                                  ARTICLE II

                          PURCHASE AND SALE OF STOCK

  2.1  STOCK PURCHASE.  On and subject to the terms and conditions set forth in
this Agreement, on the Closing Date, the Purchaser shall purchase from the
Seller, and the Seller shall sell and transfer to the Purchaser, all of the
shares of Common Stock owned by the Seller, free and clear of any Liens.

  2.2  PURCHASE PRICE FOR COMPANY STOCK.  The aggregate purchase price to be
paid to the Seller for the Acquired Stock (the "Purchase Price") is $4,350,000,
which amount shall be paid as follows: (a) the Purchaser shall deliver to the
Seller $3,750,000 (as adjusted pursuant to Section 2.3 below) in cash (as
adjusted, the "Cash Portion"); (b) the Purchaser shall issue to the Seller
$350,000 of Subordinated Promissory Notes in the form of Exhibit A attached
hereto (the "Subordinated Notes"); (c) the Purchaser shall issue to the Seller
97 shares of its 

                                       7

 
Class A Common Stock, par value $.01 per share (the "NES Class A Common") which
NES Class A Common, for purposes of this Agreement, shall be deemed to have a
fair market value of $1,000 per share and $97,000 in the aggregate; (d) the
Purchaser shall issue to the Seller 300 shares of its Class B Common Stock, par
value $.01 per share (the "NES Class B Common" and, collectively with the NES
Class A Common, the "NES Common Stock") which NES Class B Common, for purposes
of this Agreement, shall be deemed to have a fair market value of $10 per share
and $3,000 in the aggregate; and (e) the Purchaser shall maintain $150,000 in a
book entry account of the Purchaser (the "Holdback"). The Holdback shall be
available to satisfy any amounts owing to the Purchaser pursuant to Section 2.3
and/or Section 9.2. The Cash Portion is subject to adjustment pursuant to
Section 2.3.

  2.3  PURCHASE PRICE ADJUSTMENTS.

  (a)  Adjustment at Closing for Bonus Payment.  Notwithstanding anything herein
to the contrary, and in addition to any other adjustments set forth in this
Agreement, the Cash Portion will be reduced dollar-for-dollar by an amount equal
to the aggregate amount of any bonuses or other cash compensation paid by the
Company to Carter Wilson between December 1, 1996 and the Closing (other than
Carter Wilson's base salary paid in the Ordinary Course of Business).

  (b)  Post-Closing Adjustment for Net Equity. Within 90 days after the Closing
Date, the Purchaser and its auditors will conduct a review (the "Closing
Review") of the Net Equity as of the close of business on the day before the
Closing Date and will prepare and deliver to the Seller a computation of the Net
Equity as of the close of business on the day before the Closing Date (the
"Draft Computation").  The Purchaser and its auditors will give the Seller and
his auditors an opportunity to observe the Closing Review and will make
available to such Persons all records and work papers used in preparing the
Draft Computation.  If the Seller disagrees with the computation of the Net
Equity reflected on the Draft Computation, the Seller may, within thirty (30)
days after receipt of the Draft Computation, deliver a notice (an "Objection
Notice") to the Purchaser setting forth the Seller's calculation of the amount
of the Net Equity as of the close of business on the day before the Closing
Date.  The Purchaser and the Seller will use reasonable efforts to resolve any
disagreements as to the computation of the Net Equity, but if they do not obtain
a final resolution within 30 days after the Purchaser has received the Objection
Notice, the Purchaser and the Seller will jointly retain an independent
accounting firm of recognized national or regional standing (the "Firm") to
resolve any remaining disagreements.  If the Purchaser and the Seller are unable
to agree on the choice of the Firm, the Firm will be a "big-six" accounting firm
selected by lot (after excluding one firm designated by the Purchaser and one
firm designated by the Seller).  The Purchaser and the Seller will direct the
Firm to render a determination within 15 days of its retention and the
Purchaser, the Seller 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 Seller are unable to resolve.  The Firm's determination will be based on the
definition of Net Equity included herein.  The determination of the Firm will be
conclusive and binding upon the Purchaser and the Seller. The Purchaser and the
Seller shall bear the costs and expenses of the Firm based on the percentage
which the portion of the contested amount not awarded to each Party bears to the
amount actually contested by such Party.  The amount of the Net Equity, as
finally determined pursuant to this Section 2.3(a), is referred to herein as the
"Actual Net Equity."  If the Actual Net Equity is less than $1,350,000, the
Purchaser shall be entitled to receive from the Holdback, within two (2)
Business Days after the determination thereof, the amount of such shortfall (the
"Net Equity Shortfall"); provided, however, that if the amount then left in the
Holdback is less than the amount of the Net Equity Shortfall, the Seller shall
pay to the Purchaser, within two (2) Business Days after the determination of
the Actual Net Equity, the amount by which the Holdback is less than Net Equity
Shortfall by wire transfer or delivery of other immediately available funds.

