    Each document filed by the Company or the Plan pursuant to Sections 13(a),

ITEM 4.  DESCRIPTION OF SECURITIES

AUTHORIZED, ISSUED AND TREASURY SHARES

  The Company is authorized to issue 1,000,000,000 shares of common stock, par
value $0.01 per share ("Schlumberger Common Stock"), of which 665,712,058 shares
were issued; 547,193,933 shares were outstanding; and 118,518,125 shares were
held by the Company as treasury stock on May 31, 1999.  In addition, the Company
is authorized to issue, subject to certain limitations with respect to voting
rights, liquidation and dividend preferences, 200,000,000 shares of cumulative
preferred stock, par value $0.01 per share ("Schlumberger Preferred Stock"),
which may be issued in one or more separate series.  If issued, the Schlumberger
Preferred Stock may contain provisions allowing it to be converted into
Schlumberger Common Stock under terms and conditions specified by the Board of
Directors of the Company.  No shares of Schlumberger Preferred Stock have been
issued as of the date hereof.

DIVIDEND RIGHTS

  All outstanding shares of Schlumberger Common Stock (i.e., shares not held by
the Company and its subsidiaries), are entitled to participate equally and
receive dividends which may be paid out of available profits of the preceding
fiscal year or years.  All accumulated and unpaid dividends payable on
Schlumberger Preferred Stock (if issued and outstanding) must be paid prior to
the payment of any dividends on Schlumberger Common Stock.  The amount of
dividends payable with respect to any fiscal year is determined by the
stockholders at the annual general meeting held within nine months of such
fiscal year following such fiscal year, except that the Board of Directors may
declare interim dividends.

VOTING RIGHTS

  Each holder of shares of Schlumberger Common Stock is entitled to one vote for
each share registered in such holder's name.  Voting rights may be exercised in
person or by proxy.  No action to amend the Deed of Incorporation or to sell all
or substantially all of the Company's assets or to dissolve the Company can be
taken except upon the authorization of the holders of at least a majority of the
outstanding shares eligible to vote.  In addition, holders of Schulmberger
Preferred Stock (if issued and outstanding) would have additional rights to vote
as a class on certain amendments to the Company's Deed of Incorporation that
would adversely affect Schlumberger Preferred Stock.  Any other action requiring
the approval of the stockholders may be authorized by a majority of the votes
cast at any meeting at which a quorum is present, except that, if a quorum is
not present at any meeting, a second meeting may be called, to be held within
two months, at which second meeting, despite the absence of a quorum, valid
resolutions may be adopted with respect to any matter stated in the notice of
the original meeting and of the second meeting.  A quorum consists of not less
than 50% of the shares outstanding and eligible to vote.

  The Board of Directors of the Company is authorized to effect reorganizations
or rearrangements of the corporate structure of the Company or its subsidiaries
without the vote of stockholders if such reorganization or rearrangement does
not result in any diminution of the beneficial interest of the stockholders in
the assets of the Company.  The Board of Directors may change the Company's
corporate domicile from the Netherlands Antilles to another jurisdiction without
the necessity of any stockholder action or approval.

PREEMPTIVE AND OTHER RIGHTS

  The shares of Schlumberger Common Stock do not carry any preemptive or
conversion rights,  and there are no redemption provisions with respect to
Schlumberger Common Stock.  The shares of Schlumberger Preferred Stock (if
issued and outstanding) would not carry any preemptive rights, but the Board of
Directors could specify conversion rights, redemption provisions and (within
limits) liquidation preferences with respect to one or more series of Preferred
Stock.  The Company may for its own account purchase shares of Schlumberger
Common Stock so long as at least one-fifth of the authorized capital stock of
the Company remains outstanding with holders other than the Company.  In the
event of liquidation, each share of Schlumberger Common Stock is entitled to
equal rights after satisfaction of any Schlumberger Preferred Stock liquidation
preference.

LISTING, TRANSFER AGENTS AND REGISTRARS

  Schlumberger Common Stock is listed for trading on the New York, London,
Paris, Amsterdam and Swiss stock exchanges.  The Transfer Agent and Registrar
for Schlumberger Common Stock is Boston EquiServe LP, Boston, Massachusetts.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

    Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Article IX, Section 7 of the Company's Deed of Incorporation and Article V
of the Company's By-Laws provide that:

    The Company has the power to indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the Company) by reason of the fact
that he or she is or was a director, officer, employee or agent of the Company,
or is or was serving at the request of the Company as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise or entity, against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by him in connection with such action, suit or proceeding if he or she acted in
good faith and in a manner he or she reasonably believed to be in or not opposed
to the best interests of the Company, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, does not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he or she reasonably believed to be in or not opposed to

                                      II-1
<PAGE>

the best interests of the Company, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

    The Company has the power to indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action
or suit by or in the right of the Company to procure a judgment in its favor by
reason of the fact that he or she is or was a director, officer, employee or
agent of the Company, or is or was serving at the request of the Company as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise or entity against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him or her in connection with the defense or settlement
of such action or suit if he or she acted in good faith and in a manner he or
she reasonably believed to be in or not opposed to the best interests of the
Company and except that no indemnification may be made in respect of any claim,
issue or matter as to which that person has been finally adjudged to be liable
to the Company for improper conduct unless and only to the extent that the court
in which that action or suit was brought or any other court having appropriate
jurisdiction determines upon application that, despite the adjudication of
liability, but in view of all the circumstances of the case, that person is
fairly and reasonably entitled to indemnity for those expenses, judgments, fines
and amounts paid in settlement which the court in which the action or suit was
brought or such other court having appropriate jurisdiction deems proper.

    To the extent that a director, officer, employee or agent of the Company has
been successful on the merits or otherwise in defense of any action, suit or
proceeding referred to in the two preceding paragraphs, or in defense of any
claim, issue or matter therein, the Company will indemnify that person against
expenses (including attorneys' fees) actually and reasonably incurred by him or
her in connection therewith.

    Any indemnification under the first two paragraphs in this item (unless
ordered by a court) may be made by  the Company only as authorized by contract
approved, or by-laws, resolution or other action adopted or taken, by the Board
of Directors or by the stockholders.

    Expenses incurred in defending a civil or criminal action, suit or
proceeding will be paid by the Company in advance of the final disposition of
such action, suit or proceeding upon receipt of an undertaking by or on behalf
of the director, officer, employee or agent to repay such amount if it is
ultimately determined that he or she is not entitled to be indemnified by the
Company as authorized by Article V of the By-Laws or Article IX, Section 7 of
the Deed of Incorporation.

    The indemnification and advancement of expenses provided by or granted
pursuant to the other Sections of Article V of the By-Laws and Article IX,
Section 7 of the Deed of Incorporation are not exclusive of any other rights to
which those seeking indemnification or advancement of expenses may be entitled
under any law, by-law, agreement, vote of stockholders or disinterested
directors, or otherwise, both as to action in his or her official capacity and
as to action in another capacity while holding such office, and continues as to
a person who has ceased to be a director, officer, employee or agent and inures
to the benefit of the heirs, executors and administrators of that person.

    The Company has the power to purchase and maintain insurance on behalf of
any person who is or was a director, officer, employee or agent of the Company,
or is or was serving at the request of the Company in such a capacity for
another corporation, partnership, joint venture, trust or other enterprise
against any liability asserted against that person and incurred by that person
in any of those capacities or arising out of his status as such, whether or not
the Company may indemnify him or her against such liability under the provisions
of Article V of the By-Laws or Article IX, Section 7 of the Deed of
Incorporation.

    For purposes of Article V of the By-Laws and Article IX, Section 7 of the
Deed of Incorporation, reference to the Company includes, in addition to the
resulting corporation, any constituent corporation (including any constituent of
a constituent) absorbed in a consolidation or Merger which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers, and employees or agents, so that any person who is or was a
director, officer, employee or agent of such constituent corporation, or is or
was serving at the request of such constituent corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, stands in the same position under the provisions of
Article V of the By-Laws and Article IX, Section 7 of the Deed of Incorporation
with respect to the resulting or surviving corporation as he would have with
respect to such constituent corporation if its separate existence had continued.

                                      II-2
<PAGE>

    In addition, the Company maintains directors' and officers' liability
insurance which insures against certain liabilities that the officers and
directors of the Company may incur in such capacities.

("IRS") and hereby undertakes to submit any amendment thereto to the IRS in a
timely manner and will make all changes required by the IRS in order to qualify

ITEM 9.  UNDERTAKINGS

    (a)  The undersigned registrant hereby undertakes:

         (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 the registration statement (or the most
         recent post-effective amendment thereof) which, individually or in the
         aggregate, represent a fundamental change in the information set forth
         in the registration statement. 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) of the Securities Act if,
         in the aggregate, the changes in volume and price represent no more
         than a 20% change in the maximum aggregate offering price set forth in
         the "Calculation of Registration Fee" table in the effective
         registration statement;

             (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 the undertakings set forth in paragraphs (a)(1)(i) and
(a)(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

                                      II-3
<PAGE>

filed by the registrant pursuant to Section 13 or Section 15(d) of the Exchange
Act that are incorporated by reference in the registration statement.

         (2) That, for the purpose of determining any liability under the
    Securities Act of 1933, each such post-effective amendment shall be deemed
    to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.

         (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.

    (b)  The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, 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 this registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

    (c)  Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers, and controlling persons of
the registrant pursuant to the provisions described under Item 6 above, or
otherwise, the registrant has been advised that in the opinion of the Commission
such indemnification is against public policy as expressed in the Securities Act
and 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.

     which is 12;

            (b)  If compensation for any prior determination period is taken
     into account in determining an employee's benefits accruing in the current
     plan year, the compensation for that prior determination period is subject
     to the applicable compensation limit in effect for that prior determination
     period, and for this purpose, for determination periods beginning before

                                  ARTICLE II.

                       EMPLOYEES ELIGIBLE TO PARTICIPATE

     2.1.   Eligibility Requirements:  Subject to compliance with applicable
            ------------------------
provisions of Section 3.2, every Employee who was a participant in a Prior Plan
on the date immediately prior to the date such Prior Plan was amended, restated
and continued under the form of the Plan, shall be deemed to be a Participant
hereunder as of the date such Prior Plan was amended, restated and continued
under the form of the Plan.  With respect to Plan Years commencing prior to
January 1, 1989, every other Employee who has completed five (5) months or more
of Active Service shall be eligible to participate in the Plan as of the January
1 or July 1 coincident with or next following the later of (i) the effective
date of the adoption of the Plan by his Employer, or (ii) the date the Employee
satisfies the aforementioned eligibility requirements.  With respect to Plan
Years commencing on or after January 1, 1989, an Employee not described in the
first sentence of this paragraph shall be eligible to participate in the Plan as
of the Entry Date coincident with or next following the later of (i) the
effective date of the adoption of the Plan by his Employer, or (ii) the date
that the Employee completes one hour of Active Service.  Notwithstanding the
above, employees of the Reda Pump Division of TRW, Inc. ("Reda") who, as of the
date that the Plan Sponsor acquired substantially all of the assets of Reda,
satisfy the aforementioned eligibility requirements shall participate in the
Plan as of the date of such asset acquisition.

     In addition, pursuant to uniform and nondiscriminatory rules established by
the Committee with the consent or approval of the Board, the Committee may vote
to allow Employees (including Employees who would otherwise be excluded because
they are not working in covered employment) to enter the Plan as Participants on
any date which would not otherwise be permitted under the terms of the Plan.
Any such decision shall be evidenced by formal minutes reflecting such action of
the Committee or by a unanimous written consent of the members of the Committee
and shall be appropriately communicated to the affected Participants, and must
be approved or ratified by the Board, unless pursuant to the rules described in
the preceding sentence, approval or ratification by the Board is not required.

     If an individual who satisfies the requirements for participation in the
Plan separates from service of an Employer, but subsequently returns to active
employment with an Employer prior to incurring a period of five (or more)
consecutive one year periods of severance for eligibility, such person shall
become a Participant on the later of (i) the Entry Date on which such person
would otherwise initially be entitled to participate in the Plan or (ii) the
date he ended the above described period of separation from service. Upon an
individual's return to employment, (i) an Employee who had a vested and
nonforfeitable right to any portion of any amount credited to his Employer
Account at the time of his termination of employment and who incurred a period
of five (or more) consecutive one year periods of severance, or (ii) an Employee
who had no vested and nonforfeitable right to any amount credited to his
Employer Account at the time of his termination of employment and who has
incurred a period of five (or more) consecutive one year periods of severance,
which aggregate period is less than the aggregate number of years of Active
Service for eligibility (whether or not consecutive) completed prior to such
period, shall

                                     II-1
<PAGE>

be eligible to participate in the Plan immediately as of his return to the
employ of an Employer; provided, however, this sentence shall not apply in the
case of an Employee who completes at least one hour of service under the Plan or
Prior Plan on or after the Plan Year commencing after December 31, 1984 if the
Employee's prior period of Active Service would have been disregarded under
applicable provisions of the Plan or Prior Plan as of the date immediately prior
to the first day of the Plan Year beginning after December 31, 1984. Except with
respect to those situations specifically described in the preceding provisions
of this paragraph, upon an individual's return to covered employment, he will be
treated as a new Employee for eligibility purposes.

     Except as otherwise provided above, Employees who are included in a unit of
Employees covered by an agreement which the U.S. Secretary of Labor finds to be
a collective bargaining agreement between an Employees' representative and an
Employer shall be excluded from participation in the Plan if (i) there is
evidence that retirement benefits were the subject of good faith bargaining
between the Employees' representative and an Employer and (ii) the agreement
does not require an Employer to include such Employees in this Plan.  For
purposes of the preceding sentence the term "Employees' representative" shall
not include any organization more than one-half of the members of which are
Employees who are owners, officers or executives of an Employer.

     Notwithstanding any other provision of the Plan to the contrary, but
subject to the provisions of this paragraph, (i) any individual who was
considered by an Employer to be an independent contractor, but who is later
reclassified as a common-law Employee (excluding any Leased Employee described
in clause (ii) below) of an Employer with respect to any portion of the period
in which such individual was paid by an Employer as an independent contractor,
or (ii) any Leased Employee, shall be excluded from participation in the Plan
with respect to the period in which any individual described in clause (i) was
considered to be an independent contractor, or the period in which any
individual described in clause (ii) is a Leased Employee. The immediately
preceding sentence shall fully apply only with respect to Plan Years (or
portions thereof) in which none of the individuals described in such sentence is
required to be covered in order to ensure that the Plan is operated in
compliance with the requirements of Sections 401(a) and 410(b) of the Code. In
the event that any individual who is included in the class of reclassified
independent contractors described in clause (i) of the first sentence of this
paragraph, or who is a Leased Employee described in clause (ii) of the first
sentence of this paragraph, must be covered with respect to a Plan Year (or
portion thereof) in order to ensure that the requirements of the immediately
preceding sentence are met, starting with the class of reclassified independent
contractors, only such number of individuals within the class which includes the
individual (beginning with the individuals with the lowest Considered
Compensation determined on an annualized basis) as is necessary to ensure
compliance with the requirements of the immediately preceding sentence shall be
covered in the Plan only for the Plan Year (or portion thereof) that is
necessary to ensure that the requirements of the immediately preceding sentence
are met.

     2.2.  Frozen Participation:  While service with an Affiliated Employer
           --------------------
which is not an Employer is counted for purposes of determining Active Service,
no person shall authorize

                                     II-2
<PAGE>

Elective Contributions to the Plan except for the period(s) of service that he
is actually employed in covered employment with and paid by an Employer. If an
Employee is (i) transferred from an Employer to an Affiliated Employer which is
not an Employer or (ii) otherwise ceases to be employed in covered employment
with and paid by an Employer (but does not have a severance from service), his
Account shall thereupon be frozen: he shall not be permitted to authorize
contributions to the Plan, and his Account shall not share in the allocation of
any Employer Contribution (except for the period(s) of service that he is
actually employed in covered employment with and paid by an Employer), but his
Account will continue to share in any appreciation or depreciation of the Trust
Fund and in any income or losses incurred by the Trust Fund during the period of
time that he is employed by an Affiliated Employer which is not an Employer or
that he is otherwise excluded from covered employment; provided, however, he
shall continue to accrue Active Service.

     2.3.  Active Service:  For eligibility, vesting and all other pertinent
           --------------
purposes of the Plan, "Active Service" shall mean, subject to the transition
rules set out in the last paragraph of this Section, as to each Employee, the
number of whole years and complete months of the Employee's period(s) of service
with any Employer or Affiliated Employer, whether or not such period(s) of
service were completed consecutively.  Except as otherwise provided below, in
determining the number of whole years and complete months of an Employee's
period of service, non-successive periods of service shall be aggregated, and
less than whole year periods of service (whether or not consecutive) shall be
aggregated on the basis that twelve complete months of service (thirty days
shall be deemed to be a complete month in the case of aggregation of fractional
months) equal a whole year of Active Service.

     If an Employee severs from service by reason of a quit, discharge, or
retirement, and the Employee then performs an hour of service within twelve
months of the severance from service date, such Employee's period of severance
shall be deemed to have been a period of service.  If an Employee severs from
service by reason of a quit, discharge, or retirement during an absence from
service for any reason other than a quit, discharge, or retirement, and then
performs an hour of service within twelve months of the date on which the
Employee was first absent from service, such Employee's period of severance
shall be deemed to have been a period of service.

     Periods of severance taken into account as periods of service shall not be
taken into account for purposes of determining whether an Employee is in the
employ of the Employer for purposes of allocating Employer Contributions in
accordance with Section 4.2.

     For purposes of the Plan, all service with any Affiliated Employer shall be
deemed to be service with the Employer.  Furthermore, all covered service and
contiguous noncovered service with an Employer which has adopted the Plan but
which is not an Affiliated Employer shall be deemed to be service with the
Employer.

     In the event that an Employer assumes and maintains the plan of a
predecessor employer described in Section 414(a)(2) of the Code, Active Service
for such predecessor employer shall be treated as Active Service for the
Employer in accordance with the provisions of Section 414(a)(1) of the Code.
However, if the Employer does not maintain the plan of a predecessor

                                     II-3
<PAGE>

employer, the Plan shall treat any Employee's service with the predecessor
employer as service with the Employer only to the extent prescribed in Section
414(a)(2) of the Code.

     In addition, pursuant to uniform and nondiscriminatory rules established by
the Committee with the consent or approval of the Board, the Committee may vote
to allow Employees to be credited with Active Service for eligibility or vesting
with respect to periods of service which would otherwise be disregarded under
the Plan.  Any such decision shall be evidenced by formal minutes reflecting
such action of the Committee, or by unanimous written consent of the members of
the Committee, and must be approved or ratified by the Board, unless pursuant to
the rules described in the preceding sentence, approval or ratification by the
Board is not required.  Any such decision shall be appropriately communicated to
the affected Participants.  Subject to other applicable provisions of the Plan,
(i) Employees of acquired business units who are active Employees on both the
date of acquisition and October 1, 1988 shall receive full credit under the Plan
for purposes of eligibility and vesting for all periods of service with their
respective business units prior to the acquisition thereof by the Company, (ii)
effective December 1, 1996, Employees of acquired business units who are active
Employees on both the date of acquisition and the first anniversary of the date
of acquisition shall receive full credit under the Plan for purposes of vesting
for all periods of service with their respective business units prior to the
acquisition thereof by the Company and (iii) with respect to any acquisition
occurring after December 1, 1996, if specified in the merger, purchase and sale,
or other acquisition agreement, credit for service before such acquisition shall
be given to Employees of the acquired business unit for purposes of eligibility
and vesting under the Plan only to the extent specified in the acquisition
agreement by which the Company acquired the business unit by which such Employee
was employed immediately prior to such acquisition.

     Notwithstanding any other provision hereof, any period of service occurring
prior to the effective date of the adoption of the Plan by an Employer shall be
taken into account for purposes of determining vesting credit hereunder.  Except
as otherwise provided in Section 2.1, in the case of an Employee who has
incurred a one year period of severance, the period of service completed before
such period of severance shall not be taken into account until the Employee has
completed a one year period of service after his return to service.  With
respect to Plan Years beginning after December 31, 1984, in the case of an
Employee who completes at least one hour of service under the Plan or any Prior
Plan on or after the beginning of any Plan Year commencing after December 31,
1984, (i) if he has incurred five (or more) consecutive periods of severance,
the period of service completed after such period of severance shall not be
taken into account for purposes of determining the Participant's vested
percentage in amounts credited to his Employer Contributions Account prior to
such five (or more) consecutive periods of severance, and (ii) if he does not
have any vested right under the Plan to Employer Contributions credited to his
Account at the time he incurs a period of five (or more) consecutive one year
periods of severance, the period of service completed by such Employee before
such period of severance shall not be taken into account for any reason when the
period of five (or more) consecutive periods of severance equals or exceeds his
period of service, whether or not consecutive, completed before such period of
severance; provided, however, in the case of an Employee who completes at least
one hour of service under the Plan on or after the first day of the Plan Year
commencing after December 31, 1984, any period of service which would have

                                     II-4
<PAGE>

been disregarded under the Plan or any Prior Plan, as of the date immediately
prior to the first day of any Plan Year after December 31, 1984, shall not be
recognized under the Plan. In computing the aggregate period of service prior to
any such period of severance, any periods of service which may be disregarded by
reason of any prior periods of severance shall be disregarded.

     Subject to the transition rules set out in the last paragraph of this
Section, a "period of service" shall mean a period of service with any Employer
or Affiliated Employer commencing on the Employee's employment commencement date
or reemployment commencement date, whichever is applicable, and ending on the
severance from service date. "Employment commencement date" shall mean the date
on which the Employee first performs an hour of service initially. "Reemployment
commencement date" shall mean the date on which the Employee first performs an
hour of service following a period of severance not deemed to have been a period
of service.

     A "period of severance" shall mean the period of time commencing on the
severance from service date and ending on the date on which the Employee again
performs an hour of service.  A "one year period of severance" shall mean a 12-
consecutive-month period beginning on the severance from service date and ending
on the first anniversary of such date, if the Employee does not perform an hour
of service during such 12-consecutive-month period; provided, however, solely
for purposes of determining whether an Employee has incurred a one year period
of severance, any Employee who is absent from employment with the Employer or
Affiliated Employer for a period of absence which (1) begins after the first day
of the Plan Year beginning after December 31, 1984, and which is incurred by
reason of (i) the pregnancy of the Employee, (ii) the birth of a child of the
Employee, (iii) the placement of a child with the Employee in connection with
adoption of such child by the Employee or (iv) for purposes of caring for such
child for a period beginning immediately following such birth or placement, or
(2) begins on or after August 5, 1993, and to which the Employee is entitled
under the Family and Medical Leave Act of 1993, shall not be charged with a
period of severance with respect to (a) the 12-consecutive-month period
beginning on the first day of such absence or (b) the 12-consecutive-month
period commencing on the first anniversary of the first day of the period
described in clause (a) if the period in clause (a) is included in the
Employee's period of service.  The applicable 12-consecutive-month period
described in clause (a) or (b) shall be subtracted from any period of severance
which would otherwise include the period described in clause (a) or (b), as
applicable.

     An Employee's "severance from service date" shall occur on the earlier of
(i) the date on which the Employee quits, retires, is discharged, or dies; or
(ii) the first anniversary of the first day of a period in which the Employee
remains absent from service (with or without pay) for any reason other than a
quit, retirement, discharge, or death, such as vacation, holiday, sickness,
disability, leave of absence, or layoff. In addition, any period of absence
which is not described in the preceding sentence, which (1) begins on or after
the first day of the Plan Year beginning after December 31, 1984, and which is
incurred by reason of (i) the pregnancy of the Employee, (ii) the birth of a
child of the Employee, (iii) the placement of a child with the Employee in
connection with the adoption of such child by the Employee or (iv) for purposes
of caring for
                                     II-5
<PAGE>

such child for a period beginning immediately following such birth or placement,
or (2) begins on or after August 5, 1993, and to which the Employee is entitled
under Family and Medical Leave Act of 1993, shall be deemed to be a period of
absence described in clause (ii) of the preceding sentence.

     An "hour of service" shall mean an hour for which an Employee is paid, or
entitled to payment, for the performance of duties for any Employer or
Affiliated Employer.  "Covered service" shall mean service within a job
classification or class of employees covered under the Plan.  "Contiguous
noncovered service" shall mean service other than covered service, which
precedes or follows covered service, if no quit, discharge, or retirement occurs
between such covered service and such other service.

     Notwithstanding any other provision of the Plan to the contrary, the
provisions of this paragraph shall govern the method for determining and
crediting Active Service with respect to any Employee covered under any Prior
Plan.  For purposes of determining the Active Service of a Participant who was a
participant in and had an interest under a Prior Plan as of the date immediately
prior to the date that the Prior Plan was amended and continued under the form
of the Plan, such Participant shall be credited with Active Service (for his
period(s) of service prior to the date that the Prior Plan was amended and
continued under the form of the Plan) equal to the service determined and
credited to such Participant under applicable provisions of the Prior Plan as of
the date immediately prior to the date that the Prior Plan was amended and
continued under the form of the Plan.  For purposes of determining such
Participant's Active Service for the period(s) of service continuing or
commencing on or after the date that the Prior Plan was amended and continued
under the form of the Plan, such Participant's Active Service shall be
determined using the methods set out under applicable provisions of the Plan,
unless the Plan is retroactively effective as of a date which occurs within a
computation period of a Prior Plan (under which service credit was determined
with reference to computation periods and hours of service credited thereto).
In such event, Active Service shall be determined and credited with respect to
such computation period under applicable provisions of the Prior Plan if
necessary to ensure that a Participant does not lose service credit otherwise
recognizable under the Prior Plan with respect to such computation period, and
then Active Service of any such Participant for period(s) of service continuing
or commencing on or after the end of such computation period shall be determined
using the methods set out under applicable provisions of the Plan.

                                 CONTRIBUTIONS

     3.1.  Employee Voluntary Contributions:  Employee Voluntary Contributions
           --------------------------------
(defined below) on the part of the Participants shall be permitted from time to
time as determined by the Board.  "Employee Voluntary Contributions" shall mean
after-tax amounts contributed to the Plan by a Participant which are not
required as a condition of employment, as a condition of participation in the
Plan or as a condition to obtaining benefits (or additional benefits) under the
Plan attributable to Employer Contributions.  Employee Voluntary Contributions
shall not be deductible or excludible from the Participant's gross income.

     In the event Employee Voluntary Contributions are permitted, the
opportunity to contribute shall be announced and made available to all
Participants upon an equal basis in the manner hereinafter set out. Once
Employee Voluntary Contributions have been permitted, if the Committee
determines to stop Employee Voluntary Contributions, an announcement shall be
made to all Employees and the Contributions to the effective date of the
announcement shall be retained in the Plan subject to the terms and provisions
of the Plan including the right of withdrawal by the Participants under Section
6.8.

     From and after the date, if any, established by the Board, or the Entry
Date or other date with respect to which a Participant is eligible to
participate, if later, each Participant may execute a written agreement in a
form satisfactory to the Committee whereunder the Participant shall agree,
subject to any necessary adjustments pursuant to Sections 3.4 and 4.3, (i) to a
reduction of not less than one percent (1%) nor more than ten percent (10%) of
his Considered Compensation attributable to the applicable pay periods, and (ii)
to contribute the amount of the authorized reduction to the Plan as an Employee
Voluntary Contribution. Any such reduction authorized by the Participant within
the limits set forth in the previous sentence may be either a percentage or a
dollar amount of Considered Compensation each applicable payroll period.

     All Employee Voluntary Contributions shall be made by periodic payroll
deductions on such uniform basis as shall be determined from time to time by the
Committee.  An Employer shall deposit each Participant's Employee Voluntary
Contribution with the Trustee within thirty (30) days after its deduction.  The
Committee shall credit the Participant's Employee Voluntary Contribution to his
Employee Account.  For Plan Years beginning on and after January 1, 1995, a
Participant shall be allowed to increase, decrease, or cease his Voluntary
Employee Contributions at any time, with any such change being effective as of
the first day of the first pay period thereafter that is administratively
feasible.

     3.2.  Compensation Deferral Agreements for Elective Contributions:

           (a)   Compensation Deferral Agreements:  Subject to applicable
                 --------------------------------
     conditions and limitations of the Plan, at such time or times as may be
     permitted by the Board, and in such manner and amounts as shall be
     consistent with the provisions of this Section, in lieu of receipt of such
     amounts in cash, Participants may authorize an Employer to make

                                     III-1
<PAGE>

     Elective Contributions to the Plan on their behalf. Elective Contributions
     shall be held, invested and distributed as provided under applicable
     provisions of the Plan. Provided, however, no Compensation Deferral
     Agreement (or any other deferral mechanism that may be permitted under the
     Plan) may be adopted retroactively. In the event Elective Contributions are
     permitted, the opportunity to authorize Elective Contributions hereunder
     shall be announced and made available to all Participants upon an equal
     basis. Once Elective Contributions have been permitted, if the Committee
     determines to stop Elective Contributions, an announcement shall be made to
     all Employees and the Elective Contributions to the effective date of the
     announcement shall be retained in the Plan subject to the other terms and
     provisions of the Plan including any right of withdrawal under Section 6.8.

          From and after the date, if any, established by the Board pursuant to
     the preceding paragraph of this Section, or the Entry Date or other date
     with respect to which a Participant is eligible to participate, if later,
     each Participant may execute a Compensation Deferral Agreement in a form
     satisfactory to the Committee whereunder the Participant shall agree,
     subject to any necessary adjustments pursuant to this Section and Sections
     3.4 and 4.3, (i) to a reduction of not less than one percent (1%) nor more
     than fifteen percent (15%) of his Considered Compensation (before such
     authorized reduction) attributable to the applicable pay periods, and (ii)
     to have an Employer contribute (as an Elective Contribution) to the Plan an
     amount equal to the amount of the authorized reduction, which Elective
     Contribution shall be allocated and credited to the Participant's Employer
     Nonforfeitable Contributions Account. The election shall separately specify
     the reduction, if any, applicable to any Considered Compensation to be
     received on a non-periodic basis, or on the basis of periods no more
     frequent than calendar quarters. Any reduction authorized by the
     Participant within the limits set forth in the previous two sentences may
     be either a percentage or a dollar amount of Considered Compensation each
     applicable payroll period. The term "payroll period" shall mean the regular
     pay periods at the end of which compensation is paid, whether that
     compensation is a regular or a non-periodic payment.

          For Plan Years beginning on and after January 1, 1995, reductions
     authorized under Compensation Deferral Agreements shall be irrevocable,
     except that Elective Contributions may be discontinued, increased or
     decreased by a Participant at any time, with any such change being
     effective as of the first day of the first pay period thereafter that is
     administratively feasible. Under special circumstances, pursuant to
     uniformly applied nondiscriminatory rules established by the Committee, the
     Committee may permit different or additional effective dates for increases
     or decreases of Elective Contributions authorized under Compensation
     Deferral Agreements, or may waive the otherwise applicable notice
     requirement, in order to prevent hardship to any Participant, provided that
     the waiver is not contrary to the best interests of the other Participants.

          (b)  Special Compensation Deferral Agreements:  Notwithstanding the
               ----------------------------------------
     preceding subsection, unless the Committee otherwise determines in its sole
     discretion, prior to the first day of the last month of the Plan Year, each
     Participant may execute a

                                     III-2
<PAGE>

     Compensation Deferral Agreement (in such form as is satisfactory to the
     Committee and hereinafter referred to as a "Special Compensation Deferral
     Agreement") providing for an increase or a reduction of Elective
     Contributions with respect to any part or all of the Participant's
     Considered Compensation for any part or all of the last month of the Plan
     Year; provided, however, (i) that such Special Compensation Deferral
     Agreement shall be deemed to modify and override any prior Compensation
     Deferral Agreement during the period covered by the Special Compensation
     Deferral Agreement, (ii) that the deferrals authorized under the Special
     Compensation Deferral Agreement may be increased, reduced or revoked only
     if permitted by the Committee in accordance with uniformly applied
     nondiscriminatory rules which may be established by the Committee, and
     (iii) that the Special Compensation Deferral Agreement shall automatically
     terminate as of the earlier of such time (a) it is revoked by the
     Participant in accordance with uniformly applied nondiscriminatory rules
     established by the Committee or (b) the last day of the period with respect
     to which authorized reductions thereunder are contributed to the Plan. All
     deferrals required as a result of the execution of a Special Compensation
     Deferral Agreement shall be subject to all applicable terms, conditions,
     and limitations of the Plan. As of the date that the Special Compensation
     Deferral Agreement ceases to be operative, the Participant's then otherwise
     operative Compensation Deferral Agreement shall govern deferrals to be made
     on behalf of the Participant.

          (c)  Dollar Limit On Elective Deferrals:  Notwithstanding any other
               ----------------------------------
     provision of the Plan to the contrary, with respect to any taxable year of
     any Participant beginning after December 31, 1986, deferrals under the Plan
     in lieu of cash Considered Compensation, pursuant to any Compensation
     Deferral Agreement and Special Compensation Deferral Agreement, when added
     to (i) any employer contribution under any other cash or deferred
     arrangement (described in Section 401(k) of the Code) to the extent not
     includible in gross income for the taxable year under Section 402(a)(8) of
     the Code, (ii) any employer contribution (to a simplified pension plan
     under a salary reduction agreement) to the extent not includible in gross
     income for the taxable year under Section 402(h)(1)(B) of the Code, (iii)
     any employer contribution to purchase an annuity contract (described in
     Section 403(b) of the Code) under a salary reduction agreement (within the
     meaning of Section 3121(a)(5)(D) of the Code) to the extent not includable
     in gross income for the taxable year under Section 403(b) of the Code, and
     (iv) any employer contribution (pursuant to any election to defer under any
     eligible deferred compensation plan) to the extent not includable in gross
     income under Section 457 of the Code, are limited to $7,000 (as adjusted,
     as may be determined by the Commissioner of Internal Revenue, at the same
     time and in the same manner as prescribed in Section 415(d) of the Code).
     In addition, without limiting the scope of the immediately preceding
     sentence, with respect to any Plan Year or taxable year of any Participant
     which begins after December 31, 1987, Elective Contributions and/or any
     similar elective deferrals (described in Section 402(g)(3) of the Code) to
     the Plan and/or any other qualified plan, contract or arrangement, which is
     described in the immediately preceding sentence and maintained by an
     Employer and/or any Affiliated Employer, shall not in the aggregate exceed
     the dollar limitation (as adjusted) of the immediately preceding sentence
     and Section 402(g) of the Code as in effect at the beginning of such
     taxable year.

          (d)  Remedying Excess Deferrals:  To the extent that a Participant's
               --------------------------
     elective deferrals, authorized pursuant to the Sections of the Code
     referenced in the immediately preceding subsection, exceed the applicable
     limit for the applicable year so that any amount otherwise excludable from
     such Participant's gross income for federal income tax purposes is
     includible in his gross income, then, not later than the first March 1
     following the close of the taxable year of such excess deferral, the
     Participant shall notify the Committee in writing of any portion of any
     such excess deferrals which the Participant has elected to allocate to the
     Plan. Such notice shall include the Participant's certified written claim
     for a specified amount of excess deferrals for the preceding calendar year
     and shall be accompanied by the Participant's certified written statement
     that if such amounts are not distributed, such excess deferrals, when added
     to amounts deferred under other plans or arrangements described in Sections
     401(k), 408(k), 403(b) or 457 of the Code, exceeds the limit imposed under
     Section 402(g) of the Code for the year in which the deferral occurred. In
     accordance with Section 1.402(g)-1(e)(2) of the income tax regulations, to
     the extent that the Participant only has elective deferrals for the taxable
     year under the Plan and any other plan or arrangement described in the
     previous sentence which is maintained by the same Employer, such Employer
     may notify the Committee of any excess deferrals made on behalf of the
     Participant.

          Following actual receipt by the Committee of the notice described in
     the immediately preceding paragraph, (notwithstanding any other provision
     of law or the Plan relating to spousal consent), not later than the first
     April 15 immediately following such March 1 deadline for written
     notification of the Committee, the Plan shall distribute to such
     Participant in a lump sum (in cash or in kind) the amount of excess
     elective deferrals allocated to the Plan (and any income allocable to such
     amount). Such distribution shall be made first by distribution of
     nonmatched Elective Contributions, if any, allocated to the Participant's
     Employer Nonforfeitable Contributions Account, and, if necessary, next by
     distribution of Elective Contributions which were made on behalf of the
     Participant and were matched by Matching Contributions. Subject to the
     subsequent provisions of this paragraph, to the extent that such excess
     deferrals are attributable to matched Elective Contributions (and any
     income allocable thereto) which amounts are distributed to the Participant
     pursuant to the preceding provisions of this Section, Matching
     Contributions (and any income allocable thereto) will be appropriately
     reduced and such reduced Matching Contributions (and any income allocable
     thereto) shall be applied as forfeitures pursuant to Section 4.6. Such
     reduction shall be made first by reduction of Matching Contributions
     allocated to the Participant's Employer Nonforfeitable Contributions
     Account, and, if necessary, next by reduction of Matching Contributions
     allocated to the Participant's Employer Contributions Account. The
     provisions of this paragraph (which provide for reduction of Matching
     Contributions made with respect to Elective Contributions which are
     distributed hereunder) are intended to comply with the requirements of
     Sections 401(a), 401(k), 401(m) and 411 of the Code and regulations or
     other authority issued thereunder by the appropriate governmental
     authority. To the extent that any provision of this paragraph is
     inconsistent with the preceding sentence, such provision shall be deemed to
     be inoperative and the

                                     III-4
<PAGE>

     plan shall be operated in a manner that complies with the requirements of
     the immediately preceding sentence.

