4. Certain Covenants of Stockholder.

7. Representations and Warranties of Buyer. Buyer hereby represents and warrants to each Stockholder as follows:

7.1 Due Authority. Buyer is an entity duly organized, validly existing and in good standing under the Laws of its jurisdiction of formation. Buyer has all requisite organizational power and authority and has taken all organizational action necessary (including approval by its board of directors or applicable organizational bodies) to execute, deliver and perform its obligations under this Agreement in accordance with the terms hereof and no other organizational action by Buyer or vote of holders of any class of the capital stock of Buyer is necessary to authorize the execution and delivery of, compliance with and performance by Buyer of, this Agreement. This Agreement has been duly executed and delivered by Buyer and, assuming the due execution and delivery of this Agreement by each Stockholder, constitutes a valid and binding agreement of Buyer enforceable against Buyer in accordance with its terms, subject to the Enforceability Exceptions.

7.2 Stockholders Agreements. Buyer agrees to use reasonable endeavors to enter into a tender support agreement with KfW under which KfW agrees to:

(a) waive its right of first refusal set forth in the KfW-dievini SHA and agree and consent to any disposal of Company Shares tendered by each Stockholder in the Offer and to terminate the KfW-dievini SHA effective as of the Closing Date, subject to each Stockholder (i) waiving its right of first refusal set forth in the KfW-dievini SHA, (ii) agreeing and consenting to any disposal of Company Shares tendered by KfW in the Offer and (iii) agreeing to terminate the KfW-dievini SHA effective as of the Closing Date; and

(b) terminate the Relationship Agreement effective as of the Closing Date, subject to the termination of the KfW-dievini SHA.

7.3 Most Favoured Nation. The terms and conditions of this Agreement, taken as a whole, are no less favorable in any material respect to Stockholder than the terms and conditions of any other tender and support agreement or similar agreement entered into by Buyer with any other shareholder of the Company in connection with the Transactions (each, an “Other Tender and Support Agreement”); provided, that the foregoing provisions shall not apply (i) with respect to any tender and support agreement or similar agreement entered into between Buyer, on the one hand, and any member of the management board (bestuur) or the supervisory board (raad van commissarissen) of the Company, on the other hand, or (ii) with respect to the subject matter of Section 4.4 of this Agreement in connection with any tender and support agreement or similar agreement entered into between Buyer, on the one hand, and Kreditanstalt für Wiederaufbau, on the other hand (each of (i) and (ii), an “Excluded Other Tender and Support Agreements”) except for the provisions relating to the amount and the kind of Offer Consideration contained in such Excluded Other Tender and Support Agreements, and the Excluded Other Tender and Support Agreements shall except for the provisions relating to the amount and the kind of Offer Consideration contained in such Excluded Other Tender and Support Agreements not be included in the definition of “Other Tender and Support Agreements” for purposes of this Section 7.3. In the event that Buyer enters into, amends, or modifies any Other Tender and Support Agreement after the date hereof, and such Other Tender and Support Agreement contains terms or conditions that are, taken as a whole, more favorable to such other shareholder than the terms and conditions provided to Stockholder under this Agreement, Buyer shall promptly notify Stockholder in writing of such more favorable terms or conditions, and this Agreement shall be deemed automatically amended, without any further action by the parties, to incorporate such more favorable terms or conditions as of the date such Other Tender and Support Agreement is entered into, amended, or modified, as applicable. For the avoidance of doubt, this Section shall not apply to any terms or conditions that reflect differences in the number or type of securities held by any shareholder.

7.4 No Conflict. The execution, delivery and performance by Buyer of this Agreement do not and will not, other than as provided in the Purchase Agreement with respect to the Offer, the Post-Offer Reorganization and the other Transactions, (a) conflict with or result in any violation or breach of any provision of the certificate of incorporation or bylaws or similar organizational documents of Buyer, (b) conflict with or result in a violation or breach of any applicable Law, (c) require any consent by any Person under, constitute a default, or an event that, with or without notice or lapse of time or both, would constitute a default under, or cause or permit the termination, cancellation or acceleration of any right or obligation or the loss of any benefit to which Buyer is entitled, under any Contract binding upon Buyer, or to which any of its properties, rights or other assets are subject or (d) result in the creation of any Lien (other than a Permitted Lien) on any of the properties or assets (including intangible assets) of Buyer, except in the case of clauses (b), (c) and (d), for any such violation, breach, conflict, default, termination, acceleration, cancellation or loss that would not reasonably be expected to restrict, prohibit or impair the performance by Buyer of its obligations under this Agreement.

