EXHIBIT 10.7

                     MOSINEE PAPER CORPORATION
                      1994 STOCK OPTION PLAN

     Mosinee Paper Corporation, a corporation with its principal place of
 business located in Mosinee, Wisconsin (the "Company"), hereby adopts the
 Mosinee Paper Corporation 1994 Stock Option Plan (the "Plan"), as set
 forth herein.

     Section 1.  PURPOSE.  The Plan is intended to attract and retain key
 employees and directors by permitting key employees of the Company or any
 parent or subsidiary of the Company and directors of the Company to
 acquire authorized and unissued, or reacquired, shares of common stock of
 the Company 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 such directors to continue serving as directors 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.

     It is the express intent of the Company that, subject to Section
 6.2(h) 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

                                   -1-

 Section 422 of the Code.  A key employee or director may be granted and
 may hold one or more options under this Plan.

     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 346.667.

     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") and the definition of
 an "Outside Director" in the regulations under Section 162(m) of the Code.
 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 key employees on
 such terms, which need not be the same as to all Employee Optionees, as

 will, in its discretion and subject only to the specific limitations
 elsewhere contained in

                                   -2-

 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 AND DIRECTORS.

     Section 4.1  KEY EMPLOYEES.  Key employees (who may also be officers
 or directors) of the Company (or any parent or subsidiary of the Company)
 shall be eligible to be granted options pursuant to Section 5 of 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  DIRECTORS.  Directors of the Company (who may also be key
 employees or officers of the Company (or any parent or subsidiary of the
 Company)) shall be eligible to be granted options pursuant to Section 7 of
 the Plan.  Directors of the Company who are not also employees of the
 Company (or any parent

                                   -3-

 or subsidiary of the Company) shall not be eligible to be granted options
 under Section 5 of the Plan.

     Section 5.  GRANTING OF OPTIONS TO KEY EMPLOYEES.  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 "Employee Optionees."

     Section 6.  TERMS AND CONDITIONS OF THE KEY EMPLOYEE OPTIONS.

     Section 6.1  WRITTEN INSTRUMENT.  Each option to purchase Shares
 granted under Section 5 of the Plan shall be evidenced by a written option
 agreement signed on behalf of the Company and the Employee Optionee which
 sets forth the name of the Employee 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

                                   -4-

 incorporate by reference all applicable terms, conditions and limitations
 set forth in the Plan.

     Section 6.2  TERMS AND CONDITIONS OF THE KEY EMPLOYEE OPTIONS.  In
 addition to any other limitations, terms and conditions specified in the
 Plan, each option granted under Section 5 of the Plan shall, as to each
 Employee Optionee, satisfy the following requirements:

          (a)  DATE OF GRANT.  Options must be granted on or before October
 19, 2004.

          (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 either
 an Incentive Stock Option or Non-Qualified Stock option granted under
 Section 5 of the Plan will be not less than one hundred 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

                                   -5-

               (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 an
                    Employee Optionee otherwise than by will or the laws of
                    descent and distribution nor can it be exercised by
                    anyone other than the Employee Optionee during the
                    Employee Optionee's lifetime.

               (ii) The Committee may, in its discretion, authorize all or
                    a portion of any Non-Qualified Stock Options to be
                    granted to an Employee Optionee under Section 5 of the
                    Plan or which were granted to any Employee Optionee on
                    or before October 31, 1996, to permit transfer by the
                    Employee Optionee to (A) the spouse, children or

                    grandchildren of the Employee Optionee ("Immediate
                    Family"),

                                   -6-

                    (B) a trust for the exclusive benefit of the Employee
                    Optionee or the Employee Optionee's Immediate
                    Family, (C) a partnership in which the Employee
                    Optionee or the Employee Optionee's Immediate Family
                    are the only partners, or (D) to a former spouse of the
                    Employee 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 not be 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

                                   -7-

                    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 Employee 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.  Neither
                    the Company, the Committee or any Employee 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 Employee
                    Optionee, a transferred option shall be exercisable by
                    the transferee only to the extent, and for the periods
                    specified in Section 6(e) as if

                                   -8-

                    such option had not been transferred and (ZZ) no
                    option granted prior to October 31, 1996, may be
                    transferred until such option has been held by the
                    Employee Optionee for a period of not less than six
                    months after the date on which such option was
                    granted.

          (e)  EMPLOYMENT.  No option granted under Section 5 of the Plan
 shall be exercisable unless the Employee 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 (and subject to
 Section 12 herein); provided, however, that in the event an Employee
 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 granted under Section
 5 of the Plan 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

                                   -9-

 desirable or necessary in order to carry out the purposes and
 requirements of the Plan.

          (g)  LIMITATION ON OPTION GRANTS.  No Employee Optionee may be
 granted options under Section 5 of the Plan in any calendar year with
 respect to more than 50,000 Shares.

          (h)  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.  GRANTING OF OPTIONS TO DIRECTORS.  On January 1, 1997 Non-
 Qualified Stock Options to purchase that number of Shares equal to the
 product of 1,000 and the number of years

                                  -10-

 (determined by treating any partial year as a whole year) then remaining
 in the term for which the director has been elected, reelected or
 appointed shall be granted to each director of the Company.  Such options
 shall be expressly conditioned upon the approval of the amendments to the
 Plan providing for the granting of options to directors pursuant to this
 Section 7 and increasing the number of Shares which may be issued under
 options granted pursuant to the Plan by the Company's stockholders at the
 next annual meeting of the Company's stockholders, and such options shall

 not be effective if such amendments are not so approved.  On June 1, 1997
 and on each June 1 thereafter Non-Qualified Stock Options to purchase
 that number of Shares equal to the product of 1,000 and the number of
 years (determined by treating any partial year as a whole year) in the
 term for which the director has been elected, reelected or appointed
 shall be granted to each director of the Company who was elected,
 reelected or appointed to the board of directors of the Company during
 the previous twelve months.  Directors of the Company who have been
 granted Non-Qualified Stock Options pursuant to this Section 7 shall be
 referred to herein as "Director Optionees".

