 ITEM 1.  BUSINESS.

 GENERAL DEVELOPMENT OF BUSINESS

 The Company manufactures, converts, and sells paper.  Its principal
 office is located in Mosinee, Wisconsin.  At December 31, 1999, the
 Company had approximately 3,400 employees at eleven facilities located
 in six states.

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

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

 This report contains certain of management's expectations and other
 forward-looking information regarding the Company.  See the subheading
 "Cautionary Statement Regarding Forward-looking Statements" in this
 Item 1.

 FINANCIAL INFORMATION ABOUT SEGMENTS

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

 NARRATIVE DESCRIPTION OF BUSINESS

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

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

 SPECIALTY PAPER GROUP

 During 1999, the Specialty Paper Group consisted of the Company's
 Mosinee, Sorg, Rhinelander, and Otis facilities to produce a wide
 variety of technical specialty papers.  The Group is a leader in many
 of its markets, although market position varies by product.

 On March 15, 2000, the Company announced its intention to close the
 Sorg Paper Company mill in Middletown, Ohio on May 15, 2000.  Sorg
 operated at a loss in 1999 and the Company was unsuccessful in finding
                                     -1-
 a buyer for the Sorg business.  With the closing, the Company will no
 longer operate in the decorative laminate and deep color tissue markets
 of the industry. The Rhinelander and Otis mills together are one of the
 nation's largest manufacturers of supercalendered backing papers for
 pressure sensitive labeling applications.  These facilities, located at
 Rhinelander, Wisconsin, and Jay, Maine, also manufacture specialty
 paper for a broad range of food, medical, and industrial applications,
 including protective barrier papers for pet food and microwave popcorn,

 and lightweight paper for sterilized medical packaging.  Products,
 markets and distribution methods and principal competitors for the
 Rhinelander and Otis mills can be summarized as follows:

 PRINCIPAL PRODUCTS
 Pressure-sensitive backing, silicone-coated release papers,
 grease-resistant packaging, food service papers, sterilizable medical
 packaging, electrographic and translucent papers, industrial crepe and
 crepe tape backing.

 PRINCIPAL MARKETS & DISTRIBUTION METHODS
 Sold directly to converters, mainly in the U.S., for the following
 industries: pressure-sensitive labeling, convenience food, food
 service, pet food, medical packaging, and specialized converters.

 PRINCIPAL COMPETITION
 Competition comes from large integrated companies such as International
 Paper Corporation, Fraser Paper, Inc., UPM-Kymmene, EB Eddy, Crown
 Vantage Corporation, and SAPPI, Ltd.

 The Mosinee mill in Mosinee, Wisconsin, is one of the nation's largest
 producers of masking tape base and manufactures a wide 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.  Products, markets
 and distribution methods and principal competitors for the Mosinee mill
 can be summarized as follows:

 PRINCIPAL PRODUCTS
 Industrial crepe, masking, gumming, foil laminating, flame-resistant,
 specialty metal interleaver, cable wrap, creped tape backing,
 electrical insulation, pressure-sensitive backing, water base and film
 coating, ink-jet printing, packaging, saturating, and grease-resistant
 papers.

     PRINCIPAL MARKETS & DISTRIBUTION METHODS
 Sold directly to manufacturers and converters, mainly in the U.S., in
 the following industries:  housing, steel, aluminum and other metal,
 masking tape and masking paper, electrical cable, wire and components,
 automotive, general converters, composite can packaging, filter, and
 specialty coating.

     PRINCIPAL COMPETITION
 Competition in several grades of paper made from the Mosinee mill's
 natural kraft pulp comes from other fully-integrated, large paper
 companies such as Thilmany Paper, Longview Fibre Corporation, and
 Gilman Paper Company.  Competition in grades of paper made from market
 pulp comes from several non-integrated specialty paper mills such as
 Little Rapids Paper Company, as well as large integrated paper
 companies such as Crown Vantage Corporation.

 The Sorg mill produced additional specialty grades of paper, including
 decorative laminate papers, deep color tissue used in napkin and
 tablecloth stock, and colored school construction paper.  Products,
                                     -2-

 markets and distribution methods and principal competitors for the Sorg
 mill during 1999 can be summarized as follows:

     PRINCIPAL PRODUCTS
 Deep-color and white tissue (facial quality, napkin, and tablecloth),
 filter paper (vacuum bag and food cooking), decorative laminates (print
 base, solid color core, alpha overlay, and barrier), report,
 construction, photo background, perforating tape, flame-resistant,
 blotting, soapboard/soapwrap, and saturating papers.

     PRINCIPAL MARKETS & DISTRIBUTION METHODS
 Sold directly to manufacturers and converters with limited marketing
 through paper brokers and distributors mainly in the U.S., in the
 following industries:  housing, consumer product packaging, home
 appliances, filters, printing, advertising and promotion commercial
 goods, soapboard and soapwrap, saturators, specialized industrial
 converters.

     PRINCIPAL COMPETITION
 Both non-integrated specialty mills and larger integrated paper
 companies compete with Sorg products.  Competitors in Sorg's major
 paper grades of decorative, soapboard, saturating base and vacuum bag
 include Crown Vantage Corporation, Mead Corporation, Munksjo, Kimberly
 Clark Corporation, Dexter, Fletcher, Monadnock Paper Mills, Riverside
 Paper Corp., Little Rapids Paper Company, and French Paper Company.

     PRINTING & WRITING GROUP

 The Printing & Writing Group produces and converts two lines of paper
 products in five facilities.

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

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

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

     PRINCIPAL COMPETITION

 Competition in printing and writing grades comes from specialty
 divisions of major integrated paper companies such as International
 Paper Corporation, Georgia-Pacific Corporation, Champion Paper
 Corporation, Fraser Paper, Inc., SAPPI, and smaller privately held
 non-integrated companies.
                                     -3-
 On January 3, 2000, the Company sold the Printing & Writing Group's
 Specialty Products business, although it retained the Appleton,
 Wisconsin, converting facility.  During 1999, the Specialty Products
 facility manufactured school supply papers, craft, and retail products.
 Products were sold in sheet and roll form to stocking distributors
 which serve the 16,000 school districts throughout the United States
 and various retail markets.  The Appleton facility will be reconfigured
 to more specifically support the finishing and distribution needs of
 the Printing & Writing Group to minimize the outsourcing of
 converting requirements for the Brokaw and Groveton mills.  The Group
 will continue to book contract converting volume to utilize any
 remaining capacity.

 The Mosinee Converted Products facilities produce wax-laminated roll
 wrap and related specialty finishing and packaging products such as
 custom coating, laminating and converting wrap.  Converting facilities
 are operating in Columbus, Wisconsin, and Jackson, Mississippi.
 Products, markets and distribution methods and principal competitors
 for Mosinee Converted Products are as follows:

 PRINCIPAL PRODUCTS
 Roll and skid wrap, roll headers, can body stock, cold seal packaging,
 and fabric softener, impregnated, medium, non-woven, and coated papers.

