The Company has the power to own or lease its properties and assets and to carry on its business as now being conducted. The Company is duly qualified to do business and is in good standing in California, which is the 3

only jurisdiction in which the character or location of the properties owned or leased by the Company or the nature of the business conducted by the Company makes such qualification necessary. However, the failure to be so qualified or in good standing in any given jurisdiction will not be deemed to be a breach of this Section 2.1 unless the failure of the Company to be in good standing in any such jurisdiction individually or in all such jurisdictions collectively has or is likely to have a material adverse effect on the Company or on the transactions contemplated herein. 2.2 Capital Stock.

Annexed hereto as Schedule 2.3 is the unaudited consolidated balance sheet of the Company (the "Financial Statements") as of March 31, 2004 (the "Balance Sheet Date"). The Financial Statements were carefully prepared from the books and records of the Company, and although the Financial Statements are not audited and do not contain the footnotes which would be required in audited financial statements, present fairly the financial position, assets and liabilities of the Company and the results of its operations, on a cash basis for the respective periods indicated applying accounting principles on a consistent basis. The Company maintains accurate books and records reflecting its assets and liabilities and maintains proper and adequate internal accounting controls which provide assurance that (i) transactions are executed with management's authorization; (ii) transactions are recorded as necessary to maintain accountability for the Company's consolidated assets; (iii) access to the Company's assets is permitted only in accordance with management's authorization; (iv) the reporting of the Company's assets is compared with existing assets at regular intervals; and (v) accounts, notes and other receivables and inventory are recorded accurately, and proper and adequate procedures are implemented to effect the collection thereof on a current and timely basis.

results of operations or prospects, of the Company and to the best knowledge, information and belief of the Shareholders, no fact or condition exists or is contemplated or threatened which might cause such a change in the future. 2.4 Books and Records.

It is the desire and intent of the parties to this Agreement that the provisions of Section 7.1 shall be enforced to the fullest extent permissible under the laws and public policies applied in each jurisdiction in which enforcement is sought. If any particular provisions or portion of Section 7.1 shall be adjudicated to be invalid or unenforceable, for any reason, including, without limitation, the geographic or business scope or duration thereof, such provision shall be construed in such a way as to make it valid and enforceable to the maximum extent possible.

Accordingly, each Shareholder agrees that in such event, in addition to any other remedies which the Company and/or Purchaser may have in law or equity for money damages or other relief, the Company and the Purchaser shall be entitled to temporary and/or injunctive relief, without the necessity of posting a bond therefor or of proving damages, to enforce the provisions hereof.

8.1. Conduct of Business of the Company. During the period from the date of this Agreement to the Closing Date, the Shareholders shall cause the Company and each of its subsidiaries to conduct their respective operations only according to their ordinary and usual course of business and to use their best efforts to preserve intact their respective business organizations, keep available the services of their officers and employees and maintain satisfactory relationships with licensors, suppliers, distributors, clients and others having business relationships with them. Notwithstanding the immediately preceding sentence, prior to the Closing Date, except as may be first approved by the Purchaser or as is otherwise permitted or required by this Agreement, the Shareholders will cause (a) the Company's and each of its subsidiaries' respective Certificate of Incorporation and By-Laws to be maintained in their form on the date of this Agreement, (b) the compensation payable or to become payable by the Company and each of its subsidiaries to any officer, employee or agent on the Balance Sheet Date to be maintained at their levels on the date of this Agreement, (c) the Company and each of its subsidiaries to refrain from making any bonus, pension, retirement or insurance payment or arrangement to or with any such persons except those that may have already been accrued, (d) the Company and each of its subsidiaries to refrain from entering into any contract or commitment except contracts in the ordinary course of business, (e) the Company and each of its subsidiaries to refrain from making any change affecting any bank, safe deposit or power of attorney arrangements of the Company or any such subsidiary and (f) the Company and each of its subsidiaries to refrain from taking any of the actions referred to in Section 2.17 hereof.

