                         ---------------------------------- 

          (a) As of the Effective Date, Unisource shall assume, retain and be
liable for all wages, salaries, welfare, pension, incentive compensation and
other employee-related liabilities and obligations ("Employee Liabilities") with
respect to Active Unisource Employees, except as specifically provided otherwise
in this Agreement. Unisource shall assume, retain and be liable for Employee
Liabilities with respect to Former Unisource Employees only as provided in this
Agreement, except that if any Employee Liability arises with respect to an
Active or Former Unisource Employee that is not covered in this Agreement (other
than worker's compensation liability, which is covered in the Distribution

          Section 2.02.  Offer of Employment; Benefit Plan Coverage.
                         ------------------------------------------ 

          (a) Unisource shall offer those persons who are employed by the Alco
Group immediately before the Effective Date, and who have been designated as
Active Unisource Employees, employment with the Unisource Group as of the
Effective Date, on terms and conditions, and with aggregate compensation and
benefits, substantially similar to those of their employment with the Alco Group
immediately before the Effective Date.

          (b) Active Unisource Employees shall not continue to be active
participants in benefit plans maintained by the Alco Group on or after the
Effective Date and, instead, shall be eligible to participate in applicable
Unisource plans, as determined by Unisource, as of the Effective Date. Unisource
shall treat service of each Active Unisource Employee with the Alco Group before
the Effective Date as if such service had been with Unisource for purposes of
determining eligibility to participate, eligibility for benefits, benefit forms
and vesting under plans maintained by Unisource, to the extent the corresponding
Alco plans gave credit for such service.

                         ----------------------   
Unisource has established on its books for financial accounting purposes
liabilities and reserves for pension, welfare and other employee benefit plan
obligations that will be retained or assumed by Unisource under this Agreement,
and Alco has adjusted the liabilities and reserves on its books for financial
accounting purposes to take into account Unisource's assumption or retention of
liabilities under this Agreement. The initial adjustments as of October 1, 1996
have been made on an estimated basis. After the parties have finally calculated
the actual liabilities under this Agreement, each party shall appropriately
adjust its liabilities and reserves to reflect the actual


                                       5

 
amount of the liabilities and reserves that are properly allocable to that
party.  Neither party shall have any obligation to make payments or transfer
assets to the other party with respect to such adjustments.

          Section 2.04.  Collective Bargaining Agreements.  As of the Effective 
                         --------------------------------   
Date, Unisource shall assume any and all obligations of the Alco Group under
collective bargaining agreements with respect to Active or Former Unisource
Employees and any and all obligations of the Alco Group to contribute to multi-
employer plans (as defined in Section 3(37) of ERISA) with respect to Active or
Former Unisource Employees. On and after the Effective Date, any withdrawal
liability obligations, and any expenses or other amounts related thereto, that
are payable to any multi-employer plan with respect to Active or Former
Unisource Employees, regardless of whether such obligations relate to services
performed before or after the Effective Date, shall be the sole responsibility
of Unisource.  Attached as Schedule 2.04, for information purposes only, is a
list of all multi-employer plans covering Active Unisource Employees as of the
Effective Date.

          Section 2.05.  Administration.  Unisource and Alco shall each make its
                         --------------                                         
appropriate employees and data regarding employee benefit coverage available to
the other at such reasonable times as may be necessary for the proper
administration by the other of any and all matters relating to employee benefits
and worker's compensation claims affecting its employees.

                                  ARTICLE III
                           PENSION AND SAVINGS PLANS

          Section 3.01.  Plans to be Transferred to Unisource.
                         ------------------------------------ 

          (a) As of the Effective Date, Unisource shall assume all of the Alco
Group's obligations with respect to the pension and savings plans listed on
Schedule 3.01 (the "Transferred Plans").  Unisource (or a member of the
Unisource Group) shall maintain each Transferred Plan on and after the Effective
Date and shall take all actions necessary to be substituted for the Alco Group
with respect to each Transferred Plan.  The Alco Group shall cease to be the
plan sponsor for the Transferred Plans as of the Effective Date.

          (b) The assets of Alco's Group Trust Fund (the "Group Trust Fund")
allocable to each Transferred Plan whose assets are held in the Group Trust Fund
shall be transferred in kind to a trust fund established by Unisource for the
Transferred Plan as described in Section 3.03.  The assets of any other Alco
trust fund maintained for a Transferred Plan shall be transferred in kind on the
Effective Date to a trust fund established by Unisource for the Transferred
Plan.

          Section 3.02.  Participating Companies Pension Plan.
                         ------------------------------------ 

          (a) As of the Effective Date, Unisource shall establish a defined
benefit pension plan and trust (the "Unisource Pension Plan") covering Active
Unisource Employees who are participants in Alco's Participating Companies
Pension Plan (the "Alco Pension Plan") that shall be initially comparable to the
Alco Pension Plan. The Unisource Pension Plan shall be qualified under Sections
401 and 501 of the Code.

                                       7

 
          (b) As of the Effective Date, Alco shall direct the trustees of the
Alco Pension Plan to divide the assets of the Alco Pension Plan into three
portions, as follows:

               (i) The "Former Employees Portion" shall be that portion of the
          fair market value of the assets of the Alco Pension Plan as of the
          Effective Date equal to the accumulated benefit obligations ("ABO") of
          all participants in the Alco Pension Plan who are not Active Alco
          Employees or Active Unisource Employees as of the Effective Date.

