          (a) Post-Closing Adjustment for Operating Income.  Within 90 days

Computation").  The Purchaser and its auditors will give the Representatives and

available to such Persons all records and work papers used in preparing the
Draft Computation.  If the Representatives disagree with the computation of the
Operating Income Adjustment Amount reflected on the Draft Computation, the
Representatives may, within thirty (30) days after receipt of the Draft
Computation, deliver a notice (an "Objection Notice") to the Purchaser setting

efforts to resolve any disagreements as to the computation of the Operating
Income Adjustment Amount, but if they do not obtain a final resolution within
30 days after the Purchaser has received the Objection Notice, the Purchaser and
a Representative will jointly retain an independent accounting firm of

choice of the Firm, the Firm will be a so-called "big-six" accounting firm (or
successor thereto) selected by lot (after excluding one firm designated by the
Purchaser and one firm designated by a Representative).  The Purchaser and a
Representative will direct the Firm to render a determination within 15 days of
its retention and the Purchaser, the Representatives and their respective agents
will cooperate with the Firm during its engagement.  The Firm will consider only
those items and amounts in the Draft Computation set forth in the Objection
Notice which the Purchaser and the Representatives are unable to resolve.  The
Firm's determination will be based on 

                                      -5-

 
the definition of Operating Income included herein. The determination of the
Firm will be conclusive and binding upon the Purchaser and the Sellers. The
Purchaser and the Sellers shall bear the costs and expenses of the Firm based on

Party bears to the amount actually contested by such Party. The amount of the
Operating Income Adjustment Amount, as finally determined pursuant to this

                                              ---------------------------------

by wire transfer or delivery of other immediately available funds, within two
(2) Business Days after the date on which the Actual Operating Income Adjustment
Amount is finally determined.

          (b) Accounts Receivable Adjustment.  Notwithstanding anything herein

to the contrary, and in addition to any other adjustments set forth in this
Agreement, the Purchase Price will be reduced dollar-for-dollar by the aggregate
amount of the net notes and accounts receivable of the Company in existence as
of the Closing (the "Accounts Receivable"), which are uncollected by the Company

Date (the "Receivables Determination Date").  "Accounts Receivable Write-offs"
           ------------------------------      ------------------------------ 
shall mean any accounts receivable of the Company which the Company has written
off and which are not reflected on the Company balance sheet dated as of January
9, 1998.  If there is an Uncollected Receivables Amount, the Purchaser shall be
entitled to receive the Uncollected Receivables Amount less any payment the

Company has received which is specifically designated as payment of an Accounts
Receivable Write-off (such difference, the "Uncollected Receivables Net
                                            ---------------------------
Amount"), from the Holdback within two (2) Business Days after the Receivables
Determination Date; provided, however, that if the Uncollected Receivables Net
Amount is less than zero, the Purchaser shall not be obligated to make any
payments and shall be entitled to keep amount by which the payments received on
Accounts Receivable Write-offs exceeds the Uncollected Receivables Amount.  If
the amount then left in the Holdback is less than the amount of the Uncollected
Receivables Net Amount, a Representative shall pay to the Purchaser, within two
(2) Business Days after the Receivables Determination Date, the amount by which
the Holdback is less than Uncollected Receivables Net Amount by wire transfer or
delivery of other immediately available funds.  For the purpose of determining
amounts collected by the Company with respect to the Accounts Receivable, (i) in
the absence of a bona fide dispute between an account debtor and the Company
regarding receivables of such account debtor accrued prior to the Closing Date,
all payments by an account debtor shall first be applied to the oldest
outstanding invoice due from that account debtor, and (ii) in the case of a
dispute between the Company and an account debtor with respect to a particular
invoice, all payments shall be first applied to the next oldest invoice due from
that account debtor. The Company shall not be required to bring any suit or take
any other action out of the Ordinary Course of Business to collect any of the
Accounts Receivable.  To the extent that the Company has not collected the full
amount of the Accounts Receivable and the Purchaser has been compensated
therefor in accordance with this Section, the Company shall assign any such
uncollected Accounts Receivable to the Sellers.

of the Holdback, if any, remaining after all claims of the Purchaser under
Section 9.2 which have theretofore been finally resolved have been satisfied
(the "Remaining Holdback") less any amount for which the Purchaser claims, prior

          (b) by a Representative or the Purchaser if there has been a material
misrepresentation or breach on the part of the other Party of the

