CANCELLATION NOTICE FOR THE ANNUAL GENERAL MEETING OF SHAREHOLDERS AND THE EXTRAORDINARY GENERAL MEETING OF SHAREHOLDERS

Notice is hereby given to the holders of shares of European CleanTech I SE (the 'Company') that the management board of the Company with the approval of the supervisory board has resolved to cancel:

the ANNUAL GENERAL MEETING OF SHAREHOLDERS (the 'AGM'),

initially scheduled to be held on June 15, 2012 at 11:00 Central European Summer Time ('CEST') at Hotel Le Royal, 12 boulevard Royal, L-2449 Luxembourg in Luxembourg and to reconvene such meeting at a later date by separate convening notice, and

the EXTRAORDINARY GENERAL MEETING OF SHAREHOLDERS (the 'EGM'),

initially scheduled to be held on June 15, 2012 at 11:30 CEST at Hotel Le Royal, 12 boulevard Royal, L-2449 Luxembourg in Luxembourg and to reconvene such meeting at a later date by separate convening notice.

The management board and the supervisory board of the Company believe that cancelling the initially scheduled EGM and rescheduling it at a later date will allow the shareholders of the Company (including shareholders who have indicated an intention to seek redemption of their Class A Shares) to have additional time to consider and evaluate the proposals described in the original convening notice for the AGM and the EGM and the related proxy statement.

Proxy, voting and registration forms published and made available in connection with the AGM and the EGM and redemption notices and withdrawal notices published and made available in connection with the EGM are no longer valid and should no longer be used. Any certificate as to the number of Class A Shares ('Public Shares') held on June 1, 2012, proxy, voting or registration form received in connection with the AGM and the EGM, and any redemption notices and withdrawal notices received in connection with the EGM will be deemed void and will have no effect.

As a consequence, Public Shares previously tendered for redemption in connection with the EGM will be returned to shareholders as soon as possible and will not be redeemed. Public Shares for which redemption notices have been withdrawn will also be returned to shareholders as soon as possible.

Documentation related to the reconvened AGM and EGM, including new proxy, voting and registration forms, redemption notices and withdrawal notices will be published together with the separate convening notice for the reconvened AGM and EGM. Holders of Public Shares will have the opportunity to tender their Public Shares for redemption in connection with the reconvened EGM in accordance with the articles of association of the Company as will be described in the separate convening notice for the reconvened AGM and EGM.

For the management board of the Company.

Pursuant to Article 4 of the Luxembourg Shareholders' Rights Law and the Company's articles of association, such request and draft resolution(s) must be received at the Company's registered office by registered letter or by e-mail at least twenty-two (22) days prior to the date of the relevant general meeting of shareholders, i.e., prior to June 29, 2012, accompanied by a proof of the shareholding of such shareholder(s) and the address or e-mail address which the Company may use in order to deliver the acknowledgment of receipt of such request.

For the avoidance of doubt, the fourteen (14) days' period does prevail at all times over the five (5) days' period.
