     sponsoring employer and such corporation agrees to be bound by the terms of
     this Plan.

          (e)  "Compensation" shall mean the total compensation paid by the
     Company to an Employee for services rendered for the period under
     consideration (other than compensation in the form of qualified or

     income of the Employee for income tax purposes.  Effective January 1, 1992,
     "Compensation" shall also include amounts that are not includible in income
     of the Employee under Code Section 125 (except for amounts not includible
     in income under Code Section 125 which are applied to the payment of
     medical insurance premiums on behalf of such Employee).  No more than
     $200,000 (or such higher amount as determined by the Secretary of the
     Treasury pursuant to Section 416(d)(2) of the Code) of Compensation shall
     be taken into account for all purposes of this Plan.

          (f)  "Disability" shall mean a physical or mental condition of a
     Participant resulting from bodily injury, disease or mental disorder which
     renders him incapable of continuing any gainful occupation and which
     condition constitutes total disability under a medically determinable

          (g)  "Employee" shall mean any person employed by the Company or any
     other employer required to be aggregated with the Company under Sections
     414(b), (c), (m), or (o) of the Code, but excluding any member of a
     collective bargaining unit with which the Company is required to negotiate
     with respect to retirement benefits (if retirement benefits have been the
     subject of good faith negotiation).  After January 1, 1991, the term
     "Employee" shall exclude any person who is employed on an hourly basis.

          Employee shall also include any Leased Employee deemed to be an
     Employee as provided in Sections 414(n) or (o) of the Code.

                                      -2-

 
          (i)  "Fund" or Funds" shall mean the investment fund or funds
     established and maintained hereunder by the Trustee for the Plan pursuant
     to subparagraph 8. A.
                     -- --

          (j)  "Gross Compensation" shall mean a Participant's Compensation
     (including all amounts not includible in income of the Participant under
     Code Section 125) plus amounts deferred hereunder pursuant to a salary
     reduction agreement.

          (k)  "Highly Compensated Employee" shall include highly compensated
     active and former employees.  A highly compensated active employee is any
     Employee who performs service for the Employer during the determination
     year and who, during the determination year:  (i) received Compensation
     from the Employer in excess of $75,000 (as adjusted pursuant to Section
     415(d) of the Code); (ii) received Compensation from the Employer in excess
     of $50,000 (as adjusted pursuant to Section 415(d) of the Code) and was a
     member of the top-paid group for such year; (iii) was an officer of the
     Employer and received Compensation during such year that is greater than 50
     percent of the dollar limitation in effect under Section 415(b)(1)(A) of
     the Code; or (iv) was a 5 percent owner at any time during the
     determination year.

          If no officer has satisfied the Compensation requirement of (iii)
     above, during a determination year, the highest paid officer for such year
     shall be treated as a Highly Compensated Employee.

          For this purpose, the determination year shall be the Plan Year, and
     the Employer elects the calendar year calculation election as provided in
     Treasury Regulation (S) 1.414(q)-IT, A-14(b).

          A highly compensated former employee is any Employee who separated
     from service (or was deemed to have separated) prior to the determination
     year, performs no service for the Employer during the determination year,
     and was a highly compensated active employee for either the separation year
     or any determination year ending on or after the Employee's 55th birthday.

          If an Employee is, during a determination year, a Family member of
     either a 5 percent owner who is an active or former employee or a Highly
     Compensated Employee who is one of the 10 most highly compensated employees
     ranked on the basis of compensation paid by the Employer during such year,
     then the Family member and the 5 percent owner or top-ten Highly
     Compensated Employee shall be aggregated.  In such case, the Family member
     and 5 percent owner or top-ten Highly Compensated Employee shall be treated
     as a single employee receiving compensation and plan contributions or
     benefits equal to the sum of such compensation and contributions or
     benefits of the Family member and 5 percent owner or top-ten Highly
     Compensated Employee.

                                      -3-

 
          The determination of who is a Highly Compensated Employee, including
     the determinations of the number and identity of Employees in the top-paid
     group, the number of Employees treated as officers and the Compensation
     that is considered, will be made in accordance with Section 414(q) of the
     Code and the regulations thereunder.

          (l)  "Hour of Service" shall mean each hour for which an Employee is
     directly or indirectly paid, or entitled to payment, by the Company for the
     performance of duties (such hours to be credited for the computation period
     in which the duties were performed), each hour for which back pay,
     irrespective of mitigation of damages, has been either awarded or agreed to
     by the Company (such hours to be credited for the computation period to
     which the award or agreement pertains), and each hour for which an Employee
     is directly or indirectly paid, or entitled to payment, by the Company for
     reasons (such as vacation, sickness, disability, holidays, paid layoff and
     similar paid periods of nonworking time) other than the performance of
     duties (such hours to be credited for the computation period in which such
     period of nonworking time first occurs).

          With respect to an Employee who is absent from work for any period (i)
     by reason of the pregnancy of the Employee; (ii) by reason of the birth of
     a child of the Employee; (iii) by reason of the placement of a child with
     the Employee in connection with the adoption of such child by such
     Employee, or (iv) for purposes of caring for such child for a period
     beginning immediately following such birth or placement, then solely for
     purposes of determining whether a One-Year Break in Service has occurred,
     such Employee shall be credited with the Hours of Service which otherwise
     would have been credited to such Employee but for such absence.  In the
     event that the Plan Administrator is unable to determine the Hours of
     Service with respect to such absence, the Employee shall be credited with
     eight Hours of Service for each normal workday of such absence.  No credit
     for Hours of Service shall be granted with respect to an absence described
     in this paragraph if the Employee fails to timely provide information
     required by the Plan Administrator which is reasonably required to
     establish that the Employee was absent from work for a reason described in
     this paragraph and to establish the number of days for which there was such
     an absence.  Hours of Service which are credited pursuant to this paragraph
     shall be credited only in the Plan Year in which the absence from work
     begins (if the Employee would be prevented from incurring a One-Year Break
     in Service in such year solely because the Employee is credited with Hours
     of Service pursuant to this paragraph), or in any other case, in the
     immediately following Plan Year.

          No more than 501 Hours of Service shall be credited to an Employee on
     account of any single continuous period during which the Employee performs
     no duties.  In addition to the foregoing, the rules set forth at Sections
     2530.200b-2(b) and 2(c) of the Department of Labor Regulations shall apply
     in determining Hours of Service.

                                      -4-

 
          An Hour of Service respecting any member of a controlled group of
     corporations or any member of an affiliated service group (as defined in
     Section 414(b), 414(m) or 414(o) of the Code) of which the Company is a
     member, or respecting an unincorporated trade or business which is under
     common control with the Company (as defined in Section 414(c) of the Code)
     or any other entity required to be aggregated with the Company under
     Section 414(o) of the Code shall be credited as an Hour of Service with the
     Company.

          (m)  "Income" shall mean the income allocable to "excess
     contributions" or "excess aggregate contributions" within the meaning of
     subparagraphs 7. C. or 7. D., below for the Plan Year in which such excess
                   -- --    -- --
     contribution was made. The amount of income attributable to such excess
     contributions shall be determined by the Administrator in a reasonable and
     consistent manner. Income shall not include income allocable to excess
     contributions for the Plan Year in which the excess contribution is
     returned to the Participant.

          (n)  "Non-Highly Compensated Employee" shall mean an Employee who is
     neither a Highly Compensated Employee nor a member of his Family.

          (o)  "Normal Retirement Age" shall mean age sixty-five (65).

          (p)  "One-Year Break in Service" shall mean a Plan Year during which
     an Employee does not complete more than one Hour of Service with the
     Company. For purposes of determining eligibility to participate in the
     Plan, such 12-month period shall be calculated with reference to the
     Employee's "Employment Commencement Date" (as defined in subparagraph 2.(w)
                                                                           -
     below), and annual anniversaries thereof. For purposes of determining the
     nonforfeitable percentage of a Participating Employee's share in the Trust,
     such 12-month period shall be deemed to be the Plan Year.

          (q)  "Participating Employee" and "Participant" shall mean any
     Employee of the Company who is eligible to participate in Company
     contributions to the Plan and Trust. "Beneficiary" shall mean a person who
     has become eligible to participate and for whom an account is maintained by
     the Trustee, but who has ceased to be an Employee of the Company, or a
     person entitled to benefits hereunder as beneficiary of a deceased
     Participating Employee or as beneficiary of a deceased Beneficiary.

          (r)  "Plan" shall mean the Advanstar Communications Inc. Employees'
     401(k) Plan set forth in and by this Agreement and all subsequent
     amendments thereto.

          (s)  "Plan Year" shall mean the calendar year.

                                      -5-

 
          (t)  "Revaluation Date"  shall mean the last day of a Plan Year, or
     such other additional dates as are mutually agreeable to the Trustee and
     the Company.

          (u)  "Trust" shall mean the Advanstar Communications Inc. Employees'
     401(k) Trust set forth herein.

          (v)  "Trustee" shall mean the Trustee or Trustees appointed from time
     to time by the Company to accept contributions, administer the assets of
     the Trust, and otherwise to act in accordance with this Plan and Trust.

          (w)  "Vesting Year of Service" shall mean a period of twelve (12)
     consecutive months during which a Participating Employee completes at least
     one (1) Hour of Service.  Such 12-month period shall be calculated with
     reference to the Employee's "Employment Commencement Date" (the first date
     of employment on which the Employee is credited with an Hour of Service
     with the Company), and subsequent such 12-month periods shall be calculated
     with reference to subsequent anniversaries of said Employment Commencement
     Date.  In determining Vesting Years of Service, service with Harcourt Brace
     Jovanovich, Inc. shall be considered as service with the Company.

          An Employee who ceases to be a Participant, but who remains in the
     employment of the Company, shall continue to be credited with Vesting Years
     of Service under this Plan so long as he remains in the employment of the
     Company.  An Employee who was in the employment of the Company before he
     became an Employee for purposes of this Plan shall receive credit for
     Vesting Years of Service as though he had been an Employee during such
     prior period of employment with the Company.

          (x)  "Year of Service" shall mean a period of twelve (12) consecutive
     months during which an Employee has not less than 1,000 Hours of Service
     with the Company.  Such 12-month period shall be calculated with reference
     to the Employee's "Employment Commencement Date" (the first date of
     employment on which the Employee is credited with an Hour of Service with
     the Company), and subsequent such 12-month periods shall be calculated with
     reference to subsequent anniversaries of said Employment Commencement Date.

     Where necessary or appropriate to the meaning hereof, the singular shall be
deemed to include the plural, the plural to include the singular, the masculine
to include the feminine and neuter, the feminine to include the masculine and
neuter, and the neuter to include the masculine and feminine.

     3.   Purpose.
     --   ------- 

                                      -6-

 
     This Trust was created and continues in existence for the purpose of
enabling eligible Employees of the Company to defer a portion of their
compensation until retirement and to share in the profits of the Company's
business.  Except as provided in Paragraph 32. below, in no event shall any part
                                           ---                                  
of the principal or income of this Trust be paid to or revested in the Company,
or be used for any purpose whatsoever other than the exclusive benefit of such
Employees and their Beneficiaries.

     All discretionary acts taken by the Trustee hereunder shall be uniform in
their nature and application to all persons similarly situated, and no
discretionary acts shall be taken which shall be discriminatory under the
provisions of the Code or the Employee Retirement Income Security Act of 1974,
as they relate to employees' profit-sharing trusts, as such provisions now exist
or may from time to time be amended.

     4.   Plan Entry Requirements.
     --   ----------------------- 

     Each Employee of the Company shall enter the Plan on the first day of the
calendar month next following the later to occur of the end of the 12-month
period of service which constitutes a Year of Service with respect to such
Employee and his attainment of age twenty-one (21).  Prior to January 1,  1991,
each Employee of the Company shall enter the Plan on the January 1 or July 1
next following the later to occur of the end of the 12-month period of service
which constitutes a Year of Service with respect to such Employee and his
attainment of age twenty-one (21).  An Employee who has met the Plan entry
requirements may elect not to participate in the Plan by providing the Company
with written notice of his or her election not to be included as a Participant.
Said election shall remain in effect until the Employee provides the Company
with written notice of his or her election to become a Participant.

     With respect to an Employee who has met the eligibility requirements of the
Plan but who has incurred a One-Year Break in Service, such Employee shall be
eligible to re-enter the Plan commencing immediately upon his return.  In the
event an Employee who is not a member of an eligible class of employees becomes
a member of an eligible class, such employee will participate immediately if
such Employee has satisfied the minimum age and service requirements and would
have otherwise previously become a Participant.  In the event that the
eligibility of any person to participate in the Plan shall be disputed, the
decision of the Trustee upon such eligibility shall be controlling.  For the
purposes of enabling the Trustee to make such determination, all information
available to the Company which shall be required by the Trustee shall be made
available to the Trustee.

     5.   Contributions.
     --   ------------- 

     Subject to the provisions of subparagraphs 8. H. and 8. I. below,
                                                -- --     -- --       
contributions under the 

                                      -7-

 
Plan shall be made as follows:

          A.   Salary Reduction Contributions.  Each Participant may elect to
          --   ------------------------------                                
     enter into a salary reduction agreement with the Company under which the
     Participant agrees to accept a reduction in salary from the Company (such
     reduction not to exceed fifteen percent (15%) of such Participant's Gross
     Compensation with respect to any Plan Year).  Said salary reduction
     agreement shall be filed by the Participant with the Company within 30 days
     prior to the payment of Compensation to which such salary reduction
     agreement applies.  In consideration of such agreement, the Company will
     make a salary reduction contribution to the Participant's Salary Reduction
     Contribution Account on behalf of the Participant for such Plan Year in an
     amount equal to the total amount by which the Participant's Compensation
     from the Company was reduced during the Plan Year pursuant to the salary
     reduction agreement.  Contributions made by the Company for a given Plan
     Year pursuant to salary reduction agreements shall be deposited with the
     Trustee within a reasonable amount of time, but in no event will such
     deposit be made more than 90 days following the date such funds are
     withheld from the Participant's salary.

          Salary reduction contributions made pursuant to this subparagraph A.
                                                                            --
     shall be governed by the following additional provisions:

               (1)  Amounts credited to a Participant's Salary Reduction Account
          shall be 100 percent vested and nonforfeitable at all times.

               (2)  Amounts credited to a Participant's Salary Reduction Account
          shall be considered as a contribution made by the Company for purposes
          of subparagraphs 8. H., 8. I. and 26. B.
                           -- --  -- --     --- --

               (3)  A salary reduction agreement may provide for a reduction in
          salary by means of reducing the Participant's payroll on a periodic
          basis, or the agreement may provide for lump sum reductions with
          respect to any compensation payments in such amounts that will not
          cause the limitations of Paragraphs 7., 8. H., or 8. I. to be
                                              --  -- --     -- --      
          exceeded.

               (4)  A salary reduction agreement providing for reductions to a
          Participant's periodic payroll may be cancelled at any time by a
          Participant by giving at least 30 days advance written notice to the
          Company, specifying the effective date of the cancellation.  A
          Participant may change the rate of his salary reduction four (4) times
          per Plan Year, to be effective as of any January 1, April 1, July 1,
          or October 1 following such election, by filing an amended salary
          reduction agreement with the Company within thirty (30) days prior to
          said date.

