           -----------                                                     
supplement the annual pension under the Master Plan of a Participant who attains

will also supplement a pre-retirement death benefit payable under the Master
Plan on behalf of a Participant who dies with a vested interest in the Master
Plan while employed by the Company.

     3.02 Amount.  The amount of the supplement for a Participant described in
          ------                                                              
Section 2.11(a) shall be (a) the difference, if any, between the pension or pre-
retirement death benefit paid under the Master Plan and the pension or pre-
retirement death benefit which would have been payable under the Master Plan if
(i) the provisions of the Master Plan were administered without regard to the
Annual Benefit Limit, (ii) the Participant's Compensation had not been limited

the Participant's Compensation for purposes of the Master Plan had not been
reduced in connection with a Deferred Compensation Plan, or (b) such other
amount as determined by Unisource.  Notwithstanding the foregoing, the amount of
the supplement for a Participant described in Section 2.11(b) shall be the
amount as determined by Unisource.

          ----------------                                                      
or pre-retirement death benefits will be paid in the same form as the payment of
pension and pre-retirement death benefits under the Master Plan. Notwithstanding
the foregoing, the Committee reserves the right to convert any supplemental
pension or pre-retirement death benefits into an actuarially equivalent form of
payment as determined by the Committee with the advice of the actuary for the
Master Plan.

     3.04 Commencement of Benefits.  A Participant or Beneficiary shall begin to
          ------------------------                                              
receive supplemental pension or pre-retirement death benefits, as the case may
be, as of the same time that benefits begin to be paid under the Master Plan, or
such other time as determined by Unisource.  Actual benefit payments shall be
made at the same time as the Master Plan payments are made.


     3.05 Approval of Committee.  Notwithstanding the provisions of 
          ---------------------                                    
Sections 3.03 and 3.04 above, an election made by a Participant or Beneficiary
under the Master Plan with respect to the form of benefit payment under the
Master Plan, or the date for commencement of payment thereof, shall not be
effective with respect to the form of payment or date for commencement of
payment of benefits hereunder unless such election is expressly approved in
writing by the Committee with respect to benefits under this Plan. If the
Committee shall disapprove such election in writing, then the form of payment or
date for commencement of payment shall be selected by the Committee in its sole
discretion.

     3.06 Method of Calculation.  All calculations of benefits under this Plan
          ---------------------                                               
shall be in accordance with the methods and assumptions utilized by the Master
Plan.

     3.07 Qualified Domestic Relations Order.  In the event a Participant's
          ----------------------------------                               
pension or 

                                       3

 
pre-retirement death benefit under the Master Plan is subject to a qualified
domestic relations order as defined in section 414(p) of the Code, the
supplemental pension or pre-retirement death benefit provided by this Plan shall
be calculated and paid as if no qualified domestic relations order was in
existence.

      3.08  Coordination with Alco Supplemental Plan.  All benefits that
            ----------------------------------------                    
Participants in this Plan accrued before January 1, 1997 under the Alco
Supplemental Plan shall be provided to such Participants under the terms of this
Plan, and the provisions of this Article III shall include such benefits.  There
shall be no duplications of benefits under this Plan and the Alco Supplemental
Plan.  If for any reason benefits are paid to a Participant under the Alco
Supplemental Plan with respect to benefits accrued before January 1, 1997, any
benefits payable under this Plan shall be reduced by the amount paid to the
Participant under the Alco Supplemental Plan.

IV.   Vesting.
      ------- 

A Participant shall have a right to a benefit under this Plan only if and to the
extent that (a) the Participant has a vested right to a benefit under the Master
Plan and (b) the Participant has met the other requirements set forth in this
Plan pertaining to the right to receive a Plan benefit.

V.    Forfeiture.
      ---------- 

A Participant and his Beneficiary shall not be entitled to receive any benefits
under this Plan if the Participant engages in any conduct which, in the
reasonable opinion of the Board of Directors of Unisource, is detrimental to the
best interests of a Company. Such conduct shall include accepting employment
with a competitor of a Company within a period of time following termination of
employment and in a geographic area that the Unisource board of directors deems
reasonable.

VI.   Facility of Payment.
      ------------------- 

In the event that the Administrator finds that any Participant or Beneficiary to
whom a benefit is payable hereunder is unable to care for his or her affairs
because of physical, mental, or legal incompetence, any payment due hereunder
may (unless prior claim therefor shall have been made by a duly qualified
guardian or other legal representative), in the discretion of the Administrator,
be paid to the person or institution deemed by the Administrator to be
maintaining or responsible for the maintenance of such Participant or
Beneficiary; any such payment shall be deemed a payment for the account of the
Participant or Beneficiary and shall constitute a complete discharge of any
liability therefor under the Plan.

