PROSPECTUS SUMMARY The following summary is qualified in its entirety by reference to, and should be read in conjunction with, the more detailed information appearing elsewhere in this Prospectus or incorporated by reference herein. Investors should also carefully consider the information set forth under "Risk Factors." The Company We are a designer, marketer and manufacturer of proprietary high technology electronic components and systems for sale to automotive, truck and other original equipment manufacturers ("OEMs"). We are currently focusing the majority of our efforts on the introduction of our primary product, a Climate Control Seat(TM) ("CCS(TM)") system, which provides year-round comfort by providing both heating and cooling to seat occupants. Additionally, we have a product still under development, our AmeriGuard(TM) radar-based speed and distance sensor system, which alerts drivers to the presence of objects near the vehicle. Climate Control Seat System In the past two years, we have supplied prototype seats containing our CCS system to virtually every major automobile manufacturer and seat supplier. As a result of this process, we were selected by Ford Motor Company ("Ford") to supply our CCS product to Johnson Controls, Inc. ("JCI") for installation in the 2000 model year Lincoln Navigator SUV. According to Automotive News, approximately 43,000 of these vehicles were produced in the 1999 calendar year. The CCS product is currently being offered as an optional feature on this vehicle, replacing the traditional seat heater. Initial production shipments to JCI commenced in late November 1999. On March 27, 2000, we entered into a Value Participation Agreement ("VPA") with Ford. Pursuant to the VPA, Ford agreed that, through December 31, 2004, we have the exclusive right to manufacture and supply heated and cooled or heated and ventilated seats to Ford's tier 1 suppliers for installation in Ford, Lincoln and Mercury branded vehicles produced and sold in North America (other than Ford branded vehicles produced by AutoAlliance International, Inc.). Ford is not obligated to purchase any CCS units under the VPA. We are also in pre-production preparation to supply our CCS product to a major Japanese automotive manufacturer for installation in a 2001 model year luxury vehicle. We are working with many other automotive OEMs and their seat suppliers in an effort to have the CCS product included in other models commencing with the 2002 model year and beyond. We currently have active development programs on nine other vehicle platforms, but no assurance can be given that our CCS system will be implemented in any of these vehicles. Currently, we are enjoying several competitive advantages including: Innovative product - our CCS system is the only product currently offered that provides both active heating and cooling for automotive seats; Proprietary technology - we own three patents, exclusively license three other patents and have one patent application pending relating to our CCS technology; 3

Time to market - it typically takes approximately five years for a new component to be developed and introduced in a new automotive model, which creates a significant barrier to entry for competing products and technologies; and Seasoned automotive management team - our management team has substantial experience in the automotive industry, both individually and collectively. CCS System Market Opportunity By providing both a heating and cooling solution, we believe that the potential market for the CCS system is much larger than just the heated seat market alone. Some of the characteristics for this market opportunity include: Approximately 56 million cars and light trucks were sold worldwide in 1999 (Source: Automotive News); Assuming 2 front seats per vehicle, 112 million front seats are sold annually; and The Company estimates that between 12 to 15 million traditional electric resistance heated seats are sold in new automobiles each year. New entrants to the automotive components industry that wish to produce and supply innovative seating components must undergo a rigorous qualification process, which takes approximately five years. We believe that in addition to deterring new entrants, the existence of this qualification process represents switching costs for module integrators that are required to assist the new supplier in meeting automakers' requirements. Additionally, we believe module integrators are, like their automaker customers, trying to limit the number of suppliers. CCS Strategy Our strategy is to build upon the existing relationships currently in place between automobile manufacturers and their suppliers and to become the leading provider of climate controlled seating to the automotive marketplace. Key elements of our strategy include: Continuing to partner with major automotive seat companies; Completing the next generation of the CCS technology; Increasing global penetration with global automotive companies; and Continuing to expand our intellectual property. AmeriGuard Radar System Our AmeriGuard product is still under development, although we have sold AmeriGuard prototypes to various automotive and other companies. We are initially marketing it primarily as a backup warning system (BWS) for heavy trucks. We have been engaged in a multiphase test of our system with the New Mexico State Highway and Transportation Department and have recently delivered sixty systems to them for evaluation. In addition, we are currently working to obtain a development program with one of the world's leading suppliers of lighting systems for trucks and buses with a goal of 4

integrating our radar product into its lighting systems for heavy trucks. Our radar technology has many advantages over the other technologies currently in use: Our radar sensors transmit and receive through the plastics typically used in bumper assemblies and lamp lenses; Our radar products operate in rain, snow and when coated with thin layers of ice; and Our radar utilizes solid-state electronics which require no maintenance or calibration. Recent Developments As a result of the extensive knowledge of thermoelectric technology obtained during the development of the CCS product, we have decided to establish a formal research and development program whereby improvements in thermoelectric technology will be pursued. The objective of this effort will be to expand and exploit the application of thermoelectric devices beyond CCS and to non- automotive applications. In June 2000, we raised $12.5 million in gross proceeds from a private placement of 2,500,000 shares of our common stock at an offering price of $5.00 per share. Corporate History We were incorporated in California in 1991 and originally focused our efforts on developing electric vehicles and high technology automotive systems. Because the electric vehicle market did not develop as rapidly as anticipated, we substantially scaled back our efforts in that area beginning in 1997 and completely disposed of our electric vehicle business in June 1999. Our headquarters are located at 5462 Irwindale Avenue, Irwindale, California 91706, telephone (626) 815-7400. 5

