1.2 Further Assurances. At any time and from time to time after the Closing, at the Buyer’s request and without further consideration, the Seller promptly shall execute and deliver such instruments of sale, transfer, conveyance, assignment and confirmation, or, in the case of Licensed Intellectual Property, license and take such other action, as the Buyer may reasonably request to more effectively transfer, convey, assign or license to the Buyer, and to confirm the Buyer’s title to or interest in, all of the Purchased Assets and license rights with respect to the Licensed Intellectual Property. If at any time and from time to time after the Closing, the Seller identifies or is notified of specific Licensed Intellectual Property not previously disclosed to Buyer, the Seller will promptly disclose such Licensed Intellectual Property to the Buyer.

1.3 Purchase Price.

(a) General. The purchase price for all of the Purchased Assets (the “Purchase Price”) shall be as follows:

(i) three million two hundred twenty-six thousand three hundred sixty one dollars ($3,226,361.00) in cash paid at the Closing by wire transfer of immediately available funds to an account designated by the Seller (the “Closing Cash Amount”), subject to adjustment as provided in Sections 1.3(c) and (d);

(ii) up to Nine hundred seventy thousand dollars ($970,000.00) paid in accordance with Section 1.3(b) (the “Inventory Cap”); and

(iii) the assumption by the Buyer of the Assumed Liabilities (as defined in Section 1.4).

(b) Inventory Payments

(i) On the twentieth day of each February, May, August and November following the Closing (each a “Payment and Accounting Date”) and ending on the first Payment and Accounting Date following the five year anniversary of the Closing Date, the Buyer shall deliver to the Seller a detailed accounting in the form attached hereto as Exhibit 1.3(b) (the “Inventory Accounting”) of each item of Inventory consumed or otherwise used by the Buyer (the “Consumed Inventory”) during the immediately preceding calendar quarter and Seller’s cost thereof (“Seller’s Cost of Consumed Inventory”). The Inventory Accounting shall be certified by the Buyer’s chief financial officer as being true and accurate in all respects. For purposes of calculating Seller’s Cost of Consumed Inventory, the unit cost set forth on Schedule 1.1(a)(i) shall govern. Commencing with the Payment and Accounting Date on which the aggregate Seller’s Cost of Consumed Inventory shall have exceeded two million

two hundred seventy thousand five hundred forty one dollars ($2,270,541.00), the Buyer shall pay to the Seller by wire transfer of immediately available funds to an account designated by the Seller an amount equal to the Seller’s Cost of Consumed Inventory in excess of the sum of (x) two million two hundred seventy thousand five hundred forty one dollars ($2,270,541.00) and (y) any amounts previously paid to the Seller, if any, by operation of this Section 1.3(b). The aggregate payments pursuant to this Section 1.3(b)(i) shall not exceed the Inventory Cap. The Buyer shall consume an item available in Inventory prior to consuming that same item from another inventory source. To the extent the Buyer shall consume or use any specific item of inventory in lieu of a specific item of Inventory at a time when that specific item of Inventory is available for consumption and use, the Buyer shall be deemed to have consumed Inventory for purposes of calculating the amounts payable hereunder.

(ii) Should any specific items of Inventory be found to be unusable (“Unusable Inventory”) through no fault of the Buyer (e.g., design changes following Closing or Buyer breakage), the Buyer shall provide a list of such Unusable Inventory items and associated costs to the Seller on the next Payment and Accounting Date, and, at the written request of the Seller, deliver at the Seller’s cost such items of Unusable Inventory to the Seller together with a written explanation as to why such items are unusable. To the extent the Seller agrees that such items of Inventory are Unusable Inventory in the exercise of its reasonable judgment, the Seller’s cost thereof (based on the unit cost set forth on Schedule 1.1(a)(i)) shall not be included in the Seller’s Cost of Consumed Inventory and shall be applied to reduce the Inventory Cap.

(iii) The Buyer shall insure the Inventory against theft and casualty in amounts at least equal to Sellers cost. Upon the occurrence of any theft of or casualty to the Inventory, the Buyer shall pay to the Seller all insurance proceeds and any deductible related thereto in respect of such theft or casualty immediately upon receipt of such proceeds.

(iv) For purposes of verifying the Inventory Accounting and the amounts due and payable pursuant to this Section 1.3(c), the Seller and its representatives shall have the right to inspect the Inventory and the Buyer’s books and records related thereto, including sales records, upon reasonable prior notice.

