E. As we will not be present at Closing, we further assume that the Washington Subsidiary Guarantor has delivered the Transaction Documents to which it is a party.

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

Our representation of the Washington Subsidiary Guarantor is limited by those specific matters for which we have been engaged. We have no familiarity with the Washington Subsidiary Guarantor’s day-to-day operations, business or financial affairs.

Additionally, we disclaim any opinion as to the application of any law of any city, county or other local subdivision or other local governmental authority of the State of Washington. To the extent that any of the documents reviewed by us in connection with this opinion are governed by the laws of any jurisdiction other than the State of Washington, our opinion relating to those documents is based solely upon the apparent meaning of the language without regard to interpretation or construction that might be indicated by the laws governing those agreements and instruments. This opinion is limited to the matters expressly set forth above, and no opinion is implied or may be inferred beyond the matters expressly so stated. We assume no obligation to advise the Issuers or the Washington Subsidiary Guarantor of any future changes in the facts or law relating to the matters covered by this opinion.
