     The following statements are summaries of certain provisions with respect
to the Common Stock of the Company contained in the Company's Articles of
Incorporation, as amended, as affected by certain rights of holders, if any, of
the Company's Preferred Stock (including the holders of Series A Preferred and
the Series B Preferred).  Such statements, which do not purport to be complete,
are subject in all respects to the full provisions of the Company's Articles of
Incorporation, as amended (including, without limitation, the Certificates of
Designations describing the the rights and preferences of the holders of the
Series A Preferred and the Series B Preferred).

COMMON STOCK
- ------------

     Holders of Common Stock are entitled to one vote per share in the election
of directors and on all other matters submitted to a vote at a meeting of
shareholders.  As discussed below, holders of the Series A Preferred are
entitled to vote (on an as-converted basis) together with the holders of Common
Stock on all matters coming before the holders of Common Stock, and, upon the
occurrence of certain events, the holders of the Series A Preferred may be
entitled to have exclusive rights regarding the election of one director.  As
discussed below, the holders of the Company's Series B Preferred Stock have
certain exclusive rights regarding the election of three of the Company's
directors.  With the exception of votes with regard to the other directors of
the Company, the holders of the Series B Preferred are entitled to vote (on an
as-converted basis) together with the holders of Common Stock on all matters
coming before the holders of Common Stock. Cumulative voting for the election of
directors is not permitted.

     Subject to the rights of any then outstanding shares of Preferred Stock,
holders of the Common Stock are entitled to such dividends as may be declared in
the discretion of the Board of Directors out of funds legally available
therefor.  As described in more detail below, accrued and unpaid dividends of
the holders of the Series A Preferred and Series B Preferred must be paid prior
to the payment of dividends to the holders of the Common Stock.  Holders of the
Common Stock are entitled to share ratably in the net assets of the Company upon
liquidation after payment or provision for all liabilities and any preferential
liquidation rights of any Preferred Stock then outstanding.  As indicated below,
the holders of the Series A Preferred and Series B Preferred have preferential
liquidation rights.  The holders of Common Stock have no preemptive rights to
purchase shares of stock of the Company.  Shares of Common Stock are not subject
to any redemption provisions and are not convertible into any other securities
of the Company. All outstanding shares of the Common Stock are fully paid and
nonassessable. Continental Stock Transfer & Trust Company is the transfer agent
and registrar for the Common Stock.

PREFERRED STOCK
- ---------------

     The Preferred Stock may be issued from time to time by the Board of
Directors as shares of one or more classes or series.  Subject to the provisions
of the Company's Articles of Incorporation and limitations prescribed by law,
the Board of Directors is expressly authorized to adopt resolutions to issue the
shares, to fix the number of shares and to change the number of shares
constituting any series, and to provide for or change the voting powers,
designations, preferences and relative, participating, optional or other special
rights, qualifications, limitations or restrictions thereof, including dividend
rights (including whether dividends are cumulative), dividend rates, terms of
redemption (including sinking fund provisions), redemption prices, conversion
rights and liquidation preferences of the shares constituting any class or
series of the Preferred Stock, in each case without any further action or vote
by the stockholders.

                                       3
<PAGE>
 
     SERIES A PREFERRED

     The Company has designated 26,000 shares of Preferred Stock as Series A
Preferred Stock. The Series A Preferred provides for quarterly, cumulative
dividends that accrue at the rate of (i) $8.00 per share per annum for the
period beginning on the date of issuance and ending on June 30, 2001; (ii)
$10.00 per share per annum for the period beginning July 1, 2001 and ending on
June 30, 2002; (iii) $12.00 per share per annum for the period beginning July 1,
2002 and ending on June 30, 2003, and (iv) $16.00 per share per annum after July
1, 2004, and shall be first payable on June 30, 1999 (subject to certain
extensions). Payment of such dividends shall be in preference and priority to
any dividends paid to holders of the Common Stock and on parity with the holders
of the Series B Preferred Stock. The Series A Preferred is convertible into
shares of Common Stock at a rate equal to that amount to be received for each
share of Series A Preferred in liquidation ($100 per share plus accrued but
unpaid dividends) divided by a factor of $3.50 (subject to adjustment). Each
holder of the Series A Preferred is entitled to voting rights with respect to
any matters put before the Company's stockholders, in an amount of votes equal
to the number of whole shares into which the shares of Series A Preferred are
convertible at the time of such vote. In addition, the consent of the holders of
two-thirds of the Series A Preferred, voting as a class, is necessary for the
Company to sell all or substantially all of its assets or effect any merger,
consolidation or share exchange. If shares of the Series A Preferred are
outstanding after June 30, 2001, the Company's board of directors shall be
increased by one, and the holders of such shares, voting as a separate class,
shall be entitled to elect a director to fill such newly created directorship.
Upon the liquidation of the Company, the holders of the Series A Preferred and
Series B Preferred are entitled to receive liquidation proceeds in an amount
equal to $100 per share, plus any accrued and unpaid dividends, on a parity
basis, prior to any distributions being made to the holders of any other class
of the Company's stock.

     SERIES B PREFERRED

     The Company has designated 400,000 shares of Preferred Stock as Series B
Preferred.  The Series B Preferred provides for quarterly, cumulative dividends
that accrue at the rate of $9.00 per share (subject to adjustment) per annum.
Payment of such dividends shall be in preference and priority to any dividends
paid to holders of the Common Stock and on parity with the holders of the Series
A Preferred.  At the option of the Company, such dividends may be paid by the
Company with additional shares of the Series B Preferred. The Series B Preferred
is convertible into shares of Common Stock at a rate equal to that amount to be
received for each share of Series B Preferred in liquidation ($100 per share
plus accrued but unpaid dividends) divided by a factor of $6.00 (subject to
adjustment).  The holders of the Series B Preferred may convert the Series B
Preferred to Common Stock at the then established conversion rate at any time.
The Company may force the holders of the Series B Preferred to convert to Common
Stock at the then established conversion rate at any time after the fifth
anniversary of the issuance of the Series B Preferred. Except with respect to
the election of directors, each holder of the Series B Preferred is entitled to
voting rights with respect to any matters put before the Company's stockholders,
in an amount of votes equal to the number of whole shares into which the shares
of Series B Preferred are convertible at the time of such vote. The holders of
the Series B Preferred, acting as a class, have the exclusive right to elect
three of the Company's directors, but do not vote on an "as converted" basis in
the election of the remaining directors. Upon a breach by the Company of certain
financial covenants, the holders of the Series B Preferred, acting as a class,
can elect a majority of the directors of the Company. In addition, the consent
of the holders of a majority of the Series B Preferred, voting as a class, is
necessary for the Company to (i) make or commit to any capital expenditures (a)
exceeding $1.0 million for purposes other than the affiliation with physician
practice groups and (b) exceeding $10.0 million in total consideration for an
affiliation with any physician practice group, (ii) make any change in the
capital structure of the Company (including debt financings), or (iii) merge or
consolidate
                                       4
<PAGE>
 
with or into or transfer all or substantially all of its assets to any person or
entity. A majority of the holders of the Series B Preferred, acting as a class,
have the right to designate two of the three members of the Company's
Acquisitions and Budget Committee of the Board of Directors, which committee
controls the Company's investments in affiliation agreements with physician
practices and other entities. The Company has also agreed to maintain certain
financial ratio covenants in conjunction with the Series B Preferred. Upon the
liquidation of the Company, the holders of the Series A Preferred and Series B
Preferred are entitled to receive liquidation proceeds in an amount equal to
$100 per share plus any accrued and unpaid dividends, on a parity basis, prior
to any distributions being made to the holders of any other class of the
Company's stock.


ITEM 5.   INTERESTS OF NAMED EXPERTS AND COUNSEL.

               Not Applicable.

ITEM 6.   INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     The Articles of Incorporation of the Company, together with its Bylaws,
provide that the Company shall indemnify officers and directors, and may
indemnify its other employees and agents, to the fullest extent permitted by
law.  The laws of the State of Texas permit, and in some cases require,
corporations to indemnify officers, directors, agents and employees who are or
have been a party to or are threatened to be made a party to litigation against
judgments, fines, settlements and reasonable expenses under certain
circumstances.

     The Company has also adopted provisions in its Articles of Incorporation
that limit the liability of its directors  to the fullest extent permitted by
the laws of the State of Texas.  Under the Company's Articles of Incorporation,
and as permitted by the laws of the State of Texas, a director is not liable to
the Company or its shareholders for damages for breach of fiduciary duty.  Such
limitation of liability does not affect liability for (i) breach of the
director's duty of loyalty to the corporation or its shareholders, (ii) acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of the law, (iii) any transaction from which the director derived an
improper personal benefit, or (iv) the payment of any unlawful dividends.

     Texas corporations also are authorized to obtain insurance to protect
officers and directors from certain liabilities, including liabilities against
which the corporation cannot indemnify its directors and officers. The Company
has purchased and maintains a directors' and officers' liability policy for such
purposes.

ITEM 7.   EXEMPTION FROM REGISTRATION CLAIMED.

ITEM 9.   UNDERTAKINGS.

     The undersigned registrant hereby undertakes as follows:

          (1)  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 of 1933;

               (ii)  To reflect in the prospectus any facts or events arising
          after the effective date of this registration statement (or the most
          recent post-effective amendment thereof) which, individually or in
          aggregate, represent a fundamental change in the information set forth
          in the registration statement. Notwithstanding the foregoing, any
          increase or decrease in volume of securities offered (if the total
          dollar value of securities offered would not exceed that which was
          registered) and any deviation from the low or high end of the
          estimated maximum offering range may be reflected in the form of
          prospectus filed with the Commission pursuant to Rule 424(b) if, in
          the 

                                       6
<PAGE>
 
          aggregate, the changes in volume and price represent no more than 20
          percent change in the maximum aggregate offering price set forth in
          the "Calculation of Registration Fee" table in the effective
          registration statement; and

               (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 (1)(i) and (1) (ii) above do not
          apply if 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 15(d) of the Securities
          Exchange Act of 1934 that are incorporated by reference in the
          registration statement.

          (2)  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 herein, and the offering of such securities at
               that time shall be deemed to be the initial bona fide offering
               thereof; and

          (3)  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 herein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     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 Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than 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 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.

PLAN EXECUTION

<PAGE>
 
                                  INTRODUCTION


    The Primary Employer previously established a 401(k) savings plan on January
1, 1991.

    The Primary Employer is of the opinion that the plan should be changed.  It
believes that the best means to accomplish these changes is to completely
restate the plan's terms, provisions and conditions.  The restatement, effective
April 1, 1998, is set forth in this document and is substituted in lieu of the
prior document.

    The restated plan continues to be for the exclusive benefit of employees of
the Employer.  All persons covered under the plan on March 31, 1998, shall
continue to be covered under the restated plan with no loss of benefits.

    It is intended that the plan, as restated, shall qualify as a profit sharing
plan under the Internal Revenue Code of 1986, including any later amendments to
the Code.

                                   ARTICLE I

                             FORMAT AND DEFINITIONS

SECTION 1.01--FORMAT.

    Words and phrases defined in the DEFINITIONS SECTION of Article I shall have
that defined meaning when used in this Plan, unless the context clearly
indicates otherwise.

    These words and phrases have an initial capital letter to aid in identifying
them as defined terms.

SECTION 1.02--DEFINITIONS.

    ACCOUNT means, for a Participant, his share of the Investment Fund and
    Qualifying Employer Securities Fund.  Separate accounting records are kept
    for those parts of his Account that result from:

    (a) Elective Deferral Contributions

    (b) Matching Contributions

    (c) Rollover Contributions

    If the Participant's Vesting Percentage is less than 100% as to any of the
    Employer Contributions, a separate accounting record will be kept for any
    part of his Account resulting from such Employer Contributions and, if there
    has been a prior Forfeiture Date, from such Contributions made before a
    prior Forfeiture Date.

    A Participant's Account shall be reduced by any distribution of his Vested
    Account and by any Forfeitures.  A Participant's Account will participate in
    the earnings credited, expenses charged and any appreciation or depreciation
    of the Investment Fund.  His Account is subject to any minimum guarantees
    applicable under the Group Contract or other investment arrangement.

    ACTIVE PARTICIPANT means an Eligible Employee who is actively participating
    in the Plan according to the provisions in the ACTIVE PARTICIPANT SECTION of
    Article II.

    ADOPTING EMPLOYER means an employer controlled by or affiliated with the
    Employer and listed in the ADOPTING EMPLOYERS - SINGLE PLAN SECTION of
    Article II.

    AFFILIATED SERVICE GROUP means any group of corporations, partnerships or
    other organizations of which the Employer is a part and which is affiliated
    within the meaning of Code Section 414(m) and regulations thereunder.  Such
    a group includes at least two organizations one of which is either a service
    organization (that is, an organization the principal business of which is
    performing services), or an organization the principal business of which is
    performing management functions on a regular and continuing basis.  Such
    service is of a type historically performed by employees.  In the case of a
    management organization, the Affiliated Service Group shall include
    organizations related, within the meaning of Code Section 144(a)(3), to
    either the management organization or the organization for which it performs
    management functions.  The term Controlled Group, as it is used in this
    Plan, shall include the term Affiliated Service Group.

                                       2

<PAGE>
 
    ANNUITY STARTING DATE means, for a Participant, the first day of the first
    period for which an amount is payable as an annuity or any other form.

    BENEFICIARY means the person or persons named by a Participant to receive
    any benefits under this Plan upon the Participant's death.  See the
    BENEFICIARY SECTION of Article IX.

    CLAIMANT means any person who has made a claim for benefits under this Plan.
    See the CLAIM AND APPEAL PROCEDURES SECTION of Article VIII.

    CODE means the Internal Revenue Code of 1986, as amended.

    COMPENSATION means, except as modified in this definition, the total
    earnings paid or made available to an Employee by the Employer during any
    specified period.

    "Earnings" in this definition means Compensation as defined in the
    CONTRIBUTION LIMITATION SECTION of Article III.

    Compensation shall also include elective contributions.  Elective
    contributions are amounts excludable from the Employee's gross income under
    Code Sections 125, 402(e)(3), 402(h) or 403(b), and contributed by the
    Employer, at the Employee's election, to a Code Section 401(k) arrangement,
    a simplified employee pension, cafeteria plan or tax-sheltered annuity.
    Elective contributions also include Compensation deferred under a Code
    Section 457 plan maintained by the Employer and Employee contributions
    "picked up" by a governmental entity and, pursuant to Code Section
    414(h)(2), treated as Employer contributions.

    For purposes of the EXCESS AMOUNTS SECTION of Article III, the Employer may
    elect to use an alternative nondiscriminatory definition of Compensation in
    accordance with the regulations under Code Section 414(s).

    For purposes of determining the amount of Elective Deferral Contributions,
    Compensation shall exclude reimbursements or other expense allowances,
    fringe benefits (cash and noncash), moving expenses, deferred compensation
    and welfare benefits.

    For Plan Years beginning after December 31, 1988, and before January 1,
    1994, the annual Compensation of each Participant taken into account for
    determining all benefits provided under the Plan for any year shall not
    exceed $200,000.  For Plan Years beginning on or after January 1, 1994, the
    annual Compensation of each Participant taken into account for determining
    all benefits provided under the Plan for any year shall not exceed $150,000.

    The $200,000 limit shall be adjusted by the Secretary at the same time and
    in the same manner as under Code Section 415(d).  The $150,000 limit shall
    be adjusted by the Commissioner 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 pay is determined (determination period) beginning in
    such calendar year.  If a determination period consists of fewer than 12
    months, the annual compensation limit will be multiplied by a fraction, the
    numerator of which is the number of months in the determination period, and
    the denominator of which is 12.

    In determining the Compensation of a Participant for purposes of the annual
    compensation limit, the rules of Code Section 414(q)(6) shall apply, except
    that in applying such rules, the term "family" shall include 

                                       3
<PAGE>
 
    only the spouse of the Participant and any lineal descendants of the
    Participant who have not attained age 19 before the close of the year. If,
    as a result of the application of such rules the adjusted annual
    compensation limit is exceeded, then (except for purposes of determining the
    portion of Compensation up to the integration level if this Plan provides
    for permitted disparity) the limitation shall be prorated among the affected
    individuals in proportion to each such individual's Compensation as
    determined under this definition prior to the application of this
    limitation.

    If Compensation for any prior determination period is taken into account in
    determining a Participant's benefits accruing in the current Plan Year, the
    Compensation for that prior determination period is subject to the annual
    compensation limit in effect for that prior determination period.  For this
    purpose, for determination periods beginning before the first day of the
    first Plan Year beginning on or after January 1, 1989, which are used to
    determine benefits in Plan Years beginning after December 31, 1988 and
    before January 1, 1994, the annual compensation limit is $200,000.  For this
    purpose, for determination periods beginning before the first day of the
    first Plan Year beginning on or after January 1, 1994, which are used to
    determine benefits in Plan Years beginning on or after January 1, 1994, the
    annual compensation limit is $150,000.

    Compensation means, for an Employee who is a Leased Employee, the Employee's
    Compensation for the services he performs for the Employer, determined in
    the same manner as the Compensation of Employees who are not Leased
    Employees, regardless of whether such Compensation would be received
    directly from the Employer or from the leasing organization.

    COMPENSATION YEAR means each one-year period ending on the last day of the
    Plan Year, including corresponding periods before January 1, 1991.

    CONTINGENT ANNUITANT means an individual named by the Participant to receive
    a lifetime benefit after the Participant's death in accordance with a
    survivorship life annuity.

    CONTRIBUTIONS means

        Elective Deferral Contributions
        Matching Contributions
        Rollover Contributions

    as set out in Article III, unless the context clearly indicates otherwise.

    CONTROLLED GROUP means any group of corporations, trades or businesses of
    which the Employer is a part that are under common control.  A Controlled
    Group includes any group of corporations, trades or businesses, whether or
    not incorporated, which is either a parent-subsidiary group, a brother-
    sister group, or a combined group within the meaning of Code Section 414(b),
    Code Section 414(c) and regulations thereunder and, for purposes of
    determining contribution limitations under the CONTRIBUTION LIMITATION
    SECTION of Article III, as modified by Code Section 415(h) and, for the
    purpose of identifying Leased Employees, as modified by Code Section
    144(a)(3).  The term Controlled Group, as it is used in this Plan, shall
    include the term Affiliated Service Group and any other employer required to
    be aggregated with the Employer under Code Section 414(o) and the
    regulations thereunder.

    DIRECT ROLLOVER means a payment by the Plan to the Eligible Retirement Plan
    specified by the Distributee.

                                       4
<PAGE>
 
    DISTRIBUTEE means an Employee or former Employee.  In addition, the
    Employee's or former Employee's surviving spouse and the Employee's or
    former Employee's spouse or former spouse who is the alternate payee under a
    qualified domestic relations order, as defined in Code Section 414(p), are
    Distributees with regard to the interest of the spouse or former spouse.

    EARLY RETIREMENT DATE means the first day of any month before a
    Participant's Normal Retirement Date which the Participant selects for the
    start of his retirement benefit.  This day shall be on or after the date on
    which he ceases to be an Employee and the date he meets the following
    requirement(s):

    (a) He has attained age 55.

    ELECTIVE DEFERRAL CONTRIBUTIONS means Contributions made by the Employer to
    fund this Plan in accordance with a qualified cash or deferred arrangement
    as described in Code Section 401(k).  See the EMPLOYER CONTRIBUTIONS SECTION
    of Article III.

    ELIGIBILITY BREAK IN SERVICE means an Eligibility Computation Period in
    which an Employee is credited with 500 or fewer Hours-of-Service.  An
    Employee incurs an Eligibility Break in Service on the last day of an
    Eligibility Computation Period in which he has an Eligibility Break in
    Service.

    ELIGIBILITY COMPUTATION PERIOD means a 12-consecutive month period.  The
    first Eligibility Computation Period begins on an Employee's Employment
    Commencement Date.  Later Eligibility Computation Periods shall be 12-
    consecutive month periods ending on the last day of each Plan Year that
    begins after his Employment Commencement Date.

    To determine an Eligibility Computation Period after an Eligibility Break in
    Service, the Plan shall use the 12-consecutive month period beginning on an
    Employee's Reemployment Commencement Date as if his Reemployment
    Commencement Date were his Employment Commencement Date.

    ELIGIBILITY SERVICE means one year of service for each Eligibility
    Computation Period that has ended and in which an Employee is credited with
    at least 1,000 Hours-of-Service.

    However, Eligibility Service is modified as follows:

    Predecessor Employer service included:

          An Employee's service with a Predecessor Employer shall be included as
          service with the Employer.  This service excludes service performed
          while a proprietor or partner.

    Period of Military Duty included:

          A Period of Military Duty shall be included as service with the
        Employer to the extent it has not already been credited.  For purposes
        of crediting Hours-of-Service during the Period of Military Duty, an
        Hour-of-Service shall be credited (without regard to the 501 Hour-of-
        Service limitation) for each hour an Employee would normally have been
        scheduled to work for the Employer during such period.

