**I.**  **Objective**    Thoratec’s Executive Incentive Plan, hereinafter referred to as EIP is intended to rewardexecutive personnel who significantly impact and influence Thoratec’s productivity inproportion to their accomplishment of specified objectives.    The purpose of the plan is to ensure maximum return to Thoratec by encouraging greaterinitiative, resourcefulness, teamwork and efficiency on the part of senior management whoseperformance and responsibilities directly affect company profits.    Awarding of the bonus will be based on accomplishing a set of annual objectives, determinedby the Chief Executive Officer (“CEO”) and the Board of Directors, typically at thebeginning of the year. Bonus determinations and payouts will take place after the financialstatements have been prepared for the fiscal year. **II.**  **Determination Of The Fund**    The availability of, and participants in, the fund will be set by the CEO and approved bythe Board of Directors as part of the annual budgeting process. **III.**  **Effective Date**    The effective date of this program is January 2, 2005, the beginning of the plan year, andwill continue in effect until December 31, 2005, or until terminated or amended by the Boardof Directors.

**V.**  **Incentive Objectives**    Objectives will be agreed to by the CEO with the Executive Officers reporting to him andwith concurrence by the Board of Directors as necessary. Generally, there will be a minimumof four upto a maximum of seven objectives, which will include two or more corporate financialobjectives. Each objective will be weighted according to its importance, which weight willdetermine the percentage of the bonus awarded for completion of that objective. (SeeSection VI below.)    After approval, copies of these goals must be submitted to the Vice President of HumanResources. **VI.**  **Bonus Opportunity and Award**    The award opportunity will be expressed as a percentage of the participant’s base salary atthe close of the fiscal year. The award will be approved by the Board of Directors or theCEO, and will be consistent with the participant’s peers within the company.    The amount that a participant actually receives for the full fiscal year will be based uponthe extent to which the set objectives have been achieved. The participant will receive apercentage of the total award opportunity corresponding to the percentage of each objectiveaccomplished and the weight assigned to the objective. Evaluations of performance againstmanagement and business plan objectives are made for the full year prior to fiscal year-endpayment. **VII.**  **Performance Goal and Payout**    In addition to your individual goals, everyone will have two company-oriented financialgoals that will be achieved according to the following guidelines:                           **Revenue**  **Cash Earnings***(1)*       Goal  Award  Goal  Award Threshold = to, or > $*   50% $*   50%Target = to, or > $*   100% $*   100%
    Note: If revenue is less than $* (95% of target), no payment is earned for thatobjective. If pre-bonus income is less than $* (85% of target), no payment is earned forthat objective. If actual results fall between threshold and target, interpolate betweenthem to get actual payout percentage. This percentage will be multiplied times the weightgiven the objective in your individual plan to determine the achievement. Quarterly revenueand cash earnings information may be released at the end of each quarter, after earningshave been disclosed to the public.
*(1)* Cash Earnings is defined as consolidated GAAP net income before extraordinaryitems and excluding the effect of amortization of goodwill and purchased intangibles, inprocess research and development, merger restructuring and unusual costs, stock-basedemployee compensation expense, income tax expense (benefit) and special incentive awards. * Amounts to be determined by the Compensation and OptionCommittee of the Board of Directors.
