Not later than 90 days after the end of each of FY2006, the twelve-month period ended March 31, 2007, FY2007 and FY2008, Buyer shall prepare and shall deliver to Sellers an EBIT statement for such period setting forth Buyer’s calculation of the EBIT for such period. If Sellers choose, they may cause a single firm of independent accountants to audit Buyer’s calculation of the EBIT for such period (at Sellers’ sole cost and expense, provided, that if Buyer’s calculation of the EBIT for such period is different by more than 10% from the EBIT for such period as ultimately agreed by Buyer and Sellers or as ultimately determined by the Independent Auditor in accordance with this Section 2.2(b), then Sellers shall submit an invoice to Buyer for the costs of such audit and Buyer shall reimburse Sellers for such reasonable costs up to a maximum of $30,000, promptly after receipt of such invoice), and Sellers will deliver to Buyer not later than 30 days after receipt of Buyer’s EBIT statement a detailed written statement describing their objections (if any) to Buyer’s determination of the EBIT for such period and setting forth their calculation of the EBIT for such period. If Sellers do not so object, Buyer’s determination of the EBIT for such period will be conclusive and binding upon Buyer and Sellers. Buyer and Sellers will use their respective commercially reasonable efforts to resolve any such disputes, but if a final resolution is not obtained within 30 days after Sellers have submitted their objections, any remaining disputes will be resolved by an accounting firm mutually agreeable to Buyer and Sellers (the “Independent Auditor”). If Buyer and Sellers are unable to mutually agree on the Independent Auditor, the Independent Auditor will be selected by lot from a list of four nationally or regionally recognized firms after eliminating one firm designated as objectionable by each of Buyer and Sellers. The Independent Auditor shall make its determination based exclusively on presentations and supporting material provided by Buyer and Sellers and not pursuant to any independent review. The EBIT for such period as determined by the Independent Auditor shall be in an amount between Buyer’s and Sellers’ determinations of the EBIT for such period, respectively. The determination of the Independent Auditor will be conclusive and binding upon Buyer and Sellers. The fees and expenses of the Independent Auditor shall be shared equally by Buyer and Sellers. The purpose of this Section 2.2(b) is to determine the Purchase Price to be paid by Buyer to Sellers under this Agreement. Accordingly, any adjustment pursuant to this Section 2.2(b) shall not be deemed to be an indemnification by Sellers pursuant to

Section 10, nor preclude Buyer from exercising any indemnification rights pursuant to Section 10.

(i) On or before the last day of the first full month after the Closing Date, Buyer shall prepare and shall deliver to Sellers a statement setting forth the Working Capital (such statement, the “Working Capital Statement”) calculated in a manner consistent with Schedule 2.2(c); provided, that the parties hereby agree that for purposes of preparing the Working Capital Statement, current assets shall exclude any additional reserve for slow moving inventory that is required by Buyer in excess of the $52,000 reserve that is already set forth on the Balance Sheet. Any inventory value (inventory plus pre-paid inventory, but excluding any and all inventory valuation reserves) in excess of $850,000 shall be specifically excluded from the calculation of Working Capital. In the event that the Closing Date does not occur at a financial week or month end for accounting purposes, the parties shall agree on mutually acceptable roll forward or roll back procedures. The parties shall cooperate with each other in connection with, shall furnish to each other all such information as may be reasonably requested by a party, and shall provide the other parties and their representatives reasonable access to books and records and relevant personnel during the preparation of the Working Capital Statement and during the resolution of any disputes that may arise under this Section 2.2(c).

(ii) If Sellers disagree with the determination of the Working Capital as shown on the Working Capital Statement, Sellers shall notify Buyer in writing of such disagreement within 30 calendar days after delivery of the Working Capital Statement, which notice shall describe the nature of any such disagreement in reasonable detail, identify the specific items involved and the dollar amount of each such disagreement and provide reasonable supporting documentation for each such disagreement. After the end of such 30 calendar day period, neither Buyer nor Sellers may introduce additional disagreements with respect to any item in the Working Capital Statement or increase the amount of any disagreement, and any item not so identified shall be deemed to be agreed to by Buyer and Sellers and will be final and binding upon Buyer and Sellers. During the 30 calendar day period of its review, Sellers shall have access to any documents, schedules or workpapers used in the preparation of the Working Capital Statement.

