The edge computing network is an [*] consisting of individual [*] ECN Nodes connected to each other, and the Internet, which provides an [*] of services, capacity, and connectivity. Each [*] ECN Node will deliver the following services: large file download, small object/file caching, large object/file caching, network storage, live and on-demand streaming, path /hostname resolution, secure content delivery (SSL/HTTPS), infrastructure management (logging, billing, monitoring, alerting, ticketing, replication, [*]), and dynamic computational services. Each [*] ECN Node will be constructed and operated based on Limelight’s content delivery network architecture and the Limelight Software, with additional functionality as provided by Microsoft.

Each [*] ECN Node will comprise the following major components which provide the ECN functionality:

	i)		[*] ECN Node equipment infrastructure (servers, switches, routers, and miscellaneous) will be procured and owned by Microsoft and based on specifications recommended by Limelight

	ii)		[*] ECN Node space and power procured by Microsoft

	iii)		Network facilities [] and [] (including [], if applicable) providing [] on specifications recommended by Limelight and jointly agreed between Limelight and Microsoft;

	iv)		The Limelight Software hosted within the equipment infrastructure as per (i) above

	v)		Microsoft Edge Computing Services running on Microsoft owned hardware, using Microsoft public and proprietary software;

which, taken together will yield an operational, Microsoft Edge Computing Network which will operate in compliance with the specifications in this exhibit.

Microsoft and Limelight will mutually agree on the scale (traffic, storage, streams, etc) of each service (small object/file caching, streaming, etc) within each [*] ECN Node, and use agreed upon [*] ECN Node Acceptance Criteria (set forth in Exhibit F) to assure the [*] ECN Node is operating at required levels.

Limelight shall (i) monitor each [*] ECN Node for all parameters that Limelight uses to monitor the existing Limelight content delivery network and hosted servers within their nodes, and (ii) provide Microsoft with (A) monitoring test results, (B) ongoing monitoring operational results and (C) recommended actions based on those test results.

CRITERIA FOR DETERMINING ECN NODE READINESS

Limelight will use the ECN process, test and checklist as outlined in Exhibit E. Limelight and Microsoft will jointly develop the specification for each particular [*] ECN Node. Limelight will test the Microsoft instantiated architecture (combination of Limelight Software and Microsoft Hardware Standards) in the Limelight test harness, with the same process and acceptance criteria that Limelight uses to test and accept their own systems. Upon successful testing, Limelight will use the Microsoft instantiation as the basis for its standard deployments. After deployment, Limelight will use the deployment checklist in Exhibit E and successfully conduct the following series of tests (similar to the Content Delivery Service Agreement — Exhibit 4) to ensure the [*] ECN Node is performing at or above that level of service. Once the Node meets all the service level agreement (SLA) requirements Limelight will turn the [*] ECN Node over to Microsoft for acceptance.

Keynote is referenced below — Microsoft and Limelight agreed to use a 3^rd party system such as Keynote or ▇▇▇▇▇ to perform these tests.

Limelight Networks will generate an artificial load of the lesser of (i) two (2) Gbps and (ii) [*] of ECN capacity for 24 hours and run Keynote or ▇▇▇▇▇ against the [*] ECN Node to verify performance and availability.

Microsoft will select from Keynote’s list of standard groups of agents that are generally available and that have at least thirty five (35) geographically and network globally diverse locations in major metropolitan areas (excludes China).

All Keynote test data to be made available via Microsoft’s Keynote test account. For purposes of clarification, all Keynote days are calculated as GMT.

Keynote tests (frequency of one test per hour per agent) will be configured to perform two (2) http GET operations each hour according to the model below:

	a.		A test file (defined in Section (5) below) will be placed on the Microsoft origin server (i.e., ▇▇▇▇▇▇.▇▇▇▇▇▇▇▇.▇▇▇).

	b.		One GET operation will be performed to retrieve the file directly from the origin server (i.e. ▇▇▇▇://▇▇▇▇▇▇.▇▇▇▇▇▇▇▇.▇▇▇/▇▇▇▇▇▇▇▇▇▇).

	c.		The other GET operation will be performed to retrieve the file through the [*] ECN Node, by requesting the object from the appropriate customer hostname CNAMEd to Limelight (i.e., ▇▇▇▇://▇▇▇.▇▇▇▇▇▇▇▇.▇▇▇/▇▇▇▇▇▇▇▇▇▇, where ▇▇▇.▇▇▇▇▇▇▇▇.▇▇▇ is CNAMEd to Limelight and configured to pull content from ▇▇▇▇▇▇.▇▇▇▇▇▇▇▇.▇▇▇)

The Limelight test object will have a TTL of 6 hours or greater.

In the event that this Agreement terminates early such that the Term is less than [*], then the Traffic Commitment shall be reduced pro rata based on the actual time period of the Term of this Agreement as compared to [*] (for example, if the Term is [*], then the Traffic Commitment shall be reduced by [*]).

(d) Including [*] [*] for Traffic Commitment. Section 6(c)(4) of the Original Agreement shall be deleted in its entirety and replaced with the following:

Section 6(c)(4). Failure to [*] Traffic Commitment.

(i) [*]. If, by [*] (the “[*] Traffic Commitment End Date”), Microsoft has not met [*] of the Traffic Commitment (the “[*] Traffic Commitment Minimum”), then, subject to all terms, conditions and limitations in this Agreement, Microsoft shall pay Limelight an amount equal to (i) that amount of the [*] Traffic Commitment Minimum not attained as measured in Mbps multiplied by (ii) the weighted average price per Mbps (that is, total invoiced amount in US dollars, or if in another currency, converted into US dollars, divided by the total traffic in Mbps) using the actual traffic volume and invoiced amounts for traffic applicable to the Traffic Commitment over the [*] months prior to the [*] Traffic Commitment End Date (the “[*] Traffic Commitment Payment”).

(ii) [*]. If, by [*] (the “[*] Traffic Commitment End Date”), Microsoft has not met [*] of the Traffic Commitment (the “[*] Traffic Commitment Minimum”), including any Traffic Commitment satisfied through any prior Traffic Commitment Payments, then, subject to all terms, conditions and limitations in this Agreement, Microsoft shall pay Limelight an amount equal to (i) that amount of the [*] Traffic Commitment Minimum not attained as measured in Mbps multiplied by (ii) the weighted average price per Mbps (that is, total invoiced amount in US dollars, or if in another currency, converted into US dollars, divided by the total traffic in Mbps) using the actual traffic volume and invoiced amounts for traffic applicable to the Traffic Commitment over the [*] months prior to the [*] Traffic Commitment End Date (the “[*] Traffic Commitment Payment”).