                                      -8-

 
               (5)  The Company may refrain from making contributions to this
          Plan, in respect of the salary reduction agreement entered into by the
          Participant, if the Company determines that such action is necessary
          to insure that the Participant's annual additions for any Plan Year
          will not exceed the limitations of subparagraphs 8. H. or 8. I.
                                                           -- --    -- --
          hereinbelow, or to insure that the Actual Deferral Percentage Test
          described in Paragraph 7. hereinbelow is met for such Plan Year.  In
                                 --                                           
          any such event, the Company may pay to the Participant the amount
          which otherwise would have been paid prior to the Participant's
          election to reduce his salary, rather than as a contribution made
          pursuant to a salary reduction agreement.

               (6)  A salary reduction agreement shall not provide for a
          reduction in excess of $7,000 (or such higher amount as determined by
          the Secretary pursuant to Section 415(d) of the Code) under all plans
          maintained by the Company with respect to any Employee's taxable year.

          B.   Matching Company Contributions.  Not later than the time
          --   ------------------------------                          
     prescribed by law for filing its federal income tax return (including any
     extensions thereof) for its current taxable year, the Company shall
     contribute to the Trustee, on behalf of each Participant, as its Matching
     Company Contribution to the Trust for the Plan Year which ends within or
     which is co-terminous with such taxable year of the Company, to be held in
     trust, administered and distributed under the terms of this Agreement, an
     amount to be determined as follows:

               (1)  With respect to Salary Reduction Contributions up to the
          first two percent (2%) of the Participant's Gross Compensation, the
          Matching Company Contribution shall be equal to 100% of the Salary
          Reduction Contribution;

               (2)  With respect to Salary Reduction Contributions in excess of
          two percent (2%) of the Participant's Gross Compensation and not in
          excess of six percent (6%) of the Participant's Gross Compensation,
          the Matching Company Contribution shall be equal to 25% of such Salary
          Reduction Contribution; and

               (3)  With respect to Salary Reduction Contributions in excess of
          six percent (6%) of the Participant's Gross Compensation, there shall
          be no Matching Company Contribution.  In no event shall the Matching
          Company Contribution made on behalf of a Participant in a Plan Year
          exceed three percent (3%) of the Participant's Gross Compensation.

          In determining the Matching Company Contribution, the computation of
     the Salary Reduction Contribution as a percentage of Gross Compensation
     shall be made on a per payroll basis.

                                      -9-

 
          Notwithstanding the foregoing, the Company shall not contribute to the
     Plan as a Matching Company Contribution any amount that would cause the
     limitation set forth in Paragraph 7. to be exceeded, considering only
                                       --                                 
     Matching Company Contributions, rather than Salary Reduction Contributions.

          C.   Discretionary Company Contributions.  Not later than the time
          --   -----------------------------------                          
     prescribed by law for filing its federal income tax return (including
     extensions thereof) for its current taxable year and for each succeeding
     taxable year, the Company may contribute to the Trust fund, as its
     contribution to this Trust for the Plan Year which ends within or which is
     co-terminous with such taxable year of the Company, to be held in trust,
     administered and distributed under the terms of this Agreement, an amount
     or amounts which the Company, in its sole discretion may determine.  The
     Company may contribute such amount or amounts at any time; and it may make
     such contribution in two or more installments.

          The Company shall determine by resolution of its Board of Directors
     and communicate to the Trustee before the close of each Plan Year either
     (i) the amount in dollars to be contributed for such year, or (ii) a
     formula by which such amount may be determined.  These contributions shall
     be totally in the discretion of the Company with respect to amount, timing
     and form, and they need not be limited to the profits of the Company.  The
     Company may make such contributions in cash or in kind.  Nothing in this
     Agreement shall entitle any Trustee, Participating Employee or Beneficiary
     to inquire into or demand the right to inspect the books or records of the
     Company.

          D.   Rollover Contributions.  An Employee, whether or not he would
          --   ----------------------                                       
     otherwise be a Participant in the Plan, may contribute a "Rollover
     Contribution" to the Trust by delivery of such contribution to the Trustee;
     provided that such Employee submits a written certification that such
     contribution qualified as a Rollover Contribution as defined hereinbelow.

          For purposes of this subparagraph D., for an amount to qualify for
                                            --                              
     contribution by an Employee as a Rollover Contribution, it must:

               (1)  represent the balance to the credit of such Employee under a
          plan qualified under Section 401 of the Code, and have been paid to
          him:

                    (a)  within one taxable year of the Employee on account of
               the termination of such plan, or if such plan was a profit-
               sharing or stock bonus plan, upon complete discontinuance of
               Employer contributions thereto, or

                    (b)  in one or more distributions which constitute a lump 
               sum

                                     -10-

 
               distribution; or

               (2)  represent the balance to his credit of a conduit Individual
          Retirement Account or similar account or annuity, unless such balance
          is derived in any part from a previous rollover of a partial qualified
          plan contribution; and (in either the case of compliance with
          subdivision (1) above or this subdivision (2)); and

               (3)  be contributed to the Plan within 60 days following
          distribution of such amount to the Employee.

          In addition to the foregoing, the provisions of Code Sections
     402(a)(6)(C), (D) and 402(a)(7) shall apply in determining the
     permissibility of a desired Rollover Contribution by an Employee.

          An amount will not qualify as a Rollover Contribution if it includes
     any amount which constituted a contribution made by the Employee to a plan
     qualified under Section 401 of the Code.

          A Rollover Contribution shall be considered as a part of the account
     of the contributing Employee in this Plan, shall be fully vested and
     nonforfeitable, and shall be accounted for separately from Company
     contributions.

          A Participant may also arrange for the direct transfer of his benefit
     from a plan qualified under Section 401 of the Code to this Plan.  For
     accounting and record keeping purposes, transfer contributions shall be
     identical to Rollover Contributions.

          If a Rollover Contribution is from a plan that is subject to the
     provisions of Code Section 417, with respect to qualified joint and
     survivor annuities and qualified preretirement survivor annuities, the
     rules of said Section 417 shall continue to apply to the Participant's
     Rollover Contribution Account.

     6.   Withdrawals.
     --   ----------- 

          A.   Age 59-1/2.  A Participant who has attained age 59-1/2 may
          --   ----------                                                
     withdraw all or any portion of his Salary Reduction Account by notifying
     the Trustee of his election to make such a withdrawal.

          B.   Hardship.  In the event a Participant who has not attained age 59
          --   --------                                                         
     1/2 suffers a serious financial hardship, such Participant may withdraw a
     portion of his account attributable to his Salary Reduction Contributions
     (but not the earnings on such 

                                     -11-

 
     contributions) as provided hereinbelow. The determination of whether a
     serious financial hardship exists shall be based on all relevant facts and
     circumstances. A need shall not be disqualified because it was reasonably
     foreseeable or voluntarily incurred. Withdrawal under this subparagraph 6.
                                                                             --
     B. shall be authorized only if the distribution is on account of:
     --

               (1)  Medical expenses described in Code Section 213(d) incurred
          by the Participant, his spouse, or any of his dependents (as defined
          in Code Section 152);

               (2)  The purchase (excluding mortgage payments) of a principal
          residence for the Participant;

               (3)  Payment of tuition for the next semester or quarter of post-
          secondary education for the Participant, his spouse, children, or
          dependents; or

               (4)  The need to prevent the eviction of the Participant from his
          principal residence or foreclosure on the mortgage of the
          Participant's principal residence.

          C.   Conditions for Hardship Distribution.  No distribution shall be
          --   ------------------------------------                           
     made pursuant to Paragraph 6. B. above unless the Administrator, based upon
                                -- --                                           
     the Participant's representation and such other facts as are known to the
     Administrator, determines that the following conditions are satisfied:

               (1)  The distribution is not in excess of the amount of the
          immediate and heavy financial need of the Participant; and

               (2)  The Participant has obtained all distributions, other than
          hardship distributions, and all nontaxable loans currently available
          under all plans maintained by the Employer.

          D.   Available Other Resources.  No distribution shall be made
          --   -------------------------
     pursuant to subparagraph 6. B. unless the Administrator determines, based
                              -- -
     upon all relevant facts and circumstances, that the amount to be
     distributed is not in excess of the amount required to relieve the
     financial need and that such need cannot be satisfied from other resources
     reasonably available to the Participant. For this purpose, the
     Participant's resources shall be deemed to include those assets of his
     spouse and minor children that are reasonably available to the Participant.
     A distribution may be treated as necessary to satisfy a financial need if
     the Administrator relies upon the Participant's representation that the
     need cannot be relieved:

                                     -12-

 
               (1)  Through reimbursement or compensation by insurance or
          otherwise;

               (2)  By reasonable liquidation of the Participant's assets, to
          the extent such liquidation would not itself cause an immediate and
          heavy financial need;

               (3)  By cessation of Salary Reduction Contributions and voluntary
          Employee contributions, if available, under the Plan; or

               (4)  By other distributions or loans from the Plan, if available,
          or any other qualified retirement plan, or by borrowing from
          commercial sources on reasonable commercial terms.

     7.   Special Nondiscrimination Testing.
     --   --------------------------------- 

          A.   Actual Deferral Percentage Tests.  For each Plan Year the Plan
          --   --------------------------------                              
     shall satisfy one of the following tests:

               (1)  The "Actual Deferral Percentage" for the Highly Compensated
          Employee group shall not be more than the "Actual Deferral Percentage"
          of the Non-Highly Compensated Employee group multiplied by 1.25, or

               (2)  The excess of the "Actual Deferral Percentage" for the
          Highly Compensated Employee group over the "Actual Deferral
          Percentage" for the Non-Highly Compensated Employee group shall not be
          more than two percentage points. Additionally, the "Actual Deferral
          Percentage" for the Highly Compensated Employee group shall not exceed
          the "Actual Deferral Percentage" for the Non-Highly Compensated
          Employee group multiplied by 2. The provisions of Code Section
          401(k)(3) and Regulation 1.401(k)-1(b) are incorporated herein by
          reference.

          For the purposes of this Paragraph 7. "Actual Deferral Percentage"
                                             --                             
     means, with respect to the Highly Compensated Employee group and Non-Highly
     Compensated Employee group for a Plan Year, the average of the ratios,
     calculated separately for each Participant in such group, of the amount of
     Salary Reduction Contributions allocated to each Participant's Salary
     Reduction Contribution Account for such Plan Year to such Participant's
     Compensation for such Plan Year. The actual deferral ratio for each
     Participant and the "Actual Deferral Percentage" for each group shall be
     calculated to the nearest one-hundredth of one percent.

          For the purpose of determining the actual deferral ratio of a Highly
     Compensated 

                                     -13-

 
     Employee who is subject to the Family Member aggregation rules of Code
     Section 414(q)(6) because such Participant is either a "five percent owner"
     of the Employer or one of the ten (10) Highly Compensated Employees paid
     the greatest "415 Compensation" during this year, the following shall
     apply:

               (1)  The combined actual deferral ratio for the family group
          (which shall be treated as one Highly Compensated Employee) shall be
          the greater of (i) the ratio determined by aggregating Salary
          Reduction Contributions and Gross Compensation of all eligible Family
          Members who are Highly Compensated Employees without regard to family
          aggregation; and (ii) the ratio determined by aggregating Employees
          Contributions and Gross Compensation of all eligible Family Members
          (including Highly Compensated Employees).

               (2)  The Salary Reduction Contributions and Gross Compensation of
          all Family Members shall be disregarded for purposes of determining
          the "Actual Deferral Percentage" of the Non-Highly Compensated
          Employee group except to the extent taken into account in paragraph
          (1) above.

               (3)  If a Participant is required to be aggregated as a member of
          more than one family group in a plan, all Participants who are members
          of those family groups that include the Participant are aggregated as
          one family group in accordance with paragraphs (1) and (2) above.

          For the purposes of this subparagraph 7. A., a Highly Compensated
                                                -- --                      
     Employee and a Non-Highly Compensated Employee shall include any Employee
     eligible to make a Salary Reduction Contribution pursuant to subparagraph
     5. A., whether or not such deferral election was made or suspended pursuant
     -- --                                                                      
     to subparagraph 5. A.
                     -- --

          For the purposes of this subparagraph 7. A. and Code Sections
                                                -- --                  
     401(a)(4), 410(b) and 401(k), if two or more plans which include cash or
     deferred arrangements are considered one plan for the purposes of Code
     Section 410(a)(4) or 410(b) (other than Code Section 410(b)(2)(A)(ii)), the
     cash or deferred arrangements included in such plans shall be treated as
     one arrangement.  In addition, two or more cash or deferred arrangements
     may be considered as a single arrangement for purposes of determining
     whether or not such arrangements shall be treated as one arrangement and as
     one plan for purposes of this subparagraph 7. A. and Code Sections
                                                -- --                  
     401(a)(4), 410(b) and 401(k).  For Plan Years beginning after December 31,
     1989, plans may be aggregated under this subparagraph 7. A. only if they
                                                           -- --             
     have the same plan year.

          Notwithstanding the above, an employee stock ownership plan described
     in Code Section 4975(e)(7) may not be combined with this Plan for purposes
     of determining whether the employee stock ownership plan or this Plan
     satisfies this subparagraph 7. A. 
                                 -- --                                        

                                     -14-

 
     and Code Sections 401(a)(4), 410(b) and 401(k).

          For the purpose of this subparagraph 7. A., if a Highly Compensated
                                               -- --                         
     Employee is a Participant under two or more cash or deferred arrangements
     of the Employer, all such cash or deferred arrangements shall be treated as
     one cash or deferred arrangement for the purpose of determining the actual
     deferral ratio with respect to such Highly Compensated Employee.  However,
     if the cash or deferred arrangements have different Plan Years, this
     paragraph shall be applied by treating all cash or deferred arrangements
     ending with or within the same calendar year as a single arrangement.

          B.   Actual Contribution Percentage Tests.  For each Plan Year, the
          --   ------------------------------------                          
     Plan shall satisfy one of the following tests:

               (1)  The "Actual Contribution Percentage" for the Highly
          Compensated Employee group shall not be more than the "Actual
          Contribution Percentage" of the Non-Highly Compensated Employee group
          multiplied by 1.25, or

               (2)  The excess of the "Actual Contribution Percentage" for the
          Highly Compensated Employee group over the "Actual Contribution
          Percentage" for the Non-Highly Compensated Employee group shall not be
          more than two percentage points.  Additionally, the "Actual
          Contribution Percentage" for the Highly Compensated Employee group
          shall not exceed the "Actual Contribution Percentage" for the Non-
          Highly Compensated Employee group multiplied by 2.

          However, to prevent the multiple use of the alternative method (2)
     described in this paragraph and Code Section 401(m)(9)(A), any Highly
     Compensated Employee eligible to make Salary Reduction Contributions or to
     receive Matching Company Contributions under this Plan shall have his
     actual contribution ratio reduced pursuant to Regulation 1.401(m)-2.  The
     provisions of Code Section 401(m) and Regulations 1.401(m)-1(b) and
     1.401(m)-2 are incorporated herein by reference.

