MOSINEE PAPER CORPORATION
                 1985 EXECUTIVE STOCK OPTION PLAN

                     As amended March 4, 1999

                       MOSINEE PAPER CORPORATION
                   1985 EXECUTIVE STOCK OPTION PLAN

          1.   PURPOSE.  The Mosinee Paper Corporation 1985 Executive
 Stock Option Plan (the "Plan") is intended to attract and retain key
 executive employees by permitting such employees of Mosinee Paper
 Corporation (the "Company") or any parent or subsidiary of the Company
 to acquire authorized and unissued, or reacquired, shares of common
 stock, $2.50 par value, of the Company ("Stock") pursuant to purchase
 options.  The availability of the options and grants thereof will
 furnish additional inducements to such employees to continue employment
 with the Company, or any parent or subsidiary of the Company, and
 encourage them, by giving them an opportunity to acquire a greater
 stake in the Company's success, to increase their efforts to promote
 the best interests of the Company and its stockholders.  Subject to the
 provisions of the Plan, there may be granted options containing such
 terms and conditions as shall be requisite to constitute them
 "nonqualified stock options," i.e., options which are not "incentive
 stock options" within the meaning of Section 422A of the Internal
 Revenue Code of 1954, as amended (the "Code").  A key employee may be
 granted and may hold one or more nonqualified stock options under this
 Plan.

          2.   ELIGIBLE EMPLOYEES.  The persons eligible to receive
 options under the Plan shall be key executive employees (who may also
 be officers or directors) of the Company or any parent or subsidiary of
 the Company and who are selected by the Executive Compensation & Bonus

                                     -1-

 Committee (the"Committee") designated by the Board of Directors of the
 Company (the "Board").  Directors of the Company or any parent or
 subsidiary of the Company who are not also employees of the Company
 or any parent or subsidiary of the Company shall not be eligible to
 receive options under the Plan.

     3.   TIME AND MANNER OF GRANTING OPTIONS.  From and after the
 Effective Date of the Plan (as defined in Section 16 hereof) and
 continuing to the close of business on the tenth anniversary of such
 Effective Date, the Committee may, at such time or times as the
 Committee may determine, grant to any one or more eligible employees
 ("Optionees") nonqualified stock options, each such option to cover the
 purchase of such number of shares of Stock upon such terms and
 conditions not inconsistent with the Plan as the Committee shall from
 time to time determine.

          No person shall have any right to an option or any other right
 under the Plan unless and until an option shall be granted to such
 person by the Committee.  Subject to the provisions of Section 9
 hereof, no more than 90,000 shares of Stock shall be sold pursuant to
 the exercise of all options granted hereunder.  Any shares for which an
 option is granted hereunder which for any reason are released from such
 option by expiration or termination thereof or otherwise shall be
 available for reoptioning under this Plan.  The Company shall,
 forthwith upon the granting of an option, mail or deliver to the
 Optionee a copy of the Plan and an option certificate evidencing such
 option.  Option certificates shall be in such

                                     -2-

 form and shall contain such terms and provisions not inconsistent with
 the Plan as the Committee shall deem appropriate.

          4.   TERM OF OPTIONS.  In no event shall any stock option
 granted under the Plan be exercisable after the expiration of twenty
 years from the date such option is granted.

          5.   TERMS AND CONDITIONS.

          (a)  Nonqualified stock options granted under this Plan
 shall contain such provisions, not inconsistent with this Plan, as
 may be deemed advisable by the Committee.

          (b)  The option price per share of Stock under any
 nonqualified stock option granted hereunder shall be not less than one
 hundred per cent (100%) of the fair market value of one share of Stock
 on the date such option is granted.

          6.   MANNER OF EXERCISE OF OPTIONS.

          (a)  Subject to the provisions of Section 8 hereof, each
 option granted hereunder shall become exercisable on the date specified
 in the option agreement but in no event earlier than six months after
 the date of grant.  Any shares with respect to which an option becomes
 exercisable shall remain available for purchase by exercise of the
 option in accordance with its terms at any time or from time to time
 before the option expires.

          (b)  Exercise shall be effected only by delivery to the
 Company of an irrevocable written notice of the Optionee's election
 to exercise the option with respect to a specified whole number of
 shares of Stock. Such exercise must be followed within five (5)

                                     -3-

 business days by payment in cash to the Company of (i) the amount of
 the option purchase price for the number of shares of Stock as to which
 the option is then being exercised and (ii) the amount of any
 applicable federal or state withholding taxes.  The Optionee's failure
 to so pay shall result in the forfeiture of his rights under the Plan
 for the number of shares specified in the notice.  No option may be
 exercised with respect to a fractional share of Stock.

