Case New Holland Inc. Form F-4 Registration Statement 2011

Ladies and Gentlemen,

1. DESCRIPTION OF TRANSACTION

This opinion is furnished to you in connection with the registration statement on Form F-4 (the “Registration Statement”) filed by Case New Holland Inc., a Delaware corporation (the “Company”), CNH Global, N.V., a Netherlands public limited liability company (the “Parent”), and certain subsidiaries of the Parent named therein as guarantors (collectively with the Parent, the “Guarantors”), including CNH Deutschland GmbH (the “German Guarantor”) with the United States Securities and Exchange Commission (the “Commission”) under the United States Securities Act of 1933, as amended (the “Securities Act”), relating to the registration of USD 1,500,000,000 principal amount of the Company’s 7 ⁷/8% senior notes due 2017 (the “New Notes”) which are to be offered in exchange for an equivalent principal amount of presently outstanding 7 ⁷/8% senior notes due 2017 (the “Old Notes”), as more fully described in the Registration Statement. The Old Notes are, and the New Notes will be, guaranteed by the Guarantors (the “Guarantees” and each a “Guarantee”). Old Notes that are accepted in exchange for New Notes will be cancelled and retired.

The Old Notes were and the New Notes will be issued under an indenture, dated as of June 28, 2010 (the “Indenture”), by and among the Company, the Guarantors and Wells Fargo Bank, N.A. as trustee (the “Trustee”). The Indenture and the Guarantees are collectively referred to as the “Documents”.

4. OPINION

Based upon the foregoing and subject to the qualifications set out herein, we are of the opinion that:

4.1 Status: The German Guarantor is a limited liability company (Gesellschaft mit beschränkter Haftung) duly incorporated and validly existing under the laws of the Federal Republic of Germany.

4.2 Powers and Authority: The German Guarantor has full corporate power and authority to enter into the German Guarantee and to perform its obligations thereunder, and all corporate action required pursuant to its articles of association (Gesellschaftsvertrag/Satzung) of the German Guarantor and pursuant to generally applicable company law (Gesellschaftsrecht) to authorize the execution and delivery of the German Guarantee on its behalf and the performance of its obligations thereunder has been duly taken.

4.3 Due Authorization and Execution: At the time of its execution, the Indenture has been duly authorized and executed by the German Guarantor.

5. QUALIFICATIONS

Our opinions are subject to the following qualifications:

3

5.1 We note that under applicable German corporate law (Sections 30, 31 of the German Act on Limited Liability Companies (Gesetz betreffend die Gesellschaften mit beschränkter Haftung, “GmbHG”), the granting of an upstream guarantee by a German limited liability company (“GmbH”) to an affiliate may violate Sections 30, 31 GmbHG, if the payment under such guarantee would cause the net assets of the GmbH to fall under its stated share capital (Stammkapital), or, if the net assets of the GmbH are already less than the stated share capital, cause the net assets to be further reduced, save for cases where the GmbH granting the guarantee has a fully valuable (voll werthaltigen) claim for loss compensation under a profit and loss transfer agreement and/or a domination agreement (Ergebnisabführungs- oder Beherrschungsvertrag) or a direct claim against the affiliate or its shareholder for indemnification (Freistellungs- oder Aufwendungsersatzanspruch) with respect to the guarantee such that the amount of losses resulting from the enforcement of the guarantee is fully recoverable (werthaltig). The terms of the German Guarantee limit enforcement of the German Guarantee, inter alia, if and to the extent payment under the German Guarantee or the application of enforcement proceeds would cause the net assets of either CNH Deutschland GmbH or CNH Baumaschinen GmbH, with which CNH Deutschland GmbH has entered into a profit and loss transfer agreement (or that of another future GmbH-shareholder with which CNH Deutschland GmbH has entered into a profit and loss transfer agreement), to fall below such entity’s respective registered share capital and thereby cause a violation of Section 30 GmbHG. We further note that both CNH Deutschland GmbH and CNH Baumaschinen GmbH currently have negative equity under German GAAP and that under the limitations set forth in the terms of the German Guarantee, the noteholders may not be able to enforce the German Guarantee as long as CNH Deutschland GmbH and/or CNH Baumaschinen GmbH continue to have negative equity.

5.2 Pursuant to several decisions of the German Federal Court of Justice (Bundesgerichtshof) with respect to Sections 30 and 31 GmbHG, a security interest (including a guarantee) granted by a GmbH for the benefit of any affiliated company (within the meaning of sections 15 et seq. of the German Stock Corporation Act (Aktiengesetz, “AktG”) other than its direct or indirect subsidiaries (the “Affiliates”) to third party creditors may be held invalid pursuant to Section 138 of the German Civil Code (Bürgerliches Gesetzbuch, “BGB”) and would therefore not be enforceable if, at the time of the creation of the security interest, (i) the enforcement of the security interest would cause the GmbH’s equity (Eigenkapital) to fall below the amount of its stated capital (Stammkapital) and (ii) the third party creditor and the Affiliates have acted in fraudulent conveyance (kollusives Zusammenwirken) to the detriment of the GmbH or other third party creditors of the GmbH.

5.3 Pursuant to several decisions of the German Federal Court of Justice (Bundesgerichtshof) the shareholders of a German GmbH may be held personally liable for causing the insolvency of such GmbH (existenzvernichtender Eingriff). Therefore, German courts may determine that the validity and enforceability of claims of a third party creditor under the Documents and any documentation relating thereto against a GmbH may be limited or such claims may be void, as the case may be, if the execution of the Documents (and any documentation relating thereto) or the performance of the obligations of such GmbH under the Documents (and any documentation relating thereto) could be viewed as an insolvency-causing interference (existenzvernichtender Eingriff) by the shareholders of such GmbH, and the third party creditor and the shareholders have acted in fraudulent conveyance (kollusives Zusammenwirken) to the detriment of the GmbH or other third party creditors of the GmbH. There is – in the absence of a yet predominant view (herrschende Meinung) among legal commentators – no certainty as to the actual interpretation by a German court of the principles set forth in the aforecited decisions of the German Federal Court of Justice as applied to the Documents.

5.4 According to the established practice of the German Federal Court of Justice (Bundesgerichtshof), a company which in fact commenced doing business is generally validly existing until it is dissolved despite any defects during the process of incorporation or establishment. However, certain defects in the process of incorporation or establishment of a company may result in the company being null and void ex tunc (e.g. a founder has been deceited when incorporating or establishing the company, forced to incorporate or to establish the company or has lacked full legal capacity when incorporating or establishing the company).

4

5.5 Our opinions are subject to the effect of any applicable bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers and contestability (insolvenzrechtliche Anfechtbarkeit)), reorganization, liquidation, moratorium or other similar laws affecting creditors’ rights generally.

5.6 Our opinions are subject to the effect of general principles of German law, including, but not limited to, the principle of loyalty and good faith (Treu und Glauben).

6. OPINION LIMITED TO GERMAN LAW

Our opinions expressed above are limited to the law of the Federal Republic of Germany, and we have not investigated the laws of any country other than the Federal Republic of Germany and we assume that no foreign law or directive or regulation or ruling affects any of the conclusions stated above and we do not express any opinion herein concerning any other law or with respect to any tax-related matters.