RISK FACTORS Investment in our common stock is speculative and involves a high degree of risk. You should only purchase shares if you can afford to lose your entire investment. In deciding whether to buy our common stock, you should carefully consider the following risk factors, the other information contained in this prospectus and the other information we have incorporated by reference. Risks Relating to the Company's Business - ---------------------------------------- Early Stage of Commercialization Although we began operations in 1991, we are only in the early stages of commercial manufacturing and marketing of our products. We originally focused our efforts on developing electric vehicles and other automotive systems. Because the electric vehicle market did not develop as rapidly as we anticipated, we substantially scaled back our efforts in that area beginning in 1997 and completely disposed of our electric vehicle business in June 1999 to focus completely on our CCS and radar products. In December 1997, we received our first production orders for our CCS product, but shipments of production units in 1998 were very small. We were selected by Ford to supply our CCS product to JCI for installation in the 2000 model year Lincoln Navigator SUV. The CCS product is currently being offered as an optional feature on this vehicle and we commenced initial production shipments to JCI in late November 1999. There can be no assurance that sales will significantly increase, or that we will become profitable. Substantial Operating Losses Since Inception We have incurred substantial operating losses since our inception. As of December 31, 1999 and December 31, 1998, we had accumulated deficits since inception of $43,880,000 and $36,305,000, respectively. Our accumulated deficits are attributable to the costs of developmental and other start-up activities, including the industrial design, development and marketing of our products and a significant loss incurred on a major electric vehicle development contract. Of the $23 million we spent between inception and 1996, $18 to $21 million of that amount was spent on electric vehicles or integrated voice technology, another discontinued product. As is typical for a development company transitioning for the first time into a production company, we have continued to incur losses due to continuing expenses without significant revenues or profit margins on the sale of products, and expect to incur significant losses for the foreseeable future. We have not achieved profitability on a quarterly or annual basis to date and may continue to incur net losses for the foreseeable future. Failure to achieve profitability could deplete our current capital resources and reduce our ability to raise additional capital. We incurred net losses of approximately $5.4 million in 1997, $7.7 million in 1998, $7.6 million in 1999 and $2.1 million in the three months ended March 31, 2000. We had an accumulated deficit of approximately $43.9 million as of December 31, 1999 and approximately $45.9 million as of March 31, 2000. The report of our independent accountants with respect to the audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 1999 states that our recurring losses, negative cash flows from operations, significant accumulated deficit and expectation of incurring future losses raise substantial doubts about our ability to continue as a going concern. We expect to increase our operating expenses significantly, expand our sales and marketing operations and continue to develop and expand our product and service offerings. If increased revenues do not accompany these increased expenses, our business, financial condition and results of operations would be materially adversely affected. 6

Dependence on Acceptance by Consumers; Market Competition We have engaged in a lengthy development process on the CCS product which involved developing a prototype for proof of concept and then adapting the basic system to actual seats provided by various automotive OEMs and their seat suppliers. In the last two years, we have supplied prototype seats containing our CCS system to virtually every major car manufacturer. As a result of this process, we were selected by Ford to supply our CCS product to JCI for installation in the 2000 model year Lincoln Navigator SUV. The CCS product is currently being offered as an optional feature on this vehicle. We commenced initial production shipments to JCI in late November 1999. We are working with many other automotive OEMs and their seat suppliers in an effort to have the CCS product included in other models commencing with the 2001 model year and beyond. We currently have active development programs on nine other vehicle platforms, but no assurance can be given that our CCS system will be implemented in any of these vehicles. Furthermore, there is no assurance that consumers will accept or desire our CCS product, particularly at the prices which will be charged by the OEM for the feature. This may prevent our CCS product from becoming a standard (as opposed to an optional) feature in vehicles and also may prevent other automotive OEMs from adopting our CCS product as an optional or standard feature for other models. Need for Additional Financing As is customary for a company only now initiating production, we have experienced negative cash flow from operations since our inception and have expended, and expect to continue to expend, substantial funds to continue our development and marketing efforts. In addition, as our CCS product now requires production in larger quantities, we will incur increased manufacturing costs. We have not generated and do not expect to generate in the near future sufficient revenues from the sales of our principal products to cover our operating expenses. In addition to the proceeds from the Offering, we will require additional financing through bank borrowings, debt or equity financing or otherwise to finance our planned operations. No assurance can be given that such alternate funding sources can be obtained or will provide sufficient, if any, financing for us. At this time, funds from operations are not sufficient to meet our anticipated financial requirements. Based on current plans, we believe that the net funds raised from sale of the common stock offered in our June 2000 private placement, together with current cash balances and funds from operations, will be sufficient to meet our operating needs for up to the next 18 months. The actual amount of funds that we will need to operate during this period will be determined by many factors, some of which are beyond our control. Therefore, we may need funds sooner than currently anticipated. Dependence on Relationships with Third Parties Our ability to successfully market and manufacture our products is dependent on relationships with both third party suppliers and customers. CCS Our success in marketing the CCS product is dependent on acceptance of our product by automotive OEMs and their seat suppliers. The CCS product is being offered as an optional feature on the 2000 model year Lincoln Navigator SUV and we are working with many other automotive OEMs and their seat suppliers in an effort to have the CCS product included in other models commencing with the 2001 model year and beyond. However, there is no assurance that automotive OEMs will accept our product. 7

