         disputed items shall be submitted for resolution in accordance with the
         provisions of Section 2.5(d).  As applicable,  within five (5) business
         days following final determination of the Tax Liability Amount,  either
         (i)  Buyer  shall  pay to  Sellers  cash  equal to the  excess of their
         respective  Tax Liability  Amount over their  respective  Estimated Tax
         Liability  Amount, or (ii) Sellers shall pay to Buyer cash equal to the
         excess of their respective  Estimated Tax Liability Amount over the Tax
         Liability Amount.

                  2.5 Purchase  Price  Adjustment.  The Purchase  Price shall be
         subject to  adjustment,  if any, as  specified in this Section 2.5 (the
         "Purchase Price Adjustment").

                  (a) Within  ninety (90) days after the date hereof,  the Buyer
         shall submit to Sellers an audited  balance  sheet of the Company as of
         October 28, 1995 (the "Final Balance  Sheet").  The Final Balance Sheet
         shall be prepared by Grant Thornton,  at Buyer's expense, on a year-end
         basis and in accordance with generally accepted  accounting  principles
         ("GAAP"),  consistent  with those applied in the Financial  Statements,
         provided, however, that (i) the Final Balance Sheet

         shall not be affected by any election made under Section  338(h)(10) of
         the Code in accordance with the provisions of Section 5.8 hereof,  (ii)
         all inventory (including supplies,  raw materials,  work-in-process and
         finished  goods)  shall be valued  on a FIFO  basis at lower of cost or
         market  without  reserve for obsolete or slow-moving  inventory,  (iii)
         property,  plant and equipment  that existed at February 25, 1995 shall
         continue  to be valued at the book value as of such date and  property,
         plant and equipment purchased  subsequent to February 25, 1995 shall be
         valued  at cost and (iv)  accounts  receivable  shall be valued at face
         value without  reserve for bad debts. As set forth in Sections 3.22 and
         3.23 hereof,  respectively,  Sellers  guarantee such inventory and such
         accounts receivable.

                  (b) Sellers and Ernst & Young, at Sellers' expense, shall have
         the right to observe and review the audit by Grant  Thornton  and shall
         have access to the workpapers, schedules, memoranda and other documents
         prepared or reviewed by Grant  Thornton in connection  with such audit.
         Sellers  shall  complete  their  review  within  thirty (30) days after
         submission  to them of the Final Balance  Sheet.  If Sellers agree with
         the Final Balance Sheet, or if Sellers do not object to the same within
         such  thirty (30) day period,  then such Final  Balance  Sheet shall be
         deemed final and adopted by Sellers and Buyer.

                  (c) If Sellers  believe that any  amendment  should be made to
         the Final  Balance  Sheet they shall give the Buyer  written  notice of
         such  proposed  amendments  within the same  thirty (30) day period set
         forth in Section  2.5(b)  above.  If the Buyer agrees with the proposed
         amendments,  these  shall  be made  and the  Final  Balance  Sheet,  as
         amended,  will be deemed final and adopted by Sellers and Buyer. If any
         proposed  amendments  are  disputed  by the Buyer,  the  parties  shall
         negotiate in good faith to resolve all disputed amendments.

                  (d) If, after a period of thirty (30) days  following the date
         on which  Sellers have given the Buyer  written  notice of any proposed
         amendments,  any  such  amendments  still  remain  disputed,  then  the
         disputed items shall be referred to an independent  auditor,  who shall
         be one of Coopers & Lybrand or Deloitte & Touche, to be mutually agreed
         between  Sellers and Buyer or, failing such agreement  within seven (7)
         days  after  the  expiration  of the  thirty  (30)  day  period,  to be
         appointed at the request of either Sellers or Buyer by the President of
         the American Institute of Certified Public Accountants, the decision of
         which  independent  auditor  shall be final and binding on the parties,
         and shall be  enforceable  in a court of  competent  jurisdiction.  The
         expenses  and  fees of  such  independent  auditor  in  resolving  such
         disputes  shall be shared equally  between the Buyer and Sellers,  and,
         with respect to Sellers,  the  allocation of any such expenses and fees
         shall be made in proportion to their respective Ownership Percentages.

                  (e) Buyer shall  cause New NNE to provide to such  independent
         auditor all necessary cooperation and access to its records,  premises,
         personnel  and  auditors  in order to resolve  promptly  any dispute as
         referred to in Section 2.5(d) above.

                  (f)  Within  ten (10)  days  after the  adoption  of the Final
         Balance Sheet as final, or at the Closing, whichever date is later, the
         Purchase Price Adjustment, if any, shall be made as follows:

                                    (i) in the event that the Final Total Equity
                  of the Company as shown on the Final Balance Sheet exceeds the
                  Base Total  Equity,  then Buyer  shall pay to Sellers the full
                  amount  of  such  excess  by  wire  transfer  in   immediately
                  available  funds to such  account  as has been  designated  in
                  writing to Buyer by Sellers;

                                    (ii)  in the  event  that  the  Final  Total
                  Equity of the Company as shown on the Final  Balance  Sheet is
                  less than the Base Total  Equity,  then  Sellers  shall pay to
                  Buyer the full amount of such  shortfall  by wire  transfer in
                  immediately  available  funds  to  such  account  as has  been
                  designated in writing to Sellers by Buyer; and

                          (iii) with respect to any payment  required to be made
                  pursuant to this Section 2.5(f), such payment shall be made to
                  or by Sellers,  as the case may be, in  accordance  with their
                  respective Percentage Interests.

                  2.6 Contingent Consideration.

                  (a)  Buyer   shall   cause  New  NNE  to  pay  as   contingent
         consideration  (the  "Contingent  Consideration")  to each  Seller,  in
         three, successive annual installments (the "Installments") on the first
         business  day of  January  in each year  commencing  January,  1997 and
         ending January,  1999 (the "Installment Dates") such Seller's Ownership
         Percentage  of  $666,666.66,  subject to  adjustment  as  follows  (the
         "Annual Payment"):

                           (i) the Annual  Payment  shall be reduced by one-half
                  of the amount by which  Operating  Profits,  for the  Earn-Out
                  Year ending immediately  preceding the due date of such Annual
                  Payment, are less than $3,125,000.00;

                           (ii) the  Annual  Payment  shall not be  adjusted  if
                  Operating  Profits,  for the Earn-Out Year ending  immediately
                  preceding the due date of such Annual  Payment,  are in excess
                  of $3,124,999.99 and less than $3,325,000.01;

                           (iii)  the  Annual  Payment  shall  be  increased  by
                  one-fourth of the amount by which Operating  Profits,  for the
                  Earn-Out  Year ending  immediately  preceding  the due date of
                  such Annual Payment, exceed $3,325,000.00; and



<PAGE>



                  (iv) Interest shall be payable quarterly,  in arrears,  on the
                  first day of each  calendar  quarter  during the period ending
                  January 1,  1999,  commencing  April 1, 1995 from the  Closing
                  Date at the rate of  seven  (7%)  percent  per  annum,  on the
                  unpaid   amount,   from  time  to  time,  of  the   Contingent
                  Consideration,  based on each Annual Payment having a value of
                  $666,666.66.  As of each Installment  Date, Buyer shall adjust
                  interest  payments  hereunder to reflect any  adjustment in an
                  Annual  Payment.  From and after any default in the payment by
                  New NNE of any Annual Payment,  such interest shall accrue for
                  the default  period only at the rate of twelve  percent  (12%)
                  per annum,  compounded  monthly,  and in the event of any such
                  default,  Buyer  shall  cause  New  NNE to pay on  demand  all
                  reasonable   costs  and   expenses   incurred  by  Sellers  in
                  connection  with the collection  thereof,  including,  without
                  limitation, reasonable attorneys fees.

                           (b) If any of the events  specified  below in clauses
                  (b)(i)  through  (v) occurs and is  continuing,  the  Sellers,
                  acting  through the Seller's  Representative,  may declare the
                  unpaid Installments (valued at $666,666.66 each) together with
                  interest thereon to be immediately due and payable:

                           (i) New NNE  defaults  in any  payment  of any Annual
                  Payment or interest  thereon due under Section 2.6(a) for more
                  than ten (10) days after the date when the same  shall  become
                  due and payable;

                           (iii) Buyer or New NNE shall (i) apply for or consent
                  to  the  appointment  of a  receiver,  trustee,  custodian  or
                  liquidator of it or any of its property, (ii) admit in writing
                  its  inability to pay its debts as they  mature,  (iii) make a
                  general  assignment  for the  benefit  of  creditors,  (iv) be
                  adjudicated  a bankrupt or  insolvent  or be the subject of an
                  order for relief under Title 11 of the United  States Code, or
                  (v) file a voluntary petition in bankruptcy,  or a petition or
                  an  answer  seeking  reorganization  or  an  arrangement  with
                  creditors   or  to   take   advantage   of   any   bankruptcy,
                  reorganization,  insolvency, readjustment of debt, dissolution
                  or  liquidation  law or statute,  or an answer  admitting  the
                  material  allegations  of a petition  filed  against it in any
                  proceeding  under any such law or if corporate action shall be
                  taken for the purpose of effecting any of the foregoing;

                           (iv) an order,  judgment or decree  shall be entered,
                  without the  application,  approval or consent of the Buyer by
                  any court of  competent  jurisdiction,  approving  a  petition
                  seeking reorganization of the Buyer or New NNE or appointing a
                  receiver, trustee, custodian or liquidator of the Buyer or New

                  or New NNE, and such order,  judgment or decree shall continue
                  unstayed and in effect for any period of thirty (30) days; or

                           (v) Wayne Frerichs'  employment with New NNE shall be
                  terminated  by New  NNE  without  cause,  or,  he  shall  have
                  voluntarily  resigned  at a time  when  New  NNE  shall  be in
                  default  under  any  material   provision  of  his  employment
                  agreement with New NNE.