          Income or loss allocable to the portion of the Participant's Employer
     Nonforfeitable Contributions Account that is attributable to excess
     elective deferrals (described below) shall be income or loss for the
     taxable year allocable to the portion of Participant's Employer
     Nonforfeitable Contributions Account that is attributable to elective
     deferrals multiplied by a fraction, the numerator of which is the
     Participant's excess elective deferrals for the year and the denominator of
     which is the balance as of the end of such year of the portion of the
     Participant's Employer Nonforfeitable Contributions Account that is
     attributable to elective deferrals reduced by any gain and increased by any
     loss allocable to such balance for the taxable year. In the event that a
     separate subaccount is not maintained with respect to elective deferrals
     attributable to Elective Contributions (and any income allocable thereto),
     the portion of an Employer Nonforfeitable Contributions Account which is
     attributable to elective deferrals is determined by multiplying the balance
     of the Participant's Employer Nonforfeitable Contributions Account by a
     fraction, the numerator of which is an Elective Contributions made to the
     Plan on behalf of the Participant and allocated and credited to the
     Participant's Employer Nonforfeitable Contributions Account less any
     permitted withdrawals, and the denominator of which is the sum of all
     Employer Contributions made to the Plan on behalf of the Participant and
     allocated and credited to the Participant's Employer Nonforfeitable
     Contributions Account less any permitted withdrawals. Similar rules apply
     with respect to determination of Matching Contributions allocated to an
     Employer Contributions Account and any income allocable thereto. No income
     or loss will be allocated for the gap period between the end of the taxable
     year to the date of distribution for Plan Years beginning on or after
     January 1, 1992 and, with respect to Plan Years beginning before such date,
     income or loss shall be allocated in accordance with the applicable income
     tax regulations and Plan document as then in effect.

          Notwithstanding the preceding provisions of this subsection, any
     Participant who has excess elective deferrals for a taxable year may
     receive a corrective distribution of such deferrals (and income
     attributable thereto) during the same year if the Participant notifies the
     Committee of an excess deferral, the correcting distribution is made after
     the date on which the Plan received the excess deferral and the Plan
     designates and treats the distribution as a distribution of an excess
     deferral. Any distribution described in the immediately preceding sentence
     shall be made as soon as practicable, but absent circumstances beyond the
     control of the Committee, not later than 60 days after the first day of the
     month that occurs on or after the later of (i) the actual receipt by
     Committee of the Participant's notification of an excess deferral or (ii)
     the date that the Plan actually receives the excess elective deferral. The
     income allocable to elective deferrals from the first day of the taxable
     year to the date of the distribution shall be determined by using the
     method described in the immediately preceding paragraph.

                                     III-5
<PAGE>

           Notwithstanding any other provision of this Section to the contrary,
     with respect to taxable years that began in 1987, the method employed by
     the Plan (of such time) for computing the income allocable to excess
     deferrals for such taxable year, shall supersede and override any
     inconsistent provisions of this Section. Provided, however, the provisions
     of the immediately preceding sentence shall not apply with respect to
     taxable years beginning after 1987.

           Notwithstanding any other provision of this subsection to the
     contrary, the amount of excess deferrals that may be distributed under this
     subsection shall be reduced by any excess contributions over the ADP limit
     (described in Section 3.4) previously distributed or recharacterized with
     respect to a Participant for the Plan Year beginning with or within such
     Participant's taxable year. In no event shall any Participant receive from
     the Plan a corrective distribution for the taxable year of an amount in
     excess of the Participant's total elective deferrals under the Plan for the
     taxable year. Except as may be otherwise required under Section 3.4, any
     excess deferral not timely distributed shall remain in the Plan and shall
     be subject to otherwise applicable terms, provisions, conditions and
     limitations thereof. In addition, any excess elective deferrals shall be
     treated as annual additions under Section 4.3. In addition, any excess
     deferrals which are timely distributed under the preceding provisions of
     this subsection shall not be treated as an annual addition under Section
     4.3. Also, excess deferrals by Non-Highly Compensated Employees shall not
     be taken into account under the actual deferral percentage test of Section
     3.4 to the extent such excess deferrals are made under the Plan or any
     other qualified plan of an Employer or any Affiliated Employer. A
     distribution of elective deferrals (and allocable income thereon) under
     this subsection shall not be considered as a distribution for purposes of
     compliance with the minimum distribution provisions of Section 6.6.

     3.3.  Rollover Contributions:  Rollover Contributions on the part of the
           ----------------------
Employees shall be permitted from time to time as determined by the Committee.
In the event Rollover Contributions are permitted, the opportunity to contribute
shall be made available to Employees upon a nondiscriminatory basis.  An
Employee who is permitted to make a Rollover Contribution shall not be entitled
to authorize Elective Contributions to the Plan or share in the allocation of
any Employer Contributions unless and until the Employee meets the requirements
of Sections 2.1, 3.2 and 4.2 of the Plan.  Any such Rollover Contribution made
by an Employee shall be held in a separate Rollover Account for such Employee
which will share in any income or losses and/or appreciation or depreciation of
the Trust Fund.  Rollover Contributions shall not be considered Employee
Voluntary Contributions under this Plan and shall have no effect upon any
limitation under the Plan based upon a Participant's Contributions.

     3.4.  Employer Contributions:
           ----------------------

           (a)   Elective Contributions:  Subject to the applicable limitations
                 ----------------------
     of the Plan set forth below, each periodic pay period an Employer shall
     contribute to the Trust Fund (without regard to its Net Income or
     accumulated earnings and profits) Elective Contributions for each
     Participant in an amount equal to the amount by which the

                                     III-6
<PAGE>

     Participant's Considered Compensation was reduced pursuant to a
     Compensation Deferral Agreement (and, if applicable, Special Compensation
     Deferral Agreement) executed by the Participant pursuant to Section 3.2.

          (b)  Matching Contributions:  Subject to the applicable limitations of
               ----------------------
     the Plan set forth below, in addition to the Elective Contributions
     described in the preceding subparagraph, with respect to each month of the
     Plan Year (or such other period as may be prescribed by the Board), an
     Employer may, in the discretion of the Board, contribute to the Trust Fund
     (without regard to its Net Income or accumulated earnings and profits)
     Matching Contributions on behalf of each eligible Participant in an amount
     equal to the lesser of fifty percent (50%) of the amount by which the
     Participant's Considered Compensation was reduced for the month (or such
     other period as may be prescribed by the Board) pursuant to a Compensation
     Deferral Agreement (and, if applicable, Special Compensation Deferral
     Agreement) under Section 3.2, not to exceed the "maximum dollar amount" as
     defined in the immediately succeeding sentence for the month (or such other
     period as may be prescribed by the Board), or such other percentage or
     dollar amount as may be established by the Board pursuant to uniformly
     applied nondiscriminatory rules. The "maximum dollar amount" shall be: (i)
     for periods prior to June 1, 1992: $90 per month; (ii) for periods
     beginning on or after June 1, 1992 and before January 1, 1996: the first
     $2,160 of Elective Contributions made on behalf of the Participant during
     the applicable calendar year; and (iii) for periods beginning on and after
     January 1, 1996: the first $3,000 of Elective Contributions made on behalf
     of the Participant during the applicable calendar year. Any decision to
     provide a Matching Contribution for any Plan Year (or such other period as
     may be prescribed by the Board) or any increase or decrease in the
     percentage or dollar amount in effect from time to time, shall be
     communicated to all eligible Employees at least seven (7) days prior to the
     date on which eligible Employees are required to inform the Committee of an
     increase or decrease in their Elective Contributions under a Compensation
     Deferral Agreement (and, if applicable, a Special Compensation Deferral
     Agreement) pursuant to Section 3.2.

          (c)  Profit Sharing Contributions:  Subject to applicable limitations
               ----------------------------
     of the Plan set forth below, with respect to each Plan Year, an Employer
     may contribute to the Trust Fund (from its Net Income or accumulated
     earnings and profits) Profit Sharing Contributions in such amount as shall
     be determined by the Board in its discretion. Profit-Sharing Contributions,
     if any, shall be made on behalf of each Participant who remains in the
     employ of an Employer on the last day of the Plan Year, notwithstanding the
     fact that the Participant did not elect to reduce his Considered
     Compensation pursuant to a Compensation Deferral Agreement (and, if
     applicable, a Special Compensation Deferral Agreement) under Section 3.2 at
     any time during such Plan Year. For purposes of the preceding sentence, any
     Participant whose employment terminates on account of retirement, Total and
     Permanent Disability or death, shall be deemed to be in the employ of an
     Employer on the last day of the Plan Year in which such termination of
     employment occurs.

                                     III-7
<PAGE>

          In addition, notwithstanding any other provision of the Plan to the
     contrary, (i) any Participant whose employment terminates prior to the last
     day of the Plan Year or who would otherwise not be treated as employed in
     covered employment on the last day of the Plan Year, shall, nevertheless,
     be treated as employed on the last day of the Plan Year to the extent
     necessary to ensure compliance with Section 401(a)(4), Section 401(a)(26)
     and/or Section 410(b) of the Code; and (ii) any Participant who is, on the
     last day of the Plan Year (or applicable shorter period), on a leave of
     absence to which such Participant is entitled under the Family and Medical
     Leave Act of 1993 ("FMLA") shall be deemed to be in the employ of the
     Employer on such last day unless final regulations issued under the FMLA do
     not require such treatment for this purpose.

          (d)  Qualified Non-Elective Contributions:  At the election of the
               ------------------------------------
     Board, in lieu of distributing or recharacterizing excess Employer
     Contributions to Highly Compensated Employees in order to satisfy the
     actual deferral percentage test or the actual contribution percentage test,
     as described below in this Section, an Employer may make Qualified Non-
     Elective Contributions on behalf of Non-Highly Compensated Employees who
     are Participants in such amounts as are sufficient to satisfy the actual
     deferral percentage test or the actual contribution percentage test, as
     applicable. Qualified Non-Elective Contributions, if any, shall be made on
     behalf of each Participant who (i) is a Non-Highly Compensated Employee and
     (ii) remains in the employ of an Employer as of the last day of the Plan
     Year. For purposes of the preceding sentence, any Participant whose
     employment terminates on account of retirement, Total and Permanent
     Disability, or death, shall be deemed to be in the employ of an Employer on
     the last day of the Plan Year in which the termination of employment
     occurred.

          In addition, notwithstanding any other provision of the Plan to the
     contrary, any Participant whose employment terminates prior to the last day
     of the Plan Year or who would otherwise not be treated as employed in
     covered employment on the last day of the Plan Year, shall, nevertheless,
     be treated as employed on the last day of the Plan Year to the extent
     necessary to ensure compliance with Section 401(a)(4), Section 401(a)(26)
     and/or Section 410(b) of the Code; and (ii) any Participant who is, on the
     last day of the Plan Year (or applicable shorter period), on a leave of
     absence to which such Participant is entitled under the Family and Medical
     Leave Act of 1993 ("FMLA") shall be deemed to be in the employ of the
     Employer on such last day unless final regulations issued under the FMLA do
     not require such treatment for this purpose.

          (e)  Restoration of Forfeited Benefits:  Not later than the last day
               ---------------------------------
     of the Plan Year in which occurs any repayment described in Section 4.6, an
     Employer shall contribute (without regard to its Net Income or accumulated
     earnings and profits) an amount which, when added to previously unapplied
     and unallocated forfeitures, shall be equal to the amount previously
     forfeited under applicable provisions of the Plan by any Participant
     entitled to have his Account restored in accordance with Section 4.6. In
     addition, as soon as administratively practicable following receipt of a
     claim under circumstances described in Section 6.7, an Employer shall
     contribute (without regard to its Net

                                     III-8
<PAGE>

     Income or accumulated earnings and profits) an amount equal to the value of
     the forfeited benefits described in and payable under Section 6.7.

          (f)  Top-Heavy Minimum Contribution:  In the event that the Plan is a
               ------------------------------
     Top-Heavy Plan described in Article VII with respect to any Plan Year, an
     Employer shall contribute (without regard to its Net Income or accumulated
     earnings and profits) any amount necessary to ensure that Participants who
     are entitled to a minimum allocation pursuant to Section 7.3(c) in fact
     receive such allocation.

          (g)  Contribution Limits:  No Contribution by an Employer shall exceed
               -------------------
     a sum equal to fifteen percent (15%) of the total compensation paid or
     accrued during its taxable year ending with or within the Plan Year to all
     Participants.

          No Contribution shall be made to the Plan under circumstances which
     would result in any violation of the limitations of Section 3.2, this
     Section 3.4 or Section 4.3 of the Plan. An Employer shall maintain such
     records as may be necessary to demonstrate compliance with the
     nondiscrimination tests set forth below in this Section.

          (h)  Actual Deferral Percentage Test:  The actual deferral percentage
               -------------------------------
     ("ADP") for all eligible Highly Compensated Employees shall not exceed the
     greater of:

               (i)  the actual deferral percentage for the group of
          all eligible Non-highly Compensated Employees multiplied by
          1.25, or

               (ii) the actual deferral percentage of the group of all
          eligible Non-highly Compensated Employees multiplied by 2.0;
          provided, however, that the actual deferral percentage for
          the group of eligible Highly Compensated Employees may not
          exceed the actual deferral percentage of the group of all
          eligible Non-Highly Compensated Employees by more than two
          percentage points (2%).

     Unless otherwise elected by the Employer, the relationship of the ADP for
     all eligible Highly Compensated Employees for a specific Plan Year shall be
     determined with respect to the ADP for all eligible Non-Highly Compensated
     Employees for the Plan Year preceding such Plan Year. For Plan Years
     commencing after December 31, 1986, the provisions of Section 401(k)(3) of
     the Code and Section 1.401(k)-1(b) of the income tax regulations are hereby
     incorporated into the Plan for all purposes. In addition, for Plan Years
     beginning after December 31, 1988, if (i) any Highly Compensated Employee
     is eligible to authorize Elective Contributions under the Plan and to have
     Matching Contributions allocated with respect to an Elective Contributions
     or (ii) such Highly Compensated Employee is eligible to make elective
     deferrals (described in Section 402(g)(3) of the Code) under any other cash
     or deferred arrangement (described in Section 401(k) of the Code) and/or to
     make employee contributions (described in Section 401(m) of the Code) or to
     receive matching contributions (described in Section 401(m) (4)(A) of the
     Code) under any other qualified plan of an Employer and/or any Affiliated

                                     III-9
<PAGE>

     Employer regardless of whether such plan contains a cash or deferred
     arrangement, the disparities between the actual deferral percentages of the
     respective groups of eligible Highly Compensated Employees and Non-Highly
     Compensated Employees shall be reduced as described in Section 1.401(m)-2
     of the income tax regulations, and the provisions of subsection (k) below.

          Subject to the provisions of the Plan set forth below, the actual
     deferral percentage for a specified group of eligible Employees for a Plan
     Year shall be the average of the actual deferral ratios (calculated
     separately for each Employee in such group) of the sum of Elective
     Contributions, Qualified Non-Elective Contributions, if any, and Profit
     Sharing Contributions, if any, actually paid over to the Trust Fund on
     behalf of each such Employee for such Plan Year, and allocated to the
     Employee's Employer Nonforfeitable Contributions Account for such Plan
     Year, to the Employee's Compensation (described in the immediately
     succeeding sentence) for the Plan Year. For the purposes of performing the
     ADP test, Compensation shall mean all remuneration:

               (i)   that is (a) received during the Plan Year by the
          eligible Employee from an Employer and is required to be
          reported as wages on the eligible Employee's form W-2 (or
          its successor) for federal income tax withholding purposes
          (or, in the case of a nonresident alien employee, is the
          type of income that would be required to be reported as
          wages on form W-2 if such employee were subject to such
          reporting requirements), but determined without regard to
          any rules that limit the remuneration included in wages
          based on the nature or location of the employment or the
          services performed (such as the exception for agricultural
          labor in Section 3401(a)(2) of the Code), plus (b) any
          reduction under a compensation deferral agreement under (1)
          a plan described in Section 401(k) or 408(k) of the Code,
          (2) an annuity described in Section 403(b) of the Code or
          (3) an election under a cafeteria plan described in Section
          125 of the Code,

               (ii)  that, subject to clause (iv) below, is actually
          paid to or is includible (within the meaning of Section
          1.415-2(d)(3) and (4) of the income tax regulations) in the
          gross income of the eligible Employee within the relevant
          Plan Year, or would have been so paid or includible but for
          a reduction described in clause (i) immediately above,

               (iii) that does not exceed (A) for Plan Years beginning
          on or after January 1, 1989 and before January 1, 1994,
          $200,000 and (B) for Plan Years beginning on or after
          January 1, 1994, $150,000 (as adjusted at such time and in
          such manner as is prescribed in Section 401(a)(17)(B) of the
          Code), and

               (iv)  that is received by the eligible Employee during
          the entire Plan Year and not only while he is a Participant.

                               III-10
<PAGE>

          For the purposes of the immediately preceding paragraph, provided that
     the actual deferral percentage test is satisfied both with and without
     exclusion of these Elective Contributions, Elective Contributions shall
     include excess elective deferrals described in Section 3.2 (even if
     distributed under Section 3.3) made by Highly Compensated Employees, as
     well as all Elective Contributions made by all Participants that are not
     taken into account in the ACP test described in a subsection below. In
     accordance with Section 1.402(g)-1(e)(iii) of the income tax regulations,
     excess elective deferrals described in Section 3.2 made by Non-Highly
     Compensated Employees, to the extent made under the Plan or a plan
     maintained by an Affiliated Employer, shall not be taken into account under
     the ADP test described in this subsection.

          For the purpose of calculating the actual deferral percentages
     hereunder, subject to and in accordance with regulations or other authority
     issued under Sections 401(k) and/or 401(m) of the Code by the appropriate
     governmental authority, only such portion of the applicable Contributions
     (as described in the second previous paragraph) as may be necessary to
     ensure compliance with the actual deferral percentage test shall be taken
     into account for purposes of that test. With respect to Plan Years
     commencing after December 31, 1988, such actual deferral ratios of each
     eligible Employee and the actual deferral percentage of each group shall be
     calculated to the nearest one-hundredth of one percent of the eligible
     Employee's Compensation. The actual deferral ratio of an eligible Employee
     is zero if no applicable Contributions were allocated to such Employee's
     Employer Nonforfeitable Contributions Account for the Plan Year.

          In accordance with the requirements of Section 1.401(k)-1(b)(3) of the
     income tax regulations, two or more cash or deferred arrangements (as
     defined in Section 401(k) of the Code) may be considered one such
     arrangement for purposes of determining whether such arrangements satisfy
     the requirements of Sections 401(a)(4), Section 401(k) and 410(b) of the
     Code. In such case, the cash or deferred arrangements included in such
     plans and the plans including such arrangements shall be treated as one
     arrangement and as one plan for purposes of applying this Section and
     Sections 401(a)(4), 401(k) and 410(b) of the Code. If an Employer and any
     Affiliated Employer individually or collectively maintain two or more plans
     that are treated as a single plan for purposes of Section 401(a)(4) or
     410(b) of the Code (other than Section 410(b)(2)(A)(ii) of the Code as in
     effect for Plan Years which begin after December 31, 1988), all cash or
     deferred arrangements that are included in such plans are to be treated as
     a single arrangement for purposes of this Section and Sections 401(a)(4),
     401(k) and 410(b) of the Code. For Plan Years beginning after December 31,
     1989, plans may be aggregated under the preceding provisions of this
     paragraph only if they have the same Plan Year. With respect to Plan Years
     beginning after December 31, 1986, if any Highly Compensated Employee is a
     participant under two or more cash or deferred arrangements (as defined in
     Section 401(k) of the Code) of an Employer, for purposes of determining the
     actual deferral ratio with respect to such Highly Compensated Employee, all
     such cash or deferred arrangements shall be treated as one cash or deferred
     arrangement. For Plan Years beginning after December 31, 1988, if a Highly
     Compensated Employee participates in

                                    III-11
<PAGE>

     two or more cash or deferred arrangements that have different plan years,
     the immediately preceding sentence shall be applied by treating all cash or
     deferred arrangements with years ending with or within the same calendar
     year as a single arrangement. For Plan Years beginning after 1988,
     contributions and allocations under an employee stock ownership plan
     described in Section 4975(e)(7) of the Code may not be combined with
     contributions or allocations under any plan not described in Section
     4975(e)(7) of the Code.

          With respect to Plan Years beginning prior to January 1, 1992, the
     Plan or, if the Plan is aggregated with another cash or deferred
     arrangement pursuant to the previous paragraph, such aggregated Plan may,
     in the discretion of the Committee, be restructured (in accordance with
     Sections 1.401(k)-1(h)(3)(iii), 1.401(a)(4)-1(c)(8)(iii) and 1.401(a)(4)-
     9(c) of the income tax regulations into two or more component plans for
     purposes of determining whether the Plan or aggregated Plan satisfies
     Section 401(a))(4) of the Code and the actual deferral percentage test set
     forth above. If each of the component plans of the Plan or aggregated Plan
     satisfies all of the requirements of Sections 401(a)(4) and 410(b) of the
     Code as if it were a separate Plan or aggregated Plan, then the Plan or
     aggregated Plan is treated as satisfying Section 401(a)(4) of the Code. If
     the Plan or aggregate Plan is restructured into component plans for
     purposes of testing for compliance with Section 401(a)(4) of the Code and
     the actual deferral percentage test, each component plan resulting from
     such restructuring shall consist of all of the allocations, accruals, and
     other benefits, rights and features provided to a group of Employees under
     the Plan or aggregated Plan. Each Employee is permitted to be included in
     only one such component plan.

          With respect to Plan Years beginning after December 31, 1986, if an
     eligible Highly Compensated Employee is subject to the family aggregation
     rules of Section 414(q)(6) of the Code (as described in the third paragraph
     of the Highly Compensated Employee definition in Section 3.5) because such
     person is either a 5-percent owner (described in the Highly Compensated
     Employee definition) or a Highly Compensated Employee in the group
     consisting of the ten Highly Compensated Employees paid the greatest
     compensation (as described in the Highly Compensated Employee definition),
     the combined actual deferral ratio of the family group (which is treated as
     one Highly Compensated Employee) shall be determined by combining the
     Compensation, as well as the applicable Contributions (described above)
     which are allocated to the Employer Nonforfeitable Contributions Account of
     all such eligible family members described in this sentence. The
     Compensation, as well as the applicable Contributions (described above)
     allocated to the Employer Nonforfeitable Contributions Accounts of all
     eligible family members, are disregarded for purposes of determining the
     ADP of the group of Non-Highly Compensated Employees. If any eligible
     Employee is required to be aggregated as a member of more than one family
     group, all eligible Employees who are members of those family groups that
     include such Employee are aggregated as one family group in accordance with
     the preceding provisions of this paragraph.

          (i)  Excess Employer Contributions Over ADP Limits:
               ---------------------------------------------

               (i)  Distribution of Excess Employer Contributions:  In the event
                    ---------------------------------------------
          that with respect to any Plan Year, the aggregate amount of Employer
          Contributions (taken into account in computing the actual deferral
          percentage of Highly Compensated Employees for the Plan Year) exceeds
          the maximum amount of such Employer Contributions permitted under the
          actual deferral percentage tests set out above, then (to the extent
          that another means of satisfying the ADP test is not implemented by
          the Committee), within two and one-half months from the end of the
          Plan Year or as soon as practicable, but not later than the end of the
          Plan Year immediately following the Plan Year to which any such excess
          Employer Contributions pertain, such excess (plus allocable income or
          loss) shall be distributed to Highly Compensated Employees, as
          provided below. In lieu of distribution of excess Contributions,
          within twelve (12) months after the end of the Plan Year, an Employer
          may make Qualified Non-Elective Contributions on behalf of Non-Highly
          Compensated Employees pursuant to Section 3.4(d) in an amount
          sufficient to satisfy the ADP test for the Plan Year.

               For Plan Years beginning prior to January 1, 1997, the amount of
          such excess Employer Contributions for a Highly Compensated Employee
          for a Plan Year shall be determined by the following leveling method,
          under which the actual deferral ratio of the Highly Compensated
          Employee with the highest actual deferral ratio is reduced to the
          extent required to (i) enable the Plan to satisfy the actual deferral
          percentage test set out above, or (ii) cause such Highly Compensated
          Employee's actual deferral ratio to equal the ratio of the Highly
          Compensated Employee with the next highest actual deferral ratio. This
          process shall be repeated until the Plan satisfies the actual deferral
          percentage test. For Plan Years beginning on and after January 1,
          1997, the amount of such excess contributions for a Highly Compensated
          Employee for a Plan Year shall be determined by the following leveling
          method, under which Elective Contributions of the Highly Compensated
          Employee with the largest dollar amount of Elective Contributions is
          reduced to the extent required to (i) enable the Plan to satisfy the
          ADP test set out above, or (ii) cause such Highly Compensated
          Employee's Elective Contribution amount for the Plan Year to equal the
          Elective Contribution amount of the Highly Compensated Employee with
          the next largest dollar amount of Elective Contributions for the Plan
          Year. This process shall be repeated until the Plan satisfies the ADP
          test. This correction method shall be performed in accordance with
          Section 401(k)(8)(c) of the Code.

               For each Highly Compensated Employee, the amount of such excess
          Employer Contributions is equal to the applicable Contributions

                                    III-13
<PAGE>

          that were allocated to such Employee's Employer Nonforfeitable
          Contributions Account and taken into account in computing his actual
          deferral ratio (determined prior to the application of this and the
          immediately preceding sentence), minus the amount determined by
          multiplying such Employee's actual deferral ratio (determined after
          application of this and the immediately preceding sentence) by his
          Compensation used in determining such ratio.

               For Plan Years beginning prior to January 1, 1997, any such
          excess Employer Contributions shall be allocated to Participants who
          are subject to the family member aggregation rules of Section
          414(q)(6) of the Code (described in the third paragraph of the Highly
          Compensated Employee definition) in the manner prescribed under
          Section 1.401(k)-1(f)(5) of the income tax regulations. Any such
          excess Employer Contributions (including any amounts that are
          recharacterized under applicable provisions of the Plan) shall be
          treated as annual additions under Section 4.3 of the Plan. In no event
          shall the amount of such excess Employer Contributions to be
          recharacterized for a Plan Year with respect to any Highly Compensated
          Employee exceed the amount of Employer Contributions made on behalf of
          such Highly Compensated Employee for such Plan Year.

               For purposes of this subsection, in accordance with Section
          1.401(k)-1(f)(4)(ii)(C) of the income tax regulations, income or loss
          that is allocable to excess Employer Contributions (described above)
          for the Plan Year shall be the income or loss allocable to the
          Participant's Employer Nonforfeitable Contributions Account (to the
          extent attributable to applicable Contributions (described above) used
          in the ADP test), multiplied by a fraction. The numerator of the
          fraction is the Participant's excess Employer Contributions for the
          Plan Year. The denominator is the balance of the Participant's
          Employer Nonforfeitable Contributions Account (to the extent
          attributable to applicable Contributions (described above) used in the
          ADP test), as of the beginning of that Plan Year, plus the applicable
          Contributions (described above) allocated to his Employer
          Nonforfeitable Contributions Account for the Plan Year. No income or
          loss will be allocated for the gap period between the end of the Plan
          Year to the date of distribution for Plan Years beginning on or after
          January 1, 1992 and, with respect to Plan Years beginning before such
          date, income or loss shall be allocated in accordance with the
          applicable income tax regulations and Plan document as then in effect.

               Excess Employer Contributions (and any income allocable thereto)
          shall be distributed from the portion of an Employer Nonforfeitable
          Contributions Account attributable to the Contributions used in the
          ADP test. If the Plan has Qualified Matching Contributions ("QMC"),

                                    III-14
<PAGE>

          distribution of Elective Contributions (plus earnings) and QMC (plus
          earnings) shall be made in proportion to the Participant's Elective
          Contributions and QMC (to the extent used in the ADP test) for the
          Plan Year, unless the Code permits and the committee elects otherwise.
          In addition, to the extent that such excess Employer Contributions are
          attributable to Elective Contributions (and any income allocable
          thereto) which amounts are distributed to the Participant pursuant to
          the preceding provisions of this subsection, Matching Contributions
          (and any income allocable thereto determined in the same manner as for
          other contributions) will be appropriately reduced and the reduced
          Matching Contributions (and any income allocable thereto) shall be
          applied as forfeitures pursuant to Section 4.6. Such reduction shall
          be made first by reduction of Matching Contributions allocated to the
          Participant's Employer Nonforfeitable Contributions Account, and, if
          necessary, next by reduction of Matching Contributions allocated to
          the Participant's Employer Contributions Account. The provisions of
          this paragraph (which provide for reduction of Matching Contributions
          made with respect to excess Elective Contributions which are
          distributed hereunder) are intended to comply with the requirements of
          Sections 401(a), 401(k), 401(m) and 411 of the Code. To the extent
          that any provision of this paragraph is inconsistent with the
          preceding sentence, such provision shall be deemed to be inoperative
          and the plan shall be operated in a manner that complies with the
          requirements of the immediately preceding sentence.

               (ii)   Recharacterization of Excess Employer Contributions:
                      ---------------------------------------------------
          Recharacterization of excess Employer Contributions in accordance with
          provisions of this paragraph shall be permitted from time to time as
          determined by the Committee with respect to any Plan Year in which
          Employee Voluntary Contributions are permitted under the Plan.  In the
          event that such recharacterization is permitted, the opportunity to
          elect to recharacterize excess Employer Contributions shall be
          announced and made available to all affected Participants on a uniform
          basis.  If a determination is made to permit recharacterization,
          pursuant to uniformly applied nondiscriminatory rules which shall be
          established from time to time by the Committee, and subject to the
          provisions of this paragraph, following a Participant's receipt of
          written notification of excess Employer Contributions allocable
          thereto, such Participant may elect (at such time and in such manner
          as shall be prescribed under non-discriminatory rules established from
          time to time by the Committee) whether or not all or any portion of
          such excess Employer Contributions shall be recharacterized as after-
          tax Employee Voluntary Contributions; provided, however, that the
          Committee may effect the recharacterization of a Participant's excess
          Employer Contributions without such Participant's election or consent
          if the Committee determines, in its sole discretion, that it is not
          feasible

                                    III-15
<PAGE>

          under the circumstances to obtain the Participant's election and that
          it is necessary or desirable to promptly effect such
          recharacterization in order to ensure compliance with plan
          qualification requirements. The amount of excess Employer
          Contributions that may be recharacterized with respect to an affected
          Participant for a Plan Year shall be reduced by any excess deferrals
          that were previously distributed to such Participant with respect to
          his taxable year ending with or within such Plan Year.

               Recharacterized amounts shall remain nonforfeitable and, except
          as provided in regulations issued under Section 401(k) of the Code,
          shall be treated as Employee Contributions for purposes of Section
          401(a)(4) of the Code and Section 1.401(k)-1(b) of the income tax
          regulations (including the continued application of the same limits on
          distributions that apply to Elective Contributions), however, for all
          other purposes, such amounts shall be treated as Elective
          Contributions. Elective Contributions shall be reduced by the amount
          recharacterized and related earnings. Notwithstanding any other
          provision of this subsection to the contrary, recharacterization of
          excess Employer Contributions allocable to a Participant shall not be
          permitted to the extent that such amount, in combination with any
          other Employee Contributions made by the affected Participant, would
          exceed any limit under the Plan affecting Employee Contributions. If
          less than all such excess Employer Contributions are recharacterized,
          the amount that must otherwise be distributed under the Plan in order
          to correct such excess shall be reduced by the amount recharacterized
          and related earnings. Earnings related to any recharacterized amount
          shall not be treated as a recharacterized amount.

               Recharacterization must occur no later than two and one-half
          months after the last day of the Plan Year in which such excess
          Employer Contributions arose, and shall be deemed to occur no earlier
          than the date that the last Highly Compensated Employee is informed
          (by the Committee) in writing of the amount recharacterized and the
          consequences thereof. Recharacterized amounts will be taxable to the
          Participant for the Participant's tax year in which the Participant
          would have received them in cash.

          (j)  Actual Contribution Percentage Test:  The actual contribution
               -----------------------------------
     percentage ("ACP"), as determined for a Plan Year pursuant to this
     subsection, for all eligible Highly Compensated Employees shall not exceed
     the greater of:

               (i)   the actual contribution percentage for the group of all
          eligible Non-Highly Compensated Employees multiplied by 1.25, or

               (ii)  the actual contribution percentage of the group of all
          eligible Non-Highly Compensated Employees multiplied by 2.0; provided,

                                    III-16
<PAGE>

          however, that the actual contribution percentage for the group of
          eligible Highly Compensated Employees may not exceed the actual
          contribution percentage of the group of all eligible Non-Highly
          Compensated Employees, by more than two percentage points (2%).

     Unless otherwise elected by the Employer, the relationship of the ACP for
     all eligible Highly Compensated Employees for a specific Plan Year shall be
     determined with respect to the ACP for all eligible Non-Highly Compensated
     Employees for the Plan Year preceding such Plan Year. For Plan Years
     commencing after December 31, 1986, the provisions of Section 401(m) of the
     Code and Section 1.401(m)-1 of the income tax regulations are hereby
     incorporated into the Plan for all purposes. In addition, for Plan Years
     beginning after December 31, 1988, if any Highly Compensated Employee is
     eligible to authorize Elective Contributions under the Plan and to have
     Matching Contributions allocated with respect thereto, or if such Highly
     Compensated Employee is eligible to make elective contributions (described
     in Section 402(g)(3) of the Code) under any other cash or deferred
     arrangement (described in Section 401(k) of the Code) and/or to make
     employee contributions (described in Section 401(m) of the Code) or to
     receive matching contributions (described in Section 401(m)(4)(A) of the
     Code) under any other qualified plan of an Employer and/or any Affiliated
     Employer regardless of whether such plan contains a cash or deferred
     arrangement, the disparities between the actual contribution percentages of
     the respective groups of eligible Highly Compensated Employees and Non-
     Highly Compensated Employees shall be reduced as described in Section
     1.401(m)-2 of the income tax regulations and subsequent provisions of this
     subsection.

          Subject to the limitations set forth below, the actual contribution
     percentage for a specified group of eligible Employees for a Plan Year
     shall be the average of the actual contribution ratios (calculated
     separately for each Employee in such group) of the sum of any (i) Employer
     Matching Contributions allocated to the Employee's Employer Contributions
     Account for the Plan Year, (ii) Employee Voluntary Contributions, including
     any amounts recharacterized as Employee Voluntary Contributions and
     allocated to the Employee's Employee Account, and (iii) to the extent taken
     into account under Section 1.401(m)-1(b)(5) of the income tax regulations
     and this subsection, any Elective Contributions, Qualified Non-Elective
     Contributions, and Profit Sharing Contributions allocated to the Employee's
     Employer Nonforfeitable Contributions Account for such Plan Year, to the
     Employee's Compensation (defined below) for the Plan Year. Notwithstanding
     anything in the preceding sentence to the contrary, the ACP described in
     the preceding sentence shall not include Matching Contributions that are
     forfeited either to correct excess aggregate contributions or because the
     contributions to which they relate are excess deferrals, excess
     contributions or excess aggregate contributions. To the extent that any
     Contribution is required to satisfy the ADP test set forth above in this
     Section, it may not be used to satisfy the ACP test. For the purposes of
     performing the ACP test, Compensation shall mean all remuneration:

                                    III-17
<PAGE>

               (i)   that is (a) received during the Plan Year by the eligible
          Employee from an Employer and is required to be reported as wages on
          the eligible Employee's form W-2 (or its successor) for federal income
          tax withholding purposes (or, in the case of a nonresident alien
          employee, is the type of income that would be required to be reported
          on form W-2 if such employee were subject to such reporting
          requirements), but determined without regard to any rules that limit
          the remuneration included in wages based on the nature or location of
          the employment or the services performed (such as the exception for
          agricultural labor in Section 3401(a)(2) of the Code), plus (b) any
          reduction under a compensation deferral agreement under (1) a plan
          described in Section 401(k) or 408(k) of the Code, (2) an annuity
          described in Section 403(b) of the Code or (3) an election under a
          cafeteria plan described in Section 125 of the Code,

               (ii)  that subject to clause (iv) below, is actually paid to or
          is includible (within the meaning of Section 1.415-2(d)(3) and (4) of
          the income tax regulations) in the gross income of the eligible
          Employee within the relevant Plan Year, or would have been so paid or
          includible but for a reduction described in clause (i) immediately
          above,

               (iii) that does not exceed (A) for Plan Years beginning on or
          after January 1, 1989 and before January 1, 1994, $200,000; and (B)
          for Plan Years beginning on or after January 1, 1994, $150,000 (as
          such dollar amounts are adjusted at such time and in such manner as
          may be prescribed in Section 401(a)(17)(B) of the Code), and

               (iv)  that is received by the eligible Employee during the entire
          Plan Year and not only while he is a Participant.

