NEWS RELEASE TOWER SEMICONDUCTOR LTD. ANNOUNCES FIRST QUARTER 2003 RESULTS o FAB 1: STRONG FIRST 2003 QUARTER. o FAB 2: FIRST PRODUCTION ORDERS RECEIVED. MIGDAL HAEMEK, ISRAEL-- MAY 4, 2003-- Tower Semiconductor Ltd. (NASDAQ: TSEM; TASE: TSEM) today announced results for the first quarter ended March 31, 2003. Sales for the first quarter of 2003 were $12.6 million, an increase of 50% over sales of $8.4 million in the first quarter of 2002. This represents an increase of 9% over sales from operations in the prior quarter, when sales from operations were $11.6 million (the company recognized in the prior quarter an additional $4.0 million in revenue from a technology agreement). Total first quarter loss was $14.4 million, or $0.33 per share, including non-capitalized Fab 2 expenses (net) of $12.6 million, compared to a loss of $13.6 million, or $0.33 per share, including non-capitalized Fab 2 expenses (net) of $10.8 million, for the fourth quarter of 2002 and compared with a loss of $12.0 million, or $0.47 per share, including non-capitalized Fab 2 expenses (net) of $6.4 million, for the first quarter of 2002. Fab 1 operating results improved in the first quarter of 2003 due to both better unit sales and higher average selling price. Orders for Fab 1 increased relative to the prior quarter, and the Company anticipates Fab 1 sales in the second quarter of 2003 to continue to increase modestly over their Q1 2003 level. Tower expects to continue to generate positive operating cash flow from Fab 1 operations. Important advances were made in Tower's new flagship Fab 2 facility, for the production of devices at 0.18-micron and below. In addition to successful manufacturing of new prototypes for customers, the Company has received early orders for volume production from two of its wafer partners. Tower continues the installation of new equipment to ramp up production in Fab 2. "We are very pleased by the strides that we made in the first quarter of 2003. Both of our fabs performed well, strengthening our current position and laying the groundwork for future growth. In the second quarter Fab 2 is entering commercial 0.18 micron production with first volume customers orders," said Dr. Yoav Nissan-Cohen, co-CEO, Tower Semiconductor. Dr. Yoav Nissan-Cohen added: "We are proud that in the first quarter we were honored by Motorola with Gold Performance Excellence Award, for the fourth consecutive year. This award is another indication to Tower's position as a quality leader in the foundry industry." -MORE-

The Board of Directors Tower Semiconductor Ltd. Migdal Ha'emek -------------- Gentlemen: Re: REVIEW OF UNAUDITED CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS AS OF MARCH 31, 2003 ------------------------------------------------------ At your request, we have reviewed the condensed interim consolidated financial statements ("interim financial statements") of Tower Semiconductor Ltd. ("the Company") and its subsidiary, as follows: - Balance sheet as of March 31, 2003. - Statement of operations for the three months ended March 31, 2003. - Statement of changes in shareholders' equity for the three months ended March 31, 2003. - Statement of cash flows for the three months ended March 31, 2003. Our review was conducted in accordance with procedures prescribed by the Institute of Certified Public Accountants in Israel. The procedures included, inter alia, reading the aforementioned interim financial statements, reading the minutes of the shareholders' meetings and meetings of the board of directors and its committees, and making inquiries with the persons responsible for financial and accounting affairs. Since the review that was performed is limited in scope and does not constitute an audit in accordance with generally accepted auditing standards, we do not express an opinion on the aforementioned interim financial statements. In performing our review, nothing came to our attention which indicates that material adjustments are required to the interim financial statements for them to be deemed financial statements prepared in conformity with accounting principles generally accepted in Israel. Accounting principles generally accepted in Israel vary in certain significant respects from accounting principles generally accepted in the United States of America. The application of the latter would have affected the determination of the financial position and results of operations as of the dates and for the periods presented to the extent summarized in Note 5.