(iii) [*] If, by [*] (the “[*] Traffic Commitment End Date”), Microsoft has not met [*] of the Traffic Commitment (the “[*] Traffic Commitment Minimum”), including any prior Traffic Commitment satisfied through any Traffic Commitment Payments, then, subject to all terms, conditions and limitations in this Agreement, Microsoft shall pay Limelight an amount equal to (i) that amount of the [*] Traffic Commitment Minimum not attained as measured in Mbps multiplied by (ii) the weighted average price per Mbps (that is, total invoiced amount in US dollars, or if in another currency, converted into US

Page 4

necessary, for architecting, designing and building the First [*] ECN Node (defined below) integrated with Limelight’s CDN logical locations.

2. [*] ECN Node Space. Microsoft shall be responsible for obtaining space for [*] ECN Nodes (“[*] ECN Node Space”). To assist Microsoft in obtaining [*] ECN Node Space, at Microsoft’s request, Limelight shall give Microsoft notice if the option is available for Microsoft to obtain [*] ECN Node Space through co-location in Limelight content delivery network facilities. If so, then Microsoft’s use shall be under the terms of the form co-location agreement set forth in Exhibit D (the “Form Co-Location Agreement”). In such case, Limelight and Microsoft shall (i) complete the Form Co-Location Agreement for a particular [*] ECN Node or other necessary equipment (e.g., a single server) (the “ECN Node Co-Location Agreement”) and (ii) sign such ECN Node Co-Location Agreement prior to the deployment of the applicable [*] ECN Node for such ECN Node Co-Location Agreement. Once an ECN Node Co-Location Agreement has been executed by both Parties, Microsoft’s responsibility for all charges associated with such [*] ECN Node (except for Support Services) shall be as set forth in the applicable ECN Node Co-Location Agreement.

3. [*] ECN Node Equipment & Connectivity. As part of the Professional Services Limelight provides Microsoft under this Agreement, Limelight shall identify in writing the equipment and connectivity needed for [*] ECN Nodes (“[*] ECN Node Equipment/Connectivity”) and shall update the list of identified [*] ECN Node Equipment/Connectivity from time to time as is reasonably necessary. It shall be Microsoft’s responsibility to obtain [*] ECN Node Equipment/Connectivity.

(b) [*] ECN Node Readiness.

1. Initial Deployment will be One [*] ECN Node. Limelight and Microsoft agree that the initial deployment under this agreement will be one [*] ECN Node [*] (the “First [*] ECN Node”). Limelight and Microsoft further agree that the First [*] ECN Node will be deployed in Microsoft’s [*] facility or such other location in the United States as the Parties agree. The process for accepting the First [*] ECN Node is set forth below. The Parties agree that no subsequent [*] ECN Nodes will be deployed, and Limelight has no obligation to perform, or to continue to perform, any services in support of the deployment of any subsequent [*] ECN Nodes, until after Microsoft has accepted the First [*] ECN Node and has issued the Limelight Software Acceptance.

2. Subsequent Deployment of [*] ECN Node. Upon completion of a [*] ECN Node (including, for purposes of clarity, the First [*] ECN Node), Limelight shall provide Microsoft an ECN Node Readiness Certificate in the form of Exhibit E along with all materials supporting such ECN Node Readiness Certificate. The completion criteria that Limelight shall use in assessing ECN Node readiness shall be substantially the same as the criteria that Limelight uses in assessing the readiness of its own new CDN logical locations (the “Readiness Criteria”). The current criteria that Limelight uses in assessing the readiness of its own new CDN logical locations are provided in Exhibit F and may be updated by Limelight from time to time upon notice to Microsoft. Microsoft shall have [*] after Limelight has issued the ECN Node Readiness Certificate to either (i) accept the ECN Node Readiness Certificate (a “[*] ECN Node Acceptance”) or (ii) dispute in good faith the actual readiness of the [*] ECN Node by

Confidential

[*]

Page 5

specifying in writing and with reasonable detail how the [*] ECN Node fails to meet the Readiness Criteria (a “[*] ECN Node Rejection”). If Microsoft does not submit a [*] ECN Node Acceptance or [*] ECN Node Rejection to Limelight within the notice period set forth in the preceding sentence, then it shall be deemed that the [*] ECN Node has been accepted. If Microsoft issues a [*] ECN Node Rejection, then Limelight shall have up to [*] to provide conclusive evidence that such [*] ECN Node actually meets the Readiness Criteria. After providing such conclusive evidence, Limelight shall issue the ECN Readiness Certificate for such [*] ECN Node and the [*] ECN Node Acceptance shall be deemed issued for such [*] ECN Node. If Limelight repeatedly fails to deliver any [*] ECN Node with an ECN Node Readiness Certificate accepted by Microsoft within the mutually agreed dates set in accordance with this Agreement, then, unless such failure is caused by Microsoft’s failure to meet its obligations in Section 2(b)(4), Microsoft may, at its option: (i) accept and retain the [*] ECN Node with all rights and obligations as set forth in this Agreement for such [*] ECN Node; (ii) extend the period for acceptance; or (iii) except for cases where the failure to deliver any [*] ECN Node with an ECN Node Readiness Certificate accepted by Microsoft within the mutually agreed dates set in accordance with this Agreement is caused by Force Majeure, terminate this Agreement for cause pursuant to Section 17, provided, however, that, if Microsoft elects to terminate this Agreement under the circumstances provided for in this section, Microsoft need not provide Limelight the cure period specified in Section 17 and Microsoft will only be responsible for those charges that have accrued as of the termination date. For purposes of clarity, Microsoft’s selection of an option (as set forth in the immediate preceding sentence) for one [*] ECN Node, shall not dictate the option, if any, Microsoft may chose for any other applicable [*] ECN Node.

