     hereof and Sections 2.7 and 7.3(g) of the PCM Merger Agreement and shall be

     this Section 2.8.

          (b) Determination of NSI Merger Consideration. The final determination
     of the NSI Merger Consideration shall be made in accordance with Section
     2.8(b) and, if applicable, Section 2.9, of the PCM Merger Agreement.

          (c) Adjustments. If it is necessary to adjust the payment made to the
     Stockholder or Pironti on the Effective Date pursuant to Sections 2.8 (b)
     or 7.3(g) of the PCM Merger Agreement or Section 7.3(f) hereof any such
     required adjustment (the "Adjustment") shall be made not later than five
     (5) days following the final determination thereof, as the same may be
     extended pursuant to Section 2.9 of the PCM Merger Agreement (such day, the
     "Adjustment Date"), as follows, but without duplication to the adjustments
     set forth in the PCM Merger Agreement:

               (i) If the sum of the NSI Merger Consideration and the PCM Merger
          Consideration, as set forth in the PCM Merger Agreement (together, the
          "Aggregate Merger Consideration"), is greater than the sum of the
          Estimated NSI Merger Consideration and the Estimated PCM Merger
          Consideration, as set forth in the PCM Merger Agreement (together, the
          "Aggregate Estimated Merger Consideration"), (A) the Purchase Note
          shall be amended and restated by increasing the principal amount
          thereof by forty six percent (46%) of such Adjustment, (B) the
          Negotiable Purchase Note shall be amended and restated by increasing
          the principal amount thereof by fifty four percent (54%) of such
          Adjustment and (C) PCM Surviving Corporation shall make a cash payment
          to the Stockholder in the amount of the extent to which payments on
          such Notes by PCM Surviving Corporation to the Stockholder between the
          Effective Date and the Adjustment Date were lower than they should
          have been, retroactive to the Effective Date.

               (ii) If the Aggregate Merger Consideration is less than the
          Aggregate Estimated Merger Consideration, (A) the Purchase Note shall
          be amended and restated by reducing the principal amount thereof by
          forty six percent (46%) of such Adjustment, (B) the Negotiable
          Purchase Note shall be amended and restated by reducing the principal
          amount thereof by fifty four percent (54%) of


                                       10
<PAGE>

          such Adjustment and (C) the Stockholder shall make a cash payment to
          PCM Surviving Corporation in the amount of the extent to which
          payments by PCM Surviving Corporation to the Stockholder between the
          Effective Date and the Adjustment Date were higher than they should
          have been, retroactive to the Effective Date. In the event that the
          net amount of any downward adjustment exceeds the outstanding
          principal balance of the Purchase Note or the Negotiable Purchase
          Note, as the case may, as of the Adjustment Date, then such excess
          shall be applied as a reduction to the other Note, in the fashion
          described above, and the Stockholder shall, on the Adjustment Date,
          surrender the applicable Note to PCM Surviving Corporation for
          cancellation. In the event such downward adjustment also exceeds the
          principal balance of such other Note, the Stockholder shall, on the
          Adjustment Date, surrender such other Note to PCM Surviving
          Corporation for cancellation and shall pay PCM Surviving Corporation
          an amount equal to the amount by which the net amount of such downward
          adjustment exceeds such outstanding principal balance. In addition,
          the Stockholder shall make a cash payment to PCM Surviving Corporation
          in the amount of the extent to which payments on such Notes by PCM
          Surviving Corporation to the Stockholder between the Effective Date
          and the Adjustment Date were higher than they should have been,
          retroactive to the Effective Date, together with interest on such
          amount computed at an annual rate of 7% per annum to the date of such
          payment.

               (iii) If the aggregate amount of the payment made to Pironti and
          Stockholder on the Effective Date pursuant to Section 7.3(f) hereof
          and Section 7.3(g) of the PCM Merger Agreement is greater or lesser
          than the amount of such payment as determined in accordance with
          Section 2.8(b), the Negotiable Purchase Note shall be amended, or
          further amended, and restated in the manner described in paragraph (i)
          or (ii) above, as applicable (and if applicable a further cash payment
          of principal and interest shall be made to give effect to such
          adjustment).

          not paid pursuant to subsection (ii) above, and (r) the excess of (m)
          the Joint Ventures' Income for calendar year 2003 over (n) $1,000,000
          (the amounts set forth in subsection (ii)(B)(y) above and this
          subsection (iii)(B)(r), to the extent not paid at any time, shall be
          referred to as the "Carried Forward JV Amounts").

               (i) The Annual JV Entitlement shall be paid in quarterly
          payments, subject to an annual reconciliation. Within forty five (45)

          quarter. Each such payment shall be accompanied by a statement setting
          forth in reasonable detail the basis for the calculation of such
          Quarterly Payment.

               (ii) Within 60 days following the end of each calendar year, NSI
          Surviving Corporation shall deliver to the Stockholder a statement of
          the Annual JV Entitlement for such calendar year, together with (x) a
          statement setting forth in reasonable detail the Joint Ventures'
          Income for such calendar year (the "JV Income Statement"), to be
          derived from the financial statements of the Joint Ventures and NSI
          Surviving Corporation, and (y) payment equal to the Annual JV
          Entitlement for such calendar year reduced by the aggregate payments
          made during the first three calendar quarters; provided that if the
          Annual JV Entitlement for such calendar year is less than the amount
          of the aggregate payments made during the first three calendar
          quarters, the Stockholder shall make payment of such shortfall to NSI
          Surviving Corporation. NSI Surviving Corporation shall permit the
          Stockholder and his designees reasonable access to its auditors and to
          the books and records of the Joint Ventures and NSI Surviving
          Corporation to the


                                       12
<PAGE>

          extent utilized in the preparation of the JV Income Statement and to
          all working papers relating to the JV Income Statement, and shall
          direct such accountants to respond to any inquiries of the Stockholder
          or such designees relating thereto. In the event the Stockholder has
          any dispute with respect to the JV Income Statement, he shall follow
          the procedures set forth in subparagraph (iii) below.

               (iii) If the Stockholder disagrees with any matter set forth in
          the JV Income Statement, he shall provide NSI Surviving Corporation
          with notice of such disagreement setting forth in reasonable detail
          the nature and basis of such disagreement and his view as to the
          correct amount of any Annual Entitlement (each such notice, a "Dispute
          Notice"). The Stockholder shall provide such Dispute Notice, if
          applicable, within twenty (20) days after delivery of the JV Income
          Statement; provided, that the foregoing twenty (20) day notice may be
          extended as the Stockholder may reasonably request if he or his
          designees have been denied the access described in subsection (ii)
          above. If the Stockholder does not deliver a Dispute Notice within
          such twenty (20) day (or extended) period, the Stockholder shall be
          deemed to have agreed with the matters set forth in the JV Income
          Statement. If the Stockholder timely provides a Dispute Notice to the
          Parent, then: (a) the representatives of NSI Surviving Corporation and
          the Stockholder ("Representatives") shall meet promptly and attempt in
          good faith to resolve any differences. If the Representatives cannot
          mutually resolve such disagreement within ten (10) days after the
          delivery of the Dispute Notice, such dispute promptly shall be
          submitted for resolution to a recognizable and reputable certified
          public accounting firm that is mutually acceptable to the
          Representatives. Such accounting firm promptly shall resolve the
          matters that are in disagreement among the Parties as set forth in the
          Dispute Notice in accordance with the terms of this Agreement, and
          promptly shall deliver its determination in writing to NSI Surviving
          Corporation and the Stockholder (the "Accountants' Determination").
          The fees and expenses of such accounting firm in respect of each
          dispute shall be shared pro rata as between the Parent and the
          Stockholder on the basis of the percentage difference between such
          accounting firm's conclusion and the amount set forth in the JV Income
          Statement and the amount set forth in the Dispute Notice. The
          determination of such accounting firm shall be final and binding upon
          all of the Parties to this Agreement.

