                                   ARTICLE II

                         PURPOSE AND NATURE OF THE PLAN

2.1      Purpose

         The purpose of this Plan is to provide retirement income benefits in
         excess of those permitted from time to time under Code Section 401(a)
         for qualified retirement plans.

2.2      Nature

         The Plan is intended to be an unfunded, nonqualified plan maintained by
         the Company primarily for the purpose of providing deferred
         compensation for a select group of management or highly compensated
         employees within the meaning of Sections 201(2), 
   7
         301(a)(3), and 401(a)(1) of the Employee Retirement Income Security Act
         of 1974, as amended. In the event it is ultimately determined that a
         Participant is neither one of the select group of management employees
         or highly compensated employees, he shall cease to participate in the
         Plan.

2.3      No Trust Fund or Segregation of Assets Required

         Neither the Company, the Benefits Committee, nor its individual
         members, shall segregate or otherwise identify specific assets to be
         applied to the purposes of the Plan, nor shall any of them be deemed to
         be trustee of any amounts to be paid under the Plan. Any liability of
         the Company to any person with respect to benefits payable under the
         Plan shall be based solely upon such contractual obligations, if any,
         as shall be created by the Plan, and shall give rise only to a claim
         against the general assets of the Company, as the case may be. No such
         liability shall be deemed to be secured by any pledge or any other
         encumbrance on any specific property of the Company.
   8
                                   ARTICLE III

                          ELIGIBILITY AND PARTICIPATION

3.1      Eligibility

         Each Eligible Employee shall become a Participant when his Compensation
         exceeds the maximum amount of Compensation that may be taken into
         account under the Pension Plan under Code Section 401(a) and/or the
         amount of benefit he would have received under the Pension Plan is
         reduced because the Plan is redesigned to comply with the Tax Reform
         Act of 1986 and any regulations promulgated thereunder, including,
         without limitation, the regulations under the Code with respect to
         nondiscrimination under Code Section 401(a)(4) and coverage under Code
         Section 410(b).

3.2      Duration

         Each Participant shall remain a Participant until there are no longer
         any benefits payable in accordance with the benefit payment provisions
         of the Pension Plan.

3.3      Death Benefits

         The Participant's spouse, who would be entitled to a retirement, death
         or other benefit in accordance with the provisions of the Pension Plan
         upon the death of a Participant, shall be entitled to a benefit
         hereunder to the same extent that such benefit would otherwise have
         been payable in accordance with the provisions of the Pension Plan.
   9
                                   ARTICLE IV

                                PENSION BENEFITS

4.1      Amount of Benefit

         Upon a Participant's retirement, death, disability or other termination
         of employment, or upon termination of the Pension Plan on or after the
         Effective Date, a benefit shall be payable equal to (A) less (B),
         where:

                  (A) is the benefit (whether it be a retirement, death,
         disability, or termination of employment benefit or benefit upon
         Pension Plan termination), if any, determined under the applicable
         provisions of the Pension Plan, as in effect at the time of the
         Participant's retirement, death, disability or termination of
         employment, or termination of the Pension Plan, without regard to any
         limitation on such benefit imposed under said Pension Plan on account
         of the limitations of Code Sections 401(a) or 415, as modified from
         time to time, or any successor provisions thereto; and

                  (B) is the sum of (a) plus (b) where (a) is the benefit
         determined under the applicable provisions of the Pension Plan,
         (including any benefit from the Stanadayne, Inc. Salaried Pension Plan
         whether or not such benefit is payable under the Lincoln National Group
         Annuity Contract Number (GA-5844)), as limited by Code Sections 401(a)
         and 415, as modified from time to time, or any successor provision
         thereto; and (b) is the benefit determined under the applicable
         provisions of the BEP. The difference in benefits under Paragraphs (A)
         and (B), above, shall be the benefit payable under the terms of this
         Plan.