3. After Issuing the ECN Node Readiness Certificate. Within a reasonable period of time after issuing the ECN Node Readiness Certificate, Limelight shall (i) to the extent practicable, manage the routing of user content requests for Microsoft-delivered content to the applicable (based on standard criteria, such as logical Internet location and [*] ECN Node availability) [*] ECN Node, (ii) to the extent practicable, manage the satisfaction of user content requests for Microsoft-delivered content from the applicable (based on standard criteria, such as logical Internet location and [*] ECN Node availability) [*] ECN Node; (iii) manage such [*] ECN Node, (iv) monitor the [*] ECN Node for the parameters set forth in Exhibit F, and, (v) deliver all such monitoring results to Microsoft. Limelight will utilize a process for integrating new [*] ECN Nodes into the integrated delivery infrastructure that is similar to Limelight’s own process for integrating its own new CDN logical locations into its infrastructure. This process may include beginning with a minority of deliverable content and gradually increasing the content delivered through the node/location over a period of time, until reaching full utilization of the node/location. At any time that Limelight determines that a [*] ECN Node is not ready for production utilization or is operating in a substandard fashion, or at any time that Microsoft reasonably believes that a [*] ECN Node is not ready for production utilization or is operating in a substandard fashion and so notifies Limelight, Limelight may reduce its utilization of, or cease utilizing completely, that [*] ECN Node until Limelight is able to restore the [*] ECN Node to full readiness. For clarity, all communications facilities charges related to [*] ECN Nodes, including collocation charges, Internet connection charges, variable charges based on traffic and network utilization, network facilities connecting the [*] ECN Node to the Limelight network, and all other charges, shall be (if [*] ECN Node Space is obtained through co-location in Limelight content delivery network facilities) as set forth in the applicable ECN Node Co-Location Agreement or paid as set forth in Section 2(e), and if Microsoft obtains [*] ECN Node Space independently of Limelight, then Microsoft shall be independently responsible for these charges.

4. Microsoft Responsibility in ECN Node Readiness. Microsoft acknowledges it has certain responsibilities set forth in Exhibit A-2 that are important in helping ensure each [*] ECN Node is capable of receiving an ECN Node Readiness Certificate (the “Microsoft Responsibilities”). Microsoft and Limelight shall communicate with reasonable frequency about the scope and definition of the Microsoft Responsibilities and Microsoft’s progress in discharging the Microsoft Responsibilities for each [*] ECN Node. Microsoft and Limelight shall amend in writing the definition of the Microsoft Responsibilities as is reasonably necessary (i) within [*] of the Effective Date, and/or (ii) within [*] of the issuance of a [*] ECN Node Acceptance for the First [*] ECN Node. Microsoft shall use commercially reasonable efforts to discharge the Microsoft Responsibilities. In the event that [*] prior to a scheduled [*] ECN Node delivery date Microsoft has not discharged the Microsoft Responsibilities for such [*] ECN Node after the exercise of commercially reasonable efforts, then Microsoft and Limelight shall discuss strategies and alternatives to the given [*] ECN Node, including, but not limited to, deploying such [*] ECN Node in another location.

Page 7

(c) [*] ECN Node Support Services. Limelight shall provide Microsoft services (“Support Services”) to support and maintain [*] ECN Nodes, and the Services defined in the Limelight Content Delivery Service Agreement, all consistent with the specifications, timelines, service levels, and other requirements contained in Exhibit B-1 to this Agreement (“Microsoft Edge Computing Network Support Services”). Limelight will provide to Microsoft (i) Tier 1, Tier 2, and Tier 3 Support Services (as set forth in Exhibit B-1) for the period commencing on the Effective Date plus two months and ending [*] later, and (ii) Tier 3 Support Services for the period commencing [*] after the Effective Date plus two months and ending [*] later.

(d) New Features for Limelight Software. Except as expressly set forth in Section 3(e), Limelight has no obligation to modify Limelight Software, including, but not limited to, providing new functionality, revised functionality, and earlier implementation of planned functionality.

(e) Committed Amount of Services; Catch Up Payment; Maximum Service Hours. Microsoft shall have the right to use Professional Services, of the type and up to the maximum number of hours for each type of Professional Services as specified in Exhibit B-2, from the Effective Date through July 31, 2010 (the “Professional Services Fee End Date”) for the purpose of fully deploying twenty-four (24) [*] ECN Nodes resulting in total Professional Services Fees of $[*] (except as set forth below). Limelight shall report to Microsoft (i) monthly on the hours for each type of Professional Service used for such month, and (ii) quarterly on the total hours used as compare to the allocation, projection and maximum number of hours for each type of Professional Services as set forth in Exhibit B-2. At Microsoft’s election, Limelight will meet and discuss the number of hours of Professional Services used with the objective of helping ensure that all [*] ECN Nodes will be deployed without the need for any Additional Professional Services Payment, and the Parties will use good faith efforts to adjust staffing for Professional Services to meet that goal and the objectives of this Agreement. In the event that as of the Professional Service Fee End Date this Agreement has not been terminated and Limelight is not in material breach of this Agreement, then such Professional Services will be deemed fully utilized by Microsoft and all Professional Services Fees will be deemed fully earned by Limelight as of the Professional Service Fee End Date, whether or not all [*] ECN Nodes have been deployed, and Microsoft shall pay Limelight an amount equal to $[*] minus the total amount of Professional Fees accruing as of the Professional Service Fee End Date (the “Catch Up Payment”). In the event that Microsoft utilizes Professional Services such that the type and total hours at the corresponding hourly rate of Professional Services (as set forth in Exhibit B-2) totals $[*] or more, then Microsoft shall pay for any additional Professional Services in excess of $[*] at the applicable hourly rates set forth in Exhibit B-2 (the “Additional Professional Services Payment”). Microsoft will pay the Catch Up Payment and any Additional Professional Services Payment under the terms of Section 5(c)-(e), subject to Limelight’s submission of an invoice, as set forth in Section 5(d).