               (iv) In the event of a dispute respecting the amount of the
          Annual JV Entitlement pursuant to subsection (iii) above, if the JV
          Income Statement, as ultimately determined, is different than the
          statement issued by NSI Surviving Corporation pursuant to subsection

               (i) In the event Parent fails to make any payment pursuant to

          Venture to use an Affiliate of the Parent or the NSI Surviving
          Corporation as a membership club for any Joint Venture Project, but
          only if the terms thereof are no less favorable than those that would
          be available to such Joint Venture from unrelated third parties.

     2.10 Tax Treatment. It is the intention of each Party that the NSI Merger
shall qualify as a tax-free reorganization as described in Recital F.

3.   Representations and Warranties of NSI and the Stockholder. NSI and the
Stockholder hereby, jointly and severally, represent and warrant to Parent and
NSI Merger Sub as follows:

     3.1 Organization and Qualification; Absence of Subsidiaries. NSI is a
corporation duly organized, validly existing and in good standing under the laws
of the State of New York and has the requisite corporate power and authority
necessary to own, lease and operate the properties it purports to own, operate
or lease and to carry on the Business as it is now being conducted, except where
the failure to be so organized, existing and in good standing or to have such
power or authority would not reasonably be expected to have a Material Adverse
Effect. NSI is duly qualified or licensed as a foreign corporation to do
business, and is in good standing, in each jurisdiction where the character of
its properties owned, leased or operated by it or the nature of its activities
makes such qualification or licensing necessary. Except for its interest in the
Joint Ventures, NSI does not directly or indirectly own any equity or similar
interest in, or any interest convertible into or exchangeable or exercisable
for, any equity or similar interest in, any corporation, partnership, joint
venture or other business association or entity.

     3.2 Articles of Incorporation and By-laws. NSI has heretofore made
available to Parent a complete and correct copy of its Articles of Incorporation
and By-laws as amended to date (the "NSI Charter Documents"). Such NSI Charter
Documents are in full force and effect. NSI is not in violation of any of the
provisions of its Articles of Incorporation or By-laws or equivalent
organizational documents, except for violations of the documents which do not
and are not reasonably likely to materially interfere with the operations of
such entity.

     3.3 Capitalization. The authorized capital stock of NSI consists solely of
20,000 shares of NSI Common Stock, 100 shares of which are issued and
outstanding, all of which are validly issued, fully paid, and nonassessable.
Except as set forth on Section 3.3 of the NSI Disclosure Schedule, there are no
options, warrants, or other rights, agreements, arrangements or commitments of
any character binding on NSI relating to the issued or unissued capital stock of
NSI or obligating NSI to issue or sell any shares of capital stock of, or other
equity interests in, NSI. There are no obligations, contingent or otherwise, of
NSI to repurchase, redeem, or otherwise acquire any shares of NSI Common Stock.

     3.4 Ownership of NSI Common Stock; Voting. Except as set forth in Section
3.4 of the NSI Disclosure Schedule, the Stockholder is the sole holder of record
of and has good and valid title to all issued and outstanding shares of NSI
Common Stock, free and clear of all Liens. Except as set forth in Section 3.4 of
the NSI Disclosure Schedule, there are no agreements or understandings in effect
with the Stockholder or with any other person with respect to the voting,


                                       15
<PAGE>

transfer, disposition or registration under the Securities Act of 1933, as
amended, of any shares of NSI Common Stock.

     3.5 Authorization; Binding Agreement. NSI has all necessary corporate power
and authority, and the Stockholder has the legal capacity, to execute and
deliver this Agreement and to perform its and his obligations hereunder and to
consummate the transactions contemplated hereby. The execution and delivery of
this Agreement by NSI and the consummation by NSI of the transactions
contemplated hereby (including the NSI Merger) have been duly and validly
authorized by all necessary corporate action, including stockholder approval,
and no other corporate proceedings on the part of NSI are necessary to authorize
this Agreement or to consummate the transactions so contemplated (other than the
filing of the appropriate documents with respect to the NSI Merger in accordance
with the BCL and the Delaware General Corporation Law (the "DGCL"). As of the
date hereof, the Board of Directors of NSI has determined that it is advisable
and in the best interest of the Stockholder for NSI to enter into this Agreement
and to consummate the NSI Merger upon the terms and subject to the conditions of
this Agreement. This Agreement has been duly and validly executed and delivered
by NSI and the Stockholder and, assuming the due authorization, execution and
delivery hereof by Parent and NSI Merger Sub, constitutes a legal, valid and
binding obligation of NSI and the Stockholder, enforceable against NSI and the
Stockholder in accordance with its terms.

     3.6 No Conflict; Required Filings and Consents.

          (a) Except as set forth in Section 3.6(a) of the NSI Disclosure
     Schedule, the execution and delivery of this Agreement by NSI does not, and
     the performance of this Agreement by NSI will not, (i) conflict with or
     violate the Articles of Incorporation or By-laws of NSI, (ii) conflict with
     or violate any law, rule, regulation, order, judgment or decree applicable
     to NSI or by which its or properties are bound or affected, or (iii) result
     in any breach of or constitute a default (or an event that with notice or
     lapse of time or both would become a default), or impair NSI's rights or
     alter the rights or obligations of any third party under, or give to others
     any rights of termination, amendment, acceleration or cancellation of, or
     result in the creation of a lien or encumbrance on (including a right to
     purchase) any of the properties or assets of NSI pursuant to, any note,
     bond, mortgage, indenture, contract, agreement, lease, license, permit,
     franchise or other instrument or obligation to which NSI is a party or by
     which NSI or its properties is bound or affected, except, in the case of
     clauses (ii) or (iii), for any such conflicts, violations, breaches,
     defaults or other occurrences that would not reasonably be expected,
     individually or in the aggregate, to have a Material Adverse Effect.

          (b) Except as set forth in Section 3.6(b) of the NSI Disclosure
     Schedule, the execution and delivery of this Agreement by NSI does not, and
     the performance of this Agreement by NSI will not, require any consent,
     approval, authorization or permit of, or filing with or notification to,
     any governmental or regulatory authority, domestic or foreign (each, a
     "Governmental Authority"), except (i) for applicable requirements, if any,
     of the Exchange Act and state securities laws ("Blue Sky Laws") and the
     filing and recordation of appropriate merger or other documents as required
     by the BCL, (ii) where the failure to obtain such consents, approvals,
     authorizations or permits, or to make such filings or notifications, would
     not prevent or materially delay consummation of the NSI


                                       16
<PAGE>

     Merger, or otherwise prevent or materially delay NSI from performing its
     material obligations under this Agreement, or would not otherwise
     reasonably be expected, individually or in the aggregate, to have a
     Material Adverse Effect, or (iii) as to which any necessary consents,
     approvals, authorizations, permits, filings or notifications have
     heretofore been obtained or filed, as the case may be, by NSI; provided,
     however, that no representation or warranty is made under this Section
     3.6(b) as to the requirement to make any filing pursuant to the pre-merger
     notification requirements of the Hart-Scott-Rodino Antitrust Improvements
     Act, as amended, and the rules and regulations thereunder (the "HSR Act").

          (c) The "acquired person" (as defined in the HSR Act) that includes
     NSI with respect to the transactions contemplated under the Merger
     Agreement does not have total assets or annual net sales of $100,000,000 as
     determined in accordance with the HSR Act.

     3.7 Compliance; Permits.

          (a) Except as disclosed in Section 3.7(a) of the NSI Disclosure
     Schedule, NSI is not in conflict with, or in default or violation of, (i)
     any law, rule, regulation, order, judgment or decree applicable to NSI or
     by which its properties is bound or affected or (ii) any note, bond,
     mortgage, indenture, contract, agreement, lease, license, permit, franchise
     or other instrument or obligation to which NSI is a party or by which NSI
     or its respective properties is bound or affected.