  (c)  Post-Closing Adjustment for Leased Rental Equipment.  At the Closing, the
Company shall purchase all of the items of equipment set forth on the "Specified
Leased Equipment Schedule" attached hereto from the owners thereof (any such
item of equipment so purchased is hereinafter referred to as a "Purchased
Equipment Item").  With respect to any purchase by the Company of a Purchased
Equipment Item: (i) to the extent the purchase price actually paid by the
Company for such Purchased Equipment Item is less than the "Payoff Amount" set
forth on the Specified Leased Equipment Schedule for such Purchased Equipment
Item, the Purchaser shall pay to the Seller, on the date of purchase of such
Purchased Equipment Item, the amount of such deficit by wire transfer or
delivery of other immediately available funds, and (ii) to the extent the
purchase price actually paid by the Company for such 

                                       8

 
Purchased Equipment Item is greater than the "Payoff Amount" set forth on the
Specified Leased Equipment Schedule for such Purchased Equipment Item, the
Purchaser shall be entitled to receive from the Holdback, on the date of
determination thereof, the amount of such excess; provided, however, that if the
amount then left in the Holdback is less than the amount of such excess, the
Seller shall pay to the Purchaser, on the date of determination of such excess,
the amount by which the Holdback is less than such excess by wire transfer or
delivery of other immediately available funds.

  (d)  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 notes and accounts receivable of the Company in existence as of the Closing
(net of the $22,000 reserve for doubtful accounts) (such net amount, the
"Accounts Receivable"), which are uncollected by the Company (the "Uncollected
Receivables Amount") as of the 120th day following the Closing Date (the
"Receivables Determination Date").  If there is an Uncollected Receivables
Amount, the Purchaser shall be entitled to receive the Uncollected Receivables
Amount from the Holdback within two (2) Business Days after the Receivables
Determination Date; provided, however, that if the amount then left in the
Holdback is less than the amount of the Uncollected Receivables Amount, the
Seller 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 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 retain a collection agency, 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 Seller.

  2.4  DISTRIBUTION OF HOLDBACK. On the 130th day after the Closing Date, the
Purchaser shall pay to the Seller an amount equal to the amount of the Holdback,
if any, remaining after (i) all amounts owing to the Purchaser pursuant to
Section 2.3 have been satisfied and (ii) 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
to such 130th day, that it is entitled to receive indemnification pursuant to
Section 9.2 (each, a "Pending Claim").  As soon as practicable following final
resolution of all Pending Claims, the Purchaser shall pay to the Seller an
aggregate amount equal to the portion, if any, of the Holdback which remains
after payment of the Remaining Holdback and final resolution of all Pending
Claims.

  2.5  CLOSING TRANSACTIONS.

  (a)  Closing.  The closing of the transactions contemplated by this Agreement
(the "Closing") shall take place at the offices of Kirkland & Ellis, 200 East

18, 1997, or at such other place or on such other date as may be mutually

Agreement, the Parties shall consummate the following transactions (the "Closing

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
  the Seller contained in Article V of this Agreement or any certificate
  delivered by the Company or the Seller to the Purchaser with respect thereto

  connection with the Closing.

The Purchaser's remedy for any indemnification of Losses hereunder may be
satisfied by proceeding against Seller for all or any portion of any such Loss.
In addition, Purchaser shall have the option of recouping all or any part of 

                                       25

 
any Losses it may suffer (in lieu of seeking an equivalent amount of
indemnification to which it is entitled under this Section 9.2) by notifying the
Seller that Purchaser is reducing the principal amount outstanding under his
Subordinated Note. This shall affect the timing and amount of payments required
under such Subordinated Note in the same manner as if Purchaser had made a

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

       (i)   The Seller will be liable to the Purchaser Parties with respect to

       (ii)  The aggregate amount of all payments made by the Seller 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 Seller no later than
the Applicable Limitation Date, the Seller 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 Seller and hold the 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 the Seller in respect of any
Loss which the 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 Seller with respect thereto in connection with the
   Closing;

