Re:  The Chemours Company – Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as counsel to The Chemours Company, a Delaware corporation (the “Company”), and the guarantors listed on Schedule I hereto (the “Covered Guarantors”) and Schedule II hereto (the “Other Guarantors,” and together with the Covered Guarantors, the “Guarantors”), in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), of a registration statement on Form S-3 (the “Registration Statement”), as amended by Post-Effective Amendment No. 1, relating to the offer from time to time, together or separately and in one or more series (if applicable), of an indeterminate amount of (i) debt securities of the Company (the “Debt Securities”), which may be fully and unconditionally guaranteed on a joint and several senior unsubordinated basis by each of the Guarantors pursuant to the guarantees (the “Guarantees”) contained in the applicable Indenture (as defined herein), (ii) warrants of the Company (the “Warrants”), (iii) shares of the Company’s preferred stock, par value $0.01 per share (the “Preferred Stock”), and (iv) shares of the Company’s common stock, par value $0.01 per share (the “Common Stock,” and together with the Debt Securities, the Guarantees, the Warrants and the Preferred Stock, the “Securities”). The Securities being registered under the Registration Statement will be offered by the Company on a continuous or delayed basis pursuant to the provisions of Rule 415 under the Securities Act. The Registration Statement was filed by the Company with the Commission on May 9, 2017 and became effective automatically under the Securities Act pursuant to Rule 462(e) thereunder.

The Debt Securities are to be issued from time to time pursuant to a senior indenture (the “Senior Indenture”) to be entered into between the Company and U.S. Bank National Association, as trustee (the “Trustee”), as amended or supplemented, or pursuant to a subordinated indenture (the “Subordinated Indenture,” and together with the Senior Indenture, the “Indentures”) to be entered into between the Company and the Trustee, as amended or supplemented.

The Warrants are to be issued from time to time pursuant to (i) one or more indentures to be entered into between the Company and a trustee named therein or (ii) one or more warrant agreements (each, a “Warrant Agreement”) to be entered into by the Company and one or more institutions, as warrant agents (each, a “Warrant Agent”), each to be identified in the applicable Warrant Agreement.

In connection with this opinion, we have examined such corporate records, documents, instruments, certificates of public officials and of the Company and the Guarantors and such questions of law as we have deemed necessary for the purpose of rendering the opinions set forth herein. We also have examined the Registration Statement, including the form of Senior Indenture filed therewith.

In such examination, we have assumed the genuineness of all signatures and the authenticity of all items submitted to us as originals and the conformity with originals of all items submitted to us as copies.

With respect to our opinion in paragraph 2 below relating to the Other Guarantors, we have relied upon the opinion of Locke Lord LLP of even date herewith with respect to certain matters of the laws of the State of Texas, we have relied upon the opinion of Ballard Spahr LLP of even date herewith with respect to certain matters of the laws of the State of Pennsylvania, and we have relied upon the opinion of Butler Snow LLP, of even date herewith with respect to certain matters of the laws of the State of Mississippi.

The opinions hereinafter expressed are subject to the following qualifications and exceptions:

(i)           the effect of bankruptcy, insolvency, reorganization, arrangement, moratorium or other similar laws relating to or affecting the rights of creditors generally, including, without limitation, laws relating to fraudulent transfers or conveyances, preferences and equitable subordination;

(ii)          limitations imposed by general principles of equity upon the availability of equitable remedies or the enforcement of provisions of any Securities, and the effect of judicial decisions which have held that certain provisions are unenforceable where their enforcement would violate the implied covenant of good faith and fair dealing, or would be commercially unreasonable, or where their breach is not material; and

(iii)         our opinion is based upon current statutes, rules, regulations, cases and official interpretive opinions, and it covers certain items that are not directly or definitively addressed by such authorities.

Based on the foregoing, and subject to the further assumptions and qualifications set forth below, it is our opinion that:

1.            When the terms of the Debt Securities of the Company to be issued under the applicable Indenture and of their issuance and sale have been duly established in conformity with the applicable Indenture so as not to violate any applicable law or result in a default under or breach of any agreement or instrument binding upon the Company, and so as to comply with any requirement or restriction imposed by any court or governmental body having jurisdiction over the Company, and when the Debt Securities have been duly executed and authenticated in accordance with the applicable Indenture and issued and sold as contemplated in the Registration Statement, and if all the foregoing actions are taken pursuant to the authority granted in the resolutions of the Board of Directors of the Company, the Debt Securities will be valid, binding and enforceable obligations of the Company, entitled to the benefits of the applicable Indenture.

