Dear Mr.
Metcalf:
I am
responding on behalf of Joe Burgess to your letter of April 29,
2008. As you are aware, Mr. Burgess is travelling this
week.
It is
with regret that we must decline your invitation to participate at LIUNA’s
Investor Forum. Unfortunately, the short advance notice you provided
us does not allow our attendance. We have previously scheduled
meetings with our stockholders that extend beyond next week. We
regret that you did not mention the Investor Forum in your initial letter to
Messrs. Burgess and Woods on April 24, 2008 as we might have been able to
schedule our participation before we finalized our meeting
schedules.
We will,
however, be pleased to provide a Company statement that we request be read to
participants at the forum. Additionally, we welcome the opportunity
to speak directly to all Company stockholders participating at the
forum. We invite and encourage all those stockholders to contact
Innisfree M&A Incorporated, which is assisting Insituform in connection with
its proxy solicitation, at 888-750-5834. Innisfree will arrange a
time for any interested stockholder to speak with management of the
Company.
With
respect to your April 24 letter to Messrs. Burgess and Woods, we also welcome
the opportunity to meet with representatives of LIUNA at an appropriate time (I
note that there are many inaccurate statements in your April 24 letter, but we
will address them separately). We appreciate and value our relationships with
the labor unions that represent employees of this Company, including LIUNA, and
are always looking for ways to improve those relationships. Labor
unions represent many of the hard working, dedicated employees of this great
Company.
We
appreciate your time and understanding and look forward to hearing from you
soon. Please contact me if you have any questions or
comments.
Very truly
yours,
INSITUFORM
TECHNOLOGIES, INC.