     For the purposes of computing the actual contribution percentage ratios,
     Elective Contributions shall include excess elective deferrals described in
     Section 3.2 and any Elective Contributions that are not taken into account
     in the actual deferral percentage test, provided that the actual deferral
     percentage test is satisfied both with and without exclusion of these
     Elective Contributions.  Any Qualified Non-Elective Contributions and any
     Profit Sharing Contributions allocated to the Participant's Employer
     Nonforfeitable Contributions Account, as provided above, shall be taken
     into account for purposes of the actual contribution percentage test to the
     extent that such amounts are not needed to pass the actual deferral
     percentage test. With respect to Plan Years commencing after December 31,
     1988, such actual contribution ratios of each eligible Employee and the
     actual contribution percentage of each group shall be calculated to the
     nearest one-hundredth of one percent of the eligible Employee's
     Compensation.  The actual contribution ratio of an eligible Employee is
     zero if no Contributions which are used in computing actual contribution
     ratios are allocated on behalf of such Employee.

                                    III-18

          If an Employer and any Affiliated Employer, individually or
     collectively, maintain two or more plans that are treated as a single plan
     for purposes of Section 401(a)(4) or 410(b) of the Code (other than Section
     410(b)(2)(A)(ii) of the Code as in effect for Plan Years which began after
     December 31, 1988), all employee and matching contributions described in
     Section 1.401(m)-1(f) of the Proposed income tax regulations (or any
     successor thereto) are to be treated as made under a single plan for
     purposes of this Section and Sections 401(a)(4), 401(k) and 410(b) of the
     Code. For Plan Years beginning after December 31, 1989, plans may be
     aggregated under the preceding provisions of this paragraph only if they
     have the same Plan Year. With respect to Plan Years beginning after
     December 31, 1986, if any Highly Compensated Employee is a participant
     under two or more plans of an Employer or any Affiliated Employer which are
     subject to Section 401(m) of the Code, for purposes of determining the
     actual contribution ratio with respect to such Highly Compensated Employee,
     all employee and/or matching contributions described in Section 1.401(m)-
     1(f) of the Proposed income tax regulations (or any successor thereto) made
     under such plans must be aggregated. For Plan Years beginning after 1988,
     contributions and allocations under an employee stock ownership plan
     described in Section 4975(e)(7) of the Code may not be combined with
     contributions or allocations under any plan not described in Section
     4975(e)(7) of the Code.

          With respect to Plan Years beginning prior to January 1, 1992, the
     Plan or, if the Plan is aggregated with another plan pursuant to the
     previous paragraph, such aggregated Plan may, in the discretion of the
     Committee, be restructured (in accordance with Sections 1.401(m)-1(g)(5),
     1.401(a)(4)-1(c)(8)(iii) and 1.401(a)(4)-9(c) of the income tax regulations
     into two or more component plans for purposes of determining whether the
     Plan or aggregated Plan satisfies Section 401(a)(4) of the Code and the
     actual contribution percentage test set forth above. If each of the
     component plans of the Plan or aggregated Plan satisfies all of the
     requirements of Sections 401(a)(4) and 410(b) of the Code as if it were a
     separate Plan or aggregated Plan, then the Plan or aggregated Plan is
     treated as satisfying Section 401(a)(4) of the Code. If the Plan or
     aggregated Plan is restructured into component plans for purposes of
     testing for compliance with Section 401(a)(4) of the Code and the actual
     contribution percentage test, each component plan resulting from such
     restructuring shall consist of all the allocations, accruals, and other
     benefits, rights and features provided to a group of Employees under the
     Plan or aggregated Plan. Each Employee is permitted to be included in only
     one such component plan.

          With respect to Plan Years beginning after December 31, 1986, if an
     eligible Highly Compensated Employee is subject to the family aggregation
     rules of Section 414(q)(6) of the Code (described in the third paragraph of
     the Highly Compensated Employee definition in Article I) because such
     person is either a 5-percent owner (as described in the Highly Compensated
     Employee definition) or a Highly Compensated Employee in the group
     consisting of the ten Highly Compensated Employees paid the greatest
     compensation (as described in the Highly Compensated Employee definition),
     the combined actual contribution ratio of the family group (which is
     treated as one Highly

                                    III-19
<PAGE>

     Compensated Employee) shall be determined by combining the Compensation, as
     well as the applicable Contributions (described above) which are allocated
     to the appropriate Accounts of all eligible family members described in
     this sentence. The Compensation, as well as the applicable Contributions
     (described above) which are allocated to the appropriate Accounts of all
     eligible family members are disregarded for purposes of determining the ACP
     of the group of Non-Highly Compensated Employees. If any eligible Employee
     is required to be aggregated as a member of more than one family group, all
     eligible Employees who are members of those family groups that include that
     Employee shall be aggregated as one family group in accordance with the
     preceding provisions of this paragraph.

          (k)  Prohibited Multiple Use of 2.0/2% Alternative Limits for the ADP
               ----------------------------------------------------------------
     and ACP Tests: Any disparity between the actual deferral percentage or
     -------------
     actual contribution percentage of the respective groups of Highly
     Compensated Employees and Non-Highly Compensated Employees shall be reduced
     as described in Section 1.401(m)-2 of the income tax regulations (or any
     successor regulations). Without limiting the scope of the immediately
     preceding sentence, any multiple use of the alternative method of
     compliance with the ADP and ACP tests (i.e., the 2.0/2% alternative limit
     which is described in clauses (ii) and (iv) below and in Sections
     401(k)(3)(A)(ii)(II) and 401(m)(2)(A)(ii) of the Code) shall be determined
     and corrected, as appropriate, in accordance with the provisions of this
     subsection.

          Multiple use of such alternative limitation shall occur if the sum of
     (a) the actual deferral percentage of the entire group of eligible Highly
     Compensated Employees under the Plan or any other cash or deferred
     arrangement (described in Section 401(k) of the Code) of an Employer or an
     Affiliated Employer and (b) the actual contribution percentage of the
     entire group of eligible Highly Compensated Employees under the Plan or any
     other qualified plan of an Employer or an Affiliated Employer that is
     subject to Section 401(m) of the Code, exceeds the greater of:

               (i)   125 percent of the greater of (1) the actual
                                        -------
          deferral percentage of the group of Non-Highly Compensated
          Employees eligible under the Plan (or other arrangement of
          an Employer or Affiliated Employer that is subject to
          Section 401(k) of the Code) for the Plan Year, or (2) the
          actual contribution percentage of the group of Non-Highly
          Compensated Employees under the Plan (or other plan of an
          Employer or Affiliated Employer that is subject to Section
          401(m) of the Code) for the Plan Year beginning with the
          Plan Year of the Plan (or other arrangement that is subject
          to Section 401(k) of the Code), plus

               (ii)  the number two (2) plus the lesser of clause (1)
                                                 ------
          or (2) of (i) above; provided, however, in no event shall
          the amount computed under this (ii) exceed 200 percent of
          the lesser of clause (1) or (2) of (i) above; or
                                                        --

                               III-20
<PAGE>

               (iii) 125 percent of the lesser of (1) the actual
                                        ------
          deferral percentage of the group of Non-Highly Compensated
          Employees eligible under the Plan (or other arrangement of
          an Employer or Affiliated Employer that is subject to
          Section 401(k) of the Code) for the Plan Year, or (2) the
          actual contribution percentage of the group of Non-Highly
          Compensated Employees under the Plan (or other plan of an
          Employer or Affiliated Employer that is subject to Section
          401(m) of the Code) for the Plan Year beginning with the
          Plan Year of the Plan (or other arrangement that is subject
          to Section 401(k) of the Code), plus

               (iv) the number two (2) plus the greater of clause (1)
                                                -------
          or (2) of (iii) above; provided, however, in no event shall
          the amount computed under this (iv) exceed 200 percent of
          the lesser of clause (1) or (2) of (iii) above.

          Notwithstanding the previous paragraph, multiple use of the
     alternative limitation does not occur if (i) the ADP of the group of Highly
     Compensated Employees does not exceed the product of 1.25 multiplied by the
     ADP of the group of Non-Highly Compensated Employees, or (ii) the ACP of
     the group of Highly Compensated Employees does not exceed the product of
     1.25 multiplied by the ACP of the group of Non-Highly Compensated
     Employees.

          The actual deferral percentage and actual contribution percentage of
     the group of eligible Highly Compensated Employees shall be determined
     after the use of all applicable Contributions to meet the actual deferral
     percentage test and after use of all applicable Contributions to meet the
     requirements of the actual contribution percentage test. In addition, the
     actual deferral percentage and the actual contribution percentage of the
     group of eligible Highly Compensated Employees shall be determined after
     any required corrective distribution of excess deferrals, excess Employer
     Contributions or excess aggregate Contributions (described below), and
     after any required recharacterization of excess Employer Contributions,
     without regard to the rules hereunder relating to multiple use of the
     alternative methods of compliance contained in this subsection and Sections
     401(k)(3)(A)(ii)(II) and 401(m)(2)(A)(ii) of the Code.

          If a multiple use of the alternative method of compliance with
     Sections 401(k) and 401(m) occurs, in order to eliminate the multiple use
     of such alternative method of compliance, the amount of reduction to the
     actual deferral percentage of the entire group of eligible Highly
     Compensated Employees under the Plan (and each other arrangement subject to
     Section 401(k) of the Code) shall be calculated in the manner described in
     this Section 3.4(k) of the Plan and Section 1.401(k)-1(f)(2) of the income
     tax regulations. Such required reduction shall be treated as an excess
     contribution under the arrangement subject to Section 401(k) of the Code.
     However, if any excess contribution is recharacterized as an Employee
     Voluntary Contribution, such recharacterized amount shall be treated as an
     excess aggregate Contribution. Instead of reducing the actual deferral
     ratios of Highly Compensated Employees, the Employer may eliminate the

                                    III-21
<PAGE>

     multiple use of the alternative limitation by making Qualified Non-Elective
     Contributions on behalf of Non-Highly Compensated Employees (pursuant to
     Section 3.4(d)) within twelve (12) months after the end of the Plan Year.

          (l)  Excess Aggregate Contributions Over ACP Limits:  In the event
               ----------------------------------------------
     that with respect to any Plan Year, the aggregate amount of applicable
     Contributions taken into account under the actual contributions percentage
     test (set forth above) on behalf of Highly Compensated Employees exceeds
     the maximum amount of such Contributions permitted under the actual
     contribution percentage test set out above (determined by reducing such
     Contributions made on behalf of Highly Compensated Employees in order of
     actual contribution percentages beginning with the highest of such
     percentages), then, within two and one-half months from the end of the Plan
     Year or as soon as practicable, but not later than the end of the Plan Year
     immediately following the Plan Year to which any such excess aggregate
     Contributions pertain, as described below, such excess (plus allocable
     income loss) shall be forfeited, if forfeitable, or distributed to Highly
     Compensated Employees on the basis of the respective portions of such
     excess aggregate Contributions attributable to each of the Highly
     Compensated Employees as provided below. In lieu of forfeiture or
     distribution of such excess aggregate contributions, within twelve (12)
     months after the end of the Plan Year, the Employer may make Qualified Non-
     Elective Contributions on behalf of Non-Highly Compensated Employees
     pursuant to Section 3.4(d) in an amount sufficient to satisfy the ACP test
     for the Plan Year.

          For Plan Years beginning prior to January 1, 1997, the amount of such
     excess aggregate Contributions for a Highly Compensated Employee for a Plan
     Year shall be determined by the following leveling method, under which the
     actual contribution ratio of the Highly Compensated Employee with the
     highest actual contribution ratio is reduced to the extent required to (i)
     enable the Plan to satisfy the actual contributions percentage test set out
     above, or (ii) cause such Highly Compensated Employee's actual contribution
     ratio to equal the ratio of the Highly Compensated Employee with the next
     highest actual contribution ratio. This leveling process shall be repeated
     until the Plan satisfies the actual contributions percentage test. For Plan
     Years beginning on and after January 1, 1997, the amount of such excess
     aggregate contributions for a Highly Compensated Employee for a Plan Year
     shall be determined by the leveling method prescribed in Section
     401(m)(6)(C) of the Code beginning with the Highly Compensated Employee who
     has the greatest amount of Employee Voluntary Contributions, Matching
     Contributions and other Contributions allocated to his Account for the Plan
     Year that are taken into account for purposes of the ACP test. This
     leveling process shall be repeated until the Plan satisfies the ACP test.

          For each Highly Compensated Employee, the amount of such excess
     aggregate Contributions is equal to the applicable Contributions (described
     above) that were taken into account in computing his actual contribution
     ratio (determined prior to the application of this and the immediately
     preceding sentence), minus the amount determined by multiplying such
     Employee's actual contribution ratio (determined after application of this
     and the immediately preceding sentence) by his Compensation used in

                                    III-22
<PAGE>

     determining such ratio. For Plan Years beginning prior to January 1, 1997,
     any such excess aggregate Contributions shall be allocated to Participants
     who are subject to the family member aggregation rules of Section 414(q)(6)
     of the Code (described in the third paragraph of the Highly Compensated
     Employee definition) in the manner prescribed under Section 1.401(k)-
     1(f)(5) of the income tax regulations.

          For purposes of this subsection, in accordance with Section 1.401(m)-
     1(e)(3)(ii)(C) of the income tax regulations, income or loss that is
     allocable to excess aggregate Contributions (described above) for the Plan
     Year shall be the income or loss allocable to the applicable Contributions
     (described above) used in the ACP test multiplied by a fraction. The
     numerator of this fraction is the Participant's excess aggregate
     Contributions for the Plan Year. The denominator is the balance of the
     Participant's Account to the extent used in the ACP test as of the
     beginning of the Plan Year, plus the applicable Contributions (described
     above) used in the ACP test for the Plan Year. Income or loss allocable to
     excess aggregate contributions that are recharacterized as after-tax
     Employee Voluntary Contributions is determined as if the recharacterized
     amounts had been distributed as Elective Contributions. No income or loss
     will be allocated for the gap period between the end of the Plan Year and
     the date of distribution for Plan Years beginning on or after January 1,
     1992 and, with respect to Plan Years beginning before such date, income or
     loss shall be allocated in accordance with the income tax regulations and
     Plan document as then in effect.

          The Committee (on or before the fifteenth day of the third month
     following the end of the Plan Year but, in any event, before the end of the
     next Plan Year) shall direct the Trustee to distribute to the Highly
     Compensated Employee having the highest actual contribution ratio, his
     portion of the excess aggregate contributions (and income allocable
     thereto) or, if forfeitable, forfeit such non-vested excess aggregate
     contributions attributable to Matching Contributions (and income allocable
     thereto) pursuant to Section 4.6. This process shall be repeated until the
     ACP test is satisfied, or until the actual contribution ratio of such
     Highly Compensated Employee equals the actual contribution ratio of the
     Highly Compensated Employee having the next highest actual contribution
     ratio. Vested Matching Contributions may not be forfeited to correct excess
     aggregate contributions; provided, however, an otherwise vested Matching
     Contribution may be forfeited if the Elective Contribution to which such
     Matching Contribution relates is an excess contribution (above the ADP
     limits of Section 401(k)(3) of the Code) or an excess deferral (above the
     annual dollar limit of Section 402(g) of the Code). The forfeiture or
     distribution of excess aggregate contributions (and allocable income) shall
     be made in the following order:

          (i)   Distribution of Elective Contributions recharacterized
                as Employee Voluntary Contributions, if any;

          (ii)  Forfeiture of non-vested Matching Contributions, if
                any; and

          (iii) Distribution of vested Matching Contributions, if any.

                                    III-24
<PAGE>

          Forfeitures of excess aggregate contributions (and income allocable
     thereto) shall be administered in accordance with Section 4.6; provided,
     however, if forfeitures are allocated to Participants under Section 4.6, no
     forfeitures may be allocated to a Highly Compensated Employee whose excess
     aggregate contributions were reduced pursuant to the previous paragraph.

          Excess aggregate contributions are still counted as Employer
     Contributions, for purposes of Sections 404 and 415 of the Code, for the
     Plan Year when made, even if distributed from the Plan. In addition,
     forfeitures of excess Matching Contributions to satisfy the ACP test are
     still counted as annual additions under Section 415 of the Code for the
     Plan Year when made on behalf of the applicable Highly Compensated
     Employees from whose Accounts such amounts were forfeited. If forfeitures
     are re-allocated to Participants' Accounts pursuant to Section 4.6, such
     forfeitures are also treated as annual additions under Section 415 of the
     Code on behalf of such Participants for the Plan Year in which such amounts
     are re-allocated.

          (m)  Mandatory Disaggregation of Certain Plans:  Notwithstanding any
               -----------------------------------------
     provision of this Section 3.4 to the contrary, the Plan shall be operated
     in accordance with Section 1.401(k)-1(g)(11) of the income tax regulations
     concerning mandatory disaggregation of certain types of plans. Subject to
     all the requirements of Section 1.401(k)-1(g)(11)(iii) of the income tax
     regulations, the following plans shall be treated as comprising separate
     plans:

               (i)   Plans benefiting collective bargaining unit
                     -------------------------------------------
          employees. A plan that benefits employees who are included
          ---------
          in a unit of employees covered by a collective bargaining
          agreement and employees who are not included in such a
          collective bargaining unit is treated as comprising separate
          plans.

               (ii)  ESOPS and non-ESOPs.  For Plan Years beginning on
                     -------------------
          or after January 1, 1991, the portion of a plan that is an
          employee stock ownership plan described in Section 4975(e)
          or 409 of the Code (an ESOP) and the portion of the plan
          that is not an ESOP are treated as separate plans, except as
          otherwise permitted under Section 54.4975-11(e) of the
          income tax regulations.

               (iii) Plans benefiting employees of qualified separate
                     ------------------------------------------------
          lines of business. If an Employer is treated as operating
          -----------------
          qualified separate lines of business for purposes of Section
          410(b) of the Code, the portion of a plan that benefits
          employees of one qualified separate line of business is
          treated as a separate plan from the portions of the same
          plan that benefit employees of the other qualified separate
          lines of business of the Employer.

                               III-24
<PAGE>

               (iv)  Plans maintained by more than one employer--
                     --------------------------------------------

                         (A)  Multiple employer plans.  If a plan
                              -----------------------
                    benefits employees of more than one Employer and
                    the employees are not included in a unit of
                    employees covered by a collective bargaining
                    agreement (a multiple employer plan), the plan is
                    treated as comprising separate plans each of which
                    is maintained by a separate Employer.

                         (B)  Multiemployer plans.  The portion of a
                              -------------------
                    plan that benefits employees who are included in a
                    collective bargaining unit, the portion of a plan
                    that benefits employees who are included in
                    another collective bargaining unit and the portion
                    of a plan that benefits non-collective bargaining
                    unit employees are all treated as separate plans.
                    Consistent with Section 413(b) of the Code, the
                    portion of a plan that is maintained pursuant to a
                    collective bargaining agreement is treated as a
                    single plan maintained by a single employer that
                    employs all the employees benefiting under the
                    same benefit computation formula and covered
                    pursuant to that collective bargaining agreement.
                    The non-collectively bargained portion of the plan
                    is treated as maintained by one or more employers,
                    depending on whether the non-collective bargaining
                    unit employees who benefit under the plan are
                    employed by one or more employers.

     3.5.  Highly Compensated Employee:  For all purposes of the Plan, "Highly
           ---------------------------
Compensated Employee" shall mean, for Plan Years beginning prior to January 1,
1997, (subject to the subsequent provisions hereof) any Employee, who during the
Plan Year for which the determination is being made (the "determination year")
or during the 12-month period immediately preceding the Plan Year (the "look-
back year"):

          (a)  was at any time a 5-percent owner (as defined in
     Section 416(i)(1) of the Code and Section 7.4),

          (b)  received compensation (described below) from an
     Employer in excess of $75,000 (as adjusted at such time and in
     such manner as may be prescribed under Section 414(q) and Section
     415(d) of the Code,

          (c)  received compensation from an Employer in excess of
     $50,000 (as adjusted at such time and in such manner as may be
     prescribed under Section 414(q) and Section 415(d) of the Code,
     and was in the top-paid group of Employees consisting of the top
     20-percent of the Employees when ranked on the basis of
     compensation paid during such year, excluding, however, for
     purposes of

                               III-25
<PAGE>

     determining the number (but, except for Employees covered by
     collective bargaining agreements described below, not identity)
     of Employees which comprise such top-paid group of Employees, (i)
     any Employee who has not completed six months of service as of
     the end of the current year after aggregating the Employee's
     service for an Employer during the current year and the
     immediately preceding year, (ii) any Employee who normally works
     less than 17-1/2 hours per week for 50% or more of the total
     weeks worked during such year (excluding weeks during which an
     Employee did not work for an Employer), (iii) any Employee who
     normally works during not more than six months during any year
     (an Employee who works on one day during a month is deemed to
     have worked during that month), (iv) any Employee who has not
     attained age 21 as of the end of the applicable year, and (v)
     except to the extent provided in regulations issued under Section
     414(q) of the Code by the appropriate governmental authority, any
     Employee who is included in a unit of Employees covered by an
     agreement which the Secretary of Labor finds to be a collective
     bargaining agreement between Employee representatives and an
     Employer, if at least 90 percent of the Employees of an Employer
     are covered under one or more such collective bargaining
     agreements and the Plan does not cover any Employee who is
     covered by any such collective bargaining agreement.

          (d)  was at any time an officer (within the meaning of
     Section 416(i) of the Code) and received compensation greater
     than 50-percent of the dollar amount in effect under Section
     415(b)(1)(A) of the Code for the calendar year in which the
     determination year or look-back year begins.

     With respect to the exclusions for Employees who normally work less than 17
1/2 hours per week or during not more than six months during any year (as
described in clauses (c)(ii) and (c)(iii), respectively, above), such exclusion
determinations may be made separately with respect to each Employee, or on the
basis of groups of Employees who fall within particular job categories as
established by an Employer on a reasonable and consistent basis. For purposes of
clause (c)(ii) above, an Employer may exclude Employees who are members of a
particular job category if (i) 80% of the positions within that job category are
filled by Employees who normally work less than 17 1/2 hours per week, or (ii)
the median number of hours of service credited to Employees in that job category
during a determination year or look-back year, as the case may be, is less than
or equal to 500. Any Employee who is a non-resident alien who receives no earned
income (within the meaning of Section 911(d)(2) of the Code) from an Employer
which constitutes income from sources within the United States (within the
meaning of Section 861(a)(3) of the Code) shall not be treated as an Employee
for the purpose of determining whether an Employee is a Highly Compensated
Employee or a Non-Highly Compensated Employee.

     An Employee shall not be treated as described in Sections 3.5(a), (b) or
(c) for the determination year unless such Employee is also a member of the
group consisting of the 100 Employees paid the greatest compensation (described
below) during the determination year. For purposes of Section 3.5(d), without
regard to any exclusions applicable for purposes of

                                    III-26
<PAGE>

determining the number of Employees in the top-paid group of Employees, no more
than 50 Employees (or, if lesser, the greater of (i) three Employees who perform
services during the determination or look-back year or (ii) 10% of such
Employees) shall be treated as officers with respect to the determination year
or the look-back year, whichever may be applicable. Provided, however, that if
for either such year the number of officers of an Employer who satisfy the
requirements of Section 3.5(d) (as limited by the first sentence of this
paragraph) exceeds the 50-Employee limitation of the immediately preceding
sentence, then the officers who receive the greatest compensation during the
determination year or look-back year will be considered includible officers;
and, further provided, that if for any such year, no officer of an Employer is
described in Section 3.5(d), the highest paid officer of an Employer for such
year (without regard to the amount of compensation paid to such officer in
relation to the dollar limit of Section 415(c)(1)(A) of the Code for the year)
shall be treated as described in such Section 3.5(d) whether or not such
Employee is also a Highly Compensated Employee on any other basis. An individual
who is a Highly Compensated Employee for the determination year or the look-back
year by reason of being described in two or more of Sections 3.5(a), (b), (c),
or (d) shall not be disregarded in determining whether another individual is a
Highly Compensated Employee. The Committee shall prescribe reasonable and
nondiscriminatory rules which shall be uniformly and consistently applied for
the purposes of (i) rounding calculations incident to determining the number of
Employees in the top-paid group of Employees and (ii) breaking ties among two or
more Employees incident to identifying particular Employees who are in the top-
paid group of Employees, who are among the top-10 Highly Compensated Employees,
or who are among the 100 Employees paid the greatest compensation during the
determination year.

     For Plan Years beginning on and after January 1, 1997, "Highly Compensated
Employee" shall mean (subject to the subsequent provisions hereof) any Employee
who

          (i)  was a 5-percent owner (as defined in Section 416(i)(1) of the
     Code and Section 7.4 of the Plan) at any time during the Plan Year for
     which the determination is being made (the "determination year") or during
     the 12-month period immediately preceding the Plan Year (the "look-back
     year"); or

          (ii) received compensation (described below) from the Employer in
     excess of $80,000 (as adjusted at such time and in such manner as may be
     prescribed under Section 414(q) or Section 415(d) of the Code) during the
     look-back year.

     If the Plan Sponsor so elects for a Plan Year, the group described in
clause (ii) above shall be limited to the top-paid group of Employees consisting
of the top 20-percent of the Employees when ranked on the basis of compensation
paid during the look-back year, determined in the same manner as for Plan Years
beginning prior to January 1, 1997, described above.

     For Plan Years beginning prior to January 1, 1997, if, on any single day
during any determination year or look-back year, an Employee is a member of the
family (described below) of another individual who is (i) a 5-percent owner who
is a current or former Employee or (ii) a Highly Compensated Employee (including
former Employees) in the group consisting of the 10

                                    III-27
<PAGE>

Highly Compensated Employees paid the greatest compensation during the
determination year or the look-back year, then such family member and 5-percent
owner or top-10 Highly Compensated Employee shall be considered to be a single
Employee receiving an amount of compensation and a Plan contribution that is
based on the compensation and Plan contribution attributable to such family
member and the 5-percent owner or top-10 Highly Compensated Employee. For
purposes of the immediately preceding sentence, family members of any Employee
or former Employee include the Employee's or former Employee's spouse and lineal
ascendants or descendants and the spouses of lineal ascendants and descendants.
Family members are subject to the aggregation rule described in the second
preceding sentence whether or not (i) they fall within the categories of
Employees that may be excluded for purposes of determining the number of
Employees in the top-paid group consisting of the top 20-percent of the
Employees when ranked on the basis of compensation (as such top-paid group is
described in Section 3.5(c) above), or (ii) they are Highly Compensated
Employees when considered separately.

     A former Employee who, with respect to an Employer, had a "separation year"
(described below) or a "deemed separation year" (described below) prior to the
determination year will be treated as a Highly Compensated Employee for the
determination year if such former Employee was (i) a Highly Compensated Employee
for such former Employee's separation year or deemed separation year, or (ii) a
Highly Compensated Employee for any determination year ending on or after such
former Employee attained age 55. For purposes of the immediately preceding
sentence, an Employee who performs no services for an Employer during a
determination year (including a leave of absence throughout the determination
year) is treated as a former Employee. A "separation year" is the determination
year during which the Employee separates from service with an Employer;
provided, however, an Employee who performs no services for an Employer during a
determination year will be treated as having separated from service with an
Employer in the year in which such Employee last performed services for an
Employer. An Employee who performs services for an Employer during a
determination year will incur a "deemed separation year" if, in any
determination year which ends prior to such Employee's attainment of age 55, the
Employee receives compensation in an amount less than 50% of the Employee's
average annual compensation for the three consecutive calendar years preceding
such determination year during which the Employee received the greatest amount
of compensation from an Employer; provided, however, an Employee will not be
treated as a Highly Compensated Employee (solely by reason of a deemed
separation in a deemed separation year) if, after such deemed separation and
before the year of the Employee's actual separation, such Employee's
compensation increased sufficiently to permit the Employee to be treated as
having a deemed resumption of employment with respect to a determination year,
as prescribed in regulations issued under Section 414(q) of the Code by the
appropriate governmental authority.

     Former Employees are not counted for purposes of determining the top-paid
group consisting of the top 20-percent of the Employees when ranked on the basis
of compensation (as such top-paid group is described in Section 3.5(c) above).
Furthermore, with respect to the determination year, former Employees are not
included in (i) the group consisting of the 100

                                    III-28
<PAGE>

Employees paid the greatest compensation, or (ii) the group of includible
officers of an Employer, as such groups are described in the second paragraph of
this Section.

     For purposes of this Section, "compensation" shall mean the wages (as
defined in Section 3401(a) of the Code for purposes of income tax withholding at
the source) that are paid (within the meaning of Section 1.415-2(d)(3) and (4)
of the income tax regulations) to the Employee by an Employer during the Plan
Year for services performed and reportable on the Employee's form W-2 (or its
successor), determined without regard to any rules that limit the remuneration
included in wages based on the nature or location of the employment or the
services performed (such as the exception for agricultural labor in Section
3401(a)(2) of the Code), plus any salary reduction contributions to tax-
sheltered annuities under Section 403(b) of the Code, and for Plan Years
beginning prior to January 1, 1998, plus elective or salary reduction
contributions to cafeteria plans under Section 125 of the Code, or to cash or
deferred arrangements under Sections 402(e) and 402(h)(1)(B) of the Code. Only
compensation received by the Employee from an Employer, or deemed to be received
pursuant to the preceding sentence, shall be considered for purposes of this
Section; therefore, compensation shall not be annualized in order to compute an
Employee's compensation in the determination year or the look-back year.

     The rules of Section 414(b), (c), (m), (n) and (o) of the Code shall be
applied before the above provisions of this Section are applied. The rules
described in the immediately preceding sentence do not apply for purposes of
determining who is a 5-percent owner. Notwithstanding any provision hereof to
the contrary, the determination of who is a Highly Compensated Employee shall be
made in accordance with Section 414(q) of the Code and the regulations or other
authority issued thereunder by the appropriate governmental authority.

     In the event that the Committee elects to have one or more of the
provisions of this paragraph apply for purposes of determining the status of an
Employee as a Highly Compensated Employee or a Non-Highly Compensated Employee,
the Committee shall adopt a resolution which shall specifically identify the
provision or provisions of this paragraph which shall apply and the effective
date of such application, and a certified copy of such resolution shall be
attached to the Plan as an exhibit which shall be referenced to this Section and
shall be deemed to be an amendment of the Plan which is incorporated in and made
a part of this Section for all purposes of the Plan. Any provision of this
paragraph which becomes operative by virtue of application of the preceding
sentence shall override or supersede and control over any provision or
provisions of this Section which may be inconsistent with the operative
provision or provisions of this paragraph. Accordingly, to the extent elected by
the Committee in compliance with the requirements of the first sentence of this
paragraph, the following provision or provisions shall apply:

          (x)  To the extent permitted in regulations issued under Section
     414(q) of the Code by the appropriate governmental authority, the look-back
     year calculation for a determination year shall be made on the basis of the
     calendar year ending with or within the applicable determination year (or,
     in the case of a determination year that is shorter than twelve months, the
     calendar year ending with or within the twelve month period ending with the
     end of the applicable

     determination year); provided, however, the computation contemplated
     hereunder shall apply only if the Committee elects, as described above, to
     apply the same computation provisions to all plans, entities and
     arrangements of an Employer which are required to apply the definition of
     Highly Compensated Employee set forth in Section 414(q) of the Code.

          (y)  To the extent permitted in regulations issued under Section
     414(q) of the Code, Leased Employees covered under a qualified money
     purchase pension plan maintained by a leasing organization and not covered
     under a qualified retirement plan of an Employer (including the Plan),
     shall be included for purposes of determining the group of Highly
     Compensated Employees hereunder.

          (z)  To the extent permitted in regulations issued under Section
     414(q) of the Code, the special definition (described in such regulations)
     for purposes of determining whether former Employees who separated from
     service with an Employer prior to January 1, 1987 are Highly Compensated
     Employees shall apply; provided, however, the special definition
     contemplated hereunder shall apply only if the Committee elects, as
     described above, to apply the special definition to all plans, entities and
     arrangements of an Employer which are required to apply the definition of
     Highly Compensated Employee set forth in Section 414(q) of the Code, and
     further, provided that such election to use such special definition may not
     be changed by an Employer without the consent of the Internal Revenue
     Service.

Subject to any governmental approval as may be required under applicable
regulations or other authority issued by the appropriate governmental authority,
any operative provision of this paragraph may be changed by attaching a
certified resolution of the Committee (which resolution shall be attached to the
Plan as an exhibit) which (i) shall identify the provision or provisions of the
paragraph that are to be changed and the effective date of such change, (ii)
shall be referenced to this Section, and (iii) shall be deemed to be an
amendment of the Plan which is incorporated in and made part of this Section for
all purposes of the Plan.

     3.6. Composition of and Deadline for Payment of Employer Contributions:
          -----------------------------------------------------------------
Employer Contributions shall be paid to the Trust Fund in cash or in kind
(including shares of common stock of the Plan Sponsor).

     Any Elective Contributions made pursuant to Compensation Deferral
Agreements for the Plan Year shall be paid to the Trust Fund (in installments
based on an Employer's pay period and in an amount equal to the amount by which
all Participants' Considered Compensation was reduced pursuant to Compensation
Deferral Agreements applicable to the pay period) not later than thirty (30)
days after the end of an Employer's pay period to which such Contributions are
attributable, while all other Contributions of an Employer for each Plan Year
shall be paid to the Trustee in one or more installments as the Committee may
from time to time determine; provided, however, the Contribution may be paid not
later than the time prescribed by law for

                                    III-30
<PAGE>

filing an Employer's federal income tax return (including extensions thereof)
for such Employer's taxable year ending with or within the Plan Year if (i) the
Contribution is treated by the Plan in the same manner that the Plan would treat
a Contribution actually received on the last day of such taxable year and (ii)
either of the following conditions are satisfied: (1) an Employer designates the
Contribution in writing to the Trustee as a payment on account of such taxable
year, or (2) an Employer claims such Contribution as a deduction on its federal
income tax return for such taxable year; and, further provided, that to the
extent required under regulations or other authority prescribed by the
appropriate governmental authority, any Contributions (other than Elective
Contributions) which are to be taken into account for purposes of determining
the actual deferral percentage or actual contribution percentage (defined in
Section 3.4) shall (in addition to the limitations thereon under the Plan with
respect to vesting and withdrawals) be paid to the Trust Fund not later than the
last day of the 12-month period that immediately follows the end of the Plan
Year to which such Contributions pertain. To the extent required under
regulations or other authority prescribed by the appropriate governmental
authority, Matching Contributions which are taken into account for the actual
contribution percentage (defined in Section 3.4) shall similarly be paid to the
Trustee not later than the last day of the 12-month period that immediately
follows the end of the Plan Year to which such Contributions pertain.

     3.7. Return of Contributions for Mistake, Disqualification or Disallowance
          ---------------------------------------------------------------------
of Deduction:  The assets of the Trust Fund shall in no event be paid to or
- ------------
revert to any Employer or be used for any purpose other than the exclusive
benefit of the Participants and their Beneficiaries and the reasonable expenses
of administering the Plan except that:

          (a)  If an Employer makes a Contribution by mistake of fact, such
     mistaken Contribution shall revert and be repaid to an Employer within one
     year after the payment of the Contribution;

          (b)  An Employer's Contribution for each Plan Year is conditioned on
     the Plan's initial qualification under Section 401 of the Code and an
     Employer's Contribution shall revert and be repaid to an Employer within
     one year after the date of denial of the initial qualification of the Plan;
     and

          (c)  An Employer's Contribution is conditioned upon the deductibility
     thereof under Section 404 of the Code and, to the extent the deduction is
     disallowed, the Contribution shall revert and be repaid to an Employer
     within one year after the disallowance of the deduction.

     In any case hereinabove described in clauses (a), (b), or (c) of this
Section, an Employer shall, subject to the limitations set forth below, have
exclusive authority and absolute discretion to determine whether a Contribution,
or any part thereof, shall revert and be repaid to it or shall instead remain a
part of the Trust Fund. The amount which may be repaid to an Employer under
clauses (a) or (c) of this Section may not exceed the excess of (i) the amount
contributed over (ii) the amount that would have been contributed had there not
occurred a mistake of fact or a mistake in determining the deduction. Earnings
attributable to such excess contribution shall not be repaid, and losses
attributable thereto shall reduce the amount which may be returned. If the

                                    III-31
<PAGE>

repayment of the amount attributable to the mistaken Contribution would cause
the balance of any Participant's Account to be reduced to less than the balance
which would have been in the Account had the mistaken amount not been
contributed, then the amount which may be repaid to an Employer shall be limited
so as to avoid such reduction.

     3.8. Qualified Military Service:  Notwithstanding any provision of this
          --------------------------
Plan to the contrary, contributions, benefits and service credit with respect to
qualified military service will be provided in accordance with Section 414(u) of
the Code. To the extent that the Employer chooses to suspend loan payments
during participants' periods of qualified military service, loan payments will
be suspended under this Plan as permitted under Section 414(u) of the Code.

                                 PARTICIPATION

     4.1. Periodic Certification by Employer.  As soon as practicable after such
          ----------------------------------
Contribution is made, each Employer shall certify to the Committee the amount of
any Elective, Matching, Qualified Non-Elective, and/or Profit Sharing
Contribution that it made for the period then ended, the names of its
Participants entitled to share in each type of Contribution, the amount of each
of its Participant's Voluntary Contributions, if any, for such period, the
number of years of Active Service of its Participants, the amount of Considered
Compensation paid to each such Participant for such period, and the amount of
Considered Compensation paid to all its Participants for such period. Such
certification shall be conclusive evidence of such facts.

     4.2. Allocation of Employer Contributions:

          (a)  Elective Contributions:  As of the end of each month to which
               ----------------------
     Elective Contributions apply, Elective Contributions authorized by the
     Participant for such month pursuant to a Compensation Deferral Agreement
     (and permitted under applicable provisions of the Plan to be made by an
     Employer on behalf of the Participant) shall be allocated to the
     Participant's Employer Nonforfeitable Contributions Account.