                                    (c) Buyer may prepay the principal amount of
                  all unpaid Installments  (valued at $666,666.66 each) in cash,
                  at any time; provided,  however, that such prepayment shall be
                  for the entire, outstanding amount thereof and for all accrued
                  and unpaid  interest  thereon  up to the date of  pre-payment,
                  without any reduction,  plus (i), in the event of a prepayment
                  other than on an  Installment  Date, the amount which would be
                  calculated  as  payable  under  Section   2.6(a)(iii)  if  the
                  cumulative  monthly  Operating  Profits  of New  NNE  for  the
                  portion of the Earn-Out  Year ending with the month  preceding
                  the  prepayment  are  annualized  to the  extent  such  amount
                  exceeds  $666,666.66,  and (ii),  if  applicable,  any  amount
                  payable under Section  2.6(a)(iii) which has not been paid for
                  a completed Earn-Out Year.

                           (d) As used in this Section 2.6, the term  "Operating
                  Profits" shall mean the operating earnings of New NNE prior to
                  giving  effect to interest,  income  taxes,  depreciation  and
                  amortization,  computed  on the  accrual  basis of  accounting
                  utilizing a FIFO costing method,  in accordance with generally
                  accepted  accounting  principles ("GAAP") (and consistent with
                  the accounting  principles applied by the Company in its prior
                  fiscal  years),  except that the  following  provisions  shall
                  govern the  computation  of  Operating  Profits of New NNE for
                  purposes of this Section 2.6:

                           (i) Any extraordinary  nonrecurring  items of gain or
                  loss or expense shall be excluded from such computation.

                           (ii) Any loss,  charge or expense  (A) not related to
                  the  ordinary  business  operations  of New NNE,  or (B) paid,
                  incurred  or  charged  in  connection  with  expansion  of the
                  business  operations  presently  conducted by the Company as a
                  result of the making of  acquisitions of new businesses or the
                  opening and staffing of new operational  facilities,  shall be
                  excluded from such computation.

                           (iii) Any charge or expense for the  amortization  of
                  goodwill  arising out of the fact that Buyer has purchased the
                  Shares  or that the  Purchase  Price is in  excess  of the net
                  worth of the Company as of the Closing Date, shall be excluded
                  from such computation.

                           (iv) In the event of an election  with respect to the
                  Company  pursuant to Section 338 of the Internal  Revenue Code
                  of 1986, as amended,  such computation shall be made as though
                  no such election had been made.

                  NNE performed  for New NNE with the prior written  approval of
                  Frerichs,  and (b) annual charges not to exceed $50,000 in the

                  services,  charges or expenses for  allocation of home office,
                  executive,  consulting, general and administrative expenses or
                  other  payments,  charges  or  expenses  of Buyer  and/or  its
                  affiliates shall be excluded from such computation.

                           (vi) To the extent that aggregate  compensation  paid
                  to individuals qualifying as plan participants under New NNE's

                  NNE and  Buyer or any  Affiliate  of Buyer  shall be deemed to
                  have  occurred  upon terms not less  favorable to New NNE than
                  the   terms   used   by   New   NNE   with   respect   to  its
                  "most-favored-customers"  for the type of  product  or service
                  being provided.

                           (viii)  Tooling costs for extrusion  dies and related
                  items  shall  be   capitalized   for  the   purposes  of  such
                  computation.

                           (ix) Except as otherwise  expressly  provided  above,
                  all amounts  determined in accordance with  subparagraphs  (i)
                  through  (viii) of this Section  2.6(b) shall be determined in
                  accordance  with  generally  accepted  accounting   principles
                  consistently applied.

                           (e)  Within  thirty  (30) days  after the end of each
                  fiscal  month  in the  Earn-Out  Period,  commencing  with the
                  fiscal  month ending in January,  1996,  Buyer shall cause New
                  NNE to  deliver  to  Sellers'  Representative,  as  defined in
                  Section 8.2 below,  the unaudited  balance sheet and statement
                  of income and  retained  earnings and of cash flows of New NNE
                  as of the  end of  such  month  and  for  the  portion  of the
                  Earn-Out Year then ended.  Such financial  statements shall be
                  prepared  in  all  material   respects   pursuant  to  and  in
                  accordance  with  generally  accepted  accounting   principles
                  applied on a  consistent  basis,  except as  specified in this
                  Section 2.6, subject to final year end adjustments.

                           (f)  Commencing  with  the  first  Earn-Out  Year and
                  continuing   until   January  1,  1999,  as  soon  as  may  be
                  practicable after the last business day of each Earn-Out Year,
                  but not  later  than  the  first  (1st)  business  day of each
                  January,  Buyer will cause Grant Thornton,  as auditor for New
                  NNE,  to  deliver  to  Sellers a  statement  setting  forth in
                  reasonable  detail its calculation of the Operating Profits of
                  New NNE for the  immediately  preceding  Earn-Out Year and the
                  adjusted  Annual  Payment and interest  thereon  (which is due
                  quarterly) to be paid to Sellers pursuant to this Section 2.6.
                  The amount of such Annual  Payment and interest  thereon to be

                  business day of January by wire  transfer of federal  funds to
                  such  Seller's  bank  account as set forth on Exhibit  2.4. If
                  within 30 days after delivery of such  statement  Sellers have
                  not given written notice to Buyer disputing such statement and
                  indicating the basis of such dispute,  Buyer shall  thereafter
                  have no further  liability  to Sellers  under this Section 2.6
                  with respect to such Earn-Out  Year. In the event Sellers give
                  Buyer  such  notice of  dispute  within  such  30-day  period,
                  Sellers  and Buyer will use their  best  efforts to settle the
                  dispute  within 30 days after the giving of such  notice.  If,
                  after a period of thirty (30) days following the date on which
                  Sellers have given the Buyer  written  notice of such dispute,
                  any  such  differences  still  remain  unresolved,   then  the
                  disputed  items shall be referred to an  independent  auditor,
                  who shall be one of Coopers & Lybrand or Deloitte & Touche, to
                  be mutually  agreed on between  Sellers and Buyer or,  failing
                  such  agreement  within seven (7) days after the expiration of
                  the thirty (30) day period,  to be appointed at the request of
                  either  Sellers  or Buyer  by the  President  of the  American
                  Institute of  Certified  Public  Accountants,  the decision of
                  which  independent  auditor  shall be final and binding on the
                  parties,  and  shall be  enforceable  in a court of  competent
                  jurisdiction.  The  expenses  and  fees  of  such  independent
                  auditor in resolving  such  disputes  shall be shared  equally
                  between the Buyer and Sellers,  and,  with respect to Sellers,
                  the  allocation of any such expenses and fees shall be made in
                  proportion to their  respective  Ownership  Percentage.  Buyer
                  shall  cause New NNE to make any  further  payments to Sellers
                  required in order to comply with such decision  within 10 days
                  after such decision is rendered,  and such  payments  shall be
                  made in the manner as provided in this Section 2.6(f).

                           (g)   Notwithstanding   anything   to  the   contrary
                  contained in this Agreement,  Frerichs shall, until the end of
                  the  Earn-Out  Period (or until such  earlier time as he shall
                  have died, become permanently  disabled,  voluntarily resigned
                  or his employment  shall have been terminated for good cause),
                  be a director and the chief executive  officer of New NNE, and
                  Buyer shall  cause him to be so elected.  If any of the events
                  set forth in the parenthetical in the preceding sentence shall
                  occur, and for so long as the Earn-Out Period has not expired,
                  the  Sellers'  Representative  shall have the right to approve
                  New NNE's  shareholders'  selection of Frerich's  successor as
                  chief executive officer of New NNE, which approval will not be
                  unreasonably  withheld.  Subject to the  ultimate  control and
                  responsibility  of the  Board of  Directors  of New NNE and of
                  Buyer as a majority  stockholder,  during the Earn-Out  Period
                  Frerichs   shall  have  the  right  to  manage  the   business
                  operations  and  affairs  of New  NNE  and  shall  direct  the
                  execution of corporate plans,  including,  without limitation,
                  the hiring,  retention or  termination  of  employees  and the
                  expansion of the  Business.  The Board of Directors of New NNE
                  shall have the authority,  subject to Frerich's right of prior
                  written approval,  to formulate  long-term corporate plans and
                  acquisitions,  to set  compensation and fringe benefits and to
                  make  commitments  for  capital   expenditures.   Buyer  shall
                  cooperate  with Frerichs in  maintaining  and  increasing  New
                  NNE's profitability.  Prior to any sale or disposal by New NNE
                  of assets other than in the ordinary course of business, Buyer
                  shall first  cause New NNE to receive  the written  consent of
                  Frerichs,  which consent may be withheld at his discretion for
                  any reason.

