	1.	Embarq Complete Contacts Project Description 

 1.1 Product Summary 
 The Embarq Complete Contacts is a repository of addresses originating from
multiple devices including the wire line network, wireless network, webmail and other mail clients. The Embarq Complete Contacts Central Repository will be created and maintained by Fusion One. The purpose for creating Embarq Complete Contacts is to
put all the contact lists that a consumer may have in one location for access by multiple devices. The intent of this initiative is to implement in a phased approach starting with applications that would provide the most value to the Embarq
customers. 
 Synacor is responsible for integrating the Zimbra AJAX webmail client contact list into the Fusion One Embarq Complete Contacts
book and managed by the Embarq IDM. Synacor will utilize the Zimbra Technology to create a network address book Zimlet for the user to perform a self-initiated sync. The primary function of the network address book Zimlet is to sync the webmail
contact list to the Embarq user’s Embarq Complete Contacts. The user initiated sync will exchange contact list modifications, deletions and additions between the Synacor webmail interface and the Fusion One Embarq Complete Contacts book.

 There are several dependencies to this project since Embarq will be collaborating with several other vendors. Synacor will be working
directly with Embarq and Fusion One. 
 1.2 Business Context 
 Embarq has contracted Synacor to be a part of this major integration through agreeing to the terms set forth in the Seventh Addendum to the Contract and approvals for this PRD (Project Requirement
Document). 
 Synacor will only develop this product for the AJAX webmail client. We will not develop this technology for the lite client. Below
you will find a graph with statics to support our decision to only develop this network address book product for the AJAX client.

	2.	Synacor Scope of Work 

 2.1
Project Details 
 The Project Features within this document serve to support the Embarq webmail user, the Fusion One Embarq Complete Contacts
product and the Embarq Management Interface. 
 The features for the Embarq Complete Contacts project to support the Zimbra webmail client will
be developed for the Zimbra 5.0.x release. The Zimlet technology is only available in the AJAX client so Synacor will not be modifying the lite client Embarq skin. Each Zimlet feature Synacor implements will be specifically for the AJAX webmail
client. 
 Synacor provided a testing interface for Embarq’s usability testing on May 19, 2008. This interface resided on the
demo.dev.synacor.com server and simulated the functionality of the following: Load Zimlet, Sync Functionality, and Help hover. 
 R2.1.1
Interfacing with Fusion One – Synacor will be syncing to Fusion One using the SyncML 1.2 protocol. This interface will require Synacor to implement a SyncML 1.2 solution to support Zimbra as an end user device. Synacor will implement an
existing SyncML library and extend upon it for this project. Synacor will use the following: Account Number, PNID#, Device Type, Device ID to identify the user/end point for the sync with Fusion One. 

R2.1.2 Interfacing with Embarq SSO/IDM – Embarq will be hosting the management interface for the Embarq Complete Contacts
System. The Administrative user will designate what sub account will be matched to what Embarq Complete Contact book. There are specific points that we would like to address and are required in order for this project to be successful: 

 

	 	•	 	 Synacor will communicate with Embarq IDM with specific credentials for the end user. Synacor will use the Device ID which will be unique for each user
and the Account Key (Combination of 13-Digit Billing Telephone Number and 10-Digit Working Telephone Number) which is a unique account number. 

  

	 	•	 	 Synacor will receive information from the Embarq IDM system for each myembarq.com user that has the Embarq Complete Contacts feature as part of their
service. Synacor will find out the name of the Embarq Complete Contacts book they have access to. 

 Authentication for Embarq
IDM has been determined and will be further discussed in the TRD (Technical Requirements Documentation). 

  
 Attachment 1 to
Exhibit 16 - Page 5 

 CONFIDENTIAL TREATMENT REQUESTED 

 
 R2.1.3 Network Address Book Zimlet – A Zimlet
allows Synacor to integrate other features into the webmail interface. In this case a Zimlet will allow Synacor to create an interface for performing a sync of the user’s Embarq Complete Contacts within the webmail interface. This Zimlet will
be located in the webmail Address Book toolbar and the webmail WebApps directory on the left side of the webmail interface. Both will launch the Zimlet window. Because this zimlet is being added to the Class of Service of the webmail system it will
be available to all end users. The Name of the Product is “EMBARQ Complete Contacts” and this will be shown as the name of the Zimlet and the name within the title bar of the zimlet. 

