NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Note 1. The condensed consolidated financial statements include the results of
        Wausau-Mosinee Paper Corporation and our consolidated subsidiaries.
        All significant intercompany transactions have been eliminated.  The
        accompanying condensed 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.  Results for the interim period are not
        necessarily indicative of future results.  In all regards, the
        financial statements have been presented in accordance with accounting
        principles generally accepted in the United States of America.  Refer
        to notes to the financial statements which appear in the Annual Report
        on Form 10-K for the year ended December 31, 2002, for the Company's
        accounting policies which are pertinent to these statements.
                                       3
Note 2. During the second quarter of 2003, the Company's Towel & Tissue Group,
        reached a settlement of all claims of the parties in the patent
        litigation.  As a result of the settlement, the Company recognized $4.2
        million in pre-tax income (reduction of cost of sales) as a fee for
        licensing certain patented dispenser technologies.

Note 3. Effective March 3, 2003, the Company acquired certain assets of a
        laminated papers producer for approximately $8.4 million in cash.  The
        acquisition is being accounted for as a purchase business combination
        and, accordingly, the purchase price has been allocated using the fair
        values of the acquired receivables, inventory, machinery and equipment,
        and identifiable intangible assets.  No goodwill was recorded as a
        result of this acquisition.  The pro forma disclosures required under
        Statement of Financial Accounting Standard (SFAS) No. 141 "Business
        Combinations" have not been presented as the impact of this acquisition
        does not materially impact the results of operations.

Note 4. SFAS No. 143, "Accounting for Asset Retirement Obligations,"
        Establishes accounting and reporting standards associated with the
        retirement of tangible long-lived assets and the associated asset
        retirement costs.  The Company adopted SFAS No. 143 on January 1,
        2003.  There was no significant impact on the financial statements
        as a result of the adoption.

Note 5. Net earnings include provisions, or credits, for stock incentive plans
        calculated by using the average price of the Company's stock at the
        close of each calendar quarter as if all such plans had been exercised
        on that day.  For the three months ended June 30, 2003, the provision
        for incentive plans was $665,000.  For the three months ended June 30,
        2002, the credit for incentive plans was $317,000.  For the six months
        ended June 30, 2003 and 2002, provisions of $414,000 and $216,000,
        respectively, were recognized as stock incentive plan expense.
                                       4
        As permitted under SFAS No. 123, the Company continues to measure
        compensation cost for stock-option plans using the "intrinsic value
        based method" prescribed under APB No. 25, "Accounting for Stock Issued
        to Employees."

       Pro forma net earnings and earnings per share had the Company elected to
       adopt the fair-value based method" of SFAS No. 123, "Accounting for
       Stock-Based Compensation," are as follows:

Note 10.  Interim Segment Information

          FACTORS USED TO IDENTIFY REPORTABLE SEGMENTS
          The Company's operations are classified into three principal
          reportable segments:  the Printing & Writing Group, the Specialty
          Paper 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 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 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
          Specialty Paper Group produces specialty papers at its manufacturing
          facilities in Rhinelander, Wisconsin; Mosinee, Wisconsin; and Jay,
          Maine.  The Towel & Tissue Group produces a complete line of towel
          and tissue products that are marketed along with 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.

RESULTS OF OPERATIONS

Percent increase/(decrease)                     2%       (1%)       4%       (2%)

For the three months ended June 30, 2003, consolidated net sales for the
Company were $242.8 million compared to $237.8 million for the same three month
period in 2002, an increase of 2%.  Company-wide shipments in the second
quarter of 2003 were 211,414 tons, a 1% improvement over the 209,904 tons
shipped in the second quarter of 2002.  Second quarter 2003 average selling
price increased less than 2% as compared to the same period in 2002 with actual
product selling prices improving approximately 1%, or $2.6 million, and product
mix enhancements accounting for the remainder of the average selling price
increase.

For the six months ended June 30, 2003 and 2002, consolidated net sales were
$482.7 million and $463.7 million, respectively, representing a 4% improvement
year-over-year.  Year-to-date shipments at June 30, 2003, improved to 422,170
tons, an increase of 3% over the 409,027 tons reported for the same year-to-
date period of 2002.  During the first six months of 2003, average selling
price improved approximately 1%, with actual product pricing improvements and
product mix enhancements accounting for an equal share of the increase.
Together, product pricing and product mix changes accounted for approximately
$4.6 million of the consolidated net sales improvement.