                                  ARTICLE III

                   REPRESENTATIONS AND WARRANTIES OF SELLERS.

                           Sellers  hereby  represent  and  warrant  to Buyer as
                  follows,  which  representations  and warranties shall be true
                  and correct as of October 28, 1995 and as of the Closing  Date
                  with respect to the representations set forth in Sections 3.1,
                  3.2. 3.3, 3.4, 3.5, 3.13 and 3.14:

                           3.1  Organization.  The Company is a corporation duly
                  organized,  validly  existing and in good  standing  under the
                  laws of the State of Massachusetts and has the corporate power
                  and authority to carry on its Business as now being conducted.
                  The  Company is duly  qualified  to do  business  as a foreign
                  corporation  and is in good standing in every  jurisdiction in
                  which   the   operation   of  the   Business   requires   such
                  qualification, except for failures, if any, to be so qualified
                  and in good standing which would not, when taken together with
                  all other  such  failures  in the  aggregate,  have a Material
                  Adverse Effect.  Sellers have,  prior to the execution of this
                  Agreement,  made available to Buyer, copies of the Articles of
                  Organization and By-laws of the Company, each in effect on the
                  date hereof.

                           3.2 Authorized Capitalization; Outstanding Stock. The
                  authorized  capital  stock of the Company  consists of 200,000
                  shares of Common Stock,  no par value per share,  of which one
                  thousand  (1,000) shares are issued and  outstanding.  Sellers
                  are the lawful owners of all right,  title and interest in and
                  to all of the  Shares,  and  have  good and  marketable  title
                  thereto free and clear of any Liens. The Shares have been duly
                  authorized,   are  validly  issued  and  are  fully  paid  and
                  non-assessable.  There are no  outstanding  rights,  warrants,
                  options  or  agreements  with  respect to any class of capital
                  stock  of  the  Company.  The  delivery  of a  certificate  or
                  certificates  representing  the Shares in the manner specified
                  in Section 2.4(a) hereof will transfer to Buyer good and valid
                  title to the  Shares,  free and clear of Liens.  Schedule  3.2
                  hereto sets forth the  Sellers'  ownership of Common Stock and
                  the Shares.

                           3.3  Subsidiaries.  The Company has no subsidiaries.

                           3.4  Authority; Binding Effect.

                           (a)  Each  Seller  has  full  power,   authority  and
                  capacity   to  execute   this   Agreement   and   perform  the
                  transactions required of him at the Closing.

                           (b) The execution and delivery by each Seller of this
                  Agreement  constitute the legal, valid and binding obligations
                  of such Seller enforceable  against him in accordance with the
                  respective terms and provisions hereof and thereof, subject to
                  general  equity  principles  and  to  applicable   bankruptcy,
                  fraudulent transfer,  insolvency,  reorganization,  moratorium
                  and other  similar laws from time to time in effect  affecting
                  the enforcement of creditors' rights generally  (regardless of
                  whether such  enforcement  is  considered  in a proceeding  in
                  equity or at law).

                           3.5 Non-Contravention.  Except as otherwise set forth
                  in Schedule 3.5 hereto,  neither the execution and delivery of
                  this  Agreement  by  Sellers  nor  the  other   documents  and

                  ordinance,   rule,  regulation,   order,  judgment  or  decree
                  applicable to the Company or the Business or (c) will conflict
                  with or constitute a default (or an event which with notice or
                  lapse of time or both,  would  constitute a default) under, or
                  will result in the termination  of, or accelerate  performance
                  required  by,  any  Material  Contract  to  which  any  of the
                  Company's  assets or properties are subject or (d) will result
                  in the  creation  of any Lien upon the stock of the Company or
                  upon any of the property or assets of the Company with respect
                  to the  Business.  Sellers  hereby  agree and shall  cause the
                  Company to agree that that certain Shareholder Agreement dated
                  as of March 4, 1992 by and among the Company and Sellers shall
                  be terminated as of the Closing Date upon the  consummation of
                  the transactions contemplated by this Agreement.

                           3.6  Financial Statements. Except as reflected on the
                  Schedules attached hereto, the Financial Statements:

         and  in  accordance  with  generally  accepted  accounting   principles
         ("GAAP") applied on a consistent basis.

         The balance sheet of the Company as of February 25, 1995 is hereinafter
         called the "Balance Sheet" and February 25, 1995 is hereinafter  called
         the "Balance Sheet Date."

                  3.7 Interim Changes.  During the period from the Balance Sheet
         Date  through and  including  October 28,  1995,  the Business has been
         operated in the ordinary course in all material respects, and except as

         Securities Act of 1933, as amended,  or applicable  state securities or
         blue sky laws.

         Purchase  Price  shall be  allocated  among the  assets as set forth in

         been  engaged  by  Sellers  or  the  Company  in  connection  with  the
         transactions contemplated by this Agreement, and Sellers, in proportion
         to their  respective  Ownership  Percentage,  will bear the cost of the

         from and against  and in respect of any  Damages,  with  respect to the
         following:

                  (i) any misrepresentation,  breach of warranty or covenant, or
         non-  fulfillment of any agreement on the part of Buyer under the terms
         of  this  Agreement  or in  any  closing  document  executed  by  Buyer
         hereunder; and

                  (ii) the operation of the Company, New NNE and the Business on
         and after the  Closing  Date,  excluding  any claims  which may be made
         against  any Seller who becomes an employee of Buyer or New NNE arising
         with  respect to any events after the Closing in  connection  with such
         employment.


                  (c)  Anything  contained  in this  Agreement  to the  contrary
         notwithstanding,  (i)  Sellers  shall not be liable for any amounts for
         which the Buyer is otherwise  entitled to  indemnification  pursuant to
         Article VII hereof or this Article VIII until the aggregate  amount for
         which Buyer is entitled  to  indemnification  under all such claims for
         indemnification  under the aforesaid  Articles in the aggregate  exceed
         One Hundred Thousand Dollars ($100,000.00) (the "Threshold"),  at which
         time  Sellers  shall be liable for any such  excess,  and (ii)  Sellers
         shall not be  required  to make  indemnification  payments  pursuant to
         Article VII hereof or this Article  VIII to the extent  indemnification
         payments  thereunder  and hereunder  would exceed in the aggregate Four
         Million Dollars ($4,000,000.00) (the "Maximum  Indemnification Amount")
         and  provided,  further,  that the maximum  aggregate  liability of the
         Sellers with respect to claims for indemnification made hereunder after
         the eighteen (18) months following the Closing Date shall be limited to
         the amount of contingent  consideration payable pursuant to Section 2.6
         hereof.  In  determining  the  foregoing  Threshold  and  in  otherwise
         determining the amount to which Buyer is entitled to assert a claim for
         indemnification  pursuant to Article VII hereof or this  Article  VIII,
         only actual losses,  net of all tax benefits,  and no  consequential or
         other special  damages or losses shall be  indemnifiable.  Both parties
         hereto waive any claim to exemplary or punitive damages.

                  (d) The  obligation  of Sellers  to  indemnify  under  Section
         8.1(a)  above shall only be with  respect to  indemnity  claims made by
         Buyer within  eighteen (18) months after the Closing Date,  except that
         indemnity  claims  with  respect to  Section  3.2,  costs and  expenses
         incurred  by New NNE in  connection  with the  termination  of Resource
         Logic as provided  in Section  3.12,  and tax  indemnity  claims  under
         Section  7.2(a),  may be made within the statute of limitations  period
         specified by applicable law. Any  indemnification  payment that becomes
         due and owing to Buyer pursuant to this Article VIII shall be satisfied
         first by off-set  against the  aggregate  amount due of the  Contingent
         Consideration,  such  off-set  to be made pro rata in  accordance  with
         Sellers' respective Ownership Percentage.

                  (e) Promptly after receipt by an indemnified  party under this
         Section 8.1 of notice of any claim or the  commencement  of any action,
         the  indemnified  party shall,  if a claim in respect  thereof is to be
         made against the indemnifying  party under this Section 8.1, notify the
         indemnifying  party in writing of the claim or the commencement of that
         action stating in reasonable  detail the nature and basis of such claim
         and a good faith  estimate  of the amount  thereof,  provided  that the
         failure to notify the indemnifying  party shall not relieve it from any
         liability which it may have to the indemnified party unless and only to
         the extent such  failure  prejudices  the  ability of the  indemnifying
         party to defend against or mitigate  damages arising out of such claim.
         If any claim  shall be brought  against an  indemnified  party,  and it
         shall notify the indemnifying  party thereof,  the  indemnifying  party
         shall be entitled  to  participate  therein,  and to assume the defense
         thereof with counsel reasonably  satisfactory to the indemnified party,
         and to settle and  compromise  any such claim or action.  After  notice
         from the indemnifying party to the indemnified party of its election to
         assume the  defense of such claim or  action,  the  indemnifying  party
         shall not be liable for other  expenses  subsequently  incurred  by the
         indemnified  party in connection  with the defense  thereof;  provided,
         however,  that if the  indemnifying  party  elects  not to assume  such
         defense,  the indemnified  party may retain counsel  satisfactory to it
         and to defend, compromise or settle such claim on behalf of and for the
         account and risk of the indemnifying  party, and the indemnifying party
         shall pay all  reasonable  fees and  expenses  of such  counsel for the
         indemnified party promptly as statements  therefore are received;  and,
         provided,  further,  that the  indemnified  party  shall not consent to
         entry of any  judgment  or  enter  into any  settlement  or  compromise
         without the written  consent of the  indemnifying  party which  consent
         shall not be  unreasonably  withheld.  Buyer and Sellers  each agree to
         render to each other such  assistance as may reasonably be requested in
         order to insure the proper  and  adequate  defense of any such claim or
         proceeding.  The indemnified  party shall also have the right to select
         its own counsel, at its own expense, to represent the indemnified party
         and to participate in the defense of such claim, as applicable.