          For the purposes of this Plan, "Actual Contribution Percentage" for a
     Plan Year means, with respect to the Highly Compensated Employee group and
     Non-Highly Compensated Employee group, the same as Actual Deferral
     Percentage as computed in subparagraph 7. A., but substituting "Matching
                                            -- --                            
     Company Contributions" for "Salary Reduction Contributions."

          For purposes of determining the "Actual Contribution Percentage" and
     the amount of Excess Aggregate Contributions pursuant to subparagraph 7.
                                                                           --
     D., only Company Matching Contributions contributed to the Plan prior to
     --                                                                      
     the end of the succeeding Plan Year shall be considered.

                                     -15-

 
          C.   Adjustment to Actual Deferral Percentage Tests. In the event that
          --   ----------------------------------------------
     the initial allocations of the Salary Reduction Contributions do not
     satisfy one of the tests set forth in subparagraph 7. A., the Administrator
                                                        -- -
     shall adjust Excess Contributions (i.e., Salary Reduction Contributions in
     excess of the limits established by the tests set forth in subparagraph 7.
                                                                             --
     A.) as set forth below:
     --                     

               (1)  On or before the fifteenth day of the third month following
          the end of each Plan Year, the Highly Compensated Employee having the
          highest actual deferral ratio shall have his portion of Excess
          Contributions distributed to him until one of the tests set forth in
          subparagraph 7. A. is satisfied, or until his actual deferral ratio
                       -- --                                                 
          equals the actual deferral ratio of the Highly Compensated Employee
          having the second highest actual deferral ratio.  This process shall
          continue until one of the tests set forth in subparagraph 7. A. is
                                                                    -- --   
          satisfied.  For each Highly Compensated Employee, the amount of Excess
          Contributions is equal to the Salary Reduction Contributions on behalf
          of such Highly Compensated Employee (determined prior to the
          application of this paragraph) minus the amount determined by
          multiplying the Highly Compensated Employee's actual deferral ratio
          (determined after application of this paragraph) by his Gross
          Compensation.  However, in determining the amount of Excess
          Contributions to be distributed with respect to an affected Highly
          Compensated Employee as determined herein, such amount shall be
          reduced by any Salary Reduction Contributions previously distributed
          to such affected Highly Compensated Employee for his taxable year
          ending with or within such Plan Year.

               With respect to the distribution of Excess Contributions as
          described above, such distribution:

                    (a)  may be postponed but not later than the close of the
               succeeding Plan Year;

                    (b)  shall be adjusted for Income; and

                    (c)  shall be designated by the Employer as a distribution
               of Excess Contributions (and Income).

               The determination and correction of Excess Contributions of a
          Highly Compensated Employee whose actual deferral ratio is determined
          under the family aggregation rules shall be accomplished by allocating
          the Excess Contributions for the family unit among the Family Members
          in proportion to the Elective Contributions of each Family Member that
          were combined to determine the group actual deferral ratio.

                                     -16-

 
          D.   Adjustment to Actual Contribution Percentage Tests.  In the event
          --   --------------------------------------------------               
     that the "Actual Contribution Percentage" for the Highly Compensated
     Employee group exceeds the "Actual Contribution Percentage" for the Non-
     Highly Compensated Employee group pursuant to subparagraph 7. B., the
                                                                -----     
     Administrator (on or before the fifteenth day of the third month following
     the end of the Plan Year, but in no event later than the close of the
     following Plan Year) shall direct the Trustee to distribute to the Highly
     Compensated Employee having the highest actual contribution ratio, his
     portion of Excess Aggregate Contributions (i.e., Matching Company
     Contributions in excess of the limits established by the tests set forth in
     subparagraph 7. B.) and Income allocable to such contributions or, if
                  -- --                                                   
     forfeitable, forfeit such non-Vested Excess Aggregate Contributions
     attributable to Matching Company Contributions (and Income allocable to
     such Forfeitures) until either one of the tests set forth in subparagraph
     7. B. is satisfied, or until his actual contribution ratio equals the
     -- --                                                                
     actual contribution ratio of the Highly Compensated Employee having the
     second highest actual contribution ratio.  This process shall continue
     until one of the tests set forth in subparagraph B. is satisfied.
                                                      --              
          Any distribution and/or Forfeiture of less than the entire amount of
     Excess Aggregate Contributions (and Income) shall be treated as a pro rata
     distribution and/or Forfeiture of Excess Aggregate Contributions and
     Income.  Distribution of Excess Aggregate Contributions shall be designated
     by the Employer as a distribution of Excess Aggregate Contributions (and
     Income).  Forfeitures of Excess Aggregate Contributions shall be treated in
     accordance with subparagraph 9. D.  However, no such Forfeiture may be
                                  -- --                                    
     allocated to a Highly Compensated Employee whose contributions are reduced
     pursuant to this subparagraph.

          Excess Aggregate Contributions shall be treated as Employer
     contributions for purposes of Code Sections 404 and 415 even if distributed
     from the Plan.

          For each Highly Compensated Employee, the amount of Excess Aggregate
     Contributions is equal to the Matching Company Contributions made pursuant
     to subparagraph 5. B. (determined prior to the application of this
                     -- --                                             
     paragraph) minus the amount determined by multiplying the Highly
     Compensated Employee's actual contribution ratio (determined after
     application of this paragraph) by his Gross Compensation.  The actual
     contribution ratio must be rounded to the nearest one-hundredth of one
     percent.  In no case shall the amount of Excess Contribution with respect
     to any Highly Compensated Employee exceed the amount of Matching Company
     Contributions made pursuant to subparagraph 5. B. on behalf of such Highly
                                                 -- --                         
     Compensated Employee for such Plan Year.

     8.   Selection of Investments; Employee Accounts and Allocation of
     --   -------------------------------------------------------------
          Benefits.
          --------

          A.   Establishment of Investment Funds.  With respect to each Plan
          --   ---------------------------------                            
     Year, the 

                                     -17-

 
     Company and Trustee may designate and describe one or more investment funds
     available for the allocation of Participants' accounts. Subject to
     Paragraph 13., the Trustee shall have the responsibility to decide the
               ---
     allocation of contributions which shall be made to the available Funds. The
     Company may delegate this responsibility to each Participant in a
     consistent and nondiscriminatory manner. In the event the Company so
     delegates the investment responsibility to Participants, each Participating
     Employee shall have the opportunity to designate the manner in which his
     account will be allocated among the available Funds, in accordance with the
     provisions of subparagraph 8. B.
                                -- --

          B.   Selections.  The designation by a Participant of the allocation
          --   ----------
     of his account among the available investment funds may be made from time
     to time, with such frequency and in accordance with such procedures as
     established by the Trustee and applied in a uniform nondiscriminatory
     manner. Any such procedure shall be communicated to the Participants and
     designed with the intention of permitting the Participants to exercise
     control over the assets in their respective accounts within the meaning of
     Section 404(c) of the Employee Retirement Income Security Act and the
     regulations promulgated thereunder. If and to the extent that a Participant
     shall fail to designate an allocation of his account under this
     subparagraph 8.B., the Trustee shall select a Fund or Funds to which such
                  ----
     amount shall be allocated. Otherwise, the Company shall instruct the
     Trustee to allocate and invest the assets of the Trust in accordance with
     the Participant's selections.

          If and to the extent that the account of a Participant or Beneficiary
     herein is directed to be invested pursuant to this paragraph, no person who
     is otherwise a fiduciary hereunder shall be liable to the directing
     Participant or Beneficiary for any particular loss, for failure to
     diversify assets, or in any other respect regarding such directed
     investment.  No investment shall be directed by a Participant or
     Beneficiary, nor made by the Trustee even if so directed, which would
     directly or indirectly inure to the benefit of the Company or which would
     constitute a prohibited transaction under applicable law and regulations.

          C.   Separate Records.  The Trustee shall maintain a separate account
          --   ----------------                                                
     in the name of each Participating Employee and each Beneficiary having a
     share in the Trust.  Separate records shall be kept of:

               (1)  the portion of each Participating Employee's share or
          account resulting from Company contributions made pursuant to a salary
          reduction agreement (such amounts to be recorded in a "Salary
          Reduction Contribution Account");

               (2)  the portion of each Participating Employee's share or
          account resulting from Matching Company Contributions intended to
          supplement amounts contributed pursuant to a salary reduction
          agreement (such amount to be recorded 

                                     -18-

 
          in a "Matching Company Contribution Account");

               (3)  the portion of each Participating Employee's share or
          account resulting from the Company's Discretionary Contributions (such
          amounts to be recorded in a "Company Discretionary Contribution
          Account").

               (4)  the portion of each Participating Employee's share or
          account resulting from the Participating Employee's Rollover
          Contribution (such amount to be recorded in a "Rollover Contribution
          Account").

     To that end, wherever in this Agreement reference is made to the "share" or
     "account" of a Participating Employee, the word "share" or "account" where
     the context so permits, shall be deemed to refer severally to the Salary
     Reduction Contribution Account, the Company Matching Contribution Account,
     the Company Discretionary Contribution Account, and the Rollover
     Contribution Account, each such account being adjusted for income and
     expense credited or charged as hereinafter described.

          D.   Allocation of Income and Expenses.  As of each Revaluation Date,
          --   ---------------------------------                               
     all income of the Trust for the period since the preceding Revaluation Date
     shall be credited to, and all losses and expenses of the Trust for such
     period shall be charged to, the various Accounts maintained by the Trustee
     for the Participating Employees and Beneficiaries.  Such credits and
     charges shall be made in proportion to the value of the respective
     Participating Employee and Beneficiary Accounts as of the preceding
     Revaluation Date (after recording all credits and charges which would
     otherwise be made based on Account balances as of the preceding Revaluation
     Date).  Further, the Trustee may adjust in a nondiscriminatory and
     consistent manner the credits and charges which would otherwise be made
     based on Account balances as of the preceding Revaluation Date to take into
     account inter-Fund transfers, periodic contributions made on behalf of
     Participants, repayments of Participant loans or borrowing by Participants,
     Rollover contributions, or any other transactions occurring since the
     preceding Revaluation Date.

          Any loan extended by the Trustee to a Participant pursuant to
     Paragraph 11. hereinbelow shall be deemed, for purposes of allocation of
               ---                                                           
     income, as an earmarked investment made for such Participant's benefit.
     Accordingly, all interest or other earnings attributable to such loan shall
     be allocated and credited exclusively to the account of the Participant to
     whom such loan was made.

          E.   Revaluation of Assets.  As of each Revaluation Date, the Trustee
          --   ---------------------                                           
     shall revalue the various Accounts maintained by the Trustee for the
     Participating Employees and Beneficiaries, to the end that such Employee
     and Beneficiary Accounts will reflect any increase or decrease in fair
     market value of the assets of the Trust as of such date.  Any such increase
     or decrease in market value shall be apportioned in the same manner 

                                      -19-

 
     that income, expenses, and losses are to be apportioned in accordance with
     the provisions of this Paragraph 8.
                                      --

          F.   List of Participants.  On or about the Anniversary Date ending
          --   --------------------                                          
     each Plan Year, the Company shall deliver to the Trustee a list of all
     Employees eligible on such date to participate herein, to whom Compensation
     was paid or payable for such year, together with a statement of the amount
     of such Compensation, and the amount by which such Compensation was reduced
     pursuant to a salary reduction agreement.

          G.   Allocation of Contributions.  The Trustee shall credit to the
          --   ---------------------------                                  
     Salary Reduction Contribution Account of each Participant, from the
     Company's current contribution, an amount equal to the amount set forth in
     the salary reduction agreement in effect with such Participant.

          The Trustee shall credit to the Matching Company Contribution Account
     of each Participant who makes Salary Reduction Contributions, an amount
     equal to the amount required to be contributed pursuant to Paragraph 5. B.
                                                                          -- --

          As of the Anniversary Date ending each Plan Year for which the Company
     shall make a Discretionary contribution hereunder, the Trustee shall credit
     to the Company Discretionary Account of each Participating Employee
     employed by the Company on such day and who has completed at least one (1)
     Hour of Service during such Plan Year (irrespective of whether such
     Participant has made a Salary Reduction Contribution), an amount which
     bears the same ratio to the total of the Company's Profit-Sharing
     Contribution as such Employee's Gross Compensation for such year shall bear
     to the aggregate of the Gross Compensation of all Participating Employees
     for such year.

          In the case of a Participating Employee who is entitled to have
     credited to his account a portion of a Company Discretionary contribution
     for such year but whose employment is terminated after the close of such
     year and before such contribution has been made to the Trust and such
     credit effected, such credit shall be effected as though such Employee's
     employment had not terminated.

          In addition, from time to time the Trustee shall credit to the other
     accounts of each Employee the amounts contributed by him to the Plan which
     constitute Rollover Contributions.

          H.   Limitation on Annual Additions.  If the Participant does not
          --   ------------------------------                              
     participate in, and has never participated in another qualified plan
     maintained by the employer or a welfare benefit fund, as defined in Section
     419(e) of the Code maintained by the employer, or an individual medical
     account, as defined in Section 415(1)(2) of the Code, maintained by the
     employer, which provides an annual addition as defined in 

                                      -20-

 
     subparagraph 8. J.(6), the amount of annual additions which may be credited
                  -- - 
     to the Participant's account for any limitation year will not exceed the
     lesser of the maximum permissible amount or any other limitation contained
     in this Plan. If the employer contribution that would otherwise be
     contributed or allocated to the Participant's account would cause the
     annual additions for the limitation year to exceed the maximum permissible
     amount, the amount contributed or allocated will be reduced so that the
     annual additions for the limitation year will equal the maximum permissible
     amount.

          Prior to determining the Participant's actual compensation for the
     limitation year, the employer may determine the maximum permissible amount
     for a Participant on the basis of a reasonable estimation of the
     Participant's compensation for the limitation year, uniformly determined
     for all Participants similarly situated.  As soon as is administratively
     feasible after the end of the limitation year, the maximum permissible
     amount for the limitation year will be determined on the basis of the
     Participant's actual compensation for the limitation year.  If as a result
     of forfeitures or as a result of exceeding the maximum permissible amount,
     there is an excess amount the excess will be disposed of as follows:

               (1)  Any nondeductible voluntary employee contributions, to the
          extent they would reduce the excess amount, will be returned to the
          Participant;

               (2)  If after the application of subparagraph (1) an excess
          amount still exists, and the Participant is covered by the Plan at the
          end of the limitation year, the excess amount in the Participant's
          account will be used to reduce employer contributions (including any
          allocation of forfeitures) for such Participant in the next limitation
          year, and each succeeding limitation year if necessary;

               (3)  If after the application of subparagraph (1) an excess
          amount still exists, and the Participant is not covered by the Plan at
          the end of a limitation year, the excess amount will be held
          unallocated in a suspense account. The suspense account will be
          applied to reduce employer contributions for all remaining
          Participants in the next limitation year, and each succeeding
          limitation year if necessary; and

               (4)  If a suspense account is in existence at any time during a
          limitation year pursuant to this section, it will not participate in
          the allocation of the trust's investment gains and losses.  If a
          suspense account is in existence at any time during a particular
          limitation year, all amounts in the suspense account must be allocated
          and reallocated to Participants' accounts before any employer or
          Employee contributions may be made to the Plan for that limitation
          year.  Excess amounts may not be distributed to Participants or former
          Participants.

