For purposes of this Agreement, “Working Capital” shall mean the current assets of Seller as of the Closing Date (including accounts receivable (net of allowance for doubtful accounts), inventory (net of reserve for excess and obsolete inventory), prepaid assets (including amounts accrued for fuel Taxes) and other Acquired Assets that constitute current assets, including investments, but excluding cash and cash equivalents, which cash and cash equivalents shall be distributed to, or retained by, Seller prior to the Closing, less the Assumed Liabilities that constitute current liabilities of Seller as of the Closing Date (including accounts payable and accrued expenses, but excluding amounts accrued for insurance premiums, all Taxes, expenses for management incentive costs, pension costs, severance, workers’ compensation costs and PerkinElmer savings plan and employee stock purchase plan costs), and shall be calculated in accordance with U.S. GAAP and on a basis consistent with Seller’s accounting methods, treatments, principles and procedures used in the preparation of the Financial Statements referred to in Section 2.6 of this Agreement but only with reference to Acquired Assets and Assumed Liabilities.

(b) If Seller in good faith disputes the Closing Working Capital Amount as shown on the Closing Working Capital Statement prepared by Buyer, Seller shall deliver to Buyer within 30 days after receipt of the Closing Working Capital Statement a statement (the “Dispute Notice”) setting forth Seller’s calculation of Seller’s determination of the correct Closing Working Capital Amount and describing in reasonable detail the basis for the determination of such different Closing Working Capital Amount. The Parties shall use

-15-

reasonable efforts to resolve such differences regarding the determination of the Closing Working Capital Amount for a period of 30 days after Buyer has given the Dispute Notice. If the Parties resolve such differences, the Closing Working Capital Amount agreed to by the Parties shall be deemed to be the “Final Closing Working Capital Amount” and the Closing Working Capital Statement agreed to by the Parties shall be deemed to be the “Final Closing Working Capital Statement.”

(c) If the Parties do not reach a final resolution on the Closing Working Capital Amount within 30 days after Seller has given the Dispute Notice, unless the Parties mutually agree to continue their efforts to resolve such differences, Grant Thornton LLP (the “Neutral Accountant”) shall resolve such differences, pursuant to an engagement agreement executed by the Parties and the Neutral Accountant, in the manner provided below. The Parties shall each be entitled to make a presentation to the Neutral Accountant, pursuant to procedures to be agreed to among Seller, Buyer and the Neutral Accountant (or, if they cannot agree on such procedures, pursuant to procedures determined by the Neutral Accountant), regarding such Party’s calculation of the Closing Working Capital Amount; and the Neutral Accountant shall be required to resolve the differences between the Parties and determine the Closing Working Capital Amount within twenty (20) Business Days thereafter. The Closing Working Capital Amount determined by the Neutral Accountant shall be deemed to be the Final Closing Working Capital Amount and the Closing Working Capital Statement, as adjusted to reflect such determination, shall be deemed to be the Final Closing Working Capital Statement. Such determination by the Neutral Accountant shall be conclusive and binding upon the Parties, absent fraud or manifest error.

(d) The Neutral Accountant shall not be authorized or permitted to:

-16-

(i) determine any questions or matters whatsoever under or in connection with this Agreement except for the resolution of differences between the Parties regarding the determination of the Closing Working Capital Amount in accordance with this Section 1.4;

(ii) resolve any such differences by making an adjustment to the Closing Working Capital Statement that is outside of the range defined by amounts as finally proposed by the Parties; or

(iii) apply any accounting methods, treatments, principles or procedures other than as described in Section 1.4(a).

(e) Seller, on the one hand, and Buyer, on the other hand, shall each pay one half of the fees and expenses of the Neutral Accountant;provided that if the Neutral Accountant determines that one Party has adopted a position or positions with respect to the Closing Working Capital Statement that is frivolous or clearly without merit, the Neutral Accountant (i) may, in its discretion, assign a greater portion of any such fees and expenses to such Party and (ii) shall provide to the Parties a written explanation of its reasons for making such a determination.

(f) The Parties agree that the procedure set forth in this Section 1.4 for resolving disputes with respect to the Closing Working Capital Amount shall be the sole and exclusive method for resolving any such disputes, provided that this provision shall not prohibit any Party from instituting litigation to enforce the ruling of the Neutral Accountant.

