 ITEM 1.  BUSINESS.

 GENERAL DEVELOPMENT OF BUSINESS

 The Company was incorporated in Wisconsin on June 1, 1899, under the
 name of Wausau Paper Mills Company ("Wausau").  On December 17, 1997,
 Wausau completed a merger with Mosinee Paper Corporation ("Mosinee") in
 which Mosinee became a wholly-owned subsidiary of Wausau.  Simultaneous
 with the consummation of the merger, Wausau changed its name to
 Wausau-Mosinee Paper Corporation (hereinafter referred to as the
 "Company").

<PAGE>
 The Company manufactures, converts, and sells paper.  The Company's
 principal office is located in Mosinee, Wisconsin.  At December 31,
 1998, the Company had approximately 3,400 employees at eleven
 facilities located in six states.

 On December 17, 1997, the Company adopted a fiscal year-end reporting
 period of December 31.  This change from the Company's August 31 fiscal
 year-end was effective on December 31, 1997.  The merger with Mosinee
 was accounted for as a pooling-of-interests and as a result, the
 financial statements for the two companies have been restated as
 indicated in the footnotes which accompany the financial statements.
 See Notes 1 and 2 of "Notes to Consolidated Financial Statements."

 This report contains certain of management's expectations and other
 forward-looking information regarding the Company.  While the Company
 believes that these forward-looking statements are based on reasonable
 assumptions, all such statements involve risks and uncertainties that
 could cause actual results to differ materially from those contemplated
 in this report.  The assumptions, risks and uncertainties relating to
 the forward-looking statements in this report include those described
 in this Form 10-K under the caption "Cautionary Statement Regarding
 Forward-looking Statements" and, from time-to-time, in the Company's
 other filings with the Securities and Exchange Commission.

 FINANCIAL INFORMATION ABOUT SEGMENTS

 Information relating to the Company's sales, a measure of operating
 profit or loss, and total assets by segment is set forth in Note 16 of
 "Notes to Consolidated Financial Statements."

 NARRATIVE DESCRIPTION OF BUSINESS

 The Company competes in different markets within the paper industry. 
 Each of its operating groups serves distinct market niches.  The
 various markets for the products of the Company are highly competitive,
 with competition based on service, quality and price.

 The Company's eleven operating facilities are organized into the three
 operating groups described below.

                                     -1-

   SPECIALTY PAPER GROUP

 The Specialty Paper Group combines the Company's Mosinee, Sorg,
 Rhinelander, and Otis facilities to produce a wide variety of technical
 specialty papers.  The Group is a leader in many of its markets,
 although market position varies by product.

 The Rhinelander and Otis mills together are one of the nation's largest
 manufacturers of supercalendered backing papers for pressure sensitive
 labeling applications.  These facilities, located at Rhinelander,
 Wisconsin, and Jay, Maine, also manufacture specialty paper for a broad
 range of food, medical, and industrial applications, including

     include Crown Vantage, Mead Paper, Munksjo, Kimberly Clark, Dexter,
     Fletcher, Monadnock, Riverside Paper Corp., Little Rapids Paper
     Company, and French Paper.

     PRINTING & WRITING GROUP

 The Printing & Writing Group produces three lines of paper products in
 five facilities.

 Under the "Wausau Papers" trademark, the Group manufactures a broad
 line of premium printing and writing papers, imaging papers, colored
 offset papers and board grades at its mills in Brokaw, Wisconsin, and
 Groveton, New Hampshire.  Over 60% of the fine printing and writing
 papers produced are colored papers.  The Group's fine printing and
 writing sales are estimated to be less than 3% of the total market.
 Papers sold under the Wausau Papers label include a wide range of
 virgin and recycled printing and writing papers, two-thirds of which
 are colored papers, including Astrobrights<reg-trade-mark>, a 25-year
 old national brand.  Products, markets and distribution methods and
 principal competitors for Wausau Papers can be summarized as follows:

     PRINCIPAL PRODUCTS
     Text and cover, index, tag and bristol, imaging, premium offset,
     and envelope papers.

     PRINCIPAL MARKETS & DISTRIBUTION METHODS
     More than 80% of the sales of printing and writing papers are sold
     in sheet form to paper distributors which serve commercial
     printers, in-plant print shops, quick printers, copy centers, and
     retail office supply and home office outlets.  The Group also
     markets to converters that serve the greeting card and announcement
     industry.

                                     -3-

     towels.

     PRINCIPAL MARKETS & DISTRIBUTION METHODS
     Sold almost exclusively through sanitary maintenance suppliers and
     paper distributors in the U.S. and several foreign countries for
     use in the following markets:  industrial and commercial washroom,
     educational institutions, and the healthcare, dairy, and automotive
     service industries.

     PRINCIPAL COMPETITION
     Competition comes from major integrated paper companies which
     service consumer and food service markets as well as the industrial
     and institutional markets concentrated on by Bay West.  Major
     competitors include Fort James Corporation, Georgia Pacific,
     Kimberly Clark, and Wisconsin Tissue Mills.

     EXPORT SALES

 In addition to the three operating groups, Wausau-Mosinee
 International, Inc. is the commissioned sales agent for the export
 sales of the Company.  Wausau-Mosinee International, Inc. has elected
 to be treated as a FSC for federal income tax purposes.  During 1998
 the Company terminated its regional sales office presence in Singapore.

     RAW MATERIALS

 Pulp is the basic raw material for paper production.  The Mosinee and
 Brokaw mills produce approximately 85% and 50%, respectively, of their
 own pulp needs.  Timber required for operation of the Company's pulp
 mills is readily available.  The balance of the Company's pulp needs
 (approximately 450,000 tons) is purchased on the open market,
 principally from pulp mills throughout the United States and Canada.
 From time to time, the Company may purchase pulp futures contracts as a
 hedge against significant future increases in the market price of pulp.

 Recycled, de-inked fiber with a high content of post-consumer waste is
 purchased from domestic suppliers as part of the fiber requirements for
 Printing & Writing's recycled products. Recycled fiber is in adequate
 supply and readily obtainable.
<PAGE>
 The Towel & Tissue Group produces principally all of its de-inked fiber
 needs from 100% post-consumer waste which is readily available from
 domestic suppliers.

 Various chemicals are used in the pulping and papermaking processes.
 These industrial chemicals are all available from a number of suppliers
 and are purchased at current market prices.

                                     -5-

     ENERGY

 The Company's paper mills require large amounts of electrical and steam
 energy which are adequately supplied by public utilities or generated
 at Company operated facilities.  The Company generates approximately
 25% of its electrical power needs from steam, fuel oil, coal, wood
 chips, fibercake, and natural gas powered generating facilities.  The
 Company generally purchases natural gas, coal, and fuel oil on a
 contract basis at prevailing market prices.  Wood chips and fibercake
 are byproducts of mill operations.  Some natural gas and fuel oil
 purchase contracts may provide for variable prices or contain caps on
 prices of natural gas to be delivered at future dates.  In addition,
 the Company continues to explore alternative power sources as an
 ongoing business process.

 In July 1996, the Company signed a natural gas transportation agreement
 with the Portland Natural Gas Transmission System (PNGTS).  Under the
 terms of the long-term agreement, PNGTS has constructed necessary gas
 supply and delivery equipment to the Groveton, New Hampshire mill
 thereby assuring natural gas delivery at market rates.  The Company is
 progressing on schedule to begin transportation of natural gas to the
 Groveton mill in the third quarter of 1999.  Capital improvements,
 which are estimated to cost approximately $1.5 million, will be made to
 the Groveton mill's power plant to permit natural gas use.  A reduction
 in the mill's energy costs is expected from the use of natural gas as
 an energy source instead of fuel oil.

     PATENTS AND TRADEMARKS

 The Company develops and files trademarks and patents, as appropriate.
 Trademarks include AstroBright<reg-trade-mark>, Ecosoft
 <reg-trade-mark>, Bay West<reg-trade-mark>, Dublsoft<reg-trade-mark>,
 and Wave 'N Dry<reg-trade-mark>, among others.  The Company considers
 its trademarks and patents, in the aggregate, to be material to its
 business, although the Company believes the loss of any one such mark
 or patent right would not have a material adverse effect on its
 business.  The Company does not own or hold material licenses,
 franchises or concessions.

     SEASONAL NATURE OF BUSINESS

 The markets for some of the grades of paper produced by the Company
 tend to be somewhat seasonal.  However, the marketing seasons for these
 grades are not necessarily the same.  Overall, the Company generally
 experiences lower sales in the fourth quarter, in comparison to the
 rest of the year, primarily due to downtime typically taken by its
<PAGE>
 converting customers during the holiday season and a general slowing of
 business activity for many industrial users of Company products at that
 time of year.

     WORKING CAPITAL

 As is customary in the paper industry, the Company carries adequate
 amounts of raw materials and finished goods inventory to facilitate the
 manufacture and rapid delivery of paper products to its customers.  The
 Company will occasionally carry higher than normal quantities of pulp
 in anticipation of rising pulp prices.

     MAJOR CUSTOMERS

 Two customers accounted for approximately 9.5% and 8.0%, respectively,
 of consolidated net sales during 1998.  The loss of either of these
 customers would have a material adverse effect on the Company's
 business, but the Company believes such effect would be of relatively
 short duration.

                                     -6-

     BACKLOG

 The Company's order backlog at December 31, 1998 approximated 30,000
 tons, or 2 weeks of operation.  The backlog on such date was 10% less
 than December 31, 1997.

 Backlog totals do not accurately represent the strength of the
 Company's business activity as a significant volume of orders are
 shipped out of inventory promptly upon order receipt.  This portion of
 the business is not reflected in the Company's backlog totals.  The
 entire backlog at December 31, 1998 is expected to be shipped during
 fiscal 1999.

     RESEARCH AND DEVELOPMENT

 Expenditures for product development were approximately $3,309,000 in
 1998, $1,577,000 in 1997 and $1,381,000 in 1996.

     ENVIRONMENT

 The Company has a strong commitment to protecting the environment.
 Like its competitors in the paper industry, the Company faces
 increasing capital investments and operating costs to comply with
 expanding and more stringent environmental regulations.  For example,
 $2.8 million was spent on an electrostatic precipitator for the #5
 boiler at the Mosinee mill in 1998 and $14 million to rebuild and
 expand the wastewater treatment plant at the Brokaw mill in 1997.  The
 Company estimates that its capital expenditures for environmental
 purposes will approximate $3.5 million in 1999.

 The United States Environmental Protection Agency (EPA) has promulgated
 rules under the Clean Water Act and the Clean Air Act which impose new
 air and water quality standards for pulp and paper mills (the "Cluster
 Rules").  The definitive Cluster Rules, promulgated in April 1998,
<PAGE>
 require compliance by April 15, 2001.  Another set of requirements in
 the Cluster Rules must be implemented by April 15, 2006.

 In response to these regulations, the Company has opted to adopt Total
 Chlorine Free (TCF) technology for the pulp bleaching operations at the
 Brokaw mill.  This TCF technology must be in place and functioning by
 April 15, 2001.  In 1988, the Company installed an oxygen
 delignification system which eliminated the use of elemental chlorine;
 however, chlorine compounds are used in other stages of the bleaching
 process at the Brokaw mill.  Compliance with a TCF requirement for the
 Brokaw mill will require an estimated capital expenditure of $8 to $12
 million.

 The Mosinee facility will be required to burn additional noncondensable
 gases and treat foul condensates to comply with the Cluster
 Rules.  The majority of the required changes must be satisfied by April
 15, 2001, while compliance with the balance of these new requirements
 must be attained by April 15, 2006.  The estimated capital expenditure
 to comply with the Cluster Rules at the Mosinee facility is $8 million.

 The costs for complying with the Cluster Rules will be spread over
 1999, 2000, and 2001.  Company-wide capital expenditures are estimated
 to be in the range of $16-$20 million.

 Compliance with the EPA's permitting process involves the consolidation
 of all Company air discharge permits and is expected to involve an
 additional $1 million in capital expenditures.  This cost is expected
 to be incurred in 1999 or 2000.  Boiler upgrades in 2002 at the
 Rhinelander and Mosinee facilities, required to comply with new
 environmental rules, are expected to result in capital expenditures of
 approximately $3 million, although the Wisconsin Paper

                                     -7-

 Council and certain Wisconsin utilities have challenged the
 implementation of the new rules.

 The Company believes that capital expenditures associated with
 compliance with the Cluster Rules and other environmental regulations
 will not have a material adverse effect on its competitive position,
 consolidated financial condition, liquidity, or results of operation.

     EMPLOYEES

 On March 19, 1998, the Company announced and began implementation of a
 workforce reduction program which was expected to reduce Company-wide
 employment by over 8% from then current levels.  Approximately 300
 positions had been eliminated through December 31, 1998, almost all of
 which were accomplished through early retirement incentives along with
 voluntary separation arrangements.  The Company anticipates an
 additional reduction of 100 positions in connection with the program
 during 1999.

 The Company had approximately 3,400 employees at the end of 1998.  Most
 hourly mill employees are covered under collective bargaining
 agreements.  There were no new labor agreements negotiated during 1998.
<PAGE>
 Current labor agreements expire in 1999 through 2001 at the various
 mill sites.  The Company expects that new multi-year contracts will be
 negotiated at prevailing industry rates.  The Company considers its
 relationship with its employees to be good.

 YEAR 2000

 The Company has implemented a Year 2000 plan designed to address
 potential Year 2000 problems.  The financial impact of making the
 required system modifications and replacements to remedy Year 2000
 issues prior to December 31, 1999, has not been and is not expected to
 be material to the Company's consolidated financial condition,
 liquidity, or results of operations.  The Company expects its Year 2000
 issues to be satisfactorily addressed on a timely basis.  However, due
 to the interdependent nature of computer systems, there can be no
 assurance that the systems of other entities on which the Company's
 systems rely will also be timely converted or that any such failure to
 convert by another entity would not have an adverse effect on the
 Company's systems.  See Item 7, "Management's Discussion and Analysis
 of Financial Condition and Results of Operations - Year 2000."

 CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

 This Form 10-K, each of the Company's annual reports to shareholders,
 Forms 10-K, 8-K, and 10-Q, proxy statements, prospectuses, and any
 other written or oral statement made by or on behalf of the Company
 subsequent to the filing of this Form 10-K may include one or more
 "forward-looking statements" within the meaning of sections 27A of the
 Securities Act of 1933 and 21E of the Securities Exchange Act of 1934
 as enacted in the Private Securities Litigation Reform Act of 1995
 (the "Reform Act").

                                     -9-

 Forward-looking statements of the Company may be identified by, among
 other things, expressions of the Company's or Company officers' beliefs
 or expectations that certain events may occur or are anticipated, and
 projections or statements of expectations with respect to (i) any
 aspects of the Company's business (including, but not limited to, net
<PAGE>
 income, the availability or price of raw materials, or customer demand
 for Company products), (ii) the Company's plans or intentions, (iii)
 the Company's stock performance, (iv) the industries within which the
 Company operates, (v) the economy, and (vi) any other expressions of
 similar import or covering other matters relating to the Company or its
 operations.  In making forward-looking statements within the meaning of
 the Reform Act, the Company undertakes no obligation to publicly update
 or revise any such statement.

 Forward-looking statements are not guarantees of performance.
 Forward-looking statements of the Company are based on information
 available to the Company as of the date of such statements and reflect
 the Company's expectations as of such date, but are subject to risks
 and uncertainties that may cause actual results to vary materially.
 Many of the factors that will determine these results are beyond the
 Company's ability to control or predict.  Shareholders and others are
 cautioned not to put undue reliance on any forward-looking statements.
 For those statements, the Company claims the protection of the
 safe harbor for forward-looking statements contained in the Reform Act.

 In addition to specific factors which may be described in connection
 with any of the Company's forward-looking statements, factors which
 could cause actual results to differ materially include, but are not
 limited to, the following:

     <circle> Increased competition from either domestic or foreign
              paper producers or providers of alternatives to the
              Company's products, including increases in competitive
              production capacity resulting in sales declines from
              reduced shipment volume and /or lower net selling prices
              in order to maintain shipment volume.

     <circle> Changes in customer demand for the Company's products due
              to overall economic activity affecting the rate of
              consumption of the Company's products, growth rates of the
              end markets for the Company's products, technological or
              consumer preference changes, or acceptance of the
              Company's products by the markets served by the Company.

     <circle> Changes in the price of raw materials, in particular,
              pulp, wastepaper and linerboard.  A substantial portion of
              the Company's raw materials, including approximately
              two-thirds of the Company's pulp needs, are purchased on
              the open market and price changes could have a significant
              impact on the Company's costs.  Fiber represents a
              substantial portion of the cost of making paper and
              significant price increases for fiber could materially
              affect the Company's financial condition.  Raw material
              prices will change based on supply and demand on a
              worldwide spectrum.  Pulp price changes can occur due to
              worldwide consumption levels of pulp, pulp capacity
              additions, expansions or curtailments of the supply of
              pulp, inventory building or depletion at pulp consumer
              levels which affect short-term demand, and pulp producer
              cost changes related to wood availability, environmental
              issues, or other variables.
<PAGE>
     <circle> Unforseen operational problems at any of the Company's
              facilities causing significant lost production and/or
              cost increases.

                                     -10-

     <circle> Significant changes to the Company's strategic plans such
              as a major acquisition or expansion, the failure to
              successfully execute major capital projects, or other
              strategic plans or to successfully integrate an
              acquisition.

     <circle> Unforseen business interruptions or operational failures
              as a result of unanticipated Year 2000 readiness problems
              encountered by the Company, its vendors, or customers.

     <circle> Changes in laws or regulations which affect the Company.
              The paper industry is subject to stringent environmental
              laws and regulations and any changes required to comply
              with such laws or regulations may increase the Company's
              capital expenditures and operating costs.

                                     -11-

 ITEM 3.  LEGAL PROCEEDINGS.

 In 1997, the Attorney General of the State of Florida filed a civil
 complaint in the United States District Court for the Northern District
 of Florida against ten manufacturers of commercial sanitary paper
 products, including the Company's wholly owned subsidiary, Bay West
 Paper Corporation.  The lawsuit alleges a conspiracy to fix prices of
 commercial sanitary paper products starting at least as early as 1993.
<PAGE>
 Since the filing of this lawsuit, numerous class action suits have been
 filed by private direct purchasers of commercial sanitary paper
 products in various federal district courts throughout the country and
 additional federal lawsuits have been filed by the Attorneys General of
 the States of Kansas, Maryland, New York, and West Virginia. All of
 these federal cases have been certified as class actions and
 consolidated in a multi-district litigation proceeding in the United
 States District Court for the Northern District of Florida in
 Gainesville.  Certain indirect purchasers of sanitary commercial paper
 products have also filed class action lawsuits in various state courts
 alleging a conspiracy to fix prices under state antitrust laws.  No
 class has been certified in the state actions.  All of these actions
 are in early stages.  In the opinion of management, the Company has not
 violated any antitrust laws. The Company is vigorously defending these
 claims.

 The Company is also involved from time to time in various other legal
 and administrative proceedings or subject to various claims in the
 normal course of its business. In the opinion of management, the
 ultimate disposition of these matters will not have a material adverse
 effect on the consolidated financial condition, liquidity, or results
 of operations of the Company.

 ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

 No matters were submitted to a vote of shareholders during the fourth
 quarter of 1998.

  For the twelve months ended December 31, 1998, net sales were a record
 $946.1 million, $13 million over 1997 net sales of $933.1 million.
 Total shipments of the Company's three operating groups (Printing &
 Writing, Specialty Paper, Towel & Tissue) were also a record 831,800
 tons in 1998, an increase of 4.2% from the 798,500 tons shipped in
 1997.  Shipments were 679,100 tons in 1996.   Revenue and shipment
 growth in 1998 and 1997 was aided by the acquisitions of B&J Supply
 and Otis Specialty Papers.  Selling prices for the Company's products
 declined in both 1998 and 1997 due to competitive pressures on several
 products in the Company's printing and writing, specialty, and towel
 and tissue grades.

 Shipments at the Printing & Writing Group were similar for 1998 and
 1997.  B&J Supply and the Converted Products facilities recorded
 increases in 1998 while the paper manufacturing facilities decreased
 approximately 4%.  A major portion of this decrease was a decision not
 to participate in certain commodity grades due to poor selling prices.
 Premium paper sales increased and enhanced overall product mix, 
 although, downward pressure on paper prices resulted in lower
 sales dollars for the group.  Overall group shipments were 13.8% higher
 in 1997 compared to 1996.  All operating facilities within the Group
 recorded gains in 1997 over 1996.  Continued mix improvement and volume
 gains will be a focus for 1999.

 Shipments were a record at the Specialty Paper Group for 1998.  Total
 tonnage of 367,700 increased 7% over 1997 tonnage of 344,600.  The major
 portion of the increase was attributable to the Otis facility, which
 was acquired in May of 1997.  Volume in 1997 was 23% greater than 1996
 with the major portion of that increase also attributable to the Otis
 acquisition.  Competitive market pressures in both 1998 and 1997
 resulted in lower selling prices on a year-over-year comparison. The
 Specialty Paper Group experienced softening in demand in both 1998 and
 1997, which resulted in limited downtime for both years. The focus for
 1999 will be to improve product mix in particular for the Sorg and Otis
 facilities where machine capabilities were or will be enhanced.

 The Towel & Tissue Group continued its record volume growth in 1998.
 Volume has increased 13%, 14%, and 14% for the last three years on a
 year-over-year comparison. This volume growth has principally been
 accomplished by increasing distributors and adding converting lines.
<PAGE>
 Average pricing declined 5% in 1998 over the prior year's average while
 1997 was slightly below 1996.

                                     -16-

 Order backlog at the end of 1998 approximated 30,000 tons for all
 operating groups and was 10% less than in 1997. In 1997 backlogs had
 increased 6% over 1996 principally due to acquisitions.  Order backlog
 totals do not necessarily indicate the business strength entirely since
 a substantial percentage of orders are shipped directly from inventory
 upon receipt.

</TABLE>

 Gross profit decreased to $175.1 million or 19% of net sales in 1998
 compared to a 1997 gross profit of $199.7 million or 21% of net sales.
 Gross profit was $183.3 million in 1996 or 21% of net sales. The
 negative impact of reduced selling prices principally caused the margin
 decline in 1998.  While selling prices declined in 1997, gross margins
 remained similar to 1996 due to offsetting lower raw material costs.

 Market prices for pulp, the primary raw material used in manufacturing
 paper, declined during 1998. In 1998, the average list price of
 northern bleached softwood kraft, a frequently-used benchmark pulp
 grade, decreased 20% from the 1997 level compared to an 18% and 8%
 decrease in 1997 and 1996, respectively.

 Wastepaper prices, the primary raw material used in the production of
 toweling and tissue, increased 6% in 1998 over 1997 average prices and
 had increased 10% in a comparison of 1997 to 1996.

 The Printing & Writing Group's mills operated near capacity in 1998 and
 total tons produced were similar for both 1998 and 1997.  Paper
 production increased 5% in 1997 and 3% in 1996 over the previous year.
 Increases were principally attributable to capital and operational
 improvements.  Other facilities within the group reported year-over
 -year increases for all years presented.  Inventory levels increased
 13% in 1998 due in part to stocking a new West Coast warehouse facility
 in late 1998.

 The Specialty Paper Group mills operated near capacity for all years
 presented. Softening demand and poor market conditions resulted in
 nominal downtime in both 1998 and 1997 at the Otis and Rhinelander
 facilities.  Overall production declined 5% in 1998 compared to 1997
 principally due to product mix. This product mix was offset somewhat
 due to the acquisition of the Otis facility. Production levels
 increased both for 1997 and 1996 on a previous year comparison. 
 Product mix, capital improvements, and the Otis acquisition all were
 factors contributing to the increases. Inventory levels declined
 approximately 10% in 1998.
<PAGE>
 Converting production at the Towel & Tissue group increased similarly
 to its sales volume growth for all years presented.  Inventory levels
 approximated 7,000 tons at the end of 1998 and increased 1,200 tons
 over 1997.

     LABOR

 A new five-year labor agreement with the United Paperworkers
 International Union at the Groveton mill was successfully negotiated in
 1997.  The new agreement became effective April 1, 1997 and included a
 general wage increase of 3.5% in 1997, 3.0% in both 1998 and 1999, 3.5%
 in 2000 and 3.0% in 2001.  A new four-year labor agreement was also
 successfully negotiated in 1997 with the United Paperworkers
 International Union at Sorg. The new agreement, which became effective
 November 1, 1997, includes a general wage increase of 2.5% in 1997,
 3.0% in both 1998 and 1999 and 2.5% in 2000.  Labor agreements in other
 facilities expire in 1999, 2000 and 2001.

 The Company maintains good labor relations in all facilities.

</TABLE>

 Selling, administrative and research expenses, excluding the merger and
 restructuring expenses discussed below were $60.1 million in 1998,
 compared to $65.3 million in 1997 and $64.2 million in 1996. During
 1998, decreases in the Company's stock price resulted in a net $1.5
 million credit for stock appreciation rights, dividend equivalent and
 stock option discount expense, compared to charges in 1997 and 1996 of
 $2.1 million and $5.0 million, respectively. General inflationary costs
 offset by fluctuations in incentive compensation and retirement plan
 costs along with the acquisitions of the Otis and B&J facilities
 accounted for a majority of the other changes.

 In connection with the merger with Mosinee Paper Corporation (Mosinee),
 the Company incurred pre-tax expenses related to the merger of $13.5
 million, which were charged to operations in 1997. The costs include
 professional fees and other transaction costs for executing the merger
 as well as the costs of the severance benefits paid to the former CEO
 of the Company.  The merger costs on an after-tax basis were $13.2
 million or $.23 per share.  Restructuring and further merger costs were
 recorded in 1998 of $42.8 million.  Approximately 95% of these costs
 were associated with the Company's early retirement incentives along
 with voluntary separation arrangements, involuntary severance
 agreements, and training costs for the Company's 1998 workforce
<PAGE>
 reduction program.  The balance of the restructuring costs were for
 legal, consulting, and other miscellaneous costs. The after-tax charge
 was $26.5 million or $.48 per share for 1998.

</TABLE>

 Interest expense amounted to $7.7 million in 1998, compared to $8.1
 million in 1997 and $7.2 million in 1996. Interest expense was lower in
 1998 principally due to lower interest rates and lower average debt
 levels.  Interest expense in 1997 increased over 1996 due primarily to
 higher debt levels associated with the acquisitions of the Otis and B&J
 Supply facilities.  Capitalized interest totaled $.7 million, $.5
 million and $1.1 million in 1998, 1997 and 1996, respectively.
 Fluctuations in capitalized interest are primarily dependent on varying
 levels of capital expenditures qualifying for capitalized interest
 criteria.

 Other income includes interest income of $.4 million, $.1 million and
 $.6 million in 1998, 1997 and 1996, respectively. The difference in
 other income and expense is primarily due to fluctuations in the gain
 or loss on asset sales and disposals.

 of 38%.  The effective tax rates for 1997 and 1996 were 42.4% and
 39.1%, respectively.  The increase in the 1997 tax rate was due
 principally to the $13.5 million charge for merger-related expenses,
 most of which was not tax deductible.

 Cash provided by operations was $117.9 million in 1998, an increase of
 18% from 1997 operating cash flow of $99.7 million. Cash provided by
 operations was $136.4 million in 1996.  The increase in 1998 was
 primarily due to a decrease in receivables, reduced changes for
 investments in inventories and other assets, along with increases in
 accounts payable and other liabilities, all offset by reduced net
 earnings.  The reduction in cash flow for 1997, compared to 1996, was
 due mainly to an increase in working capital needs associated with
 higher accounts receivable and a smaller increase in accounts payable
 and other liabilities.

 Capital expenditures were $77.0 million in 1998, compared to $66.1
 million in 1997 and $82.5 million in 1996.  The 17% increase in capital
 spending in 1998 was due to general upgrades of pulp mills and paper
 machines resulting from business expansion opportunities following the
 merger with Mosinee.

                                     -20-

 In 1998, the Printing & Writing Group completed several projects at the
 Groveton mill totaling $6.2 million. The projects consisted of paper
 machine upgrades and a stock blending system which provides better
 efficiency, faster and continuous furnish, less broke and a reduction
 in usage of higher cost fiber.  The Brokaw mill spent $6.1 million in
 1998 on an $8.8 million pulp mill distributive control system to
 improve pulp quality and reduce operating costs.  The Specialty Paper
 Group completed several major projects in its pulp and paper mills,
 including spending $2.1 million for rebuilds of the #1 paper machines
 at the Mosinee and Sorg mills, $2.1 million for a wet lap machine and
 $2.8 million on a boiler precipitator at the Mosinee mill. The Otis
 mill spent $5.4 million on a $25 million rebuild to its two paper
 machines.  The Towel & Tissue Group completed a building expansion
 project totaling $6 million to increase operating plant and warehouse
 space by 268,000 square feet, $2.6 million on additional towel and
<PAGE>
 tissue converting lines and $5.7 million to rebuild the #1 paper
 machine for added toweling production capacity to keep pace with
 increasing sales volume.

 The Board of Directors approved a number of major capital improvements
 in 1998, on which spending will continue into 1999.  A $25 million
 rebuild to the Otis mill's two paper machines was approved.  This
 project will expand the production capacity of the machines and add
 significant new manufacturing capabilities to give the Specialty Paper
 Group an improved sales mix.  Nearly $6 million was approved for the
 Towel & Tissue Group to add converting lines for expanding sales
 volume.  Other major capital improvement projects approved by the Board
 of Directors, include $3.6 million for a woodroom modernization and
 $3.7 million for a boiler precipitator at the Mosinee mill, $8.8
 million for an upgrade to the dry end of the paper machines at the
 Brokaw mill, to include winder, reels, repulper and automated guided
 vehicles for roll movement, and nearly $4 million at the Groveton mill
 for general upgrades and conversions.  At the end of 1998, the Company
 was committed to spend $70 million to complete these capital projects
 and others currently under construction.

 During 1998, the Company obtained two separate lines of credit which
 provided an additional $80 million of available funds to assist in the
 authorized repurchase of Company stock. At December 31, 1998, $39
 million was outstanding on these lines of credit.

 The Company maintains a revolving credit facility with four banks of
 $105 million. The agreement extends through March 29, 2001 at which
 time, or earlier at the Company's option, the agreement converts to a
 one-year term

                                     -21-

 loan. The Company also maintains a commercial paper placement
 agreement, with one of its four major banks, which provides for the
 issuance of up to $40 million of unsecured debt obligations.  The
 commercial paper placement agreement requires unused credit
 availability under the Company's revolving credit agreement equal to
 the amount of outstanding commercial paper.  On December 31, 1998, the
 Company had a combined total of $13.5 million available for borrowing
 under its revolving credit and commercial paper placement agreements.

 In August 1995, the Company obtained $19 million in industrial
 development bond financing to fund an upgrade of the Brokaw mill
<PAGE>
 wastewater treatment plant, the construction of a new landfill and
 several other projects which qualify for this type of financing.  Bond
 proceeds were fully disbursed as of January 1997.

