NOW, THEREFORE, in consideration of the foregoing premises and the mutual representations, warranties and covenants herein contained, the Parties agree as follows:

1. Definitions. The defined terms used in this Agreement are set forth in the Glossary attached hereto as Exhibit A.

2. Purchase and Sale of the Shares.

(a) Basic Transaction. On and subject to the terms and conditions of this Agreement, Buyer agrees to purchase from Seller, and Seller agrees to sell to Buyer, the Shares for an aggregate price of Eight Million Dollars ($8,000,000) (the “Purchase Price”), and other good and valuable consideration, subject to adjustment as provided in Section 2(e) below.

(b) Purchase Price Payment. At the Closing, Buyer shall pay to Seller the Purchase Price by wire transfer of immediately available funds to an account identified by Seller in writing prior to the Closing.

business day following the satisfaction or waiver of all conditions to the obligations of the Parties to consummate the transactions contemplated hereby (other than conditions with respect to actions the respective Parties will take at the Closing itself) or such other date as Buyer and Seller may mutually determine (the “Closing Date”).

(d) Deliveries at Closing. At the Closing: (i) Seller shall deliver to Buyer the various certificates, instruments and documents referred to in Section 6(a) below; (ii) Buyer shall deliver to Seller the various certificates, instruments and documents referred to in Section 6(b) below; (iii) Seller shall deliver to Buyer the stock certificate(s) for the Shares, together with an assignment of certificate with respect to the Shares; and (iv) Buyer shall deliver to Seller the Purchase Price as provided in Section 2(b) above.

(e) Purchase Price Adjustments.

(i) Pre-Closing Adjustment.

(A) Preparation of Estimated Closing Balance Sheet. At least two (2) business days before the Closing, Buyer shall prepare and deliver to Seller an estimated balance sheet of the Company dated as of the Closing Date prepared on the same basis as the Financial Statements (the “Estimated Closing Balance Sheet”) and a calculation based upon the Estimated Closing Balance Sheet of the sum of (1) cash and cash equivalents (including marketable securities and short term investments) minus Four Hundred Fifty Thousand Dollars ($450,000), plus (2) accounts receivable aged less than ninety (90) days (excluding intercompany accounts receivable), plus (3) inventory and minus (4) current liabilities (excluding intercompany accounts payable and the current portion of the Company’s long term debt), as well as a consideration of any agreed-upon unbooked period-end adjustments (the “Estimated Closing Working Capital Amount”).

(B) Adjustment to Purchase Price. No later than fifteen (15) business days prior to the Closing, the Parties shall agree to a working capital amount determined as described in Section 2(e)(i)(A) above for the Estimated Closing Working Capital Amount but using the Most Recent Financial Statements with the Most Recent Fiscal Month-End as the date for the determination (the “5/31/07 Working Capital Amount”). At the Closing, the Estimated Closing Working Capital Amount shall be compared to 5/31/07 Working Capital Amount. If the 5/31/07 Working Capital Amount is greater than the Estimated Closing Working Capital Amount, then an immediate downward adjustment equal to such amount shall be made on a dollar-for-dollar basis to the Purchase Price. If the Estimated Closing Capital Amount is greater than the 5/31/07 Working Capital Amount, then an immediate upward adjustment equal to such amount shall be made on a dollar-for-dollar basis in the Purchase Price.

(ii) Post-Closing Adjustment.

(A) Preparation of Preliminary Closing Balance Sheet. As soon as reasonably possible after the Closing Date but not later than sixty (60) days thereafter, Buyer shall prepare and deliver to Seller a balance sheet of the Company dated as of the Closing Date prepared in accordance with GAAP applied on a basis consistent with the preparation of the Financial Statements (the “Preliminary Closing Balance Sheet”) and a working capital amount

determined as described in Section 2(e)(i)(A) above for the Estimated Closing Working Capital Amount but using the Preliminary Closing Balance Sheet with the Closing Date as the date for the determination.

