Dear Ken:

Andy Kapusta and I enjoyed  meeting with you and the Covol Team last Tuesday and
we believe this is now a sound  approach to proceed with the Utah Synfuel  Plant
No.  1 and  install  both  extruders  initially  in  Carbon  County.  We are all
optimistic  that Tax Code 29 will be extended -  hopefully  this will allow many
additional  opportunities in 1997 and 1998 for the coal synthetic  agglomeration
facilities.

The  following  documents  our  discussion  with  regard  to  Lockwood  Greene's
investment of its $600,000 fee  associated  with Contract  LG01. The contract as
currently  executed  provides for Covol to pay Lockwood  Greene's  $600,000 fee,
plus cost of all  engineering  and  construction  personnel  and all  associated
expenses.

Lockwood  Greene (LG) is willing to use its $600,000 fee in accordance  with the
following distribution:

1.       LG's fixed fee for Utah Synfuel No. 1 and LG Contract
         LG01-due and payable in cash up front                        $100,000
2.       LG's equity investment in Alabama Synfuel No. 1               400,000
3.       LG's exclusive rights to provide EPCM services for both
         steel mill wastes agglomeration and metallics recovery
         projects and coal fines agglomeration projects                100,000
         Total LG01 Fee                                               $600,000


In addition,  Lockwood Greene/CEC would be reimbursed for all man hours expended
and expenses during the engineering, procurement, and construction phases of the
project in accordance  with  Contract  LG01.  We would  estimate  these costs at
approximately $300,000.

We would like to see additional  details with regard to the equity investment in
Utah's  Synfuel  No. 1. We want to insure  that our equity  investment  will not
expose   Lockwood   Greene  to  any  other   liabilities   with  regard  to  the
operational/financial   aspects   of  Utah   Synfuel   No.  1.  We  would   want
indemnification  from Covol that we would be protected from any financial claims
on the project from Covol and third parties.

If you  are in  agreement  with  the  framework  of this  understanding  and the
attached  Memorandum of  Understanding  between Covol  Technologies and Lockwood
Greene  Engineers,  we would request that you sign two copies of this letter and
the  attached  Memorandum  of  Understanding  and return one signed copy for our
files.  Once  this  document  is  signed,  we will bill the  $100,000  fixed fee
associated with Contract LG01 and we would expect receipt of this payment within
thirty days after invoicing.

Again, we appreciate the opportunity of working with Covol in the development of
these coal agglomeration  projects and we further look forward to developing the
steel mill waste stream agglomeration and metallics recovery projects.

Very truly yours,

LOCKWOOD GREENE ENGINEERS, INC.