                                       5
<PAGE>
 
    Controlled Group service included:

          An Employee's service with a member firm of a Controlled Group while
          both that firm and the Employer were members of the Controlled Group
          shall be included as service with the Employer.

    ELIGIBLE EMPLOYEE means any Employee of the Employer.

    ELIGIBLE RETIREMENT PLAN means an individual retirement account described in
    Code Section 408(a), an individual retirement annuity described in Code
    Section 408(b), an annuity plan described in Code Section 403(a) or a
    qualified trust described in Code Section 401(a), 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.

    ELIGIBLE ROLLOVER DISTRIBUTION means 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:

    (a) 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.

    (b) Any distribution to the extent such distribution is required under Code
        Section 401(a)(9).

    (c) 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).

    EMPLOYEE means an individual who is employed by the Employer or any other

    Highly Compensated Employee who is one of the 10 most highly compensated
    Employees ranked on the basis of compensation paid by the Employer during
    such year, then the family member and the 5 percent owner or top-ten highly
    compensated Employee shall be aggregated.  In such case, the family member
    and 5 percent owner or top-ten highly compensated Employee shall be treated
    as a single Employee receiving compensation and Plan contributions or
    benefits equal to the sum of such compensation and contributions or benefits
    of the family member and 5 percent owner or top-ten highly compensated
    Employee.  For purposes of this definition, family member includes the
    spouse, lineal ascendants and descendants of the Employee or former Employee
    and the spouses of such lineal ascendants and descendants.

    Compensation is compensation within the meaning of Code Section 415(c)(3),
    including elective or salary reduction contributions to a cafeteria plan,

        layoff, jury duty, military duty or leave of absence.  Notwithstanding
        the preceding provisions of this subparagraph (b), no credit will be
        given to the Employee

            because of any single continuous period in which the Employee
            performs no duties (whether or not such period occurs in a single
            computation period); or

        (2) for an Hour-of-Service for which the Employee is directly or
            indirectly paid, or entitled to payment, because of a period in
            which no duties are performed if such payment is made or

        (3) for an Hour-of-Service for a payment which solely reimburses the
            Employee for medical or medically related expenses incurred by him.

          For purposes of this subparagraph (b), 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.

    (c) Each hour for which back pay, irrespective of mitigation of damages, is
        either awarded or agreed to by the Employer.  The same Hours-of-Service
        shall not be credited both under subparagraph (a) or subparagraph (b)
        above (as the case may be) and under this subparagraph (c).  Crediting
        of Hours-of-Service for back pay awarded or agreed to with respect to
        periods described in subparagraph (b) above will be subject to the
        limitations set forth in that subparagraph.

    determining hours of service for reasons other than the performance of
    duties such as payments calculated (or not calculated) on the basis of units
    of time and the rule against double credit.  The reference to paragraph (c)
    applies to the crediting of hours of service to computation periods.

    Hours-of-Service shall be credited for employment with any other employer
    required to be aggregated with the Employer under Code Sections 414(b), (c),
    (m) or (o) and the regulations thereunder for purposes of eligibility and
    vesting.  Hours-of-Service shall also be credited for any individual who is
    considered an employee for purposes of this Plan pursuant to Code Section
    414(n) or Code Section 414(o) and the regulations thereunder.

    Solely for purposes of determining whether a one-year break in service has
    occurred for eligibility or vesting purposes, during a Parental Absence an
    Employee shall be credited with the Hours-of-Service which otherwise would
    normally have been credited to the Employee but for such absence, or in any
    case in which such hours cannot be determined, eight Hours-of-Service per
    day of such absence.  The Hours-of-Service credited under this paragraph
    shall be credited in the computation period in which the absence begins if
    the crediting is necessary to prevent a break in service in that period; or
    in all other cases, in the following computation period.

    equal to the aggregate of all his countable Periods of Service.  This period
    of Vesting Service shall be expressed as whole years and fractional parts of
    a year (to two decimal places) on the basis that 365 days equal one year.

    However, Vesting Service is modified as follows:

    Predecessor Employer service included:

          An Employee's service with a Predecessor Employer shall be included as
        service with the Employer.  This service excludes service performed
        while a proprietor or partner.

    Period of Military Duty included:

          A Period of Military Duty shall be included as service with the
        Employer to the extent it has not already been credited.

    Period of Severance included (service spanning rule):

          A Period of Severance shall be deemed to be a Period of Service under
        either of the following conditions:

        (a) the Period of Severance immediately follows a period during which an
            Employee is not absent from work and ends within 12 months; or

                                       15
<PAGE>
 
        (b) the Period of Severance immediately follows a period during which an
            Employee is absent from work for any reason other than quitting,
            being discharged or retiring (such as a leave of absence or layoff)
            and ends within 12 months of the date he was first absent.

    Controlled Group service included:

          An Employee's service with a member firm of a Controlled Group while
        both that firm and the Employer were members of the Controlled Group
        shall be included as service with the Employer.

    YEARLY DATE means January 1, 1991 and the same day of each following year.

    YEARS OF SERVICE means an Employee's Vesting Service disregarding any
    modifications which exclude service.

                                 PARTICIPATION

SECTION 2.01--ACTIVE PARTICIPANT.

    (a) For purposes of Elective Deferral Contributions, an Employee shall first
        become an Active Participant (begin active participation in the Plan) on
        the earliest Monthly Date on or after April 1, 1998, on which he is an
        Eligible Employee. This is his Entry Date.

        For purposes of Employer Contributions other than Elective Deferral
        Contributions, an Employee shall first become an Active Participant
        (begin active participation in the Plan) on the earliest Monthly Date on
        or after April 1, 1998, on which he is an Eligible Employee and has met
        the eligibility requirement set forth below. This date is his Entry
        Date.

        (1) He has completed one year of Eligibility Service before his Entry
            Date.

        Each Employee who was an Active Participant under the Plan on March
        31, 1998, shall continue to be an Active Participant if he is still an
        Eligible Employee on April 1, 1998, and his Entry Date shall not change.

        If a person has been an Eligible Employee who has met all the
        eligibility requirements above, but is not an Eligible Employee on the
        date which would have been his Entry Date, he shall become an Active
        Participant on the date he again becomes an Eligible Employee.  This
        date is his Entry Date.

    (b) An Inactive Participant shall again become an Active Participant (resume
        active participation in the Plan) on the date he again performs an Hour-
        of-Service as an Eligible Employee.  This date is his Reentry Date.

        Upon again becoming an Active Participant, he shall cease to be an
        Inactive Participant.

    (c) A former Participant shall again become an Active Participant (resume
        active participation in the Plan) on the date he again performs an Hour-
        of-Service as an Eligible Employee.  This date is his Reentry Date.

    There shall be no duplication of benefits for a Participant under this Plan
because of more than one period as an Active Participant.

SECTION 2.02--INACTIVE PARTICIPANT.

    An Active Participant shall become an Inactive Participant (stop accruing
benefits under the Plan) on the earlier of the following:

    (a) The date on which he ceases to be an Eligible Employee (on his
        Retirement Date if the date he ceases to be an Eligible Employee occurs
        within one month of his Retirement Date).

    (b) The effective date of complete termination of the Plan.

                                       17
<PAGE>
 
    An Employee or former Employee who was an Inactive Participant under the
Plan on March 31, 1998, shall continue to be an Inactive Participant on April 1,
1998.  Eligibility for any benefits payable to him or on his behalf and the
amount of the benefits shall be determined according to the provisions of the
prior document, unless otherwise stated in this document.

SECTION 2.03--CESSATION OF PARTICIPATION.

    A Participant shall cease to be a Participant on the date he is no longer an
Eligible Employee and his Account is zero.

SECTION 2.04--ADOPTING EMPLOYERS - SINGLE PLAN.

    Each of the employers controlled by or affiliated with the Employer and
listed below is an Adopting Employer.  Each Adopting Employer listed below
participates with the Employer in this Plan.  An Adopting Employer's agreement
to participate in this Plan shall be in writing.

    If the Adopting Employer did not maintain its plan before its date of
adoption specified below, its date of adoption shall be the Entry Date for any
of its employees who have met the requirements in the ACTIVE PARTICIPANT SECTION
of Article II as of that date.  Service with and earnings from an Adopting
Employer shall be included as service with and earnings from the Employer.
Transfer of employment, without interruption, between an Adopting Employer and
another Adopting Employer or the Employer shall not be considered an
interruption of service.

    Contributions made by an Adopting Employer shall be treated as Contributions
made by the Employer.  Forfeitures arising from those Contributions shall be
used for the benefit of all Participants.

    An employer shall not be an Adopting Employer if it ceases to be controlled
by or affiliated with the Employer.  Such an employer may continue a retirement
plan for its employees in the form of a separate document.  This Plan shall be
amended to delete a former Adopting Employer from the list below.

    If an employer ceases to be an Adopting Employer and does not continue a
retirement plan for the benefit of its employees, partial termination may result
and the provisions of Article VII apply.

                                 CONTRIBUTIONS

SECTION 3.01--EMPLOYER CONTRIBUTIONS.

    Employer Contributions for Plan Years which end on or after April 1, 1998,
may be made without regard to current or accumulated net income, earnings, or
profits of the Employer.  Notwithstanding the foregoing, the Plan shall continue
to be designed to qualify as a profit sharing plan for purposes of Code Sections
401(a), 402, 412, and 417.  Such Contributions will be equal to the Employer
Contributions as described below:

    (a) The amount of each Elective Deferral Contribution for a Participant
        shall be equal to any percentage of his Compensation as elected in his
        elective deferral agreement.  An Employee who is eligible to participate
        in the Plan may file an elective deferral agreement with the Employer.
        The elective deferral agreement to start Elective Deferral Contributions
        may be effective on a Participant's Entry Date (Reentry Date, if
        applicable) or any following Monthly Date.  The Participant shall make
        any change or terminate the elective deferral agreement by filing a new
        elective deferral agreement.  A Participant's elective deferral
        agreement making a change may be effective on any date an elective
        deferral agreement to start Elective Deferral Contributions could be
        effective.  A Participant's elective deferral agreement to stop Elective
        Deferral Contributions may be effective on any date.  A Participant may
        not defer more than 20% of his Compensation for the Plan Year.  The
        elective deferral agreement must be in writing and effective before the
        beginning of the pay period in which Elective Deferral Contributions are
        to start, change or stop.

        Elective Deferral Contributions are fully (100%) vested and
        nonforfeitable.

    (b) The amount of each Matching Contribution for a Participant eligible for
        an allocation for the Plan Year shall be equal to a percentage (not more
        than 100%) as determined by the Employer, of the Elective Deferral
        Contributions made for him for Plan Year, disregarding any Elective
        Deferral Contributions in excess of a percentage as determined by the
        Employer, of his Compensation for the Plan Year.

        Matching Contributions are subject to the Vesting Percentage.

    No Participant shall be permitted to have Elective Deferral Contributions,
as defined in the EXCESS AMOUNTS SECTION of Article III, made under this Plan,
or any other qualified plan maintained by the Employer, during any taxable year,
in excess of the dollar limitation contained in Code Section 402(g) in effect at
the beginning of such taxable year.

    The Employer shall pay to the Trustee its Contributions used to determine
the Actual Deferral Percentage, as defined in the EXCESS AMOUNTS SECTION of
Article III, to the Plan for each Plan Year not later than the end of the
twelve-month period immediately following the Plan Year for which they are
deemed to be paid.  Any such Contributions accumulated through payroll
deductions shall be paid within 90 days of the date withheld or the date it is
first reasonably practical for the Employer to do so, if earlier.

    A portion of the Plan assets resulting from Employer Contributions (but not
more than the original amount of those Contributions and reduced proportionately
for losses, if applicable) may be returned if the Employer Contributions are
made because of a mistake of fact or are more than the amount deductible under

                                       19
<PAGE>
 
Code Section 404 (excluding any amount which is not deductible because the Plan
is disqualified).  The amount involved must be returned to the Employer within
one year after the date the Employer Contributions are made by mistake of fact
or the date the deduction is disallowed, whichever applies.  Except as provided
under this paragraph and Article VII, the assets of the Plan shall never be used
for the benefit of the Employer and are held for the exclusive purpose of
providing benefits to Participants and their Beneficiaries and for defraying
reasonable expenses of administering the Plan.

SECTION 3.01A--ROLLOVER CONTRIBUTIONS.

    A Rollover Contribution may be made by or for an Eligible Employee if the
following conditions are met:

    (a) The Contribution is a rollover contribution which the Code permits to be
        transferred to a plan that meets the requirements of Code Section
        401(a).

    (b) If the Contribution is made by the Eligible Employee, it is made within
        sixty days after he receives the distribution.

    (c) The Eligible Employee furnishes evidence satisfactory to the Plan
        Administrator that the proposed transfer is in fact a rollover
        contribution that meets conditions (a) and (b) above.

    The Rollover Contribution may be made by the Eligible Employee or the
Eligible Employee may direct the trustee or named fiduciary of another plan to
transfer the funds which would otherwise be a Rollover Contribution directly to
this Plan.  Such transferred funds shall be called a Rollover Contribution.  The
Contribution shall be made according to procedures set up by the Plan
Administrator.

    If the Eligible Employee is not an Active Participant at the time the
Rollover Contribution is made, he shall be deemed to be a Participant only for
the purposes of investment and distribution of the Rollover Contribution.  He
shall not share in the allocation of Employer Contributions until the time he
meets all the requirements to become an Active Participant.

    Rollover Contributions made by or for an Eligible Employee shall be credited
to his Account.  The part of the Participant's Account resulting from Rollover
Contributions is fully (100%) vested and nonforfeitable at all times.  A
separate accounting record shall be maintained for that part of his Rollover
Contribution which consists of voluntary contributions that were deducted from
the Participant's gross income for Federal income tax purposes.

SECTION 3.02--FORFEITURES.

    The Nonvested Account of a Participant shall be forfeited as of the earlier
of the following:  the date of the Participant's death, if prior to such date he
had ceased to be an Employee; or his Forfeiture Date.  All or a part of a
Participant's Nonvested Account will be forfeited if, after he ceases to be an
Employee, he receives a distribution of his entire Vested Account or a
distribution of his Vested Account derived from Employer Contributions which
were not 100% vested when made according to the provisions of the VESTED
BENEFITS SECTION of Article V or the SMALL AMOUNTS SECTION of Article IX.  If a
Participant's Vested Account is zero on the date he ceases to be an Employee, he
shall be deemed to have received a distribution of his entire Vested Account on
such date.  The forfeiture will occur as of the date he receives the
distribution or on the date such provision became effective, if later. If he
receives a distribution of his entire Vested Account, his entire Nonvested
Account will be forfeited.  If he receives a distribution of his Vested Account
from Employer Contributions which were not 100% vested when made, but less than
his entire Vested Account, the amount 

                                       20
<PAGE>
 
to be forfeited will be determined by multiplying his Nonvested Account by a
fraction. The numerator of the fraction is the amount of the distribution
derived from Employer Contributions which were not 100% vested when made and the
denominator of the fraction is his entire Vested Account derived from such
Employer Contributions on the date of distribution.

    A Forfeiture shall also occur as described in the EXCESS AMOUNTS SECTION of
Article III.

    Forfeitures may first be applied to pay administrative expenses under the
Plan which would otherwise be paid by the Employer.

    Forfeitures not used to pay administrative expenses shall be applied to
reduce the earliest Employer Contributions made after the Forfeitures are
determined.  Forfeitures shall be determined at least once during each taxable
year of the Employer.  Upon their application, such Forfeitures shall be deemed
to be Employer Contributions.

    Forfeitures of Matching Contributions which relate to excess amounts shall
be applied as provided in the EXCESS AMOUNTS SECTION of Article III.

    If a Participant again becomes an Eligible Employee after receiving a
distribution which caused his Nonvested Account to be forfeited, he shall have
the right to repay to the Plan the entire amount of the distribution he received
(excluding any amount of such distribution resulting from Contributions which
were 100% vested when made).  The repayment must be made before the earlier of
the date five years after the date he again becomes an Eligible Employee or the
end of the first period of five consecutive one-year Periods of Severance which
begin after the date of the distribution.

    If the Participant makes the repayment provided above, the Plan
Administrator shall restore to his Account an amount equal to his Nonvested
Account which was forfeited on the date of distribution, unadjusted for any
investment gains or losses.  If the amount of the repayment is zero dollars
because the Participant was deemed to have received a distribution or the plan
did not have repayment provisions in effect on the date the distribution was
made and he again performs an Hour-of-Service as an Eligible Employee within the
repayment period, the Plan Administrator shall restore the Participant's Account
as if he had made a required repayment on the date he performed such Hour-of-
Service.  Restoration of the Participant's Account shall include restoration of
all Code Section 411(d)(6) protected benefits with respect to that restored
Account, according to applicable Treasury regulations.  Provided, however, the
Plan Administrator shall not restore the Nonvested Account if a Forfeiture Date
has occurred after the date of the distribution and on or before the date of
repayment and that Forfeiture Date would result in a complete forfeiture of the
amount the Plan Administrator would otherwise restore.

    The Plan Administrator shall restore the Participant's Account by the close
of the Plan Year following the Plan Year in which repayment is made.
Permissible sources for restoration are Forfeitures or Employer Contributions.
The Employer shall contribute, without regard to any requirement or condition of
the EMPLOYER CONTRIBUTIONS SECTION of Article III, such additional amount needed
to make the required restoration.  The repaid and restored amounts are not
included in the Participant's Annual Addition, as defined in the CONTRIBUTION
LIMITATION SECTION of Article III.

                                       21
<PAGE>
 
SECTION 3.03--ALLOCATION.

    The following Contributions for the Plan Year shall be allocated among all
eligible persons:

    Matching Contributions

    The eligible persons are all Participants and former Participants who (i)
are Active Participants on the last day of the Plan Year or (ii) were Active
Participants at any time in the Plan Year and have died, retired or become
Totally and Permanently Disabled.  The amount allocated to such a person shall
be determined below and under Article X.

    The following Contributions for each Plan Year shall be allocated to each
Participant for whom such Contributions were made under the EMPLOYER
CONTRIBUTIONS SECTION of Article III:

    Elective Deferral Contributions

These Contributions shall be allocated when made and credited to the
Participant's Account.

    In determining the amount of Employer Contributions to be allocated to a
Participant who is a Leased Employee, contributions and benefits provided by the
leasing organization which are attributable to services such Leased Employee
performs for the Employer shall be treated as provided by the Employer and there
shall be no duplication of those contributions or benefits under this Plan.

SECTION 3.04--CONTRIBUTION LIMITATION.

    (a) For the purpose of determining the contribution limitation set forth in
        this section, the following terms are defined:

        Aggregate Annual Addition means, for a Participant with respect to any
        Limitation Year, the sum of his Annual Additions under all defined
        contribution plans of the Employer, as defined in this section, for such
        Limitation Year.  The nondeductible participant contributions which the
        Participant makes to a defined benefit plan shall be treated as Annual
        Additions to a defined contribution plan.  The Contributions the
        Employer, as defined in this section, made for the Participant for a
        Plan Year beginning on or after March 31, 1984, to an individual medical
        benefit account, as defined in Code Section 415(l)(2), under a pension
        or annuity plan of the Employer, as defined in this section, shall be
        treated as Annual Additions to a defined contribution plan.  Also,
        amounts derived from contributions paid or accrued after December 31,
        1985, in Fiscal 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, as defined in this section, are treated as Annual Additions to
        a defined contribution plan.  The 25% of Compensation limit under
        Maximum Permissible Amount does not apply to Annual Additions resulting
        from contributions made to an individual medical account, as defined in
        Code Section 415(l)(2), or to Annual Additions resulting from
        contributions for medical benefits, within the meaning of Code Section
        419A, after separation from service.

        Annual Addition means the amount added to a Participant's account for
        any Limitation Year which may not exceed the Maximum Permissible Amount.
        The Annual Addition under any plan for a Participant with respect to any
        Limitation Year, shall be equal to the sum of (1) and (2) below:

                                       22
<PAGE>
 
        (1) Employer contributions and forfeitures credited to his account for
            the Limitation Year.

        (2) Participant contributions made by him for the Limitation Year.

        Before the first Limitation Year beginning after December 31, 1986,
        the amount under (2) above is the lesser of (i) 1/2 of his nondeductible
        participant contributions made for the Limitation Year, or (ii) the
        amount, if any, of his nondeductible participant contributions made for
        the Limitation Year which is in excess of six percent of his
        Compensation, as defined in this section, for such Limitation Year.

        Compensation means all wages for Federal income tax withholding
        purposes, as defined under Code Section 3401(a) (for purposes of income
        tax withholding at the source), disregarding any rules limiting the
        remuneration included as wages based on the nature or location of the
        employment or the services performed.  Compensation also includes all
        other payments to an Employee in the course of the Employer's trade or
        business, for which the Employer must furnish the Employee a written
        statement under Code Sections 6041(d) and 6051(a)(3).  The "Wages, Tips
        and Other Compensation" box on Form W-2 satisfies this definition.

        For purposes of applying the limitations of this section, Compensation
        for a Limitation Year is the Compensation actually paid or made
        available during such Limitation Year.