 PRINCIPAL MARKETS & DISTRIBUTION METHODS
 Sold direct to manufacturers and converters in the U.S. in the
 following markets: paper industry, industrial packaging, corrugated
 containers, consumer products, and composite can manufacturers.

 PRINCIPAL COMPETITION
 Competition in roll wrap comes from the other wax and poly laminators
 and includes Laminated Papers, Sonoco Products, Bonar Packaging, Ltd.,
 Fortifiber, Inc., Ludlow, Simplex, and Fiberlam, Inc.

 TOWEL & TISSUE GROUP

 The Towel & Tissue Group produces a complete line of towel and tissue
 products which are marketed along with soap and dispensing system
 products for the industrial and commercial "away-from-home" market.
 Although the Group has grown significantly, it is one of the smaller
 competitors in this market.

 Towel and tissue products made from recycled material and marketed
 under Bay West's EcoSoft<trademark> brand name are used in the
 washrooms of theme parks, hospitals, hotels, office buildings,
 factories, schools, and restaurants nationwide.  The Group's towel and
 tissue mill is located in Middletown, Ohio and its converting facility
 is located in Harrodsburg, Kentucky.  Products, markets and
 distribution methods and principal competitors for the Towel & Tissue

 Group can be summarized as follows:

 PRINCIPAL PRODUCTS
 Washroom roll towels, washroom folded towels, soaps, a variety of towel,
 tissue, and soap dispensers, windshield folded towels, industrial
 wipes, tissue products, dairy towels, household roll towels, and
 premium towel and tissue.
                                     -4-
 PRINCIPAL MARKETS & DISTRIBUTION METHODS
 Sold almost exclusively through sanitary maintenance suppliers and
 paper distributors in the U.S. and several foreign countries for use in
 the following markets:  industrial and commercial washroom, educational
 institutions, health care, dairy, automotive service, and food
 processing industries.

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

     EXPORT SALES

 In addition to the three operating groups, Wausau-Mosinee
 International, Inc. is the commissioned sales agent for the export
 sales of the Company.  Wausau-Mosinee International, Inc. has elected
 to be treated as a FSC for federal income tax purposes.

 RAW MATERIALS

 Pulp is the basic raw material for paper production and represents
 approximately one-half of the cost of making paper.  The Mosinee and
 Brokaw mills produce approximately 85% and 50%, respectively, of their
 own pulp needs.  Timber required for operation of the Company's pulp
 mills is readily available.  The balance of the Company's pulp needs
 (approximately 450,000 tons) is purchased on the open market,
 principally from pulp mills throughout the United States and Canada.
 During 1999, the average cost of pulp rose approximately $150 per ton.
 Pulp prices rose during the first quarter of 2000, and are expected to
 increase further during 2000.  Pulp was readily available in 1999 and
 is expected to continue to be readily available in 2000.  The Company
 has purchased, and may, from time to time in the future, purchase pulp
 futures contracts as a hedge against significant future increases in
 the market price of pulp.

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

 The Towel & Tissue Group produces substantially all of its de-inked
 fiber needs from 100% post-consumer waste which is readily available
 from domestic suppliers.

 Various chemicals are used in the pulping and papermaking processes.

 These industrial chemicals are all available from a number of suppliers
 and are purchased at current market prices.

     ENERGY

 The Company's paper mills require large amounts of electrical and steam
 energy which are adequately supplied by public utilities or generated
 at Company operated facilities.  The Company generates approximately
 25% of its electrical power needs from steam, fuel oil, coal, wood
 chips, fibercake, and natural gas powered generating facilities.  The
 Company generally purchases natural gas, coal, and fuel oil on a
 contract basis at prevailing market prices.  Wood chips and fibercake
 are byproducts of mill operations.  Some natural gas and fuel oil
 purchase contracts may provide for variable prices or contain caps on
                                     -5-
 prices of natural gas to be delivered at future dates.  In addition,
 the Company continues to explore alternative power sources as an
 ongoing business process.

 Under the terms of a long-term agreement with the Portland Natural Gas
 Transmission System the Company is committed to the purchase of a fixed
 volume of natural gas for its Groveton, New Hampshire mill until
 November, 2019.

     PATENTS AND TRADEMARKS

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

     SEASONAL NATURE OF BUSINESS

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

     WORKING CAPITAL

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

     MAJOR CUSTOMERS

 One customer accounted for approximately 9.7% of consolidated net sales

 during 1999.  The loss of this customer would have an adverse
 effect on the Company's business, but the Company believes such effect
 would be of relatively short duration.

     BACKLOG

 The Company's order backlog at December 31, 1999 approximated 34,000
 tons, or 2 weeks of operation.  The backlog on such date was 13% higher
 than December 31, 1998.  Backlog totals do not accurately represent the
 strength of the Company's business activity as a significant volume of
 orders are shipped out of inventory promptly upon order receipt.  This
 portion of the business is not reflected in the Company's backlog
 totals.  The entire backlog at December 31, 1999 is expected to be
 shipped during fiscal 2000.

     RESEARCH AND DEVELOPMENT

 Expenditures for product development were approximately $2,293,000 in
 1999, $2,577,000 in 1998, and $1,577,000 in 1997.
                                     -6-
     ENVIRONMENT

 The Company has a strong commitment to protecting the environment.
 Like its competitors in the paper industry, the Company faces
 increasing capital investments and operating costs to comply with
 expanding and more stringent environmental regulations.  The Company
 estimates that its capital expenditures for environmental purposes will
 approximate $21-$23 million in 2000.

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

 In response to these regulations, the Company has opted to adopt Total
 Chlorine Free (TCF) technology for the pulp bleaching operations at the
 Brokaw mill.  This TCF technology must be in place and functioning by
 April 15, 2001.  In 1988, the Company installed an oxygen
 delignification system which eliminated the use of elemental chlorine;
 however, chlorine compounds are used in other stages of the bleaching
 process at the Brokaw mill.  Compliance with a TCF requirement for the
 Brokaw mill will require an estimated capital expenditure of $7 million.

 The Mosinee facility will be required to burn additional noncondensable
 gases and treat foul condensates to comply with the Cluster Rules.  The
 majority of the required changes must be satisfied by April 15, 2001,
 while compliance with the balance of these new requirements must be
 attained by April 15, 2006.  The estimated capital expenditures to
 comply with the Cluster Rules and, at the same time provide, other
 production efficiencies at the Mosinee facility is $14 million.  The
 capital expenditures for complying with the Cluster Rules will be
 incurred in 1999, 2000, and 2001.  Company-wide capital expenditures
 initiated to comply with the Cluster Rules are estimated to be in the

 range of $20-$22 million.

 Compliance with the EPA's permitting process involves the consolidation
 of all Company air discharge permits and is expected to involve an
 additional $1 million in capital expenditures.  This cost is expected
 to be incurred in 2000 or 2001.  The Wisconsin Paper Council and
 certain Wisconsin utilities successfully challenged the inclusion of
 Wisconsin in the EPA's initiative to reduce boiler emissions.  The
 Wisconsin Department of Natural Resources ("DNR") response to this
 decision has not yet been announced.  If the DNR were to require
 similar boiler emission reductions as those proposed under the EPA's
 proposal, the capital expenditures required for the Rhinelander and
 Mosinee facilities would approximate $3 million.