(iii) Buyer and Sellers agree to negotiate in good faith to resolve any disagreement properly identified by Sellers to Buyer pursuant to Section 2.2(c)(ii). If Buyer and Sellers are unable to resolve all such disagreements within 30 calendar days after delivery to Sellers of written notice of such disagreement, then such disagreements shall be submitted for

final and binding resolution to an independent auditor selected in accordance with the procedures set forth in Section 2.2(b) for the selection of the Independent Auditor (the “Accounting Arbitrator”) to resolve such disagreements. The Accounting Arbitrator will only consider those items and amounts set forth in the Working Capital Statement as to which Buyer and Sellers have disagreed within the time periods and on the terms specified above and must resolve the matter in accordance with the terms and provisions of this Agreement. The Accounting Arbitrator shall deliver to Buyer and Sellers, as promptly as practicable and in any event within 90 calendar days after its appointment, a written report setting forth the resolution of any such disagreement determined in accordance with the terms of this Agreement. The Accounting Arbitrator shall select as a resolution the position of either Buyer or Sellers for each item of disagreement and may not impose an alternative resolution. The Accounting Arbitrator shall make its determination based exclusively on presentations and supporting material provided by Buyer and Sellers and not pursuant to any independent review. The determination of the Accounting Arbitrator shall be final and binding upon Buyer and Sellers. The fees, expenses and costs of the Accounting Arbitrator shall be shared equally by Sellers, on the one hand, and Buyer, on the other hand. Other than such fees and expenses of the Accounting Arbitrator, Buyer and Sellers shall each be responsible for their own costs and expenses incurred in connection with any actions taken pursuant to this Section 2.2(c).

(iv) The parties hereto agree that the Working Capital Statement will not include any changes in assets or liabilities as a result of purchase accounting adjustments arising from or resulting as a consequence of the transactions contemplated hereby.

(v) If the Working Capital as finally determined in accordance with this Section 2.2(c) is less than the Target Working Capital, the Purchase Price shall be decreased on a dollar-for-dollar basis by the amount of such shortfall, and if the Working Capital is greater than the Target Working Capital, the Purchase Price shall be increased on a dollar-for-dollar basis by the amount of such excess.

(vi) If any adjustment under this Section 2.2(c) results in a reduction in the Purchase Price, Sellers shall pay to Buyer the amount of such reduction, and if any adjustment results in an increase in the Purchase Price, Buyer shall pay to Sellers the amount of such increase, in each case, by wire transfer of immediately available funds to an account designated by the party or parties receiving payment within five Business Days after the final determination of the amount of such reduction or increase in Purchase Price in accordance with this Section 2.2(c); provided, that if any amount is required to be paid to Sellers in accordance with this Section 2.2(c), such amount shall be paid to them in accordance with their Pro Rata Shares but shall be subject to Buyer’s right of set—off in accordance with Section 10.7;

provided, further, that if any amount is required to be paid to Buyer in accordance with this Section 2.2(c), then such amount shall, at the sole election of Buyer, be paid from the Escrow Amount to the extent that it is less than $250,000, and Buyer and Sellers shall promptly submit joint written instructions to the Escrow Agent pursuant to the Escrow Agreement directing the Escrow Agent to release such amount to Buyer (with the portion, if any, of such amount in excess of $250,000 to be paid by Sellers by wire transfer, with Sellers being jointly and severally liable to Buyer for such amount), but if Buyer does not elect to so set off such amount, both Sellers shall be jointly and severally liable to Buyer for such amount.