        Defined Benefit Plan Fraction means, with respect to a Limitation Year
        for a Participant who is or has been a participant in a defined benefit
        plan ever maintained by the Employer, as defined in this section, the
        quotient, expressed as a decimal, of

        (1) the Participant's Projected Annual Benefit under all such plans as
            of the close of such Limitation Year, divided by

        (2) on and after the TEFRA Compliance Date, the lesser of (i) or (ii)
            below:

            (i) 1.25 multiplied by the maximum dollar limitation which applies
                to defined benefit plans determined for the Limitation Year
                under Code Sections 415(b) or (d) or

            (ii) 1.4 multiplied by the Participant's highest average
                compensation as defined in the defined benefit plan(s),

            including any adjustments under Code Section 415(b).

            Before the TEFRA Compliance Date, this denominator is the
            Participant's Projected Annual Benefit as of the close of the
            Limitation Year if the plan(s) provided the maximum benefit
            allowable.

        The Defined Benefit Plan Fraction shall be modified as follows:

        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, as defined in this
        section, 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
        close of the last Limitation Year beginning before January 1, 1987,

                                       23
<PAGE>
 
        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 requirements of
        Code Section 415 for all Limitation Years beginning before January 1,
        1987.

          Defined Contribution Plan Fraction means, for a Participant with
        respect to a Limitation Year, the quotient, expressed as a decimal, of

        (1) the Participant's Aggregate Annual Additions for such Limitation
            Year and all prior Limitation Years, under all defined contribution
            plans (including the Aggregate Annual Additions attributable to
            nondeductible accounts under defined benefit plans and attributable
            to all welfare benefit funds, as defined in Code Section 419(e) and
            attributable to individual medical accounts, as defined in Code
            Section 415(l)(2)) ever maintained by the Employer, as defined in
            this section, divided by

        (2) on and after the TEFRA Compliance Date, the sum of the amount
            determined for the Limitation Year under (i) or (ii) below,
            whichever is less, and the amounts determined in the same manner for
            all prior Limitation Years during which he has been an Employee or
            an employee of a predecessor employer:

            (i)  1.25 multiplied by the maximum permissible dollar amount for
                 each such Limitation Year, or

            (ii) 1.4 multiplied by the maximum permissible percentage of the
                 Participant's Compensation, as defined in this section, for
                 each such Limitation Year.

            Before the TEFRA Compliance Date, this denominator is the sum of
            the maximum allowable amount of Annual Addition to his account(s)
            under all the plan(s) of the Employer, as defined in this section,
            for each such Limitation Year.

        The Defined Contribution Plan Fraction shall be modified as follows:

        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 contribution plans maintained by the Employer, as defined in
        this section, which were in existence on May 6, 1986, the numerator of
        this fraction shall be adjusted if the sum of the Defined Contribution
        Plan Fraction and Defined Benefit Plan Fraction would otherwise exceed
        1.0 under the terms of this Plan.  Under the adjustment, the dollar
        amount determined below shall be permanently subtracted from the
        numerator of this fraction.  The dollar amount is equal to the excess of
        the sum of the two fractions, before adjustment, over 1.0 multiplied by
        the denominator of his Defined Contribution Plan Fraction.  The
        adjustment is calculated using his Defined Contribution Plan Fraction
        and Defined Benefit Plan Fraction 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 limitations applicable
        to the first Limitation Year beginning on or after January 1, 1987.

        The Annual Addition for any Limitation Year beginning before January
        1, 1987, shall not be recomputed to treat all employee contributions as
        Annual Additions.

        For a plan that was in existence on July 1, 1982, for purposes of
        determining the Defined Contribution Plan Fraction for any Limitation
        Year ending after December 31, 1982, the Plan Administrator may elect,
        in accordance with the provisions of Code Section 415, that the
        denominator for each Participant for all Limitation Years ending before
        January 1, 1983, will be equal to

        (1) the Defined Contribution Plan Fraction denominator which would apply
            for the last Limitation Year ending in 1982 if an election under
            this paragraph were not made, multiplied by.

        (2) a fraction, equal to (i) over (ii) below:

             (i) the lesser of (A) $51,875, or (B) 1.4, multiplied by 25% of the
                 Participant's Compensation, as defined in this section, for the
                 Limitation Year ending in 1981;

            (ii) the lesser of (A) $41,500, or (B) 25% of the Participant's
                 Compensation, as defined in this section, for the Limitation
                 Year ending in 1981.

        The election described above is applicable only if the plan
        administrators under all defined contribution plans of the Employer, as
        defined in this section, also elect to use the modified fraction.

        Employer means any employer that adopts this Plan and all Controlled
        Group members and any other entity required to be aggregated with the
        employer pursuant to regulations under Code Section 414(o).

        Limitation Year means the 12-consecutive month period within which it
        is determined whether or not the limitations of Code Section 415 are
        exceeded.  Limitation Year means each 12-consecutive month period ending
        on the last day of each Plan Year, including corresponding 12-
        consecutive month periods before January 1, 1991.  If the Limitation
        Year is other than the calendar year, execution of this Plan (or any
        amendment to this Plan changing the Limitation Year) constitutes the
        Employer's adoption of a written resolution electing the Limitation
        Year.  If the Limitation Year is changed, the new Limitation Year shall
        begin within the current Limitation Year, creating a short Limitation
        Year.

        Maximum Permissible Amount means, for a Participant with respect to
        any Limitation Year, the lesser of (1) or (2) below:

        (1) The greater of $30,000 or one-fourth of the maximum dollar
            limitation which applies to defined benefit plans set forth in Code
            Section 415(b)(1)(A) as in effect for the Limitation Year.  (Before
            the TEFRA Compliance Date, $25,000 multiplied by the cost of living
            adjustment factor permitted by Federal regulations.)

        (2) 25% of his Compensation, as defined in this section, for such
            Limitation Year.

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

                                       25
<PAGE>
 
        If there is a short Limitation Year because of a change in Limitation
        Year, the Maximum Permissible Amount will not exceed the maximum dollar
        limitation which would otherwise apply multiplied by the following
        fraction:

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

        Projected Annual Benefit means a Participant's expected annual benefit
        under all defined benefit plan(s) ever maintained by the Employer, as
        defined in this section.  The Projected Annual Benefit shall be
        determined assuming that the Participant will continue employment until
        the later of current age or normal retirement age under such plan(s),
        and that the Participant's compensation for the current Limitation Year
        and all other relevant factors used to determine benefits under such
        plan(s) will remain constant for all future Limitation Years.  Such
        expected annual benefit shall be adjusted to the actuarial equivalent of
        a straight life annuity if expressed in a form other than a straight
        life or qualified joint and survivor annuity.

    (b) The Annual Addition under this Plan for a Participant during a
        Limitation Year shall not be more than the Maximum Permissible Amount.

    (c) Contributions which would otherwise be credited to the Participant's
        Account shall be limited or reallocated to the extent necessary to meet
        the restrictions of subparagraph (b) above for any Limitation Year in
        the following order.  Elective Deferral Contributions that are not the
        basis for Matching Contributions shall be limited.  Matching
        Contributions shall be limited to the extent necessary to limit the
        Participant's Annual Addition under this Plan to his maximum amount.  If
        Matching Contributions are limited because of this limit, Elective
        Deferral Contributions that are the basis for Matching Contributions
        shall be reduced in proportion.

        If, due to (i) an error in estimating a Participant's Compensation as
        defined in this section, (ii) because the amount of the Forfeitures to
        be used to offset Employer Contributions is more than the amount of the
        Employer Contributions due for the remaining Participants, (iii) as a
        result of 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 individual under the limits of Code Section
        415, or (iv) other limited facts and circumstances, a Participant's
        Annual Addition is greater than the amount permitted in (b) above, such
        excess amount shall be applied as follows.  Elective Deferral
        Contributions which are not the basis for Matching Contributions will be
        returned to the Participant.  If an excess still exists, Elective
        Deferral Contributions that are the basis for Matching Contributions
        will be returned to the Participant.  Matching Contributions based on
        Elective Deferral Contributions which are returned shall be forfeited.
        If after the return of Elective Deferral Contributions, an excess amount
        still exists, and the Participant is an Active Participant as of the end
        of the Limitation Year, the excess amount shall be used to offset
        Employer Contributions for him in the next Limitation Year.  If after
        the return of Elective Deferral Contributions, an excess amount still
        exists, and the Participant is not an Active Participant as of the end
        of the Limitation Year, the excess amount will be held in a suspense
        account which will be used to offset Employer Contributions for all
        Participants in the next Limitation Year.  No Employer Contributions
        that would be included in the next Limitation Year's Annual Addition may
        be made before the total suspense account has been used.

    (d) A Participant's Aggregate Annual Addition for a Limitation Year shall
        not exceed the Maximum Permissible Amount.

                                       26
<PAGE>
 
        If, for the Limitation Year, the Participant has an Annual Addition
        under more than one defined contribution plan or a welfare benefit fund,
        as defined in Code Section 419(e), or an individual medical account, as
        defined in Code Section 415(l)(2), maintained by the Employer, as
        defined in this section, and such plans and welfare benefit funds and
        individual medical accounts do not otherwise limit the Aggregate Annual
        Addition to the Maximum Permissible Amount, any reduction necessary
        shall be made first to the profit sharing plans, then to all other such
        plans and welfare benefit funds and individual medical accounts and, if
        necessary, by reducing first those that were most recently allocated.
        Welfare benefit funds and individual medical accounts shall be deemed to
        be allocated first.  However, elective deferral contributions shall be
        the last contributions reduced before the welfare benefit fund or
        individual medical account is reduced.

        If some of the Employer's defined contribution plans were not in
        existence on July 1, 1982, and some were in existence on that date, the
        Maximum Permissible Amount which is based on a dollar amount may differ
        for a Limitation Year.  The Aggregate Annual Addition for the Limitation
        Year in which the dollar limit differs shall not exceed the lesser of
        (1) 25% of Compensation as defined in this section, (2) $45,475, or (3)
        the greater of $30,000 or the sum of the Annual Additions for such
        Limitation Year under all the plan(s) to which the $45,475 amount
        applies.

    (e) If a Participant is or has been a participant in both defined benefit
        and defined contribution plans (including a welfare benefit fund or
        individual medical account) ever maintained by the Employer, as defined
        in this section, the sum of the Defined Benefit Plan Fraction and the
        Defined Contribution Plan Fraction for any Limitation Year shall not
        exceed 1.0 (1.4 before the TEFRA Compliance Date).

        After all other limitations set out in the plans and funds have been
        applied, the following limitations shall apply so that the sum of the
        Participant's Defined Benefit Plan Fraction and Defined Contribution
        Plan Fraction shall not exceed 1.0 (1.4 before the TEFRA Compliance
        Date).  The Projected Annual Benefit shall be limited first.  If the
        Participant's annual benefit(s) equal his Projected Annual Benefit, as
        limited, then Annual Additions to the defined contribution plan(s) shall
        be limited to the extent needed to reduce the sum to 1.0 (1.4).  First,
        the voluntary contributions the Participant may make for the Limitation
        Year shall be limited.  Next, in the case of a profit sharing plan, any
        forfeitures allocated to the Participant shall be reallocated to
        remaining participants to the extent necessary to reduce the decimal to
        1.0 (1.4).  Last, to the extent necessary, employer contributions for
        the Limitation Year shall be reallocated or limited, and any required
        and optional employee contributions to which such employer contributions
        were geared shall be reduced in proportion.

        If, for the Limitation Year, the Participant has an Annual Addition
        under more than one defined contribution plan or welfare benefit fund or
        individual medical account maintained by the Employer, as defined in
        this section, any reduction above shall be made first to the profit
        sharing plans, then to all other such plans and welfare benefit plans
        and individual medical accounts and, if necessary, by reducing first
        those that were most recently allocated.  However, elective deferral
        contributions shall be the last contributions reduced before the welfare
        benefit fund or individual medical account is reduced.  The annual
        addition to the welfare benefit fund and individual medical account
        shall be limited last.

SECTION 3.05--EXCESS AMOUNTS.

    (a) For the purposes of this section, the following terms are defined:

                                       27
<PAGE>
 
        Actual Deferral Percentage means the ratio (expressed as a percentage)
        of Elective Deferral Contributions under this Plan on behalf of the
        Eligible Participant for the Plan Year to the Eligible Participant's
        Compensation for the Plan Year.  The Elective Deferral Contributions
        used to determine the Actual Deferral Percentage shall include Excess
        Elective Deferrals (other than Excess Elective Deferrals of Nonhighly
        Compensated Employees that arise solely from Elective Deferral
        Contributions made under this Plan or any other plans of the Employer or
        a Controlled Group member), but shall exclude Elective Deferral
        Contributions that are used in computing the Contribution Percentage
        (provided the Average Actual Deferral Percentage test is satisfied both
        with and without exclusion of these Elective Deferral Contributions).
        Under such rules as the Secretary of the Treasury shall prescribe in
        Code Section 401(k)(3)(D), the Employer may elect to include Qualified
        Nonelective Contributions and Qualified Matching Contributions under
        this Plan in computing the Actual Deferral Percentage.  For an Eligible
        Participant for whom such Contributions on his behalf for the Plan Year
        are zero, the percentage is zero.

        Aggregate Limit means the greater of (1) or (2) below:

        (1) The sum of

            (i)  125 percent of the greater of the Average Actual Deferral
                 Percentage of the Nonhighly Compensated Employees for the Plan
                 Year or the Average Contribution Percentage of Nonhighly
                 Compensated Employees under the Plan subject to Code Section
                 401(m) for the Plan Year beginning with or within the Plan Year
                 of the cash or deferred arrangement and

            (ii) the lesser of 200% or two plus the lesser of such Average
                 Actual Deferral Percentage or Average Contribution Percentage.

        (2) The sum of

            (i)  125 percent of the lesser of the Average Actual Deferral
                 Percentage of the Nonhighly Compensated Employees for the Plan
                 Year or the Average Contribution Percentage of Nonhighly
                 Compensated Employees under the Plan subject to Code Section
                 401(m) for the Plan Year beginning with or within the Plan Year
                 of the cash or deferred arrangement and

            (ii) the lesser of 200% or two plus the greater of such Average
                 Actual Deferral Percentage or Average Contribution Percentage.

        Average Actual Deferral Percentage means the average (expressed as a
        percentage) of the Actual Deferral Percentages of the Eligible
        Participants in a group.

        Average Contribution Percentage means the average (expressed as a
        percentage) of the Contribution Percentages of the Eligible Participants
        in a group.

        Contribution Percentage means the ratio (expressed as a percentage) of
        the Eligible Participant's Contribution Percentage Amounts to the
        Eligible Participant's Compensation for the Plan Year.  For an Eligible
        Participant for whom such Contribution Percentage Amounts for the Plan
        Year are zero, the percentage is zero.

                                       28
<PAGE>
 
        Contribution Percentage Amounts means the sum of the Participant
        Contributions and Matching Contributions (that are not Qualified
        Matching Contributions) under this Plan on behalf of the Eligible
        Participant for the Plan Year.  Such Contribution Percentage Amounts
        shall not include Matching Contributions that are forfeited either to
        correct Excess Aggregate Contributions or because the Contributions to
        which they relate are Excess Elective Deferrals, Excess Contributions or
        Excess Aggregate Contributions.  Under such rules as the Secretary of
        the Treasury shall prescribe in Code Section 401(k)(3)(D), the Employer
        may elect to include Qualified Nonelective Contributions and Qualified
        Matching Contributions under this Plan which were not used in computing
        the Actual Deferral Percentage in computing the Contribution Percentage.
        The Employer may also elect to use Elective Deferral Contributions in
        computing the Contribution Percentage so long as the Average Actual
        Deferral Percentage test is met before the Elective Deferral
        Contributions are used in the Average Contribution Percentage test and
        continues to be met following the exclusion of those Elective Deferral
        Contributions that are used to meet the Average Contribution Percentage
        test.

        Elective Deferral Contributions means employer contributions made on
        behalf of a participant pursuant to an election to defer under any
        qualified cash or deferred arrangement as described in Code Section
        401(k), any simplified employee pension cash or deferred arrangement as
        described in Code Section 402(h)(1)(B), any eligible deferred
        compensation plan under Code Section 457, any plan as described under
        Code Section 501(c)(18), and any employer contributions made on behalf
        of a participant for the purchase of an annuity contract under Code
        Section 403(b) pursuant to a salary reduction agreement.  Elective
        Deferral Contributions shall not include any deferrals properly
        distributed as excess Annual Additions.

        Eligible Participant means, for purposes of the Actual Deferral
        Percentage, any Employee who is eligible to make an Elective Deferral
        Contribution, and shall include the following:  any Employee who would
        be a plan participant if he chose to make required contributions; any
        Employee who can make Elective Deferral Contributions but who has
        changed the amount of his Elective Deferral Contribution to 0%, or whose
        eligibility to make an Elective Deferral Contribution is suspended
        because of a loan, distribution or hardship withdrawal; and, any
        Employee who is not able to make an Elective Deferral Contribution
        because of Code Section 415(c)(1) - Annual Additions limits.  The Actual
        Deferral Percentage for any such included Employee is zero.

        Eligible Participant means, for purposes of the Average Contribution
        Percentage, any Employee who is eligible to make a Participant
        Contribution or to receive a Matching Contribution, and shall include
        the following:  any Employee who would be a plan participant if he chose
        to make required contributions; any Employee who can make a Participant
        Contribution or receive a matching contribution but who has made an
        election not to participate in the Plan; and any Employee who is not
        able to make a Participant Contribution or receive a matching
        contribution because of Code Section 415(c)(1) or 415(e) limits.  The
        Average Contribution Percentage for any such included Employee is zero.

        Excess Aggregate Contributions means, with respect to any Plan Year, the
        excess of:

        (1) The aggregate Contributions taken into account in computing the
            numerator of the Contribution Percentage actually made on behalf of
            Highly Compensated Employees for such Plan Year, over

        (2) The maximum amount of such Contributions permitted by the Average
            Contribution Percentage test (determined by reducing Contributions
            made on behalf of Highly 

                                       29
<PAGE>
 
            Compensated Employees in order of their Contribution Percentages
            beginning with the highest of such percentages).

        Such determination shall be made after first determining Excess
        Elective Deferrals and then determining Excess Contributions.

        Excess Contributions means, with respect to any Plan Year, the excess
        of:

        (1) The aggregate amount of Contributions actually taken into account in
            computing the Actual Deferral Percentage of Highly Compensated
            Employees for such Plan Year, over

        (2) The maximum amount of such Contributions permitted by the Actual
            Deferral Percentage test (determined by reducing Contributions made
            on behalf of Highly Compensated Employees in order of the Actual
            Deferral Percentages, beginning with the highest of such
            percentages).

        A Participant's Excess Contributions for a Plan Year will be reduced
        by the amount of Excess Elective Deferrals, if any, previously
        distributed to the Participant for the taxable year ending in that Plan
        Year.

        Excess Elective Deferrals means those Elective Deferral Contributions
        that are includible in a Participant's gross income under Code Section
        402(g) to the extent such Participant's Elective Deferral Contributions
        for a taxable year exceed the dollar limitation under such Code section.
        Excess Elective Deferrals shall be treated as Annual Additions, as
        defined in the CONTRIBUTION LIMITATION SECTION of Article III, under the
        Plan, unless such amounts are distributed no later than the first April
        15 following the close of the Participant's taxable year.

        Family Member means an Employee, or former employee; the spouse of the
        Employee or former employee, and the lineal ascendants or descendants
        and the spouses of such lineal ascendants or descendants of any such
        Employee or former employee.  In determining if an individual is a
        family member as to an Employee or former employee, legal adoptions are
        taken into account.

        Matching Contributions means employer contributions made to this or
        any other defined contribution plan, or to a contract described in Code
        Section 403(b), on behalf of a participant on account of a Participant
        Contribution made by such participant, or on account of a participant's
        Elective Deferral Contributions, under a plan maintained by the
        employer.

        Participant Contributions means contributions made to any plan by or
        on behalf of a participant that are included in the participant's gross
        income in the year in which made and that are maintained under a
        separate account to which earnings and losses are allocated.

        Qualified Matching Contributions means Matching Contributions which
        are subject to the distribution and nonforfeitability requirements under
        Code Section 401(k) when made.

        Qualified Nonelective Contributions means any employer contributions
        (other than Matching Contributions) which an employee may not elect to
        have paid to him in cash instead of being contributed to the plan and
        which are subject to the distribution and nonforfeitability requirements
        under Code Section 401(k) when made.

