EXHIBIT 10.2


                                                            November __, 1996

                           UNISOURCE WORLDWIDE, INC.

                          DIRECTORS' STOCK OPTION PLAN

Purpose--The Unisource Worldwide, Inc. Directors' Stock Option Plan (the "Plan")
      enables directors of Unisource Worldwide, Inc. ("Unisource") to purchase
      common stock of Unisource.  The purpose of the Plan is to promote an
      identity of interest between Unisource and its directors and to attract
      and retain highly competent individuals to serve as members of Unisource's
      Board of Directors (the "Board").  This Prospectus relates to 250,000
      shares of common stock of Unisource issuable upon exercise of options
      granted under the Plan.

Automatic Annual Grants:  Number of Shares and Price--Each year, each director
      who is not otherwise an employee of Unisource or its subsidiaries will
      automatically be granted an option to purchase 800 shares of Unisource
      common stock ("Regular Options") immediately following the annual meeting
      of shareholders.  The exercise price for the Regular Options is 100% of
      the fair market value of the shares on the date of grant.

Elective Annual Grants:  Number of Shares and Price--Each year, each director
      who is not otherwise an employee of Unisource or its subsidiaries may
      elect to receive all or a portion of his or her directors' and trustees'
      fees in the form of options to purchase shares of Unisource common stock
      ("Discounted Options").  The exercise price for Discounted Options is 75%
      of the fair market value of the shares on the date of grant.  The
      Discounted Options will be granted immediately following the annual
      meeting of shareholders.

Exercisability--Regular Options are exercisable six months following the date of
      grant, and Discounted Options are exercisable twelve months following the
      date of the grant, in either case, if the director is then a member of the
      Board.  If a director leaves the Board on account of attainment of
      retirement age, disability or death, the director's options will be fully
      exercisable.  However, if a director ceases to be a member of the Board
      for any reason, any portion of a Discounted Option that is attributable to
      compensation not yet earned shall abate and be cancelled.

Term-- Regular Options have a ten-year term, and Discounted Options have a
      twenty-year term.  When all or part of an option becomes exercisable, it
      will remain exercisable for the balance of its term (except in the event
      of a director's death). In the event of a director's death, the director's
      personal representative has twelve months to exercise any outstanding
      options (unless the options otherwise expire prior to the end of such
      period).

Conversion of Options Held by Former Directors of Alco Standard Corporation--
      Unisource directors who were members of the Board of Directors of Alco
      Standard Corporation ("Alco") immediately before the distribution of
      Unisource stock to the shareholders of Alco may elect to have their
      options to purchase Alco stock that were granted under Alco's stock option
      plans for directors converted into options to purchase Unisource stock.
      The conversion will be based on a conversion formula approved by the Alco
      Board of Directors and the Unisource Board that is intended to preserve
      the economic value of the options as of the conversion date.  The new

                                       1

 
      Unisource options shall have terms substantially identical to the terms of
      the Alco options that they replace and shall be administered under the
      terms of this Plan.

Exercise--An optionee may exercise all or any part of an exercisable option by
      delivering written notice to Unisource.  The full exercise price for the
      shares shall be paid in cash, by check payable to Unisource, or in such
      other form of consideration as may be approved by Unisource.  After
      exercise, the optionee will receive a stock certificate for the number of
      shares purchased, and is free thereafter to sell the shares, subject to
      compliance with Rule 144.

Tax Consequences--Options granted under the Plan are nonqualified stock options.
      Exercise of an option will generally result in ordinary income to the
      optionee at the time of exercise.

                                    THE PLAN

General

     The Plan was adopted by the Board, effective December 1, 1996, and has been
approved by Alco, as the sole shareholder of Unisource.  A copy of the Plan is
included as part of this Prospectus.  The following summary is qualified in its
entirety by reference to the Plan.

     Unisource's principal office is located in Valley Forge, Pennsylvania
19482.  Its telephone number is (610) 296-8000.

Purpose of the Plan

     The purpose of the Plan is to promote an identity of interest between
Unisource and its directors and to attract and retain highly competent
individuals to serve as members of the Board.



