Dear Shareholder:

      You are cordially invited to attend our annual meeting of shareholders to
be held on April 22, 2004, at The Wausau Club, Wausau, Wisconsin.

      At the annual meeting you will be asked to elect two Class II directors.
The Board has nominated Dennis J. Kuester for reelection and Andrew N. Baur as
a new director to fill the remaining Class II director vacancy.  You will also
be asked to approve the 2000 Stock Incentive Plan which has been amended to
permit the use of restricted stock as part of the Company's incentive
compensation program.

      Richard L. Radt and Harry R. Baker have attained the mandatory retirement
age for directors and will retire at the annual meeting.  Mr. Radt retires as
Vice Chairman of the Company after service as President and CEO of the Company
from 1977 to 1987 and of Mosinee Paper from 1988 to 1993.  Mr. Baker has served
as director since 1992 and has been Chairman of the Audit Committee since April
2001.  I'm sure you will join me in thanking them for their many years of
service to the Company.

      Details on the time and place of the meeting are set forth in the
attached notice and proxy statement as are information on matters to be voted
on by shareholders and other customary and important disclosures.

      I look forward to seeing you at the annual meeting.  Whether or not you
plan to attend the annual meeting, please sign and return the enclosed proxy so
that your vote will be counted.

                                     Sincerely,

                            SOLICITATION OF PROXIES

      We are providing these proxy materials in connection with the
solicitation of proxies by the Board of Directors of Wausau-Mosinee Paper
Corporation for use at the 2004 annual meeting of shareholders, including any
adjournment thereof.  The annual meeting will be held at 2:00 p.m. on April 22,
2004, at The Wausau Club, 309 McClellan Street, Wausau, Wisconsin.

                               VOTING PROCEDURES

YOUR VOTE

      Your vote is important.  Whether or not you plan to attend the annual
meeting, please sign, date, and return the enclosed proxy promptly in order to
be sure that your shares are voted.  You may revoke your proxy at any time
before it is voted by giving written notice to the Secretary of the Company at
our principal office in Mosinee, Wisconsin, by filing another duly executed
proxy bearing a later date with the Secretary, or by giving oral notice at the
annual meeting.

      All shares represented by your properly completed proxy which have been
submitted to the Company prior to the meeting (and which have not been revoked)
will be voted in accordance with your instructions.  IF YOU DO NOT INDICATE HOW
YOUR SHARES SHOULD BE VOTED ON A PROPOSAL, THE SHARES REPRESENTED BY YOUR
PROPERLY COMPLETED PROXY WILL BE VOTED AS THE BOARD RECOMMENDS.

      If any matters other than those described in this proxy statement are
properly presented at the annual meeting for consideration, including, among
other things, consideration of a motion to adjourn the meeting to another time
or place, the persons named as proxies in the proxy form furnished to you by
the Board will have discretion to vote on those matters according to their best
judgment to the same extent as you would be entitled to vote.  As of the date
of this proxy statement, we do not anticipate that any other matters will be
presented to the annual meeting.

SHAREHOLDERS ENTITLED TO VOTE

      General.  Shareholders at the close of business on the record date,
February 19, 2004, are entitled to notice of and to vote at the annual meeting.
Each share is entitled to one vote on each proposal properly brought before the
annual meeting.  Votes cast by proxy or in person at the annual meeting will be
tabulated by an inspector of elections appointed by the Board.  On the record
date, there were 51,651,251 shares of common stock outstanding.

      "Street Name" Accounts.  If you hold shares in "street name," you will
receive voting instructions from the broker that is the holder of record of
your shares.  In some cases, your broker may be able to vote your shares even
if you provide no instructions (such as the election of directors), but on
other matters your broker may vote the shares held for you only if you provide
voting instructions (such as the proposal to approve amendments to our 2000
Stock Incentive Plan).  Shares for which a broker does not have the authority
to vote are recorded as a "broker non-vote" and are not counted in the vote by
shareholders.

      Dividend Reinvestment Plan and Common Stock Purchase Plan Participants.
If you are a participant in the Dividend Reinvestment and Stock Purchase Plan
or Common Stock Purchase Plan, your proxy will also serve to direct the plan
administrator to vote any shares of common stock held for you under either plan
at the close of business on the record date.  Shares beneficially owned by
participants in the plans for which no proxy or other
                                        1
voting directions are received will not be voted.  Your form of proxy will
permit you to vote the shares held in the plan.

      401(k) Plan Participants.  If you are a participant in our 401(k) plan
you may vote an amount of shares equivalent to the interest in our common stock
credited to your account as of the record date.  Your proxy will serve as
voting instructions for the trustee of the 401(k) plan.  If you own shares
through the 401(k) plan and do not vote, the plan trustees will vote the plan
shares in the same proportion as shares for which instructions were received
under the plan.  Your form of proxy will permit you to vote the shares held in
the plan.

QUORUM, REQUIRED VOTE, AND RELATED MATTERS

      Quorum.  A quorum is present if a majority of the votes entitled to be
cast on a proposal are represented at the annual meeting in person or by proxy.
For purposes of determining a quorum, shareholders who are present in person or
are represented by proxy, but who abstain from voting, are considered present
and count toward the determination of the quorum.  Shares reported as broker
non-votes are also considered to be shares present for purposes of determining
whether a quorum is present.

      Election of Directors.  Directors are elected by a plurality of the votes
cast.  For this purpose, a "plurality" means that the individuals receiving the
largest number of votes are elected as directors, up to the maximum of the two
directors to be chosen at the annual meeting.  You may vote in favor of the
nominees specified on the accompanying proxy form or may withhold your vote as
to one or more of such nominees.  Shares withheld or not otherwise voted in the
election of directors (because of abstention, broker non-vote, or otherwise)
will have no effect on the election of directors.

      Approval of 2000 Stock Incentive Plan.  Proposal No. 2 (see "Proposal No.
2 - Approval of Amended 2000 Stock Incentive Plan") will be approved if a
majority of the shares of stock represented and voted at the annual meeting
vote for approval, provided that a majority of the outstanding shares of stock
are voted on the proposal.  Therefore, broker non-votes will have an effect on
Proposal No. 2 only if a majority of the outstanding shares are not otherwise
voted on the proposal.

      All Other Proposals.  As of the date of this proxy statement, we do not
anticipate that any other proposals will be brought before the annual meeting.
Generally, proposals other than the election of directors which are brought
before the meeting will be approved if the votes cast for the proposal exceed
the votes cast against the proposal.

                    PROPOSAL NO. 1 - ELECTION OF DIRECTORS

GENERAL INFORMATION

      The Nomination Process.  Nominations for director are recommended to the
Board by the Corporate Governance Committee.  The Committee operates under a
charter which is available under "Corporate Overview - Corporate Governance"
on the Company's website at www.wausaumosinee.com.  All members of the
Committee are independent directors under New York Stock Exchange, Inc.
("NYSE") listing standards.

      Candidates for election to the Board may be identified for initial
consideration by the Committee from a wide variety of potential sources.  For
example, the Committee will consider candidates for nomination from among
incumbents whose term will expire at the next annual meeting, persons
identified by other members of the Board, executive officers, shareholders, and
persons identified by a professional search firm should the Committee believe
it appropriate to engage such a firm to assist it.  To recommend an individual
for consideration, a shareholder should mail or otherwise deliver a written
recommendation to the Committee not later than the December 1 immediately
preceding the annual meeting for which the individual is to be considered for
inclusion as a nominee of the Board.  At a minimum, a shareholder
recommendation should include the individual's current and past business or
professional affiliations and experience, age, stock ownership, particular
                                        2
qualifications, and such other information as the shareholder deems relevant to
assist the Committee in considering the individual's potential service as a
member of the Board.

      Qualifications.  In reviewing potential nominees, the Committee will
consider the age, skills, and experience of current Board members and the
requirement under the guidelines that a majority of the Board members must be
independent, as determined in accordance with NYSE listing standards.  At a
minimum, nominees must satisfy the qualification requirements included in our
Corporate Governance Guidelines (which is also posted on our website),
including the provision that no person may be elected a director if that
person has attained age 70 as of the date of the election.  All potential
nominees submitted to or identified by the Committee will be evaluated on a
similar basis for their level of qualifications and experience.

      The Committee believes that persons recommended by it to the Board should
possess strong intellectual skills, have had a successful career in business,
higher education, or a profession which demonstrates an ability to manage a
complex organization, have a reputation for personal and professional
integrity, be able to exercise a sound and independent business judgment, and
understand the economic, financial, and operational issues to be addressed by
the Company.  Directors whose terms of office will expire at the next annual
meeting are considered by the Committee on the basis of these qualities and
also on the basis of their service to the Company during their term in office.

ELECTION OF DIRECTORS

      The Board has determined that it is appropriate to reduce the number of
directors to seven from eight effective with the annual meeting, divided into
three classes consisting of three Class I, and two Class II and Class III
directors, respectively.  One class of directors is to be elected at each
annual meeting of shareholders to serve a three-year term.  Any director
appointed by the Board to fill a newly created directorship is required to
stand for reelection by the shareholders at the first annual meeting following
his or her appointment by the Board.

      At the annual meeting, shareholders will be asked to elect two Class II
directors for terms of office which will expire at the annual meeting of
shareholders to be held in 2007.  Richard L. Radt and Harry R. Baker have each
reached mandatory retirement age under our Corporate Governance Guidelines and,
accordingly, will not be candidates for reelection to the Board.

      Upon recommendation of the Corporate Governance Committee, the Board has
nominated Dennis J. Kuester for reelection, and Andrew N. Baur for election, as
Class II directors.  Mr. Baur was recommended to the Committee by an
independent director of the Company; no third party was engaged by the
Committee to assist it in its search for nominee candidates.  In the event one
or both of the nominees should become unable or unwilling to be a nominee for
election at the annual meeting, it is the intention of the proxies to vote for
such substitute or substitutes as may be designated by the Board.

      THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE ELECTION OF THE TWO
NOMINEES FOR CLASS II DIRECTOR.  The following table sets forth information
concerning the business background and experience of the Board nominees and all
continuing directors.  Unless specified, all current positions listed for a
nominee or director have been held for at least five years.  Directors whom the
Board has determined are independent under the criteria of the NYSE listing
standards (or nominees who will meet such criteria) are denoted by an asterisk
(*).

BOARD OF DIRECTORS

Board and the committees on which they served during the last fiscal year.
                                        4

      Meetings of Non-management Directors.  The Board's non-management
directors meet in executive session following each February Board meeting and
establish a schedule of additional meetings.  The non-management directors must
meet at least twice each year under the Company's Corporate Governance
Guidelines.  At their February, 2004, meeting, the non-management directors
selected Gary W. Freels to preside over their meetings.  Shareholders and
others may communicate directly with Mr. Freels or any other non-management
directors by following the procedures set forth in the following paragraph.

      Communicating with the Board.  Shareholders and others may communicate
with the Board by writing to the Chairman at the Company's corporate office,
1244 Kronenwetter Drive, Mosinee, Wisconsin  54455-9099.  Individual directors
may also be contacted in writing at the same address.  Mail may be opened and
sorted before forwarding to the director to whom the mail was addressed.

      Attendance at Annual Meetings.  The Board has an informal policy under
which all directors are expected to attend the annual meeting of shareholders.
Each of our directors attended the annual meeting held in 2003.

CORPORATE GOVERNANCE GUIDELINES AND COMMITTEES OF THE BOARD OF DIRECTORS

      Our Corporate Governance Guidelines set forth basic principles and
guidelines concerning the qualifications and responsibilities of directors,
Board committees, and other matters.  In addition, we have adopted a code of
business conduct and ethics for all employees and a separate code of ethics
which also covers our CEO and senior financial officers.  The Corporate
Governance Guidelines, committee charters, and codes of ethics are posted in
the "Corporate Overview - Corporate Governance" section of our website, at
www.wausaumosinee.com.  A copy of these documents may also be obtained from the
Secretary of the Company by writing to our corporate office.

