operational responsibility, comply with Synacor’s reasonable standards, methodologies and procedures. So long as the above activities are within the scope of the Roadmaps [*], they shall be provided by Synacor at no additional charge to
AT&T. 
 Section 1.7.    Notice by Synacor.  Synacor shall promptly notify AT&T
when it becomes aware that an act or omission of an AT&T Third Party provider will cause, or has caused, a problem or delay in providing the Services or operating the Portal that causes, or is likely to cause, a significant customer impact, and
shall work with AT&T, the AT&T Agents and such Third Party providers to prevent or circumvent such problem or delay. Synacor shall cooperate with AT&T, the AT&T Agents and AT&T’s Third Party providers to resolve

Portal Teams first will test the proposed integration, removal, or change, as the case may be, within a small sampling of Users and, if such testing suggests that the Minimum Business Model Requirements and the Minimum Guarantee Requirements, if
applicable, will be maintained after implementation, Synacor will proceed with such implementation. If, after implementation and despite such testing, it is determined that the implementation does not adhere to the Minimum Business Model
Requirements and the Minimum Guarantee Requirements, if applicable, then Synacor may remove the implementation and the Parties may direct the Portal Teams to test alternate methods for such implementation in

Authority. Interest and penalties imposed with regard to Taxes shall be borne by the Party who bears the Tax. 

(b)      Withholding Obligations. If a Party making any payment (the
“Payer”) under this Agreement is required by law to withhold tax (“Withholding Tax”) from any gross payment to the recipient of such payment (“Recipient”) under this Agreement,
Payer shall be entitled to withhold or deduct such tax from the gross amount to be paid. However, Payer shall use all commercially reasonable endeavors to reduce any such Withholding Tax payable to the lowest possible rate subject to compliance
with all applicable Laws and double taxation treaties. Upon request by Recipient, the Payer will in the case of any withholding of tax provide to the Recipient reasonable evidence that such Withholding Tax has been paid. 

(c)      Cooperation. The Parties shall cooperate with each other to
assist each Party to determine accurately its respective Tax liabilities and to reduce such liabilities to the extent legally permissible. To the extent required, each Party shall provide to the other any valid resale certificates, valid

Section 8.9.         Additional Agreements Concerning Economics. 

(a)      The Parties shall cooperate and work together to increase the revenue

sources of revenue and any new sources of revenue from traffic and Searches on the Portal, the Portal Toolbar, and the AT&T Properties, on a regular basis, but no less frequently than quarterly. 

(b)      The Parties agree to discuss the potential use of certain Synacor
functionalities and capabilities (e.g., insight based on big data integrations, cross website campaign optimization, and other functionalities) through a Link or display/video promotion on the Portal that will enable the sale of certain
AT&T subscription services (e.g., DIRECTV, U-verse television, HSIA, or AT&T Mobility). If the Parties agree to use such Synacor services in connection with the Portal, then the Parties will negotiate an amendment to this
Agreement with respect to such services.

(iii)    For each [*] commencing [*] and thereafter, Synacor shall be entitled to [*]. 

The $[*] amounts in clause (b) above are referred to as the “Minimum Payment Amounts.” 

(c)       If, during any [*] the total Synacor Revenue Share for such
payment period does not equal or exceed the applicable Minimum Payment Amount for such period, then for such [*] Synacor will retain as much of the AT&T Revenue Share collected by Synacor as necessary for Synacor to receive the applicable
Minimum Payment Amount for such [*] (any such amount, a “Retained Amount”). If, in any [*], Synacor receives insufficient Display Gross Revenue and Net Search Revenue to receive the full Minimum Payment
Amount, the deficit will be carried over into subsequent [*] until such time as Synacor has received the full amount of all Minimum Payment Amounts owed to it. 

(d)       At the end of each calendar year, Synacor shall calculate (i) the
amount, if any, by which the total Synacor Revenue Share for such year [*] exceeds the aggregate Minimum Payment Amounts for such year [*] (any such amount, the “Excess Amount”) and (ii) the total Retained Amounts for
such year [*]. Within [*] Synacor will reimburse AT&T for the Retained Amounts up to, and to the extent of, any Excess Amount. If, instead, there is a Minimum Payment Amount deficit at the end of the Initial Term or Renewal Term,

Synacor shall promptly destroy any copies of such AT&T Data and AT&T Derived Data in Synacor’s possession or under Synacor’s control unless such AT&T Data or AT&T Derived Data is required for Synacor to perform the Services
or is otherwise permitted under Exhibit 24, in which case Synacor promptly will destroy the AT&T Data or AT&T Derived Data when it is no longer required by Synacor to perform the Services or exercise its rights under Exhibit
24. Upon AT&T’s request Synacor shall deliver to AT&T written certification of such return or destruction signed by an officer of Synacor. Synacor’s obligation to return AT&T Data and AT&T Derived Data upon AT&T

 Section 18.8.    Procedures for
Indemnification. 
 (a)      If any Third Party claim is commenced against
either Party for which either Party is entitled to indemnification under Section 18.6, notice thereof shall be given to the Indemnifying Party as promptly as practicable. The Indemnifying Party will, except as provided in this paragraph,
assume the defense of such claim, with counsel reasonably satisfactory to the Indemnified Party to represent the Indemnified Party and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, the
Indemnified Party shall have the right to retain its own counsel, at its own expense, unless the Parties shall have mutually agreed to the retention of such counsel. The Indemnified Party shall have the right to control the defense of such
claim if (i) the named parties to any such proceeding (including any impleaded parties) include both the Indemnified Party and the Indemnifying Party and representation of both Parties by the same counsel would be inappropriate due to actual or
potential differing interests between them, or (ii) the Indemnifying Party refuses or fails to timely assume the defense of such claim. 

(b)      The Indemnifying Party shall not be liable for the settlement of any proceeding
affected without its written consent. The Indemnifying Party shall not, without the prior written consent of the Indemnified Party, effect any settlement of any pending or threatened proceeding (i) if such settlement involves any finding or
admission of the Indemnified Party of any violation of any law, regulation or order or any of the rights of any person or has any adverse effect on any other claims that have been or may be made against the Indemnified Party, (ii) if such settlement
imposes any material obligation on the Indemnified Party, or (iii) if such settlement involves the payment of money, unless it includes an unconditional release of the Indemnified Party of all liability on claims that are the subject of such
proceeding. 
 (c)      The Indemnifying Party shall have no obligation for any claim under
this Section if: (i) the Indemnified Party fails to notify the Indemnifying Party of such claim as provided above, but only to the extent that the defense of such claim is prejudiced by such failure; (ii) the Indemnified Party fails to tender
control of the defense of such claim to the Indemnifying Party as provided in Section 18.8(a); or (iii) the Indemnified Party fails to provide the Indemnifying Party with all reasonable cooperation in the defense of such claim (the cost
thereof to be borne by the Indemnifying Party). 
 Section 18.9.    Election of Remedy. If
the ability of the Indemnified Party to exercise its rights or fulfill its obligations under this Agreement is enjoined or likely to be limited due to a Claim covered by any of the Intellectual Property Rights infringement indemnity obligations set
forth in Section 18.6 (specifically, Section 18.6(a)(i) and Section 18.6(b)(i)), then the Indemnifying Party shall, at its option and expense, exercise commercially efforts to do any of the following: 

(a)      procure for the Indemnified Party the right to use (as provided in this Agreement) the
AT&T Accused Elements (if AT&T is the Indemnifying Party) or Synacor Accused Elements (if Synacor is the Indemnifying Party) that are subject of the indemnification obligation under this Agreement (the “Indemnified
Materials”); 

  
  

 79
 

 CONFIDENTIAL TREATMENT REQUESTED 

 

 (b)     replace the Indemnified Materials with
non-infringing Materials, products or services with features and functions that are substantially similar to, and that do not otherwise materially adversely differ from, the Indemnified Materials; or 

(c)     modify the Indemnified Materials so that they are non-infringing while retaining features and
functions that are functionally equivalent to, and without materially adversely affecting, the Indemnified Materials. 

