(a)-(c); (f) This Statement is being jointly filed by PEM Holding Co., a Delaware corporation (“PEM”), and Tinicum Investors, a Delaware general partnership (“Investors” and, together with PEM, the “Reporting Persons”). PEM is a holding company formed for the purpose of effecting the Merger (as defined below), with its principal business address and principal office at c/o Tinicum Lantern II L.L.C., 800 Third Avenue, 40^th Floor, New York, NY 10022. PEM is currently a wholly owned subsidiary of Tinicum Capital Partners II, L.P., a Delaware limited partnership (“TCP”), although additional investors, including certain affiliates of TCP, may acquire shares of PEM at or prior to the closing of the Merger. Investors is a private investment partnership with its principal business address and principal office at 990 Stewart Avenue, Garden City, New York 11530. For information required by General Instruction C to Schedule 13D, reference is made to Exhibit A attached hereto which is incorporated herein by reference to this Item 2.

(d)-(e) Neither of the Reporting Persons, nor, to the knowledge of the Reporting Persons, any person listed on Exhibit A hereto, has during the last five years (i) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) been a party to any civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which such person was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

As an inducement for PEM to enter into the Agreement and Plan of Merger (the “Merger Agreement”), dated as of January 17, 2005, by and among PEM, PN Merger Sub, Inc., a wholly owned subsidiary of PEM, and the Company, and in consideration thereof, PEM entered into an Option and Voting Agreement (the “Voting Agreement”), dated as of January 17, 2005, with Kenneth A. Swanstrom, the Chairman, Chief Executive Officer and a director of the Company, Daryl L. Swanstrom, a director of the Company, and Frederick Dreher as trustees of certain trusts listed in Item 5(b) below and, in the case of Kenneth A. Swanstrom and Daryl L. Swanstrom, individually (collectively, the “Stockholders”), with respect to certain shares beneficially owned by the Stockholders. PEM did not pay and does not expect to pay additional consideration to the Stockholders in connection with the execution and delivery of the Voting Agreement. For a description of the Merger Agreement and Voting Agreement see Item 4 below, which descriptions, together with copies of the Merger Agreement and Voting Agreement attached as Exhibits B and C hereto, respectively, are incorporated by reference herein. Investors used funds of the partnership to purchase the 2,000 shares of Class A Common Stock owned by it.

This Item 3 is not applicable to the persons listed on Exhibit A hereto.

4

The purpose of PEM entering into the Voting Agreement with the Stockholders is to facilitate the transactions contemplated by the Merger Agreement, as described below.

Investors acquired its 2,000 shares of Class A Common Stock for investment purposes.

The following is a description of the relationship among PEM and the Stockholders under the Merger Agreement and Voting Agreement but is not an affirmation by PEM of the existence of a group for purposes of Section 13 of the Securities Exchange Act of 1934, as amended.

The Merger Agreement

The Merger Agreement provides for the merger of Merger Sub, a wholly owned subsidiary of PEM, with and into the Company (the “Merger”). As a result of the Merger, the separate corporate existence of Merger Sub will cease, and the Company will continue as the surviving corporation in the Merger.

At the effective time of the Merger, each share of the Class A Common Stock and Common Stock, par value $.01 per share (the “Common Stock” and, together with the Class A Common Stock, the “Company Common Stock”), other than shares of Company Common Stock as to which dissenters’ appraisal rights are perfected under Delaware law and shares of Company Common Stock held by the Company or any of its subsidiaries or by PEM or any of its subsidiaries, will be canceled and be automatically converted into and thereafter only represent the right to receive cash, without any interest, in the amount of $18.25 (the “Merger Consideration”). Options to purchase Common Stock that are outstanding and unexercised at the effective time of the Merger will be canceled and be converted automatically into the right to receive from the surviving corporation a cash payment for each share of Common Stock subject to the stock option in an amount equal to the Merger Consideration less the per share exercise price of the stock option and all applicable federal and state tax withholding obligations of the optionee.

The Merger is subject to approval by the holders of a majority of the Company’s outstanding Class A Common Stock. In addition, the Merger is subject to the notification and waiting-period requirements under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, as well as other customary closing conditions. PEM’s obligation to consummate the Merger is also subject to receipt of proceeds from its lenders under financing commitments that have been obtained by an affiliate of PEM.