          (b)  Matching Contributions:  As of the last day of each applicable
               ----------------------
     month, Matching Contributions described in Section 3.4(b) shall be credited
     to the Participant's Employer Contributions Account.

          (c)  Profit Sharing Contributions:  As of the end of the Plan Year
               ----------------------------
     to which any Profit Sharing Contribution applies, the Committee shall
     allocate any Profit Sharing Contribution for the Plan Year to each
     Participant who satisfies the requirements of Section 3.4(c) in the
     proportion that the total Considered Compensation of each such Participant
     for such Plan Year bears to the total Considered Compensation for all such
     Participants for such Plan Year, and shall credit each such Participant's
     proportionate share to the Participant's Employer Nonforfeitable
     Contributions Account and/or Employer Contributions Account, as specified
     in resolutions adopted by the Board and communicated to Participants;
     provided, however, absent such specification, the Committee shall credit
     each Participant's proportionate share to the Participant's Employer
     Contributions Account.

          (d)  Qualified Non-Elective Contributions:  As of the end of the
               ------------------------------------
     Plan Year to which any Qualified Non-Elective Contribution applies, the
     Committee shall allocate any Qualified Non-Elective Contribution for the
     Plan Year to each eligible Participant who satisfies the requirements of
     Section 3.4(d) in the proportion that total Considered Compensation of each
     such Participant for the Plan Year bears to total Considered Compensation
     for all such Participants for such Plan Year, and shall credit each such
     Participant's proportionate share to the Participant's Employer
     Nonforfeitable Contributions Account.

                                     IV-1
<PAGE>

          (e)  Top-Heavy Minimum Contribution:  Notwithstanding any other
               ------------------------------
     provision of the Plan to the contrary, if the Plan is a Top-Heavy Plan
     described in Article VII for the Plan Year, such portion of an Employer's
     Contribution (made pursuant to applicable provisions of Section 3.4(f))
     shall be allocated among an Employer's Participants who are in its employ
     at the end of the Plan Year (including Participants who, except for Section
     7.4(f) of the Plan, may not otherwise be entitled to share in the
     allocation) as may be required to ensure that each such Participant is
     credited with an amount which when added to any other portion of an
     Employer Contribution allocated to his Account will equal the minimum
     allocation required under Section 7.3(c) of the Plan. Any such amount
     allocated hereunder shall be specially allocated pursuant hereto and
     credited to the Participant's Employer Contributions Account.

          (f)  Restoration of Forfeited Amounts:  The Committee shall allocate
               --------------------------------
     any Employer Contribution (made in accordance with applicable provisions of
     Section 3.4(e) to restore an Account in accordance with the requirements of
     Section 4.6) to the Account required to be restored under applicable
     provisions of Section 4.6. The Committee shall temporarily hold any
     Employer Contribution (made in accordance with Section 3.4 to restore an
     Account in accordance with the requirements of Section 6.7) in an
     unallocated distribution account until it can be paid out in accordance
     with the provisions of Section 6.7. Distribution from the unallocated
     distribution account to the appropriate person shall be made as soon as
     practicable.

          If a Participant has been Transferred during a pay period or the Plan
     Year, such Participant shall be entitled to have allocated to his Account a
     portion of an Employer Contribution made by each Employer by whom such
     Participant was employed during such pay period or Plan Year, and such
     Participant's share of each Employer's Contribution shall be computed with
     respect to each such Employer in the manner hereinabove provided.

     4.3. Limitation on Additions to Account:
          ----------------------------------

     Capitalized terms used in this Section which are not otherwise defined in
Article I of the Plan are defined in Section 4.3(d).

          (a)  Participant Covered Solely in This Plan:  This Section 4.3(a)
               ---------------------------------------
     applies only if the Participant does not participate in, and has never
     participated in, another qualified plan, a welfare benefit fund, as defined
     in Section 419(e) of the Code, or an individual medical account, as defined
     in Section 415(l)(2) of the Code, maintained by an Employer, which provides
     an Annual Addition.

               (i)  If the Participant does not participate in, and has never
          participated in another qualified plan, a welfare benefit fund, as
          defined in Section 419(e) of the Code, or an individual medical
          account, as defined in Section 415(l)(2) of the Code, maintained by an
          Employer, the amount of

                                     IV-2
<PAGE>

          Annual Additions which may be credited to the Participant's Account as
          of any allocation date for any Limitation Year will not exceed the
          lesser of (1) the Maximum Permissible Amount or (2) any other
          limitation contained in the Plan. If an Employer Contribution that
          would otherwise be contributed or allocated to the Participant's
          Account would cause the Annual Additions for the Limitation Year to
          exceed the Maximum Permissible Amount, the amount contributed or
          allocated will be reduced so that the Annual Additions for the
          Limitation Year will equal the Maximum Permissible Amount.

               (ii)   Prior to the determination of the Participant's actual
          compensation for a Limitation Year, an Employer may determine the
          Maximum Permissible Amount on the basis of a reasonable estimation of
          the Participant's annual Compensation for such Limitation Year,
          uniformly determined for all Participants similarly situated.

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

               (iv)   Pursuant to Section 1.415-6(b)(6) of the income tax
          regulations, if, as a result of the allocation of forfeitures, a
          reasonable error in estimating a Participant's annual compensation, a
          reasonable error in determining the amount of elective deferrals
          (within the meaning of Section 3.2 of the Plan and Section 402(g)(3)
          of the Code) that may be made with respect to a Participant under the
          limits of Section 415 of the Code, or any other facts and
          circumstances as the Internal Revenue Service determines justify the
          availability of this Section 4.3(a)(iv), there is an Excess Amount
          with respect to a Participant for a Limitation Year, such Excess
          Amount shall be disposed of as follows:

                    (1)  First, if the Participant is in the service of an
               Employer at the end of the Limitation Year, then such Excess
               Amounts in the Participant's Account must not be distributed to
               the Participant, but shall be reallocated to a temporary suspense
               account and shall be reapplied to reduce future Employer
               Contributions under the Plan for such Participant in the next
               Limitation Year, and for each succeeding Limitation Year, if
               necessary.

                    (2)  If after application of Section 4.3(a)(iv)(1) an Excess
               Amount still exists, and the Participant is not in the service of
               an Employer at the end of the Limitation Year, then such Excess
               Amounts in the Participant's Account must not be distributed to
               the

                                     IV-3
<PAGE>

               Participant, but shall be reallocated to a temporary suspense
               account and shall be reapplied to reduce future Employer
               Contributions for all remaining Participants in the next
               Limitation Year and each succeeding Limitation Year if necessary.

                    (3)  If a temporary suspense account is in existence at any
               time during the Limitation Year pursuant to this Section, it will
               not participate in the allocation of the Trust Fund's investment
               gains and losses. If a temporary suspense account is in existence
               at any time during a Limitation Year, all amounts in the suspense
               account must be applied as set forth above before any Employer or
               Employee Contributions may be made to the Plan for that
               Limitation Year. Excess Amounts may not be distributed to
               Participants.

     For Plan Years beginning on and after January 1, 1995, if due to a
reasonable error in determining the amount of Elective Contributions that may be
made within the limits of Section 415 of the Code, in accordance with Section
1.415-6(b)(6) of the income tax regulations, the Plan shall first return any
Employee Voluntary Contributions (and distribute any earnings attributable
thereto) to the extent that the return reduces the Excess Amount, and if after
such return and distribution, an Excess Amount still exists, the Plan shall next
distribute Elective Contributions (and any earnings attributable thereto) to the
extent that such distribution reduces the Excess Amount. Earnings shall be
determined in the same manner as for remedying excess Employer Contributions
under Section 3.4(i) and excess Contributions under Section 3.4(l), as
applicable. Any such amounts returned or distributed shall not be taken into
account for purposes of computing (i) the dollar limit on Elective Contributions
under Section 3.2 of the Plan and Section 402(g) of the Code, (ii) the ADP test
under Section 3.4 of the Plan and Section 401(k)(3) of the Code, and (iii) the
ACP test under Section 3.4 of the Plan and Section 401(m)(2) of the Code.

     (b)  Participant Covered Under Defined Contribution Plan:  This Section
          ---------------------------------------------------
4.3(b) applies if, in addition to the Plan, the Participant is covered under
another qualified plan which is a defined contribution plan, a welfare benefit
fund, as defined in Section 419(e) of the Code, or an individual medical
account, as defined in Section 415(l)(2) of the Code, maintained by an Employer
during any Limitation Year, which provides an Annual Addition during the
Limitation Year.

          (i)  The Annual Additions which may be credited to a Participant's
     Account under the Plan for any such Limitation Year will not exceed the
     lesser of (1) the Maximum Permissible Amount reduced by the Annual
     Additions credited to a Participant's account under the other plans,
     welfare benefit funds and individual medical accounts for the same
     Limitation Year or (2) any other limitation contained in the Plan. If the
     Annual Additions with respect to the Participant under other defined

                                     IV-4
<PAGE>

          contribution plans, welfare benefit funds, and individual medical
          accounts, maintained by an Employer are less than the Maximum
          Permissible Amount and an Employer Contribution that would otherwise
          be contributed or allocated to the Participant's Account under the
          Plan would cause the Annual Additions for the Limitation Year to
          exceed this limitation, the amount contributed or allocated will be
          reduced so that the Annual Additions under all such plans and funds
          for the Limitation Year will equal the Maximum Permissible Amount.  If
          the Annual Additions with respect to the Participant under such other
          defined contribution plans, welfare benefit funds, and individual
          medical accounts, in the aggregate are equal to or greater than the
          Maximum Permissible Amount, no amount will be contributed or allocated
          to the Participant's Account under the Plan for the Limitation Year.

               (ii)  Prior to determining the Participant's actual Compensation
          for the Limitation Year, an Employer may determine the Maximum
          Permissible Amount in the manner described in Section 4.3(a)(ii).

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

               (iv)  Pursuant to Section 1.415-6(b)(6) of the income tax
          regulations, if, as a result of the allocation of forfeitures, a
          reasonable error in estimating a Participant's annual compensation, a
          reasonable error in determining the amount of elective deferrals
          (within the meaning of Section 3.2 of the Plan and Section 402(g)(3)
          of the Code) that may be made with respect to a Participant under the
          limits of Section 415 of the Code, or any other facts and
          circumstances as the Internal Revenue Service determines justify the
          availability of this Section 4.3(b)(iv), a Participant's Annual
          Additions under the Plan and all such other plans result in an Excess
          Amount, such Excess Amount shall be deemed to consist of the Annual
          Additions last allocated, except that Annual Additions attributable to
          a welfare benefit fund will be deemed to have been allocated first
          regardless of the actual allocation date.

               (v)   If an Excess Amount was allocated to a Participant's
          Account on an allocation date of the Plan which coincides with an
          allocation date of another plan, the Excess Amount attributed to the
          Plan will be the product of,

                     (1)  the total Excess Amount allocated as of such date,
               multiplied by

                                     IV-5
<PAGE>

                     (2)  the ratio of (A) the Annual Additions allocated to the
               Participant's Account for the Limitation Year as of such date
               under the Plan, divided by (B) the total Annual Additions
               allocated to the Participant's Account for the Limitation Year as
               of such date under the Plan and all qualified defined
               contribution plans.

               (vi)  Any Excess Amounts attributed to the Plan shall be disposed
          of as provided in Section 4.3(a)(iv).

          If due to a reasonable error in determining the amount of Elective
     Contributions that may be made within the limits of Section 415 of the
     Code, in accordance with Section 1.415-6(b)(6) of the income tax
     regulations, the Plan shall distribute Elective Contributions to the extent
     that such distribution reduces the Excess Amount. Any such amounts
     distributed shall not be taken into account for purposes of computing (i)
     the dollar limit on Elective Contributions under Section 3.2 of the Plan
     and Section 402(g) of the Code, (ii) the ADP test under Section 3.4 of the
     Plan and Section 401(k)(3) of the Code, and (iii) the ACP test under
     Section 3.4 of the Plan and Section 401(m)(2) of the Code.

          (c)  Participant Covered Under Defined Benefit Plan: If an Employer
               ----------------------------------------------
     maintains, or at any time maintained, a qualified defined benefit plan
     covering any Participant of the Plan, the sum of the Participant's Defined
     Benefit Fraction and Defined Contribution Fraction will not exceed 1.0. For
     purposes of this Section 4.3, all defined contribution plans of an Employer
     are to be treated as one defined contribution plan and all defined benefit
     plans of an Employer are to be treated as one defined benefit plan, whether
     or not such plans have been terminated. If the sum of the Defined
     Contribution Fraction and Defined Benefit Plan Fraction exceeds 1.0, the
     rate of accrual of the annual benefit of the defined benefit plan(s) will
     be reduced so that the sum of the fractions will not exceed 1.0. In no
     event will the annual benefit be decreased below the amount of the accrued
     benefit to date. If additional reductions are required for the sum of the
     fractions to equal 1.0, the reductions will then be made to the Annual
     Additions of the defined contribution plans. If the defined benefit plan
     does not contain provisions which correspond to this provision, the Annual
     Addition to the defined contribution plans for the Limitation Year will be
     reduced so that the sum of the fractions will not exceed 1.0.

          (d)  Definitions:  For purposes of this Section 4.3, the following
               -----------
     terms shall be defined as follows:

               (i)  Annual Addition -- With respect to any Participant an Annual
                    ---------------
          Addition shall be the sum, for the Limitation Year, of (1) all
          Employer Contributions allocated to his Account; (2) all forfeitures
          allocated to his Account; and (3) the amount of any nondeductible
          after-tax Participant Voluntary Contributions allocated to his
          Account. Moreover, any Excess Amounts applied under Section 4.3(a)(iv)
          or 4.3(b)(vi) during the Limitation Year to reduce Employer
          Contributions shall be considered

                                     IV-6
<PAGE>

          to be Annual Additions for such Limitation Year. Subject to the
          correction rules of Section 4.3(a)(iv), Contributions do not fail to
          be Annual Additions merely because they are excess deferrals
          (described in Section 3.2(c) of the Plan), excess contributions above
          the ADP limits (described in Section 3.4(h) of the Plan), or excess
          aggregate contributions above the ACP limits (described in Section
          3.4(j) of the Plan); provided, however, excess deferrals which are
          timely distributed by April 15 following the year of deferral to the
          applicable Participant pursuant to Section 3.2(d) of the Plan are not
          Annual Additions.

               Amounts allocated, after March 31, 1984, to an individual medical
          account, as defined in Section 415(1) of the Code, which is part of a
          defined benefit plan maintained by an Employer, are treated as Annual
          Additions to a defined contribution plan. Also, amounts derived from
          contributions paid or accrued after December 31, 1985, in taxable
          years ending after such date, which are attributable to postretirement
          medical benefits allocated to the separate account of a key employee,
          as defined in Section 419A(d)(3) of the Code, under a welfare benefit
          fund, as defined in Section 419(e) of the Code, maintained by an
          Employer, are treated as Annual Additions to a defined contribution
          plan. The Annual Addition for any Limitation Year beginning before
          January 1, 1987 shall not be recomputed to treat all Employee
          Contributions as Annual Additions.

               (ii) Compensation -- For each Limitation Year commencing after
                    ------------
          December 31, 1989, a Participant's wages (as defined in Section
          3401(a) of the Code for purposes of income tax withholding at the
          source) that are paid (within the meaning of Section 1.415-2(d)(3) and
          (4) of the income tax regulations) to the Participant by an Employer
          during the Limitation Year for services performed and reportable on
          the Participant's form W-2 (or its successor), but determined without
          regard to any rules that limit the remuneration included in wages
          based on the nature or location of the employment or the services
          performed (such as the exception for agricultural labor in Section
          3401(a)(2) of the Code). For each Limitation Year commencing prior to
          January 1, 1990, Compensation for purposes of this Section shall be
          defined by reference to Section 1.415-2(d)(1) and (2) of the income
          tax regulations.

               Notwithstanding any contrary provision of this Plan, for Plan
          Years beginning on and after January 1, 1998, Compensation for
          purposes of this Section 4.3 of the Plan shall include (A) any
          elective deferral as described in Section 402(g)(3) of the Code and
          (B) any amount which is contributed or deferred by the Employer at the
          election of the Employee and which is not includable in the gross
          income of the Employee by reason of Section 125 or Section 457 of the
          Code.

                                     IV-7
<PAGE>

               (iii)  Defined Benefit Fraction -- A fraction, the numerator of
                      ------------------------
          which is the sum of the Participant's Projected Annual Benefits under
          all the defined benefit plans (whether or not terminated) maintained
          by an Employer and, subject to application of Section 416(h) of the
          Code and Article VII of the Plan relating to Top-Heavy Plans, the
          denominator of which is the lesser of 125 percent of the dollar
          limitation in effect for the Limitation Year under Section
          415(b)(1)(A) and Section 415(d) of the Code or 140 percent of the
          Highest Average Compensation, including any adjustments under Section
          415(b) of the Code.

               Notwithstanding the above, if the Participant was a Participant
          as of the first day of the first Limitation Year beginning after
          December 31, 1986, in one or more defined benefit plans maintained by
          an Employer which were in existence on May 6, 1986, the denominator of
          this fraction will not be less than 125 percent of the sum of the
          annual benefits under such plans which the Participant had accrued as
          of the close of the last Limitation Year beginning before January 1,
          1987, disregarding any changes in the terms and conditions of the Plan
          after May 5, 1986. The preceding sentence applies only if the defined
          benefit plans individually and in the aggregate satisfied the
          requirements of Section 415 of the Code and regulations or other
          authority issued thereunder by the appropriate governmental authority
          for all Limitation Years beginning before January 1, 1987.

               (iv) Defined Contribution Fraction -- A fraction, the numerator
                    -----------------------------
          of which is the sum of the Annual Additions to the Participant's
          account under all the defined contribution plans (whether or not
          terminated) maintained by an Employer for the current and all prior
          Limitation Years (including the Annual Additions attributable to the
          Participant's nondeductible employee contributions to all defined
          benefit plans, whether or not terminated, maintained by an Employer,
          and the Annual Additions to all welfare benefit funds as defined in
          Section 419(e) of the Code, and individual medical accounts, as
          defined in Section 415(l)(2) of the Code, maintained by an Employer),
          and the denominator of which is the sum of the Maximum Aggregate
          Amounts for the current and all prior Limitation Years of service with
          an Employer (regardless of whether a defined contribution plan was
          maintained by an Employer). Subject to application of Section 416(h)
          of the Code and Article VII of the Plan relating to Top-Heavy Plans,
          the Maximum Aggregate Amount in any Limitation Year is the lesser of
          125 percent of the dollar limitation in effect under Section
          415(c)(1)(A) of the Code or 35 percent of the Participant's
          Compensation for such year.

               If the Participant was a Participant as of the end of the first
          day of the first Limitation Year beginning after December 31, 1986, in
          one or

                                     IV-8
<PAGE>

          more defined contribution plans maintained by an Employer which were
          in existence on May 6, 1986, the numerator of this fraction will be
          adjusted if the sum of this fraction and the Defined Benefit Fraction
          would otherwise exceed 1.0 under the terms of the Plan.  Under the
          adjustment, an amount equal to the product of (1) the excess of the
          sum of the fractions over 1.0 times (2) the denominator of this
          fraction, will be permanently subtracted from the numerator of this
          fraction.  The adjustment is calculated using the fractions as they
          would be computed as of the end of the last Limitation Year beginning
          before January 1, 1987, and disregarding any changes in the terms and
          conditions of the Plan made after May 5, 1986, but using the Section
          415 limitation 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 any Employee
          Contributions as Annual Additions.

               (v)    Employer -- An Employer that adopts the Plan. In the case
                      --------
          of a group of Employers which constitutes a controlled group of
          corporations (as defined in Section 414(b) of the Code as modified by
          Section 415(h) of the Code) or which constitutes trades or businesses
          (whether or not incorporated) which are under common control (as
          defined in Section 414(c) as modified by Section 415(h) of the Code)
          or all members of an affiliated service group (as defined in Section
          414(m) of the Code) or any other entity required to be aggregated with
          an Employer pursuant to regulations under Section 414(o) of the Code,
          all such Employers shall be considered a single Employer for purposes
          of applying the limitations of this Section 4.3.

               (vi)   Excess Amount -- The excess of the Annual Additions
                      -------------
          credited to the Participant's Account for the Limitation Year over the
          Maximum Permissible Amount.

               (vii)  Highest Average Compensation -- The average compensation
                      ----------------------------
          for the three consecutive years of service with an Employer that
          produces the highest average. A year of service with an Employer is
          the 12-consecutive-month period which corresponds with the Limitation
          Year.

               (viii) Limitation Year -- The 12-consecutive-month period which
                      ---------------
          begins on the first day of the Plan Year and anniversaries thereof.
          All qualified plans maintained by an Employer must use the same
          Limitation Year. If the Limitation Year is amended to a different 12-
          consecutive-month period, the new Limitation Year must begin on a date
          within the Limitation Year in which the amendment is made.

                                     IV-9
<PAGE>

               (ix) Maximum Permissible Amount -- The Maximum Permissible Amount
                    --------------------------
          with respect to any Participant shall be the lesser of (1) $30,000
          (or, if greater, one-fourth of the defined benefit dollar limitation
          set forth in Section 415(b)(1) of the Code as in effect for the
          Limitation Year) or (2) except as otherwise provided below, 25 percent
          of his actual Compensation for the Limitation Year. Effective on
          January 1 of the calendar year prescribed in Section 415(d) of the
          Code and each January 1 thereafter, the $30,000 limitation above will
          be automatically adjusted to the new dollar limitation determined by
          the Commissioner of Internal Revenue for that calendar year in
          accordance with applicable provisions of Sections 415(b), 415(c) and
          415(d) of the Code. The new limitation will apply to Limitation Years
          ending within the calendar year of the date of the adjustment. The 25
          percent of actual Compensation limitation referred to above shall not
          apply to any contribution for medical benefits (within the meaning of
          Section 401(h) or Section 419A(f)(2) of the Code) after separation
          from service which is otherwise treated as an Annual Addition, or to
          any other amount otherwise treated as an Annual Addition under Section
          415(1)(1) or Section 419A(d)(2) of the Code.

               If a short Limitation Year is created because of an amendment
          changing the limitation to a different 12-consecutive-month period,
          the Maximum Permissible Amount shall not exceed the defined
          contribution dollar limitation for the short Limitation Year
          determined as follows: the dollar limitation in effect for the
          calendar year in which the short Limitation Year ends will be
          multiplied by a fraction, the numerator of which is the number of
          months in the short Limitation Year, and the denominator of which is
          12.

               (x)  Projected Annual Benefit -- A Participant's annual
                    ------------------------
          retirement benefit (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) to which the Participant would
          be entitled under the respective plan, assuming that the Participant
          will continue employment until the later of current age or normal
          retirement age under the respective plan, and that the participant's
          compensation for the current Limitation Year and all other relevant
          factors used to determine benefits under the respective plan will
          remain constant for all future Limitation Years.

     4.4. Periodic Valuation of Trust Fund:  Subject to Sections 4.5 and 4.10,
          --------------------------------
as of the last day of each Plan Year (or such other date or dates as may be
prescribed by the Committee), the Trustee shall determine the amount of income
earned or loss incurred by the Trust Fund during the period since the last
Valuation Date, taking into account estimated expenses, and shall provide such
information to the Committee.  The Committee shall then allocate the income or
loss among the Participants based upon the daily compound interest earned or
lost by each

                                     IV-10
<PAGE>

Participant's Account during the period. Additionally, as of the end of the Plan
Year, the Trustee shall revalue the Trust Fund at fair market value, determining
appreciation or depreciation, if any, and shall determine the exact income or
loss of the Trust Fund, taking into account any understatement or overstatement
of income because the estimated investment fees and other expenses differed from
the actual expenses for the Plan Year. The Trustee then shall provide such
information to the Committee. The Committee shall then allocate all such
appreciation or depreciation and all such understatement or overstatement of
income or loss among the Participants in the same ratio that the income or loss
was allocated to each Participant's Account during the Plan Year as compared to
the income allocated to all Participants' Accounts during the Plan Year who are
Participants of the Plan on the last day of the Plan Year, crediting each such
Participant's individual accounts and subaccounts with their proportionate share
based upon the income or loss allocated to such accounts for the Plan Year, as
compared to the income or loss allocated to the whole of the Participant's
Account for that Plan Year.

     Prior to the allocations described in this Section and subject to Section
4.10, Account balances shall be reduced as appropriate by forfeitures,
withdrawals, payments or distributions, or other amounts properly chargeable to
Participants' Accounts under the Plan during the applicable accounting period.
Notwithstanding the above, solely for purposes of the allocations made under
this Section pursuant to nondiscriminatory rules which may be established by the
Committee, any Rollover Contributions allocated and credited on or after the
first day of the applicable accounting period to the Participant's Rollover
Account, if any, and/or any Contributions allocated and credited on or after the
first day of the applicable accounting period to the Participant's Employee
Account, if any, and/or Employer Account, if any, shall be taken into account to
ensure that such amounts transferred or contributed to the Plan share in the
allocations hereunder with respect to such accounting period; provided, however,
the Committee shall not be required to establish any such rules pursuant hereto.

     4.5. Daily Valuation of Trust Fund:  To the extent that the Plan invests in
          -----------------------------
assets that are subject to daily valuation, the following provisions shall
apply.  For purposes of valuation of the Trust Fund and distribution of the
accrued vested benefit of each Participant, the term "Valuation Date" shall mean
the date upon which a Participant's Account may be valued for purposes of
investment direction and accrued vested benefit distribution.  Each business day
of the Plan Year shall be considered as a Valuation Date.  The Trustee shall,
following the end of each business day, value all assets of the Trust Fund as of
that business day in the following manner:

          (a)  The Trustee shall first compute the fair market value of the
securities and/or the other assets in each investment fund, designated by the
Committee for direction of investment by the Participants of this Plan. This
market value shall be equal to the market price of the fund on the prior
business day applied to the balance of the fund as of the close of business on
the current business day.

          (b)  The Trustee shall, following the computation of the fair market
value, compute each Participant's share of the fund and assign a gain or loss to
each Participant's account.

                                     IV-11
<PAGE>

          (c)  The Trustee shall then account for any requests for additions or
withdrawals made to or from a specific designated investment fund by any
Participant, including allocations of Employer contributions and forfeitures
made as of the date of such allocations and received by the Trustee prior to the
stated deadline on such business day.

     In completing the valuation procedure described above, such adjustments in
the amounts credited to such accounts shall be deemed to have been made on the
business day to which the investment activity relates. No Employer profit
sharing contribution or Employer deferred pay contribution made by an Employer
pursuant to this Plan shall be taken into account until the allocation date
coinciding with or next following the date such contribution was both actually
paid to the Trustee by an Employer and allocated among the accounts of
Participants. It is intended that this Section operate to allocate among each
Participant Account in the Trust Fund, all income of the Trust Fund and changes
in the value of the Trust Fund's assets.

     4.6. Forfeitures and Allocation Thereof:
          ----------------------------------

          (a)  General Rule:  In the event that a Participant terminates
               ------------
     employment with any Employer and all Affiliated Employers, his vested
     interest in his Account will be paid (or deemed to be paid in the case of a
     nonvested Participant, as described below) in accordance with this Section
     and Section 6.6, and any nonvested amount shall be forfeited at such time
     as is provided under subsequent provisions of this Section. Not later than
     the last day of the Plan Year in which such distribution (or deemed
     distribution) occurred, such forfeiture shall be applied first to reinstate
     any Account required to be reinstated during the Plan Year under the
     subsequent provisions of this Section, and any remaining forfeitures shall
     then be applied to reduce any subsequent Contributions of the Employer that
     contributed with respect to the amounts forfeited. Notwithstanding any
     other provisions of the Plan to the contrary, any nonvested amounts that
     were held under the Plan (as in effect immediately prior to the Plan Year
     that commenced on January 1, 1994), in accounts maintained for Participants
     who had incurred at least five (5) consecutive one year periods of
     severance on or before December 31, 1994, shall be deemed to have been
     forfeited during the first Plan Year that commenced immediately after
     December 31, 1994 and shall be applied as herein provided.

          (b)  Actual and Deemed Cash-outs of Nonvested or Partially Vested
               ------------------------------------------------------------
     Accounts Within Two Plan Years After the Participant's Termination of
     ---------------------------------------------------------------------
     Employment; Reinstatement of Such Accounts: For Plan Years beginning on and
     ------------------------------------------
     after January 1, 1987, with respect to any Participant who terminates
     employment with any Employer and all Affiliated Employers and who (i)
     either (A) has a zero percent (0%) vested interest in his Employer
     Contributions Account or (B) has a vested interest in his Employer
     Contributions Account that is greater than zero percent (0%), but is less
     than one hundred percent (100%) and (ii) pursuant to Section 6.6, receives
     a distribution (including a direct rollover pursuant to Section 6.6(c) of
     all or part of the amount distributable) of the full amount of his entire
     vested interest in his Employer Account in the form of a lump sum
     distribution by the close of the second Plan Year following the Plan Year
     in which his

                                     IV-12
<PAGE>

     employment terminated (or is deemed under this Section and Section 6.6 to
     have received such distribution of zero dollars on the date his employment
     terminated in the case of a nonvested terminated Participant described in
     subclause (i)(A) above), which distribution (i) includes the full amount of
     his entire vested interest in his Employer Account as a result of his
     termination of participation in the Plan, and (ii) is $3,500 (or for Plan
     Years beginning on and after January 1, 1998, $5,000) or less, or is more
     than $3,500 (or for Plan Years beginning on and after January 1, 1998,
     $5,000) but is consented to, then, the nonvested, forfeitable amount
     credited to his Employer Contributions Account (as of the Valuation Date
     with respect to which the amount of the distribution is determined) shall
     become a forfeiture as of the distribution date (or as of the date his
     employment terminated if no amount is payable from Employer Contributions
     made to the Plan on his behalf, but such Participant is deemed under this
     Section and Section 6.6 to have received a distribution of zero dollars on
     the date his employment terminated). Provided, however, in the event that a
     partially vested terminated Participant (described in subclause (i)(B) of
     the first sentence of this Section 4.6(b)) who received a distribution
     described in the immediately preceding sentence resumes employment covered
     under the Plan, his Employer Account shall be restored pursuant to Section
     4.6(c) if he repays to the Trustee the full amount of such distribution
     attributable to Employer Contributions prior to the earlier of (i) the date
     on which the Participant incurs a period of five (5) consecutive one year
     periods of severance, or (ii) five (5) years after the first date that he
     is subsequently re-employed by the Employer. If a terminated Participant
     with no amount payable from Employer Contributions made to the Plan on his
     behalf had a zero percent (0%) vested interest in his Employer
     Contributions Account at the time of his termination of employment and thus
     is deemed under this Section and Section 6.6 to have received a
     distribution of a vested interest in his Employer Contributions Account
     equal to zero dollars (thus actually receiving no distribution from his
     Employer Contributions Account as a result of his termination of
     employment), his Employer Contributions Account will be restored if he
     resumes employment covered under the Plan prior to incurring a period of
     five (5) consecutive one year periods of severance. Such reemployed
     Participant shall be deemed to have repaid a distribution of zero dollars
     on the date of his reemployment with the Employer.

          (c)  Amount and Timing of Restoration of Accounts:  With respect to
               --------------------------------------------
     Employer Accounts which are entitled to be restored as a result of
     compliance with all of the requirements of Section 4.6(b), the amount to be
     restored under the provisions of this Section 4.6(c) shall be the amount
     credited to the Participant's Employer Account, both the vested and the
     nonvested portions, immediately prior to the rehired Participant's
     distribution (or deemed distribution), unadjusted by any subsequent gains
     or losses. Such restoration shall be made as soon as administratively
     practicable after the later of the date the Participant resumes employment
     covered under the Plan or the date on which any required repayment is
     completed and shall be effective as of the end of the Plan Year (or other
     period designated by the Committee) coincident with or next following the
     occurrence of the event which gives rise to the restoration of the
     Participant's Employer Account.

                                     IV-13
<PAGE>

          Except as otherwise provided above, a Participant's Employer Account
     shall not be restored upon resumption of employment covered under the Plan.
     Any portion of the Trust Fund attributable to Active Service prior to
     resumption of employment by a Participant whose Employer Account has not
     been restored shall be held and distributed in accordance with applicable
     provisions of the Plan and elections made thereunder. Separate accounts may
     be established and maintained for Contributions allocable to such a
     Participant after his resumption of employment covered under the Plan.

          (d)  Cash-outs of Fully Vested Accounts Within Two Plan Years After
               --------------------------------------------------------------
     the Participant's Termination of Employment; Non-Reinstatement of Such
     ----------------------------------------------------------------------
     Accounts: With respect to any Participant (i) who terminates employment
     --------
     with any Employer and all Affiliated Employers, (ii) who has a vested
     interest in his Employer Contributions Account equal to 100% and (iii) who
     received a distribution from his Employer Account in the form of a lump sum
     distribution by the close of the second Plan Year following the Plan Year
     in which his employment terminated, which distribution (i) includes the
     full amount of his entire vested interest in his Employer Account as a
     result of his termination of participation in the Plan, and (ii) is $3,500
     (or for Plan Years beginning on and after January 1, 1998, $5,000) or less,
     or is more than $3,500 (or for Plan Years beginning on and after January 1,
     1998, $5,000) but is consented to, shall not be permitted to repay to the
     Trustee the full amount of such distribution attributable to Employer
     Contributions in order to restore his Employer Account.

          (e)  Distributions Other than Lump Sum Payments Made After the
               ---------------------------------------------------------
     Participant's Termination of Employment: For Plan Years beginning on and
     ---------------------------------------
     after January 1, 1987, with respect to a Participant (i) who terminates
     employment with any Employer and all Affiliated Employers with greater than
     a zero percent (0%), but less than a one hundred percent (100%), vested
     interest in his Employer Contributions Account and (ii) who received
     payment or commenced to receive payments of a termination distribution from
     his Employer Account in a form other than a lump sum distribution subject
     to the provisions of Section 4.6(b), any amount remaining in his Employer
     Contributions Account shall continue to be maintained as a separate
     account. At any relevant time, such Participant's nonforfeitable portion of
     his separate account shall be determined in accordance with the following
     formula:

                              X = P (AB + D) - D

     For purposes of applying the formula: X is the nonforfeitable portion of
     such separate account at the relevant time; P is the Participant's vested
     interest in his Employer Contributions Account at the relevant time; AB is
     the balance of such separate account at the relevant time; and D is the
     amount of the distribution. For all other purposes of the Plan, a
     Participant's separate account shall be treated as an Employer
     Contributions Account. The forfeitable portion of a terminated
     Participant's separate Employer Contributions Account that is subject to
     such formula shall be forfeited on the date on which such Participant
     incurs a period of five (5) consecutive one year periods of severance.

          (f)  Deferred Distributions of Partially Vested Accounts: With respect
               ---------------------------------------------------
     to a Participant (i) who terminates employment with any Employer and all
     Affiliated Employers with greater than a zero percent (0%), but less than a
     one hundred percent (100%), vested interest in his Employer Contributions
     Account and (ii) who is not otherwise subject to the forfeiture provisions
     of Sections 4.6(b) or (e) above, the forfeitable portion of such terminated
     Participant's Employer Contributions Account shall be forfeited on the date
     on which such Participant incurs a period of five (5) consecutive one year
     periods of severance.

     4.7  Effective Date of Allocations and Adjustments:  The Committee will
          ---------------------------------------------
credit to each eligible Participant's Account the Participant's portion of an
Employer Contributions referred to in Section 4.2 so that all Employer
Contributions will become effective and will be credited to each Participant's
Account as of the end of the Plan Year (or such shorter accounting period as may
be prescribed in Sections 4.2, 4.5, or by the Committee) for which they are
attributable.

     In addition, any amounts contributed to any Participant's Employee Account,
shall be credited as of the last day of the month in which the Employee
Voluntary Contribution was made.  Furthermore, any amount contributed to any
Participant's Rollover Account shall be credited to the appropriate Account as
of the end of the Plan Year (or such shorter accounting period as may be
prescribed by the Committee) to which they are attributable.

     The Committee shall credit to each Participant's Account such Participant's
portion of the (i) income or loss incurred by the Trust Fund as referred to in
Section 4.4, and (ii) appreciation or depreciation of the Trust Fund and any
understatement or overstatement referred to in Section 4.4, as of the end of the
Plan Year (or such shorter accounting period as may be prescribed by the
Committee) for which they are attributable.

     In the event that interim adjustments and allocations are required by
Section 4.5, they will become effective and will be entered in each
Participant's Account as of the end of the applicable accounting period next
preceding the event requiring the interim adjustment and, additionally,
allocation and distribution of benefits during the applicable accounting period
in which the interim adjustment or allocation is made shall take into account
the interim adjustments and allocations.

     4.8  Accounting for Transferred Participant:  In the case of a Participant
          --------------------------------------
who is Transferred during a Plan Year, the Committee, as of the date the
Participant is Transferred, shall transfer on their books such Participant's
Account (including that portion of the Trust Fund allocated thereto) so that
such Participant's Account will always be reflected on the Committee's books as
being attributable to an Employer with whom such Participant is currently
employed.

     4.9  No Vesting Unless Otherwise Prescribed:  No allocations, adjustments,
          --------------------------------------
credits or transfers shall ever vest in any Participant any right, title or
interest in the Trust Fund except at

                                     IV-15
<PAGE>

the times and upon the terms and conditions herein set forth. The Trust Fund
shall be, as to all Participant's Accounts, a commingled fund.

