Pursuant to the terms of a First Amendment to Investors' Rights Agreement executed in connection with the Credit Agreement and the Investors' Rights Agreement dated as of June 8, 1999 (collectively, the "Amended Rights Agreement"), Big Star, Big Beaver and Westar II, respectively, will have certain rights to register for resale pursuant to the Securities Act of 1933, as amended, any shares of Issuer Class A Common Stock received by Big Star upon the exercise of the Conversion Right or the Bridge Loan Warrant, or received by Big Beaver or Westar II, upon the exercise of the contingent warrants or conversion of the Issuer Series A Preferred Stock held by Big Beaver and by Westar II. The Amended Rights Agreement also provides Big Beaver and Westar II with a right of first refusal to participate in future sales of equity securities by the Issuer, subject to the terms, conditions and limitations provided in the Rights Agreement. Other than as described above, no Reporting Person has any plans or proposals which relate to, or may result in, any of the matters listed in Items 4(a)-(j) of Schedule 13D. The foregoing summary of the Credit Agreement, the Promissory Note, the Bridge Loan Warrant and the Amended Rights Agreement is qualified in its entirety reference to the copies of such documents included as exhibits to the First Amendment and/or this Amendment No. 2 to Schedule 13D and incorporated herein by their entirety by this reference. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER. (a) - (b) According to the Issuer's representation in connection with the Credit Agreement, there were 1,914,089 shares of Issuer Common Stock outstanding as of March 16, 2000. As of March 16, 2000, the conversion right provides Big Star the right to convert the Promissory Note into 79,617 shares of Issuer Class A Common Stock and the Bridge Loan Warrant provides Big Star the right to purchase 7,961 shares of Issuer Class A Common Stock, and in addition, Westar II and Big Beaver each owns 4,500 shares of Series A Preferred Stock which are currently convertible into 2,686,567 shares of Issuer Class A Common Stock representing in the aggregate approximately 74.05% of the outstanding shares of Issuer Class A Common Stock (which together with the 40,000 shares owned by George L. Argyros as discussed below, represents in the aggregate approximately 74.59% of the outstanding shares of Issues Class A Common Stock). Further, Westar II and Big Beaver each owns Contingent Warrants which are exercisable for up to 614,787 shares (of which 70,224 are not currently subject to exercise) of Issuer Class A Common Stock. The Contingent Warrants, however, are exercisable only upon the exercise of certain other outstanding warrants to purchase Issuer Common Stock and only for that number of shares equal to 36.9% of the shares purchased under such other warrants. The purpose of the Contingent Warrants is to provide Westar II and Big