We rely on various vendors and suppliers for the components of our products and procure these components through purchase orders, with no guaranteed supply arrangements. While we believe that there are a number of alternative sources for most of these components, certain components, including thermoelectric devices, are only available from a limited number of suppliers. The loss of any significant supplier, in the absence of a timely and satisfactory alternative arrangement, or an inability to obtain essential components on reasonable terms or at all, could materially adversely affect our business, operations and cash flows. Radar In light of the lengthy sales cycles to automotive OEMs and recent successes with our radar products in tests with trucks and heavy construction equipment, we have decided to focus our radar product in the truck and heavy construction equipment market rather than sales to automotive OEMs for passenger vehicles. We are currently working to obtain a development program with one of the world's leading suppliers of lighting systems for trucks and buses with a goal of integrating our radar product into its lighting systems for heavy trucks. However, we do not yet have a commitment from this company and, in any event, the success of this approach will depend in part on the other party's own competitive, marketing and strategic considerations, including the relative advantages of alternative products being developed and/or marketed by such party. Limited Manufacturing Experience To date, we have been engaged in only limited manufacturing in small quantities, and there can be no assurance that our efforts to establish our manufacturing operations for any of our products will not exceed estimated costs or take longer than expected or that other unanticipated problems will not arise which will materially adversely affect our operations, financial condition and/or business prospects. Automobile manufacturers demand on-time delivery of quality products, and some have required the payment of substantial financial penalties for failure to deliver components to their plants on a timely basis. Such penalties, as well as costs to avoid them, such as working overtime and overnight air freighting parts that normally are shipped by other less expensive means of transportation, could have a material adverse effect on our business and financial condition. Moreover, the inability to meet demand for our products on a timely basis would materially adversely affect our reputation and prospects. Limited Marketing Capabilities; Uncertainty of Market Acceptance Because of the sophisticated nature and early stage of development of our products, we will be required to educate potential customers and successfully demonstrate that the merits of our products justify the costs associated with such products. In certain cases, however, we will likely encounter resistance from customers reluctant to make the modifications necessary to incorporate our products into their products or production processes. In some instances, we may be required to rely on our distributors or other strategic partners to market our products. The success of any such relationship will depend in part on the other party's own competitive, marketing and strategic considerations, including the relative advantages of alternative products being developed and/or marketed by any such party. There can be no assurance that we will be able to market our products properly so as to generate meaningful product sales. Time Lag from Prototype to Commercial Sales The sales cycle in the automotive components industry is lengthy and can be as long as five years or more for products that must be designed into a vehicle, since some companies take that long to design and develop a car. Even when selling parts that are neither safety-critical nor highly integrated into the vehicle, there are still many stages that an automotive supply company must go through before achieving 8

commercial sales. The sales cycle is lengthy because an automobile manufacturer must develop a high degree of assurance that the products it buys will meet customer needs, interface as easily as possible with the other parts of a vehicle and with the automobile manufacturer's production and assembly process, and have minimal warranty, safety and service problems. As a result, from the time that an OEM develops a strong interest in our CCS product, it normally will take several years before our CCS is available to consumers in that OEM's vehicles. Radar Technology Still in Development Stage In contrast to CCS, which has begun commercial production, our AmeriGuard product is still in a developmental stage. As with all development projects, the Board of Directors will monitor its progress and future prospects carefully. If current testing with the New Mexico Highway and Transportation Department is unsuccessful or our efforts to obtain a development program with a supplier of truck lighting systems fail, the Board may reconsider its decision to continue development of the radar technology. Competition; Possible Obsolescence of Technology The automotive component industry is subject to intense competition. Virtually all of our competitors are substantially larger in size, have substantially greater financial, marketing and other resources than we do, and have more extensive experience and records of successful operations than we do. Competition extends to attracting and retaining qualified technical and marketing personnel. There can be no assurance that we will successfully differentiate our products from those of our competitors, that the marketplace will consider our current or proposed products to be superior or even comparable to those of its competitors, or that we can succeed in establishing relationships with automobile manufacturers. Furthermore, no assurance can be given that competitive pressures we face will not adversely affect our financial performance. Due to the rapid pace of technological change, as with any technology-based product, our products may even be rendered obsolete by future developments in the industry. Our competitive position would be adversely affected if we were unable to anticipate such future developments and obtain access to the new technology. Limited Protection of Patents and Proprietary Rights As of December 31, 1999, we owned three patents and had three patents pending. We were also licensees of sixteen patents. We believe that patents and proprietary rights have been and will continue to be very important in enabling us to compete. There can be no assurance that any new patents will be granted or that our or our licensors' patents and proprietary rights will not be challenged or circumvented or will provide us with any meaningful competitive advantages or that any pending patent applications will issue. Furthermore, there can be no assurance that others will not independently develop similar products or will not design around any patents that have been or may be issued to our licensors or us. Failure to obtain patents in certain foreign countries may materially adversely affect our ability to compete effectively in certain international markets. We are aware that an unrelated party filed a patent application in Japan on March 30, 1992 with respect to technology similar to our CCS technology. We recently became aware of a patent issued in Japan on November 10, 1998 and in the U.S. on July 20, 1999 regarding a temperature conditioner which is similar to one component of our CCS technology. These are in the name of affiliates of Honda Motor Co., Ltd. and, if upheld, could have a material adverse effect upon our intellectual property position. We believe, however, that there is substantial doubt that such patents will be upheld. 9