          (b) Except as disclosed in Section 3.7(b) of the NSI Disclosure
     Schedule, NSI holds all permits, licenses, easements, variances,
     exemptions, consents, certificates, orders and approvals from governmental
     authorities which are material to the operation of the Business as it is
     now being conducted (collectively, the "NSI Permits"). NSI is in compliance
     with the terms of NSI Permits.

     3.8 Financial Statements. NSI has heretofore delivered to Parent complete
and correct copies of the following financial statements (collectively, the
"Financial Statements"), all of which have been prepared from the books and
records of NSI and, to NSI's knowledge, the Financial Statements fairly present
in all material respects the financial condition of NSI as at their respective

an audited balance sheet at December 31, 1999 and audited statements of income,
cash flow and shareholders' equity of NSI for the fiscal year then ended; (y) an
audited balance sheet at December 31, 2000 (the "Last Audited Balance Sheet")
and audited statements of income, cash flow and shareholders' equity of NSI for
the fiscal year then ended; and (z) an unaudited balance sheet (the "Interim
Balance Sheet") of NSI as at September 30, 2001 (the "Interim Balance Sheet
Date") and statements of income and cash flow for the nine months then ended. To
the knowledge of NSI and the Stockholder, and except as disclosed in Section 3.8
of the NSI Disclosure Schedule:

          (a) No such statements of income contain any items of special or
     nonrecurring revenue or income or any revenue or income generated other

     course of NSI's business, NSI does not have any liabilities, debts or
     obligations (whether absolute, accrued, contingent or otherwise) of the
     type required to be included on a balance sheet prepared in accordance with
     GAAP. Section 3.8(b) of the NSI Disclosure Schedule lists, for each item
     identified, the lender or other obligee and, in the case of guarantees and
     other contingent liabilities, the beneficiary of such obligations;

          (c) All receivables of NSI (including accounts receivable, loans
     receivable and advances that are reflected in the Interim Balance Sheet,

     the Effective Time), have arisen or will have arisen only from bona fide
     transactions in the ordinary course of business and shall be fully
     collectible at the aggregate recorded amounts thereof (except to the extent
     of appropriate reserves established in accordance with GAAP and the
     Accounting Protocol) and are not and will not be subject to defense,
     counterclaim, or offset; and

          (d) All items of supplies and other consumables reflected on the
     Interim Balance Sheet, and all such items of supplies and other consumables
     that are acquired thereafter and prior to the Effective Time, are or will
     be useable in the ordinary course of business. NSI has and will through the
     Effective Time maintain a sufficient but not an excessive quantity of each
     type of such supplies and other consumables in order to meet the normal
     requirements of its business and operations.

          practices.

               (vii) Neither NSI nor any Affiliate has received notice of the
          intent of any federal, state, local or foreign agency responsible for
          the enforcement of labor or employment laws to conduct an
          investigation of NSI, and, to the knowledge of NSI, no such

     "employee pension benefit plans" (as defined in Section 3(2) of ERISA), all
     medical, disability, life insurance and other "employee welfare benefit

     benefit plans, policies, programs, agreements or arrangements (whether
     written or otherwise), including those which contain change of control
     provisions or pending change of control provisions, in any case that (i)
     are maintained or contributed to (or to which there was an obligation to
     contribute) by NSI, or (ii) were formerly maintained or contributed to (or
     to which there was an obligation to contribute), by either NSI or any
     subsidiary, as well each plan with respect to which NSI, a subsidiary or
     any other entity (whether or not incorporated), which is a member of a
     controlled group including NSI or which is under common control with NSI
     within the meaning of Section 414(b), (c) or (m) of the Code (a "NSI ERISA
     Affiliate"), if NSI or any NSI ERISA Affiliate has or could have any
     liability with respect to any such plan, whether direct or indirect or
     actual or contingent (including, without limitation, any liability arising
     out of an indemnification, guarantee, hold harmless or similar agreement)
     ("NSI Employee Plans").

          (b) NSI has made available to Parent, prior to the date of this
     Agreement, copies of (i) each such written NSI Employee Plan (or a written
     description of any NSI Employee Plan which is not written) and all related
     trust agreements, insurance and other contracts (including policies),
     summary plan descriptions, summaries of material modifications and
     communications distributed to plan participants, (ii) the three most recent
     annual reports on Form 5500 series, with accompanying schedules and
     attachments, filed with respect to each NSI Employee Plan required to make
     such a filing, (iii) the latest reports which have been filed with the
     Department of Labor with respect to each NSI Employee Plan required to make
     such filing and (iv) the most recent favorable determination letters issued

     qualified under Section 401(a) of the Code (and, if an application for such
     determination is pending, a copy of the application for such
     determination).

          (c) None of the NSI Employee Plans promises or provides retiree
     medical or other retiree welfare benefits to any person (except as
     necessary to comply with Section 4980B of the Code ("COBRA")).

          (d) (i) No party in interest or disqualified person (as defined in
     Section 3(14) of ERISA and Section 4975 of the Code) has at any time
     engaged in a transaction with respect to any NSI Employee Plan which could
     subject NSI or any NSI ERISA Affiliate,


                                       25
<PAGE>

     directly or indirectly, to a tax, penalty, or other liability for
     prohibited transactions under ERISA or Section 4975 of the Code; (ii) no
     fiduciary (as defined in Section 3(21) of ERISA) with respect to any NSI
     Employee Plan, or for whose conduct NSI could have any liability (by reason
     of indemnities or otherwise), has breached any of the responsibilities or
     obligations imposed upon the fiduciary under Title I of ERISA; and (iii) no
     fiduciary of any NSI Employee Plan has breached any of the responsibilities
     or obligations imposed upon fiduciaries under Title I of ERISA, which
     breach would reasonably be expected to result in any liability to NSI or
     any NSI ERISA Affiliate.

          (e) (i) All NSI Employee Plans have been established and maintained
     substantially in accordance with their terms and have operated in
     compliance with the requirements of applicable law (including but not
     limited to the applicable notification and other requirements of COBRA, the
     Health Insurance Portability and Accountability Act of 1996, the Newborns'
     and Mothers' Health Protection Act of 1996, the Mental Health Parity Act of
     1996, and the Women's Health and Cancer Rights Act of 1998), and may by
     their terms be amended and/or terminated at any time to the greatest extent
     permitted by applicable law, and NSI has performed all obligations required
     to be performed by it under, is not in default under or violation of, and
     has no knowledge of any default or violation by any other party to, any of
     the NSI Employee Plans; (ii) each NSI Employee Plan which is intended to be
     qualified under Section 401(a) of the Code is the subject of a favorable
     determination letter from the IRS, and, to NSI's knowledge, nothing has
     occurred which may reasonably be expected to impair such determination; and
     (iii) all contributions required to be made with respect to any NSI
     Employee Plan have been made on or before their due dates (including any
     extensions thereof) and all such amounts accrued but not yet paid have been
     properly recorded in the books of NSI and reflected in the financial books
     of NSI.

          (f) (i) Other than routine claims for benefits made in the ordinary
     course of the operation of the NSI Employee Plans, there are no pending,
     nor to NSI's knowledge any threatened, claims, investigations or causes of
     action with respect to any NSI Employee Plan, whether made by a participant
     or beneficiary of such a plan, a governmental agency or otherwise, against
     NSI, any NSI director, officer or employee, any NSI Employee Plan or any
     fiduciary of a NSI Employee Plan; and (ii) there are no communications to
     any employee, former employee or any other person who may be entitled to
     benefits under any NSI Employee Plan that are inconsistent with any
     provision of any NSI Employee Plan.

