders of
Kavouras, Inc.:

We have audited the accompanying  consolidated balance sheets of Kavouras,  Inc.
and subsidiaries as of December 31, 1997 and 1996, and the related  consolidated
statements of operations and retained earnings and cash flows for the years then
ended.  These  financial  statements  are the  responsibility  of the  Company's
management.  Our  responsibility  is to express  an  opinion on these  financial
statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects, the consolidated financial position of Kavouras, Inc. and
subsidiaries as of December 31, 1997 and 1997, and the  consolidated  results of
their  operations  and their cash  flows for the years then ended in  conformity
with generally accepted accounting principles.

As discussed in Note 2 to the consolidated  financial  statements,  on March 30,
1998, the Company entered into a stock purchase agreement to sell the Company.

Kavouras, Inc.
Notes to Consolidated Financial Statements


1.     Summary of Significant Accounting Policies:
       
       Nature of Business:

       Kavouras,  Inc.  (the  Company)  is engaged in the  development,  design,
       manufacture,  marketing and service of meteorological  equipment and also
       provides  meteorological  data  services  to  government,   aviation  and
       commercial   broadcast   users.   The  Company   operates  a  network  of
       transmitters  throughout  the United States through which it provides its
       customers  with color video  displays  and hard copies of weather  radar,
       weather satellite and alphanumeric weather information.

       Principles of Consolidation:

       The consolidated financial statements include the accounts of the Company
       and its wholly owned subsidiaries.  All significant intercompany accounts
       and transactions have been eliminated in consolidation.

       Interim Statements

       The information furnished herein relating to interim periods has not been
       audited  by  independent   Certified  Public  Accountants.   The  interim
       financial  information in this report reflects all adjustments which are,
       in the opinion of  management,  necessary for a fair statement of results
       for the interim periods  presented in accordance with generally  accepted
       accounting  principles.  All such  adjustments are of a normal  recurring
       nature.  The results of operations for the six months ended June 30, 1998
       are not necessarily indicative of the results to be expected for the full
       year.

       Concentrations of Credit Risk:

       Financial   instruments   which   potentially   subject  the  Company  to
       concentrations  of credit risk  consist  primarily  of cash and  accounts
       receivable.  Substantially all of the Company's cash at December 31, 1997
       and 1996, was held by one financial institution. Substantially all of the
       Company's  accounts  receivable are due from customers located throughout
       the United States, and several foreign countries.

       Inventories:

       Inventories  are  stated  at the  lower  of  cost  or  market  with  cost
       determined on a first-in, first-out basis.

       Property and Equipment:

       Property and equipment are stated at cost.  Expenditures for improvements
       which  extend  useful  lives  are  capitalized  while   expenditures  for
       maintenance and repairs are charged to expense as incurred.  Depreciation
       and  amortization  are  calculated on the  straight-line  method over the
       estimated  useful asset lives of three to forty years.  When  property or
       equipment is retired from service or otherwise  disposed of, the cost and
       related  accumulated  depreciation or  amortization  are removed from the
       asset accounts with the resulting gain or loss included in operations.

       Income Taxes:

       Deferred  income taxes are recognized for the tax  consequences in future
       years of differences  between the tax basis of assets and liabilities and
       their financial  reporting  amounts at each year end based on enacted tax
       laws and  statutory  tax rates  applicable  to the  periods  in which the
       differences are expected to affect taxable income.  Valuation  allowances
       are  established  when  necessary  to reduce  deferred  tax assets to the
       amount expected to be realized. Income tax expense is the tax payable for
       the period and the change  during the period in  deferred  tax assets and
       liabilities.


                                      -11-

       Revenue Recognition:

       Sales are recognized  when the goods are shipped or services are rendered
       to the  customer  except  sales under  long-term  contracts.  Sales under
       long-term  contracts  are  recorded  under  the  percentage-of-completion
       method,  wherein revenue is recognized based on costs and estimated gross
       margin during the period the work is performed.  Revenue is recognized as
       a percentage of estimated  total revenue based on the  relationship  that
       incurred  costs to date bear to the most recent  estimate of total costs.
       The  cumulative  impact of revisions in total cost  estimates  during the
       progress of work is reflected in the year in which these  changes  become
       known.

       Research and Development:

       Expenditures  for research and development are charged to expense as they
       are incurred.

       Use of Estimates:

       The  preparation  of financial  statements in conformity  with  generally
       accepted accounting  principles requires management to make estimates and
       assumptions  that affect the reported  amounts of assets and  liabilities
       and  disclosure of contingent  assets and  liabilities at the date of the
       financial  statements  and the reported  amounts of revenues and expenses
       during the  reporting  period.  Actual  results  could  differ from those
       estimates.   The  most  significant   areas  which  require  the  use  of
       management's   estimates   relates  to  the   collectibility  of  certain
       receivables,  the  determination  of  net  realizable  value  of  certain
       inventory  items,  the  determination  of its warranty  accrual,  and the
       realizability of deferred tax benefits.

       New Accounting Standards:

       In June 1997,  the  Financial  Accounting  Standards  Board (FASB) issued
       Statement of Financial  Accounting  Standards (SFAS) No. 130,  "Reporting
       Comprehensive  Income,"  which  establishes  standards  for reporting and
       display of comprehensive  income and its components  (revenue,  expenses,
       gains and losses) in a full set of general-purpose  financial statements.
       Management  does not  expect  any  differences  between  net  income  and
       comprehensive income.

       The  FASB  issued  SFAS  No.  131,  "Disclosures  About  Segments  of  an
       Enterprise and Related  Information." SFAS N0. 131 establishes  standards
       for reporting  operating  segment  information in both annual reports and
       interim  financial  reports  issued  to  shareholders.   The  Company  is
       reviewing the  requirements of SFAS No. 131, and has not determined if it
       will be required to present  segment  information  beyond the one segment
       currently  presented.  SFAS No. 131 is required  to be adopted  effective
       with the Company's year-end 1998 reporting.

       In March  1997,  the  Accounting  Standards  Executive  Committee  issued
       Statement of Position (SOP) 98-1 as amended by SOP 98-4,  "Accounting for
       the Costs of Computer  Software  Developed or Obtained for Internal Use."
       This SOP  provides  guidance  on  accounting  for the  costs of  computer
       software  development  or  obtained  for  internal  use.  The  Company is
       reviewing  the  requirements  of the SOP and has not  determined if it is
       applicable  to the  Company.  SOP 98-1 is  required  to be adopted by the
       Company no later than the year ending December 31, 1999.

