SECURITIES AND EXCHANGE COMMISSION Washington, D.C. 20549 ___________________ FORM 8-K CURRENT REPORT PURSUANT TO SECTION 13 OR 15(d) OF THE SECURITIES EXCHANGE ACT OF 1934 Date of Report (Date of earliest event reported): September 20, 2001 ___________________ AMERIGON INCORPORATED (Exact name of registrant as specified in its charter) ___________________ California 0-21810 95-4318554 (State or other jurisdiction of (Commission (I.R.S. Employer incorporation or organization) File Number) Identification No.) 5462 Irwindale Avenue Irwindale, California 91706 (626) 815-7400 (Address, including zip code, and telephone number, including area code, of registrant's principal executive offices) ___________________ Item 5. Other Events. On September 20, 2001, the Company obtained a loan from Big Beaver Investments LLC ("Big Beaver"), one of the Company's principal shareholders, for an initial advance of $500,000 and, at the Company's request and subject to certain conditions precedent, additional advances of up to an additional $1.0 million. The bridge loan is secured by substantially all personal property of the Company. The bridge loan is necessary to allow the Company to continue operations pending the raising of additional financing. The amount of the bridge loan may not be adequate to permit the Company to continue operations beyond December 1, 2001 even if fully drawn. The advances accrue interest at 10% per annum, which is payable at maturity or on the date of any prepayment. The principal and accrued interest of the initial loan are convertible at any time into Common Stock at a conversion price equal to the average closing bid price of the Common Stock during the ten days preceding the date of the bridge loan (the "Market Price"). In the event the Company issues in excess of $1.5 million of equity securities in an offering at an issuance price that is less than the Market Price with respect to the bridge loan, the conversion price will be adjusted to the issuance price of the equity securities. Additional advances will also be convertible based on the average price of the Company's Common Stock during the ten days preceding such additional advances. The loans mature and all outstanding principal and accrued interest become due and payable on the earlier of December 1, 2001, or when the Company (or its Board of Directors) shall have authorized, recommended, proposed or publicly announced its intention to enter into (or has failed to recommend rejection of) any tender or exchange offer,

merger, consolidation, liquidation,dissolution, business combination, recapitalization, acquisition, or disposition of a material amount of the assets or securities or any comparable transaction which has not been consented to in writing by Big Beaver. In connection with the bridge loan, the Company issued to Big Beaver a warrant for the right to purchase _______ shares of the Company's Common Stock (equal to 18% of the principal amount of $1.5 million divided by the conversion price). The exercise price of the warrant is adjustable in the same manner as the conversion price of the loan. The proceeds of the bridge loan were allocated among the bridge loan and the warrant based upon their relative fair values. If, after giving effect to Big Beaver's conversion rights under the bridge loan and exercise rights under the warrant, Big Beaver will have the right to acquire more than 20% of the outstanding common stock of the Company such that a shareholder vote would be required under applicable Nasdaq rules, then Big Beaver's rights will be limited to only 19.99% of the outstanding common stock until the Company complies with such Nasdaq rules. The Company has agreed to use its best efforts to comply with the Nasdaq rules, including the obtaining of any shareholder approvals, to permit Big Beaver to exercise its rights in full.

Any principal payments on the Loan not paid when due and, to the extent permitted by applicable law, any interest payments on the Loan 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 five percent (5%) per annum in excess of the interest rate otherwise payable under this Agreement for the Loan.

SECTION 2.07 [INTENTIONALLY OMITTED] SECTION 2.08 REPAYMENT OF THE LOAN. The Company hereby promises to pay to the Lender the outstanding principal amount of the Loan 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 Loan 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. Each prepayment 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 2.10 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 or 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 in writing by the Company and the Lender, in accordance with the Lender's payment instructions.