               (ii) The "Active Alco Employees Portion" shall be an amount equal
          to the total fair market value of the assets of the Alco Pension Plan
          as of the Effective Date, less the Former Employees Portion,
          multiplied by a fraction, the numerator of which is the aggregate
          projected benefit obligations (as defined below) ("PBO") of the Active
          Alco Employees in the Alco Pension Plan as of the Effective Date and
          the denominator of which is the total PBO of all Active Alco Employees
          and Active Unisource Employees in the Alco Pension Plan as of the
          Effective Date.

               (iii) The "Active Unisource Employees Portion" shall be an amount
          equal to the total fair market value of the assets of the Alco Pension
          Plan as of the Effective Date, less the Former Employees Portion,
          multiplied by a fraction, the numerator of which is the aggregate PBO
          of the Active Unisource Employees in the Alco Pension Plan as of the
          Effective Date and the denominator of which is the total PBO of all
          Active Alco Employees and Active Unisource Employees in the Alco
          Pension Plan as of the Effective Date.


                                       8

 
               (iv) Attached as Schedule 3.02 is a calculation of the Former
          Employees Portion, Active Unisource Employees Portion and Active Alco
          Employees Portion computed as of December 31, 1995 in accordance with
          this Section 3.02.

          (c) After the foregoing division has been made, Alco shall direct the
trustees of the Alco Pension Plan to transfer to the Unisource Pension Plan
assets equal to the Active Unisource Employees Portion.  The Former Employees
Portion and the Active Alco Employees Portion shall remain in the Alco Pension
Plan, and Alco shall remain responsible for providing benefits with respect to
participants who are not Active Unisource Employees.

          (d) The terms "accumulated benefit obligations" and "projected benefit
obligations" shall have the meanings given those terms in the Statement of
Financial Accounting Standards No. 87 ("FAS 87"), using the same assumptions as
are used by Alco for financial reporting purposes under FAS 87 as of September
30, 1996.

          (e) For purposes of calculating the value of the Alco Pension Plan
assets as of the Effective Date, there shall be included a receivable for Alco's
contributions for the plan year ending September 30, 1996 and for the portion of
the 1997 plan year ending on the Effective Date, which shall be calculated
consistent with Alco's past practice for making contributions to the Alco
Pension Plan. Unisource shall reimburse Alco for Unisource's pro rata share of
the contribution relating to the plan year ended September 30, 1996, no later
than the date on which Alco makes such contribution to the Alco Pension Plan.
Unisource shall contribute its pro rata share of the 1997 plan year contribution
to the applicable Unisource pension plan.


                                       9

 
          (f) If the amount calculated for transfer to the Unisource Pension
Plan under the foregoing provisions of this Section 3.02 is not sufficient to
satisfy section 414(l) of the Code, the amount shall be adjusted so as to equal
the minimum amount required by section 414(l) of the Code. If the amount
calculated for transfer to the Unisource Pension Plan under the foregoing
provisions of this Section 3.02 is greater than the maximum amount allowed to be
transferred under section 414(l) of the Code (such that section 414(l) of the
Code would be violated by the transfer), the amount shall be adjusted to the
extent necessary to cause the requirements of section 414(l) of the Code to be
met. In either event, the party whose plan received more assets than the amount
calculated under the foregoing provisions of this Section 3.02 shall make an
appropriate payment directly to the other party to place the parties in the same
economic position as if only the amount calculated under the foregoing
provisions of this Section 3.02 had been transferred.

          (g) Alco shall adjust the amount to be transferred from the Alco
Pension Plan to the Unisource Pension Plan, as calculated above, by a pro rata
share of the Alco Pension Plan earnings, gains and losses, appreciation,
depreciation and expenses for the period between the Effective Date and the date
on which the assets are actually transferred, and by the assets transferred
pursuant to the second sentence of Section 3.03(a).

          (h) The calculations referred to in this Section 3.02 shall be made by
Alco's actuaries and shall be subject to review by Unisource's actuaries.  The
assets shall be transferred in kind as described in Section 3.03.

          (i) The accrued benefits to be credited under the Unisource Pension
Plan as of the Effective Date with respect to Active Unisource Employees shall
not be less than the accrued benefits of the Active Unisource Employees under
the Alco Pension Plan immediately before the Effective Date.

          (j) If an employee of the Unisource Business incurred a long-term
disability before October 1, 1996 and for that reason is not considered an
Active Unisource Employee, and the employee subsequently recovers from the long-
term disability and returns to work with the Unisource Group, Alco shall direct
the trustees of the Alco Pension Plan to transfer an amount equal to the PBO of
such employee from the Alco Pension Plan to the applicable Unisource pension
plan covering such employee. The amount shall be computed and transferred as of
the end of the calendar year in which the employee returns to work and shall be
computed based on the assumptions used by Alco for financial reporting purposes
under FAS 87 as of the end of the fiscal year ending in that calendar year. The
amount to be transferred shall be determined consistent with Section 414(l) of
the Code and shall be transferred within 30 days after the end of the calendar
year in which the employee returns to work. Unisource and its applicable pension
plan shall assume liability for all benefits payable with respect to the
transferred assets. Unisource shall also assume liability for all benefits that
are payable under Alco's Supplemental Retirement Plan with respect to the
employee on and after the date on which the employee returns to work with the
Unisource Group.

