    RECITALS

    

    WHEREAS,
      the Board of Directors of the Company has established the 2006 Stock Option
      Deferred Stock and Restricted Stock Plan (the "Plan" unless otherwise specified)
      effective as of ____________; and

    

    WHEREAS,
      pursuant to the provisions of said Plan, the Board of Directors of the Company,
      by action duly taken on _________________, sold to the Stock Purchaser shares
      of
      the Common Stock of the Company (the "Common Stock") on the terms and conditions

    AGREEMENT

    

    NOW,
      THEREFORE, in consideration of the foregoing and of the mutual covenants set
      forth herein and other good and valuable consideration, the parties hereto
      agree
      as follows:

    

    1.
      Price.
      The
      Stock Purchaser hereby purchases an aggregate of ___________ shares of Common
      Stock at the price of $____________ per share (the "Price"), on the terms and
      conditions set forth herein. Upon execution hereof, the Stock Purchaser shall
      pay to the Company the Price per share for the shares purchased hereby.
      [OPTIONAL PROVISION] The purchase price for the shares consist of the rendition
      of the following services _____________________. [OPTIONAL PROVISION] Pursuant
      to a determination of the Company's Board of Directors to provide financial
      assistance to the Stock Purchaser for the purchase of the shares the Stock
      Purchaser hereby by executing this Stock Purchase Agreement also executes the
      following promissory note:

     

    
      
         

      

      
        1

        
          

        

      

      
         

      

    

    
 

    [OPTIONAL
      PROVISION] Promissory
      Note.
      On or
      before ______________ (the "Due Date") the Stock Purchaser promises to pay
      the
      sum of _________________ with interest at the rate of 9% per annum to accrue
      and
      to be paid along with principal on the Due Date, subject, however, to an
      acceleration of the Due Date in the event that the Company should be sold in
      which case the Due Date shall be the date of the closing of such sale. This
      note
      is secured by _______________ shares of Common Stock purchased by the Stock
      Purchaser pursuant hereto. The Stock Purchaser hereby grants the Company a
      security interest in the shares of Common Stock purchased hereby. The secured
      party shall have such rights of a secured party as are provided under the
      California Commercial Code. To effectuate this pledge, the shares of Common
      Stock serving as collateral shall be delivered to a pledgeholder who shall
      be
      the Secretary of the Company who agrees to hold the stock as pledgeholder under
      this Agreement. Until the promissory note is paid in full the Stock Purchaser
      grants an irrevocable proxy, coupled with an interest to secure payment of
      this
      note to ________________________ to vote his shares on all matters that come
      up
      for a shareholders' vote as ______________________ may determine. This note
      is
      non-recourse meaning that in the event of non-payment of the principal and
      interest on the Due Date, the sole recourse of the Company shall be against
      the
      collateral and the Stock Purchaser shall have no personal liability with respect
      to the note. The Stock Purchaser hereby grants an irrevocable power of attorney
      to _______________________ to act as his attorney-in-fact to effectuate the
      transfer of shares in the event that recourse against the collateral becomes
      necessary. If and when the note is paid in full the shares shall be released
      from the pledge and the stock certificates representing the shares shall be
      delivered to the Stock Purchaser free of the pledge. The Stock Purchaser
      recognizes that a legend will be placed upon the stock certificates setting
      forth a reference to provisions hereof. 

    

    2.

      The
      shares set forth in the table below shall vest in installments of 20% per year
      for each year from the date hereof (or prior hereto as allowed by the Plan),
      as

      vesting dates set forth in the above table, the Company shall have no right

      Governing
      Plan.
      This
      Agreement hereby incorporates by reference the Plan and all of the terms and
      conditions of the Plan as heretofore amended and as the same may be amended
      from
      time to time hereafter in accordance with the terms thereof, but no such
      subsequent amendment shall adversely affect the Stock Purchaser's rights under
      this Agreement and the Plan except as may be required by applicable law. The
      Stock Purchaser expressly acknowledges and agrees that the pro-visions of this
      Agreement are subject to the Plan; the terms of this Agreement shall in no
      manner limit or modify the controlling provisions of the Plan, and in case
      of
      any conflict between the provisions of the Plan and this Agree-ment, the
      provisions of the Plan shall be con-trolling and binding upon the parties
      hereto. The Stock Purchaser also hereby expressly acknowledges, represents
      and
      agrees as follows:

    (a)
      Acknowledges receipt of a copy of the Plan, a copy of which is attached hereto
      and by reference incorporated herein, and represents that he is familiar with
      the terms and provisions of said Plan, and hereby accepts this Agreement Subject
      to all the terms and provisions of said Plan.