(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 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 and/or interest accrued under all or a portion of the Note into Common Stock at a conversion price equal to the Market Price of the Common Stock; provided, however, that if the 7

Company, while any of the Obligations shall remain unpaid or the Lender shall have any Commitment, issues equity securities in excess of One Million Five Hundred Thousand Dollars ($1,500,000) in an offering at an issuance price that is less than the Market Price, the conversion price shall be reduced to such issuance price (the "Conversion Price"). The Conversion Price shall be subject to adjustment as set forth in Section 2.11(c). (b) MECHANICS OF CONVERSION. Before the Lender shall be entitled to convert the Note into shares of 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 Common Stock are to be issued. The Company shall, as soon as practicable thereafter, issue and deliver at such office to the Lender, or to the nominee or nominees of the Lender, a certificate or certificates for the number of shares of 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 (or a copy thereof as provided herein) and the person or persons entitled to receive the shares of Common Stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such shares of 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, as amended (the "Securities Act"), the conversion may, at the option of the Lender, be conditioned upon the closing with the underwriters of the sale of securities pursuant to such offering, in which event the person or persons entitled to receive the 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 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 Common Stock or the determination of holders of Common Stock entitled to receive a dividend or other distribution payable in additional shares of Common Stock without payment of any consideration by such holder for the additional shares of 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 Common Stock issuable on conversion of the Note shall be increased in proportion to such increase of the aggregate of shares of Common Stock outstanding. In the event the Company shall declare or pay, without consideration, any dividend on the Common Stock payable in any right to acquire Common Stock for no consideration, then the Company shall be deemed to have made a dividend payable in Common Stock in an amount of shares equal to the maximum number of shares issuable upon exercise of such rights to acquire Common Stock. 8

(ii) If the number of shares of 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 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 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 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 any of its Charter Documents 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 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 the Note the Lender is at the time converting into Common Stock and the number of shares of 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, 9

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 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 twenty (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 Common Stock, solely for the purpose of effecting conversion of the Note, such number of its shares of Common Stock as shall from time to time be sufficient to effect the conversion of the Note; and if at any time the number of authorized but unissued shares of 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 opinion of its counsel, be necessary to increase its authorized but unissued shares of 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 Charter Documents. (i) NO SHAREHOLDER 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 shareholder in respect of meeting of shareholders for the election of directors of the Company or any or any other matters or any other rights whatsoever as a shareholder of the Company and no dividends or interest shall be payable or accrued in respect of the Note or the Common Stock obtainable under this Section 2.11 until, and only to the extent that, the Note shall have been converted. (j) SATISFACTION OF THE LOAN UPON CONVERSION. If the Note is converted in full into Common Stock as provided herein, it will be deemed to be payment in full for all purposes of this Agreement and the other Loan Documents (except the Bridge Loan Warrant), or if the Note is converted in part into Common Stock as provided herein, it will be deemed to be payment under this Agreement and the other Loan Documents (except the Bridge Loan Warrant) up to the amount of the Note so converted. 10

SECTION 2.12 WARRANT.

Any such amendment, waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. SECTION 7.02 NOTICES. All notices and other communications provided for hereunder and under the other Loan Documents shall, unless otherwise stated herein, be in 23

writing (including by facsimile transmission) and mailed, sent or delivered to the respective parties hereto at or to their respective addresses or facsimile numbers set forth below their names on the signature pages hereof, or at or to such other address or facsimile number as shall be designated by any party in a written notice to the other party hereto. All such notices and communications shall be effective: (i) if delivered by hand, when delivered; (ii) if sent by mail, upon the earlier of the date of receipt or five (5) Business Days after deposit in the mail, first class, postage prepaid; or (iii) if sent by facsimile transmission, when sent; provided, however, that notices and communications to the Lender pursuant to Article II shall not be effective until received.