8. Non-Survival of Representations, Warranties and Covenants. Except as provided in Section 3, the representations, warranties and covenants contained herein shall not survive the Termination Date.

9. Waiver of Appraisal and Dissenter Rights and Certain Other Actions.

9.1 Each Stockholder hereby irrevocably and unconditionally waives, to the extent of the Law, and agrees to cause to be waived and not to assert (a) any appraisal rights, any dissenter’s rights, any rights of first refusal, any tag-along rights, any drag-along rights and any other rights under any existing shareholders agreement and applicable Law with respect to any of the Company Shares in connection with the Offer, the Post-Offer Reorganization, and the other Transactions, and (b) any rights to object to or challenge the consummation of the Offer, the Post-Offer Reorganization or any of the other Transactions.

9.2 Each Stockholder hereby agrees (a) not to commence or affirmatively participate in or receive any economic or other benefit from any claim or other Action, whether derivative or otherwise, against Buyer, the Company or any of their respective Affiliates or successors, or their respective boards of directors (or similar governing bodies), relating to the negotiation, execution or delivery of this Agreement or the consummation of the Transactions or the transactions contemplated hereby or the consummation of the Offer, the Post-Offer Reorganization or the other Transactions, including any such claim or other Action (i) challenging the validity of, or seeking to enjoin the operation of, any provision of this Agreement or the Purchase Agreement, the Post-Offer Reorganization or the other Transactions (ii) alleging a breach of any fiduciary duty of the Company Boards in connection with the Purchase Agreement the Post-Offer Reorganization or the other Transactions, or (iii) with respect to SEC disclosure or other disclosure to the Company Stockholders in connection with this Agreement, the Purchase Agreement, the Post-Offer Reorganization or the other Transactions or the transactions contemplated hereby, and (b) to take all actions necessary to opt out of any class in any class action relating to any of the foregoing; provided, that the foregoing shall not limit, restrict or prohibit such Stockholder from claiming or asserting any defenses or counterclaims in connection with any Action arising out of or in connection with the Purchase Agreement, the Post-Offer Reorganization, this Agreement or the other Transactions.

10. Certain Adjustments; Additional Owned Shares. In the event of a stock split, stock dividend or distribution, or any change in the Company Shares by reason of any split-up, reverse stock split, recapitalization, combination, reclassification, exchange of shares or the like, the terms “Company Shares,” “Covered Shares,” “Disclosed Owned Securities,” “Owned Shares,” “Additional Owned Shares” and similar terms shall be deemed to refer to and include such shares as well as all such stock dividends and distributions and any securities into which or for which any or all of such shares may be changed or exchanged or which are received in such transaction. In the event that Stockholder acquires record or beneficial ownership of, or the power to vote or direct the voting of, any Additional Owned Shares, such Additional Owned Shares shall, without further action of the parties, be subject to the provisions of this Agreement, the representations and warranties of Stockholder in Section 5 shall be true and correct as of the date that beneficial ownership of Additional Owned Shares is acquired, and the number of Owned Shares set forth on Exhibit A opposite the name of such Stockholder will be deemed amended accordingly. Stockholder shall promptly notify Buyer in writing of any such event and of the number of Additional Owned Shares acquired.

11. Reliance. Stockholder understands and acknowledges that Buyer is entering into the Purchase Agreement in reliance upon Stockholder’s execution, delivery and performance of this Agreement.

15. Entire Agreement; Counterparts; Electronic Delivery. This Agreement, including the Exhibits hereto, and the other documents delivered in connection with this Agreement, constitutes the entire agreement, and supersedes all prior agreements and understandings, both written and oral, among the parties with respect to the transactions contemplated herein. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Any such counterpart, to the extent delivered by fax or .pdf, .tif, .gif, .jpg or similar attachment to email (any such delivery, an “Electronic Delivery”), shall be treated in all manner and respects as an original executed counterpart and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No party may raise the use of an Electronic Delivery to deliver a signature, or the fact that any signature or agreement or instrument was transmitted or communicated through the use of Electronic Delivery, as a defense to the formation of a Contract, and each party hereby forever waives any such defense, except to the extent that such defense relates to lack of authenticity. This Agreement shall become effective when each party shall have received a counterpart of this Agreement signed by each other party. Until and unless each party has received a counterpart of this Agreement signed by each other party, this Agreement shall have no effect and no party shall have any right or obligation hereunder (whether by virtue of any other oral or written agreement or other communication).