(vii) The purpose of this Section 2.2(c) is to determine the Purchase Price to be paid by Buyer to Sellers under this Agreement. Accordingly, any adjustment pursuant to this Section 2.2(c) shall not be deemed to be an indemnification by Sellers pursuant to Section 10, nor preclude Buyer from exercising any indemnification rights pursuant to Section 10.

Purchase Price shall be allocated to the assets of the Company for Tax purposes in a manner consistent with Schedule 6.3(c). Except as Buyer and Sellers may otherwise agree or as may be required otherwise pursuant to a final determination within the meaning of Section 1313(a) of the IRC, the agreements regarding fair market values and allocation set forth on Schedule 6.3(c) shall be binding on Sellers and Buyer for all Tax reporting purposes. The allocation of the Tax Purchase Price pursuant to this Section 6.3(c), as it may be modified by any agreement of Buyer and Sellers or any final determination within the meaning of Section 1313(a) of the IRC or corresponding provision of state, local or foreign income Tax law, is referred to herein as the “Allocation.”

(d) Notwithstanding anything herein to the contrary, Buyer shall pay or cause the Company to pay any Taxes imposed on the Company by reason of the 338(h)(10) Election, and any such Taxes shall not be taken into account in the calculation of Working Capital.

(e) Notwithstanding anything herein to the contrary, as part of the Tax Purchase Price, Buyer shall pay or cause to be paid to Sellers, in cash, the amounts (such amounts, the “Tax Adjustment”) necessary to cause each Seller’s after-Tax net proceeds from Purchase Price for the Shares, taking into account the 338(h)(10) Election, to be equal to the after-Tax net proceeds that such Seller would have received had the 338(h)(10) Election not been made and no amount had been allocated to the covenants set forth in the Noncompetition Agreements of this Agreement or any similar undertaking of either Seller, taking into account all appropriate federal, state, local and foreign Tax implications arising from the transactions contemplated by this Agreement, including any Taxes imposed on the Tax Adjustment; provided, however, the Tax Adjustment shall in no event be a negative number (that is, in no event shall either Seller be required to make a Tax Adjustment payment to Buyer or the Company, even if making a 338(h)(10) Election is more favorable to either Seller). Sellers shall cooperate with Buyer and the Company in good faith to minimize the amount of the Tax Adjustment; provided that Seller shall not be required to incur material risk, liability or expense to minimize the amount of the Tax Adjustment.

(f)

(i) In calculating the Tax Adjustment, (A) only the items of income, gain, deduction, loss and expense arising out of the transactions contemplated by this Agreement shall be considered (including without limitation any recognition of income, gain, deduction or loss or change in character thereof as a result of the transactions contemplated by this Agreement and the 338(h)(10) Election), (B) Sellers shall be treated as subject to the maximum combined federal and state marginal income tax rates (without netting for any federal benefit of deducting state or local income Tax) applicable to an individual residing in the State of Florida, and (C) notwithstanding any actual receipt thereof after the taxable year when Closing occurs, Sellers shall be deemed to have received during the taxable year when Closing occurs both the Tax Adjustment and the entire,

maximum amount of the Tax Purchase Price (including without limitation the face amounts of such Seller’s Promissory Note, their Buyer Earn-Out Shares, and their Pro Rata Shares of the Earn-Out Amounts (as if each were guaranteed) and the Escrow Amount).

(ii) Within 30 days after the final determination of Working Capital in accordance with Section 2.2(c), Buyer shall provide to Sellers a schedule, with supporting workpapers, setting forth a calculation of the Tax Adjustment (the “Tax Adjustment Schedule”). During the 20 days following the receipt by Sellers of the Tax Adjustment Schedule, Buyer and Sellers shall meet and confer and attempt in good faith to agree upon and finalize the Tax Adjustment Schedule. Within 30 days after receipt of such Tax Adjustment Schedule, Sellers shall notify the Buyer whether Sellers concur or disagree with such Tax Adjustment Schedule and, if applicable, the disagreements. If such disagreements cannot be resolved between Buyer and Sellers within 10 days after delivery of notice by Sellers to Buyer, the disagreements shall then be referred to the Accounting Arbitrator for resolution in accordance with the procedures set forth in Section 2.2(c); provided, that the Accounting Arbitrator’s determination shall be limited to choosing the position either of Buyer or Sellers and the fees of the Accountant shall be borne by Sellers, on the one hand, and Buyer on the other hand, in such amount(s) as shall be determined by the Accounting Arbitrator based on the proportion that the aggregate amount of disputed items submitted to the Accounting Arbitrator that is unsuccessfully disputed by Sellers, on the one hand, or Buyer on the other hand, as determined by the Accounting Arbitrator, bears to the total amount of such disputed items so referred to the Accounting Arbitrator for resolution.