                                       30
<PAGE>
 
    (b) A Participant may assign to this Plan any Excess Elective Deferrals made
        during a taxable year by notifying the Plan Administrator in writing on
        or before the first following March 1 of the amount of the Excess
        Elective Deferrals to be assigned to the Plan.  A Participant is deemed
        to notify the Plan Administrator of any Excess Elective Deferrals that
        arise by taking into account only those Elective Deferral Contributions
        made to this Plan and any other plans of the Employer or a Controlled
        Group member and reducing such Excess Elective Deferrals by the amount
        of Excess Contributions, if any, previously distributed for the Plan
        Year beginning in that taxable year.  The Participant's claim for Excess
        Elective Deferrals shall be accompanied by the Participant's written
        statement that if such amounts are not distributed, such Excess Elective
        Deferrals, when added to amounts deferred under other plans or
        arrangements described in Code Sections 401(k), 408(k) or 403(b), will
        exceed the limit imposed on the Participant by Code Section 402(g) for
        the year in which the deferral occurred.  The Excess Elective Deferrals
        assigned to this Plan can not exceed the Elective Deferral Contributions
        allocated under this Plan for such taxable year.

        Notwithstanding any other provisions of the Plan, Elective Deferral
        Contributions in an amount equal to the Excess Elective Deferrals
        assigned to this Plan, plus any income and minus any loss allocable
        thereto, shall be distributed no later than April 15 to any Participant
        to whose Account Excess Elective Deferrals were assigned for the
        preceding year and who claims Excess Elective Deferrals for such taxable
        year.

        The income or loss allocable to such Excess Elective Deferrals shall
        be equal to the income or loss allocable to the Participant's Elective
        Deferral Contributions for the taxable year in which the excess occurred
        multiplied by a fraction.  The numerator of the fraction is the Excess
        Elective Deferrals.  The denominator of the fraction is the closing
        balance without regard to any income or loss occurring during such
        taxable year (as of the end of such taxable year) of the Participant's
        Account resulting from Elective Deferral Contributions.

        Any Matching Contributions which were based on the Elective Deferral
        Contributions which are distributed as Excess Elective Deferrals, plus
        any income and minus any loss allocable thereto, shall be forfeited.
        These Forfeitures shall be used to offset the earliest Employer
        Contribution due after the Forfeiture arises.

    (c) As of the end of each Plan Year after Excess Elective Deferrals have
        been determined, one of the following tests must be met:

        (1) The Average Actual Deferral Percentage for Eligible Participants who
            are Highly Compensated Employees for the Plan Year is not more than
            the Average Actual Deferral Percentage for Eligible Participants who
            are Nonhighly Compensated Employees for the Plan Year multiplied by
            1.25.

        (2) The Average Actual Deferral Percentage for Eligible Participants who
            are Highly Compensated Employees for the Plan Year is not more than
            the Average Actual Deferral Percentage for Eligible Participants who
            are Nonhighly Compensated Employees for the Plan Year multiplied by
            2 and the difference between the Average Actual Deferral Percentages
            is not more than 2.

        The Actual Deferral Percentage for any Eligible Participant who is a
        Highly Compensated Employee for the Plan Year and who is eligible to
        have Elective Deferral Contributions (and Qualified Nonelective
        Contributions or Qualified Matching Contributions, or both, if used in
        computing the 

                                       31
<PAGE>
 
        Actual Deferral Percentage) allocated to his account under two or more
        plans or arrangements described in Code Section 401(k) that are
        maintained by the Employer or a Controlled Group member shall be
        determined as if all such Elective Deferral Contributions (and, if
        applicable, such Qualified Nonelective Contributions or Qualified
        Matching Contributions, or both) were made under a single arrangement.
        If a Highly Compensated Employee participates in two or more cash or
        deferred arrangements that have different Plan Years, all cash or
        deferred arrangements ending with or within the same calendar year shall
        be treated as a single arrangement. Notwithstanding the foregoing,
        certain plans shall be treated as separate if mandatorily disaggregated
        under the regulations under Code Section 401(k) or permissibly
        disaggregated as provided.

        In the event that this Plan satisfies the requirements of Code
        Sections 401(k), 401(a)(4), or 410(b) only if aggregated with one or
        more other plans, or if one or more other plans satisfy the requirements
        of such Code sections only if aggregated with this Plan, then this
        section shall be applied by determining the Actual Deferral Percentage
        of employees as if all such plans were a single plan.  Plans may be
        aggregated in order to satisfy Code Section 401(k) only if they have the
        same Plan Year.

        For purposes of determining the Actual Deferral Percentage of an
        Eligible Participant who is a five-percent owner or one of the ten most
        highly-paid Highly Compensated Employees, the Elective Deferral
        Contributions (and Qualified Nonelective Contributions or Qualified
        Matching Contributions, or both, if used in computing the Actual
        Deferral Percentage) and Compensation of such Eligible Participant
        include the Elective Deferral Contributions (and, if applicable,
        Qualified Nonelective Contributions or Qualified Matching Contributions,
        or both) and Compensation for the Plan Year of Family Members.  Family
        Members, with respect to such Highly Compensated Employees, shall be
        disregarded as separate employees in determining the Actual Deferral
        Percentage both for Participants who are Nonhighly Compensated Employees
        and for Participants who are Highly Compensated Employees.

        For purposes of determining the Actual Deferral Percentage, Elective
        Deferral Contributions, Qualified Nonelective Contributions and
        Qualified Matching Contributions must be made before the last day of the
        12-month period immediately following the Plan Year to which
        contributions relate.

        The Employer shall maintain records sufficient to demonstrate
        satisfaction of the Average Actual Deferral Percentage test and the
        amount of Qualified Nonelective Contributions or Qualified Matching
        Contributions, or both, used in such test.

        The determination and treatment of the Contributions used in computing
        the Actual Deferral Percentage shall satisfy such other requirements as
        may be prescribed by the Secretary of the Treasury.

        If the Plan Administrator should determine during the Plan Year that
        neither of the above tests is being met, the Plan Administrator may
        adjust the amount of future Elective Deferral Contributions of the
        Highly Compensated Employees.

        Notwithstanding any other provisions of this Plan, Excess
        Contributions, plus any income and minus any loss allocable thereto,
        shall be distributed no later than the last day of each Plan Year to
        Participants to whose Accounts such Excess Contributions were allocated
        for the preceding Plan Year.  If such excess amounts are distributed
        more than 2 1/2 months after the last day of the Plan Year in which such
        excess amounts arose, a ten (10) percent excise tax will be imposed on

                                       32
<PAGE>
 
        the employer maintaining the plan with respect to such amounts.  Such
        distributions shall be made beginning with the Highly Compensated
        Employee(s) who has the greatest Actual Deferral Percentage, reducing
        his Actual Deferral Percentage to the next highest Actual Deferral
        Percentage level.  Then, if necessary, reducing the Actual Deferral
        Percentage of the Highly Compensated Employees at the next highest
        level, and continuing in this manner until the average Actual Deferral
        Percentage of the Highly Compensated Group satisfies the Actual Deferral
        Percentage test.  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 Deferral Contributions (and
        amounts treated as Elective Deferral Contributions) of each Family
        Member that is combined to determine the combined Actual Deferral
        Percentage.

        Excess Contributions shall be treated as Annual Additions, as defined
        in the CONTRIBUTION LIMITATION SECTION of Article III, under the Plan.

        The Excess Contributions shall be adjusted for income or loss.  The
        income or loss allocable to such Excess Contributions shall be equal to
        the income or loss allocable to the Participant's Elective Deferral
        Contributions (and, if applicable, Qualified Nonelective Contributions
        or Qualified Matching Contributions, or both) for the Plan Year in which
        the excess occurred multiplied by a fraction.  The numerator of the
        fraction is the Excess Contributions.  The denominator of the fraction
        is the closing balance without regard to any income or loss occurring
        during such Plan Year (as of the end of such Plan Year) of the
        Participant's Account resulting from Elective Deferral Contributions
        (and Qualified Nonelective Contributions or Qualified Matching
        Contributions, or both, if used in computing the Actual Deferral
        Percentage).

        Excess Contributions shall be distributed from the Participant's
        Account resulting first from Elective Deferral Contributions not the
        basis for Matching Contributions, then if necessary, from Elective
        Deferral Contributions which are the basis for Matching Contributions.
        If such Excess Contributions exceed the balance in the Participant's
        Account resulting from Elective Deferral Contributions, the balance
        shall be distributed from the Participant's Account resulting from
        Qualified Matching Contributions (if applicable) and Qualified
        Nonelective Contributions, respectively.

        Any Matching Contributions which were based on the Elective Deferral
        Contributions which are distributed as Excess Contributions, plus any
        income and minus any loss allocable thereto, shall be forfeited.  These
        Forfeitures shall be used to offset the earliest Employer Contribution
        due after the Forfeiture arises.

    (d) As of the end of each Plan Year, one of the following tests must be met:

        (1) The Average Contribution Percentage for Eligible Participants who
            are Highly Compensated Employees for the Plan Year is not more than
            the Average Contribution Percentage for Eligible Participants who
            are Nonhighly Compensated Employees for the Plan Year multiplied by
            1.25.

        (2) The Average Contribution Percentage for Eligible Participants who
            are Highly Compensated Employees for the Plan Year is not more than
            the Average Contribution Percentage for Eligible Participants who
            are Nonhighly Compensated Employees for the Plan Year multiplied by
            2 and the difference between the Average Contribution Percentages is
            not more than 2.

                                       33
<PAGE>
 
 
        If one or more Highly Compensated Employees participate in both a cash
        or deferred arrangement and a plan subject to the Average Contribution
        Percentage test maintained by the Employer or a Controlled Group member
        and the sum of the Average Actual Deferral Percentage and Average
        Contribution Percentage of those Highly Compensated Employees subject to
        either or both tests exceeds the Aggregate Limit, then the Contribution
        Percentage of those Highly Compensated Employees who also participate in
        a cash or deferred arrangement will be reduced (beginning with such
        Highly Compensated Employees whose Contribution Percentage is the
        highest) so that the limit is not exceeded.  The amount by which each
        Highly Compensated Employee's Contribution Percentage is reduced shall
        be treated as an Excess Aggregate Contribution.  The Average Actual
        Deferral Percentage and Average Contribution Percentage of the Highly
        Compensated Employees are determined after any corrections required to
        meet the Average Actual Deferral Percentage and Average Contribution
        Percentage tests.  Multiple use does not occur if either the Average
        Actual Deferral Percentage or Average Contribution Percentage of the
        Highly Compensated Employees does not exceed 1.25 multiplied by the
        Average Actual Deferral Percentage and Average Contribution Percentage
        of the Nonhighly Compensated Employees.

        The Contribution Percentage for any Eligible Participant who is a
        Highly Compensated Employee for the Plan Year and who is eligible to
        have Contribution Percentage Amounts allocated to his account under two
        or more plans described in Code Section 401(a) or arrangements described
        in Code Section 401(k) that are maintained by the Employer or a
        Controlled Group member shall be determined as if the total of such
        Contribution Percentage Amounts was made under each plan.  If a Highly
        Compensated Employee participates in two or more cash or deferred
        arrangements that have different Plan Years, all cash or deferred
        arrangements ending with or within the same calendar year shall be
        treated as a single arrangement.  Notwithstanding the foregoing, certain
        plans shall be treated as separate if mandatorily disaggregated under
        the regulations under Code Section 401(m) or permissibly disaggregated
        as provided.

        In the event that this Plan satisfies the requirements of Code
        Sections 401(m), 401(a)(4), or 410(b) only if aggregated with one or
        more other plans, or if one or more other plans satisfy the requirements
        of Code sections only if aggregated with this Plan, then this section
        shall be applied by determining the Contribution Percentages of Eligible
        Participants as if all such plans were a single plan.  Plans may be
        aggregated in order to satisfy Code Section 401(m) only if they have the
        same Plan Year.

        For purposes of determining the Contribution Percentage of an Eligible
        Participant who is a five-percent owner or one of the ten most highly-
        paid Highly Compensated Employees, the Contribution Percentage Amounts
        and Compensation of such Participant shall include Contribution
        Percentage Amounts and Compensation for the Plan Year of Family Members.
        Family Members, with respect to Highly Compensated Employees, shall be
        disregarded as separate employees in determining the Contribution
        Percentage both for employees who are Nonhighly Compensated Employees
        and for employees who are Highly Compensated Employees.

        For purposes of determining the Contribution Percentage, Participant
        Contributions are considered to have been made in the Plan Year in which
        contributed to the Plan.  Matching Contributions and Qualified
        Nonelective Contributions will be considered made for a Plan Year if
        made no later than the end of the 12-month period beginning on the day
        after the close of the Plan Year.

                                       34
<PAGE>
 
        The Employer shall maintain records sufficient to demonstrate
        satisfaction of the Average Contribution Percentage test and the amount
        of Qualified Nonelective Contributions or Qualified Matching
        Contributions, or both, used in such test.

        The determination and treatment of the Contribution Percentage of any
        Participant shall satisfy such other requirements as may be prescribed
        by the Secretary of the Treasury.

        Notwithstanding any other provisions of this Plan, Excess Aggregate
        Contributions, plus any income and minus any loss allocable thereto,
        shall be forfeited, if not vested, or distributed, if vested, no later
        than the last day of each Plan Year to Participants to whose Accounts
        such Excess Aggregate Contributions were allocated for the preceding
        Plan Year.  If such Excess Aggregate Contributions are distributed more
        than 2 1/2 months after the last day of the Plan Year in which such
        excess amounts arose, a ten (10) percent excise tax will be imposed on
        the employer maintaining the plan with respect to those amounts.  Excess
        Aggregate Contributions will be distributed beginning with the Highly
        Compensated Employee(s) who has the greatest Contribution Percentage,
        reducing his contribution percentage to the next highest level.  Then,
        if necessary, reducing the Contribution Percentage of the Highly
        Compensated Employee at the next highest level, and continuing in this
        manner until the Actual Contribution Percentage of the Highly
        Compensated Group satisfies the Actual Contribution Percentage Test.
        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 Employee and Matching Contributions (or
        amounts treated as Matching Contributions) of each Family Member that is
        combined to determine the combined Contribution Percentage.  Excess
        Aggregate Contributions shall be treated as Annual Additions, as defined
        in the CONTRIBUTION LIMITATION SECTION of Article III, under the Plan.

        The Excess Aggregate Contributions shall be adjusted for income or
        loss.  The income or loss allocable to such Excess Aggregate
        Contributions shall be equal to the income or loss allocable to the
        Participant's Contribution Percentage Amounts for the Plan Year in which
        the excess occurred multiplied by a fraction.  The numerator of the
        fraction is the Excess Aggregate Contributions.  The denominator of the
        fraction is the closing balance without regard to any income or loss
        occurring during such Plan Year (as of the end of such Plan Year) of the
        Participant's Account resulting from Contribution Percentage Amounts.

        Excess Aggregate Contributions shall be distributed from the
        Participant's Account resulting from Participant Contributions that are
        not required as a condition of employment or participation or for
        obtaining additional benefits from Employer Contributions.  If such
        Excess Aggregate Contributions exceed the balance in the Participant's
        Account resulting from such Participant Contributions, the balance shall
        be forfeited, if not vested, or distributed, if vested, on a pro-rata
        basis from the Participant's Account resulting from Contribution
        Percentage Amounts.  These Forfeitures shall be used to offset the
        earliest Employer Contribution due after the Forfeiture arises.

                          INVESTMENT OF CONTRIBUTIONS

SECTION 4.01--INVESTMENT OF CONTRIBUTIONS.

    All Contributions are forwarded by the Employer to the Trustee to be
deposited in the Trust Fund.

    Investment of Contributions is governed by the provisions of the Trust, the
Group Contract and any other funding arrangement in which the Trust Fund is or
may be invested.  To the extent permitted by the Trust, Group Contract or other
funding arrangement, the parties named below shall direct the Contributions to
any of the accounts available under the Trust or Group Contract and may request
the transfer of assets resulting from those Contributions between such accounts.
A Participant may not direct the Trustee to invest the Participant's Account in
collectibles.  Collectibles means any work of art, rug or antique, metal or gem,
stamp or coin, alcoholic beverage or other tangible personal property specified
by the Secretary of Treasury.  To the extent that a Participant does not direct
the investment of his Account, such Account shall be invested ratably in the
accounts available under the Trust or Group Contract in the same manner as the
undirected Accounts of all other Participants.  The Vested Accounts of all
Inactive Participants may be segregated and invested separately from the
Accounts of all other Participants.

    The Trust Fund shall be valued at current fair market value as of the last
day of the last calendar month ending in the Plan Year and, at the discretion of
the Trustee, may be valued more frequently.  The valuation shall take into
consideration investment earnings credited, expenses charged, payments made and
changes in the value of the assets held in the Trust Fund.  The Account of a
Participant shall be credited with its share of the gains and losses of the
Trust Fund.  That part of a Participant's Account invested in a funding
arrangement which establishes an account or accounts for such Participant
thereunder shall be credited with the gain or loss from such account or
accounts.  That part of a Participant's Account which is invested in other
funding arrangements shall be credited with a proportionate share of the gain or
loss of such investments.  The share shall be determined by multiplying the gain
or loss of the investment by the ratio of the part of the Participant's Account
invested in such funding arrangement to the total of the Trust Fund invested in
such funding arrangement.

    At least annually, the Named Fiduciary shall review all pertinent Employee
information and Plan data in order to establish the funding policy of the Plan
and to determine appropriate methods of carrying out the Plan's objectives.  The
Named Fiduciary shall inform the Trustee and any Investment Manager of the
Plan's short-term and long-term financial needs so the investment policy can be
coordinated with the Plan's financial requirements.

    (a) Employer Contributions other than Elective Deferral Contributions:  The
        Participant shall direct the investment of such Employer Contributions
        and transfer of assets resulting from those Contributions.

    (b) Elective Deferral Contributions:  The Participant shall direct the
        investment of Elective Deferral Contributions and transfer of assets
        resulting from those Contributions.

    (c) Rollover Contributions:  The Participant shall direct the investment of
        Rollover Contributions and transfer of assets resulting from those
        Contributions.

                                       36
<PAGE>
 
    However, the Named Fiduciary may delegate to the Investment Manager
investment discretion for Contributions and Plan assets which are not subject to
Participant direction.

SECTION 4.01A--INVESTMENT IN QUALIFYING EMPLOYER SECURITIES.

    Participants in the Plan shall be entitled to invest all or any portion of
their Account in the Qualifying Employer Securities Fund.  Notwithstanding the
preceding sentence, no portion of the Participant's Account resulting from
Elective Deferral Contributions shall be invested in the Qualifying Employer
Securities Fund unless such investment would be in compliance with applicable
Federal and state securities laws (including any necessary filings under such
Federal and state securities laws) and the requirements of the Plan.

    Once an investment in the Qualifying Employer Securities Fund is made
available to Eligible Employees, then it shall continue to be available unless
the Plan and Trust is amended to disallow such available investment.  In the
absence of such election, such Eligible Employees shall be deemed to have
elected to have their Accounts invested wholly in other investment options of
the Investment Funds.  Once an election is made, it shall be considered to
continue until a new election is made.

    The Plan Administrator will allocate any dividends the Employer pays with
respect to amounts held in the Qualifying Employer Securities Fund to the
Account of a Participant according to the shares of Qualifying Employer
Securities held by the Participant, determined on the record date.  Any
dividends payable on the Qualifying Employer Securities shall, unless otherwise
directed by the Participant, be reinvested in additional shares of Qualifying
Employer Securities hereunder.

    If the securities of the Employer are not publicly traded and if no market
or an extremely thin market exists for the Qualifying Employer Securities, so
that a reasonable valuation may not be obtained from the market place, then such
Qualifying Employer Securities must be valued at least annually by an
independent appraiser who is not associated with the Employer, the Plan
Administrator, the Trustee, or any person related to any fiduciary under the
Plan.  The independent appraiser may be associated with a person who is merely a
contract administrator with respect to the Plan, but who exercises no
discretionary authority and is not a Plan fiduciary.

    If there is a public market for Qualifying Employer Securities of the type
held by the Plan, then the Plan Administrator may use as the value of the shares
the price at which such shares traded in such market, or an average of the bid
and asked prices for such shares in such market, provided that such value is
representative of the fair market value of such shares in the opinion of the
Plan Administrator.  If the Qualifying Employer Securities do not trade on the
annual valuation date or if the market is very thin on such date, then the Plan
Administrator may use the average of trade prices for a period of time ending on
such date, provided that such value is representative of the fair market value
of such shares in the opinion of the Plan Administrator.  The value of a
Participant's Account held in the Qualifying Employer Securities Fund may be
expressed in units.

    For purposes of determining the annual valuation of the Plan and for
reporting to Participants and regulatory authorities, the assets of the Plan
shall be valued at least annually on the Valuation Date which corresponds to the
last day of the Plan Year.  The fair market value of Qualifying Employer
Securities shall be determined on such a Valuation Date.  The average of the bid
and asked prices of Qualifying Employer Securities as of the date of the
transaction shall apply for purposes of valuing distributions and other
transactions of the Plan to the extent such value is representative of the fair
market value of such shares in the opinion of the Plan Administrator.

                                       37
<PAGE>
 
    All purchases of Qualifying Employer Securities shall be made at a price, or
prices, which, in the judgment of the Plan Administrator, do not exceed the fair
market value of such Qualifying Employer Securities.