       (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 Seller with respect thereto in connection with the Closing;
   or

       (iii) any liability or obligation of Seller with respect to any guaranty
   executed by Seller prior to the date hereof in favor of third parties with
   respect to Indebtedness of the Company, the lease of property of the Company
   or other obligations of the Company described on the Contracts Schedule

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 the Seller gives the
   Purchaser written notice thereof within the Applicable Limitation Date; and

       (ii)  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 the Seller delivers written notice of a claim to the Purchaser no later
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 VIII, 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 

                                       26

 
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 claim 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 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 the Seller or the Purchaser as
indemnification shall be treated as adjustments to the Purchase Price.

  (h) Effective upon the Closing, the Seller hereby irrevocably waives, releases
and discharges the Company from any and all liabilities and obligations to the
Seller of any kind or nature whatsoever, whether in his capacity as Seller

                                       27

 
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 the Seller shall not seek to recover any amounts in
connection therewith or thereunder from the Company.

  SUCH CONDITIONS SHALL BE FURNISHED BY THE COMPANY TO THE HOLDER HEREOF UPON

The NES Securities shall not be transferable without the Purchaser's prior
written consent.

  10.2 CONTINUING ASSISTANCE.  Subsequent to the Closing, the 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.  In addition, to the extent not otherwise obtained by
Closing, the Seller will use best efforts to obtain (a) all consents by third
parties that are required for the transfer of the Acquired Stock to the
Purchaser, and the consummation of the other transactions contemplated hereby or
that are required in order to prevent a breach of, a default under, a
termination or modification of, or any acceleration of, any obligations under
any material contract to which the Company is a party, (b) payoff letters with
respect to all of the Company's Indebtedness outstanding as of the Closing and
(c) releases of any and all Liens (including obtaining and filing appropriate
UCC termination statements) held by third parties against property of the
Company, all on terms reasonably satisfactory to the Purchaser.

  10.3 TAX MATTERS.  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 Seller 

                                       28

 
when due, and the Seller shall, at his 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 shall, and shall cause its affiliates to, join in
the execution of any such Tax Returns and other documentation.

  10.4 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 Seller
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).

  10.5 FURTHER TRANSFERS. The 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.

  10.6 SPECIFIC PERFORMANCE.  The Seller acknowledges that the Company's
business is unique and recognizes and affirms that in the event of a breach of
this Agreement by the Seller, money damages may be inadequate and Purchaser may
have no adequate remedy at law.  Accordingly, the 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 the 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.

  10.7 TRANSITION ASSISTANCE.  The 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 business relationships with the
Company after the date of this Agreement as were maintained with the Company
prior to the date of this Agreement.

  10.8 EXPENSES.  Except as otherwise provided herein, the Seller 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 of the this
Agreement and the other agreements contemplated hereby, the performance of its
obligations hereunder and thereunder, and the consummation of the transactions
contemplated hereby and thereby (collectively, the "Transaction Expenses"); it
being understood that the Seller shall pay the fees, costs  and expenses of the
Company and that the Company shall pay any of the Seller's 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 Seller, the fees, costs
and expenses for which they are liable pursuant to this Section 10.8 may be
deducted from the Cash Purchase Price and paid directly to the Seller's legal
counsel, investment bankers and other agents and representatives.   To the
extent that the Company pays or becomes liable with respect to any Transaction
Expenses of the Company or the Seller, the Cash Purchase Price shall be reduced
dollar-for-dollar.  Notwithstanding the foregoing, the Purchaser shall pay, on
behalf of the Company, the commission owing to Grand Teton Acquisitions pursuant
to that certain Commission Agreement dated as of November 20, 1996, and no
reduction to the Cash Purchase Price shall be made as a result of such payment.

  10.9 EXCLUSIVITY.  Until this Agreement is terminated by its terms, neither
the Company nor the Seller (and neither the Company nor the Seller shall cause
or permit any Insider or agent or any other Person acting on behalf of the
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, (ii) merger
or consolidation with or into, (iii) acquisition or purchase 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 

                                       29

 
effort or attempt by any other Person to do or seek any of the foregoing. The
Company and the 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 Seller 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.