Section 18.10. Accused Elements Remedies. If an Indemnifying Party is unable to provide such modified or
replacement non-infringing Synacor Accused Elements (if Synacor is the Indemnifying Party) or AT&T Accused Elements (if AT&T is the Indemnifying Party) in accordance with Section 18.9, the Indemnified Party shall have the
right, at its option and without prejudice to any other rights or remedies that it has in contract, law or equity [*]. 

Section 18.11. [*].

Section 18.12. Exclusions. The Indemnifying Party will have no obligation under the applicable provisions of
Section 18.6 (specifically, Section 18.6(a)(i) and Section 18.6(b)(i)), with respect to Claims alleging infringement of a Third Party’s Intellectual Property Rights to the extent that such Claim is based on or arises from:

 (a)     any Advertisements, Content, or Materials created, developed, licensed, or otherwise
provided by the Indemnified Party or any of the Indemnified Party’s Affiliates or Agents; 

(b)     any use, reproduction or distribution of the Indemnified Materials by the Indemnified Party
in violation of any material term set forth in this Agreement; 
 (c)     any use of the Synacor
Accused Elements or AT&T Accused Elements, as the case may be, by the Indemnified Party in combination with other products, equipment, software, or data not supplied by the Indemnifying Party hereunder (excluding any combination that is
foreseeable in light of the nature of the Services or inherently required to permit AT&T to make full and proper use of the Synacor Accused Elements or Synacor to make full and proper use of the AT&T Accused Elements, as applicable); or 

(d)     any unauthorized modification or alteration of the Indemnified Materials by the Indemnified
Party.

 Section 18.13. Allocation. 

(a)     If a Claim is based partially on an indemnified Claim described in Section 18.6
(subject to Section 18.12) and partially on a non-indemnified claim, or is based partially on a Claim indemnified by one Party and partially on a Claim indemnified by the other Party pursuant to Section 18.6 (subject to
Section 18.12) (a “Combination Claim”), each Party shall be liable to pay only its Proportionate Share of the Losses associated with such Combination Claim. The “Proportionate Share”
payable shall be a portion of the Losses determined on an objectively fair and equitable basis to be attributable to each Party based on the degree of cause attributable to such Party in the Combination Claim. The Proportionate Share of each Party
shall be determined, insofar as possible, through good faith negotiation between the Parties; provided, however, that a failure of the Parties to agree on either Party’s Proportionate Share shall not relieve such Party of its obligations to pay
its Proportionate Share under this Section. Each Party shall make payments in satisfaction of its Proportionate Share obligation whenever such payments become due. 

(b)     Any judgments, payments and reasonable attorneys’ and experts’ fees incurred in
connection with such Combination Claims are to be apportioned between the Parties in accordance with the degree of cause attributable to each Party determined in the lawsuit resolving the Combination Claim (or claim, if not an indemnified claim),
or, if not so determined, pursuant to Section 20.4; provided, however, that in such instance each Party shall participate in the defense of such Combination Claim and the cost of such defense shall be apportioned between the Parties in
accordance with the determination of the lawsuit involving the Combination Claim or, if not so determined, pursuant to Section 20.4.

Agreement shall be finally settled pursuant to the Commercial Arbitration Rules and Mediation Procedures of the American Arbitration Association (AAA) by one or more arbitrators appointed in accordance with such rules; provided, however that all of
such independent arbitrators shall be experienced in and knowledgeable about the information technology, Internet, Advertising and telecommunications industries. 

(b)      Governing Law. The applicable law shall be that of the State of New York
without regard to its conflict of laws rules. The place of arbitration shall be New York, New York.

applicable Law. Subject to the exercise by a Party of any appeal right it may have under applicable Law, judgment on the award rendered by the arbitrators may be entered in any court having competent jurisdiction. The arbitrators may hear and

of the foregoing shall be null and void ab initio. 
 Section 21.4.    Governing Law;
Jurisdiction.

Party irrevocably waives, to the fullest extent it may effectively do so, any objection that it may now or hereafter have to the exercise of personal jurisdiction by the U.S. District Court for the Southern District of New York or by any New York

disclosure and comply with any protective order imposed on such disclosure. If either Party determines that it is required by applicable Laws, rules or listing agreements to file or otherwise disclose this Agreement or any provisions hereof, that

to Section 21.5(c), the Receiving Party shall at all times, both during the Term and thereafter: (i) hold the Disclosing Party’s Confidential Information in confidence and take all reasonable measures to maintain the confidentiality of

its Affiliates’ employees, representatives, agents or independent contractors with a demonstrated “need to know” such information and only to the extent necessary or reasonably appropriate to permit the Receiving Party to exercise its

which are substantially similar to the confidentiality obligations set forth in this Agreement; and (iii) use such Confidential Information only for the purposes for which it was disclosed and as may be reasonably necessary for the performance of

disclosure. The Receiving Party shall disclose only such information as is required, in the opinion of its counsel, and shall use commercially reasonable efforts, at the expense of the Disclosing Party, to obtain confidential treatment for any

the case of a waiver, by the Party against whom the waiver is to be effective and such amendment or waiver identifies the specific sections contained herein which are to be amended or waived. No
failure or delay by either Party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. 
 Section 21.11. Counterparts; Effectiveness. This Agreement may be executed in any
number of counterparts, each of which shall be deemed an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective when each Party has received counterparts hereof
signed by the other Party. 
 Section 21.12. Interpretation. The following principles of interpretation and
construction apply to this Agreement and all attached Exhibits, annexes and schedules to this Agreement, unless otherwise expressly indicated or required by the context. 

(a)    Any capitalized term used in this Agreement that is not defined herein shall have the generally
accepted industry or technical meaning given to such term. 
 (b)    The recitals and article and
section headings contained in this Agreement are included for convenience of reference only and shall be ignored in the construction or interpretation hereof. The Parties acknowledge that this Agreement has been drafted jointly by the Parties hereto
and agree that this Agreement shall not be construed against either Party as a result of any role such Party may have had in the drafting process. 

(c)    The Parties acknowledge that the provisions of this Agreement were negotiated to reflect an
informed, voluntary allocation between the Parties of all risks (both known and unknown) associated with the transactions contemplated by this Agreement. 

(d)    References in this Agreement to, and the definition of, any document or Exhibit shall be deemed a
reference to such document or Exhibit as it may be amended, supplemented, revised, or modified, in writing, from time to time but disregarding any amendment, supplement, replacement or novation made in breach of this Agreement. 