(B) Review of Preliminary Closing Balance Sheet. The Preliminary Closing Balance Sheet shall be binding and conclusive upon, and deemed accepted by, Seller unless Seller has notified Buyer in writing of any objections thereto consistent with the provisions of this Section 2(e)(ii)(B) within thirty (30) days after receipt thereof. Otherwise, during the thirty (30)-day period after Seller’s receipt of the Preliminary Closing Balance Sheet and, as applicable, thereafter, Buyer shall make the work papers and back-up materials used in preparing the Preliminary Closing Balance Sheet, as well as the personnel of Buyer and the Company with knowledge regarding any underlying matters, available to Seller at reasonable times and upon reasonable notice. Any written notice by Seller under this Section 2(e)(ii)(B) shall (1) specify in reasonable detail each item on the Preliminary Closing Balance Sheet that Seller disputes and (2) include a summary of Seller’s reasons for such dispute.

(C) Disputes. Disputes between Buyer and Seller relating to the Preliminary Closing Balance Sheet that cannot be resolved by them within thirty (30) days after receipt by Buyer of the notice referred to in Section 2(e)(ii)(B) above may be referred no later than forty-five (45) days after such receipt for decision (at the request of either Buyer or Seller) to Singer Lewak Greenbaum & Goldstein, CPAs, Los Angeles, California (“Singer”). If Singer is unavailable, then Buyer and Seller shall select an independent nationally recognized accounting firm to decide the matter (Singer or such other firm, the “Auditor”). Prior to referring the matter to the Auditor, Buyer and Seller shall agree on the procedures to be followed by the Auditor (including procedures with regard to presentation of evidence). Such procedures shall not alter the accounting practices, principles and policies to be applied to the Preliminary Closing Balance Sheet, which shall be those required by this Agreement. If Buyer and Seller are unable to agree upon procedures before the end of thirty (30) days after referral of the dispute to the Auditor, then the Auditor shall establish such procedures giving due regard to the intention of the Parties to resolve disputes as quickly, efficiently and inexpensively as possible, which procedures may, but need not, be those proposed by either of Buyer or Seller. Buyer and Seller shall then submit evidence in accordance with the procedures established, and the Auditor shall decide the dispute in accordance therewith. The Auditor’s decision on any matter referred to it shall be final and binding on Seller and Buyer. The fee of the Auditor shall be borne by Seller, on the one hand, and Buyer, on the other hand, in equal portions, unless the Auditor decides, based on its determination with respect to the reasonableness of the respective positions of Buyer and Seller, that the fee shall be borne in unequal proportions.

(D) Final Closing Balance Sheet. The Preliminary Closing Balance Sheet shall become final and binding upon Buyer and Seller upon the earlier of: (1) the failure by Seller to object thereto within the period permitted under Section 2(e)(ii)(B) above; (2) the agreement between Buyer and Seller with respect thereto; or (3) the decision by the Auditor with respect to any disputes under Section 2(e)(ii)(C) above. As adjusted, if applicable, pursuant to such agreement or such decision, the Preliminary Closing Balance Sheet, when final and binding, is referred to herein as the “Final Closing Balance Sheet.”

(E) Adjustment to Purchase Price. As soon as practicable

(but not more than five (5) business days) after the determination of the Final Closing Balance Sheet in accordance with Section 2(e)(ii)(D) above, a working capital amount (the “Final Closing Working Capital Amount”) shall be determined as described in Section 2(e)(i)(A) above using the Final Closing Balance Sheet for such calculation and such amount shall be compared with the Estimated Closing Working Capital Amount. If the Final Closing Working Capital Amount is less than the Estimated Closing Working Capital Amount, then an amount equal to the difference shall be paid on a dollar-for-dollar basis by Seller to Buyer in immediately available funds. If the Final Closing Working Capital Amount is more than the Estimated Closing Working Capital Amount, then an amount equal to the difference shall be paid (on a dollar-for-dollar basis) by Buyer to Seller in immediately available funds.