    In the event that the Trustee acquires shares of Qualifying Employer
Securities by purchase from a "disqualified person" as defined in Code Section
4975(e)(2) or from a "party in interest" as defined in ERISA Section 3(14), in
exchange for cash or other assets of the Trust, the terms of such purchase shall
contain the provision that in the event that there is a final determination by
the Internal Revenue Service, the Department of Labor, or court of competent
jurisdiction that a fair market value of such shares of Qualifying Employer
Securities, as of the date of purchase was less than the purchase price paid by
the Trustee, then the seller shall pay or transfer, as the case may be, to the
Trustee, an amount of cash, shares of Qualifying Employer Securities, or any
combination thereof equal in value to the difference between the purchase price
and said fair market value for all such shares.  In the event that cash and/or
shares of Qualifying Employer Securities are paid and/or transferred to the
Trustee under this provision, shares of Qualifying Employer Securities shall be
valued at their fair market value as of the date of said purchase, and interest
at a reasonable rate from the date of purchase to the date of payment shall be
paid by the seller on the amount of cash paid.

    The Plan Administrator may direct the Trustee to sell, resell or otherwise
dispose of Qualifying Employer Securities to any person, including the Employer,
provided that any such sales to any disqualified person or a party in interest,
including the Employer, will be made at not less than the fair market value and
no commission is charged.  Any such sale shall be made in conformance with
Section 408(e) of ERISA.

    In the event the Plan Administrator directs the Trustee to dispose of any
Qualifying Employer Securities held as Trust assets under circumstances which
require registration and/or qualification of the securities under applicable
Federal or state securities laws, then the Employer, at its own expense, will
take or cause to be taken any and all such action as may be necessary or
appropriate to effect such registration and/or qualification.

    If a Security Exchange Commission (SEC) filing is required, the Qualifying
Employer Securities provisions set forth in this Plan restatement will not be
made available to Participants until the later of the effective date of the Plan
restatement or the date the Plan and any other necessary documentation has been
filed for registration with the SEC by the Employer.

                                   ARTICLE V

                                    BENEFITS

SECTION 5.01--RETIREMENT BENEFITS.

    On a Participant's Retirement Date, his Vested Account shall be distributed
to him according to the distribution of benefits provisions of Article VI and
the provisions of the SMALL AMOUNTS SECTION of Article IX.

SECTION 5.02--DEATH BENEFITS.

    If a Participant dies before his Annuity Starting Date, his Vested Account
shall be distributed according to the distribution of benefits provisions of
Article VI and the provisions of the SMALL AMOUNTS SECTION of Article IX.

SECTION 5.03--VESTED BENEFITS.

    A Participant may receive a distribution of his Vested Account at any time
after he ceases to be an Employee, provided he has not again become an Employee.
If such amount is not payable under the provisions of the SMALL AMOUNTS SECTION
of Article IX, it will be distributed only if the Participant so elects.  The
Participant's election shall be subject to the requirements in the ELECTION
PROCEDURES SECTION of Article VI for a qualified election of a retirement
benefit.

    If a Participant does not receive an earlier distribution according to the
provisions of this section or the SMALL AMOUNTS SECTION of Article IX, upon his
Retirement Date or death, his Vested Account shall be applied according to the
provisions of the RETIREMENT BENEFITS SECTION or the DEATH BENEFITS SECTION of
Article V.

    The Nonvested Account of a Participant who has ceased to be an Employee
shall remain a part of his Account until it becomes a Forfeiture; provided,
however, if the Participant again becomes an Employee so that his Vesting
Percentage can increase, the Nonvested Account may become a part of his Vested
Account.

SECTION 5.04--WHEN BENEFITS START.

    Benefits under the Plan begin when a Participant retires, dies or ceases to
be an Employee, whichever applies, as provided in the preceding sections of this
article.  Benefits which begin before Normal Retirement Date for a Participant
who became Totally and Permanently Disabled when he was an Employee shall be
deemed to begin because he is Totally and Permanently Disabled.  The start of
benefits is subject to the qualified election procedures of Article VI.

    Unless otherwise elected, benefits shall begin before the sixtieth day
following the close of the Plan Year in which the latest date below occurs:

    (a) The date the Participant attains age 65 (Normal Retirement Age, if
        earlier).

    (b) The tenth anniversary of the Participant's Entry Date.

                                       39
<PAGE>
 
    (c) The date the Participant ceases to be an Employee.

    Notwithstanding the foregoing, the failure of a Participant and spouse to
consent to a distribution while a benefit is immediately distributable, within
the meaning of the ELECTION PROCEDURES SECTION of Article VI, shall be deemed to
be an election to defer commencement of payment of any benefit sufficient to
satisfy this section.

    The Participant may elect to have his benefits begin after the latest date
for beginning benefits described above, subject to the provisions of this
section.  The Participant shall make the election in writing and deliver the
signed statement of election to the Plan Administrator before Normal Retirement
Date or the date he ceases to be an Employee, if later.  The election must
describe the form of distribution and the date the benefits will begin.  The
Participant shall not elect a date for beginning benefits or a form of
distribution that would result in a benefit payable when he dies which would be
more than incidental within the meaning of governmental regulations.

    Benefits shall begin by the Participant's Required Beginning Date, as
defined in the OPTIONAL FORMS OF DISTRIBUTION AND DISTRIBUTION REQUIREMENTS
SECTION of Article VI.

    Contributions which are used to compute the Actual Deferral Percentage, as
defined in the EXCESS AMOUNTS SECTION of Article III, may be distributed upon
disposition by the Employer of substantially all of the assets (within the
meaning of Code Section 409(d)(2)) used by the Employer in a trade or business
or disposition by the Employer of the Employer's interest in a subsidiary
(within the meaning of Code Section 409(d)(3)) if the transferee corporation is
not a Controlled Group member, the Employee continues employment with the
transferee corporation and the transferor corporation continues to maintain the
Plan.  Such distributions made after March 31, 1988, must be made in a single
sum.

SECTION 5.05--WITHDRAWAL PRIVILEGES.

    A Participant may withdraw all or any portion of his Vested Account which
results from the following Contributions

    Elective Deferral Contributions
    Matching Contributions
    Rollover Contributions

in the event of hardship due to an immediate and heavy financial need.
Withdrawals from the Participant's Account resulting from Elective Deferral
Contributions shall be limited to the amount of the Participant's Elective
Deferral Contributions.  Immediate and heavy financial need shall be limited to:
(i) expenses incurred or necessary for medical care, described in Code Section
213(d), of the Participant, the Participant's spouse, or any dependents of the
Participant (as defined in Code Section 152); (ii) purchase (excluding mortgage
payments) of a principal residence for the Participant; (iii) payment of tuition
and related educational fees and the payment of room and board expenses for the
next 12 months of post-secondary education for the Participant, his spouse,
children or dependents; (iv) the need to prevent the eviction of the Participant
from his principal residence or foreclosure on the mortgage of the Participant's
principal residence; or (v) any other distribution which is deemed by the
Commissioner of Internal Revenue to be made on account of immediate and heavy
financial need as provided in Treasury regulations.  The Participant's request
for a withdrawal shall include his written statement that an immediate and heavy
financial need exists and explain its nature.

                                       40
<PAGE>
 
    No withdrawal shall be allowed which is not necessary to satisfy such
immediate and heavy financial need.  Such withdrawal shall be deemed necessary
only if all of the following requirements are met:  (i) the distribution is not
in excess of the amount of the immediate and heavy financial need of the
Participant (including amounts necessary to pay any Federal, state or local
income taxes or penalties reasonably anticipated to result from the
distribution); (ii) the Participant has obtained all distributions, other than
hardship distributions, and all nontaxable loans currently available under all
plans maintained by the Employer; (iii) the Plan, and all other plans maintained
by the Employer, provide that the Participant's elective contributions and
employee contributions will be suspended for at least 12 months after receipt of
the hardship distribution; and (iv) the Plan, and all other plans maintained by
the Employer, provide that the Participant may not make elective contributions
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
contributions for the taxable year of the hardship distribution.  The Plan will
suspend elective contributions and employee contributions for 12 months and
limit elective deferrals as provided in the preceding sentence.  A Participant
shall not cease to be an Eligible Participant, as defined in the EXCESS AMOUNTS
SECTION of Article III, merely because his elective contributions or employee
contributions are suspended.

    A request for withdrawal shall be in writing on a form furnished for that
purpose and delivered to the Plan Administrator before the withdrawal is to
occur.  The Participant's request shall be subject to the requirements in the
ELECTION PROCEDURES SECTION of Article VI for a qualified election of a
retirement benefit payable in a form other than a Qualified Joint and Survivor
Form.

    A forfeiture shall not occur solely as a result of a withdrawal.

SECTION 5.06--LOANS TO PARTICIPANTS.

    Loans shall be made available to all Participants on a reasonably equivalent
basis.  For purposes of this section, Participant means any Participant or
Beneficiary who is a party-in-interest, within the meaning of Section 3(14) of
the Employee Retirement Income Security Act of 1974 (ERISA).  Loans shall not be
made to highly compensated employees, as defined in Code Section 414(q), in an
amount greater than the amount made available to other Participants.

    No loans will be made to any shareholder-employee or owner-employee.  For
purposes of this requirement, a shareholder-employee means an employee or
officer of an electing small business (Subchapter S) corporation who owns (or is
considered as owning within the meaning of Code Section 318(a)(1)), on any day
during the taxable year of such corporation, more than 5% of the outstanding
stock of the corporation.

    A loan to a Participant shall be a Participant-directed investment of his
Account.  No Account other than the borrowing Participant's Account shall share
in the interest paid on the loan or bear any expense or loss incurred because of
the loan.  The portion of the Participant's Account held in the Qualifying
Employer Securities Fund may be redeemed for purposes of a loan only after the
amount held in the Participant's other investment options have been depleted.

    The number of outstanding loans shall be limited to one.  No more than one
loan will be approved for any Participant in any 12-month period.  The minimum
amount of any loan shall be $1,000.

    Loans must be adequately secured and bear a reasonable rate of interest.

                                       41
<PAGE>
 
    The amount of the loan shall not exceed the maximum amount that may be
treated as a loan under Code Section 72(p) (rather than a distribution) to the
Participant and shall be equal to the lesser of (a) or (b) below:

    (a) $50,000 reduced by the highest outstanding loan balance of loans during
        the one-year period ending on the day before the new loan is made.

    (b) The greater of (1) or (2), reduced by (3) below:

        (1) One-half of the Participant's Vested Account.

        (2) $10,000.

        (3) Any outstanding loan balance on the date the new loan is made.

For purposes of this maximum, a Participant's Vested Account does not include
any accumulated deductible employee contributions, as defined in Code Section
72(o)(5)(B), and all qualified employer plans, as defined in Code Section
72(p)(4), of the Employer and any Controlled Group member shall be treated as
one plan.

    The foregoing notwithstanding, the amount of such loan shall not exceed 50%
of the amount of the Participant's Vested Account.   For purposes of this
maximum, a Participant's Vested Account does not include any accumulated
deductible employee contributions, as defined in Code Section 72(o)(5)(B).  No
collateral other than a portion of the Participant's Vested Account (as limited
above) shall be accepted.  The Loan Administrator shall determine if the
collateral is adequate for the amount of the loan requested.

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

    If a valid spousal consent has been obtained in accordance with the above,
then, notwithstanding any other provision of this Plan, the portion of the
Participant's Vested Account used as a security interest held by the Plan by
reason of a loan outstanding to the Participant shall be taken into account for
purposes of determining the amount of the Vested Account payable at the time of
death or distribution, but only if the reduction is used as repayment of the
loan.  If less than 100% of the Participant's Vested Account (determined without
regard to the preceding sentence) is payable to the surviving spouse, then the
Vested Account shall be adjusted by first reducing the Vested Account by the
amount of the security used as repayment of the loan, and then determining the
benefit payable to the surviving spouse.

    Each loan shall bear a reasonable fixed rate of interest to be determined by
the Loan Administrator.  In determining the interest rate, the Loan
Administrator shall take into consideration fixed interest rates currently being
charged by commercial lenders for loans of comparable risk on similar terms and
for similar durations, so that the interest will provide for a return
commensurate with rates currently charged by commercial lenders for loans made
under similar circumstances.  The Loan Administrator shall not discriminate
among Participants in the matter of interest rates; but loans granted at
different times may bear different interest rates in accordance with the current
appropriate standards.

                                       42
<PAGE>
 
    The loan shall by its terms require that repayment (principal and interest)
be amortized in level payments, not less frequently than quarterly, over a
period not extending beyond five years from the date of the loan.  The period of
repayment for any loan shall be arrived at by mutual agreement between the Loan
Administrator and the Participant.

    The Participant shall make a written application for a loan from the Plan on
forms provided by the Loan Administrator.  The application must specify the
amount and duration requested.  No loan will be approved unless the Participant
is creditworthy.  The Participant must grant authority to the Loan Administrator
to investigate the Participant's creditworthiness so that the loan application
may be properly considered.

    Information contained in the application for the loan concerning the income,
liabilities, and assets of the Participant will be evaluated to determine
whether there is a reasonable expectation that the Participant will be able to
satisfy payments on the loan as due.  Additionally, the Loan Administrator will
pursue any appropriate further investigations concerning the creditworthiness
and/or credit history of the Participant to determine whether a loan should be
approved.

    Each loan shall be fully documented in the form of a promissory note signed
by the Participant for the face amount of the loan, together with interest
determined as specified above.

    There will be an assignment of collateral to the Plan executed at the time
the loan is made.

    In those cases where repayment through payroll deduction by the Employer is
available, installments are so payable, and a payroll deduction agreement will
be executed by the Participant at the time of making the loan.

    Where payroll deduction is not available, payments are to be timely made.

    Any payment that is not by payroll deduction shall be made payable to the
Employer or Trustee, as specified in the promissory note, and delivered to the
Loan Administrator, including prepayments, service fees and penalties, if any,
and other amounts due under the note.

    The promissory note may provide for reasonable late payment penalties and/or
service fees.  Any penalties or service fees shall be applied to all
Participants in a nondiscriminatory manner.  If the promissory note so provides,
such amounts may be assessed and collected from the Account of the Participant
as part of the loan balance.

    Each loan may be paid prior to maturity, in part or in full, without penalty
or service fee, except as may be set out in the promissory note.

    If any amount remains unpaid for more than 31 days after due, a default is
deemed to occur.

    Upon default, the Plan has the right to pursue any remedy available by law
to satisfy the amount due, along with accrued interest, including the right to
enforce its claim against the security pledged and execute upon the collateral
as allowed by law.

    If any payment of principal or interest or any other amount due under the
promissory note, or any portion thereof, is not made for a period of 90 days
after due, the entire principal balance whether or not otherwise then due, shall
become immediately due and payable without demand or notice, and subject to
collection or 

                                       43
<PAGE>
 
satisfaction by any lawful means, including specifically but not limited to the
right to enforce the claim against the security pledged and to execute upon the
collateral as allowed by law.

    In the event of default, foreclosure on the note and attachment of security
or use of amounts pledged to satisfy the amount then due, will not occur until a
distributable event occurs in accordance with the Plan, and will not occur to an
extent greater than the amount then available upon any distributable event which
has occurred under the Plan.

    All reasonable costs and expenses, including but not limited to attorney's
fees, incurred by the Plan in connection with any default or in any proceeding
to enforce any provision of a promissory note or instrument by which a
promissory note for a Participant loan is secured, shall be assessed and
collected from the Account of the Participant as part of the loan balance.

    If payroll deduction is being utilized, in the event that a Participant's
available payroll deduction amounts in any given month are insufficient to
satisfy the total amount due, there will be an increase in the amount taken
subsequently, sufficient to make up the amount that is then due.  If the
subsequent deduction is also insufficient to satisfy the amount due within 31
days, a default is deemed to occur as above.  If any amount remains past due
more than 90 days, the entire principal amount, whether or not otherwise then
due, along with interest then accrued and any other amount then due under the
promissory note, shall become due and payable, as above.

    If the Participant ceases to be a party-in-interest (as defined in this
section) the balance of the outstanding loan becomes due and payable, and the
Participant's Vested Account will be used as available for distribution(s) to
pay the outstanding loan.  The Participant's Vested Account will not be used to
pay any amount due under the outstanding loan before the date which is 31 days
after the date he ceased to be an Employee, and the Participant may elect to
repay the outstanding loan with interest on the day of repayment.  If no
distributable event has occurred under the Plan at the time that the
Participant's Vested Account would otherwise be used under this provision to pay
any amount due under the outstanding loan, this will not occur until the time,
or in excess of the extent to which, a distributable event occurs under the
Plan.

                                   ARTICLE VI

                            DISTRIBUTION OF BENEFITS

SECTION 6.01--AUTOMATIC FORMS OF DISTRIBUTION.

    Unless a qualified election of an optional form of benefit has been made
within the election period (see the ELECTION PROCEDURES SECTION of Article VI),
the automatic form of benefit payable to or on behalf of a Participant is
determined as follows:

    (a) The automatic form of retirement benefit for a Participant who does not
        die before his Annuity Starting Date shall be the Qualified Joint and
        Survivor Form.

    (b) The automatic form of death benefit for a Participant who dies before
        his Annuity Starting Date shall be:

        (1) A Qualified Preretirement Survivor Annuity for a Participant who has
            a spouse to whom he has been continuously married throughout the
            one-year period ending on the date of his death.  The spouse may
            elect to start receiving the death benefit on any first day of the
            month on or after the Participant dies and before the date the
            Participant would have been age 70 1/2.  If the spouse dies before
            benefits start, the Participant's Vested Account, determined as of
            the date of the spouse's death, shall be paid to the spouse's
            Beneficiary.

        (2) A single-sum payment to the Participant's Beneficiary for a
            Participant who does not have a spouse who is entitled to a
            Qualified Preretirement Survivor Annuity.

        Before a death benefit will be paid on account of the death of a
        Participant who does not have a spouse who is entitled to a Qualified
        Preretirement Survivor Annuity, it must be established to the
        satisfaction of a plan representative that the Participant does not have
        such a spouse.

SECTION 6.02--OPTIONAL FORMS OF DISTRIBUTION AND DISTRIBUTION REQUIREMENTS.

    (a) For purposes of this section, the following terms are defined:

        Applicable Life Expectancy means Life Expectancy (or Joint and Last
        Survivor Expectancy) calculated using the attained age of the
        Participant (or Designated Beneficiary) as of the Participant's (or
        Designated Beneficiary's) birthday in the applicable calendar year
        reduced by one for each calendar year which has elapsed since the date
        Life Expectancy was first calculated.  If Life Expectancy is being
        recalculated, the Applicable Life Expectancy shall be the Life
        Expectancy so recalculated.  The applicable calendar year shall be the
        first Distribution Calendar Year, and if Life Expectancy is being
        recalculated such succeeding calendar year.

        Designated Beneficiary means the individual who is designated as the
        beneficiary under the Plan in accordance with Code Section 401(a)(9) and
        the regulations thereunder.

        Distribution Calendar Year means a calendar year for which a minimum
        distribution is required.  For distributions beginning before the
        Participant's death, the first Distribution Calendar Year is the

                                       45
<PAGE>
 
        calendar year immediately preceding the calendar year which contains the
        Participant's Required Beginning Date.  For distributions beginning
        after the Participant's death, the first Distribution Calendar Year is
        the calendar year in which distributions are required to begin pursuant
        to (e) below.

        Joint and Last Survivor Expectancy means joint and last survivor
        expectancy computed by use of the expected return multiples in Table VI
        of section 1.72-9 of the Income Tax Regulations.

        Unless otherwise elected by the Participant (or spouse, in the case of
        distributions described in (e)(2)(ii) below) by the time distributions
        are required to begin, life expectancies shall be recalculated annually.
        Such election shall be irrevocable as to the Participant (or spouse) and
        shall apply to all subsequent years.  The life expectancy of a nonspouse
        Beneficiary may not be recalculated.

        Life Expectancy means life expectancy computed by use of the expected
        return multiples in Table V of section 1.72-9 of the Income Tax
        Regulations.

        Unless otherwise elected by the Participant (or spouse, in the case of
        distributions described in (e)(2)(ii) below) by the time distributions
        are required to begin, life expectancies shall be recalculated annually.
        Such election shall be irrevocable as to the Participant (or spouse) and
        shall apply to all subsequent years.  The life expectancy of a nonspouse
        Beneficiary may not be recalculated.

        Participant's Benefit means

        (1) The Account balance as of the last valuation date in the calendar
            year immediately preceding the Distribution Calendar Year (valuation
            calendar year) increased by the amount of any contributions or
            forfeitures allocated to the Account balance as of the dates in the
            valuation calendar year after the valuation date and decreased by
            distributions made in the valuation calendar year after the
            valuation date.

        (2) For purposes of (1) above, if any portion of the minimum
            distribution for the first Distribution Calendar Year is made in the
            second Distribution Calendar Year on or before the Required
            Beginning Date, the amount of the minimum distribution made in the
            second Distribution Calendar Year shall be treated as if it had been
            made in the immediately preceding Distribution Calendar Year.

