E.

As a result of the Transfer, as at today’s date, Tekne’s share capital, amounting to Euro 1,111,414.00, represented by 1,111,414 ordinary shares with a nominal value of Euro 1.00 (one/00) (the “Shares”), is held as follows (the “Tekne Shareholdings”):

In the letter of intent, the Parties therefore agreed the terms and conditions of a transaction (the “Transaction”) concerning, inter alia:

(i)

(iii)

the completion of a plan to restructure the Company’s financial exposure through the signing of agreements in support of the Certified Restructuring Plan with the relevant creditors and the completion of all activities and transactions related thereto.

K.

Subject to the terms and conditions set out in this Agreement, the Parties intend to govern the terms and conditions of the Investment, as well as any further agreements relating to the Certified Restructuring Plan, acknowledging that the execution of this Agreement aims to provide stability to the Company and enable the latter to implement the Certified Restructuring Plan, consistent with the timing and cash flow requirements that the emergence from the crisis, the restructuring of the Company and/or the assessment of a possible State Intervention may entail.

the significantly detrimental effect of such requirements and/or recommendations (if accepted) solely on the Company’s prospective valuation compared with the Company Valuation (calculated using the same methodologies); or

(iv)

if no agreement is reached within the time limit referred to in paragraph 9.1.3(iii) above, the Condition Precedent shall not be deemed to have been fulfilled.

10.1.4

The Parties’ obligation to act in good faith while the Condition Precedent is pending remains unaffected, including for the purposes of Article 1358 of the Civil Code.