          (g) No NSI Employee Plan is or ever was subject to Section 302 of
     ERISA, Section 412 of the Code or Title IV of ERISA and no NSI Employee
     Plan is or ever was a "multiemployer plan" as defined in Section 3(37) of
     ERISA or a "multiple employer plan" as defined in Section 3(40) of ERISA.
     With respect to any NSI Employee Plan, no "reportable event" within the
     meaning of Section 4043 of ERISA (excluding any such event for which the 30
     day notice requirement has been waived under the regulations to Section
     4043 of ERISA) has occurred nor would the consummation of the transactions
     contemplated hereby (including the execution of this Agreement) constitute
     a reportable event for which the 30-day requirement has not been waived.
     Neither NSI nor any NSI ERISA Affiliate has incurred or reasonably expects
     to incur and no facts or conditions


                                       26
<PAGE>

     exist as a result of which NSI or a NSI ERISA Affiliate could incur any
     liability under Title IV of ERISA including, without limitation, with
     respect to an event described in Section 4201, 4204 or 4212 of ERISA (or
     under any agreement, instrument, statute, rule of law or regulation
     pursuant to or under which NSI or a NSI ERISA Affiliate has agreed or is
     required to indemnify any person against such liability). The Pension
     Benefit Guaranty Corporation has not instituted proceedings to terminate
     any such NSI Employee Plan, and no such plan has incurred any "accumulated
     funding deficiency" as defined in Section 302 of ERISA and Section 412 of
     the Code), whether or not waived, and no extensions of any amortization
     period within the meaning of Section 412 of the Code or Section 302 of
     ERISA been applied for with respect thereto. With respect to each
     multiemployer plan, Section 3.17(g) of the Disclosure Schedule specifies
     the "withdrawal liability" within the meaning of Section 4201 of ERISA that
     NSI or a NSI ERISA Affiliate would have incurred had NSI or such NSI ERISA
     Affiliate effected a "complete withdrawal" (within the meaning of Section
     4203 of ERISA) as of a recent date specified in Section 3.17(g) of the
     Disclosure Schedule.

          (h) NSI has never maintained an employee stock ownership plan (within
     the meaning of Section 4975(e)(7) of the Code) or any other NSI Employee
     Plan that invests in NSI stock.

          (i) Since December 31, 1999, NSI has not proposed nor agreed to any
     increase in benefits under any NSI Employee Plan (or the creation of new
     benefits) or change in employee coverage which would materially increase
     the benefits under or the expense of maintaining any NSI Employee Plan.

          (j) NSI has no current liability based upon, arising out of or
     relating to the classification of any individual as an independent
     contractor or "leased employee" (within the meaning of Section 414(n) of
     the Code) rather than as an employee, and no facts exist as a result of
     which NSI could have any such liability.

          (k) The consummation of the transactions contemplated hereby, either
     alone or in combination with another event, will not result in (i) any
     payment (including, without limitation, severance, unemployment
     compensation or bonus payments) becoming due to any director, officer,
     employee or consultant of NSI, (ii) any increase in the amount of
     compensation or benefits payable in respect of any director, officer,
     employee or consultant of NSI, (iii) any acceleration of the vesting or
     timing of payment of any benefits or compensation payable in respect of any
     director, officer, employee or consultant of NSI or (iv) any "parachute
     payment" within the meaning of Section 280G of the Code in respect of any
     director, officer, employee or consultant of NSI. No NSI Employee Plan
     provides benefits or payments contingent upon, triggered by, or increased
     as a result of a change in the ownership or effective control of NSI.

     3.18 Restrictions on Business Activities. Except for this Agreement or as
set forth in Section 3.18 of the NSI Disclosure Schedule, to NSI's knowledge,
there is no agreement, judgment, injunction, order or decree binding upon NSI
which has or would reasonably be expected to have the effect of prohibiting or
impairing the conduct of business by NSI as


                                       27
<PAGE>

currently conducted by NSI, except for any prohibition or impairment as would
not reasonably be expected, individually or in the aggregate, to have a Material
Adverse Effect.

     3.19 Title to Property. Except as set forth in Section 3.19 of the NSI
Disclosure Schedule, NSI has good title to all of its real properties and other
assets, free and clear of all liens, charges and encumbrances, except for
Permitted Liens and liens for taxes not yet due and payable and Liens which
secure indebtedness reflected in the Interim Balance Sheet; and, all leases
pursuant to which NSI leases from others amounts of real or personal property,
are in good standing, valid and effective in accordance with their respective
terms, and there is not, to the best knowledge of NSI, under any of such leases,
any existing default or event of default (or event which with notice or lapse of
time, or both, would constitute a default).

     alleged deficiency in any Tax, there are no pending or, to NSI's knowledge,
     threatened audits or investigations for or relating to any liability in
     respect of any Taxes, and NSI has not been notified in writing of any
     proposed Tax claims or assessments against NSI (other than in each case,
     claims or assessments for which adequate reserves in the Interim Balance
     Sheet have been established or which are being contested in good faith or
     are immaterial in amount). NSI has not executed any waivers or extensions
     of any applicable statute of limitations to assess any amount of Taxes. NSI
     has not been audited by the IRS for any taxable year. There are no
     outstanding requests by NSI for any extension of time within which to file
     any Tax Return or within which to pay any amount of Taxes shown to be due
     on any Tax Return. There are no liens for Taxes on the assets of NSI except
     for statutory liens for current Taxes not yet due and payable. Except as

     change in method of accounting or otherwise; (v) except with respect to the
     Joint Ventures, NSI is not a party to any joint venture, partnership or
     other arrangement or


                                       28

     contract which is or is reasonably likely to be treated as a partnership
     for federal income tax purposes; (vi) none of NSI's property is treated as

     280G of the Code; (ix) NSI has qualified for and properly elected S

cause any representation or warranty of such party contained in this Agreement
to be materially untrue or inaccurate, (ii) any failure of (A) NSI or Pironti or
(B) NSI Merger Sub or Parent, as the case may be, materially to comply with or

     5.4 No Solicitation.

          (a) NSI shall not, directly or indirectly, through any officer,

of this Agreement, during the period from the date hereof to the Effective Time,
NSI and the Stockholder shall use their reasonable best efforts to take, or
cause to be taken, all appropriate action, and to do, or cause to be done, all
things proper, necessary or advisable under applicable law and regulations to

     respective territories and possessions, except that the Restricted Area
     shall be worldwide with respect to any Competitive Activity involving the

          "Restriction Period" means the period of time (subject to extension
     pursuant to Section 5.6(e) below), commencing on the Effective Date and
     expiring on the earlier of (x) the fifth anniversary of the Effective Date
     or (y) the second anniversary of the termination of Pironti's employment.

          (a) During the Restriction Period, Pironti shall not, directly or
     indirectly, whether as a sole practitioner, owner, partner, shareholder,
     investor, employee, employer, venturer, independent contractor, consultant

<PAGE>

     by any Person. Further, during the Restriction Period, Pironti shall not

     restrictions of this Section 5.6 are reasonable and necessary for the
     protection of the legitimate interests of the Parent Company Group. Each of
     the parties further acknowledges that the provisions and restrictions of
     this Section 5.6 are unique and that any breach or threatened breach of any
     of such provisions or restrictions will provide the Parent Company Group
     with no adequate remedy at law, and the result will be irreparable harm to
     the Parent Company Group. Therefore, the parties hereto agree that upon a
     breach or threatened breach of the provisions or restrictions of this
     Section 5.6, the Parent Company Group shall be entitled, in addition to any
     other rights and remedies which may be available to it, to institute and
     maintain proceedings at law or in equity, to recover damages, to obtain an
     equitable accounting of all earnings, profits or other benefits resulting
     from such breach or threatened breach and to obtain specific performance or
     a temporary and permanent injunction.