If an end user does not have EMBARQ Complete Contacts configured for their account and launches the Zimlet they will be presented with the following
error (proper wording for the error to be determined by Embarq): 
 “Sorry, you are not currently subscribed to this feature. Please click
here to learn more.” All field names, text and error messaging for this project will be approved by Embarq. 
 By selecting “learn
more” the user will be taken to an Embarq landing page in a new browser window that will give them more information about EMBARQ Complete Contacts and its features. This information page will have a sales message for the product and will be
created by Embarq; it will include all of the appropriate Embarq contact information. 
 The Zimlet will display the title bar, a Help Icon,
EMBARQ Complete Contacts Name, Last Sync Date, ‘Manage’ button (to launch Embarq.com interface or the PIM interface for the end user TBD), ‘Sync Now’ button, and a ‘Cancel’ button. The Zimlet will launch from
double-clicking. 
 R2.1.3.1 Zimlet Right Click Functionality (Right click – single click on menu item) 

 

	 	•	 	 Launch – This will open/launch the zimlet window in the webmail interface. 

 

	 	•	 	 Sync Now – This is a one-click option for the user to select and immediately begin syncing. The zimlet window will open on the preparing to
sync screen. 

  

	 	•	 	 Manage Account – This will open a new browser window with Embarq.com if the user is an admin user for embarq.com it will open to their
account (once SSO is established) if they are not an admin user then the appropriate pages will be displayed (Need direction from Embarq) 

  

	 	•	 	 Manage EQ List – This will open a new browser window into the PIM interface (Fusion One) with the user logged on.

 R2.1.3.2 Hot Keys – If the Zimlet is launched and the user hits enter, the ‘Sync Now’ process
will begin.

 R2.1.3.3 Title Bar – This will be the name of the EMBARQ
Complete Contacts Zimlet. This name will also be displayed in the Address Book tool bar and the Webapps directory. 
 R2.1.3.4 Help Icon
“?” – The help icon will open an information dialogue box and will contain basic information EMBARQ Complete Contacts. The dialogue box will open as a hover box when the mouse is over the icon. This help information will be
provided and approved by Embarq. (Suggestion below) 
 Embarq Complete Contacts – This is the name that has been
configured for your personal/private address book through embarq.com 
 Last Sync Date – The date displayed is the
last time you sync’d your webmail contact list to your personal/private address book. 
 Sync Now – To sync
your webmail contacts with your personal/private address book you have to press this button to perform the sync. 
 Customer
Service – please contact Embarq at ###.###.#### if you are having problems syncing your webmail contacts to your personal/private address book. 
 R2.1.3.5 Embarq Complete Contacts – The Embarq Complete Contacts field will display the name of the Embarq Complete Contacts book the user has configured through the Embarq.com
Management Interface. 
 R2.1.3.6 Last Sync Date – This is the date of the last user initiated Sync with Fusion One. There
will be no system initiated sync at anytime for this project, only user initiated. (This information will be displayed in the ISP Account Manager). 
 R2.1.3.7 Manage – This Manage button will launch the Embarq.com interface or the PIM interface for the end user in a separate browser window. Synacor will direct the user to an Embarq
interface and Embarq will determine the status of the user and what to present to them. Embarq will provide to us a URL and any other information that is needed (i.e. a token) 
 R2.1.3.8 Sync Now – (ref. Appendix A and B for more information on flows) This is a manual sync button within the EMBARQ Complete Contacts Zimlet which will allow the user to sync their
Zimbra contact updates to the Fusion One Embarq Complete Contacts Book. The sync button is what will begin the user initiated sync processes for the end user to update the Embarq Complete Contacts Central Repository (hosted by Fusion One). This
feature/action will need to be effectively communicated to the end user through product information and marketing updates so the end user knows in order to sync their webmail contact list to the Embarq Complete Contacts product they must select this
button to complete the action of a manual sync. There are several actions taking place during the “Sync Now” performance, we will be using SyncML to send any additions, modification or deletions to Fusion One. 

