Section 2.02

Purchase Price.

(a) Subject to the terms and conditions of this Agreement, in reliance upon the representations, warranties and covenants of Target, Seller and Guarantor herein set forth, and as consideration for the purchase and sale of the Shares, Purchaser shall pay Seller by wire transfer of immediately available funds to the account(s) designated by the Seller, on the dates set forth below, the following sums (the “Purchase Price”):

(i) On the Closing Date, Forty Million Two Hundred and Fifty Thousand Dollars ($40,250,000) in cash. Of this amount, $4,000,000 (the “Escrow Amount”) shall be wired to a separate escrow account (the “Escrow Account”). The Escrow Amount shall be held in escrow for a period of fifteen (15) months following the Closing Date as security for the indemnification obligations of the Seller and Guarantor set forth in this Agreement. The Escrow Amount shall be governed by the terms and conditions of an Escrow Agreement by and among Seller, Purchaser and Wells Fargo, (the “Escrow Agent”) in the form attached hereto as Exhibit A;

(ii) the amount, if any, determined pursuant to Section 2.02(c) below within the time frame set therein; and

(b) Within 30 days after the Closing Date, the Seller shall have prepared and delivered to the Purchaser the Closing Financial Statements. Seller shall also deliver to the Purchaser a certificate containing Seller’s calculations, based on the Closing Balance Sheet contained in the Closing Financial Statements, of the Net Working Capital of the Target as of the Closing Date (the “Closing Date Net Working Capital”). The Closing Financial Statements and the calculation of the Closing Date Net Working Capital shall be final and binding on the parties unless, within 45 days after delivery to the Purchaser, the Purchaser shall deliver to the Seller a notice of dispute (a “Dispute Notice”), specifying in reasonable detail the items in dispute. After delivery of a Dispute Notice, Seller and the Purchaser shall promptly negotiate in good faith with respect to the subject of the Dispute Notice, and if they are unable to reach an agreement within 15 days after delivery to the Seller of the Dispute Notice, the dispute shall be submitted to PricewaterhouseCoopers, or such other independent public accounting firm as mutually agreed to by the Purchaser and the Seller (the “Independent Accounting Firm”). The Independent Accounting Firm shall be directed to issue a final and binding decision within 45 days of submission of the Dispute Notice to the Independent Accounting Firm, as to the issues of disagreement referred to in the Dispute Notice and not resolved by the Purchaser and the Seller. Each of the parties hereto agrees that it shall be bound by the determination of the Independent Accounting Firm. The fees, costs and expenses of the Independent Accounting Firm shall be allocated to and borne by Purchaser and Seller based on the inverse of the percentage that the Independent Accounting Firm’s determination (before such allocation) bears to the total amount of the total line items in dispute as originally submitted to the Independent Accounting Firm. For example, should the items in dispute total in amount to $1,000 and the Independent Accounting Firm awards $600 in favor of the Seller’s position, 60% of the costs of its review would be borne by the Purchaser and 40% of the costs would be borne by the Seller.

(c) If the Closing Date Net Working Capital, as determined in accordance with Section 2.02(b) above is less than $5,650,000 million (the “Target Net Working Capital Level”), the Purchase Price shall be reduced, dollar-for-dollar, by the amount by which the Target Net Working Capital Level exceeds the Closing Date Net Working Capital, and the Seller shall pay the Purchaser the dollar amount by which the Target Net Working Capital

Level exceeds the Closing Date Net Working Capital. If the Closing Date Net Working Capital is greater than the Target Net Working Capital Level, then the Purchase Price shall be increased, dollar-for-dollar, by the amount the Closing Date Net Working Capital exceeds the Target Net Working Capital Level, and the Purchaser shall pay the Seller the dollar amount by which the Closing Date Net Working Capital exceeds the Target Net Working Capital Level. Any such payment due under this Section 2.02(c)shall be made in cash or same day funds within 10 days after the final determination of the Closing Date Net Working Capital pursuant to Section 2.02(b).

(d) In the event the Purchaser elects to make a Code Section 338(h)(10) Election with Seller’s consent as provided in Section 5.08(i) of this Agreement, the Purchase Price shall be increased to the extent necessary to satisfy the indemnification provided to the Seller under Section 5.08(i).

The plans set forth on Schedule 3.11(d) have assets equal to their liabilities on a termination basis and there would be no withdrawal liability from any Multiemployer Plan if the Target were to withdraw from such plan on the Closing Date.

