               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.   Incorporation of Documents by Reference.

          McLeodUSA Incorporated (the "Registrant") hereby incorporates by
reference into this Registration Statement the following documents filed by it
with the Commission:

          (a)  The Registrant's prospectus, dated December 1, 1997, filed with
               the Commission pursuant to Rule 424(b) under the Securities Act
               and which contains audited financial statements for the fiscal
               year ended December 31, 1996;

          (b)  All other reports filed with the Commission pursuant to Section
               13(a) or 15(d) of the Securities Exchange Act of 1934 (the
               "Exchange Act") since December 31, 1996; and

          (c)  The description of the Registrant's Class A Common Stock, $.01
               par value per share (the "Class A Common Stock"), contained in
               the Registrant's Registration Statement on Form 8-A filed with
               the Commission on May 24, 1996.

          In addition, all documents and reports filed by the Registrant
pursuant to Sections 13(a), 13(c), 14, or 15(d) of the Exchange Act, subsequent
to the date hereof and prior to the filing of a post-effective amendment which
indicates that all securities offered have been sold or which deregisters all
securities remaining unsold, shall be deemed to be incorporated by reference in
this Registration Statement and to be part hereof from the date of filing of
such documents or reports.  Any statement contained in a document incorporated
or deemed to be incorporated by reference herein shall be deemed to be modified
or superseded for purposes of this Registration Statement to the extent that a
statement contained herein or in any other subsequently filed document which
also is or is deemed to be incorporated by reference herein modifies or
supersedes such statement.  Any such statement so modified or superseded shall
not be deemed, except as so modified or superseded, to constitute a part of this
Registration Statement.

          To the extent that any proxy statement is incorporated by reference
herein, such incorporation shall not include any information contained in such
proxy statement which is not, pursuant to the Commission's rules, deemed to be
"filed" with the Commission or subject to the liabilities of Section 18 of the
Exchange Act.

ITEM 4.   DESCRIPTION OF SECURITIES.

          Not applicable (the Class A Common Stock is registered under Section
12 of the Exchange Act).

ITEM 5.   INTERESTS OF NAMED EXPERTS AND COUNSEL.

          Not applicable.

ITEM 6.   INDEMNIFICATION OF DIRECTORS AND OFFICERS.

          Under Section 145 of the Delaware General Corporation Law ("DGCL"), a
corporation may indemnify its directors, officers, employees and agents and its
former directors, officers, employees and agents and those who serve, at the
corporation's request, in such capacities with another enterprise, against
expenses (including attorneys' fees), as well as judgments, fines and
settlements in nonderivative lawsuits, actually and reasonably incurred in
connection with the defense of any action, suit or proceeding in which they or
any of them were or are made parties or threatened to be made parties by reason
of their serving or having served in such capacity.  The DGCL provides, however,
that such person must have acted in good faith and in a manner such person
reasonably believed to be in (or not opposed to) the best interests of the
corporation and, in the case of a criminal action, such person must have had no
reasonable cause to believe his or her conduct was unlawful.  In addition, the
DGCL does not permit indemnification in any action or suit by or in the right of
the corporation, where such person has been adjudged liable to the corporation,
unless, and only to the extent that, a court determines that such person fairly
and reasonably is entitled to indemnity for costs the court deems proper in
light of liability adjudication.  Indemnity is mandatory to the extent a claim,
issue or matter has been successfully defended.

          The Registrant's Amended and Restated Certificate of Incorporation
(the "Restated Certificate") provides that no director of the Registrant shall
be liable for breach of fiduciary duty as a director except for (1) any breach
of the directors' duty of loyalty to the Registrant or its stockholders; (2)
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of the law; (3) liability under Section 174 of the DGCL; or
(4) any transaction from which the director derived an improper personal
benefit.  The Restated Certificate also provides for the indemnification of
directors and officers to the fullest extent permitted by the DGCL.  Under the
Amended and Restated Bylaws of the Registrant, the Registrant is required to
advance expenses incurred by an officer or director in defending any such action
if the director or officer undertakes to repay such amount if it is determined
that the director or officer is not entitled to indemnification.  In addition,
the Registrant has entered into indemnity agreements with each of its directors
pursuant to which the Registrant has agreed to indemnify the directors as
permitted by the DGCL.  The Registrant has obtained directors and officers
liability insurance against certain liabilities, including liabilities under the
Securities Act.

                            *          *          *

          Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions or otherwise, the
Registrant has been advised that, in the opinion of the Commission, such
indemnification is against public policy as expressed in the Securities Act and
therefore is unenforceable.  In the event that a claim for indemnification
against such liabilities (other than for

                                      -2-
<PAGE>
 
the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the Registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question of whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

ITEM 9.   UNDERTAKINGS.

          The undersigned Registrant hereby undertakes:

          (a) To file, during any period in which offers or sales are being
          made, a post-effective amendment to this registration statement:

                        (i) To include any prospectus required by Section
               10(a)(3) of the Securities Act;

                        (ii) To reflect in the prospectus any facts or events
               arising after the effective date of the Registration Statement
               (or the most recent post-effective amendment thereof) which,
               individually or in the aggregate, represent a fundamental change
               in the information set forth in the Registration Statement;

                                      -4-
<PAGE>
 
                        (iii) To include any material information with respect
               to the plan of distribution not previously disclosed in the
               Registration Statement or any material change to such information
               in the Registration Statement.

               Provided, however, that paragraphs (a)(i) and (a)(ii) do not
          apply if the Registration Statement is on Form S-3 or Form S-8, and
          the information required to be included in a post-effective amendment
          by those paragraphs is contained in periodic reports filed by the
          Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act
          that are incorporated by reference in the Registration Statement.

          (b) That, for the purpose of determining any liability under the
          Securities Act, each such post-effective amendment shall be deemed to
          be a new registration statement relating to the securities offered
          therein, and the offering of such securities at that time shall be
          deemed to be the initial bona fide offering thereof.

          (c) To remove from registration by means of a post-effective amendment
          any of the securities being registered which remain unsold at the
          termination of the offering.

          The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the Registration Statement shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

          The undertaking concerning indemnification is set forth under the
response to Item 6.

          Box on Form W-2). Compensation is wages as defined in Code Section
          3401(a) and all other payments of compensation to an Employee by the
          Employer (in the course of the Employer's trade or business) for which
          the Employer is required to furnish the Employee a written statement
          under Code Sections 6041(d) and 6051(a)(3). Compensation must be
          determined without regard to any rules under Code Section 3401(a) that
          limit the remuneration included in wages based on the nature or
          location of the employment or the 

                                       1
<PAGE>
 
          services performed (such as the exception for agricultural labor in
          Code Section 3401(a)(2)).

     (b)  "Federal Income Tax Withholding Compensation" is wages within the
          meaning of Code Section 3401(a) for the purposes of income tax
          withholding at the source but determined without regard to any rules
          that limit the remuneration included in wages based on the nature or
          location of the employment or the services performed (such as the
          exception for agricultural labor in Code Section 3401(a)(2)).

     (c)  "415 Safe-Harbor Compensation" is wages, salaries, and fees for
          professional services and other amounts received (without regard to
          whether or not an amount is paid in cash) for personal services
          actually rendered in the course of employment with the Employer
          maintaining the Plan to the extent that the amounts are includible in
          gross income (including, but not limited to, commissions paid
          salesmen, compensation for services on the basis of a percentage of
          profits, commission on insurance premiums, tips, bonuses, fringe
          benefits and reimbursements or other expense allowances under a
          nonaccountable plan (as described in Code Section 1.62-2(c)), and
          excluding the following:

          (1)  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;

          (2)  Amounts realized from the exercise of a non-qualified 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;

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

          (4)  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 contract
               described in Code Section 403(b) (whether or not the
               contributions are actually excludable from the gross income of
               the Employee).

     If, in connection with the adoption of this or any other amendment, the
     definition of Compensation has been modified, then, for Plan Years prior to
     the Plan Year which includes the adoption date of such amendment,
     Compensation means compensation determined pursuant to the Plan then in
     effect.

     In addition, if specified in the Adoption Agreement, Compensation for all
     Plan purposes shall also include compensation which is not currently
     includible in the Participant's gross income by reason of the application
     of Code Sections 125, 402(e)(3), 402(h)(1)(B), or 403(b).

     For Plan Years beginning on or after January 1, 1989, and before January 1,
     1994, the annual compensation of each Participant taken into account for
     determining all benefits provided under

                                       2
<PAGE>
 
     the Plan for any Plan Year shall not exceed $200,000. This limitation shall
     be adjusted by the Secretary of the Treasury at the same time and in the
     same manner as under Code Section 415(d), except that the dollar increase
     in effect on January 1 of any calendar year is effective for Plan Years
     beginning in such calendar year and the first adjustment to the $200,000
     limitation is effective on January 1, 1990.

     Notwithstanding the above, for Plan Years beginning on or after January 1,
     1994, the Compensation of each Employee taken into account under the Plan
     shall not exceed the "OBRA '93 annual compensation limit". The "OBRA '93
     annual compensation limit" is $150,000, as adjusted by the Commissioner of
     the Internal Revenue Service for increases in the cost-of-living in
     accordance with Code Section 401(a)(17)(B). The cost-of-living adjustment
     in effect for a calendar year applies to any period, not exceeding 12
     months, over which Compensation is determined (determination period)
     beginning in such calendar year. If a determination period consists of
     fewer than 12 months, the OBRA '93 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.

     For Plan Years beginning on or after January 1, 1994, any reference in this
     Plan to the limitation under Code Section 401(a)(17) shall mean the "OBRA
     '93 annual compensation limit" set forth in this Section.

     In applying this limitation, the family group of a Highly Compensated
     Participant 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 the year, shall be treated as a single
     Participant, except that for this purpose Family Members shall include only
     the affected Participant's spouse and any lineal descendants who have not
     attained age nineteen (19) before the close of the year. If, as a result of
     the application of such rules, the adjusted limitation is exceeded, then
     (except for purposes of determining the portion of Compensation up to the
     integration level if this plan is integrated), the limitation shall be
     prorated among the affected individuals in proportion to each such
     individual's Compensation as determined under this Section prior to the
     application of this limitation.

     Compensation shall include only that compensation which is actually paid to
     the Participant during the determination period.

     For Plan Years beginning prior to January 1, 1989, a $200,000 limit
     (without regard to Family Member aggregation) shall apply only for Top
     Heavy Plan Years and shall not be adjusted.

1.10 "Contract" or "Policy" means any life insurance policy, retirement income
     policy, or annuity contract (group or individual) issued by the Insurer. In
     the event of any conflict between the terms of this Plan and the terms of
     any insurance contract purchased hereunder, the Plan provisions shall
     control.

1.11 "Deferred Compensation" means, with respect to any Participant, that
     portion of the Participant's total Compensation which has been contributed
     to the Plan in accordance with the Participant's deferral election pursuant
     to Section 11.2.

                                       3

1.12 "Early Retirement Date" means the date specified in the Adoption Agreement
     on which a Participant or Former Participant has satisfied the age and
     service requirements specified in the Adoption Agreement (Early Retirement
     Age). A Participant shall become fully Vested upon satisfying this
     requirement if still employed at his Early Retirement Age.

     A Former Participant who terminates employment after satisfying the service
     requirement for Early Retirement and who thereafter reaches the age
     requirement contained herein shall be entitled to receive his benefits
     under this Plan.

1.13 "Earned Income" means with respect to a Self-Employed Individual, the net
     earnings from self-employment in the trade or business with respect to
     which the Plan is established, for which the personal services of the
     individual are a material income-producing factor. Net earnings will be
     determined without regard to items not included in gross income and the
     deductions allocable to such items. Net earnings are reduced by
     contributions by the Employer to a qualified Plan to the extent deductible
     under Code Section 404. In addition, for Plan Years beginning after
     December 31, 1989, net earnings shall be determined with regard to the
     deduction allowed to the taxpayer by Code Section 164(f).

1.14 "Elective Contribution" means the Employer's contributions to the Plan that
     are made pursuant to the Participant's deferral election pursuant to
     Section 11.2, excluding any such amounts distributed as "excess annual
     additions" pursuant to Section 4.4. In addition, if selected in E3 of the
     Adoption Agreement, the Employer's matching contribution shall or shall not
     be considered an Elective Contribution for purposes of the Plan, as
     provided in Section 11.1(b). Elective Contributions shall be subject to the
     requirements of Sections 11.2(b) and 11.2(c) and shall further be required
     to satisfy the discrimination requirements of Regulation 1.401(k)-1(b)(3),
     the provisions of which are specifically incorporated herein by reference.

1.15 "Eligible Employee" means any Employee specified in D1 of the Adoption
     Agreement.

1.16 "Employee" means any person who is employed by the Employer, but excludes
     any person who is employed as an independent contractor. The term Employee
     shall also include Leased Employees as provided in Code Section 414(n) or
     (o).

     Except as provided in the Non-Standardized Adoption Agreement, all
     Employees of all entities which are an Affiliated Employer will be treated
     as employed by a single Employer.

1.17 "Employer" means the entity specified in the Adoption Agreement, any
     Participating Employer (as defined in Section 10.1) which shall adopt this
     Plan, any successor which shall maintain this Plan and any predecessor
     which has maintained this Plan.

1.18 "Excess Compensation" means, with respect to a Plan that is integrated with
     Social Security, a Participant's Compensation which is in excess of the
     amount set forth in the Adoption Agreement.

1.19 "Excess Contributions" means, with respect to a Plan Year, the excess of
     Elective Contributions and Qualified Non-Elective Contributions made on
     behalf of Highly Compensated Participants for the Plan Year over the
     maximum amount of such contributions permitted under Section 11.4(a).

                                       4
<PAGE>
 
1.20 "Excess Deferred Compensation" means, with respect to any taxable year of a
     Participant, the excess of the aggregate amount of such Participant's
     Deferred Compensation and the elective deferrals pursuant to Section
     11.2(f) actually made on behalf of such Participant for such taxable year,
     over the dollar limitation provided for in Code Section 402(g), which is
     incorporated herein by reference. Excess Deferred Compensation shall be
     treated as an "annual addition" pursuant to Section 4.4 when contributed to
     the Plan unless distributed to the affected Participant not later than the
     first April 15th following the close of the Participant's taxable year.

1.21 "Expected Year of Service" means an eligibility computation period of
     twelve (12) consecutive months during which an Eligible Employee is
     expected to complete at least 1,000 Hours of Service. The eligibility
     computation period shall be computed with reference to the date on which
     the Employee first performs an Hour of Service and the succeeding
     eligibility computation periods beginning on the anniversaries of that
     date. If an Employee who is not expected to complete 1,000 Hours of Service
     actually completes 1,000 Hours of Service during an applicable eligibility
     computation period, he shall be deemed to have become an Eligible Employee
     as of the first day of the eligibility computation period in which he first
     works 1,000 hours for the Employer.

1.22 "Family Member" means, with respect to an affected Participant, such
     Participant's spouse, and such Participant's lineal descendants and
     ascendants and their spouses, all as described in Code Section
     414(q)(6)(B).

1.23 "Fiduciary" means any person who (a) exercises any discretionary authority
     or discretionary control respecting management of the Plan or exercises any
     authority or control respecting management or disposition of its assets,
     (b) renders investment advice for a fee or other compensation, direct or
     indirect, with respect to any monies or other property of the Plan or has
     any authority or responsibility to do so, or (c) has any discretionary
     authority or discretionary responsibility in the administration of the
     Plan, including, but not limited to, the Trustee, the Employer and its
     representative body, and the Administrator.

1.24 "Fiscal Year" means the Employer's accounting year as specified in the
     Adoption Agreement.

1.25 "Forfeiture" means that portion of a Participant's Account that is not
     Vested, and occurs on the earlier of:

     (a)  the distribution of the entire Vested portion of a Participant's
          Account, or

     (b)  the last day of the Plan Year in which the Participant incurs five (5)
          consecutive 1-Year Breaks in Service.

     If a partial distribution of a Terminated Participant's total Vested
     interest is permitted, as specified in the Adoption Agreement, and if a
     Participant elects to have distributed less than his entire Vested
     interest, the part of his non-Vested interest that will be treated as an
     immediate Forfeiture is the total non-Vested portion multiplied by a
     fraction, the numerator of which is the amount of the distribution
     attributable to Employer contributions and the denominator of which is the
     total value of the Vested Employer-derived Participant's account balance.

                                       5
<PAGE>
 
     Furthermore, for purposes of paragraph (a) above, in the case of a
     Terminated Participant whose Vested benefit is zero, such Terminated
     Participant shall be deemed to have received a distribution of his Vested
     benefit upon his termination of employment. In addition, the term
     Forfeiture shall also include amounts deemed to be Forfeitures pursuant to
     any other provision of this Plan.

1.26 "Former Participant" means a person who has been a Participant, but who has
     ceased to be a Participant for any reason.

1.27 "414(s) Compensation" with respect to any Employee means his Compensation
     as defined in Section 1.9. However, for purposes of this Section, 414(s)
     Compensation shall or shall not be recognized as of an Employee's effective
     date of participation, as specified in the Adoption Agreement. If, in
     connection with the adoption of this or any other amendment, the definition
     of 414(s) Compensation has been modified, then, for Plan Years prior to the
     Plan Year which includes the adoption date of such amendment, 414(s)
     Compensation means compensation determined pursuant to the Plan then in
     effect.

     In addition, if specified in the Adoption Agreement, 414(s) Compensation
     shall also include compensation which is not currently includible in the
     Participant's gross income by reason of the application of Code Sections
     125, 402(e)(3), 402(h)(1)(B), or 403(b), plus Elective Contributions
     attributable to Deferred Compensation recharacterized as voluntary Employee
     contributions pursuant to 11.5(a).

1.28 "415 Compensation" means a Participant's Compensation as elected in the
     Adoption Agreement. However, regardless of any selection made in the
     Adoption Agreement, 415 Compensation shall exclude compensation which is
     not currently includible in the Participant's gross income by reason of the
     application of Code Sections 125, 402(e)(3), 402(h)(1)(B), or 403(b).

     415 Compensation is compensation that is used to determine the maximum
     permissible annual additions under Code Section 415 pursuant to Section 4.4
     of the Plan, the identities of a Highly Compensated Employee as described
     in Code Section 414(q) pursuant to Section 1.29 of the Plan and a Key
     Employee as described in Code Section 416(i)(1) pursuant to Section 1.36 of
     the Plan, and the required minimum allocations under a Top Heavy Plan as
     described in Code Section 416(c) pursuant to Section 4.3(f) of the Plan.

     For limitation years beginning after December 31, 1991, for purposes of
     applying the limitations of this Article, 415 Compensation for a limitation
     year is the compensation actually paid or made available during such
     limitation year.

     Notwithstanding the preceding sentence, 415 Compensation for a Participant
     in a defined contribution plan who is permanently and totally disabled (as
     defined in Code Section 22(e)(3)) 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
     permanently and totally disabled; such imputed 415 Compensation for the
     disabled Participant may be taken into account only if the contributions
     made on behalf of such Participant are nonforfeitable when made.

                                       6
<PAGE>
 
     If, in connection with the adoption of this or any other amendment, the
     definition of 415 Compensation has been modified, then, for Plan Years
     prior to the Plan Year which includes the adoption date of such amendment,
     415 Compensation means compensation determined pursuant to the Plan then in
     effect.

1.29 "Highly Compensated Employee" means an Employee described in Code Section
     414(q) and the Regulations thereunder and generally means an Employee who
     performed services for the Employer during the "determination year" and is
     in one or more of the following groups:

     (a)  Employees who at any time during the "determination year" or "look-
          back year" were "five percent owners" as defined in Section 1.36(c).
          If an Employee is, during a determination year or look-back 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 415 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.

     (b)  Employees who received 415 Compensation during the "look-back year"
          from the Employer in excess of $75,000.

     (c)  Employees who received 415 Compensation during the "look-back year"
          from the Employer in excess of $50,000 and were in the Top Paid Group
          of Employees for the Plan Year.

     (d)  Employees who during the "look-back year" were officers of the
          Employer (as that term is defined within the meaning of the
          Regulations under Code Section 416) and received 415 Compensation
          during the "look-back year" from the Employer greater than 50 percent
          of the limit in effect under Code Section 415(b)(1)(A) for any such
          Plan Year. The number of officers shall be limited to the lesser of
          (i) 50 employees; or (ii) the greater of 3 employees or 10 percent of
          all employees. If the Employer does not have at least one officer
          whose annual 415 Compensation is in excess of 50 percent of the Code
          Section 415(b)(1)(A) limit, then the highest paid officer of the
          Employer will be treated as a Highly Compensated Employee.

     (e)  Employees who are in the group consisting of the 100 Employees paid
          the greatest 415 Compensation during the "determination year" and are
          also described in (b), (c) or (d) above when these paragraphs are
          modified to substitute "determination year" for "look-back year".

                                       7
<PAGE>
 
     The "determination year" shall be the Plan Year for which testing is being
     performed, and the "look-back year" shall be the immediately preceding
     twelve-month period. However, if the Plan Year is a calendar year, or if
     another Plan of the Employer so provides, then the "look-back year" shall
     be the calendar year ending with or within the Plan Year for which testing
     is being performed, and the "determination year" (if applicable) shall be
     the period of time, if any, which extends beyond the "look-back year" and
     ends on the last day of the Plan Year for which testing is being performed
     (the "lag period"). With respect to this election, it shall be applied on a
     uniform and consistent basis to all plans, entities, and arrangements of
     the Employer.

     For purposes of this Section, the determination of 415 Compensation shall
     be made by including amounts that would otherwise be excluded from a
     Participant's gross income by reason of the application of Code Sections
     125, 402(e)(3), 402(h)(1)(B) and, in the case of Employer contributions
     made pursuant to a salary reduction agreement, Code Section 403(b).
     Additionally, the dollar threshold amounts specified in (b) and (c) above
     shall be adjusted at such time and in such manner as is provided in
     Regulations. In the case of such an adjustment, the dollar limits which
     shall be applied are those for the calendar year in which the
     "determination year" or "look back year" begins.

     In determining who is a Highly Compensated Employee, Employees who are non-
     resident aliens and who received no earned income (within the meaning of
     Code Section 911(d)) from the Employer constituting United States source
     income within the meaning of Code Section 861(a)(3) shall not be treated as
     Employees. Additionally, all Affiliated Employers shall be taken into
     account as a single employer and Leased Employees within the meaning of
     Code Sections 414(n)(2) and 414(o)(2) shall be considered Employees unless
     such Leased Employees are covered by a plan described in Code Section
     414(n)(5) and are not covered in any qualified plan maintained by the
     Employer. The exclusion of Leased Employees for this purpose shall be
     applied on a uniform and consistent basis for all of the Employer's
     retirement plans. In addition, Highly Compensated Former Employees shall be
     treated as Highly Compensated Employees without regard to whether they
     performed services during the "determination year".

1.30 "Highly Compensated Former Employee" means a former Employee who had a
     separation year prior to the "determination year" and was a Highly
     Compensated Employee in the year of separation from service or in any
     "determination year" after attaining age 55. Notwithstanding the foregoing,
     an Employee who separated from service prior to 1987 will be treated as a
     Highly Compensated Former Employee only if during the separation year (or
     year preceding the separation year) or any year after the Employee attains
     age 55 (or the last year ending before the Employee's 55th birthday), the
     Employee either received 415 Compensation in excess of $50,000 or was a
     "five percent owner". For purposes of this Section, "determination year",
     415 Compensation and "five percent owner" shall be determined in accordance
     with Section 1.29. Highly Compensated Former Employees shall be treated as
     Highly Compensated Employees. The method set forth in this Section for
     determining who is a "Highly Compensated Former Employee" shall be applied
     on a uniform and consistent basis for all purposes for which the Code
     Section 414(q) definition is applicable.

1.31 "Highly Compensated Participant" means any Highly Compensated Employee who
     is eligible to participate in the Plan.

                                       8
<PAGE>
 
1.32 "Hour of Service" means (1) each hour for which an Employee is directly or
     indirectly compensated or entitled to compensation by the Employer for the
     performance of duties during the applicable computation period; (2) each
     hour for which an Employee is directly or indirectly compensated or
     entitled to compensation by the Employer (irrespective of whether the
     employment relationship has terminated) for reasons other than performance
     of duties (such as vacation, holidays, sickness, jury duty, disability, 
     lay-off, military duty or leave of absence) during the applicable
     computation period; (3) each hour for which back pay is awarded or agreed
     to by the Employer without regard to mitigation of damages. These hours
     will be credited to the Employee for the computation period or periods to
     which the award or agreement pertains rather than the computation period in
     which the award agreement or payment is made. The same Hours of Service
     shall not be credited both under (1) or (2), as the case may be, and under
     (3).

     Notwithstanding the above, (i) no more than 501 Hours of Service are
     required to be credited to an Employee on account of any single continuous
     period during which the Employee performs no duties (whether or not such
     period occurs in a single computation period); (ii) an hour for which an
     Employee is directly or indirectly paid, or entitled to payment, on account
     of a period during which no duties are performed is not required to be
     credited to the Employee if such payment is made or due under a plan
     maintained solely for the purpose of complying with applicable worker's
     compensation, or unemployment compensation or disability insurance laws;
     and (iii) Hours of Service are not required to be credited for a payment
     which solely reimburses an Employee for medical or medically related
     expenses incurred by the Employee.

     For purposes of this Section, a payment shall be deemed to be made by or
     due from the Employer regardless of whether such payment is made by or due
     from the Employer directly, or indirectly through, among others, a trust
     fund, or insurer, to which the Employer contributes or pays premiums and
     regardless of whether contributions made or due to the trust fund, insurer,
     or other entity are for the benefit of particular Employees or are on
     behalf of a group of Employees in the aggregate.

     An Hour of Service must be counted for the purpose of determining a Year of
     Service, a year of participation for purposes of accrued benefits, a 1-Year
     Break in Service, and employment commencement date (or reemployment
     commencement date). The provisions of Department of Labor regulations
     2530.200b-2(b) and (c) are incorporated herein by reference.

     Hours of Service will be credited for employment with all Affiliated
     Employers and for any individual considered to be a Leased Employee
     pursuant to Code Sections 414(n) or 414(o) and the Regulations thereunder.

     Hours of Service will be determined on the basis of the method selected in
     the Adoption Agreement.

     Joint and Survivor Annuity will be the amount of benefit which can be
     purchased with the Participant's Vested interest in the Plan.

1.36 "Key Employee" means an Employee as defined in Code Section 416(i) and the
     Regulations thereunder. Generally, any Employee or former Employee (as well
     as each of his Beneficiaries) is considered a Key Employee if he, at any
     time during the Plan Year that contains the "Determination Date" or any of
     the preceding four (4) Plan Years, has been included in one of the
     following categories:

     (a)  an officer of the Employer (as that term is defined within the meaning
          of the Regulations under Code Section 416) having annual 415
          Compensation greater than 50 percent of the amount in effect under
          Code Section 415(b)(1)(A) for any such Plan Year.

     (b)  one of the ten Employees having annual 415 Compensation from the
          Employer for a Plan Year greater than the dollar limitation in effect
          under Code Section 415(c)(1)(A) for the calendar year in which such
          Plan Year ends and owning (or considered as owning within the meaning
          of Code Section 318) both more than one-half percent interest and the
          largest interests in the Employer.

     (c)  a "five percent owner" of the Employer. "Five percent owner" means any
          person who owns (or is considered as owning within the meaning of Code
          Section 318) more than five percent (5%) of the outstanding stock of
          the Employer or stock possessing more than five percent (5%) of the
          total combined voting power of all stock of the Employer or, in the
          case of an unincorporated business, any person who owns more than five
          percent (5%) of the capital or profits interest in the Employer. In
          determining percentage ownership hereunder, employers that would
          otherwise be aggregated under Code Sections 414(b), (c), (m) and (o)
          shall be treated as separate employers.

     (d)  a "one percent owner" of the Employer having an annual 415
          Compensation from the Employer of more than $150,000. "One percent
          owner" means any person who owns (or is considered as owning within
          the meaning of Code Section 318) more than one percent (1%) of the
          outstanding stock of the Employer or stock possessing more than one
          percent (1%) of the total combined voting power of all stock of the
          Employer or, in the case of an unincorporated business, any person who
          owns more than one percent (1%) of the capital or profits interest in
          the Employer. In determining percentage ownership hereunder, employers
          that would otherwise be aggregated under Code Sections 414(b), (c),
          (m) and (o) shall be treated as separate employers. However, in
          determining whether an individual has 415 Compensation of more than
          $150,000, 415 Compensation from each employer required to be
          aggregated under Code Sections 414(b), (c), (m) and (o) shall be taken
          into account.

                                       10
<PAGE>
 
     For purposes of this Section, the determination of 415 Compensation shall
     be made by including amounts that would otherwise be excluded from a
     Participant's gross income by reason of the application of Code Sections
     125, 402(e)(3), 402(h)(1)(B) and, in the case of Employer contributions

     (or for the recipient and related persons determined in accordance with
     Code Section 414(n)(6)) on a substantially full time basis for a period of
     at least one year, and such services are of a type historically performed
     by employees in the business field of the recipient employer. Contributions
     or benefits provided a leased employee by the leasing organization which
     are attributable to services performed for the recipient employer shall be
     treated as provided by the recipient employer.

     A leased employee shall not be considered an Employee of the recipient if:
     (i) such employee is covered by a money purchase pension plan providing:
     (1) a nonintegrated employer contribution rate of at least 10 percent of
     415 Compensation, as defined in Code Section 415(c)(3), but including
     amounts contributed pursuant to a salary reduction agreement which are
     excludable from the employee's gross income under Code Sections 125,
     402(a)(8), 402(h), or 403(b), (2) immediate participation, and (3) full and
     immediate vesting; and (ii) leased employees do not constitute more than 20
     percent of the recipient's nonhighly compensated workforce.

1.39 "Net Profit" means with respect to any Fiscal Year the Employer's net

     Non-Elective Contribution for purposes of the Plan.

1.45 "1-Year Break in Service" means the applicable computation period during
     which an Employee has not completed more than 500 Hours of Service with the
     Employer. Further, solely for the purpose of determining whether a

     be recognized for "authorized leaves of absence" and "maternity and
     paternity leaves of absence."

     "Authorized leave of absence" means an unpaid, temporary cessation from
     active employment with the Employer pursuant to an established
     nondiscriminatory policy, whether occasioned by illness, military service,

     A "maternity or paternity leave of absence" means, for Plan Years beginning
     after December 31, 1984, an absence from work for any period by reason of
     the Employee's pregnancy, birth of the Employee's child, placement of a
     child with the Employee in connection with the adoption of such child, or
     any absence for the purpose of caring for such child for a period
     immediately following such birth or placement. For this purpose, Hours of
     Service shall be credited for the computation period in which the absence
     from work begins, only if credit therefore is necessary to prevent the
     Employee from incurring a 1-Year Break in Service, or, in any other case,
     in the immediately following computation period. The Hours of Service
     credited for a "maternity or paternity leave of absence" shall be those
     which would normally have been credited but for such absence, or, in any
     case in which the Administrator is unable to determine such hours normally

     Elective Contributions and Employer's matching contributions (pursuant to
     Section 1.40), in the case of a 401(k) Profit Sharing Plan. In the case of
     a 401(k) Profit Sharing Plan, a separate accounting record shall be
     maintained with respect to that portion of the Participant's Account
     attributable to Non-Elective Contributions and Employer's matching
     contributions.

<PAGE>
 
     911(d)(2)) from the Employer constituting United States source income

     In addition, if 90 percent or more of the Employees of the Employer are
     covered under agreements the Secretary of Labor finds to be collective
     bargaining agreements between Employee representatives and the Employer,
     and the Plan covers only Employees who are not covered under such
     agreements, then Employees covered by such agreements shall be excluded
     from both the total number of active Employees as well as from the
     identification of particular Employees in the Top Paid Group.

     The foregoing exclusions set forth in this Section shall be applied on a

<PAGE>
 
     For purposes of eligibility for participation, the initial computation
     period shall begin with the date on which the Employee first performs an
     Hour of Service (employment commencement date). The computation period
     beginning after a 1-Year Break in Service shall be measured from the date
     on which an Employee again performs an Hour of Service. The succeeding
     computation periods shall begin with the first anniversary of the
     Employee's employment commencement date. However, if one (1) Year of
     Service or less is required as a condition of eligibility, then after the
     initial eligibility computation period, the eligibility computation period
     shall, if elected in the Adoption Agreement, either begin with the
     anniversary(s) of the Employee's employment commencement date or shift to
     the current Plan Year which includes the anniversary of the date on which
     the Employee first performed an Hour of Service. If the initial eligibility
     computation period shifts to the Plan Year, then an Employee who is
     credited with 1,000 Hours of Service in both the initial eligibility
     computation period and the first Plan Year which commences prior to the
     first anniversary of the Employee's initial eligibility computation period
     will be credited with two Years of Service for purposes of eligibility to
     participate.

     For vesting purposes, and all other purposes not specifically addressed in
     this Section, the computation period shall be, as elected in the Adoption
     Agreement, either (i) the Plan Year or (ii) an Employee's employment
     commencement date or re-employment commencement date and anniversaries of
     an Employee's employment commencement date or re-employment commencement
     dates, as applicable. Such vesting computation periods shall include
     periods prior to the Effective Date of the Plan unless specifically
     excluded pursuant to the Adoption Agreement.

     Years of Service and breaks in service will be measured on the same
     computation period.

     Years of Service with any predecessor Employer which maintained this Plan
     shall be recognized. Years of Service with any other predecessor Employer
     shall be recognized as specified in the Adoption Agreement.

     Years of Service with any Affiliated Employer shall be recognized.

                    TOP HEAVY PROVISIONS AND ADMINISTRATION

2.1   TOP HEAVY PLAN REQUIREMENTS

      For any Top Heavy Plan Year, the Plan shall provide the special vesting
      requirements of Code Section 416(b) pursuant to Section 6.4 of the Plan
      and the special minimum allocation requirements of Code Section 416(c)
      pursuant to Section 4.3(f) of the Plan.

2.2   DETERMINATION OF TOP HEAVY STATUS

      (a) This Plan shall be a Top Heavy Plan for any Plan Year beginning after
          December 31, 1983, in which, as of the Determination Date, (1) the
          Present Value of Accrued Benefits of Key Employees and (2) the sum of
          the Aggregate Accounts of Key Employees under this Plan and all plans
          of an Aggregation Group, exceeds sixty percent (60%) of the Present
          Value of Accrued Benefits and the Aggregate Accounts of all Key and
          Non-Key Employees under this Plan and all plans of an Aggregation
          Group.

          If any Participant is a Non-Key Employee for any Plan Year, but such
          Participant was a Key Employee for any prior Plan Year, such
          Participant's Present Value of Accrued Benefit and/or Aggregate
          Account balance shall not be taken into account for purposes of
          determining whether this Plan is a Top Heavy or Super Top Heavy Plan
          (or whether any Aggregation Group which includes this Plan is a Top
          Heavy Group). In addition, if a Participant or Former Participant has
          not performed any services for any Employer maintaining the Plan at
          any time during the five year period ending on the Determination Date,
          any accrued benefit for such Participant or Former Participant shall
          not be taken into account for the purposes of determining whether this
          Plan is a Top Heavy or Super Top Heavy Plan.

      (b) This Plan shall be a Super Top Heavy Plan for any Plan Year beginning
          after December 31, 1983, in which, as of the Determination Date, (1)
          the Present Value of Accrued Benefits of Key Employees and (2) the sum
          of the Aggregate Accounts of Key Employees under this Plan and all
          plans of an Aggregation Group, exceeds ninety percent (90%) of the
          Present Value of Accrued Benefits and the Aggregate Accounts of all
          Key and Non-Key Employees under this Plan and all plans of an
          Aggregation Group.

      (c) Aggregate Account: A Participant's Aggregate Account as of the
          Determination Date is the sum of:

          (1)   his Participant's Combined Account balance as of the most recent
                valuation occurring within a twelve (12) month period ending on
                the Determination Date;

          (2)   for a Profit Sharing Plan, an adjustment for any contributions
                due as of the Determination Date. Such adjustment shall be the
                amount of any contributions actually made after the valuation
                date but before the Determination Date, except for the first
                Plan Year when such adjustment shall also reflect the 

                                       17
<PAGE>
 
                amount of any contributions made after the Determination Date
                that are allocated as of a date in that first Plan Year;

          (3)   for a Money Purchase Plan, contributions that would be allocated
                as of a date not later than the Determination Date, even though
                those amounts are not yet made or required to be made.

          (4)   any Plan distributions made within the Plan Year that includes
                the Determination Date or within the four (4) preceding Plan
                Years. However, in the case of distributions made after the
                valuation date and prior to the Determination Date, such
                distributions are not included as distributions for top heavy
                purposes to the extent that such distributions are already
                included in the Participant's Aggregate Account balance as of
                the valuation date. In the case of a distribution of an annuity
                Contract, the amount of such distribution is deemed to be the
                current actuarial value of the Contract, determined on the date
                of the distribution. Notwithstanding anything herein to the
                contrary, all distributions, including distributions made prior
                to January 1, 1984, and distributions under a terminated plan
                which if it had not been terminated would have been required to
                be included in an Aggregation Group, will be counted. Further,
                distributions from the Plan (including the cash value of life
                insurance policies) of a Participant's account balance because
                of death shall be treated as a distribution for the purpose of
                this paragraph.

          (5)   any Employee contributions, whether voluntary or mandatory.
                However, amounts attributable to tax deductible qualified
                voluntary employee contributions shall not be considered to be a
                part of the Participant's Aggregate Account balance.

          (6)   with respect to unrelated rollovers and plan-to-plan transfers
                (ones which are both initiated by the Employee and made from a
                plan maintained by one employer to a plan maintained by another
                employer), if this Plan provides the rollovers or plan-to-plan
                transfers, it shall always consider such rollovers or plan-to-
                plan transfers as a distribution for the purposes of this
                Section. If this Plan is the plan accepting such rollovers or
                plan-to-plan transfers, it shall not consider such rollovers or
                plan-to-plan transfers accepted after December 31, 1983 as part
                of the Participant's Aggregate Account balance. However,
                rollovers or plan-to-plan transfers accepted prior to January 1,
                1984 shall be considered as part of the Participant's Aggregate
                Account balance.

          (7)   with respect to related rollovers and plan-to-plan transfers
                (ones either not initiated by the Employee or made to a plan
                maintained by the same employer), if this Plan provides the
                rollover or plan-to-plan transfer, it shall not be counted as a
                distribution for purposes of this Section. If this Plan is the
                plan accepting such rollover or plan-to-plan transfer, it shall
                consider such rollover or plan-to-plan transfer as part of the
                Participant's Aggregate Account balance, irrespective of the
                date on which such rollover or plan-to-plan transfer is
                accepted.

          (8)   For the purposes of determining whether two employers are to be
                treated as the same employer in 2.2(c)(6) and 2.2(c)(7) above,
                all employers aggregated under Code Sections 414(b), (c), (m)
                and (o) are treated as the same employer.

      (d) "Aggregation Group" means either a Required Aggregation Group or a
          Permissive Aggregation Group as hereinafter determined.

          (1)   Required Aggregation Group: In determining a Required
                Aggregation Group hereunder, each qualified plan of the
                Employer, including any Simplified Employee Pension Plan, in
                which a Key Employee is a participant in the Plan Year
                containing the Determination Date or any of the four preceding
                Plan Years, and each other qualified plan of the Employer which
                enables any qualified plan in which a Key Employee participates
                to meet the requirements of Code Sections 401(a)(4) or 410, will
                be required to be aggregated. Such group shall be known as a
                Required Aggregation Group.

                In the case of a Required Aggregation Group, each plan in the
                group will be considered a Top Heavy Plan if the Required
                Aggregation Group is a Top Heavy Group. No plan in the Required
                Aggregation Group will be considered a Top Heavy Plan if the
                Required Aggregation Group is not a Top Heavy Group.

          (2)   Permissive Aggregation Group: The Employer may also include any
                other plan of the Employer, including any Simplified Employee
                Pension Plan, not required to be included in the Required
                Aggregation Group, provided the resulting group, taken as a
                whole, would continue to satisfy the provisions of Code Sections
                401(a)(4) and 410. Such group shall be known as a Permissive
                Aggregation Group.

                In the case of a Permissive Aggregation Group, only a plan that
                is part of the Required Aggregation Group will be considered a
                Top Heavy Plan if the Permissive Aggregation Group is a Top
                Heavy Group. No plan in the Permissive Aggregation Group will be
                considered a Top Heavy Plan if the Permissive Aggregation Group
                is not a Top Heavy Group.

          (3)   Only those plans of the Employer in which the Determination
                Dates fall within the same calendar year shall be aggregated in
                order to determine whether such plans are Top Heavy Plans.

          (4)   An Aggregation Group shall include any terminated plan of the
                Employer if it was maintained within the last five (5) years
                ending on the Determination Date.

      (e) "Determination Date" means (a) the last day of the preceding Plan
          Year, or (b) in the case of the first Plan Year, the last day of such
          Plan Year.

                                       19

      (f) Present Value of Accrued Benefit: In the case of a defined benefit
          plan, the Present Value of Accrued Benefit for a Participant other
          than a Key Employee shall be as determined using the single accrual
          method used for all plans of the Employer and Affiliated Employers, or
          if no such single method exists, using a method which results in
          benefits accruing not more rapidly than the slowest accrual rate
          permitted under Code Section 411(b)(1)(C). The determination of the
          Present Value of Accrued Benefit shall be determined as of the most
          recent valuation date that falls within or ends with the 12-month
          period ending on the Determination Date, except as provided in Code
          Section 416 and the Regulations thereunder for the first and second
          plan years of a defined benefit plan.

