The exhibit required by Regulation S-K Item 601(b)(8) must include an opinion of what the tax consequences of the transaction are. It is insufficient to file an exhibit that simply opines on the accuracy of your disclosure. 50. The exhibit required by Regulation S-K Item 601(b)(8) may not assume conclusions of law which are a necessary requirement of the ultimate opinion. Please file an opinion that does not include (a) assumptions regarding the due execution and delivery of all documents where due execution and delivery are prerequisites to the effectiveness thereof or (b) the assumptions in clause (iv) in the first full paragraph on page 2. 51. Given the statement that counsel does not undertake to advise of any subsequent changes of the facts stated or assumed in the opinion or of any new developments in the application or interpretation of the federal income tax laws, please be advised that you will need to file a new opinion prior to effectiveness of the registration statement. 52.

Likewise, the opinion you file should clarify whether the third paragraph and the penultimate paragraph mean that counsel relied on others for legal conclusions. Exhibit 99.1 54.
