AMERIGON INCORPORATED NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS Note 1 - The Company Amerigon Incorporated (the "Company"), incorporated in California in April 1991, is a developer, marketer and manufacturer of proprietary, high technology electronic components and systems for sale to car and truck original equipment manufacturers ("OEMs"). The Company is currently focusing its efforts on the introduction of its Climate Control Seat(TM) ("CCS(TM)"), which provides both heating and cooling to seat occupants, and the development of the next generation CCS device. Note 2 - Basis of Presentation and Summary of Certain Accounting Policies The accompanying condensed consolidated financial statements as of June 30, 2001 have been prepared by the Company without audit. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) necessary for fair presentation have been included. The consolidated results of operations for the six-month period ended June 30, 2001 are not necessarily indicative of the operating results for the full year. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in the Company's Form 10-K for the year ended December 31, 2000. Certain amounts have been reclassified from the prior year Form 10-Q to conform to current period presentation. Note 3 - Going Concern The Company has suffered recurring losses and negative cash flows from operations since inception and has a significant accumulated deficit. The Company expects to incur losses for the next one to two years as current sales volumes are not sufficient to cover the Company's fixed manufacturing, overhead and operating costs. Sufficient volume will not be reached in the near term, as automotive industry development timing tends to be relatively long. Even with the shipments of volume production for the Lincoln Navigator SUV, Lincoln Blackwood, Lexus LS 430 and Toyota Celsior, the revenue generated from the initial orders will not be sufficient to meet the Company's operating needs. There can be no assurance that profitability can be achieved in the future. Although the Company has begun production on its CCS product, larger orders for the CCS product will require significant expenses for tooling and to set up manufacturing and/or assembly processes. The Company also expects to require significant capital to fund other near-term production engineering and manufacturing, as well as research and development and marketing of these products. Future financing will be required and there can be no assurance that additional financing will be available in the future or that it will be available on favorable terms. These conditions raise substantial doubt about the Company's ability to continue as a going concern. (6)

Note 3 - Going Concern (cont.) In March 2001, the Company entered into a Manufacturing and Supply Agreement and a Subscription Agreement with Ferrotec Corporation, a Tokyo based manufacturer (see Note 8). Ferrotec paid to the Company $2,000,000 and $1,000,000 in April 2001 in accordance with the Manufacturing and Supply Agreement and the Subscription Agreement, respectively. The Company is obligated, under the BSST option agreement (see Note 4), to pay an additional $1,090,000, in installment payments, to BSST by February 28, 2002. Management will need to seek additional sources of permanent equity or long-term financing to fund its operations. The outcome of such efforts to obtain additional financing cannot be assured. Note 4 - Investment in BSST / Restricted Cash Dr. Lon Bell, the founder of Amerigon, established BSST as a Delaware limited liability company in August 2000. BSST is engaged in a research and development effort to improve the efficiency of thermoelectric devices. The objective of these efforts is to expand the applications of thermoelectric devices to automotive and non-automotive applications, that could include for example temperature control and power generation. In September 2000, the Company entered into an option agreement with BSST to purchase 2,000 Series A Preferred Shares, which represents a 90% interest in BSST, for $2,000,000. At June 30, 2001, the Company has paid to BSST $910,000 and is required to pay an additional $1,090,000 in installments of no more than $400,000 in any three month period, beginning August 31, 2001. No accrual has been recorded for this commitment. This acquisition was accounted for by the purchase method of accounting. The Preferred Shares give the Company a 90% voting interest and a 90% interest in the results of operations of BSST. At the time of the exercise of its option, the Company recorded a charge to research and development costs of $357,000 representing the excess of its investment to date in BSST over the proportional underlying net assets of BSST. The condensed consolidated financial statements at June 30, 2001 reflect the consolidated financial position and consolidated operating results of the Company and, since June 1, 2001, BSST. Intercompany accounts have been eliminated in consolidation. The 10% of BSST not owned by the Company is reflected as minority interest. Had the acquisition of BSST occurred as of January 1, 2001, the pro forma consolidated net loss for the six months ended June 30, 2001 would not have been significantly different. Restricted cash represents cash that is available exclusively to BSST. Note 5 - Inventory Details of inventory by category, in thousands: June 30, December 31, 2001 2000 --------------- ------------------ Raw material $ 943 $ 1,118 Work in process 51 76 Finished goods 407 452 --------------- ------------------ Total inventory 1,401 1,646 Less inventory reserve (168) (168) --------------- ------------------ Net inventory $ 1,233 $ 1,478 =============== ================== (7)

Note 6 - Net Loss per Share The Company's net loss per share calculations are based upon the weighted average number of shares of Common Stock outstanding. Because their effects are anti-dilutive, net loss per share for the six months ended June 30, 2001 and 2000 does not include the effect of: Six Months Ended June 30, --------------------------- 2001 2000 ----------- ----------- Stock options outstanding for: 1993 and 1997 Stock Option Plans 860,280 873,940 Shares of Common Stock issuable upon the exercise of warrants 3,997,382 4,018,238 Shares of Common Stock issuable upon the exercise of an option to purchase Unit Purchase Options granted to underwriter 190,400 190,400 Common Stock issuable upon the conversion of Series A Preferred Stock 5,373,134 5,373,134 ----------- ----------- Total 10,421,196 10,455,712 =========== =========== Note 7 - Recent Accounting Pronouncements In June 2001, the FASB issued SFAS No. 141, "Business Combinations." SFAS No. 141 requires that the purchase method of accounting be used for all business combinations initiated after June 30, 2001. Use of the pooling-of-interest method will be prohibited. The Company has evaluated this standard and believes that adoption will not have an impact on its condensed consolidated financial statements. In July 2001, the FASB issued SFAS No. 142, "Goodwill and Other Intangible Assets." SFAS No 142, which changes the accounting for goodwill from an amortization method to an impairment-only approach, will be effective for fiscal years beginning after December 15, 2001. The Company has evaluated this standard and believes that adoption will not have an impact on its condensed consolidated financial statements. (8)

Note 8 - Manufacturing and Supply Agreement, and Subscription Agreement On March 28, 2001 the Company entered into a Manufacturing and Supply Agreement (the "Agreement") with Ferrotec Corporation, a Tokyo based manufacturer. The Agreement grants to Ferrotec the exclusive right to manufacture CCS units in certain countries (the "Territory"), for ultimate distribution by Amerigon to its customers within the Territory, with the understanding that the parties will enter into good faith negotiations to establish a joint venture for the purpose of purchasing, marketing, selling and distributing the CCS units in the Territory. The Territory includes China, Japan, Taiwan, Korea, India, Thailand, Vietnam, Malaysia, Indonesia and the Philippines. The initial term of the Agreement begins April 1, 2001 and expires on April 1, 2011. The $2,000,000 fee is being amortized on a straight-line basis over the term of the Agreement. Ferrotec also entered into a Subscription Agreement with the Company, whereby Ferrotec purchased 200,000 shares of unregistered Common Stock at $5 per share. The Subscription Agreement grants Ferrotec demand registration rights beginning one year from the closing of the Subscription Agreement and piggy-back registration rights if the Company proposes to register any securities before then. The Company received the $2,000,000 and $1,000,000 payments under the two agreements in April 2001. Note 9 - Private Placement On June 14, 2000, the Company completed the sale of 2,200,000 restricted shares of its Common Stock in the private placement to selected institutional and accredited investors (the "Private Placement"), resulting in total proceeds of $11,000,000, less issuance costs of $1,300,000. The $11,000,000 excludes a $1,500,000 advance on the Bridge Loan (see Note 10) that was exchanged for 300,000 shares of Common Stock and issued to Westar Capital II LLC ("Westar") and Big Beaver Investments LLC ("Big Beaver"), the owners of Big Star, the lender on the Bridge Loan. As partial compensation for services rendered in the private placement, Roth Capital Partners, Inc., was granted a warrant to purchase up to 188,000 shares of the Company's Common Stock at $5 per share. The value of such warrant of $1,400,000 was determined using the Black-Scholes model and was reflected as non-cash offering expense. Note 10 - Bridge Loan On March 16, 2000, the Company obtained a Bridge Loan from Big Star Investments LLC (a limited liability company owned by Westar and Big Beaver, the Company's two principal shareholders) for an initial advance of $1,500,000. The Company took a second advance of $1,000,000 on May 10, 2000. The loan accrued interest at 10% per annum. The terms of the Bridge Loan specified that the principal and accrued interest were convertible at any time into Common Stock at a conversion price (the "Conversion Price") equal to the average daily closing bid price of the Common Stock during the ten-day period preceding the date of each Bridge Loan advance. This Conversion Price was $18.84 and $9.86 per share for the $1,500,000 and $1,000,000 advances, respectively. The Conversion Price was contingently adjustable in the event the Company issued in excess of $5,000,000 of equity securities in an offering at an issuance price less than the initial Conversion Price with respect to the Bridge Loan. Due to the Company's Private Placement of equity securities in June 2000 (Note 9) at an issuance price of $5 per share, the Conversion Price of the Bridge Loan was adjusted to $5 per share. This adjustment of the Conversion Price resulted in a non-cash charge to interest expense and a credit to additional paid-in capital of $2,500,000, because it met the definition of a "beneficial conversion feature" in accordance with Emerging Issues Task Force Consensus 98-5. (9)

Note 10 - Bridge Loan (cont.) In connection with entering into the Bridge Loan, the Company issued warrants for the right to purchase 7,963 and 10,146 shares of the Company's Common Stock relating to the $1,500,000 and $1,000,000 Bridge Loan advances, respectively (an amount equal to 10% of the principal amount of the advance divided by the original Conversion Price of $18.84 and $9.86, respectively.) The Conversion Price of the warrants was adjustable in the same manner as the Bridge Loan. The proceeds of the Bridge Loan were allocated between the Bridge Loan and the warrants based upon their estimated relative fair values. The allocated value of the warrants resulted in a discount of $173,000 to the Bridge Loan, of which $57,000 was amortized to interest expense, $68,000 was offset against extraordinary gain and $48,000 was offset against paid-in capital during the quarter ended June 30, 2000. The Company repaid $1,000,000 of Bridge Loan principal and accrued interest of $49,000 on June 16, 2000 with proceeds from the Private Placement (Note 9). The Company's $1,000,000 payment was allocated for accounting purposes between reacquiring the beneficial conversion feature and the debt. Due to this allocation, the debt was extinguished for less than its net book value, resulting in a $775,000 extraordinary gain on extinguishment of debt. The remaining $1,500,000 of Bridge Loan principal was exchanged for 300,000 shares of Common Stock, which was issued equally to Westar and Big Beaver. Note 11 - Ford Agreement On March 27, 2000, the Company entered into a Value Participation Agreement ("VPA") with Ford Motor Company ("Ford"). Pursuant to the VPA, Ford agreed that, through December 31, 2004, the Company has the exclusive right to manufacture and supply CCS units to Ford's Tier 1 suppliers for installation in Ford, Lincoln and Mercury branded vehicles produced and sold in North America (other than Ford badged vehicles produced by AutoAlliance International, Inc.). Ford is not obligated to purchase any CCS units under the VPA. As part of the VPA, the Company will grant to Ford warrants exercisable for Common Stock. A warrant for the right to purchase 82,197 shares of Common Stock at an exercise price of $2.75 per share was issued and fully vested on March 27, 2000. The fair value of the warrant of $1,148,000 was determined using the Black-Scholes valuation model and was recorded as a deferred exclusivity fee on the consolidated balance sheet. This fee is being amortized on a straight-line basis from April 2000 to December 2004, the initial term of the Agreement. In addition, Ford received an additional warrant for 26,148 shares of Common Stock due to certain anti-dilution provisions of the VPA that were triggered by the Company's Private Placement in June 2000. The fair value of the additional warrant of $220,000 was determined using the Black-Scholes model and has been accounted for in the same manner as the deferred exclusivity fee. Additional warrants will be granted and vested based upon purchases by Ford's Tier 1 suppliers of a specified number of CCS units throughout the length of the VPA. The exercise price of these additional warrants depends 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 Common Stock. (10)

Note 12 - Segment Reporting The Company operated primarily one business segment during the three and six months ended June 30, 2001 and 2000. The Company's Radar segment, which was discontinued in December 2000, was not significant to the Company's financial results in 2000.

For the three months ended June 30, 2000, one domestic customer represented 98% of the Company's sales. For the six months ended June 30, 2001, one domestic customer and one foreign customer represented 33% and 64% of the Company's sales, respectively. For the six months ended June 30, 2000, one domestic customer represented 97% of the Company's sales.

