(the “Issuer”), for an equal principal amount of the Issuer’s outstanding 12.0% Senior Cash Pay Notes due 2014, (ii) the offer to exchange the 13.5% Senior Subordinated Notes due 2015 (the “Subordinated Notes” and together with the Senior Notes, the “Notes”) issued by the Issuer, for an equal principal amount of the Issuer’s outstanding 13.5% Senior Subordinated Notes due 2015, and (iii) the Amendment No. 1 to Registration Statement No. 333-159809 on Form S-4 filed with the Securities and Exchange Commission on July 10, 2009 (the “Registration Statement”) by the Issuer for the purpose of registering the Notes under the Securities Act of 1933, as amended.

In rendering this opinion, we have examined and relied on copies of the following documents in the forms provided to us: the Registration Statement; the Indenture governing the Senior Notes dated as of August 30, 2007 among the Issuer, the Subsidiary Guarantors (as defined therein) and Wells Fargo Bank, N.A., as trustee (the “Trustee”), as supplemented by the Merger Supplemental Indenture dated as of August 30, 2007 between the Issuer and the Trustee, the Supplemental Indenture in respect of Subsidiary Guarantee (the “Senior Notes Supplemental Indenture”) dated as of August 30, 2007 among the Subsidiary Guarantors (as defined therein), the Issuer and the Trustee, and the Third Supplemental Indenture (the “Senior Notes Third Supplemental Indenture”) dated as of October 30, 2007 among the Issuer, the Subsidiary Guarantors (as defined therein) and the Trustee (such Indenture, as so supplemented, the “Senior Notes Indenture”); the Indenture governing the Subordinated Notes dated as of August 30, 2007 among the Issuer, the Subsidiary Guarantors (as defined therein) and the Trustee, as supplemented by the Merger Supplemental

In such examinations, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as copies or drafts of documents to be executed and the legal capacity of natural persons to complete the execution of documents.

will be conducted in accordance with the terms of the Original Partnership Agreement or the Partnership Agreement, as applicable, and the Delaware Revised Uniform Limited Partnership Act, 6 Del. C. §§ 17-101 et seq. (the “Delaware LP Act”); (viii) that no event or circumstance has occurred on or prior to the date hereof that would cause the dissolution of a Guarantor (other than the Partnership) under its respective Original LLC Agreement or LLC Agreement, as applicable, or Section 18-801 of the Delaware LLC Act; (ix) that no event or circumstance has occurred on or prior to the date hereof that would cause the dissolution of the Partnership under the Original Partnership Agreement or the Partnership Agreement, as applicable, or Section 17-801 of the Delaware LP Act; (x) none of the Guarantors owns any property in, or conducts any business or other activities in or regulated by, the State of Delaware other than activities incident to its formation and continued existence as a Delaware limited liability company or Delaware limited partnership, as applicable; (xi) that the Resolutions have been duly adopted, have not been amended, modified or revoked and are in full force and effect on the date hereof; (xii) that prior to its conversion to a Delaware limited liability company, HD Builder (as identified and defined on Annex A hereto) was a duly incorporated, validly existing corporation in good standing under the laws of the State of Delaware; and (xiii) that each of the documents examined by us is in full force and effect, sets forth the entire understanding of the parties thereto with respect to the subject matter thereof and has not been amended, supplemented or otherwise modified, except as herein referenced. We have not reviewed any documents other than those identified above in connection with this opinion, and we have assumed that there are no other documents contrary to or inconsistent with the opinions expressed herein. No opinion is expressed herein with respect to the requirements of, or compliance with, federal or state securities or blue sky laws. In addition, we express no opinion as to, and assume no responsibility for, the Registration Statement or any other offering materials relating to the Notes. As to any facts material to our opinion, other than those assumed, we have relied, without independent investigation, on the above-referenced documents and on the accuracy, as of the date hereof, of the matters therein contained. For purposes of our opinion set forth in paragraph 7 below, we refer only to requirements for any consent, approval, authorization or order of any governmental agency or body of the State of Delaware, that are of general application and, in our experience, are normally applicable to transactions of the type contemplated by the Transaction Documents (and not to requirements of law that might be implicated by reason of the specific business activities of any of the above-referenced entities).

Based upon and subject to the foregoing and to the further assumptions and qualifications set forth below, and limited in all respects to matters of Delaware law, it is our opinion that:

1.    Each of the Guarantors (other than the Partnership) is a duly formed and validly existing limited liability company in good standing under the laws of the State of Delaware.

