STOCK PURCHASE AND SALE AGREEMENT

Stock Purchase and Sale Agreement, dated as of June 24, 2003, by and among NPTest Holding Corporation, a Delaware corporation (“Parent”), NPTest Acquisition Corporation, a Delaware corporation (“Purchaser”) and a wholly owned subsidiary of Parent, Schlumberger Technology Corporation, a Texas corporation (“STC”), Schlumberger Technologies, Inc., a Delaware corporation and a wholly owned subsidiary of STC (“STI”) and Schlumberger B.V., a corporation organized under the laws of The Netherlands (“SBV” and, together with STI, the “Sellers”). Certain capitalized terms used in this Agreement have the meanings assigned to them in Article IX.

WHEREAS, STI owns all of the issued and outstanding shares of common stock, par value $0.01 (the “NPT Shares”), of NPTest, Inc., a Delaware corporation (the “US Company”);

WHEREAS, SBV owns all the issued and outstanding equity securities (the “BVI Shares”) of NPTest International Limited, a corporation organized under the laws of the British Virgin Islands (the “BVI Company”);

WHEREAS, the board of directors of each of STI and Purchaser has approved, and deems it advisable and in the best interests of its respective stockholders for Purchaser to consummate the acquisition of the US Company, which acquisition is to be effected by the purchase of all the NPT Shares by Purchaser from STI upon the terms and subject to the conditions set forth herein; and

WHEREAS, the board of directors or equivalent corporate governing body of each of SBV and Purchaser has approved, and deems it advisable and in the best interests of its respective shareholders for Purchaser to consummate, the acquisition of the BVI Company by Purchaser, which acquisition is to be effected by the purchase of all the issued and outstanding BVI Shares by Purchaser from SBV upon the terms and subject to the conditions set forth herein.

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties, covenants and agreements set forth herein, intending to be legally bound hereby, the parties hereto agree as follows:

ARTICLE I

PURCHASE AND SALE

Section 1.1 Sale and Transfer.

(a) Subject to the terms and conditions of this Agreement, at the Closing, STI shall sell, convey, assign, transfer and deliver to Purchaser all of its rights, title and interest to the NPT Shares, free and clear of all Encumbrances, except for any Encumbrance arising under the Securities Act or any applicable state securities laws, and Purchaser shall purchase, acquire and accept the NPT Shares from STI (the “NPT Sale”).

(b) Subject to the terms and conditions of this Agreement, at the Closing, SBV shall sell, convey, assign, transfer and deliver to Purchaser all of its rights, title and interests to all the BVI Shares, free and clear of all Encumbrances, except for any Encumbrance arising under the Securities Act or any applicable state securities laws, and Purchaser shall purchase, acquire and accept the BVI Shares from SBV (the “BVI Sale”).

Section 1.2 The Purchase Price. Subject to the terms and conditions of this Agreement, in consideration of the aforesaid sale, conveyance, assignment, transfer and delivery by Sellers to Purchaser of the NPT Shares and the BVI Shares, Purchaser shall pay to Sellers an amount of cash equal to $220,000,000 (the “Initial Cash Consideration”), subject to adjustment in accordance with Section 1.3 and Section 1.4 (the “Purchase Price”), to be allocated between the Sellers as provided in Section 1.5.

Section 1.3 Purchase Price Adjustment.

(a) No later than five business days prior to the Closing Date, Sellers shall prepare and deliver to Purchaser a balance sheet as of June 30, 2003 (the “Initial Balance Sheet”), using line items substantially consistent with those in the December 31, 2002 Balance Sheet included in the Financial Statements, together with a certificate based on such Initial Balance Sheet setting forth Parent’s calculation of Working Capital as of June 30, 2003, which shall be calculated in the manner set forth on Schedule 1.3 (the “Initial Working Capital Schedule”).

(1) Purchaser shall promptly review the Initial Balance Sheet, and the parties agree to discuss in good faith any comments or questions Purchaser may have with respect to the Initial Balance Sheet.

(2) If the amount of “Cash” set forth in the Initial Balance Sheet is less than $4,000,000, the Purchase Price payable by Purchaser at Closing shall be decreased by such shortfall (the “Preliminary Adjustment Amount”).

(3) If the amount of “Cash” set forth in the Initial Balance Sheet is more than $4,000,000, the Purchase Price payable by Purchaser at Closing shall be increased by such excess (the “Preliminary Adjustment Amount”).

(b) As promptly as practicable, but no later than 60 calendar days after the Closing Date, Sellers shall prepare and deliver to Purchaser a balance sheet as of June 30, 2003 (the “Final Balance Sheet”) and Income Statement (the “Final

Income Statement”), together with a certificate based on such Final Balance Sheet setting forth Sellers’ calculation of Working Capital as of June 30, 2003, which shall be calculated in the manner set forth on Schedule 1.3 (the “Final Working Capital Schedule”). The Final Balance Sheet shall be prepared in accordance with GAAP on a basis consistent with the Financial Statements, accompanied by a letter from PricewaterhouseCoopers LLP, which states that they have conducted a review of the Final Balance Sheet in accordance with applicable auditing standards of interim operations and includes negative assurance with respect thereto.

(c) Purchaser may dispute any amounts reflected on the Final Balance Sheet and the Final Working Capital Schedule, but solely on the basis that (i) such documents were not prepared in accordance with GAAP or on a basis consistent with the Initial Balance Sheet or (ii) the mathematical computations or clerical entries are inaccurate; provided that Purchaser shall notify Sellers in writing, within 45 calendar days after Purchaser’s receipt of the Final Balance Sheet, of each disputed item (a “Notice of Dispute”), specifying the amount in dispute and setting forth in reasonable detail each disputed item and amount and the basis for such dispute.

(d) In the event of such a dispute, the Sellers and Purchaser shall attempt to reconcile their differences and any resolution by them as to any disputed amounts shall be final and binding on the parties hereto. If Purchaser and the Sellers are unable to reach a resolution with such effect within 15 calendar days of the delivery of the Notice of Dispute, Purchaser and the Sellers shall submit the items remaining in dispute for resolution by an independent accounting firm of national reputation mutually appointed by Purchaser and the Sellers (the “Independent Accounting Firm”), which shall, within 30 calendar days after submission, determine and report to the parties upon such remaining disputed items and such report shall be final and binding on the parties hereto. The fees and disbursements of the Independent Accounting Firm shall be allocated between the Purchaser on the one hand and the Sellers on the other hand, in the same proportion that the aggregate amount of such remaining disputed items so submitted to the Independent Accounting Firm that is unsuccessfully disputed by each (as finally determined by the Independent Accounting Firm) bears to the total amount of such remaining disputed items so submitted. If Purchaser does not deliver a Notice of Dispute to the Sellers within 45 calendar days of the date of delivery to Purchaser of the Final Balance Sheet, the Final Balance Sheet delivered to Purchaser shall be final and binding upon the parties hereto upon the expiration of such 45 calendar day period.

(e) The following payments shall be made as adjustments to the Purchase Price (each, an “Adjustment Payment”), as applicable:

(1) Sellers shall make a payment to Purchaser equal to the amount of the excess, if any, of $4,000,000 over the amount of “Cash” set forth in the Final Balance Sheet; provided that the amount payable pursuant to this clause (1) shall be less any Preliminary Seller Adjustment Amount already paid by Sellers or plus any Preliminary Purchaser Adjustment Amount previously paid by Purchaser.

(2) Purchaser shall make a payment to Sellers equal to the amount of excess, if any, of the amount of “Cash” set forth in the Final Balance Sheet over $4,000,000; provided that the amount payable pursuant to this clause (2) shall be less any Preliminary Purchaser Adjustment Amount already paid by Purchaser or plus any Preliminary Seller Adjustment Amount previously paid by Sellers.

(3) Sellers shall make a payment to Purchaser equal to the excess, if any, of (A) Target Accounts Receivable minus $2,000,000 over (B) the amount of “Accounts Receivable, Net” set forth in the Final Balance Sheet.

(4) Purchaser shall make a payment to Sellers equal to the excess, if any, of (A) the amount of “Accounts Receivable, Net” set forth in the Final Balance Sheet, over (B) the sum of (i) Target Accounts Receivable and (ii) $2,000,000.