8. Tax Matters. The following provisions shall govern the allocation of responsibility as between Buyer and Seller for certain Tax matters following the Closing Date:

(a) Tax Indemnification. Seller shall indemnify Buyer and hold Buyer harmless from and against (without duplication) any loss, claim, Liability, expense or other damage directly attributable to: (i) Taxes (or the non-payment thereof) of the Company for all Taxable periods beginning on March 22, 2004 and ending on or before the Closing Date and the portion through the end of the Closing Date of any taxable period that includes (but does not end on) the Closing Date (the “Pre-Closing Tax Period”); (ii) any and all Taxes of any member of an affiliated, consolidated, combined or unitary group of which the Company is or was a member beginning on March 22, 2004 and ending on or prior to the Closing Date, including pursuant to Treasury Regulation §1502-6 or any corresponding provision in state, local or foreign law; and (iii) Taxes of any person (other than the Company) imposed on the Company as a transferee or successor, by contract or pursuant to any law, rule or regulation, which Taxes relate to an event or transaction occurring beginning on March 22, 2004 and occurring on or before the Closing Date; provided, however, that Seller shall be liable under this Section 8(a) only to the extent that such Taxes exceed the amount, if any, reserved for Taxes (excluding any reserve for deferred Taxes established to reflect timing differences between book and Tax income) in the Final Closing Balance Sheet and taken into account in determining any Purchase Price adjustment pursuant to Section 2(e)(ii) above. Seller shall reimburse Buyer for any Taxes of Company that are the responsibility of Seller pursuant to this Section 8(a) within fifteen (15) business days after payment of such Taxes by Buyer.

(b) Audits. Seller shall allow Buyer and the Company and their counsel to participate at Buyer’s and the Company’s expense in any audit of Seller’s consolidated federal Income Tax Returns to the extent such returns relate directly to the Company. Seller shall not settle any such audit in a manner that would adversely affect the Company after the Closing Date without the prior written consent of Buyer, which consent shall not be unreasonably withheld.

(c) Straddle Period. In the case of any Taxable period that includes (but does not end on) the business day prior to the Closing Date (a “Straddle Period”), the amount of any Taxes based on or measured by income or receipts of the Company for the Pre-Closing Tax

Period shall be determined based on an interim closing of the books as of the close of business on the Closing Date (and for such purpose, the Taxable period of any partnership or other pass-through entity in which the Company holds a beneficial interest shall be deemed to terminate at such time) and the amount of other Taxes of the Company for a Straddle Period that relate to the Pre-Closing Tax Period shall be deemed to be the amount of such Tax for the entire Taxable period multiplied by a fraction the numerator of which is the number of days in the Taxable period ending on the Closing Date and the denominator of which is the number of days in such Straddle Period.

(d) Responsibility for Filing Tax Returns. Seller shall include the income of the Company (including any deferred items triggered into income by Treasury Regulation §1.1502-13 and any excess loss account taken into income under Treasury Regulation §1.1502-19) on Seller’s consolidated federal Income Tax Returns for all periods through the end of the Closing Date and pay any federal Income Taxes attributable to such income. Buyer shall (and Buyer shall, following the Closing, cause the Company to) furnish Tax information to Seller for inclusion in Seller’s federal consolidated Income Tax Return for the period that includes the Closing Date in accordance with the Company’s past custom and practice. For all tax periods ending on or before the Closing Date, Seller shall cause the Company to join in Seller’s consolidated federal Income Tax Return and, in jurisdictions requiring separate reporting from Seller, to file separate state and local Income Tax Returns. All such Income Tax Returns shall be prepared and filed in a manner consistent with prior practice, except as required by a change in applicable law. Buyer shall cause the Company to file Tax Returns for all periods other than periods ending on or before the Closing Date; provided, however, that no such Tax Return as to which Seller may have any liability shall be filed (i) until Seller has had the opportunity, for at least twenty (20) business days to review such Tax Return and (ii) without incorporation of such changes thereto as Seller may reasonably request (so long as the same are consistent, to the extent applicable, with the past practice of the Company).