          7.   NON-TRANSFERABILITY.  Options granted hereunder shall not
 be transferable by an Optionee otherwise than by will or the laws of
 descent and distribution and may, during the lifetime of an Optionee,
 be exercised only by such Optionee.

          8.   EXERCISE AFTER TERMINATION OF EMPLOYMENT.

          (a)  For purposes of the Plan and each option granted under
 the Plan, an Optionee's employment shall be deemed to have terminated
 at the close of business on the day preceding the first date on which
 he is no longer for any reason whatsoever employed by the Company or
 by any parent or subsidiary of the Company, provided that the Committee
 may determine in one or more particular cases that a leave of absence
 granted by the employing corporation shall not result in the
 termination of an Optionee's employment.

          (b)  If an Optionee's employment is terminated by his
 voluntary resignation or if he is discharged for cause, any option held
 by the Optionee shall expire on the date of such termination.  For
 purposes of this section, "for cause" shall mean affirmative acts in

                                     -4-

 violation of federal, state, or local criminal law.

          (c)  If an Optionee dies while such Optionee is an employee of
 the Company or any parent or subsidiary of the Company or within three
 months after his termination of employment for a reason other than
 voluntary resignation or discharge for cause, any option held by such
 Optionee at the date of the Optionee's death may be exercised by such
 Optionee's estate or the person to whom such option is transferred by
 will or the applicable laws of descent and distribution with respect to
 all or any part of that number of shares of Stock as to which such
 option was exercisable by the Optionee immediately before his death but
 only if the date of exercise is both within 20 years from the Date of
 Grant (or such shorter period in which the option would have expired if
 the Optionee had lived and remained in the Company's employ) and within
 one year after the date of the Optionee's death.  In the event an
 Optionee has attained his Retirement Date (as defined herein), (i) the
 provisions of Section 8(b) and of the preceding sentence shall not be
 applicable to such Optionee's nonqualified stock options and (ii) any
 nonqualified stock option held by such Optionee at the date of the

 Optionee's death may be exercised by such Optionee's estate or the
 person to whom such option is transferred by will or the applicable
 laws of descent and distribution with respect to all or any part of
 that number of shares of Stock as to which such option was exercisable
 by the Optionee immediately before his death but only if the

                                     -5-

 date of exercise is both within 20 years from the Date of Grant (or
 such shorter period in which the option would have expired if the
 Optionee had lived and remained in the Company's employ) and on or
 before the second anniversary of the Optionee's Retirement Date.  For
 purposes of this Plan, the term "Retirement Date" shall mean the date
 on which the Optionee's employment with the Company (and any parent or
 subsidiary of the Company) terminates (including termination because of
 death) for a reason other than cause if the Optionee had then attained
 age 55 and completed ten calendar years of service with the Company
 (or any parent or subsidiary of the Company).

          (d)  If an Optionee's employment is terminated for any reason
 other than voluntary resignation, discharge for cause or death, any 
 option held by the Optionee may be exercised at any time which is both
 before the time the option would otherwise expire and within three
 months after the date of such cessation of employment, but only with
 respect to that number of shares of Stock which the Optionee would have
 been permitted to purchase under his option immediately before the date
 of termination of such Optionee's employment.  In the event an Optionee
 has attained his Retirement Date, (i) the provisions of Section 8(b)
 and of the preceding sentence shall not be applicable to such
 Optionee's nonqualified stock options and (ii) such Optionee's
 nonqualified stock options may be exercised at any time which is both
 before the time the option would

                                     -6-

 otherwise expire and on or before the second anniversary of the
 Optionee's Retirement Date, but only with respect to that number of
 shares of Stock which the Optionee would have been permitted to
 purchase under his option immediately before the date of termination of
 such Optionee's employment.

