The Transferred Assets (other than the properties, assets, rights and claims of the Transferred Subsidiaries which shall be transferred through the purchase of the Transferred Shares pursuant to Section 2.1) shall be sold, conveyed, transferred, assigned and delivered, and the Assumed Liabilities shall be assumed, pursuant to transfer and assumption agreements or other instruments in such form as is necessary to effect a conveyance of the Transferred Assets and an assumption of the Assumed Liabilities in the jurisdictions in which such transfers are to be made, and which shall be satisfactory to the Buyer and the Company, to be executed (upon the terms and subject to the conditions hereof) on the Closing Date by the Company and the Buyer or the respective Designated Purchaser, and such other conveyance and assumption documents as may be required in such jurisdictions.

2.5 Procedures for Assets Not Transferable. Notwithstanding anything to the contrary contained in this Agreement, to the extent that the sale, conveyance, transfer, assignment or delivery or attempted sale, conveyance, transfer, assignment or delivery to the Buyer or any Designated Purchaser of any Transferred Asset (but not any Transferred Shares) is

prohibited by applicable Law or would require any governmental or third-party authorizations, approvals, consents or waivers (collectively, “Consents”) the Company shall use its, and shall cause its Subsidiaries to use their respective reasonable best efforts to obtain such Consents prior to the Closing and if any such Consents shall not have been obtained prior to the Closing, this Agreement shall not constitute a sale, conveyance, transfer, assignment or delivery thereof if any of the foregoing would constitute a breach of applicable Law or the rights of any third party; provided, however, that the Closing shall occur notwithstanding the foregoing on the terms set forth herein; provided further, however, that the Company shall not be relieved of its obligation to sell, and the Buyer of its obligation to purchase, such Transferred Assets. Following the Closing, the parties shall use their reasonable best efforts and shall cooperate with each other to obtain promptly such Consents. Pending or in the absence of such Consent, the parties shall use their respective reasonable best efforts to implement an alternative arrangement to permit the Buyer or the respective Designated Purchaser, as the case may be, to realize, receive and enjoy substantially similar rights and the full benefits of such Transferred Asset as if such impediment to assignment or transfer did not exist, and to enable Buyer or the respective Designated Purchaser to conduct the Consumables Business or the Transferred Process Operations, as the case may be, until such Consent is obtained; provided, however, that after Closing, the Company shall, and shall cause its Subsidiaries to, enforce, upon and at the request of the Buyer and for the benefit of the Buyer, any rights of the Company or its Subsidiaries arising with respect to third parties party thereto. If such Consent is obtained, the Company shall, and shall cause its Subsidiaries to, promptly convey, transfer, assign and deliver, or cause to be conveyed, transferred, assigned and delivered, such Transferred Asset to the Buyer or such Designated Purchaser.

(b) If, following the Closing Date, the Buyer or any of its Subsidiaries receives any payment or other proceeds any portion of which relates to any Excluded Assets or otherwise relates to the conduct or operation of the Company and its Subsidiaries other than the Consumables Business or the Transferred Process Operations, the Buyer shall, and shall cause its Subsidiaries to, promptly remit to the Company the amount of any such payments to the extent relating to the Excluded Assets or such other business.

ARTICLE III

PURCHASE PRICE AND ADJUSTMENTS

3.1 Purchase Price. Subject to any adjustments required pursuant to Sections 3.2 and 3.3, the aggregate purchase price for the Transferred Shares and the Transferred Assets shall be an amount equal to $21,200,000 (Twenty-One Million, Two Hundred Thousand Dollars) (the “Purchase Price”), payable in cash by wire transfer of immediately available funds to an account designated by the Company at least two (2) Business Days prior to Closing.

3.2 Payment of Purchase Price and Estimated Purchase Price Adjustment

(a) Escrow. At the Closing, the Buyer shall pay out of the Purchase Price $2,000,000 (Two Million Dollars) (the “Escrow Funds”) to be held in an escrow account in accordance with the terms of the Escrow Agreement to be executed prior to Closing in the form of Exhibit B, $1,000,000 (One Million Dollars) of which Escrow Funds shall be available for the Buyer to satisfy claims under Section 10.1(a) (other than Section 10.1(a)(iv)) and $1,000,000 (One Million Dollars) of which shall be available to satisfy claims under Section 10.1(a)(iv), including to make any payment with respect to the UK Tax Liability, if any. In the event that the UK Tax Proceeding is finally resolved, which resolution shall be in accordance with the procedures prescribed by Section 6.1, within one (1) year of the Closing Date, and the amount paid, if any, with respect thereto is less than $1,000,000 (One Million Dollars), the Buyer shall instruct the escrow agent to (i) pay any amounts owed in respect of the UK Tax Liability to the party to which it is due, (ii) deliver to the Company an amount equal to the excess of $1,000,000 (One Million Dollars) over the amount paid to finally settle and resolve the UK Tax Liability, if any, and (iii) deliver the remaining Escrow Funds, if any, within three (3) Business Days after the date that is one (1) year after the Closing Date (such one (1) year and three (3) Business Day period, as extended by this sentence, the “Initial Closing Escrow Period”), except that such period shall be increased, if at all, to the extent that the Buyer has become aware of the assertion of any claim or of the commencement of any Proceeding at law or in equity as to which it is entitled to indemnification hereunder and has notified the Company thereof in accordance with Article X prior to the end of the Closing Escrow Period until such time as all such claims have been finally resolved in accordance with the procedures set forth in the Escrow Agreement. In addition, in the event that the UK Tax Proceeding is not finally resolved within the Initial Closing Escrow Period, in addition to any other Escrow Funds being held by the Escrow Agent with respect to any unresolved claims (other than the UK Tax Proceeding), $1,000,000 of the Escrow Funds shall continue to be held by the escrow agent and be available for the Buyer in respect of the UK Tax Liability until such time as the UK Tax Proceeding is finally resolved in accordance with the procedures prescribed in Section 6.1. Upon such resolution in accordance with the procedures prescribed in Section 6.1, and after payment of the Escrow Funds in satisfaction of the UK Tax Liability, if any, and resolution and payment of all other remaining claims, any remaining Escrow Funds shall be distributed to the Company, subject to the terms of the Escrow Agreement.

(b) Estimated Purchase Price Adjustment. No later than three (3) Business Days prior to the Closing Date, the Company shall deliver to the Buyer a statement (the “Preliminary Closing Date Net Working Capital Statement”) setting forth the Company’s good faith

estimate (the “Preliminary Closing Date Net Working Capital”) of (i) the total Inventory of the Consumables Business plus (ii) the total accounts receivable of the Consumables Business minus (ii) the total accounts payable of the Consumables Business, in each case, calculated as of the Closing Date (the “Closing Date Net Working Capital”), calculated in accordance with GAAP, the methodology used in preparing the Consumables Business Balance Sheet and Section 3.2(b) of the Company Disclosure Schedule, which shall be certified by the Company’s chief financial officer (for the avoidance of doubt, the accounts receivable and accounts payable of the Consumables Business shall include all such accounts with respect to the Quest, Trident and Nautalis Discontinued Systems, Consumables and Services line of the Consumables Business). In the event that the Buyer does not agree with the Company’s estimate, the Company and the Buyer shall negotiate in good faith to mutually agree as promptly as practicable on an acceptable estimate of the Preliminary Closing Date Net Working Capital Statement. At the Closing, the amount of the Purchase Price that the Buyer shall be required to pay to the Company pursuant to this Agreement shall be adjusted by the difference between the Preliminary Closing Date Net Working Capital and the Target Net Working Capital. If the Preliminary Closing Date Net Working Capital exceeds the Target Net Working Capital, the amount of the Purchase Price paid by the Buyer to the Company at Closing shall be increased dollar-for-dollar by the amount of such excess, and if the Preliminary Closing Date Net Working Capital is less than the Target Net Working Capital, the amount of the Purchase Price paid at the Closing shall be decreased dollar-for-dollar by such shortfall, a portion of which shall be paid to the escrow agent pursuant to paragraph (a) above. The Purchase Price shall thereafter be subject to further adjustment as provided in Section 3.3.

3.3 Closing Date Net Working Capital Statement; Schedule of Cash and Cash Equivalents; and Actual Adjustment Amount.

(a) No later than sixty (60) days after the Closing Date, the Company shall prepare (i) a balance sheet of the Consumables Business, which balance sheet shall be prepared in accordance with GAAP, the methodology used in preparing the Consumables Business Balance Sheet and Section 3.2(b) of the Company Disclosure Schedule (the “Closing Statement”), (ii) a statement of the actual Closing Date Net Working Capital (such statement, as finally determined pursuant to the provisions of this Section 3.3, the “Closing Date Net Working Capital Statement”), which statement shall be prepared in accordance with GAAP, the methodology used in preparing the Consumables Business Balance Sheet and Section 3.2(b) of the Company Disclosure Schedule, (iii) a statement of the actual cash and cash equivalents held by the Transferred Subsidiaries as of the Closing Date (such statement, as finally determined pursuant to the provisions of this Section 3.3, the “Closing Date Cash Statement”), which Closing Date Net Working Capital Statement and Closing Date Cash Statement shall be prepared in accordance with GAAP, the methodology used in preparing the Consumables Business Balance Sheet and Section 3.2(b) of the Company Disclosure Schedule, and derived from the Closing Statement, and (iv) a statement setting forth the aggregate dollar amount of the accounts payable of the Process Business transferred to the Buyer at Closing (the “Accounts Payable Statement”). The Buyer shall cooperate with the Company and its accountants to the extent required to enable the Company to prepare the Closing Statement, the Closing Date Net Working Capital Statement, the Closing Date Cash Statement and the Accounts Payable Statement in accordance with this Agreement. In connection with the preparation of the Closing Date Net Working Capital Statement, the Buyer and the Company shall jointly conduct a

physical inventory count of the Inventory of the Consumables Business (the “Inventory Count”), including all raw materials, work-in-process, finished products, supplies, accessories, packaging materials, goods or parts, in each case that are (i) used or held for use principally in the conduct or operation of the Consumables Business by the Company or its Subsidiaries (including the Transferred Subsidiaries) or (ii) in the possession of third parties, commencing at a mutually agreed upon date within ten (10) days prior to the Closing Date and be reconciled to, and completed by, the Closing Date. Any disputes with respect to the Inventory Count shall be submitted to the Independent Accounting Firm in accordance with the provisions of Section 3.3(c).

