The Seller (or the Servicer on its behalf) will, and will cause each Originator to, at all times, instruct all Obligors to deliver payments on the Pool Receivables to a Lock-Box Account or a Lock-Box. The Seller (or the Servicer on its behalf) will, and will cause each Originator to, at all times, maintain such books and records necessary to identify Collections received from time to time on Receivables and to segregate such Collections from other property of the Servicer and the Originators. If any payments on the Pool Receivables or other Collections are received by the Seller, the Servicer or an Originator, it shall hold such payments in trust for the benefit of the Administrator, the Purchaser Agents and the Purchasers and promptly (but in any event within one Business Day after receipt) remit such funds into a Lock-Box Account. The Seller (or the Servicer on its behalf) will cause each Lock-Box Bank to comply with the terms of each applicable Lock-Box Agreement.

If such funds are nevertheless deposited into any Lock-Box Account, the Seller (or the Servicer on its behalf) will within two Business Days identify and transfer such funds to the appropriate Person entitled to such funds. The Seller will not, and will not permit the Servicer, any Originator or other Person to commingle Collections or other funds to which the Administrator, any Purchaser Agent or any Purchaser is entitled with any other funds, except cash concentration accounts maintained by Meritor, prior to segregation pursuant to Section 1.4 of the Agreement. The Seller shall only add a Lock-Box Account (or the related Lock-Box), or a Lock-Box Bank to those listed on Schedule II to this Agreement, if the Administrator has received notice of such addition and an executed and acknowledged copy of a Lock-Box Agreement in form and substance acceptable to the Administrator from any such new Lock-Box Bank. The Seller shall only terminate a Lock-Box Bank or close a Lock-Box Account (or the related Lock-Box) with the prior written consent of the Administrator.

(i)Clause (f) of Section 2 of Exhibit IV of the Receivables Purchase Agreement is restated as follows:

(f) Payments on Receivables, Lock-Box Accounts. The Servicer will at all times, instruct all Obligors to deliver payments on the Pool Receivables to a Lock-Box Account or a Lock-Box. The Servicer will, at all times, maintain such books and records necessary to identify Collections received from time to time on Receivables and to segregate such Collections from other property of the Servicer and the Originators. If any payments on the Pool Receivables or other Collections

4

704052263 12403015

are received by the Seller, the Servicer or an Originator, it shall hold such payments in trust for the benefit of the Administrator, the Purchaser Agents and the Purchasers and promptly (but in any event within one Business Day after receipt) remit such funds into a Lock-Box Account. The Servicer will cause each Lock-Box Bank to comply with the terms of each applicable Lock-Box Agreement. The Servicer shall not permit funds other than Collections on Pool Receivables and other Pool Assets to be deposited into any Lock-Box Account. If such funds are nevertheless deposited into any Lock-Box Account, the Servicer will within two Business Days identify and transfer such funds to the appropriate Person entitled to such funds. The Servicer will not, and will not permit any other Person to commingle Collections or other funds to which the Administrator, any Purchaser Agent or any Purchaser is entitled with any other funds, except cash concentration accounts maintained by Meritor, prior to segregation pursuant to Section 1.4 of the Agreement. The Servicer shall only add, a Lock-Box Account (or the related Lock-Box), or a Lock-Box Bank to those listed on Schedule II to this Agreement, if the Administrator has received notice of such addition and an executed and acknowledged copy of a Lock-Box Agreement in form and substance acceptable to the Administrator from any such new Lock-Box Bank. The Servicer shall only terminate a Lock-Box Bank or close a Lock-Box Account (or the related Lock-Box) with the prior written consent of the Administrator.

(j)Clause (f) of Exhibit V of the Receivables Purchase Agreement is amended by deleting the percentage “8.50%” where it appears therein and substituting the percentage “9.50%” therefor.

SECTION 2.Consent to Financing Statement Amendment; Agreement Regarding the November 2012 Monthly Information Package. Each of the parties hereto hereby consents to the Administrator filing UCC-3 financing statement amendments substantially in the form attached as Exhibit A hereto.

(c)No Termination Event. No event has occurred and is continuing, or would result from the transactions contemplated hereby or by the PSA Letter Agreement, that constitutes a Purchase and Sale Termination Event, an Unmatured Purchase and Sale Termination Event, a Termination Event or an Unmatured Termination Event.

SECTION 4.Effect of Amendment.