Section 5.08

Tax Matters.

(a) Tax Indemnification. Each of the Seller and the Guarantor (a “Tax Indemnifying Party”) shall jointly and severally indemnify Target, Purchaser, and each Purchaser Affiliate (a “Tax Indemnified Party”) and hold them harmless from and against, any loss, claim, liability, expense, or other damage attributable to (i) all Taxes (or the non-payment thereof) of Target for all Taxable periods ending on or before the Closing Date and the portion through the end of the Closing Date for any Taxable period that includes (but does not end on) the Closing Date (“Pre-Closing Tax Period”), (ii) all Taxes of any member of an affiliated, consolidated, combined or unitary group of which Target (or any predecessor) is or was a member on or prior to the Closing Date, including pursuant to Treasury Regulation Section 1.1502-6 or any analogous or similar state, local, or foreign

law or regulation, and (iii) any and all Taxes of any person (other than Target) imposed on Target as a transferee or successor, by contract or pursuant to any law, rule, or regulation, which Taxes relate to an event or transaction occurring before the Closing (a “Tax Loss”). In determining the amount of Seller and the Guarantor’s liability, any Losses relating to Taxes will be calculated net of any future tax benefits actually realized by Purchaser’s Indemnified Party as the result of timing differences associated with such Tax Losses. Any audit, claim, investigation, proceeding, suit, Governmental Entity order, assertion or other dispute for Tax Losses that could have implications on the indemnification obligations under this Section 5.08 shall be referred to as a “Tax Claim” hereunder. Any indemnification obligation contained in this Section 5.08 shall be subject to the limitations on indemnification contained in Article IX.

(b)

Tax Indemnification Procedures.

(i) Notice. If any Governmental Entity makes a Tax Claim to a Tax Indemnified Party, such Tax Indemnified Party shall promptly provide a Tax Claim Notice to the Tax Indemnifying Party and if any Governmental Entity makes a Tax Claim to the Tax Indemnifying Party, the Tax Indemnifying Party shall promptly notify the Tax Indemnified Party. Any such Tax Claim Notices to the Tax Indemnifying Party shall contain factual information (to the extent known) describing any asserted Tax Claim in reasonable detail and shall be accompanied by copies of any notice or other documents from the Governmental Entity with respect to such Tax Claim. If a Tax Indemnified Party receives written notice from a Governmental Entity of any Tax Claim and fails to provide the Tax Indemnifying Party with a Tax Claim Notice of such asserted Tax Claim, then (A) if the Indemnifying Party is precluded from contesting the asserted Tax Claim in any forum as a result of the failure to give such Tax Claim Notice, the Tax Indemnifying Party shall have no obligation to indemnify the Tax Indemnified Parties for any Tax Indemnified Taxes arising from such asserted Tax Claim and (B) if the Tax Indemnifying Party is not precluded from contesting the asserted Tax Claim in any forum, but such failure to provide such Tax Claim Notice results in a monetary detriment to the Tax Indemnifying Party, then any amount which the Tax Indemnifying Party is otherwise required to pay to the Tax Indemnified Party pursuant to this Section 5.08 shall be reduced by such detriment.

(ii) Control Rights. The Tax Indemnifying Party shall control any Tax Claims using counsel of its own choosing. The Tax Indemnified Party may participate in such defense at its own expense. The Tax Indemnified Party shall provide the Tax Indemnifying Party with access to its records and personnel relating to any such Tax Claim during normal business hours and shall otherwise cooperate with the Tax Indemnifying Party in the defense or settlement thereof, and the Tax Indemnifying Party shall reimburse the Tax Indemnified Party for all of its reasonable out-of-pocket expenses in connection therewith. The Tax indemnifying Party shall provide the Tax Indemnified Party with access to its records and personnel relating to any such Tax Claim during normal business hours and shall otherwise cooperate with the Tax Indemnified Party, and the Tax Indemnified Party

shall reimburse the Indemnifying Party for all of its reasonable out-of-pocket expenses in connection with such access.

(iii) Consent to Settlement. No Tax Indemnified Party shall agree to settle or compromise any Tax Claim, which settlement or compromise may affect the liability for Tax Losses related to the Tax Indemnified Taxes without the consent of the Tax Indemnifying Party, which consent shall not be unreasonably withheld or delayed. The Tax Indemnifying Party shall not agree to settle or compromise any Tax Claim, which settlement or compromise requires or includes any admission of liability by any Tax Indemnified Party or subjects any Tax Indemnified Party to any liability for Tax Losses not covered by the indemnification provided in Section 5.8 hereof without the consent of the Tax Indemnified Party, which consent shall not be unreasonably withheld or delayed.