(b) The Buyer may dispute the Closing Date Net Working Capital Statement, the Closing Date Cash Statement, the Closing Statement and the Accounts Payable Statement by notifying the Company within thirty (30) days after its receipt thereof. During such 30-day period, and until the Closing Date Net Working Capital Statement, the Closing Date Cash Statement, the Closing Statement and the Accounts Payable Statement are finally determined, employees of the Buyer and its accountants shall be entitled to access to the Company’s and its accountants’ work papers prepared in connection with the Closing Date Net Working Capital Statement, the Closing Date Cash Statement, the Closing Statement and the Accounts Payable Statement and shall be entitled to review and discuss such work papers with the Company and its accountants. Any notice delivered in accordance with this Section 3.3(b) shall specify in reasonable detail the nature of any disagreement so asserted. If the Buyer does not so notify the Company within such period, the Closing Date Net Working Capital Statement, the Closing Date Cash Statement, the Closing Statement and the Accounts Payable Statement shall be final, binding and conclusive on the parties. If the Buyer does so notify the Company, the Buyer and the Company and their respective accountants shall attempt to reconcile their differences, and any resolution by them as to any disputed amounts shall be final, binding and conclusive on the parties thereto.

(c) If the Buyer and the Company are unable to reach a resolution with respect to all of the items specified in a notice provided pursuant to Section 3.3(b) within twenty (20) days after receipt by the Company of such notice, then either party may submit the items remaining in dispute for resolution to KPMG LLP, provided that if at such time either party has a conflict with respect to KPMG LLP, the parties shall select another mutually acceptable firm (such firm, the “Independent Accounting Firm”), which shall, within twenty (20) days after such submission or such longer period as the Independent Accounting Firm may reasonably require, determine and report to the Buyer and the Company upon such remaining disputed items, and such determination shall be final, binding and conclusive on the parties hereto. The fees and disbursements of the Independent Accounting Firm shall be allocated between the Buyer and the Company in such manner that the Buyer shall be responsible for that portion of the fees and expenses equal to such fees and expenses multiplied by a fraction the numerator of which is the aggregate dollar value of disputed items submitted to the Independent Accounting Firm that are resolved against the Buyer (as finally determined by the Independent Accounting Firm) and the denominator of which is the total dollar value of the disputed items so submitted, and the Company shall be responsible for the remainder of such fees and expenses.

(d) Following the determination of the Closing Date Net Working Capital pursuant to this Section 3.3, (i) if the Closing Date Net Working Capital exceeds the Preliminary

Closing Date Net Working Capital, (A) the Purchase Price shall be increased dollar-for-dollar by the amount of such surplus (the “Surplus”) and (B) the Buyer shall pay to the Company the Surplus, with interest thereon as calculated pursuant to Section 3.3(e) plus the total amount reflected on the Closing Date Cash Statement, (ii) if the Closing Date Net Working Capital is less than the Preliminary Closing Date Net Working Capital, (A) the Purchase Price shall be decreased dollar-for-dollar by such deficiency (the “Deficiency”) and (B) (x) if the total amount reflected on the Closing Date Cash Statement is greater than the amount of the Deficiency, the Buyer shall pay to the Company the excess of the total amount reflected on the Closing Date Cash Statement over the Deficiency, or, (y) if the total amount reflected on the Closing Date Cash Statement is less than the amount of the Deficiency, the Company shall pay to the Buyer the excess of the Deficiency over the total amount reflected on the Closing Date Cash Statement, and (iii) if the Closing Date Net Working Capital is the same as the Preliminary Closing Date Net Working Capital, the Buyer shall pay to the Company the total amount reflected on the Closing Date Cash Statement, in each case with interest thereon as calculated pursuant to Section 3.3(e), in each case, within five (5) Business Days after the Buyer and the Company agree to the Closing Date Net Working Capital and the Closing Date Cash Statement or within five (5) Business Days after the Independent Accounting Firm finally determines the Closing Date Net Working Capital and the Closing Date Cash Statement. In the event the amount of the accounts payable of the Process Business on the Closing Date calculated in accordance with GAAP and as finally determined pursuant to this Section 3.3 is greater than $350,000, the excess over $350,000 shall be subtracted from any amounts owed by the Buyer to the Company pursuant to this Section 3.3(d) or added to any amounts owed by the Company to the Buyer pursuant to this Section 3.3(d), as the case may be. Any Surplus or Deficiency, as applicable, together with interest thereon, and any payment with respect to the Closing Date Cash Statement payable pursuant to this Agreement shall be treated for tax purposes as an adjustment to the Purchase Price.

(e) The party making such payment pursuant to Section 3.3(d), shall pay interest thereon to the other party for the period from the Closing Date to the date of payment at the London Inter-Bank Offer Rate (“LIBOR”) for six (6) month deposits in U.S. dollars as quoted on Telerate Page 3750 on the Closing Date. Such payment and interest thereon shall be made by wire transfer in immediately available funds to such account or accounts as are designated in writing by the party entitled to receive such payment no later than the second Business Day prior to the date on which such payment is due.

3.4 Allocation of Purchase Price. The Buyer and the Company agree to allocate the Purchase Price (and any Liabilities assumed hereunder that are properly treated as purchase price) in accordance with the rules under Section 1060 of the Code and the Treasury Regulations promulgated thereunder. Such allocation shall be mutually agreed upon between the parties. The Buyer and the Company agree to act in accordance with the computations and allocations as determined pursuant to this Section 3.4 in any relevant Tax Returns or filings, including any forms or reports required to be filed pursuant to Section 1060 of the Code, the Treasury Regulations promulgated thereunder or any provisions of local, state and foreign law (“1060 Forms”), and to cooperate in the preparation of any 1060 Forms and to file such 1060 Forms in the manner required by applicable law. Any issues with respect to the allocation which have not been finally resolved within 60 days following Closing shall be referred to the Independent Accounting Firm in accordance with the provisions of Section 3.3(c). Notwithstanding

the foregoing, the Buyer and the Company shall agree to a tentative allocation of the Purchase Price (and any Assumed Liabilities) between the Transferred Shares, on the one hand, and the Transferred Assets, on the other hand, within 20 days after the Amendment Date, and if the parties cannot mutually agree upon such a tentative allocation, such tentative allocation shall be prepared by the Buyer in good faith.

(a) From the date hereof until the Closing Date or, if earlier, the termination of this Agreement, the Company agrees that (i) it and its officers and directors shall not, (ii) its Subsidiaries and their officers and directors shall not, and (iii) its Representatives and controlled Affiliates shall not, take any action to, directly or indirectly (x) solicit, initiate or knowingly facilitate or encourage, or respond to, any inquiries with respect to, or the making, submission or reaffirmation of any Acquisition Proposal, or (y) engage in any discussions, negotiations or other communications relating to an Acquisition Proposal, or (z) furnish to any Person (other than the Buyer, its officers, directors, employees or Representatives), or provide any Person (other than the Buyer, its officers, directors, employees or Representatives) access to, its properties, Books and Records or any non-public information or data with respect to the Company or its Subsidiaries, this Agreement or any agreement entered into by the Buyer or the Company in connection therewith or the transactions contemplated hereby or thereby. Notwithstanding the foregoing, prior to the approval of the Acquisition and the transactions contemplated by this Agreement by the Company’s stockholders in accordance with this Agreement, the Company may (A) provide access to its properties and Books and Records in response to a request therefor by a Person who has made an unsolicited bona fide written Acquisition Proposal if the Company’s Board of Directors receives from the party so requesting such information an executed confidentiality agreement on terms substantially similar to those contained in the Confidentiality Agreement (except for such changes specifically necessary in order for the Company to be able to comply with its obligations under this Agreement) or (B) engage in any negotiations or discussions with any Person who has made an unsolicited bona fide written Acquisition Proposal, if and only to the extent that prior to taking any of the actions set forth in clauses (A) or (B) with respect to an Acquisition Proposal, (x) the Company’s Board of Directors shall have determined in good faith, after consultation with its outside legal counsel and financial advisors, that the failure to take such action would violate the fiduciary duties of the Company’s Board of Directors under applicable Law and that such Acquisition Proposal constitutes or is

reasonably likely to result in a Superior Proposal from the party that made the applicable Acquisition Proposal and (y) the Company shall have informed the Buyer promptly following (and in no event later than 24 hours after) the taking by it of any such action.

(b) Except as set forth in this Section 5.3(b), the Company may not (i) withhold, withdraw, amend, qualify, modify or change in a manner adverse to the Buyer (or propose to do any of the foregoing), or fail to make, all or any portion of its recommendation that the Company’s stockholders approve the Acquisition and the consummation of the transactions contemplated by this Agreement, (ii) approve or recommend any Acquisition Proposal or (iii) take any other action or make any other public statements in connection with the Company Special Meeting inconsistent with its recommendation (collectively, a “Change in Company Recommendation”). Notwithstanding the foregoing, if, prior to the receipt of the Stockholder Approval, if and to the extent the Company’s Board of Directors concludes in good faith, after consultation with its financial advisors and the Company’s outside legal counsel, in response to a bona fide written Acquisition Proposal which was unsolicited and did not otherwise result from a breach of Section 5.3(a), that such proposal is a Superior Proposal and that not terminating this Agreement to accept such Superior Proposal and/or failure to recommend such Superior Proposal to the stockholders of the Company would violate the fiduciary duties of the Company’s Board of Directors under applicable Law, the Company may terminate this Agreement and/or the Company’s Board of Directors may effect a Change in Company Recommendation, as applicable; provided, however, that the Company shall not terminate this Agreement pursuant to this sentence, and any purported termination pursuant to this sentence shall be void and of no force or effect, unless concurrently with such termination pursuant to this Section 5.3(b) the Company pays to the Buyer the Termination Fee payable pursuant to Section 9.2(b); provided, further, however, that the Company shall not exercise its rights to terminate this Agreement and the Company’s Board of Directors shall not effect a Change in Company Recommendation pursuant to this Section 5.3(b) unless the Company shall have delivered to the Buyer a prior written notice advising the Buyer that the Company or the Company’s Board of Directors intends to take such action with respect to a Superior Proposal, specifying in reasonable detail the material terms and conditions of the Superior Proposal, this notice to be delivered not less than five (5) Business Days prior to the time the action is taken, and during this five (5) Business Day period, the Company and its directors, officers, employees and other Representatives shall negotiate in good faith with the Buyer to make such adjustments in the terms and conditions of this Agreement such that such Acquisition Proposal would no longer constitute a Superior Proposal.

