(A)CFIUS Notice. Each of the Borrower and Lender shall (and shall cause their respective Affiliates to) (i) prepare and submit to CFIUS, as soon as practicable, and in any case within thirty (30) business days of the date of this First Amendment, a draft CFIUS Notice, (ii) submit a formal CFIUS Notice pursuant to the DPA as soon as practicable or, if applicable, after receipt of any comments to the draft CFIUS Notice, and (iii) provide any supplemental information and other related information requested by CFIUS pursuant to the DPA as soon as practicable (and, in any case, within the time periods required by

Each of the Borrower and Lender shall, in connection with the efforts to obtain CFIUS Clearance, (i) cooperate in all respects and consult with each other in connection with the CFIUS Notice, including by allowing each other to have a reasonable opportunity to review in advance and comment on drafts of filings and submissions, (ii) to the extent not prohibited by CFIUS, promptly inform each other of any communication received by any party from, or given by any party to, CFIUS, including by promptly providing copies to each other of any such written communications, (iii) permit each other to review in advance any substantive communication that is given to, and consult with each other in advance of any conference, meeting, or substantive telephone call with, CFIUS, and to the extent not prohibited by CFIUS, provide each other the opportunity to attend and participate in any conference, meeting, or substantive telephone call with CFIUS and (iii) enter into such commercially reasonable assurances or agreements requested or required by CFIUS or the President of the United States to obtain CFIUS Clearance; provided, however, that neither Lender nor any of its Affiliates shall be required to (w) take any action that would violate any Law applicable to Lender or any of its Affiliates, (x) sell, divest, or dispose of any assets or businesses that Lender or any of its Affiliates hold, (y) provide the Borrower with copies of or permit the Borrower to review or receive the “personal identifier information” required under 31 C.F.R. § 800.502(c)(5)(vi), or (z) otherwise adopt conditions or restrictions that would reasonably be expected to have, individually or in the aggregate, an adverse effect on the value of the Lender’s investment. For purposes of this Section 3.07 “commercially reasonable efforts” shall not be construed to require any party to enter into litigation to overturn or challenge any governmental determination or action with respect to the DPA.

(C)Lender Consent. The Borrower shall not, and shall cause their respective Affiliates not to, take or agree to take any action, condition or restriction required by CFIUS in connection with obtaining CFIUS Clearance except with the advance written consent of Lender.

(e)Section 6(a)(i) of the Loan Agreement is hereby amended in its entirety as follows:

Generally. Following receipt of CFIUS Clearance and the subsequent conversion of the Loan, and for so long as Lender and its Permitted Transferees continue to have record and beneficial ownership (within the meaning of Rule 13d-3 under the Exchange Act) of at least 10% of the outstanding Common Shares of the Borrower (in each case, the “Nomination Right Condition”), Lender and its Permitted Transferees, if any, shall have the right to designate two persons for appointment to the Supervisory Board of Directors (an “Lender Nominee”), at each annual general meeting of shareholders of the Borrower in which one or more members of the Supervisory Board of Directors are up for appointment or re-appointment. If Lender and its Permitted Transferees, if any, have the right to so designate one or two Lender Nominees in a given year, the Supervisory Board

3

of Directors shall upon each such designation having been made nominate each Lender Nominee so designated for appointment or re-appointment, as applicable, by the general meeting of shareholders of the Borrower to the Supervisory Board of Directors in accordance with the Articles of Association and Dutch law. If, following appointment or re-appointment to the Supervisory Board of Directors, a Lender Nominee resigns, is removed, is not re-appointed or is otherwise unable to serve for any reason and Lender and its Permitted Transferees, if any, still have the right to designate a Lender Nominee, then Lender and its Permitted Transferees, if any, shall be entitled to designate a replacement Xxxxxx Xxxxxxx, and the Supervisory Board of Directors shall upon such designation nominate the Lender Nominee for appointment by the general meeting of shareholders to the Supervisory Board of Directors in accordance with the Articles of Association and Dutch law. In the event that Lender and its Permitted Transferees, if any, cease to satisfy either Nomination Right Condition, if requested by the Supervisory Board of Directors, Lender and its Permitted Transferees, if any, shall use reasonable efforts to have such Xxxxxx Nominee resign as a member of the Supervisory Board of Directors.