(f) Additional Items. Modifications to any exhibits may be added to this Agreement from time to time with the mutual written agreement of Limelight and Microsoft and, when so added, such modifications will become part of the applicable exhibit to which it pertains. Except for Fees and Advance set forth in Section 5 (but including all other obligations in Section 5), Limelight shall be responsible at its own cost for any and all equipment and/or software necessary to adequately perform its obligations under this Agreement. Upon Microsoft’s request, Limelight will meet with Microsoft to review Limelight’s performance and any issues

Confidential

[*]

Confidential Treatment Requested

Page 8

related to Limelight’s compliance with the performance standards in this Agreement (including, without limitation, the Microsoft Edge Computing Support Services, as set forth in Exhibit B-1). Limelight agrees that it will not use any Microsoft facilities and/or any Microsoft-provided equipment (including any equipment owned, leased or rented by Limelight for performing its obligations under this Agreement) to perform services for any person or entity other than Microsoft, without the prior written consent of Microsoft. In the event Microsoft provides Limelight with Microsoft equipment for Limelight’s use in the performance of its obligations under this Agreement, Limelight assumes the risk of loss, damage, theft or disappearance for all such Microsoft equipment while in Limelight’s care, custody or control. In addition, Limelight shall take no actions which affect Microsoft’s title or interest in such Microsoft equipment.

(g) Project Reviews; Personnel. Microsoft and Limelight will meet reasonably frequently, but at least weekly (decreasing to monthly after [*] of this Agreement), to review the project objectives, scope and schedule; update or modify the schedule as needed; and to review the status of performance for meeting the schedule and other requirements set forth in this Agreement. For purposes of clarity, nothing in this section shall be construed as permitting an informal process for amending this Agreement. Amendments to this Agreement may be made only as set forth in Section 21(g). The Parties will create and send a single project report containing risks and issues to identified team members at Microsoft and Limelight. Reasonably soon after the Effective Date, but not later than [*], Limelight shall designate a project program manager who shall be responsible for coordinating this meeting and creating the report referenced in this section. Limelight may modify the designation of the project program manager from time to time. Limelight agrees that it will consider Microsoft feedback regarding any Limelight employee or Subcontractor.

(h) Financial Information. In the event that ▇▇▇▇▇▇▇▇▇ learns that it has become or will become insolvent, then, within [*] after Limelight so learns, Limelight shall submit financial statements to Microsoft in sufficient detail to allow Microsoft to determine whether Limelight shall be capable of continuing to perform its obligations hereunder, if and to the extent such detailed financial statements are available to Limelight.

(i) Non-Exclusivity; No Other Minimums. The Parties hereto agree that nothing contained in this Agreement shall be construed as (i) creating an exclusive relationship between the Parties or (ii) except as expressly set forth in Section 6(c), requiring Microsoft to obtain any minimum level of services from Limelight.

(j) Additional Terms and Conditions for Professional Services. All obligations of Limelight under this Agreement to provide services of any kind, whether consulting, advising, recommending, assisting, developing software or requirements, or any other activity of any kind that requires the work of individuals (except sales activities), will be performed by Limelight by providing Professional Services. Such Professional Services are limited to the type and the maximum number of hours for each type of Professional Services as set forth in Exhibit B-2, and are billable to Microsoft as set forth in Section 2(e) and Section 5(a)(1).

5(a)(3) (Payment of Software License Fee) and Section 17 (d) (Termination/Survival of Limelight Software License).

(d) Limelight Software Delivery & Acceptance. Promptly after the execution of this Agreement, but not later than [*], Limelight shall deliver the Limelight Software to Microsoft in [*] only (along with an offer to provide a complete machine-readable copy of the corresponding [*] solely for the open source software modules listed in Exhibit C-1), along with a list of all software required to make the Limelight Software fully operational that Limelight does not deliver. The date on which Limelight initially delivers the Limelight Software and list of other software to Microsoft will be the “Limelight Software Delivery Date.” Promptly after the Limelight Software Delivery Date, Microsoft shall commence deploying the Limelight Software in an internal, production test environment for the purpose of having the Limelight Software fully operational in such production test environment (the “Successful Test Deployment”). After (i) the Successful Test Deployment, and (ii) Microsoft’s issuance of the ECN Node Acceptance for the First [*] ECN Node (satisfaction of both being the “Limelight Software Acceptance”), the Limelight Software License Fee shall be due as set forth in Section 5(a)(3), and Limelight will deliver the Limelight Software to Microsoft in [*] and [*]. Microsoft may notify Limelight at any time of any potential defect it identifies in the Limelight Software (each such potential defect being a “Software Error”) by notifying Limelight in writing or by opening a ticket on Limelight’s electronic incident reporting system, providing as much detail as is reasonably possible. Limelight shall respond to Software Error notifications within a reasonable period of time. Software Errors that are not actual software defects, but that reflect the correct operation of the Limelight Software, will not be corrected. Any Software Error reported during the Term that is identified by Limelight as constituting an actual software defect will be corrected by Limelight within a reasonable period of time. If Limelight repeatedly fails to correct Software Errors that preclude either the Successful Test Deployment or the Limelight Software Acceptance, then Microsoft may, at its option: (i) accept and retain the Limelight Software with all rights and obligations as set forth in this Agreement for such Limelight Software by issuing the Limelight Software Acceptance; or (ii) terminate this Agreement for cause pursuant to Section 17, provided, however, that, if Microsoft elects to terminate this Agreement under the circumstances provided for in this section, Microsoft need not provide Limelight the cure period specified in Section 17 and Microsoft will only be responsible for those charges that have accrued as of the termination date. For purposes of clarity, Microsoft’s selection of an option (as set forth in the immediate preceding sentence) for Successful Test Deployment, shall not dictate the option, if any, Microsoft may chose for Limelight Software Acceptance.

