                         WAUSAU PAPER MILLS COMPANY
                      1991 EMPLOYEE STOCK OPTION PLAN


     Wausau Paper Mills Company, a Wisconsin corporation (the "Company"),
 hereby adopts the Wausau Paper Mills Company 1991 Employee Stock Option
 Plan (the "Plan"), as set forth herein.

     Section 1.  PURPOSE.  The Plan has been adopted for the purpose of
 recognizing and rewarding the job performance of key employees of the
 Company and to enable the Company to attract and retain superior
 management-level employees by increasing the personal interest of all such
 employees in the growth and success of the Company.  It is the express
 intent of the Company that, subject to Section 6(g) hereof, all options
 granted hereunder designated "Incentive Stock Options" shall meet the
 requirements of Section 422 of the Internal Revenue Code of 1986, as
 amended (the "Code"), or any successor section or sections.  It is the
 further intent of the Company that options granted hereunder designated
 "Non-Qualified Stock Options" shall not meet the requirements of Section
 422 of the Code.

     Section 2.  NUMBER OF SHARES AVAILABLE FOR OPTIONS.  The aggregate
 number of shares of common stock, no par value, of the Company (the
 "Shares") which may be issued under options granted pursuant to the Plan
 shall be 250,000.

     Section 3.  ADMINISTRATION OF THE PLAN.

     Section 3.1  GENERAL.  The Plan shall be administered by a committee
 (the "Committee") consisting of at least two members designated by the
 Board of Directors of the Company from among those of its members who are
 not officers or employees of the Company or a parent or subsidiary of the
 Company and who otherwise satisfy the definition of a "Non-Employee
 Director" in Rule 16b-3(b)(3) promulgated under Section 16 of the
 Securities Exchange Act of 1934 (the "Exchange Act").  In the absence of
 specific rules to the contrary, action by the Committee shall require the
 consent of a majority of the members of the Committee, expressed either
 orally at a meeting of the Committee or in writing in the absence of a
 meeting.

     Section 3.2  AUTHORITY OF COMMITTEE.  The Committee shall have full
 and complete authority to grant options to such eligible employees on such
 terms, which need not be the same as to all Optionees, as will, in its
 discretion and subject only to the specific limitations elsewhere
 contained in the Plan, carry out the purpose of the Plan.  The Committee
 shall also have full and complete authority to interpret the Plan and
 adopt rules governing the administration of the Plan.  The Committee's
 decision on any matter with respect to the Plan shall be final.

     Section 3.3  INDEMNIFICATION OF COMMITTEE.  To the extent permitted by
 applicable law, the members of the Committee and each of them shall be
 indemnified and saved harmless by the Company from any liability or claim
 of liability which may arise from the administration of the Plan if the
 acts giving rise to such liability or claim of liability were taken in
 good faith and without negligence.

     Section 4.  ELIGIBLE EMPLOYEES.

     Section 4.1  DEFINITION OF ELIGIBLE EMPLOYEES.  Subject to the
 limitations of Section 4.2, key employees of the Company and its
 subsidiary corporations shall be eligible to participate in the Plan.  For
 purposes of the Plan, the term "key employee" shall include all employees
 of all participating employers employed in management, administrative or
 professional capacities.

     Section 4.2  LIMITATIONS ON ELIGIBILITY.  No person who is serving as
 a member of the Committee shall be eligible to receive an option;
 provided, however, that options outstanding prior to an Optionee's
 becoming a member of the Committee shall remain in effect.

     Section 5.  GRANTING OF OPTIONS.  Subject to the limitations of
 Section 4.2, options to purchase Shares shall be granted to such key
 employees who are eligible to participate in the Plan as the Committee
 may, from time to time and at any time, select.  Membership in a class of
 eligible key employees shall not, without specific Committee action,
 entitle a key employee to receive an option to purchase Shares.  Eligible
 key employees selected by the Committee shall be referred to herein as
 "Optionees."

     Section 6.  TERMS AND CONDITIONS OF THE OPTIONS.

