REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS During fiscal 1996, management compensation issues were reviewed by the Compensation and Option Committee which consisted of Messrs. Bell and Holbrook, and Dr. Hill. The function of the Compensation 7 10 and Option Committee is to review and recommend management compensation to the Board. The Compensation and Option Committee met three times in 1996. The Company believes that its ability to achieve the objectives of obtaining regulatory approval for and commercializing its circulatory support and graft products, and becoming profitable, is dependent largely upon the ability to recruit and retain qualified executives with substantive experience in the development, regulatory approval, manufacture, marketing and sale of new medical devices. The Company is competing for experienced executives within the San Francisco Bay Area, where an estimated 85 to 100 biotechnology/biomedical/pharmaceutical companies are located. In 1994, the Board adopted a policy designed to control the base salaries of its executives while providing sufficient incentives to attract and retain qualified personnel. In accordance with this policy, the Company strives to set executive base salaries by considering relative contribution of the position to achievement of the Company's goals and objectives, "market value" as defined by salaries of executives within the Bay Area with comparable experience in similar positions, and job-related responsibilities with respect to size of budget, number of subordinates and scope of activities. In general, the Company strives to set base salaries of new executives at market, which is defined as the average base salary of incumbents in comparable positions, and uses its 1993 and 1996 Stock Option Plans to facilitate recruiting and to retain qualified executives by providing long-term incentives. Typically, new executives are granted stock options as part of their initial employment package. During 1993, the Internal Revenue Code of 1986 was amended to include a provision that denies a deduction to publicly held corporations for compensation paid to "covered employees" (defined as the chief executive officer and the next four most highly compensated officers as of the end of the taxable year) to the extent that compensation paid to any "covered employee" exceeds $1 million in any taxable year of the corporation beginning after 1993. Certain "performance-based" compensation qualified for an exemption from the limits on deductions. It is the Company's policy to attempt to qualify compensation paid to its top executives for deductibility in order to maximize the Company's income tax deductions, to the extent that so qualifying the compensation is not inconsistent with the Company's fundamental compensation policies. Based upon the Internal Revenue Service's proposed regulations and compensation paid to the Company's "covered employees" for the 1996 tax year, all compensation paid by the Company in 1996 to such covered employees was deductible to the Company. Stock Options. The Company has determined that stock options are an important incentive for attracting and retaining qualified personnel, including executive-level personnel. Corporate Performance Criteria. Management presents to the Board a set of corporate goals for a succeeding period, generally ranging from 12 to 18 months, as part of the annual plan and budget process. These goals establish benchmarks for assessing overall corporate performance. Given the dynamic nature of the new medical device development process, progress toward the achievement of corporate goals is reviewed with the Board periodically together with a description of any change in circumstances that management believes may warrant an update to or revisions of these goals. The principal corporate goals for 1996 were the U.S. marketing launch of the newly approved Thoratec VAD System and the closing of a significant round of public equity financing. Periodic Salary Adjustments. Generally, executive salaries are reviewed annually, and salary adjustments may be awarded on the basis of increased responsibilities of individual executives over a period of time or the outstanding performance of individual executives as exhibited by consistently high standards in the execution of established duties, as described by the Chief Executive Officer to the Board. Company performance as a whole is a major consideration in the Board's decision to award any salary increases and, to a lesser extent, the Board also considers general economic conditions and trends. In July 1996, the base annual salaries of three Company executives were increased by 28%, which increases brought the salaries more in line with current market. These increases were considered and approved solely by members of the Board of Directors who are not employees of the Company. 8 11 Chief Executive Officer. Generally, the nonemployee members of the Board meet with the Chief Executive Officer to discuss the performance of the other executive officers and of the Company as a whole. The nonemployee members of the Board then meet in the absence of the Chief Executive Officer to discuss the performance of the Chief Executive Officer. In accordance with the terms of Mr. Grossman's employment agreement, the Board reviewed Mr. Grossman's performance after his first six months of employment. Based on his strong leadership and achievements of strategic and financial objectives for the year, including the marketing launch of Thoratec's VAD System and the closing of a public equity financing, Mr. Grossman was given a $25,000 increase (17%) in July of 1996 and was awarded a bonus of $67,375 for the fiscal year. Summary. The Board believes that it has established a program for compensation of the Company's executives which is fair and which aligns the financial incentives for executives with the interests of the Company's shareholders. COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION During 1996, no executive officer of the Company served on the board of directors or compensation committee of another company that had an executive officer serve on the Company's Board of Directors or its Compensation and Option Committee. COMPLIANCE WITH SECTION 16(A) OF THE EXCHANGE ACT Section 16(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), requires the Company's directors and executive officers, and persons who own more than ten percent of a registered class of the Company's equity securities, to file reports of ownership on Form 3 and changes in ownership on Form 4 or 5 with the Securities and Exchange Commission and the National Association of Securities Dealers. Such officers, directors and ten percent shareholders are also required by Securities and Exchange Commission rules to furnish the Company with copies of all Section 16(a) forms that they file. Based solely on its review of copies of such reports received or written representations from certain reporting persons, the Company believes that, during the fiscal year ended December 28, 1996, there has been no failure by any of its officers, directors or ten percent shareholders to file on a timely basis any reports required by Section 16(a). CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS In September 1995 the Company sold an aggregate of 13,333 shares of Common Stock to Bradley Resources Company for an aggregate purchase price of $52,000. George W. Holbrook, Jr., a Director of the Company, is the Managing Partner of Bradley Resources Company. In September 1994, the Company sold to Bradley Resources Company a convertible Promissory Note and warrants for the purchase of 6,275 shares of Common Stock for an aggregate purchase price of $50,000. In March 1996, Bradley Resources Company converted its Convertible Promissory Notes into 10,225 shares of Common Stock and exercised its warrant to purchase 6,380 shares of Common Stock at an exercise price of $4.50 per share. The shares of Common Stock acquired in these transactions are entitled to certain registration rights. In November 1992 the Company entered into a comprehensive agreement with COBE pursuant to which COBE acquired approximately 26% of the Common Stock of the Company and obtained the right to place two directors on the Board of Directors. In addition, COBE obtained a license to use the Company's biomaterials technology in certain of COBE's medical products and agreed to act as the Company's distributor in certain European countries. For the fiscal years ended December 1995 and 1996, sales to COBE represented approximately 26% and 2%, respectively, of the Company's net revenue. In 1995, the Company modified its distributor agreement with COBE and appointed Arrow International as its distributor in most of the former COBE countries. In March 1996, the Company and COBE modified their agreement to eliminate COBE's right to two Board seats. 9 12 STOCK PRICE PERFORMANCE GRAPH The following line graph illustrates a five-year comparison of the cumulative total shareholder return on the Common Stock against the cumulative total return of The Nasdaq Stock Market-U.S. Index and the Hambrecht & Quist Health Care Index, assuming $100 invested in the Common Stock and the two indexes on December 31, 1991.

