Item 1.01 – Entry into a Material Definitive Agreement.

Underwriting Agreement

On April 24, 2014, Parametric Sound Corporation (the “Company”) entered into an Underwriting Agreement (the “Underwriting Agreement”) with Needham & Company, LLC, as representative for the several other underwriters named therein, relating to an underwritten public offering (the “Offering”) of 4,000,000 shares of its common stock, $0.001 par value per share, at a price to the public of $10.00 per share (the “Offering Price”). Under the terms of the Underwriting Agreement, the Company granted the underwriters a 30-day option to purchase up to an additional 600,000 shares of common stock at the Offering Price less the underwriting discount and estimated offering expenses payable by the Company. Assuming no exercise of the over-allotment option, the Company expects to receive net proceeds from the Offering of approximately $35.6 million after deducting the underwriting discount and estimated offering expenses payable by the Company. The Company intends to use the net proceeds from the Offering to repay certain indebtedness and for working capital and other general corporate purposes. The shares were delivered to the underwriters on April 29, 2014.

The offering is being made pursuant to the Company’s effective registration statement on Form S-3 (Registration Statement No. 333-188389) previously filed with the Securities and Exchange Commission and a preliminary and final prospectus supplement thereunder. The Underwriting Agreement contains representations, warranties and covenants of the Company that are customary for transactions of this type and customary conditions to closing. Additionally, the Company has agreed to provide the underwriters with customary indemnification rights under the Underwriting Agreement.

A copy of the Underwriting Agreement is filed herewith as Exhibit 1.1 and is incorporated herein by reference. The foregoing description of the Underwriting Agreement does not purport to be complete and is qualified in its entirety by reference to such Exhibit 1.1.

The opinion of the Company’s counsel regarding the validity of the shares issued in the Offering is filed herewith as Exhibit 5.1.