     4.10  Investment Elections with Respect to Commingled Funds:
           -----------------------------------------------------

           (a) Investment Funds Established: The assets of the Plan shall be
               ----------------------------
     invested in one or more categories of assets (which conform to any
     portfolio standards and guidelines established by the Trustee), including
     common stock issued by the Plan Sponsor, as may be determined from time to
     time in the discretion of the Committee and announced and made available on
     an equal basis to all Participants subject to the provisions of this
     Section 4.10. When the Trustee or any agent thereof (i) receives funds to
     be invested or determines that assets from those funds, if applicable,
     should be sold and the proceeds held for a period of time pending
     reinvestment or other purpose, or (ii) has notice that required or
     appropriate filings with the Securities and Exchange Commission have not
     been timely accepted as filed and funds received have been designated to be
     invested in shares of common stock issued by the Plan Sponsor, then, prior
     to completion of required or appropriate filings with the Securities and
     Exchange Commission, such funds may be held in cash or invested in short-
     term investments such as U.S. Treasury bills, commercial paper, demand
     notes, money market funds, any savings accounts, money market accounts,
     certificates of deposit or like investments with the commercial department
     of any bank, including any bank serving as Trustee, as long as they bear a
     reasonable rate of interest and the bank is supervised by the United States
     or a state, any common, pooled or collective or group trust funds, mutual
     funds or insurance contracts, any of which any bank, including any bank
     serving as Trustee or any of its affiliates, or any other corporation may
     now have or in the future may adopt for such short-term investments (the
     governing document of such common, pooled or collective trust fund(s) being
     hereby incorporated herein by reference), and other similar assets which
     may be offered by the federal government, or any national or state bank
     (whether or not serving as Trustee hereunder), and as may be determined by
     the Trustee, in its discretion, which assets will remain a part of the fund
     to which they would otherwise relate.

           (b) Election Procedures Established: If Participants are given the
               -------------------------------
     right to designate the funds in which their Accounts are invested pursuant
     to Section 4.10(a), on such form as shall be prescribed by the Committee,
     each Participant shall designate the percentage of his Account (as such
     Account presently exists and the percentage of future contributions, if
     any, to be allocated to such Account) to be invested in any one or more
     funds, as such funds may be established from time to time as set forth in
     Section 4.10(a). At such times as shall be prescribed by the Committee in
     its discretion, the percentage elected to be placed in any one fund may be
     changed by the Participant, which change will be effective after such
     period of time as shall be established by the Committee. The Committee
     shall determine whether any such change as to investments will change the
     Participant's Account as it presently exists or whether it will be only
     effective as to succeeding investments of Contributions; however, any such
     change, when made, shall continue to be effective for all succeeding
     investments of Contributions until revoked or

                                     IV-16
<PAGE>

     changed in a like manner. The rules established and the discretion
     exercised by the Committee hereunder shall apply to all Participants on a
     nondiscriminatory basis. The rules and procedures that are prescribed by
     the Committee as described herein may include Telephone Procedures, and in
     such case the Trustee shall be authorized to accept elections made by
     Participants pursuant to such Telephone Procedures.

           (c) Investment in Employer Securities: Notwithstanding anything to
               ---------------------------------
     the contrary herein, except as otherwise may be determined by the Committee
     in its sole discretion, no investment shall be made by the Trustee in any
     securities other than those permitted under applicable provisions of The
     Securities Act of the State of Texas, as amended from time to time, and so
     long as the transactions contemplated by this Plan remain otherwise exempt
     from The Securities Act of the State of Texas and the Trustee is not
     required to register the Plan as a security under applicable provisions of
     such act. In addition, except, with respect to periods beginning on and
     after August 1, 1996, as otherwise may be determined by the Committee in
     its sole discretion, unless the Plan would not have to be registered under
     the federal Securities Act of 1933, no amount in excess of an Employer's
     Contribution (other than Elective Contributions) shall be allocated to the
     purchase of securities issued by an Employer or any company directly or
     indirectly controlling, controlled by or under common control with an
     Employer. With respect to periods beginning on and after August 1, 1996,
     any such determination by the Committee shall be evidenced by formal
     minutes reflecting such action of the Committee or by a unanimous written
     consent of the members of the Committee and shall be appropriately
     communicated to the affected Participants, and must be preapproved by the
     Board or ratified by the Board at the next regularly scheduled meeting of
     the Board.

           In the event that common stock of the Plan Sponsor ("Company Stock")
     is authorized by the Committee for investment through a fund ("Company
     Stock Fund") under which shares of Company Stock are allocated to the
     Accounts of Participants and Beneficiaries, who pursuant to the Plan,
     direct the Trustee to invest in the Company Stock Fund, Sections 9.4 and
     9.5 shall govern the rights of the affected Participants and Beneficiaries
     with respect to voting and tending shares of Company Stock allocated to
     their Accounts.

           With respect to periods beginning on and after August 1, 1996,
     notwithstanding anything to the contrary herein, in order to assure
     compliance with rules promulgated under the Securities Exchange Act of 1934
     (the "Exchange Act"), the Committee may, in its sole discretion, impose
     additional restrictions on investment in the Company Stock Fund by any
     Participant who at any time during any give Plan Year is subject to the
     provisions of Section 16 of the Exchange Act. Such restrictions may
     include, without limitation, an unqualified prohibition on investment in
     the Company Stock Fund by any Participant described in the immediately
     preceding sentence. Any such decision by the Committee shall be evidenced
     by formal minutes reflecting such action of the Committee or by a unanimous
     written consent of the members of the Committee and shall be appropriately
     communicated to the affected Participants, and must be pre-approved by the
     Board or ratified by the Board at the next regularly scheduled meeting of
     the Board.

           (d)  Allocations Attributable to Directed Investments in Commingled
                --------------------------------------------------------------
     Funds: If Participants are given the right to designate the funds in which
     -----
     their Accounts are invested pursuant to Section 4.10(a), each valuation and
     determination of income or loss and appreciation or depreciation provided
     for hereunder shall reflect the value of the different categories of assets
     separately. The Committee shall allocate appreciation, depreciation,
     income, and loss attributable to each such category of assets among the
     Participants' various Accounts (each type of Account being considered
     separately) in the ratio that the amount in each Account which was invested
     in a particular category as of the first day of the applicable accounting
     period bears to the amount in all Accounts which was invested in such
     category as of the first day of such applicable accounting period.

           (e)  Valuation Dates: Pursuant to nondiscriminatory rules established
                ---------------
     by the Committee and uniformly applied to similarly situated Participants,
     separate valuation dates may be established (with respect to one
     Participant's Account which may not apply to another Account) as necessary
     or appropriate to facilitate measurement of investment performance, changes
     in investments or distribution of Accounts of Participants who direct (or
     are deemed to direct) investment thereof pursuant to the provisions of this
     Section 4.10.

           (f)  Section 404(c) of the Act: Except as may otherwise be prescribed
                -------------------------
     by the Committee, categories of assets, election procedures and other rules
     relating to investment elections under this Section shall comply with the
     requirements of Section 404(c) of the Act.

     4.11. Special Transition Rule:  Notwithstanding any other provisions of the
           -----------------------
Plan to the contrary, if the Plan is retroactively effective with respect to any
Plan Year (or other applicable accounting period) of a Prior Plan, the Account
of any individual who was a participant or Participant during such Plan Year (or
other applicable accounting period) shall be credited with any Employer
Contributions under the Plan attributable to such Plan Year if such
Participant's Account would have been entitled to such an allocation under the
Prior Plan immediately prior to the later of (i) the adoption of or (ii) the
effective date of the amendment and continuation of the Prior Plan under the
form of the Plan.  In addition, notwithstanding any other provision of the Plan
to the contrary, if the participant or Participant described in the preceding
sentence would have been so entitled under the Prior Plan immediately prior to
the later of (i) the adoption of or (ii) the effective date of, its amendment
and continuation under the form of the Plan, the Account of such Participant
shall be charged or credited with its proportionate share of the Trust Fund's
income, gains, losses, appreciation or depreciation attributable to the Plan
Year or other applicable accounting period (or portion thereof).

                                   RETIREMENT

     5.1  Early Retirement:  For Plan Years beginning on and after January 1,
          ----------------
1996, a Participant may retire on the first day of any month coincident with or
next following the date on which he has attained age fifty-five (55) years or
older and has completed at least five (5) years of Active Service for vesting
purposes.

     5.2  Normal Retirement:  A Participant may retire on the first day of the
          -----------------
month coincident with or immediately following his attainment of normal
retirement age.  A Participant's normal retirement age shall be his sixty-fifth
(65th) birthday, from which time he shall henceforth be one hundred percent
(100%) vested in his Account.

     5.3  Late Retirement:  A Participant may continue his employment after he
          ---------------
attains normal retirement age (subject to satisfactory performance of his
assigned duties); provided, that he shall have the right to retire on any
subsequent date.


     5.4  Rights of Participants and Prohibition of Unauthorized Distribution:
          -------------------------------------------------------------------
Until a Participant retires or otherwise terminates service he shall be accorded
all rights as a Participant under the Plan, but, subject to Section 6.6, he
shall receive no distribution until he actually retires or otherwise becomes
entitled to a distribution under the provisions of Article VI.

                                      V-1

                                  ARTICLE VI.

                            DISTRIBUTION OF BENEFITS

     Distributions under the Trust Fund shall be made to Participants, spouses,
Beneficiaries, executors or administrators, as the case may be, only upon the
following conditions and in the manner specified.

     6.1. Death Benefit:  On the death of a Participant or a Retired Participant
          -------------
prior to complete distribution of such Participant's or Retired Participant's
Account, his death benefit shall be (i) 100% of the amount credited to his
Account as of the end of the applicable accounting period coincident with or
next preceding the date of the Participant's death, (ii) an amount equal to any
(a) Rollover Contributions, and (b) Elective Contributions recharacterized as
Employee Voluntary Contributions, (iii) an amount equal to any Employee
Voluntary Contributions or Employer Contributions made by, or on behalf of, such
Participant after the end of such accounting period, and, if applicable, (iv) to
the extent that the Participant's Account has any undistributed balance which
has not been paid as of the end of the applicable accounting period (for which
the last valuation was made), that portion of the periodic adjustments and
allocations required by Article IV to be credited to the Participant's Account
as of the end of the applicable accounting period next preceding or coincident
with payment of the benefits payable.  In accordance with Section 6.10, the
death benefit described in the immediately preceding sentence shall be reduced
by any security interest held by the Plan by reason of any outstanding loan to
the Participant.

     The death benefit shall be paid to the Participant's surviving spouse, or
if there is no surviving spouse or the surviving spouse consents in the manner
described below, to such Participant's designated Beneficiary (other than such
surviving spouse). At any time, subject to the following provisions of this
Section, each Participant shall have the right to designate any Beneficiary or
Beneficiaries to receive his death benefit and shall have the unrestricted right
to revoke any such designation; provided, however, subject to the subsequent
provisions hereof which permit the spouse to consent to the Participant's waiver
of the requirements of this sentence, any new designation of a Beneficiary
(other than the Participant's spouse) by a Participant who is lawfully married
(or deemed to be married under applicable local law) shall require a new spousal
consent. Provided further that (i) any waiver by any married Participant (with
spousal consent as required hereunder) of the spousal death benefit otherwise
payable hereunder is not required to specify any optional form of benefit
payment, (ii) any such married Participant may change any optional form of
spousal death benefit payment available under the Plan without obtaining spousal
consent, and (iii) a Beneficiary may elect any optional form of payment
available under the Plan to the extent permitted under applicable provisions of
the Plan. Each such designation or revocation by a Participant shall be
evidenced by a written instrument which shall be (i) limited to a benefit for at
least one specific Beneficiary (including nonspouse Beneficiary, or any class of
Beneficiaries or any contingent Beneficiaries), (ii) filed with the Committee,
(iii) signed by the Participant, and (iv) bear the signature of at least two
persons (at least one of which shall be a representative designated by the
Committee or a Notary Public) as witnesses to his signature.

                                     VI-1
<PAGE>

     With respect to any Participant who is lawfully married (or deemed to be
married under applicable local law), any such Participant's designation of a
Beneficiary (other than the Participant's spouse) to receive any portion of such
death benefit shall be deemed to be ineffective, unless the Participant's spouse
consents to such designation and acknowledges the effect of such election, which
consent and acknowledgement shall be evidenced by a written instrument which
shall be (i) limited to a benefit for at least one specific Beneficiary which
may not be changed without spousal consent (or the spouse's consent expressly
permits at least one additional designation of another Beneficiary without any
requirement of further consent by such spouse if such spouse's consent expressly
acknowledges that a more limited consent could be provided), (ii) filed with the
Committee, (iii) signed by the spouse and (iv) bear the signature of at least
two persons (at least one of which must be a representative designated by the
Committee or a Notary Public) as witnesses to the signature.  Notwithstanding
the immediately preceding sentence, a Participant's designation of a Beneficiary
(other than the Participant's spouse) shall be effective if it is established to
the satisfaction of the Committee that the consent required in the preceding
sentence may not be obtained because (i) there is no spouse, (ii) the spouse
cannot be located, (iii) the Participant has provided a duly certified copy of a
court order issued by a court of competent jurisdiction which recognizes that
the Participant is legally separated or has been abandoned (under applicable
local law) and the Committee has not received a duly certified copy of a
qualified domestic relations order (described in Section 414(p) of the Code)
which requires spousal consent, or (iv) there exists such other circumstance (as
are prescribed in regulations or other authority issued under Sections
401(a)(11) and 417(a)(2) of the Code) which obviate the necessity of obtaining
the consent described in the preceding sentence.  In addition, if the surviving
spouse is not legally competent to give consent, such spouse's legal guardian,
which may be the Participant, may give the consent required hereunder.  Any
consent by a Participant's spouse (or establishment that the consent of a
Participant's spouse may not be obtained) shall be effective only with respect
to such spouse.

     Notwithstanding any other provision hereof to the contrary, commencing with
Plan Years beginning after October 22, 1986, any spousal consent which expressly
acknowledges that a more limited consent could be provided may expressly provide
that the spouse consents to the designation by the Participant of any
Beneficiary (or any number of specified Beneficiaries) without any requirement
of further consent by the spouse and, in such event, no further spousal consent
shall be required, provided that any change of Beneficiary by the Participant
does not exceed any limit contained in the spouse's consent on such
Participant's right to change his Beneficiary.  Any spousal consent shall be
deemed to be revocable unless it is expressly made irrevocable at the election
of the Participant's spouse.

     Any designation of a Beneficiary (other than the Participant's spouse)
which otherwise meets the above requirements of this Section shall become
inoperative in the event that (i) the Participant subsequently marries (or
subsequently is deemed to be married under applicable local law), (ii) any
missing spouse is located or (iii) any other circumstance which earlier
precluded the necessity of obtaining consent of the Participant's spouse no
longer exists. If no designation of Beneficiary is on file with the Committee at
the time of the Participant's death, or if the Committee for any reason
determines that such designation is ineffective, then, such Participant's

                                     VI-2
<PAGE>

spouse, if then living, or if not, then the executor, administrator, or other
personal representative of the estate of such Participant shall be conclusively
deemed to be the Beneficiary designated to receive such Participant's death
benefit.

     The provisions of this Section are intended to comply with the requirements
of Sections 401(a)(11) and 417(a)(2) of the Code. To the extent any provision
hereof is inconsistent with the preceding sentence, such provision shall be
deemed to be inoperative and the Plan shall be operated in a manner which
complies with the requirements of the immediately preceding sentence.

     Whenever the Trustee is authorized by this Plan or by a designation of
Beneficiary to pay funds to a minor or an incompetent, the Trustee shall be
authorized to pay such funds to a parent of such minor, to a guardian of such
minor or incompetent, or directly to such minor, or to apply such funds for the
benefit of such minor or incompetent in such manner as the Committee may in
writing direct.  The Trustee, Committee, and Employer shall be fully discharged
with respect to any payment made in accordance with the preceding sentence.

     6.2. Retirement Benefit:  Upon the retirement of a Participant, his
          ------------------
retirement benefit shall be 100% of the amount credited to his Account as of the
end of the applicable accounting period coincident with or next preceding his
retirement, plus an aggregate amount equal to the sum of the amounts described
in clauses (ii), (iii) and (iv) of the first paragraph of Section 6.1.
Provided, however, in accordance with the provisions of Section 6.10, the
retirement benefit described in the preceding sentence shall be reduced by any
security interest held by the Plan by reason of any outstanding loan to the
Participant.

     6.3. Total and Permanent Disability Benefit:  In the event that the
          --------------------------------------
Committee determines that a Participant is suffering from a Total and Permanent
Disability, his disability benefit shall be 100% of the amount credited to his
Account as of the end of the applicable accounting period coincident with or
next preceding such determination, plus an aggregate amount equal to the sum of
the amounts described in clauses (ii), (iii) and (iv) of the first paragraph of
Section 6.1.  In accordance with Section 6.10, the disability benefit described
in the preceding sentence shall be reduced by any security interest held by the
Plan by reason of any outstanding loan to the Participant.

     6.4. Severance Benefit:  Upon a Participant's severance from employment
          -----------------
with an Employer and all Affiliated Employers, for any reason other than death,
retirement, or Total and Permanent Disability, his severance benefit shall be an
amount equal to the sum of:  (i) 100% of the total amount credited to his
Employee Account, if any, Employer Nonforfeitable Contributions Account, and
Rollover Account, if any, as of the end of the applicable accounting period (for
which the last valuation was made) coincident with or next preceding the date of
such Participant's severance, together with an amount equal to any Employee
Voluntary Contributions made or recharacterized after the end of such accounting
period, any Contributions, Rollover Contributions or direct transfers made by or
on behalf of the Participant after the end of such accounting period which were
allocated to any of the above-listed Accounts, and (ii) the percentage of the
total amount credited to his Employer Contributions Account, as of the end of

such accounting period coincident with or next preceding the date of such
Participant's severance, together with the percentage of the amount of any
Contributions made on behalf of such Participant after the end of such
accounting period which were allocated to an Employer Contributions Account, as
such percentage is shown in the table set out below for the total number of
years of Active Service credited to the Participant prior to his date of
severance of employment, and, if applicable, (iii) to the extent that the
Participant's Account has any undistributed balance which has not been paid as
of the end of the applicable accounting period (for which the last valuation was
made), that portion of the periodic adjustments and allocations required by
Article IV to be credited to the Participant's Account as of the end of the
applicable accounting period next preceding or coincident with payment of
benefits described above.  In accordance with Section 6.10, the severance
benefit described in the immediately preceding sentence shall be reduced by any
security interest held by the Plan by reason of any outstanding loan to the
Participant.

Less than one year............................................. 0%
One year, but less than two years............................. 20%
Two years, but less than three years.......................... 40%
Three years, but less than four years......................... 60%
Four years, but less than five years.......................... 80%
Five years, or more.......................................... 100%

A Participant who is a former Employee of an Employer shall be entitled to
benefits under the vesting schedule and other terms and provisions of the Plan
or Prior Plan as in effect on the date that the Participant's employment with an
Employer was terminated.  The above vesting schedule is subject to automatic
100% vesting in the event of a full or partial termination of the Plan pursuant
to Section 11.5.  The amount credited to such Participant's Account which is not
vested upon distribution shall be forfeited and reallocated as provided in
Section 4.6.

     6.5. Accounting for Distributions; Offsets in Special Circumstances:
          --------------------------------------------------------------
Subject to the provisions of Section 4.6 governing restoration of Participants'
Accounts and to Section 4.10 concerning individual investment direction, if
applicable, any distribution of any benefits under the Plan (and any forfeitures
arising incident thereto) shall be subtracted from the affected Participant's
Account balance as of the end of the Plan Year (or such shorter accounting
period as may be prescribed by the Committee) coincident with or next preceding
the applicable accounting period in which such distribution was paid.  Moreover,
notwithstanding any other provision of the Plan to the contrary, if after a
Participant's employment with an Employer and all other Affiliated Employers
terminates, such person is reemployed by an Employer after receiving a
distribution pursuant to Section 6.6 and again becomes eligible for membership,
and has his Employer Account restored pursuant to Section 4.6, then any benefits
that such Participant may become entitled to receive hereunder after reentry in
the Plan shall be reduced by any amounts distributed from his Employer Account
which were not repaid by such Participant incident to restoration of his
Employer Account pursuant to Section 4.6.

     6.6. Distributions-Settlement Options:
          --------------------------------

          (a)  General Rules:
               -------------

               (i)  Form and Method of Payment of Benefits: Subject to Sections
                    --------------------------------------
          3.2, 3.4, 6.8, 6.11, 11.4, 11.7 and 12.3, distributions shall be made
          under the Plan only upon the occurrence of one of the events described
          in Sections 6.1 through 6.4. To the extent required by Section 401(k)
          of the Code, the limitations of the preceding sentence shall continue
          to apply even if Trust Fund assets attributable to any Participant's
          Account are transferred to another plan pursuant to applicable
          provisions of Section 8.2, 9.2 or 11.7. Subject to the following
          provisions of this Section 6.6(a) and Section 6.6(b), distributions
          provided for in the Plan shall be made in cash under one of the
          settlement options available under the Plan as elected by the
          Participant; provided, however, in the absence of such election,
          settlement shall be made in the form of a lump sum payment or, to the
          extent elected by the distributee, in the form of a direct rollover as
          described in Section 6.6(c) if the requirements of that section are
          satisfied.

               With respect to any amounts invested in common stock of the Plan
          Sponsor, distribution shall be paid in cash in an amount equal to the
          value (as of the date or dates shares of common stock of the Plan
          Sponsor allocated and credited to the Participant's Account are
          converted into cash) of the Participant's vested interest in shares of
          common stock of the Plan Sponsor allocated and credited to such
          Participants Account, or in whole shares of common stock of the Plan
          Sponsor, or in any combination thereof as elected by the Participant;
          provided, however, that any fractional shares of the Plan Sponsor to
          which the Participant or Beneficiary may be entitled shall be valued
          (as of the date immediately prior to the date of distribution) and
          paid in cash.

               A Participant must consent, in writing, to any distribution
          required hereunder if the present value of the Participant's vested
          Account balance (derived from Employer and any Employee Contributions)
          distributable under the Plan exceeds $3,500 (or for Plan Years
          beginning on and after January 1, 1998, $5,000) and the Participant
          has not attained the normal retirement age described in Article V.
          After the Participant's death, benefits may be paid in accordance with
          applicable provisions of the Plan without regard to the requirements
          of the immediately preceding sentence. The present value of the
          settlement under any option shall be no less than the amount that
          would be payable as an immediate lump-sum distribution. The settlement
          options available under the Plan are as follows:

                    (1)  A lump-sum payment; or
                         ------------------

                    (2)  Periodic installments payments. The amount payable to
                         ------------------------------
               the Participant under this option shall be paid in equal monthly
               or quarterly

                                     VI-5
<PAGE>

               installments for a certain period of time that does not
               exceed the life expectancy of the Participant or joint life and
               last survivor expectancy of the Participant and a designated
               Beneficiary (determined as of the date that payment of benefits
               commences).  At the election of the Participant, the
               Participant's Account from which such installments are payable
               may be (a) maintained as a part of the Trust Fund and be subject
               to its proportionate share of the income, appreciation or
               depreciation of the Trust Fund as a whole, but not subject to any
               further Contributions, or (b) segregated and placed on deposit at
               interest in an insured depository.

          A Participant who elects periodic installments under this option and
          begins to receive such periodic payments may, at a future date but not
          more often than once in each calendar year, file a new election with
          the Committee under which such Participant may (i) modify the certain
          period of time over which such installment payments are payable (but
          in no event over a period that exceeds: (A) the life expectancy of the
          Participant or the joint life expectancy of the Participant and a
          designated Beneficiary, as determined as of the date that such
          periodic installments originally began under this option) or (B) in
          the case of a Participant who has reached his Required Beginning Date
          (as defined in Section 6.6(a)(1)(iv)(1) below), a period that is
          longer than the period over which payments were being made at the time
          such Participant reached his Required Beginning Date); or (ii) elect
          to receive a lump sum payment of his entire remaining Account balance
          under the Plan, payable as soon as administratively feasible after the
          Committee receives such election.

          None of the above described settlement options may be made in the form
          of an annuity payable for the life of any Participant, Beneficiary or
          any other person.

              (ii)  Distributable Account Balance Does Not Exceed $3,500 (Or
                    ---------------------------------------------------------
          For Plan Years Beginning On And After January 1, 1998, $5,000). If the
          --------------------------------------------------------------
          present value of a Participant's vested Account balance (derived from
          Employer Contributions and any Employee Contributions) which is
          distributable under the Plan does not exceed $3,500 (or for Plan Years
          beginning on and after January 1, 1998, $5,000), then except to the
          extent that the distributee has properly elected a direct rollover
          pursuant to Section 6.6(c) hereof, the Participant's vested interest
          in his Account balance shall be distributed in a single sum in cash.
          Any Participant who receives a distribution pursuant to the preceding
          sentence and who does not have a vested interest in his Account
          balance (derived from Employer Contributions) distributable under the
          Plan, shall be deemed to have received a distribution of a vested
          Account balance (derived from Employer Contributions) equal to zero.
          Such distribution may be made without the necessity of obtaining the
          consent of the Participant and/or his spouse or any Beneficiary other
          than such Participant's spouse, if applicable. Such payment may be
          made as soon as practicable, but (absent circumstances beyond the
          control of the Committee) in no

                                     VI-6
<PAGE>

          event later than one year after the last day of the Plan Year in which
          the Participant's employment with an Employer and all Affiliated
          Employers is terminated.

              (iii) Distributable Account Balance Exceeds $3,500 (Or For Plan
                    ---------------------------------------------------------
          Years Beginning On And After January 1, 1998, $5,000): If the present
          -----------------------------------------------------
          value of a Participant's vested Account balance (derived from Employer
          Contributions and any Employee Contributions) which is distributable
          under the Plan is in excess of $3,500 (or for Plan Years beginning on
          and after January 1, 1998, $5,000) and if the Participant provides the
          Committee written consent to the distribution, the Committee shall
          direct the Trustee to make settlement of the Participant's Account
          within the 60-day period (or as soon as practicable) after the
          Committee receives such consent, but (absent circumstances beyond the
          control of the Committee) in no event later than sixty (60) days after
          the last day of the Plan Year in which the Participant's employment
          with an Employer and all Affiliated Employers is terminated. Except as
          provided in the immediately succeeding paragraph of this Section
          6.6(a)(iii), no such written consent shall be considered valid unless
          (within the period which shall begin no more than ninety (90) days
          before the annuity starting date (described below) and shall end no
          less than thirty (30) days before the annuity starting date) such
          Participant has received a general written explanation of the general
          features and values of each optional form of payment available under
          the Plan, and has been informed in writing of his right to defer
          receipt of the distribution. Such written explanation may be provided
          by mail, personal delivery, or other means which would normally ensure
          or facilitate the continued attention of the Participant during the
          period prescribed below in which the Participant is to consent to the
          distribution or otherwise be deemed to have elected to defer receipt
          (as set out below). Written consent of the Participant shall be
          invalid unless it is given after receipt of the written explanation
          described above and not more than ninety (90) days before the annuity
          starting date. The term "annuity starting date" means the first day of
          the first period for which an amount is paid pursuant to any
          settlement option available under the Plan.

              Notwithstanding the provisions of the immediately preceding
          paragraph of this Section 6.6(a)(iii), if a distribution is one to
          which sections 401(a)(11) and 417 of the Code do not apply, such
          distribution may commence less than 30 days after the notice required
          under section 1.411(a)-11(c) of the Regulations is given, provided
          that:

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

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

                                     VI-7
<PAGE>

              In addition, subject to a designated Beneficiary's right to elect
          the date of settlement in the case of a Participant who dies prior to
          receipt of any benefits under the Plan, a valid written consent to
          such distribution may be made by a Participant without the necessity
          of obtaining the consent of the Participant's spouse or any
          Beneficiary other than such Participant's spouse, if applicable. If
          the present value of such Participant's vested Account balance which
          is distributable under the Plan is in excess of $3,500 (or for Plan
          Years beginning on and after January 1, 1998, $5,000) at the time of
          any distribution, the present value of such Account balance at any
          subsequent time shall be deemed to exceed $3,500 (or for Plan Years
          beginning on and after January 1, 1998, $5,000).

              If the Committee fails to receive the Participant's written
          consent to the distribution within 60 days after his receipt of the
          written explanation described above, subject to the distribution
          requirements of Section 6.6(a)(iv) below, such Participant shall be
          deemed to have irrevocably elected to defer receipt of settlement of
          his Account to a date that is not earlier than the earlier of the date
          of his death or of his attainment of normal retirement age hereunder;
          except that (i) such a Participant who, on the above described
          termination date, met any service requirement for early retirement may
          file a claim with the Committee requesting settlement to be made or
          commence on any date which is after his early retirement date or (ii)
          any other Participant may file a claim with the Committee requesting
          settlement to be made or commence on any date which is after his
          normal retirement date, provided that in either case such a claim for
          settlement is filed with the Committee within a reasonable time before
          such date. The balance credited to the Account of any Participant
          during any period of deferral of his settlement shall continue to be
          part of the commingled Trust Fund and thus shall continue to share in
          any appreciation or depreciation of the Trust Fund and in any income
          or losses incurred by the Trust Fund pending distribution of such
          Account balance; provided, however, no further Contributions shall be
          credited to his Account.

              If Participants are permitted to direct the investment of their
          Accounts in accordance with Section 4.10, unless the Committee
          otherwise prescribes pursuant to uniformly applied nondiscriminatory
          rules established by the Committee, a Participant who is a former
          Employee of an Employer shall be entitled to direct the investment of
          such Participant's Account after the Participant becomes entitled to a
          distribution under Article VI of the Plan.

              (iv) Distribution Requirements: Capitalized terms used in this
                   -------------------------
          Section 6.6(a)(iv) which are not otherwise defined in Article I are
          defined in Section 6.6(a)(iv)(5). The requirements of this Section
          6.6(a)(iv) shall apply to any distribution of a Participant's or
          Beneficiary's vested Benefit and will take precedence over any
          inconsistent provisions of the Plan. All distributions required under
          Article VI shall be determined and made in accordance with

                                     VI-8
<PAGE>

          Section 401(a)(9) of the Code, including the minimum distribution
          incidental benefit requirement of Section 1.401(a)(9)-2 of the
          proposed Income Tax Regulations or any successor or final regulation
          issued with respect thereto. Unless otherwise specified, the
          provisions of this Section 6.6(a)(iv) apply to calendar years
          beginning after December 31, 1984.

                    (1)  Required Beginning Date. Notwithstanding any other
                         -----------------------
              provision of the Plan to the contrary, but subject to the
              immediately succeeding sentence, unless the Participant otherwise
              elects, the Trustee must make full settlement or begin Benefit
              payments to the Participant not later than the 60th day after the
              latest of the close of the Plan Year in which: (a) the Participant
              attains the normal retirement age set out in Article V, (b) occurs
              the tenth (10th) anniversary of the year in which the Participant
              commenced participation in the Plan, or (c) the Participant
              terminates employment with an Employer. The entire vested Benefit
              payable to a Participant must be distributed or commence to be
              distributed no later than the Required Beginning Date.

                    (2)  Limits on Distribution Periods. As of the first
                         ------------------------------
              Distribution Calendar Year, distributions, if not made in a
              single-sum, may only be made over a period which shall not extend
              beyond one of the following periods (or a combination thereof):

                         (A)  the Life Expectancy of the Participant, or

                         (B)  the Life Expectancy of the Participant and a
                    Designated Beneficiary.

                    (3)  Determination of Amount to be Distributed Each Year. If
                         ---------------------------------------------------
          the Participant's vested Benefit is to be distributed in other than a
          single sum, the following minimum distribution rules shall apply on or
          after the Required Beginning Date.

                         (A)  If a Participant's vested Benefit is to be
                    distributed over (i) 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 (ii) a period not extending beyond
                    the Life Expectancy of the Designated Beneficiary, the
                    amount required to be distributed for each calendar year,
                    beginning with distributions for the first Distribution
                    Calendar Year, must at least equal the quotient obtained by
                    dividing the Participant's vested Benefit by the Applicable
                    Life Expectancy.

                                     VI-9
<PAGE>

                         (B)  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.

                         (C)  For calendar years beginning after December 31,
                    1988, the amount to be distributed each year, beginning with
                    the distribution for the first Distribution Calendar Year
                    shall not be less than the quotient obtained by dividing the
                    Participant's vested Benefit by the lesser of (i) the
                    Applicable Life Expectancy or (ii) if the Participant's
                    spouse is not the Designated Beneficiary, the applicable
                    divisor determined from the table set forth in Q & A-4 of
                    Section 1.401(a)(9)-2 of the proposed Income Tax Regulations
                    or any successor or final regulation issued with respect
                    thereto. Distributions after the death of the Participant
                    shall be distributed using the Applicable Life Expectancy in

                         in a subsequent year.

          (b)  Special Transition Rules:  Notwithstanding the above requirements
               ------------------------
     of Sections 6.6(a), if applicable, distribution on behalf of any
     Participant, including a Key Employee in a Top-Heavy plan (as such terms
     are defined in Section 7.4), may be made in accordance with the following
     requirements of this Section 6.6(b) (regardless of when such distribution
     commences):

               (i)    The distribution by the Plan is one which would not have
          disqualified such Plan under Section 401(a)(9) of the Code as in
          effect prior to amendment by the Tax Reform Act of 1984;

               (ii)   The distribution is in accordance with a method of
          distribution designated by the Participant whose interest in the Plan
          is being distributed or, if the Participant is deceased, by a
          Beneficiary of such Participant;

               (iii)  Such designation was in writing, was signed by the
          Participant or the Beneficiary, and was made before January 1, 1984;

               (iv)   The Participant had accrued a benefit under the Plan or
          any Prior Plan as of December 31, 1983; and

               (v)    The method of distribution designated by the Participant
          or the Beneficiary specifies the time at which distribution will
          commence, the period over which distributions will be made, and in the
          case of any distribution upon the Participant's death, the
          Beneficiaries of the Participant listed in order of priority.

     A distribution upon death will not be covered by this Section 6.6(b) unless
     the information in the designation contains the required information
     described above with respect to distribution to be made upon the death of
     the Participant. For any distribution which commences before January 1,
     1984, but continues after December 31, 1983, the Participant, or the
     Beneficiary, to whom such distribution is being made, will be presumed to
     have designated that method of distribution if the method of distribution
     was specified in writing and the distribution satisfies the requirements of
     applicable law. If a designation is revoked, any subsequent distribution
     must satisfy the requirements of Section 401(a)(9) of the Code and
     regulations or other authority issued thereunder. If a designation is
     revoked subsequent to the date distributions are required to begin, the
     Plan must distribute by the end of the calendar year following the calendar
     year in which the

                                     VI-15
<PAGE>

     revocation occurs the total amount not yet distributed which would have
     been required to have been distributed to satisfy Section 401(a)(9) of the
     Code and regulations or other authority issued thereunder, but for the
     Section 242(b)(2) election. For calendar years beginning after December 31,
     1988, such distributions must meet the minimum distribution incidental
     benefit requirements set forth in Section 1.401(a)(9)-2 of the proposed
     Income Tax Regulations or any successor regulation. Any changes in the
     designation will be considered to be a revocation of the designation.
     However, the mere substitution or addition of another Beneficiary (one not
     named in the designation) under the designation will not be considered to
     be a revocation of the designation, so long as such substitution or
     addition does not alter the period over which distributions are to be made
     under the designation, directly or indirectly (for example, by altering the
     relevant measuring life). In the event that an amount is transferred or
     rolled over from one plan to another plan, the rules set forth in the
     regulations or other authority issued under Section 401(a)(9) of the Code
     shall apply.

          (c)  Special Rules Regarding Direct Rollovers:
               -----------------------------------------

               (i)  General Rule: This Section 6.6(c) 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 6.6(c), a distributee may elect, at the
          time and in the manner prescribed by the Committee, to have all or any
          portion (provided that such portion is at least $500) of an eligible
          rollover distribution paid, in a direct rollover, directly to an
          eligible retirement plan specified by the distributee. Only one direct
          rollover shall be allowed for each eligible rollover distribution.
          Prior to any direct rollover pursuant to this Section 6.6(c), the
          distributee shall furnish to the Committee a statement from the plan
          administrator or trustee of the qualified plan, or the trustee or
          custodian of the individual retirement account or annuity, to which
          the direct rollover is to be transferred that such plan, account or
          annuity is, or is intended to be an eligible retirement plan.

               (ii) Definitions.
                    ------------

                    (1)  Eligible rollover distribution: An eligible rollover
                         -------------------------------
               distribution is any distribution of all or any portion (that is
               at least $500) 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
               (i) 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 (ii) for a specified
               period of ten years or more; (B) any distribution to the extent
               such distribution is required under Section 401(a)(9) of the
               Code; (C) the portion of any distribution that is not includable
               in gross income (determined without regard to the exclusion for
               net unrealized appreciation with respect to employer

                                     VI-16
<PAGE>

               securities) (D) any distribution that, when aggregated with all
               other eligible rollover distributions within the same taxable
               year of the distributee from this Plan, are reasonably expected
               to total less than $200; and (E) any other amounts that are
               treated as not being eligible rollover distributions under
               Temporary Regulation Section 1.401(a)(31)-1T or other guidance
               issued by applicable governmental authority under Section
               401(a)(31) of the Code.

