Akamai has implemented a corporate security policy that is based on the ISO 17799 standard and is substantially equivalent to the MSN Security Policy (version 7.00 revised 1/31/03) provided to Akamai. Akamai will undergo an annual assessment in accordance with ISO 17799 by a 'big four' consulting firm or a reputable equivalent thereto (currently PricewaterhouseCoopers), in either case as selected by Akamai. The costs of the assessment, including without limitation all fees charged by such 5 consultants and all costs and expenses incurred by Akamai in connection with such assessment, shall be borne by Akamai. An executive summary and a formal attestation by the consultant will be made available for Microsoft's review. Microsoft acknowledges that all information relating to the assessment, including the report with respect thereto, the executive summary and the formal attestation, shall constitute confidential information subject to the non-disclosure provisions of the Terms & Conditions. Akamai shall permit Microsoft to review the initial assessment. In the event that Microsoft in its reasonable discretion is not satisfied with the initial assessment because it shows substantial noncompliance with the ISO 17799 standard, then Microsoft may terminate without penalty this Addendum and the New Order Form by written notice delivered to Akamai within five (5) days of the last signature on this Addendum. In the event of a termination by Microsoft pursuant to the foregoing sentence, the parties shall automatically revert to the Original Order Form, as amended by the Addenda. With respect to any future assessment made available for review annually by Akamai to Microsoft, in the event that Microsoft in its reasonable discretion is not satisfied with such assessment because it shows a material decrease in compliance with the ISO 17799 standard compared with the prior year, then Microsoft shall so notify Akamai within fourteen (14) days after receipt of the annual assessment and the parties will negotiate in good faith with the goal of developing an action plan designed to address any agreed upon deficiencies. In the event that the parties are unable to reach agreement on such an action plan then Microsoft may terminate without penalty this Addendum and the New Order Form by written notice delivered to Akamai within 30 days after Microsoft's initial notice regarding non-compliance. Akamai will promptly notify a designated Microsoft security contact of any security breach or similar incident that has, or might have, compromised the privacy or security of any Microsoft end-user personally identifiable information in Akamai's possession. In such event, Akamai will keep Microsoft updated as to the steps being taken to alleviate any continued threat to the privacy or security of such information as well as any actions being taken to prevent foreseeable future incidents. The parties acknowledge that Akamai currently does not transmit any end-user personally identifiable information on behalf of Microsoft. To the extent that Microsoft desires to have Akamai transmit any such information in the future it will so notify Akamai and the parties will discuss and agree on any appropriate security precautions that may be needed with respect to such information. 6 IN WITNESS WHEREOF, and intending to be legally bound hereby, the parties hereto have caused this Amendment to be duly executed and delivered by their respective duly authorized officers as of the date and year first above written.

Ballmer ---------------------- ---------------------- Name: Mike Carlson Name: Steven A. Ballmer Title: Regional Manager Title: CEO Date: 9/13/2004 Date: 09/29/04 7 EXHIBIT A SERVICE LEVEL AGREEMENT I. General a. The Service Level Agreement ("SLA") provisions in this Exhibit A will apply to each Microsoft property executing an order form with Akamai. Each SLA will be measured, and credit amounts calculated, on a property by property basis. b. Microsoft will be responsible for activating the SLA measurement by entering an appropriate test object in the Akamai customer portal (http://control.akamai.com). c. Testing for the purposes of measuring compliance with the SLA will be done using Akamai's testing network, except as otherwise noted below. Data from such testing will be made available to both parties. In the event that a third party is used for testing, any identified SLA violation must be validated by Akamai's logs which will be provided to Microsoft for review. Microsoft will provide prompt notification (within five (5) days of an incident) to Akamai of any SLA violation detected. d. Akamai will not be responsible for any failure to meet Service levels resulting from any negligent or willful act or omission by Microsoft. e. In the event that Microsoft's total fees for Services is less than $[**] in any [**], this SLA will no longer apply and the standard Akamai SLAs will be in force. II. HTTP Service Level Agreement (EdgeSuite Delivery) a. HTTP Service levels will be monitored using two methods: Akamai's internal Akanote System, and third party testing performed by [**], as follows: i. Akamai's Internal Monitoring will be the initial point of reference. In the event that Akamai's monitoring indicates the service levels that they are monitoring have not been met, then such results will be definitive and there will be no need to consult the [**] results. In no event will reference to the two testing methodologies result in duplicate credits being given or SLA violations otherwise being double counted with respect to any particular incident. ii. In the event that the [**] results indicate that the service levels that such tests are monitoring have not been met, then Microsoft will promptly notify Akamai of such fact and the parties will consult Akamai's internal testing logs for the relevant time period. If such logs do not confirm the service level failure identified by the [**] testing, then Microsoft has the option to engage [**]) for additional log analysis or no SLA violation will be deemed to have occurred. If based on the additional log analysis Microsoft, Akamai and [**] are not able to mutually agree that there was a SLA violation, no SLA violation will be deemed to have occurred. iii. For purposes of conducting the [**] tests hereunder, Microsoft will be responsible for the costs associated with, and coordinating the execution of, such testing with the third party vendor. However, Akamai will be provided with access to the relevant testing account to enable Akamai to track the testing hereunder and investigate any potential performance issues. 8 b.