The rights and remedies under the Loan Documents are cumulative and not exclusive of any rights, remedies, powers and privileges that may otherwise be available to the Lender. SECTION 7.04 COSTS AND EXPENSES; INDEMNITY. (a) COSTS AND EXPENSES. The Company agrees to pay on demand: (i) the reasonable out-of-pocket costs and expenses of the Lender and any of its Affiliates, and the reasonable fees and disbursements of counsel to the Lender and its Affiliates, in connection with the Loan, including the negotiation, preparation, execution, delivery and administration of the Loan Documents and any amendments, modifications or waivers of the terms thereof, and (ii) all reasonable costs and expenses of the Lender and its Affiliates, and fees and disbursements of counsel, in connection with (A) any Default, (B) the enforcement or attempted enforcement of, and preservation of any rights or interests under, the Loan Documents, (C) any out-of-court workout or other refinancing or restructuring or any bankruptcy or insolvency case or proceeding, and (D) the preservation of and realization upon any of the Collateral. Without limiting the foregoing, the costs and reasonable fees of counsel to the Lender and its Affiliates incurred or reasonably expected to be incurred in connection with the Loan will be automatically deducted from the disbursement of the Second Loan Advance and, accordingly, the amount of the Second Loan Advance actually disbursed to the Company will be less of such fees and costs. (b) INDEMNIFICATION. Whether or not the transactions contemplated hereby shall be consummated, the Company hereby agrees to indemnify the Lender, any Affiliate thereof and their respective directors, officers, employees, agents, counsel and other advisors (each an "Indemnified Person") against, and hold each of them harmless from, any and all liabilities, obligations, losses, claims, damages, demands, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever, including the reasonable fees and disbursements of counsel to an Indemnified Person, which may be imposed on, incurred by, or asserted against any Indemnified Person, (i) in any way relating to or arising out of any of the Loan Documents, the use or intended use of the proceeds of the Loan or the transactions contemplated hereby or thereby, (ii) with respect to any investigation, litigation or other proceeding relating to any of the foregoing, irrespective of whether the Indemnified Person shall be designated a party thereto, and/or (iii) in any way relating to or arising out of the use, 24

generation, manufacture, installation, treatment, storage or presence, or the spillage, leakage, leaching, migration, dumping, deposit, discharge, disposal or release, at any time, of any Hazardous Substances on, under, at or from any properties of the Company, including any personal injury or property damage suffered by any Person, and any investigation, site assessment, environmental audit, feasibility study, monitoring, clean-up, removal, containment, restoration, remedial response or remedial work undertaken by or on behalf of any Indemnified Person at any time, voluntarily or involuntarily, with respect to the Premises (the "Indemnified Liabilities"); provided that the Company shall not be liable to any Indemnified Person for any portion of such Indemnified Liabilities to the extent they are found by a final decision of a court of competent jurisdiction to have resulted from such Indemnified Person's gross negligence or willful misconduct. If and to the extent that the foregoing indemnification is for any reason held unenforceable, the Company agrees to make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law. SECTION 7.05 SURVIVAL. All covenants, agreements, representations and warranties made in any Loan Document shall, except to the extent otherwise provided therein, survive the execution and delivery of this Agreement, the making of the Loan, the making of all Loan Advances, and the execution and delivery of the Note, and shall continue in full force and effect so long as the Lender has any Commitment, the Loan remains outstanding or any other Obligations remain unpaid or any obligation to perform any other act hereunder or under any other Loan Document remains unsatisfied. Without limiting the generality of the foregoing, the obligations of the Company under Section 7.04, and all similar obligations under the other Loan Documents (including all obligations to pay costs and expenses and all indemnity obligations), shall survive the repayment of the Loans and the termination of the Commitment. SECTION 7.06 BENEFITS OF AGREEMENT. The Loan Documents are entered into for the sole protection and benefit of the parties hereto and their permitted successors and permitted assigns, and no other Person shall be a direct or indirect beneficiary of, or shall have any direct or indirect cause of action or claim in connection with, any Loan Document. SECTION 7.07 BINDING EFFECT; ASSIGNMENT. This Agreement shall become effective when it shall have been executed by the Company and the Lender and thereafter shall be binding upon, inure to the benefit of and be enforceable by the Company, the Lender and their respective permitted successors and permitted assigns. The Company shall not have the right to assign its rights or Obligations or any interest herein or therein without the prior written consent of the Lender. The Lender reserves the right freely to sell, assign, transfer or grant participations in all or any portion of the Lender's rights and obligations hereunder and under the other Loan Documents (i) to one or more Affiliates of the Lender and/or (ii) with the prior consent of the Company (which consent shall not be unreasonably withheld) to any other Person. In the event of any such assignment, the assignee shall be deemed a "Lender" for all purposes of the Loan Documents with respect to the rights and obligations assigned to it, and the obligations of the Lender so assigned shall thereupon terminate. The Company shall, from time to time upon request of the Lender, enter into such amendments to the Loan Documents and execute and deliver such other documents as shall be necessary to effect any such grant or assignment. The Company agrees that in connection with any such grant or assignment, the Lender may deliver to the prospective participant or assignee financial statements and other 25