(5) Sellers shall make a payment to Purchaser equal to the excess, if any, of (A) Target Working Capital minus $3,000,000 over (B) the amount of “Total Working Capital” (excluding “Cash” and “Accounts Receivable, Net”) set forth in the Final Working Capital Schedule.

(6) Purchaser shall make a payment to Sellers equal to the excess, if any, of (A) the amount of “Total Working Capital” (excluding “Cash” and “Accounts Receivable, Net”) set forth in the Final Working Capital Schedule, over (B) the sum of (x) Target Working Capital and (y) $3,000,000.

(f) Any Adjustment Payment shall be made within five Business Days of the date on which the Final Balance Sheet becomes final and binding on the parties in accordance with this Section 1.3 and shall be made with interest thereon, calculated at the Interest Rate from the Closing Date to the date of payment. Any Adjustment Payment shall be paid to the Purchaser or Sellers, as applicable, as soon as practicable on the day when due in U.S. Dollars by wire transfer in immediately available funds.

(g) Purchaser and Sellers agree that they will, and agree to cause their respective independent accountants and the Company and each Subsidiary to, cooperate and assist in the preparation of the Final Balance Sheet and in the conduct of the reviews referred to in this Section, including making available, to the extent necessary, books, records, work papers and personnel.

(h) All computations of interest under this Section 1.3 shall be made by the party entitled to receive payment on the basis of a year of 360 days, in each case for the actual number of days, including the first day but excluding the last day) occurring in the period for which such interest is payable. Whenever a payment under

this Section 1.3 shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of interest.

(i) The following terms shall have the following meanings in this Section:

(i) “Target Accounts Receivable” shall mean (A) $54,574,000 plus (B) the excess of Revenue as set forth on the Final Income Statement over $55,043,000, or minus (C) the excess of $55,043,000 over Revenue as set forth on the Final Income Statement.

(ii) “Target Gross Inventory” shall mean (A) $188,386,000 plus (B) the product of 0.7 times the excess of (x) $55,043,000 over (y) Revenue as set forth on the Final Income Statement, or minus (C) the product of 0.7 times the excess of (1) Revenue as set forth on the Final Income Statement over (2) $55,043,000.

(iii) “Target Working Capital” shall mean Target Gross Inventory minus $33,280,000.

Section 1.4 Purchase Price Adjustment For Certain Transactions. The Purchase Price is subject to increase in accordance with and subject to the terms and provisions set forth below.

(a) In the event of a distribution, in whole or in part, by NPTest Holding, LLC (including any successor thereto, “NPT LLC”) to any of its members of any equity securities of the Companies or any consideration received upon the sale, exchange or other transfer thereof or any consideration received upon a dividend or distribution to the holders of the Companies’ equity securities (collectively, the “Company Consideration”), the Purchase Price shall be increased by 15% of the difference, if any, between (i) the Aggregate Distribution Value as of the time of such distribution and (i) the greater of (x) $330 million and (y) the Aggregate Distribution Value immediately prior to such distribution.

For purposes of this subsection, the “Aggregate Distribution Value” means, as of the time of any distribution, the value determined in good faith by NPT LLC, consistent with the value reported to its members, of the Company Consideration then being distributed to its members plus the Aggregate Distribution Value of all Company Consideration previously distributed by NPT LLC to its members; provided, that

(1) in the event of an initial public offering of the Companies, the Aggregate Distribution Value shall, at the option of the Selling Parties, include the value of any Company Consideration not previously distributed by NPT LLC as of the earlier of (x) the date NPT LLC has received Company Consideration of at least $330 million in cash and (y) the first anniversary of the closing of such

initial public offering, in either case, based upon the value of such cash and the average closing prices of the equity securities received for the 10 trading days ending on the trading day preceding such applicable date (the “IPO Option”). The Selling Parties shall have the right to exercise the IPO Option by written notice given to the Purchaser no later than the earlier of (i) 10 business days after the Purchaser gives written notice to the Selling Parties that it has received Company Consideration of at least $330 million in cash and (ii) 10 business days prior to the first anniversary of such initial public offering; provided that the IPO Option shall expire if not exercised by the applicable date, in which event any distribution of Company Consideration otherwise subject to this paragraph shall be governed by the first paragraph of this subsection (a) above and not this subsection (1). If the Selling Parties exercise the IPO Option and receive the related payment therefor, then no further payment shall be due and payable in respect thereof pursuant to this Section 1.4; and

(2) in the event of the merger or acquisition of the Companies or the sale of all or substantially all of the Companies’ assets in which either (A) NPT LLC receives Company Consideration of at least $330 million in cash or (B) NPT LLC receives proceeds consisting only of cash and equity securities that have been registered under the Securities Act or issued pursuant to a Section 3(a)(10) exemption therefrom (“freely tradeable securities”), the Aggregate Distribution Value shall, at the option of the Selling Parties, include the value of any Company Consideration not previously distributed by NPT LLC as of the earlier of (x) the date NPT LLC has received Company Consideration of at least $330 million in cash and (y) the first anniversary of the closing of such transaction, in either case, based upon the value of such cash or other consideration and the average closing prices of the freely tradeable equity securities received for the 10 trading days ending on the date prior to such applicable date (the “Acquisition Option”). The Selling Parties shall have the right to exercise the Acquisition Option by written notice given to the Purchaser no later than the earlier of (i) 10 business days after the Purchaser gives written notice to the Selling Parties that it has received Company Consideration of at least $330 million in cash and (ii) 10 business days prior to the first anniversary of such transaction; provided that the Acquisition Option shall expire if not exercised by the applicable date, in which event any distribution of Company Consideration otherwise subject to this paragraph shall be governed by the first paragraph of this subsection (a) above and not this subsection (2). If the Selling Parties exercise the Acquisition Option and receive the payment therefore, then no further payment shall be due and payable in respect thereof pursuant to this Section 1.4.

The Purchaser shall pay any increase in the Purchase Price pursuant to this subsection promptly following notice of exercise of the IPO or Acquisition Option to the Selling Parties in the same form in which it is distributed to NPT LLC’s members

contemporaneous with the related distribution to its members; provided, that if the Selling Parties exercise the IPO Option or the Acquisition Option and the Company Consideration related thereto includes restricted or control stock, the Purchaser may, in its discretion, pay the increase in the purchase price related to the exercise of the applicable option in equity securities of the issuer, in which event it will use all reasonable efforts to negotiate to have the issuer provide the Selling Parties with customary demand and piggy back registration and indemnification rights relating thereto; provided further that if the issuer declines to provide the Selling Parties with such rights, the Purchaser will make arrangements to permit the Selling Parties to exercise piggy back registration rights with respect to any demand registration rights granted to the Purchaser.

(b) A “Credence Transaction” is a merger or acquisition of the Companies by Credence Systems Corp, or any subsidiary thereof or successor thereto (collectively, “Credence”) or the sale of all or substantially all of the Companies’ assets to Credence pursuant to a definitive agreement entered into within 180 days of the Closing Date pursuant to which NPT LLC receives Company Consideration in the aggregate of at least $227 million. For purposes of this paragraph, equity securities shall be valued based upon the average closing prices of the equity securities received for the 10 trading days ending two trading days prior to the closing of the transaction. In the event of a Credence Transaction, the Purchaser shall pay to the Selling Parties fifty percent (50%) of the difference, if any, between the value of the Credence Company Consideration and $227 million within five days following the closing date of the Credence Transaction. If the Company Consideration includes cash and equity securities, the cash portion shall be allocated to NPT LLC until NPT LLC has received up to a total of $227 million. The type of the remaining Company Consideration shall be allocated between NPT LLC and the Selling Parties in accordance with their pro rata entitlement thereto. NPT LLC will use all reasonable efforts to negotiate to have the issuer provide the Selling Parties with customary demand and piggy back registration and indemnification rights relating thereto; provided further that if the issuer declines to provide the Selling Parties with such rights, the Purchaser will make arrangements to permit the Selling Parties to exercise piggy back registration rights with respect to any demand registration rights granted to the Purchaser. Any transaction meeting the requirements of both paragraph (a)(2) and this paragraph (b) shall be governed solely by this paragraph (b). No further payment shall be due to the Selling Parties pursuant to this Section 1.4 upon payment in full of all amounts due pursuant to this paragraph (b).