(c) Adjustment of Closing Cash Amount for Inventory Adjustment. The Closing Cash Amount shall be reduced by an amount equal to (i) the Seller’s cost (calculated in accordance with the unit cost set forth on Schedule 1.1(a)(i)) of any Inventory consumed by the Seller after March 31, 2004, and prior to the Closing and (ii) the Seller’s cost of Inventory which has been the subject of a casualty loss during such period.

(d) Adjustment of Closing Cash Amount for Warranty Claims. The Closing Cash Amount shall be reduced by an amount equal to the greater of (x) 2% of total sales of (i) parts and retrofits sold during the 90-day period prior to the Closing Date and (ii) retrofits, equipment and services still under warranty as listed in Schedule 1.3(d), in each case exclusively of the Business; provided that any item described in the foregoing clauses (i) or (ii) shall not be counted twice in performing the calculation of the adjustment provided for herein and (y) the actual amount of warranty costs incurred exclusively in the Business during the six months ended March 31, 2004 as reflected in the audited financial statements for the year ended March 31, 2004. For purposes of calculating total sales, freight and taxes shall be excluded.

1.4 Assumption of Liabilities.

(a) At the Closing, the Buyer shall assume and agree to pay when due, perform and discharge in accordance with the terms thereof only those liabilities and obligations of the Seller for future performance after the Closing (i) under the Assigned Contracts included in the Purchased Assets and (ii) for product warranty claims relating to those products and services manufactured or provided exclusively by the Business without regard to when any such claim might arise and whether or not such claim arises under an Assigned Contract, as long as such product or service was listed on Schedule 1.3(d) or the related warranty was given by the Seller after the date hereof through the Closing Date in the ordinary course of business (the “Assumed Liabilities”). For the avoidance of doubt, assumed warranty claims shall include all product warranty claims in relation to APEX Process Management Software sold by Seller prior to the Closing or pursuant to the agreements set forth on Schedule 1.4(b)(ix). The Buyer’s assumption of the Assumed Liabilities shall in no way expand the rights or remedies of third parties against the Buyer as compared to the rights and remedies which such parties would have had against the Seller had this Agreement not been consummated.

(b) The Buyer shall not assume and shall not in any way be responsible for any of the debts, liabilities or obligations of the Seller, whether or not related to the Purchased Assets, unless expressly included among the Assumed Liabilities pursuant to Section 1.4(a) above. All such debts, liabilities and obligations of the Seller, other than the Assumed Liabilities, shall be referred to herein as the “Retained Liabilities” and shall include without limitation the following:

(i) any and all principal, interest, fees, expenses and other obligations of the Seller in respect of borrowed money, capital leases and installment purchases or any agreement with respect thereto (other than those to be performed after the Closing under the Assigned Contracts);

(ii) any and all liabilities or obligations of the Seller relating to Taxes (whether or not set forth on a Schedule hereto) including without limitation (A) Taxes incurred or payable by the Seller in connection with or arising out of the transactions contemplated hereby (subject to the provisions of Section 9.2(b)), (B) Taxes incurred or payable by the Seller as a result of actions or operations of the Seller prior to the Closing Date, and (C) Taxes owed or obligations incurred with respect to any tax audits of the Seller; provided, however, that notwithstanding any of the foregoing, the real estate taxes due in connection with that certain Commercial Lease dated February 23, 2000 between Wakefield Materials Corp., as landlord, and the Seller, as tenant, for 12,500 square feet of space at ▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇▇▇ (the “Real Property Lease” shall be apportioned as set forth in the Assignment and Assumption of Lease and Landlord’s Consent (the “Assignment of Lease”) to be delivered at the Closing in accordance with the provisions of Section 6.7(f) hereof. For purposes of this Agreement, “Taxes” shall mean all federal, state, local and foreign income, property, sales, value added, use, franchise, employment, withholding, excise, transfer and other taxes, tariffs and governmental charges of any nature whatsoever, together with any interest, penalties or additions with respect thereto;

(iii) liabilities or obligations of the Seller under this Agreement or any other agreement entered into by the Seller in connection with the transactions contemplated hereby;

(iv) other than in respect of warranty claims, liabilities or obligations relating to or arising out of any litigation relating to or arising out of the Business or the Purchased Assets prior to the Closing Date;

(v) liabilities or obligations with respect to any pensions, profit sharing, retirement, employee benefit, incentive compensation, commission arrangement, severance or similar plan, benefit or arrangement established or maintained at any time by the Seller or relating to the employees of the Business with respect to benefits accrued or claims incurred on or prior to the Closing Date;

(vi) liabilities or obligations relating to any Encumbrances on any of the Purchased Assets existing or arising with respect to matters occurring on or prior to the Closing Date;