During the period from the date of this Agreement to the Closing Date, the Shareholders shall cause the Company to confer on a regular and frequent basis with one or more designated representatives of the Purchaser to report material operational matters and to report the general status of ongoing operations.

Further Review. Shareholders and the Purchaser may, prior to the Closing Date, through their representatives, review the properties, books and records of the Company or Purchaser, respectively, and each of its subsidiaries 28

and its financial and legal condition as they deem necessary or advisable to familiarize themselves with such properties and other matters; such review shall not, however, affect the representations and warranties made by the other party hereunder or the remedies of the reviewing party for breaches of those representations and warranties. The Shareholders shall cause the Company and each of its subsidiaries to, and Purchaser shall permit, after the date of execution of this Agreement, full access to the premises and to all the books and records of the Purchaser and Company, respectively, and their subsidiaries and to cause the officers of the Purchaser and Company and each of their subsidiaries to furnish the reviewing party and their representatives with such financial and operating data and other information with respect to the business and properties of the Purchaser or Company, as the case may be, and their subsidiaries as the reviewing party shall from time to time reasonably request. In the event of termination of this Agreement, the reviewing party shall keep confidential any material information obtained from the Purchaser, the Shareholders or the Company or any subsidiary concerning respective properties, operations and business (unless readily ascertainable from public or published information or trade sources) until the same ceases to be material (or becomes so ascertainable) and, at the request of the reviewed party, shall return to the reviewed party and its subsidiaries all copies of any schedules, statements, documents or other written information obtained in connection therewith. The reviewed party shall deliver or cause to be delivered such additional instruments as the reviewing party may reasonably request for the purpose of consummating the transactions contemplated by this Agreement.

The respective representations, warranties, covenants and agreements of the Shareholders, the Company and the Purchaser contained in this Agreement, or any Schedule attached hereto or any agreement or document delivered pursuant to this Agreement shall survive for a period of one year from the consummation of the transactions contemplated hereby; provided, however, that the representations, warranties and agreements made with regard to taxes and ERISA matters shall survive until the applicable statutes of limitations have expired. 9.2 Indemnification. (a) The Shareholders agree to indemnify and hold the Purchaser and their officers, directors, shareholders, employees, affiliates and agents harmless from damages, losses, liabilities, assessments, judgments, costs or expenses (including, without limitation, penalties, interest and reasonable counsel fees and expenses), (each a "Claim"), in excess of $25,000 in the aggregate, as a result of or arising out of the material breach of any representation or warranty made by the Shareholders and the Company, or the failure of any material representation or warranty made by the Shareholders and the Company in this Agreement or in any Schedule attached hereto 29

or any document or agreement delivered hereunder to be true and correct in all material respects as of the date of this Agreement and as of the Closing Date. (b) The Purchaser agrees to indemnify and hold the Shareholders and each of their officers, directors, shareholders, employees, affiliates and agents harmless from damages, losses or expenses (including, without limitation, reasonable counsel fees and expenses) in excess of $25,000, in the aggregate, suffered or paid, directly or indirectly, as a result of or arising out of the failure of any representation or warranty made by the Purchaser in this Agreement to be true and correct in all respects as of the date of this Agreement and as of the Closing Date. 9.3 Conditions of Indemnification. (a) A party entitled to indemnification hereunder (the "Indemnified Party") shall notify the party or parties liable for such indemnification (the "Indemnified Party") in writing of any Claim or potential liability for Taxes ("Tax Claim") which the Indemnified Party has determined has given or could give rise to a right of indemnification under this Agreement. Such notice shall be given within a reasonable (taking into account the nature of the Claim or Tax Claim) period of time after the Indemnified Party has actual knowledge thereof. The Indemnifying Party shall satisfy its obligations under this Article 8 within forty days after receipt of subsequent written notice from the Indemnified Party if an amount is specified therein, or promptly following receipt of subsequent written notice or notices specifying the amount of such Claim or Tax Claim additions thereto; provided, however, that for so long as the Indemnifying Party is in good faith defending a Claim or Tax Claim pursuant to Section 9.3(b) hereof, its obligation to indemnify the Indemnified Party with respect thereto shall be suspended (other than with respect to any costs, expenses or other liabilities incurred by the Indemnified Party prior to the assumption of the defense by the Indemnifying Party). Failure to provide a notice of Claim or Tax Claim within the time period referred to above shall not constitute a defense to a Claim or Tax Claim or release the Indemnifying Party from any obligation hereunder to the extent that such failure does not prejudice the position of the Indemnifying Party. (b) If the facts giving rise to any such indemnification involve any actual, threatened or possible Claim or demand or Tax Claim by any person not a party to this Agreement against the Indemnified Party, the Indemnifying Party shall be entitled to contest or defend such Claim or demand Tax Claim at its expense and through counsel of its own choosing, which counsel shall be reasonably acceptable to the Indemnified Party, such right to contest or defend shall only apply if the 30