2.    The Partnership is a duly formed and validly existing limited partnership in good standing under the laws of the State of Delaware.

3.    Each of the Guarantors (other than the Partnership) has requisite limited liability company power and authority under its respective LLC Agreement and the Delaware LLC Act to enter into the Transaction Documents and to perform its obligations thereunder.

4.    The Partnership has requisite limited partnership power and authority under the Partnership Agreement and the Delaware LP Act to enter into the Transaction Documents and to perform its obligations thereunder.

5.    The execution, delivery and performance by each of the Guarantors (other than the Partnership) of the Transaction Documents have been duly authorized by all requisite limited liability company action.

6.    The execution, delivery and performance by the Partnership of the Transaction Documents have been duly authorized by all requisite limited partnership action.

7.    No consent, approval, authorization or order of any governmental agency or body of the State of Delaware is required to be obtained or made by any Guarantor solely as a consequence of the execution and delivery by such Guarantor of the Transaction Documents, or the performance of its obligations under the Transaction Documents.

8.    The execution and delivery by each of the Guarantors (other than the Partnership) of the Transaction Documents and the performance by such Guarantor of its obligations thereunder will not violate (i) its respective Formation Certificate; (ii) its respective LLC Agreement or (iii) the Delaware LLC Act.

9.    The execution and delivery by the Partnership of the Transaction Documents and the performance by the Partnership of its obligations thereunder will not violate (i) the Partnership Certificate (as identified and defined on Annex D hereto); (ii) the Partnership Agreement or (iii) the Delaware LP Act.

10.    In the event that, notwithstanding the contrary provisions of the Transaction Documents that call for the application of the laws of the State of New York to the construction and interpretation of the Transaction Documents, the substantive laws of the State of Delaware were applied to the construction and interpretation of the Transaction Documents, under the substantive laws of the State of Delaware, each of the Transaction Documents would

constitute a legal, valid and binding obligation of each of the Guarantors, enforceable against the such Guarantor in accordance with its terms.

The opinions expressed above are subject to and limited by (i) bankruptcy, insolvency, reorganization, receivership, fraudulent conveyance, fraudulent transfer, moratorium or other laws of general application relating to or affecting the enforcement of creditors’ rights and remedies, as from time to time in effect, (ii) application of equitable principles (regardless of whether such enforceability is considered in a proceeding in equity or at law), (iii) considerations of public policy and (iv) standards of good faith, fair dealing, course of dealing, materiality and reasonableness that may be applied by a court to the exercise of rights and remedies and the possible unavailability of the remedy of specific performance or other equitable relief; provided, further, that the provisions of Section 1301(e) of each of the Senior Notes Indenture and the Subordinated Notes Indenture may be subject to the provisions of Section 3912 of Title 10 of the Delaware Code. In addition, we express no opinion with respect to the enforceability of (A) the Transaction Documents against or with respect to any person or entity who or which is not a party thereto; (B) any other document referenced in the Transaction Documents; and (C) any purported waiver or consent granted by any party pursuant to the Transaction Documents except to the extent such party may so waive or consent and has effectively so waived or consented in accordance with applicable law.

We hereby consent to the filing of a copy of this opinion with the Securities and Exchange Commission as an exhibit to the Registration Statement and to the reference to our firm under the heading “Legal Matters” in the prospectus included in the Registration Statement. In giving this consent, we do not thereby admit that we come within the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended, or the rules and regulations of the Securities and Exchange Commission thereunder. We understand that Debevoise & Plimpton LLP wishes to rely as to certain matters of Delaware law on the opinion expressed herein in connection with the rendering of its opinion dated on or about the date hereof and we hereby consent to such reliance. Except as provided in this paragraph, the opinion set forth above is expressed solely for the benefit of the addressees hereof in connection with the matters contemplated hereby and may not be relied upon for any other purpose or by any other person or entity without our prior written consent. This opinion speaks only as of the date hereof and is based on our understandings and assumptions as to present facts and our review of the above-referenced documents and the application of Delaware law as the same exist on the date hereof, and we undertake no obligation to update or supplement this opinion after the date hereof for the benefit of any person or entity with respect to any facts or circumstances that may hereafter come to our attention or any changes in facts or law that may hereafter occur or take effect.

Very truly yours,