The Company and PEM have made customary representations, warranties and covenants in the Merger Agreement, including the Company’s making covenants not to solicit alternative transactions or, subject to certain exceptions, to enter into discussions concerning, or provide confidential information in connection with, an alternative transaction.

The Merger Agreement contains certain termination rights for both the Company and PEM, and further provides that, upon termination of the Merger Agreement under certain circumstances, the Company may be obligated to pay PEM a termination fee of $10.0 million plus certain expenses not exceeding $5.0 million.

5

The Voting Agreement

The Voting Agreement provides that, during the period from the execution of the Voting Agreement to the earlier of the date on which the Merger Agreement is terminated in accordance with its terms or the effective date of the merger (the “Proxy Term”), each Stockholder agrees that, at any annual, special or other meeting of stockholders of the Company, the Stockholder will:

The Voting Agreement also provides that neither PEM nor any of its affiliates will purchase or otherwise acquire during the Proxy Term any interest, including any voting or dispositive rights, in any additional shares of Class A Common Stock or take any other action that would result in the automatic conversion of the Common Stock into shares of Class A Common Stock. The Voting Agreement also restricts the ability of the Stockholders to transfer or dispose of or agree to transfer or dispose of shares of Company Common Stock.

The Stockholders have also granted to PEM an irrevocable option to purchase from the Stockholders certain shares of Company Common Stock at a purchase price per share equal to $18.25 if PEM and the Company agree to make adjustments to the terms and conditions of the Merger Agreement so that a third party acquisition proposal no longer constitutes a Superior Proposal, as such term is defined in the Merger Agreement.

In addition, if within 12 months following the termination of the Merger Agreement for reasons that would trigger the payment of a termination fee or expense payment by the Company the Stockholders sell shares to a third party in connection with a transaction whereby the third party acquires more than 50% of the voting power of the Class A Common Stock or a majority of the equity interest in the Company, then the Stockholders must pay to PEM 25% of the amount, if any, by which the consideration received in such transaction exceeds $18.25, for certain shares of Company Common Stock subject to the Voting Agreement.

The foregoing descriptions of the transactions contemplated by the Merger Agreement and the Voting Agreement are qualified in their entirety by reference to the respective agreements, copies of which are attached hereto as Exhibits B and C respectively. Exhibits B and C are specifically incorporated herein by reference to this Item 4.

MERGER CONSIDERATION; EXCHANGE PROCEDURES

3.1 Conversion of Shares.

(a) Subject to the provisions of this Agreement, each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than Dissenting Shares and Treasury Shares), shall, by virtue of the Merger, be cancelled and shall as of the Effective Time automatically be converted into and shall thereafter only represent the right to receive cash, without any interest, in the amount of $18.25 (the “Merger Consideration”).

(b) At and after the Effective Time, all Treasury Shares shall be cancelled and retired and no Merger Consideration shall be delivered in exchange therefor.

(c) At the Effective Time, the stock transfer books of the Company shall be closed as to holders of Company Common Stock immediately prior to the Effective Time and no transfer of Company Common Stock by any such holder shall thereafter be made or recognized. If, after the Effective Time, Certificates are properly presented in accordance with Section 3.2 of this Agreement to the Paying Agent, such Certificates shall be cancelled and exchanged for a check representing the Merger Consideration into which Company Common Stock represented thereby was converted in the Merger.

(d) At and after the Effective Time, each share of capital stock of Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one validly issued, fully paid and nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation and the shares so converted shall constitute the only outstanding shares of capital stock of the Surviving Corporation.

3.2 Exchange Procedures.

(a) Promptly following the Effective Time of the Merger, Purchaser shall deposit or cause to be deposited with the Paying Agent for the benefit of the holders of shares of Company Common Stock, for exchange in accordance with this Section 3.2, cash in that amount as is equal to the aggregate Merger Consideration required to be paid pursuant to Section 3.1 in exchange for the shares of Company Common Stock outstanding immediately prior to the Effective Time of the Merger (the “Exchange Fund”). The Transfer Agent shall invest the Exchange Fund as directed by Purchaser on

B-10

a daily basis. Purchaser shall be obligated to promptly deposit funds in the Exchange Fund to make up any difference if at any time the amount in the Exchange Fund is less than the aggregate Merger Consideration less amounts paid by the Paying Agent to holders of shares of Company Common Stock. The Exchange Fund shall not be used for any other purpose, it being understood that any and all interest earned on and other income resulting from investment of the Exchange Fund shall be promptly paid to Purchaser.