Due to this reduction, only one Class A Warrant is required to purchase one share of Common Stock; previously, five Class A Warrants were required to purchase one share of Common Stock. The total number of publicly traded Class A Warrants outstanding was adjusted to approximately 1,468,778, down from approximately 7,343,890, prior to the reduction. The Company's Class A Warrants trade under the symbol ARGNW. The issuance of 2,500,000 shares of Common Stock in June 2000 triggered certain anti-dilution provisions in the Class A Warrants which required the Company to issue additional warrants to purchase 524,486 shares of Common Stock. As a result, the number of Class A Warrants outstanding increased to 1,993,264. As a result of the warrant issued to Ford in March 2000, and the issuance of the 2,500,000 shares of Common Stock in June 2000, the total exercise price for each publicly traded warrant has been lowered from $25.00 to $17.795. (11)

ITEM 2 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS General We design, market and manufacture proprietary high technology electronic components and systems for sale to car and truck original equipment manufacturers ("OEMs"). In 2000, we completed our first full year of producing and selling our Climate Control Seat(TM) ("CCS(TM)"), which provides year-round comfort by providing both heating and cooling to seat occupants. 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 are now focusing our efforts on the CCS system, our only commercial product. We are now operating as a supplier to the automotive industry. Inherent in this market are costs and expenses well in advance of the receipt of orders (and resulting revenues) from customers. This is due in part to OEMs requiring the coordination and testing of proposed new components and sub-systems. Revenues from these expenditures may not be realized for two to three years as the OEMs tend to group new components and enhancements into annual or every two to three year vehicle model introductions. In addition, we believe that in light of the current economic conditions, lower industry volumes and other factors, that new vehicle production volumes for OEMs in 2001 will be lower than levels in 2000. Reduced demand for new vehicles could have an impact on our financial results for fiscal year 2001. Results of Operations Second Quarter 2001 Compared with Second Quarter 2000 - ----------------------------------------------------- Revenues. Revenues for the three months ended June 30, 2001 (the "Second Quarter 2001") were $1,117,000 on approximately 16,900 units compared with revenues of $944,000 on approximately 13,400 units for the three months ended June 30, 2000 (the "Second Quarter 2000"). This increase of $173,000, or 18%, is due to higher sales to NHK for the Lexus LS 430, from $16,000 in the Second Quarter 2000 to $560,000 in Second Quarter 2001. Shipments to NHK began in late June 2000, therefore, there were very few units shipped in Second Quarter 2000 compared to a full three months of shipments in Second Quarter 2001. The higher NHK sales were partially offset by lower sales to JCI for the Lincoln Navigator, from $924,000 in Second Quarter 2000 to $456,000 in Second Quarter 2001. The lower sales to JCI are due to softening sales of the Lincoln Navigator, a slowdown in the economy in general, and in the automobile industry in particular. Cost of Sales. Cost of sales increased to $870,000 in the Second Quarter 2001 from $801,000 in the Second Quarter 2000. This increase of $69,000, or 9%, is due to the higher sales volume of CCS units in the Second Quarter 2001. The gross margin increased to 22.11% compared to 15.15% for 2000 due to higher tooling reimbursements and fixed costs being spread over the higher production volume in 2001. We anticipate cost of sales to increase in absolute dollars while decreasing as a percentage of revenue as sales volume increases. Cost of sales includes tooling costs and related reimbursements. Net reimbursements of $95,000 and $3,000 were recorded for the Second Quarter of 2001 and the Second Quarter of 2000, respectively. (12)

Results of Operations (cont.) Research and Development Expenses. Research and development expenses decreased to $924,000 in Second Quarter 2001 from $1,093,000 in Second Quarter 2000. This $169,000, or 15%, decrease was due primarily to the discontinued investment in our AmeriGuard product. We also experienced lower costs relating to our first generation CCS device due to the advanced stage of its development. The costs reductions were partially offset by development costs relating to the next generation CCS device and BSST's research and development costs. BSST research and development costs were $417,000 for the Second Quarter 2001. Selling, General and Administrative Expenses. Selling, general and administrative expenses decreased to $1,097,000 in Second Quarter 2001 compared to $1,150,000 in the Second Quarter 2000. This $53,000, or 5%, decrease was due to lower professional fees, partially offset by an increase in costs for our office in Europe. We group development and prototype costs and related reimbursements in research and development. This is consistent with accounting standards applied in the automotive industry. Costs for tooling, net of related reimbursements, are included in cost of sales. Six Months Ended June 30, 2001 Compared with the Six Months Ended June 30, 2000 - -------------------------------------------------------------------------------- Revenues. Revenues for the six months ended June 30, 2001 were $3,452,000 as compared with revenues of $1,898,000 for the six months ended June 30, 2000. This increase of $1,554,000, or 82%, is due to the increase in customer platforms in 2001. We had two primary customers during 2001, Johnson Controls Incorporated and NHK Spring Company, LTD, and provided CCS for three platforms, the Lincoln Navigator, Lexus LS 430 and Toyota Celsior as compared to one customer, Johnson Controls, and one platform, the Lincoln Navigator, in 2000. The additional customer and platforms resulted in higher sales volume in 2001 as the number of CCS units shipped increased to 53,000, or 97%, from 27,000 in 2000. Cost of Sales. Cost of sales increased to $2,905,000 in 2001 from $1,646,000 in 2000. This increase of $1,259,000, or 77%, is due to the higher sales volume of CCS units in 2001. The gross margin increased to 15.85% compared to 13.28% for 2000 due to higher tooling reimbursements and fixed costs being spread over the higher production volume in 2001. We anticipate cost of sales to increase in absolute dollars while decreasing as a percentage of revenue as sales volume increases. Cost of sales includes tooling costs and related reimbursements. Net reimbursements of $150,000 and $10,000 were recorded for 2001 and 2000, respectively. Research and Development Expenses. Research and development expenses decreased to $1,804,000 in 2001 from $1,941,000 in 2000. This $137,000, or 7%, decrease was due primarily to the discontinued investment in our AmeriGuard product. We also experienced lower costs relating to our first generation CCS device due to the advanced stage of its development. The costs reductions were partially offset by development costs relating to the next generation CCS device and BSST's research and development costs. BSST research and development costs were $417,000 for 2001. Selling, General and Administrative Expenses. Selling, general and administrative expenses decreased to $2,356,000 in 2001 compared to $2,470,000 in the 2000. This $114,000, or 5%, decrease was due primarily to lower professional fees in 2001, partially offset by costs associated with the opening of our European office. We also recorded $146,000 in amortization for the warrants granted to Ford Motor Company relating to the Value Participation Agreement in 2001, compared to $62,000 in 2000. These higher costs were offset by a decrease in compensation related expense due to a $415,000 bonus accrued in 2000, compared to no accrual in 2001. (13)

Liquidity and Capital Resources As of June 30, 2001, we had net working capital of $2,832,000. We also had cash and cash equivalents of $749,000 at June 30, 2001. Our principal sources of operating capital have been the proceeds of our various financing transactions and, to a lesser extent, CCS product revenues and sale of prototypes to customers. As of June 30, 2001, our cash and cash equivalents decreased by $2,103,000 in 2001 from $2,852,000 at December 31, 2000. Cash used in operating activities amounted to $4,023,000, which was mainly attributable to the net loss of $3,565,000. Cash used in investing activities amounted to $1,078,000, which is mainly attributable to the purchase of equipment of $205,000 and the increase in restricted cash of $873,000 (see Note 4). Financing activities provided $2,998,000. This is due to Ferrotec payments of $3,000,000 slightly offset by $2,000 in capital lease payments. In April 2001, Ferrotec Corporation, a Tokyo-based manufacturer, paid us $2,000,000 in connection with a 10-year manufacturing and supply agreement for the exclusive right to manufacture CCS units in China, Japan, Taiwan, Korea, India, Thailand, Vietnam, Malaysia, Indonesia and the Philippines, for ultimate distribution by us to our customers within those countries. Concurrently, paid an additional $1,000,000 for the purchase 200,000 unregistered shares of our common stock. In May 2001, we announced that the CCS system has been selected to be included in four additional automotive platforms, which are expected to be introduced over the next 18 months and bringing to eight the total number of automotive platforms where the CCS system has been selected to be included as either an optional or standard feature. For confidentiality reasons, however, we are not permitted to identify the four additional automotive platforms and the automotive and seat manufacturers at this time. BSST LLC was established in August 2000 by Dr. Lon E. Bell, the founder of Amerigon. BSST is engaged in a research and development effort to improve the efficiency of thermoelectric devices. In September 2000, we entered into an option agreement with BSST to purchase a 90% interest in BSST for an aggregate of $2,000,000. We paid to BSST $150,000 for the option rights at that time. The original option agreement was amended to extend the termination date from January 31, 2001 to May 31, 2001, in exchange for additional option payments totaling $360,000. On May 31, 2001, we exercised our option by paying $400,000 to BSST. After August 31, 2001, BSST can require us to contribute additional capital of up to $400,000 in any three month period, until the remaining $1,090,000 is paid under the Option Agreement. Should we miss any of these payments, our ownership in BSST would be reduced proportionately. In addition, we have, as the majority owner of BSST, certain funding obligations to BSST of up to $500,000 per year. Until we are selling units in the automotive market with an appropriate margin and volume, we expect to incur losses for the foreseeable future. There can be no assurance that profitability can be achieved in the future. The volume production we expect for the Lincoln Navigator SUV, Lincoln Blackwood, Lexus LS 430 and Toyota Celsior as well as the four new platforms will not generate sufficient revenue to meet our operating needs. Sufficient volume will not be reached in the near term, as automotive industry development timing tends to be relatively long. Although we are working with many automobile manufacturers for future introduction of our CCS technology, most of them will not introduce the product until the 2003 model year (2002 calendar year) and beyond, and there is no guarantee that any manufacturer will introduce the Company's products. Larger orders for the CCS products will require significant expenses for tooling and to set up manufacturing and/or assembly processes. We also expect to require significant capital to fund other near-term production engineering and manufacturing, as well as research and development and marketing of these products. We do not intend to pursue any more significant grants or development contracts to fund operations and therefore are highly dependent on current working capital sources. Based on our current operating plan, we believe existing cash and working capital are not sufficient to meet our anticipated financial requirements. We believe that current cash balances, together with the funds previously received from the Ferrotec Corporation, will be sufficient to meet our operating needs through the end of August 2001. (14)

Liquidity and Capital Resources (cont.) We will need to raise additional cash from financing sources before we can achieve profitability from our operations. We are currently negotiating a bridge financing while considering pursuit of additional funds through additional debt or equity financing or through strategic corporate partnerships. We also plan, in the next 12 months, to attempt to obtain a line of credit secured by the Company's receivables and to reduce discretionary spending to the extent feasible. There can be no assurance that any additional financing will be available on acceptable terms, if at all. Failure to raise additional capital would have a material adverse effect on our ability to continue as a going concern and to achieve our intended business objectives. Other Information Certain matters discussed or referenced in this report, including our intention to develop, manufacture and market the CCS product, our expectation of increased revenues and continuing losses, our financing requirements, our capital expenditures and our prospects for the development of platforms with major automotive manufacturers, are forward-looking statements. Other forward-looking statements may be identified by the use of forward-looking terminology such as "may", "will", "expect", "believe", "estimate", "anticipate", "continue", or similar terms, variations of such terms or the negative of such terms. Such statements are based upon our current expectations and are subject to a number of risks and uncertainties which could cause actual results to differ materially from those described in the forward looking statements. Such risks and uncertainties include the market demand for and performance of our products, our ability to develop, market and manufacture such products successfully, the viability and protection of our patents and other proprietary rights, and our ability to obtain new sources of financing. Additional risks associated with us and our business and prospects are described in our Annual Report on Form 10-K for the year ended December 31, 2000. (15)

ITEM 3 QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Our exposure to market risk for changes in interest rates relate primarily to our investment portfolio. We place our investments in debt instruments of the U.S. government and in high-quality corporate issuers. We seek to ensure the safety and preservation of its invested funds by limiting default risk and market risk. We have no investments or transactions denominated in foreign country currencies and therefore are not subject to foreign exchange risk. There have been no material changes with respect to market risk since the Form 10-K was filed for our year ended December 31, 2000. (16)

ITEM 5. Other Information ----------------- On May 23, 2001, the Board of Directors appointed Francois J. Castaing to fill a vacancy on the Board. Mr. Castaing was most recently technical advisor to the Chairman of Chrysler Corporation, now DaimlerChrysler. Prior to that, he was Executive Vice President and ran Chrysler International Operations outside of North America. After spending thirteen years with Chrysler, Mr. Castaing retired in 2000. From 1980 to 1987, he was with American Motors where he was Vice President of Engineering and later Group Vice President Product and Quality until Chrysler acquired that company. Mr. Castaing began his career with Renault in France as Technical Director for Renault Motorsport Programs. On May 31, 2001, we exercised our option pursuant to an Option Agreement dated September 4, 2000 to acquire a controlling interest in BSST LLC, a Delaware limited liability company. BSST was founded by Dr. Lon E. Bell, the founder and a director of Amerigon, and is engaged in a research and development effort to improve the efficiency of thermoelectric devices. The objective of these efforts is to expand the applications of thermoelectric devices to new applications. Dr. Lon Bell has resigned his position as Chief Technology Officer of Amerigon in order to devote his attention full-time to BSST. The Option Agreement gave us the option to purchase 2,000 Series A preferred units of BSST for $2,000,000, which represented 90 percent ownership in BSST as of May 31, 2001. We paid BSST a non-refundable option payment of $150,000 for the option on September 6, 2000. In January 2001, we amended the Option Agreement to extend the termination date of the option from the initial expiration date of January 31, 2001. In exchange for non-refundable option extension payments of $60,000, $80,000, $100,000 and $120,000, made at end of January, February, March and April, respectively, the expiration date was extended to May 31, 2001. The option extension payments were also applied against the $2,000,000. After August 31, 2001, BSST can require us to contribute additional capital of up to $400,000 in any three month period, until the remaining $1,090,000 is paid under the Option Agreement. Should we miss any of these payments, our ownership in BSST would be reduced proportionately. In addition, we have, as the majority owner of BSST, certain funding obligations to BSST of up to $500,000 per year. Dr. Bell had previously assigned his intellectual rights to BSST with respect to thermoelectric devices and an unspecified amount of cash, not to exceed $50,000, in return for 100,000 common units, which represented 10 percent ownership of BSST as of May 31, 2001. Dr. Bell serves as the president and chief executive officer of BSST and has entered into a one-year employment contract with BSST effective as of June 1, 2001 with a base rate of $180,000 per year and received an option for 58,824 common units, which vest upon the achievement of certain milestones. Dr. Bell also received certain anti-dilution rights, preemptive rights, and equity step-up rights. ITEM 6.