          (d) If Pironti violates any restrictive covenant contained herein and
     a member of the Parent Company Group institutes action for equitable
     relief, such member, as a result of the time involved in obtaining such
     relief, shall not be deprived of the benefit of the full Restriction
     Period. Accordingly, the Restriction Period shall be deemed to have the
     duration specified in Section 5.6(a), computed from and commencing on the
     date on which relief is granted by a final order from which there is no
     appeal, but reduced, if applicable, by the length of time between the date
     the Restriction Period commenced and the date of the first violation of any
     restrictive covenant by Pironti.

          (e) Each of the provisions hereof including, without limitation, the
     periods of time, geographic areas and types and scopes of duties of, and
     restrictions on the activities of, the parties hereto specified herein are
     and are intended to be divisible, and if any portion thereof (including any
     sentence, clause or word) shall be held contrary to law or invalid or
     unenforceable in any respect in any jurisdiction, or as to one or more
     periods of time, areas or business activities or any part thereof, the
     remaining provisions shall not be affected but shall remain in full force
     and effect, and any such invalid or unenforceable provision shall be
     deemed, without further action on the part of any party hereto or other
     Person, modified and amended to the minimum extent necessary to render the
     same valid and enforceable in such jurisdiction.


                                       40

          (f) Pironti acknowledges and agrees that (i) compliance with the
     restrictive covenants set forth herein would not prevent him from earning a
     living that involves his training and skills without relocating, but only
     from engaging in unfair competition with, misappropriating a corporate
     opportunity of, or otherwise unfairly harming the Parent Company Group and
     (ii) the restrictive covenants set forth herein are intended to provide a
     minimum level of protection necessary to protect the legitimate interests
     of the Parent Company Group. In addition, the parties acknowledge that
     nothing herein is intended to or shall, limit, replace or otherwise affect
     any other rights or remedies at law or in equity for protection against

     defamation of the Parent Company Group, or for protection of any other
     rights or interest of the Parent Company Group.

the Effective Time, NSI will assign the Apartment Lease to Pironti and Pironti
will assume all obligations and liabilities of NSI under the Apartment Lease
from and after the Effective Time will pay or otherwise discharge in full when

that each Party may, without the prior consent of any other, issue such press
release or make such public statement or filing as may upon the advice of
counsel be required by law, but only after providing the other Parties with
notice of such intent promptly upon reaching the conclusion that any such
release, statement, or filing is required.

     6.4 Conveyance Taxes, etc. All Taxes (other than Shareholder Taxes), and
all recording, registration, or other fees which become payable in connection

     ends on the Effective Date as a result of the NSI Merger.

          (d) Pironti and Parent shall provide each other with such cooperation
     and information as any of them may reasonably request in connection with
     tax matters, including the preparation of tax returns, tax audits, and

further action is necessary or desirable to carry out the purposes of this
Agreement and to vest the NSI Surviving Corporation with full right, title and


                                       42

NSI and NSI Merger Sub, the officers and directors of NSI and NSI Merger Sub
immediately prior to the Effective Time are fully authorized in the name of
their respective corporations or otherwise to take, and will take, all such
lawful and necessary action. Nothing contained in this Agreement shall require
Parent to divest, abandon, or take similar action with respect to any assets
(tangible or intangible) of Parent, NSI Merger Sub, NSI, NSI Surviving
Corporation or any of Parent's subsidiaries.

     6.7 Tax Reporting of Transaction. The Stockholder and the Parent shall
report the NSI Merger for all Tax purposes as a "reorganization' within the

          Letter of Credit shall not have been increased to the Full Note Amount
          on or before one day after the 6 month anniversary of the Effective
          Date or (y) Parent shall have failed to satisfy its obligations under
          subsections (i) or (ii) above, the holders of the Purchase Note and of
          the Negotiable Purchase Note, those having the


                                       43

          any further notices or passage of time.

          (b) Effect of Default prior to Delivery of Letter of Credit. If prior
     to the delivery of a Purchase Note Letter of Credit having a face amount
     equal to the Full Note Amount there shall occur an Event of Default under

     the Purchase Note and of the Negotiable Purchase Note, those having the
     Stockholder JV Entitlements and Pironti shall have the Acceleration Rights
     set forth in subsection (c) below without the requirement for any further

          the Purchase Note and the Negotiable Purchase Note, and the holders
          thereof shall have the rights thereunder set forth in Section 3
          thereof;

               (ii) Those having the Stockholder JV Entitlements shall have the
          rights of acceleration thereto set forth in Section 2.9 (d)(i) hereof;
          and

               (iii) Good Reason shall be deemed to have occurred under Section
          5(d) of the Pironti Employment Agreement and Pironti shall have the
          right to terminate the Pironti Employment Agreement in accordance with
          Section 4(f) thereof. If Pironti terminates the Pironti Employment
          Agreement by reason hereof, the Non-competition provisions of Section
          5.6 hereof and Section 5.6 of the PCM Merger Agreement shall
          immediately terminate and be of no further force and effect; and there

     hereby shall have been obtained and made by NSI, including the consent of
     the Consentors to the NSI Merger and to all of the other foregoing actions,

     filings attached as exhibits to such certificate. For purposes of this
     Section 7.2(c): (i) the failure to receive such consents from either of the

     Surviving Corporation and (ii) any consent (other than the consent of the
     landlord with respect to the premises located at 230 Fifth Avenue, New
     York, NY) that is conditioned on any material change in the terms of the

     Parent expressly agrees in writing to such change.

          (d) Secretary's Certificate. NSI shall have delivered to Parent a
     certificate of the Secretary or an Assistant Secretary of NSI, dated as of

     thereto); (ii) that the Articles of Incorporation and By-laws of NSI
     attached to the Secretary's certificate are true, complete, and correct and
     are in full force and effect as of the Effective Date; and (iii) as to the
     incumbency and specimen signature of the officers of NSI executing this
     Agreement and other documents to be executed on behalf of NSI in connection

     (iii) the Dividends Payable, and (iv) amounts that are deducted in arriving

     indebtedness to the applicable obligor for cancellation.

          (f) Releases. Pironti and each of the Permitted Transferees shall have

     all claims of Pironti or such Transferee, as the case may be, against NSI
     and the NSI Surviving Corporation other than claims arising under this
     Agreement or pursuant to the Employment Agreement between Pironti or such
     Transferee, as the case may be, and NSI Surviving Corporation.

     occurred with respect to NSI following the date hereof.

          (h) Cessation of Franchise Tax Report. NSI shall have filed a

     Taxes required to be paid as of the Effective Date in connection with such

     Time, with the same force and effect as if made on and as of the Effective
     Time, except for (i) changes contemplated by this Agreement and (ii) those

     shall have received a certificate of Parent to such effect signed by the
     President or Chief Financial Officer of Parent with signed originals of all

8.   Termination.

     8.1 Termination. This Agreement may be terminated at any time prior to the
Effective Time, notwithstanding approval thereof by the Stockholder:

          (a) by mutual written consent of the Parties;

          (b) by either Parent or NSI if the NSI Merger and the PCM Merger shall
     not have been consummated by the Merger Deadline (other than for the
     reasons set forth in Sections 8.1(d), (e), or (f)); provided, however, that
     the right to terminate this Agreement under this Section 8.1(b) shall not
     be available to any Party whose failure to fulfill any obligation under
     this Agreement has been the cause of, or resulted in, the failure of the
     NSI Merger to be consummated on or prior to such date;

          (c) by either Parent or NSI if a court of competent jurisdiction or
     governmental, regulatory or administrative agency or commission shall have
     issued a nonappealable final order, decree or ruling or taken any other
     nonappealable final action having the effect of permanently restraining,
     enjoining or otherwise prohibiting the NSI Merger;

