         (a)      Notwithstanding anything contained in this Agreement to the
                  contrary, this Agreement shall not constitute an agreement or

                  license, Lease, commitment, sales or purchase order or any



                                       10
<PAGE>   15


                  other agreement or any claim, right or benefit (for purposes
                  of this Section 2.3, an "agreement") arising thereunder or
                  resulting therefrom if any such attempted transfer or
                  assignment without the consent of any other party thereto
                  would constitute a breach thereof or would in any way
                  adversely affect the rights of the Sellers or Buyer
                  thereunder. Sellers have exercised, at Sellers' expense (and,
                  if reasonably requested by Buyer, after the Closing Date will
                  exercise, at Sellers' sole cost and expense) reasonable best
                  efforts to obtain the consent of any party or parties to any
                  such Contracts, licenses, Leases, commitments, sales orders,
                  Customer Contracts, Operations Agreements, purchase orders or
                  other agreements to the transfer or assignment thereof by
                  Sellers to Buyer in all cases in which such consent is
                  required and on terms and conditions reasonably satisfactory
                  to Buyer. If any such consent is not obtained, or if an
                  attempted assignment would be ineffective or would affect the
                  rights of Buyer or the Sellers thereunder such that Buyer
                  would not in fact receive all such rights, Sellers shall use
                  commercially reasonable efforts to perform such agreement for
                  the account of Buyer or otherwise cooperate with Buyer in any
                  arrangement reasonably necessary to provide for Buyer the
                  benefits and the corresponding obligations of any such
                  agreement, including enforcement for the benefit of Buyer of
                  any and all rights of the Sellers against the other party
                  thereto arising out of the breach, termination or cancellation
                  of such agreement by such other party or otherwise. To the
                  extent the Sellers perform under any Permit or license for the
                  benefit of Buyer pursuant to this Section 2.3 and Buyer
                  ultimately obtains such Permit or license for itself, the
                  Sellers shall, on demand by Buyer, relinquish their rights
                  under such Permit or license.

         (b)      It is expressly established and the Buyer hereby acknowledges
                  that in its normal course of business, NPC Mexico uses certain
                  assets which are imported on a temporary basis under NPC
                  Mexico's Maquiladora Program or Maquiladora License, as well
                  as under certain importation permits and manifests, and Buyer
                  will not legally be authorized to operate or in any way use
                  such assets as temporarily imported, unless Buyer obtains (i)
                  a Maquiladora Program or Maquiladora License, or any similar
                  program or regime as provided under applicable law; (ii)
                  conveys possession of such assets imported temporarily to an
                  entity in Mexico with such Maquiladora Program or Maquiladora
                  License or any similar program or license as provided under
                  applicable law, in which event it shall comply with the
                  required customs and legal documentation; or (iii) Buyer
                  imports such assets on a definitive basis. Sellers will use
                  their reasonable best efforts to cooperate in undertaking
                  either of the alternatives set forth in paragraphs (i), (ii),
                  and (iii) immediately preceding, at Buyer's sole cost and
                  expense.

         2.4 FURTHER ASSURANCES. From time to time after the Closing, Sellers
shall execute and deliver to Buyer such instruments of sale, transfer,
conveyance, assignment and delivery, and



                                       11

such consents, assurances, and other instruments as may be reasonably requested
by Buyer or its counsel in order to vest in Buyer all right, title and interest
of Sellers in and to the Subject Assets and otherwise in order to carry out the
purpose and intent of this Agreement. Sellers shall promptly transfer and
deliver to Buyer any cash or other property received by Sellers, directly or
indirectly, at any time after the Closing Date which have arisen from events
occurring after the Effective Time in respect of or relating to any Subject
Assets.

         2.5 SALE AT CLOSING DATE. The sale, transfer, assignment and delivery
by the Seller of the Subject Assets to the Buyer or its assignee shall be
consummated on the Closing Date by Documents of Conveyance and shall be
effective at the Effective Time.