  10.10 BOOKS AND RECORDS.  Unless otherwise consented to in writing by the
Seller or the Purchaser (as the case may be), the Purchaser and the Seller 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 the Seller without first offering to
surrender to the Seller or the Purchaser such books and records or any portion
thereof of which the Seller or the Purchaser may intend to destroy, alter or
dispose.  The Purchaser and the Seller 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.

  10.11 NONCOMPETITION, NONSOLICITATION AND CONFIDENTIALITY

  (a)  Noncompetition.  In consideration of the mutual covenants provided for
herein to the Seller at the Closing, during the period beginning on the Closing
Date and ending on the fifth anniversary of the Closing Date (the "Noncompete
Period"), the Seller shall not 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 or proposes to
conduct as of the Closing Date in the State of Georgia or any other geographic
area in which the Company conducts its business as of the Closing Date, except
as expressly permitted 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.  As further consideration for the obligations of the Seller pursuant
to this Section 10.11, the Purchaser shall pay to the Seller $150,000 on the
Closing Date in the form of Subordinated Notes (the "Noncompete Payment").

  (b)  Nonsolicitation.  The Seller agrees that, during the Noncompete Period,
the Seller (i) shall not, and shall use his best efforts not to permit the
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 the Seller or any person
controlled by the Seller.

  (c)  Confidentiality.  The 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 the 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, the Seller shall notify the Purchaser promptly of the request or
requirement 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 

                                       30

 
of a waiver hereunder, the Seller is, on the advice of counsel, compelled to
disclose any Confidential Information to any tribunal or else stand liable for
contempt, the Seller may disclose the Confidential Information to the tribunal;
provided that the 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.  The Seller shall not use or permit any of his affiliates to
use the "Aerial Platforms" name or any name confusingly similar thereto in any
manner anywhere in the world after Closing.

  (e)  Remedy for Breach.  The Seller acknowledges and agrees that in the event
of a breach by the 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.


                                  ARTICLE XI

                                 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 the Seller.  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.

  11.3 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 the Seller without the prior written consent of Purchaser or by
Purchaser (except as otherwise provided in this Agreement) without the prior
written consent of the Seller.  Without limiting the generality of the
foregoing:

  (a)  Purchaser may at any time prior to the Closing, at its sole discretion,
assign, in whole or in part, its rights and obligations pursuant to this
Agreement to one or more of its wholly-owned Subsidiaries.  The Purchaser's
"wholly-owned Subsidiaries" include Subsidiaries which may be organized
subsequent to the date hereof;

  (b)  Purchaser may assign its rights under this Agreement for collateral
security purposes to any lender providing financing to Purchaser, the Company,
or any of their Affiliates and any such lender may exercise all of the rights
and remedies of the Purchaser hereunder; and

assets (whether such sale is structured as a sale of stock, a sale of assets, a
merger or otherwise).

  11.4 SEVERABILITY.  Whenever possible, each provision of this Agreement shall
be interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Agreement is held to be prohibited by or invalid
under applicable law, such provision shall be ineffective only to the extent of
such prohibition or invalidity, without invalidating the remainder of such
provisions or the remaining provisions of this Agreement.

  11.5 NO STRICT CONSTRUCTION.  The language used in this Agreement shall be
deemed to be the language chosen by the Parties to express their mutual intent,
and no rule of strict construction shall be applied against any person.

                                       32

 
  11.6  CAPTIONS.  The captions used in this Agreement are for convenience of
reference only and do not constitute a part of this Agreement and shall not be
deemed to limit, characterize or in any way affect any provision of this
Agreement, and all provisions of this Agreement shall be enforced and construed
as if no caption had been used in this Agreement.

  11.7  ENTIRE AGREEMENT.  This Agreement and the documents referred to herein
contain the entire agreement between the Parties and supersede any prior
understandings, agreements or representations by or between the Parties, written
or oral, which may have related to the subject matter hereof in any way.

each of which shall be deemed an original but all of which taken together shall
constitute one and the same instrument.

  11.9  GOVERNING LAW.  All questions concerning the construction, validity and
interpretation of this Agreement shall be governed by and construed in
accordance with the domestic laws of the State of Georgia, without giving effect
to any choice of law or conflict of law provision (whether of the State of
Georgia or any other jurisdiction) that would cause the application of the laws
of any jurisdiction other than the State of Georgia.

  11.10 PARTIES IN INTEREST.  Nothing in this Agreement, express or implied, is
intended to confer on any person other than the Parties and their respective
successors and assigns any rights or remedies under or by virtue of this
Agreement.