          Section 3.03.  Transfer of Pension Plan Assets.
                         -------------------------------

          (a) The assets of Alco's Group Trust Fund allocable to the Transferred
Plans and to the portion of the Alco Pension Plan that is to be transferred to
the Unisource Pension

                                      11

 
Plan shall be transferred in kind to one or more trusts established by Unisource
for the Unisource plans.  Within 30 days after the Effective Date, Alco shall
transfer to the Unisource trust an amount that Alco and Unisource deem
sufficient to cover all benefit payments required to be made with respect to
Active Unisource Employees under the Unisource pension plans before the date on
which the final asset transfer occurs.  The remaining assets shall be
transferred as soon as is practicable after the actuaries finalize their
calculation of the amount to be transferred, and after receipt of any
governmental approvals.

          (b) Alco shall apportion the assets of the Group Trust Fund pro rata,
to the extent practicable, in a fair and equitable manner, consistent with the
fiduciary obligations of Alco and the plan trustees, between the plans remaining
with Alco and the plans or plan assets being transferred to the Unisource trust.
The trustees of the Alco Group Trust Fund have determined that the Alco Common
Stock held in the Group Trust Fund will be allocated to the plans remaining with
Alco and, except as provided below, the Unisource Common Stock held in the Group
Trust Fund will be allocated to the Unisource trust. However, in order to comply
with applicable law, on the date on which assets are transferred to the
Unisource trust, the fair market value of the Unisource Common Stock allocated
to the Unisource trust shall not exceed 10% of the fair market value of the
assets of the applicable Unisource plans. Any Unisource Common Stock that is not
allocated to the Unisource trust as a result of this limit shall be allocated to
the plans remaining with Alco.

          (c) If for any reason the amount transferred from Alco's Group Trust
Fund to the Unisource trust exceeds or is less than the amount that should have
been transferred pursuant to this Article III, an appropriate amount shall be
transferred between the Unisource trust and


                                      12

 
Alco's Group Trust Fund such that Alco's Group Trust Fund and the Unisource
trust will be in the same economic position as if only the correct amount had
been transferred.

Code and shall provide for salary reduction contributions pursuant to Section
401(k) of the Code.

     (b) Assets of the Alco RSP equal to the aggregate account balances of the
Active Unisource Employees under the Alco RSP shall be transferred to the
Unisource RSP as of the Effective Date.  The transfer shall be made in cash,
interests in mutual funds, Alco Common Stock and Unisource Common Stock,
according to the investment of each Active Unisource Employee's account as of
the date on which the transfer is made.  Any outstanding  balances of plan loans
to Active Unisource Employees shall be transferred with the underlying accounts.
The account balances of the Active Unisource Employees shall be valued as of the
date on which the transfer is made, which value shall include the earnings,
gains and losses, appreciation and

                                      13

 
depreciation of the investment funds in which the accounts are invested through
the date on which the transfer is made.  Alco and the Alco RSP shall remain
responsible for providing benefits accrued under the Alco RSP for Former
Unisource Employees.

     (c) After the Effective Date, Unisource shall allow participants in the
Unisource RSP to retain their investment in shares of Alco Common Stock under
the Unisource RSP for such period as Unisource deems appropriate.  Unless
Unisource determines otherwise, Unisource shall allow participants to transfer
investments out of the Alco Common Stock investment fund under the Unisource
RSP, but no investments may be transferred into the Alco Common Stock fund under
the Unisource RSP.

     (d) After the Effective Date, Alco shall allow participants in the Alco RSP
to retain their investment in shares of Unisource Common Stock under the Alco
RSP for such period as Alco deems appropriate.  Unless Alco determines
otherwise, Alco shall allow participants to transfer investments out of the
Unisource Stock Fund under the Alco RSP, but no investments may be transferred
into the Unisource Stock Fund under the Alco RSP.

     (e) Each party shall provide to the other party in a timely manner such
proxy statements, annual reports, and other materials with respect to the
party's stock as may be reasonably requested by the other party.

     (f) Alco shall retain all company-owned life insurance policies purchased
with respect to participants in the Alco RSP, except as otherwise provided in
Section 6.02 with respect to life insurance policies purchased in connection
with deferred compensation plans.

     (g) If an employee of the Unisource Business incurred a long-term
disability before October 1, 1996 and for that reason is not considered an
Active Unisource Employee, and the employee subsequently recovers from the long-
term disability and returns to work with the Unisource Group, Alco shall direct
the trustee of the Alco RSP to transfer assets of the Alco RSP equal to the
account balance of such employee to the Unisource RSP as of the end of the
calendar year in which the employee returns to work.  The transfer shall be made
consistent with Section 414(l) of the Code and subsection (b) above, and shall
be made within 30 days after the end of the plan year in which the Unisource
Employee returns to work.  Unisource and the Unisource RSP shall assume
liability for all benefits payable with respect to the transferred assets.

     (c) Unisource shall submit to the Internal Revenue Service requests for
favorable determination letters with respect to the tax-qualified status of the
Transferred Plans, the Unisource Pension Plan and the Unisource RSP as soon as

                          EMPLOYEE STOCK OPTION PLANS

     Section 4.01.  Employee Stock Option Plans.
                    --------------------------- 

     (a) Unisource shall establish one or more stock option plans for eligible
Active Unisource Employees.  Unisource and Alco shall give each Active Unisource
Employee an opportunity to elect, by December 6, 1996, either:

          (i) To have all the Active Unisource Employee's options to purchase
     Alco Common Stock that are outstanding as of December 31, 1996 and that
     were granted under the Alco Group's stock options plans (both vested and
     unvested options) converted into options to purchase Unisource Common
     Stock, or

          (ii) To retain the Active Unisource Employee's vested options to
     purchase Alco Common Stock that are outstanding as of December 31, 1996
     until March 31, 1997 (but not later than the end of their term), thereby
     forfeiting any unvested options.