     Section 6.1  WRITTEN INSTRUMENT.  Each option to purchase Shares
 granted under the Plan shall be evidenced by a written option agreement
 signed on behalf of the Company and the optionee which sets forth the name
 of the Optionee, the date granted, the price at which the Shares subject
 to the option may be purchased (the "option price"), whether the option is
 an Incentive Stock Option or a Non-Qualified Stock Option, the number of
 Shares subject to the option and such other terms and conditions
 consistent with the Plan as determined by the Committee.  The Committee
 may at the time of grant or at any time thereafter impose such additional
 terms and conditions on the exercise of such option as it deems necessary
 or desirable for compliance with Section 16 of the Exchange Act and the
 regulations promulgated thereunder.  Such option agreement shall
 incorporate by reference all terms, conditions and limitations set forth
 in the Plan.

     Section 6.2  TERMS AND CONDITIONS OF THE OPTIONS.  In addition to any
 other limitations, terms and conditions specified in the Plan, each option
 granted hereunder shall, as to each Optionee, satisfy the following
 requirements:

          (a)  DATE OF GRANT.  Options must be granted on or before June
     18, 2001.

          (b)  EXPIRATION.  No Incentive Stock Option shall be exercisable
     after the expiration of ten years from the date such option is
     granted.  No Non-Qualified Stock Option shall be exercisable after the
     expiration of twenty years from the date such option is granted.

          (c)  PRICE.  The option price as to any Share subject to an
     Incentive Stock Option will be not less than one hundred percent of
     the fair market value of the Share on the date the option is granted.
     The option price as to any Share subject to a Non-Qualified Stock
     Option will be not less than fifty percent of the fair market value of
     the Share on the date the option is granted.

   For purposes of the Plan, the fair market value of a Share means:

     (i)  The mean between the high and the low prices at which the Shares
          were traded if the Shares were then listed for trading on a
          national or regional securities exchange or were then traded on a
          bona fide over-the-counter market; or

     (ii) If the Shares were not traded on an exchange or a bona fide over-
          the-counter market, a value determined by an appraiser selected
          by the Committee.

     In the event that the date on which the fair market value of a Share
     is to be determined is a date on which there is no trading of the
     Shares on a national or regional securities exchange or on the over-
     the-counter market, such fair market value shall be determined by
     referring to the next preceding business day on which trading occurs.

          (d)  TRANSFERABILITY.

     (i)  No Incentive Stock Option shall be transferable by the Optionee
          otherwise than by will or the laws of descent and distribution
          nor can it be exercised by anyone other than the Optionee during
          the Optionee's lifetime.

     (ii) The Committee may, in its discretion, authorize all or a portion
          of any options to be granted to an Optionee or which were granted
          to any Optionee on or before December 16, 1996 to permit transfer
          by the Optionee to (A) the spouse, children or grandchildren of
          the Optionee ("Immediate Family"), (B) a trust for the exclusive
          benefit of the Optionee or the Optionee's Immediate Family, (C) a
          partnership in which the Optionee or the Optionee's Immediate
          Family are the only partners, or (D) to a former spouse of the
          Optionee pursuant to a domestic relations order within the
          meaning of Rule 16a-12 promulgated under Section 16 of the
          Exchange Act; provided, however, that (X) there may be not
          consideration for any such transfer, (Y) the written option
          agreement required by Section 6.1, or any amendment thereof
          approved by the Committee, must expressly provide for
          transferability of the option evidenced in such agreement in a
          manner consistent with this Section 6.2(d), and (Z) once
          transferred pursuant to the preceding provisions of this Section
          6.2(d)(ii), no subsequent transfer of any options shall be
          permitted except a transfer by will or the laws of descent and
          distribution.  In authorizing all or any portion of an option to
          be transferred, the Committee may impose any conditions on
          exercise, prescribe a holding period for the Shares acquired upon
          such exercise and/or impose any other conditions or limitations
          it deems desirable or necessary in order to carry out the
          purposes and requirements of the Plan.  Following transfer, the
          terms and conditions of the plan and the written option agreement
          relating to such option shall continue to be applicable in all
          respects to the Optionee making such transfer and each
          transferred option shall continue to be subject to the same terms
          and conditions as were applicable immediately prior to transfer
          as if such option had not been transferred, including, but not
          limited to, the terms and conditions with respect to the lapse
          and termination of such option.  For purposes of Section 7, the

          transferee of an option shall be deemed an "Optionee".  Neither
          the Company, the Committee or any Optionee shall have any
          obligation to inform any transferee of the termination or lapse
          of any option for any reason.  Notwithstanding any other
          provision of the plan, (YY) following the termination of
          employment of an Optionee, a transferred Non-Qualified Option
          shall be exercisable by the transferee only to the extent, and
          for the periods specified in Section 6(e) as if such option had
          not been transferred and (ZZ) no Non-Qualified Stock Option
          granted prior to November 1, 1996 may be transferred until such
          option has been held by the Optionee for a period of not less
          than six months after the date on which such option was granted.

