have been audited by PricewaterhouseCoopers LLP, independent accountants, as stated in their report appearing therein. Item 4. Description of Securities. Not Applicable Item 5. Interests of Named Experts and Counsel. Not Applicable Item 6. Indemnification of Directors and Officers. Subchapter D of Chapter 17 of the Pennsylvania Business Corporation Law of 1988, as amended (the "PBCL"), contains provisions relating to the indemnification of persons by a Pennsylvania business corporation, including directors and officers of the corporation. Sections 1741 and 1742 of the PBCL provide that a business corporation may indemnify directors and officers against liabilities and expenses they may incur as such provided that the particular person acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. In general, the power to indemnify under these sections does not exist in the case of actions against a director or officer by or in the right of the corporation if the person otherwise entitled to indemnification shall have been adjudged to be liable to the corporation unless it is judicially determined that, despite the adjudication of liability but in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnification for specified expenses. Section 1743 of the PBCL provides that the corporation is required to indemnify directors and officers against expenses they may incur in defending actions against them in such capacities if they are successful on the merits or otherwise in the defense of such actions. Section 1746 of the PBCL grants a corporation broad authority to indemnify its directors and officers for liabilities and expenses incurred in such capacity, except in circumstances where the act or failure to act giving rise to the claim for indemnification is determined by a court to have constituted willful misconduct or recklessness. Section 1747 of the PBCL permits a corporation to purchase and maintain insurance on behalf of any person who is or was a director or officer of the corporation, or is or was serving at the request of the corporation as a representative of another corporation or other enterprise, against any liability asserted against such person and incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not the corporation would have the power to indemnify the person against such liability under Subchapter D of Chapter 17 of the PBCL. The Registrant currently maintains directors and officers liability insurance on behalf of its directors and officers. 3

Section 7.1 of the Registrant's Bylaws contains provisions requiring the Registrant to indemnify and hold harmless directors and officers to the fullest extent and manner authorized or permitted by the laws of the Commonwealth of Pennsylvania. Item 7. Exemption from Registration Claimed. Not Applicable Item 8. Exhibits. Exhibit No. Description of Exhibits - ----------- ----------------------- 4. Quaker Chemical Corporation 2003 Director Stock Ownership Plan 5. Opinion of Wolf, Block, Schorr and Solis-Cohen LLP 23.1 Consent of Wolf, Block, Schorr and Solis-Cohen LLP (included as part of Exhibit 5 hereto) 23.2 Consent of PricewaterhouseCoopers LLP 24. Power of Attorney (included as part of the signature page hereto) Item 9. Undertakings. The undersigned registrant hereby undertakes: 1. To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (a)(l)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. 4

2. That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. 3. To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. 5

The interpretation and construction of any provision of the Plan by the Committee shall be final and conclusive. 4. Effective Date and Duration. The Plan shall not become effective unless it is approved by the Company's shareholders at the Company's 2003 annual meeting of its shareholders or at an adjournment of such meeting (the "Meeting"). For purposes of the Plan, approval of the Plan requires that the number of votes cast "FOR" approval exceed the number of votes cast "AGAINST" approval. If the Plan is approved at the Meeting, it shall become effective on the date it is so approved and shall remain in effect for a term of ten years or until it is earlier terminated by the Board. 5.

The shares of Common Stock issued under the Plan may be either authorized and unissued shares of Common Stock and/or authorized and issued shares of Common Stock purchased or acquired by the Company for any purpose. 6. Payment of Annual Retainer. (a) The Company will pay the Annual Retainer on the Retainer Payment Date. (b) Subject to adjustment in accordance with Section 6(g), if on the Measuring Date immediately preceding the 2003 Retainer Payment Date an Eligible Director is the Beneficial Owner of less than 5,000 shares of Common Stock, 75% of the Annual Retainer payable to the Eligible Director shall be paid in shares of Common Stock and 25% of the Annual Retainer shall be paid in cash. (c) Subject to adjustment in accordance with Section 6(g), if on the Measuring Date immediately preceding the 2003 Retainer Payment Date an Eligible Director is the Beneficial Owner of 5,000 or more shares of Common Stock, 35% of the Annual Retainer payable to the Eligible Director shall be paid in shares of Common Stock and 65% of the Annual Retainer shall be paid in cash. Notwithstanding the preceding sentence, if an Eligible Director made a Discretionary Election with respect to 2003, the Annual Retainer payable to the Eligible Director for 2003 shall be paid in accordance with the terms of the Discretionary Election. (d) Subject to adjustment in accordance with Section 6(g), if on the Measuring Date immediately preceding the Retainer Payment Date for 2004 or any subsequent year an Eligible Director is the Beneficial Owner of less than 7,500 shares of Common Stock, 75% of the Annual Retainer payable to the Eligible Director for such year shall be paid in shares of Common Stock and 25% of the Annual Retainer for such year shall be paid in cash.

