     4J. RIGHTS OF MANAGEMENT GROUP. The Management Investors have entered into
this Agreement on their own behalf and, for the purposes of Section 2 of this
Agreement, on behalf of the participants in the Company's 2002 Management Equity
Plan (the "MANAGEMENT GROUP") but the Management Investors shall be entitled in
their absolute discretion to exercise (or omit to do so) all powers, authorities
and rights granted in Section 2 of this Agreement without recourse to or
consultation with the Management Group. No member of the Management Group shall
have any claim or right against the Management Investors on account of the
manner in which he has exercised or failed to exercise any of the said powers,
rights and authorities and each member of the Management Group waives any and
all rights which he may hereafter have or acquire as a result of the exercise or
manner of exercise or failure to exercise any of the said powers, rights and
authorities whether or not in so doing the Management Investors have acted
recklessly or negligently. In no event shall any member of the Management Group
(other than the Management Investors) have any right themselves to bring an
action or suit against the Company, any MDCP Co-Investor or any other Person for
breach of this Agreement.

     4K. TERMINATION. Other than paragraph 1I (which shall terminate upon the
earlier of the date that the Minimum Investment Condition is no longer satisfied
and a Sale of the Company), the provisions of this Agreement shall terminate
automatically upon the earlier of (i) a Listing and (ii) a Sale of the Company.
