Item 8.01 Other Events.

On June 1, 2012, QuickLogic Corporation (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with Roth Capital Partners, LLC (the “Underwriter”) relating to a public offering (the “Offering”) of an aggregate of 4,500,000 shares of the Company’s common stock, par value $0.001 per share, together with warrants to purchase up to 2,025,000 shares of common stock. The common stock and warrants will be sold as units (the “Units”), with each Unit consisting of (i) one share of common stock and (ii) a warrant to purchase 0.45 of a share of common stock, at a price of $2.50 per Unit. The warrants are exercisable any time after the date of issuance until the 60 month anniversary of the date of issuance, and will be exercisable at a price of $2.98 per share. In addition, under the terms of the Underwriting Agreement, the Company granted the Underwriter a 30 day option to purchase up to an additional 675,000 shares of common stock and/or warrants to purchase up to an additional 303,750 shares of common stock to cover overallotments, if any. The Offering is expected to close on June 6, 2012. The net proceeds to the Company from the Offering, excluding the proceeds, if any, from the exercise of warrants in this Offering, are expected to be approximately $10.49 million, after deduction of underwriting discounts and assuming no exercise of the Underwriter’s overallotment option.

The Offering was made pursuant to the Company’s effective registration statement on Form S-3 (Registration Statement No. 333-161501) and Form S-3MEF (Registration Statement No. 333-181819) (collectively, the “Registration Statement”) previously filed with and declared effective by the Securities and Exchange Commission (the “SEC”) and a prospectus supplement thereunder filed with the SEC.

The Underwriting Agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company and the Underwriter, including for liabilities under the Securities Act of 1933, as amended, other obligations of the parties and termination provisions.