(iii) On or before April 10, 2007 Buyer shall pay the Tax Adjustment as calculated as of such time. If a disagreement regarding the amount of the Tax Adjustment is pending at that time, Buyer shall pay the undisputed portion thereof on or before April 10, 2007 and shall pay any excess of the Tax Adjustment as then calculated by the Buyer to the Escrow Agent with the irrevocable instruction that such excess be disbursed pursuant to either the agreement of Buyer and Sellers or, absent such agreement, pursuant to the award of the Accounting Arbitrator.

(iv) The obligations of Buyer to pay the Tax Adjustment shall survive until the expiration of all statutes of limitation with respect to Tax Returns of Sellers and the Company for the taxable years ending on or including the Closing Date and each succeeding taxable year until no portion of the Tax Purchase Price remains to be paid, to the extent necessary to increase the amount of the Tax Adjustment to reflect any final determination (as defined in Section 1313(a) of the IRC or comparable provisions of other Tax laws) that would increase or decrease the amount of the Tax Adjustment had such final determination had been taken into

account previously in the calculation of the Tax Adjustment. The amount of any such increase shall be determined by the preparation of a revised Tax Adjustment Schedule that takes into account such final determination, pursuant to the procedures set forth in Section 1.12(c)(2) of the IRC (commencing with the date of notice of such final determination in lieu of the date the Closing Net Working Capital is determined), and Buyer shall pay any such increase in the Tax Adjustment within five Business Days after the amount of any such increase is determined in accordance with such procedures. Buyer shall promptly provide written notice to Sellers of any audit or other investigation that may be initiated in connection with the 338(h)(10) Election or that may affect the amount of the Tax Adjustment.

financial condition of Buyer or the Company for taxable periods after the Closing Date, there shall be no settlement or closing or other agreement with respect thereto without the prior written consent of Buyer or the Company, which consent will not be unreasonably withheld.

(g) Sellers and Buyer agree, upon request, to use their commercially reasonable best efforts, and to use their commercially reasonable best efforts to cause the Company to obtain any certificate or other document from any Governmental Body 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 by this Agreement).

if any, attributable to a Straddle Period shall be allocated (i) to Sellers for the period up to and including the close of business on the Closing Date, and (ii) to Buyer for the period subsequent to the Closing Date.

(j) Sellers shall be jointly and severally, as to all Taxes of the Company (except with respect to, and to the extent of, Taxes for which a liability is accrued and reserved for in the Closing Balance Sheet and taken into account in the calculation of Closing Working Capital), responsible for and shall indemnify and hold harmless Buyer and the Company from and against the following: (i) any and all Taxes of the Company with respect to all Taxable periods of the Company ending on or prior to the Closing Date, and the portion of any Straddle Period ending on the Closing Date (allocated to Sellers pursuant to Section 6.4(i)); (ii) any and all Taxes resulting from any breach of the representations and warranties contained in Section 3.11 hereof; (iii) any and all Taxes imposed on the Company solely by a reason of being or having been a member of (or a predecessor thereof) an affiliated, consolidated, combined or unitary group on or prior to the Closing Date, pursuant to Treasury Regulations § 1.1502-6(a) (or any predecessor or successor thereof or any analogous or similar provision under state, local or foreign Legal Requirement), or otherwise; and (iv) any out-of-pocket costs or expenses (including reasonable legal and accounting fees) incurred in connection with a claim in respect of any of the foregoing.