          However, any such determination must include present value of accrued
          benefit attributable to any Plan distributions referred to in Section
          2.2(c)(4) above, any Employee contributions referred to in Section
          2.2(c)(5) above or any related or unrelated rollovers referred to in
          Sections 2.2(c)(6) and 2.2(c)(7) above.

      (g) "Top Heavy Group" means an Aggregation Group in which, as of the
          Determination Date, the sum of:

          (1)   the Present Value of Accrued Benefits of Key Employees under all
                defined benefit plans included in the group, and

          (2)   the Aggregate Accounts of Key Employees under all defined
                contribution plans included in the group,

                exceeds sixty percent (60%) of a similar sum determined for all
          Participants.

      (h) "Top Heavy Ratio" means:

          (1)   If the Employer maintains one or more defined contribution plans
                (including any simplified employee pension plan) and the
                Employer has not maintained any defined benefit plan which
                during the 5-year period ending on the "determination date(s)"
                has or has had accrued benefits, the Top Heavy Ratio for this
                Plan alone or for the Required or Permissive Aggregation Group
                as appropriate is a fraction, the numerator of which is the sum
                of the account balances of all Key Employees as of the
                "Determination Date(s)" (including any part of any account
                balance distributed in the 5-year period ending on the
                "Determination Date(s)"), and the denominator of which is the
                sum of all account balances (including any part of any account
                balance distributed in the 5-year period ending on the
                "Determination Date(s)"), both computed in accordance with Code
                Section 416 and the Regulations thereunder. Both the numerator
                and denominator of the Top Heavy Ratio are increased to reflect
                any contribution not actually made as of the "Determination
                Date", but which is required to be taken into account on that
                date under Code Section 416 and the Regulations thereunder.

                                       20
<PAGE>
 
          (2)   If the Employer maintains one or more defined contribution plans
                (including any simplified employee pension plan) and the
                Employer maintains or has maintained one or more defined benefit
                plans which during the 5-year period ending on the
                "Determination Date(s)" has or has had accrued benefits, the Top
                Heavy Ratio for any Required or Permissive Aggregation Group as
                appropriate is a fraction, the numerator of which is the sum of
                the account balances under the aggregated defined contribution
                plan or plans for all Key Employees, determined in accordance
                with (1) above, and the Present Value of Accrued Benefits under
                the aggregated defined benefit plan or plans for all Key
                Employees as of the "Determination Date(s)", and the denominator
                of which is the sum of the account balances under the aggregated
                defined contribution plan or plans for all Participants,
                determined in accordance with (1) above, and the Present Value
                of Accrued Benefits under the defined benefit plan or plans for
                all Participants as of the "Determination Date(s)", all
                determined in accordance with Code Section 416 and the
                Regulations thereunder. The accrued benefits under a defined
                benefit plan in both the numerator and denominator of the Top
                Heavy Ratio are increased for any distribution of an accrued
                benefit made in the 5-year period ending on the "Determination
                Date."

          (3)   For purposes of (1) and (2) above the value of account balances
                will be determined as of the most recent valuation date that
                falls within or ends with the 12-month period ending on the
                "Determination Date," except as provided in Code Section 416 and
                the Regulations thereunder for the first and second plan years
                of a defined benefit plan. The account balances and accrued
                benefits of a Participant (i) who is not a Key Employee but who
                was a Key Employee in a prior year, or (ii) who has not been
                credited with at least one (1) Hour of Service with any Employer
                maintaining the Plan at any time during the 5-year period ending
                on the "Determination Date" will be disregarded. The
                determination of the Top Heavy Ratio, and the extent to which
                distributions, rollovers, and transfers are taken into account
                will be made in accordance with Code Section 416 and the
                Regulations thereunder. Deductible Employee contributions will
                not be taken into account for purposes of computing the Top
                Heavy Ratio. When aggregating plans the value of account
                balances and accrued benefits will be calculated with reference
                to the "Determination Dates" that fall within the same calendar
                year.

                The accrued benefit of a Participant other than a Key Employee
                shall be determined under (a) the method, if any, that uniformly
                applies for accrual purposes under all defined benefit plans
                maintained by the Employer, or (b) if there is no such method,
                as if such benefit accrued not more rapidly than the slowed
                accrual rate permitted under the fractional rule of Code Section
                411(b)(1)(C).

                (i)  The Administrator shall determine whether this Plan is a
                     Top Heavy Plan on the Anniversary Date specified in the
                     Adoption Agreement. Such determination of the top heavy
                     ratio shall be in accordance with Code Section 416 and the
                     Regulations thereunder.

2.3   POWERS AND RESPONSIBILITIES OF THE EMPLOYER

      (a) The Employer shall be empowered to appoint and remove the Trustee and
          the Administrator from time to time as it deems necessary for the
          proper administration of the Plan to assure that the Plan is being
          operated for the exclusive benefit of the Participants and their
          Beneficiaries in accordance with the terms of the Plan, the Code, and
          the Act.

      (b) The Employer shall establish a "funding policy and method," i.e., it
          shall determine whether the Plan has a short run need for liquidity
          (e.g., to pay benefits) or whether liquidity is a long run goal and
          investment growth (and stability of same) is a more current need, or
          shall appoint a qualified person to do so. The Employer or its
          delegate shall communicate such needs and goals to the Trustee, who
          shall coordinate such Plan needs with its investment policy. The
          communication of such a "funding policy and method" shall not,
          however, constitute a directive to the Trustee as to investment of the
          Trust Funds. Such "funding policy and method" shall be consistent with
          the objectives of this Plan and with the requirements of Title I of
          the Act.

      (c) The Employer may, in its discretion, appoint an Investment Manager to
          manage all or a designated portion of the assets of the Plan. In such
          event, the Trustee shall follow the directive of the Investment
          Manager in investing the assets of the Plan managed by the Investment
          Manager.

      (d) The Employer shall periodically review the performance of any
          Fiduciary or other person to whom duties have been delegated or
          allocated by it under the provisions of this Plan or pursuant to
          procedures established hereunder. This requirement may be satisfied by
          formal periodic review by the Employer or by a qualified person
          specifically designated by the Employer, through day-to-day conduct
          and evaluation, or through other appropriate ways.

2.4   DESIGNATION OF ADMINISTRATIVE AUTHORITY

      The Employer shall appoint one or more Administrators. Any person,
      including, but not limited to, the Employees of the Employer, shall be
      eligible to serve as an Administrator. Any person so appointed shall
      signify his acceptance by filing written acceptance with the Employer. An
      Administrator may resign by delivering his written resignation to the
      Employer or be removed by the Employer by delivery of written notice of
      removal, to take effect at a date specified therein, or upon delivery to
      the Administrator if no date is specified.

      The Employer, upon the resignation or removal of an Administrator, shall
      promptly designate in writing a successor to this position. If the
      Employer does not appoint an Administrator, the Employer will function as
      the Administrator.

                                       22
<PAGE>
 
2.5   ALLOCATION AND DELEGATION OF RESPONSIBILITIES

      If more than one person is appointed as Administrator, the
      responsibilities of each Administrator may be specified by the Employer
      and accepted in writing by each Administrator. In the event that no such
      delegation is made by the Employer, the Administrators may allocate the
      responsibilities among themselves, in which event the Administrators shall
      notify the Employer and the Trustee in writing of such action and specify
      the responsibilities of each Administrator. The Trustee thereafter shall
      accept and rely upon any documents executed by the appropriate
      Administrator until such time as the Employer or the Administrators file
      with the Trustee a written revocation of such designation.

2.6   POWERS AND DUTIES OF THE ADMINISTRATOR

      The primary responsibility of the Administrator is to administer the Plan
      for the exclusive benefit of the Participants and their Beneficiaries,
      subject to the specific terms of the Plan. The Administrator shall
      administer the Plan in accordance with its terms and shall have the power
      and discretion to construe the terms of the Plan and determine all
      questions arising in connection with the administration, interpretation,
      and application of the Plan. Any such determination by the Administrator
      shall be conclusive and binding upon all persons. The Administrator may
      establish procedures, correct any defect, supply any information, or
      reconcile any inconsistency in such manner and to such extent as shall be
      deemed necessary or advisable to carry out the purpose of the Plan;
      provided, however, that any procedure, discretionary act, interpretation
      or construction shall be done in a nondiscriminatory manner based upon
      uniform principles consistently applied and shall be consistent with the
      intent that the Plan shall continue to be deemed a qualified plan under
      the terms of Code Section 401(a), and shall comply with the terms of the
      Act and all regulations issued pursuant thereto. The Administrator shall
      have all powers necessary or appropriate to accomplish his duties under
      this Plan.

      The Administrator shall be charged with the duties of the general
      administration of the Plan, including, but not limited to, the following:

      (a) the discretion to determine all questions relating to the eligibility
          of Employees to participate or remain a Participant hereunder and to
          receive benefits under the Plan;

      (b) to compute, certify, and direct the Trustee with respect to the amount
          and the kind of benefits to which any Participant shall be entitled
          hereunder;

      (c) to authorize and direct the Trustee with respect to all
          nondiscretionary or otherwise directed disbursements from the Trust
          Fund;

      (d) to maintain all necessary records for the administration of the Plan;

      (e) to interpret the provisions of the Plan and to make and publish such
          rules for regulation of the Plan as are consistent with the terms
          hereof;

                                       23
<PAGE>
 
      (f) to determine the size and type of any Contract to be purchased from
          any Insurer, and to designate the Insurer from which such Contract
          shall be purchased;

      (g) to compute and certify to the Employer and to the Trustee from time to
          time the sums of money necessary or desirable to be contributed to the
          Trust Fund;

      (h) to consult with the Employer and the Trustee regarding the short and
          long-term liquidity needs of the Plan in order that the Trustee can
          exercise any investment discretion in a manner designed to accomplish
          specific objectives;

      (i) to prepare and distribute to Employees a procedure for notifying

          Survivor Annuities and Pre-Retirement Survivor Annuities if required
          by the Code and Regulations thereunder;

      (j) to assist any Participant regarding his rights, benefits, or elections
          available under the Plan.

2.13  CLAIMS REVIEW PROCEDURE

      Any Employee, former Employee, or Beneficiary of either, who has been
      denied a benefit by a decision of the Administrator pursuant to Section
      2.12 shall be entitled to request the Administrator to give further
      consideration to his claim by filing with the Administrator a written
      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 Administrator no later than 60 days after receipt of the
      written notification provided for in Section 2.12. The 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 expense 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
      Administrator) the claimant or his representative shall have an
      opportunity to review all documents in the possession of the Administrator
      which are pertinent to the claim at issue and its disallowance. Either the
      claimant or the 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 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.

                                  ELIGIBILITY

3.1   CONDITIONS OF ELIGIBILITY

      Any Eligible Employee shall be eligible to participate hereunder on the
      date he has satisfied the requirements specified in the Adoption
      Agreement.

3.2   EFFECTIVE DATE OF PARTICIPATION

      An Eligible Employee who has become eligible to be a Participant shall
      become a Participant effective as of the day specified in the Adoption
      Agreement.

      In the event an Employee who has satisfied the Plan's eligibility
      requirements and would otherwise have become a Participant shall go from a
      classification of a noneligible Employee to an Eligible Employee, such
      Employee shall become a Participant as of the date he becomes an Eligible
      Employee.

      In the event an Employee who has satisfied the Plan's eligibility
      requirements and would otherwise become a Participant shall go from a
      classification of an Eligible Employee to a noneligible Employee and
      becomes ineligible to participate and has not incurred a 1-Year Break in
      Service, such Employee shall participate in the Plan as of the date he
      returns to an eligible class of Employees. If such Employee does incur a
      1-Year Break in Service, eligibility will be determined under the Break in
      Service rules of the Plan.

      In the event that the Plan is a TRA '86 amendment and restatement,
      effective with the first day of the 1989 Plan Year, an Employee's
      eligibility to make Elective Contributions shall not be conditioned upon
      the completion of more than one (1) Year of Service. An Employee's
      eligibility to receive any qualified matching contributions, matching
      contributions, Qualified Non-Elective Contributions or Non-Elective
      Contributions shall not be conditioned upon the completion of more than
      two (2) Years of Service. No contributions or benefits (other than
      matching contributions or qualified matching contributions) may be
      conditioned upon Elective Contributions.

3.3   DETERMINATION OF ELIGIBILITY

      The Administrator shall determine the eligibility of each Employee for
      participation in the Plan based upon information furnished by the
      Employer. Such determination shall be conclusive and binding upon all
      persons, as long as the same is made pursuant to the Plan and the Act.
      Such determination shall be subject to review per Section 2.13.

                                       27
<PAGE>
 
3.4   TERMINATION OF ELIGIBILITY

      In the event a Participant shall go from a classification of an Eligible
      Employee to an ineligible Employee, such Former Participant shall continue
      to vest in his interest in the Plan for each Year of Service completed
      while a noneligible Employee, until such time as his Participant's Account
      shall be forfeited or distributed pursuant to the terms of the Plan.
      Additionally, his interest in the Plan shall continue to share in the
      earnings of the Trust Fund.


3.5   OMISSION OF ELIGIBLE EMPLOYEE

      If, in any Plan Year, any Employee who should be included as a Participant
      in the Plan is erroneously omitted and discovery of such omission is not
      made until after a contribution by his Employer for the year has been
      made, the Employer shall make a subsequent contribution, if necessary
      after the application of Section 4.3(e), so that the omitted Employee
      receives a total amount which the said Employee would have received had he
      not been omitted. Such contribution shall be made regardless of whether or
      not it is deductible in whole or in part in any taxable year under
      applicable provisions of the Code.

3.6   INCLUSION OF INELIGIBLE EMPLOYEE

      If, in any Plan Year, any person who should not have been included as a
      Participant in the Plan is erroneously included and discovery of such
      incorrect inclusion is not made until after a contribution for the year
      has been made, the Employer shall not be entitled to recover the
      contribution made with respect to the ineligible person regardless of
      whether or not a deduction is allowable with respect to such contribution.
      In such event, the amount contributed with respect to the ineligible
      person shall constitute a Forfeiture for the Plan Year in which the
      discovery is made.

3.7   ELECTION NOT TO PARTICIPATE

      An Employee may, subject to the approval of the Employer, elect
      voluntarily not to participate in the Plan. The election not to
      participate must be communicated to the Employer, in writing, at least
      thirty (30) days before the beginning of a Plan Year. For Standardized
      Plans, a Participant or an Eligible Employee may not elect not to
      participate. Furthermore, the foregoing election not to participate shall
      not be available with respect to partners in a partnership.

3.8   CONTROL OF ENTITIES BY OWNER-EMPLOYEE

      (a) If this Plan provides contributions or benefits for one or more Owner-
          Employees who control both the business for which this Plan is
          established and one or more other entities, this Plan and the plan
          established for other trades or businesses must, when looked at as a
          single Plan, satisfy Code Sections 401(a) and (d) for the Employees of
          this and all other entities.

                                       28
<PAGE>
 
      (b) If the Plan provides contributions or benefits for one or more Owner-
          Employees who control one or more other trades or businesses, the
          employees of the other trades or businesses must be included in a plan
          which satisfies Code Sections 401(a) and (d) and which provides
          contributions and benefits not less favorable than provided for Owner-
          Employees under this Plan.

      (c) If an individual is covered as an Owner-Employee under the plans of
          two or more trades or businesses which are not controlled and the
          individual controls a trade or business, then the benefits or
          contributions of the employees under the plan of the trades or
          businesses which are controlled must be as favorable as those provided
          for him under the most favorable plan of the trade or business which
          is not controlled.

      (d) For purposes of the preceding paragraphs, an Owner-Employee, or two or
          more Owner-Employees, will be considered to control an entity if the
          Owner-Employee, or two or more Owner-Employees together:

          (1)   own the entire interest in an unincorporated entity, or

          (2)   in the case of a partnership, own more than 50 percent of either
                the capital interest or the profits interest in the partnership.

      (e) For purposes of the preceding sentence, an Owner-Employee, or two or
          more Owner-Employees shall be treated as owning any interest in a
          partnership which is owned, directly or indirectly, by a partnership
          which such Owner-Employee, or such two or more Owner-Employees, are
          considered to control within the meaning of the preceding sentence.

                          CONTRIBUTION AND ALLOCATION


4.1   FORMULA FOR DETERMINING EMPLOYER'S CONTRIBUTION

      (a) For a Money Purchase Plan -

          (1)   The Employer shall make contributions over such period of years
                as the Employer may determine on the following basis. On behalf
                of each Participant eligible to share in allocations, for each
                year of his participation in this Plan, the Employer shall
                contribute the amount specified in the Adoption Agreement. All
                contributions by the Employer shall be made in cash or in such
                property as is acceptable to the Trustee. The Employer shall be
                required to obtain a waiver from the Internal Revenue Service
                for any Plan Year in which it is unable to make the full
                required contribution to the Plan. In the event a waiver is
                obtained, this Plan shall be deemed to be an individually
                designed plan.

          (2)   For any Plan Year beginning prior to January 1, 1990, and if
                elected in the non-standardized Adoption Agreement for any Plan
                Year beginning on or after January 1, 1990, the Employer shall
                not contribute on behalf of a Participant who performs less than
                a Year of Service during any Plan Year, unless there is a Short
                Plan Year or a contribution is required pursuant to 4.3(h).

          (3)   Notwithstanding the foregoing, the Employer's contribution for
                any Fiscal Year shall not exceed the maximum amount allowable as
                a deduction to the Employer under the provisions of Code Section
                404. However, to the extent necessary to provide the top heavy
                minimum allocations, the Employer shall make a contribution even
                if it exceeds the amount which is deductible under Code Section
                404.

      (b) For a Profit Sharing Plan -

          (1)   For each Plan Year, the Employer shall contribute to the Plan
                such amount as specified by the Employer in the Adoption
                Agreement. Notwithstanding the foregoing, however, the
                Employer's contribution for any Fiscal Year shall not exceed the
                maximum amount allowable as a deduction to the Employer under
                the provisions of Code Section 404. All contributions by the
                Employer shall be made in cash or in such property as is
                acceptable to the Trustee.

          (2)   Except, however, to the extent necessary to provide the top
                heavy minimum allocations, the Employer shall make a
                contribution even if it exceeds current or accumulated Net
                Profit or the amount which is deductible under Code Section 404.

                                       30

4.2   TIME OF PAYMENT OF EMPLOYER'S CONTRIBUTION

      The Employer shall generally pay to the Trustee its contribution to the
      Plan for each Plan Year within the time prescribed by law, including
      extensions of time, for the filing of the Employer's federal income tax
      return for the Fiscal Year.

4.3   ALLOCATION OF CONTRIBUTION, FORFEITURES AND EARNINGS

      (a) The Administrator shall establish and maintain an account in the name
          of each Participant to which the Administrator shall credit as of each
          Anniversary Date, or other valuation date, all amounts allocated to
          each such Participant as set forth herein.

      (b) The Employer shall provide the Administrator with all information
          required by the Administrator to make a proper allocation of the
          Employer's contributions for each Plan Year. Within a reasonable
          period of time after the date of receipt by the Administrator of such
          information, the Administrator shall allocate such contribution as
          follows:

          (1)   For a Money Purchase Plan:

                (i)  The Employer's Contribution shall be allocated to each
                     Participant's Combined Account in the manner set forth in
                     Section 4.1 herein and as specified in Section E2 of the
                     Adoption Agreement.

          (2)   For an Integrated Profit Sharing Plan:

                (i)  The Employer's contribution shall be allocated to each
                     Participant's Account, except as provided in Section
                     4.3(f), in a dollar amount equal to 5.7% of the sum of each
                     Participant's total Compensation plus Excess Compensation.
                     If the Employer does not contribute such amount for all
                     Participants, each Participant will be allocated a share of
                     the contribution in the same proportion that his total
                     Compensation plus his total Excess Compensation for the
                     Plan Year bears to the total Compensation plus the total
                     Excess Compensation of all Participants for that year.

                     Regardless of the preceding, 4.3% shall be substituted for
                     5.7% above if Excess Compensation is based on more than 20%
                     and less than or equal to 80% of the Taxable Wage Base. If
                     Excess Compensation is based on less than 100% and more
                     than 80% of the Taxable Wage Base, then 5.4% shall be
                     substituted for 5.7% above.

                                       31
<PAGE>
 
                (ii) The balance of the Employer's contribution over the amount
                     allocated above, if any, shall be allocated to each
                     Participant's Combined Account in the same proportion that
                     his total Compensation for the Year bears to the total
                     Compensation of all Participants for such year.

                (iii)Except, however, for any Plan Year beginning prior to
                     January 1, 1990, and if elected in the non-standardized
                     Adoption Agreement for any Plan Year beginning on or after
                     January 1, 1990, a Participant who performs less than a
                     Year of Service during any Plan Year shall not share in the
                     Employer's contribution for that year, unless there is a
                     Short Plan Year or a contribution is required pursuant to
                     Section 4.3(h).

          (3)   For a Non-Integrated Profit Sharing Plan:

                (i)  The Employer's contribution shall be allocated to each
                     Participant's Account in the same proportion that each such
                     Participant's Compensation for the year bears to the total
                     Compensation of all Participants for such year.

                (ii) Except, however, for any Plan Year beginning prior to
                     January 1, 1990, and if elected in the non-standardized
                     Adoption Agreement for any Plan Year beginning on or after
                     January 1, 1990, a Participant who performs less than a
                     Year of Service during any Plan Year shall not share in the
                     Employer's contribution for that year, unless there is a
                     Short Plan Year or a contribution is required pursuant to
                     Section 4.3(h).

      (c) As of each Anniversary Date or other valuation date, before allocation
          of Employer contributions and Forfeitures, any earnings or losses (net
          appreciation or net depreciation) of the Trust Fund shall be allocated
          in the same proportion that each Participant's and Former
          Participant's nonsegregated accounts bear to the total of all
          Participants' and Former Participants' nonsegregated accounts as of
          such date. If any nonsegregated account of a Participant has been
          distributed prior to the Anniversary Date or other valuation date
          subsequent to a Participant's termination of employment, no earnings
          or losses shall be credited to such account. Notwithstanding the
          above, with respect to contributions made to a 401(k) Plan after the
          previous Anniversary Date or allocation date, the method specified in
          the Adoption Agreement shall be used.

      (d) Participants' Accounts shall be debited for any insurance or annuity
          premiums paid, if any, and credited with any dividends or interest
          received on insurance contracts.

                                       32
<PAGE>
 
      (e) As of each Anniversary Date, any amounts which became Forfeitures
          since the last Anniversary Date shall first be made available to
          reinstate previously forfeited account balances of Former
          Participants, if any, in accordance with Section 6.4(g)(2) or be used
          to satisfy any contribution that may be required pursuant to Section
          3.5 and/or 6.9 or be used to reduce expenses of the Employer incurred
          in the operation of the Plan, as applicable. The remaining
          Forfeitures, if any, shall be treated in accordance with the Adoption
          Agreement. Provided, however, that in the event the allocation of
          Forfeitures provided herein shall cause the "annual addition" (as
          defined in Section 4.4) to any Participant's Account to exceed the
          amount allowable by the Code, the excess shall be reallocated in
          accordance with Section 4.5. Except, however, for any Plan Year
          beginning prior to January 1, 1990, and if elected in the non-
          standardized Adoption Agreement for any Plan Year beginning on or
          after January 1, 1990, a Participant who performs less than a Year of
          Service during any Plan Year shall not share in the Plan Forfeitures
          for that year, unless there is a Short Plan Year or a contribution
          required pursuant to Section 4.3(h).

      (f) Minimum Allocations Required for Top Heavy Plan Years: Notwithstanding
          the foregoing, for any Top Heavy Plan Year, the sum of the Employer's
          contributions and Forfeitures allocated to the Participant's Account
          of each Non-Key Employee shall be equal to at least three percent (3%)
          of such Non-Key Employee's 415 Compensation (reduced by contributions
          and forfeitures, if any, allocated to each Non-Key Employee in any
          defined contribution plan included with this Plan in a Required
          Aggregation Group). However, if (i) the sum of the Employer's
          contributions and Forfeitures allocated to the Participant's Combined
          Account of each Key Employee for such Top Heavy Plan Year is less than
          three percent (3%) of each Key Employee's 415 Compensation and (ii)
          this Plan is not required to be included in an Aggregation Group to
          enable a defined benefit plan to meet the requirements of Code Section
          401(a)(4) or 410, the sum of the Employer's contributions and
          Forfeitures allocated to the Participant's Combined Account of each
          Non-Key Employee shall be equal to the largest percentage allocated to
          the Participant's Combined Account of any Key Employee.

          However, for each Non-Key Employee who is a Participant in a paired
          Profit Sharing Plan or 401(k) Profit Sharing Plan and a paired Money
          Purchase Plan, the minimum 3% allocation specified above shall be
          provided in the Money Purchase Plan.

          If this is an integrated Plan, then for any Top Heavy Plan Year the
          Employer's contribution shall be allocated as follows:

          (1)   An amount equal to 3% multiplied by each Participant's
                Compensation for the Plan Year shall be allocated to each
                Participant's Account. If the Employer does not contribute such
                amount for all Participants, the amount shall be allocated to
                each Participant's Account in the same proportion that his total
                Compensation for the Plan Year bears to the total Compensation
                of all Participants for such year.

                                       33

          (2)   The balance of the Employer's contribution over the amount
                allocated under subparagraph (1) hereof shall be allocated to
                each Participant's Account in a dollar amount equal to 3%
                multiplied by a Participant's Excess Compensation. If the
                Employer does not contribute such amount for all Participants,
                each Participant will be allocated a share of the contribution
                in the same proportion that his Excess Compensation bears to the
                total Excess Compensation of all Participants for that year.

          (3)   The balance of the Employer's contribution over the amount
                allocated under subparagraph (2) hereof shall be allocated to
                each Participant's Account in a dollar amount equal to 2.7%
                multiplied by the sum of each Participant's total 415
                Compensation plus Excess Compensation. If the Employer does not
                contribute such amount for all Participants, each Participant
                will be allocated a share of the contribution in the same
                proportion that his total 415 Compensation plus his total Excess
                Compensation for the Plan Year bears to the total 415
                Compensation plus the total Excess Compensation of all
                Participants for that year.

                Regardless of the preceding, 1.3% shall be substituted for 2.7%
                above if Excess Compensation is based on more than 20% and less
                than or equal to 80% of the Taxable Wage Base. If Excess
                Compensation is based on less than 100% and more than 80% of the
                Taxable Wage Base, then 2.4% shall be substituted for 2.7%
                above.

          (4)   The balance of the Employer's contributions over the amount
                allocated above, if any, shall be allocated to each
                Participant's Account in the same proportion that his total 415
                Compensation for the Plan Year bears to the total 415
                Compensation of all Participants for such year.

                For each Non-Key Employee who is a Participant in this Plan and
                another non-paired defined contribution plan maintained by the
                Employer, the minimum 3% allocation specified above shall be
                provided as specified in F3 of the Adoption Agreement.

      (g) For purposes of the minimum allocations set forth above, the
          percentage allocated to the Participant's Combined Account of any Key
          Employee shall be equal to the ratio of the sum of the Employer's
          contributions and Forfeitures allocated on behalf of such Key Employee
          divided by the 415 Compensation for such Key Employee.

      (h) For any Top Heavy Plan Year, the minimum allocations set forth in this
          Section shall be allocated to the Participant's Combined Account of
          all Non-Key Employees who are Participants and who are employed by the
          Employer on the last day of the Plan Year, including Non-Key Employees
          who have (1) failed to complete a Year of Service; or (2) declined to
          make mandatory contributions (if required) or, in the case of a cash
          or deferred arrangement, Elective Contributions to the Plan.

      (i) Notwithstanding anything herein to the contrary, in any Plan Year in
          which the Employer maintains both this Plan and a defined benefit
          pension plan included in a Required Aggregation Group which is top
          heavy, the Employer shall not be required to provide a Non-Key
          Employee with both the full separate minimum defined benefit plan
          benefit and the full separate defined contribution plan allocations.
          Therefore, if the Employer maintains both a defined benefit and a
          defined contribution plan that are a Top Heavy Group, the top heavy
          minimum benefits shall be provided as follows:

          (1)   Applies if F1b of the Adoption Agreement is Selected -

                (i)  The requirements of Section 2.1 shall apply except that
                     each Non-Key Employee who is a Participant in the Profit
                     Sharing Plan or Money Purchase Plan and who is also a
                     Participant in the defined benefit plan shall receive a
                     minimum allocation of five percent (5%) of such
                     Participant's 415 Compensation from the applicable defined
                     contribution plan(s).

                (ii) For each Non-Key Employee who is a Participant only in the
                     defined benefit plan the Employer will provide a minimum
                     non-integrated benefit equal to 2% of his highest five
                     consecutive year average 415 Compensation for each Year of
                     Service while a Participant in the plan, in which the plan
                     is top heavy, not to exceed ten.

               (iii) For each Non-Key Employee who is a Participant only in this
                     defined contribution plan, the Employer shall provide a
                     contribution equal to 3% of his 415 Compensation.

          (2)   Applies if F1c of the Adoption Agreement is Selected -

                (i)  The minimum allocation specified in Section 4.3(i)(1)(i)
                     shall be 7 1/2% if the Employer elects in the Adoption
                     Agreement for years in which the Plan is top heavy, but not
                     super top heavy.

                (ii) The minimum benefit specified in Section 4.3(i)(1)(ii)
                     shall be 3% if the Employer elects in the Adoption
                     Agreement for years in which the Plan is top heavy, but not
                     super top heavy.

              (iii)  The minimum allocation specified in Section 4.3(i)(1)(iii)
                     shall be 4% if the Employer elects in the Adoption
                     Agreement for years in which the Plan is top heavy, but not
                     super top heavy.

      (j) For the purposes of this Section, 415 Compensation shall be limited to
          the same dollar limitation that is in Section 1.9 (unless adjusted in
          such manner as permitted under Code Section 415(d)). However, for Plan
          Years beginning prior to January 1, 1989, the $200,000 limit shall
          apply only for Top Heavy Plan Years and shall not be adjusted.

                                       35

      (k) Notwithstanding anything herein to the contrary, any Participant who
          terminated employment during the Plan Year for reasons other than
          death, Total and Permanent Disability, or retirement shall or shall
          not share in the allocations of the Employer's Contributions and
          Forfeitures as provided in the Adoption Agreement. Notwithstanding the
          foregoing, for Plan Years beginning after 1989, if this is a
          standardized Plan, any such terminated Participant shall share in the
          allocations as provided in this Section provided such Participant
          completed more than 500 Hours of Service.

          (l)   Notwithstanding anything herein to the contrary, Participants
                terminating for reasons of death, Total and Permanent
                Disability, or retirement shall share in the allocations as
                provided in this Section regardless of whether they completed a
                Year of Service during the Plan Year.

          (m)   If a Former Participant is reemployed after five (5) consecutive
                1-Year Breaks in Service, then separate accounts shall be
                maintained as follows:

                (1)  one account for nonforfeitable benefits attributable to
                     pre-break service; and

                (2)  one account representing his Employer derived account
                     balance in the Plan attributable to post-break service.

4.4   MAXIMUM ANNUAL ADDITIONS

      (a)(1) 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 Code Section 419(e)),
             maintained by the Employer, or an individual medical account (as
             defined in Code Section 415(l)(2)) maintained by the Employer, or a
             simplified employee pension as defined in Code Section 408(k)
             maintained by the Employer, which provides Annual Additions, the
             amount of Annual Additions which may be credited to the
             Participant's accounts for any Limitation Year shall 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 accounts
             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.

         (2) 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.

         (3) As soon as is administratively feasible after the end of the
             Limitation Year, the Maximum Permissible Amount for such Limitation
             Year shall be determined on the basis of the Participant's actual
             compensation for such Limitation Year.

                                       36

      (4) If there is an excess amount pursuant to Section 4.4(a)(2) or Section
          4.5, the excess will be disposed of in one of the following manners,
          as uniformly determined by the Plan Administrator for all Participants
          similarly situated:

          (i)   Any unmatched voluntary Employee contributions (with any gains
                thereon), to the extent they would reduce the Excess Amount,
                will be returned to the Participant;

          (ii)  Any unmatched Elective Contributions (with any gains thereon) to
                the extent they would reduce the Excess Amount, will be returned
                to the Participant;

          (iii) Any matched voluntary Employee contributions (with any gains
                thereon), to the extent they would reduce the Excess Amount,
                will be returned to the Participant. Simultaneously, any
                Employer matching contributions (with any gains thereon) that
                relate to these voluntary contributions, to the extent they
                would reduce the Excess Amount, will be treated as follows: if
                the Participant is covered by the Plan at the end of the
                Limitation Year, such Excess Amount in the Participant's Account
                will be used to reduce Employer contributions for such
                Participant in the next Limitation Year, and succeeding
                Limitation Years, as necessary. If the Participant is not
                covered by the Plan at the end of the Limitation Year, such
                Excess Amount will be held unallocated in a suspense account and
                used to reduce Employer contributions for the next Limitation
                Year (and succeeding Limitation Years, as necessary) for all of
                the remaining Participants in the Plan;

          (iv)  Any matched Elective Contributions (with any gains thereon), to
                the extent they would reduce the Excess Amount, will be returned
                to the Participant. Simultaneously, any Employer matching
                contributions (with any gains thereon) that relate to these
                Elective Contributions, to the extent they would reduce the
                Excess Amount, will be treated in accordance with the same
                procedure which is applied to the Employer matching
                contributions (and gains thereon) under the preceding
                subparagraph (iii).

          (v)   If, after the application of subparagraphs (i), (ii), (iii) and
                (iv), 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 for such Participant in the next
                Limitation Year, and each succeeding Limitation Year, as
                necessary;

          (vi)  If, after the application of subparagraphs (i), (ii), (iii) and
                (iv), an Excess Amount still exists, and the Participant is not
                covered by the Plan at the end of the Limitation Year, the
                Excess Amount will be held unallocated in a suspense account and
                used to reduce Employer contributions for the next Limitation
                Year (and succeeding Limitation Years, as necessary) for all of
                the remaining Participants in the Plan.

                                       37
<PAGE>
 
      (5) 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 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 contributions or any
          Employee contributions may be made to the Plan for that Limitation
          Year. Excess amounts may not be distributed to Participants or Former
          Participants.

   (b)(1) This subsection applies if, in addition to this Plan, the
          Participant is covered under another qualified prototype defined
          contribution plan maintained by the Employer, or a welfare benefit
          fund (as defined in Code Section 419(e)) maintained by the Employer,
          or an individual medical account (as defined in Code Section
          415(l)(2)) maintained by the Employer, or a simplified employee
          pension maintained by the Employer, which provides Annual Additions,
          during any Limitation Year. The Annual Additions which may be credited
          to a Participant's accounts under this Plan for any such Limitation
          Year shall not exceed the Maximum Permissible Amount reduced by the
          Annual Additions credited to a Participant's accounts under the other
          qualified prototype defined contribution plans, welfare benefit funds,
          individual medical accounts and simplified employee pensions for the
          same Limitation Year. If the Annual Additions with respect to the
          Participant under other qualified prototype defined contribution
          plans, welfare benefit funds, individual medical accounts and
          simplified employee pensions 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
          accounts 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 qualified defined contribution plans,
          welfare benefit funds, individual medical accounts and simplified
          employee pensions 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.

      (2) Prior to determining the Participant's actual 415 Compensation for
          the Limitation Year, the Employer may determine the Maximum
          Permissible Amount for a Participant in the manner described in
          Section 4.4(a)(2).

      (3) 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 415
          Compensation for the Limitation Year.

      (4) If as a result of the allocation of Forfeitures, a reasonable error in
          estimating a Participant's annual 415 Compensation, a reasonable error
          in determining the amount of elective deferrals (within the meaning of
          Code Section 402(g)(3)) that may be made with respect to any
          Participant under the limits of Section 4.1, or other facts and
          circumstances to which Regulation 1.415-6(b)(6) shall be applicable, 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

                                       38
<PAGE>
 
          Annual Additions last allocated, except that Annual Additions
          attributable to a simplified employee pension will be deemed to have
          been allocated first, followed by annual additions to a welfare
          benefit fund or individual medical account, regardless of the actual
          allocation date.

      (5) 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:

          (i)   the total Excess Amount allocated as of such date, times

          (ii)  the ratio of (1) the Annual Additions allocated to the
                Participant for the Limitation Year as of such date under this
                Plan to (2) the total Annual Additions allocated to the
                Participant for the Limitation Year as of such date under this
                and all the other qualified prototype defined contribution
                plans.

      (6) Any Excess Amount attributed to this Plan will be disposed in the
          manner described in Section 4.4(a)(4).

  (c) If the Participant is covered under another qualified defined contribution
      plan maintained by the Employer which is not a Prototype Plan, Annual
      Additions which may be credited to the Participant's Account under this
      Plan for any Limitation Year will be limited in accordance with Section
      4.4(b), unless the Employer provides other limitations in the Adoption
      Agreement.

  (d) 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 limited in accordance with the Limitation on
      Allocations Section of the Adoption Agreement.

      Except, however, if the Plans are standardized paired plans, the rate of
      accrual in the defined benefit plan will be reduced to the extent
      necessary so that the sum of the Defined Contribution Fraction and Defined
      Benefit Fraction will equal 1.0.

  (e) For purposes of applying the limitations of Code Section 415, the transfer
      of funds from one qualified plan to another is not an "annual addition."
      In addition, the following are not Employee contributions for the purposes
      of Section 4.4(f)(1)(2): (1) rollover contributions (as defined in Code
      Sections 402(a)(5), 403(a)(4), 403(b)(8) and 408(d)(3)); (2) repayments of
      loans made to a Participant from the Plan; (3) repayments of distributions
      received by an Employee pursuant to Code Section 411(a)(7)(B) (cash-outs);
      (4) repayments of distributions received by an Employee pursuant to Code
      Section 411(a)(3)(D) (mandatory contributions); and (5) Employee
      contributions to a simplified employee pension excludable from gross
      income under Code Section 408(k)(6).

      (f) For purposes of this Section, the following terms shall be defined as
          follows:

          (1)   Annual Additions means the sum credited to a Participant's
                accounts for any Limitation Year of (1) Employer contributions,
                (2) effective with respect to "limitation years" beginning after
                December 31, 1986, Employee contributions, (3) forfeitures, (4)
                amounts allocated, after March 31, 1984, to an individual
                medical account, as defined in Code Section 415(l)(2), which is
                part of a pension or annuity plan maintained by the Employer and
                (5) 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 Code Section 419A(d)(3)) under a welfare benefit fund (as
                defined in Code Section 419(e)) maintained by the Employer.
                Except, however, the 415 Compensation percentage limitation
                referred to in paragraph (a)(2) above shall not apply to: (1)
                any contribution for medical benefits (within the meaning of
                Code Section 419A(f)(2)) after separation from service which is
                otherwise treated as an "annual addition", or (2) any amount
                otherwise treated as an "annual addition" under Code Section
                415(l)(1). Notwithstanding the foregoing, for "limitation years"
                beginning prior to January 1, 1987, only that portion of
                Employee contributions equal to the lesser of Employee
                contributions in excess of six percent (6%) of 415 Compensation
                or one-half of Employee contributions shall be considered an
                "annual addition".

                For this purpose, any Excess Amount applied under Sections
                4.4(a)(4) and 4.4(b)(6) in the Limitation Year to reduce
                Employer contributions shall be considered Annual Additions for
                such Limitation Year.

          (2)   415 Compensation is compensation defined in Section 1.28.

          (3)   Defined Benefit Fraction means 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 Code Sections 415(b) and (d) or 140
                percent of his Highest Average 415 Compensation including any
                adjustments under Code Section 415(b).

                Notwithstanding the above, if the Participant was a Participant
                as of the first day of the first Limitation Year beginning after
                December 31, 1986, in one or more defined benefit plans
                maintained by the Employer which were in existence on May 6,
                1986, the denominator of this fraction will not be less than 125
                percent of the sum of the annual benefits under such plans which
                the Participant had accrued as of the end of the close of the
                last Limitation Year beginning before January 1, 1987,
                disregarding any changes in the terms and conditions of the plan
                after May 5, 1986. The preceding sentence applies only if the
                defined benefit plans individually and in the aggregate
                satisfied the 

                                       40
<PAGE>
 
                requirements of Code Section 415 for all Limitation Years
                beginning before January 1, 1987.

                Notwithstanding the foregoing, for any Top Heavy Plan Year, 100
                shall be substituted for 125 unless the extra minimum allocation
                is being made pursuant to the Employer's election in F1 of the
                Adoption Agreement. However, for any Plan Year in which this
                Plan is a Super Top Heavy Plan, 100 shall be substituted for 125
                in any event.

          (4)   Defined Contribution Dollar Limitation means $30,000, or, if
                greater, one-fourth of the defined benefit dollar limitation set
                forth in Code Section 415(b)(1) as in effect for the Limitation
                Year.

          (5)   Defined Contribution Fraction means 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 voluntary
                employee contributions to any defined benefit plans, whether or
                not terminated, maintained by the Employer and the annual
                additions attributable to all welfare benefit funds, as defined
                in Code Section 419(e), and individual medical accounts, as
                defined in Code Section 415(l)(2), 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 Defined Contribution Dollar Limitation or 35
                percent of the Participant's 415 Compensation for such year. For
                Limitation Years beginning prior to January 1, 1987, the "annual
                addition" shall not be recomputed to treat all Employee
                contributions as an Annual Addition.

