AMENDMENT NO. 4 TO AMENDED AND RESTATED CREDIT AGREEMENT AND OMNIBUS AMENDMENT TO CREDIT DOCUMENTS

This Amendment No. 4 to Amended and Restated Credit Agreement and Omnibus Amendment to Credit Documents (this “Agreement”) dated as of May 23, 2013 (the “Effective Date”) is among Forum Energy Technologies, Inc. (the “Borrower”), the Guarantors, the Lenders party hereto, the Issuing Lenders party hereto, and Wells Fargo Bank, National Association, as administrative agent (in such capacity, the “Administrative Agent”).

A.    The Borrower, the Administrative Agent, the Issuing Lenders party thereto from time to time, the Lenders party thereto from time to time and Wells Fargo Bank, National Association, as the swing line lender, are parties to that certain Amended and Restated Credit Agreement dated as of October 4, 2011, as amended by that certain Amendment No. 1 to Amended and Restated Credit Agreement dated as of March 27, 2012, that certain Agreement and Amendment No. 2 to Amended and Restated Credit Agreement dated as of July 27, 2012 (“Amendment No. 2”), and that certain Agreement and Amendment No. 3 to Amended and Restated Credit Agreement dated as of November 20, 2012 (as so amended, the “Credit Agreement”).

B.    The Borrower has requested that the Lenders make certain amendments to the Credit Agreement and certain other Credit Documents to address permitted investments and recent legal developments related to swap obligations, in each case, as set forth below, and the Lenders party hereto are willing to make such amendments.

C.    Furthermore, the description of the “Note Contribution” and “Intercompany Note” in Amendment No. 2 do not accurately describe the intercompany obligations that were contributed by the Borrower to the Foreign Finance Subsidiary described therein and, and therefore, the Borrower has requested that the Lenders amend Amendment No. 2 (and as a result, the Credit Agreement) and waive any non-compliance with the terms of the Credit Documents in respect of such Note Contribution and the Intercompany Note, in each case, as set forth below, and the Lenders party hereto are willing to make such amendments and grant such waiver on the terms and conditions set forth herein.

NOW, THEREFORE, the parties hereto hereby agree as follows:

Section 1.Defined Terms; Other Definitional Provisions. As used in this Agreement, each of the terms defined in the opening paragraph and the Recitals above shall have the meanings assigned to such terms therein. Each term defined in the Credit Agreement and used herein without definition shall have the meaning assigned to such term in the Credit Agreement, unless expressly provided to the contrary. Article, Section, Schedule, and Exhibit references are to Articles and Sections of, and Schedules and Exhibits to, this Agreement, unless otherwise specified. The words “hereof”, “herein”, and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The term “including” means “including, without limitation,”. Paragraph headings have been inserted in this Agreement as a matter of convenience for reference only and it is agreed that such paragraph

headings are not a part of this Agreement and shall not be used in the interpretation of any provision of this Agreement.

Section 2.    Amendments to Credit Agreement.

(a)    Section 1.1 of the Credit Agreement is hereby amended by deleting the definitions of “Acquisition”, “Non-Credit Party Obligations” and “Secured Obligations” in their entirety and replacing them with the following:

(b)    Section 1.1 of the Credit Agreement is hereby amended by adding each of the following definitions thereto in the appropriate alphabetical order:

“Amendment No. 4 Effective Date” means, May 23, 2013.

“Excluded Swap Obligations” means, with respect to any Credit Party, any Swap Obligation if, and to the extent that, all or a portion of the guarantee of such Credit Party of, or the grant by such Credit Party of a security interest to secure, such Swap Obligation (or any guarantee thereof) is or becomes illegal under the Commodity Exchange Act or any rule, regulation or order of the Commodity Futures Trading Commission (or the application or official interpretation of any thereof) by virtue of such Credit Party’s failure for any reason to constitute an “eligible contract participant” as defined in the Commodity Exchange Act and the regulations thereunder at the time the guarantee of such Credit Party or the grant of such security interest becomes effective with respect to such Swap Obligation. If a Swap Obligation arises under a master agreement governing more than one swap, such exclusion shall apply only to the portion of such Swap Obligation that is attributable to swaps for which such guarantee or security interest is or becomes illegal.