(c) The Company shall immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Persons conducted heretofore with respect to any Acquisition Proposal. The Company also shall, if it has not already done so, promptly request that each Person that has received any confidential information or data concerning the Company and its Subsidiaries in connection with its consideration of any Acquisition Proposal return or destroy all such information or data heretofore furnished.

(d) Nothing contained in this Agreement shall prohibit the Company or the Company’s Board of Directors from taking and disclosing to the Company’s stockholders a position with respect to a tender or exchange offer by a third party pursuant to Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act or from making any disclosure required by applicable Law with regard to an Acquisition Proposal.

(e) Promptly after receipt by the Company, its Subsidiaries, or any of their respective directors, officers, employees or other Representatives of an Acquisition Proposal, or if any non-public information is requested from, or any discussions or negotiations are sought to be initiated or continued with, the Company, its Subsidiaries or any of their respective directors, officers, employees or other Representatives, the Company shall provide the Buyer with written notice of the material terms and conditions of any Acquisition Proposal or the identity of any party requesting non-public information or seeking discussions or negotiations, and thereafter shall keep the Buyer informed, on a current basis, of the status and material terms and conditions of any proposals or offers. The Company shall make available to the Buyer (to the extent it has not previously done so) all non-public information made available to any Person making an Acquisition Proposal.

5.4 Non-Solicitation. The Company agrees that for a period of two (2) years from and after the Closing Date it shall not, and its shall cause its Subsidiaries not to, without the prior written consent of the Buyer, directly or indirectly, solicit to hire or hire (or cause to seek to cause to leave the employ of the Buyer or its Subsidiaries) (i) any US Consumables Employee, any Process Business Employee or any Transferred Subsidiary Employee or (ii) any Person employed by the Buyer or any of its Subsidiaries who became known to or was identified to the Company or its Subsidiaries in connection with the transactions contemplated by this Agreement, unless, in the case of clause (i) or (ii) above, such Person ceased to be an employee of the Buyer or its Subsidiaries prior to such action by the Company or any of its Subsidiaries, or, in the case of such Person’s voluntary termination of employment with the Buyer or its Subsidiaries, at least three months prior to such action by the Company or any of its Subsidiaries. Notwithstanding the foregoing, the restrictions set forth in this Section 5.4 shall not apply to bona fide public advertisements for employment placed by the Company or its Subsidiaries and not specifically targeted at the employees of the Buyer or its Subsidiaries.

5.5 Non-Competition.

(a) In consideration of the Buyer entering into this Agreement and in order that the Buyer may enjoy the full benefit of the Transferred Assets and the Acquired Businesses, for a period of three (3) years from and after the Closing Date (the “Noncompetition Period”), neither the Company nor any of its controlled Affiliates shall, directly or indirectly, whether as principal, agent, partner, officer, director, stockholder, employee, consultant or otherwise, alone or in association with any other Person, own, manage, operate, control, participate in, invest in, perform services for, or otherwise carry on, a business which, directly or indirectly, is in competition with the Consumables Business or the Transferred Process Operations in North America, Europe, Japan and any other jurisdiction where the Consumables Business or the Transferred Process Operations are currently conducted.

(b) The Company acknowledges and agrees that the remedy at law for any breach, or threatened breach, of any of the provisions of this Section 5.5 will be inadequate and, accordingly, the Company covenants and agrees that the Buyer shall, in addition to any other rights and remedies which the Buyer may have at Law, be entitled to equitable relief, including injunctive relief, and to the remedy of specific performance with respect to any breach or

threatened breach of such covenant, as may be available from any court of competent jurisdiction. In addition, the Company and the Buyer agree that the terms of the covenant in this Section 5.5 are fair and reasonable in light of the Buyer’s plans for the Transferred Assets, the Consumables Business and the Transferred Process Operation and are necessary to accomplish the full transfer of the goodwill and other intangible assets contemplated hereby. In the event that any of the covenants contained in this Section 5.5 shall be determined by any court of competent jurisdiction to be unenforceable for any reason whatsoever, then any such provision or provisions shall not be deemed void, and the parties hereto agree that said limits may be modified by the court and that said covenant contained in this Section 5.5 shall be amended in accordance with said modification, it being specifically agreed by the parties that it is their continuing desire that this covenant be enforced to the full extent of its terms and conditions or if a court finds the scope of the covenant unenforceable, the court should redefine the covenant so as to comply with applicable Law.

5.6 Further Actions; Best Efforts.

(a) Subject to the terms and conditions of this Agreement, each party shall use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable Laws to consummate the Acquisition and the other transactions contemplated by this Agreement, including preparing and filing as promptly as practicable, all documentation, if any, to effect all necessary filings, notices, petitions, statements, registrations, submissions of information, applications and other documents necessary to consummate the Acquisition and the other transactions contemplated by this Agreement.

(b) In the event that any Proceeding or Order is instituted (or threatened to be instituted) by a Governmental Authority or private party challenging the Acquisition or any other transaction contemplated by this Agreement, or any other agreement contemplated hereby, (i) each of the Buyer, the Company and its Subsidiaries shall cooperate in all respects with each other and use its respective reasonable best efforts to contest and resist any such Proceeding or Order and to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents or restricts consummation of the transactions contemplated by this Agreement, and (ii) each of the Buyer, the Company and its Subsidiaries shall use their respective reasonable best efforts to defend, at its own cost and expense, any action or actions, whether judicial or administrative, in connection with the transactions contemplated by this Agreement.

5.7 Stockholder Approval; Preparation of Proxy Statement.

(a) As promptly as reasonably practicable following the date hereof, the Buyer and the Company shall cooperate in preparing and shall cause to be filed with the SEC mutually acceptable definitive proxy materials (the “Proxy Statement”) relating to the matters to be considered by the stockholders in connection with the Company Special Meeting (as defined below). The Company shall use reasonable best efforts to have the Proxy Statement cleared by the SEC. No filing of, or amendment or supplement to, or correspondence with the SEC or its staff with respect to the Proxy Statement will be made by the Company without providing the Buyer a reasonable opportunity to review and comment thereon. The Company will advise the Buyer, promptly after it receives notice thereof, of any request by the SEC for the amendment of

the Proxy Statement or comments thereon and responses thereto or requests by the SEC for additional information. The Company will cause the final Proxy Statement to be mailed to the Company’s stockholders as promptly as practicable subsequent to its filing with the SEC. If at any time prior to the Company Special Meeting any information relating to the Company or the Buyer, or any of their respective Affiliates, officers or directors, should be discovered by the Company or the Buyer and that should be set forth in an amendment or supplement to the Proxy Statement so that any of such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party which discovers such information shall promptly notify the other parties hereto and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by Law, disseminated to the stockholders of the Company.

(b) As soon as practicable following the execution and delivery of this Agreement, the Company shall duly take all lawful action to set a record date for, duly call, give notice of, convene and hold a special meeting of its stockholders (the “Company Special Meeting”) for the purpose of considering the approval of the Acquisition and the transactions contemplated by this Agreement and such other matters as may in the reasonable judgment of the Company be appropriate for consideration at the Company Special Meeting. The Company’s Board of Directors shall recommend that the stockholders of the Company approve the Acquisition and the consummation of the transactions contemplated by this Agreement and the Company shall include such recommendation in the Proxy Statement and shall not make or effect any Change in Company Recommendation. Unless this Agreement is terminated in accordance with the provisions hereof, this Agreement shall be submitted to the stockholders of the Company at the Company Special Meeting for the purpose of approving the Acquisition and the consummation of the transactions contemplated by this Agreement, and the Company shall use its reasonable best efforts to secure the vote or consent of stockholders required by the DGCL to effect the transactions contemplated by this Agreement.

5.8 Public Announcements. Each of the Company and the Buyer shall use its respective reasonable best efforts to develop a joint communications plan and each party shall use its respective reasonable best efforts (a) to ensure that all press releases and other public statements with respect to the transactions contemplated hereby shall be consistent with such joint communications plan, and (b) unless otherwise required by applicable Law or by obligations pursuant to any listing agreement with, or the rules of, any securities exchange, to consult with each other before issuing any press release or otherwise making any public statement with respect to this Agreement or the transactions contemplated hereby.

