           Beneficiary will be equal to the excess of:

           (a) The benefits which would have been paid to the Participant or his
               Beneficiary under the Applicable Sun Retirement Plan, if the
               provisions of that plan were administered:

               (i) without regard to the Statutory Limitations, and

               (ii)    so that the compensation used for benefit accrual
                       purposes under the Applicable Sun Retirement Plan was
                       increased to reflect Restricted Stock Unit income, over

           (b) The benefits payable to the Participant or his Beneficiary under
               the Applicable Sun Retirement Plan.

    3.01A  ADJUSTMENTS TO RETIREMENT BENEFITS SUBSEQUENT TO CERTAIN CONTROL
           TRANSACTIONS. (a) If, subsequent to a Control Transaction which has
           not been expressly approved by at least a majority vote of the
           Continuing Directors, there is

 
           a Change in Control and the Employer thereafter takes action or omits
           to take action which will result in either a complete or partial
           termination of the Plan, then:

               (i) effective immediately prior to a complete termination of the
                   Plan, there shall be an increase in the benefits originally
                   calculated under Section 3.01 by an amount equal to three
                   percent (3%) per year reduced by any prior retiree benefit
                   adjustments to such benefits, compounded annually, for a
                   period of fifteen (15) years, for the benefit of active
                   Participants, Participants who retired on or after December
                   31, 1990 and each surviving Spouse of a Participant who was
                   entitled to pre- or post-retirement Spouse's benefits. Such
                   benefit increases shall be calculated immediately upon the
                   termination of the Plan, regardless of whether the payment of
                   such benefits has commenced;

               (ii) effective immediately prior to a partial termination of the
                    Plan, the benefit increases set forth in Section 3.01A(a)(i)
                    above shall be provided to the affected Participants.

           (b) If, subsequent to a Control Transaction which has not been
               expressly approved by at least a majority vote of the Continuing
               Directors, there is a Change in Control, then this Section 3.01A
               shall be irrevocable, shall apply to successor Plans and cannot
               be amended or modified at any time.

     3.02  NORMAL FORM OF PAYMENT. Except as otherwise provided in Article IV,
           retirement benefits under this Plan will be in the form of a lump sum
           payment of the Actuarial Equivalent of the benefit determined under
           Section 3.01.

     3.03  COMMENCEMENT OF PAYMENTS. A Participant's retirement income will
           commence on the same date as the commencement of benefits under the
           Applicable Sun Retirement Plan.

                      OPTIONAL FORMS OF RETIREMENT INCOME

     4.01  ELECTION OF AN OPTIONAL FORM OF PAYMENT. Not later than thirty (30)
           days prior to a Participant's retirement date a Participant may elect
           in lieu of the normal form of retirement income, an optional form of
           retirement income which is the Actuarial Equivalent of the monthly
           income determined under Section 3.01. A Participant may not change or
           revoke an elected option unless such change or revocation is made at
           least thirty (30) days prior to the Participant's

 
           retirement date. Each election, designation and revocation of an
           option will be made in writing and in conformity with such rules as
           may be prescribed by the Plan Administrator.

     4.02  OPTIONAL FORMS OF PAYMENT. A Participant may elect to receive an
           optional form of retirement income in the same form and manner as the
           Participant is receiving under the Applicable Sun Retirement Plan.

     4.03  ACCELERATION OF ANNUITY OPTIONS. Notwithstanding the foregoing, if
           the Internal Revenue Service makes a determination that the
           Participant must include any amounts from the Plan in his taxable
           income in a taxable year prior to the year in which the Participant
           actually receives those amounts, the Participant shall receive the
           Actuarial Equivalent of the remainder of his benefit determined under
           Section 4.02. Such distribution shall be made no later than the last
           day of the calendar year in which the Participant informs the Plan
           Administrator that the Internal Revenue Service has made such a
           determination.

           by action of the Board of Directors, to amend, alter, suspend or
           terminate the Plan in whole or in part, and at any time. However, if
           the Board of Directors should amend, alter, suspend or terminate the
           Plan, the Company will be liable for any benefits accrued under this
           Plan (determined on the basis of each employee's presumed termination
           of employment as of the date of such amendment, alteration,
           suspension or termination) as of the date of such action.

     6.02  ALIENATION OF BENEFITS. No benefits payable under the Plan will be
           subject in any manner to anticipation, alienation, sale, transfer,
           assignment, pledge, encumbrance or charge, and any action by way of
           anticipating, alienating, selling, transferring, assigning, pledging,
           encumbering or charging the same will be void and of no effect nor
           will any such benefit be in any manner liable for or subject to the
           debts, contracts, liabilities, engagements or torts of the person
           entitled to such benefit.

     6.03  PAYMENT TO MINORS AND INCOMPETENTS. If a Participant, Spouse,
           contingent annuitant or Beneficiary entitled to receive any benefits
           hereunder is a minor, or is deemed by the Plan Administrator or is
           adjudged to be legally incapable of giving a valid receipt and
           discharge for such benefits, they will be paid to the duly appointed
           guardian or committee of such minor or incompetent, or they may be
           paid to such person or persons who the Plan Administrator believes is
           or are caring for or supporting such minors or incompetents. Any such
           payments, to the extent thereof, will be a complete discharge for the
           payment of such benefit.

 
     6.04  UNCLAIMED BENEFITS. If any benefit under the Plan had been payable to
           and unclaimed by any person for a period of four years since the
           whereabouts or existence of such person was last known to the Plan
           Administrator, the Plan Administrator may direct that all rights of
           such person to payments accrued and to future payments be terminated
           absolutely, provided that if such person subsequently appears and
           identifies himself to the satisfaction of the Plan Administrator,
           then the liability will be reinstated.

     6.05  PLAN VOLUNTARY. The Plan is purely voluntary on the part of the
           Company. Neither the establishment of the Plan, nor any amendment
           thereto, nor the creation of any fund or account, nor the payment of
           any benefit will be construed as conferring upon any Employee or
           Participant the right to be retained in the employ of the Company or
           any Affiliated Company, and all Employees and Participants will
           remain subject to discharge, discipline or termination to the same
           extent as if the Plan had never been established.

     6.06  GENDER. Whenever used herein, the masculine pronoun will include the
           feminine and the singular the plural, unless a different meaning is
           plainly required by the context.

     6.07  CONSTRUCTION. The Plan will be construed, enforced and administered
           according to the laws of the Commonwealth of Pennsylvania to the
           extent not preempted by Federal law, which shall otherwise control.
           In the event any provision of the Plan is held illegal or invalid for
           any reason, it will not affect the remaining provisions of the Plan,
           but the Plan will be construed and enforced as if such illegal and
           invalid provision had not been included therein.