      Our Corporate Governance Guidelines provide that the Company shall have
Audit, Compensation, and Corporate Governance Committees in addition to any
other committees the Board considers appropriate.  Each of the members of the
following committees satisfies the criteria for independence under applicable
rules of the Securities and Exchange Commission ("SEC") and the current and
recently adopted NYSE listing standards.

      Audit Committee.  The Audit Committee, established in accordance with
Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), assists the Board in monitoring (1) the integrity of the
financial statements of the Company, (2) the independent auditor's
qualifications and independence, (3) the performance of the Company's internal
audit function and independent auditors, and (4) compliance by the Company with
legal and regulatory requirements.  The Committee has the sole authority to
appoint or replace the Company's independent auditor.  Members of the Committee
may not serve on the audit committees of more than two other public companies.
The members of our Audit Committee also satisfy the additional NYSE and SEC
rules for independence applicable to audit committees of listed companies.

      Mr. Baker (Chairman), Mr. Alexander, Mr. Freels, and Mr. Kuester serve on
the Audit Committee.  The Committee met 10 times in 2003.  See "Report of the
Audit Committee and Related Matters," for the report of the Audit Committee and
other information relating to the selection of, and fees paid to, the
independent auditor.

      Compensation Committee.  The Compensation Committee is appointed by the
Board to (1) discharge the Board's responsibilities relating to compensation of
the Company's directors and officers, and (2) produce an annual report on
executive compensation for inclusion in the Company's proxy statement.  The
Committee has overall responsibility for approving and evaluating director and
officer compensation plans, policies, and programs, and approves the granting
of stock incentives.  The Committee's report on the Company's compensation
policies for executive officers is included in this proxy statement under the
subcaption "Executive Compensation - Report of the Compensation Committee."
Mr. Alexander (Chairman), Mr. Baker, Mr. Freels, and Mr. Smith serve as members
of the Compensation Committee.  The Committee met three times in 2003.
                                        5
      Corporate Governance Committee.  The Corporate Governance Committee is
appointed by the Board to (1) identify individuals qualified to become Board
members, and to recommend to the Board the director nominees for the next
annual meeting of shareholders, (2) recommend to the Board the Corporate
Governance Guidelines applicable to the Company, (3) lead the Board in its
annual review of the Board's performance, and (4) recommend to the Board
director nominees for each committee.  Mr. Freels (Chairman), Mr. Alexander,
Mr. Kuester, and Mr. Smith serve on the Corporate Governance Committee.  The
Committee met five times in 2003.

COMPENSATION OF DIRECTORS

      Each director is paid a retainer of $2,000 per month and $1,000 for each
meeting of the Board attended.  In addition, the chairmen of the Executive and
Audit Committees each receive an annual retainer of $5,000 and the chairmen of
the Corporate Governance and Compensation Committees each receive an annual
retainer of $3,000.  Directors receive a meeting fee of $500 for each meeting
of a Board committee attended.  Upon initial election to the Board, a director
receives an option to purchase 15,000 shares of our stock at the current market
price.  Upon reelection to a three-year term, a director receives an option to
purchase 10,000 shares of our stock at the current market price.  Mr. Smith
participates in our retiree health insurance plan and the other directors who
are officers of the Company receive salaries and benefits related to their
duties.  No other director received more than the standard arrangements
described above.

      The Directors' Deferred Compensation Plan provides that directors may
elect each year to defer some or all of the fees otherwise payable in cash
during the year.  Amounts deferred become payable in cash in a lump sum or in
quarterly installments after a director's termination of service.  In the event
a director's service terminates because of a change of control of the Company,
as defined in the plan, payment of all deferred amounts will be made in a lump
sum.  During the period in which payment is deferred, a director may elect that
the deferred fees be credited with interest at the prime rate in effect as of
each calendar quarter at The Chase Manhattan Bank of New York, or that the
deferred fees be converted into common stock equivalent units.  If common stock
equivalent units are elected, the director's account is also credited with
stock equivalent units representing the shares of our common stock which could
have been purchased with the cash dividends which would have been paid had the
units been actual common stock.  Stock equivalent units are converted to cash
based upon the fair market value of our common stock at the time of
distribution.  During 2003, Mr. Alexander, Mr. Baker, Mr. Howatt, Mr. Freels,
and Mr. Kuester participated in the plan and deferred all or a portion of the
retainer or meeting fees otherwise payable to them.

      Directors who began service prior to January 1, 2003, and serve on the
Board for at least five years prior to termination of service are eligible to
receive a monthly benefit equal to the monthly retainer and meeting fees in
effect at termination of service.  Benefits will be paid for a period of time
equal to the retired director's period of service on the Board, including
service on the board of directors of Mosinee Paper Corporation prior to
December 17, 1997.  Retirement benefits terminate at death and are accelerated
in the event of a change of control of the Company, as defined in the policy.
Directors who began service after December 31, 2002, are not eligible for
retirement benefits.

DETERMINATION OF INDEPENDENCE OF DIRECTORS

      Our Corporate Governance Guidelines provide that a majority of the Board
and all members of our Audit, Compensation, and Corporate Governance Committees
will consist of independent directors, as determined in accordance with NYSE
listing standards.  Five of our Board members satisfy the requirements for
independence under current and recently adopted NYSE listing standards (Mr.
Baker, Mr. Alexander, Mr. Freels, Mr. Kuester, and Mr. Smith).  If the Board's
nominees are elected at the annual meeting, we believe that five of seven
directors, including Mr. Baur, will satisfy these independence criteria.

      During 2003 we engaged in various business transactions with companies
for which some of our directors serve as directors or officers.  Each of these
transactions was done in the ordinary course of business and at prices and on
terms prevailing at the time for comparable transactions with unrelated
persons.  The Board has adopted categorical standards to assist it in
determining whether any of such transactions create a material
                                        6
relationship which precludes independence under NYSE listing standards.  In
general terms, and absent other factors, the Board's categorical standards
provide that a customer relationship is not material if the Company does not
account for more than 2% of the revenue of the director's business and not
more than 2% of the Company's revenue is derived from the director's business.
Similarly, in the case of a lending relationship, absent other factors, the
relationship is not material if the Company obtained the credit on the same
terms as other borrowers, the credit would have been available from other
lenders on comparable terms, and the interest and fees paid by the Company
does not exceed 2% of the lender's total income.  The Board's categorical
standards are posted in the "Corporate Overview - Corporate Governance"
section of our website, at www.wausaumosinee.com.

      Each of the Company's non-management directors meet the categorical
standards adopted by the Board.  None of our non-management directors receive
any compensation from the Company other than in his capacity as a director.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

      Section 16(a) of the Exchange Act requires directors and officers and
persons who own more than 10% of the common stock outstanding ("reporting
persons") to file reports of ownership and changes in ownership with the SEC
and the New York Stock Exchange.  Reporting persons are also required by SEC
regulations to furnish us with copies of all Section 16(a) forms filed by them
with the SEC.  We review copies of the Section 16(a) forms received by us or
rely upon written representations from certain of these reporting persons to
determine compliance with the Section 16(a) regulations for purposes of this
proxy statement.  Based on our review of these reports and the representations
of the reporting persons, we believe that all reports required to be filed by
Section 16(a) were filed on a timely basis.

               REPORT OF THE AUDIT COMMITTEE AND RELATED MATTERS

AUDIT COMMITTEE REPORT

      During the 2003 fiscal year, the Audit Committee met at various times
with senior members of the Company's financial management team and the
Company's independent auditor to review and discuss the Company's financial
statements (including critical accounting policies, significant accounting
issues, and assumptions made in connection with those policies and preparation
of the financial statements), financial management issues, and the Company's
system of internal controls.

      The Audit Committee met with the Company's senior financial management
team and the independent auditor to review the Company's audited financial
statements for the 2003 fiscal year prior to their issuance.  At that meeting,
the Committee received assurances from senior financial management that all
financial statements had been prepared in accordance with accounting principles
generally accepted in the United States.  In addition, the Committee asked the
independent auditor to address and respond to questions concerning the audited
financial statements, the audit process, and other related matters.  This
discussion centered on the following questions posed by the Committee to the
independent auditor:

 o    Are there any accounting judgments made by management in preparing the
      financial statements that would have been made differently had the
      auditor prepared and been responsible for the financial statements?

 o    Based on the auditor's experience and its knowledge of the Company, do
      the Company's financial statements fairly present to investors, with
      clarity and completeness, the Company's financial position and
      performance for the reporting period in accordance with generally
      accepted accounting principles and Securities and Exchange Commission
      ("SEC") disclosure requirements?

 o    Based on the auditor's experience and its knowledge of the Company, has
      the Company implemented all internal controls and internal audit
      procedures that are appropriate for the Company?

      In connection with its review of the audited financial statements, the
Audit Committee discussed with the independent auditor the independence of the
firm under SEC rules for the purposes of expressing an opinion on the Company's
financial statements, and considered whether the provision of nonaudit services
is compatible with maintaining the auditor's independence.  The Committee
received from the independent auditor the written disclosure and the letter
relating to the independence of the firm required by the Independence Standards
Board Standard No. 1 (Independence Discussions with Audit Committees).  The
Committee also discussed with the independent auditor the matters required to
be discussed pursuant to Statement on Auditing Standards No. 61 (Communication
With Audit Committees).

      Management has the primary responsibility for the Company's financial
statements and the overall reporting process.  It is not the duty of the Audit
Committee to conduct auditing or accounting reviews or procedures.  The
Committee acts only in an oversight capacity and it necessarily relies on the
work and assurances provided by management and the independent auditor and it
therefore does not have an independent basis to
                                        9
determine whether management has maintained appropriate accounting and
financial reporting principles or policies or appropriate internal controls and
procedures.  Accordingly, the Committee's reviews of the Company's financial
statements and its discussions with the Company's senior financial management
team and the independent auditor do not guarantee that the Company's financial
statements have been prepared in accordance with accounting principles
generally accepted in the United States or that the audit has been carried out
in accordance with auditing standards generally accepted in the United States.

      In reliance on the reviews and discussions described in this report and
on the report of the independent auditor, the Audit Committee recommended to
the Board of Directors that it approve the inclusion of the Company's audited
financial statements in the Company's Annual Report on Form 10-K for the fiscal
year ended December 31, 2003, for filing with the SEC.

AUDIT COMMITTEE PRE-APPROVAL POLICIES

      The Audit Committee is required to pre-approve audit and non-audit
services performed by the Company's independent auditor.  Under its pre-
approval policy, a schedule of specific audit, audit-related, and tax services
and their related fees received pre-approval in 2003 after review by the
Committee of appropriate detailed back-up documentation and receipt of
confirmation from management and the independent auditor that each non-audit
service included in the schedule may be performed by the independent auditor
under applicable SEC and professional standards.  Any services not included in
the pre-approved schedule of services and fees must be specifically pre-
approved by the Committee.  To ensure prompt handling of unexpected matters,
the Committee has delegated to the chairman, and in his absence, to Mr. Freels,
the authority to grant pre-approvals for services, provided that any such
pre-approvals must be presented to the full Committee at its next meeting.

      In granting approval for a service, the Audit Committee (or the
appropriate designated Committee member) considers the type and scope of
service, the fees, whether the service is permitted to be performed by an
independent auditor, and whether such service is compatible with maintaining
the auditor's independence.