(b) Within ten Business Days after the Effective Time, Purchaser shall cause the Paying Agent to mail to each holder of record of a Certificate, other than holders of Certificates representing Dissenting Shares and Treasury Shares, (i) a form of letter of transmittal, which shall specify that delivery shall be effected and risk of loss and title to the Certificates shall pass only upon proper delivery of the Certificates to the Paying Agent and which shall be in customary form and have such other provisions as Purchaser and the Company may reasonably agree and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration. Each holder of record who surrenders such Certificate or, in accordance with Section 3.7, an affidavit and, if required, a bond regarding the loss or destruction of such Certificate, together with duly executed letter of transmittal materials, to the Paying Agent shall, upon acceptance thereof, be entitled to the cash into which the shares of Company Common Stock represented by the Certificate shall have been converted pursuant to Section 3.1. The Paying Agent shall accept such Certificate upon compliance with such reasonable and customary terms and conditions as the Paying Agent may impose to effect an orderly exchange thereof in accordance with normal practices. Until surrendered as contemplated by this Section 3.2, each Certificate representing Company Common Stock shall be cancelled and, other than Certificates representing Dissenting Shares and Treasury Shares, be deemed from and after the Effective Time of the Merger to evidence only the right to receive the Merger Consideration to which the holder of such Certificate is entitled hereunder upon such surrender. Purchaser shall not be obligated to deliver the Merger Consideration to which any former holder of Company Common Stock is entitled as a result of the Merger until such holder surrenders such holder’s Certificate or Certificates for exchange as provided in this Section 3.2. If any check representing cash is to be issued in a name other than that in which a Certificate surrendered for exchange is issued, the Certificate so surrendered shall be properly endorsed and otherwise in proper form for transfer and the Person requesting such exchange shall affix any requisite stock transfer tax stamps to the Certificate surrendered or provide funds for their purchase or establish to the satisfaction of the Paying Agent that such taxes have been paid or are not payable.

(c) All cash paid upon the surrender for exchange of shares of Company Common Stock in accordance with the terms hereof shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of Company Common Stock.

3.3 Dissenting Shares. Notwithstanding anything to the contrary contained in this Agreement, any holder of Company Common Stock who shall be entitled to be paid the “fair value” of such holder’s Dissenting Shares, as provided in Section 262 of the

B-11

DGCL, shall not be entitled to the consideration to which such holder would otherwise have been entitled pursuant to Sections 2.1 and 3.1, unless and until such holder shall have failed to perfect or withdrawn or lost such holder’s rights under Section 262 of the DGCL, and shall be entitled to receive only such payment as is provided for by Section 262 of the DGCL. At the Effective Time, all Dissenting Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each holder of Dissenting Shares shall cease to have any rights with respect thereto, except the right to receive the fair value of such shares in accordance with the provisions of Section 262 of the DGCL. If, after the Effective Time, such dissenting stockholder withdraws such stockholder’s demand for appraisal or fails to perfect or otherwise loses such stockholder’s right of appraisal, in any case pursuant to the DGCL, such stockholder’s shares of Company Common Stock shall be deemed to be converted as of the Effective Time into the right to receive the Merger Consideration, without interest. The Company shall give Purchaser (i) prompt notice of any written demands for appraisal of shares of Company Common Stock received by the Company and (ii) the opportunity to participate in and direct all negotiations and proceedings with respect to any such demands. Prior to the Effective Date, the Company shall not, without the prior written consent of Purchaser, make any payment with respect to, or settle, offer to settle or otherwise negotiate, any such demands, or agree to do any of the foregoing.

3.4 Withholding Rights. Purchaser, through the Paying Agent, shall be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock such amounts as Purchaser is required under the Code or any Tax Law to deduct and withhold with respect to the making of such payment. Any amounts so withheld shall be treated for all purposes of this Agreement as having been paid to the holder of Company Common Stock in respect of which such deduction and withholding was made by Purchaser.

