1.2      Terms used but not otherwise defined herein shall have the meaning
         ascribed thereto in the Senior Credit Agreement or the High Yield
         Subordination Agreement.

2.       LOAN PRINCIPAL AND DRAWDOWN

         The Lender shall, on the date of this Agreement, advance to the
         Borrower upon the terms hereof a loan in the amount of EUR 550,000,000
         (in words: Euro five hundred and fifty million) (the "LOAN"). The Loan
         shall be made available by the Lender to the Borrower for value on the
         date of this Agreement to such accounts as specified in the Payment
         Instructions.

3.       TERM OF THE LOAN

3.1      Subject to Clause 5, the Loan shall be repaid in one sum five Business
         Days prior to June 1, 2011 (the "REPAYMENT DATE").

3.2      Subject to Clause 5, the Borrower shall procure that an amount equal to
         the aggregate principal amount of any High Yield Notes required to be
         repurchased, redeemed or

<Page>

         repaid (whether at maturity, upon acceleration or otherwise or at the
         option of the Lender or otherwise) in accordance with the terms and
         conditions thereof shall be paid by the Borrower in prepayment of the
         Loan together with all other amounts (including, without limitation,
         interest) relating to the aggregate principal amount of such High Yield
         Notes owing by the Borrower. Any prepayment required to be made under
         this Clause 3.2 shall be made no earlier than five Business Days prior
         to the date upon which the Lender is required (or, as the case may be,
         wishes) to make such repurchase, redemption or repayment and the Lender
         hereby undertakes to notify the Borrower of such repurchase, redemption
         or repayment as soon as reasonably practicable after the date upon
         which it becomes aware of such repurchase, redemption or repayment.

3.3      The Borrower may not prepay or repay any or all of the Loan save as set
         forth in this Clause 3.

4.       INTEREST

4.1      The Loan shall accrue interest at a rate of 10.375% per annum
         (calculated on the basis of a 360-day year of twelve 30-day months);
         provided, however, that such rate shall be adjusted if and to the
         extent necessary to match any additional interest accruing on the High
         Yield Notes in respect of additional amounts payable under applicable
         tax gross-up provisions of the High Yield Notes and any special
         interest payable in the event of a registration default in respect of
         the High Yield Notes.

4.2      Subject to Clause 5, interest will be payable semi-annually in arrears
         no earlier than five Business Days prior to June 1 and December 1 of
         each year.

4.3      Payment of interest which has accrued but cannot be paid by reason of
         any restriction under Clause 5 below, shall be deferred as set out in
         Clause 5.2 below until the first date thereafter on which such payment
         is not so restricted, at which date it shall be due for payment.

5.       RESTRICTION ON PAYMENTS

5.1      Until the Discharge Date and notwithstanding any other provision of
         this Agreement, this Loan shall be subject to the terms of the High
         Yield Subordination Agreement, in particular neither the Lender nor the
         Borrower shall be entitled to make, receive or request any payment
         under this Agreement except as permitted in each case under the Senior
         Credit Agreement and the High Yield Subordination Agreement.

5.2      Subject to the second sentence of this Clause 5.2, any payment (whether
         principal, interest or otherwise) which would be due but cannot be paid
         by reason of Clause 5.1 shall be deferred (EINREDE DER STUNDUNG) until
         the first date thereafter on which such payment is not restricted under
         Clause 5.1, at which date it shall be due for payment.

                                      -5-

<Page>

         After the end of any Standstill Period (as defined in the High Yield
         Subordination Agreement), such payment shall cease to be so deferred in
         relation to an amount due and owing under this Agreement equal to the
         lesser of (i) the then outstanding amount due and owing under this
         Agreement and (ii) EUR 2,500,000, it being understood that any payment
         restrictions set out in the High Yield Subordination Agreement shall
         apply to such amount notwithstanding such exemption from the deferral.

6.       MISCELLANEOUS

6.1.1    The Borrower shall promptly indemnify the Lender against any reasonable
         cost or expense incurred by the Lender (A) in order to meet its
         obligations to pay (i) fees, (ii) costs and expenses relating to the
         offering, sale and exchange, financial reporting, listing, SEC
         registration and reporting and ongoing administration under any
         agreement related to the High Yield Notes, (iii) audit fees, (iv) legal
         expenses, (v) management fees and other expenses, or (B) in order to
         pay any other proper and necessary incidental expenses and other
         payments to enable the Lender to meet its obligations for the payment
         of administrative costs under any registration rights agreement and the
         purchase agreement, both entered into or to be entered into by the
         Lender in relation to the High Yield Notes, the Indenture and a paying
         agency agreement to be entered into by the Lender and a certain paying
         agent, in connection with the High Yield Notes.

6.1.2    The Borrower shall have the right to discharge the indemnity under this
         Clause 6.1 by directing the Lender in writing to pay (or direct the
         payment of) any such aforementioned costs and expenses directly or
         indirectly out of the proceeds of issue of the High Yield Notes
         (including, but without limitation, through the giving of Payment
         Instructions).

6.1.3    For the avoidance of doubt, the Borrower is not obliged under this
         Clause 6.1 to indemnify the Lender for any cost, expense or other
         payment either of, or relating to, interest or principal under the High
         Yield Notes.

6.2      Each of the parties hereby agrees not to amend, modify, release, cancel
         or waive any term of this High Yield Proceeds Loan Agreement without
         the prior written consent of the Trustee (acting in accordance with
         instructions from a majority of beneficial owners of the Notes), except
         as expressively provided for in the High Yield Subordination Agreement.

6.3      This Agreement shall be governed by and construed in accordance with
         German Law.

6.4      Exclusive place of jurisdiction for any disputes arising from or in
         connection with this Agreement shall be Frankfurt am Main.

                                        -6-

<Page>

6.5      All amendments to this Agreement or any waiver with regard to this
         Agreement (including this Clause 6.5) shall be made in writing.

6.6      If, at any time, one or more provisions hereof is or become invalid,
         illegal or unenforceable in any respect under the laws of any
         jurisdiction, such provision shall, as to such jurisdiction, be
         ineffective to the extent necessary without affecting or impairing the
         validity, legality and enforceability of the provisions hereof or of
         such provision in any other jurisdiction. The parties agree that such
         illegal, invalid or unenforceable provision shall be deemed replaced by
         such provision which comes as close as possible to the purpose of this
         Agreement.
