D. The parties hereto have agreed to amend the Joint Venture Agreement, inter alia, to:

(v) oblige NLM to pay to the Company not later than ten (10) Business Days before 31 March 2009 an amount equal to 50% of the par value of Notes subscribed for by AerCap.

(a) Notwithstanding anything to the contrary in clause 13.4 of the Joint Venture Agreement (as amended pursuant to the terms of this Agreement), it is agreed that US$70,000,000 of the Additional Shareholder Capital shall be contributed to the Company not by way of subscription for Shares by the Shareholders but rather by AerCap subscribing for US$70,000,000 of Notes pursuant to the terms of this Agreement and the Joint Venture Agreement (as amended by this Agreement) provided that it is acknowledged and agreed by NLM, the Company and AerCap that the failure by AerCap to subscribe for any or all of the Notes in accordance with the Joint Venture Agreement (as amended) shall not constitute an Event of Default or a Financing Event of Default. NLM acknowledges and agrees that it shall have no recourse against AerCap (whether at law, in equity or howsoever otherwise) if AerCap fails to subscribe for any or all of the Notes in accordance with the Joint Venture Agreement (as amended). For the avoidance of doubt, the agreement by NLM in the preceding sentence shall not affect, or be construed to affect, the rights of the Company against AerCap in respect of any breach by AerCap of its obligations hereunder to subscribe for Notes.

(b) In order to reflect the rights and obligations of AerCap, NLM and the Company in respect of such Notes, the following text shall be inserted in the Joint Venture Agreement as a new clause 13.5 and the existing clauses 13.5 and 13.6 shall be renumbered as 13.6 and 13.7 respectively:

“13.5 (a) On any date on or before a Note Financing Start Date the Cash Manager shall by notice in writing (the “Note Call Notice”) require that AerCap shall subscribe at par for Notes under the Loan Note Instrument on any Business Day before the end of the Relevant Quarter (the “Note Due Date”), in such amount as is specified in the Note Call Notice, which amount shall be the amount specified in the column entitled “Note Subscription” in the Equity Drawdown Schedule for the Relevant Quarter provided that the Cash Manager may increase or decrease such amount up to US$10,000,000 in the Note Call Notice (such amount being the “Note Call Amount”) provided further that if the aggregate of the par value of Notes which have been subscribed for by AerCap as at 1 January 2009 (such amount being the “Total Subscribed Note Amount”) is less than US$70,000,000 then the Equity Drawdown Schedule shall be automatically amended such that:

(i) there shall be inserted in the Equity Drawdown Schedule in the column headed “Note Subscription” for the quarter start date “January-09” an amount equal to the difference between US$70,000,000 and the Total Subscribed Note Amount (the “Differential Amount”);

(ii) the amount specified in the column headed “Additional Shareholder Capital” for the quarter start date “January-09” shall be reduced by an amount equal to the Differential Amount; and

(iii) the amount specified in the column headed “Additional Shareholder Capital” for the quarter start date “April-09” shall be increased by an amount equal to the Differential Amount.

(b) AerCap undertakes to the Company to pay the Note Call Amount as set out in any such Note Call Notice in the manner specified in the Note Call Notice and as required by the Loan Note Instrument; and

(c) No later than 30 days before 31 March 2009, the Cash Manager shall issue a notice to NLM requiring it to pay to the Company a cash amount equal to fifty per cent. (50%) of the par value of the Notes subscribed for by AerCap prior to 31 March 2009 (the “Subject Notes”) and not later than ten (10) Business Days before 31 March 2009, NLM shall pay such amount in cash to the Company. Following receipt of such sum, on 31 March 2009 the Company shall issue to NLM Shares fully paid at par having a nominal value equal to the par value of the Subject Notes. The Company shall use all of the subscription proceeds for such Shares to redeem on 31 March 2009 such number of the Notes outstanding on such date as equal the amount of such subscription proceeds. For the avoidance of doubt, the Company shall be entitled to redeem Notes only out of the proceeds of the subscription for such Shares, save where

such redemption is made under clause 7(a) (Acceleration Events) of the Loan Note Instrument.”

(c) NLM acknowledges and agrees that it shall have no rights under clause 15.1 of the Joint Venture Agreement, nor shall article 7.1 of the articles of association of the Company apply, in respect of any Shares issued to the holder of Notes as a result of or in connection with the redemption or conversion of any Notes in accordance with the Loan Note Instrument.

2.3 AerCap, NLM and the Company each hereby unconditionally and irrevocably acknowledge and confirm that save as amended and varied by this Agreement, the Joint Venture Agreement remains in full force and effect and the rights and obligations of each of AerCap, NLM and the Company have not been discharged, impaired or otherwise affected by the execution or performance of this Agreement.

2.4 AerCap, NLM and the Company each hereby agree that, with effect from the date hereof, all references to the Joint Venture Agreement (howsoever described) will be construed as references to the Joint Venture Agreement as amended pursuant to this Agreement, as it may be further amended from time to time.

3. Consent to Loan Note Instrument

3.1 By its execution hereof, and for the purposes of clause 9 of and schedule 4 to the Joint Venture Agreement, each of AerCap and NLM irrevocably consent to:

5. Invalidity

(a) the legality, validity or enforceability in that jurisdiction of any other provision of this Agreement; or

(b) the legality, validity or enforceability in any other jurisdiction of that or any other provision of this Agreement.

The illegal, invalid or unenforceable provision shall be substituted by a valid provision which accomplishes as far as legally possible the economic purposes of the void or unenforceable provision.

6. Governing Law

The provisions of Clause 29 of the Joint Venture Agreement shall apply to this Agreement as if set out in full herein, mutatis mutandis.

7. Miscellaneous

7.1 No neglect, delay or indulgence on the part of any party hereto in enforcing the terms and conditions of this Agreement shall prejudice the strict rights of any party hereunder or be construed as a waiver thereof nor shall this Agreement be capable of variation except in writing signed by the parties hereto.