                If the Employee was a Participant as of the end of the first day
                of the first Limitation Year beginning after December 31, 1986,
                in one or more defined contribution plans maintained by the
                Employer which were in existence on May 5, 1986, the numerator
                of this fraction will be adjusted if the sum of this fraction
                and the Defined Benefit Fraction would otherwise exceed 1.0
                under the terms of this Plan. Under the adjustment, an amount
                equal to the product of (1) the excess of the sum of the
                fractions over 1.0 times (2) the denominator of this fraction,
                will be permanently subtracted from the numerator of this
                fraction. The adjustment is calculated using the fractions as
                they would be computed as of the end of the last Limitation Year
                beginning before January 1, 1987, and disregarding any changes
                in the terms and conditions of the plan made after May 5, 1986,
                but using the Code Section 415 limitation applicable to the
                first Limitation Year beginning on or after January 1, 1987.

                Notwithstanding the foregoing, for any Top Heavy Plan Year, 100
                shall be substituted for 125 unless the extra minimum allocation
                is being made pursuant to the Employer's election in F1 of the
                Adoption Agreement. However, for any Plan Year in which this
                Plan is a Super Top Heavy Plan, 100 shall be substituted for 125
                in any event.

          (6)   Employer means the Employer that adopts this Plan and all
                Affiliated Employers, except that for purposes of this Section,
                Affiliated Employers shall be determined pursuant to the
                modification made by Code Section 415(h).

          (7)   Excess Amount means the excess of the Participant's Annual
                Additions for the Limitation Year over the Maximum Permissible
                Amount.

          (8)   Highest Average Compensation means the average Compensation for
                the three consecutive Years of Service with the Employer that
                produces the highest average. A Year of Service with the
                Employer is the 12 consecutive month period defined in Section
                E1 of the Adoption Agreement which is used to determine
                Compensation under the Plan.

          (9)   Limitation Year means the Compensation Year (a 12 consecutive
                month period) as elected by the Employer in the Adoption
                Agreement. All qualified plans maintained by the Employer must
                use the same Limitation Year. If the Limitation Year is amended
                to a different 12 consecutive month period, the new Limitation
                Year must begin on a date within the Limitation Year in which
                the amendment is made.

          (10)  Master or Prototype Plan means a plan the form of which is the
                subject of a favorable opinion letter from the Internal Revenue
                Service.

          (11)  Maximum Permissible Amount means the maximum Annual Addition
                that may be contributed or allocated to a Participant's account
                under the plan for any Limitation Year, which shall not exceed
                the lesser of:

                (i)  the Defined Contribution Dollar Limitation, or

                (ii) 25 percent of the Participant's 415 Compensation for the
                     Limitation Year.

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

                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 Contribution multiplied by the
                following fraction:

                        number of months in the short Limitation Year
                        ---------------------------------------------
                                              12

          (12)  Projected Annual Benefit means 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:

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

                (ii) the Participant's 415 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.

                For purposes of this Section, straight life annuity means an
                annuity payable in equal installments for the life of the
                Participant that terminates upon the Participant's death.

      (g) Notwithstanding anything contained in this Section to the contrary,
          the limitations, adjustments and other requirements prescribed in this
          Section shall at all times comply with the provisions of Code Section
          415 and the Regulations thereunder, the terms of which are
          specifically incorporated herein by reference.

4.5   ADJUSTMENT FOR EXCESSIVE ANNUAL ADDITIONS

      If as a result of the allocation of Forfeitures, a reasonable error in
      estimating a Participant's annual 415 Compensation, a reasonable error in
      determining the amount of elective deferrals (within the meaning of Code
      Section 402(g)(3)) that may be made with respect to any Participant under
      the limits of Section 4.4, or other facts and circumstances to which
      Regulation 1.415-6(b)(6) shall be applicable, the "annual additions" under
      this Plan would cause the maximum provided in Section 4.4 to be exceeded,
      the Administrator shall treat the excess in accordance with Section
      4.4(a)(4).

                                       43

4.6   TRANSFERS FROM QUALIFIED PLANS

      (a) If specified in the Adoption Agreement and with the consent of the
          Administrator, amounts may be transferred from other qualified plans,
          provided that the trust from which such funds are transferred permits
          the transfer to be made and the transfer will not jeopardize the tax
          exempt status of the Plan or create adverse tax consequences for the
          Employer. The amounts transferred shall be set up in a separate
          account herein referred to as a "Participant's Rollover Account." Such
          account shall be fully Vested at all times and shall not be subject to
          forfeiture for any reason.

      (b) Amounts in a Participant's Rollover Account shall be held by the
          Trustee pursuant to the provisions of this Plan and may not be
          withdrawn by, or distributed to the Participant, in whole or in part,
          except as provided in Paragraphs (c) and (d) of this Section.

      (c) Amounts attributable to elective contributions (as defined in
          Regulation 1.401(k)-1(g)(4)), including amounts treated as elective
          contributions, which are transferred from another qualified plan in a
          plan-to-plan transfer shall be subject to the distribution limitations
          provided for in Regulation 1.401(k)-1(d).

      (d) At Normal Retirement Date, or such other date when the Participant or
          his Beneficiary shall be entitled to receive benefits, the fair market
          value of the Participant's Rollover Account shall be used to provide
          additional benefits to the Participant or his Beneficiary. Any
          distributions of amounts held in a Participant's Rollover Account
          shall be made in a manner which is consistent with and satisfies the
          provisions of Section 6.5, including, but not limited to, all notice
          and consent requirements of Code Sections 411(a)(11) and 417 and the
          Regulations thereunder. Furthermore, such amounts shall be considered
          as part of a Participant's benefit in determining whether an
          involuntary cash-out of benefits without Participant consent may be
          made.

      (e) The Administrator may direct that employee transfers made after a
          valuation date be segregated into a separate account for each
          Participant until such time as the allocations pursuant to this Plan
          have been made, at which time they may remain segregated or be
          invested as part of the general Trust Fund, to be determined by the
          Administrator.

      (f) For purposes of this Section, the term "qualified plan" shall mean any
          tax qualified plan under Code Section 401(a). The term "amounts
          transferred from other qualified plans" shall mean: (i) amounts
          transferred to this Plan directly from another qualified plan; (ii)
          lump-sum distributions received by an Employee from another qualified
          plan which are eligible for tax free rollover to a qualified plan and
          which are transferred by the Employee to this Plan within sixty (60)
          days following his receipt thereof; (iii) amounts transferred to this
          Plan from a conduit individual retirement account provided that the
          conduit individual retirement account has no assets other than assets
          which (A) were previously distributed to the Employee by another
          qualified plan as a lump-sum distribution (B) were eligible for tax-
          free rollover to a qualified plan and (C) were deposited in such
          conduit individual retirement account within sixty (60) days of
          receipt thereof and other than earnings on said assets; and (iv)
          amounts distributed to the 

                                       44
<PAGE>
 
          Employee from a conduit individual retirement account meeting the
          requirements of clause (iii) above, and transferred by the Employee to
          this Plan within sixty (60) days of his receipt thereof from such
          conduit individual retirement account.

      (g) Prior to accepting any transfers to which this Section applies, the
          Administrator may require the Employee to establish that the amounts
          to be transferred to this Plan meet the requirements of this Section
          and may also require the Employee to provide an opinion of counsel
          satisfactory to the Employer that the amounts to be transferred meet
          the requirements of this Section.

      (h) Notwithstanding anything herein to the contrary, a transfer directly
          to this Plan from another qualified plan (or a transaction having the
          effect of such a transfer) shall only be permitted if it will not
          result in the elimination or reduction of any "Section 411(d)(6)
          protected benefit" as described in Section 8.1.

4.7   VOLUNTARY CONTRIBUTIONS

      (a) If this is an amendment to a Plan that had previously allowed
          voluntary Employee contributions, then, except as provided in 4.7(b)
          below, this Plan will not accept voluntary Employee contributions for
          Plan Years beginning after the Plan Year in which this Plan is adopted
          by the Employer.

      (b) For 401(k) Plans, if elected in the Adoption Agreement, each
          Participant may, at the discretion of the Administrator in a
          nondiscriminatory manner, elect to voluntarily contribute a portion of
          his compensation earned while a Participant under this Plan. In
          addition, if specified in the Adoption Agreement, a voluntary
          contribution shall be eligible for a matching contribution. Such
          contributions shall be paid to the Trustee within a reasonable period
          of time but in no event later than 90 days after the receipt of the
          contribution.

      (c) The balance in each Participant's Voluntary Contribution Account shall
          be fully Vested at all times and shall not be subject to Forfeiture
          for any reason.

      (d) A Participant may elect to withdraw his voluntary contributions from
          his Voluntary Contribution Account and the actual earnings thereon in
          a manner which is consistent with and satisfies the provisions of
          Section 6.5, including, but not limited to, all notice and consent
          requirements of Code Sections 411(a)(11) and 417 and the Regulations
          thereunder. If the Administrator maintains sub-accounts with respect
          to voluntary contributions (and earnings thereon) which were made on
          or before a specified date, a Participant shall be permitted to
          designate which sub-account shall be the source for his withdrawal. No
          Forfeitures shall occur solely as a result of an Employee's withdrawal
          of Employee contributions.

          If applicable, and in the event that a Participant elects to make a
          withdrawal of any portion of his matched voluntary contributions, such
          Participant will be subject to a suspension period of three months
          duration from the date of such withdrawal, during which time such
          Participant will not be eligible to make any voluntary contributions.

                                       45
<PAGE>
 
          In the event a Participant has received a hardship distribution
          pursuant to Regulation 1.401(k)-1(d)(2)(iii)(B) from any plan
          maintained by the Employer, then such Participant shall be barred from
          making any voluntary contributions for a period of twelve (12) months
          after receipt of the withdrawal or distribution.

      (e) At Normal Retirement Date, or such other date when the Participant or
          his Beneficiary shall be entitled to receive benefits, the fair market
          value of the Voluntary Contribution Account shall be used to provide
          additional benefits to the Participant or his Beneficiary.

      (f) The Administrator may direct that voluntary contributions made after a
          valuation date be segregated into a separate account until such time
          as the allocations pursuant to this Plan have been made, at which time
          they may remain segregated or be invested as part of the general Trust
          Fund, to be determined by the Administrator.

4.8   DIRECTED INVESTMENT ACCOUNT

      (a) If elected in the Adoption Agreement, all Participants may direct the
          Trustee as to the investment of all or a portion of any one or more of
          their individual account balances. Participants may direct the Trustee
          in writing to invest their account in specific assets as permitted by
          the Administrator provided such investments are in accordance with the
          Department of Labor regulations and are permitted by the Plan. That
          portion of the account of any Participant so directing will thereupon
          be considered a Directed Investment Account.

      (b) A separate Directed Investment Account shall be established for each
          Participant who has directed an investment. Transfers between the
          Participant's regular account and their Directed Investment Account
          shall be charged and credited as the case may be to each account. The
          Directed Investment Account shall not share in Trust Fund Earnings,
          but it shall be charged or credited as appropriate with the net
          earnings, gains, losses and expenses as well as any appreciation or
          depreciation in market value during each Plan Year attributable to
          such account.

      (c) The Administrator shall establish a procedure, to be applied in a
          uniform and nondiscriminatory manner, setting forth the permissible
          investment options under this Section, how often changes between
          investments may be made, and any other limitations that the
          Administrator shall impose on a Participant's right to direct
          investments.

4.9   QUALIFIED VOLUNTARY EMPLOYEE CONTRIBUTIONS

      (a) If this is an amendment to a Plan that previously permitted deductible
          voluntary contributions, then each Participant who made a "Qualified
          Voluntary Employee Contribution" within the meaning of Code Section
          219(e)(2) as it existed prior to the enactment of the Tax Reform Act
          of 1986, shall have his contribution held in a separate Qualified
          Voluntary Employee Contribution Account which shall be fully Vested at
          all times. Such contributions, however, shall not be permitted if they
          are attributable to taxable years beginning after December 31, 1986.

                                       46
<PAGE>
 
      (b) A Participant may, upon written request delivered to the
          Administrator, make withdrawals from his Qualified Voluntary Employee
          Contribution Account. Any distribution shall be made in a manner which
          is consistent with and satisfies the provisions of Section 6.5,
          including, but not limited to, all notice and consent requirements of
          Code Sections 411(a)(11) and 417 and the Regulations thereunder.

      (c) At Normal Retirement Date, or such other date when the Participant or
          his Beneficiary shall be entitled to receive benefits, the fair market
          value of the Qualified Voluntary Employee Contribution Account shall
          be used to provide additional benefits to the Participant or his
          Beneficiary.

      (d) Unless the Administrator directs Qualified Voluntary Employee
          Contributions made pursuant to this Section be segregated into a
          separate account for each Participant, they shall be invested as part
          of the general Trust Fund and share in earnings and losses.

4.10  ACTUAL CONTRIBUTION PERCENTAGE TESTS

      In the event this Plan previously provided for voluntary or mandatory
      Employee contributions, then, with respect to Plan Years beginning after
      December 31, 1986, such contributions must satisfy the provisions of Code
      Section 401(m) and the Regulations thereunder.

4.11  INTEGRATION IN MORE THAN ONE PLAN

      If the Employer and/or an Affiliated Employer maintain qualified
      retirement plans integrated with Social Security such that any Participant
      in this Plan is covered under more than one of such plans, then such plans
      will be considered to be one plan and will be considered to be integrated
      if the extent of the integration of all such plans does not exceed 100%.
      For purposes of the preceding sentence, the extent of integration of a
      plan is the ratio, expressed as a percentage, which the actual benefits,
      benefit rate, offset rate, or employer contribution rate, whatever is
      applicable under the Plan bears to the limitation applicable to such Plan.
      If the Employer maintains two or more standardized paired plans, only one
      plan may be integrated with Social Security.

                                   ARTICLE V
                                  VALUATIONS

5.1   VALUATION OF THE TRUST FUND

      The Administrator shall direct the Trustee, as of each Anniversary Date,
      and at such other date or dates deemed necessary by the Administrator,
      herein called "valuation date," to determine the net worth of the assets
      comprising the Trust Fund as it exists on the "valuation date." In
      determining such net worth, the Trustee shall value the assets comprising
      the Trust Fund at their fair market value as of the "valuation date" and
      shall deduct all expenses for which the Trustee has not yet obtained
      reimbursement from the Employer or the Trust Fund.

                                       47
<PAGE>
 
5.2   METHOD OF VALUATION

      In determining the fair market value of securities held in the Trust Fund
      which are listed on a registered stock exchange, the Administrator shall
      direct the Trustee to value the same at the prices they were last traded
      on such exchange preceding the close of business on the "valuation date."
      If such securities were not traded on the "valuation date," or if the
      exchange on which they are traded was not open for business on the
      "valuation date," then the securities shall be valued at the prices at
      which they were last traded prior to the "valuation date." Any unlisted
      security held in the Trust Fund shall be valued at its bid price next
      preceding the close of business on the "valuation date," which bid price
      shall be obtained from a registered broker or an investment banker. In
      determining the fair market value of assets other than securities for
      which trading or bid prices can be obtained, the Trustee may appraise such
      assets itself, or in its discretion, employ one or more appraisers for
      that purpose and rely on the values established by such appraiser or
      appraisers.

                                  ARTICLE VI
                  DETERMINATION AND DISTRIBUTION OF BENEFITS

6.1   DETERMINATION OF BENEFITS UPON RETIREMENT

      Every Participant may terminate his employment with the Employer and
      retire for the purposes hereof on or after his Normal Retirement Date or
      Early Retirement Date. Upon such Normal Retirement Date or Early
      Retirement Date, all amounts credited to such Participant's Combined
      Account shall become distributable. However, a Participant may postpone
      the termination of his employment with the Employer to a later date, in
      which event the participation of such Participant in the Plan, including
      the right to receive allocations pursuant to Section 4.3, shall continue
      until his Late Retirement Date. Upon a Participant's Retirement Date, or
      as soon thereafter as is practicable, the Administrator shall direct the
      distribution of all amounts credited to such Participant's Combined
      Account in accordance with Section 6.5.

6.2   DETERMINATION OF BENEFITS UPON DEATH

      (a) Upon the death of a Participant before his Retirement Date or other
          termination of his employment, all amounts credited to such
          Participant's Combined Account shall become fully Vested. The
          Administrator shall direct, in accordance with the provisions of
          Sections 6.6 and 6.7, the distribution of the deceased Participant's
          accounts to the Participant's Beneficiary.

      (b) Upon the death of a Former Participant, the Administrator shall
          direct, in accordance with the provisions of Sections 6.6 and 6.7, the
          distribution of any remaining amounts credited to the accounts of such
          deceased Former Participant to such Former Participant's Beneficiary.

      (c) The Administrator may require such proper proof of death and such
          evidence of the right of any person to receive payment of the value of
          the account of a deceased Participant or Former Participant as the
          Administrator may deem desirable. The Administrator's determination of
          death and of the right of any person to receive payment shall be
          conclusive.

      (d) Unless otherwise elected in the manner prescribed in Section 6.6, the
          Beneficiary of the Pre-Retirement Survivor Annuity shall be the
          Participant's spouse. Except, however, the Participant may designate a
          Beneficiary other than his spouse for the Pre-Retirement Survivor
          Annuity if:

          (1)   the Participant and his spouse have validly waived the Pre-
                Retirement Survivor Annuity in the manner prescribed in Section
                6.6, and the spouse has waived his or her right to be the
                Participant's Beneficiary, or

          (2)   the Participant is legally separated or has been abandoned
                (within the meaning of local law) and the Participant has a
                court order to such effect (and there is no 

                                       49
<PAGE>
 
                "qualified domestic relations order" as defined in Code Section
                414(p) which provides otherwise), or

          (3)   the Participant has no spouse, or

          (4)   the spouse cannot be located.

          In such event, the designation of a Beneficiary shall be made on a
          form satisfactory to the Administrator. 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
          Administrator. However, the Participant's spouse must again consent in
          writing to any change in Beneficiary unless the original consent
          acknowledged that the spouse had the right to limit consent only to a
          specific Beneficiary and that the spouse voluntarily elected to
          relinquish such right. If a 50% Pre-Retirement Survivor Annuity is
          specified in the Adoption Agreement, the Participant may, at any time,
          designate a Beneficiary for death benefits payable under the Plan that
          are in excess of the Pre-Retirement Survivor Annuity. In the event no
          valid designation of Beneficiary exists at the time of the
          Participant's death, the death benefit shall be payable to his estate.

      (e) If the Plan provides an insured death benefit and a Participant dies
          before any insurance coverage to which he is entitled under the Plan
          is effected, his death benefit from such insurance coverage shall be
          limited to the standard rated premium which was or should have been
          used for such purpose.

      (f) In the event of any conflict between the terms of this Plan and the
          terms of any Contract issued hereunder, the Plan provisions shall
          control.

6.3   DETERMINATION OF BENEFITS IN EVENT OF DISABILITY

      In the event of a Participant's Total and Permanent Disability prior to
      his Retirement Date or other termination of his employment, all amounts
      credited to such Participant's Combined Account shall become fully Vested.
      In the event of a Participant's Total and Permanent Disability, the
      Administrator, in accordance with the provisions of Sections 6.5 and 6.7,
      shall direct the distribution to such Participant of all amounts credited
      to such Participant's Combined Account as though he had retired.

                                       50
<PAGE>
 
6.4   DETERMINATION OF BENEFITS UPON TERMINATION

      (a) On or before the Anniversary Date, or other valuation date, coinciding
          with or subsequent to the termination of a Participant's employment
          for any reason other than retirement, death, or Total and Permanent
          Disability, the Administrator may direct that the amount of the Vested
          portion of such Terminated Participant's Combined Account be
          segregated and invested separately. In the event the Vested portion of
          a Participant's Combined Account is not segregated, the amount shall
          remain in a separate account for the Terminated Participant and share
          in allocations pursuant to Section 4.3 until such time as a
          distribution is made to the Terminated Participant. The amount of the
          portion of the Participant's Combined Account which is not Vested may
          be credited to a separate account (which will always share in gains
          and losses of the Trust Fund) and, at such time as the amount becomes
          a Forfeiture, shall be treated in accordance with the provisions of
          the Plan regarding Forfeitures.

          Regardless of whether distributions in kind are permitted, in the
          event that the amount of the Vested portion of the Terminated
          Participant's Combined Account equals or exceeds the fair market value
          of any insurance Contracts, the Trustee, when so directed by the
          Administrator and agreed to by the Terminated Participant, shall
          assign, transfer, and set over to such Terminated Participant all
          Contracts on his life in such form or with such endorsements, so that
          the settlement options and forms of payment are consistent with the
          provisions of Section 6.5. In the event that the Terminated
          Participant's Vested portion does not at least equal the fair market
          value of the Contracts, if any, the Terminated Participant may pay
          over to the Trustee the sum needed to make the distribution equal to
          the value of the Contracts being assigned or transferred, or the
          Trustee, pursuant to the Participant's election, may borrow the cash
          value of the Contracts from the Insurer so that the value of the
          Contracts is equal to the Vested portion of the Terminated
          Participant's Combined Account and then assign the Contracts to the
          Terminated Participant.

          At the election of the Terminated Participant, distribution of the
          funds due to the Terminated Participant shall be made on the
          occurrence of an event which would result in the distribution had the
          Terminated Participant remained in the employ of the Employer (upon
          the Participant's death, Total and Permanent Disability, Early or
          Normal Retirement). However, at the election of the Participant, the
          Administrator shall direct that the entire Vested portion or, if
          selected in the Adoption Agreement, a partial Vested portion of the
          Terminated Participant's Combined Account to be payable to such
          Terminated Participant provided the conditions, if any, set forth in
          the Adoption Agreement have been satisfied. Any distribution under
          this paragraph shall be made in a manner which is consistent with and
          satisfies the provisions of Section 6.5 including, but not limited to,
          all notice and consent requirements of Code Sections 411(a)(11) and
          417 and the Regulations thereunder.

          Notwithstanding the above, if the value of a Terminated Participant's
          Vested benefit derived from Employer and Employee contributions does
          not exceed, and at the time of any prior distribution, has never
          exceeded $3,500 or such lesser amount, as specified in the Adoption
          Agreement, the Administrator shall direct that the entire Vested
          benefit be 

                                       51
<PAGE>
 
          paid to such Participant in a single lump-sum without regard to the
          consent of the Participant or the Participant's spouse. A
          Participant's Vested benefit shall not include Qualified Voluntary
          Employee Contributions within the meaning of Code Section 72(o)(5)(B)
          for Plan Years beginning prior to January 1, 1989.

      (b) The Vested portion of any Participant's Account shall be a percentage
          of such Participant's Account determined on the basis of the
          Participant's number of Years of Service according to the vesting
          schedule specified in the Adoption Agreement.

      (c) For any Top Heavy Plan Year, one of the minimum top heavy vesting
          schedules as elected by the Employer in the Adoption Agreement will
          automatically apply to the Plan. The minimum top heavy vesting
          schedule applies to all benefits within the meaning of Code Section
          411(a)(7) except those attributable to Employee contributions,
          including benefits accrued before the effective date of Code Section
          416 and benefits accrued before the Plan became top heavy. Further, no
          decrease in a Participant's Vested percentage may occur in the event
          the Plan's status as top heavy changes for any Plan Year. However,
          this Section does not apply to the account balances of any Employee
          who does not have an Hour of Service after the Plan has initially
          become top heavy and the Vested percentage of such Employee's
          Participant's Account shall be determined without regard to this
          Section 6.4(c).

          If in any subsequent Plan Year, the Plan ceases to be a Top Heavy
          Plan, the Administrator shall continue to use the vesting schedule in
          effect while the Plan was a Top Heavy Plan.

      (d) Notwithstanding the vesting schedule above, upon the complete
          discontinuance of the Employer's contributions to the Plan or upon any
          full or partial termination of the Plan, all amounts credited to the
          account of any affected Participant shall become 100% Vested and shall
          not thereafter be subject to Forfeiture.

      (e) If this is an amended or restated Plan, then notwithstanding the
          vesting schedule specified in the Adoption Agreement, the Vested
          percentage of a Participant's Account shall not be less than the
          Vested percentage attained as of the later of the effective date or
          adoption date of this amendment and restatement. The computation of a
          Participant's nonforfeitable percentage of his interest in the Plan
          shall not be reduced as the result of any direct or indirect amendment
          to this Article, or due to changes in the Plan's status as a Top Heavy
          Plan.

      (f) If the Plan's vesting schedule is amended, or if the Plan is amended
          in any way that directly or indirectly affects the computation of the
          Participant's nonforfeitable percentage or if the Plan is deemed
          amended by an automatic change to a top heavy vesting schedule, then
          each Participant with at least 3 Years of Service as of the expiration
          date of the election period may elect to have his nonforfeitable
          percentage computed under the Plan without regard to such amendment or
          change. Notwithstanding the foregoing, for Plan Years beginning before
          January 1, 1989, or with respect to Employees who fail to complete at
          least one (1) Hour of Service in a Plan Year beginning after December
          31, 1988, five (5) shall be substituted for three (3) in the 

                                       52
<PAGE>
 
          preceding sentence. If a Participant fails to make such election, then
          such Participant shall be subject to the new vesting schedule. The
          Participant's election period shall commence on the adoption date of
          the amendment and shall end 60 days after the latest of:

          (1)   the adoption date of the amendment,

          (2)   the effective date of the amendment, or

          (3)   the date the Participant receives written notice of the
                amendment from the Employer or Administrator.

    (g)(1)If any Former Participant shall be reemployed by the Employer before a
          1-Year Break in Service occurs, he shall continue to participate in
          the Plan in the same manner as if such termination had not occurred.

       (2)If any Former Participant shall be reemployed by the Employer before
          five (5) consecutive 1-Year Breaks in Service, and such Former
          Participant had received a distribution of his entire Vested interest
          prior to his reemployment, his forfeited account shall be reinstated
          only if he repays the full amount distributed to him before the
          earlier of five (5) years after the first date on which the
          Participant is subsequently reemployed by the Employer or the close of
          the first period of 5 consecutive 1-Year Breaks in Service commencing
          after the distribution. If a distribution occurs for any reason other
          than a separation from service, the time for repayment may not end
          earlier than five (5) years after the date of separation. In the event
          the Former Participant does repay the full amount distributed to him,
          the undistributed portion of the Participant's Account must be
          restored in full, unadjusted by any gains or losses occurring
          subsequent to the Anniversary Date or other valuation date preceding
          his termination. If an Employee receives a distribution pursuant to
          this section and the Employee resumes employment covered under this
          Plan, the Employee's Employer-derived account balance will be restored
          to the amount on the date of distribution if the Employee repays to
          the Plan the full amount of the distribution attributable to Employer
          contributions before the earlier of 5 years after the first date on
          which the Participant is subsequently re-employed by the Employer, or
          the date the Participant incurs 5 consecutive 1-Year Breaks in Service
          following the date of the distribution. If a non-Vested Former
          Participant was deemed to have received a distribution and such Former
          Participant is reemployed by the Employer before five (5) consecutive
          1-Year Breaks in Service, then such Participant will be deemed to have
          repaid the deemed distribution as of the date of reemployment.

       (3)If specified in the Adoption Agreement, if any Former Participant is
          reemployed after a 1-Year Break in Service has occurred, Years of
          Service shall include Years of Service prior to his 1-Year Break in
          Service subject to the following rules:

          (i)   Any Former Participant who under the Plan does not have a
                nonforfeitable right to any interest in the Plan resulting from
                Employer contributions shall lose credits if his consecutive 1-
                Year Breaks in Service equal or exceed the 

                                       53
<PAGE>
 
                greater of (A) five (5) or (B) the aggregate number of his pre-
                break Years of Service;

          (ii)  After five (5) consecutive 1-Year Breaks in Service, a Former
                Participant's Vested account balance attributable to pre-break
                service shall not be increased as a result of post-break
                service;

          (iii) A Former Participant who is reemployed and who has not had his
                Years of Service before a 1-Year Break in Service disregarded
                pursuant to (i) above, shall participate in the Plan as of his
                date of reemployment;

          (iv)  If a Former Participant completes a Year of Service (a 1-Year
                Break in Service previously occurred, but employment had not
                terminated), he shall participate in the Plan retroactively from
                the first day of the Plan Year during which he completes one (1)
                Year of Service.

      (4) If specified in the Adoption Agreement, if any Former Participant is
          reemployed after a 1-Year Break in Service has occurred, Years of
          Service shall include Years of Service prior to his 1-Year Break in
          Service subject to the following rules:

          (i)   If a Former Participant subsequently resumes his employment with
                the Employer, his prior Years of Service shall be used in
                computing his Years of Service;

          (ii)  After five (5) consecutive 1-Year Breaks in Service, a Former
                Participant's Vested account balance attributable to pre-break
                service shall not be increased as a result of post-break
                service;

          (iii) A Former Participant shall be eligible to become a Participant
                on the day on which he resumes service with the Employer
                provided he is an Eligible Employee;

          (iv)  An Eligible Employee who was not previously a Participant and
                who has had a 1-Year Break in Service and who, prior to that
                break, had satisfied the service requirement, pursuant to the
                Adoption Agreement, shall become a Participant on the first
                Entry Date, as specified in the Adoption Agreement, provided he
                has satisfied any age requirement specified in the Adoption
                Agreement.

      (h) If the Terminated Participant elects to have distributed less than the
          entire Vested portion of his account balance that is derived from
          Employer contributions, the part of the non-Vested portion that will
          be treated as a Forfeiture is the total non-Vested portion multiplied
          by a fraction, the numerator of which is the amount of the
          distribution attributable to Employer contributions and the
          denominator of which is the total value of the Vested Employer-derived
          Participant's account balance.

          (i)   In determining Years of Service for purposes of vesting under
                the Plan, Years of Service shall be excluded as specified in the
                Adoption Agreement.

6.5   DISTRIBUTION OF BENEFITS

   (a)(1) Unless otherwise elected as provided below, a Participant who is
          married on the "annuity starting date" and who does not die before the
          "annuity starting date" shall receive the value of all of his benefits
          in the form of a Joint and Survivor Annuity. The Joint and Survivor
          Annuity is an annuity that commences immediately and shall be equal in
          value to a single life annuity. Such joint and survivor benefits
          following the Participant's death shall continue to the spouse during
          the spouse's lifetime at a rate equal to 50% of the rate at which such
          benefits were payable to the Participant. This Joint and Survivor
          Annuity shall be considered the designated qualified Joint and
          Survivor Annuity and automatic form of payment for the purposes of
          this Plan. However, the Participant may elect to receive a smaller
          annuity benefit with continuation of payments to the spouse at a rate
          of seventy-five percent (75%) or one hundred percent (100%) of the
          rate payable to a Participant during his lifetime which alternative
          Joint and Survivor Annuity shall be equal in value to the automatic
          Joint and 50% Survivor Annuity. An unmarried Participant shall receive
          the value of his benefit in the form of a single life annuity. Such
          unmarried Participant, however, may elect in writing to waive the
          single life annuity. The election must comply with the provisions of
          this Section as if it were an election to waive the Joint and Survivor
          Annuity by a married Participant, but without the spousal consent
          requirement. The Participant may elect to have any annuity provided
          for in this Section distributed upon the attainment of the "earliest
          retirement age" under the Plan. The "earliest retirement age" is the
          earliest date on which, under the Plan, the Participant could elect to
          receive retirement benefits.

      (2) Any election to waive the Joint and Survivor Annuity must be made by
          the Participant in writing during the election period and be consented
          to by the Participant's spouse. If the spouse is legally incompetent
          to give consent, the spouse's legal guardian, even if such guardian is
          the Participant, may give consent. Such election shall designate a
          Beneficiary (or a form of benefits) that may not be changed without
          spousal consent (unless the consent of the spouse expressly permits
          designations by the Participant without the requirement of further
          consent by the spouse). Such spouse's consent shall be irrevocable and
          must acknowledge the effect of such election and be witnessed by a
          Plan representative or a notary public. Such consent shall not be
          required if it is established to the satisfaction of the Administrator
          that the required consent cannot be obtained because there is no
          spouse, the spouse cannot be located, or other circumstances that may
          be prescribed by Regulations. The election made by the Participant and
          consented to by his spouse may be revoked by the Participant in
          writing without the consent of the spouse at any time during the
          election period. The number of revocations shall not be limited. Any
          new election must comply with the requirements of this paragraph. A
          former spouse's waiver shall not be binding on a new spouse.

      (3) The election period to waive the Joint and Survivor Annuity shall be
          the 90 day period ending on the "annuity starting date."

      (4) For purposes of this Section and Section 6.6, the "annuity starting
          date" means the first day of the first period for which an amount is
          paid as an annuity, or, in the case of a 

                                       55
<PAGE>
 
          benefit not payable in the form of an annuity, the first day on which
          all events have occurred which entitles the Participant to such
          benefit.

      (5) For purposes of this Section and Section 6.6, a "single life annuity"
          means an annuity paid in equal installments for the life of a
          Participant that terminates upon the Participant's death.

      (6) With regard to the election, the Administrator shall provide to the
          Participant no less than 30 days and no more than 90 days before the
          "annuity starting date" a written explanation of:

          (i)   the terms and conditions of the Joint and Survivor Annuity, and

          (ii)  the Participant's right to make and the effect of an election to
                waive the Joint and Survivor Annuity, and

          (iii) the right of the Participant's spouse to consent to any election
                to waive the Joint and Survivor Annuity, and

          (iv)  the right of the Participant to revoke such election, and the
                effect of such revocation.

   (b)    In the event a married Participant duly elects pursuant to 
          paragraph (a)(2) above not to receive his benefit in the form of a
          Joint and Survivor Annuity, or if such Participant is not married, in
          the form of a single life annuity, the Administrator, pursuant to the
          election of the Participant, shall direct the distribution to a
          Participant or his Beneficiary any amount to which he is entitled
          under the Plan in one or more of the following methods which are
          permitted pursuant to the Adoption Agreement:

          (1)   One lump sum payment in cash or in property;

          (2)   One or more partial distributions in cash or in property;

          (3)   Payments over a period certain in monthly, quarterly,
                semiannual, or annual cash installments. In order to provide
                such installment payments, the Administrator may direct that the
                Participant's interest in the Plan be segregated and invested
                separately, and that the funds in the segregated account be used
                for the payment of the installments. The period over which such
                payment is to be made shall not extend beyond the Participant's
                life expectancy (or the life expectancy of the Participant and
                his designated Beneficiary);

          (4)   Purchase of or providing an annuity. However, such annuity may
                not be in any form that will provide for payments over a period
                extending beyond either the life of the Participant (or the
                lives of the Participant and his designated Beneficiary) or the
                life expectancy of the Participant (or the life expectancy of
                the Participant and his designated Beneficiary).

                                       56
<PAGE>
 
      (c) The present value of a Participant's Joint and Survivor Annuity
          derived from Employer and Employee contributions may not be paid
          without his written consent if the value exceeds, or has ever exceeded
          at the time of any prior distribution, $3,500 (or such lesser amount,
          as specified in the Adoption Agreement). Further, the spouse of a
          Participant must consent in writing to any immediate distribution not
          paid in the form of a Joint and Survivor Annuity; however, if the
          value of the Participant's Vested benefit derived from Employer and
          Employee contributions does not exceed $3,500 (or such lesser amount,
          as specified in the Adoption Agreement) and has never exceeded such
          dollar limit at the time of any prior distribution, the Administrator
          may immediately distribute such benefit without any consent. No
          distribution may be made under the preceding sentence after the
          "annuity starting date" unless the Participant and his spouse consent
          in writing to such distribution. Any written consent required under
          this paragraph must be obtained not more than 90 days before
          commencement of the distribution and shall be made in a manner
          consistent with Section 6.5(a)(2).

      (d) Any distribution to a Participant who has a benefit which exceeds, or
          has ever exceeded at the time of any prior distribution, $3,500 (or
          such lesser amount, as specified in the Adoption Agreement) shall
          require such Participant's consent if such distribution commences
          prior to the later of his Normal Retirement Age or age 62. With regard
          to this required consent:

          (1)   No consent shall be valid unless the Participant has received a
                general description of the material features and an explanation
                of the relative values of the optional forms of benefit
                available under the Plan that would satisfy the notice
                requirements of Code Section 417.

          (2)   The Participant must be informed of his right to defer receipt
                of the distribution. If a Participant fails to consent, it shall
                be deemed an election to defer the commencement of payment of
                any benefit. However, any election to defer the receipt of
                benefits shall not apply with respect to distributions which are
                required under Section 6.5(e).

          (3)   Notice of the rights specified under this paragraph shall be
                provided no less than 30 days and no more than 90 days before
                the "annuity starting date."

          (4)   Written consent of the Participant to the distribution must not
                be made before the Participant receives the notice and must not
                be made more than 90 days before the "annuity starting date."

          (5)   No consent shall be valid if a significant detriment is imposed
                under the Plan on any Participant who does not consent to the
                distribution.

      (e) Notwithstanding any provision in the Plan to the contrary, the
          distribution of a Participant's benefits, made on or after January 1,
          1985, whether under the Plan or through the purchase of an annuity
          Contract, shall be made in accordance with the following requirements
          and shall otherwise comply with Code Section 401(a)(9) and the

                                       57
<PAGE>
 
          Regulations thereunder (including Regulation Section 1.401(a)(9)-2),
          the provisions of which are incorporated herein by reference:

          (1)   A Participant's benefits shall be distributed to him not later
                than April 1st of the calendar year following the later of (i)
                the calendar year in which the Participant attains age 70 1/2 or
                (ii) the calendar year in which the Participant retires,
                provided, however, that this clause (ii) shall not apply in the
                case of a Participant who is a "five (5) percent owner" at any
                time during the five (5) Plan Year period ending in the calendar
                year in which he attains age 70 1/2 or, in the case of a
                Participant who becomes a "five (5) percent owner" during any
                subsequent Plan Year, clause (ii) shall no longer apply and the
                required beginning date shall be the April 1st of the calendar
                year following the calendar year in which such subsequent Plan
                Year ends. Alternatively, distributions to a Participant must
                begin no later than the applicable April 1st as determined under
                the preceding sentence and must be made over the life of the
                Participant (or the lives of the Participant and the
                Participant's designated Beneficiary) or, if benefits are paid
                in the form of a Joint and Survivor Annuity, the life expectancy
                of the Participant (or the life expectancies of the Participant
                and his designated Beneficiary) in accordance with Regulations.
                For Plan Years beginning after December 31, 1988, clause (ii)
                above shall not apply to any Participant unless the Participant
                had attained age 70 1/2 before January 1, 1988, and was not a
                "five (5) percent owner" at any time during the Plan Year ending
                with or within the calendar year in which the Participant
                attained age 66 1/2 or any subsequent Plan Year.

          (2)   Distributions to a Participant and his Beneficiaries shall only
                be made in accordance with the incidental death benefit
                requirements of Code Section 401(a)(9)(G) and the Regulations
                thereunder.

                Additionally, for calendar years beginning before 1989,
                distributions may also be made under an alternative method which
                provides that the then present value of the payments to be made
                over the period of the Participant's life expectancy exceeds
                fifty percent (50%) of the then present value of the total
                payments to be made to the Participant and his Beneficiaries.

      (f) For purposes of this Section, the life expectancy of a Participant and
          a Participant's spouse (other than in the case of a life annuity)
          shall be redetermined annually in accordance with Regulations if
          permitted pursuant to the Adoption Agreement. If the Participant or
          the Participant's spouse may elect whether recalculations will be
          made, then the election, once made, shall be irrevocable. If no
          election is made by the time distributions must commence, then the
          life expectancy of the Participant and the Participant's spouse shall
          not be subject to recalculation. Life expectancy and joint and last
          survivor expectancy shall be computed using the return multiples in
          Tables V and VI of Regulation 1.72-9.

                                       58
<PAGE>
 
      (g) All annuity Contracts under this Plan shall be non-transferable when
          distributed. Furthermore, the terms of any annuity Contract purchased
          and distributed to a Participant or spouse shall comply with all of
          the requirements of this Plan.

      (h) Subject to the spouse's right of consent afforded under the Plan, the
          restrictions imposed by this Section shall not apply if a Participant
          has, prior to January 1, 1984, made a written designation to have his
          retirement benefit paid in an alternative method acceptable under Code
          Section 401(a) as in effect prior to the enactment of the Tax Equity
          and Fiscal Responsibility Act of 1982.

      (i) If a distribution is made at a time when a Participant who has not
          terminated employment is not fully Vested in his Participant's Account
          and the Participant may increase the Vested percentage in such
          account:

          (1)   A separate account shall be established for the Participant's
                interest in the Plan as of the time of the distribution, and

          (2)   At any relevant time the Participant's Vested portion of the
                separate account shall be equal to an amount ("X") determined by
                the formula:

                      X equals P(AB plus (RxD)) - (R x D)

          For purposes of applying the formula: P is the Vested percentage at
          the relevant time, AB is the account balance at the relevant time, D
          is the amount of distribution, and R is the ratio of the account
          balance at the relevant time to the account balance after
          distribution.

6.6   DISTRIBUTION OF BENEFITS UPON DEATH

      (a) Unless otherwise elected as provided below, a Vested Participant who
          dies before the annuity starting date and who has a surviving spouse
          shall have the Pre-Retirement Survivor Annuity paid to his surviving
          spouse. The Participant's spouse may direct that payment of the Pre-
          Retirement Survivor Annuity commence within a reasonable period after
          the Participant's death. If the spouse does not so direct, payment of
          such benefit will commence at the time the Participant would have
          attained the later of his Normal Retirement Age or age 62. However,
          the spouse may elect a later commencement date. Any distribution to
          the Participant's spouse shall be subject to the rules specified in
          Section 6.6(h).

      (b) Any election to waive the Pre-Retirement Survivor Annuity before the
          Participant's death must be made by the Participant in writing during
          the election period and shall require the spouse's irrevocable consent
          in the same manner provided for in Section 6.5(a)(2). Further, the
          spouse's consent must acknowledge the specific nonspouse Beneficiary.
          Notwithstanding the foregoing, the nonspouse Beneficiary need not be
          acknowledged, provided the consent of the spouse acknowledges that the
          spouse has the right to limit consent only to a specific Beneficiary
          and that the spouse voluntarily elects to relinquish such right.