                      (2)  Eligible retirement plan:  An eligible retirement
                           ------------------------
                  plan is an individual retirement account described in Section
                  408(a) of the Code, an individual retirement annuity described
                  in Section 408(b) of the Code, an annuity plan described in
                  Section 403(a) of the Code, or a qualified trust described in
                  Section 401(a) of the Code, that accepts the distributee's
                  eligible rollover distribution. However, in the case of an
                  eligible rollover distribution to the surviving spouse, an
                  eligible retirement plan is an individual retirement account
                  or individual retirement annuity.

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

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

          (iii)   Effect of Failure to Make Direct Rollover Election:  In
                  --------------------------------------------------
     the event that a distributee entitled to an eligible rollover distribution
     under this Plan fails to elect, in the time and manner prescribed by the
     Committee, that a direct rollover be made on his behalf to an eligible
     retirement plan, such distributee shall be deemed to have elected that no
     such direct rollover be made and that distribution of his interest under
     the Plan be made in accordance with otherwise applicable provisions of the
     Plan, but such deemed elections will only be treated as having been made if
     such distributee was provided with the notice and explanation described in
     Section 402(f) of the Code not more than 90 days and not less than 30 days,
     before making such distribution.

     6.7. Lost Participants or Beneficiaries; Escheat:  If a Participant or
          -------------------------------------------
Beneficiary thereof cannot be located within sixty (60) days of the date any
benefits payable under the Plan should be paid or commence to be paid pursuant
to Section 6.6, the Participant's entire Account may be forfeited and allocated
as any other forfeiture pursuant to applicable provisions of Section 4.6.
Notwithstanding the preceding sentence, if the Participant or Beneficiary files
a valid claim pursuant to Section 6.10 for the forfeited benefits payable under
the Plan, then (i) as soon as administratively practicable, the forfeited
benefits payable to such Participant or Beneficiary

                                     VI-17
<PAGE>

shall be reinstated effective as of the date of receipt of the claim and (ii) as
soon as administratively practicable following an Employer's Contribution
(pursuant to applicable provisions of Section 3.4) of an amount equal in value
to the value of such forfeited benefits, the value of the reinstated benefits
shall be paid pursuant to Section 6.6.

     Should the Plan be joined as a part to any escheat proceedings concerning
rights to any benefits payable to a Participant or Beneficiary thereof, the Plan
shall comply with any final judgment (of the appropriate court declaring that
title to any benefits payable under the Plan to a Participant or Beneficiary
thereof vests in the State) by (i) treating the judgment as if it were a claim
filed by the Participant or Beneficiary thereof on the effective date of the
final judgment and (ii) paying the State as if it were the Participant or
Beneficiary who filed the claim for benefits which the court determined have
escheated to the State.

     6.8. Withdrawals by Participants:
          ---------------------------

          (a)  Withdrawal of Employer Contributions: Subject to the conditions
               ------------------------------------
     of this Section, upon giving thirty (30) days' written notice to the
     Committee, any Participant who has withdrawn the maximum permissible amount
     under Section 6.8(b) and (i) who has attained age 59 1/2 and has been a
     Participant for at least five (5) years, or (ii) who is suffering an
                                              --
     immediate and heavy financial hardship (a) because of expenses previously
     incurred, or necessary to be incurred, for medical care described in
     Section 213(d) of the Code (not covered by insurance or otherwise
     reimbursable from any other source) of the Participant, the Participant's
     spouse or any other person who qualifies as a dependent of the Participant
     under Section 152 of the Code, (b) due to lack of funds required to pay
     expenses and/or other amounts required (excluding mortgage payments) to
     effect the purchase of a principal residence for the Participant, (c) due
     to a lack of funds required to make any payment required to avoid eviction
     from the Participant's principal residence, (d) due to lack of funds
     required to make any payment required to avoid foreclosure on the
     Participant's principal residence, or (e) due to a lack of funds to pay
     amounts demanded by the trustee in bankruptcy or other appropriate
     representative of the Participant's creditors in any bankruptcy, insolvency
     or similar proceeding in which the Participant's Account is properly
     subject to claims of such creditors as required by applicable law, shall be
     entitled to withdraw from his Account, in the order of priority set out
     below, an amount equal to the lesser of (A) the amount needed to alleviate
     the hardship or (B) the Distributable Amount (defined below) then credited
     to the Participant's Account. Any Participant who has attained age 59 1/2,
     but who has not been a Participant for at least five (5) years, and who is
     not making a hardship withdrawal described in the immediately preceding
     sentence, shall be entitled to make a withdrawal from his Employer Account
     in the same amount as set forth in the immediately preceding sentence, and
     priority as set forth in second paragraph below, except that such
     Participant shall be entitled to withdraw only those vested Matching
     Contributions (and any earnings attributable thereto) which have been
     credited to the Participant's Account for at least two (2) years before the
     withdrawal. The requested withdrawal under clause (A) above may include an
     additional amount necessary to pay any federal, state or local income taxes
     or penalties (including additional taxes under Section 72(t) of the Code)
     that are reasonably

                                     VI-18
<PAGE>

     expected to result from the withdrawal. For purposes of clause (B) above in
     accordance with Section 1.401(k)-1(d)(2)(ii) of the income tax regulations,
     the Distributable Amount shall be equal to the Participant's total Elective
     Contributions credited to his Employer Nonforfeitable Contributions Account
     as of the date of withdrawal; provided, however, the Distributable Amount
     shall be increased by any Qualified Non-Elective Contributions and net
     earnings and appreciation on Elective Contributions and Qualified Non-
     Elective Contributions that were credited to the Participant's
     Nonforfeitable Contributions Account as of December 31, 1988. The
     Distributable Amount shall not include any (i) Qualified Non-Elective
     Contributions and (ii) earnings and appreciation, that were credited to the
     Participant's Nonforfeitable Contributions Account after December 31, 1988.
     Effective December 1, 1996, the Distributable Amount shall include the
     Participant's Rollover Contributions Account.

          Except as may otherwise be prescribed by the Committee under
     nondiscriminatory rules uniformly applied and announced to Participants,
     withdrawals permitted hereunder shall be made in the following order:

          (i)    the Employee Account, if any;

          (ii)   the Rollover Account, if any;

          (iii)  the Employer Contributions Account whereunder the Participant
                 shall effect such withdrawal

                 (1)  from amounts attributable to any predecessor Profit
                      Sharing and Savings Plan Contributions and any income and
                      increments thereon;

                 (2)  from any Profit Sharing Contributions and any income and
                      increments thereon; and lastly

                 (3)  from any Matching Contributions and any income and
                      increments thereon.

          (iv)   the Employer Nonforfeitable Contributions Account whereunder
                 the Participant shall effect withdrawal

                 (1)  from amounts attributable to any Qualified Non-Elective
                      Contributions and any income and increments thereon;

                 (2)  from any Profit Sharing Contributions and any income and
                      increments thereon;

                 (3)  from any income or increment on Elective Contributions;
                      and lastly

                                     VI-19
<PAGE>

                 (4)  from any Elective Contributions.

     The entire withdrawable balance then credited to the applicable account
     described in the preceding sentence must be withdrawn before withdrawals
     may be made from the succeeding account. All other amounts credited to such
     Participant's Account and not withdrawn shall remain in such Participant's
     Account.

          If such withdrawal is made at a time when the member is not fully
     vested in the portion of his Employer Contributions Account and such
     Participant can increase his vested percentage in his Employer
     Contributions Account, such Participant's vested interest in his Employer
     Contributions Account at any relevant time will be determined under the
     following formula: X = P(AB + D)-D. For purposes of applying the formula: P
     is the vested percentage at the relevant time; AB is an Employer
     Contributions Account balance at the relevant time; and D is the amount of
     the withdrawal.

          A Participant shall not be considered as suffering an immediate and
     heavy financial hardship unless such Participant submits to the Committee
     (i) written evidence (satisfactory to the Committee) of such hardship and
     the amount needed to alleviate the hardship (ii) any other written
     agreement or other documentation which the Committee deems to be necessary
     or appropriate in order to ensure that the Participant understands and will
     comply with the requirements of this Section. Absent actual knowledge to
     the contrary, any Participant shall be deemed to have met the requirements
     of the immediately preceding sentence if the Participant complies with the
     requirements of the immediately succeeding sentence and if he submits a
     written request in which he specifically identifies the hardship and
     attaches a photocopy of (i) bills for medical care (described in the first
     paragraph of this Section) previously incurred or physician's reports and
     other evidence of medical care to be incurred, (ii) a contract to purchase
     property which he represents to be his principal residence, (iii) a notice
     or other evidence of imminent eviction from property which the Participant
     represents to be his principal residence, (iv) a notice or other evidence
     of imminent foreclosure action with respect to property which the
     Participant represents to be his principal residence, (v) a certified copy
     of the order of the court or other authority with jurisdiction over the
     trustee in bankruptcy or other appropriate representative of the
     Participant's creditors in any bankruptcy, insolvency or similar
     proceeding, to the effect that the amounts demanded by such trustee or
     other appropriate representative have been determined by such court or
     other authority to be due and payable to or for the benefit of such
     creditors, or (vi) other evidence of the claimed hardship and the amount of
     funds required to alleviate such hardship.

          In addition, the Participant must represent in writing that (i) his
     financial need cannot be relieved through reimbursement or compensation by
     insurance or otherwise, (ii) his financial need cannot be relieved through
     liquidation of any of his remaining assets (or any remaining assets of his
     spouse or minor children that are readily available to the Participant)
     without such liquidation itself causing an immediate and heavy

                                     VI-20
<PAGE>

     financial hardship, (iii) his financial need cannot be relieved through his
     cessation of any contributions made by or on behalf of such Participant to
     the Plan, (iv) such Participant has received or applied for all other
     distributions available to him from plans maintained by an Employer and any
     other employer, and such distributions have not or will not relieve the
     claimed financial hardship, and (v) such Participant has received or
     applied for all nontaxable loans available to him from plans maintained by
     an Employer or any other employer and from commercial sources, and such
     loans have not or will not relieve the claimed financial hardship. However,
     the purpose of permitting withdrawals under this Section is to reduce the
     specific need. Therefore, if requiring one of the actions listed in items
     (i) through (v) above would have the effect of increasing the amount
     needed, then the action will not be required. For example, if a participant
     needs funds to purchase a principal residence, but receiving a Plan loan
     would disqualify the employee from obtaining other necessary financing,
     then obtaining the Plan loan will not be required even though it is listed
     as item (v) above.

          The Committee shall have no duty or obligation to independently
     investigate or verify the truth or accuracy of any representation of the
     Participant or the authenticity or accuracy of any documentary evidence
     provided by the Participant and, absent actual knowledge to the contrary,
     the Committee shall assume that any such representation is true and correct
     and any such documentary evidence is authentic and correct.

          Any withdrawal hereunder shall result in suspension (for a period of
     12 months after the Participant's receipt of amounts withdrawn hereunder)
     of Elective Contributions and Employee Voluntary Contributions under the
     Plan and any elective deferrals (described in Section 402(g)(3) of the
     Code) and any employee contributions described in Section 401(m) of the
     Code under any other plan of deferred compensation maintained by an
     Employer and/or any Affiliated Employer. The term "any other plan of
     deferred compensation" as used in the immediately preceding sentence shall
     mean any plan of deferred compensation maintained by an Employer or any
     Affiliated Employer, including stock option, stock purchase and similar
     plans, as well as a cash or deferred arrangement under a cafeteria plan
     described in Section 125 of the Code, but excluding health or welfare
     benefit plans, and excluding the mandatory contributions portion of any
     defined benefit plan maintained by an Employer or any Affiliated Employer.
     Accordingly, as a prior condition of any hardship withdrawal, the
     Participant shall execute any written agreement or other document that the
     Committee deems necessary to ensure that during the one-year suspension
     period, the Participant is on notice and will comply with requirements of
     Section 401(k) of the Code.

          In addition, under the Plan and any other plan maintained by an
     Employer and/or any Affiliated Employer, the Participant may not authorize
     Elective Contributions or any other elective deferrals (described in
     Section 402(g)(3) of the Code) for the Participant's taxable year
     immediately following the taxable year of receipt of the amount withdrawn
     hereunder in excess of the applicable dollar limit under Section 402(g) of
     the Code for such next taxable year, less the amount of such Elective
     Contributions and any other

                                     VI-21
<PAGE>

     elective deferrals (described above) for the Participant's taxable year of
     receipt of the amount withdrawn hereunder.

          No withdrawal hereunder shall result in any forfeiture of a
     Participant's vested Account balance and no repayment of amounts withdrawn
     in order to wholly or partially restore a withdrawing Participant's Account
     shall be permitted.

          The Participant's Account shall be credited with the income of the
     Trust Fund pursuant to Section 4.4 until the day of withdrawal, as provided
     above. Amounts eligible to be withdrawn under this Section shall be made
     available as soon as practical after the Participant's withdrawal request
     is approved. No more than one withdrawal can be made during any quarter of
     a Plan Year.

          Subject to the requirements of Section 411(d)(6) of the Internal
     Revenue Code and regulations and other guidance issued thereunder by the
     Internal Revenue Service, to the extent that a Participant would be
     entitled to withdraw any portion of his Account balance (immediately prior
     to the most recent effective date of this Section 6.8(a)) under the
     provisions of this Section as in effect immediately prior to the most
     recent effective date of this Section, but may not withdraw such portion
     under the currently operative provisions of this Section, the provisions of
     this Section as in effect immediately prior to the most recent effective
     date of this Section shall apply with respect to the Participant's Account
     balance immediately prior to the effective date of this Section.

          (b)  Withdrawal of Participant Contributions: Subject to the
               ---------------------------------------
     conditions of this Section, each Participant, upon giving written notice to
     the Committee and the Trustee, shall be entitled to withdraw from his
     Employee Account an amount equal to the balance of such Employee Account.
     Any portion of the Participant's Employee Account that is derived from
     recharacterized Elective Contributions shall be subject to the same
     conditions, limitations and penalty provisions as are set out in Section
     6.8(a). The Participant's Employee Account shall be credited with the
     income of the Trust Fund in accordance with Section 4.4 until the day of
     withdrawal. The appreciation or depreciation of the Trust Fund and any
     understatement or overstatement of income shall be allocated as of the end
     of the Plan Year pursuant to Section 4.4 but based on only the income
     remaining in the Account after the withdrawal. Amounts eligible to be
     withdrawn under this Section 6.8(b) shall be made available as soon as
     practical after the Participant's withdrawal request is approved. No more
     than one withdrawal can be made during any quarter of a Plan Year.

     6.9. Claims Procedure for Benefits: When a benefit is due under the Plan,
          -----------------------------
a claim should be submitted to the personnel office of an Employer by which the
Participant is or was employed. Under normal circumstances a final decision on a
claimant's request for benefits shall be made within ninety (90) days after
receipt of the claim. However, if special circumstances require an extension of
time to process a claim, a final decision may be deferred up to one hundred
eighty (180) days after receipt of the claim if, prior to the end of the initial
ninety (90) day period, the claimant is furnished with written notice of the
special circumstances requiring

                                     VI-22
<PAGE>

the extension and the anticipated date of a final decision. If the claim is
denied, within the applicable period of time set out above, the claimant shall
receive written notification of the denial, which notice shall set forth the
specific reasons for the denial, the relevant Plan provisions on which the
denial is based, and the claim review procedure under the Plan. In the event
that a claim is denied, or in the event no action is taken on the claim within
the above-described period(s) of time, the following procedure shall be used:

          (a)  First, in the event that the claimant does not timely receive the
     above-described written notification, the claimant's request for benefits
     shall be deemed to be denied as of the last day of the relevant period and
     the claimant shall be entitled to a full review of his claim in accordance
     with the following provisions of this Section.

          (b)  Second, a claimant is entitled to a full review of his claim
     after actual or constructive notification of a denial. A claimant desiring
     a review must make a written request to the Committee requesting such a
     review, which may include whatever comments or arguments the claimant
     wishes to submit. Incident to the review, the claimant may represent
     himself or appoint a representative to do so, and will have the right to
     inspect all documents pertaining to the issue. The Committee, in its sole
     discretion, may schedule any meeting(s) with the claimant and/or the
     claimant's representative that it deems necessary or appropriate to
     facilitate or expedite its review of a denied claim.


A request for a review must be filed with the Committee within ninety (90) days
after the denial of the claim for benefits was actually or constructively
received by the claimant. If no request is received within the 90-day time
limit, the denial of benefits will be final. However, if a request for review of
a denied claim is timely filed, the Committee must render its decision under
normal circumstances within sixty (60) days of the receipt of the request for
review. In special circumstances the decision may be delayed if, prior to
expiration of the initial 60-day period, the claimant is notified of the
extension, but must in any event be rendered no later than one hundred twenty
(120) days after the receipt of the request. If the decision on review is not
furnished to the claimant within the applicable time period(s) set above, the
claim shall be deemed denied on the last day of the relevant period. All
decisions of the Committee shall be in writing and shall include specific
reasons for whatever action has been taken, including the specific Plan
provisions on which the decision is based.

     6.10. Loans to Participants and Beneficiaries:
           ---------------------------------------

           (a)  Loans may be permitted from time to time, as determined by the
     Committee, to (i) any Participant or (ii) after October 18, 1989, any
     Participant's Beneficiary or alternate payee under a qualified domestic
     relations order described in Section 414(p) of the Code, who is a "party in
     interest", as defined in Section 3(14) of the Act, or a "disqualified
     person," as defined in Section 4975(e)(2) of the Code, and (iii) on whose
     behalf an Account or subaccount is maintained under the Plan (hereinafter
     an individual described in clause (i) or (ii) and (iii) shall be referred
     to as a "Qualified Participant"). For purposes of this Section, a "loan"
     shall include any renewal or

                                     VI-23
<PAGE>

     modification to an existing loan hereunder so long as, at the time of any
     such modification or extension, the requirements of this Section are met.
     Any action taken by the Committee shall be taken pursuant to applicable
     provisions of Article VIII and shall be communicated to Qualified
     Participants at such time and in such manner as shall be prescribed by the
     Committee.

          In order to relieve any demonstrated financial hardship, as described
     under the provisions of the Plan which cover in-service withdrawals, or for
     any other suitable purpose (such as financing the purchase of a home or
     paying education expenses) as determined by the Committee and announced to
     Qualified Participants, a Qualified Participant may borrow from his vested
     Account balance under the Plan, subject to the following provisions of this
     Section and to such additional rules or guidelines as the Committee may
     adopt hereunder, by making prior written application to the Committee on
     forms provided for that purpose by the Committee. Such forms (hereinafter
     referred to as the "application forms") shall (i) specify the terms
     pursuant to which the loan is requested to be made, (ii) designate the
     extent, if any, that the loan will be made from any one or more of any
     funds as may have been established under Section 4.10 in which the
     Qualified Participant has an interest, (iii) authorize the repayment of the
     loan through payroll deductions in accordance with subsection (c) of this
     Section if the Qualified Participant is an Employee, or authorize a
     procedure whereby the Qualified Participant is to be invoiced monthly in
     accordance with subsection (c) of this Section if the Qualified Participant
     is not an Employee, (iv) provide such additional information and
     documentation (including but not limited to demonstration of financial
     hardship or any other suitable purpose of the loan) as the Committee shall
     require, and (v) include a note and security agreement, duly executed by
     the Qualified Participant, pursuant to which the Qualified Participant
     promises to repay the note and grants a security interest, as described in
     subsection (c) of this Section, to secure repayment of the loan and the
     note.


          (b)  The Committee shall issue rules or guidelines ("Standards") which
     shall not be inconsistent with applicable provisions of the Code and the
     Act, and regulations or other authority issued thereunder by the
     appropriate governmental authority and which shall be uniformly applicable
     to all Qualified Participants similarly situated and shall govern the
     Committee's approval or disapproval of completed application forms. Under
     such Standards, the Committee shall consider the Qualified Participant's
     creditworthiness and credit history, fair market value and liquidity of the
     Qualified Participant's collateral to be pledged as security for the loan,
     and any other factors which the Committee determines are considered in a
     normal commercial setting by a commercial lender. To the extent not
     inconsistent with the requirements of applicable provisions of the Code and
     the Act, the Standards shall prescribe the manner for determining the
     annual rate of interest to be charged on each loan to a Qualified
     Participant under the Plan. Without limiting the scope of the immediately
     preceding sentence, such annual rate of interest for such loans must
     provide the Plan with an annual rate of return commensurate with the
     prevailing interest rate charged on similar commercial loans by persons in
     the business of lending money for loans which would be made under similar
     circumstances. In addition, the Standards may provide for assessment of a
     fee for processing loan application forms,

                                     VI-24
<PAGE>

     obtaining credit reports, collection and processing late payments, and
     similar administrative expenses which amounts shall be charged directly to
     the Account of the affected Qualified Participant. The Committee shall from
     time to time prescribe such additional Standards that it deems to be
     necessary or appropriate and which are consistent with proper lending
     practices.

          (c)  To the extent that loans are permitted under this Section,
     subject to applicable provisions of this Section, following receipt by the
     Committee of a properly completed application form, each Qualified
     Participant who, pursuant to the above-described Standards, the Committee
     determines to be credit worthy and to be able to provide the requisite
     security shall be entitled to borrow from his Account an amount which (when
     added to the outstanding balance of all other loans to the Qualified
     Participant under all "qualified employer plans," as defined in Section
     72(p)(4) of the Code, of an Employer and any Affiliated Employers) is not
     in excess of the lesser of (i) $50,000, reduced by the excess, if any, of
     (a) the highest outstanding balance of such loans during the one-year
     period ending on the day before the latest date on which a loan was made,
     over (b) the outstanding balance of such loans on the latest date on which
     a loan was made, or (ii) one-half (1/2) of the present value of the vested
     account balance of the Qualified Participant under the Plan as of the most
     recent Valuation Date. Any renewal or modification of an existing loan
     hereunder shall be deemed to be a new loan for purposes of this Section.
     Any such loan shall be secured by such Qualified Participant's vested
     interest in his Account balance; provided however, with respect to any loan
     made after October 18, 1989, such security interest may not exceed one-half
     of such Account balance immediately after the origination of each loan
     hereunder. In addition, any loan originated, renewed or modified hereunder
     with respect to a Qualified Participant who is an Employee shall be repaid
     by payroll deduction pursuant to a substantially level amortization
     schedule as provided in the Standards issued by the Committee (with
     payments not less frequently than quarterly) over the term of the loan. Any
     such loan issued hereunder to a Qualified Participant who is not an
     Employee shall be repaid pursuant to a monthly invoice issued by the
     Committee requiring payment by the Qualified Participant within 30 days of
     the Qualified Participant's receipt of the monthly invoice and in
     accordance with a substantially level amortization schedule as provided in
     the Standards issued by the Committee (with payments not less frequently
     than quarterly) over the term of the loan. No loan shall have a maturity
     date in excess of five (5) years, unless the loan is used to acquire any
     dwelling unit which within a reasonable time is to be used (determined at
     the time the loan is made) as a principal residence of the Participant.

          Any loan may be prepaid without penalty, if the Qualified Participant
     repays the full amount of the loan, plus all interest accrued and unpaid
     thereon; provided, however, partial payments on a loan may be permitted by
     the Committee in the nondiscriminatory exercise of its discretion pursuant
     to rules established by the Committee which are applicable to similarly
     situated Qualified Participants.

                                     VI-25
<PAGE>

          Notwithstanding any other provision to the contrary, (i) no loan shall
     be made to any Qualified Participant who is or was either an "owner
     employee" or is a "shareholder employee" of any Employer that is an S
     corporation within the meaning of such terms under Section 4975(d) of the
     Code, (ii) no Qualified Participant shall be entitled to a loan from the
     Trust Fund if the amount of the loan is less than $1,000, except in the
     case of a loan for the purpose of paying amounts demanded in connection
     with any bankruptcy, insolvency or similar proceeding described in Section
     6.8(a), in which event, no minimum loan amount shall apply, and (iii) to
     the extent applicable, no Qualified Participant shall be entitled to a loan
     from the Trust Fund if the making of the loan would interfere with the
     orderly management of the Plan for the benefit of all the Qualified
     Participants or otherwise contravene any applicable law or regulation.

          (d)  After May 31, 1992, any loan or loans to a Qualified Participant
     hereunder shall not be made as an investment of the Trust Fund but instead
     shall be considered to be an earmarked investment of the Qualified
     Participant's Account. A subaccount shall be established for the Qualified
     Participant and shall be maintained until the loan or loans are repaid in
     full. Such loan or loans shall be the only investment of such subaccount
     and thus such subaccount shall not be taken into account for purposes of
     determining or allocating income, gains or losses of any commingled portion
     of the Trust Fund and all costs, charges, fees or expenses in connection
     with acquisition and disposition of such investment of the subaccount shall
     be charged directly to such subaccount; provided however, such subaccount
     shall not be charged with any portion of comparable costs, charges, fees or
     expenses incurred on behalf of Accounts which are part of the commingled
     portion of the Trust Fund.

          (e)  The Committee shall, in accordance with its established
     Standards, review and approve or disapprove completed application forms as
     soon as practicable after its receipt thereof, and shall promptly notify
     the applying Qualified Participant of the disposition of his application
     form. The Committee shall have the authority to delegate the power to
     review and approve or disapprove loans under this Section to such agents or
     committees composed of persons appointed by the Committee as the Committee
     shall deem proper, provided that any such agents or committees shall act
     only in accordance with the Standards established by the Committee pursuant
     to this Section. If the Trustee, in its sole discretion, determines that it
     is not reasonably and prudently able, in the interest of Qualified
     Participants, to liquidate the necessary amount from any funds that may
     have been established under Section 4.10, the Trustee shall notify the
     Committee, and the amount to be paid to each Qualified Participant whose
     completed application form designated that a loan be made from such fund
     shall be reduced in proportion to the ratio which the aggregate amount, if
     any, that the Trustee has advised the Committee may prudently be liquidated
     bears to the aggregate amount which all such Qualified Participants
     designated to be paid from such fund.

          (f)  Subject to subsection (e), the Committee, upon approval of a
     completed application, shall direct the Trustee to convert all or any part
     of the Qualified Participant's interest in the Trust Fund, or in each
     affected fund which may have been established

                                     VI-26
<PAGE>

     pursuant to Section 4.10, in the aggregate amount necessary to make payment
     of the loan proceeds from the Trust Fund, or each such fund as may have
     been established pursuant to Section 4.10, to the extent designated in the
     completed application form, and shall direct the Trustee to transfer cash
     to the Qualified Participant in such aggregate amount. The Committee shall
     maintain sufficient records to permit an accurate crediting of repayments
     of the loan in accordance with Subsection (j) of this Section.

          (g)  The unpaid balance owed by a Qualified Participant on a loan
     under the Plan shall not reduce the amount credited to his Account under
     the Plan. However, from the time of payment of the proceeds of the loan to
     the Qualified Participant, his Account balance shall be deemed invested, to
     the extent of such unpaid loan balance, in such loan until the complete
     repayment thereof or distribution from such Account. At the time a loan is
     made, the amount loaned shall

               (i)    first be deemed an investment of, and allocated to, the
                      Qualified Participant's Employer Nonforfeitable
                      Contributions Account to the extent that amounts allocated
                      thereto are not already allocated to a loan, assuming that
                      such loan is derived first from Elective Contributions and
                      any income and increments thereon; next, from any Profit
                      Sharing Contributions and any income and increments
                      thereon; and lastly, from any Qualified Non-Elective
                      Contributions and any earnings and increments thereon;
                      and

               (ii)   to the extent that such loan is in excess of such amounts,
                      it shall then be deemed an investment of, and allocated
                      to, the remaining vested portion of the Qualified
                      Participant's Employer Account to the extent that amounts
                      allocated thereto are not already allocated to a loan;
                      assuming that such loan is derived first from any Matching
                      Contributions and any income and increments thereon, and
                      next from the investment of amounts attributable to any
                      predecessor Profit Sharing and Savings Plan Contributions
                      and any income and increments thereon; and

               (iii)  to the extent that such loan is in excess of such amounts,
                      it shall then be deemed an investment of, and allocated
                      to, the Qualified Participant's Rollover Account, if any,
                      to the extent that amounts allocated thereto are not
                      already allocated to a loan; and

               (iv)   to the extent that such loan is in excess of such amounts,
                      it shall then be deemed an investment of, and allocated to
                      the Qualified Participant's Employee Account to the extent
                      that amounts allocated thereto are not already allocated
                      to a loan.

          (h)  Except in the event of application of a Qualified Participant's
     Account balance to repayment of a loan in the event of a default in
     accordance with subsection (k)

                                     VI-27
<PAGE>

     of this Section, no withdrawal may be made by a Qualified Participant under
     this Article VI of any amount deemed invested in the outstanding balance of
     any loan made pursuant to this Section.

          (i)  The amount of any distribution otherwise payable to a Qualified
     Participant shall be reduced by the amount owed (including any accrued
     interest) on all loans of the Qualified Participant at the time of such
     distribution. The Trustee shall apply the pledged portion of the Qualified
     Participant's Account to be distributed or paid toward the liquidation of
     the Qualified Participant's indebtedness to the Plan and the Trust Fund.
     Such reduction shall constitute a complete discharge of all liability to
     the Plan and the Trust Fund for the loan to the extent of such reduction.

          (j)  Repayment of all loans under the Plan shall be secured by the
     Qualified Participant's vested Account balance in accordance with
     applicable provisions of subsection (c) of this Section; provided, however,
     that repayment shall be secured by the Qualified Participant's vested
     interest in his Account only for such time, and to the extent that, a
     portion of such loan is allocated to such Account. Any loan repayment shall
     first be credited as soon as practicable to the Qualifying Participant's
     segregated subaccount and to that portion of the loan allocated to the
     Qualified Participant's individual accounts in the same order of priority
     as described in subsection (g) of this Section. Such credited amounts shall
     be transferred as soon as practicable following receipt thereof to the
     individual accounts of the Qualified Participant from which the assets were
     released upon establishment of the segregated subaccount, and shall
     thereafter be invested as part of the Trust Fund. A Qualified Participant
     may prepay his loan at any time, without penalty, provided that he pays the
     full amount of the loan, plus all interest accrued and unpaid thereon.

          With respect to any loan made prior to October 19, 1989, if, at any
     time prior to the full repayment of a loan to a Participant under the Plan,
     the Participant should cease to be a Participant by reason of his
     termination of employment for any reason, or the Plan should terminate, the
     unpaid balance owed by the Participant on the loan and all accrued but
     unpaid interest shall be due and payable immediately. With respect to any
     loan made after October 18, 1989, if the Qualified Participant should cease
     to be an Employee for any reason, but no distribution is made under the
     Plan with respect to such Qualified Participant, or if the loan is to a
     Qualified Participant who is a former Employee or a Beneficiary, and no
     distribution is made under the Plan with respect to such Qualified
     Participant, such Qualified Participant may make all repayments due on
     outstanding loans of such Qualified Participant by personal check or money
     order in accordance with the Qualified Participant's repayment schedule.
     Pursuant to applicable provisions of subsection (c), such repayment shall
     be made within 30 days of receipt of a monthly invoice.

          (k)  In the event of failure to make any payment of principal or
     interest under a loan when due, the loan shall be in default ("Default")
     and all the unpaid balance owed by the Qualified Participant and all
     accrued but unpaid interest shall be due and payable

                                     VI-28
<PAGE>

     immediately. Following a Default, the Committee and the Trustee may apply
     any pledged portion of the vested Account balance of the Qualified
     Participant to pay the loan, in whole or in part, and take any other action
     or remedy as allowed by law, provided that no application of a Qualified
     Participant's vested Account balance shall occur prior to the time such
     vested Account balance is otherwise distributable under the terms of the
     Plan, except as permitted by the Code and the Act. The amount of any
     withdrawal or distribution from the vested Account balance of a Qualified
     Participant or Beneficiary following a Default shall then be reduced by the
     amount of any loan in Default and such amount shall be applied to the
     unpaid loan balance and any accrued but unpaid interest thereon.

     6.11. Distributions to Divorced Spouse:  Subject to the provisions of
           --------------------------------
Section 12.3 which pertain to qualified domestic relations orders ("QDRO") and
pursuant to the qualified domestic relations order procedures of the Plan, in
the event that the Committee receives a domestic relations order that it
determines to be a valid QDRO, and if such QDRO provides that distribution of
vested benefits to an alternate payee described therein is not to commence or be
made immediately, but the QDRO provides for the apportionment of such benefits
to be made immediately, the Committee shall establish a separate account under
the Plan for the alternate payee.  Subject to Section 12.3 and the qualified
domestic relations order procedures of the Plan, if the Committee receives a
domestic relations order that it determines to be a valid QDRO, and if the QDRO
provides that distribution of vested benefits to an alternative payee described
therein is to commence or to be made immediately, then the Committee shall
direct the Trustee to effect distribution to the alternate payee who, for the
purpose of effecting such distribution, shall be considered and treated as any
other Participant who is entitled to receive the benefit payable under the Plan.

     If any such distribution is made at a time when the Participant is not
fully vested in the Participant's Employer Account and the Participant can
increase his or her vested percentage in such Employer Account, the
Participant's vested interest in his Employer Account shall be determined by the
following formula: X = P(AB + D)-D. For purposes of applying the formula: P is
the vested percentage at the relevant time; AB is an Employer Account balance at
the relevant time; and D is the amount of the distribution. For purposes of
allocating appreciation or depreciation of the Trust Fund and income or loss of
the Trust Fund, such distribution shall be subtracted from the Participant's
Account balance at the beginning of the Plan Year in which the distribution is
made.

     Notwithstanding the provisions of the preceding paragraph, the Committee
shall comply with the terms and provisions of any order which requires
distribution to an alternate payee prior to the affected Participant's "earliest
retirement age," as such term is defined in Section 206(d)(3)(E)(ii) of the Act
and Section 414(p)(4)(B) of the Code, if the order would have been determined to
be a valid QDRO if the order had required distribution at or after the
Participant's "earliest retirement date."

     6.12. Special Transition Rule:  Notwithstanding any other provisions of the
           -----------------------
Plan to the contrary, if the Plan is retroactively effective with respect to any
Plan Year (or other applicable

                                     VI-29
<PAGE>

accounting period) of a Prior Plan, the benefit payable under the Plan to any
Participant who terminated employment during such Plan Year (or other applicable
accounting period shall) be determined with reference to the special transition
rules of Sections 2.3, 4.12 and 12.5.

                           TOP-HEAVY PLAN PROVISIONS

     Capitalized terms used in this Article VII which are not otherwise defined
in Article I of the Plan are defined in Section 7.4.

     7.1. General Rules for Determining Top-Heavy Status:  In order to determine
          ----------------------------------------------
whether the Plan is Top-Heavy for a Plan Year, it is necessary to determine (i)
whether an Employer must be aggregated with other employers which will be
treated as a single employer, (ii) what the Determination Date is for the Plan
Year, (iii) which Employees or former Employees or other individuals who perform
or performed services as owners or employees of any Affiliated Employer which is
not an Employer (whether or not Qualified Plan participants) are, or formerly
were, Key Employees, (iv) which former Employees or other individuals who
performed services as owners or employees of any Affiliated Employer which is
not an Employer (whether or not Qualified Plan participants) have not performed
any service for an Employer (or any Affiliated Employer which is not an
Employer) at any time during the five-year period ending on the Determination
Date, (v) if, at any time during the five-year period ending on the
Determination Date, an Employer and the Affiliated Employers maintain or
maintained Qualified Plans (whether or not terminated) in addition to the Plan,
which Qualified Plans (including the Plan) are required or permitted to be
aggregated to determine Top-Heavy status and (vi) the present value of accrued
benefits (including distributions made during the plan year of the Qualified
Plan(s) and the four preceding plan years of the Qualified Plan(s)) of Key
Employees, former Key Employees and non-Key Employees.  For this purpose, an
Employer and all Affiliated Employers must be treated as one employer and the
Employees or former Employees or other individuals who perform or performed
services as owners or employees of any Affiliated Employer which is not an
Employer (whether or not participants in all Qualified Plans maintained by an
Employer and the Affiliated Employers) must be categorized as Key Employees,
former Key Employees or non-Key Employees.  Former Key Employees are non-Key
Employees and are excluded entirely from the calculation used to determine if a
plan or aggregation group of plans is Top-Heavy.

     With respect to plan years beginning after December 31, 1984, the accrued
benefit of any individual who has not performed any services for an Employer or
any Affiliated Employer at any time during the five-year period ending on the
Determination Date shall be excluded from the calculation used to determine if
the plan or aggregation group of plans is Top-Heavy. In addition, incident to
testing whether any such Plan or group of plans is Top-Heavy, an individual's
present value of accrued benefits is used only once. All Qualified Plans (of an
Employer and the Affiliated Employers) in which a Key Employee participates, and
certain other Qualified Plans, must be aggregated to form the Required
Aggregation Group. Other Qualified Plans may be aggregated with the Required
Aggregation Group to form a Permissive Aggregation Group. Once aggregated, all
Qualified Plans that are required to be aggregated will be Top-Heavy Plans only
if the aggregation group is Top-Heavy. No Qualified Plan in the Required
Aggregation Group will be Top-Heavy if the Required Aggregation Group is not
Top-Heavy. If a Permissive Aggregation Group is Top-Heavy, only those Qualified
Plans which are

                                     VII-1
<PAGE>

part of the Required Aggregation Group shall be treated as Top-Heavy Plans
subject to the provisions of this Article VII.

