Exhibit 10.6

DOLBY LABORATORIES, INC.

2005 STOCK PLAN

STOCK OPTION AGREEMENT - INTERNATIONAL

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

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

Vesting Schedule :

Subject to Participant continuing to be a Service Provider and other limitations set forth in the Plan, this Stock Option Agreement and country-specific provisions as set forth in Appendix A to this Stock 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 Stock Option Agreement and country-specific provisions as set forth in Appendix A to this Stock Option Agreement (collectively, the “Option Agreement”). Subject to Section 20(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.

1. 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.

2. 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 Tax-Related Items (as defined in section II.F below) withholding 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 Tax-Related Items withholding.

2

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. to the extent permitted by Applicable Law, by cash, check or cash equivalent;

2. consideration received by the Company under a formal cashless exercise program adopted by the Company in connection with the Plan; or

3. any other methods approved by the Administrator and permitted by Applicable Laws.

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.

Regardless of any action the Company or Participant’s employer (the “Employer”) takes with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related withholding items related to Participant’s participation in the Plan and legally applicable to Participant, or deemed by the Company or the Employer to be an appropriate charge to Participant even if technically due by the Company of the Employer (“Tax-Related Items”), Participant hereby acknowledges that the ultimate liability for all Tax-Related Items is and remains Participant’s responsibility and may exceed the amount actually withheld by the Company or the Employer. Participant further acknowledges that the Company and/or the Employer (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Option grant, including, but not limited to, the grant, vesting or exercise of the Option, the issuance of Shares pursuant to such exercise, the subsequent sale of Shares acquired pursuant to such exercise and the receipt of any dividends; and (2) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the Option to reduce or eliminate Participant’s liability for Tax-Related Items or achieve a particular tax result. Further, if Participant has become subject to tax in more than one

3

jurisdiction between the date of grant and the date of any relevant taxable event, Participant acknowledges that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

Prior to any relevant taxable or tax withholding event, Participant shall pay or make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, Participant authorizes the Company and/or the Employer or their respective agents, in their sole discretion and without any notice or authorization by Participant, to satisfy the obligations with regard to all Tax-Related Items by one or a combination of the following:

(1) withholding from Participant’s wages or other cash compensation paid to Participant by the Company and/or the Employer; or

(2) withholding from proceeds of the sale of Shares acquired upon exercise of the Option, either through a voluntary sale or through a mandatory sale arranged by the Company (on Participant’s behalf pursuant to this authorization); or

(3) withholding in Shares to be issued upon exercise of the Option.

To avoid negative accounting treatment, the Company may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding amounts or other applicable withholding rates If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes Participant is deemed to have been issued the full number of Exercised Shares, notwithstanding that a number of the Exercised Shares is held back solely for the purpose of paying the Tax-Related Items due as a result of any aspect of Participant’s participation in the Plan. No fractional Shares will be withheld or issued pursuant to the exercise of an Option and the issuance of Shares thereunder.

Finally, Participant shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of Participant’s participation in the Plan or Participant’s purchase of Shares that cannot be satisfied by the means previously described. Participant acknowledges and agrees that the Company may refuse to honor the exercise and refuse to deliver Shares or the proceeds from the sale of Shares if Participant fails to comply with Participant’s obligations in connection with the Tax-Related Items as described in this section F.

1. Participant acknowledges receipt of a copy of the Plan (including any applicable appendixes or sub-plans thereunder) and represents that he or she is familiar with the terms and provisions thereof, and hereby accepts this Option subject to all of the terms and provisions thereof. Participant has reviewed the Plan (including any applicable appendixes or sub-plans thereunder) and this Option Agreement in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Option and fully understands all provisions of the Option. Participant hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions arising under the Plan or this Option. Participant further agrees to notify the Company upon any change in the residence address in the Notice of Grant.

2. The Company (and not the Employer) is granting the Option. The Company will administer the Plan from outside Participant’s country of residence.

3. The Plan is established voluntarily by the Company, is wholly discretionary in nature and may be modified, amended, suspended or terminated by the Company at any time.

4. The grant of the Option is voluntary and occasional and does not create any contractual or other right to receive future grants of Options, or benefits in lieu of options, even if Options have been granted repeatedly in the past.

5. All decisions with respect to future Option grants, if any, will be at the sole discretion of the Company.

6. The Option and the Shares subject to the Option are extraordinary items that do not constitute compensation of any kind for services of any kind rendered to the Company or the Employer, and which are outside the scope of Participant’s employment contract, if any.

7. The Option and the Shares subject to the Option are not intended to replace any pension rights or compensation.

8. Although provided by the Company, the Option and the Shares subject to the Option are not part of Participant’s normal or expected salary or compensation for any purposes, including, but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end of service payments, bonuses, long service awards, pension, retirement or welfare benefits, or any other similar payments, and in no event should the Option be considered as compensation for, or relating in any way to, past services for the Company, the Employer or any Subsidiary.

9. The Option grant and Participant’s participation in the Plan will not be interpreted to form an employment contract or relationship with the Company or any Subsidiary and the Company will not incur any liability of any kind to Participant as a result of any change or amendment, or any cancellation, of the Plan at any time.

10. The future value of the underlying Shares is unknown and cannot be predicted with certainty.

11. If the underlying Shares do not increase in value, the Option will have no value.

12. If Participant exercises his or her Option and obtains Shares, the value of those Shares acquired upon exercise may increase or decrease in value, even below the Exercise Price.

13. Participant has received the terms and conditions of this Option Agreement and any other related communications in English, and Participant consents to having received

5

these documents in English. If Participant has received this Option Agreement or any other document related to the Plan translated into a language other than English and if the meaning of the translated version is different than the English version, the English version will control.

14. Participant is voluntarily participating in the Plan.

15. In consideration of the grant of the Option, no claim or entitlement to compensation or damages shall arise from forfeiture of the Option resulting from termination of Participant’s status as a Service Provider by the Company or the Employer (for any reason whatsoever and whether or not in breach of local labor laws) and Participant irrevocably releases the Company and the Employer from any such claim that may arise; if, notwithstanding the foregoing, any such claim is found by a court of competent jurisdiction to have arisen, then, by accepting this Option Agreement, Participant will be deemed irrevocably to have waived his or her entitlement to pursue such claim.

16. In the event of termination of Participant’s status as a Service Provider (whether or not in breach of local labor laws), Participant’s right to vest in the Option under the Plan, if any, will terminate effective
