         THIS  AGREEMENT  is made and  entered  into this 17th day of  September
1996, by and between Covol Technologies,  Inc., a Delaware corporation,  and its
predecessor in interest, Environmental Technologies Group International, Inc., a
Nevada  corporation,   Larson  Limestone  Company,   Inc.,  a  Utah  corporation
(collectively  called  "Plaintiffs"),  Michael Q. Midgley,  an individual,  Mark
Hardman, an individual, and Kenneth M. Young, an individual (collectively called
"Messrs.  Midgley  Hardman  and Young,  or  Consolidated  Defendants"),  Farrell
Larson,  an  individual,   Irene  Larson,  an  individual  (collectively  called
"Larsons"),  and  Gary  Burningham  dba  Burningham  and  Company,  a  Financial
Consulting   Firm,  and  Burningham   Enterprises,   Inc.  a  Utah   corporation
(collectively  called  "Burningham").  All  of the  foregoing  Parties  to  this
Agreement  shall be referred to  individually  as a "Party" and  collectively as
"Parties."

                                                     RECITALS

     A.  Plaintiffs  have filed and  maintain a lawsuit  against the Larsons and
Burningham in the Fourth Judicial District Court of Utah County,  State of Utah,
Case  No.   950400278,   entitled   Environmental   Technologies,   Inc.,  Covol
Technologies,  and Larson  Limestone  Company,  Inc. v.  Farrell  Larson,  Irene
Larson,  Gary  Burningham  individually,  and dba  Burningham  and Company,  and
Burningham  Enterprises,  Inc.  asserting  a number of claims.  The  Larsons and
Burningham  have  denied  the  principal  allegations  which  form the basis for
Plaintiffs'  claims,  and  the  Larsons  have  asserted   counterclaims  against
Plaintiffs in this lawsuit.

     B. The  Larsons  filed a lawsuit  against a number of  Plaintiffs'  agents,
their attorneys and their expert in the Fourth  Judicial  District Court of Utah
County,  State of Utah, Case No.  960400032,  entitled  Farrell Larson and Irene
Larson v. Lynn G. Foster, Brett L. Foster, Foster& Foster L.C., Lynn M. Carlson,
Lynn M. Carlson & Co.,  Michael Q.  Midgley,  Mark Hardman and Kenneth M. Young,
asserting a number of claims.  The  Defendants in this case denied the principal
allegations  which formed the basis for the Larsons' claims,  but did not assert
any counterclaims in that lawsuit.

     C. The two  above-referenced  lawsuits were consolidated into a single case
under  Consolidated Case No. 950400278.  These  consolidated cases are hereafter
referred to as the "Litigation."

     D. Lynn G. Foster, Brett L. Foster,  Foster & Foster L.C., Lynn M. Carlson,
and Lynn M. Carlson & Co. moved the Court for summary judgment  dismissal of all
claims the Larsons  asserted  against  them.  The Court has granted that motion,
dismissing all claims against them.  Accordingly,  the only claims still pending
in  the  Larsons'   consolidated   lawsuit  are  against  the   above-referenced
Consolidated Defendants.

     E. Through  this  Agreement,  the Parties  desire to reach a full and final
compromise, settlement, and discharge of all claims, counterclaims, and defenses
which  have  been  asserted  or  which  could  be  asserted  by  Plaintiffs  and
Consolidated  Defendants  against the Larson or Burningham,  and which have been
asserted  or which  could be  asserted  by the  Larsons  or  Burningham  against
Plaintiffs and Consolidated Defendants in the Litigation. This Agreement






is  specifically  intended by the Parties to resolve and forever release any and
all  disputes  or claims  which have been,  may have been,  or could be asserted
between the Parties prior to the date of this Agreement, without reservation.

                                                     AGREEMENT

         Based upon the foregoing, the Parties agree as follows:

         release of said  deposited sums and for  disbursement  of such funds to
         the Larsons.  The Parties  assume and condition  this  Agreement on the
         assumption  that  the  amount  deposited  with  the  Court  is equal to
         $325,000   plus  any   interest   accrued   through  the  date  of  its

         may be other liens or encumbrances  which the Larsons have caused to be
         filed or recorded against Plaintiffs'  equipment,  Plaintiffs are aware

                  shall deliver those executed  U.C.C. 3 Termination  Statements
                  to an agreed  upon escrow  agent which shall  remain in escrow
                  until all loans to which  Farrell  Larson has  guaranteed  are
                  paid off, at which time the escrow  agent shall be  instructed
                  by  Plaintiffs  and the  Larsons  to  deliver  said  U.C.C.  3
                  Termination Statements to Plaintiffs . In respect to all liens
                  and  encumbrances   including  U.C.C.  1  filings   concerning
                  Plaintiffs'  equipment  which are not known but are discovered
                  after the  execution  of this  Agreement,  if any, the Larsons
                  agree to execute an  appropriate,  recordable  release of said
                  liens and  encumbrances,  tender them to an agreed upon escrow
                  agent to hold them  until all loans  that  Farrell  Larson has

                  instructed  who  shall be  instructed  by  Plaintiffs  and the
                  Larsons to deliver  said  release of liens,  encumbrances,  or