INDEPENDENT AUDITOR AND FEES

      The Audit Committee appointed Deloitte & Touche LLP  ("Deloitte") as
independent auditor to audit the books, records, and accounts of the Company
for the fiscal year ended December 31, 2003.  Representatives of Deloitte will
be present at the annual meeting and will have an opportunity to make a
statement or respond to appropriate questions.

*  Certain amounts have been reclassified from previous disclosure to conform
   to changes in SEC disclosure requirements.

   statements, as well as work generally only the independent auditor can
   reasonably be expected to provide, such as statutory audits and review of
   SEC filings.
(2)Audit-related fees consisted principally of audits of employee benefit plans
   and advisory services relating to compliance with requirements of Sarbanes-
   Oxley Act of 2002.
(3)Tax fees for 2003 represents fees of $232,835 related to tax compliance (tax
   returns, refunds, and payment planning) and fees of $340,752 for tax

   benefits to the Company in excess of the fees paid.

RELATIONSHIPS WITH PREVIOUS INDEPENDENT AUDITORS

      Arthur Andersen LLP ("Andersen") was dismissed as the Company's
independent auditor on June 18, 2002.  As the Company reported in its Form 8-K
of such date:

      o  the report of Andersen on the Company's financial statements for
         the fiscal year ended December 31, 2001 did not contain any adverse
         opinion or disclaimer of opinion, nor was it qualified or modified as
         to uncertainty, audit scope, or accounting principles;

      o  in connection with the audit for the 2001 fiscal year and through
         June 18, 2002, there were no disagreements with Andersen on any matter
         of accounting principles or practices, financial statement disclosure,
         or auditing scope or procedure which would have caused Andersen to
         make reference to such matters in its report on the financial
         statements for those years if not resolved to its satisfaction;

      o  during the fiscal year ended December 31, 2001, and through the
         period ended June 18, 2002,

(1)Includes compensation deferred by officers under 401(k) plan and Executive Officers' Deferred Compensation Plan.
(2)Performance units granted pursuant to 2000 Stock Incentive Plan.  All grants are conditioned upon the approval by
   shareholders of the amended plan presented to annual meeting, the satisfaction of Company performance criteria in
   2004, and service by the grantee through December 31, 2005.  See "Proposal No. 2 - Approval of Amended 2000 Stock
   Incentive Plan."  Value indicated in table is based on the units granted and the closing price of the Company's
   stock on December 19, 2003, the date of grant.  The number of shares attributable to the performance units granted
   in 2003 and the number of shares attributable to performance units held as of December 31, 2003, by the executive
   officers named in the table were:  Mr. Howatt, 3,933 shares; Mr. Carlson, 1,942 shares; Mr. Davis, 1,633 shares; Mr.
   Doescher, 1,524 shares; and Mr. Urbanek, 1,470 shares.  Holders of performance units are also entitled to dividend
   equivalents which result in additional performance units being credited to the named individuals on each cash
   dividend payment date based upon the cash dividend rate and the value of the Company's stock on such date.
(3)50% of the options granted in 2002 are subject to satisfaction of financial performance conditions by the Company in
   fiscal 2004.  Because financial performance conditions were not satisfied in 2003, options with respect to 50% of
   the shares granted to each named officer in 2002 have lapsed.
(4)Options with respect to 12,000 shares granted in 2001 lapsed because financial performance conditions were not
   satisfied.
(5)Director's fees of $30,000, 401(k) contribution of $5,100, and credits of $21,095 payable under the Company's
   flexible benefit plan.  Mr. Howatt's fees were deferred under the Deferred Compensation Plan for Directors described
   under the caption "Director Compensation."
(6)Contributions of $5,100 under 401(k) plan and credits payable under the Company's flexible benefit plan to: Mr.
   Carlson, $1,812; Mr. Doescher, $7; and Mr. Urbanek, $912.
(7)Reimbursement for taxes under relocation policy.
(8)Includes $20,160 as reimbursement of moving expenses under relocation policy.

RETIREMENT BENEFITS

      Our retirement plan covers all salaried employees and bases a
participant's pension on the value of a hypothetical account balance in the
plan.  A participant will receive an annual credit to his account equal to
4.25% of covered compensation up to the Social Security taxable wage base and
8.5% of the covered compensation in excess of the taxable wage base, plus an
interest credit on all prior accruals equal to the 30-year U.S. Treasury rate.
For 2003, a discretionary additional credit of 16% was also approved by the
Board.  The benefit payable under the plan is determined by converting the
hypothetical account balance credits into annuity form.

      Executive officers also participate in a nonqualified supplemental
retirement plan under which benefits are determined by compensation without
regard to limitations contained in the cash balance plan.  The supplemental
plan will provide an executive officer with a retirement benefit equal to 50%
of his average salary and bonus upon retirement at age 62 after 10 years of
service as an executive officer.  The supplemental plan provides for an offset
of benefits payable under the cash balance plan.  Accrued benefits under the
supplemental plan will be paid in a lump sum in the event of a change of
control of the Company, as defined in the supplemental plan.

      Based on average covered compensation as of December 31, 2003, the
following estimated single life annuity benefits would be payable from the cash
balance and supplemental retirement plans upon retirement at normal retirement
age under the cash balance plan (age 65) to the following executive officers:

(1) Years of service as an executive officer under the supplemental plan.
    Vesting under the supplemental plan with respect to the listed officers
    requires attainment of age 55 and 10 years of service as an executive
    officer.  All officers are vested in their accrued benefit under the cash
    balance plan.

      Our Executive Deferred Compensation Plan permits an executive officer of
the Company to elect to defer up to 50% of his base salary and 100% of his
incentive compensation.  The amounts deferred are credited with interest at the
prime rate from the date of deferral.  A Participant's accrued balance is
distributed on a date elected by the participant, but in no event later than
age 65.  Distribution will be made pursuant to an installment method of up to
120 months elected by the Participant, or in a lump sum payable not later than
the month in which the participant attains age 65.  The plan is unfunded.

REPORT OF THE COMPENSATION COMMITTEE

      The Compensation Committee establishes and reviews base salaries of
executive officers and is responsible for the establishment and implementation
of executive bonus and incentive programs, general compensation policies, and
grants under stock option, SAR and dividend equivalent plans.  This report
describes the policies of the Compensation Committee as in effect for the 2003
fiscal year.

      General.  The Committee's compensation policy is designed to align the
interests of executives and shareholders by making a significant portion of
each executive officer's compensation package directly related to the annual
performance of the Company and the performance of the Company's common stock.
The total compensation paid to executive officers and the retirement and other
fringe benefits provided by the Company are designed to offer a level of

compensation which is competitive with other companies in the paper industry.
Some, but not all, of the companies used for purposes of compensation
comparisons are included in the 39 companies which, in addition to the Company,
comprise the Media General index of paper companies' stock performance under
the caption "Stock Price Performance Graph."  The Committee makes compensation
comparisons only with those companies whose operations are similar to the
Company or which have operating units which are similar to the Company.  Given
the disparity in size between companies which operate in the paper industry and
the difficulty in determining the precise duties of executive officers of other
companies, it is difficult to draw exact comparisons with the compensation
policies of other companies.  The determination of executive compensation is,
therefore, subjective.

      The Compensation Committee is aware that, except for certain plans
approved by shareholders, Section 162(m) of the Internal Revenue Code of 1986,
as amended, limits deductions to $1 million for compensation paid to the CEO
and each of the four most highly paid executive officers named in the summary
compensation table who are officers on the last day of the year.  No
compensation paid in 2003 exceeded the deductible limit.  The Committee reviews
this limit and its application to the Company's compensation policies as part
of its compensation policy.
                                        15
      Base Compensation.  The Compensation Committee does not rely on specific
salary and benefit comparisons, but does periodically consider and review
surveys of paper industry compensation and may retain independent consultants
in order to gauge the relationship of its executive officers' base salaries and
benefit levels to the levels of comparable paper companies.  Annual increases
in the base salary of each of the Company's executive officers are determined
in accordance with the Committee's policy of maintaining competitive salary
levels with other paper industry companies (as discussed above), and individual
job performance.

      Individual job performance in the prior fiscal year is the most important
factor considered by the Compensation Committee in annual reviews and in
determining appropriate increases in base salary.  The CEO annually assesses
the job performance of executive officers who report to him.  The CEO's base
salary is determined by the Committee on the same basis as that of the
Company's other executive officers, except that the Committee annually
establishes performance criteria for the CEO and reviews his performance.
Individual performance criteria generally include an evaluation of the
performance of the individual officer's fundamental duties and responsibilities
and the extent to which specific individual performance goals used to measure
incentive compensation have been achieved.

      Incentive Compensation Based on Financial Performance of the Company and
Individual Performance.  The Company's compensation policies are intended to
subject a significant portion of executive officer compensation to risks
relating to the Company's achievement of annual financial objectives.
Incentive compensation is predicated on the degree to which the Company
achieves targeted returns on capital employed and achievement of individual
performance objectives related to increased Company financial performance.

      Criteria used in the assessment of Mr. Howatt's eligibility for incentive
compensation in 2003 based upon individual objectives included the achievement
of targeted rates of return on approved capital projects, increases in mill
operating efficiencies, and the achievement of reductions in targeted

components of working capital.  The individual performance objectives for
executive officers other than the CEO vary by individual job responsibilities.
They may include, for example, reductions in targeted components of working
capital, achievement of targeted rates of return on approved capital projects,
increases in productivity and volume of product shipped, revenues derived from
new products, and reduction in operating costs.

      Stock Based Compensation.  Executive officers participate in stock
option, SAR and dividend equivalent plans at various levels.  The Compensation
Committee has adopted, subject to shareholder approval at the annual meeting,
amendments to the Company's stock option plan in order to provide for the
granting of restricted stock and performance units payable in stock (see
"Proposal No. 2 - Approval of Amended 2000 Stock Incentive Plan").  The
Committee may impose restrictions as to exercise or vesting of grants.  The
Compensation Committee has not established formal criteria by which the size of
plan grants are determined, but the Committee considers the amount and terms of
each grant already held by an executive officer in determining the size and
terms of any new grant.  The value of these grants are principally related to
the long-term performance of the common stock and, therefore, provide an
identity of interests between executive officers and the shareholders.

      Compensation Committee Interlocks and Insider Participation.  The
directors making this report are the only directors who served on the
Compensation Committee in 2003.  Each member is an independent director under
NYSE listing standards and none is a former officer of the Company.

                           2000 STOCK INCENTIVE PLAN

      The principal features of the 2000 Stock Incentive Plan, as amended, are
summarized below.  The summary does not contain all of the information which
may be important to you.  A copy of the plan is attached to this proxy
statement as Exhibit A.

      THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR APPROVAL OF THE AMENDED
PLAN.

BACKGROUND AND PURPOSE OF PLAN AMENDMENTS

      Subject to shareholder approval at the 2004 annual meeting, the
Compensation Committee amended the plan in December, 2003 to change its name to
the "2000 Stock Incentive Plan" and to provide for the granting of restricted
stock, performance units, and dividend equivalents in addition to stock
options.  Performance units are essentially a form of restricted stock that
provide for the issuance of Company stock upon satisfaction of the performance
criteria.  The amendments do not increase the total number of shares which can
be issued under the plan.

      The amendments bring the plan in line with a large number of public
companies in providing for the grant of restricted stock and performance units.
Unlike many companies, however, we have not repriced any outstanding options
that are currently "underwater" (that is, the exercise price is higher than the
trading price of our stock)  and the amended plan will not have any effect on
options previously granted.  The amended plan relates only to the grants for
2004 and future years.