Administration of the Plan

     The Plan is administered by the Human Resource Committee of the Board (the
"Committee").  Members of the Committee are ordinarily appointed for a term
coinciding with their term of office; however, the members serve at the pleasure
of the Board and may be changed at any time.  The Committee has authority to
interpret the Plan, to prescribe, amend and rescind rules and regulations
relating to it, and to make all other determinations and take all other actions
deemed necessary or advisable in administering the Plan.  The determinations of
the Committee on these matters shall be conclusive.  No member of the Committee
will be liable for any action taken or decision made in good faith relating to
the Plan or any grant thereunder.  The Committee may, from time to time, appoint
an Administrator of the Plan, who will be responsible for the general
administration of the Plan under the policy guidance of the Committee.  The
Administrator will be an employee of Unisource and will be compensated for
services and expenses by Unisource according to Unisource's normal employment
policies, without special or additional compensation, other than reimbursement
of expenses, for services as the Administrator.


Number of Shares Available Under the Plan

     The maximum number of shares of Unisource common stock for which options
may be granted under the Plan is 250,000 shares, subject to adjustment as
provided herein.  If the outstanding shares of Unisource common stock are
increased, decreased or exchanged for a different number or kind of shares or
other securities, or if additional shares or other property (other than ordinary
cash dividends) are distributed with respect to such shares of Unisource common
stock or other securities, through merger, consolidation, sale of all or
substantially all of the assets of Unisource, reorganization, recapitalization,
reclassification, dividend, stock split, reverse stock split, spin off, split
off, or other distribution with respect to such shares of common stock or other
securities, an appropriate and proportionate adjustment will be 

                                       4

 
made in (i) the maximum number and kind of shares reserved for issuance under
the Plan, (ii) the number and kind of shares or other securities subject to then
outstanding options under the Plan, and (iii) the price for each share subject
to any then outstanding options under the Plan. No fractional shares will be
issued under the Plan on account of any such adjustments.

     The shares of Unisource common stock issuable upon exercise of options
granted under the Plan may be unissued shares or shares held in Unisource's
treasury, including shares bought on the open market.  If an option expires,
terminates or is canceled prior to being exercised in full, any shares remaining
subject to such option will again be available for the grant of options under
the Plan.


Grant of Regular Options

     Each individual who is not an employee of Unisource or any of its
subsidiary corporations and who is elected a director of Unisource at an annual
meeting of shareholders of Unisource will automatically be granted a Regular
Option to purchase 800 shares of Unisource common stock (subject to adjustment
as described herein) immediately following the annual meeting of shareholders.
An individual who ceases to be a director of Unisource at the annual meeting of
shareholders shall not be entitled to receive an award.

     The option exercise price for each Regular Option shall be 100% of the fair
market value of a share of Unisource common stock on the date of grant of the
option.  For purposes of the Plan, the fair market value of Unisource stock is
defined as the closing price as reported on the New York Stock Exchange
Composite Tape.



Grant of Discounted Options

     Discounted Options will be granted automatically immediately following each
annual meeting of Unisource's shareholders to each director who is not an
employee of Unisource or any of its subsidiary corporations and who has filed
with Unisource an election to receive stock options in lieu of all or a
specified portion of his or her Annual Retainer (as defined below) to be earned
during each Plan Year.  Discounted Options granted under the Plan will entitle
the optionee to purchase shares of Unisource common stock at a price equal to
75% of the fair market value of the stock on the date of grant.

     A "Plan Year" is the twelve month period beginning March 1 and ending the
last day of February thereafter.  A director's election shall remain in effect
for each Plan Year unless the Administrator shall have received notice of any
change which the director wishes to make before the shareholder's meeting to
which the change applies.

     "Annual Retainer"  is the amount of fees which the director will be
entitled to receive during each  Plan Year for serving as a director or a member
of one or more of the committees of the Board or for serving as a trustee of any
of Unisource's employee benefit plan trusts.  The term does not include per
meeting attendance fees or fees for any other services provided to Unisource.

                                       5

 
     After a director has executed an appropriate election, the number of
options for shares of Unisource stock that the director will be entitled to
receive is determined by dividing the director's Annual Retainer (or the portion
thereof which the director has elected to receive as stock options) by 25% of
the fair market value of a share of Unisource stock (representing the difference
between the fair market value and the exercise price on the date of grant).  No
options for fractional shares will be issued, nor will cash payments be made in
lieu of fractional shares.


Option Agreements

     Options will be evidenced by stock option awards to be issued by Unisource,
which shall specify the number of shares of stock for which the options are
issued, the exercise price, and all other terms of the options.  In the event of
any discrepancy between a stock option award and the Plan, the provisions of the
Plan shall govern.  In the event of any discrepancy between this Prospectus and
either a stock option award or the Plan, such award or the Plan, as appropriate,
shall govern.