Indemnifying Party gave written notice of its intention to assume the contest and defense of such Claim or demand Tax Claim to the Indemnified Party as soon as practicable, but in no event more than thirty days after receipt of the notice of Claims or Tax Claim, and provided the Indemnified Party with appropriate assurances as to the creditworthiness of the Indemnifying Party, and that the Indemnifying Party will be in a position to pay all fees, expenses and judgments that might arise out of such Claim or demand Tax Claim. The Indemnified Party shall have the obligation to cooperate in the defense of any such Claim or demand Tax Claim and the right, at its own expense, to participate in the defense of any Claim or Tax Claim. So long as the Indemnifying Party is defending in good faith any such Claim or demand Tax Claim asserted by a third party against the Indemnified Party, the Indemnified Party shall not settle or compromise such Claim or demand Tax Claim. The Indemnifying Party shall have the right to settle or compromise any such Claim or demand Tax Claim without the consent of the Indemnified Party at any time utilizing its own funds to do so if in connection with such settlement or compromise the Indemnified Party is fully released by the third party and is paid in full any indemnification amounts due hereunder. The Indemnified Party shall make available to the Indemnifying Party or its agents all records and other materials in the Indemnified Party's possession reasonably required by it for its use in contesting any third party Claim or demand Tax Claim and shall otherwise cooperate, at the expense of the Indemnifying Party, in the defense thereof in such manner as the Indemnifying Party may reasonably request. Whether or not the Indemnifying Party elects to defend such Claim or demand Tax Claim, the Indemnified Party shall have no obligation to do so. 9.4 Limitations on Indemnification for Breaches of Representations and Warranties. Notwithstanding anything contained in this Agreement to the contrary, (a) the individual liability of the Shareholders under Section 9.2 for any liability arising as a result of the failure of Shareholders' or Company's representations and warranties to be true and correct or arising for any other reason under Section 9.2(a), shall not exceed the number of Escrowed Shares multiplied by the $.95 (the "Closing Value") and the cancellation of the Escrowed Shares shall be the sole remedy of Purchaser in respect of such indemnification; and (b) the aggregate liability of Purchaser and its affiliates under Section 9.2(b) for any liability arising as a result of the failure of Purchaser's representations and warranties to be true and correct, shall not exceed the number of Contingent Shares multiplied by the Closing Value and the release of Contingent Shares form escrow to Shareholders shall be the sole remedy in respect of such indemnification. 9.5 Payment of Indemnification Liabilities. (a) At the sole discretion of the indemnifying party, payments of claims to an indemnified party may be made by wire transfer of immediately available funds within 10 business days after the date of the notice of sums due and owing provided for in Section 9.2, in lieu of the release of shares from the Purchaser or Shareholder Escrows. 31

(b) In the event that Purchaser, in accordance with Section 9.5(a), does not elect to pay any liabilities owing by it by wire transfer, the number of Contingent Shares to be released with respect to any such liability shall be determined by dividing the amount of such liability by $.95 and multiplying the result thus obtained by 1.15. (c) In the event that a Shareholder does not elect to pay liabilities owing by wire transfer, the number of Escrowed to be released from Escrow to Purchaser with respect to such liability and to be cancelled shall be determined by dividing the amount of such liability by $.95.