(c) Any payments made to the Selling Parties pursuant to this section shall be paid in accordance with the pro rata shares of the Selling Parties of the purchase price as determined in accordance with Section 1.5 hereof.

(d) The parties will not, by manipulation of the sequence of events noted above, or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder, but will at all times in good faith reasonably assist in the carrying out of all the provisions of this Section 1.4 and in the taking of all such action as may be reasonably

necessary or appropriate in order to protect the rights of the parties pursuant to this Section 1.4.

(e) Purchaser and each Seller acknowledge and agree that, for U.S. Federal income tax purposes, (i) the fair market value of any amounts payable under this Section 1.4 are not reasonably ascertainable within the meaning of Treasury Regulation Section 1001-1(g)(2)(ii), and (ii) a portion of any such amount received by each Seller will consist of interest, calculated in accordance with the principles of Treasury Regulation 1.483-4(a).

(f) This Section 1.4 shall terminate at such time as all of the Company Consideration has been included and counted as Aggregate Distribution Value and the payment therefor, if any, has been fully paid to the Selling Parties. Notwithstanding anything to the contrary set forth above, in no event shall any Company Consideration be counted in a manner that requires a payment arising therefrom to the Selling Parties more than once.

Section 1.5 Allocation of the Purchase Price. Purchaser and Sellers agree that they shall complete Schedule 1.5 at Closing, which will set forth the allocation of the Initial Cash Consideration between each of STI and SBV in accordance with an appraisal by Standard & Poor’s (the “S&P Appraisal”) of the respective values of the NPT Shares and the BVI Shares (it being understood that such schedule will be arrived at by arm’s length negotiation). Any Purchase Price Adjustment received or paid by the Sellers shall be allocated between the Sellers in the manner agreed by the parties based on the facts available or, in the absence of any agreement, pro rata to the allocation of the Initial Cash Consideration set forth on Schedule 1.5. Purchaser and each Seller shall: (a) timely file all Tax Returns, if any, required to be filed in connection with such allocation; (b) be bound by such allocation for purposes of determining Taxes; (c) prepare and file its Tax Returns, if any, on a basis consistent with such allocation; and (d) take no position inconsistent with such allocation on any applicable Tax Return, in any audit or Proceeding before any Taxing Authority, in any report made for Tax, financial accounting or any other purposes, or otherwise. In the event that the allocation set forth in such schedule is disputed by any Taxing Authority, the party receiving notice of such dispute shall promptly notify the other party hereto concerning the existence and the resolution of such dispute.

REPRESENTATIONS AND WARRANTIES

OF THE SELLER PARTIES

Except as set forth in the Disclosure Schedule prepared and signed by each Seller Party and delivered to Purchaser simultaneously with the execution hereof, each Seller Party represents and warrants to Purchaser that all of the statements contained in this Article III are true as of the date of this Agreement (or, if made as of a specified date,

as of such date). For purposes of the representations and warranties of the Seller Parties contained herein, disclosure in any section of the Disclosure Schedule of any facts or circumstances shall be deemed to be adequate response and disclosure of such facts or circumstances with respect to all representations or warranties by the Seller Parties calling for disclosure of such information, whether or not such disclosure is specifically associated with or purports to respond to one or more or all of such representations or warranties if it is reasonably apparent on the face of the Disclosure Schedule that such disclosure is applicable. The inclusion of any information in any section of the Disclosure Schedule or other document delivered by the Seller Parties pursuant to this Agreement shall not be deemed to be an admission or evidence of the materiality of such item, nor shall it establish a standard of materiality for any purpose whatsoever.

Section 3.1 Organization. STI is a corporation duly organized, validly existing and in good standing under the laws of Delaware and has all requisite corporate or other power and authority and all necessary governmental approvals to own, lease and operate its properties and to carry on its business as now being conducted, except where the failure to be so organized, existing and in good standing or to have such power, authority, and governmental approvals would not have, individually or in the aggregate, a material adverse effect on STI’s ability to consummate the NPT Sale or any of the other Transactions it is obligated to carry out under this Agreement. SBV is a corporation duly organized under the laws of The Netherlands and has all requisite corporate or other power and authority and all necessary governmental approvals to own, lease and operate its properties and to carry on its business as now being conducted, except where the failure to be so organized, existing and in good standing or to have such power, authority, and governmental approvals would not have, individually or in the aggregate, a material adverse effect on SBV’s ability to consummate the BVI Sale or any of the other Transactions it is obligated to carry out under this Agreement. The Seller Parties have heretofore delivered to the Purchaser true and complete copies of the respective certificate of incorporation and bylaws, or equivalent governing instruments, of STI and STC as then currently in effect. Neither STI nor SBV are in violation of any of the provisions of their respective articles of incorporation or bylaws, or equivalent governing instruments.

Section 3.2 Authorization; Validity of Agreement. Each Seller Party has the requisite corporate power and authority to execute and deliver this Agreement and to carry out its obligations hereunder and, in the case of Sellers, to consummate the Transactions. The execution, delivery and performance by each Seller Party of this Agreement and, in the case of Sellers, the consummation of the Transactions, have been duly authorized by the board of directors or equivalent governing body of each Seller Party, or no such authorization is required, and no other corporate action on the part any of them is necessary to authorize the execution and delivery by them of this Agreement, the performance of their obligations hereunder or, in the case of the Sellers, the consummation of the Transactions. Other than such votes as have been obtained, no vote of, or consent by, the holders of any class or series of stock issued by any Selling Party is necessary to authorize the execution and delivery by them of this Agreement, the performance of their obligations hereunder or, in the case of the Sellers, the consummation by them of the Transactions.

Section 3.3 Execution; Validity of Agreement.

REPRESENTATIONS AND WARRANTIES

OF PURCHASER AND PARENT

Each of Purchaser and Parent represents and warrants to each Seller that:

Section 4.1 Organization. Purchaser is a corporation duly organized, validly existing and in good standing under the laws of Delaware and has all requisite corporate or other power and authority and all necessary governmental approvals to own, lease and operate its properties and to carry on its business as now being conducted, except where the failure to be so organized, existing and in good standing or to have such power, authority, and governmental approvals would not have, individually or in the aggregate, a material adverse effect on Purchaser’s ability to perform its obligations hereunder and consummate the Transactions.

Section 4.2 Authorization; Validity of Agreement. Each of Purchaser and Parent has full corporate power and authority to execute and deliver this Agreement and, in the case of Purchaser, to consummate the Transactions. The execution, delivery and performance by each of Purchaser and Parent of this Agreement, its performance of its obligations hereunder and the consummation of the Transactions have been duly authorized by the board of directors of Purchaser and Parent, and no other corporate action on the part of Purchaser or Parent is necessary to authorize the execution and delivery by each of Purchaser and Parent of this Agreement, the performance of its obligations hereunder, or the consummation of the Transactions.

Section 4.4 Acquisition of Shares for Investment; Ability to Evaluate and Bear Risk; Accredited Investor; Shares Not Registered.

(a) Purchaser is acquiring the NPT Shares and the BVI Shares for investment and not with a view toward, or for sale in connection with, any distribution thereof, or with any present intention of distributing or selling the NPT Shares or BVI Shares. Purchaser agrees that the NPT Shares and the BVI Shares may not be sold, transferred, offered for sale, pledged, hypothecated or otherwise disposed of without registration under the Securities Act and any applicable state or foreign securities laws, except pursuant to an exemption from such registration under such Act and such laws.

(b) Purchaser is able to bear the economic risk of holding the NPT Shares and the BVI Shares for an indefinite period, and has knowledge and experience in financial and business matters such that it is capable of evaluating the risks of the investment in the NPT Shares and the BVI Shares.

Section 4.5 Availability of Funds. Purchaser has previously delivered to Sellers a true and correct copy of the equity commitment letter from Francisco Partners, L.P. (the “Equity Commitment Letter”), which remains in full force and effect. Purchaser will at the Closing have sufficient immediately available funds, in cash, to pay the Purchase Price and to pay any other amounts payable pursuant to this Agreement and to effect the Transactions.

Section 4.6 Litigation. There is no claim, action, suit, proceeding or, to the knowledge of Purchaser or Parent, governmental investigation pending or, to the knowledge of Purchaser or Parent, threatened against Purchaser or Parent or any Parent Subsidiary by or before any court or Governmental Entity that, individually or in the aggregate, would have or would reasonably be expected to impede the ability of Purchaser to consummate the Transactions.