                      INDEMNIFICATION AND RELATED MATTERS
                      -----------------------------------



          9.1       Survival.  All representations, warranties, covenants and
                    --------                                                 
agreements set forth in this Agreement or in any writing or certificate
delivered in connection with this Agreement shall survive the Closing Date and
the consummation of the transactions contemplated hereby and shall not be
affected by any examination made for or on behalf of any Party, the knowledge of
any of such Party's officers, directors, stockholders, employees or agents, or
the acceptance of any certificate or opinion.  Notwithstanding the foregoing, no
Party shall be entitled to recover for any Loss pursuant to Section 9.2(a)(i) or
Section 9.2(c)(i) unless written notice of a claim thereof is delivered to the
other Party prior to the Applicable Limitation Date.  For purposes of this
Agreement, the term "Applicable Limitation Date" shall mean the second
                     --------------------------                       
anniversary of the Closing Date; provided that the Applicable Limitation Date
with respect to the following Losses shall be as follows:  (i) with respect to
any Loss arising from or related to a breach of the representations and
warranties of the Company and Sellers set forth in Section 5.11 (Taxes), the
Applicable Limitation Date shall be the 30th day after expiration of the statute
of limitations (including any extensions thereto to the extent that such statute
of limitations may be tolled) applicable to the Tax which gave rise to such
Loss, (ii) with respect to any Loss arising from or related to a breach of the
representations and warranties of the Company and Sellers set forth in Section
5.23 (Environmental), the Applicable Limitation Date shall be the fifth
anniversary of the Closing Date, and (iii) with respect to any Loss arising from
or related to a breach of the representations and warranties of the Company and
Sellers set forth in Section 5.1 (Organization and Corporate Power), Section 5.2
(Authorization of Transactions), Section 5.3 (Capitalization), Section 5.5
(Absence of Conflicts), Section 5.15 (Brokerage) or Article 

                                     -28-

 
VI (Representations and Warranties with Respect to Sellers) and with respect to
any Loss arising from or related to a breach of the representations and
warranties of Purchaser set forth in Section 7.1 (Organization an Corporate
Power), 7.2 (Authorization of Transactions), 7.3 (No Violation) or 7.6
(Brokerage), there shall be no Applicable Limitation Date (i.e., such
representations and warranties shall survive forever).



           9.2      Indemnification.
                    --------------- 



          (a) Each Seller shall jointly and severally indemnify the Purchaser,
and the Company and each of their respective officers, directors, stockholders,
employees, agents, representatives, affiliates, successors and assigns
(collectively, the "Purchaser Parties") and hold each of them harmless from and
                    -----------------                                          
against and pay on behalf of or reimburse such Purchaser Parties in respect of
any Loss which any such Purchaser Party may suffer, sustain or become subject
to, as a result of or relating to:



          (i) the breach of any representation or warranty made by the Company
     or any Seller contained in Article V of this Agreement or any certificate
     delivered by the Company or any Seller to the Purchaser with respect
     thereto in connection with the Closing;



          (ii)  the breach of any representation or warranty made by such Seller
     contained in Article VI of this Agreement or any certificate delivered by
     such Seller to Purchaser with respect thereto in  connection with the
     Closing;



          (iii)  the breach of any representation, warranty (other than
     representations or warranties set forth in Articles V and VI), covenant or
     agreement made by the Company or any Seller contained in this Agreement,
     the other Transaction Documents, any Exhibit hereto or any certificate
     delivered by the Company or any Seller to the Purchaser with respect
     thereto in connection with the Closing; or



          (iv)  any product leased or sold by, or any services provided by, the
     Company or any of its Subsidiaries prior to the Closing Date, or the
     ownership, operation, or condition at any time on or prior to the Closing
     Date of the Company's and its Subsidiaries' facilities or any other
     properties and assets (whether real, personal, or mixed and whether
     tangible or intangible) in which Sellers or the Company or any Subsidiary
     has or had an interest.



The Purchaser's remedy for any indemnification of Losses hereunder may be
satisfied by proceeding against one or more Sellers individually for all or any
portion of any such Loss.  Notwithstanding the foregoing, if any such Loss
arises from a breach of such Seller's representation or warranty contained in
Article VI, Purchaser shall proceed solely against such breaching Seller for the
entire amount of such Loss.