     7.2. Computation of Present Value of Accrued Benefits:

          (a)  Defined Contribution Plan(s):  The present value of accrued
               ----------------------------
     benefits as of the Determination Date for any individual who is a
     participant in a Qualified Plan which is (or is treated as) a defined
     contribution plan is the sum of (i) the account balance as of the most
     recent Valuation Date occurring within a 12-month period ending on the
     Determination Date, and (ii) an adjustment for contributions due as of the
     Determination Date. In the case of such a Qualified Plan not subject to the
     minimum funding requirements of Section 412 of the Code, the adjustment in
     (ii) is generally the amount of any contributions actually made after the
     Valuation Date but on or before the Determination Date. However, in the
     first plan year of the Qualified Plan, the adjustment in (ii) should also
     reflect the amount of any contributions made after the Determination Date
     that are allocated as of a date in that first plan year of the plan. In the
     case of a Qualified Plan that is a defined contribution plan and is subject
     to the minimum funding requirements, the account balance in (i) should
     include contributions that would be allocated as of a date not later than
     the Determination Date, even though those amounts are not yet required to
     be contributed. Thus, the account balance will include contributions waived
     in prior years as reflected in the adjusted account balance and
     contributions not paid that resulted in a funding deficiency. The adjusted
     account balance is described in Rev. Rul. 78-223, 1978-1 C.B. 125. Also,
     the adjustment in (ii) should reflect the amount of any contribution
     actually made (or due to be made) after the Valuation Date but before the
     expiration of the extended payment period in Section 412(c)(10) of the
     Code. The account balance of any individual who has not performed services
     for an Employer at any time during the 5-year period ending on the
     Determination Date shall be disregarded.

          (b)  Defined Benefit Plans:  The present value of an accrued benefit
               ---------------------
     under a Qualified Plan that is a defined benefit plan as of the
     Determination Date must be determined as of the most recent Valuation Date
     which is within a 12-month period ending on the Determination Date. In the
     first plan year of a plan, the accrued benefit for a current participant
     must be determined either (i) as if the individual terminated service as of
     the Determination Date (i.e., the last day of plan year of the plan) or,
     (ii) as if the individual terminated service as of the Valuation Date, but
     taking into account the estimated accrued benefit as of the Determination
     Date. However, for any other year, the accrued benefit for a current
     participant must be determined as if the individual terminated service as
     of such Valuation Date. For this purpose, the Valuation Date must be the
     same Valuation Date used for computing plan costs for minimum funding,
     regardless of whether a valuation is performed that year. For purposes of
     this paragraph, present value shall be determined with reference to the
     interest rate and mortality table used to determine Actuarial Equivalent
     optional benefits under the defined benefit plan. The accrued benefit of a
     Participant (other than a Key Employee) shall be determined (i) under the
     method which is used for accrual purposes for all plans of an Employer or
     (ii) or if there is no method described in clause (i), as if such benefit
     occurred not more

                                     VII-2
<PAGE>

     rapidly than the slowest accrual rate permitted under Section 411(b)(1)(c)
     of the Code. The accrued benefit of any individual who has not performed
     services for an Employer at any time during the 5-year period ending on the
     Determination Date shall be disregarded.

          (c)  Employee Contributions:  For purposes of determining the present
               ----------------------
     value of accrued benefits in either a defined benefit or defined
     contribution plan, the accrued benefits attributable to employee
     contributions are considered to be part of the accrued benefits whether
     such contributions are mandatory or voluntary. However, the amounts
     attributable to deductible employee contributions are not considered to be
     part of the accrued benefits.

          (d)  Distributions:  For purposes of determining the present value of
               -------------
     accrued benefits, distributions made within the plan year of the Qualified
     Plan that includes the Determination Date or within the four preceding plan
     years of such plan are added to the present value of accrued benefits in
     testing for top-heaviness. However, in the case of distributions made after
     the Valuation Date and prior to the Determination Date, such distributions
     are not included as distributions in Section 416(g)(3)(A) of the Code to
     the extent that such distributions are included in the present value of the
     accrued benefits as of the Valuation Date. In the case of the distribution
     of an annuity contract, the amount of such distribution is deemed to be the
     current actuarial value of the contract, determined on the date of the
     distribution. Benefits paid on account of death are treated as
     distributions hereunder to the extent such benefits do not exceed the
     present value of accrued benefits immediately prior to death.

          (e)  Rollover Contributions and Plan-to-Plan Transfers:  With respect
               -------------------------------------------------
     to proper treatment of rollover contributions and plan-to-plan transfers
     incident to determining the present value of accrued benefits, it must
     first be determined whether the rollovers and plan-to-plan transfers are
     unrelated (both initiated by the employee and made from a plan maintained
     by one employer to a plan maintained by another employer) or whether they
     are related (a rollover either not initiated by the employee or made to a
     plan maintained by the same employer). For purposes of determining whether
     the employer is the same employer, all employers aggregated under Section
     414(b), (c), (m) or (o) of the Code are treated as the same employer. Thus,
     an Employer and all Affiliated Employers are to be treated as a single
     employer. In the case of unrelated rollovers, (i) the plan providing the
     distributions shall count the distribution as a distribution under Section
     416(g)(3)(B) of the Code and (ii) the plan accepting the rollover shall not
     consider the rollover part of the accrued benefit if such rollover was
     accepted after December 31, 1983, but must consider it part of the accrued
     benefit if such rollover was accepted prior to January 1, 1984. In the case
     of related rollovers, the plan providing the rollover shall not count the
     rollover as a distribution under Section 416(g)(3)(B) of the Code and the
     plan accepting the rollover counts the rollover in the present value of the
     accrued benefits. Rules for related rollovers do not depend on whether the
     rollover was accepted prior to January 1, 1984. The provisions of this
     Section 7.2 shall not apply to direct rollovers described in Section
     6.6(c).

     7.3. Special Rules for Plan Years that Plan is Top-Heavy:  Notwithstanding
          ---------------------------------------------------
any other provision of the Plan and Trust to the contrary, if the Plan is Top-
Heavy for any Plan Year beginning after December 31, 1983, then the following
provisions shall be applicable and shall supersede and override any conflicting
provision of the Plan for such Plan Year:

          (a)  Vesting:  Vesting of accrued benefits (described in Section
               -------
     411(a)(7) of the Code, except those attributable to any Employee Voluntary
     Contributions, including benefits accrued before the effective date of
     Section 416 of the Code and benefits accrued before the Plan became Top-
     Heavy) under the Plan shall be determined in accordance with the vesting
     table set out in Section 6.4.

          (b)  Top-Heavy Compensation:  Considered Compensation and Top-Heavy
               ----------------------
     Compensation for any one Participant for such Plan Year in excess of (i)
     for Plan Years beginning on or after January 1, 1989, $200,000.00; and (ii)
     for Plan Years beginning on or after January 1, 1994, $150,000, as both of
     such dollar amounts are adjusted at such time and in such manner as is
     prescribed in Section 401(a)(17)(B) of the Code, shall be disregarded for
     any Plan Year in which the Plan is Top-Heavy.

          (c)  Minimum Allocations:  Subject to the following provisions hereof,
               -------------------
     for any Plan Year in which the Plan is Top-Heavy, each Participant shall
     receive an allocation of an Employer Contribution and forfeitures, if any,
     for the Plan Year in an amount equal to the lesser of (i) three percent
     (3%) of the Participants' Top-Heavy Compensation and (ii) the largest
     percentage of Top-Heavy Compensation provided on behalf of any Key
     Employee. The minimum allocation shall be made without regard to any
     contribution to Social Security. To the extent permitted under applicable
     law or other authority issued thereunder by the appropriate governmental
     authority, in determining whether an allocation of Employer Contributions
     equal to the required percentage of Top-Heavy Compensation meets the
     requirements of this Section, all benefits allocated under defined
     contribution plans required to be aggregated under Section 7.1 shall be
     considered benefits allocated under the Plan and, with respect to Plan
     Years beginning after December 31, 1984, any Employer Contribution
     attributable to a salary reduction or similar arrangement shall be taken
     into account. Accordingly, for the purpose of clarity and without limiting
     the scope of the immediately preceding sentence, (i) with respect to Plan
     Years beginning after December 31, 1988, any elective deferral (described
     in Section 402(g)(3) of the Code) under the Plan or any plan described in
     the immediately preceding sentence on behalf of any Participant who is not
     a key Employee shall not be treated as an Employer Contribution for
     purposes of this Section, but will be treated as an Employer Contribution
     for purposes of determining the percentage at which Contributions are made
     for the Key Employee with the highest percentage; (ii) qualified
     nonselective contributions (described in Section 401(m)(4)(C) of the Code)
     under the Plan or any plan described in the immediately preceding sentence
     on behalf of any Participant shall be treated as an Employer Contribution
     for purposes of this Section; and (iii) with respect to Plan Years
     beginning after December 31, 1988, any matching contribution (described in
     Section 401(m)(4)(A) of the Code) under the Plan or any plan described in
     the immediately preceding sentence on behalf of any Participant who is not
     a

                                     VII-4
<PAGE>

     Key Employee shall not be treated as an Employer Contribution for purposes
     of this Section to the extent such matching contribution is treated as an
     elective deferral for purposes of satisfying the actual deferral percentage
     test of Section 401(k)(3) of the Code or a matching contribution for
     purposes of satisfying the actual contribution percentage of Section
     401(m)(2) of the Code.

          Notwithstanding the preceding paragraph, in the event that an Employee
     is a Participant of the Plan and another Qualified Plan which is a defined
     benefit plan maintained by an Employer and/or any Affiliated Employer, such
     Employee shall not receive both the minimum benefit provided hereunder and
     the minimum benefit provided under the defined benefit plan on account of
     such plans being Top-Heavy. Instead, the aggregate minimum benefit
     requirement for any Employee who is a Participant under the Plan, and any
     defined benefit plan described in the preceding sentence, shall be provided
     under the defined benefit plan, which defined benefit minimum shall be
     offset by the value of the Participant's vested and nonforfeitable interest
     in his accrued benefit derived from Employer Contributions under the Plan.
     If the defined benefit minimum will be paid in the form of an annuity, the
     offset shall be effected by converting the Participant's vested accrued
     benefit derived from Employer Contributions under the Plan into an annuity
     (payable in the same form and commencing at the same time as the defined
     benefit minimum) which can be provided by the Participant's vested accrued
     benefit derived from Employer Contributions using the interest rate and
     mortality table for immediate annuities published by the Pension Benefit
     Guaranty Corporation as in effect on the date the defined benefit minimum
     is to commence. If the defined benefit minimum is paid in the form of a
     lump sum, the lump sum value of the Participant's accrued benefit derived
     from Employer Contributions under the Plan shall be offset against the
     single sum value of the defined benefit minimum calculated in accordance
     with the applicable provisions of the defined benefit plan. For purposes of
     this Section, a Participant's accrued benefit derived from Employer
     Contributions shall include any prior withdrawals or distributions
     attributable thereto.

          (d)  Special Rules:  For any Plan Year that the Plan is (i) Top-Heavy
               -------------
     and the additional minimum benefit described in Section 416(h) of the Code
     is not provided or (ii) Super Top-Heavy, the limitations of Section
     4.3(d)(iv) and (v) shall be applied by substituting "100 percent" for "125
     percent" wherever it appears therein. Such substitution shall not cause a
     reduction in any account balances attributable to Contributions for a Plan
     Year prior to the Plan Year in which the Plan is Top-Heavy or Super Top-
     Heavy.

     7.4. Definitions:  For purposes of this Article VII, the following terms
          -----------
shall be defined as follows:

          (a)  Affiliated Employer:  "Affiliated Employer" shall mean the
               -------------------
     Affiliated Employer described in Article I of the Plan.

                                     VII-5
<PAGE>

          (b)  Determination Date: "Determination Date" shall mean with respect
               ------------------
     to a single Qualified Plan, (i) the last day of the preceding plan year of
     the Qualified Plan, or (ii) in the case of the first plan year of the
     Qualified Plan, the last day of such plan year. When aggregating Qualified
     Plans, the value of accrued benefits will be calculated with reference to
     the Determination Dates that fall within the same calendar year.

          (c)  Employee:  "Employee" shall mean the Employee described in
               --------
     Article I of the Plan.

          (d)  Employer: "Employer" shall mean an Employer described in Article
               --------
     I of the Plan.

          (e)  Key Employee:  "Key Employee" shall mean with respect to any
               ------------
     Qualified Plan, any Employee or former Employee (or any other person (i)
     who is or was employed by any Affiliated Employer or (ii) who owns or owned
     any interest in any Affiliated Employer and who derives or derived earned
     income from such Affiliated Employer or would have derived earned income
     had such Affiliated Employer had net profits), including any beneficiary
     described below, who, at any time during the Qualified Plan's plan year
     containing the Determination Date or any of the four (4) preceding plan
     years of such Qualified Plan, is:

               (i)  An officer of any Employer or any Affiliated Employer
          treated separately, if such individual earns annual compensation for a
          plan year (for services rendered to an Employer and any Affiliated
          Employer during the relevant plan year of the Qualified Plan) greater
          than fifty percent (50%) of the amount in effect under Section
          415(b)(1)(A) of the Code as in effect for the calendar year in which
          such plan year ends for plan years beginning after December 31, 1986
          (one hundred fifty percent (150%) of the maximum dollar limitation set
          forth under Section 415(c)(1)(A) of the Code as in effect for the
          calendar year in which such plan year ends for plan years beginning
          prior to January 1, 1987); provided, however, subject to the last
          paragraph of this Section 7.4(e), no more than fifty (50) individuals
          who are or were Employees of an Employer and/or employees of an
          Affiliated Employer or, if less, the greater of three (3) individuals
          who are Employees of an Employer and/or employees of an Affiliated
          Employer or ten percent (10%) of all such individuals, shall be
          considered Key Employees by reason of being officers;

               (ii) One of the ten (10) individuals owning (or considered as
          owning within the meaning of Section 318 of the Code) both more than a
          1/2 percent interest and the largest interests in an Employer or any
          Affiliated Employer, treated separately, if such individual earns
          annual compensation for a plan year (for services rendered to an
          Employer and any Affiliated Employer during the relevant plan year of
          the Qualified
                                     VII-6
<PAGE>

          Plan) more than the maximum dollar limitation set forth under Section
          415(c)(1)(A) of the Code as in effect for the calendar year in which
          such plan year ends; provided, however, if two such individuals have
          the same interest in an Employer or Affiliated Employer, treated
          separately, the individual earning the greater compensation (for
          purposes of this Section 7.4(e)(ii)) shall be treated as having a
          larger interest;

               (iii) Any individual owning (or considered as owning within the
          meaning of Section 318 of the Code) more than five percent (5%) of the
          outstanding stock of any corporate Employer or any corporate
          Affiliated Employer treated separately, or stock possessing more than
          five percent (5%) of the total combined voting power of all stock of
          any corporate Employer or any corporate Affiliated Employer, treated
          separately, or, if an Employer or Affiliated Employer is not a
          corporation, any individual owning more than five percent (5%) of the
          capital or profits interest of such Employer, or Affiliated Employer
          treated separately; or

               (iv)  Any individual whose aggregate annual compensation for a
          plan year (for services rendered to an Employer and any Affiliated
          Employer during the relevant plan year of the Qualified Plan) is more
          than $150,000.00 and who would be described in Section 7.4(e)(iii) if
          one percent (1%) were substituted for five percent (5%) therein.

          Any Beneficiary of an Employee who is a Key Employee or a former Key
     Employee and any Beneficiary of any other individual described above who is
     a Key Employee or former Key Employee shall be treated as a Key Employee or
     former Key Employee, whichever is applicable. Similarly, any Beneficiary of
     an Employee who is a former non-Key Employee and any Beneficiary of any
     other individual described above who is a former non-Key Employee shall be
     treated as a former non-Key Employee.

          For purposes of applying Section 318 of the Code to the provisions of
     this Section, subparagraph (C) of Section 318(a)(2) of the Code shall be
     applied by substituting five percent (5%) for fifty percent (50%). For
     purposes of this Section, annual compensation for the plan year of the
     Qualified Plan shall include all remuneration described in Treasury
     Regulation Section 1.415-2(d) and any successor thereto, but including
     amounts contributed by an Employer or Affiliated Employer pursuant to a
     salary reduction agreement which are excludible from the individual's gross
     income under Section 125, Section 402(a)(8), Section 402(h) or Section
     403(b) of the Code.

     In the event that the number of Key Employees determined under Subsection
(e)(i) of this Section would, but for the numerical limitations of that
Subsection, exceed the number determined under that Subsection, then those
officers having the largest annual compensation during the plan year of the
Qualified Plan and the four (4) preceding plan years of such Qualified Plan
shall be the Key Employees.  Such term shall not include any officer or employee
of an entity referred to in Section 414(d) of the Code.  Notwithstanding any
provision hereof to the

                                     VII-7
<PAGE>

contrary, determination of who is a Key Employee shall be made in accordance
with Section 416(i)(1) of the Code and the regulations thereunder.

          (f)  Participant:  "Participant" shall mean any Participant described
               -----------
     in Article I of the Plan except that if the Plan is Top-Heavy, in addition
     to Employees who would otherwise be considered to be Participants under the
     Plan, the following Employees shall be considered to be Participants solely
     for purposes of determining the individuals entitled to share in the
     minimum benefit described in Section 7.3(c): (i) Participants who have not
     separated from service at the end of the Plan Year, (ii) individuals who
     are otherwise eligible to participate in the Plan but who have failed to
     complete 1000 hours of service (or the equivalent) during the Plan Year,
     (iii) individuals who are otherwise eligible to participate in the Plan but
     who declined to make any required Contributions to the Plan or, in the case
     of a cash or deferred arrangement, any elective contributions permitted or
     required under the Plan, or (iv) individuals who are eligible to
     participate in the Plan but who have been excluded from the Plan because
     each such individual's Considered Compensation is less than a stated
     amount.

          (g)  Permissive Aggregation Group:  "Permissive Aggregation Group"
               ----------------------------
     shall mean a Required Aggregation Group plus one or more Qualified Plans
     which are not part of the Required Aggregation Group but which satisfy the
     requirements of Section 401(a)(4) and 410 when considered together with the
     Required Aggregation Group.

          (h)  Qualified Plan:  "Qualified Plan" shall mean the Plan and any
               --------------
     other defined contribution plan (whether or not terminated) described in
     Section 414(i) of the Code and/or any defined benefit plan (whether or not
     terminated) described in Section 414(j) of the Code which is/are (or with
     respect to any such plan which has been terminated, was/were) maintained at
     any time during the five-year period ending on the Determination Date by an
     Employer and/or the Affiliated Employers and intended to meet the
     requirements of Section 401(a) of the Code; provided, however, a simplified

          --------------------------
Committee constitutes a quorum for the transaction of business. The majority
vote of the members present at any meeting called by the chairman of the

that meeting.  In addition, the Committee may decide any other question, which
is not brought before a meeting called by the chairman of the Committee, by a
majority vote taken of all of the members, or by a consent executed by a
majority of the members.

     8.5. Signatures:  The chairman, the secretary and any one or more of the
          ----------
members of the Committee to which the Committee has delegated the power, shall
each, severally, have the power to execute any document on behalf of the

     8.8.  Standard of Performance:  The Committee, and each of its members,
           -----------------------
shall (i) use the care, skill, prudence and diligence under the circumstances
then prevailing that a prudent man acting in a like capacity and familiar with
such matters would use in conducting his business as the administrator of the
Plan; (ii) when exercising its power to direct investments, diversify the
investments of the Plan so as to minimize the risk of large losses unless under
the circumstances it is clearly prudent not to do so; and (iii) otherwise act in
accordance with the provisions of the Plan and the Act.

     The Committee shall exercise its responsibility and authority hereunder in
a uniform and non-discriminatory manner with respect to all Participants.

Committee shall be liable for any act or omission of any other member of the
Committee, the Trustee, any investment manager appointed by the Committee, or
any other agent or representative appointed by the Committee, except to the
extent required by the Act, and any other applicable state or federal law, which
liability cannot be waived.  No member of the Committee shall be liable for any
act or omission on his own part except to the extent required by the Act, and
any other applicable state or federal law, and then only if and to the extent
such liability cannot be waived.  It is the express intent of the Plan to waive
any such liability to the fullest extent permitted by law.

     Further, it is specifically provided that, if directed by the Committee,
the Trustee may purchase out of the Trust Fund insurance for the members of the
Committee, any other fiduciaries appointed by the Committee, and for the Trust
Fund itself, to cover liability or losses occurring by reason of the act or
omission of any one or more of the members of the Committee or any other
appointed fiduciary under the Plan or any other agents; provided, however, such
insurance permits recourse by the insurer against the members of the Committee
or the other concerned fiduciaries in the case of a breach of a fiduciary
obligation by one or more members of the Committee or other fiduciary covered
thereby.

     8.10. Exemption from Bond:  No member of the Committee shall be required to
           -------------------
give bond for the performance of his duties hereunder, unless required by law
which cannot be waived.

           ---------------
its services, but shall be reimbursed by the Employer(s) for all expenses
properly and actually incurred in the performance of its duties under the Plan,
unless the Employer(s) elects to have such expenses paid out of the Trust Fund.
Each Employer shall bear such portion of such expense as shall be determined by
the Committee based upon the approximate total amount in the Accounts of
Participants employed by it as compared to the approximate total amount in the
Accounts of all Participants.

     8.12. Persons Serving in Dual Fiduciary Roles:  Any person, group of

Trustee and as a member of the Committee.

     8.13. Administrator:  For all purposes of the Act, the Administrator of the
           -------------
Plan shall be the Plan Sponsor.  The Administrator of the Plan shall have final
responsibility for compliance with all reporting and disclosure requirements
imposed with respect to the Plan under any applicable federal or state law, or
under any regulations or other authority promulgated thereunder by the
appropriate governmental authority.

     8.14. Indemnification of Participants of Committee.  To the full extent
           --------------------------------------------
permitted by law, the Plan Sponsor and each other Employer, jointly and
severally, shall indemnify each present and future member of the Committee
against, and each member of the Committee shall be entitled without further act
on his part to indemnity from each Employer for, any and all losses,
liabilities, costs and expenses (including the amount of judgments, court costs,
reasonable attorney's fees, and the amount of approved settlements made with a
view to the curtailment of costs of litigation, other than amounts paid to an
Employer itself) incurred by such member in connection with or arising out of
any pending, threatened or anticipated possible action, suit, or other
proceeding, including any investigation that might lead to such a proceeding, in
which he is or may be involved by reason of or in connection with his being or
having been a member of the Committee, whether or not he continues to be a
member of the Committee at the time of incurring any such losses, liabilities,
costs and expenses; provided, however, that such indemnity shall not include any
losses, liabilities, costs and expenses incurred by such member of the Committee
(i) with respect to any matters as to which he is finally adjudged in any such
action, suit or proceeding to have been guilty of gross negligence or willful
and culpable misconduct in the performance of his duties as a member of the
Committee, or (ii) with respect to any matter to the extent that a settlement
thereof is effected in an amount in excess of the amount approved by the Plan
Sponsor (or by the affected Employer if not an Affiliated Employer), which
consent shall not be unreasonably withheld.  No right of indemnification
hereunder shall be available to, or enforceable by, any such member of the
Committee unless, within sixty (60) days after his actual receipt of service of
process in any such action, suit or other proceeding (or such longer period as
may be approved by the Board), he shall have offered the Plan Sponsor (or
affected Employer if not an Affiliated Employer), in writing, the opportunity to
handle and defend same at its sole expense.  The decision by the Plan Sponsor or
other affected Employer to handle the proceeding shall conclusively determine
that such person is entitled to the indemnity provided herein unless then
otherwise expressly agreed by the person.  Until and unless a final judicial
determination has been made that indemnity is not applicable, all such person's
expenses shall be promptly and fully paid or reimbursed by the Plan Sponsor and
each other Employer upon demand by such person.  The foregoing right of
indemnification shall inure to the benefit of the heirs, executors,
administrators and personal representatives of each such member of the Committee
and shall be in addition to all other rights to which such member of the
Committee may be entitled as a matter of law, contract, or otherwise.

participate in any decisions pertaining solely to himself as a Participant or a
Beneficiary.

     9.2. Authority:  The Trustee shall also be a fiduciary and, in that
          ---------
capacity, shall have the exclusive responsibility for and all powers necessary
to receive, hold, preserve, manage, invest and reinvest the Trust Fund as

incident thereto.  However, if the Committee, as a co-fiduciary, or an
investment manager appointed by the Committee, shall exercise its power given
hereunder at any time, by written notice to the Trustee to direct the Trustee
(i) in the management, investment and reinvestment of the Trust Fund or (ii)
with respect to the transfer or acceptance of assets pursuant to Sections 1.1,
8.2(i), 8.2(j) or 11.7, then, in that event, the Trustee shall be subject to all
proper directions of the Committee or its appointed investment manager, provided

provisions of the Texas Trust Code, as amended from time to time, and all other
applicable laws, except such as conflict with the terms and provisions of the

     to keep any and all securities or other property in the name of some other

     with a power of attorney for their transfer attached, in bearer or Federal
     Reserve Book-Entry form, or in the name of the Trustee, without disclosing
     the fiduciary capacity of the Trustee;

     with respect to any investments held in the Trust Fund and to grant
     proxies, discretionary or otherwise, with or without the power of
     substitution, with respect thereto, but only according to the directions of
     the Committee or investment manager; or, to the extent that such rights are
     exercisable by Participants in the Plan, according to the directions of
     such Participants. The Trustee shall deliver or cause to be executed and
     delivered to the named fiduciary, all notices, prospectuses, finance
     statements, proxies and proxy soliciting materials relating to investments
     held hereunder. The Trustee shall not vote any proxy except in accordance
     with the timely written instructions of the Committee or the Investment
     Manger. If no such written instructions are received, such proxies shall
     not be voted.

          The Committee may assign to the Participants the right to vote
     proxies. To the extent the right to vote is vested in whole or in part in
     the Participants, the Trustee shall act in this regard only in accordance
     with the timely written instructions received from the Participants. Solely
     for this purpose, each Participant shall act as the named fiduciary in
     providing direction to the Trustee. To the extent practicable, all
     unallocated or unvoted shares held hereunder shall, solely for the purpose
     of this section, be voted in the same proportion as such Participant's
     allocated proportion of shares bear to the aggregate of all like shares for
     which instructions have been issued by the Participants as named
     fiduciaries to the Trustee.

     or before any body, board, agency, panel or tribunal;

          (f)  To hold uninvested at any time, without liability for interest
     thereon for a reasonable period of time, any amount of money received by

     otherwise until same can be reinvested or disbursed;

          (g)  To invest and reinvest the Trust Fund assets, or any part
     thereof, in any property of any kind or nature whatsoever, whether real,

     together with any amendments thereto, being hereby incorporated in and made
     a part of the Trust), in money market funds, or qualifying employer
     securities and/or qualifying employer real property of an Employer up to
     one hundred percent (100%) of the Trust Fund; provided, however, subject,
     with respect to periods beginning on and after August 1, 1996, to the right
     of the Committee under Section 4.10(c) of the Plan to override clause (i)
     below, (i) unless the Plan would not have to be registered under the
     federal Securities Act of 1933, only amounts attributable to Employer
     Contributions (other than Elective Contributions) shall be used to purchase
     qualifying employer securities and, (ii) to the extent the Trustee is not
     independent of the issuer of such employer securities, the issuer shall
     retain the services of an "agent independent of the issuer" (as such term
     is defined in Rule 10b-18 promulgated under the Securities Exchange Act of
     1934) to effect such purchase and, further provided, that the purchases are
     made in
     accordance with the provisions of the Act.

          (h)  To lease and let all or any portion of the properties possessed

     Trust), and for such consideration or royalties as the Trustee deems
     proper;

          (i)  To borrow from or loan such sums as the Trustee considers
     necessary or desirable (but not including loans to members without the
     express direction from the Committee) and, for that purpose, to mortgage or
     pledge all or any part of the Trust Fund property;

          (j)  If specifically directed in writing by the Committee, to purchase

<PAGE>

     under any such contract shall be made in contravention of applicable
     provisions of the Plan; and

          (k)  To employ such lawyers, accountants, actuaries, brokers, banks,
     investment counsel or other agents or employees and to delegate to them
     such duties, rights and powers of the Trustee hereunder (including the
     power to vote shares of stock) as the Trustee deems advisable in
     administering the Trust Fund.

The Trustee shall not be required to take any legal action to collect, preserve
or maintain any Trust Fund property unless the Trustee has been indemnified
either by the Trust itself, with the approval of the Committee, or by an
Employer, with respect to any expenses or losses to which the Trustee may be
subjected by taking such action.  Any property acquired by the Trustee through
the enforcement or compromise of any claim the Trustee has as Trustee will
become a part of the Trust Fund.  The Trustee shall be responsible only for the
property actually received by it hereunder.  It shall have no duty or authority
to compute any amount to be paid to it by an Employer or a Participant, or to
bring any action or proceeding to enforce the collection of any contribution to
the Trust Fund.

     9.4. Voting Company Stock:  This Section applies in the event that common
          --------------------
stock of the Plan Sponsor ("Company Stock") is authorized by the Committee,
pursuant to Section 4.10, for investment through a fund ("Company Stock Fund")
under which shares of Company Stock are allocated to the Accounts of
Participants and Beneficiaries who, pursuant to the Plan, direct the Trustee to
invest in the Company Stock Fund.

          (a)  Registration-Type Class of Securities:  During such time as the
               -------------------------------------
     Plan Sponsor has a "registration-type class of securities" (defined below),
     each Participant or Beneficiary, as applicable, will be entitled to
     instruct the Trustee on how to vote the shares of Company Stock allocated
     to his Account on the record date of each annual or special meeting of the
     Plan Sponsor's shareholders. For purposes of the Plan, in accordance with
     Section 409(e)(4) (or any successor provision) of the Code, the term
     "registration-type class of securities" means: a class of securities (1)
     required to be registered under Section 12 of the Securities Exchange Act
     of 1934 (the "Exchange Act") or (2) that would be required to be so
     registered except for the exemption from registration provided in
     subsection (g)(2)(H) of Section 12 of the Exchange Act.

          (b)  No Registration-Type Class of Securities:  If the Plan Sponsor
               ----------------------------------------
     does not have a "registration-type class of securities" (defined in (a)
     above), each Participant or Beneficiary, as applicable, shall be entitled
     to instruct the Trustee on how to vote the shares of Company Stock
     allocated to his Account on the record date of each annual or special
     meeting of the Plan Sponsor's shareholders, but only with respect to the
     approval or disapproval of any corporate merger or consolidation,
     recapitalization, reclassification, liquidation, dissolution, sale of
     substantially all assets of a trade or business, or any such similar
     transaction as shall be prescribed by the Secretary of the Treasury in
     regulations

                                     IX-4
<PAGE>

     or other authority issued under Section 409(e)(3) (or any successor
     provision) of the Code.

          With respect to all matters involving the voting of Company Stock not
     described in the immediately preceding paragraph, unless the Committee
     determines otherwise, all Company Stock held in the Trust Fund (both
     allocated and any unallocated shares) shall be voted by the Trustee in
     accordance with the Committee's instructions. The Committee may, in its
     discretion pursuant to Sections 405(c) and 404(a)(1) of the Act, delegate
     any power or duty allocated to it pursuant to immediately preceding
     sentence to another person or entity who, with the consent of such other
     person or entity, shall act as an independent fiduciary and shall exercise
     such power or duty to the same extent as it could have been exercised by
     the Committee. The persons or entities to which such powers and duties may
     be delegated shall include, without limitation, the Board or any committee
     of the Board, the Trustee, any person or entity that meets the requirements
     of an investment manager under Section 3(38) of the Act, or any other
     person or entity that the Committee determines in good faith has the
     requisite knowledge and experience concerning the matter with respect to
     which the delegation is made. The Committee may in its discretion remove
     any fiduciary to whom it has delegated any power or duty and exercise such
     power or duty itself or appoint a successor fiduciary.

          (c)  Voting Procedure:  Before each annual or special meeting of the
               ----------------
     Plan Sponsor's shareholders, the Committee shall direct the Trustee to send
     to each Participant and Beneficiary who is entitled to exercise voting
     rights, as provided in this Section, a copy of the proxy solicitation
     materials therefor, together with a form requesting confidential, written
     instructions on how to vote the shares of Company Stock allocated to his
     Account with respect to such matters on which he is entitled to vote. The
     proxy solicitation materials described in the preceding sentence shall be
     the same as those for shareholders of Company Stock generally, and shall
     comply with applicable state and federal law and the Plan Sponsor's charter
     and bylaws as generally applicable to shareholders of Company Stock. The
     Trustee shall not make recommendations to Participants and Beneficiaries on
     whether to vote or how to vote. The individual instructions received by the
     Trustee shall be held in strict confidence and shall not be divulged or
     released to any person, including Employees of any Employer or Affiliated
     Employer; provided, however, the Trustee shall advise any officer of the
     Plan Sponsor, at any time upon request, of the total number of shares of
     Company Stock that it has been instructed to vote in favor of each matter
     for which a vote was solicited, the total number of shares of Company Stock
     that it has been instructed not to vote in favor of each such matter and
     the total number of shares in respect of which it has received no
     instructions.

          (d)  Voting by Trustee Proportionate to Direction:  The Trustee shall
     aggregate the instructions timely received pursuant to (c) above and vote
     allocated whole shares of Company Stock and, to the same extent permitted
     for shareholders of the Plan Sponsor generally, allocated fractional shares
     of Company Stock specifically in accordance with the valid instructions so
     received from the Participants and Beneficiaries or from the

                                     IX-5
<PAGE>

     Committee (or its delegate), pursuant to subsections (a) or (b) above as
     applicable. Additionally, the Trustee shall vote any whole shares, an d
     fractional shares to the extent permitted, of Company Stock allocated to
     the Accounts for which it does not receive valid instructions in the same
     proportion as are voted the shares of Company Stock allocated to the
     Accounts with respect to which the Trustee has received valid instructions
     from the Participants and Beneficiaries or from the Committee (or its
     delegate), pursuant to subsections (a) or (b) above as applicable.

     9.5. Tender Offer for Company Stock.  This Section applies in the event
          ------------------------------
that common stock of the Plan Sponsor ("Company Stock") is authorized by the
Committee, pursuant to Section 4.10, for investment through a fund ("Company
Stock Fund") under which shares of Company Stock are allocated to the Accounts
of Participants and Beneficiaries who, pursuant to the Plan, direct the Trustee
to invest in the Company Stock Fund.  For purposes of this Section, "Tender
Offer" shall collectively mean (i) a cash tender offer, which includes a tender
offer for, or request or invitation for tenders of, shares of Company Stock in
exchange for cash, as made to the Trustee or to the shareholders of Company
Stock generally, and (ii) an exchange offer, which includes a tender offer for,
or request or invitation for tenders of, any shares of Company Stock in exchange
for any consideration other than all cash, as made to the Trustee or to the
shareholders of Company Stock generally.

          (a)  Allocated Shares of Company Stock:  In the event of a Tender
               ---------------------------------
     Offer, the Committee shall direct the Trustee to take those steps
     reasonably necessary to furnish information to, and request instructions
     from, each Participant or Beneficiary, as applicable, who has shares of
     Company Stock allocated to his Company Stock Account in substantially the
     same manner as with respect to the shareholders of Company Stock generally.
     In that regard, the Trustee shall:

               (i)   Inform each Participant (or Beneficiary) as to the
          existence of the Tender Offer; however, the Trustee shall not make any
          recommendations with respect to such Tender Offer;

               (ii)  Transmit to each Participant (or Beneficiary) such written
          information and other materials relative to the Tender Offer as are
          made available by the persons or entities making such Tender Offer to
          the shareholders of Company Stock generally;

               (iii) Request written instructions from each Participant (or
          Beneficiary) as to whether or not to tender or exchange the shares of
          Company Stock allocated to his Account; and

               (iv)  Use reasonably diligent efforts to effect, on a
          nondiscriminatory basis, the tender or exchange of allocated shares of
          Company Stock in accordance with the written instructions received
          from the Participants and Beneficiaries.

                                     IX-6
<PAGE>

          The number of shares to which a Participant's (or Beneficiary's)
     instructions apply will be the total number of shares allocated to his
     Account, regardless of whether the shares are vested, as of the close of
     business on the day preceding the date on which the tender offer commences.
     In accordance with the terms and conditions of the Tender Offer, the
     Trustee will tender or exchange those shares of Company Stock that it has
     been properly instructed to tender or exchange, and it will not tender or
     exchange those shares that it has not been properly instructed to tender or
     exchange. Instructions to the Trustee from a Participant or Beneficiary to
     tender or exchange shares will not be deemed a withdrawal or suspension
     from the Plan or a forfeiture of any portion of such person's interest in
     the Plan. Shares of Company Stock which are not tendered or exchanged
     pursuant to valid instructions shall remain invested in Company Stock.

          The individual instructions received by the Trustee shall be held in
     strict confidence and shall not be divulged or released to any person,
     including Employees of any Employer or Affiliated Employer; provided,
     however, the Trustee shall advise any officer of the Plan Sponsor, at any
     time upon request, of the total number of shares of Company Stock that it
     has been instructed to tender or exchange, the total number of shares that
     it has been instructed not to tender or exchange and the total number of
     shares for which it has received no instructions.

