     Re: Letter of Intent and Firm Offer to Form Proposed New Company
         ------------------------------------------------------------

Dear Matsuzaki-San:

     This letter sets forth a firm proposal from Amerigon Incorporated, a 
California corporation ("Amerigon"), to Yazaki Corp., a Japanese company 
("Yazaki"), to form a new company in conjunction with Technology Strategies 
and Alliances, a California corporation ("TSA"). After this letter is 
initially executed by both parties, this letter will have no binding effect 
and will function as a letter of intent. Amerigon will then rapidly prepare a 
draft Definitive Agreement for the formation of the New Company. Within three 
business days of receiving this Draft Definitive Agreement, Yazaki shall 
consider signing Addendum A to this letter. If Yazaki elects not to sign and 
return Addendum A within three days, this letter shall automatically expire 
and be withdrawn. Once Addendum A is signed by Yazaki and countersigned and 
returned by Amerigon, this letter of intent will become a binding agreement 
on both parties.

     1. FUNDING FOR THE EXCLUSIVE RIGHTS TO NEGOTIATE WITH AMERIGON; 
        DEFINITIVE AGREEMENT.

         a. Within 7 Business days, 1 month, and 2 months, respectively, 
   after Yazaki's and Amerigon's countersignature of Addendum A of this 
   letter, Yazaki shall pay to Amerigon $300,000, $350,000 and $350,000 of 
   funding in consideration for Yazaki's exclusive rights to negotiate for a 
   period of three months with Amerigon to acquire a stock or equity interest 
   in the IVS project (as defined below) for a period of three months by wire 
   transfer of immediately available funds. The parties shall negotiate in 
   good faith during the three-month period following the effective date of 
   Addendum A of this letter to arrive at a definitive agreement for the 
   consummation of the transactions contemplated by this letter, with the 
   parties making a good faith effort to complete the negotiations within 30 
   to 45 days, in order to take advantage of market opportunities.



         b. Until the consummation of the transactions contemplated by this 
   letter, the expiration of such three month period or the time at which 
   Yazaki shall determine not to go forward with the transactions 
   contemplated by this letter, whichever is earlier, Amerigon shall apply 
   funds from Yazaki's funding only for the research and development of the 
   IVS business, and shall account to Yazaki in a mutually agreed manner on 
   the use of these funds to verify that they are used only for this 
   specified purpose. With the delivery of the draft definitive agreement, 
   Amerigon shall provide Yazaki a preliminary 3 month budget for the 
   funding, detailing the expenditures on people, equipment, outside 
   contracts, leases and other expenses. During the three month period, 
   Amerigon will report monthly with documentation of expenditures on the 
   actual expenditures compared to this budget, and will inform Yazaki of any 
   required changes in the budget prior to receiving the next funding 
   payment. The $1,000,000 to be provided by Yazaki to Amerigon during the 
   above three month period shall be spent on direct costs and itemized 
   indirect costs with the understanding that the goal will be to minimize 
   the indirect costs.

         c. In the event that at the end of such three month period no 
   definitive agreement has been executed and delivered, Amerigon shall be 
   entitled to retain the entire amount of the funding. In the event that at 
   any time during such three month period Yazaki shall notify Amerigon that 
   Yazaki will not go forward with the transactions contemplated by this 
   letter, Amerigon shall be entitled to retain the portion of the funding 
   that Amerigon has received to date.

         d. In the event that a definitive agreement is reached during such 
   three month period, and the transactions contemplated by this letter are 
   eventually consummated, the intellectual and tangible property developed 
   or acquired with Yazaki's funding with be fully transferred and assigned 
   to SVE (as defined below), which shall be its sole owner in fee title. In 
   the event that no definitive agreement is reached during this period 
   Amerigon shall retain full ownership and control of all the intellectual 
   and tangible property related to IVS developed with the funding.

         e. Amerigon will return 100% of all funding received if Yazaki 
   decides not to consummate the transaction envisioned by this letter ONLY 
   in the event of either of one or more of the following three causes:

         (1) Yazaki found while undertaking due diligence during such three 
             month period that Amerigon had either: (1) materially 
             misrepresented the ownership of its technology or the validity 
             thereof; (2) materially misrepresented its contract and license 
             rights relating to four companies: the Settlement and License 
             Agreement with Audio Navigation Systems LLC, and the license 
             agreements with Navigation Technologies, ETAK and Lernout & 
             Hauspie Speech Products; or (3) that these same contracts do