          (b) The indemnification provided for in Section 9.2(a)(i) above is
subject to the following limitations:



          (i) Sellers will be liable to the Purchaser Parties with respect to
     claims referred to in Section 9.2(a)(i) only if Purchaser gives a
     Representative written notice thereof within the Applicable Limitation
     Date; and

                                     -29-

 
          (ii)  With respect to claims pursuant to Section 9.2(a)(i), the
     Sellers will be liable to the Purchaser Parties for Losses arising
     therefrom only if the aggregate Losses resulting to the Purchaser Parties
     from all such claims exceeds $62,500 (the "Threshold"), in which case the
                                                ---------
     Sellers will be liable for the entire amount of such Losses; and



          (iii)  The aggregate amount of all payments made by the Sellers in
     satisfaction of claims for indemnification pursuant to Section 9.2(a)(i)
     shall not exceed the Purchase Price (the "Cap").
                                               ---   



Notwithstanding any implication to the contrary contained in this Agreement, so
long as the Purchaser delivers written notice of a claim to Sellers under
Section 9.2(a)(i) no later than the Applicable Limitation Date, the Sellers
shall be required to indemnify the Purchaser Parties for all Losses (up to the
Cap) which the Purchaser Parties may incur in respect of the matters which are
the subject of such claim, regardless of when incurred.



          (c) The Purchaser shall indemnify the Sellers and hold each Seller and
its officers, directors, stockholders, employees, agents, representatives,
affiliates, successors and assigns (collectively, the "Seller Parties") harmless
                                                       --------------           
from and against and pay on behalf of or reimburse such Sellers in respect of
any Loss which any Seller Parties may suffer, sustain or become subject to, as a
result of or relating to:



          (i) the breach of any representation or warranty made by the Purchaser
     contained in Article VII of this Agreement or any certificate delivered by
     the Purchaser to the Sellers with respect thereto in connection with the
     Closing; or



          (ii)  the breach of any representation, warranty (other than
     representations or warranties set forth in Article VII), covenant or
     agreement made by the Purchaser contained in this Agreement, the other
     Transaction Documents, any Exhibit hereto or any certificate delivered by
     the Purchaser to the Sellers with respect thereto in connection with the
     Closing.



          (d) The indemnification provided for in Section 9.2(c)(i) above is
subject to the following limitations:



          (i) The Purchaser will be liable to the Seller Parties with respect to
     claims referred to in Section 9.2(c)(i) only if a Seller gives the
     Purchaser written notice thereof within the Applicable Limitation Date; and



          (ii)  With respect to claims pursuant to Section 9.2(c)(i), the
     Purchaser will be liable to the Seller Parties for Losses arising therefrom
     only if the aggregate Losses resulting to the Seller Parties from all such
     claims exceeds the Threshold, in which case the Purchaser will be liable
     for the entire amount of such Losses; and



          (iii)  The aggregate amount of all payments made by the Purchaser in
     satisfaction of claims for indemnification pursuant to Section 9.2(c)(i)
     shall not exceed the Cap.



Notwithstanding any implication to the contrary contained in this Agreement, so
long as a Representative delivers written notice of a claim to the Purchaser
under Section 9.2(a)(i) no later 

                                     -30-

 
than the Applicable Limitation Date, the Purchaser shall be required to
indemnify the Seller Parties for all Losses (up to the Cap) which the Seller
Parties may incur in respect of the matters which are the subject of such claim,
regardless of when incurred.



          (e) If a party hereto seeks indemnification under this Article IX,
such party (the "Indemnified Party") shall give written notice to the other
                 -----------------                                         
party (the "Indemnifying Party") after receiving written notice of any action,
            ------------------                                                
lawsuit, proceeding, investigation or other claim against it (if by a third
party) or discovering the liability, obligation or facts giving rise to such
claim for indemnification, describing the claim, the amount thereof (if known
and quantifiable), and the basis thereof; provided that the failure to so notify
the Indemnifying Party shall not relieve the Indemnifying Party of its or his
obligations hereunder except to the extent such failure shall have harmed the
Indemnifying Party.  In that regard, if any action, lawsuit, proceeding,
investigation or other claims shall be brought or asserted by any third party
which, if adversely determined, would entitle the Indemnified Party to indemnity
pursuant to this Article IX, the Indemnified Party shall promptly notify the
Indemnifying Party of the same in writing, specifying in detail the basis of
such claim and the facts pertaining thereto and the Indemnifying Party shall be
entitled to participate in the defense of such action, lawsuit, proceeding,
investigation or other claim giving rise to the Indemnified Party's claim for
indemnification at its expense, and at its option (subject to the limitations
set forth below) shall be entitled to appoint lead counsel of such defense with
reputable counsel reasonably acceptable to the Indemnified Party; provided that,
as a condition precedent to the Indemnifying Party's right to assume control of
such defense, it must first:



          (i) enter into an agreement with the Indemnified Party (in form and
     substance reasonably satisfactory to the Indemnified Party) pursuant to
     which the Indemnifying Party agrees to be fully responsible for all Losses
     relating to such claims and that it will provide full indemnification to
     the Indemnified Party for all Losses relating to such claim, and



          (ii) unconditionally guarantees the payment and performance of any
     liability or obligation which may arise with respect to such claim or the
     facts giving rise to such claim for indemnification, and



          (iii)  furnish the Indemnified Party with reasonable evidence that the
     Indemnifying Party is and will be able to satisfy any such liability;



and provided further that the Indemnifying Party shall not have the right to
assume control of such defense and shall pay the fees and expenses of counsel
retained by the Indemnified Party, if the claim which the Indemnifying Party
seeks to assume control (i) seeks non-monetary relief, (ii) involves criminal or
quasi-criminal allegations, (iii) involves a claim to which the Indemnified
Party reasonably believes an adverse determination would be detrimental to or
injure the Indemnified Party's reputation or future business prospects, or (iv)
involves a claim which, upon petition by the Indemnified Party, the appropriate
court rules that the Indemnifying Party failed or is failing to vigorously
prosecute or defend.



     If the Indemnifying Party is permitted to assume and control the defense
and elects to do so, the Indemnified Party shall have the right to employ
counsel separate from counsel employed by the Indemnifying Party in any such
action and to participate in the defense thereof, but the fees and expenses of
such counsel employed by the Indemnified Party shall be at the expense of the

                                     -31-

 
Indemnified Party unless (i) the employment thereof has been specifically
authorized by the Indemnifying Party in writing, or (ii) the Indemnifying Party
has been advised by counsel that a reasonable likelihood exists of a conflict of
interest between the Indemnifying Party and the Indemnified Party.



     If the Indemnifying Party shall control the defense of any such claim, the
Indemnifying Party shall obtain the prior written consent of the Indemnified
Party (which shall not be unreasonably withheld) before entering into any
settlement of a claim or ceasing to defend such claim, if pursuant to or as a
result of such settlement or cessation, injunction or other equitable relief
will be imposed against the Indemnified Party or if such settlement does not
expressly unconditionally release the Indemnified Party from all liabilities and
obligations with respect to such claim, without prejudice.



          (f) The Indemnifying Party shall pay the Indemnified Party in
immediately available funds promptly after the Indemnified Party provides the
Indemnifying Party with written notice of a claim hereunder and the Parties
reasonably agree that there is a reasonable basis for such claim.



          (g) Amounts paid to or on behalf of Sellers or Purchaser as
indemnification shall be treated as adjustments to the Purchase Price.



          (h) Effective upon the Closing, each Seller hereby irrevocably waives,
releases and discharges the Company from any and all liabilities and obligations
to such Seller of any kind or nature whatsoever, whether in his capacity as
Seller hereunder, as a stockholder, officer or director of the Company or
otherwise (including, without limitation, in respect of rights of contribution
or indemnification other than compensation as an employee of the Company), in
each case whether absolute or contingent, liquidated or unliquidated, and
whether arising hereunder or under any other agreement or understanding or
otherwise at law or equity, and each Seller shall not seek to recover any
amounts in connection therewith or thereunder from the Company.



                                   ARTICLE X

                             ADDITIONAL AGREEMENTS
                             ---------------------

          10.       Continuing Assistance.  Subsequent to the Closing, each
                    ---------------------                                  
Seller and the Purchaser (at their own cost) shall assist each other (including
making records available) in the preparation of their respective Tax Returns and
the filing and execution of Tax elections, if required, as well as any audits or
litigation that ensue as a result of the filing thereof, to the extent that such
assistance is reasonably requested.



