In our examination of the Documents and in rendering the opinions set forth below, we have assumed without independent investigation (i) the enforceability of the Documents against each party to them (other than the Issuers), (ii) that the authorization, execution and delivery by each of the Issuers of each Document to which it is a party and the consummation by each of the Issuers of the transactions contemplated by them do not violate or result in a breach of or default under the party's charter documents, operating agreements or other organizational documents, as the case may be, (iii) that the Exchange Debentures will be issued as described in the Registration Statement and in the form reviewed by us and that any information omitted from the form will be properly added, (iv) the Grove Holdings LLC 4 genuineness of all signatures, (v) the legal capacity of all individuals who have executed any of the documents which we examined, (vi) the authenticity of all documents submitted to us as originals, (vii) the conformity to the original documents of all documents submitted to us as certified, photostatic, reproduced or conformed copies of validly existing agreements or other documents and (viii) the authenticity of all the latter documents.

Based upon the above, and subject to the stated assumptions, exceptions and qualifications, we are of the opinion that when issued, authenticated and delivered in accordance with the terms of the Indenture and against exchange for the Existing Debentures in accordance with the terms set forth in the Registration Rights Agreement, the Exchange Debentures will be legal, valid and binding obligations of the Issuers enforceable against the Issuers in accordance with their terms. The foregoing opinions are subject to the assumption and qualification that the enforceability of the Indenture and the Exchange Debentures may be limited by (i) bankruptcy, insolvency, fraudulent conveyance or transfer, reorganization, moratorium and other similar laws affecting creditors' rights generally and (ii) general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law).
