The Huck International, Inc. Excess Benefit Plan for Selected Employees has
been  established  to  supplement  the  retirement  benefits of certain key

Retirement  Account Plan ("PRA"),  a  tax-qualified  retirement  plan under
Section  401(a)  of the  Internal  Revenue  Code of 1986,  as  amended,  by
expanding the compensation on which benefits are calculated, by providing a
higher  contribution  rate than the PRA,  and by  providing  benefits  that
cannot be paid by the PRA on account of limitations in the Internal Revenue
Code.

SECTION 5 - BENEFITS

5.1  Benefits formula

     A separate unfunded book account is maintained for each Participant. A
     Participant's   accrued  benefit  under  the  Plan  is  equal  to  the
     Participant's  account balance.  A Participant's  account balance will
     equal the sum of the amounts in subsections  (i), (ii), and (iii), and
     reduced by the amount in subsection (iv).

     (i)  As of the  Effective  Date,  an amount  shall be  credited to the
          Participant's  account equal to the accrued  benefit,  if any, of
          the  Participant  in the Prior Plan plus  interest for the period
          from November 1, 1991 to the Effective  Date at the rate that was
          in effect under the Prior Plan on November 1, 1991.

     (ii) As of the last day of each calendar month of active Participation
          under the PRA,  the  following  amount  shall be  credited to the
          Participant's account:

                                     4

<PAGE>


          (a) 2-1/2 percent of Plan Compensation  received by the Participant
          for each such calendar  month which ends prior to his  attainment
          of age 30;

          (b) 3-3/4 percent of Plan Compensation  received by the Participant
          for each such calendar  month which ends prior to his  attainment
          of age 40 but subsequent to his attainment of age 30;

          (c) 5 percent of Plan  Compensation  received by the  Participant
          for each such calendar  month which ends prior to his  attainment
          of age 50 but subsequent to his attainment of age 40;

          (d) 7-1/2 percent of Plan Compensation  received by the Participant
          for each such calendar  month which ends prior to his  attainment
          of age 60 but subsequent to his attainment of age 50; and

          (e) 10 percent of Plan  Compensation  received by the Participant
          for each such calendar month  subsequent to his attainment of age
          60.

     (iii)Until  January  1, 1997 a  Participant's  account  balance  shall
          receive a credit as of the last day of each calendar  month equal
          to the product of (1) the interest rate used by the PBGC to value
          lump sum  benefits for plans  terminating  as of the first day of
          the Plan Year, compounded monthly at a simple annual rate and (2)
          the  Participant's  account  balance  as of the  last  day of the
          calendar  month.  After January 1, 1997 a  Participant's  account
          balance  shall  receive  a  credit  as of the  last  day of  each
          calendar  month  equal to the  product  of the  average  yield on
          1-year Treasury Constant Maturities for November of the preceding
          Plan Year plus 100 basis points and (2) the Participant's account
          balance as of the last day of the calendar month.

     (iv) A  Participant's  account balance shall be reduced by the account
          balance  payable  under the PRA (after  taking  into  account the
          limitations imposed by Code Section 415).


5.2      Vesting and Forfeiture

          The vested percentage of a Participant's  benefit under this Plan
          shall be  equal to the  vested  percentage  of the  Participant's
          accrued  benefit  under the PRA;  however,  a  Participant  shall
          forfeit all benefits under the Plan if --

          (i)  the Participant engages in a willful,  deliberate,  or gross
               act of  commission  or omission  which is  injurious  to the
               finances  or  reputation  of  the  Employer  or  any  of its
               affiliates;

                                     5

<PAGE>


          (ii) prior  to age 65,  the  Participant  serves  as a  director,
               officer,   partner,   employee,    consultant,   agent,   or
               representative  of  any  business  entity  which  sells  any
               product or service in direct competition with any product or
               service sold by the Employer or any affiliate; or

          (iii) the Participant breaches any agreement with the Employer.

          In the event a Participant voluntarily terminates employment with
          the Employer,  any benefits under this plan,  unless vested under
          the  vesting  provisions  of this  Plan at the time the  Employee
          terminates, shall be forfeited, and the Participant shall receive
          no benefits.

5.4      Payment of Benefits

          A Participant's entire account balance will be distributed in the
          form of a lump sum payment at the same time a Participant  elects
          under the  terms of the PRA to  receive  the  first  PRA  benefit
          payment.  In no event shall a benefit be payable to a Participant
          in a month the Participant  receives Plan  Compensation  from the
          Employer.

SECTION 6 - DEATH

If a married  Participant dies before his account balance is distributed to
him, his account  balance shall be 100% vested on the date of his death and
the entire account  balance shall be payable to his spouse at the same time
the  spouse  elects  under  the terms of the PRA to  receive  the first PRA
benefit  payment.  If an  unmarried  Participant  dies  before his  annuity
starting date,  the vested portion of his account  balance shall be paid to
his estate or beneficiary, as appropriate.

SECTION 7 - INCOME TAX WITHHOLDING

The Employer  shall deduct from all payments  under this Plan the amount of
any applicable income and employment tax withholding requirements.

SECTION 8 - NO REQUIREMENT TO FUND

The entire cost of providing  benefits  under the Plan shall be paid by the
Employer  out of its current  operations,  and the  Employer's  obligations
under the Plan shall be an  unfunded  and  unsecured  promise  to pay.  The
Employer  shall  not be  obligated  under  any  circumstances  to fund  its
obligations  under the Plan. No  contributions by Participants are required
or permitted under the Plan.