          9.   ADJUSTMENTS FOR CHANGES IN CAPITALIZATION, ETC.  If the
 Company shall, after the Effective Date, change its Stock into a
 greater or lesser number of shares through a stock dividend, stock
 split-up or combination of shares, then        

  (i)  the number of shares of Stock then subject to the Plan but
               which are not then subject to any outstanding option;
         (ii)  the number of shares of Stock subject to each then
               outstanding option or (to the extent not previously
               exercised); and

        (iii)  the price per share payable upon exercise of each then
               outstanding option, shall all be proportionately 
               increased or decreased as of the record date for such
               stock dividend, stock split-up or combination of shares

               in order to give effect thereto.  Notwithstanding any
               such proportionate increase or decrease, no fraction of a
               share of Stock shall be issued upon the exercise of an
               option.  If any split-up or combination of shares shall
               involve a change of par value, the shares of Stock
               subject to options theretofore or

                                     -7-

               thereafter granted shall be the shares of Stock as so
               changed.

          If, after the Effective Date, there shall be any change in the
 Stock of the Company other than through a stock dividend, stock 
 split-up or combination of shares, then if (and only if) the Committee
 shall determine that such change equitably requires an adjustment in
 the number or kind or option price of shares of Stock then subject to
 an option, or the number or kind of shares remaining subject to the
 Plan, such adjustment as the Committee shall determine is equitable
 and as shall be approved by the Board shall be made and shall be
 effective and binding for all purposes of such option and the Plan.
 If any member of the Board shall, at the time of such approval, be an
 Optionee, he shall not participate in action in connection with such
 adjustment.

          10.  ADMINISTRATION OF THE PLAN.

          (a)  The Plan shall be administered by the Committee, which
 shall consist of three or more persons selected by the Board from its
 members.  The Committee shall have authority to determine who are, from
 time to time, eligible employees, to construe the Plan, to prescribe,
 amend and rescind rules and regulations for the administration of the
 Plan, to amend or modify the Plan in such manner as the Committee deems
 required to make the Plan conform to the provisions of any federal or
 state laws, or regulations issued thereunder, or practically workable,
 and to take any other action necessary or advisable for the effective

                                     -8-

 administration of the Plan; provided, however, that no such amendment
 or modification of the Plan shall affect the provisions of any option
 granted before such amendment or modification to the detriment of any
 Optionee unless such amendment or modification is required to comply
 with any applicable law or regulation, and provided, further, that any
 such amendment of the Plan extending the period within which options
 may be granted under the Plan, or increasing the number of shares of
 Stock to be optioned under the Plan (except as provided in Section 9
 hereof), or reducing the minimum purchase price per share provided in
 the Plan (except as provided in Section 9 hereof), or changing the
 class of employees to whom options may be granted under the Plan shall,
 in each case, be subject to approval by the Board.  Decisions of the
 Committee shall be final.  Members of the Committee may be removed by
 the Board.  Vacancies in the Committee may be filled, and additional
 members may be appointed from time to time by the Board.  The decision
 of a majority in number of the members of the Committee, from time to
 time acting, shall be deemed to be the decision of the Committee, and a

 majority in number of members of the Committee, from time to time
 acting, shall constitute a quorum of the Committee for the transaction
 of any business.  No member of the Committee may be an individual who
 is or has been for at least one year prior to selection to the
 Committee, eligible for participation in the Plan.

          (b)  The authority granted the Board of Directors in this
 section of the Plan shall be exercised solely by those directors who
                                     -9-

 are not, and have not been for at least one year prior to such
 exercise, eligible for participation in the Plan.

          11.  STOCKHOLDERS' RIGHTS UPON EXERCISE.  An Optionee shall
 not, by reason of the Plan or any option granted pursuant to the Plan,
 have any rights of a stockholder of the Company; however, upon each
 exercise of an option under the Plan, the Optionee shall have, with
 respect to the number of shares of Stock as to which such option is
 then being exercised, all rights of a stockholder of record from the
 date of such exercise, irrespective of whether certificates to evidence
 the shares of Stock with respect to which the option was exercised
 shall have been issued on such date.

          12.  THE RIGHT OF EMPLOYER TO TERMINATE EMPLOYMENT.  Nothing
 contained in the Plan or in any option granted pursuant to the Plan
 shall confer upon any Optionee any right to be continued in the
 employment of the Company, or any parent or subsidiary of the Company,
 or interfere in any way with the right of such Optionee's employer to
 terminate his employment at any time with or without cause.

          13.  GOVERNMENT APPROVALS.  If at any time the Company shall
 be advised by its counsel that the exercise of any option or the
 delivery of shares of Stock upon the exercise of an option is required
 to be approved, registered or qualified under any applicable law, or
 must be accompanied or preceded by a prospectus or similar circular
 meeting the requirements of any applicable law, the Company will use

                                     -10-

 its best efforts to obtain such approval, to effect such registrations
 and qualifications, or to provide such prospectus or similar circular
 within a reasonable time, but exercise of the options or delivery by
 the Company of certificates for shares of Stock may be deferred until
 such approvals, registrations or qualifications are effected, or until
 such prospectus or similar circular is available.

