      Section  4.1   Normal Retirement Benefits of Corporate Officers.  Subject
to the limitations elsewhere contained in this Plan, an Executive
Officer who incurs a Termination of Employment on or after attaining his Normal
Retirement Age and who was the President or a corporate Vice President of the
Company either (x) on the Effective Date or (y) as of the most recent date on
which he performed service as an Executive Officer shall be entitled to a

Compensation (as defined in Section 2.1(a)), over

            (b)   The monthly amount of the Participant's Accrued Benefit under
the Retirement Plan which would then be payable in the form of a Straight-Life
Annuity;

      provided, however, that (1) the normal retirement benefit payable in the
      form of a single life annuity under this Plan, as so calculated, of any
      Participant who was a participant in the Mosinee Supplemental Retirement
      Plan on the Effective Date shall be increased by an amount equal to such
      Participant's Accrued Benefit under the Wausau Paper Corp. Retirement
      Plan as of the Effective Date which would then be payable monthly in the
      form of a single life annuity and (2) the normal retirement benefit
      payable in the form of a single life annuity under this Plan, as so
      calculated, of any Participant who was eligible for and elected to
      receive the increased benefits provided under either Section 4.23 of the
      Mosinee Retirement Plan ("Section 4.23") or Section 3.20 of the Wausau

      Benefit under the Retirement Plan, determined in accordance with the
      increased benefits provided for in Section 4.23 or Section 3.20, as
      applicable, which would then be payable monthly in the form of a
      Straight-Life Annuity over (B) the amount of the Participant's Accrued
      Benefit under the Retirement Plan, determined without regard to the
      increased benefits provided for in Section 4.23 or Section 3.20, as
      applicable, which would then be payable monthly in the form of a
      Straight-Life Annuity.

      Section  4.2   Normal Benefits of Other Executive Officers.  Subject to
the limitations elsewhere contained in this Plan, an Executive
Officer who incurs a Termination of Employment on or after attaining his Normal

Retirement Age and who was not the President or a corporate Vice President of

on which he performed service as an Executive Officer, shall be entitled to a
retirement benefit under this Plan payable in the form of a single life annuity
determined in accordance with the formula set forth in Section 4.1; provided,

      Section  4.3   Minimum Retirement Benefits of Executive Officers.
Notwithstanding anything herein to the contrary, the normal retirement
benefit determined under Section 4.1 or 4.2, as applicable, shall not be less

Plan or b) Section 4.1 or 4.2, as applicable, under the Wausau Paper Mills
Company Executive Officers' Deferred Compensation Retirement Plan, determined

to the limitations elsewhere contained in this Plan, an Executive
Officer who incurs a Termination of Employment on or after attaining his Early
Retirement Age, but prior to attaining his Normal Retirement Age, shall be
entitled to an early retirement benefit in the form of a single life annuity
equal to the amount to which he would have been entitled to under Section 4.1
or Section 4.2, as applicable, taking into consideration the provisions of
Section 4.3, if applicable, if he had then attained his Normal Retirement Age;
provided, however, that such benefit shall be reduced by .4166% for each full
calendar month, from and including the month in which the Participant's 55th
birthday occurs to the month in which his 62nd birthday occurs, by which the
calendar month in which payment of the early retirement benefit provided for in
this Section 4.4 precedes the date on which such Participant would have
attained his Normal Retirement Age.

      Section  4.5   Surviving Spouse Benefits.  Subject to the limitations
elsewhere contained in this Plan, the Surviving Spouse of a Participant who
dies prior to commencement of any other benefit hereunder, including the
Surviving Spouse of a former Participant who terminated employment because of
Disability, shall be eligible for a Surviving Spouse benefit commencing as of
the last to occur of (1) the first day of the first month following the month
in which the Participant's death occurs or (2) the date on which the
Participant would have been eligible to receive payment of a benefit under
Section 4.4, or in the case of a Participant who incurred a Termination of
Employment because of Disability, commencing as of the date on which the former
Participant would have attained age 55, and such Surviving Spouse benefit shall
be equal to 50% of the monthly benefit which would have been payable to the
deceased Participant under this Plan if he had retired the day before his death
and payment of his benefit had commenced on such date assuming, in the case of
a former Participant who incurred a Termination of Employment because of a
Disability, that the benefit payable to such former Participant at Normal
Retirement Age under Section 4.1 or 4.2, as applicable, would have been
payable in reduced form at age 55 pursuant to Section 4.4, and, assuming
further, that in the case of a Participant or former Participant who died prior
to attaining age 55 or prior to the date on which the Participant or former
Participant had completed 10 years of Continuous Service, that a benefit would
have been payable to such deceased Participant or former Participant as of the
later of the dates described in (1) and (2), above; provided, however,