ARTICLE III PAYMENT DISCLAIMER AND REALLOCATION; PERMITTED ASSIGNMENTS 3.1 Payment Disclaimer and Reallocation.

Upon approval of the Board of Directors of the Company of such a disclaimer, which approval shall not be unreasonably withheld, the Inventor shall have the right to reallocate the amount of Contract Payment disclaimed by the Inventor to current or former officers, employees, consultants and contractors of the Company.

Payment that should be paid to the assignee. Following any such assignment, the Inventor shall have no further right or interest in the assigned portion of the Contract Payment and the assignee shall become a Holder of a Contract Payment Interest and treated as "Inventor" for all purposes hereunder with respect to his or her applicable percentage of the Contract Payment (other than with respect to Section 2.6).

The Company need not investigate any fact or matter stated in the written notice. ARTICLE IV AUDIT RIGHTS; OWNERSHIP; SALE OF TECHNOLOGY 4.1 Accounting Records re Exploitation; Audit Rights. ------------------------------------------------ (a) The Company shall keep books of account relating to its operations, together with records supporting the same (all of which are hereinafter referred to as "records"). The Inventor may audit the applicable records at the place where the Company maintains the same in order to verify Statements rendered hereunder. Any such audit shall be conducted by a reputable public accountant during reasonable business hours in such manner as not to interfere with the Company's normal business activities. In no event shall an audit with respect to any Statement commence later than 24 months from end of the Fiscal Quarter to which such Statement relates; nor shall audits be made hereunder more frequently than once annually; nor shall the records supporting any Statement be audited more than once. All Statements rendered hereunder shall be binding upon the Inventor and not subject to objection for any reason if the Inventor has not commenced an audit thereof within 24 months from the end of the Fiscal Quarter to which a Statement relates. If the Company, as a courtesy to the Inventor, shall include cumulative figures in any Statement, the time within which the Inventor may commence any audit or make any objection in respect of any statement shall not be enlarged or extended thereby. Subject to Section 4.1(c), the fees and expenses incurred by the public accountant retained by the Inventor in connection with any audit under this Section 4.1(a) shall be divided evenly between the Company and the Inventor, provided that the Company shall not be obligated to pay more than $25,000 of such fees and expenses per audit. (b) If the Inventor contests any computations made in connection with a Statement, the Inventor shall provide written notice to the Company stating each item as to which the Investor takes exception, specifying reasonable detail the nature and extent of any such exception. If a proposed change is disputed by the Company, then the Company and the Inventor shall negotiate in good faith to resolve such dispute. If, after a period of 20 days following the date on which the Inventor gives the Company notice of any proposed change which remains disputed, then the Company and the Inventor shall choose any independent firm of public accountants of nationally recognized standing other than the auditor of Amerigon Incorporated or the Company at such time to resolve any remaining dispute. The accounting firm shall act as an arbitrator to determine, based solely on presentations by the parties and not by independent review, only those issues still in dispute. The decision of the accounting firm shall be final and binding. All of the fees and expenses of the accounting firm shall be paid 5

equally by the Company and the Investor; provided, however, that if the -------- ------- accounting firm determines that either party's position is totally correct, then the other party shall pay 100% of the costs and expenses incurred by the accounting firm in connection with any such determination. Any disputes other than computational errors shall be settled in accordance with Sections 5.6 and 5.7. (c) If any audit of the Company's records by the Inventor reveals that the Company has failed to properly account for and pay the Inventor the Contract Payment that should have been paid for any Fiscal Quarter, and the amount of any Contract Payment which the Company has failed to properly account and pay for in aggregate in any Fiscal Year exceeds by 5% or more, the amount of Contract Payment actually accounted for and paid to the Inventor for such Fiscal Year, the Company shall, in addition to paying the Inventor such overdue percentage of Contract Payment, pay the Inventor an additional 10% of the Contract Payment that should have been paid for that Fiscal Year and reimburse the Inventor for his direct, reasonable out-of-pocket expenses incurred in conducting such audit. (d) Any license, agreement, contract or similar arrangement entered into Company with a third party in which Royalty Receivables are receivable by the Company shall contain usual and customary rights to audit such third party. The Inventor shall have access to all records received by the Company from such third parties supporting Royalties Receivable and Covered Revenues received from such third party for which a Contract Payment is payable to the Inventor. The Inventor shall further have the right to request the Company to exercise the Company's audit rights with respect to third parties under any license, agreement, contract or similar arrangement entered for which Royalty Receivables are receivable and the Company shall reasonably comply with such request. 4.2 Ownership. The Inventor expressly acknowledges that the Inventor has --------- and will have no right, title or ownership interest of any kind or character whatsoever in or to the Basic Technology, or to the literary, scientific or engineering material upon which the Basic Technology is based, or from which it may be adapted, and no lien thereon or other rights thereto, except as expressly provided herein and any reversionary rights upon a liquidation or winding up of the Company; and that the same shall be and remain the Company's sole and exclusive property. Subject to the Inventor's rights hereunder, including, without limitation, the Inventor's rights under Section 2.6, the Company shall have the sole and exclusive right to utilize, sell, license or otherwise dispose of all or any part of its rights in the Basic Technology or such literary, scientific or engineering material. The Company shall not be obligated to segregate Contract Payment from its other funds, it being the intent and purpose hereof that Contract Payment is referred to herein merely as a measure in determining the time and manner of payment to Inventor. The Contract Payment is unfunded by the Company and subject to the claims of the Company's creditors. 4.3 Exploitation. As between the Inventor and the Company, subject to ------------ Section 2.6, the Company shall have complete authority to exploit the Basic Technology and license the incorporation and use thereof throughout the world. The Company shall have the broadest possible latitude in the exploitation of the Basic Technology, and the exercise of its judgment in good faith in all matters pertaining thereto shall be final. The Company has not made any express or implied representation, warranty, guarantee or agreement as to the amount of proceeds 6

which will be derived from the exploitation of the Basic Technology, nor has the Company made any express or implied representation, warranty, guarantee or agreement that there will be any sums payable to Inventor hereunder, or that the Basic Technology will be favorably received by manufacturers or consumers, or will be exploited continuously. In no event shall the Company incur any liability based upon any claim that the Company has failed to realize receipts or revenue which should or could have been realized. Subject to Section 2.6, the Company may exploit the Basic Technology itself or through such licensees, sublicensees and other parties as the Company may, in its uncontrolled discretion, determine, upon such terms and conditions as the Company may deem advisable, and the Company may refrain from exploiting the Basic Technology in any territory for any reason whatsoever. 4.4 Sale of Technology. The Company shall have the right at any time to ------------------ sell, transfer or assign all or any of its rights in and to the Basic Technology. Any such sale, transfer or assignment shall be subject to the Inventor's rights hereunder, and upon the purchaser, transferee or assignee assuming performance of this Agreement in place and stead of the Company, the Company shall be released and discharged of and from any further liability or obligation hereunder. No part of any sales price or other consideration received by, or payable to, the Company shall be included in the Company's Covered Revenues and the Inventor shall have no rights under this Agreement in respect of any thereof.

No amendment, modification, termination or waiver of any ---------- provision of this Agreement, shall be effective unless the same shall be in writing and signed by Inventor and, on behalf of the Company, by a senior executive officer after approval thereof by the Board of Directors. Any such waiver or consent shall be effective only in the specific instance and for the specific purpose for which it was given. 5.4 Severability. If any provision of this Agreement is held invalid or ------------ unenforceable, the remainder of this Agreement shall nevertheless remain in full force and effect, and if any provision is held invalid or unenforceable with respect to particular circumstances, it shall 7

nevertheless remain in full force and effect in all other circumstances, to the fullest extent permitted by law. 5.5 Integration.

The Series A Member may be ----------------------------- requested to provide to the Company on an annual basis the difference between $500,000 and the amount of the Company's free cashflow as certified in the Certificate, to the extent such free cashflow is less than $500,000; provided, however, that the obligation of the Series A Member shall in no circumstance be greater than $500,000 per year. Such additional funding from the Series A Member may be in the form of additional Capital Contributions contributed to the Company in exchange for additional Series A Preferred Units. Within sixty (60) days after receipt of the Certificate and audited financial statements from the Company, the Series A Member shall either approve or reject such request by Company in its sole discretion. (iii) Effect of Disapproval. In the event the Series A Member --------------------- decides to reject the Company's request for additional financing, the Company may obtain alternative financing from another person on terms and conditions satisfactory to the Board. If the Company does not obtain such alternative financing by June 30 of the year following the Fiscal Year for which financial statements were delivered pursuant to Section 3.5(a)(i), then the Company shall commence liquidation pursuant to Section 14.1 unless the Board unanimously votes against proceeding with liquidation. (iv) Obligations Continuing. Notwithstanding the conversion of ---------------------- all Series A Preferred Units to Class B Common Units, the obligations of the Series A Member under this Section 3.5(a) shall continue for so long as the Series A Member is a holder of any Units until the occurrence of a Special Event. (b) Other Additional Capital Contributions. No Person may voluntarily make -------------------------------------- any Capital Contribution without the approval of the Board. SECTION 3.6 Withdrawal of Capital. No Member shall be entitled to --------------------- withdraw all or any part of such Member's Capital Contribution or Capital Account from the Company prior to the Company's Dissolution or Liquidation. SECTION 3.7 No Interest on Capital. No Member shall be entitled to ---------------------- receive interest on such Member's Capital Account or any Capital Contribution except as provided herein. SECTION 3.8 Priority and Return of Capital. Except as specifically ------------------------------ provided in this Agreement with respect to the Series B Preferred Units, no Member shall have priority over any other Member, whether for the return of a Capital Contribution or any portion of a Capital Account or for a Distribution or an allocation of Net Profits or Net Losses; provided, however, that this Section 3.8 shall not apply to loans or other indebtedness (as distinguished from a Capital Contribution) made by a Member to the Company. 12

SECTION 3.9 Substituted Member. ------------------ (a) Admission of Substituted Member. A prospective transferee (other than ------------------------------- an existing Member) of a Membership Interest may be admitted as a Member with respect to such Membership Interest ("Substituted Member") only on such prospective transferee executing a counterpart of this Agreement as a party hereto. Any prospective transferee of a Membership Interest shall be deemed an Assignee and, therefore, the owner of only an Economic Interest until such prospective transferee has been admitted as a Substituted Member. Except as otherwise permitted in the DLLCA, any such Assignee shall be entitled only to receive allocations and distributions under this Agreement with respect to such Membership Interest and shall have no right to vote or exercise any rights of a Member until such Assignee has been admitted as a Substituted Member. Until the Assignee becomes a Substituted Member, the Assigning Member shall continue to be a Member and to have the power to exercise any rights and powers of a Member under this Agreement, including the right to vote in proportion to the Percentage Interest that the Assigning Member would have had in the event that the assignment had not been made. (b) Consequences of Substitution. Any Person admitted to the Company as a ---------------------------- Substituted Member shall be subject to all the provisions of this Agreement that apply to the Member from whom the Membership Interest was assigned; provided, however, that the Assigning Member shall not be released from liabilities as a Member solely as a result of the assignment, both with respect to obligations to the Company and to third parties, incurred prior to the assignment. SECTION 3.10 Representation and Warranties. Each Member hereby ----------------------------- represents and warrants to the Company and each other Member that: (a) if that Member is an organization, (i) that it is duly organized, validly existing, and in good standing under the law of its jurisdiction of organization, (ii) it has full organizational power to execute and agree to this Agreement and to perform its obligations hereunder, and (iii) this Agreement is a valid and binding obligation of such Member, enforceable against such Member in accordance with its terms, except as the enforceability thereof may be limited by bankruptcy, insolvency, fraudulent conveyance, fraudulent transfer, reorganization, moratorium or other similar laws relating to the enforcement of creditors' rights generally and by general principles of equity; (b) the Member is acquiring its Units in the Company for the Member's own account as an investment and without an intent to distribute the interest in violation of applicable securities laws; and (c) the Member acknowledges that the Units have not been registered under the Securities Act or any state securities laws, and may not be resold or transferred by the Member without appropriate registration or the availability of an exemption from such requirements, and in accordance with the terms of this Agreement. ARTICLE IV -- RIGHTS, PREFERENCES AND PRIVILEGES ----------------------------------- OF THE CLASS A COMMON UNITS --------------------------- SECTION 4.1 Anti-Dilution Protection. After a Majority in Interest ------------------------ of the Series A Preferred Units has reasonably determined that the Milestone has been achieved by the Company, the Class A Member shall be entitled to receive, upon the issuance and sale of New 13