 In September 1994, Mosinee entered into an unsecured five-year debt
 arrangement with one of its banks for $20 million at a fixed rate of
 7.83%.  This debt arrangement was maintained subsequent to the Mosinee
 merger.  Principal is due in September 1999.

 In June 1993, the Company borrowed $30 million through the issuance of
 notes to Prudential Insurance Company of America and its subsidiaries.
 Proceeds from the notes were used to reduce borrowings from the
 revolving credit facility.

 On August 31, 1998, the Company's Board of Directors authorized the
 repurchase of 5,650,000 shares of the Company's common stock.  The
 repurchases may be made from time to time in the open market or through
 privately negotiated transactions.

 The Company repurchased 4,285,900 shares of its common stock in 1998
 under the completed 1994 authorization and the 1998 authorization at
 market prices ranging from $12.125 to $18.00.  The Company did not
 repurchase any shares of the Company's stock in 1997. Prior to merging
 with the Company, Mosinee repurchased 478,807 shares of its common
 stock in 1997.  Based on the terms of the merger, 1.4 shares of the
 Company's common stock were exchanged for each Mosinee share.  The
 stock repurchases were the equivalent of 670,330 shares of the
 Company's common stock in 1997.  As of the merger date of December 17,
 1997, all Mosinee treasury stock was retired.

 During 1998, the Board of Directors declared cash dividends of $.28 per
 share, an increase of 12% from the $.25 per share cash dividend
 declared in 1997.

 The cash provided by operations, the revolving credit facility and the
 available lines of credit are expected to meet capital needs and
 dividend requirements.  The Company plans to refinance the outstanding
 debt obligations to secure longer term financing in 1999.

 YEAR 2000

 Year 2000 issues apply to the Company's computerized manufacturing
 process controllers, environmental systems, order processing, inventory
 management, the shipment of finished goods, and internal financial and
 other information systems.  Year 2000 issues also apply to the
 Company's suppliers and customers.  For purposes of this discussion,
 the terms "Year 2000 issues" or "Year 2000 problems", or terms of
 similar import, refer to the potential failure of

                                     -22-

 computer applications as a result of the failure of a program or
 hardware to properly recognize the year 2000 and to properly handle
 dates beyond the year 1999.  The term "Year 2000 readiness", or terms
 of similar import, mean that the particular equipment or processes
 referred to have been modified or replaced and the Company believes
<PAGE>
 that such modified or replaced equipment or processes will operate as
 designed after 1999 without Year 2000 problems.

     READINESS

 The Company has developed a Year 2000 Plan intended to (1) upgrade its
 information technology hardware and software and all software and
 embedded technology applications in its equipment and facilities to be
 Year 2000 ready, (2) assess the Year 2000 readiness of suppliers and
 customers, and (3) develop contingency plans, if practical, for
 critical systems and processes.

 The Company has completed an inventory of mission critical information
 systems, process equipment, and manufacturing facilities. The Company
 continues to evaluate and test equipment, environmental controls, and
 other core functions.  Assessment and testing is expected to be
 completed by May, 1999. The Company believes that the most critical
 information systems, primarily the sales order processing, inventory,
 and shipping systems, are already Year 2000 ready or, if not, that such
 systems have been given first priority to be made Year 2000 ready and
 will be ready by September, 1999.  The Company's enterprise resource
 planning system ("ERP") is intended to bring the remainder of the
 Company's information systems to Year 2000 readiness by September,
 1999.  The broader, non-Year 2000 aspects of the ERP system will be
 fully implemented in 2001.

     COSTS

 The costs of achieving Year 2000 readiness have not been material to
 date and are not expected to be material.  The cost of remediation for
 key papermaking process controls and equipment is expected to be less
 than $2 million.  Internal costs for Year 2000 readiness are not being
 tracked, but principally relate to payroll costs of Company personnel.
 The implementation of the Company-wide ERP system is expected to
 require a capital investment of approximately $5.5 million.  Although
 the ERP implementation timetable was not accelerated to address Year
 2000 issues, those issues were considered in determining the overall
 timetable for its implementation.

     RISKS

 The Company expects no material adverse effect on its consolidated
 financial condition, liquidity or results of operations (collectively,
 its "business") as a result of problems encountered in its own business
 as a result of Year 2000 issues or as a result of the impact of Year
 2000 problems on its customers or vendors.  However, the risks to the
 Company associated with Year 2000 issues are many.

 The Company's assessment of possible Year 2000 related problems
 depends, to some extent, on the assurances and guidance provided it by
 the suppliers of the technology as to its Year 2000 readiness.  In
 addition, the Company has limited ability to independently verify the
 possible effect of Year 2000 problems on its customers and vendors.  
 Therefore, the Company's assumptions

                                     -23-
<PAGE>
 concerning the effect of Year 2000 issues relies, in part, on its
 ability to analyze the business and operations of each of its critical
 vendors or customers.  This process is, by the nature of the problem,
 limited to such persons' public statements, their responses to the
 Company's inquiries, and the information available to the Company from
 third parties concerning the industries or particular vendors or
 customers involved.

 The Company expects that Year 2000 problems which cause customers to be
 unable to place orders would have a material adverse impact on its
 business only if the problem was widespread and long-lived.  The
 Company has a broad customer base, which would likely alleviate the
 adverse effects of isolated customer Year 2000 problems.

 Some risk also exists that, despite the Company's best efforts,
 critical manufacturing systems may malfunction due to Year 2000
 problems and curtail the manufacturing process.  The Company does not
 anticipate such interruptions and it is unlikely any such curtailment
 would be lengthy.  With eleven manufacturing facilities, a temporary
 interruption at one facility is unlikely to have a material adverse
 impact on the Company's business.

 Interruption of raw material supply due to supplier problems caused by
 Year 2000 issues are not expected to be material as the Company stocks
 raw materials to protect against supply problems and alternative
 sources of supply exist to meet the Company's raw material needs.
 Similarly, although the Company faces potential disruptions in its
 operations from Year 2000 problems as a result of the failure of the
 power grid, telecommunications, or other abilities, it is not aware
 that any material disruption in these infrastructures is reasonably
 likely to occur and the number and widespread location of its
 facilities is likely to minimize the impact of any disruption.

     CONTINGENCY PLAN

 The Company has evaluated various contingencies that may arise as a
 result of Year 2000 issues.  The Company anticipates that disruptions
 in production, sales, the supply of raw materials, loss of customer
 orders, and other foreseeable effects of the Year 2000 issues can be
 addressed following normal business alternatives.  The Company will
 continue to analyze and develop contingency plans where possible and
 not cost prohibitive.

 ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK.

 The company does not have a material market risk associated with
 interest rate risk, foreign currency exchange risk, or commodity price
 risk.  The company does not hold or engage in transactions involving
 derivative financial instruments.  The company conducts U.S. dollar
 denominated export transactions or immediately exchanges all foreign
 currency attributable to export sales for U.S. dollars.
<PAGE>
 The company maintains certain derivative commodity instruments as
 hedges for anticipated transactions.  Such instruments do not have a
 material market risk and no such derivative commodity instrument is
 held for trading.  At December 31, 1998, these instruments consisted of
 various futures contracts for the purchase of natural gas and fuel oil.
 From time to time, the company may also purchase pulp futures contracts
 as a hedge against pulp price increases.  See Notes 1 and 14 of "Notes
 to Consolidated Financial Statements" for additional information
 relating to the company's derivative commodity instruments.

 Wausau-Mosinee Paper Corporation
 Mosinee, Wisconsin

 We have audited the accompanying consolidated balance sheets of Wausau-

 stockholders' equity for the years ended December 31, 1998 and 1997 and
 August 31, 1996, and the supporting schedule of valuation and
 qualifying accounts.  These financial statements and supporting
 schedule are the responsibility of the company's management.  Our
 responsibility is to express an opinion on these financial statements
 and supporting schedule based on our audits.

 We conducted our audits in accordance with generally accepted auditing
 standards.  Those standards require that we plan and perform the audit
 to obtain reasonable assurance about whether the financial statements
 and supporting schedule are free of material misstatement.  An audit
 includes examining, on a test basis, evidence supporting the amounts
 and disclosures in the financial statements and supporting schedule. 
 An audit also includes assessing the accounting principles used and
 significant estimates made by management, as well as evaluating the
 overall financial statement presentation.  We believe that our audits
 provide a reasonable basis for our opinion.

 In our opinion, the consolidated financial statements referred to above
 present fairly, in all material respects, the financial position of
 Wausau-Mosinee Paper Corporation and Subsidiaries at December 31, 1998
 and 1997, and the results of its operations and cash flows for the
 years ended December 31, 1998 and 1997 and August 31, 1996, and the
 supporting schedule presents fairly the information required to be set
 forth therein, all in conformity with generally accepted accounting
 principles.

         WAUSAU-MOSINEE PAPER CORPORATION AND SUBSIDIARIES
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

 NOTE 1.  SIGNIFICANT ACCOUNTING POLICIES

 BASIS OF PRESENTATION - The consolidated financial statements include
 the accounts of the Company and its subsidiaries. All significant
 intercompany transactions, balances and profits have been eliminated in
 consolidation.  The consolidated statements give retroactive effect to
 the merger with Mosinee Paper Corporation ("Mosinee").

 On December 17, 1997, Wausau Paper Mills Company ("Wausau") completed a
 merger with Mosinee ("the Mosinee merger") in which Mosinee became a
 wholly owned subsidiary of Wausau.  Simultaneous with the consummation
 of the Mosinee merger, Wausau changed its name to Wausau-Mosinee Paper
 Corporation ("the Company"). Prior to the merger, Wausau's fiscal
 year-end was August 31 and Mosinee's was December 31. Subsequent to the
 Mosinee merger, the Company adopted a calendar year-end. As a result of
 the change in fiscal year and the merger accounted for as a pooling of
 interests, the Company's 1997 financial statements have been recast to
 a twelve-month period ending December 31, 1997.  The financial
 statements have been restated to retroactively combine Mosinee's
 financial statements as if the merger had occurred at the beginning of
 the earliest period presented.

 The consolidated statements of income and cash flows for the year ended
 August 31, 1996 reflect the results of operations and cash flows for
 Wausau for the year then ended combined with Mosinee for the year ended
 December 31, 1996.  The consolidated balance sheet as of August 31,
 1996 reflects the financial position of Wausau on that date combined
 with the financial position of Mosinee as of December 31, 1996.  As a
 result of Wausau and Mosinee having different fiscal years and the
 change in the Company's fiscal year, Wausau's results of operations for
 the four-month period ended December 31, 1996, have been excluded from
 the reported results of operations and, therefore, have been added to
 the Company's retained earnings at January 1, 1997. Wausau had
 net sales, expense, and net income of $179,075,000, $165,255,000, and
 $13,820,000 for the four-month period ended December 31, 1996.

 REVENUE RECOGNITION - Revenue is recognized upon shipment of goods and
 transfer of title to the customer.  The Company grants credit to
 customers in the ordinary course of business.  A substantial portion of
 the Company's accounts receivable is with customers in various paper
 converting industries or the paper merchant business.  Concentrations
 of credit risk with respect to trade receivables are limited due to the
 large number of customers and their geographic dispersion.

 USE OF ESTIMATES IN PREPARATION OF CONSOLIDATED FINANCIAL STATEMENTS -
 The preparation of the accompanying financial statements in conformity
 with generally accepted accounting principles requires management to
 make estimates and assumptions that affect the reported amounts of
 assets, liabilities, revenue and expenses.  Actual results may differ
 from these estimates.

 CASH EQUIVALENTS - The Company defines cash equivalents as highly
 liquid, short-term investments with an original maturity of three
 months or less.
<PAGE>
 INVENTORIES - Pulpwood, finished paper products and the majority of raw
 materials are valued at the lower of cost, determined on the last-in,
 first-out (LIFO) method, or market. All other inventories are valued at
 the lower of average cost or market.  Allocation of the LIFO reserve
 among the components of inventories is impractical.

                                     -31-

 PROPERTY, PLANT AND EQUIPMENT - Plant and equipment are stated at cost
 and are depreciated over the estimated useful lives of the assets using
 the straight-line method for financial statement purposes. Land, water
 power rights, and construction in progress are stated at cost.  The
 cost and related accumulated depreciation of all plant and equipment
 retired or otherwise disposed of are removed from the accounts, and any
 resulting gains or losses are included in the statements of income.

 Buildings are depreciated over a 20 to 45-year period; machinery and
 equipment over a 3 to 20-year period. Maintenance and repair costs are
 charged to expense as incurred. Renewals and improvements which extend
 the useful lives of the assets are added to the plant and equipment
 accounts.

 Equipment financed by long-term leases, which in effect are installment
 purchases, have been recorded as assets and the related obligations as
 debt.  Depreciation expense includes amortization on capitalized
 leases.

 Timberlands are stated at net depleted value. Depletion expense is
 calculated using the block and unit-of production methods.  The block
 method groups timberland into logical management areas called "blocks"
 for which the cost basis is determinable.  The annual depletion is
 determined by multiplying the per unit cost basis of the block of
 timber by the number of units harvested from the block during the year.

 INCOME TAXES - Deferred income taxes have been provided under the
 liability method.  Deferred tax assets and liabilities are determined
 based upon the estimated future tax effects of differences between the
 financial statement and tax bases of assets and liabilities, as
 measured by the current enacted tax rates.  Deferred tax expense is the
 result of changes in the deferred tax asset and liability.

 EARNINGS PER SHARE - Basic earnings per common share are based on the
 weighted average number of common shares outstanding.  Diluted earnings
 per common share are based on the weighted average number of common
 shares and common stock equivalents (options) outstanding.

 FUTURES CONTRACTS - The Company utilizes futures contracts to
 periodically hedge the price risk of anticipated purchases of pulp and
 other commodity products. Changes in the market value of the futures
 contracts are included as part of the acquisition price of pulp and
 other commodity products and are realized when the finished paper is
 sold and the other commodity products are consumed.  Statement of
 Financial Accounting Standards (SFAS) No. 133, "Accounting for
 Derivative Instruments and Hedging Activities" will be adopted as of
 January 1, 2000.  The statement establishes accounting and reporting
 standards for derivatives. The effect on the Company is not expected to
 be material.
<PAGE>
 CHANGES IN ACCOUNTING POLICIES - On January 1, 1998, the Company
 adopted Statements of Financial Accounting Standards (SFAS) No. 130,
 "Reporting Comprehensive Income," No. 131, "Disclosures about Segments
 of an Enterprise and Related Information," and No. 132, "Employers'
 Disclosures about Pensions and Other Postretirement Benefits." SFAS No.
 130 requires companies to report all changes in net assets, such as
 minimum pension liability adjustments, as a component of comprehensive
 income.  SFAS No. 131 requires certain disclosures of the company's
 segments including general information, segment profits and assets, and
 a reconciliation of segment financial condition and results of
 operations to the corresponding company amounts. SFAS No. 132 revises
 employers' disclosures about pension and other postretirement benefit
 plans.

                                     -32-

 NOTE 2.  MERGERS AND ACQUISITIONS

 On December 17, 1997, the Company completed the Mosinee merger. The
 merger qualified as a tax-free exchange and was accounted for as a
 pooling of interests.  Wausau issued 1.4 shares of common stock for
 each share of Mosinee outstanding common stock. A total of 21,281,795
 shares (after adjustment for fractional shares) of the Company's common
 stock was issued as a result of the merger, and Mosinee's outstanding
 stock options were converted into options to purchase approximately
 596,000 common shares.  In connection with the merger, the Company
 incurred $13,503,000 ($13,203,000 after taxes, or $ .23 per common
 share) of merger-related costs which were charged to operations during
 the year ended December 31, 1997.

 The following table presents a reconciliation of net sales and net
 earnings previously reported by the Company to those presented in the
 accompanying consolidated financial statements.

 believes are necessary to fairly present such information. Historical
 costs representing the seller's corporate allocations, interest expense
 and one-time expenses related to the sale of Otis are included in the
 pro forma information. The pro forma information does not purport to

                                     -33-

 operations would actually have been if this transaction had occurred at
 the beginning of the earliest period presented.

 On April 1, 1997, Mosinee acquired the business and assets of B&J
 Supply, Inc. ("B&J"), a converter and nationwide supplier of school
 papers.  The acquisition was accounted for using the purchase method of
 accounting.  The results of operations of B&J from the date of purchase
 have been included in the reported results of operations since the date
 of acquisition.  Had the purchase been consummated at the beginning of
 fiscal 1997, operating results on a pro forma basis would not have been
 significantly different.

 NOTE 3.  RESTRUCTURING

 In March 1998, the Company began implementation of a workforce
 reduction program.  The purpose of the program was to reduce the number
 of employees by 400 through early retirement incentives along with
 voluntary separation arrangements, involuntary severance programs and
 process automation.  As a result of the program implementation, the
 Company recorded a pre-tax restructuring charge of $37.7 million in the
 first quarter of 1998.  The charge was based on estimates of the cost
 of the workforce reduction program, including special termination
 benefits and settlement and curtailment losses related to pension and
 postretirement benefit plans. In the fourth quarter of 1998, an
 additional pre-tax expense of $5.1 million was recorded to recognize
 adjustments to the previous estimates of the early retirement
 incentives and to recognize additional expenses associated with
 integration costs.  Approximately 93% of the benefits under the program
 have been paid or have been transferred as obligations of the Company's
 retirement plans as of December 31, 1998.

 NOTE 5.  DEBT

 The Company's short-term notes payable consist of $20,000,000
 outstanding under an unsecured debt arrangement with one financial
 institution and $25,466,000 outstanding under two separate revolving
 lines of credit.

                                     -35-

 The $20,000,000 unsecured debt arrangement was entered into by the
 Company on September 30, 1994, at an interest rate of 7.83%. Interest
 is paid monthly and the principal is due September 1999. At December
 31, 1997, the $20,000,000 was classified as long-term debt.
<PAGE>
 During 1998, two banks participating in the revolving credit
 arrangement with the Company provided separate lines of credit. One
 line of credit provides for borrowing up to $20,000,000. Specific rates
 and terms of the loans are determined at the time of borrowing, with
 maturity not to go beyond September 30, 1999. The line of credit does
 not require a compensating balance or a commitment fee.  At December
 31, 1998, there was $17,000,000 borrowed against this line of credit at
 a weighted average interest rate of 5.65%.  The second line of credit
 provides for borrowing up to $60,000,000 at rates and terms negotiated
 at the time of borrowing, with maturity not to go beyond November 22,
 1999.  The line of credit agreement provides for a commitment fee
 during the term of the agreement. The fee is based on a quarterly debt
 to EBITDA ratio. Based on the debt to EBITDA ratio at December 31,
 1998, the fee is .125% per annum on the unused portion of this line of
 credit.  At December 31, 1998, there was $22,000,000 borrowed against
 this line of credit at a weighted average interest rate of 5.77%.  As of
 December 31, 1998, of the total borrowings against the lines of credit,
 $25,466,000 is classified as short-term and $13,534,000 is classified
 as long-term as the Company intends and has the ability to refinance
 the obligations under the revolving credit agreement.

 The Company's long-term debt, excluding current maturities as of
 December 31, consists of the following:

 Totals                              $127,000       $ 140,500
</TABLE>

 The Company has outstanding $9 million in unsecured senior promissory
 notes.  Interest is payable quarterly on the outstanding balance at a
 rate of 6.03% per annum. Principal is payable in equal semi-annual
 installments, with the final payment due June 16, 2000.

 During 1995, the Company borrowed $19 million related to industrial
 development bonds issued by a local governmental unit. The variable
 rate bonds require quarterly interest payments and had an interest rate
 of 4.30% at December 31, 1998 and 4.45% at December 31, 1997.  The
 Company also pays fees for a bank letter of credit and remarketing
 services related to the bonds which it includes in net interest
 expense.  The interest rate can be converted to a fixed rate, at the
 Company's option, after which semi-annual interest payments will be
 required.  The bonds mature on July 1, 2023. At December 31,
 1998 and December 31, 1997, all bond proceeds had been disbursed.

                                     -36-
<PAGE>
 The Company maintains an unsecured revolving credit facility of $105
 million with four banks which continues through March 29, 2001 at which
 time, or earlier at the Company's option, the revolving credit converts
 to a term loan facility, and the loans then outstanding are payable in
 four equal quarterly installments.  The Company may elect the base for
 interest from either domestic rate loans, eurodollar loans, adjusted CD
 rate loans, offered loans or treasury rate loans.  The weighted average
 interest rate on borrowings under the revolving credit facility was
 5.58% and 6.14% at December 31, 1998 and December 31, 1997,
 respectively. The credit agreement provides for commitment fees during
 the revolving loan period.  Fees are based on quarterly funded debt to
 equity levels. Based on debt and equity levels at December 31, 1998 and
 December 31, 1997, the fees are .1% per annum.

 The senior promissory notes, long-term note and the revolving credit
 facility agreements require the Company to comply with certain
 covenants, one of which requires the Company maintain minimum net
 worth.  At December 31, 1998, $242 million of retained earnings was
 available for payment of cash dividends without violation of the
 minimum net worth covenant related to the senior promissory notes.

 The Company maintains a commercial paper placement agreement with a
 bank to issue up to $40 million of unsecured debt obligations which
 requires unused credit availability under its revolving credit
 agreement equal to the amount of outstanding commercial paper.  At
 December 31, 1998 and December 31, 1997, $16,466,000 and $10,485,000
 were outstanding, respectively. The weighted average interest rate on
 outstanding commercial paper was 5.6% at December 31, 1998 and 6.2% at
 December 31, 1997.

 One of the Company's wholly owned subsidiaries had a commercial paper
 placement agreement to issue up to $50 million of unsecured debt
 obligations.  At December 31, 1997, $11,464,000 was outstanding.  The
 weighted average interest rate on commercial paper outstanding at
 December 31, 1997 was 6.1%.  All commercial paper was retired in June
 1998 and this agreement is no longer in effect.

 The aggregate annual maturities of long-term debt are as follows:

 NOTE 8.  RETIREMENT AND OTHER POSTRETIREMENT BENEFIT PLANS

 Substantially all employees are covered under retirement plans. The
 defined benefit plans covering salaried employees provide benefits
 based on final average pay formulas; the plans covering hourly
 employees provide benefits based on years of service and fixed benefit
 amounts for each year of service.  The plans are funded in accordance
 with federal laws and regulations.

 The Company selected measurement dates of plan assets of September 30,
 1998 and 1997.

 In 1998, the Company offered a voluntary early retirement program to
 encourage early retirements among certain salaried and hourly
 employees.  The program was part of the restructuring plan discussed in
 Note 3 to the consolidated financial statements. As a result,
 curtailment and settlement charges of $5.9 million and special
 termination benefit charges of $23.3 million were recorded as a
 component of the restructuring expense recognized in 1998.

 The following are reconciliations of the projected benefit obligations
 and the value of plan assets for 1998 and 1997:

 The Company also sponsors defined contribution pension plans, several
 of which provide for Company contributions based on a percentage of
 employee contributions. The cost of such plans totaled $3,066,000 in
 1998, $3,872,000 in 1997 and $3,983,000 in 1996.

 The Company has deferred compensation or supplemental retirement
 agreements with certain present and past key officers, directors, and
 employees.  The principal cost of such plans is being or has been
 accrued over the period of active employment to the full eligibility
 date.  The annual cost of the deferred compensation and supplemental
 retirement agreements does not represent a material amount.

 The Company sponsors unfunded defined benefit postretirement health and
 life insurance plans that cover substantially all employees reaching
 normal retirement age while working for the Company.  Benefits and
 eligibility for various employee groups vary by location and union
 agreements.  Generally, employees are eligible after reaching age 55 or
 62 and meeting minimum service requirements. At age 65, the benefits
 become coordinated with Medicare.  The Company funds the benefit costs
 on a current basis.

 postretirement benefit obligation ranged from 8% to 9%, declining 1%
 annually for three to four years to an ultimate rate of 5%.

 NOTE 9.  INCOME TAXES

 Deferred tax assets and liabilities are determined based on the
 estimated future tax effects of temporary differences between the
 financial statement and tax bases of assets and liabilities, as
 measured by the current enacted tax rates. Deferred tax expense
 (benefit) is the result of changes in the deferred tax asset and
 liability.

 At the end of 1998, $18,000,000 of unused state operating loss
 carryovers existed which may be used to offset future state taxable
 income in various amounts through the year 2010.  Because separate
 state tax returns are filed, the Company is not able to offset
 consolidated income with the subsidiaries' losses. Under the provisions
 of SFAS No. 109, the benefits of state tax losses are recognized as a
 deferred tax asset, subject to appropriate valuation allowances.

 NOTE 10.  STOCK OPTIONS AND APPRECIATION RIGHTS

 The Company maintains the 1991 Employee Stock Option Plan. The plan
 specifies purchase price, time and method of exercise. Payment of the
 option price may be made in cash or by tendering an amount of common
 stock having a fair market value equal to the option price.

 Options are granted for terms up to 20 years, the option price being
 equal to the fair market value of the Company's common stock at the
 date of grant for incentive and non-qualified options.

 The following table summarizes the activity relating to the Company's
 stock option plans:

 All shares and option prices have been restated to reflect the five-for
 -four stock split occurring in 1996.

 The Company has adopted Statement of Financial Accounting Standard
 (SFAS) No. 123, "Accounting for Stock-Based Compensation." As permitted
 under SFAS No. 123, the company will continue to measure compensation
 cost for stock option plans using the "intrinsic value based method"
 prescribed under APB No. 25, "Accounting for Stock Issued to
 Employees."  Accordingly, no compensation cost has been recognized for
 the stock option plans.  If compensation cost had been determined
 consistent with the provisions of SFAS No. 123, which prescribes the
 "fair value based method" on the grant date, both basic and diluted
 earnings per share would have been $.73, $1.12 and $1.14 for the years
 ended December 31, 1998 and 1997 and August 31, 1996, respectively.
 The weighted-average grant-date exercise prices and weighted-average

 The 1988 Management Incentive Plan entitles certain management
 employees the right to receive cash equal to the sum of the
 appreciation in value of the stock and the hypothetical value of cash
 dividends which would have been paid on the stock covered by the grant
 assuming reinvestment in Company stock.  The stock appreciation rights
 granted may be exercised in whole or in such installments and at such
 times as specified in the grant. In all instances, the rights lapse
 if not exercised within 20 years of the grant date.  Compensation
 expense is recorded with respect to the rights based upon the quoted
 market value of the shares and the exercise provisions.

 The following table summarizes the activity relating to the Company's
 stock appreciation rights plans:

 $4,980,000, respectively.

 NOTE 11. RESEARCH EXPENSES

 Research expenses charged to operations were $3,309,000 in 1998,
 $1,577,000 in 1997 and $1,381,000 in 1996.

 NOTE 12.  COMMITMENTS AND CONTINGENCIES

 In 1997, the Attorney General of the State of Florida filed a civil
 complaint in the United States District Court for the Northern
 District of Florida against ten manufacturers of commercial sanitary
 paper products, including the Company's wholly owned subsidiary, Bay
 West Paper Corporation. The lawsuit alleges a conspiracy to fix prices
 of commercial sanitary paper products starting at least as early as
 1993. Since the filing of this lawsuit, numerous class action suits
 have been filed by private direct purchasers of commercial sanitary
 paper products in various federal district courts throughout the
 country and additional federal lawsuits have been filed by the
 Attorneys General of the States of Kansas, Maryland, New York, and
 West Virginia. All of these federal cases have been certified as class
 actions and consolidated in a multi-district litigation proceeding in
 the United States District Court for the Northern District of Florida
 in Gainesville. Certain indirect purchasers of sanitary commercial
 paper products have also filed class action lawsuits in various state
 courts alleging a conspiracy to fix prices under state antitrust laws.
 No class has been certified in the state actions. All of these actions
 are in early stages. In the opinion of management, the Company has not
 violated any antitrust laws. The Company is vigorously defending these
 claims.  The Company is also involved from time to time in various
 other legal and administrative proceedings or subject to various claims
 in the normal course of its business. In the opinion of management, the
 ultimate disposition of these matters will not have a material adverse
 effect on the consolidated financial condition, liquidity, or results
 of operations of the Company.
<PAGE>
 As of December 31, 1998, the Company was committed to spend
 approximately $70 million to complete capital projects which were
 in various stages of completion.

                                     -48-

 The Company is a party to a natural gas transportation agreement with
 the Portland Natural Gas Transmission System (PNGTS). Under the terms
 of the agreement, PNGTS has constructed the necessary gas supply and
 delivery equipment to the Company's Groveton, New Hampshire mill. The
 Company is committed to the transportation of a fixed volume of natural
 gas over a 20-year period which begins on the date transportation of
 natural gas commences under the agreement. Capital improvements to the
 Groveton mill's power plant, which the Company estimates will cost
 approximately $1.5 million, will be required to take advantage of this
 agreement. Transportation of natural gas to the Groveton mill is
 expected to begin in the third quarter of 1999.

 NOTE 13. PREFERRED SHARE PURCHASE RIGHTS PLAN

 On October 21, 1998, the Board of Directors declared a dividend of one
 preferred share purchase right (a "Right") for each outstanding share
 of common stock of the Company (the "Common Shares"). Each Right
 entitles the registered holder to purchase from the Company one
 one-thousandth of a share of Series A Junior Participating Preferred
 Stock of the Company, without par value (the "Preferred Shares"), at a
 price of $60 per one one-thousandth of a Preferred Share (the 
 "Purchase Price"), subject to adjustment. In the event that any person
 or group (with certain exceptions) acquires beneficial ownership of 15%
 or more of the outstanding Common Shares (an "Acquiring Person"), each
 holder of a Right, other than the Acquiring Person, will thereafter
 have the right to receive upon exercise that number of Common Shares
 having a market value of two times the exercise price of the Right. If
 the Company is acquired in a merger or other business combination
 transaction or 50% or more of its consolidated assets or earning power
 are sold after a person or group has become an Acquiring Person, each
 holder of a Right, other than an Acquiring Person, will thereafter have
 the right to receive that number of shares of common stock of the
 acquiring company which at the time of such transaction will have a
 market value of two times the exercise price of the Right.

 The Rights are not exercisable until the Distribution Date.  Until a 
 Right is exercised, the holder thereof, as such, will have no rights as
 a shareholder of the Company. The "Distribution date" is the earlier of
 (i) 10 days following a public announcement that a person or group has
 become an Acquiring Person; or (ii) 10 business days (or such later
 date as may be determined by action of the Board of Directors)
 following the commencement of, or announcement of an intention to make,
 a tender offer or exchange offer which would result in any person
 becoming an Acquiring Person. The Rights will expire on October 31,
 2008 unless the expiration date is extended or unless the Rights are
 redeemed or exchanged by the Company prior to expiration.

 The Purchase Price payable, and the number of Preferred Shares or other
 securities or property issuable, upon exercise of the Rights are subject to
 adjustment from time to time to prevent dilution in the event of stock
 dividends, stock splits, reclassifications, or certain distributions with
<PAGE>
 respect to the Preferred Shares. The number of outstanding Rights and
 the number of one one-thousandths of a Preferred Share issuable upon
 exercise of each Right are also subject to adjustment if, prior to the
 Distribution Date, there is a stock split, a stock dividend in Common
 Shares, or a subdivision or consolidation of the Common Shares.