2.     Pending Sale of the Company:

       On March 30, 1998, the Company and Data Transmission  Network Corporation
       (DTN)  executed a Stock Purchase  Agreement  whereby DTN will acquire all
       outstanding shares of the Company at a predetermined price per share. The
       agreement is subject to  regulatory  approval and is expected to close on
       July 1, 1998.

</TABLE>

       The valuation  allowance for net deferred tax assets decreased in 1997 by
       $100,000.  The reduction was the result of higher  profitability  and the
       utilization of research and development tax credit carryforwards.

       For income tax  reporting  purposes,  the  Company  has federal and state
       research  and  development  tax  credit  carryforwards  of  $378,000  and
       $236,000,  respectively,  which expire at various dates from 2004 through
       2011. In addition,  the Company has available federal alternative minimum
       tax credit  carryforwards  of  approximately  $17,000 with no  expiration
       date.  The  utilization  of these  carryforwards  is  dependent  upon the
       Company's  ability  to  generate  sufficient  taxable  income  during the
       carryforward  periods and is subject to annual  usage  limitations  under
       provisions of the Internal Revenue Code.

8.     Employee Benefit Plans:

       The Company maintains a contributory  defined  contribution savings plan,
       which  qualifies  under Section  401(k) of the Internal  Revenue Code and
       covers employees who meet certain age and service requirements.  Employee
       contributions  are limited to the maximum  amount allowed by the Internal
       Revenue Code. The Company may make discretionary contributions, which are
       allocable to  participants  based on employee  contributions.  During the
       1997 and 1996,  approximately  $90,554  and  $89,189,  respectively,  was
       charged to operations for  contributions  to the plan and  administrative
       fees.

       In 1997, the Company  established a defined  contribution  profit sharing
       plan,  which covers  employees  who have  completed  one year of service.
       Contributions  to the  plan  are  determined  annually  by  the  Company.
       Contributions  to the plan totaled  $194,800 for the year ended  December
       31, 1997.

9.     Significant Customers:

       A portion of the Company's  sales have been derived from one  significant
       customer,  an  agency  of  the  United  States  Government,  representing
       approximately 10% and 13% of total sales in 1997 and 1996,  respectively,
       and 13% and 16% of accounts  receivable  at  December  31, 1997 and 1996,
       respectively.  In addition,  foreign sales  represent 8% and 11% of total
       sales in 1997 and 1996, respectively.

10.    Subsequent Event:

       On January 30, 1998, the Company entered into a consulting agreement with
       Earth  Watch  Communications,  Inc.,  a provider  of  integrated  weather
       systems.  This  agreement  requires the Company to make cash  payments in
       consideration for consulting services through May 1997 totaling $240,000.

       On April 6, 1998,  the Company  entered  into an  exclusive  royalty free
       license agreement with Earth Watch Communications, Inc., through the year
       2018 which provides the Company with certain  software rights  throughout
       the world with the exception of the United States and Canada, in exchange
       for a cash  payment of  $1,500,000.  Upon  execution  of this  agreement,
       payment was remitted by DTN (see Note 2) and all rights of the  agreement
       were  assigned by the Company to DTN.  In  addition,  the Company has the
       option to acquire  royalty free license  rights for the United States and
       Canada for  $1,500,000.  This option must be  exercised on or before June
       20, 1998.

                PRO FORMA UNAUDITED COMBINED FINANCIAL STATEMENTS

         The pro forma unaudited  combined  financial  statements of the Company
have been prepared to give effect to (1) the  Acquisition of all the outstanding
shares of capital stock of Kavouras,  Inc., and (2) the  Acquisition  financing.
The acquisition purchase price of $22,650,000 is made up of: (1) $16,400,000 for
100% of the capital stock outstanding,  (2) $4,000,000 for a Confidentiality and
Non-Competition  Agreement with Stephen P.  Kavouras,  (3) $450,000 in a signing
bonus to  Stephen  P.  Kavouras  for a five year  employment  agreement  and (4)
$1,800,000 for  non-contingent  retention  bonuses to certain key employees.  At
closing,  $20,650,000  was paid with the  remaining  $2,000,000  relating to the
Confidentiality  and  Non-Competition  Agreement  to be paid in  equal  $500,000
payments over the next four anniversary  dates of closing.  The Company used its
existing  operating line of credit to fund this  acquisition.  In addition,  the
proforma  unaudited combined  financial  statements reflect purchase  accounting
adjustments  to  the  carrying  value  of  certain  Kavouras,  Inc.  assets  and
liabilities to fair value.

         These pro forma combined  financial  statements have been derived from,
and should be read in conjunction with, the historical  financial statements and
related  notes of the  Company  and  Kavouras  contained  herein.  The Pro Forma
Combined  Balance Sheet assumes that the Acquisition  and the  Acquisition  Loan
occurred as of June, 30, 1998.  The Pro Forma Combined  Statements of Operations
assume that all such transactions occurred on January 1, 1997.

         The pro forma adjustments are based on available financial  information
and  certain  estimates  and  assumptions.  Therefore,  it is likely that actual
results will differ from the pro forma  adjustments.  Management  of the Company
believes  that any  differences  between  the actual  results  and the pro forma
adjustments will not have a material effect on the pro forma combined  financial
statements as presented herein.

         THE  FOLLOWING  UNAUDITED  PRO FORMA  FINANCIAL  DATA ARE PRESENTED FOR
INFORMATIONAL  PURPOSES ONLY AND ARE NOT  NECESSARILY  INDICATIVE OF THE RESULTS
THAT ACTUALLY WOULD HAVE OCCURRED HAD THE ACQUISITION  AND THE ACQUISITION  LOAN
BEEN  CONSUMMATED  ON THE DATES  INDICATED  OR THE RESULTS  THAT MAY OCCUR OR BE
OBTAINED IN THE FUTURE.

            Subscription  revenue  reduction of  $1,433,000  related to business

            acquisition.

(b)      Increase in  depreciation  and  amortization  due to intangible  assets
         (goodwill)  capitalized as a result of the acquisition.  The intangible
         assets   consist  of   $13,238,749   of  goodwill,   $4,000,000   of  a
         non-competition agreement and $450,000 of an employment agreement which

                     For the six Months Ended June 30, 1998


(a)      Reflects  elimination of business activities  occurring between the two
         companies prior to the acquisition. These items include:

                 Subscription  revenue reduction of $907,000 related to business
                 revenue  incurred  between  the  two  companies  prior  to  the
                 acquisition.

                 Quotes,  news  and  information  costs  reduction  of  $907,000
                 related to business expenses incurred between the two companies
                 prior to the acquisition.

