 Item 1.  BUSINESS.

 NATURE OF THE BUSINESS

 The company, incorporated in 1899 under the laws of the State of
 Wisconsin, manufactures and sells paper.  The company is organized into a
 small corporate staff consisting of principal executive officers and two
 operating divisions: the Printing and Writing Division, consisting of a
 paper and pulp mill in Brokaw, Wisconsin and Wausau Papers of New
 Hampshire, Inc., a wholly-owned subsidiary which operates a paper mill in
 Groveton, New Hampshire; and the Technical Specialty Division, which
 consists of Rhinelander Paper Company, Inc., a wholly-owned subsidiary
 operating a paper mill in Rhinelander, Wisconsin, and Wausau Papers Otis
 Mill, Inc., a wholly-owned subsidiary which operates a paper mill in Jay,
 Maine.  Unless stated otherwise, the terms "company" and "Wausau Papers"
 mean Wausau Paper Mills Company.  The company's executive offices are
 located in Wausau, Wisconsin.

 The company's export sales are administered through Wausau Papers
 International, Inc., a wholly-owned subsidiary which acts as a foreign
 sales corporation (FSC).

 On August 24, 1997, Wausau Paper Mills Company, Mosinee Paper Corporation
 ("Mosinee") and WPM Holdings, Inc., a wholly-owned subsidiary of the
 company ("Merger Sub"),  entered into an Agreement and Plan of Merger
 (the "Merger Agreement") pursuant to which Merger Sub will be merged
 with and into Mosinee (the "Merger") with Mosinee being the surviving
 corporation.  Under the terms of the Merger Agreement, which was
 unanimously approved by the Boards of Directors of the company and
 Mosinee, each outstanding share of Mosinee common stock will be converted
 into the right to receive 1.4 shares of Wausau common stock, with cash
 paid in lieu of fractional shares.  The Merger, which is subject to
 approval by the shareholders of both the company and Mosinee, regulatory
 approval and other customary conditions, will be accounted for as a
 pooling of interests and is expected to close by the end of calendar
 1997.

 Mosinee manufactures, converts and sells paper products.  Mosinee, one of
 the nation's largest producers of masking tape base, manufactures a broad
 range of highly engineered paper products.  These include high-performance
 industrial papers chemically treated for wet strength, flame retardancy,
 anti-static, corrosion or grease resistance for various industries, such
 as automotive, housing, and food processing, as well as other specialty
 grades of paper, including decorative laminate papers, deep color tissue
 used in napkin and tablecloth stock and colored school construction paper.
 Other major products and processes include wax-laminate roll wrap, custom
 coating, laminating and converting.  In addition, Mosinee produces
 "away-from-home" towel and tissue products from recycled material under
 Bay West's EcoSoft(tm) brand which are used in the washrooms of theme
 parks, hospitals, hotels, office buildings, factories, schools and
 restaurants nationwide.  Mosinee had revenues of $314.5 million and net
 income of $26.9 million in 1996 and revenues of $163.5 million and net
 income of $16.2 million for the six months ended June 30, 1997.
<PAGE>
 This report on Form 10-K does not reflect any effect the proposed merger
 with Mosinee may have on the company.

 SEGMENT INFORMATION

 Paper manufacturing is the company's only line of business.

 PRINTING AND WRITING DIVISION

 The Printing and Writing Division manufactures fine printing, writing and
 specialty papers at the Brokaw, Wisconsin and Groveton, New Hampshire
 mills.  The division's product lines include recycled products made with
 20% of the total fiber content from post-consumer waste.  The printing and
 writing papers are sold to paper distributors and converters throughout
 the United States, Canada and Mexico.  Typical end uses for these fine
 papers include printed advertising, corporate external reports, office
 papers and converted products such as announcements and greeting card
 envelopes.

 The Printing and Writing Division was formed in 1993 by combining the
 operations of the company's Brokaw Division and the manufacturing facility
 at Groveton, New Hampshire.  The Groveton facility was purchased in April
 1993, by the company's wholly-owned subsidiary Wausau Papers of New
 Hampshire, Inc.

 TECHNICAL SPECIALTY DIVISION

 The Technical Specialty Division manufactures lightweight, dense,
 technical specialty papers, which are primarily sold directly to
 converters and end users throughout the United States.  International
 markets for the division's products include Canada, the Pacific Rim,
 Europe, Mexico and Central and South America.  Typical end uses for these
 papers are pressure sensitive products, silicone coated products, medical
 packaging, food packaging, multiple laminated products, electrographics
 and imaging papers.  Small volumes of yeast and lignosulfonates are also
 manufactured.  These products are sold for use as food additives, pet food
 ingredients and for other end uses.

 The Technical Specialty Division was created in 1997 by combining the
 operations of the company's Rhinelander Division and the company's mill at
 Jay, Maine (the "Otis mill").  The assets and business of the Otis mill
 were acquired on May 12, 1997 by the company's newly formed wholly-owned
 subsidiary, Wausau Papers Otis Mill, Inc.  This purchase expanded the
 company's technical specialty manufacturing capacity by 70,000 tons per
 year.

 EXPORT SALES

 Wausau Papers International, Inc. has been the commissioned sales agent
 for the export sales of the company since September 1, 1992.  Wausau
 Papers International, Inc. has elected to be treated as a FSC for federal
 income tax purposes.

 On June 9, 1997, the company opened a regional sales office in Singapore.
 The Singapore office is used to service existing business in the Far East,
 as well as to pursue new business opportunities and relationships for both
 the Technical Specialty and Printing and Writing divisions.
<PAGE>
 RAW MATERIALS

 Pulp is the basic raw material for paper production.  Approximately 60% of
 the pulp consumed by the Brokaw mill is manufactured internally from
 aspen, which is in abundant supply.  The

                                   -2-

 remaining 40% of required pulp at Brokaw and all of the required pulp at
 the Rhinelander, Groveton and Otis mills is purchased from pulp mills
 throughout the United States and Canada. Market pulp is in adequate
 supply and readily obtained from both domestic and foreign sources.  The
 company may purchase small quantities of its pulp using futures contracts
 as a hedge against anticipated pulp price increases.

 Recycled, de-inked fiber with a high content of post-consumer waste is
 purchased from domestic suppliers as part of the fiber requirements for
 the Printing and Writing Division's recycled products.  Recycled fiber is
 also in adequate supply and readily obtained.

 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.

 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 Brokaw mill operates a power plant which
 provides all of its steam requirements.  The power plant is fueled by
 natural gas, which is in adequate supply, with fuel oil as an alternate
 energy source.  The Brokaw mill purchases 100% of its electrical
 requirements from a public utility company.  The Groveton and Otis mills
 operate power plants which provide 100% of the mills' steam requirements
 and a portion of their electrical needs. The power plants at both the
 Groveton and Otis mills operate on fuel oil which is in adequate supply.
 The Rhinelander mill maintains a power plant, fueled by coal and natural
 gas, capable of generating the mill's steam needs and nearly half of its
 electrical needs.  The Rhinelander, Groveton and Otis mills purchase
 approximately 65%, 70% and 91% of their electrical needs, respectively,
 from public utility companies.  The company generally purchases natural
 gas and fuel oil on a contract basis at prevailing market prices. 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 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 will construct necessary gas
 supply and delivery equipment to the company's Groveton, New Hampshire
 mill thereby assuring natural gas delivery at market rates.  The Groveton
 mill will be responsible for specified delivery charges under the terms of
 the contract. The company is progressing on schedule to begin
 transportation of natural gas to the Groveton mill in fiscal 1999. Capital
 improvements to the Groveton mill's power plant will be required to take
 advantage of this agreement.  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.
 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 second fiscal quarter, in

                                   -3-

 comparison to the rest of the year, primarily due to downtime typically
 taken by its converting customers during the holiday season and a general
 slowing of business activity 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

 Avery Dennison Corporation and ResourceNet International, a division of
 International Paper Company, accounted for 13.9% and 10.9% of consolidated
 net sales, respectively, in fiscal 1997.  The loss of either customer
 would have an initial material adverse effect on the company; however, the
 company believes that, in the long-term, satisfactory alternative
 marketing arrangements could be made.

 BACKLOG

 The company's order backlog at August 31, 1997 amounted to $32,969,000, or
 over 2 weeks of operation.  This is 29% higher on a tonnage basis than the
 backlog of orders of $26,749,000 or just over 2 weeks of operation at
 August 31, 1996.  The backlog increase is due primarily to additional
 volume associated with the addition of the Otis mill.

 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
 August 31, 1997 is expected to be shipped during fiscal 1998.

 COMPETITIVE CONDITIONS

 The company competes in different markets within the paper industry.  Each
 of its two divisions serves distinct market niches.  The Printing and
 Writing Division produces fine printing and writing papers, of which over
 60% are colored papers.  Fine printing and writing sales are estimated to
 be less than 3% of the total market.  The division's competitors range
 from small to large paper manufacturers and represent many different
 product lines.  The division distributes its products primarily through
<PAGE>
 paper wholesalers.  The Technical Specialty Division produces technical
 specialty papers and is a leader in its markets.  Market position varies
 by product segment and, thus, competition also includes small to large
 paper manufacturers.  The Technical Specialty Division sells most of its
 products directly to converters and end users.  The various markets for
 the products of the company are highly competitive, with competition based
 on service, quality and price.