                                       59
<PAGE>
 
      (c) The election period to waive the Pre-Retirement Survivor Annuity shall
          begin on the first day of the Plan Year in which the Participant
          attains age 35 and end on the date of the Participant's death. An
          earlier waiver (with spousal consent) may be made provided a written
          explanation of the Pre-Retirement Survivor Annuity is given to the
          Participant and such waiver becomes invalid at the beginning of the
          Plan Year in which the Participant turns age 35. In the event a Vested
          Participant separates from service prior to the beginning of the
          election period, the election period shall begin on the date of such
          separation from service.

      (d) With regard to the election, the Administrator shall provide each
          Participant within the applicable period, with respect to such
          Participant (and consistent with Regulations), a written explanation
          of the Pre-Retirement Survivor Annuity containing comparable
          information to that required pursuant to Section 6.5(a)(6). For the
          purposes of this paragraph, the term "applicable period" means, with
          respect to a Participant, whichever of the following periods ends
          last:

          (1)   The period beginning with the first day of the Plan Year in
                which the Participant attains age 32 and ending with the close
                of the Plan Year preceding the Plan Year in which the
                Participant attains age 35;

          (2)   A reasonable period after the individual becomes a Participant.
                For this purpose, in the case of an individual who becomes a
                Participant after age 32, the explanation must be provided by
                the end of the three-year period beginning with the first day of
                the first Plan Year for which the individual is a Participant;

          (3)   A reasonable period ending after the Plan no longer fully
                subsidizes the cost of the Pre-Retirement Survivor Annuity with
                respect to the Participant;

          (4)   A reasonable period ending after Code Section 401(a)(11) applies
                to the Participant; or

          (5)   A reasonable period after separation from service in the case of
                a Participant who separates before attaining age 35. For this
                purpose, the Administrator must provide the explanation
                beginning one year before the separation from service and ending
                one year after separation.

      (e) The Pre-Retirement Survivor Annuity provided for in this Section shall
          apply only to Participants who are credited with an Hour of Service on
          or after August 23, 1984. Former Participants who are not credited
          with an Hour of Service on or after August 23, 1984 shall be provided
          with rights to the Pre-Retirement Survivor Annuity in accordance with
          Section 303(e)(2) of the Retirement Equity Act of 1984.

      (f) If the value of the Pre-Retirement Survivor Annuity derived from
          Employer and Employee contributions does not exceed $3,500, or such
          lesser amount as specified in the Adoption Agreement, and has never
          exceeded $3,500, or such lesser amount as specified in the Adoption
          Agreement, at the time of any prior distribution, the 

                                       60
<PAGE>
 
          Administrator shall direct the immediate distribution of such amount
          to the Participant's spouse. No distribution may be made under the
          preceding sentence after the annuity starting date unless the spouse
          consents in writing. If the value exceeds, or has ever exceeded at the
          time of any prior distribution, $3,500, or such lesser amount as
          specified in the Adoption Agreement, an immediate distribution of the
          entire amount may be made to the surviving spouse, provided such
          surviving spouse consents in writing to such distribution. Any written
          consent required under this paragraph must be obtained not more than
          90 days before commencement of the distribution and shall be made in a
          manner consistent with Section 6.5(a)(2).

   (g)(1) In the event there is an election to waive the Pre-Retirement Survivor
          Annuity, and for death benefits in excess of the Pre-Retirement
          Survivor Annuity, such death benefits shall be paid to the
          Participant's Beneficiary by either of the following methods, as
          elected by the Participant (or if no election has been made prior to
          the Participant's death, by his Beneficiary) subject to the rules
          specified in Section 6.6(h) and the selections made in the Adoption
          Agreement:

          (i)   One lump sum payment in cash or in property;

          (ii)  One or more partial distributions in cash or in property;

          (iii) Payment in monthly, quarterly, semi-annual, or annual cash
                installments over a period to be determined by the Participant
                or his Beneficiary. After periodic installments commence, the
                Beneficiary shall have the right to reduce the period over which
                such periodic installments shall be made, and the cash amount of
                such periodic installments shall be adjusted accordingly.

          (iv)  If death benefits in excess of the Pre-Retirement Survivor
                Annuity are to be paid to the surviving spouse, such benefits
                may be paid pursuant to (i), (ii), or (iii) above, or used to
                purchase an annuity so as to increase the payments made pursuant
                to the Pre-Retirement Survivor Annuity;

      (2) In the event the death benefit payable pursuant to Section 6.2 is
          payable in installments, then, upon the death of the Participant, the
          Administrator may direct that the death benefit be segregated and
          invested separately, and that the funds accumulated in the segregated
          account be used for the payment of the installments.

   (h)    Notwithstanding any provision in the Plan to the contrary,
          distributions upon the death of a Participant made on or after January
          1, 1985, shall be made in accordance with the following requirements
          and shall otherwise comply with Code Section 401(a)(9) and the
          Regulations thereunder.

          (1)   If it is determined, pursuant to Regulations, that the
                distribution of a Participant's interest has begun and the
                Participant dies before his entire interest has been distributed
                to him, the remaining portion of such interest shall be
                distributed at least as rapidly as under the method of
                distribution selected pursuant to Section 6.5 as of his date of
                death.

                                       61
<PAGE>
 
          (2)   If a Participant dies before he has begun to receive any
                distributions of his interest in the Plan or before
                distributions are deemed to have begun pursuant to Regulations,
                then his death benefit shall be distributed to his Beneficiaries
                in accordance with the following rules subject to the selections
                made in the Adoption Agreement and Subsections 6.6(h)(3) and
                6.6(i) below:

                (i)  The entire death benefit shall be distributed to the
                     Participant's Beneficiaries by December 31st of the
                     calendar year in which the fifth anniversary of the
                     Participant's death occurs;

                (ii) The 5-year distribution requirement of (i) above shall not
                     apply to any portion of the deceased Participant's interest
                     which is payable to or for the benefit of a designated
                     Beneficiary. In such event, such portion shall be
                     distributed over the life of such designated Beneficiary
                     (or over a period not extending beyond the life expectancy
                     of such designated Beneficiary) provided such distribution
                     begins not later than December 31st of the calendar year
                     immediately following the calendar year in which the
                     Participant died;

               (iii) However, in the event the Participant's spouse (determined
                     as of the date of the Participant's death) is his
                     designated Beneficiary, the provisions of (ii) above shall
                     apply except that the requirement that distributions
                     commence within one year of the Participant's death shall
                     not apply. In lieu thereof, distributions must commence on
                     or before the later of: (1) December 31st of the calendar
                     year immediately following the calendar year in which the
                     Participant died; or (2) December 31st of the calendar year
                     in which the Participant would have attained age 70 1/2. If
                     the surviving spouse dies before distributions to such
                     spouse begin, then the 5-year distribution requirement of
                     this Section shall apply as if the spouse was the
                     Participant.

                For purposes of Section 6.5(h)(2) above, if the surviving spouse
                dies after the Participant, but before any payments to such
                spouse begin, the provisions of this section, with the exception
                of paragraph (ii) therein, shall be applied as if the surviving
                spouse were the Participant.

          (3)   Notwithstanding subparagraph (2) above, or any selections made
                in the Adoption Agreement, if a Participant's death benefits are
                to be paid in the form of a Pre-Retirement Survivor Annuity,
                then distributions to the Participant's surviving spouse must
                commence on or before the later of: (1) December 31st of the
                calendar year immediately following the calendar year in which
                the Participant died; or (2) December 31st of the calendar year
                in which the Participant would have attained age 70 1/2.

                                       62
<PAGE>
 
      (i) For purposes of Section 6.6(h)(2), the election by a designated
          Beneficiary to be excepted from the 5-year distribution requirement
          (if permitted in the Adoption Agreement) must be made no later than
          December 31st of the calendar year following the calendar year of the
          Participant's death. Except, however, with respect to a designated
          Beneficiary who is the Participant's surviving spouse, the election
          must be made by the earlier of: (1) December 31st of the calendar year
          immediately following the calendar year in which the Participant died
          or, if later, the calendar year in which the Participant would have
          attained age 70 1/2; or (2) December 31st of the calendar year which
          contains the fifth anniversary of the date of the Participant's death.
          An election by a designated Beneficiary must be in writing and shall
          be irrevocable as of the last day of the election period stated
          herein. In the absence of an election by the Participant or a
          designated Beneficiary, the 5-year distribution requirement shall
          apply.

      (j) For purposes of this Section, the life expectancy of a Participant and
          a Participant's spouse (other than in the case of a life annuity)
          shall or shall not be redetermined annually as provided in the
          Adoption Agreement and in accordance with Regulations. If the
          Participant or the Participant's spouse may elect, pursuant to the
          Adoption Agreement, to have life expectancies recalculated, then the
          election, once made shall be irrevocable. If no election is made by
          the time distributions must commence, then the life expectancy of the
          Participant and the Participant's spouse shall not be subject to
          recalculation. Life expectancy and joint and last survivor expectancy
          shall be computed using the return multiples in Tables V and VI of
          Regulation Section 1.72-9.

      (k) In the event that less than 100% of a Participant's interest in the
          Plan is distributed to such Participant's spouse, the portion of the
          distribution attributable to the Participant's Voluntary Contribution
          Account shall be in the same proportion that the Participant's
          Voluntary Contribution Account bears to the Participant's total
          interest in the Plan.

      (l) Subject to the spouse's right of consent afforded under the Plan, the
          restrictions imposed by this Section shall not apply if a Participant
          has, prior to January 1, 1984, made a written designation to have his
          death benefits paid in an alternative method acceptable under Code
          Section 401(a) as in effect prior to the enactment of the Tax Equity
          and Fiscal Responsibility Act of 1982.

6.7   TIME OF SEGREGATION OR DISTRIBUTION

      Except as limited by Sections 6.5 and 6.6, whenever a distribution is to
      be made, or a series of payments are to commence, on or as of an
      Anniversary Date, the distribution or series of payments may be made or
      begun on such date or as soon thereafter as is practicable, but in no
      event later than 180 days after the Anniversary Date. However, unless a
      Former Participant elects in writing to defer the receipt of benefits
      (such election may not result in a death benefit that is more than
      incidental), the payment of benefits shall begin not later than the 60th
      day after the close of the Plan Year in which the latest of the following
      events occurs: (a) the date on which the Participant attains the earlier
      of age 65 or the Normal Retirement Age specified herein; (b) the 10th
      anniversary of the year in which the Participant commenced participation
      in the Plan; or (c) the date the Participant terminates his service with
      the Employer.

                                       63
<PAGE>
 
      Notwithstanding the foregoing, the failure of a Participant and, if
      applicable, the Participant's spouse, to consent to a distribution
      pursuant to Section 6.5(d), shall be deemed to be an election to defer the
      commencement of payment of any benefit sufficient to satisfy this Section.

6.8   DISTRIBUTION FOR MINOR BENEFICIARY

      In the event a distribution is to be made to a minor, then the
      Administrator may direct that such distribution be paid to the legal
      guardian, or if none, to a parent of such Beneficiary or a responsible
      adult with whom the Beneficiary maintains his residence, or to the
      custodian for such Beneficiary under the Uniform Gift to Minors Act or
      Gift to Minors Act, if such is permitted by the laws of the state in which
      said Beneficiary resides. Such a payment to the legal guardian, custodian
      or parent of a minor Beneficiary shall fully discharge the Trustee,
      Employer, and Plan from further liability on account thereof.

6.9   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 later of the
      Participant's attainment of age 62 or his Normal Retirement Age, remain
      unpaid solely by reason of the inability of the Administrator, after
      sending a registered letter, return receipt 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 treated as a Forfeiture pursuant to the Plan. In the event a
      Participant or Beneficiary is located subsequent to his benefit being
      reallocated, such benefit shall be restored, first from Forfeitures, if
      any, and then from an additional Employer contribution if necessary.

6.10  PRE-RETIREMENT DISTRIBUTION     

      For Profit Sharing Plans and 401(k) Profit Sharing Plans, if elected in
      the Adoption Agreement, at such time as a Participant shall have attained
      the age specified in the Adoption Agreement, the Administrator, at the
      election of the Participant, shall direct the distribution of up to 100%
      of his Vested accounts, as specified in the Adoption Agreement, valued as
      of the last Anniversary Date or other valuation date. However, no such
      distribution from the Participant's Account shall occur prior to 100%
      Vesting. In the event that the Administrator makes such a distribution,
      the Participant shall continue to be eligible to participate in the Plan
      on the same basis as any other Employee. Any distribution made pursuant to
      this Section shall be made in a manner consistent with Section 6.5,
      including, but not limited to, all notice and consent requirements of Code
      Sections 411(a)(11) and 417 and the Regulations thereunder.

                                       64

6.11  ADVANCE DISTRIBUTION FOR HARDSHIP

      (a) For Profit Sharing Plans, the Administrator, at the election of the
          Participant, shall direct the distribution to any Participant in any
          one Plan Year up to the lesser of 100% of his Vested accounts, as
          specified in the Adoption Agreement, valued as of the last Anniversary
          Date or other valuation date or the amount necessary to satisfy the
          immediate and heavy financial need of the Participant. Such amount of
          an immediate and heavy financial need may include any amounts
          necessary to pay any federal, state, or local income taxes or
          penalties reasonably anticipated to result from the distribution. Any
          distribution made pursuant to this Section shall be deemed to be made
          as of the first day of the Plan Year or, if later, the valuation date
          immediately preceding the date of distribution, and the account from
          which the distribution is made shall be reduced accordingly.
          Withdrawal under this Section shall be authorized only if the
          distribution is on account of:

          (1)   Expenses for medical care described in Code Section 213(d)
                previously incurred by the Participant, his spouse, or any of
                his dependents (as defined in Code Section 152) or necessary for
                those persons to obtain medical care as described in Code
                Section 213(d);

          (2)   Costs directly related to the purchase (excluding mortgage
                payments) of a principal residence for the Participant;

          (3)   Funeral expenses for a member of the Participant's family;

          (4)   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

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

      (b) Distributions may be made from the Participant's Vested accounts.

      (c) Any distribution made pursuant to this Section shall be made in a
          manner which is consistent with and satisfies the provisions of
          Section 6.5, including, but not limited to, all notice and consent
          requirements of Code Sections 411(a)(11) and 417 and the Regulations
          thereunder.

6.12  LIMITATIONS ON BENEFITS AND DISTRIBUTIONS

      All rights and benefits, including elections, provided to a Participant in
      this Plan shall be subject to the rights afforded to any "alternate payee"
      under a "qualified domestic relations order." Furthermore, a distribution
      to an "alternate payee" shall be permitted if such distribution is
      authorized by a "qualified domestic relations order," even if the affected
      Participant has not reached the "earliest retirement age" under the Plan.
      For the purposes of this Section, "alternate payee," "qualified domestic
      relations order" and "earliest retirement age" shall have the meaning set
      forth under Code Section 414(p).

6.13  SPECIAL RULE FOR NON-ANNUITY PLANS     

      If elected in the Adoption Agreement, the following shall apply to a
      Participant in a Profit Sharing Plan or 401(k) Profit Sharing Plan and to
      any distribution, made on or after the first day of the first plan year
      beginning after December 31, 1988, from or under a separate account
      attributable solely to accumulated deductible employee contributions, as
      defined in Code Section 72(o)(5)(B), and maintained on behalf of a
      participant in a money purchase pension plan, (including a target benefit
      plan):

      (a) Under this Section 6.13, the automatic form of distribution is a lump
          sum. If specified in the Adoption Agreement, the Participant may elect
          an annuity as an optional form of distribution, in which case the
          Joint and Survivor Annuity rules will apply.

      (b) Upon the death of the Participant, the Participant's entire Vested
          account balances will be paid to his or her surviving spouse, or, if
          there is no surviving spouse or the surviving spouse has already
          consented to waive his or her benefit, in accordance with Section 6.6,
          to his designated Beneficiary;

      (c) If a distribution is one to which Code Sections 401(a)(11) and 417 do
          not apply, such distribution may commence less than 30 days after the
          notice required under Regulation Section 1.411(a)-11(c) is given,
          provided that:

          (1)   the Plan Administrator clearly informs the Participant that the
                Participant has a right to a period of at least 30 days after
                receiving the notice to consider the decision of whether or not
                to elect a distribution (and, if applicable, a particular
                distribution option), and

          (2)   the Participant, after receiving the notice, affirmatively
                elects a distribution.

      (d) Except to the extent otherwise provided in this Section and Section
          6.5(h), the other provisions of Sections 6.2, 6.5 and 6.6 regarding
          spousal consent and the forms of distributions shall be inoperative
          with respect to this Plan.

          This Section shall not apply to any Participant if it is determined
          that this Plan is a direct or indirect transferee of a defined benefit
          plan or money purchase plan, or a target benefit plan, stock bonus or
          profit sharing plan which would otherwise provide for a life annuity
          form of payment to the Participant.

                                  ARTICLE VII
                                    TRUSTEE

7.1   BASIC RESPONSIBILITIES OF THE TRUSTEE

      The Trustee shall have the following categories of responsibilities.
      However, if elected in the Adoption Agreement, a separate trust document
      shall apply in lieu of this Article VII. Moreover, if the Plan's assets
      are invested solely in group annuity contracts and there is no separate
      trust document, then, if elected in the Adoption Agreement, the terms of
      the group annuity contract(s) shall apply in lieu of this Article.

      (a) Consistent with the "funding policy and method" determined by the
          Employer to invest, manage, and control the Plan assets subject,
          however, to the direction of an Investment Manager if the Employer
          should appoint such manager as to all or a portion of the assets of
          the Plan;

      (b) At the direction of the Administrator, to pay benefits required under
          the Plan to be paid to Participants, or, in the event of their death,
          to their Beneficiaries;

      (c) To maintain records of receipts and disbursements and furnish to the
          Employer and/or Administrator for each Plan Year a written annual
          report per Section 7.7; and

      (d) If there shall be more than one Trustee, they shall act by a majority
          of their number, but may authorize one or more of them to sign papers
          on their behalf.

7.2   INVESTMENT POWERS AND DUTIES OF THE TRUSTEE

      (a) The Trustee shall invest and reinvest the Trust Fund to keep the Trust
          Fund invested without distinction between principal and income and in
          such securities or property, real or personal, wherever situated, as
          the Trustee shall deem advisable, including, but not limited to,
          mutual funds, stocks, common or preferred, bonds and other evidences
          of indebtedness or ownership, and real estate or any interest therein.
          The Trustee shall at all times in making investments of the Trust Fund
          consider, among other factors, the short and long-term financial needs
          of the Plan on the basis of information furnished by the Employer. In
          making such investments, the Trustee shall not be restricted to
          securities or other property of the character expressly authorized by
          the applicable law for trust investments; however, the Trustee shall
          give due regard to any limitations imposed by the Code or the Act so
          that at all times this Plan may qualify as a qualified Plan and Trust.

      (b) The Trustee may employ a bank or trust company pursuant to the terms
          of its usual and customary bank agency agreement, under which the
          duties of such bank or trust company shall be of a custodial, clerical
          and record-keeping nature.

      (c) The Trustee may from time to time transfer to a common, collective, or
          pooled trust fund maintained by any corporate Trustee hereunder
          pursuant to Revenue Ruling 81-100, all or such part of the Trust Fund
          as the Trustee may deem advisable, and such part or all of 

                                       67
<PAGE>
 
          the Trust Fund so transferred shall be subject to all the terms and
          provisions of the common, collective, or pooled trust fund which
          contemplate the commingling for investment purposes of such trust
          assets with trust assets of other trusts. The Trustee may withdraw
          from such common, collective, or pooled trust fund all or such part of
          the Trust Fund as the Trustee may deem advisable.

      (d) The Trustee, at the direction of the Administrator and pursuant to
          instructions from the individual designated in the Adoption Agreement
          for such purpose and subject to the conditions set forth in the
          Adoption Agreement, shall ratably apply for, own, and pay all premiums
          on Contracts on the lives of the Participants. Any initial or
          additional Contract purchased on behalf of a Participant shall have a
          face amount of not less than $1,000, the amount set forth in the
          Adoption Agreement, or the limitation of the Insurer, whichever is
          greater. If a life insurance Contract is to be purchased for a
          Participant, the aggregate premium for ordinary life insurance for
          each Participant must be less than 50% of the aggregate contributions
          and Forfeitures allocated to a Participant's Combined Account. For
          purposes of this limitation, ordinary life insurance Contracts are
          Contracts with both non-decreasing death benefits and non-increasing
          premiums. If term insurance or universal life insurance is purchased
          with such contributions, the aggregate premium must be 25% or less of
          the aggregate contributions and Forfeitures allocated to a
          Participant's Combined Account. If both term insurance and ordinary
          life insurance are purchased with such contributions, the amount
          expended for term insurance plus one-half of the premium for ordinary
          life insurance may not in the aggregate exceed 25% of the aggregate
          Employer contributions and Forfeitures allocated to a Participant's
          Combined Account. The Trustee must distribute the Contracts to the
          Participant or convert the entire value of the Contracts at or before
          retirement into cash or provide for a periodic income so that no
          portion of such value may be used to continue life insurance
          protection beyond retirement. Notwithstanding the above, the
          limitations imposed herein with respect to the purchase of life
          insurance shall not apply, in the case of a Profit Sharing Plan, to
          the portion of a Participant's Account that has accumulated for at
          least two (2) Plan Years.

          Notwithstanding anything hereinabove to the contrary, amounts credited
          to a Participant's Qualified Voluntary Employee Contribution Account
          pursuant to Section 4.9, shall not be applied to the purchase of life
          insurance contracts.

      (e) The Trustee will be the owner of any life insurance Contract purchased
          under the terms of this Plan. The Contract must provide that the
          proceeds will be payable to the Trustee; however, the Trustee shall be
          required to pay over all proceeds of the Contract to the Participant's
          designated Beneficiary in accordance with the distribution provisions
          of Article VI. A Participant's spouse will be the designated
          Beneficiary pursuant to Section 6.2, unless a qualified election has
          been made in accordance with Sections 6.5 and 6.6 of the Plan, if
          applicable. Under no circumstances shall the Trust retain any part of
          the proceeds. However, the Trustee shall not pay the proceeds in a
          method that would violate the requirements of the Retirement Equity
          Act, as stated in Article VI of the Plan, or Code Section 401(a)(9)
          and the Regulations thereunder. In the event of any conflict between
          the terms of this Prototype Plan and the terms of any insurance
          Contract(s) purchased hereunder, the Prototype Plan provisions shall
          control.

                                       68
<PAGE>
 
      (f) Notwithstanding anything in this Section 7.2, if this Plan is used in
          conjunction with a separate trust, the separate trust shall control
          with respect to the powers and duties of the Trustee.

7.3   OTHER POWERS OF THE TRUSTEE

      The Trustee, in addition to all powers and authorities under common law,
      statutory authority, including the Act, and other provisions of this Plan,
      shall have the following powers and authorities to be exercised in the
      Trustee's sole discretion:

          advertisement;

          to oppose, or 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;

      (d) To cause any securities or other property to be registered in the
          Trustee's own name or in the name of one or more of the Trustee's
          nominees, and to hold any investments in bearer form, but the books
          and records of the Trustee shall at all times show that all such
          investments are part of the Trust Fund;

      (e) To borrow or raise money for the purposes of the Plan in such amount,
          and upon such terms and conditions, as the Trustee shall deem
          advisable; and for any sum so borrowed, to issue a promissory note as
          Trustee, and to secure the repayment thereof by pledging all, or any
          part, of the Trust Fund; and no person lending money to the Trustee
          shall be bound to see to the application of the money lent or to
          inquire into the validity, expediency, or propriety of any borrowing;

      (f) To keep such portion of the Trust Fund in cash or cash balances as the
          Trustee may, from time to time, deem to be in the best interests of
          the Plan, without liability for interest thereon;

                                       69
<PAGE>
 
      (g) To accept and retain for such time as it may deem advisable any
          securities or other property received or acquired by it as Trustee
          hereunder, whether or not such securities or other property would
          normally be purchased as investments hereunder;

      (h) To make, execute, acknowledge, 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;

      (i) To settle, compromise, or submit to arbitration any claims, debts, or
          damages due or owing to or from the Plan, to commence or defend suits
          or legal or administrative proceedings, and to represent the Plan in
          all suits and legal and administrative proceedings;

      (j) To employ suitable agents and counsel and to pay their reasonable
          expenses and compensation, and such agent or counsel may or may not be
          agent or counsel for the Employer;

      (k) To apply for and procure from the Insurer as an investment of the
          Trust Fund such annuity, or other Contracts (on the life of any
          Participant) as the Administrator shall deem proper; to exercise, at
          any time or from time to time, whatever rights and privileges may be
          granted under such annuity, or other Contracts; to collect, receive,
          and settle for the proceeds of all such annuity, or other Contracts as
          and when entitled to do so under the provisions thereof;

      (l) To invest funds of the Trust in time deposits or savings accounts
          bearing a reasonable rate of interest in the Trustee's bank;

      (m) To invest in Treasury Bills and other forms of United States
          government obligations;

      (n) To sell, purchase and acquire put or call options if the options are
          traded on and purchased through a national securities exchange
          registered under the Securities Exchange Act of 1934, as amended, or,
          if the options are not traded on a national securities exchange, are
          guaranteed by a member firm of the New York Stock Exchange;

      (o) To deposit monies in federally insured savings accounts or
          certificates of deposit in banks or savings and loan associations;

      (p) To pool all or any of the Trust Fund, from time to time, with assets
          belonging to any other qualified employee pension benefit trust
          created by the Employer or any Affiliated Employer, and to commingle
          such assets and make joint or common investments and carry joint
          accounts on behalf of this Plan and such other trust or trusts,
          allocating undivided shares or interests in such investments or
          accounts or any pooled assets of the two or more trusts in accordance
          with their respective interests;

      (q) To do all such acts and exercise all such rights and privileges,
          although not specifically mentioned herein, as the Trustee may deem
          necessary to carry out the purposes of the Plan.

                                       70
<PAGE>
 
      (r) Directed Investment Account. The powers granted to the Trustee shall
          be exercised in the sole fiduciary discretion of the Trustee. However,
          if elected in the Adoption Agreement, each Participant may direct the
          Trustee to separate and keep separate all or a portion of his interest
          in the Plan; and further each Participant is authorized and empowered,
          in his sole and absolute discretion, to give directions to the Trustee
          in such form as the Trustee may require concerning the investment of
          the Participant's Directed Investment Account, which directions must
          be followed by the Trustee subject, however, to restrictions on
          payment of life insurance premiums. Neither the Trustee nor any other
          persons including the Administrator or otherwise shall be under any
          duty to question any such direction of the Participant or to review
          any securities or other property, real or personal, or to make any
          suggestions to the Participant in connection therewith, and the
          Trustee shall comply as promptly as practicable with directions given
          by the Participant hereunder. Any such direction may be of a
          continuing nature or otherwise and may be revoked by the Participant
          at any time in such form as the Trustee may require. The Trustee may
          refuse to comply with any direction from the Participant in the event
          the Trustee, in its sole and absolute discretion, deems such
          directions improper by virtue of applicable law, and in such event,
          the Trustee shall not be responsible or liable for any loss or expense
          which may result. Any costs and expenses related to compliance with
          the Participant's directions shall be borne by the Participant's
          Directed Investment Account.

          Notwithstanding anything hereinabove to the contrary, the Trustee
          shall not, at any time after December 31, 1981, invest any portion of
          a Directed Investment Account in "collectibles" within the meaning of
          that term as employed in Code Section 408(m).

7.4   LOANS TO PARTICIPANTS

      (a) If specified in the Adoption Agreement, the Trustee (or, if loans are
          treated as Directed Investment pursuant to the Adoption Agreement, the
          Administrator) may, in the Trustee's (or, if applicable, the
          Administrator's) sole discretion, make loans to Participants or
          Beneficiaries under the following circumstances: (1) loans shall be
          made available to all Participants and Beneficiaries on a reasonably
          equivalent basis; (2) loans shall not be made available to Highly
          Compensated Employees in an amount greater than the amount made
          available to other Participants; (3) loans shall bear a reasonable
          rate of interest; (4) loans shall be adequately secured; and (5) shall
          provide for periodic repayment over a reasonable period of time.

      (b) Loans shall not be made to any Shareholder-Employee or Owner-Employee
          unless an exemption for such loan is obtained pursuant to Act Section
          408 and further provided that such loan would not be subject to tax
          pursuant to Code Section 4975.

      (c) Loans shall not be granted to any Participant that provide for a
          repayment period extending beyond such Participant's Normal Retirement
          Date.

      (d) Loans made pursuant to this Section (when added to the outstanding
          balance of all other loans made by the Plan to the Participant) shall
          be limited to the lesser of:

                                       71
<PAGE>
 
          (1)   $50,000 reduced by the excess (if any) of the highest
                outstanding balance of loans from the Plan to the Participant
                during the one year period ending on the day before the date on
                which such loan is made, over the outstanding balance of loans
                from the Plan to the Participant on the date on which such loan
                was made, or

          (2)   the greater of (A) one-half (1/2) of the present value of the
                non-forfeitable accrued benefit of the Employee under the Plan,
                or (B), if permitted pursuant to the Adoption Agreement,
                $10,000.

          For purposes of this limit, all plans of the Employer shall be
          considered one plan. Additionally, with respect to any loan made prior
          to January 1, 1987, the $50,000 limit specified in (1) above shall be
          unreduced.

      (e) No Participant loan shall take into account the present value of such
          Participant's Qualified Voluntary Employee Contribution Account.

      (f) Loans shall provide for level amortization with payments to be made
          not less frequently than quarterly over a period not to exceed five
          (5) years. However, loans used to acquire any dwelling unit which,
          within a reasonable time, is to be used (determined at the time the
          loan is made) as a principal residence of the Participant shall
          provide for periodic repayment over a reasonable period of time that
          may exceed five (5) years. Notwithstanding the foregoing, loans made
          prior to January 1, 1987 which are used to acquire, construct,
          reconstruct or substantially rehabilitate any dwelling unit which,
          within a reasonable period of time is to be used (determined at the
          time the loan is made) as a principal residence of the Participant or
          a member of his family (within the meaning of Code Section 267(c)(4))
          may provide for periodic repayment over a reasonable period of time
          that may exceed five (5) years. Additionally, loans made prior to
          January 1, 1987, may provide for periodic payments which are made less
          frequently than quarterly and which do not necessarily result in level
          amortization.

      (g) An assignment or pledge of any portion of a Participant's interest in
          the Plan and a loan, pledge, or assignment with respect to any
          insurance Contract purchased under the Plan, shall be treated as a
          loan under this Section.

      (h) Any loan made pursuant to this Section after August 18, 1985 where the
          Vested interest of the Participant is used to secure such loan shall
          require the written consent of the Participant's spouse in a manner
          consistent with Section 6.5(a) provided the spousal consent
          requirements of such Section apply to the Plan. Such written consent
          must be obtained within the 90-day period prior to the date the loan
          is made. Any security interest held by the Plan by reason of an
          outstanding loan to the Participant shall be taken into account in
          determining the amount of the death benefit or Pre-Retirement Survivor
          Annuity. However, no spousal consent shall be required under this
          paragraph if the total accrued benefit subject to the security is not
          in excess of $3,500.

                                       72
<PAGE>
 
      (i) With regard to any loans granted or renewed on or after the last day
          of the first Plan Year beginning after December 31, 1988, a
          Participant loan program shall be established which must include, but
          need not be limited to, the following:

          (1)   the identity of the person or positions authorized to administer
                the Participant loan program;

          (2)   a procedure for applying for loans;

          (3)   the basis on which loans will be approved or denied;

          (4)   limitations, if any, on the types and amounts of loans offered,
                including what constitutes a hardship or financial need if
                selected in the Adoption Agreement;

          (5)   the procedure under the program for determining a reasonable
                rate of interest;

          (6)   the types of collateral which may secure a Participant loan; and

          (7)   the events constituting default and the steps that will be taken
                to preserve plan assets.

          Such Participant loan program shall be contained in a separate written
          document which, when properly executed, is hereby incorporated by
          reference and made a part of this plan. Furthermore, such Participant
          loan program may be modified or amended in writing from time to time
          without the necessity of amending this Section of the Plan.

7.5   DUTIES OF THE TRUSTEE REGARDING PAYMENTS

      At the direction of the Administrator, the Trustee shall, from time to
      time, in accordance with the terms of the Plan, make payments out of the
      Trust Fund. The Trustee shall not be responsible in any way for the
      application of such payments.

7.6   TRUSTEE'S COMPENSATION AND EXPENSES AND TAXES

      The Trustee shall be paid such reasonable compensation as set forth in the
      Trustee's fee schedule (if the Trustee has such a schedule) or as agreed
      upon in writing by the Employer and the Trustee. An individual serving as
      Trustee who already receives full-time pay from the Employer shall not
      receive compensation from this Plan. In addition, the Trustee shall be
      reimbursed for any reasonable expenses, including reasonable counsel fees
      incurred by it as Trustee. Such compensation and expenses shall be paid
      from the Trust Fund unless paid or advanced by the Employer. All taxes of
      any kind and all kinds whatsoever that may be levied or assessed under
      existing or future laws upon, or in respect of, the Trust Fund or the
      income thereof, shall be paid from the Trust Fund.

                                       73
<PAGE>
 
7.7   ANNUAL REPORT OF THE TRUSTEE

      Within a reasonable period of time after the later of the Anniversary Date
      or receipt of the Employer's contribution for each Plan Year, the Trustee,
      or its agent, shall furnish to the Employer and Administrator a written
      statement of account with respect to the Plan Year for which such
      contribution was made setting forth:

      (a) the net income, or loss, of the Trust Fund;

      (b) the gains, or losses, realized by the Trust Fund upon sales or other
          disposition of the assets;

      (c) the increase, or decrease, in the value of the Trust Fund;

      (d) all payments and distributions made from the Trust Fund; and

      (e) such further information as the Trustee and/or Administrator deems
          appropriate. The Employer, forthwith upon its receipt of each such
          statement of account, shall acknowledge receipt thereof in writing and
          advise the Trustee and/or Administrator of its approval or disapproval
          thereof. Failure by the Employer to disapprove any such statement of
          account within thirty (30) days after its receipt thereof shall be
          deemed an approval thereof. The approval by the Employer of any
          statement of account shall be binding as to all matters embraced
          therein as between the Employer and the Trustee to the same extent as
          if the account of the Trustee had been settled by judgment or decree
          in an action for a judicial settlement of its account in a court of
          competent jurisdiction in which the Trustee, the Employer and all
          persons having or claiming an interest in the Plan were parties;
          provided, however, that nothing herein contained shall deprive the
          Trustee of its right to have its accounts judicially settled if the
          Trustee so desires.

7.8   AUDIT

      (a) If an audit of the Plan's records shall be required by the Act and the
          regulations thereunder for any Plan Year, the Administrator shall
          direct the Trustee to engage on behalf of all Participants an
          independent qualified public accountant for that purpose. Such
          accountant shall, after an audit of the books and records of the Plan
          in accordance with generally accepted auditing standards, within a
          reasonable period after the close of the Plan Year, furnish to the
          Administrator and the Trustee a report of his audit setting forth his
          opinion as to whether any statements, schedules or lists, that are
          required by Act Section 103 or the Secretary of Labor to be filed with
          the Plan's annual report, are presented fairly in conformity with
          generally accepted accounting principles applied consistently.

      (b) All auditing and accounting fees shall be an expense of and may, at
          the election of the Administrator, be paid from the Trust Fund.

      (c) If some or all of the information necessary to enable the
          Administrator to comply with Act Section 103 is maintained by a bank,
          insurance company, or similar institution, 

                                       74
<PAGE>
 
          regulated and supervised and subject to periodic examination by a
          state or federal agency, it shall transmit and certify the accuracy of
          that information to the Administrator as provided in Act Section
          103(b) within one hundred twenty (120) days after the end of the Plan
          Year or such other date as may be prescribed under regulations of the
          Secretary of Labor.

7.9   RESIGNATION, REMOVAL AND SUCCESSION OF TRUSTEE

      (a) The Trustee may resign at any time by delivering to the Employer, at
          least thirty (30) days before its effective date, a written notice of
          his resignation.

      (b) The Employer may remove the Trustee by mailing by registered or
          certified mail, addressed to such Trustee at his last known address,
          at least thirty (30) days before its effective date, a written notice
          of his removal.

      (c) Upon the death, resignation, incapacity, or removal of any Trustee, a
          successor may be appointed by the Employer; and such successor, upon
          accepting such appointment in writing and delivering same to the
          Employer, shall, without further act, become vested with all the
          estate, rights, powers, discretions, and duties of his predecessor
          with like respect as if he were originally named as a Trustee herein.
          Until such a successor is appointed, the remaining Trustee or Trustees
          shall have full authority to act under the terms of the Plan.

      (d) The Employer may designate one or more successors prior to the death,
          resignation, incapacity, or removal of a Trustee. In the event a
          successor is so designated by the Employer and accepts such
          designation, the successor shall, without further act, become vested
          with all the estate, rights, powers, discretions, and duties of his
          predecessor with the like effect as if he were originally named as
          Trustee herein immediately upon the death, resignation, incapacity, or
          removal of his predecessor.

      (e) Whenever any Trustee hereunder ceases to serve as such, he shall
          furnish to the Employer and Administrator a written statement of
          account with respect to the portion of the Plan Year during which he
          served as Trustee. This statement shall be either (i) included as part
          of the annual statement of account for the Plan Year required under
          Section 7.7 or (ii) set forth in a special statement. Any such special
          statement of account should be rendered to the Employer no later than
          the due date of the annual statement of account for the Plan Year. The
          procedures set forth in Section 7.7 for the approval by the Employer
          of annual statements of account shall apply to any special statement
          of account rendered hereunder and approval by the Employer of any such
          special statement in the manner provided in Section 7.7 shall have the
          same effect upon the statement as the Employer's approval of an annual
          statement of account. No successor to the Trustee shall have any duty
          or responsibility to investigate the acts or transactions of any
          predecessor who has rendered all statements of account required by
          Section 7.7 and this subparagraph.

7.10  TRANSFER OF INTEREST

      Notwithstanding any other provision contained in this Plan, the Trustee at
      the direction of the Administrator shall transfer the Vested interest, if
      any, of such Participant in his account to another trust forming part of a
      pension, profit sharing, or stock bonus plan maintained by such
      Participant's new employer and represented by said employer in writing as
      meeting the requirements of Code Section 401(a), provided that the trust
      to which such transfers are made permits the transfer to be made.

      Notwithstanding the above, with respect to distributions made after
      December 31, 1992, if the distributee of any "eligible rollover
      distribution" (as defined in Code Section 402(f)(2)(A))(1)) elects to have
      such distribution paid directly to an "eligible retirement plan", and (2)
      specifies the "eligible retirement plan" to which such distribution is to
      be paid (in such form and at such time as the Administrator may
      prescribe), then the distribution shall made in the form of a direct
      trustee-to-trustee transfer and shall be limited to the amount of the
      distribution that would be includible in gross income if not transferred
      in accordance with the preceding (determined without regard to Code
      Sections 402(c) and 403(a)(4)).

      For purposes of this section, the term "eligible retirement plan" has the
      meaning given such term by Code Section 402(c)(8)(B), except that a
      qualified trust shall be considered an eligible retirement plan only if it
      is a defined contribution plan, the terms of which permit the acceptance
      of rollover distributions.

7.11  TRUSTEE INDEMNIFICATION

      The Employer agrees to indemnify and save harmless the Trustee against any
      and all claims, losses, damages, expenses and liabilities the Trustee may
      incur in the exercise and performance of the Trustee's powers and duties
      hereunder, unless the same are determined to be due to gross negligence or
      willful misconduct.

7.12  EMPLOYER SECURITIES AND REAL PROPERTY

      The Trustee shall be empowered to acquire and hold "qualifying Employer
      securities" and "qualifying Employer real property," as those terms are
      defined in the Act. However, no more than 100%, in the case of a Profit
      Sharing Plan or 401(k) Plan, or 10%, in the case of a Money Purchase Plan,
      of the fair market value of all the assets in the Trust Fund may be
      invested in "qualifying Employer securities" and "qualifying Employer real
      property".

                                 ARTICLE VIII
                      AMENDMENT, TERMINATION, AND MERGERS

8.1   AMENDMENT

      (a) The Employer shall have the right at any time to amend this Plan
          subject to the limitations of this Section. Any such amendment shall
          be adopted by formal action of the Employer's board of directors and
          executed by an officer if the Employer is a corporation, partners of
          the Employer and executed by such if the Employer is a partner, owner
          of the Employer and executed by such person or an Employee if the
          Employer is a sole proprietor. However, any amendment which affects
          the rights, duties or responsibilities of the Trustee and
          Administrator may only be made with the Trustee's and Administrator's
          written consent. Any such amendment shall become effective as provided
          therein upon its execution. The Trustee shall not be required to
          execute any such amendment unless the amendment affects the duties of
          the Trustee hereunder.

      (b) The Employer may (1) change the choice of options in the Adoption
          Agreement, (2) add overriding language in the Adoption Agreement when
          such language is necessary to satisfy Code Sections 415 or 416 because
          of the required aggregation of multiple plans, and (3) add certain
          model amendments published by the Internal Revenue Service which
          specifically provide that their adoption will not cause the Plan to be
          treated as an individually designed plan. An Employer that amends the
          Plan for any other reason, including a waiver of the minimum funding
          requirement under Code Section 412(d), will no longer participate in
          this Prototype Plan and will be considered to have an individually
          designed plan.