relevant information relating to the Company (subject to such Person entering into a confidentiality agreement with the Company on terms reasonably satisfactory to the Company). SECTION 7.08 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF CALIFORNIA. SECTION 7.09 WAIVER OF JURY TRIAL. THE COMPANY AND THE LENDER EACH WAIVE THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF OR RELATED TO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS, OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, IN ANY ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY OF THE PARTIES AGAINST ANY OTHER PARTY OR PARTIES, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS, OR OTHERWISE. THE COMPANY AND THE LENDER EACH AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS OR ANY PROVISION HEREOF OR THEREOF. THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS. SECTION 7.10 ENTIRE AGREEMENT. The Loan Documents reflect the entire agreement between the Company and the Lender with respect to the matters set forth herein and therein and supersede any prior agreements, commitments, drafts, communication, discussions and understandings, oral or written, with respect thereto. 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. SECTION 7.12 COUNTERPARTS. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute but one and the same agreement.

COSTS AND EXPENSES; INDEMNITY.

reasonable attorneys' fees and attorneys' fees incurred pursuant to Chapter 11 United States Code, which may be imposed on, incurred by, or asserted against any Indemnified Person, in any way relating to or arising out of this Agreement, including in connection with any infringement or alleged infringement with respect to any Intellectual Property Collateral, or any action taken or omitted to be taken by it hereunder (the "Indemnified Liabilities"); provided that Borrower shall not be liable to any Indemnified Person for any portion of such Indemnified Liabilities to the extent they are found by a final decision of a court of competent jurisdiction to have resulted from such Indemnified Person's gross negligence or willful misconduct.

AMERIGON INCORPORATED WARRANT TO PURCHASE COMMON STOCK This Warrant (this "Warrant") represents and certifies that, for value received, Big Beaver 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 Common Stock of Amerigon Incorporated, a California corporation (the "Company"), of an amount equal to eighteen percent (18%) of the principal amount of the Loan (as defined below) divided by the relevant Exercise Price specified in Section 2 hereof, as such Exercise Price may be adjusted from time to time pursuant to Section 5 hereof, at a purchase price per share equal to such Exercise Price, subject to the provisions and upon the terms and conditions hereinafter set forth. As used herein, the term "Loan" shall mean the One Million Five Hundred Thousand Dollars ($1,500,000) bridge facility to be advanced pursuant to the terms and conditions of the Credit Agreement dated as of September 20, 2001 (as amended, modified, renewed or extended from time to time, the "Credit Agreement") between the Company and the Holder. The date (if any) on which the Holder makes the first advance of proceeds under the Loan is referred to herein as the "Closing Date." As used herein, the term "Common Stock" shall mean the Company's presently authorized Common Stock, no par value, and any securities or other property into or for which such Common Stock may hereafter be converted or exchanged. As used herein, the term "Market Price of the Common Stock" shall mean (i) the average closing bid price of the Common Stock, for ten (10) consecutive business days ending on the Closing Date, as reported by Nasdaq, if the Common Stock is traded on the Nasdaq SmallCap Market, or (ii) the average last reported sale price of the Common Stock, for ten (10) consecutive business days ending on the Closing Date, as reported by the primary exchange on which the Common Stock is traded, if the Common Stock is traded on a national securities exchange, or by Nasdaq, if the Common Stock is traded on the Nasdaq National Market; provided, however, that such price shall not be greater than the average closing bid price or the

last reported sale price, as the case may be, for the ninety (90) calendar days ending on the Closing Date. 1. TERM OF WARRANT. 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 (5) years after such date (the "Warrant Term"). 2. EXERCISE PRICE. The "Exercise Price" shall be the Market Price of the Common Stock, provided that the Exercise Price shall be 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, a certificate or certificates for the shares of stock so purchased shall be delivered to the Holder within fifteen (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 fifteen (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: 2