(e)    Unless otherwise provided to the contrary, (i) all references to days, months, quarters or years
shall be deemed references to calendar days, months, quarters or years, (ii) any reference to a “Section,” “Article,” “Exhibit” or “Schedule” shall be deemed to refer to a section or article of the document
containing the reference or an exhibit or schedule to the document containing the reference, (iii) any reference to an Article shall be deemed to include all Sections and subsections contained in such Article, any reference to a Section or
subsection shall be deemed to include all subsections and paragraphs of such Section or subsection, and any references to an Exhibit shall be deemed to include all Schedules of such Exhibit, (iv) any reference to a Law shall be deemed to include any
amendment, modification, re-designation or extension to such Law and any rules or regulations promulgated thereunder or any Law enacted in substitution or replacement therefor, and (v) any reference in this Agreement to a time of day means the time

 CONFIDENTIAL TREATMENT REQUESTED 

 

 (f)    Unless the context requires otherwise, words
importing the singular include the plural and vice versa and words importing gender include all genders. The terms “including,” “include” and “includes” will be deemed to mean “including without limitation”
and “including but not limited to” (or “includes without limitation” and “includes but is not limited to”) regardless of whether the words “without limitation” or “but not limited to” actually follow
the term. The words “hereby,” “hereof,” “herein” and “hereunder” and words of similar import referring to the document containing such words refer to the entire document in which they are contained and not to
any particular provision of such document. Whenever the word “or” is used in this Agreement, it will be deemed not to be exclusive. Whenever the word “discretion” is used with respect to a Party, it will be deemed to mean such
Party’s sole discretion, regardless of whether it is reasonable, unless otherwise expressly stated elsewhere in this Agreement. When there is similar, but not identical, construction of phrases, sentences, or clauses of this Agreement, no
implication is made that a “negative pregnant” is intended, and they will each be construed separately, in accordance with their plain meaning. Unless otherwise specified, references to “$” or “dollars” will be deemed a
reference to United States dollars, and all accounting terms, ratios and measurements will be interpreted or determined in accordance with United States GAAP as in effect as of the date of measurement. The words “shall” and
“will” are used interchangeably and both mean the specified action or forbearance is mandatory. The words “can” and “may” are used interchangeably and both mean that the specified action or forbearance is permitted.

 Section 21.13. Severability. The provisions of this Agreement shall be deemed severable and the invalidity or
unenforceability of any provision or part thereof shall not affect the validity or enforceability of any other provision hereof. To the extent permitted by applicable Law, the Parties waive any provision of Law which renders any provision of this
Agreement invalid or unenforceable in any respect. To the fullest extent permitted by Law, if any provision of this Agreement, or the application thereof to any Person or circumstance, is invalid or unenforceable: (a) the Parties shall engage in
good faith negotiations to replace any provision which is declared invalid or unenforceable with a valid and enforceable provision, the effect of which comes as close as possible to that of the invalid or unenforceable provision which it replaces;
and (b) the remainder of this Agreement shall not be affected by such invalidity or unenforceability. 
 Section 21.14.
Interim Relief. It is expressly agreed that a breach by a Party of the applicable license grants herein or Article XVI, an infringement by a Party of the Intellectual Property Rights of the other Party, or a breach by a Party of
Section 21.5 may cause irreparable harm to the other Party which harm cannot be adequately compensated in damages. It is also expressly agreed that a failure by Synacor to deliver Wind-Down Assistance or deliver any AT&T Data to AT&T
upon expiration or termination of this Agreement may cause irreparable harm to AT&T which harm cannot be adequately compensated in damages. Each Party acknowledges that any of the aforementioned breaches (whether actual, attempted or threatened)
would be immediately and irreparably harmful to the other Party and monetary compensation would not be measurable or adequate. Therefore, in addition to any and all remedies available at law, and notwithstanding Section 20.5, a Party shall be
entitled to seek an interim injunction or other equitable remedies in a court of competent jurisdiction, without the necessity of posting bond, upon any threatened or actual breach of any or all of the above provisions or infringement.

 Section 21.15. Remedies Cumulative. Unless expressly provided
otherwise herein: (a) all rights and remedies granted to each Party under this Agreement are cumulative and in addition to, and not in lieu of, any other rights or remedies otherwise available to such Party in this Agreement, at law or in equity;
and (b) termination or expiration of this Agreement shall not limit either Party from pursuing any other remedies available to it, including injunctive relief, in connection with any of its rights accrued or otherwise existing up to the date of such
termination or expiration. 
 Section 21.16. Business Continuity and Disaster Recovery Plan. During the Term and
the Wind-Down Period, Synacor shall maintain, update and comply with the disaster recovery plan (the “DRP”) set forth on Exhibit 28 (Business Continuity Services and Disaster Recovery Plans), [*]. 

Section 21.17. Force Majeure. 

(a)    Neither Party shall be liable for any default or delay in the performance of its obligations
hereunder to the extent, and while, such default or delay is caused by a Force Majeure Event. 

(b)    If a Force Majeure Event occurs, the nonperforming Party shall be excused from any further
performance or observance of the obligations so affected for as long as such circumstances prevail and such Party continues to use commercially reasonable efforts to recommence performance or observance whenever and to whatever extent possible
without delay. A Party so delayed in its performance shall immediately notify the other Party by telephone and describe at a reasonable level of detail the circumstances causing such delay (to be confirmed in writing within twenty four
(24) hours after the inception of such delay). 
 (c)    [*]: 

(i)      [*]; or 

(ii)      substantially prevents or delays performance of the Services for more
than [*] AT&T may terminate the affected Services as of a date

(d)    [*]. 

(e)    Allocation of Resources. Except where required by Law, whenever a Force Majeure Event
causes Synacor to allocate limited resources between or among Synacor’s customers, Synacor shall not intentionally provide to any other customers of Synacor priority over AT&T. 

Section 21.18. Export Controls. Each of the Parties shall comply fully with all relevant export laws
and regulations of the United States to ensure that no information or technical data provided pursuant to this Agreement is exported or re-exported directly or indirectly by such Party in violation of applicable Law. 

Section 21.19. Relationship of Parties. Each of the Parties is an independent contractor and shall have no right, power
or authority to assume or create any obligation or responsibility on behalf of the other. This Agreement shall not create or imply, or be construed to create or imply, any partnership, association, agency, fiduciary relationship, joint venture or
joint or several liability between the Parties. All employees of each Party performing responsibilities under this Agreement, whether such responsibilities are performed on the premises of the other Party, shall be considered for all purposes of
this Agreement employees of such employing Party. As between the Parties, personnel on the payroll of a Party shall be deemed to be employees of that Party, regardless of any other characterization by a court or administrative agency or the location
at which they perform obligations pursuant to this Agreement. As between the Parties, Synacor and AT&T respectively shall each be solely liable with respect to each of its own employees for all aspects of the employer-employee relationship, to
the extent such conduct may result in employer liability.

 Introduction 

This document describes the AT&T Identity Provider (IDP) standard federation integration steps. Any federated Service Provider (SP) planning to integrate
with AT&T IDP shall first review this document to understand the current supported federation model. SP integration requirements not satisfied by this model shall be viewed as non-standard federation requirements and may entail additional work
effort. Federated partners may consider implementing standard federation first and then initiate enhancements to that implementation to support non-standard requirements. 

Federation Metadata 
 Any federation agreement between AT&T IDP
and partner SP shall require the mutual exchange of metadata to support the configuration of IDP and SP end points. This exchange must take place over secure communication channel where integrity of the exchanged data can be asserted (for example
through digitally signed emails). 
  

	 	●	 	The federation agreement shall use SAML 2.0 protocol for authentication/authorization request/response exchange 

	 	●	 	For authentication flow, Web Browser SSO Profile shall be utilized with HTTP POST Binding 

	 	●	 	All the communication end points between AT&T IDP and partner SP must be HTTPS 

	 	●	 	Only persistent nameid format is currently supported for Opaque Identifier (OID) generation 

	 	●	 	Self signed certificates are not supported in authN/authZ request/response exchange. Additionally, AT&T reserves the right to reject the CA authority used by service provider for SP certificates consumed on AT&T
server endpoints (certificate used for digitally signing the SAML request or client certificate used during authorization request). 

              Note: AT&T Supported CA
Authorities 

	 	¡ 	 	 Verisign, Entrust, GeoTrust, Thawte

 Federated Authentication 

AT&T currently supports two transaction federated authN/authZ model. In this model the first transaction is utilized for user authentication and
subsequent transaction happens directly between the partner SP and IDP for user authorization. This section provides the details of user authentication flow. 

