ARTICLE 4 - AMENDMENT TO ARTICLE 8 - CLAW-BACK MECHANISM

Article 8.1 of the Contract “Claw-back mechanism” is deleted and replaced by the following:

The claw-back mechanism shall be implemented on the basis of ex-post calculations, which have been approved annually by the auditors of the Beneficiary and any Authorised Entity.

To this end, the Beneficiary undertakes to keep (and procures that any Authorised Entity shall keep), separate cost accounting records for the entire duration of the Contract, so that financial flows relating to the Programme to be reconstituted and the amount to be clawed-back calculated in accordance with the method described in Appendix 3 - (Accounting Methodology).

In addition, each year from the start of the Programme, the Beneficiary provides Bpifrance with a summary statement of cash flows to update the Funding Gap Questionnaire based on the data from the previous year. Such data is communicated in the Monitoring Reports. After the end of the Programme, the data is communicated no later than 30 April of each year following the end date of the Programme until the Contract expires.

From the claw-back start date, i.e. 30 June of the first year following the Programme End Date (the “First Test”), and no later than the claw-back end date, i.e. 30 September 2040 (30/09/2040) (the “Last Test”, together with the First Test, the “Test(s)”), a test is carried out (the First Test and the Last Test being hereinafter referred to as a “Test”) in order to determine the surplus amount (hereinafter referred to as the “Surplus”) for the year in question. The “Last Test” is carried out taking into account the period elapsed from 14 March 2023 until the end of the claw-back period.

The claw-back start date is: 30 June 2033 (30/06/2033).

The claw-back end date is the Programme end dated plus 8 years, i.e.: 30 September 2040 (30/09/2040).

In the event that the Programme is delayed, the claw back end date will take into account the effective end date of the Programme and will be changed by means of an amendment.

The calculation of the Surplus involves following data:

Notified WACC means the weighted average cost of capital (referred to in the Decision as the “WACC”) applicable to the Programme and notified to the European Commission for the purposes of the Decision: [***]%.

 

 

7


NPV refers to the discounted net present value for year “i” in question, using the Notified WACC as the discount coefficient.

For example: for a Test in 2033, 2023 cash flow will be multiplied by (1 + Notified WACC) raised to the power of 10.

Starting as from the First Test and then at the Last Test, the Surplus is calculated as the sum (positive or negative) of the amounts of:

a. the NPV of the actual audited ex post cash flows after tax including capital expenditure (“CAPEX”) and the payment of additional public aid, in particular the Research Tax Credit, excluding payments of the Aid and financing cash flows, from 14 March 2023 up to the year of the Test in question; and

b. the NPV of the actual Aid payments from 14 March 2023 up to the year of the Test in question.

The Surplus, if positive, is multiplied by an allocation ratio (hereinafter referred to as the “Allocation Ratio”), equal to the lesser between:

 

 

 

[***]%; or

 

 

 

the net payment of the Aid from 14 March 2023, up to the year of the Test in question, divided by Eligible Expenses for the Programme monitored from 14 March 2023 up to the year of the Test in question (amounts expressed in nominal terms).

For each Test, Bpifrance determines, in accordance with the terms of the Decision, the amount of the claw-back on the date of the Test and, where relevant, the share due to Bpifrance, and communicates it to the Beneficiary.

This claw-back mechanism applies only in the event of a positive net present value of cash flows after taking account of actual Aid payments. No surplus can be generated if the Programme has a negative net present value after Aid payments.

ARTICLE 5 – AMENDMENTS TO THE APPENDICES

The Appendices “APPENDIX 1 – FINANCIAL APPENDICE” and “APPENDIX 1 BIS – FINANCIAL APPENDIX” are deleted and replaced by the Appendix 1BIS attached hereto.

ARTICLE 6 – FINAL PROVISION

This Amendment Agreement shall enter into force upon its signature.