 RESEARCH AND DEVELOPMENT

 Expenditures for product development were approximately $1,503,000 in
 1997, $1,381,000 in 1996 and $1,219,000 in 1995.

                                   -4-

 ENVIRONMENT
 Wausau Papers 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, the $14 million rebuild
 and expansion of the wastewater treatment plant at the Brokaw mill was
 completed in fiscal 1997.  The company estimates that its capital
 expenditures for environmental purposes will be less than $2 million in
 fiscal 1998.

 The company has not been identified as a potentially responsible party at
 any site designated for remedial action under the federal Superfund law.
 The company is required to monitor conditions relative to its past waste
 disposal activities and may be required to take remedial action if
 conditions are discovered which warrant such action.

 The United States Environmental Protection Agency (EPA) has published
 draft rules under the Clean Water Act and the Clean Air Act which would
 impose new air and water quality standards for pulp and paper mills (the
 "Cluster Rules").  The definitive Cluster Rules, when finally promulgated,
 are expected to require compliance within three years after the date of
 adoption.  Final promulgation of the rules for "paper grade sulfite" mills
 (which would include the Brokaw mill) is currently projected for late
 1997.  One major aspect of the proposed new regulations may require the
 company to adopt Total Chlorine Free (TCF) technology for the pulp
 bleaching operations at the Brokaw mill.  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.  Based on the company's preliminary
 estimates, if the Cluster Rules were adopted in substantially their
 present form, compliance with a TCF requirement for the Brokaw mill would
 require a capital expenditure of $3 to $5 million.  The company believes
 that the costs for compliance with the proposed Cluster Rules and other
 environmental regulations will not have a material adverse effect on its
 liquidity, operations or consolidated financial condition.

 EMPLOYEES

 The company had 2,071 employees at August 31, 1997.  The company has
 collective bargaining contracts with the United Paperworkers International
 Union and the National Conference of Firemen and Oiler Service Employees
 International Union covering approximately 1,617 employees.  These
 contracts expire in May 2000, December 2000, May 2001 and March 2002 at
 the Otis, Rhinelander, Brokaw and Groveton mills, respectively.  The
 company considers its relationship with its employees to be excellent.

 CAUTIONARY STATEMENT

 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").  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 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.  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:

 <bullet>  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.

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

 <bullet>  Changes in the price of pulp, the company's main raw material.
           Approximately 80% of the company's pulp needs are purchased on
           the open market and price changes for pulp have a significant
           impact on the company's costs.  Pulp price changes can occur
           due to worldwide consumption levels of pulp, pulp capacity
           additions, expansions or curtailments affecting 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.

 <bullet>  Unforeseen operational problems at any of the company's
           facilities causing significant lost production and/or
           cost issues.

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

 <bullet>  Changes in laws or regulations which affect the company.

                                   -7-

 Item 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
 RESULTS OF OPERATIONS.

 RESULTS OF OPERATIONS

      OVERVIEW

 Wausau Papers posted record shipments, sales and earnings in fiscal 1997.
 The company set new production records and maintained full operations
 during a year of less than robust market conditions. Selling prices for
 the company's paper products came under pressure in fiscal 1997 due to
 competitive market conditions, resulting in lower average paper prices
 compared to the previous year.  Despite downward pressure on selling
 prices, the company's overall margin improved as a result of lower pulp
 costs, mix enhancement, productivity gains from its paper mill operations
 and continued focus on cost reduction.

 Pulp prices remained relatively stable throughout most of fiscal 1997.
 This was a marked contrast to the major pulp cost swings experienced in
 recent years. In the fourth quarter of fiscal 1997, pulp prices did rise
 slightly due to increased demand for pulp. An additional price increase
 has been announced by some suppliers for November 1997, although it is
 uncertain whether there is sufficient strength in the pulp market to
 support an increase at this time.

 Fiscal 1997 was also a year of significant events for Wausau Papers. On
 May 12th, the company acquired the business and assets of Otis Specialty
 Papers, located in Jay, Maine, from Rexam Inc. for $55.1 million. Wausau
 Papers has combined the operations of its Rhinelander and Otis mills to
 create its newly formed Technical Specialty Division. The purchase
 included two paper machines producing high quality supercalendered kraft
 release paper, thermal paper and other technical specialty papers. This
 acquisition expanded the company's technical specialty capacity by 70,000
 tons per year. Another major event occurred on August 25th when the
 company, in a joint news release with Mosinee Paper Corporation, announced
 plans to merge the two companies in an all-stock transaction. (For further
 information regarding the proposed merger refer to Item 1.)  The merged
 companies, to be called Wausau-Mosinee Paper Corporation, will create an
 even stronger specialty paper producer, with combined revenues of
 approximately $1 billion and a strong balance sheet from which to pursue
 growth internally and through complementary niche acquisitions.  Subject
 to the terms of the merger agreement, the company expects the merger will
 be completed before the end of calendar year 1997.

 Management's discussion and analysis of financial condition and results of
 operations does not reflect any effect on the company's operations or its
 capital resources and liquidity which may result from the proposed merger
 with Mosinee Paper Corporation.

      NET SALES

 Fiscal 1997 net sales were a record $570.2 million, 5% higher than fiscal
 1996 net sales of $542.7 million. Net sales were $515.7 million in fiscal
 1995. Shipments were also at a record level 459,700 tons in fiscal 1997,
 an increase of 12% from 409,700 tons shipped a year ago. Fiscal 1995
 shipments were 399,300 tons. Fiscal 1997 net sales and shipments include
 nearly four months of contribution from the May 12, 1997 acquisition of
 Otis Specialty Papers.
<PAGE>
 At the company's Technical Specialty Division, shipments increased 26% in
 fiscal 1997, with the Rhinelander mill realizing 10% growth in its
 shipments compared to a year ago. Shipments of the company's pressure
 sensitive products were strong despite very competitive market conditions,

                                  -10-

 increasing 24% at the Rhinelander mill and 42% division-wide. Fiscal 1997
 average paper prices at the Technical Specialty Division were lower than a
 year ago, on average, as a result of competitive pressures from both
 domestic and foreign paper producers. The Technical Specialty Division has
 experienced some market softening in early fiscal 1998, however, continued
 growth in its pressure sensitive grades is expected in fiscal 1998.

 At the company's Printing and Writing Division, shipments increased 5%,
 compared to fiscal 1996 results. Healthy increases in the division's
 premium paper sales were realized in fiscal 1997, while reducing its mix
 of lower priced commodity grades. Mix enhancement will continue to be a
 major focus in fiscal 1998.  Despite the mix improvement, downward
 pressure on paper prices, as a result of soft market conditions in fiscal
 1997, resulted in significantly lower average prices for the company's
 printing and writing grades, compared to a year ago.

 Order backlog at the end of fiscal 1997 was $33.0 million, compared to
 order backlogs of $26.7 million and $25.0 million at August 31, 1996 and
 1995, respectively. Order backlog at August 31, 1997, on a tonnage basis,
 was 29% higher than a year ago and 55% better than at the end of fiscal
 1995. The increase in the company's order backlog at the end of fiscal
 1997, compared to the prior year, is due primarily to the additional
 volume from the Otis mill which was not in last year's backlog. The
 company believes backlog totals do not indicate correctly the entire
 strength of its business, given that a high percentage of orders are
 shipped out of inventory promptly upon order receipt.

 In the fourth quarter of fiscal 1997, the company opened a regional sales
 office in Singapore.  The Singapore office is used to service existing
 business in the Far East, as well as to pursue new business opportunities
 for the company's Printing and Writing and Technical Specialty divisions.

      GROSS PROFIT

 Gross profit increased to $114.0 million or 20.0% of net sales in fiscal
 1997, compared to a fiscal 1996 gross profit of $99.3 million or 18.3% of
 net sales. Fiscal 1995 gross profit was $80.7 million or 15.7% of net
 sales. Gross profit margin improved in fiscal 1997 primarily as a result
 of higher sales volume, lower pulp costs, improved mix, productivity gains
 from paper mill operations and cost reduction efforts including
 improvements generated from the Total Quality Improvement Process.

 Market prices for pulp, the company's primary raw material used in
 manufacturing paper, were relatively stable throughout most of fiscal
 1997. In fiscal 1997, the average list price of northern bleached softwood
 kraft, a frequently used benchmark pulp grade, decreased 18% from the
 fiscal 1996 average, compared to an 8% decrease in fiscal 1996 and a 55%
 increase in fiscal 1995. Pulp prices did increase slightly at the end of
 fiscal 1997 and an additional price increase has been announced by some
 suppliers for November 1997. Paper industry publications have expressed
 some doubt, however, as to whether there is sufficient strength in the
 pulp market to support the November price increase.
<PAGE>
 The company's paper mills at its Printing and Writing Division operated at
 capacity in fiscal 1997. Paper production increased 5% over fiscal 1996
 results due to productivity gains from capital and operational
 improvements. Paper production increased 3% in fiscal 1996 as a result of
 capital improvements and full operations, compared to fiscal 1995 when the
 Brokaw and Groveton paper mills operated at 98% and 96% of capacity,
 respectively. In November 1996, an operational problem occurred at the
 Brokaw pulp mill when, during start-up after a normal planned maintenance
 shutdown, cracks developed in two of the mill's four high-pressure cooking

                                   -11-

 vessels known as digesters. The digesters were out of operation until
 April 1997 for repairs, however, no reduction in paper production was
 incurred. The digester incident reduced the company's fiscal 1997 net
 earnings by $.06 per share as a result of curtailed pulp production and
 increased maintenance costs. Printing and Writing Division paper inventory
 levels rose slightly in fiscal 1997, primarily as a result of new product
 additions, increased production and less than robust market conditions.