         2.6 SELLER'S RECORDS. Other than records which are Excluded Assets,
Buyer shall be entitled to inspect any and all records related to the Business
or the Subject Assets retained by Sellers and obtain copies of such records (or
originals if reasonably requested by Buyer) at reasonable times and locations
and in the manner agreed to by Buyer and Seller. Seller agrees either to retain
all such records for a period of at least seven (7) years after the Closing
Date, or, at Sellers' option, to deliver such records to Buyer prior to such
time.

                  affect the Subject Assets, to take any of the actions set

         6.6      REAL PROPERTY AND LEASES.

         (a)      Set forth on SCHEDULE 6.6(i) is a complete and correct list of
                  all real properties owned by NPC Mexico and used in connection
                  with the Business, other than the Excluded Assets. NPC Mexico
                  has delivered or caused to be delivered true, complete and
                  correct copies of all documents evidencing the ownership by
                  NPC Mexico of the owned properties reflected in Schedule
                  6.6(i). Except for matters which would not have a Material
                  Adverse Effect, NPC Mexico has good and marketable title to
                  all its real properties, free and clear of all Liens (except
                  for Permitted Liens). No covenants, easements, rights-of-way,
                  or regulations of record impair in any material respect the
                  uses of the properties NPC Mexico for the purposes for which
                  they are now operated. The operation of the properties and
                  business of NPC Mexico in the manner in which they are now and
                  have been operated does not violate in any material respect
                  any zoning ordinances, municipal regulations, or other rules,
                  regulations, or laws. The Sellers made available to Buyer true
                  and complete copies of all surveys, appraisals and title
                  insurance policies relating to its owned real properties.

         (b)      NPC Mexico is not a party to, and neither NPC Mexico or its
                  properties are bound by, any real property lease.

         6.7 LITIGATION. Except as set forth on SCHEDULE 6.7, there is no Claim,
litigation, action, suit, proceeding, investigation or inquiry, administrative
or judicial, at law or in equity, pending or, to the Knowledge of the Sellers,
threatened against or affecting Subject Assets, the Business (or its prospects)
or any of the properties or assets of the Buyer, including any seeking to enjoin
or prevent the consummation of the transactions contemplated hereby, or
otherwise claiming the Agreement or the transactions contemplated hereby or
thereby or the consummation thereof are improper, except where such Claim,
litigation, action, suit, proceeding, investigation, or inquiry, administrative
or judicial, at law or in equity, would not have a Material Adverse Effect. To
the Knowledge of the Sellers, there is no basis upon which any such Claim could



                                       20
<PAGE>   25

reasonably be brought or initiated. The Sellers and their properties and assets
are not subject to any Order.

         6.8 COMPLIANCE WITH LAW. Except as set forth in SCHEDULE 6.8, each of
Sellers has complied in all respects, and is in compliance in all respects, with
all Laws or other requirements of any Governmental Authority, and no written
notice has been received by any of the alleging any violation, except where such
failure to comply with the Law would not have a Material Adverse Effect.

         6.9 OPTIONS TO PURCHASE. Sellers do not currently have outstanding, and
will not grant, any options, rights to purchase, Contracts, or any other right
entitling anyone to acquire any of the Subject Assets or the Business except as
otherwise expressly contemplated herein.

         6.10 TITLE TO ASSETS AND PROPERTIES, CONDITION AND SUFFICIENCY OF
ASSETS.

         (a)      NPC Mexico or NPC LLC owns good and marketable title to or
                  leasehold interests in all of the Subject Assets, free and
                  clear of all Liens, (except Permitted Liens). The Subject
                  Assets and properties owned or leased by NPC Mexico or NPC LLC
                  are in good condition, repair and working order (subject to
                  normal wear and tear consistent with the age of the assets and
                  properties), and suitable for the uses for which they are
                  intended.

         (b)      Except as set forth on SCHEDULE 6.10, the properties and the
                  Subject Assets owned by NPC Mexico or NPC LLC that are used to
                  provide administrative services to NPC Mexico are owned solely
                  by NPC Mexico or NPC LLC and the related operations have been
                  conducted solely by NPC Mexico. NPC Mexico or NPC LLC owns or
                  has valid leasehold interests in all of the properties and
                  assets which are used in the Business, or are necessary to
                  conduct the business of NPC Mexico (including, but not limited
                  to, such assets as are necessary for the operation of the
                  Business), in substantially the same manner as currently
                  conducted, except for the Excluded Assets or services used by
                  businesses generally such as the Internet, the public
                  telephone network, and public utilities. Other than the
                  Subject Assets or the Excluded Assets, neither the Sellers nor
                  any of their Affiliates owns any right, title or interest in
                  or to the properties or assets used or held for use in
                  connection with the Business. The Subject Assets, in
                  conjunction with the rights, goods and services granted, or
                  transferred by the Sellers and their Affiliates to the Buyer
                  and its Affiliates pursuant to the other Transaction
                  Documents, comprise substantially all of the assets currently
                  used or held for use by the Sellers to perform, and are
                  collectively sufficient to provide the Buyer and its
                  Affiliates with the means and capability to perform, the
                  obligations the Buyer and its Affiliates are assuming under