For purposes of this Section 4.01, the term "Active Unisource Employee" shall
not include an employee of the Unisource Business who is receiving severance
payments on or after December

                                      16

 
6, 1996; any options to purchase Alco Common Stock that held by such a person
and are outstanding as of December 31, 1996 shall be adjusted as described in
subsection (b) below.  If an Active Unisource Employee elects alternative (ii),
(A) the Active Unisource Employee's unvested Alco options shall terminate as of
the Effective Date, (B) the Active Unisource Employee's vested Alco options
shall be adjusted as described in subsection (b) below, (C) the Active Unisource
Employee's vested Alco options shall be exercisable until March 31, 1997 (but
not beyond the stated term of the options), and (D) any vested Alco options that
are not exercised by March 31, 1997 (or by the end of their term, if sooner)
shall immediately terminate.  If an Active Unisource Employee fails to make an
election, his or her Alco options shall not be converted into Unisource options.
The conversion of Alco options into Unisource options shall be made according to
the applicable formula set forth in Schedule 4.01 and shall be made consistent
with Section 424(a) of the Code with respect to options that are "incentive
stock options" under Section 422 of the Code.  The Unisource options shall have
vesting and other terms identical to those of the Alco options that they
replace, except that, for the period after the Effective Date, service with the
Unisource Group shall be considered continued service with the employer.

     (b) Alco shall adjust all outstanding options to purchase Alco Common Stock
that were granted under the Alco Group's stock option plans and that are held by
persons who are not Active Unisource Employees or Unisource Directors, or that
are held by Active Unisource Employees who retain their Alco options under
subsection (a) above, to take into account the Distribution.  The adjustment
shall be made according to the applicable formula set forth in Schedule 4.01 and
shall be made consistent with Section 424(a) of the Code with respect to


                                      17

 
options that are "incentive stock options" under Section 422 of the Code.

Plan (the "Alco PSPP") with respect to Active Unisource Employees (which term
shall include, for purposes of the PSPP only, any Unisource consultants
participating in the PSPP) and Unisource Directors.  The accounts of Active
Unisource Employees and Unisource Directors under the Alco PSPP shall be
transferred to the Unisource PSPP within 30 days after the Effective Date.  Any
unvested shares held for Active Unisource Employees and Unisource Directors
shall continue to vest in accordance with the existing vesting schedules, which
shall take into account service with the Unisource Group as continued service
for the period after the Effective Date.  Alco shall remain responsible for any
Alco PSPP benefits payable to Former Unisource Employees.

     (b) Unisource shall allow each eligible Active Unisource Employee and
Unisource Director to direct that the shares of Alco Common Stock held in his or
her account under the Unisource PSPP be converted into shares of Unisource
Common Stock.  The conversions into Unisource shares shall be made by exchanging
shares of Alco Common Stock for shares of Unisource Common Stock based on the
closing price of Alco Common Stock and Unisource Common Stock, respectively, as
of the last business day of the month in which the


                                      18

 
Active Unisource Employee or Unisource Director elects to have Alco shares
converted into Unisource shares.

     (c) Alco shall allow each of its eligible employees, directors and
consultants who remain with the Alco Group to direct that the shares of
Unisource Common Stock held in his or her account under the Alco PSPP be
converted into shares of Alco Common Stock.  The conversions into Alco shares
shall be made by exchanging shares of Unisource Common Stock for shares of Alco
Common Stock based on the closing price of Alco Common Stock and Unisource
Common Stock, respectively, as of the last business day of the month in which
the employee, director or consultant elects to have Unisource shares converted
into Alco shares.

     (d) Unisource and Alco each agree to purchase or sell such shares of
Unisource Common Stock or Alco Common Stock, respectively, as may be necessary
to effect the conversions described in subsections (b) and (c), at the prices at
which the exchanges of shares are to be made.

                    --------------------                                   
program for its eligible employees designated by Unisource as partners (the
"Unisource Loan Program"). All existing loans for Active Unisource Employees
under Alco's Partner Loan Program, and the related collateral, shall be
transferred to the Unisource Loan Program as soon as administratively
practicable after the Effective Date, and Unisource shall assume all rights and
responsibilities with respect to such loans.  Active Unisource Employees shall
be given an opportunity to substitute shares of Unisource Common Stock for
shares of Alco Common Stock as collateral for their loans, and continuing Alco
employees shall be given an opportunity to substitute shares of Alco Common
Stock for shares of Unisource Common Stock as collateral for their loans under

Active Unisource Employees for periods beginning on and after October 1, 1996.

     (b) Unisource shall establish a long-term incentive plan (the "Unisource

liability for all amounts payable under Alco's Long-Term Incentive Compensation
Plan ("the Alco LTIP") to Active Unisource Employees with respect to periods
ending on or after October 1, 1996.  The outstanding Alco LTIP awards for Active
Unisource Employees shall be paid under the Unisource LTIP.  The outstanding
Alco LTIP awards for Active Unisource Employees for the 1995-97 plan period
shall be paid in the form of Unisource Common Stock.  Unisource shall make such
adjustments to the financial goals, targets, payments and forms of payment as
Unisource deems appropriate to take into account the Distribution.

     (c) Alco shall remain responsible for any amounts payable under Alco bonus
plans or the Alco LTIP with respect to periods ending before October 1, 1996.

     Section 6.02.  Deferred Compensation Plans.