    

    (b)
      Agrees to accept as binding, conclusive and final all decisions or
      interpretations of the Board of Directors (or the Committee, if so authorized)
      upon any questions arising under the Plan.

    

    (c)
      Acknowledges that he is familiar with all Sections of the Plan including the
      provisions regarding Termina-tion of Employment.

    

    (d)
      Acknowledges, understands and agrees that the existence of the Plan and the
      execution of this Agreement are not sufficient by themselves to cause any
      purchase of stock under Plan to qualify for favorable tax
      treatment.

    

    4.
      Representations
      and Warranties.
      The
      Stock Pur-chaser hereby makes a representation and warranty that the shares
      are
      being acquired only for investment and without any present intention to sell
      or
      distribute such shares. An appropriate legend restricting transferability of
      the
      shares, as may be required by the Securities Act of 1933, may be placed by
      the
      Company on the certificates representing the shares, unless the shares are
      registered under Form S-8.

    

    5.
      Shares/Transferable.
      Until
      the shares are fully paid for or fully vested they may not be sold, pledged,
      hypothecated, assigned, encumbered, gifted or otherwise transferred in any
      manner, either voluntarily or involuntarily by operation of law, except by
      will
      or the laws of descent or distribution and except for the pledge created
      hereby.

    

    6.
      No
      Enlargement of Employee Rights.
      Nothing
      in this Agreement shall be construed to confer upon the Stock Purchaser (if
      an
      employee) any right to continued employment with the Company (or an Affiliated
      Company), or to restrict in any way the right of the Company (or an Affiliated
      Company if he is an employee thereof) to terminate his employment. Stock
      Purchaser acknowledges that in the absence of an express written employment
      agreement to the contrary, Stock Purchaser's employment with the Company may
      be
      terminated by the Company at any time, with or without cause.

    

    7.
      Withholding
      of Taxes.
      Stock
      Purchaser authorizes the Company to withhold, in accordance with any applicable
      law, from any compensation payable to him any taxes required to be withheld
      by
      federal, provincial or local law as a result of the issuance of stock pursuant
      to this Agreement. The Stock Purchaser acknowledges that it his own
      responsibility to file an 83(b) election with the Internal Revenue Service
      (if
      he is a U.S. resident) concerning this transaction or such other forms as may
      be
      applicable in his home jurisdiction. The Stock Purchaser shall contact his
      own
      personal accountant and provide the necessary information to the Stock
      Purchaser's accountant to permit the accountant to fill out and file on his
      behalf an 83(b) election form (if applicable or such other form as is required)
      which must be filed within 30 days from the date hereof. Failure to file such
      form timely may result in adverse tax consequences to the Stock Purchaser.
      Stock
      Purchaser acknowledges that it is not the Company's responsibility to provide
      him with tax advise or assistance, financial or otherwise in connection with
      the
      preparation, filling out and filing of the 83(b) election or any other election
      under his home jurisdiction.

      California.

    

    9.
      Agreement
      Binding on Successors.
      The
      terms of this Agreement shall be binding upon the executors, administrators,
      heirs, successors, transferees and assignees of the Stock
      Purchaser.

    

    10.
      Necessary
      Acts.
      The
      Stock Purchaser agrees to perform all acts and execute and deliver any documents
      that may be reasonably necessary to carry out the provisions of this Agreement,
      including but not limited to all acts and documents related to compliance with
      federal and/or state securities laws.

    

    11.
      Counterparts.
      For
      convenience this Agreement may be executed in any number of identical
      counterparts, each of which shall be deemed a complete original in itself and
      may be introduced in evidence or used for any other purpose without the
      production of any other counterparts.

    

    12.
      Invalid
      Provisions.
      In the
      event that any provision of this Agreement is found to be invalid or otherwise
      unenforceable under any applicable law, such invalidity or unenforceability
      shall not be construed as rendering any other provisions contained herein
      invalid or unenforceable, and all such other provisions shall be given full
      force and effect to the same extent as though the invalid and unenforce-able
      provision was not contained herein.

