Mr. Leon van Kraayenburg

Houston, TX  77070


Dear Mr. van Kraayenburg:


At March 1, 2005 meetings of the Board of Directors of both EnerTeck Corporation
and EnerTeck  Chemical Corp., each Board accepted your resignations as Executive
Vice  President  and Chief  Financial  Officer,  as well as a  Director,  of its
respective Company, effective today, March 1, 2005.

The Inter Office Memo you have supplied  dated  February 10, 2005 and personally
delivered  to Mr.  Reese  on  February  14,  2005,  wherein  you  tendered  your
resignation as a Director of both Companies but left  unresolved  your status as
an officer of both  companies,  stipulates  that you are owed $19,000 in arrears
under your employment  agreement with EnerTeck  Chemical Corp.  Furthermore your
letter of February 24 wherein you  tendered  your  resignation  as an officer of
each  company  indicates  that  you are now owed a total  of  $26,081.51,  which
includes  claims for salary and unused earned  vacation days.  Please be advised
that the  Company  acknowledges  that you are due some  compensation  under this
employment  agreement with EnerTeck Chemical Corp. However, the Company disputes
the amount  that is claimed  due and  payable.  The Board has advised me that we
would be pleased to  discuss  your claim of amounts  owed and has asked that you
supply documentation to support your assertion.

Each of your employment  agreements stipulates that you are required to promptly
return,  after  resignation,  all  equipment  and  documents in your  possession
related to the business of both Companies. Please be advised that Mr. Reese will
be available the week of February 28th, 2005 at the EnerTeck  corporate  offices
to accept receipt of said equipment and documents.  You are further advised that
in  addition  to  the  equipment  and  documents  in  your  possession   related
specifically  to your  employment  with both EnerTeck  Corporation  and EnerTeck



Chemical Corp.,  you are also to turn over all additional  corporate  records in
your  possession,  including  but not  limited  to those  files  which  you have
downloaded  from Debbie  Tenney's  computer on February  9th,  2005 that did not
specifically relate to your job functions at both Companies.  Also included, but
not limited to, those  documents  and  equipment  are the various  passwords and
security  access  codes that are in your  possession  as well as the keys to the
corporate offices in Stafford Texas.

Most Sincerely,

/s/ Parrish B. Ketchmark
