VESTING PROVISIONS

Paragraph SECOND is hereby amended, effective as of April 20, 2006, by revising
Paragraph (c) in its entirety to read as follows:

          (c) Except as otherwise provided in this Paragraph SECOND, if the
     Grantee shall cease to be an employee or a director of the Company or any
     Subsidiaries for any reason other than death, Total and Permanent
     Disability, Retirement or an involuntary termination of Participant's
     employment with or service as a director of the Company or any Subsidiaries
     (other than for Cause) at any time within 12 months following a Change in
     Control, the Restricted Shares shall be forfeited immediately. Upon the
     occurrence of an involuntary termination of Participant's employment with
     or service as a director of the Company or any Subsidiaries (other than for
     Cause) at any time within 12 months following a Change in Control, the
     Restricted Stock shall become 100% vested on such event and the
     restrictions on transfer shall lapse. For purposes of this Paragraph
     SECOND:

          "Cause" means the occurrence of any of the following events: (i) the
     commission by Participant of an act of willful misconduct in any material
     respect including, but not limited to, the willful violation of any
     material law, rule, regulation or cease and desist order applicable to
     Participant or the Company (other than a law, rule or regulation relating
     to a minor traffic violation or similar offense), or an act which
     constitutes a breach of a fiduciary duty owed to the Company by Participant
     involving personal profit; (ii) the commission by Participant of an act of
     dishonesty relating to the performance of Participant's duties, habitual
     unexcused absence from work, willful failure to perform duties in any
     material respect (other than any such failure resulting from Participant's
     incapacity due to physical or mental illness or disability), or gross
     negligence in the performance of duties resulting in damage or injury to
     the Company, its reputation or goodwill (provided, however, that in the
     event of Participant's willful failure to perform duties in any material
     respect, Participant shall be provided with written notice of such event
     and shall be provided with a reasonable opportunity, and in no event more
     than thirty (30) days, to cure such failure to perform his duties); or
     (iii) any felony conviction of Participant or any conviction involving
     dishonesty, fraud or breach of trust (other than for a minor traffic
     violation or similar offense), whether or not in the line of duty.

          "Change in Control" means the first to occur of any of the following
     events which occurs at any time after the Effective Date: (i) Any "person"
     (as the term is used in Sections 13(d) and 14(d) of the Exchange Act, other
     than a trustee or other fiduciary holding securities under an

<PAGE>

     executive benefit plan of the Company or any of its Subsidiaries, becomes
     the beneficial owner (as defined in Rule 13d-3 under the Exchange Act),
     directly or indirectly, of securities of the Company representing more than
     25% of the combined voting power of the Company's then outstanding
     securities; (ii) individuals who are members of the Board on the date of
     this Agreement (the "Incumbent Board") cease for any reason to constitute
     at least a majority of the Board, provided that any person becoming a
     director subsequent to the date of this Agreement in replacement for a
     director who has died or become disabled and whose election was approved by
     a vote of at least a majority of the directors comprising the Incumbent
     Board, or whose nomination for election by the Company's stockholders was
     approved by a nominating committee serving under an Incumbent Board, shall
     be considered a member of the Incumbent Board; (iii) a merger or
     consolidation of the Company with any other corporation or other business
     entity, other than a merger or consolidation which would result in the
     combined voting power of the Company's securities outstanding immediately
     prior thereto continuing to represent (either by remaining outstanding or
     by being converted into voting securities of the surviving entity) at least
     51% of the combined voting power of the securities of the Company or such
     surviving entity outstanding immediately after such merger or
     consolidation; or (iv) a sale or disposition by the Company of all or
     substantially all of the Company's assets.