         6.15 ACCOUNTS RECEIVABLE. All trade and other accounts, notes and loans

due NPC Mexico, have arisen in the Ordinary Course of Business, and all such
accounts receivable (net of reserves set forth on NPC Mexico's balance sheet
included in NPC Mexico's Financial Statements or Interim Financial Statements
for such specific account or accounts in the Ordinary Course of Business) will
have been collected in full within 180 days after the earlier of the date each
such account receivable is due or the Closing Date. The Sellers have no
knowledge of facts or circumstances (other than general market conditions) that
would result in any material increase in the uncollectibility of such
receivables as a class in excess of the reserves set forth in respective
Financial Statements or Interim Financial Statements of NPC Mexico. Set forth on
SCHEDULE 6.15(i) is a true, complete and accurate aging of all of NPC Mexico's

                  used in or held for the Business encroach on any property
                  owned by others which violation or encroachment would have a
                  Material Adverse Effect at the relevant location. No
                  condemnation proceeding is pending, or to the Seller's
                  Knowledge, threatened, which would preclude or impair in any
                  material respect the use of the real property for the uses for
                  which it is currently being used.

         (b)      The real property set forth on SCHEDULE 6.16.2(b) constitutes
                  all of the real property used or occupied in connection with

                  each parcel of real property and except for matters which
                  would not have a Material Adverse Effect, NPC Mexico has good
                  and marketable title to the parcel of real property, free and
                  clear of any security interest, easement, covenant, or other
                  restriction, except for installments of special assessments
                  not yet delinquent, recorded easements, covenants, and other
                  restrictions and utility easements, building restrictions,
                  zoning restrictions, and other easement and restrictions

existing and in good standing under the laws of Mexico. Buyer is duly qualified
to do business as a foreign corporation in each jurisdiction in which its
ownership or lease of property or the nature of the business conducted by it

assets or properties of the Buyer.

         7.2 AUTHORIZATION, EXECUTION AND VALIDITY. The Buyer has all requisite
corporate power and authority to execute and deliver this Agreement and each of
the Transaction Documents to which it is a party to perform its obligations

legal, valid and binding obligation of the Buyer, enforceable against the Buyer
in accordance with its terms.

         7.3 CONSENTS. No consent, notice to or declaration, filing or
registration with, approval or authorization, or other action of any third party
or Governmental Authority is required in connection with the execution and
delivery by the Buyer of the Agreement or any Transaction Document or the
consummation of the transactions contemplated thereby, except where the failure
to obtain a consent, approval or authorization of any third party or
Governmental Authority would not have a Material Adverse Effect on the assets or
properties of the Buyer.

proceeding or investigation pending or, to the of the Knowledge of the Buyer,
threatened, that questions the validity of this Agreement or any action taken or

Knowledge of the Buyer, threatened, or any order, injunction or decree
outstanding, against the Buyer that, if adversely determined, would have a

a result of any act or omission of the Buyer, any right, interest, or valid
claim against the Sellers for any commission, fee or other compensation as a

                  ownership of the Subject Assets or activities involving the
                  Subject Assets, including any Taxes that may become

<PAGE>   38


         (a)      any breach of any representation, warranty, or other statement
                  made by or on behalf of Buyer in or pursuant to this Agreement
                  or any other Related Writing, provided, however, that
                  indemnification for a breach of the Transitional Services

         8.3 DEFENSE OF CLAIMS. If there shall be asserted in writing any Claim
against an Indemnitee, and that Indemnitee shall believe in good faith that such
Indemnitee is entitled to reimbursement or indemnity pursuant to this Section 8,
then, and in each such case, that Indemnitee shall give prompt notice of that
Claim (in each such case, the "Indemnifiable Claim") to the party (in each such
case, the "Indemnitor") to this Agreement from whom that Indemnitee so believes
itself to be so entitled, provided, that any failure or delay in the giving of
such notice shall neither (a) diminish or impair any obligation of the
Indemnitor pursuant to this Section 8 except if and to the extent that such
failure or delay shall have materially and substantially prejudiced the rights
of the Indemnitor under subsection 8.3.1 or (b) result in any liability on the
part of the Indemnitee.