      The Compensation Committee believes the amended plan will better fulfill
the plan's purpose of attracting and retaining management-level employees and
directors and linking stock-based individual participant incentives directly to
our financial performance and increases in shareholder value.  As a consequence
of "underwater" options, many public company option programs have ceased to be
viewed by employees as providing tangible benefits or performance incentives.
Restricted stock and performance unit awards may provide somewhat greater
incentive for employees because the value of the award is not wholly dependent
on factors beyond their or the Company's control, such as general economic
conditions which can adversely affect stock prices even though the Company
performs well compared to the industry as a whole.  In addition, restricted
stock or performance units typically result in the employee acquiring a
tangible stake hold in the Company more quickly than from options, and provide
a more immediate incentive for performance and identity of interest with all
shareholders.

      Unlike the exercise of options, the Company receives no cash
consideration upon vesting of restricted stock or performance units.  However,
these awards typically result in grants which involve fewer shares of stock to
be issued than under option grants, thereby reducing shareholder dilution.  For
example, in the grants made by the Compensation Committee for 2004, which are
subject to shareholder approval of the plan, the number of shares to be issued
upon vesting is approximately 29% of the total shares subject to options
granted under similar performance criteria with respect to the 2003 fiscal
year.

ADMINISTRATION OF THE PLAN

      The plan is administered by the Compensation Committee, the members of
which are each independent under the NYSE listing standards.  The Committee is
authorized, in its sole discretion, to select those eligible employees who will
receive grants, determine the number of shares covered by such grants, impose
conditions on the vesting of grants, and administer and interpret the plan.

PERSONS ELIGIBLE TO RECEIVE GRANTS AND CONDITIONS OF VESTING

      Salaried employees of the Company or its subsidiaries who function in
management, administrative, or professional capacities, prospective salaried
employees who will function in one of those capacities and who have
                                        18
accepted offers of employment and our directors are eligible to participate in
the plan.  Grants will be made only to those eligible persons who are
selected by the Committee.  As of the date of this proxy statement, we
estimate that the number of eligible persons is less than 30.

      The Committee may establish various conditions or requirements which must
be satisfied before an option becomes exercisable or grants of restricted stock
or performance units vest.  These conditions may require the attainment of
certain financial goals by the Company, the passage of stated periods of time,
or any other conditions the Committee believes are reasonably related to the
achievement of the purpose of the plan.  Performance units require achievement
of specified performance criteria and may also require specified additional
service by the grantee.  Restricted stock and performance units will generally
vest upon the death, disability or retirement of a participant or a change in
control and will be forfeited upon termination for cause.  The Committee may
also waive or modify any such conditions in its sole discretion, subject to the
limitations of Section 162 of the Internal Revenue Code of 1986, as amended
(the "Code"), on performance-based compensation.

         the amended plan.  Dollar value is based on date of grant, December
         19, 2003 ($13.22 per share).

OPTIONS

      The following paragraphs describe the options which may be granted.  The
provisions of the plan relating to options were not affected by the plan
amendments.

      General.  Options awarded to employees under the plan may be either
incentive stock options ("ISOs") under Code Section 422 or options which do not
satisfy the requirements of the Code for ISOs ("non-qualified options").

      Exercise Price.  All options must be awarded at an option price which is
not less than the fair market value of the common stock on the date the option
is awarded.  For purposes of the plan, the "fair market value" of a share of
common stock generally means the average of the highest and lowest sales prices
as reported on the NYSE Composite Tape.
                                        19
      Payment for Options.  No consideration is received by us when an option
is awarded.  Upon exercise of an option, we will receive payment for the shares
in cash or, with the consent of the Committee, an optionee may elect to deliver
common stock owned by the optionee or to have shares withheld which have a fair
market value equal to the exercise price.

      Term and Exercise Periods of Options.  The Committee may establish the
term of any option, although all ISOs must be exercised within ten years of
their date of award and all non-qualified options must be exercised within
twenty years of their date of award.  Options must generally be exercised
within three months of the optionee's termination of employment, although
extended exercise periods of up to two years are provided for in the case of

retirement, death or disability.  A change in control may also extend the
exercise period of an option and will trigger the right to surrender an option
for cash on terms described in the plan.  Options are not transferable, except
upon the death of an optionee.

RESTRICTED STOCK, PERFORMANCE UNITS, AND DIVIDEND EQUIVALENTS

      Restricted Stock.  Restricted stock granted under the plan involves the
transfer of stock to a participant subject to the satisfaction of any service
or performance conditions the Committee determines.  In the event the
conditions are not satisfied, the restricted stock is forfeited and the
certificates cancelled.  Stock certificates representing the restricted stock
will usually be held in escrow during the vesting period, but the participant
is entitled to vote the shares.  Cash dividends paid on the stock may either be
distributed or held in escrow subject to the vesting of the underlying shares.

      Performance Units.  Performance units may be paid, in the Committee's
discretion, in shares of stock on a one-to-one basis or in cash upon
satisfaction of the service or performance conditions imposed by the Committee
in connection with the grant.  In connection with a grant of performance units,
the Committee may also grant dividend equivalents which provide for the
additional crediting of units for the benefit of a participant based upon the
fair market value of the stock on the date of dividend payment and the cash
dividends paid on the number of shares equal to the units then held by the
participant.  Dividend equivalents will be subject to the same conditions on
vesting as the performance units to which they are related.

FEDERAL INCOME TAX CONSEQUENCES

      The following is a general summary of the principal federal income tax
consequences associated with the award and exercise of options and the award
and vesting of restricted stock and performance units under the plan.  This
discussion is based on the Code as in effect on the date of this proxy
statement.

      Incentive Stock Options.  An optionee will not generally recognize income
upon the grant of an ISO and will not generally recognize income upon exercise
of the option, provided the optionee is an employee of the Company or a
subsidiary at all times from the date of grant until three months prior to
exercise.  However, the amount by which the fair market value of the shares on
the date of exercise exceeds the exercise price will be includable for purposes
of determining any alternative minimum taxable income of an optionee.  If an
optionee who has exercised an incentive stock option sells the shares acquired
upon exercise more than two years after the grant date and more than one year
after exercise, capital gain or loss will be recognized equal to the difference
between the sales price and the exercise price.  An optionee who sells the
shares within two years after the grant date or within one year after exercise
will recognize ordinary compensation income in an amount equal to the lesser of
the difference between (a) the exercise price and the fair market value of the
shares on the date of exercise, or (b) the exercise price and the sales
proceeds.  Any remaining gain or loss will be treated as a capital gain or
loss.  We will be entitled to a federal income tax deduction equal to the
amount of ordinary compensation income recognized by the optionee in this case.
The deduction will be allowable at the same time the optionee recognizes the
income.

      Non-Qualified Options.  No income for federal tax purposes is required to
be recognized by an optionee at the time a non-qualified option is awarded.
Upon exercise of a non-qualified option, the optionee will recognize ordinary
income in an amount in excess of the fair market value of the shares on the
date of exercise
                                        20
over the option price.  Upon exercise of a non-qualified option by an
optionee, we are entitled to a deduction equal to the amount of the ordinary
income realized by the optionee.

      If an optionee sells shares received upon the exercise of such a non-
qualified option, the optionee will recognize capital gain income to the extent
the sales proceeds exceed the fair market value of the shares on the date of
exercise.  The capital gains are long-term in nature if the optionee has held
the shares for at least one year and a day prior to selling it.

      Restricted Stock and Performance Units.  A participant will recognize
ordinary income equal to the fair market value of the restricted stock as of
the date on which all conditions to vesting have been satisfied.  Ordinary
income is recognized upon distribution of performance units which will
typically occur promptly at vesting.  If approved by the Committee at the time
of grant, participants may elect to defer payment of the performance unit
shares and thereby defer the associated recognition of income for tax purposes.
The Company will be entitled to a deduction for income tax purposes as of the
date and in the same amount recognized by the participant as ordinary income.

SHARES AVAILABLE FOR ISSUANCE

      The plan authorizes the issuance of 3,322,238 shares of common stock, of
which 1,510,750 were subject to options or performance units outstanding on the
record date.  The amended plan does not increase the number of shares which may
be issued from the number originally approved by shareholders at the 2001
annual meeting.  The number of shares which may be awarded under an ISO in any
year is limited to that number which, when the option first becomes
exercisable, will have a value which is not in excess of $100,000.  No employee
may be awarded options with respect to more than 500,000 shares, or restricted
stock or performance units with respect to more than 100,000 shares (subject to
adjustment for future stock splits, stock dividends or other similar increases
in the number of shares outstanding) in any calendar year.  On the record date,
the closing price per share of the common stock as reported on the New York
Stock Exchange, was $13.31.

      If any option grant terminates without having been exercised in full or a
grant of restricted stock or performance units is forfeited, the number of
shares subject to the grant will remain available for future grants under the
plan.  Similarly, shares which are not delivered to a grantee because the
grantee elects to have shares withheld to pay the grantee's withholding tax or
in lieu of payment in cash of the exercise price of an option, or because an
optionee has delivered shares owned by the optionee in payment of the exercise
price of an option, will remain available for future grants.

      The number of shares as to which options, restricted stock, or
performance units may be granted under the plan will be adjusted to reflect
future stock splits, stock dividends or other similar increases in the number
of shares of common stock outstanding.  In addition, the Committee has the
authority to make such adjustment as it deems appropriate if there is any other
change in the capital structure of the Company.

AMENDMENT AND TERMINATION OF THE PLAN

      The plan may be amended by the Board at any time, but certain amendments,
such as an increase in the number of shares available under the plan and other
material modifications, may also require the approval of shareholders under the
rules of the NYSE.  The Board may not amend the plan in a manner which would
adversely affect the rights of the holder of a grant without the holder's
consent.

      The plan may be terminated at any time by the Board, but termination of
the plan cannot, without the grantee's consent, reduce or restrict the
grantee's rights under any award previously made under the plan.  Unless the
Board elects to terminate the plan at an earlier date, the plan will terminate
on June 21, 2010.
                                        21
VOTE REQUIRED FOR APPROVAL OF THE PLAN

      Approval of the amended plan requires a majority of the common stock
voted at the annual meeting, provided that the total votes cast represents a
majority of the total number of shares entitled to vote at the annual meeting
on the approval of the plan.  In the event the amended plan is not approved in
accordance with NYSE listing standards, the plan will continue as in effect
prior to December 19, 2003 and grants will be limited to stock options.

      All shareholders are requested to specify their vote on the enclosed form
of proxy.  If no specification is made, the proxy will be voted for approval of
the plan.

      THE BOARD RECOMMENDS THAT THE SHAREHOLDERS VOTE FOR THE APPROVAL OF THE
AMENDED PLAN.

                                 OTHER MATTERS

COSTS OF SOLICITATION

      In addition to solicitation by mail, our officers, directors and regular
employees may solicit proxies in person or by telephone, facsimile, electronic
mail, or other forms of communication.  Expenses in connection with the
solicitation of proxies, including the reasonable expenses of brokers,
fiduciaries, and other nominees in forwarding proxy material to beneficial
owners of our common stock, will be borne by us.

PROXY STATEMENT PROPOSALS

      Any shareholder who intends to present a proposal at the annual meeting
to be held in 2005 must deliver the written proposal to the Secretary of the
Company at our office in Mosinee, Wisconsin:

         o not later than November 18, 2004, if the proposal is submitted
           for inclusion in our proxy materials for the 2005 meeting pursuant
           to Rule 14a-8 under the Exchange Act; or

         o on or after January 22, 2005, and on or before February 21, 2005,
           if the proposal is submitted pursuant to our bylaws, in which case
           we are not required to include the proposal in our proxy materials.

