We have also relied upon the factual matters contained in certificates of public officials and the officers of the Company.

conformity to the authentic original documents of all documents submitted to us as copies and that the statements regarding matters of fact in the certificates, agreements and documents that we have examined are accurate and complete.

Based upon the above, and subject to the stated assumptions, exceptions and qualifications, we are of the opinion that, when issued in accordance with the terms of the Equity Plan and any applicable Plan Agreement under the Equity Plan, the Shares will be validly issued, fully paid and non-assessable.