(f) Shares of Common Stock issued in payment of the Annual Retainer shall be valued at Fair Market Value. (g) No fractional shares of Common Stock shall be issued pursuant to the Plan. The number of shares of Common Stock otherwise issuable to an Eligible Director on any Retainer Payment Date, if not a whole number, shall be rounded down to the nearest whole share, and any fractional share otherwise issuable shall be paid in cash. (h) The Plan is not intended, and shall not be deemed, to limit the authority of the Board or any committee of the Board that is so authorized by the Board to increase or decrease the amount of the Annual Retainer from time to time. 7. Discretionary Election. If on the Measuring Date immediately preceding the 2003 Retainer Payment Date an Eligible Director is the Beneficial Owner of 5,000 or more shares of Common Stock, or if on the Measuring Date immediately preceding a Retainer Payment Date in 2004 or a subsequent year an Eligible Director is the Beneficial Owner of 7,500 or more shares of Common Stock, the Eligible Director may, in the Eligible Director's discretion, within the 10-day period following the Measuring Date for the applicable year (the "Option Period"), irrevocably elect to receive Common Stock in payment of a percentage of the Annual Retainer for the applicable year which exceeds (but is not less than) 35%. A Discretionary Election, which shall be made on a form provided to the Eligible Director by the Company for that purpose and be received by the Committee prior to the expiration of the Option Period, shall state the percentage of the Annual Retainer to be paid in Common Stock, (which may be as much as 100%), and shall be dated and signed by the Eligible Director submitting the same. Any Discretionary Election that is made in accordance with this Section 7 shall be binding only with respect to the Annual Retainer payable in the year in which the Discretionary Election is made, and such Discretionary Election shall not be applicable to the Annual Retainer payable in any subsequent year. 8. Suspension, Termination and Amendment of the Plan. The Plan may be suspended, terminated or reinstated, in whole or in part, at any time by the Board. The Board may from time to time make such amendments to the Plan as it may deem advisable, provided, however, that (i) no such amendment shall be effected between a Measuring Date and the next succeeding Retainer Payment Date, and (ii) without the approval of the Company's shareholders, the Plan may not be amended to (A) increase the total number of shares of Common Stock which may be issued under the Plan (other than by adjustment of one or more of the respective numbers of shares referred to in Section 5, Subsections 6(b), 6(c), 6(d) and 6(e) and Section 7 in accordance with Section 9), (B) change the types of awards available under the Plan, (C) expand the class of persons eligible to acquire shares pursuant to the Plan, (D) extend the term of the Plan, (E) materially change the method of determining the price as to which shares are issued pursuant to the Plan, or (F) otherwise amend the Plan in a manner that requires approval of the Company's shareholders under the applicable requirements of any national stock exchange on which the Company's Common Stock is then listed. 9. Adjustment Provisions. In the event of any recapitalization, reorganization, merger, consolidation, spin-off, combination, share exchange, stock split or reverse split, liquidation, dissolution, or other similar corporate transaction or event which affects the Common Stock such that the Committee determines that an adjustment is appropriate in order to prevent dilution or enlargement of Eligible Directors' rights under the Plan, the Committee may make an adjustment in the number of shares of Common Stock subject to the Plan, and the respective numbers of shares of Common Stock referred to in Subsections 6(b), 6(c), 6(d) and 6(e) and Section 7. 3

10. Transfer Restriction. The shares of Common Stock acquired by an Eligible Director pursuant to the Plan shall not be sold or otherwise disposed of during the six-month period commencing with the Retainer Payment Date applicable to the shares. 11. General Provisions. (a) Notwithstanding any other provision of the Plan, the Company shall not be required to issue or deliver any certificate for shares of Common Stock prior to the fulfillment of all of the following conditions: (i) Any required listing or approval upon notice of issuance of such shares of Common Stock on any securities exchange on which the Common Stock may then be traded. (ii) Any registration or qualification of the shares of Common Stock subject to the Plan under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, if such registration shall be necessary. (iii) Any registration or qualification of the shares of Common Stock under any state or Federal law or regulation or other qualification which the Board deems necessary. (iv) Any other required consent or approval or permit from any state or Federal government agency. The Company shall use its best efforts to effect promptly such registrations, listings, qualifications or other approvals and to comply promptly with such laws, regulations and rulings. (b) Nothing contained in the Plan will confer upon any Director any right to continue to serve as a member of the Board. The Plan shall not interfere with or limit in any way the right of the Company to remove an Eligible Director from the Board. (c) The adoption of the Plan by the Board and approval of the Plan by the Company's shareholders shall not be construed as creating any limitations on the power of the Board to adopt such other compensatory arrangements for members of the Board as it may deem desirable. (d) To the extent not preempted by Federal law, the Plan shall be construed in accordance with and governed by the internal laws of the Commonwealth of Pennsylvania. (e) In the event any provision of the Plan or any action taken pursuant to the Plan shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of the Plan, and the Plan shall be construed and enforced as if the illegal or invalid provision had not been included, and the illegal or invalid action shall be deemed null and void. (f) The issuance of shares of Common Stock under the Plan shall be subject to applicable taxes or other laws or regulations of the United States of America or any state having jurisdiction. To the extent required by applicable law or regulation, an Eligible Director must arrange with the Company for the payment of any Federal, state or local income or other tax applicable to the receipt of Common Stock under the Plan before the Company shall be required to deliver to the Eligible Director a certificate for Common Stock. (g) Titles and headings of sections of the Plan are for convenience of reference only and shall not affect the construction of any provision of the Plan. 4

In so acting, we have examined such certificates, records, statutes and other documents as we have deemed relevant in rendering this opinion. As to matters of fact, we have relied on representations of officers of the Company. In our examination, we have assumed the genuineness of documents submitted to us as originals and the conformity with the originals of all documents submitted to us as copies thereof. Based on the foregoing, it is our opinion that such of the 75,000 shares of Common Stock covered by the Registration Statement as are issued by the Company to participants under the Plan, when issued in accordance with the terms of the Plan, including approval of the Plan by the Company's stockholders in accordance with Section 4 of the Plan, will be validly issued, fully paid and nonassessable shares of Common Stock. The opinion set forth above is limited to Pennsylvania law. We hereby consent to the filing of this opinion as Exhibit 5 to the Registration Statement. In giving such opinion, we do not thereby admit that we are acting within the category of persons whose consent is required under Section 7 of the Act or the rules or regulations of the Securities and Exchange Commission thereunder. Very truly yours, /s/ WOLF, BLOCK, SCHORR and SOLIS-COHEN LLP