Section 4.7 Investigation by Purchaser; Sellers’ Liability. Purchaser has conducted its own independent investigation, review and analysis of the business, operations, assets, liabilities, results of operations, financial condition, software, technology and prospects of each Company, which investigation, review and analysis was done by Purchaser and, to the extent Purchaser deemed appropriate, by Purchaser’s or Parent’s representatives. Purchaser acknowledges that it and its representatives have been provided adequate access to the personnel, properties, premises and records of each Company for such purpose. In entering into this Agreement, Purchaser acknowledges that it has relied solely upon the aforementioned investigation, review and analysis and not on any factual representations or opinions of any Seller Party or its representatives (except the specific representations and warranties of the Seller Parties set forth in Article III of this Agreement and schedules thereto), and Purchaser and Parent each:

(a) acknowledges that no Seller Party, Company or any of their respective directors, officers, shareholders, employees, Affiliates, controlling persons, agents, advisors or representatives makes or has made any oral or written representation or warranty, either express or implied, as to the accuracy or completeness of any of the information (including in the descriptive memorandum relating to the Companies provided to the Purchaser and Parent, in materials furnished in the Companies’ data room, in presentations by the Seller Parties’ management or otherwise) provided or made available to either Purchaser or its directors, officers, employees, Affiliates, controlling persons, agents or representatives, and

(b) agrees, to the fullest extent permitted by law, that no Seller Party, Company or any of their respective directors, officers, employees, shareholders, Affiliates, controlling persons, agents, advisors or representatives shall have any liability or responsibility whatsoever to Purchaser or Parent any of their respective directors, officers, employees, Affiliates, controlling persons, agents or representatives on any basis (including in contract or tort, under federal or state securities laws or otherwise) based upon any information provided or made available, or statements made (including in the descriptive memorandum relating to the Companies provided to the Purchaser and Parent, in materials furnished in the Companies’ data room and in presentations by any of the Seller Parties’ management or otherwise), to Purchaser, Parent or any of their respective directors, officers, employees, Affiliates, controlling persons, advisors, agents or representatives (or any omissions therefrom), including in respect of the specific representations and warranties of the Seller Parties set forth in this Agreement, except that the foregoing limitations in subsections (a) and (b) above shall not apply to the Seller Parties insofar as the Seller Parties make the specific representations and warranties set forth in Article III of this Agreement, but always subject to the limitations and restrictions contained in Article VIII.

Section 4.8 Brokers or Finders. Neither Purchaser nor any of its Subsidiaries or its Affiliates has entered into any agreement or arrangement entitling any agent, broker, investment banker, financial advisor or other firm or Person to any broker’s or finder’s fee or any other commission or similar fee in connection with any of the Transactions that could give rise to any liability on the part of the Seller Parties.

ARTICLE V

COVENANTS

(a) the business of each Company shall be conducted in the same manner as heretofore conducted and only in the ordinary course consistent with past practices and, without limiting the foregoing, (i) each Company shall manage its working capital (including the timing of payment of accounts payable, collection of accounts receivable and the management of its inventory) in the ordinary course consistent with past practice and (ii) each Company shall continue to make capital expenditures consistent with the annual plan and in the ordinary course of business consistent with past practices;

(b) no Company shall: (i) amend its limited liability company agreement, certificate of incorporation, by-laws or similar organizational documents, (ii) issue, sell, transfer, pledge, dispose of or encumber any shares or interests of any class or series of its capital stock, or securities convertible into or exchangeable for, or options, warrants, calls, commitments or rights of any kind to acquire, any shares or interests of any class or series of its capital stock, (iii) except as set forth in Section 5.9, declare, set aside or pay any dividend or other distribution payable in cash, stock or property with respect to any shares of any class or series of its capital stock or any limited liability company interests, (iv) split, combine or reclassify any shares of any class or series of its stock or interests, or (v) redeem, purchase or otherwise acquire directly or indirectly any shares or interests of any class or series of its capital stock, any instrument or security which consists of or includes a right to acquire such shares or interest;

(d) no Company shall make any change in the compensation payable or to become payable to any of the Retained Employees (other than regularly scheduled increases to non-executive employees in the ordinary course of business consistent with past practice or as set forth in Section 3.14 of the Disclosure Schedule), or adopt, enter into or amend any Plan;

(g) no Company shall change in any material respect any of the accounting methods used by it unless required by GAAP;

(h) no Company shall take, or agree to or commit to take, any action that would result in any of the conditions to the Closing set forth in Article VI not being satisfied, or would make any representation or warranty of the Seller Parties contained herein inaccurate in any material respect at, or as of any time prior to, the Closing Date, or that would materially impair the ability of Purchaser or either Seller to consummate the Closing in accordance with the terms hereof or materially delay such consummation; and

(i) no Company shall enter into any agreement, contract, commitment or arrangement to do any of the foregoing.

Notwithstanding anything to the contrary contained herein, nothing shall prohibit NPT from sweeping cash from the accounts of the US Company and the US

Company Subsidiaries and SBV from sweeping cash from the accounts of BVI Company and the BVI Subsidiaries at any time prior to and including June 30, 2003. From June 30, 2003 through the Closing Date, Sellers and the Companies will operate the Companies for the benefit of Purchaser and with a view to preserving for Purchaser the benefits of the operations of the Companies, including any net income and cash flow realized during such period. In particular, during such period, none of the Companies shall, without the consent of Purchaser, repay any indebtedness of any Company to Sellers or any of their Affiliates or charge to any Company any consent fee to be paid in connection with the Transactions.

Section 5.2 Access; Confidentiality.

(a) STI shall cause the US Company and the US Company Subsidiaries and SBV shall cause the BVI Company and the BVI Subsidiaries prior to the Closing to (i) give Purchaser and each of its respective authorized representatives reasonable access to all books, records, personnel, offices and other facilities and properties of the Companies, (ii) permit Purchaser to make such copies and inspections thereof as Purchaser may reasonably request and (iii) cause the member or officers of each Company to furnish Purchaser with such financial and operating data and other information with respect to the business and properties of each Company as Purchaser may from time to time reasonably request; provided, however, that any such access shall be conducted at a reasonable time under the reasonable supervision of any of the personnel of the Seller Parties or the Companies and in such a manner as to maintain the confidentiality of this Agreement and the transactions contemplated hereby and not to interfere with the normal operation of the business of any Seller Party or Company. Notwithstanding anything contained in this or any other agreement between Purchaser, Parent and the Seller Parties executed prior to the date hereof, no Company, Seller Party or any Affiliate of the Seller Parties shall have any obligation to make available to Purchaser, Parent or any of their respective representatives, or provide Purchaser, Parent or any of their respective representatives with, any consolidated, combined or unitary Tax Return filed by any Seller Party or any of its Affiliates or predecessors, or any related material.

(b) The provisions of the Confidentiality Agreement shall remain binding and in full force and effect. The information contained herein, in the Disclosure Schedule or delivered to Purchaser or their respective authorized representatives pursuant hereto shall be deemed to be “Confidential Information” (as defined and subject to the exceptions contained in the Confidentiality Agreement) until the Closing. Except as otherwise provided in Section 5.5 or in this Section 5.2(b), each of Purchaser and Parent shall cause its consultants, advisors and representatives to treat the terms of this Agreement after the date hereof as strictly confidential (unless compelled to disclose by judicial or administrative process or, in the opinion of legal counsel, by other requirements of law). Notwithstanding the foregoing or any other provision of the Confidentiality Agreement, each of Parent, Purchaser and the Seller Parties shall be permitted to disclose the tax treatment and tax structure of the transaction (including any materials, opinions or analyses relating to such tax treatment or tax structure).

Section 5.3 Efforts and Actions to Cause Closing to Occur.