(e) Cooperation on Tax Matters.

(i) The Parties shall cooperate fully (and Buyer shall, following the Closing, cause the Company to cooperate fully) to the extent reasonably requested by any Party in connection with the filing of any Tax Returns as to which Seller may have any liability under this Section 8 and any audit, litigation or other proceeding with respect to Taxes payable with respect thereto. Such cooperation shall include the retention and (upon another Party’s request) the provision of records and information that are reasonably relevant to any such Tax Return, audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Parties agree (and Buyer shall, following the Closing, cause the Company) to (A) retain all books and records with respect to Tax matters pertinent to the Company relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and any extensions thereof) of the respective taxable periods and abide by all record retention agreements entered into with any taxing authority and (B) give each other reasonable written notice prior to transferring, destroying or discarding any such books and records and, if a Party so requests, allowing such Party to take possession of such books and records.

(ii) Buyer and Seller further agree (and Buyer shall, following the

Closing, cause the Company), upon request, to (A) use their commercially reasonable efforts to obtain any certificate or other document from any governmental authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including with respect to the transactions contemplated hereby) and (B) provide any Party with all information that such Party may be required to report pursuant to Code Section 6043 and all Treasury Regulations promulgated thereunder.

(f) Tax Sharing Agreements. Seller shall cause (i) all Tax sharing agreements or similar agreements with respect to or involving the Company to be terminated as of the business day prior to the Closing Date and, (ii) thereafter, the Company not to be bound thereby or to have any Liability thereunder for past, present or future Taxes.

(g) Responsibility for Certain Taxes and Fees. All transfer, documentary, sales, use, stamp, registration and other such Taxes and all conveyance fees, recording charges and other fees and charges (including any penalties and interest) incurred by the Parties or the Company in connection with consummation of the transactions contemplated by this Agreement shall be shared and paid equally by the Parties when due, and the Parties shall file all necessary Tax Returns and other documentation with respect to all such Taxes, fees and charges at their own respective expense. If required by applicable law, the Parties shall join in the execution of any such Tax Returns and other documentation.

(h) Code Section 338(h)(10) Election. Buyer and Seller shall join in making an election under Code Section 338(h)(10) (and any corresponding elections under state, local or foreign Tax law) or any similar Tax election in connection with the purchase of the Shares. Seller will pay any Tax attributable to such election and will indemnify Buyer and the Company against Adverse Consequences arising out of any failure to pay such Tax. The Parties agree that the Purchase Price and the liabilities of the Company (plus other relevant items) will be allocated to the assets of the Company for all purposes (including Tax and financial accounting purposes) in a manner consistent with Code Sections 338 and 1060 and the Treasury Regulations thereunder. Buyer, Seller and the Company shall file all Tax Returns (including amended returns and claims for refund) and information reports in a manner consistent with such values. The Parties shall cooperate fully with each other in connection with the making any such election.

9. Employee Benefits. Seller shall take all action and do all things necessary after the Closing to permit an employee of the Company as of the Closing Date to submit claims for benefits under the provisions of Seller’s Employee Welfare Benefit Plans for which such employee was eligible, it being understood that such claims must be timely submitted in accordance with, and are subject to, the applicable terms and conditions of such Employee Welfare Benefit Plans. Buyer shall (and Buyer shall, following the Closing, cause the Company to) after the Closing inform employees of the Company as of the Closing Date that they should submit such claims as soon as possible following the Closing Date. Seller shall be responsible after the Closing for any filing with any government or governmental agency required by applicable law with respect to such Employee Welfare Benefit Plans. Buyer shall (and Buyer shall, following the Closing, cause the Company to) after the Closing cooperate fully with Seller in providing information for such filings. Each Party shall indemnify the other Party and hold the other Party harmless from and against (without duplication) any loss, claim, Liability, expense or other damage directly attributable to any breach of its obligations under this Section 9.