                  8.2 Sellers' Representative.  The Sellers hereby authorize and
         direct Weener to act as Sellers' Representative and to make any and all
         decisions  to be made and to take or omit to take  any and all  actions
         which  may be  made  or be  taken  by  Sellers  under  this  Agreement,
         including,  without limitation,  making,  compromising or paying claims
         for  indemnification  as  contemplated  by  Section  8.1 and taking all
         actions with respect to the  determination  of the Tax Liability Amount
         and Final Balance Sheet. All out-of-pocket  expenses incurred by Weener
         in acting on behalf of Sellers with  respect to such  matters  shall be
         shared among all Sellers in  proportion to their  respective  Ownership
         Percentage to the extent that the amount of such expenses are not fully
         recovered from Buyer.

                  8.3 Remedies Exclusive.  The remedies provided in this Article
         VIII and Section 10.3 of this Agreement shall be the exclusive remedies
         of the parties hereto from and after the Closing in connection with any
         breach of a representation or warranty, or non-performance,  partial or
         total, or any covenant or agreement contained herein. The provisions of
         this Article VIII shall apply to claims for indemnification asserted as
         between the parties hereto as well as to third-party claims.

                  9.1 Preservation of Books and Records. Sellers acknowledge and
         agree  that from and after the  Closing,  Buyer  shall be  entitled  to
         possession of all documents,  books,  records and financial data of any
         sort relating exclusively to New NNE, the Company and the Business.  At
         all  reasonable  times after the  Closing,  Buyer shall make  available
         without cost, for inspection and/or copying by Sellers,  such books and
         records.  Such  books and  records  shall be  preserved  by Buyer for a
         period   of  at  least  six  (6)  years   after   the   Closing   Date.
         Notwithstanding  the  foregoing,  in the case of all books and  records
         relating to Taxes,  Buyer shall  maintain  such books and records until
         the later of (i) eight (8) years or (ii) the  expiration of the statute
         of limitations  of the taxable  periods to which such books and records
         relate,  including extensions to the extent notified by Sellers of such
         extensions.

                  9.2 Cooperation in Litigation. Each of Sellers and Buyer shall
         provide the other with  cooperation as may reasonably be requested,  at
         the expense of the requesting  party (unless the requesting party is to
         be  indemnified  with  respect  thereto in which case such  cooperation
         shall be given at the expense of the indemnifying party), in connection
         with the defense of any litigation whether existing on the Closing Date
         or arising  thereafter  out of, or relating to, an  occurrence or event
         happening  before,  on or after the  Closing  Date,  including  without
         limitation by making  available all books and records  relating thereto
         and all employees having Knowledge of the matters in controversy.

                  9.3 Other Cooperation.  After the Closing, each of Sellers and
         Buyer shall, and shall cause its appropriate  personnel to, provide the
         other,  at the  expense  of the  requesting  party,  in the  normal and
         customary manner with financial, accounting, tax, and other information
         requested  covering  periods of  operation  of the  Business  up to the
         Closing Date. Buyer agrees,  and shall cause New NNE and any successors
         and assigns to agree,  to timely  provide to Sellers,  but in any event
         within  thirty  (30)  days  after  Sellers'  request,  the  information
         relating to the Business up to the Closing Date, which  customarily has
         been provided to Sellers in connection  with the preparation of any and
         all returns or reports  with  respect to Taxes  required to be filed by
         Sellers with any Governmental Entity and in connection with the conduct
         of any audit,  action,  proceeding or other determinations with respect
         to Taxes;  and, in substantially the form in which such information has
         customarily  been provided in the past.  Buyer agrees,  and shall cause
         New NNE and any  successors  and assigns to agree,  without  expense to
         Sellers and upon the request of Sellers,  promptly to make available to
         Sellers all work papers and  records (or copies  thereof),  relating to
         the  Business up to the Closing  Date,  as well as the  services of any
         personnel  reasonably necessary and, to execute all necessary powers of
         attorney  to enable  Sellers to prepare and file any and all returns or
         reports  with  respect to Taxes  which  Sellers  are  required to file;
         and/or,  in  connection  with  the  conduct  of  all  audits,  actions,
         proceedings or other determinations with respect to Taxes.

                  9.4  No Other Representations. Sellers make no representations
         or warranties whatsoever, express or implied, with respect to the
         Business or condition of the Company or its assets and




<PAGE>



         properties, the transactions contemplated hereby or any related matter,
         except  for those  representations  and  warranties  contained  herein.
         Without limitation as to the foregoing, Buyer acknowledges that Sellers
         make no  representations  or  warranties  with respect to any financial
         projection  or  forecast  relating  to  the  Business.   Buyer  further
         acknowledges  that it conducted an investigation of the Company and the
         Business  prior  to the  Closing  Date  and had an  opportunity  to ask
         Sellers any questions rising from such  investigation.  With respect to
         any projection or forecast  delivered by or on behalf of the Company to
         Buyer, Buyer acknowledges that (i) there are uncertainties  inherent in
         attempting   to  make  such   projections,   (ii)  it  is  taking  full
         responsibility  for  making  its own  evaluation  of the  adequacy  and
         accuracy of all such  projections  and  forecasts  furnished  to it and
         (iii) it shall have no claim  against  Sellers or its  representatives,
         stockholders, officers, directors, employees, agents or Affiliates with
         respect thereto.


                                   ARTICLE X

                                  TERMINATION.

                  10.1  Termination.  Subject to the provisions of Section 10.2,
         if the  Closing  shall not have  occurred  by the close of  business on
         January 2, 1996,  this  Agreement may be  terminated by written  notice
         given by Buyer or Sellers to the other, provided,  however, that either
         Buyer or Sellers may, upon notice to the other parties,  terminate this
         Agreement  if all of Jeffrey J. Panek,  Frerichs  and McCrill  have not
         executed  employment  agreements  within five (5) days from the date of
         this  Agreement  with  the  Buyer  or New  NNE to be  effective  at the
         Closing. Nothing contained in this Section 10.1 shall relieve any party
         of any liability for a breach of this Agreement.

                  10.2 Cure.  Notwithstanding anything to the contrary contained
         in Section  10.1,  if Buyer  intends to  terminate  this  Agreement  on
         account of any breach or default  by  Sellers  hereunder,  Buyer  shall
         notify  Sellers and, if the Sellers shall  represent to Buyer that they
         are  diligently  seeking to cure any such  breach or  default,  Sellers
         shall have the right to postpone the Closing for a period not to exceed
         thirty  days  during  which  Sellers  shall have the right to cure such
         breach or default.

                  10.3 Specific Performance.  The obligations of the Sellers and
         Buyer under this  Agreement are unique.  If either the Sellers or Buyer
         should default in their obligations  under this Agreement,  the Sellers
         and  Buyer  acknowledge  that it would be  extremely  impracticable  to
         measure the resulting damages.  Accordingly, the Sellers and Buyer may,
         in addition to any other  available  rights or remedies,  sue in equity
         for specific performance, and hereby expressly waive the defense that a
         remedy in damages will be adequate.

         party to comply with any obligation,  agreement or condition  hereunder
         may only be waived in writing by the other party but such waiver  shall
         not operate as a waiver of, or estoppel with respect to, any subsequent
         or other  failure.  No failure by any party to take any action  against
         any  breach of this  Agreement  or  default  by the other  party  shall
         constitute  a waiver of such  party's  right to enforce  any  provision
         hereof or to take any such action.

         Liability  Amount, or (ii) Sellers shall pay to Buyer cash equal to the
         excess of their respective  Estimated Tax Liability Amount over the Tax
         Liability Amount.

                  2.5 Purchase  Price  Adjustment.  The Purchase  Price shall be

                  (a) Within  ninety (90) days after the date hereof,  the Buyer
         shall submit to Sellers an audited  balance  sheet of the Company as of
         October 28, 1995 (the "Final Balance  Sheet").  The Final Balance Sheet
         shall be prepared by Grant Thornton,  at Buyer's expense, on a year-end
         basis and in accordance with generally accepted  accounting  principles
         ("GAAP"),  consistent  with those applied in the Financial  Statements,

         accordance  with  the  provisions  of  Section  5.8  hereof,  (ii)  all
         inventory

         (including supplies, raw materials, work-in-process and finished goods)
         shall be  valued  on a FIFO  basis at lower of cost or  market  without
         reserve for obsolete or slow-moving  inventory,  (iii) property,  plant
         and equipment that existed at July 29, 1995 shall continue to be valued
         at the book  value as of such date and  property,  plant and  equipment
         purchased  subsequent to July 29, 1995 shall be valued at cost and (iv)
         accounts  receivable  shall be valued at face value without reserve for
         bad debts. As set forth in Sections 3.22 and 3.23 hereof, respectively,
         Sellers guarantee such inventory and such accounts receivable.

