Dear Fellow Stockholder,

Steel  Partners  II, L.P. is the owner of  1,435,818  shares of common  stock of
Layne   Christensen   Company  ("LAYN"  or  the  "Company")  and  third  largest
stockholder  of LAYN. I am the managing  member of Steel Partners and a director
of LAYN. Steel Partners is asking for your support FOR its stockholder  proposal
included  in the  Company's  proxy  statement  for the 2005  annual  meeting  of
stockholders, which asks the LAYN board of directors to take the steps necessary
to declassify the LAYN board.  We believe that the annual election of the entire
board of directors  will give LAYN  stockholders  the most direct and  effective
voice in the governance of our company.

The Company's board is currently  divided into three classes,  each elected to a
three-year  term. Any single  director must face the  stockholders  and have his
performance  ratified  only once in three  years.  We  believe  sound  corporate
governance practices,  such as the annual election of directors, will impose the
level  of  management  accountability  necessary  to  help  insure  that  a good
performance record continues over the long term.

As a governance matter,  the classified board is a paternalistic  anachronism in
today's  investment  environment;  the underlying  premise is that  stockholders
could be stampeded  into ousting the entire board to the  detriment of their own
investment.  A classified  board will thus, in theory,  protect the stockholders
from their own folly. We believe this is nonsense, and that LAYN's stockholders,
a majority of whom are professional money managers, can make intelligent choices
on their own. Consider that, in 2004,  according to the Investor  Responsibility
Research Center,  stockholder proposals to end board classification received, on
average,  the favorable vote of 70.6% of the stockholder  votes cast. We believe
these votes have sent a clear message that public companies should not ignore.

In casting your vote,  please  remember  that this proposal is a request for the
board to act. LAYN's  stockholders  are unable to alter the classified  board on
their own - they can only act after  approval by the board,  and thereafter by a
supermajority  vote  of 80% of the  outstanding  shares  in a  separate  binding
proposal  if  made at the  discretion  of the  board.  Your  vote  is  therefore
critical.  LAYN's directors are your elected representatives.  Send them a clear
message that you desire  stockholder  empowerment  and basic good  governance by
voting FOR proposal 2 today.

Thank you for your support,