      (c) The Employer expressly delegates authority to the sponsoring
          organization of this Plan, the right to amend this Plan by submitting
          a copy of the amendment to each Employer who has adopted this Plan
          after first having received a ruling or favorable determination from
          the Internal Revenue Service that the Plan as amended qualifies under
          Code Section 401(a) and the Act. For purposes of this Section, the
          mass submitter shall be recognized as the agent of the sponsoring
          organization. If the sponsoring organization does not adopt the
          amendments made by the mass submitter, it wil no longer be identical
          to or a minor modifier of the mass submitter plan.

      (d) No amendment to the Plan shall be effective if it authorizes or
          permits any part of the Trust Fund (other than such part as is
          required to pay taxes and administration expenses) to be used for or
          diverted to any purpose other than for the exclusive benefit of the
          Participants or their Beneficiaries or estates; or causes any
          reduction in the amount credited to the account of any Participant; or
          causes or permits any portion of the Trust Fund to revert to or become
          property of the Employer.

      (e) Except as permitted by Regulations (including Regulation 1.411(d)-4),
          no Plan amendment or transaction having the effect of a Plan amendment
          (such as a merger, plan transfer or similar transaction) shall be
          effective if it eliminates or reduces any "Section 

                                       77
<PAGE>
 
          411(d)(6) protected benefit" or adds or modifies conditions relating
          to "Section 411(d)(6) protected benefits" the result of which is a
          further restriction on such benefit unless such protected benefits are
          preserved with respect to benefits accrued as of the later of the
          adoption date or effective date of the amendment. "Section 411(d)(6)
          protected benefits" are benefits described in Code Section
          411(d)(6)(A), early retirement benefits and retirement-type subsidies,
          and optional forms of benefit.

8.2   TERMINATION

      (a) The Employer shall have the right at any time to terminate the Plan by
          delivering to the Trustee and Administrator written notice of such
          termination. Upon any full or partial termination all amounts credited
          to the affected Participants' Accounts shall become 100% Vested and
          shall not thereafter be subject to forfeiture, and all unallocated
          amounts shall be allocated to the accounts of all Participants in
          accordance with the provisions hereof.

      (b) Upon the full termination of the Plan, the Employer shall direct the
          distribution of the assets to Participants in a manner which is
          consistent with and satisfies the provisions of Section 6.5.
          Distributions to a Participant shall be made in cash (or in property
          if permitted in the Adoption Agreement) or through the purchase of
          irrevocable nontransferable deferred commitments from the Insurer.
          Except as permitted by Regulations, the termination of the Plan shall
          not result in the reduction of "Section 411(d)(6) protected benefits"
          as described in Section 8.1.

8.3   MERGER OR CONSOLIDATION

      This Plan may be merged or consolidated with, or its assets and/or
      liabilities may be transferred to any other plan only if the benefits
      which would be received by a Participant of this Plan, in the event of a
      termination of the plan immediately after such transfer, merger or
      consolidation, are at least equal to the benefits the Participant would
      have received if the Plan had terminated immediately before the transfer,
      merger or consolidation and such merger or consolidation does not
      otherwise result in the elimination or reduction of any "Section 411(d)(6)
      protected benefits" as described in Section 8.1(e).

      In the event that a money purchase plan of the Employer is merged or
      restated as a profit sharing plan, monies accrued under the money purchase
      plan shall continue to be subject to the distribution restrictions
      contained in the money purchase plan prior to its merger or restatement as
      a profit sharing plan.

                                  ARTICLE IX
                                 MISCELLANEOUS

9.1   EMPLOYER ADOPTIONS

      (a) Any organization may become the Employer hereunder by executing the
          Adoption Agreement in form satisfactory to the Trustee, and it shall
          provide such additional information as the Trustee may require. The
          consent of the Trustee to act as such shall be signified by its
          execution of the Adoption Agreement.

      (b) Except as otherwise provided in this Plan, the affiliation of the
          Employer and the participation of its Participants shall be separate
          and apart from that of any other employer and its participants
          hereunder.

9.2   PARTICIPANT'S RIGHTS

      This Plan shall not be deemed to constitute a contract between the
      Employer and any Participant or to be a consideration or an inducement for
      the employment of any Participant or Employee. Nothing contained in this
      Plan shall be deemed to give any Participant or Employee the right to be
      retained in the service of the Employer or to interfere with the right of
      the Employer to discharge any Participant or Employee at any time
      regardless of the effect which such discharge shall have upon him as a
      Participant of this Plan.

9.3   ALIENATION

      (a) Subject to the exceptions provided below, no benefit which shall be
          payable to any person (including a Participant or his Beneficiary)
          shall be subject in any manner to anticipation, alienation, sale,
          transfer, assignment, pledge, encumbrance, or charge, and any attempt
          to anticipate, alienate, sell, transfer, assign, pledge, encumber, or
          charge the same shall be void; and no such benefit shall in any manner
          be liable for, or subject to, the debts, contracts, liabilities,
          engagements, or torts of any such person, nor shall it be subject to
          attachment or legal process for or against such person, and the same
          shall not be recognized except to such extent as may be required by
          law.

      (b) This provision shall not apply to the extent a Participant or
          Beneficiary is indebted to the Plan, for any reason, under any
          provision of this Plan. At the time a distribution is to be made to or
          for a Participant's or Beneficiary's benefit, such proportion of the
          amount to be distributed as shall equal such indebtedness shall be
          paid to the Plan, to apply against or discharge such indebtedness.
          Prior to making a payment, however, the Participant or Beneficiary
          must be given written notice by the Administrator that such
          indebtedness is to be so paid in whole or part from his Participant's
          accounts. If the Participant or Beneficiary does not agree that the
          indebtedness is a valid claim against his Vested Participant's
          accounts, he shall be entitled to a review of the validity of the
          claim in accordance with procedures provided in Sections 2.12 and
          2.13.

                                       79
<PAGE>
 
      (c) This provision shall not apply to a "qualified domestic relations
          order" defined in Code Section 414(p), and those other domestic
          relations orders permitted to be so treated by the Administrator under
          the provisions of the Retirement Equity Act of 1984. The Administrator
          shall establish a written procedure to determine the qualified status
          of domestic relations orders and to administer distributions under
          such qualified orders. Further, to the extent provided under a
          "qualified domestic relations order", a former spouse of a Participant
          shall be treated as the spouse or surviving spouse for all purposes
          under the Plan.

9.4   CONSTRUCTION OF PLAN

      This Plan and Trust shall be construed and enforced according to the Act
      and the laws of the State or Commonwealth in which the Employer's
      principal office is located, other than its laws respecting choice of law,
      to the extent not pre-empted by the Act.

9.5   GENDER AND NUMBER

      Wherever any words are used herein in the masculine, feminine or neuter
      gender, they shall be construed as though they were also used in another
      gender in all cases where they would so apply, and whenever any words are
      used herein in the singular or plural form, they shall be construed as
      though they were also used in the other form in all cases where they would
      so apply.

9.6   LEGAL ACTION

      In the event any claim, suit, or proceeding is brought regarding the Trust
      and/or Plan established hereunder to which the Trustee or the
      Administrator may be a party, and such claim, suit, or proceeding is
      resolved in favor of the Trustee or Administrator, they shall be entitled
      to be reimbursed from the Trust Fund for any and all costs, attorney's
      fees, and other expenses pertaining thereto incurred by them for which
      they shall have become liable.

9.7   PROHIBITION AGAINST DIVERSION OF FUNDS

      (a) Except as provided below and otherwise specifically permitted by law,
          it shall be impossible by operation of the Plan or of the Trust, by
          termination of either, by power of revocation or amendment, by the
          happening of any contingency, by collateral arrangement or by any
          other means, for any part of the corpus or income of any Trust Fund
          maintained pursuant to the Plan or any funds contributed thereto to be
          used for, or diverted to, purposes other than the exclusive benefit of
          Participants, Retired Participants, or their Beneficiaries.

      (b) In the event the Employer shall make a contribution under a mistake of
          fact pursuant to Section 403(c)(2)(A) of the Act, the Employer may
          demand repayment of such contribution at any time within one (1) year
          following the time of payment and the Trustees shall return such
          amount to the Employer within the one (1) year period. Earnings of the
          Plan attributable to the contributions may not be returned to the
          Employer but any losses attributable thereto must reduce the amount so
          returned.

                                       80
<PAGE>
 
      (c) If this Plan is a nontrusteed, then no Contract will be purchased
          under the Plan unless such Contract or a separate definite written
          agreement between the Employer and the Insurer provides that: (1) no
          value under Contracts providing benefits under the Plan or credits
          determined by the Insurer (on account of dividends, earnings, or other
          experience rating credits, surrender or cancellation credits) with
          respect to such Contracts may be paid or returned to the Employer or
          diverted to or used for other than the exclusive benefit of the
          Participants or their Beneficiaries. However, any contribution made by
          the Employer because of a mistake of fact must be returned to the
          Employer within one year of the contribution.

          If this Plan is funded by individual Contracts that provide a
          Participant's benefit under the Plan, such individual Contracts shall
          constitute the Participant's account balance. If this Plan is funded
          by group contracts, under the group annuity or group insurance
          contract, premiums or other consideration received by the insurance
          company must be allocated to Participants' accounts under the Plan.

9.8   BONDING

      Every Fiduciary, except a bank or an insurance company, unless exempted by
      the Act and regulations thereunder, shall be bonded in an amount not less
      than 10% of the amount of the funds such Fiduciary handles; provided,
      however, that the minimum bond shall be $1,000 and the maximum bond,
      $500,000. The amount of funds handled shall be determined at the beginning
      of each Plan Year by the amount of funds handled by such person, group, or
      class to be covered and their predecessors, if any, during the preceding
      Plan Year, or if there is no preceding Plan Year, then by the amount of
      the funds to be handled during the then current year. The bond shall
      provide protection to the Plan against any loss by reason of acts of fraud
      or dishonesty by the Fiduciary alone or in connivance with others. The
      surety shall be a corporate surety company (as such term is used in Act
      Section 412(a)(2)), and the bond shall be in a form approved by the
      Secretary of Labor. Notwithstanding anything in the Plan to the contrary,
      the cost of such bonds shall be an expense of and may, at the election of
      the Administrator, be paid from the Trust Fund or by the Employer.

9.9   EMPLOYER'S AND TRUSTEE'S PROTECTIVE CLAUSE

      Neither the Employer nor the Trustee, nor their successors, shall be
      responsible for the validity of any Contract issued hereunder or for the
      failure on the part of the Insurer to make payments provided by any such
      Contract, or for the action of any person which may delay payment or
      render a Contract null and void or unenforceable in whole or in part.

9.10  INSURER'S PROTECTIVE CLAUSE

      The Insurer who shall issue Contracts hereunder shall not have any
      responsibility for the validity of this Plan or for the tax or legal
      aspects of this Plan. The Insurer shall be protected and held harmless in
      acting in accordance with any written direction of the Trustee, and shall
      have no duty to see to the application of any funds paid to the Trustee,
      nor be required to question any actions directed by the Trustee.
      Regardless of any provision of this Plan, the Insurer shall not be
      required to take or permit any action or allow any benefit or privilege
      contrary to the terms of any Contract which it issues hereunder, or the
      rules of the Insurer.

9.11  RECEIPT AND RELEASE FOR PAYMENTS

      Any payment to any Participant, his legal representative, Beneficiary, or
      to any guardian or committee appointed for such Participant or Beneficiary
      in accordance with the provisions of this Plan, shall, to the extent
      thereof, be in full satisfaction of all claims hereunder against the
      Trustee and the Employer.

9.12  ACTION BY THE EMPLOYER

      Whenever the Employer under the terms of the Plan is permitted or required
      to do or perform any act or matter or thing, it shall be done and
      performed by a person duly authorized by its legally constituted
      authority.

9.13  NAMED FIDUCIARIES AND ALLOCATION OF RESPONSIBILITY

      The "named Fiduciaries" of this Plan are (1) the Employer, (2) the
      Administrator, (3) the Trustee, and (4) any Investment Manager appointed
      hereunder. The named Fiduciaries shall have only those specific powers,
      duties, responsibilities, and obligations as are specifically given them
      under the Plan. In general, the Employer shall have the sole
      responsibility for making the contributions provided for under Section
      4.1; and shall have the sole authority to appoint and remove the Trustee
      and the Administrator; to formulate the Plan's "funding policy and
      method"; and to amend the elective provisions of the Adoption Agreement or
      terminate, in whole or in part, the Plan. The Administrator shall have the
      sole responsibility for the administration of the Plan, which
      responsibility is specifically described in the Plan. The Trustee shall
      have the sole responsibility of management of the assets held under the
      Trust, except those assets, the management of which has been assigned to
      an Investment Manager, who shall be solely responsible for the management
      of the assets assigned to it, all as specifically provided in the Plan.
      Each named Fiduciary warrants that any directions given, information
      furnished, or action taken by it shall be in accordance with the
      provisions of the Plan, authorizing or providing for such direction,
      information or action. Furthermore, each named Fiduciary may rely upon any
      such direction, information or action of another named Fiduciary as being
      proper under the Plan, and is not required under the Plan to inquire into
      the propriety of any such direction, information or action. It is intended
      under the Plan that each named Fiduciary shall be responsible for the
      proper exercise of its own powers, duties, responsibilities and
      obligations under the Plan. No named Fiduciary shall guarantee the Trust
      Fund in any manner against investment loss or depreciation in asset value.
      Any person or group may serve in more than one Fiduciary capacity.

9.14  HEADINGS

      The headings and subheadings of this Plan have been inserted for
      convenience of reference and are to be ignored in any construction of the
      provisions hereof.

9.15  APPROVAL BY INTERNAL REVENUE SERVICE

      (a) Notwithstanding anything herein to the contrary, if, pursuant to a
          timely application filed by or in behalf of the Plan, the Commissioner
          of Internal Revenue Service or his delegate should determine that the
          Plan does not initially qualify as a tax-exempt plan under Code
          Sections 401 and 501, and such determination is not contested, or if
          contested, is finally upheld, then if the Plan is a new plan, it shall
          be void ab initio and all amounts contributed to the Plan, by the
          Employer, less expenses paid, shall be returned within one year and
          the Plan shall terminate, and the Trustee shall be discharged from all
          further obligations. If the disqualification relates to an amended
          plan, then the Plan shall operate as if it had not been amended and
          restated.

      (b) Except as specifically stated in the Plan, any contribution by the
          Employer to the Trust Fund is conditioned upon the deductibility of
          the contribution by the Employer under the Code and, to the extent any
          such deduction is disallowed, the Employer may within one (1) year
          following a final determination of the disallowance, whether by
          agreement with 

                                       83
<PAGE>
 
          the Internal Revenue Service or by final decision of a court of
          competent jurisdiction, demand repayment of such disallowed
          contribution and the Trustee shall return such contribution within one
          (1) year following the disallowance. Earnings of the Plan attributable
          to the excess contribution may not be returned to the Employer, but
          any losses attributable thereto must reduce the amount so returned.

9.16  UNIFORMITY

      All provisions of this Plan shall be interpreted and applied in a uniform,
      nondiscriminatory manner.

9.17  PAYMENT OF BENEFITS

      Benefits under this Plan shall be paid, subject to Section 6.10 and
      Section 6.11 only upon death, Total and Permanent Disability, normal or
      early retirement, termination of employment, or upon Plan Termination.

                            PARTICIPATING EMPLOYERS

10.1  ELECTION TO BECOME A PARTICIPATING EMPLOYER

      Notwithstanding anything herein to the contrary, with the consent of the
      Employer and Trustee, any Affiliated Employer may adopt this Plan and all
      of the provisions hereof, and participate herein and be known as a
      Participating Employer, by a properly executed document evidencing said
      intent and will of such Participating Employer.

10.2  REQUIREMENTS OF PARTICIPATING EMPLOYERS

      (a) Each Participating Employer shall be required to select the same
          Adoption Agreement provisions as those selected by the Employer other
          than the Plan Year, the Fiscal Year, and such other items that must,
          by necessity, vary among employers.

      (b) Each such Participating Employer shall be required to use the same
          Trustee as provided in this Plan.

      (c) The Trustee may, but shall not be required to, commingle, hold and
          invest as one Trust Fund all contributions made by Participating
          Employers, as well as all increments thereof.

      (d) The transfer of any Participant from or to an Employer participating
          in this Plan, whether he be an Employee of the Employer or a
          Participating Employer, shall not affect such Participant's rights
          under the Plan, and all amounts credited to such Participant's
          accounts as well as his accumulated service time with the transferor
          or predecessor, and his length of participation in the Plan, shall
          continue to his credit.

      (e) Any expenses of the Plan which are to be paid by the Employer or borne
          by the Trust Fund shall be paid by each Participating Employer in the
          same proportion that the total amount standing to the credit of all
          Participants employed by such Employer bears to the total standing to
          the credit of all Participants.

10.3  DESIGNATION OF AGENT

      Each Participating Employer shall be deemed to be a part of this Plan;
      provided, however, that with respect to all of its relations with the
      Trustee and Administrator for the purpose of this Plan, each Participating
      Employer shall be deemed to have designated irrevocably the Employer as
      its agent. Unless the context of the Plan clearly indicates the contrary,
      the word "Employer" shall be deemed to include each Participating Employer
      as related to its adoption of the Plan.

                                       85
<PAGE>
 
10.4  EMPLOYEE TRANSFERS

      It is anticipated that an Employee may be transferred between
      Participating Employers, and in the event of any such transfer, the
      Employee involved shall carry with him his accumulated service and
      eligibility. No such transfer shall effect a termination of employment
      hereunder, and the Participating Employer to which the Employee is
      transferred shall thereupon become obligated hereunder with respect to
      such Employee in the same manner as was the Participating Employer from
      whom the Employee was transferred.

10.5  PARTICIPATING EMPLOYER'S CONTRIBUTION AND FORFEITURES

      Any contribution or Forfeiture subject to allocation during each Plan Year
      shall be allocated among all Participants of all Participating Employers
      in accordance with the provisions of this Plan. On the basis of the
      information furnished by the Administrator, the Trustee shall keep
      separate books and records concerning the affairs of each Participating
      Employer hereunder and as to the accounts and credits of the Employees of
      each Participating Employer. The Trustee may, but need not, register
      Contracts so as to evidence that a particular Participating Employer is
      the interested Employer hereunder, but in the event of an Employee
      transfer from one Participating Employer to another, the employing
      Employer shall immediately notify the Trustee thereof.

10.6  AMENDMENT

      Amendment of this Plan by the Employer at any time when there shall be a
      Participating Employer hereunder shall only be by the written action of
      each and every Participating Employer and with the consent of the Trustee
      where such consent is necessary in accordance with the terms of this Plan.

10.7  DISCONTINUANCE OF PARTICIPATION

      Except in the case of a Standardized Plan, any Participating Employer
      shall be permitted to discontinue or revoke its participation in the Plan
      at any time. At the time of any such discontinuance or revocation,
      satisfactory evidence thereof and of any applicable conditions imposed
      shall be delivered to the Trustee. The Trustee shall thereafter transfer,
      deliver and assign Contracts and other Trust Fund assets allocable to the
      Participants of such Participating Employer to such new Trustee as shall
      have been designated by such Participating Employer, in the event that it
      has established a separate pension plan for its Employees provided,
      however, that no such transfer shall be made if the result is the
      elimination or reduction of any "Section 411(d)(6) protected benefits" in
      accordance with Section 8.1(e). If no successor is designated, the Trustee
      shall retain such assets for the Employees of said Participating Employer
      pursuant to the provisions of Article VII hereof. In no such event shall
      any part of the corpus or income of the Trust Fund as it relates to such
      Participating Employer be used for or diverted for purposes other than for
      the exclusive benefit of the Employees of such Participating Employer.

10.8  ADMINISTRATOR'S AUTHORITY

      The Administrator shall have authority to make any and all necessary rules
      or regulations, binding upon all Participating Employers and all
      Participants, to effectuate the purpose of this Article.

10.9  PARTICIPATING EMPLOYER CONTRIBUTION FOR AFFILIATE

      If any Participating Employer is prevented in whole or in part from making
      a contribution which it would otherwise have made under the Plan by reason
      of having no current or accumulated earnings or profits, or because such
      earnings or profits are less than the contribution which it would
      otherwise have made, then, pursuant to Code Section 404(a)(3)(B), so much
      of the contribution which such Participating Employer was so prevented
      from making may be made, for the benefit of the participating employees of
      such Participating Employer, by other Participating Employers who are
      members of the same affiliated group within the meaning of Code Section
      1504 to the extent of their current or accumulated earnings or profits,
      except that such contribution by each such other Participating Employer
      shall be limited to the proportion of its total current and accumulated
      earnings or profits remaining after adjustment for its contribution to the
      Plan made without regard to this paragraph which the total prevented
      contribution bears to the total current and accumulated earnings or
      profits of all the Participating Employers remaining after adjustment for
      all contributions made to the Plan without regard to this paragraph.

      A Participating Employer on behalf of whose employees a contribution is
      made under this paragraph shall not be required to reimburse the
      contributing Participating Employers.

                                  ARTICLE XI
                          CASH OR DEFERRED PROVISIONS

      Notwithstanding any provisions in the Plan to the contrary, the provisions
      of this Article shall apply with respect to any 401(k) Profit Sharing
      Plan.

11.1  FORMULA FOR DETERMINING EMPLOYER'S CONTRIBUTION

      For each Plan Year, the Employer shall contribute to the Plan:

      (a) The amount of the total salary reduction elections of all Participants
          made pursuant to Section 11.2(a), which amount shall be deemed an
          Employer's Elective Contribution, plus

      (b) If specified in E3 of the Adoption Agreement, a matching contribution
          equal to a percentage or amount in the Adoption Agreement of the
          Participant's Compensation, plus

      (c) If specified in E4 of the Adoption Agreement, a discretionary amount,
          if any, which shall be deemed an Employer's Non-Elective Contribution,
          plus

      (d) If specified in E5 of the Adoption Agreement, a Qualified Non-Elective
          Contribution.

      (e) Notwithstanding the foregoing, however, the Employer's contributions
          for any Fiscal Year shall not exceed the maximum amount allowable as a
          deduction to the Employer under the provisions of Code Section 404.
          All contributions by the Employer shall be made in cash or in such
          property as is acceptable to the Trustee.

      (f) Except, however, to the extent necessary to provide the top heavy
          minimum allocations, the Employer shall make a contribution even if it
          exceeds current or accumulated Net Profit or the amount which is
          deductible under Code Section 404.

      (g) Employer Elective Contributions accumulated through payroll deductions
          shall be paid to the Trustee as of the earliest date on which such
          contributions can reasonably be segregated from the Employer's general
          assets, but in any event within ninety (90) days from the date on
          which such amounts would otherwise have been payable to the
          Participant in cash. The provisions of Department of Labor regulations
          2510.3-102 are incorporated herein by reference. Furthermore, any
          additional Employer contributions which are allocable to the
          Participant's Elective Account for a Plan Year shall be paid to the
          Plan no later than the twelve-month period immediately following the
          close of such Plan Year.

11.2  PARTICIPANT'S SALARY REDUCTION ELECTION

      (a) If selected in the Adoption Agreement, each Participant may elect to
          defer his Compensation which would have been received in the Plan
          Year, but for the deferral election, subject to the limitations of
          this Section and the Adoption Agreement. A deferral election (or
          modification of an earlier election) may not be made with respect to
          Compensation which is currently available on or before the date the
          Participant executed such election, or if later, the latest of the
          date the Employer adopts this cash or deferred arrangement, or the
          date such arrangement first became effective. Any elections made
          pursuant to this Section shall become effective as soon as is
          administratively feasible.

          Additionally, if elected in the Adoption Agreement, each Participant
          may elect to defer and have allocated for a Plan Year all or a portion
          of any cash bonus attributable to services performed by the
          Participant for the Employer during such Plan Year and which would
          have been received by the Participant on or before two and one-half
          months following the end of the Plan Year but for the deferral. A
          deferral election may not be made with respect to cash bonuses which
          are currently available on or before the date the Participant executed
          such election. Notwithstanding the foregoing, cash bonuses
          attributable to services performed by the Participant during a Plan
          Year but which are to be paid to the Participant later than two and
          one-half months after the close of such Plan Year will be subjected to
          whatever deferral election is in effect at the time such cash bonus
          would have otherwise been received.

          The amount by which Compensation and/or cash bonuses are reduced shall
          be that Participant's Deferred Compensation and be treated as an
          Employer Elective Contribution and allocated to that Participant's
          Elective Account.

          Once made, a Participant's election to reduce Compensation shall
          remain in effect until modified or terminated. Modifications may be
          made as specified in the Adoption Agreement, and terminations may be
          made at any time. Any modification or termination of an election will
          become effective as soon as is administratively feasible.

      (b) The balance in each Participant's Elective Account shall be fully
          Vested at all times and shall not be subject to Forfeiture for any
          reason.

      (c) Amounts held in the Participant's Elective Account and Qualified Non-
          Elective Account may be distributable as permitted under the Plan, but
          in no event prior to the earlier of:

          (1)   a Participant's separation from service, Total and Permanent
                Disability, or death;

          (2)   a Participant's attainment of age 59 1/2;

          (3)   the proven financial hardship of a Participant, subject to the
                limitations of Section 11.8;

                                       89
<PAGE>
 
          (4)   the termination of the Plan without establishment or maintenance
                of another defined contribution plan, other than an employee
                stock ownership plan (as defined in Code Section 4975(e) or 409)
                or a simplified employee pension plan (as defined in Code
                Section 408(k));

          (5)   the date of the sale by the Employer to an entity that is not an
                Affiliated Employer of substantially all of the assets (within
                the meaning of Code Section 409(d)(2)) with respect to a
                Participant who continues employment with the corporation
                acquiring such assets; or

          (6)   the date of the sale or other disposition by a corporation of
                its interest in a subsidiary (within the meaning of Code Section
                409(d)(3)) if such corporation continues to maintain the Plan,
                but only with respect to a Participant who continues employment
                with such subsidiary.

                All distributions that may be made pursuant to one or more of
                the foregoing events are subject to the spousal and Participant
                consent requirements (if applicable) contained in Code Sections
                401(a)(11) and 417. In addition, distributions after March 31,
                1988, that are triggered by any of the events enumerated in
                subparagraphs (4), (5) and (6) above shall be made in a lump
                sum.

          (d)   In any Plan Year beginning after December 31, 1987, a
                Participant's Deferred Compensation made under this Plan and all
                other plans, contracts or arrangements of the Employer
                maintaining this Plan shall not exceed the limitation imposed by
                Code Section 402(g), as in effect for the calendar year in which
                such Plan Year began. If such dollar limitation is exceeded
                solely from elective deferrals made under this Plan or any other
                Plan maintained by the Employer, a Participant will be deemed to
                have notified the Administrator of such excess amount which
                shall be distributed in a manner consistent with Section
                11.2(f). This dollar limitation shall be adjusted annually
                pursuant to the method provided in Code Section 415(d) in
                accordance with Regulations.

          (e)   In the event a Participant has received a hardship distribution
                pursuant to Regulation 1.401(k)-1(d)(2)(iii)(B) from any other
                plan maintained by the Employer or from his Participant's
                Elective Account pursuant to Section 11.8, then such Participant
                shall not be permitted to elect to have Deferred Compensation
                contributed to the Plan on his behalf for a period of twelve
                (12) months following the receipt of the distribution.
                Furthermore, the dollar limitation under Code Section 402(g)
                shall be reduced, with respect to the Participant's taxable year
                following the taxable year in which the hardship distribution
                was made, by the amount of such Participant's Deferred
                Compensation, if any, made pursuant to this Plan (and any other
                plan maintained by the Employer) for the taxable year of the
                hardship distribution.

          (f)   If a Participant's Deferred Compensation under this Plan
                together with any elective deferrals (as defined in Regulation
                1.402(g)-1(b)) under another 

                                       90
<PAGE>
 
                qualified cash or deferred arrangement (as defined in Code
                Section 401(k)), a simplified employee pension (as defined in
                Code Section 408(k)), a salary reduction arrangement (within the
                meaning of Code Section 3121(a)(5)(D)), a deferred compensation
                plan under Code Section 457, or a trust described in Code
                Section 501(c)(18) cumulatively exceed the limitation imposed by
                Code Section 402(g) (as adjusted annually in accordance with the
                method provided in Code Section 415(d) pursuant to Regulations)
                for such Participant's taxable year, the Participant may, not
                later than March 1st following the close of his taxable year,
                notify the Administrator in writing of such excess and request
                that his Deferred Compensation under this Plan be reduced by an
                amount specified by the Participant. In such event, the
                Administrator shall direct the Trustee to distribute such excess
                amount (and any Income allocable to such excess amount) to the
                Participant not later than the first April 15th following the
                close of the Participant's taxable year. Distributions in
                accordance with this paragraph may be made for any taxable year
                of the Participant which begins after December 31, 1986. Any
                distribution of less than the entire amount of Excess Deferred
                Compensation and Income shall be treated as a pro rata
                distribution of Excess Deferred Compensation and Income. The
                amount distributed shall not exceed the Participant's Deferred
                Compensation under the Plan for the taxable year. Any
                distribution on or before the last day of the Participant's
                taxable year must satisfy each of the following conditions:

                (1)  the Participant shall designate the distribution as Excess
                     Deferred Compensation;

                (2)  the distribution must be made after the date on which the
                     Plan received the Excess Deferred Compensation; and

                (3)  the Plan must designate the distribution as a distribution
                     of Excess Deferred Compensation.

                Any distribution under this Section shall be made first from
                unmatched Deferred Compensation and, thereafter, simultaneously
                from Deferred Compensation which is matched and matching
                contributions which relate to such Deferred Compensation.
                However, any such matching contributions which are not Vested
                shall be forfeited in lieu of being distributed.

                For the purpose of this Section, "Income" means the amount of
                income or loss allocable to a Participant's Excess Deferred
                Compensation and shall be equal to the sum of the allocable gain
                or loss for the taxable year of the Participant and the
                allocable gain or loss for the period between the end of the
                taxable year of the Participant and the date of distribution
                ("gap period"). The income or loss allocable to each such period
                is calculated separately and is determined by multiplying the
                income or loss allocable to the Participant's Deferred
                Compensation for the respective period by a fraction. The
                numerator of the fraction is the Participant's Excess Deferred
                Compensation for the taxable year of the Participant. The
                denominator is the balance, as of the last day of the 

                                       91
<PAGE>
 
                respective period, of the Participant's Elective Account that is
                attributable to the Participant's Deferred Compensation reduced
                by the gain allocable to such total amount for the respective
                period and increased by the loss allocable to such total amount
                for the respective period.

                In lieu of the "fractional method" described above, a "safe
                harbor method" may be used to calculate the allocable income or
                loss for the "gap period." Under such "safe harbor method,"
                allocable income or loss for the "gap period" shall be deemed to
                equal ten percent (10%) of the income or loss allocable to a
                Participant's Excess Deferred Compensation for the taxable year
                of the Participant multiplied by the number of calendar months
                in the "gap period." For purposes of determining the number of
                calendar months in the "gap period," a distribution occurring on
                or before the fifteenth day of the month shall be treated as
                having been made on the last day of the preceding month and a
                distribution occurring after such fifteenth day shall be treated
                as having been made on the first day of the next subsequent
                month.

                Income or loss allocable to any distribution of Excess Deferred
                Compensation on or before the last day of the taxable year of
                the Participant shall be calculated from the first day of the
                taxable year of the Participant to the date on which the
                distribution is made pursuant to either the "fractional method"
                or the "safe harbor method".

                Notwithstanding the above, for any distribution under this
                Section which is made after August 15, 1991, such distribution
                shall not include any income for the "gap period". Further
                provided, for any distribution under this Section which is made
                after August 15, 1991, the amount of Income may be computed
                using a reasonable method that is consistent with Section
                4.3(c), provided such method is used consistently for all
                Participants and for all such distributions for the Plan Year.

                Notwithstanding the above, for the 1987 calendar year, Income
                during the "gap period" shall not be taken into account.

          (g)   Notwithstanding the above, a Participant's Excess Deferred
                Compensation shall be reduced, but not below zero, by any
                distribution and/or recharacterization of Excess Contributions
                pursuant to Section 11.5(a) for the Plan Year beginning with or
                within the taxable year of the Participant.

          (h)   At Normal Retirement Date, or such other date when the
                Participant shall be entitled to receive benefits, the fair
                market value of the Participant's Elective Account shall be used
                to provide benefits to the Participant or his Beneficiary.

          (i)   Employer Elective Contributions made pursuant to this Section
                may be segregated into a separate account for each Participant
                in a federally insured savings account, certificate of deposit
                in a bank or savings and loan association, money market
                certificate, or other short-term debt security 

                                       92

                acceptable to the Trustee until such time as the allocations
                pursuant to Section 11.3 have been made.

          (j)   The Employer and the Administrator shall adopt a procedure
                necessary to implement the salary reduction elections provided
                for herein.

11.3  ALLOCATION OF CONTRIBUTION, FORFEITURES AND EARNINGS

      (a) The Administrator shall establish and maintain an account in the name
          of each Participant to which the Administrator shall credit as of each
          Anniversary Date, or other valuation date, all amounts allocated to
          each such Participant as set forth herein.

      (b) The Employer shall provide the Administrator with all information
          required by the Administrator to make a proper allocation of the
          Employer's contributions for each Plan Year. Within a reasonable
          period of time after the date of receipt by the Administrator of such
          information, the Administrator shall allocate such contribution as
          follows:

          (1)   With respect to the Employer's Elective Contribution made
                pursuant to Section 11.1(a), to each Participant's Elective
                Account in an amount equal to each such Participant's Deferred
                Compensation for the year.

          (2)   With respect to the Employer's Matching Contribution made
                pursuant to Section 11.1(b), to each Participant's Account, or
                Participant's Elective Account as selected in E3 of the Adoption
                Agreement, in accordance with Section 11.1(b).

                Except, however, a Participant who is not credited with a Year
                of Service during any Plan Year shall or shall not share in the
                Employer's Matching Contribution for that year as provided in E3
                of the Adoption Agreement. However, for Plan Years beginning
                after 1989, if this is a standardized Plan, a Participant shall
                share in the Employer's Matching Contribution regardless of
                Hours of Service.

          (3)   With respect to the Employer's Non-Elective Contribution made
                pursuant to Section 11.1(c), to each Participant's Account in
                accordance with the provisions of Sections 4.3(b)(2) or
                4.3(b)(3), whichever is applicable, 4.3(k) and 4.3(l).

          (4)   With respect to the Employer's Qualified Non-Elective
                Contribution made pursuant to Section 11.1(d), to each
                Participant's Qualified Non-Elective Contribution Account in the
                same proportion that each such Participant's Compensation for
                the year bears to the total Compensation of all Participants for
                such year. However, for any Plan Year beginning prior to January
                1, 1990, and if elected in the non-standardized Adoption
                Agreement for any Plan Year beginning on or after January 1,
                1990, a Participant who is not credited with a Year of Service
                during any Plan Year shall not share in the Employer's Qualified
                Non-Elective Contribution for that year, unless required
                pursuant to 

                                       93
<PAGE>
 
                Section 4.3(h). In addition, the provisions of Sections 4.3(k)
                and 4.3(l) shall apply with respect to the allocation of the
                Employer's Qualified Non-Elective contribution.

      (c) Notwithstanding anything in the Plan to the contrary, for Plan Years
          beginning after December 31, 1988, in determining whether a Non-Key
          Employee has received the required minimum allocation pursuant to
          Section 4.3(f) such Non-Key Employee's Deferred Compensation and
          matching contributions used to satisfy the "Actual Deferral
          Percentage" test pursuant to Section 11.4(a) or the "Actual
          Contribution Percentage" test of Section 11.6(a) shall not be taken
          into account.

      (d) Notwithstanding anything herein to the contrary, participants who
          terminated employment during the Plan Year shall share in the salary
          reduction contributions made by the Employer for the year of
          termination without regard to the Hours of Service credited.

      (e) Notwithstanding anything herein to the contrary (other than Sections
          11.3(d) and 11.3(g)), any Participant who terminated employment during
          the Plan Year for reasons other than death, Total and Permanent
          Disability, or retirement shall or shall not share in the allocations
          of the Employer's Matching Contribution made pursuant to Section
          11.1(b), the Employer's Non-Elective Contributions made pursuant to
          Section 11.1(c), the Employer's Qualified Non-Elective Contribution
          made pursuant to Section 11.1(d), and Forfeitures as provided in the
          Adoption Agreement. Notwithstanding the foregoing, for Plan Years
          beginning after 1989, if this is a standardized Plan, any such
          terminated Participant shall share in such allocations provided the
          terminated Participant completed more than 500 Hours of Service.

      (f) Notwithstanding anything herein to the contrary, Participants
          terminating for reasons of death, Total and Permanent Disability, or
          retirement shall share in the allocation of the Employer's Matching
          Contribution made pursuant to Section 11.1(b), the Employer's Non-
          Elective Contributions made pursuant to Section 11.1(c), the
          Employer's Qualified Non-Elective Contribution made pursuant to
          Section 11.1(d), and Forfeitures as provided in this Section
          regardless of whether they completed a Year of Service during the Plan
          Year.

      (g) Notwithstanding any election in the Adoption Agreement to the
          contrary, if this is a non-standardized Plan that would otherwise fail
          to meet the requirements of Code Sections 401(a)(26), 410(b)(1), or
          410(b)(2)(A)(i) and the Regulations thereunder because Employer
          matching Contributions made pursuant to Section 11.1(b), Employer Non-
          Elective Contributions made pursuant to Section 11.1(c) or Employer
          Qualified Non-Elective Contributions made pursuant to Section 11.1(d)
          have not been allocated to a sufficient number or percentage of
          Participants for a Plan Year, then the following rules shall apply:

          (1)   The group of Participants eligible to share in the respective
                contributions for the Plan Year shall be expanded to include the
                minimum number of Participants who would not otherwise be
                eligible as are necessary to satisfy the 

                                       94
<PAGE>
 
                applicable test specified above. The specific participants who
                shall become eligible under the terms of this paragraph shall be
                those who are actively employed on the last day of the Plan Year
                and, when compared to similarly situated Participants, have
                completed the greatest number of Hours of Service in the Plan
                Year.

          (2)   If after application of paragraph (1) above, the applicable test
                is still not satisfied, then the group of Participants eligible
                to share for the Plan Year shall be further expanded to include
                the minimum number of Participants who are not actively employed
                on the last day of the Plan Year as are necessary to satisfy the
                applicable test. The specific Participants who shall become
                eligible to share shall be those Participants, when compared to
                similarly situated Participants, who have completed the greatest
                number of Hours of Service in the Plan Year before terminating
                employment.

11.4  ACTUAL DEFERRAL PERCENTAGE TESTS

      (a) Maximum Annual Allocation: For each Plan Year beginning after December
          31, 1986, the annual allocation derived from Employer Elective
          Contributions and Qualified Non-Elective Contributions to a
          Participant's Elective Account and Qualified Non-Elective Account
          shall satisfy one of the following tests:

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

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

                However, for Plan Years beginning after December 31, 1988, to
                prevent the multiple use of the alternative method described in
                (2) above and Code Section 401(m)(9)(A), any Highly Compensated
                Participant eligible to make elective deferrals pursuant to
                Section 11.2 and to make Employee contributions or to receive
                matching contributions under this Plan or under any other plan
                maintained by the Employer or an Affiliated Employer shall have
                his actual deferral ratio reduced pursuant to Regulation
                1.401(m)-2, the provisions of which are incorporated herein by
                reference.

      (b) For the purposes of this Section "Actual Deferral Percentage" means,
          with respect to the Highly Compensated Participant group and Non-
          Highly Compensated Participant group for a Plan Year, the average of
          the ratios, calculated separately for each Participant in 

                                       95
<PAGE>
 
          such group, of the amount of Employer Elective Contributions and
          Qualified Non-Elective Contributions allocated to each Participant's
          Elective Account and Qualified Non-Elective Account for such Plan
          Year, to such Participant's 414(s) Compensation for such Plan Year.
          The actual deferral ratio for each Participant and the "Actual
          Deferral Percentage" for each group, for Plan Years beginning after
          December 31, 1988, shall be calculated to the nearest one-hundredth of
          one percent of the Participant's 414(s) Compensation. Employer
          Elective Contributions allocated to each Non-Highly Compensated
          Participant's Elective Account shall be reduced by Excess Deferred
          Compensation to the extent such excess amounts are made under this
          Plan or any other plan maintained by the Employer.

      (c) For the purpose of determining the actual deferral ratio of a Highly
          Compensated Participant 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 the year, the following shall apply:

          (1)   The combined actual deferral ratio for the family group (which
                shall be treated as one Highly Compensated Participant) shall be
                the greater of: (i) the ratio determined by aggregating Employer
                Elective Contributions and 414(s) Compensation of all eligible
                Family Members who are Highly Compensated Participants without
                regard to family aggregation; and (ii) the ratio determined by
                aggregating Employer Elective Contributions and 414(s)
                Compensation of all eligible Family Members (including Highly
                Compensated Participants). However, in applying the adjusted
                $150,000 limit to 414(s) Compensation for Plan Years beginning
                after December 31, 1988, Family Members shall include only the
                affected Employee's spouse and any lineal descendants who have
                not attained age 19 before the close of the Plan Year.

          (2)   The Employer Elective Contributions and 414(s) Compensation of
                all Family Members shall be disregarded for purposes of
                determining the "Actual Deferral Percentage" of the Non-Highly
                Compensated Participant 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.

          (d)   For the purposes of this Section 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 401(a)(4) or 410(b) (other than Code Section
                401(b)(2)(A)(ii) as in effect for Plan Years beginning after
                December 31, 1988), 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 satisfy Code Sections 

                                       96
<PAGE>
 
                401(a)(4), 410(b) and 401(k). In such a case, the cash or
                deferred arrangements included in such plans and the plans
                including such arrangements shall be treated as one arrangement
                and as one plan for purposes of this Section 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 paragraph
                (e) only if they have the same plan year.

