Authorized Purposes For Use Of Confidential Information Under Foregoing Confidential Disclosure Agreement: FOR USE BY TOPEX IN SUPPLYING SEMICONDUCTOR DICE, WAFERS, PIECE PARTS, AND PACKAGED DEVICES TO NATIONAL. LETTER OF INTENT THIS LETTER OF INTENT is dated _______________ of August, 1991, by and between NATIONAL SEMICONDUCTOR CORPORATION, a Delaware Corporation, having a principal place of business at 2900 Semiconductor Drive, Santa Clara, California 95052-8090 (hereinafter "NSC") and THINK-O ELECTRIC COMPANY, a Japanese corporation, having a principal place of business at 150 Kinoko, Ibara-City, Okayama, 715 Japan (hereinafter "TEC"). NSC and/or TEC may be referred to herein as a "party" or the "parties" as the case may require. WITNESSETH: WHEREAS, NSC and TEC have entered into preliminary discussions concerning the creation of a business relationship between the parties; and WHEREAS, NSC and TEC desire to record and memorialize the substance of those discussions in order to construct a framework from which a final binding agreement can be negotiated. NOW, THEREFORE, in furtherance of the premises the parties hereto set forth the following: 1. NSC shall purchase discrete semiconductor dice and/or wafers, and will consider the purchase of other semiconductor materials and piece parts, from TEC on a preferred supplier basis. 2. TEC shall supply such materials to NSC as a preferred customer with special pricing and guaranteed production capacity. 3. Should TEC discrete semiconductors be successfully qualified by NSC and should the parties agree on price, quality, delivery and other terms and conditions of sale, then NSC shall agree to commence purchasing a minimum of Five Thousand (5,000) wafers, or dice equivalent, per month from TEC. Since the parties acknowledge that NSC requirements for discrete semiconductors may increase during the two year period following the signing of a final agreement by the parties, TEC agrees that it shall, at NSC's request, make available to NSC up to Fifteen Thousand (15,000) discrete semiconductor wafers per month. Depending upon TEC performance and semiconductor market conditions, the parties agree that this schedule can be extended and that the quantity of wafers to be delivered thereunder can be increased up to Twenty Thousand (20,000) or more per month. 4. The parties agree to cooperate and take all reasonable steps necessary to resolve any problems that may arise with regard to performance, price, quality or delivery. 5. The initial prices to NSC for TEC wafers shall be follows: Bias Combined Total Finished Resistor Wafers/Month Diodes Zeners Trans. Trans. Trans. ------------ ------ ------ ------ ------ ------ 4,000-9,999 $65.00 $80.00 $85.00 $95.00 $92.00 10,000 & Up $60.00 $76.00 $85.00 $95.00 $87.00 Diode and zener prices do not include front bump or back metal. Transistor prices do not include back metal, but shall sample probing. All prices include production masks and incidental tooling expenses. NSC shall supply mask masters. The listed prices are also based on yields of Ninety-eight (98%) percent for diodes and Ninty-five (95%) percent for transistors. 6. Initial deliveries by TEC shall be four (4) weeks after receipt of order. Following deliveries will be based upon a four (4) month rolling forecast supplied by NSC and updated monthly. 7. The parties agree to review pricing annually. 8. This Letter of Intent shall not be a binding commitment upon either party, but shall instead serve as a basis for good faith negotiations between NSC and TEC leading to a final binding contract. The parties agree to strive to execute such a contract not later than September 30, 1991. 9. The final contract shall be administered on behalf of TEC by Torex Semiconductor LTD., TEC's international operations management company. 10. Neither party shall publicize or otherwise disclose the terms of this relationship, this Letter of Intent, or the final agreement, without the prior written approval of the other party. IN WITNESS WHEREOF, the parties have had this Letter of Intent executed by their respective authorized officers on the day and date first written above.