Exercisability and Term of Options

     Exercisability of Options.  Regular Options may be exercised at any time
     -------------------------                                               
after six months from the date of grant, and Discounted Options may be exercised
at any time after twelve months from the date of grant, provided, in either
case, that the director is a member of the Board on the date on which the
options become exercisable.  If a director ceases to be a member of the Board by
reason of attainment of retirement age, disability or death, the director's
options will be fully exercisable (except as provided below). If a director
ceases to be a member of the Board for any reason, any portion of a Discounted
Option that is attributable to compensation not yet earned shall abate and be
canceled.

     Term of Options.  The term of Regular Options will be ten years from the
     ----------------                                                        
date of grant, and the term of Discounted Options will be twenty years from the
date of grant.  No option may be exercised after the expiration of its term.



Exercise of Rights Upon Ceasing to be a Member of the Board

     The rights of a director in an option that has become exercisable under the
Plan will not terminate upon such director's ceasing to be a member of the Board
for any reason (including retirement because of age, death or disability),
except as provided below.  However, any exercisable option granted to a director
that is outstanding on the date of his or her death may be exercised by the
administrator of such director's estate, the executor under his or her will, or
the person to whom the option shall have been validly transferred pursuant to
the laws of descent and distribution, but not beyond the first to occur of (i)
the expiration of twelve months from the date of such director's death, or (ii)
the specified expiration date of the option.  Upon the first to occur of the
foregoing events, the option shall terminate.

                                       6

 
Conversion of Options Held by Former Alco Directors

     Unisource directors who were members of the Board of Directors of Alco
immediately before the distribution of Unisource shares to the shareholders of
Alco may elect to have their options to purchase Alco stock that were granted
under Alco's stock option plans for directors converted into options to purchase
Unisource stock.  The Board of Directors of Alco and the Unisource Board shall
approve the formula to be used for the conversion. The vesting and other terms
of the new Unisource options shall be identical to the terms of the Alco options
that they replace, except that service on the Unisource Board shall be
considered continued service for purposes of the options.  The new Unisource
options shall be administered under the terms of this Plan.


Exercise of Options

     Options granted under the Plan may be exercised by delivering written
notice to Unisource.  The full exercise price for the shares as to which options
are exercised shall be paid in cash, by check payable to Unisource, or in such
other form of consideration as may be approved by the Administrator or by the
Committee.


Duration of Plan

     No options may be granted pursuant to the Plan after November 30, 2006.


Nontransferability of Options

     No option granted pursuant to this Plan shall be transferable by the
optionee other than by will or the laws of descent and distribution, and an
option may be exercisable during the optionee's lifetime only by the optionee.


Plan and Options Not to Affect Directorship

     Neither the Plan, nor the granting of an option, nor any other action taken
pursuant to the Plan, constitutes evidence of any agreement or understanding,
expressed or implied, that Unisource will nominate any director for reelection
by Unisource's shareholders.



Rights in Stock

     An optionee has no rights as a shareholder with respect to any shares
covered by an option until the date of issuance of a share certificate to the
optionee representing such shares.  No adjustment will be 

                                       7

 
made for dividends or other rights for which the record date is prior to the
date such share certificate is issued.


Outstanding Options Under the Plan

     Information as to the number of shares subject to outstanding options and
for which options remain available under the Plan, as well as exercises of
options and expiration dates of outstanding options, will be provided, to the
extent required by law , in Unisource's annual report or proxy statement.


Requirements of Law

     The obligation of Unisource to sell, issue and deliver shares upon exercise
of options granted under the Plan is subject to all applicable laws, rules and
regulations, and to such approvals by any governmental agencies as may be
required.


Amendment of the Plan

     The Board has complete power and authority to terminate and in any respect
amend or modify the Plan, except to the extent that the approval of Unisource's
shareholders is required under applicable law.  No amendment, modification or
termination of the Plan may adversely affect the rights of participants with
respect to any option previously granted, without their consent.


Employee Retirement Income Security Act of 1974

     The Plan is not a qualified plan under Section 401(a) of the Internal
Revenue Code of 1986, as amended, and is not subject to any provisions of the
Employee Retirement Income Security Act of 1974.


               RESALE OF SHARES ACQUIRED UPON EXERCISE OF OPTIONS


     The Plan imposes no limitation or restriction on resales of shares acquired
upon exercise of options granted thereunder.  However, any optionee who is an
"affiliate" of Unisource at the time of resale of shares acquired upon exercise
of options granted under the Plan may make such resales only pursuant to an
effective registration statement specifically relating to such resales, pursuant
to Rule 144 under the Securities Act, or in a transaction otherwise exempt from
registration under the Securities Act.  Affiliates may not use this Prospectus
for the reoffer or resale of such shares.  Optionees who are not affiliates of
Unisource at the time of resale are not restricted by the Securities Act with
respect to resale of their shares.

