The Initial Shareholders are the sole shareholders of SSU as of the date of this Agreement. SSU is active in the sports commerce and tech platform business focusing on the bike, tennis, outdoor and team sports sector.

SSU intends to enter into a series of transactions (the “Business Combination”) with, among other entities, Yucaipa, an entity which is listed on the New York Stock Exchange (the “NYSE”), for purposes of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination as further described under recital (J) below.

On or around the date of this Agreement, SISH and SSU will enter into a business combination agreement with Yucaipa and several other entities substantially in the form as attached hereto as Exhibit A (the “BCA”) setting forth the terms of the Business Combination.

SIGNA Sport Online GmbH, SIGNA AppVentures GmbH, Tennis-Point GmbH and Score Invest SAS are, among others, certain subsidiaries of SSU. The Minority Shareholders hold certain direct or, through SIGNA Beteiligung I UG (haftungsbeschränkt) & Co. KG as pooling vehicle (the “Pooling Vehicle”), indirect minority interests in such SSU subsidiaries as set forth in Exhibit B (the “Minority Shareholdings”). Pursuant to certain agreements entered into by the Minority Shareholders with inter alios SISH and the Company (the “Roll-Up Agreements”) prior to the date hereof, the Minority Shareholders have agreed and undertaken, after signing of the BCA and prior to the Share Exchange, to contribute the Minority Shareholdings to SSU against issuance of new shares in SSU to the Minority Shareholders by way of a capital increase in kind of the share capital of SSU (the “Roll-up”). Prior to such Roll-up, the Pooling Vehicle shall be dissolved and the Company Shares held by the Pooling Vehicle on behalf of the Minority Shareholders shall be transferred to the respective Minority Shareholders (the “Dissolution”) and such transferred Company Shares will also be subject to the Roll-up. The Roll-up shall be completed after signing of the BCA and in any event in advance of the Share Exchange.

The Company, as borrower, entered into a EUR 50,000,000 convertible loan agreement with SISH, as original lender, on 20 December 2019 (notarial roll of deeds no. 461/2019 by public notary Dr. Thorsten Reinhard, Frankfurt am Main) (the “SISH Convertible Loan Agreement”). Under a certain purchase and contractual assignment agreement (Vertragsübernahme) dated 14 December 2020 (notarial roll of deeds no. 348/2020 by public notary Dr. Thorsten Reinhard, Frankfurt am Main), the SISH Convertible Loan Agreement was transferred and assigned from SISH to BBL in a partial amount of EUR 10,000,000 (plus accrued interest) whereby BBL has the right

SSU, as borrower, entered into a EUR 25,000,000 convertible loan agreement with RAG-S (formerly: RAG-S Lending SCS, SICAV RAIF), as original lender, on 20 December 2019 (notarial roll of deeds no. 461/2019 by public notary Dr. Thorsten Reinhard, Frankfurt am Main) (the “RAG-S Convertible Loan Agreement”, and together with the SISH Convertible Loan Agreement, the “Convertible Loan Agreements”).

Pursuant to certain irrevocable commitments entered into by the Convertible Loan Lenders with SISH on or prior to the date hereof, the Convertible Loan Lenders have agreed and undertaken, after signing of the BCA and prior to closing of the Business Combination, to convert the entire loan amount granted to SSU under the Convertible Loan Agreements (plus accrued interest) into new common shares in SSU, in the nominal amount of EUR 1.00 per share, by way of a capital increase in kind of the share capital of SSU (the “Conversion”). The Conversion shall be completed sufficiently in advance of the Business Combination.

Upon the occurrence of the Roll-up and the Conversion, the Minority Shareholders and the Convertible Loan Lenders, respectively, will become shareholders of SSU (the “Future Shareholders”, and together with the Initial Shareholders, the “Shareholders”).

SISH, with the participation of SSU, has entered into certain investment agreements with the SSU minority shareholders, i.e. (i) with AEON on 20 December 2018 (notarial roll of deeds no. 420/2018 by public notary Dr. Thorsten Reinhard, Frankfurt am Main), (ii) with Evergrow Asia Ltd. under participation of Harng Central Department Store Ltd. on 20 December 2018 (notarial roll of deeds no. 422/2018 by public notary Dr. Thorsten Reinhard, Frankfurt am Main) and (iii) with RVV and RVLV on 16 September 2019 (notarial roll of deeds no. 296/2019 by public notary

Pursuant to the BCA, the Business Combination will, subject to the terms and conditions thereof (including any amendments, supplements or other modifications thereto in accordance with its terms) and among other transactions contemplated thereby, be implemented substantially as follows:

It is in the Shareholders’ interest that the Transaction, including for the avoidance of doubt the Conversion and the Roll-up, is implemented substantially as described above and in the BCA.

In order to facilitate the implementation of the Transaction each of the Initial Shareholders, Convertible Loan Lenders and Minority Shareholders has (i), prior to the date hereof, duly executed and delivered powers of attorney to SISH or to another recipient of their choice, substantially in the form attached hereto as Exhibit D and has (ii) duly executed and delivered or will duly execute and deliver powers of attorney to NautaDutilh N.V. or another recipient of their choice, substantially in the form attached hereto as Exhibit E, or in the form of a sub-power of attorney with the respective scope, respectively, permitting the respective authorized person (i) to execute and deliver any agreements to which such Shareholder is a party to in connection with the Transaction (including, but not limited to, the Dutch Deeds of Issue or the German Share Transfer Deed, each such term as defined in the BCA), (ii) to take all necessary or desirable actions on behalf of such Shareholder in connection with the transactions contemplated under and as set forth in the BCA and the “Transaction Documents” (as such term is defined in the BCA) to the extent applicable to such Shareholder (including, for the avoidance of doubt, the execution of this Agreement on each Shareholder’s behalf), (iii) to convene and conduct shareholders’ meetings of the Company (including participating and exercising voting rights attached to the Company Shares) in accordance with the governing documents of the Company and for the purpose of obtaining the requisite consent for the Share Exchange and (iv) to support the transactions contemplated by the BCA and the other Transaction Documents (including by way of restrictions on the sale, disposition or transfer of the Company Shares held by such Shareholder).