 In 1986, the Company's Mosinee Paper Corporation subsidiary was
 informed by the DNR that a landfill, for which Mosinee may be a
 potentially responsible party, had been nominated by the DNR for
 inclusion by the EPA on the National Priorities List ("NPL")
 established under the federal Comprehensive Environmental Response,
 Compensation and Liability Act ("CERCLA").  Although the EPA did not
 place the landfill on the NPL and no other action has been taken by the
 DNR or the EPA, the Company and DNR continued to explore ways to
 initiate an investigation outside of the CERCLA Superfund program over
 a period of several years.  In March, 2000, the DNR indicated, after a
 lapse of several years, that it was again going to review the status of
 this landfill and the potential liability of the Company.  The Company
 cannot predict what the cost of investigation and cleanup will be, what
 share, if any, of such costs will be borne by the Company, or the
 extent to which, if any, the Company may have insurance coverage for
 such potential liability.  Based on its previous analysis of this
 matter, the Company does not believe that any associated potential
 costs would have a material adverse effect on the business and
 financial condition of the Company.
                                     -7-
 The Company believes that capital expenditures associated with
 compliance with the Cluster Rules and other environmental regulations
 will not have a material adverse effect on its competitive position,
 consolidated financial condition, liquidity, or results of operation.

     EMPLOYEES

 In 1998, the Company announced a workforce reduction program that
 resulted in the elimination of 400 positions through the end of 1999,
 almost all of which were accomplished through early retirement
 incentives.

 The Company had approximately 3,400 employees at the end of 1999.  The
 closing of the Sorg mill in May, 2000, will reduce the number of
 employees by 200.  Most hourly mill employees are covered under
 collective bargaining agreements.  One new labor agreement between Bay
 West-Middletown and P.A.C.E. Local 112 was negotiated in 1999.  Three
 labor agreements expire in 2000 and an additional agreement in 2001.
 The Company expects that new multi-year contracts will be negotiated at
 competitive rates.  The Company considers its relationship with its
 employees to be good.

 CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

 This report contains forward-looking statements within the meaning of
 the Private Securities Litigation Reform Act of 1995 (the "Reform
 Act").  In addition, certain statements in future filings by the
 Company with the Securities and Exchange Commission, reports to
 shareholders, press releases, and other oral and written statements
 made by or with the approval of the Company which are not statements of
 historical fact will constitute forward-looking statements within the
 meaning of the Act.

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

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

 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:
                                     -9-
 <circle> Increased competition from either domestic or foreign paper
          producers or providers of alternatives to the Company's
          products, including increases in competitive production
          capacity resulting in sales declines from reduced shipment
          volume and /or lower net selling prices in order to maintain
          shipment volume.

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

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

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

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

 * "Practical capacity" is the amount of product a mill can produce with
    existing equipment and workforce and usually approximates maximum,
    or theoretical, capacity.  At the Company's converting operations it
                                     -11-
    reflects the approximate maximum amount of product that can be made
    on existing equipment, but would require additional days and/or
    shifts of operation to achieve.

 The Company owns approximately 123,000 acres of timberland.


 ITEM 3.  LEGAL PROCEEDINGS.

 In 1997, the Attorney General of the State of Florida filed a civil
 complaint in the United States District Court for the Northern District

 of Florida against ten manufacturers of commercial sanitary paper
 products, including the Company's wholly owned subsidiary, Bay West
 Paper Corporation.  The lawsuit alleges a conspiracy to fix prices of
 commercial sanitary paper products starting at least as early as 1993.
 Since the filing of this lawsuit, numerous class action suits have been
 filed by private direct purchasers of commercial sanitary paper
 products in various federal district courts throughout the country and
 additional federal lawsuits have been filed by the Attorneys General of
 the States of Kansas, Maryland, New York, and West Virginia.  All of
 these federal cases have been certified as class actions and
 consolidated in a multi-district litigation proceeding in the United
 States District Court for the Northern District of Florida in
 Gainesville.  Certain indirect purchasers of sanitary commercial paper
 products have also filed class action lawsuits in various state courts
 alleging a conspiracy to fix prices under state antitrust laws.  No
 class has been certified in the state actions. All of these actions
 are in early stages. In the opinion of management, the Company has not
 violated any antitrust laws and these cases are without merit.  The
 Company is vigorously defending these claims.

 Although no proceeding has commenced, the Company may be subject to a
 claim as a potentially responsible party with respect to a Wisconsin
 landfill.  See the discussion of this potential claim under the
 subheading "-- Environment" in Item 1 of this report.

 The Company may also be involved from time to time in various other
 legal and administrative proceedings or subject to various claims in
 the normal course of its business.  Although the ultimate disposition
 of legal proceedings cannot be predicted with certainty, in the opinion
 of management, the ultimate disposition of any threatened or pending
 matters, either individually or on a combined basis, will not have a
 material adverse effect on the consolidated financial condition,
 liquidity, or results of operations of the Company.

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

 No matters were submitted to a vote of shareholders during the fourth
 quarter of 1999.
                                     -12-

 ITEM 5.  MARKET FOR THE REGISTRANT'S COMMON STOCK AND RELATED
          STOCKHOLDER MATTERS.

 Since March 26, 1998, the Company's common stock has been traded on the
 New York Stock Exchange under the symbol "WMO".  Prior to March 26,
 1998, the Company's common stock was traded on the Nasdaq National
 Market under the symbol "WSAU."

 As of the record date of the annual meeting, February 24, 2000, (the
 "Record Date") there were approximately 3,000 holders of record of the
 Company's common stock.  The Company estimates that as of the Record
 Date there were approximately 8,500 additional beneficial owners whose
 shares were held in street name or in other fiduciary capacities.  As
 of the Record Date, there were 51,416,691 shares of common stock

 outstanding.

 The following table sets forth the range of high and low closing price

   *Due to the change in fiscal years from an August 31 year-end to a
    December 31 year-end, no dividend was declared in the first quarter
    of 1998.  Two dividends were declared in the second quarter.

   <dagger>All prices through March 25, 1998 represent closing
           quotations on the Nasdaq National Market and reflect
           inter-dealer prices, without retail markup, mark-down or
           commission and may not necessarily represent actual
           transactions.  Prices after March 25, 1998 represent the
           high and low sales prices on the New York Stock Exchange.

     NET SALES

 (ALL DOLLAR AMOUNTS IN THOUSANDS)           1999                  1998                  1997

 Although net sales were comparable for the twelve months ended December
 31, 1999 and 1998, the tonnage shipped increased in 1999 by 13,000
 tons, or 2%, to a new Company record of 844,800 tons.  Total shipments
 in 1997 were 798,500 tons.  Overall, the selling prices for the
 Company's products began to increase late in 1999 following selling
 price declines in 1997, 1998 and part of 1999.  The selling price
 declines experienced were due to competitive pressure on several
 products in the Company's printing and writing, specialty and towel
 and tissue grades.

