                       SENA 401(k) PLAN FOR UNION MEMBERS
                       ----------------------------------


                                    SECTION 1

                                  Introduction


1.1      Purpose

                  SENA 401(k) Plan for Union Members (the "plan") is maintained
by Stora Enso North America Corp. ("SENA") for eligible employees of SENA and
those United States subsidiaries of SENA which adopt the plan and trust with
SENA's consent. Prior to August 31, 2000, the plan was maintained by
Consolidated Papers, Inc. ("Consolidated") and was named the Consolidated
Employees Tax-Saver Investment Plan II (the "prior plan"). The prior plan was
amended and renamed the SENA 401(k) Plan for Union Members effective as of
November 15, 2000. The plan is intended to meet the requirements of a qualified
profit sharing plan under Sections 401(a) and 401(k) of the Internal Revenue
Code of 1986, as amended (the "Code"). The purpose of the plan is to permit
eligible employees of SENA and adopting subsidiaries of SENA to defer receipt of
current compensation under the qualified cash or deferred arrangement which
forms part of the plan and to share investment experience of such contributions,
thereby assisting eligible employees in providing for future financial security.



1.2      Effective Date, Plan Year

                  The original plan was established May 1, 1995. The "effective
date" of the amendment and restatement of the plan as set forth herein is
January 1, 2001. A "plan year" means SENA's taxable year for federal income tax
purposes, which taxable year is the calendar year.


1.3      Employers

                  SENA and any United States subsidiary of SENA which adopts the
plan and trust with the consent of SENA are sometimes referred to hereinafter
collectively as the "employers" and individually as an "employer." Wisconsin
River Power Company shall be considered an employer for purposes of the plan
through March 31, 2001. Subsequent to March 31, 2001, Wisconsin River Power
Company shall no longer be a participating employer in this plan.


1.4      Plan Administration

                  The plan will be administered by the SENA 401(k) Board (the
"Board") consisting of four members appointed by SENA, as described in Section
8.


1.5      Trustee, Trust Agreement, Trust Fund

                  Funds contributed by the employers under the plan will be held
and invested in a trust fund, until distributed, by a trustee (the "trustee")
appointed by SENA. The trustee will act under a trust agreement between the
employers and the trustee. Participants will be notified of the identity of the
trustee, and of any change in trustee.


1.6      Examination of Plan Documents

                  Copies of the plan and trust agreement, and any amendments
thereto, will be made available at the principal office of each employer where
they may be examined by any participant or beneficiary entitled to receive
benefits under the plan. The provisions of and benefits under the plan are
subject to the terms and provisions of the trust agreement.


1.7      Notices

                  Any notice or document required to be given to or filed with
the Board shall be considered as given or filed if delivered or mailed by
registered mail, postage prepaid, addressed as follows:

                  SENA 401(k) Board
                  c/o Stora Enso North America Corp.
                  510 High Street.
                  P.O. Box 8050
                  Wisconsin Rapids, WI 54495-8050


1.8      Gender and Number

                  Words in the masculine gender shall include the feminine and
neuter genders and, where the context admits, the plural shall include the
singular, and the singular shall include the plural.


1.9      Plan Supplements

                  The provisions of the plan may be modified by supplements to
the plan. The terms and provisions of each supplement are a part of the plan and
supersede the provisions of the plan to the extent necessary to eliminate
inconsistencies between the plan and the supplement.

1.10     Benefits for Participants Terminating Prior to January 1, 2001

                  Except as otherwise specifically provided under this plan, the
benefits of a participant who retired or otherwise terminated employment with
the employers prior to January 1, 2001 will be determined in accordance with the
terms of the plan as in effect on the date of such participant's retirement or
termination of employment and shall not be affected by any subsequent amendment
to the plan or the trust unless such amendment specifically provides that such
participant's benefits are to be affected thereby.

                                    SECTION 2

                          Eligibility and Participation


2.1      Eligibility

                  Subject to the limitations and conditions of the plan, each
employee of an employer who was an active participant in the plan immediately
prior to January 1, 2001 will continue as a participant on and after that date.
Each other active full-time employee (as defined below) will be eligible to
become a participant in the plan on his date of hire if he belongs to a
collective bargaining unit of employees represented by a collective bargaining
representative and there is an agreement between the employer and such
representative to extend this plan to such collective bargaining unit employees.
Each other employee (part-time employee) will be eligible to become a
participant in the plan on the first day following completion of a year of
service if he belongs to a collective bargaining unit of employees represented
by a collective bargaining representative and there is an agreement between the
employer and such representative to extend this plan to such collective
bargaining unit employees.

                  A "full-time employee" is an employee who at the time of his
employment is employed as a full-time employee and is expected to complete a
year of service as defined in subsection 2.2 commencing on the date of his
employment.

                  Each employee will be notified of the date as of which he
becomes a participant and will be furnished with a summary plan description in
accordance with governmental rules and regulations. Each participant will become
eligible to make income deferral contributions in accordance with subsection
2.6.


2.2      Year of Service

                  A "year of service" means each 12-consecutive month period
commencing on the date an employee is first employed by an employer, and on each
anniversary date thereof, during which he completes 1,000 hours of service (as
defined below), subject to the following:

                  (a)      A leave of absence (as defined below) will not
                           interrupt continuity of employment for purposes of
                           the plan but not more than 501 hours of service will
                           be credited to an employee for any one continuous
                           period of leave of absence.

                  (b)      A period of concurrent employment with two or more
                           employers will be considered as employment with one
                           employer during that period and an employee's
                           employment with any predecessor to an employer will
                           be considered as employment with that employer.

                  (c)      The termination of any employee's employment with one
                           employer will not interrupt the continuity of his
                           employment or participation if, concurrently with or
                           immediately after such termination, he is employed by
                           one or more other employers.

                  (d)      If a former employee of the employers is re-employed
                           by an employer before he has incurred a one-year
                           break in service (as defined in subparagraph (f)
                           below) his employment with the employers shall not be
                           deemed to have terminated.

                  (e)      A period of employment with a controlled group member
                           (as defined below) which is not an employer will be
                           considered a period of employment with an employer
                           for purposes of determining years of service. A
                           "controlled group member" means any corporation or
                           other trade or business which is under common control
                           with an employer within the meaning of Sections
                           414(b) and 414(c) of the Code.

                  (f)      If a former employee of the employers who has not
                           satisfied the requirements of subsection 2.1 is
                           re-employed by an employer after he has incurred a
                           one-year break in service, his prior period of
                           employment and years of service with the employers
                           prior to such one-year break in service shall be
                           disregarded for all purposes of the plan upon his
                           re-employment and such employee shall be treated as a
                           new employee for all purposes of the plan. A
                           "one-year break in service" will be deemed to have
                           occurred for each 12-month period (which 12-month
                           period shall be the same period for which a year of
                           service is computed) ending on or after the date of
                           an employee's termination of employment during which
                           he has completed less than 501 hours of service.

                  (g)      In the case of a maternity or paternity absence (as
                           defined below) an employee shall be credited, for the
                           first 12-month period (which 12-month period shall be
                           the same period for which breaks in service are
                           computed as described in subparagraph (f) above) in
                           which he otherwise would have incurred a one-year
                           break in service (and solely for purposes of
                           determining whether such a break in service has
                           occurred), with the hours of service which normally
                           would have been credited to him but for such absence
                           (or, if the Board is unable to determine the hours
                           which would have been so credited, 8 hours for each
                           workday of such absence). A "maternity or paternity
                           absence" means an employee's absence from work
                           because of the pregnancy of the employee or birth of
                           a child of the employee, the placement of a child
                           with the employee in connection with the adoption of
                           such child by the employee, or for purposes of caring
                           for the child immediately following such birth or
                           placement. The Board may require the employee to
                           furnish such information as the Board considers
                           necessary to establish that the employee's absence
                           was for one of the reasons specified above.

