Dear Shareholder:

      You are cordially invited to attend our annual meeting of shareholders to
be held on April 21, 2005, at the Great Hall on ArtsBlock, Wausau, Wisconsin.

      The Board has nominated Gary W. Freels and Thomas J. Howatt for
reelection as Class III directors and Michael M. Knetter, Dean of the
University of Wisconsin School of Business, for election to a newly created
Class III directorship.  At the annual meeting you will also be asked to
approve a change in our corporate name to "Wausau Paper Corp."  The change in
our corporate name is intended to complete the process begun last September
when we began to operate under the name "Wausau Paper" as part of a broader
initiative to create a unified brand recognition across our three business
segments.  Our branding initiative has been well received in our markets and
the amendment will provide consistency between our legal and commercial names. 

      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,


                                     THOMAS J. HOWATT

                            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 2005 annual meeting of shareholders, including any
adjournment thereof.  The annual meeting will be held at 2:00 p.m. on April 21,
2005, at the Great Hall on ArtsBlock, 401 North Fourth 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 18, 2005, 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 51,695,251 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.  Shares for which a broker does not have the authority to

vote are recorded as a "broker non-vote" and may count as a vote against
certain proposals.  See "Quorum, Required Vote, and Related Matters."   

      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
three 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. 

      Change of Company Name to "Wausau Paper Corp."  Proposal No. 2 (see
"Proposal No. 2 - Approval of Name Change to "Wausau Paper Corp.") will be
approved if two-thirds of the shares of stock issued and outstanding on the
record date are voted at the annual meeting vote for approval.  Therefore,
shares not represented at the annual meeting, broker non-votes, and abstentions
will have the same effect as a vote cast against 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 "About Wausau Paper - Corporate Governance" on
the Company's website at www.wausaupaper.com.  The Board has determined that
all members of the Committee are independent directors under New York Stock
Exchange, Inc. ("NYSE") listing standards.  See "- Corporate Governance
Guidelines and Committees of the Board of Directors - Corporate Governance
Committee," page 5, for more information on the Committee.

      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
                                       2
individual's current and past business or professional affiliations and
experience, age, stock ownership, particular 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 our Corporate Governance 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 Guidelines (which are 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 number of directors will increase to eight effective with the
election of directors at the annual meeting.  As increased, the Board will be

divided into three classes consisting of three Class I and Class III directors,
and two Class II 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.  

      Upon recommendation of the Corporate Governance Committee, the Board has
nominated Gary W. Freels and Thomas J. Howatt for reelection, and Michael M.
Knetter for election, as Class III directors for terms of office which will
expire at the annual meeting of shareholders to be held in 2008.  Mr. Knetter
was recommended to the Committee by an executive officer of the Company other
than the CEO.  No third party was engaged by the Committee to assist it in its
search for nominee candidates.  In the event any nominee 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 THREE
NOMINEES FOR CLASS III 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

      Meetings of the Board.  The Board met six times in 2004.  Each of the
directors attended at least 75% of the total number of the meetings of the
Board and the committees on which they served during the last fiscal year.

      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, 2005, meeting, the non-management directors
selected Dennis J. Kuester to preside over their meetings.  Shareholders and
others may communicate directly with Mr. Kuester 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,
100 Paper Place, 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.  If a
communication does not involve an ordinary business matter and if a particular
director is named, the communication will be forwarded to that director.  If no
particular director is named, such communication will be forwarded to the
Chairman of the appropriate Board committee.  If a complaint or concern
involves accounting, internal accounting controls, or auditing matters, the
correspondence may be addressed to, and will be forwarded to the Chairman of
the Audit Committee.  Our website also describes
                                       4
the Audit Committee's concern or complaint procedures.  In order to expedite
a response, the non-management directors have instructed management to receive,
research, and respond, if appropriate, on behalf of the Company's
non-management  directors or a particular director, to any communication
regarding an ordinary business matter.

      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 2004.

CORPORATE GOVERNANCE GUIDELINES AND COMMITTEES OF THE BOARD OF DIRECTORS

      Available Corporate Governance Documents.  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 on our website.  See "About Wausau
Paper - Corporate Governance" at www.wausaupaper.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"), NYSE listing
standards, and other applicable regulations.  

      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.  The
Audit Committee charter was amended in 2004, primarily to reflect the Audit
Committee's role in overseeing the Company's responsibility to maintain an
appropriate and effective system of internal controls.  The amended charter is
included with this proxy statement as Appendix A.  