         8.3.1 INDEMNITOR'S RIGHT TO ASSUME DEFENSE. With respect to each
Indemnifiable


                                       34
<PAGE>   39


Claim asserted by a third party, the Indemnitor shall have the right, at its
option and expense, to assume the defense of any Indemnifiable, provided, that,
within the period of fifteen (15) days (or within such shorter period in which
an answer or other responsive action is required by applicable rules of
procedure) after receiving notice of the Indemnifiable Claim from the
Indemnitee, the Indemnitor shall have, by notice given to the Indemnitee, (a)
acknowledged the Indemnitor's obligation to reimburse and indemnify the
Indemnitee with respect to the Indemnifiable Claim and (b) elected to defend the
Indemnifiable Claims in the name of the Indemnitee. Any such election shall be
irrevocable. Notwithstanding the foregoing, the Indemnitor shall not have the
right to assume the defense of the Indemnifiable Claim if (i) representation of
both the Indemnitee and the Indemnitor by the same legal counsel would be
prohibited by rules or regulations governing the professional conduct of such
counsel, (ii) the Indemnitee determines in good faith that there is a
significant possibility that the Indemnifiable Claim may materially and
adversely affect it or its Affiliates other than as a result of monetary
damages, or (iii) the Indemnitee determines in good faith that the Indemnitor
has insufficient financial resources to satisfy any monetary damages reasonably
likely to result from such Claim.

         8.3.2 EFFECT OF INDEMNITOR'S ELECTION TO ASSUME DEFENSE. If the
Indemnitor shall have assumed the defense of the Indemnifiable Claim in
accordance with subsection 8.3.1, then the following shall apply:

         (a)      except as provided in clause (e) of this subsection 8.3.2, the
                  Indemnitee shall have the right to participate and assist in,
                  but not control, the defense of the Indemnifiable Claim and to
                  employ its own counsel in connection therewith;

         (b)      except as provided in clause (e) of this subsection 8.3.2, the
                  Indemnitor shall not be liable to the Indemnitee for the fees
                  or expenses of the Indemnitee's counsel or other expenses
                  incurred by the Indemnitee in connection with participating in
                  the defense of the Indemnifiable Claim, except that the
                  Indemnitor shall be liable for any such fees and expenses
                  incurred prior to the time at which the Indemnitor shall have
                  elected to assume the defense of the Indemnifiable Claim;

         (c)      counsel used by the Indemnitor in connection with the defense
                  of the Indemnifiable Claim shall be subject to the prior
                  approval of the Indemnitee, which approval shall not be
                  unreasonably withheld or delayed;

         (d)      except as provided in clause (e) of this subsection 8.3.2, the
                  Indemnitor shall have no liability with respect to any
                  compromise or settlement of the Indemnifiable Claim effected
                  without its consent, which consent shall not be unreasonably
                  withheld or delayed;

         (e)      if the Indemnitor shall fail or omit to diligently prosecute
                  the defense of the Indemnifiable Claim, then, and in each such
                  case, (i) the Indemnitee shall have the right, by giving
                  notice to the Indemnitor, to take over and control the defense
                  of



                                       35
<PAGE>   40


                  the Indemnifiable Claim, (ii) the Indemnitor shall be liable
                  to the Indemnitee for any and all liabilities and any and all
                  fees, costs, expenses (including, without limitation, the fees
                  costs, and expenses of accountants, appraisers, attorneys,
                  consultants, and expert witnesses, court costs, costs of
                  defense, and costs of investigation) suffered or incurred by
                  the Indemnitee in connection with the Indemnifiable Claim and
                  (iii) the Indemnitor shall be liable for any settlement of
                  such Claim effected by the Indemnitee; and

         (f)      subject to the provisions of subsection 8.3.4, the Indemnitor
                  shall have the right to settle or otherwise dispose of the
                  Indemnifiable Claim.

         8.3.3 EFFECT OF INDEMNITOR'S ELECTION NOT TO ASSUME DEFENSE. If the
Indemnitor shall not have assumed the defense of the Indemnifiable Claim in
accordance with subsection 8.3.1, or shall not have the right to assume the
defense of the Indemnifiable Claim, then the following shall apply:

         (a)      the Indemnitee shall have the right to control the defense of
                  the Indemnifiable Claim and to employ its own counsel in
                  connection therewith;

         (b)      the Indemnitor shall have the right, at its sole cost and
                  expense, to participate in, but not control, the Defense of
                  the Indemnifiable Claim and to employ its own counsel in
                  connection therewith; and

         (c)      the Indemnitor shall be liable for any settlement of such
                  Claim effected by the Indemnitee.

         8.3.4 AUTHORITY TO SETTLE. Any compromise or settlement of the
Indemnifiable Claim shall be subject to the consent of the Indemnitee. If,
however, the Indemnitor shall give the Indemnitee notice of the Indemnitor's
desire to accept a binding and unconditional offer of settlement (the "Offered
Monetary Settlement") which (i) is limited strictly to monetary damages paid in
full by the Indemnitor, (ii) which does not include a finding or admission of
any violation of Law or any violation of the rights of any Person by the
Indemnitee, (iii) does not affect any other claim that may be made against the
Indemnitee, other than to provide for the unconditional release thereof, and
(iv) which includes, as an unconditional term thereof, the giving by the
claimant or plaintiff of a full release of the Indemnitee, in form and substance
reasonably satisfactory to the Indemnitee, from all liability in respect of such
claim and the Indemnitee does not consent to the same, then, and in each such
case, the Indemnitee may continue to pursue compromise or settlement of the
Indemnifiable Claim, free of any participation by the Indemnitor, at the sole
expense of the Indemnitee.

