                  Committee of the Board, assuming he satisfies applicable legal
                  requirements and listing standards. The Nominating and
                  Corporate Governance Committee will use its reasonable best
                  efforts to appoint one additional member to the Board as
                  promptly as practicable, who shall be unanimously approved by
                  the committee. RIP agreed to withdraw its nomination letter
                  for the 2008 annual meeting.

                  Pursuant to the Settlement Agreement, the Reporting Persons
                  agreed to vote in favor of the Board's slate of nominees at
                  the 2008 annual meeting and all further annual meetings so
                  long as the slate includes Mr. Riley (or his designated
                  replacement) and he has consented to be on such slate. The
                  Reporting Persons also agreed to vote in favor of the
                  proposals submitted by the Board at the 2008 annual meeting
                  and all further annual meetings so long as the slate includes
                  Mr. Riley (or his designated replacement) and he has consented
                  to be on such slate and provided that Mr. Riley (or his
                  designated replacement) has voted in favor of such proposal as
                  a member of the Board.

                  Pursuant to the Settlement Agreement, the Reporting Persons
                  agreed until at least June 30, 2009 and so long as Mr. Riley
                  (or his designated replacement) serves on the Board to various
                  standstill provisions. Under the standstill provision, subject
                  to specified exceptions, the Reporting Persons and their

                  propose to acquire any of the Company's voting securities (or
                  beneficial ownership thereof), or rights or options to acquire
                  any voting securities if it would result in the Reporting

                  of the then outstanding Common Stock; (iii) engage in any
                  solicitation of proxies or consents to vote in opposition to
                  the recommendation of the Board; (iv) knowingly seek to
                  influence any person with respect to the voting of any

                  the Company's Amended and Restated Articles of Incorporation
                  or Amended and Restated Bylaws except as may be approved by
                  the Board; (viii) grant any proxy rights with respect to the
                  Common Stock to any person not designated by the Company; (ix)
                  call or seek to have called any meeting of the shareholders of
                  the Company; (x) propose any matter for submission to a vote
                  of the shareholders of the Company; (xi) execute any written
                  consents, waiver or demand with respect to the Common Stock;
                  (xii) unless required by law, make any public disclosure,
                  announcement or statement in support of any non-Issuer proxy
                  solicitation, concerning the matters described in (i) through
                  (x) above, or negatively commenting upon the Issuer; and
                  (xiii) enter into any agreements with any third party with
                  respect to any of the foregoing. The standstill provisions
                  terminate when Mr. Riley (or his designated replacement) first
                  ceases to serve on the Board, but no earlier than June 30,
                  2009.

                  The Settlement Agreement may be terminated by the
                  non-breaching party in the event of a material breach by any
                  party, subject to a five-business day cure period. The
                  Settlement Agreement will also be terminated if the Company's

                  prior to June 1, 2008 with the Mr. Riley as a nominee and the
