We have acted as special counsel to XWELL, Inc., a Delaware corporation (the “Company”), in connection with its registration under the Securities Act of 1933, as amended (the “Securities Act”), by means of a registration statement on Form S-8 (the “Registration Statement”), of an aggregate of 7,500,000 additional shares of the Company’s common stock, par value $0.01 per share (the “Shares”), which may be issued pursuant to the XWELL, Inc. 2020 Equity Incentive Plan, as amended, formerly known as the XpresSpa Group, Inc. 2020 Equity Incentive Plan (the “Plan”).

We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such other corporate records, agreements and instruments of the Company, statements and certificates of public officials and officers of the Company, and such other documents, records and instruments, and we have made such legal and factual inquiries, as we have deemed necessary or appropriate as a basis for us to render the opinions hereinafter expressed. In our examination of the foregoing, we have assumed the genuineness of all signatures, the legal competence and capacity of natural persons, the authenticity of documents submitted to us as originals and the conformity with authentic original documents of all documents submitted to us as copies or by facsimile or other means of electronic transmission, or which we obtained from the Securities and Exchange Commission’s (“SEC”) Electronic Data Gathering, Analysis and Retrieval system (“Edgar”) or other sites maintained by a court or governmental authority or regulatory body and the authenticity of the originals of such latter documents. If any documents we examined in printed, word processed or similar form have been filed with the SEC on Edgar or such court or governmental authority or regulatory body, we have assumed that the document so filed is identical to the document we examined except for formatting changes. When relevant facts were not independently established, we have relied without independent investigation as to matters of fact upon statements of governmental officials and upon representations made in or pursuant to the certificates and statements of appropriate representatives of the Company.
