            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


 1.  The accompanying financial statements, in the opinion of management,
     reflect all adjustments which are normal and recurring in nature and
     which are necessary for a fair statement of the results for the
     periods presented.  Some adjustments involve estimates which may
     require revision in subsequent interim periods or at year-end. In all
     regards, the financial statements have been presented in accordance
     with generally accepted accounting principles.

 2.  Inventories consist of the following:

 3.  Earnings per share of common stock is based on the weighted average
     number of common shares outstanding and gives effect to applicable
     preferred stock dividends.  Sorg Paper Company preferred stock
     dividends in arrears for the nine months ended September 30, 1997 and
     1996 were $51,840.

 4.  Net income includes expenses for incentive compensation plans based
     upon the company's stock price. The company calculates this liability
     using the average price of Mosinee Paper's stock at the close of each
     fiscal quarter as if all earned incentive compensation plans had been
     exercised on that day.  For the three months ended September 30, 1997,
     these plans resulted in an after-tax expense of $2,416,000 or $0.16
     per share, compared to the third quarter of 1996 which produced an
     after-tax expense of $183,000 or  $0.01 per share.  For the year-to-
     date in 1997 these plans resulted in an after-tax expense of
     $2,564,000 or $0.17 per share, compared to an after-tax expense of
     $2,139,000 or $0.14 per share for the same period of 1996.

 5.  Prior year per share data has been restated for a 3 for 2 stock split
     on May 15, 1997.

 6.  Certain legal proceedings are described under Part II, Item 1 of this
     report.

     annual report for the company's accounting policies which are

               AND RESULTS OF OPERATIONS
                 (All $ amounts are in thousands, except per share
                 amounts)

 On August 25, 1997, the company announced a proposed merger with Wausau
 Paper Mills Company.  This report does not reflect any effect of the
 proposed merger with Wausau Paper Mills Company.

 RESULTS OF OPERATIONS

 Quarterly and year-to-date sales increases produced record earnings before
 stock incentive program charges.  For the third quarter, sales of $89,782
 increased 10% over the $81,761 reported for the third quarter last year.
 This sales increase resulted from $9 million in volume increases offset by
 $7 million in price decreases.  Sales for the quarter of B & J Supply,
 acquired April 1, 1997, accounted for the remaining $6 million increase.
 Product sales mix had little effect on the change in sales.  Year-to-date
 sales of $253,293 increased 7% over the $237,130 reported for the same
 nine month period last year.  This increase followed the same trends as
 the quarterly sales increase.  Volume increases of $20 million were offset
 by $14 million of price decreases, with the difference in the total sales
 increase being the additional sales from B & J Supply.  The volume
 increases and pricing decreases were shared equally between the specialty
 paper sales and the towel and tissue sales.

 Cost of sales for the third quarter of $67,073 increased 14% over the
 $58,764 reported for the third quarter of 1996.  As a percent of net
 sales, cost of sales increased to 75% from the year earlier level of 72%
 primarily due to increased costs for pulp and wastepaper.  For the nine
 months year-to-date, cost of sales of $187,542 increased 8% over the
 $173,445 reported for the same period last year. As a percent of net
 sales, cost of sales increased 1% to the current level of 74%.  This is
 mainly due to raw material costs  rising faster than sales price relief.

 Gross profit, reflecting the above, decreased 1% to $22,709 for the third
 quarter from the $22,997 reported for the same period last year. Gross
 profit as a percent of sales for the quarter decreased to 25% compared to
 the 28% for the third quarter last year.  On a year-to-date basis, gross
 profit of $65,751 increased 3% over the $63,685 reported last year.  The
 gross profit margin for 1997 is 26%, down from last year's level of 27%.
 This reduction in margins is due principally to higher raw material costs
 offset by a continued emphasis on cost reduction programs and higher
 operating efficiencies.