5.9 Company Employee Benefits.

(a) Buyer shall, or shall cause the Designated Purchaser to, offer employment, commencing on the Closing Date, to only those US Consumables Employees and Process Business Employees who are actively employed by the Company or an Affiliate in the Consumables Business or the Process Business, respectively on the day immediately preceding the Closing Date (the “Closing Date Employees”), at a wage and salary level that is the same as that provided to such employees of the Company on the day preceding the Closing Date. With respect to the Liabilities relating to the Closing Date Employees who accept the offer of employment described above (the “Transferred Employees”) and arising out of the Company

Plans, Buyer shall, as of the Closing Date, assume only those Liabilities that are both (i) described in Section 2.3(a)(viii) of this Agreement and (ii) directly related to such Transferred Employees’ employment with the Consumables Business or the Process Business, as applicable. In addition to the foregoing, Buyer shall reimburse the Company for all Severance Costs (as such term is hereinafter defined) incurred by the Company in a lump sum within thirty (30) days after Buyer receives from the Company an invoice stating the name of each applicable Closing Date Employee whose employment with the Company was terminated as a result of such employee not accepting the Buyer’s offer of employment, his or her years of service with the Company through such date of termination, his or her annual rate of base salary as in effect immediately prior to the Closing Date, and the total amount of severance paid or payable to such employee by the Company. For purposes of this Agreement, the term “Severance Costs” shall mean, for each Closing Date Employee who does not accept the offer of employment described above and whose employment with the Company or any Affiliate thereof is involuntarily terminated thereby within thirty (30) days after the Closing Date, the amount of severance payments to which such employee would be entitled under the Seller Plan (as such term is defined in Section 5.9(d)) that is a severance plan (as in effect on the date hereof) applicable to such employee, if his employment were involuntarily terminated on the Closing Date; provided, however, that such amount shall only be included in the definition of Severance Costs to the extent that the Company or one of its Affiliates, as applicable, provides such employee with severance payments that are at least equal to such amount. For the avoidance of doubt, Buyer shall not assume any Liabilities relating to change in control agreements or arrangements between the Company or its Affiliates and any Company Employee, or any Liabilities relating to severance and other similar agreements or arrangements between the Company or its Affiliates and any Company Employee who is not a Transferred Employee.

(b) From and after the Closing Date until the first anniversary of the Closing Date, the Buyer shall, or shall cause the Transferred Subsidiaries or Designated Purchaser(s), as applicable, to, provide the Transferred Employees and Transferred Subsidiary Employees who are employed by the Transferred Subsidiary immediately prior to the Closing, for so long as such employees remain so employed by the Buyer or any Subsidiary of the Buyer during such time, health benefits which are no less favorable, in the aggregate, than those provided to employees of a division of the Buyer or any Subsidiary of the Buyer, that is of a size, nature and in a geographic location that is substantially similar to the Company, who are in positions comparable to positions held by such employees with the Buyer or its Subsidiaries from time to time after the Closing Date.

(c) From and after the Closing Date, the Buyer shall, or shall cause the Transferred Subsidiaries or Designated Purchaser, as applicable, to, recognize the prior service with the Company or its Affiliates of each Transferred Employee and Transferred Subsidiary Employee employed as of immediately prior to the Closing Date in connection with all employee benefit plans, programs or policies (including vacation) of the Buyer or any of its Affiliates in which any such employees are eligible to participate following the Closing Date for purposes of eligibility, vesting and levels of vacation and severance benefits (but not for purposes of benefit accruals under any defined benefit pension plan or to the extent that such recognition would result in duplication of benefits). From and after the Closing Date, and to the extent permitted by applicable Law and/or applicable insurance providers, the Buyer will, or will cause the Transferred Subsidiaries or Designated Purchaser, as applicable, to, cause any pre-existing

conditions or limitations and eligibility waiting periods (to the extent that such waiting periods would be inapplicable, taking into account service with the Company and any of its Affiliates), under any group health plans of the Buyer or its Affiliates in which Transferred Employees and Transferred Subsidiary Employees who are employed by the Transferred Subsidiary immediately prior to the Closing, are otherwise to become eligible to participate in after the Closing Date, to be waived with respect to such employees and their eligible dependents. The Buyer shall, or shall cause the Transferred Subsidiaries or Designated Purchaser, as applicable, to, give each Transferred Employee and Transferred Subsidiary Employee credit for any deductibles and annual out-of-pocket limits for medical expenses paid during the applicable plan year in which the Closing occurs under any welfare plans maintained or contributed to by the Company or the Transferred Subsidiaries prior to the Closing in satisfying any deductibles and annual out-of-pocket limits for medical expenses for the same plan year under any welfare plans maintained or contributed to by the Buyer or its Affiliates in which such employees participate during such year.

(d) Except as required by applicable Law, as of the Closing Date the Transferred Employees and Transferred Subsidiary Employees shall cease to accrue further benefits under the employee benefit plans and arrangements maintained by the Company or any of its Affiliates (excluding any such plans maintained solely by any of the Transferred Subsidiaries) (the “Seller Plans”); provided, however, that the Company shall, or shall cause its Affiliates to, take such actions as may be necessary to, effective immediately prior to the Closing Date, cause (i) the US Consumables Employees and the Process Business Employees who become Transferred Employees to be fully vested in any unvested portion of their account balances under any Seller Plans that are defined contribution plans and (ii) all Transferred Subsidiary Employees who are employed by the Transferred Subsidiary immediately prior to the Closing to become fully vested in any unvested benefits under any Seller Plans that are pension plans. From and after the Closing Date, the Company and its Affiliates shall remain solely responsible for any and all Liabilities in respect of the Seller Plans, except as otherwise provided herein. In addition to the foregoing, the Company shall indemnify and hold harmless each Buyer Indemnified Party from and against, and shall reimburse each Buyer Indemnified Party for any and all Losses incurred by the Buyer Indemnified Party in respect of any claim or Liabilities arising from or related to any suit or claim of violation brought against Buyer under WARN and other similar applicable Laws for any actions taken by the Company in connection with, on or prior to the Closing Date with regard to any site of employment, facility, operating unit or employee affected by this Agreement.

(e) Nothing herein is intended to, and shall not be construed to, create any third party beneficiary rights of any kind or nature, including the right of any Company Employee or other individual to seek to enforce any right to compensation, benefits, or any other right or privilege of employment with the Buyer or any of its Affiliates.

5.10 Insurance. To the extent that any insurance policies or binders cover any loss, liability, claim, damage or expense relating to the Consumables Business, the Transferred Process Operations, the Transferred, the Transferred Assets, the Assumed Liabilities or the Transferred Subsidiaries and relating to or arising out of occurrences or wrongful acts prior to the Closing Date and such policies continue after the Closing Date to permit claims to be made thereunder with respect to such occurrences or acts prior to the Closing Date, the Company and

its Affiliates shall cooperate with the Buyer and its Affiliates (including the Transferred Subsidiaries post-Closing) to submit any such claims, including filing and furnishing required notices for the benefit of or on behalf of the Buyer or its Affiliates under such policies or pursuing claims previously made. The Company shall use its reasonable best efforts so that, on and after the Closing Date, the Buyer and its Affiliates (including the Transferred Subsidiaries post-Closing) will be able to have the right to make claims for indemnification to the extent possible under the terms of such policies and, to the extent assignable, shall assign the right to make such claims to the Buyer.

5.11 Reorganization. Notwithstanding anything to the contrary contained in this Article V or any other provision of this Agreement, it is the explicit intent of the Buyer and the Company that the Company and its Subsidiaries shall consummate at or prior to the Closing certain transactions, including asset transfers, to ensure that the Transferred Subsidiaries only own assets used or held for use principally in the conduct or operation of the Consumables Business or the Transferred Process Operations or that otherwise constitute Transferred Assets, and are subject only to Liabilities that fall within the definition of Assumed Liabilities, in furtherance of the transactions contemplated hereby and as set forth in Section 5.11 of the Company Disclosure Schedule (the “Reorganization”), and the Company agrees to cause the Reorganization to occur prior to the Closing. The Company shall provide the Buyer copies of, and the opportunity to review and comment on, the documents relating to the Reorganization prior to their execution and shall not make any such transfers or take other similar actions without the prior written consent of the Buyer.

5.12 Certain Notices. From and after the date of this Agreement until the Closing, the Company and the Buyer shall promptly notify each other orally and in writing of (a) any notice or other communication from any Person alleging that the Consent of such Person is or may be required in connection with the Acquisition and the other transactions contemplated by this Agreement, (b) any Proceedings commenced or, to the Knowledge of the Company or the Knowledge of the Buyer, as the case may be, threatened against, relating to or involving or otherwise affecting such party or any of its Subsidiaries that, if pending on the date of this Agreement, would have been required to be disclosed pursuant to Article IV, or that relate to the transactions contemplated by this Agreement, (c) in the case of the Company, any customer, supplier, vendor or distributor threatening any material modification or change in, or termination of, its business relationship with the Consumables Business or the Process Business and (d) in the case of the Company, any fact, event, change or circumstance known to it that (i) individually or taken together with all other facts, events, changes and circumstances known to it, has had, or would reasonably be expected to have, a Material Adverse Effect or (ii) would result in, or would reasonably be expected to result in, any of the conditions to the Acquisition set forth in Article VIII not being satisfied or which would adversely affect, in any material respect, the ability of the parties to consummate the Acquisition and the other transactions contemplated by this Agreement on a timely basis.

5.13 Certain Intellectual Property Covenants.

(a) The Company shall and shall cause its Subsidiaries to, at their expense, take such actions prior to and after the Closing as reasonably required, or as requested by Buyer, to duly execute, deliver and file as of the Closing Date or as soon thereafter as practicable all instruments and documents necessary to ensure that the records and registrations of all

Intellectual Property used or held for use in the conduct or operation of the Acquired Businesses, in the United States Patent and Trademark Office or the United States Copyright Office and all counterpart or similar agencies wherever such Intellectual Property is registered, correctly reflect all transactions affecting the ownership by Buyer of such Intellectual Property.

(b) Buyer hereby grants the Company for a period of up to three years following the Closing a non-exclusive, worldwide, royalty free and fully paid-up, non-assignable and sublicensable only to Affiliates of the Company, license to use the name “ARGONAUT TECHNOLOGIES, INC.” in connection with the sale and offering for sale of products and the provision of services by the Company or its Affiliates solely to the extent that such name was used prior to the Closing.

5.14 WARN. The Company shall not, at any time within the 60-day period prior to the Closing Date, effectuate a “plant closing” or “mass layoff,” as those terms are defined in the WARN or any other similar triggering event under similar applicable Laws, affecting in whole or in part any site of employment, facility or operating unit of the Consumables Business or the Process Business.

5.15 Intercompany Accounts. The Company shall take any and all actions necessary so that, as of the Closing, there will not be outstanding any Liabilities, and there shall have been settled all intercompany accounts, between the Company and its Affiliates (other than the Transferred Subsidiaries), on the one hand, and the Acquired Businesses or the Transferred Subsidiaries, on the other hand.