X = Y --- B where: X = the number of shares of Common Stock to be issued to the Holder; Y = 18% of the principal amount of the Loan (i.e., 270,000); and B = the Exercise Price, as such price may be adjusted from time to time pursuant to Section 5 hereof. 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, a certificate or certificates for the shares of stock so converted shall be delivered to the holder hereof within fifteen (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 fifteen (15)-day period. 4. STOCK FULLY PAID; RESERVATION OF SHARES. All 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 liens, charges and United States taxes 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 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, during the Warrant Term, issues additional shares of Common Stock, or other securities exchangeable for, exercisable for, or convertible into additional shares of Common Stock, in each case in an equity offering in excess of One Million Five Hundred Thousand Dollars ($1,500,000), for consideration per share less than the Exercise Price, then and in such event, the per share Exercise Price 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, 3

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 two percent (2%) of the then outstanding 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 five percent (5%) of the then outstanding 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 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 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 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 Common Stock entitled to receive a dividend or other distribution payable in additional shares of Common Stock, then and in each such event the number of shares of Common Stock subject to this 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 (A) the numerator of which is the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date, and (B) the denominator of which shall be the total number of shares of 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 Common Stock issuable in payment of such dividend or distribution; and (ii) multiplying the number of shares of Common Stock subject to the Warrant by a fraction (A) the numerator of which is the total number of shares of 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 Common Stock issuable in payment of such dividend or distribution, and (B) the denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date. 4

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 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 Common Stock, or (ii) changes any 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 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 entity, 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 the Holder is or would be entitled by reason of its ownership of the shares underlying this Warrant shall be immediately subject to this 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 this Warrant shall remain the same as before such event. 6. NOTICE OF ADJUSTMENTS.

(a) All capitalized terms used in this Agreement and not otherwise defined herein shall have the meanings assigned to them in the Credit Agreement. (b) In this Agreement, (i) the meaning of defined terms shall be equally applicable to both the singular and plural forms of the terms defined, and (ii) the captions and headings are for convenience of reference only and shall not affect the construction of this Agreement.

SECTION 3. PLEDGE AND GRANT OF SECURITY INTEREST. (a) As additional security for the payment and performance of the Obligations by Borrower to Lender, Borrower hereby pledges, assigns, transfers and conveys and grants a continuing security interest in favor of Lender, for security purposes, in all of Borrower's right, title and interest in and to, whether now existing or hereafter from time to time acquired, as a member of BSST (collectively, the "LLC Collateral"), including, without limitation, (i) Borrower's Membership Interest (as defined in the LLC Agreement), (ii) two thousand (2,000) units of Series A Preferred Units (as defined in the LLC Agreement) (the "Pledged Units"), (iii) all dividends, distributions, instruments and other property of any kind from time to time received, receivable or otherwise distributed in respect of or in exchange therefor, and (iv) all proceeds of any of the foregoing. (b) This Agreement shall create a continuing security interest in the LLC Collateral, which shall remain in effect until terminated in accordance with the terms and conditions of this Agreement. SECTION 4. VOTING RIGHTS AND DISTRIBUTIONS (a) So long as no Event of Default shall have occurred and be continuing, Borrower shall be entitled to exercise all voting and other consensual rights, if any, for any purpose not inconsistent with the terms of this Agreement or any other Loan Documents. (b) So long as no Event of Default shall have occurred and be continuing, any and all Distributions (as defined in the LLC Agreement) and other proceeds pertaining to the LLC Collateral shall be delivered to Lender to be held in pledge hereunder and shall become part of the LLC Collateral. (c) Upon the occurrence and during the continuance of any Event of Default, (i) all rights of Borrower to exercise the voting and other consensual rights, if any, which Borrower would otherwise be authorized to exercise pursuant to Section 4(a) shall cease, and all such rights shall thereupon become vested in Lender who then shall have the sole right to exercise any such voting and other consensual rights, and (ii) Lender shall have the right to apply all Distributions and any cash so received to the Obligations. Effective upon the occurrence and during the continuance of an Event of Default, Borrower hereby grants to Lender an irrevocable proxy coupled with an interest for the LLC Collateral, pursuant to which proxy Lender shall be entitled to vote or consent with respect to the LLC Collateral in its sole discretion, as applicable.