(a) Prior to the Closing, upon the terms and subject to the conditions of this Agreement, Purchaser, Parent and each Seller Party shall use all reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done and cooperate with each other in order to do, all things necessary, proper or advisable (subject to any applicable laws) to consummate the Closing and the other Transactions as promptly as practicable, including the preparation and filing of all forms, registrations and notices required to be filed to consummate the Closing and the other Transactions and the taking of such actions as are reasonably necessary to obtain any requisite approvals, authorizations, consents, orders, licenses, permits, qualifications, exemptions or waivers by any third party or Governmental Entity. In addition, no party hereto shall take any action after the date hereof that could reasonably be expected to materially delay the obtaining of, or result in not obtaining, any permission, approval or consent from any Governmental Entity or other Person required to be obtained prior to Closing. Nothing contained in this Agreement (except as provided in clause (d) below) shall require any Seller Party or Company to pay any material consideration to any other Person from whom any such approvals, authorizations, consents, orders, licenses, permits, qualifications, exemptions or waiver is requested.

(b) Prior to the Closing, each party shall promptly consult with the other party hereto with respect to, provide any necessary information with respect to, and provide the other parties (or their respective counsel) with copies of, all filings made by such party with any Governmental Entity or any other information supplied by such party to a Governmental Entity in connection with this Agreement and the Transactions. Each party hereto shall promptly inform the other of any communication received by such party from any Governmental Entity regarding any of the Transactions. If any party hereto or Affiliate thereof receives a request for information or documentary material from any such Governmental Entity with respect to any of the Transactions, then such party shall endeavor in good faith to make, or cause to be made, as soon as reasonably practicable and after consultation with the other parties, an appropriate response in compliance with such request.

(c) In addition to and without limiting the agreements of the parties contained above, Purchaser, Parent and each Seller Party shall (i) take promptly all actions necessary to make the filings required of them or any of their Affiliates under the HSR Act, (ii) comply at the earliest practicable date with any request for additional information or documentary material received by Purchaser, any Seller, any Company or any of their respective Affiliates from the FTC or the DOJ pursuant to the HSR Act or from any state Attorney General or other Governmental Entity in connection with antitrust matters, (iii) cooperate with each other in connection with any filing under the HSR Act and in connection with resolving any investigation or other inquiry concerning the Transactions commenced by the FTC, DOJ, any state Attorney General or any other Governmental Entity, (iv) use all reasonable efforts to resolve such objections, if any, as may be asserted with respect to the Transactions under any antitrust law and (v) advise the other parties promptly of any material communication received by such party from the FTC, DOJ, any state Attorney General or any other Governmental Entity regarding

any of the Transactions, and of any understandings, undertakings or agreements (oral or written) such party proposes to make or enter into with the FTC, DOJ, any state Attorney General or any other Governmental Entity in connection with the Transactions. Concurrently with the filing of notifications under the HSR Act or as soon thereafter as practicable, each Seller and Purchaser shall each request early termination of the HSR Act waiting period. Notwithstanding the foregoing with regard to Purchaser, “all reasonable efforts” for purposes of Section 5.3(c)(iv) shall not require acceptance of any order providing for the divestiture by Purchaser of such properties, assets, operations, or businesses of Purchaser or any Seller or the holding separate of such properties, assets, operations or businesses pending any such divestiture.

(d) The Seller Parties shall use their commercially reasonable efforts to assign all licenses set forth on Schedule 5.3(d) to the Companies, and any costs associated with such assignments exceeding $25,000 in the aggregate shall be at Seller Parties’ expense; provided that if the Seller Parties do not obtain such assignment of any such license within five (5) days prior to the Closing Date, Seller Parties at their expense shall purchase new licenses for the benefit of the Companies or shall indemnify Purchaser for any losses arising therefrom on substantially the same terms as currently licensed; and provided further, that if this Agreement is terminated due to a willful or intentional breach by Parent or Purchaser, Purchaser and Parent shall be responsible for the costs and expenses incurred by the Seller Parties under this Section 5.3(d).

Section 5.4 Tax Matters.

(a) Section 338(h)(10) Election

(i) Upon the request of Purchaser, Purchaser and STI shall jointly make a timely, effective and irrevocable election under Section 338(h)(10) of the Code with respect to the US Company and the US Company Subsidiaries, and, if permissible, similar elections under any applicable state or local income tax laws (the “Elections”), and shall file the Elections in accordance with applicable regulations. Any such request shall be made by Purchaser in writing within 180 days following the Closing Date. In the event Purchaser does not request that STI join in making the Elections, the remainder of the provisions of this Section 5.4(a) shall not apply.

(ii) Purchaser, STI and the US Company shall report the transaction consistent with such Elections and agree not to take any action that could cause such Elections to be invalid, and shall take no position contrary thereto unless required to do so pursuant to a determination (as defined in Section 1313(a) of the Code) or any similar state or local Tax provision.

(iii) In connection with the Elections, Purchaser and STI shall mutually prepare any and all forms necessary to effectuate the Elections (including, without limitation, IRS Form 8023 and any

similar forms under applicable state and local income tax laws (the “Section 338 Forms”)). Purchaser and STI shall each cause the Section 338 Forms to be duly executed by an authorized person, and shall duly and timely file the Section 338 Forms in accordance with applicable tax laws.

(iv) In connection with the Elections, STI and Purchaser shall act together in good faith to prepare a schedule setting forth the fair market value of the assets of the US Company and the allocation of the aggregate deemed sales price (as defined under Section 1.338-4 of the Treasury Regulations) among the assets of the US Company resulting from the elections under Section 338(h)(10) of the Code (as required pursuant to Section 338(h)(10) of the Code and the Treasury Regulations promulgated thereunder) (the “Section 338 Allocation”). The Section 338 Allocation shall be prepared in accordance with the rules under Sections 1060 and 338 of the Code, as applicable. If the Sellers and Purchaser are unable to agree on the Section 338 Allocation by the 210th day following the Closing, they shall request a nationally recognized accounting firm, which is mutually acceptable to STI and Purchaser, to prepare such Section 338 Allocation. The cost of any such firm shall be borne equally by Purchaser and STI. Purchaser and STI shall (A) be bound by the Section 338 Allocation for purposes of determining any Taxes, (B) prepare and file, and cause its Affiliates to prepare and file, its Tax Returns on a basis consistent with Section 338 Allocation, and (C) take no position, and cause its Affiliates to take no position, inconsistent with the Section 338 Allocation on any Tax Return, in any refund claim, in any audit, dispute or proceeding before any Taxing Authority or otherwise with respect to such Tax Returns. In the event the Section 338 Allocation is audited or disputed by any Taxing Authority, the party receiving notice thereof shall promptly notify the other party hereto.

(b) Tax Returns. Except as provided in Section 5.4(d) or (e),

(i) Each Seller shall file or cause to be filed when due all income and franchise Tax Returns that are required to be filed by or with respect to each Company for taxable years or periods ending on or before the Closing Date, such Tax Returns, as of the time of filing, shall be correct and complete in all material respects, and each Seller shall remit (or cause to be remitted) subject to Section 5.4(c)(ii) and Section 8.1(b) any Taxes due in respect of such Tax Returns.

(ii) Purchaser shall cause each Company to file or cause to be filed all Tax Returns other than income and franchise Tax Returns that are required to be filed by or with respect to any Company for taxable years or periods ending on or before the Closing Date. Any Tax Returns which the Purchaser is required to cause the Company to file or cause to be filed pursuant to this Section 5.4(b)(ii) shall be completed in a manner consistent with past practice and shall be submitted (with copies

of any relevant schedules, work papers and other documentation then available) to Sellers for Sellers’ approval not less than 30 days prior to the Due Date for the filing of such Tax Return, which approval may not be unreasonably withheld. Purchaser shall remit (or cause to be remitted) any Taxes due in respect of such Tax Returns, subject to Section 5.4(b)(v).

(iii) Purchaser shall file or cause to be filed when due all Tax Returns that are required to be filed by or with respect to each Company for taxable years or periods ending after the Closing Date, and Purchaser shall remit (or cause to be remitted) any Taxes due in respect of such Tax Returns, subject to Section 5.4(b)(v).

(iv) Any Tax Return required to be filed by Purchaser relating to any Straddle Period shall be submitted (with copies of any relevant schedules, work papers and other documentation then available) to Sellers for Sellers’ approval not less than 60 days prior to the Due Date for the filing of such Tax Return, which approval shall not be unreasonably withheld. Purchaser shall, in preparing such Tax Return, cause the items to be reflected in accordance with the Sellers’ past practice, if any, to the extent permissible under applicable law.

