Morgan Securities LLC, as representative of the underwriters set forth in Schedule 1 thereto (the “Underwriters”), pursuant to which the Company has agreed to sell to the Underwriters and the Underwriters have agreed to purchase from the Company the Notes. Each capitalized term used but not otherwise defined herein shall have the meaning assigned to such term in the Underwriting Agreement.

In our capacity as counsel to the Company, we have examined copies of:

As to certain matters of fact, we have relied on (i) the representations and warranties of the parties set forth in the Transaction Documents, (ii) certificates, opinions, and other documents delivered by or on behalf of the parties pursuant to the Transaction Documents, (iii) the Fact Certificate, and (iv) the Good Standing Certificates. Our opinions in paragraph (i) and paragraph (iii)(a) are based solely on the Good Standing Certificates. With respect to those portions of the opinions in numbered paragraphs (iv)-(vi) below that concern the due execution of the Transaction Documents by the Company and any Designated Guarantor which is organized under the laws of the State of Delaware, those opinions are based solely upon our review of the Fact Certificate, the charter, bylaws or other constitutive document of each such entity and the counterpart signature pages to the Transaction Documents.

Based on the foregoing and subject to the qualifications hereinafter set forth, we are of the opinion that:

(i)    The Company has been incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware.

(ii)    The Company has corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Time of Sale Information and the Prospectus and to enter into and perform its obligations under the Transaction Documents to which it is a party.

(iii)    (a) Each Designated Guarantor has been incorporated or formed and is validly existing as a corporation or limited liability company, and with the exception of Newhi, Inc., to which the concept of good standing is not applicable, is in good standing under the laws of the jurisdiction of its incorporation or formation, as applicable; and (b) each Designated Guarantor has corporate or limited liability company power and authority to own, lease and operate its properties and to conduct its business as described in the Time of Sale Information and the Prospectus and to enter into and perform its obligations under the Transaction Documents to which it is a party.

(iv)    The Indenture has been duly authorized, executed and delivered by the Company and each Designated Guarantor.

(v)    The Notes have been duly authorized by the Company for issuance and sale pursuant to the Underwriting Agreement and the Indenture and have been duly executed and delivered.

(vi)    The Guarantees of the Notes have been duly authorized for issuance by each of the Designated Guarantors pursuant to the Underwriting Agreement and the Indenture and have been duly executed and delivered. The Guarantees of the Notes have been duly executed by each of the Designated Guarantors.

The opinions set forth above are subject to, and qualified and limited in all respects by, the following qualifications and assumptions:

(1)    We have assumed that each document submitted to us is accurate and complete, that each such document that is an original is authentic, that each such document that is a copy conforms to an authentic original, and that all signatures (other than signatures on behalf of the Company and the Guarantors) on each such document are genuine. We have further assumed the legal capacity of natural persons. We also assumed, with respect to each of the Designated Guarantors which is a Delaware corporation, that the transactions contemplated by the Transaction Documents are necessary or convenient to the conduct, promotion or attainment of the business of such Designated Guarantors and that the restrictions on “business combinations” (as defined in Section 203 of the General Corporation Law of the State of Delaware) are inapplicable to the Transactions Documents and the transactions contemplated thereby. We have not verified any of the foregoing assumptions.

(2)     The opinions expressed herein are limited to matters arising under (a) the General Corporation Law of the State of Delaware, solely with respect to the opinions in numbered paragraphs (i)-(vi) above, and (b) the Delaware Limited Liability Company Act and the Washington Business Corporation Act, solely with respect to the opinions in numbered paragraphs (iii)-(iv) and numbered paragraph (vi) above (collectively, the “Covered Laws”). The opinions expressed in this opinion letter are limited to the laws and administrative and court decrees thereunder that in our experience are applicable to transactions of the type contemplated by the Transaction Documents, and we are not opining on, and we assume no responsibility for, the applicability to or effect on any of the matters covered herein of any other laws, the laws of any other jurisdiction, or the law of any county, municipality or other political subdivision or local governmental agency or authority, or on specialized laws that are not customarily covered in opinion letters of this kind, such as tax, insolvency, antitrust, pension, employee benefit, environmental, intellectual property, banking, insurance, labor, health and safety, and state securities laws.

(3)    The opinions and other statements expressed herein are made as of the date hereof and we do not undertake any obligation to inform you of any changes in the matters set forth herein which occur or may come to our attention after the date hereof.

(4)    There are no agreements or understandings among the parties to the Transaction Documents or third parties that have not been provided to us which would affect any of the opinions expressed herein.

(5)     We express no opinion as to (i) whether a federal court of the United States outside of the State of New York, a state court outside the State of New York, or a foreign court would give effect to the choice of New York law provided for in the Transaction Documents, (ii) whether a federal court of the United States outside the State of New York, or a state court outside the State of New York, would have personal jurisdiction over any party, (iii) whether a federal court of the United States would have subject matter jurisdiction over any action brought against any party or (iv) whether any state or federal court sitting in New York City would have subject matter jurisdiction to adjudicate any controversy related to the Transaction Documents.
