or Regular Part-Time Employees of the Company.  Any employee who was previously
employed by the Company and is rehired shall be entitled to credit for any prior
period(s) of employment with the Company for the purpose of calculating Years of
Service referenced in Section 1.09 and Section 3.01, in the event that the

entitle the Employee to benefits under the Plan.  Any Employee who was

benefits under this Plan and is subsequently reemployed by the Company shall not
be entitled to receive credit for any prior period of employment for which
benefits have been paid under this Plan.

     2.02 Eligibility.
          ----------- 

          (a)  Except as otherwise provided in this Section 2.02 or Section 3 of
               this Plan, any Participant whose employment with the Company is
               terminated by the Company shall be eligible for benefits under
               the Appendix, Schedule 2, unless the termination is:

               (1)  because of the death or Disability of the Employee;
               (2)  by the Company for Cause (as defined in Subsection 2.03);
               (3)  by the Employee;
               (4)  by the Company in connection with the sale or transfer of a
                    plant, unit, division, or subsidiary of the Company to a
                    successor (whether by reason of a sale of stock or assets),
                    by means of which the Employee continues employment with the
                    successor organization or is offered employment with the
                    successor organization in essentially the same or a similar
                    position, with comparable compensation, within the same
                    geographical area, even if not at the same plant or office;
               (5)  by the Company and the employee was offered essentially the
                    same or a similar position, with comparable compensation,
                    within the 

                                      -2-

 
                    same geographical area, even if not at the same plant,
                    office or location.

          (b)  Any Participant who is involuntarily terminated, as determined by
               the Committee, due to a reduction in the workforce of the office
               or manufacturing location at which the Participant is employed,
               will be eligible for severance benefits set forth in the
               Appendix, Schedule 3 in lieu of benefits under Schedule 2,
               provided:  (1) the Participant is notified in writing before
               January 1, 1999, that (s)he will be terminated, and his or her
               employment ends before January 1, 2000; and (2)  the Participant
               is not otherwise excluded from receiving benefits under Paragraph
               (a) above. This benefit is provided out of concern for employees
               who lose their jobs during this time of significant technological
               change and restructuring of the work force.

          (c)  Any Participant who is involuntarily terminated, as determined by
               the Committee, due to a finding of the Executive Committee of the
               Board of Directors that the requirements of the Participant's
               position or position status have been fundamentally altered,
               including changes due to a lack of promotability, will be
               eligible for severance benefits set forth in the Appendix,
               Schedule 3 in lieu of benefits under Schedule 2, provided:  (1)
               the Participant is notified in writing before January 1, 1999,
               that (s)he will be terminated, and his or her employment ends
               before January 1, 2000; and (2)  the Participant is not otherwise
               excluded from receiving benefits under Paragraph (a) above. This
               benefit is provided out of concern for employees who lose their
               jobs because the requirements of their positions or their
               position status have been fundamentally altered due to economic
               conditions, or present or anticipated structural, procedural or
               technological change.

          (d)  Any Participant who is terminated by the Company for performance-
               related reasons after January 1, 1999, will be eligible for
               severance benefits as set forth in the Appendix, Schedule 1,
               provided that the Participant is not otherwise excluded from
               receiving benefits under Paragraph (a) or Section 3 of this Plan.
               This section is not intended to otherwise make benefits available
               to employees terminated by the Company for Cause (as defined in
               Subsection 2.03).

     2.03 Termination for Cause.  Termination of a Participant's employment for
          ---------------------                                                
Cause shall be deemed to have occurred if the Participant's employment is
terminated by the Company due to the Participant's deliberately engaging in
gross misconduct which is demonstrably and materially 

                                      -3-

 
injurious to the Company, monetarily or otherwise, including but not limited to
fraud or embezzlement by the Employee.

For purposes of this Section 2.03, no act, or failure to act, on the part of the
Participant shall be considered "deliberate" unless done, or omitted to be done,
by the Participant not in good faith and without reasonable belief that such
action or omission was in the best interests of the Company.