(f)A new Section 6(h) of the Loan Agreement is hereby added as follows:

Control Rights Upon Conversion. Following receipt of CFIUS Clearance and the subsequent conversion of the Loan, and for so long as the Nomination Right Condition is met, the Lender’s prior written consent (which shall not be unreasonably withheld, conditioned or delayed) shall be required in order for the Borrower to select a new line of business or venture.

SECTION 3.Effectiveness.  This Amendment shall become effective upon the execution and delivery of this Amendment by the Borrower and the Lender.

SECTION 4.Miscellaneous.

(a)Compliance.  The Borrower agrees to comply with the applicable terms, provisions, and conditions of the Loan Agreement, after giving effect to the terms of this Amendment, notwithstanding any prior conduct of the Lender or any course of dealing among the Lender and the Borrower prior to the date hereof to the contrary.

(b)Transaction Document.  For avoidance of doubt, each of the parties hereto hereby acknowledges and agrees that this Amendment is a “Transaction Document” (as defined in the Loan Agreement).

(c)Representations and Warranties.  To induce the Lender to enter into this Amendment, the Borrower hereby confirms that (i) all of the representations and warranties set forth in the Loan Agreement are true and correct in all material respects (without duplication of any materiality qualifier in the text of such representation or warranty) as of the date hereof except to the extent that any such representation or warranty relates to a specific date in which case such representation or warranty shall be true and correct as of such earlier date and (ii) no Default or Event of Default has occurred and is continuing as of the date hereof. The Borrower acknowledges and agrees that the Loan Agreement, the other Transaction Documents and this Amendment constitute the legal, valid and binding obligation of the Borrower, and are enforceable against the

4

Borrower in accordance with its terms, except as the enforceability thereof may be limited by bankruptcy, insolvency or other similar laws relating to the enforcement of creditors’ rights generally and by general equitable principles.

(d)Effect of Agreement; No Waiver or Novation.  Except as set forth expressly hereinabove, all terms of the Loan Agreement and the other Transaction Documents shall be and remain in full force and effect, and shall constitute the legal, valid, binding, and enforceable obligations of the Borrower and the Lender, as applicable. The execution, delivery and effectiveness of this Amendment shall not, except as expressly provided in this Amendment, operate as a waiver of any right, power or remedy of the Lender, nor constitute a waiver of any provision of the Loan Agreement or any other Transaction Document. Nothing herein is intended or shall be construed as a waiver of any existing Defaults or Events of Default under the Loan Agreement or the other Transaction Documents or any of the Lender’s rights and remedies in respect of any Defaults or Events of Default. This Amendment is not intended to be, nor shall it be construed as, a novation of the Loan Agreement.

(e)Counterparts.  This Amendment may be executed in any number of counterparts and by different parties hereto in separate counterparts (including via pdf, facsimile or other method of electronic transmission), each of which when so executed and delivered shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same instrument. This Amendment may be executed by each party on separate copies, which copies, when combined so as to include the signatures of all parties, shall constitute a single counterpart of the Agreement.

(f)Further Assurances.  Each party hereto agrees to take, at its expense, such further actions as the other party shall reasonably request from time to time to evidence the agreements set forth herein and the transactions contemplated hereby.

(g)Governing Law.  This Amendment shall be governed by and construed and interpreted in accordance with the internal laws of the State of New York. Sections 10(e), (f) and (g) of the Loan Agreement and Sections 8.03, 8.04 and 8.10 of the Terms and Conditions are hereby incorporated herein by reference mutatis mutandis.

(h)Severability.  Any provision of this Amendment which is prohibited or unenforceable shall be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof in that jurisdiction or affecting the validity or enforceability of such provision in any other jurisdiction.

(i)Release.  In consideration of the agreements of the Lender contained herein and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Borrower, voluntarily, knowingly, unconditionally and irrevocably, with specific and express intent, for and on behalf of itself and all of its respective parents, subsidiaries, affiliates, members, managers, predecessors, successors, and assigns, and each of its respective current and former directors, officers, shareholders, agents, and employees, and each of its respective predecessors, successors, heirs, and assigns (individually and collectively, the “Releasing Parties”) does hereby fully and completely release, acquit and forever discharge of the Lender, and each its parents, subsidiaries, affiliates, members, managers, shareholders, directors,