Authentication Flow Diagram 
  

 
 Fig 1: User Authentication Flow Diagram 

Authentication Request Processing 
 The federated authentication
SAML request may be initiated through user accessing the partner hosted entitled web content. Upon access request partner SP shall initiate the HTTP POST of SAML authentication request, through user HTTP client, to AT&T supplied
SingleSignOnService URL endpoint. 
  

	 	●	 	 For message integrity purpose, partner SP MUST sign the SAML authN request. 

	 	●	 	 The SAML request must be first BASE64 then URL encoded in the HTTP POST request. 

	 	●	 	 SP may also send the relay state as part of the form POST body. AT&T IDP shall return the relay state
parameter value while sending a SAML assertion back to service provider. 

	 	o	 AT&T IDP requires two consecutive relay state values to be different from each other.

 e.g. RelayState=https://www.sp.com/resource.html?random=1 | 

https://www.sp.com/resource.html?random=2

 ●    AT&T IDP shall present a common default login page to
federated customers for authentication purpose. 
 ●    As part of authN flow, due to multiple unsuccessful
authentication attempts, customer userID may be locked as per internal AT&T CSO lockout requirements. In such condition an error is presented on the login page with appropriate lockout error message and the customer is not redirected back to SP
URL endpoint.

 Authentication Response Processing 

Upon receipt of SAML authentication request, AT&T shall present the login page and authenticate the user through uid/password credentials. After
successful credentials verification a SAML assertion shall be generated and POSTed, through user HTTP client, to partner SP supplied AssertionConsumerService URL endpoint. 
  

	●	 	AT&T currently only supports inline display of the login page. If pop-up page is preferred, partner SP shall control the opening and closing events of the pop-up window (since the authN transaction will initiate
from and terminate at the SP communication endpoints). 

	●	 	AT&T must sign the SAML assertion before sending it to partner SP. 

	●	 	The signature algorithm utilized shall be xmldsig#rsa-sha1. 

	●	 	The canonicalization/transform algorithm utilized shall be xml-exc-c14n#. 

	●	 	If no user opaque identifier exists at this step, a new identifier shall be created and persisted in AT&T DB. Else the existing opaque identifier shall be utilized for SAML assertion generation. 

	•	 	After successful authentication and assertion consumption, partner SP may elect to create a long term SP session such that frequent user re-authentication is not required. This session duration may be governed by
contractual business agreement between AT&T and SP.

 Available AttributeStatement Elements 

UVerse ID Type and Uverse Primary Account OID 
 If warranted by the
requirements, AT&T can optionally provide the authenticated ID type (primary or sub account) and primary ID opaque identifier in the AttributeStatement of the SAML assertion. The attribute element names in the statement shall be
‘IDType’ and ‘PrimaryOID’ respectively. The below table identifies various use cases of IDType and PrimaryOID value combinations: 
  

					
	
IDType
	  	PrimaryOID	  	
Conclusion
  

	
PrimaryAccount
	  	 TG_NOT_FOUND

(no OID value found)
	  	 User has logged in first time with
their Primary Account
  

	
PrimaryAccount
	  	<OID>	  	 User has previously logged in with
their primary account
  

	
SubAccount
	  	 TG_NOT_FOUND

(no OID value found)
	  	 The corresponding primary account
has not logged in yet
 for this federation partner

 

	
SubAccount
	  	<OID>	  	 The corresponding primary account
has logged in before for this federation partner and <OID> represents its opaque identifier
  

 IPTV Subscription 
 AT&T will
provide an indicator if the authenticated user ID has IPTV subscription. This indicator may be used by content providers to support a promotional period for unsubscribed IPTV customers. The attribute element name/value pair in the AttributeStatement
shall be ‘IPTVSubscription=<Yes|No>’. 
 When ‘IPTVSubscription=No’ is returned in the authentication response assertion by
AT&T IDP, service provider shall not send the subsequent authorization request to AT&T authZ URL endpoint since the response to that authZ request will always be ‘Deny’. 

Customer ZipCode 
 This attribute in the AttributeStatement
(attribute name ‘ZipCode’) is available to Service Providers on demand and includes the value of the UVerse customer service address zipcode. 

  
  

Page 10 of 26     

 

 
  

 Authenticated User Identity and Designated mainCTN/subID 

In some scenarios the SP may have a need to know the user authenticated ID and any corresponding CTN/subID linked to that userID (if userID is accessID). The
following three AttributeStatement elements provide the corresponding details in the authN assertion. 

	 	●	 	 userID: authenticated userID 

	 	●	 	 userCTN: user CTN if available 

	 	●	 	 subID: corresponding subscriber ID for the above CTN value 

The following table describes various use cases applicable to these attribute values 

 

							
	Use Case	  	userID element    
value    	  	userCTN element value	  	subID element
value
	User authenticated with accessID and that accessID does not have any designated mainCTN	  	User supplied accessID	  	TG_NOT_FOUND	  	TG_NOT_FOUND
	User authenticated with accessID and the accessID has linked designated mainCTN	  	User supplied accessID	  	Designated mainCTN value	  	Corresponding subID value of the designated mainCTN
	User authenticated with CTN	  	mob_user	  	User supplied CTN value	  	Corresponding subID of the CTN
	User authenticated with any other ID type (Uverse, DSL/Dial, OPR etc)	  	User supplied ID	  	TG_NOT_FOUND	  	TG_NOT_FOUND

 Federated Authorization 

Upon successful user authentication and SAML authN assertion, the Service Provider can initiate a JSON based federation authZ request to
AT&T federation authorization endpoint. This authZ request/response exchange can be used to determine if the authenticated user has access to certain AT&T UVerse service, package or a specific channel. The below section provides the details
of this request/response exchange. 
 Note: This request/response exchange must happen over 2-way SSL protected network path (client
certificate authentication required). 
 Authorization URL Endpoints 

Test/Stage Environment:      https://loginc.stage.att.net/Authz/fedATS/FedAuthz 

Production Environment:      https://loginprodxc.att.net/Authz/fedATS/FedAuthz 

Sample JSON Request/Response Exchange 
 Request 

The Service Provider can submit a HTTP POST request with content-type of application/json and with one of the following JSON object in the
request: 
 {“TG_OP”:“Authorize”,“OID”:“opaqueID”,“CPID”:[“resourceID1”]} 

Or 

{“TG_OP”:“Authorize”,“OID”:“opaqueID”,“CPID”:“resourceID1”} 

Or 

{“TG_OP”:“Authorize”,“OID”:“opaqueID”,“CPID”:[“resourceID1”,“resourceID2”]} 

Here: 
 TG_OP (Required) = operation
name. Currently only ‘Authorize’ operation will be supported 
 OID (Required) = user’s federated opaqueID to be
authorized 
 CPID (Required) = Content Provider ID or resourceID or partnerID 

  
  

Page 12 of 26     

 

 
  

 Response 
 In
response, AT&T may return one of the follow JSON data object. 
 {“OID”:“opaqueID”,“resourceID1”:“Permit”} 

Or 

{“OID”:“opaqueID”,“resourceID1”:“Deny”} 

Or 

{“OID”:“opaqueID”,“resourceID1”:“Permit”,“resourceID2”:“Deny”} 

Or 

{“errorCode”:“<errorCode>”,“errorDescription”:“<error message>”} 

Here: 
 OID = user’s federated
opaqueID (from the request) 
 resourceID1= CPID value supplied by SP in authorization request with the value of either Permit or
Deny. 
 errorCode/errorMessage = if an error happened in processing the request (for instance if any of the required parameters were
missing in the request). For a list of current errorCode please see the next section.

 Federation Authorization Response Error Codes 

Along with ‘Permit’ or ‘Deny’ authorization response described in previous section, AT&T federation authorization endpoint may return
additional authorization failure error codes based on the failure condition. The below table identifies the corresponding error codes and the condition in which these codes will be returned. 