                                      -21-

 
          I.   Combination With Other Plans.  This section applies if, in
          --   ----------------------------                              
     addition to this Plan, the Participant is covered under another qualified
     defined contribution plan maintained by the employer, a welfare benefit
     fund, as defined in Section 419(e) of the Code maintained by the employer,
     or an individual medical account, as defined in Section 415(1)(2) of the
     Code, maintained by the employer, which provides an annual addition as
     defined in subparagraph  8. J.(6), during any limitation year.  The annual
                                 --                                            
     additions which may be credited to a Participant's account under this Plan
     for any such limitation year will not exceed the maximum permissible amount
     reduced by the annual additions credited to a Participant's account under
     the other plans and welfare benefit funds for the same limitation year.  If
     the annual additions with respect to the Participant under other defined
     contribution plans and welfare benefit funds maintained by the employer are
     less than the maximum permissible amount and the employer contribution that
     would otherwise be contributed or allocated to the Participant's account
     under this Plan would cause the annual additions for the limitation year to
     exceed this limitation, the amount contributed or allocated will be reduced
     so that the annual additions under all such plans and funds for the
     limitation year will equal the maximum permissible amount.  If the annual
     additions with respect to the Participant under such other defined
     contribution plans and welfare benefit funds in the aggregate are equal to
     or greater than the maximum permissible amount, no amount will be
     contributed or allocated to the Participant's account under this Plan for
     the limitation year.

          Prior to determining the Participant's actual compensation for the
     limitation year, the employer may determine the maximum permissible amount
     for a Participant in the manner described in subparagraph 8. H.  As soon as
                                                               -- --            
     is administratively feasible after the end of the limitation year, the
     maximum permissible amount for the limitation year will be determined on
     the basis of the Participant's actual compensation for the limitation year.
     If as a result of forfeitures or as a result of exceeding the maximum
     permissible amount, a Participant's annual additions under this Plan and
     such other plans would result in an excess amount for a limitation year,
     the excess amount will be deemed to consist of the annual additions last
     allocated, except that annual additions attributable to a welfare benefit
     fund or individual medical account will be deemed to have been allocated
     first regardless of the actual allocation date.  If an excess amount was
     allocated to a Participant on an allocation date of this Plan which
     coincides with an allocation date of another plan, the excess amount
     attributed to this Plan will be the product of:

               (a)  the total excess amount allocated as of such date, times

               (b)  the ratio of (i) the annual additions allocated to the
          Participant for the limitation year as of such date under this Plan to
          (ii) the total annual additions allocated to the Participant for the
          limitation year as of such date under this and all the other qualified
          defined contribution plans.

                                      -22-

 
          Any excess amount attributed to this Plan will be disposed in the
     manner described in subparagraph 8. H.
                                      -- --

          If the employer maintains, or at any time maintained, a qualified
     defined benefit plan covering any Participant in this Plan, the sum of the
     Participant's defined benefit plan fraction and defined contribution plan
     fraction will not exceed 1.0 in any limitation year.  The annual additions
     which may be credited to the Participant's account under this Plan for any
     limitation year will be reduced or limited by the Trustee in a uniform and
     nondiscriminatory manner in order to effect the foregoing limitation.

          J.   Section 415 Definitions.
          --   ----------------------- 

               (1)  Annual additions:  The sum of the following amounts credited
          to a Participant's account for the limitation year:

                    (a)  employer contributions,

                    (b)  Employee contributions,

                    (c)  forfeitures, and

                    (d)  amounts allocated, after March 31, 1984, to an
               individual medical account, as defined in Section 415(1)(2) of
               the Code, which is part of a pension or annuity plan maintained
               by the employer are treated as annual additions to a defined
               contribution plan.  Also amounts derived from contributions paid
               or accrued after December 31, 1985, in taxable years ending after
               such date, which are attributable to post-retirement medical
               benefits, allocated to the separate account of a key employee, as
               defined in Section 419A(d)(3) of the Code, under a welfare
               benefit fund, as defined in Section 419(e) of the Code,
               maintained by the employer are treated as annual additions to a
               defined contribution plan.

               For this purpose, any excess amount applied under subparagraphs
          8. H. or 8. I. in the limitation year to reduce employer contributions
          -- --    -- --                                                        
          will be considered annual additions for such limitation year.

               (2)  Compensation:  A Participant's Earned Income, wages,
          salaries, and fees for professional services and other amounts
          received for personal services actually rendered in the course of
          employment with the employer maintaining the Plan (including, but not
          limited to, commissions paid salesmen, compensation for services on
          the basis of a percentage of profits, commissions on insurance
          premiums, tips and bonuses), and excluding the following:

                                      -23-

 
                    (a)  Employer contributions to a plan of deferred
               compensation which are not includible in the Employee's gross
               income for the taxable year in which contributed, or employer
               contributions under a simplified employee pension plan to the
               extent such contributions are deductible by the Employee, or any
               distributions from a plan of deferred compensation;

                    (b)  Amounts realized from the exercise of a nonqualified
               stock option, or when restricted stock (or property) held by the
               Employee either becomes freely transferable or is no longer
               subject to a substantial risk of forfeiture;

                    (c)  Amounts realized from the sale, exchange or other
               disposition of stock acquired under a qualified stock option; and

                    (d)  Other amounts which received special tax benefits, or
               contributions made by the employer (whether or not under a salary
               reduction agreement) towards the purchase of an annuity described
               in Section 403(b) of the Code (whether or not the amounts are
               actually excludible from the gross income of the Employee).

               For purposes of applying the limitations of this article,
          compensation for a limitation year is the compensation actually paid
          or includible in gross income during such limitation year.

               Notwithstanding the preceding sentence, compensation for a
          participant in a defined contribution plan who is Disabled is the
          compensation such participant would have received for the limitation
          year if the Participant had been paid at the rate of compensation paid
          immediately before becoming Disabled; such imputed compensation for
          the Disabled Participant may be taken into account only if the
          Participant is not a Highly Compensated Employee and contributions
          made on behalf of said Participant are nonforfeitable when made.

               (3)  Defined benefit fraction: A fraction, the numerator of which
          is the sum of the Participant's projected annual benefits under all
          the defined benefit plans (whether or not terminated) maintained by
          the employer, and the denominator of which is the lesser of 125
          percent of the dollar limitation determined for the limitation year
          under Sections 415(b) and (d) of the Code or 140 percent of the
          highest average compensation, including any adjustments under Section
          415(b) of the Code.

               (4)  Defined contribution dollar limitation:  $30,000 or if
          greater, one-fourth of the defined benefit dollar limitation set forth
          in Section 415(b)(1) of

                                      -24-

 
          the Code as in effect for the limitation year.

               (5)  Defined contribution fraction:  A fraction, the numerator of
          which is the sum of the annual additions to the Participant's account
          under all the defined contribution plans (whether or not terminated)
          maintained by the employer for the current and all prior limitation
          years (including the annual additions attributable to the
          Participant's nondeductible employee contributions to all defined
          benefit plans, whether or not terminated, maintained by the employer,
          and the annual additions attributable to all welfare benefit funds, as
          defined in Section 419(e) of the Code, and individual medical
          accounts, as defined in Section 415(1)(2) of the Code, maintained by
          the employer), and the denominator of which is the sum of the maximum
          aggregate amounts for the current and all prior limitation years of
          service with the employer (regardless of whether a defined
          contribution plan was maintained by the employer).  The maximum
          aggregate amount in any limitation year is the lesser of 125 percent
          of the dollar limitation determined under Sections 415(b) and (d) of
          the Code in effect under Section 415(c)(1)(A) of the Code or 35
          percent of the Participant's compensation for such year.

               (6)  Employer:  For purposes of subparagraphs 8. H., 8. I. and 8.
                                                             -- --  -- --     --
          J., employer shall mean the employer that adopts this Plan, and all
          --                                                                 
          members of a controlled group of corporations (as defined in Section
          414(b) of the Code as modified by Section 415(h)), all commonly
          controlled trades or businesses (as defined in Section 414(c) as
          modified by Section 415(h)) or affiliated service groups (as defined
          in Section 414(m)) of which the adopting employer is a part, and any
          other entity required to be aggregated with the employer pursuant to
          regulations under Section 414(o) of the Code.

               (7)  Excess amount:  The excess of the Participant's annual
          additions for the limitation year over the maximum permissible amount.

               (8)  Highest average compensation:  The average compensation for
          the three consecutive Years of Service with the employer that produces
          the highest average.

               (9)  Limitation year:  A calendar year, or the 12-consecutive
          month period elected by the employer pursuant to action of the Board.

               (10) Maximum permissible amount:  The maximum annual addition
          that may be contributed or allocated to a participant's account under
          the Plan for any limitation year shall not exceed the lesser of:

                    (a)  the defined contribution dollar limitation, or

                                      -25-

 
                    (b)  25 percent of the Participant's compensation for the
               limitation year.

               The compensation limitation referred to in (b) shall not apply to
          any contribution for medical benefits (within the meaning of Section
          401(h) or Section 419A(f)(2) of the Code) which is otherwise treated
          as an annual addition under Section 415(l)(1) or 419A(d)(2) of the
          Code.

               If a short limitation year is created because of an amendment
          changing the limitation year to a different 12-consecutive month
          period, the maximum permissible amount will not exceed the defined
          contribution dollar limitation multiplied by the following fraction:

                 Number of months in the short limitation year
                 ---------------------------------------------
                                      12

               (11)  Projected Annual Benefit:  The annual retirement benefit
          (adjusted to an actuarially equivalent straight life annuity if such
          benefit is expressed in a form other than a straight life annuity) or
          qualified joint and survivor annuity to which the Participant would be
          entitled under the terms of the Plan assuming:

                     (a)  the Participant will continue employment until Normal
               Retirement Age under the Plan (or current age, if later), and

                     (b)  the Participant's compensation for the current
               limitation year and all other relevant factors used to determine
               benefits under the Plan will remain constant for all future
               limitation years.

     9.   Retirement and Severance.
     --   ------------------------ 

          A.   Normal Retirement, Etc.  Upon the attainment by a Participant of
          --   -----------------------                                         
     the Normal Retirement Age of sixty-five (65), such Participant's account
     shall be fully vested and nonforfeitable.  In the event that the employment
     of a Participating Employee shall terminate at any time due to the death or
     Disability of such Participating Employee, such Participant's account shall
     be fully vested and nonforfeitable from and after the date of termination
     of employment.  Payment of benefits under the Plan to or on behalf of said
     Participant shall be made in accordance with the provisions of Paragraph
     10. below.
     ---       

          B.   Vested Benefits; Termination of Employment.  The portion of a
          --   ------------------------------------------                   
     Participating Employee's share in the Trust allocated to the Salary
     Reduction 

                                      -26-

 
     Contribution Account and the Rollover Contribution Account shall at all
     times be fully and immediately vested in such Employee. This portion,
     together with the vested portion of the Matching Company Contribution
     Account and the Company Discretionary Contribution Account, determined in
     accordance with the schedule set forth below, depending upon such
     Participant's Vesting Years of Service completed to the date of termination
     of employment shall be paid to or on behalf of such Participant at such
     time and in the manner provided under the further terms of the Plan.

          The vesting schedule applicable to a Participant's Matching Company
     Contribution Account and Company Discretionary Contribution Account shall
     be as follows:

 
 
                                                  Vested
          Vesting Years of Service              Percentage
          ------------------------              ----------
                                              
          Less than 1 year                         0%
          1 or more, but less than 2              20%
          2 or more, but less than 3              40%
          3 or more, but less than 4              60%
          4 or more, but less than 5              80%
          5 years or more                        100%
 

          Any amount not vested under the foregoing vesting schedule shall
     remain as an unallocated suspense account until the Anniversary Date upon
     which said Participant has incurred five consecutive One-Year Breaks in
     Service, which said amount shall thereupon constitute a forfeiture and
     shall be applied as provided in subparagraph D. hereinbelow.
                                                  --              
     Notwithstanding the foregoing sentence, the amount not vested under the
     above vesting schedule shall constitute a forfeiture as of the time of
     distribution of the vested benefit.  If a Participant terminates employment
     with the Company at a time when his vested account balance is zero, he will
     be deemed to have received a distribution of his entire vested account
     balance upon his termination of employment.

          In the case of a terminated Participating Employee who has incurred
     five consecutive One-Year Breaks in Service, Vesting Years of Service after
     such break shall not be taken into account in determining the vested
     percentage of his account which accrued prior to such five consecutive One-
     Year Breaks in Service.  In the case of a Participating Employee whose
     interest in the Plan has been distributed on termination of participation
     and was not repaid pursuant to the terms of subparagraph C. below, any
                                                              --           
     service after the distribution date will not increase the amount of the
     Participant's non-forfeitable benefit in the Plan as computed at the time
     of distribution.  Separate accounts for the pre-break and post-break
     portions of such person's interest in the Plan 

                                      -27-

 
     will be maintained, if and to the extent necessary to properly reflect the
     provisions of this subparagraph.

          C.   Repayment of Prior Distributions.  If a Participating Employee
          --   --------------------------------
     who has separated from service with the Company and received a distribution
     under the Plan shall return to the employment of the Company before
     incurring five consecutive One-Year Breaks in Service, any amount
     previously declared as a forfeiture (unadjusted by any later gains or
     losses) shall be reinstated to the Participant's account upon repayment by
     the Participant of the full amount of the distribution (unadjusted by any
     later gains or losses). Such repayment must be made before the Anniversary
     Date ending the Plan Year within which the Participant incurs a fifth
     consecutive One-Year Break in Service. If a Participant who is deemed to
     have received a distribution of his vested account balance because his
     vested account balance was zero returns to the employment of the Company
     before incurring five consecutive One-Year Breaks in Service, any amount
     previously declared as a forfeiture shall be reinstated to the
     Participant's account. Funds needed in any Plan Year to reinstate the
     amount previously forfeited by a re-employed Participant shall be provided
     first by forfeitures occurring during that Plan Year, and second, if
     necessary, by the Company by way of a separate Plan contribution. In such
     event, upon a subsequent termination of employment or retirement, the
     Participant's vested interest shall be determined in accordance with the
     foregoing vesting schedule as if no previous separation from service had
     occurred.

          D.   Treatment of Forfeitures.  The nonvested portion of a
          --   ------------------------                             
     Participant's account under the Plan shall constitute a forfeiture.  Any
     such forfeiture with respect to a Company Discretionary Contribution
     Account shall be reallocated to the accounts of those persons who, on the
     Anniversary Date ending the Plan Year during which the forfeiture occurred
     are eligible to participate in Company Discretionary contributions to the
     Plan for such Plan Year, and shall be allocated in the same manner as
     Company Discretionary contributions to the Plan are allocated pursuant to
     subparagraph 8. G. hereinabove.  Any such forfeiture of a Participant's
                  -- --                                                     
     Matching Company Contribution Account shall be used to reduce the Company's
     Matching Company Contributions to the Plan, and shall not be used to
     increase the benefits of the Participants and Beneficiaries.

     10.  Distribution of Benefits.
     ---  ------------------------ 

          A.   Notice By Company.  The Company shall certify to the Trustee, in
          --   -----------------                                               
     the event of termination of the employment of any Participant, the date of
     such termination.  The Company shall also certify to the Trustee the date
     of death of any Participant.  The Trustee shall rely on such certification
     in determining the extent to which such Participant, or his Beneficiary,
     shall be entitled to benefits under the Plan.

