WHEREAS, the Company has adopted and maintains the Skype Global S.à r.l. Equity Incentive Plan (the “Plan”) to
promote the interests of the Company and its Affiliates and shareholders by providing certain Employees of the Company and its Affiliates with an appropriate incentive to encourage them to continue in the employ of the Company or its Affiliates and
to improve the growth and profitability of the Company; 
 WHEREAS, the Plan provides for the Grant to Participants in the Plan
of Non-Qualified Stock Options to purchase Ordinary Shares of the Company. 
 NOW, THEREFORE, in consideration of the premises
and the mutual covenants hereinafter set forth, the parties hereto hereby agree as follows: 
 1. Grant of Options.
Pursuant to, and subject to, the terms and conditions set forth herein and in the Plan, the Company hereby grants to the Participant a NON-QUALIFIED STOCK OPTION (the “Option”) with respect to 3860 Ordinary Shares of the Company.

 2. Grant Date. The Grant Date of the Option hereby granted is 9th August 2010. 

3. Incorporation of Plan. All terms, conditions and restrictions of the Plan are incorporated herein and made part hereof as if
stated herein. If there is any conflict between the terms and conditions of the Plan and this Agreement, the terms and conditions of the Plan, as interpreted by the Board, shall govern. All capitalized terms used and not defined herein shall have
the meaning given to such terms in the Plan. 
 4. Exercise Price. The exercise price of each Ordinary Share underlying
the Option hereby granted is U.S. $ 259.17. 






 5. Vesting Date of Options. The Option shall be fully vested on the Grant Date.

 6. Construction of Agreement. Any provision of this Agreement (or portion thereof) which is deemed invalid, illegal or
unenforceable in any jurisdiction shall, as to that jurisdiction and subject to this section, be ineffective to the extent of such invalidity, illegality or unenforceability, without affecting in any way the remaining provisions thereof in such
jurisdiction or rendering that or any other provisions of this Agreement invalid, illegal, or unenforceable in any other jurisdiction. If any covenant should be deemed invalid, illegal or unenforceable because its scope is considered excessive, such
covenant shall be modified so that the scope of the covenant is reduced only to the minimum extent necessary to render the modified covenant valid, legal and enforceable. No waiver of any provision or violation of this Agreement by the Company shall
be implied by the Company’s forbearance or failure to take action. No provision of this Agreement shall be given effect to the extent that such provision would cause any tax to become due under Section 409A of the Code. 

7. Delays or Omissions. No delay or omission to exercise any right, power or remedy accruing to any party hereto upon any breach
or default of any party under this Agreement, shall impair any such right, power or remedy of such party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default
thereafter occurring nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any
party of any breach or default under this Agreement, or any waiver on the part of any party or any provisions or conditions of this Agreement, shall be in writing and shall be effective only to the extent specifically set forth in such writing.

 8. Limitation on Transfer. The Option shall be exercisable only by the Participant or the Participant’s Permitted
Transferee(s), as determined in accordance with the terms of the Plan (including without limitation the requirement that the Participant obtain the prior written approval by the Board of any proposed Transfer to a Permitted Transferee during the
lifetime of the Participant). Each Permitted Transferee shall be subject to all the restrictions, obligations, and responsibilities as apply to the Participant under the Plan and this Stock Option Grant Agreement and shall be entitled to all the
rights of the Participant under the Plan, provided that in respect of any Permitted Transferee which is a trust or custodianship, the Option shall become exercisable and/or expire based on the Employment and termination of Employment of the
Participant. 
 9. Integration. This Agreement (including Exhibit A), and the other documents referred to herein
or delivered pursuant hereto which form a part hereof contain the entire understanding of the parties with respect to its subject matter. There are no restrictions, agreements, promises, representations, warranties, covenants or undertakings with
respect to the subject matter hereof other than those expressly set forth herein and in the Plan. This Agreement (including Exhibit A), including without limitation the Plan, supersedes all prior agreements and understandings between the
parties with respect to its subject matter.

 10. Counterparts. This Agreement may be executed in two or more counterparts, each of
which shall be deemed an original, but all of which shall constitute one and the same instrument.