(vii) liabilities or obligations relating to product liability claims arising out of products manufactured or sold by the Seller prior to the Closing Date and the operation of the Business prior to the Closing Date; provided that the Seller shall not be liable for any such claims if and to the extent they arise from actions taken by the Buyer in the servicing of any such products after the Closing Date;

(viii) any expenses to be borne under this Agreement by the Seller including without limitation expenses incurred by the Seller and related to or arising out of the transactions contemplated by this Agreement;

(ix) liabilities or obligations for product warranty claims of the Seller covered by the purchase orders identified on Schedule 1.4(b)(ix) (the “Commingled Contracts”) to the extent such product warranty claims do not specifically relate to products of the Business; and

(x) liabilities for services received and rents accrued prior to Closing.

(c) Third-Party Consents. To the extent that any of the Purchased Assets is not assignable without the consent, waiver or approval of another person, this Agreement shall not constitute an assignment or an attempted assignment of such Purchased Asset. If such assignment or attempted assignment would constitute a breach, violation or default with respect to such Purchased Asset, then the Seller shall, for the benefit of the Buyer, use its commercially reasonable efforts to obtain, or cause to be obtained, such consents, waivers and approvals as soon as practicable following the Closing Date; provided that the Seller shall not be obligated to pay any amounts in respect of obtaining such consent, waivers or approvals and the Buyer shall cooperate with and assist the Seller to this end. If any such consent, waiver or approval shall not be obtained despite the Seller’s commercially reasonable efforts to procure such consent, waiver or approval, then the Seller and the Buyer shall cooperate in any reasonable arrangement designed to provide the Buyer with the benefits intended to be assigned to the Buyer and the obligations assumed by the Buyer with respect to the underlying Purchased Asset, including,

without limitation, in the case of any Assigned Contracts, having the Seller subcontract to the Buyer for the completion of work under such Assigned Contracts on terms that are financially neutral relative to the what the financial position of the Buyer and the Seller would have been had the consent been obtained. Nothing contained in this Section 1.4(c) shall modify or otherwise affect the condition set forth in Section 6.4.

1.5 Allocation of Purchase Price and Assumed Liabilities. The aggregate amount of the Purchase Price, including the Assumed Liabilities, shall be allocated among the Purchased Assets as set forth on Schedule 1.5 hereto. The Buyer and the Seller shall report the sale and purchase of the Purchased Assets on all tax returns and tax forms (including, without limitation, Form 8594 of the Internal Revenue Service) in a manner consistent with such allocation and shall not, in connection with the filing of such returns or forms, make any allocation of the Purchase Price and the Assumed Liabilities which is inconsistent with that allocation.

From and after the date hereof and until the Closing Date, the Seller shall conduct the Business in the ordinary course of business and in a manner consistent with the practices of the Seller during the preceding twelve-month period, except as agreed to in writing between the Seller and the Buyer. Without the prior written consent of the Buyer, the Seller shall not, except in connection with the transactions contemplated by this Agreement:

(a) incur any obligation or liability (absolute or contingent) with respect to the Business, except current liabilities incurred and obligations under contracts entered into in the ordinary course of business, which individually do not exceed $10,000, unless it is for the purchase of inventory for which the Seller has a customer purchase order for an amount equal to at least 130% of its cost;

5.4 Continuing Obligation to Inform. From time to time prior to the Closing, the Seller and the Buyer will deliver or cause to be delivered to the other in writing in reasonable

detail supplemental information concerning events subsequent to the date hereof which would render any statement, representation or warranty in this Agreement or any information contained in any Schedule inaccurate or incomplete in any material respect at any time after the date hereof until the Closing Date. The delivery of such supplemental information pursuant to this Section 5.4 shall (a) not cure any breach of any representation or warranty requiring disclosure of such matter prior to the date of this Agreement or otherwise limit or affect the remedies available hereunder to the party receiving such supplemental information, and (b) have no effect in determining the satisfaction of the conditions set forth in Article 6 and Article 7 hereof; provided, however, that the delivery of such supplemental information shall have the effect of precluding an indemnity claim pursuant to Article 8 based on any such supplemental information which has been disclosed in all material respects in accordance with this Section 5.4.