(g) Failure of Seller to deliver a Dispute Notice within 30 days after receiving the Closing Working Capital Statement shall constitute acceptance of the Closing Working Capital Amount set forth on the Closing Working Capital Statement, whereupon such Closing

-17-

Working Capital Amount shall be deemed to be the Final Closing Working Capital Amount and the Closing Working Capital Statement shall be deemed to be the Final Closing Working Capital Statement. Delivery by Seller of a Dispute Notice shall constitute final and binding acceptance by Seller of all portions of the Closing Working Capital Statement other than those specifically identified in the Dispute Notice as being subject to a good faith dispute.

(h) If the Final Closing Working Capital Amount is less than $1,726,900, then Seller shall pay to Buyer an amount equal to the difference between $1,726,900 and the Final Closing Working Capital Amount. If the Final Closing Working Capital Amount is more than $1,726,900, then Buyer shall pay to Seller an amount equal to the difference between the Final Closing Working Capital Amount and $1,726,900. Any payment pursuant to this Section 1.4(h) shall be made in cash by wire transfer of immediately available funds into an account or accounts designated by Buyer or Seller, as the case may be, within five Business Days after the date on which the Final Closing Working Capital Amount is determined pursuant to this Section 1.4.

(i) For purposes of this Agreement, “Adjusted Purchase Price” means the Purchase Price plus, if applicable, the amount of the payment required to be made by Buyer to Seller pursuant to the second sentence of Section 1.4(h) or minus, if applicable, the amount of the payment required to be made by Seller to Buyer pursuant to the first sentence of Section 1.4(h).

1.5    Consents to Assignment. Anything in this Agreement to the contrary notwithstanding, this Agreement shall not constitute an agreement to assign or transfer any asset, agreement, lease, authorization, license or permit, or any claim, right or benefit arising thereunder or resulting therefrom, if an attempted assignment or transfer thereof, without the consent of a third party thereto or of the issuing Governmental Entity (as defined in Section

-18-

2.4(b)), as the case may be, would constitute a breach or default thereof, would result in a violation of the rights of any such third party, would be ineffective, or would in any way adversely affect the rights of Seller or Buyer thereunder. If such consent (a “Deferred Consent”) has not been obtained by the Closing, then (a) the asset, agreement, lease, authorization, license or permit to which such Deferred Consent relates (a “Deferred Item”) shall be withheld from sale pursuant to this Agreement without any reduction in the Purchase Price, (b) from and after the Closing, Seller and Buyer will cooperate, in all reasonable respects, to obtain such Deferred Consent as soon as practicable after the Closing, provided that Seller shall not be required to make any payments or agree to any material undertakings in connection therewith and (c) until such Deferred Consent is obtained, Seller and Buyer shall cooperate, in all reasonable respects, in any lawful and commercially reasonable arrangement reasonably proposed by Buyer under which (i) Buyer would obtain (without infringing upon the legal rights of any third party) the economic claims, rights and benefits (net of the amount of any related Tax costs and any other liabilities or obligations imposed on Seller or any of its Affiliates under the Deferred Item) and (ii) Buyer would assume any related economic burden (including the amount of any related Tax costs and any other liabilities or obligations imposed on Seller or any of its Affiliates) with respect to the Deferred Item.

(d) The Parties agree that the only representations and warranties of Seller herein or in the Texas Real Property Agreement as to any Environmental Matters are those contained in this Section 2.17. Without limiting the generality of the foregoing, Buyer specifically acknowledges that the representations and warranties contained in Sections 2.14, 2.18 and 2.19 do not relate to Environmental Matters.

2.18    Legal Compliance. To Seller’s knowledge, Seller is in compliance with all applicable laws of any federal, state or foreign government, or any Governmental Entity, currently in effect, except where the failure to comply therewith would not reasonably be expected to result in a Seller Material Adverse Effect. Seller has not received written notice of any pending action, suit, proceeding, hearing, investigation, claim, demand or notice alleging any failure to so comply.

2.19    Permits. To Seller’s knowledge, (a) Seller is not in violation of or default under any permit, license, franchise or authorization from any Governmental Authority used in its business or operations as presently conducted and material to the business or operations of Seller (collectively, the “Permits”) and (b) no Permit will be revoked, terminated prior to its normal expiration date or not renewed solely as a result of the consummation of the transactions contemplated by this Agreement, except, in either case, for (i) any violation, default, revocation, termination or renewal that would not reasonably be expected to result in a Seller Material Adverse Effect and (ii) other than Permits which are not transferable or assignable under Environmental Law.