 Operating expenses for the third quarter of $10,763 increased 33%, over
 the $8,114 reported for the third quarter last year. Selling expenses
 decreased 3% from the third quarter last year, while administrative
 expenses, excluding the effect of expense for incentive compensation

                                   -5-

 programs based on the market price of the company's stock, declined $821,
 or 18% from the same period last year. For the third quarter this year and
 last year, a rise in stock prices increased the liability for incentive
 compensation programs resulting in an expense of $3,865 in 1997 compared
 to $307 in 1996.  For the nine months year-to-date, incentive compensation
 based on the company's stock price is an expense of $4,174 for 1997
 compared to an expense of $3,588 last year.  For both the quarter and nine
<PAGE>
 month period this year, general inflationary increases in operating
 expenses, along with increases in basic employee compensation and
 retirement expense were offset by a reduction in costs for bonus programs
 and company contributions to 401-K plans, as well as, general cost
 reduction programs in other areas.

 Reflecting the above, income from operations for the third quarter of
 $11,946 decreased $2,937, or 20% from the year earlier level of $14,883.
 Year-to-date income from operations of $40,241 increased 6% over the
 $37,899 reported for the same period last year.  Excluding the effects of
 the incentive compensation based on the company's stock price, income from
 operations for the third quarter 1997 would have been $15,811, or 4% over
 the year earlier level of $15,190, and year-to-date levels would have been
 $44,415 for 1997 and $41,487 for 1996.

 Interest expense decreased 6% for the quarter and 17% year-to-date
 reflecting the decrease in the average principal balance of outstanding
 long-term debt for the nine months of 1997 compared to the same period of
 1996.  See "Liquidity and Capital Resources" below with respect to current
 level indebtedness.  Interest rates in effect remained relatively the same
 when comparing the third quarter and year-to-date of 1997 to the same
 periods of 1996.  Other income and expense of $319 and $143 for the first
 nine months of 1997 and 1996, respectively, is primarily due to gains on
 disposals of assets.

 As a result, income before taxes reached $11,139 for the third quarter of
 1997 compared to $13,899 during the same period in 1996, a decrease of
 20%.  Pretax income for nine months of 1997 was $37,645, or 9% over the
 $34,530 reported last year. The provisions for income taxes of $4,175 and
 $5,620, for the third quarters of 1997 and 1996 and year-to-date
 provisions of $14,525 and $13,950, respectively, are based on an
 effective income tax rate of approximately 38.5% for 1997 and 40.4% for
 1996.

 Reflecting the above, net income for the third quarter 1997 of $6,964, or
 $0.46 per share, declined from the $8,279, or $0.53 per share reported for
 the same period last year.  For the nine months, net income increased 12%
 from the $20,580, or $1.31 per share reported last year, to $23,120, or
 $1.52 for 1997.

 LIQUIDITY AND CAPITAL RESOURCES

 Cash provided by operating activities for the first nine months of 1997 of
 $27,520 decreased nearly $10 million from the $37,315 provided during the
 first nine months of 1996, with improved net income from operating
 activities being offset by lower tax deferrals and an

                                   -6-

 increase in accounts receivable from the increased sales volume.  Cash
 used in investing activities included $25,170 of capital expenditures
 and $6,235 for the acquisition of B & J Supply.  These capital
 expenditures were partially offset by $450 of proceeds from the disposal
 of capital assets.  The primary capital spending during this period was
 $8,109 for towel and tissue equipment at the Bay West Paper converting
 operation for added capacity to keep pace with Bay West's sales volume
 increases.
<PAGE>
 Cash provided by or utilized in financing activities consisted of
 borrowings under credit agreements of $14,503 for the nine months of 1997,
 compared to payments on credit agreements last year of $19,058.  Cash
 dividends were paid to shareholders of $2,941 and $2,385 for the nine
 months of 1997 and 1996, respectively.  The company also utilized $10,927
 of cash to buy back its own stock in 1997.  Cash provided from operations
 and financing activities less amounts utilized in investing activities
 reduced cash by $2,800 from the year-end level of $3,150.

 As of March 31, 1997, the company maintained a credit agreement with one
 bank acting as agent and certain financial institutions as lenders to
 issue up to $65,000 of unsecured borrowing less the amount of commercial
 paper outstanding. This agreement was amended and restated on April 9,
 1997, and expires on April 9, 2002, allowing for unsecured borrowings of
 $90,000.  The company also maintains a loan agreement with another bank
 for $20,000, making the current total amount available for borrowing of
 $110,000. As of September 30, 1997, the company had issued and outstanding
 $24,264 of commercial paper and had other borrowings under the agreements
 of $40,600 for a total debt of $64,864. This leaves approximately $45,000
 currently available to supplement cash provided from operations for use in
 the business which, at the present time, the company believes to be
 adequate for the operation of the business and planned capital
 expenditures.