          B.   Form of Payment.  The amount payable to the Participant (or his
          --   ---------------             
     or her

                                      -28-

 
     Beneficiary) shall be paid in the form of a cash lump sum.

          C.   Timing of Payment.  A Participant who terminates employment after
          --   -----------------                                                
     attainment of the Normal Retirement Age shall receive or commence to
     receive his benefit within 60 days after the Anniversary Date following his
     termination of employment.  A Participant who terminates employment prior
     to his attainment of the Normal Retirement Age shall have the option to
     receive, at his or her election, a distribution of his or her entire
     interest in the form of a cash lump sum as soon as administratively
     feasible after the Participant's termination of employment with the
     Company.  If the Participant's vested interest in the Plan has never
     exceeded $3,500, the entire benefit shall be distributed to the Participant
     in a cash lump sum payment as soon as administratively feasible.  In no
     event shall payments be delayed in violation of Section 401(a)(14) of the
     Code.

          Notwithstanding the foregoing, a Participant's Salary Reduction
     Account shall not be distributed earlier than: (i) termination of
     employment, death, or Disability; (ii) termination of the Plan without
     establishment of a successor plan; (iii) attainment of age 59-1/2; (iv)
     financial hardship as provided in Paragraph 6. above; (v) the sale or other
                                                 --                             
     disposition by the Company of substantially all of its assets used in a
     trade or business to an unrelated entity, but only with respect to
     Employees who continue employment with the acquiring entity; or (vi) the
     sale or other disposition by the Company of its interest in a subsidiary to
     an unrelated entity but only with respect to Employees who continue
     employment with the subsidiary.

          D.   Other Rules for Commencement and Duration of Benefits.  This
          --   -----------------------------------------------------       
     subparagraph only applies to Participant's who remain in the employment of
     the Company beyond the calendar year in which they attain age 70-1/2 and to
     Participant's who are eligible to receive distribution of their benefit in
     a form other than a cash lump sum. The entire interest in the Plan of any
     Participating Employee must be, or commence to be, distributed before April
     1 of the calendar year following the calendar year in which the
     Participating Employee attains age 70-1/2. Benefits distributed hereunder
     shall be distributed over a period not to exceed the life of the
     Participant, the life of the Participant and his designated Beneficiary,
     the life expectancy of the Participating Employee, or the joint life
     expectancy of the Participating Employee and his designated Beneficiary. If
     the Participant's entire interest is to be distributed in a form other than
     a lump sum, then the amount to be distributed each year must be at least
     equal in amount to the quotient obtained by dividing the Participant's
     entire interest by the lesser of (i) the applicable life expectancy (ii) if
     the Participant's spouse is not the designated Beneficiary, the applicable
     divisor determined from the table set forth in Q&A-4 of Section 
     1.401(a)(9)-2 of the Proposed Regulations or such other successor
     regulation or publication which may be announced by the Secretary of the
     Treasury. For purposes of this computation, the life expectancy of the
     Participant may be recalculated no more frequently than annually, but the
     life expectancy of a nonspouse Beneficiary may not be recalculated.

                                      -29-

 
          E.   Death Benefits; Beneficiary Designation; Distribution of Death
          --   --------------------------------------------------------------
     Benefits.  In the event of the death of a Participant in the Plan, his
     --------                                                              
     accrued benefit shall be paid in full as soon as practicable to his
     surviving spouse, as his Beneficiary.  Notwithstanding the foregoing,
     however, a Participant may designate a Beneficiary other than the
     Participant's spouse if (1) the spouse has waived his or her right to be
     the Participant's Beneficiary in accordance with this subparagraph; or (2)
     the Participant has no spouse; or (3) the spouse cannot be located.

          In such event, the designation of a Beneficiary shall be made on a
     form satisfactory to the Company.  A Participant may at any time revoke his
     designation of a Beneficiary or change his Beneficiary by filing written
     notice of such revocation or change with the Company.  However, the
     Participant's spouse must again consent in writing to any such change or
     revocation.  Any consent by the Participant's spouse to waive any rights to
     the death benefit must be in writing, must acknowledge the effect of such
     waiver, and be witnessed by a Plan representative or a notary public.  In
     the event that no valid designation of Beneficiary exists at the time of
     the Participant's death, and the Participant has no surviving spouse, the
     death benefit shall be payable to his estate.

          In the event that payments are made to a Beneficiary, on account of
     the death of a Participant (or the death of a Participant's spouse), the
     entire interest of the Participant shall be distributed to such Beneficiary
     within five years after said death.

          F.   Segregated Accounts.  Amounts credited to the accounts of
          --   -------------------                                      
     Participants whose employment has terminated or Beneficiaries which are not
     paid out may be held with other assets of the Trust or may be held
     separately from the assets held for the benefit of other Participating
     Employees.  If so segregated, the Trustee shall invest such segregated
     accounts in savings accounts, certificates of deposit, Treasury bills,
     bonds, or similar interest-bearing investments, regardless of the
     investment policy adopted by the Trustee respecting the balance of the
     Trust assets.  In so doing, the Trustee shall not discriminate in favor of
     one or some retired Employees or Beneficiaries as against one or some other
     retired Employees or Beneficiaries.  Each such payee shall be credited or
     charged with appropriate adjustments for earnings, losses, and revaluations
     of the segregated amount being held for his benefit; all such adjustments
     shall be made as of each Anniversary Date, in the same manner as
     adjustments to other assets of the Trust.  Nothing in this paragraph,
     however, shall entitle such payee to share in any Company contributions to
     the Trust in which he would not otherwise be entitled to share under the
     provisions of this Agreement.

          G.   Location of Participant or Beneficiary Unknown. In the event that
          --   ----------------------------------------------
     all, or any portion, of the distribution payable to a Participant or his
     Beneficiary hereunder shall, at the expiration of five (5) years after it
     shall become payable, remain unpaid solely by reason of the inability of
     the Administrator, after sending a registered letter, return receipt

                                      -30-

 
     requested, to the last known address, and after further diligent effort, to
     ascertain the whereabouts of such Participant or his Beneficiary, the
     amount so distributable shall be reallocated in the same manner as
     forfeitures are allocated pursuant to subparagraph 9. D. hereinabove.  In
                                                        -- --                 
     the event a Participant or Beneficiary is located subsequent to his benefit
     being reallocated, such benefit shall be restored.

          H.   Special Distribution Rules Applicable to Qualified Domestic
          --   -----------------------------------------------------------
     Relations Order.  In the event that all, or any portion of the amounts
     ---------------                                                       
     credited to the accounts of a Participant are required to be paid to an
     alternate payee in accordance with the terms of any Qualified Domestic
     Relations Order ("QDRO"), as that term is defined in Paragraph 12. below,
                                                                    ---       
     the Trustee shall distribute to such designated alternate payee all amounts
     required under the QDRO regardless of whether the Participant would be
     entitled to a distribution of his account by virtue of termination of
     employment or attainment of retirement age.  The alternate payee under the
     QDRO shall have the option to receive, at his or her election, the entire
     amount required by the QDRO in the form of a cash lump sum as soon as
     administratively feasible after the Company's receipt and verification of
     the QDRO.

          I.   Direct Rollovers.  This subparagraph applies to distributions
          --   ----------------             
     made on or after January 1, 1993. Notwithstanding any provision of the Plan
     to the contrary that would otherwise limit a distributee's election under
     this subparagraph, a distributee may elect, at the time and in the manner
     prescribed by the Plan Administrator, to have any portion of an eligible
     rollover distribution paid directly to an eligible retirement plan
     specified by the distributee in a direct rollover.

          For purposes of this Subparagraph 8.I., the following definitions
                                            ----                           
     shall apply:

               (1)  Eligible rollover distribution:  An eligible rollover
          distribution is any distribution of all or any portion of the balance
          to the credit of the distributee, except that an eligible rollover
          distribution does not include:  any distribution that is one of a
          series of substantially equal periodic payments (not less frequently
          than annually) made for the life (or life expectancy) of the
          distributee or the joint lives (or joint life expectancies) of the
          distributee and the distributee's designated beneficiary, or for a
          specified period of ten years or more; any distribution to the extent
          such distribution is required under Section 401(a)(9) of the Code; and
          the portion of any distribution that is not includible in gross income
          (determined without regard to the exclusion of net unrealized
          appreciation with respect to employer securities).

               (2)  Eligible retirement plan:  An eligible retirement plan is an
          individual retirement account described in Section 408(a) of the Code,
          an individual retirement annuity described in Section 408(b) of the
          Code, an annuity 

                                      -31-

 
          plan described in Section 403(a) of the Code, or a qualified trust
          described in Section 401(a) of the Code, that accepts the
          distributee's eligible rollover distribution. However, in the case of
          an eligible rollover distribution to the surviving spouse, an eligible
          retirement plan is an individual retirement account or individual
          retirement annuity.

               (3)  Distributee:  A distributee includes an Employee or former
          Employee.  In addition, the Employee's or former Employee's surviving
          spouse and the Employee's or former Employee's spouse or former spouse
          who is the alternate payee under a qualified domestic relations order,
          as defined in Section 414(p) of the Code. are distributees with regard
          to the interest of the spouse or former spouse.

               (4)  Direct rollover:  A direct rollover is a payment by the Plan
          to the eligible retirement plan specified by the distributee.

     11.  Loans to Participating Employees.
     ---  -------------------------------- 

     The Trustee shall have the power to make loans from the Trust to all
Participating Employees and Beneficiaries (who are also parties in interest as
defined in ERISA) in accordance with the terms of this Paragraph 11.  All such
                                                                 ---          
loans will be administered by the Plan Administrator.  All loan applications
will be submitted to the Plan Administrator.  The maximum amount of any such
loan, when combined with all existing loans to the Participant from the Plan,
all other plans of the Employer, and any plan maintained by an employer
described in subsections (b), (c), (m) and/or (o) of Section 414 of the Code,
shall not exceed the lesser of:  (i) $50,000 (reduced by the excess of the
highest outstanding loan balance from the Plan and other plans maintained by the
Company, during the period of one year ending on the day before the date of the
loan under consideration, over the outstanding balance of all such loans on the
date of the loan under consideration), or (ii) one-half of the nonforfeitable
account balance of the Employee under such plan or plans.  The minimum amount of
any such loan shall be $1,000.  Each such loan shall be repayable, by its terms,
within five years of the date of the loan; provided, however, that a loan used
to acquire a dwelling unit which within a reasonable time is to be used as the
principal residence of the Participant may be for a term in excess of five
years.  All such loans may be secured by:  (i) one-half of the Participant's
nonforfeitable account, and/or by (ii) such other security as deemed necessary
under the circumstances by the Plan Administrator for the full protection of the
Plan and Trust.  All loans shall be made at a rate of interest not less than the
then prevailing rate of interest in the Duluth, Minnesota, area which would be
available under the circumstances from an institutional lender.  Each loan shall
be evidenced by a promissory note, executed by the borrowing Participant,
requiring level amortization of such loan with payments of principal and
interest at stated intervals not less frequently than quarterly.  The failure of
a Participant to repay a loan in accordance with the terms of the promissory
note within ten (10) days after written demand by the Plan Administrator

                                      -32-

 
shall constitute a default. Upon default, the Trustee may accelerate the
Participant's obligation to repay the loan. If said loan is not then paid in
full, the Trustee may satisfy said loan by treating the amount of the
outstanding balance due under said loan as a distribution to the Participant of
said amount at the earliest time that such amount may be distributable to the
Participant under the terms of the Plan. If the loan is secured by additional
security, the Trustee may execute on the security in accordance with local law.
The Trustee may also take such other steps as permitted by law to protect the
Plan Assets. The outstanding principal balance due on a loan shall be offset
against and shall reduce any amounts otherwise payable to the Participant under
the Plan. The Trustee is authorized to follow instructions given by the Plan
Administrator in connection with all loans granted pursuant to this Paragraph
11.  The Plan Administrator may adopt such other rules and procedures as it
- ---                                                                        
deems appropriate to administer the granting of loans and/or to comply with all
applicable government regulations.

     A Participant must obtain the consent of his or her spouse, if any, to use
of the account balance as security for the loan.  Spousal consent shall be
obtained no earlier than the beginning of the 90-day period that ends on the
date on which the loan is to be so secured.  The consent must be in writing,
must acknowledge the effect of the loan, and must be witnessed by a plan
representative or notary public.  Such consent shall thereafter be binding with
respect to the consenting spouse or any subsequent spouse with respect to that
loan.  A new consent shall be required if the account balance is used for
renegotiation, extension, renewal, or other revision of the loan.

     12.  Spendthrift Clause.
     ---  ------------------ 

     Except as otherwise provided in this paragraph, the rights of a Participant
or Beneficiary to receive payments or benefits hereunder shall not be subject to
alienation or assignment, and shall not be subject to anticipation, encumbrance
or claims of creditors.  Notwithstanding the foregoing, the Plan shall pay
benefits in accordance with the terms of any Qualified Domestic Relations Order,
provided that such Order (i) does not require the Plan to provide any type or
form of benefits, or any option, that is not otherwise provided hereunder, (ii)
does not require the Plan to provide increased benefits, and (iii) does not
require the payment of benefits to an alternate payee which are required to be
paid to another alternate payee under another order previously determined to be
a Qualified Domestic Relations Order.  For purposes of the preceding sentence, a
"Domestic Relations Order" shall mean any judgment, decree or order (including
approval of a property settlement agreement) which relates to the provision of
child support, alimony payments, or marital property rights to a spouse, former
spouse, child, or other dependent of a Participant and is made pursuant to a
state domestic relations law.  "Qualified Domestic Relations Order" shall mean a
Domestic Relations Order which creates or recognizes the existence of an
alternate payee's right to, or assigns to an alternate payee the right to,
receive all or a portion of the benefits payable with respect to a Participant
under this Plan and which clearly  specifies (i) the name and the last known
mailing address of the Participant and each 

                                      -33-

 
alternate payee covered by the Order, (ii) the amount or percentage of the
Participant's benefits to be paid by the Plan to each such alternate payee, or
the manner in which such amount or percentage is to be determined, (iii) the
number of payments or period to which such Order applies, and (iv) each plan to
which such Order applies. A distribution by the estate of a deceased Participant
or Beneficiary to an heir or legatee of a right to receive payments hereunder
shall not be deemed an alienation, assignment or anticipation for the purposes
of this Paragraph 12.
                  ---

     13.  Administration of Trust.
     ---  ----------------------- 

     In administering this Plan and Trust, the Trustee and the Company shall
administer the same for the benefit of all Participating Employees and
Beneficiaries as herein provided, without discrimination in favor of one or some
Participating Employees or Beneficiaries as against one or some other
Participating Employees or Beneficiaries.