          (d) by (i) Parent or (ii) by NSI, if any representation or warranty of
     NSI or the Stockholder, or Parent or NSI Merger Sub, respectively, set
     forth in this Agreement shall have been untrue when made, such that the
     conditions set forth in Sections 7.2(a) or 7.3(a), as the case may be,
     would not be satisfied (a "Terminating Misrepresentation"); provided, that,
     if such Terminating Misrepresentation is curable through the exercise of
     its commercially reasonable efforts and is cured prior to the date two (2)
     days prior to the Effective Date by Parent or NSI, as the case may be,
     neither Parent nor NSI, respectively, may terminate this Agreement under
     this Section 8.1(d) (it being understood that if such Terminating
     Misrepresentation consists of the omission of any information from a
     disclosure schedule, then such Terminating Misrepresentation cannot be
     cured by an amendment or supplement to such disclosure schedule unless the
     other party agrees in writing to waive such Terminating Misrepresentation
     for the purposes of this Section 8.1(d));

          (e) by (i) Parent, if any representation or warranty of NSI or the
     Stockholder shall have become untrue such that the condition set forth in
     Section 7.2(a) would not be satisfied, or (ii) by NSI, if any
     representation or warranty of Parent or NSI Merger Sub shall have become
     untrue such that the condition set forth in Section 7.3(a), would not be
     satisfied (in either case, a "Terminating Change"), in either case other
     than by reason of a Terminating Breach (as hereinafter defined); provided,
     that, if any such Terminating Change is curable through the exercise of its
     commercially reasonable efforts and is cured prior to the date two (2) days
     prior to the Effective Date by NSI or Parent, as the


                                       48
<PAGE>

     case may be, neither Parent nor NSI, respectively, may terminate this
     Agreement under this Section 8.1(e);

          (f) by (i) Parent or by (ii) NSI, upon a breach of any covenant or
     agreement on the part of NSI or the Stockholder, or Parent or NSI Merger
     Sub, respectively, set forth in this Agreement such that the conditions set
     forth in Sections 7.2(b) or 7.3(b), as the case may be, would not be
     satisfied (a "Terminating Breach"); provided, that, except for any breach
     of NSI's obligations under Section 5.4, if such Terminating Breach is
     curable through the exercise of its commercially reasonable efforts and is
     cured prior to the date two (2) days prior to the Effective Date by NSI or
     Parent, as the case may be, neither Parent nor NSI, respectively, may
     terminate this Agreement under this Section 8.1(f); or

          (g) by Parent or NSI, if Parent or PCM, respectively, has the right to
     terminate PCM Merger Agreement pursuant to Section 8.1 thereof.

     8.2 Effect of Termination.

          (a) In the event of the termination of this Agreement pursuant to
     Section 8.1, this Agreement shall forthwith become void and there shall be
     no liability on the part of any Party or any Party's affiliates, directors,
     officers or shareholders, except as set forth in Section 6.2, Section
     8.2(b) or Section 9.6.

          (b) In the event of the termination of this Agreement by NSI or Parent
     (such party, the "Terminating Party"): (i) pursuant to Section 8.1(b) if
     such termination results from the failure or refusal of the other party
     (the "Breaching Party") to close on or prior to the Merger Deadline under
     circumstances in which the Terminating Party is not in material breach of
     its representations, warranties, covenants or obligations hereunder, (ii)
     pursuant to Section 8.1(d) as a result of a Terminating Misrepresentation
     by the Breaching Party, (iii) pursuant to Section 8.1(e) as a result of a
     Terminating Change (but only if such Terminating Change resulted from any
     willful action or willful failure to take action on the part of the
     Breaching Party or any Affiliate of the Breaching Party, or (iv) pursuant
     to Section 8.1(f) as a result of a Terminating Breach by the Breaching
     Party, then within two business days following the date of termination, the
     Breaching Party shall pay the Terminating Party the sum of $400,000 as
     liquidated damages, and not as a penalty, in lieu of any and all other
     remedies that the Terminating Party may have against the Breaching Party;
     provided, however, that the aggregate amount payable pursuant to this
     Section 8.2(b) and Section 8.2(b) of PCM Merger Agreement shall not exceed
     $400,000.

9.   Indemnification.

     9.1 Indemnification by the Stockholder. The Stockholder shall indemnify and
hold harmless Parent, NSI Merger Sub and their respective officers, directors,

     described in Schedule 9.1(a) hereto (as to which this proviso shall not
     apply), the Stockholder shall have no obligation to indemnify any Parent
     Indemnified Person with respect to any such untrue representation or

     or other obligation of PCM, the Stockholder or the Permitted Transferees,
     under PCM Merger Agreement or under the Exhibits attached thereto or under
     the certificates and documents delivered pursuant thereto (including
     certificates of officers of PCM acting in their capacities as such),
     provided that, except with respect to the matters described in Schedule
     9.1(a) thereto (as to which this proviso shall not apply), the Stockholder
     shall have no obligation to indemnify any Parent Indemnified Person with
     respect to any such untrue representation or warranty if Parent had
     knowledge that such representation and warranty was untrue on the Effective
     Date, and the burden of proof shall be on the Stockholder to prove that
     Parent had such knowledge;

          (c) All Losses arising out of or relating to: (i) items specifically

     to the Effective Time or the failure of such plans to comply with
     applicable laws or


                                       50
<PAGE>

     If the NSI Merger occurs, (i) the Stockholder shall have no obligation to
     indemnify the Parent Indemnified Persons: (x) for the first $400,000 (the
     "General Deductible") of aggregate Losses described in clauses (a), (b),

     Deductible, and (ii) the obligation of the Stockholder with respect to
     Losses relating to Benefits Issues shall not exceed an amount equal to the
     sum of: (x) the amount that would be reasonably required solely to cause

     thereto; (y) the amount required to satisfy any liabilities arising out of
     or relating to the failure of any such Employee Plan so to comply,

     including reasonable fees and disbursements of counsel specifically
     allocable to the resolution of the Benefits Issues.

     9.2 Indemnification by Parent. Parent agrees to indemnify and hold harmless
the Stockholder, NSI, and its officers, directors, stockholder, employees,
attorneys, accountants, affiliates and agents ("NSI Indemnified Persons") from
and against (and shall on demand reimburse them for):


                                       51
<PAGE>

          (a) any and all Losses suffered or incurred, directly or indirectly,
     by a NSI Indemnified Person with respect to, resulting from or arising out
     of any untrue representation or warranty made by Parent, or the failure,
     breach or nonfulfillment of any representation, warranty, covenant,
     agreement or other obligation of Parent, hereunder or under any other
     agreement, document, certificate or instrument entered into pursuant
     hereto; provided that Parent shall have no obligation to indemnify any NSI
     Indemnified Person with respect to any such untrue representation or
     warranty if the Stockholder had knowledge that such representation and
     warranty was untrue on the Effective Date and the burden of proof shall be
     on Parent to prove that NSI had such knowledge; or

          (b) any and all actions, suits, proceedings, claims, demands,
     assessments, judgments, costs and expenses, including, reasonable legal
     fees and expenses, incident to any of the foregoing or incurred in
     investigating or attempting to avoid the same or to oppose the imposition
     thereof, or in enforcing this indemnity.