(c)    Section 5.8(a) of the Credit Agreement is hereby amended by (i) deleting the “and” after clause (ii) thereof, (ii) replacing the period at the end of clause (iii) thereof with “; and” and (iii) adding to the end thereof the following clause:

(h)    Section 6.8(j) of the Credit Agreement is hereby amended by inserting immediately after the term “joint venture” the phrase “(that is not a Subsidiary)”.

(i)    Section 7.6 of the Credit Agreement is hereby amended by adding to the end thereof the following sentence:

(a)    The Security Agreement is hereby amended by:

(1)    Inserting at the end of Section 2.2(a) thereof the following sentence:

(b)    The Guaranty is hereby amended by:

(1)    Inserting at the end of Section 2(a) thereof the following sentence:

(2)    Adding at the end thereof the following new Section 22:

(c)    Effective as of the date the Amendment No. 2 was made effective, Amendment No. 2 is hereby amended by replacing clause (iv) in recital B found therein in its entirety with the following recital:

(d)    Effective as of the date the Amendment No. 2 was made effective, the parties hereto hereby acknowledge and agree that (i) the term “Intercompany Note” as used in Amendment No. 2 and in the Credit Agreement shall mean only such obligations of FET Global Holdings Limited under the Amended and Restated Intercompany Note dated as of October 4, 2011 referred to in Amendment No. 2 (the “Subject Note”) and not any other obligations of any other maker thereunder, (ii) the release of Liens provided under Amendment No. 2 relate solely to the obligations of FET Global Holdings Limited under the Subject Note and not with respect to any other maker thereunder,

and (iii) such release under the Security Documents is effective as of the effective date of the Note Contribution. To the extent any Lien created by the Security Documents in the Subject Note as to obligations thereunder of any maker other than FET Global Holdings Limited is determined to have been released notwithstanding the foregoing agreements, each Credit Party hereby pledges, hypothecates, assigns, mortgages, delivers and transfers to the Administrative Agent, for the ratable benefit of each Secured Party, and hereby grants to the Administrative Agent, for the ratable benefit of each Secured Party, a continuing security interest in all of such Credit Party’s right, title and interest in, to and under, the Subject Note as to obligations thereunder of any maker other than FET Global Holdings Limited, whether now owned or hereafter acquired by such Credit Party, and whether now owned or hereafter existing or arising, with such collateral and security interest being, in all respects, subject to the terms of the Security Agreement.

(e)    Subject to the terms and conditions set forth herein, the Lenders hereby waive any non-compliance by the Credit Parties with the terms of any Credit Document that may have occurred solely and as a result of (i) the partial (rather than full) contribution of the Subject Note as contemplated by Amendment No. 2 and the other Credit Documents and (ii) the return of the Subject Note from the Administrative Agent to the Borrower (the “Subject Waivers”). The undersigned Lenders hereby confirm and agree that the contribution by the Borrower to Forum Luxembourg Limited of the portion of the indebtedness owed by FET Global Holdings Limited to the Borrower under the Subject Note constitutes the “Note Contribution” as defined in Amendment No. 2 and is permitted under Section 6.3(j) of the Credit Agreement, and that no Default or Event of Default exists with respect to the Subject Waivers. Notwithstanding the foregoing, the execution of this Agreement shall not be deemed to be, except as set forth above, a waiver of, or consent by the Administrative Agent or any Lender to, any non-compliance with the terms of the Credit Agreement or any other Credit Document. The description herein of the Subject Waivers is based upon the information provided to the Lenders on or prior to the date hereof and shall not be deemed to exclude the existence of any Defaults or Events of Default arising as a result of matters not specifically addressed herein. The failure of the Lenders to give notice to any Credit Party of any such Defaults or Events of Default is not intended to be nor shall be a waiver thereof. For the avoidance of doubt, each Credit Party also agrees and acknowledges that the waiver provided above shall not operate as a waiver of or otherwise prejudice any rights or remedies available under contract or under applicable law, other than as expressly provided for in this paragraph (e).