Securities, additional Class A Common Units so that the Class A Member's Percentage Interest shall be the same Percentage Interest as held by the Class A Member immediately prior to the issuance of the New Securities; provided, that upon reaching such Milestone, the Class A Member shall receive additional Class A Common Units based on the issuance and sale of any New Securities issued and sold by the Company since the Effective Date, such that the Class A Member will have the number of Class A Common Units to which it otherwise would be entitled under the first proviso of this Section 4.1 but for the condition precedent of achieving the Milestone. (a) No Fractional Units. No fractional Class A Common Units shall be ------------------- issued upon the operation of this Section 4.1 and the number of units of Class A Common Units to be issued shall be rounded to the nearest whole unit. (b) Expiration. Notwithstanding any other provision of this Agreement, the ---------- anti-dilution rights of the Class A Member may not be assigned or transferred other than to a person in the Family Group of the initial Class A Member and shall expire upon the earlier of (i) the consummation of a Qualified IPO or (ii) the receipt by the Company of $10,000,000 in aggregate gross proceeds from the sale of New Securities after the Effective Date; provided, that if the Milestone is achieved subsequent to such event, the Class A Member shall receive additional Class A Common Units as contemplated by the proviso of the first paragraph of this Section 4.1. SECTION 4.2 Preemptive Rights. Upon expiration of the anti- ----------------- dilution rights accorded to the Class A Member under Section 4.1, the Class A Member shall have the right to purchase up to the Class A Member's pro rata share of New Securities which the Company may, from time to time, propose to sell and issue. The Class A Member's pro rata share shall be equal to a number such that the Percentage Interest owned by the Class A Member after the issuance of New Securities is the same Percentage Interest as prior to the issuance of New Securities. (a) In the event the Company proposes to undertake an issuance of New Securities subject to this Section 4.2, it shall promptly give the Class A Member written notice of its intention, describing the type of New Securities, their price and the general terms upon which the Company proposes to issue the same. The Class A Member shall have 20 days after any such notice is mailed or delivered to agree to purchase the Class A Member's pro rata share of such New Securities for the price and upon the terms specified in the notice by giving written notice to the Company and stating therein the quantity of New Securities to be purchased. (b) If the Class A Member fails to exercise its preemptive right within said 20-day period, the Company shall have 120 days thereafter to sell or enter into an agreement (pursuant to which the sale of New Securities covered thereby shall be closed, if at all, within 60 days from the date of said agreement) to sell the New Securities respecting which the Class A Member's preemptive right was not exercised, at a price and upon terms no more favorable to the purchasers thereof than specified in the Company's notice to the Class A Member pursuant to Section 4.2(a). In the event the Company has not sold the New Securities or entered into an agreement to sell the New Securities in accordance with the foregoing 120 day period (and closed the sale of such New Securities within 60 days from the date of said agreement), the 14

Company shall not after such date issue or sell any New Securities, without first offering such securities to the Class A Member in the manner provided in Section 4.2(a) above. SECTION 4.3 Equity "Step-Up" Rights. ----------------------- (a) If the Class A Member does not completely vest the Initial Class A Member Options before the closing date of a Special Event that results in the Class A Member's Equity Ownership having an aggregate fair market value as determined in good faith by the Board of Directors on the closing date of such Special Event of at least $25,000,000 and, immediately prior to such date, the Class A Member's Equity Ownership comprises a Fully-Diluted Percentage Interest of less than 10%, then the Class A Member shall receive additional equity or cash proceeds in connection with the consummation of such Special Event equal in value to one-half of the difference between (i) the value of a Fully-Diluted Percentage Interest of 10% (as valued in the Special Event) and (ii) the value of the Class A Member's Equity Ownership immediately prior to such date (as valued in the Special Event); provided, there shall be deducted from proviso (i) above a value equal to the value of any Class A Common Units previously transferred to any Person not part of the Family Group of the initial Class A Member. (b) If the Class A Member does completely vest the Initial Class A Member Options before the closing date of a Special Event that results in the Class A Member's Equity Ownership having an aggregate fair market value as determined in good faith by the Board of Directors on the closing date of such Special Event of at least $25,000,000 and, immediately prior to such date, the Class A Member's Equity Ownership comprises a Fully-Diluted Percentage Interest of less than 15%, then the Class A Member shall receive additional equity or cash proceeds in connection with the consummation of such Special Event equal in value to one-half of the difference between (i) the value of a Fully-Diluted Percentage Interest of 15% (as valued in the Special Event) and (ii) the value of the Class A Member's Equity Ownership immediately prior to such date (as valued in the Special Event); provided, there shall be deducted from proviso (i) above a value equal to the value of any Class A Common Units previously transferred to any Person not part of the Family Group of the initial Class A Member. ARTICLE V -- RIGHTS, PREFERENCES AND PRIVILEGES OF ------------------------------------- THE SERIES A PREFERRED UNITS ---------------------------- SECTION 5.1 Distribution Provisions. In the event the Company ----------------------- shall declare a Distribution payable in cash, securities of other persons, evidences of indebtedness issued by the Company or other persons, assets (excluding cash dividends) or options or rights not referred to in subsection 5.3(d), then, in each such case for the purpose of this subsection 5.3(e), the Series A Members shall be entitled to a proportionate share of any such Distribution as though they were the holders of the number of Common Units into which their Series A Preferred Units are convertible as of the record date fixed for the determination of the holders of Common Units entitled to receive such Distribution. 15

SECTION 5.2 Liquidation Preference. ---------------------- (a) In the event of any Liquidation or Dissolution of the Company, either voluntary or involuntary, the Series A Members shall be entitled to receive, prior and in preference to any distribution of any of the assets of the Company to the Class A Members and the Class B Members, but subject to the prior rights of the initial Class A Member pursuant to Section 14.2(e), an amount per Series A Preferred Unit equal to the sum of (i) $1,000 for each Series A Preferred Unit (the "Original Issue Price"), (ii) an amount equal to 7% of the Original Issue Price annually, and (iii) an amount equal to any declared but unpaid distributions on such Series A Preferred Unit (the amounts in (ii) and (iii) being referred to herein as the "Premium"). If upon the occurrence of such event, the assets and funds thus distributed among the Series A Members shall be insufficient to permit the payment to such Members of the full aforesaid preferential amounts, then the entire assets and funds of the Company legally available for distribution shall be distributed ratably among the Series A Members in proportion to the amount of such Series A Preferred Units owned by each such Member. (b) Upon the completion of the distribution required by Section 5.2(a), if assets remain in the Company, the Class A Members and Class B Members shall receive all of the remaining assets. SECTION 5.3 Conversion. The Series A Member shall have conversion ---------- rights as follows (the "Conversion Rights"): (a) Right to Convert. Each Series A Preferred Unit shall be convertible, ---------------- at the option of the holder thereof, at any time after the date of issuance of such Unit, at the office of the Company or any transfer agent for such Units, into such number of fully paid and nonassessable Class B Common Units as is determined by dividing the Original Issue Price by the conversion price ("Conversion Price") applicable to such Unit, determined as hereafter provided, in effect on the date the certificate is surrendered for conversion. The initial Conversion Price per Series A Preferred Unit shall be $2.2222; provided, however, that the Conversion Price for the Series A Preferred Units shall be subject to adjustment as set forth in subsection 5.3(d). (b) Automatic Conversion. Each Series A Preferred Unit shall automatically -------------------- be converted into Class B Common Units at the Conversion Price at the time in effect for such Series A Preferred Unit immediately upon the date specified by written consent or agreement of the holders of a Majority in Interest of the Series A Preferred Units. (c) Mechanics of Conversion. Before any Series A Member shall be entitled ----------------------- to convert the same into Class B Common Units, it shall surrender the certificate or certificates therefor, duly endorsed, at the office of the Company or of any transfer agent for the Series A Preferred Units, and shall give written notice to the Company at its principal office, of the election to convert the same and shall state therein the name or names in which the certificate or certificates for Class B Common Units are to be issued. The Company shall, as soon as practicable thereafter, issue and deliver at such office to such Series A Member, or to the nominee or nominees of such holder, a certificate or certificates for the number of Class B Common Units to which such holder shall be entitled as aforesaid. Such conversion shall be 16

deemed to have been made immediately prior to the close of business on the date of such surrender of the Series A Preferred Units to be converted, and the person or persons entitled to receive the Class B Common Units issuable upon such conversion shall be treated for all purposes as the record holder or holders of such Class B Common Units as of such date. If the conversion is in connection with an underwritten offering of securities registered pursuant to the Securities Act of 1933, the conversion may, at the option of any holder tendering Series A Preferred Units for conversion, be conditioned upon the closing with the underwriters of the sale of securities pursuant to such offering, in which event the person(s) entitled to receive the Class B Common Units upon conversion of the Series A Preferred Units shall not be deemed to have converted such Series A Preferred Units until immediately prior to the closing of such sale of securities. (d) Conversion Price Adjustments of Series A Preferred Units for Certain -------------------------------------------------------------------- Dilutive Issuances, Splits and Combinations. The Conversion Price of the Series - ------------------------------------------- A Preferred Units shall be subject to adjustment from time to time as follows: (i) In the event the Company should at any time or from time to time after the date upon which any Series A Preferred Units were first issued (the "Purchase Date" with respect to such series) fix a record date for the effectuation of a split or subdivision of the outstanding Common Units or the determination of holders of Common Units entitled to receive a Distribution payable in additional Common Units without payment of any consideration by such holder for the additional Common Units (other than pursuant to Section 4.1), then, as of such record date (or the date of such Distribution, split or subdivision if no record date is fixed), the Conversion Price of the Series A Preferred Units shall be appropriately decreased so that the number of Class B Common Units issuable on conversion of each Series A Preferred Unit shall be increased in proportion to such increase of the aggregate of Common Units. In the event the Company shall declare or pay, without consideration, any Distribution on the Common Units payable in any right to acquire Common Units for no consideration, then the Company shall be deemed to have made a Distribution payable in Common Units in an amount of Units equal to the maximum number of Units issuable upon exercise of such rights to acquire Common Units. (ii) If the number of Common Units at any time after the Purchase Date is decreased by a combination of the outstanding Common Units, then, following the record date of such combination, the Conversion Price for the Series A Preferred Units shall be appropriately increased so that the number of Common Units issuable on conversion of each unit of such series shall be decreased in proportion to such decrease in Common Units. (iii) All adjustments to the Conversion Price will be calculated to the nearest cent of a dollar. No adjustment in the Conversion Price will be required unless such adjustment would require an increase or decrease of at least one cent per dollar; provided, however, that any adjustments which by reason of this Section 5.3(d)(iii) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All adjustments to the Conversion Price shall be made successively. (e) Recapitalizations and Reorganizations. If the Class B Common Units ------------------------------------- issuable upon conversion of the Series A Preferred Units shall be changed into or exchanged for a 17