     Section 8.  TERMS AND CONDITIONS OF THE DIRECTOR OPTIONS.

     Section 8.1  WRITTEN INSTRUMENT.  Each option to purchase Shares
 granted under Section 7 of the Plan shall be evidenced by a written option
 agreement signed on behalf of the Company and the Director Optionee which
 sets forth the name of the Director Optionee, the date granted, the option
 price, the number of

                                  -11-

 Shares subject to the option and the other terms and conditions set forth
 below.  Such option agreement shall incorporate by reference all
 applicable terms, conditions and limitations set forth in the Plan.

     Section 8.2  TERMS AND CONDITIONS OF THE OPTIONS.  In addition to any
 other limitations, terms and conditions specified in the Plan, each option
 granted under Section 7 of the Plan shall, as to each Director Optionee,
 satisfy the following requirements:

          (a)  DATE OF GRANT.  Options must be granted on or before
 October 19, 2004.

          (b)  EXPIRATION.  Each option granted under Section 7 of the Plan
 shall cease to 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
 option granted under Section 7 of the Plan will be one hundred 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

                                  -12-

               (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.  Options granted under Section 7 of the
 Plan may be transferred by the Director Optionee to (A) the spouse,
 children or grandchildren of the Director Optionee ("Immediate Family"),
 (B) a trust for the exclusive benefit of the Director Optionee or the
 Director Optionee's Immediate Family, (C) a partnership in which the
 Director Optionee or the Director Optionee's Immediate Family are the only
 partners, or (D) to a former spouse of the Director 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 not be consideration for any such transfer, and (Y) once transferred
 pursuant to the preceding provisions of this Section 8.2(d), no subsequent
 transfer of any options shall be permitted except a transfer by will or
 the laws of descent and distribution.  Following transfer, the terms and
 conditions of the Plan and the written option agreement relating

                                  -13-

 to such option shall continue to be applicable in all respects to the
 Director 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.  Neither the
 Company, the Committee or any Director 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, following
 the termination of a Director Optionee's membership on the board of
 directors of the Company (including for this purpose membership as a
 director emeritus of the Company) a transferred option shall be
 exercisable by the transferee only to the extent, and for the periods
 specified in Section 8.2(e) as if such option had not been transferred.

          (e)  BOARD MEMBERSHIP.  No option granted under Section 7 of the
 Plan shall be exercisable unless the Director Optionee shall have been a
 member of the board of directors of the Company (including for this
 purpose membership as a director emeritus 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 (and subject to Section 12
 herein); provided, however, that in the event a Director Optionee dies
 while a member of the board of directors of the Company (including for
 this purpose membership as a director emeritus of the Company) or within

                                  -14-

 ninety days after such membership had terminated, the board membership
 period requirement described above shall be deemed to have been satisfied.

          (f)  LIMITATION ON OPTION GRANTS.  No Director Optionee may be
 granted options in any calendar year with respect to more than 4,000
 Shares.

     Section 9.  EXERCISE AND PAYMENT OF OPTION PRICE.

     Section 9.1  EXERCISE OF OPTIONS.  Options shall be exercised as to
 all or a portion of the Shares by delivery of an irrevocable 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 minimum required tax withholding for options held
 by Employee Optionees).  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 prepaid and addressed to such officer at the
 Company's home office.  No option may be exercised with respect to a
 fractional share of stock.  Notwithstanding the fact that an option has
 been transferred pursuant to Section 6.2(d)(ii), the Employee Optionee
 granted such option shall remain liable for any required tax withholding.

     Section 9.2  PAYMENT FOR SHARES.  Payment of the option price (plus
 minimum required tax withholding for options held by an Employee Optionee
 may be made by (a) tendering cash (in the form of a check or otherwise) in
 such amount, or (b) with the

                                  -15-

 consent of the Committee, 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 Employee Optionee granted
 such option shall remain liable for any required tax withholding.

     Section 10.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION.  If the
 Company shall, after the Effective Date, change its common 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 then subject to the plan but which
                    are not then subject to any outstanding option;

               (ii) the number of Shares subject to each then outstanding
                    option (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 shall be issued upon the exercise of
 an option.  If any split-up or combination of shares shall involve a

                                  -16-

 change of par value, the Shares subject to options theretofore or
 thereafter granted shall be the Shares 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, or other change listed in Section 11 herein, 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
 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.

     Section 11.  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

 death within ninety days after such employment had terminated, an option
 may be exercised, to the extent exercisable by the Employee Optionee
 immediately prior to his death, in whole or in part by the Employee
 Optionee's estate or designee by will, or, if applicable, the transferee
 of such option pursuant to Section 6.2(d), 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

 the Director Optionee immediately prior to his death, in whole or in part
 by the Director Optionee's estate or designee by will, or, if applicable,
 the transferee of such option pursuant to Section 8.2(d) but only if the

 expressly reserve the right to

                                  -22-

          (a)  The transfer of an Employee Optionee from the Company to a
 parent or subsidiary of the Company or from a parent or subsidiary of the

 employment for the purpose of the Plan.

 Shares may be deferred until such approvals, registrations or
 qualifications are effected, or until such prospectus or similar circular
 is available.