Shareholders may present a proposal at the 2005 annual meeting for
consideration only if proper notice of the proposal has been given in
accordance with one of these requirements.  Nominations for director made from
the floor at the annual meeting of shareholders to be held in 2005 require
advance notice in accordance with the bylaws.

HOUSEHOLDING OF ANNUAL MEETING MATERIALS

      In accordance with notices sent to shareholders who share the same
address, we are sending only one annual report and proxy statement to that
address unless we receive contrary instructions from any shareholder at that
address.  This practice, which is called "householding," is designed to reduce
our printing and postage costs and the volume of duplicate information you
receive.  We expect that most banks, brokers and other nominee record holders
will also "household" proxy statements and annual reports for shareholders
whose accounts are held in street name.   Each shareholder will continue to
receive a separate proxy card.  We will promptly deliver a separate copy of our
proxy statement or annual report to any shareholder upon written or oral
request to the Secretary, Wausau-Mosinee Paper Corporation, 1244 Kronenwetter
Drive, Mosinee, WI 54455-9099, telephone: (715) 693-4470.

      Shareholders holding stock in their own name who wish to either request
or discontinue householding may contact the Secretary of the Company at the
address or telephone number listed in the preceding paragraph.
                                        22
Shareholders whose shares are held in street name and who wish to request or
Discontinue householding, should contact their bank, broker, or other nominee
Record holder.

                   AS AMENDED AND RESTATED DECEMBER 19, 2003


      SECTION 1.  PURPOSE.  The Plan has been adopted to enable the Company to
attract and retain management-level employees and directors and to link stock-
based individual participant incentives directly to the Company's financial
performance and increases in shareholder value.  The Plan has been amended and
restated effective as of December 19, 2003, to permit the awarding of
restricted stock and performance units as a means to further the purpose of the
Plan, to reflect the adoption of the Plan by the shareholders of the Company on
April 19, 2001, and to reflect changes in the corporate governance structure of
the Company.

      SECTION 2.  CERTAIN DEFINITIONS.  As used in this Plan, and in addition
to any terms elsewhere defined in this Plan, the following terms, when
capitalized, shall have the meanings set forth in this Section 2.

      SECTION 2.1. "BOARD" means the Board of Directors of the Company.

      SECTION 2.2. "CAUSE" means, with respect to any Grantee and unless
otherwise provided by the Committee, (a) "Cause" as defined in the related
Grant Agreement, or (b) if there is no definition of "Cause" in the related
Grant Agreement, then with respect to such Grantee, Cause means: (i) an
intentional failure to perform assigned duties;  (ii) willful misconduct in the
course of the Grantee's employment; (iii) breach of a fiduciary duty involving
personal profit or acts or omissions of personal dishonesty, including, but not
limited to, commission of any crime of theft, embezzlement, or misapplication
of funds; (iv) any intentional, reckless, or negligent act or omission to act
which results in the violation by the Grantee of any policy established by the

relating to Incentive Stock Options or any exchange or over-the-counter listing
standards for the Common Stock, any Shares with respect to which options
awarded under any Prior Plans are hereafter forfeited, expire, or are canceled
without delivery of Shares.

      SECTION 3.2. UNDELIVERED SHARES.  To the extent any Shares (a) subject to
an Option are not delivered to the Optionee (or the estate or other transferee
of such Optionee) because the Option is forfeited, expires, or otherwise
becomes unexercisable, or the Shares are not delivered because the Shares are
used to satisfy the applicable tax withholding obligation of the Optionee, or
(b) the Shares subject to a Grant of Restricted Stock are forfeited, such
Shares shall, except as may otherwise be prohibited by applicable regulations
relating to Incentive Stock Options or any exchange or over-the-counter listing

under the Plan.

      SECTION 3.3. EXERCISE OR WITHHOLDING USING SHARES.  If the Option Price
of any Option awarded under the Plan or any Prior Plan is satisfied by
tendering Shares to the Company (by actual delivery or attestation), only the
number of Shares issued to the Optionee (or the estate or other transferee of
such Optionee), net of the Shares tendered, shall be deemed to have been
delivered for purposes of determining the maximum number of Shares available
for delivery under the Plan, except as may otherwise be prohibited by
applicable regulations relating to Incentive Stock Options or any exchange or
over-the-counter listing standards for the Common Stock.  To the extent any
Shares are used to satisfy a Grantee's tax withholding obligation, such Shares
shall not be deemed to have been delivered for purposes of determining the
maximum number of Shares available for delivery under the Plan, except as may
otherwise be prohibited by applicable regulations relating to Incentive Stock
Options or any exchange or over-the-counter listing standards for the Common
Stock.

      SECTION 3.4. STOCK DIVIDENDS, ETC.  If the Company shall, after the
Effective Date, change the Common Stock into a greater or lesser number of
Shares through a stock dividend, stock split-up, or combination of Shares, then
(a) the number of Shares then subject to the Plan, but which are not then
subject to any outstanding Grant, (b) the number of Shares subject to each then
outstanding Option (to the extent not previously exercised), (c) the number of
Performance Units and Shares attributable thereto, and (d) the price per Share
payable upon exercise of each then outstanding Option, shall all be
proportionately increased or decreased as of the record date for such stock
dividend, stock split-up, or combination of Shares in order to give effect
thereto.  Notwithstanding any such proportionate increase or decrease, no
fraction of a Share shall be issued upon the exercise of an Option, and the

Shares subject to an Option, and Performance Units or Shares attributable
thereto shall be rounded to the nearest whole Share and the Option Price shall
be rounded to the nearest full cent.
                                        A-4
      SECTION 3.5. OTHER CHANGES.  If, after the Effective Date, there shall be
any change in the Common Stock or other change in the capitalization of the
Company other than through a stock dividend, stock split-up, or combination of
Shares, including, but not limited to, a change which results from a merger,
consolidation, spin-off, or other distribution of stock or property of the

Company, any reorganization (whether or not such reorganization is within the
meaning of Section 368 of the Code), or any partial or complete liquidation of
the Company, then if, and only if, the Committee shall determine that such
change equitably requires an adjustment in the number or kind of Shares and
Performance Units then subject to a Grant, the Option Price with respect to an
Option, or the number of Shares or class of stock remaining subject to the
Plan, such adjustment as the Committee shall determine is equitable and as
shall be approved by the Board shall be made and shall be effective and binding
for all purposes of such Grants and the Plan.  If any member of the Board
shall, at the time of such approval, be a Grantee, he shall not participate in
any action in connection with such adjustment.

      SECTION 4.  ADMINISTRATION OF THE PLAN.

      the Exchange Act (a "Non-Employee Director") and (ii) an "outside
      director" within the meaning of Section 162(m) of the Code (an "Outside
      Director"); provided, however, that in addition to the Committee's

      foregoing qualifications or adopt such other qualifications as are
      reasonably intended to result in (x) the award of Grants, and
      transactions with respect to the award or exercise of such Grants,
      satisfying an exemption from Section 16(b) of the Exchange Act, or any
      successor thereto, and (y) compensation recognized by Grantees qualifying
      as Qualified Performance-Based Grants.

            (B)   APPOINTMENT OF OTHER MEMBERS.  In the event that one or more

      Directors and Outside Directors.

            (C)   VALIDITY OF GRANTS.  Notwithstanding the qualifications for
      members of the Committee established in Section 4.1(a), any Grants made
      by the Committee in good faith and without the knowledge that one or more
      of its members did not satisfy such qualifications, shall be valid and

Dividend Equivalents subject to each Grant, and the Option Price associated

and conditions precedent to, the exercisability of each Option or vesting of
each Grant (including, without limitation, conditions with respect to the
passage of time, satisfaction of Performance Goals, satisfaction of individual
performance or other goals of the Grantee, restrictions on competitive
employment or satisfaction of Company policies, increase in Fair Market Value
of the Common Stock, and any other conditions which the Committee deems
reasonably related to the satisfaction of the purpose of the Plan), (d) at the
time of Grant or at any time thereafter impose such additional terms and
conditions on the exercise or vesting of such Grant as it deems necessary or
desirable for such Grant, or the exercise or vesting thereof, to be exempt
under Section 16(b) of the Exchange Act, and the regulations promulgated
thereunder, and to qualify as a Qualified
                                        A-5
Performance-Based Grant, (e) determine the form of each Grant Agreement and all
terms and conditions thereof with respect to each award, including adoption of
a formula providing for the award of Grants to Directors at specified
intervals, (f) interpret the Plan and the application thereof and establish
such rules and regulations as it deems necessary or desirable for the
administration of the Plan, (g) modify or cancel any Option or take such
action to cause the vesting or exercisability of any or all outstanding Grants
to become exercisable in part or in full for any reason at any time, subject to
the limitation of Section 15.1, provided, however, that no acceleration or
waiver of any Performance Goal shall be permitted with respect to a Qualified
Performance-Based Grant, except as permitted by Section 12, and (h) exercise
such other authority as is reasonably related to the administration of and/or
the fulfillment of the purpose of the Plan.  All actions, interpretations,
rules, regulations, and conditions taken or established by the Committee shall
be final, binding, and conclusive upon the Company and all Grantees.

      SECTION 4.3. ACTIONS BY THE COMMITTEE.  A majority of the members of the
Committee shall constitute a quorum.  In the absence of specific rules to the
contrary, action by the Committee shall require the consent of a majority of
the members of the Committee, expressed either orally at a meeting of the
Committee or in writing in the absence of a meeting.

no executive officer or other employee of the Company, and no other agent or
representative of the Company shall be liable for any act, omission,
interpretation, construction, or determination made in connection with the Plan
in good faith, and all such persons shall be entitled to indemnification and
reimbursement by the Company in respect of any claim, loss, damage, or expense
(including attorneys fees) arising therefrom to the full extent permitted by
law, except as otherwise may be provided in the Company's articles of
incorporation and/or bylaws, and under any directors' and officers' liability
insurance that may be in effect from time to time.

eligible individuals, as determined by the provisions of Section 5, as the
Committee may, from time to time and at any time, select.  Membership of an
employee or a prospective employee in a class of management, administrative, or
professional employees or election as a Director shall not, without specific
Committee action, entitle such person to receive an Option award.

      SECTION 6.2. GRANT AGREEMENT.  Each Option shall be evidenced by a Grant
Agreement, the terms of which may differ from other Grant Agreements.  Each
Grant Agreement evidencing an award of an Option by the Committee pursuant to
Section 6.1 shall be signed on behalf of the Company and, if so provided by the
Committee, the Optionee, and shall set forth with respect to the Option awarded

terms, conditions, and limitations set forth in the Plan.

      after the expiration of ten years from the date such Option is awarded.
      No Non-Qualified Stock Option shall be exercisable after the expiration
      of twenty years from the date such Option is awarded.

            (C)   PRICE.  The Option Price as to any Share subject to an Option

      Option is awarded.

            (D)   LIMITATIONS ON TRANSFERABILITY.  No Option shall be
      transferable by the Optionee other than by will or the laws of descent
      and distribution, nor can it be exercised by anyone other than the
      Optionee during the Optionee's lifetime.  No Option may be sold,
      transferred, assigned, pledged, hypothecated, encumbered, or otherwise
      disposed of (whether by operation of law or otherwise), or be subject to
      execution, attachment, or similar process.  Upon any attempt to so sell,
      transfer, assign, pledge, hypothecate, encumber, or otherwise dispose of
      any such award, such award and all rights thereunder shall immediately
      become null and void.