 The Rhinelander and Otis mills at the company's Technical Specialty
 Division operated at capacity in fiscal 1997. Production increased 12% at
 the Rhinelander mill, compared to the previous year, primarily due to
 capital improvements and a strong mix of pressure sensitive products.
 Including operations from the Otis mill acquired on May 12, 1997,
 production at the Technical Specialty Division increased 27%, compared to
 fiscal 1996 results. Rhinelander's silicone coaters operated approximately
 83% of available machine time in fiscal 1997, compared to 66% a year ago.
 Although shipments of silicone-coated products increased 14%, compared to
 fiscal 1996, the additional volume was not sufficient to sustain full
 operation on the coaters. Paper inventory levels at the Technical
 Specialty Division rose in fiscal 1997, primarily due to the addition of
 the Otis mill and strong operations at the Rhinelander mill.

 Maintenance and repair costs were $35.7 million in fiscal 1997, an
 increase of $4.1 million over fiscal 1996 maintenance costs of $31.6
 million. Higher maintenance costs in fiscal 1997 are mainly due to the
 addition of the Otis mill in May 1997 and costs associated with the
 repairs to two pulp mill digesters at the Brokaw mill. Maintenance and
 repair costs were $30.2 million in fiscal 1995.

      LABOR

 A new five-year labor agreement with the United Paperworkers International
 Union at the Groveton mill was successfully negotiated in fiscal 1997. The
 new agreement became effective April 1, 1997 and includes 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.

      SELLING, ADMINISTRATIVE AND RESEARCH EXPENSES

 Fiscal 1997 selling, administrative and research expenses were $32.5
 million, compared to $29.8 million in fiscal 1996 and $28.0 million in
 fiscal 1995. Higher stock appreciation rights, dividend equivalent and
 stock option discount expense and the addition of the Otis mill are the
 primary reasons for the increased expenses in fiscal 1997, compared to the
 prior year. In fiscal 1997, $1.1 million in expense was recorded for stock
 appreciation rights, dividend equivalent and option discount expense,
 compared to $.1 million in fiscal 1996 and fiscal 1995.
<PAGE>
 Wausau Paper Mills Company, like most companies today, is heavily
 dependent upon computer technology to effectively carry out its day to day
 operations.  Until recently, most purchased and custom designed software
 was not year 2000 compliant, meaning, the software wasn't designed to
 properly handle dates beyond the year 1999.  To ensure its computer
 systems will be ready to handle dates of the year 2000 and beyond, the
 company is well along in its overall plan to upgrade its software to
 become year 2000 compliant.  This process is expected to be completed by
 the end of 1998.  No material costs or effects on operations are expected
 from the upgrade process.

                                  -12-

      INTEREST INCOME AND EXPENSE

 Interest income in fiscal 1997 totaled $.2 million, compared to $.6
 million in fiscal 1996 and $.2 million in fiscal 1995. The decrease in
 interest income in fiscal 1997 is due to more interest income in 1996 than
 in 1997 from a declining balance of undistributed proceeds from a $19
 million industrial development bond issuance in August 1995. Bond proceeds
 were fully disbursed as of January 1997.

 Fiscal 1997 interest expense amounted to $3.5 million, compared to $2.8
 million in fiscal 1996 and $1.7 million in fiscal 1995. Interest expense
 increased in fiscal 1997 due to higher average debt levels as a result of
 the acquisition of Otis Specialty Papers on May 12, 1997, which was
 entirely debt financed. Capitalized interest totaled $.2 million in fiscal
 1997, $.9 million in fiscal 1996 and $.7 million in fiscal 1995.
 Capitalized interest decreased in fiscal 1997 due to several major capital
 projects which were at or nearing completion by the end of fiscal 1996,
 including a capacity expansion at the Rhinelander mill, installation of a
 fiber handling and processing system at the Brokaw mill and upgrades to
 the wastewater treatment plant at both Wisconsin mills.

 Other income of $.2 million was recorded in fiscal 1997, compared to
 expense of $.5 million in fiscal 1996 and fiscal 1995.

      INCOME TAXES

 The tax provision for fiscal 1997 was $29.5 million, for an effective tax
 rate of 37.6%. The effective rates for fiscal years 1996 and 1995 were
 38.3% and 38.5%, respectively. The reduction in the fiscal 1997 effective
 tax rate, compared to the prior year, is due primarily to state
 apportionment changes and a decrease in the ratio of non-deductible items
 to income as a result of increased earnings.

      NET EARNINGS

 Net earnings were a record $48.9 million or $1.34 per share in fiscal
 1997, an increase of 19% compared to net earnings of $41.2 million or
 $1.12 per share recorded in fiscal 1996. Fiscal 1995 net earnings were
 $31.3 million or $.85 per share. Fiscal 1997 net earnings were negatively
 impacted by $.06 per share due to several months of curtailed pulp
 production and increased maintenance costs associated with repairs to two
 digesters at the Brokaw mill.
<PAGE>
 CAPITAL RESOURCES AND LIQUIDITY

      LONG-TERM DEBT

 Long-term debt increased $30.4 million in fiscal 1997 to $83.5 million at
 August 31, 1997. Long-term debt at the end of fiscal 1996 and fiscal 1995
 was $53.1 million and $68.6 million, respectively. Long-term debt
 increased in fiscal 1997 as a result of the May 12, 1997 acquisition of
 Otis Specialty Papers for $55.1 million, which was entirely debt financed.
 The decrease in long-term debt in fiscal 1996 was the result of improved
 cash flow from operations. Long-term debt as a percent of capital was
 16.9% at the end of fiscal 1997, compared to 13.0% in fiscal 1996 and
 18.0% in fiscal 1995.

 At August 31, 1997, the company had $39.0 million outstanding under its
 revolving credit facility.  Long-term debt at the end of fiscal 1997 also
 included $12.0 million in senior promissory

                                  -13-

 notes to Prudential Insurance Company of America and its subsidiaries,
 $19.0 million in industrial development bonds and $13.0 million in
 commercial paper.  Long-term debt at the end of fiscal 1996 consisted
 primarily of $19.0 million in industrial development bonds, $18.0 million
 in senior promissory notes and $13.5 million outstanding under the
 revolving credit facility.

      CASH PROVIDED BY OPERATIONS

 Cash provided by operations was $67.6 million in fiscal 1997, down 15%
 from fiscal 1996 operating cash flow of $80.0 million. Fiscal 1995 cash
 provided by operations was $47.5 million. The reduced operating cash flow
 in fiscal 1997, compared to the previous year, is due mainly to an
 increase in accounts receivable, higher pulp inventories, and increased
 paper inventories at the Printing and Writing Division due to new product
 additions as well as a combination of strong production and moderate
 market conditions. The increase in cash provided by operations in fiscal
 1996 was primarily the result of higher selling prices, a reduction in
 accounts receivable and smaller increases in inventory, compared to fiscal
 1995.

      CAPITAL EXPENDITURES

 Fiscal 1997 capital expenditures totaled $34.3 million, compared to $63.2
 million in fiscal 1996 and $66.1 million in fiscal 1995. Fiscal 1997
 capital expenditures exclude $55.1 million for the acquisition of Otis
 Specialty Papers on May 12, 1997. The decrease in capital spending in
 fiscal 1997, compared to a year ago, is due to a $42 million capacity
 expansion at the Rhinelander mill which was implemented in the second and
 third quarters of fiscal 1996.

 Several major capital improvements were completed in fiscal 1997. A new
 saveall and broke metering system was installed at the Groveton mill,
 reducing operating costs and improving fiber yield. An upgrade to
 Groveton's turbine generator was also completed, lowering the mill's
 electrical costs. At the Rhinelander mill, a new rewinder was brought into
 service to support the mill's silicone coating operation.  At Brokaw, a
 $14 million upgrade of its wastewater treatment facility was completed.
<PAGE>
 In addition, a $6 million upgrade to the mill's wood processing facility
 was finished, resulting in improved wood yield, increased process
 efficiencies and reduced operating costs.

 The company's Board of Directors approved a number of major capital
 improvements in fiscal 1997, spending on which will continue into fiscal
 1998.  A $9 million pulp mill digester and process upgrade project was
 approved for the Brokaw mill. This project will increase pulp production
 capacity by approximately 15%, improve pulp quality and reduce operating
 costs. The new digester and process upgrade are expected to be completed
 in the fourth quarter of fiscal 1998. Over $8 million in capital
 improvements at the Groveton mill will be completed over the next two
 years to expand the mill's paper production capacity by 5%. The capital
 improvements include replacing the electric drive on No. 6 paper machine
 and upgrades to the wet end and dryer systems on No. 5 paper machine.
 These projects will allow both paper machines to operate at faster speeds
 while improving reliability and overall operating efficiency. In addition,
 a new fiber blending system will be installed at the Groveton mill to
 improve production efficiencies and flexibility while lowering overall
 material costs. At the Rhinelander mill, No. 7 and No. 9 paper machines,
 along with two rewinders, will be equipped with state-of-the-art web
 inspection and cleaning equipment, which will further enhance the quality
 of Rhinelander's pressure sensitive products. At the end of fiscal 1997,
 the company was committed to spend $34.0 million to complete these capital
 projects and others currently under construction.

 Capital expenditures are expected to be approximately $150 million over
 the next three years,

                                  -14-

 including about $50 million in fiscal 1998.

      FINANCING

 In fiscal 1997, the company amended its revolving credit facility with its
 four banks, increasing the credit line from $40 million to $105 million.
 The revolving credit line was increased to finance the acquisition of Otis
 Specialty Papers in May 1997. The amended agreement extends through March
 29, 2001 at which time, or earlier at the company's option, the agreement
 converts to a one-year term loan. Interest rates on these borrowings are
 based on domestic rate loans, eurodollar loans, adjusted CD rate loans,
 offered loans or treasury rate loans. 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 August 31, 1997, the
 company had a combined total of $53 million available for borrowing under
 its revolving credit and commercial paper placement agreements.  In a
 separate agreement, one of the four banks participating in the revolving
 credit facility provides a $5 million uncommitted line of credit to the
 company.  In addition, the company also has a $2 million short-term line
 of credit available.  There were no borrowings against these lines at
 August 31, 1997.

 In June 1993, the company borrowed $30 million through the issuance of
 notes to Prudential Insurance Company of America and its subsidiaries. The
 loan was in the form of unsecured term notes bearing a fixed interest rate
<PAGE>
 of 6.03%. Principal is payable in equal semi-annual installments, with the
 final payment due June 16, 2000. Proceeds from the notes were used to
 reduce borrowings from the revolving credit facility.

 In August 1995, the company obtained $19 million in industrial development
 bond financing to fund an upgrade of the Brokaw mill wastewater treatment
 plant, the construction of a new landfill and several other projects which
 qualify for this type of financing. The bonds, which were issued by a
 local governmental unit, mature on July 1, 2023 and have a floating
 interest rate commensurate with short-term municipal bond rates on similar
 issues. The interest rate can be converted to a fixed rate at the option
 of the company.  Principal is due upon maturity or earlier at the
 company's option. Proceeds from the bond issue were held in a trust fund
 until they were drawn upon by the company as spending occurred on these
 projects.  Bond proceeds were fully disbursed as of January 1997.

 Cash provided by operations and the revolving credit facility are expected
 to meet current and anticipated working capital needs and dividend
 requirements, as well as fund the company's planned capital expenditures.
 The company believes additional financing is readily available, should it
 be needed, to fund a major expansion or another acquisition.

      COMMON STOCK REPURCHASE

 On June 30, 1994, the company's Board of Directors authorized the
 repurchase of up to 1,856,250 shares of the company's common stock from
 time to time in the open market or through privately negotiated
 transactions at prevailing market prices. The company did not repurchase
 any shares of the company's common stock in fiscal 1997. In fiscal 1996,
 369,500 shares were repurchased at market prices ranging from $16.750 per
 share to $18.125 per share. The company repurchased 308,938 shares in
 fiscal 1995 at market prices ranging from $16.550 per share to $17.091 per
 share and, in fiscal 1994, 123,750 shares were repurchased at market
 prices ranging from $17.364 per share to $17.909 per share. Shares and per
 share data have been restated to reflect

                                  -15-

 the five-for-four stock split and 10% stock dividend which occurred in
 January 1996 and January 1995, respectively.

      DIVIDENDS

 During fiscal 1997, the company's Board of Directors declared cash
 dividends of $.25 per share, an increase of 13.6% from the $.22 per share
 cash dividend declared in fiscal 1996.

 We conducted our audits in accordance with generally accepted auditing

 In our opinion, the consolidated financial statements referred to above
 present fairly, in all material respects, the financial position of Wausau

                 WAUSAU PAPER MILLS COMPANY AND SUBSIDIARIES
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


 NOTE 1.  SIGNIFICANT ACCOUNTING POLICIES

 CONSOLIDATION - 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.

 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 consolidated 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.

 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.

 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.  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 consolidated statements of income.

 Buildings are depreciated over a 25- to 45-year period; machinery and
 equipment over a 4- 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.

 Land is stated at cost.  Timberlands are at cost less the pro rata cost of
 timber harvested since acquisition.  Depletion expense is calculated using
 the block method, which 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.
<PAGE>
 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

                                  -25-

 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 - Earnings per common share are based on the weighted
 average number of common shares outstanding.  Dilution of earnings per
 common share due to common stock equivalents (stock options) is negligible
 and, accordingly, no dilution has been reported.

 The Financial Accounting Standards Board has issued Statement of Financial
 Accounting Standards (SFAS) No. 128, "Earnings Per Share."  This statement
 is effective for periods ending after December 15, 1997.  If SFAS No. 128
 had been adopted during 1997, the company's reported basic earnings per
 share and diluted earnings per share would have been unchanged at $1.34
 per share.

 FUTURES CONTRACTS - The company utilizes futures contracts to hedge the
 price risk of anticipated purchases of pulp and natural gas.  Because the
 pulp futures markets are very new and liquidity may be limited, the
 company has not hedged substantial quantities of pulp.  Changes in the
 market value of the futures contracts are included as part of the
 acquisition price of pulp and natural gas and are realized when the
 finished paper is sold and the natural gas is consumed.

 The company's long-term debt, excluding current maturities as of August
 31, is outlined below:

 Totals                                 $83,510      $53,119
</TABLE>
 The company has outstanding $18 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
 3.65% at August 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 August 31, 1997, all bond
 proceeds had been disbursed.

 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,
<PAGE>
 offered loans or treasury rate loans.  The weighted average interest rate
 on borrowings under the revolving credit facility was 5.87% and 5.62% at
 August 31, 1997 and 1996, 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 August 31, 1997, the fees are .1% per annum.

 Consistent with the classification of the revolving credit agreement,
 fixed asset payables that will be financed through the agreement are
 classified as long-term debt.

 The senior promissory notes and the revolving credit facility agreement
 require the company to comply with certain covenants, one of which
 requires the company maintain minimum net worth. At August 31, 1997,
 $91,750,000 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 August 31, 1997,
 $13,004,000 was outstanding.  There were no amounts outstanding at August
 31, 1996.  The weighted average interest rate on outstanding commercial
 paper was 5.86% at August 31, 1997.

                                  -27-

</TABLE>
 Annual maturities will be affected by future borrowings.

 A bank participating in the revolving credit agreement has provided a
 separate uncommitted revolving line of credit to the company in the amount
 of up to $5 million.  The specific terms of any revolving loans borrowed
 pursuant to this line of credit will be negotiated at the time of the
 borrowing and any revolving loans so borrowed will be payable on demand.
 In addition, the company has a $2 million line of credit with interest
 payable at the prime rate.  The line does not require a compensating

</TABLE>
 Projected benefit obligations were determined using an assumed discount
 rate of 7.5% and an assumed rate of increases in future compensation
 levels of 5.0%.  The assumed long-term rate of return on plan assets was
 8.0%.  Plan assets consist principally of publicly traded stocks and fixed
 income securities and include Wausau Paper Mills Company common stock with
 a market value of $1,440,300 in 1997 and $1,632,000 in 1996.

 For plans where the accumulated benefit obligation exceeds the fair value
 of plan assets, a minimum pension liability has been established to
 recognize the plans' underfunding, with an offsetting intangible asset
 and reduction to stockholders equity, net of deferred taxes.

 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 $452,000 in 1997, $314,000
 in 1996 and $232,000 in 1995.

 The company has deferred compensation or supplemental retirement
 agreements with certain present and past key officers 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.
<PAGE>
 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.

 For 1997, the assumed health care cost trend rate used in measuring the
 accumulated postretirement benefit obligation was 8% declining by 1%
 annually for three years to an ultimate rate of 5%.  The weighted average
 discount rate was 7.5%.

 For 1996, the assumed health care cost trend rate used in measuring the
 accumulated postretirement benefit obligation was 9% declining by 1%
 annually for four years to an ultimate rate of 5%.  The weighted average
 discount rate was 7.5%.

 A one-percentage-point increase in the assumed health care cost trend
 rates would increase the accumulated postretirement benefit obligation as
 of August 31 by approximately $4,977,000 or 13.7% in 1997 and $3,801,000
 or 12.9% in 1996.  The effect of this change on the aggregate of the
 service and interest cost would be an increase of $498,000 or 15.6% in
 1997 and $441,000 or 15.0% in 1996.

 NOTE 8.  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

 NOTE 9.  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.

 During 1997, 67,000 options were granted under the plan to be earned in
 the current year based upon the satisfaction of operating goals set forth
 in the agreement.  A total of 43,000 options were earned based upon actual
 operating results.  During 1996, 64,375 options were earned based upon the
 satisfaction of operating goals set forth in the agreement.  A total of
 46,062 options granted in 1995 terminated when operating goals were not
 met.

 Effective September 1, 1996, the company has adopted Statement of
 Financial Accounting Standards (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, earnings per
 share would have been reduced by $.01 and $.02 for the years ended
 August 31, 1997 and 1996, respectively.

 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

 The company maintains the 1991 Dividend Equivalent Plan.  Participants are
 entitled to receive cash based on the hypothetical value of cash dividends
 which would have been paid on the stock covered by the grant assuming
 reinvestment in company stock. During 1997, 67,000 dividend equivalents
 were granted under the plan to be earned in the current year based upon
 the satisfaction of operating goals set forth in the agreement.  A total
 of 43,000 dividend equivalents were earned based upon actual operating
 results.  During 1996, 64,375 dividend equivalents were earned based upon
 the satisfaction of operating goals set forth in the agreement.  All
 dividend equivalents granted in 1995 terminated when operating goals were
 not met.

 NOTE 11.  RESEARCH EXPENSES

 Research expenses charged to operations were $1,503,000 in 1997,
 $1,381,000 in 1996 and $1,219,000 in 1995.

 NOTE 12.  COMMITMENTS, CONTINGENCIES AND RELATED PARTY TRANSACTIONS

 On August 24, 1997, Wausau Paper Mills Company, Mosinee Paper Corporation
 ("Mosinee") and WPM Holdings, Inc., a wholly-owned subsidiary of the
 company ("Merger Sub"), entered into an Agreement and Plan of Merger (the
 "Merger Agreement") pursuant to which Merger Sub will be merged with and
 into Mosinee (the "Merger") with Mosinee being the surviving corporation.
 Under the terms of the Merger Agreement, which was unanimously approved by
 the Boards of Directors of the company and Mosinee, each outstanding share
 of Mosinee common stock will be converted into the right to receive 1.4
 shares of Wausau common stock, with cash paid in lieu of fractional
 shares.  The Merger, which is subject to approval by the shareholders of
 both the company and Mosinee, regulatory approval and other customary
 conditions, will be accounted for as a pooling of interests and is
 expected to close by the end of calendar 1997.

 The company is involved in various legal proceedings in the normal course
 of business.  It is the opinion of management that any judgment or
 settlement resulting from pending or threatened litigation would not have
 a material adverse effect on the financial position or on the operations
 of the company.

 As of August 31, 1997, the company was committed to spend approximately
 $34.0 million to complete capital projects which were in various stages of
 completion.

 On November 9, 1996, the company's pulp mill in Brokaw, Wisconsin
 experienced damage to two of its four high-pressure cooking vessels known
 as digesters.  The digesters were out of production for approximately five
 months resulting in a significant loss of pulp production and extensive
 repair work.  Insurance was in effect to cover property damage and
 business interruption costs.  Approximately $3.5 million in pre-tax
 expense was recorded in fiscal 1997 for the potential uninsured operating
 expenses, including insurance deductibles.  The company is in discussions
 with its insurers as to insurance proceeds to which the company believes
 it is entitled.  Insurance proceeds under the company's property damage
 claim will be recorded upon receipt or final settlement of the claim.
 Insurance proceeds under the business interruption claim may exceed the
 insurance recovery receivable recorded in fiscal 1997.  Additional
 proceeds from the business interruption claim will be included in income
 when received but are not expected to be material in amount.
<PAGE>
 In July 1996, the company signed a natural gas transportation agreement
 with the Portland Natural Gas Transmission System (PNGTS).  Under the
 terms of the agreement, PNGTS will construct 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 the 20-year agreement.  Capital improvements to the Groveton
 mill's power plant will be required to take advantage of this agreement.
 Transportation of natural gas to the Groveton mill is scheduled to begin
 in fiscal 1999.

 NOTE 13.  FUTURES CONTRACTS

 At August 31, 1997, the company was party to various futures contracts for
 the purchase of pulp and natural gas.  The pulp contracts require the
 company to purchase 2,424 tons of pulp during fiscal 1998.  The price of
 the pulp varies from $531 to $557 per ton.  The natural gas contracts
 require the company to purchase 1,150,000 decatherms of natural gas during
 fiscal 1998.  The delivered price of 700,000 decatherms varies from $2.77
 to $3.00 per decatherm.  The remaining 450,000 decatherms are to be
 purchased at the lower of the contract cap price of $3.42 per decatherm or
 market.  At August 31, 1997, the company's futures contracts have no
 carrying 

                                  -37-

 value.  The fair value of the contracts and the total deferred
 gain on the contracts are immaterial at August 31, 1997.

 NOTE 14.  MAJOR CUSTOMERS

 One customer accounted for 13.9% of net sales aggregating $79,462,000,
 12.7% of net sales aggregating $68,797,000 and 12.0% of net sales
 aggregating $61,732,000 in 1997, 1996 and 1995, respectively.  Another
 customer accounted for 10.9% of net sales aggregating $62,416,000 and
 11.5% of net sales aggregating $62,563,000 in 1997 and 1996, respectively.

 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.

 Futures contracts - The fair values of the company's pulp and natural gas
 futures contracts were estimated using the prices published by Lynch
<PAGE>
 Futures Inc. and NYMEX, respectively, the contract price and the remaining
 pulp and natural gas to be purchased under the contracts.

</TABLE>
<PAGE>

                                   -4-

        SECTION 4.  DETERMINATION OF INCENTIVE COMPENSATION

 Target Performance Level for such Fiscal Year.


     4.2  DETERMINATION OF THRESHOLD PERFORMANCE LEVEL.  On or before
 October 1st of each Fiscal Year, the Executive Committee shall establish
 the Threshold Performance Level for such Fiscal Year.

                   SECTION 5.  INCENTIVE AWARDS

     5.1  FISCAL YEAR PERFORMANCE.  Each Fiscal Year, as soon as reasonably
 possible following the availability to the Executive Committee of the
 Company's audited financial statements for the Fiscal Year, the Executive
 Committee shall determine the ROA and the Achieved Performance Level for
 the Fiscal Year.

     5.2  DETERMINATION OF ROE INCENTIVE AWARD.  Each Participant shall be
 entitled to receive a ROA Incentive Award in an amount equal to the
 product of (a) the Participant's Salary, as determined prior to any award
 under this Plan, multiplied by (b) the percentage in Column (4) of
 Attachment A which is set forth opposite the percentage in Column (2) of
 Attachment A which corresponds to the Achieved Performance Level for such
 Fiscal Year, multiplied by (c) the percentage specified in section 3.1(b)
 for the Group Participation Level to which the Participant has been
 assigned; provided, however, that:

     (a)  No ROA Incentive Award shall be payable in any Fiscal Year in
          which ROA does not equal or exceed the Threshold Performance
          Level.
<PAGE>
     (b)  If the Achieved Performance Level for the Fiscal Year is not
          expressed as a whole integer (and therefore not specifically set
          forth in Column (2) of Attachment A), the applicable percentage
          of base salary used to determine a Participant's ROA Incentive
          Award shall be determined by interpolation (rounded up to the
          next highest .01%), based on the percentages set forth in Column
          (4) of Attachment A, of the percentage which would correspond to
          the Achieved Performance Level set forth in Column (2) if Column
          (4) specified Achieved Performance Levels at each .01% between
          80% and 120%.

     (c)  A Participant who (1) was a Participant on the last day of Fiscal
          Year, but was not eligible to participate for the entire Fiscal
          Year or (2) transfers to a position

                                   -5-

          in the Company or any subsidiary thereof and is thereafter not
          eligible to participate in the Plan or (3) incurs a termination
          of employment on or before the last day of the Fiscal Year
          because of (A) normal, early or late retirement (or prior to
          becoming eligible for a disability retirement benefit) under the
          terms of any pension plan maintained by the Company or any
          subsidiary thereof as part of a trust qualified under section
          401(a) of the Internal Revenue Code of 1986, as amended, or (B)
          death shall be entitled to receive a prorated ROA Incentive
          Award for such Fiscal Year based on the number of complete
          calendar months in the Fiscal Year in which such Participant or
          former Participant participated in the Plan during such Fiscal
          Year.

     5.3  DISCRETIONARY INDIVIDUAL PARTICIPANT INCENTIVE COMPENSATION
 AWARDS - "PRESIDENTIAL POOL".  Each Fiscal Year, an amount which is not in
 excess of 5% of the aggregate amount of individual ROA Incentive Awards
 for the Fiscal Year awarded pursuant to section 5.2 (the "Presidential
 Pool") may be awarded to one or more Participants who are selected in the
 sole discretion of the President to receive an incentive award pursuant to
 this section 5.3.  The Participants who shall be entitled to receive such
 awards, if any, and the basis upon which such awards shall be determined
 shall be the sole and exclusive province of the President.  If less than
 the amount provided for as the Presidential Pool in this section 5.3 is
 awarded with respect to a Fiscal Year, any amount not awarded to
 Participants shall lapse and shall not be paid under any other provision
 of this Plan.

<PAGE>
          of base salary used to determine a Participant's ROA Incentive
          Award shall be determined by interpolation (rounded up to the
          next highest .01%), based on the percentages set forth in Column
          (4) of Attachment A, of the percentage which would correspond to
          the Achieved Performance Level set forth in Column (2) if Column
          (4) specified Achieved Performance Levels at each .01% between
          80% and 120%.

                                   -5-

     (c)  A Participant who (1) was a Participant on the last day of Fiscal
          Year, but was not eligible to participate for the entire Fiscal
          Year or (2) transfers to a position in the Company or any
          subsidiary thereof and is thereafter not eligible to participate
          in the Plan or (3) incurs a termination of employment on or
          before the last day of the Fiscal Year because of (A) normal,
          early or late retirement (or prior to becoming eligible for a
          disability retirement benefit) under the terms of any pension
          plan maintained by the Company or any subsidiary thereof as part
          of a trust qualified under section 401(a) of the Internal Revenue
          Code of 1986, as amended, or (B) death shall be entitled to
          receive a prorated ROA Incentive Award for such Fiscal Year based
          on the number of complete calendar months in the Fiscal Year in
          which such Participant or former Participant participated in the
          Plan during such Fiscal Year.

     5.3  DISCRETIONARY INDIVIDUAL PARTICIPANT INCENTIVE COMPENSATION
 AWARDS - "PRESIDENTIAL POOL".  Each Fiscal Year, an amount which is not in
 excess of 5% of the aggregate amount of individual ROA Incentive Awards
 for the Fiscal Year awarded pursuant to section 5.2 (the "Presidential
 Pool") may be awarded to one or more Participants who are selected in the
 sole discretion of the President to receive an incentive award pursuant to
 this section 5.3.  The Participants who shall be entitled to receive such
 awards, if any, and the basis upon which such awards shall be determined
 shall be the sole and exclusive province of the President.  If less than
 the amount provided for as the Presidential Pool in this section 5.3 is
 awarded with respect to a Fiscal Year, any amount not awarded to
 Participants shall lapse and shall not be paid under any other provision
 of this Plan.

     5.4  PAYMENT OF AWARDS.  Payment of incentive awards shall be made to
 each Participant by the respective employer of such Participant as soon as
 administratively feasible following the determination of the amount of
 such awards.  Any payment due a Participant at or after the time of his

 estate.

 adopted.

                   SECTION 8.  EMPLOYMENT RIGHTS

     Wausau Paper Mills Company, a Wisconsin corporation (the "Company"),
 hereby adopts the Wausau Paper Mills Company 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

                                   -1-

 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") 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.
<PAGE>
     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.

                                   -2-

     Section 4.  ELIGIBLE EMPLOYEES.

     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.

     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

                                   -3-

 "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

 at any time thereafter impose such additional terms and conditions on the

 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.

 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.
<PAGE>
          (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.

                                   -4-

     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 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

                                   -5-

          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
<PAGE>
          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 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

                                  -6-

          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 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.  No option shall be exercisable unless the
     Optionee shall have been employed by the Company (or any present or

                                   -7-

     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 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 (i) 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 and (ii) 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.
<PAGE>
          (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

                                   -8-

     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 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.

                                   -9-

     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, 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.
<PAGE>
     Section 8.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION.  If any option
 is exercised in whole or in part subsequent to any

                                  -10-

 stock dividend, stock split, recapitalization, reorganization, merger or
 other change in the corporate structure of the Company as a result of
 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 payable upon such
 exercise, the aggregate number and class or classes 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 the option is so exercised
 and the Shares so purchased had not been disposed of as of the date of
 such actual exercise, taking into consideration such stock dividend,
 stock split, recapitalization, reorganization, merger or other change in
 the corporate structure of the Company.

     Section 9.  TERMINATION OR LAPSE OF OPTIONS.  Each option shall
 terminate or lapse upon the first to occur of (a) the expiration date set
 forth in the applicable Stock Option Agreement, (b) the applicable date
 set forth in Section 6.2(b), or (c) the date which is the day next
 following the last day such option could be exercised by the Optionee
 under Section 6.2(e); provided, however, that in the event of an
 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

                                  -11-

 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 such option
 pursuant to Section 6.2(d)(ii), but only if the date of exercise is on or
 before the first to occur of (i) the expiration date set forth in the
 applicable Stock Option Agreement, (ii) the applicable date set forth in
 Section 6.2(b), or (iii) the date which is twelve months after the date
 of the Optionee's death.

     Section 10.  AMENDMENT AND TERMINATION OF PLAN.

     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.

     Section 10.2  TERMINATION OF PLAN.  The Plan shall terminate on the
 first to occur of (a) June 18, 2001 or (b) the date specified by the Board
 of Directors of the Company as the effective date of Plan termination;
<PAGE>
 provided, however, that the termination of the Plan shall not limit or
 otherwise affect any options outstanding on the date of termination.

                                  -12-

     Section 11.  EFFECTIVE DATE.  The Effective Date of the Plan shall be
 June 19, 1991, the date of approval by the Board of Directors of the
 Company; provided, however, that neither the Plan nor grants made under
 the Plan shall be effective unless the adoption of the Plan is approved at
 the annual meeting of the Company's shareholders next following such date
 by the majority of the shares entitled to vote at such meeting.

     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 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 agreement
 provided for in Section 6.1 is executed by the Optionee and (b) a copy of
 each subsequent annual report, on or about the same date as such report
 shall be made available to shareholders of the Company.  The Company will
 furnish, upon written request addressed to the Secretary of the Company,
 but at no charge to the Optionee or any duly authorized representative

                                  -13-

 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 if the
 Plan and any options granted pursuant to it were not in effect.

     IN WITNESS WHEREOF, the Company has caused the Plan, as amended
 September 15, 1997, to be executed by its duly authorized officers as of
 the 15th day of September, 1997.

               GENERAL RELEASE AND WAIVER AGREEMENT


     This General Release and Waiver Agreement (Agreement) is entered into
 this 25th day of October, 1997, between Daniel D. King (hereinafter
 defined as King) and Wausau Paper Mills Company, including, but not
 limited to, its present and future divisions, operations, parents,
 subsidiaries, affiliates, predecessors, successors, assigns, employee
 benefit plans, employee benefit plan administrators, employee benefit plan
 sponsors, directors, officers, trustees, agents, employees or
 representatives (collectively defined as Wausau Paper).  The Parties have
 entered into this Agreement to fully and finally settle any differences
 between them that have arisen or might arise from King's employment
 relationship and/or conclusion of that employment relationship, without
 either party incurring further expense.  The Parties have agreed to the
 following terms and conditions:

     1.   It is understood and agreed upon by the Parties that King will
 resign his employment and officer status and all positions with Wausau
 Paper, effective February 15, 1998, and the sole purpose for Wausau Paper
 entering into this Agreement is to confer certain transitional benefits to
 King and to avoid any potential for time-consuming and costly litigation
 in defending Wausau Paper's position that no unlawful acts occurred
 related to King's employment or the conclusion of that employment.  It is
 further understood and agreed that neither the negotiations or signing of
 this Agreement, nor any actions taken in fulfillment of the
 representations contained herein, shall constitute an admission, in any
 fashion, by Wausau Paper that it has acted wrongfully or unlawfully toward
 King or any other person, and the parties recognize that King resigned,
 effective February 15, 1998, for legitimate reasons.  Wausau Paper
 disclaims any liability to, or wrongful or unlawful conduct against King,
 and King disclaims any liability to, or wrongful or unlawful conduct
 against Wausau Paper.

     2.   In consideration for the promises set forth in this Agreement,
 Wausau Paper will provide King with the following:

          A.   King will remain employed as provided in Paragraph 3A with
 Wausau Paper through February 15, 1998.  King shall be paid his current
 annualized base salary of $290,000 on a bi-weekly basis through November
 30, 1997.  Each payment shall be in the amount of $11,153.85 (Eleven
 Thousand One-Hundred Fifty-Three and 85/100th Dollars), less applicable
 taxes and deductions withheld.  Commencing December 1, 1997 and through
 February 15, 1998, King shall be paid an annualized base salary of
 $490,000, and it will be paid bi-weekly.  Each payment shall be paid in
 the amount of $18,846.15 (Eighteen Thousand Eight Hundred Forty-Six and
 15/100th Dollars), less applicable taxes and deductions withheld.  In
 addition, through February 15, 1998, Wausau Paper will continue to provide
 King and his spouse with his current active employee benefit package
 (including 401(k) participation), as it may be amended from time to time
 or any successor plan, and pursuant to the terms of the Plan documents.
<PAGE>
 Commencing February 16, 1998, and ending on November 30, 1998 (the
 "Benefit Period"), King shall be paid severance pay in the total amount of
 $395,769.25, and it shall be 

                                   -1-

 paid in equal installments, less applicable taxes and deductions
 withheld, and consistent with Wausau Paper's normal and customary
 payroll practices and periods.  During the Benefit Period,
 Wausau Paper will continue to provide King with health, dental and life
 insurance benefits consistent with the plan(s) he is under at the time of
 his termination and as those plans may be amended from time to time or
 under any successor plan, and pursuant to the terms of the Plan documents.
 Commencing November 30, 1997, Wausau Paper will provide King with
 individual executive level assistance outplacement services with
 Challenger, Gray, & Christman until King secures employment as a senior
 executive.  These payments and benefits shall be made pursuant to
 Subparagraphs 2B, 3C and 3H of this Agreement.  No monies or benefits
 other than those specifically set forth in this Agreement will be paid or
 provided to King.