Upon notice to Sellers specifying in reasonable detail the basis for such set-off, Buyer may set off any amount to which it may be entitled under Section 6.4 or this Section 10 or otherwise under this Agreement or any Buyer Closing Document or Sellers’ Closing Document against the Escrow Amount (provided, that recourse to the Escrow Amount shall be in accordance with the terms of, and subject to the conditions of, the Escrow Agreement). The exercise of such right of set-off by Buyer in good faith, whether or not ultimately determined to be justified, will not constitute an event of default under the Promissory Notes, any instrument securing a Promissory Note, this Agreement or any other Buyer Closing Document or Sellers’ Closing Document. Neither the exercise of nor the failure to exercise such right of set-off will constitute an election of remedies or limit Buyer in any manner in the enforcement of any other remedies that may be available to it.

10.8 PROCEDURE FOR INDEMNIFICATION — THIRD PARTY CLAIMS. Promptly after receipt by an indemnified party under Section 10.2 or 10.3 of notice of the commencement of any Proceeding against it, such indemnified party will, if a claim is to be made against an indemnifying party under such Section, give notice to the indemnifying party of the commencement of such claim, but the failure to notify the indemnifying party will not relieve the indemnifying party of any liability that it may have to any indemnified party, except to the extent that the indemnifying party demonstrates that the defense of such action is prejudiced by the indemnified party’s failure to give such notice, and then only to the extent of such prejudice.

(a) If any Proceeding referred to in Section 10.8(a) is brought against an indemnified party and it gives notice to the indemnifying party of the commencement of such Proceeding, the indemnifying party will, unless the claim involves Taxes, be entitled to participate in such Proceeding and, to the extent that it wishes (unless (i) the indemnifying party is also a party to such Proceeding and the indemnified party determines in good faith that joint representation would be inappropriate, (ii) the indemnifying party fails to provide reasonable assurance to the indemnified party of its financial capacity to defend such Proceeding and provide indemnification with respect to

such Proceeding), or (iii) the indemnifying party fails to provide notice of its election to assume the defense of such Proceeding in accordance with the last sentence of this Section 10.8(b), to assume the defense of such Proceeding with counsel satisfactory to the indemnified party and, after notice from the indemnifying party to the indemnified party of its election to assume the defense of such Proceeding, the indemnifying party will not, as long as it diligently conducts such defense, be liable to the indemnified party under this Section 10 for any fees of other counsel or any other expenses with respect to the defense of such Proceeding, in each case subsequently incurred by the indemnified party in connection with the defense of such Proceeding, other than reasonable costs of investigation. If the indemnifying party assumes the defense of a Proceeding, (i) it will be conclusively established for purposes of this Agreement that the claims made in that Proceeding are within the scope of and subject to indemnification; (ii) no compromise or settlement of such claims may be effected by the indemnifying party without the indemnified party’s consent unless (A) there is no finding or admission of any violation of Legal Requirements or any violation of the rights of any Person and no effect on any other claims that may be made against the indemnified party, and (B) the sole relief provided is monetary damages that are paid in full by the indemnifying party; and (iii) the indemnified party will have no Liability with respect to any compromise or settlement of such claims effected without its consent. If notice is given to an indemnifying party of the commencement of any Proceeding and the indemnifying party does not, within ten (10) calendar days after the indemnified party’s notice is given, give notice to the indemnified party of its election to assume the defense of such Proceeding, the indemnifying party will be bound by any determination made in such Proceeding or any compromise or settlement effected by the indemnified party.

(b) Notwithstanding the foregoing, if an indemnified party determines in good faith that there is a reasonable probability that a Proceeding may adversely affect it or its Related Persons other than as a result of monetary damages for which it would be entitled to indemnification under this Agreement, the indemnified party may, by notice to the indemnifying party, assume the exclusive right to defend, compromise, or settle such Proceeding, but the indemnifying party will not be bound by any determination of a Proceeding so defended or any compromise or settlement effected without its consent (which may not be unreasonably withheld).