         8.3.5 INDEMNIFICATION LIMITATIONS. Notwithstanding any contrary
provision of this Section 8:



                                       36

         (a)      The Sellers shall have no obligation to provide
                  indemnification for Buyer Losses pursuant to this Section 8
                  unless and until the aggregate amount of all Buyer Losses for
                  which the Sellers would otherwise be obligated to provide
                  reimbursement or indemnity pursuant to this Section 8 shall
                  exceed an amount equal to Five Hundred Thousand Dollars
                  ($500,000), (the "Basket Amount") in which event the Sellers
                  shall be jointly and severally liable for all Buyer Losses for
                  which they would otherwise be liable pursuant to this Section
                  8; provided that the foregoing limitation shall not apply to
                  Buyer Losses resulting from (i) any breach of a representation
                  or warranty contained in any of Sections 6.1, 6.2, 6.7, 6.10,
                  6.13, 6.18, 6.19 or 6.21 (the "Excluded Representations"),

                  breach of any covenant or agreement of the Sellers included in
                  this Agreement or any Related Writing (collectively, the
                  "Seller Basket Exclusions"). Once Buyer Losses have exceeded
                  the Basket Amount, the Sellers shall be jointly and severally
                  obligated to pay all Buyer Losses in excess of the Basket
                  Amount. The Sellers shall be obligated to pay all Buyer Losses
                  based on the Seller Basket Exclusions without regard to the
                  individual or aggregate amounts thereof and without regard to
                  whether the aggregate of all Buyer Losses shall have exceeded,
                  in the aggregate, the Basket Amount. The maximum obligation of
                  the Sellers to provide indemnification pursuant to this
                  Section 8 shall be limited to $6,000,000 in the aggregate (the
                  "Cap"); provided, however, that the foregoing limitation shall
                  not apply to any Buyer Losses arising from (i) the Seller
                  Basket Exclusions or (ii) arising out of the actual fraud of
                  the Sellers.

         (b)      The Buyer shall have no obligation to provide indemnification
                  for Seller Losses pursuant to this Section 8 unless and until
                  the aggregate amount of all Seller Losses pursuant to this
                  Section 8 shall exceed the Basket Amount in which case Buyer
                  shall be liable for all Seller Losses for which it would
                  otherwise be liable pursuant to this Section 8; provided that
                  the foregoing limitation shall not apply to Seller Losses
                  resulting from (x) any breach of a representation or warranty
                  contained in any of Sections 7.1 or 7.2, (y) any claim for
                  indemnification pursuant to Sections 8.2(c), (e), (f), (g) or
                  (h), or (z) the breach of any covenant or agreement of the
                  Buyer included in this Agreement or any Related Writing
                  (collectively, the "Buyer Basket Exclusions"). Once Seller
                  Losses have exceeded the Basket Amount, the Buyer shall be
                  obligated to pay all Seller Losses in excess of the Basket
                  Amount. The Buyer shall be obligated to pay all Seller Losses
                  based on the Buyer Basket Exclusions without regard to the
                  individual or aggregate amounts thereof and without regard to
                  whether the aggregate of all Seller Losses shall have
                  exceeded, in the aggregate, the Basket Amount. The maximum
                  obligation of the Buyer to provide indemnification pursuant to
                  this Section 8 shall be limited to the Cap in the aggregate;
                  provided, however, that the

                  foregoing limitation shall not apply to any Seller Losses
                  arising from (i) the Buyer Basket Exclusions or (ii) the
                  actual fraud of the Buyer.

                  required to indemnify Buyer under this Section 8, each

                  Knowledge or materiality (including Material Adverse Effect)
                  qualifications that may be contained in such representation,
                  warranty and agreement.

                  reached, (i) all Shareholder Losses (as defined in the Stock
                  Purchase Agreement (the "Stock Purchase Agreement"), dated as

                  by the Sellers, and the Buyer has notified the Sellers of such
                  breach or inaccuracy, and the breach or inaccuracy has
                  continued without cure for a period of ten (10) days or such
                  shorter period prior to Closing after such notice of the
                  breach or inaccuracy; or (ii) if the Closing has not occurred,
                  within ninety (90) days from the date of this Agreement by
                  reason of the failure of any Closing condition under Section
                  10.1 (unless the failure results from the Buyer itself
                  breaching any representation, warranty or covenant contained
                  in this Agreement).