                Notwithstanding the above, for Plan Years beginning after
                December 31, 1988, 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 Section and Code Sections
                401(a)(4), 410(b) and 401(k).

          (e)   For the purposes of this Section, if a Highly Compensated
                Participant is a Participant under two (2) or more cash or
                deferred arrangements (other than a cash or deferred arrangement
                which is part of an employee stock ownership plan as defined in
                Code Section 4975(e)(7) for Plan Years beginning after December
                31, 1988) of the Employer or an Affiliated 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
                Participant. However, for Plan Years beginning after December
                31, 1988, 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.

11.5  ADJUSTMENT TO ACTUAL DEFERRAL PERCENTAGE TESTS

      In the event that the initial allocations of the Employer's Elective
      Contributions and Qualified Non-Elective Contributions do not satisfy one
      of the tests set forth in Section 11.4, for Plan Years beginning after
      December 31, 1986, the Administrator shall adjust Excess Contributions
      pursuant to the options set forth below:

      (a) On or before the fifteenth day of the third month following the end of
          each Plan Year, the Highly Compensated Participant having the highest
          actual deferral ratio shall have his portion of Excess Contributions
          distributed to him and/or at his election recharacterized as a
          voluntary Employee contribution pursuant to Section 4.7 until one of
          the tests set forth in Section 11.4 is satisfied, or until his actual
          deferral ratio equals the actual deferral ratio of the Highly
          Compensated Participant having the second highest actual deferral
          ratio. This process shall continue until one of the tests set forth in
          Section 11.4 is satisfied. For each Highly Compensated Participant,
          the amount of Excess Contributions is equal to the Elective
          Contributions and Qualified Non-Elective Contributions made on behalf
          of such Highly Compensated Participant (determined prior to the
          application of this paragraph) minus the amount determined by
          multiplying the Highly Compensated Participant's actual deferral ratio
          (determined after application of this paragraph) by his 414(s)
          Compensation. However, in determining the amount of Excess
          Contributions to be distributed and/or recharacterized with respect to
          an affected 

                                       97
<PAGE>
 
          Highly Compensated Participant as determined herein, such amount shall
          be reduced by any Excess Deferred Compensation previously distributed
          to such affected Highly Compensated Participant for his taxable year
          ending with or within such Plan Year. Any distribution and/or
          recharacterization of Excess Contributions shall be made in accordance
          with the following:

          (1)   With respect to the distribution of Excess Contributions
                pursuant to (a) above, such distribution:

                (i)  may be postponed but not later than the close of the Plan
                     Year following the Plan Year to which they are allocable;

                (ii) shall be made first from unmatched Deferred Compensation
                     and, thereafter, simultaneously from Deferred Compensation
                     which is matched and matching contributions (even if
                     qualified) which relate to such Deferred Compensation.
                     However, any such matching contributions shall be forfeited
                     in lieu of being distributed;

                (iii)shall be made from Qualified Non-Elective Contributions
                     only to the extent that Excess Contributions exceed the
                     balance in the Participant's Elective Account attributable
                     to Deferred Compensation and Employer matching
                     contributions.

                (iv) shall be adjusted for Income; and

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

          (2)   With respect to the recharacterization of Excess Contributions
                pursuant to (a) above, such recharacterized amounts:

                (i)  shall be deemed to have occurred on the date on which the
                     last of those Highly Compensated Participants with Excess
                     Contributions to be recharacterized is notified of the
                     recharacterization and the tax consequences of such
                     recharacterization;

                (ii) for Plan Years ending on or before August 8, 1988, may be
                     postponed but not later than October 24, 1988;

                (iii)shall not exceed the amount of Deferred Compensation on
                     behalf of any Highly Compensated Participant for any Plan
                     Year;

                (iv) shall be treated as voluntary Employee contributions for
                     purposes of Code Section 401(a)(4) and Regulation 1.401(k)-
                     1(b). However, for purposes of Sections 2.2 and 4.3(f),
                     recharacterized Excess Contributions continue to be treated
                     as Employer contributions that are Deferred Compensation.
                     For Plan Years beginning after December 31, 1988, 

                                       98
<PAGE>
 
                     Excess Contributions recharacterized as voluntary Employee
                     contributions shall continue to be nonforfeitable and
                     subject to the same distribution rules provided for in
                     Section 11.2(c);

                (v)  which relate to Plan Years ending on or before October 24,
                     1988, may be treated as either Employer contributions or
                     voluntary Employee contributions and therefore shall not be
                     subject to the restrictions of Section 11.2(c);

                (vi) are not permitted if the amount recharacterized plus
                     voluntary Employee contributions actually made by such
                     Highly Compensated Participant, exceed the maximum amount
                     of voluntary Employee contributions (determined prior to
                     application of Section 11.6) that such Highly Compensated
                     Participant is permitted to make under the Plan in the
                     absence of recharacterization;

               (vii) shall be adjusted for Income.

          (3)   Any distribution and/or recharacterization of less than the
                entire amount of Excess Contributions shall be treated as a pro
                rata distribution and/or recharacterization of Excess
                Contributions and Income.

          (4)   Excess Contributions of Participants who are subject to the
                family member aggregation rules shall be allocated among the
                family members in proportion to the Elective Contributions (and
                amounts treated as Elective Contributions) of each family member
                that is combined to determine the combined actual deferral
                percentage.

      (b) Within twelve (12) months after the end of the Plan Year, the Employer
          shall make a special Qualified Non-Elective Contribution on behalf of
          any or all Non-Highly Compensated Participants in an amount sufficient
          to satisfy one of the tests set forth in Section 11.4(a).

      (c) For purposes of this Section, "Income" means the income or loss
          allocable to Excess Contributions which shall equal the sum of the
          allocable gain or loss for the Plan Year and the allocable gain or
          loss for the period between the end of the Plan Year and the date of
          distribution ("gap period"). The income or loss allocable to Excess
          Contributions for the Plan Year and the "gap period" is calculated
          separately and is determined by multiplying the income or loss for the
          Plan Year or the "gap period" by a fraction. The numerator of the
          fraction is the Excess Contributions for the Plan Year. The
          denominator of the fraction is the total of the Participant's Elective
          Account attributable to Elective Contributions and the Participant's
          Qualified Non-Elective Account as of the end of the Plan Year or the
          "gap period," reduced by the gain allocable to such total amount for
          the Plan Year or the "gap period" and increased by the loss allocable
          to such total amount for the Plan Year or the "gap period."

                                       99
<PAGE>
 
          In lieu of the "fractional method" described above, a "safe harbor
          method" may be used to calculate the allocable Income for the "gap
          period". Under such "safe harbor method", allocable Income for the
          "gap period" shall be deemed to equal ten percent (10%) of the Income
          allocable to Excess Contributions for the Plan Year of the Participant
          multiplied by the number of calendar months in the "gap period". For
          purposes of determining the number of calendar months in the "gap
          period", a distribution occurring on or before the fifteenth day of
          the month shall be treated as having been made on the last day of the
          preceding month and a distribution occurring after such fifteenth day
          shall be treated as having been made on the first day of the next
          subsequent month.

          Notwithstanding the above, for Plan Years which began in 1987, Income
          during the "gap period" shall not be taken into account.

      (d) Any amounts not distributed or recharacterized within 2 1/2 months
          after the end of the Plan Year shall be subject to the 10% Employer
          excise tax imposed by Code Section 4979.

11.6  ACTUAL CONTRIBUTION PERCENTAGE TESTS

      (a) The "Actual Contribution Percentage," for Plan Years beginning after
          the later of the Effective Date of this Plan or December 31, 1986, for
          the Highly Compensated Participant group shall not exceed the greater
          of:

          (1)   125 percent of such percentage for the Non-Highly Compensated
                Participant group; or

          (2)   the lesser of 200 percent of such percentage for the Non-Highly
                Compensated Participant group, or such percentage for the Non-
                Highly Compensated Participant group plus 2 percentage points.
                However, for Plan Years beginning after December 31, 1988, to
                prevent the multiple use of the alternative method described in
                this paragraph and Code Section 401(m)(9)(A), any Highly
                Compensated Participant eligible to make elective deferrals
                pursuant to Section 11.2 or any other cash or deferred
                arrangement maintained by the Employer or an Affiliated Employer
                and to make Employee contributions or to receive matching
                contributions under any plan maintained by the Employer or an
                Affiliated Employer shall have his actual deferral 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.

      (b) For the purposes of this Section and Section 11.7, "Actual
          Contribution Percentage" for a Plan Year means, with respect to the
          Highly Compensated Participant group and Non-Highly Compensated
          Participant group, the average of the ratios (calculated separately
          for each Participant in each group) of:

          (1)   the sum of Employer matching contributions made pursuant to
                Section 11.1(b) (to the extent such matching contributions are
                not used to satisfy the tests set 

                                      100
<PAGE>
 
                forth in Section 11.4), and voluntary Employee contributions
                made pursuant to Section 4.7 and Excess Contributions
                recharacterized as voluntary Employee contributions pursuant to
                Section 11.5 on behalf of each such Participant for such Plan
                Year; to

          (2)   the Participant's "414(s) Compensation" for such Plan Year.

      (c) For purposes of determining the "Actual Contribution Percentage" and
          the amount of Excess Aggregate Contributions pursuant to Section
          11.7(d), only Employer matching contributions (excluding matching
          contributions forfeited pursuant to Section 11.2(f), 11.5(a) or
          11.7(a)) contributed to the Plan prior to the end of the succeeding
          Plan Year shall be considered. In addition, the Administrator may
          elect to take into account, with respect to Employees eligible to have
          Employer matching contributions made pursuant to Section 11.1(b) or
          voluntary Employee contributions made pursuant to Section 4.7
          allocated to their accounts, elective deferrals (as defined in
          Regulation 1.402(g)-1(b)) and qualified non-elective contributions (as
          defined in Code Section 401(m)(4)(C)) contributed to any plan
          maintained by the Employer. Such elective deferrals and qualified non-
          elective contributions shall be treated as Employer matching
          contributions subject to Regulation 1.401(m)-1(b)(2) which is
          incorporated herein by reference. However, for Plan Years beginning
          after December 31, 1988, the Plan Year must be the same as the plan
          year of the plan to which the elective deferrals and the qualified 
          non-elective contributions are made.

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

          (1)   The combined actual contribution ratio for the family group
                (which shall be treated as one Highly Compensated Participant)
                shall be the greater of: (i) the ratio determined by aggregating
                Employer matching contributions made pursuant to Section 11.1(b)
                (to the extent such matching contributions are not used to
                satisfy the tests set forth in Section 11.4), voluntary Employee
                contributions made pursuant to Section 4.7, Excess Contributions
                recharacterized as voluntary Employee contributions pursuant to
                Section 11.5 and 414(s) Compensation of all eligible Family
                Members who are Highly Compensated Participants without regard
                to family aggregation; and (ii) the ratio determined by
                aggregating Employer matching contributions made pursuant to
                Section 11.1(b) (to the extent such matching contributions are
                not used to satisfy the tests set forth in Section 11.4),
                voluntary Employee contributions made pursuant to Section 4.7,
                Excess Contributions recharacterized as voluntary Employee
                contributions pursuant to Section 11.5 and 414(s) Compensation
                of all eligible Family Members (including Highly Compensated
                Participants). However, in applying the adjusted $150,000 limit
                to 414(s) Compensation for Plan Years beginning after December
                31, 1988, Family Members shall include only the affected
                Employee's spouse and any 

                                      101
<PAGE>
 
                lineal descendants who have not attained age 19 before the close
                of the Plan Year.

          (2)   The Employer matching contributions made pursuant to Section
                11.1(b) (to the extent such matching contributions are not used
                to satisfy the tests set forth in Section 11.4), voluntary
                Employee contributions made pursuant to Section 4.7, Excess
                Contributions recharacterized as voluntary Employee
                contributions pursuant to Section 11.5 and 414(s) Compensation
                of all Family Members shall be disregarded for purposes of
                determining the "Actual Contribution Percentage" of the Non-
                Highly Compensated Participant 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.

      (e) For purposes of this Section and Code Sections 401(a)(4), 410(b) and
          401(m), if two or more plans of the Employer to which matching
          contributions, Employee contributions, or both, are made are treated
          as one plan for purposes of Code Sections 401(a)(4) or 410(b) (other
          than the average benefits test under Code Section 410(b)(2)(A)(ii) as
          in effect for Plan Years beginning after December 31, 1988), such
          plans shall be treated as one plan. In addition, two or more plans of
          the Employer to which matching contributions, Employee contributions,
          or both, are made may be considered as a single plan for purposes of
          determining whether or not such plans satisfy Code Sections 401(a)(4),
          410(b) and 401(m). In such a case, the aggregated plans must satisfy
          this Section and Code Sections 401(a)(4), 410(b) and 401(m) as though
          such aggregated plans were a single plan. For plan years beginning
          after December 31, 1989, plans may be aggregated under this paragraph
          only if they have the same plan year.

          Notwithstanding the above, for Plan Years beginning after December 31,
          1988, an employee stock ownership plan described in Code Section
          4975(e)(7) may not be aggregated with this Plan for purposes of
          determining whether the employee stock ownership plan or this Plan
          satisfies this Section and Code Sections 401(a)(4), 410(b) and 401(m).

      (f) If a Highly Compensated Participant is a Participant under two or more
          plans (other than an employee stock ownership plan as defined in Code
          Section 4975(e)(7) for Plan Years beginning after December 31, 1988)
          which are maintained by the Employer or an Affiliated Employer to
          which matching contributions, Employee contributions, or both, are
          made, all such contributions on behalf of such Highly Compensated
          Participant shall be aggregated for purposes of determining such
          Highly Compensated Participant's actual contribution ratio. However,
          for Plan Years beginning after December 31, 1988, if the plans have
          different plan years, this paragraph shall be applied by treating all
          plans ending with or within the same calendar year as a single plan.

                                      102
<PAGE>
 
      (g) For purposes of Section 11.6(a) and 11.7, a Highly Compensated
          Participant and a Non-Highly Compensated Participant shall include any
          Employee eligible to have matching contributions made pursuant to
          Section 11.1(b) (whether or not a deferred election was made or
          suspended pursuant to Section 11.2(e)) allocated to his account for
          the Plan Year or to make salary deferrals pursuant to Section 11.2 (if
          the Employer uses salary deferrals to satisfy the provisions of this
          Section) or voluntary Employee contributions pursuant to Section 4.7
          (whether or not voluntary Employee contributions are made) allocated
          to his account for the Plan Year.

      (h) For purposes of this Section, "Matching Contribution" shall mean an
          Employer contribution made to the Plan, or to a contract described in
          Code Section 403(b), on behalf of a Participant on account of an
          Employee contribution made by such Participant, or on account of a
          participant's deferred compensation, under a plan maintained by the
          Employer.

11.7  ADJUSTMENT TO ACTUAL CONTRIBUTION PERCENTAGE TESTS

      (a) In the event that for Plan Years beginning after December 31, 1986,
          the "Actual Contribution Percentage" for the Highly Compensated
          Participant group exceeds the "Actual Contribution Percentage" for the
          Non-Highly Compensated Participant group pursuant to Section 11.6(a),
          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 Participant having the highest
          actual contribution ratio, his portion of Excess Aggregate
          Contributions (and Income allocable to such contributions) or, if
          forfeitable, forfeit such non-Vested Excess Aggregate Contributions
          attributable to Employer matching contributions (and Income allocable
          to such Forfeitures) until either one of the tests set forth in
          Section 11.6(a) is satisfied, or until his actual contribution ratio
          equals the actual contribution ratio of the Highly Compensated
          Participant having the second highest actual contribution ratio. This
          process shall continue until one of the tests set forth in Section
          11.6(a) is satisfied. The distribution and/or Forfeiture of Excess
          Aggregate Contributions shall be made in the following order:

          (1)   Employer matching contributions forfeited pursuant to Section
                11.5(a)(1);

          (2)   Any unmatched voluntary Employee contributions shall be
                distributed;

          (3)   Unmatched Deferred Compensation taken into account under the
                actual contribution percentage test shall be distributed;

          (4)   Matched voluntary Employee contributions shall be distributed
                and, simultaneously, matching contributions that relate to such
                voluntary contributions shall be forfeited;

          (5)   Matched Deferred Compensation taken into account under the
                actual contribution percentage test shall be distributed and,
                simultaneously, matching contributions that relate to such
                Deferred Compensation shall be forfeited;

                                      103
<PAGE>
 
          (6)   Any remaining Employer matching contributions shall be
                distributed;

          (7)   Qualified Non-Elective Contributions taken into account under
                the actual contribution percentage test shall be distributed.

      (b) Any distribution or Forfeiture of less than the entire amount of
          Excess Aggregate Contributions (and Income) shall be treated as a pro
          rata distribution 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 Section 4.3. However, no such Forfeiture
          may be allocated to a Highly Compensated Participant whose
          contributions are reduced pursuant to this Section.

      (c) Excess Aggregate Contributions attributable to amounts other than
          voluntary Employee contributions, including forfeited matching
          contributions, shall be treated as Employer contributions for purposes
          of Code Sections 404 and 415 even if distributed from the Plan.

      (d) For the purposes of this Section and Section 11.6, "Excess Aggregate
          Contributions" means, with respect to any Plan Year, the excess of:

          (1)   the aggregate amount of Employer matching contributions made
                pursuant to Section 11.1(b) (to the extent such contributions
                are taken into account pursuant to Section 11.6(a)), voluntary
                Employee contributions made pursuant to Section 4.7, Excess
                Contributions recharacterized as voluntary Employee
                contributions pursuant to Section 11.5 and any Qualified Non-
                Elective Contributions or elective deferrals taken into account
                pursuant to Section 11.6(c) actually made on behalf of the
                Highly Compensated Participant group for such Plan Year, over

          (2)   the maximum amount of such contributions permitted under the
                limitations of Section 11.6(a).

      (e) For each Highly Compensated Participant, the amount of Excess
          Aggregate Contributions is equal to the total Employer matching
          contributions made pursuant to Section 11.1(b) (to the extent taken
          into account pursuant to Section 11.6(a)), voluntary Employee
          contributions made pursuant to Section 4.7, Excess Contributions
          recharacterized as voluntary Employee contributions pursuant to
          Section 11.5 and any Qualified Non-Elective Contributions or elective
          deferrals taken into account pursuant to Section 11.6(c) on behalf of
          the Highly Compensated Participant (determined prior to the
          application of this paragraph) minus the amount determined by
          multiplying the Highly Compensated Participant's actual contribution
          ratio (determined after application of this paragraph) by his 414(s)
          Compensation. The actual contribution ratio must be rounded to the
          nearest one-hundredth of one percent for Plan Years beginning after
          December 31, 1988. In no case shall the amount of Excess Aggregate
          Contribution with respect to any Highly Compensated Participant exceed
          the amount of Employer 

                                      104
<PAGE>
 
          matching contributions made pursuant to Section 11.1(b) (to the extent
          taken into account pursuant to Section 11.6(a)), voluntary Employee
          contributions made pursuant to Section 4.7, Excess Contributions
          recharacterized as voluntary Employee contributions pursuant to
          Section 11.5 and any Qualified Non-Elective Contributions or elective
          deferrals taken into account pursuant to Section 11.6(c) on behalf of
          such Highly Compensated Participant for such Plan Year.

      (f) The determination of the amount of Excess Aggregate Contributions with
          respect to any Plan Year shall be made after the first determining the
          Excess Contributions, if any, to be treated as voluntary Employee
          contributions due to recharacterization for the plan year of any other
          qualified cash or deferred arrangement (as defined in Code Section
          401(k)) maintained by the Employer that ends with or within the Plan
          Year or which are treated as voluntary Employees contributions due to
          recharacterization pursuant to Section 11.5.

      (g) Excess Aggregate Contributions of Participants who are subject to the
          family member aggregation rules shall be allocated among the family
          members in proportion to the voluntary Employee contributions, if
          applicable, and matching contributions (or amounts treated as matching
          contributions) of each family member that is combined to determine the
          combined actual contribution percentage.

      (h) Notwithstanding the above, within twelve (12) months after the end of
          the Plan Year, the Employer may make a special Qualified Non-Elective
          Contribution on behalf of any or all Non-Highly Compensated
          Participants in an amount sufficient to satisfy one of the tests set
          forth in Section 11.6. A separate accounting shall be maintained for
          the purpose of excluding such contributions from the "Actual Deferral
          Percentage" tests pursuant to Section 11.4.

      (i) For purposes of this Section, "Income" means the income or loss
          allocable to Excess Aggregate Contributions which shall equal the sum
          of the allocable gain or loss for the Plan Year and the allocable gain
          or loss for the period between the end of the Plan Year and the date
          of distribution ("gap period"). The income or loss allocable to Excess
          Aggregate Contributions for the Plan Year and the "gap period" is
          calculated separately and is determined by multiplying the income or
          loss for the Plan Year or the "gap period" by a fraction. The
          numerator of the fraction is the Excess Aggregate Contributions for
          the Plan Year. The denominator of the fraction is the total
          Participant's Account and Voluntary Contribution Account attributable
          to Employer matching contributions subject to Section 11.6, voluntary
          Employee contributions made pursuant to Section 4.7, and any Qualified
          Non-Elective Contributions and elective deferrals taken into account
          pursuant to Section 11.6(c) as of the end of the Plan Year or the "gap
          period", reduced by the gain allocable to such total amount for the
          Plan Year or the "gap period" and increased by the loss allocable to
          such total amount for the Plan Year or the "gap period".

          In lieu of the "fractional method" described above, a "safe harbor
          method" may be used to calculate the allocable Income for the "gap
          period". Under such "safe harbor method", allocable Income for the
          "gap period" shall be deemed to equal ten percent (10%) of the 

                                      105
<PAGE>
 
          Income allocable to Excess Aggregate Contributions for the Plan Year
          of the Participant multiplied by the number of calendar months in the
          "gap period". For purposes of determining the number of calendar
          months in the "gap period", a distribution occurring on or before the
          fifteenth day of the month shall be treated as having been made on the
          last day of the preceding month and a distribution occurring after
          such fifteenth day shall be treated as having been made on the first
          day of the next subsequent month.

          The Income allocable to Excess Aggregate Contributions resulting from
          recharacterization of Elective Contributions shall be determined and
          distributed as if such recharacterized Elective Contributions had been
          distributed as Excess Contributions.

          Notwithstanding the above, for Plan Years which began in 1987, Income
          during the "gap period" shall not be taken into account.

11.8  ADVANCE DISTRIBUTION FOR HARDSHIP

      (a) The Administrator, at the election of the Participant, shall direct
          the Trustee to distribute to any Participant in any one Plan Year up
          to the lesser of (1) 100% of his Vested accounts, as specified in the
          Adoption Agreement, valued as of the last Anniversary Date or other
          valuation date or (2) the amount necessary to satisfy the immediate
          and heavy financial need of the Participant. Any distribution made
          pursuant to this Section shall be deemed to be made as of the first
          day of the Plan Year or, if later, the valuation date immediately
          preceding the date of distribution, and the account from which the
          distribution is made shall be reduced accordingly. Withdrawal under
          this Section shall be authorized only if the distribution is on
          account of one of the following or any other items permitted by the
          Internal Revenue Service:

          (1)   Expenses for medical care described in Code Section 213(d)
                previously incurred by the Participant, his spouse, or any of
                his dependents (as defined in Code Section 152) or necessary for
                those persons to obtain medical care as described in Code
                Section 213(d);

          (2)   Costs directly related to the purchase (excluding mortgage
                payments) of a principal residence for the Participant;

          (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

          (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.

      (b) Distributions may be made from the Participant's Vested accounts.

                                      106
<PAGE>
 
      (c) No distribution shall be made pursuant to this Section unless the
          Administrator, based upon the Participant's representation and such
          other facts as are known to the Administrator, determines that all of
          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. The amount of the
                immediate and heavy financial need may include any amounts
                necessary to pay any federal, state or local income taxes or
                penalties reasonably anticipated to result from the
                distribution.

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

          (3)   The Plan, and all other plans maintained by the Employer,
                provide that the Participant's elective deferrals and voluntary
                Employee contributions will be suspended for at least twelve
                (12) months after receipt of the hardship distribution; and

          (4)   The Plan, and all other plans maintained by the Employer,
                provide that the Participant may not make elective deferrals for
                the Participant's taxable year immediately following the taxable
                year of the hardship distribution in excess of the applicable
                limit under Code Section 402(g) for such next taxable year less
                the amount of such Participant's elective deferrals for the
                taxable year of the hardship distribution.

      (d) Notwithstanding the above, distributions from the Participant's
          Elective Account and Qualified Non-Elective Account pursuant to this
          Section shall be limited solely to the Participant's Deferred
          Compensation and any income attributable thereto credited to the
          Participant's Elective Account as of December 31, 1988.

      (e) Any distribution made pursuant to this Section shall be made in a
          manner which is consistent with and satisfies the provisions of
          Section 6.5, including, but not limited to, all notice and consent
          requirements of Code Sections 411(a)(11) and 417 and the Regulations
          thereunder.

E9   LIMITATIONS ON ALLOCATIONS (Plan Section 4.4)

     a.   If any Participant is or was covered under another qualified defined
          contribution plan maintained by the Employer, other than a Master or
          Prototype Plan, or if the Employer maintains a welfare benefit fund,
          as defined in Code Section 419(e), or an individual medical account,
          as defined in Code Section 415(l)(2), or a simplified employee
          pension, as defined in Code Section 408(k), under which amounts are
          treated as Annual Additions with respect to any Participant in this
          Plan:

          1.   (X)  N/A.
          2.   ( )  The provisions of Plan Section 4.4(b) will apply as if the
                    other plan were a Master or Prototype Plan.
          3.   ( )  Provide the method under which the Plans will limit total
                    Annual Additions to the Maximum Permissible Amount, and will
                    properly reduce any Excess Amounts, in a manner that
                    precludes Employer discretion.
             
                    ------------------------------------------------------------

                    ------------------------------------------------------------

                    ------------------------------------------------------------
       
          b.   If any Participant is or ever has been a Participant in a defined
               benefit plan maintained by the Employer:

               1.  (X)  N/A.
               2.  ( )  In any Limitation Year, the Annual Additions credited to
                        the Participant under this Plan may not cause the sum of
                        the Defined Benefit Plan Fraction and the Defined
                        Contribution Fraction to exceed 1.0. If the Employer's
                        contribution that would otherwise be made on the
                        Participant's behalf during the limitation year would
                        cause the 1.0 limitation to be exceeded, the rate of
                        contribution under this Plan will be reduced so that the
                        sum of the fractions equals 1.0. If the 1.0 limitation
                        is exceeded because of an Excess Amount, such Excess
                        Amount will be reduced in accordance with Plan Section
                        4.4(a)(4).
               3.  ( )  Provide the method under which the plans involved will
                        satisfy the 1.0 limitation in a manner that precludes
                        Employer discretion.

(the sponsor) has acknowledged the use of the Plan. Such acknowledgment is for

          LONG-TERM SAVINGS PLAN FOR SALARIED AND AFFILIATED EMPLOYEES

               As Amended and Restated Effective January 1, 1989


          The Illinois Consolidated Telephone Company Long-Term Savings Plan for
Salaried Employees (the "Plan") was adopted by Illinois Consolidated Telephone
Company (the "Company"), effective October 1, 1984 to permit certain employees
to defer the Federal income tax on certain portions of their salaries as
provided by the Internal Revenue Code, to increase certain of its employees'
interest in the Company by providing a medium through which they may share in
the profitable operations of the Company and to furnish additional security to
certain of its employees who become permanently disabled.  The Plan was
subsequently amended to provide for the adoption of the Plan by Related
Companies (as defined below).  The Plan was further amended, and restated,
effective January 1, 1985, to make changes required to comply with the Code and
ERISA, both as amended by the Retirement Equity Act of 1984, and to change the
name of the Plan to reflect its adoption by certain Related Companies.  The Plan
is hereby further amended and restated, as set forth below, to comply with the
requirements of the Tax Reform Act of 1986, the Omnibus Budget Reconciliation
Acts of 1986 and 1987, the Technical and Miscellaneous Revenue Act of 1988, the
Revenue Reconciliation Acts of 1989 and 1990, the Unemployment Compensation
Amendments of 1992, the Omnibus Budget Reconciliation Act of 1993 and certain
governmental rules and regulations, and to make certain other changes.  Except
where otherwise indicated herein, this 

                                      -1-
<PAGE>
 
restatement of the Plan is effective as of January 1, 1989 with respect to each
Employee who earns an Hour of Service on or after January 1, 1989. Except as may
be required by ERISA or the Code, the rights of any person whose status as an
Employee has terminated shall be determined pursuant to the Plan as in effect on
the date such employment status terminated, unless a subsequently adopted
provision of the Plan is made specifically applicable to such person.

          3.3  Suspension of Long-Term Savings Agreements.  (a) A Participant
               ------------------------------------------                       
may voluntarily suspend a Long-Term Savings Agreement for an indefinite period
of time.  If a notice of suspension, on such forms as shall be required by the
Company, is received on or before (i) the tenth day of the month that contains
the applicable Wage Payment Date, in the case of a salaried Participant, or (ii)
the tenth day of the month preceding the month that contains the applicable Wage
Payment Date, in the case of an hourly paid Participant, such suspension shall
be effective as of the applicable Wage Payment Date.  If such notice is received
after the tenth day of the applicable month, such suspension shall be effective
as of the first Wage Payment Date that occurs in the following month.  A
Participant will not be permitted to make up amounts subject to a Long-Term
Savings Agreement for any period of suspension.  A Participant who makes an
election to suspend a Long-Term Savings Agreement pursuant to this Section may
reinstate such Agreement effective as of his first Wage Payment Date following
any subsequent Entry Date designated by him if such Participant again executes
and files with the Company a Long-Term Savings Agreement, and any other forms
required by the Company, no later than the tenth day of the month preceding the
month that contains the applicable Wage Payment Date.

          (b) The Company, at its election, may amend, suspend or revoke a Long-
Term Savings Agreement with a Participant at any time if the Company determines
that such amendment or revocation is necessary to ensure that the Annual
Additions to the Accounts of a Participant do not exceed the Maximum 

                                      -23-
<PAGE>
 
Permissible Amount for such Participant for that Year or to ensure that the
requirements of Section 3.1(c), 3.4 or 6.2 are met for such Year.

          3.4  Limitations on Salary Deferral Contributions.  
               --------------------------------------------        
          (a) Notwithstanding anything to the contrary contained elsewhere in
the Plan or contained in any Long-Term Savings Agreement, all Long-Term Savings
Agreements entered into with respect to any Plan Year shall be valid only if one
of the tests set forth in paragraph (b) next below is satisfied for such Plan
Year. In determining whether such tests are satisfied, all Salary Deferral
Contributions and excess Salary Deferral Contributions under Section 3.1(c) of
Highly Compensated Participants, if any, made with respect to such Plan Year
shall be considered.

          (b) For each Plan Year the Actual Deferral Percentage for Highly
Compensated Eligible Employees shall bear to the Actual Deferral Percentage for
all other Eligible Employees a relationship that satisfies either of the
following tests:

          (i)  The Actual Deferral Percentage for Highly Compensated Eligible
               Employees is not more than the Actual Deferral Percentage of all
               other Eligible Employees multiplied by 1.25; or

          (ii) The Actual Deferral Percentage for Highly Compensated Eligible
               Employees is not more than the Actual Deferral Percentage for all
               other Eligible Employees multiplied by two 

                                      -24-
<PAGE>
 
               and the excess of the Actual Deferral Percentage for the group of
               Highly Compensated Eligible Employees over that of all other
               Eligible Employees is not more than two percentage points.

The Actual Deferral Percentage of any Eligible Employee or group of Eligible
Employees shall be calculated to the nearest 1/100 of one percent (.0001).  The
Actual Deferral Percentage of an Eligible Employee who is not credited with any
Salary Deferral Contributions for a Plan Year is zero.

          (c) If at the end of any Plan Year neither of the tests set forth in
paragraph (b) next above is satisfied for such Year, then:

          (i)  Long-Term Savings Agreements entered into for such Year by Highly
               Compensated Participants shall be valid only to the extent
               permitted by one of the tests set forth in paragraph (b) next
               above and Salary Deferral Contributions made by the Company for
               such Year for Highly Compensated Participants shall be reduced in
               the manner set forth in paragraph (ii) next below to the extent
               necessary to comply with one of the tests set forth in paragraph
               (b) next above.  All Salary Deferral Contributions so reduced,
               adjusted for earnings, gains and losses allocable thereto,
               pursuant to Section 401(k)(8) of the Code, shall be allocated and
               distributed in the manner provided in Section 3.5.

                                      -25-
<PAGE>
 
          (ii)  Reductions pursuant to paragraph (i) next above shall be 
                effected with respect to Highly Compensated Participants 
                pursuant to the following procedure: (A) the Actual Deferral 
                Percentage of the Highly Compensated Participant with the 
                highest Actual Deferral Percentage shall be reduced to the 
                extent necessary to cause such Highly Compensated Participant's
                Actual Deferral Percentage to equal the Actual Deferral 
                Percentage of the Highly Compensated Participant with the next 
                highest Actual Deferral Percentage. The process shall be 
                repeated until the Plan satisfies one of the tests set forth 
                in (i) or (ii) of paragraph (b) for such Plan Year.

          (iii) Long-Term Savings Agreements entered into by all Participants
                who are not Highly Compensated shall be valid and Salary
                Deferral Contributions made by the Company for such Participants
                shall not be changed.

The calculations, reductions and allocations required by this Section 3.4(c) and
Section 3.5 shall be made by the Company with respect to a Plan Year at any time
prior to the close of the following Plan Year.

          (d) It at any time during a Plan Year the Company, in its sole
discretion, determines that neither of the tests set forth in paragraph (b) of
this 

                                      -26-
<PAGE>
 
Section 3.4 may be met for such Plan Year, the Company shall have the unilateral
right during the Plan Year to do either of the following:

          (i)  require the prospective reduction, for the balance of such Year
               or any part thereof, of the percentage by which all Highly
               Compensated Participants have elected to reduce their Earnings
               pursuant to Long-Term Savings Agreements.  Such reductions shall
               be made to the extent necessary, in the discretion of the
               Company, to assure that one of the tests set forth in paragraph
               (b) of this Section 3.4 shall be met for the Plan Year, shall be
               based upon estimates made from data available to the Company at
               any time during the Plan Year and shall be made in accordance
               with such nondiscriminatory procedures as the Company shall 
               select. Reductions pursuant to the preceding sentence shall be
               effected with respect to Highly Compensated Participants pursuant
               to the following procedure: the Actual Deferral Percentage of the
               Highly Compensated Participant with the highest Actual Deferral
               Percentage shall be reduced to the extent necessary to cause such
               Highly Compensated Participant's Actual Deferral Percentage to
               equal the Actual Deferral Percentage of the Highly Compensated
               Participant with the next highest Actual Deferral Percentage.
               This process shall be repeated to the extent necessary to assure
               that one of 

                                      -27-
<PAGE>
 
               the tests set forth in (i) or (ii) of paragraph (b) of this
               Section shall not be exceeded for such Plan Year. Long-Term
               Savings Agreements made by all Participants who are not Highly
               Compensated Participants shall be valid and Salary Deferral
               Contributions for such Participants shall not be changed.

          (ii) make an optional contribution for any Plan Year with respect to
               Participants who are not Highly Compensated Participants to the
               extent necessary to assure that one of the tests set forth in
               paragraph (b) of this Section 3.4 shall be met for the Plan Year,
               starting with the lowest paid such Participant and continuing
               with such Participants in the inverse order of their Compensation
               until the optional contribution has been entirely allocated.
               Contributions made pursuant to the preceding sentence shall be
               deemed to be Salary Deferral Contributions for all purposes of
               the Plan, other than for purposes of Section 8.4 of the Plan and
               for purposes of determining the amount of Matching Contributions
               made on such Participant's behalf, and shall be included in the
               value of the Participant's Savings Account attributable to Salary
               Deferral Contributions as of the last day of the Plan Year for
               which they were made. The Company shall pay to the Trustee such
               contributions with 

                                      -28-

Highly Compensated Participant is reduced pursuant to Section 3.4(c), the amount
so reduced shall be allocated and distributed as follows:

          (a) Prior to January 1, 1993, and to the extent permitted by
Regulations issued by the Secretary of the Treasury and as elected by the Highly
Compensated Participant, if the Highly Compensated Participant has not made
Voluntary Contributions equal to the maximum amount permitted under Sections 5.1
and 6.1 of the Plan for the entire time that he has been a Participant in the
Plan, the amount reduced pursuant to Section 3.4(c), adjusted for earnings,
gains and losses allocable thereto for the Plan Year shall be deemed to be
Voluntary Contributions made by the Participant and shall (within the limit
contained in Section 5.1) be allocated to the Participant's Voluntary
Contribution Account; and


          (b) To the extent that the procedure set forth in paragraph (a) above
is not permitted, is no longer applicable, or is not elected by a Highly
Compensated Participant, or if the Highly Compensated Participant makes or is
deemed to have made Voluntary Contributions equal to the maximum amount
permitted by Section 5.1 or Section 6.1 (through contributions made pursuant to
Articles V and VI of the Plan, through the operation of paragraph (a) next
above, or both) any portion of the

amount so reduced pursuant to Section 3.4(c) that is not allocated to the
Participant's Voluntary Contribution Account pursuant to paragraph (a) next
above, adjusted for earnings, gains and losses allocable thereto for the Plan
Year, pursuant to Section 401(k)(8) of the Code, shall be returned to the
Company and as soon as practicable thereafter paid by the Company directly to
the applicable Highly Compensated Participant.

          (c) In all cases, Salary Deferral Contributions made by a Highly
Compensated Participant on and after January 1, 1993 that are reduced pursuant
to Section 3.4(c) shall be returned to such Highly Compensated Participant
pursuant to paragraph (b) above.

          (d) Notwithstanding anything to the contrary contained elsewhere in
the Plan, if a Participant's Salary Deferral Contributions are recharacterized
or returned pursuant to paragraph (a), (b) or (c) above, any Matching
Contributions attributable thereto shall, subject to Article VI, be forfeited
and used to offset the amount of Matching Contributions to be made for the next
Wage Payment Period by the Company and shall be allocated among the Matching
Contributions Account of Participants pursuant to the provisions of Section 7.3.

provided by the Company, to contribute to the Plan a percentage of his Earnings
on an after-tax basis, between one percent (1%) and six percent (6%) (in
increments of one percent (1%)), as elected by the Eligible Employee.  Voluntary
Contributions shall be effected through payroll deductions, commencing as of the
first Wage Payment Date designated by him if such Eligible Employee executes and
delivers to the Company any forms required by the Company, in accordance with
procedures established by the Company, no later than the tenth day of the month
that contains the applicable Wage Payment Date.  Voluntary Contributions shall
be subject to the special rules set forth in this Article V.  Notwithstanding
any provision of the Plan to the contrary, the sum of Voluntary Contributions
made on behalf of an Eligible Employee under this Section, and amounts deemed to
be Voluntary Contributions under Sections 3.1(c) and 3.5(a), shall not exceed
six percent (6%) of the Eligible Employee's Earnings for any Plan Year.

Plan, effective as of the first Wage Payment Date designated by him if such
Participant executes and delivers any form required by the Company to designate
such change no later than the tenth day of the month that contains the
applicable Wage Payment Date. If the Participant executes and delivers such form
later than the tenth day of a month, such change shall be effective as of the
first Wage Payment Date that occurs in the following month.

          (b) For each Plan Year commencing prior to January 1, 1993, a
Participant may voluntarily suspend his Voluntary Contributions for an
indefinite period of time.  If a notice of suspension, on such forms as shall be
required by the Company, is received on or before the tenth day of a month, such
suspension shall be effective as of the next Wage Payment Date that occurs in
that month.  If such notice is received after the tenth day of a month, such
suspension shall be effective as of the first Wage Payment Date that occurs in
the following month.  For each Plan Year commencing prior to January 1, 1993, a
Participant who makes an election to suspend Voluntary Contributions pursuant to
this Section may reinstate such Voluntary Contributions effective as of his
first Wage Payment Date designated by him if such Participant files with the
Company an executed reinstatement form, in accordance with procedures
established by the Company, no later than the tenth day of the month that
contains the applicable Wage Payment Date.

Contributions relate.

402(c)(4) of the Code relating to distributions from qualified plans may elect
to deposit all or any portion (as designated by such Employee in writing to the
Committee) of the amount of such distribution as a Rollover Contribution to this
Plan.  A Rollover Contribution may be made only within sixty (60) days following
the date such Employee receives the distribution from the plan of the Company or
his former employer (or within such additional period as may be provided under
Section 408 of the Code if the Employee shall have made a timely deposit of the
distribution in an individual retirement account).  Subject to paragraph (b)
next below, the Trustee may also receive a Rollover Contribution directly from
the trustee under the plan of the Company or former employer of all or any
portion (as designated by such Employee in writing to the Committee) of the
amount that would otherwise be distributable to an Employee in a covered
classification from such plan.  The Committee shall establish rules and
procedures to implement this Section 5.3, including, without 

                                      -36-

limitation, such procedures as may be appropriate to permit the Committee to
verify the tax qualified status of the plan of the former employer or the
Company and compliance with any applicable provisions of the Code relating to
Rollover Contributions.  The amount contributed or transferred to the Trustee
pursuant to this Section shall be placed in the Employee's Transfer Account for
the benefit of the Employee.  Each Transfer Account shall share in the earnings,
gains and losses of the Trust Fund as set forth in Section 7.8 of the Plan and
shall be distributed at the same times and in the manner set forth in Article
VII below.  Notwithstanding the preceding provisions of this Section, the 
Trustee shall not accept any transfer of an Employee's interest in a qualified
plan of the Company or of a former employer if it is determined that such
acceptance would render this Plan a direct or indirect transferee of a defined
benefit plan, money purchase pension plan (including a target benefit plan),
stock bonus or profit sharing plan that provides for a life annuity form of
payment to the Employee (except to the extent that such transfer is made
pursuant to Section 401(a)(31) of the Code).

