        Company. In the event that the Company consummates a change of control
        transaction, 50% of any unvested options held by the Company's officers and
        directors who are parties to such agreements shall become fully vested and
        immediately exercisable and repurchase rights retained by the Company with
        respect to 50% of the restricted stock held by the Company&#8217;s officers and
        directors who are parties to such agreements shall immediately lapse. In

        of control transaction, 1/12th of the remaining unvested options held by
        the

        by
        such officer or director shall become fully vested and immediately exercisable

        Company&#8217;s indemnification agreements contain provisions which may require the

        or
        service as officers or directors (other than liabilities arising from willful

        a
        result of any proceeding against them as to which they could be indemnified.
        Insofar as indemnification for liabilities arising under the Securities Act
        of
        1933 may be permitted to directors, officers or persons controlling the Company
        pursuant to the foregoing provisions, the Company has been informed that
        in the
        opinion of the SEC such indemnification is against public policy as expressed
        in
        the Securities Act and is therefore unenforceable.</font></div>

Item
                  5.02
Departures
                  of Directors or Principal Officers; Election of Directors;
Appointment
                  of Principal Officers.
On
        September 29, 2005, the Board of Directors (the "Board") of RITA Medical
        Systems, Inc. (the "Company"), upon the recommendation of the Board's
        Nominating/Corporate Governance Committee, elected Steve LaPorte, age 55,
        as a
        Class I director of the Company to serve until the Company's 2007 annual
        meeting
        of stockholders and a member of the Board's Nominating/Corporate Governance
        Committee.
In
        connection with Mr. LaPorte's election, pursuant to the terms of the Company's
        2000 Directors' Stock Option Plan, Mr. LaPorte automatically received a
        nonstatutory stock option to purchase 35,000 shares of the Company common
        stock.
        This option vests at a rate of 1/36th of the total number of shares subject
        to
        such option per month.
The
        Company has entered into its standard form of change of control agreement
        and
        indemnification agreement with Mr. LaPorte. The Company's change of control
        agreements provide the following benefits upon the sale or merger of the
        Company. In the event that the Company consummates a change of control
        transaction, 50% of any unvested options held by the Company's officers and
        directors who are parties to such agreements shall become fully vested and
        immediately exercisable and repurchase rights retained by the Company with
        respect to 50% of the restricted stock held by the Company's officers and
        directors who are parties to such agreements shall immediately lapse. In
        addition, on each one month anniversary following the effective date of a
        change
        of control transaction, 1/12th of the remaining unvested options held by
        the
        Company's officers and directors who are parties to such agreements shall become
        fully vested and immediately exercisable and repurchase rights retained by
        the
        Company with respect to 1/12th of any remaining restricted stock held by
        the
        Company's officers and directors who are parties to such agreements shall
        immediately lapse. If the officer or director is involuntarily terminated
        within
        12 months after the change of control transaction, all unvested options held
        by
        such officer or director shall become fully vested and immediately exercisable
        and all repurchase rights retained by the Company with respect to the restricted
        stock held by such officer or director shall immediately lapse. If the officer
        or director voluntarily resigns or is terminated for cause after the change
        of
        control, then the officer or director is not entitled to any acceleration
        of the
        vesting of options or lapse of repurchase rights with respect to restricted
        stock.
The
        Company's indemnification agreements contain provisions which may require the
        Company, among other things, to indemnify the Company's officers and directors
        against a number of liabilities that may arise by reason of their status
        or
        service as officers or directors (other than liabilities arising from willful
        misconduct of a culpable nature) and to advance their expenses incurred as
        a
        result of any proceeding against them as to which they could be indemnified.
        Insofar as indemnification for liabilities arising under the Securities Act
        of
        1933 may be permitted to directors, officers or persons controlling the Company
        pursuant to the foregoing provisions, the Company has been informed that
        in the
        opinion of the SEC such indemnification is against public policy as expressed
        in
        the Securities Act and is therefore unenforceable.