         (c)      The Sellers may terminate this Agreement by giving written
                  notice to the Buyer at any time prior to the Closing (i) in
                  the event the Buyer has breached any of its covenants
                  contained in the Agreement or there is any breach in the
                  representations or warranties made by the Buyer contained in
                  this Agreement, and the Sellers have notified the Buyer of
                  such breach or inaccuracy, and the breach or inaccuracy has
                  continued without cure for a period of ten (10) calendar days
                  or such shorter



                                       44

                  period prior to Closing after such notice of breach or
                  inaccuracy; or (ii) if the Closing has not occurred, within
                  ninety (90) calendar days from the date of the Agreement by
                  reason of the failure of any Closing condition under Section
                  10.2 (unless the failure results primarily from the Sellers
                  breaching any representation warranty or covenant contained in
                  the Agreement).

         12.2 EFFECT OF TERMINATION. If any party terminates this Agreement
pursuant to Section 12.1, all rights and obligations of the parties hereunder
shall terminate without any liability of any party to any other party; provided,
however, that (a) if this Agreement is terminated by a party due to the breach
by the other party of any covenant or agreement contained herein, or due to any
breach or misrepresentation in any of such other party's representations or
warranties contained herein, or due the failure of such other party to fulfill
its obligations in connection with the satisfaction of any condition to Closing,
then the terminating party shall remain entitled to pursue all available legal
rights and remedies pursuant to this Agreement or otherwise notwithstanding such
termination; and (b) the provisions of Section 13 of the Agreement will survive
termination and remain in full force and effect thereafter.

written notice to the other parties to the Agreement.

         13.3 CONFIDENTIALITY. Except as required by the laws of the United
States, including regulations of the Securities and Exchange Commission, the
Sellers and Buyer will hold and will cause their consultants and advisers to
hold in strict confidence, unless compelled to disclose by judicial or
administrative process or, in the opinion of their counsel, by other
requirements of law, all documents and information concerning the other party
furnished to them by the other party or their representatives in connection with
the Agreement or the transactions contemplated by this Agreement (except to the
extent that such information can be shown to have been (a) in the public domain
through no fault of the other party, (b) previously known by the other party on
a non-confidential basis from a source not known by such party to be under any
confidentiality restriction, (c) later lawfully acquired by the other party from
a source not known by such party to be under any confidentiality restriction, or
(d) independently developed by the other party without the use of information
subject to this confidentiality restriction) and neither party will release or
disclose such information to any other person, except its auditors, attorneys,
financial advisers, bankers and other consultants and advisers in connection
with this Agreement. If the transactions contemplated by this Agreement are not
consummated, such confidence will be maintained except to the extent that such
information comes into the public domain through no fault of either party and
such information shall not be used to the detriment of, or in relation to any
investment in, the other party and all such documents (including copies thereof)
shall be returned to the other party immediately on the request of either party.
Both parties shall be deemed to have satisfied their obligation to hold
confidential information concerning or supplied


                                       46
<PAGE>   51


by the other party if it exercises the same care as it takes to preserve
confidentiality for their own similar information. In addition, neither the
Sellers or any officer, director, employee, representative or shareholder of the
foregoing, from the date hereof through the Closing Date, shall make, solicit or
initiate proposals or offers for any business combination or restructuring
involving the Business, or the purchase, sale, lease or other disposition of any
of the Subject Assets, however structured or to be effected, other than
transactions in the Ordinary Course of Business involving assets which, in the
aggregate, are not material. The Sellers further agree that neither they nor
their officers, directors, agents or representatives acting on its behalf during
such period will negotiate with any party other than the Buyer or its
Affiliates, or provide information in furtherance of any such proposal or offer.

         13.4 ENTIRE AGREEMENT. The Agreement (including the exhibits and
Schedules hereto, and the documents and instruments executed and delivered in
connection herewith, or referred to herein) constitutes the entire agreement
among the parties with respect to the subject matter hereof and supersedes any
prior and contemporaneous understandings, agreements, or representations,
whether written or oral, by or among the parties, or any of them with respect to
the subject matter hereof that are not fully expressed in this Agreement and the
documents and instruments executed and delivered in connection herewith.