            (E)   EXERCISE.  Except as otherwise permitted by the Committee, or
      as provided in Section 6.4, or as elsewhere provided in this Section
      6.3(e), Options must be exercised, or shall be forfeited, in accordance
      with the following time limitations:

                  (I)   TERMINATION BY REASON OF DEATH.  If the Optionee incurs
            a Termination of Service by reason of death, any Option held by
            such Optionee on the Optionee's date of death may thereafter be
            exercised, to the extent it was exercisable on the date of the
            Optionee's death, for a period of one year from the date of death
            or until the expiration of the stated term of such Option,
            whichever period is shorter.

                  (II)  TERMINATION BY REASON OF DISABILITY.  If the Optionee
            incurs a Termination of Service by reason of Disability, any Option
            then held by such Optionee may thereafter be exercised to the
            extent it was exercisable on the date of such Termination of
            Service for a period of one year from the date of such Termination
            of Service or until the expiration of the stated term of such
            Option, whichever period is shorter.

                  (III) TERMINATION BY REASON OF RETIREMENT.  If the Optionee
            incurs a Termination of Service by reason of Retirement, any Option
            held by such Optionee may thereafter be exercised, to the extent it
            was exercisable on the date of the Optionee's Termination of
            Service, for a period of two years from the date of such
            Termination of Service or until the expiration of the stated term
            of such Option, whichever period is shorter.

                  (IV)  OTHER TERMINATION.  Unless otherwise determined by the
            Committee, if the Optionee incurs a Termination of Service for
            Cause, all Options then held by such Optionee shall terminate and
            may not be exercised from and after the effective date of such
            Termination of Service.  If an Optionee incurs a Termination of
            Service for any reason other than death, Disability, Retirement, or
            Cause, any Option then held by the Optionee, to the extent it was
            exercisable on the date of such Termination of Service, may be
            exercised for a period of three months from the date of such
            Termination of Service or until the expiration of the stated term
            of such Option, whichever period is shorter.

                  (V)   DEATH AFTER TERMINATION.  If the Optionee dies
            subsequent to a Termination of Service for any reason other than
            Cause, then, notwithstanding any other limitation on the exercise
            of the Optionee's Option set forth in subparagraphs (i), (ii),
            (iii), or (iv), any Option held by such Optionee on the Optionee's
            date of death may thereafter be exercised, to the extent it was
            exercisable on such date, for a period of one year from the date of
            death or until the expiration of the stated term of such Option,
            whichever period is shorter.
                                        A-7
                  (VI)  CHANGE IN CONTROL.  Notwithstanding any other provision
            of this Plan to the contrary, in the event the Optionee incurs a
            Termination of Service other than for Cause during the twelve-month
            period following a Change in Control, any Option held by such
            Optionee may thereafter be exercised by the Optionee, to the extent
            it was exercisable at the time of such Termination of Service, for

            (A) the longer of (1) one year from the date of such Termination of
            Service or (2) such other period as may be provided in the Plan
            from such Termination of Service, or (B) until expiration of the
            stated term of such Option, whichever period is shorter.

      Notwithstanding any other provisions of this Section 6.3(e), the
      exercisability of any Option shall be determined in regard to the status
      of the Optionee to which the Grant was attributable.  Options granted to
      an Optionee by reason of his Employment shall be exercisable in
      accordance with the foregoing provisions of subparagraphs (i)-(v) with
      respect to the later of his Termination of Service as an Employee or, if
      such Employee is also a Director, his Termination of Service as a
      Director.  Options granted by reason of the Optionee's status as a
      Director shall be exercisable in accordance with the foregoing provisions
      of subparagraphs (i)-(v) only with respect to his Termination of Service
      as a Director.  If an Incentive Stock Option is exercised after the
      expiration of the post-termination exercise periods that apply for
      purposes of Section 422 of the Code, such Incentive Stock Option will
      thereafter be treated as a Non-Qualified Stock Option.

            (F)   MINIMUM HOLDING PERIOD.  No Option may be exercised before
      the date which is six months after the date on which such Option was
      awarded.

            (G)   ADDITIONAL RESTRICTIONS RELATING TO INCENTIVE STOCK OPTIONS.
      To the extent that the aggregate Fair Market Value (determined as of the
      time the Option is awarded) of the Shares for which Incentive Stock
      Options are exercisable for the first time by the Optionee during any
      calendar year (under the Plan, any Prior Plans, or any other plan of the
      Company or a Subsidiary) exceeds $100,000 (or such other individual limit
      as may be in effect with regard to incentive stock options under the Code
      on the date of award), such Options shall not be Incentive Stock Options.
      No Incentive Stock Option shall be awarded to a Director or to an
      Optionee who, at the time such Option is awarded, owns stock possessing
      more than 10% of the total combined voting power of all classes of stock
      of the Company or any Subsidiary within the meaning of Section 422(b)(6)
      of the Code unless (i) at the time the Option is awarded, the Option
      Price is at least 110% of the Fair Market Value of the Shares subject to
      the Option, and (ii) such Option by its terms is not exercisable after
      the expiration of five years from the date such Option is awarded.

            (H)   LIMITATION ON OPTION AWARDS.  No Optionee may be awarded
      Options under the Plan in any calendar year with respect to more than
      500,000 Shares.

      SECTION 6.4. TERMINATION OR LAPSE OF OPTIONS.  Each Option shall
terminate or lapse upon the first to occur of (a) the expiration date set
forth in the applicable Option Agreement, (b) the date on which the Option is
deemed to be forfeited or terminated under the terms of the Plan or the Option
Agreement, (c) the applicable date set forth in Section 6.3(b), or (d) the date
which is the day next following the last day such Option could be exercised
under Section 6.3(e).

      SECTION 7.  EXERCISE AND PAYMENT OF OPTION PRICE.

      SECTION 7.1. EXERCISE OF OPTIONS.  Each Option shall be exercised as to

all or a portion of the Shares subject to the Option by written notice to the
Company setting forth the exact number of Shares as to which the Option is
being exercised and including with such notice payment of the Option Price
(plus the minimum required tax withholding).  The date of exercise shall be the
date such written notice and payment have been delivered (in cash or in such
other manner as provided in Section 7.2) to the Secretary of the Company either
in person or by depositing said notice and payment in the United States mail,
postage pre-paid and addressed to such officer at the Company's principal
office.
                                        A-8
      SECTION 7.2. PAYMENT FOR SHARES.  Payment of the Option Price (plus
required tax withholding) attributable to the exercise of an Option or any
portion thereof may be made (a) by tendering cash (in the form of a check or
otherwise) in such amount, (b) with the consent of the Committee, by tendering,
by either actual delivery of Shares owned by the Optionee or by attestation,
Shares with a Fair Market Value on the date of exercise equal to such amount,
(c) with the consent of the Committee, by instructing the Committee to withhold
a number of Shares having a Fair Market Value on the date of exercise equal to
the aggregate exercise price of such Option, (d) by delivering a properly
executed exercise notice together with irrevocable instructions to a broker to
promptly deliver to the Company the sale or loan proceeds equal to such amount,
or (e) any combination of (a), (b), (c), and (d); provided, however, that any
Shares delivered in payment of the Option Price pursuant to clause (b) shall
have been purchased on the open market and held by the Optionee for at least
six months at the time of exercise of the Option.

      SECTION 7.3. ISSUANCE OF SHARES.  No certificates representing Shares
shall be issued until full payment therefor has been made.  An Optionee shall
have all of the rights of a shareholder of the Company holding the Common Stock
that is subject to such Option (including, if applicable, the right to vote the
Shares and the right to receive dividends) when the Optionee has given written
notice of exercise, has paid in full for such Shares, has, if requested, given
the representation described in Section 16, and a certificate representing the
Shares have been issued by the registrar and transfer agent for the Common
Stock.

      SECTION 8.  AWARDING OF RESTRICTED STOCK.

      SECTION 8.1. AWARDS BY COMMITTEE.  Restricted Stock shall be awarded to
such eligible individuals, as determined by the provisions of Section 5, as the
Committee may, from time to time and at any time, select.  Membership of an
employee or a prospective employee in a class of management, administrative, or
professional employees or election as a Director shall not, without specific
Committee action, entitle such person to receive an award of Restricted Stock.

      SECTION 8.2. GRANT AGREEMENT.  Each award of Restricted Stock shall be
evidenced by a Grant Agreement, the terms of which may differ from other Grant
Agreements.  Each Grant Agreement shall be signed on behalf of the Company and
the Grantee, and shall set forth with respect to the Restricted Stock awarded
therein, the name of the Grantee, the date awarded, the number of Shares
subject to the Grant Agreement, and such other terms and conditions of vesting
consistent with the Plan as determined by the Committee.  Each Grant Agreement
shall be entered into subject to, and shall incorporate by reference, all
terms, conditions, and limitations set forth in the Plan.  For purposes of
Section 8.3(e), Shares which are the subject of an award of Restricted Stock
shall remain subject to the Grant Agreement which evidenced such award until
the Vesting Period shall have been completed with respect to such Shares.

      SECTION 8.3. TERMS AND CONDITIONS OF GRANTS OF RESTRICTED STOCK.  In
addition to any other terms, conditions, and limitations specified in the Plan,
each award of Restricted Stock hereunder shall, as to each Grantee, satisfy the
following requirements:

            (A)   DATE OF AWARD.  Restricted Stock must be awarded on or before
      June 21, 2010.

            (B)   VESTING AND OTHER TERMS AND CONDITIONS.  The Committee may at
      the time of award impose such terms and conditions on the vesting of the
      Restricted Stock subject to an award as it deems necessary or desirable
      for such award (i) to fulfill the purpose of this Plan, including the
      requirement that settlement of a Grant be conditioned upon achievement of
      Performance Goals or the continued service of the Grantee either before
      or after, as applicable, the achievement of Performance Goals, and (ii)
      to be exempt under Section 16(b) of the Exchange Act, and the regulations
      promulgated thereunder, or (iii) to qualify as a Qualified Performance-
      Based Grant.

            (C)   RECORDS OF RESTRICTED STOCK.  Shares of Restricted Stock
      shall be evidenced in such manner as the Committee may deem appropriate,
      including book-entry registration or issuance of one or more stock
      certificates.  Any certificate issued in respect of shares of Restricted
      Stock shall be registered
                                        A-9
      in the name of the Grantee and shall bear an appropriate legend
      referring to the terms, conditions, and restrictions applicable to such
      award, substantially in the following form:

            "The transferability of this certificate and the shares of stock
            represented hereby are subject to the terms and conditions
            (including forfeiture) of the Wausau-Mosinee Paper Corporation 2000
            Incentive Stock Plan and a Restricted Stock Agreement.  Copies of
            such Plan and Agreement are on file with the Secretary of the
            Corporation."

      The Committee may require that the certificates evidencing such Shares be
      held in custody by the Company until the restrictions thereon shall have
      lapsed and that, as a condition of any award of Restricted Stock, the
      Grantee shall have delivered a stock power, endorsed in blank, relating
      to the Common Stock covered by such award.

            (D)   LIMITATIONS ON TRANSFERABILITY.  Subject to the provisions of
      the Plan and the Restricted Stock Agreement, during the period which
      commences with the date of an award, and which ends on the expiration of
      the Vesting Period, the Grantee shall not be permitted to sell, assign,
      transfer, pledge or otherwise encumber shares of Restricted Stock.

            (E)   FORFEITURE OR VESTING UPON THE OCCURRENCE OF CERTAIN EVENTS.
      Except to the extent otherwise provided in the applicable Grant
      Agreement, upon a Grantee's Termination of Service for any reason during
      the Vesting Period, all shares of Restricted Stock still subject to
      restriction shall be forfeited by the Grantee; provided, however, that
      (i) all Restricted Stock shall become fully vested upon the death,
      Disability, or Retirement of the Grantee, if such Grant was not intended
      to be a Qualified Performance-Based Grant, (ii) all Restricted Stock

      shall become fully vested upon the death or Disability of the Grantee, if
      such Grant were intended to be a Qualified Performance Based Grant, and
      (iii) that all Shares subject to a Grant Agreement shall be forfeited if
      the Grantee incurs a Termination of Employment for Cause.