2.            When the terms of the Debt Securities of the Company to be issued under the applicable Indenture described above and of their issuance and sale have been duly established in conformity with the applicable Indenture so as not to violate any applicable law or result in a default under or breach of any agreement or instrument binding upon the Company, and so as to comply with any requirement or restriction imposed by any court or governmental body having jurisdiction over the Company, and when the Debt Securities have been duly executed and authenticated in accordance with the applicable Indenture and issued and sold as contemplated in the Registration Statement, and if all the foregoing actions are taken pursuant to the authority granted in the resolutions of the Board of Directors of the Company, the Guarantees will be valid, binding and enforceable obligations of the Guarantors.

3.            When the terms of the Warrants of the Company to be issued under the form of indenture described above (the “Indenture Warrants”) and of their issuance and sale have been duly established in conformity with the related indenture so as not to violate any applicable law or result in a default under or breach of any agreement or instrument binding upon the Company, and so as to comply with any requirement or restriction imposed by any court or governmental body having jurisdiction over the Company, and when the Indenture Warrants have been duly executed and authenticated in accordance with the indenture and issued and sold as contemplated in the Registration Statement, and if all the foregoing actions are taken pursuant to the authority granted in the resolutions of the Board of Directors of the Company, the Indenture Warrants will constitute valid and legally binding obligations of the Company. The Warrants covered by the opinion in this paragraph include any warrants of the Company that may be issued under an indenture and as part of the Units or upon exercise or otherwise pursuant to the terms of any other Securities.

4.            When the terms of the warrant agreements under which certain of the Warrants of the Company are to be issued have been duly established and the warrant agreements have been duly executed and delivered, when the terms of such Warrants and of their issuance and sale have been duly established in conformity with the applicable warrant agreement and when such Warrants have been duly executed and authenticated in accordance with the applicable warrant agreement and issued and sold as contemplated in the Registration Statement, and if all the foregoing actions are taken pursuant to the authority granted in the resolutions of the Board of

Directors of the Company and so as not to violate any applicable law or result in a default under or breach of any agreement or instrument binding upon the Company and so as to comply with any requirement or restriction imposed by any court or governmental body having jurisdiction over the Company, such warrants will constitute valid and legally binding obligations of the Company. The Warrants covered by the opinion in this paragraph include any warrants of the Company that may be issued as part of the Units or upon exercise or otherwise pursuant to the terms of any other Securities, but they do not include any Indenture Warrants.

5.            When appropriate certificates of designations relating to the class or series of shares of Preferred Stock to be sold under the Registration Statement (the “Certificates of Designations”) have been duly approved by the Board of Directors of the Company or a duly authorized committee thereof and the Certificates of Designations have been filed with and accepted for record by the Secretary of State of the State of Delaware, when the terms of the sale and issuance of the such class or series of Preferred Stock have been duly established in accordance with the Company’s Amended and Restated Certificate of Incorporation (the “Amended and Restated Certificate of Incorporation”) and the Company’s Amended and Restated Bylaws (the “Amended and Restated Bylaws”), which terms do not violate any applicable law or result in a default under or breach of any agreement or instrument binding upon the Company and comply with any requirement or restriction imposed by any court or government body having jurisdiction over the Company, and when the shares of Preferred Stock of such class or series have been duly issued and sold as contemplated by the Registration Statement and consideration therefore has been received by the Company, such shares of Preferred Stock will be duly authorized, validly issued, fully paid and nonassessable.

6.            When the terms of the sale and issuance of the shares of Common Stock have been established in conformity with the Amended and Restated Certificate of Incorporation and the Amended and Restated Bylaws, which terms do not violate any applicable law or result in a default under or breach of any agreement or instrument binding upon the Company and comply with any requirement or restriction imposed by any court or government body having jurisdiction over the Company, and when the shares of Common Stock have been duly issued and sold as contemplated by the Registration Statement and consideration therefore has been received by the Company, such shares of Common Stock will be duly authorized, validly issued, fully paid and nonassessable.