5.16 Confidentiality. The Company recognizes that by reason of its ownership of the Consumables Business, the Process Business, the Transferred Assets and the Transferred Shares, it and its Affiliates have acquired confidential information and trade secrets concerning the Consumables Business and the Process Business, the use or disclosure of which could cause the Buyer or its Affiliates substantial loss and damages that could not be readily calculated and for which no remedy at law would be adequate. Accordingly, the Company covenants and agrees with the Buyer that the Company and its Affiliates will not at any time, except in performance of the Company’s obligations to the Buyer or with the prior written consent of the Buyer, directly or indirectly, disclose any proprietary, secret or confidential information relating to the Consumables Business or the Process Business that any such Person may learn or has learned by reason of its ownership of the Consumables Business, the Process Business, the Transferred Assets and the Transferred Shares, unless (i) such information becomes known to the public generally through no fault of the Company or of its Affiliates or (ii) disclosure is required in the opinion of its independent counsel, by applicable Law. The parties hereto agree that the covenant contained in this Section 5.16 imposes a reasonable restraint on the Company, its Affiliates and its employees.

5.17 Successors.

(a) In the event that the Company (or any of its respective successors or assigns) shall (i) consolidate or merge with any other Person and shall not be the continuing or surviving corporation or entity in such consolidation or merger, (ii) transfer all or substantially all of its properties and assets to any other person, or (iii) decide to dissolve or liquidate, or adopt a plan of dissolution or liquidation, then in each case proper provision shall be made so that the

continuing or surviving corporation or entity (or its successors or assigns, if applicable), or transferee of such assets, or such liquidating trust or other agent, as the case may be, shall expressly assume all of the Company’s obligations under this Agreement, including pursuant to Articles II and X. Prior to any such transaction, the Company shall notify the Buyer of any transaction that would trigger the terms of this Section 5.17 and the terms thereof, including the identity of the purchaser.

(b) In the event that the Buyer (or any of its respective successors or assigns) shall consolidate or merge with any other Person and shall not be the continuing or surviving corporation or entity in such consolidation or merger, or transfers all or substantially all of its properties and assets to any other person, then in each case proper provision shall be made so that the continuing or surviving corporation or entity (or its successors or assigns, if applicable), or transferee of such assets, as the case may be, shall expressly assume all of the Buyer’s obligations under this Agreement, including pursuant to Articles II and X.

ARTICLE VI

TAX MATTERS

6.1 Control of Tax Audits. The Company shall have the right to represent the interests of the Transferred Subsidiaries in any Tax audit or administrative or court proceeding (a “Tax Proceeding”) relating to any Tax covered by Sections 10.1(a)(iv) and (vi) and to employ counsel of its choice; provided that if the results of such Tax audit or proceeding could reasonably be expected to have a material adverse effect on the Buyer, any of the Buyer’s Affiliates or any of the Transferred Subsidiaries for any Post-Closing Tax Period, then the Company and the Buyer shall jointly control the defense and settlement of any such Tax audit or proceeding and each party shall cooperate with the other party at its own expense and there shall be no settlement or closing or other agreement with respect thereto without the consent of the other party, which consent will not be unreasonably withheld or delayed. The Company shall promptly notify the Buyer if it decides not to control the defense or settlement of any such Tax audit or administrative or court proceeding and the Buyer thereupon shall be permitted to defend and settle such Tax audit or proceeding. With respect to any Tax Proceeding of any of the Transferred Subsidiaries relating to a Straddle Period, the Company and the Buyer shall jointly control the defense and settlement of any such Tax audit or proceeding and each party shall cooperate with the other party at its own expense and there shall be no settlement or closing or other agreement with respect thereto without the consent of the other party, which consent will not be unreasonably withheld or delayed. Notwithstanding the foregoing, the Company shall not be entitled to settle the UK Tax Proceeding without the prior written consent of the Buyer if the amount of such settlement would exceed (a) the amount of Escrow Funds available at such time to satisfy such claim, plus (b) the amount tendered by the Company to the Buyer to satisfy its indemnification obligation under this Agreement with respect to such proposed settlement.

6.2 Tax Returns. The Buyer shall, or cause the Transferred Subsidiaries to, properly prepare or cause to be properly prepared, and shall timely file or cause to be timely filed, all Tax Returns of the Transferred Subsidiaries that are required to be filed after the

Closing Date. Such Tax Returns shall be prepared in a manner consistent with past practices, unless such past practices are not in accordance with applicable law. The Company shall pay all Taxes shown as due and owing on such Tax Returns or otherwise levied or assessed upon any of the Transferred Subsidiaries to the extent such Taxes relate to a Pre-Closing Tax Period.

6.3 Cooperation; Other Tax Matters. The Company and the Buyer shall cooperate fully with each other in connection with the preparation and timely filing of any Tax Returns required to be prepared and filed by the Buyer or the Company, or in connection with the preparation or filing of any election, claim for refund, consent or certification. For the avoidance of doubt, with respect to the Transferred Subsidiaries, all Tax Returns and other records and information relating to Taxes shall be retained by the Transferred Subsidiaries and constitute part of the Transferred Assets and shall be transferred to the Buyer through the sale of the Transferred Shares pursuant to Section 2.1; provided, however, the Buyer shall provide the Company with copies of such Tax Returns upon reasonable request. The Company will provide copies of all Tax Returns of the Company that are reasonably requested by the Buyer or its Subsidiaries in connection with a Tax Proceeding.

6.4 Transfer Taxes. The Company and the Buyer shall share equally and be responsible for the timely payment of (on an after-tax basis) all sales (including bulk sales), use, value added, documentary, stamp, gross receipts, registration, transfer, conveyance, excise, recording, license, stock transfer stamps, UK Stamp Duty Land Tax and other similar Taxes and fees (“Transfer Costs”) arising out of or in connection with or attributable to the transactions effected pursuant to this Agreement. The Company and the Buyer shall use their respective commercially reasonable efforts to deliver certain of the Transferred Assets, as appropriate, through an electronic delivery or in such other manner reasonable calculated and legally permitted, and take all other commercially reasonable actions necessary, to minimize or avoid the incurrence of Transfer Costs.

6.5 Straddle Periods. Taxes attributable to Straddle Periods (including any Taxes resulting from a Tax audit or administrative or court proceeding) shall be apportioned to the period ending on the Closing Date and to the period beginning on the day after the Closing Date by means of a closing of the books and records of the Company as of the close of business on the Closing Date and, to the extent not susceptible to such allocation, by apportionment on the basis of elapsed days unless such Tax is transaction based (such as sales, transfer and other similar Taxes) in which case such Tax shall be apportioned to the period in which the related transaction occurred/occurs.

6.6 Proration of Taxes. Real and personal property Taxes and ad valorem Taxes (and related Tax refunds or credits) (collectively, “Periodic Taxes”) relating to the Transferred Assets shall be prorated between the Company and the Buyer for any Straddle Period. Periodic Taxes relating to the Transferred Assets and attributable to Straddle Periods shall be prorated between the Buyer and the Company based on the relative periods such assets of the Company were owned by each respective party during the fiscal period of the taxing jurisdiction for which such Taxes were imposed by such jurisdiction (as such fiscal period is or may be reflected on the ▇▇▇▇ rendered by such taxing jurisdiction). On the Closing Date, the Buyer and the Company shall pay or be reimbursed, on this prorated basis, for Periodic Taxes relating to the Transferred Assets that have been paid prior to the Closing Date. The Buyer or the Company shall promptly forward an invoice to the other party for its reimbursable pro rata share, if any, of any Periodic Taxes relating to the Transferred Assets paid after the Closing Date.

6.7 Section 338 Elections.

In no event shall any Buyer Indemnified Party or Company Indemnified Party, as applicable, be entitled to indemnification in respect of Liabilities, Buyer Losses or Company Losses, as the case may be, for which such Buyer Indemnified Party or Company Indemnified Party, as the case may be, has already been compensated pursuant to Section 3.3 or this Article X; provided that such restriction on indemnification shall only apply to the extent that such Buyer Indemnified Party or Company Indemnified Party, as the case may be, has actually received payment in respect of such Liabilities, Buyer Losses or Company Losses, as applicable.

10.3 Notice of Indemnity Claims. If any Buyer Indemnified Party or Company Indemnified Party entitled to or seeking indemnification hereunder (an “Indemnified Party”) (i) determines that any event, occurrence, fact, condition or claim has given or could give rise to any Buyer Losses or Company Losses, as applicable, for which such Indemnified Party is or may be entitled to, or may seek, indemnification under this Agreement, (ii) otherwise identifies an event, occurrence, fact, condition or claim giving rise (or which may give rise) to a right of indemnification hereunder in favor of such Indemnified Party, or (iii) with respect to any Third Party Claim (as defined herein), becomes aware of the assertion of any claim or of the commencement of any Proceeding at law or in equity (any of the foregoing, an “Indemnity Claim”), such Indemnified Party shall promptly notify the party obligated to provide indemnification or from whom indemnification is being or will be sought (the “Indemnifying Party”) in writing of such Indemnity Claim (a “Claim Notice”) describing the facts giving rise to the claim for indemnification under this Agreement and shall include in such Claim Notice (if then known) the amount or the method of computation of the amount of such claim and a reference to the provision of this Agreement or any other agreement, document or instrument executed hereunder or in connection with this Agreement upon which such claim is based; provided, however, that the failure of any Indemnified Party to give timely notice thereof shall not affect any of its rights to indemnification hereunder nor relieve the Indemnifying Party from any of its indemnification obligations hereunder, except to the extent the Indemnifying Party is materially prejudiced by such failure.