      Optionee further understands that the Option(s) granted hereunder shall expire
      and become un-exercisable as provided in Section 5(c) below.

     

       
    4.  Method
      of Exercise.
      This
      Option shall be deemed exercised as to the shares to be purchased when written
      notice of such exercise has been given to the Company at its principal business
      office by the Optionee with respect to the Common Stock to be purchased. Such
      notice shall be accompanied by full payment in cash or cash equivalents as
      determined by the Administrator. As determined by the Administrator, in its
      sole
      discretion, payment in whole or part may also be made (i) by cancellation of
      any
      indebtedness owed by the Company to the Optionee, (ii) by a full recourse
      promissory note executed by the Optionee, (iii) in the form of unrestricted
      Stock owned by the Optionee, or, in the case of the exercise of a Non-Qualified
      Stock Option, Restricted Stock or Performance Shares subject to an award under
      the Plan (based, in each case, on the Fair Market Value of the Stock on the
      date
      the option is exercised); provided, however, that in the case of an Incentive
      Stock Option, the right to make payment in the form of already owned shares
      may
      be authorized only at the time of grant, or (iv) by any combination of the
      foregoing or as set forth in the Plan. Any payment in the form of Stock already
      owned by the Optionee may be effected by use of an attestation form approved
      by
      the Administrator. If payment of the option exercise price of a NQSO is made
      in
      whole or in part in the form of Restricted Stock or Performance Shares, the
      shares received upon the exercise of such Option (to the extent of the number
      of
      shares of Restricted Stock or Performance Shares surrendered upon exercise
      of
      such Option) shall be restricted in accordance with the original terms of the
      Restricted Stock or Performance Share award in question, except that the
      Administrator may direct that such restrictions shall apply only to that number
      of shares surrendered upon the exercise of such Option.

     

           
      5.  Governing
      Plan.
      This
      Agreement hereby incorporates by reference the Plan and all of the terms and
      conditions of the Plan as heretofore amended and as the same may be amended

      time to time hereafter in accordance with the terms thereof, but no such
      subsequent amendment shall adversely affect the Optionee's rights under this
      Agreement and the Plan except as may be required by applicable law. The Optionee
      expressly acknowledges and agrees that the provisions of this Agreement are
      subject to the Plan; the terms of this Agreement shall in no manner limit or
      modify the controlling provisions of the Plan, and in case of any conflict
      between the provisions of the Plan and this Agreement, the provisions of the
      Plan shall be controlling and binding upon the parties hereto. The Optionee
      also
      hereby expressly acknowledges, represents and agrees as follows:

      accept as binding, conclusive and final all decisions or interpretations of

      Subsection 5(h) of the Plan; or (iii) the date that is six months following
      the
      Optionee's termination of employment, by reason of his/her death, or the date
      that is six months following his/her termination of employment, by reason of
      disability, whichever is applicable, as provided in Subsection 5(g) of the
      Plan

    

    (d)  Acknowledges,
      understands and agrees that the existence of the Plan and the execution of
      this
      Agreement are not sufficient by themselves to cause any exercise of any
      Option(s) granted as an Incentive Stock Option to qualify for favorable tax
      treatment through the application of Section 422 of the Internal Revenue Code;
      that Optionee must, in order to so qualify, individually meet by his own action
      all applicable requirements of Section 422, including without limitation the
      following holding period and employment requirements as to Incentive Stock
      Options:

    

    (1)  holding
      period requirement:
      no
      disposition of an Optioned Share may be made by Optionee within two (2) years
      from the date of the granting of the Option(s) nor within one (1) year after
      the
      acquisition of the Optioned Shares through exercise of the Options,
      and

    

    (2)  employment
      requirement:
      at all
      times during the period beginning on the date of the granting of the Option(s)
      and ending on the day three (3) months before the date of exercise, the Optionee
      must have been an employee of the Company, its Parent, or a Subsidiary of the
      Company, or a corporation or a parent or subsidiary of such corporation issuing
      or assuming the Option(s) in a transaction to which Section 425(a) of the
      Internal Revenue Code applies, except where the termination of employment is
      by
      means of the employee's disability, in which case said three (3) month period
      may be extended to six months.