An "hour of service" means each hour for which an employee is directly or
indirectly paid, or entitled to payment, by an employer for the performance of
duties and for reasons other than the performance of duties, including each hour
for which back pay, irrespective of mitigation of damages, has been either
awarded or agreed to by an employer, determined and credited in accordance with
Department of Labor Reg. Sec. 2530.200b-2.


2.3      Leave of Absence

                  A leave of absence will not interrupt continuity of service or
participation in the plan. A "leave of absence" for plan purposes means a leave
of absence required by law or granted by an employer on account of service in
military or governmental branches described in any applicable statute granting
re-employment rights to employees who entered such branches, or any other
military or governmental branch designated by the employers, and also means any
other absence from active employment with an employer under conditions which are
not treated by an employer as a termination of employment including, but not
limited to, vacations, holidays, maternity, illness, incapacity, or jury duty.
Leaves of absence will be governed by rules uniformly applied to all employees
similarly situated. Notwithstanding any provision of the 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.


2.4      Re-employed Former Participant

                  If a former participant in the plan is re-employed by an
employer after incurring a one-year break in service, he will become a
participant in the plan on the date he meets the requirements of subsection
2.1and will be eligible to make income deferral contributions under subsection
2.6 on the date he becomes a participant.


2.5      Restricted Participation

                  In the event a participant in the plan is transferred to
employment with a group of employees to which the plan has not been extended or
is then eligible to participate in the SENA 401(k) Plan or the SENA 401(k) Plan
for Kimberly Union Members, he shall be treated as a participant for all
purposes of the plan except that the participant shall not be entitled to defer
additional amounts under the plan as provided in subsection 2.6 after the date
of such transfer. If such a participant subsequently again satisfies the
requirements of subsection 2.1 of the plan, he will become an active participant
in the plan on the date he meets the requirements of subsection 2.1 and will be
eligible to make income deferral contributions under subsection 2.6 on the date
he becomes a participant.


2.6      Election to Defer Compensation

                  Subject to the limitations of subsection 3.2, a participant,
if he so desires, may defer payment of a percentage (in increments of one-half
percent) of his compensation ("income deferral contributions"):

                  o        not exceeding 15 percent thereof for SENA members of
                           the Paper, Allied, Industrial, Chemical and Energy
                           Workers International Union, Office and Professional
                           Employees International Union and Hotel Employees and
                           Restaurant Employees International Union, and

                  o        not exceeding 25 percent thereof or, if lesser, such
                           percentage specified in Section 415(c)(1)(B) of the
                           Code or the maximum percentage permitted for tax
                           deduction purposes by an employer under Section 404
                           of the Code, for Stora Enso North America Corp.
                           members,

                           (i)      effective February 14, 2000, of the

                  o        not exceeding 25 percent thereof or, if lesser, such
                           percentage specified in Section 415(c)(1)(B) of the
                           Code or the maximum percentage permitted for tax

                           members effective March 9, 2000 through March 31,
                           2001 of the IBEW,



by electing, in a manner prescribed by the Board, to have such percentage
withheld from his compensation and contributed to the plan on his behalf by his
employer

                  For the plan year beginning on January 1, 2001, no participant
may elect to make income deferral contributions for the plan year in excess of
$10,500. For plan years beginning on or after January 1, 2002, no participant
may elect to make income deferral contributions in excess of:

--------------------------------------------------------------------------------
     Income Deferral Contribution Limit             For Plan Years Beginning
--------------------------------------------------------------------------------
                  $11,000                                January 1, 2002
--------------------------------------------------------------------------------
                  $12,000                                January 1, 2003
--------------------------------------------------------------------------------
                  $13,000                                January 1, 2004
--------------------------------------------------------------------------------
                  $14,000                                January 1, 2005
--------------------------------------------------------------------------------
     $15,000 (or such greater amount as             January 1, 2006 or after
determined pursuant to Section 402(g)(4) of
                 the Code)
--------------------------------------------------------------------------------


                  The Board reserves the right to adjust the income deferral
contribution percentages of such participants as necessary in order to satisfy
the limitation requirements of such contributions under Section 415 of the Code.

                  The amounts withheld from a participant's compensation
pursuant to the participant's election shall be contributed to the plan by the
participant's employer and credited to his investment account(s) as provided in
subsection 4.5. A participant may elect to change the rate of his deferrals or
suspend or resume such deferrals, within the limits stated above, by making a
new election.

                  Each election under this subsection shall be made at such
time, in such manner and in accordance with such rules as the Board shall
determine and initially shall be effective for compensation paid on the first
payment date coincident with or next following the date for which such election
is effective.


2.7      Compensation and Adjusted Compensation

                  A participant's "compensation" for any plan year means the sum
total of the adjusted compensation (as defined below) paid to him during that
plan year for services rendered to the employers as an employee and the amount
of any income deferral contributions made for such year under Sections 125 or
401(k) of the Code. A participant's "adjusted compensation" for any plan year
means a participant's compensation to be reported on Internal Revenue Service
Form W-2 excluding any extraordinary compensation (including, but not limited
to, special project bonuses or incentives, non-cash items, disability payments,
safety shoe and clothing allowances, taxable group term life insurance, awards,
prizes, or any other unusual compensation) unless the Board shall determine that
such compensation shall be included. For the plan year beginning on January 1,
2001, no "compensation" in excess of $170,000 shall be taken into account for
purposes of the plan. For plan years beginning on or after January 1, 2002, no
"compensation" in excess of $200,000 (or such greater amount as permitted under
Section 401(a)(17) of the Code for such plan year) shall be taken into account
for purposes of the plan.

                                    SECTION 3

                       Income Deferral Contribution Rules


3.1      Income Deferral Contributions

                  Subject to the limitations of this Section 3, each participant
may elect to have contributed to the plan on his behalf, by making an election
pursuant to subsection 2.6, the amount such participant has directed to have
withheld from his compensation. Such contributions shall be paid to the trustee
and credited to the participant's investment account(s) in accordance with the
participant's investment election as provided in subsection 4.5, as soon as
practicable after being withheld but, in any event, not later than 15 business
days following the end of the month during which such amounts are withheld.


3.2      Limitations on Income Deferrals

                  In no event shall the actual deferral percentage (as defined
below) of highly compensated participants (as defined in subsection 3.3) for any
plan year exceed the greater of:

                  (a)      the actual deferral percentage of all other
                           participants for such plan year multiplied by 1.25;
                           or

                  (b)      the actual deferral percentage of all other
                           participants for such plan year multiplied by 2.0;
                           provided that the actual deferral percentage of the
                           highly compensated participants does not exceed that
                           of all other participants by more than 2 percentage
                           points.

The "actual deferral percentage" of a group of participants for a plan means the
average of the ratios (determined separately for each participant in such group)
of A to B where A equals the income deferral contributions credited to each such
participant's investment accounts (as described in subsection 4.1) for such plan
year, and B equals the participant's "compensation" for such plan year. For
purposes of this subsection, "compensation" means an employee's compensation (as
defined in Section 414(s) of the Code), including income deferral contributions
made for such year under Sections 125 and 401(k) of the Code. The Board shall
determine from time to time from the participant's current income deferral
elections whether the foregoing limitation will be satisfied and, to the extent
necessary to insure compliance with such limitation, shall reduce income
deferral contributions made by highly compensated participants (in the order of
their contribution amounts beginning with the largest amount) until such
limitation is satisfied. In addition, if at any time, because of the foregoing
limitations, a portion of the income deferrals withheld from a participant's
compensation cannot be credited to his investment accounts, the participant
shall be deemed not to have elected such income deferrals and the amount of such
income deferral contributions (and any income allocable to such contributions)
will be distributed to such highly compensated participant no later than two and
one-half months after the close of the plan year for which such excess
contribution was made. For purposes of determining the amount of any income for
a plan year attributable to any excess contributions by a highly compensated
participant (as defined in subsection 3.3) to be returned to such participant,
the following formula will be used:

                  (i)      First, the value of his account as of the beginning
                           of the plan year and as of the last day of the plan
                           year shall be determined.

