the following Loan Agreement (the “Agreement”) is concluded:

1. Loan Amount/ Loan Purpose

1.1 The Bank makes available to the Borrower an instalment loan

in the amount of EUR 20 million

(in words twenty million Euros) (the “Loan”).

The Loan shall be charged to account.

1.2 The purpose of the Loan is the refinancing of the EUR 19 million loan made available to Louis Renner GmbH based on a loan agreement dated July 5, 2019 {the “Existing Loan Agreement”) and otherwise for the Borrower’s general corporate purposes, incl. investments in digitalization.

2. Utilization / Non-Acceptance Penalty

2.1 The Loan is to be drawn down on 04/15/2020 (“Utilization Date”). The amount to settle any outstanding obligations for principal and interest in respect of the Existing Loan Agreement shall be provided to account IBAN DE 70 2004 0000 0614 8142 00. The remaining amount of the Loan shall be provided to account IBAN DE78 2008 0000 0381 2716 00.

2.2 To the extent the Loan has not been drawn down on the Utilization Date, the claim for disbursement shall expire and the amount of the Loan shall be reduced by the undrawn amount, subject to other arrangements made between the Borrower and the Lender. This also applies in the event that the conditions precedent have not or not fully been met at the Utilization Date.

2.3 If the Borrower does not draw down the Loan provided by the Bank in whole or in part on the Utilization Date, it shall be obliged to compensate the Bank for losses resulting from non -acceptance, to the extent it is responsible for non-acceptance.

3. Fixed-interest Periods, Interest Rate and Debit Authorisation

3.1

3.1.1 Every amount utilized under the Loan shall be charged with interest based on fixed-interest periods. For this purpose, the time period during which the Loan is outstanding is divided into fixed-interest periods of 3 months in such a way that one fixed-interest period ends on every instalment deadline. The first and/or the last fixed-interest period may have a shorter term.

A shorter term of the first fixed-interest period shall be communicated to the Bank by the Borrower in the disbursement request.

The first fixed-interest period begins on the day of the first utilization of the Loan and runs until 07/15/2020, all subsequent fixed-interest periods shall begin on the last date of the preceding fixed-interest period. The fixed-interest periods shall end on the last day of the 3-months -period. The last fixed-interest period shall end on the last day of the loan’s term at the latest

3.1.2 If the end of a fixed-interest period falls on a day that is not a banking day, then the fixed -interest period shall be extended until the following banking day, unless that day falls in the next calendar month. In this case, the fixed-interest period shall end on the immediately preceding banking day.

3.1.3 A banking day shall be any day (except Saturday and Sunday) on which commercial banks in Frankfurt am Main are open for business.

3.2 For each fixed-interest period, the Borrower shall pay interest corresponding to the 3-month -EURIBOR determined according to this No. plus a margin of 1.8 % p.a. for all amounts outstanding or utilized during this fixed-interest period in arrears on the last day of the relevant fixed-interest period. If the EURIBOR is 0% or less than 0%, the Borrower shall pay interest at a rate equal to the margin.

The Bank shall inform the Borrower of the interest rate immediately after its determination.

3-month-EURIBOR is the interest rate published on the Reuters page “EURIBOR” (or an equivalent subsequent page) for the term of the relevant fixed-interest period, which is published on the second banking day before the first day of the respective fixed-interest period.

2

Should the 3-month-EURIBOR not be displayed at the specified location two banking days prior to the beginning of a fixed-interest period, the Bank shall take the arithmetic mean from those interest rates for deposits in Euros with a comparable term and comparable amounts as a basis in lieu of the 3-month-EURIBOR for the relevant fixed-interest period, which it has received from three banks selected by the Bank that participate in the quoting of the EURIBOR. The Bank shall charge the Borrower with this arithmetic mean plus the above mentioned margin for the respective fixed-interest period, even if only less than three banks provide an interest rate.

Interest shall be calculated on the basis of the international interest method, i.e. calendar days/360 interest days per year and shall be due for payment on the last day of each term of a fixed-interest period.

3.3 In addition to the interest agreed above, the Borrower shall pay the Bank a non-recurring arrangement fee of 0.7% of the nominal amount of the Loan, due and payable five business days after the signing of this Agreement.

3.4 Unless otherwise agreed, interest and fees charged pro rata temporis shall be determined by the method of interest calculation “act/360”, i.e. the actual number of calendar days elapsed during the calculation period, divided by 360 interest days per year, shall be applied.

3.5 The Bank may debit/collect interest and fees payable according to No. 3 from any current account that the Borrower holds with the Bank.

4. Term / Repayment

4.1 The Loan shall have a term until 12/31/2026.

4.2 The Loan shall be repaid in quarterly instalments of EUR 437,500.00 and a different final instalment of EUR 8,187,500.00. The first instalment shall be due on 07/15/2020. Subsequent instalments shall be due on 06/30, 09/30, and 12/31. Amounts still outstanding on 12/31/2026 shall be repaid in a single sum plus any outstanding interest, commissions, and other fees.

7. Covenants

7.1 Minimum capital ratio

The definition and calculation of the capital ratio are set forth in the Annex I attached to this Agreement, in particular code 83006.

The Annexes referred to above for the calculation of the covenants are an integral part of the Agreement.

The basis for the calculation shall be the individual financial statement (“Bericht über die prüferische Durchsicht des Berichtspakets”) of the Borrower for the relevant financial year, using the same accounting and valuation methodology as in previous years.

The Borrower shall prove compliance with the above covenants to the Bank by submitting the financial statements and confirm such compliance in writing. The relevant documents shall each be submitted to the Bank immediately on completion and without special request, but no later than nine months after the end of the relevant financial year, and shall always be prepared in accordance with the same accounting and valuation methods. Should the accounting and valuation methods generally change, the Borrower shall notify the Bank thereof and deliver to the Bank with the first set of financial statements applying the new methods a description of any change in form and substance as may be reasonably required by the Bank to make an accurate comparison between the financial position indicated in the delivered financial statements and the previously delivered financial statements.

7.3 The Borrower is obliged to ensure that the Bank’s claims with respect to the Loan will rank at least pari passu with the claims of other creditors of the Borrower. Should the Borrower provide security to its other creditors after the date of this Agreement by operation of which those would be better secured than the Bank, the Borrower will allow beforehand or simultaneously that the Bank participates in such security in the same rank or offer equivalent and equally ranking security. The Borrower confirms to the Bank that prior to the date of this Agreement is has not provided security to other creditors with similar credit facilities by which those creditors would be ranking higher than the Bank.

Should the Borrower wish to agree financial covenants with other creditors after the date of this Agreement, the Borrower will offer an amendment to this Agreement concerning the compliance with financial covenants by which the Bank would be in the same position as the other creditors concerning the compliance with financial covenants. [The Borrower confirms to the Bank that prior to the date of this Agreement it has not agreed on the compliance with financial covenants with other creditors.

If a deadline for remedial action has not been set or if the set deadline has unsuccessfully expired, the Bank shall be initially entitled to require the Borrower to provide or increase bankable securities to secure the claims of the Bank under this Agreement.