that the benefit payable to the Surviving Spouse of a Participant or former
Participant who died prior to the completion of 5 years of Continuous Service
shall be reduced by 20% for each year of Continuous Service less than 5 accrued
by such deceased Participant or former Participant.
                                       -7-
      Section  4.6   Commencement and Duration of Payments.  Monthly benefit
payments to the Participant (and, if applicable, his Surviving Spouse) under
Section 4.1, 4.2, 4.4 or 4.5, shall commence on the first date which is both
(i) the first day of a month, and (ii) if the Participant was a Key Employee on
the date of his Termination of Employment, not less than six months subsequent
to the date of his Termination of Employment or, if applicable, the date
specified in Section 4.5 as the date on which the Participant's Surviving
Spouse became eligible for a Surviving Spouse benefit, and shall continue,
subject to the provisions of Section 4.8, until the month in which the death
of the Participant (or, if applicable, his Surviving Spouse) occurs.

      Section  4.7   Change of Control.

            (a)   In the event a Change of Control of the Company occurs, the
Company shall pay to each Participant a lump sum amount equal to the present
value of the Participant's accrued normal retirement benefit, as determined
under Section 4.1, as of the first day following such Change of Control of the
Company and following the Participant's Termination of Employment which is both
(i) the first day of a month, and (ii) if the Participant was a Key Employee on
the date of his Termination of Employment, not less than six months subsequent
to the date of the Participant's Termination of Employment, whether or not such
Change of Control of the Company occurred prior to the date of the
Participant's Termination of Employment.  Upon payment of the lump sum amount
provided for in this Section 4.7(a), the Company shall have no further
obligation to pay any benefits under this Plan.  Notwithstanding the foregoing,
if a Participant has less than five years of Continuous Service as of the date
of the Change of Control, the amount paid to such Participant under this
Section 4.7(a) shall equal (i) the amount described in the first sentence of
this Section 4.7(a) times (ii) a fraction, the numerator of which is the number
of years and fractions thereof of the Participant's Continuous Service as of
the date of the Change of Control and the denominator of which is five.

            (b)   In the event a Change of Control of the Company occurs after
the Participant's death and whether or not a benefit shall have then become
payable to the Participant's Surviving Spouse, the Company shall pay to such
Participant's Surviving Spouse, if then living, the present value of the unpaid
Surviving Spouse benefit.  Upon payment of the lump sum amount provided for in
this Section 4.7(b), the Company shall have no further obligation to pay any
benefits under this Plan.  Notwithstanding the foregoing, if a Participant had
less than five years of Continuous Service as of the date of his or her death
before the Change of Control, the amount paid to such Participant Surviving
Spouse under this Section 4.7(b) shall equal (i) the amount described in the
first sentence of this Section 4.7(a) times (ii) a fraction, the numerator of
which is the number of years and fractions thereof of the Participant's
Continuous Service as of the date of death and the denominator of which is
five.
                                       -8-
            (c)   For purposes of this Plan, a "Change of Control of the
Company" shall mean:

                  (1)   The acquisition by any individual, entity or group
(within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange

the meaning of Rule 13d-3 promulgated under the Exchange Act) of 20% or more of
either (A) the then outstanding shares of common stock of the Company (the
"Outstanding Company Common Stock") or (B) the combined voting power of the
then outstanding voting securities of the Company entitled to vote generally in
the election of directors (the "Outstanding Company Voting Securities");
excluding, however, the following: (i) any acquisition directly from the

any employee benefit plan (or related trust) sponsored or maintained by the
Company or any entity controlled by the Company, (iv) any acquisition pursuant

acquisition by any of the Woodson Entities or any of the Smith Entities, or
(vi) any increase in the proportionate number of shares of Outstanding Company
Common Stock or Outstanding Company Voting Securities beneficially owned by a
Person to 20% or more of the shares of either of such classes of stock if such
increase was solely the result of the acquisition of Outstanding Company Common
Stock or Outstanding Company Voting Securities by the Company; provided,
however, that this clause (vi) shall not apply to any acquisition of
Outstanding Company Common Stock or Outstanding Company Voting Securities not
described in clauses (i), (ii), (iii), (iv), or (v) of this paragraph (1) by
the Person acquiring such shares which occurs after such Person had become the
beneficial owner of 20% or more of either the Outstanding Company Common Stock
or Outstanding Company Voting Securities by reason of share purchases by the
Company; or