                  (ii)     Next, the gain or loss on such account shall be
                           determined after first reducing the difference
                           between the balance of the account as at the end of
                           the year and the balance as at the beginning of the
                           year by income deferral contributions made for such
                           year.

                  (iii)    Next, the amount calculated under paragraph (ii)
                           shall be multiplied by a fraction the numerator of
                           which is the excess contributions made by the
                           participant for such year and the denominator of
                           which is such participant's account as of the last
                           day of such year, reduced by the amount of any gain
                           for such year and increased by the amount of any loss
                           for such year. Such amount shall be the amount of
                           income to be returned to the participant for such
                           year.

For purposes of this subsection, certain former employees (as determined under
Section 414(q)(9) of the Code) shall be treated as employees for purposes of
determining highly compensated participants.


3.3      Highly Compensated Participants

                  For purposes of subsection 3.2 of the plan, a "highly
compensated participant" means any participant who:

                  (a)      was a 5 percent owner of an employer or controlled
                           group member during the current or immediately
                           preceding plan year; or

                  (b)      received annual compensation from an employer or
                           controlled group member of more than $85,000 (or such
                           greater amount as may be determined by the
                           Commissioner of Internal Revenue) during the
                           immediately preceding plan year and was in the
                           top-paid 20% of the employees for such year.

For purposes of this subsection 3.3, "compensation" shall mean total cash
compensation determined in accordance with Section 415(c)(3) of the Code and
regulations thereunder, but including any elective deferral (as defined in
Section 402(g)(3) of the Code) and any amount contributed or deferred by an
employee of an employer or controlled group member under Section 125 or 457 of
the Code.


3.4      American Depositary Shares

                  Notwithstanding any other provision of the plan, effective
upon the merger of Consolidated Papers, Inc. and Stora Enso Oyj, "company stock"
shall mean American Depositary Shares (ADSs) of Stora Enso Oyj in place of the
common stock of Consolidated Papers, Inc.


3.5      Verification of Contributions

                  A certificate of an independent certified public accountant
selected by SENA shall be conclusive on all persons as to the amount of
contributions under the plan for any plan year.


3.6      No Interest in Employers

                  The employers shall have no right, title, or interest in the
trust fund, nor will any part of the trust fund at any time revert or be repaid
to an employer, unless:

                  (a)      a contribution is made by such employer by mistake of
                           fact and such contribution is returned to the
                           employer within one year after payment to the
                           trustee, or

                  (b)      a contribution conditioned on the deductibility
                           thereof is disallowed as an expense for federal
                           income tax purposes and such contribution (to the
                           extent disallowed) is returned to the employer within
                           one year after payment to the trustee.

The amount of any contribution that may be returned to an employer pursuant to
subparagraph (a) or (b) above shall be reduced by any portion thereof previously
distributed from the trust fund and by any losses of the trust fund allocable
thereto and in no event may the return of such contribution cause any
participant's account balances to be less than the amount of such balances had
the contribution not been made under the plan.

                                 Plan Accounting


4.1      Accounts

                  A separate account will be maintained in the name of each
participant which will reflect the contributions made by his employer for his
benefit under subsection 3.1 and his interest in each of the investment funds,
if any, described in subsection 4.2. The Board may direct the maintenance of
such other accounts or subaccounts as it deems necessary or desirable for
purposes of plan administration. Unless the context indicates otherwise,
references in the plan to a "participant's accounts" means all accounts
maintained in his name under the plan.


4.2      The Trust Fund and Investment Funds

                  SENA maintains a trust agreement with a trustee under which
all assets of the plan are held. The trust agreement provides for the
administration of the trust fund. The establishment of individual accounts for
each participant shall not be construed to prevent the trustee from commingling
and maintaining the various participants' accounts as a single fund.

                  The trust shall consist of such "investment funds" as the
Board may from time to time establish, terminate or modify. Earnings and gains
or losses derived from the assets in any investment fund shall be reflected in
the balance of such investment fund under the plan.

                  The trustee shall invest the trust fund in proportion to the
aggregate of investment elections made by participants under subsections 4.5 and
4.6, as adjusted in accordance with subsection 4.4 at such times during the plan
year as directed by the Board.


4.3      SEO Unitized Stock Fund

                  The SEO Unitized Stock Fund is a fund which invests in
American Depositary Shares (ADSs) of Stora Enso Oyj and short term investments.
It is not a mutual fund. A participant's account in the SEO Unitized Stock Fund
is measured in units.

                  Any cash dividends received by the trustee with respect to
ADSs of Stora Enso Oyj shall be applied by the trustee to purchase additional
ADSs or to pay cash distributions or transfers in accordance with the provisions
of the trust. Any ADSs received by the trustee as a stock split or stock
dividend or as a result of a reorganization or recapitalization shall be
allocated and credited to the accounts of participants in the SEO Unitized Stock
Fund, according to the units (including fractional units) previously credited to
such accounts.

                  Notwithstanding any other provision in the plan, effective
upon the merger of Consolidated Papers, Inc. and Stora Enso Oyj, the
Consolidated Papers, Inc. Common Stock Fund was replaced by the SEO Unitized
Stock Fund. Any ADSs of Stora Enso Oyj received by a participant as a result of
the merger between Consolidated Papers, Inc. and Stora Enso Oyj were allocated
and credited to the participant's account in the SEO Unitized Stock Fund.


4.4      Other Account Adjustments

                  At such times during the plan year as the Board may direct (an
"adjustment date"), but not less than once annually on each December 31, the
trustee shall value each investment fund and adjust each participant's account
balance to reflect the effect of income and contributions received, any changes
in fair market value, expenses, withdrawals, transfers, loans, distributions and
all other transactions since the preceding adjustment date respecting the
particular fund.


4.5      Investment Elections

                  Each participant, in accordance with rules established by the
Board, may elect the respective percentages of his income deferral contributions
to be allocated to and invested in each of the investment funds. An election,
once made, shall continue in effect until such election is changed or revoked by
subsequent election. If no election has been made by a participant, 100 percent
of his income deferral contributions will be invested in the Money Market Fund.


4.6      Transfers Between Investment Funds

                  Subject to any restrictions on the transfer from or to a
particular investment fund which may be established by the Board, each
participant may elect to transfer amounts credited to his account under one
investment fund to his account under any other investment fund. Such transfers
(the number and frequency of which shall be established from time to time by the
Board) will occur as of any adjustment date or as soon as practicable thereafter
provided that the participant makes his transfer election according to
procedures established by the Board for this purpose.


4.7      Statement of Accounts

                  The Board shall direct the trustee to furnish each participant
with a statement reflecting the balances in his investment accounts as at such
dates as may be designated by the Board after all adjustments required under the
plan have been made, with at least one annual statement each plan year ending
December 31.


