     WHEREAS, Section 7 of the Certificate of Designation of Preferences, Rights and Limitations of Series A Convertible Preferred Stock (the “Designation”) contains conversion price adjustment provisions that would be triggered by the Public Offering; and

In connection with any transfer of the Conversion Shares other than (i) pursuant to an effective registration statement, (ii) to the Company, or (iii) pursuant to Rule 144 (provided that Vision provides the Company with reasonable assurances (in the form of seller and broker representation letters) that the Conversion Shares may be sold pursuant to such rule), the Company may require the transferor thereof to provide to the Company, at the transferor’s expense, an opinion of counsel selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Conversion Shares under the Securities Act.

     (b) Legends. Certificates evidencing the Conversion Shares shall bear any legend as required by the “blue sky” laws of any state and a restrictive legend in substantially the following form, until such time as they are not required under Section 6(c) or applicable law:

     THESE SECURITIES HAVE NOT BEEN REGISTERED] UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OR (B) AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS OR BLUE SKY LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY AND ITS TRANSFER AGENT OR (II) UNLESS SOLD PURSUANT TO RULE 144 UNDER SAID ACT. NO REPRESENTATION IS MADE BY THE ISSUER AS TO THE AVAILABILITY OF THE EXEMPTION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT FOR RESALES OF THESE SECURITIES.

     (c) Removal of Legends.

requirement for the Company to be in compliance with the current public information required under Rule 144 as to such securities and without volume or manner-of-sale restrictions.