    

    6. Representations
      and Warranties.
      As a
      condition to the exercise of any portion of an Option, the Company may require
      the person exercising such Option to make any representation and/or warranty
      to
      the Company as may, in the judgment of counsel to the Company, be required
      under
      the Securities Act of 1933 or any other applicable law or regulation. Optionee
      hereby represents to the Company that each of the Options evidenced hereby
      and
      the shares purchasable upon exercise thereof are being acquired only for
      investment and without any present intention to sell or distribute such
      securities, that Optionee will sign a lock-up agreement similar to that signed
      by the principal shareholders at the public offering ("PO") of the Company's
      stock as may be required by the underwriters in such PO.

    

    7.  Options
      Not Transferable. No
      Stock
      Option shall be transferable by the Optionee other than by will or by the laws
      of descent and distribution.

    

    8.  No
      Enlargement of Employee Rights.
      Nothing
      in this Agreement shall be construed to confer upon the Optionee (if an
      employee) any right to continued employment with the Company, any future Parent
      or any future Subsidiary, or to restrict in any way the right of the Company,
      any future Subsidiary or any future Parent, to terminate his/her employment.
      Optionee acknowledges that in the absence of an express written employment
      agreement to the contrary, Optionee's employment with the Company may be
      terminated by the Company at any time, with or without cause.

    

    9.  Withholding
      of Taxes.
      Optionee authorizes the Company to withhold, in accordance with any applicable
      law, from any compensation payable to him any taxes required to be withheld
      by
      federal, state or local law as a result of the grant of the Option(s) or the
      issuance of stock pursuant to the exercise of such Option(s).

    

    10.  Laws
      Applicable to Construction.
      This
      Agreement shall be construed and enforced in accordance with the laws of the
      State of California.

    11.  Agreement
      Binding on Successors.
      The
      terms of this Agreement shall be binding upon the executors, administrators,
      heirs, successors, transferees and assignees of the Optionee.

    

    12.  Costs
      of Litigation.
      In any
      action at law or in equity to enforce any of the provisions or rights under
      this
      Agreement or the Plan, the unsuccessful party to such litigation, as determined
      by the court in a final judgment or decree, shall pay the successful party
      or
      parties all costs, expenses and reasonable attorneys' fees incurred by the
      successful party or parties (including without limitation costs, expenses end
      fees on any appeals), and if the successful party recovers judgment in any
      such
      action or proceeding such costs, expenses and attorneys' fees shall be included
      as part of the judgment.

    

    13.  Necessary
      Acts.
      The
      Optionee agrees to perform all acts and execute and deliver any documents that
      may be reasonably necessary to carry out the provisions of this Agreement,
      including but not limited to all acts and documents related to compliance with
      federal and/or state securities laws. Optionee shall be responsible for
      conferring with his or her own tax accountant regarding the tax matters
      pertaining to the Options and the exercise of the Options and shall be solely
      responsible as to all tax filings pertaining to Optionee, including the filing
      of an 83(b) election, if any.

    

    14.  Counterparts.
      For
      convenience this Agreement may be executed in any number of identical
      counterparts, each of which shall be deemed a complete original in itself and
      may be introduced in evidence or used for any other purpose without the
      production of any other counterparts.

    

    15.  Invalid
      Provisions.
      In the
      event that any provision of this Agreement is found to be invalid or otherwise
      unenforceable under any applicable law, such invalidity or unenforceability
      shall not be construed as rendering any other provisions contained herein
      invalid or unenforceable, and all such other provisions shall be given full
      force and effect to the same extent as though the invalid and unenforceable
      provision was not contained herein.

    

    16.  Limitation
      on Value of Optioned Shares.
      Optionee acknowledges that the Plan provides that the aggregate fair market
      value (determined as of the date hereof) of the shares of Common Stock to which
      Options granted as Incentive Stock Options are exercisable for the first time
      by
      Optionee during any calendar year under all incentive stock option plans of
      the
      Company and any future Subsidiary shall not exceed $100,000. It is understood
      and agreed that should it be determined that an Option if granted as an
      Incentive Stock Option hereunder would exceed such maximum, such Option shall
      be
      considered granted as a Non-Qualified Stock Option to the extent, but only
      to
      the extent of such excess. This limitation shall not apply to any option granted
      as a Non-Qualified Stock Option.