(b)      Increase in  depreciation  and  amortization  due to intangible  assets
         (goodwill)  capitalized as a result of the acquisition.  The intangible
         assets   consist  of   $13,238,749   of  goodwill,   $4,000,000   of  a
         non-competition agreement and $450,000 of an employment agreement which
         are being  amortized using the  straight-line  method over ten and five
         years respectively.

(c)      Increase in  interest  expense due to the  addition of  $20,650,000  in
         long-term  debt as a result of the  acquisition.  This debt is from the
         Company's revolving line of credit and is accuring interest at the rate
         of 7.50%.

(d)      Increase in income tax benefit due to net loss  created  from pro forma
         adjustments  stated above,  calculated at the current provision rate of
         36%.

(e)      Adjustments  to reflect  reclassifications  of revenue and  expenses to

license,  franchise,  permit,  lease,  contract,  agreement or other instrument,

assets,  liabilities,  business or financial  condition of the Company; or (iii)
assuming   compliance  with  all  antitrust  laws,   violate  any  order,  writ,

assets, liabilities,  business or financial condition of the Company, taken as a
whole.

stock of the Company,  including securities convertible into or exchangeable for
such securities, by the issuer (any such transaction being referred to herein as

                                   ARTICLE VI
                          SURVIVAL AND INDEMNIFICATION

         6.01  Survival  of  Representations,   Warranties  and  Covenants.  All
covenants and  agreements of any party hereto set forth herein shall survive the
Closing for the period provided for in such covenant or, if not so provided, for

survive the Closing and shall remain in effect for a period of one year from the
Closing Date.

         6.02 Post-Closing Indemnification. (a) From and after the Closing Date,
Buyer  shall  defend,  indemnify  and hold  harmless  Sellers  and their  heirs,
trustees,  successors and assigns  against and in respect of any and all losses,
actions, suits,  proceedings,  claims,  liabilities,  damages, causes of action,
demands,  assessments,  judgments,  and investigations and any and all costs and
expenses  paid  to  third  parties,  including  without  limitation,  reasonable
attorneys' fees and expenses, suffered by any of them as a result of, or arising
from, any inaccuracy in or breach of or omission from any of the representations
or warranties made by Buyer in Article III of this Agreement or pursuant hereto,
or any non-fulfillment,  partial or total, of any of the covenants or agreements
made by Buyer in this Agreement to the extent not waived by Sellers in writing.

         (b)  From and  after  the  Closing  Date,  each  Seller  shall  defend,
indemnify  and hold  harmless  the Buyer  and its  subsidiaries  (including  the
Company)  and  each  of  their  successors,  assigns,  officers,  directors  and
employees (the "Buyer  Indemnitee  Group") against and in respect of any and all
losses, actions, suits,  proceedings,  claims,  liabilities,  damages, causes of
action,  demands,  assessments,  judgments,  and  investigations and any and all
costs  and  expenses  paid  to  third  parties,  including  without  limitation,
reasonable  attorneys' fees and expenses suffered by any of them as a result of,
or arising  from,  any  inaccuracy  in or breach of or omission  from any of the
representations  or  warranties  made  by  such  Seller  in  Article  II of this
Agreement or pursuant hereto, or any  non-fulfillment,  partial or total, of any
of the covenants or agreements made by such Seller in this Agreement.

         (c) If a claim by a third party is made against an  indemnified  party,
and if such party  intends to seek  indemnity  with respect  thereto  under this
Article VI, the  indemnified  party shall  promptly  (and in any case within ten
days of such claim  being  made)  notify the  indemnifying  party of such claim,
provided,  however,  that the failure to so notify the indemnifying  party shall
not discharge the  indemnifying  party of its obligations  hereunder except that
the indemnifying  party shall not be liable for default judgments or any amounts


                                      -35-
<PAGE>

related  thereto  if the  indemnified  party  shall  not  have so  notified  the
indemnifying party.  Subject to the following  sentence,  the indemnifying party
shall have thirty days after  receipt of such notice to  undertake,  conduct and
control,  through  counsel of its own  choosing  (which is  satisfactory  to the
indemnified party) the settlement or defense thereof,  and the indemnified party
shall cooperate with it in connection  therewith (provided that the indemnifying
party shall permit the  indemnified  party to participate in such  settlement or
defense through counsel chosen by the indemnified party,  provided that the fees
and expenses of such counsel  shall be borne by the  indemnified  party) and the
indemnifying  party shall promptly  reimburse the indemnified party for the full
amount  of any loss  resulting  from  such  claim and all  related  expenses  as
incurred  by  the   indemnified   party  within   limits  of  this  Article  VI.
Notwithstanding  anything herein to the contrary,  the  indemnified  party shall
have the right to conduct and control the defense of any such claim in the event
that such claim (including a claim for equitable  relief) or the continuation of
such claim  could  reasonably  be expected to  materially  adversely  affect the
business,  results  of  operations,  prospects  or  financial  condition  of the
indemnified party or any of its affiliates,  provided, however, that (i) in such
event the  indemnified  party's  selection  of  counsel  shall be subject to the
approval of the  indemnifying  party,  which approval shall not be  unreasonably
withheld,  and (ii) the indemnified party may not settle any claim for an amount
in excess of  $25,000  or  consent to any  settlement  which  imposes  equitable
remedies on the indemnifying  party or its affiliates  without the prior consent
of the  indemnifying  party,  which consent shall not be unreasonably  withheld,
unless the indemnified party agrees to waive any right to indemnity  therefor by
the  indemnifying   party.  If  the  indemnifying  party  does  not  notify  the
indemnified  party  within  thirty  days after the  receipt  of the  indemnified
party's notice of a claim of indemnity hereunder that it elects to undertake the
defense thereof or if the  indemnifying  party is not reasonably  contesting the
claim in good  faith,  the  indemnified  party  shall have the right to contest,
settle or compromise the claim in the exercise of its reasonable  judgment,  and
all losses incurred by the indemnified party, including all fees and expenses of
counsel for the indemnified party, shall be paid by the indemnifying party.

         (d) Claims for  indemnification  made under this  Section 6.02 shall be
made within a period of one year from the Closing Date.