4.2      Form and Commencement of Benefit


                                       -5-
   10
         Any benefit payable under the terms of this Plan, shall be paid at the
         same time, in the same form, pursuant to the same vesting schedule and
         (except as otherwise provided in Section 4.4), over the same period of
         time, as the benefit payable under the Pension Plan.

4.3      Beneficiary

         Any benefit payable subsequent to the death of a Participant hereunder
         shall be paid to the Participant's spouse.

4.4      Optional Forms

         Each available optional form of benefit payment, shall be computed on
         an actuarial equivalent basis, applying the actuarial assumptions
         utilized by the Pension Plan.

4.5      Non-Alienation

         No Participant or spouse of a Participant, shall have any right to
         commute, encumber, transfer or otherwise dispose of or alienate any
         present or future right or expectancy which he may have at any time to
         receive payments of benefits hereunder, which benefits and the right
         thereto are expressly declared to be non-assignable and
         non-transferable, except to the extent required by law. Any attempt to
         transfer or assign a benefit, or any rights granted hereunder, by a
         Participant or his spouse shall, in the sole discretion of the Benefits
         Committee (after consideration of such facts as it deems pertinent), be
         grounds for terminating any rights of the Participant, or his spouse,
         to any portion of the Plan benefits not previously paid.

4.6      Claims Procedure


                                      -6-
   11
         A claim for the benefits hereunder may be made in writing to the
         Benefits Committee; provided, however, that a claim by a Participant
         for retirement benefits under the Pension Plan, shall be deemed to be a
         claim hereunder.

                                    ARTICLE V

                               BENEFITS COMMITTEE

5.1      Fiduciary Status

         Neither the Benefits Committee nor its individual members shall be
         deemed to be a fiduciary with respect to the Plan.

5.2      Quorum

         A majority of the members of the Benefits Committee shall constitute a
         quorum for any meeting held with respect to the Plan, and the acts of a
         majority of the members present at any meeting at which a quorum is
         present, or the acts unanimously approved in writing by all such
         members, shall be valid acts.

5.3      Powers of Benefits Committee

         The Benefits Committee shall have the power and duty to do all things
         necessary or convenient to effect the intent and purposes of the Plan
         and not inconsistent with any of the provisions hereof, whether or not
         such powers and duties are specifically set forth herein, and, by way
         of amplification and not limitation of the foregoing, the Benefits
         Committee shall have the power to:


                                      -7-
   12
                  (A) provide rules and regulations for the management,
                  operation and administration of the Plan, and, from time to
                  time, to amend or supplement such rules and regulations;

                  (B) construe the Plan, which construction, as long as made in
                  good faith, shall be final and conclusive upon all parties
                  hereto; and

                  (C) correct any defect, supply any omission, or reconcile any
                  inconsistency in the Plan in such manner and to such extent as
                  it shall deem expedient to carry the same into effect, and it
                  shall be the sole and final judge of when such action shall be
                  appropriate.

5.4      Conclusive Effect of Determination

         The acts and determinations of the Benefits Committee within the powers
         conferred by the Plan shall be final and conclusive for all purposes of
         the Plan, and shall not be subject to appeal or review by persons or
         entities other than the Board of Directors.


                                      -8-
   13
5.5      Liability; Indemnification

         No member of the Benefits Committee shall be directly or indirectly
         responsible or under any liability by reason of any action or default
         by him as a member of the Benefits Committee, or the exercise of or
         failure to exercise any power or discretion as such member; except for
         his own fraud or willful misconduct. No member of the Benefits
         Committee shall be liable in any way for the acts or defaults of any
         other member of the Benefits Committee, or any of its advisors, agents
         or representatives. The Company shall indemnify and save harmless each
         member of the Benefits Committee against any and all expense and
         liabilities arising out of his own membership on the Benefits
         Committee; except expenses and liabilities arising out of a Benefits
         Committee member's own fraud or willful misconduct.