 Shipments for the Printing & Writing Group increased to 361,300 tons
 and were 3% higher than 1998 shipments.  The growth in premium paper
 and roll wrap sales was the major reason for the increase.  The total
 tons of product shipped in 1998 and 1997 were comparable.  Selling
 prices began to increase late in 1999 principally to recover rising raw
 material costs.  For 2000, the focus will be on increasing premium
 paper sales.  The increase will be sought through normal distribution
 channels as well as an expansion of the retail business.

 Shipments declined 2% to 359,300 tons for the Specialty Paper Group in
 1999.  The decrease was due to a change in the overall product mix and
 the paper machine rebuild at the Otis facility.  The volume shipped in
 1998 had increased by 7% over 1997.  The main reason for the 1998
 volume increase was the acquisition of the Otis facility in May of
 1997.  Competitive market pressures resulted in lower selling prices on
 a year-over-year comparison until late in 1999 when selling prices
 began to increase.  The increase in selling price was principally the
 result of an attempt to recover rapidly escalating raw material costs.
 The improvement of overall product mix will again be the focus for the
 Specialty Paper Group in the year 2000.  A number of opportunities have
 been identified to improve product mix, including the high performance
 liner (HPL) project which is scheduled to be completed late in the
 third quarter of 2000.

 The Towel & Tissue Group continued the record volume growth experienced
 in the last three years.  Volume has increased 11%, 13% and 14%
 year-over-year in 1999, 1998 and 1997, respectively.  Total shipments
 in 1999 were 124,200 tons.  The major contributors to the record
 increases have been increased distribution and excellent customer
 service.  Selling prices had declined in all three years until very
 late in 1999 when prices increased approximately 3%.  Competitive
                                     -15-
 market pressures experienced in all operating groups during 1999
 resulted in depressed selling prices; however, the paper markets have
 seemed to tighten and further price increases are expected as

 supply/demand economics improve.  Order backlog at the end of 1999
 approximated 34,000 tons for all operating groups and was 13% higher
 than order backlog at the end of 1998.  Backlogs had declined by 10% in
 1998 compared to 1997.  Order backlog total does not necessarily
 indicate the business strength since a substantial percentage of orders
 are shipped directly from inventory upon receipt.

     GROSS PROFIT ON SALES

 Gross profit margins have decreased for the last two years.  This
 decline in margins was principally due to competitive market pressures
 that lowered selling prices.  Margins in 1999 were also negatively
 impacted by rapidly escalating raw material costs.

 Market prices for pulp, the primary raw material used in manufacturing
 paper, rose significantly in 1999.  The average list price of northern
 bleached softwood kraft, a frequently used benchmark pulp grade, rose
 25% in 1999 compared to declines of 20% and 18% for 1998 and 1997,
 respectively.  The Company purchases approximately 450,000 tons of
 pulp annually.

 Wastepaper prices, the primary raw material used in the Towel & Tissue
 Group doubled in 1999 compared to increases of 6% and 10% for 1998 and
 1997, respectively.  The Company purchases approximately 145,000 tons
 of wastepaper annually.  On an annual basis, the 1999 increases in pulp
 and wastepaper costs impact the Company's raw material costs by
 approximately $75 million.

 The Printing & Writing Group's mills operated near capacity for the
 last three years.  Difficulties in Brokaw's pulp mill negatively
 impacted operations and increased costs in 1999 and 1998.  Other
 facilities within the group experienced year-over-year production
 increases for all years presented.  Inventory levels remained
 relatively constant on a year-over-year basis.

 The Specialty Paper Group mills operated near capacity for all years
 presented.  The reduction in produced tonnage at the Otis facility,
 because of its machine rebuild, was offset by gains at the Sorg
 facility, which had rebuilt one of its machines in 1998.  Overall,
 production declined 5% in 1998 compared to 1997 principally due to
 product mix.  This product mix was partially offset by the Otis
 acquisition in May of 1997.  Inventory levels increased approximately
 10% in 1999 and had fallen a similar amount in 1998.  The Towel &
                                     -16-
 Tissue Group's production and inventory levels increased ratably with
 its sales growth for all years presented.

     LABOR

 A new four-year labor agreement with the Paper, Allied-Industrial,

 Chemical & Energy Workers International Union at the Ohio mill was
 successfully negotiated in 1999.  The agreement contained wage
 increases similar to other paper companies.  Labor agreements expire in
 other facilities in 2000, 2001 and 2002.  The Company maintains good
 labor relations in all facilities.

 Selling and administrative expenses were impacted by stock incentive
 programs charges or credits, which were determined by the Company's
 stock price change.  During 1999 and 1998, decreases in the Company's
 stock price resulted in a $3.9 million and $1.8 million credit,
 respectively.  In 1997, the Company's stock price increased and the
 charge for such programs was $2.1 million.

 General inflationary costs offset by fluctuations in incentive
 compensation and retirement plan costs along with the acquisitions of
 the Otis and B&J facilities accounted for a majority of the other
 changes.  In connection with the merger with Mosinee Paper Corporation
 (Mosinee), the Company incurred pre-tax expenses related to the merger
 of $13.5 million, which were charged to operations in 1997.  The costs
 included professional fees and other transaction costs for executing
 the merger as well as the costs of the severance benefits paid to the
 former CEO of the Company.  The merger costs on an after-tax basis were
 $13.2 million or $.23 per share.  Restructuring and further merger
 costs were recorded in 1998 of $42.8 million.  Approximately 95% of
 these costs were associated with the Company's early retirement
 incentives along with voluntary separation arrangements, involuntary
 severance agreements, and training costs for the Company's 1998
 workforce reduction program.  The balance of the restructuring costs
 were for legal, consulting, and other miscellaneous costs.

 Interest expense increased in 1999 due principally to increased debt
 levels associated with stock repurchases along with an increase in
 borrowing rates.  Interest was lower in 1998 due to lower borrowing
 rates and lower average debt levels compared to 1997.  Capitalized

 interest totaled $.6 , $.7 and $.5 million in 1999, 1998 and 1997,
 respectively.  Fluctuations in capitalized interest are primarily
 dependent on varying levels of capital expenditures qualifying under
 the capitalized interest criteria.

 Other income includes interest income of $.2, $.4 and $.1 million in
 1999, 1998 and 1997, respectively.  The difference in other income and
 expense is primarily due to fluctuations in the gain or loss on asset
 sales and disposals.

 The effective tax rates for 1999 and 1998 of 37.6% and 38.0%,
 respectively are indicative of the Company's normalized tax rate.  The
 effective tax rate for 2000 is expected to be in that range.  The tax
 rate for 1997 increased principally due to the $13.5 million charge for
 merger-related expenses, most of which was not tax deductible.

 Cash flow from operations decreased in 1999 compared to 1998
 principally due to decreased cash flow earnings from operations.  In
 addition, the investment in accounts receivable also increased by $7.1
 million in 1999.  Changes in working capital principally accounted for
 the changes in 1998 and 1997.

 Capital expenditures totaled $80.6 million in 1999, compared to $77.0
 million in 1998 and $66.1 million in 1997.