VII.  Withholding.
      ----------- 

Unisource shall withhold from payments made under the Plan any federal, state or
local 

                                       4

 
taxes required to be withheld from a Participant's wages.

VIII.    Source of Funds.
         --------------- 

This Plan shall be unfunded, and payment of benefits hereunder shall be made
from the general assets of Unisource.  Any asset which may be set aside,
earmarked or identified as being intended for the provision of benefits
hereunder shall remain an asset of Unisource and shall be subject to the claims
of its general creditors.  Each Participant shall be a general creditor of
Unisource to the extent of the value of his or her benefit accrued hereunder,
but the Participant shall have no right, title, or interest in any specific
asset that Unisource may set aside or designate as intended to be applied to the
payment of benefits under this Plan.  Unisource's obligations under the Plan
shall represent an unfunded and unsecured promise of Unisource to pay money in
the future.

IX. Nonalienation of Benefits.
    ------------------------- 

Except as hereinafter provided with respect to marital disputes, neither
benefits or rights of a Participant or any Beneficiary shall be subject to the
claim of any creditor. In particular, to the fullest extent permitted by law,
all of such benefits and rights shall be free from attachment, garnishment or
any other legal or equitable process available to any creditor of the
Participant or the Beneficiary. Neither the Participant nor the Beneficiary
shall have the right to alienate, anticipate, commute, pledge, encumber, or
assign any of the benefits or payments which he or she may expect to receive,
contingently or otherwise, under this Plan, except the right to designate a
Beneficiary. In cases of marital dispute, Unisource will observe the terms of
the Plan unless and until ordered to do otherwise by a state or federal court,
whether such order effects a judgment of such court or is issued to enforce a
judgment or order of another court.

X.  Adverse Determinations.
    ---------------------- 

    10.01     Claim for Benefits.  If at any time the Administrator makes a
              ------------------                                           
determination adverse to a  Participant or any other claimant with respect to a
written claim for benefits or participation under the Plan, the Administrator
shall notify the claimant in writing of such determination setting forth:

              (a)  the specific reason therefor;

              (b) the reference to the specific provision or provisions of the
Plan on which such determination is based;

              (c) a description of any additional material or information
necessary for the claimant to perfect the claim and an explanation of why such
material or information is necessary; and

              (d) an explanation of the rights and procedures set forth in
Section 10.02.


                                       5

 
     The Administrator's decision shall be forwarded to the claimant within 90
days of the Administrator's receipt of the claim; provided, however, that in
special circumstances the Administrator may extend the response period for up to
an additional 90 days, provided that the Administrator so notifies the claimant
in writing and specifies the reason or reasons for such extensions.

     10.02     Review of Claim.  A Participant or any other claimant who
               ---------------                                          
receives notice of an adverse determination by the Administrator with respect to
his claim may himself or through his duly authorized representative:

               (a) request in writing within 60 days of receipt of such notice a
     review of the Administrator's determination by the Committee;

               (b) review pertinent documents; and

               (c) submit issues and comments with respect to the controversy in
     writing to the Committee. 



     The Committee shall render a decision within 60 days of receipt of a
request for review, which decision shall be in writing and shall set forth the
specific reasons for the decision reached and the specific provisions of the
Plan on which the decision is based.  The Committee may extend the 60 day
response period in special circumstances for up to an additional 60 days.
Written notice of the extension shall be sent to the claimant prior to the
commencement of the extension.  A copy of such decision shall be delivered to
the Participant and maintained in the records of the Committee.

XI.      Amendment and Termination.
         ------------------------- 

Unisource's Board of Directors reserves the right to amend this Plan at any time
and from time to time in any fashion, and to terminate it at will.  No amendment
or termination of the Plan shall decrease or restrict any vested benefit which a
Participant (or Beneficiary) has accrued under the Plan, as of the date of
termination or amendment of the Plan based on the Participant's accrued benefit
under the Master Plan at such date, unless the Participant (or Beneficiary)
would have been entitled to a smaller Plan benefit if the Plan had not been
amended or terminated.

XII.     No Contract of Employment.
         ------------------------- 

Nothing contained herein shall be construed as conferring upon any person the
right to be employed or continue in the employ of the Company.

XIII.    Applicable Law.
         -------------- 

The provisions of this Plan shall be construed and interpreted according to the
laws of the Commonwealth of Pennsylvania to the extent not superseded by federal
law.

XIV.     Successors.
         ---------- 

The provisions of this Plan shall bind and inure to the benefit of Unisource and
its successors and assigns.  The term successors as used herein shall include