2.20    Business Relationships with Affiliates. The Disclosure Schedule lists any written agreements whereby any Affiliate of Seller directly or indirectly (a) owns any property or right,

-36-

tangible or intangible, which is used in and material to the Business, (b) has any material claim or cause of action against Seller, or (c) owes any money to, or is owed any money by, Seller.

2.22    Entire Business. Except for the Excluded Assets and any Deferred Items, and assuming Buyer (or one or more of its Affiliates) has the ability to provide to the Business all corporate-level services currently provided to the Business by Seller and its Affiliates, the Acquired Assets are, when utilized by a labor force substantially similar to that employed by Seller on the date hereof, adequate to conduct the Business immediately following the Closing in all material respects as currently conducted.

2.23    Accounts Receivable. All accounts receivable that are reflected on the Most Recent Balance Sheet or on the accounting records of Seller as of the Closing Date represent or will represent valid obligations arising from sales actually made or services actually performed by Seller in the ordinary course of business. Seller has not received any written notice from any account debtor of an account receivable that any such account receivable is subject to any contest, claim or right of set-off, other than returns in the ordinary course of business. Except to the extent paid prior to the Closing Date, to the knowledge of Seller, such accounts receivable are or will be as of the Closing Date current and collectible net of the respective reserves shown on the Most Recent Balance Sheet within ninety (90) days after the day on which it first becomes due and payable. To the knowledge of Seller, there is no contest, claim, defense or right of setoff, other than returns in the ordinary course of business of Seller, under any Contract with

-37-

any account debtor of an account receivable relating to the amount or validity of such account receivable.

2.24    Inventories. All items included in the Inventories consist of a quality and quantity usable and, with respect to finished good, saleable in the ordinary course of business of Seller except for obsolete items and items of below-standard quality, all of which have been written off or written down to net realizable value in the Most Recent Balance Sheet or on the accounting records of Seller as of the Closing Date, as the case may be. Seller is not in possession of any inventory not owned by Seller, including goods already sold. All of the Inventories have been valued at the lower of cost or market on a weighted-average basis. Inventories now on hand that were purchased after the date of the Most Recent Balance Sheet were purchased in the ordinary course of business of Seller at a cost not exceeding market prices prevailing at the time of purchase. The quantities of each item of Inventories (whether raw materials, work-in-process or finished goods) are based upon a three-year forecast of consumption. Work-in-process Inventories are now valued, and will be valued on the Closing Date, in accordance with GAAP.

(b) to the extent resulting from the conduct or operations of the Business or operation or use of the Acquired Assets from and after the Closing; or

(c) to the extent resulting from or constituting Assumed Liabilities.

6.3    Claims for Indemnification.

(a)Third-Party Claims. All claims for indemnification made under this Agreement resulting from, related to or arising out of a third-party claim against an Indemnified Party (as defined in this Section 6.3(a)) shall be made in accordance with the following procedures. A person entitled to indemnification under this Article VI (an “Indemnified Party”) shall give prompt written notification to the person from whom indemnification is sought (the “Indemnifying Party”) of the commencement of any action, suit or proceeding relating to a third-party claim for which indemnification may be sought or, if earlier, upon the assertion of any such claim by a third party. Within 30 days after delivery of such notification, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of such action, suit, proceeding or claim with counsel reasonably satisfactory to the Indemnified Party.

-46-

If the Indemnifying Party does not assume control of such defense, the Indemnified Party shall control such defense. The Party not controlling such defense may participate therein at its own expense;provided that if the Indemnifying Party assumes control of such defense and the Indemnified Party reasonably concludes, based on advice from counsel, that the Indemnifying Party and the Indemnified Party have conflicting interests with respect to such action, suit, proceeding or claim (other than the conflicting interests inherent in one party being the Indemnifying Party and the other party being the Indemnified Party), the reasonable fees and expenses of counsel to the Indemnified Party solely in connection therewith shall be considered “Damages” for purposes of this Agreement;provided,however, that in no event shall the Indemnifying Party be responsible for the fees and expenses of more than one counsel for all Indemnified Parties. The Party controlling such defense shall keep the other Party advised of the status of such action, suit, proceeding or claim and the defense thereof and shall consider recommendations made by the other Party with respect thereto. The Indemnified Party shall not agree to any settlement of such action, suit, proceeding or claim without the prior written consent of the Indemnifying Party. The Indemnifying Party shall not agree to any settlement of such action, suit, proceeding or claim that does not include a complete release of the Indemnified Party from all liability with respect thereto or that imposes any liability or obligation on the Indemnified Party without the prior written consent of the Indemnified Party, which consent shall not be unreasonably withheld, conditioned or delayed. If the Indemnifying Party is conducting the defense, it shall do so in a manner which does not unreasonably interfere with, disrupt or otherwise adversely impact the business of the Indemnified Party.