FISCAL YEAR ENDING DECEMBER. 10 13 PROPOSAL TWO APPROVAL OF THE 1997 STOCK OPTION PLAN At the Annual Meeting, the shareholders are being asked to approve Thoratec's 1997 Stock Option Plan (the "1997 Option Plan"). DESCRIPTION OF THE 1997 OPTION PLAN The purposes of the 1997 Option Plan are to: encourage selected employees, directors and consultants to improve operations and increase profits of the Company; encourage selected employees, directors and consultants to accept or continue employment or association with the Company or its affiliates; and increase the interest of selected employees, directors and consultants in the Company's welfare through participation in the growth in value of the Common Stock of the Company. The Company can grant either incentive stock options ("ISOs") or nonqualified stock options ("NQOs") under the 1997 Option Plan. Only full-time employees of the Company, currently approximately 90 people, are eligible to receive ISOs or NQOs. Consultants and directors are eligible to receive only NQOs. Options granted expire 10 years after the date of grant, or earlier, in the event of termination of the optionee's employment, consulting or director relationship with the Company. The per share exercise price of ISOs may not be less than 100% of the fair market value of the Common Stock on the date of grant. The per share exercise price of NQOs may not be less than 85% of the fair market value of the Common Stock on the date of grant. A total of 1,000,000 shares of the Company's Common Stock have been reserved for issuance under the 1997 Option Plan, none of which have as yet been issued. The consideration payable for, upon exercise of, or for tax payable in connection with, an option grant may be paid in cash, by promissory note of the participant, or by delivery of other property, including securities of the Company, if authorized by the administrator of the 1997 Option Plan. The Company will not receive any consideration upon the grant of any options. Options generally may be exercised immediately, or may vest over four or five years, depending upon the particular grant, and must generally be exercised within three months after a participant's employment by, or consulting or director relationship with, the Company terminates. If termination is due to the participant's death, retirement or disability, the options may be exercised for six months thereafter. Shares issued upon exercise of options may be subject to a right of repurchase by the Company which generally lapses at the rate of 20% per year. The Board may amend, alter or discontinue the 1997 Option Plan or any option at any time, except that the consent of a participant is required if the participant's rights under an outstanding option would be impaired. In addition, to the extent required for the 1997 Option Plan to satisfy the conditions of Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or, with respect to provisions solely as they relate to ISOs, to the extent required for the 1997 Option Plan to comply with Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), the shareholders of the Company must approve any amendment, alteration or discontinuance of the 1997 Option Plan that would (i) increase the total number of shares reserved under the 1997 Option Plan, (ii) change the minimum price terms for option exercise, (iii) change the class of employees, consultants and directors eligible to participate in the 1997 Option Plan, (iv) extend the maximum option exercise period or (v) materially increase the benefits accruing to participants under the 1997 Option Plan. FEDERAL INCOME TAX CONSEQUENCES See "Certain Federal Income Tax Consequences" below for a discussion of federal income tax consequences relating to participation in the 1997 Option Plan. PROPOSAL; BOARD RECOMMENDATION Shareholders are being asked to approve the 1997 Option Plan. The affirmative vote of the holders of a majority of the outstanding shares of the Company represented and voting at the Annual Meeting is required for approval of the 1997 Option Plan. The Board recommends a vote "FOR APPROVAL" of the proposal. 11 14 PROPOSAL THREE APPROVAL OF AMENDMENTS TO THE 1996 NONEMPLOYEE DIRECTORS STOCK OPTION PLAN At the Annual Meeting, the shareholders are being asked to approve amendments to Thoratec's 1996 Nonemployee Directors Stock Option Plan (the "Directors Option Plan"). DESCRIPTION OF THE AMENDMENTS TO DIRECTORS OPTION PLAN The Board has approved, subject to shareholder approval, amendments to the Directors Option Plan. The Directors Option Plan provides for the automatic granting of nonqualified stock options to directors of the Company who are not employees of the Company or any parent or subsidiary of the Company and who have not been an employee of the Company or any parent or subsidiary of the Company in the previous 12 months ("Eligible Outside Directors"). Currently, each person who is newly elected or appointed as an Eligible Outside Director on or after the meeting of shareholders in 1996 will be granted an option to purchase 3,333 shares of Common Stock on the effective date of such initial election or appointment (the "Initial Grant") and thereafter, each Eligible Outside Director (including the existing outside directors) generally will be granted an option to purchase 1,667 shares of Common Stock on the date of the first meeting of the Board of Directors following the annual shareholders meeting (the "Annual Grant"). The proposed amendments to the Directors Option Plan increase the number of shares to be granted under the Initial Grant and Annual Grant to 10,000 and 5,000 shares, respectively, and provides that in any event, the Annual Grant will be made no later than June 15 of any year. DESCRIPTION OF THE DIRECTORS OPTION PLAN A total of 150,000 shares of the Company's Common Stock have been reserved for issuance under the Directors Option Plan. Options to purchase 16,665 shares have been granted, none of which has as yet been exercised. The Company currently has five nonemployee directors who are eligible to participate in the Directors Option Plan, all of whom have been nominated for election at the Annual Meeting. The exercise price of the options in all cases will be equal to the fair market value of Common Stock on the grant date. Each option granted pursuant to the Directors Option Plan expires ten years and two days after the date of grant or earlier in the event of the termination of the director's service on the Board. Each option granted under the Directors Option Plan is exercisable in full six months after the date of grant. The Company has the right to repurchase at the exercise price with respect to shares purchased upon exercise of options which expires with respect to one-eighth of the number of shares covered by such option six months after the date such option is granted and one-sixteenth of the number of shares covered by such option at the end of each three-month period thereafter. In the event of acquisition of the Company by a merger, consolidation, sale of all or substantially all of the Company's assets or acquisition of the Company's shares, such right of repurchase shall lapse with respect to twice the number of shares still subject to the right of repurchase. The Board may waive the directors fees in any given year and have the exercise price of options granted under the Directors Option Plan reduced by the amount of the fees so waived. The consideration payable in connection with any option (including any related taxes) may be paid by promissory note of the nonemployee director or by delivery of shares of Common Stock of the Company if such method of payment is approved by the administrator of the Directors Option Plan. Options generally terminate three months after a nonemployee director ceases to be, for any reason, a director of the Company, but if a nonemployee director ceases to be a director due to death, disability or retirement, the option may be exercised for twelve months after the termination. The Board may amend, alter, or discontinue the Directors Option Plan or any option at anytime, except that the consent of a participant is required if the participant's existing rights under an outstanding option would be impaired. In addition, to the extent required under applicable tax and securities laws and regulations, the shareholders of the Company must approve any amendment, alteration, or discontinuance of the Directors Option Plan that would increase the total number of shares reserved under the Directors Option Plan and in addition, the provisions of the plan governing who is granted options, the number of shares covered by each 12 15 option, the exercise price, and the period of exercisability and the timing of option grants may not be amended more than once every six months, other than for changes to comport with the Code or the Employee Retirement Income Security Act of 1974. The following table shows, based on the current composition of the Board and assuming approval of the amendments, the number of options which will be granted in 1997 and each year thereafter to the listed groups under the Directors Option Plan until there are no longer shares reserved for issuance or until the Directors Option Plan is terminated. NUMBER OF OPTIONS GRANTED ANNUALLY(1) --------------------- 1997 THEREAFTER ------ ---------- All executive officers as a group....................................... 0 0 All directors who are not executive officers as a group................. 25,000 25,000 All employees (other than executive) as a group......................... 0 0 - --------------- (1) All options granted at fair market value as of the date of grant. The Company believes it important that directors have meaningful equity ownership in Thoratec. The reason for creating a nondiscretionary option plan for nonemployee directors is so that outside directors may have the opportunity for such equity ownership and the Company believes the automatic granting of options is an effective method of providing equity ownership. FEDERAL INCOME TAX CONSEQUENCES See "Certain Federal Income Tax Consequences" below for a discussion of federal income tax consequences relating to participation in the Directors Option Plan. PROPOSAL; BOARD RECOMMENDATION Shareholders are being asked to approve the amendments to the Directors Option Plan. The affirmative vote of the holders of a majority of the outstanding shares of the Company represented and voting at the Annual Meeting is required for approval of the amendments to the Directors Option Plan. The Board recommends a vote "FOR APPROVAL" of the proposal. CERTAIN FEDERAL INCOME TAX CONSEQUENCES THE FOLLOWING SUMMARY OF FEDERAL INCOME TAX CONSEQUENCES IS BASED UPON EXISTING STATUTES, REGULATIONS AND INTERPRETATIONS THEREOF. THE APPLICABLE RULES ARE COMPLEX, AND INCOME TAX CONSEQUENCES MAY VARY DEPENDING UPON THE PARTICULAR CIRCUMSTANCES OF EACH PLAN PARTICIPANT. THIS PROXY STATEMENT DESCRIBES FEDERAL INCOME TAX CONSEQUENCES OF GENERAL APPLICABILITY BUT DOES NOT PURPORT TO DESCRIBE PARTICULAR CONSEQUENCES TO EACH INDIVIDUAL PLAN PARTICIPANT OR FOREIGN, STATE OR LOCAL INCOME TAX CONSEQUENCES, WHICH MAY DIFFER FROM UNITED STATES FEDERAL INCOME TAX CONSEQUENCES. INCENTIVE STOCK OPTIONS Award; Exercise. ISOs are intended to constitute "incentive stock options" within the meaning of Section 422 of the Code. ISOs may be granted only to employees of the Company (including directors who are also employees). An optionee does not recognize taxable income upon either the grant or exercise of an ISO. However, the excess of the fair market value of the shares purchased upon exercise over the option exercise price (the "Option Spread") is includable in the optionee's "alternative minimum taxable income" ("AMTI") for purposes of the alternative minimum tax ("AMT"). The Option Spread is generally measured on the date of exercise and is includable in the AMTI in the year of exercise. Special rules regarding the time 13 16 of AMTI inclusion may apply for shares subject to a repurchase right or other "substantial risk of forfeiture" (including, in the case of each person subject to the reporting requirements of Section 16 of the Exchange Act, limitations on resale of shares imposed under Section 16 (b) of the Exchange Act). Sale of Option Shares. If an optionee holds the shares purchased under an ISO for at least two years from the date the ISO was granted and for at least one year from the date the ISO was exercised, any gain from a sale of the shares other than the Company is taxable as long-term capital gain. Under these circumstances, the Company would not be entitled to a tax deduction at the time the ISO is exercised or at the time the stock is sold. If an optionee were to dispose of stock acquired pursuant to an ISO before the end of the required holding periods (a "Disqualifying Disposition"), the amount by which the market value of the stock at the time the ISO is exercised exceeds the exercise price (or, if less, the amount of gain realized on the sale) is taxable as ordinary income, the Company is entitled to a corresponding tax deduction. Such income is subject to information reporting requirements and may become subject to income and employment tax withholding. Gain from a Disqualifying Disposition in excess of the amount required to be recognized as ordinary income is capital gain. Optionees are required to notify the Company immediately prior to making a Disqualifying Disposition. If the stock is sold to the Company rather than to a third party, the sale may not produce a capital gain or loss but may constitute a redemption taxable as a dividend unless the redemption is "not essentially equivalent to a dividend" within the meaning of the Code. The timing and amount of income from a Disqualifying Disposition and the beginning of the optionee's holding period for determining whether capital gain or loss is long- or short-term may be affected if option stock is acquired subject to a repurchase right or other "substantial risk of forfeiture" (including in the case of each person subject to the reporting requirements of Section 16 of the Exchange Act, limitations on resale of shares imposed under Section 16(b) of the Exchange Act). Exercise With Stock. If an optionee pays for ISO shares with shares of the Company acquired under an ISO or a qualified employee stock purchase plan ("statutory option stock"), the tender of shares is a Disqualifying Disposition of the statutory option stock if the above-described (or other applicable) holding periods respecting those shares have not been satisfied. If the holding periods with respect to the statutory option stock are satisfied, or the shares were not acquired under a statutory stock option of the Company, then any appreciation in value of the surrendered shares is not taxable upon surrender. Special basis and holding period rules apply where previously owned non-statutory option stock is used to exercise an ISO. NONQUALIFIED STOCK OPTIONS Award; Exercise. An optionee is not taxable upon the award of a NQO. Federal income tax consequences upon exercise will depend upon whether the shares thereby acquired are subject to a "substantial risk of forfeiture." If the shares are not subject to a substantial risk of forfeiture, or if they are so restricted and the optionee files an election under Section 83(b) of the Code (a "Section 83(b) Election") with respect to the shares, the optionee will have ordinary income at the time of exercise measured by the Option Spread on the exercise date. The optionee's tax basis in the shares will be the fair market value of the shares on the date of exercise, and the holding period for purposes of determining whether capital gain or loss upon sale is long- or short-term also will begin on or immediately after that date. If the shares are subject to a substantial risk of forfeiture and no Section 83(b) Election is filed, the optionee will not be taxable upon exercise, but instead will have ordinary income on the date the restrictions lapse, in an amount equal to the difference between the amount paid for the shares under the NQO and their fair market value as of the date of lapse; in addition, the optionee's holding period will begin on the date of the lapse. Whether or not the shares are subject to a substantial risk of forfeiture, the amount of ordinary income taxable to an optionee who is an employee at the time of grant constitutes "supplemental wages" subject to withholding of income and employment taxes by the Company, and the Company receives a corresponding income tax deduction. Sale of Option Shares. Upon sale, other than to the Company, of shares acquired under a NQO, an optionee generally will recognize capital gain or loss to the extent of the difference between the sale price and the optionee's tax basis in the shares, which will be long-term gain or loss if the employee's holding period in 14 17 the shares is more than one year. If stock is sold to the Company, rather than to a third party, the sale may not produce capital gain or loss. A sale of shares to the Company will constitute a redemption of such shares, which could be taxable as a dividend unless the redemption is "not essentially equivalent to a dividend" within the meaning of the Code. Exercise with Stock. If an optionee tenders Common Stock to pay all or part of the exercise price of a NQO, the optionee will not have a taxable gain or deductible loss on the surrendered shares. Instead, shares acquired upon exercise that are equal in value to the fair market value of the shares surrendered in payment are treated as if they had been substituted for the surrendered shares, taking as their basis and holding period the basis and holding period that the optionee had in the surrendered shares. The additional shares are treated as newly acquired with a zero basis. If the surrendered shares are statutory option stock as described above under "Incentive Stock Options", with respect to which the applicable holding period requirements for favorable income tax treatment have not expired, then the newly acquired shares substituted for the statutory option shares should remain subject to the federal income tax rules governing the surrendered shares, but the surrender should not constitute a Disqualifying Disposition of the surrendered stock. SPECIAL FEDERAL INCOME TAX CONSIDERATION DUE TO SHORT SWING PROFIT RULE The potential liability of a person subject to Section 16 of the Exchange Act to repay short-swing profits from the resale of shares acquired under a Company plan constitutes a "substantial risk of forfeiture" within the meaning of the above described rules, which is generally treated as lapsing at such time as the potential liability under Section 16 lapses. Persons subject to Section 16 who would be required by Section 16 to repay profits from the immediate resale of stock acquired under a Company plan should consider whether to file a Section 83 (b) Election at the time they acquire stock under a Company plan in order to avoid deferral of the date that they are deemed to acquire shares for federal income tax purposes. INDEPENDENT AUDITORS The Board has selected Deloitte & Touche LLP as independent auditors to audit the financial statements of the Company for the 1997 fiscal year. Deloitte & Touche LLP has been engaged as the Company's auditors since the Company's inception in 1976. Representatives of Deloitte & Touche LLP are expected to be present at the Annual Meeting and will have an opportunity to make a statement if they desire to do so. The representatives of Deloitte & Touche LLP also will be available to respond to questions raised during the meeting. SHAREHOLDER PROPOSAL Proposals of shareholders of the Company which are intended to be presented at the Company's 1998 meeting of shareholders must be received by the Secretary of the Company no later than January 16, 1998, in order to be included in the proxy soliciting material relating to that meeting. OTHER MATTERS The Company knows of no other matters to be submitted at the Annual Meeting. If any other matters properly come before the Annual Meeting, it is the intention of the persons named in the enclosed proxy to vote the shares they represent as the Board may recommend.

GRANT OF OPTIONS (a) Subject to the terms and conditions of this Plan, if any person who is not an officer or employee of the Company is first elected or appointed as a member of the Board on or after the Company's annual meeting of shareholders held in 1996 but before the annual meeting of shareholders held in 1997, then on the effective date of such appointment or election of such person, the Company shall grant to such Nonemployee Director an Option to purchase 3,333 Shares at an exercise price equal to the Fair Market Value of such Shares on the date of such Option grant. If any person who is not an officer or employee of the Company is first elected or appointed as a member of the Board on or after the Company's annual meeting of shareholders held in 1997, then on the effective date of such appointment or election of such person, the Company shall grant to such Nonemployee Director an Option to purchase 10,000 Shares at an exercise price equal to the Fair Market Value of such Shares on the date of such Option grant. (b) Subject to the terms and conditions of this Plan, on the date of the first meeting of the Board immediately following each annual meeting of shareholders of the Company (even if held on the same day as the meeting of shareholders) which is held after the date this Plan is approved by the shareholders of the Company and before the annual meeting of shareholders held in 1997, the Company shall grant to each Nonemployee Director then in office an Option to purchase 1,667 Shares at an exercise price equal to the Fair Market Value of such Shares on the date of such Option grant. Subject to the terms and conditions of this Plan, on the date of the first meeting of the Board immediately following each annual meeting of shareholders of the Company (even if held on the same day as the meeting of shareholders) which is held on or after the annual meeting of shareholders held in 1997, the Company shall grant to each Nonemployee Director then in office an Option to purchase 5,000 Shares at an exercise price equal to the Fair Market Value of such Shares on the date of such Option grant. Provided, however, that if in any year an annual meeting of shareholders is not held by June 15, then on June 15 of any such year the Company shall grant to each Nonemployee Director then in office an Option to purchase 5,000 Shares at an exercise price equal to the Fair Market Value of such Shares on June 15 and the Company shall not thereafter grant any Options pursuant to this subsection (b) in any such year. Notwithstanding anything in this subsection (b) to the contrary, a director shall not receive an Option pursuant to this subsection (b) if such director has been first elected or appointed as a member of the Board within six months before the date on which an Option would be granted hereunder. (c) No Options shall be granted under this Plan after ten (10) years from the date of adoption of this Plan by the -4- 22 Board. Each Option shall be evidenced by a written Option Agreement, in form satisfactory to the Company, executed by the Company and the Nonemployee Director to whom such Option is granted; provided, however, that the failure by the Company, the Nonemployee Director or both to execute such an agreement shall not invalidate the granting of an Option. 7. DIRECTOR FEE ELECTION Upon election by the Board, all or any part of the Director Fees can be waived in any given year, and the Director Fees waived may be applied by the Board to reduce the exercise price of Options granted to the Nonemployee Directors pursuant to Sections 6(a) and 6(b). The amount of Director Fees waived may vary from year to year. By way of example, if the Board elects pursuant to this Section to waive an aggregate of $6,000 of Director Fees which would otherwise be payable to three Nonemployee Directors ($2,000 of fees for each), an amount of $6,000 ($2,000 each) shall be applied by the Board to reduce the exercise price of Options granted pursuant to Section 6(b), so that if each of the three Nonemployee Directors in this example are granted Options for 1,000 shares exercisable at $5.00 each, the $2,000 could be applied to reduce the exercise price of these options to $3.00 per share ($2,000 / 1,000 shares = $2.00 per share reduction in exercise price). 8. TERMS AND CONDITIONS OF OPTIONS Each Option granted under this Plan shall be subject to the terms and conditions set forth in this Section 8. 8.1 Changes in Capital Structure. Subject to Section 8.2, if the Common Stock is changed by reason of a stock split, reverse stock split, stock dividend or re-capitalization, or converted into or exchanged for other securities as a result of a merger, consolidation or reorganization, appropriate adjustments shall be made in: (a) the number and class of shares of Common Stock subject to this Plan and each Option outstanding under this Plan; and (b) the exercise price of each outstanding Option; provided, however, that the Company shall not be required to issue fractional shares as a result of any such adjustments. Each such adjustment shall be subject to approval by the Administrator in its sole discretion. 8.2 Time of Option Exercise. Subject to the other provisions of this Plan, each Option granted pursuant to this Plan shall be for a term of ten (10) years and two (2) days. Each Option granted under Section 6 of this Plan shall be exercisable in full six months after the date of grant. The Company shall have a right of repurchase at the option exercise price with respect to shares purchased upon exercise of Options granted pursuant to Section 6 which shall expire with respect to -5- 23 12 1/2% of the number of Shares covered by such Option six months after the date such Option is granted and shall expire with respect to 6 1/4% of the number of shares covered by such Option at the end of each three-month period thereafter. 8.3 Corporate Transactions. In connection with an acquisition of the Company affected by a merger, consolidation, sale of all or substantially all of the Company's assets, acquisition of shares, or any like occurrence in which the Company is involved, the right of repurchase specified in Section 8.2 shall lapse with respect to twice the number of shares then subject to such right of repurchase. The Administrator shall have the authority, in its sole discretion, to determine the time prior to consummation of such transaction when such right of repurchase shall so lapse. 8.4 Limitation on Other Grants. The Administrator shall have no discretion to grant Options under this Plan other than as set forth in Sections 6(a) and 6(b). 8.5 Nonassignability of Option Rights. No Option granted under this Plan shall be assignable or otherwise transferable by the Optionee, except by will or the laws of descent and distribution, or pursuant to a qualified domestic relations order as defined by the Code. During the life of an Optionee, an Option shall be exercisable only by the Optionee. 8.6 Payment. Except as provided below, payment in full, in cash, shall be made for all Option Shares purchased at the time written notice of exercise of an Option is given to the Company, and proceeds of any payment shall constitute general funds of the Company. Payment may also be made pursuant to a cashless exercise/sale procedure. At the time an Option is granted or exercised, the Administrator, in the exercise of its absolute discretion, may authorize any one or more of the following additional methods of payment: (a) acceptance of the Optionee's full recourse promissory note for all or part of the Option price, less any par value per share, which must be paid in cash, payable on such terms and bearing such interest rate as determined by the Administrator (but in no event less than the minimum interest rate specified under the Code at which no additional interest on debt instruments of such type would be imputed), which promissory note may be either secured or unsecured in such manner as the Administrator shall approve (including, without limitation, by a security interest in the Shares); (b) delivery by the Optionee of Common Stock already owned by the Optionee for all or part of the Option price, provided the Fair Market Value of such Common Stock is equal on the date of exercise to the Option price, or such portion thereof as the Optionee is authorized to pay by delivery of such stock; provided, however, that if an Optionee has exercised any portion of any option granted by the Company by delivery of Common Stock, -6- 24 the Optionee may not, within six (6) months following such exercise, exercise any Option granted under this Plan by delivery of Common Stock; and (c) any other consideration and method of payment to the extent permitted under the California Corporations Code. 8.7 Termination as Director. Unless determined otherwise by the Administrator in its absolute discretion, to the extent not already expired or exercised, an Option shall terminate at the earlier of: (a) the expiration of the term of the Option; or (b) three (3) months after the last day served by the Optionee as a director of the Company; provided, that an Option shall be exercisable after the date of termination of service as a director only to the extent exercisable on the date of termination; and provided further, that if termination of service as a director is due to the Optionee's death or "disability" (as determined in accordance with Section 22(e)(3) of the Code), the Optionee, or the Optionee's personal representative (or any other person who acquires the Option from the Optionee by will or the applicable laws of descent and distribution), may at any time within twelve (12) months after the termination of service as a director (or such lesser period as is specified in the Option Agreement but in no event after the expiration of the term of the Option), exercise the rights to the extent they were exercisable on the date of the termination. 8.8 Withholding and Employment Taxes. At the time of exercise of an Option (or at such later time(s) as the Company may prescribe), the Optionee shall remit to the Company in cash all applicable federal and state withholding and employment taxes. If authorized by the Administrator in its sole discretion, an Optionee shall be permitted to elect, by means of a form of election to be prescribed by the Administrator, to have shares of Common Stock which are acquired upon exercise of the Option withheld by the Company or to tender to the Company other shares of Common Stock or other securities of the Company owned by the Optionee on the date of determination of the amount of tax to be withheld as a result of the exercise of such Option (the "Tax Date") to pay the amount of tax that is required by law to be withheld by the Company as a result of the exercise of such Option. Any securities so withheld or tendered shall be valued by the Company as of the Tax Date. 8.9 Option Term. Each Option granted hereunder shall expire ten (10) years and two (2) days after the date of grant. 9. MANNER OF EXERCISE (a) An Optionee wishing to exercise an Option shall give written notice to the Company at its principal executive office, to the attention of the officer of the Company designated by the Administrator, accompanied by payment of the exercise -7- 25 price as provided in Section 8.6 and, if required, by payment of any federal or state withholding or employment taxes required to be withheld by virtue of exercise of the Option. The date the Company receives written notice of an exercise hereunder accompanied by payment of the exercise price and any required federal or state withholding or employment taxes will be considered as the date such Option was exercised. Unless otherwise provided by the Administrator, options may be exercised only twice in any calendar year. (b) Promptly after the date an Option is exercised, the Company shall, without stock issue or transfer taxes to the optionee or other person entitled to exercise the Option, deliver to the Optionee or such other person a certificate or certificates for the requisite number of shares of Common Stock. An Optionee or transferee of an Optionee shall not have any privileges as a stockholder with respect to any Common Stock covered by the Option until the date of issuance of a stock certificate. 10. NO RIGHT TO DIRECTORSHIP Neither this Plan nor any Option granted hereunder shall confer upon any Optionee any right with respect to continuation of the Optionee's membership on the Board or shall interfere in any way with provisions in the Company's Articles of Incorporation and By-Laws relating to the election, appointment, terms of office, and removal of members of the Board. 11. FINANCIAL INFORMATION The Company shall provide to each Optionee during the period such optionee holds an outstanding Option a copy of the financial statements of the Company as prepared either by the Company or independent certified public accountants of the Company. Such financial statements shall be delivered as soon as practicable following the end of the Company's fiscal year during the period Options are outstanding. 12. LEGAL REQUIREMENTS The Company shall not be obligated to offer or sell any Shares upon exercise of any Option unless the Shares are at that time effectively registered or exempt from registration under the federal securities laws and the offer and sale of the Shares are otherwise in compliance with all applicable securities laws and the regulations of any stock exchange on which the Company's securities may then be listed. The Company shall have no obligation to register the Shares covered by this Plan under the federal securities laws or take any other steps as may be necessary to enable the Shares covered by this Plan to be offered and sold under federal or other securities laws. Upon exercising -8- 26 all or any portion of an Option, an Optionee may be required to furnish representations or undertakings deemed appropriate by the Company to enable the offer and sale of the Shares or subsequent transfers of any interest in the Shares to comply with applicable securities laws. Certificates evidencing Shares acquired upon exercise of Options shall bear any legend required by, or useful for purposes of compliance with, applicable securities laws, this Plan or the Option Agreements. 13. AMENDMENTS TO PLAN The Board may amend this Plan at any time. Without the consent of an optionee, no amendment may adversely affect outstanding Options. No amendment shall require shareholder approval unless: (a) shareholder approval is required to meet the exemptions provided by Rule 16b-3, or any successor rule thereto; or (b) the Board otherwise concludes that shareholder approval is advisable. 14. SHAREHOLDER APPROVAL; TERM This Plan shall become effective upon adoption by the Board of Directors; provided, however, that no Option shall be exercisable unless and until written consent of holders of a majority of the outstanding shares of capital stock of the Company, or approval by holders of a majority of shares of capital stock of the Company present, or represented, and entitled to vote at a validly called shareholders' meeting (or such greater number as may be required by law or applicable governmental regulations or orders) is obtained within twelve (12) months after adoption by the Board. This Plan shall terminate ten (10) years after adoption by the Board unless terminated earlier by the Board. The Board may terminate this Plan at any time without shareholder approval. No Options shall be granted after termination of this Plan, but termination shall not affect rights and obligations under then outstanding Options. -9- 27 ANNEX II 1997 STOCK OPTION PLAN OF THORATEC LABORATORIES CORPORATION 28 TABLE OF CONTENTS PAGE ---- 1.

EFFECTIVE DATE OF PLAN.................................................................................. 9 -ii- 30 1997 STOCK OPTION PLAN OF THORATEC LABORATORIES CORPORATION 1. PURPOSES OF THE PLAN The purposes of the 1997 Stock Option Plan (the "Plan") of Thoratec Laboratories Corporation, a California corporation (the "Company"), are to: (a) Encourage selected directors, employees and consultants to improve operations and increase profits of the Company; (b) Encourage selected directors, employees and consultants to accept or continue employment or association with the Company or its Affiliates; and (c) Increase the interest of selected directors, employees and consultants in the Company's welfare through participation in the growth in value of the common stock of the Company (the "Common Stock"). Options granted under this Plan ("Options") may be "incentive stock options" ("ISOs") intended to satisfy the requirements of Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), or "nonqualified options" ("NQOs"). 2. ELIGIBLE PERSONS Every person who at the date of grant of an Option is a full-time employee of the Company or of any Affiliate (as defined below) of the Company is eligible to receive NQOs or ISOs under this Plan. Every person who at the date of grant is a consultant or non-employee director to the Company or any Affiliate (as defined below) of the Company is eligible to receive NQOs under this Plan. The term "Affiliate" as used in the Plan means a parent or subsidiary corporation as defined in the applicable provisions (currently Sections 424(e) and (f), respectively) of the Code. The term "employee" includes an officer or director who is an employee, of the Company. The term "consultant" includes persons employed by, or otherwise affiliated with, a consultant. 3. STOCK SUBJECT TO THIS PLAN Subject to the provisions of Section 6.1.1 of the Plan, the total number of shares of stock which may be issued under options granted pursuant to this Plan shall not exceed 1,000,000 shares of Common Stock. The shares covered by the portion of any grant under the Plan which expires unexercised shall become available again for grants under the Plan. 31 4. ADMINISTRATION (a) This Plan shall be administered by the Board of Directors of the Company (the "Board") or, either in its entirety or only insofar as required pursuant to Section 4(b) hereof, by a committee (the "Committee") of at least two Board members to which administration of the Plan, or of any portion of the Plan, is delegated (in either case, the "Administrator"). (b) From and after such time as the Company registers a class of equity securities under Section 12 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), it is intended that this Plan shall be administered in accordance with the requirements of Rule 16b-3 promulgated by the Securities and Exchange Commission ("Rule 16b-3"), or any successor rule thereto. (c) Subject to the other provisions of this Plan, the Administrator shall have the authority, in its discretion: (i) to grant Options; (ii) to determine the fair market value of the Common Stock subject to Options; (iii) to determine the exercise price of Options granted; (iv) to determine the persons to whom, and the time or times at which, Options shall be granted, and the number of shares subject to each Option; (v) to interpret this Plan; (vi) to prescribe, amend, and rescind rules and regulations relating to this Plan; (vii) to determine the terms and provisions of each Option granted (which need not be identical), including but not limited to, the time or times at which Options shall be exercisable; (viii) with the consent of the optionee, to modify or amend any Option; (ix) to defer (with the consent of the optionee) the exercise date of any Option; (x) to authorize any person to execute on behalf of the Company any instrument evidencing the grant of an Option; and (xi) to make all other determinations deemed necessary or advisable for the administration of this Plan. The Administrator may delegate nondiscretionary administrative duties to such employees of the Company as it deems proper. (d) All questions of interpretation, implementation, and application of this Plan shall be determined by the Administrator. Such determinations shall be final and binding on all persons. (e) With respect to persons subject to Section 16 of the Exchange Act, if any, transactions under this Plan are intended to comply with the applicable conditions of Rule 16b-3, or any successor rule thereto. To the extent any provision of this Plan or action by the Administrator fails to so comply, it shall be deemed null and void, to the extent permitted by law and deemed advisable by the Administrator. Notwithstanding the above, it shall be the responsibility of such persons, not of the Company or the Administrator, to comply with the requirements of Section 16 of the Exchange Act; and neither the Company nor the Administrator shall be liable if this Plan or any transaction under this Plan fails to comply with the applicable conditions of Rule 16b-3 or any successor rule thereto, or if any such person incurs any liability under Section 16 of the Exchange Act. -2- 32 5. GRANTING OF OPTIONS; OPTION AGREEMENT (a) No Options shall be granted under this Plan after ten years from the date of adoption of this Plan by the Board. (b) Each Option shall be evidenced by a written stock option agreement, in form satisfactory to the Company, executed by the Company and the person to whom such Option is granted; provided, however, that the failure by the Company, the optionee, or both to execute such an agreement shall not invalidate the granting of an Option, although the exercise of each option shall be subject to Section 6.1.3. (c) The stock option agreement shall specify whether each Option it evidences is a NQO or an ISO. (d) Subject to Section 6.3.3 with respect to ISOs, the Administrator may approve the grant of Options under this Plan to persons who are expected to become directors, employees or consultants of the Company, but are not directors, employees or consultants at the date of approval. 6. TERMS AND CONDITIONS OF OPTIONS Each Option granted under this Plan shall be subject to the terms and conditions set forth in Section 6.1. NQOs shall be also subject to the terms and conditions set forth in Section 6.2, but not those set forth in Section 6.3. ISOs shall also be subject to the terms and conditions set forth in Section 6.3, but not those set forth in Section 6.2. 6.1 Terms and Conditions to Which All Options Are Subject. All Options granted under this Plan shall be subject to the following terms and conditions: 6.1.1 Changes in Capital Structure. Subject to Section 6.1.2, if the stock of the Company is changed by reason of a stock split, reverse stock split, stock dividend, or recapitalization, combination or reclassification, appropriate adjustments shall be made by the Board in (a) the number and class of shares of stock subject to this Plan and each Option outstanding under this Plan, and (b) the exercise price of each outstanding Option; provided, however, that the Company shall not be required to issue fractional shares as a result of any such adjustments. Each such adjustment shall be subject to approval by the Board in its sole discretion. 6.1.2 Corporate Transactions. In the event of the proposed dissolution or liquidation of the Company, the Administrator shall notify each optionee at least 30 days prior to such proposed action. To the extent not previously exercised, all Options will terminate immediately prior to the consummation of such proposed action. In the event of a merger or consolidation of the Company with or into another corporation or entity in which the Company does not survive, or in the event of a sale of all or substantially all of the assets of the Company in which the shareholders of the Company receive securities of the acquiring entity or an affiliate thereof, all Options shall be assumed or equivalent options shall be substituted by the successor corporation (or other entity) or a parent or -3- 33 subsidiary of such successor corporation (or other entity). In the event that such successor does not agree to assume the Options or to substitute equivalent options therefor, unless the Administrator shall determine otherwise, the Options will expire upon such event. 6.1.3 Time of Option Exercise. Subject to Section 5, Options granted under this Plan shall be exercisable (a) immediately as of the effective date of the stock option agreement granting the Option, or (b) in accordance with a schedule related to the date of the grant of the Option, the date of first employment, or such other date as may be set by the Administrator (in any case, the "Vesting Base Date") and specified in the written stock option agreement relating to such Option; provided, however, that the right to exercise an Option must vest at the rate of at least 20% per year over five years from the date the option was granted. In any case, no Option shall be exercisable until a written stock option agreement in form satisfactory to the Company is executed by the Company and the optionee. 6.1.4 Option Grant Date. Except in the case of advance approvals described in Section 5(d), the date of grant of an Option under this Plan shall be the date as of which the Administrator approves the grant. 6.1.5 Nonassignability of Option Rights. No Option granted under this Plan shall be assignable or otherwise transferable by the optionee except by will or by the laws of descent and distribution. During the life of the optionee, an Option shall be exercisable only by the optionee. 6.1.6 Payment. Except as provided below, payment in full, in cash, shall be made for all stock purchased at the time written notice of exercise of an Option is given to the Company, and proceeds of any payment shall constitute general funds of the Company. At the time an Option is granted or exercised, the Administrator, in the exercise of its absolute discretion after considering any tax or accounting consequences, may authorize any one or more of the following additional methods of payment: (a) Acceptance of the optionee's full recourse promissory note for all or part of the Option price, payable on such terms and bearing such interest rate as determined by the Administrator (but in no event less than the minimum interest rate specified under the Code at which no additional interest would be imputed), which promissory note may be either secured or unsecured in such manner as the Administrator shall approve (including, without limitation, by a security interest in the shares of the Company); and (b) Delivery by the optionee of Common Stock already owned by the optionee for all or part of the Option price, provided the value (determined as set forth in Section 6.1.11) of such Common Stock is equal on the date of exercise to the Option price, or such portion thereof as the optionee is authorized to pay by delivery of such stock; provided, however, that if an optionee has exercised any portion of any Option granted by the Company by delivery of Common Stock, the optionee may not, within six months following such exercise, exercise any Option granted under this Plan by delivery of Common Stock without the consent of the Administrator. -4- 34 6.1.7 Termination of Employment. Except as otherwise approved by the Administrator in its absolute discretion, if for any reason other than death or permanent and total disability, an optionee ceases to be employed by the Company or any of its Affiliates (such event being called a "Termination"), Options held at the date of Termination (to the extent then exercisable) may be exercised in whole or in part at any time within three months of the date of such Termination, (but in no event after the Expiration Date); provided, that if such exercise of the Option would result in liability for the optionee under Section 16(b) of the Exchange Act, such Option shall terminate at such later date as is fixed by the Administrator (but in no event after the Expiration Date). If an optionee dies or becomes permanently and totally disabled (within the meaning of Section 22(e)(3) of the Code) while employed by the Company or an Affiliate or within the period that the Option remains exercisable after Termination, Options then held (to the extent then exercisable) may be exercised, in whole or in part, by the optionee, by the optionee's personal representative or by the person to whom the Option is transferred by devise or the laws of descent and distribution, at any time within six months after the death or six months after the permanent and total disability of the optionee (but in no event after the Expiration Date). For purposes of this Section 6.1.7, "employment" includes service as a director or consultant. For purposes of this Section 6.1.7, an optionee's employment shall not be deemed to terminate by reason of sick leave, military leave or other leave of absence approved by the Administrator, if the period of any such leave does not exceed 90 days or, if longer, if the optionee's right to reemployment by the Company or any Affiliate is guaranteed either contractually or by statute. 6.1.8 Repurchase of Stock. At the option of the Administrator, the stock to be delivered pursuant to the exercise of any Option granted to a director, employee or consultant under this Plan may be subject to a right of repurchase in favor of the Company with respect to any director, employee or consultant whose director, employment, or consulting relationship with the Company is terminated. Such right of repurchase shall be at the Option exercise price and (i) shall lapse at the rate of at least 20% per year over five years from the date the Option is granted (without regard to the date it becomes exercisable), and must be exercised for cash or cancellation of purchase money indebtedness within 90 days of such termination and (ii) if the right is assignable by the Company, the assignee must pay the Company upon assignment of the right (unless the assignee is a 100% owned subsidiary of the Company or is an Affiliate) cash equal to the difference between the Option exercise price and the value (determined as set forth in Section 6.1.11) of the stock to be purchased if the Option exercise price is less than such value. Shares repurchased by the Company pursuant to the Company's right of repurchase are not again available for grant under the Plan. Determination of the number of shares subject to any such right of repurchase shall be made as of the date the director's director relationship with, employee's employment by, or consultant's consulting relationship with, the Company terminates, not as of the date that any Option granted to such director, employee or consultant is thereafter exercised. 6.1.9 Withholding and Employment Taxes. At the time of exercise of an Option or at such other time as the amount of such obligations becomes determinable (the "Tax Date"), the optionee shall remit to the Company in cash all applicable -5- 35 federal and state withholding and employment taxes. If authorized by the Administrator in its sole discretion after considering any tax or accounting consequences, an optionee may elect to (i) deliver a promissory note on such terms as the Administrator deems appropriate, (ii) tender to the Company previously owned shares of Stock or other securities of the Company, or (iii) have shares of Common Stock which are acquired upon exercise of the Option withheld by the Company to pay some or all of the amount of tax that is required by law to be withheld by the Company as a result of the exercise of such Option. Any limitations may be waived (or additional limitations may be imposed) by the Administrator, in its sole discretion, if the Administrator determines that limitations are not required (or that such additional limitations are required) in order that the transaction shall be exempt from Section 16(b) of the Exchange Act pursuant to Rule 16b-3, or any successor rule thereto. In addition, any limitations may be waived by the Administrator, in its sole discretion, if the Administrator determines that Rule 16b-3, or any successor rule thereto, is not applicable to the exercise of the Option by the optionee or for any other reason. Any securities tendered or withheld in accordance with this Section 6.1.9 shall be valued by the Company as of the Tax Date. 6.1.10 Other Provisions. Each Option granted under this Plan may contain such other terms, provisions, and conditions not inconsistent with this Plan as may be determined by the Administrator, and each ISO granted under this Plan shall include such provisions and conditions as are necessary to qualify the Option as an "incentive stock option" within the meaning of Section 422 of the Code. 6.1.11 Determination of Value. For purposes of the Plan, the value of Common Stock or other securities of the Company shall be determined as follows: (a) If the stock of the Company is listed on any established stock exchange or a national market system, including without limitation the National Market System of the National Association of Securities Dealers, Inc. Automated Quotation System, its fair market value shall be the closing sales price for such stock or the closing bid if no sales were reported, as quoted on such system or exchange (or the largest such exchange) for the date the value is to be determined (or if there are no sales for such date, then for the last preceding business day on which there were sales), as reported in The Wall Street Journal or similar publication. (b) If the stock of the Company is regularly quoted by a recognized securities dealer but selling prices are not reported, its fair market value shall be the mean between the high bid and low asked prices for the stock on the date the value is to be determined (or if there are no quoted prices for the date of grant, then for the last preceding business day on which there were quoted prices). (c) In the absence of an established market for the stock, the fair market value thereof shall be determined in good faith by the Administrator, with reference to the Company's net worth, prospective earning power, dividend-paying capacity, and other relevant factors, including the goodwill of the Company, the economic -6- 36 outlook in the Company's industry, the Company's position in the industry and its management, and the values of stock of other corporations in the same or a similar line of business. 6.1.12 Option Term. Subject to Section 6.3.4, no Option shall be exercisable more than ten years after the date of grant, or such lesser period of time as is set forth in the stock option agreement (the end of the maximum exercise period stated in the stock option agreement is referred to in this Plan as the "Expiration Date"). 6.1.13 Exercise Price. The exercise price of any Option granted to any person who owns, directly or by attribution under the Code currently Section 424(d), stock possessing more than ten percent of the total combined voting power of all classes of stock of the Company or of any Affiliate (a "Ten Percent Stockholder") shall in no event be less than 110% of the fair market value (determined in accordance with Section 6.1.11) of the stock covered by the Option at the time the Option is granted. 6.2 Terms and Conditions to Which Only NQOs Are Subject. Options granted under this Plan which are designated as NQOs shall be subject to the following terms and conditions: 6.2.1 Exercise Price. Except as set forth in Section 6.1.13, the exercise price of a NQO shall be not less than 85% of the fair market value (determined in accordance with Section 6.1.11) of the stock subject to the Option on the date of grant. 6.3 Terms and Conditions to Which Only ISOs Are Subject. Options granted under this Plan which are designated as ISOs shall be subject to the following terms and conditions: 6.3.1 Exercise Price. Except as set forth in Section 6.1.13, the exercise price of an ISO shall be determined in accordance with the applicable provisions of the Code and shall in no event be less than the fair market value (determined in accordance with Section 6.1.11) of the stock covered by the Option at the time the Option is granted. 6.3.2 Disqualifying Dispositions. If stock acquired by exercise of an ISO granted pursuant to this Plan is disposed of in a "disqualifying disposition" within the meaning of Section 422 of the Code, the holder of the stock immediately before the disposition shall promptly notify the Company in writing of the date and terms of the disposition and shall provide such other information regarding the Option as the Company may reasonably require. 6.3.3 Grant Date. If an ISO is granted in anticipation of employment as provided in Section 5(d), the Option shall be deemed granted, without further approval, on the date the grantee assumes the director, employment or consultancy relationship forming the basis for such grant, and, in addition, satisfies all requirements of this Plan for Options granted on that date. -7- 37 6.3.4 Term. Notwithstanding Section 6.1.12, no ISO granted to any Ten Percent Stockholder shall be exercisable more than five years after the date of grant. 7. MANNER OF EXERCISE (a) An optionee wishing to exercise an Option shall give written notice to the Company at its principal executive office, to the attention of the officer of the Company designated by the Administrator, accompanied by payment of the exercise price as provided in Section 6.1.6. The date the Company receives written notice of an exercise hereunder accompanied by payment of the exercise price will be considered as the date such Option was exercised. (b) Promptly after receipt of written notice of exercise of an Option, the Company shall, without stock issue or transfer taxes to the optionee or other person entitled to exercise the Option, deliver to the optionee or such other person a certificate or certificates for the requisite number of shares of stock. An optionee or permitted transferee of an optionee shall not have any privileges as a shareholder with respect to any shares of stock covered by the Option until the date of issuance (as evidenced by the appropriate entry on the books of the Company or a duly authorized transfer agent) of such shares. 8. RELATIONSHIP OF PARTICIPANT Neither the adoption of this Plan nor the grant of any Option hereunder shall (i) confer upon any employee any right to continued employment nor shall it interfere in any way with the right of the Company or an Affiliate to terminate the employment of any employee at any time; or (ii) confer upon any consultant any right to a continued consultancy relationship nor shall it interfere in any way with the right of the Company or an Affiliate to terminate the consultancy relationship of any consultant at any time; or (ii) confer upon any participant any right with respect to continuation of the participant's membership on the Board or shall interfere in any way with provisions in the Company's Articles of Incorporation and Bylaws relating to the election, appointment, terms of office, and removal of members of the Board. 9. FINANCIAL INFORMATION The Company shall provide to each optionee during the period such optionee holds an outstanding Option, and to each holder of Common Stock acquired upon exercise of Options granted under the Plan for so long as such person is a holder of such Common Stock, a balance sheet and income statement of the Company at least annually as prepared either by the Company or independent certified public accountants of the Company. Such financial statements shall be delivered as soon as practicable following the end of the Company's fiscal year. 10. CONDITIONS UPON ISSUANCE OF SHARES Shares of Common Stock shall not be issued pursuant to the exercise of an Option unless the exercise of such Option and the issuance and delivery of such shares -8- 38 pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act of 1933, as amended (the "Securities Act"). 11. NONEXCLUSIVITY OF THE PLAN The adoption of the Plan shall not be construed as creating any limitations on the power of the Company to adopt such other incentive arrangements as it may deem desirable, including, without limitation, the granting of stock options other than under the Plan. 12. AMENDMENTS TO PLAN The Board may at any time amend, alter, suspend or discontinue this Plan or any Option. Without the consent of an optionee, no amendment, alteration, suspension or discontinuance may adversely affect outstanding Options except to conform this Plan and ISOs granted under this Plan to the requirements of federal or other tax laws relating to incentive stock options. No amendment, alteration, suspension or discontinuance shall require shareholder approval unless (a) shareholder approval is required to preserve incentive stock option treatment for federal income tax purposes, (b) for so long as the Company has a class of equity securities registered under Section 12 of the Exchange Act, shareholder approval is required to meet the exceptions provided by Rule 16b-3, or any successor rule thereto, or (c) the Board otherwise concludes that shareholder approval is advisable. 13. EFFECTIVE DATE OF PLAN This Plan shall become effective upon adoption by the Board, provided, however, that no Option shall be exercisable unless and until written consent of the shareholders of the Company, or approval of shareholders of the Company voting at a validly called shareholders' meeting, is obtained within 12 months after adoption by the Board. If such shareholder approval is not obtained within such time, Options granted hereunder shall terminate and be of no force and effect from and after expiration of such 12 month period.