     (b) Alco shall retain all liabilities with respect to Alco's 1980 Deferred
Compensation Plan (the "1980 Plan"), and Alco shall pay all benefits to or with
respect to Active or Former Unisource Employees as required by the terms of the
1980 Plan.  Service with the Unisource Group after the Effective Date shall be
considered continued service with the employer for purposes of vesting and
payment of benefits under the 1980 Plan.  Alco shall retain all insurance
policies purchased by Alco in connection with the 1980 Plan, and Unisource shall
have no liability with respect to the 1980 Plan.

     (c) Unisource shall pay all benefits to or with respect to Active or Former
Unisource Employees (other than employees described in subsection (g) below)
under Alco's 1985 Deferred Compensation Plan (the "1985 Plan") as the benefits
become due.  Alco shall reimburse Unisource for the cost (as defined in
subsection (h) below) of each benefit payment made by Unisource under the 1985
Plan.  Service with the Unisource Group after the Effective Date shall be
considered continued service with the employer for purposes of vesting and
payment of benefits under the 1985 Plan.  Alco shall retain all insurance
policies purchased by Alco in connection with the 1985 Plan.

     (d) (i)  Active Unisource Employees shall cease deferrals under Alco's
1991 Deferred Compensation Plan (the "1991 Plan") as of the Effective Date.  The
retirement benefit of any Active Unisource Employee who is making deferrals
under the 1991 Plan immediately before the Effective Date shall be computed as a
pro rata portion (based on deferrals actually made) of the retirement benefit
that would have been payable had the Active Unisource Employee's deferrals
continued to the end of the applicable deferral period.  The pro rata portion
for a participant who has made deferrals based on a ten-year deferral period
since the inception of

                                      21

 
the 1991 Plan through December 31, 1996 shall be 73% of the participant's
retirement benefit under the 1991 Plan.  Service with the Unisource Group after
the Effective Date shall be considered continued service with the employer for
purposes of  vesting and payment of benefits under the 1991 Plan.  Each Active
or Former Unisource Employee who has a benefit under the 1991 Plan shall
continue to pay Alco the monthly payment for the cost of life insurance benefits
under the 1991 Plan, as required by the 1991 Plan, until the Active or Former
Unisource Employee attains age 65 or retires from the Unisource Group, whichever
occurs later.

          (ii) Unisource shall pay all benefits to or with respect to Active or
Former Unisource Employees (other than employees described in subsection (g)
below) under the 1991 Plan as the benefits become due.  Alco shall reimburse
Unisource for the cost (as described in subsection (h) below) of each benefit
payment made by Unisource under the 1991 Plan.  Alco shall retain all insurance
policies purchased by Alco in connection with the 1991 Plan, except as provided
below.

          (iii)  When an Active or Former Unisource Employee (other than an
employee described in subsection (g) below) attains age 65 or retires from the
Unisource Group, whichever occurs later, Alco shall transfer to Unisource, and
Unisource shall immediately transfer to the Active or Former Unisource Employee,
a life insurance policy that is attributable to the life insurance benefit under
the split-dollar arrangement of the 1991 Plan. Alco shall not transfer any
insurance policies relating to the retirement benefits under the 1991 Plan. If
for any reason Unisource is not able to transfer such life insurance policy
immediately to the Active or Former Unisource Employee, Alco shall transfer the
policy directly to the Active or Former Unisource Employee pursuant to the terms
of the 1991 Plan. Any tax benefit received by

                                      22

 
Unisource as a result of the transfer of a life insurance policy to an Active or
Former Unisource Employee shall be a credit against, and shall reduce, any
reimbursements that are to be made by Alco to Unisource with respect to benefits
paid by Unisource under the 1991 Plan or under other deferred compensation plans
pursuant to this Section 6.02.

     (e) Active Unisource Employees shall cease deferrals under Alco's 1994
Deferred Compensation Plan (the "1994 Plan") as of the Effective Date.  The
retirement benefit of an Active or Former Unisource Employee under the 1994 Plan
shall be computed based on the Active or Former Unisource Employee's deferrals
made before the Effective Date, adjusted by future hypothetical investment
performance pursuant to the 1994 Plan.  Service with the Unisource Group after
the Effective Date shall be considered service with the employer for purposes of
vesting and payment of benefits under the 1994 Plan.  Unisource shall pay all
benefits to or with respect to Active or Former Unisource Employees (other than
employees described in subsection (g) below) under the 1994 Plan as the benefits
become due.  Alco shall reimburse Unisource for the cost (as described in
subsection (h) below) of each benefit payment by Unisource under the 1994 Plan.
Alco shall retain all insurance policies purchased by Alco in connection with
the 1994 Plan.

     (f) Active Unisource Employees shall cease deferrals under Alco's 1996
Executive Deferred Compensation Plan (the "1996 Plan") as of the Effective Date.
Alco shall retain all liabilities with respect to the 1996 Plan and shall pay
all benefits to or with respect to Active or Former Unisource Employees as
required by the 1996 Plan.  Alco shall retain all insurance policies purchased
by Alco in connection with the 1996 Plan, and Unisource shall have no liability
with respect to the 1996 Plan.

                                      23

 
     (g) Notwithstanding the foregoing, Unisource shall have no responsibility
or liability with respect to benefits under the 1985 Plan, 1991 Plan and 1994
Plan for Active or Former Unisource Employees who were corporate staff employees
of the Alco Group or were otherwise on the Alco Group payroll when the deferrals
under the applicable Plan were made, and Alco shall remain responsible for
providing such benefits.