We hold current and future rights to licensed technology through licensing agreements requiring the payment of minimum royalties and must continue to comply with those licensing agreements. Failure to do so or loss of such agreements could materially and adversely affect our business. We also rely on trade secrets that we seek to protect, in part, through confidentiality and non-disclosure agreements with employees, customers, suppliers and other parties. There can be no assurance that these agreements will not be breached, that we would have adequate remedies for any such breach or that our trade secrets will not otherwise become known to or independently developed by competitors. To the extent that consultants, key employees or other third parties apply technological information independently developed by them or by others to our proposed projects, disputes may arise as to the proprietary rights to such information which may not be resolved in our favor. We may be involved from time to time in litigation to determine the enforceability, scope and validity of proprietary rights. Any such litigation could result in substantial cost to us and diversion of effort by our management and technical personnel. Additionally, with respect to licensed technology, there can be no assurance that the licensor of the technology will have the resources, financial or otherwise, or desire to defend against any challenges to the rights of such licensor to its patents. Exclusive License on Heated and Cooled Seats; Non-Exclusive License on Radar Technology In 1997, we negotiated with the licensor of the CCS technology an exclusive license for the manufacture and sale of licensed products for installation or use in automobiles, trucks, buses, vans and recreational vehicles. As part of the agreement, all intellectual property developed by us related to variable temperature seats is owned by us but such licensor will have the right to license our technology on a non-exclusive basis for use other than in automobiles, trucks, buses, vans and recreational vehicles. Our license from Lawrence Livermore National Laboratory (LLNL) for one type of radar technology became non-exclusive as of December 31, 1998. The lack of exclusivity means that we have reduced intellectual property protection for technology developed from this license and face possible competition from other companies which can acquire this license from LLNL. Special Factors Applicable to the Automotive Industry in General Automotive customers typically reserve the right to unilaterally cancel contracts completely or to require unilateral price reductions. Although they generally reimburse companies for actual out-of-pocket costs incurred with respect to the particular contract up to the point of cancellation, these reimbursements typically do not cover costs associated with acquiring general purpose assets such as facilities and capital equipment, and may be subject to negotiation and substantial delays in receipts by us. Any unilateral cancellation of, or price reduction with respect to, any contract that we may obtain could reduce or eliminate any financial benefits anticipated from such contract and could have a material adverse effect on our financial condition and results of operations. Dependence on Key Personnel Our success will depend to a large extent upon the continued contributions of Richard A. Weisbart, President and Chief Executive Officer and a director and Dr. Lon E. Bell, Director of Technology, a director and our founder. We have obtained key-person life insurance coverage in the amount of $2,000,000 on the life of Dr. Bell. The loss of the services of Dr. Bell, Mr. Weisbart or any of our executive personnel could materially adversely affect us. 10

Need to Retain Technical Personnel Our success will depend, in part, upon our ability to retain qualified engineering and other technical and marketing personnel. There is significant competition for technologically qualified personnel in the geographical area of our business and we may not be successful in recruiting or retaining sufficient qualified personnel. Reliance on Major Contractors We have in the past engaged certain outside contractors to perform product assembly and other production functions for us, and we anticipate that we may desire to engage contractors for such purposes in the future. We believe that there are a number of outside contractors that provide services of the kind that have been used by us in the past and that we may desire to use in the future. However, no assurance can be given that any such contractors would agree to work for us on terms acceptable to us or at all. Our inability to engage outside contractors on acceptable terms or at all would impair our ability to complete any development and/or manufacturing contracts for which outside contractors' services may be needed. Moreover, our reliance upon third party contractors for certain production functions will reduce our control over the manufacture of its products and will make us dependent in part upon such third parties to deliver its products in a timely manner, with satisfactory quality controls and on a competitive basis. Risk of International Operations We may engage contractors located in foreign countries. Accordingly, we will be subject to all of the risks inherent in international operations, including work stoppages, transportation delays and interruptions, political instability, foreign currency fluctuations, economic disruptions, the imposition of tariffs and import and export controls, changes in governmental policies and other factors which could have an adverse effect on our business. Potential Product Liability Our business will expose us to potential product liability risks which are inherent in the manufacturing, marketing and sale of automotive components. In particular, there may be substantial warranty and liability risks associated with our products. If available, product liability insurance generally is expensive. While we presently have $6,000,000 of product liability coverage with an additional $3,000,000 in product recall coverage, there can be no assurance that we will be able to obtain or maintain such insurance on acceptable terms with respect to other products we may develop, or that any insurance obtained will provide adequate protection against any potential liabilities. When and if high volume production begins, we expect to purchase additional insurance coverage. In the event of a successful claim against us, a lack or insufficiency of insurance coverage could have a material adverse effect on our business and operations. Risk of Foreign Sales Many of the world's largest automotive OEMs are located in foreign countries. Accordingly, our business is subject to many of the risks of international operations, including governmental controls, tariff restrictions, foreign currency fluctuations and currency control regulations. However, historically, substantially all of our sales to foreign countries have been denominated in U.S. dollars. As such, our historical net exposure to foreign currency fluctuations has not been material. No assurance can be given that future contracts will be denominated in U.S. dollars, however. 11