 

					
	      Error Code        	  	Error Message	  	Error Description
	900	  	Internal Processing Error	  	A processing error happened within the system and the client may resubmit the request
	902	  	Invalid Request	  	Received HTTP request is invalid (doesn’t not meet tGuard IA standards)

 Frequently Asked Questions 

Q: Can service provider use the same key pair / certificate for SAML request signing and as the client cert in 2-way SSL for authorization
request? 
 A: Yes. 
 Q: Are
the AttributeStatement elements defined in ‘Additional AuthN Assertion Elements’ available to all Service Providers by default? 

A: No, these elements are available on-demand and need to be requested during the on-boarding request.

 Appendix 
 AT&T
Security Concern and Requirement for iOS UIWebView Authentication 
  
 

 
 The above video outlines our concern with the iOS web view. Usually only an application developer can do this so from that
perspective, the risk is limited. However that does not negate the fact that AT&T and Service/Content provider could become liable for fraud if a developer at a partner company decides to mine MVPD passwords. Currently AT&T is pursuing an
escalation at Apple via the CSO chain of command but until Apple provides review and direction, AT&T is requiring following flow in the log-in process on partner apps. Below is what AT&T is proposing: 

Please find the requirements for content partners implementing AT&T authentication in a iOS UIWebView below: 

	 	1.	 Application shall not monitor activity on any AT&T property (i.e. att.com, att.net domain)

 Objective-C Code Sample that illustrates logic required to implement: 

NSString *currentHost = currentURL = webView.request.URL.host; 

if(currentHost != NULL) 

{ 

NSRange rangeOfAttCom = [currentHost rangeOfString:@“att.com”]; 

NSRange rangeOfAttNet = [currentHost rangeOfString:@“att.net”]; 

if((rangeOfAttCom.location == NSNotFound) && (rangeOfAttNet.location == NSNotFound)) 

{ 

// not an AT&T page, do any of your processing here including looking for the completed assertion process
NSLog(@“att.com not found, OK TO READ CONTENTS”); 
 } 

else 

{ 

// an AT&T page, do not read any portion of the page 

NSLog(@“att.com found, DO NOT READ CONTENTS”); 

} 

	 	2.	 Application shall not have active debugging hooks in the commercial release runtime. 

Please Note: This is consistent with requirements communicated to and implemented by partners that have applications already in
production.

 Exhibit 8 

Terms of Service 
 This
Exhibit 8 (Terms of Service), is an exhibit to the Portal and Advertising Services Agreement, dated as of April 1, 2016 (the “Agreement”), between AT&T Services, Inc. (“AT&T”) and Synacor Inc.
(“Synacor”). All capitalized terms not otherwise defined in this Exhibit 8 shall have the meanings ascribed to them in the Agreement or the other exhibits thereto. 

AT&T High Speed Internet Terms of Service / att.net Terms of Use 

This Terms of Service & Terms of Use (“Agreement”) along with the AT&T Acceptable Use Policy, the AT&T privacy
policy, and the other documents incorporated by reference herein, set forth your obligations, AT&T’s obligations, and the rules you must follow when using the att.net portal and/or e-mail
(“Site”) and/or AT&T U-verse High Speed Internet, AT&T U-verse High Speed Internet Business Edition, AT&T High Speed Internet, AT&T High Speed
Internet Business Edition, AT&T High Speed Internet Direct, AT&T High Speed Internet Business Edition Direct, AT&T Dial, FastAccess DSL, FastAccess Business DSL, FastAccess Business DSL Direct, Wireless Broadband provided by BellSouth
Entertainment, LLC, BellSouth® Dial Internet Service (“Service(s)”). 

PLEASE READ THIS AGREEMENT CAREFULLY. This is a binding agreement between you (the Member Account holder) and the AT&T entity that
provides the Service and/or Site[1]. Your registration, payment for, or use of the Site and/or Service constitutes your agreement to be bound by the charges, terms, and conditions set forth in this Agreement, including those incorporated by
reference herein. 
 IMPORTANT: THIS AGREEMENT AFFECTS YOUR LEGAL RIGHTS. PARAGRAPH 12 REQUIRES ARBITRATION ON AN INDIVIDUAL
BASIS TO RESOLVE DISPUTES, RATHER THAN JURY TRIALS OR CLASS ACTIONS. PARAGRAPH 17 LIMITS AT&T’S LIABILITY. ARBITRATION TERMS FOR BUSINESS CUSTOMERS ARE SET FORTH ON SCHEDULE 1. PLEASE READ THEM CAREFULLY. 

This Agreement is based on four general principles. First, AT&T supports our customers’ right to free expression. Second, AT&T
will give our customers clear notice of any meaningful limitations on the Services. Third, AT&T will give our customers clear information about the experience they can expect when using the Services. Fourth, AT&T will provide consumer high
speed Internet access service in discrete, non-overlapping speed tiers. 
  

	1.	 Changes to this Agreement 

From time to time, we may change this Agreement. We will provide you with notice of material changes via either your Member Account e-mail address or any other email address you provide, posting online at http://www.att.com/internet-terms, recorded announcement, bill message, bill insert, newspaper ad,
postcard, letter, or call to your billed telephone number or U.S. mail. It is your responsibility to check for any such notices. Your continued subscription to the Service after the effective date of the change constitutes your acceptance of such
changes. 
  

	2.	 AT&T High Speed Internet Service 

a.   Service Description.
AT&T High Speed Internet Service (referred to as “the Service”) is composed of narrowband or broadband access to Internet, and offers you a capability for acquiring or retrieving information from; generating, storing,
transforming, processing, or utilizing information on; or making available information to other Internet end points connected directly or indirectly to AT&T’s network. Because the Internet consists of multiple interconnected networks and
most Internet end points (e.g., websites and other content providers) are not directly connected to AT&T’s network, AT&T must connect to and exchange traffic with other networks to provide its subscribers the capability of uploading
data to or downloading data from Internet end points that are connected to those networks. To that end, AT&T has entered into commercially negotiated agreements to exchange traffic with such networks on mutually agreeable terms. Consistent with
its longstanding practice, AT&T does not warrant that it will establish or expand the connections between its network and other networks except on such mutually agreeable terms. To the extent AT&T is unable to reach agreement on terms of
interconnection or network expansion with these other networks it could affect your service These impacts on your service performance are described in more detail in AT&T’s Open 

 CONFIDENTIAL TREATMENT REQUESTED 

 

 b.
  Internet notice. AT&T therefore makes no promise express or implied that you will be able to upload data to or download data from Internet end points connected to other networks at any particular speed. 

Like the other networks that make up the Internet, AT&T’s is a shared network, which means that the transmission links
and other network resources used to provide the Service are shared among AT&T’s subscribers. AT&T manages this network for the benefit of all users based on a variety of factors, and our technical expertise. 

c.   Speed, Service
Capability Speed Ranges, and Conditions that May Impact Service Performance. AT&T offers many broadband service options, each of which has a different service capability speed range. The term speed is commonly used as a shorthand way to
describe the capacity at which a particular broadband internet access service can transmit data. This capacity is typically measured in the number of kilobits, megabits or gigabits that can be transmitted in one second (Kbps, Mbps or Gbps). Some
applications like a short email without attachments or basic web browsing do not require high service capability speeds to function optimally, while other activities like transferring large data files can be performed faster with higher-speed services. Your service capability speed may not be suitable for some applications, particularly those involving real-time or near
real-time, high-bandwidth uses such as streaming video or video conferencing. 

