         tion 6 of the addendum to this Agreement.

             (i) above who were still in office as of the date
             the Board approved such election or nomination;
             
                  (c)  Within three hundred sixty-five (365)
             days following the date on which any "person" (as
             such term is used in Sections 13(d) and 14(d) of
             the Securities Exchange Act of 1934, as amended
             (the "l934 Act")) that has acquired Shares pursuant
             to a tender offer subject to Section 14(d) of the
             1934 Act becomes entitled to vote twenty percent
             (20%) or more of the aggregate voting power of the
             capital stock of the Corporation issued and
             outstanding; and
             
                  (d)  Within thirty (30) days prior to any
             dissolution or liquidation of the Corporation or
             any merger or consolidation in which the Corpo-
             ration is not the surviving corporation, but not
             earlier than the date on which any required
             stockholder approval is obtained.
             
         If an option is not exercised during any thirty (30) day
         period described in (a) or (b) above, the option shall
         terminate at the close of business on the last day of the
         thirty (30) day period; provided, however, that if periods
         described in (a) and (b) are contiguous or overlap, unexer-
         cised options shall terminate at the close of business on the
         last day of the second thirty (30) day period.
         
                  4.   If the Option is designated in Section 6 of
         the addendum to this Agreement as being granted with a stock
         appreciation right, under the conditions described herein,
         Employee may surrender all or part of this Option and exer-
         cise the stock appreciation right in lieu of exercising all
         or any part of this Option, provided that the Fair Market
         Value of the Common Stock on the date of such exercise is
         higher than the Exercise Price specified in Section 2 of the
         addendum to this Agreement.  The exercise of a stock appreci-
         ation right shall be referred to herein as the "call"
         thereof.  Upon the call of a stock appreciation right
         Employee shall be entitled to receive payment of an amount
         equal to the difference obtained by subtracting the aggregate
         option price of the shares subject to the Option (or the
         portion thereof) from the Fair Market Value of such Shares on
         the date of such call.  For all purposes under this Agreement
         (unless the context requires otherwise), the terms "exercise"
         or "exercisable" shall be deemed to include the terms "call"
         or "callable" as such terms may apply to a stock appreciation
         right granted in conjunction with the Option and in the event
         of the call of the stock appreciation right the underlying
         
         
                                   -5-
                  
         
         
         
         Option will be deemed to have been exercised for all purposes
         under the Plan.
         
                  If the Option is not designated in Section 6 of the
         addendum to this Agreement as being granted with a stock
         appreciation right, the Option shall nevertheless automati-
         cally include a stock appreciation right that may be called
         in the event of a Change in Control, only during the periods
         described in Subparagraphs (a), (b), (c) or (d) of Para-
         graph 3.  In the case of any stock appreciation right that is
         called during either of the thirty (30) day periods
         described in Paragraph 3(a) or 3(d), for purposes of
         measuring the value of the stock appreciation right, "Fair
         Market Value" shall be the greater of (a) the value of the
         consideration per share that the Employee would have received
         in connection with such transaction as a stockholder of the
         Corporation if he or she had exercised the Option prior to
         the consummation of the transaction described in Para-
         graph 3(a) or Paragraph 3(d) or (b) the value determined in
         good faith by the Committee (as composed on the day
         preceding the date of consummation of the transaction
         described in Paragraph 3(a) or 3(d)), taking into
         consideration all relevant facts and circumstances.
         
                  Payment of a stock appreciation right shall be
         made as soon as reasonably practicable following receipt by
         the Corporation of the form described in Paragraph 8.  Pay-
         ment of the stock appreciation right shall be made in such
         form as may be permitted pursuant to the Rules as in effect
         on the date the stock appreciation right is called.
         
                  5.   The term of this Option shall end and (any
         other provision of the Plan to the contrary notwithstanding)
         this Option shall not be exercisable after seven (7) years
         from the Date of Grant if this Option is designated as an
         Incentive Stock Option in Section 4 of the addendum to this
         Agreement or ten (10) years from the Date of Grant if this
         Option is designated as a Nonqualified Stock Option in
         Section 4 of such addendum, or, if earlier, upon the
         termination of Employee's employment with the Corporation or
         its Subsidiaries, subject to the following provisions:
         
                  (a)  If the termination of employment is
             caused by Employee's death, this Option, to the
             extent that it was exercisable under Paragraph 3 of
             this Agreement at the date of death and had not
             previously been exercised or called, may be
             exercised or called, within twelve (12) months
             after Employee's death by Employee's executors or
             administrators or by any person or persons who
             
             
                                  -6-
                   
         
         
         shall have acquired this Option directly from
         Employee by bequest or inheritance.
         
