 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

 Note 1. 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.  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 accounting principles generally accepted in the United
         States.  Refer to notes to the financial statements which appear in
         the Annual Report on Form 10-K for the year ended December 31, 2000,
         for the Company's accounting policies which are pertinent to these
         statements.

         On January 1, 2001, the Company adopted Statement of Financial
         Accounting Standard (SFAS) No. 133, "Accounting for Derivative
         Instruments and Hedging Activities," and SFAS No. 138, "Accounting for
         Certain Derivative Instruments and Certain Hedging Activities."  The
         statements require all derivative instruments to be recognized on the
         balance sheet as either assets or liabilities at fair value.  Changes
                                 -3-
         in the fair value of derivatives are recognized in either current
         earnings or other comprehensive income in the period of the change.
         Because the Company's hedges are effective, the impact of the
         Company's adoption of SFAS No. 133 and 138 is immaterial to the
         Company's financial statements.

 Note 2. The Company recorded a pre-tax restructuring charge of $25.0
         million in the first quarter of 2000 in the Specialty Paper Group
         segment to cover shutdown and asset disposition costs associated with
         the closure of a paper manufacturing facility in Middletown, Ohio and
         a pre-tax charge of $2.7 million for the resignation of the Company's
         president and CEO.

 Note 3. Net income includes expenses, or credits, for stock-based incentive
         plans calculated by using the average price of the Company's stock at
         the close of the reporting period as if all plans had been exercised
         on that day.  For the three months ended March 31, 2001, these plans
         resulted in after-tax expense of $1,747,000 or $0.03 per share,
         compared to after-tax expense of $651,000 or $0.01 per share for the
         same period last year.

 Note 4. Accounts receivable consisted of the following:

 Note 8. Interim Segment Information

 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 and Jay, Maine.
 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 markets 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.

 ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
 RESULTS OF OPERATIONS*

 RESULTS OF OPERATIONS

 NET SALES

 For the three months ended March 31, 2001, net sales for the Company were
 $224.6 million, a decrease of 8% over last year's first quarter net sales
 of $243.6 million.  Total tons shipped were 193,000 tons and decreased by
 7% company-wide over the first quarter of 2000.

 The Specialty Paper Group's net sales decreased 19% in the first quarter
 of 2001 compared to the first quarter of 2000.  Likewise, total tons
 shipped decreased from 93,500 tons to 75,600 tons quarter-over-quarter.  A
 principle component of the decline in 2001 compared to 2000 was the
 closure of the Sorg Paper Company on May 15, 2000.  Adjusting for the
 closure, first quarter 2001 sales declined 7% and tons shipped declined 6%
 from the first quarter of 2000.  These declines are the result of
 competitive market conditions and a general economic slowdown.

 First quarter net sales and shipments in the Printing & Writing Group were
 comparable in 2001 to the first quarter of 2000. Average selling prices
 for the first quarter of 2001 were down approximately 3% from the first
 quarter of 2000 due to mix deterioration.  In late January 2001, the
 printing paper's business announced a price increase of $60 to $80 per ton
 but successful implementation has been limited primarily to the premium
 paper grades.

 Net sales for the first quarter of 2001 increased 8% over the first
 quarter of 2000 for the Towel & Tissue Group.  Shipments increased to
 31,500 tons and represented a new record for first quarter sales.
 Average selling prices also increased by approximately 1% in the
 first quarter of 2001 compared to the first quarter last year.

 GROSS PROFIT

 Gross profit for the three months ended March 31, 2001 was $16.2
 million or 7.2% of net sales, compared to last year's gross profit of
 $28.2 million or 11.6% of net sales. The decline in gross profit
 margin quarter-over-quarter is principally due to increased energy
 costs, product mix changes and market-related downtime.  In total,
 energy costs have increased $7.5 million over the first quarter of
 2000.  Natural gas costs peaked at near $10 per decatherm and have
 since declined to a level of $5 to $6 per decatherm.  Pulp costs in
 the first quarter of 2001 were similar to the first quarter of 2000
 and have declined since year-end, with significant declines occurring
 in March and April of 2001.

 *  Matters discussed in this report with respect to the Company's expectations
 are forward-looking statements that involve risks and uncertainties.  See
 "Information Concerning Forward-Looking Statements."
                                 -7-
 The Specialty Paper Group's gross profit margin decreased from 8.1%
 of net sales in 2000 to 1% this year. Total Group production,
 excluding the first quarter 2000 production of The Sorg Paper Company
 that was closed on May 15, 2000, was 74,000 tons in the first quarter
 of 2001 compared to 84,000 tons in 2000.  Paper mill inventories at
 March 31, 2001, were approximately 36,000 tons and have increased 9%
 over the level at March 31, 2000.  Customer order backlogs declined
 to approximately 13,000 tons at the end of the first quarter of 2001
 compared to 26,000 tons at the end of the first quarter of 2000.  The
 weak backlogs dictated market-related downtime in the first quarter
 at select facilities to control inventory levels.

 The Printing & Writing Group's gross profit for the first quarter of
 2001 was 7.3% of net sales compared to 13.1% of net sales in the same
 period last year.  Total production for the paper mills was down
 2,000 tons or 2% in the first quarter of 2001 compared to last year's
 first quarter.  Inventory levels and customer backlogs have increased
 quarter-over-quarter.