(e) Limelight Software Updates & Documentation. Commencing after the Effective Date, Limelight shall provide Microsoft (i) [*], and (ii) all error corrections, bug fixes, enhancements, revisions or modifications to the Limelight Software, all in [*] and [*], that Limelight makes to the Limelight Software through the Term, and (iii) all error corrections intended to mitigate software defects that directly and adversely affect the core service operation, that Limelight makes in its own deployed instance(s) of the Limelight Software, to the extent that such error corrections are separately identifiable as applicable solely to the Limelight Software, all in [*] and [*], occurring during the Term (subpart (ii) and (iii) are each a “Fix,” and collectively with the Limelight Software [*], the “Updates”). For purposes of clarity, nothing in this Agreement shall be construed as requiring

Confidential

Page 11

Limelight to release Limelight Software [*]. Limelight shall have no obligation to create any error correction or update to any of the Limelight Software after the Term, whether or not Microsoft identifies a software error after that date. Microsoft understands and acknowledges that Limelight may in the future replace some or all modules of the Limelight Software within Limelight’s own operations, and that once Limelight has replaced a module of the Limelight Software with a replacement module, that Limelight will make no further error corrections to, or updates to, the replaced module. Also, in the event that Limelight deploys Limelight Software [*], then Limelight will cease supporting the first version of the Limelight Software a reasonable time after the later of the date that: (i) Limelight delivers Microsoft Limelight Software [*]; and (ii) Limelight fully deploys Limelight Software [*] throughout its own production environment. In no event shall Limelight be required under this Agreement to develop Limelight Software error correction due to a problem that is not attributable to Limelight. Limelight shall provide Microsoft with reasonable access to intermediate check-ins, final-form [*], designs, diagrams, specifications, requirements, test plans, prototypes and development history for the Limelight Software for which Limelight has the right to disclose [*], and will identify all other software used in or relied upon in the Limelight Software which is currently deployed and operated within the Limelight contend delivery network.

(f) Microsoft Modification of Limelight Software. In the event that Microsoft modifies the Limelight Software, then Microsoft, in its sole discretion, may elect to deliver source and [*] for such modifications to Limelight under the license set forth in this section. For purposes of clarity, nothing in this section shall be construed as requiring Microsoft to deliver or license to Limelight any software, including modifications of the Limelight Software. Subject to the provisions of this Agreement, in the event that Microsoft delivers its modifications of the Limelight Software to Limelight, in either source or [*], then with respect to such delivered software (the “Microsoft Modifications”), Microsoft hereby grants Limelight a perpetual, non-exclusive, non-assignable, nontransferable, worldwide, personal, limited license to use the Microsoft Modifications solely for Limelight’s content delivery network service. In the event that Microsoft licenses Microsoft Modifications to Limelight under this section and Limelight chooses to use such Microsoft Modifications, then, subject to appropriate Limelight business and strategic evaluation, functional evaluation, review, testing and other quality assurance activities, Limelight will use commercially reasonable efforts to evaluate the Microsoft Modifications for deployment in, or in conjunction with, Limelight’s deployment of Limelight Software, provided that, such deployment of Microsoft Modifications does not interfere with, conflict with, negatively affect, or otherwise harm Limelight’s business, operations, financial performance, or industry reputation; and if necessary and if Limelight has elected to deploy the Microsoft Modifications, Limelight will use commercially reasonable efforts to enable Microsoft, at Microsoft’s expense, to deploy additional systems within Limelight’s service delivery infrastructure which can communicate directly with Microsoft Modifications, provided that such systems do not interfere with, conflict with, or otherwise harm Limelight’s business.

(g) Microsoft Caused Software Errors. In the event that Microsoft reports to Limelight or Limelight otherwise identifies a Software Error (for example, due to degraded performance) and such Software Error is found to have been contained within or caused by Microsoft’s modification of the Limelight Software, then any Tier 3 engineering resources used to identify and resolve or otherwise correct such Software Error shall be chargeable as

Professional Services as set forth in this Agreement. For purposes of clarity, any Tier 3 engineering resources used to identify and resolve or otherwise correct any other Software Errors, including those caused by Microsoft Modifications that Limelight introduces into the Limelight Software code base will not be chargeable as Professional Services.

4. OTHER SOFTWARE

(a) Enhanced [*] Manager. Limelight and Microsoft may elect to [*] based on Limelight’s [*]. If the Parties so elect, then the Parties shall establish a written program and agreement, manually signed by each Party, for [*] a specification for the Enhanced [*] Manager, a schedule for [*] Enhanced [*] Manager, a list of persons assigned to perform program management, software development and testing, and including such other details as are reasonably necessary for [*]. All Intellectual Property Rights that are created, developed, written, conceived or first reduced to practice as a result of [*] Enhanced [*] Manager [*] shall be allocated as expressly set forth in the written agreement for such Enhanced [*] Manager [*].

(b) Other Microsoft Software. If Microsoft provides software, related materials or other items (such as documentation, photographs, music, graphics, multimedia, prototypes, or demos) for Limelight’s use to perform Services, other than Microsoft Modifications (which is governed by Section 3(f)) or the Enhanced [*] Manager (which is governed by Section 4(a)), then Limelight’s use of the software or item shall be governed by the license which is contained in it or accompanies such software or item when delivered to Limelight. If no such license exists, then Microsoft grants Limelight a nonexclusive, nontransferable, non-assignable, limited license to use the software or item, as appropriate, solely for the purpose of creating and performing Services. Such license rights do not include any license, right, power or authority to subject the Microsoft software or item, in whole or in part, to any terms of an Excluded License. Microsoft or its suppliers retain all right, title, and interest in and to the software or item. “Excluded License” means any license requiring, as a condition of use, modification and/or distribution of the software subject to the license, that such software or other software combined and/or distributed with it be (a) disclosed or distributed in [*] (b) licensed for the purpose of making derivative works; or (c) redistributable at no charge.

(c) Microsoft Products. In the event that Limelight makes proposals for enhancements to, and/or additional functionality for, Microsoft software products which are designed to improve the delivery performance, data accuracy, cost efficiency, and/or revenue productivity/yield of the Limelight content delivery network or the Microsoft edge computing network, then Microsoft shall use good faith efforts to receive and, as appropriate, consider such proposals.

5. LIMELIGHT FEES.

(a) Fees and Rates. Microsoft shall pay Limelight the fees set forth in Section 5(a)(1-3) (collectively, the “Fees”) in accordance with the terms of this Agreement, including, but not limited to, Sections 5(c)-(e):

1. Professional Service Fees. For each [*] ECN Node that Microsoft issues a [*] ECN Node Acceptance, Microsoft shall pay Limelight a one-time fee for Professional Services (“Professional Services Fees”) in the amount of:

Page 13

	i.		[] UNITED STATES DOLLARS (US$[] for [] ECN Nodes [];

	ii.		[] UNITED STATES DOLLARS (US$[] for [] ECN Node number [];

	iii.		[] UNITED STATES DOLLARS (US$[] for [] ECN Nodes number [];

	iv.		[] UNITED STATES DOLLARS (US$[] for [] ECN Nodes number [];

	v.		[] UNITED STATES DOLLARS (US$[] for [] ECN Nodes number [];

If Microsoft issues ECN Node Acceptances for less than [*] ECN Nodes, then the provisions of Section 2(e) shall apply. The Professional Services Fees for [*] ECN Nodes number [*] and above shall be that amount mutually agreed to by Limelight and Microsoft in writing prior to commencing any Professional Services for such [*] ECN Nodes. Limelight will separately invoice Microsoft for the reasonable and actual expenses it incurs in providing the Professional Services under this agreement, including, but not limited to, travel, lodging and meals, and, provided that Limelight complies with the MVG for such expenses, such invoices will be paid as set forth in Section 5(c)-(e).

