          (e) During the last five years, none of the Reporting Persons or, to
the best of their  knowledge,  any of their  directors or executive  officers,

prohibiting  or mandating  activities  subject to federal or state  securities
laws or finding any violation with respect to such laws except as noted below:

          In July 2005,  Merrill Lynch reached an agreement in principal  with
the NYSE pursuant to which  Merrill  Lynch,  without  admitting or denying the
allegations,  consented to a settlement that includes  findings with regard to
certain matters  relating to the failure to deliver  prospectuses  for certain
auction  rate  preferred  shares and  open-end  mutual  funds;  the failure to
deliver product descriptions with regard to certain exchange-traded funds; the
failure to ensure that proper  registration  qualifications  were obtained for
certain personnel;  issues with regard to the retention,  retrieval and review
of e-mails;  isolated lapses in branch office  supervision;  late reporting of
certain events such as customer  complaints and  arbitrations;  the failure to
report  certain  complaints  in quarterly  reports to the NYSE due to a system
error; and partial non-compliance with Continuing Education requirements.  The
settlement resulted in a payment of $10 million to the NYSE.