(c) Sellers hereby consent to the non-exclusive jurisdiction of any court in which a Proceeding is brought against any Indemnified Person for purposes of any claim that an Indemnified Person may have under this Agreement with respect to such Proceeding or the matters alleged therein, and agree that process may be served on Sellers with respect to such a claim anywhere in the world.

10.9 PROCEDURE FOR INDEMNIFICATION — OTHER CLAIMS. A claim for indemnification for any matter not involving a third-Person claim may be asserted by notice to the party from whom indemnification is sought.

10.10 FINAL DETERMINATION. After the giving of any claim for indemnification pursuant to this Section 10, the amount of indemnification to which an indemnified party shall be entitled under this Section 10 shall be determined: (a) by the written

agreement between the indemnified party and the indemnifying party; (b) by a final judgment or decree of any court of competent jurisdiction; (c) pursuant to Section 11.16; or (d) by any other means to which the indemnified party and the indemnifying party shall agree in writing. The judgment or decree of a court shall be deemed final when the time for appeal, if any, shall have expired and no appeal shall have been taken or when all appeals taken shall have been finally determined. All amounts due to the indemnified party as so finally determined shall be paid by wire transfer within three Business Days after such final determination, together with interest thereon from the date of the receipt of notice of an indemnification claim by the indemnified party to the indemnifying party, at the rate of six percent (6%) per annum.

11.5 JURISDICTION; SERVICE OF PROCESS. Any action or proceeding seeking to enforce any provision of, or based on any right arising out of, this Agreement may be brought against any of the parties in the courts of the State of California, County of Los Angeles, or, if it has or can acquire jurisdiction, in the United States District Court for the Central District of California, Western Division, and each of the parties consents to the jurisdiction of such courts (and of the appropriate appellate courts) in any such action or proceeding and waives any objection to venue laid therein. Process in any action or proceeding referred to in the preceding sentence may be served on any party anywhere in the world.

11.6 FURTHER ASSURANCES. The parties agree (a) to furnish upon request to each other such further information, (b) to execute and deliver to each other such other documents, and (c) to do such other acts and things, all as the other party may reasonably request for the purpose of carrying out the intent of this Agreement and the documents referred to in this Agreement.

11.7 WAIVER. The rights and remedies of the parties to this Agreement are cumulative and not alternative. Neither the failure nor any delay by any party in exercising any right, power, or privilege under this Agreement or the documents referred to in this Agreement will operate as a waiver of such right, power, or privilege, and no single or partial exercise of any such right, power, or privilege will preclude any other or further exercise of such right, power, or privilege or the exercise of any other right, power, or privilege. To the maximum extent permitted by applicable law, (a) no claim or right arising out of this Agreement or the documents referred to in this Agreement can be discharged by one party, in whole or in part, by a waiver or

renunciation of the claim or right unless in writing signed by the other party; (b) no waiver that may be given by a party will be applicable except in the specific instance for which it is given; and (c) no notice to or demand on one party will be deemed to be a waiver of any obligation of such party or of the right of the party giving such notice or demand to take further action without notice or demand as provided in this Agreement or the documents referred to in this Agreement.

11.8 ENTIRE AGREEMENT AND MODIFICATION. This Agreement supersedes all prior agreements between the parties with respect to its subject matter other than the Confidentiality Agreement but specifically including the Letter of Intent and constitutes (along with the documents referred to in this Agreement) a complete and exclusive statement of the terms of the agreement between the parties with respect to its subject matter. This Agreement may not be amended except by a written agreement executed by the party to be charged with the amendment.

11.9 DISCLOSURE LETTER. The disclosures in the Disclosure Letter, and those in any Supplement thereto, must relate only to the representations and warranties in the Section of the Agreement to which they expressly relate and not to any other representation or warranty in this Agreement. In the event of any inconsistency between the statements in the body of this Agreement and those in the Disclosure Letter (other than an exception expressly set forth as such in the Disclosure Letter with respect to a specifically identified representation or warranty), the statements in the body of this Agreement will control.