 During 1999, the Printing & Writing Group completed several projects at
 the Groveton mill totaling $2.0 million consisting of paper machine
 upgrades and a retrofit of the #1 boiler to convert to natural gas
 consumption.  The Brokaw mill spent $9.1 million on various projects
 including $1.3 million to complete the pulp mill distributive control
 system begun in 1998 and $7.2 million of a $8.2 million project to
 upgrade the dry end of the machine room for better operating

 efficiencies.

 The Specialty Paper Group completed several major capital projects in
 its pulp and paper mills.  At the Mosinee mill, $3.4 million was spent
 to complete a woodroom modernization project and $2.7 million for a new
 winder on the #4 paper machine.  The Otis mill has spent $15.6 million
 to expand the production capacity of one of its paper machines and $1.3
 million on another paper machine to add significant new manufacturing
 capabilities and give the Specialty Paper Group an improved sales mix.
 During 1999, the Board of Directors approved a $45 million rebuild
 project at the Rhinelander mill on which spending of $4.8 million
 occurred in 1999 with the remaining spending to occur in the year 2000.
 This project, which is scheduled to be completed by late in the third
 quarter of 2000, will enable the Specialty Paper Group to move into new
 high growth market niches.

 To keep pace with increasing sales volume, the Towel & Tissue Group
 spent $4.7 million in 1999 to complete a toweling line and a tissue
 converting line and to begin construction of an additional toweling
 line.

 Other major capital improvement projects, approved by the Board of
 Directors in 1999, include $14.4 million to achieve compliance with the
 1990 Clean Air Act Cluster Rules at the Mosinee mill, $6.8 million at
                                     -19-
 the Brokaw mill for a bleaching system, and $6.0 million for a central
 stock prep and fiber optimization project at the Groveton mill.
 Capital spending for 2000 should be in the range of $90 to $100
 million.  The Company believes the borrowings available under its
 credit agreements and its earnings for 2000 will be sufficient to meet
 its cash flow needs for capital, working capital and investing
 activities in 2000.

 During 1999, the Company entered into two new arrangements which
 substantially changed its debt structure.  A private placement of
 $138.5 million in senior notes was closed and funded in August.  The
 notes mature in 8, 10 and 12 years at $35.0 million, $68.5 million and
 $35.0 million, respectively.  In conjunction with the private
 placement, the Company entered into an interest rate swap arrangement
 that effectively converted $88.5 million of fixed rate obligations with
 a weighted average interest rate of 7.35% to variable rate obligations
 with an average effective interest rate of approximately 6.6% at
 December 31, 1999.  The agreement decreased interest expense by
 $.3 million in 1999.

 In December 1999, the Company entered into a new revolving credit
 facility with four banks for $200 million.  The facility has a
 364-day component for $50 million and $150 million for five years.
 The 364-day component may be converted to a one-year term loan at the
 Company's discretion.

 The Company also maintains a commercial paper placement agreement, with
 one of its four major banks, which provides for the issuance of up to
 $40 million of unsecured debt obligations.  The commercial paper
 placement agreement requires unused credit availability under the
 Company's revolving credit agreement equal to the amount of outstanding
 commercial paper.  On December 31, 1999, the Company had a combined
 total of $140.3 million available for borrowing under its revolving
 credit and commercial paper placement agreements.

 In August 1995, the Company obtained $19 million in industrial
 development bond financing to fund an upgrade of the Brokaw mill
 wastewater treatment plant, the construction of a new landfill and
 several other projects which qualify for this type of financing.  Bond
 proceeds were fully disbursed as of January 1997.  In June 1993, the
                                     -20-
 Company borrowed $30 million through the issuance of notes to
 Prudential Insurance Company of America and its subsidiaries.  As of
 December 31, 1999, the outstanding notes amounted to $3.0 million and
 mature in June of 2000.

 On August 31, 1998, the Company's Board of Directors authorized the
 repurchase of 5,650,000 shares of the Company's common stock.  The
 repurchases may be made from time to time in the open market or through
 privately negotiated transactions.  During 1999, the Company repurchased
 2,206,926 shares at prices ranging from $11.94 to $16.06 per share.
 The Company repurchased 4,285,900 shares of its common stock in 1998
 under the completed 1994 authorization and the 1998 authorization at
 market prices ranging from $12.125 to $18.00.  The Company did not
 repurchase any shares of the Company's stock in 1997.  As of December
 31, 1999 there were 217,974 shares available for purchase under the
 authority granted in 1998.

 During 1999, the Board of Directors declared cash dividends of $.32 per
 share, an increase of 14% from the $.28 per share cash dividend
 declared in 1998.

 YEAR 2000

 The Company's program to address year 2000 issues was intended to
 prevent major interruptions in its business due to problems related to
 the Company's computerized manufacturing, environmental, inventory
 management, shipping, financial and other information systems and the
 operation of critical third party vendors and customers.  As part of
 its program, the Company conducted an assessment of its computerized
 manufacturing and information systems and its third party vendors and
 customers.  Some of the year 2000 issues were addressed in connection
 with the initial stages of the implementation of the Company's
 enterprise resource planning system ("ERP").  The broader, non-year
 2000 aspects of the ERP system will be fully implemented after fiscal
 2000.  The Company did not experience any significant disruption as a

 result of year 2000 problems.  As of February 28, 2000, neither the
 Company nor any of its key vendors or customers have experienced any
 material adverse effects related to year 2000 problems.  Based on its
 experience in the year 2000 transition and its business operations
 through such date, the Company does not expect to encounter any year
 2000 problems that would have a material adverse effect on the results
 of operation, liquidity and financial condition of the Company.  The
 costs of achieving year 2000 readiness were not material.  The cost of
 remediation for key papermaking process controls and equipment
 approximated $2 million.  Internal costs for year 2000 readiness were
 not tracked, but principally related to payroll costs of Company
 personnel.  The implementation of the Company-wide ERP system is
 expected to require a capital investment of approximately $7.0 million.
 Although the ERP implementation timetable was not accelerated to
 address year 2000 issues, those issues were considered in determining
 the overall timetable for its implementation.

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

 The Company does not have a material market risk associated with
 interest rate risk, foreign currency exchange risk, or commodity price
 risk.  The Company conducts U.S. dollar denominated export transactions
 or immediately exchanges all foreign currency attributable to export
 sales for U.S. dollars.

 On August 31, 1999, the Company closed and funded a private placement
 note offering for $138,500,000. The principal amounts, maturities, and
 interest rates on the notes are: (1) $35,000,000, 8 years, 7.20%; (2)
 $68,500,000, 10 years, 7.31%; and (3) $35,000,000, 12 years, 7.43%.
 The Company also entered into an interest rate swap agreement under
 which the interest rate paid by the Company with respect to (1)
 $58,500,000 of the 10-year notes will be the three month LIBOR rate,
 plus .4925% and (2) $30,000,000 of the 12-year notes will be the three
 month LIBOR rate, plus .55%.  The Company believes that the
 interest-rate risk associated with the interest-rate swap agreement is
 not material.