NOTE 3 - RECENT DEVELOPMENTS RELATING TO FAB 2 A. AMENDMENTS TO THE PRIMARY WAFER PARTNER AND EQUITY INVESTOR AGREEMENTS In February 2003, the Company's primary Wafer Partners and its Equity Investors entered into amendments to their agreements with the Company, pursuant to which the primary Wafer Partners and the Equity Investors agreed to advance their fifth milestone installment payment, in the aggregate amount of $41,069, regardless of its achievement. Of that amount, $24,641 shall be paid within five working days from obtaining all the approvals for the amendments as outlined below, and the remaining $16,428 shall be paid subject to obtaining all the approvals as outlined below and to raising by the Company of an aggregate of $22,000 (which under certain circumstances, may increase up to $26,000) (the "Additional Raising Amount") from specified financial sources, no later than December 31, 2003. Under certain circumstances, primarily the Banks' agreement to provide the Company with interim funding in the amount of $33,000 and that the Investment Center has not informed the Company that it is not continuing its funding of the Fab 2 project, and subject to the approval of the Company's shareholders, the primary Wafer Partners and Equity Investors agreed to advance an aggregate amount of $13,300 up to $15,800 of the $24,641 first installment. In consideration for their investments, for the first installment the primary Wafer Partners and the Equity Investors will be issued fully-paid Ordinary Shares of the Company, based on the average closing sale price of the Company's Ordinary Shares for the 30 trading days prior to the date the Company's Board of Directors approved the amendments ($2.983 per share), and for the second installment, based on the price at which the Company raises the Additional Raising Amount from specified financial sources. 7

TOWER SEMICONDUCTOR LTD. AND SUBSIDIARY NOTES TO UNAUDITED CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS AS OF MARCH 31, 2003 (dollars in thousands, except share data and per share data) NOTE 3 - RECENT DEVELOPMENTS RELATING TO FAB 2 (cont.) A. AMENDMENTS TO THE PRIMARY WAFER PARTNER AND EQUITY INVESTOR AGREEMENTS (cont.) Pursuant to the abovementioned amendments, the Company granted the primary Wafer Partners an option to convert an aggregate of up to $13,201 of the unutilized long-term customers' advances, which they may have as of December 31, 2005, into fully-paid Ordinary Shares of the Company, the amount of which shall be determined based on the average closing sale price of the Company's Ordinary Shares for the 30 trading days prior to such date. The option is exercisable during January 2006. In case such conversion occurs, and provided that the amount of shares issued is equivalent to or greater than 5% of the Company's outstanding share capital as of the conversion date, the Company undertook to offer to all of its other shareholders rights to purchase shares of the Company at the same price per share. Under the Fab 2 investment agreements, the fifth and last milestone towards the Wafer Partners and Equity Investors is to be achieved by mid-July 2003, when taking into account a seven and a half month grace period. Based on the current plan for Fab 2, the fifth milestone will not be achieved by its prescribed completion date. As stated above, subject to obtaining all the approvals for the amendments as outlined below, the Wafer Partners and Equity Investors agreed to waive the achievement of the fifth milestone. As part of the Wafer Partner and Equity Investor investment agreements, the Company undertook to raise a cumulative total of $50,000 from new wafer partners by March 31, 2003. In the framework of the amendments described above, and subject to obtaining all the approvals as outlined below, the primary Wafer Partners and Equity Investors have agreed to waive the requirement to raise that amount. The abovementioned amendments are subject to the approval of the Company's shareholders, Banks and other regulatory bodies (as of the approval date of the interim financial statements, the approval of these regulatory bodies has been obtained); to that the Investment Center shall not have informed the Company that it is not continuing its funding of the Fab 2 project; and to the receipt of the consent of the Banks to the amendments to the Facility Agreement, as outlined in B below. 8