Risks Relating to Share Ownership - --------------------------------- Controlling Shareholders. On March 29, 1999, we entered into a Securities Purchase Agreement with Westar Capital II LLC ("Westar Capital II") and Big Beaver Investments LLC ("Big Beaver") (the "Preferred Stockholders") pursuant to which the Preferred Stockholders invested $9 million in Amerigon in return for 9,000 shares of Series A Preferred Stock (which are convertible into shares of our common stock at an initial conversion price of $1.675 per common share) and contingent warrants. The contingent warrants are exercisable only to the extent certain other warrants to purchase shares of our common stock are exercised, and then only to purchase a number of shares in proportion to the shares purchased by the exercise of such other warrants in an amount equal to the percentage interest in us that they had in us after the initial investment (on an as converted basis). In connection with this transaction, the Preferred Stockholders obtained the right to elect a majority of our directors as well as rights of first refusal on future financings and registration rights. In addition, based upon the terms of the Series A Preferred Stock at June 14, 2000, the Preferred Stockholders would have approximately 58.4% of our common equity (on an as converted basis, excluding options and warrants). As part of the VPA, we granted to Ford warrants exercisable for shares of our common stock. A warrant for the right to purchase 82,197 shares of our common stock at an exercise price of $2.75 per share was issued and fully vested on March 27, 2000. An additional warrant for 26,148 shares of our common stock was issued due to certain antidilution provisions triggered by the sale of 2.5 million common shares on June 14, 2000. Additional warrants will be granted and vested based upon purchases by Ford of a specified number of CCS units throughout the length of the VPA. The exercise prices of these additional warrants depend on when such warrants vest, with the exercise price increasing each year. If Ford does not achieve specific goals in any year, the VPA contains provisions for Ford to make up the shortfall in the next succeeding year. If Ford achieves all of the incentive levels required under the VPA, warrants will be granted and vested for an additional 1,300,140 shares of our common stock. The total number of shares subject to warrants which may become vested will be adjusted in certain circumstances for antidilution purposes, including an adjustment for equity issuances of up to $15 million on or before September 30, 2000, so that the percentage interest in us represented by the aggregate number of shares subject to warrants is not diluted by such issuances. Fluctuations in Quarterly Results; Small "Float" and Possible Volatility of Stock Price. Our quarterly operating results may fluctuate significantly in the future due to such factors as acceptance of our product by OEMs and consumers, timing of our product introductions and our competitors, availability and pricing of components from third parties, timing of orders, foreign currency exchange rates, technological changes and economic conditions generally. Broad market fluctuations in the stock markets can, obviously, adversely affect the market price of our common stock. In addition, failure to meet or exceed analysts' expectations of financial performance may result in immediate and significant price and volume fluctuations in our common stock. Without a significantly larger number of shares available for trading by the public, or public "float," our common stock will be less liquid than stocks with broader public ownership, and as a result, trading prices of the common stock may significantly fluctuate and certain institutional investors may be unwilling to invest in such a thinly traded security. Anti-Takeover Effects of Preferred Stock. The Series A Preferred Stock which is outstanding confers upon its holders the right to elect five of seven members of the Board of Directors. In addition, the Series A Preferred Stock will vote together with the shares of our common stock on any other matter submitted to shareholders. Based upon the 12

terms of the Series A Preferred Stock at June 14 2000, the Preferred Stockholders would have approximately 58.4% of our common equity (on an as converted basis, excluding options and warrants) and the ability to approve or prevent any subsequent change in control. In addition, our Board of Directors has the authority to issue up to 5,000,000 shares of preferred stock and to determine the price, rights, preferences and privileges of those shares without any further vote or action by the shareholders. The rights of the holders of our common stock will be subject to, and may be adversely affected by, the rights of the holders of any shares of preferred stock that may be issued in the future. The issuance of preferred stock, while providing desirable flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of making it more difficult for a third party to acquire a majority of our outstanding voting stock. Future Sales of Eligible Shares May Lower Price of Common Shares Sales of substantial amounts of our common stock into the public market could lower the stock market price. Due to the following, future sales of substantial amounts are possible: . As of the close of trading on June 23, 2000, we have 4,414,189 shares of our common stock outstanding, of which 1,914,189 are eligible for sale under Rule 144 of the Securities Act of 1933 (as amended). In addition, employees and directors (who are not deemed affiliates) hold options to buy 887,107 shares of our common stock, 843,940 of which are under the 1993 and 1997 Employee Stock Option Plans and 43,167 of which are non- plan options. The common stock to be issued upon exercise of these options, has been registered, and therefore, may be freely sold when issued. We also have outstanding warrants to buy 2,555,118 shares of our common stock. In addition, we have 1,653,520 contingent warrants, which are exercisable only if certain other warrants are exercised and only to the extent that such other warrants are exercised. Any shares registered will be eligible for resale. If these shares are not sold, they may be included in certain registration statements to be filed by us in the future. . We may issue options to purchase up to an additional 557,960 shares of our common stock under our 1993 and 1997 stock option plans. These options will be fully transferable when issued. . The holders of our Series A preferred stock may convert it into 5,373,134 shares of our common stock. These holders possess demand and piggyback registration rights. Future sales by them could depress the market price of our common stock. Lack of Dividends on Common Stock We have never paid any cash dividends on our common stock and do not anticipate paying dividends in the near future. USE OF PROCEEDS We will not receive any proceeds from the sale of the shares of common stock offered by the Selling Securityholders pursuant to this prospectus. 13