(v) Upon the written request of Purchaser setting forth in detail the computation of the amount owed, the Sellers shall pay to Purchaser, no later than 2 days prior to the Due Date for the applicable Tax Return, the Taxes for which each Seller is liable pursuant to Section 8.1(b)(ii) but which are payable with any Tax Return to be filed by Purchaser.

(vi) As soon as practicable after the Closing Date or sooner if reasonably required by the Sellers to timely file any Tax Return required to be filed or caused to be filed by it pursuant to the terms of this Agreement, Purchaser shall cause each Company to prepare and provide to the Sellers a package of Tax information materials, including schedules and work papers required by the Sellers to enable the Sellers to prepare and file all Tax Returns required to be prepared and filed by them pursuant to Section 5.4(b)(i). Purchaser shall prepare such package in good faith in a manner consistent with the Sellers’ past practice. In furtherance of this obligation, Purchaser agrees that, at Sellers’ request, each Company will make its employees and facilities available to Sellers to the extent necessary, convenient or desirable in order to prepare and complete any such Tax Return.

(vii) The Sellers may amend any Tax Return filed or required to be filed for any taxable years or periods ending on or before the Closing Date to the extent necessary to correct any manifest errors on such Tax Return, provided that, unless the filing of such Tax Return is manifestly required by law, such action would not have the effect of

materially increasing the Tax liability or materially reducing any Tax Asset (or the tax basis in the inventory) of any Company, Purchaser or any Affiliate of Purchaser.

(c) Computation of Tax Liabilities. For purposes of Sections 5.4(b), 8.1(b) and 8.1(c), to the extent permitted or required by law or administrative practice, (A) the taxable year of Companies which includes the Closing Date shall be treated as closing on (and including) the Closing Date and, notwithstanding the foregoing, (B) all transactions not in the ordinary course of business occurring after the Closing shall be reported on Purchaser’s consolidated United States federal income Tax Return to the extent permitted by Treasury Regulation Section 1.1502-76(b)(1)(ii)(B) and shall be similarly reported on other Tax Returns of Purchaser or its Affiliates to the extent permitted by law. For purposes of Sections 5.4(b), 8.1(b) and 8.1(c), where it is necessary to apportion the Tax liability of an entity for a Straddle Period (which is not treated under the immediately preceding sentence as closing on the Closing Date), such liability shall be apportioned between the period deemed to end at the close of the Closing Date and the period deemed to begin at the beginning of the day following the Closing Date on the basis of an interim closing of the books, except that Taxes (such as real property Taxes) imposed on a periodic basis shall be allocated on a daily basis and the principles of Treasury Regulation Section 1.1502-76(b)(1)(ii)(B) shall be applied with respect to all transactions not in the ordinary course of business occurring after the Closing.

(ii) In determining the Sellers’ liability for Taxes pursuant to this Agreement, each Seller shall be credited with the amount of any estimated Taxes paid (A) by or on behalf of the Company on or prior to the Closing Date with respect to Straddle Periods or (B) by Sellers after the Closing Date. To the extent that any Seller’s liability for Taxes for a Straddle Period is less than the amount of estimated Taxes previously paid (A) by or on behalf of any Company on or prior to the Closing Date or (B) by Sellers after the Closing Date, in each case with respect to all or a portion of such Straddle Period, Purchaser shall pay such Sellers the difference within two days of filing the Tax Return relating to such Taxes.

(d) Transfer Taxes. All Transfer Taxes resulting directly from the Transactions shall be borne equally by Purchaser and the Sellers; provided, however, that to the extent any Transfer Tax arises as a result of the Purchaser making an election under Section 338 of the Code or the Elections such Transfer Tax shall be borne by Purchaser. Notwithstanding the provisions of Section 5.4(b), which shall not apply to Tax Returns relating to Transfer Taxes, any Tax Returns that must be filed in connection with Transfer Taxes shall be prepared and filed when due by the party primarily or customarily responsible under the applicable local law for filing such Tax Returns, and such party will use its reasonable efforts to provide such Tax Returns to the other party at least 10 days prior to the Due Date for such Tax Returns. If required by applicable law,

Purchaser will, and will cause its Affiliates to, join in the execution of any such Tax Returns.

(e) Actions by the Sellers and Companies.

(i) Without the prior written consent of Purchaser, which consent shall not be unreasonably withheld, none of Sellers, the Companies, and any Affiliate of Sellers shall, to the extent it may affect or relate to any Company, make or change any Tax election, change any annual Tax accounting period, adopt or change any method of Tax accounting, enter into any closing agreement, settle any Tax claim or assessment, surrender any right to claim a Tax refund, offset or other reduction in Tax liability, consent to any extension or waiver of the limitations period applicable to any Tax claim or assessment or take or omit to take any other action, if any such action or omission would have the effect of materially increasing the Tax liability or materially reducing any Tax Asset of any Company, Purchaser or any Affiliate of Purchaser.

(ii) Prior to the Closing, none of the Companies shall make any payment of, or in respect of, any Tax to any person or any Taxing Authority, except to the extent such payment is in respect of a Tax that is due or payable or has been properly estimated in accordance with applicable law as applied in a manner consistent with past practice of Sellers.

(iii) Sellers shall not take any action (other than sales or other dispositions in the ordinary course of business) that would result in the reduction of the tax basis in the inventory of any Company below the tax basis in such inventory reflected on the Balance Sheet.

(f) Refunds.

(i) If Purchaser or any Company receives or becomes entitled to any Tax refund (including any interest in respect thereof), including by way of any amended Tax Returns or any carry back filing, that relates to any taxable period, or portion thereof, ending on or before the Closing Date, Purchaser shall pay Sellers the amount of any such refund net of any Tax effect on Purchaser or any Company attributable to the receipt of such refund within five days after receipt of such refund. Purchaser and each Company shall make every effort to elect to receive a Tax refund described in the preceding sentence rather than a credit against a Tax. For purposes of this Section 5.4(f), where it is necessary to apportion a refund between Purchaser and any Seller for a Straddle Period, such refund shall be apportioned between the period deemed to end at the close of the Closing Date and the period deemed to begin at the beginning of the day following the Closing Date on the basis of an interim closing of the Companies’ books, except that refunds of

Taxes (e.g., real property Taxes) imposed on a periodic basis shall be allocated on a daily basis.

(ii) Purchaser shall cooperate, and cause the Company to cooperate, in obtaining any Tax refund that any Seller reasonably believes should be available, including through filing appropriate forms with the applicable Taxing Authorities, unless Purchaser reasonably believes that such a filing would have a material adverse effect on the Tax liability of Purchaser, any Company or any Affiliate of Purchaser or any Company.

(g) Certain Post-Closing Settlement Payments.

(i) If the examination of any federal, state, local or other Tax Return of either Seller for any taxable period ending on or before the Closing Date shall result (by settlement or otherwise) in any adjustment which permits Purchaser or any Company to increase deductions, losses or tax credits or decrease the income, gains or recapture of tax credits (a “Tax Benefit”) which would otherwise (but for such adjustments) have been reported or taken into account (including by way of any increase in basis) by Purchaser or such Company for one or more periods ending after the Closing Date, the Sellers shall notify Purchaser and provide it with adequate information so that Purchaser can reflect on its or the Company’s Tax Returns such Tax Benefit. Purchaser shall pay to the Sellers an amount equal to the actual Tax savings produced by such Tax Benefit within thirty (30) days of the filing of the Tax Returns for the taxable year in which such Tax savings is realized by Purchaser or the Company.

(ii) If the examination of any federal, state, local or other Tax Return of Purchaser or any Company for any taxable period ending after the Closing Date shall result (by settlement or otherwise) in any adjustment which permits either Seller to increase deductions, losses or tax credits or decrease the income, gains or recapture of tax credits which would otherwise (but for such adjustments) have been reported or taken into account (including by way of any increase in basis) by any Seller for one or more periods ending on or before the Closing Date, Purchaser shall notify Sellers and provide them with adequate information so that Sellers can reflect on their Tax Returns such increases in deductions, losses or tax credits or decreases in income, gains or recapture of tax credits.