          (b) As of any Entry Date, at the written request of a Participant who
is or was a participant under the Illinois Consolidated Telephone Company Long-
Term Savings Plan for Hourly-Paid Employees (the "Hourly Plan"), filed with the
Committee, the Trustee may also receive directly from the trustee under the
Hourly Plan all or any portion (as designated by such Participant in writing to
the Committee) of the vested amount credited to the accounts of such Participant
under the Hourly Plan.  Amounts so transferred shall be placed in the
Participant's 

                                      -37-
<PAGE>
 
Savings Account, Voluntary Contribution Account or Transfer Account, in this
Plan, as the case may be, in the same proportions that such amounts were
credited to the Savings Account, Voluntary Contributions Account, or
attributable to Rollover Contributions, in the Hourly Plan, respectively,
immediately prior to such transfer and shall be held for the benefit of the
Participant.  If the Participant has a loan outstanding under the Hourly Plan at
the time of the transfer, such loan shall be transferred to and assumed by the
Trustee and shall thereafter be treated as a loan made pursuant to Article XI of
this Plan.  Unless otherwise specified by a Participant in writing to the
Committee, a transfer to the Trustee of amounts from the Hourly Plan shall be
governed by this paragraph (b) and not by paragraph (a) next above.

          (c) As of any Entry Date, with respect to each Participant in this
Plan who becomes a participant under the Hourly Plan at any time during the
immediately preceding three months and who makes a written request pursuant to
the terms of the Hourly Plan, the Trustee shall transfer directly to the trustee
of the Hourly Plan, all of the Adjusted Balance of the Savings Account,
Voluntary Contribution Account and Transfer Account of the Participant, as well
as any outstanding loan made to such Participant pursuant to Article XI of the
Plan, to be held and assumed in accordance with the provisions of the Hourly
Plan for the benefit of the Participant.

          6.1  Limitations.  (a) Notwithstanding any provisions of the Plan to
               -----------                                                      
the contrary, the Actual Contribution Percentage of Highly Compensated Eligible
Employees shall bear to the Actual Contribution Percentage for all other
Eligible Employees a relationship that satisfies either of the following tests:

          (i)  The Actual Contribution Percentage for Highly Compensated
               Eligible Employees is not more than the Actual Contribution
               Percentage for all other Eligible Employees multiplied by 1.25;
               or

          (ii) The Actual Contribution Percentage for Highly Compensated
               Eligible Employees is not more than the Actual Contribution
               Percentage for all other Eligible Employees multiplied by two and
               the excess of the Actual Contribution Percentage for the group 
               of Highly Compensated Eligible Employees over that of all other 
               Eligible Employees is not more than two percentage points.

The Actual Contribution Percentage of any Eligible Employee or group of Eligible
Employees shall be calculated to the nearest 1/100 of one percent (.0001).  The

                                      -39-
<PAGE>
 
Actual Contribution Percentage of an Eligible Employee who is not credited with
any Matching Contributions or Voluntary Contributions for a Plan Year is zero.

          (b) If, at the end of any Plan Year, neither of the tests set forth in
paragraph (a) above is satisfied for such Year, then the Matching Contributions
and Voluntary Contributions made for such Year by or on behalf of Highly
Compensated Participants shall be reduced to the extent necessary to comply with
one of the tests set forth in paragraph (a).  Reductions pursuant to the
preceding sentence shall be effected with respect to Highly Compensated
Participants pursuant to the following procedure: the Actual Contribution
Percentage of the Highly Compensated Participant with the highest Actual
Contribution Percentage shall be reduced to the extent necessary to cause such
Highly Compensated Participant's Actual Contribution Percentage to equal the
Actual Contribution Percentage of the Highly Compensated Participant with the
next highest Actual Contribution Percentage.  This process shall be repeated
until one of the tests set forth in paragraph (a) is satisfied for such Plan
Year.  In making such reductions, Voluntary Contributions shall be reduced first
and Matching Contributions shall be reduced last.

          (c) Voluntary Contributions and Matching Contributions made by
Participants who are not Highly Compensated Participants shall be valid and
shall not be changed or affected by this Section.

          (d) If at any time during a Plan Year the Company determines that both
of the tests set forth in paragraph (a) of this Section 6.1 may not be met for
such Plan Year, then:

          (i)  The Company shall have the unilateral right during any Plan Year
               commencing prior to 1993 to require the prospective reduction,
               for the balance of such Plan Year or any part thereof, of the
               percentage of the Earnings of Highly Compensated Participants
               that may be subject to an election pursuant to Section 5.1 to
               make Voluntary Contributions during the Plan Year.  Such
               reductions shall be made to the minimum extent necessary to
               assure that one of the tests in paragraph (a) of this Section 6.1
               shall be met for the Plan Year and shall be based upon estimates
               made from data available to the Company at any time during the
               Plan Year;

          (ii) Reductions pursuant to subsection (i) next above shall be
               effected with respect to Highly Compensated Participants pursuant
               to the following procedure: The Actual Contribution Percentage of
               the Highly Compensated Participant with the highest Actual
               Contribution Percentage shall be reduced by the extent necessary
               to cause such Highly Compensated Participant's Actual
               Contribution Percentage to equal the

                                      -41-
<PAGE>
 
               Actual Contribution Percentage of the Highly Compensated
               Participant with the next highest Actual Contribution Percentage.
               This process shall be repeated to the extent necessary to assure
               that one of the tests set forth in paragraph (a) of this Section
               6.1 shall not be exceeded for such Plan Year.

          (e) Matching Contributions and Voluntary Contributions that are
reduced pursuant to the preceding provisions of this Article for a Plan Year,
adjusted for earnings, gains and losses allocable thereto for such Plan Year
pursuant to Section 401(m) of the Code, shall be returned to the Company and as
soon as practicable thereafter paid by the Company directly to the applicable
Participant.

          (f) The calculations, reductions and payments required by this Article
shall be made by the Company with respect to a Plan Year at any time prior to
the close of the following Plan Year.

          6.2  Multiple Use Test.  If a "Multiple Use of the Alternative
               -----------------                                          
Limitation" occurs in a Plan Year, then, notwithstanding any other provision of
Section 3.4 or of Section 6.1, the test in paragraph (a)(ii) of Section 6.1
shall not be used to satisfy the requirements of this Section for Matching
Contributions and Voluntary Contributions in the same Plan Year that the test
contained in Section 3.4(b)(ii) is used to satisfy the requirements of Section
3.4 with respect to Salary Deferral Contributions.  If the preceding sentence
shall be applicable for a Plan 

                                      -42-
<PAGE>
 
Year, then the Company shall determine whether to use the test in paragraph
(a)(ii) of Section 6.1 to satisfy the requirements of this Section 6.2 or to use
the test in paragraph (b)(ii) of Section 3.4 to satisfy the requirements of
Section 3.4 for such Plan Year.

          A Multiple Use of the Alternative Limitation shall occur in any Plan
Year if all of the following conditions are satisfied in the Plan Year:

          (a) At least one Highly Compensated Eligible Employee is eligible to
authorize Salary Deferral Contributions to be made on his behalf and to make
Voluntary Contributions or to have Matching Contributions allocated to his
Savings Account pursuant to the Plan during such Plan Year;

          (b) The sum of the Actual Deferral Percentage of the entire group of
Highly Compensated Eligible Employees and of the Actual Contribution Percentage
of the entire group of Highly Compensated Eligible Employees for such Plan Year
exceeds the greater of (i) or (ii) below:

          (i)  The sum of:

               (A) 125% of the greater of (I) the Actual Deferral Percentage of
          the group of Eligible Employees who are not Highly Compensated
          Eligible Employees for such Plan Year, or (II) the Actual Contribution
          Percentage of the group of Eligible Employees who are not Highly
          Compensated Eligible Employees for such Plan Year, and

                                      -43-

               (B) Two plus the lesser of (i)(A)(I) or (i)(A)(II) above.  In no
          event, however, shall this amount exceed 200% of the lesser of
          (i)(A)(I) or (i)(A)(II) above;

          (ii)  The sum of:

          (A) 125% of the lesser of (I) the Actual Deferral Percentage of the
          group of Eligible Employees who are not Highly Compensated Eligible
          Employees for such Plan Year, or (II) the Actual Contribution
          Percentage of the group of Eligible Employees who are not Highly
          Compensated Eligible Employees for such Plan Year, and

          (B) Two plus the greater of (ii)(A)(I) or (ii)(A)(II) above.  In no
          event, however, shall this amount exceed 200% of the greater of
          (ii)(A)(I) or (ii)(A)(II) above;

          (c) The Actual Deferral Percentage of the entire group of Highly
Compensated Eligible Employees exceeds the amount described in Section
3.4(b)(i); and

          (d) The Actual Contribution Percentage of the entire group of Highly
Compensated Eligible Employees exceeds the amount described in Section
6.1(a)(i).

                     ALLOCATIONS TO PARTICIPANTS' ACCOUNTS
                     -------------------------------------

          7.1  Separate Accounts.  The Company shall create and maintain a
               -----------------                                            
separate Account for each Participant as shall be needed.  Such Account shall
consist of such of the following as shall be applicable to the Participant: a
Savings Account, a Transfer Account and a Voluntary Contribution Account.
Participants' Accounts are primarily for accounting purposes and do not require
a segregation of the Trust Fund.  The Company may delegate the responsibility
for the maintenance of the Accounts to the Trustee or any agent or agents.

          7.2  Suspense Account.  The Company shall maintain a Suspense
               ----------------                                          
Account, if necessary, pursuant to the provisions of Section 7.6.  The
investment of the balance in the Suspense Account shall be within the sole
discretion of the Company.

          7.3  Allocation of Matching Contributions.  As of each Valuation
               ------------------------------------                         
Date there shall be allocated to the Savings Account of each Participant the
Matching Contribution made by the Company for such Participant pursuant to
Section 4.1 for the Valuation Period ending on such Date.  Subject to Section
3.5(c), an allocation pursuant to this Section shall be made only to the Savings
Account of a Participant whose Earnings were reduced through payroll deductions
pursuant to a Long-Term Savings Agreement during the Valuation Period ending on
such Valuation Date.

                                      -45-

          7.4  Allocations of Salary Deferral Contributions.  (a) As of each
               --------------------------------------------                   
Valuation Date, there shall be allocated to the Savings Account of each
Participant a Salary Deferral Contribution equal to (a) the amount by which the
Participant's Earnings were reduced by payroll deductions during the Valuation
Period ending on such Valuation Date pursuant to such Participant's Long-Term
Savings Agreement, reduced by (b) any applicable amounts pursuant to the
provisions of Sections 3.1(b), 3.1(c) and 3.4(c).

          (b) In the event that the Company elects to make an optional
contribution pursuant to Section 3.4(d)(ii) of the Plan with respect to any Plan
Year, such contribution shall be allocated to the Savings Accounts of the
applicable Participants as of the last day of such Plan Year (even though
receipt of the optional contribution is not received by the Trustee until after
the close of such Plan Year).

          7.5  Allocation of Voluntary and Rollover Contributions.  Voluntary
               --------------------------------------------------              
Contributions made by a Participant shall be allocated to his Voluntary
Contribution Account as of the Valuation Date coinciding with or next following
receipt of such Contributions by the Trustee.  Rollover Contributions made by or
for an Employee shall be allocated to his Transfer Account as of the Valuation
Date coinciding with or next following receipt of such Contributions by the
Trustee.

          7.6  Maximum Allocation.  (a) Except as provided in paragraph (b)
               ------------------

                                      -46-
<PAGE>
 
shall be limited so that the Participant's Annual Additions for such Year do not
exceed the Maximum Permissible Amount.

          (b) If the foregoing limitation on allocations would be exceeded in
any Limitation Year for any Participant as a result of (i) the allocation of
forfeitures; (ii) reasonable error in estimating a Participant's Compensation;
(iii) reasonable error in determining the amount of elective deferrals (within
the meaning of Section 402(g)(3) of the Code) that may be made with respect to a
Participant; or (iv) under such other limited facts and circumstances that the
Commissioner of the Internal Revenue Service, pursuant to Treasury Regulation
1.415-6(b)(6), finds justify the availability of this Section 7.6, the Voluntary
Contributions and Salary Deferral Contributions made by or with respect to such
Participant shall be distributed to him to the extent that any such distribution
would reduce the amount in excess of the limits of this Section 7.6 and any
amount in excess of the limits of this Section 7.6 remaining after such
distribution shall be placed, unallocated to any Participant, in a Suspense
Account.  If a Suspense Account is in existence at any time during a particular
Limitation Year, other than the Limitation Year described in the preceding
sentence, all amounts in the Suspense Account must be allocated to Participants'
Accounts (subject to the limits of this Section 7.6) before any contributions
that would constitute Annual Additions may be made to the Plan for that
Limitation Year.  The excess amount allocated pursuant to this Section 7.6(b)
shall be used to reduce Matching Contributions for the next Limitation Year (and
succeeding Limitation Years, as necessary) for that 

                                      -47-
<PAGE>
 
Participant. However, if that Participant is not covered by the Plan as of the
end of the applicable Limitation Year, then the excess amounts must be held
unallocated in the Suspense Account for the Limitation Year and allocated and
reallocated in the next Limitation Year to all of the remaining Participants in
the Plan. The Suspense Account shall not share in the valuation of Participants'
Accounts and the allocation of earnings set forth in Section 7.8 of the Plan,
and the change in fair market value and allocation of earnings attributable to
the Suspense Account shall be allocated to the remaining Accounts hereunder as
set forth in Section 7.8.

          (c) Any reduction in contributions and allocations made under this
Plan for a Participant's Account required pursuant to this Section 7.6 and
Section 415 of the Code shall be effected, to the extent necessary, in the
following manner: (i) first, Voluntary Contributions made by such Participant
shall be reduced; (ii) next, the Salary Deferral Contribution made by the
Company for the applicable Limitation Year with respect to such Participant
shall be reduced; and (iii) next, the Matching Contribution made by the Company
for the applicable Limitation Year with respect to such Participant shall be
reduced.  The amount of any reductions in Voluntary Contributions and Salary
Deferral Contributions, pursuant to clauses (i) and (ii) of this paragraph (c),
adjusted for gains, earnings and losses allocable thereto, shall be paid by the
Company directly to the affected Participant pursuant to paragraph (b) of this
Section, and any reduction in Matching Contributions pursuant to clause (iii),
adjusted for gains, earnings and losses allocable thereto, shall be treated
pursuant to paragraph (b) of this Section.

                                      -48-
<PAGE>
 
          (d) Upon termination of the Plan, any amounts in a Suspense Account at
the time of such termination shall revert to the Company.

          (e) In the event that any Participant under this Plan is also a
Participant in a defined benefit plan (as defined in Section 415(k) of the Code)
maintained by the Company, the sum of the defined benefit plan fraction and the
defined contribution plan fraction (as such terms are defined in Section 415(e)
of the Code) for any Limitation Year with respect to such Participant shall not
exceed one (1). If such sum exceeds one (1), the contributions and allocations
to the Participant's Account under this Plan shall be reduced (prior to the
reduction of any benefit of such Participant under such defined benefit plan),
as necessary, to obtain compliance with Section 415(e) of the Code. Any such
reduction under this Plan shall be made only to the extent necessary so that the
sum of such fractions shall equal one (1). For purposes of this Section 7.6, a
plan is deemed to be maintained by the Company if the plan is maintained by any
Related Company.

          (f) If a Participant is entitled to receive an allocation under this
Plan and any Related Plan and, in the absence of the limitations contained in
this Section 7.6, the Company would contribute or allocate to the Account of
that Participant an amount for a Limitation Year that would cause the Annual
Additions to the Account of the Participant to exceed the Maximum Permissible
Amount for such Year, then the contributions and 

                                      -49-
<PAGE>
 
allocations made with respect to the Participant under this Plan shall not be
reduced until the contributions and allocations under the Related Plan have been
reduced to the extent necessary so that the allocation of such Annual Additions
does not exceed the Maximum Permissible Amount.

          (g) The provisions of this Section shall be interpreted by the
Company, in the administration of the Plan, to reduce allocations (as required
by this Section) only to the minimum extent necessary to reflect the
requirements of Section 415 of the Code, as amended and in force from time to
time, and Treasury Regulations promulgated pursuant to said Section, which are
incorporated by reference herein.

          7.7  Vesting.  Subject to subsection 3.5(d), each Participant shall
               -------                                                         
at all times be fully vested in the Adjusted Balance of his Account under the
Plan.

          7.8  Allocations and Adjustments to Account.  As of each Valuation
               --------------------------------------                         
Date, and subject to Section 11.4(e), the Company shall determine, on an accrual
basis of accounting, the Adjusted Balance of each Account of each Participant in
the following manner:

          (a) As soon as practicable after each Valuation Date, the Company
shall determine the earnings and the amount of any realized or unrealized
appreciation or depreciation in the fair market value of each of the Investment
Funds, determined as of the Valuation Date or the next previous business day if
the Valuation Date falls on Saturday, Sunday or holiday.  In determining such
value 

                                      -50-
<PAGE>
 
the Company shall use such generally accepted methods and bases as the Company,
in its discretion, shall deem advisable. The judgment of the Company as to the
fair market value of any asset shall be presumptively conclusive and binding on
all persons.

          (b) The earnings on all contributions made hereunder that have been
initially invested in short term investment obligations selected by the Trustee
from time to time pending allocation to one or more of the Investment Funds
shall be allocated to a Participant's applicable Account in the same proportion
as such contributions are allocated.  The amount of such earnings on such
contributions shall be determined by multiplying the total amount of such
earnings by a fraction the numerator of which is the amount of such
contributions allocated to a Participant's Account for that Valuation Period and
the denominator of which is the total amount of such contributions allocated to
all Participants' Accounts for that Valuation Period.

          (c) The earnings and market appreciation or depreciation of each
Investment Fund for a Valuation Period (including earnings and appreciation or
depreciation attributable to the investment of any Suspense Account in such
Investment Fund) shall be allocated to each applicable Account (excluding any
Suspense Account) that is invested in such Investment Fund on the current
Valuation Date by multiplying the earnings and market appreciation or
depreciation of such Fund by a fraction the numerator of which is the Adjusted

                                      -51-
<PAGE>
 
Balance of such Account invested in the applicable Fund as of the prior
Valuation Date and the denominator of which is the total of the Adjusted
Balances of all such Accounts (excluding any Suspense Account) invested in such
Fund as of the prior Valuation Date (subtracting for purposes of determining
such fraction all distributions, withdrawals and loans made from any such
Account during such Valuation Period). Each such Account (excluding any Suspense
Account) shall be adjusted by adding thereto or subtracting therefrom its share
of the earnings and market appreciation or depreciation of each Investment Fund
as determined by the preceding sentence.

          (d) Each Account shall then be further adjusted by adding to it the
amount of contributions allocable thereto for each Participant pursuant to
Sections 7.3, 7.4 and 7.5 during the Valuation Period ending on that Valuation
Date, and subtracting therefrom all distributions, withdrawals and loans from
such Account during such Valuation Period.

Employee in a covered classification (as described in Section 2.1) thereafter
shall continue to share in the allocation of Matching Contributions and Salary
Deferral Contributions and may elect or continue to enter into Long-Term Savings

Agreements.  Upon the termination of employment with the Company and all Related
Companies of a Participant for any reason other than death, the Company shall
notify the Trustee in writing of the Participant's termination and shall direct
the Trustee to make payment in a method provided in the Plan of the Adjusted
Balance (reduced by any security interest held by the Plan by reason of a loan
outstanding to the Participant as of the date of his termination of employment
pursuant to Article XI) of the Participant's Account as of the Valuation Date
immediately preceding the date of payment, in accordance with Section 8.3.

          8.2  Payments on Death.  (a) Upon the death of a Participant the
               -----------------                                            
Company shall promptly notify the Trustee in writing of the Participant's death
and the name of his Beneficiary (or Surviving Spouse if paragraph (c) is
applicable) and shall direct the Trustee to make payment, in a method provided
in the Plan, of the Adjusted Balance (reduced by any security interest held by
the Plan by reason of a loan outstanding to the Participant as of the date of
his death pursuant to Article XI) of the Participant's Account as of the
Valuation Date immediately preceding the date of payment to his Beneficiary or
Surviving Spouse, as the case may be, in accordance with Section 8.3.

          (b) Each Participant who is not married to a Surviving Spouse at the
date of his death, or each married Participant whose Surviving Spouse has
consented to an alternate Beneficiary designation or alternate method of payment
as provided in paragraph (c) shall have the right to designate, by giving a
written 

                                      -53-
<PAGE>
 
designation to the Company, (i) a person or persons or entity as Beneficiary to
receive the death benefit provided under this Section 8.2 and (ii) the method of
payment of such death benefit to his Surviving Spouse or Beneficiary pursuant to
Section 8.3. Successive designations may be made, and the last designation
received by the Company prior to the death of the Participant shall be effective
and shall revoke all prior designations. If a designated Beneficiary shall die
before the Participant, his interest shall terminate and, unless otherwise
provided in the Participant's designation, if such designation named more than
one Beneficiary, such interest shall be paid in equal shares to those
Beneficiaries, if any, who survive the Participant. A Participant to whom this
paragraph applies shall have the right to designate different Beneficiaries to
receive the Adjusted Balance in the Participant's Savings Account, Transfer
Account and Voluntary Contribution Account under the Plan. The Participant shall
have the right to revoke the designation of any Beneficiary without the consent
of the Beneficiary.

          (c) The Beneficiary of each married Participant shall be the Surviving
Spouse of each Participant and the death benefits of any Participant who is
married at the date of his death shall be paid in full to his Surviving Spouse
in a single lump sum. Notwithstanding the preceding sentence, the death benefits
provided pursuant to paragraph (a) shall be distributed to any other Beneficiary
designated by a married Participant as provided in paragraph (b) and pursuant to
the method, if any, designated by the Participant as provided in paragraph (b),
if the Participant's Surviving Spouse consented to such designation by the

                                      -54-
<PAGE>
 
Participant, prior to the date of the Participant's death, in writing. Such
consent must acknowledge the effect of such an election, the identity of any 
non-Surviving Spouse Beneficiary, including any class of Beneficiaries or
contingent Beneficiaries, and the consent must be witnessed by a Plan
representative or a notary public. The consent of a Participant's Surviving
Spouse shall not be required if the Participant establishes to the satisfaction
of the Company that consent may not be obtained because there is no Surviving
Spouse, the Surviving Spouse cannot be located, or because of such other
circumstances as the Secretary of the Treasury may prescribe by regulations. The
Participant may not subsequently change the method of distribution elected by
the Participant or the designation of his Beneficiary unless his Surviving
Spouse consents to the new election or designation in accordance with the
requirements set forth in the preceding sentence, or unless the Surviving
Spouse's consent permits the Participant to change the election of method of
payment or the designation of his Beneficiary without the Spouse's further
consent. A Surviving Spouse's consent shall be irrevocable. Any consent by a
Surviving Spouse, or establishment that the consent of the Surviving Spouse may
not be obtained, shall be effective only with respect to that Surviving Spouse.

          (d) If a Participant shall fail to designate a Beneficiary, or if such
designation shall for any reason be illegal or ineffective, or if no Beneficiary
shall survive the Participant, his death benefits otherwise payable pursuant to
this Section shall be paid:

                                      -55-
<PAGE>
 
          (i)  to his Surviving Spouse;

          (ii) if there is no Surviving Spouse, to his descendants (including
               legally adopted children or their descendants) per stirpes;
                                                              ----------- 

         (iii) if there is neither Surviving Spouse nor surviving descendants,
               to the duly appointed and qualified executor or other personal
               representative of the Participant to be distributed in accordance
               with the Participant's will or applicable intestacy law; or

          (iv) in the event that there shall be no such representative duly
               appointed and qualified within six (6) months after the date of
               death of such deceased Participant, then to such persons as, at
               the date of his death, would be entitled to share in the
               distribution of such deceased Participant's personal estate under
               the provisions of the applicable statute then in force governing
               the descent of intestate property, in the proportions specified
               in such statute.

          (e) The Company may determine the identity of the distributees and in
so doing may act and rely upon any information that it may deem reliable upon
reasonable inquiry, and upon any affidavit, certificate, or other paper believed
by it to be genuine, and upon any evidence believed by it sufficient.

          8.3  Manner and Timing of Payment.  (a) Whenever the Company shall
               ----------------------------                                   
direct the Trustee to make payment to a Participant, his Beneficiary, or his
Surviving Spouse upon termination of the Participant's employment (whether by
reason of death, or for other reasons), the Company shall direct the Trustee to
pay the Adjusted Balance (reduced by any security interest held by the Plan by
reason of a loan outstanding to the Participant as of the date of his
termination of employment or death pursuant to Article XI) of his Account,
determined as of the Valuation Date immediately preceding the date of payment,
to or for the benefit of the Participant, his Beneficiary, or his Surviving
Spouse, in cash or wholly or partly in kind, in either of the following ways as
the Participant (or, if a deceased former Participant shall have failed to
select a method of payment, as his Beneficiary or Surviving Spouse) shall
determine:

          (i)  In a lump sum; provided that distributions in kind shall be
               valued at the fair market value of the assets distributed on the
               date of such distribution; or

          (ii) In monthly installments payable in substantially equal amounts,
               continuing over a period not longer than the lesser of (A) ten
               (10) years, or (B) the maximum period permitted under paragraph
               (c) below.

          (b) Payment under paragraph (a) next above shall be made or commence
not more than sixty (60) days after the close of the Plan Year in which 

                                      -57-
<PAGE>
 
the employment of the Participant terminates. Notwithstanding the foregoing, if
on the last day of the Plan Year corresponding to or following the date of a
Participant's termination of employment, the total amount payable under
paragraph (a) (excluding amounts distributable from his Transfer Account)
exceeds $3,500, no part of such amount may be distributed prior to the earlier
of (i) April 1 following the year in which the Participant attains age 70 1/2,
or (ii) the date of his death without the written consent of the Participant.

          (c) Notwithstanding anything to the contrary contained elsewhere in
the Plan:

          (i)  The payment of benefits under the Plan to any Participant will:
               (A) be distributed to him not later than the Required
     Distribution Date (as defined in paragraph (c)(iii)), or

               (B) be distributed commencing not later than the Required
     Distribution Date in accordance with regulations prescribed by the
     Secretary of the Treasury over a period not extending beyond the life
     expectancy of the Participant or the life expectancy of the Participant and
     his Beneficiary.

          (ii) (A) If the Participant dies after distribution to him has
     commenced pursuant to paragraph (c)(i)(B) but before his entire interest in
     the Plan has been distributed to him, then the remaining portion of that

                                      -58-
<PAGE>
 
     interest will be distributed at least as rapidly as under the method of
     distribution being used under paragraph (c)(i)(B) at the date of his death.

          (B) If the Participant dies before distribution to him has commenced
pursuant to paragraph (c)(i)(B), then, except as provided in paragraphs
(c)(ii)(C) and (c)(ii)(D), his entire interest in the Plan will be distributed
within five years after his death.

          (C) Notwithstanding the provisions of paragraph (c)(ii)(B), if the
Participant dies before distribution to him has commenced pursuant to paragraph
(c)(i)(B) and if any portion of his interest in the Plan is payable (I) to or
for the benefit of a Beneficiary, (II) in accordance with regulations prescribed
by the Secretary of the Treasury over a period not extending beyond the life
expectancy of the Beneficiary, and (III) beginning not later than one year after
the date of the Participant's death or such later date as the Secretary of the
Treasury may prescribe by regulations, then the portion of his interest referred
to in this paragraph (c)(ii)(C) shall be treated as distributed on the date on
which such distributions begin.

          (D) Notwithstanding the provisions of paragraphs (c)(ii)(B) and
(c)(ii)(C), if the Beneficiary referred to in paragraph (c)(ii)(C) is the
Surviving Spouse of the Participant, then

                                      -59-
<PAGE>
 
               (I)  the date on which the distributions are required 
                    to begin under paragraph (c)(ii)(C)(III) of this 
                    Section shall not be earlier than the date on which 
                    the Participant would have attained age 70 1/2, and

               (II) if the Surviving Spouse dies before the distributions 
                    to that Spouse begin, then this paragraph (c)(ii)(D) 
                    shall be applied as if the Surviving Spouse were the 
                    Participant.

        (iii)  For purposes of this paragraph (c), the Required Distribution
               Date means April 1 of the calendar year following the calendar
               year in which the Participant attains age 70 1/2; provided,
               however, that in the case of a Participant who attained age 
               70 1/2 during calendar year 1988 or 1989, the Required
               Distribution Date means April 1, 1990, and further provided that,
               if the Participant attained age 70 1/2 prior to January 1, 1988,
               distribution shall commence on the April 1 following the later of
               the calendar year in which he (A) attained age 70 1/2 or (B)
               terminated employment with the Company, unless he was a

                                      -60-
<PAGE>
 
               five percent owner (as defined in Section 416 of the Code) of the
               Company with respect to the Plan Year ending in the calendar year
               in which he attained age 70 1/2, in which case clause (B) shall
               not apply.

          (iv) For purposes of this paragraph (c), the life expectancy of a
Participant and his Surviving Spouse may be redetermined, but not more
frequently than annually.

          (v)  A Participant may not elect a form of distribution providing for
payments after the Participant's death to a Beneficiary who is other than his
Surviving Spouse unless the actuarial value of the payments expected to be made
to the Participant during his lifetime is more than 50% of the actuarial value
of the total payments expected to be made under such form of distribution.

          (d)  (i)  This subsection (d) applies to distributions made from the
               Plan 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 subsection, 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.

                                      -61-
<PAGE>
 
          (ii)  Definitions.

          (A)   "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 for net unrealized
appreciation with respect to employer securities).

          (B)   "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 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.

          (C)   "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

                                      -62-
<PAGE>
 
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.

          (D) "Direct Rollover" is a payment by the Plan to the Eligible
Retirement Plan specified by the Distributee.

        (iii)  Notwithstanding the above, no Direct Rollover shall be made
               pursuant to this subsection (d) (A) if the Eligible Rollover
               Distributions made during the Plan Year with respect to a
               Participant are reasonably expected to total less than $200; or
               (B) if only a portion of the Eligible Rollover Distribution is to
               be distributed as a Direct Rollover, the amount of such Direct
               Rollover is less than $500.

          (e) If a distribution is one to which Sections 401(a)(11) and 417 of
the Code do not apply, such distribution may commence less than 30 days after
the notice required under Section 1.411(a)-11(c) of the Income Tax Regulations
is given, provided that:

          (i)  the Committee clearly informs the Participant that the
               Participant has a right to a period of at least 30 days after
               receiving the notice to consider the decision of whether or not
               to elect a distribution (and, if applicable, a particular
               distribution option), and

                                      -63-
<PAGE>
 
          (ii) the Participant, after receiving the notice, affirmatively elects
               a distribution.

          8.4  Hardship Distributions.  The Company may, in its sole
               ----------------------                                 
discretion, upon the request of a Participant at any time prior to his
termination of employment, direct the Trustee to make a lump sum distribution of
a portion of the balance of the Participant's Savings Account, for the purposes
set forth below, subject to the following rules:

          (a) Each request for a distribution must be made by written
application to the Company supported by such evidence as the Company may
require;

          (b) The amount distributed to a Participant in accordance with this
Section 7.4 shall not exceed that portion of the Adjusted Balance of his Savings
Account that (i) is not derived from optional contributions under Section
3.4(d)(ii), and (ii) is not being used as security for a loan made under Article
XI, determined as of the Valuation Date coinciding with or immediately following
the date a request is made hereunder, less earnings allocated to the
Participant's Savings Account on or after December 31, 1988; provided, however,
that in no event shall the amount available for distribution pursuant to this
Section 8.4 be less than the Adjusted Balance of the Participant's Savings
Account on December 31, 1988, less the amount being used as security for a loan
made under Article XI, determined as 

                                      -64-
<PAGE>
 
of the Valuation Date coinciding with or immediately following the date a
request is made hereunder;

          (c) The Company shall direct the Trustee to make a distribution to a
Participant in accordance with this Section 8.4 only in the event of the
Participant's "hardship."  For purposes of this Section, a hardship shall be
limited to:

          (i)  Medical expenses described in Code Section 213(d) previously
               incurred by the Participant, the Participant's spouse, or any
               dependents of the Participant (as defined in Code Section 152) or
               necessary for any of these persons to obtain medical care
               described in Code Section 213(d);

          (ii) Purchase (excluding mortgage payments) of a principal residence
               for the Participant;

          (iii)Payment of tuition and related educational fees for the next

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

          (v)  Funeral expenses of a family member of the Participant.

                                      -65-
<PAGE>
 
          (d) The amount distributed shall not be in excess of the immediate and
heavy financial need of the Participant which need shall be deemed to include
any amounts reasonably anticipated by the Participant to be necessary to pay
federal, state or local income taxes and penalties incurred as a result of the
distribution;

          (e) The Participant shall first obtain all distributions, other than
those on account of hardship, and all nontaxable loans available under the Plan
and all other plans maintained by the Company;

          (f) The Participant's Salary Deferral Contributions and Voluntary
Contributions under the Plan, and elective contributions and employee

for twelve (12) months after receipt of the hardship distribution (except for
mandatory employee contributions to a defined benefit plan); and

          (g) The Participant may not make Salary Deferral Contributions under
the Plan, or elective contributions under any other plan maintained by the
Company, for the Participant's taxable year immediately following the taxable
year of the hardship distribution in excess of the applicable limit under
Section 402(g) of the Code for such next taxable year, decreased by the Salary
Deferral Contributions to the Plan and elective contributions to such other
plans for the taxable year of the hardship distribution.

          8.5  Non-Hardship In-Service Distributions.  (a) A Participant who
               -------------------------------------                            
has attained the age of 59 1/2 may elect, by written instrument given to the
Company, to withdraw from his Savings Account an amount not in excess of (i) if
he has completed five (5) years of participation in the Plan, then the Adjusted
Balance thereof, determined as of the Valuation Date coinciding with or
immediately following the date the written instrument is delivered to the
Company; or (ii) if he has not completed five (5) years of participation in the
Plan, then that portion of the Adjusted Balance thereof, determined as of the

Contributions, and (B) the portion of the Matching Contributions allocated to
such Account more than two (2) years prior to the date of the election.

          (b) The amount distributed in accordance with this Section 8.5 shall

Account that is not being used as security for a loan made under Article XI,

          8.6  Withdrawals from Voluntary Contribution and Transfer Accounts.
               -------------------------------------------------------------    
As of any Valuation Date, a Participant may elect by written instrument given to
the Company, to withdraw from his Voluntary Contribution Account and Transfer
Account an amount not in excess of the Adjusted Balance thereof

                                      -67-
<PAGE>

          8.7  Rules Governing In-Service Distributions.  (a) In the event a
               ----------------------------------------                        
Participant requests to receive a distribution pursuant to Sections 8.4, 8.5 or
8.6, the distribution shall be paid to the Participant as soon as is reasonably
practicable after receipt of the written request for such distribution.  If a
Participant's termination of employment occurs after an election is made in
accordance with those Sections, but prior to distribution of the full amount
elected, such election shall be automatically void and the benefits he or his
Surviving Spouse or Beneficiary are entitled to receive under the Plan shall be
distributed in accordance with the other provisions of this Article.

          (b) No distribution made pursuant to Sections 8.4, 8.5 or 8.6 may be
for an amount which is less than the lesser of: (i) $200; or (ii) that portion
of the Adjusted Balance of the Participant's Savings Account, Voluntary
Contribution Account or Transfer Account (whichever is applicable) which is
subject to withdrawal pursuant to such Section.

          (c) A Participant may not make more than two withdrawals pursuant to
each of Sections 8.4, 8.5 and 8.6 in any Plan Year.

          8.8  Distribution of Unallocated Contributions.  (a) If on the date
               -----------------------------------------                       
of termination of a Participant's employment, the Company shall be holding
Voluntary Contributions or a Rollover Contribution made by the Participant, but

                                      -68-
<PAGE>
 
not yet allocated to his Voluntary Contribution Account or Transfer Account
(whichever is applicable), the Company shall pay such amounts either directly to
the Participant (or his Beneficiary or Surviving Spouse, as the case may be) or
to the Trustee, to be distributed by the Trustee in accordance with Section 8.3.

          (b) If on the date of termination of a Participant's employment, a
Participant's Earnings have been reduced by any amount pursuant to a Long-Term
Savings Agreement, or a Matching Contribution has been made on behalf of such
Participant pursuant to Section 4.1(a), and any such amount has not yet been
allocated to his Savings Account, the Company shall pay such amounts to the
Trustee to be credited to the Participant's Savings Account, to be distributed
by the Trustee in accordance with Section 8.3.

          8.9  Administrative Powers Relating to Payments.  If a Participant,
               ------------------------------------------                      
Beneficiary, or Surviving Spouse, is under a legal disability or, by reason of
illness or mental or physical disability, is in the opinion of the Company
unable properly to attend to his personal financial matters, the Trustee may
make such payments in such of the following ways as the Company shall direct:

          (a) directly to such Participant, Beneficiary, or Surviving Spouse;

          (b) to the legal representative of such Participant, Beneficiary, or
Surviving Spouse; or

                                      -69-
<PAGE>
 
          (c) to some relative by blood or marriage, or friend, for the benefit
of such Participant, Beneficiary or Surviving Spouse.

Any payment made pursuant to this Section shall be in complete discharge of the
obligation therefor under the Plan.

          8.10  Distributions From Savings Accounts.  Notwithstanding anything
                -----------------------------------                             
to the contrary contained elsewhere in the Plan, a Participant's Savings Account
shall not be distributable other than upon:

          (a) the Participant's separation from service, death or disability;

          (b) termination of the Plan without establishment or maintenance of
another defined contribution plan (other than an employee stock ownership plan
as defined in Section 4975(e)(7) of the Code);

          (c) the date of the sale or other disposition by the Company to an
unrelated entity of substantially all of the assets (within the meaning of
Section 409(d)(2) of the Code) used by the Company in a trade or business of the
Company, where (i) the Participant is employed by such trade or business and
continues employment with the entity acquiring such assets, and (ii) the Company
continues to maintain the Plan after the sale or other disposition.  The sale of
85% of the assets used in a trade or business shall be deemed to be a
disposition of "substantially all" of the assets used in such trade or business;

                                      -70-
<PAGE>
 
          (d) the date of the sale or other disposition by the Company of the
Company's interest in a subsidiary (within the meaning of Section 409(d)(3) of
the Code) to an unrelated entity, where (i) the Participant is employed by such
subsidiary and continues employment with such subsidiary following such sale or
other disposition, and (ii) the Company continues to maintain the Plan after the
sale or other disposition;

          (e) the Participant's attainment of age 59 1/2; or

          (f) the Participant's hardship (as defined in, and in accordance with
the provisions of, Section 8.4).

          Notwithstanding anything to the contrary contained herein, an event
shall not be treated as described in clause (b), (c) or (d) above unless the
Participant receives a lump sum distribution (as defined in Section
401(k)(10)(B)(ii) of the Code) by reason of the event.  Nothing in this Section
is intended to expand the instances in which distributions may be made to
Participants.  This Section is included in the Plan solely to set forth the
restrictions of Section 401(k) of the Code.

          9.1  Company Responsibility and Establishment of Committee. (a) The
               -----------------------------------------------------            
Company shall be responsible for and shall control and manage the operation and
administration of the Plan.  It shall be the "Plan Administrator" and "Named
Fiduciary" for purposes of ERISA and shall be subject to service of process on
behalf of the Plan.

          (b) The Company may, in its discretion, appoint or designate employees
or agents as the Committee to act on behalf of the Company in performing its
duties. The members of the Committee shall serve at the pleasure of the Board of
Directors of the Company and may be officers, directors or Employees of the
Company or any other individuals. The members of the Committee shall serve
without compensation for such. Any member may resign by delivering his written
resignation to the Board and to the Committee. Vacancies in the Committee
arising by resignation, death, removal or otherwise shall be filled by the
Board. The Company shall advise the Trustee in writing of the names of the
Committee and of changes in membership from time to time.

          (c) The Committee shall act by majority vote of its members at the
time in office, and such action may be taken either by a vote at a meeting or in
writing without a meeting.  The signatures of a majority of the members will be

                                      -72-

sufficient to authorize Committee action.  The Committee may authorize any of
its members or any other person to execute any document or documents on behalf
of the Committee, in which event the Committee shall notify the Trustee in
writing of such action and the name or names of such member or person.  The
Trustee thereafter shall accept and rely upon any document executed by such
members or persons as representing action by the Committee, until the Committee
shall file with the Trustee a written revocation of such designation.

          (d) The Committee may adopt such bylaws and regulations as it deems
desirable for the conduct of its affairs and may appoint such accountants,
counsel, specialists, and other persons as it deems necessary or desirable in
connection with the administration of the Plan. The Committee shall be entitled
to rely conclusively upon, and shall be fully protected in any action taken by
it in good faith in relying upon, any opinions or reports which shall be
furnished to it by any such accountant, counsel, specialist or other person.

          (e) If the Company shall designate an Employee who is a Participant to
act on behalf of the Company in administering the Plan and exercising fiduciary
responsibilities with respect to the Plan, such Participant shall not in such
capacity participate in discussions of, or in decisions relating to, matters
pertaining to his own participation in the Plan or to any distributions or loans
made to him under the Plan.