SPECIAL PROVISIONS FOR STOCK OPTIONS GRANTED 
 TO PARTICIPANTS IN CERTAIN JURISDICTIONS 
 This Exhibit A includes special terms and
conditions applicable to Participants in the countries below. These terms and conditions are in addition to those set forth in the Stock Option Grant Agreement (the “Agreement”). Any capitalized term used in this Exhibit A without
definition shall have the meaning ascribed to such term in the Skype Global S.à r.l. Equity Incentive Plan, as amended from time to time (the “Plan”) or the Agreement, as applicable. 

This Exhibit A also includes information relating to exchange control and other issues of which Participants should be aware with respect to his or her
participation in the Plan. The information is based on the exchange control, securities and other laws in effect in the respective countries as of January 2010. Such laws are often complex and change frequently. As a result, the Company strongly
recommends that Participants not rely on the information herein as the only source of information relating to the consequences of participation in the Plan because the information may be out of date at the time the Option is exercised or Ordinary
Shares acquired under the Plan are sold. 
 In addition, the information is general in nature and may not apply to the particular situation of
each Participant, and the Company is not in a position to assure Participants of any particular result. Accordingly, Participants are advised to seek appropriate professional advice as to how the relevant laws in his or her country may apply to his
or her situation. Finally, if a Participant is a citizen or resident of a country other than the one in which he or she is currently working, the information contained herein may not be applicable to the Participant.

employer in connection with the Option, consistent with the restrictions and limitations of applicable laws. 
 Further, by accepting the
Option, the Participant agrees that the Company and/or the Participant’s employer may withhold from Option proceeds or collect the fringe benefit tax from the Participant by any of the means set forth in the Agreement or Plan or any other

 Nature of
Scheme. 
 The Company specifically intends that the Plan will not be an occupational retirement scheme for purposes of the Occupational
Retirement Schemes Ordinance (“ORSO”). Notwithstanding the foregoing, if the Plan is deemed to constitute an occupational retirement scheme for the purposes of ORSO, the grant of the Option shall be void. 

Securities Law Information. 
 The Option
and the Shares to be issued upon exercise of the Option do not constitute a public offer of securities and are available only for employees of the Company or an Affiliate. 
 The contents of the Notice, the Agreement, this Exhibit A and the Plan have not been reviewed by any regulatory authority in Hong Kong. The Participant is advised to exercise caution in relation to the

“Due Date”) or such other period specified in Section 222(1)(c) of the U.K. Income Tax (Earnings and Pensions) Act 2003, the amount of any uncollected Tax-Related Items will constitute a loan owed by the Participant to the

Participant further agrees to execute such other joint elections as may be required between the Participant and any successor to the Company and/or its Affiliates. If the Participant does not enter into a Joint Election prior to exercise of the
Option, any purported exercise of the Option shall be null and void without any liability to the Company and/or its Affiliates. The Participant further agrees that the Company and/or its Affiliates may collect the Employer NICs from the Participant

outside of the European Economic Area in the course of the implementation, administration and management of the Plan by agents of the Company or any Affiliate wherever located. 
 Participation in Plan and Employment.

Company or any Affiliate arising out of his or her not being admitted to participation in the Plan which (for the avoidance of all, if any, doubt) is entirely at the discretion of the Board. 

  
 -8-








 The Plan shall not form part of any contract of employment or contract for services between the Company or
any Affiliate and any individual and the rights and obligations of any individual under the terms of his or her office or employment with the Company or any Affiliate shall not be affected by his or her participation in the Plan. 

Participation in the Plan shall be on the express condition that ceasing to participate in the Plan and/or the loss of subsisting Options (or parts
thereof) for any reason in accordance with the terms of the Plan shall not afford any individual rights to compensation or damages under the terms of his or her office or employment with the Company or any Affiliate or otherwise by reason of his or
her Employment.

diminution or extinction of his or her rights or benefits (actual or potential) pursuant to any Option granted to him or her as a result of the exercise or failure to exercise any discretion vested in the Board under the Plan to the advantage or
fullest advantage of the Participant. 
 The Company and each Affiliate shall be entirely free to conduct its affairs as it sees fit without
regard to any consequences under, upon or in relation to the Plan or any Option or Participant.