                                         2



             not remain valid and in force. In determining whether Amerigon 
             has made any such material misrepresentations, Yazaki shall rely 
             solely on: (i) whether Amerigon has provided true, correct and 
             complete copies of the 4 contracts and any relevant 
             correspondence that may modify or affect the contracts with 
             these companies; and (ii) written communications from Joshua 
             Newman of Amerigon that have been or are made to Yazaki to help 
             explain these contracts. Prior to sending the draft definitive 
             agreement to Yazaki, Joshua Newman will forward an official copy 
             of the 4 licenses, any relevant correspondence that may modify 
             or affect the contracts, and previous written communications 
             from Amerigon that Yazaki may relay on to help explain these 
             contracts.

         (2) Yazaki found that Amerigon, as of the date of signing the 
             definitive agreement has any threatened or pending lawsuits or 
             disputes that will materially diminish the value of the IVS 
             business, except that Yazaki understands that Amerigon is in 
             arrears in paying advance royalties due Lernout & Hauspie Speech 
             Products, per a letter received from them dated February 4, 1997 
             (a copy of which was faxed to Yazaki) and that Amerigon is in 
             breach of this license, making it subject to immediate 
             cancellation. In recognition of this, Addendum A will not be 
             effective until Amerigon countersigns it, representing that it 
             has paid $75,000 in overdue advance royalties to Lernout & 
             Hauspie from Amerigon's own funds, separate from the funding 
             that Yazaki will provide for the IVS program. This $75,000 
             payment, combined with a prior $30,000 payment, constitutes a 
             credit that can be used to reduce future royalty obligations, 
             and is one of the assets that Amerigon will assign to SVE as 
             part of this contemplated transaction. SVE will be responsible 
             for the outstanding $95,000 payment to Lernout & Hauspie out of 
             the $200,000 contract concluded between Amerigon and Lernout & 
             Hauspie.

         (3) Amerigon has failed to obtain the employment services of (i) 
             Mr. Bob Diller and (ii) Messrs. Mark Eggleston, Mark Ross and 
             James Douma or their equivalent technical staff for the SVE. It 
             is understood that the business plan will encompass the salary, 
             benefits and company location, reasonable to both the employees 
             and SVE, to be provided to the above four (4) employees 
             including the stock option offers.

         f. As an alternative to the payment schedule contemplated by 1.a 
   above, the parties may enter into a separate agreement pursuant to which 
   Yazaki shall deposit $1,000,000 in a Yazaki account in Japan during the 
   three month period. The funds in the account shall be distributed to

                                     3



   Amerigon upon the earlier of (i) the closing of the transactions 
   contemplated herein or (ii) the end of the three month period, unless 
   Amerigon has declared bankruptcy during the three month period.

         g. If no definitive agreement is reached during the three month 
   period, Yazaki is not obligated to pay Amerigon any additional moneys 
   except those contemplated in this agreement, including no obligation to 
   pay Amerigon any damages or other type of relief.

         2. BASIC PLAN. On the terms and conditions to be set forth in a 
definitive agreement, Amerigon and Yazaki will establish a new company 
(tentatively named "Smart Vehicle Electronics," or "SVE") that would carry 
forward Amerigon's Interactive Voice Systems ("IVS") products business. SVE 
will focus on selling only to the automotive industry aftermarket. Yazaki is 
to provide SVE's financial and other resources, and to receive a specified 
equity interest in, and managerial oversight of, SVE, as well as certain 
technology transfer, exclusive licenses and other rights. The exact amount 
and type of resources that Yazaki will provide will be determined during the 
three month period through joint business planning between Amerigon, Yazaki 
and TSA, with the understanding that necessary funds will be provided by 
Yazaki to pursue the aftermarket product and OEM strategy. The mutual 
agreement on SVE resources will be included in the definitive agreement. 
Although the exact structure of the transactions by which SVE is to be formed 
will be negotiated as part of the definitive agreement, it is generally 
contemplated that (a) in exchange for a specified equity interest in SVE and 
cash, Amerigon will transfer to SVE or Yazaki in a merger or similar 
transaction an equity interest in an entity which owns all of Amerigon's 
assets relating to the IVS project including all IVS technology, transferable 
licenses, designs know-how and equipment that is unique to the IVS project 
such as computers, sound studio and production and test equipment and IVS 
inventory), and (b) that upon completion of the transactions, all such assets 
relating to the IVS will be owned by SVE, and that the stock or equity 
interests in SVE will be owned by Yazaki and Amerigon. Amerigon will not 
transfer any IVS liabilities (such as accounts payable or product warranties) 
to SVE with the exceptions of the obligation to respond to help desk 
inquiries from current end-user purchasers of the IVS and the obligation to 
complete the AISIN Seiki and Real-Time Traffic Data contracts on the 
condition that sufficient engineers necessary to complete the above contracts 
are transferred to SVE (SVE will collect any cash payments received under 
these contracts from revenues that accrue after the effective date of 
Addendum A). It is also contemplated that all of Amerigon's professional 
personnel devoted to the IVS business would be employed by SVE.