Second quarter net sales and shipments for the Printing & Writing Group
increased 4% and 5%, respectively in 2003 compared to the second quarter of
2002.  As a group, net sales improved to $99.5 million in 2003 from $95.8
million reported for the same three-month period in 2002.  Shipments grew
quarter-over-quarter from the 86,412 tons in 2002 to 90,672 tons in 2003. The
increase in tons shipped was driven by a 28 percent increase in laminated roll-
wrap volume as a result of the first quarter acquisition of the production
assets and customer base of Laminated Papers, Inc.  Average net selling price
decreased approximately 1% with product mix changes accounting for the decline
as actual product pricing was principally unchanged quarter-over-quarter.
Second quarter consumer product shipments increased 26% compared to last year
and premium paper shipments increased 3%.  Shipments to paper merchants and
converters declined 5% as demand for uncoated free-sheet papers decreased
approximately 2% compared to the same period last year.  The decline in
shipments to paper merchants and converters is due primarily to a reduction in
paper demand of end-use commercial printers. Market conditions remained weak
and pricing competitive as the third quarter began.
                                       9
Printing & Writing Group net sales for the first half of 2003 improved 3% to
$197.8 million compared to $192.1 million in the first half of 2002.  The
increase in net sales was due primarily to increased shipments year-over-year
with 179,403 tons and 173,481 tons shipped in the first six months of 2003 and
2002, respectively.  As in the quarter-over-quarter comparison, the volume

improvement was driven by the increase in laminated roll-wrap and consumer
product shipments period over period.  Average selling price declined less than
1% year-over-year with both real selling prices and product mix marginally
weaker in the first six months of 2003.

Specialty Paper Group net sales improved to $89.7 million for the three months
ended June 30, 2003 compared to $88.8 million in the three months ended June
30, 2002, an increase of 1%. Shipments declined to 82,651 tons in the second
quarter of 2003 compared to 85,741 tons in 2002.  The volume decline of
approximately 4% was due to a reduction in shipments of non-core product and
was more than offset by a 5% improvement in average selling price in the
quarter-over-quarter comparison.  Product selling prices increased
approximately 4%, with product mix enhancements accounting for the balance of
the average selling price improvement.

For the first six months of 2003, Specialty Paper Group net sales were $182.2
million compared to $171.7 million in the same period of 2002, an increase of
6%.  Shipment volume increased 4% in the year-to-date comparison with 170,326
tons shipped in 2003 and 164,426 tons shipped in 2002.  Average selling price
improvement of 2% year-over-year contributed to the net sales gain and was
driven by actual product pricing improvements of 2% with product mix comparable
to prior year.

Net sales for the second quarter of 2003 were comparable to the second quarter
of 2002 at $53.7 million and $53.3 million, respectively, in the Towel & Tissue
Group.  Mix enhancement, offset by a decline in product pricing, resulted in a
1% improvement in average net selling price quarter-over-quarter.  Shipment
volume remained relatively flat with 38,091 tons shipped in the second quarter
of 2003 compared to 37,751 tons shipped in the second quarter of 2002.  The
"away-from-home" segment of the towel and tissue market grew approximately 1%
in the second quarter of 2003 compared with the same period in 2002.

Year-to-date sales for the Towel & Tissue Group were $102.7 million in 2003
compared to $100.0 million in 2002-an improvement of 3%.  Mix enhancement
resulted in an increase in average selling price of slightly less 2% when
comparing the first half of 2003 to 2002.  The remainder of the year-to-date
revenue gain was the result of a 2% increase in shipment volume with 72,441
tons shipped in 2003 versus 71,120 tons shipped in 2002.

Gross profit for the three months ended June 30, 2003, was $25.1 million
compared to $28.5 million for the three months ended June 30, 2002.  The
decrease in the gross profit margin year-over-year was principally due to
increases in energy and fiber prices.  These increases were partially offset by
volume gains, operational efficiencies and cost-reduction efforts.  In total,
natural gas prices increased 80% resulting in additional cost of $4.3 million
in the second quarter of 2003 compared to the second quarter of 2002. Compared

to the second quarter of 2002, market pulp prices were higher by $90 per air-
dried metric ton, or approximately $9.4 million, quarter-over-quarter while
wastepaper prices were higher by $6 per standard ton, or approximately $0.3
million. During the second quarter of 2003, as the result of a settlement of
all claims of the parties in a patent litigation case, the Company recognized
$4.2 million of income as a fee for licensing certain patented dispenser
technologies.  In addition, the Company recorded $1.9 million during the second
quarter of 2003 for the loss on the disposal of equipment.