16. Governing Law. This Agreement, and any Action arising out of or relating to this Agreement or the transactions contemplated hereby, shall be governed by, and construed in accordance with, the Laws of the State of Delaware, without regard to choice or conflict of Law principles thereof; provided, that, notwithstanding the foregoing, any matters concerning or implicating the Company Boards’ fiduciary duties shall be governed by and construed in accordance with the applicable fiduciary duty Laws of The Netherlands.

17. Dispute Resolution. Any dispute, controversy, or claim arising out of or relating to this Agreement (and any subsequent amendments thereof), or the breach, termination, or validity thereof or the transactions contemplated hereby (each a “Dispute”) shall be resolved in accordance with this Section 17.

(a) Consent to Jurisdiction. For purposes of resolving any Dispute, each party (a) irrevocably and unconditionally submits to the personal jurisdiction of the Court of Chancery of the State of Delaware (or, only if such court declines to accept jurisdiction over a particular matter, then in the United States District Court for the District of Delaware, or if jurisdiction is not then available in the United States District Court for the District of Delaware (but only in such event), then in any Delaware state court sitting in New Castle County) (the “Chosen Court”), (b) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such Chosen Court, (c) waives any claim of improper venue or any claim that the Chosen Court is an inconvenient forum, and (d) agrees that, subject to Section 17(b) below, it shall not bring any action relating to a Dispute in any forum other than the Chosen Court. Each of the parties hereby irrevocably and unconditionally waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in any action or proceeding arising out of or relating to a Dispute: (i) any claim that such party is not personally subject to the jurisdiction of the Chosen Court as described herein for any reason; (ii) that it or its property is exempt or immune from jurisdiction of any such Chosen Court or from any legal process commenced in such courts (whether through service of process, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise); and (iii) that (A) the action in any such court is brought in an inconvenient forum, (B) the venue of such action is improper or (C) this Agreement, or the subject matter hereof, may not be enforced in or by such Chosen Court.

(b) Arbitration. In the event that a Chosen Court of first instance declines jurisdiction over an action brought in accordance with Section 17(a), the associated Dispute shall be resolved by final and binding arbitration administered by the International Chamber of Commerce (the “ICC”) in accordance with its Rules of Arbitration in effect at the time (the “Rules”), except as modified herein.

(i) The seat of arbitration shall be Frankfurt, Germany and the arbitration shall be conducted in the English language.

(ii) The arbitration shall be conducted by three arbitrators. The claimant and respondent shall each nominate one arbitrator within thirty (30) days of receipt by respondent of the demand for arbitration. The two arbitrators so nominated shall nominate the third and presiding arbitrator (the “Presiding Arbitrator”) within thirty (30) days of the confirmation by the ICC Court of Arbitration (“ICC Court”) of the second arbitrator. If any party fails to nominate an arbitrator, or if the two party-nominated arbitrators fail to nominate the Presiding Arbitrator, within the time periods specified herein, then any such arbitrator shall, upon any party's request, be appointed by the ICC Court in accordance with the Rules.

(iii) By agreeing to arbitration, the parties do not intend to deprive any court of its jurisdiction to issue an injunction, attachment or other order in aid of arbitration proceedings. Without prejudice to such provisional remedies that may be granted by a court, the arbitrators shall have full authority to grant provisional remedies, to order a party to request that a court modify or vacate any temporary or preliminary relief issued by such court, and to award damages for the failure of any party to respect the arbitrators’ orders to that effect.

(iv) The award of the arbitrators shall be final and binding upon the parties thereto, and shall be the sole and exclusive remedy between the parties regarding any Dispute presented to the arbitrators. Judgment upon any award may be entered in any court having jurisdiction over any party or any of its assets.

(c) The parties agree that irreparable damage, for which monetary damages, even if available, would not be an adequate remedy, will occur in the event that the parties do not perform their obligations under the provisions of this Agreement in accordance with its specified terms or otherwise breach such provisions. Subject to the following sentence, the parties acknowledge and agree that (a) the parties shall be entitled to seek an injunction or injunctions, specific performance or other equitable relief to prevent breaches or threatened breaches of this Agreement and to enforce specifically the terms and provisions hereof in the Chosen Courts without proof of damages or otherwise, this being in addition to any other remedy to which they are entitled under this Agreement and (b) the right of specific performance is an integral part of the transactions contemplated herein and without that right, none of the parties would have entered into this Agreement. The parties acknowledge and agree that any party seeking an injunction or injunctions to prevent breaches or threatened breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this Section 17(c) shall not be required to provide any bond or other security in connection with any such Order or injunction.