                                       8

 
                        FEDERAL INCOME TAX CONSEQUENCES


     All options to be granted under the Plan are non-qualified stock options
which are not entitled to special tax treatment under Section 422 of the
Internal Revenue Code of 1986, as amended.  Generally, there are no tax
consequences to an optionee or to Unisource when a non-qualified stock option is
granted.  When such an option is exercised, the excess of the then fair market
value of the shares over the exercise price will constitute ordinary income to
the optionee, and Unisource will be entitled to a corresponding tax deduction.
Upon disposition of the shares by the optionee, long term or short term capital
gain or loss, as the case may be, will be recognized, equal to the difference
between the amount realized on such disposition and the optionee's basis in the
shares, which will include the amount previously recognized as ordinary income.
The capital gain holding period will commence on the day the optionee acquires
the shares pursuant to exercise of the option.

     The foregoing is not a complete summary of income tax consequences to
participants or to Unisource.  It does not reflect the effects of foreign, state
or local tax laws.

     BECAUSE OF THE COMPLEXITY OF THE FEDERAL TAX LAWS RELATING TO STOCK OPTION
PLANS AND THE APPLICATION OF STATE AND LOCAL LAWS, PARTICIPANTS IN THE PLAN ARE
ADVISED TO CONSULT THEIR PERSONAL TAX ADVISERS REGARDING THESE MATTERS.

                                   Exhibit A


                           UNISOURCE WORLDWIDE, INC.

                          DIRECTORS' STOCK OPTION PLAN


       1.   Purpose.  The purpose of this Directors' Stock Option Plan (the
  "Plan") of Unisource Worldwide, Inc. ("Unisource") is to promote an identity
  of interest between Unisource and its directors and to attract and retain
  highly competent individuals to serve as members of Unisource's Board of
  Directors.

       2.   Effective Date.  This Plan shall become effective as of December 1,
  1996.

       3.   Stock.  There are authorized for issuance or delivery upon the
  exercise of options to be granted from time to time under the Plan an
  aggregate of 250,000 shares of Unisource's common stock, no par value, subject
  to adjustment as provided hereinafter in paragraph 13.  Such shares may be, in
  whole or in part, authorized but unissued shares, whether now or hereafter
  authorized, or issued shares which have been reacquired by Unisource.  If any
  option under this Plan shall expire, terminate or be canceled for any reason
  without having been exercised in full, the shares which have not been
  purchased thereunder shall again become available for the purpose of this
  Plan.

       4.   Administration.

            (a)  The Plan shall be administered by the Human Resources Committee
  (the "Committee") of the Board of Directors of Unisource (the "Board"), except
  as provided otherwise in the Plan.

            (b)  The Committee shall have authority to interpret the Plan, to
  prescribe, amend and rescind rules and regulations relating to it, and to make
  all other determinations and take all other actions deemed necessary or
  advisable in administering the Plan.

            (c)  The determinations of the Committee on the matters referred to
  in this paragraph 4 shall be conclusive.  No member of the Committee shall be
  liable for any action taken or decision made in good faith relating to the
  Plan or any grant hereunder.

            (d)  An Administrator of the Plan may from time to time be appointed
  by the Committee.  Such Administrator shall be responsible for the general
  administration of the Plan under the policy guidance of the Committee.  The
  Administrator shall be in the employ of Unisource and shall be compensated for
  services and expenses by Unisource according to its normal employment
  policies, without special or additional compensation, other than reimbursement
  of expenses, for his or her services as the Administrator.

       5.   Automatic Annual Stock Option Awards.

10

 
            (a)  Each year, for as long as the Plan remains in effect, each
  person who is not an employee of Unisource or any of its present or future
  subsidiary corporations (as defined in Section 425 of the Internal Revenue
  Code of 1986, as amended) and who is elected a director of Unisource at
  Unisource's annual meeting of shareholders shall automatically be granted an
  option (a "Regular Option") to purchase 800 shares of common stock of
  Unisource (subject to adjustment as provided hereinafter in paragraph 13)
  immediately following the annual meeting of shareholders.  An individual who
  ceases to be a director of Unisource at the annual meeting of shareholders
  shall not be entitled to receive an award.  Each Regular Option shall be
  evidenced by an option award document which shall comply with and be subject
  to the applicable terms and conditions set forth in the Plan.