B. AMENDMENTS TO THE FAB 2 FACILITY AGREEMENT According to the Facility Agreement with the Banks, as amended during 2002, the Company is obligated to raise $144,000 from specified financial sources, other than the already committed funds by the Wafer Partners and Equity Investors, as follows: by the end of 2002, an aggregate of $110,000 and by the end of 2003, an aggregate of $144,000. In the fourth quarter of 2002, the Company submitted a request to the Banks for amending the Facility Agreement by deferring the raising dates to be as follows: by the end of 2002, an aggregate of $84,000; by the end of March 2003, an aggregate of $110,000; and during 2004, an aggregate of $144,000. The Company further requested that should the primary Wafer Partners and Equity Investors make the first installment payment of $24,641 described in A above, this advanced amount will postpone the raising date of the aggregate $110,000 funding milestone. Due to the length of time in which the discussions with the Banks are held, the Company intends to update these raising dates and request to further defer them. During the negotiation period, the Banks have limited the full amount which the Company may drawdown pursuant to the Facility Agreement. Based on discussions held subsequent to the balance-sheet date with the Banks, management estimates that obtaining such deferrals is probable. According to the Facility Agreement, raising these amounts by the dates stated is a material provision. According to the Facility Agreement, the Company is obligated to comply with certain financial ratios, primarily total shareholders' equity to total assets, and substantial additional covenants in connection with the establishment of Fab 2 as stipulated in such agreement, primarily production and capacity milestones. As of March 31, 2003, the Company was in full compliance with the existing financial ratios and covenants, except for raising an amount of $24,000 from specified financial sources by December 31, 2002 as provided by the Facility Agreement with the Banks. The Company believes these financial ratios will be revised according to the updated plan for the construction of Fab 2, which is currently being reviewed by the Banks and a world leading first-tier consulting firm. For a request submitted by the Company in this regard, see the previous paragraph. Under the Fab 2 Facility Agreement, the remaining two milestones towards the Banks (the fifth and the sixth milestones) are to be achieved by mid-July 2003 and April 2004, respectively, when taking into account a seven and a half month grace period. Based on the current plan for Fab 2, these milestones will not be achieved by their prescribed completion dates, which are expected to be revised according to the updated plan. 9

AND SUBSIDIARY NOTES TO UNAUDITED CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS AS OF MARCH 31, 2003 (dollars in thousands, except share data and per share data) NOTE 3 - RECENT DEVELOPMENTS RELATING TO FAB 2 (cont.) C. APPROVED ENTERPRISE STATUS Under the terms of the Fab 2 approved enterprise program, investments in respect of Fab 2 are to be completed by December 31, 2005, a date in which a five-year period from obtaining the approval certificate terminates. Due to the later than planned commencement of construction of Fab 2 and prevailing market conditions, the Company does not currently expect to complete Fab 2 investments through 2005. The Company has notified the Investment Center of its revised investment schedule, and has also informed the Investment Center of the reduced rate of annual investments and lower than projected expectations for Fab 2 sales. As of the date of the interim financial statements, the Company's revised investments plan is currently being evaluated by the Investment Center. In addition, Israeli law currently limits the ability of the Investment Center to extend the investment period over five years. However, based on discussions held with the Investment Center, management estimates that obtaining arrangements with the Investment Center is probable. D. OTHER AGREEMENTS Through March 31, 2003 the Company had entered into several additional agreements related mainly to the construction, equipping and transfer of technology for Fab 2. The Company's aggregate commitment in connection with these agreements as of such date, including the Fab 2 construction agreement, amounted to $110,979. E. NON-CAPITALIZABLE EXPENSES AND OPERATING ACTIVITIES CASH FLOWS IN CONNECTION WITH FAB 2 In connection with establishing Fab 2, the Company incurred during the three-month period ended March 31, 2003 non-capitalizable expenses in the amount of $9,489, of which $5,027 was included in cost of sales and $4,462 was included in marketing, general and administrative (during the corresponding period - $3,351, $1,205 and $2,146, respectively). Net cash used in operating activities during the three-month period ended March 31, 2003 was $8,277. That amount includes net cash out flows in the amount of $12,195 attributable to the establishing of Fab 2 (during the corresponding period - $6,113 and $5,580, respectively). 10