SECTION 5. FURTHER ASSURANCES; APPOINTMENT OF LENDER AS ATTORNEY-IN-FACT. (a) With respect to the LLC Collateral, Borrower shall, if requested by Lender, cause BSST to duly authorize and execute, and deliver to Lender an agreement for the benefit of Lender pursuant to which, following the occurrence of and during the continuance of an Event of Default, BSST agrees to comply with any and all instructions regarding BSST originated by Lender without further consent by Borrower (or other registered owner) and not to comply with instructions regarding the LLC Collateral originated by any other Person other than a court of competent jurisdiction. (b) All certificates (if and when available) and instruments representing or evidencing any of the LLC Collateral shall be delivered to Lender in suitable form for transfer by delivery or shall be accompanied by duly executed instruments of transfer or assignment in blank, all in form and substance satisfactory to Lender. (c) Immediately and without further notice, upon the occurrence of and during the continuance of any Event of Default, Lender, at any time and at its sole discretion, may have any or all of the LLC Collateral registered in Lender's name or that of its nominee or nominees. (d) Borrower at its expense shall execute and deliver, or cause to be executed and delivered, to Lender any and all documents and instruments, in form and substance satisfactory to Lender, and take any and all action, which Lender may reasonably request from time to time, to perfect and continue perfected, maintain the priority of or provide notice of Lender's security interest in the LLC Collateral and to accomplish the purposes of this Agreement. Lender shall have the right to, in the name of Borrower, or in the name of Lender or otherwise, without notice to or assent by Borrower, and Borrower hereby irrevocably constitutes and appoints Lender (and any of Lender's officers or employees or agents designated by Lender) as Borrower's true and lawful attorney-in-fact with full power and authority, (i) to sign the name of Borrower on all or any of such documents or instruments and perform all other acts that Lender deems necessary or advisable in order to perfect or continue perfected, maintain the priority or enforceability of or provide notice of Lender's security interest in, the LLC Collateral, and (ii) to execute any and all other documents and instruments, and to perform any and all acts and things for and on behalf of Borrower, which Lender may deem necessary or advisable to maintain, preserve and protect the LLC Collateral and to accomplish the purposes of this Agreement, including, without limitation, (A) to defend, settle, adjust or (after the occurrence and during the continuance of any Event of Default) institute any action, suit or proceeding with respect to the LLC Collateral, and (B) after the occurrence and during the continuance of any Event of Default, to assign any and all of the LLC Collateral to any Person, including itself, without Borrower's written consent. The power of attorney set forth in this Section 4(d), being coupled with an interest, is irrevocable, so long as this Agreement shall not have terminated in accordance with Section 20. 3