The "CIR" will be defined as the daily minimum committed fees (pro-rated on the basis of the [**] committed level, which ever is greater) for a particular property and a particular service and will be calculated as either (a) the CIR of that property for the affected service based on an order form or amendment or other written agreement entered into directly with the property or (b) if no order form or other written agreement with a separate minimum commitment applies to a particular property's use of a particular service, then the CIR for that property will be deemed to be a proportional amount of the [**] CIR (which ever is greater) applicable to all Microsoft properties not subject to a separate minimum commitment, if any, calculated as the percentage of fees for the affected Service represented by that property (as a percentage of total Microsoft fees for the affected Service for Microsoft properties not subject to a separate commitment) times the [**] CIR (which ever is greater) entered into by Microsoft for the affected Service. If the foregoing calculation would result in a particular Microsoft property having a CIR of zero for a particular service, then the Performance Credit for such property for such service will be equal to [**] of the total fees due by that property in respect of such service during the impacted month. ii. Outage Credit - an Outage Credit will be equal to [**] fees calculated as a percentage of the "CIR" for that property for the affected service only. The 14 "CIR" will be defined as the daily minimum committed fees (pro-rated on the basis of the [**] committed level, which ever is greater) for a particular property and a particular service and will be calculated as either a) the CIR of that property for the affected service based on an order form or amendment or other written agreement entered into directly with the property or b) if no order form or other written agreement with a separate minimum commitment applies to a particular property's use of a particular service, then the CIR for that property will be deemed to be a proportional amount of the [**] CIR (which ever is greater) applicable to all Microsoft properties not subject to a separate minimum commitment, if any, calculated as the percentage of fees for the affected Service represented by that property (as a percentage of total Microsoft fees for the affected Service for Microsoft properties not subject to a separate commitment) times the [**] CIR (which ever is greater) entered into by Microsoft for the affected Service. If the foregoing calculation would result in a particular Microsoft property having a CIR of zero for a particular service, then the Outage Credit for such property for such service will be equal to [**] of the total fees due by that property in respect of such service during the impacted month. b. Service Credits i. Each property entitled to receive a credit under this SLA will receive a Service Credit on the invoice for the impacted month. ii. The Service Credit will be equal to the sum of the Performance Credits for the preceding month and the sum of the Outage Credits for the preceding month (one Outage Credit being awarded for each hour or fraction thereof.) iii. For any given property that has a CIR as determined above, the Service Credit may not exceed 30 days of fees attributable to such property as calculated under "Performance Credit" above. For any given property that has a CIR equal to zero as determined above, the Service Credit may not exceed [**] of the total fees due by that property in respect of such service during the impacted month. iv. Except with respect to the termination rights below, the Service Credit will be Microsoft's sole remedy for any service outage or other failure to meet a defined SLA. 15 c. Termination Microsoft will have the right to terminate its commitment to purchase a particular affected Service (whether reflected in an Order Form, Addendum or otherwise) on 15 days written notice if failure to achieve the Service Levels for such affected Service occurs [**] times in a thirty day period or [**] times in a sixty day period; provided, however that such notice must be delivered within 30 days of the date on which the last failure occurred. 16
