6

4.4 Other restrictions on redemption

4.4.1 Before the Mandatory Redemption Date, no Holder shall have any right, power, privilege or ability to demand, sue for or otherwise make claims in respect of the acceleration, conversion, redemption or repurchase of the PECs or any portion thereof other than in connection with a Liquidation pursuant to section 4.3.1 or by application of section 8.2.

5 LIMITED RECOURSE

5.1 The PECs are direct, unsecured and limited recourse obligations of the Company. The Company’s ability to satisfy its payment obligations under the PECs (i.e. repayment of the Par Value of the PECs and payment of Yield) will be wholly dependent on the amount of payments the Company receives from the receivable owed under the preferred equity certificates issued by Kinove Luxembourg Holdings 3 S.à r.l in the initial amount of EUR 277,450,000 due by 28 July 2011 (e.g. repayment of principal and payment of any income) over all Accrual Periods, reduced by EUR 2 million of the Par Value of the PECs (the “Full-Recourse Amount”) which will be due by the Company even if no repayment of principal or payment of interest is made under the receivable owed under the preferred equity certificates issued by Kinove Luxembourg Holdings 3 S.à r.l. described above.

5.2 Other than the foregoing, the Company will have no other funds available to meet its obligations under the PECs and the PECs will not give rise to any payment obligation in excess of the foregoing.

5.3 Except for the Full-Recourse Amount, recourse to the Company shall be limited to the receivable owed under the preferred equity certificates issued by Kinove Luxembourg Holdings 3 S.à r.l. and the proceeds thereof. If those are ultimately insufficient, then the Holder shall have no further recourse or claim against the Company or any other person for any shortfall arising or any loss sustained and the claim shall be extinguished and the then outstanding PECs shall lapse.

6. WITHHOLDING TAXES

All payments on the PECs shall be made free and clear of withholding taxes imposed by any taxing jurisdiction, unless the withholding of such tax is required by law.

7. COVENANTS

As long as any PEC is outstanding, the Company will not issue any shares of capital having, upon or following any Liquidation, any right to payment prior to the payment in full of the Par Value for each outstanding PEC plus all accrued and unpaid Yield to the Holder of each PEC. The Company shall not take its liquid assets or funds to pay dividends on Shares or any return on share premium, if any, as long as due and unpaid Yield on all then outstanding PECs have not been previously settled. The redemption of existing Shares of capital stock by way of decrease of capital or the repayment of share premium, if any, duly decided in a Shareholders’ meeting, in conformity with the law shall not take place whilst PECs are outstanding, unless PECs are redeemed at the same occasion in such a manner that the PEC Ratio remains the same as prior to said redemption.

7

8. DEFAULT

8.1 Each of the following events shall constitute an “Event of Default”:

(i) the Company shall fail to pay the full amount of any declared Yield on the applicable Payment Date or make any payments required under section 4 and such failure continues for (3) three Business Days following such Payment Date; or

(ii) the Company shall fail to comply with the provisions of section 7; or

(iii) except as expressly permitted herein, the Company shall

a. be dissolved or liquidated, or

b. become Insolvent or unable to pay its debts as they become due, or

c. institute or have instituted against it a proceeding seeking a judgement of insolvency or bankruptcy or any other relief under bankruptcy or insolvency law or other similar law affecting creditors’ rights, and in the case any such proceeding or petition instituted or presented against it, such proceeding or petition (x) results in a judgement of insolvency or bankruptcy or the entry of an order for relief or the making of an order for its winding-up or liquidation of (y) is not dismissed, discharged, stayed or restrained in each case within 90 days of the institution or presentation thereof.

8.2 If an Event of Default has occurred and is continuing for more than 30 Business Days, the provisions of section 4.1 shall apply as if the Mandatory Redemption Date had occurred.

9. REGISTRATION OF THE PECS; TRANSFER RESTRICTIONS

9.1 The name and address of the Holder of each PEC shall be entered into the PEC Register by the Company. Except as expressly required by law, the Person in whose name the PECs are registered in the PEC Register shall be deemed to be the owner and record holder thereof for all purposes.

9.2 Each PEC may be transferred or pledged only simultaneously with and to the same Person as Shares held by the same transferor, and any such transfer or pledge of Shares and PECs must be made in a combination that reflects the proportion of PECs and Shares held by the relevant tranferor immediately prior to the transfer or pledge. Upon a transfer or pledge of Shares by a Holder of PECs, such Holder shall transfer or pledge its PECs simultaneously with and to the same Person to whom such Holder’s Shares are being transferred or pledged, and any such transfer or pledge of Shares and PECs must be made in a combination that reflects the proportion of PECs and Shares held by the relevant tranferor immediately prior to the transfer or pledge.

8

9.3 PECs shall not be transferred except in compliance with the terms of the Shareholders’ Agreement and the articles of association of the Company. Any purported transfer of a PEC in violation of the Shareholders’ Agreement or the articles of association of the Company shall be null and void.

10.3 If any time period for giving notice or taking action hereunder expires on a day which is not a Business Day, the time period shall automatically be extended to the Business Day immediately following such Saturday, Sunday or legal holiday.

10.4 These Terms and Conditions constitute the entire agreement between the Company and the Holders with respect to the subject matter hereto and supersedes any prior understandings, agreements, or representations by or among the Company and the Holders, written or oral, that may have related in any way to the subject matter hereof.

11. GENERAL TERMS AND CONDITIONS OF PECS

11.1 Subject to the terms and conditions hereof, the PECs shall, with respect to payment rights, redemption and rights of liquidation, winding up and dissolution, rank pari passu amongst themselves and with any other convertible or non convertible, yield bearing or yield free, preferred equity certificates issued by the Company from time to time, and rank prior to all Subordinated Securities but shall be subordinated to all other present and future obligations of the Company whether secured or unsecured.

11.2 The PECs may be issued in whole units or fractional units.

11.3 The Holders of record of the PECs shall not be entitled to any voting rights in respect of the Company by reason of their ownership of the PECs.