PLAN OF DISTRIBUTION The shares of common stock offered hereby may be sold by the Selling Securityholders or by their respective pledgees, donees, transferees or other successors in interest. Such sales may be made at fixed prices that may be changed, at market prices prevailing at the time of sale, at prices related to such prevailing market prices, or at negotiated prices. The shares may be sold by one or more of the following: 15

. one or more block trades in which a broker or dealer so engaged will attempt to sell all or a portion of the shares held by the Selling Securityholders as agent but may position and resell a portion of the block as principal to facilitate the transaction; . purchase by a broker or dealer as principal and resale by such broker or dealer for its account pursuant to this prospectus; . ordinary brokerage transactions and transactions in which the broker solicits purchasers; and . privately negotiated transactions between the Selling Securityholders and purchasers without a broker-dealer. The Selling Securityholders may effect such transactions by selling shares to or through broker dealers, and such broker-dealers will receive compensation in negotiated amounts in the form of discounts, concessions, commissions or fees from the Selling Securityholders and/or the purchasers of the shares for whom such broker-dealers may act as agent or to whom they sell as principal, or both (which compensation to a particular broker-dealer might be in excess of customary commissions). Such brokers or dealers or other participating brokers or dealers and the Selling Securityholders may be deemed to be "underwriters" within the meaning of the Securities Act, in connection with such sales. Except for customary selling commissions in ordinary brokerage transactions, any such underwriter or agent will be identified, and any compensation paid to such persons will be described, in a prospectus supplement. In addition, any securities covered by this prospectus that qualify for sale pursuant to Rule 144 might be sold under Rule 144 rather than pursuant to this prospectus.

PART II Item 14. Other Expenses of Issuance and Distribution The expenses in connection with the registration of shares of the Selling Securityholders will be borne by the Company and are estimated as follows: Commission registration fee............................ $ 851,250 Printing and engraving................................. 6,521 Accounting fees and expenses........................... 40,000 Legal fees and expenses................................ 220,000 Miscellaneous expenses................................. 31,000 Total.................................................. $1,148,771 Item 15. Indemnification Of Directors and Officers The Company's Articles of Incorporation limit the liability of its directors. As permitted by the California General Corporation Law, directors will not be liable to the Company for monetary damages arising from a breach of their fiduciary duty as directors in certain circumstances. Such limitation does not affect liability for any breach of a director's duty to the Company or its shareholders (i) with respect to approval by the director of any transaction from which he derives an improper personal benefit, (ii) with respect to acts or omissions involving an absence of good faith, that he believes to be contrary to the best interests of the Company or its shareholders, that involve intentional misconduct or a knowing and culpable violation of law, that constitute an unexcused pattern of inattention that amounts to an abdication of his duty to the Company or its shareholders, or that show a reckless disregard for his duty to the Company or its shareholders in circumstances in which he was or should have been aware, in the ordinary course of performing his duties, of a risk of serious injury to the Company or its shareholders, or (iii) based on transactions between the Company and its directors or another corporation with interrelated directors or on improper distributions, loans or guarantees under applicable sections of the California General Corporation Law. Such limitation of liability also does not affect the availability of equitable remedies such as injunctive relief or rescission. The Company's Bylaws provide that the Company shall indemnify its directors and officers to the full extent permitted by California law, including circumstances in which indemnification is otherwise discretionary under California law, and the Company has entered into indemnity agreements with its directors and officers providing such indemnity. Item 16. Exhibits See attached Exhibit Index that follows the signature page. Item 17. Undertakings The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high and of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement. (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement. Provided, however, that paragraphs (1)(i) and (1)(ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") that are incorporated by reference in the Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (4) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (5) That, for purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective. (6) That, for the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a

new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (7) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions described in Item 6 above, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Irwindale, State of California, on June 29, 2000.

Authorization Of Sale Of The Securities. The Company has authorized the sale and issuance of 2,500,000 shares of its common stock, no par value (the "Common Shares"), as described in the Private Placement Memorandum dated April 2000 (as supplemented on May 30, 2000, the "Memorandum").