                  (b) Sellers and Ernst & Young, at Sellers' expense, shall have
         the right to observe and review the audit by Grant  Thornton  and shall
         have access to the workpapers, schedules, memoranda and other documents
         prepared or reviewed by Grant  Thornton in connection  with such audit.
         Sellers  shall  complete  their  review  within  thirty (30) days after
         submission  to them of the Final Balance  Sheet.  If Sellers agree with
         the Final Balance Sheet, or if Sellers do not object to the same within
         such  thirty (30) day period,  then such Final  Balance  Sheet shall be
         deemed final and adopted by Sellers and Buyer.

                  (c) If Sellers  believe that any  amendment  should be made to
         the Final  Balance  Sheet they shall give the Buyer  written  notice of
         such  proposed  amendments  within the same  thirty (30) day period set
         forth in Section  2.5(b)  above.  If the Buyer agrees with the proposed
         amendments,  these  shall  be made  and the  Final  Balance  Sheet,  as
         amended,  will be deemed final and adopted by Sellers and Buyer. If any
         proposed  amendments  are  disputed  by the Buyer,  the  parties  shall
         negotiate in good faith to resolve all disputed amendments.

                  (d) If, after a period of thirty (30) days  following the date
         on which  Sellers have given the Buyer  written  notice of any proposed
         amendments,  any  such  amendments  still  remain  disputed,  then  the
         disputed items shall be referred to an independent  auditor,  who shall
         be one of Coopers & Lybrand or Deloitte & Touche, to be mutually agreed
         between  Sellers and Buyer or, failing such agreement  within seven (7)
         days  after  the  expiration  of the  thirty  (30)  day  period,  to be
         appointed at the request of either Sellers or Buyer by the President of
         the American Institute of Certified Public Accountants, the decision of
         which  independent  auditor  shall be final and binding on the parties,
         and shall be  enforceable  in a court of  competent  jurisdiction.  The
         expenses  and  fees of  such  independent  auditor  in  resolving  such
         disputes  shall be shared equally  between the Buyer and Sellers,  and,
         with respect to Sellers,  the  allocation of any such expenses and fees
         shall be made in proportion to their respective Ownership Percentages.

                  (e) Buyer shall  cause New NNE to provide to such  independent
         auditor all necessary cooperation and access to its records,  premises,
         personnel  and  auditors  in order to resolve  promptly  any dispute as
         referred to in Section 2.5(d) above.

         (f) Within ten (10) days after the adoption of the Final  Balance Sheet
         as final,  or at the  Closing,  whichever  date is later,  the Purchase
         Price Adjustment, if any, shall be made as follows:

                                    (i) in the event that the Final Total Equity
                  of the Company as shown on the Final Balance Sheet exceeds the
                  Base Total  Equity,  then Buyer  shall pay to Sellers the full
                  amount  of  such  excess  by  wire  transfer  in   immediately
                  available  funds to such  account  as has been  designated  in
                  writing to Buyer by Sellers;

                                    (ii)  in the  event  that  the  Final  Total
                  Equity of the Company as shown on the Final  Balance  Sheet is
                  less than the Base Total  Equity,  then  Sellers  shall pay to
                  Buyer the full amount of such  shortfall  by wire  transfer in
                  immediately  available  funds  to  such  account  as has  been
                  designated in writing to Sellers by Buyer; and

                          (iii)  with respect to any payment required to be made
                  pursuant to this Section 2.5(f), such payment shall be made to
                  or by Sellers,  as the case may be, in  accordance  with their
                  respective Percentage Interests.

                  2.6 Contingent Consideration.

                  (a)  Buyer   shall   cause  New  NNE  to  pay  as   contingent
         consideration  (the  "Contingent  Consideration")  to each  Seller,  in
         three, successive annual installments (the "Installments") on the first
         business  day of  January  in each year  commencing  January,  1997 and
         ending January,  1999 (the "Installment Dates") such Seller's Ownership
         Percentage  of  $666,666.66,  subject to  adjustment  as  follows  (the
         "Annual Payment"):

                           (i) the Annual  Payment  shall be reduced by one-half
                  of the amount by which  Operating  Profits,  for the  Earn-Out
                  Year ending immediately  preceding the due date of such Annual
                  Payment, are less than $3,125,000.00;

                           (ii) the  Annual  Payment  shall not be  adjusted  if
                  Operating  Profits,  for the Earn-Out Year ending  immediately
                  preceding the due date of such Annual  Payment,  are in excess
                  of $3,124,999.99 and less than $3,325,000.01;

                           (iii)  the  Annual  Payment  shall  be  increased  by
                  one-fourth of the amount by which Operating  Profits,  for the
                  Earn-Out  Year ending  immediately  preceding  the due date of
                  such Annual Payment, exceed $3,325,000.00; and




<PAGE>



                  (iv) Interest shall be payable quarterly,  in arrears,  on the
                  first day of each  calendar  quarter  during the period ending
                  January 1,  1999,  commencing  April 1, 1995 from the  Closing
                  Date at the rate of  seven  (7%)  percent  per  annum,  on the
                  unpaid   amount,   from  time  to  time,  of  the   Contingent
                  Consideration,  based on each Annual Payment having a value of
                  $666,666.66.  As of each Installment  Date, Buyer shall adjust
                  interest  payments  hereunder to reflect any  adjustment in an
                  Annual  Payment.  From and after any default in the payment by
                  New NNE of any Annual Payment,  such interest shall accrue for
                  the default  period only at the rate of twelve  percent  (12%)
                  per annum,  compounded  monthly,  and in the event of any such
                  default,  Buyer  shall  cause  New  NNE to pay on  demand  all
                  reasonable   costs  and   expenses   incurred  by  Sellers  in
                  connection  with the collection  thereof,  including,  without
                  limitation, reasonable attorneys fees.

                           (b) If any of the events  specified  below in clauses
                  (b)(i)  through  (v) occurs and is  continuing,  the  Sellers,
                  acting  through the Seller's  Representative,  may declare the
                  unpaid Installments (valued at $666,666.66 each) together with
                  interest thereon to be immediately due and payable:

                  Payment or interest  thereon due under Section 2.6(a) for more

                  its  inability to pay its debts as they  mature,  (iii) make a
                  general  assignment  for the  benefit  of  creditors,  (iv) be

                  order for relief under Title 11 of the United  States Code, or
                  (v) file a voluntary petition in bankruptcy,  or a petition or
                  an  answer  seeking  reorganization  or  an  arrangement  with
                  creditors   or  to   take   advantage   of   any   bankruptcy,

                  or  liquidation  law or statute,  or an answer  admitting  the
                  material  allegations  of a petition  filed  against it in any
                  proceeding  under any such law or if corporate action shall be
                  taken for the purpose of effecting any of the foregoing;

                           (iv) an order,  judgment or decree  shall be entered,

                  any court of  competent  jurisdiction,  approving  a  petition
                  seeking reorganization of the Buyer or New NNE or appointing a
                  receiver, trustee, custodian or liquidator of the Buyer or New

                  unstayed and in effect for any period of thirty (30) days; or

                           (v) Wayne Frerichs'  employment with New NNE shall be
                  terminated  by New  NNE  without  cause,  or,  he  shall  have
                  voluntarily  resigned  at a time  when  New  NNE  shall  be in
                  default under any material
                  provision of his employment agreement with New NNE.

                                    (c) Buyer may prepay the principal amount of
                  all unpaid Installments  (valued at $666,666.66 each) in cash,
                  at any time; provided,  however, that such prepayment shall be
                  for the entire, outstanding amount thereof and for all accrued
                  and unpaid  interest  thereon  up to the date of  pre-payment,
                  without any reduction,  plus (i), in the event of a prepayment
                  other than on an  Installment  Date, the amount which would be
                  calculated  as  payable  under  Section   2.6(a)(iii)  if  the
                  cumulative  monthly  Operating  Profits  of New  NNE  for  the
                  portion of the Earn-Out  Year ending with the month  preceding
                  the  prepayment  are  annualized  to the  extent  such  amount
                  exceeds  $666,666.66,  and (ii),  if  applicable,  any  amount
                  payable under Section  2.6(a)(iii) which has not been paid for
                  a completed Earn-Out Year.

                           (d) As used in this Section 2.6, the term  "Operating
                  Profits" shall mean the operating earnings of New NNE prior to
                  giving  effect to interest,  income  taxes,  depreciation  and
                  amortization,  computed  on the  accrual  basis of  accounting
                  utilizing a FIFO costing method,  in accordance with generally
                  accepted  accounting  principles ("GAAP") (and consistent with
                  the accounting  principles applied by the Company in its prior
                  fiscal  years),  except that the  following  provisions  shall
                  govern the  computation  of  Operating  Profits of New NNE for
                  purposes of this Section 2.6:

                           (i) Any extraordinary  nonrecurring  items of gain or
                  loss or expense shall be excluded from such computation.

                  the  ordinary  business  operations  of New NNE,  or (B) paid,
                  incurred  or  charged  in  connection  with  expansion  of the
                  business  operations  presently  conducted by the Company as a
                  result of the making of  acquisitions of new businesses or the
                  opening and staffing of new operational  facilities,  shall be
                  excluded from such computation.

