Title to the Future Collateral brought to any Premises shall pass over to the Administrative Agent (at the latest), when it is identified in the (updated) Asset List. 2.3 To the extent that the relevant Transferor has only co-ownership (Miteigentum) of Transferred Goods or the relevant Transferor has any inchoate rights (Anwartschaftsrechte) in respect of Transferred Goods, the relevant Transferor hereby transfers to the Administrative Agent such co-ownership or inchoate rights, and it is agreed that the transfer of ownership, co-ownership, or inchoate rights in respect of Transferred Goods takes place on the date hereof or on the date the relevant Transferor acquires ownership, co-ownership or inchoate rights in respect of such Transferred Goods (the Transferred Goods together with the ownership, co- ownership, or inchoate rights are hereinafter referred to as the "Transferred Assets"). 2.4 In lieu of transfer of possession of the Transferred Assets to the Administrative Agent the Parties agree that the relevant Transferor shall hold the Transferred Assets in gratuitous custody (unentgeltliche Verwahrung) for the Administrative Agent. Each Transferor hereby further assigns all present and future claims against third parties obtaining actual possession of any of the relevant Transferred Assets to the Administrative Agent, who accepts such assignment. 2.5 Each Transferor and the Administrative Agent agree that any transfer of title to the Collateral Agent shall not be affected (i) by the relevant Transferor (or any servicer on its behalf) relocating any of the Transferred Assets to premises other than the Premises, (ii) relocating any of the Transferred Assets within the relevant Premises (e.g. from one storage place identified in the relevant Asset List (as applicable) to another storage place on such premises, (iii) by the relevant Transferor opening new

Upon delivery of an updated list pursuant to this Clause 4.1, the representations and warranties set out in Clauses 11.5, 11.6 and 11.7 are deemed to be made with respect to the provided information.

Such information shall, to the extent it does not affect the validity and the effectiveness of the security granted hereunder, replace the recent Asset List and shall, form an integral part of this Agreement. Provided that the Administrative Agent has obtained the required information under or in connection with such contingency plan, a failure of the relevant Transferor to provide an up-to date list of Transferred Assets pursuant to the first sentence of this Clause shall not constitute an Event of Default. 4.2 Any updated Asset List shall provide all necessary details for the clear identification of the Transferred Assets including, where applicable, the location of the Transferred Assets (including area on premises, shelve number, number of storage place (as applicable)), the owner of the location (including the relevant landlord or warehouse owner, if applicable) and identification marker, barcode, details of the nature of the Transferred Assets, the number, weight and capacity thereof, and the book value of the Transferred Assets. Each list shall be provided with a self-explanatory legend, unless the legend provided so far is still complete and up-to date. 4.3 If any Transferor employs a third party for its bookkeeping and/or data-processing and/or storage management, upon the occurrence of an Event of Default, each Transferor hereby irrevocably authorises the Administrative Agent to obtain any such lists directly from such third party at the relevant Transferor's costs and expenses and

RETENTION OF TITLE ARRANGEMENTS Each Transferor shall, where appropriate in the ordinary course of business, terminate any retention of title arrangements (Eigentumsvorbehalt) of third parties in respect of any Transferred Assets by paying the purchase price thereof. Upon the occurrence of an Event of Default, which is continuing, the Administrative Agent shall be entitled, but not obliged, to terminate such retention of title arrangements by paying the outstanding purchase price or part thereof on behalf of the Transferor to any such third party. 6. STATUTORY LIEN 6.1 Each Transferor undertakes to use its reasonable efforts that, within sixty (60) days from the date of this Agreement, each landlord (if applicable) waives by written declaration of any statutory liens that it may have as a lessor or landlord or as an owner of Premises under the laws of the Federal Republic of Germany in relation to any of the Transferred Assets of the relevant Transferor.

No such notification shall be required if it were unsuitable under the circumstances (untunlich), in particular if (i) the relevant Transferor has generally ceased to make payments (Zahlungseinstellung), (ii) an application for the institution of insolvency proceedings has been filed by or against the relevant Transferor (Antrag auf Eröffnung eines Insolvenzverfahrens) or insolvency proceedings have been opened (Eröffnung eines Insolvenzverfahrens) against the relevant Transferor, unless in case of an application filed against it, such application is obviously abusive, or (iii) compliance with the notice period would have an adverse effect on the enforcement and realisation of the Transferred Assets. Each Transferor hereby expressly agrees that these notice provisions are sufficient and the Administrative Agent shall not be obliged to deliver any further notices or proof to the relevant Transferor prior to the realisation of the Transferred Assets. 13.3 At any time after the occurrence of an Event of Default which is continuing, the Administrative Agent may, in its sole discretion, determine which of several security interests (created under this Agreement or elsewhere) shall be used to satisfy the Secured Obligations. 13.4 At any time after the occurrence of an Event of Default which is continuing, the Administrative Agent may request that all documents of title and other documents relating to the Transferred Assets be handed over to it and each Transferor hereby agrees to promptly comply with any such request.

The relevant German Transferor shall at any time, upon the Administrative Agent's reasonable request, provide the Administrative Agent with further and updated evidence showing whether and to which extent its financial condition has improved.