          (b)  Fractional and any Unallocated Shares of Company Stock:  The
               ------------------------------------------------------
     Trustee shall accumulate all fractional shares of Company Stock allocated
     to the Accounts and tender or exchange such fractional shares in the same
     proportion as the whole shares of Company Stock allocated to the Accounts
     (for which the Trustee received valid instructions to tender or exchange)
     were tendered or exchanged pursuant to subsection (a) above. Likewise, the
     Trustee shall tender or exchange any unallocated shares of Company Stock
     held in the Trust Fund in the same proportion as the whole shares of
     Company Stock allocated to the Company Stock Accounts (for which the
     Trustee received valid instructions to tender or exchange) were tendered or
     exchanged pursuant to subsection (a) above. Any shares of Company Stock
     which are not tendered or exchanged pursuant to the provisions of this
     subsection (b) shall remain invested in Company Stock.

          (c)  Funds Received for Tendered Company Stock:  Cash or other
               -----------------------------------------
     consideration received in exchange for tendered or exchanged Company Stock
     shall be held in accordance with Section 4.10(a) pending instructions from
     the Committee.

     9.6. Standard of Performance:  The Trustee in discharging the duties of
          -----------------------
Trustee with respect to the management, investment and reinvestment of the Trust
Fund assets shall do so solely in the interest of the Participants and
Beneficiaries, using the care, skill, prudence and diligence under the
circumstances then prevailing that a prudent man acting in a like capacity and
familiar with such matters would use in the conduct of an enterprise of a like
character; shall diversify the investments of the Trust Fund so as to minimize
the risk of large losses unless

                                     IX-7
<PAGE>

under the circumstances it is clearly prudent not to do so; and shall otherwise
act in accordance with the provisions of the Plan and the Act.

     9.7.  Liability for Investments:  The Trustee shall not be liable to the
           -------------------------
Trust, or to any person or entity having a beneficial interest in the Trust, for
any loss or decline in value which may be incurred upon any investment of the
Trust Fund assets, including, but not limited to, qualifying employer securities
and qualifying employer real property, or for failure of such assets to produce
any or greater earnings, interest, or profits, so long as the Trustee acts in
good faith and in accordance with the responsibilities, obligations and duties
placed on the Trustee under the Plan and the Act.

     9.8.  Reliance on Directions:  When the Trustee acts in good faith, the
           ----------------------
Trustee, in all matters pertaining to the Trustee's management and investment of
the Trust Fund, may rely upon any notice, resolution, instruction, direction,
order, certificate, opinion, letter, telegram or other document believed by the
Trustee to be genuine, to have been signed by a proper representative of the
Committee or an investment manager, if one is appointed, and to be the act of
the Committee or the investment manager, as the case may be.  The Trustee shall
accept any certificate or other instrument duly signed by a proper
representative of the Committee or an investment manager, if one is appointed,
which purports to evidence an instruction, direction, or order of the Committee
or the investment manager, as the case may be, as conclusive evidence thereof.

     9.9.  General Liability of the Trustee:  The Trustee shall not be liable
           --------------------------------
for any act or omission by the Trustee because of a direction of the Committee
or an investment manager appointed by the Committee; nor for any act or omission
of the Committee, an investment manager appointed by the Committee, or any other
agent appointed by the Committee, except to the extent required by the Act and
any other applicable state or federal law, which liability cannot be waived. The
Trustee shall not be liable for any act or omission on the Trustee's own part
except to the extent required by the Act and any other applicable state or
federal law, which liability cannot be waived. Further, it is specifically
provided that the Trustee may, with the written approval of the Committee,
purchase out of the Trust Fund insurance for the Trustee and for the Trust Fund
itself to cover liability and losses occurring by reason of the act or omission
of the Trustee, provided that such insurance permits recourse by the insurer
against the Trustee in the case of a breach of a fiduciary obligation by the
Trustee.

     9.10. Proof of Trustee's Authority:  All persons dealing with the Trustee
           ----------------------------
are entitled to rely upon the representations of the Trustee as to the Trustee's
authority and are released from any duty to inquire into the Trustee's authority
for taking or omitting any action, or to verify that any money paid for other
property delivered to the Trustee is used by the Trustee for Trust purposes.
Any action of the Trustee under the Plan shall be conclusively evidenced for all
purposes by a certificate or other document signed by the Trustee, and any such
certificate or document shall be conclusive evidence of the facts recited
therein.  Any person shall be fully  protected when acting or relying upon any
notice, resolution, instruction, direction, order,

                                     IX-8
<PAGE>

certificate, opinion, letter, telegram or other document believed by such person
to be genuine, to have been signed by the Trustee, and to be the act of the
Trustee.

     9.11. Accounting Required by Trustee.  Within a reasonable time (as
           ------------------------------
determined in the sole discretion of the Committee) after the close of each Plan
Year, and at such other times (or shorter accounting periods) as requested in
writing by the Committee, and as of the date of the removal or resignation of
the Trustee, the Trustee shall render to each Employer and the Committee, an
accounting report of the Trust Fund covering the period since the previous
accounting report.  The report shall reflect the transactions, expenses, and
earnings or losses for the period covered, and, as of the last day of such
period, the cost basis of the assets, the fair market value of the assets, and
the liabilities of the Trust Fund.  The written approval of such accounting
report by the Committee or the affected Employer, or the failure of the
Committee or the affected Employer to notify the Trustee of its disapproval of
such report within ninety (90) days after receipt thereof, shall be final and
binding as to the Trustee's administration of the Trust for such period upon
such Employer and all Participants (and Beneficiaries thereof) of such Employer
who have or may thereafter have an interest in the Trust, except with respect to
(i) any matter that the Committee or affected Employer could not reasonably be
expected to discover upon review of such accounting report, (ii) any actions or
omissions in violation of the Act or other applicable law, and (iii) any actions
or omissions that are determined by a court of competent jurisdiction to
constitute gross negligence or intentional or willful misconduct.

     9.12. Resignation or Removal of Trustee:  The Trustee may resign at any
           ---------------------------------
time by giving at least sixty (60) days prior written notice to the Board,
unless the Board agrees to a shorter notice period.  The Board may remove the
Trustee at any time by giving at least thirty (30) days prior written notice to
the Trustee, unless the Trustee agrees to a shorter notice period.  Upon the
resignation or removal of the Trustee, the Trustee shall render to the Committee
and to each Employer a written account of the administration of the Trust for
the period following the period that was covered by the last accounting report.

     Notwithstanding any provision of this Plan, it is agreed that in the event
of the resignation or removal of the Trustee, the Board shall promptly appoint a
successor. If no appointment of a successor is made by the Board within sixty
(60) days after the resignation or removal of the Trustee, after notice to the
other party, the Trustee may apply to any court of competent jurisdiction for
appointment of a successor. The Trustee shall be entitled to reasonable
compensation and reimbursement for costs associated with bringing such action.
The Trustee shall be furnished with written notice from the Plan Sponsor or the
court, as the case may be, of the appointment of the successor, and shall also
be furnished with written evidence of the successor's acceptance of trusteeship.

     9.13. Appointment and Power of Successor Trustee:  Any vacancy in the
           ------------------------------------------
office of Trustee created by the resignation or removal of the Trustee shall not
terminate the Trust.  In the event of any such vacancy, the Board shall appoint
a successor Trustee.  Any successor Trustee, after acknowledging acceptance of
the Trust and accepting the Trust Fund assets and liabilities and the accounting
of the retiring Trustee, shall be vested with all the estates, titles, rights,

                                     IX-9
<PAGE>

powers, duties, and discretions which were granted to the retiring Trustee. The
retiring Trustee shall execute and deliver all assignments or other instruments
as may be necessary or advisable in the discretion of the successor Trustee.

     9.14. Compensation of Trustee:  Any corporate Trustee shall be reimbursed
           -----------------------
for expenses properly and actually incurred in the performance of its duties
under the Plan and shall receive reasonable compensation for services rendered
as may be agreed upon, from time to time, between the Trustee and the Committee
with the consent and approval of the Board.  Any individual serving as Trustee
shall not receive any compensation for his services, but shall be reimbursed for
all expenses properly and actually incurred in the performance of his duties
under the Plan.

     The Trustee's compensation, if any, and the expenses of the Trust shall be
paid by an Employer(s) unless an Employer elects to have the Trustee's
compensation and the expenses of the Trust paid out of the Trust Fund. Until
such compensation and expense is actually paid, it shall constitute a charge or
lien on the Trust Fund. Each Employer shall bear that portion of such
compensation and expense as shall be determined by the Committee based upon the
approximate total amount in the Accounts of Participants employed by it as
compared to the approximate total amount in the Accounts of all Participants.

     9.15. Bonding.  The Trustee and each other fiduciary pursuant to the Act,
           -------
except a bank, insurance company or another person or entity which is exempted
under the Act, shall be bonded in an amount not less than ten percent (10%) of
the amount of funds that such fiduciary handles; provided, however, the minimum
bond shall be $1,000 and the maximum bond shall be $500,000.  The amount of
funds handled shall be determined at the beginning of each Trust Year by the
amount of funds handled by each covered fiduciary and their predecessors, if
any, during the preceding Plan Year, or if there is no preceding Plan Year, then
by the amount of funds to be handled during the current Plan Year.  The bond
shall provide protection to the Trust against any loss by reason of the fraud or
dishonesty of the fiduciary acting alone or in connivance with others.  The
surety shall be a corporate surety company (as such term is used in Section
412(a)(2) of the Act), and the bond shall be in a form approved by the U.S.
Secretary of Labor in regulations or other authority issued under the Act.

     9.16. Assignment of Trusteeship.  No assignment (as defined in the
           -------------------------
Investment Advisors Act of 1940) of this Agreement shall be made by the Trustee
without the written consent of the Plan Sponsor; provided, however, that the
Trustee may assign this Agreement to another wholly-owned subsidiary of the
Trustee which is organized and chartered as a trust company if the Trustee first
gives the Plan Sponsor forty-five days advance notice and the Plan Sponsor does
not object within the forty-five day period.

                      ADOPTION OF PLAN BY OTHER EMPLOYERS

     10.1. Adoption Procedure:  Any business organization may, with the approval
           ------------------
of the Board, adopt the Plan for all or any classification of its Employees, as
permitted by Section 401(a) of the Code, by delivering to the Committee:

           (a)  A certified resolution or consent of the sole proprietor,
     managing partner(s) or board of directors (or equivalent governing
     authority) of the adopting Employer, or a duly executed adoption instrument
     (adopted and approved by the sole proprietor, managing partner(s) or board
     of directors (or equivalent governing authority) of the adopting Employer))
     setting forth its agreement to be bound as an Employer by all the terms,
     provisions, conditions and limitations of the Plan, except those, if any,
     specifically set forth in the adoption instrument;

           (b)  All information required by the Committee and the Trustee with
     reference to Employees or Participants; and

           (c)  The written consent of the Board to the adoption of this Plan.
     Any adoption may be made retroactive to the beginning of a Plan Year by
     complying with the foregoing conditions on or before the last day of that
     Plan Year.

     10.2. No Joint Venture Implied:  The adoption instrument executed by an
           ------------------------
Employer shall become, as to it and its Employees, a part of the Plan.  However,
except as otherwise provided under the Plan, neither the adoption of the Plan by
an Employer, nor any act performed by it in relation to the Plan shall ever
create a joint venture or partnership relation between it and any other
Employer.  Although the Accounts of Participants employed by an Employers which
adopt the Plan shall be commingled for purposes of investment thereof, unless
the Committee and the Trustee are otherwise directed by the Board, amounts held
in the Trust Fund allocable to a particular Employer shall, on an ongoing basis,
be available to pay benefits to Participants employed by that Employer, and to
pay benefits to Participants employed by any other Employer which is an
Affiliated Employer required to be aggregated with the first such Employer, but
not otherwise.  In addition, unless the Committee and Trustee are otherwise
directed by the Board, the Committee shall maintain completely separate accounts
and records for the Plan Sponsor and each other Employer which is an Affiliated
Employer required to be aggregated with the Plan Sponsor (and Employees thereof
who are Participants), but otherwise the Plan shall be maintained on a
consolidated basis for the Plan Sponsor and all such other Affiliated Employers.
The Committee shall maintain completely separate accounts and records for any
Employer that is not an Affiliated Employer, as distinguished from maintaining
the Plan on a consolidated basis with such other Employer.

     10.3. Transfer of Participants:  If an Employee of one Employer is
           ------------------------
Transferred to the service of another Employer, the Employee shall maintain all
of his rights under the Plan.

                                      X-1
<PAGE>

Contributions to the Transferred Employee's Employer Account shall be handled in
accordance with the provisions of Sections 4.2 and 4.8, and his Active Service
shall be considered uninterrupted, as if no Transfer had occurred. Unless
otherwise provided hereunder, Active Service with any Employer or Affiliated
Employer shall count as Active Service with all Employers, whether before or
after the date that an Employer adopts the Plan.

                           AMENDMENT AND TERMINATION

     11.1. Right to Amend and Limitations Thereon:  The Board shall have the
           --------------------------------------
sole right to amend the Plan.  Any amendment shall (i) be made by a written
instrument and executed by an appropriate officer of the Plan Sponsor, (ii) set
forth the nature of the amendment and its effective date (which may be
retroactive), and (iii) be supported by a certified copy of the resolution or
direction which authorized or ratified it.  Although the Trustee shall be
expected to execute each amendment of the Plan, failure of the Trustee to
execute any such amendment shall not adversely affect the Plan Sponsor's
exclusive right to effectively amend the Plan without regard to any act or
forbearance on the part of the Trustee.  No amendment shall:

           (a)  Except as otherwise specifically provided in the Plan, cause or
     permit any Trust Fund assets to be diverted to any purpose other than the
     exclusive benefit of the Participants and their Beneficiaries;

           (b)  Decrease the accrued benefit of any Participant, or after July
     30, 1984, eliminate a protected form of benefit in violation of Section
     411(d)(6) of the Code;

           (c)  Increase the duties or liabilities of the Trustee without its
     prior written consent; or

           (d)  Change the vesting schedule to one which would result in the
     nonforfeitable percentage of the accrued benefit derived from Employer
     Contributions (determined as of the later of the amendment's adoption date
     or effective date) of any Participant being less than such nonforfeitable
     percentage computed under the Plan without regard to such amendment. If the
     Plan's vesting schedule is amended, or if the Plan is amended in any way
     that directly or indirectly affects the computation of the Participant's
     nonforfeitable percentage, or if the Plan is deemed amended by an automatic
     change to or from a Top-Heavy vesting schedule, each Participant with at
     least three years of service with an Employer may elect, within a
     reasonable period after the adoption of the amendment or change, to have
     the nonforfeitable percentage computed under the Plan without regard to
     such amendment or change. With respect to Participants who are not entitled
     to be credited with at least one hour of service in any Plan Year beginning
     after December 31, 1988, the immediately preceding sentence shall be
     applied by substituting "five years of service" for "three years of
     service". The period during which the election may be made shall begin no
     later than the date upon which the amendment is adopted or deemed to be
     made and shall end no later than the latest of the following dates: (1) the
     date which is sixty (60) days after the day that the amendment is adopted
     or deemed to be made; (2) the date which is sixty (60) days after the day
     that the amendment becomes effective; or (3) the date which is sixty (60)
     days after the day the Participant is issued written notice of the
     amendment by an Employer.

                                     XI-1
<PAGE>

     In the event of an amendment, each Employer will be deemed to have
consented to and adopted the amendment unless an Employer notifies the Plan
Sponsor, the Committee, and the Trustee to the contrary in writing within thirty
(30) days after receipt of a copy of the amendment, in which case the rejection
will constitute a withdrawal from the Plan by that Employer.

     11.2. Mandatory Amendments:  Except as otherwise provided in the Plan, or
           --------------------
except as otherwise prescribed by applicable law or other authority prescribed
thereunder by the appropriate governmental authority, the Contributions of each
Employer to the Plan are intended to be:

           (a) Deductible under applicable provisions of the Code;

           (b) Exempt from the federal Social Security Act, as amended;

           (c) Exempt from withholding under the Code; and

           (d) Excludible from any Employee's regular rate of pay, as that term
     is defined under the Fair Labor Standards Act of 1938, as amended.

     The Plan Sponsor shall make such amendments to the Plan as may be necessary
to carry out this intention, and all such amendments may be made retroactively.

     11.3. Withdrawal of an Employer:  An Employer may withdraw from the Plan
           -------------------------
either by rejecting an amendment or by giving written notice of its intent to
withdraw to the Plan Sponsor, the Committee and the Trustee.  The Committee
shall then determine, within ninety (90) days following the receipt of the
rejection or notice, the portion of the Trust Fund that is attributable to the
Participants employed by the withdrawing Employer and shall forward a copy of
such determination to the Trustee.  Upon receipt of the determination, the
Trustee shall immediately segregate those assets attributable to the
Participants employed by the withdrawing Employer and shall transfer those
assets to the successor trustee when it receives a designation of such successor
from the withdrawing Employer.

     The withdrawal from the Plan will not terminate the Plan with respect to
the withdrawing Employer. Instead, the withdrawing Employer shall, as soon as
practical, either appoint a successor trustee or trustees and reaffirm the Plan
as a new and separate plan and trust intended to qualify under Sections 401(a)
and 501(a) of the Code, or establish another plan and trust intended to qualify
under Sections 401(a) and 501(a) of the Code.

     The determination of the Committee, in its sole discretion, of the portion
of the Trust Fund that is attributable to the Participants employed by the
withdrawing Employer shall be final and binding upon all persons or entities;
and, the Trustee's transfer of those assets to the designated successor trustee
shall relieve the Trustee of any further obligation, liability or duty to

                                     XI-2
<PAGE>

the withdrawing Employer, the Participants employed by that Employer and their
Beneficiaries, and the successor Trustee.

     11.4. Voluntary and Involuntary Termination:  Any Employer may terminate
           -------------------------------------
its participation in the Plan by executing and delivering to the Committee and
the Trustee a notice which specifies the date on which its participation in the
Plan shall terminate.  Likewise, participation of an Employer in the Plan will
automatically terminate upon the general assignment by that Employer of
substantially all of its assets to or for the benefit of its creditors, or the
liquidation or dissolution of that Employer without a successor (whether or not
as the result of a bankruptcy proceeding).

     Upon termination of participation in the Plan by any Employer without
provision for continuation of the portion thereof attributable to such Employer,
subject to the provisions of this Section, the Trustee shall distribute to each
Participant employed by the terminating Employer the vested amounts certified by
the Committee as then credited to the Accounts of the Participants employed by
the terminating Employer.  If a Participant's vested Account balance (derived
from Employer and any Employee Contributions) which is distributable hereunder
does not exceed $3,500 (or for Plan Years beginning on and after January 1,
1998, $5,000), such Account balance shall be distributed in the form of a lump
sum payment which may be paid in cash or in kind (other than an annuity based on
the life of the Participant or any Beneficiary).  Such distribution may be made
without the necessity of obtaining the consent of the Participant.  If a
Participant's vested Account balance (derived from Employer and any Employee
Contributions) which is distributable hereunder is in excess of $3,500 (or for
Plan Years beginning on and after January 1, 1998, $5,000), and if the
Participant consents to the distribution hereunder in the form of a lump sum
payment, the Committee shall direct the Trustee to make settlement of a
Participant's Account as provided in the second preceding sentence.  If a
Participant's vested Account balance (derived from Employer and any Employee
Contributions) which is distributable hereunder is in excess of $3,500 (or for
Plan Years beginning on and after January 1, 1998, $5,000), and if the
Participant fails to consent to the distribution hereunder, the Committee shall
direct the Trustee to make settlement of the Participant's Account by
distribution of a deferred commercial annuity which can be purchased (with the
net proceeds of the Participant's vested Account balance) from any life
insurance company licensed to conduct business in the State of the situs of the
Trust, provided that such annuity (i) shall provide the same settlement
provisions as are set out in Article VI and (ii) shall be issued or endorsed as
nontransferable so that the owner thereof cannot sell, assign, discount, or
pledge as collateral for a loan or as security for the performance of an
obligation or for any other purpose his interest in such contract to any person,
other than the issuer of such annuity upon the surrender thereof, and, further
provided, that in the event of any conflict between applicable provisions of the
Plan (regarding the timing or manner of payment of benefit) and the terms and
provisions of any such commercial annuity purchased hereunder, the terms and
provisions of the Plan shall control.  Subject to subsequent provisions hereof,
distributions hereunder shall be made as soon as administratively practicable,
but in no event later than the time required under applicable provisions of the
Code.

                                     XI-3
<PAGE>

     In the event that (i) the Plan is maintained by the Plan Sponsor and at
least one other Employer which is an Affiliated Employer required to be
aggregated with the Plan Sponsor, (ii) on an ongoing basis, assets of the Plan
are available to pay benefits to any Employee who is a Participant (and
Beneficiaries thereof) and thus the Plan should be viewed as a single plan for
purposes of Section 414(1) of the Code, and (iii) the Plan is operated on a
consolidated basis, then, in that event, should any Employer which is an
Affiliated Employer terminate participation in the Plan without provision for
continuation of the portion thereof attributable to such Employer, subject to
application of Section 11.5 (relating to partial terminations), any forfeitures
arising incident to the distributions described above shall be allocated in
accordance with Section 4.6 ratably among the Plan Sponsor and each remaining
Employer which is an Affiliated Employer, to reduce future Contributions of each
such Employer. Any unapplied portion (comprised of excess amounts arising from
or attributable to Contributions of such terminating Affiliated Employer) of any
suspense account described in Section 4.3 shall be applied pro-rata to reduce
future Contributions of the Plan Sponsor and any remaining Employer which is an
Affiliated Employer.

     Regardless of whether the Plan is operated on an ongoing basis which should
result in the Plan being viewed as a single plan for purposes of Section 414(1)
of the Code, in the event that the Plan is not operated on a consolidated basis
and separate accounts and records are maintained for each separate Employer
under the Plan, then should any Employer which is an Affiliated Employer
terminate participation in the Plan without provision for continuation of the
portion thereof attributable to such Employer, Participants employed by such
terminating Employer as of the date of such termination of participation in the
Plan shall have a 100% vested and nonforfeitable interest in their Accounts.
Similar rules shall apply with respect to any other Employer with respect to
which the Plan is not operated on a consolidated basis.

     If the Plan should terminate, or should an Employer terminate its
participation in the Plan without causing the Plan to terminate, the Trustee, as
directed by the Committee, shall notify the Internal Revenue Service of such
termination of the Plan or termination of participation in the Plan by an
Employer, and the Plan Sponsor shall apply to the Internal Revenue Service for a
determination letter with respect to said termination of the Plan or termination
of participation in the Plan by an Employer. The Trustee shall not distribute
the assets in the Trust Fund in violation of applicable provisions of Article VI
of the Plan or prior to receipt of a copy of a determination letter from the
Internal Revenue Service to the effect that an immediate distribution of Plan
assets will not adversely affect the prior qualification of the Plan under
Sections 401(a) of the Code and the exemption of the Trust under Section 501(a)
of the Code. Provided further, notwithstanding any other provision of the Plan
to the contrary, amounts allocated and credited to the affected Participants'
Accounts may be distributed in any form authorized hereunder which constitutes a
lump sum distribution described in Section 401(k)(10) of the Code prior to such
time such amounts would otherwise be distributed if (i) the Plan is terminated
without establishment of a successor plan in contravention of Section
401(k)(10)(A)(i) of the Code and regulations or other authority issued
thereunder by the appropriate governmental authority, (ii) the Plan Sponsor or
other Employer effects a disposition (to an employer which is not an Affiliated
Employer) of substantially all of the assets (within the

                                     XI-4
<PAGE>

meaning of Section 409(d)(2) of the Code) used by such Plan Sponsor or other
Employer in a trade or business of such Plan Sponsor or other Employer with
respect to any former Participant who continues employment with the employer
which acquires such assets, and the Plan Sponsor or other Employer continues to
maintain the Plan after such disposition, or (iii) the Plan Sponsor or other
Employer effects a disposition (to an employer which is not an Affiliated
Employer) of its interest in a subsidiary (within the meaning of Section
409(d)(3) of the Code) with respect to any Participant who is a former Employee
of such Employer who continues employment with the subsidiary, and the Plan
Sponsor or other Employer continues to maintain the Plan after such disposition.
A distribution may be made under Section 401(k)(10) of the Code and clauses (ii)
and (iii) of this paragraph only if the Plan Sponsor or Employer continues to
maintain the Plan after the disposition. This requirement is satisfied only if
the purchaser does not maintain the Plan after the disposition. A purchaser
maintains the Plan if it adopts the Plan or otherwise becomes an employer whose
employees accrue benefits under the Plan. A purchaser also maintains the Plan if
the Plan is merged or consolidated with, or any assets or liabilities are
transferred from the Plan to, a plan maintained by the purchaser in a
transaction subject to Section 414(l)(1) of the Code. A purchaser is not treated
as maintaining the Plan merely because a plan that it maintains accepts rollover
contributions of amounts distributed by the Plan.

     For purposes of the previous paragraph, in accordance with Section 1.401
(k)-1(d)(3) of the Income Tax Regulations, a successor plan is any other defined
contribution plan maintained by the same employer. However, if fewer than two
percent (2%) of the employees who are eligible under the Plan at the time of its
termination are or were eligible under another defined contribution plan at any
time during the 24-month period beginning 12 months before the time of the
termination, the other plan is not a successor plan. The term "defined
contribution plan" means a plan that is a defined contribution plan as defined
in Section 414(i) of the Code, but does not include an employee stock ownership
plan as defined in Section 4975(e) or 409 of the Code or a simplified employee
pension as defined in Section 408(k) of the Code. A plan is a successor plan
only if it exists at the time the Plan is terminated or within the period ending
12 months after distribution of all assets from the Plan.

     Pursuant to Section 11.5, the termination of participation in the Plan by
any one or more of an Employers will not constitute a termination of the Plan
with respect to any other remaining Employers. Upon satisfaction of all
liabilities to all Participants and Beneficiaries hereunder, the Trust shall
terminate.

     11.5. Vesting Upon Discontinuance of Employer Contributions, Total or
           ---------------------------------------------------------------
Partial Termination:  Notwithstanding any other provision of the Plan, in the
- -------------------
event that there is a total or partial termination, or complete discontinuance
of an Employer Contributions hereunder, the vesting schedule contained in
Sections 6.4 shall be inapplicable to the affected Participants and each
affected Participant thereupon shall have a full 100% vested interest in the
amount credited to his Account as of the end of the last Plan Year for which a
substantial Employer Contribution was made and in any amounts thereafter
credited or allocated to his Account; provided, however, that if an Employer
shall thereafter resume making substantial Contributions hereunder, all amounts
credited or allocated to an affected Participant's Account with respect to the
Plan Year

                                     XI-5
<PAGE>

for which such Contributions are resumed, and the Plan Years for which they are
continued, shall vest only in accordance with the vesting schedules contained in
Sections 6.4. During any such period of termination or complete discontinuance
of Employer Contributions, all other provisions of the Plan shall nevertheless
continue in full force and effect, other than provisions for Employer
Contributions and the allocation thereof to the affected Participants' Accounts.
Except as otherwise provided in Section 11.4, the Plan shall not terminate
earlier than the effective date as of which the Plan is voluntarily terminated
by the Plan Sponsor or by the Plan Sponsor and the other Employers maintaining
the Plan.

     11.6. Continuance Permitted Upon Sale or Transfer of Assets:  An Employer's
           -----------------------------------------------------
participation in the Plan will not automatically terminate in the event that it
consolidates, merges, and is not the surviving corporation; sells substantially
all of its assets; is a party to a reorganization and its Employees and
substantially all of its assets are transferred to another entity; or liquidates
or dissolves, if there is a successor entity.  Instead, the resulting successor
person, firm, corporation, or other entity may assume and continue the Plan and
the Trust by executing a direction, entering into a contractual commitment or
adopting a resolution, as the case may be, providing for the continuance of the
Plan and the Trust simultaneous with or within one hundred twenty (120) days
after such consolidation, merger, sale, reorganization, liquidation or
dissolution.  If after such one hundred twenty (120) day period, the successor
entity has not assumed and continued the Plan and otherwise complied with the
provisions of Section 11.3, the successor entity shall be deemed to have given
notice under Section 11.4 and its participation in the Plan will then
automatically terminate on the one hundred twenty-first (121st) day and, in that
event, the appropriate portion of the Trust Fund will be distributed exclusively
to the affected Participants or their Beneficiaries as soon as practicable
pursuant to Section 11.4.

     11.7. Requirement on Merger, Transfer, etc:  Notwithstanding any other
           ------------------------------------
provision hereof, in accordance with Section 414(1) of the Code and regulations
or other authority issued thereunder by the appropriate governmental authority,
the Plan will not be merged or consolidated with, nor shall any assets or
liabilities of the Plan be transferred to, any other plan unless each
Participant would receive (if the Plan then terminated) a benefit immediately
after the merger, consolidation, or transfer which is equal to or greater than
the benefit that he would have been entitled to receive immediately before the
merger, consolidation, or transfer (if the Plan had then terminated).  In
addition, any accrued benefits under the Plan which are subject to and protected
under Section 411(d)(6) of the Code shall not be reduced or eliminated in
violation of Section 411(d)(6) of the Code (or regulations or other authority
issued thereunder by the appropriate governmental authority) incident to (i) any
merger, consolidation, spin-off or transfer of such accrued benefits or (ii) any
transaction involving an amendment or having the effect of an amendment of the
Plan to transfer such accrued benefits.

     Subject to Sections 8.2(i), 8.2(j), 8.2(k) and 9.2, the Trustee, as
directed by the Committee, shall have the authority to enter into (i) an
agreement to merge or consolidate the Plan with another plan which meets the
requirements of Sections 401(a) and 501(a) of the Code or (ii) an agreement to
accept the direct transfer of assets from any such plan or to transfer Plan
assets to any such plan. Except in cases in which the Plan accepts direct
rollovers of eligible

                                     XI-6
<PAGE>

rollover distributions in accordance with Section 401(a)(31) of the Code and
Section 6.6(c) hereof, to the extent that any such assets that are directly
transferred to the Plan are composed of amounts attributable to elective
contributions (described in Section 402(g)(3) of the Code), or qualified
nonelective contributions (described in Section 401(m)(4)(C) of the Code), or
match ing contributions (described in Section 401(m)(4)(A) of the Code) that are
treated as elective contributions under Section 401(k) of the Code, such amounts
shall remain subject to any limitations on distribution thereof and, thus, shall
not be distributed under the Plan prior to such time as is permitted under the
transferor plan and Section 401(k) of the Code. Subject to the Code Sections
described in the immediately preceding sentence, if assets are accepted on
behalf of any Employee prior to the date that such Employee is eligible to enter
the Plan as an active Participant, such Employee shall be deemed to be a
Participant; provided however, such Employee shall not be entitled to make or
authorize Contributions to the Plan or share in the allocation of any Employer
Contributions unless and until such Employee meets the requirements of Sections
2.1, 3.2 and 4.2 of the Plan.

     The Trustee shall not consent or be a party to a merger, consolidation or
transfer of assets with a defined benefit plan, except with respect to a
Rollover Contribution or a transfer which the Committee has determined to be an
"elective transfer" (described below). The Trustee shall hold, administer and
distribute the transferred assets as a part of the Trust Fund. Unless a transfer
of assets to the Plan is a Rollover Contribution or an "elective transfer"
(defined below), the Plan shall apply the optional forms of benefit protections
described in this Section and in Section 11.1 to all of the transferred assets.
A transfer is an elective transfer if: (i) the transfer satisfies the preceding
provisions of this Section; (ii) the transfer is voluntary, under a fully
informed election by the Participant; (iii) 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 and
the Participant's transferor plan account exceeds $3,500 (or for Plan Years
beginning on and after January 1, 1998, $5,000)); (iv) the transfer satisfies
the applicable spousal consent requirements of the Code; (v) the transferor plan
satisfies the qualified joint and survivor annuity notice requirements of the
Code, if the Participant's transferred benefit is subject to those requirements;
(vi) the Participant has the right to immediate distribution from the transferor
plan in lieu of the elective transfer; (vii) the transferred benefit is the
entire nonforfeitable accrued benefit under the transferor plan (1) calculated
to be at least the greater of the single sum distribution provided by the
transferor plan for which the Participant is eligible or the present value of
the Participant's accrued benefit under the transferor plan payable at that
plan's normal retirement age and (2) calculated by using an interest rate that
complies with the requirements of Section 417(e) of the Code and subject to the
overall limitations of Section 415 of the Code; (viii) the Participant has 100%
vested interest in the transferred benefit; and (ix) the transfer otherwise
satisfies applicable regulations or other guidance issued under applicable
provisions of the Code by the appropriate governmental authority.

                                  ARTICLE XII.

                                 MISCELLANEOUS

     12.1. Plan Not An Employment Contract:  The adoption and maintenance of the
           -------------------------------
Plan shall not be deemed to be a contract between any Employer and its Employees
which gives any Employee the right to be retained in the employment of any
Employer; to interfere with the rights of any Employer to discharge any Employee
at any time; or to interfere with any Employee's right to terminate his
employment at any time.

     12.2. Benefits Provided Solely From Trust Fund:  All benefits payable under
           ----------------------------------------
the Plan shall be paid or provided for solely from the Trust Fund; neither the
Committee nor any Employer assumes any liability or responsibility therefor.
Each Participant assumes all risks in connection with any decrease in the market
value of any common stocks or other investments held on his behalf in accordance
with the provisions of the Plan.

     12.3. Spendthrift Provision:  No principal or income payable, or to become
           ---------------------
payable, from the Trust Fund will be subject to:  (i) anticipation or assignment
by any Participant or by any Beneficiary; (ii) attachment by, interference with,
or control of any creditor of a Participant or Beneficiary; or (iii) being taken
or reached by any legal or equitable process in satisfaction of any debt or
liability of a Participant or Beneficiary prior to its actual receipt by such
Participant or Beneficiary.  Any attempted conveyance, transfer, assignment,
mortgage, pledge, hypothecate or encumbrance of the Trust Fund, or any part or
interest in it, by a Participant or Beneficiary prior to distribution will be
void, whether that conveyance, transfer, assignment, mortgage, pledge,
hypothecation or encumbrance is intended to take place or become effective
before or after any distribution of Trust Fund assets or the termination of the
Trust.  Furthermore, the Trustee shall not be required to recognize any
conveyance, transfer, assignment, mortgage, pledge, hypothecate or encumbrance
by a Participant or Beneficiary of the Trust, or any part or interest in it, or
to pay any money or thing of value to any creditor or assignee of a Participant
or Beneficiary for any cause whatsoever.

     This Section shall also apply to the creation, assignment, or recognition
of a right to any benefit payable with respect to a Participant pursuant to a
domestic relations order, unless such order is determined to be a qualified
domestic relations order (as defined in Section 414(p) of the Code). In
addition, in the event that, pursuant to a qualified domestic relations order
described above, an Account or subaccount is established for the benefit of the
former spouse or dependent of a Participant ("alternate payee"), and in the
further event that Participants are entitled to direct the investment of their
Accounts in accordance with Section 4.10, unless the Committee otherwise
prescribes pursuant to uniformly applied nondiscriminatory rules formulated by
the Committee, any alternate payee shall be considered to be a Participant for
purposes of Section 4.10 and, thus, shall be entitled to direct the investment
of such Account or subaccount.

     In the event that the Committee receives notice that a domestic relations
order that is intended to be qualified domestic relations order is being
prepared and will be provided to the Committee within a reasonably short time,
the Committee may place a temporary hold on the distribution of benefits under
the Plan to the affected Participant, pending (a) the determination

                                     XII-1
<PAGE>

of whether such order is a qualified domestic relations order within the meaning
of Section 414(p) of the Code, and (b) the rights of the alternate payee under
such order; provided that no such temporary hold shall prevent the Plan from
making any distributions required by Section 6.6(a)(iv) hereof.

     12.4. Gender, Tense and Headings:  Whenever the context so requires, words
           --------------------------
of the masculine gender used herein shall include the feminine and neuter, and
words used in the singular shall include the plural.  The words "herein,"
"hereof," "hereunder," and other similar compounds of the word "here" shall
refer to the entire Plan, not to any particular Section or provision of the
Plan.  Headings of Articles, Sections and subsections as used herein are
inserted solely for convenience and reference and constitute no part of the
Plan.

     12.5. General Transition Rules Relating to Amendment, Restatement and
           ---------------------------------------------------------------
Continuation of Plan:  This Section shall generally apply to any Prior Plan.
- --------------------

           (a)  Application of Plan:  Except as otherwise provided under the
                -------------------
     Plan, in the event that an Employer adopts the Plan as an amendment,
     restatement and continuation of a Prior Plan, the provisions of the Plan
     shall apply only to Employees whose employment with an Employer terminates
     after the effective date of the Plan. If an Employee's employment with an
     Employer terminates prior to the effective date of an Employer's adoption
     of the Plan, the former Employee shall be entitled to benefits under the
     terms and provisions of Employer's Prior Plan as that plan existed on the
     date of the termination of employment.

           (b)  Maintenance of Accounts:  Amounts credited to a Participant's
                -----------------------
     accounts under the Prior Plan as in effect immediately prior to the
     effective date of its amendment, restatement and continuation hereunder
     shall constitute the opening balances of corresponding Accounts established
     under the Plan. To the extent that individual direction of investment of
     individual Accounts is no longer permitted under the Plan after the
     effective date of an Employer's adoption thereof, the Committee may direct
     that such Accounts shall be liquidated and the proceeds shall establish
     opening Account balances as of the date specified by the Committee,
     whereupon such Accounts shall become part of the commingled Trust Fund
     subject to otherwise applicable rules for allocating income, gain, loss,
     appreciation or depreciation to Accounts.

           (c)  Employee Elections:  Employee elections (under the Prior Plan as