     9.3 Assumption of Defense. An indemnified party shall promptly give notice
to each indemnifying party after obtaining knowledge of any matter as to which
recovery may be sought against such indemnifying party because of any indemnity
set forth in this Section 9 if such indemnity shall arise from the claim of a
third party and shall permit such indemnifying party to assume the defense of
any such claim or any proceeding resulting from such claim; provided, however,
that failure promptly to give any such notice shall not affect the
indemnification provided under this Section 9, except to the extent such
indemnifying party shall have been actually prejudiced as a result of such
failure (in which event the amount of any indemnity payment required to be made
by the indemnifying party shall be reduced by the amount of any losses sustained
by such party as a result of such failure). Notwithstanding the foregoing, an
indemnifying party may not assume the defense of any such third-party claim if
it does not demonstrate to the reasonable satisfaction of the indemnified party
that it has adequate financial resources to defend such claim and pay any and
all Losses that may result therefrom, or if the claim (a) is reasonably likely
to result in imprisonment of the indemnified party or (b) is reasonably likely
to result in an equitable remedy which would materially impair the indemnified
party's ability to exercise its rights under this Agreement, or impair Parent's
right or ability to conduct the Business as it is currently conducted. If an
indemnifying party assumes the defense of such third party claim, such
indemnifying party shall agree prior thereto, in writing, that it is liable
under this Section 9 to indemnify the indemnified party in accordance with the
terms contained herein in respect of such claim, shall conduct such defense
diligently, shall have full and complete control over the conduct of such
proceeding on behalf of the indemnified party and shall, in his, her or its sole
discretion, have the right to decide all matters of procedure, strategy,
substance and settlement relating to such proceeding; provided, however, that
any counsel chosen by such indemnifying party to conduct such defense shall be
reasonably satisfactory to the indemnified party. The indemnified party may
participate in such proceeding and retain separate co-counsel at its sole cost
and expense and the indemnifying party will not without the written consent of
the indemnified party consent to the entry of any judgment or enter into any
settlement with respect to the matter which does not include a provision whereby
the plaintiff or the claimant in the matter releases the indemnified party from
all liability with respect thereto. Failure by an indemnifying party to notify
the indemnified party of its election to defend any such claim or proceeding by
a third party within thirty (30) days after notice thereof shall have


                                       52
<PAGE>

been given to such indemnifying party by the indemnified party shall be deemed a
waiver by such indemnifying party of its right to defend such claim or action.

     9.4 Non-Assumption of Defense. If no indemnifying party is permitted or
elects to assume the defense of any such claim by a third party or proceeding
resulting therefrom, the indemnified party shall diligently defend against such
claim or litigation in such manner as it may deem appropriate and, in such
event, if such claim is one for which the indemnifying party is in fact
responsible, the indemnifying party or parties shall promptly reimburse the
indemnified party for all reasonable out-of-pocket costs and expenses, legal or
otherwise, incurred by the indemnified party and its affiliates in connection
with the defense against such claim or proceeding. Any counsel chosen by such
indemnified party to conduct such defense must be reasonably satisfactory to the
indemnifying party or parties, and only one counsel shall be retained to
represent all indemnified parties in an action (except that if litigation is
pending in more than one jurisdiction with respect to an action, one such
counsel may be retained in each jurisdiction in which such litigation is
pending). The indemnified party shall not settle or compromise any such claim
without the written consent of the indemnifying party, which shall not be
unreasonably withheld.

     9.5 Indemnified Party's Cooperation as to Proceedings. The indemnified
party will cooperate in all reasonable respects with any indemnifying party in
the conduct of any proceeding as to which such indemnifying party assumes the
defense. For the cooperation of the indemnified party pursuant to this Section
9.5, if such claim is one for which the indemnifying party is in fact
responsible, the indemnifying party or parties shall promptly reimburse the
indemnified party for all reasonable out-of-pocket costs and expenses, legal or
otherwise, incurred by the indemnified party or its affiliates in connection
therewith as such costs and expenses are incurred.

     9.6 Limitation on Losses.

          (a) The amount of any Loss incurred or suffered by a person shall be
     reduced by any insurance proceeds received by such person in connection
     with the breach, failure or other event which gave rise to such Loss (net
     of any costs incurred by such person in connection with the collection of
     such insurance proceeds). In connection therewith, for so long as the
     Stockholder has any obligations pursuant to this Section 9 or Section 9 of
     the PCM Merger Agreement, Parent, NSI Surviving Corporation and/or PCM
     Surviving Corporation will maintain or cause to be maintained with
     financially sound and reputable insurers that have a rating of "A" or
     better as established by Best's Rating Guide (or an equivalent rating with
     such other publication of a similar nature as shall be in current use),
     insurance coverage comparable or superior to the coverage described on
     Schedule 9.6 (a) hereto with respect to NSI and PCM.

          (b) The amount of any Loss incurred or suffered by any Indemnified
     Party (i) shall be increased by any Tax incurred or reasonably expected to
     be incurred as a result of or related to any such Loss, including any Tax
     related to the inclusion in gross income of insurance proceeds or a
     payment, (ii) shall be reduced by any Tax benefit realized or reasonably
     expected to be realized as a result of or related to any such Loss, and
     (iii) shall


                                       53

     be increased by interest computed at the rate of 7% per annum from the date
     such Loss is incurred or suffered to the date of payment.

          (c) The breach of any representation and warranty or agreement by the
     Stockholder or NSI set forth in Section 3.8, 3.9 or 5.2 hereof shall not be
     deemed to have resulted in a Loss to the Parent Indemnified Parties if such
     breach resulted in an overpayment of NSI Merger Consideration or PCM Merger
     Consideration to the Stockholder and/or the Permitted Transferees or of the
     Overage or any other amount payable to Pironti or the Stockholder and/or
     such Permitted Transferees and such overpayment is in any such case
     subsequently corrected pursuant to an adjustment in accordance with Section
     2.8(c) hereof or Sections 2.8 (c) or 2.9 of the PCM Merger Agreement, as
     the case may be; provided, however, that the foregoing exclusion shall not
     apply to any Third Party Liability arising out of or relating to any such
     breach. For avoidance of doubt, any adjustments pursuant to Section 2.8(c)
     hereof or Sections 2.8(c) or 2.9 of the PCM Merger Agreement shall not be
     counted toward satisfaction of the General Deductible in Section 9.1 hereof
     and shall not be subject to the maximum liability provisions set forth in
     Sections 9.6(d) and (e).

          (d) The maximum aggregate amount for which the Stockholder shall be
     liable hereunder and under PCM Merger Agreement shall be (in each case such
     that Parent and NSI hereunder and Parent and PCM under PCM Merger Agreement
     shall not under any circumstances have any recourse against the Stockholder
     pursuant to this Agreement and PCM Merger Agreement in excess of the named
     amount in the aggregate):

               (i) If the NSI Merger does not occur, $400,000 (as provided in
          Section 8.2(b) hereof); and

               (ii) If the NSI Merger occurs, $7,500,000;

          provided, however, that if the NSI Merger occurs, the foregoing
          limitation shall not apply to Losses arising out of or relating to
          third party claims, including proceedings brought by any governmental
          entity.

          (e) The maximum aggregate amount for which Parent hereunder and Parent
     and under PCM Merger Agreement shall be liable shall be (in each case such
     that the Stockholder hereunder and the Stockholder under PCM Merger
     Agreement shall not under any circumstances have any recourse against
     Parent, NSI Merger Sub and PCM Merger Sub pursuant to this Agreement and
     PCM Merger Agreement in excess of the named amount in the aggregate):

               (i) If the NSI Merger does not occur, $400,000 (as provided in
          Section 8.2(b) hereof);

               (ii) From and after the Effective Date and until the Purchase
          Note and Negotiable Purchase Note have been paid, $6,600,000; and

          Negotiable Purchase Note have been paid, $3,000,000;


                                       54
<PAGE>

          provided, however, that if the NSI Merger occurs, the foregoing
          limitation shall not apply to Losses arising out of or relating to
          third party claims, including proceedings brought by any governmental
          entity.