            (F)   LIMITATION ON GRANTS.  No Qualified Performance-Based Grant
      in excess of 100,000 shares of Restricted Stock shall be awarded to any
      Grantee in any calendar year.

      SECTION 8.4. RIGHTS OF SHAREHOLDER.  Except as provided in Section 8.3,
this Section 8.4, and the Grant Agreement, a Grantee shall have, with respect
to the shares of Restricted Stock, all of the rights of a shareholder of the
Company holding the Common Stock that is the subject of a Grant Agreement,
including the right to vote the Shares and the right to receive any cash
dividends.  If so determined by the Committee, (a) cash dividends on the Common
Stock that is the subject of the Grant Agreement shall be automatically
deferred and held, without interest, subject to the vesting of the underlying
Restricted Stock, (b) cash dividends on the Common Stock that is the subject of
the Grant Agreement shall be automatically deferred and reinvested in
additional Restricted Stock, held subject to the vesting of the underlying
Restricted Stock, or held subject to meeting performance goals or vesting
applicable only to dividends, or (c) dividends payable in Common Stock shall be
paid in the form of Restricted Stock, held subject to the vesting of the
underlying Restricted Stock, or held subject to meeting Performance Goals
applicable only to dividends; provided, however, that reinvestment of dividends
in additional Restricted Stock at the time of any dividend payment shall occur
only if sufficient Shares are then available under Section 3 after taking into
account all then outstanding Grants.

      SECTION 8.5. ISSUANCE OF SHARES.  No certificates representing
unrestricted Shares shall be issued to a Grantee nor will the restrictions
imposed pursuant to this Section 8 lapse until adequate provision for the
payment of the Grantee's income tax withholding has been made by such Grantee
or until the adjustment in the number of Shares provided for in Section 11 has
been made.  If and when the Vesting Period expires without a prior forfeiture
of the Restricted Stock, subject to the satisfaction of the Grantee's
obligations under the Restricted Stock Agreement, certificates without the
restrictive legend provided for in Section 8.3(c) shall be delivered to the
Grantee upon surrender of the certificates issued as of the date of the award
and bearing the legend provided for by Section 8.3(c).
                                        A-10
      SECTION 8.6. WAIVER OF SECTION 83(B) ELECTION.  Unless otherwise provided
by the Committee, as a condition of receiving a Grant of Restricted Stock, a
Grantee shall waive the right to make an election under Section 83(b) of the
Code to report the value of the Grant as income on the Date of Grant.

      SECTION 9.  AWARDING OF PERFORMANCE UNITS.

      SECTION 9.1. AWARDS BY COMMITTEE.  Performance Units shall be awarded to
such eligible individuals, as determined by the provisions of Section 5, as the
Committee may, from time to time, select.  Membership of an employee or a
prospective employee in a class of management, administrative, or professional
employees or election as a Director shall not, without specific Committee
action, entitle such person to receive an award of Performance Units.

      SECTION 9.2. GRANT AGREEMENT.  Each award of Performance Units shall be

evidenced by a Grant Agreement, the terms of which may differ from other Grant
Agreements.  Each Grant Agreement shall be signed on behalf of the Company and
the Grantee, and shall set forth with respect to the Performance Units awarded
therein, the name of the Grantee, the date awarded, the number of Performance
Units, and such other terms and conditions consistent with the Plan as
determined by the Committee.  Each Grant Agreement shall be entered into
subject to, and shall incorporate by reference, all terms, conditions, and
limitations set forth in the Plan.

      SECTION 9.3. TERMS AND CONDITIONS OF GRANTS OF PERFORMANCE UNITS.  In
addition to any other terms, conditions, and limitations specified in the Plan,
each award of Performance Units hereunder shall, as to each Grantee, satisfy
the following requirements:

            (A)   DATE OF AWARD.  Performance Units must be awarded on or
      before June 21, 2010.

            (B)   VESTING AND OTHER TERMS AND CONDITIONS.  The Committee may at
      the time of award impose such terms and conditions on the vesting of the
      Performance Units subject to an award as it deems necessary or desirable
      for such award (i) to fulfill the purpose of this Plan, including the
      requirement that settlement of a Grant be conditioned upon achievement of
      Performance Goals or the continued service of the Grantee either before
      or after, as applicable, the achievement of Performance Goals, (ii) to be
      exempt under Section 16(b) of the Exchange Act, and the regulations
      promulgated thereunder, or (iii) to qualify as Qualified Performance-
      Based Grants.

            (C)   LIMITATIONS ON TRANSFERABILITY.  Subject to the provisions of
      the Plan and the Grant Agreement, during the period which commences with
      the date of an award, and which ends on the expiration of the Vesting
      Period, the Grantee shall not be permitted to sell, assign, transfer,
      pledge or otherwise encumber the Performance Units subject to such
      agreement.

            (D)   FORFEITURE OR VESTING UPON THE OCCURRENCE OF CERTAIN EVENTS.
      Except to the extent otherwise provided in the applicable Grant
      Agreement, upon a Grantee's Termination of Service for any reason during
      the Vesting Period, all Performance Units not yet vested shall be
      forfeited by the Grantee; provided, however, that (i) all Performance
      Units shall become fully vested upon the death, Disability, or Retirement
      of the Grantee, if such Grant was not intended to be a Qualified
      Performance-Based Grant, (ii) all such Performance Units shall become
      fully vested upon the death or Disability of the Grantee, if such Grant
      was intended to be a Qualified Performance-Based Grant, and (iii) that
      all Performance Units shall be forfeited if the Grantee incurs a
      Termination of Employment for Cause.

            (E)   LIMITATION ON GRANTS.  No Qualified Performance-Based Grant
      in excess of 100,000 Performance Units (each such Unit attributable to
      one share of Common Stock) shall be awarded to any Grantee in any
      calendar year.

      SECTION 9.4. DEFERRAL OF RECEIPT.  A Grantee may elect to further defer
receipt of cash or shares of Common Stock in settlement of Performance Units
for a specified period, subject in each case to the Committee's approval and to

such terms as are determined by the Committee.  Subject to any exceptions
adopted by the

                                       A-11
Committee, such election must generally be made prior to commencement of the
Vesting Period for the Performance Units to which such election relates.

      SECTION 9.5. SETTLEMENT OF GRANTS.  In addition to any other terms and
conditions of a Grant which may be provided for under the Plan, the Committee
shall, at the end of each applicable Vesting Period, determine the number of
Performance Units which have become vested upon satisfaction of the applicable
Performance Goals, conditions of continued employment, or other conditions, and
shall then provide that such Performance Units shall be settled by delivery of
(i) shares of Common Stock equal to the number of Performance Units vested,
(ii) cash equal to the Fair Market Value of such number of shares of Common
Stock attributable to the number of Performance Units vested, or (iii) any
combination thereof as the Committee deems appropriate, subject to any deferral
election made by the Grantee pursuant to Section 9.4.

      SECTION 9.6. ISSUANCE OF SHARES.  No certificates representing
unrestricted Shares shall be issued to a Grantee until adequate provision for
the payment of the Grantee's income tax withholding has been made by such
Grantee or until the adjustment in the number of Shares provided for in Section
11 has been made.  If and when the Vesting Period expires without a prior
forfeiture of the Performance Units, subject to the satisfaction of the
Grantee's obligations under the Performance Unit Agreement, certificates
representing Shares to be delivered pursuant to Section 9.5 shall be delivered
to the Grantee.

      SECTION 10. DIVIDEND EQUIVALENT PAYMENTS.  The Committee may award
Dividend Equivalents with respect to some or all of the shares of Common Stock
covered by Performance Units in an amount equal to, and commensurate with,
dividends declared by the Board and paid on Common Stock.  Dividend Equivalents
payable on Performance Units may be paid in cash, Restricted Stock, or in
Common Stock at the discretion of the Committee.  The Committee may award
Dividend Equivalents with respect to any Performance Unit for all or any
portion of its term and may condition such award on the satisfaction of
Performance Goals.

      SECTION 11. TAX WITHHOLDING.  The delivery of Shares to a Grantee or any
other person under the Plan is subject to withholding of all applicable taxes,
and the Committee may condition the delivery of any Shares or other benefits on
satisfaction of applicable withholding obligations.  The Company may withhold
from the settlement of any award of Performance Units in cash the applicable
amount of withholding taxes.  Otherwise, the Grantee must satisfy all
applicable federal, state and local income tax withholding requirements by
delivering to the Company at the time of the exercise of an Option or the lapse
or satisfaction of any condition to vesting of Performance Units or Restricted
Stock, as the case may be, such amount of money, with the consent of the
Committee, Shares having a Fair Market Value equal to the amount determined by
the Company as required to meet its withholding obligation under applicable tax
laws or regulations, or, with the consent of the Committee, may direct the
Company to withhold from any certificate for Shares then or thereafter issuable
to the Grantee, that number of Shares having a Fair Market Value equal to any
tax required to be withheld by reason of such exercise or vesting.

      SECTION 12. CHANGE IN CONTROL.

      SECTION 12.1. ADJUSTMENT OF OPTIONS.

            (A)   VESTING AND CASH PAYMENT.  In the event of a Change in
      Control,

                  (i)   all Options outstanding on the date on which such
            Change in Control has occurred (the "Change in Control Date") (A)
            shall, to the extent not then exercisable or vested, immediately
            become exercisable in full and all conditions relating to the
            vesting of Restricted Stock shall be deemed to have been satisfied
            on the Change in Control Date, and (B) each Optionee may elect (the
            Optionee's "Election Right") with respect to each Option held by
            such Optionee on the Change in Control Date to surrender such
            Option for an immediate lump sum cash payment in an amount equal to
            the product of (A) the number of Shares then subject to the Option
            as to which the election is being exercised multiplied by (B) the
            excess, if any, of (1) the greater of (a) the Change in Control
            Price or (b) the highest Fair Market Value of a Share on any
                                        A-12
            day in the 60-day period ending on the Change in Control Date, over
            (2) the Option Price of such Option.  For purposes of this Section
            12.1(a), the "Change in Control Price" shall mean, if the Change in
            Control is the result of a tender or exchange offer or a Corporate
            Transaction (as defined in Section 12.2(c)), the highest price per
            Share paid in such tender or exchange offer or Corporate
            Transaction, and, to the extent that the consideration paid in any
            such transaction consists all or in part of securities or other
            noncash consideration, the value of such securities or other
            noncash consideration shall be determined in the sole discretion of
            the Committee;

                  (ii)  The restrictions and deferral limitations applicable to
            any Restricted Stock shall lapse, and such Restricted Stock shall
            become free of all restrictions and become fully vested and
            transferable to the full extent of the original Grant;

                  (iii) All Performance Units and Dividend Equivalents shall be
            considered to be earned and payable in full, and any deferral or
            other restriction shall lapse and such Performance Units shall be
            settled in cash as promptly as is practicable; and

                  (iv)  The Committee may also make additional adjustments
            and/or settlements of outstanding Grants as it deems appropriate
            and consistent with the Plan's purpose.

            (B)   ELECTION.  The exercise of an Election Right must be in
      writing, specify the Option or Options and the number of Shares as to
      which the election is being exercised, and be delivered to the Secretary
      of the Company either in person or by depositing said notice and payment
      in the United States mail, postage pre-paid and addressed to such officer
      at the Company's home office on or before the 60th day following the
      Change in Control Date.