4.8      Rollovers

                  In accordance with such rules as the Board may establish from
time to time:

                  (i)      rollover amounts described in Section 402(c) of the
                           Code,

                  (ii)     rollover contributions described in Section 408(d)(3)
                           of the Code, and

                  (iii)    benefits of an employee under any other plan
                           qualified under Section 401(a) of the Code which can
                           be transferred pursuant to Section 401(a)(31) of the
                           Code may be transferred in cash to and held by the
                           trustee and will be credited to an account
                           established in the name of the employee,

                  (iv)     excluding any after tax amounts,

may be rolled over to this plan. Any amount received by the trustee for an
employee in accordance with the foregoing will be subject to all applicable
accounting provisions of Section 4 until distributed in accordance with
subsection 5.3 of the plan. Such balance, as adjusted under the plan, will be
fully vested and nonforfeitable.


4.9      Authority of Board to Modify Accounting Procedures

                  Notwithstanding any other provisions of this Section 4, the
Board has directed the maintenance of a system of daily or on-demand
recordkeeping under the plan and the trust. Notwithstanding any provision of the
plan to the contrary, the Board may provide for participant elections under
subsection 2.6, adjustment of participants' accounts under subsection 4.4,
participants' investment elections under subsection 4.5 and participant
transfers between investment funds under subsection 4.6 as frequently as it
deems appropriate and may make any accounting adjustments in subsection 4.4 as
it deems necessary to accommodate such system of daily or on-demand
recordkeeping system. The Board, in its discretion, may establish such written
procedures as it deems necessary to implement this subsection.

                                    SECTION 5

            Nonforfeitable Rights, Voting of Shares and Distributions


5.1      Nonforfeitable Rights

                  Subject to the provisions of subsection 3.6, each
participant's accounts, as adjusted under the terms of the plan, shall at all
times be fully vested and nonforfeitable.


5.2      Voting of American Depositary Shares

                   The trustee shall furnish, to each participant who has ADSs
credited to his investment account under the SEO Unitized Stock Fund, notice of
the date of each meeting of the shareholders of Stora Enso Oyj at which ADSs are
entitled to be voted. Such notice shall include all information provided other
shareholders with respect to the exercise of voting rights and request from each
participant instructions as to the voting (or the exercise of any rights other
than voting rights) at that meeting of ADSs credited to his account under the
SEO Unitized Stock Fund. If the participant furnishes such instructions to the
trustee within the time specified in the notification given to him, the trustee
shall vote such ADSs (or exercise any other rights other than voting rights) in
accordance with the participant's instructions (as allowed under the laws of
Finland and the United States). Unless otherwise required by law, the trustee
shall vote the ADSs pursuant to the majority of the directions received in order
to comply with Finnish law. Except as otherwise required by law or Finnish
securities regulations, the trustee shall not vote ADSs reflecting a
participant's proportional interest in the SEO Unitized Stock Fund for which it
has received no direction from the participant.


5.3      Distribution Upon Termination

                  If a participant's employment with all of the employers is
terminated on account of retirement or for any other reason, distribution of his
accounts shall be made to him or, in the event of his death, to his beneficiary
(as defined in subsection 5.4) as soon as practicable after the first adjustment
date coincident with or next following the date on which his employment
terminates after all adjustments required under the plan as of that adjustment
date have been made in accordance with Section 4. Notwithstanding the foregoing,
and except as provided below in this subsection, payment of a participant's
benefits will be made (or installment payments will commence) not later than 60
days after the latest of (a) the end of the plan year in which a participant
attains normal retirement age, (b) the end of the plan year in which the
participant terminates his employment with an employer, or (c) such later date
on which the amount of the payment can be ascertained by the Board.

                  Distribution of a participant's account shall be made at the
direction of the participant (or, in the event of the participant's death, the
participant's beneficiary), in one lump sum, in a series of quarterly or annual
installments of substantially equal amounts over a reasonable period of time, as
directed by the participant, not exceeding the lesser of 10 years or the joint
life expectancy of the participant and his beneficiary, or transferred to an
eligible retirement plan in accordance with the provisions of subsection 5.8. If
the value of a participant's accounts at the date of distribution exceeds
$5,000, such participant's benefits will be distributed to the participant prior
to age 70 1/2 only with the participant's written consent.

                  If a participant dies after payment of his benefits has begun
but has not been completed, the remaining portion of such benefits shall be
distributed over a period not exceeding the period over which payments were
being made to the participant. If a participant dies before payment of his
benefits has begun, his benefits must be distributed over a period not exceeding
the greatest of:

                  (i)      five years from the death of the participant;

                  (ii)     in the case of payments to a designated beneficiary
                           other than the participant's spouse, the life
                           expectancy of such beneficiary, provided payments
                           begin within one year of the participant's death; or

                  (iii)    in the case of payments to the participant's spouse,
                           the life expectancy of such spouse, provided payments
                           begin by the date the participant would have attained
                           age 70 1/2,

                  A participant's SEO Unitized Stock Fund account shall be
distributed in the form of ADSs equal to the number of full ADSs credited to his
SEO Unitized Stock Fund account and cash representing the balance of any
fractional ADS and any short term investments in his account, with the fair
market value of any ADSs being determined as of the date of distribution to the
participant or, the participant or his beneficiary may elect to receive the
value of his SEO Unitized Stock Fund account in cash. Distribution of all other
amounts shall be made in cash.

                  A participant may elect to defer distribution of his account
balances, but not beyond his required commencement date. For purposes of this
subsection 5.3, a participant's "required commencement date" means April 1 of
the calendar year next following the later of the calendar year in which the
participant attains age 70 1/2 or the calendar year in which he terminates
employment with the employers; provided, however, that the required commencement
date of a participant who is a five percent owner (as defined in Section 416 of
the Code) with respect to the plan year ending in the calendar year in which he
attains age 70 1/2 shall be April 1 of the next following calendar year. Until
all of a participant's benefits have been distributed under the plan, all
appropriate accounting provisions of Section 4 shall apply to the participant's
accounts under the plan.

                  All distributions under the plan shall comply with Section
401(a)(9) of the Code. With respect to distributions under the plan made on or
after September 1, 2001 for calendar years beginning on or after January 1,
2001, the plan will apply the minimum distribution requirements of Section
401(a)(9) of the Code in accordance with the regulations under such Code section
that were proposed on January 17, 2001 (the 2001 Proposed Regulations),
notwithstanding any provision of the plan to the contrary. If the total amount
of required minimum distributions made to a participant for 2001 prior to
September 1, 2001 are less than the amount determined under the 2001 Proposed
Regulations, then the amount of required minimum distributions for 2001 on or
after such date will be determined so that the total amount of required minimum
distributions for 2001 is the amount determined under the 2001 Proposed
Regulations. This subsection shall continue in effect until the last calendar
year beginning before the effective date of the final regulations under Section
401(a)(9) of the Code or such other date as may be published by the Internal
Revenue Service.


5.4      Designation of Beneficiary

                  Each participant from time to time, by signing a beneficiary
designation form, may designate any natural or legal person or persons (who may
be designated concurrently, contingently, or successively) to whom his benefits
are to be paid if he dies before he receives any or all of his benefits;
provided, however, that the beneficiary of a participant who is married on the
date of his death shall be his surviving spouse, if any, unless the participant
has designated another person as his beneficiary and the participant's spouse
consents thereto in writing and such consent acknowledges the effect of the
designation and is witnessed by a company benefit representative or a notary
public. A beneficiary designation form and any spousal consent will be effective
only when filed with the Board or its designee while the participant is alive
and will cancel all beneficiary designation forms previously so filed. If a
deceased participant who was not married on the date of his death failed to
designate a beneficiary as provided above, or if the deceased participant's
spouse or other beneficiary designated by him dies before him or before complete
payment of the participant's benefits, the Board, in its sole discretion, may
direct that the participant's benefits be paid to:

                  (a)      The legal representative or representatives of the
                           estate of the last to die of the participant, his
                           spouse, and any natural person chosen as the
                           participant's designated beneficiary or, if the
                           estate has been closed, to

                  (b)      One or more of the participant's relatives by blood,
                           adoption, or marriage and in such proportions as the
                           Board determines.