         3. GENERAL INTENT. It is the general intent of the parties, that the 
establishment of SVE will result in an on-going, cooperative enterprise that 
will:

            a. Strengthen Yazaki's core automotive business;

            b. Provide a technology transfer to Yazaki that will enable 
   Yazaki to diversify into new business beyond its current strategic 
   directions; and

            c. Insure SVE's success and enable it to grow into a substantial 
   business by exploiting Amerigon's IVS technology and by developing new 
   technologies for the future.

                                      4

               (1) Amerigon will transfer in a merger or other transaction,

business.

               (2) Amerigon will receive 4,062,000 shares in SVE with an

               (3) Amerigon will receive from SVE U.S. $2 million in cash 
from SVE. The timing and terms of payment of such amount is to be negotiated 
among the parties and specified in a definitive agreement. The first U.S. $1 
million in cash from SVE to Amerigon will be paid upon within 30 days after 
SVE's receipt of the certificate of incorporation. The second U.S. $1 million 
will be paid by SVE to Amerigon twelve (12) months after the execution of the 
definitive agreement.

            b. YAZAKI

pursue SVE's business plan, per paragraph 2.

and manufacture all SVE products to OEMs world-wide, whether to automotive or

required "pass-through" royalties, including, but not limited to, those for 
maps, speech and voice licenses) world-wide licenses to SVE's "hands free, 
eyes free" technology for application to products that are outside the scope 
of SVE's strategic plan, and shall be entitled to apply these technologies to 
new Yazaki products.

               (5) Yazaki may manufacture product for SVE per mutual 
agreement between SVE and Yazaki, provided Yazaki is competitive.

                                      5



         5. RESERVED EQUITY. 5,937,000 shares in SVE, representing 23.75% 
(fully diluted) of SVE's total equity, will be reserved for key officers, 
employees, "working" directors and TSA (see Section 8 below) through a stock 
option plan. Such options will be awarded as incentive to key employees, 
"working" directors and TSA (as contemplated by Section 8 below). The details 
of the plan and the participants therein will be determined by the SVE CEO, 
subject to the approval of the SVE Board of Directors.

         6. (a) Both Yazaki and Amerigon shall not transfer their shares of 
SVE to any party within the first seven (7) years except through appropriate 
mergers or acquisitions of Amerigon's stock provided always that in the event 
of such mergers or acquisitions, Yazaki shall have the option to purchase all 
of Amerigon's shares of SVE for whichever is the lower price between (i) 
$4,000,000 or (ii) the price determined in accordance with 6(a)ii) below. 
After the above seven (7) years have elapsed, Amerigon shall have the right 
to liquidate its stocks through the following two mechanisms;

             i) The sale of Amerigon's shares in SVE to any third party which 
does not compete with or harm the interests of SVE provided always that 
Yazaki shall have the first refusal right to purchase the above shares on the 
same terms and conditions extended to the said third party.

            ii) The sale (put option) of Amerigon's shares in SVE to Yazaki 
based on the average of the two lowest figures to be calculated by three 
appraisers consisting of one appraiser selected by Yazaki, one appraiser 
selected by Amerigon and a final appraiser to be selected by the two 
appraisers selected by Yazaki and Amerigon respectively. The above mentioned 
appraisers should be selected among international, reputable investment banks 
or accounting firms.

            (b) In the event of an IPO of SVE, Amerigon shall have the right 
to register its shares for liquidation purposes and Amerigon's rights 
mentioned above in 6(a)i) and ii) shall be forfeited.