            (b)  The exercise price for each Regular Option granted under the
  Plan shall be 100% of the Fair Market Value of shares of Unisource common
  stock on the date on which the option is granted (the "Grant Date").  For
  purposes of this Plan, "Fair Market Value" shall be the closing price per
  share of Unisource common stock as reported on the New York Stock Exchange
  Composite Tape.

            (c)  Each Regular Option may be exercised after the date that is six
  months following the Grant Date, if the director is a member of the Board on
  such date.  However, if the director ceases to be a member of the Board on
  account of  attainment of retirement age specified by the Board, death or
  disability, as determined by the Board, the Regular Option shall be fully
  exercisable as of the date on which the director ceases to be a member of the
  Board.

            (d)  Each Regular Option shall have a term of ten years from the
  Grant Date.  No option granted under the Plan shall be exercisable after the
  expiration of its term.  Each Regular Option shall be subject to termination
  before its date of expiration as herein provided in paragraph 7 below.

       6.   Elective Annual Stock Option Awards.

            (a)  Each year, for as long as the Plan remains in effect, each
  person who is not an employee of Unisource or any of its present or future
  subsidiaries, who is elected a director of Unisource at Unisource's annual
  meeting of shareholders, and who has filed with Unisource an election to
  receive a stock option in lieu of the Annual Retainer (as defined below), or
  some portion thereof, to be earned by such director in each Plan Year  (as
  defined below) during which he or she shall serve as director, shall receive
  an option (a "Discounted Option")  to purchase shares of Unisource common
  stock.  The Discounted Option shall be granted immediately following the
  annual meeting of shareholders.  An individual who ceases to be a director of
  Unisource at the annual meeting of shareholders shall not be entitled to
  receive an award.  Each Discounted Option shall be evidenced by an option
  award document which shall comply with and be subject to the applicable terms
  and conditions set forth in the Plan.

            (b)  The number of shares of Unisource common stock subject to each
  Discounted Option granted to a director for a Plan Year shall be equal to the
  nearest number of whole shares determined in accordance with the following
  formula:
 
     Annual Retainer               =          Number of Shares
     -------------------------

     Fair Market Value minus
     Exercise Price

  No fractional shares shall be issued, nor shall cash payments be made in lieu
  of fractional shares.  "Exercise Price" shall be defined as set forth in
  Subsection 6(c), and "Fair Market Value" shall be defined as set forth in
  Subsection 5(b).  "Annual Retainer" shall mean the amount of fees which the
  director will be entitled to receive during a Plan Year for serving as a
  director or a member of one or more committees of the Board or a trustee of
  any of Unisource's employee benefit plan trusts; provided, however, that if a
  director elects to receive a stock option in lieu of only a portion of the
  Annual Retainer, the Annual Retainer for purposes of the foregoing formula
  shall equal the portion of the Annual Retainer so elected.  For purposes of
  this Plan, "Annual Retainer" shall not include fees or expenses for attendance
  at meetings of the Board or any committee of the Board or for any other
  services to be provided to Unisource except as set forth herein. The "Plan
  Year" is the twelve month period beginning each March 1 and ending on the last
  day of February.

            (c)  The exercise price for each Discounted Option granted under the
  Plan shall be 75% of the Fair Market Value of shares of Unisource common stock
  on the Grant Date. 

            (d)  Each Discounted Option may be exercised after the date that is
  twelve months following the Grant Date, if the director is a member of the
  Board as of such date. However, except as provided below, if the Director
  ceases to be a member of the Board on account of attainment of retirement age
  specified by the Board, death or disability, as determined by the Board, the
  Discounted Option shall be fully exercisable as of the date on which the
  director ceases to be a member of the Board.

            (e)  Notwithstanding the foregoing, if a director ceases to be a
  member of the Board for any reason, any portion of a Discounted Option that is
  attributable to a portion of an Annual Retainer that has not yet been earned
  shall automatically abate and be canceled.

       7.   Termination of Directorship.  The rights of a director in an option
  granted under the Plan shall not terminate upon such director's termination as
  a director for any reason (including retirement because of age, death or
  disability), except as provided in Subsection 6(e) above or except as provided
  below. Except as provided in Subsection 6(e) above, any option granted to a
  director and outstanding on the date of his or her death may be exercised by
  the administrator of such director's estate or the person to whom the option
  shall have been validly transferred by will or the laws of descent and
  distribution, but not beyond the first to occur of (i) the expiration of
  twelve months from the date of the director's death, or (ii) the specified
  expiration date of the option.  Upon the first to occur of the foregoing
  events, the option shall terminate.

