DOLBY LABORATORIES, INC.

2005 STOCK PLAN

STOCK OPTION AGREEMENT

Unless otherwise defined herein, the terms defined in the Dolby Laboratories, Inc. 2005 Stock Plan (the “Plan”) shall have the same defined meanings in this Stock Option Agreement (the “Option Agreement”).

Participant:

Address:

Participant has been granted an Option, subject to the terms and conditions of the Plan and this Option Agreement, as follows:

Vesting Schedule:

Subject to Participant continuing to be a Service Provider and other limitations set forth in the Plan and this Option Agreement, this Option may be exercised, in whole or in part, in accordance with the following schedule:

Termination Period:

This Option will be exercisable for three (3) months after Participant ceases to be a Service Provider, unless such termination is due to Participant’s death or Disability, in which case this Option will be exercisable for one (1)

year after Participant ceases to be Service Provider. Notwithstanding the foregoing, in no event may this Option be exercised after the Term/Expiration Date as provided above.

The Administrator hereby grants to Participant named in the Notice of Stock Option Grant (the “Notice of Grant”) an Option to purchase the number of Shares, as set forth in the Notice of Grant, at the exercise price per Share set forth in the Notice of Grant (the “Exercise Price”), subject to the terms and conditions of the Plan, which is incorporated herein by reference, and this Option Agreement. Subject to Section 18(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan and the terms and conditions of this Option Agreement, the terms and conditions of the Plan shall prevail.

If designated in the Notice of Grant as an Incentive Stock Option, this Option is intended to qualify as an Incentive Stock Option under Section 422 of the Code. However, if this Option is intended to be an Incentive Stock Option, to the extent that it exceeds the $100,000 rule of Code Section 422(d), or otherwise does not qualify as an Incentive Stock Option, it shall be treated as a Nonstatutory Stock Option.

(a) Right to Exercise. This Option is exercisable during its term in accordance with the Vesting Schedule set out in the Notice of Grant and the applicable provisions of the Plan and this Option Agreement.

(b) Method of Exercise. This Option is exercisable by (i) delivery of an exercise notice, in the form and manner determined by the Administrator, or (ii) following an electronic or other exercise procedure prescribed by the Administrator, which in either case shall state the election to exercise the Option, the number of Shares in respect of which the Option is being exercised (the “Exercised Shares”), and such other representations and agreements as may be required by the Company pursuant to the provisions of the Plan. Participant shall provide payment of the aggregate Exercise Price as to all Exercised Shares at the time of exercise, together with any applicable withholding taxes arising in connection with such exercise. This Option shall be deemed to be exercised upon receipt by the Company of a fully executed exercise notice or completion of such exercise procedure, as the Administrator may determine in its sole discretion, accompanied by such aggregate Exercise Price and any applicable withholding taxes.

No Shares shall be issued pursuant to the exercise of this Option unless such issuance and exercise complies with Applicable Laws. Assuming such compliance, for income tax purposes, the Exercised Shares shall be considered transferred to Participant on the date the Option is exercised with respect to such Exercised Shares.

Payment of the aggregate Exercise Price shall be by any of the following, or a combination thereof, at the election of Participant:

1. cash;

2. check;

3. other Shares which meet the conditions established by the Administrator to avoid adverse accounting consequences (as determined by the Administrator); or

4. consideration received by the Company under a cashless exercise program implemented by the Company in connection with the Plan.

This Option may not be transferred in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Participant only by Participant. The terms of the Plan

and this Option Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of Participant.

This Option may be exercised only within the term set out in the Notice of Grant, and may be exercised during such term only in accordance with the Plan and the terms of this Option Agreement.

1. Withholding Taxes. Participant agrees to make appropriate arrangements with the Company (or the Parent or Subsidiary employing or retaining Participant) for the satisfaction of all Federal, state, and local income and employment tax withholding requirements applicable to the Option exercise. Participant acknowledges and agrees that the Company may refuse to honor the exercise and refuse to deliver Shares if such withholding amounts are not delivered at the time of exercise.

2. Notice of Disqualifying Disposition of Incentive Stock Option Shares. If the Option granted to Participant herein is an Incentive Stock Option, and if Participant sells or otherwise disposes of any of the Shares acquired pursuant to the Incentive Stock Option on or before the later of (1) the date two years after the date the Option is granted, or (2) the date one year after the date of exercise, Participant will immediately notify the Company in writing of such disposition. Participant agrees that Participant may be subject to income tax withholding by the Company on the compensation income recognized by Participant.

The Plan is incorporated herein by reference. The Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Participant with respect to the subject matter hereof, and may not be modified adversely to Participant’s interest except by means of a writing signed by the Company and Participant. This Option Agreement is governed by the internal substantive laws, but not the choice of law rules, of California.

PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT (AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED AN OPTION OR PURCHASING SHARES HEREUNDER). PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS OPTION AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH IN THE NOTICE OF GRANT DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE WITH PARTICIPANT’S RIGHT OR THE COMPANY’S (OR PARENT’S OR SUBSIDIARY’S) RIGHT TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.

By Participant’s electronic signature and the electronic signature of the Company’s representative, Participant and the Company agree that this Option is granted under and governed by the terms and conditions of the Plan and this Option Agreement. Participant has reviewed the Plan and this Option Agreement in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Option Agreement and fully understands all provisions of the Plan and Option Agreement. Participant hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions relating to the Plan and Option Agreement.