         6.03 Limitation on Indemnification.  (a) Notwithstanding the provisions
of Section  6.02(a)  hereof,  Buyer shall not be obligated to indemnify and hold
harmless Sellers until the aggregate of all claims for which  indemnification is
sought against Buyer under Section 6.02(a) of this Agreement and Section 6.02(b)
of the Agreement Regarding Stock Acquisition  exceeds, in the aggregate,  Eighty
Thousand  Dollars  ($80,000),  and then only as to the amount by which aggregate
claims  thereunder exceed $80,000.  Buyer's aggregate  liability with respect to
the  indemnification  contained in Section 6.02(a) of this Agreement and Section
6.02(b)  of  the  Agreement   Regarding  Stock   Acquisition  shall  not  exceed
$2,000,000,  and each party hereto  waives (on its own behalf,  and on behalf of
all   indemnified   persons  named   hereunder   benefiting  from  such  party's
indemnification) any and all rights, claims and causes of action that it or such
persons may have  against  the  indemnifying  party  under such  indemnification
provisions to the extent such rights, claims and causes of action would or could
result in aggregate liability of the indemnifying party in excess of $2,000,000.

         (b)  Notwithstanding  the  provisions of Section  6.02(b)  hereof,  the
aggregate  liability  under this  Agreement  of each Seller shall not exceed the
amount set forth  opposite  such  Seller's  name in Schedule 1 attached  hereto,
being the purchase price for such Seller's Shares.

         (c) Except for liability provided for in Section 7.02(b) hereof and the
remedy of specific  performance  provided for in Section 8.12 hereof, each party
hereto  acknowledges  and agrees that his, her or its sole and exclusive  remedy
with  respect  to any and all  claims  relating  to the  subject  matter of this
Agreement shall be pursuant to the indemnification  provisions set forth in this
Article VI. In furtherance of the foregoing,  each party waives,  to the fullest
extent permitted under applicable law, any and all rights,  claims and causes of

                                      -36-
<PAGE>

action that it may have against the other party  arising under or based upon any
federal, state or local statute, law, ordinance,  rule or regulation, or arising

         7.01 Termination. This Agreement may be terminated at any time prior to
the Closing:
         
         (a) by the mutual consent of Buyer and a majority of Sellers; or

         (b) by either  Buyer or a majority of Sellers if the Closing  shall not
have occurred on or before December 31, 1998 or such later date as may be agreed
upon by Buyer, and a majority of Sellers; or

         (c) upon the termination of the Agreement Regarding Stock Acquisition.

         7.02 Procedure and Effect of  Termination.  In the event of termination
of this Agreement and abandonment of the transactions contemplated hereby by any
or all of the parties  pursuant to Section 7.01,  written  notice  thereof shall
forthwith be given to the other  parties to this  Agreement  and this  Agreement
shall  terminate and the  transactions  contemplated  hereby shall be abandoned,
without  further  action by any of the  parties  hereto.  If this  Agreement  is
terminated as provided herein:

         (a) the parties hereto will promptly redeliver to the Sellers or Buyer,
as the case may be, all documents,  work papers and other materials of any other
party relating to the transactions  contemplated hereby, whether obtained before
or after the execution hereof; and

         (b) no party hereto shall have any  liability or further  obligation to
any other party to this  Agreement  pursuant to this  Agreement  except (i) with
respect to Section 4.01, and (ii) solely with respect to  terminations  pursuant

hereunder shall have resulted in the failure of the transactions contemplated by
this Agreement to close, shall be liable for breach of contract or otherwise, to
the extent provided by law (it being  understood,  however,  that any matter set
forth on a Disclosure Supplement hereunder shall not be construed as a breach or
default of this  Agreement);  provided,  however,  that this subsection (b) (ii)
shall not be construed to limit the remedies otherwise available with respect to
such defaulting party.


                                  ARTICLE VIII
                            MISCELLANEOUS PROVISIONS

         8.01  Amendment  and  Modification.  This  Agreement  may  be  amended,
modified or supplemented only by written agreement of Buyer and Sellers.

         8.02 Waiver of Compliance;  Consents.  Except as otherwise  provided in
this Agreement, any failure of any of the parties to comply with any obligation,
covenant,  agreement or  condition  herein may be waived by the party or parties
entitled to the  benefits  thereof  only by a written  instrument  signed by the
party  granting  such  waiver,  but such waiver or failure to insist upon strict
compliance  with such  obligation,  covenant,  agreement or condition  shall not
operate as a waiver of, or estoppel  with  respect to, any  subsequent  or other
failure.  Whenever this Agreement requires or permits consent by or on behalf of
any party hereto,  such consent shall be given in writing in a manner consistent
with the  requirements  for a waiver of  compliance as set forth in this Section

         8.09 Entire  Agreement.  This Agreement,  including the Exhibits hereto
and the  agreements  (including  the  Agreement  Regarding  Stock  Acquisition),
documents,  schedules,  certificates and instruments referred to herein embodies
the entire  agreement and  understanding of the parties hereto in respect of the
transactions  contemplated  by  this  Agreement.   There  are  no  restrictions,
promises,  representations,  warranties,  covenants or undertakings,  other than
those  expressly  set forth or  referred to herein or  therein.  This  Agreement
supersedes  all prior  agreements  and  understandings  between the parties with
respect to such transactions.

         8.10  Certain Definitions.

         (a) An "affiliate" of a person shall mean any person which, directly or
indirectly,  controls,  is controlled by, or is under common control with,  such
person.

         (b) The term "control" (including,  with correlative meaning, the terms
"controlled  by" and "under common control  with"),  as used with respect to any
person, means the possession,  directly or indirectly, of the power to direct or
cause the  direction of the  management  and  policies of such  person,  whether
through the ownership of voting securities or by contract or otherwise.

         (c)  The  term  "person"  shall  mean  and  include  an  individual,  a
partnership,  a limited liability  company,  a joint venture,  a corporation,  a
trust,  an  unincorporated  organization  and a government or any  department or
agency thereof.

         (d)   The term "day" shall mean a calendar day unless otherwise stated.

         (e) The term  "subsidiary"  when used in  reference to any other person
shall mean any  corporation  of which  outstanding  securities  having  ordinary
voting power to elect a majority of the Board of  Directors of such  corporation
are owned directly or indirectly by such other person.

         (f) Whenever any representation or warranty contained in this Agreement
is qualified by reference to the  knowledge,  information  or belief of a party,
such party confirms that it has made due and diligent  inquiry as to the matters
that are the subject of such representation and warranty.

         8.11  Severability.  The parties hereto acknowledge that the provisions
of this Agreement are reasonable under the circumstances.  Any provision of this
Agreement that is prohibited or unenforceable  in any jurisdiction  shall, as to
such  jurisdiction,  be  ineffective  to  the  extent  of  such  prohibition  or
unenforceability   without  invalidating  the  remaining  provisions  hereof  or
affecting  the  validity  or  enforceability  of such  provisions  in any  other
jurisdiction.