     (h) Alco shall reimburse Unisource for 63% of each benefit payment made by
Unisource under the 1985 Plan, 1991 Plan and 1994 Plan.  All reimbursements by
Alco to Unisource under this Section 6.02 shall be made within 30 business days
after Unisource delivers to Alco written notice of a payment by Unisource under
the 1985 Plan, 1991 Plan or 1994 Plan, as the case may be.

     (i) In order to enable Unisource to make benefit payments pursuant to this
Section 6.02, Alco shall provide Unisource with a list of all Active and Former
Unisource Employees participating in the 1985 Plan, 1991 Plan and 1994 Plan, the
amount of benefits payable to or with respect to each such Active or Former
Unisource Employee, and the dates on which such benefits are to be paid.

continue for the duration of that period of hospital confinement; costs for all
services provided during that period of hospital confinement shall be included
in the claim.  A long-term disability claim or life insurance disability claim
shall be deemed to have been incurred on the date the condition causing the
disability rendered the employee disabled, as determined by the committee or
plan administrator making the determination; costs for all long-term disability
benefits relating to the claim shall be included in the claim.

     (d) Unisource shall maintain its welfare benefit plans as a continuation of
Alco's welfare benefit plans.  Unisource shall give Active Unisource Employees
credit under its welfare benefit plans for payments made under Alco's welfare
benefit plans for purposes of deductibles and maximum out-of-pocket limits, and
Unisource shall not impose break in service or preexisting condition
requirements with respect to Active Unisource Employees' initial participation
in the Unisource welfare benefit plans.  Elections made by Active Unisource
Employees under Alco's welfare benefit plans shall continue in effect for
Unisource's corresponding plans, except to the extent that Unisource determines
otherwise.

                                      26

 
     (e) For purposes of allowing Alco to determine health care continuation
requirement obligations under the Code and ERISA, Unisource agrees to provide
such health care information as is required by Alco with respect to the volume
and level of coverage under health care plans.  Unisource shall be liable for
any health care continuation obligations under Section 4980B of the Code and
Section 601 through 608 of ERISA with respect to Active and Former Unisource
Employees and persons who are "qualified beneficiaries" (as that term is used in
Section 4980B of the Code) of such employees, to the same extent as Unisource is
liable for the underlying health care coverage of the Active or Former Unisource
Employees pursuant to subsection (b) above.

     (f) Unisource shall establish a long-term disability plan covering eligible
Unisource Employees who are participants in Alco's long-term disability plan,
and a trust meeting the requirements of Section 501(c)(9) of the Code to hold
assets of the Unisource LTD Plan.  Pursuant to subsection (b) above, Unisource
and its long-term disability plan shall be liable for any long-term disability
claims that are incurred on or after October 1, 1996 with respect to Active
Unisource Employees.

     (g) The Distribution shall not be considered an event entitling any
employee to salary continuation or other severance benefits.  Notwithstanding
subsection (b), Unisource shall assume liability for all salary continuation and
other severance benefits that payable on or after the Effective Date with
respect to all Active Unisource Employees.

     Section 6.04.  Monthly Investment Plan.  Unisource shall establish a
                    -----------------------                              
monthly investment plan for eligible Active Unisource Employees upon such terms
as Unisource deems appropriate.

     Section 6.05.  Vacation Pay and Similar Items.  Unisource shall assume or
                    ------------------------------                            
retain liability for all unpaid vacation pay, sick pay and personal leave
accrued by Active Unisource Employees as of the Effective Date.

     Section 6.06.  Canadian Plans.  Unisource shall continue to be responsible
                    --------------                                             
for the Pension Plan for Employees of the Canadian Subsidiary and Associated
Companies of Alco Standard Corporation and the welfare and other employee
benefit plans that cover Canadian employees of the Unisource Group.

                                DIRECTORS PLANS

     Section 7.01.  Stock Options.
                    ------------- 
     (a) Unisource shall establish such stock option plans as it deems
appropriate for Unisource Directors.  Unisource and Alco shall give each
Unisource Director an opportunity to elect, by December 6, 1996, either:

          (i) To have part or all of the Unisource Director's outstanding
     options to purchase Alco Common Stock that were granted under Alco's
     directors stock option plans converted into options to purchase Unisource
     Common Stock, or

          (ii) To retain the Unisource Director's options to purchase Alco
     Common Stock that were granted under Alco's directors stock option plans.

If a Unisource Director fails to make an election, his or her Alco options shall
not be converted into Unisource options.  The conversion shall be made according
to the applicable formula set forth in Schedule 4.01.  The Unisource options
shall have vesting and other terms identical to

                                      28

 
those of the Alco options that they replace, except that, for the period after
the Effective Date, service as a director of Unisource shall be considered
continued service.

     (b) Alco shall adjust all outstanding options to purchase Alco Common Stock
that are held by Alco directors who do not become Unisource Directors, or that
are held by Unisource Directors who retain their Alco options under subsection
(a) above, and that were granted under Alco's directors stock option plans, to
take into account the Distribution.  The adjustment shall be made according to
the applicable formula set forth in Schedule 4.01.

     Section 7.02.  Retirement Plan.  As of the Effective Date, Unisource shall
                    ---------------                                            
establish a retirement plan for its outside directors (the "Unisource Directors
Plan") that is comparable to Alco's Retirement Plan for Non-Employee Directors
(the "Alco Directors Plan"). Unisource shall assume liability for all benefits
that Unisource Directors accrued under the Alco Directors Plan before the
Effective Date, and such benefits shall be provided under the Unisource
Directors Plan.  The Unisource Directors Plan shall be a continuation of the
Alco Directors Plan, and service as a director of Alco before the Effective Date
shall be taken into account in computing benefits under the Unisource Directors
Plan.  Alco shall have no liability with respect to the Unisource Directors
Plan.