             (b)  If the termination of Employee's
         employment is caused by Disability or retirement
         under the Potlatch Corporation Salaried Employees'
         Retirement Plan, this Option, to the extent it was
         exercisable under Paragraph 3 of this Agreement at
         the date of such termination and had not
         previously been exercised, may be exercised or
         called within twelve (12) months after the date of
         such termination (three (3) months, in the case of
         termination by reason of retirement).
         
             (c) If the termination of Employee's
         employment is for any reason other than death,
         Disability, or retirement under the Potlatch
         Corporation Salaried Employees' Retirement Plan,
         this Option, to the extent that it was exercisable
         under Paragraph 3 of this Agreement at the date of
         such termination and had not previously been
         exercised, may be exercised within three (3) months
         after the date of such termination; provided,
         however, that in such case the right to call a
         stock appreciation right shall terminate on the
         date Employee's employment terminates unless
         Employee requests and the Committee permits the
         call of the stock appreciation right within three
         (3) months after the date of such termination.
         Notwithstanding the foregoing, if the termination
         of employment is by reason of Employee's
         misconduct, the option shall cease to be
         exercisable or callable on the date of such
         termination.  As used herein "misconduct" means
         that Employee has engaged in unfair competition
         with the Corporation or a Subsidiary, induced any
         customer of the Corporation or a Subsidiary to
         breach any contract with the Corporation or a
         Subsidiary, made any unauthorized disclosure of any
         of the secrets or confidential information of the
         Corporation or a Subsidiary, committed an act of
         embezzlement, fraud or theft with respect to the
         property of the Corporation or a Subsidiary, or
         engaged in conduct which is not in good faith and
         which directly results in material loss, damage or
         injury to the business, reputation or employees of
         the Corporation or a Subsidiary.  The Committee
         shall determine whether Employee's employment is
         terminated by reason of misconduct.  In making such
         determination the Committee shall act fairly and
         
         
                                -7-
              
         
         
         
             shall give Employee an opportunity to be heard and
             present evidence on Employee's behalf.
             
                  6.   The Corporation agrees that it will at all
         times during the Option Period reserve and keep available
         sufficient authorized but unissued or reacquired Common
         Stock to satisfy the requirements of this Agreement.  The
         number of Shares so reserved and the Exercise Price thereof
         shall be proportionately adjusted for any increase or
         decrease in the number of issued and outstanding Shares by
         reason of stock dividends, split-ups, consolidations,
         recapitalizations, reorganizations or like events, as
         determined by the Committee pursuant to the Plan.
         
                  7.    Subject to any required action by the
         stockholders, if the Corporation shall be the surviving
         corporation in any merger, consolidation or other
         reorganization, this Option shall pertain and apply to the
         securities to which a holder of the number of Shares subject
         to this Option would have been entitled.  Except insofar as
         Paragraph 3 (and Paragraph 4) permit the exercise of Options
         (and stock appreciation rights) within a specified time
         period before or after a Change in Control, a dissolution or
         liquidation of the Corporation or a merger, consolidation or
         other reorganization in which the Corporation is not the
         surviving corporation shall cause this Option to terminate on
         the effective date of such dissolution, liquidation or
         reorganization, unless the agreement of merger, consolidation
         or reorganization shall otherwise provide.  In the event that
         the Corporation undergoes a reverse merger transaction,
         Employee (or Employee's representative) shall be entitled to
         receive the same consideration in such transaction
         (including, without limitation, cash) as other shareholders
         are entitled to receive.
         
                  8.    Employee, or Employee's representative, may
         call twenty percent (20%) or more of that portion of the
         Option which has become vested in accordance with Paragraph 3
         of this Agreement at any time during each applicable Call
         Period, except as requested by Employee or Employee's
         representative and approved by the Committee.  For purposes
         of the Plan, the date of call shall be the date a form
         provided by the Corporation for this purpose is filed by the
         Employee or the Employee's representative and received by the
         Secretary of the Corporation.
         
             Employee, or Employee's representative, may exercise
         this Option by giving written notice to the Corporation at
         San Francisco, California, attention of the Secretary,
         specifying the election to exercise the Option, the number of
         
         
                                    -8-
                  
         
         
         
         Shares in respect of which it is being exercised and the
         method of payment for the amount of the Purchase Price of the
         Shares as to which this Option is exercised.  Such payment
         shall be made:
         
                  (a)  In United States dollars delivered at the
             time of exercise;
             
                  (b) Subject to the conditions stated in rules
             and regulations adopted by the Corporation to
             govern its stock option program, by the surrender
             of Shares in good form for transfer, owned by the
             person exercising this Option and having an
             aggregate Fair Market Value on the date of exercise
             equal to the Purchase Price; or
             
                  (c) In any combination of Subparagraphs (a)
             and (b) above, if the total of the cash so paid and
             the Fair Market Value of the Shares so surrendered
             equals the Purchase Price of the Shares with
             respect to which this Option is being exercised.
             