5.6      Compensation

         Members of the Benefits Committee who are employees of the Company
         shall receive no compensation for their services rendered as members of
         the Benefits Committee. Any other members of the Benefits Committee may
         receive such reasonable compensation for their services as may be
         authorized from time to time by the Board of Directors and, except as
         otherwise provided by this Article, shall be entitled to receive their
         reasonable expenses incurred in administering the Plan. Any such
         compensation and expenses, as well as extraordinary expenses authorized
         by the Board of Directors, shall be paid by the Company.

5.7      Company to Provide Information


                                      -9-
   14
         The Company shall furnish to the Benefits Committee in writing all
         information the Company deems appropriate for the Benefits Committee to
         exercise its powers and duties in the administration of the Plan.

         Such information may include, but shall not be limited to, the names of
         all Participants, their earnings and their dates of birth, employment,
         termination of employment, retirement or death. Such information shall
         be conclusive for all purposes of the Plan and the Benefits Committee
         shall be entitled to rely thereon without any investigation thereof;
         provided, however, that the Benefits Committee may correct any errors
         discovered in any such information.

5.8      Availability of Reports

         The Benefits Committee shall make available, at the request of each
         Participant and spouse, for examination at the principal office of the
         Company (or at such other location as may be determined by the Benefits
         Committee), a copy of the Plan and such of its records, or copies
         thereof, as may pertain to any benefits of such Participant or spouse
         under the Plan.

5.9      Conflicts of Interest

         No member of the Benefits Committee may act, vote, or otherwise
         influence a decision of the Benefits Committee specifically relating to
         his benefits, if any, under the Plan.


                                   ARTICLE VI

                               GENERAL PROVISIONS

6.1      Benefits Payable by Company


                                      -10-
   15
         Any Participant who may have or claim any interest in or right to any
         compensation, payment, or benefit payable hereunder, shall rely solely
         upon the unsecured promise of the Company as set forth herein for the
         payment thereof, and nothing herein contained shall be construed to
         give to or vest in the Participant or any other person now or at any
         time in the future, any right, title, interest, or claim in or to any
         specific asset, fund, reserve, account, insurance or annuity policy or
         contract, or other property of any kind whatever owned by the Company,
         or in which the Company may have any right, title, or interest, now or
         at any time in the future.

6.2      Effect on Other Plans

         It is agreed and understood that any benefits accrued under this Plan
         are in addition to any and all employee benefits to which a Participant
         may otherwise be entitled under any other contract, arrangement, or
         voluntary pension, profit sharing or other compensation plan of the
         Company, whether funded or unfunded, and that this Plan shall not
         affect or impair the rights or obligations of the Company or a
         Participant under any other such contract, arrangement, or voluntary
         pension, profit sharing or other compensation plan.


                                      -11-
   16
6.3      Amendment or Termination

         This Plan may be amended, modified, suspended, or terminated by the
         Board of Directors if and when it deems such action necessary,
         provided, however, that notwithstanding the foregoing, no such
         amendment, modification, suspension or termination shall reduce the
         benefit to which a Participant or spouse was entitled immediately prior
         to such amendment, modification, suspension, or termination. No
         Participant or spouse shall have any contractual right to future
         benefits otherwise payable, as of the date of such action by the Board
         of Directors.

6.4      Severability

         If any term or condition of the Plan shall be invalid or unenforceable
         to any extent or in any application, then the remainder of the Plan,
         with the exception of such invalid or unenforceable provision, shall
         not be affected thereby, and shall continue in effect and application
         to its fullest extent.

6.5      Status of Employment

         Neither the establishment of the Plan, any provisions of the Plan, nor
         any action of the Benefits Committee shall be held or construed to
         confer upon any employee the right to a continuation of employment by
         the Company. Subject to any applicable employment contract, the Company
         reserves the right to dismiss any employee, or otherwise deal with any
         employee to the same extent as though the Plan had not been adopted.

6.6      Payments to Incompetents

         If the Benefits Committee determines that a Participant or spouse is
         unable to care for his affairs because of illness or accident, or is a