Keiser - --------------------------------------- --------------------------------------- - --------------------------------------- --------------------------------------- - --------------------------------------- --------------------------------------- [ illegible ] - - All wafers are tested at T85, 100 spots/wafer - - A minimum of 95% wafer yield to the BV, leakage, Vbe portion of the specification for the target bin yield except when it is determined by both parties that the HFE target will cause the BV distribution to fall below the specification. An engineering plan to improve the BV distribution for these high HFE devices will be developed and reviewed in three periods. Along with the electrical yields in general. Examples are as follows: PRODUCT HFE RANK ------- -------- 05S - C1, C2 12R - B2, C1, C2 16J - A2, B1, B2 38J - B1, B2, C1 66R - B2, C1 74l - B1, B2 79L - A2, B1, B2, C1 - - A minimum 80% lot average yield to the HFE bin with no wafer in the lot having less than 40% yield to the HFE bin. - - For HFE bin targets where the HFE range is less than 2:1 or there is a high HFE requirement, the lot average yield for these bins is a minimum 60% with no wafer in the lot yielding less than 40%. These bins will be identified on the test programs. - - NSC and Torex agree to review these yields after a device has run for three periods to see if a change to the yield accept limit is needed. The target goal for the HFE bins is 90%. DIODE YIELD ACCEPTANCE All wafers are tested at T85 as follows: - - 5 wafers/lot sampled; 100 spots/wafer * If the yield is greater/= 93%, the lot is shipped to Cebu * If the 1 or more wafers have less than 93%, 5 more wafers in the lot are tested 2nd group of 5 wafers sampled; 100 spots/wafer * If all of these wafers greater/= 93%, the lot is shipped to Cebu * If one of more wafers yield less than 93%, the remaining wafers in the lot are tested Any wafer with yield less than 86% is scrapped at Think-O. Wafers with yield between 86-93% can be shipped to Cebu as long as the total number of wafers in this yield range does not exceed 15% of the shipment. This is to be reviewed in 30 days from today with a target yield goal of 96% or greater. - ----------------------------------------- ------------------------------------- Test Condition Min Max Test Condition Min Max - ----------------------------------------- ------------------------------------- VBE 1b=10mA 1.8 v VBE 1b=10mA 0.9 v - ----------------------------------------- ------------------------------------- ICBO Vcb= nA ICBO Vcb= nA - ----------------------------------------- ------------------------------------- ICES Vce=65v 100 nA ICES Vce=50v 100 nA - ----------------------------------------- ------------------------------------- IEBO Veb=7.0v 100 nA IEBO Veb=6.3v 100 nA - ----------------------------------------- ------------------------------------- BVCEO 1c=10mA 100 v BVCEO 1c=10mA 55 v - ----------------------------------------- ------------------------------------- BVCES 1c=100uA 110 v BVCES 1c=100uA 110 v - ----------------------------------------- ------------------------------------- BVEBO 1e=1.0mA 19.5 v BVEBO 1e=10uA 8.2 v - ----------------------------------------- ------------------------------------- HFE 1c=100mA 4K 100K HFE 1c=1.0mA 150 900 Vce=5.0v Vce=5.0v - ----------------------------------------- ------------------------------------- - --------------------------------------- --------------------------------------- HFE HFE HFE Order Bin HFE HFE HFE Order Bin Rank min max Rank min max - --------------------------------------- --------------------------------------- A1 4K 10K -1 A1 - --------------------------------------- --------------------------------------- A2 10K 25K -2 A2 150 275 -2 - --------------------------------------- --------------------------------------- B1 25K 35K -4 B1 275 450 -3 - --------------------------------------- --------------------------------------- B2 35K 70K -3 B2 450 550 -4 - --------------------------------------- --------------------------------------- C1 70K 100K -3 C1 550 650 -4 - --------------------------------------- --------------------------------------- C2 C2 650 900 -5 - --------------------------------------- --------------------------------------- - --------------------------------------- --------------------------------------- Date Rev Comment Signoff Date Rev Comment Signoff - --------------------------------------- --------------------------------------- 11/25/91 A Issue E.