     Whenever action is required by the Company hereunder, the same may be taken
by any individual designated as agent for the purpose.  The Company shall notify
the Trustee of any change of agent.  The Trustee shall be entitled to rely upon
information or instructions received from the agent of the Company whose
authority to act was last certified by the Trustee.  Any information or
instruction from the Company to the Trustee shall be in writing and shall be
effective upon delivery to the Trustee.  The Trustee shall be under no duty or
responsibility to inquire into the acts or omissions of the Company, nor shall
the Trustee have any liability therefor.  Should it become necessary to perform
some act hereunder and there is neither direction in this Plan nor information
nor instructions from the Company on file with the Trustee relating thereto, and
no such information or instructions can be obtained after reasonable inquiry,
the Trustee shall have full power and authority to act in the Trustee's
discretion, consistently with the purpose of this Plan; and in so acting or in
following any instructions from the Company, the Trustee shall be fully
protected and shall be absolved from all liability except from fraud or bad
faith.

     The duties, powers and responsibilities of the Trustee shall be limited as
specifically provided herein.  No person serving as a Trustee hereunder shall be
liable or responsible to anyone for any matter or thing whatsoever, provided
only that he has acted in good faith.

     The Trustee in performing any act hereunder shall be entitled to rely upon
any affidavit, certificate, letter, notice, telegram or other paper or document
believed by the Trustee to be genuine and upon any information or evidence
believed by the Trustee to be sufficient; and the Trustee shall be protected in
all payments hereunder if made in good faith and without actual knowledge of the
happening of an event or a change in conditions which would affect such
payments.

                                      -34-

 
     The Trustee shall make any sale, investment or reinvestment of the Trust
property or any part thereof which the Company may from time to time direct, and
if such direction be given, the Trustee shall have no obligation with respect
thereto except for failure to carry out such direction.  Without limiting the
generality of the foregoing, the Company may direct the investment of Trust
funds in stock and/or obligations of the Company and in stock and/or obligations
of the Trustee (if a corporate Trustee then be acting in such capacity under
this Trust).  The Trustee shall have no liability for any depreciation or loss
with respect to any property acquired by the Trustee pursuant to such direction,
and shall have no duty to review or to make recommendations with respect
thereto.

     14.  Trustee's Administrative Powers.
     ---  ------------------------------- 

     The Trustee shall receive, hold, invest and reinvest contributions to the
Trust fund and shall make disbursements from the Trust fund pursuant to the
terms of this Plan.  Subject to the consent of the Trustee, the Company shall
have the right to make its contributions hereunder in property to the Trustee.
The Trustee shall make payments from the Trust fund only to such persons, in
such manner, at such times, and in such amounts as may be specified in written
directions from the Company and not otherwise, and the Trustee shall be fully
protected in making payments under the direction of the Company.  For purposes
of accounting and valuation, the records of the Trust shall be maintained on a
cash receipts and disbursements basis.  The Trustee from time to time shall
capitalize unexpended income and add the same to the principal of the Trust.

     Subject only to such instructions, rules and restrictions as may from time
to time be adopted by the Company and communicated to the Trustee, the Trustee
shall have the following powers and rights in addition to those invested in the
Trustee by law:

          (a)  Investment Powers.  To hold, manage and control the assets of the
               -----------------                                                
     Trust, during the continuance of the Trust.  The Trustee shall have full
     power without any court order to improve, lease for any term irrespective
     of the duration of the Trust, rent, sell, exchange, hold, control, invest
     and reinvest the same in such manner and upon such terms as the Trustee
     deems best, including (without limitation of these powers) the power to
     purchase shares in investment trusts and stock in investment corporation,
     irrespective of any statutes or rules or practices of courts now or
     hereafter in force limiting the investments of trust companies or trustees
     generally, with full power to convert realty into personalty and personalty
     into realty.  The Trustee hereunder shall not be required to dispose of any
     property held hereunder in order to diversify the investments of the Trust
     or because such holdings are of a kind not ordinarily considered as proper
     investments for trust estates; nor shall the Trustee be precluded from
     acquiring property which results in a nondiversification of the investments
     of the Trust or which is of a kind not ordinarily considered as proper
     investments for trust estates; therefore, the Trustee is granted the 

                                      -35-

 
     right to retain property so long as the Trustee shall deem such investments
     reasonably sound, and to acquire such property as the Trustee deems to be a
     reasonably sound investment, regardless of the proportion of the Trust
     which it represents and regardless of whether it is of a type ordinarily
     deemed proper for trust investments. The Trustee is authorized to hold cash
     uninvested at any time and from time to time. No purchaser from nor lender
     to the Trustee need see to the application of the purchase or loan money to
     the purposes of the Trust, but the receipt of the Trustee shall be a
     complete discharge to any such person. The Trustee acting hereunder shall
     not be held responsible for any loss sustained by the Trust through any
     error of judgment made in good faith, but shall be liable only for the
     Trustee's own willful misconduct. The Trustee hereunder shall not be
     personally liable upon any contract of indebtedness of or claim against the
     Trust or upon a mortgage, trust deed, note or other instrument executed
     under the provisions of this Plan.

          (b)  Borrowing.  To borrow money from the Trustee or others, upon such
               ---------                                                        
     terms and conditions, at any time or times, and for such purposes of the
     Trust as the Trustee may deem proper or desirable provided that such
     borrowing does not result in a prohibited transaction under Code Section
     4975(c).  For sums borrowed, the Trustee may issue the Trustee's promissory
     notes as Trustee and secure the payment thereof by mortgaging or pledging
     any part or all of the Trust assets.

          (c)  Holding and Transferring Real Estate.  To take and hold title to
               ------------------------------------                            
     real estate or interests therein in the Trustee's name or in the name of
     the Trustee's nominee without disclosing the Trust; and in accepting title
     to the real estate, neither the Trustee nor the Trustee's nominee shall be
     held to have assumed the payment of any encumbrances thereon, nor any
     responsibility as to the validity of the title conveyed to or held by the
     Trustee or the Trustee's nominee.  All conveyances executed and delivered
     by the Trustee or the Trustee's nominee shall be without covenants of
     warranty except as against the Trustee's own acts.

          (d)  Voting and Related Powers.  To vote any stocks, bonds, or other
               -------------------------                                      
     securities, to give general or special powers of attorney with or without
     power of substitution; to exercise any conversion privileges, subscription
     rights or other options and to make any payments incidental thereto; to
     consent to or otherwise participate in corporate reorganizations or other
     changes affecting corporate securities and to delegate discretionary powers
     and to pay any assessments or charges in connection therewith; and
     generally to exercise any of the powers of an owner with respect to stocks,
     bonds, securities or other property held in the Trust.

          (e)  Claims by or Against the Trust.  To sue or defend in any suit or
               ------------------------------                                  
     legal proceedings by or against the Trust.  The Trustee shall have full
     power in the Trustee's discretion to compound, compromise and adjust all
     claims and demands in favor of or 

                                      -36-

 
     against the Trust upon such terms as the Trustee may deem best. In the
     administration of the Trust, the Trustee shall not be obligated to take any
     action which may subject the Trustee to any expense or liability unless the
     Trustee is first indemnified to the Trustee's satisfaction for all expenses
     and liabilities, including attorneys' fees, which the Trustee may incur in
     connection with such action.

          (f)  Nominee.  To register any investment held in the Trust in the
               -------                                                      
     Trustee's own name or in the name of a nominee and to hold any investment
     in bearer form; provided, however, that the books and records of the
     Trustee shall at all times show that all such investments are part of the
     Trust fund, and provided further that such registration or holding shall
     neither increase nor decrease the liability of the Trustee.

          (g)  Employment of Agents.  To employ such agents, attorneys-in-fact,
               --------------------                                            
     experts and investment and legal counsel, including any firm or corporation
     with which the Trustee may be associated as a partner, director,
     stockholder or otherwise, and to delegate discretionary powers to or to
     rely upon information or advice furnished by such agents, attorneys-in-
     fact, experts or counsel.

          (h)  Execution of Instruments.  To execute and deliver any and all
               ------------------------                                     
     documents of transfer and conveyance and any and all other instruments that
     may be necessary or appropriate to carry out the powers herein granted, and
     to perform any and all acts that may be necessary or convenient in the
     proper administration of the Trust.

          (i)  Collective Investment Trust.  To commingle assets of the Trust
               ---------------------------                                   
     with assets of other trusts, which in each case form a part of a pension or
     profit-sharing plan qualified under the Code and constitute an exempt trust
     within the meaning of the Code, (i) through the medium of any collective
     investment trust for employee benefit trusts established and maintained by
     any bank, or, to the extent permitted by law, or (ii) through the medium of
     any collective investment trust for employee benefit trusts established and
     maintained by any trust company.  To the extent of the equitable share of
     this Trust in any such investment trust, the instrument establishing such
     investment trust, as the same has been or may be amended, and the trust
     maintained thereunder, shall be deemed a part of this Plan and Trust as if
     fully set forth herein.

          (j)  Necessary Acts.  To do all acts whether or not expressly
               --------------                                          
     authorized which may be necessary or proper for the protection of the
     property held hereunder or for the carrying out of any duty under this Plan
     or under the Trust fund.

     15.  Holding of Trust Assets.
     ---  ----------------------- 

     Except as otherwise provided hereinabove, all the assets in the Trust shall
be held 

                                      -37-

 
collectively for all the Participants and Beneficiaries with no physical
division thereof until such time as distribution is actually made by the
Trustee.

     16.  Nonliability of Successor Trustee.
     ---  --------------------------------- 

     Each successor Trustee may accept as complete and correct and may rely upon
any accounting which shall have been made by or on behalf of any Trustee
hereunder prior to the date upon which such successor Trustee shall have
qualified as a Trustee under this instrument, and may rely upon any statement or
representation made by any Trustee then or theretofore acting hereunder as to
the assets comprising the Trust or as to any other fact bearing upon the prior
administration of the Trust created herein; and such successor Trustee shall not
be subject to any liability by reason of having accepted and relied upon such
accounting, statement or representation in case it is subsequently established
that the same was incomplete, inaccurate or untrue.  No successor Trustee
hereunder shall be subject to any liability or responsibility with respect to
any act or omission of any other Trustee nor shall any successor Trustee have
any duty to enforce or to seek to enforce any claims of any kind against any
predecessor Trustee on account of or in connection with any act or omission of
any Trustee hereunder.

     17.  Decision of Majority of Trustees to Govern.
     ---  ------------------------------------------ 

     Except as otherwise expressly provided, when there are three Trustees
authorized to act in any particular, the agreement of a majority of the Trustees
shall be required, and when there are two Trustees authorized to act in any
particular, the agreement of both Trustees shall be required.  Each Trustee
shall be liable only for his own acts in the administration of this Trust.  No
Trustee shall be in any way or to any extent liable to the Participants,
Beneficiaries or others for anything done hereunder by his Co-Trustee to which
he did not actively consent or of which he did not actively approve.

     18.  Accounts.
     ---  -------- 

     The Trustee shall keep accurate and detailed accounts of all investments,
receipts and disbursements and other transactions hereunder, and all accounts,
books and records relating thereto shall be open to inspection by any person
designated by the Board of Directors of the Company at all reasonable times.
Not later than one hundred twenty (120) days after the end of each Plan Year,
and within sixty (60) days after the effective date of the removal or
resignation of a Trustee, the Trustee shall file with the Company a written
report setting forth all investments, receipts, disbursements, and other
transactions effected by the Trustee from the date of the prior such report to
the close of such Plan Year, or the date of removal or resignation of a Trustee,
as the case may be. Such report shall contain an exact description of all
securities and investments held at the close of such Plan Year or the effective
date of such removal or

                                      -38-

 
resignation of a Trustee, as the case may be, and the cost of each item thereof,
as carried on the books of the Trustee. Upon the expiration of ninety (90) days
from the date of filing such report, the Trustee, including a Trustee who
resigned or was removed, shall be forever released and discharged from any
liability or accountability to anyone as respects the propriety of the Trustee's
acts or transactions shown in such report, except with respect to any such acts
or transactions as to which the Company shall within such 90-day period file
with the Trustee a written statement claiming fraud or bad faith on the part of
the Trustee; and neither the Company nor any other person shall have the right
to demand or be entitled to any further or different accounting by the Trustee.

     19.  Removal or Resignation of Trustee.
     ---  --------------------------------- 

     Any Trustee hereunder may be removed by resolution of the Board of
Directors of the Company upon delivery to such person of a certified copy of
such resolution of removal.  Any Trustee hereunder may resign as Trustee, upon
written notice to that effect, delivered to the Company.  Such removal or
resignation shall become effective upon the date specified in such resolution or
such notice, as the case may be, which shall be not less than fifteen (15) days
subsequent to the delivery of such certified copy of resolution or such notice.
In the event of the removal, resignation, death or inability to serve of any
Trustee hereunder, a successor shall be appointed by resolution of the Board, a
certified copy of which resolution shall be delivered to such successor.  In the
event of the removal, resignation, death or inability to serve of any Trustee
hereunder after the Company shall have gone out of business or  ceased to exist
or been dissolved, voluntarily or involuntarily, or had a receiver or trustee in
bankruptcy appointed, a successor may be appointed by election by a majority in
interest of the Participants and Beneficiaries then having an interest in the
Trust.  A successor Trustee, upon accepting such appointment, shall become
vested with the same powers, duties, privileges, and immunities as if such
Trustee had been originally named in this Plan as a Trustee.  In case of the
removal, resignation, death or inability to serve of a Trustee, said Trustee or
his personal representative shall forthwith turn over to the remaining or
succeeding Trustees all accounts and records in such Trustee's possession, and
shall execute such instruments as may be necessary to terminate such
trusteeship.  No bond shall be required of the Trustee named in this Plan or any
of the Trustee's successors.

     20.  Allocation of Responsibilities.
     ---  ------------------------------ 

          A.   Administrative Responsibilities.  The Company is the Named
          --   -------------------------------                           
     Fiduciary which has the authority to control and manage the operation and
     administration of the Plan.  The Company shall make such rules,
     regulations, interpretations, and shall take such other actions to
     administer the Plan as the Company may deem appropriate.  In administering
     the Plan, the Company shall act in a nondiscriminatory manner with 

                                      -39-

 
     respect to Plan Participants and Beneficiaries, and shall at all times
     discharge its duties with respect to the Plan in accordance with applicable
     fiduciary standards.

          B.   Management of Plan Assets.  The Company is the Named Fiduciary
          --   -------------------------                                     
     with respect to control over and management of the Plan's assets only to
     the extent that it (i) shall appoint one or more Trustees to hold the
     assets of the Plan in trust, (ii) shall appoint one or more Investment
     Managers for any Plan assets and enter into an investment management
     agreement with each Investment Manager it appoints, and (iii) shall
     exercise its authority to direct the sale, investment or reinvestment of
     Plan assets in accordance with Paragraph 13. hereinabove.  The Company
                                              ---                          
     shall be responsible for diversifying the investments of the Plan only to
     the extent that said authority to direct investments is exercised, and the
     Trustee and the Investment Managers, if any, shall be responsible for
     diversifying the specific investments in accounts under their management.

          C.   Trustee and Investment Managers.  The Trustee shall have the
          --   -------------------------------                             
     exclusive authority and discretion to control and manage the assets of the
     Plan held in trust by it, and shall be the Named Fiduciary with respect to
     such control and management, except to the extent that the Company
     exercises its authority to direct investment of the Plan's assets, or that
     the authority to manage such assets is allocated by the Company to one or
     more Investment Managers.  Each Investment Manager appointed by the Company
     shall have the authority to manage, including the power to acquire and
     dispose of, such assets of the Plan as are assigned to it by the Company.