 The gross profit for the Towel & Tissue Group was 20.4% for the three
 months ended March 31, 2001 compared to 18.6% for last year's first
 quarter.  Shipments increased by 8% to an all time first quarter
 record of 31,500 tons.  Results for the Towel & Tissue group continue
 to benefit from declining wastepaper pricing and ongoing operational
 improvement efforts.  Customer order backlogs have improved on a
 quarter-over-quarter basis.

 SELLING AND ADMINISTRATIVE EXPENSES

 Selling and administrative expenses, excluding the first quarter 2000
 restructuring charge discussed below, were $19.3 million in the first
 quarter of 2001, compared to $19.8 million last year. Expense for
 incentive compensation programs based on the market price of the
 Company's stock was $2.8 million in 2001 compared to $1.0 million for
 the same period a year ago.  In addition, an expense of $2.7 million
 was recorded for the first quarter of 2000 for costs associated with
 the resignation of the Company's President and Chief Executive
 Officer.

 RESTRUCTURING CHARGE

 In March of 2000, the Company announced the planned closure of its
 Sorg facility on May 15, 2000.  In accordance with the closure, the
 Company recorded a pre-tax restructuring charge of $25.0 million in
 the first quarter of 2000.  This charge was classified as $24.4
 million in operating expenses and $0.6 million in cost of sales.  The
 closure costs include $3.6 million in hourly and salaried severance
 cost and $21.4 million in related asset write-downs and disposition
 costs.  In the fourth quarter of 2000, the estimate was revised
 resulting in a $2.7 million pre-tax income adjustment.
                                 -8-
 CAPITAL RESOURCES AND LIQUIDITY

 CASH PROVIDED (USED) BY OPERATIONS

 For the three months ended March 31, 2001, cash used by operations
 was $3.5 million compared to $5.1 million in cash provided by
 operations in the first quarter of the last year.  Reduced
 operational earnings offset by the change in the non-cash charges
 accounted for the change in cash flow quarter-over-quarter.

 CAPITAL EXPENDITURES

 Capital expenditures totaled $5.8 million for the first quarter ended
 March 31, 2001, compared to $7.2 million for the same period last
 year.

 During the first three months of 2001, the Rhinelander mill spent
 $2.1 million on the High Performance Liner (HPL) project.

 FINANCING

 Total current and long-term debt increased for the three months ended
 March 31, 2001 to $259.1 million. The increase in total debt from
 December 2000 is due in part to reduced earnings and dividends paid.

 Interest expense was $4.3 million in the first quarter of 2001
 compared to $3.7 million in the same period of 2000.  The increase in
 interest expense is principally the result of higher funded debt
 levels in 2001 compared to 2000.

 In the first quarter of 2001, the Company terminated an interest rate
 swap arrangement on $30 million of the 12 year senior notes and
 realized proceeds of $2.25 million. In addition, the Company entered
 into a $12.5 million revolving note agreement that expires on March
 8, 2002.  This credit facility replaces a portion of the $50 million,
 364-day facility that expired on March 9, 2001.  Later in 2001, the
 Company may replace a part of the remaining expired facility.

 Cash provided by operations and the borrowing capacity are expected
 to meet capital needs and dividends. The company has approximately
 $42.1 million available from existing bank facilities as of March 31,
 2001.

 COMMON STOCK REPURCHASE

 In April, 2000, the Board of Directors increased the number of shares
 covered by its August, 1998 stock repurchase authorization by
 2,571,000 shares.  The total remaining authority is 2,638,674 shares
 as of April 30, 2001.  There were no stock repurchases in the first
 quarter of 2000 or the first quarter of 2001.
                                 -9-
 DIVIDENDS

 A dividend declared in December, 2000, of $.085 per share was paid
 February 15, 2001 to shareholders of record as of February 1, 2001.
 At the April 19, 2001 meeting, the Board of Directors declared a
 quarterly cash dividend of $.085 per share that is payable May 15,
 2001 to shareholders of record as of May 1, 2001.

                    PART II.  OTHER INFORMATION

 ITEM 1.  LEGAL PROCEEDINGS

 THE FOLLOWING RELATES TO CERTAIN OF THE LITIGATION AND POTENTIAL
 CLAIMS DESCRIBED IN THE COMPANY'S ANNUAL REPORT ON FORM 10-K FOR THE
 FISCAL YEAR ENDED DECEMBER 31, 2000.

 An action alleging violation of antitrust laws is pending in
 Tennessee by indirect purchasers of commercial sanitary paper
 products against the Company's subsidiary, Bay West Paper Corporation
 ("Bay West"), and other defendants.  In the opinion of management,
 Bay West has not violated any antitrust laws and the costs of
 disposition of the Tennessee claim will not be material.

 The Company faces potential liability for penalties for failure to
 file notices of reportable events and for certain excise taxes with
 regard to temporary liquidity shortfalls resulting from voluntary
 supplemental early retirement program benefits paid from two
 qualified plans maintained by subsidiaries.  The Pension Benefit
 Guaranty Corporation ("PBGC") has assessed a penalty of $237,100 in
 connection with the Company's failure to file notices of reportable
 events on a timely basis.  The Company also faces the possible
 liability for excise taxes of approximately $1.5 million in
 connection with the temporary liquidity shortfalls.  The PBGC and the
 Internal Revenue Service ("IRS") each have discretion to waive all or
 part of the penalties or taxes.  The Company is seeking a waiver of
 all penalties and taxes and intends to seek reimbursement of any
 amounts it is required to pay.  The Company will appeal the PBGC's
 initial penalty assessment and has requested an extension of the
 appeal period in order to coordinate its appeal with the pending IRS
 determination.