(iv) Expenses. The Tax Indemnifying Party shall bear all expenses in connection with any Tax Claim, except as otherwise set forth in Section 2.02(b) hereof.

(v) Payment. The Tax Indemnifying Party shall pay to the Tax Indemnified Party in readily available United States dollars any finally determined Loss resulting from a Tax Claim for Indemnified Taxes at fifteen (15) days after the Indemnified Party is required to pay such finally determined Tax Loss amount to a Governmental Entity.

(vi) Cooperation. The Tax Indemnifying Party shall keep the Tax Indemnified Parties promptly informed of all correspondence, conferences (in person or otherwise), documents, notices, and any other items, actions, or activities that relate to the defense of any Tax Claim.

(c) Straddle Period. In the case of any Taxable period that includes (but does not end on) the Closing Date (a “Straddle Period”), the amount of any Taxes based on or measured by income or receipts of Target for the Pre-Closing Tax Period shall be determined based on an interim, closing of the books as of the close of business on the Closing Date and the amount of other Taxes of Target for a Straddle Period which relate to the Pre-Closing Tax Period shall be deemed to be the amount of such tax for the entire Taxable period multiplied by a fraction the numerator of which is the number of days in the Taxable period ending on the Closing Date and the denominator of which is the number of days in such Straddle Period.

(d) Responsibility for Filing Tax Returns for Periods Through Closing Date. Seller and Guarantor shall include the income of Target (including any deferred items triggered into income by Treasury Regulation Section 1.1502-13 and any excess loss account taken into income under Treasury Regulation Section 1.1502-19) on Seller consolidated federal income Tax Returns for all periods through the Closing Date and pay any federal income Taxes attributable to such income. For all taxable periods ending on or before the Closing Date, Seller shall cause Target to join in Seller’s and Guarantor’s consolidated federal income tax return and, in jurisdictions requiring separate reporting

from Seller or Guarantor, to file separate company state and local income tax returns. Buyer shall permit Seller to review and comment on any such separate tax return prior to filing.

(e) Refunds and Tax Benefits. Any Tax refunds that are received by Buyer or Target, and any amounts credited against Taxes to which Buyer or Target become entitled, that relate to Tax periods or portions thereof ending on or before the Closing Date, that were not accrued on the Closing Financial Statement, shall be for the account of Sellers to the extent that such amounts relate to Seller or Target’s activities ending on or before the Closing Date. Buyer shall pay over to Sellers any such refund or the amount of any such credit with 30 days after receipt or entitlement thereto. In addition, to the extent that a claim for refund or a proceeding results in a payment or credit against Taxes by a taxing authority to Buyer or Target of any amount accrued on the Closing Financial Statements, Buyer shall pay such amount to Sellers with 30 days after receipt or entitlement thereto.

(f)

Cooperation on Tax Matters.

(i) Purchaser, Guarantor, Target and Seller shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of Tax Returns pursuant to Section 5.08(d) and any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other Party’s request) the provision of records and information which are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Guarantor, Target and Seller agree (a) to retain all books and records with respect to Tax matters pertinent to Target relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by Purchaser or Seller, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into any taxing authority, and (b) to give the other party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other party so requests, Target or Seller, as the case may be, shall allow the other party to take possession of such books and records.

(ii) Purchaser and Seller further agree, upon request, to use their best efforts to obtain any certificate or other document from any Governmental Entity or any other person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including, but not limited to, with respect to the transactions contemplated hereby).

(iii) Purchaser and Seller further agree, upon request, to provide the other party with all information that either party may be required to report pursuant to Code Section 6043 and all Treasury Regulations promulgated thereunder.

(g) Tax Sharing Agreements. Tax sharing agreements or similar agreements with respect to or involving Target shall be terminated as of the Closing Date and, after the Closing Date, Target shall not be bound thereby or have any liability thereunder.