        Required Beginning Date means, for a Participant, the first day of
        April of the calendar year following the calendar year in which the
        Participant attains age 70 1/2, unless otherwise provided in (1), (2) or
        (3) below:

        (1) The Required Beginning Date for a Participant who attains age 70 1/2
            before January 1, 1988, and who is not a 5-percent owner is the
            first day of April of the calendar year following the calendar year
            in which the later of retirement or attainment of age 70 1/2 occurs.

        (2) The Required Beginning Date for a Participant who attains age 70 1/2
            before January 1, 1988, and who is a 5-percent owner is the first
            day of April of the calendar year following the later of

                                       46
<PAGE>
 
            (i)  the calendar year in which the Participant attains age 70 1/2,
                 or

            (ii) the earlier of the calendar year with or within which ends the
                 Plan Year in which the Participant becomes a 5-percent owner,
                 or the calendar year in which the Participant retires.

        (3) The Required Beginning Date of a Participant who is not a 5-percent
            owner and who attains age 70 1/2 during 1988 and who has not retired
            as of January 1, 1989, is April 1, 1990.

        A Participant is treated as a 5-percent owner for purposes of this
        section if such Participant is a 5-percent owner as defined in Code
        Section 416(i) (determined in accordance with Code Section 416 but
        without regard to whether the Plan is top-heavy) at any time during the
        Plan Year ending with or within the calendar year in which such owner
        attains age 66 1/2 or any subsequent Plan Year.

        Once distributions have begun to a 5-percent owner under this section,
        they must continue to be distributed, even if the Participant ceases to
        be a 5-percent owner in a subsequent year.

    (b) The optional forms of retirement benefit shall be the following:  a
        straight life annuity; single life annuities with certain periods of
        five, ten or fifteen years; a single life annuity with installment
        refund; survivorship life annuities with installment refund and
        survivorship percentages of 50, 66 2/3 or 100; fixed period annuities
        for any period of whole months which is not less than 60 and does not
        exceed the Life Expectancy of the Participant and the named Beneficiary
        as provided in (d) below where the Life Expectancy is not recalculated;
        and a series of installments chosen by the Participant with a minimum
        payment each year beginning with the year the Participant turns age 
        70 1/2. The payment for the first year in which a minimum payment is
        required will be made by April 1 of the following calendar year. The
        payment for the second year and each successive year will be made by
        December 31 of that year. The minimum payment will be based on a period
        equal to the Joint and Last Survivor Expectancy of the Participant and
        the Participant's spouse, if any, as provided in (d) below where the
        Joint and Last Survivor Expectancy is recalculated. The balance of the
        Participant's Vested Account, if any, will be payable on the
        Participant's death to his Beneficiary in a single sum. The Participant
        may also elect to receive his Vested Account in a single-sum payment.

        Election of an optional form is subject to the qualified election
        provisions of Article VI.

        Any annuity contract distributed shall be nontransferable.  The terms
        of any annuity contract purchased and distributed by the Plan to a
        Participant or spouse shall comply with the requirements of this Plan.

    (c) The optional forms of death benefit are a single-sum payment and any
        annuity that is an optional form of retirement benefit.  However, a
        series of installments shall not be available if the Beneficiary is not
        the spouse of the deceased Participant.

    (d) Subject to the AUTOMATIC FORMS OF DISTRIBUTION SECTION of Article VI,
        joint and survivor annuity requirements, the requirements of this
        section shall apply to any distribution of a Participant's interest and
        will take precedence over any inconsistent provisions of this Plan.
        Unless otherwise specified, the provisions of this section apply to
        calendar years beginning after December 31, 1984.

                                       47

        All distributions required under this section shall be determined and
        made in accordance with the proposed regulations under Code Section
        401(a)(9), including the minimum distribution incidental benefit
        requirement of section 1.401(a)(9)-2 of the proposed regulations.

        The entire interest of a Participant must be distributed or begin to
        be distributed no later than the Participant's Required Beginning Date.

        As of the first Distribution Calendar Year, distributions, if not made
        in a single sum, may only be made over one of the following periods (or
        combination thereof):

        (1) the life of the Participant,

        (2) the life of the Participant and a Designated Beneficiary,

        (3) a period certain not extending beyond the Life Expectancy of the
            Participant, or

        (4) a period certain not extending beyond the Joint and Last Survivor
            Expectancy of the Participant and a Designated Beneficiary.

        If the Participant's interest is to be distributed in other than a
        single sum, the following minimum distribution rules shall apply on or
        after the Required Beginning Date:

        (5) Individual account:

            (i) If a Participant's Benefit is to be distributed over

                 (a) a period not extending beyond the Life Expectancy of the
                     Participant or the Joint Life and Last Survivor Expectancy
                     of the Participant and the Participant's Designated
                     Beneficiary or

                 (b) a period not extending beyond the Life Expectancy of the
                     Designated Beneficiary,

                the amount required to be distributed for each calendar year
                beginning with the distributions for the first Distribution
                Calendar Year, must be at least equal to the quotient obtained
                by dividing the Participant's Benefit by the Applicable Life
                Expectancy.

           (ii) For calendar years beginning before January 1, 1989, if the
                Participant's spouse is not the Designated Beneficiary, the
                method of distribution selected must assure that at least 50% of
                the present value of the amount available for distribution is
                paid within the Life Expectancy of the Participant.

         (iii)  For calendar years beginning after December 31, 1988, the
                amount to be distributed each year, beginning with distributions
                for the first Distribution Calendar Year shall not be less than
                the quotient obtained by dividing the Participant's Benefit by
                the lesser of

                 (a) the Applicable Life Expectancy or

                                       48
<PAGE>
 
                 (b) if the Participant's spouse is not the Designated
                     Beneficiary, the applicable divisor determined from the
                     table set forth in Q&A-4 of section 1.401(a)(9)-2 of the
                     proposed regulations.

                Distributions after the death of the Participant shall be
                distributed using the Applicable Life Expectancy in (5)(i) above
                as the relevant divisor without regard to Proposed Regulations
                section 1.401(a)(9)-2.

          (iv) The minimum distribution required for the Participant's first
                Distribution Calendar Year must be made on or before the
                Participant's Required Beginning Date.  The minimum distribution
                for the Distribution Calendar Year for other calendar years,
                including the minimum distribution for the Distribution Calendar
                Year in which the Participant's Required Beginning Date occurs,
                must be made on or before December 31 of that Distribution
                Calendar Year.

        (6) Other forms:

            (i) If the Participant's Benefit is distributed in the form of an
                annuity purchased from an insurance company, distributions
                thereunder shall be made in accordance with the requirements of
                Code Section 401(a)(9) and the proposed regulations thereunder.

    (e) Death distribution provisions:

        (1) Distribution beginning before death.  If the Participant dies after
            distribution of his interest has begun, the remaining portion of
            such interest will continue to be distributed at least as rapidly as
            under the method of distribution being used prior to the
            Participant's death.

        (2) Distribution beginning after death.  If the Participant dies before
            distribution of his interest begins, distribution of the
            Participant's entire interest shall be completed by December 31 of
            the calendar year containing the fifth anniversary of the
            Participant's death except to the extent that an election is made to
            receive distributions in accordance with (i) or (ii) below:

            (i) if any portion of the Participant's interest is payable to a
                Designated Beneficiary, distributions may be made over the life
                or over a period certain not greater than the Life Expectancy of
                the Designated Beneficiary commencing on or before December 31
                of the calendar year immediately following the calendar year in
                which the Participant died;

           (ii) if the Designated Beneficiary is the Participant's surviving
                spouse, the date distributions are required to begin in
                accordance with (i) above shall not be earlier than the later of

                (a) December 31 of the calendar year immediately following the
                    calendar year in which the Participant died and
                (b) December 31 of the calendar year in which the Participant
                    would have attained age 70 1/2.

                                       49
<PAGE>
 
            If the Participant has not made an election pursuant to this
            (e)(2) by the time of his death, the Participant's Designated
            Beneficiary must elect the method of distribution no later than the
            earlier of

            (iii)  December 31 of the calendar year in which distributions would
                   be required to begin under this subparagraph, or

            (iv)   December 31 of the calendar year which contains the fifth
                   anniversary of the date of death of the Participant.

            If the Participant has no Designated Beneficiary, or if the
            Designated Beneficiary does not elect a method of distribution,
            distribution of the Participant's entire interest must be completed
            by December 31 of the calendar year containing the fifth anniversary
            of the Participant's death.

        (3) For purposes of (e)(2) above, if the surviving spouse dies after the
            Participant, but before payments to such spouse begin, the
            provisions of (e)(2) above, with the exception of (e)(2)(ii)
            therein, shall be applied as if the surviving spouse were the
            Participant.

        (4) For purposes of this (e), any amount paid to a child of the
            Participant will be treated as if it had been paid to the surviving
            spouse if the amount becomes payable to the surviving spouse when
            the child reaches the age of majority.

        (5) For purposes of this (e), distribution of a Participant's interest
            is considered to begin on the Participant's Required Beginning Date
            (or if (e)(3) above is applicable, the date distribution is required
            to begin to the surviving spouse pursuant to (e)(2) above).  If
            distribution in the form of an annuity irrevocably commences to the
            Participant before the Required Beginning Date, the date
            distribution is considered to begin is the date distribution
            actually commences.

SECTION 6.02A--DISTRIBUTIONS IN QUALIFYING EMPLOYER SECURITIES.

    In lieu of the cash distributions permitted under Section 6.02 above, any
portion of the Participant's Vested Account held in the Qualifying Employer
Securities Fund may be distributed in kind upon the election of the Participant.
Fractional shares valued as of the most recent Valuation Date shall be paid in
cash.  The distribution shall include any dividends (cash or stock) on such
whole shares or any additional shares received as a result of a stock split or
any other adjustment to such whole shares since the Valuation Date preceding the
date of distribution.

    Election of such distribution is subject to the qualified election
provisions of Article VI.

SECTION 6.03--ELECTION PROCEDURES.

    The Participant, Beneficiary, or spouse shall make any election under this
section in writing.  The Plan Administrator may require such individual to
complete and sign any necessary documents as to the provisions to be made.  Any
election permitted under (a) and (b) below shall be subject to the qualified
election provisions of (c) below.

                                       50
<PAGE>
 
    (a) Retirement Benefits.  A Participant may elect his Beneficiary or
        Contingent Annuitant and may elect to have retirement benefits
        distributed under any of the optional forms of retirement benefit
        described in the OPTIONAL FORMS OF DISTRIBUTION AND DISTRIBUTION
        REQUIREMENTS SECTION of Article VI.

    (b) Death Benefits.  A Participant may elect his Beneficiary and may elect
        to have death benefits distributed under any of the optional forms of
        death benefit described in the OPTIONAL FORMS OF DISTRIBUTION AND
        DISTRIBUTION REQUIREMENTS SECTION of Article VI.

        If the Participant has not elected an optional form of distribution
        for the death benefit payable to his Beneficiary, the Beneficiary may,
        for his own benefit, elect the form of distribution, in like manner as a
        Participant.

        The Participant may waive the Qualified Preretirement Survivor Annuity
        by naming someone other than his spouse as Beneficiary.

        In lieu of the Qualified Preretirement Survivor Annuity described in
        the AUTOMATIC FORMS OF DISTRIBUTION SECTION of Article VI, the spouse
        may, for his own benefit, waive the Qualified Preretirement Survivor
        Annuity by electing to have the benefit distributed under any of the
        optional forms of death benefit described in the OPTIONAL FORMS OF
        DISTRIBUTION AND DISTRIBUTION REQUIREMENTS SECTION of Article VI.

    (c) Qualified Election.  The Participant, Beneficiary or spouse may make an
        election at any time during the election period.  The Participant,
        Beneficiary, or spouse may revoke the election made (or make a new
        election) at any time and any number of times during the election
        period.  An election is effective only if it meets the consent
        requirements below.

        The election period as to retirement benefits is the 90-day period
        ending on the Annuity Starting Date.  An election to waive the Qualified
        Joint and Survivor Form may not be made before the date he is provided
        with the notice of the ability to waive the Qualified Joint and Survivor
        Form.  If the Participant elects the series of installments, he may
        elect on any later date to have the balance of his Vested Account paid
        under any of the optional forms of retirement benefit available under
        the Plan.  His election period for this election is the 90-day period
        ending on the Annuity Starting Date for the optional form of retirement
        benefit elected.

        A Participant may make an election as to death benefits at any time
        before he dies.  The spouse's election period begins on the date the
        Participant dies and ends on the date benefits begin.  The Beneficiary's
        election period begins on the date the Participant dies and ends on the
        date benefits begin.  An election to waive the Qualified Preretirement
        Survivor Annuity may not be made by the Participant before the date he
        is provided with the notice of the ability to waive the Qualified
        Preretirement Survivor Annuity.  A Participant's election to waive the
        Qualified Preretirement Survivor Annuity which is made before the first
        day of the Plan Year in which he reaches age 35 shall become invalid on
        such date.  An election made by a Participant after he ceases to be an
        Employee will not become invalid on the first day of the Plan Year in
        which he reaches age 35 with respect to death benefits from that part of
        his Account resulting from Contributions made before he ceased to be an
        Employee.

        If the Participant's Vested Account has at any time exceeded $3,500,
        any benefit which is (1) immediately distributable or (2) payable in a
        form other than a Qualified Joint and Survivor Form or 

                                       51
<PAGE>
 
        a Qualified Preretirement Survivor Annuity requires the consent of the
        Participant and the Participant's spouse (or where either the
        Participant or the spouse has died, the survivor). The consent of the
        Participant or spouse to a benefit which is immediately distributable
        must not be made before the date the Participant or spouse is provided
        with the notice of the ability to defer the distribution. Such consent
        shall be made in writing. The consent shall not be made more than 90
        days before the Annuity Starting Date. Spousal consent is not required
        for a benefit which is immediately distributable in a Qualified Joint
        and Survivor Form. Furthermore, if spousal consent is not required
        because the Participant is electing an optional form of retirement
        benefit that is not a life annuity pursuant to (d) below, only the
        Participant need consent to the distribution of a benefit payable in a
        form that is not a life annuity and which is immediately distributable.
        Neither the consent of the Participant nor the Participant's spouse
        shall be required to the extent that a distribution is required to
        satisfy Code Section 401(a)(9) or Code Section 415. In addition, upon
        termination of this Plan if the Plan does not offer an annuity option
        (purchased from a commercial provider), the Participant's Account
        balance may, without the Participant's consent, be distributed to the
        Participant or transferred to another defined contribution plan (other
        than an employee stock ownership plan as defined in Code Section
        4975(e)(7)) within the same Controlled Group. A benefit is immediately
        distributable if any part of the benefit could be distributed to the
        Participant (or surviving spouse) before the Participant attains (or
        would have attained if not deceased) the older of Normal Retirement Age
        or age 62. If the Qualified Joint and Survivor Form is waived, the
        spouse has the right to limit consent only to a specific Beneficiary or
        a specific form of benefit. The spouse can relinquish one or both such
        rights. Such consent shall be made in writing. The consent shall not be
        made more than 90 days before the Annuity Starting Date. If the
        Qualified Preretirement Survivor Annuity is waived, the spouse has the
        right to limit consent only to a specific Beneficiary. Such consent
        shall be in writing. The spouse's consent shall be witnessed by a plan
        representative or notary public. The spouse's consent must acknowledge
        the effect of the election, including that the spouse had the right to
        limit consent only to a specific Beneficiary or a specific form of
        benefit, if applicable, and that the relinquishment of one or both such
        rights was voluntary. Unless the consent of the spouse expressly permits
        designations by the Participant without a requirement of further consent
        by the spouse, the spouse's consent must be limited to the form of
        benefit, if applicable, and the Beneficiary (including any Contingent
        Annuitant), class of Beneficiaries, or contingent Beneficiary named in
        the election. Spousal consent is not required, however, if the
        Participant establishes to the satisfaction of the plan representative
        that the consent of the spouse cannot be obtained because there is no
        spouse or the spouse cannot be located. A spouse's consent under this
        paragraph shall not be valid with respect to any other spouse. A
        Participant may revoke a prior election without the consent of the
        spouse. Any new election will require a new spousal consent, unless the
        consent of the spouse expressly permits such election by the Participant
        without further consent by the spouse. A spouse's consent may be revoked
        at any time within the Participant's election period.

    (d) Special Rule for Profit Sharing Plan.  As provided in the preceding
        provisions of the Plan, if a Participant has a spouse to whom he has
        been continuously married throughout the one-year period ending on the
        date of his death, the Participant's Vested Account shall be paid to
        such spouse.  However, if there is no such spouse or if the surviving
        spouse has already consented in a manner conforming to the qualified
        election requirements in (c) above, the Vested Account shall be payable
        to the Participant's Beneficiary in the event of the Participant's
        death.

        The Participant may waive the spousal death benefit described above at
        any time provided that no such waiver shall be effective unless it
        satisfies the conditions of (c) above (other than the 

                                       52
<PAGE>
 
        notification requirement referred to therein) that would apply to the
        Participant's waiver of the Qualified Preretirement Survivor Annuity.

        Because this is a profit sharing plan which pays death benefits as
        described above, this subsection (d) applies if the following condition
        is met:  with respect to the Participant, this Plan is not a direct or
        indirect transferee after December 31, 1984, of a defined benefit plan,
        money purchase plan (including a target plan), stock bonus plan or
        profit sharing plan which is subject to the survivor annuity
        requirements of Code Section 401(a)(11) and Code Section 417.  If the
        above condition is met, spousal consent is not required for electing a
        benefit payable in a form that is not a life annuity.  If the above
        condition is not met, the consent requirements of this article shall be
        operative.

SECTION 6.04--NOTICE REQUIREMENTS.

    (a) Optional forms of retirement benefit.  The Plan Administrator shall
        furnish to the Participant and the Participant's spouse a written
        explanation of the optional forms of retirement benefit in the OPTIONAL
        FORMS OF DISTRIBUTION AND DISTRIBUTION REQUIREMENTS SECTION of Article
        VI, including the material features and relative values of these
        options, in a manner that would satisfy the notice requirements of Code
        Section 417(a)(3) and the right of the Participant and the Participant's
        spouse to defer distribution until the benefit is no longer immediately
        distributable.  The Plan Administrator shall furnish the written
        explanation by a method reasonably calculated to reach the attention of
        the Participant and the Participant's spouse no less than 30 days and no
        more than 90 days before the Annuity Starting Date.

    (b) Qualified Joint and Survivor Form.  The Plan Administrator shall furnish
        to the Participant a written explanation of the following:  the terms
        and conditions of the Qualified Joint and Survivor Form; the
        Participant's right to make, and the effect of, an election to waive the
        Qualified Joint and Survivor Form; the rights of the Participant's
        spouse; and the right to revoke an election and the effect of such a
        revocation.  The Plan Administrator shall furnish the written
        explanation by a method reasonably calculated to reach the attention of
        the Participant no less than 30 days and no more than 90 days before the
        Annuity Starting Date.

        After the written explanation is given, a Participant or spouse may
        make written request for additional information.  The written
        explanation must be personally delivered or mailed (first class mail,
        postage prepaid) to the Participant or spouse within 30 days from the
        date of the written request.  The Plan Administrator does not need to
        comply with more than one such request by a Participant or spouse.

        The Plan Administrator's explanation shall be written in nontechnical
        language and will explain the terms and conditions of the Qualified
        Joint and Survivor Form and the financial effect upon the Participant's
        benefit (in terms of dollars per benefit payment) of electing not to
        have benefits distributed in accordance with the Qualified Joint and
        Survivor Form.

    (c) Qualified Preretirement Survivor Annuity.  As required by the Code and
        Federal regulation, the Plan Administrator shall furnish to the
        Participant a written explanation of the following:  the terms and
        conditions of the Qualified Preretirement Survivor Annuity; the
        Participant's right to make, and the effect of, an election to waive the
        Qualified Preretirement Survivor Annuity; the rights of the
        Participant's spouse; and the right to revoke an election and the effect
        of such a revocation.  The Plan Administrator shall furnish the written
        explanation by a method reasonably calculated to 

                                       53
<PAGE>
 
        reach the attention of the Participant within the applicable period. The
        applicable period for a Participant is whichever of the following
        periods ends last:

        (1) the period beginning one year before the date the individual becomes
            a Participant and ending one year after such date; or

        (2) the period beginning one year before the date the Participant's
            spouse is first entitled to a Qualified Preretirement Survivor
            Annuity and ending one year after such date.

        If such notice is given before 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, an additional notice shall be given within
        such period.  If a Participant ceases to be an Employee before attaining
        age 35, an additional notice shall be given within the period beginning
        one year before the date he ceases to be an Employee and ending one year
        after such date.

        After the written explanation is given, a Participant or spouse may
        make written request for additional information.  The written
        explanation must be personally delivered or mailed (first class mail,
        postage prepaid) to the Participant or spouse within 30 days from the
        date of the written request.  The Plan Administrator does not need to
        comply with more than one such request by a Participant or spouse.

