Limitations and Qualifications:

Whenever our opinion in this letter with respect to the existence or absence of facts is qualified by the phrase “to the best of our knowledge”, “to our actual knowledge,” “to our knowledge,” “aware” or terms of similar import, it is intended to signify that during the course of our representation of the Nevada Guarantors no information has come to the attention of lawyers currently members of or associated with this firm who have performed services on behalf of the

Nevada Guarantors that would give us actual knowledge of any facts inconsistent with this opinion. We have not undertaken any independent investigation to determine the existence or absence of those facts (including examining files maintained by this firm and relating to the Nevada Guarantors), and no inference as to our knowledge of the existence or absence of those facts shall or may be drawn from our representation of the Nevada Guarantors.

We call your attention to the fact that the Indenture states that it is to be governed by the laws of the State of New York. We are not familiar with the laws of the State of New York and render no opinion as to such laws. For the purposes of our opinion, we have assumed, with your consent and without independent investigation, that the Indenture will be governed by the laws of the State of Nevada notwithstanding its express terms.

As to various questions of fact material to this opinion, we have relied upon the truth and completeness of the representations and warranties made by all parties in the Indenture, the Registration Statement and the Formation and Authority Documents.

We have not reviewed, and express no opinion as to, any instrument or agreement referred to or incorporated by reference in the Indenture.

We are admitted to practice in the State of Nevada, and our opinion is limited to matters under or involving the laws of the State of Nevada. We express no opinion as to matters under or involving the laws of any jurisdiction other than the laws of the State of Nevada (except for gaming, securities or Blue Sky laws on which we express no opinion).

This letter is issued in the State of Nevada, and by issuing this letter the law firm of Rice Silbey Reuther & Sullivan, LLP shall not be deemed to be transacting business in any other state. Furthermore, by issuing this letter the law firm of Rice Silbey Reuther & Sullivan, LLP does not consent to the jurisdiction of any state but the State of Nevada, and any claim or cause of action arising out of the opinions expressed herein must be brought in the State of Nevada.

This opinion is furnished to you in connection with the filing of the Registration Statement and is not to be used, circulated, quoted or otherwise relied upon for any other purpose, except that Kirkland & Ellis LLP may rely upon this opinion to the same extent as if it were an addressee hereof.

We hereby consent to the filing of this opinion with the commission as Exhibit 5.3 to the Registration Statement. We also consent to the reference to our firm under the heading “Legal Matters” in the Registration Statement. In giving this consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission.

The opinions expressed in this letter are rendered as of the date hereof, and we express no opinion as to circumstances or events that may occur subsequent to such date. We expressly disclaim any responsibility to advise you of any development or circumstance of any kind, including any change of law or fact, that may occur after the date of this opinion letter even though such development, circumstance or change may affect the legal analysis, a legal

conclusion or any other matter set forth in or relating to this letter. Accordingly, any of you who may rely on this letter at any future time should seek advise of your counsel as to the proper application of this letter at such time.