 The Company maintains certain derivative commodity instruments as
 hedges for anticipated transactions.  Such instruments do not have a
 material market risk and no such derivative commodity instrument is
 held for trading.  At December 31, 1999, these instruments consisted of
 various futures contracts for the purchase of natural gas and fuel oil.
 The Company has purchased, and may, from time to time in the future,
 purchase pulp futures contracts as a hedge against pulp price
 increases.  See Notes 1 and 14 of "Notes to Consolidated Financial
 Statements" for additional information relating to the Company's
 derivative commodity instruments.

 ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

 REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

 To the Shareholders and Board of Directors
 Wausau<circle>Mosinee Paper Corporation
 Mosinee, Wisconsin

 We have audited the accompanying consolidated balance sheets of
 Wausau<circle>Mosinee Paper Corporation and Subsidiaries as of December
 31, 1999 and 1998, and the related consolidated statements of income,
 cash flows and stockholders' equity for each of the years in the
 three-year period ended December 31, 1999.  These financial statements
 are the responsibility of the Company's management.  Our responsibility
 is to express an opinion on these financial statements 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
 are free of material misstatement.  An audit includes examining, on a
 test basis, evidence supporting the amounts and disclosures in the
 financial statements.  An audit also includes assessing the accounting
 principles used and significant estimates made by management, as well

 SEE ACCOMPANYING NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

           WAUSAU-MOSINEE PAPER CORPORATION AND SUBSIDIARIES

              NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

 NOTE 1.  SIGNIFICANT ACCOUNTING POLICIES

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

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

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

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

 CASH EQUIVALENTS - The Company defines cash equivalents as highly
 liquid, short-term investments with an original maturity of three
 months or less.

 INVENTORIES - Pulpwood, finished paper products and the majority of raw
 materials are valued at the lower of cost, determined on the last-in,
 first-out (LIFO) method, or market.  All other inventories are valued
 at the lower of average cost or market.  Allocation of the LIFO reserve
 among the components of inventories is impractical.

 PROPERTY, PLANT AND EQUIPMENT - Plant and equipment are stated at cost
 and are depreciated over the estimated useful lives of the assets using
 the straight-line method for financial statement purposes.  Land, water
 power rights, and construction in progress are stated at cost.  The
 cost and related accumulated depreciation of all plant and equipment

 retired or otherwise disposed of are removed from the accounts, and any
 resulting gains or losses are included in the statements of income.

 Buildings are depreciated over a 20 to 45-year period; machinery and
 equipment over a 3 to 20-year period. Maintenance and repair costs are
 charged to expense as incurred.  Renewals and improvements which extend
 the useful lives of the assets are added to the plant and equipment
 accounts.
                                     -28-
 Equipment financed by long-term leases, which in effect are installment
 purchases, have been recorded as assets and the related obligations as
 debt.  Depreciation expense includes amortization on capitalized
 leases.

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

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

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

 FUTURES CONTRACTS - The Company utilizes futures contracts to
 periodically hedge the price risk of anticipated purchases of pulp and
 other commodity products.  Changes in the market value of the futures
 contracts are included as part of the acquisition price of pulp and
 other commodity products and are realized when the finished paper is
 sold and the other commodity products are consumed.  Statement of
 Financial Accounting Standards (SFAS) No. 133, "Accounting for
 Derivative Instruments and Hedging Activities" will be adopted
 by January 1, 2001.  The statement establishes accounting and reporting
 standards for derivatives.  The effect on the Company is not expected
 to be material.

 CHANGES IN ACCOUNTING POLICIES - On January 1, 1998, the Company
 adopted Statements of Financial Accounting Standards (SFAS) No.
 130, "Reporting Comprehensive Income," No. 131, "Disclosures about
 Segments of an Enterprise and Related Information," and No. 132,
 "Employers' Disclosures about Pensions and Other Postretirement
 Benefits."  SFAS No. 130 requires companies to report all changes in
 net assets, such as minimum pension liability adjustments, as a
 component of comprehensive income.  SFAS No. 131 requires certain
 disclosures of the company's segments including general information,
 segment profits and assets, and a reconciliation of segment financial

 condition and results of operations to the corresponding company
 amounts.  SFAS No. 132 revises employers' disclosures about pension and
 other postretirement benefit plans.

 NOTE 2.  MERGERS AND ACQUISITIONS

 On December 17, 1997, the Company completed the Mosinee merger.  The
 merger qualified as a tax-free exchange and was accounted for as a
 pooling of interests.  Wausau issued 1.4 shares of common stock for
 each share of Mosinee outstanding common stock.  A total of 21,281,795
 shares (after adjustment for fractional shares) of the Company's common
 stock was issued as a result of the merger, and Mosinee's outstanding
 stock options were converted into options to purchase approximately
 596,000 common shares. In connection with the merger, the Company
 incurred $13,503,000 ($13,203,000 after taxes, or $ .23 per common
 share) of merger-related costs which were charged to operations during
 the year ended December 31, 1997.
                                     -29-
 The following table presents a reconciliation of net sales and net
 earnings previously reported by the Company to those presented in the
 accompanying consolidated financial statements.

    Combined                                               $ 65,398

 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 year ended December 31,
 1997, as if the acquisition were completed at the beginning of the
 period:


 (ALL DOLLAR AMOUNTS IN THOUSANDS)                   1997
                                                

 Net sales                                         $965,982
 Operating profit                                   124,218
 Net earnings                                        66,673
 Net earnings per share-basic                      $   1.15

 The unaudited pro forma financial information includes certain

 immaterial assumptions or adjustments 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.

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

 NOTE 3.  RESTRUCTURING

 In March 1998, the Company began implementation of a workforce
 reduction program.  The purpose of the program was to reduce the number
 of employees by 400 through early retirement incentives along with
 voluntary separation arrangements, involuntary severance programs and
 process automation.  As a result of the program implementation, the
                                     -30-
 Company recorded a pre-tax restructuring charge of $37.7 million in the
 first quarter of 1998.  The charge was based on estimates of the cost
 of the workforce reduction program, including special termination
 benefits, settlement and curtailment losses related to pension and
 postretirement benefit plans.  In the fourth quarter of 1998, an
 additional pre-tax expense of $5.1 million was recorded to recognize
 adjustments to the previous estimates of the early retirement
 incentives and to recognize additional expenses associated with
 integration costs.

 All of the benefits under the program have been paid or have been
 transferred as obligations of the Company's retirement plans as of
 December 31, 1999.

 NOTE 5.  DEBT

 At December 31, 1998 the Company's short-term notes payable consisted
 of $20,000,000 outstanding under an unsecured debt arrangement with one
 financial institution and $25,466,000 outstanding under two separate
 revolving lines of credit.

 The $20,000,000 unsecured debt arrangement was entered into by the
 Company on September 30, 1994, at an interest rate of 7.83%.  Interest
 was paid monthly and the principal was paid in September 1999.

 During 1998, two banks participating in the revolving credit
 arrangement with the Company provided separate lines of credit.  One
 line of credit provided for borrowing up to $20,000,000.  Specific
 rates and terms of the loans were determined at the time of borrowing.