     2.04 Effect of Participant's Eligibility to Retire.  No eligible
          ---------------------------------------------              
Participant will be denied severance benefits solely because such Participant is
also eligible for retirement benefits under another plan of the Company.

     2.05 Reservation of Rights.  The Company reserves the right for the
          ---------------------                                         
Committee to depart from the Schedules listed in the Appendix where the eligible
Participant's attendance, job performance, or other job-related conduct appears
to the Company to justify an upward or downward adjustment in benefits.
However, in no event shall the maximum benefit payable under the Plan exceed
twice such Participant's annual compensation, as defined in 29 C.F.R. Section
2510.3-2(b)(2); nor shall the maximum payment period exceed 24 months after the
termination of the Participant's employment.

     2.06 Classification of Employees to Whom the Plan Does Not Relate.  The
          ------------------------------------------------------------      
severance policies and procedures contained in this Plan do not apply to
employees classified by the Company as temporary or hourly paid employees.

3.   BENEFITS

     3.01 Amount and Schedule of Benefit Payments.  The Company will provide
          ---------------------------------------                           
severance pay and benefits, as described in paragraphs (a) through (e) below, to
a Participant eligible for benefits under this Plan.

     (a)  Accrued Salary.  Any accrued salary not yet paid to the Participant
          --------------                                                     
          for services performed prior to the Date of Termination shall be paid
          in compliance with state law, but not later than 20 calendar days
          following the Date of Termination.

     (b)  Vacation Pay.  The Participant will be reimbursed for vacation pay to
          ------------                                                         
          the Date of Termination in accordance with Company policy.

     (c)  Severance Pay.  Effective January 1, 1998, except for Employees
          -------------                                                  
          notified in writing prior to that date, whose severance pay shall be
          calculated in the manner in effect prior to that date, the Participant
          shall be paid a severance payment related to the Participant's Years
          of Service and Earnings.  The amount of severance payment shall be
          calculated using the relevant Schedule of the Appendix as 

                                      -4-

 
          determined under Sections 2.02 and 2.05. Weeks of Severance for
          partial years of service will be calculated proportionately. A week's
          pay shall be the Earnings divided by 52.

     (d)  Mode of Payment.  After the eligible Participant has satisfied all
          ---------------                                                   
          conditions precedent to receive severance benefits, such benefits will
          be paid to the Participant by salary continuation until the severance
          allowance is exhausted, unless the Plan Administrator approves a lump
          sum payment or some combination of periodic or lump sum payments.

     (e)  Insurance Benefits.  An eligible Participant's insurance benefits
          ------------------                                               
          shall be determined in accordance with the applicable insurance
          benefit plan.

     3.02 Other Circumstances That Can Result in Disqualification, Forfeiture,
          --------------------------------------------------------------------
          Reduction or Suspension of Severance Benefits.
          --------------------------------------------- 

     (a)  Elective Deductions.  An eligible Participant may elect to have
          -------------------                                            
          insurance premiums for Company-sponsored insurance plans deducted from
          severance payments.

     (b)  Legally Required Deductions.  Appropriate federal, state and local
          ---------------------------                                       
          taxes will be withheld from all severance payments.

     (c)  Effect of Rehire or Reinstatement (Or An Offer of Same).  If an
          --------------------------------------------------------       
          eligible Participant is granted severance benefits and the Participant
          is either rehired or reinstated as a regular salaried employee on a
          regular full-time basis by the Company (or is offered rehire or
          reinstatement on a full-time basis by the Company) before the end of
          the pay continuation period, then the Participant forfeits any unpaid
          severance payments for the periods following rehire or reinstatement
          (or the date of offer of same).

     (d)  Effect of Sale of Portion of Business Assets.  Any Participant whose
          --------------------------------------------                        
          employment with the Company is terminated during or in anticipation of
          a sale of some, but not all, assets of the Company is not entitled to
          severance benefits if the purchaser of such assets offers to employ
          the Participant for substantially the same or greater compensation as
          the Participant was receiving immediately prior to the Date of
          Termination, and such offer of employment is made by the purchaser
          within no later than eight (8) weeks after the termination of the
          Participant's employment by the Company.