(h) Certain Taxes and Fees. All transfer, documentary, sales, use, stamp, registration and other such Taxes, and all conveyance fees, recording charges and other fees and charges (including any penalties and interest) incurred in connection with consummation of the transactions contemplated by this Agreement shall be paid by the Party upon whom such Tax, fee or otherwise is imposed when due, and the relevant Party will, at its own expense, file all necessary Tax Returns and other documentation with respect to all such Taxes, fees and charges, and, if required by applicable law, the other Party will, and will cause its Affiliates to, join in the execution of any such Tax Returns and other documentation.

(i) Code Section 338(h)(10). At Purchaser’s option, Guarantor, Seller and Purchaser shall join in making an election under Code §338(h)(10) (and any corresponding elections under state, local, or foreign tax law) (collectively a “Code Section 338(h)(10) Election”) with respect to the purchase and sale of the stock of Target hereunder. Seller will pay any Tax attributable to the making of the Code Section 338(h)(10) Election and the Purchaser will indemnify the Seller against any adverse consequences arising out of any such Tax which Tax shall be computed as the amount of additional consideration necessary to cause Seller’s after-tax net proceeds from the sale of the Shares with the Section 338(h)(10) Election to be equal to the after-tax net proceeds that the Seller would have received if the Code Section 338(h)(10) Election had not been made, taking into account all applicable Taxes to the Seller that result from such Code Section 338(h)(10) Election, and shall give effect to the Tax implications to the Seller of any such additional consideration. Seller will also pay any state, local, or foreign Tax (and indemnify Purchaser and Target against any adverse consequences arising out of any failure to pay such Tax) attributable to an election under state, local, or foreign law similar to the election available under Code Section 338(g) (or which results from the making of an election under Code Section 338(g)) with respect to the purchase and sale of the stock of Target hereunder. The parties agree that any payments made under this Section 5.08(i) will be treated, for Tax purposes, as a positive adjustment to the Purchase Price. The Seller or Seller’s Representative shall provide the Purchaser with a schedule computing the amount of indemnification within 30 days after the Purchaser and the Seller have agreed to the Purchase Price Allocation (per Section 5.08(j)). Purchaser shall have 30 days to review the indemnification requested. Any dispute shall be settled by an independent appraiser or accounting firm to be mutually appointed by the Purchaser and the Seller. Purchaser shall pay the agreed upon indemnification to the Seller within 30 days of such agreement.

(j) Allocation of Purchase Price. The parties agree that the Purchase Price and the liabilities of Target (plus other relevant items) will be allocated to the assets of Target for all purposes (including Tax and financial accounting purposes) in a manner consistent with Code Sections 338 and 1060 and the regulations thereunder. Purchaser, Target and Seller shall file all Tax Returns (including amended returns and claims for refund) and information reports in a manner consistent with such allocation. The Purchaser shall prepare the Purchase Price allocation and shall deliver such allocation to the Seller within

sixty (60) days after the Closing Date. Seller shall have 20 days to review and comment upon the proposed allocation of the Purchase Price. After receiving the comments of Seller, Purchaser may accept the allocation with Seller’s comments or the Parties shall select an accounting firm, not previously employed by any of the Parties, to prepare a Purchase Price allocation which shall be binding upon the Parties.

(k)

Provided that the parties do not agree to a Code 338(h)(10) Election, then:

(i) Audits. Guarantor and Seller shall allow Target and its counsel to participate at Target’s expense in any audit of Guarantor’s consolidated federal income Tax Returns to the extent that such returns relate to Target. Seller and Guarantor shall not settle any such audit in a manner which would adversely affect Target after the Closing Date without the prior written consent of Purchaser, which consent shall not unreasonably be withheld.

(ii) Carrybacks. Guarantor and Seller shall immediately pay to Purchaser any Tax refund (or reduction in Tax liability) resulting from a carryback of a post-acquisition Tax attribute of Target into the Guarantor’s consolidated Tax Return, when such refund (or reduction) is realized by Guarantor’s group. At Purchaser’s request, Seller and Guarantor will cooperate with Target in obtaining such refund (or reduction), including through the filing of amended Tax Returns or refund claims. Purchaser agrees to indemnify Seller and Guarantor for any Taxes resulting from the disallowance of such post-acquisition Tax attribute on audit or otherwise.

Section 5.09 Payment of Bonuses. The Guarantor shall have paid all employee transaction bonuses as of the Closing Date.

Section 5.10 Audited Financial Statements. Ernst & Young will be engaged by Seller or Guarantor to opine on the Audited Financial Statements, which will be delivered within 60 days of the Closing Date. The Purchaser shall reimburse the Seller for fifty percent (50%) of the costs incurred in connection with the engagement of Ernst & Young in connection with the Audited Financial Statements.

