Re: Registration Statement on Form S-8

Ladies and Gentlemen:

We have acted as Israeli counsel for Naytax Ltd., an Israeli company (the “Company”), in connection with the registration statement on Form S-8 (the “Registration Statement”) filed by the Company with the United States Securities and Exchange Commission (the “SEC”) on the date hereof pursuant to the United States Securities Act of 1933, as amended (the “Securities Act”), relating to (i) 105,870 of the Company’s ordinary shares, par value NIS 0.001 per share ("Ordinary Shares"), issuable upon the exercise of options currently outstanding under the Company's 2013 Share Option Plan (the "2013 Plan") and (ii) 4,594,130 of the Company’s ordinary shares, par value NIS 0.001 per share ("Ordinary Shares"), issuable upon (a) the exercise of options currently outstanding under the Company's Global Equity Incentive Plan (2018) (the "2018 Plan"), (b) the vesting of restricted stock units ("RSU's") current outstanding under the 2018 Plan or (c) the exercise of options or vesting of RSU's that may be granted in the future under the 2018 Plan, including ordinary shares subject to options previously granted under the 2013 Plan or options or RSU's previously or to be granted under the 2018 Plan that are not exercised by the grantee within the exercise period and become available again for future grant under the 2018 Plan. Ordinary Shares issuable under either the 2013 Plan or the 2018 Plan shall be referred to as the “Shares”.

In connection with this opinion, we have examined originals or copies, certified or otherwise identified to our satisfaction, of the 2013 Plan and 2018 Plan, the Registration Statement, the Company’s Amended and Restated Articles of Association (the “Articles”) and such other agreements, certificates, resolutions, minutes and other statements of corporate officers and other representatives of the Company and other documents as we have deemed necessary or appropriate as a basis for this opinion.

In rendering our opinion, we have assumed the authenticity of all original documents submitted to us as certified, conformed or photographic copies thereof, the genuineness of all signatures and the due authenticity of all persons executing such documents. We have assumed the same to have been complete and accurate. We have also assumed the truth of all facts communicated to us by the Company and that all consents, minutes and protocols of meetings of the Company’s board of directors which have been provided to us are true and accurate and have been properly prepared in accordance with the Articles and all applicable laws, including, without limitation, the board of director’s approval of (i) the 2013 Plan, (ii) the 2018 Plan and (iii) the reservation of a pool of 4,700,000 Shares to be issued upon the exercise of options currently outstanding under the 2013 Plan, the exercise of options or vesting of RSU's currently outstanding under the 2018 Plan, or the exercise of options or vesting of RSU's that may be granted in the future under the 2018 Plan, including ordinary shares subject to options previously granted under the 2013 Plan or options or RSU's previously or to be granted under the 2018 Plan that are not exercised by the grantee within the exercise period and become available again for future grant under the 2018 Plan.
