Appropriate adjustments to reflect such distribution shall be made to the number and/or class of Shares subject to this Agreement and to the price per share to be paid upon the exercise of the Repurchase Right in order to reflect the effect of any such Recapitalization upon the Corporation's capital structure. 4. ESCROW. 4.1 Deposit. Upon issuance, the certificates representing the Escrowed W&B Shares and the certificates representing the Escrowed Ocean Way Shares shall be deposited in escrow with the Secretary of the Corporation to be held in accordance with the provisions of this Section 4. Each deposited certificate shall be accompanied by a duly-executed Assignment Separate from Certificate in the form of Exhibit C. The deposited certificates, together with any other assets or securities from time to time deposited with the Secretary of the Corporation pursuant to the requirements of this Agreement, shall remain in escrow until such time or times as the certificates (or other assets and securities) are to be released or otherwise surrendered for cancellation in accordance with Section 4.3. Upon deposit of the certificates (or other assets and securities) in escrow by the Secretary of the Corporation, each of W&B and Ocean Way shall be issued a receipt acknowledging the number of Escrowed W&B Shares and Escrowed Ocean Way Shares (or other assets and securities) delivered in escrow. 4.2 Recapitalization/Reorganization. Any new, substituted or additional securities or other property which is by reason of any Recapitalization or reorganization distributed with respect to the Escrowed W&B Shares and/or the Escrowed Ocean Way Shares shall be immediately delivered to the Corporation to be held in escrow under this Section 4, but only to the extent the Escrowed W&B Shares and/or the Escrowed Ocean Way Shares, as the case may be, are at the time subject to the escrow requirements hereunder. However, all regular cash dividends on the Escrowed W&B Shares and Escrowed Ocean Way Shares (or other securities at the time held in escrow) shall be paid directly to W&B and Ocean Way, respectively, and shall not be held in escrow. 4.3 Release/Surrender. The Escrowed W&B Shares and Escrowed Ocean Way Shares, together with any other assets or securities held in escrow hereunder, shall be subject to the following terms relating to their release from escrow or their surrender to the Corporation for repurchase and cancellation: (a) Should the Corporation elect to exercise the Repurchase Right with respect to any of the Escrowed W&B Shares and/or the Escrowed Ocean Way Shares, then the escrowed certificates representing the Escrowed W&B Shares and/or Escrowed Ocean Way Shares, as the case may be, (together with any other assets or securities attributable thereto) shall be surrendered to the Corporation concurrently with the payment to W&B and/or Ocean Way, as the case may be, of an amount equal to $0.001 per share, and W&B and/or Ocean Way, as the case may be, shall cease to have any further rights or claims with respect to such shares (or other assets or securities attributable thereto). (b) Should the Corporation elect not to exercise the Repurchase Right or should the Corporation's Repurchase Right terminate pursuant to Paragraphs (a), (b) and (c) of Section 3.1, with respect to any Escrowed W&B Shares and/or the Escrowed Ocean Way Shares held at the time in escrow hereunder, then the escrowed certificates for those shares (together with any other assets or securities attributable thereto) shall be immediately released to W&B and/or Ocean Way, as the case may be. (c) All of the Escrowed W&B Shares and/or the Escrowed Ocean Way Shares (or other assets or securities) released from escrow shall nevertheless remain subject to the Lock-Up Agreement, until such restriction terminates. 5. SPECIAL TAX ELECTION. 5.1 Section 83(b) Election. Under Code Section 83, the excess of the fair market value of the Shares on the date any forfeiture restrictions applicable to such shares lapse over the price paid or value of services rendered for such shares will be reportable as ordinary income on the lapse date. For this purpose, the term "forfeiture restrictions" includes the right of the Corporation to repurchase the Shares pursuant to the Repurchase Right. Each of W&B and Ocean Way may elect under Code Section 83(b) to be taxed at the time the Shares are acquired, rather than when and as such Shares cease to be subject to such forfeiture restrictions. Such election must be filed with the Internal Revenue Service within thirty (30) days after the date of this Agreement. Even if the fair market value of the Shares on the date of this Agreement equals the price paid or value of services rendered (and thus no tax is payable), the election must be made to avoid adverse tax consequences in the future. THE FORM FOR MAKING THIS ELECTION IS ATTACHED AS EXHIBIT D HERETO. EACH OF W&B AND OCEAN WAY UNDERSTANDS THAT FAILURE TO MAKE THIS FILING WITHIN THE APPLICABLE THIRTY (30)-DAY PERIOD WILL RESULT IN THE RECOGNITION OF ORDINARY INCOME AS THE FORFEITURE RESTRICTIONS LAPSE. 5.2 FILING RESPONSIBILITY. EACH OF W&B AND OCEAN WAY ACKNOWLEDGES THAT IT IS ITS SOLE RESPONSIBILITY, AND NOT THE RESPONSIBILITY OF THE CORPORATION TO FILE A TIMELY ELECTION UNDER CODE SECTION 83(b), EVEN IF W&B AND/OR OCEAN WAY REQUESTS THE CORPORATION OR ITS REPRESENTATIVES TO MAKE THIS RULING ON ITS BEHALF. 6. GENERAL PROVISIONS 6.1 Assignment. The Corporation may assign the Repurchase Right to any person or entity selected by the Corporation's Board of Directors, including without limitation, one or more shareholder of the Corporation. 6.2 Notices. Any notice required to be given under this Agreement shall be in writing and shall be deemed effective upon personal delivery or upon deposit in the U.S. mail, registered or certified, postage prepaid and properly addressed to the party entitled to such notice at the address indicated below such party's signature line on this Agreement or at such other address as such party may designate by ten (10) days' advance written notice under this section to all other parties to this Agreement. 6.3 No Waiver. The failure of the Corporation in any instance to exercise the Repurchase Right shall not constitute a waiver of any other repurchase rights that may subsequently arise under the provisions of this Agreement or any other agreement between the Corporation, W&B and/or Ocean Way. No waiver of any breach or condition of this Agreement shall be deemed to be a waiver of any other or subsequent breach or condition, whether of like or different nature. 6.4 Cancellation of Shares. If the Corporation shall make available, at the time and place and in the amount and form provided in this Agreement, the consideration for the Shares to be purchased in accordance with the provisions of this Agreement, then from and after such time, the person from whom such shares are to be purchased shall no longer have any rights as a holder of such shares (other than the right to receive payment of such consideration in accordance with this Agreement). Such shares shall be deemed purchased in accordance with the applicable provisions hereof, and the Corporation shall be deemed the owner and holder of such shares, whether or not the certificate or certificates therefor have been delivered as required by this Agreement. 6.5 W&B and Ocean Way Undertaking. Each of W&B and Ocean Way hereby agrees to take whatever additional action and execute whatever additional documents the Corporation may deem necessary or advisable in order to carry out or effect one or more of the obligations or restrictions imposed on W&B, Ocean Way or the Shares pursuant to the provisions of this Agreement. 6.6 Governing Law.