           10.      Tax Matters.
                    ----------- 



          (a) All transfer, documentary, sales, use, stamp, registration and
other such Taxes and fees (including any penalties and interest thereon)
incurred in connection with this Agreement shall be paid by the Sellers when
due, and each Seller shall, at his or its own expense, file all necessary Tax
Returns and other documentation with respect to all such transfer, documentary,
sales, use, stamp, registration and other Taxes and fees, and if required by
applicable law, the Purchaser 

                                     -32-

 
shall, and shall cause its affiliates to, join in the execution of any such Tax
Returns and other documentation.



          (b) The Sellers shall reimburse the Purchaser for all Taxes of the
Company with respect to any period (or portion thereof) ending on or before the
Closing Date within ten days of payment by the Purchaser or the Company of such
Taxes; provided that the Sellers shall not be required to reimburse the
       --------                                                        
Purchaser for the portion of such Taxes which Sellers allocate toward the
$3,000,000 limitation of Company liabilities and obligations set forth in
Section 4(j) above.  For purposes of this Section 10.2(b), in the case of any
Taxes that are imposed on a periodic basis and are payable for a Taxable period
that includes (but does not end on) the Closing Date, the portion of such Tax
which is respect to the portion of such Taxable period ending on the Closing
Date shall (x) in the case of any Taxes other than Taxes based upon or related
to income or receipts, be deemed to be the amount of such Tax for the entire
Taxable period multiplied by a fraction the numerator of which is the number of
days in the Taxable period ending on the Closing Date and the denominator of
which is the number of days in the entire Taxable period, and (y) in the case of
any Tax based upon or related to income or receipts be deemed equal to the
amount which would be payable if the relevant Taxable period ended on the
Closing Date.



          10.3      Press Releases and Announcements.  Prior to the Closing
                    --------------------------------                       
Date, no press releases related to this Agreement and the transactions
contemplated herein, or other announcements to the employees, customers or
suppliers of the Company shall be issued without the mutual approval of all
Parties, except for any public disclosure which any Party in good faith believes
is required by law or regulation (in which case the disclosure shall be prepared
jointly by the Sellers and the Purchaser).  After the Closing Date, no press
releases related to this Agreement and the transactions contemplated herein, or
other announcements to the employees, customers or suppliers of the Company
shall be issued without the Purchaser's consent (which shall not be unreasonably
withheld).  Purchaser shall not disclose the Purchase Price in  any such press
release without the prior consent of the Sellers, except for any public
disclosure which any Party in good faith believes is required by law or
regulation (in which case the disclosure shall be prepared jointly by the
Sellers and the Purchaser).



          10.4      Further Transfers.  Each Seller shall execute and deliver
                    -----------------                                        
such further instruments of conveyance and transfer and take such additional
action as the Purchaser may reasonably request to effect, consummate, confirm or
evidence the transfer to the Purchaser of the Acquired Stock and any other
transactions contemplated hereby.



          10.5      Specific Performance.  Each Seller acknowledges that the
                    --------------------                                    
Company's business is unique and recognizes and affirms that in the event of a
breach of this Agreement by such Seller, money damages may be inadequate and
Purchaser may have no adequate remedy at law. Accordingly, each Seller agrees
that Purchaser shall have the right, in addition to any other rights and
remedies existing in its favor, to enforce its rights and such Seller's
obligations hereunder not only by an action or actions for damages but also by
an action or actions for specific performance, injunctive and/or other equitable
relief.



          10.6      Transition Assistance.  Each Seller shall not in any manner
                    ---------------------                                      
take any action which is designed, intended, or might be reasonably anticipated
to have the effect of discouraging customers, suppliers, lessors, licensors and
other business associates from maintaining the same 

                                     -33-

 
business relationships with the Company after the date of this Agreement as were

and the Purchaser shall pay all of their own fees, costs and expenses
(including, without limitation, fees, costs and expenses of legal counsel,
investment bankers, brokers or other representatives and consultants and
appraisal fees, costs and expenses) incurred in connection with the negotiation

expenses of the Company and that the Company shall pay any of Sellers' fees,
costs and expenses (including, without limitation, legal and accounting fees,
costs and expenses) arising in connection with the transactions contemplated
hereby if the transactions are not consummated.  At the request of the Sellers,
the fees, costs and expenses for which they are liable pursuant to this Section
10.7 may be deducted from the Cash Purchase Price and paid directly to the
Sellers' legal counsel, investment bankers and other agents and representatives.
To the extent that the Company pays or becomes liable with respect to any

