Exhibit 10(f)
            SUPPLEMENTAL RETIREMENT BENEFIT AGREEMENT



     Agreement made as of this 15th day of November, 1991 by and
between Mosinee Paper Corporation, a Wisconsin corporation (the
"Corporation") and Richard L. Radt, of Wausau, Wisconsin
("Mr. Radt").

     WITNESSETH:

     WHEREAS, Mr. Radt is employed as President and Chief
Executive Officer of the Corporation and has performed his duties
in a manner highly satisfactory to the Corporation; and

     WHEREAS, the Corporation has determined to provide Mr. Radt
with deferred compensation in the form of a supplemental
retirement benefit in recognition of Mr. Radt's agreement to
continue to perform services for the Corporation as its President
and Chief Executive Officer;

     NOW, THEREFORE, the Corporation and Mr. Radt agree as
follows:

     1.   Payment of Supplemental Retirement Benefit.

          (a)   On the last to occur of (1) August 1, 1992, or (2)
     the date which is fifteen days after the date of Mr. Radt's
     termination of employment with each of the Corporation and
     the Corporation's subsidiaries, the Corporation shall pay to
     Mr. Radt, if then living, otherwise to Mr. Radt's Beneficiary
     or Beneficiaries (determined in accordance with paragraph 3)
     an amount equal to the Supplemental Retirement Benefit Amount
     (determined in accordance with paragraph 2); provided,
     however, that no payment shall be made to Mr. Radt's
     Beneficiary or Beneficiaries pursuant to this subparagraph
     (a) if a payment to such Beneficiary or Beneficiaries has
     been made pursuant to subparagraph (b).  

          (b)   If Mr. Radt dies prior to August 1, 1992, the
     Corporation shall, within fifteen days of the date of his
     death, pay to Mr. Radt's Beneficiary or Beneficiaries
     (determined in accordance with paragraph 3) an amount equal
     to the Supplemental Retirement Benefit Amount (determined in
     accordance with paragraph 2).  

     2.   Supplemental Retirement Benefit Amount.  

          (a)   Subject to the provisions of subparagraph (b), the
     "Supplemental Retirement Benefit Amount" shall be an amount
     equal to the excess of (1)  $214,312, over (2) that portion
     of the lump sum present value of the monthly retirement
     benefit payable to Mr. Radt under the Mosinee Retirement Plan
     which is attributable to Credited Service accrued by Mr.
     Radt, as determined under the Mosinee Retirement Plan,
     through July 31, 1992.  For purposes of this
     subparagraph (a):
<PAGE>
                (1)   the lump sum present value of the monthly
          retirement benefit payable under the Mosinee Retirement
          Plan shall be determined in accordance with the
          provisions of such plan governing lump sum payment
          options, and

                (2)   the portion of the lump sum present value of
          the monthly retirement benefit payable to Mr. Radt under
          the Mosinee Retirement Plan which is attributable to
          Credited Service accrued by Mr. Radt through July 31,
          1992 shall be determined by multiplying the lump sum
          present value of such retirement benefit by a fraction,
          (i) the numerator of which is the number of months of
          Credited Service accrued by Mr. Radt under the Mosinee
          Retirement Plan as of July 31, 1992 and (ii) the
          denominator of which is the total number of months of
          Credited Service accrued by Mr. Radt under the Mosinee
          Retirement Plan as of the date his employment with each
          of the Corporation and the Corporation's subsidiaries
          terminates.

          (b)   Despite any other provision of this Agreement, in
     the event that Mr. Radt's termination of employment with each
     of the Corporation and the Corporation's subsidiaries occurs
     after July 31, 1992, the "Supplemental Retirement Benefit
     Amount" shall be equal to (1) the amount of the "Supplemental
     Retirement Benefit Amount" otherwise determined in
     subparagraph (a) plus (2) interest on such amount calculated
     for each calendar quarter, or portion thereof, at an annual
     rate equal to the prime rate published in The Wall Street
     Journal on the first day of such calendar quarter from and
     after August 1, 1992 through the day immediately preceding
     payment of the Supplemental Retirement Benefit Amount.

     3.   Mr. Radt's Beneficiary or Beneficiaries.  For purposes
of this agreement, Mr. Radt's "Beneficiary or Beneficiaries" shall
mean such person or persons or organization or organizations as
Mr. Radt from time to time may designate by a written designation
filed with the Corporation during Mr. Radt's life.  Any amounts
payable hereunder to Mr. Radt's Beneficiary or Beneficiaries shall
be paid in such proportions and subject to such trusts, powers and
conditions as Mr. Radt may provide in such designation.  Each such
designation, unless otherwise expressly provided therein, may be
revoked by Mr. Radt by a written revocation filed with the
Corporation during Mr. Radt's  life.  If more than one such
designation shall be filed by Mr. Radt with the Corporation, the
last designation so filed shall control over any revocable
designation filed prior to such filing.  To the extent that any
amounts payable under this agreement to Mr. Radt's Beneficiary or
Beneficiaries are not effectively disposed of pursuant to the
above provisions of this paragraph, either because no designation
was in effect at Mr. Radt's death or because a designation in
effect at Mr. Radt's death failed to dispose of such amounts in
their entirety, then for purposes of this agreement, Mr. Radt's
"Beneficiary or Beneficiaries" as to such undisposed of amounts
shall be Mr. Radt's estate.
<PAGE>
     4.   Supplemental Retirement Benefit in Addition to Other
Rights and Benefits.  The rights and benefits conferred upon
Mr. Radt pursuant to this agreement shall be in addition to all
other rights and benefits conferred upon Mr. Radt by the
Corporation by reason of Mr. Radt's employment.

     5.   Nature of Corporation's Obligations and Mr. Radt's
Rights.  Neither Mr. Radt nor any Beneficiary or Beneficiaries of
Mr. Radt shall acquire any right, title or interest in the assets
of the Corporation by reason of this agreement.  To the extent
Mr. Radt or his Beneficiary or Beneficiaries shall acquire a right
to receive payments from the Corporation pursuant to this
agreement, such right shall be no greater than the right of any
unsecured general creditor of the Corporation.

     6.   Assignment by Mr. Radt Prohibited.  This agreement and
Mr. Radt's rights and benefits hereunder shall not be subject to
voluntary or involuntary sale, pledge, hypothecation, transfer or
assignment by Mr. Radt or by his personal representatives or heirs
or any other person or persons or organization or organizations
succeeding to any of Mr. Radt's rights and benefits hereunder.

     7.   Binding Effect.  This agreement shall be binding upon
and inure to the benefit of (1) Mr. Radt, his personal
representatives and heirs and any other person or persons or
organization or organizations succeeding to any of Mr. Radt's
rights or benefits hereunder, and (2) the Corporation and its
successors and assigns.

     8.   Severability.  The invalidity or unenforceability of any
provision of this agreement shall not invalidate or render
unenforceable any other provision of this agreement.

     9.   Counterparts.  This agreement may be executed in several
counterparts, each of which shall be an original and all of which
shall constitute but one and the same instrument.

     10.  Governing Law.  This agreement shall be governed by the
laws of the State of Wisconsin.


     IN WITNESS WHEREOF, the Corporation has caused this agreement
to be executed by an officer thereunto duly authorized, and
Mr. Radt has hereunto set his hand and seal, as of the day and
year first above written.