          (f) No Parent Indemnified Person shall have recourse for
     indemnification under Section 9.1(b) above and beyond the time frames set
     forth in PCM Merger Agreement or for indemnification under Section 9.1(a)
     above beyond the time frames set forth below:

               (i) in the case of Sections 3.1, 3.3, 3.4 and 3.5, there shall be
          no such time limit,

               (ii) in the case of Sections 3.17, 3.20, 3.21 and 3.24, until
          thirty (30) days following the expiration of the applicable statute of
          limitations with respect to the matter to which the claim relates,

               (iii) in the case of all other provisions of Section 3, until
          June 30, 2002.

          (g) No NSI Indemnified Person shall have recourse for indemnification
     under Section 9.2(a) beyond the time frames set forth below:

               (i) in the case of Sections 4.1, 4.3, 4.4 and 4.8, there shall be
          no such time limit, and

               (ii) in the case of all other provisions of Section 4, beyond the
          third anniversary of the Effective Date.

     9.7 Dispute Resolution Procedure. In the event that any of the Parent
Indemnified Person is seeking indemnification pursuant to Section 9.1 hereof or
Section 9.1 of the PCM Merger Agreement, such Parent Indemnified Person, (the
"Notifying Person") shall notify Stockholder thereof, which notice (the
"Indemnity Notice") shall set forth in reasonable detail the facts and
circumstances giving rise to the Losses for which indemnity is sought, the
amount thereof including the basis for the calculation of the Losses, including
without limitation the amount of costs and expenses incurred by such Parent
Indemnified Person, and, if then known, the amount of any adjustment to or
deduction from the amount of Losses subject to indemnification as a result of
the deductibles established pursuant to Section 9.1 hereof or Section 9.1 of the
NSI Merger Agreement or the provisions of Section 9.6 hereof or Section 9.6 of
the NSI Merger Agreement, as the case may be. If Stockholder disagrees with any
matter set forth in an Indemnity Notice, he shall provide the Notifying Person
with notice of such disagreement (the "Indemnity Dispute Notice") within thirty
(30) days following the date on which the applicable Indemnity Notice was given
to Stockholder. Such Indemnity Dispute Notice shall set forth in reasonable
detail the nature and basis of such disagreement together with Stockholder's
view, if any, of the amount of any indemnity payment to which the Parent
Indemnified Person should be entitled. If Stockholder does not deliver an
Indemnity Dispute Notice within such thirty (30) day period, Stockholder shall
be deemed to have agreed with the matters set forth in the Indemnity Notice. If
Stockholder timely provides a Dispute Notice, then (a) the representatives of
Stockholder and the Notifying Person shall meet promptly and attempt in good
faith to resolve such dispute. If such representatives cannot mutually resolve
such dispute within ten (10) days


                                       55
<PAGE>

after the date on which the Indemnity Dispute Notice is given, either party may
submit such dispute for final and binding arbitration in The City of New York by
a panel of three (3) arbitrators (the "Arbitrators") pursuant to the commercial
arbitration rules then prevailing of the American Arbitration Association
("AAA"), as supplemented herein, and judgment upon the award rendered by the
arbitrators may be entered in any court having jurisdiction thereof. Pending
final award, Arbitrator compensation and expenses shall be advanced equally by
Stockholder on the one hand and the parties seeking indemnification, on the
other hand. The Parent Indemnified Person and Stockholder shall instruct the AAA
to hold an administrative conference with counsel for the parties within twenty
(20) days after the filing of the demand for arbitration. The parties and the
AAA shall thereafter cooperate in order to complete the appointment of the
Arbitrrators as quickly as possible. Within ten days after all three Arbitrators
have been appointed, the Parent Indemnified Person and Stockholder shall seek to
have an initial meeting among the Arbitrators and counsel for the parties shall
be held for the purpose of establishing a plan for administration of the
arbitration, including (a) scope, timing and types of discovery, which may at
the discretion of the Arbitrators include production of documents in the
possession of the parties, but may not without consent of all parties include
depositions; (c) exchange of documents and filing of detailed statement of claim
and prehearing memoranda; (c) schedule and place(s) of hearings; and (d) any
other matters that may promote the efficient, expeditious and cost-effective
conduct of the proceeding. The Arbitrators shall not be permitted to award
Losses in an amount in excess of those set forth in the Indemnity Notice or less
than the amount set forth in the Indemnity Dispute Notice, except in either case
with respect to amounts constituting adjustments or deductibles which were not
known at the time the applicable notice was given. The Arbitrators shall be
instructed to allocate and award all costs and fees (including costs incurred by
the Parent Indemnified Person and Stockholder) based upon their relative success
in arbitration).

     9.8 Setoff. Parent or NSI Surviving Corporation may set off any amount
payable to it by the Stockholder pursuant to this Section 9 or Section 9 of PCM
Merger Agreement against the payment of any amount due under the Purchase Note;
provided, however, that no such setoff shall be permitted until the resolution
of any dispute respecting the obligation to pay any such amount by operation of
Section 9.7 above. Any failure by NSI Surviving Corporation to pay any principal
or interest otherwise due under the Purchase Note solely as a result of a setoff
effected in accordance with the provisions of this Section 9.8 shall not
constitute an Event of Default under the Purchase Note.

     9.9 Option to Make Part Payment in Stock. Up to 35% of the aggregate of the
amount payable by the Stockholder pursuant to this Section 9 and pursuant to
Section 9 of PCM Merger Agreement may be paid in shares of Parent Common Stock,
with each share of Parent Common Stock valued at the Current Market Price.

     9.10 Exclusive Remedies. Each Party's sole recourse against each of the
other Parties under this Agreement or in respect of the transactions
contemplated by this Agreement shall be pursuant to and under Section 8 and this
Section 9, and subject to the limitations and restrictions contained herein and
therein.

Sections of the Company Disclosure Schedule or the Parent Disclosure Schedule,

therein as to which such disclosure is relevant provided that such relevance is
reasonably apparent. No statement contained in any certificate or schedule
required to be furnished by any Party pursuant to this Agreement, including such
Party's Disclosure Schedule, shall contain any untrue statement of a material

order to make the other statements contained therein not misleading.

     10.7 Severability. If any term or other provision of this Agreement is

policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated hereby is not affected in any manner adverse to
any party. Upon a determination that any term or other provision is invalid,
illegal or incapable of being enforced, the parties hereto shall negotiate in
good faith to modify this Agreement so as to effect the original intent of the
Parties as closely as possible in an


                                       58

acceptable manner to the end that transactions contemplated hereby are fulfilled

written consent of the other Party shall be void and of no effect; provided,
that (i) all or any of the rights of the Parent Parties hereunder may be
assigned to any Affiliate of Parent or to any person who acquires all or a
substantial portion of the business of Parent, except that no such assignment
shall be permitted if, solely as a result of such assignment, the NSI Merger
would not qualify as a tax-free reorganization pursuant to Section 368(a)(1) of
the Code, (ii) all of any of the rights of the Parent Parties hereunder may be
assigned as collateral security to one or more persons which provide financing
for the transactions contemplated hereby and by the PCM Merger Agreement, and

assignment shall relieve the assigning Party of its obligations hereunder.

     10.10 Parties in Interest. This Agreement shall be binding upon and inure
solely to the benefit of each Party, and nothing in this Agreement, express or
implied, is intended to or shall confer upon any other person any right, benefit
or remedy of any nature whatsoever under or by reason of this Agreement,
including by way of subrogation.

     10.11 Failure or Indulgence Not Waiver; Remedies Cumulative. No failure or
delay on the part of any Party in the exercise of any right hereunder shall
impair such right or be construed to be a waiver of, or acquiescence in, any
breach of any representation, warranty or agreement herein, nor shall any single
or partial exercise of any such right preclude other or further exercise thereof
or of any other right. All rights and remedies existing under this Agreement are
cumulative to, and not exclusive of, any rights or remedies otherwise available.