shall cause or permit any Insider or agent or any other Person acting on behalf
of any Seller, the Company, or its Affiliates to), (a) solicit, initiate or
encourage the submission of any proposal or offer from any Person (including any
of them) relating to any (i) liquidation, dissolution or recapitalization of,

assets of or any equity interest in or (iv) similar transaction or business
combination involving the Company or (b) participate in any discussions or
negotiations regarding, furnish any information with respect to, assist or
participate in, or facilitate in any other manner any effort or attempt by any
other Person to do or seek any of the foregoing. The Company and each Seller
agrees that it will discontinue immediately any negotiations or discussion with
respect to any of the foregoing. Until this Agreement is terminated by its
terms, the Sellers and the Company shall notify the Purchaser immediately if any
Person makes any proposal, offer, inquiry or contact with respect to any of the
foregoing.



          10.9      Books and Records.  Unless otherwise consented to in writing
                    -----------------                                           
by the Sellers or the Purchaser (as the case may be), the Purchaser and the
Sellers will not, for a period of seven years following the date hereof,
destroy, alter or otherwise dispose of any of the books and records of the
Company acquired by the Purchaser hereunder or retained by any Seller without
first offering to surrender to the Sellers or the Purchaser such books and
records or any portion thereof of which the Sellers or the Purchaser may intend
to destroy, alter or dispose.  The Purchaser and the Sellers will allow the
other party's representatives, attorneys and accountants access to such books
and records, upon reasonable request for during such party's normal business
hours, for the purpose of examining and copying the same in connection with any
matter whether or not related to or arising out of this Agreement or the
transactions contemplated hereby.



           10.10    Appointment of Representative.
                    ----------------------------- 

                                     -34-

 
          (a) Powers of Attorney.  Each Seller irrevocably constitutes and
              ------------------                                          
appoints David S. Ament and Robert B. McCarty (each, a "Representative", and
                                                        --------------      
together, the "Representatives") as such Seller's true and lawful agent, proxy
               ---------------                                                
and attorney-in-fact and agent and authorizes each Representative acting for
such Seller and in such Seller's name, place and stead, in any and all
capacities to do and perform every act and thing required or permitted to be
done in connection with the transactions contemplated by this Agreement, as
fully to all intents and purposes as such Person might or could do in person,
including, without limitation:

 

          (i) determine the presence (or absence) of claims for indemnification
     against the Purchaser pursuant to Section 9.2 above;



          (ii)  deliver all notices required to be delivered by such Seller
     under this Agreement, including, without limitation, any notice of a claim
     for which indemnification is sought under Section 9.2 above;



          (iii)  receive all notices required to be delivered to such Seller
     under this Agreement, including, without limitation, any notice of a claim
     for which indemnification is sought under Section 9.2 above;



          (iv)  take any and all action on behalf of such Seller from time to
     time as a Representative may deem necessary or desirable to defend, pursue,
     resolve and/or settle claims under this Agreement, including, without
     limitation, indemnification under Section 9.2;  and



          (v) to engage and employ agents and representatives (including
     accountants, legal counsel and other professionals) and to incur such other
     expenses as he deems necessary or prudent in connection with the
     administration of the foregoing.



Each Seller grants unto said attorney-in-fact and agent full power and authority
to do and perform each and every act and thing necessary or desirable to be done
in connection with the transactions contemplated by this Agreement, as fully to
all intents and purposes as the undersigned might or could do in person, hereby
ratifying and confirming all that each Representative may lawfully do or cause
to be done by virtue hereof.  Each Seller will, by executing this Agreement
agree that such agency, proxy and power of attorney are coupled with an
interest, and are therefore irrevocable without the consent of a Representative
and shall survive the death, incapacity, or bankruptcy of such Seller.  Each
Seller acknowledges and agrees that upon execution of this Agreement, any
delivery by a Representative of any waiver, amendment, agreement, opinion,
certificate or other documents executed by a Representative or any decisions
made by a Representative pursuant to this Section 10.10, such Seller shall be
bound by such documents or decision as fully as if such Seller had executed and
delivered such documents or made such decisions.



