Ladies and Gentlemen:
We have acted as special counsel to Mattson Technology, Inc., a Delaware corporation (the “Company”), in connection with the offering by the Company of an additional 1,836,750 shares of the Company’s common stock, par value $0.001 per share (the “Option Shares”), pursuant to a Registration Statement on Form S-3 (Registration No. 333-191686), as amended (the “Registration Statement”), filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”), and declared effective on November 7, 2013, the related prospectus dated November 7, 2013 (the “Base Prospectus”), and the related prospectus supplement dated February 10, 2014 relating to the Option Shares filed with the Commission pursuant to Rule 424(b) of the rules and regulations of the Act (the “Prospectus Supplement”). (The Base Prospectus and the Prospectus Supplement are collectively referred to as the “Prospectus.”) All of the Option Shares are to be sold by the Company as described in the Registration Statement and Prospectus.
In connection with this opinion, we have examined and relied upon the originals, or copies certified to our satisfaction, of such records, documents, certificates, opinions, memoranda and other instruments as in our judgment are necessary or appropriate to enable us to render the opinion expressed below. As to certain factual matters, we have relied upon information obtained from public officials, officers of the Company and other sources believed by us to be responsible and have not sought to independently verify such matters. We have assumed (i) the genuineness and authenticity of all documents submitted to us as originals, (ii) the conformity to originals of all documents submitted to us as copies thereof, (iii) the truth, accuracy and completeness of the information, representations and warranties contained in the records, documents, certificates, opinions, memoranda and other instruments we have received, (iv) the legal capacity of all natural persons, and (v) the due execution and delivery of all documents where due execution and delivery are a prerequisite to the effectiveness thereof.
On the basis of the foregoing, and in reliance thereon, we are of the opinion that the Option Shares, when sold and issued in accordance with the Registration Statement and the Prospectus, will be validly issued, fully paid and non-assessable.
