Badger Paper Mills, Inc.

We have audited the accompanying statements of net assets available for benefits
of Badger Paper Mills, Inc. Profit Sharing Plan and Trust for Union Employees as
of December 31, 2002 and 2001, and the related statements of changes in net
assets available for benefits for the years then ended. These financial
statements are the responsibility of the Plan's management. Our responsibility
is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audits 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 as evaluating the overall
financial statement presentation. We believe our audits provide a reasonable
basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of Badger Paper
Mills, Inc. Profit Sharing Plan and Trust for Union Employees as of December 31,
2002 and 2001, and the changes in net assets available for benefits for the

NOTE A - PLAN DESCRIPTION

     The following brief description of Badger Paper Mills, Inc. Profit Sharing
     Plan and Trust for Union Employees (the "Plan") is provided for general
     information purposes only. Participants should refer to the Plan agreement
     for more complete information.

     1. General

     The Plan is a defined contribution plan that covers substantially all union
     employees of Badger Paper Mills, Inc. (the "Company") that have attained
     the age of 18. Employees who have completed at least two months of service
     with the Company are eligible to make 401(K) contributions. Employees are
     eligible to receive an allocation of the Company's contribution after at
     least 1,000 hours of service during the year and they must be employed at
     year-end. It is subject to the provisions of the Employee Retirement Income
     Security Act of 1974 (ERISA) and subsequent legislation.

     2. Contributions

     The Company contributes to the Plan each year using the sum of two
     calculations. In the first calculation, the Company contributes the greater
     of (1) 25% of its adjusted net income, as defined in the Plan, for the year
     or (2) 4% of the total compensation paid to Plan participants during the
     year plus 4% of the excess compensation as defined in the plan. In the
     second calculation, the Company contributes to the Plan an additional
     contribution of one percent bonus for each three percent EBIT the Company
     earns, up to a maximum contribution of 6% at 15% EBIT. The percent EBIT is
     calculated by dividing the earnings before interest and taxes by net sales.
     The maximum contribution to the profit sharing accounts on a yearly basis
     is 10% in total.

     A cash or deferred arrangement plan, known as CODA, as authorized by
     Section 401(k) of the Internal Revenue Code (IRC), allows employees to
     defer a portion of their compensation up to the applicable IRC limits by
     having it contributed by the Company to their individual account in the
     Plan.

     3. Vesting

     Participants are at all times fully vested in the value of their accounts
     attributable to their voluntary contributions.

     Effective January 1, 2002, vesting in the Company's profit sharing
     contribution is in accordance with the following graduated vesting
     schedule:

               Years of service                 Nonforfeitable percentage
               ----------------                 -------------------------

                  Less than 1                                0%
                  1                                         33
                  2                                         66
                  3 or more                                100


     In 2001, participants became 20% vested in the Company's profit sharing
     contribution following three years of service and were additionally vested
     at 20% for each year of additional service up to seven years of service, at
     which time participants were fully vested.

     Upon death, disability or retirement, participants are automatically 100%
     vested regardless of years of service.

     4. Participant Accounts

     Each participant's account is credited with the participant's contribution,
     an allocation of the Company's profit sharing contribution, Plan earnings
     and forfeitures of terminated participants' nonvested accounts. The
     participants share in the Company's contributions and forfeitures on the
     basis of allocated shares. Shares are determined through a formula based
     upon each participant's earnings and number of years of service with the
     Company.

     5. Investment Options

     Upon enrollment in the Plan, a participant may direct investments
     consisting of his or her employee contributions and employer contributions
     plus actual earnings thereon in 1% increments in any of the investment
     options offered by the Plan.

     Participants may change their investment options daily.

     6. Benefits

     On termination of service due to death, disability or retirement, the
     participant or beneficiary is entitled to receive the full value of the
     participant's account. Upon a participant's termination from employment
     with the Company for a reason other than death, disability or retirement,
     the participant is entitled to the vested balance in their account.

     The method of distribution for account balances exceeding $5,000 will be
     determined by an election made by the Plan participant. The methods
     available are lump sum, direct rollover, installment payments or part
     installments and lump sum. The standard method for account balances less
     than $5,000 is lump sum payments.


NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The financial statements of the Plan have been prepared in conformity with
     accounting principles generally accepted in the United States of America as
     applied to profit sharing plans.

     A summary of the significant accounting policies consistently applied in
     the preparation of the accompanying financial statements follows.

     1. Use of Estimates

     In preparation of the financial statements in conformity with accounting
     principles generally accepted in the United States of America, management
     is required to make estimates and assumptions that affect the reported
     amounts of assets and liabilities, the disclosure of contingent assets and
     liabilities at the date of the financial statements and the reported
     amounts of revenues and expenses during the reported period. Actual results
     could differ from those estimates.

     2. Basis of Accounting

     The financial statements of the Plan are prepared on an accrual basis.

     3. Valuation of Investments

     The Plan's investments are held by Wells Fargo Bank Minnesota, N.A. (the
     "Trustee"). Plan investments are stated at market value as reported by the
     Plan Trustee.

     Investments in securities traded on a national securities exchange are
     valued at the last reported sales price on the last business day of the
     year; securities traded in the over-the-counter market and listed
     securities for which no sale was reported on that date are valued at the
     mean between the last reported bid and asked prices. Investments in mutual
     funds are stated at a value based upon the per unit allocation of the
     funds' net assets, stated at fair market value on the last business day of
     the year.

     4. Net Appreciation/(Depreciation) in Fair Value of Investments

     Net realized and unrealized appreciation (depreciation) is recorded in the
     accompanying statement of changes in net assets available for benefits as
     net depreciation in fair value of investments.

     5. Payment of Benefits

     Benefits are recorded when paid.

                    NOTES TO FINANCIAL STATEMENTS - CONTINUED

                           December 31, 2002 and 2001


NOTE C - INVESTMENTS - Continued

     In general, the investments provided by the Plan are exposed to various
     risks, such as interest rate, credit and overall market volatility risks.
     Due to the level of risk associated with certain investment securities, it
     is reasonably possible that changes in the values of investment securities
     will occur in the near term and that such changes could materially affect
     the amounts reported in the statement of net assets available for benefits.


NOTE D - ADMINISTRATIVE EXPENSES

     All administrative expenses in connection with the operation of the Plan
     are paid from Plan earnings.


NOTE E - PLAN TERMINATION

     Although it has not expressed any intent to do so, the Company has the
     right under the Plan to discontinue its contributions at any time and to
     terminate the Plan subject to the provisions of ERISA. Participants will
     become fully vested upon termination of the Plan.


NOTE F - INCOME TAX STATUS

     The Plan obtained its latest determination letter on February 25, 1999, in
     which the Internal Revenue Service stated that the Plan was designed in
     accordance with applicable requirements of the IRC. Since receiving the
     determination letter, the Plan has been amended. However, the plan
     administrator and the Plan's tax counsel believe that the amended Plan is
     designed and is currently being operated in compliance with the applicable
     requirements of the IRC.


NOTE G - RELATED-PARTY TRANSACTIONS

     Certain plan investments are managed by Wells Fargo Bank. Wells Fargo Bank
     is the trustee as defined by the Plan and, therefore, these transactions
     qualify as party-in-interest transactions.
