Item 5. Other Events and Regulation FD Disclosure.

DATE FOR 2004 ANNUAL MEETING OF STOCKHOLDERS; STOCKHOLDER PROPOSALS

         The Company intends to hold its 2004 annual meeting of stockholders on
Wednesday, April 28, 2004.

         Our by-laws provide that, in order for a stockholder to nominate a
candidate for director at a meeting of stockholders, the stockholder must have
given timely notice thereof in writing to our Secretary. If the date of the
annual meeting is advanced or delayed by more than 30 days compared to the date
of the preceding year's annual meeting, which will be the case in 2004, notice
by the stockholder to be timely made must be received not later than the close
of business on the later of:

         o        the ninetieth day prior to the meeting, or

         o        the tenth day following the date on which the date set for the
                  meeting is first announced publicly.

         Any stockholder filing a notice of nomination must include the
information required by our by-laws.

         In order for a stockholder to bring other business before an annual
meeting of stockholders, the stockholder must have given timely notice thereof
in writing to our Secretary within the time limits described above. The notice
must include the information required by our by-laws.

         If a stockholder fails to notify us within the time limits described
above of an intent to present a nomination or proposal for a stockholder vote at
our 2004 annual meeting of stockholder, the Company will declare the nomination
or business to be not properly brought before the meeting and, therefore, the
nomination will be disregarded or the business will not be transacted. The
foregoing requirements are separate from and in addition to the requirements of
the Securities and Exchange Commission that a stockholder must meet to have a
proposal included in our proxy statement. We must receive stockholder proposals
intended to be presented at the 2004 annual meeting by January 29, 2004 in order
to be considered for inclusion in our proxy statement relating to such meeting.