(b)Procedure for Other Claims. An Indemnified Party wishing to assert a claim for indemnification under this Article VI which is not subject to Section 6.3(a) shall

-47-

deliver to the Indemnifying Party a written notice (a “Claim Notice”) which contains (i) a description and the amount (the “Claimed Amount”) of any Damages incurred by the Indemnified Party, (ii) a statement that the Indemnified Party is entitled to indemnification under this Article VI and a reasonable explanation of the basis therefor, and (iii) a demand for payment in the amount of such Damages. Within 30 days after delivery of a Claim Notice, the Indemnifying Party shall deliver to the Indemnified Party a written response in which the Indemnifying Party shall: (I) agree that the Indemnified Party is entitled to receive all of the Claimed Amount (in which case such response shall be accompanied by a payment by the Indemnifying Party to the Indemnified Party of the Claimed Amount, by check or by wire transfer), (II) agree that the Indemnified Party is entitled to receive part, but not all, of the Claimed Amount (the “Agreed Amount”) (in which case such response shall be accompanied by a payment by the Indemnifying Party to the Indemnified Party of the Agreed Amount, by check or by wire transfer), or (III) contest that the Indemnified Party is entitled to receive any of the Claimed Amount. If the Indemnifying Party in such response contests the payment of all or part of the Claimed Amount, the Indemnifying Party and the Indemnified Party shall use good faith efforts to resolve such dispute. If such dispute is not resolved within 60 days following the delivery by the Indemnifying Party of such response, the Indemnifying Party and the Indemnified Party shall each have the right to submit such dispute to a court of competent jurisdiction in accordance with the provisions of Section 11.14.

6.4    Survival.

(a) The representations and warranties of Seller and Buyer set forth in this Agreement and the certificates delivered at Closing pursuant to Sections 5.1(d) and 5.2(d) shall survive the Closing and the consummation of the transactions contemplated hereby and continue

-48-

until the 18-month anniversary of the Closing Date, at which time they shall expire. Notwithstanding the foregoing, the representations and warranties of Seller contained in Sections 2.1, 2.2 and 2.3 and of Buyer contained in Sections 3.1 and 3.2 shall survive the Closing and the consummation of the transactions contemplated hereby without limitation.

(b) None of the covenants or other agreements contained in this Agreement shall survive the Closing Date other than those which by their terms contemplate performance after the Closing Date, and each such surviving covenant and agreement shall survive the Closing only until the expiration of the term of the undertaking set forth in such agreement and covenant.

(c) Except as set forth in Section 6.4(d), no Party shall have any liability or obligation of any nature with respect to any representation, warranty, agreement or covenant after the expiration thereof.

(d) Any claim that is properly asserted in writing pursuant to Section 6.3 prior to the expiration as provided in Sections 6.4(a) and 6.4(b) of the representation, warranty, covenant or agreement that is the basis for such claim shall survive until such claim is finally resolved and satisfied.

6.5    Limitations.

(a) Subject to Section 11.13 and except with respect to claims made pursuant to Article VIII or Article IX, from and after the Closing, the rights of the Indemnified Parties under this Article VI shall, except in cases involving fraud, be the sole and exclusive remedies of the Indemnified Parties and their respective Affiliates with respect to claims resulting from any breach of representation or warranty or failure to perform any covenant or agreement contained in this Agreement. Subject to Section 11.13, from and after the Closing, the rights of Buyer and

-49-

Seller and their respective Affiliates under Article VIII shall, except in cases involving fraud, be the sole and exclusive remedy of Buyer and Seller and their respective Affiliates with respect to the subject matter of Article VIII. Subject to Section 11.13, from and after the Closing, the rights of Buyer and Seller and their respective Affiliates under Article IX shall, except in cases involving fraud, be the sole and exclusive remedy of Buyer and Seller and their respective Affiliates with respect to the subject matter of Article IX. Without limiting the generality of the foregoing three sentences, in no event shall either Buyer or Seller, or their respective successors or permitted assigns, be entitled to claim or seek rescission of the transactions consummated under this Agreement.