When the “Sync Now” button is selected the end user will see an image with the following displayed “Syncing Now” to alert the user
that the system is now connected to Fusion One and syncing their contact list.

	 	•	 	 If this is the first time the user has requested a sync to their Embarq Complete Contacts product Synacor will perform a Slow Sync with Fusion One,
which involves syncing the user’s entire Zimbra address book with the Embarq Complete Contacts. 

  

	 	•	 	 If the user has synced to Embarq Complete Contacts before Synacor has stored the sync date as well as the contact data that was synced within a table
for the Embarq Complete Contacts. Synacor will make a call to Zimbra to produce a list of contacts that currently exists within the webmail interface. Synacor will build a list of contacts that needs to be synced to the Embarq Complete Contacts.
Included in this list are only contacts that have been modified, added or deleted since the last sync. 

 Syncing...
The webmail system will begin syncing the appropriate information to Fusion One. 
 An animated clock image will be displayed next to the
message “Syncing...” so the end user can be aware that the system is currently processing their request for the sync. 
 All of the
data gathered during the “Preparing to sync” session will be built into a SyncML message that will be sent to Fusion One. The proper credentials and authentication will need to be passed in order to establish the connection. As Synacor is
sending information to Fusion One, we are also able to update the Zimbra webmail contact list with any modifications that have been made within the Fusion One Embarq Complete Contacts Central Repository. Fusion one will handle all of the logic to
determine what gets deleted, added, or changed. Once the sync is complete Synacor will save the last sync time and the contact data (IDs) that have been synced. 
 Sync completed successfully. The webmail system will display to the end user that the sync is complete and was successful. 
 R2.1.3.9 Retry button – In case there is a problem with Synacor connecting to Fusion One there will be a Time Out limit set to 30 seconds. 

Upon the first fail we will present a retry button with a message that states “Your Sync has failed. Please try again.” When the user selects
retry, and the sync is not successful but fails again, a second error message will display and the retry button will be removed. The second error message will be “Your sync has failed, we apologize for any inconvenience. Please try again in a
few minutes.” 
 R2.1.3.10 Close – Selecting close will simply close the zimlet and the dialogue box. The user will be
able to access the zimlet at any time from the Address Book toolbar or the WebApps directory. 
 R2.1.4 Email Component or
MyEmbarq.com User Management – Manage Embarq Complete Contacts button will reside within the current MyEmbarq.com email component. This Manage button will be a duplicate of the Manage button within the Zimlet and will launch the
Embarq.com Interface in a separate browser window. This button will only be displayed if the user’s role is HOH. If the user does not have Embarq Complete Contacts associated with their account, this button will link to an information page
providing the user with a sales message for the product. Embarq will create this page.

 R2.1.5 Reporting – Synacor will add sync logging to
an internal reporting mechanism which will keep a detailed error log for Synacor to access at anytime. 
 R2.1.6 Fusion One
Plug-in – Fusion One will be creating a custom-made Plug-In for Embarq. Embarq will provide to their end users that access email through POP an Embarq Complete Contacts plug-in to use with their mail client to sync their contact list.
Synacor will not be integrating this product. We will simply be providing a link to the plug-in in an appropriate area on the portal so POP users can access it. Our recommendation to Embarq is to not advertise this option to their end users. Embarq
and Synacor should be marketing to end-users the benefits of webmail since it is a revenue generating product, and we want more people to use webmail versus POP. 
 R2.1.7 Addition to Portal Directory – Synacor will add a sub menu under “My Account” that states EMBARQ Complete Contacts. This will link to one of the
following: 
  

	 	•	 	 Embarq.com – for management of EMBARQ Complete Contacts 

 

	 	•	 	 PIM interface Login – for the individual that is logged into the portal at the time. 