Beaver with anti-dilution protection in the event that other outstanding warrants to purchase Issuer Class A Common Stock are exercised. Consequently, the exercise of the Contingent Warrants would not result in either such investor owning more than 37.02% of the outstanding Issuer Class A Common Stock or in the investors together owning more than 74.59% of the outstanding Issuer Class A Common Stock. The Reporting Persons disclaim beneficial ownership of the shares underlying the Contingent Warrants until such time as such shares are purchased upon the exercise of such Contingent Warrants. Due to the controlling interest of George Argyros in Westar II and its controlling entities, and the controlling interest of Thomas Wheeler in Big Beaver and its controlling entities, Mr. Argyros and Mr. Wheeler may be deemed to share the power to vote and dispose of (and therefore be the beneficial owners of) the shares issuable upon conversion of the Promissory Note and exercise of the Bridge Loan Warrant by Big Star, and upon conversion of the Series A Preferred Stock and the exercise of the Contingent Warrants held by their respective affiliates. In addition, as the managing member of Westar II, Westar Associates may be deemed to be the beneficial owner of the shares held by Westar II. George Argyros and Westar Associates disclaim beneficial ownership of (i) all shares of Series A Preferred Stock, Contingent Warrants and shares of Issuer Common Stock issuable upon conversion or exercise thereof which are held by Big Beaver, (ii) the Bridge Loan Warrant and all shares of Issuer Common Stock issuable upon conversion or exercise of the Conversion Right under the Credit Agreement or of the Bridge Loan Warrant, except to the extent of their interests in Big Star, and (iii) all shares of Series A Preferred Stock, Contingent Warrants and shares of Issuer Common Stock issuable upon conversion or exercise thereof which are held by Westar II, except to the extent of their respective interests in Westar II. Westar II disclaims beneficial ownership of (i) all shares of Series A Preferred Stock, Contingent Warrants and shares of Issuer Class A Common Stock issuable upon conversion or exercise thereof, which are held by Big Beaver, and (ii) the Bridge Loan Warrant and all shares of Issuer Class A Common Stock issuable upon conversion or exercise of the Conversion Right under the Credit Agreement or of the Bridge Loan Warrant, except to the extent of its interests in Big Star. Thomas Wheeler disclaims beneficial ownership of (i) all shares of Series A Preferred Stock, Contingent Warrants and shares of Issuer Common Stock issuable upon conversion or exercise thereof which are held by Westar II, (ii) the Bridge Loan Warrant and all shares of Issuer Common Stock issuable upon conversion or exercise of the Conversion Right under the Credit Agreement or of the Bridge Loan Warrant, except to the extent of his interests in Big Star, and (iii) all shares of Series A Preferred Stock, Contingent Warrants and shares of Issuer Common Stock issuable upon conversion or exercise thereof which are held by Big Beaver, except to the extent of his interests in Big Beaver. Big Beaver disclaims beneficial ownership of all shares of Series A Preferred Stock, Contingent Warrants and shares of Issuer Common Stock issuable upon conversion or exercise thereof which are held by Westar II and (ii) the Bridge Loan Warrant and all shares of Issuer Class A Common Stock issuable upon conversion or exercise of the Conversion Right under the Credit Agreement or of the Bridge Loan Warrant, except to the extent of its interests in Big Star. George Argyros owns 40,000 shares of Issuer Common Stock representing approximately 2.09% of the outstanding shares. As members of a group, Big Star, Thomas Wheeler, Big Beaver, Westar Associates and Westar II may be deemed to be the beneficial

owners of Mr. Argyros' shares. Big Star, Mr. Wheeler, Big Beaver, Westar Associates and Westar II disclaim beneficial ownership of such shares. In addition, John Clark owns 2,500 shares of Issuer Common Stock and has the right to acquire pursuant to currently exercisable options 11,000 shares of Issuer Common Stock representing less than 1% of the outstanding shares (after giving effect to the exercise of such option). Neither Paul Oster nor Oscar B. Marx, III beneficially own any shares of Issuer Common Stock. (c) Neither the Reporting Persons nor, to the knowledge of the Reporting Persons, any person named in Item 2 pursuant to Instruction C of Schedule 13D, has effected any transaction in the Issuer Common Stock during the past 60 days. (d) None. (e) Not applicable. ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER. Other than the Credit Agreement, Bridge Loan Warrant, Contingent Warrants, Shareholders' Agreement (as described in the First Amendment), Amended Rights Agreement, to the knowledge of the Reporting Persons, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the persons named in Item 2 and between such persons and any person with respect to any securities of the Issuer, including but not limited to transfer or voting of any of the securities, finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.

In addition, the Company acknowledges that neither the Lender nor either of its investors have been granted the requisite internal approvals which are a condition to the making of Additional Loans and such approvals may not be forthcoming and would only be obtained in the sole discretion of the Lender and its investors. Nothing in this Agreement or any other Loan Document shall constitute a commitment or other undertaking by the Lender or any of its investors or affiliates to make Additional Loans. SECTION 2.02 BORROWING PROCEDURE. Each Loan shall be made upon written notice from the Company to the Lender, which notice shall be received by the Lender not later than 10:00 A.M. (California time) at least three (3) Business Days prior to the proposed borrowing date. Each such notice of borrowing shall be irrevocable and binding on the Company and shall specify the proposed date of the borrowing (which shall be a Business Day), the amount of the borrowing (which shall be at least $200,000 or a greater amount which is an integral multiple of $50,000), and payment instructions with respect to the funds to be made available to the Company. Upon fulfillment of the applicable conditions set forth in Article III hereof, the Lender shall make the Loan available to the Company in same day funds, or such other funds as shall separately be agreed upon by the Company and the Lender, in accordance with the payment instructions provided to the Lender as set forth in the borrowing request delivered pursuant hereto. SECTION 2.03 EVIDENCE OF INDEBTEDNESS.