The term "designated beneficiary" as used in the plan means the natural or legal
person or persons (including a trustee or other legal representative acting in a
fiduciary capacity) designated by a participant as his beneficiary in the last
effective beneficiary designation form filed with the Board under this
subsection. The term "beneficiary" as used in the plan means the natural or
legal person or persons to whom a deceased participant's benefits are payable
under this subsection.


5.5      Hardship Withdrawals

                  A participant may request to withdraw all or any portion of
the net credit balance in his investment accounts equal to his income deferral
contributions provided that the withdrawal is necessary because of a hardship,
as defined below, causing immediate and heavy financial needs on the
participant. Such request shall be made in accordance with procedures
established by the Board, and shall be effective in accordance with such rules
as the Board shall establish from time to time. The request must include the
participant's certification in writing that such withdrawal does not exceed the
amount required to meet such immediate financial need, including anticipated
taxes due to such withdrawal, and not is reasonably available from other
resources of the participant, including:

                  (i)      cessation of income deferral contributions to the
                           plan,

                  (ii)     a loan from the plan,

                  (iii)    the borrowing from commercial sources on reasonable
                           commercial terms,

                  (iv)     reimbursement or compensation by insurance or
                           otherwise, or

                  (v)      reasonable liquidation of the participant's assets.

                  A participant may not withdraw an amount greater than the
amount of his income deferral contributions (excluding gains or earnings on such
contributions) plus any amounts credited to his account under subsection 4.8 and
earnings thereon, if any. Such withdrawal shall not exceed the value of such
accounts as of the adjustment date coincident with or next preceding the date of
withdrawal.

                  Hardship means an immediate and heavy financial need of a
participant due to:

                  (i)      any extraordinary expenses incurred on account of
                           accident, sickness, disability, or other financial
                           emergency affecting him or any of his dependents
                           which are not reimbursable by insurance but qualify
                           under Section 213 of the Code as medical expenses for
                           tax deduction purposes for the participant without
                           regard for the percentage of income requirement, or

                  (ii)     tuition and related expenses for the next twelve
                           months of his post-secondary education or the
                           post-secondary education of his dependents, or

                  (iii)    payment on the purchase price of his principal
                           residence, payments of principal on a mortgage on
                           such residence (not including regular mortgage
                           payments), or payments for initial construction of a
                           principal residence to be occupied by the
                           participant, but shall not include any expenditures
                           for nonstructural capital items, or

                  (iv)     payments necessary to prevent foreclosure or eviction
                           from a primary residence (whether this is past due
                           mortgage or rent).

                  The Board, or its designee, shall determine under uniform and
nondiscriminatory standards, that the hardship request meets the criteria for a
hardship. The decision of the Board shall be binding on all participants.

                  Participants for whom a hardship withdrawal is processed shall
be prohibited from making income deferral contributions to this plan for twelve
months from the date on which such hardship withdrawal is processed for hardship
withdrawals taken prior to January 1, 2001. For hardship withdrawals taken on or
after January 1, 2002, a participant shall be prohibited from making income
deferral contributions to this plan for six months from the date on which such
hardship withdrawal is processed.

                  In addition, the limitation, (imposed by Section 402(g) of the
Internal Revenue Code, as adjusted for changes in the cost of living), on a
participant's income deferral contributions, pursuant to subsection 2.6 of this
plan, for a participant receiving a hardship withdrawal shall, for the
participant's next tax year, be reduced by the amount of such participant's
total income deferral contributions made to the plan in the participant's tax
year in which the participant's hardship withdrawal was processed.


5.6      Pre-Termination Distributions

                  A participant who has attained age 59 1/2 may irrevocably
elect that the entire net credit balance in his investment accounts (after any
adjustments required under the plan have been made) be distributed to him as
soon as practicable thereafter by payment in a lump sum. A distribution to a
participant under this subsection shall immediately be charged to such
participant's account but shall not prohibit the participant from continuing to
participate in the plan.


5.7      Loans to Participants

                  While it is the primary purpose of the plan to assist eligible
employees in providing for future financial security, the Board may offer a
participant loan program pursuant to such rules as the Board may from time to
time establish. Such program shall allow a participant limited access to a
portion of the participant's account through loans for specific purposes.

                  (a)      Eligibility. Participants whose account balances are
                           at least $2,000 may apply for a loan.

                  (b)      Purpose of Loan. Loans will be permitted for:

                           (i)      "hardship" cases described in subsection
                                    5.5, or

                           (ii)     purchase, refinancing, or renovation of the
                                    plan participant's principal or secondary
                                    residence, including the purchase of land to
                                    be used for building a principal or
                                    secondary residence, or

                           (ii)     expenses incurred in adoption of a child by
                                    the participant, including legal fees and
                                    agency fees.

                  (c)      Amount of Loan. The minimum principal amount of a
                           loan is $1,000.

                           The maximum total amount of all outstanding loans of
                           a participant is 50% of the participant's account
                           balance but not more than $50,000 (reduced by any
                           outstanding loan balance(s)).

                           The amount of any loan made to a participant from his
                           account will be charged against each of the
                           investment funds in the same percentage the
                           participant has elected to have his accounts invested
                           in each of such investment funds.

                  (d)      Interest Rate. Each loan shall bear a reasonable rate
                           of interest, determined as the prime rate published
                           in the Wall Street Journal on the first working day
                           of the month in which application for such loan is
                           made under rules promulgated by the Board.

                  (e)      Amortization Period. In general, loans shall be
                           amortized for repayment in equal payments not to
                           exceed 60 months. However, loans for the purpose of
                           purchasing a primary residence shall not be subject
                           to the 60-month repayment period but shall instead by
                           amortized over a period, not to exceed a maximum
                           period of 15 years.

                           In the event of a participant's leave of absence, a
                           loan may be reamortized during its term but the
                           repayment period of any refinanced loan shall not
                           exceed the original period of the loan. However, in
                           the event of a participant's military leave of
                           absence while a loan is outstanding, the original
                           period of the loan shall be extended by the length of
                           the military leave in accordance with Section
                           414(u)(4) of the Code.

                  (f)      Applying for a Loan. A participant may apply for a
                           loan by completing and signing a note and disclosure
                           agreement as provided by the trustee. The Board or
                           its designee shall review the loan application to
                           determine if the loan's purpose, amount, repayment
                           schedule and the participant's ability to repay the
                           loan meet the requirements of this subsection.

                  (g)      Repayment. Loan repayments shall be made at least
                           monthly, according to the schedule established in the
                           note and disclosure agreement. Payments shall be made
                           by payroll deduction by actively employed
                           participants.

                           Inactive participants must repay the loan in full no
                           later than six months following the month in which
                           the participant is no longer actively employed,
                           except that a loan for the purchase of the
                           participant's principal residence where the loan's
                           amortization period exceeds 60 months may be repaid
                           within the time prescribed in accordance with such
                           loan's original amortization period.

                           Repayment of principal and interest for a loan shall
                           be credited to the participant's account in the same
                           percentage as elected by the participant in
                           accordance with subsection 4.6 of the plan.

                           Advance repayment of the full loan amount, including
                           accumulated interest, shall be permitted.

                           Loan repayments will be suspended under the plan as
                           permitted under Section 414(u)(4) of the Code in the
                           case of a participant's military service.

                  (h)      Security. The loan shall be an investment of the
                           participant's account. Each loan shall be secured by
                           a pledge of an equal amount of the participant's
                           account balance under the plan.