R2.1.8 Marketing Services – This product will require some promotions, Banners and spotlight ads on the portal at MyEmbarq.com.
These ads will be strictly promotional; they will provide the user with features and benefits of this product along with contact information for customer service. The contact will be for more information or assistance with the product. 

R2.1.9 ISP Account Manager – The ISP Account Manager is a tool provided by Synacor for Embarq Customer Services Teams and
Synacor TSS. It provides all account, email and premium service information per account and per user. We will include in the ISP tool information for each user that has configured for their account an Embarq Complete Contacts product. We will add a
new module labeled “Embarq Services”. For this project the service displayed will be: 
 EMBARQ
Complete Contacts – enabled/disabled 
 Last Sync Date: April 1, 2008 3:45pm
(successful/unsuccessful) 
  

	 	•	 	 Enabled: The end user has Embarq Complete Contacts configured for their user account. 

 

	 	•	 	 Disabled: The end user does not have Embarq Complete Contacts Configured 

 

	 	•	 	 Successful: The end user initiated a sync and there were no communication problems 

 

	 	•	 	 Unsuccessful: The end user initiated a sync and there were some unknown communication problems 

 

	*	If EMBARQ Complete Contacts is deactivated for the account or the end user for any reason the ISP Manager will display “disabled”

 R2.1.10 Support Page – all EMBARQ Complete Contacts
documentation will live on the Embarq.com page. However, the Support Page for MyEmbarq.com will have a EMBARQ Complete Contacts Category. This category will be a link and it will perform one of two actions: 

 

	 	•	 	 Link to the Embarq.com support page 

  

	 	•	 	 Link to the EMBARQ Complete Contacts PDFs – which will be designed and hosted by Embarq. 

R2.1.11 Server Notifications – This section is provided by the Fusion One Integration Guide 

Figure 1. Automatic Sync Initiation by End Point 

The Fusion One Synchronization Platform has the ability to alert end points by sending them notification messages over the network. Such
end points will typically be partner end points but could also be public end points such as mobile phones which can be reached by SMS, or email clients that can be notified by email. Having received such an alert, an end point is expected to
automatically start a synchronization session with the Fusion One NAB service. This mechanism is useful in automatically propagating address book changes from one end point to the rest, but it requires the end point to have the ability to listen for
and receive network notifications and react accordingly. A standard method for doing this – Server Alerted Sync Notification - is provided in the OMA DS specification. However that is a binary format designed for SMS bearers in mind and
therefore may be cumbersome to implement in the internet world. Therefore Fusion One will propose an improved alternative notification protocol specification shortly. 
 R.2.1.11.1 Notification Listener at End Point 
 End Points that will
support server alerted sync notification MUST provide a listener to receive MPB generated sync notifications. In the case of partner end points, the notifications will be transported through the VPN tunnel between Fusion One datacenter and partner.

 R2.1.11.2 Limited Sync Occurrence Scenarios 
 End point MUST NOT initiate a SyncML session based on schedule or any other activity outside of the scenarios listed above. 
 R2.1.11.3 Pre-negotiated Sync Occurrence Scenarios 
 Each End Point vendor
MUST communicate apriori to Fusion One, the sync methods its end point will use. There is no formal End Point certification process but Fusion One MUST have this information in order to appropriately size its system.

 2.2 Performance Requirements 
 This project will not require any additional hardware. This project is made up of a series of database and API calls. Most of the work will be performed in the sync with Fusion One which will consume
minimal resources within Synacor. These resources are within Zimbra which are not connected to the portal. All of the calls are user initiated. 

For all connections to Fusion One our time out limit will be 30 seconds. Each error will be logged within a NAB error log. 