                                 ARTICLE VIII
                                INDEMNIFICATION

     Section 8.01.  Unisource Indemnification of the Alco Group.  On and after
                    -------------------------------------------               
the Effective Date, Unisource shall indemnify, defend and hold harmless each
member of the Alco Group, and each of their respective directors, officers,
employees and agents (the "Alco Indemnitees") from and against any and all
damage, loss, liability and expense (including,

                                      29

 
without limitation, reasonable expenses of investigation and reasonable
attorneys fees and expenses in connection with any and all Actions or threatened
Actions) (collectively, "Indemnifiable Losses") incurred or suffered by any of
the Alco Indemnitees and arising out of, or due to the failure of Unisource or
any member of the Unisource Group to pay, perform or otherwise discharge, any of
the employee benefit liabilities and obligations assumed or retained, and
agreements made, by Unisource pursuant to this Agreement.

     Section 8.02.   Alco Indemnification of Unisource Group.  On and after the
                     ---------------------------------------                   
Effective Date, Alco shall indemnify, defend and hold harmless each member of
the Unisource Group, and each of their respective directors, officers, employees
and agents (the "Unisource Indemnitees") from and against any and all
Indemnifiable Losses incurred or suffered by any of the Unisource Indemnitees
and arising out of, or due to the failure of Alco or any member of the Alco
Group to pay, perform or otherwise discharge, any of the employee benefit
liabilities and obligations assumed or retained, and agreements made, by Alco
pursuant to this Agreement.

     Section 8.03.   Insurance and Third Party Obligations.  No insurer or any
                     -------------------------------------                    
other third party shall be (a) entitled to a benefit it would not be entitled to
receive in the absence of the foregoing indemnification provisions, (b) relieved
of the responsibility to pay any claims to which it is obligated or (c) entitled
to any subrogation rights with respect to any obligation hereunder.

                                  ARTICLE IX
                           INDEMNIFICATION PROCEDURES

     Section 9.01.   Notice and Payment of Claims.  If any Alco or Unisource
                     ----------------------------                           
Indemnitee (the Indemnified Party") determines that it is or may be entitled to
indemnification by a party (the "Indemnifying Party") under Article VIII (other
than in connection with any Action or claim subject to Section 9.02), the
Indemnified Party shall deliver to the Indemnifying Party a written notice
specifying, to the extent reasonably practicable, the basis for its claim for
indemnification and the amount for which the Indemnified Party reasonably
believes it is entitled to be indemnified.  After the Indemnifying Party shall
been notified of the amount for which the Indemnified Party seeks
indemnification, the Indemnifying Party shall, within 90 days after receipt of
such notice, pay the Indemnified Party such amount in cash or other immediately
available funds (or reach agreement with the Indemnified Party as to a mutually
agreeable alternative payment schedule) unless the Indemnifying Party objects to
the claim for indemnification or the amount thereof.  If the Indemnifying Party
does not give the Indemnified Party written notice objecting to such claim and
setting forth the grounds therefor within the same 90 day period, the
Indemnifying Party shall be deemed to have acknowledged its liability for such
claim and the Indemnified Party may exercise any and all of its rights under
applicable law to collect such amount.

     Section 9.02.  Notice and Defense of Third-Party Claims.  Promptly
                    ----------------------------------------           
following the earlier of (a) receipt of notice of the commencement by a third
party of any Action against or otherwise involving any Indemnified Party or (b)
receipt of information from a third party alleging the existence of a claim
against an Indemnified Party, in either case, with respect to

                                      31

 
which indemnification may be sought pursuant to this Agreement (a "Third-Party
Claim"), the Indemnified Party shall give the Indemnifying Party written notice
thereof.  The failure of the Indemnified Party to give notice as provided in
this Section 9.02 shall not relieve the Indemnifying Party of its obligations
under this Agreement, except to the extent that the Indemnifying Party is
prejudiced by such failure to give notice.  Within 90 days after receipt of such
notice, the Indemnifying Party may (a) by giving written notice thereof to the
Indemnified Party, acknowledge liability for and at its option elect to assume
the defense of such Third-Party Claim at its sole cost and expense or (b) object
to the claim of indemnification set forth in the notice delivered by the
Indemnified Party pursuant to the first sentence of this Section 9.02; provided
that if the Indemnifying Party does not within the same 90 day period give the
Indemnified Party written notice objecting to such claim and setting forth the
grounds therefor or electing to assume the defense, the Indemnifying Party shall
be deemed to have acknowledged its liability for such Third-Party Claim.  Any
contest of a Third Party Claim as to which the Indemnifying Party has elected to
assume the defense shall be conducted by attorneys employed by the Indemnifying
Party and reasonably satisfactory to the Indemnified Party;  provided that the
Indemnified Party shall have the right to participate in such proceedings and to
be represented by attorneys of its own choosing at the Indemnified Party's sole
cost and expense.  If the Indemnifying Party assumes the defense of the Third-
Party Claim, the Indemnifying Party may settle or compromise the claim without
the prior written consent of the Indemnified Party; provided that the
Indemnifying Party may not agree to any such settlement pursuant to which any
such remedy or relief, other than monetary damages for which the Indemnifying
Party shall be responsible hereunder, shall be applied to or against the
Indemnified Party, without the prior