EXHIBIT 1.2 ESCROW AGREEMENT Amerigon, Inc., a California corporation ("Issuer"), California Bank and Trust ("Escrow Agent")and, Roth Capital Partners, Inc. ("Placement Agent"), mutually agree as follows: 1. Purpose. The purpose of this Agreement is to provide an arrangement that will ensure that proceeds from the sale of the Issuer's Class A Common Stock Shares (the "Common Shares")under its offering pursuant to Regulation D under the Rules and Regulations of the Securities Act of 1933, as amended (the "Offering"), will not be disbursed until at least the Escrow Amount (as defined below)has been received from the sale of the Common Shares and is available to the Issuer, and if such amount has not been received by the date specified below, that such funds as have been received for the Common Shares will be returned to the proposed purchasers and the conditional securities transactions terminated. 2. Escrow Amount. The minimum amount which must be deposited with the Escrow Agent before any delivery to the Issuer and the Placement Agent of proceeds from the sale of the Common Shares shall be $25,000 and is called the "Escrow Amount." Additional amounts above the Escrow Amount shall also be disbursed in accordance with Section 11. 3. Appointment. The Issuer hereby appoints the Escrow Agent to serve as Escrow Agent for the purposes set forth herein and the Escrow Agent hereby accepts the appointment. The Placement Agent hereby agrees to such appointment. 4. Delivery of Proceeds. The Placement Agent shall promptly deliver, or cause to be wired or deposited, by noon of the business day following receipt, to the Escrow Agent in accordance with Rule 15c2-4 under the Securities Exchange Act of 1934, as amended, all proceeds from the sale of the Issuer's Common Shares under the Offering. In no event shall the Escrow Agent accept delivery of any proceeds, whether from the Placement Agent or any other person or entity, after the Escrow Agent has been notified by the Issuer or the Placement Agent to stop accepting delivery of proceeds. 5. Check Collection Procedure; Rejected Purchasers. The Escrow Agent is hereby authorized to forward any and all checks received for collection and, upon collection of proceeds of each such check, deposit the collected proceeds in the Escrow Account. "Collection" shall mean the normal process by which a bank clears checks and collects funds thereon. Any check returned unpaid to the Escrow Agent shall be held by the Escrow Agent pending instructions from the Issuer and the Placement Agent. In such cases, the Escrow Agent will promptly notify the Issuer and the Placement Agent of such return. Prior to disbursement of proceeds under Section 11, Escrow Agent shall charge back any returned item against the escrow account (defined below). If the Issuer or Placement Agent rejects any or all offers to purchase shares of the Common Shares and delivers written instruction of such rejection to the Escrow Agent, (i)if the Escrow Agent has already received such funds by wire transfer or collected a proposed purchaser's funds, the Escrow Agent shall promptly issue a refund check to each rejected proposed purchaser in an amount equal to such rejected proposed purchaser's deposit, without interest thereon, (ii) if the Escrow Agent has not yet collected funds but has submitted a rejected proposed purchaser's check for

collection, the Escrow Agent shall promptly issue a check in the amount of the proposed purchaser's check to the rejected proposed purchaser after clearance of such funds, and (iii)if the Escrow Agent has not yet submitted a rejected proposed purchaser's check for collection, the Escrow Agent shall promptly remit the rejected proposed purchaser's check directly to the rejected proposed purchaser. The Placement Agent must supply information to the Escrow Agent, in accordance with Section 12 sufficient for the Escrow Agent to perform its duties here under. 6. Separate Account. All moneys delivered to or collected by the Escrow Agent pursuant to this Agreement shall be deposited immediately by the Escrow Agent in a separate interest bearing account designated substantially as follows: "Amerigon, Inc. Escrow Account" (hereinafter sometimes referred to as "Escrow Account"). The Escrow Agent will provide its standard account statements to the Issuer and Placement Agent at terms mutually acceptable to all parties. 7. Nature of Escrow Account. The Escrow account will be an interest bearing deposit account. 8. Inspection. The parties agree that all records relating to transactions made pursuant to this Agreement and the Escrow Account shall be available, at all reasonable times, for inspection, examination and reproduction by the securities authorities in any state in which this Offering is registered, such person's delegate or representative, or any party hereto, or any representative of any of the parties hereto, and such persons are authorized to examine and audit the Escrow Account pursuant hereto and the Escrow Agent hereby is expressly authorized and directed to permit such examination and audit. 9. Ownership of Fund. Until the Escrow Amount is disbursed as provided in paragraph 11 hereof, all amounts deposited in the Escrow Account shall be considered the property of the various proposed purchasers of the Common Shares proportioned to the amount contributed by each proposed purchaser; provided, however, that no purchaser shall have the right to withdraw, revoke or rescind its deposit without the prior written consent of the Issuer and the Placement Agent. The proceeds from the sale of such shares of Common Shares pursuant to the Offering shall not become the property or assets of the Issuer or Placement Agent, nor subject to their debts or obligations, unless and until the Escrow Amount has been disbursed to them. 10. Term. If the Escrow Amount is not deposited and collected on or before September 1, 2000, (which period may be extended for periods in the aggregate not to exceed an additional 60 days upon mutual written consent of the Issuer and the Placement Agent), the Escrow Agent shall comply with instructions from each proposed purchaser for the return to such proposed purchaser of the amount of money paid and deposited by such proposed purchaser into the Escrow Account, without interest thereon, and the disbursement shall be the property of such purchaser, free and clear of any and all claims of the parties hereto (other than returned check claims, if any, by the Escrow Agent)or of any of their creditors. At such time as the Escrow Amount and any additional funds deposited are either disbursed in accordance with paragraph 11 hereof or returned to the purchasers, the Escrow Agent shall be completely discharged and released of any and all further liabilities and obligations hereunder. 2