5.5 Confidentiality.

(a) Each party hereto will (and will use its commercially reasonable efforts to cause its Affiliates and their representatives to) (i) hold in strict confidence from and not disclose to any person other than such Affiliates and representatives and (ii) not use for any purpose other than evaluating and negotiating the transactions contemplated by this Agreement (unless (x) compelled to disclose by judicial or administrative process (including without limitation in connection with obtaining the necessary approvals of this Agreement and the transactions contemplated hereby of governmental or regulatory authorities) by other requirements of law, provided that the recipient of such information and documents provides prior written notice to the other party of such disclosure and takes reasonable and lawful actions to avoid and/or minimize the extent of such disclosure or (y) disclosed in an action or proceeding brought by a party hereto in pursuit of its rights or any exercise of its remedies hereunder), all documents and information concerning the other party or any of its Affiliates furnished to it by the other party or such other party’s representatives in connection with this Agreement or the transactions contemplated hereby, except to the extent such documents or information can be shown to have been (A) previously known to the party receiving such documents or information through no wrongful act on the part of such receiving party, (B) in the public domain (either prior to or after the furnishing of such documents or information hereunder) through no fault of such receiving party or (C) later acquired by the receiving party from another source having the legal right to disclose such information or documents; provided that following the Closing the foregoing restrictions will not apply to the Buyer’s use of documents and information concerning the Business or the Purchased Assets furnished by the Seller hereunder. In the event the transactions contemplated hereby are not consummated, upon the request of the other party, each party hereto will, and will cause its Affiliates, any person who is provided, or who is considering providing, financing to such party and their respective representatives to, promptly (in no event later than (5) days after such request) redeliver or cause to be redelivered all copies of documents and information furnished by the other party in connection with this Agreement or the transactions contemplated hereby and destroy or cause to be destroyed all notes, memoranda, summaries, analyses, compilations and other writings related thereto or based thereon prepared by the party furnished such documents or information and its representatives.

(b) To the extent reasonably practicable, prior to any disclosure required by law, regulation or judicial order, the party required to make disclosure shall advise the other party of such requirement so that the non-disclosing party may seek a protective order.

5.6 Noncompetition and Nonsolicitation by Seller.

(a) For a period of twenty (20) years from and after the Closing, neither the Seller nor any of its Affiliates, will directly or indirectly, or as an owner, partner, employee, consultant or participant in any business entity, engage in or assist any other person to engage in any business which competes with the Business , as currently conducted, anywhere in the world. Additionally, for a period of three (3) years from and after the Closing, neither the Seller nor any of its Affiliates, will directly or indirectly, solicit for employment any Transferred Employee who is an employee of the Buyer, except to the extent that solicitation occurs as a result of advertisements or other general employment solicitations by or on behalf of the Seller. The covenants contained in this Section 5.6(a) in respect of Seller’s Affiliates shall not apply to Kokusai Electric Semiconductor Service Inc. in Japan or to Kokusai Electric Europe GmbH (“KEE”) in Europe which is bound by a similar covenant set forth in Section 5.6(a) of an Asset Purchase Agreement dated the date hereof (the “KEE Agreement”) by and between the Buyer and KEE (the “KEE Agreement”).

(b) The restrictions contained in the foregoing paragraph shall not be breached as a result of (i) any of the ownership or other rights to acquire by the Seller or any of its Affiliates of not more than an aggregate of 1% of any class of securities registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), of a person engaged in the Business or (ii) the Seller or any of its Affiliates acquiring a business (in whatever form) that engages in the Business, provided that less than 10% of the net sales of the acquired business in the previous 12 month period is derived from activities directly relating to the Business, or (iii) any rights granted in accordance with the Patent License Agreement, the APEX License Agreement, the Controller License Agreement and the Technology License Agreement.

(c) In the event that any court of competent jurisdiction shall determine that this Section 5.6, or any portion hereof, shall be void or unenforceable in any respect, then this Section 5.6 shall be deemed limited to the extent that such court determines it enforceable, and as so limited shall remain in full force and effect.

5.7 Injunctive Relief; Limitation on Scope.

The Seller acknowledges that any breach or threatened breach of the provisions of Section 5.6 of this Agreement will cause irreparable injury to the Buyer for which an adequate monetary remedy does not exist. Accordingly, in the event of any such breach or threatened breach, the Buyer shall be entitled, in addition to the exercise of other remedies, to seek and obtain injunctive relief, without necessity of posting a bond, restraining the Seller from committing such breach or threatened breach.

5.8 Nonsolicitation by Buyer; Injunctive Relief; Limitation on Scope.

(a) For the period of three (3) years from and after the Closing, the Buyer or any Affiliate of the Buyer will not, directly or indirectly, (i) solicit for employment any person who is an employee of the Seller (other than the employees of the Seller who are set forth on Schedule 4.3(a)), except to the extent that solicitation occurs as a result of advertisements or other general employment solicitations, and (ii) employ any person who is an employee of the Seller.