                  (i)      Default. In the event a participant fails to repay a
                           loan within the time prescribed and according to its
                           tenor and the loan is declared in default by the
                           Board, any balance due and any interest accrued
                           thereon shall be treated as a deemed distribution in
                           accordance with regulations issued by the Internal
                           Revenue Service. In any event, if upon a
                           participant's termination of employment, any loan
                           made to him or any portion thereof, together with
                           accrued interest thereon, remains unpaid, the total
                           of the unpaid balance of such loans and accrued
                           interest thereon shall be deemed distributed to the
                           participant and charged against his account before
                           distribution of the participant's account balance is
                           made to the participant.

                           The Board shall take reasonable action with an active
                           participant to try to prevent a default. This
                           includes reamortization of the loan, including an
                           extension, provided such reamortization or extension
                           would not violate any limits set forth in subsection
                           (e) above. The Board shall, after all reasonable
                           actions have failed to bring the loan current and to
                           maintain such loan according to its tenor, declare
                           the loan in default.

                           Any defaulted loan of a participant, which has been
                           treated as a deemed distribution, including any
                           interest accumulated thereon, shall continue to be
                           taken into account in determining any new allowable
                           loan for the participant, until such defaulted loan
                           has been repaid to the plan.


5.8      Direct Transfer of Eligible Rollover Distributions

                  Notwithstanding any provision of the plan to the contrary, a
distributee may elect, at the time and in the manner prescribed by the Board, to
have any portion of an eligible rollover distribution paid directly to an
eligible retirement plan specified by the distributee in a direct rollover. An
"eligible rollover distribution" is any distribution of all or any portion of
the balance to the credit of the distributee, except that an eligible rollover
distribution shall not include:

                  (i)      any distribution that is one of a series of
                           substantially equal periodic payments (not less
                           frequently than annually) made for the life (or life
                           expectancy) of the distributee or the joint lives (or
                           joint life expectancies) of the distributee and the
                           distributee's designated beneficiary or for a
                           specified period of ten years or more;

                  (ii)     any distribution to the extent such distribution is
                           required under Section 401(a)(9) of the Code; and

                  (v)      any hardship withdrawals made under the 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 a surviving spouse,
an eligible retirement plan is an individual retirement account or individual
retirement annuity. For purposes of this subsection, a distributee includes an
employee or former employee. In addition, the employee's or former employee's
surviving spouse and the employee's or former employee's spouse or former spouse
who is the alternate payee under a qualified domestic relations order, as
defined in Section 414(p) of the Code are distributees with regard to the
interest of the spouse or former spouse. A direct rollover is a payment by the
plan to the eligible retirement plan specified by the distributee.


5.9      Distribution to Alternate Payees

                  Any domestic relations order issued by a State Court of
Jurisdiction, which assigns all or a portion of a participant's benefits under
the plan to an alternate payee shall be delivered to the Board or its designee.
The Board, or its designee, shall render an opinion as to whether the domestic
relations order is a "qualified domestic relations order" as defined by Section
414(p) of the Code.

                  The Board, or its designee, may direct the trustee to
distribute amounts payable under a qualified domestic relations order to the
alternate payee(s) under such order on the earliest date specified in such
order, without regard to whether such distribution is made or commences prior to
the participant's earliest retirement age (as defined in Section 414(p)(4)(B) of
the Code) or the earliest date that the participant could commence receiving
benefits under the plan.

                  In no event shall a domestic relations order cause the total
benefit, on behalf of a participant, the participant's beneficiaries and all
alternate payees, to exceed the participant's vested interest in the plan or
cause benefits to be payable in a form other than as available under the plan.
Likewise, benefits assigned to an alternate payee under a previous domestic
relations order may not be alienated under a subsequent domestic relations
order.

                                    SECTION 6

                          Limitations on Contributions


6.1      Contribution Limitations

                  For the plan year beginning January 1, 2001, the "annual
addition" (as defined below) to a participant's accounts under this plan shall
not exceed the lesser of:

                  (a)      $30,000; or

                  (b)      25 percent of the participant's compensation (as
                           determined under Section 415 of the Code) for such
                           plan year.

For each plan year commencing on or after January 1, 2002, the "annual addition"
(as defined below) to a participant's account under this plan shall not exceed
the lesser of:

                  (c)      $40,000 ((or such greater amount as may be determined
                           by the Commissioner of Internal Revenue); or

                  (d)      100 percent of the participant's compensation for
                           such plan year.

The term "annual addition" for any plan year means the sum of the following
amounts credited to a participant's accounts under such plan for that year:

                  (e)      employer contributions, including income deferral
                           contributions;

                  (f)      participants' contributions, if any; and

                  (g)      forfeitures.

                 The annual addition to a participant's accounts under this plan
will be reduced by the amount of annual additions credited to such participant's
accounts under any other defined contribution plan maintained by the employers
or controlled group members. If for any plan year the amount allocable to any
participant under the plan would exceed the maximum annual addition, such excess
amount shall be reduced by returning part, or (if necessary) all, of the income
deferral contributions credited to the participant's investment accounts during
the plan year. A participant's "compensation" for purposes of this subsection
6.1 means a participant's total cash compensation determined in accordance with
Section 415(c)(3) of the Code and regulations thereunder, but including any
elective deferral (as defined in Section 402(g)(3) of the Code) and any amount
contributed or deferred by an employer or controlled group member under Section
125 or 457 of the Code.

                                    SECTION 7

                               General Provisions


7.1      Interests Not Transferable

                  The interests of persons entitled to benefits under the plan
are not subject to their debts or other obligations and, except as may be
required by the tax withholding provisions of the Code or any state's income tax
act or pursuant to a qualified domestic relations order as defined in Section
414(p) of the Code, may not be voluntarily or involuntarily sold, transferred,
alienated, assigned, or encumbered.


7.2      Facility of Payment

                  When a participant or other person entitled to benefits under
the plan is under a legal disability or, in the Board's opinion, is in any way
incapacitated so as to be unable to manage his financial affairs, the Board may
direct that such participant's or person's benefits be distributed to his legal
representative or to a relative or friend of such person for his benefit, or the
Board may apply the benefits of such person in any manner that the Board may
select which is consistent with the plan and permitted by law.


7.3      Absence of Guaranty

                  The trustee, the Board, and the employers do not in any way
guarantee the trust fund from loss or depreciation. The employers do not
guarantee any payment to any person. The liability of the Board and the trustee
to make distribution under the plan is limited to the available assets of the
trust fund.


7.4      Employment Rights

                  The plan does not constitute a contract of employment or serve
to alter the at-will nature of employment, and participation in the plan will
not give any employee the right to be retained in the employ of the employers,
nor any right or claim to any benefit under the plan, unless such right or claim
has specifically accrued under the terms of the plan.


7.5      Litigation by Participants or Other Persons

                  No litigation may be begun against an employer, the Board (or
any member thereof) or the trustee or on behalf of any person with respect to
benefits under the plan until all administrative remedies under the plan,
including an appeal under subsection 7.8 have been exhausted.

                  To the extent permitted by law, if a legal action begun
against an employer, the Board (or any member thereof), or the trustee by or on
behalf of any person with respect to benefits under the plan results adversely
to that person, or if a legal action arises because of conflicting claims to a
participant's or beneficiary's benefits, the cost to any employer, the Board (or
any member thereof), or the trustee of defending the action will be charged to
the extent possible to the sums, if any, that were involved in the action or
were payable to the participant or beneficiary concerned.


7.6      Evidence

                  Evidence required of anyone under the plan may be by
certificate, affidavit, document or other information which the person acting on
it considers pertinent and reliable, and signed, made or presented by the proper
party or parties.