The current speed ranges AT&T offers may be found at http://att.com/speedtiers, which identifies the downstream and
upstream rates at which your line transfers internet access data between the network interface device at your home, office or apartment building to the point you connect to AT&T’s network. Our wired broadband Internet access customers
should expect to see service capability speeds within the speed tier of their service plan. For example, a customer with AT&T’s High Speed Internet Elite Service should expect service capability download speeds between 3.1Mbps and 6.0 Mbps
between the network interface device at your premises and the point you connect to AT&T’s network. The high-end of this range represents expected maximum speed capabilities. For more information about
how AT&T helps transmit your information to points on the Internet, how AT&T manages the network, broadband options, including different service capability and expected and actual speed ranges, device attachment rules, activities which may
impair or degrade your internet experience and for additional information regarding network practices with respect to data usage caps related to AT&T Broadband Internet access services, please visit att.com/broadbandinfo. 

Because service performance varies on an end-to-end basis, AT&T’s service capability speeds are limited to, and
measured between, your location and a point on AT&T’s network, which constitutes only one segment of the end to end transmission path connecting the end user to Internet websites or content providers. End-to- end performance of your Service depends on a variety of factors, including (but not limited to): the number of subscribers simultaneously using the network; customer location; destination and traffic
on the Internet; Wi-Fi connectivity; interference with high frequency spectrum on your telephone line; wiring inside your premises, office or apartment; the capacity or performance of your devices or modem;
the server with which you are communicating; internal network management factors (including Overhead, which refers to the various control and signaling data required to achieve the reliable transmission of Internet access data); and the networks you
and others are using when communicating. In addition, your use of other AT&T services (such as U-verse video, voice, Unified Messaging and other services) that share the capacity of your broadband
connection with the Service may impact the amount of capacity available for your use of the Service at that particular time and thus affect the performance of the Service. Consequently, AT&T does not guarantee the performance of your service on
an end-to-end basis. 
 d.
  IP Addresses. AT&T High Speed Internet and AT&T U-verse High Speed Internet Services are provided with a dynamic Internet Protocol (“IP”) address, a static IP
address, multiple static IP address service (as applicable), or a privately managed IP address utilizing CGN (Carrier Gateway NAT) technology, at AT&T’s sole discretion. Static IP addresses are not available with all speeds. The dynamic IP
address is a single Internet address intended for use with a single Member Account and any associated Sub Accounts. The static IP address or multiple static IP address is intended for use with a single computer or a network of computer/servers. You
may not use the Service in a manner that is inconsistent with these intended uses. AT&T High Speed Internet services will support both IPV6 and IPV4 Internet addresses; however, to reach IPv6-exclusive
Internet content, some of your equipment may require upgrades or replacement. AT&T Dial service will support web sites that utilize IPV4, but it will not support IPV6-only web sites. For more information
about IPv6 and how it affects you, visit att.com/ipv6. 
 e.   Availability. The Service is not available in all areas, and may not be available at certain speeds (or at all) at your location, even if our initial
testing indicated that your line qualified for a particular speed or Service. 
 f.   Service/Site Changes. AT&T reserves the right to modify or discontinue the Service or Site (including rates and charges), temporarily or permanently. If
AT&T makes a change that would have a material impact on your Service, AT&T will give you notice. The terms and conditions for temporary changes, if any, will be included in the notice and incorporated by reference into this Agreement at:
www.att.com/temporaryterms. Your continued subscription to the Service after the effective date of the change constitutes your acceptance of the changes and the associated terms and conditions. In lieu of notice and website posting, AT&T may
instead, at its sole discretion, require customers to enter into an agreement with AT&T regarding temporary material changes. 

g.
  Conversion from DSL to U-verse High Speed Internet. When AT&T is able to provision U-verse High Speed Internet Service at your
location, we may, in our discretion, discontinue your DSL service and make available to you AT&T U-verse High Speed Internet at the then applicable U-verse rates,
terms and conditions, which may differ from your previous DSL Service rates, terms and conditions (including Bundle Discounts). If you are on a Term Plan and your price will increase as a result of this conversion, you will not have to pay any
applicable early termination fee (“ETF”) if you elect to cancel DSL Service. 
 Your new AT&;T U-verse High Speed Internet will require different customer premises equipment (“CPE”). When you are selected for conversion, we will provide at least thirty days notice of the discontinuation or
suspension of your service via e-mail, direct mail, bill page message, or bill insert. Thirty days after such notice, we may at our sole discretion, either disconnect your service, or temporarily suspend your
service for up to fifteen days. 
 h.
  Data Usage. For more information about the use of your residential High Speed Internet Service and the data plans that may apply to your service, how much data you use, and management of your data usage, please refer to
www.att.com/internet-usage. 
 i.   Wi-Fi Hot Spots (For HSIA). AT&T Wi-Fi Hot Spots may be available to you
as part of the Service, and the AT&T Wi-Fi Hot Spots will provide you with access to the Internet via certain AT&T high-speed Internet access points (Locations).
Primarily, this access is provided via a Wi-Fi network using an IEEE 802.11 standard. To access the Wi-Fi Hot Spots, you must have a device that is compatible with the
specific Wi-Fi equipment deployed at a Location. Access to the Hot Spots is intended for the limited purposes of assisting with access to the public Internet for e-mail
and web browsing or other purposes consistent with the AT&T Wi-Fi Terms of Service, which may be found at http://www.att.com/shop/legalterms.html?toskey=wiFiServices. In order to gain access to the
Internet at a Location, You may need your U-verse Member account information including your Member ID. If you are also an AT&T Mobility customer, You may
auto-authenticate at certain Locations without the use of your U-verse Member ID. The AT&T Wi-Fi Terms of Service will govern
your use of AT&T Wi-Fi Hot Spots. 
 j.   Business Customers. Additional terms and conditions for business customers are set forth in Schedule 1 attached hereto. 

 

	3.	 Registration and Membership 

When you complete the registration process for the Site or the Service, you become the “Member Account” holder. You must be 18 years
or older to be a Member Account holder. You will be asked to choose a unique “Member ID” for your account. Customers of the Service may also create up to ten “Sub Accounts” (each of which will have a separate password and Member
ID). Each Sub Account will also be required to accept this Agreement and complete the Sub Account registration. The Member Account holder is responsible for all activity associated with the Member Account and any of its Sub Accounts, including all
fees and charges, whether the charges are incurred by the Member Account or the Sub Accounts. Use of an AT&T Access ID subjects you to the AT&T Access ID Terms and Conditions (available at www.att.com/accessidterms), which are
incorporated herein by reference. 
 All information that you provide to AT&T must be accurate, including your name, address, credit or
charge card numbers and expiration dates, and any payment information (“Registration Data”). You are responsible for keeping such information up-to-date and must provide changes promptly to the AT&T Member Center by going to [Insert
Appropriate Link] 
  

	4.	 Pricing 

a.   Term Plans, Bundle
Discounts. When you purchased the Service, you agreed to specific price and plan, which may have included a term of one, two, or three years (“Term Plan”). Similarly, some plans may offer a discount on the Service if you sign up
for other AT&T services (“Bundle Discount”). You agree to maintain your Service and the bundled services for the applicable term. If you signed up for a Term Plan or a Bundle Discount, the price available with those plans is valid
until one of the following occurs, at which time your price may revert to the then-existing price for your Service: (1) the term expires; (2) you move from your current Service address to another
Service address; or (3) you drop one of the AT&T services you were required to purchase to receive the special rate. 

b.
  Dial-up Access Options and Toll Charges. AT&T will provide telephone numbers to connect to or register for the Service. Depending on location, local access numbers for dial-up Internet access may not be available in your area. Even access numbers in your area code may result in toll, usage, or long distance charges. Please check with your local phone company to determine whether
additional charges apply. You are responsible for selecting the best number for you and for all telephone fees and charges associated with the use of the telephone number you select. In no event will AT&T be responsible for any telephone fees or
charges incurred as a result of the telephone number you select. Use of the Service (or portions thereof) and of specific telephone numbers is subject to change or interruption at the telecommunication company’s or at AT&T’s
discretion.