(e) The foregoing shall in no way limit Lender's rights and remedies upon or after the occurrence and during the continuance of an Event of Default. SECTION 6. LENDER'S DUTIES. Notwithstanding any provision contained in this Agreement, Lender shall have no duty to exercise any of the rights, privileges or powers afforded to it and shall not be responsible to Borrower or any other Person for any failure to do so or delay in doing so. Except for the accounting for moneys actually received by Lender hereunder or in connection herewith, Lender shall have no duty or liability to exercise or preserve any rights, privileges or powers pertaining to the LLC Collateral. SECTION 7. REPRESENTATIONS AND WARRANTIES. Borrower represents and warrants to Lender that: (a) The Pledged Units are uncertificated, are duly authorized and fully paid, and constitute all of the issued and outstanding units of the Series A Preferred Units of BSST; (b) Borrower is the legal, record and beneficial owner of the Pledged Units and has good and marketable title thereto, free and clear of any lien, hypothecation, security interest, option or other charge or encumbrance, except for the security interest created by this Agreement, and has full right to pledge, assign, transfer and deliver the Pledged Units; (c) Borrower has full legal capacity, right, power and authority, without the consent of any other Person, to execute and deliver this Agreement, to pledge the LLC Collateral, and to carry out the transactions contemplated hereby; (d) This Agreement constitutes the legal, valid and binding obligation of Borrower, enforceable in accordance with its terms; and (e) With respect to the LLC Collateral and for the purposes of granting and perfecting the security interest provided herein, Borrower is not subject to laws of a jurisdiction other than the State of California. SECTION 8. COVENANTS. (a) Borrower will appear in and defend any action, suit or proceeding which may affect to a material extent its right, title or interest in the LLC Collateral. (b) Borrower will not sell, convey, transfer, or otherwise dispose of any LLC Collateral or any interest therein or create, incur or permit to exist any pledge, mortgage, lien, charge, security interest or other encumbrance with respect to the LLC Collateral or the proceeds thereof, other than that created hereby. (c) Borrower will deliver promptly to Lender any property received in exchange for or as a distribution on or with respect to the LLC Collateral (with any necessary endorsement), other than cash distributions. 4

(d) Borrower will promptly execute and deliver all further instruments and documents, and take all further action that may be necessary or desirable, or that Lender may request, in order to perfect and protect any security interest intended to be granted hereby or to enable Lender to exercise and enforce his rights and remedies hereunder with respect to any LLC Collateral. SECTION 9. LENDER'S RIGHTS AND REMEDIES. (a) Lender shall have all rights and remedies available to it under this Agreement, the Security Agreement, the other Loan Documents and applicable law with respect to the security interests in any of the LLC Collateral or any other collateral. Borrower agrees that such rights and remedies include, but are not limited to, the right of Lender as a secured party to sell or otherwise dispose of Borrower's collateral after any Event of Default pursuant to the UCC (as such term is defined in the Security Agreement). (b) The cash proceeds actually received from the sale or other disposition or collection of LLC Collateral, and any other amounts received in respect of the LLC Collateral the application of which is not otherwise provided for herein, shall be applied as provided in the Security Agreement. (c) Each right, power and remedy of Lender provided for in this Agreement, other Loan Documents, or any related agreement now or hereafter existing at law or in equity or by statute or otherwise shall be cumulative and concurrent and shall be in addition to every other such right, power or remedy. SECTION 10. PRIVATE SALE. In view of the fact that federal and state securities laws may impose certain restrictions upon the method by which a sale of Pledged Units may be effected, it is agreed that upon and after an Event of Default, Lender may from time to time attempt to sell all or any part of the LLC Collateral by means of a private sale, restricting the bidders and prospective purchasers to those who will represent and agree that they are purchasing for investment only and not for distribution. Borrower acknowledges that such private sales may be at prices and on terms less favorable to the seller than if the LLC Collateral were sold at a public sale and that the Lender has no obligation to delay the sale of any LLC Collateral to permit the registration of the LLC Collateral for public sale under any securities law. SECTION 11. NOTICES. All notices or other communications hereunder shall be given in the manner and to the addresses specified in the Credit Agreement. All such notices and other communications shall be effective (i) if delivered by hand, when delivered; (ii) if sent by mail, upon the earlier of the date of receipt or five Business Days after deposit in the mail, first class (or air mail, with respect to communications to be sent to or from the United States); and (iii) if sent by facsimile transmission, when sent. SECTION 12. NO WAIVER; CUMULATIVE REMEDIES. No failure on the part of Lender to exercise, and no delay in exercising, any right, remedy, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, remedy, power or privilege preclude any other or further exercise thereof or the exercise of any 5