         8.12 Specific Performance.  Each of the parties hereto acknowledges and
agrees that the other parties hereto would be  irreparably  damaged in the event
any of the  provisions of this  Agreement  are not performed in accordance  with
their specific terms or are otherwise breached. Accordingly, each of the parties
hereto agrees that they each shall be entitled to an  injunction or  injunctions
to  prevent  breaches  of the  provisions  of  this  Agreement  and  to  enforce
specifically  this Agreement and the terms and  provisions  hereof in any action
instituted  in any  court of the  United  States  or any  state  thereof  having
personal  and subject  matter  jurisdiction,  in addition to any other remedy to
which such party may be entitled at law or in equity. In the event of any action
or  proceeding  to  enforce  the terms and  conditions  of this  Agreement,  the
prevailing  party  shall be entitled to an award of  reasonable  attorneys'  and
expert's fees and costs in addition to such other relief as may be granted.

         8.13  Effectiveness.  This Agreement shall not become  effective unless
all Sellers named herein (other than Paul Post and his spouse) have executed and
delivered  this Agreement  prior to the Closing.  If Paul Post does not become a
party prior to Closing,  then the aggregate  purchase price for the Shares shall
be  reduced by the amount  set forth  opposite  his name on  Schedule 1 attached
hereto and, at the option of Buyer in its sole discretion, Buyer may assign this
Agreement to a wholly-owned  subsidiary of Buyer  immediately  prior to Closing;
provided,  however, that such assignment shall not release Buyer from any of its
obligations and liabilities under this Agreement.

         IN WITNESS  WHEREOF,  Sellers  and Buyer have  signed,  or caused  this
Agreement to be signed by their respective representatives,  as the case may be,
as of the date first above written.

                                   ARTICLE II
                  REPRESENTATIONS AND WARRANTIES OF PRINCIPALS

         As of the date hereof (except as otherwise  specified herein and except
as set  forth in the  disclosure  schedule  accompanying  this  Agreement)  (the
"Disclosure  Schedule"),  each  Principal  jointly and severally  represents and
warrants to Buyer as follows:

         2.01 Organization and Qualification.  The Company is a corporation duly
organized,  validly existing and in good standing (except in jurisdictions where
the concept of good standing does not exist) under the laws of the  jurisdiction
of its  incorporation,  has all requisite  power and authority to own, lease and
operate its properties  and to carry on its business as now being  conducted and
is duly  qualified  or  licensed  and in good  standing  to do  business in each
jurisdiction in which the property owned, leased or operated by it or the nature
of its business, as now being conducted,  makes such qualification necessary and
where the failure to so qualify,  be licensed or be in good standing would, when
taken together with all other such failures, affect materially and adversely the
financial condition or business of the Company.  Schedule 2.01 of the Disclosure
Schedule sets forth a complete list of the jurisdictions in which the Company is
qualified or licensed to do business.  Buyer has  heretofore  received  true and
complete copies of the Articles of  Incorporation  and By-laws (or other similar
charter documents), as currently in effect, of the Company.

         2.02  Capitalization; Title to Stock.

         (a) The authorized  capital stock of the Company consists of 250 shares
of common stock, no par value (the "Common Stock"), of which 155 5/12 shares are
issued  and  outstanding  as of the date  hereof  and no shares  are held in the
Company's  treasury.  Sellers are the  beneficial  and record  owners of all the
Company's  outstanding  shares of Common Stock. All of the outstanding shares of
Common Stock of the Company are duly authorized,  validly issued, fully paid and
nonassessable.  Except  for the  sale to  Buyer  as  contemplated  by the  Stock
Purchase Agreement,  there are no outstanding options,  warrants, calls or other
rights to subscribe for or purchase or acquire from the Company or Principals or
any affiliate of the Company, or any plans,  contracts or commitments  providing
for the issuance of, or the granting of rights to acquire (i) any capital  stock
of the Company or (ii) any securities  convertible  into or exchangeable for any
capital  stock of the  Company.  The Company is not  contractually  obligated to
repurchase, redeem or otherwise acquire any of its outstanding shares of capital
stock.

         (b) Each  Trust  (i) has  good and  valid  title,  beneficially  and of
record,  to the  respective  Shares set forth  opposite  its name on  Schedule 1
attached  to the  Stock  Purchase  Agreement,  free  and  clear  of  all  liens,
encumbrances  and rights of others,  (ii) is in rightful  possession of duly and
validly authorized and issued certificates evidencing its ownership of record of
the Shares,  and (iii) has full right,  power and  authority to sell,  transfer,
convey and deliver to Buyer,  in accordance with the terms of the Stock Purchase
Agreement,  good and valid  title,  beneficially  and of record,  to all of such
Shares  being  sold by such  Trust to Buyer  thereunder,  free and  clear of all
liens, encumbrances and rights of others.

         2.03  Subsidiaries.  Except  as  set  forth  on  Schedule  2.03  of the
Disclosure  Schedule,  (a) the Company has no subsidiaries,  and (b) there is no
corporation,  partnership,  joint venture or other person or entity in which the


                                      -47-
<PAGE>

Company, directly or indirectly, has, or pursuant to any agreement or agreements
has or will have,  a right or  obligation  to  acquire or make by any means,  an
interest  or  investment  (including,   without  limitation,  equity  ownership,
proprietary  interest,  loans,  guarantees  of  indebtedness  and other  similar
obligations).

         2.04  Authority  Relative  to the  Transactions  Contemplated  by  this
Agreement.  Each  Principal  has all  necessary  power,  capacity and  authority
(corporate or otherwise) to execute and deliver this Agreement and to consummate
the  transactions  contemplated  hereby.  The  execution  and  delivery  of this
Agreement and the consummation of the transactions contemplated hereby have been
duly and validly authorized on behalf of each Principal and no other proceedings
on behalf of Principals are necessary to approve and authorize the execution and
delivery of this Agreement and the consummation of the transactions contemplated
hereby.  This  Agreement  has been duly and validly  executed  and  delivered by
Principals,  and (assuming the valid execution and delivery of this Agreement by
Buyer)  constitutes  a valid and binding  agreement of  Principals,  enforceable
against  Principals  in  accordance  with  its  terms,  subject  to  bankruptcy,
insolvency,  reorganization,  moratorium and other laws of general applicability
relating to or affecting creditors' rights and to general principles of equity.