         13.5 PARTIES IN INTEREST; SUCCESSORS AND ASSIGNS. This Agreement shall
be binding upon and inure solely to the benefit of the parties hereto and their
respective successors, legal representatives and permitted assigns. Neither this
Agreement nor any rights or obligations hereunder may be assigned without the
written consent of the other parties except that Buyer may assign any or all of
its rights, interest and obligations hereunder to any of its Affiliates and/or
its financing sources (provided that no such assignment shall discharge Buyer
from any such obligations). Nothing in this Agreement, express or implied, is
intended to or shall confer upon any Person, other than the parties hereto and
their respective successors, legal representatives and permitted assigns, any
rights, benefits or remedies of any nature whatsoever under or by reason of this
Agreement, and no Person shall be deemed a third party beneficiary under or by
reason of this Agreement.

         13.6 SPECIFIC PERFORMANCE. Each of the parties hereto acknowledges and
agrees that (i) the provisions of this Agreement are reasonable and necessary to
protect the proper and legitimate interests of the other parties hereto, and
(ii) the other parties hereto would be irreparably damaged in the event any of
the provisions of this Agreement were not performed in accordance with their
specific terms or were otherwise breached. It is accordingly agreed that the
parties hereto shall be entitled to preliminary and permanent injunctive relief
to prevent breaches of the provisions of this Agreement by other parties hereto
without the necessity of proving actual damages or of posting any bond, and to
enforce specifically the terms and provisions hereof and thereof, which rights
shall be cumulative and in addition to any other remedy to which the parties
hereto may be entitled hereunder or at law or equity.

         13.7 SEVERABILITY. Any term or provision of this Agreement or the
application of any such provision to any Person or circumstance shall be
declared judicially to be invalid, unenforceable or void, such decision shall
not have the effect of invalidating or voiding the remainder of this Agreement,
it being the intent and agreement of the parties that this Agreement shall be
deemed amended by modifying such provision to the extent necessary to render it
valid, legal and enforceable while preserving its intent or, if such
modification is not possible, by substituting therefor another provision that is
valid, legal and enforceable and that achieves the same objective.

         13.8 CONSTRUCTION. The parties have participated jointly in the
negotiation and drafting of the Agreement. In the event an ambiguity or question
of intent or interpretation arises, the Agreement shall be construed as if
drafted jointly by the parties and no presumption or burden of proof shall arise
favoring or disfavoring any party by virtue of the authorship of any of the
provisions of the Agreement. Any reference to any federal, state, local or
foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context requires otherwise. The
article and section headings and the table of contents contained in this
Agreement are for convenience of reference only and shall in no way define,
limit, extend or describe the scope or intent of any provisions of this
Agreement. Whenever the context may require, any pronoun used in this Agreement
shall include the corresponding masculine, feminine or neuter forms, and the
singular form of nouns, pronouns and verbs shall include the plural and vice
versa. In addition, as used in this Agreement, unless otherwise provided to the
contrary, (a) all references to days, months or years shall be deemed references
to calendar days, months or years and (b) any reference to a "Section,"
"Article," or "Schedule" shall be deemed to refer to a section or article of
this Agreement or an exhibit or schedule attached to this Agreement. The words
"hereof", "herein", and "hereunder" and words of similar import referring to
this Agreement refer to this Agreement as a whole and not to any particular
provision of this Agreement. Unless otherwise specifically provided for herein,
the term "or" shall not be deemed to be exclusive.

         13.9 DISPUTES. If the parties are unable to resolve any disagreement,
dispute, controversy or claim that may arise out of the transactions
contemplated by this Agreement, including, without limitation, the failure to
agree upon any item requiring a mutual agreement of the parties hereunder, they
shall resolve the disagreement or dispute as follows:

         (a)      Sellers may refer the matter to the Chief Financial Officer of
                  Parent or any other executive officer as the Chief Financial
                  Officer so designates and Buyer may refer the matter to the
                  Chief Financial Officer or to any other Executive Officer as
                  the Chief Financial Officer so designates of Buyer (the
                  "Officers") by giving the other party written notice (a
                  "Notice"). Within 30 days after delivery of a Notice, the
                  Officers of both parties shall meet at a mutually acceptable
                  time and place to exchange relevant information and to attempt
                  to resolve the dispute.



                                       48
<PAGE>   53


         (b)      If the matter has not been resolved within 60 days after
                  delivery of such Notice, or if the Officers fail to meet
                  within 30 days after delivery of such Notice, Parent or Buyer
                  may initiate mediation. All negotiations conducted by the
                  Officers pursuant to this clause are confidential and shall be
                  treated as compromise and settlement negotiations for purposes
                  of the Federal Rules of Evidence and State Rules of Evidence.