Section 5.11 Guaranty. The Guarantor hereby absolutely, unconditionally and irrevocably guarantees all obligations and performance by the Target and Seller of all present and future covenants, conditions, agreements and undertakings of the Target or Seller under this Agreement. This Guaranty is a continuing guaranty and shall remain in full force and effect until the date on which the obligations hereunder shall have been terminated. Guarantor shall not engage in any merger, consolidation, dissolution, liquidation or transfer, distribution or sale of substantially all of its assets unless the obligations of Guarantor hereunder are assumed by the other party to such merger, consolidation, dissolution, liquidation or transfer, distribution or sale of substantially all of the assets and such other party has the financial capacity to undertake the indemnification obligations provided for in this Agreement.

Section 5.12 Employee Benefits. Purchaser agrees that until December 31, 2007 unless prior to the Closing Date, the Purchaser and Target mutually agree otherwise in writing, it will

provide Target employees with welfare benefits that are set forth on Schedule 5.12. Purchaser agrees to waive any limitations regarding pre-existing condition exclusions with regard to welfare benefits coverage and to give full credit for any co-payments made and deductibles fully or partially satisfied for the calendar year in which the Closing Date occurs with respect to Employee Welfare Benefit Plans maintained by the Purchaser or any of its subsidiaries in which employees of the Target participate after the Closing Date. Purchaser agrees to give Target employees service credit for all periods of employment with Target prior to the Closing Date, for purposes of eligibility vesting and benefit accrual, under any Employee Welfare Benefit Plan adopted or maintained by Purchaser or any of its subsidiaries, in which employees of the Target participate following the Closing Date. After the Closing Date, Purchaser shall be solely responsible for all termination and severance benefits, costs, charges and liabilities of any nature incurred with respect to termination of a Target employee after the Closing Date.

Section 7.01 Representations and Covenants.

ARTICLE VIII

FURTHER AGREEMENTS

Section 8.01 Access to Books and Records. Following the Closing Date, the Purchaser shall afford, and will cause its Affiliates to afford, to the Seller and any Affiliates of the Seller, its counsel and its accountants, during normal business hours, reasonable access to the Books and Records with respect to the period prior to the Closing Date to the extent that such access may be reasonably required by the Seller or any Affiliate of the Seller for (i) the preparation of tax returns or in connection with any audit, amended return, claim for refund or any proceeding with respect thereto and (ii) the investigation, litigation and final disposition of any claims which may have been or may be made against the Seller or such Affiliate. For a period of twenty-four (24) months, the Purchaser will not, and will cause its Affiliates to not, dispose of, alter or destroy any such Books and Records and other materials without giving 30 days’ prior notice to the Seller and the Guarantor to permit them, at their expense, to examine, duplicate or repossess such records, files, documents and correspondence.

Section 8.02 Cooperation. Following the Closing Date, the Purchaser shall cause employees of the Purchaser who prior to employment therewith were employed by the Target in connection with the business of Target, to cooperate, to the extent reasonably practicable, as long as it does not interfere with the Purchaser’s ability to complete regulatory filings on a timely basis and conduct its business in the ordinary course, with the Seller and any Affiliate of the Seller in (a) the defense of any litigation or arbitration arising out of any event that occurred on or prior to the Closing Date, (b) connection with any tax matter, (c) the defense or prosecution, as the case may be, of any third party claim in accordance with Section 9.03 hereof, and (d) such other reasonable requests as shall be made by the Seller or Guarantor in connection with the transactions contemplated by this Agreement. The costs incurred in complying with this Section 8.02 shall be borne by the requesting party. Notwithstanding the above, nothing in this Section 8.02 shall obligate Target to perform any development work or provide any assistance to Seller or any Affiliate of the Seller regarding or relating to the business or products of Seller or any Affiliate of Seller unless Target and Seller or an Affiliate of Seller have entered into a separate service agreement.