11.10 ASSIGNMENTS, SUCCESSORS, AND NO THIRD-PARTY RIGHTS. Neither party may assign any of its rights under this Agreement without the prior consent of the other parties except that Buyer may assign any of its rights under this Agreement to any Subsidiary of Buyer. Subject to the preceding sentence, this Agreement will apply to, be binding in all respects upon, and inure to the benefit of the successors and permitted assigns of the parties. Nothing expressed or referred to in this Agreement will be construed to give any Person other than the parties to this Agreement any legal or equitable right, remedy, or claim under or with respect to this Agreement or any provision of this Agreement. This Agreement and all of its provisions and conditions are for the sole and exclusive benefit of the parties to this Agreement and their successors and assigns.

11.11 SEVERABILITY. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement will remain in full force and effect. Any provision of this Agreement held invalid or unenforceable only in part or degree will remain in full force and effect to the extent not held invalid or unenforceable.

11.12 SECTION HEADINGS, CONSTRUCTION. The headings of Sections in this Agreement are provided for convenience only and will not affect its construction or interpretation. All references to “Section” or “Sections” refer to the corresponding Section or Sections of this Agreement. All words used in this Agreement will be construed to be of such gender or number as the circumstances require. Unless otherwise expressly provided, the word “including” does not limit the preceding words or terms.

11.13 TIME OF ESSENCE. With regard to all dates and time periods set forth or referred to in this Agreement, time is of the essence.

11.14 GOVERNING LAW. This Agreement will be governed by the Legal Requirements of the State of California without regard to conflicts of laws principles.

11.15 COUNTERPARTS; FACSIMILE. This Agreement may be executed in one or more counterparts and via facsimile, each of which will be deemed to be an original copy of this Agreement and all of which, when taken together, will be deemed to constitute one and the same agreement.

11.16 ARBITRATION.

(a) All disputes (other than disputes governed by Sections 2.2(b), 2.2(c) and 6.3 of this Agreement) arising under this Agreement or any other document referenced in this Agreement (other than the Noncompetition Agreements and the Releases) shall be settled by binding arbitration; provided, however, that this Section 11.16 shall not preclude any party from seeking injunctive relief in a court of competent jurisdiction. Arbitration shall be held in Los Angeles, California under the auspices of the American Arbitration Association (the “AAA”) pursuant to the Commercial Arbitration Rules of the AAA, and shall be by one arbitrator, independent of the parties to this Agreement, selected from a list provided by the AAA in accordance with such Commercial Arbitration Rules. The arbitrator shall make his or her decision in writing at the earliest convenient date. To the maximum extent permitted by law, the decision of the arbitrator shall be final and binding on the parties to this Agreement and not be subject to appeal. If a party against whom the arbitrator renders an award fails to abide by such award, the other parties may bring an action to enforce the same in a court of competent jurisdiction. The fees and expenses of the arbitration (including reasonable attorneys’ fees) or any action to enforce an arbitration award shall be paid by the party that does not prevail in such arbitration.

(b) The parties agree that all facts and information relating to any arbitration arising under this Agreement shall be kept confidential to the extent possible. The parties agree that all documents filed with any court in connection with the resolution of any dispute hereunder shall be filed under seal to the extent possible. The parties further agree and acknowledge that a claim for damages for breach of the agreement to maintain confidentiality shall not provide an adequate remedy and acknowledge that a claim for specific performance or injunctive relief is appropriate.

(c) The parties shall have the right to enforce this Section 11.16 in a court of competent jurisdiction. The parties waive, for themselves and for any Person acting on behalf of or otherwise claiming through them, any right they may otherwise have to resolve claims by a court or by a jury, except as necessary to enforce an award rendered in arbitration, to enforce this Section 11.16 and to seek injunctive or other equitable relief.