                           (iii) Any charge or expense for the  amortization  of
                  goodwill  arising out of the fact that Buyer has purchased the
                  Shares  or that the  Purchase  Price is in  excess  of the net
                  worth of the Company as of the Closing Date, shall be excluded
                  from such computation.

                  Company  pursuant to Section 338 of the Internal  Revenue Code

               (v)  Except with respect to (a) third party charges billed to New
                  NNE performed  for New NNE with the prior written  approval of
                  Frerichs,  and (b) annual charges not to exceed $50,000 in the

                  other  payments,  charges  or  expenses  of Buyer  and/or  its
                  affiliates shall be excluded from such computation.

                           (vi) To the extent that aggregate  compensation  paid
                  to individuals qualifying as plan participants under New NNE's

                  annual 4% cost of living  adjustments),  such excess  shall be
                  excluded from such computation.

                           (vii) Any transaction entered into by and between New
                  NNE and  Buyer or any  Affiliate  of Buyer  shall be deemed to
                  have  occurred  upon terms not less  favorable to New NNE than
                  the   terms   used   by   New   NNE   with   respect   to  its
                  "most-favored-customers"  for the type of  product  or service
                  being provided.

                           (viii)  Tooling costs for extrusion  dies and related
                  items  shall  be   capitalized   for  the   purposes  of  such
                  computation.

                           (ix) Except as otherwise  expressly  provided  above,
                  all amounts  determined in accordance with  subparagraphs  (i)
                  through  (viii) of this Section  2.6(b) shall be determined in
                  accordance  with  generally  accepted  accounting   principles
                  consistently applied.

                           (e)  Within  thirty  (30) days  after the end of each
                  fiscal  month  in the  Earn-Out  Period,  commencing  with the
                  fiscal  month ending in January,  1996,  Buyer shall cause New
                  NNE to  deliver  to  Sellers'  Representative,  as  defined in
                  Section 8.2 below,  the unaudited  balance sheet and statement
                  of income and  retained  earnings and of cash flows of New NNE
                  as of the  end of  such  month  and  for  the  portion  of the
                  Earn-Out Year then ended.  Such financial  statements shall be
                  prepared  in  all  material   respects   pursuant  to  and  in
                  accordance  with  generally  accepted  accounting   principles
                  applied on a  consistent  basis,  except as  specified in this
                  Section 2.6, subject to final year end adjustments.

                           (f)  Commencing  with  the  first  Earn-Out  Year and
                  continuing   until   January  1,  1999,  as  soon  as  may  be
                  practicable after the last business day of each Earn-Out Year,
                  but not  later  than  the  first  (1st)  business  day of each
                  January,  Buyer will cause Grant Thornton,  as auditor for New

                  adjusted  Annual  Payment and interest  thereon  (which is due
                  quarterly) to be paid to Sellers pursuant to this Section 2.6.
                  The amount of such Annual  Payment and interest  thereon to be
                  made to each Seller shall be in  proportion  to his  Ownership
                  Percentage and shall be made on the first (1st)



<PAGE>



                  business day of January by wire  transfer of federal  funds to
                  such  Seller's  bank  account as set forth on Exhibit  2.4. If
                  within 30 days after delivery of such  statement  Sellers have
                  not given written notice to Buyer disputing such statement and
                  indicating the basis of such dispute,  Buyer shall  thereafter
                  have no further  liability  to Sellers  under this Section 2.6
                  with respect to such Earn-Out  Year. In the event Sellers give
                  Buyer  such  notice of  dispute  within  such  30-day  period,
                  Sellers  and Buyer will use their  best  efforts to settle the
                  dispute  within 30 days after the giving of such  notice.  If,
                  after a period of thirty (30) days following the date on which
                  Sellers have given the Buyer  written  notice of such dispute,
                  any  such  differences  still  remain  unresolved,   then  the
                  disputed  items shall be referred to an  independent  auditor,
                  who shall be one of Coopers & Lybrand or Deloitte & Touche, to
                  be mutually  agreed on between  Sellers and Buyer or,  failing
                  such  agreement  within seven (7) days after the expiration of
                  the thirty (30) day period,  to be appointed at the request of
                  either  Sellers  or Buyer  by the  President  of the  American
                  Institute of  Certified  Public  Accountants,  the decision of
                  which  independent  auditor  shall be final and binding on the
                  parties,  and  shall be  enforceable  in a court of  competent
                  jurisdiction.  The  expenses  and  fees  of  such  independent
                  auditor in resolving  such  disputes  shall be shared  equally
                  between the Buyer and Sellers,  and,  with respect to Sellers,
                  the  allocation of any such expenses and fees shall be made in
                  proportion to their  respective  Ownership  Percentage.  Buyer
                  shall  cause New NNE to make any  further  payments to Sellers
                  required in order to comply with such decision  within 10 days
                  after such decision is rendered,  and such  payments  shall be
                  made in the manner as provided in this Section 2.6(f).

                           (g)   Notwithstanding   anything   to  the   contrary
                  contained in this Agreement,  Frerichs shall, until the end of
                  the  Earn-Out  Period (or until such  earlier time as he shall
                  have died, become permanently  disabled,  voluntarily resigned
                  or his employment  shall have been terminated for good cause),
                  be a director and the chief executive  officer of New NNE, and
                  Buyer shall  cause him to be so elected.  If any of the events
                  set forth in the parenthetical in the preceding sentence shall
                  occur, and for so long as the Earn-Out Period has not expired,
                  the  Sellers'  Representative  shall have the right to approve
                  New NNE's  shareholders'  selection of Frerich's  successor as
                  chief executive officer of New NNE, which approval will not be
                  unreasonably  withheld.  Subject to the  ultimate  control and
                  responsibility  of the  Board of  Directors  of New NNE and of
                  Buyer as a majority  stockholder,  during the Earn-Out  Period
                  Frerichs   shall  have  the  right  to  manage  the   business
                  operations  and  affairs  of New  NNE  and  shall  direct  the
                  execution of corporate plans,  including,  without limitation,
                  the hiring,  retention or  termination  of  employees  and the
                  expansion of the  Business.  The Board of Directors of New NNE
                  shall have the authority,  subject to Frerich's right of prior
                  written approval,  to formulate  long-term corporate plans and
                  acquisitions,  to set  compensation and fringe benefits and to
                  make  commitments  for  capital   expenditures.   Buyer  shall
                  cooperate  with Frerichs in  maintaining  and  increasing  New
                  NNE's profitability.  Prior to any sale or disposal by New NNE
                  of assets other than in the ordinary course of business, Buyer
                  shall first  cause New NNE to receive  the written  consent of
                  Frerichs,  which consent may be withheld at his discretion for
                  any reason.

                                  ARTICLE III

                   REPRESENTATIONS AND WARRANTIES OF SELLERS.

                           Sellers  hereby  represent  and  warrant  to Buyer as
                  follows,  which  representations  and warranties shall be true
                  and correct as of October 28, 1995 and as of the Closing  Date
                  with respect to the representations set forth in Sections 3.1,
                  3.2. 3.3, 3.4, 3.5, 3.13 and 3.14:

                           3.1  Organization.  The Company is a corporation duly
                  organized,  validly  existing and in good  standing  under the
                  laws of the State of Florida and has the  corporate  power and
                  authority to carry on its Business as now being conducted. The
                  Company  is  duly  qualified  to  do  business  as  a  foreign
                  corporation  and is in good standing in every  jurisdiction in
                  which   the   operation   of  the   Business   requires   such
                  qualification, except for failures, if any, to be so qualified
                  and in good standing which would not, when taken together with
                  all other  such  failures  in the  aggregate,  have a Material
                  Adverse Effect.  Sellers have,  prior to the execution of this
                  Agreement,  made available to Buyer, copies of the Articles of
                  Organization and By-laws of the Company, each in effect on the
                  date hereof.

                           3.2 Authorized Capitalization; Outstanding Stock. The
                  authorized  capital  stock of the  Company  consists of 20,000
                  shares of Common Stock, $.01 par value per share, of which two
                  thousand  (2,000) shares are issued and  outstanding.  Sellers
                  are the lawful owners of all right,  title and interest in and
                  to all of the  Shares,  and  have  good and  marketable  title
                  thereto free and clear of any Liens. The Shares have been duly
                  authorized,   are  validly  issued  and  are  fully  paid  and
                  non-assessable.  There are no  outstanding  rights,  warrants,
                  options  or  agreements  with  respect to any class of capital
                  stock  of  the  Company.  The  delivery  of a  certificate  or
                  certificates  representing  the Shares in the manner specified
                  in Section 2.4(a) hereof will transfer to Buyer good and valid
                  title to the  Shares,  free and clear of Liens.  Schedule  3.2
                  hereto sets forth the  Sellers'  ownership of Common Stock and
                  the Shares.

                           3.3  Subsidiaries.  The Company has no subsidiaries.

                           3.4  Authority; Binding Effect.

                           (a)  Each  Seller  has  full  power,   authority  and
                  capacity   to  execute   this   Agreement   and   perform  the
                  transactions required of him at the Closing.