(b) The Buyer acknowledges that any breach or threatened breach of the provisions of subsection (a) of this Section 5.8 will cause irreparable injury to the Seller for which an adequate monetary remedy does not exist. Accordingly, in the event of any such breach or threatened breach, the Seller shall be entitled, in addition to the exercise of other remedies, to seek and obtain injunctive relief, without necessity of posting a bond, restraining the Buyer from committing such breach or threatened breach.

5.9 Covenant to Meet Closing Conditions. The Buyer and the Seller will, and will cause their affiliated and related parties to, cooperate and expend commercially reasonable efforts to meet and fulfill the conditions to Closing and other obligations to be performed or fulfilled by them under this Agreement to the end that the transactions contemplated by this Agreement shall be consummated.

5.10 Buyer Services. Following the Closing, Buyer shall provide [describe services] to those customers of Seller set forth on Schedule 5.10 in accordance with the terms set forth on Schedule 5.10.

5.11 Buyer Maintenance Services. From and after the Closing, the Buyer shall make available to the Seller’s customers to whom the Seller supplied systems for the Business prior to the Closing at least the same levels and quality of maintenance services as were provided by the Seller to such customers prior to the Closing.

5.12 Audited Financial Statements. Following the date hereof, Seller shall use commercially reasonable efforts to prepare financial statements (the “Financial Statements”) for the Business covering the fiscal years ended March 31, 2003 and 2004 (the “Annual Financial Statements”) and for any subsequent interim period in accordance with the requirements of Regulation S-X under the Exchange Act, except to the extent waived by the Securities and Exchange Commission (the “SEC”), and shall use its commercially reasonable efforts to cause Seller’s Auditor to audit the Annual Financial Statements in order to allow Buyer to comply with its reporting obligations in accordance with Item 7(a) of SEC Form 8-K in connection with the transaction contemplated hereby. The unaudited interim Financial Statement shall only cover any subsequent interim period mandated by Rule 3-05(b)(2) of Regulation S-X under the Securities Exchange Act of 1934, as amended. To the extent that it is not reasonably practical to exclude Seller’s retained Apogee business from the Financial Statements, the parties agree that the Financial Statements may include such business to the extent permitted under Regulation S-X or a waiver from the SEC. The audited Annual Financial Statements shall be delivered to Buyer three (3) business days prior to the Closing Date and the interim Financial Statements shall be delivered as soon thereafter as is reasonably practical under the circumstances, but not later than 45 days after the Closing Date. The out-of-pocket cost of preparing and auditing the Financial Statements shall be borne 50% by Buyer and 50% by Seller in the event the Closing shall have occurred; provided, however, that in the event of a termination of this Agreement in accordance with Section 10.3, the breaching party shall pay 100% of the out-of-pocket cost of preparing and auditing the Financial Statements. Buyer shall pay its share (based on the assumption that the Closing shall take place) of the out-of-pocket cost of preparing and auditing

the Financial Statements monthly within five (5) days of the rendering of an invoice by Seller. If this Agreement is terminated in accordance with Section 10.3, the party who is liable for the full out-of-pocket cost of preparing the Financial Statements shall pay the other party any amounts due within five (5) days of such termination. To the extent that the Seller is unable, despite the use of commercially reasonable efforts, to produce the Financial Statements or obtain the audit required by this Section 5.12, the Buyer shall use its commercially reasonable efforts to cause the SEC to accept the Financial Statements and audit that the Seller can produce and obtain in lieu of those required by Regulation S-X. The inability, despite the use of commercially reasonable efforts, of (i) the Seller to produce Financial Statements and obtain the audit required by this Section 5.12 and (ii) the Buyer to cause the SEC to accept the Financial Statements and audit the Seller is able to produce and obtain shall not be breaches of this agreement and the obligations of the parties hereunder and the parties each waive any and all rights or claims they may otherwise have hereunder in respect of the same.

5.13 Accounts Receivables. To the extent either party shall receive payment of any accounts receivable belonging to the other party, the party receiving such payment shall promptly upon receipt of such payment pay and deliver such payment to the other party.

The Indemnifying Party shall not settle or compromise any such claim or demand, unless the Indemnified Party is given a full, complete and unconditional release of any and all liability by all relevant parties relating thereto. If the Indemnifying Party does not assume the defense of any such claim or litigation resulting therefrom within 30 days after the date such claim is made, (a) the Indemnified Party may defend against such claim or litigation, in such manner as it may deem appropriate, including, without limitation, settling such claim or litigation, after giving notice of the same to the Indemnifying Party, on such terms as the Indemnified Party may deem appropriate, and (b) the Indemnifying Party shall be entitled to participate in (but not control) the defense of such action, with its counsel and at its own expense.
