At the date of this invitation the Company's capital is divided into 35,740,896 common shares incorporating 35,740,896 voting rights in total. Whoever appears to be a shareholder in the records of the Dematerialized Securities System (DSS), managed by the "Hellenic Central Securities Depository SA"(ATHEXCSD) where the securities (shares) of the Company are kept, is entitled to participate in the General Meeting. The capacity of the shareholder must exist at the beginning of the fifth (5th) day prior to the date of the General Meeting of 18 June 2021, i.e., at the beginning of 13 June 2021 (the "Record Date"). The above Record Date is also valid in case of postponed or repeat meeting, provided that such postponed or repeat meeting is not more than thirty (30) days away from the Record Date. The shareholder capacity at the Record Date will be proved through the Company's direct electronic linkup with the records of the DSS. In case of non‐compliance with the provisions of article 124 of Law 4548/2018, said shareholder shall attend the General Meeting only if the General Meeting allows it. It is hereby noted that the exercise of said participation and voting rights does not require the block of the beneficiary's shares nor the observance of any other similar procedure, which limits the ability to sell and transfer shares during the period between the Record Date and the date of the General Meeting.

In case the required quorum is not ascertained, with regard to the items of the agenda, the shareholders are invited on 9 July, 2021, day of the week Friday at 16:00 p.m. at the Company's seat, in Municipality of Kallithea, Attica and, more specifically, in the office building of its subsidiary company under the name "Uni Systems S.M.S.A." at 19‐23 Al.

Procedure for voting through proxy/ies:

Every shareholder attends the General Meeting and votes either in person or through proxies. Each shareholder may appoint up to three (3) proxies. However, if the shareholder holds Company's shares that appear in more than one securities' accounts, this limitation does not prevent the shareholder from appointing different proxies for the shares that appear in each securities account in relation to the General Meeting. A proxy that acts for more shareholders may vote differently for every shareholder. Legal entities participate in the General Meeting by appointing up to three (3) natural persons as their proxies. The shareholder may appoint a proxy for a single general meeting or for all meetings that take place within a certain time. The proxy votes in accordance with the instructions of the shareholder, if any, and is obliged to file the voting instructions for at least one (1) year, from the date of the General Meeting, or in case of its postponement, of the last repeat meeting in which he used his power of attorney. The proxy is obliged to disclose to the Company before the commencement of the General Meeting every

specific fact, which could be useful to shareholders in order to evaluate the risk of the proxy serving interests other than the shareholder's interests. Conflict of interest may arise mainly in cases when the proxy is: a) a shareholder that exercises the control of the Company or another legal entity or an entity controlled by that shareholder, b) a member of the Board of Directors or of the general management team of the Company or of a shareholder controlling the Company, or of another legal entity or of an entity controlled by a shareholder controlling the Company, c) an employee or certified auditor of the Company or of a shareholder controlling the Company, or of another legal entity or of an entity controlled by a shareholder controlling the Company d) the spouse or a relative of first degree of one of the natural persons mentioned in cases (a) to (c). The appointment and revocation of the shareholder's proxy is done in writing or electronically and is notified to the Company, at least three (3) days prior to the scheduled date of the General Meeting. The Company has made available on its website (www.quest.gr) on the internet, the form used for the appointment of a proxy. The aforementioned form, completed and signed, must be submitted by the shareholder to the Company Offices, at 2A Argyroupoleos ‐ Kallithea Attica (Shareholder Services, contact person Mr. Dimitrios Papadiamantopoulos) or must be sent by fax to 211 999 4530 or by email to [e-mail], at least three (3) days prior to the date of the General Meeting or any Repeat Meeting.