        The Plan Administrator's explanation shall be written in nontechnical
        language and will explain the terms and conditions of the Qualified
        Preretirement Survivor Annuity and the financial effect upon the
        spouse's benefit (in terms of dollars per benefit payment) of electing
        not to have benefits distributed in accordance with the Qualified
        Preretirement Survivor Annuity.

                              TERMINATION OF PLAN

    The Employer expects to continue the Plan indefinitely but reserves the
right to terminate the Plan in whole or in part at any time upon giving written
notice to all parties concerned.  Complete discontinuance of Contributions under
the Plan constitutes complete termination of Plan.

    The Account of each Participant shall be fully (100%) vested and
nonforfeitable as of the effective date of complete termination of Plan.  The
Account of each Participant who is included in the group of Participants deemed
to be affected by the partial termination of the Plan shall be fully (100%)
vested and nonforfeitable as of the effective date of the partial Plan
termination.  The Participant's Account shall continue to participate in the
earnings credited, expenses charged and any appreciation or depreciation of the
Investment Fund until the Vested Account is distributed.  A distribution under
this article will be a retirement benefit and shall be distributed to the
Participant according to the provisions of Article VI.

    A Participant's Account which does not result from Contributions which are
used to compute the Actual Deferral Percentage, as defined in the EXCESS AMOUNTS
SECTION of Article III, may be distributed to the Participant after the
effective date of the complete or partial Plan termination.  A Participant's
Account resulting from Contributions which are used to compute such percentage
may be distributed upon termination of the Plan without the establishment or
maintenance of another defined contribution plan, other than an employee stock
ownership plan (as defined in Code Section 4975(e) or Code Section 409) or a
simplified employee pension plan (as defined in Code Section 408(k)).  Such a
distribution made after March 31, 1988, must be in a single sum.

    Upon complete termination of Plan, no more Employees shall become
Participants and no more Contributions shall be made.

    The assets of this Plan shall not be paid to the Employer at any time,
except that, after the satisfaction of all liabilities under the Plan, any
assets remaining may be paid to the Employer.  The payment may not be made if it
would contravene any provision of law.

                                  ARTICLE VIII

                             ADMINISTRATION OF PLAN

SECTION 8.01--ADMINISTRATION.

    Subject to the provisions of this article, the Plan Administrator has
complete control of the administration of the Plan.  The Plan Administrator has
all the powers necessary for it to properly carry out its administrative duties.
Not in limitation, but in amplification of the foregoing, the Plan Administrator
has the power to construe the Plan, including ambiguous provisions, and to
determine all questions that may arise under the Plan, including all questions
relating to the eligibility of Employees to participate in the Plan and the
amount of benefit to which any Participant, Beneficiary, spouse or Contingent
Annuitant may become entitled.  The Plan Administrator's decisions upon all
matters within the scope of its authority shall be final.

    Unless otherwise set out in the Plan or Group Contract, the Plan
Administrator may delegate recordkeeping and other duties which are necessary
for the administration of the Plan to any person or firm which agrees to accept
such duties.  The Plan Administrator shall be entitled to rely upon all tables,
valuations, certificates and reports furnished by the consultant or actuary
appointed by the Plan Administrator and upon all opinions given by any counsel
selected or approved by the Plan Administrator.

    The Plan Administrator shall receive all claims for benefits by
Participants, former Participants, Beneficiaries, spouses, and Contingent
Annuitants.  The Plan Administrator shall determine all facts necessary to
establish the right of any Claimant to benefits and the amount of those benefits
under the provisions of the Plan.  The Plan Administrator may establish rules
and procedures to be followed by Claimants in filing claims for benefits, in
furnishing and verifying proofs necessary to determine age, and in any other
matters required to administer the Plan.

    Each Participant with an investment in the Qualifying Employer Securities
Fund, shall be entitled to direct the Trustee as to the exercise of all voting
powers over shares allocated to his Account provided that such Participant had
such an investment in his Account as of the most recent date coincident with or
preceding the applicable record date for which such records are available. The
Trustee shall vote all Qualifying Employer Securities allocated or unallocated
to a Participant's Qualifying Employer Securities Account which are not voted by
the Participant, because the Participant has not directed (or not timely
directed) the Trustee as to the manner in which such Qualifying Employer
Securities are to be voted, in the same proportion as those shares of Qualifying
Employer Securities for which the Trustee has received proper direction on such
matter.

    In the event that a tender offer is made for some or all of the shares of
the Employer, each Participant shall have the right to direct whether those
shares allocated to his Account, whether or not vested, shall be tendered.  This
right shall be exercised in the manner set forth herein.  In the absence of a
written directive from or election by a Participant to the Plan Administrator,
the Plan Administrator shall direct the Trustee not to tender such shares.
Because the choice is to be given to the Participants, the Plan Administrator
and the Trustee shall not have fiduciary responsibility with respect to the
decision to tender or not or whether to tender all such shares or only a portion
thereof.

    In order to facilitate the decision of Participants whether to tender their
shares in a tender offer (or how many shares to tender), the Plan Administrator
shall provide election forms for the Participants, whereby they may elect to
tender or not and whereby they may elect to tender all or a portion of such
shares.  Unless otherwise limited by Federal securities law, such election may
be made or changed at any time prior to the date 

                                       56
<PAGE>
 
before the expiration date of the tender offer (with extensions); any election
or change in election must be received by the Plan Administrator, or designated
representative of the Plan Administrator, on or before the day preceding the
expiration date of the tender offer (with extensions, if any). The Plan
Administrator may develop procedures to facilitate Participants' choices, such
as the use of facsimile transmissions for the Employees located in areas
physically remote from the Plan Administrator. The election shall be binding on
the Plan Administrator and the Trustee. The Plan Administrator shall make every
effort to distribute the notice of the tender, election forms and other
communications related to the tender offer to all Participants as soon as
practicable following the announcement of the tender offer, including mailing
such notice and form to Participants and posting such notice in places designed
to be reviewed by Participants.

    As to shares which are not allocated to the Account of any Participant, all
such shares (in the aggregate) shall be tendered or not as the majority of the
shares held by Participants and directed by Participants are tendered or not.
The Plan Administrator shall direct the Trustee to tender all such unallocated
shares or not, in accordance with the elections of the Participants having an
allocation of the majority of the shares under the Plan.

Fractional Shares.  After the expiration of the period during which Participants
may direct the Trustee to tender their shares, the Trustee shall determine the
total number of whole shares it was directed to tender, and the total number of
whole shares it was directed not to tender (either expressly or by a
Participant's failure to timely to respond).  If the majority of the allocated
and unallocated whole shares of Qualifying Employer Securities were directed to
be tendered, then the Trustee also shall tender, as promptly as practical, any
allocated or unallocated fractional shares that are held in the Plan.  However,
if the majority of the allocated or unallocated whole shares of Qualifying
Employer Securities were directed not to be tendered (either expressly or by a
Participant's failure timely to respond), the Trustee shall not tender such
shares.

    In voting or tendering shares of Qualifying Employer Securities under this
section, the Trustee is directed and agrees to follow the instructions of the
Participants (or beneficiaries) as named fiduciaries in accordance with ERISA
Section 403(a)(1).

    i)  Each Participant's (or beneficiary's) voting or tendering instructions
        under this section will be completely confidential. The Trustee or his
        agent agrees to hold such instructions in confidence and not to divulge
        or release such instructions to any person, including particularly any
        employer, officer, employer or director of an employer, or any person
        directly or indirectly controlling, controlled by or under common
        control with an employer (including any such person which is also a
        Trustee); provided, however, that to the extent necessary to the
        operation of the plan and the implementation of Participants' voting or
        tendering rights, the Trustee may transmit such instructions to a
        recordkeeper, auditor, tallier or similar service provider who is not a
        person specified in the preceding clause of this sentence and who agrees
        not to divulge or release such instructions to any such person.

    ii) Any of the Trustee's duties under this section may be performed by an
        agent of the Trustee or by a service provider retained by the Trustee,
        the Plan Administrator or the Employer.

SECTION 8.02--RECORDS.

    All acts and determinations of the Plan Administrator shall be duly
recorded.  All these records, together with other documents necessary for the
administration of the Plan, shall be preserved in the Plan Administrator's
custody.

                                       57
<PAGE>
 
    Writing (handwriting, typing, printing), photostating, photographing,
microfilming, magnetic impulse, mechanical or electrical recording or other
forms of data compilation shall be acceptable means of keeping records.

SECTION 8.03--INFORMATION AVAILABLE.

    Any Participant in the Plan or any Beneficiary may examine copies of the
Plan description, latest annual report, any bargaining agreement, this Plan, the
Group Contract or any other instrument under which the Plan was established or
is operated.  The Plan Administrator shall maintain all of the items listed in
this section in its office, or in such other place or places as it may designate
in order to comply with governmental regulations.  These items may be examined
during reasonable business hours.  Upon the written request of a Participant or
Beneficiary receiving benefits under the Plan, the Plan Administrator will
furnish him with a copy of any of these items.  The Plan Administrator may make
a reasonable charge to the requesting person for the copy.

SECTION 8.04--CLAIM AND APPEAL PROCEDURES.

    A Claimant must submit any required forms and pertinent information when
making a claim for benefits under the Plan.

    If a claim for benefits under the Plan is denied, the Plan Administrator
shall provide adequate written notice to the Claimant whose claim for benefits
under the Plan has been denied.  The notice must be furnished within 90 days of
the date that the claim is received by the Plan Administrator.  The Claimant
shall be notified in writing within this initial 90-day period if special
circumstances require an extension of time needed to process the claim and the
date by which the Plan Administrator's decision is expected to be rendered.  The
written notice shall be furnished no later than 180 days after the date the
claim was received by the Plan Administrator.

    The Plan Administrator's notice to the Claimant shall specify the reason for
the denial; specify references to pertinent Plan provisions on which denial is
based; describe any additional material and information needed for the Claimant
to perfect his claim for benefits; explain why the material and information is
needed; inform the Claimant that any appeal he wishes to make must be in writing
to the Plan Administrator within 60 days after receipt of the Plan
Administrator's notice of denial of benefits and that failure to make the
written appeal within such 60-day period shall render the Plan Administrator's
determination of such denial final, binding and conclusive.

    If the Claimant appeals to the Plan Administrator, the Claimant, or his
authorized representative, may submit in writing whatever issues and comments
the Claimant, or his representative, feels are pertinent.  The Claimant, or his
authorized representative may review pertinent Plan documents.  The Plan
Administrator shall reexamine all facts related to the appeal and make a final
determination as to whether the denial of benefits is justified under the
circumstances.  The Plan Administrator shall advise the Claimant of its decision
within 60 days of his written request for review, unless special circumstances
(such as a hearing) would make rendering a decision within the 60-day limit
unfeasible.  The Claimant must be notified within the 60-day limit if an
extension is necessary.  The Plan Administrator shall render a decision on a
claim for benefits no later than 120 days after the request for review is
received.

SECTION 8.05--UNCLAIMED VESTED ACCOUNT PROCEDURE.

    At the time the Participant's Vested Account is distributable to the
Participant, spouse or Beneficiary without his consent according to the
provisions of Article VI or Article IX, the Plan Administrator, by certified or

                                       58
<PAGE>
 
registered mail addressed to his last known address and in accordance with the
notice requirements of Article VI, will notify him of his entitlement to a
benefit.  If the Participant, spouse or Beneficiary fails to claim the Vested
Account or make his whereabouts known in writing within six months from the date
of mailing the notice, the Plan Administrator may treat such unclaimed Vested
Account as a forfeiture and apply it according to the forfeiture provisions of
Article III.  If Article III contains no forfeiture provisions, such amount will
be applied to reduce the earliest Employer Contributions due after the
forfeiture arises.

    If a Participant's Vested Account is forfeited according to the provisions
of the above paragraph and the Participant, his spouse or his Beneficiary at any
time make a claim for benefits, the forfeited Vested Account shall be
reinstated, unadjusted for any gains or losses occurring after the date it was
forfeited.  The reinstated Vested Account shall then be distributed to the
Participant, spouse or Beneficiary according to the preceding provisions of the
Plan.

SECTION 8.06--DELEGATION OF AUTHORITY.

    All or any part of the administrative duties and responsibilities under this
article may be delegated by the Plan Administrator to a retirement committee.
The duties and responsibilities of the retirement committee shall be set out in
a separate written agreement.

                                       59

                                   ARTICLE IX

                               GENERAL PROVISIONS

SECTION 9.01--AMENDMENTS.

    The Employer may amend this Plan at any time, including any remedial
retroactive changes (within the specified period of time as may be determined by
Internal Revenue Service regulations) to comply with the requirements of any law
or regulation issued by any governmental agency to which the Employer is
subject.  An amendment may not diminish or adversely affect any accrued interest
or benefit of Participants or their Beneficiaries or eliminate an optional form
of distribution with respect to benefits attributable to service before the
amendment nor allow reversion or diversion of Plan assets to the Employer at any
time, except as may be necessary to comply with the requirements of any law or
regulation issued by any governmental agency to which the Employer is subject.
No amendment to this Plan shall be effective to the extent that it has the
effect of decreasing a Participant's accrued benefit.  However, a Participant's
Account may be reduced to the extent permitted under Code Section 412(c)(8).
For purposes of this paragraph, a Plan amendment which has the effect of
decreasing a Participant's Account or eliminating an optional form of benefit,
with respect to benefits attributable to service before the amendment shall be
treated as reducing an accrued benefit.  Furthermore, if the vesting schedule of
the Plan is amended, in the case of an Employee who is a Participant as of the
later of the date such amendment is adopted or the date it becomes effective,
the nonforfeitable percentage (determined as of such date) of such Employee's
employer-derived accrued benefit will not be less than his percentage computed
under the Plan without regard to such amendment.

    An amendment shall not decrease a Participant's vested interest in the Plan.
If an amendment to the Plan, or a deemed amendment in the case of a change in
top-heavy status of the Plan as provided in the MODIFICATION OF VESTING
REQUIREMENTS SECTION of Article X, changes the computation of the percentage
used to determine that portion of a Participant's Account attributable to
Employer Contributions which is nonforfeitable (whether directly or indirectly),
each Participant or former Participant

    (a) who has completed at least three Years of Service on the date the
        election period described below ends (five Years of Service if the
        Participant does not have at least one Hour-of-Service in a Plan Year
        beginning after December 31, 1988) and

    (b) whose nonforfeitable percentage will be determined on any date after the
        date of the change

may elect, during the election period, to have the nonforfeitable percentage of
his Account that results from Employer Contributions determined without regard
to the amendment.  This election may not be revoked.  An election does not need
to be provided for any Participant or former Participant whose nonforfeitable
percentage, determined according to the Plan provisions as changed, cannot at
any time be less than the percentage determined without regard to such change.
The election period shall begin no later than the date the Plan amendment is
adopted, or deemed adopted in the case of a change in the top-heavy status of
the Plan, and end no earlier than the sixtieth day after the latest of the date
the amendment is adopted (deemed adopted) or becomes effective, or the date the
Participant is issued written notice of the amendment (deemed amendment) by the
Employer or the Plan Administrator.

                                       60
<PAGE>
 
SECTION 9.02--DIRECT ROLLOVERS.

    This section applies to distributions made on or after January 1, 1993.
Notwithstanding any provision of the Plan to the contrary that would otherwise
limit a Distributee's election under this section, 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.

SECTION 9.03--MERGERS AND DIRECT TRANSFERS.

    The Plan may not be merged or consolidated with, nor have its assets or
liabilities transferred to, any other retirement plan, unless each Participant
in the plan would (if the plan then terminated) receive a benefit immediately
after the merger, consolidation or transfer which is equal to or greater than
the benefit the Participant would have been entitled to receive immediately
before the merger, consolidation or transfer (if this Plan had then terminated).
The Employer may enter into merger agreements or direct transfer of assets
agreements with the employers under other retirement plans which are qualifiable
under Code Section 401(a), including an elective transfer, and may accept the
direct transfer of plan assets, or may transfer plan assets, as a party to any
such agreement.  The Employer shall not consent to, or be a party to a merger,
consolidation or transfer of assets with a defined benefit plan if such action
would result in a defined benefit feature being maintained under this Plan.

    The Plan may accept a direct transfer of plan assets on behalf of an
Eligible Employee.  If the Eligible Employee is not an Active Participant when
the transfer is made, the Eligible Employee shall be deemed to be an Active
Participant only for the purpose of investment and distribution of the
transferred assets.  Employer Contributions shall not be made for or allocated
to the Eligible Employee, until the time he meets all of the requirements to
become an Active Participant.

    The Plan shall hold, administer and distribute the transferred assets as a
part of the Plan.  The Plan shall maintain a separate account for the benefit of
the Employee on whose behalf the Plan accepted the transfer in order to reflect
the value of the transferred assets.  Unless a transfer of assets to the Plan is
an elective transfer, the Plan shall apply the optional forms of benefit
protections described in the AMENDMENTS SECTION of Article IX to all transferred
assets.  A transfer is elective if:  (1) the transfer is voluntary, under a
fully informed election by the Participant; (2) the Participant has an
alternative that retains his Code Section 411(d)(6) protected benefits
(including an option to leave his benefit in the transferor plan, if that plan
is not terminating); (3) if the transferor plan is subject to Code Sections
401(a)(11) and 417, the transfer satisfies the applicable spousal consent
requirements of the Code; (4) the notice requirements under Code Section 417,
requiring a written explanation with respect to an election not to receive
benefits in the form of a qualified joint and survivor annuity, are met with
respect to the Participant and spousal transfer election; (5) the Participant
has a right to immediate distribution from the transferor plan under provisions
in the plan not inconsistent with Code Section 401(a); (6) the transferred
benefit is equal to the Participant's entire nonforfeitable accrued benefit
under the transferor plan, calculated to be at least the greater of the single
sum distribution provided by the transferor plan (if any) or the present value
of the Participant's accrued benefit under the transferor plan payable at the
plan's normal retirement age and calculated using an interest rate subject to
the restrictions of Code Section 417(e) and subject to the overall limitations
of Code Section 415; (7) the Participant has a 100% nonforfeitable interest in
the transferred benefit; and (8) the transfer otherwise satisfies applicable
Treasury regulations.

<PAGE>
 
SECTION 9.04--PROVISIONS RELATING TO THE INSURER
              AND OTHER PARTIES.

    The obligations of an Insurer shall be governed solely by the provisions of
the Group Contract.  The Insurer shall not be required to perform any act not
provided in or contrary to the provisions of the Group Contract.  See the
CONSTRUCTION SECTION of this article.

    Any issuer or distributor of investment contracts or securities is governed
solely by the terms of its policies, written investment contract, prospectuses,
security instruments, and any other written agreements entered into with the
Trustee.

    Such Insurer, issuer or distributor is not a party to the Plan, nor bound in
any way by the Plan provisions.  Such parties shall not be required to look to
the terms of this Plan, nor to determine whether the Employer, the Plan
Administrator, the Trustee, or the Named Fiduciary have the authority to act in
any particular manner or to make any contract or agreement.

    Until notice of any amendment or termination of this Plan or a change in
Trustee has been received by the Insurer at its home office or an issuer or
distributor at their principal address, they are and shall be fully protected in
assuming that the Plan has not been amended or terminated and in dealing with
any party acting as Trustee according to the latest information which they have
received at their home office or principal address.

SECTION 9.05--EMPLOYMENT STATUS.

    Nothing contained in this Plan gives an Employee the right to be retained in
the Employer's employ or to interfere with the Employer's right to discharge any
Employee.

SECTION 9.06--RIGHTS TO PLAN ASSETS.

    No Employee shall have any right to or interest in any assets of the Plan
upon termination of his employment or otherwise except as specifically provided
under this Plan, and then only to the extent of the benefits payable to such
Employee in accordance with Plan provisions.

    Any final payment or distribution to a Participant or his legal
representative or to any Beneficiaries, spouse or Contingent Annuitant of such
Participant under the Plan provisions shall be in full satisfaction of all
claims against the Plan, the Named Fiduciary, the Plan Administrator, the
Trustee, the Insurer, and the Employer arising under or by virtue of the Plan.

SECTION 9.07--BENEFICIARY.

    Each Participant may name a Beneficiary to receive any death benefit (other
than any income payable to a Contingent Annuitant) that may arise out of his
participation in the Plan.  The Participant may change his Beneficiary from time
to time.  Unless a qualified election has been made, for purposes of
distributing any death benefits before Retirement Date, the Beneficiary of a
Participant who has a spouse who is entitled to a Qualified Preretirement
Survivor Annuity shall be the Participant's spouse.  The Participant's
Beneficiary designation and any change of Beneficiary shall be subject to the
provisions of the ELECTION PROCEDURES SECTION of Article VI.  It is the
responsibility of the Participant to give written notice to the Insurer of the
name of the Beneficiary on a form furnished for that purpose.

                                       62
<PAGE>
 
    With the Employer's consent, the Plan Administrator may maintain records of
Beneficiary designations for Participants before their Retirement Dates.  In
that event, the written designations made by Participants shall be filed with
the Plan Administrator.  If a Participant dies before his Retirement Date, the
Plan Administrator shall certify to the Insurer the Beneficiary designation on
its records for the Participant.