         2.05  Consents  and  Approval;  No  Violation.  Except  as set forth on
Schedule 2.05 of the Disclosure Schedule,  neither the execution and delivery of
this Agreement or the Stock Purchase Agreement by Principals and Sellers, as the
case may be, nor the  consummation by Principals or Sellers of the  transactions
contemplated  hereby or thereby,  nor compliance by any Principal or Seller with
the provisions hereof or thereof, will (i) require any Principal, the Company or
any  Seller  to  file  or  register   with,   notify,   or  obtain  any  permit,
authorization,  consent or approval of, any governmental or regulatory authority
except (A) for filings with the Federal  Trade  Commission  ("FTC") and with the

any  requirements  of federal or state  securities  laws;  (ii) conflict with or
breach  any  provision  of the  Articles  of  Incorporation,  By-laws  or  trust
agreement  (or  other  similar  governing  documents)  of  the  Company  or  any
Principal;  (iii)  violate or breach a provision of, or constitute a default (or

mortgage, indenture, deed of trust, license, franchise, permit, lease, contract,
agreement or other  instrument,  commitment or obligation to which any Principal
or the Company is a party,  or by which any  Principal  or the Company or any of
their respective  properties or assets may be bound, except for such breaches or

taken as a whole; or (iv) assuming compliance with all antitrust laws (including
the HSR Act), violate any order, writ, injunction,  decree,  judgment,  statute,

Audited Financial  Statements and Unaudited  Financial  Statements are sometimes
referred to collectively  herein as the "Financial  Statements").  The Unaudited

or any other  income not earned in the  ordinary  course of  business  except as

of any of the  foregoing  is a  party,  exclusive  of any such  agreement  which
contains  solely the provisions set forth in a form contract used by the Company
in its  ordinary  course of  business,  which  forms have been  previously  made
available  to Buyer,  or (l) any  proposed  contract  or  agreement  which  upon
acceptance of a customer or third party would create a binding  obligation  upon
the Company and which would not be cancelable without penalty within thirty (30)
days and would  involve a commitment  to pay $25,000 or more  annually (all such
oral  or  written  agreements,   contracts,  arrangements  and  commitments  are

                                      -50-
<PAGE>

copies of all such written  contracts,  commitments,  agreements or arrangements
described  on  Schedule  2.10 of the  Disclosure  Schedule  will  have been made
available  to Buyer  prior to  Closing.  To the best  knowledge  of  Principals,
Schedule 2.10 of the  Disclosure  Schedule  contains a complete list of all such
oral contracts, agreements,  commitments or arrangements and identifies which of
such  contracts are oral in nature.  Except as set forth on Schedule 2.10 of the
Disclosure Schedule, under the Material Contracts,  there are no defaults on the
part of the Company or events which, with notice or lapse of time or both, would
constitute defaults on the part of the Company, which defaults,  individually or
in  the  aggregate,  would  have  a  material  adverse  effect  on  the  assets,
liabilities,  business,  results of  operation  or  financial  condition  of the
Company  taken as a whole.  No  Principal or the Company has received any notice
from the other party to such Material Contracts of the termination or threatened
termination  thereof and no Principal  has  knowledge of the  occurrence  of any
event which would allow such other party to  terminate  such  Material  Contract
except as otherwise disclosed in the Disclosure Schedule. Except as set forth on
Schedule  2.10 of the  Disclosure  Schedule  or any other  Schedule  hereto,  no

consummation of the transactions contemplated hereby.

all  agreements  providing  for the payment of severance pay to employees of the
Company (the "Termination Benefits  Agreements").  Except as expressly indicated
on Schedule 2.10 of the Disclosure Schedule,  no event has occurred under any of
the Termination  Benefits Agreements which alone or upon the giving of notice or
the passage of time or both would obligate the Company to make any payment under
any of the Termination Benefits Agreements.

         2.11 Major Customer Contracts. Schedule 2.11 of the Disclosure Schedule
identifies the twenty  customer  agreements  that yielded the greatest amount of
revenues  to the Company for the month of  February,  1998 (the "Major  Customer

the Major Customer  Contracts  and,  except as set forth in Schedule 2.11 of the

the transactions contemplated hereby;

         (b) Prior to  Closing  Principals  will have  made  available  to Buyer

amendments thereto and all extensions and renewals thereof;

         (c) Except as set forth on Schedule 2.11 of the Disclosure Schedule, no
notice of  termination  of a Major  Customer  Contract has been  received by the
Company,  and no such  customer  has  indicated  in  writing  its  intention  to
terminate a Major Customer Contract;

         (d) There are no credits, monies or the like in excess of $1,000 due to

the Company has not  received  any written  notice of any  warranty or indemnity
claims  by any  customer  under a Major  Customer  Contract  which  has not been
settled to the satisfaction of the customer claimant;

         (f) Except as set forth on Schedule  2.11 of the  Disclosure  Schedule,
the Company has not  received  any written  notice of default  from any customer
under any of the Major Customer Contracts; and

         (g) Except as set forth in Schedule  2.11 of the  Disclosure  Schedule,
the Company has not received any notice of the filing by or against any customer
who is a  party  to a Major  Customer  Contract  of a  petition  in  bankruptcy,
assignment  for the benefit of  creditors,  a petition  seeking  reorganization,
composition, liquidation, dissolution or similar arrangement.

         2.12 Leases.  Schedule  2.12 of the  Disclosure  Schedule sets forth an
accurate  list of (a) all written  leases under which the Company is a lessee or
lessor of real  property or office  space and (b) all other  leases to which the
Company is a party (as lessee)  involving  annual  rental  payments in excess of
$12,000. All rents and additional rent due to date on such leases have been paid
and in each  case,  the  lessee  has  been in  peaceable  possession  since  the
commencement  of the original  term of such lease or  arrangement  and is not in
default  thereunder.  Except as set  forth on  Schedule  2.12 of the  Disclosure
Schedule,  there is not,  with respect to leases  referred to in clauses (a) and
(b) above, any existing default, or an event of default, or event which, with or
without notice or lapse of time or both,  would constitute a default or an event
of default, on the part of the Company.