                                     6

SECTION 9 - ADMINISTRATION

The Plan shall be administered  by the Committee.  The Committee shall have
plenary  authority,  subject to the express  provisions  hereof,  to select
Employees  eligible  to  participate  in the Plan;  resolve  any  questions
arising  under the Plan;  to correct  any defect or supply an  omission  or
reconcile any  inconsistency;  to establish amend and rescind any rules and
regulations  relating  to the  Plan and to make  all  other  determinations
necessary or advisable  for the  administration  and  continued  successful
operation of the Plan. Any decision of the Committee in the  administration
of the  Plan,  as  described  herein,  shall be final and  conclusive.  The
Committee  shall act only by a majority of its  members  then in office and
its actions  shall be recorded in minutes of the Committee  meetings  which
shall be conclusive of all such actions taken. The Committee shall have the
right to delegate  such Plan  administration  as it shall  determine to the
Chairman or Chairman's designee.

SECTION 10 - LIMITATION OF PARTICIPANT'S RIGHTS

10.1      Plan not a Contract of Employment

          Neither this Plan, nor participation in it, shall be construed in
          any  manner  as a  contract  of  continuing  employment  with the
          Corporation  either  expressed  or  implied.  Nothing in the Plan
          shall  interfere  with  or  limit  in any way  the  right  of the
          Corporation  to terminate  any  Participant's  employment  at any
          time, or confer upon any Participant any right to continue in the
          employ of the Corporation for any period of time or to continue a
          Participant's  present  or any  other  rate of  compensation.  No
          employee shall have a right to be selected as a  Participant,  or
          having been so selected, to be selected again as a Participant.

10.2     Unsecured Creditor

          The rights of any Participant or any person claiming  through the
          Participant  under the Plan shall be solely those of an unsecured
          general creditor of the Employer. Any Participant,  or any person
          claiming  through the  Participant,  shall only have the right to
          receive  from the  Employer  those  payments as specified in this
          Plan.  Each  Participant  agrees  that he or any person  claiming
          through  him shall have no rights or  interests  in any assets of
          the Employer.

10.3     No Trust

          No asset used or acquired by the Employer in connection  with the
          liabilities  it has assumed  under the Plan shall be deemed to be
          held  under any trust for the  benefit  of any  Participant.  Nor
          shall any such asset be considered  security for the  performance
          of the obligations of the Employer,  but shall be, and remain,  a
          general unpledged and unrestricted asset of the Employer,  except
          as provided by separate agreement and as permitted under Internal
          Revenue Service and

                                     7

<PAGE>

          Department   of  Labor  rules  and   regulations   for   unfunded
          supplemental retirement plans.

10.4     Plan Binding

          The  Plan  is  binding  on  the  beneficiaries,   executor,   and
          administrator  of the  Participant,  and upon the  successors (by
          sale or  otherwise)  of the Company who succeed to  substantially
          all the assets and the business of the Company.

SECTION 11 - AMENDMENT OR TERMINATION

Subject to the provisions of this Section 11, the Committee  shall have the
right at any  time,  from  time-to-time,  with  notice to  Participants  to
suspend,  discontinue or amend this Plan in any respect whatsoever. No such
amendment or  termination  shall  reduce or  otherwise  affect the benefits
payable to or on behalf of any Participant  that have accrued prior to such
amendment or termination without the written consent of the Participant (or
beneficiary,   if  applicable).   In  addition,  the  complete  or  partial
termination  of this Plan  shall  have the same  effect on the  vesting  of
benefits  accrued to date  under this Plan as in the case of a complete  or
partial termination of the PRA.

SECTION 12 - SPENDTHRIFT CLAUSE

No right,  title or interest of any kind in the Plan shall be  transferable
or  assignable  by any  Participant  or  Surviving  Spouse or be subject to
alienation, anticipation,  encumbrance,  garnishment, attachment, execution
or levy of any kind,  whether voluntary or involuntary,  nor subject to the
debts, contracts, liabilities,  engagements, or torts of the Participant or
Surviving  Spouse.  Any attempt to alienate,  anticipate,  encumber,  sell,
transfer,  assign, pledge, garnish, attach or otherwise subject to legal or
equitable  process or encumber or dispose of any interest in the Plan shall
be void.

SECTION 13 - PAYMENT DUE AN INCOMPETENT

If the Plan  Administration  Committee receives evidence that a Participant
or  Surviving  Spouse  entitled to receive  any  payment  under the Plan is
physically or mentally  incompetent to receive such payment,  the Committee
may,  in its sole  discretion,  direct the  payment to any other  person or
trust which has been legally appointed by the courts.

SECTION 14 - CONSTRUCTION

Whenever  appropriate,  words used in the singular shall include the plural
or the plural may be read as the singular.  When used herein, the masculine
gender includes the feminine gender.


                                     8

SECTION 15 - SEVERABILITY

In the event that any  provision of this Plan shall be declared  illegal or
invalid for any reason,  said illegality or invalidity shall not affect the
remaining  provisions  of this Plan but shall be fully  severable  and this
Plan  shall  be  construed  and  enforced  as if said  illegal  or  invalid
provision had never been inserted herein.

SECTION 16 - GOVERNING LAW

The validity and effect of this Plan and the rights and  obligations of all
persons  affected  hereby shall be construed  and  determined in accordance
with the laws of the State of Utah unless superseded by federal law.

IN WITNESS  WHEREOF,  the Board of  Directors  has  caused  this Plan to be
signed by its duly appointed officers and its corporate seal to be hereunto
affixed as of this 16th day of June, 1997.