other right, remedy, power or privilege. The rights and remedies under this Agreement are cumulative and not exclusive of any rights, remedies, powers and privileges that may otherwise be available to Lender. SECTION 13. COSTS AND EXPENSES; INDEMNITY. (a) Borrower agrees to pay on demand all costs and expenses of Lender, including without limitation all reasonable attorneys' fees, in connection with the enforcement or attempted enforcement of, and preservation of any rights or interests under, this Agreement, and the assignment, sale or other disposal of any of the LLC Collateral. (b) Borrower hereby agrees to indemnify Lender and any of its affiliates, and their respective directors, officers, employees, agents, counsel and other advisors (each an "Indemnified Person") against, and hold each of them harmless from, any and all liabilities, obligations, losses, claims, damages, demands, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever, including, without limitation, reasonable attorneys' fees and attorneys' fees incurred pursuant to Chapter 11 United States Code, which may be imposed on, incurred by, or asserted against any Indemnified Person, in any way relating to or arising out of this Agreement, including in connection with any infringement or alleged infringement with respect to any LLC Collateral, or any action taken or omitted to be taken by it hereunder (the "Indemnified Liabilities"); provided that Borrower shall not be liable to any Indemnified Person for any portion of such Indemnified Liabilities to the extent they are found by a final decision of a court of competent jurisdiction to have resulted from such Indemnified Person's gross negligence or willful misconduct. If and to the extent that the foregoing indemnification is for any reason held unenforceable, Borrower agrees to make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law. (c) Any amounts payable to Lender under this Section 13 or otherwise under this Agreement if not paid upon demand shall bear interest from the date of such demand until paid in full, at the rate of interest set forth in the Note.

Borrower shall not have the right to assign its rights or obligations or any interest herein without the prior written consent of Lender. Lender reserves the right freely to sell, assign, transfer or grant participations in all or any portion of Lender's rights and obligations hereunder (i) to one or more Affiliates of Lender and/or (ii) with the prior consent of Borrower (which consent shall not be unreasonably withheld) to any other Person. SECTION 15. GOVERNING LAW. This Agreement shall be governed by, and construed in accordance with, the law of the State of California, except as required by mandatory provisions of law and to the extent the validity or perfection of the security interests hereunder, or the remedies hereunder, in respect of any LLC Collateral are governed by the law of a jurisdiction other than California. 6

SECTION 16. AMENDMENT. This Agreement and the other Loan Documents contain the entire agreement of the parties with respect to the subject matter hereof and shall not be amended except by the written agreement of the parties as provided in the Credit Agreement. SECTION 17. SEVERABILITY. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under all applicable laws and regulations. If, however, any provision of this Agreement 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 this Agreement, or the validity or effectiveness of such provision in any other jurisdiction. SECTION 18. COUNTERPARTS. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. SECTION 19. INCORPORATION OF PROVISIONS OF THE CREDIT AGREEMENT. To the extent the Credit Agreement contains provisions of general applicability to the Loan Documents, such provisions are incorporated herein by this reference. SECTION 20. TERMINATION. Upon payment and performance in full of all Obligations, this Agreement shall terminate and Lender shall promptly execute and deliver to Borrower such documents and instruments reasonably requested by Borrower as shall be necessary to evidence termination of all security interests given by Borrower to Lender hereunder; provided, however, that (i)the obligations of Borrower under Section 13 hereof shall survive such termination and (ii) in the event a voluntary proceeding in bankruptcy is filed by Borrower or an involuntary proceeding in bankruptcy is filed against Borrower, this Agreement and Lender's interest in the LLC Collateral created hereby shall survive such proceeding. SECTION 21. SECURITY AGREEMENT. Borrower acknowledges that the rights and remedies of Lender with respect to the security interests in the LLC Collateral granted hereby may be more fully set forth in the Security Agreement and the other Loan Documents, and all such rights and remedies are cumulative. SECTION 22. NO INCONSISTENT REQUIREMENTS. Borrower acknowledges that this Agreement and the Security Agreement may contain covenants and other terms and provisions variously stated regarding the same or similar matters, and Borrower agrees that all such covenants, terms and provisions are cumulative and all shall be performed and satisfied in accordance with their respective terms.