 Preferred Shares purchasable upon exercise of the Rights will not be
 redeemable. Each Preferred Share will be entitled to a minimum
 preferential quarterly dividend payment of $10 per share, but will be
 entitled to an aggregate dividend of 1000 times the dividend declared
 
                                     -49-

 per Common Share. In the event of liquidation, the holders of the
 Preferred Shares will be entitled to a minimum preferential liquidation
 payment of $1000 per share, but will be entitled to an aggregate
 payment of 1000 times the payment made per Common Share.  Each
 Preferred Share will have 1000 votes, voting together with the Common
 Shares.  Finally, in the event of any merger, consolidation or other
 transaction in which Common Shares are exchanged, each Preferred Share
 will be entitled to receive 1000 times the amount received per Common
 Share. The value of the one one-thousandth interest in a Preferred
 Share purchasable upon exercise of each Right should approximate the
 value of one Common Share.

 At any time after any person or group becomes an Acquiring Person, and
 prior to the acquisition by such person or group of 50% or more of the
 outstanding Common Shares, the Board of Directors may exchange the
 Rights, other than Rights owned by the Acquiring Person, in whole or in
 part, at an exchange ratio of one Common Share, or one one-thousandth
 of a Preferred Share (subject to adjustment). At any time prior to any
 person or group becoming an Acquiring Person, the Board of Directors
 may redeem the Rights in whole, but not in part, at a price of $ .01
 per Right.

 The terms of the Rights may be amended by the Board of Directors
 without the consent of the holders of the Rights, including an
 amendment to lower certain thresholds described above to not less than
 the greater of (i) the sum of .001% and the largest percentage of the
 outstanding Common Shares then known to the Company to be beneficially
 owned by any person or group affiliated or associated persons (with
 certain exceptions) and (ii) 10%, except that from and after such time
 as any person or group becomes an Acquiring Person no such amendment
 may adversely affect the interests of the holders of the Rights.

 NOTE 14.  FUTURES CONTRACTS

 At December 31, 1998, the Company was party to various futures
 contracts for the purchase of natural gas and fuel oil. The natural gas
 contracts require the Company to purchase 575,000 decatherms of natural
 gas during 1999.  The delivered price of natural gas varies from $2.73
 to $3.42 per decatherm.  The fuel oil contracts require the Company to
 purchase 146,000 barrels of oil during 1999. The delivered price of oil
 varies from $13.95 to $17.19 per barrel.  At December 31, 1998, the
 Company's futures contracts have no carrying value. The fair value of
 the contracts and the total deferred gain or loss on the contracts are
 immaterial at December 31, 1998.
<PAGE>
 NOTE 15. FAIR VALUES OF FINANCIAL INSTRUMENTS

 The fair value of the following financial instruments is not materially
 different from the carrying value: cash and cash equivalents, long-term
 debt, capital leases and futures contracts.

 The following methods and assumptions were used by the Company in
 estimating fair values of financial instruments:

 Cash and cash equivalents - The carrying amount approximates fair value
 due to the relatively short period to maturity for these instruments.

 Long-term debt - The fair value of the Company's long-term debt is
 estimated based on current rates offered to the Company for debt of the
 same remaining maturities.

 Capital leases - The carrying amount reported in the balance sheets for
 capital leases approximates fair value.

                                     -50-

 Futures contracts - The fair values of the Company's commodity products
 futures contracts were estimated using the prices published by NYMEX,
 the contract price and the remaining commodity products to be purchased
 under the contracts.

 NOTE 16. SEGMENT DATA

 FACTORS USED TO IDENTIFY REPORTABLE SEGMENTS
 The Company's operations are classified into three principal reportable
 segments, the Specialty Paper Group, the Printing & Writing Group and
 the Towel & Tissue Group, each providing different products. Separate
 management of each segment is required because each business unit is
 subject to different marketing, production and technology strategies.

 PRODUCTS FROM WHICH REVENUE IS DERIVED
 The Specialty Paper Group produces specialty papers at its
 manufacturing facilities in Rhinelander, Wisconsin; Mosinee, Wisconsin;
 Jay, Maine; and Middletown, Ohio. The Printing & Writing Group produces
 a broad line of premium printing and writing grades at manufacturing
 facilities in Brokaw, Wisconsin and Groveton, New Hampshire.  The
 Printing & Writing Group also includes two converting facilities which
 produce wax-laminated roll wrap and related specialty finishing and
 packaging products, and a converting facility which produces school
 papers.  The Towel & Tissue Group manufactures a complete line of
 towel, tissue, soap and dispensing systems for the "away-from-home"
 market. The Towel & Tissue Group operates a paper mill in Middletown,
 Ohio and a converting facility in Harrodsburg, Kentucky.

 MEASUREMENT OF SEGMENT PROFIT AND ASSETS
 The Company evaluates performance and allocates resources based on
 operating profit or loss. The accounting policies of the reportable
 segments are the same as those described in the summary of significant
 accounting policies.

           as herein set forth.

     (h)  "Retirement Plan" shall mean the principal defined benefit
           retirement plan as now in effect or hereafter amended, or any
           successor plan which is qualified under Section 401(a) of the
           Code, and maintained for salaried employees of the Company.

     2.2  DEFINITIONS INCORPORATED BY REFERENCE.  Each of the following
 terms shall have the meaning set forth in the Retirement Plan and the

     (d)  Notwithstanding anything herein to the contrary, if a
          Participant was a participant in the Wausau Paper Mills
          Company Executive Officers' Deferred Compensation Retirement
          Plan or the Mosinee Supplemental Retirement Plan on December
          16, 1997, all Continuous Service recognized under such plans

                             BENEFITS

     4.1  NORMAL RETIREMENT BENEFITS OF CORPORATE OFFICERS.  Subject to
 the limitations elsewhere contained in this Plan, an Executive Officer
 who terminates his employment with the Company and each Affiliated
 Employer on or after attaining his Normal Retirement Age and who was
 the President or a corporate Vice President of the Company either (x)
 on the Effective Date or (y) as of the most recent date on which he
 performed service as an Executive Officer shall be entitled to a normal
 retirement benefit payable in the form of a single life annuity equal
 to the excess of:

     (a)  an amount equal to 50% of the Participant's Average
          Compensation, over

     (b)  the amount of the Participant's accrued Retirement Benefit
          under the Retirement Plan which would then be payable in the
          form of a single life annuity;

 provided, however, that (1) the normal retirement benefit payable in
 the form of a single life annuity, as so calculated, of any Participant
 who was a participant in the Mosinee Supplemental Retirement Plan on
 the Effective Date shall be increased by an amount equal to such
 participant's accrued normal retirement benefit under the Wausau Paper
 Retirement Plan as of the Effective Date which would then be payable in
 the form of a single life annuity and (2) the normal retirement benefit
 payable in the form of a single life annuity, as so calculated, of any

 Plan (Section "3.20") shall be increased by an amount equal to the
 excess of (A) the amount of the Participant's accrued Retirement
 Benefit under the Retirement Plan, determined in accordance with the
 increased benefits provided for in Section 4.23 or Section 3.20, as
 applicable, which would then be payable in the form of a single life
 annuity over (B) the amount of the Participant's accrued Retirement
 Benefit under the Retirement Plan, determined without regard to the
 increased benefits provided for in Section 4.23 or Section 3.20, as
 applicable, which would then be payable in the form of a single life
 annuity.

 limitations elsewhere contained in this Plan, an Executive Officer who
 terminates his employment with the Company and each Affiliated Employer
 on or after attaining his Normal Retirement Age and who was not the

 retirement benefit payable in the form of a single life annuity
 determined in accordance with the formula set forth in Section 4.1;

                                     -6-
<PAGE>
     4.3  MINIMUM RETIREMENT BENEFITS OF EXECUTIVE OFFICERS.
 Notwithstanding anything herein to the contrary, the normal retirement
 benefit determined under Section 4.1 or 4.2, as applicable, shall not
 be less than the Participant's accrued normal retirement benefit
 determined under (a) Section 4.1 or 4.2, as applicable, under the
 Mosinee Supplemental Retirement Plan or (b) Section 4.1 or 4.2, as
 applicable, under the Wausau Paper Mills Company Executive Officers'
 Deferred Compensation Retirement Plan, determined under the terms of
 such plans on December 16, 1997.

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

     4.5  SURVIVING SPOUSE BENEFITS.  Subject to the limitations
 elsewhere contained in this Plan, the Surviving Spouse of a Participant
 who dies prior to commencement of any other benefit hereunder,
 including the Surviving Spouse of a former Participant who terminated
 employment because of Disability, shall be eligible for a Surviving
 Spouse benefit commencing as of the last to occur of (1) the first day
 of the first month following the month in which the Participant's death
 occurs or (2) the date on which the Participant would have been
 eligible to receive payment of a benefit under Section 4.4, or in the
 case of a Participant who terminated employment because of Disability,
 commencing as of the date on which the former Participant would have
 attained age 55, and such Surviving Spouse benefit shall be equal to
 50% of the monthly benefit which would have been payable to the
 deceased Participant under this Plan if he had retired the day before
 his death and payment of his benefit had commenced on such date
 assuming, in the case of a former Participant who terminated employment
 because of a Disability, that the benefit payable to such former
 Participant at Normal Retirement Age under Section 4.1 or 4.2, as
 applicable, would have been payable in reduced form at age 55 pursuant
 to Section 4.4, and, assuming further, that in the case of a
 Participant or former Participant who died prior to attaining age
 55 or prior to the date on which the Participant or former Participant
 had completed 10 years of Continuous Service, that a benefit would have
 been payable to such deceased Participant or former Participant as of
 the later of the dates described in (1) and (2), above; provided,
 however, that the benefit payable to the Surviving Spouse of a
 Participant or former Participant who died prior to the completion of 5
 years of Continuous Service shall be reduced by 20% for each year of
 Continuous Service less than 5 accrued by such deceased Participant or
 former Participant.

     4.6  FORM, COMMENCEMENT AND DURATION OF PAYMENTS.
     (a)  A Participant may elect, subject to the approval of the Board
          of Directors, (1) to receive the Actuarial Equivalent of the
          benefit accrued by a Participant pursuant to Section 4.1, 4.2
          or 4.4 in any form of annuity payment option then available
          under the Retirement Plan or (2) to receive the value of the
          benefit accrued by a Participant pursuant to Section 4.1, 4.2
          or 4.4 in the form of a lump sum distribution.  In the event a
          Participant elects, with the approval of the Board of
          Directors, to receive a lump sum distribution of the value of
          the benefit otherwise provided for in Section 4.1, 4.2, or
          4.4, the value of the lump sum distribution under this Plan
          shall be determined in accordance with the provisions for
          determining the value of a lump sum distribution of the
          Participant's Retirement Benefit under the terms of the
          Retirement Plan.

     (b)  Monthly benefit payments to the Participant (and, if
          applicable, his Surviving Spouse) under Section 4.1, 4.2, 4.4
          or 4.5, or a lump sum payment provided for under Section
          4.5(a) with respect to a benefit accrued under Section 4.1,
          4.2 or 4.4, shall commence on the first day of the month
          following the Participant's termination of employment or, if
          applicable, the date specified in Section 4.5 as the date on
          which the Participant's Surviving Spouse became eligible for a
          Surviving Spouse benefit, and shall continue, subject to the
          provisions of Section 4.8, until the month in which the death
          of the Participant (or, if applicable, his Surviving Spouse)
          occurs; provided, however, that a Participant or Surviving
          Spouse may elect to defer receipt of an early retirement
          benefit or Surviving Spouse benefit, as applicable, for any
          period of time not in excess of the date on which the
          Participant would have attained his Normal Retirement Age.
          Despite any other provision of this Plan, a Participant who
          receives a benefit in the form of a lump sum distribution
          shall not be entitled to any monthly benefit otherwise
          provided for in this Plan.

     (c)  A Participant (or, if applicable, his Surviving Spouse) who
          has begun to receive his accrued benefit in the form of an
          annuity pursuant to Section 4.6(a), may, subject to the
          consent of the Board of Directors, elect to receive the unpaid
          value of his annuity in the form of a lump sum distribution.
          The value of such lump sum distribution shall be determined in
          accordance with the same actuarial assumptions and interest
          rate then being used to determine the value of a lump sum
          distribution of a participant's Retirement Benefit under the
          terms of the Retirement Plan.  The payment of such lump sum
          distribution shall be made in accordance with the terms of the
          consent of the Board of Directors to such payment.

                                     -8-

     4.7  CHANGE OF CONTROL.

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

     (b)  In the event a Change of Control of the Company occurs after
          the Participant's death and whether or not a benefit shall
          have then become payable to the Participant's Surviving
          Spouse, the Company shall pay to such Participant's Surviving

          provided for in this Section 4.7(b), the Company shall have no
          further obligation to pay any benefits under this Plan.
          Notwithstanding the foregoing, if a Participant had less than
          five years of Continuous Service as of the date of his or her
          death before the Change of Control, the amount paid to such
          Participant Surviving Spouse under this Section 4.7(b) shall
          equal (i) the amount described in the first sentence of this
          Section 4.7(a) times (ii) a fraction, the numerator of which
          is the number of years and fractions thereof of the
          Participant's Continuous Service as of the date of death and
          the denominator of which is five.

          Company" shall mean:

               (1)  The acquisition by any individual, entity or group

          successor regulation adopted for the same or substantially
          similar purpose.

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

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

     (b)  In the event a Participant, without the prior written consent
          of the Company and within a period of two years beginning on
          the first day following the Participant's termination of
          employment with the Company, directly or indirectly owns,
          manages, operates, joins, controls, is employed by or
          participates in the ownership, management, operation or
          control of, or is connected in any manner with, any business
          of a type and character which, in the opinion of the Company,
          results in the Participant then being engaged in the field of
          activities in which he was engaged by the Company at the time
          of termination (and within one year prior to said termination)
          and such business is, in the opinion of the Company, in direct
          or indirect competition in any market area served by the
          Company with any business then conducted by the Company in
          such market area, no payment of any benefit otherwise due the
          Participant or his Surviving Spouse pursuant to this Plan
          shall be made by the Company if the Participant fails to cease
          such activity within fifteen days of the mailing to him by the
          Company of the Company's opinion that he is in violation of
          the restrictions contained in this Section 4.8(b).

<PAGE>
     (c)  The Company shall have sole discretion to stop payment of any
          benefit or refuse to make payments otherwise due the
          Participant or his Surviving Spouse pursuant to this Plan if
          the Participant's termination of employment with the Company
          or his appointment to a position with the Company as other
          than an Executive Officer was by reason of or because of the
          Participant's fraud, embezzlement, misappropriation or similar
          offense against the Company or any other state or federal
          felony offense.

     (d)  Subject to the provisions of Section 6.2, no benefit shall be
          payable under this Plan to any Participant or Surviving Spouse
          who, for any reason, is not eligible for and does not receive
          a benefit under the provisions of the Retirement Plan.

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

     4.10  FACILITY OF PAYMENTS.  Any benefit payable hereunder to any
 person who is legally incapacitated may be paid to a court appointed
 legal representative of such person.

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

                             ARTICLE V
                      PROVISION FOR BENEFITS

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

                            ARTICLE VI
               AMENDMENT AND TERMINATION OF THE PLAN

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

     6.2  TERMINATION.  The Company reserves the right to terminate the
 Plan at any time and for any reason; provided, however, that upon
 termination, each Participant's accrued benefit shall be fully vested
 subject only to the provisions of Section 4.8.  A Participant's
 "accrued benefit" shall mean the benefit which would be paid or payable
 pursuant to this Plan following the Participant's termination of
 employment if the Retirement Plan had terminated as of the same date on
 which the termination of the Plan occurs (and provided for payment of
 accrued Retirement Plan benefits upon the Participant's termination of
 employment) multiplied by a fraction, the numerator of which is a
 Participant's years of Continuous Service recognized under Section 3.2
 and the denominator of which is ten.

 capacity, or as a limitation of the right of the Company to discharge
 any of its employees, with or without cause.

 Plan may be by resolution of its Board of Directors, or by any officer

                                     -1-

 subsidiaries shall be eligible for participation in the Plan; (ii) to
 select employees to receive grants under the plan; (iii) to determine
 the number of stock appreciation rights subject to the grant, the time
 and conditions of exercise or vesting, the fair market value of the
 common stock of the Corporation for purposes of the Plan, and all other
 terms and conditions of any grant; and (iv) to prescribe the form of
<PAGE>
 agreement, certificate or other instrument evidencing the grant.  The
 Committee shall also have authority to interpret the Plan and to
 establish, amend and rescind rules and regulations for the
 administration of the Plan, and all such interpretations, rules and
 regulations shall be conclusive and binding on all persons, provided,
 however, that the Committee shall not exercise such authority in a
 manner adversely and significantly affecting rights previously granted
 unless the action taken is required to comply with any applicable law
 or regulation.

 4.  EFFECTIVE DATE AND TERM OF PLAN.

     The Plan shall become effective on July 20, 1988, the date of its
 approval by the Board of Directors of the Corporation.  The Plan shall
 terminate ten years after it becomes effective, unless terminated
 sooner by action of the Board of Directors.  No further grants may be
 made under the Plan after its termination, but the termination of the
 Plan shall not affect the rights of any participant under, or the
 authority of the Committee with respect to, any grants made prior to
 termination.

 5.  SHARES SUBJECT TO THE PLAN.

     Subject to adjustment as provided in paragraph 7 hereof, the
 aggregate number of shares of common stock of the Corporation with
 respect to which stock appreciation rights may be granted under the
 Plan shall not exceed 25,000.  Whenever a stock appreciation right
 granted under the Plan can no

                                     -2-

 longer under any circumstances be exercised, the shares, if any, then
 remaining subject to such stock appreciation right shall thereupon be
 released from such stock appreciation right and shall thereafter be
 available for additional grants of stock appreciation rights under the
 Plan.

 6.  STOCK APPRECIATION RIGHTS.

     (a)  Grants.  Stock appreciation rights entitling the grantee to
 receive cash equal to the sum of (i) the appreciation in value of and
 (ii) the value of the reinvested cash dividends which would have been
 paid with respect to a stated number of shares of common stock of the
 Corporation between the date of grant and the date of exercise (the
 "hypothetical reinvested cash dividends") may be granted from time to
 time to such officers and other key employees of the Corporation and
 its subsidiaries as may be selected by the Committee.

     (b)  Terms of Grant.  Stock appreciation rights shall be
 exercisable in whole or in such installments and at such times as may
 be determined by the Committee, provided that no stock appreciation
 right shall be exercisable more than twenty years after the date of
 grant.  The Committee may at the time of grant or at any time
 thereafter impose such additional terms and conditions on the exercise
 of stock appreciation rights as it deems necessary or desirable for
 compliance with Section 16(a) or 16(b) of the Securities Exchange Act
 of 1934 and the rules and regulations thereunder.
<PAGE>
     (c)   Termination of Employment or Death.  If a grantee ceases to
 be employed by the Corporation and any of its subsidiaries for any
 reason other than death or attaining his Retirement Date, any stock
 appreciation right held by such grantee may be exercised for a period
 ending on the earlier of the 90th day following the date of such
 cessation of employment

                                     -3-

 or the date of expiration of such stock appreciation right, but only
 with respect to that number of shares of common stock for which such
 right was exercisable immediately prior to the date of cessation of
 employment.

     If a grantee ceases to be employed by the Corporation or any of its
 subsidiaries by reason of death prior to his Retirement Date, or dies
 within 90 days after termination of his employment by the Corporation
 or any of its subsidiaries prior to his having attained his Retirement
 Date, any stock appreciation right held by such grantee may be
 exercised, with respect to all or any part of the common stock of the
 Corporation with respect to which such stock appreciation right was
 exercisable by the grantee immediately prior to his death, for a period
 ending on the first anniversary of the date of such grantee's death.

     If a grantee attains his Retirement Date, any stock appreciation
 right held by such grantee may be exercised for a period ending on the
 second anniversary of such Retirement Date, but only with respect to
 that number of shares of common stock for which such right was
 exercisable immediately prior to the date of cessation of employment.

     Notwithstanding any other provision of this Section 6(c), no stock
 appreciation right shall be exercisable after the first to occur of (1)
 the date specified in Section 6(b) or (2) the date specified by the
 Committee in the grant evidencing such rights.

      For purposes of this Plan, the term "Retirement Date" shall mean
 the date on which the grantee's employment with the Corporation (and
 any parent or subsidiary of the Corporation) terminates (including
 termination because of death) if the Optionee had then attained age 55
 and completed ten calendar years of service with the Corporation (or
 any parent or subsidiary of the Corporation).

                                     -4-

     (d)  Payment on Exercise.  Upon exercise of a stock appreciation
 right the grantee shall be paid within five business days an amount in
 cash equal to the sum of (i) the amount by which the fair market value
 of one share of the Corporation's common stock on the date of exercise
 exceeds the date of grant value thereof multiplied by the number of
 shares in respect of which the stock appreciation right is being
 exercised and (ii) the value of the hypothetical reinvested cash
 dividends associated therewith.  The value of the hypothetical
 reinvested cash dividends associated with a share in respect of which
 the stock appreciation right is being exercised (the "exercised share")
 shall be equal to the fair market value on the date of exercise of the
 number of additional shares (or fraction thereof) of the Company's
 common stock the grantee would have owned if it is assumed (1) that
<PAGE>
 cash dividends which would have been paid with respect to the exercised
 share if the exercised share had been outstanding from the time of
 grant had been paid in cash to the grantee and then immediately
 reinvested by the grantee in the Company's common stock at the fair
 market value thereof on the applicable dividend payment date, and (2)
 that, once assumed issued, hypothetical shares resulting from assumed
 dividend reinvestment themselves paid cash dividends (at the same time
 and in the same amount as shares of the Corporation's outstanding
 common stock) which were reinvested in a similar manner.

     For purposes of this paragraph, the fair market value of a share of
 common stock of the Corporation means:

               (A)  The mean between the high and the low prices at
          which the common stock of the Corporation was traded if the
          common 

                                     -5-

          stock of the Corporation was then listed for trading on a
          national or regional securities exchange; or

               (B)  The mean between the published bid and asked prices
          of the common stock of the Corporation if the common stock of
          the Corporation was then traded on a bona fide over-the
          -counter market; or

               (C)  If the common stock of the Corporation was not
          traded on an exchange or on a bona fide over-the-counter
          market, a value determined by an appraiser selected by the 
          Committee.

 In the event that the date of the exercise of a stock appreciation
 right is a date on which there is no trading of the common stock of the
 Corporation on a national or regional securities exchange or is a date
 for which there is no published bid and asked prices if the stock is
 traded on the over-the-counter market, such fair market value shall be
 determined by referring to the next preceding business day on which
 trading occurs or on which published prices are available.

     (e)  Additional Terms and Conditions.  The agreement or instrument
 evidencing the grant of stock appreciation rights may contain such
 other terms, provisions and conditions not inconsistent with the Plan
 as may be determined by the Committee in its sole discretion.

 7.  ADJUSTMENTS FOR CHANGES IN CAPITALIZATION, ETC.

     Stock appreciation rights shall be subject to adjustment by the
 Committee in its sole discretion as to the number, kind and date of
 grant value of shares or other consideration subject to such grants in
 the event of changes in the outstanding common stock by reason of stock
 dividends, stock splits, recapitalizations, reorganizations, mergers,
 consolidations,

                                     -6-
<PAGE>
 combinations, exchanges or other relevant changes in corporate
 structure or capitalization occurring after the date of the grant of
 any stock appreciation right, provided that if the Corporation shall
 change its common stock into a greater or lesser number of shares
 through a stock dividend, stock split-up, or combination of shares,
 outstanding rights shall be adjusted proportionately, consistent with
 existing law and regulation, to prevent inequitable results.

 8.  EFFECT OF LIQUIDATION, MERGER, CONSOLIDATION OR OTHER EVENTS.

     Nothing contained in the Plan of in any stock appreciation right
 granted under the Plan shall in any way prohibit the Corporation from
 merging with or consolidating into another corporation, or from selling
 or transferring all or substantially all of its assets, or from
 distributing all or substantially all of its assets to its stockholders
 in liquidation, or from dissolving and terminating its corporate
 existence; and in any such event, all outstanding stock appreciation
 rights granted under the Plan shall be deemed to have been exercised at
 the time of any such merger, consolidation, sale or transfer of assets,
 liquidation, or dissolution, except to the extent that any agreement or
 undertaking of any party to such merger, consolidation, or sale or
 transfer of assets, or any plan pursuant to which such liquidation or
 dissolution is effected, shall make specific provision to continue such
 stock appreciation rights and the rights of such person or persons
 entitled to exercise such stock appreciation rights.

 9.  AMENDMENT AND TERMINATION OF PLAN.

     The Plan may be amended or terminated by the Board of Directors of
 the Corporation in any respect, provided, however, that the Board
 shall not exercise such authority in a manner adversely and
 significantly affecting rights previously granted unless the action
 taken is required to comply with any applicable law or regulation.

                                     -7-

 10.  MISCELLANEOUS.

     (a)  No Right to a Grant.  Neither the adoption of the Plan nor any
 action of the Board of Directors or of the Committee shall be deemed to
 give any employee any right to be selected as a participant or to be
 granted a stock appreciation right.

     (b)  Rights as Stockholder.  No person shall have any rights as a
 stockholder of the Corporation with respect to any shares covered by a
 stock appreciation right.

     (c)  Employment.  Nothing contained in this Plan shall be deemed to
 confer upon any employee any right of continued employment with the
 Corporation or any of its subsidiaries or to limit or diminish in any
 way the right of the Corporation or any such subsidiary to terminate
 his or her employment at any time with or without cause.

     (d)  Taxes.  the Corporation shall be entitled to deduct from any
 payment under the Plan the amount of any tax required by law to be
 withheld with respect to such payment or may require any participant to
 pay such amount to the Corporation prior to and as a condition of
 making such payment.
<PAGE>
     (e)  Nontransferability.  No stock appreciation right shall be
 transferable except by will or the laws of descent and distribution.
 During the holder's lifetime, stock appreciation rights shall be
 exercisable only by such holder.

 11.  CHANGE IN CONTROL.

     (a)  Definition of "Change in Control."  For purposes of the Plan,
 a "Change in Control" means the happening of any of the following
 events:
          (i)  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

                                     -8-

     promulgated under the Exchange Act) of 20% or more of either (A)
     the then outstanding shares of common stock of the Corporation (the
     "Outstanding Corporation Common Stock") or (B) 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: (1) 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, (2) any acquisition by the
     Corporation, (3) any acquisition by any employee benefit plan (or
     related trust) sponsored or maintained by the Corporation or any
     entity controlled by the Corporation, (4) any acquisition pursuant
     to a transaction which complies with clauses (A), (B), and (C) of
     paragraph (iii) of this Section 11(a), (5) except as provided in
     paragraphs (iv) and (v), any acquisition by any of the Woodson
     Entities or any of the Smith Entities, or (6) 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 (6) shall not apply to any acquisition of
     Outstanding Corporation Common Stock or Outstanding Corporation
     Voting Securities not described in clauses (1), (2), (3), (4), or
     (5) of this paragraph (i) by the Person acquiring such shares which
     occurs after such Person had become the beneficial owner of 20%

                                     -9-

     or more of either the Outstanding Corporation Common Stock or
     Outstanding Corporation Voting Securities by reason of share
     purchases by the Corporation; or (ii)  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
     nomination for election by the Corporation's shareholders, was
<PAGE>
     approved by a vote of at least a majority of those individuals who
     are members of the Board and who were also members of the Incumbent
     Board (or deemed to be such pursuant to this proviso) shall be
     deemed to be and shall be considered as though such individual were
     a member of the Incumbent Board, but provided, further, that any
     such individual whose initial assumption of office occurs as a
     result of either an actual or threatened election 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 (iii)  Consummation of a reorganization, merger
     or consolidation, 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 Corporate
     Transaction pursuant to which (A) all or substantially all

                                  -10-

     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,
     (B) 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 (C) individuals who were members of the Incumbent
     Board will constitute at least a majority of the members of
     the board of directors of the Resulting Corporation; or

                                     -11-

          (iv)  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
<PAGE>
     Corporation; or (v)  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 (vi)  The approval by the shareholders of the

 of the foregoing or any charitable trust or foundation to which any of
 the foregoing transfers or may transfer securities of the Corporation

     For purposes of this Section 11(a), the term "Smith Entities" shall
 mean David B. Smith and Katherine S. Smith, members of their respective
 families and their respective descendants (the "Smith Family"), heirs
 or legatees of any of the Smith Family members, transferees by will,

 effect on the date of this Plan.

     (b)  Effects of Change in Control.
<PAGE>
          (i)  In the event of a Change in Control,

                                     -13-

               (A)  all stock appreciation rights ("SARs") outstanding
          on the date on which such Change in Control has occurred (the
          "Change in Control Date") shall, to the extent not then
          exercisable or vested, immediately become exercisable in full,
          and

               (B)  each grantee may elect, with respect to each SAR
          held by such grantee on the Change in Control Date (the
          grantee's "Election Right"), to surrender such SAR for an
          immediate lump sum cash payment in an amount equal to the
          product of (1) the number of shares of common stock of the
          Corporation ("Shares") then subject to the SAR as to which the
          election is being exercised, multiplied by (2) the excess, if
          any, of (a) the greater of (i) the Change in Control Price or
          (ii) the highest Fair Market Value of a Share on any day in
          the 60-day period ending on the Change in Control Date, over
          (b) the date of grant value of such SAR.  Upon exercise of a
          grantee's Election Right, the value of all hypothetical
          reinvested cash dividends associated with such SAR shall also
          be determined by the greater of (i) the Change in Control
          Price or (ii) the highest Fair Market Value of a Share on any
          day in the 60-day period ending on the Change in Control Date.
          For purposes of this Section 11(b), 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 11(a)(iii), the highest price per Share
          paid in such tender or exchange offer or Corporate
          Transaction.  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

                                     -14-

          other noncash consideration shall be determined in the sole
          discretion of the Committee.

          (ii)  The exercise of an Election Right must be in writing,
     specify the  SAR or SARs and the number of Shares as to which the
     election is being exercised, and be delivered to the Secretary of
     the Corporation 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 Corporation's home office on or before the
     60th day following the Change in Control Date.

          (iii)  All payments due an grantee pursuant to the provisions
     of this Section 11(b) shall be made by the Corporation on or before
     the first to occur of (A) the date provided in this Plan for
     payment upon exercise of an SAR and (B) the 5th business day
     following the date on which the grantee's election has been
     delivered to the Corporation pursuant to Section 11(b)(ii).

          (iv)  Notwithstanding any other provision of this Section
     11(b), if the grant or the exercise of a grantee's Election Right
<PAGE>
     or payment of cash provided for in this Section 11(b)would make a
     Change in Control transaction ineligible for pooling-of-interests
     accounting treatment under APB No. 16, that, but for the nature of
     such grant or exercise of Election Rights, would otherwise be
     eligible for such pooling-of-interests accounting treatment, the
     Committee shall have the right and authority to modify, eliminate,
     or terminate the Election Right to the extent necessary to preserve
     such pooling-of-interests accounting treatment.

                  1988 MANAGEMENT INCENTIVE PLAN

                     As amended March 4, 1999


                 WAUSAU-MOSINEE PAPER CORPORATION
                  1988 MANAGEMENT INCENTIVE PLAN


 1.  PURPOSE.

     The purpose of the Wausau-Mosinee Paper Corporation 1988 Management
 Incentive Plan (the "Plan") is to attract and retain outstanding
 individuals as management employees of Wausau-Mosinee Paper Corporation
 (the "Corporation") and its subsidiaries, and to furnish incentives to
 such individuals through rewards based upon the performance of the
 common stock of the Corporation.  To this end, the Committee
 hereinafter designated may grant stock appreciation rights to
 management employees of the Corporation and its subsidiaries, on the
 terms and subject to the conditions set forth in this Plan.

 2.  PARTICIPANTS.

     Participants in the Plan shall consist of such management employees
 of the Corporation and its subsidiaries as the Committee in its sole
 discretion may select from time to time to receive stock appreciation
 rights.

 3.  ADMINISTRATION OF THE PLAN.

     The Plan shall be administered by a Committee (the "Committee") of
 at least three members appointed by the Board of Directors of the
 Corporation from among its members.  No person shall be appointed a
 member of the Committee if, during the one year prior to the date on
 which such person's service as a member of the Committee is to
 commence, such person was granted or awarded equity securities of the
 Corporation (within the meaning of Securities and Exchange Commission
 Rule 16a-1(d)) under the Plan or any other plan of the Corporation or
 any subsidiary of the Corporation.  Subject to the provisions of the
<PAGE>
                                     -1-

 Plan, the Committee shallhave authority (i) to determine which
 employees of the Corporation and its subsidiaries shall be eligible for
 participation in the plan; (ii) to select employees to receive grants
 under the Plan; (iii) to determine the number of stock appreciation
 rights subject to the grant, the time and conditions of exercise or
 vesting, the fair market value of the common stock of the Corporation
 for purposes of the Plan, and all other terms and conditions of any
 grant; and (iv) to prescribe the form of agreement, certificate or
 other instrument evidencing the grant.  The Committee shall also have
 authority to interpret the Plan and to establish, amend and rescind
 rules and regulations for the administration of the Plan, and all such
 interpretations, rules and regulations shall be conclusive and binding
 on all persons, provided, however, that the Committee shall not
 exercise such authority in a manner adversely and significantly
 affecting rights previously granted unless the action taken is
 required to comply with any applicable law or regulation.

 4.  EFFECTIVE DATE AND TERM OF PLAN.

     The Plan shall become effective on August 15, 1988, the date of its
 approval by the Board of Directors of the Corporation.  The Plan shall
 terminate ten years after it becomes effective, unless terminated
 sooner by action of the Board of Directors.  No further grants may be
 made under the Plan after its termination, but the termination of the
 Plan shall not affect the rights of any participant under, or the
 authority of the Committee with respect to, any grants made prior to
 termination.

 5.  SHARES SUBJECT TO THE PLAN.

     Subject to adjustment as provided in paragraph 7 hereof, the
 aggregate number of shares of common stock of the Corporation with
 respect to which stock appreciation rights may be granted under the

                                     -2-

 Plan shall not exceed 75,000.  Whenever a stock appreciation right
 granted under the Plan can no longer under any circumstances be
 exercised, the shares, if any, then remaining subject to such stock
 appreciation right shall thereupon be released from such stock
 appreciation right and shall thereafter be available for additional
 grants of stock appreciation rights under the Plan.

 6.  STOCK APPRECIATION RIGHTS.

     (a)  Grants.  Stock appreciation rights entitling the grantee to
 receive cash equal to the sum of (i) the appreciation in value of and
 (ii) the value of the reinvested cash dividends which would have been
 paid with respect to a stated number of shares of common stock of the
 Corporation between the date of grant and the date of exercise (the
 "hypothetical reinvested cash dividends") may be granted from time to
 time to such officers and other key employees of the Corporation and
 its subsidiaries as may be selected by the Committee.
<PAGE>
     (b)  Terms of Grant.  Stock appreciation rights shall be
 exercisable in whole or in such installments and at such times and
 subject to the attainment of such performance goals as may be
 determined by the Committee, provided that no stock appreciation right
 shall be exercisable more than twenty years after the date of grant.
 The Committee may at the time of grant or at any time thereafter impose
 such additional terms and conditions on the exercise of stock
 appreciation rights as it deems necessary or desirable for compliance
 with Section 16(a) or 16(b) of the Securities Exchange Act of 1934 and
 the rules and regulations thereunder.

     (c)   Termination of Employment or Death.  If a grantee ceases to
 be employed by the Corporation and any of its subsidiaries for any
 reason other than death or attaining his Retirement Date, any stock
 appreciation right held by such grantee may be exercised for a period

                                     -3-

 ending on the earlier of the 90th day following the date of such
 cessation of employment or the date of expiration of such stock
 appreciation right, but only with respect to that number of shares of
 common stock for which such right was exercisable immediately prior to
 the date of cessation of employment.

     If a grantee ceases to be employed by the Corporation or any of its
 subsidiaries by reason of death prior to his Retirement Date, or dies
 within 90 days after termination of his employment by the Corporation
 or any of its subsidiaries prior to his having attained his Retirement
 Date, any stock appreciation right held by such grantee may be
 exercised, with respect to all or any part of the common stock of the
 Corporation with respect to which such stock appreciation right was
 exercisable by the grantee immediately prior to his death, for a period
 ending on the first anniversary of the date of such grantee's death.

     If a grantee attains his Retirement Date, any stock appreciation
 right held by such grantee may be exercised for a period ending on the
 second anniversary of such Retirement Date, but only with respect to
 that number of shares of common stock for which such right was
 exercisable immediately prior to the date of cessation of employment.

     Notwithstanding any other provision of this Section 6(c), no stock
 appreciation right shall be exercisable after the first to occur of (1)
 the date specified in Section 6(b) or (2) the date specified by the
 Committee in the grant evidencing such rights.

      For purposes of this Plan, the term "Retirement Date" shall mean
 the date on which the grantee's employment with the Corporation (and
 any parent or subsidiary of the Corporation) terminates (including
 termination because of death) if the Optionee had then attained age 55
 

                                     -4-

 and completed ten calendar years of service with the Corporation (or
 any parent or subsidiary of the Corporation).
<PAGE>
     (d)  Payment on Exercise.  Upon exercise of a stock appreciation
 right the grantee shall be paid within five business days an amount in
 cash equal to the sum of (i) the amount by which the fair market value
 of one share of the Corporation's common stock on the date of exercise
 exceeds the date of grant value thereof multiplied by the number of
 shares in respect of which the stock appreciation right is being
 exercised and (ii) the value of the hypothetical reinvested cash
 dividends associated therewith.  The value of the hypothetical
 reinvested cash dividends associated with a share in respect of which
 the stock appreciation right is being exercised (the "exercised share")
 shall be equal to the fair market value on the date of exercise of the
 number of additional shares (or fraction thereof) of the Corporation's
 common stock the grantee would have owned if it is assumed (1) that
 cash dividends which would have been paid with respect to the exercised
 share if the exercised share had been outstanding from the time of
 grant had been paid in cash to the grantee and then immediately
 reinvested by the grantee in the Corporation's common stock at the fair
 market value thereof on the applicable dividend payment date, and (2)
 that, once assumed issued, hypothetical shares resulting from assumed
 dividend reinvestment themselves paid cash dividends (at the same time
 and in the same amount as shares of the Corporation's outstanding
 common stock) which were reinvested in a similar manner.

     For purposes of this paragraph, the fair market value of a share of
 common stock of the Corporation means:

                                     -5-

          (A)  The mean between the high and the low prices at which the
     common stock of the Corporation was traded if the common stock of
     the Corporation was then listed for trading on a national or
     regional securities exchange; or

          (B)  The mean between the published bid and asked prices of
     the common stock of the Corporation if the common stock of the
     Corporation was then traded on a bona fide over-the-counter market;
     or (C)  If the common stock of the Corporation was not traded on an
     exchange or on a bona fide over-the-counter market, a value
     determined by an appraiser selected by the Committee.

 In the event that the date of the exercise of a stock appreciation
 right is a date on which there is no trading of the common stock of the
 Corporation on a national or regional securities exchange or is a date
 for which there is no published bid and asked prices if the stock is
 traded on the over-the-counter market, such fair market value shall be
 determined by referring to the next preceding business day on which
 trading occurs or on which published prices are available.

     (e)  Additional Terms and Conditions.  The agreement or instrument
 evidencing the grant of stock appreciation rights may contain such
 other terms, provisions and conditions not inconsistent with the Plan
 as may be determined by the Committee in its sole discretion.
<PAGE>
 7.  ADJUSTMENTS FOR CHANGES IN CAPITALIZATION, ETC.

     Stock appreciation rights shall be subject to adjustment by the
 Committee in its sole discretion as to the number, kind and date of
 grant value of shares or other consideration subject to such grants in
 the event of changes in the outstanding common stock by reason of stock

                                     -6-

 dividends, stock splits, recapitalizations, reorganizations, mergers,
 consolidations, combinations, exchanges or other relevant changes in
 corporate structure or capitalization occurring after the date of the
 grant of any stock appreciation right, provided that if the Corporation
 shall change its common stock into a greater or lesser number of shares
 through a stock dividend, stock split-up, or combination of shares,
 outstanding rights shall be adjusted proportionately, consistent with
 existing law and regulation, to prevent inequitable results.

 8.  EFFECT OF LIQUIDATION, MERGER, CONSOLIDATION OR OTHER EVENTS.

     Nothing contained in the Plan or in any stock appreciation right
 granted under the Plan shall in any way prohibit the Corporation from
 merging with or consolidating into another corporation, or from selling
 or transferring all or substantially all of its assets, or from
 distributing all or substantially all of its assets to its stockholders
 in liquidation, or from dissolving and terminating its corporate
 existence; and in any such event, all outstanding stock appreciation
 rights granted under the Plan shall be deemed to have been exercised,
 to the extent then exercisable by the grantee, at the time of any such
 merger, consolidation, sale or transfer of assets, liquidation, or
 dissolution, except to the extent that any agreement or undertaking of
 any party to such merger, consolidation, or sale or transfer of assets,
 or any plan pursuant to which such liquidation or dissolution is
 effected, shall make specific provision to continue such stock
 appreciation rights and the rights of such person or persons entitled
 to exercise such stock appreciation rights.

 9.  AMENDMENT AND TERMINATION OF PLAN.

     The Plan may be amended or terminated by the Board of Directors of
 the Corporation in any respect, provided, however, that the Board shall
 not exercise such authority in a manner adversely and significantly

                                     -7-

 affecting rights previously granted unless the action taken is required
 to comply with any applicable law or regulation.

 10.  MISCELLANEOUS.

     (a)  No Right to a Grant.  Neither the adoption of the Plan nor any
 action of the Board of Directors or of the Committee shall be deemed to
 give any employee any right to be selected as a participant or to be
 granted a stock appreciation right.
<PAGE>
     (b)  Rights as Stockholder.  No person shall have any rights as a
 stockholder of the Corporation with respect to any shares covered by a
 stock appreciation right.

     (c)  Employment.  Nothing contained in this Plan shall be deemed to
 confer upon any employee any right of continued employment with the
 Corporation or any of its subsidiaries or to limit or diminish in any
 way the right of the Corporation or any such subsidiary to terminate
 his or her employment at any time with or without cause.

     (d)  Taxes.  The Corporation shall be entitled to deduct from any
 payment under the Plan the amount of any tax required by law to be
 withheld with respect to such payment or may require any participant to
 pay such amount to the Corporation prior to and as a condition of
 making such payment.

     (e)  Nontransferability.  No stock appreciation right shall be
 transferable except by will or the laws of descent and distribution.
 During the holder's lifetime, stock appreciation rights shall be
 exercisable only by such holder.

 11.  CHANGE OF CONTROL.

     (a)  Definition of "Change in Control."  For purposes of the Plan,
 a "Change in Control" means the happening of any of the following
 events:

                                     -8-

          (i)  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 (A) the then outstanding shares of common stock of the
     Corporation (the "Outstanding Corporation Common Stock") or (B)
     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: (1) 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, (2)
     any acquisition by the Corporation, (3) any acquisition by any
     employee benefit plan (or related trust) sponsored or maintained by
     the Corporation or any entity controlled by the Corporation, (4)
     any acquisition pursuant to a transaction which complies with
     clauses (A), (B), and (C) of paragraph (iii) of this Section 11(a),
     (5) except as provided in paragraphs (iv) and (v), any acquisition
     by any of the Woodson Entities or any of the Smith Entities, or (6)
     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 (6) shall not
     apply to any acquisition of Outstanding Corporation Common Stock
<PAGE>
                                     -9-

     or Outstanding Corporation Voting Securities not described in
     clauses (1), (2), (3), (4), or (5) of this paragraph (i) 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

          (ii)  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 nomination for election by the
     Corporation's shareholders, was approved by a vote of at least a
     majority of those individuals who are members of the Board and who
     were also members of the Incumbent Board (or deemed to be such
     pursuant to this proviso) shall be deemed to be and shall be
     considered as though such individual were a member of the Incumbent
     Board, but provided, further, that any such individual whose
     initial assumption of office occurs as a result of either an actual
     or threatened election 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

                                     -10-

          (iii)  Consummation of a reorganization, merger or
     consolidation, 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 Corporate
     Transaction pursuant to which (A) all or substantially all
     of 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,
     (B) 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,
<PAGE>
     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

                                   -11-

     ownership existed with respect to the Corporation prior to the
     Corporate Transaction, and (C) individuals who were members of the
     Incumbent Board will constitute at least a majority of the members
     of the board of directors of the Resulting Corporation; or

          (iv)  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 (v)  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 (vi)  The approval by the shareholders of the

 executor or administrator of any estate of any of the foregoing), 

                                     -12-

 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).

      For purposes of this Section 11(a), the term "Smith Entities"
 shall mean David B. Smith and Katherine S. Smith, members of their
 respective families and their respective descendants (the "Smith
 Family"), heirs or legatees of any of the Smith Family members,
 transferees by will, laws of descent or distribution or by operation of
 law of any of the foregoing (including of any such transferees)
<PAGE>
 (including any executor or administrator of any estate of any of the
 foregoing), any trust established by either of David B. Smith or

                                     -13-

     For purposes of this Section 11(a), the terms "Affiliate" and
 "Associate" shall have the meanings ascribed to such terms in Rule
 12b-2 of the General Rules and Regulations under the Exchange Act as in
 effect on the date of this Plan.

     (b)  Effects of Change in Control.

     (i)  In the event of a Change in Control,

          (A)  all stock appreciation rights ("SARs") outstanding on the
     date on which such Change in Control has occurred (the "Change in
     Control Date") shall, to the extent not then exercisable or vested,
     immediately become exercisable in full, and
          (B)  each grantee may elect, with respect to each SAR held by
     such grantee on the Change in Control Date (the grantee's "Election
     Right"), to surrender such SAR for an immediate lump sum cash
     payment in an amount equal to the product of (1) the number of
     shares of common stock of the Corporation ("Shares") then subject
     to the SAR as to which the election is being exercised, multiplied
     by (2) the excess, if any, of (a) the greater of (i) the Change in
     Control Price or (ii) the highest Fair Market Value of a Share on
     any day in the 60-day period ending on the Change in Control Date,
     over (b) the date of grant value of such SAR.  Upon exercise of a
     grantee's Election Right, the value of all hypothetical reinvested
     cash dividends associated with such SAR shall also be determined by
     the greater of (i) the Change in Control Price or (ii) the highest
     Fair Market Value of a Share on any day in the 60-day period ending
     on the Change in Control Date.  For purposes of this Section
     11(b), 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 11(a)(iii), the highest price

                                     -14-

     per Share paid in such tender or exchange offer or Corporate
     Transaction.  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 exercise of an Election Right must be in writing,
<PAGE>
     specify the SAR or SARs and the number of Shares as to which the
     election is being exercised, and be delivered to the Secretary of
     the Corporation 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 Corporation's home office on or before the
     60th day following the Change in Control Date.

          (iii)  All payments due an grantee pursuant to the provisions
     of this Section 11(b) shall be made by the Corporation on or before
     the first to occur of (A) the date provided in this Plan for
     payment upon exercise of an SAR and (B) the 5th business day
     following the date on which the grantee's election has been
     delivered to the Corporation pursuant to Section 11(b)(ii).

          (iv)  Notwithstanding any other provision of this Section
     11(b), if the grant or the exercise of a grantee's Election Right
     or payment of cash provided for in this Section 11(b) would make a
     Change in Control transaction ineligible for pooling-of-interests
     accounting treatment under APB No. 16, that, but for the nature of
     such grant or exercise of Election Rights, would otherwise be
     eligible for such pooling-of-interests accounting treatment, the
     Committee shall have the right and authority to modify, eliminate,

                                     -15-

     or terminate the Election Right to the extent necessary to preserve
     such pooling-of-interests accounting treatment.

                                     -16-

                 WAUSAU-MOSINEE PAPER CORPORATION
                1990 STOCK APPRECIATION RIGHTS PLAN

                     As amended March 4, 1999

                 WAUSAU-MOSINEE PAPER CORPORATION
                1990 STOCK APPRECIATION RIGHTS PLAN

 1.  PURPOSE.

     The purpose of the Wausau-Mosinee Paper Corporation 1990 Stock
 Appreciation Rights Plan (the "Plan") is to attract and retain
 outstanding individuals as officers and key employees of Wausau-Mosinee
 Paper Corporation (the "Corporation") and its subsidiaries, and to
 furnish incentives to such individuals through rewards based upon the
 performance of the common stock of the Corporation.  To this end, the
 Committee hereinafter designated may grant stock appreciation rights to
 officers and other key employees of the Corporation and its
 subsidiaries, on the terms and subject to the conditions set forth in
 this Plan.
<PAGE>
 2.  PARTICIPANTS.

     Participants in the Plan shall consist of such officers and other
 key employees of the Corporation and its subsidiaries as the Committee
 in its sole discretion may select from time to time to receive stock
 appreciation rights.

 3.  ADMINISTRATION OF THE PLAN.

     The Plan shall be administered by a Committee (the "Committee") of
 at least three members appointed by the Board of Directors of the
 Corporation from among its members.  No person shall be appointed a
 member of the Committee if, during the one year prior to the date on
 which such person's service as a member of the Committee is to
 commence, such person was granted or awarded equity securities of the
 Corporation (within the meaning of Securities and Exchange Commission
 Rule 16a-1(d)) under the Plan or any other plan of the Corporation or
 any subsidiary of the Corporation.  Subject to the provisions of the
 Plan, the Committee shall have authority (i) to determine which

                                     -1-

 employees of the Corporation and its subsidiaries shall be eligible for
 participation in the Plan; (ii) to select employees to receive grants
 under the Plan; (iii) to determine the number of stock appreciation
 rights subject to the grant, the time and conditions of exercise or
 vesting, the fair market value of the common stock of the Corporation
 for purposes of the Plan, and all other terms and conditions of any
 grant; and (iv) to prescribe the form of agreement, certificate or
 other instrument evidencing the grant.  The Committee shall also have
 authority to interpret the Plan and to establish, amend and rescind
 rules and regulations for the administration of the Plan, and all such
 interpretations, rules and regulations shall be conclusive and
 binding on all persons, provided, however, that the Committee shall not
 exercise such authority in a manner adversely and significantly
 affecting rights previously granted unless the action taken is required
 to comply with any applicable law or regulation.

 4.  EFFECTIVE DATE AND TERM OF PLAN.

     The Plan shall become effective on July 24, 1990, the date of its
 approval by the Board of Directors of the Corporation.  The Plan shall
 terminate ten years after it becomes effective, unless terminated
 sooner by action of the Board of Directors.  No further grants may be
 made under the Plan after its termination, but the termination of the
 Plan shall not affect the rights of any participant under, or the
 authority of the Committee with respect to, any grants made prior to
 termination.

 5.  SHARES SUBJECT TO THE PLAN.

     Subject to adjustment as provided in paragraph 7 hereof, the
 aggregate number of shares of common stock of the Corporation with
 respect to which stock appreciation rights may be granted under the
 Plan shall not exceed 250,000.  Whenever a stock appreciation right
<PAGE>
                                     -2-

 granted under the Plan can no longer under any circumstances be
 exercised, the shares, if any, then remaining subject to such stock
 appreciation right shall thereupon be released from such stock
 appreciation right and shall thereafter be available for additional
 grants of stock appreciation rights under the Plan.

 6.  STOCK APPRECIATION RIGHTS.

     (a)  Grants.  Stock appreciation rights entitling the grantee to
 receive cash equal to the sum of (i) the appreciation in value of and
 (ii) the value of the reinvested cash dividends which would have been
 paid with respect to a stated number of shares of common stock of the
 Corporation between the date of grant and the date of exercise (the
 "hypothetical reinvested cash dividends") may be granted from time to 
 time to such officers and other key employees of the Corporation and
 its subsidiaries as may be selected by the Committee.

     (b)  Terms of Grant.  Stock appreciation rights shall be
 exercisable in whole or in such installments and at such times as may
 be determined by the Committee, provided that no stock appreciation
 right shall be exercisable more than twenty years after the date of
 grant.  The Committee may at the time of grant or at any time
 thereafter impose such additional terms and conditions on the exercise
 of stock appreciation rights as it deems necessary or desirable for
 compliance with Section 16(a) or 16(b) of the Securities Exchange Act
 of 1934 and the rules and regulations thereunder.

     (c)  Termination of Employment or Death.  If a grantee ceases to be
 employed by the Corporation and any of its subsidiaries for any reason
 other than death or attaining his Retirement Date, any stock
 appreciation right held by such grantee may be exercised for a period
 ending on the earlier of the 90th day following the date of such

                                     -3-

 cessation of employment or the date of expiration of such stock
 appreciation right, but only with respect to that number of shares of
 common stock for which such right was exercisable immediately prior to
 the date of cessation of employment.

      If a grantee ceases to be employed by the Corporation or any of
 its subsidiaries by reason of death prior to his Retirement Date, or
 dies within 90 days after termination of his employment by the
 Corporation or any of its subsidiaries prior to his having attained his
 Retirement Date, any stock appreciation right held by such grantee may
 be exercised, with respect to all or any part of the common stock of
 the Corporation with respect to which such stock appreciation right was
 exercisable by the grantee immediately prior to his death, for a period
 ending on the first anniversary of the date of such grantee's death.

     If a grantee attains his Retirement Date, any stock appreciation
 right held by such grantee may be exercised for a period ending on the
 second anniversary of such Retirement Date, but only with respect to
 that number of shares of common stock for which such right was
 exercisable immediately prior to the date of cessation of employment.
<PAGE>
     Notwithstanding any other provision of this Section 6(c), no stock
 appreciation right shall be exercisable after the first to occur of (1)
 the date specified in Section 6(b) or (2) the date specified by the
 Committee in the grant evidencing such rights.

      For purposes of this Plan, the term "Retirement Date" shall mean
 the date on which the grantee's employment with the Corporation (and
 any parent or subsidiary of the Corporation) terminates (including
 termination because of death) if the Optionee had then attained age 55
 and completed ten calendar years of service with the Corporation (or
 any parent or subsidiary of the Corporation).

                                     -4-

     (d)  Payment on Exercise.  Upon exercise of a stock appreciation
 right the grantee shall be paid within five business days an amount in
 cash equal to the sum of (i) the amount by which the fair market value
 of one share of the Corporation's common stock on the date of exercise
 exceeds the date of grant value thereof multiplied by the number of
 shares in respect of which the stock appreciation right is being
 exercised and (ii) the value of the hypothetical reinvested cash
 dividends associated therewith.  The value of the hypothetical
 reinvested cash dividends associated with a share in respect of which
 the stock appreciation right is being exercised (the "exercised share")
 shall be equal to the fair market value on the date of exercise of the
 number of additional shares (or fraction thereof) of the Corporation's
 common stock the grantee would have owned if it is assumed (1) that
 cash dividends which would have been paid with respect to the exercised
 share if the exercised share had been outstanding from the time of
 grant had been paid in cash to the grantee and then immediately
 reinvested by the grantee in the Corporation's common stock at the fair
 market value thereof on the applicable dividend payment date, and (2)
 that, once assumed issued, hypothetical shares resulting from assumed
 dividend reinvestment themselves paid cash dividends (at the same time
 and in the same amount as shares of the Corporation's outstanding
 common stock) which were reinvested in a similar manner.

     For purposes of this paragraph, the fair market value of a share
 of common stock of the Corporation means:

          (A)  The mean between the high and the low prices at which the
     common stock of the Corporation was traded if the common stock of
     the Corporation was then listed for trading on a national or
     regional securities exchange; or

                                     -5-

          (B)  The mean between the published bid and asked prices of
     the common stock, of the Corporation if the common stock of the
     Corporation was then traded on a bona fide over-the-counter market;
     or

          (C)  If the common stock of the Corporation was not traded on
     an exchange or on a bona fide over-the-counter market, a value
     determined by an appraiser selected by the Committee.
<PAGE>
 In the event that the date of the exercise of a stock appreciation
 right is a date on which there is no trading of the common stock of the
 Corporation on a national or regional securities exchange or is a date
 for which there is no published bid and asked prices if the stock is
 traded on the over-the-counter market, such fair market value shall be
 determined by referring to the next preceding business day on which
 trading occurs or on which published prices are available.

     (e)  Additional Terms and Conditions.  The agreement or instrument
 evidencing the grant of stock appreciation rights may contain such
 other terms, provisions and conditions not inconsistent with the Plan
 as may be determined by the Committee in its sole discretion.

 7.  ADJUSTMENTS FOR CHANGES IN CAPITALIZATION, ETC.

     Stock appreciation rights shall be subject to adjustment by the
 Committee in its sole discretion as to the number, kind and date of
 grant value of shares or other consideration subject to such grants
 in the event of changes in the outstanding common stock by reason of
 stock dividends, stock splits, recapitalizations, reorganizations,
 mergers, consolidations, combinations, exchanges or other relevant
 changes in corporate structure or capitalization occurring after the
 date of the grant of any stock appreciation right, provided that if the

                                     -6-

 Corporation shall change itscommon stock into a greater or lesser
 number of shares through a stock dividend, stock split-up, or
 combination of shares, outstanding rights shall be adjusted
 proportionately, consistent with existing law and regulation, to
 prevent inequitable results.

 8.  EFFECT OF LIQUIDATION, MERGER, CONSOLIDATION OR OTHER EVENTS.

     Nothing contained in the Plan or in any stock appreciation right
 granted under the Plan shall in any way prohibit the Corporation from
 merging with or consolidating into another corporation, or from selling
 or transferring all or substantially all of its assets, or from
 distributing all or substantially all of its assets to its stockholders
 in liquidation, or from dissolving and terminating its corporate
 existence; and in any such event, all outstanding stock appreciation
 rights granted under the Plan shall be deemed to have been exercised at
 the time of any such merger, consolidation, sale or transfer of assets,
 liquidation, or dissolution, except to the extent that any agreement or
 undertaking of any party to such merger, consolidation, or sale or
 transfer of assets, or any plan pursuant to which such liquidation or
 dissolution is effected, shall make specific provision to continue such
 stock appreciation rights and the rights of such person or persons
 entitled to exercise such stock appreciation rights.

 9.  AMENDMENT AND TERMINATION OF PLAN.

     The Plan may be amended or terminated by the Board of Directors of
 the Corporation in any respect, provided, however, that the Board shall
 not exercise such authority in a manner adversely and significantly
 affecting rights previously granted unless the action taken is required
 to comply with any applicable law or regulation.
<PAGE>
                                     -7-

 10.  MISCELLANEOUS.

     (a)  No Right to a Grant.  Neither the adoption of the Plan nor any
 action of the Board of Directors or of the Committee shall be deemed to
 give any employee any right to be selected as a participant or to be
 granted a stock appreciation right.

     (b)  Rights as Stockholder.  No person shall have any rights as a
 stockholder of the Corporation with respect to any shares covered by a
 stock appreciation right.

     (c)  Employment.  Nothing contained in this Plan shall be deemed to
 confer upon any employee any right of continued employment with the
 Corporation or any of its subsidiaries or to limit or diminish in any
 way the right of the Corporation or any such subsidiary to terminate
 his or her employment at any time with or without cause.

     (d)  Taxes.  the Corporation shall be entitled to deduct from any
 payment under the Plan the amount of any tax required by law to be
 withheld with respect to such payment or may require any participant to
 pay such amount to the Corporation prior to and as a condition of
 making such payment.

     (e)  Nontransferability.  No stock appreciation right shall be
 transferable except by will or the laws of descent and distribution.
 During the holder's lifetime, stock appreciation rights shall be
 exercisable only by such holder.

 11.  CHANGE OF CONTROL.

     (a)  Definition of "Change in Control."  For purposes of the Plan,
 a "Change in Control" means the happening of any of the following
 events:

          (i)  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

                                     -8-

     Rule 13d-3 promulgated under the Exchange Act) of 20% or more of
     either (A) the then outstanding shares of common stock of the
     Corporation (the "Outstanding Corporation Common Stock") or (B) 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: (1) 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, (2)
     any acquisition by the Corporation, (3) any acquisition by any
     employee benefit plan (or related trust) sponsored or maintained by
     the Corporation or any entity controlled by the Corporation, (4)
     any acquisition pursuant to a transaction which complies with

     any increase in the proportionate number of shares of Outstanding
     Corporation Common Stock or Outstanding Corporation Voting

     solely the result of the acquisition of Outstanding Corporation
     Common Stock or Outstanding Corporation Voting Securities by the
     Corporation; provided, however, that this clause (6) shall not
     apply to any acquisition of Outstanding Corporation Common Stock or
     Outstanding Corporation Voting Securities not described in clauses
     (1), (2), (3), (4), or (5) of this paragraph (i) by the Person
     acquiring such shares which occurs after such Person had become the

                                    -9-

     beneficial owner of 20% or more of either the Outstanding
     Corporation Common Stock or Outstanding Corporation Voting

     Corporation's shareholders, was approved by a vote of at least a
     majority of those individuals who are members of the Board and who
     were also members ofthe Incumbent Board (or deemed to be such
     pursuant to this proviso) shall be deemed to be and shall be
     considered as though such individual were a member of the Incumbent
     Board, but provided, further, that any such individual whose
     initial assumption of office occurs as a result of either an actual
     or threatened election 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

     consolidation, 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

     Transaction pursuant to which (A) all or substantially all

                                     -10-

     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,
     (B) 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 (C) individuals who were members of the Incumbent
     Board will constitute at least a majority of the members of the
     board of directors of the Resulting Corporation; or

                                    -11-

          (iv)  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

     the case may be, of the Resulting Corporation; or

           (v)  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

     directors, as the case may be, of the Resulting Corporation; or

 Aytchmonde P. Woodson, Leigh Yawkey Woodson, or Alice Richardson
 Yawkey, whether pursuant to last will or otherwise, any partnership,

 of the foregoing or any Affiliates or Associates of any of the

                                     -12-
<PAGE>
 foregoing or any charitable trust or foundation to which any of the
 foregoing transfers or may transfer securities of the Corporation

 any of the foregoing or any other Person serving any such entity in a
 similar capacity).

     For purposes of this Section 11(a), the term "Smith Entities" shall
 mean David B. Smith and Katherine S. Smith, members of their respective
 families and their respective descendants (the "Smith Family"), heirs

 effect on the date of this Plan.

     (b)  Effects of Change in Control.

     (i)  In the event of a Change in Control,

                                     -13-

          (A)  all stock appreciation rights ("SARs") outstanding on the
     date on which such Change in Control has occurred (the "Change in
     Control Date") shall, to the extent not then exercisable or vested,
     immediately become exercisable in full, and

          (B)  each grantee may elect, with respect to each SAR held by
     such grantee on the Change in Control Date (the grantee's "Election
     Right"), to surrender such SAR for an immediate lump sum cash
     payment in an amount equal to the product of (1) the number of
     shares of common stock of the Corporation ("Shares") then subject
     to the SAR as to which the election is being exercised, multiplied
     by (2) the excess, if any, of (a) the greater of (i) the Change in
     Control Price or (ii) the highest Fair Market Value of a Share on
     any day in the 60-day period ending on the Change in Control Date,
     over (b) the date of grant value of such SAR.  Upon exercise of a
     grantee's Election Right, the value of all hypothetical reinvested
     cash dividends associated with such SAR shall also be determined by
     the greater of (i) the Change in Control Price or (ii) the highest
     Fair Market Value of a Share on any day in the 60-day period ending
     on the Change in Control Date.   For purposes of this Section
     11(b), the "Change in Control Price" shall mean, if the Change in
<PAGE>
     Control is the result of a tender or exchange offer or a Corporate
     Transaction (as defined in Section 11(a)(iii), the highest price
     per Share paid in such tender or exchange offer or Corporate
     Transaction.  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.

                                     -14-

          (ii)  The exercise of an Election Right must be in writing,
     specify the  SAR or SARs and the number of Shares as to which the
     election is being exercised, and be delivered to the Secretary of
     the Corporation 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 Corporation's home office on or before the
     60th day following the Change in Control Date.

          (iii)  All payments due an grantee pursuant to the provisions
     of this Section 11(b) shall be made by the Corporation on or before
     the first to occur of (A) the date provided in this Plan for
     payment upon exercise of an SAR and (B) the 5th business day
     following the date on which the grantee's election has been
     delivered to the Corporation pursuant to Section 11(b)(ii).

          (iv)  Notwithstanding any other provision of this Section
     11(b), if the grant or the exercise of a grantee's Election Right
     or payment of cash provided for in this Section 11(b)would make a
     Change in Control transaction ineligible for pooling-of-interests
     accounting treatment under APB No. 16, that, but for the nature of
     such grant or exercise of Election Rights, would otherwise be
     eligible for such pooling-of-interests accounting treatment, the
     Committee shall have the right and authority to modify, eliminate,
     or terminate the Election Right to the extent necessary to preserve
     such pooling-of-interests accounting treatment.

                     DEFERRED COMPENSATION AGREEMENT


     THIS AGREEMENT, dated July 1, 1994, by and between WAUSAU PAPER
 MILLS COMPANY (herein referred to as the "Corporation") and SAN W.
 ORR, JR., an individual (herein referred to as "Executive").

                       W I T N E S S E T H:

     WHEREAS, the Corporation and Executive entered into a deferred
 compensation agreement dated March 2, 1990 and now desire to amend and
 clarify certain provisions of that agreement;
<PAGE>
     NOW, THEREFORE, the parties agree as follows:

     1.   ELECTION TO DEFER.  Executive may, in his discretion, elect to
 defer all or any cash compensation (specified by amount or percentage
 of such compensation) payable to him by the Corporation from time to
 time for service to the Corporation as an employee by executing an
 election in the form set forth in Exhibit A hereto (herein referred to
 as an "Election") and filing such Election with the secretary of the
 Corporation (herein referred to as the "Secretary").  An Election shall
 be effective with respect to all cash compensation specified on the
 election form filed with the Secretary by Executive which is accrued
 and payable after the date the Election is received by the Secretary
 and until the Election is amended or revoked.  An Election hereunder
 may be amended or revoked at any time by filing a subsequent Election
 with the Secretary.  

                                     -1-

 Such amendment or revocation shall be effective with respect to cash
 compensation accrued and payable on and after receipt of such new
 Election by the Secretary.

     2.   DEFERRED COMPENSATION ACCOUNT.  The Corporation shall maintain
 upon its corporate books a deferred compensation account (herein
 referred to as the "Account") with respect to any compensation deferred
 under this agreement.  As of the first day of each calendar month, the
 Corporation shall make the following adjustments to the Account:  (a)
 Subtract amounts paid from the Account during the immediately preceding
 month; and (b) Add the amount of compensation Executive has elected to
 defer under paragraph 1 which was otherwise payable to Executive during
 the immediately preceding month.  As of the first day of each calendar
 year, the Corporation shall add to the Account simple interest,
 calculated at a rate equal to average of the prime rate published in
 THE WALL STREET JOURNAL on the first business day of each calendar
 quarter in the preceding calendar year, minus one percentage point, on
 the average daily balance in the Account during the preceding year.
 The Account created hereunder shall not represent any specific assets
 of the Corporation, and the Corporation is not obligated by this
 provision to set aside any assets in respect of the Account.

     3.   DISTRIBUTION.  Distribution of the amount reflected in the
 Account shall be made in 5 annual installments with the first
 installment payment to be made within the 60 day period following the
 date on which Executive ceases to be a member of the Board of Directors
 of the Corporation; provided, however, that in the event of a "Change
 in Control" (defined below) or Executive's death, the remaining balance
 in the Account shall be distributed within the 60 day period following
 the date of such event in a single lump sum payment.  The amount of
 
                                     -2-

 each annual installment distribution shall equal the balance in the
 Account on the date set for payment of such installment divided by the
 number of installment distributions remaining within the distribution
 period (including such installment).  Interest shall continue to be
 credited under paragraph 2 during the installment distribution period.
 For purposes of this paragraph 3, a "Change in Control" shall mean:
<PAGE>
          (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
    subparagraph (c) of this paragraph 3, (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

                                     -3-

     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

          (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 nomination for election by the
     Corporation's shareholders, was approved by a vote of at least a
     majority of those individuals who are members of the Board and who
     were also members of the Incumbent Board (or deemed to be such
     pursuant to this proviso) shall be deemed to be and shall be
     considered as though such individual were a member of the Incumbent
     Board, but provided, further, that any such individual whose
     initial assumption of office occurs as a result of either an actual
     or threatened election contest (as such terms are used in Rule
     14a-11 of Regulation 14A promulgated under

                                    -4-

     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

          (c)  Consummation of a reorganization, merger or
     consolidation, 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 Corporate Transaction
     pursuant to which (i) all or substantially all of 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)
     
                                    -5-

     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.

                      WAUSAU-MOSINEE PAPER CORPORATION
                      1991 EMPLOYEE STOCK OPTION PLAN


                          As amended March 4, 1999

                      WAUSAU-MOSINEE PAPER CORPORATION
                      1991 EMPLOYEE STOCK OPTION PLAN
<PAGE>
     Wausau-Mosinee Paper Corporation, a Wisconsin corporation (the
 "Company"), hereby adopts the Wausau-Mosinee Paper Corporation 1991
 Employee Stock Option Plan (the "Plan"), as set forth herein.

     Section 1.  PURPOSE.  The Plan has been adopted for the purpose of
 recognizing and rewarding the job performance of key employees of the
 Company and to enable the Company to attract and retain superior
 management-level employees by increasing the personal interest of all
 such employees in the growth and success of the Company.  It is the
 express intent of the Company that, subject to Section 6(g) hereof, all
 options granted hereunder designated "Incentive Stock Options" shall
 meet the requirements of Section 422 of the Internal Revenue Code of
 1986, as amended (the "Code"), or any successor section or sections.
 It is the further intent of the Company that options granted hereunder
 designated "Non-Qualified Stock Options" shall not meet the 
 requirements of Section 422 of the Code.

     Section 2.  NUMBER OF SHARES AVAILABLE FOR OPTIONS.  The aggregate
 number of shares of common stock, no par value, of the Company (the
 "Shares") which may be issued under options granted pursuant to the
 Plan shall be 250,000.

     Section 3.  ADMINISTRATION OF THE PLAN.

     Section 3.1  GENERAL. The Plan shall be administered by a committee
 (the "Committee") consisting of at least two members designated by the
 Board of Directors of the Company from among those of its members who
 are not officers or employees of the Company or a parent or subsidiary
 of the Company and who otherwise satisfy the definition of a
 "Non-Employee Director" in Rule 16b-3(b)(3) promulgated under Section

                                     -1-

 16 of the Securities Exchange Act of 1934 (the "Exchange Act") and the
 definition of an "Outside Director" in the regulations under Section
 162(m) of the Code.  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.

     Section 3.2  AUTHORITY OF COMMITTEE.  The Committee shall have full
 and complete authority to grant options to such eligible employees on
 such terms, which need not be the same as to all Optionees, as will, in
 its discretion and subject only to the specific limitations elsewhere
 contained in the Plan, carry out the purpose of the Plan.  The
 Committee shall also have full and complete authority to interpret the
 Plan and adopt rules governing the administration of the Plan.  The
 Committee's decision on any matter with respect to the Plan shall be
 final.

    Section 3.3  INDEMNIFICATION OF COMMITTEE.  To the extent permitted
 by applicable law, the members of the Committee and each of them shall
 be indemnified and saved harmless by the Company from any liability or
 claim of liability which may arise from the administration of the Plan
 if the acts giving rise to such liability or claim of liability were
 taken in good faith and without negligence.

     Section 4.  ELIGIBLE EMPLOYEES.
<PAGE>
     Section 4.1  DEFINITION OF ELIGIBLE EMPLOYEES.  Subject to the
 limitations of Section 4.2, key employees of the Company and its
 subsidiary corporations shall be eligible to participate in the Plan.
 For purposes of the Plan, the term "key employee" shall include all
 employees of all participating employers employed in management,
 administrative or professional capacities.
                                     -2-
     Section 4.2  LIMITATIONS ON ELIGIBILITY.  No person who is serving
 as a member of the Committee shall be eligible to receive an option;
 provided, however, that options outstanding prior to an Optionee's
 becoming a member of the Committee shall remain in effect.

     Section 5.  GRANTING OF OPTIONS.  Subject to the limitations of
 Section 4.2, options to purchase Shares shall be granted to such key
 employees who are eligible to participate in the Plan as the Committee
 may, from time to time and at any time, select.  Membership in a class
 of eligible key employees shall not, without specific Committee action,
 entitle a key employee to receive an option to purchase Shares.
 Eligible key employees selected by the Committee shall be referred to
 herein as "Optionees."

     Section 6.  TERMS AND CONDITIONS OF THE OPTIONS.

     Section 6.1  WRITTEN INSTRUMENT.  Each option to purchase Shares
 granted under the Plan shall be evidenced by a written option agreement
 signed on behalf of the Company and the Optionee which sets forth the
 name of the Optionee, the date granted, the price at which the Shares
 subject to the option may be purchased (the "option price"), whether
 the option is an Incentive Stock Option or a Non-Qualified Stock
 Option, the number of Shares subject to the option and such other terms
 and conditions consistent with the Plan as determined by the Committee.
 The Committee may at the time of grant or at any time thereafter impose
 such additional terms and conditions on the exercise of such option as
 it deems necessary or desirable for compliance with Section 16 of the
 Exchange Act and the regulations promulgated thereunder.  Such option
 agreement shall incorporate by reference all terms, conditions and
 limitations set forth in the Plan.

                                     -3-

     Section 6.2  TERMS AND CONDITIONS OF THE OPTIONS.  In addition to
 any other limitations, terms and conditions specified in the Plan, each
 option granted hereunder shall, as to each Optionee, satisfy the
 following requirements:

          (a)  DATE OF GRANT.  Options must be granted on or before June
     18, 2001.

          (b)  EXPIRATION.  No Incentive Stock Option shall be
     exercisable after the expiration of ten years from the date such
     option is granted.  No Non-Qualified Stock Option shall be
     exercisable after the expiration of twenty years from the date such
     option is granted.

          (c)  PRICE.  The option price as to any Share subject to an
     Incentive Stock Option or Non-Qualified Stock Option will be not
     less than one hundred percent of the fair market value of the Share
     on the date the option is granted.
<PAGE
     For purposes of the Plan, the fair market value of a Share means:

     (i)  The mean between the high and the low prices at which the
          Shares were traded if the Shares were then listed for trading
          on a national or regional securities exchange or were then
          traded on a bona fide over-the-counter market; or

     (ii) If the Shares were not traded on an exchange or a bona fide
          over-the-counter market, a value determined by an appraiser
          selected by the Committee.

     In the event that the date on which the fair market value of a
     Share is to be determined is a date on which there is no trading of
     the Shares on a national or regional securities exchange or on the
     over-the-counter market, such fair market value shall be determined
     by referring to the next preceding business day on which trading
     occurs.
                                     -4-
          (d)  TRANSFERABILITY.

     (i)  No Incentive Stock Option shall be transferable by the
          Optionee otherwise 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.

     (ii) The Committee may, in its discretion, authorize all or a
          portion of any options to be granted to an Optionee or which
          were granted to any Optionee on or before December 16, 1996 to
          permit transfer by the Optionee to (A) the spouse, children or
          grandchildren of the Optionee ("Immediate Family"), (B) a
          trust for the exclusive benefit of the Optionee or the
          Optionee's Immediate Family, (C) a partnership in which the
          Optionee or the Optionee's Immediate Family are the only
          partners, or (D) to a former spouse of the Optionee pursuant
          to a domestic relations order within the meaning of Rule
          16a-12 promulgated under Section 16 of the Exchange Act;
          provided, however, that (X) there may be not consideration for
          any such transfer, (Y) the written option agreement required
          by Section 6.1, or any amendment thereof approved by the
          Committee, must expressly provide for transferability of the
          option evidenced in such agreement in a manner consistent with
          this Section 6.2(d), and (Z) once transferred pursuant to the
          preceding provisions of this Section 6.2(d)(ii), no subsequent
          transfer of any options shall be permitted except a transfer
          by will or the laws of descent and distribution.  In
          authorizing all or any portion of an option to be transferred,
          the Committee may impose any conditions on exercise, prescribe
          a holding period for the Shares acquired upon such exercise
          and/or impose any other conditions or limitations it deems
          desirable or necessary in order to carry out the purposes and
                                     -5-
          requirements of the Plan.  Following transfer, the terms and
          conditions of the plan and the written option agreement
          relating to such option shall continue to be applicable in all
          respects to the Optionee making such transfer and each
          transferred option shall continue to be subject to the same
          terms and conditions as were applicable immediately prior to
          transfer as if such option had not been transferred,
<PAGE>
          including, but not limited to, the terms and conditions with
          respect to the lapse and termination of such option.  For
          purposes of Section 7, the transferee of an option shall be
          deemed an "Optionee".  Neither the Company, the Committee or
          any Optionee shall have any obligation to inform any
          transferee of the termination or lapse of any option for any
          reason.  Notwithstanding any other provision of the plan, (YY)
          following the termination of employment of an Optionee, a
          transferred Non-Qualified Option shall be exercisable by the
          transferee only to the extent, and for the periods specified
          in Section 6(e) as if such option had not been transferred and
          (ZZ) no Non-Qualified Stock Option granted prior to November
          1, 1996 may be transferred until such option has been held by
          the Optionee for a period of not less than six months after
          the date on which such option was granted.

          (e)  EMPLOYMENT.
     (i)   Except as otherwise provided in Section 6.2(e)(ii), no option
           shall be exercisable unless the Optionee shall have been
           employed by the Company (or any present or future parent or
           subsidiary of the Company) during the period beginning on the
           date the option is granted and ending on a date ninety days
                                     -6-
           before the date of exercise; provided, however, that in the
           event an Optionee dies while in the employ of the Company (or
           any present or future parent or subsidiary of the Company) or
           within ninety days after such employment had terminated, the
           employment period requirement described above (the "90-day
           limit") shall be deemed to have been satisfied, and, provided
           further, that the Committee may permit the exercise of a
           Non-Qualified Stock Option without regard to "90-day limit"
           if (A) the Optionee (or the Optionee's personal
           representative or estate in the event of the Optionee's
           death) is, in the sole discretion of the Committee, directly
           or indirectly prevented from exercising such option by reason
           of the application of federal securities laws within the
           90-day limit or the Company or its shareholders would be
           adversely affected by reason of the application of federal
           securities laws to an exercise of such option within such
           90-day limit, (B) the Optionee was not, at the time of his
           termination of employment, a person with respect to whom
           payment of compensation by the Company is then subject to (or
           would be, but for an exemption from) the provisions of
           Section 162(m) of the Code, and (C) such action by the
           Committee would not adversely affect the tax or accounting
           practices of the Company or otherwise adversely affect the
           business or operations of the Company.

     (ii) In the event an Optionee has attained his Retirement Date (as
          defined herein), (A) the provisions of Section 6(e)(i) shall
          not be applicable to such Optionee's Non-Qualified Stock
          Options and (B) such Optionee's Non-Qualified Stock Options
          shall not be exercisable after the second anniversary of such
                                     -7-
          Optionee's Retirement Date.  For purposes of this Plan, the
          term "Retirement Date" shall mean the date on which the
          Optionee's employment with the Company (and any parent or
          subsidiary of the Company) terminates (including termination
<PAGE>
          because of death) if the Optionee had then attained age 55 and
          completed ten calendar years of service with the Company (or
          any parent or subsidiary of the Company).

          (f)  MINIMUM HOLDING PERIOD.  No option granted prior to
     November 1, 1996 may be exercised before the date which is six
     months after the date on which such option was granted.  Each
     option shall contain such additional or other restriction or
     restrictions with respect to the stated percentage of Shares
     covered by such option as to which such option may be exercised as
     the Committee may deem desirable or necessary in order to carry out
     the purposes and requirements of the Plan.

          (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 granted) of the
     Shares for which Incentive Stock Options are exercisable for the
     first time by an individual during any calendar year (under this
     Plan or any other plan of the Company or any of its subsidiaries)
     exceeds $100,000 (or such other individual limit as may be in
     effect under the Code on the date of grant), such options shall not
     be Incentive Stock Options.  No Incentive Stock Option shall be
     granted to an employee who, at the time such option is granted,
     owns stock possessing more than ten percent of the total combined
     voting power of all classes of stock of the Company or any parent
     or subsidiary of the Company within the meaning of Section
     422(b)(6) of the Code unless: (i) at the time the option is
     granted, the option price is at least one hundred ten percent of
                                     -8-
     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 granted.

          (h)  LIMITATION ON OPTION GRANTS.  No Optionee may be granted
     options under Section 5 of the Plan in any fiscal year with respect
     to more than 50,000 Shares.

     Section 7.  EXERCISE AND PAYMENT OF OPTION PRICE.

     Section 7.1  EXERCISE OF OPTIONS.  Options shall be exercised as to
 all or a portion of the Shares 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 required tax withholding).  The date of exercise shall be the
 date such written notice and payment have been 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.  Notwithstanding the fact
 that an option has been transferred pursuant to Section 6.2(d)(ii), the
 grantee of such option shall remain liable for any required tax
 withholding.

     Section 7.2  PAYMENT FOR SHARES.  Payment of the option price (plus
 required tax withholding) may be made by (a) tendering cash (in the
 form of a check or otherwise) in such amount, or (b) tendering Shares
 with a fair market value on the date of exercise equal to such amount,

     Section 8.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION.  If any
 option is exercised in whole or in part subsequent to any stock

 which (a) shares of any class or classes of the Company shall be issued
 in respect of the Shares or (b) the Shares shall be changed into the
 same or a different number of shares of the same or another class or
 classes of the Company or another corporation, the Optionee so
 exercising the option shall receive, for the aggregate option price

 of shares equal to the number and class or classes of shares such
 Optionee would have had on the date of actual exercise if the Optionee
 had purchased on the date the option was granted the Shares as to which

 consideration such stock dividend, stock split, recapitalization,
 reorganization, merger or other change in the corporate structure of

 terminate or lapse upon the first to occur of (a) the expiration date

 following the last day such option could be exercised by the Optionee

 Optionee's death while in the employ of the Company or a parent or
 subsidiary of the Company or, if the Optionee is no longer so employed,
 in the event of the Optionee's death on or before the last day such
 option could be exercised by the Optionee under Section 6.2(e), an
 option may be exercised, to the extent exercisable by the Optionee
 immediately prior to his death, in whole or in part by the Optionee's
 estate or his designee by will, or, if applicable, the transferee of
                                     -10-

     Section 10.1  AMENDMENT OF PLAN.  The Board of Directors of the
 Company may amend the Plan from time to time and at any time; provided,
 however, that no amendment shall adversely affect any option which has
 been granted prior to the amendment and no amendment with respect to
 the maximum number of Shares which may be issued pursuant to options or
 the class of eligible employees, or which constitutes a change in the
 material terms of the Plan (within the meaning of section 162(m) of the
 Code) shall be effective unless approved by a majority of the shares
 entitled to vote at a meeting of shareholders.
<PAGE>

     Section 12.  INVESTMENT INTENT.  Shares acquired pursuant to the
 exercise of an option, if not registered by the Company under the
 Securities Act of 1933 (the "Act"), will be "restricted" stock which
 will not be freely transferable by the holder after exercise of the
 option.  Each participating employee and assignee in interest of the
 employee accordingly represents, as a condition of participation in the
 Plan, that Shares which are unregistered under the Act are being
 acquired for the Optionee's (or his assignee's) own account for
 investment only and not with a view to offer for sale or for sale in
 connection with the distribution or transfer thereof.

     Section 13.  AVAILABILITY OF INFORMATION.  The Company shall

 authorized representative of the Optionee, copies of all reports filed
 by the Company with the Securities and Exchange Commission or the
 commissioner of securities of any state, including, but not limited to,
 the Company's annual reports on Form 10-K, its quarterly reports on
 Form 10-Q, and its proxy statements.

     Section 14.  CONDITIONS OF EMPLOYMENT.  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 parent or subsidiary of the Company and the Company
 and its participating subsidiaries hereby expressly reserve the right
 to terminate the employment of any employee, with or without cause, as
                                    -12-
 if the Plan and any options granted pursuant to it were not in effect.

     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
<PAGE>
          either (i) the then outstanding Shares (the "Outstanding
          Company Common Stock") or (ii) the combined voting power of
          the then outstanding voting securities of the Company entitled
          to vote generally in the election of directors (the
          "Outstanding Company Voting Securities"); excluding, however,
          the following: (A) any acquisition directly from the Company
          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 Company, (B) any
          acquisition by the Company, (C) any acquisition by any
          employee benefit plan (or related trust) sponsored or
          maintained by the Company or any entity controlled by the
          Company, (D) any acquisition pursuant to a transaction which
          complies with clauses (i), (ii), and (iii) of paragraph (c) of

          Stock or Outstanding Company Voting Securities beneficially
          owned by a Person to 20% or more of the shares of either of
                                     -13-
          such classes of stock if such increase was solely the result
          of the acquisition of Outstanding Company Common Stock or
          Outstanding Company Voting Securities by the Company;
          provided, however, that this clause (F) shall not apply to any
          acquisition of Outstanding Company Common Stock or Outstanding
          Company 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
          Company Common Stock or Outstanding Company Voting Securities
          by reason of share purchases by the Company; or 

          (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 nomination for election by the
               Company's shareholders, was approved by a vote of at
               least a majority of those individuals who are members of
               the Board and who were also members of the Incumbent
               Board (or deemed to be such pursuant to this proviso)
               shall be deemed to be and shall be considered as though
               such individual were a member of the Incumbent Board, but
               provided, further, that any such individual whose initial
               assumption of office occurs as a result of either an
               actual or threatened election contest (as such terms are
               used in Rule 14a-11 of Regulation 14A

                                    -14-

          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

     (c)  Consummation of a reorganization, merger or consolidation, or
          sale or other disposition of all or substantially all of the
          assets of the Company or the acquisition of the assets or
          securities of any other entity (a "Corporate Transaction");
          excluding, however, such a Corporate Transaction pursuant to
          which (i) all or substantially all of the individuals and
          entities who are the beneficial owners, respectively, of the
          Outstanding Company Common Stock and Outstanding Company
          Voting Securities immediately prior to such Corporate
          Transaction will beneficially own, directly or indirectly,

          (including, without limitation, a corporation which as a
          result of such transaction owns the Company or all or
          substantially all of the Company's assets either directly or
          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 Company Common Stock and Outstanding Company
          Voting Securities, as the case may be, (ii) no Person (other
          than the Company, any employee benefit plan (or related trust)
          of the Company, any Woodson Entity, any Smith Entity, or such
          Resulting Corporation) will beneficially own, directly or
          indirectly, 20%

                                    -15-

          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 Company 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

     For purposes of this Section 15.1, the term "Woodson Entities"
     shall mean Aytchmonde P. Woodson, Leigh Yawkey Woodson and Alice
     Richardson Yawkey, members of their respective families and their
     respective descendants (the "Woodson Family"), heirs or legatees of
     any of the

                                   -16-

     For purposes of this Section 15.1, the term "Smith Entities" shall

     Section 15.2  EFFECTS OF CHANGE IN CONTROL.
<PAGE>
     (a)  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") shall, to
          the extent not then exercisable or vested, immediately become
          exercisable in full, and

     (ii) each Optionee may elect, with respect to each option held by
          such Optionee on the Change in Control Date (the Optionee's
          "Election Right"), 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 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 15.2, 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 15.1(c), the
          highest price per Share paid in such tender or exchange offer
          or Corporate Transaction;

                                     -18-

          provided, however, that in the case of Incentive Stock
          Options, the Change in Control Price shall be in all cases
          the Fair Market Value of the Shares on the date such Incentive
          Stock Option is exercised.  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.

     (b)  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)  All payments due an Optionee pursuant to the provisions of
          this Section 15.2 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 15.2(b).

     (d)  Notwithstanding any other provision of this Section 15.2, if
          the grant or the exercise of an Optionee's Election Right or
          payment of cash provided for in  Section 15.2(b) would make a
          Change in Control transaction ineligible for
          pooling-of-interests accounting treatment under APB No. 16,
          that, but for the nature of such grant or exercise of Election
          Rights or payment of cash, would otherwise be eligible for

                                     -19-
<PAGE>
          such pooling-of-interests accounting treatment, the
          Committee shall have the right and authority to substitute for
          the cash payments to be made to the Optionee pursuant to
          Section 15.2(a), Common Stock with a fair market value,
          determined as of the date of delivery of such Shares, equal to
          the cash that would otherwise be payable to such Optionee in
          connection with the exercise of an Optionee's Election Right
          hereunder or, to the extent necessary to preserve such
          pooling-of-interests accounting treatment, to otherwise
          modify, eliminate, or terminate such Election Right.

                      WAUSAU-MOSINEE PAPER CORPORATION
                          DIVIDEND EQUIVALENT PLAN

                          As amended March 4, 1999

                      WAUSAU MOSINEE PAPER CORPORATION
                          DIVIDEND EQUIVALENT PLAN

 1.  PURPOSE.

     The purpose of the Wausau-Mosinee Paper Corporation Dividend
 Equivalent Plan (the "Plan") is to attract and retain outstanding
 individuals as officers and key employees of Wausau-Mosinee Paper
 Corporation (the "Company") and its subsidiaries, and to furnish
 incentives to such individuals through rewards based upon the
 performance of the Company and its common stock.  To this end, the
 Committee hereinafter designated may grant dividend equivalents to
 officers and other key employees of the Company and its subsidiaries,
 on the terms and subject to the conditions set forth in this Plan.

 2.  PARTICIPANTS.

     Participants in the Plan shall consist of such officers and other
 key employees of the Company and its subsidiaries as the Committee in
 its sole discretion may select from time to time to receive dividend
 equivalents.

 3.  ADMINISTRATION OF THE PLAN.

     The Plan shall be administered by a committee (the "Committee")
 consisting of at least two members designated by the Board of Directors
 of the Company from among those of its members who are not officers or
 employees of the Company or a parent or subsidiary of the Company and
 who otherwise satisfy the definition of a "Non-Employee Director" in
 Rule 16b-3(b)(3) promulgated under Section 16 of the Securities
 Exchange Act of 1934 (the "Exchange Act").  In the absence of specific

                                     -1-
<PAGE>
 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.  Subject to the provisions of the Plan, the Committee shall
 have authority (a) to determine which employees of the Company and its
 subsidiaries shall be eligible for participation in the Plan; (b) to
 select employees to receive grants under the Plan; (c) to determine the
 number of dividend equivalents subject to the grant, the time and
 conditions of vesting, and all other terms and conditions of any grant;
 (d) to determine the fair market value of the common stock of the
 Company for purposes of the Plan; and (e) to prescribe the form of
 agreement, certificate or other instrument evidencing the grant.  The
 Committee shall also have authority to interpret the Plan and to
 establish, amend and rescind rules and regulations for the
 administration of the Plan, and all such interpretations, rules and
 regulations shall be conclusive and binding on all persons; provided,
 however, that the Committee shall not exercise such authority in a
 manner adversely and significantly affecting dividend equivalents
 previously granted unless the action taken is required to comply with
 any applicable law or regulation.

 4.  EFFECTIVE DATE AND TERM OF PLAN.

     The Plan shall become effective on June 19, 1991, the date of its
 approval by the Board of Directors of the Company.  The Plan shall
 terminate ten years after it becomes effective, unless terminated
 sooner by action of the Board of Directors.  No further grants may be
 made under the Plan after its termination, but the termination of the
 Plan shall not affect the rights of any participant under, or the
 authority of the Committee with respect to, any grants made prior to
 termination.

                                     -2-

 5.  SHARES SUBJECT TO THE PLAN.

     Subject to adjustment as provided in Section 7 hereof, the
 aggregate number of shares of common stock of the Company with respect
 to which dividend equivalents may be granted under the Plan shall not
 exceed 250,000.  Whenever dividend equivalents granted under the Plan
 are forfeited, the shares subject to such dividend equivalents shall
 thereupon be released from such dividend equivalents and shall
 thereafter be available for additional grants of dividend equivalents
 under the Plan.

 6.  DIVIDEND EQUIVALENTS.

     (a)  Grants.  Dividend equivalents entitling the grantee to receive
 cash equal to the value of the hypothetical reinvested cash dividends
 (defined below) which would have been paid with respect to a stated
 number of shares of common stock of the Company between the date of
 grant and the date of termination of the grantee's employment with the
 Company and its subsidiaries may be granted from time to time to such
 officers and other key employees of the Company and its subsidiaries as
 may be selected by the Committee.
<PAGE>
     (b)  Vesting of Grant.  Dividend equivalents shall vest in whole or
 in such installments and at such times as may be determined by the
 Committee.

     (c)  Payment.  The value of dividend equivalents granted prior to
 December 16, 1996 shall be paid to the grantee (or his beneficiary in
 the event of his death) in the amount determined in accordance with
 this Section 6(c) upon the grantee's termination of employment with
 the Company and its subsidiaries; provided, however, if the grantee's
 termination occurred on his Retirement Date, the value of such dividend
 equivalents shall be paid to the grantee (or his beneficiary in the
 event of his death) on the first to occur of (i) his Retirement Date

                                     -3-

 if the grantee had exercised a stock option granted in tandem with the
 grant of such dividend equivalents on or before such Retirement Date,
 (ii) if the grantee had not exercised a stock option granted in tandem
 with the grant of such dividend equivalents on or before such
 Retirement Date, the first date after his Retirement Date on which the
 grantee exercises such stock option granted in tandem with the grant of
 such dividend equivalents, and (iii) the second anniversary of such
 grantee's Retirement Date; provided, however, in each case, that only
 the value of such proportion of the dividend equivalent as it
 corresponds to the proportion of shares subject to such option as are
 exercised shall be paid.   The value of dividend equivalents granted on
 or after December 16, 1996 shall be paid to the grantee (or his
 beneficiary in the event of his death) in the amount determined in
 accordance with this Section 6(c) upon the first to occur of (i) the
 grantee's termination of employment with the Company and its
 subsidiaries and (ii) the date on which the grantee exercises a stock
 option granted in tandem with the grant of such dividend equivalents;
 provided, however, if the grantee's termination occurred on his
 Retirement Date, the value of such dividend equivalents shall be paid
 to the grantee (or his beneficiary in the event of his death) on the
 first to occur of (i) the first date after his Retirement Date on which
 the grantee exercises a stock option granted in tandem with the grant
 of such dividend equivalents and (ii) the second anniversary of such
 grantee's Retirement Date; provided, however, in each case, that only
 the value of such proportion of the dividend equivalent as corresponds
 to the proportion of shares subject to such option as are exercised
 shall be paid.  For purposes of this Plan, the term "Retirement Date"
 shall mean the date on which the grantee's employment with the Company
 (and any parent or subsidiary of the Company) terminates (including
 termination because of death) if the grantee had

                                     -4-

 then attained age 55 and completed ten calendar years of service with
 the Company (or any parent or subsidiary of the Company).  An option
 shall be deemed to have been granted in tandem with a grant of dividend
 equivalents if such option grant was made at or about the same date,
 relates to the same number of shares of common stock and is subject to
 the same conditions on vesting or exercise the grant of such dividend
 equivalents.  The value of the dividend equivalents to be paid pursuant
 to this Section 6(c) shall be an amount in cash equal to the value of
<PAGE>
 the hypothetical reinvested cash dividends associated with the
 aggregate number of shares of common stock of the Company with respect
 to which such dividend equivalents have been granted to the grantee. 
 The value of the hypothetical reinvested cash dividends associated with
 a share of common stock of the Company in respect of which a dividend
 equivalent has been granted shall be equal to the fair market value on
 the date of payment of the value of such dividend equivalents is
 provided for herein of the number of shares (or fraction thereof) of
 the Company's common stock which the grantee would have owned if it is
 assumed (i) that cash dividends which would have been paid with respect
 to the share if the share had been outstanding from the date of grant
 of the dividend equivalent had been paid in cash to the grantee and
 then immediately reinvested by the grantee in the Company's common
 stock at the fair market value thereof on the applicable dividend
 payment date, and (ii) that, once assumed issued, hypothetical shares
 resulting from assumed dividend reinvestment themselves paid cash
 dividends (at the same time and in the same amount as shares of the
 Company's outstanding common stock) which were reinvested in a similar
 manner.

                                     -5-

     (d)  Additional Terms and Conditions.  The agreement or instrument
 evidencing the grant of dividend equivalents may contain such other
 terms, provisions and conditions not inconsistent with the Plan as may
 be determined by the Committee in its sole discretion.  The Committee
 may at the time of grant or at any time thereafter impose such
 additional terms and conditions on dividend equivalents as it deems
 necessary or desirable for compliance with Section 16(a) or 16(b) of
 the Securities Exchange Act of 1934 and the rules and regulations
 thereunder.

 7.  ADJUSTMENTS FOR CHANGES IN CAPITALIZATION, ETC.

     Dividend equivalents shall be subject to adjustment by the
 Committee in its sole discretion as to the number of shares subject to
 such grants in the event of changes in the outstanding common stock of
 the Company by reason of stock dividends, stock splits,
 recapitalizations, reorganizations, mergers, consolidations,
 combinations, exchanges or other relevant changes in corporate
 structure or capitalization occurring after the date of the grant of
 any dividend equivalent, provided that if the Company shall change its
 common stock into a greater or lesser number of shares through a stock
 dividend, stock split-up, or combination of shares, outstanding
 dividend equivalents shall be adjusted proportionately, consistent with
 existing law and regulation, to prevent inequitable results.

 8.  EFFECT OF LIQUIDATION, MERGER, CONSOLIDATION OR OTHER EVENTS.

     Nothing contained in the Plan or in any dividend equivalent granted
 under the Plan shall in any way prohibit the Company from merging with
 or consolidating into another company, or from selling or transferring
 all or substantially all of its assets, or from distributing all or
 substantially all of its assets to its stockholders in liquidation, or

                                     -6-
<PAGE>
 from dissolving and terminating its corporate existence; and in any
 such event, payment shall be made with respect to all then outstanding
 dividend equivalents (whether or not then vested) as if all of the
 grantees of such dividend equivalents had terminated employment with
 the Company and its subsidiaries at the time of such merger,
 consolidation, sale or transfer of assets, liquidation, or dissolution,
 except to the extent that any agreement or undertaking of any party to
 such merger, consolidation, or sale or transfer of assets, or any plan
 pursuant to which such liquidation or dissolution is effected, shall
 make specific provision to continue such dividend equivalents and the
 rights of the grantees under such dividend equivalents.

 9.  AMENDMENT AND TERMINATION OF PLAN.

     The Plan may be amended or terminated by the Board of Directors of
 the Company in any respect; provided, however, that the Board shall not
 exercise such authority in a manner adversely and significantly
 affecting dividend equivalents previously granted unless the action
 taken is required to comply with any applicable law or regulation.

 10. MISCELLANEOUS.

     (a)  No Right to a Grant.  Neither the adoption of the Plan nor any
 action of the Board of Directors or of the Committee shall be deemed to
 give any employee any right to be selected as a participant or to be
 granted a dividend equivalent.

     (b)  Rights as Stockholder.  No person shall have any rights as a
 stockholder of the Company with respect to any shares covered by
 dividend equivalents.

     (c)  Employment.  Nothing contained in this Plan shall be deemed to
 confer upon any employee any right of continued employment with the
 Company or any of its subsidiaries or to limit or diminish in any way

                                     -7-

 the right of the Company or any such subsidiary to terminate his or her
 employment at any time with or without cause.

     (d)  Taxes.  The Company shall be entitled to deduct from any
 payment under the Plan the amount of any tax required by law to be
 withheld with respect to such payment or may require any participant to
 pay such amount to the Company prior to and as a condition of making
 such payment.

     (e)  Nontransferability.  No dividend equivalent shall be
 transferable.

 11.  CHANGE IN CONTROL.

     (a)  Definition of "Change in Control."  For purposes of the Plan,
 a "Change in Control" means the happening of any of the following
 events:

          (i)  The acquisition by any individual, entity or group
<PAGE>
     (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 (A) the then outstanding Shares (the "Outstanding Company
     Common Stock") or (B) the combined voting power of the then
     outstanding voting securities of the Company entitled to vote
     generally in the election of directors (the "Outstanding Company
     Voting Securities"); excluding, however, the following: (1) any
     acquisition directly from the Company 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
     Company, (2) any acquisition by the Company, (3) any acquisition by
     any employee benefit plan (or related trust) sponsored or
     maintained by the Company or any entity controlled by the Company,
     (4) any acquisition pursuant to a transaction which complies with

                                     -8-

     clauses (A), (B), and (C) of paragraph (iii) of this Section 11(a),
     (5) except as provided in paragraphs (iv) and (v), any acquisition
     by any of the Woodson Entities or any of the Smith Entities, or (6)
     any increase in the proportionate number of shares of Outstanding
     Company Common Stock or Outstanding Company Voting Securities
     beneficially owned by a Person to 20% or more of the shares of
     either of such classes of stock if such increase was solely the
     result of the acquisition of Outstanding Company Common Stock or
     Outstanding Company Voting Securities by the Company; provided,
     however, that this clause (6) shall not apply to any acquisition of
     Outstanding Company Common Stock or Outstanding Company Voting
     Securities not described in clauses (1), (2), (3), (4), or (5) of
     this paragraph (i) by the Person acquiring such shares which occurs
     after such Person had become the beneficial owner of 20% or more of
     either the Outstanding Company Common Stock or Outstanding Company
     Voting Securities by reason of share purchases by the Company; or

          (ii)  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 nomination for election by the
     Company's shareholders, was approved by a vote of at least a
     majority of those individuals who are members of the Board and who
     were also members of the Incumbent Board (or deemed to be such
     pursuant to this proviso) shall be deemed

                                    -9-

     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
<PAGE>
          (iii)  Consummation of a reorganization, merger or
     consolidation, or sale or other disposition of all or substantially
     all of the assets of the Company or the acquisition of the assets
     or securities of any other entity (a "Corporate Transaction");
     excluding, however, such a Corporate Transaction pursuant to which
     (A) all or substantially all of the individuals and entities who
     are the beneficial owners, respectively, of the Outstanding Company
     Common Stock and Outstanding Company Voting Securities immediately
     prior to such Corporate Transaction will beneficially own, directly
     or indirectly, more than 60% of, respectively, the outstanding
     shares of common stock and the combined voting power of the then
     outstanding voting securities entitled to vote generally in the
     election of directors, as the case may be, of the corporation
     resulting from such Corporate Transaction (including, without
     limitation, a corporation which as a result of such transaction
     owns the Company or all or substantially all of the Company's
     assets either directly or through one or more subsidiaries)
     (the "Resulting Corporation") in substantially the same proportions
     as their ownership, immediately prior to such Corporate 

                                     -10-

     Transaction, of the Outstanding Company Common Stock and
     Outstanding Company Voting Securities, as the case may be, (B) no
     Person (other than the Company, any employee benefit plan (or
     related trust) of the Company, 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 Company prior to the Corporate
     Transaction, and (C) individuals who were members of the
     Incumbent Board will constitute at least a majority of the members
     of the board of directors of the Resulting Corporation; or

           (iv)  The Woodson Entities acquire beneficial ownership of
     more than 35% of the Outstanding Company Common Stock or
     Outstanding Company 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

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

                                     -11-

          (vi)  The approval by the shareholders of the Company of a
     complete liquidation or dissolution of the Company.
<PAGE>
     For purposes of this Section 11(a), the term "Woodson Entities"
 shall mean Aytchmonde P. Woodson, Leigh Yawkey Woodson and Alice
 Richardson Yawkey, members of their respective families and their
 respective descendants (the "Woodson Family"), heirs or legatees of any
 of the Woodson Family members, transferees by will, laws of descent or
 distribution or by operation of law of any of the foregoing (including
 of any such transferees) (including any executor or administrator of
 any estate of any of the 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 Company
 (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 11(a), the term "Smith Entities" shall
 mean David B. Smith and Katherine S. Smith, members of their respective
 families and their respective descendants (the "Smith Family"), heirs
 or legatees of any of the Smith Family members, transferees by will,
 laws of descent or distribution or by operation of law of any of the
 foregoing (including of any such transferees) (including any executor
 or administrator of any estate of any of the foregoing), any trust
 established by either of David B. Smith or Katherine S. Smith, whether

                                    -12-

 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

 12b-2 of the General Rules and Regulations under the Exchange Act as in
 effect on the date of this Plan.

     (b)  Effects of Change in Control.  In the event of a Change in
 Control,

          (i)  all dividend equivalents outstanding on the date on which
     such Change in Control has occurred (the "Change in Control Date")
     shall, to the extent not then vested, immediately become vested in
     full, and

          (ii)  each grantee may elect, with respect to each dividend
     equivalent held by such grantee on the Change in Control Date (the
<PAGE>
     grantee's "Election Right"), to surrender such dividend equivalent
     for an immediate lump sum cash payment in an amount equal to the
     value of the hypothetical reinvested cash dividends associated with
     the aggregate number of shares of common stock of the Company with
     respect to which such dividend equivalents have been granted to the
     grantee; provided, however, that the value of such hypothetical
     reinvested cash dividends shall be determined by the greater of (A)
     the Change in Control Price or (B) the highest fair market value

                                    -13-

     of a share of common stock on any day in the 60-day period ending
     on the Change in Control Date.  For purposes of this Section 11(b),
     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 11(a)(iii)), the highest price
     per share of common stock paid in such tender or exchange offer
     or Corporate Transaction.  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.

                                    -14-

               SUPPLEMENTAL RETIREMENT BENEFIT PLAN


     This Supplemental Retirement Benefit Plan (the "Plan"), adopted
 effective as of this 16th day of January, 1992, and amended November
 13, 1995 and December 21, 1998, by Wausau-Mosinee Paper Corporation, a
 Wisconsin corporation ("Wausau"), for the purposes of providing
 deferred compensation in the form of supplemental retirement benefits
 for San W. Orr, Jr. ("Mr. Orr") in recognition of his service to Wausau
 as its Chairman of the Board of Directors and Chief Executive Officer
 is hereby further amended effective as of this 4th day of March, 1999.

     1.      NORMAL SUPPLEMENTAL RETIREMENT BENEFIT.  Beginning on the
 first day of the first month following the last to occur of (a) Mr.
 Orr's termination of employment with Wausau or (b) Mr. Orr's 60th
 birthday, and continuing on the first day of each succeeding month,
 Wausau shall pay to Mr. Orr, if he is then living, a monthly
 supplemental retirement benefit (Mr. Orr's "Normal Supplemental
 Retirement Benefit") in an amount equal to 50% of one-twelfth of
 Mr. Orr's highest final average compensation.  For purposes of this
 Plan, "highest final average compensation" shall mean the annual
 average of the sum of (a) all compensation paid to Mr. Orr and reported
 on Form W-2 and (b) all amounts which would have been paid and reported
 on Form W-2 but were deferred at Mr. Orr's election for the five
 consecutive calendar year period which yields the highest aggregate
 compensation so paid and deferred.  Mr. Orr's Normal Supplemental
 Retirement Benefit shall not be reduced or offset by the amount of any
<PAGE>
 other payment then due him from Wausau or any other plan or program now
 or hereafter maintained by Wausau.

                                     -1-

     2.   SURVIVING SPOUSE BENEFIT.  From and after the first day of the
 first month following the later of (a) the month in which Mr. Orr's
 death occurs or (b) the month in which Mr. Orr would have attained his
 60th birthday if Mr. Orr's death occurs before he has attained age 60,
 and continuing on the first day of each succeeding month, Wausau shall
 pay to Mr. Orr's spouse, if then living (Mr. Orr's "Surviving Spouse"),
 a monthly benefit (the "Supplemental Surviving Spouse Benefit") in an
 amount equal to 50% of the Normal Supplemental Retirement Benefit to
 which Mr. Orr would have then been entitled had he then been living.

     3.   CHANGE IN CONTROL OF WAUSAU.
          (a)  In the event a Change in Control of Wausau occurs prior
     to Mr. Orr's death, Wausau shall pay to Mr. Orr a lump sum
     amount equal to the present value of Mr. Orr's Normal
     Supplemental Retirement Benefit, as determined hereunder, as
     of the first day of the first month following such Change in
     Control of Wausau on which Mr. Orr is neither an employee nor
     a director of Wausau, whether or not such Change in Control
     occurred prior to the date on which Mr. Orr shall have ceased
     to be an employee or a director of Wausau.  Upon payment

                                     -2-

     of the lump sum amount provided for in this subparagraph (a),
     Wausau shall have no further obligation to pay any benefits under
     this Plan.

          (b)  In the event a Change in Control occurs after Mr. Orr's
     death and whether or not the Supplemental Surviving Spouse Benefit
     shall have then become payable, Wausau shall pay to Mr. Orr's
     Surviving Spouse, if then living, the present value of the unpaid
     Supplemental Surviving Spouse Benefit.  Upon payment of the lump
     sum amount provided for in this subparagraph (b), Wausau shall have
     no further obligation to pay any benefits under this Plan.

          (c)  For purposes of this plan, a "Change in Control of
     Wausau" shall be mean the happening of any of the following events:

          (1)  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 (A) the then outstanding shares of
          common stock of Wausau (the "Outstanding Corporation Common
          Stock") or (B) the combined voting power of the then
          outstanding voting securities of Wausau entitled to vote
          generally in the election of directors (the "Outstanding
          Corporation Voting Securities"); excluding, however,
          the following: (i) any acquisition directly from Wausau other
          than an acquisition by virtue of the exercise of a conversion
<PAGE>
          privilege unless the security being so converted was itself
          acquired directly from Wausau, (ii) any acquisition by Wausau,
          (iii) any acquisition by any employee benefit plan (or related
          trust) sponsored or maintained by Wausau or any entity
          controlled by Wausau, (iv) any acquisition pursuant to a
          transaction which complies with clauses (A), (B), and (C) of
          paragraph (3) of this Section 3(c), (v) except as provided in
          paragraphs (4) and (5), any acquisition by any of the Woodson
          Entities or any of the Smith Entities, or (vi) any increase in
          the proportionate number of shares of Outstanding 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
          Wausau; provided, however, that this clause (vi) shall not
          apply to any acquisition of Outstanding Corporation Common
          Stock or Outstanding Corporation Voting Securities not
          described in clauses (1), (ii), (iii), (iv), or (v) of this
          paragraph (1) by the Person acquiring such shares which occurs
          after such Person had become the beneficial owner of 20% or
          more of either the Outstanding Corporation Common Stock or
          Outstanding Corporation Voting Securities by reason of share
          purchases by Wausau; or

          (2)  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
          nomination for election by Wausau's shareholders, was approved
          by a vote of at least a

                                    -3-

          majority of those individuals who are members of the Board and
          who were also members of the Incumbent Board (or deemed to be
          such pursuant to this proviso) shall be deemed to be and shall
          be considered as though such individual were a member of the
          Incumbent Board, but provided, further, that any such
          individual whose initial assumption of office occurs as a
          result of either an actual or threatened election 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

          (3)  Consummation of a reorganization, merger or

                      WAUSAU-MOSINEE PAPER CORPORATION
                   DIRECTORS' DEFERRED COMPENSATION PLAN

                          As amended March 4, 1999

                 WAUSAU-MOSINEE PAPER CORPORATION

               DIRECTORS' DEFERRED COMPENSATION PLAN


     1.   ESTABLISHMENT OF PLAN.  Wausau-Mosinee Paper Corporation (the
 "Company") hereby amends and restates the Company's Directors' Deferred
 Compensation Plan previously in effect and renames such plan, as herein
 amended and restated, the Wausau-Mosinee Paper Corporation Directors'
 Deferred Compensation Plan, all effective as of December 17, 1997 (the
 "Plan").

     2.   PURPOSE. The purpose of the Plan is to provide an alternative
 method of compensating members (the "Directors") of the Board of
 Directors of the Company (the "Board"), whether or not they otherwise
 receive compensation as employees of the Company, in order to aid the
 Company in attracting and retaining as Directors persons whose
 abilities, experience, and judgment can contribute to the continued
 progress of the Company and to provide a mechanism by which the
 interests of the Directors and the shareholders can be more closely 
 aligned.

     3.   DEFINITIONS.  As used in this Plan, the following terms shall
 have the meaning set forth in this paragraph 3:

     (a) "BENEFICIARY" shall mean such person or persons, or
 organization or organizations, as the Participant from time to time may
 designate by a written designation filed with the Company during the
 Participant's life. Any amounts payable hereunder to a Participant's
 Beneficiary shall be paid in such proportions and subject to such
 trusts, powers, and conditions as the Participant may provide in such

                                     -1-

 designation.  Each such designation,unless otherwise expressly provided
 therein, may be revoked by the Participant by a written revocation
 filed with the Company during the Participant's life.  If more than one
 such designation shall be filed by a Participant with the Company, the
 last designation so filed shall control over any revocable designation
 filed prior to such filing.  To the extent that any amounts payable
 under this Plan to a Participant's Beneficiary are not effectively
 disposed of pursuant to the above provisions of this paragraph 3(a),
 either because no designation was in effect at the Participant's death
 or because a designation in effect at the Participant's death failed to
<PAGE>
 dispose of such amounts in their entirety, then for purposes of this
 Plan, the Participant's "Beneficiary" as to such undisposed of amounts
 shall be the Participant's estate.

     (b)  A "CHANGE OF CONTROL OF THE COMPANY" shall mean the happening
 of any of the following events:

          (1)  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 (A) the then outstanding Common Stock (the "Outstanding
     Company Common Stock") or (B) the combined voting power of the then
     outstanding voting securities of the Company entitled to vote
     generally in the election of directors (the "Outstanding Company
     Voting Securities"); excluding, however, the following: (i) any
     acquisition directly from the Company 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
     Company, (ii) any acquisition by the Company, (iii) any acquisition
     by any employee benefit plan (or related trust) sponsored or
     maintained by the Company or any entity controlled by the

                                    -2-

     Company, (iv) any acquisition pursuant to a transaction which
     complies with clauses (A), (B), and (C) of subparagraph (3) of this
     paragraph 3(b), (v) except as provided in paragraphs (iv) and (v),
     any acquisition by any of the Woodson Entities or any of the Smith
     Entities, or (vi) any increase in the proportionate number of
     shares of Outstanding Company Common Stock or Outstanding Company
     Voting Securities beneficially owned by a Person to 20% or more of
     the shares of either of such classes of stock if such increase was
     solely the result of the acquisition of Outstanding Company Common
     Stock or Outstanding Company Voting Securities by the Company;
     provided, however, that this clause (vi) shall not apply to any
     acquisition of Outstanding Company Common Stock or Outstanding
     Company Voting Securities not described in clauses (i), (ii),
     (iii), (iv), or (v) of this paragraph (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 Company
     Common Stock or Outstanding Company Voting Securities by reason of
     share purchases by the Company; or (2)  A change in the composition
     of the Board 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
     nomination for election by the Company's shareholders, was approved
     by a vote of at least a majority of those individuals who are
     members of the Board and who were also members of the Incumbent
     Board (or deemed to be such pursuant to this proviso) shall be

                                    -3-
<PAGE>
     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 (3)  Consummation of a reorganization, merger
     or consolidation, or sale or other disposition of all or
     substantially all of the assets of the Company or the acquisition
     of the assets or securities of any other entity (a "Corporate
     Transaction"); excluding, however, such a Corporate Transaction
     pursuant to which (A) all or substantially all of the individuals
     and entities who are the beneficial owners, respectively, of the
     Outstanding Company Common Stock and Outstanding Company Voting
     Securities immediately prior to such Corporate Transaction will
     beneficially own, directly or indirectly, more than 60% of,
     respectively, the outstanding shares of common stock and the
     combined voting power of the then outstanding voting securities
     entitled to vote generally in the election of directors, as the
     case may be, of the corporation resulting from such Corporate
     Transaction (including, without limitation, a corporation which as
     a result of such transaction owns the Company or all or
     substantially all of the Company's assets either directly or
     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 Company
     Common Stock and Outstanding Company Voting Securities, as the case
     may be, (B) no Person (other than the Company,

                                    -4-

     any employee benefit plan (or related trust) of the Company, 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
     Company prior to the Corporate Transaction, and (C) individuals who
     were members of the Incumbent Board will constitute at least a
     majority of the members of the board of directors of the Resulting
     Corporation; or (4)  The Woodson Entities acquire beneficial
     ownership of more than 35% of the Outstanding Company Common Stock
     or Outstanding Company 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 (5)  The Smith Entities acquire beneficial
     ownership of more than 35% of the Outstanding Company Common Stock
     or Outstanding Company Voting Securities or of the outstanding

     election of directors, as the case may be, of the Resulting
<PAGE>
     Corporation; or (6)  The approval by the shareholders of the

 An election by a Director to defer Directors' Fees pursuant to this

                                     -7-

 subparagraph (a) shall be effective with respect to Directors' Fees
 earned during the first fiscal year beginning after the date such

 (b) shall remain in effect until the last day of the fiscal year in
 which such election is made and during each subsequent fiscal year

<PAGE>
     (b)  Each Participant shall make an initial election at the time

 a new election with the Company specifying (1) the Account to which all
 Directors' Fees deferred subsequent to the last day of such fiscal year
 (and prior to the effective date of any subsequent election) shall be
 allocated and/or (2) the Account to which all or any portion of the
 balance of his Accounts as of the last day of such fiscal year shall be
 allocated.  The transfer of a Participant's Account balance shall be
 made in accordance with the following:

     (1)  in the case of a transfer from a Deferred Cash Account into a
     Deferred Stock Account, that portion of the balance in the
     Participant's Deferred Cash Account as of the last day of the
     fiscal year in which the Participant has made an election to
     transfer his Deferred Cash Balance shall be determined after giving
     effect to all other adjustments required by this Plan and such
     portion shall be debited from the Participant's Deferred Cash
     Account and credited to his Deferred Stock Account effective as of
     the first day of the next subsequent fiscal year.

     (2)  in the case of a transfer from a Deferred Stock Account into a
     Deferred Cash Account, the number of Stock Equivalent Units in the
     Participant's Deferred Stock Account as of the last day of the
     fiscal year to which the Participant has made an election to
     transfer his Deferred Stock Account shall be determined after

                                    -9-

     giving effect to all other adjustments required by this Plan and
     such Stock Equivalent Units shall be converted into cash equivalent
     by multiplying the number of such units by an amount equal to the
     per share Fair Market Value of the Common Stock on the last day of
     the fiscal year.  Effective as of the first day of the next
     subsequent fiscal year the Participant's Deferred Stock Account
     shall be debited by the number of Stock Equivalent Units so
     transferred and the Participant's Deferred Cash Account credited by
     the amount of cash equivalent so determined.  Any election made
     by a Participant in accordance with this paragraph 5 shall remain
     in effect until a new election filed by the Participant becomes
     effective.  A Participant's initial election shall be effective as
     of the date the Director becomes a Participant.  Notwithstanding
     any other provision of this Plan, no election pursuant to this
     paragraph 5 which changes the Account to which Directors' Fees
     deferred in a subsequent fiscal year are to be allocated or changes
     the Account to which any balance in such Participant's Accounts 
     shall be allocated shall be effective (1) until such election has
     been approved by the Board or (2) if it is made by a Participant
     within six months of the immediately preceding election filed by
     such Participant and any such election which shall not have been
     approved by the Board or which occurs within the period described
     in clause (2) shall be null and void.

     (c)  As of each date on which the Company shall make a payment of
 Director's Fees and a Participant has a deferral election then in
 effect, there shall be credited to such Participant's Deferred Cash
<PAGE>
 Account or Deferred Stock Account, as the case may be in accordance
 with such Participant's most recent effective election, the Directors'
 Fees otherwise payable to such Participant in cash as of such date.

                                     -10-

     (d)  Despite any other provision of this Plan, the most recent
 election in effect on December 17, 1997 made by a Participant with
 respect to the crediting of his Director's Fees to such Participant's
 Deferred Cash Account or Deferred Stock Account shall remain in effect
 as of December 17, 1997 until changed by such Director for a future
 fiscal year in accordance with the terms of the Plan.

     (e)  Within 90 days of the end of each fiscal year in which this
 Plan is in effect, the Company shall furnish each Participant a
 statement of the year-end balance in such Participant's Deferred Cash
 Account and Deferred Stock Account.

     (f)  Effective as of March 31, 1998, each participant in the
 Mosinee Paper Corporation Deferred Compensation Plan for Directors as
 in effect on March 31, 1998 (the "Mosinee Plan") shall become a
 Participant in the Plan (a "Mosinee Participant") and (1) the Deferred
 Cash Account created in the name of each such Mosinee Participant
 pursuant to paragraph 5(a) shall be credited with the balance, if any,
 of such Mosinee Participant's Deferred Cash Account in the Mosinee Plan
 as of March 31, 1998 and such Mosinee Participant's Deferred Cash
 Account in the Mosinee Plan shall thereafter be represented by the
 Deferred Cash Account established hereunder and shall be subject to all
 terms and conditions of this Plan and (2) the Deferred Stock Account
 created in the name of each such Mosinee Participant pursuant to
 paragraph 5(a) shall be credited with the balance, if any, of such
 Mosinee Participant's Deferred Stock Account in the Mosinee Plan as of
 March 31, 1998 and such Mosinee Participant's Deferred Stock Account in
 the Mosinee Plan shall thereafter be represented by the Deferred Stock
 Account established hereunder and shall be subject to all terms and
 conditions of this Plan.  The Deferred Cash Account and the Deferred
 Stock Account of any Mosinee Participant who is, on March 31,

                                     -11-

 1998, or who thereafter becomes, a Participant by virtue of being a
 Director shall be combined with and maintained as one account with,
 respectively, the Deferred Cash Account and the Deferred Stock Account
 maintained for such Director with respect to his Directors' Fees.

     6.   FORM FOR ELECTIONS.  The Secretary of the Company shall
 provide election forms for use by Directors in making an initial
 election to become a Participant and for making all other elections or
 designations permitted or required by the Plan.

     7.   DEFERRED CASH ACCOUNT.  As of the last day of each fiscal
 quarter, there shall be computed, with respect to each Deferred Cash
 Account which is then in existence, an amount equal to interest on the
 average daily balance in such Account during such quarter, computed at
 a rate per annum equal to the prime rate of interest then in effect at
 The Chase Manhattan Bank of New York.  The amount so determined shall
 be credited to and become part of the balance of such Account as of the
 first day of the next fiscal quarter.
<PAGE>
     8.   DEFERRED STOCK ACCOUNT.

     (a)  As of each date on which the Company shall make a payment of
 Director's Fees and a Participant has a deferral election then in
 effect which provides for the deferral of payment of such fees to the
 Participant's Deferred Stock Account, the Directors' Fees otherwise
 payable to such Participant in cash as of such date shall be converted
 into that number of "Stock Equivalent Units" (rounded to the nearest
 one-ten thousandth of a unit) determined by dividing the amount of such
 Directors' Fees by an amount equal to the per share Fair Market Value
 of the Common Stock on such date.

     (b)  On each date on which a dividend payable in cash or property
 is paid on the Common Stock, there shall be credited to each Deferred
 Stock Account such number of additional Stock Equivalent Units as are

                                     -12-

 determined by dividing (1) the amount of the cash or other dividend
 which would have then been payable on the number of shares of Common
 Stock equal to the number of Stock Equivalent Units (including
 fractional shares) then represented in such Account by (2) an amount
 equal to the per share Fair Market Value of the Common Stock on such
 date.  If the date on which a dividend is paid on the Common Stock is
 the same date as of which Directors' Fees are to be converted into
 Stock Equivalent Units, the dividend equivalent to be credited to such
 Account under this paragraph 8 shall be determined after giving effect
 to the conversion of the credit balance in such Account into Stock
 Equivalent Units.