Synacor will determine if there is an issue with the connection and will take the appropriate steps to rectify it and following existing Service Level
Agreements under existing C.O.XX063016TPS, Exhibit 5, Section 6. Synacor will contact the Embarq 24 x 7 Helpdesk at 1-877-726-435. They would open a ticket, assign a priority, and engage Outage Management if the ticket is a Priority 1 or
Priority 2. 
 Embarq and Fusion One will need to ensure Synacor that their web services are always available and that their authentication
credentials will not change, if any change is made or is necessary Synacor is requiring a notification of change 30 days in advance. With this advance notice we will be able to make the necessary changes and make them live within one of our release
windows. 
 EMBARQ Complete Contacts is functional only to subscribed users. Only those customers that subscribe to EMBARQ Complete Contacts,
which could be high speed internet customers or non-high speed internet customers will have access to the EMBARQ Complete Contacts. Of the users that have purchased Embarq Complete Contacts, the only time there will be any heavy performance hit is
when the user decides to initiate sync. The only automatic action that happens is when the Embarq Complete Contacts Zimlet loads. When the Zimlet loads Synacor will be querying the EMBARQ IDM to see if the user has access to Embarq Complete
Contacts. 
 2.3 Quality Requirements 
 This project must meet all of the requirements put forth in this document. The product look and feel must be identical to the mockups. The mockups have been designed by Synacor and will be approved by
Embarq. 
 All features and functions must be unit tested and approved by the Synacor QA department and Embarq as set forth in Section 4.3
of this Attachment 1 to Schedule 16 before this product will be released to live. 
 2.4 Test Requirements 

The Embarq Complete Contacts Zimlet has to work with both Fusion One and with EMBARQ IDM. Testing of the Zimlet will be successful when it syncs the
Zimbra webmail contact list with the Fusion One Embarq Complete Contacts book, as well as the Fusion One Embarq Complete Contacts book with Zimbra webmail again. 

  
 Attachment 1 to

 Two Syncs must be tested: 

 

	 	•	 	 Initial sync (first time use) 

  

	 	•	 	 Subsequent sync (after modifying, deleting, and adding contacts) 

 Synacor will be coding the ability to turn the product “on” or “off”. That means even though we have the ability to use the product on production servers it will not be accessible or
even visible until we are ready to turn it on. 
 For end-to-end testing Synacor will create “special” users for testing that can see
the product but still not have it turned on for all of Embarq. Actions to create “special” users: 
  

	 	•	 	 create an account via user_create API 

  

	 	•	 	 login to Zimbra Admin and add the NAB Zimlet to the specific user account we just created 

2.5 Service Level Requirements 
 The EMBARQ Complete Contacts Zimlet within the webmail interface must always be available to users with EMBARQ Complete Contacts. The Zimlet will not be available to users that are not provisioned for
EMBARQ Complete Contacts via EMBARQ. 
 2.6 Technical Support Services Requirements 

Any Sync errors that occur will need to be logged by Synacor in a NAB error log. The Technical Support Services (TSS) department or an assigned Synacor
employee will have access to these logs if reporting is requested by Embarq. 
 Synacor will require documentation for Escalation Paths and
Processes for Support purposes. Synacor will also need to understand the mode of communication/notification if there is a problem with Fusion One. Synacor will have to be included in any communications regarding problems with Fusion One, IDM, SSO
and Embarq.com (myservices). 
 2.7 Documentation Requirements 

 

	 	•	 	 Fusion One API documentation 

  

	 	•	 	 Synacor SyncML integration documentation 

 2.8 Training Requirements 
 Synacor will use this PRD as well as EMBARQ promotional
materials to familiarize the appropriate departments with the product. 
 2.9 Other Requirements including Metrics and
Analytics. 
 No other requirements that we are aware of at this time.

	3.	Assumptions, Dependencies, Constraints 

 3.1 Assumptions 
 We are assuming that EMBARQ IDM and the Fusion One web services are always
available and that authentication credentials will not change at anytime. If any change is made or is necessary Synacor is requiring a notification of change 30 days in advance. With this advance notice we will be able to make the necessary changes
and make them live within one of our release windows. 
 3.2 Dependencies

EXHIBIT 16 – DEVELOPMENT ADDENDUM 
 Single Sign-On Project Description 
 Section 1. Overview 

 

	 	1.1	Product Summary 

 Provide an
overview of the product. 
 The Single Sign On project with Embarq is intended to sync the usernames between embarq.com and
myembarq.com so customers can seamlessly go between the two sites without having to log in separately. Additionally, this project will link Synacor to the Embarq Identity Management system so we can access additional product information for the
customers, enabling Synacor to allow user access to new products that will be integrated into the myembarq.com portal like EMBARQ Complete Contacts and Integrated Voicemail. 

