1 Exhibit 10.23 July 16, 1999 Stephen J. Perkins President and Chief Operating Officer Commercial Intertech Corp. 1775 Logan Avenue Youngstown, OH 44501 Re: Change of Control Nonqualified Deferred Compensation Benefit Dear Steve: In your employment agreement, the Company agreed to provide you with a supplemental executive retirement plan (SERP). The primary purpose of the SERP is to make up the amount of your retirement benefit lost from the Pension Plan for Salaried Employees of Commercial Intertech Corp. (Pension Plan) due to federal laws that limit the amount of compensation taken into account under, and the amount of benefit payments provided by, qualified retirement plans. Certain Commercial Intertech SERPs also consider bonus in the formula that is excluded under the Pension Plan formula. Normal retirement benefits to you under the SERP will vest after the completion of five years of service with the Company, identical to the vesting provisions of the Pension Plan. Furthermore, the Company agreed to provide you some coverage in the event of a change of control prior to vesting in five years. This letter will clarify the latter concept. The Company will adopt a plan to provide the above benefit, named the Commercial Intertech Corp. Nonqualified Deferred Compensation Plan for Stephen J. Perkins, incorporating the non-change of control concepts set forth above. Furthermore, the Plan will include change of control benefit concepts as follows: - change of control benefit vests immediately upon change of control, as such phrase is defined in your Change of Control Agreement; - at your election, the change of control benefit may be received as a lump sum under actuarial principles (mortality tables and interest rates) as provided in other Company SERPs; 2 - service, for purposes of the calculation of the change of control benefit, will be the greater of (1) four years of service or (2) your actual years of service with the Company; and - compensation, for purposes of the calculation of the change of control benefit, will be the greater of (1) $500,000 per year or (2) your actual compensation as defined in the plan, base salary plus base target award plan bonus. A nonqualified deferred compensation plan document will be prepared and submitted to the Management Evaluation and Compensation Committee. If you have any questions concerning this please do not hesitate to call. Otherwise, acknowledge your understanding of these provisions by signing below. Very truly yours, Bruce C. Wheatley Senior Vice President - Administration Agreed: ____________________________ Stephen J. Perkins BCW:ljl 3 COMMERCIAL INTERTECH CORP. NONQUALIFIED DEFERRED COMPENSATION PLAN FOR STEPHEN J. PERKINS (Effective as of May 1, 1999) ARTICLE I ESTABLISHMENT AND CONSTRUCTION 1.1 ESTABLISHMENT. Commercial Intertech Corp.

The Company maintains the Pension Plan which is intended to meet the requirements of a "qualified" retirement plan under Section 401(a) of the Internal Revenue Code. The Pension Plan contains certain restrictions required by the Code that sometimes result in a diminution of benefits available to certain highly compensated employees. This Plan is established to replace some of the benefits lost due to this diminution and preclusion or upon a Change of Control. Also, this Plan is intended to be an unfunded deferred compensation plan for a member of a select group of management or highly compensated employees, as described in Sections 201(2), 301(a)(3), and 401(a)(1) of the Employee Retirement Income Security Act of 1974 ("ERISA"). 4 ARTICLE II DEFINITIONS AND CONSTRUCTION 2.1 DEFINITIONS.

Where the defined meaning is intended, the term is capitalized. 2.2 GENDER AND NUMBER. Except when otherwise indicated by the context, words in the masculine gender shall include the feminine and neuter genders; the plural shall include the singular and the singular shall include the plural. 2.3 EMPLOYMENT RIGHTS.

Each alternate form of payment shall be the Actuarial Equivalent of a single life annuity.