          (b) A Representative shall not have by reason of this Agreement a
fiduciary relationship in respect of any Seller, except in respect of amounts
received on behalf of such Seller. A Representative shall not be liable to any
Seller for any action taken or omitted by him or any agent employed by him
hereunder or under any other Transaction Document, or in connection therewith,
except that a Representative shall not be relieved of any liability imposed by
law for gross negligence or willful misconduct.  A Representative shall not be
liable to Sellers for any apportionment or 

                                     -35-

 
distribution of payments made by him in good faith, and if any such
apportionment or distribution is subsequently determined to have been made in
error the sole recourse of any Seller to whom payment was due, but not made,
shall be to recover from other Sellers any payment in excess of the amount to
which they are determined to have been entitled. A Representative shall not be
required to make any inquiry concerning either the performance or observance of
any of the terms, provisions or conditions of this Agreement.



          (c) Replacement of a Representative.  Upon the death, disability or
              -------------------------------                                
incapacity of either initial Representative appointed pursuant to Section
10.10(a) above, each Seller acknowledges and agrees that such Representative's
executor, guardian or legal representative, as the case may be, shall (in
consultation with Sellers) appoint a replacement reasonably believed by such
person as capable of carrying out the duties and performing the obligations of
such Representative hereunder within thirty (30) days.  In the event that either
Representative resigns for any reason, such Representative shall (in
consultation with Sellers) select another representative to fill such vacancy.
Any substituted representative shall be deemed a Representative for all purposes
of this Agreement and the other Transaction Documents.



          (d) Actions of a Representative; Liability of a Representative.  Each
              ----------------------------------------------------------       
Seller agrees that Purchaser shall be entitled to rely on any action taken by a
Representative, on behalf of Sellers, pursuant to Section 10.10(a) above (each,
an "Authorized Action"), and that each Authorized Action shall be binding on
    -----------------                                                       
each Seller as fully as if such Seller had taken such Authorized Action.  The
Purchaser agrees that a Representative shall have no liability to the Purchaser
for any Authorized Action, except to the extent that such Authorized Action is
found by a final order of a court of competent jurisdiction to have constituted
fraud or willful misconduct.    Sellers jointly and severally agree to pay, and
to indemnify and hold harmless the Purchaser from and against any losses which
they may suffer, sustain, or become subject to, as the result of any claim by
any Person that an Authorized Action is not binding on, or enforceable against,
Sellers.  In addition, Sellers hereby release and discharge Purchaser from and
against any liability arising out of or in connection with a Representative's
failure to distribute any amounts received by a Representative on Sellers'
behalf to Sellers.



          (e) Allocation of Payments.  Subject to Section 9.2(a), whenever
              ----------------------                                      
Sellers are entitled to receive any payments hereunder or are obligated to make
any payments hereunder (including those specified in Section 9.2), each Seller
shall be entitled to receive from Purchaser or shall be obligated to pay to
Purchaser such portion of any such payment as set forth on the Schedule of
                                                               -----------
Stockholders.
- ------------ 



           10.11    NONCOMPETITION, NONSOLICITATION AND CONFIDENTIALITY.
                    --------------------------------------------------- 



          (a) Noncompetition.  In consideration of payment by the Purchaser to
              --------------                                                  
Sellers of $150,000 (allocated among Sellers in the manner documented in the
                                                                            
Schedule of Stockholders) (the "Noncompete Payment") and the mutual covenants
- ------------------------        ------------------                           
provided for herein to Sellers at the Closing, during the period beginning on
the Closing Date and ending on the fifth anniversary of the Closing Date (the
                                                                             
"Noncompete Period"), none of the Sellers shall engage (whether as an owner,
- ------------------                                                          
operator, manager, employee, officer, director, consultant, advisor,
representative or otherwise) directly or indirectly in any business that the
Company conducts as of the Closing Date in any geographic area in which the
Company conducts its business as of the Closing Date, except as expressly
permitted 

                                     -36-

 
under any employment agreement with the Company executed at the Closing as
contemplated hereunder; provided that ownership of less than 2% of the
outstanding stock of any publicly-traded corporation shall not be deemed to be
engaging solely by reason thereof in any of its businesses. The parties hereto
agree that the covenant set forth in this Section 10.11 is reasonable with
respect to its duration, geographical area and scope. If the final judgment of a
court of competent jurisdiction declares that any term or provision of this
Section 10.11(a) is invalid or unenforceable, the Parties agree that the court
making the determination of invalidity or unenforceability shall have the power
to reduce the scope, duration, or area of the term or provision, to delete
specific words or phrases, or to replace any invalid or unenforceable term or
provision with a term or provision that is valid and enforceable and that comes
closest to expressing the intention of the invalid or unenforceable term or
provision, and this Agreement shall be enforceable as so modified after the
expiration of the time within which the judgment may be appealed.