     (e)  Effect of Participant Misconduct.  Any Participant who accepts
          --------------------------------                              
          severance benefits is obligated to reimburse the Company for the full
          amount of such payments if the Participant subsequently discloses any
          of the Company's trade secrets, violates any 

                                      -5-

 
          written covenants between the Participant and the Company, or
          otherwise engages in conduct that may adversely affect the Company's
          reputation or business relations. Likewise, a Participant who engages
          in such conduct shall forfeit any right to any unpaid severance
          payments.

     (f)  Effect of Adverse Economic Conditions.  The Company may permanently
          -------------------------------------                              
          suspend benefits under severance allowances in pay status (1) in the
          event of the Company's insolvency, liquidation, or bankruptcy
          reorganization or (2) in the event the cost of providing such benefits
          would lead to the Company's insolvency, liquidation, or bankruptcy
          reorganization.

     (g)  Effect of Other Severance Pay Laws.  Any severance benefits provided
          ----------------------------------                                  
          by the Company under this Plan shall be reduced dollar-for-dollar by
          any severance, separation, or any other termination pay benefit that
          the Company or any of its subsidiaries is required to pay to an
          eligible Participant under any federal or state law.

     (h)  Effect of Catastrophes and Other Extraordinary Events.  Severance
          -----------------------------------------------------            
          payments will not be made if the Participant's employment is
          terminated because of fire, flood, explosion, bombing, earthquake or
          other disaster causing damage to the location facilities or when
          strikes, work stoppages or civil disturbances prevent continued
          operations.

     (i)  Effect of Temporary Layoffs.  Severance payments will not be made if a
          ---------------------------                                           
          layoff is deemed to be temporary and of limited duration, e.g., a need
          for inventory reduction in a production facility or activities closely
          aligned with it.  During such periods, Participants are encouraged to
          take any available vacation to which they may be entitled.

     (j)  Non-Compete Agreement.  The Participant who has been involuntarily
          ---------------------                                             
          terminated may be required to execute a Non-Compete Agreement when the
          Committee determines that such an Agreement is required to protect the
          Company.  Any Participant who is asked to execute a Noncompete
          Agreement will receive severance in the amount of One Thousand Dollars
          ($1,000) as consideration for the Noncompete Agreement.  The Non-
          Compete Agreement must be signed and returned to the Company within 60
          days after the Participant's termination date in order for the
          Participant to receive benefits under this Plan.

     3.03 Condition Precedent to Severance Payments.  For the Employee who
          -----------------------------------------                       
becomes eligible for severance payments under Section 2.02 of the Plan because
the Company eliminates the Participant's position or because the Participant's
position has been fundamentally altered, severance payments will not be paid
under any circumstances until the eligible Participant 

                                      -6-

 
executes a Company approved release of the Participant's then existing rights
and claims against the Company. The release must be signed and returned to the
Company within 60 days after the Participant's Date of Termination in order for
the Participant to receive benefits under this Plan. For the Employee who
becomes eligible for benefits under the Plan for any other reason, the Committee
may but is not required to obtain the release mentioned above.

     3.04 Impact of Armstrong Employment Protection Plan.  Notwithstanding
          ----------------------------------------------                  
anything to the contrary in this Plan, in the event the Participant's Date of
Termination coincides with or follows a change in control, as defined in the
Armstrong Employment Protection Plan, no benefits will be paid under this Plan.
This Plan applies only in the case of an eligible Participant whose employment
has been terminated by the Company prior to the change in control and who is
otherwise eligible to receive a benefit hereunder.