7.7      Action by Employers

                  Any action required or permitted of an employer under the plan
shall be by resolution of the Board of Directors of SENA or by a duly authorized
committee of the Board of Directors of SENA, or by a person or persons
authorized by resolution of the Board of Directors of SENA or such committee.


7.8      Review of Benefit Determinations

                  The Board, or its designee, will provide notice in writing to
any participant, beneficiary, or other person whose claim for benefits under the
plan is denied, wholly or partially, within a reasonable period of time, but not
later than 90 days after receipt of the claim.

                  Within 60 days of receipt by the participant, beneficiary or
other person of the written notice of denial of the claim, the participant may
file a written request with the Board for a full and fair review of the denial
of the participant's claim for benefits, including a hearing if deemed necessary
by the Board. In connection with the participant's appeal of the denial of
benefits, the participant may review pertinent documents and may submit issues
and comments in writing. The Board will deliver to the participant a written
decision on the claim no later than 60 days after the receipt of the
participant's request for review except that if there are special circumstances,
(such as a need to hold a hearing), which require an extension of time for
processing, the 60-day period will be extended to 120 days.


7.9      Waiver of Notice

                  Any notice required under the plan maybe waived by the person
entitled to notice.


7.10     Controlling Law

                  Except to the extent superseded by federal law, the laws of
State of Wisconsin shall be controlling in all matters relating to the plan.


7.11     Determination of Fair Market Value

                  The fair market value of ADSs of Stora Enso Oyj. on any
particular date shall be determined in accordance with the trust or under any
other method required under regulations adopted by the Internal Revenue Service.
In the event an employer contribution is made in ADSs, the value of such ADSs
shall be equal to the fair market value, as determined in good faith and in
accordance with regulations prescribed by the Internal Revenue Service.


7.12     Statutory References

                  Any reference in the plan to a section of the Code, the
Employee Retirement Income Security Act of 1974, or any other federal law, shall
include any comparable section or sections of any future legislation that
amends, supplements, or supersedes that section.


7.13     Severability

                  In the event any provision of the plan is held illegal or
invalid for any reason, such illegality or invalidity shall not affect the
remaining provisions of the plan, and the plan shall be construed and enforced
as if such illegal and invalid provision had never been incorporated in the
plan.


7.14     Fiduciary Responsibilities

                  Each fiduciary of the plan shall discharge his duties with
respect to the plan solely in the interest of plan participants and their
beneficiaries and with 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 like
character and with like aims.


7.15     Withholding

                  The trustee shall withhold for federal or state income tax
purposes from any distributions or withdrawals made under the plan such amounts
as are required under Internal Revenue Service regulations or under applicable
state law.


7.16     Leased Employees

                  A leased employee (as defined below) shall not be eligible to
participate in the plan. A "leased employee" means any person who is not an
employee of the employer, but who has provided services to the employer under
primary direction and control by the employer, on a substantially full time
basis for a period of at least one year, pursuant to an agreement between the
employer and a leasing organization. The period during which a leased employee
performs services for an employer shall be taken into account for purposes of
subsection 2.2 of the plan unless:

                  (i)      such leased employee is a participant in a money
                           purchase pension plan maintained by the leasing
                           organization which provides a nonintegrated employer
                           contribution rate of at least 10 percent (10%) of
                           compensation, immediate participation for all
                           employees and full and immediate vesting, and

                  (ii)     leased employees do not constitute more than 20
                           percent (20%) of the employer's nonhighly compensated
                           work force.

                                    SECTION 8

                                SENA 401(k) Board


8.1      Membership

                  A Board consisting of four members (who may but need not be
employees of an employer) shall be appointed by SENA. The Secretary of SENA
shall certify to the trustee from time to time the appointment to (and
termination of) office of each member of the Board and the person who is
selected as secretary of the Board.


8.2      Board's General Powers, Rights, and Duties

                  In addition to the powers, rights, and duties given to the
Board elsewhere in the plan and the trust documents, the Board shall control and
manage the operation and administration of the plan. The Board shall have the
discretionary and exclusive right to construe and interpret the plan and to
decide all matters arising thereunder. All determinations of the Board with
respect to any matter hereunder shall be conclusive and binding on all persons
subject to the appeal procedures provided in this plan. Without limiting the
generality of the foregoing, the Board shall have the following powers, rights,
and duties:

                  (a)      To select a secretary, if it believes it advisable,
                           who may but need not be a Board member.

                  (b)      To determine, in the Board's sole discretion, all
                           questions arising under the plan, including the power
                           to determine the rights or eligibility of employees
                           or participants and any other persons to benefit
                           under the plan, and the amount of their benefits
                           under the plan, and to remedy ambiguities,
                           inconsistencies, or omissions. Benefits under this
                           plan will only be paid if the Board decides in its
                           discretion that the applicant is entitled to them.

                  (c)      To adopt such rules of procedure and regulations as
                           in the Board's opinion may be necessary for the
                           proper and efficient administration of the plan and
                           as are consistent with the plan and trust agreement.

                  (d)      To enforce the plan in accordance with the terms of
                           the plan and the trust agreement and the rules and
                           regulations adopted by the Board.

                  (e)      To direct the trustee as respects payments or
                           distributions from the trust fund in accordance with
                           the provisions of the plan.

                  (f)      To furnish the employers with such information as may
                           be required by them for tax or other purposes in
                           connection with the plan.

                  (g)      To employed agents, attorneys, accountants or other
                           persons (who also may be employed by the employers)
                           and to allocate or delegate to them such powers,
                           rights, and duties as the Board may consider
                           necessary or advisable to properly carry out
                           administration of the plan.

                  (h)      To delegate to employees of SENA or the trustee, who
                           are not Board members, such duties and functions
                           relating to the plan, including but not limited to,
                           administration of participant accounts, claims,
                           requests for loans, withdrawals, changes to
                           investments and income deferral contributions, as the
                           Board determines appropriate. The Board and the
                           trustee retain full and exclusive authority over and
                           responsibility for any such duties or activities
                           delegated to and performed by employees of SENA or
                           the trustee and nothing contained in this subsection
                           shall be construed to confer upon any such employee
                           any discretion, authority or control respecting the
                           management, administration and operation of the plan.


8.3      Manner of Action

                  During a period in which two or more Board members are acting,
the following provisions apply where the context admits:

                  (a)      A Board member by writing may delegate any or all of
                           his rights, powers, duties, and discretions to any
                           other member, with the consent of the latter.

                  (b)      The Board members may act by meeting or by writing
                           signed without meeting, and may sign any document by
                           signing one document or concurrent documents.

                  (c)      An action or decision of a majority of the members of
                           the Board as to a matter shall be as effective as if
                           taken or made by all members of the Board.

                  (d)      If, because of the number qualified to act, there is
                           an even division of opinion among the Board members
                           as to a matter, a disinterested party selected by the
                           Board shall decide the matter and his decision shall
                           control.

                  (e)      Except as otherwise provided by law, no member of the
                           Board shall be liable or responsible for an act or
                           omission of the other Board members in which the
                           former has not concurred.

                  (f)      The certificate of the secretary of the Board or of a
                           majority of the Board members that the Board has
                           taken or authorized any action shall be conclusive in
                           favor of any person relying on the certificate.


8.4      Interested Board Member

                  If a member of a Board also is a participant in the plan, he
may not decide or determine any matter or question concerning distributions of
any kind to be made to him or the nature or mode of settlement of his benefits
unless such decision or determination could be made by him under the plan if he
were not serving on the Board.


8.5      Resignation or Removal of Board Members

                  Any member of the Board may be removed by SENA at any time,
with or without cause, by giving 10 days' prior written notice to him and the
other members of the Board. A member of the Board may resign at any time by
giving 10 days' prior written notice to SENA and the other members of the Board.
SENA may fill any vacancy in the membership of the Board, provided, however,
that if a vacancy reduces the membership of the Board to less than three, such
vacancy shall be filled as soon as practicable. SENA shall give prompt notice
thereof to the other members of the appropriate Board. Until any such vacancy is
filled, the remaining members may exercise all of the powers, rights, and duties
conferred on the Board.