SECTION 2.04 INTEREST. The Company hereby promises to pay interest on the unpaid principal amount of each Loan from the date of such Loan until the maturity thereof, at a rate equal to 10% per annum, on the date of any prepayment of any such Loan and at maturity. Any principal payments on the Loans not paid when due and, to the extent permitted by applicable law, any interest payments on the Loans not paid when due, in each case whether at stated maturity, by notice of prepayment, by acceleration or otherwise, shall thereafter bear interest (including post-petition interest in any proceeding under applicable bankruptcy laws)

payable on demand at a rate which is 2% per annum in excess of the interest rate otherwise payable under this Agreement for Loans. Payment or acceptance of the increased rates of interest provided for in this paragraph is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies of Lender. SECTION 2.05 COMPUTATIONS. All computations of fees and interest hereunder shall be made on the basis of a year of 360 days for the actual number of days occurring in the period for which any such interest or fee is payable. SECTION 2.06 HIGHEST LAWFUL RATE. Anything herein to the contrary notwithstanding, if during any period for which interest is computed hereunder, the applicable interest rate, together with all fees, charges and other payments which are treated as interest under applicable law, as provided for herein or in any other Loan Document, would exceed the maximum rate of interest which may be charged, contracted for, reserved, received or collected by the Lender in connection with this Agreement under applicable law (the "Maximum Rate"), the Company shall not be obligated to pay, and the Lender shall not be entitled to charge, collect, receive, reserve or take, interest in excess of the Maximum Rate, and during any such period the interest payable hereunder shall be limited to the Maximum Rate. SECTION 2.07 TERMINATION OF THE COMMITMENT. Upon the earlier to occur of (i) August 31, 2000, (ii) the occurrence of a Trigger Event, or (iii) the Lender's declaration of an Event of Default, any unused portion of the Term Commitment shall terminate.

The Company hereby promises to pay to the Lender the principal amount of the Term Loans and any accrued interest thereon in full on the Final Maturity Date. SECTION 2.09 PREPAYMENTS OF THE LOANS. (a) OPTIONAL PREPAYMENTS. The Company may, upon prior notice to the Lender, prepay the outstanding amount of the Loans in whole or in part, without premium or penalty. (b) NOTICE; APPLICATION. The notice given of any prepayment shall specify the date and amount of the prepayment. If the notice of prepayment is given, the Company shall make such prepayment and the prepayment amount specified in such notice shall be due and payable on the date specified therein, with accrued interest to such date on the amount prepaid. SECTION 2.10 PAYMENTS. (a) PAYMENTS. The Company shall make each payment under the Loan Documents, unconditionally in full without deduction, set-off, counterclaim or, to the extent permitted by applicable law, other defense, and free and clear of, and without reduction for or on account of, any present and future taxes or withholdings (other than a tax on the overall net income of the Lender), and all liabilities with respect thereto. Each payment shall be made not later