 

	 	1.2	Business Context 

 Describe the
Business Context or driver for this PRD. 
 ÞThis initiative will provide an
overall better customer experience in addition to enabling Synacor to better be able to target messaging and product information to customers on myembarq.com by knowing more about the customer and what products they already have. With this ability
to do more direct targeting the parties are expecting a higher cross-sell capability through myembarq.com. 
 Section 2.
Synacor Scope of Work 
  

	 	2.1.	Username syncing 

 Synacor will
be changing the Username Management and registration processes for Embarq so that when a username is added or deleted that it makes an API call to Embarq’s IDM to add or remove that email address. Additionally since Embarq keeps track of the
customer’s first and last name, if those values are changed in Username Management, an API call will be initiated to Embarq’s IDM to update the first or last name. 

 

	 	2.2.	Change the inactive username deletion script to call Embarq IDM 

 The current script that deactivates users after 6 months of being suspended will be updated to call Embarq’s IDM via API to also remove the email address being deleted from IDM. 

  
 Attachment 1 to
Exhibit 16 - Page 19 

 CONFIDENTIAL TREATMENT REQUESTED 

 
  

	 	2.3.	Change the logged in links to all the EQ apps 

 Every Embarq.com application that will require SSO must go through an SSO redirect script that is created in 2.5. In a logged out state, the links on the portal to these applications should go to the
application itself. In a logged in state, the links should all go through the SSO redirect script. 
  

	 	2.4.	Create login page for linking process 

 Synacor is creating a login page with the look and feel of Embarq’s username linking application that will be used in the middle of the linking flow. After a customer logs in with an EQ.com username
and password and attempts to traverse to the portal, they are sent into the linking flow provided that the username is not already linked to a portal,. To link an account it sends the customer to this login page, which will have an email address and
password prompt. There are also 3 buttons: Login, Not now, and Never link. The Login button will submit the login form and validate the credentials. If successful, the user is redirected back to EQ.com in the linking application with some
signed/encrypted GET parameters validating that the authentication succeeded and giving the EQ.com linking flow the email address that was logged in. If the customer clicks “Not now”, the customer is sent back to the linking flow and
eventually to the portal logged out. If the customer clicks “Never Link”, the customer is sent back to the linking flow and eventually to the portal logged out. Such user should not see the linking flow again. 

 

	 	2.5.	SSO redirect for EMBARQ.com applications 

 Synacor creates a redirect script or “exit page” for leaving the myembarq.com site and traveling to an Embarq.com application in a logged in state. This redirect should only be used by logged in
users. If the user is not logged in, it will send them to the login page for MyEmbarq with a bounce to link back to the redirect script so that after login the customer will be sent directly to the EQ.com application. 

 

	 	2.6.	Add SSO landing page for traveling to MyEMBARQ from EMBARQ.com 

 Synacor will build an “entrance page” for the portal so that users traveling from an Embarq.com application in a logged in state get dropped off at this page. This page will log in the customer
and send them to the portal.

Exhibit 16 - Page 20 

 CONFIDENTIAL TREATMENT REQUESTED 

 
  

	 	2.7.	Account number changes in admin tool need to call, delete, and create API calls 

 Synacor will change the Admin tool that we have for MyEmbarq.com customers so that changing a customer’s account number calls Embarq’s IDM via 2 API calls (call to delete user, call to add
user). 
  

	 	2.8.	Change parental controls to call “UpdateMyEQIdentity” API when permission scope is changed 

Synacor will change the parental controls section so that changing a customer’s admin / non admin status calls Embarq’s IDM via
API call.