8.6      Information Required by Board

                  Each person entitled to benefits under the plan shall furnish
the Board with such documents, evidence, data, or information as the Board
considers necessary or desirable for the purpose of administering the plan. The
employers shall furnish the Board with such data and information as the Board
may deem necessary or desirable in order to administer the plan. All information
furnished to the Board shall be maintained in confidence by Board members. The
records of the employers as to an employee's or participant's period of
employment, hours of service, termination of employment and reason therefor,
leave of absence, reemployment, and compensation will be conclusive on all
persons unless determined to the Board's satisfaction to be incorrect.


8.7      Uniform Rules

                  The Board shall administer the plan on a reasonable and
nondiscriminatory basis and shall apply uniform rules to all persons similarly
situated.


8.8      Board's Decision Final

                  Subject to applicable law, any interpretation of the
provisions of the plan and any decisions on any matter within the discretion of
the Board made by the Board in good faith shall be binding on all persons. A
misstatement or other mistake of fact shall be corrected when it becomes known
and the Board shall make such adjustment on account thereof as it considers
equitable and practicable.

                     Amendment, Termination and Plan Merger


9.1      Amendment

                  While SENA and the employers expect and intend to continue the
plan, SENA reserves the right to amend the plan from time to time and to the
extent that SENA may deem advisable without the consent of any other employer,
trustee, participant or beneficiary. Such amendment shall be in writing and duly
signed by an authorized officer of SENA and presented to the Board

                  No amendment to the plan shall decrease a participant's
accrued benefit determined immediately prior to the later of the date the
amendment is adopted or effective, shall have the effect of vesting in an
employer any interest in or control over any asset held hereunder by the
trustee, result in the return or repayment of any part of the trust fund to any
employer (subject to subsection 3.6) or distribution of the trust fund to anyone
other than participants and any other person entitled to benefits under the plan
or shall increase the duties or responsibilities of the trustee or the Board
without the respective written consent of the trustee or the Board.


9.2      Termination

                  Subject to the provisions for the next sentence, SENA may
terminate the plan at any time by giving advance written notice of the
termination to the Board, the trustee and other employers. If the plan is
terminated as to all participants (or if there is a partial termination of the
plan as respects some participants), the accounting provisions of the plan shall
continue to apply to the extent appropriate so that distribution of
participants' benefits may be made to them after their termination of employment
with the employers in accordance with subsection 5.3.


9.3      Plan Merger or Consolidation

                  In no event shall there by any merger or consolidation of this
plan with, or transfer of assets or liabilities of this plan to, any other plan
unless each participant in this plan would (if the other plan were then
terminated) receive a benefit immediately after the merger, consolidation, or
transfer which is equal to or greater than the benefit the participant would
have been entitled to receive immediately before the merger, consolidation, or
transfer (if this plan had then been terminated).


9.4      Notice of Amendment, Termination or Plan Merger

                  Participants affected thereby will be notified of an
amendment, termination, plan merger or consolidation within a reasonable time.

                      Special Rules When Plan is Top-Heavy


                  A-1. Purpose and Effect. The purpose of this Supplement A is
to comply with the requirements of Section 416 of the Code. The provisions of
this Supplement A shall apply for each plan year in which the plan is a
"top-heavy plan" within the meaning of Section 416(g) of the Code.

                  A-2. Top-Heavy Plan. In general, the plan will be a top-heavy
plan for any plan year, if, as of the last day of the preceding (current plan
year for the first plan year) plan year (the "determination date"), the sum of
amounts in (a),(b), and (c) below for key employees (as defined below and in
Section 415(i)(1) of the Code) exceeds 60 percent of the sum of such amounts for
all employees who are covered by a defined contribution plan or defined benefit
plan which is aggregated in accordance with paragraph A-4 below:

                  (a)      The aggregate account balances of participants under
                           this plan.

                  (b)      The aggregate account balances of participants under
                           any other defined contribution plan included in
                           paragraph A-4.

                  (c)      The present value of cumulative accrued benefits of
                           participants under any defined benefit plan included
                           in paragraph A-4.

In making the foregoing determination:

                           (i)      a participant's account balances shall be
                                    increased by the aggregate distributions, if
                                    any, made with respect to the participant
                                    during the five-year period ending on the
                                    determination date,

                           (ii)     the account balances of a participant who
                                    was previously a key employee, but who is no
                                    longer a key employee, shall be disregarded,

                           (iii)    the accounts of a beneficiary of a
                                    participant shall be considered accounts of
                                    the participant, and

                           (iv)     the account balances of a participant who
                                    has not performed services for an employer
                                    during the five-year period ending on the
                                    determination date shall be disregarded.

                  A-3. Key Employee. In general, a "key employee" is an employee
who, at any time during the five-year period ending on the determination date,
is or was:

                  (a)      an officer of an employer or controlled group member
                           receiving annual compensation greater than 50 percent
                           of the limitation in effect under Section
                           415(b)(1)(A) of the Code; provided that for purposes
                           of this subparagraph (a), no more than 50 employees
                           of the employer and the controlled group members (or
                           if lesser, the greater of 3 employees or 10 percent
                           of the employees) shall be treated as officers;

                  (b)      one of the ten participants receiving annual
                           compensation of more than the limitation in effect
                           under Section 415(c)(1)(A) of the Code and owning the
                           largest interests in an employer in excess of a 0.5
                           percent interest;

                  (c)      a 5 percent owner of an employer; or

                  (d)      a 1 percent owner of an employer receiving annual
                           compensation from the employers and all other
                           controlled group members of more than $150,000.

For purposes of this Supplement A, the term "compensation" shall mean
compensation within the meaning of Section 1.415-2(d) of the Code.

                  A-4. Aggregation of Plans. Each other defined contribution
plan and defined benefit plan maintained by the employers or controlled group
members which covers a "key employee" as a participant or which is maintained by
the employers or controlled group members in order for a plan covering a "key
employee" to be qualified shall be aggregated in determining whether this plan
is top-heavy.

                  A-5. Minimum Employer Contribution. For any plan year in which
the plan is a top-heavy plan, the employer contribution credited to each
participant who is not a key employee shall not be less than 3 percent of such
participant's compensation for that year. In no event, however, shall the
employer contribution credited in any year to a participant who is not a key
employee (expressed as a percentage of such participant's compensation) exceed
the maximum employer contribution credited in that year to a key employee
(expressed as a percentage of such key employee's compensation up to the
limitation in Section 401(a) (17) of the Code). Income deferral contributions
made under subsection 3.1 shall not be treated as an employer contribution.

                  A-6. Maximum Compensation. For any plan year in which the plan
is a top-heavy plan, a participant's compensation in excess of the limitations
in Section 401(a)(17) of the Code (or such greater amount as may be determined
by the Internal Revenue Service for that plan year) shall be disregarded for
purposes of determining an employer's contribution made under subsection 3.1 of
the plan.

                  A-7. No Duplication of Benefits. If the employer and
controlled group members maintain more than one plan, the minimum contribution
otherwise required under paragraph A-5 above may be reduced in accordance with
regulations of the Secretary of the Treasury to prevent inappropriate
duplication of minimum benefits or contributions.

                  A-8. Deleted.

                  A-9. Use of Terms. All terms and provisions of the plan shall
apply to this Supplement A, except that where the terms and provisions of the
plan and this Supplement A conflict, the terms and provisions of this Supplement
A shall govern.
