               the conduct of his duties hereunder, (iv) habitual absenteeism,

               this Agreement or (vii) the willful and material failure or

               supervisor. The payment to the Executive of the severance payment
               described in this Section 5(b) will discharge all of the
               Company's obligations to the Executive.

        c.     This Agreement may be terminated by the Company at any time
               without Justifiable Cause provided that the Company shall pay the

               in Section 6) to the Executive. If such termination takes place
               in the first year of the Executive's employment with the company,
               the incentive stock option will vest at 1/48th per month, and the

7.      Notwithstanding anything set forth in this Section 7, upon the
        Executive's involuntary termination of employment from the Company (for
        any reason other than for Justifiable Cause) on or after an Acquisition
        (as defined below), the 100,000 shares of Common Stock described in
        Section 4 above shall be fully and immediately exercisable. For purposes
        of this Section 7, an Acquisition shall be defined as a merger,
        reorganization, or sale of all or substantially all of the assets for
        the Company in which shareholders of the Company immediately prior to
        the transaction possess less than fifty percent (50%) of the voting
        power of the surviving entity (or its parent) immediately after the
        transaction. The resignation of the Executive after a Constructive
        Termination (as defined below) shall be treated as an involuntary
        termination of employment under this Section 7. For purposes of this
        Section 7, a Constructive termination shall mean a material reduction in
        salary or benefits, a material change in responsibilities, a requirement
        to relocate, except for office relocations that would not increase the
        Executive's one-way commute distance by more than thirty-five (35)
        miles.

8.      The Executive will be eligible to participate in any insurance or other
        benefit plan as may be sponsored or maintained by the Company from time
        to time for its employees. Cardiac Pathways currently offers medical,
        dental, vision, life and long-term disability insurance, a 401k,
        flexible benefits and an Employee stock purchase plan.

9.      This offer is contingent upon Cardiac Pathways receiving the enclosed
        Proprietary Information agreement which must be executed by you.

10.     In accordance with Federal immigration law, on your first day of
        employment, we will need to see documents proving your identity and
        eligibility to work in the United States. Documents which can satisfy
        these requirements are a valid driver's license and a social security
        card or a United States passport.

11.     Your employment is at will, as defined under applicable law. If your
        employment terminates for any reason, you shall not be entitled to any
        payments, benefits, damages, awards or compensation other than as
        provided above, or as otherwise be available in accordance with the
        Company's established employee plans and policies at the time of
        termination.

12.     If the terms of this letter and the enclosed Proprietary Information
        agreement are agreeable, please sign and return one copy of this letter
        and the agreement to our Human Resources Department. We look forward to
        working with you at Cardiac