 At December 31, 1998, there was $17,000,000 borrowed against this line
 of credit at a weighted average interest rate of 5.65%.  The second
 line of credit provided for borrowing up to $60,000,000 at rates and
 terms negotiated at the time of borrowing.  At December 31, 1998, there
 was $22,000,000 borrowed against this line of credit at a weighted
 average interest rate of 5.77%.  As of December 31, 1998, of the total
 borrowings against the lines of credit, $25,466,000 was classified as
 short-term and $13,534,000 was classified as long-term as the Company
 intended and had the ability to refinance the obligations under the
 revolving credit agreement.  Both lines of credit were paid in 1999
 from proceeds of the senior promissory notes.

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

 On December 10, 1999, the Company terminated the existing $105 million
 unsecured revolving credit agreement and entered into a $200 million
 unsecured revolving credit agreement.  The facility is with a
 four-member bank group and provides an unsecured short-term revolving
 credit facility of $50 million and a $150 million multi-year revolving
 credit facility, which matures on December 10, 2004.  The short-term
facility may be extended to the first anniversary date of the specified
 maturity date then in effect for the short-term facility if there are
 no events of default under such facility at the time of the extension
 request. The Company may elect the base for interest from either
 domestic or offshore rates.  In addition, the facility provides for
 competitive bid rates amongst the bank group.  The credit facility
 provides for a facility fee based on quarterly funded
 debt/capitalization ratios.

 Based on funded debt and equity levels at December 31, 1999, the
 short-term facility fee was .15% and the multi-year facility fee was
 .175%.  The weighted average interest rate on borrowings under the
 facility at December 31, 1999 was 6.63%.

 At December 31, 1998, the Company maintained an unsecured revolving
 credit facility of $105 million with four banks.  The agreement was
 terminated on December 10, 1999 and all outstanding borrowings on that
 date were refinanced under the $200 million revolving credit agreement.
 At December 31, 1998, the weighted average interest rate on borrowings
 under the $105 million facility was 5.58%.
                                     -32-

 On August 31, 1999, the Company closed and funded a private placement
 note offering for $138,500,000. The principal amounts, maturities, and
 interest rates on the notes are: (1) $35,000,000, 8 years, 7.20%; (2)
 $68,500,000, 10 years, 7.31%; and (3) $35,000,000, 12 years, 7.43%.
 The Company also entered into an interest rate swap agreement under
 which the interest rate paid by the Company with respect to (1)
 $58,500,000 of the 10-year notes will be the three month LIBOR rate,
 plus .4925% and (2) $30,000,000 of the 12-year notes will be the three
 month LIBOR rate, plus .55%.

 The Company has outstanding $3 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.  At December
 31, 1999, the amount has been classified as long-term as the Company
 intends and has the ability to refinance the obligation under the
 revolving credit agreement.

 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 5.30% at December 31, 1999 and 4.30% at December 31, 1998.  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.

 The senior promissory notes, long-term note and the revolving credit
 facility agreements require the Company to comply with certain
 covenants, one of which requires the Company maintain minimum net
 worth.  At December 31, 1999, $91 million of retained earnings was
 available for payment of cash dividends without violation of the
 minimum net worth covenant related to the senior promissory notes.

 The Company maintains a commercial paper placement agreement with a
 bank to issue up to $40 million of unsecured debt obligations which
 requires unused credit availability under its revolving credit
 agreement equal to the amount of outstanding commercial paper.  At
 December 31, 1999 and December 31, 1998, $9,735,000 and $16,466,000
 were outstanding, respectively.  The weighted average interest rate on
 outstanding commercial paper was 6.2% at December 31, 1999 and 5.6% at
 December 31, 1998.  At December 31, 1999, the amounts have been
 classified as long-term as the Company intends and has the ability to
 refinance the obligations under the revolving credit agreement.

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

 NOTE 8.  RETIREMENT AND OTHER POSTRETIREMENT BENEFIT PLANS

 Substantially all employees are covered under retirement plans.  The
 defined benefit plan covering salaried employees in 1998 was converted
 to a cash balance plan additionally covering non-union employees in
 1999.  This plan is a defined benefits plan that provides benefits
 based on pay and company performance; the plans covering hourly
 employees provide benefits based on years of service and fixed benefit
 amounts for each year of service.  The plans are funded in accordance
 with federal laws and regulations.

 The Company selected measurement dates of plan assets of September 30,
 1999 and 1998.

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

 The following are reconciliations of the projected benefit obligations
 and the value of plan assets for 1999 and 1998:

 The Company also sponsors defined contribution pension plans, several
 of whichprovide for Company contributions based on a percentage of
 employeecontributions.  The cost of such plans totaled $1,060,000 in
 1999, $3,066,000 in 1998 and $3,872,000 in 1997.

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

 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.  Effective January 1, 1999, the
 salaried plan was amended whereby employees not yet 45 years of age are
 no longer eligible for postretirement benefits.  The amendment resulted
 in a curtailment gain in 1999.  The Company funds the benefit costs
 on a current basis.

 accumulated post-retirement benefit obligation was 6%, declining by 1%
 annually for one year to an ultimate rate of 5%.  For 1998, the assumed
 health care cost trend rate used in measuring the accumulated
 postretirement benefit obligation was 7%, declining by 1% annually for
 two years to an ultimate rate of 5%.

 Assumed health care cost trend rates significantly impact reported
 amounts.  The effect of a one-percentage-point change in the assumed
 rates would alter the amounts of the benefit obligation and the sum of
 the service cost and interest cost components of postretirement benefit
 expense as follows for 1999:

 NOTE 9.  INCOME TAXES

 Deferred tax assets and liabilities are determined based on the
 estimated future tax effects of temporary differences between the
 financial statement and tax bases of assets and liabilities, as
 measured by the current enacted tax rates.  Deferred tax expense
 (benefit) is the result of changes in the deferred tax asset and
 liability.
                                     -38-
 The provision for income taxes is comprised of the following:

 A reconciliation between taxes computed at the federal statutory rate
 and the Company's effective tax rate follows:

 At the end of 1999, $23,000,000 of unused state operating loss
 carryovers existed which may be used to offset future state taxable
 income in various amounts through the year 2011.  Because separate
 state tax returns are filed, the Company is not able to offset
 consolidated income with the subsidiaries' losses.  Under the
 provisions of SFAS No. 109, the benefits of state tax losses are
 recognized as a deferred tax asset, subject to appropriate valuation
 allowances.
                                     -39-
 The major temporary differences that give rise to the deferred tax
 assets and liabilities at December 31, 1999 and 1998 are as follows:

 A valuation allowance has been recognized for a subsidiary's state loss
 carry forward and future deductible items as cumulative losses create
 uncertainty about the realization of the tax benefits in future
 years.