Section 8.03 Memorandum; Disclaimer of Projections. The Purchaser acknowledges that neither the Seller nor any Affiliate or representative or advisor of any of them makes or has made any representation or warranty to the Purchaser except as specifically made in this Agreement. In particular, no such person makes or has made any representation or warranty to the Purchaser with respect to (a) any information set forth in the Confidential Information Memorandum distributed by the Target in connection with the transactions contemplated by this Agreement or (b) any financial projection or forecast relating to the Target. With respect to any such projection or forecast delivered by or on behalf of the Seller or its Affiliates to the Purchaser,

the Purchaser acknowledges that (i) there are uncertainties inherent in attempting to make such projections and forecasts, (ii) it is familiar with such uncertainties, (iii) it is taking full responsibility for making its own evaluation of the adequacy and accuracy of all such projections and forecasts so furnished to it and (iv) it shall have no claim against any person with respect thereto.

Section 8.04 Use of Names. Notwithstanding any inference or prior course of conduct to the contrary, in no event shall the Purchaser or any Affiliate of the Purchaser have any right to use any corporate name or acronym of the Seller or any of its Affiliates (other than Target) in any jurisdiction, including without limitation the names and acronyms set forth in Schedule 8.03, or any registered or unregistered trademark, trade name, or any registered or unregistered service mark or any application or registration therefor, owned by, licensed to or used by the Seller or any of its Affiliates (other than Target) or any other name, term or identification that suggests, simulates or is confusing due to its similarity to any of the foregoing.

ARTICLE IX

INDEMNIFICATION

Section 9.01 Indemnification by the Seller and Guarantor. Subject to and to the extent provided in this Article IX, from and after the Closing, the Seller and the Guarantor shall, jointly and severally, indemnify, defend and hold harmless Purchaser’s Indemnified Persons, and each of them, from and against any Losses incurred or suffered by Purchaser’s Indemnified Persons, directly or indirectly, as a result of, relating to or arising from:

(a) Any misrepresentation or breach of a representation or warranty made by the Seller, the Guarantor or the Target herein;

(b) The breach of any covenant, agreement or other obligation of the Seller, the Guarantor or the Target set forth in this Agreement or in any documents delivered pursuant to Closing, other instruments, agreements, certificates or other documents executed or delivered pursuant to or as contemplated in this Agreement; and

(c) The operation or conduct of the Target prior to the Closing Date including, but not limited to, any liability relating to products designed, manufactured or sold by Target, Seller or Guarantor prior to the Closing Date.

Section 9.02 Indemnification by Purchaser. Subject to and to the extent provided in this Article IX, from and after the Closing Date, the Purchaser shall indemnify, defend and hold harmless Seller’s Indemnified Persons, and each of them, from and against any Losses incurred or suffered by Seller’s Indemnified Persons, directly or indirectly, as a result of, relating to or arising from:

(a) Any misrepresentation or breach of a representation or warranty made by Purchaser herein;

(b) The breach of any covenant, agreement or other obligation of Purchaser set forth in this Agreement; or

(c) Any claim by any Person (other than Seller’s Indemnified Persons) to the extent alleging Losses resulting from the conduct of the Target after the Closing.

Section 9.03 Notice and Control of Litigation. If any claim or liability is asserted in writing against a party entitled to indemnification under this Article IX (the “Indemnified Party”) which would give rise to a claim under this Article IX, the Indemnified Party shall notify the person giving the indemnity (“Indemnifying Party”) in writing of the same within thirty (30) days of receipt of such written assertion of a claim or liability. The Indemnifying Party shall have the right to defend a claim and control the defense, settlement and prosecution of any litigation. If the Indemnifying Party, within twenty (20) days after notice of such claim, fails to defend such claim, the Indemnified Party will (upon further notice to the Indemnifying Party) have the right to undertake the defense, compromise or settlement of such claim on behalf of and for the account and risk of the Indemnifying Party. Anything in this Section 9.03 notwithstanding, (i) if there is a reasonable probability that a claim may materially and adversely affect the Indemnified Party other than as a result of money damages or other money payments, the Indemnified Party shall have the right, at its own cost and expense, to defend, compromise and settle such claim, and (ii) the Indemnifying Party shall not, without the written consent of the Indemnified Party, settle or compromise any claim or consent to the entry of any judgment which does not include as an unconditional term thereof the giving by the claimant to the Indemnified party a release from all liability in respect to such claim. All parties agree to cooperate fully as necessary in the defense of such matters. Should the Indemnified Party fail to notify the Indemnifying Party in the time required above, the Indemnifying Party shall be relieved of its obligations pursuant to this Article IX only to the extent such failure to notify in the time required above materially adversely affects the Indemnifying Party’s ability to defend such matter.