different class or classes of units, or other securities or property whether by reorganization, recapitalization or otherwise (other than a subdivision, combination or merger or sale of assets transaction provided for elsewhere in this Section 5.3 or Section 5.2) provision shall be made so that the Series A Member shall thereafter be entitled to receive upon conversion of the Series A Preferred Units the number of units or other securities or property, to which a holder of Class B Common Units deliverable upon conversion would have been entitled on such recapitalization or reorganization. In any such case, appropriate adjustment shall be made in the application of the provisions of this Section 5.3 with respect to the rights of the Series A Member after the recapitalization or reorganization to the end that the provisions of this Section 5.3 (including adjustment of the Conversion Price then in effect and the number of shares purchasable upon conversion of the Series A Preferred Units) shall be applicable after that event as nearly equivalent as may be practicable. (f) No Impairment. This Company will not, by amendment of this Agreement ------------- or through any reorganization, recapitalization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith assist in the carrying out of all the provisions of this Section 5.3 and in the taking of all such action as may be necessary or appropriate in order to protect the Conversion Rights of the Series A Member against impairment. (g) No Fractional Units and Certificate as to Adjustments. ----------------------------------------------------- (i) No fractional units shall be issued upon the conversion of any Series A Preferred Units, and the number of Class B Common Units to be issued shall be rounded to the nearest whole unit. Such conversion shall be determined on the basis of the total number of Series A Preferred Units the holder is at the time converting into Class B Common Units and the number of Class B Common Units issuable upon such aggregate conversion. (ii) Upon the occurrence of each adjustment or readjustment of the Conversion Price of the Series A Preferred Units pursuant to this Section 5.3, the Company, at its expense, shall promptly compute such adjustment or readjustment in accordance with the terms hereof and prepare and furnish to each Series A Member a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Company shall, upon the written request at any time of any Series A Member, furnish or cause to be furnished to such holder a like certificate setting forth (A) any such adjustment and readjustment, (B) the Conversion Price for such series of Preferred Units at the time in effect, and (C) the number of Class B Common Units and the amount, if any, of other property which at the time would be received upon the conversion of a Series A Preferred Unit. (h) Reservation of Units Issuable Upon Conversion. The Company shall at --------------------------------------------- all times reserve and keep available out of its authorized but unissued Class B Common Units, solely for the purpose of effecting the conversion of the Series A Preferred Units, such number of its Class B Common Units as shall from time to time be sufficient to effect the conversion of all Series A Preferred Units; and if at any time the number of authorized but unissued Class B Common Units shall not be sufficient to effect the conversion of all then outstanding Series A Preferred Units, in 18

addition to such other remedies as shall be available to the holder of such Series A Preferred Units, the Company will take such action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued Class B Common Units to such number of Units as shall be sufficient for such purposes. SECTION 5.4 Voting Rights. The Series A Member shall have the ------------- right to one vote for each Class B Common Unit into which such Series A Preferred Unit could then be converted, and with respect to such vote, such holder shall have full voting rights and powers equal to the voting rights and powers of the holders of Class B Common Units, and shall be entitled, notwithstanding any provision hereof, to notice of any meeting of the Members in accordance with this Agreement and shall be entitled to vote, together with holders of the Common Units as a single class, with respect to any question upon which holders of the Common Units have the right to vote. ARTICLE VI -- MANAGEMENT ---------- SECTION 6.1 Manager; Management and Control; Day to Day Affairs of ------------------------------------------------------ the Company. The day-to-day business and affairs of the Company shall be - ----------- operated and managed by the Officers, provided that the affairs of the Company shall be overseen by the Board of Directors. Any Officer acting pursuant to authority granted by the Board or the provisions of this Agreement is authorized to take any actions, to make any determinations and to provide any consents permitted to be taken, made or provided by the Company under this Agreement; provided, however, that no Officer shall take any action, make any determination or provide any consent expressly reserved by this Agreement to the Members or to the Board of Directors or reserved to the Board of Directors pursuant to an action duly and validly taken by the Board of Directors. No Member or Director or Officer shall, acting individually, have the power to sign or bind the Company unless duly authorized to do so by the Board of Directors or this Agreement. Notwithstanding the foregoing, no Officer shall have liability to the Members or the Company for exceeding the authority granted to such Officer in the event a decision made or an action taken by such Officer was made or taken with a reasonable good faith belief that such decision or action was within the scope of the day-to-day business and affairs of the Company. The Board shall from time to time set the compensation for each of the Officers of the Company, and shall not be permitted to delegate such authority to any Officer or Officers (in their capacity as such). SECTION 6.2 Board of Directors. ------------------ (a) Designated Board. As of the date hereof, the members of the Board ---------------- shall be John W. Clark, Oscar B. Marx III, Richard A. Weisbart, and Dr. Lon E. Bell, and the Members desire to appoint a prominent figure in thermoelectrics recommended by the Class A Member to the Board. The Members shall promptly cause such a figure to be appointed to the Board. Following this initial Board composition, at each meeting of the Members for the election of directors or any solicitation of written consents for such purpose, the Class A Member and the Series A Member hereby agree to vote all Voting Interests entitled to vote in the election of directors now owned or hereafter acquired or controlled by them (collectively, the "Members' Voting Interests"), and otherwise use their best efforts as Members to elect the Designated 19

Board (as defined below), which shall constitute the entire Board. The "Designated Board" shall consist of (i) one member designated by the Class A Member, (ii) three members designated by the Series A Member, and (iii) one prominent figure in thermoelectrics recommended by the Class A Member and approved by a majority of the Directors not designated by the Class A Member. The Members hereby agree that, if the size of the Board of Directors is increased or decreased, the "Designated Board" shall consist of (i) one member designated by the Class A Member, (ii) one prominent figure in thermoelectrics, and (iii) all remaining members designated by the Series A Member; provided, however, that if the Class A Member's Percentage Interest is ever less than 5%, the Designated Board shall consist of members designated entirely by the Series A Member. (b) Failure to Vote per Agreement. In the event that any Series A Member ----------------------------- or Class A Member shall fail to vote its Voting Interests so as to achieve the structure of the Board and/or representation thereon for the designees set forth in Section 6.2(a), such Member shall be deemed immediately upon the existence of such a breach to have granted to the person or persons entitled to designate or recommend the director(s) for which such Member failed to vote, a proxy to vote its Voting Interests to ensure that such Voting Interests will be voted for such nominee. Each of the Series A Member and the Class A Member acknowledges that each proxy granted hereby, including any successive proxy if need be, is given to secure the performance of a duty and shall be irrevocable until the duty is performed. (c) Certain Resignations or Removals. -------------------------------- (i) Each of Class A Member and the Series A Member shall also have the right at any time to request, in a signed writing submitted to the Secretary of the Company, the resignation or removal of a Director originally designated or recommended by such Member. In such event, the affected Director shall immediately resign or be subject to removal by a vote of the Members, and the Members shall vote all of their Voting Interests in favor of such removal. (ii) If any Director is no longer entitled to be designated to be a Director pursuant to Section 6.2(a), such Director shall immediately resign or be subject to removal by a vote of the Members, and the Members shall vote all of their Voting Interests in favor of such removal. (iii) If the affected director shall fail to resign upon the occurrence of the events specified in Section 6.2(c)(i) or 6.2(c)(ii), then any Member shall have the right to call a special meeting of the Members or solicit written consents of the Members for the purpose of removing such director and the Members shall vote all of their Voting Interests in favor of removal. (d) Filling Vacancies. In the event of the death, removal or resignation ----------------- of any Director, any Member shall have the right to call a special meeting of Members for the purpose of electing a Director (provided that such Director shall be designated in accordance with Section 6.2(a)) to fill the vacancy created by such death, removal or resignation. Any party entitled to designate a Director to fill such vacancy that fails to do so prior to the election of a replacement by the Members hereunder may call a special meeting of Members or solicit written consents of 20

Members for the purpose of removing the Director so elected and electing such party's designee to the Board, or such party may designate a Director for election at the next annual meeting of Members to succeed the Director elected by the Members pursuant to this Section 6.2(d). In any such event, the Members shall vote all of their Voting Interests in favor of the designee of the party originally entitled to designate a Director to fill such vacancy. (e) Notices. ------- (i) The Company shall promptly give each of the Members written notice of any request by a Member for the resignation or removal of a member of the Board. (ii) Notice shall be given to each member of the Board at least 14 days prior to any meeting of the Board at which it is proposed that a vacancy on the Board be filled unless such notice shall have been waived by such member of the Board. (f) Covenant to Vote. Each of the Members shall appear in person or by ---------------- proxy at any annual or special meeting of Members for the purpose of obtaining a quorum and shall vote the Voting Interest held by such Member entitled to vote, either in person or by proxy, at any annual or special meeting of Members called for the purpose of voting on the election of Directors or by consensual action of Members with respect to the election of Directors, in favor of the election of the Directors designated in accordance with Sections 6.2(a) and 6.2(d). In addition, each Member shall appear in person or by proxy at any annual or special meeting of Members for the purpose of obtaining a quorum and shall vote their Voting Interests entitled to vote upon any other matter submitted to a vote of the Members of the Company in a manner so as to be consistent and not in conflict with, and to implement, the terms of this Agreement. (g) No Voting or Conflicting Agreements. No Member shall grant any proxy ----------------------------------- or enter into or agree to be bound by any voting trust with respect to the Voting Stock held by such Member nor shall any Member enter into any Member agreements or arrangements of any kind with any person with respect to the Voting Interests inconsistent with the provisions of this Agreement (whether or not such agreements and arrangements are with other Members of the Company that are not parties to this Agreement). No Member shall act, for any reason, as a member of a group or in concert with any other persons in connection with the acquisition, disposition or voting of the Company's Units in any manner that is inconsistent with the provisions of this Agreement. (h) Injunctive Relief. It is acknowledged that it will be impossible to ----------------- measure in money the damages that would be suffered if the parties fail to comply with any of the obligations imposed on them pursuant to this Article VI and that in the event of any such failure, an aggrieved person will be irreparably damaged and will not have an adequate remedy at law. Any such person shall, therefore, be entitled to injunctive relief, including specific performance, to enforce such obligations, and if any action shall be brought in equity to enforce any of the provisions of this Agreement, none of the parties hereto shall raise the defense that there is an adequate remedy at law. 21

(i) Terms. Each Director shall serve until the earlier of (i) such ----- Director's resignation, removal, retirement, death, or disability and (ii) the expiration of such Director's term as a Director.

Each Director shall be entitled to ------------------------- compensation for the Director's services as determined by the Board from time to time and to reimbursement for all expenses reasonably incurred by the Director in the performance of the Director's duties. (k) Indemnification. The Company shall indemnify the Directors to the --------------- fullest extent permitted by law and as set forth in Article XII. (l) Voting. Each Director shall have one vote in any decision of the ------ Board. The Directors may participate in a meeting of the Board by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear or otherwise interactively communicate with each other, and such participation shall constitute presence in person at such meeting. Any action which may be taken at a meeting of the Board may be taken without a meeting if Directors casting votes sufficient to approve such action consent thereto in writing and the Company provides notice of such action to all other Directors. (m) Meetings. A meeting of the Board shall be held at such times as called -------- by a Majority in Interest of the Members, the Class A Member, or the Series A Member. No other regular meetings of the Board of Directors are required to be held. The meetings shall be noticed, held and conducted pursuant to this Agreement. In any instance in which the approval of the Board is required under this Agreement, such approval may be obtained in any manner as permitted by the DLLCA, including without limitation by the unanimous written consent of the members of the Board. (n) Powers and Duties of Directors. Subject to the provisions of the DLLCA ------------------------------ and any limitations in this Agreement relating to actions that are required to be approved by the Board, the business and affairs of the Company shall be managed and all Company powers shall be exercised by or under the direction of the Board. Without prejudice to these general powers, and subject to the same limitations, the Board shall have the power to: (i) Select and remove all Officers, agents, and employees of the Company; prescribe any powers and duties for them that are consistent with law, with the Certificate, and with this Agreement; fix their compensation; (ii) Change the principal executive office or the principal business from one location to another; cause the Company to be qualified to do business in any other state; territory, dependency, or country and conduct business within or outside the State of California and designate any place within or outside the State of California for holding any Members' meeting or meetings, including annual meetings.

SECTION 6.3 Officers. The Officers of the Company shall be -------- Chairman of the Board (the "Chairman"), President, Treasurer and Secretary. The Company may also have, at the discretion of the Board, such other Officers as may be appointed in accordance with this Agreement. Any number of offices may be held by the same person. (a) Chairman of the Board. The Board shall elect a Chairman, who shall --------------------- preside, if present, at Board meetings and shall exercise and perform such other powers and duties as may be assigned from time to time by the Board.

The Members acknowledge the status of the Company as a limited liability company formed under the DLLCA. ARTICLE X -- CAPITAL ACCOUNTS AND ALLOCATIONS -------------------------------- SECTION 10.1 Maintenance. Each Member agrees that a single capital ----------- account (each a "Capital Account") shall be established and maintained for each Member and shall be credited, charged, and otherwise adjusted as provided in this Article X and as required by the regulations promulgated under (S)704(b) of the Code (the "(S)704(b) Regulations").