(i) Without the prior written consent of the Sellers, which consent shall not be unreasonably withheld, none of

Purchaser, the Companies, and any Purchaser Affiliate shall, to the extent it may affect or relate to any Company, make or change any Tax election, change any annual Tax accounting period, adopt or change any method of Tax accounting, enter into any closing agreement, settle any Tax claim or assessment, surrender any right to claim a Tax refund, offset or other reduction in Tax liability, consent to any extension or waiver of the limitations period applicable to any Tax claim or assessment or take or omit to take any other action, if any such action or omission would have the effect of materially increasing the Tax liability of the Sellers (including any liability of the Sellers to indemnify the Purchaser for Taxes pursuant to this Agreement).

(ii) None of Purchaser or any Affiliate of Purchaser shall (or shall cause or permit any Company to) amend, refile or otherwise modify any Tax Return relating in whole or in part to the Company with respect to any taxable year or period ending on or before the Closing Date (or with respect to any Straddle Period) without the prior written consent of the Sellers, which consent may be withheld in the sole discretion of the Sellers; provided that the Sellers’ consent shall not be unreasonably withheld for modifications that relate to a Straddle Period.

(iii) To the extent permitted by law, Purchaser and any Affiliate of Purchaser shall (or shall cause or permit the Company to) elect to relinquish any carrybacks for Federal, state, local or foreign tax purposes to any taxable period, or portion thereof, of any Company or Seller or any Affiliate of Sellers ending before, or which includes, the Closing Date of any operating losses, net operating losses, capital losses, tax credits or similar items arising in, resulting from, or generated in connection with a taxable year of Purchaser or any Affiliate of Purchaser, or portion thereof, ending on or after the Closing Date. In cases where any Company cannot elect to relinquish the carrybacks, Sellers shall cooperate with Purchaser in seeking refunds from the appropriate Taxing Authority, at Purchaser’s expense, and the Companies shall be entitled to such refund to the extent it is received, including interest paid by the Taxing Authority in connection with such refund, in each case net of any tax imposed in respect of such refund or interest, within 5 days of Sellers’ receipt of such refund; provided, however, that (A) in the case of any carryback to a consolidated, combined, or unitary return of Sellers or their Affiliates, any carrybacks by Sellers and their Affiliates shall be deemed to be absorbed before any carryback of a Company, and (B) if the amount of a refund received from a Taxing Authority is reduced, whether by Audits or court proceedings or for any other reason, after the refund has been paid by Sellers to a Company, the Company will promptly reimburse the Sellers for the amount of such reduction plus any interest and penalties actually payable by the Sellers with respect thereto.

Section 5.5 Publicity. The initial press release with respect to the execution of this Agreement shall be a joint press release acceptable to Parent and each Seller.

Such service also shall apply for purposes of satisfying any waiting periods, evidence of insurability requirements, or the application of any preexisting condition limitations. Retained Employees shall be given credit for amounts paid under a corresponding employee benefit plan during the same period for purposes of applying deductibles, co-payments and out-of-pocket maximums as though such amounts had been paid in accordance with the terms and conditions of the comparable employee benefit plan of the Purchaser.

(c) If any Retained Employee is discharged by any Company after the Closing, then Purchaser shall be responsible for any and all severance costs for such Retained Employee, including payments owing under those agreements, plans or arrangements listed in the Disclosure Schedule.

(a) Each Seller Party shall indemnify, defend and hold harmless the Purchaser (and, effective as of the Closing Date, each Company) from and against and in respect of all Purchaser Losses.

(b) Each Seller Party shall severally indemnify and hold Purchaser (and, effective as of the Closing Date, each Company) harmless from and against the following:

(i) any liability for Taxes imposed on any Company as members of the “affiliated group” (within the meaning of Section 1504(a) of the Code) of which the Seller Party or any Affiliate of the Seller Party (or any predecessor or successor) is the common parent that arises under Treasury Regulation Section 1.1502-6(a) or comparable provisions of foreign, state or local law;

(ii) any liability for Taxes imposed on any Company, or for which any Company may otherwise be liable, for any taxable year or period that ends on or before the Closing Date and, with respect to any Straddle Period, the portion of such Straddle Period deemed to end on and include the Closing Date;

(iii) any liability for Taxes imposed on Purchaser, any Company, or any affiliate of Purchaser resulting from a breach of the provisions of Section 3.26 or Section 5.4;

(iv) any liability of any Company for the payment of any amount (A) as a result of being party to any tax sharing agreement entered into on or before the Closing Date or (B) with respect to the payment of any Taxes imposed on any person as a result of any existing express or implied agreement or arrangement entered into on or before the Closing Date (including, but not limited to, an indemnification agreement or arrangement); and

(v) all claims or liabilities arising from changes made to the compensation or benefits of employees of the Companies during the 12 months prior to the Closing;

provided, however, that no Seller Party shall be liable for and shall not indemnify Purchaser (or its Subsidiaries and Affiliates) for Excluded Taxes.

(i) Taxes imposed on any Company for any taxable year or period that begins after the Closing Date and, with respect

to any Straddle Period, the portion of such Straddle Period beginning after the Closing Date; and

(ii) Excluded Taxes.

(d) If an indemnification obligation under Section 8.1(b) or (c) arises in respect of an adjustment which makes allowable to the indemnitee any Tax Benefit which would not, but for such adjustment, be allowable, then the indemnitee shall pay to the indemnitor an amount equal to the actual Tax savings produced by such Tax Benefit at the time such Tax savings is realized by such indemnitee; provided, however, that the amount of any such payment to the indemnitor shall not exceed the amount of any indemnity payment made by such indemnitor with respect to the adjustment giving rise to the Tax Benefit. The amount of any such Tax saving for any Tax period shall be the amount of the reduction in Taxes payable to a Taxing Authority with respect to such Tax period as compared to the Taxes that would have been payable to a Taxing Authority by the indemnitee in the absence of such Tax Benefit, taking into account the effect, if any, of the receipt of the indemnity payment on the purchase price of any assets.

(e) Each Seller Party’s indemnification obligations under Sections 8.1(a) and 8.1(b) shall be subject to each of the following limitations:

(i) Each Seller Party’s indemnification obligations relating to Purchaser Losses under Section 8.1(a) shall survive only until the first anniversary of the Closing Date; provided, however, that:

(A) each Seller Party’s indemnification obligations with respect to the representations set forth in Section 3.23 shall survive until the third anniversary of the Closing Date; and

(B) each Seller Party’s indemnification obligations (I) with respect to the representations set forth in Sections 3.1 through 3.3, 3.5 through 3.8 and (II) for Tax Claims under Section 8.1(b), shall in each case survive for full period of the applicable statute of limitations (giving effect to any waiver, mitigation or extension thereof) (each such period, a “Survival Period”).

(ii) No claim for the recovery of any Purchaser Losses or Tax Claims may be asserted by any Purchaser Indemnified Person after the expiration of the relevant Survival Period; provided, however, that claims first asserted in writing by any Purchaser Indemnified Person with reasonable specificity prior to the expiration of the Survival Period shall not thereafter be barred by the expiration of the Survival Period. Except as otherwise provided herein, the parties intend to shorten the statute of limitations and agree that no claims or causes of action may be brought against any Seller Party based upon, directly or indirectly, any of the representations, warranties or agreements contained

in Article III after the relevant Survival Period or, except as provided in Section 7.2, any termination of this Agreement. This Section 8.1 shall not limit any covenant or agreement of the parties that contemplates performance after the Closing.

(iii) No reimbursement for Purchaser Losses asserted under Section 8.1(a) that is based upon any breach of any representation or warranty or any breach of any covenant which is not a willful and intentional breach, shall be required unless the aggregate amount of Purchaser Losses exceeds the Threshold, and, in such event, indemnification shall be made by the Seller Parties only to the extent Purchaser Losses exceed the Threshold. Purchaser shall not have the right to indemnification for any individual Purchaser Loss asserted under Section 8.1(a) that is based upon any breach of any representation or warranty or any breach of any covenant which is not a willful and intentional breach or any individual Tax Claim asserted under Section 8.1(b), which is equal to or less than $50,000, and any such individual Purchaser Losses which are equal to or less than such amount shall not be counted for purposes of determining whether the aggregate amount of Purchaser Losses exceeds the Threshold. The limitations set forth in this clause (iii) shall not apply to a material breach of Section 3.27(a)(iii) or Section 5.13(d) or to the obligations of the Seller Parties pursuant to Section 5.3(d).