AND SUBSIDIARY NOTES TO UNAUDITED CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS AS OF MARCH 31, 2003 (dollars in thousands, except share data and per share data) NOTE 4 - OTHER RECENT DEVELOPMENTS SHARE OPTION PLANS In the framework of the Company's Board of Directors resolution to increase the total number of options available for grant under all the Company's share option plans by an amount equal, in general, to 4% of the outstanding Ordinary Shares of the Company at the beginning of each year, 1,737,421 options were added to the Company's share option plans. Of that amount no options were granted to employees during the three-month period ended March 31, 2003. NOTE 5 - MATERIAL DIFFERENCES BETWEEN ISRAELI AND U.S. GAAP With regard to the Company's interim financial statements, the material differences between GAAP in Israel and in the U.S. relate to the following. See F below for the presentation of the Company's unaudited balance sheet as of March 31, 2003 in accordance with U.S. GAAP. A. PRESENTATION OF CASH AND SHORT-TERM AND LONG-TERM INTEREST-BEARING DEPOSITS DESIGNATED FOR INVESTMENTS RELATING TO FAB 2 In accordance with U.S. GAAP, cash, short-term and long-term interest-bearing deposits designated for investments relating to Fab 2 should be excluded from current assets and long-term investments and presented separately as a non-current asset. Accordingly, as of March 31, 2003 $21,924 and $12,056 were reclassified, respectively, from current assets and long-term investments to a long-term asset (as of December 31, 2002 - $51,338 and $11,893, respectively). B. PRESENTATION OF NET LONG-TERM LIABILITIES IN RESPECT OF EMPLOYEES Under U.S. GAAP, assets and liabilities relating to severance arrangements are to be presented separately and are not to be offset. Accordingly, an amount of $12,958 was reclassified from other long-term liabilities to long-term investments. C. HEDGING ACTIVITIES IN ACCORDANCE WITH U.S. GAAP (SFAS 133) Complying with SFAS 133 and SFAS 138 and the related interpretations thereon with respect to the Company's hedging transactions as of March 31, 2003 would have resulted in: an increase in the Company's current liabilities in the amount of $278; an increase in other long-term liabilities in the amount of $13,231; an increase in other comprehensive loss for the three months ended March 31, 2003 in the net amount of $1,747 and in the accumulated other comprehensive loss component of equity as of such date in the amount of $19,584; and in a decrease of $6,045 in property and equipment, net as of March 31, 2003. 11

D. IMPLEMENTATION OF SFAS 123 AND SFAS 148 Had compensation cost for the Company's share option plans been determined based on fair value at the grant dates of the awards in accordance with SFAS 123, as amended by SFAS 148, the Company's pro forma loss and loss per share would have been as follows: Three months ended March 31, ----------------------------------- 2003 2002 ---------------- ----------------- (unaudited) PRO FORMA LOSS Loss for the year, as reported $ (14,350) $ (12,014) Less - stock-based compensation determined under APB-25 19 52 Add - stock-based compensation determined under SFAS 123 (1,611) (2,212) ---------------- ----------------- Pro forma loss $ (15,942) $ (14,174) ================ ================= PRO FORMA BASIC LOSS PER SHARE As reported $ (0.33) $ (0.47) ================ ================= Pro forma $ (0.37) $ (0.56) ================ ================= E. SALE OF SECURITIES Under Accounting Principles Board Opinion No. 14 ("APB 14"), the proceeds from the sale of the securities in January 2002 are to be allocated to each of the securities issued based on their relative fair value, while according to Israeli GAAP such treatment is not required. Complying with APB 14, based on the average market value of each of the securities issued in the first three days following their issuance (in January 2002), would have resulted in an increase in shareholders' equity as of March 31, 2003 and December 31, 2002 in the amount of $2,363 (net of $196 related issuance expenses), and a decrease in convertible debentures as of such dates in the amount of $2,559. The effect of the U.S. GAAP application on the convertible debentures' discount amortization for the three-month period ended March 31, 2003 is immaterial. 12