         2.13 Proprietary  Rights;  Computer  Programs,  Databases and Software.
Schedule  2.13  of the  Disclosure  Schedule  contains  a  complete  list of all
trademarks,  trade names, assumed names, service marks, logos,  patents,  patent
applications  (both  United  States  and  foreign),   copyrights  and  copyright
registrations,  and any applications for registration and registrations therefor
presently owned or held by the Company or with respect to which the Company owns
or holds any license or other  direct or indirect  interest  (collectively,  the
"Proprietary  Rights"); and no other material Proprietary Rights are used in or,
to the knowledge of Principals, are necessary for the conduct of the business of
the Company as such business is presently conducted.  Unless otherwise indicated
in such Schedule 2.13 of the Disclosure  Schedule,  the Company owns  sufficient
right,  title and  interest in and to the  material  Proprietary  Rights for the
conduct of its business. To the knowledge of Principals, no material Proprietary
Rights used by the  Company  conflict  with or infringe  the rights of any other
person.  No  claims  have  been  asserted  by any  person  with  respect  to the
ownership,  validity,  license or use of the Proprietary Rights and no Principal
knows of any basis for such claim.  The Company  has taken  reasonable  measures
which it believes to be  appropriate  to  maintain  and protect the  Proprietary
Rights.  The Company has the right to use all material  Proprietary  Rights,  to
provide  and sell the  services  and  products  provided  and sold by it, and to
conduct  its  business  as  heretofore  conducted,  and,  except as set forth on
Schedule 2.13 of the Disclosure  Schedule,  the consummation of the transactions
contemplated hereby and by the Stock Purchase Agreement will not alter or impair
any  such  rights.  Except  as set  forth  on  Schedule  2.13 of the  Disclosure

right to use computer programs,  databases and software which are sufficient and
adequate  to  operate  the  business  of the  Company as it is  presently  being
conducted.  Except as set forth on Schedule 2.13 of the Disclosure Schedule, all
such computer programs, databases and software and the source codes thereof have

counsel  with  respect  to  probable   outcomes,   but  without  in  any  manner

the  business,  financial  condition,  results of operations or prospects of the
Company  taken as a whole or the  transactions  contemplated  hereby  and by the
Stock Purchase Agreement. The Principals do not know of any reasonable basis for
any other such claim, action, suit, proceeding or investigation.  The Company is
not  subject  to any  judgment,  order  or  decree  entered  in any  lawsuit  or

Nothing in this  Section  4.15(c)  shall  obligate  the Buyer or the  Company to

medical and dental plans prior to Closing. Each Employee shall be credited under
the vacation policy(ies) included within Buyer's Plans with all vacation accrued
by such  Employee  prior to the  Closing  Date  under the  vacation  policy(ies)
included  within the Company's plans effective prior to the Closing and not used
by such Employee prior to the Closing Date; provided, however, no Employee shall
be credited  with more than two (2) weeks of unused  vacation  accrued from plan

any amount pursuant to any such agreement,  except as expressly  provided for in
the Financial  Statements.  Principals agree that they will cause the Company to
prepare its fiscal  1997 U.S.  federal  income tax  returns  based upon the 1997
Audited  Financial  Statements.  Principals  agree that they will not permit the
Company to amend its U.S.  federal income tax returns  relating to periods prior
to January 1, 1997 in a manner that would adversely affect the Company or Buyer,
without the consent of Buyer.

         4.20  Meteognosis  S.A..  Prior to Closing,  Principals shall cause the
Company to divest itself of any ownership  interest in Meteognosis S.A., a Greek

warranties made by Principals in Article II of this Agreement or pursuant hereto
(as amended by the Disclosure  Supplements),  or any nonfulfillment,  partial or
total,  of any of the  covenants  or  agreements  made  by  Principals  in  this
Agreement to the extent not waived by Buyer in writing;  (ii) any claim, action,
suit,  proceeding  or  investigation  of  any  kind  by WSI  Corporation  or its

proceeding or  investigation  by WSI Corporation in connection with that certain

person to purchase or receive any  additional  shares of capital  stock or other
securities  of  the  Company,   including  without  limitation  any  outstanding
subscriptions,  scrip, warrants, commitments,  conversion rights, calls, options
or agreements to issue or sell additional securities of the Company.

         (b) From and after the Closing Date, Buyer shall defend,  indemnify and
hold  harmless  Principals  and their heirs,  trustees,  successors  and assigns
against  and in  respect of any and all  losses,  actions,  suits,  proceedings,
claims, liabilities, damages, causes of action, demands, assessments, judgments,
and  investigations  and any and all costs and expenses  paid to third  parties,
including without limitation,  reasonable attorneys' fees and expenses, suffered
by any of them as a result of, or arising from,  any  inaccuracy in or breach of

Article  III of this  Agreement  or  pursuant  hereto,  or any  non-fulfillment,
partial or total,  of any of the covenants or  agreements  made by Buyer in this
Agreement to the extent not waived by Principals in writing.

         (c) If a claim by a third party is made against an  indemnified  party,
and if such party  intends to seek  indemnity  with respect  thereto  under this
Article VI, the  indemnified  party shall  promptly  (and in any case within ten
days of such claim  being  made)  notify the  indemnifying  party of such claim,
provided,  however,  that the failure to so notify the indemnifying  party shall
not discharge the  indemnifying  party of its obligations  hereunder except that
the indemnifying  party shall not be liable for default judgments or any amounts
related  thereto  if the  indemnified  party  shall  not  have so  notified  the
indemnifying party.  Subject to the following  sentence,  the indemnifying party
shall have thirty days after  receipt of such notice to  undertake,  conduct and
control,  through  counsel of its own  choosing  (which is  satisfactory  to the
indemnified party) the settlement or defense thereof,  and the indemnified party
shall cooperate with it in connection  therewith (provided that the indemnifying
party shall permit the  indemnified  party to participate in such  settlement or
defense through counsel chosen by the indemnified party,  provided that the fees
and expenses of such counsel  shall be borne by the  indemnified  party) and the
indemnifying  party shall promptly  reimburse the indemnified party for the full
amount  of any loss  resulting  from  such  claim and all  related  expenses  as
incurred  by  the   indemnified   party  within   limits  of  this  Article  VI.
Notwithstanding  anything herein to the contrary,  the  indemnified  party shall
have the right to conduct and control the defense of any such claim in the event
that such claim (including a claim for equitable  relief) or the continuation of
such claim  could  reasonably  be expected to  materially  adversely  affect the
business,  results  of  operations,  prospects  or  financial  condition  of the
indemnified party or any of its affiliates,  provided, however, that (i) in such
event the  indemnified  party's  selection  of  counsel  shall be subject to the
approval of the  indemnifying  party,  which approval shall not be  unreasonably



                                      -69-
<PAGE>

withheld,  and (ii) the indemnified party may not settle any claim for an amount
in excess of  $25,000  or  consent to any  settlement  which  imposes  equitable
remedies on the indemnifying  party or its affiliates  without the prior consent
of the  indemnifying  party,  which consent shall not be unreasonably  withheld,
unless the indemnified party agrees to waive any right to indemnity  therefor by
the  indemnifying   party.  If  the  indemnifying  party  does  not  notify  the
indemnified  party  within  thirty  days after the  receipt  of the  indemnified
party's notice of a claim of indemnity hereunder that it elects to undertake the
defense thereof or if the  indemnifying  party is not reasonably  contesting the
claim in good  faith,  the  indemnified  party  shall have the right to contest,
settle or compromise the claim in the exercise of its reasonable  judgment,  and
all losses incurred by the indemnified party, including all fees and expenses of
counsel for the indemnified party, shall be paid by the indemnifying party.