            (C)   PAYMENT DATE.  All payments due an Optionee pursuant to the

      provisions of this Section 12.1 shall be made by the Company on or before
      the 5th business day following the date on which the Optionee's election
      has been delivered to the Company pursuant to Section 12.1(b).

      SECTION 12.2. DEFINITION OF "CHANGE IN CONTROL".  For purposes of the
Plan, a "Change in Control" means the happening of any of the following events:

            (a)   The acquisition by any individual, entity, or group (within
      the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act) (a
      "Person") of beneficial ownership (within the meaning of Rule 13d-3
      promulgated under the Exchange Act) of 20% or more of either (i) the then
      outstanding shares of common stock of the Corporation (the "Outstanding
      Corporation Common Stock") or (ii) the combined voting power of the then
      outstanding voting securities of the Corporation entitled to vote
      generally in the election of directors (the "Outstanding Corporation
      Voting Securities"); excluding, however, the following: (A) any
      acquisition directly from the Corporation other than an acquisition by
      virtue of the exercise of a conversion privilege unless the security
      being so converted was itself acquired directly from the Corporation, (B)
      any acquisition by the Corporation, (C) any acquisition by any employee
      benefit plan (or related trust) sponsored or maintained by the
      Corporation or any entity controlled by the Corporation, (D) any
      acquisition pursuant to a transaction which complies with clauses (i),
      (ii), and (iii) of paragraph (c) of this Section 12.2, (E) except as
      provided in paragraphs (d) and (e), any acquisition by any of the Woodson
      Entities or any of the Smith Entities, or (F) any increase in the
      proportionate number of shares of Outstanding Corporation Common Stock or
      Outstanding Corporation 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
      Corporation Common Stock or Outstanding Corporation Voting Securities by
      the Corporation; provided, however, that this clause (F) shall not apply
      to any acquisition of Outstanding Corporation Common Stock or Outstanding
      Corporation Voting Securities not described in clauses (A), (B), (C),
      (D), or (E) of this paragraph (a) by the Person acquiring such shares
      which occurs after such Person had become the beneficial owner of 20% or
      more of either the Outstanding Corporation Common Stock or Outstanding
      Corporation Voting Securities by reason of share purchases by the
      Corporation; or
                                        A-13
            (b)   A change in the composition of the Board such that the
      individuals who, as of the Effective Date, constitute the Board (such
      Board shall be hereinafter referred to as the "Incumbent 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

      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 contest (as such terms are used in Rule 14a-11 of Regulation 14A
      promulgated under the Exchange Act) or other actual or threatened
      solicitation of proxies or consents by or on behalf of a Person other
      than the Board shall not be so deemed or considered as a member of the
      Incumbent Board; or

      sale or other disposition of all or substantially all of the assets of
      the Corporation or the acquisition of the assets or securities of any
      other entity (a "Corporate Transaction"); excluding, however, such a

      the individuals and entities who are the beneficial owners, respectively,
      of the Outstanding Corporation Common Stock and Outstanding Corporation
      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 Corporation or
      all or substantially all of the Corporation's assets either directly or
      through one or more subsidiaries) (the "Resulting Corporation") in
      substantially the same proportions as their ownership, immediately prior
      to such Corporate Transaction, of the Outstanding Corporation Common
      Stock and Outstanding Corporation Voting Securities, as the case may be,
      (ii) no Person (other than the Corporation, any employee benefit plan (or
      related trust) of the Corporation, any Woodson Entity, any Smith Entity,
      or such Resulting Corporation) will beneficially own, directly or
      indirectly, 20% or more of, respectively, the 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 Corporation prior
      to the Corporate Transaction, and (iii) 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

            (d)   the Woodson Entities acquire beneficial ownership of more
      than 35% of the Outstanding Corporation Common Stock or Outstanding
      Corporation Voting Securities or of the outstanding shares of common
      stock or 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 Resulting Corporation; or

            (e)   the Smith Entities acquire beneficial ownership of more than
      35% of the Outstanding Corporation Common Stock or Outstanding
      Corporation Voting Securities or of the outstanding shares of common
      stock or 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 Resulting Corporation; or

            (f)   The approval by the shareholders of the Corporation of a
      complete liquidation or dissolution of the Corporation.

      foregoing), any trust established by any of Aytchmonde P. Woodson, Leigh
      Yawkey Woodson, or Alice Richardson Yawkey, whether pursuant to last will
      or otherwise, any partnership, trust, or other entity established
      primarily for the benefit of, or any other Person the beneficial owners
      of which consist primarily of, any of the foregoing or any Affiliates or
      Associates of any of the foregoing or any charitable trust or foundation
      to which any of the foregoing transfers or may transfer securities of the
      Corporation (including any beneficiary or trustee, partner, manager, or
      director of any of the foregoing, or any other Person serving any such
      entity in a similar capacity).

      transfer securities of the Corporation (including any beneficiary or
      trustee, partner, manager, or director of any of the foregoing, or any
      other Person serving any such entity in a similar capacity).

      For purposes of this Section 12.2, the terms "Affiliate" and "Associate"

      General Rules and Regulations under the Exchange Act as in effect on the
      date of this Plan.

      SECTION 13. DELIVERY OF CERTIFICATES.  Notwithstanding any other

under the Plan prior to fulfillment of all of the following conditions:

            (a)   Listing or approval for listing upon notice of issuance of

            (b)   Any registration or other qualification of the Shares under
      any state or federal law or regulation, or the maintaining in effect of

to the contrary, the amendment and restatement as adopted December 19, 2003,
shall not be effective, and any Restricted Stock or Performance Units awarded

under the Plan shall be null and void, unless the adoption of the Plan is
approved at the meeting of the Company's shareholders next following the date
of such amendment and restatement by the majority of the shares entitled to
vote at such meeting, and, in the event such shareholder approval shall not be
given, the Plan as in effect prior to December 19, 2002, shall remain in full
force and effect.

      SECTION 15. AMENDMENT AND TERMINATION OF PLAN.

      SECTION 15.1. AMENDMENT OF PLAN.  The Committee may amend the Plan from
time to time and at any time; provided, however, that (a) except as
specifically provide herein, no amendment shall, in the absence of written
consent to the change by the affected Grantee, adversely affect such Grantee's
rights under any Grant which has been awarded prior to the amendment except to
the extent such amendment is, in the sole opinion of the
                                        A-15
Committee, required to comply with any stock exchange rules, accounting rules,
or laws applicable to the Company or the Plan, (b) no amendment with respect to
the maximum number of Shares which may be issued pursuant to Grants under the
Plan or to any individual in any calendar year made be made unless approved by
a majority of the Shares entitled to vote at a meeting of the shareholders if
such amendment would, in the absence of such approval and in the sole opinion
of the Committee, have an adverse effect on the Company under applicable tax or
securities laws or accounting rules, and (c) no amendment shall be made without
the approval of the Company's shareholders to the extent such approval is
required by applicable law or stock exchange rules.

      SECTION 15.2. TERMINATION OF PLAN.  The Plan shall terminate on the first
to occur of (a) June 21, 2010 or (b) the date specified by the Committee as the
effective date of Plan termination; provided, however, that the termination of
the Plan shall not limit or otherwise affect any Grants outstanding on the date
of termination.

      SECTION 16. INVESTMENT INTENT.  The Committee may require each Grantee or
other person purchasing or receiving Shares pursuant to the exercise of an
Option or the Grant of Performance Units or Restricted Stock, to represent to
and acknowledge that the Shares, if not registered by the Company under the
Securities Act of 1933 (the "1933 Act"), may not be freely transferable by the
holder after exercise of the Option or receipt of a Grant, that by acceptance
of an Option, Shares, Performance Units, Dividend Equivalents, or Restricted
Stock, that such Grantee or other person understands that the application of
the 1933 Act may restrict the transfer of such Shares, and that Shares which
are unregistered under the 1933 Act will be acquired for the account of the
Grantee or other person for investment only and not with a view to offer for
sale or for sale in connection with the distribution or transfer thereof.
Certificates issued by the Company and representing Shares acquired pursuant to
the exercise of an Option or Grant of Performance Units, Dividend Equivalents,
or Restricted Stock may include any legend or legends which the Company deems
appropriate to reflect any restrictions imposed under the 1933 Act.

      SECTION 17. AVAILABILITY OF INFORMATION.

      SECTION 17.1. REGISTERED SHARES.  If the Shares subject to a Grant have
been registered pursuant to the 1933 Act, the Company shall provide the Grantee
with such information as may be required under the applicable registration form
on which such Shares were registered.

      SECTION 17.2. UNREGISTERED SHARES.  If the Shares subject to a Grant are
not registered or to be registered under the 1933 Act, the Company shall
furnish each Grantee with (a) a copy of the Plan and the Company's most recent
annual report to its shareholders at the time the Grant Agreement is delivered
to the Grantee and (b) a copy of each subsequent annual report and proxy
statement, on or about the same date as such report shall be made available to
shareholders of the Company.  Whether or not the shares are, or are to be,
registered under the 1933 Act, the Company will furnish, upon written request
addressed to the Secretary of the Company, but at no charge to the Grantee or
any duly authorized representative of the Grantee, a copy of the Plan and
copies of all reports filed by the Company with the Securities and Exchange
Commission, including, but not limited to, the Company's annual reports on Form
10-K, its quarterly reports on Form 10-Q, its current reports on Form 8-K, and
its proxy statements.  Notwithstanding the foregoing provisions of this Section
17, the Company shall not be required to furnish any such report or statement
if a copy of such report is otherwise provided to the Grantee in connection
with another plan maintained by the Company or such Grantee's status as a
shareholder of the Company.

      SECTION 18. LIMITATION OF RIGHTS.

      SECTION 18.1. CONDITIONS OF SERVICE.  Neither the Plan nor any Grant
Agreement shall constitute a contract of employment and participation in or
eligibility for participation in the Plan shall not confer upon any employee
the right to be continued as an employee of the Company or any present or
future Subsidiary or as a Director.  The Company and each Subsidiary hereby
expressly reserve the right to terminate the employment of any employee, with
or without cause, as if the Plan and any Grants awarded pursuant to it were not
in effect.
                                        A-16
      SECTION 18.2. COMPANY ASSETS.  Neither the Grantee nor any other person
shall, by reason of receiving a Grant, acquire any right, title, or interest in
any assets of the Company or any Subsidiary by reason of such Grant or the
Plan.  To the extent the Grantee or any other person shall acquire a right to
receive payments from the Company pursuant to a Grant or the Plan, such right
shall be no greater than the right of any unsecured general creditor of the
Company.

      SECTION 19. COMPLIANCE WITH APPLICABLE LAWS.  Notwithstanding any
provision of this Plan to the contrary, if at any time the Company shall be
advised by its counsel that the exercise of any Option or the delivery of
Shares upon the exercise of an Option or Grant of Performance Units, Dividend
Equivalents, or Restricted Stock is required to be approved, listed,
registered, or qualified under any securities law, that certain actions must be
taken under the rules of any stock exchange or over-the-counter market, that
such exercise or delivery must be accompanied or preceded by a prospectus or
similar circular meeting the requirements of any applicable law, or that some
other action is required to be taken by the Company in compliance with
applicable law, the Company will use reasonable efforts to take all actions
required within a reasonable time, but exercise of the Options or delivery by
the Company of certificates for Shares may be deferred until the Company shall
be in compliance with all such requirements.

      SECTION 20. GOVERNING LAW.  The Plan, each Grant awarded hereunder and
the related Grant Agreement, and all determinations made and actions taken
pursuant thereto, to the extent not otherwise governed by the Code or the laws

of the United States, shall be governed by the internal laws of the State of
Wisconsin and construed in accordance therewith without giving effect to the
principles of conflicts of laws applied by any state.