          14.  DISCONTINUANCE OF THE PLAN.  The Board may decrease the
 number of shares issuable under the Plan or discontinue and terminate
 the Plan at any time, but no such decrease, discontinuance or
 termination shall affect any options granted before such decrease,
 discontinuance or termination.

          15.  MERGER, REORGANIZATION OR CHANGE IN CONTROL.

          (a)  Nothing contained in this Plan or in any option granted
 under the Plan shall in any way prohibit the Company from merging with

 or consolidating into another corporation, or from selling or
 transferring all or substantially all of its assets, or from
 distributing all or substantially all of its assets to its stockholders
 in liquidation, or from dissolving and terminating its corporate
 existence; and in any such event (other than a merger in which the
 Company is the surviving corporation and after which the Company
 remains an independent, publicly held corporation), the Company or any
 surviving party to any such merger, consolidation, or sale or transfer
 of assets may provide by resolution of its Board of Directors that all
 rights of the person or persons entitled to exercise then outstanding
 options granted under the Plan, and such options, shall wholly and
 completely terminate at the time of any such

                                     -11-

 merger, consolidation, sale or transfer of assets, liquidation, or
 dissolution, except that adequate provision for such person or persons
 shall be made in accordance with paragraph (b) below.

          (b)  In the event that (i) any individual, corporation,
 partnership or other person or group of persons or entities becomes the
 beneficial owner, directly or indirectly, of 45% or more of the
 Company's then outstanding Common Stock ("Change in Control") or (ii)
 any merger, consolidation, liquidation, dissolution or termination
 after which the Company will not survive as an independent,
 publicly-owned corporation or any sale or transfer of all or
 substantially all of the Company's assets ("Reorganization") occurs,
 then the Company shall pay with respect to each outstanding option
 under this Plan an amount equal to (x) the difference between the Fair
 Market Value (as defined in (c) below) and exercise price of the
 option, multiplied by (y) the number of shares of Stock subject to
 such option.  Such payment shall be made in cash within 30 days after,
 in the case of a Reorganization requiring approval by the Company
 stockholders, the date of such approval and, in the case of a Change in
 Control, the date upon which such change occurs.

          (c)  Solely for purposes of (b) above, "Fair Market Value"
 shall mean the greater of (i) the highest price per share of the
 Company's Common Stock (x) paid by the acquiring person within twelve
 months of the occurrence of the Change in Control to effect such change

                                     -12-

 or (y) provided for in any agreement for the Reorganization or
 (ii) fair market value determined in accordance with Section 17
 of this Plan.

          16.  EFFECTIVE DATE OF PLAN,  The Plan has been adopted by the
 Board on June 27, 1985, and the Plan shall be deemed to have become
 effective on such date.

          17.  MISCELLANEOUS.

          (a)  The transfer of an employee from the Company to a parent
 or subsidiary of the Company or from a parent or subsidiary of the
 Company to the Company or another parent or subsidiary of the Company
 shall not be a termination of employment or an interruption of
 continuous employment for the purposes of the Plan.

          (b)  As used in the Plan, the terms "parent" and "subsidiary"
 shall have the meanings ascribed to them in Sections 421, 422A and 425
 of the Code.

          (c)  Except as otherwise provided, for purposes of this Plan,
 the fair market value of a share of Stock on a specified day shall be
 the mean between the high and low sale price per share as reported for
 such day (or if such day is not a business day, for the immediately
 preceding business day) on a national stock exchange, or if the Stock
 is not listed on such an exchange, on the NASDAQ national market
 system.

          (d)  No option or shares of Stock issuable under the Plan shall
 be transferable or assignable either by the voluntary or involuntary act
 of the Optionee or by operation of law, or be liable for any debts or

                                     -13-

 liabilities of the Optionee, except as provided herein.

