We have acted as special counsel to Frank’s International N.V., a Netherlands a public company with limited liability (naamloze vennootschap), registered with the Commercial Register under number 34241787 (the “Company”), with respect to certain legal matters in connection with the preparation and filing of a registration statement on Form S-4 (the “Registration Statement”) by the Company under the Securities Act of 1933, as amended (the “Securities Act”), relating to the registration of the issuance by the Company of up to 5,782,392 warrants of the Company to purchase shares of common stock of the Company as specified in the Registration Statement (each, a “Warrant”). The Warrants are being issued pursuant to a Proxy Statement/Prospectus (the “Prospectus”) forming a part of the Registration Statement.

In connection with the opinion expressed herein, we have examined originals or copies, certified or otherwise identified to our satisfaction, of (i) the Agreement and Plan of Merger (“Merger Agreement”) by and among the Company, New Eagle Holdings Limited and Expro Group Holdings International Limited (“Expro”), dated as of March 10, 2021 that is filed as Exhibit 2.1 to the Registration Statement; (ii) the Warrant Agreement, dated February 5, 2018 between Expro and Cortland Capital Market Services LLC, as Warrant Agent (such agent, the “Warrant Agent” and such agreement, the “Original Warrant Agreement”), (iii) the Form of Warrant Agreement that, subject to the terms and conditions contained in the Merger Agreement and the Original Warrant Agreement, would be entered into as of the Effective Time (as defined in the Merger Agreement) between the Company and the Warrant Agent that is filed as Exhibit 10.4 to the Registration Statement (the “Warrant Agreement”); (iv) the Registration Statement; (v) the Form of Class A Warrant Certificate and the Form of Class B Warrant Certificate attached as exhibits to the Warrant Agreement; and (vi) such other certificates, statutes and other instruments and documents as we considered appropriate for purposes of the opinion hereafter expressed. We have also reviewed such questions of law as we have deemed necessary or appropriate. As to matters of fact relevant to the opinion expressed herein, and as to factual matters arising in connection with our examination of corporate documents, records and other documents and writings, we relied upon certificates and other communications of corporate officers of the Company, without further investigation as to the facts set forth therein.

We have further assumed that each of the documents identified in clauses (i) through (v) of the preceding paragraph will be entered into, adopted or filed as appropriate.

Based upon the foregoing, and subject to the qualifications, assumptions and limitations stated herein, we are of the opinion that the Warrants, when and if issued and delivered in accordance with the terms of the Merger Agreement, and assuming the due authorization, execution and delivery of such Warrants by the Company and the Warrant Agent, will constitute the legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally, and subject, as to enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity).