 CONFIDENTIAL TREATMENT REQUESTED 

 

 c.
  is complete, unless the customer initially selects to self-install, and subsequently asks for a technician installation. 

d.   Method of Payment.
Your monthly charges may be billed via a monthly AT&T bill or to a credit card. Credit card billing is not available for AT&T High Speed Internet Direct. AT&T U-verse High Speed Internet
customers will automatically receive an online bill (see below), unless you specifically notify us that you want to receive a paper bill by calling the following number: Consumer 1-800-ATT-2020; Business: 1-800-321-2000. 

e.   Credit Card
Billing. You may be asked to provide us with a credit card number from a card issuer that we accept in order to activate your Service. You hereby authorize AT&T to charge and/or place a hold on your credit card with respect to any unpaid
charges for Services or any related equipment. You authorize the issuer of the credit card to pay any amounts described herein without requiring a signed receipt, and you agree that this Agreement shall be accepted as authorization to the issuer of
the credit card to pay any amounts described herein without requiring a signed receipt, and you agree that this Agreement shall be accepted as authorization to the issuer of the credit card to pay all such amounts. You authorize AT&T and/or any
other company who bills products or services, or acts as billing agent for AT&T to continue to attempt to charge and/or place holds with respect to all sums described herein, or any portion thereof, to your credit card until such amounts are
paid in full. You agree to provide AT&T with updated credit card information upon AT&T’s request and any time the information you previously provided is no longer valid. You acknowledge and agree that neither AT&T nor any AT&T
affiliated company will have any liability whatsoever for any non-sufficient funds or other charges incurred by you as a result of such attempts to charge, and/or place holds on, your credit card. If you
mistakenly provide a debit card number, instead of a credit card number, you authorize all charges described herein to be applied to such debit card unless and until you provide a credit card number. In the event you are enrolled, or later enroll,
in an automatic payment or electronic funds transfer plan, you agree that all sums described herein may be charged, at AT&T’s option, to the account number provided for such automatic payment or electronic funds transfer plan. When payment
is made by credit card or debit card, payment will also be subject to the terms and conditions established by the credit or debit card issuer. If charges cannot be processed through your credit card, or if your bank draft or electronic funds
transfer is returned for insufficient funds, we will charge you an additional $15.00. If the state law where you receive the Service requires a different fee, we will charge you that amount. 

f.   Online Billing for AT&T U-verse High Speed Internet Members. You must register online to establish a personal AT&T My U-verse Account and provide a billing email address. You will then be
able to view and pay your bill online by logging on to your personal AT&T My U-verse Account (username and password required). 

You understand that you have sole responsibility for the security of your password and you are solely responsible for notifying
AT&T if your password is lost or stolen. AT&T is not liable for any claims, costs, damages, or expenses arising from a lost misplaced, or stolen password. If you have forgotten your password or want to change your password for any reason,
you may request to reset your password online. It is your responsibility to notify AT&T immediately if your contact information changes. 

g.   Late Payment & Failure
to Pay. If you choose to have the charges for your Service added to your AT&T bill, and, if AT&T does not receive your payment before the next billing date, you shall pay to AT&T a late payment charge and/or an interest charge
allowed by applicable law, on all charges due and unpaid. Acceptance of late or partial payments (even if marked “Paid in Full”) shall not waive any of AT&T rights to collect the full amount due. Notice of any disputes must be in
writing and received by us within 30 days after you received your bill or you will waive any objection. AT&T may suspend or terminate Service if your payment is past due. If AT&T suspends your service for
non-payment, you must pay all past due amounts in order to have service restored, and you may also, at AT&T’s sole discretion, be required to pay a service restoral fee. In the event you fail to
pay AT&T or AT&T is unable to bill charges to your credit card, AT&T may assign unpaid late balances to a collection agency. You expressly authorize, and specifically consent to allowing, AT&T and/or its outside collection agencies,
outside counsel, or other agents to contact you in connection with any and all matters relating to unpaid past due charges billed by AT&T to you. You agree that, for attempts to collect unpaid past due charges, such contact may be made to any
mailing address, telephone number, cellular phone number, e-mail address, or any other electronic address that you have provided, or may in the future provide, to AT&T. 

h.   Returned Checks and other
Instruments. If any check, or other instrument is tendered by you and returned unpaid by a financial institution for any reason you will be charged a fee. 

i.   Bill Inquiries and Refunds.
If you believe you have been billed in error for the Services, please notify us within 60 days of the billing date by contacting Customer Service (Consumer 1-800-288-2020; Business 1-800-321-2000). AT&T will not issue refunds or
credits after the expiration of this 60-day period, except where required by law or regulation. Any amounts refunded in the form of bill credits, cash payments or any other form shall be inclusive of all
applicable taxes, fees and surcharges that were originally paid on such amounts. Credit amounts, such as customer loyalty rewards, that do not represent a refund of, or a discount to, the price paid for any good or service will not result in the
refund of any tax, fee, or surcharge previously paid by the customer. 
 j.   Refunds. Any amounts refunded in the form of bill credits, cash payments or any other form shall be inclusive of all applicable taxes that were originally
paid on such amounts. 

 CONFIDENTIAL TREATMENT REQUESTED 

 

	7.	 Equipment & Software 

Other than the equipment and/or software provided to you by AT&T for use with the Service, you must provide all equipment, devices and
software necessary to receive the Service. Any equipment or software that was not provided to you by AT&T, including batteries, is not the responsibility of AT&T, and AT&T will not provide support, or be responsible for ongoing
maintenance of such equipment. Any AT&T-provided modem, router or gateway will be either a new or a fully inspected and tested refurbished unit. Regardless of whether the equipment used to access your
Service (modem, gateway, etc.) is owned by you or AT&T, AT&T reserves the right to manage such equipment for the duration of your Service, and retains exclusive rights to data generated by the equipment. Neither you nor a third party may
change, interfere with, or block access to equipment data or settings. 
 AT&T will repair or replace damaged equipment as AT&T deems
necessary. You understand that repair or replacement of equipment may delete stored content, reset personal settings or otherwise alter the functionality of your equipment. If you own the equipment or the equipment is damaged due to your intentional
acts or negligence as determined by AT&T, you will be responsible for the price of repair or replacement. 
 a.   Additional Equipment Information for AT&T U-verse High Speed Internet Customers. AT&T will make available to
you certain equipment (which may include a modem/gateway located inside your premises, or Optical Network Terminal (“ONT”) which is a box that may be located inside your premises, on the outside of your premises, a central location in a multi-tenant building, or in your garage, where AT&T’s fiber network terminates or an Intelligent Network Interface Device (“iNID”) (which provide your services if you do not have a gateway), all
of which is herein collectively referred to as “U-verse Equipment”), required for your Service. If you have not purchased U-verse Equipment from AT&T or if
previously purchased U-verse Equipment is beyond the one (1) year warranty period (from date of installation) and requires replacement, then you agree to pay a monthly equipment fee for the U-verse Equipment, as part of your purchase of or continued use of the Service and/or other U-verse services. Equipment fee/Purchase options depend on the AT&T U-verse services you order and the installation options you choose. 
 The U-verse Equipment requires electrical power from your premises to operate, which you are responsible for providing. If there is a gateway at your premises, AT&T will not provide an initial gateway battery backup
unit or an initial backup battery. For Consumer Dial customers only, if there is an ONT located on the outside of your premises and you are the first customer at the premises to order AT&T services, AT&T will install an initial ONT power
supply unit and provide an initial backup battery for the ONT power supply box. For all other Consumer and Business customers, if there is an ONT anywhere on your premises, a battery backup will not be provided by AT&T. Any backup battery
solution other than that stated herein is your responsibility. You may choose to purchase battery backup for your Equipment from third party manufacturers or retailers. For more information and minimum specifications visit att.com/batterybackup.