      Mr. Freels (Chairman), Mr. Alexander, Mr. Baur, and Mr. Kuester serve on
the Audit Committee.  The full Committee met nine times and there were six
meetings between management and the Chairman of the Committee in 2004.  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 equity-based 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. Freels, and Mr. Smith
serve as members of the Compensation Committee.  The Committee met four times
in 2004.

      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 
                                       5
(4) recommend to the Board director nominees for each committee.  Mr. Kuester
(Chairman), Mr. Baur, and Mr. Smith serve on the Corporate Governance
Committee.  The Committee met three times in 2004.

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 any compensation or benefits other than the
standard arrangements described above.

      The Company maintains a deferred compensation program under which
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 in connection with 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, 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 2004, Mr. Alexander, Mr. Baur, 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 have at least
five years of service at termination 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.  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.  During 2004 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 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
on our website.  See "About Wausau Paper - Corporate Governance" at
www.wausaupaper.com.
                                       6
      Each of the Company's non-management directors meet the categorical
standards adopted by the Board and none of our non-management directors receive
any compensation from the Company other than in his capacity as a director.

The Board has determined that five of our Board members have no material
relationship with the Company and satisfy the requirements for independence
under the NYSE listing standards (Mr. Baur, Mr. Alexander, Mr. Freels, Mr.
Kuester, and Mr. Smith).  Upon the election of Mr. Knetter at the annual
meeting, six of our eight directors, including Mr. Knetter, will satisfy these
independence criteria.

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 2004 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 Committee also met with the Company's general
legal counsel to review and discuss legal claims and contingencies.  

      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 2004 fiscal year prior to their issuance.  At
                                       8
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:

(bullet) 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?

(bullet) 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?

(bullet) 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 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, 2004, 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 2004 after review by the
Committee of appropriate
                                       9
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. Baur, the authority
to grant pre-approvals for services, other than internal control related
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, 2004.  Representatives of Deloitte will
be present at the annual meeting and will have an opportunity to make a
statement or respond to appropriate questions.

      The following table presents aggregate professional fees paid or accrued
during the 2004 and 2003 fiscal years in the categories specified.  All
services performed received pre-approval by the Audit Committee.

      (1)Audit fees consisted of audit work performed in the preparation of
         financial statements, as well as work generally only the independent
         auditor can reasonably be expected to provide, such as statutory
         audits, review of SEC filings, and the attestation of management's
         report on the internal control of financial reporting. 
      (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 2004 represent fees of $215,201 related to tax compliance
         (tax returns, refunds, and payment planning) and fees of $73,512 for

         benefits to the Company in excess of the fees paid.

(1)Includes compensation deferred by officers under 401(k) plan and Executive Officers' Deferred Compensation Plan.
(2)The value indicated in table is based on the closing price of the Company's stock attributable to the grants
of performance units or restricted stock as determined on the date of award (December 17, 2004, $16.96 per
share). Mr. Howatt's award includes 5,000 shares of restricted stock which will vest on December 17, 2005.
Dividends paid on the restricted stock are held in escrow and distributed in cash only upon vesting of the
underlying stock. Vesting of all performance units awarded in 2004 is subject to the satisfaction of Company
performance criteria in 2005, and service by the grantee through December 31, 2006. 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 price of the
Company's stock on such date. At December 31, 2004, the number of shares attributable to awards held by the
officers named in the table (including shares attributable to hypothetical dividends on performance units) and
the value of such shares based on the closing price of the Company's common stock at December 31, 2004 ($17.86)
were: Mr. Howatt, 13,852 shares, $247,397; Mr. Carlson, 4,290 shares, $76,619; Mr. Davis, 3,705 shares,$66,168; 
Mr. Doescher, 3,421 shares, $61,104; and Mr. Chiericozzi, 3,333 shares, $59,527. 
(3)Director's fees of $30,000, 401(k) contributions of $5,228, and credits of $17,346 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."
(4)One-half of the options granted in 2002 were subject to satisfaction of financial performance conditions by 
the Company in each of fiscal years 2003 and 2004. Mr. Chiericozzi received a grant for the 2004 fiscal year
following his employment in September, 2003. Because financial performance conditions were not satisfied in 
either year, all options have lapsed.
(5)Contributions of $5,228 under 401(k) plan and, with respect to Mr. Carlson, credits payable under the 
Company's flexible benefit plan of $1,742.
(6)Reimbursement for taxes under relocation policy.
(7)Includes, as reimbursement of moving expenses under relocation policy with respect to: Mr. Davis, $20,160; 
and Mr. Chiericozzi, $10,822 in 2004 and $24,764 in 2003.

*   All grants in 2004 were stock options.
(1) Determined pursuant to Black-Scholes option pricing model.  The material
    assumptions and adjustments incorporated into the Black-Scholes model in
    estimating the value of the options reflected in the above table include
    (a) an option term of 20 years; (b) risk-free rate of return (represented
    by the interest rate on long-term U.S. Treasury securities with maturity
    date corresponding to the term on the grant date); (c) volatility
    calculated using daily stock prices for the 36-month period prior to the
    grant date; (d) dividends representing the annualized dividend paid with
    respect to the underlying common stock; and (e) reductions to reflect the
    probability of a shortened term due to termination of employment prior to
    the option expiration date.  The particular assumptions used for each grant
    date are:
    
                     RISK-FREE                            ANNUAL REDUCTION FOR

    The actual value, if any, a grantee will realize upon exercise of an option
    will depend on the excess of the market value of the common stock over the
    exercise price on the date the option is exercised.  See "Report of the
    Compensation Committee."  
(2) Vesting is subject to satisfaction of financial performance conditions by
    the Company in fiscal 2005. 
(3) Vesting is subject to continued service through December 17, 2005.

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 2004, a discretionary additional credit of 5% 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, 2004, the

(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 except Mr. Chiericozzi 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 subject to certain limitations
provided for in the plan.  Distribution will be made pursuant to an installment
method of up to 120 months, or in a lump sum, as elected by the Participant.
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 incentive plans.  This report describes the policies of the
Compensation Committee as in effect for the 2004 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 36 companies which, in addition to the Company,
comprise the CoreData 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.  The Committee
reviews this limit and its application to the Company's compensation policies
as part of its compensation policy.

      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
                                       14
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 specified goals, including, among others, targeted returns on capital
employed and achievement of individual performance objectives related to the
achievement of targeted rates of return on approved capital projects, increases
in mill operating efficiencies, and reductions in targeted components of
working capital.  

      Criteria used in the assessment of Mr. Howatt's eligibility for incentive
compensation in 2004 based upon individual objectives included the achievement
of targeted revenues from new products, targeted rates of return on approved
capital projects, and increases in mill operating efficiencies.  The individual
performance objectives for executive officers other than the CEO vary by
individual job responsibilities.  They may include, for example, achievement of
targeted levels of certain 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 in operating cost containment.

      Stock Based Compensation.  Executive officers participate in equity-based
plans at various levels.  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 any new grant and published data concerning
equity ownership and grants for executives within the paper industry.  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 2004.  Each member of the Committee is an independent
director under NYSE listing standards and none is a former officer of the
Company.

       PROPOSAL NO. 2 - APPROVAL OF NAME CHANGE TO "WAUSAU PAPER CORP." 

PROPOSED AMENDMENT TO CHANGE THE COMPANY'S NAME TO "WAUSAU PAPER CORP."

      The Board has proposed an amendment to Article 1 of our restated articles
of incorporation to change the name of the Company to "Wausau Paper Corp." from
the present "Wausau-Mosinee Paper Corporation."  As amended, Article 1 would
read as follows:

                                   Article 1

 The name of the corporation shall be Wausau Paper Corp. (the "Corporation").


      In September 2004, we announced that the Company would begin to operate
under the name "Wausau Paper" as part of a broader initiative to create a
unified brand recognition across our three business segments.  As part of the
branding initiative, all of our products were aligned under the Wausau Paper
name and are now sold under the Wausau Paper label.  This change has allowed us
to create a consistent brand in each of our markets while implementing
corporate-wide marketing and cross-selling efforts. 

      At the time we announced the change in our commercial name, we indicated
that we would seek to change the legal name of the Company at the annual
meeting.  Accordingly, the Board has proposed and recommended that the
shareholders vote "FOR" the amendment of our restated articles of incorporation
to change the legal name of the Company to "Wausau Paper Corp." 

      If the amendment to our restated articles of incorporation is approved at
the annual meeting, we intend to make it effective by promptly filing the
amendment with the Wisconsin Department of Financial Institutions.  Our
trading symbol on the New York Stock Exchange was changed to "WPP" in September
and no further change in that symbol will be required as a result of the change
in our legal name. 

VOTE REQUIRED FOR APPROVAL OF THE AMENDMENT

      Approval of the amended plan requires the affirmative vote of two-thirds
of our shares which are issued and outstanding on the record date, February 18,
2005.  Shares not voted at the annual meeting, including broker non-votes and
abstentions, will have the effect of a vote against the proposed amendment.    

      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 AMENDMENT TO OUR
RESTATED ARTICLES OF INCORPORATION TO CHANGE OUR NAME TO "WAUSAU PAPER CORP."

                                 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 2006 must deliver the written proposal to the Secretary of the
Company at our office in Mosinee, Wisconsin:

           (bullet)not later than November 18, 2005, if the proposal is
                   submitted for inclusion in our proxy materials for the 2006
                   meeting pursuant to Rule 14a-8 under the Exchange Act; or

           (bullet)on or after January 21, 2006, and on or before February
                   20, 2006, 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 2006 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 2006 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 Paper, 100 Paper Place, 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.  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.

                                     By order of the Board of Directors

                                     SCOTT P. DOESCHER

                         AS AMENDED DECEMBER 17, 2004


1.    PURPOSE

      The Audit Committee is appointed by the Board to assist the Board in
monitoring (1) the integrity of the financial statements of the Company, (2)

proxy statement.

2.    COMMITTEE MEMBERSHIP

fewer than three members.  The members of the Committee shall meet the
independence and experience requirements of the New York Stock Exchange,
Section 10A(m)(3) of the Securities Exchange Act of 1934 (the "Exchange Act")

not less frequently than quarterly.  The Committee shall meet periodically with
management, the internal auditors and the independent auditor in separate
executive sessions.  The Committee may request any officer or employee of the
Company or the Company's outside counsel or independent auditor to attend a

independent auditor shall report directly to the Committee.  

      (b)   Approval of Services.  

            (1)    The Audit Committee shall pre-approve all auditing services,

      (including the fees and terms thereof) to be performed for the Company by
      its independent auditor, subject to the de minimus exceptions for non-
      audit services described in Section 10A(i)(1)(B) of the Exchange Act
      which are approved by the Committee prior to the completion of the audit.

            (2)    The Audit Committee may form and delegate authority to
      subcommittees consisting of one or more members when appropriate.  The
      authority to grant pre-approvals of audit and permitted non-audit
      services may be delegated to the chair of the Committee, or, in his
      absence, one other member,
                                       A-1
      provided that decisions of such subcommittee to grant preapprovals shall
      be presented to the full Committee at its next scheduled meeting.

      (c)   Retention of Advisors.  The Audit Committee shall have the
authority, to the extent it deems necessary or appropriate, to retain
independent legal, accounting or other advisors.  The Company shall provide for

compensation to the independent auditor for the purpose of rendering or issuing
an audit report and to any advisors employed by the Committee.

      In exercising its authority and fulfilling its responsibilities under
this Charter, the Audit Committee, shall take the following actions to the
extent it deems necessary or appropriate. 

      (a)   Financial Statement and Disclosure Matters.  

            (1)    Review and discuss with management and the independent
      auditor the annual audited financial statements, including disclosures
      made under "Management's Discussion and Analysis of Financial Conditions
      and Results of Operations," and recommend to the Board whether the
      audited financial statements should be included in the Company's Form 10-
      K. 

            (2)    Review and discuss with management and the independent
      auditor the Company's quarterly financial statements prior to the filing

      "Management's Discussion and Analysis of Financial Conditions and Results
      of Operations."

            (3)    Discuss with management and the independent auditor
      significant financial reporting issues and judgments regarding accounting
      principles and financial statement presentations made in connection with
      the preparation of the Company's financial statements, including any

      significant changes in the Company's selection or application of
      accounting principles.
            
            (4)    Review and discuss with management and the independent
      auditor any major issues as to the adequacy of the Company's internal
      controls, any special steps adopted in light of material control
      deficiencies, and the adequacy of disclosures about changes in internal
      control over financial reporting.
            
            (5)    Review and discuss with management (including the senior
      internal audit executive) and the independent auditor the Company's
      internal controls report and the independent auditor's attestation of the
      report prior to the filing of the Company's Form 10-K.
            
            (6)    Review and discuss quarterly reports from the independent
      auditors on:

                   (A)   All critical accounting policies and practices to be
            used.

                   (B)   All alternative treatments of financial information
            within generally accepted accounting principles that have been
            discussed with management, ramifications of the use of such
            alternative disclosures and treatments, and the treatment preferred
            by the independent auditor.

                   (C)   Other material written communications between the
            independent auditor and management, such as any management letter
            or schedule of unadjusted differences.  
                                       A-2
            (7)    Discuss with management the Company's earnings press
      releases, including the use of "pro forma" or "adjusted" non-GAAP
      information, as well as financial information and earnings guidance
      provided to analysts and rating agencies.  Such discussion may be done
      generally (consisting of discussing the types of information to be
      disclosed and the types of presentations to be made).  The committee is
      not required to discuss in advance each release or each instance in which
      earnings guidance may be provided.