                           (b) The execution and delivery by each Seller of this
                  Agreement  constitute the legal, valid and binding obligations
                  of such Seller enforceable  against him in accordance with the
                  respective terms and provisions hereof and thereof, subject to
                  general  equity  principles  and  to  applicable   bankruptcy,
                  fraudulent transfer,  insolvency,  reorganization,  moratorium
                  and other  similar laws from time to time in effect  affecting
                  the enforcement of creditors' rights generally  (regardless of
                  whether such  enforcement  is  considered  in a proceeding  in
                  equity or at law).

                  in Schedule 3.5 hereto,  neither the execution and delivery of
                  this  Agreement  by  Sellers  nor  the  other   documents  and
                  instruments  to be executed and delivered by Sellers  pursuant

                  ordinance,   rule,  regulation,   order,  judgment  or  decree
                  applicable to the Company or the Business or (c) will conflict
                  with or constitute a default (or an event which with notice or

                  will result in the termination  of, or accelerate  performance
                  required  by,  any  Material  Contract  to  which  any  of the
                  Company's  assets or properties are subject or (d) will result
                  in the  creation  of any Lien upon the stock of the Company or
                  upon any of the property or assets of the Company with respect
                  to the  Business.  Sellers  hereby  agree and shall  cause the

                  as  of  the  Closing  Date  upon  the   consummation   of  the
                  transactions contemplated by this Agreement.

         this Section 5.8 shall be modified as necessary to reflect  adjustments
         of the Purchase Price as requred by Section 7.4.

         been  engaged  by  Sellers  or  the  Company  in  connection  with  the
         transactions contemplated by this Agreement, and Sellers, in proportion
         to their  respective  Ownership  Percentage,  will bear the cost of the
         reasonable  out-of-pocket  expenses incurred by Buyer in investigating,
         defending  against,  or appealing any such claim.  Buyer will indemnify

         8.1 of this  Agreement  with  respect to the  failure  to collect  such
         accounts   receivable   as  a  result  of  the   breach   of   Sellers'

         rights to all such uncollected accounts receivable shall be transferred
         and assigned to Sellers.

         Company  or New NNE,  as the case may be,  shall be  apportioned  among
         Sellers  and  Buyer,  in  accordance   with  each  Seller's   Ownership
         Percentage  and  with the  Buyer,  respectively,  based  on the  actual
         operations  of the Company or New NNE,  as the case may be,  during the
         portion of

         such period  ending at the close of  business on December  31, 1995 and
         the portion of such period  beginning on the day after the Closing Date
         as  determined  on the  basis  of  the  Company's  permanent  financial
         records.

                  7.3 Conveyance Taxes. Buyer agrees to assume liability for and
         to pay all sales,  transfer,  stamp, real property transfer and similar

                  7.4  Purchase  Price  Adjustments.  Sellers and Buyer agree to
         treat all payments made under  Article II,  Article VII or Article VIII
         hereof as adjustments to the Purchase Price for Tax purposes,  and such
         adjustments  shall  be made  pursuant  to the  provisions  of  Treasury
         Regulations section  1.338(b)-3T,  as well as other relevant provisions
         of section 338 of the Code and the  regulations  thereunder.  Moreover,
         Buyer shall prepare revisions to Schedule 5.8(c) hereto to reflect such
         adjustments, and shall timely forward such revised schedule to Sellers.
         Buyer and  Sellers  further  agree to timely make all filings as may be
         required by any or all of them by any relevant taxing  jurisdictions to
         reflect  such  adjustments  and to file  all tax  returns  in a  manner
         consistent with such adjustments.

                                  ARTICLE VIII

                                INDEMNIFICATION.

                  8.1  Indemnification.

                  (a)  Subject to the  provisions  of this  Agreement,  Sellers,
         severally  in  proportion  to  such   Seller's   respective   Ownership
         Percentage  agree to  indemnify  and  hold  Buyer  and its  Affiliates,
         predecessors,  successors and assigns (and their  respective  officers,
         directors,  employees  and  agents)  harmless  from and  against and in
         respect  of  any  liability,  actions,  suits,  proceedings,   demands,
         assessments,  judgments,  loss,  claim,  damages,  costs and  expenses,
         including  reasonable   attorneys'  and  experts'  fees  and  costs  of
         investigation and analysis (collectively,  "Damages"),  with respect to
         any   misrepresentation,   breach  of  warranty  or  covenant  or  non-
         fulfillment  of any agreement on the part of Sellers under the terms of
         this  Agreement  or  in  any  closing  document   executed  by  Sellers
         hereunder. With respect to any indemnity claim made against the Sellers
         hereunder,  the amount of such claim that each  Seller  shall be liable
         for  shall be  proportionate  to such  Seller's  Ownership  Percentage.
         Notwithstanding  anything in this  Agreement  to the  contrary,  if any
         Seller  breaches the  representations  and  warranties set forth in the
         second,  third and fifth  sentence of Section  3.2 hereof,  such breach
         shall be the sole responsibility of such Seller.

                  (b) Subject to the provisions of this Agreement,  Buyer agrees
         to indemnify and hold Sellers and their successors and assigns harmless
         from and against  and in respect of any  Damages,  with  respect to the
         following:




<PAGE>



         (i) any  misrepresentation,  breach of  warranty or  covenant,  or non-
         fulfillment  of any  agreement  on the part of Buyer under the terms of
         this Agreement or in any closing document  executed by Buyer hereunder;
         and

                  (ii) the operation of the Company, New NNE and the Business on
         and after the  Closing  Date,  excluding  any claims  which may be made
         against  any Seller who becomes an employee of Buyer or New NNE arising
         with  respect to any events after the Closing in  connection  with such
         employment.


                  (c)  Anything  contained  in this  Agreement  to the  contrary
         notwithstanding,  (i)  Sellers  shall not be liable for any amounts for
         which the Buyer is otherwise  entitled to  indemnification  pursuant to
         Article VII hereof or this Article VIII until the aggregate  amount for
         which Buyer is entitled  to  indemnification  under all such claims for
         indemnification  under the aforesaid  Articles in the aggregate  exceed
         One Hundred Thousand Dollars ($100,000.00) (the "Threshold"),  at which
         time  Sellers  shall be liable for any such  excess,  and (ii)  Sellers
         shall not be  required  to make  indemnification  payments  pursuant to
         Article VII hereof or this Article  VIII to the extent  indemnification
         payments  thereunder  and  hereunder  would exceed in the aggregate One
         Million Dollars ($1,000,000.00) (the "Maximum  Indemnification Amount")
         and  provided,  further,  that the maximum  aggregate  liability of the
         Sellers with respect to claims for indemnification made hereunder after
         the eighteen (18) months following the Closing Date shall be limited to
         the amount of contingent  consideration payable pursuant to Section 2.6
         hereof.  In  determining  the  foregoing  Threshold  and  in  otherwise
         determining the amount to which Buyer is entitled to assert a claim for
         indemnification  pursuant to Article VII hereof or this  Article  VIII,
         only actual losses,  net of all tax benefits,  and no  consequential or
         other special  damages or losses shall be  indemnifiable.  Both parties
         hereto   waive   any   claim  to   exemplary   or   punitive   damages.
         Notwithstanding  anything to the  contrary  set forth herein or in that
         certain Stock Purchase  Agreement (the  "Northeast  Agreement") of even
         date  herewith  between  Buyer and Sellers  pursuant to which Buyer has
         agreed to purchase capital stock of National Northeast Corporation, (i)
         in the event that  indemnity  payments are made by Sellers  pursuant to
         this Agreement,  then the maximum  indemnification  amount specified in
         the  Northeast  Agreement  shall  be  reduced  by the  amount  of  such
         indemnity  payments,  and (ii) in the event that indemnity payments are
         made by Sellers pursuant to the Northeast Agreement,  and the amount of
         such indemnity  payments in the aggregate exceeds  $3,000,000.00,  then
         the Maximum Indemnification Amount specified herein shall be reduced by
         the full amount of such excess.

                  (d) The  obligation  of Sellers  to  indemnify  under  Section
         8.1(a)  above shall only be with  respect to  indemnity  claims made by
         Buyer within eighteen (18) months after the Closing Date,
         except that  indemnity  claims with respect to Section  3.2,  costs and
         expenses  incurred by New NNE in  connection  with the  termination  of
         Resource  Logic as provided in Section 3.12,  and tax indemnity  claims
         under  Section  7.2(a),  may be made within the statute of  limitations
         period  specified by applicable law. Any  indemnification  payment that
         becomes due and owing to Buyer  pursuant to this  Article VIII shall be
         satisfied  first by off-set  against  the  aggregate  amount due of the
         Contingent  Consideration,   such  off-set  to  be  made  pro  rata  in
         accordance with Sellers' respective Ownership Percentage.