Section 4.    Representations and Warranties. Each Credit Party represents and warrants that: (a) after giving effect to this Agreement, the representations and warranties contained in the Credit Agreement, as amended hereby, and the representations and warranties contained in the other Credit Documents are true and correct in all material respects (except that such materiality qualifier shall not be applicable to any representations and warranties that already are qualified or modified by materiality in the text thereof) on and as of the Effective Date as if made on as and as of such date, except that any such representation or warranty which by its terms is made as of a specified date is true and correct in all material respects (except that such materiality qualifier shall not be applicable to any representations and warranties that already are qualified or modified by materiality in the text thereof) as of such specified date; (b) after giving effect to this Agreement, no Default has occurred and is continuing; (c) the execution, delivery and performance of this Agreement are within such Credit Party’s corporate, partnership or limited liability company power and authority, as applicable, and have been duly authorized by appropriate governing action and

proceedings; (d) this Agreement constitutes the legal, valid, and binding obligation of such Credit Party enforceable in accordance with its terms, except as limited by applicable bankruptcy, insolvency, reorganization, moratorium, or similar laws affecting the rights of creditors generally and general principles of equity; (e) there are no governmental or other third party consents, licenses and approvals required in connection with the execution, delivery, performance, validity and enforceability of this Agreement; and (f) the Liens under the Security Documents are valid and subsisting and secure the Secured Obligations.

Section 5.    Conditions to Effectiveness. This Agreement shall become effective on the Effective Date and enforceable against the parties hereto upon the receipt by the Administrative Agent of (a) this Agreement duly executed by the Borrower, the Guarantors, the Administrative Agent and the Lenders, and (b) a copy of the Second Amended and Restated Intercompany Note made as of May 14, 2013, effective as of August 1, 2012, executed by the makers thereof in favor of the Borrower (the “New Note”), which amends and restates the Subject Note, and a copy of a duly executed note allonge thereto endorsing such note to the Administrative Agent as a collateral pledge thereof under the Security Agreement (the “Allonge”).

(a)    The Borrower acknowledges that on the date hereof all outstanding Obligations are payable in accordance with their terms and the Borrower waives any defense, offset, counterclaim or recoupment with respect thereto.

(b)    The Borrower, the Administrative Agent, the Issuing Lenders party hereto and the Lenders party hereto do hereby adopt, ratify, and confirm the Credit Agreement, as amended hereby, and acknowledge and agree that the Credit Agreement, as amended hereby, is and remains in full force and effect, and the Borrower and the Guarantors acknowledge and agree that their respective liabilities and obligations under the Credit Agreement, as amended hereby, and the Guaranty, are not impaired in any respect by this Agreement.

(c)    From and after the Effective Date, all references to the Credit Agreement, the Guaranty, the Security Agreement or Amendment No. 2 in the Credit Documents shall mean the Credit Agreement, the Guaranty, the Security Agreement or Amendment No. 2, as the case may be, as amended by this Agreement.

(d)    This Agreement is a Credit Document for the purposes of the provisions of the other Credit Documents.

(e)    On or prior to May 31, 2013, the Borrower agrees to deliver to the Administrative Agent the originals of the New Note and Allonge.

requirement by such Guarantor under the Guaranty in connection with the execution and delivery of amendments, consents or waivers to the Credit Agreement, the Notes or any of the other Credit Documents.

Section 8.    Counterparts. This Agreement may be signed in any number of counterparts, each of which shall be an original and all of which, taken together, constitute a single instrument.

Section 10.    Invalidity. In the event that any one or more of the provisions contained in this Agreement shall for any reason be held invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of this Agreement.

Section 11.    Governing Law. This Agreement shall be deemed a contract under, and shall be governed by, and construed and enforced in accordance with, the laws of the State of New York applicable to contracts made and to be performed entirely within such state, without regard to conflicts of laws principles (other than Section 5-1401 and Section 5-1402 of the General Obligations Law of the State of New York).