Year-to-date, gross profit margins declined to $46.0 million, or 10% of net
sales in 2003 compared to $53.8 million, or 12% of net sales in 2002.  As in
the quarterly comparison, unfavorable market pulp, wastepaper, energy costs and
the expense associated with the disposal of equipment negatively impacted the
gross profit margin year-over-year.  Offsetting a portion of these unfavorable
variances was the settlement of litigation involving patented dispenser
technologies, cost-reduction efforts and improved operating efficiencies. Year-
over- year, market pulp increased 16%, or $63 per air-dried metric ton and
natural gas costs increased 91%.

Early in the third quarter, market pulp list prices declined $30 per air-dried
metric ton while natural gas prices continued to decline from peak first
quarter levels but remained above historical averages.  At the end of the
second quarter, less than half of the Company's July through December natural
gas requirements were protected through purchase contracts. The price of these
contracts is approximately 5% below the Company's second quarter average price.

The Printing & Writing Group's gross profit for the second quarter of 2003 was
8% of net sales compared to 17% for the same period last year.  On a year-to-
date basis, gross profit declined from 15% in the first six months of 2002 to
8% in the first six months of 2003. The decline in gross margins on a quarter-
over-quarter and year-to-date basis is attributable to unfavorable pricing in
both natural gas and market pulp as discussed in the consolidated gross margin
comparisons.

The Specialty Paper Group's improved operations and cost-reduction efforts
offset the unfavorable impacts of natural gas and market pulp to report
improved year-over-year margins from 2% in the second quarter of 2002 to 5% in
the second quarter of 2003.  Similarly, year-to-date margins improved to 6%
from 3% in 2003 and 2002, respectively.
                                       11
The gross profit margin for the Towel & Tissue Group improved from 19% in the
second quarter of 2002 to 24% in the second quarter of 2003.  As indicated in
the consolidated gross profit margin comparisons, a favorable $4.2 million
settlement of patent litigation reduced by unfavorable wastepaper pricing and
expense as the result of asset disposals accounted for the change in the gross
profit margin for the Towel & Tissue Group.  Year-to-date gross margins
remained flat at 20% of net sales in both six month periods ending June 30,
2003 and 2002.

Consolidated order backlogs declined to approximately 30,700 tons at June 30,
2003 from approximately 37,300 tons at June 30, 2002.  Backlog tons at June 30,
2003 represent $34.7 million in sales compared to $39.8 million in sales at
June 30, 2002. Declines in customer backlog were evident in both the Printing &
Writing and Specialty Paper Groups, while the Towel & Tissue Group improved
slightly.  The Printing & Writing Group backlog tons declined from 10,000 tons

as of June 30, 2002 to 7,100 tons at June 30, 2003.  Specialty Paper Group
backlog tons declined to 21,700 tons at the end of the second quarter of 2003
compared to 25,500 tons at the end of the second quarter of 2002.  The Towel &
Tissue Group experienced a slight increase in backlogs compared to the second
quarter of 2002 at 1,900 tons compared to 1,800 tons. The change in customer
order backlogs does not necessarily indicate business conditions as a large
portion of orders are shipped directly from inventory upon receipt and do not
impact backlog numbers.

Selling and administrative expenses in the second quarter of 2003 were $17.4
million compared to $16.7 million in the same period of 2002. Incentive
compensation programs based on the market price of the Company's stock resulted
in a provision of $0.7 million for the three months ended June 30, 2003
compared to a credit of $0.3 million for the three months ended June 30, 2002.

For the six months ended June 30, 2003, selling and administrative expenses
were $33.7 million compared to $33.8 million in the first half of 2002.
Expense recognized for stock-incentive based programs was $0.4 million and $0.2
million in the year-to-date comparisons of 2003 and 2002, respectively.