         (d) Claims for  indemnification  made pursuant to Section 6.02(a)(i) or
Section 6.02(b) shall be made within a period of one year from the Closing Date.
Notwithstanding  anything  to the  contrary  in  this  Article  VI,  claims  for
indemnification  pursuant to Section 6.02(a)(ii) shall be made within five years
from the  Closing  Date,  and claims  for  indemnification  pursuant  to Section
6.02(a)(iii) may be made at any time and such  indemnification  obligation shall
survive indefinitely.

         6.03 Limitation on Indemnification.  (a) Notwithstanding the provisions
of Section  6.02(a) hereof,  Principals  shall not be obligated to indemnify and
hold   harmless   the  Buyer   Indemnitee   Group:   (i)  with  respect  to  the
indemnification contained in clause (i) of Section 6.02(a), unless and until the
aggregate  amount of all claims for which  indemnification  is sought under such
clause (i) exceeds Eighty Thousand  Dollars  ($80,000),  and then only as to the
amount  by which  aggregate  claims  thereunder  exceed  $80,000;  and (ii) with
respect to the  indemnification  contained  in clause  (ii) of Section  6.02(a),
unless and until the aggregate amount of all claims for which indemnification is
sought under such clause (ii) exceeds One Million Dollars ($1,000,000), and then
only as to the amount by which aggregate claims  thereunder  exceed  $1,000,000.
Notwithstanding  the provisions of Section  6.02(b)  hereof,  Buyer shall not be
obligated to indemnify and hold harmless  Principals  until the aggregate of all
claims for which  indemnification  is sought against Buyer under Section 6.02(b)
of this Agreement and Section 6.02(a) of the Stock Purchase  Agreement  exceeds,
in the aggregate,  Eighty Thousand  Dollars  ($80,000),  and then only as to the
amount by which aggregate claims thereunder exceed $80,000.

         (b) There shall be no limitations (either minimum thresholds or maximum
amounts) applicable to the indemnification  contained in clause (iii) of Section
6.02(a).

         (c) Subject to the last sentence of this Section 6.03(c), the aggregate
liability of Principals with respect to the indemnification  contained in clause
(i) of Section  6.02(a),  after giving  effect to the  limitations  set forth in
Section  6.03(a)  hereof,  and Buyer's  aggregate  liability with respect to the
indemnifications  contained  in Section  6.02(b) of this  Agreement  and Section
6.02(a) of the Stock Purchase Agreement,  after giving effect to the limitations
set forth in Section 6.03(a) hereof, shall not exceed $2,000,000, and each party
hereto waives (on its own behalf, and on behalf of all indemnified persons named
hereunder  benefiting  from such  party's  indemnification)  any and all rights,
claims  and  causes of  action  that it or such  persons  may have  against  the
indemnifying  party  under such  indemnification  provisions  to the extent such
rights, claims and causes of action would or could result in aggregate liability
of the indemnifying party in excess of $2,000,000.  Subject to the last sentence


                                      -70-
<PAGE>

of this Section 6.03(c),  the aggregate  liability of Principals with respect to
the  indemnification  contained in clause (ii) of Section 6.02(a),  after giving
effect to the limitations set forth in Section 6.03(a) hereof,  shall not exceed
$1,000,000,  and  Buyer  waives  (on its own  behalf  and on behalf of the Buyer
Indemnitee Group) any and all rights, claims and causes of action that it or the
Buyer  Indemnitee   Group  may  have  against   Principals  under  such  Section
6.02(a)(ii)  to the extent  such  rights,  claims and causes of action  would or
could  result in  aggregate  liability of  Principals  in excess of  $1,000,000.
Notwithstanding the foregoing  provisions of this Section 6.03(c), the aggregate
liability  of each  Trust  with  respect to the  indemnifications  contained  in
clauses (i) and (ii) of Section 6.02(a) of this Agreement and Section 6.02(b) of
the Stock Purchase Agreement shall not exceed the amount set forth opposite such
Trust's name in Schedule 1 attached to the Stock Purchase  Agreement,  being the
purchase price for such Trust's Shares.

         (d) Except for liability provided for in Section 7.02(b) hereof and the
remedy of specific  performance  provided for in Section 8.12 hereof, each party
hereto  acknowledges  and agrees that his or its sole and exclusive  remedy with
respect to any and all claims  relating to the subject  matter of this Agreement
shall be pursuant to the  indemnification  provisions  set forth in this Article
VI. In furtherance of the  foregoing,  each party waives,  to the fullest extent
permitted under applicable law, any and all rights,  claims and causes of action
that it may have  against  the  other  party  arising  under  or based  upon any
federal, state or local statute, law, ordinance,  rule or regulation, or arising
under or based upon common law or  otherwise,  except to the extent  provided in
this Article VI.

shall  terminate and the  transactions  contemplated  hereby shall be abandoned,
without  further  action by any of the  parties  hereto.  If this  Agreement  is

hereunder shall have resulted in the failure of the transactions contemplated by
this Agreement to close, shall be liable for breach of contract or otherwise, to
the extent provided by law (it being  understood,  however,  that any matter set
forth on a Disclosure Supplement hereunder shall not be construed as a breach or
default of this  Agreement);  provided,  however,  that this subsection (b) (ii)

                                  ARTICLE VIII

entitled to the  benefits  thereof  only by a written  instrument  signed by the
party  granting  such  waiver,  but such waiver or failure to insist upon strict

         8.11  Severability.  The parties hereto acknowledge that the provisions
of this Agreement are reasonable under the circumstances.  Any provision of this
Agreement that is prohibited or unenforceable  in any jurisdiction  shall, as to
such  jurisdiction,  be  ineffective  to  the  extent  of  such  prohibition  or
unenforceability   without  invalidating  the  remaining  provisions  hereof  or
affecting  the  validity  or  enforceability  of such  provisions  in any  other
jurisdiction.

         8.12 Specific Performance.  Each of the parties hereto acknowledges and
agrees that the other parties hereto would be  irreparably  damaged in the event
any of the  provisions of this  Agreement  are not performed in accordance  with
their specific terms or are otherwise breached. Accordingly, each of the parties
hereto agrees that they each shall be entitled to an  injunction or  injunctions

of action  which may accrue to Buyer  under this  Agreement,  Buyer may  proceed
against any of the  Principals  without  having  commenced  any action or having
obtained any judgment and without first attempting to collect or proceed against
any  other  Principal  or any of the  Sellers  pursuant  to the  Stock  Purchase
Agreement.
