     Any Director Designee may be removed from the Board of Directors in the
manner allowed by law and Tremisis's governing documents except that each
Stockholder agrees that he, she or it will not, as a stockholder, vote for the
removal of any director who is a member of Group of which such Stockholder is

exercising his or her fiduciary duties and responsibilities, it being agreed and
understood that this Agreement shall apply to each Stockholder solely in his or
her capacity as a stockholder of Tremisis and shall not apply to his or her
actions, judgments or decisions as a director or officer of Tremisis if he or
she is such a director or officer.

     SECTION 1.06 Transfer of Shares. If a member of the RAM Group desires to
transfer his, her or its Shares to a permitted transferee pursuant to the
Lock-Up Agreement of even date herewith executed by such member, or if a member
of the Founders Group desires to transfer his or its shares to a permitted
transferee pursuant to the Escrow Agreement dated as of May 12, 2004, it shall
be a condition to such transfer that the transferee agree to be bound by the
provisions of this Agreement. This Agreement shall in no way restrict the
transfer on the public market of Shares that are not subject to the Lock-Up
Agreement or the Escrow Agreement, and any such transfers on the public market
of Shares not subject to the provisions of the Lock-Up Agreement or the Escrow
Agreement, as applicable, shall be free and clear of the restrictions in this
Agreement.

or regulatory authority, domestic or foreign, except (i) for applicable
requirements, if any, of the Exchange Act, and (ii) where the failure to obtain
