Other than as expressly stated herein, we express no opinion as to whether the Registration Statement is accurate, true, correct, complete and not misleading, or as to any tax matters. In particular, and without limitation to the foregoing, we express no opinion on whether the Registration Statement provides sufficient information for knowledgeable investors to allow for an informed assessment of the Companies and the quotas. In addition, we have not been responsible for investigating or verifying the accuracy of the facts including the business, financial and economic information contained in the Registration Statement or that no material facts has been omitted therefrom.