10.4 Indemnification Procedures. Any obligation to provide indemnification hereunder with respect to any Proceeding at law or in equity by or against any third party, including any Governmental Authority (a “Third Party Claim”), except with respect to Tax Proceedings, which shall be governed by Article VI, shall be subject to the following terms and conditions:

(a) Within ten (10) days after receipt of a Claim Notice, the Indemnifying Party shall give written notice to the Indemnified Party stating whether it disputes the Indemnity Claim and whether it will defend against such Indemnity Claim. The Indemnifying Party shall be

entitled, at its sole cost and expense, subject to Section 10.5, to assume and control the defense, compromise, settlement and investigation of such Indemnity Claim, including the management of any Proceeding relating thereto, and to employ and engage counsel reasonably acceptable to the Indemnified Party. The Indemnified Party shall at all times have the right to fully participate in the defense of an Indemnity Claim at its own cost and expense directly or through counsel; provided, however, that if the named parties to a Proceeding include both the Indemnifying Party and the Indemnified Party and the Indemnified Party has been advised by counsel that (i) representation of both parties by the same counsel would be inappropriate under applicable standards of professional conduct or (ii) there may be one or more legal or equitable defenses available to it that are different from or additional to those available to the Indemnifying Party, then, in either case, the Indemnified Party shall be entitled to retain its own counsel at the cost and expense of the Indemnifying Party (except that the Indemnifying Party shall not be obligated to pay the fees and expenses of more than one separate counsel for all Indemnified Parties, taken together). Notwithstanding the foregoing, the Indemnified Party, during the period the Indemnifying Party is determining whether to elect to assume the defense of a matter covered by this Section 10.4, may take such reasonable actions as it deems necessary to preserve any and all rights with respect to the matter, without such actions being construed as a waiver of the Indemnified Party’s rights to defense and indemnification under this Agreement.

(b) If the Indemnifying Party exercises the right to undertake the defense and investigation of any such Indemnity Claim as provided in Section 10.4(a), then (i) the Indemnified Party agrees to cooperate with the Indemnifying Party in such efforts and make available to the Indemnifying Party all witnesses, records, materials and information in the Indemnified Party’s possession, under its control or to which it may have access as may be reasonably requested by the Indemnifying Party, and (ii) the Indemnifying Party will keep the Indemnified Party reasonably informed of the progress of the defense of any such Indemnity Claim. If the Indemnifying Party fails to undertake the defense and investigation of any such Indemnity Claim as provided in Section 10.4(a), including conducting a good faith and diligent defense, then (i) the Indemnified Party against which such Indemnity Claim has been asserted shall have the right to undertake the defense, compromise, settlement and investigation of such Indemnity Claim on behalf of, and at the cost and expense of and for the account and risk of, the Indemnifying Party, (ii) the Indemnifying Party agrees to cooperate with the Indemnified Party in such efforts and make available to the Indemnified Party all witnesses, records, materials and information in the Indemnifying Party’s possession, under its control or to which it may have access as may be reasonably requested by the Indemnified Party, and (iii) the Indemnified Party will keep the Indemnifying Party reasonably informed of the progress of the defense of any such Indemnity Claim.

10.5 Settlement of Indemnity Claims. The Indemnifying Party shall not, without the prior written consent of the Indemnified Party, (a) settle or compromise any Indemnity Claim or consent to the entry of any final judgment that does not include as an unconditional term thereof the delivery by the claimant or plaintiff of a written release or releases from all liability in respect of such Indemnity Claim of all Indemnified Parties affected by such Indemnity Claim, or (b) settle or compromise any Indemnity Claim if the settlement imposes equitable remedies or material obligations on the Indemnified Party other than financial obligations for which such Indemnified Party shall be indemnified hereunder. Except in the event the Indemnified Party has assumed the defense of the Indemnified Claim pursuant to Section 10.4(b),

the Indemnified Party shall not, without the prior written consent of the Indemnifying Party, settle or compromise any Indemnity Claim or consent to the entry of any final judgment with respect to an Indemnity Claim.

10.6 Survival. All covenants and agreement of the parties made in this Agreement shall survive the Closing Date unless otherwise expressly provided herein. The representations and warranties of the Company and the Buyer contained in this Agreement shall survive the Closing Date for a period of twelve (12) months following the Closing Date, notwithstanding any investigation at any time made by or on behalf of the party, except (a) the representations and warranties of the Company contained in Sections 4.1(a), (b), (c), (j), and (r) and the representations and warranties of the Buyer contained in Sections 4.2(a), (b) and (d) shall survive indefinitely and (b) the representations and warranties of the Company contained in Sections 4.1(k) shall survive until ninety (90) days following the expiration of the applicable statue of limitations or statutory tax assessment period (including all periods of extension, whether automatic or permissive). If any Claim Notice for indemnification under Section 10.1(a) or 10.1(b) shall have been given within the applicable survival period, the representations and warranties that are the subject of such indemnification claim shall survive until such time as such claim is finally resolved.

10.7 Treatment of Indemnification Payments. Each of the Buyer and the Company agrees to treat any payment made under this Article X as an adjustment to the Purchase Price. If, notwithstanding such treatment by the parties, any indemnity payment is determined to be taxable income rather than an adjustment to the Purchase Price by any taxing authority, then the indemnifying party shall indemnify the indemnified party for any Taxes imposed on the indemnified party or by reason of the receipt of such indemnity payment (including any payments under this Section 10.7).

10.8 Remedies Exclusive. Except for any equitable relief, including injunctive relief or specific performance, to which any party to this Agreement may be entitled, the indemnification contemplated by this Article X shall be the sole and exclusive remedy of any Buyer Indemnified Party or Company Indemnified Party with respect to this Agreement or the transactions contemplated hereby or thereby, except with respect to any damages incurred by any party as a result of, or in connection with any, fraud or willful breach on the part of the other party; provided, however, that nothing in this Section 10.8 shall limit the rights or remedies expressly provided for in this Agreement or any other instrument delivered hereunder or the rights or remedies which, as a matter of applicable Law or public policy, cannot be limited or waived.

11.2 Counterparts; Facsimile Signature. This Agreement may be executed in any number of counterparts, each of which shall be considered one and the same agreement and shall become effective when all counterparts have been signed by each of the parties and delivered to the other party, it being understood that the parties need not sign the same counterpart. Any party may execute this Agreement by facsimile signature, and the other parties will be entitled to rely on such facsimile signature as conclusive evidence that this Agreement has been duly executed by such party.

11.3 Bulk Sales. The parties hereto agree to waive compliance with the provisions of the Laws of any jurisdiction relating to a bulk sale or transfer of assets that may be applicable to the transactions contemplated by this Agreement.

11.4 Further Assurances. From time to time after the Closing and without further consideration, the Company shall, and shall cause its Subsidiaries to, execute, acknowledge and deliver such documents and instruments of conveyance, assignment, transfer and delivery and take or cause to be taken such other actions as the Buyer may reasonably request in order to carry out the purpose and intention of this Agreement, including to consummate more effectively the purchase, sale, conveyance, assignment, transfer and delivery of the Transferred Shares and the Transferred Assets as contemplated by this Agreement, to vest in the Buyer and/or the Designated Purchaser title to the Transferred Shares and the Transferred Assets or to enable the Buyer and/or the Designated Purchaser to protect, exercise and enjoy all rights and benefits of the Company or its Subsidiaries with respect thereto and as otherwise appropriate to consummate the transactions contemplated by this Agreement.

11.5 Entire Agreement. This Agreement (including the documents and the instruments referred to herein) and the Escrow Agreement constitutes the entire agreement among all the parties hereto and terminates and supersedes all prior agreements and understandings, oral and written, among all the parties hereto with respect to the subject matter hereof and thereof, other than the Confidentiality Agreement which shall survive the execution and delivery of this Agreement as provided for herein.

11.6 No Third-Party Beneficiaries. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and assigns. Nothing in this Agreement, expressed or implied, is intended to or shall confer on any Person other than the parties hereto or their respective successors and assigns, any rights, remedies or Liabilities under or by reason of this Agreement.

11.7 Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto, in whole or in part (whether by operation of law or otherwise), without the prior written consent of the other parties, and any attempt to make any such assignment without such consent shall be null and void; provided, however, that the Buyer may assign in writing its rights and obligations, in whole or in part, to one or more of its wholly-owned Subsidiaries, but the Buyer shall remain jointly and severally liable with any such assignee(s) with respect to all obligations of the Buyer hereunder.

11.8 Amendment and Modification; Waiver. This Agreement may be amended, modified and supplemented by the parties hereto, by action taken or authorized by their respective Boards of Directors, at any time before or after the Stockholder Approval, but, after any such approval, no amendment shall be made which by Law requires further approval by such stockholders without such further approval. This Agreement may not be amended, except by an instrument in writing signed on behalf of each of the parties hereto. At any time prior to the Closing, the parties hereto, by action taken or authorized by their respective Boards of Directors, may, to the extent legally permitted, (a) extend the time for the performance of any of

the obligations or other acts of any other party hereto, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered hereto and (c) waive compliance with any of the agreements or conditions contained herein. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party. The failure of a party to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights.

11.9 Enforcement; Jurisdiction. The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in any federal court or state court sitting in the State of Delaware, this being in addition to any other remedy to which they are entitled at law or in equity subject to the terms hereof. In addition, each of the parties hereto (a) hereby irrevocably agrees that any legal action or proceeding with respect to this Agreement or for recognition and enforcement of any judgment in respect hereof brought by another party hereto or its successors or assigns may be brought and determined in the Court of Chancery of the State of Delaware or the federal courts located in the State of Delaware, and each party hereto hereby irrevocably submits with regard to any such action or proceeding for itself and in respect of its property, generally and unconditionally, to the exclusive jurisdiction of the aforesaid courts, and (b) irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement, (i) any claim that it is not personally subject to the jurisdiction of the above-named courts for any reason other than the failure to lawfully serve process, (ii) that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise), and (iii) to the fullest extent permitted by applicable Law, that (A) the suit, action or proceeding in any such court is brought in an inconvenient forum, (B) the venue of such suit, action or proceeding is improper and (C) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

11.10 Waiver of Jury Trial. EACH OF THE PARTIES TO THIS AGREEMENT HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ALL RIGHTS TO A 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 ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY.