 NOTE 10.  STOCK OPTIONS AND APPRECIATION RIGHTS

 The Company maintains various employee stock option plans.  The plans
 specify 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.
                                     -40-

 based method" prescribed under APB No. 25, "Accounting for Stock Issued
 to Employees."  Accordingly, no compensation cost has been recognized
 for the stock option plans.  If compensation cost had been determined
 consistent with the provisions of SFAS No. 123, which prescribes the
 "fair value based method" on the grant date, both basic and diluted
 earnings per share would have been $.78, $.73 and $1.12 for the years
 ended December 31, 1999, 1998, and 1997, respectively.

 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:

 The Company maintains various stock appreciation rights plans that
 entitle certain management employees the right to receive cash equal
 to the sum of the appreciation in the 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 provision (credit) for all stock option discounts, dividend
 equivalents and stock appreciation rights for the years ended December
 31, 1999, 1998 and 1997 was ($3,250,000), ($1,520,000) and $2,140,000,
 respectively.

 NOTE 11.  RESEARCH EXPENSES

 Research expenses charged to operations were $2,293,000 in 1999,
 $2,577,000 in 1998 and $1,577,000 in 1997.
                                     -42-
 NOTE 12.  COMMITMENTS, CONTINGENCIES AND RELATED PARTIES

 In 1997, the Attorney General of the State of Florida filed a civil
 complaint in the United States District Court for the Northern District
 of Florida against ten manufacturers of commercial sanitary paper
 products, including the Company's wholly owned subsidiary, Bay West
 Paper Corporation.  The lawsuit alleges a conspiracy to fix prices of
 commercial sanitary paper products starting at least as early as 1993.
 Since the filing of this lawsuit, numerous class action suits have been
 filed by private direct purchasers of commercial sanitary paper
 products in various district courts throughout the country and
 additional federal lawsuits have been filed by the Attorneys General of
 the States of Kansas, Maryland, New York, and West Virginia.  All of
 these federal cases have been certified as class actions and
 consolidated in a multi-district litigation proceeding in the United
 States District Court for the Northern District of Florida in
 Gainesville.  Certain indirect purchasers of sanitary commercial paper
 products have also filed class action lawsuits in various state courts
 alleging a conspiracy to fix prices under state anti-trust laws.  No
 class has been certified in the state actions.  In the opinion of
 management, the Company has not violated any antitrust laws and
 these cases are without merit.  The Company is vigorously defending
 these claims.

 The Company may also be involved from time to time in various other
 legal and administrative proceedings or be subject to various claims
 in the normal course of its business.  Although the ultimate
 disposition of legal proceedings cannot be predicted with certainty,
 in the opinion of management, the ultimate disposition of any
 threatened or pending matters, either individually or on a combined
 basis, will not have a material adverse effect on the consolidated
 financial condition, liquidity, or results of operations of the
 Company.

 Like its competitors, the Company is subject to extensive regulation by
 various federal, state, provincial, and local agencies concerning
 compliance with environmental control statutes and regulations.  These
 regulations impose limitations, including effluent and emission
 limitations, on the discharge of materials into the environment, as
 well as require the Company to obtain and operate in compliance with
 conditions of permits and other governmental authorizations.  Future
 regulations could materially increase the Company's capital
 requirements and certain operating expenses in future years.

 In 1997, the U.S. Environmental Protection Agency published
 regulations, commonly referred to as the "Cluster Rules," affecting
 pulp and paper industry discharges of wastewater and gaseous emissions.
 These rules require changes in the pulping and bleaching processes
 presently used in some U.S. pulp mills, including some of the Company's
 mills.  Based on its evaluation of the rules, the Company spent
 approximately $1.2 million in 1999 and believes that additional capital
 expenditures of approximately $20 million may be required to comply
 with the Cluster Rules over 2000 and 2001.

 As of December 31, 1999, the Company was committed to spend
 approximately $64 million to complete capital projects which were
 in various stages of completion.

 The Company is a party to a natural gas transportation agreement with
 the Portland Natural Gas Transmission System (PNGTS).  Under the terms
 of the agreement, PNGTS has constructed the necessary gas supply and
 delivery equipment to the Company's Groveton, New Hampshire mill.  The
 Company is committed to the transportation of a fixed volume of natural
 gas until November 2019.

 During 1999, the Company purchased 500,757 shares of its stock for
 $7,901,480 from various retirement plans it maintains.  All purchases
 were made at the market price of the stock as traded on the New York
 Stock Exchange on the date of purchase.
                                     -43-
 NOTE 13.  PREFERRED SHARE PURCHASE RIGHTS PLAN

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

 Until a Right is exercisable, the holder will have no rights as a
 shareholder of the Company.  At any time after any person or group
 becomes an Acquiring Person, and prior to the acquisition by such
 person or group of 50% or more of the outstanding Common Shares, the
 Company may exchange the Rights, other than Rights owned by the
 Acquiring Person, in whole or in part, at an exchange ratio of one
 Common Share per Right (subject to adjustment).  At any time prior to
 any person or group becoming an Acquiring Person, the Board of
 Directors may redeem the Rights in whole, but not in part, at a
 price of $ .01 per Right.  The Rights will expire on October 31, 2008
 unless the expiration date is extended or unless the Rights are
 redeemed or exchanged by the Company prior to expiration.

 NOTE 14.  FUTURES CONTRACTS

 At December 31, 1999, the Company was party to various futures
 contracts for the purchase of natural gas.  The natural gas contracts
 require the Company to purchase 300,000 decatherms of natural gas

 during 2000.  The delivered price of natural gas varies from $3.085 to
 $3.169 per decatherm.  At December 31, 1999, the Company's futures
 contracts have no carrying value.  The fair value of the contracts and
 the total deferred gain or loss on the contracts are immaterial at
 December 31, 1999.

 NOTE 15.  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, interest rate agreement, 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.
                                     -44-
 Interest rate agreement - The Company uses an interest rate swap
 agreement to manage its exposure to interest rate changes.  The
 arrangement is considered a hedge of specific borrowings, and
 differences paid and received under the swap arrangement are recognized
 as adjustments to interest expense.  Under the agreement, the Company
 makes payments to a counter-party, that is a major financial
 institution, at variable rates and in turn receives payments at fixed
 rates.  At December 31, 1999, the Company had outstanding $88.5 million
 of fixed rate obligations with a weighted average interest rate of
 7.35% which were effectively converted to variable rate obligations
 with an average effective interest rate of approximately 6.6%.  The
 agreement decreased interest expense by $.3 million in 1999.

 The Company may be exposed to losses in the event of nonperformance of
 the counter-party but does not anticipate such nonperformance.

 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 commodity products
 futures contracts were estimated using the prices published by NYMEX,
 the contract price and the remaining commodity products to be purchased
 under the contracts.

 NOTE 16.  SEGMENT DATA

 Factors Used to Identify Reportable Segments
 The Company's operations are classified into three principal reportable
 segments, the Specialty Paper Group, the Printing & Writing Group and
 the Towel & Tissue Group, each providing different products.  Separate
 management of each segment is required because each business unit is
 subject to different marketing, production and technology strategies.

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

 Measurement of Segment Profit and Assets
 The Company evaluates performance and allocates resources based on
 operating profit or loss.  The accounting policies of the reportable
 segments are the same as those described in the summary of significant
 accounting policies.