11. Disbursement of Funds. After the Escrow Amount has been deposited and collected by the Escrow Agent, and after the conditions set forth in the last sentence of this paragraph 11 have been satisfied, the Escrow Agent shall promptly distribute, in immediately available funds, any funds and any accumulated interest in the Escrow Account in accordance with written instructions delivered to the Escrow Agent signed by the Issuer and the Placement Agent. The Issuer and the Placement Agent agree that the Escrow Agent needs no further written or other authority to distribute such funds. The Escrow Agent shall disburse such funds by delivery of a cashier's check or by wire transfer, as instructed by the Issuer and Placement Agent, respectively. The Issuer and Placement Agent agree that no certificates evidencing securities comprising the shares of Common Shares which were purchased (other than confirmations of sale)shall be issued except simultaneously with the release of the funds from the Escrow Account to the Issuer and Placement Agent; provided, however, that the Escrow Agent has no duty to verify the foregoing. Funds shall not be released by the Escrow Agent to the Issuer or Placement Agent unless (i)the Placement Agent acknowledges in writing to the Escrow Agent that either it or the purchasers have received, or the Placement Agent has made arrangements satisfactory to it for it or the purchasers to receive stock certificates evidencing the securities comprising the shares of Common Shares purchased with the amounts deposited in the Escrow Account, (ii) the Placement Agent acknowledges in writing to the Escrow Agent that each purchaser has entered into a subscription agreement acceptable to the Placement Agent and Issuer and (iii) the Placement Agent has received a certificate signed as of the date of each closing by the executive officers of the Company named therein in a form reasonable acceptable to the Placement Agent. 12. Escrow Agent's Responsibility. The parties agree to provide to the Escrow Agent all information necessary to facilitate the administration of this Agreement and the Escrow Agent may rely upon any representation so made. Nothing contained in this Agreement shall constitute the Escrow Agent as trustee for any party hereto or impose on the Escrow Agent any duties or obligations other than those for which there is an express provision herein. Except as provided herein, the Escrow Agent shall have no responsibility or liability for delivery of the Escrow Amount. For all purposes connected herewith the Escrow Agent shall be entitled to assume that the parties hereto are exclusively entitled to their share of the Escrow Amount in accordance with this Agreement and are fully authorized and empowered, without affecting the rights of any third parties, to appoint the Escrow Agent as the Escrow Agent in accordance with the terms and provisions hereof. The Escrow Agent shall be obliged to render statements of account only with respect to the Escrow Amount deposited to the parties referred to herein and the Escrow Agent shall not be under any obligation to render any statements of account to any third parties unless the Escrow Agent so consents in writing. The Issuer will not make any reference to California Bank and Trust in connection with the Offering except with respect to its role as Escrow Agent hereunder; and in no event will the Issuer state or imply that Escrow Agent has investigated or endorsed the Offering in any manner whatsoever. 13. Limitations on Liability. It is understood that the Escrow Agent shall incur no liability, except for acts of gross negligence or willful misconduct, and be under no obligation to take any steps or action to assure that any funds are actually received by the Escrow Agent. None of the provisions hereof shall be construed so as to require the Escrow Agent to expend or risk any of its own funds or otherwise incur any liability in the performance of it duties under this Agreement and it shall be under no obligation to make any payment before all times for returns have expired and except out of the funds received, after deduction of its fees and expenses. The Escrow Agent shall 3

incur no liability if it becomes illegal or impossible to carry out any of the provisions herein. The Escrow Agent shall not be required to take or be bound by notice of default of any person, or to take any action with respect to such default involving any expense or liability, unless written notice of such default is given to the Escrow Agent by the undersigned or any of them, and unless the Escrow Agent is indemnified in a manner satisfactory to it against such expense or liability. The Escrow Agent shall not be liable to any party hereto in acting upon any written notice, request, waiver, consent, receipt or other paper or document believed by the Escrow Agent to be signed by the proper party or parties. The Escrow Agent will be entitled to treat as genuine and as the document it purports to be any letter, paper, telex or other document furnished or caused to be furnished to the Escrow Agent. The Escrow Agent shall have no liability with respect to any good faith action taken or allowed by it hereunder, except for acts of gross negligence or willful misconduct. The Escrow Agent shall not be liable for any error or judgment or for any act done or step taken or omitted by it in good faith or for any mistake or fact or law, except for acts of gross negligence or willful misconduct, or for anything which it may do or refrain from doing in connection herewith, and the Escrow Agent shall have no duties to anyone except those signing this Agreement. The Escrow Agent may consult with legal counsel in the event of any dispute or questions as the interpretation or construction of this Agreement or the Escrow Agent's duties hereunder. In addition, the Escrow Agent shall incur no liability and shall be fully protected in acting in accordance with the opinion and instructions of counsel, except for acts of gross negligence or willful misconduct. In the event of any disagreement between the undersigned or any person or persons named in this Agreement, and any other person, resulting in adverse claims and demands being made in connection with or for any money involved herein or effected hereby, the Escrow Agent shall be entitled at its option to refuse to comply with any such claims or demands, so long as such disagreement shall continue, and in so doing the Escrow Agent shall not be or become liable for damages or interest to the undersigned or any of them, or to any person named in this Agreement, for its refusal to comply with such conflicting or adverse demands; and the Escrow Agent shall be entitled to continue so to refrain and refrain and refuse so to act until (i) the rights of the adverse claimants have been finally adjudicated in a court or by arbitration as set forth below assuming and having jurisdiction of the parties and the money involved herein and affected hereby; or (ii) all differences have been adjudicated by agreement and the Escrow Agent has been notified thereof in writing by all of the persons interested. 14. Resignation of the Escrow Agent. The Escrow Agent reserves the right to resign as the Escrow Agent at any time by giving thirty (30) business days written notice thereof to all parties at the last known address.