11.11 Costs and Expenses. Regardless of whether the transactions contemplated by this Agreement are consummated and except as otherwise provided in this Agreement, the Company, on the one hand, and the Buyer, on the other hand, will each bear their own costs and expenses (including attorneys’ fees and costs) incurred in connection with this Agreement and the transactions contemplated by this Agreement.

11.12 Setoff. The Company agrees that the Buyer and its Subsidiaries may setoff against any amounts due and owing to the Company or any of its Subsidiaries hereunder any amounts due to the Buyer or its Subsidiaries under this Agreement. Each of the Company and its Subsidiaries hereby waives any right of setoff it may have or to which it may be entitled

under this Agreement from time to time against Buyer and its Subsidiaries and expressly waives the right to cause or instruct the escrow agent to do the same with respect to any payment from the Escrow Funds.

11.13 Casualty Losses. If there shall have been suffered between the date of this Agreement and the Closing Date any casualty or loss relating to the Transferred Assets or any asset of the Transferred Subsidiaries, then at the Closing all claims to insurance proceeds or other rights of the Company or any of its Subsidiaries against third parties relating from such casualty or loss shall (to the extent assignable) be separately assigned by the Company or its Subsidiaries to the Buyer and/or the Designated Purchaser. To the extent not so assignable, the Company shall, and shall cause its Subsidiaries to, remit all proceeds received from insurers or third parties in respect of such claims to the Buyer.

11.14 Mutual Drafting. The parties hereto have been represented by counsel who have carefully negotiated the provisions hereof. As a consequence, the parties do not intend that the presumptions of any laws or rules relating to the interpretation of contracts against the drafter of any particular clause should be applied to this Agreement and therefore waive their effects. The provisions of this Agreement shall be interpreted in a reasonable manner to effect the intent of the parties.

11.15 Governing Law. This Agreement shall be governed by, and construed and interpreted in accordance with, the laws of the State of Delaware, without giving effect to the principles of conflict of laws thereof.

11.16 Disclosure Schedules. Each disclosure set forth in the Company Disclosure Schedule or Buyer Disclosure Schedule shall be deemed disclosed for purposes of, and shall qualify and be treated as an exception to, only the specific section of this Agreement specified therefor, except to the extent that disclosure in one specific section of the Company Disclosure Schedule or Buyer Disclosure Schedule, as the case may be, is specifically referred to in another specific section of the Company Disclosure Schedule or Buyer Disclosure Schedule, as applicable, or by appropriate cross-reference and except to that it would be reasonably apparent that a reference in one specific section in the Company Disclosure Schedule or Buyer Disclosure Schedule, as the case may be, also relates to another specific section of the Company Disclosure Schedule or Buyer Disclosure Schedule.

11.17 Severability. Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability and shall not render invalid or unenforceable the remaining terms and provisions of this Agreement or affect the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable.

ESCROW AGREEMENT (the “Agreement”) entered into as of the ^th day of March, 2005, by and among Biotage AB, a corporation organized under the laws of Sweden (“Buyer”), Argonaut Technologies, Inc., a Delaware corporation (the “Company”), and [ ], as escrow agent (the “Escrow Agent”).

WHEREAS, pursuant to a Sale and Asset Purchase Agreement dated as of February , 2005 (the “Purchase Agreement”), between Buyer and the Company, Buyer will acquire from the Company certain assets and shares and assume certain liabilities of the Company;

WHEREAS, the Purchase Agreement contemplates the due execution and delivery of this Agreement at, and as a condition to, the Closing;

WHEREAS, the Company has agreed to indemnify Buyer against breaches of the representations, warranties and covenants made by the Company in the Purchase Agreement and against certain other matters as specified in Articles III, VI and X of the Purchase Agreement;

WHEREAS, to secure partially the payment of the Company’s indemnification obligations and other obligations pursuant to Articles III, VI and X of the Purchase Agreement, if any, Two Million Dollars ($2,000,000) of the consideration to be received by the Company pursuant to the Purchase Agreement is being deposited, pursuant to Section 3.2(a) of the Purchase Agreement, in escrow to be held by the Escrow Agent as hereinafter provided; and

WHEREAS, the Escrow Agent is willing to act as escrow agent on the terms and conditions hereinafter set forth;

NOW, THEREFORE, in consideration of the mutual promises and covenants contained herein, the parties hereby agree as follows:

1. Defined Terms. Unless otherwise indicated, all capitalized terms used herein shall have the respective meanings attributed to them in the Purchase Agreement.

2. Establishment of Escrow. Pursuant to Section 3.2(a) of the Purchase Agreement, on the Closing Date, the Buyer shall deliver to the Escrow Agent Two Million Dollars ($2,000,000) (the “Closing Escrow”), and the Escrow Agent shall deposit the Closing Escrow into an escrow account (the “Escrow Account”). All amounts held in the Escrow Account shall be held, invested and distributed pursuant to the terms and conditions of this Agreement. No part of the Escrow Account or any interest accrued thereon may be withdrawn from the escrow established hereunder (the “Escrow”) without the prior written consent of the Company and the Buyer, except as expressly provided otherwise in Section 4 of this Agreement. The Escrow Agent shall hold all amounts in the Escrow Account in a separate account, apart from any other funds or accounts of the Escrow Agent or any other person. The Escrow Agent shall keep an accurate record of all transactions with respect to such amount.

3. Administration of Escrow.

3.1 Any monies held in the Escrow Account shall be invested and reinvested by the Escrow Agent as specifically directed in writing by the Company, to the extent permitted by law, in (a) direct obligations issued or guaranteed by the United States of America or any agency or instrumentality thereof; (b) obligations (including certificates of deposit and bankers’ acceptances) of banks and savings and loan associations which at the date of their last public reporting had total assets in excess of $500 million; and (c) mutual funds sponsored by the Escrow Agent investing exclusively in the securities described in the foregoing clauses (a) and (b) (the “Mutual Funds”). If the Company does not provide directions to the Escrow Agent for any investment or reinvestment of monies held in the Escrow Account, such monies shall be invested in the Mutual Funds. Neither the Escrow Agent, the Buyer nor the Company shall be liable or responsible for any loss resulting from any investment or reinvestment made pursuant to this Section 3. The Escrow Account shall be increased from time to time by any and all interest accrued and paid or dividends or similar return received by the Escrow Agent thereon (“Interest”) after payment of expenses incurred in connection with the investment, reinvestment or sale thereof, pursuant to this Section 3.1 and shall be distributed in accordance with this Agreement.

4. Claims by the Buyer.

4.1 Direct Claim Notices. If the Buyer wishes to make a claim for losses under this Agreement for any amount that it is entitled to receive under Article X of the Purchase Agreement (the “Direct Claim Payment”), the Buyer shall deliver to the Escrow Agent (with a copy to the Company) a written notice signed by the Buyer (i) specifying (x) in reasonable detail the amount of the Direct Claim Payment sought and nature of the Direct Claim or (y) a reasonable estimate of the amount of losses which the Buyer expect to incur with respect to any matter for which the Buyer may be entitled to submit a claim notice under Section 10.3 of the Purchase Agreement (in either case, a “Direct Claim Notice”) and (ii) that the Direct Claim Payment specified in clause (i) is the Buyer’s good faith estimate of the amount that the Buyer is entitled to receive under Article X of the Purchase Agreement. The Direct Claim Notice shall clearly state that it is a “Direct Claim Notice.” Any Direct Claim Notice to be delivered for a claim against the Closing Escrow must be given by the Buyer on or prior to the date that is three business days after the one-year anniversary of the Closing Date (the “Initial Closing Escrow Termination Date”) and must relate to a claim which arose prior to such anniversary; provided, however, that if the UK Tax Proceeding is not resolved by the Initial Closing Escrow Termination Date, such period shall be extended for claims in respect of the UK Tax Liability as provided in Section 3.2(a) of the Purchase Agreement (the date, as so extended pursuant to such Section 3.2(a), shall be the “Initial Closing Escrow Termination Date”).

4.2 If the time period required to resolve the claim underlying any Direct Claim Notice (including the time required for the Independent Accounting Firm to determine the

amount to be paid or reserved from the Closing Escrow in respect of any Direct Claim Notice) extends beyond the Initial Closing Escrow Termination Date, the Escrow Agent shall retain the aggregate amount shown in such Direct Claims Notice(s), including Interest thereon, and extend the Initial Closing Escrow Termination Date by the period of time remaining until all such remaining claims are finally resolved (the “Extended Escrow Termination Date”). Funds in the Escrow Account in excess of the amounts shown in all such remaining Direct Claim Notices on the Initial Closing Escrow Termination Date (an “Overage”) including Interest thereon shall be paid to the Company within three business days after the Initial Closing Escrow Termination Date.

4.3 The Company shall have 10 business days to provide written notice of objection to the Purchaser and the Escrow Agent of any Direct Claim Notice, specifying in reasonable detail any items disputed. After receipt of any such dispute notice, the parties agree to negotiate in good faith to resolve such dispute. If any such dispute cannot be resolved by the parties within thirty days, the parties agree to appoint the Independent Accounting Firm (or if the Independent Accounting Firm is unable to resolve such dispute, another mutually acceptable third party) to settle such dispute in accordance with Section 7(d). If the Company does not provide any such written notice of objection pursuant to this Section 4.3, the Escrow Agent shall promptly pay such amount including any Interest thereon to the Buyer from the Escrow Account and deliver a copy of the Direct Claim Notice to the Company; provided that in the case of a Direct Claim Notice provided pursuant to Section 4.1(i)(y), the Escrow Agent shall pay such amount as is finally resolved to be the amount of losses actually incurred by the Buyer.

4.4 Each of the Buyer and the Company hereby agrees that it will deliver notices to the Escrow Agent only in accordance with Section 16 hereof.

5. Release and Termination of Escrow Account. On a date not later than three business days after the Initial Closing Escrow Termination Date or the Extended Escrow Termination Date, if any, the Escrow Agent shall make a cash payment to the Company from the Escrow Account of an amount equal to all funds remaining in the Escrow Account including Interest thereon, less any amounts that are paid to the Buyer as a result of each such Direct Claim Notice.