2. Support Services Fees. For each [*] ECN Node that Microsoft issues a [*] ECN Node Acceptance, Microsoft shall pay Limelight a one-time fee for Support Services rendered during the Term (“Support Services Fees”) in the amount of [*] DOLLARS (US$[*] for each [*] ECN Node number [*]. The Support Services Fees for [*] ECN Nodes number [*] and above shall be that amount mutually agreed to by Limelight and Microsoft in writing prior to commencing any Support Services for such [*] ECN Nodes. By way of example, if, during the Term, Microsoft issues [*] ECN Node Acceptances for [*] ECN Nodes, then Limelight would have earned Support Service Fees totaling $[*]; and, on the other hand, if, during the Term, Microsoft issues [*] ECN Node Acceptances for [*] ECN Nodes, then Limelight would have earned Support Service Fees totaling $[*]. For purposes of clarity, Limelight is responsible for any expenses it incurs in providing the Support Services under this agreement, including, but not limited to, travel, lodging and meals.

3. Software License Fee. After Microsoft issues the Limelight Software Acceptance, Microsoft shall pay Limelight a one-time fee to license the Limelight Software (the “Limelight Software License Fee”) in the amount of [*] UNITED STATES DOLLARS (US$[*] payable in two installments as follows:

	i.		[] UNITED STATES DOLLARS (US$[] shall accrue on [] of the [] ECN Node Acceptance for the First [*] ECN Node; and

	ii.		[] UNITED STATES DOLLARS (US$[] shall accrue on the date that is [] after the date of issuance of the [] ECN Node Acceptance for the First [*] ECN Node.

For purposes of clarity, the Limelight Software License Fee is the entire payment Microsoft will owe Limelight for Limelight Software license fees, including, Limelight Software [*], if any, or any other Update, regardless of how many Updates Limelight

Confidential

[*]

Page 14

delivers and/or Microsoft accepts. For purposes of clarity, in the event this Agreement terminates or expires prior to Microsoft’s issuance of the Limelight Software Acceptance, then Microsoft will have no obligation to pay the Limelight Software License Fee and the Limelight Software License shall expire as of the date of termination or expiration, as applicable, of this Agreement.

(b) Advance Against Service Fee. As of the Effective Date, Microsoft shall pay Limelight a refundable advance of [*] UNITED STATES DOLLARS (US$[*] (the “Advance”). Limelight shall invoice Microsoft for the Advance, and such invoice will be paid as set forth in Section 5(c)-(e). Microsoft may offset the Advance against the Professional Service Fees by offsetting $[*] against each of the two payments of $[*] due upon Microsoft’s acceptance of [*] ECN Nodes numbers [*]. In the event that by the earlier of [*] and the termination date of this Agreement, Limelight Professional Service Fees ▇▇▇▇▇▇▇▇ have not been sufficient to offset the entire amount of the Advance, then Limelight shall promptly (but not later than [*]) pay Microsoft the amount of the non-offset portion of the Advance upon written notice by Microsoft.

(c) Payment Terms. Limelight shall invoice Microsoft for Professional Services Fees, Support Services Fees and Limelight Software License Fee as each accrues under this Agreement. Limelight shall invoice Microsoft for all other Fees incurred for Services during a month on or after the [*] of the month following the month in which the Services were provided. Upon receipt of a correct and undisputed invoice, Microsoft shall pay the invoice net [*] from the date of the invoice. Payments shall be made according to Microsoft’s then-current payment policies, which include payment via ACH electronic payment to Limelight’s financial institution under instructions supplied by Limelight in Microsoft’s ACH Electronic Payment form.

(d) MS Invoice. Limelight shall invoice Microsoft for all amounts via the MS Invoice online tool in accordance with the then-current requirements at ▇▇▇▇://▇▇▇▇▇▇▇.▇▇▇▇▇▇▇▇▇.▇▇▇. All invoices shall be submitted with line-item detail identifying all aspects of the Service provided to Microsoft. Invoices shall not bear an invoice date earlier than the date on which Limelight shall be entitled to be paid under this Agreement, or if not specified, invoices may be issued monthly in arrears.

(e) Disputed Amounts. Microsoft may dispute any invoice by providing written notice to Limelight within [*] of receiving the invoice (each a “Disputed Amount”). All Disputed Amounts that Microsoft agrees in writing to pay, or that are required to be paid pursuant to a final court order or arbitration award (along with any other amounts legally required, e.g., by statute or under this Agreement), shall be paid on the payment terms in Section 5(c)-(d). Payment of an invoice without asserting a dispute is not a waiver of any claim or right. Failure to dispute an invoiced amount within the [*] period shall not be deemed a waiver of any claim unknown to Microsoft at the time.

6. LIMELIGHT CONTENT DELIVERY SERVICE AGREEMENT AMENDMENTS. The Parties amend the Limelight Content Delivery Service Agreement, as more fully set forth in this section.

Confidential

[*]

Page 15

(a) Service Fee. All pricing is as set forth in the Limelight Content Delivery Service Agreement.