(b) Notwithstanding anything to the contrary contained in this Agreement, each of the following four limitations shall apply:

(i) the aggregate liability of Seller for all Damages under this Article VI and Article VIII shall not exceed an amount equal to $12,075,000;

(ii) no individual claim or series of related claims for indemnification under Sections 6.1(a)(i) or 6.2(a)(i), shall be valid and assertable unless it is (or they are) for an amount in excess of $25,000;

(iii) Seller shall be liable under Section 6.1(a)(i), and Buyer shall be liable under Section 6.2(a)(i), for only that portion of the aggregate Damages under such sections, considered together, which exceeds $345,000 (it being understood that (A) Seller shall not be liable, in any event, for the first $345,000 of said Damages under Section 6.1(a)(i) and (B) Buyer shall not be liable, in any event, for the first $345,000 of said Damages under Section 6.2(a)(i)); and

-50-

(iv) Neither Buyer nor Seller shall be entitled to make any claim for indemnification with respect to any matter to the extent the Purchase Price has been adjusted to reflect such matter pursuant to Section 1.4, and the amount of any Damages for which indemnification is provided under this Article VI, or under Article VIII or Article IX, shall be calculated net of any accruals, reserves or provisions reflected in the Final Closing Working Capital Statement relating thereto.

(c) In no event shall any Indemnifying Party be responsible and liable for any Damages or other amounts under this Article VI or under Article VIII that are (i) consequential, in the nature of lost profits, diminutions in value, special or punitive or otherwise not actual Damages or (ii) contingent, unless and until such Damages are actual and mature. Buyer shall (and shall cause the Business to) use commercially reasonable efforts to pursue all legal rights and remedies available in order to minimize the Damages for which indemnification is provided to Buyer by Seller under Article VI or Article VIII.

(d) The amount of any Damages for which indemnification is provided under this Article VI or under Article VIII shall be reduced by any related recoveries to which the Indemnified Party is entitled under insurance policies or other related payments received or receivable from third parties and any Tax benefits actually received by the Indemnified Party or any of its Affiliates or for which the Indemnified Party or any of its Affiliates is eligible on account of the matter resulting in such Damages or the payment of such Damages. An Indemnified Party shall use commercially reasonable efforts to pursue, and to cause its Affiliates to pursue, all insurance claims and Tax benefits to which it may be entitled in connection with any Damages it incurs, and each of Buyer, Seller and the Indemnified Party with respect to any indemnification claim shall cooperate with each other in pursuing insurance claims with respect

-51-

to any Damages or any indemnification obligations with respect to Damages. If an Indemnified Party (or an Affiliate) receives any insurance payment in connection with any claim for Damages for which it has already received an indemnification payment from the Indemnifying Party, it shall pay to the Indemnifying Party, within 10 days of receiving such insurance payment, an amount equal to the excess of (i) the amount previously received by the Indemnified Party under this Article VI with respect to such claim plus the amount of the insurance payments received, over (ii) the amount of Damages with respect to such claim which the Indemnified Party has become entitled to receive under this Article VI.

6.6    Treatment of Indemnification Payments. All indemnification payments made under this Agreement shall be treated by the Parties as an adjustment to the Adjusted Purchase Price.

If, in the absence of a protective order or the receipt of a waiver hereunder, the Receiving Party is compelled to disclose any Information by judicial or administration process, such Receiving Party may so disclose the Information; provided, however, that at the written request of the Disclosing Party, the Receiving Party shall use commercially reasonable efforts to obtain, at the expense of the Disclosing Party, an order or other assurance that confidential treatment will be accorded to such portion of the Information required to be disclosed.

10.2    Covenant Not to Compete.

To the extent permitted by applicable law, each Party hereby irrevocably waives all rights to trial by jury in any action, proceeding or counterclaim (whether based on contract, tort or otherwise) arising out of or relating to this Agreement or the transactions contemplated hereby or the actions of either Party in the negotiation, administration, performance and enforcement of this Agreement.