          D.   Delegation of Fiduciary Responsibilities.  Except as otherwise
          --   ----------------------------------------                      
     expressly stated herein, the Company shall not allocate or delegate to any
     other person any of its duties and responsibilities hereunder.  The duties
     and responsibilities of the Company shall be carried out by the Company's
     Directors and officers, acting on behalf of and in the name of the Company
     in their capacities as such, and not as individual fiduciaries.  The
     Company is specifically prohibited from designating any Director or officer
     of the Company as a fiduciary and from allocating or delegating to any such
     person any of the fiduciary responsibilities of the Company.

     21.  Amendments.
     ---  ---------- 

     The Company reserves the right by action of its Board of Directors to amend
this Plan at any time without the consent of the Trustee, but no such amendment
shall cause or permit any portion of the corpus or income of the Trust to revert
to or become the property of or be used for the benefit of the Company.  Any
amendment which is necessary to bring this Trust into conformity with government
laws or regulations in order to qualify the Plan and Trust for tax exemption may
be made retroactively.  No amendment to this Plan may be made which would result
in a cutback of vested rights or rights to accrued benefits as provided in
Section 

                                      -40-

 
411(a)(10)(A) or 411(d)(6) of the Code. In the event that the vesting schedule,
if any, set forth in the Plan is amended, each Participant who has completed at
least three (3) Years of Service may elect to have his accrued benefit
determined under the vesting schedule in effect prior to the amendment.

     22.  Termination of Contributions.
     ---  ---------------------------- 

     The Company has established this Plan with the bona fide intention and
expectation that from year to year it will be able to and will deem it advisable
to make its contributions as herein provided.  However, the Company realizes
that circumstances not now foreseen or circumstances beyond its control may make
it either impossible or inadvisable to continue to make its contributions as
herein provided.  In the event the Company decides it is impossible or
inadvisable for it to continue to make its contributions as herein provided, the
Company shall have the right to terminate its contributions.

     In the event of complete termination of contributions by the Company, with
or without formal action by the Company, the Company shall make no further
contributions under the Plan, the Plan and Trust shall remain in existence, and
all the provisions of the Plan and Trust shall remain in force which are
necessary in the opinion of the Trustee, other than the provisions for
contributions by the Company and any provisions requiring forfeiture of a
Participating Employee's share in the Trust (the shares in the Trust of each
Participating Employee shall become fully vested in such Participant, regardless
of the length of his employment or his participation, upon such termination of
contributions); and all of the assets in the Trust on the date specified in such
resolutions shall be held, administered and distributed by the Trustee in the
manner provided herein.

     23.  Termination of Trust.
     ---  -------------------- 

     In the event that the Company's contributions to the Trust have been
terminated completely in accordance with the provisions of Paragraph 22. above,
                                                                     ---       
the Board shall also have the power to terminate the Plan and Trust completely
by appropriate resolutions specifying the date of such termination, certified
copies of which shall be delivered to the Trustee.  Upon a complete or partial
termination of the Plan and Trust, with or without formal action by the Company,
any provision requiring forfeiture of the share in the Trust of a Participating
Employee affected by such termination shall become void, and the share in the
Trust of each such Participating Employee shall become fully vested in him.
After payment of all expenses and after adjustment of Participants' and
Beneficiaries' shares for expenses, profits, losses and any other adjustments
necessary to reflect accurately such shares in the Trust in accordance with the
provisions hereof, there shall be paid to each Participant and each Beneficiary
the amount of his share in the Trust, in accordance with the further terms of
this Plan.

                                      -41-

 
     24.  Merger or Consolidation of Plan, Transfer of Plan Assets.
     ---  ------------------------------------------------- ------ 

     In the event of any merger or consolidation with, or transfer of assets and
liabilities to, any other plan, provision shall be made to the effect that each
Participant and Beneficiary in this Plan will be entitled, after the merger,
consolidation or transfer, to a benefit equal to or greater than the benefit to
which he would have been entitled under this Plan, immediately prior to said
merger, consolidation or transfer, as if the Plan had terminated at such time.

     25.  Top-Heavy Provisions.
     ---  -------------------- 

          A.   Determination of Top-Heavy Status.  As of each determination
          --   --------------------------------- 
     date, the Company shall compute the aggregate amounts allocated to the
     accounts of all "key employees" of the Company. The term "key employee"
     shall mean any Employee, former Employee, or beneficiary thereof who, at
     any time during the Plan Year or any of the four preceding Plan Years, is
     or was (i) an officer of the Employer having an annual Compensation greater
     than fifty percent (50%) of the dollar limitation then in effect under
     Section 415(b)(1)(A) of the Code, (ii) one of the ten Employees having an
     annual Compensation greater than the dollar limitation then in effect under
     Section 415(c)(1)(A) of the Code and owning (or considered as owning within
     the meaning of Section 318 of the Code) the largest interests in the
     Company, (iii) a five percent (5%) owner of the Company or (iv) a one
     percent (1%) owner of the Company who has annual Compensation from the
     Company in excess of $150,000. For purposes of determining percentage
     ownership in the foregoing sentence, the rules of Section 416(i)(1)(B) of
     the Code shall apply and the rules of Sections 414(b), (c), and (m) shall
     not apply. If the aggregate amount allocated to the accounts of all key
     employees exceeds sixty percent (60%) of the aggregate amount allocated to
     the accounts of all Participants, then the Plan will be deemed to be top-
     heavy for the Plan Year next following such Anniversary Date (and in the
     case of the initial Plan Year, for the Plan Year ending with such
     Anniversary Date). For purposes of determining the aggregate amounts
     allocated to the accounts of Participants, there shall be added any amount
     of Company contributions required to be made for the Plan Year ending on
     the determination date (unless this Plan is not subject to the minimum
     funding requirements of Section 412 of the Code). The present value of
     accrued benefits shall be determined based upon the interest and mortality
     rates specified in the defined benefit plan. The account balances
     attributable to a Participant who has not performed any services for the
     Company at any time during the five-year period ending on any determination
     date shall be disregarded. For purposes of making the above determination,
     there shall be considered (i) all other qualified plans of the Company in
     which a key employee is a participant, (ii) all other plans which enable
     this Plan or plans described in (i) above to meet the requirements of
     Sections 401(a)(4) or 410 of the Code, and (iii) all other qualified plans
     which may have been terminated but which were

                                      -42-

 
     maintained by the Employer within the five-year period ending on the
     determination date. There shall also be considered any distributions made
     with respect to any Participant within a five-year period ending on the
     determination date. At the option of the Company, any other qualified plans
     maintained by it may be included in the group of plans for purposes of
     determining the top-heavy status of the Plan, provided that the group of
     plans would continue to meet the requirements of Sections 401(a)(4) and 410
     of the Code with such plans which are added at the option of the Company
     being taken into account. If any plans of the Company are aggregated with
     this Plan as described in the preceding sentence, this Plan shall be deemed
     to be top-heavy only if the aggregate present value of accrued benefits of
     key employees in the aggregated group of plans exceeds 60 percent of the
     aggregate present value of accrued benefits of all employees in the
     aggregated group of plans. For purposes of determining present value of
     accrued benefits, the rules of Section 416(g) shall apply. Accrued benefits
     shall be determined under the method which is used for accrual purposes for
     all plans of the Company, or if there is no such method, then under the
     slowest accrual rate permitted under Section 411(b)(1)(C) of the Code.
     Determination date shall mean the last day of the preceding Plan Year.
     However, for the first Plan Year the determination date shall be the last
     day of that year. For purposes of determining whether an Employee is a key
     employee, "Compensation" shall mean compensation as defined in Section
     415(c)(3) of the Code, but including Salary Reduction Contributions made to
     this Plan.

          B.   Minimum Allocations.  For each Plan Year that the Plan is top-
          --   -------------------                                          
     heavy, there shall be allocated to the account of each Participant who is
     not a key employee and who is employed by the Company on the last day of
     the Plan Year, irrespective of whether he has completed 1,000 Hours of
     Service with the Company during the Plan Year, an amount not less than
     three percent (3%) of each such Participant's W-2 Compensation (without
     taking into account Social Security and similar contributions and
     benefits).  Notwithstanding the foregoing, if the contribution for any Plan
     Year made by the Company is less than three percent (3%) of the aggregate
     W-2 Compensation of all Participants, then the amount allocable to each
     nonkey employee shall be such lesser percentage.  If the Company maintains
     both a defined contribution plan and a defined benefit plan with a nonkey
     employee who participates, or could participate in both plans, then there
     shall be allocated to the account of each Participant who otherwise would
     be entitled to receive a minimum allocation as described above an amount
     not less than five percent (5%) of such Participant's W-2 Compensation (but
     without taking into account Social Security and similar contributions and
     benefits).  For purposes of this subparagraph C., all defined contribution
                                                   --                          
     plans of the Company shall be aggregated to the end that the percentage
     rules shall be satisfied if the aggregate contribution made to all defined
     contribution plans equals five percent (5%) of any nonkey Participant's W-2
     Compensation.

          C.   Effect on Section 415 Limitations.  If the Company maintains both
          --   ---------------------------------                                
     a 

                                      -43-

 
     defined contribution plan and a defined benefit plan with a Participant who
     participates, or could participate, in both plans, then for purposes of
     computing the defined contribution fraction and defined benefit fraction
     described in subparagraph 8. J. hereunder, the dollar limitation of
                               -- -
     Sections 415(b)(1)(A) and 415(c)(1)(A) shall be multiplied by 1.0 in lieu
     of 1.25, unless:

               (1)  the defined contribution plan allocates to the account of
          each Participant who is not a key employee not less than seven and
          one-half percent (7-1/2%) of each such Participant's W-2 Compensation
          (without taking into account Social Security and similar contributions
          and benefits); and

               (2)  the plan would not be top-heavy if 90 percent were
          substituted for 60 percent in subparagraph A. above.
                                                     --       

     26.  Expenses of Administration.
     ---  -------------------------- 

     The Trustee's compensation shall be fixed by agreement from time to time
with the Company; provided, however, that no person compensated as an Employee
of the Company shall be compensated as a Trustee hereunder.  The Company intends
to pay, in addition to the contributions hereinbefore provided for, any expenses
of administering the Trust, including the Trustee's compensation, if any, except
that any investment counsel fees incurred by the Trust, and any expenses
directly related to particular transactions involving purchases or sales of
property by the Trust or the production or collection of income, such as
transfer taxes, brokers' commissions, etc., shall be paid by the Trustee out of
the assets of the Trust.

     27.  Rights of Participants.
     ---  ---------------------- 

     Participating in this Plan and Trust shall not give any Participant any
right to be retained in the service of the Company or any right or claim to any
benefits hereunder unless such benefits have accrued under the terms and
provisions of this Plan.

     28.  Claims Procedure.
     ---  ---------------- 

     Claims for benefits under the Plan may be filed with the Plan Administrator
on forms supplied by it.  Written notice of the disposition of a claim shall be
furnished to the claimant within 90 days after the application is filed.  In the
event the claim is denied, the reasons for the denial shall be specifically set
forth in the notice in language calculated to be understood by the claimant,
pertinent provisions of the Plan shall be cited, and, where appropriate, an
explanation as to how the claimant can perfect the claim will be provided.  In
addition, the claimant shall be 

                                      -44-

 
furnished with an explanation of the Plan's claims review procedure, as
described below.

     Any Employee or Beneficiary who has been denied a benefit shall be entitled
to request the Plan Administrator to give further consideration to his claim by
filing with the Plan Administrator (on a form which may be obtained from the
Plan Administrator) a request for a hearing.  Such request, together with a
written statement of the reasons why the claimant believes his claim should be
allowed, shall be filed with the Plan Administrator no later than 60 days after
receipt of the written notification furnished by the Plan Administrator with
respect to the claim. The Plan Administrator shall then conduct a hearing within
the next 60 days, at which the claimant may be represented by an attorney or any
other representative of his choosing and at which the claimant shall have an
opportunity to submit written and oral evidence and arguments in support of his
claim. At the hearing (or prior thereto upon 5 business days written notice to
the Plan Administrator) the claimant or his representative shall have an
opportunity to review all documents in the possession of the Plan Administrator
which are pertinent to the claim at issue and its disallowance. Either the
claimant or the Plan Administrator may cause a court reporter to attend the
hearing and record the proceedings. In such event, a complete written transcript
of the proceedings shall be furnished to both parties by the court reporter. The
full expense of any such court reporter and such transcripts shall be borne by
the party causing the court reporter to attend the hearing. A final decision as
to the allowance of the claim shall be made by the Plan Administrator within 60
days of receipt of the appeal (unless there has been an extension of 60 days due
to special circumstances, provided the delay and the special circumstances
occasioning it are communicated to the claimant within the 60 day period). Such
communication shall be written in a manner calculated to be understood by the
claimant and shall include specific reasons for the decision and specific
references to the pertinent Plan provisions on which the decision is based.

     29.  Construction.
     ---  ------------ 

     It is intended that this Plan shall be construed so as to qualify as a tax-
free employees' profit-sharing plan and trust, contributions to which by the
Company shall be deductible from its net income.

     30.  Defense of Trust.
     ---  ---------------- 

     The Company shall have the right to defend the position of the Trust
created under this Plan as a tax-free profit-sharing trust.

     31.  Ohio Trust.
     ---  ---------- 

                                      -45-

 
     This Plan is executed and delivered in the State of Ohio and the Trust
hereby created shall be deemed an Ohio trust and shall in all respects be
construed and regulated by the laws of the State of Ohio.

     32.  Mistaken Contributions, Etc.
     ---  ----------------------------

     Except as otherwise provided herein, the assets of the Plan shall not inure
to the benefit of the Company, and shall be held for the exclusive purposes of
providing benefits to Participants and Beneficiaries and defraying reasonable
expenses of administering the Plan.  Notwithstanding the foregoing sentence:

          (a)  If a contribution is made by the Company under a mistake of fact,
     such contribution may be returned, at the discretion of the Company, within
     one (1) year after payment of such contribution.

          (b)  All contributions to the Plan are conditioned on initial
     qualification of the Plan under Section 401 of the Code.  If the Plan does
     not so qualify for any Plan Year for which a contribution is made, such
     contribution may be returned, at the discretion of the Company, within one
     (1) year after the date of denial of initial qualification of the Plan
     provided that the application for qualification is made by the time
     prescribed by law for filing the Employer's tax return for the taxable year
     in which the Plan is adopted, or such later date as the Secretary of the
     Treasury may prescribe.

          (c)  All contributions to the Plan are conditioned upon the
     deductibility thereof, for Federal income tax purposes, under Section 404
     of the Code.  If and to the extent that such deduction is disallowed, the
     Company's contribution (to the extent disallowed) may be returned, at the
     discretion of the Company, within one (1) year after the disallowance of
     the deduction.

     Earnings attributable to the contributions to be returned to the Company
will not be returned to the Company, but losses attributable to such
contributions will reduce the amount to be returned.  Notwithstanding the
foregoing, if the Plan fails to initially qualify under Section 401 of the Code,
the entire assets of the Plan may be returned to the Company.