The provisions of this Section 10.1 relating to maintenance of Capital Accounts have been included in this Agreement to comply with Section 704(b) of the Code and the 704(b) Regulations and shall be interpreted and applied in a manner consistent with those provisions. SECTION 10.2 Allocation of Net Profits and Net Losses. Except as ---------------------------------------- otherwise provided in this Agreement, items of income, gain, loss and deductions of the Company shall be allocated among the Members in pro rata in accordance with their respective Percentage Interests (and as if the Series A Preferred Units were fully converted). SECTION 10.3 Special Allocations. ------------------- (a) Subject to the exceptions stated in Treasury Regulation Sections 1.704-2(f) and 1.704-2(i)(4), if there is a net decrease in Company Minimum Gain or Member Nonrecourse Debt Minimum Gain during a Fiscal Year, each Member will be specially allocated items of income and gain for Capital Account purposes for such year (and, if necessary, for subsequent years) in an amount equal to such Member's share of such net decrease during such year (which share of such net decrease will be determined under Treasury Regulations Sections 1.704-2(g)(2) and 1.704-2(i)(5)). The Members intend that this Section 10.3(a) comply with the minimum gain chargeback requirements in such Treasury Regulations Sections and will be interpreted consistently therewith. (b) Any Nonrecourse Deductions will be allocated to the Members in proportion to their Percentage Interest (and as if the Series A Preferred Units were fully converted). (c) Any Member Nonrecourse Deductions will be allocated to the Members as provided in Treasury Regulation Section 1.704-2(i)(1). (d) If any Member unexpectedly receives any adjustments, allocations or distributions described in Treasury Regulations Sections 1.704- 1(b)(2)(ii)(d)(4),(5) or (6) (modified as appropriate, by Treasury Regulations Section 1.704-2(g)(1) and 1.704-2(i)(5)), items of Company income and gain for Capital Account purposes for such Fiscal Year will be specially allocated to the Member in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations, any deficit balance in the Adjusted Capital Account of the Member as quickly as possible, provided, that an allocation pursuant to this Section 10.3(d) will be made if and only to the extent that the Member would have an Adjusted Capital Account deficit after 33

all other allocations provided for in this Agreement have been tentatively made as if this Section 10.3(d) were not in the Agreement. (e) Notwithstanding the foregoing provisions of Section 10.2 and Section 10.3, a Member will not be allocated any item of loss or deduction if such allocation would cause or increase a deficit balance in such Member's Adjusted Capital Account. Instead, such item of loss or deduction will be allocated to the Members entitled to receive such allocation under Treasury Regulation Section 1.704 in proportion to their respective Percentage Interest. (f) To the extent any adjustment to the adjusted tax basis of any Company asset pursuant to Code Section 734(b) or Code Section 743(b) is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, appropriate adjustments to the Capital Accounts shall be made. (g) The allocations stated in Sections 10.3(a) through (f) above (the "Regulatory Allocations"), are intended to comply with certain requirements of the Treasury Regulations. Notwithstanding the provisions of Section 10.3, the Regulatory Allocations can be taken into account in allocating other items of income, gain, loss and deduction among the Members so that, to the extent possible, the net amount of such allocations of other items and the Regulatory Allocations to each Member will be equal to the net amount that would have been allocated to each such Member if the Regulatory Allocations had not occurred. SECTION 10.4 Tax Allocations. --------------- (a) All items of income, gain, loss or deduction for federal, state and local income tax purposes will be allocated in the same manner as the corresponding "book" items are allocated under Sections 10.2, 10.3 or 10.4; provided, however, in the case of any Company asset the Gross Asset Value of which differs from its adjusted tax basis for federal income tax purposes, income, gain, loss and deduction with respect to such asset will, solely for tax purposes, be allocated among the Members so as to take account of any variation between the adjusted basis of such asset for federal income tax purposes and its Gross Asset Value in accordance with the principles of Sections 704(b) and 704(c) of the Code (in any permissible manner determined by the Board). (b) Any elections or other decisions relating to the foregoing tax allocations will be made by the Board in any manner that reasonably reflects the purpose and intention of this Agreement. Allocations pursuant to this Section 10.4 are solely for tax purposes and will not affect the computation of any Member's Capital Account, except as otherwise required under the Code. SECTION 10.5 Allocation Between Assignor and Assignee. The portion ---------------------------------------- of the income, gain, losses and deductions of the Company for any Fiscal Year during which an Interest is assigned by a Member (or by an assignee or successor in interest to a Member), that is allocable with respect to such Interest will be apportioned between the assignor and the assignee of the Interest on whatever reasonable, consistently applied basis selected by the Board and permitted by the applicable Treasury Regulations under Section 706 of the Code. 34

SECTION 10.6 Tax Reporting. The Members are aware of the income tax ------------- consequences of the allocations made by this Article X and hereby agree to be bound by the provisions of this Article X in reporting their Company income and loss for income tax purposes. SECTION 10.7 Profit Shares. Solely for purposes of determining a ------------- Member's proportionate share of the Company's "excess nonrecourse liabilities," as defined in Treasury Regulation Section 1.752-3(a), the Members' interests in Company profits will be deemed to be in proportion to their relative Capital Contributions. ARTICLE XI -- DISTRIBUTIONS ------------- SECTION 11.1 Distributions. Distributions, other than during a ------------- Liquidation, shall, from time to time until Dissolution be made in such amounts and at such times, if any, as the Board shall determine. Distributions shall be made to the Members pro rata in accordance with their respective Percentage Interests (and including the Series A Member pursuant to Section 5.1). SECTION 11.2 Withholding. ----------- (a) If required by the Code or by state, local, or foreign law, the Company shall withhold any required amount from Distributions to a Member for payment to the appropriate taxing authority. Any amount so withheld from a Member shall be treated as a Distribution by the Company to such Member. Each Member agrees to timely file any document that is required by any taxing authority in order to avoid or reduce any withholding obligation that would otherwise be imposed on the Company. (b) To the extent any amount that is required to be withheld with respect to a Member and paid over to an appropriate taxing authority exceeds the amounts distributed or deemed distributed to such Member in respect of such withholding, such excess amounts paid to the taxing authority in respect of such withholding shall be treated as a loan to such Member that is payable on demand. ARTICLE XII -- INDEMNIFICATION --------------- SECTION 12.1 Indemnification by Company.

Notwithstanding the foregoing, no indemnification shall be provided by the Company with respect to any Indemnification Obligation that resulted from action or inaction of such Indemnified Party that, in each case, constituted gross negligence, willful misconduct, a breach of the Indemnified Party's fiduciary duty or duty of loyalty to the Company, or an act (a) that was not in good faith, (b) that involved a knowing violation of law, or (c) from which the Indemnified Party derived an improper personal benefit.

The termination of a proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere, or its equivalent, shall not, of itself, create a presumption that such Indemnification Obligation resulted from the gross negligence or willful misconduct of such Indemnified Party. Expenses (including reasonable legal and other professional fees and disbursements) incurred in any proceeding shall be paid by the Company, as incurred, in advance of the final disposition of such proceeding upon receipt of an undertaking by or on behalf of such Indemnified Party to repay such amount if it shall ultimately be determined that such Indemnified Party is not entitled to be indemnified by the Company as authorized hereunder. SECTION 12.2 Indemnification Not Exclusive. The indemnification ----------------------------- provided by Section 12.1 shall not be deemed to be exclusive of any other rights to which each Indemnified Party may be entitled under any agreement, or as a matter of law, or otherwise, both as to action in such Indemnified Party's official capacity and to action in another capacity, and shall continue as to such Indemnified Party who has ceased to have an official capacity for acts or omissions during such official capacity or otherwise when acting at the request of the Company, or any Person granted authority thereby, and shall inure to the benefit of the heirs, successors, and administrators of such Indemnified Party.

The Company ---------------------------------------- shall have the power but not the obligation to purchase and maintain insurance on behalf of each Indemnified Party, at the expense of the Company, against any liability which may be asserted against or incurred by him in any such capacity, whether or not the Company would have the power to indemnify the Indemnified Parties against such liability under the provisions of this Agreement. SECTION 12.4 No Agency. No Member acting solely in the capacity of --------- a Member is an agent of the Company, nor can any Member acting solely in the capacity of a Member bind the Company or execute any instrument on behalf of the Company. Accordingly, each Member shall indemnify, defend, and hold harmless each other Member and the Company from and against any and all loss, cost, expense, liability, or damage arising from or out of any claim based upon any action by such Member in contravention of the first sentence of this Section 12.4. The foregoing indemnification by a Member shall not be deemed to be exclusive 36

of any other rights to which the party indemnified thereby may be entitled under any agreement, as a matter of law, or otherwise. SECTION 12.5 Indemnification Limited by Law. Notwithstanding any of ------------------------------ the foregoing to the contrary, the provisions of this Article XII shall not be construed so as to provide for any indemnification for any liability to the extent (but only to the extent) that such indemnification would be in violation of applicable law or that such liability may not be waived, modified, or limited under applicable law, but shall be construed as to effectuate the provisions of this Article XII to the fullest extent permitted by law. SECTION 12.6 Amendment of Agreement.

It is intended that the distributions set forth in this Section 14.2(c) comply with the intention of Treasury Regulations Section 1.704-1(b)(2)(ii)(b)(2) that liquidating distributions to Members be made in accordance with positive Capital Accounts. However, if the balances in the Capital Accounts do not result in such requirement being satisfied, no change in the amounts of distributions pursuant to said Sections shall be made; rather, items of income, gains, loss, deduction, and credit shall be reallocated among the Members so as to cause the balances in the Capital Accounts to be in the amounts necessary so that, to the extent possible, such result is achieved; and (e) Notwithstanding anything in this Section 14.2 to the contrary, the Basic Technology (as defined in the Revenue Sharing Agreement dated as of September 4, 2000 between the Company and the Class A Member) is subject to a reversionary interest upon Liquidation or Dissolution of the Company and such Basic Technology shall be assigned, transferred and conveyed to the initial Class A Member upon such events prior to any other distributions made pursuant to Section 14.2(b) or (c) and shall not be deemed to be an asset of the Company for purposes of this Section 14.2. SECTION 14.3 Liquidating Reports. A report shall be submitted with ------------------- each liquidating Distribution, showing the collections, disbursements and Distributions during the period which is subsequent to any previous report.

SECTION 14.5 Deficit Capital Account. Upon a liquidation of the ----------------------- Company within the meaning of (S)1.704-1(b)(2)(ii)(g) of the Treasury Regulations, if any Member has a negative Capital Account (after giving effect to all contributions, Distributions, allocations, and 38

other adjustments for all Fiscal Years, including the Fiscal Year in which such liquidation occurs), the Member shall have no obligation to make any Capital Contribution, except as otherwise expressly required by the DLLCA, and the negative balance of any Capital Account shall not be considered a debt owed by the Member to the Company or to any other person for any purpose. SECTION 14.6 Nonrecourse to Other Members. If the assets of the ---------------------------- Company remaining after the payment or discharge of the debts and liabilities of the Company are insufficient to return any Capital Contribution of any Member, such Member shall have no recourse against any other Member. ARTICLE XV -- TRANSFER RESTRICTIONS --------------------- SECTION 15.1 Member's Obligations. If any Member (the "Transferring -------------------- Member") proposes to make a Transfer of Units, such Transferring Member shall comply with the terms and conditions of this Article XV at any time prior to a Qualified IPO. SECTION 15.2 Sale Notice. Prior to making a Transfer of Units, the ----------- Transferring Member shall give at least 60 days' prior written notice (the "Sale Notice") to the Company and any non-Transferring Member (the "Non-Transferring Member") (a) identifying (i) the type and amount of Units to be sold (the "Offered Units"), (ii) the price at which the Transferring Member proposes to Transfer the Offered Units (the "Offer Price") and (iii) the proposed closing date for the Transfer (which date shall be not less than 60 days and not more than 90 days after the date of the Sale Notice), (b) describing any other terms and conditions of such proposed Transfer, and (c) identifying each prospective transferee.

(a) If the Transferring Member does not receive any timely Co-Sale Notices with respect to the Transfer proposed in the Sale Notice, then the Transferring Member may Transfer such Offered Units on the terms and conditions set forth in the Sale Notice at any time within 30 days after expiration of the 20-day period for giving Co-Sale Notices with respect to such Transfer. Any Offered Units not Transferred by the Transferring Member during such 30-day period will again be subject to the provisions of this Section 15.3 upon subsequent Transfer. Should the Transferring Member receive one or more timely Co-Sale Notices, then the Transferring Member shall use all reasonable efforts to cause the prospective transferee(s) to agree to acquire all such additional Units on the same terms and conditions as applicable to the Offered Units. If the prospective transferee(s) is unwilling or unable to acquire all such additional Units upon such terms, then the Transferring Member may elect either to cancel such proposed Transfer or to allocate the maximum number of Units that the prospective transferee(s) is willing to purchase among the Transferring Member and each Non-Transferring Member that 39

gave timely Co-Sale Notices in the proportion of the Fully-Diluted Percentage Interests owned by each such Non-Transferring Member bears to the Fully-Diluted Percentage Interests owned by all such Non-Transferring Members (not to exceed, however, with respect to any such Non-Transferring Member, the amount of Offered Units proposed to be transferred in such Non-Transferring Member's Co-Sale Notice, as the case may be) and to consummate such Transfer on those terms. (b) Notwithstanding the provisions of this Section 15.3, the Class A Member shall be subject to Section 15.3 for the three year period after the Effective Date. After the end of such three year period, one-third of any Units held by the Class A Member at such time shall become cumulatively excluded from the provisions of Section 15.3 per year over the next three years. SECTION 15.4 Right of First Refusal. After receipt of the Sale ---------------------- Notice, each of the Company and the Non-Transferring Member (each an "ROFR Offeree") may give written notice (a "Notice of Exercise"), within the time periods and in the priority specified below, to the Transferring Member that such ROFR Offeree wishes to exercise the right to purchase at the Offer Price all but not less than all of the Offered Units. The right of the ROFR Offerees pursuant to this Section 15.4 shall terminate if the ROFR Offerees have not delivered one or more Notices of Exercise relating, in the aggregate, to all of the Offered Units within 20 days after the Company's receipt of the Sale Notice. (a) The Sale Notice shall constitute an offer to sell the Offered Units to the ROFR Offerees in the following priority: (i) the Company shall be given the first right to elect to acquire the Offered Units; and (ii) to the extent the Company fails to elect to acquire all of the Offered Units, any Non-Transferring Member may elect to acquire the Offered Units. (b) Within 20 days after receipt of the Sale Notice, the Company may elect to purchase, at the price and on the terms specified in the Sale Notice, all of the Offered Units by delivering a written notice of exercise to the Members. (c) If the Company elects not to purchase the Offered Units, the Company shall provide written notice (the "Company Notice") to the Non-Transferring Members within 20 days following the receipt of the Sale Notice that the Company has not elected to purchase all or any of the Offered Units. Within 20 days following the receipt of the Company Notice, the Non-Transferring Members shall have the right to purchase or obtain, at the price and on the terms specified in the Sale Notice, such remaining Units (the "Remaining Interests"). The Non- Transferring Members shall exercise its right to purchase or obtain the Remaining Interests by giving written notice thereof to the Transferring Member within five Business Days after receipt by the Non-Transferring Members of the Company Notice. (d) If the Offer Price, or a portion of the Offer Price, involves consideration other than cash, the ROFR Offerees shall have the right to purchase the Offered Units for a cash amount equal to the sum of the portion of such consideration which is cash plus the Cash Value (as defined below) of the non-cash consideration. For purposes of this Section 15.4, "Cash Value" shall mean, in the case of securities which are quoted on any national securities exchange, cash in an amount equal to the average of the last reported sales price on such 40

exchange for such securities for the five trading days prior to the date of the Sale Notice and, in the case of securities or other property for which there is no such readily available market price, an amount equal to the fair market value of such securities or property as determined in good faith by the Board. (e) If the ROFR Offerees exercise their rights to purchase a portion of the Offered Units in accordance with Section 15.4, then the Transferring Member must sell such portion of the Offered Units to such party or parties. (f) At the closing of the purchase of the Offered Units, the Transferring Member shall deliver to the applicable ROFR Offerees certificates evidencing the Offered Units, duly endorsed, or accompanied by written instruments of transfer in form reasonably satisfactory to the applicable ROFR Offerees, duly executed by the Transferring Member, free and clear of any Encumbrances, against payment of the purchase price therefor in cash. The closing date shall be the date specified by the Transferring Member in the Sale Notice or such other date as is mutually agreed upon by the appropriate parties. (g) The Transferring Member may, during the 180-day period following the expiration of the period in which a notice of exercise may be given, sell or enter into an agreement to sell the Offered Units to any person or persons at a price not less than, and upon terms no more favorable to the offeree than, those specified in the Sales Notice. If the Transferring Member does not enter into an agreement for the sale of the Offered Units within such period, or if such agreement is not consummated within 90 days of the execution thereof, the right provided in this Section 15.4 shall be deemed to be revived and such Offered Units shall not be offered unless first reoffered to the Company and the Non- Transferring Members in accordance with this Article XV. SECTION 15.5 Securities Act Compliance. No Units may be Transferred ------------------------- by a Member (other than pursuant to an effective registration statement under the Securities Act) unless such Member first delivers to the Company an opinion of counsel, which opinion and counsel shall be reasonably satisfactory to the Company, to the effect that such Transfer is not required to be registered under the Securities Act. SECTION 15.6 Permitted Transfers. Notwithstanding Sections 15.3 and ------------------- 15.4, a Member may Transfer or cause to be transferred all or any portion of such Member's Units: (i) to any person with the consent of the Company (including, but not limited to, a sale by public offering); (ii) to any person in the Family Group of the Member; (iii) by will or by the laws of descent and distribution; (iv) by pledge to secure a bona fide loan made by a lending institution; and (v) as part of any combination, exchange, merger, consolidation, redemption, retirement, recapitalization, or reorganization generally affecting the Units (or any class or series of Units) (each of (i) through (v), a "Permitted Transfer"). SECTION 15.7 Transferees Bound by Agreement. Subject to compliance ------------------------------ with the other provisions of this Article XV, a Member may Transfer any Units held by such Member in accordance with applicable law; provided, however, that the transferee of such security shall be bound by all the terms and provisions of this Agreement and no Transfer shall be valid or a 41

permitted transfer unless such transferee consents in writing to be bound by the terms of this Agreement applicable to Members. SECTION 15.8 Transfers in Violation of Agreement. Any Transfer or ----------------------------------- attempted Transfer of any Units in violation of any provision of this Agreement shall be void, and the Company shall not record such Transfer on its books nor treat any purported transferee of such Units as the owner of such Units for any purpose. SECTION 15.9 Series A Member's Drag Along Right. In connection with ---------------------------------- a sale to a third party by the Series A Member of all Units owned by the Series A Member, at the Series A Member's election and in its sole discretion, the Series A Member shall have the right to cause all other Members to sell their Units in such sale to such third party upon the same terms and conditions as the sale by the Series A Member to such third party; provided, that such other Members receive all cash consideration and are not required to make representations and warranties other than regarding their authority to transfer their Units and the lack of Encumbrances with respect to the Units. ARTICLE XVI -- REGISTRATION RIGHTS ------------------- SECTION 16.1 Request for Registration. ------------------------ (a) If the Company shall receive at any time after six months after the effective date of the first registration statement for a public offering of securities of the Company (other than a registration statement relating either to the sale of securities to employees of the Company pursuant to a stock option, stock purchase or similar plan or a Rule 145 transaction), a written request from Holders of Registrable Securities of 5% or more of the Registrable Securities then outstanding (provided, that the Class A Member may submit a written request for less than 5% of the Registrable Securities is such amount constitutes all of Registrable Securities of the Class A Member) ("Initiating Holders"), requesting that the Company file a registration statement under the Securities Act covering the registration of a portion of the Registrable Securities then outstanding, then, provided, that, the Registrable Securities held by the Initiating Holders have an anticipated aggregate public offering amount of not less than $7,500,000, the Company shall: (i) within 15 days of the receipt thereof, give written notice of such request to all Holders of Registrable Securities; and (ii) effect as soon as practicable, and in any event within 90 days of the receipt of such request, the registration under the Securities Act of all Registrable Securities which the Holders of Registrable Securities request to be registered, subject to the limitations of subsection 16.1.(b), within 15 days of the mailing of such notice by the Company. (b) If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to Section 16.1(a) and the Company shall include such information in the written notice referred to in subsection 16.1(a). The underwriter will be selected by the Company and shall be reasonably acceptable to a majority in interest of the Initiating Holders. 42

In such event, the right of any Holder of Registrable Securities to include securities in such registration shall be conditioned upon the participation in such underwriting by such Holder of Registrable Securities and the inclusion of the securities of such Holder of Registrable Securities in the underwriting (unless otherwise mutually agreed by a majority in interest of the Initiating Holders and such Holder of Registrable Securities) to the extent provided herein. All Holders of Registrable Securities proposing to distribute their securities through such underwriting shall (together with the Company as provided in subsection 16.2(b)) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting. Notwithstanding any other provision of this section 16.1(b), if the underwriter advises the Initiating Holders in writing that marketing factors require a limitation of the number of securities to be underwritten, then the Company shall so advise all Holders of Registrable Securities and other holders of securities subject to registration rights which would otherwise be underwritten pursuant hereto, and the number of securities that may be included in the underwriting on behalf of each Holder of Registrable Securities shall be allocated on a pro-rata basis among the selling holders according to the total number of securities held by each such selling holder and entitled to inclusion therein on the basis of a registration rights agreement with the Company; provided, however, that the number of Registrable Securities to be included in such underwriting shall not be reduced unless all other securities are first entirely excluded from the underwriting and registration. For purposes of allocating securities to be included in any offering, for any selling holder which is a partnership or Company, the "affiliates" (as defined in Rule 405 under the Securities Act), partners, retired partners and shareholders of such holder (and in the case of a partnership, any affiliated partnerships), or the estates and family members of any such partners and retired partners and any trusts for the benefit of any of the foregoing persons shall be deemed to be a single "selling holder," and any pro-rata reduction with respect to such "selling holder" shall be based upon the aggregate amount of Units carrying registration rights owned by all entities and individuals included in such "selling holder," as defined in this sentence. To facilitate the allocation of Units in accordance with the above provisions, the Company may round the number of Units allocated to any Holder of Registrable Securities to the nearest 100 Units. (c) Notwithstanding the foregoing, if the Company shall furnish to Holders of Registrable Securities requesting a registration statement pursuant to this Section 16.1, a certificate signed by the President stating that in the good faith judgment of the Board of the Company, it would be seriously detrimental to the Company and its shareholders for such registration statement to be filed and it is therefore essential to defer the filing of such registration statement, the Company shall have the right to defer taking action with respect to such filing for a period of not more than 90 days after receipt of the request of the Initiating Holders; provided, however, that the Company may not utilize this right more than twice in any twelve-month period. (d) In addition, the Company shall not be obligated to effect, or to take any action to effect, any registration pursuant to this Section 16.1: (i) after the Company has effected two registrations pursuant to this Section 16.1 and such registrations have been declared or ordered effective; provided that, a registration shall not count against this limitation in the event the number of Registrable 43

Securities to be include in the registration has been reduced by more than one- third of the original number of Registrable Securities for which registration was sought; (ii) during the period starting with the date 60 days prior to the Company's good faith estimate of the date of filing of, and ending on a date 180 days after the effective date of, (x) a previous registration subject to this Section 16.1, (y) the Company's initial registered offering of its securities to the general public (other than a registration statement relating to either the sale of securities to employees of the Company pursuant to an option or similar plan or an Rule 145 transaction) or (z) a previous registration subject to Section 16.2 of this Agreement; provided that, the Company is actively employing in good faith all reasonable efforts to cause such registration statement to become effective; (iii) In any particular jurisdiction in which the Company would be required to execute a general consent to service of process, unless the Company is already subject to service in such jurisdiction and except as required by the Securities Act; or (iv) If the Initiating Holders propose to dispose of Registrable Securities that may be immediately registered on Form S-3 pursuant to a request made pursuant to Section 16.3 below. SECTION 16.2 Company Registration. -------------------- (a) If (but without any obligation to do so) the Company proposes to register (including for this purpose a registration effected by the Company for holders other than the Holders of Registrable Securities) any of its securities under the Securities Act in connection with the public offering of such securities solely for cash (other than a registration relating solely to the sale of securities to participants in a Company option plan, a registration pursuant to a Rule 145 transaction, a registration on any form which does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities or a registration in which the only Units being registered is Units issuable upon conversion of debt securities which are also being registered), the Company shall, at such time, promptly give each Holder written notice of such registration. Upon the written request of each Holder given within fifteen (15) days after mailing of such notice by the Company, the Company shall, subject to the provisions of paragraph 16.2(b) below, cause to be registered under the Securities Act all of the Registrable Securities that each such Holder has requested to be registered. (b) In connection with any offering involving an underwriting of securities, the Company shall not be required under this Section 16.2 to include any of the securities of such Holders of Registrable Securities in such underwriting unless they accept the terms of the underwriting as agreed upon between the Company and the underwriters selected by it (or by other persons entitled to select the underwriters), and then only in such quantity as the underwriters determine in their sole discretion will not jeopardize the success of the offering by the Company. If the total amount of securities, including Registrable Securities, requested by holders to be included in such offering exceeds the amount of securities sold other than by the Company that the underwriters determine in their sole discretion is compatible with the success 44

of the offering, then the Company shall be required to include in the offering only that number of such securities, including Registrable Securities, which the underwriters determine in their sole discretion will not jeopardize the success of the offering, but in no event shall (i) the amount of securities of the selling Holders of Registrable Securities included in the offering be reduced below twenty-five percent (25%) of the total amount of securities included in such offering, unless such offering is the initial public offering of the Company's securities, in which case the Holders of Registrable Securities may be excluded entirely if the underwriters make the determination described above and no other holder's securities are included or (ii) notwithstanding (i) above, any Units being sold by a holder exercising a demand registration right pursuant to Section 16.1 be excluded from such offering. Allocation of securities to be sold in any such offering shall be made on a pro-rata basis among the selling holders according to the total number of securities held by each such selling holder and entitled to inclusion therein on the basis of a registration rights agreement with the Company; provided, however, that the number of Units of Registrable Securities to be included in such offering shall not be reduced unless all other securities (other than shares to be issued by the Company) are first entirely excluded from the offering. For purposes of allocation of securities to be included in any offering, for any selling holder which is a partnership or Company, the "affiliates" (as defined in Rule 405 under the Securities Act), partners, retired partners and holders of such holder (and in the case of a partnership, any affiliated partnerships), or the estates and family members of any such partners and retired partners and any trusts for the benefit of any of the foregoing persons shall be deemed to be a single "selling holder," and any pro-rata reduction with respect to such "selling holder" shall be based upon the aggregate amount of Units carrying registration rights owned by all entities and individuals included in such "selling holder," as defined in this sentence. SECTION 16.3 Form S-3 Registration. In case the Company shall --------------------- receive from any Holder or Holders of Registrable Securities a written request or requests that the Company effect a registration on Form S-3 and any related qualification or compliance with respect to all or a part of the Registrable Securities owned by such Holder or Holders of Registrable Securities, the Company will: (a) promptly give written notice of the proposed registration, and any related qualification or compliance, to all other Holders of Registrable Securities; (b) as soon as practicable, effect such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of the Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holder or Holders of Registrable Securities joining in such request as are specified in a written request given within 15 days after receipt of such written notice from the Company; provided, however, that the Company shall not be obligated to effect any such registration, qualification or compliance, pursuant to this Section 16.3: (1) if the Registrable Securities requested by all Holders of Registrable Securities to be registered pursuant to this Section 16.3 have an anticipated aggregate offering price to the public (before deducting any underwriter discounts, concessions or commissions) of less than $750,000; (2) if Form S-3 is not available for such offering by the Holders of Registrable Securities; (3) if the Company shall furnish to the Holders of Registrable Securities a certificate signed by the President of the Company stating that in the good faith judgment of the Board of 45

(e) In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter of such offering. Each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement. (f) Notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing. (g) Cause all such Registrable Securities registered pursuant hereunder to be listed on each securities exchange on which similar securities issued by the Company are then listed. (h) Provide a transfer agent and registrar for all Registrable Securities registered pursuant hereunder and a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration. (i) In the event of any underwritten public offering, cooperate with the selling Holders of Registrable Securities, the underwriters participating in the offering and their counsel in any due diligence investigation reasonably requested by the selling Holders of Registrable Securities or the underwriters in connection therewith, and participate, to the extent reasonably requested by the managing underwriter for the offering or the selling Holder, in efforts to sell the Registrable Securities under the offering (including, without limitation, participating in "roadshow" meetings with prospective investors) that would be customary for underwritten primary offerings of a comparable amount of equity securities by the Company. SECTION 16.5 Furnish Information. ------------------- (a) It shall be a condition precedent to the obligations of the Company to take any action pursuant to this Article XVI with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of disposition of such Securities as shall be required to effect the registration of such Holder's Registrable Securities. (b) The Company shall have no obligation with respect to any registration requested pursuant to Section 16.1 or Section 16.3 if, due to the operation of subsection 16.5(a), the number of Units or the anticipated aggregate offering price of the Registrable Securities to be included in the registration does not equal or exceed the number of Units or the anticipated aggregate offering price required to originally trigger the Company's obligation to initiate such registration as specified in subsection 16.1(a) or subsection 16.3(b), whichever is applicable. SECTION 16.6 Expenses of Demand, Company or S-3 Registration. All ------------------------------------------------ expenses (exclusive of underwriting discounts and commissions and transfer taxes) incurred in connection with registrations, filings or qualifications pursuant to this Article XVI including 47

SECTION 16.7 Delay of Registration. No Holder shall have any right ---------------------- to obtain or seek an injunction restraining or otherwise delaying any such registration as the result of any controversy that might arise with respect to the interpretation or implementation of this Article XVI. SECTION 16.8 Indemnification. In the event any Registrable --------------- Securities are included in a registration statement under this Article XVI: (a) To the extent permitted by law, the Company will indemnify and hold harmless each Holder, the constituent partners and members, or officers and directors of each Holder, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a "Violation"): (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law; and the Company will pay to each such Holder, underwriter or controlling person any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability, or action, as such expenses are incurred; provided, however, that the indemnity agreement contained in this subsection 16.8(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case for any such loss, claim, damage, liability, or action to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by any such Holder, underwriter or controlling person. (b) To the extent permitted by law, each selling Holder will indemnify and hold harmless the Company, each of its directors, each of its officers who has signed the registration statement, each person, if any, who controls the Company within the meaning of the Securities Act, any underwriter, any other Holder selling securities in such registration statement and any controlling person of any such underwriter or other Holder, severally but not jointly, against any losses, claims, damages, or liabilities (joint or several) to which any of the foregoing persons may become subject, under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereto) arise out of or 48

are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in connection with such registration; and each such Holder will pay any legal or other expenses reasonably incurred by any person intended to be indemnified pursuant to this subsection 16.8(b), in connection with investigating or defending any such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in this subsection 16.8(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; provided, that, in no event shall Holder's cumulative, aggregate liability under this subsection 16.8(b), under Section 16.8(d), or under such sections together, exceed the net proceeds received by such Holder from the offering out of which such Violation arises. (c) Promptly after receipt by an indemnified party under this Section 16.8 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 16.8, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with one counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified parties which may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the indemnified party under this Section 16.8 unless the failure to deliver notice is materially prejudicial to its ability to defend such action. Any omission to so deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 16.8. (d) If the indemnification provided for in this Section 16.8 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage, or expense referred to herein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage, or expense in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand, and of the indemnified party on the other, in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties' relative intent, 49

knowledge, access to information, and opportunity to correct or prevent such statement or omission. (e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control. (f) The obligations of the Company and Holders of Registrable Securities under this Section 16.8 shall survive the completion of any offering of Registrable Securities in a registration statement under this Article XVI, and otherwise. SECTION 16.9 Reports under the Exchange Act. With a view to making ------------------------------ available to the Holders of Registrable Securities the benefits of Rule 144 promulgated under the Securities Act and any other rule or regulation of the Commission that may at any time permit a Holder to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the Company agrees to: (a) make and keep public information available, as those terms are understood and defined in Rule 144, at all times after 90 days after the effective date of the first registration statement filed by the Company for the offering of its securities to the general public; (b) take such action, including the voluntary registration of its securities under Section 12 of the Exchange Act, as is necessary to enable the Holders of Registrable Securities to utilize Form S-3 for the sale of their Registrable Securities, such action to be taken as soon as practicable after the end of the fiscal year in which the first registration statement filed by the Company for the offering of its securities to the general public is declared effective; (c) file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and (d) furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request (i) a written statement by the Company that it has complied with the reporting requirements of Rule 144 (at any time after 90 days after the effective date of the first registration statement filed by the Company), the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form S-3 (at any time after it so qualifies), (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the Commission which permits the selling of any such securities without registration or pursuant to such form. SECTION 16.10 Assignment of Registration Rights. The rights to cause --------------------------------- the Company to register Registrable Securities pursuant to this Article XVI may be assigned (but only with all related obligations) by a Holder to, (i) in the case of any Holder that is a partnership, limited liability company or Company, any current and former constituent partners, 50

members, holders, affiliate funds and affiliates of that Holder, or (ii) in the case of any Holder, (x) a transferee or assignee of such securities who, after such assignment or transfer, holds at least 1% of the Fully Diluted Percentage Interest at the time of the transfer as appropriately adjusted for all splits, dividends, combinations, reclassifications and other like transactions of the Registrable Securities originally held by such transferring Holder, or all of such transferring Holder's Units if a lesser amount is transferred, (y) a transferee or assignee who is a spouse, lineal descendant, father, mother, brother or sister (each, a "Family Member") of Holder or (z) or to a trust, the ------------- beneficiaries of which are exclusively the Holder and/or Family Members, provided, in each case, that: (a) the Company is, within a reasonable time after - -------- ---- such transfer, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned; (b) such transferee or assignee agrees in writing to be bound by and subject to the terms and conditions of this Agreement, including without limitation the provisions of Section 16.11 below; and (c) such assignment shall be effective only if immediately following such transfer the further disposition of such securities by the transferee or assignee is restricted under the Securities Act. For the purposes of determining the number of Units of Registrable Securities held by a transferee or assignee of a holder of Registrable Securities, the holdings of "affiliates" (as defined in Rule 405 under the Securities Act) of such holder, affiliated partnerships, constituent or retired partners of such partnerships (as well as Family Members of such partners or spouses who acquire Registrable Securities by gift, will or intestate succession) shall be aggregated together and with such partnership and its affiliated partnerships and other entities; provided, that, all assignees and transferees who would not qualify individually for assignment of registration rights shall have a single attorney-in-fact for the purpose of exercising any rights, receiving notices or taking any action under this Section 16.10. SECTION 16.11 "Market Stand-Off" Agreement. Each Holder hereby ---------------------------- agrees that, during the period of duration specified by the Company and an underwriter of securities of the Company, following the effective date of the registration statement of the Company filed under the Securities Act relating to its initial public offering, it shall not, to the extent requested by the Company and such underwriter, directly or indirectly sell, offer to sell, contract to sell (including, without limitation, any short sale), grant any option to purchase or otherwise transfer or dispose of (other than to donees who agree to be similarly bound) any securities of the Company held by it at any time during such period except securities included in such registration; provided, however, that: (a) the Company uses its best efforts to insure that officers and directors of the Company enter into similar agreements; (b) the Company uses its best efforts to obtain from persons who hold greater than five percent (5%) of the Company's Units, a lock-up agreement similar to that set forth in this Section 16.11; and (c) such market stand-off time period shall not exceed 180 days. Each Holder of Registrable Securities agrees to provide to the other underwriters of any public offering such further agreements as such underwriter may reasonably request in connection with 51

this market stand-off agreement, provided that the terms of such agreements are substantially consistent with the provisions of this Section 16.11. In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to the Registrable Securities of each Holder (and the securities of every other person subject to the foregoing restriction) until the end of such period. Notwithstanding the foregoing, the obligations described in this Section 16.11 shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms which may be promulgated in the future, or a registration relating solely to a Rule 145 transaction. SECTION 16.12 Termination of Registration Rights. The right of any ---------------------------------- Holder of Registrable Securities to request registration or to include Registrable Securities in any registration pursuant to this Article XVI shall terminate upon the earlier of (i) the date which is five years after the date immediately prior to the closing of a Qualified IPO, or (ii) such date as a public trading market shall exist for the Company's securities and all Registrable Securities beneficially owned and subject to Rule 144 aggregation by such Holder of Registrable Securities may immediately be sold under Rule 144 (without regard to Rule 144(k)) during any 90-day period, provided that such Holder is not then an "affiliate" of the Company within the meaning of Rule 144 and such Holder owns less than 1% of the Units. SECTION 16.13 Limitations on Subsequent Registration Rights. From --------------------------------------------- and after the date of this Agreement, the Company shall not, without the prior written consent of Amerigon, enter into any agreement with any existing Holder or prospective holder of Securities of the Company granting registration rights with respect to such Securities, unless under the terms of such agreement, such holder or prospective holder may include such securities in any such registration only to the extent that the inclusion of his securities will not reduce the amount of the Registrable Securities of the Holders of Registrable Securities which is included. ARTICLE XVII -- GENERAL PROVISIONS ----------------- ------------------ SECTION 17.1 Amendment.

Exhibit A EXHIBIT B Milestones ---------- Below are the broad milestones that, if achieved by January 2003, (1) demonstrate significant advancement in thermoelectric technology and (2) represent an application with revenue potential that is a multiple of the initial $2,000,000 capital investment in BSST. 1. Demonstrate a minimum of 30% improvement in Coefficient of Performance in cooling, when compared to best practice thermoelectric systems from Ferrotec, Marlow and Melcor (each recognized as a leader in thermoelectrics) as of January 2001 ("Base Time"). A. The improvement shall have a demonstrated theoretical basis and exhibit mechanical differences when compared to Base Time devices that cause the performance change. B. The improvement shall be demonstrated with both systems employing thermoelectric materials with the same Z (thermoelectric coefficient of performance) and at the same temperature change, ambient temperature and cooling power output. 2. Construct and demonstrate a breadboard power generator that when used in a co-generation cycle, has 30% greater thermodynamic efficiency than thermoelectric power generators as of Base Time, and has 30% less waste heat flow to the cold side when used as a stand-alone device. A. Device shall produce 1000 watts power minimum from a heat source maintained at 475C and a cold side maintained at 50C, so as to approximate the operating conditions of a heat source such as an automobile catalytic converter. B. The improvement shall be demonstrated with both systems employing thermoelectric materials with the same Z (thermoelectric coefficient of performance) and at the same temperature change, ambient temperature and electrical power output. The Board of Directors shall determine if the Milestones have been met, and may use experts in thermodynamics to independently verify the experimental results. B-1