                  (e) Promptly after receipt by an indemnified  party under this
         Section 8.1 of notice of any claim or the  commencement  of any action,
         the  indemnified  party shall,  if a claim in respect  thereof is to be
         made against the indemnifying  party under this Section 8.1, notify the
         indemnifying  party in writing of the claim or the commencement of that
         action stating in reasonable  detail the nature and basis of such claim
         and a good faith  estimate  of the amount  thereof,  provided  that the
         failure to notify the indemnifying  party shall not relieve it from any
         liability which it may have to the indemnified party unless and only to
         the extent such  failure  prejudices  the  ability of the  indemnifying
         party to defend against or mitigate  damages arising out of such claim.
         If any claim  shall be brought  against an  indemnified  party,  and it
         shall notify the indemnifying  party thereof,  the  indemnifying  party
         shall be entitled  to  participate  therein,  and to assume the defense
         thereof with counsel reasonably  satisfactory to the indemnified party,
         and to settle and  compromise  any such claim or action.  After  notice
         from the indemnifying party to the indemnified party of its election to
         assume the  defense of such claim or  action,  the  indemnifying  party
         shall not be liable for other  expenses  subsequently  incurred  by the
         indemnified  party in connection  with the defense  thereof;  provided,
         however,  that if the  indemnifying  party  elects  not to assume  such
         defense,  the indemnified  party may retain counsel  satisfactory to it
         and to defend, compromise or settle such claim on behalf of and for the
         account and risk of the indemnifying  party, and the indemnifying party
         shall pay all  reasonable  fees and  expenses  of such  counsel for the
         indemnified party promptly as statements  therefore are received;  and,
         provided,  further,  that the  indemnified  party  shall not consent to
         entry of any  judgment  or  enter  into any  settlement  or  compromise
         without the written  consent of the  indemnifying  party which  consent
         shall not be  unreasonably  withheld.  Buyer and Sellers  each agree to
         render to each other such  assistance as may reasonably be requested in
         order to insure the proper  and  adequate  defense of any such claim or
         proceeding.  The indemnified  party shall also have the right to select
         its own counsel, at its own expense, to represent the indemnified party
         and to participate in the defense of such claim, as applicable.

                  8.2 Sellers' Representative.  The Sellers hereby authorize and
         direct Weener to act as Sellers' Representative and to make any and all
         decisions  to be made and to take or omit to take  any and all  actions
         which  may be  made  or be  taken  by  Sellers  under  this  Agreement,
         including,  without limitation,  making,  compromising or paying claims
         for  indemnification  as  contemplated  by  Section  8.1 and taking all
         actions with respect to the  determination  of the Tax Liability Amount
         and Final Balance Sheet. All out-of-pocket  expenses incurred by Weener
         in acting on behalf of Sellers with  respect to such  matters  shall be
         shared among all Sellers in  proportion to their  respective  Ownership
         Percentage to the extent that the amount of such expenses are not fully
         recovered from Buyer.

                  8.3 Remedies Exclusive.  The remedies provided in this Article
         VIII and Section 10.3 of this Agreement shall be the exclusive remedies
         of the parties hereto from and after the Closing in connection with any
         breach of a representation or warranty, or non-performance,  partial or
         total, or any covenant or agreement contained herein. The provisions of
         this Article VIII shall apply to claims for indemnification asserted as
         between the parties hereto as well as to third-party claims.

                                   ARTICLE IX

                      TRANSACTIONS SUBSEQUENT TO CLOSING.

                  9.1 Preservation of Books and Records. Sellers acknowledge and
         agree  that from and after the  Closing,  Buyer  shall be  entitled  to
         possession of all documents,  books,  records and financial data of any
         sort relating exclusively to New NNE, the Company and the Business.  At
         all  reasonable  times after the  Closing,  Buyer shall make  available
         without cost, for inspection and/or copying by Sellers,  such books and
         records.  Such  books and  records  shall be  preserved  by Buyer for a
         period   of  at  least  six  (6)  years   after   the   Closing   Date.
         Notwithstanding  the  foregoing,  in the case of all books and  records
         relating to Taxes,  Buyer shall  maintain  such books and records until
         the later of (i) eight (8) years or (ii) the  expiration of the statute
         of limitations  of the taxable  periods to which such books and records
         relate,  including extensions to the extent notified by Sellers of such
         extensions.

                  9.2 Cooperation in Litigation. Each of Sellers and Buyer shall
         provide the other with  cooperation as may reasonably be requested,  at
         the expense of the requesting  party (unless the requesting party is to
         be  indemnified  with  respect  thereto in which case such  cooperation
         shall be given at the expense of the indemnifying party), in connection
         with the defense of any litigation whether existing on the Closing Date
         or arising  thereafter  out of, or relating to, an  occurrence or event
         happening  before,  on or after the  Closing  Date,  including  without
         limitation by making  available all books and records  relating thereto
         and all employees having Knowledge of the matters in controversy.

                  9.3 Other Cooperation.  After the Closing, each of Sellers and
         Buyer shall, and shall cause its appropriate  personnel to, provide the
         other,  at the  expense  of the  requesting  party,  in the  normal and
         customary manner with financial, accounting, tax, and other information
         requested  covering  periods of  operation  of the  Business  up to the
         Closing Date. Buyer agrees,  and shall cause New NNE and any successors
         and assigns to agree,  to timely  provide to Sellers,  but in any event
         within  thirty  (30)  days  after  Sellers'  request,  the  information
         relating to the Business up to the Closing Date, which  customarily has
         been provided to Sellers in connection  with the preparation of any and
         all returns or reports  with  respect to Taxes  required to be filed by
         Sellers with any Governmental Entity and in connection with the conduct
         of any audit,  action,  proceeding or other determinations with respect
         to Taxes;  and, in substantially the form in which such information has
         customarily  been provided in the past.  Buyer agrees,  and shall cause
         New NNE and any  successors  and assigns to agree,  without  expense to
         Sellers and upon the request of Sellers,  promptly to make available to
         Sellers all work papers and  records (or copies  thereof),  relating to
         the  Business up to the Closing  Date,  as well as the  services of any
         personnel  reasonably necessary and, to execute all necessary powers of
         attorney  to enable  Sellers to prepare and file any and all returns or
         reports  with  respect to Taxes  which  Sellers  are  required to file;
         and/or,  in  connection  with  the  conduct  of  all  audits,  actions,
         proceedings or other determinations with respect to Taxes.

                  9.4  No Other Representations. Sellers make no representations
         or warranties whatsoever,
         express or implied, with respect to the Business or condition of the 
         Company or its assets and



<PAGE>



         properties, the transactions contemplated hereby or any related matter,
         except  for those  representations  and  warranties  contained  herein.
         Without limitation as to the foregoing, Buyer acknowledges that Sellers
         make no  representations  or  warranties  with respect to any financial
         projection  or  forecast  relating  to  the  Business.   Buyer  further
         acknowledges  that it conducted an investigation of the Company and the
         Business  prior  to the  Closing  Date  and had an  opportunity  to ask
         Sellers any questions rising from such  investigation.  With respect to
         any projection or forecast  delivered by or on behalf of the Company to
         Buyer, Buyer acknowledges that (i) there are uncertainties  inherent in
         attempting   to  make  such   projections,   (ii)  it  is  taking  full
         responsibility  for  making  its own  evaluation  of the  adequacy  and
         accuracy of all such  projections  and  forecasts  furnished  to it and
         (iii) it shall have no claim  against  Sellers or its  representatives,
         stockholders, officers, directors, employees, agents or Affiliates with
         respect thereto.


                                   ARTICLE X

                                  TERMINATION.

                  10.1  Termination.  Subject to the provisions of Section 10.2,
         if the  Closing  shall not have  occurred  by the close of  business on
         January 2, 1996,  this  Agreement may be  terminated by written  notice
         given by Buyer or Sellers to the other, provided,  however, that either
         Buyer or Sellers may, upon notice to the other parties,  terminate this
         Agreement  if all of Jeffrey J. Panek,  Frerichs  and McCrill  have not
         executed  employment  agreements  within five (5) days from the date of
         this  Agreement  with  the  Buyer  or New  NNE to be  effective  at the
         Closing. Nothing contained in this Section 10.1 shall relieve any party
         of any liability for a breach of this Agreement.

                  10.2 Cure.  Notwithstanding anything to the contrary contained
         in Section  10.1,  if Buyer  intends to  terminate  this  Agreement  on
         account of any breach or default  by  Sellers  hereunder,  Buyer  shall
         notify  Sellers and, if the Sellers shall  represent to Buyer that they
         are  diligently  seeking to cure any such  breach or  default,  Sellers
         shall have the right to postpone the Closing for a period not to exceed
         thirty  days  during  which  Sellers  shall have the right to cure such
         breach or default.

                  10.3 Specific Performance.  The obligations of the Sellers and
         Buyer under this  Agreement are unique.  If either the Sellers or Buyer
         should default in their obligations  under this Agreement,  the Sellers
         and  Buyer  acknowledge  that it would be  extremely  impracticable  to
         measure the resulting damages.  Accordingly, the Sellers and Buyer may,
         in addition to any other  available  rights or remedies,  sue in equity
         for specific performance, and hereby expressly waive the defense that a
         remedy in damages will be adequate.

                                   ARTICLE XI

                                    GENERAL.

                  11.1  Amendment  and Waiver.  No amendment of any provision of
         this Agreement  shall in any event be effective,  unless the same shall
         be in writing  and signed by the  parties  hereto.  Any  failure of any
         party to comply with any obligation,  agreement or condition  hereunder
         may only be waived in writing by the other party but such waiver  shall
         not operate as a waiver of, or estoppel with respect to, any subsequent
         or other  failure.  No failure by any party to take any action  against
         any  breach of this  Agreement  or  default  by the other  party  shall
         constitute  a waiver of such  party's  right to enforce  any  provision
         hereof or to take any such action.

                  11.2 Notices. Any notices or other communications  required to
         be given  pursuant to this  Agreement  shall be in writing and shall be
         deemed given:  (i) upon delivery,  if by hand;  (ii) three (3) Business

         (iii)  above  within  thirty six (36) hours  after such  transmission),