         7. GOVERNANCE.

            a. SVE's Board of Directors shall initially include five seats. 
It is the intent that Yazaki, through its Board majority, shall exercise full 
operating control over SVE while appropriately protecting the rights of 
minority shareholders and stock option holders. To help protect these rights, 
the definitive agreement will specify Board actions that require a consensus 
(80%) vote which will be limited to i) changes in by-laws and articles of 
incorporation which will be consistent with this letter, including this 
section, ii) actions related to mergers with Yazaki's affiliates or 
substantial assets sales and licenses to Yazaki's affiliates either of which 
may be detrimental to the purposes of SVE's activities in the aftermarket 
business and iii) changes in the number of Board of Directors. All other Board 
actions (such as approval of stock options, appointment or removal of 
officers, approval of financial reports, audit, increase of capital and 
distribution of dividends) will require only a simple majority vote.

                                      6



            b. Amerigon shall be entitled to one seat on the SVE Board of 
Directors.

            c. Yazaki will be entitled to three seats on the SVE Board of 
Directors. Futhermore, should the size of the Board be increased, the number 
of seats to which Yazaki and Amerigon will be entitled will remain in 
proportion to their equity ownership in SVE.

            d. The SVE CEO will be a member of the Board of Directors.

            e. In the event that SVE wishes to increase its capital, SVE 
            shall give preemptive rights to subscribe newly issued shares to 
            each shareholders in accordance with its percentage shares 
            provided always that if any party declines to participate in the 
            increase of capital, the other party shall be permitted to 
            increase the capital on its own and the percentage shares of the 
            declining party will be diluted accordingly.

            8. MATTERS RELATING-TO-TSA-

            a. TSA partner Bob O. Evans will be the initial CEO of SVE. It is 
intended that Mr. Evans will remain in this capacity and work in Monrovia, 
California until approximately Dec. 31, 1997, at which time a successor CEO 
is expected to be in place. Thereafter, Mr. Evans will serve SVE at the 
pleasure of the Board of Directors.

            b. In recognition of the foregoing services, TSA will receive 
options to purchase 624,975 shares in SVE, representing a 2.5% (fully diluted) 
equity interest in SVE, pursuant to and on the same terms and conditions 
afforded to other participants in the stock option plan referred to in 
Section 5 above.

            9. DEFINITIVE AGREEMENT; APPROVALS AND CONSENTS. The definitive 
agreement will contain terms, conditions, representations, warranties and 
covenants customary and appropriate for a transaction of the type 
contemplated hereby. The agreement will contemplate that the parties will 
need to obtain all required regulatory approvals and third party consents. 
Furthermore, the definitive agreement shall be entirely consistent and 
conform with this letter of intent and such definitive agreement shall not 
contain any provisions which will unreasonably work against the interests of 
Yazaki.

           10. CONFIDENTIALITY. The parties have previously entered into a 
binding confidentiality agreement which shall remain in full force and effect.

           11. PUBLICITY. The parties shall coordinate all publicity, if any, 
relating to this proposal. No party shall issue any press release, publicity 
statement or other public notice relating to the new company or this letter 
without the prior consent of the other party unless required to do so under 
applicable securities laws. The parties shall consult with one another as to 
the content of any communication to their respective shareholders or any 
governmental authority, relating to the new company.

                                      7



           12. ENFORCEABILITY; SEVERABILITY. This letter is intended to be a 
firm offer to form SVE, enforceable in accordance with its terms. If any 
provision of this agreement shall be held invalid, illegal or unenforceable, 
the validity, legality and enforceability of the remaining provisions hereof 
shall not in any way be affected or impaired thereby. Any provision of this 
agreement held invalid or unenforceable only in part or degree will remain in 
full force and effect to the extent not held invalid or unenforceable.

           13. GOVERNING LAW. This letter shall be governed by and construed 
in accordance with the laws of the State of California, without regard to 
doctrines of conflicts of laws.

                                     8



          If this letter is satisfactory to you as a proposal to form SVE, 
please so signify by executing this letter on behalf of Yazaki where 
indicated below and returning it to me.

          We look forward to working with you to consummate the formation of 
SVE and to making it a success.

other party during the period beginning from the signing of this letter of 
intent until the earlier of the signing of the definitive agreement; when 
Yazaki stops payment mentioned in Section 1(a), or the three months after the 
countersigning of this Addendum A.