            (8)    Discuss with management and the independent auditor the
      effect of regulatory and accounting initiatives as well as off-balance
      sheet structures on the Company's financial statements.

            (9)    Discuss with management the Company's major financial risk
      exposures and the steps management has taken to monitor and control such
      exposures, including the Company's risk assessment and risk management
      policies.

            (10)   Discuss with the independent auditor the matters required to
      be discussed by Statement on Auditing Standards No. 61 relating to the
      conduct of the audit, including any difficulties encountered in the
      course of the audit work, any restrictions on the scope of activities or
      access to requested information, and any significant disagreements with
      management.

            (11)   Review disclosures made to the Audit Committee by the
      Company's CEO and CFO during their certification process for the Form 10-
      K and Form 10-Q about any significant deficiencies in the design or
      operation of internal controls or material weaknesses therein and any
      fraud involving management or other employees who have a significant role
      in the Company's internal controls.

      (b)   Oversight of the Company's Relationship with the Independent
Auditor.  

            (1)    Review and evaluate the lead partner of the independent
      auditor team.

            (2)    Obtain and review a report from the independent auditor at
      least annually regarding (a) the independent auditor's internal quality-
      control procedures, (b) any material issues raised by the most recent
      internal quality-control review, or peer review, of the firm, or by any
      inquiry or investigation by governmental or professional authorities
      within the preceding five years respecting one or more independent audits
      carried out by the firm, (c) any steps taken to deal with any such
      issues, and (d) all relationships between the independent auditor and the
      Company.  Evaluate the qualifications, performance and independence of
      the independent auditor, including considering whether the auditor's
      quality controls are adequate and the provision of permitted non-audit
      services is compatible with maintaining the auditor's independence, and
      taking into account the opinions of management and internal auditors.
      The Audit Committee shall present its conclusions with respect to the
      independent auditor to the Board.

            (3)    Ensure the rotation of the audit partners as required by
      law.  Consider whether, in order to assure continuing auditor
      independence, it is appropriate to adopt a policy of rotating the
      independent auditing firm on a regular basis.

            (4)    Recommend to the Board policies for the Company's hiring of
      employees or former employees of the independent auditor who participated
      in any capacity in the audit of the Company.

            (5)    Discuss with the independent auditor material issues on
      which the national office of the independent auditor was consulted by the
      Company's audit team and matters of audit quality and consistency.

            (6)    Meet with the independent auditor prior to the audit to
      discuss the planning and staffing of the audit.
                                       A-3
      (c)   Oversight of the Company's Internal Audit Function.

            (1)    Review the appointment and replacement of the senior
      internal auditing executive.

            (2)    Review the significant reports to management prepared by the
      internal auditing department and management's responses.

            (3)    Discuss with the independent auditor and management the
      internal audit department responsibilities, budget and staffing and any
      recommended changes in the planned scope of the internal audit.

      (d)   Compliance Oversight Responsibilities.

            (1)    Obtain from the independent auditor assurance that Section
      10A(b) of the Exchange Act has not been implicated.

            (2)    Obtain reports from management, the Company's senior
      internal auditing executive and the independent auditor that the Company
      and its subsidiary/foreign affiliated entities are in conformity with
      applicable legal requirements.  Review reports and disclosures of insider
      and affiliated party transactions and the report of the Corporate
      Governance Committee concerning the Corporate Compliance Program.  Advise
      the Board with respect to the Company's policies and procedures regarding
      compliance with laws and regulations applicable to the Company's
      reporting and disclosure obligations under the Exchange Act and other
      matters within the scope of the Committee's authority and responsibility.

            (3)    Establish procedures for the receipt, retention and
      treatment of complaints received by the Company regarding accounting,
      internal accounting controls or auditing matters, and the confidential,
      anonymous submission by employees of concerns regarding questionable
      accounting or auditing matters.

            (4)    Discuss with management and the independent auditor any
      correspondence with regulators or governmental agencies and any published
      reports which raise material issues regarding the Company's financial
      statements or accounting policies.  

            (5)    Discuss with the Company's general counsel legal matters
      that may have a material impact on the financial statements or the
      Company's compliance policies and internal controls. 

6.    LIMITATION OF AUDIT COMMITTEE'S ROLE

      While the Audit Committee has the responsibilities and powers set forth
in this Charter, it is not the duty of the Audit Committee to plan or conduct
audits or to determine that the Company's financial statements and disclosures
are complete and accurate and are in accordance with generally accepted
accounting principles and applicable rules and regulations.  These are the
responsibilities of management and the independent auditor.