          9.2  Powers and Duties of Committee.  The Committee shall administer
               ------------------------------                                   
the Plan in accordance with its terms and shall have all powers necessary to
carry out the provisions of the Plan.  The Committee shall direct the Trustee
concerning all payments that shall be made out of the Trust pursuant to the
Plan.  The Committee shall interpret the Plan and shall determine all questions
arising in the administration, interpretation, and application of the Plan all
in the sole discretion of the Committee, including but not limited to, questions
of eligibility and the status and rights of Participants, Beneficiaries,
Surviving Spouses and other persons.  Any such determination by the Committee
shall presumptively be conclusive and binding on all persons.  The regularly
kept records of the Committee shall be conclusive and binding upon all persons
with respect to an Employee's age, date and length of employment, time and
amount of Compensation and Earnings and the manner of payment thereof', type and
length of any absence from work and all other matters contained therein relating
to Employees.  All rules and determinations of the Committee shall be uniformly
and consistently applied to all persons in similar circumstances.

          9.3  Records and Reports of Committee.  The Committee shall keep all
               --------------------------------                                 
such books of account, records, and other data as may be necessary for proper
administration of the Plan.  The Committee shall notify the Trustee of any
action taken by the Committee and, when required, shall notify any other
interested person or persons.

made in writing to the Committee. In the event a claim for benefits is wholly or
partially denied by the Committee, the Committee shall, within a reasonable
period of time, but no later than ninety (90) days after receipt of the claim,
notify the claimant in writing of the denial of the claim. If the claimant shall
not be notified in writing of the denial of the claim within ninety (90) days
after it is received by the Committee, the claim shall be deemed denied. A
notice of denial shall be written in a manner calculated to be understood by the
claimant, and shall contain (a) the specific reason or reasons for denial of the
claim, (b) a specific reference to the pertinent Plan provisions upon which the
denial is based, (c) a description of any additional material or information
necessary for the claimant to perfect the claim, together with an explanation of
why such material or information is necessary, and (d) an explanation of the
Plan's review procedure. Within sixty (60) days of the receipt by the claimant
of the written notice of denial of the claim, or within sixty (60) days after
the claim is deemed denied as set forth above, if applicable, the claimant may
file a written request with the Committee that it conduct a full and fair review
of the denial of the claimant's claim for benefits, including the conducting of
a hearing, if deemed necessary by the Committee. In connection with the
claimant's appeal of the denial of his benefit, the claimant may review
pertinent documents and may submit issues and comments in writing. The Committee
shall render a decision on the claim appeal promptly, but not later than sixty
(60) days after the receipt of the claimant's request for review, unless special
circumstances (such as the need to hold a hearing, if necessary), require an

                                      -75-
<PAGE>
 
extension of time for processing, in which case the sixty (60) day period may be
extended to one hundred and twenty (120) days. The Committee shall notify the
claimant in writing of any such extension. The decision upon review shall (a)
include specific reasons for the decision, (b) be written in a manner calculated
to be understood by the claimant and (c) contain specific references to the
pertinent Plan provisions upon which the decision is based.

          9.5  Expenses.  All proper expenses incurred by the Committee
               --------                                                  
incident to the functioning of the Plan shall be paid by the Company; provided,
however, that expenses and fees incurred in connection with the investment of
Plan assets, unusual costs and expenses of litigation involving the Plan and
losses, if any, of the Plan of any kind or character, shall be deemed expenses
of the Plan and shall be borne by the Plan, and paid out of the Plan assets,
except to the extent the Board elects to have such expenses paid directly by the
Company.

to make a loan or loans to active Participants, and, to the extent not
inconsistent with Section 401(a) of the Code, to former Participants who are
Parties in Interest (as defined in Section 3(14) of ERISA) and who retain
Account balances in the Plan following termination of employment ("Former
Participants"), applied for pursuant to the terms of this Article XI.  Such loan
or loans shall be in an amount or amounts that do not in the aggregate exceed
the amount set forth in Section 11.2 below.  No more than one such loan may be
outstanding from the Plan and the Hourly Plan (as defined in Section 5.3(b)) to
any Participant at any time.  Loans shall be made on the written application of
the Participant to the Committee and on such terms and 

                                      -77-

conditions as are set forth in this Article. In making such loans, the Committee
shall pursue uniform policies and shall not discriminate in favor of or against
any Participant or group of Participants.

          (b) Each borrowing Participant or Former Participant shall, as a
condition to receiving a loan hereunder, specify in his loan application the
Investment Funds in which his Savings Account is invested from which such loan
shall be paid and the allocation of the loan proceeds among such Investment
Funds; provided, that such allocation shall be in increments of one percent
(1%). Each such loan shall be made in accordance with the specification of the
borrowing Participant or Former Participant except that, if any Investment Fund
imposes any restriction or penalty on a distribution as a loan, the loan shall
be paid from the Investment Funds in such manner as will comply with such
restriction and avoid such penalty.

          (c) The Committee may impose such additional uniform and
nondiscriminatory requirements upon Participants and Former Participants
applying for loans as the Committee may determine.

          11.2  Maximum Loan Amount.  (a) In no event shall any loan made
                -------------------

amount that shall cause the outstanding aggregate balance of all loans made to
such Participant or Former Participant under this Plan and all other qualified
plans (as defined in Section 72(p)(4)(A) of the Code without regard to
subparagraph (2)(D) 

                                      -78-

of:

          (i)  $50,000, reduced by the excess (if any) of:

          (A) the highest outstanding balance of loans from the Plan and such
other qualified plans to the Participant or Former Participant during the one-
year period ending on the day before the date such loan is made, over

          (B) the outstanding balance of loans from the Plan and such other
qualified plans to the Participant or Former Participant on the date on which
such loan is made; or

          (ii) fifty percent (50%) of the Adjusted Balance of the Participant's
               or Former Participant's Savings Account.

          (b) For purposes of this Article, the Adjusted Balance of the Savings
Account of the Participant or Former Participant shall be determined as of the
Valuation Date for which a valuation of his Savings Account is most recently
available on the date on which the proceeds of a loan made under this Article
are disbursed to the borrowing Participant.

          11.3  Repayment of Loans.  Any loan made under this Article shall

made, except that a loan to a Participant or a Former Participant used to
acquire any dwelling unit that within a reasonable time after the loan is made
is to be used

(determined at the time the loan is made) as the principal residence of the
Participant or Former Participant shall mature and be payable in full within ten
(10) years after the date such loan is made.

          11.4  Terms.  (a) Loans to Participants and Former Participants
                -----                                                      
shall be made according to the following terms:

          (i)  the minimum principal amount of any loan, at the time it is made,
               shall be $ 1,000.

          (ii) proceeds of the loan shall be disbursed to a Participant or
               Former Participant no later than sixty (60) days after he has
               applied for the loan in accordance with procedures established by
               the Committee;

          (iii)the loan shall be adequately secured, provided that such
               minimum security for such loans shall be (A) not more than 50% of
               the Adjusted Balance of the Savings Account of the borrowing
               Participant or Former Participant, plus (B) a security interest
               in such other property, determined by the Committee, that would
               be required in the case of an otherwise identical transaction in
               a normal commercial setting between unrelated parties on arm's-
               length terms;

                                      -80-
<PAGE>
 
          (iv) interest shall he determined by the Committee at the time the
               loan is made and shall be charged at a rate that is commensurate
               with the interest rate charged by persons in the business of
               lending money for a loan that would be made under similar
               circumstances in the local geographical area;

          (v)  payments of principal and interest by an active Participant shall
               be made through payroll deductions, which deductions shall be
               irrevocably authorized by the borrowing Participant in writing on
               a form supplied by the Committee at the time the loan is made to
               him, and such payroll deductions shall be sufficient to amortize
               the principal and interest payable pursuant to the loan during
               the term thereof in equal quarterly (or more frequent)
               installments.  In the case of a Former Participant, payments of
               principal and interest shall be made by personal payment in
               quarterly or more frequent installments according to procedures
               established by the Committee.  All payments of principal and
               interest shall be allocated to the Savings Account of the
               Participant or Former Participant to whom the loan was made;

          (vi) the borrowing Participant or Former Participant shall have the
               right to prepay all (but not a portion) of the interest and
               principal of such loan without penalty;

                                      -81-
<PAGE>
 
         (vii) the loans shall be evidenced by such forms of obligations, and
               shall be made upon such additional terms as to default,
               prepayment, security and otherwise as the Committee shall
               determine;

        (viii) the Committee may charge a borrowing Participant or Former
               Participant such reasonable administrative fees with respect to
               each loan as the Committee shall, in its discretion, decide; and

          (ix) if the borrowing Participant or Former Participant is married at
               the time for disbursement of the loan proceeds, disbursement may
               not be made unless such Participant's or Former Participant's
               spouse consents in writing to the loan and the terms thereof
               pursuant to procedures established by the Committee.

          (b) The entire unpaid balance of any loan made under this Article and
all interest due thereon, including all arrearages thereon, shall, at the option
of the Committee, immediately become due and payable without further notice or
demand, if, with respect to the borrowing Participant or Former Participant, any
of the following events of default occurs:

                                      -82-
<PAGE>
 
          (i)  any payment of principal and/or accrued interest on the loan
               remains due and unpaid for a period of thirty (30) days after the
               same becomes due and payable under the terms of the loan;

          (ii) a proceeding in bankruptcy, receivership or insolvency is
               commenced by or against the borrowing Participant or Former
               Participant;

         (iii) an active Participant's employment with the Company is
               terminated for any reason and he does not become a Former
               Participant (except to the extent inconsistent with Section
               401(a) of the Code);

          (iv) the borrowing Participant becomes a Former Participant and
               thereafter receives a final distribution of the Adjusted Balance
               of his Savings Account (except to the extent inconsistent with
               Section 401(a) of the Code);

          (v)  the borrowing Participant or Former Participant attempts to make
               an assignment, for the benefit of creditors of the Adjusted
               Balance of his Savings Account under the Plan or of any other
               Security for the loan; or

          (vi) the borrowing Participant or Former Participant marries or
               remarries and his new spouse does not consent in writing to the
               loan and the terms thereof pursuant to procedures established by
               the Committee within thirty days after marrying the Participant.

<PAGE>
 
Any payments of principal and/or interest on the loan not paid when due shall
bear interest thereafter, to the extent permitted by law, at the rate specified
by the terms of the loan.  The payment and acceptance of any sum or sums at any
time on account of the loan after an event of default, or any failure to act or
enforce the rights granted hereunder upon an event of default, shall not be a
waiver of the right of acceleration set forth in this paragraph.

          (c) If an event of default and an acceleration of the unpaid balance
of the loan and interest due thereon shall occur, the Committee shall have the
right to direct the Trustee to pursue any remedies available to a creditor at
law or under the terms of the loan, including the right to execute on the
security for the loan; provided, however, that neither the Trustee nor the
Committee may reduce the amount in the Participant's Savings Account at any time
prior to the first to occur of the termination of the Participant's employment
with the Company or the Participant's attainment of age 59 1/2.

          (d) Each such loan shall be a first lien against the Savings Account
of the borrowing Participant or Former Participant.  If: (i) any portion of a
loan shall be outstanding; and (ii) an event occurs pursuant to which the
Participant, Former Participant, or his estate, or his Surviving Spouse or
Beneficiaries will 

                                      -84-
<PAGE>
 
receive a distribution from the Savings Account of such Participant or Former
Participant under the provisions of the Plan, then such Participant or Former
Participant, if living, shall pay to the Trustee an amount equal to the portion
of the loan or loans then outstanding, including all accrued interest thereon,
and such Participant or Former Participant shall then receive the full amount of
the distribution under the provisions of the Plan to which he is otherwise
entitled. If such Participant or Former Participant is not then living, or if
such Participant or Former Participant does not make full payment of the portion
of the loan or loans then outstanding by the next date repayment would have been
made through payroll deduction had the event pursuant to which the distribution
is to be made not occurred, or in the case of a Former Participant, within 30
days after the date of such event, then such distribution shall, to the extent
necessary to liquidate the unpaid portion of the loan or loans, be made to the
Trustee as payment on the loan or loans. No distribution shall be made to a
Participant, or Former Participant, or his estate or his Surviving Spouse or
Beneficiaries from his Savings Account in an amount greater than the excess of
the portion of his Savings Account otherwise distributable over the aggregate of
the amounts owing with respect to such loan or loans plus interest, if any,
thereon, taking into consideration any portion of the loan or loans paid by the
Participant or Former Participant pursuant to the provisions of this paragraph
(d).

          (e) All loans made pursuant to this Article shall be funded from the
borrowing Participant's or Former Participant's Savings Account as set forth in

Section 11.1(b). The Savings Account of a Participant or Former Participant
shall, to the extent used to fund such loan, not participate in the allocation
of earnings and losses pursuant to Section 7.8. All interest paid by a
Participant or Former Participant with respect to a loan shall be credited to
the borrowing Participant's or Former Participant's Savings Account and shall
not be allocated pursuant to Section 6.8 as earnings of the Investment Funds.
All payments of principal and interest made by a Participant or Former
Participant with respect to a loan shall be allocated to one or more of the
Investment Funds based upon the form relating to the selection of Investment
Funds which is in effect, at the time such payment is received by the
Trustee, with respect to the Participant's or Former Participant's Salary
Deferral Contributions.  If such a form is not in effect at the time such
payment is received, the payments shall be allocated based upon the last such
form that was in effect for such Participant or Former Participant.  If no such
form was in effect at any time, such payment shall be allocated equally among
all of the Investment Funds described in the schedule attached to the Trust
Agreement.

Matching Contributions, Voluntary Contributions, and Rollover Contributions
received by the Trustee will be initially invested, from the date received until
the date invested under Section 12.3, in such short term investment obligations
as selected by the Trustee from time to time.  These deposits and earnings will
be allocated among the Investment Funds as of the Valuation Date next following
receipt by the Trustee of such deposits and earnings in accordance with
Participants' selection of Investment Funds pursuant to Section 12.3.

file a form with the Committee directing that his Salary Deferral Contributions,
Matching Contributions, Voluntary Contributions and Rollover Contributions be
invested, in specified multiples of 10%, in any one of the Investment Funds. No

in paragraph (a) above (in specified multiples of 10%) with respect to
subsequent Salary Deferral Contributions, Matching Contributions, Voluntary
Contributions and Rollover Contributions under the Plan.

          (c) Each Participant shall have the right to file a written form with
the Committee directing that the portion of his Savings Account, Transfer
Account and Voluntary Contribution Account held in any one Investment Fund be
transferred, in whole or in part, to any other Investment Fund.  This direction
shall be made by designating the percentage, number of shares or amount of the
Adjusted Balance of such Accounts that is to be divided among the various
applicable Funds (in percentages, numbers of shares or amounts) as of the date
set forth in paragraph (d) next below.

          (d) Any form filed by a Participant pursuant to this Section shall be
filed with the Committee pursuant to rules it establishes.  A form filed
pursuant to subsection (a) of this Section shall be filed at the same time as
the Long-Term Savings Agreement required pursuant to Section 2.3.  A form filed
pursuant to subsection (b) of this Section shall be filed no later than (i) the
tenth day of the month in which the Wage Payment Date as of which it is to be
effective occurs, in the case of a salaried Participant or (ii) the tenth day of
the month preceding the month in which the Wage Payment Date as of which it is
to be effective occurs, in the case of an hourly paid Participant. A form filed

on any business day, shall be forwarded by the Committee to the Trustee within
five business days after receipt thereof, and shall be effective on the next
business day following the day on which it is received by the Trustee. A
modification pursuant to paragraph (b) may be made only once in each month. A
transfer pursuant to paragraph (c) may be made only once in each calendar
quarter and shall be subject to any additional nondiscriminatory restrictions
that are imposed by the Trustee.

          (e) The Company will separately account for the interests of each
Participant in the several Investment Funds.  Each Investment Fund may be
invested as a single fund, however, without segregation of Fund assets to
represent the interests of Participants.

the Plan at any time and from time to time by resolution of the Board, and the
Company and all persons claiming any interest hereunder shall be bound thereby;
provided, however, that no amendment shall have the effect of: (i) directly or
indirectly divesting the interest of any Participant in any amount that he would
have received had he terminated his employment with the Company immediately
prior to the effective date of such amendment, or the interest of any
Beneficiary or Surviving Spouse as such interest existed immediately prior to
the effective date of such amendment; (ii) directly or indirectly affecting the
vested interest of a Participant under the Plan as determined by Section 7.7
unless the conditions of Section 203(c) of ERISA are satisfied; (iii) vesting in
the Company any right, title or interest in or to any Trust assets; (iv) causing
or effecting discrimination in favor of officers, shareholders, or highly
compensated Employees; or (v) causing any part of the Plan assets to be used for
any purpose other than for the exclusive benefit of the Participants and their
Beneficiaries and Surviving Spouse.

          13.2  Voluntary Termination of or Permanent Discontinuance of
                -------------------------------------------------------
Contributions to the Plan.  The Company expects the Plan to be permanent, but
- -------------------------                                                      
since future conditions affecting the Company cannot be anticipated, the Company
shall have the right to terminate the Plan in whole or in part, or to
permanently 

                                      -90-

discontinue contributions to the Plan, at any time by resolution of its Board
and by giving written notice of such termination or permanent discontinuance to
the Trustee. Such resolution shall specify the effective date of termination or
permanent discontinuance, which shall not be earlier than the first day of the
Plan Year that includes the date of the resolution.

          13.3  Involuntary Termination of Plan.  The Plan shall automatically
                -------------------------------                                 
terminate if the Company is legally adjudicated a bankrupt, makes a general
assignment for the benefit of creditors, or is dissolved.  In the event of the
merger or consolidation of the Company into or with any other corporation,
respectively, or in the event substantially all of the assets of the Company
shall be transferred to another corporation, the successor corporation resulting
from the consolidation or merger, or transfer of such assets, as the case may
be, shall have the right to adopt and continue the Plan and succeed to the
position of the Company hereunder. If, however, the Plan is not so adopted
within ninety (90) days after the effective date of such consolidation, merger
or sale, the Plan shall automatically be deemed terminated as of the effective
date of such transaction. Nothing in this Plan shall prevent the dissolution,
liquidation, consolidation or merger of the Company, or the sale or transfer of
all or substantially all of its assets.

          13.4  Payments on Termination of, or Permanent Discontinuance of

Company contributions to the Plan, the following procedure shall be followed,
except that in

the event of a partial termination it shall be followed only in case of those
Participants, Beneficiaries and Surviving Spouses directly affected:

          (a) The Company may continue to administer the Plan, but if it fails
to do so, its records, books of account and other necessary data shall be turned
over to the Trustee and the Trustee shall act on its own motion as hereinafter
provided.

          (b) Notwithstanding any other provisions of the Plan all interests of
Participants shall continue to be fully vested and nonforfeitable.

          (c) The value of the Trust Fund and the Accounts of all Participants,
Beneficiaries and Surviving Spouses shall be determined as of the date of
termination or discontinuance.

          (d) Distribution to Participants, Beneficiaries and Surviving Spouses
shall be made at such time after termination of or discontinuance of
contributions to the Plan as provided in Section 8.3 above and not later than
the time specified in Section 8.3.

their Beneficiaries and Surviving Spouses must furnish to the Company and the
Trustee such evidence, data or information as the Company considers necessary or

Company shall provide each Participant, and each former Participant and
Beneficiary or Surviving Spouse with respect to whom an Account is maintained,

Adjusted Balance thereof.  No Participant, except a member of the Board or the
Committee, shall have the right to inspect the records reflecting the Account of

Plan shall be construed as a contract of employment between the Company and any

          14.4  Applicable Law.  All questions pertaining to the validity,

payment of any benefits which may be or become due to any person from the Trust
Fund.  No Participant or other person shall have any recourse against the
Trustee, the Company or the Committee if the Trust Fund is insufficient to
provide Plan benefits in full.  Nothing herein contained shall be deemed to give
any Participant, former Participant, Beneficiary or Surviving Spouse an interest
in any specific part of the Trust Fund or any other interest except the right to
receive benefits out of the Trust Fund in accordance with the provisions of the
Plan and Trust.

          14.6  Unclaimed Funds.  Each Participant shall keep the Company

                                      -94-

shall be obligated to search for the whereabouts of any person. If the location
of a Participant is not made known to the Company within three (3) years after
the date on which distribution of the Participant's accounts may first be made,
distribution may be made as though the Participant had died at the end of the
three-year period. If, within one additional year after such three year period
has elapsed, or, within three years after the actual death of a Participant, the
Company is unable to locate any individual who would receive a distribution
under the Plan upon the death of the Participant pursuant to Section 8.2 of the
Plan, the Adjusted Balance in the Participant's Account shall be deemed a
forfeiture and shall be used to reduce Matching Contributions to the Plan for
the Plan Year next following the year in which the forfeiture occurs and for
succeeding years to the extent necessary; provided, however, that in the event
that the Participant or a Beneficiary or Surviving Spouse makes a valid claim
for any amount that has been forfeited, the benefits which have been forfeited
shall be reinstated.

other plan, shall be effected in accordance with such regulations, if any, as
may be issued pursuant to Section 208 of ERISA, in such a manner that each
Participant in the Plan would receive, if the merged, consolidated or transferee
plan were terminated immediately following such event, a benefit that is equal
to or greater than the benefit he would have been entitled to receive if the
Plan had terminated immediately before such event.

XI of the Plan, no interest of any person or entity in, or right to receive
distributions from, the Trust Fund shall be subject in any manner to sale,
transfer, assignment, pledge, attachment, garnishment, or other alienation or
encumbrance of any kind; nor may such interest or right to receive distributions
be taken, either voluntarily or involuntarily, for the satisfaction of the debts
of, or other obligations or claims against, such person or entity, including
claims for alimony, support, separate maintenance and claims in bankruptcy
proceedings. The Account of any Participant, however, shall be subject to and
payable in accordance with the applicable requirements of any qualified domestic
relations order, as that term is defined in Section 414(p) of the Code, and the
Company shall direct the Trustee to provide for payment from a Participant's
Account in accordance with such order and with the provisions of Section 414(p)
of the Code and any regulations promulgated thereunder. A payment from a
Participant's Account may be made to an alternate payee (as defined in Section
414(p)(8) of the Code) prior to the date the Participant reaches his earliest
retirement age (as defined in Section 414(p)(4)(B) of the Code) if such payments
are made pursuant to a qualified domestic relations order. All such payments
pursuant to a qualified domestic relations order shall be subject to reasonable
rules and regulations promulgated by the Company respecting the time of payment
pursuant to such order and the valuation of the Participant's Account from which
payment is made; provided, that all such payments are made in accordance with
such order and Section 414(p) of the Code. The balance of an

Account that is subject to any qualified domestic relations order shall be
reduced by the amount of any payment made pursuant to such order.

          (b) Notwithstanding paragraph (a) next above, if any Participant
borrows money pursuant to Article X of the Plan, the Trustee and the Company
shall have all rights to collect upon such indebtedness as are granted pursuant
to Article XI of the Plan and any agreements or documents executed in connection
with such loan.

Plan and the Trust Agreement, the Trustee and the Company shall exercise their
powers and discharge their duties under the Plan and the Trust Agreement for the
exclusive purpose of providing benefits to Employees and their Beneficiaries and
Surviving Spouses, and shall act with the care, skill, prudence and diligence
under the circumstances that a prudent man acting in a like capacity and
familiar with such matters would use in the conduct of an enterprise of a like
character and with like aims.  Subject to the terms of the preceding sentence
and the provisions of Article XII, the Trustee shall diversify investments of
the Trust Fund so as to minimize the risk of large losses, unless under the
circumstances it is clearly prudent not to do so.

          14.10  Limitations on Liability.  Notwithstanding any other

employee or

agent of any of them, shall be liable to any Participant, former Participant,
Beneficiary, or Surviving Spouse for any claim, loss, liability or expense
incurred in connection with the Plan or the Trust, except when the same shall
have been judicially determined to be a result of liability under Part 4 of
Title I of ERISA or due to the gross negligence or willful misconduct of such
person. The Company shall indemnify and hold harmless each Trustee, Committee
member, employee of the Company, or any individual acting as an employee or
agent of any of them or the Company (to the extent not indemnified or held
harmless under any liability insurance or any other indemnification arrangement
with respect to the Plan or the Trust) from any and all claims, losses,
liabilities, costs and expense (including attorneys' fees) arising out of any
actual or alleged act or failure to act with respect to the administration of
the Plan or the Trust, except that no indemnification or defense shall be
provided to any person with respect to conduct which has been judicially
determined, or agreed by the parties, to have constituted bad faith or willful
misconduct on the part of such person, or to have resulted in his receipt of
personal profit or advantage to which he is not entitled. In connection with the
indemnification provided by the preceding sentence, expenses incurred in
defending a civil or criminal action, suit or proceeding, or incurred in
connection with a civil or criminal investigation, may be paid by the Company in
advance of the final disposition of such action, suit, proceeding, or
investigation, as authorized by the Board in the specific case, upon receipt of
an undertaking by or on behalf of the party to be indemnified to repay such
amount, unless it shall ultimately be 

                                      -98-

determined that he is entitled to be indemnified by the Company pursuant to this
Section. The preceding provisions of this Section shall not apply to any claims,
losses, liabilities, costs and expenses arising out of any actual or alleged act
or failure to act of a Participant, or any individual acting as an employee or
agent of a Participant, in the selection of investment media for his Account, or
the investment of the assets in his Account.

intended to qualify as a Plan and Trust meeting the requirements of Sections 401
and 501(a) of the Code, as now in effect or hereafter amended, so that the
income of the Trust Fund may be exempt from taxation under Section 501(a) of the
Code, contributions of the Company under the Plan may be deductible for Federal
income tax purposes under Section 404 of the Code, and amounts subject to Long-
Term Savings Agreements are not treated as distributed to Participants for
Federal income tax purposes under Section 402(a)(8) of the Code, all as now in
effect or hereafter amended. Any modification or amendment of the Plan and/or
Trust may 

                                      -99-

be made retroactively, as necessary or appropriate, to establish and maintain
such qualification and to meet any requirement of the Code or ERISA.

          14.14  Exclusive Benefit of Employees.  All contributions made
                 ------------------------------                           
pursuant to the Plan shall be held by the Trustee in accordance with the terms
of the Trust Agreement for the exclusive benefit of those Employees who are
Participants under the Plan, including former Participants and their
Beneficiaries and Surviving Spouses, and shall be applied to provide benefits
under the Plan and to pay expenses of administration of the Plan and the Trust,
to the extent that such expenses are not otherwise paid.  At no time prior to
the satisfaction of all liabilities with respect to such Employees and their
Beneficiaries shall any part of the Trust Fund (other than such part as may be
required to pay administration expenses and taxes), be used for, or diverted to,
purposes other than for the exclusive benefit of such Employees and their
Beneficiaries and Surviving Spouses.  However, without regard to the provisions
of this Section 14.14:

          (a) If any contribution under the Plan is conditioned on initial
qualification of the Plan under Section 401(a) of the Code and if the Plan
receives an adverse determination with respect to its initial qualification, the
Trustee shall, upon written request of the Company, return to the Company the
amount of such contribution (increased by earnings attributable thereto and
reduced by losses attributable thereto) within one calendar year after the date
that qualification of the Plan is denied, provided that the application for the
determination is made by

                                     -100-
<PAGE>
 
the time prescribed by law for filing the Company's return for the taxable year
in which the Plan is adopted, or such later date as the Secretary of the
Treasury may prescribe;

          (b) If a contribution is conditioned upon the deductibility of the
contribution under Section 404 of the Code, then, to the extent the deduction is
disallowed, the Trustee shall, upon written request of the Company, return the
contribution (to the extent disallowed) to the Company within one year after the
date the deduction is disallowed;

          (c) If a contribution or any portion thereof is made by the Company by
a mistake of fact, the Trustee shall, upon written request of the Company,
return the contribution or such portion to the Company within one year after the
date of payment to the Trustee; and

          (d) Earnings attributable to amounts to be returned to the Company
pursuant to paragraph (b) or (c) above shall not be returned, and losses
attributable to amounts to be returned pursuant to paragraph (b) or (c) above
shall reduce the amount to be so returned.

          14.15  Adoption of Plan by Related Companies.  (a) With the approval
                 -------------------------------------                          
of the Company, any Related Company may adopt the Plan and qualify its employees
to become Participants hereunder by taking proper corporate action to adopt the
Plan (which action shall designate the class or classes of such employees 

                                     -101-
<PAGE>
 
to be covered by the Plan) and making such contributions to the Trust Fund as
the Board of Directors of the Related Company may require.

          (b) The Plan will terminate with respect to any Related Company that
has adopted the Plan pursuant to this Section if the Related Company ceases to
be a Related Company, revokes its adoption of the Plan by appropriate corporate
action, permanently discontinues its contributions for its Employees, is
judicially declared bankrupt, makes a general assignment for the benefit of
creditors, or is dissolved.  If the Plan is terminated or contributions are
discontinued with respect to any Related Company, the provisions of Section 13.4
shall apply to the interest in the Plan of the Employees of such Related
Company, and their Beneficiaries and Surviving Spouses.

          (c) The references to "Company" and "Employee" in the Plan shall
include any Related Company that has adopted the Plan pursuant to this Section
14.15 and such Related Company's Employees; provided, however, that the
references to "Company" and "Employee" shall not include any such Related
Company or its Employees in Section 2.1 (except in the first and second
sentences of such Section) and references to "Company" shall not include any
such Related Company in Articles IX or XIII of the Plan.  The Company shall act
as the agent for each Related Company that adopts the Plan for all purposes of
administration thereof.

          14.16  Severability.  Each of the Sections contained in the Plan,
                 ------------                                                
and each provision in each Section, shall be enforceable independently of every
other Section or provision in the Plan, and the invalidity or nonenforceability
of any Section or provision shall not invalidate or render nonenforceable any
other Section or provision contained herein. If any Section or provision in a
Section is found invalid or unenforceable, it is the intent of the parties that
a court of competent jurisdiction shall reform the Section or provision to
produce its nearest enforceable economic equivalent.

                                  ARTICLE XV

                             TOP-HEAVY PROVISIONS
                             --------------------

          15.1  Top-Heavy Status.  The provisions of this Article shall not
                ----------------                                              
apply to the Plan with respect to any Plan Year for which the Plan is not Top-
Heavy.  If the Plan is or becomes Top-Heavy in any Plan Year, the provisions of
this Article XV will supersede any conflicting provisions elsewhere in the Plan.

          15.2  Definitions.  For purposes of this Article XV, the following
                -----------                                                   
words and phrases shall have the meanings stated below unless a different
meaning is plainly required by the context:

          (a) "Determination Date" means, with respect to any Plan Year: (i) the
last day of the preceding Plan Year, or (ii) in the case of the first Plan Year
of the Plan, the last day of such Plan Year.

                                     -103-
<PAGE>
 
          (b) "Key Employee" means an Employee meeting the definition of "key
employee" contained in Section 416(i)(1) of the Code and the Treasury
Regulations interpreting that Section.  For purposes of determining whether an
Employee is a Key Employee, the definition of Compensation set forth in Section
15.5 shall apply.

          (c) "Non-key Employee" means any Employee who is not a Key Employee.

          (d) "Valuation Date" means with respect to a particular Determination
Date, the most recent Valuation Date (as defined in Section 1.41) occurring
within a twelve-month period ending on the applicable Determination Date.

          15.3  Determination of Top-Heavy Status.  (a) The Plan will be
                ---------------------------------                          
"Top-Heavy" with respect to any Plan Year if, as of the Determination Date
applicable to such Year, the ratio of the Adjusted Balances in the Accounts of
Key Employees (determined as of the Valuation Date applicable to such
Determination Date) to the Adjusted Balances in the Accounts of all Employees
(determined as of such Valuation Date) exceeds 60%.  For purposes of computing
such ratio, and for all other purposes of applying and interpreting this
paragraph (a):  (i) the amount of the Account of any Employee shall be increased
by the aggregate distributions made with respect to such Employee under the Plan
during the five-year period ending on any Determination Date; (ii) benefits
provided under all plans that are 

                                     -104-
<PAGE>
 
aggregated pursuant to (b) of this Section must be considered; and (iii) the
provisions of Section 416 of the Code and all regulations and other governmental
releases interpreting that Section shall be applied. If any Employee has not
performed services for the Company or any Related Company at any time during the
five-year period ending on any Determination Date, the balance of the Account of
such Employee shall not be taken into consideration for purposes of determining
whether the Plan is Top-Heavy with respect to the Plan Year to which such
Determination Date applies.

          (b) For purposes of determining whether the Plan is Top-Heavy, all
qualified retirement plans maintained by the Company and each Related Company
shall be aggregated to the extent that such aggregation is required under the
applicable provisions of Section 416 of the Code and the Treasury Regulations
and other governmental releases interpreting that Section.  All other qualified
retirement plans maintained by the Company and each Related Company shall be
aggregated only to the extent permitted by Section 416 of the Code and such
Treasury Regulations and other governmental releases and elected by the Company.

          (c) For purposes of determining whether the Plan is Top-Heavy, the
Adjusted Balance of a Participant's Account shall not include (i) the amount of
a Rollover Contribution (or similar transfer) and earnings thereon attributable
to a Rollover Contribution (or similar transfer) accepted after December 31,
1983, 

                                     -105-
<PAGE>
 
initiated by the Participant and derived from a plan not maintained by the
Company or any Related Company, or (ii) a distribution made with respect to an
Employee that is a tax-free Rollover Contribution (or similar transfer) that is
either not initiated by the Employee or that is made to a plan maintained by the
Company or any Related Company.

          (d) Solely for purposes of determining whether the Plan is Top-Heavy,
the accrued benefit of any Non-key Employee shall be determined (i) under the
method, if any, that uniformly applies for accrual purposes under all plans of
the Company or any Related Company, or (ii) if there is no such method, as if
such benefit accrued not more rapidly than the slowest accrual rate permitted
under the fractional accrual rule of Section 411(b)(1)(C) of the Code.

          15.4  Minimum Contribution.  For each Plan Year that the Plan is
                --------------------                                        
Top-Heavy, the Company will contribute and allocate to the Savings Account of
each Eligible Employee who is a Non-key Employee and is employed by the Company
on the last day of such Plan Year an amount equal to the lesser of (i) 3% of
such Participant's Compensation (as defined in Section 15.5) for such Plan Year
and (ii) the largest percentage of Company contributions and forfeitures, as a
percentage of the Key Employee's Compensation (as defined in Section 15.5),
allocated to the Savings Account of any Key Employee for such Plan Year.  The
minimum contribution allocable pursuant to this Section 15.4 will be determined
without regard to any contributions by the Company for any Employee under the
Federal Social Security Act.  A Non-key Employee will not be excluded from an

                                     -106-
<PAGE>
 
allocation pursuant to this Section merely because his compensation is less than
a stated amount.  A Non-key Employee who has become a Participant but who fails
to complete at least 1,000 Hours of Service in a Plan Year in which the Plan is
Top-Heavy shall not be excluded from an allocation pursuant to this Section.  A
Non-key Employee who is a Participant in the Plan and who declined to elect to
have Salary Deferral Contributions made to his Account for the Plan Year shall
receive an allocation for that Plan Year pursuant to this Section.  For purposes
of clause (ii) of the first sentence of this Section, the amount of Company
contribution allocated to the Savings Account of a Key Employee for a Plan Year
shall include Salary Deferral Contributions allocated to the Savings Account of
such Key Employee for such Year.

          15.5  Compensation.  For any Plan Year in which the Plan is Top-
                ------------                                               
Heavy, annual Compensation for the purposes of this Article shall have the
meaning set forth in Section 414(q)(7) of the Code.  The Compensation of a
Participant taken into account for purposes of this Article XV for the Plan
Years commencing on and after January 1, 1989 shall be limited in accordance
with the provisions of subsections 1.12(e) through (h) of the Plan.

          15.6  Limit on Annual Additions:  Combined Plan - Limit.  (a) If
                -------------------------------------------------            
the Plan is determined to be Top-Heavy under Section 15.3, Section 7.6(d) shall
be applied by substituting "1.0" for "1.25" in applying Section 415(e) of the
Code to the Plan.

                                     -107-
<PAGE>
 
          (b) Paragraph (a) above shall not apply if:

               (i)  Section 15.4 is applied by substituting "4%" for "3%," and

          (c) If, but for this paragraph (c), paragraph (a) would begin to apply
with respect to the Plan, the operation of paragraph (a) shall be suspended with
respect to an Employee as long as there are:

               (i)  no Company contributions, forfeitures or voluntary non-
                    deductible contributions allocated with respect to such
                    Employee, and

               (ii) no accruals under a qualified defined benefit plan for such
                    Employee.

          15.7  Safe-Harbor Rule.  If this Plan is Top-Heavy in any Plan
                ----------------                                           
Year, each Non-Key Employee covered under both a Top-Heavy defined benefit plan
and a Top-Heavy defined contribution plan maintained by the Company or any
Related Company, and under this Plan, shall receive the defined benefit minimum
(as defined in Section 416(c)(1) of the Code) under the provisions of the
defined benefit plan, and shall not receive the minimum contribution under
Section 15.4 of this Plan, for such Year.

               Participant does not make full payment of the portion of the loan
               or loans then outstanding by the next date repayment would have

               of a Former Participant within 30 days after the date of such
               event, then such distribution shall, to the extent necessary to
               liquidate the unpaid portion of the loan or loans, be made to the

               a Surviving Spouse or Beneficiaries from his Savings Account or
               Transfer Account in an amount greater than the excess of the
               portion of his Savings Account and Transfer Account otherwise
               distributable over the aggregate of the amounts owing with
               respect to such loan or loans, plus interest, if any, thereon,
               taking into consideration any portion of the loan or loans paid
               by the Participant or Former Participant pursuant to the
               provisions of this paragraph (d).

          (e)  All loans made pursuant to this Article shall be funded from the
               borrowing Participant's or Former Participant's Savings Account
               and Transfer Account as set forth in Section 11.1(b).  The
               Savings Account and Transfer Account of a Participant or a Former
               Participant shall, to the extent used to fund such loan, not
               participate in the allocation of earnings and losses pursuant to
               Section 7.8.  All interest paid by a Participant or Former
               Participant with respect to a loan shall be credited to the
               borrowing Participant's or Former Participant's Savings Account
               and Transfer Account, and shall not be allocated pursuant to
               Section 6.8 as earnings of the Investment Fund.  All payments of
               principal and interest made by a Participant or Former
               Participant with respect to a loan shall be allocated to any one
               or more of the Investment Funds based upon the form relating to
               the selection of Investment Funds which is in effect at the time
               such payment is received by the Trustee, with respect to the
               Participant's or Former Participant's Salary Deferral
               Contributions.  If such a form is not in effect at the time such
               payment is received, the payment shall be allocated based upon
               the last form that was in effect for such Participant or Former
               Participant. If no such form was in effect at any time, such
               payment shall be allocated equally among all of the Investment
               Funds described in the schedule attached to the Trust Agreement.

     IN WITNESS WHEREOF, the Company has caused this Amendment I to the Plan to
be executed in its name by a duly authorized officer, this 5 day of March, 1996,
effective as of the 1st day of January, 1996.

                                   EMPLOYEES

          WHEREAS, Illinois Consolidated Telephone Company (the "Company")
adopted the Illinois Consolidated Telephone Company Long-Term Savings Plan for
Salaried and Affiliated Employees, as amended and restated effective January 1,
1989 ("Plan");

          WHEREAS, the Company wishes to amend the Plan to authorize the
contribution of McLeodUSA Incorporated Class A common stock as a matching
contribution under the Plan;

          WHEREAS, the Company having the power to amend the Plan, now deems it
appropriate to amend the Plan in certain respects;

          NOW THEREFORE, BE IT RESOLVED, that the Plan is amended, effective
January 1, 1998 as follows:

          1.  Section 4 is amended by the addition of a new Section 4.l(g) to
read as follows:

          (g) Effective January 1, 1998, the Company may from time to time make
Matching Contributions to the Trust in the form of McLeodUSA Incorporated Class
A common stock (or other securities of the Company or Related Company).  The
securities contributed to the Plan under this Section 4.l(g) shall be held in a
separate Fund and shall be adjusted for gains, incomes, losses and expenses in
accordance with Section 7.8.  Notwithstanding any other provision of the Plan to
the contrary, distribution of the Adjusted Balance of a Participant's Account
under the Plan shall not include a distribution of the securities contributed
under this Section 4.1(g).  Whenever a Participant, his Beneficiary or his
Surviving Spouse become entitled to a distribution under Article 8, the Trustee
shall sell, at no less 

                                     -118-

than fair market value, the portion of the Participant's Account attributable to
the contributions (including allocable earnings) made under this Section 4.1(g)
and distribute the proceeds in accordance with Article 8.

          2.  In all other respects not amended, the Plan is ratified.

          IN WITNESS WHEREOF, the Company has caused this Amendment III to the
Plan to be executed in its name by a duly authorized officer, this 8th day of
January, 1998, effective as of January 1, 1998.

of all documents submitted to us as originals, and the authenticity, accuracy
and completeness and conformity with the original documents of all documents
submitted to us as certified, telecopied, photostatic, or reproduced copies. We

Company having received the consideration therefor, the form of which is in
accordance with applicable law), will be validly issued, fully paid and non-
assessable by the Company.

subsequent to the delivery of this opinion letter.  This opinion letter has been
prepared solely for your use in connection with the filing of the Registration
Statement on the date of this letter, and should not be quoted in whole or in
part or otherwise be referred to, nor be filed with or furnished to any
governmental agency or other person or entity, without the prior written consent
of this firm.

          We hereby consent to the filing of this opinion letter as Exhibit 5.1
to the Registration Statement.  In giving this consent, we do not thereby admit
that we are an "expert" within the meaning of the Securities Act of 1933, as
amended.

                                    Very truly yours,