Other income (expense)                        15        41         1      (14)

Interest expense was $2.6 million in the second quarter of 2003 compared to
$2.8 million in the second quarter of 2002.  The decrease quarter-over-quarter
was attributable to lower average debt levels partially offset by a slightly
higher effective interest rate.  Long-term debt was $162.6 million and $185.8
million at June 30, 2003 and 2002, respectively.  Long-term debt at December
31, 2002, was $162.8 million.  Interest expense is expected to remain slightly
lower in 2003 than in 2002 due to reduced borrowings against the Company's
credit facilities.

LIQUIDITY AND CAPITAL RESOURCES

Cash Flows and Capital Expenditures

                                                    Six Months Ended June 30,
(Dollars in thousands)                                 2003        2002
                                                           
Cash provided by operating activities                $27,965     $26,883
Capital expenditures                                   9,975      10,429

For the six months ended June 30, 2003, cash provided by operating activities
was $28.0 million and improved from the cash provided by operations for the six
months ended June 30, 2002, of $26.9 million.  The improvement in cash flows
provided by operating activities quarter-over-quarter is attributable to $9.0
million in refunds received in the first six months of 2003 on income taxes,
offset somewhat by reduced earnings and larger inventory and receivable
increases in the current year period.

In 2003, due to weak economic conditions and to excess production capacity in
the paper industry, the Company has continued efforts initiated in 2001 to
limit capital spending without sacrificing the maintenance of its facilities
and operating assets. The Company has established an objective to achieve a
weighted-average internal rate of return of 17% on capital projects
                                       13
approved in 2003 and has achieved this objective for projects approved through
the first half of the year. As a result, capital spending for the first six
months of 2003 was $10.0 million compared to $10.4 million during the first six
months of 2002. Capital spending over the second-half of 2003 is expected to be
greater than the first-half of 2003 due to capital projects slated for
installation during the last six months.  Total capital spending in 2003 is
expected to be approximately $30 million, or one-half the Company's rate of
depreciation, depletion, and amortization.

For 2003, capital expenditures for projects with total spending expected to
exceed $1.0 million were $0.6 million in the Printing & Writing Group as part
of a capital project to expand premium papers production capabilities at the
Brokaw mill and $0.4 million on a process control system computer replacement
at the Groveton mill.  In the Towel & Tissue Group, $0.9 million was spent on a
screw press project and $1.1 million was spent for various converting lines.

The balance of spending for the first six months of 2003 was related to

projects that individually are expected to cost less than $1.0 million.  These
expenditures included approximately $4.2 million for essential non or low-
return projects, and approximately $2.8 million on projects expected to provide
a return on investment that exceeds the Company's cost of capital.

Through the end of the second quarter of 2002, capital expenditures for
projects with total spending expected to exceed $1.0 million were $0.8 million
for a pulp mill digester replacement and $0.7 million for a paper machine
process control system replacement at the Printing & Writing Group's Brokaw and
Groveton mills, respectively.  At the Towel & Tissue Group, $2.5 million was
spent on various converting lines.  The balance of the spending in the first
six months of 2002 was on projects individually under $1.0 million.

Effective March 3, 2003, the Company acquired certain assets of a laminated
papers producer for approximately $8.4 million in cash.  The acquisition is
being accounted for as a purchase business combination and, accordingly, the
purchase price has been allocated using the fair values of the acquired
receivables, inventory, machinery and equipment, and identifiable intangible
assets.  No goodwill was recorded as a result of this acquisition.

Long-term debt/capitalization ratio                     32%            31%

As of June 30, 2003, there was no significant change in total debt as compared
to December 31, 2002.

During the second quarter of 2003, the Company entered into a capital lease for
new information systems equipment.  As a result, a capital lease obligation in
the amount of $0.3 million was recorded.

On June 30, 2003, the Company had approximately $131.0 million available
borrowing capacity from existing bank facilities.  The Company's borrowing
capacity and cash provided by operations are expected to meet capital and
dividend requirements.

Dividends

A dividend declared on December 12, 2002 of $0.085 per common share was paid on
February 17, 2003 to shareholders of record on February 1, 2003.  At the April
17, 2003 meeting of the Board of Directors, a quarterly cash dividend was
declared in the amount of $0.085 per common share.  The dividend was paid on
May 15, 2003 to shareholders of record on May 1, 2003. On June 20, 2003, the
Board of Directors declared a quarterly cash dividend of $0.085 per common
share which is payable on August 15, 2003 to shareholders of record on August
1, 2003.
