corporation or entity. The “Closing” shall mean the consummation of the
Transaction and the “Transaction Date” or “Closing Date” shall mean the date on
which the Closing takes place.


Due to Executive’s experience and skills, DTS desires
to retain Executive and Executive desires to continue in the employment of DTS
and the Division in order to complete the Transaction and to be available to
provide services that are vital to DTS through and following the Transaction
Date. Therefore, the parties hereby adopt this instrument to amend the
Agreement as set forth herein. All terms of the Agreement remain in full force
and effect, except as modified herein.

  Title:

  	
   

  	
  President, Digital Cinema Division

  
	
  Duties:

  by the President of DTS or designated representative.

  
	
  Base Salary:

  	
   

  	
  Beginning
  January 1, 2007, $240,000 per year payable biweekly and subject to
  payroll deductions as may be necessary or customary in respect of the
  Company’s salaried employees in general.

  



 


Upon
the Closing of the Transaction, and subject to the conditions contained herein,
Executive will be entitled to the further compensation and benefits described
under the applicable Transaction heading contained in this Amendment; provided,
further, that Executive must be continually employed under the terms of the
Agreement and actively engaged in providing the services that are contemplated
hereunder up to and through the Transaction Date. Such compensation and
benefits are in addition to amounts that Executive is otherwise entitled to
receive under the Agreement, unless specified otherwise herein.

Upon the Closing of

Executive’s employment by the DTS for reasons other than cause (as defined in
the Agreement), all stock options will be exercisable for three years following
such termination (but not in excess of the specified maximum term of such
options).













ii)     Vested Awards.   DTS stock options and

Executive’s existing work location without the Executive’s express consent.


II.              Taxes &

Any and all payments to be

voluntarily and DTS acknowledges that Executive may resign at any time.
Similarly, Executive acknowledges that DTS is free to conclude its employment
relationship with Executive at any time DTS deems appropriate. Certain other
terms of Executive’s employment may change with or without notice; provided,
however, this at-will relationship can be changed only in a written agreement
signed by Executive and the President & Chief Executive Officer of
DTS.