          (e)  EMPLOYMENT.  No option shall be exercisable unless the
     Optionee shall have been employed by the Company (or any present or
     future parent or subsidiary of the Company) during the period
     beginning on the date the option is granted and ending on a date
     ninety days before the date of exercise; provided, however, that in
     the event an Optionee dies while in the employ of the Company (or any
     present or future parent or subsidiary of the Company) or within
     ninety days after such employment had terminated, the employment
     period requirement described above shall be deemed to have been
     satisfied.

          (f)  MINIMUM HOLDING PERIOD.  No option granted prior to November
     1, 1996 may be exercised before the date which is six months after the
     date on which such option was granted.  Each option shall contain such
     additional or other restriction or restrictions with respect to the
     stated percentage of Shares covered by such option as to which such
     option may be exercised as the Committee may deem desirable or
     necessary in order to carry out the purposes and requirements of the
     Plan.

          (g)  ADDITIONAL RESTRICTIONS RELATING TO INCENTIVE STOCK OPTIONS.
     To the extent that the aggregate fair market value (determined as of
     the time the option is granted) of the Shares for which Incentive
     Stock Options are exercisable for the first time by an individual
     during any calendar year (under this Plan or any other plan of the
     Company or any of its subsidiaries) exceeds $100,000 (or such other
     individual limit as may be in effect under the Code on the date of
     grant), such options shall not be Incentive Stock Options.  No
     Incentive Stock Option shall be granted to an employee who, at the
     time such option is granted, owns stock possessing more than ten
     percent of the total combined voting power of all classes of stock of
     the Company or any parent or subsidiary of the Company within the
     meaning of Section 422(b)(6) of the Code unless: (i) at the time the
     option is granted, the option price is at least one hundred ten
     percent of the fair market value of the Shares subject to the option,
     and (ii) such option by its terms is not exercisable after the
     expiration of five years from the date such option is granted.

     Section 7.  EXERCISE AND PAYMENT OF OPTION PRICE.

     Section 7.1  EXERCISE OF OPTIONS.  Options shall be exercised as to
 all or a portion of the Shares by written notice to the Company setting
 forth the exact number of Shares as to which the option is being exercised
 and including with such notice payment of the option price (plus required
 tax withholding).  The date of exercise shall be the date such written

 notice and payment have been delivered to the Secretary of the Company
 either in person or by depositing said notice and payment in the United
 States mail, postage pre-paid and addressed to such officer at the
 Company's home office.  Notwithstanding the fact that an option has been
 transferred pursuant to Section 6.2(d)(ii), the grantee of such option
 shall remain liable for any required tax withholding.

     Section 7.2  PAYMENT FOR SHARES.  Payment of the option price (plus
 required tax withholding) may be made by (a) tendering cash (in the form
 of a check or otherwise) in such amount, or (b) tendering Shares with a
 fair market value on the date of exercise equal to such amount, or (c)
 delivering a properly executed exercise notice together with irrevocable
 instructions to a broker to promptly deliver to the Company the sale or
 loan proceeds equal to such amount.  Notwithstanding the fact that an
 option has been transferred pursuant to Section 6.2(d)(ii), the grantee of
 such option shall remain liable for any required tax withholding.

     Section 8.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION.  If any option
 is exercised in whole or in part subsequent to any stock dividend, stock
 split, recapitalization, reorganization, merger or other change in the
 corporate structure of the Company as a result of which (a) shares of any
 class or classes of the Company shall be issued in respect of the Shares
 or (b) the Shares shall be changed into the same or a different number of
 shares of the same or another class or classes of the Company or another
 corporation, the Optionee so exercising the option shall receive, for the
 aggregate option price payable upon such exercise, the aggregate number
 and class or classes of shares equal to the number and class or classes of
 shares such Optionee would have had on the date of actual exercise if the
 Optionee had purchased on the date the option was granted the Shares as to
 which the option is so exercised and the Shares so purchased had not been
 disposed of as of the date of such actual exercise, taking into
 consideration such stock dividend, stock split, recapitalization,
 reorganization, merger or other change in the corporate structure of the
 Company.

