ASSET PURCHASE AGREEMENT THIS ASSET PURCHASE AGREEMENT (the "Agreement") is entered into as of September 30, 1997, by and among ASYST TECHNOLOGIES, INC., a California corporation and ASYST AUTOMATION, INC., a Delaware corporation (collectively, the "Sellers") and PALO ALTO TECHNOLOGIES, INC., a California corporation (the "Buyer"). RECITALS WHEREAS, Sellers have been engaged in the business of developing and marketing automation products for use in semiconductor manufacturing and has announced its intention to withdraw from such business (the "Business"); WHEREAS, Sellers have in the course of operating the Business developed preliminary product designs and prototypes for products related to the automation of semiconductor manufacturing that have not been marketed and Sellers own certain equipment useful in this product development that it will not need to meet its remaining customer obligations associated with the Business; and WHEREAS, Buyer desires to purchase from Sellers and Sellers desire to sell to Buyer, such software, designs, prototypes and equipment, together with Sellers' intellectual property rights pertaining thereto all as described in Exhibit A hereto (collectively, the "Assets") on the terms and subject to the conditions hereinafter set forth. AGREEMENT NOW, THEREFORE, in consideration of the foregoing recitals and the mutual promises, representations, warranties, covenants and agreements hereinafter set forth, and intending to be legally bound, the parties hereto hereby agree as follows: SECTION 1. SALE OF ASSETS. Upon the terms and subject to the conditions set forth in this Agreement, on the Closing Date (as defined below), Sellers shall sell, convey, assign, grant, transfer and deliver to Buyer, and Buyer shall purchase, acquire and receive from Sellers the Assets, free and clear of all liens, mortgages, pledges, security interests, restrictions, prior assignments, encumbrances and claims of every kind, nature or character ("Liens"). The parties acknowledge that Sellers' rights under the Software License Agreement (the "License Agreement") among Asyst Automation, Inc., Toshiba Mechatronics Co., Ltd. ("Toshiba") and Mitsui & Co., Ltd. (relating to the MCS software) are intended to be included in the Assets but that the License Agreement may only be assigned by Sellers to Buyer with the consent of Toshiba. Sellers will use commercially reasonable efforts to obtain such consent. Notwithstanding any such assignment, Sellers shall remain responsible to pay Toshiba the installment payments set forth in Section 5.1 of the License Agreement and Buyer shall be liable 1. for royalties payable under Section 5.2 of the License Agreement for software sold by Buyer. Sellers shall have no further liability to Buyer pursuant to the License Agreement. Any intellectual property relating to the Field (as defined below) which is developed by Sellers' employees whose principal work related to the Field including Mihir Parikh and Anthony Bonora on or before December 31, 1997, shall be deemed to be included within the Assets and to be the property of Buyer. SECTION 2. CONSIDERATION FOR TRANSFER OF THE ASSETS 2.1 PURCHASE PRICE. Subject to the terms and conditions of these Agreement, in consideration of the transfer of the Assets, Buyer shall pay to Sellers the "Earn-Out Payments" (as defined below) up to an aggregate of $2,000,000. Notwithstanding anything else in this Agreement to the contrary, except as specifically set forth in Section 1, Buyer shall not assume, pay, perform, or discharge, and Sellers shall solely retain, pay, perform and discharge, all obligations and liabilities of Sellers relating to the Business, whether disclosed, undisclosed, direct, indirect, fixed or contingent, known or unknown, incurred in the ordinary course of business or otherwise. 2.2 Earn-Out Payments. Subject to the terms and conditions of this Agreement, in consideration of the transfer of the Assets, Buyer shall pay to Sellers Earn-Out Payments equal to 4.0% of the Gross Revenue of Buyer. The Gross Revenue of Buyer means the Buyer's actual revenue from all sources relating to transport systems and transfer (conveyor to tool loadport and/or stocker) systems in connection with manufacturing automation (the "Field") less freight, sales tax and insurance, and shall be determined using Generally Accepted Accounting Principles. The Earn-Out Payments shall be paid quarterly within forty-five (45) days following the end of each quarter (the "Payment Date"). On each Payment Date, Buyer shall deliver to Sellers a statement setting forth in reasonable detail the Gross Revenue of Buyer and the Earn-Out Payments. 2.3 AUDIT. For six (6) months following the payment of the final Earn-Out Payment, Sellers shall have reasonable access to the financial books and records of Buyer and Buyer's successor-in-interest of the Business for the purpose of auditing the Earn-Out Payments, subject to reasonable confidentiality restrictions. If the audit results in any additional payments to Sellers in excess of ten thousand dollars ($10,000) (the "Minimum Earn-Out Discrepancy"), then Buyer shall be liable for the fees and expenses of the auditor. If the audit results in no additional payments to Sellers or payments below the Minimum Earn-Out Discrepancy, then Sellers shall be liable for the auditor's fees and expenses. Buyer shall make any additional payments to the Sellers within twenty (20) days after the completion of the audit. The auditor shall be a national accounting firm satisfactory to the Sellers and Buyer. 2.4 CONVERSION. The right to receive Earn-Out Payments pursuant to Section 2.1 may be converted, at the option of Sellers, into shares of Buyer's securities sold at the closing of an equity financing for Buyer in which the aggregate gross proceeds raised by Buyer (including any 2. previous sales of Buyer's equity) is at least $3,000,000; provided, however that if such conversion would cause Sellers to own more than 9.5% of the outstanding, voting stock of Buyer, then only such amount of Earn-Out Payments that would convert into 9.5% of the outstanding voting stock of the Company may be converted and the remaining Earn-Out Payments shall remain available for conversion at the option of Sellers in any subsequent financing. The number of shares issuable to Sellers upon conversion of the Earn-Out Payments in connection with any financing shall be equal to the principal amount of Earn-Out Payments that is being converted divided by the price per share at which Buyer sells its equity securities in such financing. Sellers shall not have the right to convert Earn-Out Payments which have been paid by Buyer pursuant to Section 2.2, and the amount of any such payments shall be deducted from the balance available for conversion hereunder. 2.5 LICENSE BACK. The parties acknowledge that Sellers' products may contain intellectual property sold to Buyer pursuant to this Agreement, accordingly, Buyer grants to Sellers the worldwide, non-exclusive, royalty-free, fully-paid and perpetual right and license, with the right of sublicense, in and to the intellectual property included within the Assets to use, sell, distribute, reproduce, modify, make and have made, any of the Sellers' current products in the Field and any of Sellers' current and future products outside the Field. The limitations on such license in this Section 2.5 with respect to the Field shall expire on May 15, 2002. 2.6 DISTRIBUTION. Buyer hereby grants Sellers the non-exclusive, worldwide right and license to distribute and sell any of Buyer's products on terms and conditions mutually acceptable to Buyer and Sellers which are no less favorable than the most favorable terms granted to other distributors of Buyer, provided that Buyer may grant exclusive distribution rights to third parties in particular markets if such exclusive distribution rights are first offered to Sellers on the same terms and conditions as later offered to such third party and Sellers do not accept the offer; provided, however, that Sellers have or are reasonably expected to have the capability of performing such exclusive distribution function in such particular markets in a reasonably comparable manner to such third party. This Section 2.6 shall terminate on the earlier of (i) the fifth anniversary of this Agreement or (ii) if Sellers offer for sale their own products relating to the automation of semiconductor manufacturing which compete directly with Buyer's products.