6. Fees of Escrow Agent. All fees and costs of the Escrow Agent (including reasonable attorneys’ fees) shall be paid out of the Escrow Account; provided, however, any such fees in excess of $15,000 annually (the “Fee Cap”) shall be paid by the Company. The Escrow Agent shall send copies of periodic invoices for fees and costs to the Company and the Buyer, and the Company shall pay the amount of any invoice reflecting fees in excess of the Fee Cap within 30 days of receipt of such invoice. In the event any amounts owed to the Escrow Agent remain unpaid upon the expiration of such 30-day period, the Company and the Buyer hereby authorize the Escrow Agent to disburse such unpaid fees and costs to itself from the Escrow Account. If such amounts are deducted from the Escrow Account, the Company shall promptly make such adjusting payments to the Escrow Account as shall be necessary so that it pays all such fees and costs. The Escrow Agent shall have no liability for any such fees and costs unless arising from its own bad faith, gross negligence or willful misconduct.

7. Responsibilities and Liabilities of the Escrow Agent.

(a) The Escrow Agent shall deal with the Escrow Account and any interest accrued thereon only in accordance with (a) this Agreement and, to the extent referred to herein, the Purchase Agreement or (b) written instructions given in conformity with this agreement. The Escrow Agent assumes no liabilities except those expressed in this Agreement and shall have no responsibility or liability to any person with respect to any action taken, suffered or omitted to be taken by it in good faith under this Agreement, or for any mistake of fact or law, or for anything that it may do or refrain from doing in connection herewith, except to the extent that such actions constitute bad faith, gross negligence or willful misconduct.

(b) The Escrow Agent shall be protected in acting upon any notice, request, certificate, approval, consent, or other document delivery of which complies with Section 16 and that the Escrow Agent reasonably believes to be genuine and to be signed by the proper party or parties. The Escrow Agent may assume that any person purporting to give notice, receipt or advice or make any statement or execute any document with the provisions hereof has been duly authorized to do so. The Escrow Agent may act in reliance upon the advice of counsel satisfactory to it in reference to any matter in connection with this Agreement and shall not incur any liability for any action taken in good faith in accordance with such advice.

(c) The Escrow Agent shall be deemed conclusively to have given and delivered any notice required to be given or delivered hereunder if the same is in writing, signed by any of the Escrow Agent’s authorized officers and mailed by registered or certified mail, addressed to each of the parties at its address set forth herein, or otherwise is in accordance with Section 16.

(d) In the event of any disagreement between the other parties hereto resulting in adverse claims or demands being made in connection with the Escrow Account (which disagreement is not resolved within 30 days), or in the event that the Escrow Agent in good faith is in doubt as to what action it should take hereunder, (i) the Escrow Agent shall be entitled, without liability on its part, to refrain from making any disbursement or taking any further action, and (ii) the parties shall appoint the Independent Accounting Firm (as such term is defined in the Purchase Agreement) to resolve such disagreement, which Independent Accounting Firm shall settle such disagreement in its sole discretion. The fees and expenses of such Independent Accounting Firm shall be allocated between the Buyer and the Company in such manner that the Buyer shall be responsible for that portion of the fees and expenses equal to such fees and expenses multiplied by a faction the numerator of which is the aggregate dollar value of disputed items submitted to the Independent Accounting Firm that are resolved against the Buyer (as finally determined by the Independent Accounting Firm) and the denominator of which is the total dollar value of the disputed items so submitted, and the Company shall be responsible for the remainder of such fees and expenses. The determination of the Independent Accounting Firm shall be set forth in writing (such determination to include a work sheet setting forth all material calculations used in arriving at such determination and to be based solely on information provided to the Independent Accounting Firm by the Buyer and the Company) delivered to each of the Buyer and the Company and shall be final, binding and non-appealable on the parties hereto. The Escrow Agent shall retain any disputed amounts in the Escrow Fund

until the Escrow Agent shall have received either the final decision of the Independent Accounting Firm as described above or written instructions jointly executed by the Buyer and the Company directing delivery of the amounts of the Escrow Account in dispute, in which event the Escrow Agent shall deliver the amounts of the Escrow Account in dispute in accordance with such order and instructions. The Escrow Agent shall act on such order without further questions. In any event, the Escrow Agent shall not be liable by reason of such action or omission to act to any of the parties hereto or to any other person, firm, association, or corporation, even if thereafter any such order, judgment, decree or levy be reversed, modified, annulled, set aside, or vacated.

(e) The Escrow Agent shall have no responsibility for and makes no representation as to the validity, genuineness or sufficiency of this Agreement or the value, validity or genuineness of any check for payment of money deposited with the Escrow Agent under this Agreement.

(f) The Buyer and the Company hereby appoint the Escrow Agent as their attorney-in-fact for the purposes of causing effective transfers of property from the Escrow Account in accordance with the terms of this Agreement.

(g) The Escrow Agent or any successor Escrow Agent hereunder may resign hereunder (i) at any time, with the consent of the Buyer and the Company and the appointment of a substitute Escrow Agent by the Buyer and the Company; (ii) upon the petitioning of a court of competent jurisdiction seeking the appointment of a substitute Escrow Agent and the appointment by such court of a substitute Escrow Agent; or (iii) upon 60 days’ written notice to the Buyer and the Company and the appointment of a substitute Escrow Agent by the Buyer and the Company, and such resignation shall be effective from the date specified in such notice. After receipt of notice of the Escrow Agent’s intent to resign, the Buyer and the Company will work in good faith to select a substitute Escrow Agent. In case the office of the Escrow Agent shall become vacant for any reason, the Buyer and the Company shall appoint a bank or trust company with an office in New York City having a net worth (as reflected in its latest publicly available certified financial statements) in excess of $500,000,000 as successor Escrow Agent hereunder by an instrument or instruments in writing delivered by the Buyer and the Company to such successor Escrow Agent, whereupon such successor Escrow Agent shall succeed to all rights and obligations of the retiring Escrow Agents as if this Agreement were originally executed by such successor Escrow Agent, and the retiring Escrow Agent shall deliver to such successor Escrow Agent the Escrow Account and any interest accrued thereon.

(h) Subject to Sections 4, 8 and 14 hereof, the Escrow Agent shall not have any interest in the Escrow Account, but shall serve as escrow holder only and have possession thereof. Any payments of income from the Escrow Account shall be subject to withholding regulations then in force with respect to United States taxes. The parties hereto will provide the Escrow Agent with appropriate W-9 forms for tax identification number certification or non-resident alien certifications.

8. Indemnification. The Escrow Agent shall be indemnified by the Buyer and the Company against any claim or charge made against the Escrow Agent by reason of any action or failure to act in connection with any of the transactions contemplated by this Agreement, and against any loss the Escrow Agent may sustain in carrying out the terms of this Agreement, except as a result of the Escrow Agent’s bad faith, gross negligence or willful misconduct. The Buyer and the Company shall each be liable for one-half of any such claims, charges or losses.

9. Termination Date. This Agreement shall terminate on the date when all claims pursuant to Section 4 hereof are resolved and all funds have been disbursed from the Escrow Account in accordance with the provisions of this Agreement.

10. Interpleader. In the event that the Escrow Agent shall at any time be confronted with inconsistent claims or demands by the parties hereto, the Escrow Agent shall have the right to interplead said parties in any court of competent jurisdiction and request that such court determine such respective rights of the parties with respect to this Agreement, and upon doing so, the Escrow Agent automatically shall be released from any obligations or liability as a consequence of any such claims or demands, except that the Escrow Agent shall not be released from any liability for its bad faith, gross negligence or willful misconduct occurring during the time that it served as Escrow Agent.

11. Removal of the Escrow Agent. The Buyer and the Company, together, shall have the right to remove the Escrow Agent hereunder by giving notice in writing to the Escrow Agent, specifying the date upon which such removal shall take effect. In the event of such removal, the Buyer and the Company agree that, prior to the effective date of removal of the Escrow Agent, they will jointly appoint a successor to the Escrow Agent (the “Successor Escrow Agent”), and the Escrow Agent hereby agrees that, upon receiving joint written instructions from the Buyer and the Company, it shall turn over and deliver to such Successor Escrow Agent all of the funds in the Escrow Account and other amounts held by it pursuant to this Agreement in accordance with the terms of such written instructions and render the accounting required by Section 13 hereof.

12. Successor Escrow Agent. Upon receipt of the Escrow Fund and any other amounts held by the Escrow Agent pursuant to this Agreement, the Successor Escrow Agent shall thereupon be bound by all of the provisions hereof, and the term “Escrow Agent” as used herein shall mean the Successor Escrow Agent.

13. Accounting. In the event of the resignation or removal of the Escrow Agent, upon the termination of this Agreement or upon demand under reasonable circumstances, the Escrow Agent shall render to the Buyer and the Company and the Successor Escrow Agent(s), if any, an account in writing of the property constituting the Escrow Fund and all distributions therefrom unless waived in writing by both the Buyer and the Company. The Buyer and the Company together shall each pay one-half of all reasonable fees and expenses of the Escrow Agent for the preparation of such accounting, including the reasonable fees and disbursements of counsel.

14. Tax Matters. The parties agree that to the extent permitted by applicable law, the Buyer and the Company and their respective assigns will include the Interest in their respective

gross incomes for federal, state and local income tax (collectively, “Income Tax”) purposes in accordance with their respective percentage interest in the Escrow Fund, and pay any Income Tax resulting therefrom. The parties also agree for Income Tax purposes to treat all payments from the Buyer to the Escrow Fund as payments of purchase price to the Company. Notwithstanding the foregoing, the Escrow Agent shall report and, as required, withhold any taxes as it determines may be required by any law or regulation in effect. The Escrow Agent shall remit such taxes to the appropriate authorities.

15. Amendments. This Agreement may only be amended by the mutual written agreement of the Buyer, the Company and the Escrow Agent.

16. Notices. Any notices or other communications given hereunder shall be delivered personally or sent by telecopy or telefax, a reputable overnight courier service, or registered or certified mail, addressed as follows or to such other address of which the parties may have given notice:
