 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.

 This report on Form 10-K does not reflect any effect the proposed merger
 with Mosinee may have on the company.

                                   -1-

 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.

 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

 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.

 Eligible employees participate in retirement plans and group life,
 disability and medical insurance programs.

 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.

 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.

 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.

 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.

 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.

 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

 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.

     REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

 WIPFLI ULLRICH BERTELSON LLP


 To the Shareholders and Board of Directors
 Wausau Paper Mills Company
 Wausau, Wisconsin

 We have audited the accompanying consolidated balance sheets of Wausau
 Paper Mills Company and Subsidiaries as of August 31, 1997 and 1996, and
 the related consolidated statements of income, cash flows and
 shareholders' equity for each of the years in the three-year period ended
 August 31, 1997 and the supporting schedule listed in the accompanying
 index to financial statements.  These financial statements and supporting
 schedule are the responsibility of the company's management.  Our
 responsibility is to express an opinion on these financial statements and
 supporting schedule based on our audits.

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

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

 We hereby consent to the incorporation by reference of this report in the
 Registration Statements on Form S-8 and amendments thereto filed with the
 Securities and Exchange Commission by Wausau Paper Mills Company on April
 26, 1996, March 18, 1996, August 25, 1995, January 3, 1992 and January 27,

                 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.

 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.

 Net inventories                         $ 84,112      $ 70,443


 Because various components of the inventories are valued by use of the
 last-in, first-out (LIFO) method, it is impracticable to segregate the
 LIFO reserve between raw materials and work in process and finished goods.

                                  -26-


 NOTE 4.  DEBT

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

 (all dollar amounts in thousands)         1997         1996
                                               
 6.03% Senior promissory notes          $12,000      $18,000
 Industrial development bonds            19,000       19,000
 Revolving credit facility agreement     39,000       13,500
 Commercial paper                        13,004
 Fixed asset payables to be financed
   with revolving credit agreement          421        2,244
 Capitalized leases                          85          375

 Totals                                 $83,510      $53,119

 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,

 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-



 The aggregate annual maturities of long-term debt are as follows:
                                                 
 (all dollar amounts
 in thousands)          1998     1999     2000      2001     2002  Thereafter

                      $6,290   $6,085   $6,000   $13,106  $39,319     $19,000

 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
 balance or a commitment fee.  There was no borrowing against these lines
 at August 31, 1997.


 NOTE 5.  LEASE COMMITMENTS

 The company has various leases for real estate, mobile equipment and
 machinery which generally provide for renewal privileges or for purchase
 at option prices established in the lease agreements.  Property, plant and
 equipment includes the following amounts for capitalized leases:

 NOTE 7.  RETIREMENT PLAN

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

 The company selected measurement dates of plan assets of May 31, 1997 and
 1996.

 The components of net periodic pension cost follow:

 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.

 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.

                                  -30-


 Postretirement benefit cost includes the following components:

 Accrued postretirement benefit liability          $  34,319   $ 31,849

 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

 current enacted tax rates.  Deferred tax expense is the result of changes
 in the deferred tax asset and liability.

                                  -31-

 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.

 All shares and option prices have been restated to reflect the
 five-for-four stock split occurring in 1996 and the 10% stock dividend
 occurring in 1995.

 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 weighted-average grant-date exercise prices and weighted-average fair
 values for options granted are as follows:

                                              1997             1996
                                                        
 Exercise price equals market price
     Exercise price                           ----            $18.50
     Fair Value                               ----              7.21
 Exercise price less than market price
     Exercise price                          $17.69           $19.36
     Fair value                                8.67             8.14


 The fair value of each option grant has been estimated on the grant date
 using the Black-Scholes option pricing model based on the following
 weighted-average assumptions:

                                           1997      1996
                                               
 Risk-free interest rate                   6.27%     5.97%
 Expected life in years                       5         5
 Price volatility                          32.1%     31.5%
 Dividend yield *                             0         0
<FN>
 *  Dividend yield is assumed to be zero because dividend equivalents
    were granted in tandem with the options granted. As such,
    dividends do not reduce the economic value of the options.

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

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

 five-for-four stock split occurring in 1996 and the 10% stock dividend
 occurring in 1995.


 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.

 All shares have been restated to reflect the five-for-four stock split
 occurring in 1996 and the 10% stock dividend occurring in 1995.

 The pre-tax impact on earnings of all stock option discounts, dividend
 equivalents and stock appreciation rights for the years ended August 31,
 1997, 1996 and 1995 was expense of $1,092,000, $78,000 and $79,000,
 respectively.

 NOTE 10.  ACQUISITION OF OTIS SPECIALTY PAPERS

 On May 12, 1997, the company acquired the business and assets of Otis
 Specialty Papers ("Otis").  The acquisition was accounted for using the
 purchase method of accounting.  The financial statements reported herein
 include the net sales, operating profit and net earnings of Otis from the
 date of purchase.  The following table presents unaudited pro forma
 condensed results of operations for the years ended August 31, 1997 and
 1996 as if the acquisition were completed at the beginning of the period:

 Net Earnings                      51,005               40,961
 Net Earnings per Common Share   $   1.40             $   1.11


 The unaudited pro forma financial information includes certain assumptions
 or adjustments, not material in amount, which the company believes are
 necessary to fairly present such information.  Historical costs
 representing the seller's corporate allocations, interest expense and
 one-time expenses related to the sale of Otis are included in the pro
 forma information.  The pro forma information does not purport to
 represent what the company's results of operations would actually have
 been if this transaction had occurred at the beginning of the earliest
 period presented.

 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.

                                  -36-

 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.

 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

 Futures Inc. and NYMEX, respectively, the contract price and the remaining
 pulp and natural gas to be purchased under the contracts.