          B.   King is fully vested in Wausau Paper's qualified retirement
 plan and shall be eligible for a lump sum or payment of benefits beginning
 at age 55 in accordance with the terms of the qualified retirement Plan
 documents.  On or about December 1, 1997, King shall be eligible for a
 lump sum payout of $766,134.38, less applicable taxes and deductions
 withheld, pursuant to the Wausau Paper's Executive Officer Supplemental
 Retirement Plan in accordance with the terms of the Supplemental
 Retirement Plan documents.  This payment and benefit shall be made on or
 after December 1, 1997 but no later than December 15, 1997 and pursuant to
 Subparagraphs 3(C) and 3(H) of this Agreement.  Life, health and dental
 insurance benefit coverage set forth in Subparagraph 2A of this Agreement
 shall cease upon King's obtaining any employment in the capacity of a
 senior executive.

          C.   Wausau Paper agrees that King has the full consent of the
 Option Committee to exercise stock options by delivering other stock of
 Wausau Paper at the purchase price pursuant to the terms of his option
 agreements should he choose to do so.  For purposes of exercising his
 stock options, King shall have until May 15, 1998 in accordance with the
 terms of his options.  King preserves all existing rights to exercise his
 stock options, stock appreciation rights, and dividend equivalent rights
 consistent with the terms of those Plan document(s), except as otherwise
 provided in this Paragraph.

     3.   In consideration for the terms and conditions set forth in this
 Agreement, King and Wausau Paper further agree to the following:

          A.   King agrees that he will resign as a director of Wausau
 Paper as of the effective date of the merger of Mosinee Paper Corporation
 and WPM Holdings, Inc., or, if later, February 15, 1998.  King agrees that
 he will serve as President and Chief Executive Officer of Wausau Paper
 through November 30, 1997 and as Vice Chairman of Wausau Paper through
 February 15, 1998 and will resign his employment and officer status as
 well as any other positions with Wausau Paper, effective February 15,
 1998.  Upon execution of this Agreement, King will sign and tender Exhibit
 A to Wausau Paper.

                                   -2-
<PAGE>
          B.   King agrees that his separation from employment with Wausau
 Paper is complete and permanent; that he will not be reemployed by Wausau
 Paper, and that he will not knowingly apply for, or otherwise seek,
 employment with Wausau Paper at any time.

          C.   King understands and agrees that he has twenty-one (21) days
 during which he can decide whether or not to enter into this Agreement and
 during which time he may consult with an attorney regarding all aspects of
 this Agreement, and agrees to the extent he desires, he will and/or has
 availed himself of that right.  Should King sign this Agreement before the
 end of this twenty-one (21) day period, he represents that he has done so
 voluntarily and without influence by Wausau Paper.  King also understands
 that he has seven (7) days following the signing of this Agreement to
 revoke his agreement to its provisions.  Any such revocation must be made
 by delivering a written notice of revocation to Larry A. Baker, Senior
 Vice President of Administration, Wausau Paper, Corporate Headquarters,
 One Clark's Island, P.O. Box 1408, Wausau, WI 54402-1408.  For the
 revocation to be effective, it must be received by Wausau Paper on or
 before the seventh (7th) calendar day after King executes this Agreement.
 Absent any such revocation, at the conclusion of the seven (7) day period,
 this Agreement shall become effective and enforceable, and the
 consideration set forth in Paragraph 2 of this Agreement shall be provided
 to King at the latter of the expiration of the seven (7) day revocation
 period or as otherwise provided herein.

          D.   King specifically warrants and represents that he has not
 filed, nor will he file at any time hereafter, any claims, charges,
 complaints, suits, or other actions against Wausau Paper with any Federal,
 State, or Local agency or court other then claims, charges, complaints,
 suits, or other actions to enforce the terms of this Agreement or which
 accrue after the signing of this Agreement.  King also expressly agrees
 that he will withdraw with prejudice, or request the withdrawal with
 prejudice, and/or dismissal with prejudice, or cause to be dismissed with
 prejudice, any and all claims, charges, complaints, suits, or other
 actions pending against Wausau Paper in any Federal, State, or Local,
 agency or Court to the extent he has the power to do so, other than
 claims, charges, complaints, suits or other actions that survive the
 signing of this Agreement.  King further agrees that should any claims,
 charges, complaints, suits, or other actions have been filed or filed
 hereafter on his behalf covering any of the claims released hereunder by
 any Federal, State, or Local agency, that he will withdraw with prejudice,
 or cause to be withdrawn with prejudice, and/or dismiss with prejudice, or
 request the dismissal with prejudice any such claims, charges, complaints,
 suits, or other actions filed against Wausau Paper to the extent he has
 power to do so.

          E(1).  King agrees that by the signing of this Agreement, and his
 acceptance of the benefits set forth in Paragraph 2 of this Agreement, he
 irrevocably and unconditionally releases forever, with prejudice, Wausau
 Paper from all damages, actions, lawsuits or claims King may have, whether
 based on contract, tort, statute, or common law, arising from his
 employment with Wausau Paper and/or the conclusion of that employment.
 This includes a release of any rights or claims King may have under the
 Age Discrimination in Employment Act of 1967, as amended, which prohibits
 age discrimination in employment; Title VII of the Civil

                                   -3-
<PAGE>
 Rights Act of 1964, as amended, which prohibits discrimination in
 employment based upon race, color, religion, national origin or sex; the
 Americans with Disabilities Act; the Wisconsin Fair Employment Act, or
 any other charges, complaints, claims, liabilities, obligations,
 promises, agreements, controversies, damages, actions, suits, rights,
 demands, losses, debts and/or expenses (including attorneys' fees and
 costs actually incurred) of any nature, known or unknown, suspected or
 unsuspected which King may have under any other federal, state or local
 law.  King also acknowledges and agrees that the payments and benefits
 extended to him under the terms of this Agreement are in addition to
 anything of value to which he is already entitled.  This also includes a
 release by King of any other known or unknown claims in contract, tort,
 or common law, including, but not limited to, actions for libel, slander,
 defamation, small claims, or wrongful discharge accruing through the date
 of his signing this Agreement.  THIS MEANS THAT KING IS GIVING UP ANY AND
 ALL RIGHTS HE MAY HAVE TO SUE WAUSAU PAPER RELATED TO, IN ANY WAY, HIS
 EMPLOYMENT WITH WAUSAU PAPER AND/OR THE CONCLUSION OF THAT EMPLOYMENT.
 This waiver does not apply to claims or rights, including but not limited
 to, those under the Age Discrimination in Employment Act of 1967, that
 may accrue after this Agreement is executed, claims under the Wisconsin
 Workers Compensation Act or claims to enforce the terms of this
 Agreement.  The Parties agree that King retains all existing
 indemnification rights relating to his service as an employee, officer
 and director of Wausau Paper, including any rights or claims he may have
 under applicable insurance policies covering Directors or Officers
 involving a claim by a third party.  Wausau Paper and King have the right
 to enforce this Agreement solely by way of lawsuit filed in either the
 Circuit Court for Marathon County, State of Wisconsin, or the United
 States District Court for the Western District of Wisconsin, pursuant
 to the terms set forth in Paragraph 5 of this Agreement, and the only
 cause of action that will remain will be to enforce the terms of this
 Agreement, any claims accruing after the date of King's signing of this
 Agreement, or any claims arising under the Wisconsin Worker's
 Compensation Act.

          E(2).  The Board of Directors and Officers of Wausau Paper
 warrants and represents that they have no knowledge, at the time of the
 signing of this Agreement, that King has participated or engaged in any
 type of misconduct, malfeasance, violation of Wausau Paper's policies or
 illegal acts.  King warrants and represents to Wausau Paper that he has
 not participated or engaged in any type of misconduct, malfeasance,
 violation of Wausau Paper's policies or illegal acts.  In reliance on
 these warranties and representations by King, Wausau Paper agrees to, by
 the signing of this Agreement and its acceptance of King's resignations,
 representations, covenants, releases, and waivers provided by King
 hereunder, irrevocably and unconditionally releases forever, with
 prejudice, King from all damages, actions, lawsuits or claims Wausau Paper
 may have, whether based on contract, tort, statute, or common law, arising
 from his employment with Wausau Paper and/or the conclusion of that
 employment, or from his service as an Officer and Director of Wausau
 Paper.  This includes, but is not limited to, a release of any rights or
 claims Wausau Paper may have under applicable law, or any other charges,
 complaints, claims, liabilities, obligations, promises, agreements,
 controversies, damages, actions, suits, rights, demands, losses, debts
 and/or expenses (including attorneys' fees and costs actually incurred) of
 any nature, known or unknown, suspected or unsuspected which Wausau Papers
 may have under any federal, state or local law.  This release also
 includes a

                                   -4-
<PAGE>
 release by Wausau Paper of any other known or unknown claims in contract,
 tort or common law, including, but not limited to, actions for
 libel, slander, defamation or small claims accruing through the date of
 its signing of this Agreement.  Wausau Paper is giving up any and all
 rights it may have to sue King related to, in any way, his employment with
 Wausau Paper and/or the conclusion of that employment, or his service as
 an Officer or Director of Wausau Paper.  This waiver does not apply to
 claims or rights that accrue after the date Wausau Paper signs this
 Agreement or claims to enforce the terms of this Agreement brought by
 Wausau Paper.

          F.   Wausau Paper agrees that it will not intentionally disparage
 King, and King agrees that he will not intentionally disparage Wausau
 Paper or any of its officers, directors, trustees, agents and/or
 employees, with anyone who is presently doing business with or employed by
 Wausau Paper, or with anyone that could reasonably be expected to do
 business with or be employed by Wausau Paper.

          G.   King agrees to direct all reference checks and business-
 related communications to Larry Baker, Senior Vice President of
 Administration of Wausau Paper, or his successor.  Wausau Paper agrees to
 provide King with an executed original of a mutually acceptable letter of
 reference in the form attached to this Agreement as Exhibit B, and Wausau
 Paper agrees to respond to any reference requests only by providing a
 letter having the contents of Exhibit B.

          H.   King acknowledges and agrees that the severance pay and
 benefits set forth in Paragraph 2 of this Agreement are subject to offset,
 termination, cancellation or recoupment in the event that he takes any
 action or engages in any conduct which a court of competent jurisdiction
 holds to be a violation of subparagraphs 3J and 3K of this Agreement.
 However, King retains his right to contest any such action by Wausau Paper
 consistent with Paragraph 3(E) of this Agreement.  Before Wausau Paper
 takes action to offset, terminate, cancel or recoup any of the severance
 pay or benefits set forth in Paragraph 2 of this Agreement, it will
 provide King with a fourteen (14) day written notice so that the parties
 can attempt to reach a mutually satisfactory solution.  With respect to
 any other alleged violations of this Agreement, Wausau Paper shall be
 limited to recovering only its actual damages suffered, as determined by a
 court of competent jurisdiction, as a result of the violation, as well as
 any other damages or remedy provided in any other paragraph of this
 Agreement or by law.

          I.   KING REPRESENTS AND AGREES THAT PRIOR TO THE EXECUTION OF
 THIS AGREEMENT HE HAS BEEN FULLY ADVISED TO CONSULT WITH AN ATTORNEY TO
 DISCUSS ALL ASPECTS OF THIS AGREEMENT.  KING FURTHER REPRESENTS AND AGREES
 THAT, TO THE EXTENT HE DESIRES, HE HAS AVAILED HIMSELF OF THAT RIGHT.
 KING FURTHER REPRESENTS AND AGREES THAT HE HAS EXECUTED THIS AGREEMENT
 WITH FULL KNOWLEDGE OF THE RIGHTS WAIVED HEREUNDER, AND THAT THIS
 AGREEMENT CONSTITUTES A FULL AND FINAL SETTLEMENT OF ALL MATTERS BETWEEN
 WAUSAU PAPER AND KING, INCLUDING, BUT NOT LIMITED TO, ATTORNEYS FEES AND
 COSTS, AND

                                   -5-

 THAT NO OTHER MONIES ARE DUE AND OWING TO HIM OTHER THAN THOSE SET FORTH
 IN THIS AGREEMENT.  KING FURTHER REPRESENTS AND AGREES THAT HE
 HAS READ CAREFULLY AND FULLY UNDERSTANDS ALL OF THE PROVISIONS OF THIS
 AGREEMENT AND THAT HE HAS KNOWINGLY AND VOLUNTARILY ENTERED INTO THIS
 AGREEMENT.
<PAGE>
          J.   King agrees that he shall not disclose to any person, copy,
 retain, or use for his own benefit or the benefit of any other person, any
 secret or confidential information, formulae, designs, drawings, programs,
 specifications, processes, apparatus, research or other trade secrets
 without prior written consent of Wausau Paper.  King agrees that he shall
 not disclose confidential information about Wausau Paper, its products,
 financial status, or other similar information.  The Parties further agree
 that, unless otherwise required by law, they shall keep confidential the
 settlement of this matter and this Agreement, including its terms, amounts
 and conditions.  The Parties agree that they will not reveal any
 information concerning this Agreement, or information contained therein,
 to anyone except King's spouse, prospective employers, the Officers and
 Directors of Wausau Paper, tax advisors or accountants, legal counsel,
 and/or those individuals at Wausau Paper who would have a need to know for
 purposes of implementing or administering the terms of this Agreement,
 provided that any such recipient agrees to keep the information
 confidential.

          K.   King agrees that during his employment with Wausau Paper
 and:

        (a)(i) Through November 30, 1999, he shall not directly or
               indirectly (so as to order or control the activities that

               render any types of services, whether as an employee,
               officer, agent, representative, consultant, independent
               contractor, or in any other capacity, by or on behalf of any
               persons, entities, their parents, subsidiaries, divisions,
               affiliates, operations or successors, related to the

         (iii) Nothing in this Subparagraph shall prevent King from

               identified in this Paragraph, subject to the same
               limitations contained in Subparagraph (c) of this Paragraph.

          (b)  Through November 30, 1998, hire, seek to employ or induce

          (c)  Through November 30, 1999, request, solicit or advise any of
               the Wausau Paper customers listed in Subparagraph 3K(a)(i)
               or serviced by a merchant distributor, with whom King is
               working with or for, to withdraw, curtail, cease or cancel
               business with Wausau Paper.  Nothing in this Subparagraph 3K
               of this Agreement shall be construed as limiting King's
               right to accept employment with the entities listed in
               Subparagraph 3K(a)(i) of this Agreement, subject to the
               limitations set forth in this Subparagraph 3K(c).

                                   -7-

 acknowledges and the Parties agree that the entities listed in
 Subparagraphs 3K(a)(i) and (h) of this Agreement are customers or
 competitors of Wausau Paper.  The Parties agree that the covenant not to
 compete contained in Subparagraph 3K of this Agreement shall be the only
 covenant not to compete governing King, and it is intended to supersede
 any restrictive covenant inconsistent with the foregoing.  The Parties
 further agree that if King becomes employed by a competitor not listed in
 Subparagraph 3(K)(ii) and that unlisted competitor is subsequently
 purchased, acquired, merged or ownership is otherwise transferred to a
 listed competitor, it shall not be a violation of this Agreement for King
 to remain employed in the same capacity he held prior to the transaction;
 however, King is still required to comply with all of his obligations
 under this Agreement.

     4.   The consideration extended by Wausau Paper to King is contingent
 upon his voluntarily and knowingly entering into this Agreement and is
 not, in any manner, indicative of a continuing employment relationship
 with Wausau Paper beyond February 15, 1998.

 and appropriate to carry out his duties as President and Chief Executive
 Officer and, between December 1, 1997 and February 15, 1998, King will
 assist Wausau Paper in an orderly transition and will not intentionally
 engage in any action that would tend to disrupt or interfere with Wausau
 Paper's business.  Wausau Paper agrees to allow King a reasonable amount
 of time to interview while he still is employed with Wausau Paper.

     7.   Following reasonable notice, and recognizing that King may be
 employed elsewhere after February 15, 1998:

     (i)  King agrees to reasonably cooperate with regard to any matter
          which King may have relevant information as a result of his
          employment with Wausau Paper, and

     (ii) King shall provide such reasonable cooperation from the date of
          execution of this Agreement until termination of salary
          continuation payments under Subparagraph 2A of this Agreement,
          after which time Wausau Paper shall compensate King at the rate
          of $200.00 (Two Hundred and No/100 Dollars) per hour for time
          spent by King in providing his reasonable cooperation upon the
          request of Wausau Paper.

    (iii) Reasonable expenses incurred by King while reasonably
          cooperating with Wausau Papers shall be promptly reimbursed by
          Wausau Paper.

                                   -8-

     8.   Each party will indemnify and hold harmless the other party from
 and against all losses, costs, fees, (including, but not limited to,
 reasonable attorney fees) and damages incurred by each party as a result
 of any breach of this Agreement by the other party, as determined by a
 court of law.

     9.   This Agreement sets forth the entire agreement between the
 Parties as of the date of its execution and fully supersedes any and all
 prior discussions, letters, agreements or understandings between the
 Parties, except the Wausau Paper Mills Company Patent and Secrecy
 Agreement dated June 20, 1983, Wausau Paper Mills Company Employee Conduct
 Agreement dated March 4, 1985, and the Wausau Paper Mills Company
 Corporate Compliance Manual and Code of Conduct, dated December 20, 1993.

 of the Agreement is to be found unenforceable, the other Paragraphs of
 this Agreement shall remain valid and fully
 enforceable.