       8.   Conversion of Alco Options.  In connection with the distribution by
  Alco Standard Corporation ("Alco) of the common stock of Unisource to Alco's
  shareholders, the Unisource directors who were members of the Alco Board of
  Directors immediately before the distribution may elect to have their
  outstanding options to purchase Alco stock that were granted under Alco's
  stock option plans for directors converted into options to purchase Unisource
  common stock.  The options to purchase Alco stock shall be converted into
  options to purchase Unisource stock according to a formula approved by the
  Alco Board of Directors and the Unisource Board that is intended to preserve
  the economic value of the options as of the date of the conversion.  In all
  other respects, the terms of the Unisource options shall be identical to the
  terms of the replaced Alco options, except that membership on the Board of
  Unisource shall be considered continued Board membership for purposes of the
  Unisource options.  The new Unisource options shall be administered pursuant
  to the terms of this Plan.

       9.   Exercise of Options.  Options may be exercised only by written
  notice to Unisource.  The full exercise price for the shares as to which
  options are exercised shall be paid in cash, by check payable to Unisource, or
  in such other form of consideration as shall be approved by the Administrator
  or by the Committee.



       10.  Limitations.

           (a)  No options may be granted pursuant to this Plan after November
  30, 2006.

           (b)  No option granted pursuant to this Plan shall be transferable
  by the optionee otherwise than by will or the laws of descent and
  distribution, and an option shall be exercisable during the optionee's
  lifetime only by the optionee.

       11.   Withholding Taxes.  Whenever shares of Unisource common stock
  are to be issued or delivered, the Committee shall have the right to require
  the recipient to remit to Unisource an amount sufficient to satisfy any
  required federal, state or local income or employment tax withholding
  requirements.

       12. Limitation of Rights.

           (a)  Neither the Plan, nor the granting of an option, nor any other
  action taken pursuant to the Plan, shall constitute evidence of any agreement
  or understanding, expressed or implied, that Unisource will nominate any
  director for reelection by Unisource's shareholders.

           (b)  An optionee shall have no rights as a shareholder with respect
  to any shares covered by an option until the date of issuance of a share
  certificate to the optionee for such shares.  No adjustment shall be made for
  dividends or other rights for which the record date is prior to the date such
  share certificate is issued.

       13. Adjustments.  If the outstanding shares of Unisource common stock
  are increased, decreased or exchanged for a different number or kind of shares
  or other securities, or if additional shares or other property (other than
  ordinary cash dividends) are distributed with 

13

 
  respect to such shares of Unisource common stock or other securities, through
  merger, consolidation, sale of all or substantially all of the assets of
  Unisource, reorganization, recapitalization, reclassification, dividend, stock
  split, reverse stock split, spin off, split off, or other distribution with
  respect to such shares of common stock or other securities, an appropriate and
  proportionate adjustment shall be made in (i) the maximum number and kind of
  shares reserved for issuance under the Plan, (ii) the number and kind of
  shares or other securities subject to then outstanding options under the Plan,
  and (iii) the price for each share subject to any then outstanding options
  under the Plan. No fractional shares will be issued under the Plan on account
  of any such adjustments.

       14.  Amendment and Termination.  The Board shall have complete power and
  authority to terminate and in any respect amend or modify the Plan, except to
  the extent that the approval of Unisource's shareholders is required under
  applicable law.  No amendment, modification or termination of the Plan may
  adversely affect the rights of participants with respect to any option
  previously granted, without their consent.

       15.  Government and Other Regulations.  The obligation of Unisource to
  sell, issue and deliver shares upon exercise of options granted under the Plan
  shall be subject to all applicable laws, rules and regulations, and to such
  approvals by any governmental agencies as may be required.

       16.  Other Actions.  Nothing contained in the Plan shall be construed to
  limit the authority of Unisource to exercise its corporate rights and powers
  including, but not limited to, the right of Unisource (a) to grant options for
  proper corporate purposes otherwise than under the Plan to any employee or
  other person, firm or corporation or association, or (b) to grant options to,
  or assume the options of, any person in connection with the acquisition, by
  purchase, lease, merger, consolidation or otherwise, of the business and
  assets (in whole or in part) of any person, firm, corporation or association.

       17.  Governing Law.  The Plan shall be governed by and construed in
  accordance with the laws of the Commonwealth of Pennsylvania.