          (b) Nonsolicitation.  Each Seller agrees that, during the Noncompete
              ---------------                                                 
Period, such Seller (i) shall not, and shall use his best efforts not to permit
such Seller's affiliates to, directly or indirectly contact, approach or solicit
for the purpose of offering employment to or hiring (whether as an employee,
consultant, agent, independent contractor or otherwise) or actually hire any
person employed by the Company at any time prior to the Closing Date or during
the Noncompete Period, without the prior written consent of the Company and (ii)
shall not induce or attempt to induce any customer or other business relation of
the Company into any business relationship which might materially harm the
Company.  The term "indirectly" as used in this Section 10.11 is intended to
                    ----------                                              
mean any acts authorized or directed by or on behalf of any Seller or any person
controlled by such Seller.



          (c) Confidentiality.  Each Seller shall treat and hold as confidential
              ---------------                                                   
any information concerning the business and affairs of the Company that is not
already generally available to the public (the "Confidential Information"),
                                                ------------------------   
refrain from using any of the Confidential Information except in connection with
this Agreement, and deliver promptly to the Purchaser or destroy, at the request
and option of the Purchaser, all tangible embodiments (and all copies) of the
Confidential Information which are in his possession or under his control.  In
the event that any Seller is requested or required (by oral question or request
for information or documents in any legal proceeding, interrogatory, subpoena,
civil investigative demand, or similar process) to disclose any Confidential
Information, such Seller shall notify the Purchaser promptly of the request or
re  quirement so that the Purchaser may seek an appropriate protective order or
waive compliance with the provisions of this Section 10.11(c).  If, in the
absence of a protective order or the receipt of a waiver hereunder, any Seller
is, on the advice of counsel, compelled to disclose any Confidential Information
to any tribunal or else stand liable for contempt, such Seller may disclose the
Confiden  tial Information to the tribunal; provided that such disclosing Seller
shall use his best efforts to obtain, at the request of the Purchaser, an order
or other assurance that confidential treatment shall be accorded to such portion
of the Confidential Information required to be disclosed as the Purchaser shall
designate.



          (d) Trade Names.  No Seller shall use or permit any of his affiliates
              -----------                                                      
to use the "Genpower Pump & Equipment" name or any name confusingly similar
thereto in any manner anywhere in the world after Closing.

                                     -37-

 
          (e) Remedy for Breach.  Each Seller acknowledges and agrees that in
              -----------------                                              
the event of a breach by any Seller of any of the provisions of this Section
10.11, monetary damages shall not constitute a sufficient remedy.  Consequently,
in the event of any such breach, the Company, Purchaser and/or their respective
successors or assigns may, in addition to other rights and remedies existing in
their favor, apply to any court of law or equity of competent jurisdiction for
specific performance and/or injunctive or other relief in order to enforce or
prevent any violations of the provisions hereof, in each case without the
requirement of posting a bond or proving actual damages.



          10.12     EMPLOYEES.      Craig Anderson and Esau Quiroga shall
                    ---------                                            
continue to be employed by the Company and shall be eligible to participate
under the Company's Plans until March 8, 1998.  Pyramid, Inc. shall reimburse
the Company for any Loss incurred by the Company with respect to such employees'
employment or participation under the Company's Plans.

                                 MISCELLANEOUS
                                 -------------



          11.1      Amendment and Waiver.  This Agreement may be amended and any
                    --------------------                                        
provision of this Agreement may be waived, provided that any such amendment or
waiver shall be binding upon a Party only if such amendment or waiver is set
forth in a writing executed by Purchaser and a Representative.  No course of
dealing between or among any persons having any interest in this Agreement shall
be deemed effective to modify, amend or discharge any part of this Agreement or
any rights or obligations of any Party under or by reason of this Agreement.



          11.2      Notices.  All notices, demands and other communications
                    -------

          11.3      Binding Agreement; Assignment.  This Agreement and all of

the provisions hereof shall be binding upon and inure to the benefit of the
Parties and their respective successors and permitted assigns; provided that
neither this Agreement nor any of the rights, interests or obligations hereunder
may be assigned by any Seller without the prior written consent of Purchaser or
by Purchaser (except as otherwise provided in this Agreement) without the prior
written consent of each Seller. Without limiting the generality of the
foregoing:



          (a) Purchaser may at any time prior to the Closing, at its sole