                  The notice shall be signed by the person or persons
         exercising this Option, and in the event this Option is being
         exercised by the representative of Employee, it shall be
         accompanied by proof satisfactory to the Corporation of the
         right of the representative to exercise the Option.  No Share
         shall be issued until full payment therefor has been made.
         The Corporation shall thereafter cause to be issued a cer-
         tificate or certificates for the Shares as to which this
         Option shall have been so exercised, registered in the name
         of the person or persons so exercising the Option (or in the
         name of such person or persons and another person as commun-
         ity property or as joint tenants), and cause such certificate
         or certificates to be delivered to or upon the order of such
         person or persons.
         
                  9.   Payments or transfers to the Employee under
         this Agreement shall be limited to the amount (the "Capped
         Amount") necessary to avoid characterization of any amount
         payable to the Employee (including, but not limited to,
         amounts payable under this Agreement) as an "excess
         parachute payment" as defined in section 280G of the Code,
         except in the event that the total amount that the Employee
         would receive from all "parachute payments" (as defined in
         Code section 280G), net of all applicable taxes, including
         the excise tax that would be imposed pursuant to Code section
         4999, would exceed the Capped Amount, net of all applicable
         taxes.
         
         
                                    -9-
   

                  The firm of independent certified public accoun-
         tants serving as the Corporation's outside auditor as of the
         date of a Change in Control shall determine whether any
         amount would constitute an "excess parachute payment,"
         disregarding any payments or benefits available to the
         Employee under any plan, contract or program if the Employee
         irrevocably elects to relinquish or not exercise such
         payments or benefits before the payment or enjoyment thereof.
         
                  10.  In the event the Corporation determines that
         it is required to withhold state or federal income tax as a
         result of the exercise of this Option, as a condition to the
         exercise of the Option, Employee will make arrangements
         satisfactory to the Corporation to enable it to satisfy such
         withholding requirements.
         
                  11.   Neither Employee nor Employee's
         representative shall have any rights as a stockholder with
         respect to any Shares subject to this Option until such
         Shares shall have been issued and delivered to Employee or
         Employee's representative.
         
                  12.  Unless the Shares to be acquired are regis-
         tered under the Securities Act, Employee represents and
         agrees that upon the exercise of the Option herein granted
         Employee will purchase such Shares for the purpose of
         investment and without present intention of resale.  Unless
         at the time Employee gives notice of the exercise of this
         Option, the Shares to be issued are registered under the
         Securities Act, the notice shall include a statement to the
         effect that all Shares in respect of which this Option is
         being exercised are being purchased for investment, and
         without present intention of resale, and will not be sold
         without registration under the Securities Act or exemption
         therefrom, and such other representations as the Committee
         may require.  The Corporation may permit the sale or other
         disposition of any Shares acquired pursuant to any such
         representation if it is satisfied that such sale or other
         disposition would not be in contravention of applicable state
         or Federal securities laws.  Unless the Corporation shall
         determine that, in compliance with the Securities Act or
         other applicable statute or regulation, it is necessary to
         register any of the Shares with respect to which the exercise
         of this Option has been made, and unless such registration,
         if required, has been completed, certificates to be issued
         upon the exercise of this Option shall contain the following
         legend:
         
                  "The Shares represented by this certificate
             have not been registered under the Securities Act
             
             
                                 -10-
      
      
             of 1933 and may be offered, sold or transferred
             only if registered pursuant to the provisions of
             that Act or if an exemption from registration is
             available."
             
                  13.   Except as otherwise provided herein, the
         Option herein granted and the rights and privileges
         conferred hereby shall not be transferred, assigned, pledged
         or hypothecated in any way (whether by operation of law or
         otherwise) and shall not be subject to sale under execution,
         attachment or similar process.  Upon any attempt to
         transfer, assign, pledge, hypothecate or otherwise dispose of
         this Option, or of any right or privilege conferred hereby,
         contrary to the provisions hereof, or upon any attempted
         sale under any execution, attachment or similar process upon
         the rights and privileges conferred hereby, this Option and
         the rights and privileges conferred hereby shall immediately
         become null and void.
         
                  14.   Nothing in this Agreement shall be construed
         as giving Employee the right to be retained as an employee or
         as impairing the rights of the Corporation to terminate his
         or her employment at any time, with or without cause.
         
                  15.   This Agreement shall be interpreted and con-
         strued in accordance with the laws of the State of
         California.