This Agreement may be executed in one or more counterparts. Each such counterpart shall be deemed to be an original and all such counterparts shall together constitute one and the same instrument. 6.9 Captions.

The parties agree that actual attorneys' fees shall be based on the attorneys' fees actually incurred (based on the attorneys' customary hourly billing rates) rather than the court or arbitrator making an independent inquiry concerning reasonableness. 6.12 Remedies Cumulative. The remedies of each party contained in this Agreement are cumulative and shall not exclude or diminish any other remedies to which such party may be lawfully entitled. 6.13 Dispute Resolution. All claims, disputes and other matters in controversy ("Dispute") arising directly or indirectly out of or related to this Agreement, or the breach thereof, whether contractual or noncontractual, and whether during the term or after the termination of this Agreement, shall be resolved exclusively according to the procedures set forth in this Section.

The parties shall attempt in good faith to resolve the Dispute by mediation under the American Arbitration Association Commercial Mediation Rules in effect on the date of the Dispute Notice. If the parties cannot agree on the selection of a mediator within twenty (20) days after delivery of the Dispute Notice, the mediator shall be selected by the American Arbitration Association. If the Dispute has not been resolved by mediation within sixty (60) days after delivery of the Dispute Notice, then the Dispute shall be determined by arbitration in accordance with the provisions of paragraph (b) below. (b) Any Dispute that is not settled by mediation as provided in paragraph (a) above shall be resolved by arbitration before a single arbitrator appointed by the American Arbitration Association or its successor in Orange County. The determination of the arbitrator shall be final and absolute. The arbitrator shall be governed by the duly promulgated rules and regulations of the American Arbitration Association or its successor then in effect, and the pertinent provisions of the laws of the State of California relating to arbitration. The decision of the arbitrator may be entered as a final judgment in any court of the State of California or elsewhere.