(b) Contract Pricing Adjustment. Limelight and Microsoft agree that they will meet to discuss adjusting the prices recited in the Limelight Content Delivery Service Agreement [*] (and such other additional times as the Parties agree) to reflect any change in market prices for CDN services of the amount and type contained herein. The Parties acknowledge that any changes in pricing will have an inverse effect on the balance of the Traffic Commitment; that is, an increase in pricing will result in a decrease in the balance of the Traffic Commitment, and a decrease in pricing will result in an increase in the balance of the Traffic Commitment. Such adjustment to pricing and the balance of the Traffic Commitment shall be made via a written amendment to the Limelight Content Delivery Service Agreement (for adjustments to pricing) and this agreement (for adjustments to the Traffic Commitment) and shall be effective as of [*], unless such written amendment is agreed [*] of that year, in which case such change shall be effective as of the first day of the calendar quarter in which such written amendment is actually reached. If Limelight and Microsoft are not able to agree as to the terms of an amendment to adjust the prices recited in the Limelight Content Delivery Service Agreement and the balance of the Traffic Commitment, then the prices contained in the Limelight Content Delivery Service Agreement and the balance of the Traffic Commitment will remain in effect until such time as the Parties are able to reach an agreement. If Limelight and Microsoft agree that no change in the prices recited in the Limelight Content Delivery Service Agreement is warranted, then no amendment to this agreement need be executed.

(c) Traffic Commitment. During the time period commencing on [*] and ending [*] from the Effective Date, and subject to terms, conditions and limitations set forth in this Agreement, Microsoft shall meet the Traffic Commitment, defined below.

1. Definition. “Traffic Commitment” means total usage of CDN Services, where Services are as defined in and used under the Limelight Content Delivery Service Agreement for all Microsoft properties and/or online services in all markets worldwide representing the sum of the billable traffic rate calculated for each month (except for Excluded Service Traffic, defined below) and equal to [*] Mbps-months over the time period starting [*] (the “Traffic Commitment Start Date”), and ending [*] from the Effective Date (the “Traffic Commitment End Date”), subject to any adjustments as set forth in this Agreement. “Excluded Service Traffic” means (i) the traffic in Mbps for [*] for any Service, as defined under the Limelight Content Delivery Service Agreement (the “[*] Traffic”) plus the traffic for [*] Interactive News, LLC for any Service, as defined under the Limelight Content Delivery Service Agreement (the “[*] Traffic”) up to a maximum of [*] Mbps, and (ii) the traffic for any acquisition by Microsoft of an existing Limelight customer up to a maximum of the average traffic over the last six (6) months prior to such acquisition for those specific services such customer was using immediately prior to such acquisition, provided that Limelight promptly notifies Microsoft in writing that such acquisition was an existing Limelight customer. For example, if in a given month the [*] Traffic equals [*] Mbps for small object/file caching and the [*] Traffic equals [*] Mbps for small object/file caching, then the amount of Excluded Service Traffic equals [*] Mbps-months of Excluded Traffic for that month. For further example, if, in a given month the [*] Traffic equals [*] Mbps for small object/file caching and the [*] Traffic equals [*] for small object/file caching, then the amount of Excluded Service

Confidential

[*]

Page 16

Traffic equals the Actual [*] Traffic of [*] the Actual [*] Traffic of [*] Mbps-months of Excluded Traffic for that month. For clarity as to how to calculate Mbps-months for Services under this Agreement, if Limelight bills Microsoft for [*] Mbps for Services (in all cases, excluding Excluded Service Traffic) in [*], then that month will represent [*] Mbps-months of performance against the Traffic Commitment; if Limelight then bills Microsoft for [*] Mbps for Services in [*] then that month will represent [*] Mbps-months of performance against the Traffic Commitment and [*] will represent [*] of performance against the [*]; and if Limelight then bills Microsoft [*] Mbps for Services in [*], then that month will represent [*] Mbps-months of performance against the Traffic Commitment and the [*] will represent [*] Mbps-months in total performance against the Traffic Commitment.

2. Adjustments to Traffic Commitment.

i. Reduction. In the event that this Agreement terminates early such that the Term is less than [*], then the Traffic Commitment shall be reduced pro rata based on the actual time period of the Term of this Agreement as compared to [*] (for example, if the Term is [*], then the Traffic Commitment shall be reduced by [*], or [*]). In the event that Limelight fails to meet the service level agreement for any Service under the Limelight Content Delivery Service Agreement in any calendar month for a particular Microsoft property, then the Traffic Commitment shall be reduced by an amount equal to (i) the traffic for such Microsoft property in the month immediately preceding the calendar month Limelight failed to meet such service level agreement, multiplied by (ii) three (3).

ii. GB Pricing Conversion. For purposes of satisfying the Traffic Commitment (which, of course, is measured in Mbps), the amount of Mbps that applies to the Traffic Commitment for all traffic which Microsoft pays under a per Gigabyte (GB) billing model, but not including storage services paid for under a per Gigabyte (GB) billing model, shall be determined using the following formula: [*] for traffic under the [*] divided by the corresponding then current standard [*]” is the volume of traffic to be applied to the [*] for that month. Storage services paid for under a per Gigabyte (GB) billing model do not count towards the Traffic Commitment.

3. Reporting. Each month after the Traffic Commitment Start Date, by the [*] of the month, Limelight shall report (the “Traffic Commitment Report”) to Microsoft (i) the amount of Traffic Commitment Microsoft attained for the month, (ii) the total amount of the Traffic Commitment Microsoft has attained, and (iii) the amount of the Traffic Commitment remaining. If Microsoft disputes any aspect of the Traffic Commitment Report, then Microsoft shall notify Limelight of such dispute, and the Parties shall in good faith work to mutually agree on the correct figures for the Traffic Commitment Report.

4. Failure to Attain. If, by the Traffic Commitment End Date, Microsoft has not met the Traffic Commitment, then, subject to all terms, conditions and limitations in

Confidential

[*]

Page 17

this Agreement, Microsoft shall pay Limelight an amount equal to (i) that amount of the Traffic Commitment not attained as measured in Mbps multiplied by (ii) the weighted average price per Mbps (that is, total invoiced amount in US dollars, or if in another currency, converted into US dollars, divided by the total traffic in Mbps) using the actual traffic volume and invoiced amounts for traffic applicable to the Traffic Commitment [*] to the Traffic Commitment End Date (the “Traffic Commitment Payment”). Microsoft will pay the Traffic Commitment Payment under the terms of Section 5(c)-(e), subject to Limelight’s submission of an invoice, as set forth in Section 5(d).