     Section 9.  TERMINATION OR LAPSE OF OPTIONS.  Each option shall
 terminate or lapse upon the first to occur of (a) the expiration date set
 forth in the applicable Stock Option Agreement, (b) the applicable date
 set forth in Section 6.2(b), or (c) the date which is ninety days after
 the date on which the Optionee's employment with the Company or any
 present or future parent or subsidiary of the Company terminated;
 provided, however, that in the event of an Optionee's death while in the
 employ of the Company or a parent or subsidiary of the Company or, if the
 Optionee is no longer so employed, in the event of the Optionee's death
 within ninety days after such employment had terminated, an option may be
 exercised, to the extent exercisable by the Optionee immediately prior to
 his death, in whole or in part by the Optionee's estate or his designee by
 will, or, if applicable, the transferee of such option pursuant to Section
 6.2(d)(ii), but only if the date of exercise is on or before the first to
 occur of (i) the expiration date set forth in the applicable Stock Option
 Agreement, (ii) the applicable date set forth in Section 6.2(b), or (iii)
 the date which is twelve months after the date of the Optionee's death.

     Section 10.  AMENDMENT AND TERMINATION OF PLAN.

     Section 10.1  AMENDMENT OF PLAN.  The Board of Directors of the
 Company may amend the Plan from time to time and at any time; provided,
 however, that no amendment shall adversely affect any option which has

 been granted prior to the amendment and no amendment with respect to the
 maximum number of Shares which may be issued pursuant to options or the
 class of eligible employees, or which materially increases benefits
 accruing to Optionees under the Plan (within the meaning of section 162(m)
 of the Code) shall be effective unless approved by a majority of the
 shares entitled to vote at a meeting of shareholders.

     Section 10.2  TERMINATION OF PLAN.  The Plan shall terminate on the
 first to occur of (a) June 18, 2001 or (b) the date specified by the Board
 of Directors of the Company as the effective date of Plan termination;
 provided, however, that the termination of the Plan shall not limit or
 otherwise affect any options outstanding on the date of termination.

     Section 11.  EFFECTIVE DATE.  The Effective Date of the Plan shall be
 June 19, 1991, the date of approval by the Board of Directors of the
 Company; provided, however, that neither the Plan nor grants made under
 the Plan shall be effective unless the adoption of the Plan is approved at
 the annual meeting of the Company's shareholders next following such date
 by the majority of the shares entitled to vote at such meeting.

     Section 12.  INVESTMENT INTENT.  Shares acquired pursuant to the
 exercise of an option, if not registered by the Company under the
 Securities Act of 1933 (the "Act"), will be "restricted" stock which will
 not be freely transferable by the holder after exercise of the option.
 Each participating employee and assignee in interest of the employee
 accordingly represents, as a condition of participation in the Plan, that
 Shares which are unregistered under the Act are being acquired for the
 Optionee's (or his assignee's) own account for investment only and not
 with a view to offer for sale or for sale in connection with the
 distribution or transfer thereof.

     Section 13.  AVAILABILITY OF INFORMATION.  The Company shall furnish
 each Optionee with (a) a copy of the Plan and the Company's most recent
 annual report to its shareholders at the time the option agreement
 provided for in Section 6.1 is executed by the Optionee and (b) a copy of
 each subsequent annual report, on or about the same date as such report
 shall be made available to shareholders of the Company.  The Company will
 furnish, upon written request addressed to the Secretary of the Company,
 but at no charge to the Optionee or any duly authorized representative of
 the Optionee, copies of all reports filed by the Company with the
 Securities and Exchange Commission or the commissioner of securities of
 any state, including, but not limited to, the Company's annual reports on
 Form 10-K, its quarterly reports on Form 10-Q, and its proxy statements.

     Section 14.  CONDITIONS OF EMPLOYMENT.  Participation in or
 eligibility for participation in the Plan shall not confer upon any
 employee the right to be continued as an employee of the Company or any
 present or future parent or subsidiary of the Company and the Company and
 its participating subsidiaries hereby expressly reserve the right to
 terminate the employment of any employee, with or without cause, as if the
 Plan and any options granted pursuant to it were not in effect.

     IN WITNESS WHEREOF, the Company has caused the Plan, as amended
 December 16, 1996, to be executed by its duly authorized officers as of
 the 16th day of December, 1996.