Section 9.04 Notice of Claim. If an Indemnified Party becomes aware of any breach of the representations or warranties of the Indemnifying Party hereunder or any other basis for indemnification under this Article IX, the Indemnified Party shall notify the Indemnifying Party in writing of the same within forty-five (45) days after becoming aware of such breach or claim, specifying in detail the circumstances and facts which give rise to a claim under this Article IX. Should the Indemnified Party fail to notify the Indemnifying Party within the time frame required above, it shall not relieve the Indemnifying Party of its obligations hereunder except to the extent that the Indemnifying Party is materially prejudiced thereby.

Section 9.05 Remedies Cumulative. The remedies provided in this Agreement shall be cumulative and shall not preclude any party from asserting any other right, or seeking any other remedies, against the other party or any third Person; provided however, that (other than for Seller or Purchaser Unlimited Claims, as defined in Section 9.07 below) the sole and exclusive remedy for monetary damages under this Agreement shall be the Escrow Amount, except for any claims arising from any fraud on behalf of Purchaser, Seller, Target or Guarantor.

Section 9.06 Survival and Cap. The representations, warranties, covenants and agreements made by the Parties to this Agreement shall survive the Closing and shall continue in full force and effect for fifteen (15) months following the Closing Date; except that (i) the representations and warranties set forth in Section 3.12 and the covenant set forth in Section 5.08 shall survive until the expiration of the applicable statute of limitations plus sixty (60) days and (ii) the representations and warranties set forth in Sections 3.01, 3.02, 3.04 and 3.19 shall survive for

three (3) years. The indemnification obligations of the Parties shall survive Closing and continue in full force and effect after their applicable expiration if a notice of claim has been submitted on or prior to the expiration of the applicable representation, warranty or covenant. In no event shall the aggregate Losses payable by an Indemnifying Party pursuant to this Article IX with respect to all claims for indemnification (other than the Seller or Purchaser Unlimited Claims, as defined in Section 9.07 below), including any working capital adjustments pursuant to Section 2.02, exceed an amount equal to the Escrow Amount. In addition, notwithstanding the preceding sentence, in the event that the working capital adjustment provided in Section 2.02 reduces the Purchase Price for the Purchaser, the aggregate potential indemnification liability herein shall be reduced dollar-for-dollar, by the amount by which the working capital was adjusted in favor of Purchaser.

Section 9.07

Limitations on Indemnification.

(a) The Seller and the Guarantor shall have no indemnification obligation under Article IX, except to the extent that the aggregate amount of all indemnification claims exceeds Two Hundred Thousand Dollars ($200,000), calculated for purposes of this Article IX without regard to any materiality standard contained in the applicable representation, warranty or covenant, and in which case the Seller and Metrologic shall be responsible for all amounts in excess of Two Hundred Thousand Dollars ($200,000); provided, however, that Losses payable with respect to claims for indemnification arising from any fraud on the part of the Seller, for which the Seller shall have liability for the first dollar of such claim without any limitation (the “Seller Unlimited Claims”).

(b) The Purchaser shall have no indemnification obligation under Article IX, except to the extent that the aggregate amount of all indemnification claims exceeds Two Hundred Thousand Dollars ($200,000), calculated for purposes of this Section 9 without regard to any materiality standard contained in the applicable representation, warranty or covenant, and in which case the Purchaser shall be responsible for all amounts in excess of Two Hundred Thousand Dollars ($200,000); provided, however, that Losses payable with respect to any claims arising from any fraud on the part of the Purchaser, for which the Purchaser shall have liability for the first dollar of such claim without any limitation (the “Purchaser Unlimited Claims”).

Section 9.08 Satisfaction of Claims. Claims by the Purchaser against the Seller or Guarantor for Losses pursuant to this Agreement shall be satisfied (i) first, from the Escrow Amount, to the extent of the Escrow Amount, in accordance with the terms of the Escrow Agreement, and (ii) second, then, solely with respect to Seller Unlimited Claims, from the Seller or Guarantor directly.

ARTICLE X

TERMINATION PRIOR TO CLOSING

failure of a Closing condition and the Closing will occur or the Purchaser may choose not to Close and, in either case, the Guarantor, Seller and Target shall have no liability therefor following the termination or following the Closing, as the case may be; provided , however, that the foregoing shall not apply to any of Guarantor’s, Seller’s or Target’s’ willful breach, willful inaccuracy or willful failure. This Agreement may be terminated at any time prior to the Closing:
