REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS During fiscal 1995, management compensation issues were reviewed by the Compensation Committee which consisted of all members of the Board except Dr. Harvey. The Board had an Option Committee made up of two outside directors who administered the Company's stock option plans. In 1996, the Option Committee was discontinued and the Compensation Committee was renamed the Compensation and Option Committee. The function of the Compensation and Option Committee is to review and recommend 7 10 management compensation to the Board. The Compensation Committee and the Option Committee each met one time in 1995. 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 in large 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. Due to the high cost of housing relative to other parts of the country, and the correspondingly substantial relocation expenses for out-of-state executives, the Company's recruiting efforts generally have been focused on experienced personnel who are already located in the Bay Area. 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 Stock Option Plan 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 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 1995 tax year, all compensation paid by the Company in 1995 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 1995 were FDA approval of the Company's VAD System and closing of an interim round of financing to support operations. 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 November 1995, the base annual salaries of three Company executives were increased by 10% after a two year salary freeze. 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 Compensation. Generally, the non-employee 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 members of the Board then meet in the absence of the Chief Executive Officer and other employee members of the Board, if any, to discuss the performance of the Chief Executive Officer. 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 1995, 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 or 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 30, 1995, 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 40,000 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 18,824 shares of Common Stock for an aggregate purchase price of $50,000. In March 1996, Bradley Resources Company converted its Convertible Promissory Notes into 30,675 shares of Common Stock and exercised its warrant to purchase 19,139 shares of Common Stock at an exercise price of $1.50 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 1994 and 1995, sales to COBE represented approximately 20% and 26%, respectively, of Thoratec's net revenue. In 1995, Thoratec modified its distributor agreement with COBE and appointed Arrow International as its distributor in most of the former COBE countries. In March 1996, Thoratec 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, 1990.

FISCAL YEAR ENDING DECEMBER. PROPOSAL TWO APPROVAL OF THE 1996 STOCK OPTION PLAN At the Annual Meeting, the shareholders are being asked to approve Thoratec's 1996 Stock Option Plan (the "1996 Option Plan"). DESCRIPTION OF THE 1996 OPTION PLAN The purposes of the 1996 Option Plan are to: encourage selected employees and consultants to improve operations and increase profits of the Company; encourage selected employees and consultants to accept or continue employment or association with the Company or its affiliates; and increase the interest of selected employees 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 1996 Option Plan. Only full-time employees of the Company, currently approximately 65 people, are eligible to receive ISOs or NQOs. Consultants are eligible to receive only NQOs. 10 13 Options granted expire 10 years after the date of grant, or earlier, in the event of termination of the optionee's employment or consulting 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. The exercisability of 115,000 options granted, as of March 30, 1996, under the 1996 Option Plan and the 1,385,000 shares available for grant thereunder are subject to shareholder approval. The exercisability of a grant of 1,000,000 NQOs made to Mr. Grossman is not subject to shareholder approval. 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 1996 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 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 1996 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 1996 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 1996 Option Plan to comply with Section 422 of the Code, the shareholders of the Company must approve any amendment, alteration or discontinuance of the 1996 Option Plan that would (i) increase the total number of shares reserved under the 1996 Option Plan, (ii) change the minimum price terms for option exercise, (iii) change the class of employees and consultants eligible to participate in the 1996 Option Plan, (iv) extend the maximum option exercise period or (v) materially increase the benefits accruing to participants under the 1996 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 1996 Option Plan. PROPOSAL; BOARD RECOMMENDATION Shareholders are being asked to approve the 1996 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 1996 Option Plan. The Board recommends a vote "FOR APPROVAL" of the proposal. PROPOSAL THREE APPROVAL OF NONEMPLOYEE DIRECTORS STOCK OPTION PLAN At the Annual Meeting, the shareholders are being asked to approve Thoratec's 1996 Nonemployee Directors Stock Option Plan (the "Directors Option Plan"). DESCRIPTION OF THE 1996 NONEMPLOYEE DIRECTORS STOCK OPTION PLAN In 1996, the Board adopted the Directors Option Plan, subject to shareholder approval. A total of 450,000 shares of the Company's Common Stock have been reserved for issuance under the Directors Option Plan, none of which has as yet been issued. 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. 11 14 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"). Each person who is newly elected or appointed as an Eligible Outside Director on or after the annual meeting of shareholders in 1996 will be granted an option to purchase 10,000 shares of Common Stock on the effective date of such initial election or appointment. Thereafter, each Eligible Outside Director (including the existing outside directors) generally will be granted an option to purchase 5,000 shares of Common Stock on the date of the first meeting of the Board of Directors following the annual shareholders 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 of Directors. Each option granted under the Directors Option Plan is exercisable in full six months after the date of grant. The Company has the right of repurchase 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 the 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 of Directors 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 any time, 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 certain other circumstances as the Board may deem advisable to comply with such laws and regulations. In addition, the provisions of the plan governing who is granted options, the number of shares covered by each 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 Internal Revenue Code of 1986 or the Employee Retirement Income Security Act of 1974. The following table shows, based on the current composition of the Board, the number of options which will be granted annually 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) ------------------- All executive officers as a group.......................................... 0 All directors who are not executive officers as a group.................... 25,000 All employees (other than executive officers) as a group................... 0 - --------------- (1) All options granted at fair market value as of the date of grant. It is estimated that 50,000 options will be granted in 1996. Under the 1996 Option Plan, nonemployee directors are not eligible to receive options. The Company believes it important that directors have meaningful equity ownership in Thoratec. The reason for creating a 12 15 nondiscretionary option plan for nonemployee directors and limiting their participation in the 1996 Option Plan is so that outside directors will be able to administer such plans (and any subsequently approved discretionary stock plans) in the future under rules of the Securities and Exchange Commission. 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 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 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 AMTI in the year of exercise. Special rules regarding the time 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 to 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, and 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 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 13 16 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 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. 14 17 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. PROPOSAL FOUR APPROVAL OF AMENDMENT OF ARTICLES OF INCORPORATION At the Annual Meeting, the shareholders are being asked to approve an amendment to the Company's Articles of Incorporation to effect a one for three reverse stock split of the Company's Common Stock (the "Reverse Split"). DESCRIPTION OF PROPOSAL The Board has approved an amendment of the Company's Articles of Incorporation to effect a reverse stock split, pursuant to which each three shares of Common Stock of the Company will become one share of Common Stock. The Reverse Split will take effect after it is approved by the shareholders of the Company and after filing with the Secretary of State of the State of California (the "Effective Date"). Even if the Reverse Split is approved by the shareholders it is within the discretion of the Board of Directors to not carry out the Reverse Split. The purpose of the Reverse Split is to adjust the price of the Common Stock and the number of outstanding shares to a level which the Board of Directors believes, after consultation with its financial advisors, will facilitate future public equity financings and the acquisition of Common Stock by institutional investors. The Reverse Split will not affect the relative holdings of the Company's security holders. As a result of the Reverse Split, the 46,726,055 shares of Common Stock outstanding on March 30, 1996 will become approximately 15,575,352 shares of Common Stock and any other shares issued prior to the Effective Date will be similarly adjusted. No fractional shares will be issued upon the Reverse Split. In lieu thereof, the Company will pay each holder of a fractional interest an amount in cash equal to the value of such fractional interest on the Effective Date. The number of authorized shares of Common Stock will remain 100,000,000. In addition, on the Effective Date each three options to purchase Common Stock outstanding on the Effective Date will be adjusted so that the number of shares of Common Stock purchasable thereunder shall be one (and corresponding adjustments will be made to the number of shares vested under each outstanding option) and the exercise price of each option shall be multiplied by three. On the Effective Date, the outstanding warrant to purchase the Company's Common Stock shall be adjusted so that the number of shares of Common Stock purchasable upon exercise of such warrant shall be reduced from 2 million shares to 666,667 shares and the exercise price of the warrant shall be increased from $.001 per share to $.003 per share. PROPOSAL: BOARD RECOMMENDATION Shareholders are being asked to approve the proposed amendment to the Company's Articles of Incorporation. The affirmative vote of the holders of a majority of the outstanding shares of the Company is required for approval. The Board recommends a vote "FOR APPROVAL" of the proposal. 15 18 PROPOSAL FIVE AMENDMENT OF BYLAWS The shareholders are being asked to approve an amendment to the Bylaws of the Company to set the size of the Board of Directors between five to nine directors, with the exact number to be fixed by the Board. AMENDMENT TO BYLAWS The Company's Bylaws currently provide that the Board of Directors shall have from four to seven members with the exact number to be fixed by the Board of Directors. The proposed amendment to the Bylaws would provide that the Company shall have five to nine directors, with the exact number to be fixed by the Board of Directors. Now that the Company has an FDA approved VAD System, the Company believes that the Board of Directors should have the flexibility to increase the size of the Board to augment the experience represented on the Board in areas such as marketing and manufacturing when and if suitable candidates are available. PROPOSAL; BOARD RECOMMENDATION Shareholders are being asked to approve the proposed amendment to the Bylaws. The affirmative vote of the holders of a majority of the outstanding shares of the Company is required for approval. The Board recommends a vote "FOR APPROVAL" of the proposal. INDEPENDENT AUDITORS The Board has selected Deloitte & Touche LLP as independent auditors to audit the financial statements of the Company for the 1996 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 PROPOSALS Proposals of shareholders of the Company which are intended to be presented at the Company's 1997 meeting of shareholders must be received by the Secretary of the Company no later than January 16, 1997 in order to be included in the proxy soliciting material relating to that meeting.