(iv) Each Purchaser Loss shall be reduced by (1) the amount of any insurance proceeds actually recovered by Purchaser or any Purchaser Indemnified Person with respect to such loss, (2) any indemnity, contribution or other similar payment actually recovered by Purchaser or any Purchaser Indemnified Person by any third party with respect to such loss and (3) an amount equal to any reduction of income Taxes attributable to such loss.

(v) In no event shall any Seller Party’s aggregate liability to Purchaser under this Agreement for Purchaser Losses and breaches of representations or warranties, covenants or agreements, whether pursuant to this Article VIII or otherwise, other than Tax Claims asserted under Section 8.1(b), exceed $33,000,000 (the “Cap Amount”); provided, however, that for purposes of the foregoing allocations, the amount of any Purchaser Losses where it is not reasonably ascertainable whether the Purchaser Losses arose with respect to a particular Company or Companies and the parties cannot agree in good faith to the allocation of a Purchaser Loss to a particular Company or Companies, the Purchaser Loss shall be allocated between the Sellers pro rata to the allocations of the Initial Cash Consideration set forth in Schedule 1.5.

Section 8.2 Notice of Claim; Defense.

(a) Purchaser shall give each Seller Party prompt notice of any third-party claim (other than claims arising out of any pending or threatened audit, notice of deficiency, proposed adjustment, assessment, examination or other administrative or court proceeding, suit, dispute or other claim which could affect the liability for Taxes of any Seller Party or Seller Party Affiliate) that may give rise to any indemnification obligation under this Article VIII, together with the estimated amount of such claim, and any Seller Party or the Seller Parties shall have the right to assume the defense (at the Seller Parties’ expense) of any such claim through counsel of the Seller Party’s or Seller Parties’ own choosing by so notifying Purchaser within 30 days of the receipt by each Seller Party of such notice from Purchaser; provided, however, that (i) any such counsel shall be reasonably satisfactory to Purchaser; and (ii) failure to give such notice shall not affect the indemnification obligations set forth herein unless the Seller Parties are materially prejudiced by such failure. The Seller Parties shall be liable for the fees and expenses of counsel employed by Purchaser for any period during which no Seller Party has assumed the defense of any such third-party claim (other than during any period in which Purchaser will have failed to give notice of the third-party claim as provided above). If any Seller Party or the Seller Parties assume such defense, Purchaser shall have the right to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by any Seller Party or the Seller Parties; provided, however, that if Purchaser shall have reasonably concluded that a conflict may arise between the positions of the Seller or Seller Parties and Purchaser in conducting the defense of such action, the Purchaser shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of the Purchaser, and such Seller or Seller Parties shall be liable for any fees or expenses incurred thereby. If a Seller Party chooses or the Seller Parties choose to defend or prosecute a third-party claim, Purchaser shall cooperate in the defense or prosecution thereof, which cooperation shall include, to the extent reasonably requested by the Seller Party or the Seller Parties, the retention, and the provision to the Seller Party or Seller Parties, of records and information reasonably relevant to such third-party claim, and making employees of each Company available on a mutually convenient basis to provide additional information and explanation of any materials provided hereunder, but in each case at the expense of Seller or the Seller Parties. If any Seller Party chooses or the Seller Parties choose to defend or prosecute any third-party claim, Purchaser shall agree to any settlement, compromise or discharge of such third-party claim that Seller may recommend and that, by its terms, discharges Purchaser from the full amount of liability in connection with such third-party claim. None of Purchaser, any of its Affiliates or any Company may settle or otherwise dispose of any Claim for which the Seller Parties may have a liability under this Agreement without the prior written consent of each Seller Party, which consent shall not be unreasonably withheld by each Seller Party, unless Purchaser fully indemnifies each Seller Party in writing with respect to such liability in a manner reasonably satisfactory to each Seller Party. No Seller Party shall not be liable under this Section 8.2(a) for any settlement, compromise or discharge effected without its consent in respect of any claim for which indemnity may be sought hereunder. No indemnified party shall take any action the purpose of which is to prejudice the defense of any claim subject to indemnification hereunder or to induce a third party to assert a claim subject to indemnification hereunder.

(b) Each party hereto shall notify the chief tax officer of the other party in writing within 15 days following receipt by such party of written notice of any pending or threatened audits, notice of deficiency, proposed adjustment, assessment, examination or other administrative or court proceeding, suit, dispute or other claim which could affect the liability for Taxes of such other party. If the party required to give such notice fails to give such notice to the other party promptly, it shall not be entitled to indemnification for any Taxes arising in connection with such Tax Claim if and to the extent that such failure to give notice materially and adversely affects the other party’s right to participate in or defend the Tax Claim.

(c) The Seller Parties and their Affiliates shall have the sole right to represent the Company’s interests in any Tax Claim relating to taxable periods ending on or before the Closing Date and to employ counsel of its choice at its expense; provided that (i) the Seller Parties shall consult with Purchaser upon Purchaser’s reasonable request for such consultation from time to time with respect to such Tax Claim; and (ii) any settlement by the Seller Parties with respect to any Tax shall be subject to Section 5.4(e)(i). In the case of a Straddle Period, the Seller Parties and their Affiliates shall be entitled to participate at its expense in any Tax Claim relating in any part to Taxes attributable to the portion of such Straddle Period deemed to end on or before the Closing Date and, with the written consent of Purchaser, at the Seller Parties’ sole expense, may assume the control of such Tax Claim; provided that if Seller assumes the control of such Tax Claim, (i) the Seller Parties shall thereafter consult with Purchaser upon Purchaser’s reasonable request for such consultation from time to time with respect to such Tax Claim; and (ii) any settlement by the Seller Parties with respect to any Tax shall be subject to Section 5.4(e)(i). None of Purchaser, any of its Affiliates or the Company may settle or otherwise dispose of any Tax Claim for which the Seller Parties may have a liability under this Agreement without the prior written consent of each Seller Party, which consent may be withheld in the sole discretion of each Seller Party, unless Purchaser fully indemnifies each Seller Party in writing with respect to such liability in a manner satisfactory to each Seller Party.

Section 8.3 Resolution of All Tax-Related Disputes. If the Seller Parties and Purchaser cannot agree on the calculation of any amount relating to Taxes or the interpretation or application of any provision of this Agreement relating to Taxes, such dispute shall be resolved by a nationally recognized accounting firm mutually acceptable to each of the Seller Parties and Purchaser, whose decision shall be final and binding upon all persons involved and whose expenses shall be shared equally by the Seller Parties and Purchaser.

Section 8.4 Tax Effect of Indemnification Payments. All indemnity payments made by the Seller Parties to Purchaser Indemnified Persons, or by Purchaser Indemnified Persons to Seller, pursuant to this Agreement shall be treated for all Tax purposes as adjustments to the Purchase Price paid with respect to the NPT Shares and the BVI Shares.

Section 8.5 No Duplication; Sole Remedy Procedures.

(a) Any liability for indemnification hereunder shall be determined without duplication of recovery by reason of the state of facts giving rise to such liability constituting a breach of more than one representation, warranty, covenant or agreement.

(b) Purchaser’s rights to indemnification as provided for in Section 8.1 for a breach of the Seller Parties’ representations or warranties contained in this Agreement or a willful and intentional breach prior to the Closing by any Seller Party of the covenants contained in this Agreement shall constitute the sole remedy of any of Purchaser, Parent or any other Purchaser Indemnified Person for such a breach, and no Seller Party shall have any other liability or damages to Purchaser resulting from the breach.

(c) The indemnification and other provisions of this Article VIII shall govern the procedure for all indemnification matters under this Agreement, except to the extent otherwise expressly provided herein.

Section 8.6 No Right of Off-set/Set-off. Neither Purchaser nor any Seller Party shall have any right to off-set or set-off any payment due pursuant to Section 1.2 of this Agreement against any other payment to be made pursuant to this Agreement or otherwise (including against indemnification payments).

Section 10.5 Entire Agreement; No Third Party Beneficiaries. This Agreement, the License Agreement, the Transition Services Agreement and the Confidentiality Agreement (a) constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof and thereof and (b) are not intended to confer upon any Person other than the parties hereto and thereto and the officers and directors of the Seller Parties and the Retained Employees any rights or remedies hereunder.