than 11:00 A.M. (California time) on the day when due to the Lender in U.S. dollars and in immediately available funds, or such other funds as shall be separately agreed upon by the Company and the Lender, in accordance with the Lender's payment instructions. (b) EXTENSION. Whenever any payment hereunder shall be stated to be due, or whenever any interest payment date or any other date specified hereunder would otherwise occur, on a day other than a Business Day, then, except as otherwise provided herein, such payment shall be made, and such interest payment date or other date shall occur, on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest. (c) APPLICATION. Each payment by or on behalf of the Company hereunder shall, unless a specific determination is made by the Lender with respect thereto, be applied (i) first, to accrued and unpaid interest due the Lender; and (ii) second, to principal due the Lender. SECTION 2.11 CONVERSION OF LOANS INTO CLASS A COMMON STOCK. The Lender shall have conversion rights as follows (the "Conversion Rights"): (a) CONVERSION RIGHTS. The Lender may elect in its sole discretion to convert the principal of or interest accrued under all or a portion of any Loan into Class A Common Stock of the Company at a conversion price equal to the Market Price of the Class A Common Stock as of the date that such Loan was made to the Company; provided that in the event the Company issues in excess of $5 million of equity securities in an offering at an issuance price that is less than the Market Price with respect to a particular Loan, the conversion price relating to such Loan shall be reduced to such issuance price (the "Conversion Price"). The Conversion Price for the Note shall be subject to adjustment as set forth in subsection 2.11(c). (b) MECHANICS OF CONVERSION. Before the Lender shall be entitled to convert the Note into shares of Class A Common Stock, the Lender shall, in the case of a partial conversion of the Note, indicate on the face of the Note the amount so converted and provide a copy of the Note to the Company or, in the case of the conversion of all of the remaining outstanding principal and interest due under the Note, surrender the Note, duly endorsed, at the office of the Company and shall give written notice to the Company at its principal corporate office, of the election to convert the same or a portion thereof and shall state therein the name or names in which the certificate or certificates for shares of Class A Common Stock are to be issued. The Company shall, as soon as practicable thereafter, issue and deliver at such office to Lender, or to the nominee or nominees of Lender, a certificate or certificates for the number of shares of Class A Common Stock to which such persons shall be entitled as aforesaid. Such conversion shall be deemed to have been made immediately prior to the close of business on the date of such surrender of the Note and the person or persons entitled to receive the shares of Class A Common Stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such shares of Class A Common Stock 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 Lender, 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 A Common Stock upon conversion of the Note shall not be deemed to have converted such Note until immediately prior to the closing of such sale of securities. (c) CONVERSION PRICE ADJUSTMENTS OF NOTE FOR CERTAIN DILUTIVE ISSUANCES, SPLITS AND COMBINATIONS. The Conversion Price of the Note 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 Closing Date fix a record date for the effectuation of a split or subdivision of the outstanding shares of Class A Common Stock or the determination of holders of Class A Common Stock entitled to receive a dividend or other distribution payable in additional shares of Class A Common Stock without payment of any consideration by such holder for the additional shares of Class A Common Stock, then, as of such record date (or the date of such dividend distribution, split or subdivision if no record date is fixed), the Conversion Price of the Note shall be appropriately decreased so that the number of shares of Class A Common Stock issuable on conversion of the Note shall be increased in proportion to such increase of the aggregate of shares of Class A Common Stock outstanding. In the event the Company shall declare or pay, without consideration, any dividend on the Class A Common Stock payable in any right to acquire Class A Common Stock for no consideration, then the Company shall be deemed to have made a dividend payable in Class A Common Stock in an amount of shares equal to the maximum number of shares issuable upon exercise of such rights to acquire Class A Common Stock. (ii) If the number of shares of Class A Common Stock outstanding at any time after the Closing Date is decreased by a combination of the outstanding shares of common stock, then, following the record date of such combination, the Conversion Price for the Note shall be appropriately increased so that the number of shares of Class A Common Stock issuable on conversion of the Note or a portion thereof shall be decreased in proportion to such decrease in outstanding shares. (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 2.11(c)(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. (d) RECAPITALIZATIONS AND REORGANIZATIONS. If the Class A Common Stock issuable upon conversion of the Note shall be changed into or exchanged for a different class or classes of capital stock, 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 2.11) provision shall be made so that the Lender shall thereafter be entitled to receive upon conversion of the Note the number of shares of stock or other securities or property, to which a holder of Class A Common Stock 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 2.11 with respect to the rights of the Lender after the recapitalization or reorganization to the end that the provisions of this Section 2.11 (including adjustment of the Conversion Price then in effect and the number of shares purchasable upon conversion of the Note) shall be applicable after the event as nearly equivalent as may be practicable. (e) NO IMPAIRMENT. The Company will not, by amendment of its Articles of Incorporation 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 performances 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 all of the provisions of this Section 2.11 and in the taking of all such action as may be necessary or appropriate in order to protect the Conversion Rights of the Lender against impairment. (f) NO FRACTIONAL SHARES AND CERTIFICATE AS TO ADJUSTMENTS. (i) No fractional shares shall be issued upon the conversion of the Note and the number of shares of Class A Common Stock to be issued shall be rounded to the nearest whole share. Whether or not fractional shares are issuable upon such conversion shall be determined on the basis of the amount of Note the Lender is at the time converting into Class A Common Stock and the number of shares of Class A Common Stock issuable upon such aggregate conversion. (ii) Upon the occurrence of each adjustment or readjustment of the Conversion Price of the Note pursuant to this Section 2.11, the Company, at its expense, shall promptly compute such adjustment or readjustment in accordance with the terms hereof and prepare and furnish to the Lender 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 the Lender, furnish or cause to be furnished to the Lender a like certificate setting forth (A) such adjustment and readjustment, (B) the Conversion Price for the Note at the time in effect , and (C) the number of shares of Class A Common Stock and the amount, if any, of other property which at the time would be received upon the conversion of the Note. (g) NOTICES OF RECORD DATE. In the event of any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend (other than a cash dividend) or other distribution ,any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities or property, or to receive any other right (except the right to vote), the Company shall mail to the Lender at least 20 days prior to the date specified therein, a notice specifying the date on which any such record is to be taken for the purpose of such dividend, distribution or right, and the amount and character of such dividend, distribution or right.