     33.  Plan Administrator; Legal Agent.
     ---  ------------------------------- 

     The Company shall serve as the Plan Administrator and as the legal agent
for service of process upon the Plan, to be served at the following address:

                                FIRST AMENDMENT
                      TO THE ADVANSTAR COMMUNICATIONS INC.
                        EMPLOYEES' 401(k) PLAN AND TRUST
                        --------------------------------


                               (1993 RESTATEMENT)


     THIS FIRST AMENDMENT is made this 31st day of March, 1994, by ADVANSTAR
COMMUNICATIONS INC. (the "company") to the Advanstar Communications Inc.
Employees' 401(k) Plan and Trust (the "Plan"), which was restated in its
entirety in 1993.

     WHEREAS, the Omnibus Budget Reconciliation Act of 1993 requires that all
qualified plans limit the amount of participant compensation that may be taken
into account in determining allocations under said plans and it is desired to
incorporate such limitations into the Plan; and

     WHEREAS, the Company acquired Aster Publishing Corporation and the Company
wishes to clarify that participants in the Aster Publishing Corporation Profit-
Sharing Plan are permitted to participate in the Plan; and

     WHEREAS, the Company wishes to liberalize certain provisions relating to
the 401(k) provisions of the Plan, all as permitted by final Treasury
Regulations;

     NOW THEREFORE, Pursuant to the provisions of Paragraph 21. of the Plan,
                                                            --
said Plan is hereby amended, as follows:

     FIRST:  Effective January 1, 1994, subparagraph 2.(e) is hereby deleted in
                                                     -
its entirety, and the following new subparagraph 2.(e) is substituted in lieu
                                                 -
thereof:

     "(e) `Compensation' shall mean the total compensation paid by the Company
      ---                                                                     
     to an Employee for services rendered for the period under consideration
     (other than compensation in the form of qualified or previously qualified
     compensation) that is currently includible in gross income of the Employee
     for income tax purposes.  `Compensation' shall also include amounts that
     are not includible in income of the Employee under Code Section 125 (except
     for amounts not includible in income under Code Section 125 which are
     applied to the payment of medical insurance premiums on behalf of such
     Employee)."

     SECOND: Effective January 1, 1994, subparagraph 2.(j) is hereby deleted in
                                                     --                        
its entirety, and the following new subparagraph 2.(j) is substituted in lieu
                                                 --                          
thereof:

     "(j) `Gross Compensation' shall mean the total compensation paid by the
      ---
     Company to an Employee for services rendered for the period under
     consideration (other than compensation in the form of qualified or
     previously qualified compensation) that is currently includible in gross
     income of the Employee for income tax purposes, plus all amounts not
     includible in income of the Employee under Code Section 125 and all amounts
     deferred hereunder pursuant to a salary reduction agreement.

 
          For plan years commencing January 1, 1994 or later, the annual Gross
     Compensation of each Participant taken into account under the Plan for any
     plan year shall not exceed $150,000, as adjusted by the Commissioner of
     Internal Revenue for increases in the cost-of-living in accordance with
     Section 401(a)(17)(B) of the Code.  The cost-of-living adjustment in effect
     for a calendar year applies to any period, not exceeding 12 months, over
     which Gross Compensation is determined (determination period) beginning in
     such calendar year.  If a determination period consists of fewer than 12
     months, the annual compensation limit will be multiplied by a fraction, the
     numerator of which is the number of months in the determination period, and
     the denominator of which is 12.

          In determining the Gross Compensation of a Participant for purposes of
     this limitation, the rules of Section 414(q) of the Code shall apply,
     except in applying such rules, the term "family" shall include only the
     spouse of the Participant and any lineal descendants of the Participant who
     have not attained age 19 before the close of the year. If, as a result of
     the application of such rules, the adjusted $150,000 limitation is
     exceeded, then the limitation shall be prorated among the affected
     individuals in proportion to each such individual's Gross Compensation, as
     determined under this subparagraph prior to the application of this
     limitation."

     THIRD:  Effective January 1, 1993, Paragraph 4. is hereby deleted in its
                                                  --                         
entirety, and the following new Paragraph 4. is substituted in lieu thereof:
                                          --                                

          "4.  Plan Entry Requirements.
           --  ----------------------- 

          Each Employee of the Company shall enter the Plan on the first day of
     the calendar month next following the later to occur of the end of the 12-
     month period of service which constitutes a Year of Service with respect to
     such Employee and his attainment of age twenty-one (21). Notwithstanding
     the foregoing, if an Employee is a non-resident alien who receives no
     earned income (within the meaning of Section 911(d)(2) of the Code) from
     the Company which constitutes income from sources within the United States
     (within the meaning of Section 861(a)(3) of the Code), such Employee shall
     be ineligible to enter into a salary reduction agreement pursuant to
     subparagraph 5.A. hereof.
                  ----        

          Individuals who are United States citizens and who are employed by a
     foreign subsidiary corporation or a domestic subsidiary whose operations
     are largely foreign shall be considered as Employees of the Company and
     shall be permitted to participate in this Plan (including the right to
     enter into a salary reduction agreement) provided that the Company extends
     social security coverage to such individuals and further provided that such
     U.S. citizen employees are not provided contributions under a funded plan
     of deferred compensation by any other person with respect to compensation
     paid to such U.S. citizen employees by the foreign subsidiary or domestic
     subsidiary with largely foreign operations.

          With respect to an Employee who has met the eligibility requirements
     of the Plan
        
                                      -2-

 
     but who has incurred a One-Year Break in Service, such Employee shall be
     eligible to re-enter the Plan commencing immediately upon his return.  In
     the event an Employee who is not a member of an eligible class of employees
     becomes a member of an eligible class, such employee will participate
     immediately if such Employee has satisfied the minimum age and service
     requirements and would have otherwise previously become a Participant.  In
     the event that the eligibility of any person to participate in the Plan
     shall be disputed, the decision of the Trustee upon such eligibility shall
     be controlling.  For the purposes of enabling the Trustee to make such
     determination, all information available to the Company which shall be
     required by the Trustee shall be made available to the Trustee."

     FOURTH:   Effective January 1, 1994, subparagraph 6.B. (3) is hereby
                                                       ---
deleted in its entirety, and the following new subparagraph 6.B.(3) is
substituted in lieu thereof:

          "(3) Payment of tuition and related educational fees for the next 12
     months of post-secondary education for the Participant, his spouse,
     children, or dependents; or"

     FIFTH:    Effective January 1, 1989, subparagraph 7.A.(1) at page 17, is
                                                       -------
hereby deleted in its entirety, and the following new subparagraph 7.A.(1) is
                                                                   -------
substituted in lieu thereof:

          "(1) The combined actual deferral ratio for the family group (which
     shall be treated as one Highly Compensated Employee) shall be determined by
     aggregating Salary Reduction Contributions and Gross Compensation of all
     eligible Family Members (including Highly Compensated Employees)."

     SIXTH:    Effective January 1, 1994, subparagraph 8.H.(1) is hereby deleted
                                                       -------
in its entirety, and the following new subparagraph 8.H.(1) is substituted in
                                                    -------
lieu thereof:

          "(1) Any contributions made pursuant to a salary reduction agreement,
     to the extent they would reduce the excess amount, will be returned to the
     Participant;"

                                      -3-

 
     IN WITNESS WHEREOF, this First Amendment has been executed by the Company,
pursuant to action of its Board of Directors, as of the day and year first above
written.

                               SECOND AMENDMENT
                     TO THE ADVANSTAR COMMUNICATIONS INC.
                       EMPLOYEES' 401(K) PLAN AND TRUST
                       --------------------------------
                                        
                              (1993 RESTATEMENT)
                                        
     THIS SECOND AMENDMENT is made this 18th day of August, 1994, by and among
ADVANSTAR COMMUNICATIONS INC. (the "Company") and MARY ABOOD, TEUTA CENAJ, BYRON
GLIDDEN, DAVID MONTGOMERY, and PHILLIP STOCKER (collectively the "Trustee"), to
the Advanstar Communications Inc. Plan and Trust (the "Plan"), which was
restated in its entirety in 1993.

     Pursuant to the provisions of Paragraph 21. of the Plan, said Plan is
                                             --                           
hereby amended, effective the 1st day of September, 1994, by the deletion of
subparagraph 2 (w) in its entirety and the substitution of the following new
             -----                                                          
subparagraph 2 (w) in lieu thereof:
             -----                 

               "(w)  "Vesting Year of Service" shall mean a period of  twelve
          (12) consecutive months during which a Participating Employee either
          (i) completes at least One (1) Hour of Service and is employed on the
          last day of the twelve-month period, or (ii) completes at least One
          Thousand (1,000) Hours of Service without regard to employment on the
          last day of the twelve-month period.  Such twelve-month period shall
          be calculated with reference to the Employee's "Employment
          Commencement Date" (the first date of employment on which the Employee
          is credited with an Hour of Service with the Company), and subsequent
          twelve-month periods shall be calculated with reference to subsequent
          anniversaries of said Employment Commencement Date.

               The number of Hours of Service to be credited to an Employee for
          determining whether a Vesting Year of Service has been completed shall
          be computed on equivalencies based on periods of employment in
          accordance with Department of Labor Regulation (S)2530.200b-3(e) as
          follows:

               If an Employee is paid on a weekly basis, the Employee shall be
          credited with 45 Hours of Service for each week for which the Employee
          would otherwise be credited with at least one Hour of Service pursuant
          to subparagraph 2 (1).
                          ----- 

               If an Employee is paid on a bi-weekly basis, the Employee shall
          be credited with 90 Hours of Service for each such two-week period for
          which the Employee would otherwise be credited with at least one Hour
          of Service pursuant to subparagraph 2 (1).
                                              ------

               In determining Vesting Years of Service, service with Harcourt
          Brace Jovanovich, Inc. shall be considered as service with the
          Company.

 
               An Employee who ceases to be a Participant, but who remains in
          the employment of the company, shall continue to be credited with
          Vesting Years of Service under this Plan so long as he remains in the
          employment of the Company.  An Employee who was in the employment of
          the Company before he became an Employee for purposes of this Plan
          shall receive credit for Vesting Years of Service as though he had
          been an Employee during such prior period of employment with the
          Company."

     In no event shall any Participating Employee's Vesting Years of Service be
reduced by virtue of this amendment.  If a Participating Employee satisfied the
requirements for a Vesting Year of Service prior to this amendment for a
particular twelve-month period, the Participating Employee shall continue to
receive credit for a Vesting Year of Service for such period, notwithstanding
this amendment.

     IN WITNESS WHEREOF, this Second Amendment has been executed by the Company,
pursuant to action of its Board of Directors, and by the Trustee as of the day
and year first above written.

          Participant, if the Company determines that such action is necessary
          to insure that the Participant's annual additions for any Plan Year
          will not exceed the limitations of subparagraphs 8. H. or 8. I.
                                                           -- --    -- --
          hereinbelow, or to insure that the Actual Deferral Percentage Test
          described in Paragraph 7. hereinbelow is met for such Plan Year.  In
                                 --                                           
          any such event, the Company may pay to the Participant the amount
          which otherwise would have been paid prior to the Participant's
          election to reduce his salary, rather than as a contribution made
          pursuant to a salary reduction agreement.

               (6) A salary reduction agreement shall not provide for a
          reduction in excess of $7,000 (or such higher amount as determined by
          the Secretary pursuant to Section 415(d) of the Code) under all plans
          maintained by the Company with respect to any Employee's taxable year.

     B.  Matching Company Contributions.  Not later than the time prescribed by
     -   ------------------------------                                        
law for filing its federal income tax return including any extensions thereof)
for its current taxable year, the Company shall contribute to the Trustee, on
behalf of each Participant, as its Matching Company Contribution to the Trust
for the Plan Year which ends within or which is co-terminous with such taxable
year of the Company, to be held in trust, administered and distributed under the
terms of this Agreement, an amount to be determined as follows:

               (1) With respect to Salary Reduction Contributions up to the
          first two percent (2%) of the Participant's Compensation, the Matching
          Company Contribution shall be equal to 100% of the Salary Reduction
          Contribution;

               (2) With respect to Salary Reduction Contributions in excess of
          two percent (2%) of the Participant's Compensation and not in excess
          of six percent (6%) of the Participant's Compensation, the Matching
          Company Contribution shall be equal to 25% of such Salary Reduction
          Contribution; and

               (3) With respect to Salary Reduction Contributions in excess of
          six percent (6%) of the Participant's Compensation, there shall be no
          Matching Company Contribution.  In no event shall the Matching Company
          Contribution made on behalf of a Participant in a Plan Year exceed
          three percent (3%) of the Participant's Compensation.

     In determining the Matching Company Contribution, the computation of the
Salary Reduction Contribution as a percentage of Compensation shall be made on a
per payroll basis.

     Notwithstanding the foregoing, the Company shall not contribute to the Plan
as a Matching Company Contribution any amount that would cause the limitation
set forth in Paragraph 7. to be exceeded, considering only Matching Company
                       --                                                  
Contributions, rather than Salary Reduction Contributions

 
     C.  Discretionary Company Contributions.  Not later than the time
     -   -----------------------------------                          
prescribed by law for filing its federal income tax return (including extensions
thereof) for its current taxable year and for each succeeding taxable year, the
Company may contribute to the Trust fund, as its contribution to this Trust for
the Plan Year which ends within or which is co-terminous with such taxable year
of the Company, to be held in trust, administered and distributed under the
terms of this Agreement, an amount or amounts which the Company, in its sole
discretion may determine.  The Company may contribute such amount or amounts at
any time; and it may make such contribution in two or more installments.

     The Company shall determine by resolution of its Board of Directors and
communicate to the Trustee before the close of each Plan Year either (i) the
amount in dollars to be contributed for such year, or (ii) a formula by which
such amount may be determined.  These contributions shall be totally in the
discretion of the Company with respect to amount, timing and form, and they need
not be limited to the Employee group for a Plan Year, the average of the ratios,
calculated separately for each Participant in such group, of the amount of
Salary Reduction Contributions allocated to each participant's Salary Reduction
Contribution Account for such Plan Year to such Participant's Gross Compensation
for such Plan Year.  The actual deferral ratio for each Participant and the
"Actual Deferral Percentage" for each group shall be calculated to the nearest
one-hundredth of one percent.

     For the purpose of determining the actual deferral ratio of a Highly
Compensated Employee who is subject to the Family Member aggregation rules of
Code Section 414(q)(6) because such Participant is either a "five percent owner"
of the Employer or one of the ten (10) Highly Compensated Employees paid the
greatest "415 Compensation" during this year, the following shall apply:

               (1) The combined actual deferral ratio for the family group
          (which shall be treated as one Highly Compensated Employee) shall be
          determined by aggregating Salary Reduction Contributions and Gross
          Compensation of all eligible Family Members (including Highly
          Compensated Employees).

               (2) The Salary Reduction Contributions and Gross Compensation of
          all Family Members shall be disregarded for purposes of determining
          the "Actual Deferral Percentage" of the Non-Highly Compensated
          Employee group except to the extent taken into account in paragraph
          (1) above.

               (3) If a participant is required to be aggregated as a member of
          more than one family group in a plan, all Participants who are members
          of those family groups that include the Participant are aggregated as
          one family group in accordance with paragraphs (1) and (2) above.