10. Termination.

(a) Termination of Agreement. Certain of the Parties may terminate this Agreement as provided below:

(i) Buyer and Seller may terminate this Agreement by mutual written consent at any time prior to the Closing;

(ii) Buyer may terminate this Agreement by giving written notice to Seller at any time prior to the Closing in the event (A) Seller has within the then previous five (5) business days given Buyer any notice pursuant to Section 5(e) above and (B) the development that is the subject of such notice has had a Material Adverse Effect;

(iii) Buyer may terminate this Agreement by giving written notice to Seller at any time prior to the Closing in the event (A) Seller has breached any material representation, warranty or covenant contained in this Agreement in any material respect, Buyer has notified Seller of such breach and such breach has continued without cure for a period of thirty (30) days after such notice, it being understood that this right shall not apply to any breach of any representations or warranties set forth in Section 4 above if Buyer Knew that such representations or warranties were breached by Seller, or (B) the Closing has not occurred on or before October 1, 2007, by reason of the failure of any condition precedent under Section 6(a) above (unless the failure results primarily from Buyer itself breaching any representation, warranty or covenant contained in this Agreement); and

(iv) Seller may terminate this Agreement by giving written notice to Buyer at any time prior to the Closing in the event (A) Buyer has breached any material representation, warranty or covenant contained in this Agreement in any material respect, Seller have notified Buyer of such breach and such breach has continued without cure for a period of thirty (30) days after such notice or (B) the Closing has not occurred on or before October 1, 2007, by reason of the failure of any condition precedent under Section 6(b) above (unless the failure results primarily from Seller itself breaching any representation, warranty or covenant contained in this Agreement).

The Parties agree and acknowledge that it would be extremely difficult to calculate with precision Seller’s actual damages resulting from such termination and that the Break-up Fee constitutes the Parties’ good faith effort to arrive at appropriate liquidated damages for such termination and does not constitute a penalty.

(c) Amount Payable by Seller. If this Agreement is terminated by Buyer pursuant to Section 10(a)(ii) above or Section 10(a)(iii) above or by Seller pursuant to Section 10(a)(iv)(B) above by reason of the failure of the condition precedent under Section 6(b)(vi) above (i.e., the condition precedent of approval of this Agreement and the transactions contemplated hereby by the shareholders of Seller), then Seller shall reimburse Buyer for the amount of all out-of-pocket expenses reasonably incurred by Buyer through the date of such

termination related to this Agreement and the transactions contemplated hereby (the “Expenses”) within two (2) business days of Seller’s receipt from Buyer of reasonable supporting documentation for the Expenses by check or wire transfer of same day funds.

(d) Effect of Termination. If this Agreement is terminated pursuant to Section 10(a) above, all rights and obligations of the Parties hereunder shall terminate without any liability of any Party to any other Party (except for any liability of any Party then in breach of a covenant contained in this Agreement and, if applicable, Buyer’s obligation to pay to Seller the Break-up Fee pursuant to Section 10(b) above or Seller’s obligation to reimburse Buyer for the Expenses pursuant to Section 10(c) above); provided, however, that this Section 10(d), Section 11 and the Confidentiality Agreement shall survive any termination of this Agreement.

11. Miscellaneous.

(a) Public Announcements. No Party shall issue any press release or make any public announcement relating to this Agreement or its subject matter without the prior written approval of the other Party; provided, however, that (i) Seller may make any public disclosure in accordance with Section 5(a) and (ii) any Party may make any public disclosure it believes in good faith is required by applicable law or any listing or trading agreement concerning its publicly-traded securities (in which case the disclosing Party shall use its commercially reasonable efforts to advise the other Parties prior to making the disclosure).

(d) Succession and Assignment. This Agreement shall be binding upon and inure to the benefit of the Parties named herein and their respective successors and permitted assigns.
