(1) The registrant is hereby registering such indeterminate number of shares of common stock and preferred stock, such indeterminate amount of warrants to purchase common stock or preferred stock, such indeterminate amount of rights to purchase securities registered hereunder, such indeterminate number of units as may be sold from time to time, and such indeterminate amount and number of each identified class of the identified securities as may be issued upon conversion, exchange or exercise of any other securities that provide for such conversion, exchange or exercise, which collectively shall have an aggregate initial offering price not to exceed $100,000,000. In addition, pursuant to Rule 416 under the Securities Act, this Registration Statement shall include any additional shares that may become issuable as a result of any stock split, stock dividend, recapitalization or other similar transaction effected without the receipt of consideration that results in an increase in the number of the registrant’s outstanding common stock. Any securities registered hereunder may be sold separately or as units with the other securities registered hereunder.

(2) The proposed maximum initial offering price per unit will be determined, from time to time, by the registrant.

(3) Estimated solely for the purpose of calculating the registration fee pursuant to Rule 457(o) under the Securities Act of 1933, as amended. In no event will the aggregate initial offering price of all securities issued from time to time pursuant to this registration statement exceed $100,000,000.

(4) Calculated in accordance with Section 6 of the Securities Act and Rule 457 under the Securities Act by multiplying .00011610 and the proposed maximum aggregate offering price.

(5) Reflects the deregistration of $19,327,500 in securities that were not sold prior to the termination of the offering.

(6) The $11,610 registration fee was paid upon the filing of the original registration statement. The registration fee for the proposed maximum aggregate offering price (after deregistration of $19,327,500 in securities pursuant to this Post-Effective Amendment No. 1) of $80,672,500 is equal to $9,367.

This Post-Effective Amendment No. 1 relates to registration statement File No. 333-176887 on Form S-3 (the “Registration Statement”) of Amerigon Incorporated (the “Company”), registering $100,000,000 in common stock, preferred stock and warrants, which was filed with the Securities and Exchange Commission on September 16, 2011.