                  (2)   A change in the composition of the Board of Directors

Board") cease for any reason to constitute at least a majority of the Board;
provided, however, for purposes of the Plan, that any individual who becomes a
member of the Board subsequent to the Effective Date whose election, or
nomination for election by the Company's shareholders, was approved by a vote
of at least a majority of those individuals who are members of the Board and
who were also members of the Incumbent Board (or deemed to be such pursuant to
this proviso) shall be deemed to be and shall be considered as though such
individual were a member of the Incumbent Board, but provided, further, that
any such individual whose initial assumption of office occurs as a result of
either an actual or threatened election
                                       -9-

assets of the Company or the acquisition of the assets or securities of any
other entity (a "Corporate Transaction"); excluding, however, such a Corporate

Company Common Stock and Outstanding Company Voting Securities immediately
prior to such Corporate Transaction will beneficially own, directly or

indirectly, more than 60% of, respectively, the outstanding shares of common
stock and the combined voting power of the then outstanding voting securities
entitled to vote generally in the election of directors, as the case may be, of
the corporation resulting from such Corporate Transaction (including, without
limitation, a corporation which as a result of such transaction owns the
Company or all or substantially all of the Company's assets either directly or

any Woodson Entity, any Smith Entity, or such Resulting Corporation) will

outstanding shares of common stock of the Resulting Corporation or the combined
voting power of the then outstanding voting securities of such Resulting
Corporation entitled to vote generally in the election of directors except to
the extent that such ownership existed with respect to the Company prior to the
Corporate Transaction, and (C) individuals who were members of the Incumbent
Board will constitute at least a majority of the members of the board of
directors of the Resulting Corporation; or

                  (4)   The Woodson Entities acquire beneficial ownership of

Corporation; or

                  (5)   The Smith Entities acquire beneficial ownership of more
than 35% of the Outstanding Company Common Stock or Outstanding Company Voting

            For purposes of this Section 4.7(b), the terms "Affiliate" and
            "Associate" shall have the meanings ascribed to such terms in Rule
            12b-2 of the General Rules and Regulations under the Exchange Act
            as in effect on the date of this Plan.

            (d)   For purposes of this Plan, the present value of a
Participant's retirement benefit or the Surviving Spouse benefit shall be
determined by reference to the 1983 Individual Annuity Mortality Table with an
assumed interest rate equal to the "immediate annuity rate" as then in effect
as determined by the Pension Benefit Guaranty
                                       -11-
Corporation and promulgated in Appendix B to 29 C.F.R. (section) 2619.65 or any
successor regulation adopted for the same or substantially similar purpose.

      Section  4.8   Forfeiture of Benefits.  Despite any other provision of
this Plan, a Participant's or Surviving Spouse's, as applicable, eligibility
for benefit payments under the Plan is expressly subject to the following terms
and conditions:

            (a)   The Company is and shall be entitled to the sole benefit and
exclusive ownership of any inventions or improvements in plant, machinery and
processes, and all patents for the same, and all customer or price lists, trade
secrets and other things of similar type or nature used in the business of the
Company that may be made or discovered by a Participant while he is employed by
the Company, or, after his Termination of Employment if arising out of his
activities, knowledge or experience gained while in the employment of the
Company.  In the event that a Participant, during or after his Termination of
Employment, discloses all or any portion of the list of the Company's customers
or the Company's pricing structure or all or any portion of the Company's
manufacturing process or any other trade secrets or confidential information to
any person, firm, corporation, associations or other entity for any reason or
purpose whatsoever, no payment of any benefit otherwise due the Participant or
his Surviving Spouse pursuant to this Plan shall be made by the Company.

            (b)   In the event a Participant, without the prior written consent
of the Company and  within a period of two years beginning on the first day
following the Participant's Termination of Employment, directly or indirectly
owns, manages, operates, joins, controls, is employed by or participates in the

ownership, management, operation or control of, or is connected in any manner
with, any business of a type and character which, in the opinion of the
Company, results in the Participant then being engaged in the field of
activities in which he was engaged by the Company at the time of his
Termination of Employment (and within one year prior to said termination) and
such business is, in the opinion of the Company, in direct or indirect
competition in any market area served by the Company with any business then
conducted by the Company in such market area, no payment of any benefit
otherwise due the Participant or his Surviving Spouse pursuant to this Plan
shall be made by the Company if the Participant fails to cease such activity
within fifteen days of the mailing to him by the Company of the Company's
opinion that he is in violation of the restrictions contained in this
Section 4.8(b).

