Ladies and Gentlemen

We have acted as German legal advisers to Spark Networks SE, Munich, a European stock corporation (Societas Europaea) (the “Company”), as to matters of German law in connection with the issuing by the Company of 46,519 ordinary no par value registered shares of the Company, each representing a notional amount of € 1.00 of the Company’s share capital, (the “Option Shares”).

The Option Shares have been created by a capital increase from authorized capital as follows: The administrative Board of the Company (the “Administrative Board”) has been authorized by resolution of the shareholders’ meeting on October 25, 2017 to increase the Company’s share capital on one or several occasions on or before October 31, 2022, by not more than EUR 640,000.00 in exchange for contributions in cash and/or in kind, by issuing new ordinary no-par-value registered shares (the “Authorized Capital 2017”). The Authorized Capital 2017 has been registered with the commercial register of the Company on November 7, 2017 and the Company’s articles of association have been amended accordingly in sec. 4 para. 3.

On June 26, 2019 the Administrative Board resolved to make use of the Authorized Capital 2017 and to increase the registered share capital of then EUR 1,316,866.00 by EUR 46,519.00 to EUR 1,363,385.00, by way of issuance of the Option Shares (i.e. 46,519 new ordinary no-par value registered shares, each representing a notional amount of € 1.00 of the Company’s registered share capital) in return for certain contributions in kind (the “Option Shares Capital Increase”). The Option Shares Capital Increase has been registered with the commercial register of the Company on July 2, 2019.

We have been informed that the Company intends to deliver up to 41,867 of the Option Shares to certain participants of the Company’s current and future Virtual Stock Option Plans (the “VSOP Option Shares”). The VSOP Option Shares may be delivered in the form of American depository shares representing the right to receive such VSOP Option Shares (the “ADS”).