     (c)  The number of Stock Equivalent Units credited to a
 Participant's Deferred Stock Account shall be adjusted (to the nearest
 one-ten thousandth of a unit) to reflect any change in the Common Stock
 resulting from a stock dividend, stock split-up, combination,
 recapitalization or exchange of shares, or the like.

      9.  DISTRIBUTION OF DEFERRED AMOUNTS.

     (a) Distribution of amounts represented in a Participant's Deferred
 Cash Account or a Deferred Stock Account shall be made in accordance
 with the following:

     (1)  Payment of the balance of the Deferred Cash Account and
     Deferred Stock Account of a Participant whose Termination of
     Service occurs for a reason other than death and prior to a Change
     of Control of the Company shall be made in a lump sum as of the
     last day of the fiscal quarter coincident with or immediately
     subsequent to the Participant's Termination of Service unless the
     Participant elects otherwise in accordance with the provisions of
     paragraph 9(b).

                                     -13-

     (2)  In the event a Participant ceases to be a Director because of
     his death or in connection with a Change of Control of the Company,
     payment of the balance of his Deferred Cash Account and Deferred
     Stock Account shall be made in a lump sum as of the last day of the
<PAGE>
     fiscal quarter coincident with or immediately subsequent to the
     Participant's Termination of Service.

     (b)  A Participant may elect, (1) before the first day of each
 fiscal year, (2) subject to the automatic distribution provisions of
 paragraph 9(a)(2), which shall govern the distribution of benefits in
 the event of Termination of Service which occurs because of death or a
 Change of Control of the Company, and (3) prior to his Termination of
 Service that payment of the balance of his Deferred Cash Account and
 Deferred Stock Account shall be made in installments and the:

     (A)  fiscal quarter in which distribution of the Participant's
     Accounts shall begin (but in no event (i) earlier than the
     Director's Termination of Service or (ii) later than the earlier
     of (a) the Director's 70th birthday or (b) the date five years
     after the date of the Director's Termination of Service; and
     (B)  number of fiscal quarters over which such Accounts shall be
     distributed to the Participant, which period shall not extend
     beyond the end of the 40th fiscal quarter following the fiscal
     quarter in which such distribution begins.

 Any election filed pursuant to this paragraph 9(b) shall be effective
 as of the first day of the first fiscal year which begins next
 subsequent to the fiscal year in which (1) such election has been made
 and (2) such election has been approved by the Board.

     (c)  If installment payments were elected by the Participant
 pursuant to paragraph 9(b), distributions shall be made in quarterly
 installments beginning on the first day of the first fiscal quarter

                                    -14-

 following the date on which such Participant's Termination of Service
 occurs or each other later fiscal quarter as the Participant may have
 specified.

     (1)  In the case of a Deferred Cash Account with respect to which
     installment payments were elected, the amount of each quarterly
     installment shall be determined by dividing the credit balance in
     such Account as of the distribution date by the number of
     installments then remaining unpaid.  The credit balance in such
     Account shall then be reduced by the amount of each distribution
     out of such Account.

     (2)  In the case of a Deferred Stock Account with respect to which
     installment payments were elected, the amount to be distributed as
     each quarterly installment shall be determined as follows:  (A)
     multiply the number of Stock Equivalent Units (including any
     fraction thereof) then reflected in such Account by the Fair Market
     Value of the Common Stock on such date; (B) add to the product so
     determined the amount (if any) which has been credited to such
     Account but which has not been converted into Stock Equivalent
     Units; and (C) divide the total so obtained by the number of
     installments then remaining unpaid. The number of Stock Equivalent
     Units represented in a Deferred Stock Account shall be reduced
     forthwith by that number (rounded to the nearest one-ten thousandth
     of a unit) determined by dividing the amount of the distribution by
<PAGE>
    the Fair Market Value of the Common Stock taken into account for
 purposes of clause (A) of the preceding sentence.

 In the event that a Participant dies after receiving payment of some,
 but less than all, of the entire amount to which such Participant is
 entitled under this Plan, the unpaid balance shall be paid in a lump
 sum to the Participant's Beneficiary.

                                     -15-

     (d)  In the case of a Deferred Cash Account or a Deferred Stock
 Account with respect to which payment is to be made in a lump sum, the
 amount of such payment shall be determined as if installment payments
 had been elected and the lump sum was the last (but only) such payment.

     (e)  After a Participant's Termination of Service occurs, neither
 such Participant or his Beneficiary shall have any right to modify in
 any way the schedule for the distribution of amounts credited to such
 Participant under this Plan as specified in the last election filed by
 the Participant.  However, upon a written request submitted to the
 Secretary of the Company by the person then entitled to receive
 payments under this Plan (who may be the Participant, or a
 Beneficiary), the Board may in its sole discretion, accelerate the time
 for payment of any one or more installments remaining unpaid.

     10.  INCOMPETENCY.  If, in the opinion of the Board, a Participant
 shall at any time be mentally incompetent, any payment to which such
 Participant would be entitled under this Plan may, with the approval of
 the Board, be paid to the Participant's legal representative, or to any
 other person for his benefit and in such case, the Board may in its 
 sole discretion, accelerate the time for payment of any one or more
 installments remaining unpaid.

     11.  MISCELLANEOUS.

     (a)  This Plan shall be effective upon adoption by the Board.

     (b)  Amounts payable hereunder may not be voluntarily or
 involuntarily sold or assigned, and shall not be subject to any
 attachment, levy or garnishment.

     (c)  Participation in this Plan by any person shall not confer upon
 such person any right to be nominated for re-election to the Board, or
 to be re-elected to the Board.

                                     -16-

     (d)  The Company shall not be obligated to reserve or otherwise set
 aside funds for the payment of its obligations hereunder, and the
 rights of any Participant under the Plan shall be an unsecured claim
 against the general assets of the Company.  All amounts due
 Participants or Beneficiaries under this Plan shall be paid out of the
 general assets of the Company.

     (e)  The Board shall have all powers necessary to administer this
 Plan, including all powers of Plan interpretation, of determining
 eligibility, and the effectiveness of elections, and of deciding all
<PAGE>
 other matters relating to the Plan; provided, however, that no
 Participant shall take part in any discussion of, or vote with respect
 to, a matter of Plan administration which is personal to him, and not
 of general applicability to all Participants.  All decisions of the
 Board shall be final as to any Participant under this Plan.

     (f)  The Board may amend this Plan in any, and all respects at any
 time, or from time to time, or may terminate this Plan at any time, but
 any such amendment or termination shall be without prejudice to any
 Participant's right to receive amounts previously credited to such
 Participant under this Plan.

                     MOSINEE PAPER CORPORATION
                 1985 EXECUTIVE STOCK OPTION PLAN

                     As amended March 4, 1999

                       MOSINEE PAPER CORPORATION
                   1985 EXECUTIVE STOCK OPTION PLAN

          1.   PURPOSE.  The Mosinee Paper Corporation 1985 Executive
 Stock Option Plan (the "Plan") is intended to attract and retain key
 executive employees by permitting such employees of Mosinee Paper
 Corporation (the "Company") or any parent or subsidiary of the Company
 to acquire authorized and unissued, or reacquired, shares of common
 stock, $2.50 par value, of the Company ("Stock") pursuant to purchase
 options.  The availability of the options and grants thereof will
 furnish additional inducements to such employees to continue employment
 with the Company, or any parent or subsidiary of the Company, and
 encourage them, by giving them an opportunity to acquire a greater
 stake in the Company's success, to increase their efforts to promote
 the best interests of the Company and its stockholders.  Subject to the
 provisions of the Plan, there may be granted options containing such
 terms and conditions as shall be requisite to constitute them
 "nonqualified stock options," i.e., options which are not "incentive
 stock options" within the meaning of Section 422A of the Internal
 Revenue Code of 1954, as amended (the "Code").  A key employee may be
 granted and may hold one or more nonqualified stock options under this
 Plan.

          2.   ELIGIBLE EMPLOYEES.  The persons eligible to receive
 options under the Plan shall be key executive employees (who may also
 be officers or directors) of the Company or any parent or subsidiary of
 the Company and who are selected by the Executive Compensation & Bonus

                                     -1-
<PAGE>
 Committee (the"Committee") designated by the Board of Directors of the
 Company (the "Board").  Directors of the Company or any parent or
 subsidiary of the Company who are not also employees of the Company
 or any parent or subsidiary of the Company shall not be eligible to
 receive options under the Plan.

     3.   TIME AND MANNER OF GRANTING OPTIONS.  From and after the
 Effective Date of the Plan (as defined in Section 16 hereof) and
 continuing to the close of business on the tenth anniversary of such
 Effective Date, the Committee may, at such time or times as the
 Committee may determine, grant to any one or more eligible employees
 ("Optionees") nonqualified stock options, each such option to cover the
 purchase of such number of shares of Stock upon such terms and
 conditions not inconsistent with the Plan as the Committee shall from
 time to time determine.

          No person shall have any right to an option or any other right
 under the Plan unless and until an option shall be granted to such
 person by the Committee.  Subject to the provisions of Section 9
 hereof, no more than 90,000 shares of Stock shall be sold pursuant to
 the exercise of all options granted hereunder.  Any shares for which an
 option is granted hereunder which for any reason are released from such
 option by expiration or termination thereof or otherwise shall be
 available for reoptioning under this Plan.  The Company shall,
 forthwith upon the granting of an option, mail or deliver to the
 Optionee a copy of the Plan and an option certificate evidencing such
 option.  Option certificates shall be in such

                                     -2-

 form and shall contain such terms and provisions not inconsistent with
 the Plan as the Committee shall deem appropriate.

          4.   TERM OF OPTIONS.  In no event shall any stock option
 granted under the Plan be exercisable after the expiration of twenty
 years from the date such option is granted.

          5.   TERMS AND CONDITIONS.

          (a)  Nonqualified stock options granted under this Plan
 shall contain such provisions, not inconsistent with this Plan, as
 may be deemed advisable by the Committee.

          (b)  The option price per share of Stock under any
 nonqualified stock option granted hereunder shall be not less than one
 hundred per cent (100%) of the fair market value of one share of Stock
 on the date such option is granted.

          6.   MANNER OF EXERCISE OF OPTIONS.

          (a)  Subject to the provisions of Section 8 hereof, each
 option granted hereunder shall become exercisable on the date specified
 in the option agreement but in no event earlier than six months after
 the date of grant.  Any shares with respect to which an option becomes
 exercisable shall remain available for purchase by exercise of the
 option in accordance with its terms at any time or from time to time
 before the option expires.
<PAGE>
          (b)  Exercise shall be effected only by delivery to the
 Company of an irrevocable written notice of the Optionee's election
 to exercise the option with respect to a specified whole number of
 shares of Stock. Such exercise must be followed within five (5)

                                     -3-

 business days by payment in cash to the Company of (i) the amount of
 the option purchase price for the number of shares of Stock as to which
 the option is then being exercised and (ii) the amount of any
 applicable federal or state withholding taxes.  The Optionee's failure
 to so pay shall result in the forfeiture of his rights under the Plan
 for the number of shares specified in the notice.  No option may be
 exercised with respect to a fractional share of Stock.

          7.   NON-TRANSFERABILITY.  Options granted hereunder shall not
 be transferable by an Optionee otherwise than by will or the laws of
 descent and distribution and may, during the lifetime of an Optionee,
 be exercised only by such Optionee.

          8.   EXERCISE AFTER TERMINATION OF EMPLOYMENT.

          (a)  For purposes of the Plan and each option granted under
 the Plan, an Optionee's employment shall be deemed to have terminated
 at the close of business on the day preceding the first date on which
 he is no longer for any reason whatsoever employed by the Company or
 by any parent or subsidiary of the Company, provided that the Committee
 may determine in one or more particular cases that a leave of absence
 granted by the employing corporation shall not result in the
 termination of an Optionee's employment.

          (b)  If an Optionee's employment is terminated by his
 voluntary resignation or if he is discharged for cause, any option held
 by the Optionee shall expire on the date of such termination.  For
 purposes of this section, "for cause" shall mean affirmative acts in

                                     -4-

 violation of federal, state, or local criminal law.

          (c)  If an Optionee dies while such Optionee is an employee of
 the Company or any parent or subsidiary of the Company or within three
 months after his termination of employment for a reason other than
 voluntary resignation or discharge for cause, any option held by such
 Optionee at the date of the Optionee's death may be exercised by such
 Optionee's estate or the person to whom such option is transferred by
 will or the applicable laws of descent and distribution with respect to
 all or any part of that number of shares of Stock as to which such
 option was exercisable by the Optionee immediately before his death but
 only if the date of exercise is both within 20 years from the Date of
 Grant (or such shorter period in which the option would have expired if
 the Optionee had lived and remained in the Company's employ) and within
 one year after the date of the Optionee's death.  In the event an
 Optionee has attained his Retirement Date (as defined herein), (i) the
 provisions of Section 8(b) and of the preceding sentence shall not be
 applicable to such Optionee's nonqualified stock options and (ii) any
 nonqualified stock option held by such Optionee at the date of the
<PAGE>
 Optionee's death may be exercised by such Optionee's estate or the
 person to whom such option is transferred by will or the applicable
 laws of descent and distribution with respect to all or any part of
 that number of shares of Stock as to which such option was exercisable
 by the Optionee immediately before his death but only if the

                                     -5-

 date of exercise is both within 20 years from the Date of Grant (or
 such shorter period in which the option would have expired if the
 Optionee had lived and remained in the Company's employ) and on or
 before the second anniversary of the Optionee's Retirement Date.  For
 purposes of this Plan, the term "Retirement Date" shall mean the date
 on which the Optionee's employment with the Company (and any parent or
 subsidiary of the Company) terminates (including termination because of
 death) for a reason other than cause if the Optionee had then attained
 age 55 and completed ten calendar years of service with the Company
 (or any parent or subsidiary of the Company).

          (d)  If an Optionee's employment is terminated for any reason
 other than voluntary resignation, discharge for cause or death, any 
 option held by the Optionee may be exercised at any time which is both
 before the time the option would otherwise expire and within three
 months after the date of such cessation of employment, but only with
 respect to that number of shares of Stock which the Optionee would have
 been permitted to purchase under his option immediately before the date
 of termination of such Optionee's employment.  In the event an Optionee
 has attained his Retirement Date, (i) the provisions of Section 8(b)
 and of the preceding sentence shall not be applicable to such
 Optionee's nonqualified stock options and (ii) such Optionee's
 nonqualified stock options may be exercised at any time which is both
 before the time the option would

                                     -6-

 otherwise expire and on or before the second anniversary of the
 Optionee's Retirement Date, but only with respect to that number of
 shares of Stock which the Optionee would have been permitted to
 purchase under his option immediately before the date of termination of
 such Optionee's employment.

          9.   ADJUSTMENTS FOR CHANGES IN CAPITALIZATION, ETC.  If the
 Company shall, after the Effective Date, change its Stock into a
 greater or lesser number of shares through a stock dividend, stock
 split-up or combination of shares, then        

  (i)  the number of shares of Stock then subject to the Plan but
               which are not then subject to any outstanding option;
         (ii)  the number of shares of Stock subject to each then
               outstanding option or (to the extent not previously
               exercised); and

        (iii)  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
<PAGE>
               in order to give effect thereto.  Notwithstanding any
               such proportionate increase or decrease, no fraction of a
               share of Stock shall be issued upon the exercise of an
               option.  If any split-up or combination of shares shall
               involve a change of par value, the shares of Stock
               subject to options theretofore or

                                     -7-

               thereafter granted shall be the shares of Stock as so
               changed.

          If, after the Effective Date, there shall be any change in the
 Stock of the Company other than through a stock dividend, stock 
 split-up or combination of shares, then if (and only if) the Committee
 shall determine that such change equitably requires an adjustment in
 the number or kind or option price of shares of Stock then subject to
 an option, or the number or kind of shares 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 option and the Plan.
 If any member of the Board shall, at the time of such approval, be an
 Optionee, he shall not participate in action in connection with such
 adjustment.

          10.  ADMINISTRATION OF THE PLAN.

          (a)  The Plan shall be administered by the Committee, which
 shall consist of three or more persons selected by the Board from its
 members.  The Committee shall have authority to determine who are, from
 time to time, eligible employees, to construe the Plan, to prescribe,
 amend and rescind rules and regulations for the administration of the
 Plan, to amend or modify the Plan in such manner as the Committee deems
 required to make the Plan conform to the provisions of any federal or
 state laws, or regulations issued thereunder, or practically workable,
 and to take any other action necessary or advisable for the effective

                                     -8-

 administration of the Plan; provided, however, that no such amendment
 or modification of the Plan shall affect the provisions of any option
 granted before such amendment or modification to the detriment of any
 Optionee unless such amendment or modification is required to comply
 with any applicable law or regulation, and provided, further, that any
 such amendment of the Plan extending the period within which options
 may be granted under the Plan, or increasing the number of shares of
 Stock to be optioned under the Plan (except as provided in Section 9
 hereof), or reducing the minimum purchase price per share provided in
 the Plan (except as provided in Section 9 hereof), or changing the
 class of employees to whom options may be granted under the Plan shall,
 in each case, be subject to approval by the Board.  Decisions of the
 Committee shall be final.  Members of the Committee may be removed by
 the Board.  Vacancies in the Committee may be filled, and additional
 members may be appointed from time to time by the Board.  The decision
 of a majority in number of the members of the Committee, from time to
 time acting, shall be deemed to be the decision of the Committee, and a
<PAGE>
 majority in number of members of the Committee, from time to time
 acting, shall constitute a quorum of the Committee for the transaction
 of any business.  No member of the Committee may be an individual who
 is or has been for at least one year prior to selection to the
 Committee, eligible for participation in the Plan.

          (b)  The authority granted the Board of Directors in this
 section of the Plan shall be exercised solely by those directors who
                                     -9-

 are not, and have not been for at least one year prior to such
 exercise, eligible for participation in the Plan.

          11.  STOCKHOLDERS' RIGHTS UPON EXERCISE.  An Optionee shall
 not, by reason of the Plan or any option granted pursuant to the Plan,
 have any rights of a stockholder of the Company; however, upon each
 exercise of an option under the Plan, the Optionee shall have, with
 respect to the number of shares of Stock as to which such option is
 then being exercised, all rights of a stockholder of record from the
 date of such exercise, irrespective of whether certificates to evidence
 the shares of Stock with respect to which the option was exercised
 shall have been issued on such date.

          12.  THE RIGHT OF EMPLOYER TO TERMINATE EMPLOYMENT.  Nothing
 contained in the Plan or in any option granted pursuant to the Plan
 shall confer upon any Optionee any right to be continued in the
 employment of the Company, or any parent or subsidiary of the Company,
 or interfere in any way with the right of such Optionee's employer to
 terminate his employment at any time with or without cause.

          13.  GOVERNMENT APPROVALS.  If at any time the Company shall
 be advised by its counsel that the exercise of any option or the
 delivery of shares of Stock upon the exercise of an option is required
 to be approved, registered or qualified under any applicable law, or
 must be accompanied or preceded by a prospectus or similar circular
 meeting the requirements of any applicable law, the Company will use

                                     -10-

 its best efforts to obtain such approval, to effect such registrations
 and qualifications, or to provide such prospectus or similar circular
 within a reasonable time, but exercise of the options or delivery by
 the Company of certificates for shares of Stock may be deferred until
 such approvals, registrations or qualifications are effected, or until
 such prospectus or similar circular is available.

          14.  DISCONTINUANCE OF THE PLAN.  The Board may decrease the
 number of shares issuable under the Plan or discontinue and terminate
 the Plan at any time, but no such decrease, discontinuance or
 termination shall affect any options granted before such decrease,
 discontinuance or termination.

<PAGE>
 or consolidating into another corporation, or from selling or
 transferring all or substantially all of its assets, or from
 distributing all or substantially all of its assets to its stockholders
 in liquidation, or from dissolving and terminating its corporate
 existence; and in any such event (other than a merger in which the
 Company is the surviving corporation and after which the Company
 remains an independent, publicly held corporation), the Company or any
 surviving party to any such merger, consolidation, or sale or transfer
 of assets may provide by resolution of its Board of Directors that all
 rights of the person or persons entitled to exercise then outstanding
 options granted under the Plan, and such options, shall wholly and
 completely terminate at the time of any such

                                     -11-

 merger, consolidation, sale or transfer of assets, liquidation, or
 dissolution, except that adequate provision for such person or persons
 shall be made in accordance with paragraph (b) below.

          (b)  In the event that (i) any individual, corporation,
 partnership or other person or group of persons or entities becomes the
 beneficial owner, directly or indirectly, of 45% or more of the
 Company's then outstanding Common Stock ("Change in Control") or (ii)
 any merger, consolidation, liquidation, dissolution or termination
 after which the Company will not survive as an independent,
 publicly-owned corporation or any sale or transfer of all or
 substantially all of the Company's assets ("Reorganization") occurs,
 then the Company shall pay with respect to each outstanding option
 under this Plan an amount equal to (x) the difference between the Fair
 Market Value (as defined in (c) below) and exercise price of the
 option, multiplied by (y) the number of shares of Stock subject to
 such option.  Such payment shall be made in cash within 30 days after,
 in the case of a Reorganization requiring approval by the Company
 stockholders, the date of such approval and, in the case of a Change in
 Control, the date upon which such change occurs.

          (c)  Solely for purposes of (b) above, "Fair Market Value"
 shall mean the greater of (i) the highest price per share of the
 Company's Common Stock (x) paid by the acquiring person within twelve
 months of the occurrence of the Change in Control to effect such change

                                     -12-

 or (y) provided for in any agreement for the Reorganization or
 (ii) fair market value determined in accordance with Section 17
 of this Plan.

          16.  EFFECTIVE DATE OF PLAN,  The Plan has been adopted by the
 Board on June 27, 1985, and the Plan shall be deemed to have become
 effective on such date.

          17.  MISCELLANEOUS.

          (a)  The transfer of an employee from the Company to a parent
 or subsidiary of the Company or from a parent or subsidiary of the
 Company to the Company or another parent or subsidiary of the Company
 shall not be a termination of employment or an interruption of
 continuous employment for the purposes of the Plan.
<PAGE>
          (b)  As used in the Plan, the terms "parent" and "subsidiary"
 shall have the meanings ascribed to them in Sections 421, 422A and 425
 of the Code.

          (c)  Except as otherwise provided, for purposes of this Plan,
 the fair market value of a share of Stock on a specified day shall be
 the mean between the high and low sale price per share as reported for
 such day (or if such day is not a business day, for the immediately
 preceding business day) on a national stock exchange, or if the Stock
 is not listed on such an exchange, on the NASDAQ national market
 system.

          (d)  No option or shares of Stock issuable under the Plan shall
 be transferable or assignable either by the voluntary or involuntary act
 of the Optionee or by operation of law, or be liable for any debts or

                                     -13-

 liabilities of the Optionee, except as provided herein.

     Section 18.  Notwithstanding any other provision of this Plan or of
 any option agreement relating to any option granted hereunder, the

 other transaction described in Section 11(b) of this Plan and of any
 corresponding or similar provision of any such option agreement.  
 Without limiting the generality of the foregoing, the consummation of
 such transactions shall not result in the payment of any cash to any
 holder of an option granted under this Plan.

 families and their respective descendants (the "Smith Family"), heirs

                                     -17-

 "Associate" shall have the meanings ascribed to such terms in Rule
 12b-2 of the General Rules and Regulations under the Exchange Act as in
 effect on the date of this Plan.

     (b)

     (i) In the event of a Change in Control,

          (A)  all options outstanding on the date on which such Change
     in Control has occurred (the "Change in Control Date") shall, to 
     the extent not then exercisable or vested, immediately become
     exercisable in full, and

          (B)  each Optionee may elect, with respect to each option held
     by such Optionee on the Change in Control Date (the Optionee's 
     "Election Right"), to surrender such option for an immediate lump
     sum cash payment in an amount equal to the product of (1) the
     number of shares of common stock of the Corporation (for purposes
     of this Section 15(b), "Shares") then subject to the option as to
     which the election is being exercised, multiplied by (2) the
     excess, if any, of (a) the greater of (i) the Change in Control
     Price or (ii) the highest fair market value of a Share on any day
     in the 60-day period ending on the Change in Control Date, over (b)
     the option price of such option.  For purposes of this Section
     15(b), 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 15(a)(iii), the highest price
     per Share paid in such tender or exchange offer or Corporate 
     Transaction.  To the extent that the consideration paid in any such
     transaction consists all or in part of securities or other noncash
<PAGE>
     consideration, the value of such securities or other noncash

                                     -18-

     consideration shall be determined in the sole discretion of the
     Committee.

 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
 Corporation 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 Corporation's home office on or before the 60th day
 following the Change in Control Date.

     (iii) All payments due an Optionee pursuant to the provisions of
 this Section 15(b) shall be made by the Corporation on or before the
 5th business day following the date on which the Optionee's election
 has been delivered to the Corporation pursuant to Section 15(b)(ii).

     (iv)  Notwithstanding any other provision of this Section 15(b), if
 the grant or the exercise of an Optionee's Election Right or payment of
 cash provided for in Section 15b)(i) would make a Change in Control
 transaction ineligible for pooling-of-interests accounting treatment
 under APB No. 16, that, but for the nature of such grant or exercise of
 Election Rights or payment of cash, would otherwise be eligible for
 such pooling-of-interests accounting treatment, the Committee shall
 have the right and authority to substitute for the cash payments to be
 made to the Optionee pursuant to Section 15(b)(ii), Shares with a fair
 market value, determined as of the date of delivery of such Shares,
 equal to the cash that would otherwise be payable to such Optionee in
 connection with the exercise of an Optionee's Election Right hereunder
 or, to the extent necessary to preserve such pooling-of-interests
 accounting treatment, to otherwise modify, eliminate, or terminate such
 Election Right.

                     MOSINEE PAPER CORPORATION
                1988 STOCK APPRECIATION RIGHTS PLAN

                     As amended March 4, 1999

                     MOSINEE PAPER CORPORATION
                1988 STOCK APPRECIATION RIGHTS PLAN


     1.   PURPOSE.

          The purpose of the Mosinee Paper Corporation 1988 Stock
 Appreciation Rights Plan (the "Plan") is to attract and retain
 outstanding individuals as officers and key employees of Mosinee Paper
<PAGE>
 Corporation (the "Corporation") and its subsidiaries, and to furnish
 incentives to such individuals through rewards based upon the
 performance of the common stock of the Corporation.  To this end,
 the Committee hereinafter designated may grant stock appreciation
 rights to officers and other key employees of the Corporation and its
 subsidiaries, on the terms and subject to the conditions set forth in
 this Plan.

     2.   PARTICIPANTS.

          Participants in the Plan shall consist of such officers and
 other key employees of the Corporation and its subsidiaries as the
 Committee in its sole discretion may select from time to time to
 receive stock appreciation rights.

     3.   ADMINISTRATION OF THE PLAN.

          The Plan shall be administered by a Committee (the
 "Committee") of at least three members appointed by the Board of
 Directors of the Corporation from among its members.  No person shall
 be appointed a member of the Committee if, during the one year prior to
 the date on which such person's service as a member of the Committee is
 to commence, such person was granted or awarded equity securities of
 the Corporation (within the meaning of Securities and Exchange
 Commission Rule 16a-1(d)) under the Plan or any other plan of the
 Corporation or any subsidiary of the Corporation.  Subject to the
 provisions of the Plan, the Committee shall

                                     -1-

 have authority (i) to determine which employees of the Corporation and
 its subsidiaries shall be eligible for participation in the Plan; (ii)
 to select employees to receive grants under the Plan; (iii) to
 determine the number of stock appreciation rights subject to the grant,
 the time and conditions of exercise or vesting, the fair market value
 of the common stock of the Corporation for purposes of the Plan, and
 all other terms and conditions of any grant; and (iv) to prescribe the
 form of agreement, certificate or other instrument evidencing the
 grant.  The Committee shall also have authority to interpret the Plan
 and to establish, amend and rescind rules and regulations for the
 administration of the Plan, and all such interpretations, rules and
 regulations shall be conclusive and binding on all persons, provided,
 however, that the Committee shall not exercise such authority in a
 manner adversely and significantly affecting rights previously granted
 unless the action taken is required to comply with any applicable law
 or regulation.

     4.   EFFECTIVE DATE AND TERM OF PLAN.

          The Plan shall become effective on June 16, 1988, the date of
 its approval by the Board of Directors of the Corporation.  The Plan
 shall terminate ten years after it becomes effective, unless terminated
 sooner by action of the Board of Directors.  No further grants may be
 made under the Plan after its termination, but the termination of the
 Plan shall not affect the rights of any participant under, or the
 authority of the Committee with respect to, any grants made prior to
 termination.
<PAGE>
     5.   SHARES SUBJECT TO THE PLAN.

          Subject to adjustment as provided in paragraph 7 hereof, the
 aggregate number of shares of common stock of the Corporation with
 respect to which stock appreciation rights may be granted under the

                                     -2-

 Plan shall not exceed 350,000.  Whenever a stock appreciation right
 granted under the Plan can no longer under any circumstances be
 exercised, the shares, if any, then remaining subject to such stock
 appreciation right shall thereupon be released from such stock
 appreciation right and shall thereafter be available for additional
 grants of stock appreciation rights under the Plan.

     6.   STOCK APPRECIATION RIGHTS.

          (a)  GRANTS.  Stock appreciation rights entitling the grantee
 to receive cash equal to the sum of (i) the appreciation in value of
 and (ii) the value of the reinvested cash dividends which would have
 been paid with respect to a stated number of shares of common stock of
 the Corporation between the date of grant and the date of exercise (the
 "hypothetical reinvested cash dividends") may be granted from time to
 time to such officers and other key employees of the Corporation and
 its subsidiaries as may be selected by the Committee.

          (b)  TERMS OF GRANT.  Stock appreciation rights shall be
 exercisable in whole or in such installments and at such times as may
 be determined by the Committee, provided that no stock appreciation
 right shall be exercisable more than twenty years after the date of
 grant.  The Committee may at the time of grant or at any time
 thereafter impose such additional terms and conditions on the exercise
 of stock appreciation rights as it deems necessary or desirable for
 compliance with Section 16(a) or 16(b) of the Securities Exchange Act
 of 1934 and the rules and regulations thereunder.

          (c)  TERMINATION OF EMPLOYMENT OR DEATH.  If a grantee ceases
 to be employed by the Corporation and any of its subsidiaries for any
 reason other than death or attaining his Retirement Date, any stock
 appreciation right held by such grantee may be exercised for a period

                                    -3-

 ending on thee arlier of the 90th day following the date of such
 cessation of employment or the date of expiration of such stock
 appreciation right, but only with respect to that number of shares of
 common stock for which such right was exercisable immediately prior to
 the date of cessation of employment.

     If a grantee ceases to be employed by the Corporation or any of
 its subsidiaries by reason of death prior to his Retirement Date, or
 dies within 90 days after termination of his employment by the
 Corporation or any of its subsidiaries prior to his having attained
 his Retirement Date, any stock appreciation right held by such grantee
 may be exercised, with respect to all or any part of the common stock
 of the Corporation with respect to which such stock appreciation right
<PAGE>
 was exercisable by the grantee immediately prior to his death, for a
 period ending on the first anniversary of the date of such grantee's
 death.

     If a grantee attains his Retirement Date, any stock appreciation
 right held by such grantee may be exercised for a period ending on the
 second anniversary of such Retirement Date, but only with respect to
 that number of shares of common stock for which such right was
 exercisable immediately prior to the date of cessation of employment.

     Notwithstanding any other provision of this Section 6(c), no stock
 appreciation right shall be exercisable after the first to occur of (1)
 the date specified in Section 6(b) or (2) the date specified by the
 Committee in the grant evidencing such rights.

      For purposes of this Plan, the term "Retirement Date" shall mean
 the date on which the grantee's employment with the Corporation (and
 any parent or subsidiary of the Corporation) terminates (including
 termination because of death) if the Optionee had then attained age 55

                                     -4-

 and completed ten calendar years of service with the Corporation (or
 any parent or subsidiary of the Corporation).

          (d)  PAYMENT ON EXERCISE.  Upon exercise of a stock
 appreciation right the grantee shall be paid within five business days
 an amount in cash equal to the sum of (i) the amount by which the fair
 market value of one share of the Corporation's common stock on the date
 of exercise exceeds the date of grant value thereof multiplied by the
 number of shares in respect of which the stock appreciation right is
 being exercised and (ii) the value of the hypothetical reinvested cash
 dividends associated therewith.  The value of the hypothetical
 reinvested cash dividends associated with a share in respect of which
 the stock appreciation right is being exercised (the "exercised share")
 shall be equal to the fair market value on the date of exercise of the
 number of additional shares (or fraction thereof) of the Corporation's
 common stock the grantee would have owned if it is assumed (1) that
 cash dividends which would have been paid with respect to the exercised
 share if the exercised share had been outstanding from the time of
 grant had been paid in cash to the grantee and then immediately
 reinvested by the grantee in the Corporation's common stock at the fair
 market value thereof on the applicable dividend payment date, and (2)
 that, once assumed issued, hypothetical shares resulting from assumed
 dividend reinvestment themselves paid cash dividends (at the same time
 and in the same amount as shares of the Corporation's outstanding
 common stock) which were reinvested in a similar manner.

          For purposes of this paragraph, the fair market value of a
 share of common stock of the Corporation means:

                                     -5-

               (A)  The mean between the high and low prices at which 
     the common stock of the Corporation was traded if the common stock
     of the Corporation was then listed for trading on a national or regional
<PAGE>
     securities exchange; or

               (B)  The mean between the published high and low prices
     of the common stock of the Corporation if the common stock of the
     Corporation was then traded on a bona fide over-the-counter market;
     or (C)  If the common stock of the Corporation was not traded
     on an exchange or on a bona fide over-the-counter market, a value
     determined by an appraiser selected by the Committee.

 In the event that the date of the exercise of a stock appreciation
 right is a date on which there is no trading of the common stock of the
 Corporation on a national or regional securities exchange or is a date
 for which there is no published bid and asked prices if the stock is
 traded on the over-the-counter market, such fair market value shall be
 determined by referring to the next preceding business day on which
 trading occurs or on which published prices are available.

          (e)  ADDITIONAL TERMS AND CONDITIONS.  The agreement or
 instrument evidencing the grant of stock appreciation rights may
 contain such other terms, provisions and conditions not inconsistent
 with the Plan as may be determined by the Committee in its sole
 discretion.

     7.   ADJUSTMENTS FOR CHANGES IN CAPITALIZATION, ETC.

          Stock appreciation rights shall be subject to adjustment by
 the Committee in its sole discretion as to the number, kind and date

 diminish in any way the right of the Corporation or any such subsidiary
 to terminate his or her employment at any time with or without cause.

          (d)  TAXES.  The Corporation shall be entitled to deduct from
 any payment under the Plan the amount of any tax required by law to be

     (i)  In the event of a Change in Control,

          (A)  all stock appreciation rights ("SARs") outstanding on the
     date on which such Change in Control has occurred (the "Change in
     Control Date") shall, to the extent not then exercisable or vested,
     immediately become exercisable in full, and

          (B)  each grantee may elect, with respect to each SAR held by
     such grantee on the Change in Control Date (the grantee's "Election
     Right"), to surrender such SAR for an immediate lump sum cash
     payment in an amount equal to the product of (1) the number of
     shares of common stock of the Company ("Shares") then subject to
     the SAR as to which the election is being exercised, multiplied by
     (2) the excess, if any, of (a) the greater of (i) the Change in
<PAGE>
     Control Price or (ii) the highest Fair Market Value of a Share on
     any day in the 60-day period ending on the Change in Control Date,
     over (b) the date of grant value of such SAR.  Upon exercise of a
     grantee's Election Right,the value of all hypothetical reinvested
     cash dividends associated with such SAR shall also be determined by
     the greater of (i) theChange in Control Price or (ii) the highest
     Fair Market Value of a Share on any day in the 60-day period ending
     on the Change in Control Date.   For purposes of this Section
     11(b), 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

                                    -14-

     11(a)(iii), the highest price per Share paid in such tender or
     exchange offer or Corporate Transaction.  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 exercise of an Election Right must be in writing,
     specify the  SAR or SARs 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.

          (iii)  All payments due an grantee pursuant to the provisions
     of this Section 11(b) shall be made by the Company on or before the
     first to occur of (A) the date provided in this Plan for payment
     upon exercise of an SAR and (B) the 5th business day following the
     date on which the grantee's election has been delivered to the
     Company pursuant to Section 11(b)(ii).

          (iv)  Notwithstanding any other provision of this Section
     11(b), if the grant or the exercise of a grantee's Election Right 
     or payment of cash provided for in this Section 11(b)would make a
     Change in Control transaction ineligible for pooling-of-interests
     accounting treatment under APB No. 16, that, but for the nature of
     such grant or exercise of Election Rights, would otherwise be
     eligible for such pooling-of-interests accounting treatment, the
     Committee shall have

                                    -15-

     the right and authority to modify, eliminate, or terminate the
     Election Right to the extent necessary to preserve such pooling-of-
     interests accounting treatment.

                                     -16-

 Orr's highest final average W-2 compensation for the five consecutive
 calendar year period in which such compensation was paid.  Mr. Orr's
 Normal Supplemental Retirement Benefit shall not be reduced or offset
 by the amount of any other payment then due him from Mosinee or any
 other plan or program now or hereafter maintained by Mosinee.

     2.   SURVIVING SPOUSE BENEFIT.  From and after the first day of the
 first month following the later of (a) the month in which Mr. Orr's

 and continuing on the first day of each succeeding month, Mosinee shall
 pay to Mr. Orr's spouse, if then living (Mr. Orr's "Surviving Spouse"),
 a monthly benefit (the "Supplemental Surviving Spouse Benefit") in an
 amount equal to 50% of the Normal Supplemental Retirement Benefit to
 which Mr. Orr would have then been entitled had he then been living.

          (a)  In the event a Change in Control of Wausau occurs prior
     to Mr. Orr's death, Mosinee shall pay to Mr. Orr a lump sum amount
     equal to the present value of Mr. Orr's Normal Supplemental
     Retirement Benefit, as determined hereunder, as of the first day of
     the first month following such Change in Control of Wausau on which
     Mr. Orr is neither an employee nor a director of Wausau, whether
     or not such Change in Control occurred prior to the date on which
     Mr. Orr shall have ceased to be an employee or a director of
     Wausau.  Upon payment of the lump sum amount provided for in this
     subparagraph (a), Mosinee shall have no further obligation to pay
     any benefits under this Plan.

          (b)  In the event a Change in Control of Wausau occurs after
     Mr. Orr's death and whether or not the Supplemental Surviving
     Spouse Benefit shall have then become payable, Mosinee shall pay to
     Mr. Orr's Surviving Spouse, if then living, the present value of
     the unpaid Supplemental Surviving Spouse Benefit. Upon payment of
     the lump sum amount provided for in this subparagraph (b), Mosinee
     shall have no further obligation to pay any benefits under this
     Plan.

                 1994 EXECUTIVE STOCK OPTION PLAN

                     As last amended effective
                           March 4, 1999

                     MOSINEE PAPER CORPORATION
                 1994 EXECUTIVE STOCK OPTION PLAN


     Mosinee Paper Corporation, a corporation with its principal place
 of business located in Mosinee, Wisconsin (the "Company"), hereby 
adopts the Mosinee Paper Corporation 1994 Executive Stock Option Plan
 (the "Plan"), as set forth herein.

     Section 1.  PURPOSE.  The Plan is intended to attract and retain
 key executive employees by permitting such employees of Mosinee Paper
 Corporation (the "Company") or any parent or subsidiary of the Company
 to acquire authorized and unissued, or reacquired, shares of common
 stock of the Company pursuant to purchase options.  The availability
 of the options and grants thereof will furnish additional inducements
 to such employees to continue employment with the Company, or any
 parent or subsidiary of the Company, and encourage them, by giving them
 an opportunity to acquire a greater stake in the Company's success, to
 increase their efforts to promote the best interests of the Company
 and its stockholders.    

     It is the express intent of the Company that, subject to Section
 6.2(g) hereof, all options granted hereunder designated "Incentive
 Stock Options" shall meet the requirements of Section 422 of the
 Internal Revenue Code of 1986, as amended (the "Code"), or any
 successor section or sections.  It is the further intent of the
 Company that options granted

                                     -1-
<PAGE>
 hereunder designated "Non-Qualified Stock Options" shall not meet the
 requirements of Section 422 of the Code.  A key employee may be granted
 and may hold one or more options under this Plan.

     Section 2.  NUMBER OF SHARES AVAILABLE FOR OPTIONS.  The aggregate
 number of shares of common stock, no par value, of the Company (the
 "Shares") which may be issued under options granted pursuant to the
 Plan shall be 100,000.

     Section 3.  ADMINISTRATION OF THE PLAN.

     Section 3.1  GENERAL.  The Plan shall be administered by a
 committee (the "Committee") consisting of at least two members
 designated by the Board of Directors of the Company from among those
 of its members who are not officers or employees of the Company or a
 parent or subsidiary of the Company and who otherwise satisfy the
 definition of a "Non-Employee Director" in Rule 16b-3(b)(3) promulgated
 under Section 16 of the Securities Exchange Act of 1934 (the "Exchange
 Act").  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.

     Section 3.2  AUTHORITY OF COMMITTEE.  The Committee shall have full
 and complete authority to grant options to such eligible employees on

                                     -2-

 such terms, which need not be the same as to all Optionees, as will, in
 its discretion and subject only to the specific limitations elsewhere
 contained in the Plan, carry out the purpose of the Plan.  The
 Committee shall also have full and complete authority to interpret the
 Plan and adopt rules governing the administration of the Plan.  The
 Committee's decision on any matter with respect to the Plan shall be
 final.

     Section 3.3  INDEMNIFICATION OF COMMITTEE.  To the extent permitted
 by applicable law, the members of the Committee and each of them shall
 be indemnified and saved harmless by the Company from any liability or
 claim of liability which may arise from the administration of the Plan
 if the acts giving rise to such liability or claim of liability were
 taken in good faith and without negligence.

     Section 4.  ELIGIBLE EMPLOYEES.

     Section 4.1  DEFINITION OF ELIGIBLE EMPLOYEES.  Subject to the
 limitations of Section 4.2, key employees (who may also be officers or
 directors) of the Company (or any parent or subsidiary of the Company)
 shall be eligible to participate in the Plan.  For purposes of the
 Plan, the term "key employee" shall include all employees of all
 participating employers employed in management, administrative or
 professional capacities.

                                    -3-

     Section 4.2  LIMITATIONS ON ELIGIBILITY.  Directors of the Company
<PAGE>
 (or its parent or subsidiary) who are not also employees of such entity
 shall not be eligible to receive options under the Plan.  No person who
 is serving as a member of the Committee shall be eligible to receive an
 option; provided, however, that options outstanding prior to an
 Optionee's becoming a member of the Committee shall remain in effect.

     Section 5.  GRANTING OF OPTIONS.  Subject to the limitations of
 Section 4.2, options to purchase Shares shall be granted to such key
 employees who are eligible to participate in the Plan as the Committee
 may, from time to time and at any time, select.  Membership in a class
 of eligible key employees shall not, without specific Committee action,
 entitle a key employee to receive an option to purchase Shares.
 Eligible key employees selected by the Committee shall be referred to
 herein as "Optionees."  Options to purchase Shares which are granted
 prior to the approval of the Plan by the Company's stockholders shall
 be expressly conditioned upon such approval.

     Section 6.  TERMS AND CONDITIONS OF THE OPTIONS.

     Section 6.1  WRITTEN INSTRUMENT.  Each option to purchase Shares
 granted under the Plan shall be evidenced by a written option agreement
 signed on behalf of the Company and the Optionee which sets forth the
 name of the Optionee, the date granted, the price at which the Shares

                                    -4-

 subject to the option may be purchased (the "option price"), whether
 the option is an Incentive Stock Option or a Non-Qualified Stock
 Option, the number of Shares subject to the option and such other terms
 and conditions consistent with the Plan as determined by the Committee.
 The Committee may at the time of grant or at any time thereafter impose
 such additional terms and conditions on the exercise of such option as
 it deems necessary or desirable for compliance with Section 16 of the
 Exchange Act and the regulations promulgated thereunder.  Such option
 agreement shall incorporate by reference all terms, conditions and
 limitations set forth in the Plan.

     Section 6.2  TERMS AND CONDITIONS OF THE OPTIONS.  In addition to
 any other limitations, terms and conditions specified in the Plan, each
 option granted hereunder shall, as to each Optionee, satisfy the
 following requirements:

     (a)  DATE OF GRANT.  Options must be granted on or before October
 19, 2004.

     (b)  EXPIRATION.  No Incentive Stock Option shall be exercisable
 after the expiration of ten years from the date such option is granted.
 No Non-Qualified Stock Option shall be exercisable after the expiration
 of twenty years from the date such option is granted.

     (c)  PRICE.  The option price as to any Share subject to either an
 Incentive Stock Option or Non-Qualified Stock Option will be not less

                                     -5-
<PAGE>
 than one hundred percent of the fair market value of the Share on the
 date the option is granted.  For purposes of the Plan, the fair market
 value of a Share means:

     (i)  The mean between the high and the low prices at which the
          Shares were traded if the Shares were then listed for trading
          on a national or regional securities exchange or were then
          traded on a bona fide over-the-counter market; or

     (ii) If the Shares were not traded on an exchange or a bona fide
          over-the-counter market, a value determined by an appraiser
          selected by the Committee.

 In the event that the date on which the fair market value of a Share is
 to be determined is a date on which there is no trading of the Shares
 on a national or regional securities exchange or on the
 over-the-counter market, such fair market value shall be determined by
 referring to the next preceding business day on which trading occurs.

     (d)  TRANSFERABILITY.

     (i)  No Incentive Stock Option shall be transferable by the
          Optionee otherwise 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.

     (ii) The Committee may, in its discretion, authorize all or a
          portion of any options to be granted to an Optionee or which
          were granted to any Optionee on or before October 31, 1996 to
          
                                     -6-

          permit transfer by the Optionee to (A) the spouse, children or
          grandchildren of the Optionee ("Immediate Family"), (B) a
          trust for the exclusive benefit of the Optionee or the
          Optionee's Immediate Family, (C) a partnership in which the
          Optionee or the Optionee's Immediate Family are the only
          partners, or (D) to a former spouse of the Optionee pursuant
          to a domestic relations order within the meaning of Rule
          16a-12 promulgated under Section 16 of the Exchange Act;
          provided, however, that (X) there may be not consideration for
          any such transfer, (Y) the written option agreement required
          by Section 6.1, or any amendment thereof approved by the
          Committee, must expressly provide for transferability of the
          option evidenced in such agreement in a manner consistent with
          this Section 6.2(d), and (Z) once transferred pursuant to the
          preceding provisions of the Section 6.2(d)(ii), no subsequent
          transfer of any options shall be permitted except a transfer
          by will or the laws of descent and distribution.  In
          authorizing all or any portion of an option to be transferred,
          the Committee may impose any conditions on exercise, prescribe
          a holding period for the Shares acquired upon such exercise
          and/or impose any other conditions or limitations it deems
          desirable or necessary in order to carry out the purposes and
          requirements of the Plan.  Following transfer, the

                                    -7-
<PAGE>
          terms and conditions of the plan and the written option
          agreement relating to such option shall continue to be
          applicable in all respects to the Optionee making such
          transfer and each transferred option shall continue to be
          subject to the same terms and conditions as were applicable
          immediately prior to transfer as if such option had not been
          transferred, including, but not limited to, the terms and
          conditions with respect to the lapse and termination of such
          option.  For purposes of Section 7, the transferee of an
          option shall be deemed an "Optionee".  Neither the Company,
          the Committee or any Optionee shall have any obligation to
          inform any transferee of the termination or lapse of any
          option for any reason.  Notwithstanding any other provision of
          the plan, (YY) following the termination of employment of an
          Optionee, a transferred Non-Qualified Option shall be
          exercisable by the transferee only to the extent, and
          for the periods specified in Section 6(e) as if such option
          had not been transferred and (ZZ) no Non-Qualified Stock
          Option granted prior to October 31, 1996 may be transferred
          until such option has been held by the Optionee for a period
          of not less than six months after the date on which such
          option was granted.

     (e)  EMPLOYMENT.  Except as otherwise provided in the next
          sentence, no option shall be exercisable unless the Optionee
          shall have been employed by the Company (or any present or
          future parent or subsidiary of

                                     -8-

 the Company) during the period beginning on the date the option is
 granted and ending on a date ninety days before the date of exercise
 (and subject to Section 10 herein); provided, however, that in the
 event an Optionee dies while in the employ of the Company (or any
 present or future parent or subsidiary of the Company) or within ninety
 days after such employment had terminated, the employment period
 requirement described above shall be deemed to have been satisfied.  In
 the event an Optionee has attained his Retirement Date (as defined
 herein), (i) the provisions of the preceding sentence shall not be
 applicable to such Optionee's Non-Qualified Stock Options and (ii) such
 Optionee's Non-Qualified Stock Options shall not be exercisable after
 the second anniversary of such Optionee's Retirement Date.  For
 purposes of this Plan, the term "Retirement Date" shall mean the date
 on which the Optionee's employment with the Company (and any parent or
 subsidiary of the Company) terminates (including termination because of
 death) if the Optionee had then attained age 55 and completed ten
 calendar years of service with the Company (or any parent or subsidiary
 of the Company).

     (f)  MINIMUM HOLDING PERIOD.  No option granted prior to November
 1, 1996 may be exercised before the date which is six months after the
 date on which such option was granted.  Each option shall contain such
 additional or other restriction or restrictions with respect to the
 stated percentage of Shares covered by such option as to which such
 option may be

                                     -9-
<PAGE>
 exercised as the Committee may deem desirable or necessary in order to
 carry out the purposes and requirements of the Plan.

     (g)  LIMITATION ON OPTION GRANTS.  No Optionee may be granted
 options in any calendar year with respect to more than 50,000 shares.

     (h)  ADDITIONAL RESTRICTIONS RELATING TO INCENTIVE STOCK OPTIONS.
 To the extent that the aggregate fair market value (determined as of
 the time the option is granted) of the Shares for which Incentive Stock
 Options are exercisable for the first time by an individual during any
 calendar year (under this Plan or any other plan of the Company or any
 of its subsidiaries) exceeds $100,000 (or such other individual limit
 as may be in effect under the Code on the date of grant), such options
 shall not be Incentive Stock Options.  No Incentive Stock Option shall
 be granted to an employee who, at the time such option is granted, owns
 stock possessing more than ten percent of the total combined voting
 power of all classes of stock of the Company or any parent or
 subsidiary of the Company within the meaning of Section 422(b)(6) of
 the Code unless: (i) at the time the option is granted, the option
 price is at least one hundred ten percent 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 granted.

     Section 7.  EXERCISE AND PAYMENT OF OPTION PRICE.

                                   -10-

     Section 7.1  EXERCISE OF OPTIONS.  Options shall be exercised as to
 all or a portion of the Shares by delivery of an irrevocable 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 minimum required tax withholding).
 The date of exercise shall be the date such written notice and payment
 have been 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.  No option may be exercised with respect to a fractional share
 of stock.  Notwithstanding the fact that an option has been transferred
 pursuant to Section 6.2(d)(ii), the grantee of such option shall remain
 liable for any required tax withholding.

     Section 7.2  PAYMENT FOR SHARES.  Payment of the option price (plus
 minimum required tax withholding) may be made by (a) tendering cash (in
 the form of a check or otherwise) in such amount, or (b) with the
 consent of the Committee, tendering Shares with a fair market value on
 the date of exercise equal to such amount, or (c) 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.  Notwithstanding the fact that an option has been
 transferred pursuant to Section 6.2(d)(ii), the grantee of such option
 shall remain liable for any required tax withholding.

                                    -11-
<PAGE>
     Section 8.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION.  If the
 Company shall, after the Effective Date, change its common stock into a
 greater or lesser number of shares through a stock dividend, stock
 split-up or combination of shares, then

     (i)  the number of Shares then subject to the plan but which are 
          not then subject to any outstanding option;

     (ii) the number of Shares subject to each then outstanding option
          (to the extent not previously exercised); and

     (iii) 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.  If any split-up or combination
 of shares shall involve a change of par value, the Shares subject to
 options theretofore or thereafter granted shall be the Shares as so
 changed.

     If, after the Effective Date, there shall be any change in the
 stock of the Company other than through a stock dividend, stock
 split-up or combination of shares, or other change listed in Section 9
 herein, then if (and only if) the Committee shall determine that such
 change equitably requires an adjustment in the number or kind or option
 price of Shares then subject to an option, or the number or kind of
 Shares remaining subject to the Plan, such adjustment as the Committee
 shall determine is

                                     -12-

 equitable and as shall be approved by the Board shall be made and shall
 be effective and binding for all purposes of such option and the Plan.
 If any member of the Board shall, at the time of such approval, be an
 Optionee, he shall not participate in action in connection with such
 adjustment.

     Section 9.  MERGER, REORGANIZATION, OR CHANGE IN CONTROL.
     (a)  Nothing contained in this Plan or in any option granted under
 the Plan shall in any way prohibit the Company from merging with or
 consolidating into another corporation, or from selling or transferring
 all or substantially all of its assets, or from distributing all or
 substantially all of its assets to its stockholders in liquidation, or
 from dissolving and terminating its corporate existence; and in any
 such event (other than a merger in which the Company is the surviving
 corporation and after which the Company remains an independent,
 publicly held corporation), the Company or any surviving party to any
 such merger, consolidation, or sale or transfer of assets may provide
 by resolution of its Board of Directors that all rights of the person
 or persons entitled to exercise then outstanding options granted under
 the Plan, and such options, shall wholly and completely terminate at
 the time of any such merger, consolidation, sale or transfer of assets,
 liquidation, or dissolution, except that adequate provision for such
 person or persons shall be made in accordance with paragraph (b) below.
<PAGE>
     (b)  In the event that (i) any individual, corporation, partnership
 or other person or group of persons or entities becomes the beneficial

 of Shares subject to such option.  Such payment shall be made in cash
 within 30 days after, in the case of a Reorganization requiring

 employment had terminated, an option may be exercised, to the extent
 exercisable by the Optionee immediately prior to his death, in whole or
 in part by the Optionee's estate or designee by will, or, if

     Section 11.  AMENDMENT AND TERMINATION OF PLAN.

     Section 11.1  AMENDMENT OF PLAN.  The Board of Directors of the
 Company may amend the Plan from time to time and at any time; provided,
 however, that no amendment shall adversely affect any option which has
 been granted prior to the amendment and no amendment with respect to
 the maximum number of Shares which may be issued pursuant to options or
 the class of eligible employees, or which materially increases benefits
 accruing to Optionees under the Plan (within the meaning of section
 162(m) of the Code) shall be effective unless approved by a majority of
 the shares entitled to vote at a meeting of shareholders.

     Section 11.2  TERMINATION OF PLAN.  The Plan shall terminate on the

 option.  Each participating employee and assignee in interest of the
 employee accordingly represents, as a condition of participation in the
 Plan, that Shares which are unregistered under the Act are being

 investment only and not with a view to offer for sale or for sale in
 connection with the distribution or transfer thereof.

     Section 14.  AVAILABILITY OF INFORMATION.  The Company shall
 furnish each Optionee with (a) a copy of the Plan and the Company's
 most recent annual report to its shareholders at the time the option

 on Form 10-K, its quarterly reports on Form 10-Q, and its proxy
 statements.

     Section 15.  CONDITIONS OF EMPLOYMENT.  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 parent or subsidiary of the Company and the Company
 and its participating subsidiaries hereby expressly reserve the right
 to terminate the employment of any employee, with or without cause,
 regardless of the Plan and any options granted pursuant to it.

     Section 16.  MISCELLANEOUS.

     (a)  The transfer of an employee from the Company to a parent or
 subsidiary of the Company or from a parent or subsidiary of the Company
 to the Company or another parent or subsidiary of the Company shall not
 be a termination of employment or an interruption of continuous
 employment for the purpose of the Plan.

     (b)  As used in the Plan, the term "parent" and "subsidiary" shall
 have the meanings ascribed to them in Sections 421, 422A and 425 of the
 Code.

 shall be advised by its counsel that the exercise of any option or the

                                     -18-

 delivery of shares of Stock upon the exercise of an option is required
 to be approved, registered or qualified under any applicable law, or
 must be accompanied or preceded by a prospectus or similar circular
 meeting the requirements of any applicable law, the Company will use
 reasonable efforts to obtain such approval, to effect such
 registrations and qualifications, or to provide such prospectus or
 similar circular within a reasonable time, but exercise of the options
 or delivery by the Company of certificates for shares of Stock may be
 deferred until such approvals, registrations or qualifications are
 effected, or until such prospectus or similar circular is available.

     Section 18.  Notwithstanding any other provision of this Plan or of
 any option agreement relating to any option granted hereunder, the
 consummation of the transactions contemplated by that certain Agreement
 and Plan of Merger, dated as of August 24, 1997, by and among Wausau
 Paper Mills Company, WPM Holdings, Inc. and the Company on
 substantially the terms and conditions set forth therein as of August
 24, 1997 shall not be deemed to constitute a "Change in Control" or any
 other transaction described in Section 11(b) of this Plan and of any
 corresponding or similar provision of any such option agreement.  
 Without limiting the generality of the foregoing, the consummation of
 such transactions shall not result in the payment of any cash to any
 holder of an option granted under this Plan.

 promulgated under the Exchange Act) of 20% or more of either (i) the

 directly from the Corporation other than an acquisition by

                                     -20-

 virtue of the exercise of a conversion privilege unless the security
 being so converted was itself acquired directly from the Corporation,

 employee benefit plan (or related trust) sponsored or maintained by
 the Corporation or any entity controlled by the Corporation, (D) any

 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

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

 (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

 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

                                     -23-

     Section 9.2  EFFECTS OF CHANGE IN CONTROL.

     (a)  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") shall, to
          the extent not then exercisable or vested, immediately become
          exercisable in full, and

                                     -26-

     (ii) each Optionee may elect, with respect to each option held by
          such Optionee on the Change in Control Date (the Optionee's
         "Election Right"), to surrender such option for an immediate
          lump sum cash payment in an amount equal to the product of (A)
          the number of shares of common stock of the Corporation (for
          purposes of this Section 9.2, "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 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 9.2, 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 9.1(c), the highest price
          per Share paid in such tender or exchange offer or Corporate
          Transaction; provided, however, that in the case of Incentive
          Stock Options, the Change in Control Price shall be in all
          cases the fair market value of the Shares on the date such
          Incentive Stock Option is exercised.  To the extent that the
          consideration paid in any such transaction consists all or in
          part of securities or other noncash consideration, the value

                                    -27-

          of such securities or other noncash consideration shall be
          determined in the sole discretion of the Committee.

     (b)  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 Corporation 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 Corporation's home office
          on or before the 60th day following the Change in Control
          Date.
<PAGE>
     (c)  All payments due an Optionee pursuant to the provisions of
          this Section 9.2 shall be made by the Corporation on or before
          the 5th business day following the date on which the
          Optionee's election has been delivered to the Corporation
          pursuant to Section 9.2(b).

     (d)  Notwithstanding any other provision of this Section 9.2, if
          the grant or the exercise of an Optionee's Election Right or
          payment of cash provided for in Section 9.2(b) would make a
          Change in Control transaction ineligible for
          pooling-of-interests accounting treatment under APB No. 16,
          that, but for the nature of such grant or exercise of Election
          Rights or payment of cash, would otherwise be eligible for
          such pooling-of-interests accounting treatment, the Committee
          shall have the right and authority to

                                    -28-

         substitute for the cash payments to be made to the Optionee
         pursuant to Section 9.2(a), Shares with a fair market value,
         determined as of the date of delivery of such Shares, equal to
         the cash that would otherwise be payable to such Optionee in
         connection with the exercise of an Optionee's Election Right
         hereunder or, to the extent necessary to preserve such
         pooling-of-interests accounting treatment, to otherwise modify,
         eliminate, or terminate such Election Right.

                                     -29-

                 WAUSAU-MOSINEE PAPER CORPORATION
                   INCENTIVE COMPENSATION PLANS
                                FOR
                        EXECUTIVE OFFICERS
                              (1999)


     The President and CEO's bonus opportunity for 1999 ranges from 0%
 of base salary if 1999 earnings per share are at or below $.94 to 100%
 if the 1999 earnings per share are at least $1.40 per share.

     The Senior Vice President, Finance, Senior Vice President,
 Administration, and Senior Vice President, Engineering and
 Environmental Services each have a bonus opportunity equal to 75% of
 their base salary based upon the same $.94 to $1.40 range of earnings
 per share and will also be entitled to a maximum bonus of 25% of base
 salary upon satisfaction of individual performance objectives
 established at the beginning of the year by the President and CEO.
<PAGE>
     Each Senior Vice President charged with the management of an
 operating group will participate in an incentive compensation plan
 under which 75% of his bonus will be based on the operating profits of
 his group and 25% on satisfaction of individual performance objectives
 established at the beginning of the year by the President and CEO.  In
 each case, achievement of the minimum targeted operating profit will
 pay 20% of base salary with a pro rata increase of up to 100% of base
 salary based upon achievement of operating profit goals.

     Earnings per share will be adjusted for accruals on SARs, bonus
 expense and extraordinary items.  Outstanding shares used to calculate
 the range were 52,482,000 shares.  If the actual average shares
 outstanding for 1999 is more or less, actual earnings per share
 will be adjusted to 52,482,000 shares with a corresponding plus or
 minus to interest expense for the actual effect of debt used to
 repurchase stock as compared to the plan, which assumed even purchases
 throughout the year.