                                      32

 
written consent of the Indemnified Party, which consent shall not be
unreasonably withheld.  If the Indemnifying Party does not assume the defense of
a Third-Party Claim for which it has acknowledged liability for indemnification
under Article VIII, the Indemnified Party may require the Indemnifying Party to
reimburse it on a current basis for its reasonable expenses of investigation,
reasonable attorney's fees and reasonable out-of-pocket expenses incurred in
defending against such Third-Party Claim and the Indemnifying Party shall be
bound by the result obtained with respect thereto by the Indemnified Party;
provided that the Indemnifying Party shall not be liable for any settlement
effected without its consent, which consent shall not be unreasonably withheld.
The Indemnifying Party shall pay to the Indemnified Party in cash the amount for
which the Indemnified Party is entitled to be indemnified (if any) within 15
days after the final resolution of such Third-Party Claim (whether by the final
nonappealable judgment of a court of competent jurisdiction or otherwise) or, in
the case of any Third-Party Claim as to which the Indemnifying Party has not
acknowledged liability, with 15 days after such Indemnifying Party's objection
has been resolved by settlement, compromise or the final nonappealable judgment
of a court of competent jurisdiction.

Agreement shall be in writing and any communications or delivery hereunder shall

                      --------------------                                    
or amended, nor may rights hereunder be waived, except by an instrument in
writing executed by the party or parties to be charged with such amendment or
waiver.  No waiver of any terms, provision or condition of  or failure to
exercise or delay in exercising any rights or remedies under this Agreement, in
any one or more instances, shall be deemed to be, or construed as, a further or
continuing waiver of any such term, provision, condition, right or remedy or as
a waiver of any other term, provision or condition of this Agreement.

     Section 10.03.   Entire Agreement.  This Agreement, together with the
                      ----------------                                    
Distribution Agreement and the Ancillary Agreements referred to therein,
constitute the entire understanding of the parties hereto with respect to the
subject matter hereof, superseding all negotiations, prior discussions and prior
agreements and understandings relating to such subject matter.  To the extent
that the provisions of this Agreement are inconsistent with the provisions of
the Distribution Agreement or any Ancillary Agreement, the provisions of this
Agreement

                                      34

 
shall prevail.

     Section 10.04.   Parties in Interest.  Neither of the parties hereto may
                      -------------------                                    
assign its rights or delegate any of its duties under this Agreement without the
prior written consent of each other party.  This Agreement shall be binding
upon, and shall inure to the benefit of, the parties hereto and their respective
successors and permitted assigns.  Nothing contained in this Agreement, express
or implied, is intended to confer any benefits, rights or remedies upon any
person or entity other than members of the Alco Group and the Unisource Group,
and the Alco Indemnitees and Unisource Indemnitees under Articles VIII and IX
hereof.

     Section 10.05.   Further Assurances and Consents.  In addition to the
                      -------------------------------                     
actions specifically provided for elsewhere in this Agreement, each of the
parties hereto will use its reasonable efforts to (i) execute and deliver such
further instruments and documents and take such other actions as any other party
may reasonably request in order to effectuate the purposes of this Agreement and
to carry out the terms hereof and (ii) take, or cause to be taken, all actions,
and to do, or cause to be done, all things, reasonably necessary, proper or
advisable under applicable laws, regulations and agreements or otherwise to
consummate and make effective the transactions contemplated by this Agreement,
including, without limitation, using its reasonable efforts to obtain any
consents and approvals and to make any filings and applications necessary or
desirable in order to consummate the transactions contemplated by this
Agreement;  provided that no party hereto shall be obligated to pay any
consideration therefor (except for filing fees and other similar charges) to any
third party from whom such consents, approvals and amendments are requested or
to take any action or omit to take any action if the taking of or the omission
to take such action would be unreasonably burdensome to the party or its Group
or the business

                                      35

 
thereof. To the extent that either party is obligated to deliver shares of the
other party in satisfaction of obligations under employee or director benefit
plans or other arrangements, including, without limitation, savings plans, stock
option plans, stock purchase plans and bonus and incentive plans, the party
whose shares are required for such purpose shall make such shares available from
authorized but unissued shares or treasury shares on such terms as may be
appropriate to the transaction.

     Section 10.06.   Severability.  The provisions of this Agreement are
                      ------------                                       
severable and should any provision hereof be void, voidable or unenforceable
under any applicable law, such provision shall not affect or invalidate any
other provision of this Agreement, which shall continue to govern the relative
rights and duties of the parties as though such void, voidable or unenforceable
provision were not part hereof.

     Section 10.07.  Governing Law.  This Agreement shall be construed in
                     -------------                                       
accordance with, and governed by, the laws of the Commonwealth of Pennsylvania,
without regard to the conflicts of law rules of such state.

     Section 10.08.   Counterparts.  This Agreement may be executed in one or
                      ------------                                           
more counterparts each of which shall be deemed an original instrument, but all
of which together shall constitute but one and the same Agreement.

     Section 10.09.   Disputes.  Resolution of any and all disputes arising from
                      --------                                                  
or in connection with this Agreement, whether based on contract, tort, statute
or otherwise, including, but not limited to, disputes in connection with claims
by third parties shall be exclusively governed by and settled in accordance with
provisions identical to those set forth in Section 12.11 of the Distribution
Agreement, which Section is hereby incorporated by this reference.

                                      36

 
     IN WITNESS WHEREOF, the parties hereto have executed and delivered this
Agreement as of the day and year first above written.