The lump sum shall be the present value of the annuity calculated under this Plan using the basis defined below that produces the largest lump sum amount: (1) the UP-1984 mortality table and the PBGC interest rate used for purposes of determining present value of a lump sum 9 distribution on plan termination as in effect on the date of the Participant's election, or (2) the UP-1984 mortality table and the PBGC interest rate used for purposes of determining present value of a lump sum distribution on plan termination as in effect on the date six (6) months prior to the date of the Participant's election, or (3) the 1983 GAM mortality table and the applicable interest rate promulgated by the Internal Revenue Service under Code Section 417(e)(3) for the month in which the Participant's election occurs, or (4) the 1983 GAM mortality table and the applicable interest rate promulgated by the Internal Revenue Service under Code Section 417(e)(3) for the month which is six (6) months prior to the Participant's election. The Participant may elect any combination of form of benefits not exceeding two (2). 3.5 EARLY DISTRIBUTION. Notwithstanding any other provision contained in this Plan, the Company shall make distributions to the Participant before such distributions otherwise are payable under this Plan if it determines upon the advice of counsel, based on a change in the Code, a published ruling or similar announcement issued by the Internal Revenue Service ("IRS"), a regulation issued by the Secretary of the Treasury or his delegate, a decision of a court of competent jurisdiction involving the Participant or a closing agreement involving the Participant that is approved by the IRS, that the Participant has recognized or will recognize income for federal income tax consequences with respect to amounts that are or will be distributable to him. 10 ARTICLE IV GENERAL PROVISIONS 4.1 ADMINISTRATION. This Plan shall be administered by the Compensation Committee of the Board of Directors. The Compensation Committee shall have, to the extent appropriate, the same powers, rights, duties and obligations with respect to this Plan as the plan administrator under the Pension Plan has under such Pension Plan. 4.2 FINALITY OF DETERMINATION. Except with respect to questions arising from benefits payable upon a Change of Control, the determination of the Compensation Committee as to any disputed questions arising under this Plan, including questions of construction and interpretation, shall be final, binding and conclusive upon all persons. 4.3 EXPENSES. The expenses of administering the Plan shall be borne by the Company. 4.4 INDEMNIFICATION AND EXCULPATION. The members of the Compensation Committee, its agents and officers, directors and employees of the Company and the Subsidiaries shall be indemnified and held harmless by the Company against and from any and all loss, cost, liability or expense that may be imposed upon or reasonably incurred by them in connection with or resulting from any claim, action, suit or proceeding to which they may be a party or in which they may be involved by reason of any action taken or failure to act under this Plan and against and from any and all amounts paid by them in settlement (with the Company's written approval) or paid by them in satisfaction of a judgment in any such action, suit or proceeding. The foregoing provision shall not be applicable to any person if the loss, cost, liability or expense is due to such person's gross negligence or willful misconduct. 4.5 FUNDING. While all benefits payable under the Plan constitute general corporate obligations, the Company shall establish a master rabbi trust for the benefit of the Participant, which trust shall be subject to the claims of the general creditors of the Company (and of any Subsidiary which has employed the Participant and become obligated under the Plan) in the event of such corporation's insolvency, to be used as a reserve for the discharge of the Company's or Subsidiary's obligations under the Plan to such Participant. The Company shall contribute to such trust an amount sufficient to fund the aggregate present value of all liabilities potentially owed to the Participant under this Plan and such funding shall occur no later than the date on which 11 a Change of Control occurs. Any payments made to the Participant under the trust for his benefit shall reduce dollar for dollar the amount payable to the Participant from the general assets of the Company or Subsidiary. The amounts payable under the Plan shall be reflected on the accounting records of the Company or Subsidiary but shall not be construed to create or require the creation of a trust, custodial or escrow account, except as described above in this section. The Participant (or Spouse of Participant) shall not have any right, title or interest whatever in or to any investment reserves, accounts or funds that the Company or any Subsidiary may purchase, establish or accumulate to aid in providing benefits under this Plan. Nothing contained in this Plan, and no action taken pursuant to its provisions, shall create a trust or fiduciary relationship of any kind between the Company or any Subsidiary and the Participant or any other person, except as described above in this section. Neither the Participant nor Spouse of the Participant shall acquire any interest greater than that of an unsecured creditor. 4.6 CORPORATE ACTION. Any action required of or permitted by the Company or any Subsidiary under this Plan shall be by resolution of its Board of Directors or any person or persons authorized by resolution of such Board of Directors. 4.7 INTERESTS NOT TRANSFERABLE. The interests of the Participant and his Spouse under the Plan are not subject to the claims of their creditors and may not be voluntarily or involuntarily transferred, assigned, alienated or encumbered. 4.8 EFFECT ON OTHER BENEFIT PLANS. Amounts credited or paid under this Plan shall not be considered to be compensation for the purposes of the Pension Plan maintained by the Company or any Subsidiary. The treatment of such amounts under other employee benefits plans shall be determined pursuant to the provisions of such plans. 4.9 TAX LIABILITY. The Company or Subsidiary may withhold from any payment of benefits hereunder any taxes required to be withheld and such sum as such employer may reasonably estimate to be necessary to cover any taxes for which the Company or Subsidiary may be liable and which may be assessed with regard to such payment. 4.10 LEGAL FEES AND EXPENSES. The Company shall pay all legal fees and expenses which the Participant may incur as a result of the Company's or any Subsidiary's contesting the validity, enforceability or the Participant's interpretation of, or determinations under, this Plan. 12 4.11 SUCCESSORS AND ASSIGNS. This Plan and all of the obligations hereunder shall be binding on the successors and assigns of the Company. 4.12 NONDUPLICATION OF BENEFITS. The benefits payable under this Plan to a Participant are intended to replace such benefits payable to such Participant under the Commercial Intertech Corp. Supplemental Executive Retirement Plan, and the Participant's benefits under such plan are terminated. 13 ARTICLE V AMENDMENT AND TERMINATION The Company by action of this Board of Directors reserves the right to amend this Plan from time to time or to terminate the Plan at any time, but without the written consent of the Participant, no such action may reduce or relieve the Company or any Subsidiary of any obligation with respect to any benefit accrued under the Plan by such Participant as of the date of such amendment or termination.