(h) RESERVATION OF STOCK ISSUABLE UPON CONVERSION. The Company shall at all times reserve and keep available out of its authorized but unissued shares of Class A Common Stock, solely for the purpose of effecting conversion of the Note, such number of its shares of Class A Common Stock as shall from time to time be sufficient to effect the conversion of the Note; and it at any time the number of authorized but unissued shares of Class A Common Stock shall not be sufficient to effect the conversion of the Note, in addition to such other remedies as shall be available to the Lender, the Company will take such corporate action as may, in the option of its counsel, be necessary to increase its authorized but unissued shares of Class A Common Stock to such number of shares as shall be sufficient for such purposes, including, without limitation, engaging in best efforts to obtain the requisite shareholder approval of any necessary amendment to its articles of incorporation. (i) NO STOCKHOLDER RIGHTS. Nothing contained in this Agreement shall be construed as conferring upon the Lender or any other person the right to vote or to consent to receive notice as a stockholder in respect of meeting of stockholders for the election of directors of the Company or any or any other matters or any other rights whatsoever as a stockholder of the Company; and no dividends or interest shall be payable or accrued in respect of the Note or the Class A Common Stock obtainable under this Section 2.11 until, and only to the extent that, this Note shall have been converted. (j) Any Loans that are converted into Class A Common Stock as provided herein will be deemed to be paid in full for all purposes of this Agreement and the other Loan Documents. SECTION 2.12 WARRANTS.

(c) The Exercise Price of any Warrants shall be equal to the Conversion Price calculated as of the date of the particular Loan as further provided in the Bridge Loan Warrants. SECTION 2.13 LIMITATION ON CONVERSION RIGHTS AND EXERCISE OF WARRANTS. In no event shall the Lender be entitled to convert the Note or exercise the Warrants to the extent that, after giving effect to such conversion or exercise, the Lender shall have acquired pursuant to such conversion and exercise more than 19.99% of the outstanding

Class A Common Stock of the Company such that a shareholder vote would have been required in connection with the issuance of the Note and the Bridge Loan Warrants under applicable NASDAQ rules or to the extent that the Class A Common Stock issued pursuant to the conversion or exercise of the Note and the Bridge Loan Warrants exceeds the amount approved by the California Department of Corporations. In the event Lender anticipates that the Class A Common Stock issued pursuant to the conversion or exercise of the Note and the Bridge Loan Warrants may exceed the amount approved by the California Department of Corporations, then at the Lender's request the Company shall apply for an additional permit from the California Department of Corporations covering any additional shares of Class A Common Stock requested by Lender and use its best efforts to have such application approved.

SECTION 7.06 BENEFITS OF AGREEMENT.

SECTION 7.11 SEVERABILITY. Whenever possible, each provision of the Loan Documents shall be interpreted in such manner as to be effective and valid under all applicable laws and regulations. If, however, any provision of any of the Loan Documents shall be prohibited by or invalid under any such law or regulation in any jurisdiction, it shall, as to such jurisdiction, be deemed modified to conform to the minimum requirements of such law or regulation, or, if for any reason it is not deemed so modified, it shall be ineffective and invalid only to the extent of such prohibition or invalidity without affecting the remaining provisions of such Loan Document, or the validity or effectiveness of such provision in any other jurisdiction.