3.5 Company Options. At the Effective Time, each Company Option that is then outstanding and unexercised shall be cancelled and extinguished and cease to represent a right to acquire shares of Company Common Stock and shall be converted automatically into the right to receive from the Surviving Corporation a cash payment for each share of Company Common Stock subject to the Company Option in an amount equal to the Merger Consideration less the per share exercise price of the Company Option and less all applicable federal and state Tax withholding obligations of the optionee. The Company agrees that the Penn Engineering & Manufacturing Corp. 1996 Employees Stock Purchase Plan (the “ESPP”) shall be terminated prior to the Effective Time as provided in Section 4.1(b) of the Company Disclosure Schedule. Prior to the Effective Time, the Company shall take all actions necessary to terminate all of the Company Stock Option Plans and the ESPP, to cancel the Company Options and to otherwise implement the provisions of this Section 3.5.

3.6 Termination of Exchange Fund.

(a) Any portion of the Exchange Fund, including any interest earned thereon and other income resulting therefrom, that remains undistributed to the stockholders of the Company following the passage of six months after the Effective

B-12

Date shall be delivered by the Paying Agent to Purchaser, upon demand. Any stockholders of the Company who have not theretofore complied with Section 3.2 shall thereafter look only to Purchaser, and, subject to applicable Law, Purchaser shall be liable for, payment of the Merger Consideration.

(b) Neither the Company nor Purchaser shall be liable to any holder of shares of Company Common Stock for cash from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificate shall not have been surrendered prior to five years after the Effective Time (or immediately prior to such earlier date on which any cash in respect of such Certificate would otherwise escheat to or become the property of any Governmental Authority), any such cash in respect of such Certificate shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation, free and clear of all claims or interest of any Person previously entitled thereto.

3.7 Lost Certificates. If any Certificate shall have been lost, stolen, or destroyed, upon the making of an affidavit of that fact by the Person claiming the Certificate to be lost, stolen, or destroyed and, if required by Purchaser or the Surviving Corporation, the posting by that Person of a bond, in such reasonable amount as Purchaser or the Surviving Corporation may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent shall issue in exchange for such lost, stolen, or destroyed Certificate the Merger Consideration to be paid in respect of the shares represented by such Certificate as contemplated by this Article III.

(c) Any Indemnified Party wishing to claim indemnification under this Section 6.7, upon learning of any such claim, action, suit, proceeding or investigation, shall promptly notify the Indemnifying Party, but the failure to so notify shall not relieve the Indemnifying Party of any liability it may have to such Indemnified Party if such failure does not actually prejudice the Indemnifying Party. In the event of any such claim, action, suit, proceeding or investigation, whether arising before or after the Effective Time, (i) the Indemnifying Party shall have the right to assume the defense thereof and the Indemnifying Party shall not be liable to such Indemnified Parties for any legal expenses of other counsel or any other expenses subsequently incurred by such Indemnified Parties in connection with the defense thereof, except that if the Indemnifying Party elects not to assume such defense or counsel for the Indemnified Parties delivers an opinion that under applicable standards of professional conduct, there are significant issues between the positions of such Indemnified Party and any other Indemnified Party or Indemnified Parties that raise conflicts of interest between the Indemnifying Party and the Indemnified Parties, the Indemnified Parties may retain counsel that is reasonably satisfactory to the Indemnifying Party, and the Indemnifying Party shall pay, promptly as statements therefor are received, the reasonable fees and expenses of such counsel for the Indemnified Parties, which may not exceed one firm in any jurisdiction, (ii) the Indemnified Parties will cooperate in the defense of any such matter, (iii) the Indemnifying Party shall not be liable for any settlement effected without its prior written consent, which shall not be unreasonably withheld, (iv) the Indemnifying Party shall have no obligation hereunder in the event that a federal or state banking agency or a court of competent jurisdiction shall determine that indemnification of an Indemnified Party in the manner contemplated hereby is prohibited by applicable Laws and (v) the Indemnified Parties shall provide the Indemnifying Party with any undertaking that may be required by the Indemnified Party’s certificate of incorporation or bylaws or by the DGCL.

ARTICLE II

VOTING
