Item 4. Description of Securities.

Not Applicable.

Item 5. Interests of Named Experts and Counsel.

Not applicable.

Item 6. Indemnification of Directors and Officers.

Section 721 of the New York Business Corporation Law (the “NYBCL”) provides that, in addition to indemnification provided in Article 7 of the NYBCL, a corporation may indemnify a director or officer by a provision contained in the certificate of incorporation or bylaws or by a duly authorized resolution of its shareowners or directors or by agreement, except that no indemnification may be made to or on behalf of any director or officer if a judgment or other final adjudication adverse to the director or officer establishes that his or her acts were committed in bad faith or were the result of active and deliberate dishonesty and were material to the cause of action so adjudicated, or that he or she personally gained in fact a financial profit or other advantage to which he or she was not legally entitled.

Section 722(a) of the NYBCL provides that a corporation may indemnify a director or officer made, or threatened to be made, a party to any action other than a derivative action, whether civil or criminal, against judgments, fines, amounts paid in settlement and reasonable expenses actually and necessarily incurred as a result of such action, or any appeal therein, if such director or officer acted, in good faith, for a purpose which he or she reasonably believed to be in, or, in the case the person was serving any other entity in any capacity at the request of the corporation, not opposed to, the best interests of the corporation and, in criminal actions or proceedings, in addition, had no reasonable cause to believe that his or her conduct was unlawful.

Section 722(c) of the NYBCL provides that a corporation may indemnify a director or officer made, or threatened to be made, a party in a derivative action, against amounts paid in settlement and reasonable expenses actually and necessarily incurred by him or her in connection with the defense or settlement of such action, or in connection with an appeal therein if such director or officer acted, in good faith, for a purpose which he or she reasonably believed to be in, or, in the case the person was serving any other entity in any capacity at the request of the corporation, not opposed to, the best interests of the corporation. No indemnification will be available under Section 722(c) of the NYBCL in respect of (1) a threatened or pending action that is settled or otherwise disposed of, or (2) any claim as to which such director or officer shall have been adjudged liable to the corporation, unless and only to the extent that the court in which the action was brought, or, if no action was brought, any court of competent jurisdiction, determines upon application, that, in view of all the circumstances of the case, the director or officer is fairly and reasonably entitled to indemnity for such portion of the settlement amount and expenses as the court deems proper.

Section 723 of the NYBCL specifies the manner in which payment of indemnification under Section 722 of the NYBCL or indemnification permitted under Section 721 of the NYBCL may be authorized by the corporation. It provides that indemnification by a corporation is mandatory in any case where the director or officer has been successful, whether on the merits or otherwise, in defending an action of the character described in Section 722 of the NYBCL. If the director or officer has not been successful or the action is settled, indemnification may be made only if authorized by the appropriate corporate action as set forth in Section 723.

Section 724 of the NYBCL provides that, upon application by a director or officer, indemnification may be awarded by a court to the extent authorized under Sections 722 and 723(a) of the NYBCL. Section 725 of the NYBCL contains certain other miscellaneous provisions affecting the indemnification of directors and officers.

Section 726 of the NYBCL authorizes a corporation to purchase and maintain insurance to indemnify: (1) the corporation for any obligation that it incurs as a result of the indemnification of directors and officers under the provisions of Article 7 of the NYBCL; (2) directors and officers in instances in which they may be indemnified by a corporation under the provisions of Article 7 of the NYBCL; and (3) directors and officers in instances in which they may not otherwise be indemnified by a corporation under such Article 7, on condition that the contract of insurance covering such directors and officers provides, in a manner acceptable to the New York State Superintendent of Insurance, for a retention amount and for co-insurance.

Article Thirteenth of the Restated Certificate of Incorporation, as amended, of Flowserve provides as follows:

“No director of this corporation shall be personally liable to this corporation or its shareholders for damages for any breach of duty as a director; provided, however, that, to the extent required by applicable law, the foregoing clause shall not apply to any liability of a director if a judgment or other final adjudication adverse to him establishes (i) that his acts or omissions were in bad faith or involved intentional misconduct or a knowing violation of law, (ii) that he personally gained in fact a financial profit or other advantage to which he was not legally entitled, or (iii) that his acts violated Section 719 of the New York Business Corporation Law. Any repeal or modification of this Article THIRTEENTH shall not adversely affect any right or protection of a director of the corporation existing hereunder with respect to any act or omission occurring prior to or at the time of such repeal or modification.”

Article IX of Flowserve’s By-laws, as amended and restated, provides that Flowserve shall indemnify and advance expenses to any present or future director or officer from and against any and all liabilities and expenses to the broadest and maximum extent permitted by the NYBCL as the same presently exists or to the greater extent permitted by any amendment thereafter adopted.

Flowserve has entered into indemnification agreements with its directors and officers that provide indemnification to the fullest extent permitted by the NYBCL, as well as certain additional procedural protections. The indemnification agreements provide that directors and officers will be indemnified to the fullest extent permitted by law against all expenses (including attorneys’ fees) and settlement amounts paid or incurred by them in any proceeding as directors or officers of Flowserve, including any action on account of their services as officers or directors of any other company or enterprise when they are serving in such capacities at Flowserve’s request. Flowserve must pay in advance of a final disposition of a proceeding or claim, the expenses incurred by the indemnitee no later than 10 days after receipt of an undertaking by or on behalf of the indemnitee to repay the amount of the expenses to the extent that it is ultimately determined that the indemnitee is not entitled to be indemnified by Flowserve. The indemnification agreements also provide the indemnitee with remedies in the event that Flowserve does not fulfill its obligations under the indemnification agreements.

As permitted by Section 726 of the NYBCL, Flowserve maintains policies of insurance under which its directors and officers are insured, within the limits and subject to the limitations of the policies, against specific expenses in connection with the defense of, and specific liabilities that might be imposed as a result of, actions, suits or proceedings to which they are parties by reason of being or having been directors or officers.

The preceding discussion of the NYBCL, Flowserve’s Restated Certificate of Incorporation and By-laws is not intended to be exhaustive and is qualified in its entirety by reference to the NYBCL and such documents.

Item 7. Exemption from Registration Claimed.

Not applicable.

Item 8. Exhibits.

The following are filed as exhibits to this registration statement:

Item 9. Undertakings.

(a) 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;

(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. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective 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)(1)(i) and (a)(1)(ii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Exchange Act that are incorporated by reference in the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act, 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.

(b) The undersigned registrant hereby undertakes that, for the purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) 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.

(c) Insofar as indemnification for liabilities arising under the Securities Act 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 Commission such indemnification is against public policy as expressed in the Securities 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 Securities Act and will be governed by the final adjudication of such issue.