 Long-term debt as a percent of total capitalization increased to 32.6%
 from the prior year-end level of 28.1%.  Working capital of $40,147
 increased $12,798 from the end of 1996 reflecting a significant increase
 in accounts receivable due to the increased sales volume and increased
 inventories due to various operating needs. The current ratio, reflecting
 this increase, improved to 1.85:1 at September 30, 1997 from the year end
 level of 1.57:1.


                    PART II - OTHER INFORMATION

 ITEM 1.  LEGAL PROCEEDINGS:

 On November 3, 1997, the Ohio Environmental Protection Agency issued a
 draft permit which includes limitations on photoreactive compound
 emissions at the Company's Bay West facility.  The Company believes that
 the proposed limitations are too restrictive and will seek to modify the
 limitations in further permit discussions to be held with the Ohio
 Environmental Protection Agency.

                                   -7-

 On May 13, 1997, the State of Florida filed a civil complaint in the
 Northern District of Florida against ten manufacturers of commercial
 sanitary paper products, including the company's wholly-owned subsidiary,
 Bay West Paper Corporation, alleging a conspiracy to fix prices starting
 at least as early as 1993.  In addition, on May 13, 1997, a private class
 action suit was filed in the Northern District of Florida against the
 same defendants, also alleging a conspiracy to fix prices.  Related class
 action suits have been filed in federal district courts in at least four
 states and in the state courts of California and Tennessee.  The
 defendants have filed a motion in the California and Tennessee state
 court proceedings to remove the cases to federal court.  The defendants
 in the private class action suits have filed a motion to transfer and
 consolidate the suits with the multidistrict litigation panel.  The
<PAGE>
 company intends to vigorously defend these suits.  While the company
 does not believe, based on the information now available, that these
 suits will have a material adverse effect on the operations,
 liquidity or consolidated financial condition of the company, these
 suits are only recently filed and there can be no assurance as to the
 effect of their outcome on the company.

ITEM 5.  OTHER INFORMATION:

 ACQUISITION OF B & J SUPPLY
 On April 1, 1997, the company acquired the business and assets of B & J
 Supply, Inc. of Appleton, Wisconsin, a converter and nationwide supplier
 of school papers, with a net asset purchase of $6.2 million and payment of
 B & J Supply's existing debt of $2 million.

 MOSINEE PAPER CORPORATION - WAUSAU PAPERS MILLS COMPANY MERGER
 On August 24, 1997, the Company, Wausau Paper Mills Company ("Wausau"),
 and WPM Holdings, Inc., a wholly-owned subsidiary of Wausau ("Merger
 Sub"), entered into an Agreement and Plan of Merger (the "Merger
 Agreement") pursuant to which Merger Sub will be merged with and into the
 company (the "Merger") with the company being the surviving corporation.
 Under the terms of the Merger Agreement, which was unanimously approved by
 the Boards of Directors of the company and Wausau, each outstanding share
 of company 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 Wausau, 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.

 Wausau operates paper mills in Wisconsin, New Hampshire and Maine and is a
 leading producer of 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.  These premium
 printing and writing papers serve four major categories: text and cover,
 index and bristol, imaging, and offset.  More than 80% of Wausau's writing
 and printing paper is sold in sheet form to paper distributors, the
 remaining 20% is sold to converters that serve the greeting card and
 announcement industry.  In addition, Wausau is one of the nation's largest
 manufacturers of supercalendered backing papers for pressure-sensitive
 labeling applications.

                                   -8-

 The company also manufactures specialty papers for a broad range of food
 and medical and industrial applications, including protective barrier
 papers for pet food, microwave popcorn and lightweight paper for
 sterilized medical packaging.  Wausau had revenues of $570 million and
 net income of $48.9 million for its fiscal year ended August 31, 1997.