5. Technical Support Director. To assist Microsoft with meeting its obligations under this section, Limelight shall provide a Senior Technical Support Director, or (at Limelight’s discretion) a more senior person (the “Limelight Technical Support Director”), within [*] of the Effective Date, to assist Microsoft, at Microsoft’s discretion, with facilitating the on-boarding of Services, as defined under the Limelight Content Delivery Service Agreement, to Microsoft properties and assist Microsoft with interacting with Limelight. Each month the Limelight Technical Support Director shall send a report to Microsoft and the Limelight Senior Vice President of Business Development (or such other person(s) as Limelight shall deem appropriate) outlining in reasonable detail the significant aspects of the Parties’ relationship, including, but not limited to, new properties added, properties removed, traffic usage and patterns, SLA concerns, and root case analysis for any problems that arose from the previous month’s service. At Microsoft’s discretion, the Limelight Technical Support Director may reside in an office on the Microsoft campus facility (but, for purposes of clarity, Microsoft is under no obligation to provide the Limelight Technical Support Director an office or other facilities), and if so, then Limelight and the Limelight Technical Support Director shall comply with all obligations related to using such Microsoft office or other facilities, as set forth in this Agreement, the MVG or any other Microsoft policy made available to Limelight.

6. Payment for Services under the Limelight Content Delivery Service Agreement. All payment for Services (as defined under the Limelight Content Delivery Service Agreement) shall be as set forth in the Limelight Content Delivery Service Agreement.

7. PATENT LICENSE

(a) By Microsoft.

1. Microsoft hereby grants to Limelight a personal, nonexclusive, nontransferable, nonsublicensable license under the Licensed Patents in the jurisdictions in which any of the Licensed Patents has issued to make and use the inventions claimed in the Licensed Patents, as limited by the exclusion set forth in Section 7(a)(2) below. “Licensed Patents” means the following patents: [*].

Limelight acknowledges and agrees that as of the Effective Date, none of the services publicly available and offered under [*].

8. PEERING.

(a) Exchange of Traffic. Microsoft and Limelight may exchange TCP/IP data traffic over their respective networks, i.e., Limelight would route its traffic through the [*] ECN Node, and Microsoft would route its traffic (except for traffic under the Limelight Content Delivery Service Agreement) through the Limelight content delivery network. If the Parties so elect to exchange data traffic, then the Parties will set forth in writing the interconnection points for such data traffic exchange (the “Interconnection Points”), and each Party shall provide, at its own expense, connections from its network to the Interconnection Point. Neither Party shall monitor, filter or otherwise restrict the contents of the other Party’s data or traffic as it passes through the Interconnection Points except (i) pursuant to an appropriate confidentiality agreement as necessary for network service or network security, including without limitation to respond to spamming or denial of service attacks, so long as a Party is in compliance with applicable law; (ii) pursuant to the Parties’ respective Acceptable Use Policies; or (iii) in compliance with applicable law or an applicable court order or subpoena. Either Party may monitor control traffic or TCP/IP header and protocol information necessary solely for the operation, problem resolutions and engineering of the Party’s network. The Parties may share this information with each other for such purposes. In no event shall the monitoring Party disclose such information to third parties, except (i) pursuant to an appropriate confidentiality agreement as necessary for network service or network security, including without limitation to respond to spamming or denial of service attacks; or (ii) in compliance with applicable law or an applicable court order or subpoena. Neither Party shall provide to third parties any samples or statistical information derived from the data traffic that passes through the Interconnection Points except (i) pursuant to an appropriate confidentiality agreement as necessary for network service or network security, including without limitation to respond to spamming or denial of service attacks; or (ii) in compliance with applicable law or an applicable court order or subpoena, provided that either Party may collect statistical information derived from the data traffic solely for the purposes of operation, problem resolution and engineering of that Party’s network.

(b) Technical and Operational Matters. If Microsoft and Limelight elect to exchange traffic as set forth in Section 8(a), then the Parties shall work together to establish mutually acceptable performance objectives and operational procedures to enable each Party to provide a high quality service over its network and the Interconnection Points in a cost effective manner.

(c) Pricing. If Microsoft and Limelight elect to exchange traffic as set forth in Section 8(a), then the Parties shall establish in writing the charge for Peer Route Utilization, defined below (provided that, the maximum charge shall be mutually agreed to at the time the exchange of traffic is developed and as modified by the Parties from time to time, using the Burstable Billing calculation method set forth in the Limelight Content Delivery Service Agreement. “Peer Route Utilization” means the amount of traffic delivered for Microsoft on the Limelight content delivery network using Limelight’s settlement-free routes (except for traffic

Confidential

[*]

Page 20

under the Limelight Content Delivery Service Agreement), and similarly, the amount of traffic delivered for Limelight on the [*] ECN Node using Microsoft’s settlement-free routes, provided that (i) the Mbps delivered by the [*] ECN Node will be calculated by measuring the Mbps delivered at each [*] ECN Node location using the Burstable Billing method (as set forth in the Limelight Content Delivery Service Agreement), and then summing the measurements of each location to arrive at a [*] ECN Node total Mbps delivered, (ii) the Mbps delivered on peer routes will be similarly measured at each Limelight content delivery network and [*] ECN Node location, and (iii) the measurement will occur in aggregate across all Microsoft properties. If Microsoft pays Limelight under this section, then such payment shall be paid as set forth in Section 5(c)-(e), subject to Limelight’s submission of an invoice, as set forth in Section 5(d). If Limelight pays Microsoft under this section, then Microsoft shall issue Limelight an invoice for such amount and Limelight shall pay Microsoft the invoiced amount within [*] or, at Microsoft’s discretion, Microsoft may offset any amounts Limelight owes Microsoft under this section against any amounts Microsoft owes to Limelight.

(d) Peering Reports. Limelight shall provide Microsoft (i) a monthly report detailed for each Microsoft property displaying traffic, co-lo, network usage, rack, power, and peering over the Limelight Network, and (ii) a monthly report for Limelight traffic, co-lo, network usage, rack, power, and peering over the [*] ECN Node network. Limelight will reconcile these two reports and provide a document showing the Peer Route Utilization for that month provided for both the [*] ECN Nodes and the Limelight Network.

9. SUBCONTRACTING OF WORK. Limelight shall not subcontract all or any portion of the Services to third parties (each, a “Subcontractor”) without the express prior written consent of Microsoft, which consent shall not be unreasonably withheld.