    If, at the death of a Participant, there is no Beneficiary named or
surviving, any death benefit under the Group Contract shall be paid under the
applicable provisions of the Group Contract.

SECTION 9.08--NONALIENATION OF BENEFITS.

    Benefits payable under the Plan are not subject to the claims of any
creditor of any Participant, Beneficiary, spouse or Contingent Annuitant.  A
Participant, Beneficiary, spouse or Contingent Annuitant does not have any
rights to alienate, anticipate, commute, pledge, encumber or assign any of such
benefits, except in the case of a loan as provided in the LOANS TO PARTICIPANTS
SECTION of Article V.  The preceding sentences shall also apply to the creation,
assignment, or recognition of a right to any benefit payable with respect to a
Participant according to a domestic relations order, unless such order is
determined by the Plan Administrator to be a qualified domestic relations order,
as defined in Code Section 414(p), or any domestic relations order entered
before January 1, 1985.

SECTION 9.09--CONSTRUCTION.

    The validity of the Plan or any of its provisions is determined under and
construed according to Federal law and, to the extent permissible, according to
the laws of the state in which the Employer has its principal office.  In case
any provision of this Plan is held illegal or invalid for any reason, such
determination shall not affect the remaining provisions of this Plan, and the
Plan shall be construed and enforced as if the illegal or invalid provision had
never been included.

    In the event of any conflict between the provisions of the Plan and the
terms of any contract or policy issued hereunder, the provisions of the Plan
control the operation and administration of the Plan.

SECTION 9.10--LEGAL ACTIONS.

    The Plan, the Plan Administrator, the Trustee and the Named Fiduciary are
the necessary parties to any action or proceeding involving the assets held with
respect to the Plan or administration of the Plan or Trust.  No person employed
by the Employer, no Participant, former Participant or their Beneficiaries or
any other person having or claiming to have an interest in the Plan is entitled
to any notice of process.  A final judgment entered in any such action or
proceeding shall be binding and conclusive on all persons having or claiming to
have an interest in the Plan.

SECTION 9.11--SMALL AMOUNTS.

    If the Vested Account of a Participant has never exceeded $3,500, the entire
Vested Account shall be payable in a single sum as of the earliest of his
Retirement Date, the date he dies, or the date he ceases to be an Employee for
any other reason.  This is a small amounts payment.  If a small amount is
payable as of the date the Participant dies, the small amounts payment shall be
made to the Participant's Beneficiary (spouse if the death benefit is payable to
the spouse).  If a small amount is payable while the Participant is living, the
small amounts payment shall be made to the Participant.  The small amounts
payment is in full settlement of all benefits otherwise payable.

                                       63
<PAGE>
 
    No other small amounts payments shall be made.

SECTION 9.12--WORD USAGE.

    The masculine gender, where used in this Plan, shall include the feminine
gender and the singular words as used in this Plan may include the plural,
unless the context indicates otherwise.

SECTION 9.13--TRANSFERS BETWEEN PLANS.

    If an Employee previously participated in another plan of the Employer which
credited service under the elapsed time method for any purpose which under this
Plan is determined using the hours method, then the Employee's service shall be
equal to the sum of (a), (b) and (c) below:

    (a) The number of whole years of service credited to him under the other
        plan as of the date he became an Eligible Employee under this Plan.

    (b) One year or a part of a year of service for the applicable service
        period in which he became an Eligible Employee if he is credited with
        the required number of Hours-of-Service.  If the Employer does not have
        sufficient records to determine the Employee's actual Hours-of-Service
        in that part of the service period before the date he became an Eligible
        Employee, the Hours-of-Service shall be determined using an equivalency.
        For any month in which he would be required to be credited with one
        Hour-of-Service, the Employee shall be deemed for purposes of this
        section to be credited with 190 Hours-of-Service.

    (c) The Employee's service determined under this Plan using the hours method
        after the end of the applicable service period in which he became an
        Eligible Employee.

    If an Employee previously participated in another plan of the Employer which
credited service under the hours method for any purpose which under this Plan is
determined using the elapsed time method, then the Employee's service shall be
equal to the sum of (d), (e) and (f) below:

    (d) The number of whole years of service credited to him under the other
        plan as of the beginning of the applicable service period under that
        plan in which he became an Eligible Employee under this Plan.

    (e) The greater of (1) the service that would be credited to him for that
        entire service period using the elapsed time method or (2) the service
        credited to him under the other plan as of the date he became an
        Eligible Employee under this Plan.

    (f) The Employee's service determined under this Plan using the elapsed time
        method after the end of the applicable service period under the other
        plan in which he became an Eligible Employee.

    Any modification of service contained in this Plan shall be applicable to
the service determined pursuant to this section.

    If the Employee previously participated in the plan of a Controlled Group
member which credited service under a different method than is used in this
Plan, for purposes of determining eligibility and vesting the provisions above
shall apply as though the plan of the Controlled Group member were a plan of the
Employer.

                          TOP-HEAVY PLAN REQUIREMENTS

SECTION 10.01--APPLICATION.

    The provisions of this article shall supersede all other provisions in the
Plan to the contrary.

    For the purpose of applying the Top-heavy Plan requirements of this article,
all members of the Controlled Group shall be treated as one Employer.  The term
Employer as used in this article shall be deemed to include all members of the
Controlled Group unless the term as used clearly indicates only the Employer is
meant.

    The accrued benefit or account of a participant which results from
deductible voluntary contributions shall not be included for any purpose under
this article.

    The minimum vesting and contribution provisions of the MODIFICATION OF
VESTING REQUIREMENTS and MODIFICATION OF CONTRIBUTIONS SECTIONS of Article X
shall not apply to any Employee who is included in a group of Employees covered
by a collective bargaining agreement which the Secretary of Labor finds to be a
collective bargaining agreement between employee representatives and one or more
employers, including the Employer, if there is evidence that retirement benefits
were the subject of good faith bargaining between such representatives.  For
this purpose, the term "employee representatives" does not include any
organization more than half of whose members are employees who are owners,
officers, or executives.

SECTION 10.02--DEFINITIONS.

    The following terms are defined for purposes of this article.

    Aggregation Group means

    (a) each of the Employer's retirement plans in which a Key Employee is a
        participant during the Year containing the Determination Date or one of
        the four preceding Years,

    (b) each of the Employer's other retirement plans which allows the plan(s)
        described in (a) above to meet the nondiscrimination requirement of Code
        Section 401(a)(4) or the minimum coverage requirement of Code Section
        410, and

    (c) any of the Employer's other retirement plans not included in (a) or (b)
        above which the Employer desires to include as part of the Aggregation
        Group.  Such a retirement plan shall be included only if the Aggregation
        Group would continue to satisfy the requirements of Code Section
        401(a)(4) and Code Section 410.

    The plans in (a) and (b) above constitute the "required" Aggregation Group.
    The plans in (a), (b) and (c) above constitute the "permissive" Aggregation
    Group.

    Compensation means, as to an Employee for any period, compensation as
    defined in the CONTRIBUTION LIMITATION SECTION of Article III.  For purposes
    of determining who is a Key Employee, Compensation shall include, in
    addition to compensation as defined in the CONTRIBUTION LIMITATION SECTION
    of 

                                       65
<PAGE>
 
    Article III, elective contributions. Elective contributions are amounts
    excludable from the Employee's gross income under Code Sections 125,
    402(e)(3), 402(h) or 403(b), and contributed by the Employer, at the
    Employee's election, to a Code Section 401(k) arrangement, a simplified
    employee pension, cafeteria plan or tax-sheltered annuity.

    For purposes of Compensation as defined in this section, Compensation shall
    be limited to the maximum dollar amount, as adjusted, in the same manner and
    in the same time as the Compensation defined in the DEFINITION SECTION of
    Article I.

    Determination Date means as to this Plan for any Year, the last day of the
    preceding Year.  However, if there is no preceding Year, the Determination
    Date is the last day of such Year.

    Key Employee means any Employee or former Employee (including Beneficiaries
    of deceased Employees) who at any time during the determination period was

    (a) one of the Employer's officers (subject to the maximum below) whose
        Compensation (as defined in this section) for the Year exceeds 50
        percent of the dollar limitation under Code Section 415(b)(1)(A),

    (b) one of the ten Employees who owns (or is considered to own, under Code
        Section 318) more than a half percent ownership interest and one of the
        largest interests in the Employer during any Year of the determination
        period if such person's Compensation (as defined in this section) for
        the Year exceeds the dollar limitation under Code Section 415(c)(1)(A),

    (c) a five-percent owner of the Employer, or

    (d) a one-percent owner of the Employer whose Compensation (as defined in
        this section) for the Year is more than $150,000.

    Each member of the Controlled Group shall be treated as a separate employer
    for purposes of determining ownership in the Employer.

    The determination period is the Year containing the Determination Date and
    the four preceding Years.  If the Employer has fewer than 30 Employees, no
    more than three Employees shall be treated as Key Employees because they are
    officers.  If the Employer has between 30 and 500 Employees, no more than
    ten percent of the Employer's Employees (if not an integer, increased to the
    next integer) shall be treated as Key Employees because they are officers.
    In no event will more than 50 Employees be treated as Key Employees because
    they are officers if the Employer has 500 or more Employees.  The number of
    Employees for any Plan Year is the greatest number of Employees during the
    determination period.  Officers who are employees described in Code Section
    414(q)(8) shall be excluded.  If the Employer has more than the maximum
    number of officers to be treated as Key Employees, the officers shall be
    ranked by amount of annual Compensation (as defined in this section), and
    those with the greater amount of annual Compensation during the
    determination period shall be treated as Key Employees.  To determine the
    ten Employees owning the largest interests in the Employer, if more than one
    Employee has the same ownership interest, the Employee(s) having the greater
    annual Compensation shall be treated as owning the larger interest(s).  The
    determination of who is a Key Employee shall be made according to Code
    Section 416(i)(1) and the regulations thereunder.

                                       66
<PAGE>
 
    Non-key Employee means a person who is a non-key employee within the meaning
    of Code Section 416 and regulations thereunder.

    Present Value means the present value of a participant's accrued benefit
    under a defined benefit plan as of his normal retirement age (attained age
    if later) or, if the plan provides non-proportional subsidies, the age at
    which the benefit is most valuable.  The accrued benefit of any Employee
    (other than a Key Employee) shall be determined under the method which is
    used for accrual purposes for all plans of the Employer or if there is no
    one method which is used for accrual purposes for all plans of the Employer,
    as if such benefit accrued not more rapidly than the slowest accrual rate
    permitted under Code Section 411(b)(1)(C).  For purposes of establishing
    Present Value, any benefit shall be discounted only for 7.5% interest and
    mortality according to the 1971 Group Annuity Table (Male) without the 7%
    margin but with projection by Scale E from 1971 to the later of (a) 1974, or
    (b) the year determined by adding the age to 1920, and wherein for females
    the male age six years younger is used.  If the Present Value of accrued
    benefits is determined for a participant under more than one defined benefit
    plan included in the Aggregation Group, all such plans shall use the same
    actuarial assumptions to determine the Present Value.

    Top-heavy Plan means a plan which is a top-heavy plan for any plan year
    beginning after December 31, 1983.  This Plan shall be a Top-heavy Plan if

    (a) the Top-heavy Ratio for this Plan alone exceeds 60 percent and this Plan
        is not part of any required Aggregation Group or permissive Aggregation
        Group.

    (b) this Plan is a part of a required Aggregation Group, but not part of a
        permissive Aggregation Group, and the Top-heavy Ratio for the required
        Aggregation Group exceeds 60 percent.

    (c) this Plan is a part of a required Aggregation Group and part of a
        permissive Aggregation Group and the Top-heavy Ratio for the permissive
        Aggregation Group exceeds 60 percent.

    Top-heavy Ratio means the ratio calculated below for this Plan or for the
    Aggregation Group.

    (a) 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 five-year
        period ending on the determination date 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 and the denominator of which is the sum of all
        account balances of all employees as of the determination date.  Both
        the numerator and denominator of the Top-heavy Ratio are adjusted for
        any distribution of an account balance (including those made from
        terminated plan(s) of the Employer which would have been part of the
        required Aggregation Group had such plan(s) not been terminated) made in
        the five-year period ending on the determination date.  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.

    (b) 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 five-year period ending on the determination date has or has
        had accrued benefits, the Top-heavy Ratio for any required or permissive
        Aggregation Group as appropriate is a 

                                       67
<PAGE>
 
        fraction, the numerator of which is the sum of the account balances
        under the defined contribution plan(s) of all Key Employees and the
        Present Value of accrued benefits under the defined benefit plan(s) for
        all Key Employees, and the denominator of which is the sum of the
        account balances under the defined contribution plan(s) for all
        employees and the Present Value of accrued benefits under the defined
        benefit plans for all employees. Both the numerator and denominator of
        the Top-heavy Ratio are adjusted for any distribution of an account
        balance or an accrued benefit (including those made from terminated
        plan(s) of the Employer which would have been part of the required
        Aggregation Group had such plan(s) not been terminated) made in the 
        five-year period ending on the determination date.

    (c) For purposes of (a) and (b) above, the value of account balances and the
        Present Value of accrued benefits 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 an
        employee who is not a Key Employee but who was a Key Employee in a prior
        year will be disregarded.  The calculation of the Top-heavy Ratio and
        the extent to which distributions, rollovers and transfers during the
        five-year period ending on the determination date are to be taken into
        account, shall be determined according to the provisions of Code Section
        416 and regulations thereunder.  The account balances and accrued
        benefits of an individual who has performed no service for the Employer
        during the five-year period ending on the determination date shall be
        excluded from the Top-heavy Ratio until the time the individual again
        performs service for the Employer.  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.

    Account, as used in this definition, means the value of an employee's
    account under one of the Employer's retirement plans on the latest valuation
    date.  In the case of a money purchase plan or target benefit plan, such
    value shall be adjusted to include any contributions made for or by the
    employee after the valuation date and on or before such determination date
    or due to be made as of such determination date but not yet forwarded to the
    insurer or trustee.  In the case of a profit sharing plan, such value shall
    be adjusted to include any contributions made for or by the employee after
    the valuation date and on or before such determination date.  During the
    first Year of any profit sharing plan such adjustment in value shall include
    contributions made after such determination date that are allocated as of a
    date in such Year.  The nondeductible employee contributions which an
    employee makes under a defined benefit plan of the Employer shall be treated
    as if they were contributions under a separate defined contribution plan.

    Valuation Date means, as to this Plan, the last day of the last calendar
    month ending in a Year.

    Year means the Plan Year unless another year is specified by the Employer in
    a separate written resolution in accordance with regulations issued by the
    Secretary of the Treasury or his delegate.

SECTION 10.03--MODIFICATION OF VESTING REQUIREMENTS.

    If a Participant's Vesting Percentage determined under Article I is not at
least as great as his Vesting Percentage would be if it were determined under a
schedule permitted in Code Section 416, the following shall apply.  During any
Year in which the Plan is a Top-heavy Plan, the Participant's Vesting Percentage
shall be the greater of the Vesting Percentage determined under Article I or the
schedule below.

                                       68
<PAGE>
 
         VESTING SERVICE                  NONFORFEITABLE
          (whole years)                     PERCENTAGE
 
           Less than 2                          0
                2                              20
                3                              40
                4                              60
                5                              80
            6 or more                         100

    The schedule above shall not apply to Participants who are not credited with
an Hour-of-Service after the Plan first becomes a Top-heavy Plan.  The Vesting
Percentage determined above applies to all of the Participant's Account
resulting from Employer Contributions, including Contributions the Employer
makes before the TEFRA Compliance Date or when the Plan is not a Top-heavy Plan.

    If, in a later Year, this Plan is not a Top-heavy Plan, a Participant's
Vesting Percentage shall be determined under Article I.  A Participant's Vesting
Percentage determined under either Article I or the schedule above shall never
be reduced and the election procedures of the AMENDMENTS SECTION of Article IX
shall apply when changing to or from the schedule as though the automatic change
were the result of an amendment.

    The part of the Participant's Vested Account resulting from the minimum
contributions required pursuant to the MODIFICATION OF CONTRIBUTIONS SECTION of
Article X shall not be forfeited because of a period of reemployment after
benefit payments have begun.

SECTION 10.04--MODIFICATION OF CONTRIBUTIONS.

    During any Year in which this Plan is a Top-heavy Plan, the Employer shall
make a minimum contribution or allocation on the last day of the Year for each
person who is a Non-key Employee on that day and who either was or could have
been an Active Participant during the Year.  A Non-key Employee is not required
to have a minimum number of hours-of-service or minimum amount of Compensation,
or to have had any Elective Deferral Contributions made for him in order to be
entitled to this minimum.  The minimum contribution or allocation for such
person shall be equal to the lesser of (a) or (b) below:

    (a) Three percent of such person's Compensation (as defined in this
        article).

    (b) The "highest percentage" of Compensation (as defined in this article)
        for such Year at which the Employer's contributions are made for or
        allocated to any Key Employee.  The highest percentage shall be
        determined by dividing the Employer Contributions made for or allocated
        to each Key Employee during such Year by the amount of his Compensation
        (as defined in this article), which is not more than the maximum set out
        above, and selecting the greatest quotient (expressed as a percentage).
        To determine the highest percentage, all of the Employer's defined
        contribution plans within the Aggregation Group shall be treated as one
        plan.  The provisions of this paragraph shall not apply if this Plan and
        a defined benefit plan of the Employer are required to be included in
        the Aggregation Group and this Plan enables the defined benefit plan to
        meet the requirements of Code Section 401(a)(4) or Code Section 410.

    If the Employer's contributions and allocations otherwise required under the
defined contribution plan(s) are at least equal to the minimum above, no
additional contribution or reallocation shall be required.  If the

                                       69
<PAGE>
 
Employer's contributions and allocations are less than the minimum above and
Employer Contributions under this Plan are allocated to Participants, any
Employer Contributions (other than those which are allocated on the basis of the
amount made for such person) shall be reallocated to provide the minimum. The
remaining Contributions shall be allocated as provided in the preceding articles
of this Plan taking into account any amount which was reallocated to provide the
minimum. If the Employer's total contributions and allocations are less than the
minimum above after any reallocation provided above, the Employer shall
contribute the difference for the Year.

    The minimum contribution or allocation applies to all of the Employer's
defined contribution plans in the aggregate which are Top-heavy Plans.  If an
additional contribution or allocation is required to meet the minimum above, it
shall be provided in this Plan.

    A minimum allocation under a profit sharing plan shall be made without
regard to whether or not the Employer has profits.

    If a person who is otherwise entitled to a minimum contribution or
allocation above is also covered under a defined benefit plan of the Employer's
which is a Top-heavy Plan during that same Year, the minimum benefits for him
shall not be duplicated.  The defined benefit plan shall provide an annual
benefit for him on, or adjusted to, a straight life basis of the lesser of (c)
two percent of his average pay multiplied by his years of service or (d) twenty
percent of his average pay.  Average pay and years of service shall have the
meaning set forth in such defined benefit plan for this purpose.

    For purposes of this section, any employer contribution made according to a
salary reduction or similar arrangement shall not apply before the first Yearly
Date in 1985.  On and after the first Yearly Date in 1989, any such employer
contributions and employer contributions which are matching contributions, as
defined in Code Section 401(m), shall not apply in determining if the minimum
contribution requirement has been met, but shall apply in determining the
minimum contribution required.  Forfeitures credited to a Participant's Account
are treated as employer contributions.

    The requirements of this section shall be met without regard to
contributions under Chapter 2 of the Code (relating to tax on self-employment),
Chapter 21 of the Code (relating to Federal Insurance Contributions Act), Title
II of the Social Security Act or any other Federal or state law.

SECTION 10.05--MODIFICATION OF CONTRIBUTION LIMITATION.

    If the provisions of subsection (e) of the CONTRIBUTION LIMITATION SECTION
of Article III are applicable for any Limitation Year during which this Plan is
a Top-heavy Plan, the benefit limitations shall be modified.  The definitions of
Defined Benefit Plan Fraction and Defined Contribution Plan Fraction in the
CONTRIBUTION LIMITATION SECTION of Article III shall be modified by substituting
"1.0" in lieu of "1.25."  The optional denominator for determining the Defined
Contribution Plan Fraction shall be modified by substituting "$41,500" in lieu
of "$51,875."  In addition, an adjustment shall be made to the numerator of the
Defined Contribution Plan Fraction.  The adjustment is a reduction of that
numerator similar to the modification of the Defined Contribution Plan Fraction
described in the CONTRIBUTION LIMITATION SECTION of Article III, and shall be
made with respect to the last Plan Year beginning before January 1, 1984.

    The modifications in the paragraph above shall not apply with respect to a
Participant so long as employer contributions, forfeitures or nondeductible
employee contributions are not credited to his account under this or any of the
Employer's other defined contribution plans and benefits do not accrue for such

                                       70
<PAGE>
 
Participant under the Employer's defined benefit plan(s), until the sum of his
Defined Contribution and Defined Benefit Plan Fractions is less than 1.0.

          By executing this Plan, the Primary Employer acknowledges having