         (c)      In the event a dispute exists between the parties and the
                  respective Officers are unable to resolve the dispute, the
                  parties agree to participate in a non-binding mediation
                  procedure as follows:

                  (i)      A mediator will be selected by having counsel for
                           each party agree on a person to act as mediator. The
                           parties' counsel as well as the Officers of each
                           party and not more than two other participants from
                           each party will appear before the mediator at a time
                           and place determined by the mediator, but not more
                           than 60 days after delivery of a Notice. The fees of
                           the mediator and other costs of mediation will be
                           shared equally by the parties.

                  (ii)     Each party's counsel will have 45 minutes to present
                           a review of the issue and argument before the
                           mediator. After each counsel's presentation, the
                           other counsel may present specific counter-arguments
                           not to exceed 10 minutes. The 45-minute and 10-minute
                           periods will be exclusive of the time required to
                           answer questions from the mediator or attendees.

                  (iii)    After both presentations, the Officers may ask
                           questions of the other side. At the conclusion of
                           both presentations and the question periods, the
                           Officers and their counsels will meet together to
                           attempt to resolve the dispute. The length of the
                           meeting will be as agreed between the parties. Either
                           party may abandon the procedure at the end of the
                           presentations and question periods if they feel it is
                           not productive to go further. This mediation
                           procedure is not binding on either party.

                  (iv)     The duties of the mediator are to be sure that the
                           above set-out time periods are adhered to and to ask
                           questions so as to clarify the issues and
                           understanding of the parties. The mediator may also
                           offer possible resolutions of the issue but has no
                           duty to do so.

         (d)      After applying the mediation procedures set forth above, or if
                  either of Parent or Buyer refuses to take part in the
                  mediation process, either Parent or Buyer may submit the
                  matter to arbitration in accordance with Section 13.9(f).

         (e)      The provisions of this Section 13.9 shall not be construed to
                  prevent either Parent or Buyer from instituting proceedings at
                  law or in equity earlier (i) to avoid the


                                       49
<PAGE>   54


                  expiration of any applicable limitations period; or (ii) where
                  a party makes a good faith determination that a temporary
                  restraining order or other immediate injunctive relief is the
                  only adequate remedy.

         (f)      Subject to the mediation procedures set forth above, any
                  controversy or claim arising out of, or relating to, the
                  Agreement, or the making, performance, or interpretation of
                  it, shall be settled by arbitration in Chicago, Illinois, or
                  such other location agreed to by the parties, in accordance
                  with the Commercial Rules of Arbitration of the American
                  Arbitration Association ("AAA") then existing, pursuant to a
                  written award with the findings of fact and conclusions of law
                  (which award shall be consistent with the Agreement and
                  applicable Governmental Authority) and judgment on the
                  arbitration award may be entered in any court having
                  jurisdiction over the subject matter of the controversy;
                  provided, that punitive damages may not be awarded in such
                  arbitration. The arbitrators shall have the right to employ
                  experts, the cost of which will be equally shared by the Buyer
                  and the Sellers, to assist them in any arbitration proceeding
                  under this Section 13.9(f) and shall have the right to render
                  equitable, as well as other, awards and relief. Before
                  submitting a list of potential arbitrators to the parties for
                  their consideration, the AAA shall consult with each party to
                  discuss the applicable qualifications of the proposed
                  arbitrators. Upon written request by the Company or the Buyer
                  as to any particular controversy or claim under the Agreement
                  with a copy of any such request also being sent to the other
                  party or parties in accordance with the notice provisions of
                  the Agreement, the AAA shall select a panel of at least three
                  arbitrators, but if no such request is made by the time the
                  parties comment on any proposed list of arbitrators, the AAA
                  may select a single arbitrator unless the AAA determines that
                  a greater number of arbitrators is appropriate. Each
                  arbitrator shall be a currently licensed lawyer in the United
                  States of America with at least twenty years experience in
                  merger and acquisition practice in the United States.

         (g)      The dispute resolution procedures set forth above shall
                  survive the termination of this Agreement.

         13.10 GOVERNING LAW. The Agreement shall be governed by and construed
and interpreted in accordance with the internal, substantive laws of the State
of Delaware, United States of America. The Sellers and Buyer hereby consent and
submit to the jurisdiction and venue of the courts of competent jurisdiction
location in the State of Delaware for the purposes of any legal action or
proceeding arising out of the Agreement.

         13.11 COUNTERPARTS. The Agreement may be executed concurrently in two
or more counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument, binding on all the
parties, notwithstanding that all the parties are not signatories to the
original or the same counterpart.

cooperate in the development and distribution of any and all news releases,
other announcements, or public disclosure of matters related to this Agreement