     Section 18.  Notwithstanding any other provision of this Plan or of
 any option agreement relating to any option granted hereunder, the
 consummation of the transactions contemplated by that certain Agreement
 and Plan of Merger, dated as of August 24, 1997, by and among Wausau
 Paper Mills Company, WPM Holdings, Inc. and the Company on
 substantially the terms and conditions set forth therein as of August
 24, 1997 shall not be deemed to constitute a "Change in Control" or any
 other transaction described in Section 11(b) of this Plan and of any
 corresponding or similar provision of any such option agreement.  
 Without limiting the generality of the foregoing, the consummation of
 such transactions shall not result in the payment of any cash to any
 holder of an option granted under this Plan.

                                     -14-

 extent that such ownership existed with respect to the Corporation
 prior to the Corporate Transaction, and (C) individuals who were

     (iv)  The Woodson Entities acquire beneficial ownership of more
 than 35% of the Outstanding Corporation Common Stock or Outstanding

 families and their respective descendants (the "Smith Family"), heirs

                                     -17-

 or legatees of any of the Smith Family members, transferees by will,
 laws of descent or distribution or by operation of law of any of the
 foregoing (including of any such transferees) (including any executor
 or administrator of any estate of any of the foregoing), any trust
 established by either of David B. Smith or Katherine S. Smith, whether
 pursuant to last will or otherwise, any partnership, trust or other
 entity established primarily for the benefit of, or any other Person
 the beneficial owners of which consist primarily of, any of the
 foregoing or any Affiliates or Associates of any of the foregoing or
 any charitable trust or foundation to which any of the foregoing
 transfers or may transfer securities of the Corporation (including
 any beneficiary or trustee, partner, manager or director of any of the
 foregoing or any other Person serving any such entity in a similar
 capacity).

     For purposes of this Section 15(a), the terms "Affiliate" and
 "Associate" shall have the meanings ascribed to such terms in Rule
 12b-2 of the General Rules and Regulations under the Exchange Act as in
 effect on the date of this Plan.

     (b)

     (i) In the event of a Change in Control,

          (A)  all options outstanding on the date on which such Change
     in Control has occurred (the "Change in Control Date") shall, to 
     the extent not then exercisable or vested, immediately become
     exercisable in full, and

          (B)  each Optionee may elect, with respect to each option held
     by such Optionee on the Change in Control Date (the Optionee's 
     "Election Right"), to surrender such option for an immediate lump
     sum cash payment in an amount equal to the product of (1) the
     number of shares of common stock of the Corporation (for purposes
     of this Section 15(b), "Shares") then subject to the option as to
     which the election is being exercised, multiplied by (2) the
     excess, if any, of (a) the greater of (i) the Change in Control
     Price or (ii) the highest fair market value of a Share on any day
     in the 60-day period ending on the Change in Control Date, over (b)
     the option price of such option.  For purposes of this Section
     15(b), the "Change in Control Price" shall mean, if the Change in
     Control is the result of a tender or exchange offer or a Corporate
     Transaction (as defined in Section 15(a)(iii), the highest price
     per Share paid in such tender or exchange offer or Corporate 
     Transaction.  To the extent that the consideration paid in any such
     transaction consists all or in part of securities or other noncash

     consideration, the value of such securities or other noncash

                                     -18-

     consideration shall be determined in the sole discretion of the
     Committee.

     (ii) The exercise of an Election Right must be in writing, specify
 the option or options and the number of Shares as to which the election
 is being exercised, and be delivered to the Secretary of the
 Corporation 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 Corporation's home office on or before the 60th day
 following the Change in Control Date.

     (iii) All payments due an Optionee pursuant to the provisions of
 this Section 15(b) shall be made by the Corporation on or before the
 5th business day following the date on which the Optionee's election
 has been delivered to the Corporation pursuant to Section 15(b)(ii).

     (iv)  Notwithstanding any other provision of this Section 15(b), if
 the grant or the exercise of an Optionee's Election Right or payment of
 cash provided for in Section 15b)(i) would make a Change in Control
 transaction ineligible for pooling-of-interests accounting treatment
 under APB No. 16, that, but for the nature of such grant or exercise of
 Election Rights or payment of cash, would otherwise be eligible for
 such pooling-of-interests accounting treatment, the Committee shall
 have the right and authority to substitute for the cash payments to be
 made to the Optionee pursuant to Section 15(b)(ii), Shares with a fair
 market value, determined as of the date of delivery of such Shares,
 equal to the cash that would otherwise be payable to such Optionee in
 connection with the exercise of an Optionee's Election Right hereunder
 or, to the extent necessary to preserve such pooling-of-interests
 accounting treatment, to otherwise modify, eliminate, or terminate such
 Election Right.