4.   AMENDMENT OR TERMINATION.

     The Executive Committee of the Board of Directors of the Company may by
written resolution terminate or amend this Plan at any time, provided that no
amendment or termination of the Plan may adversely affect the amount, type, or
timing of payment of benefits accrued and due and payable hereunder with respect
to Participants whose employment has been terminated, except as provided in
Section 3.02 of this Plan.  Notwithstanding the foregoing, the Executive
Committee of the Board of Directors has delegated the authority to amend the
Plan to the Retirement Committee; provided, however, that the Executive
Committee reserves the right to rescind or modify such delegation at any time
and for any reason and retains the right to amend the Plan itself at any time.

5.   ADMINISTRATION

     5.01 Responsibility for administration of the Plan shall be vested in the
Committee, which shall have the sole and exclusive discretionary authority to
determine conclusively all questions arising in connection with the
administration, interpretation and application of the Plan, either by general
rules or by particular decisions, including (but not limited to) questions
regarding eligibility for benefits hereunder and the amount, form and timing of
payments thereof, and any other matter (including any question of fact) raised
by a claimant or identified by the Committee.  Any such determination by the
Committee shall be binding and conclusive upon all persons.  The Committee may
correct any defect, supply any information, or reconcile any inconsistency in
such manner and to such extent as shall be deemed necessary or advisable by it
to carry out the purpose of this Plan.  The Committee may delegate
administrative tasks as necessary to persons who are not Committee members.

     5.02 All expenses of administering the Plan shall be borne by the Company.
No member of the Committee shall receive any remuneration for service in such
capacity.  However, 

                                      -7-

 
expenses of the Committee or its members paid or incurred in connection with
administering the Plan shall be reimbursed by the Company.

     5.03 The Company may purchase insurance to cover potential liability of the
Plan's fiduciaries.  The Plan may purchase insurance for its fiduciaries and/or
for itself to cover liability and losses occurring by reason of the act or
omission of a fiduciary.

     5.04 The Plan is unfunded and all severance payments under the Plan shall
be made from the general assets of the Company.

6.   SUCCESSORS; BINDING AGREEMENT

     6.01 In the event of a sale or transfer of a plant, unit, division, or
subsidiary of the Company to a successor (whether by reason of a sale of stock
or assets) by means of which any Employee continues employment with the
successor organization or is offered employment with the successor organization,
the Company shall not be obliged to negotiate with the successor organization
over whether to establish any severance pay plan, policy, or practice with
respect to such Employees or whether to cover such Employees under any existing
severance pay plan, policy, or practice already maintained by the successor
organization.

     6.02 All rights of an eligible Employee hereunder shall inure to the
benefit of and be enforceable by such Employee's personal or legal
representatives, executors, administrators, successors, heirs, distributees,
devisees and legatees.  If an eligible Employee should die after having
satisfied all conditions precedent to the receipt of such benefits, but prior to
receiving all amounts of benefits payable hereunder, all such amounts, unless
otherwise provided herein, shall be paid in a lump sum in accordance with the
terms of this Plan to the Employee's devisee, legatee, or other designee or, if
there be no such designee, to the Employee's estate.

7.   ARBITRATION.

     Any dispute or controversy arising under or in connection with this Plan
shall be settled exclusively by arbitration in Lancaster County, Pennsylvania,
in accordance with the rules of the American Arbitration Association then in
effect.  Judgment may be entered on the arbitrator's award in any court having
jurisdiction.

8.   MISCELLANEOUS

     8.01 No amount payable under the Plan shall be subject to assignment,
transfer, sale, pledge, encumbrance, alienation or change by an eligible
Employee or the beneficiary of such Employee except as may be required by law.

                                      -8-

 
     8.02 Neither the Plan nor any action taken hereunder shall be construed
either (1) as giving any individual employed by the Company any right to receive
severance benefits of a type or in any amount similar to the benefits described
in Section 3.01 above, unless the individual qualifies for benefits under this
Plan; or (2) as giving any Employee any right to be retained in the employ of
the Company.

     8.03 Payments of benefits under this Plan shall be made in lieu of payments
of any severance benefits of a type similar to the benefits described in Section
3.01 above that may be offered under any written or unwritten severance pay