AMERIGON INCORPORATED WARRANT TO PURCHASE COMMON STOCK This Warrant (the "Warrant") represents and certifies that, for value received, Big Star Investments LLC, a Delaware limited liability company (the "Holder") is entitled to subscribe for and purchase shares (subject to adjustment from time to time pursuant to the provisions of Section 5 hereof) of fully paid and nonassessable Class A Common Stock of Amerigon Incorporated, a California corporation (the "Company"), of an amount up to 10% of the principal amount of the Loans (as defined below) divided by the relevant Exercise Price (as defined below) at the relevant Exercise Price specified in Section 2 hereof, as such price may be adjusted from time to time pursuant to Section 5 hereof, subject to the provisions and upon the terms and conditions hereinafter set forth. As used herein, the term "Loans" shall mean the $1.5 million bridge facility (the "Initial Loans") to be advanced to Company by Holder pursuant to the Credit Agreement, dated as of March 16, 2000, between the Company and the Holder (as amended or modified from time to time, the "Credit Agreement") and, in the event the Holder makes or commits to make in its sole discretion additional advances thereunder of up to an aggregate of $2.5 million in principal amount of additional loans under the Credit Agreement (the "Additional Loans"), shall also mean such principal amount of Additional Loans. The date (if any) on which the Holder makes any Initial Loan or any Additional Loan is referred to herein as a "Loan Date." As used herein, the term "Class A Common Stock" shall mean the Company's presently authorized Class A Common Stock, no par value, and any stock into or for which such Common Stock may hereafter be converted or exchanged.

As used herein, the term "Exercise Price" shall mean, with respect to the portion of this Warrant that is allocable to any Loan, the Market Price of the Class A Common Stock as of the Loan Date of such Loan, provided that the Exercise Price shall be subject to adjustment as provided in Section 5 hereof. As used herein, the term "Market Price of the Class A Common Stock" shall have the meaning set forth in Section 3(b) hereof. 1. TERM OF WARRANT. a. TERM. The purchase right represented by this Warrant is exercisable, in whole or in part, at any time during a period beginning on the date hereof and ending five years after such date, but shall not be exercisable as to the portion of this Warrant allowable to any Loans unless the Loan Date with respect thereto has occurred. 2. EXERCISE PRICE. The Exercise Price shall be as provided in the definition of Exercise Price, subject to adjustment from time to time pursuant to the provisions of Section 5 hereof. 3. METHOD OF EXERCISE OR CONVERSION; PAYMENT; ISSUANCE OF NEW WARRANT. a. EXERCISE. Subject to Section 1 hereof, the purchase right represented by this Warrant may be exercised by the Holder, in whole or in part, by the surrender of this Warrant (with the notice of exercise form attached hereto as EXHIBIT 1 duly executed) at the principal office of the Company and by the payment to the Company, by cashier's check or wire transfer, of an amount equal to the then applicable Exercise Price per share multiplied by the number of shares then being purchased. The Company agrees that the shares so purchased shall be deemed to be issued to the Holder as the record owner of such shares as of the close of business on the date on which this Warrant shall have been surrendered and payment made for such shares as aforesaid. In the event of any exercise of this Warrant, certificates for the shares of stock so purchased shall be delivered to the Holder within 15 business days thereafter and, unless this Warrant has been fully exercised or expired, a new Warrant representing the portion of the shares, if any, with respect to which this Warrant shall not then have been exercised, shall also be issued to the Holder within such 15 business day period. b. CONVERSION. Subject to Section 1 hereof, the Holder may convert this Warrant (the "Conversion Right"), in whole or in part, into the number of shares (less the number of shares which have been previously exercised or as to which the Conversion Right has been previously exercised) calculated pursuant to the following formula by surrendering this Warrant (with the notice of exercise form attached hereto as EXHIBIT 1 duly executed) at the principal office of the Company specifying the number of shares the rights to purchase which the Holder desires to convert:

X = Y ------- B where: X = the number of shares of Class A Common Stock to be issued to the Holder; Y = 10% of the Principal Amount of the Loans; and B = the Exercise Price, as such price may be adjusted from time to time pursuant to Section 5 hereof For purposes hereof, the "Market Price of the Class A Common Stock," with respect to the portion of this Warrant allocable to a particular Loan, shall be (i) the average closing bid price of the Class A Common Stock, for ten (10) consecutive business days ending on the Loan Date of such Loan, as reported by Nasdaq, if the Class A Common Stock is traded on the Nasdaq SmallCap Market, or (ii) the average last reported sale price of the Class A Common Stock, for ten (10) consecutive business days ending on such applicable Loan Date, as reported by the primary exchange on which the Class A Common Stock is traded, if the Class A Common Stock is traded on a national securities exchange, or by Nasdaq, if the Class A Common Stock is traded on the Nasdaq National Market. The Company agrees that the shares so converted shall be deemed issued to the Holder as the record owner of such shares as of the close of business on the date on which this Warrant shall have been surrendered as aforesaid. In the event of any conversion of this Warrant, certificates for the shares of stock so converted shall be delivered to the holder hereof within 15 business days thereafter and, unless this Warrant has been fully converted or expired, a new Warrant representing the portion of the shares, if any, with respect to which this Warrant shall not then have been converted, shall also be issued to the holder hereof within such 15-day period. 4. STOCK FULLY PAID; RESERVATION OF SHARES. All Class A Common Stock which may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be fully paid and nonassessable, and free from all United States taxes, liens and charges with respect to the issue thereof. During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of the issuance upon exercise of the purchase rights evidenced by this Warrant, a sufficient number of shares of its Class A Common Stock to provide for the exercise of the rights represented by this Warrant. 5. ADJUSTMENT OF PURCHASE PRICE AND NUMBER OF SHARES. a. ADDITIONAL SHARES. In the event that the Company shall issue additional shares of Class A Common Stock, or other securities exchangeable for, exercisable

for, or convertible into additional shares of Class A Common Stock, in each case in an equity offering in excess of $5 million, for consideration per share less than the Exercise Price relating to a portion of this Warrant allocable to a particular Loan on the date of and immediately prior to any such issue, then and in such event, the per share Exercise Price relating to the portion of this Warrant allocable to such Loan shall be reduced concurrently with such issuance or sale, to a price equal to the consideration per share of such issuance; provided that such Exercise Price shall not be so reduced at such time if the amount of such reduction would be an amount less than $0.01, but any such amount shall be carried forward and reduction with respect thereto made at the time of and together with any subsequent reduction which, together with such amount and any other amount or amounts so carried forward, shall aggregate $0.01 or more. No adjustment in the Exercise Price shall be made on account of (i) the grant of options exercisable for, or sales of, Class A Common Stock pursuant to employee benefit plans previously approved by the Company's shareholders, (ii) the issuance of stock, warrants or other securities or rights to persons or entities with which the Company has business relationships provided such issuances are for other than primarily equity financing purposes and provided that (x) any such issuance does not exceed 2% of the then outstanding Class A Common Stock of the Company (assuming full conversion and exercise of all convertible and exercisable securities) and (y) the aggregate of all such issuances since the date of this Warrant do not exceed 5% of the then outstanding Class A Common Stock of the Company (assuming full conversion and exercise of all convertible and exercisable securities). b. STOCK SPLITS AND COMBINATIONS. If the Company at any time or from time to time after the date this Warrant is issued effects a subdivision of the outstanding Class A Common Stock pursuant to a stock split or similar event, the Exercise Price shall be proportionately decreased, and conversely, if the Company at any time or from time to time after the date this Warrant is issued combines the outstanding shares of Class A Common Stock into a smaller number of shares in a reverse stock split or similar event, the Exercise Price shall be proportionately increased. Upon the adjustment of the Exercise Price pursuant to the foregoing provisions, the number of shares of Class A Common Stock subject to the exercise of the Warrant shall be adjusted to the nearest full share by multiplying the shares subject to the Warrant by a fraction, the numerator of which is the Exercise Price immediately prior to such adjustment and the denominator of which is the Exercise Price immediately after such adjustment. Any adjustment under this subsection (b) shall be effective at the close of business on the date the subdivision or combination becomes effective. c. CERTAIN DIVIDENDS AND DISTRIBUTIONS. If the Company at any time or from time to time after the date this Warrant is issued makes, or fixes a record date for the determination of holders of Class A Common Stock entitled to receive a dividend or other distribution payable in additional shares of Class A Common Stock, then and in each such event the number of shares of Class A Common Stock subject to the Warrant shall be increased and the Exercise Price then in effect shall be decreased as of the date of such issuance or, in the event such record date is fixed, as of the close of business on such record date, by:

(i) multiplying the Exercise Price then in effect by a fraction (1) the numerator of which is the total number of shares of Class A Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date, and (2) the denominator of which shall be the total number of shares of Class A Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of shares of Class A Common Stock issuable in payment of such dividend or distribution; and (ii) multiplying the number of shares of Class A Common Stock subject to the Warrant by a fraction (1) the numerator of which is the total number of shares of Class A Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of shares of Class A Common Stock issuable in payment of such dividend or distribution, and (2) the denominator of which shall be the total number of shares of Class A Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date. If, however, such record date is fixed and such dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, the number of shares of Class A Common Stock subject to the Warrant and the Exercise Price thereof shall be recomputed accordingly as of the close of business on such record date and thereafter shall be adjusted pursuant to this subsection(c) as of the time of actual payment of such dividends or distributions. d. OTHER ADJUSTMENTS. In the event the Company at any time or from time to time after the date this Warrant is issued: (i) makes a dividend or other distribution payable in securities of the Company other than shares of Class A Common Stock, or (ii) changes any Class A Common Stock into the same or a different number of shares of any class or classes of stock, whether by recapitalization, reclassification or otherwise (other than a subdivision or combination of shares or stock dividend or a reorganization, merger, consolidation or sale of assets provided for elsewhere in this Section 5), or (iii)effects a capital reorganization of the Class A Common Stock (other than a recapitalization, subdivision, combination, reclassification or exchange of shares provided for elsewhere in this Section 5) or merger or consolidation of the Company with or into another corporation, or the sale of all or substantially all of the Company's properties and assets to any other person, then, in each such event, any and all new, substituted or additional securities to which Holder is or would be entitled by reason of its ownership of the shares underlying this Warrant shall be immediately subject to the Warrant and be included in the shares underlying this Warrant for all purposes hereunder. After each such event, the Exercise Price per share shall be proportionately adjusted so that the aggregate Exercise Price upon exercise of the Warrant shall remain the same as before such event.

6. NOTICE OF ADJUSTMENTS. Whenever any Exercise Price shall be adjusted pursuant to Section 5 hereof, the Company shall prepare a certificate signed by its chief financial officer setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, the Exercise Price after giving effect to such adjustment and the number of shares then purchasable upon exercise of this Warrant, and shall cause copies of such certificate to be mailed (by first class mail, postage prepaid)to the Holder of this Warrant at the address specified in Section 9(c) hereof, or at such other address as may be provided to the Company in writing by the Holder of this Warrant. 7. FRACTIONAL SHARES. No fractional shares of Class A Common Stock will be issued in conjunction with any exercise hereunder, but in lieu of such fractional shares the Company shall make a cash payment therefore on the basis of the Exercise Price then in effect. 8. COMPLIANCE WITH SECURITIES ACT. The Holder of this Warrant, by acceptance hereof, agrees that this Warrant and the shares of Class A Common Stock to be issued on exercise hereof are being acquired for investment and that it will not offer, sell or otherwise dispose of this Warrant or any shares of Class A Common Stock to be issued upon exercise hereof except under circumstances which will not result in a violation of the Securities Act of 1933, as amended (the "Act"). This Warrant and all shares of Class A Common Stock issued upon exercise of this Warrant (unless registered under the Act) shall be stamped and imprinted with a legend substantially in the following form: "THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR APPLICABLE STATE SECURITIES LAWS AND MAY NOT BE TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS IT HAS BEEN REGISTERED UNDER THE ACT AND SUCH LAWS OR (1) REGISTRATION UNDER SUCH LAWS IS NOT REQUIRED AND (2) AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY IS FURNISHED TO THE COMPANY TO THE EFFECT THAT REGISTRATION UNDER THE ACT AND THE APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED." 9. MISCELLANEOUS. a. NO RIGHTS AS SHAREHOLDER. The Holder of this Warrant shall not be entitled to vote or receive dividends or be deemed the Holder of Class A Common Stock or any other securities of the Company that may at any time be issuable on the exercise hereof for any purpose, nor shall anything contained herein be construed to confer upon the Holder of this Warrant, as such, any of the rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, change of par value or change of stock to no par value, consolidation, merger, conveyance or otherwise) or to receive notice of

meetings, or to receive dividends or subscription rights or otherwise until the Warrant shall have been exercised and the shares purchasable upon the exercise hereof shall have become deliverable, as provided herein. b. REPLACEMENT.
