Intrexon further acknowledges and understands that the Company may not be satisfying the current public information requirement of Rule 144 at the time Intrexon wishes to sell the shares and, if so, Intrexon would be precluded from selling the shares under Rule 144 even if the one year minimum holding period has been satisfied.

Exhibit A

FORM OF LEGAL OPINION

The Company has been duly incorporated and is a validly existing corporation in good standing under the laws of the State of Nevada.

The Company has the requisite corporate power to own, lease and operate its property and assets, and to conduct its business as described in the SEC Documents.

The Company is duly qualified to do business as a foreign corporation and is in good standing in the State of Michigan.

The Company has the requisite corporate power to execute, deliver and perform its obligations under the Agreement, the PKU Channel Agreement and the Rights Agreement (collectively, the “Transaction Documents”), including, without limitation, to issue, sell and deliver the shares as contemplated by the Agreement.

All corporate action on the part of the Company necessary for the authorization, execution and delivery of the Transaction Documents by the Company, the authorization, sale, issuance and delivery of the shares and the performance by the Company of its obligations to be performed at the Closing under the Transaction Documents has been taken. Each of the Transaction Documents has been duly and validly authorized, executed and delivered by the Company. The Agreement and the Rights Agreement (together, the “Equity Documents”) each constitutes a valid and binding agreement of the Company enforceable against the Company in accordance with its respective terms.

The Company has the authorized capital stock as set forth in the SEC Documents. The shares have been duly authorized and, when issued, sold and delivered against payment therefor in accordance with the terms of the Agreement, will be validly issued, fully paid and nonassessable.

There are no pre-emptive rights or similar rights contained in the Company’s Articles of Incorporation, as amended, or Bylaws, as amended, or any Material Agreement.

The execution and delivery of the Equity Documents and the issuance of the shares pursuant thereto do not violate any provision of the Company’s Articles of Incorporation or Bylaws, do not constitute a default under or a material breach of any Material Agreement and do not (a) violate any U. S. Federal or state statute, rule or regulation which in the experience of such counsel is typically applicable to transactions of the nature contemplated by the Equity Documents or (b) violate any order, writ, judgment, injunction, decree, determination or award which has been entered against the Company and of which such counsel is aware, except, with respect to clauses (a) and (b), where such violation would not materially and adversely affect the Company.

- i -

To the knowledge of such counsel, there is no action, proceeding or investigation pending or overtly threatened against the Company before any court or administrative agency that questions the validity of the Transaction Documents or that could reasonably be expected to result, either individually or in the aggregate, in a material adverse effect on the Company.

10.

All consents, approvals, authorizations, or orders of, and filings, registrations and qualifications with any U.S. Federal or state regulatory authority or governmental body required for the issuance of the shares have been made or obtained, except (a) for the filing of a Form D pursuant to Securities and Exchange Commission Regulation D and (b) and any requisite blue sky filing(s).

11.

Subject to the accuracy of Intrexon’s representations in Section 4 of the Agreement and assuming (a) that neither the Company nor any person acting on behalf of the Company has offered or sold the shares by any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D promulgated (the “Regulation D”) under the Securities Act; (b) that no offerings or sales of securities of the Company after the date hereof in a transaction can be “integrated” with any sales of the shares, the offer and sale of the shares in conformity with the terms of the Agreement constitute transactions that are exempt from the registration requirements of the Securities Act of 1933, as amended, subject to the timely filing of a Form D pursuant to Regulation D.

12.

The Company is not, and, after giving effect to the offering and sale of the shares and the application of the proceeds thereof in accordance with the business plans of the Company to which such counsel is aware, will not be an “investment company” as defined in the Investment Company Act of 1940, as amended.

13.

To the knowledge of such counsel, there are no written contracts, agreements or understandings between the Company and any person granting such person the right (other than rights which have been waived in writing or otherwise satisfied) to require the Company to include any securities of the Company in any registration statement contemplated by Section 2(a) of the Rights Agreement.