            (c)   The Company shall have sole discretion to stop payment of any
benefit or refuse to make payments otherwise due the Participant or his
Surviving Spouse pursuant to this Plan if the Participant's Termination of
Employment or his appointment to a position with the Company as other than an
Executive Officer was by reason of or because of the Participant's fraud,
embezzlement, misappropriation or similar offense against the Company or any
other state or federal felony offense.
                                       -12-
            (d)   Subject to the provisions of Section 6.2, no benefit shall be
payable under this Plan to any Participant or Surviving Spouse who, for any
reason, is not eligible for and does not receive a benefit under the provisions
of the Retirement Plan.

      Section  4.9   Inalienability of Benefits.  A Participant's right to a
benefit under the Plan shall not be subject to voluntary or involuntary sale,
pledge, hypothecation, transfer or assignment by the Participant or by his
personal representatives or heirs, or any other person or persons or
organization or organizations succeeding to any of the Participant's rights
and benefits hereunder.

      Section  4.10  Facility of Payments.  Any benefit payable hereunder to
any person who is legally incapacitated may be paid to a court appointed legal
representative of such person.

      Section  4.11  Section 409A Compliance.  Notwithstanding any other
provision of the Plan or any election made or permitted to be made hereunder,
no election as to the timing or form, or both, of the distribution of a
Participant's accrued benefit, and no other distribution otherwise provided for
by this Plan, shall be effective or made, as the case may be, if such timing or
form of distribution would cause the Plan to fail to meet the requirements of
Code Section 409A or cause a Participant to be subject to the interest and
additional tax imposed pursuant to Code Section 409A(a)(1)(B), and any such
election or such other provision shall be modified in the operation of the Plan
so that the timing or form of distribution, or both, as the case may be,
corresponds as closely as possible to such election or other provision, but
will then comply with the requirements of Code Section 409A so as to preclude
the application of Code Section 409A(a)(1)(B).

      Section  4.12  Claims Procedure.  Each Participant or Surviving Spouse
whose claim for benefits is denied, in whole or in part, shall be provided with
a notice, written in a manner calculated to be understood by such person,
setting forth the specific reasons for such denial and outlining the review
procedure of the Company.  Each such Participant or Surviving Spouse shall be
given a reasonable opportunity for a full and fair review by the Company of the
decision by which the claim was denied.
                                       -13-

                      ARTICLE 5 -  PROVISION FOR BENEFITS


      Section  5.1   Assets of the Company.  Benefits which become payable
under the provisions of the Plan shall be paid directly by the Company out of
its assets.  No assets of the Company shall be set aside or segregated for the
provision of such benefit payments.  No Participant or Surviving Spouse, nor
any other potential or actual recipient of benefits under the provisions of
this Plan shall acquire any right, title or interest in the assets of the
Company by reason of the Plan and, to the extent that the Participant,
Surviving Spouse or such other recipient shall acquire a right to receive
payments from the Company pursuant to the Plan, such right shall be no greater
than the right of any unsecured general creditor of the Company.
                                       -14-
              ARTICLE 6 -  AMENDMENT AND TERMINATION OF THE PLAN


      Section  6.1   Amendment.  The Company reserves the right to amend the
Plan from time to time and at any time, effective as of any specified current,
prior or future date; provided, however, that no such amendment shall modify or
reduce a Participant's accrued benefit under this Plan as of the date such
amendment is adopted.

      Section  6.2   Termination.  The Company reserves the right to terminate
the Plan at any time and for any reason; provided, however, that upon
termination, each Participant's accrued benefit shall be fully vested subject
only to the provisions of Section 4.8.  A Participant's accrued benefit shall
mean the benefit which would be paid or payable pursuant to this Plan following
the Participant's Termination of Employment if the Retirement Plan had
terminated as of the same date on which the termination of the Plan occurs
(and provided for payment of Accrued Benefits under the Retirement Plan upon
the Participant's Termination of Employment) multiplied by a fraction, the
numerator of which is a Participant's years of Continuous Service recognized
under Section 3.2 and the denominator of which is ten.  Distributions upon
termination of the Plan will be made at such time as permitted under Code
Section 409A and the regulations promulgated thereunder.
                                       -15-

                          ARTICLE 7 -  MISCELLANEOUS


      Section  7.1   Nonguarantee of Employment.  Nothing contained in this
Plan shall be construed as a contract of employment between the Company and any
employee, as a right of any employee to be continued in the employment of the
Company as an Executive Officer or in any other capacity, or as a limitation of
the right of the Company to discharge any of its employees, with or without
cause.

and assigns.