(d) Waiver of jury trial. Each party acknowledges and agrees that any controversy that may arise under this Agreement is likely to involve complicated and difficult issues and, therefore, each such party irrevocably and unconditionally waives any right it may have to a trial by jury in respect of any Action (whether based on contract, tort or otherwise) directly or indirectly arising out of or relating to this Agreement, the other documents and agreements delivered in connection herewith or the transactions contemplated hereby or thereby or the actions of the parties in the negotiation, administration, performance and enforcement hereof or thereof. Each party certifies and acknowledges that (a) no Representative of any other party has represented, expressly or otherwise, that such other party would not seek to enforce the foregoing waiver in the event of an Action, (b) such party has considered and understands the implications of this waiver, (c) such party makes this waiver voluntarily and (d) such party has been induced to enter into this Agreement by, among other things, the mutual waivers and certifications in this Section 17(d).

18. Assignability. This Agreement shall be binding upon, and shall be enforceable by and inure solely to the benefit of, the parties hereto and their respective successors and permitted assigns; provided, however, that neither this Agreement nor any of the rights hereunder may be assigned by a party hereto without the express written consent of the other parties, and any attempted assignment of this Agreement or any of such rights without such consent shall be null and void, except that (a) Buyer may transfer or assign its rights and obligations under this Agreement to any Affiliate of Buyer without the written consent of Stockholder, and (b) after the Acceptance Time, Buyer may transfer or assign its rights and obligations under this Agreement to any Person, provided that in each case Buyer shall remain jointly and severally liable with such assignee for any and all obligations of Buyer under this Agreement and the Purchase Agreement.

19. No Third Party Beneficiaries. This Agreement is not intended to, and shall not, confer upon any Person other than the parties any rights or remedies.

20. Rules of Construction. The parties have participated jointly in negotiating and drafting this Agreement. If an ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.

21. No Ownership Interest. Stockholder has agreed to enter into this Agreement and act in the manner specified in this Agreement for consideration. Except as expressly set forth in this Agreement, nothing contained in this Agreement shall be deemed, upon execution, to vest in Buyer any direct or indirect ownership or incidence of ownership of or with respect to any Covered Shares. All rights, ownership and economic benefits of and relating to the Covered Shares shall remain vested in and belong to Stockholder, and Buyer shall not have any authority to manage, direct, superintend, restrict, regulate, govern or administer any of the policies or operations of the Company or exercise any power or authority to direct Stockholder in the voting of any of the Covered Shares, except as otherwise provided in this Agreement. Nothing in this Agreement shall be interpreted as creating or forming a “group” with any other Person, including Buyer, for purposes of Rule 13d-5(b)(1) of the 1934 Act or any other similar provision of applicable Law or of conferring upon Buyer beneficial ownership of any Covered Shares at any time prior to the Acceptance Time.

22. Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other Governmental Authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated, so long as the economic or legal substance of the transactions contemplated herein is not affected in any material way. Upon such a determination, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated herein be consummated as originally contemplated to the extent possible.

23. Amendment; Waiver. This Agreement may only be amended or supplemented at any time by additional written agreements signed by, or on behalf of, the parties, as may mutually be determined by the parties to be necessary, desirable or expedient to further the purpose of this Agreement or to clarify the intention of the parties. No provision of this Agreement may be waived or extended except by a written instrument signed by the party against whom the waiver or extension is to be effective. No failure or delay on the part of any party in the exercise of any right hereunder shall impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty or agreement in this Agreement, nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or of any other right.

24. Spousal Consent. If Stockholder is married and any of the Covered Shares may constitute community property or otherwise need spousal or other approval for this Agreement to be legal, valid and binding, such Stockholder shall deliver to Buyer, concurrently herewith, a duly executed consent of such Stockholder’s spouse, in the form attached hereto as Exhibit C.

25. Directors and Officers. Notwithstanding any provision of this Agreement to the contrary, nothing in this Agreement shall limit or restrict Stockholder, or a designee of Stockholder, who is a director or officer of the Company from acting in such capacity or fulfilling the obligations of such office, including by voting, in his or her capacity as a director of the Company, in Stockholder’s, or its designee’s, sole discretion on any matter (it being understood that this Agreement shall apply to Stockholder solely in such Stockholder’s capacity as a stockholder of the Company). In this regard, Stockholder shall not be deemed to make any agreement or understanding in this Agreement in Stockholder’s capacity as a director or officer of the Company.