 You hereby agree to be solely responsible for determining when backup batteries for any
U-verse Equipment require replacement and for replacing and recycling used batteries. You agree to read and follow all manufacturer or vendor directions for the replacement and recycling of backup batteries.
For more information and minimum specifications visit att.com/batterybackup. 
 Note that
U-verse Equipment without battery backup will not function in the event of a loss of customer supplied power. This will disrupt the U-verse Service as well as any
additional services that use the U-verse connection for transport (e.g. Voice over IP including e911). AT&T will have no liability for loss of any service(s) in the event of interruption of customer
supplied power, with or without battery backup present in the AT&T equipment. 
 Tampering with the U-verse Equipment, or attempting to connect the equipment to other hardware, will be treated as damage due to your intentional acts or negligence. You agree that you will use the equipment only for its intended use,
and not for any other purpose (such as on another AT&T network, or on another provider’s (non-AT&T) network). 

You agree to notify AT&T immediately, in writing or by calling the AT&T customer support line, if the U-verse Equipment is stolen or if you become aware at any time that Services are being stolen or fraudulently used. When you call or write, you must provide a detailed description of the circumstances of the theft,
including documentation of theft or fraudulent use of the U-verse Equipment or Services (such as a copy of a police report). You will be responsible for all charges incurred until you report the theft or
fraudulent use. You will also be responsible for stolen U-verse Equipment not owned by you, however, AT&T may in its sole discretion waive or reduce charges upon submission of documentation of theft or
other circumstances. Failure to provide notice to AT&T of theft in a timely manner may result in the termination of your Services and additional charges to you. Unless notified otherwise by AT&T, after you report the theft or fraudulent use
of the Services, you will remain responsible for paying your monthly fees for Services not stolen or fraudulently used. 

Return of equipment: if your U-verse service is provided by an iNID, you must return
the TV receivers. You should not return the iNID home networking hub, (Model# j38HG) or the ONT. All other unowned U-verse equipment must be returned to AT&T undamaged, within twenty one (21) calendar
days after the Service is terminated. If equipment is not returned within twenty one (21)

 CONFIDENTIAL TREATMENT REQUESTED 

 

 
calendar days, or is returned damaged, you will be charged for the value of the U-verse Equipment. We may retain any advance payment or deposit, or portion
thereof that previously had not been refunded, if you fail to return the U-verse Equipment within this time period. If all U-verse Equipment is returned within six
(6) months of termination, any fees charged for such U-verse Equipment will be refunded (other than fees for damages). No refunds will be made for U-verse Equipment
returned after six (6) months from termination. The return of equipment provisions also apply if your existing equipment is replaced or upgraded for any reason.

are available as part of the Site or Service (including email, message boards, clubs, and instant messages) and the Internet. Please remember that the Service is designed to appeal to a broad audience. It is your responsibility to determine whether
the features provided through the Site and Service are appropriate for a minor. 
 AT&T suggests that you take advantage
of the access controls offered with the Service, which allow you, as the Member Account holder, to block access to certain types of web content you may feel are inappropriate for minors. However, AT&T also recommends that you remain diligent in
the supervision of any minors in their use of the Service and the Internet. Access controls provided through the Service are intended as a guide only. Neither AT&T nor its licensors can be responsible for any content accessed by you or minors,
whether or not you take advantage of the access controls provided through the Service. In addition, neither AT&T nor its licensors guarantee the accuracy of such access controls, and you agree that you will not hold AT&T liable for any loss
or damage of any kind incurred as a result of the use of such access controls.

include, but are not limited to, the following: (i) a cap on data usage; (ii) a modification of a customer’s serving facility or service technology, and/or (iii) a modification of or a limitation on a customer’s data
throughput speed or data consumption. 
 A very small percentage of customers use the Service in a way which creates harm to
the network, compromised capacity, degradation in network performance or service levels, or which may adversely impact access to or the use of the Service by other customers. In the event that AT&T adopts a network management practice which will
apply to your Service, we will provide you with a notice, by web posting, bill insert, email, letter and/or other appropriate means, which describes the network management practice, explains how it will work, and explains how it could impact your
Service.

	12.	 DISPUTE RESOLUTION WITH AT&T BY BINDING ARBITRATION 

PLEASE READ THIS CAREFULLY. IT AFFECTS YOUR RIGHTS. 

Consumer Customers: See Arbitration sections below. Business Customers: See Schedule 1. 

Most customer concerns can be resolved quickly and to the customer’s satisfaction by calling our customer service department at 1-800-288-2020. In the unlikely event that AT&T’s customer service department is unable to resolve a complaint you may have
to your satisfaction (or if AT&T has not been able to resolve a dispute it has with you after attempting to do so informally), we each agree to resolve those disputes through binding arbitration or small claims court instead of in courts of
general jurisdiction. Arbitration is more informal than a lawsuit in court. Arbitration uses a neutral arbitrator instead of a judge or jury, allows for more limited discovery than in court, and is subject to very limited review by courts.
Arbitrators can award the same damages and relief that a court can award. Any arbitration under this Agreement will take place on an individual basis; class arbitrations and class actions are not permitted. For any non-frivolous claim that does not exceed 

 CONFIDENTIAL TREATMENT REQUESTED 

 

 
$75,000, AT&T will pay all costs of the arbitration. Moreover, in arbitration you are entitled to recover attorneys’ fees from AT&T to at least the same extent as you would be in
court. 
 In addition, under certain circumstances (as explained below), AT&T will pay you more than the amount of the arbitrator’s
award and will pay your attorney (if any) twice his or her reasonable attorneys’ fees if the arbitrator awards you an amount that is greater than what AT&T has offered you to settle the dispute. 

Arbitration Agreement 

a.   AT&T and you agree to arbitrate
all disputes and claims between you and AT&T. This arbitration agreement does not include claims against AT&T that are based in whole or in part on the Site. This agreement to arbitrate is intended to be broadly interpreted. It
includes, but is not limited to: 

	 	●	 	 claims arising out of or relating to any aspect of the relationship between us, whether based in contract,
tort, statute, fraud, misrepresentation or any other legal theory; 

	 	●	 	 claims that arose before this or any prior Agreement (including, but not limited to, claims relating to
advertising); 

	 	●	 	 claims that are currently the subject of purported class action litigation in which you are not a member of a
certified class; and 

	 	●	 	 claims that may arise after the termination of this Agreement. 

References to “AT&T”, “you”, and “us” include our respective subsidiaries, affiliates,
agents, employees, predecessors in interest, successors, and assigns, as well as all authorized or unauthorized users or beneficiaries of the Service or Site under this or prior Agreements between us. Notwithstanding the foregoing, either party may
bring an individual action in small claims court. This arbitration agreement does not preclude you from bringing issues to the attention of federal, state, or local agencies. Such agencies, can, if the law allows, seek relief against us on your
behalf. YOU AGREE THAT, BY ENTERING INTO THIS AGREEMENT, YOU AND AT&T ARE EACH WAIVING THE RIGHT TO A TRIAL BY JURY OR TO PARTICIPATE IN A CLASS ACTION. This Agreement evidences a transaction in interstate commerce, and thus the Federal
Arbitration Act governs the interpretation and enforcement of this provision. This arbitration provision shall survive termination of this Agreement. 

b.   A party who intends to seek arbitration
must first send to the other, by certified mail, a written Notice of Dispute (“Notice”). The Notice to AT&T should be addressed to: Office for Dispute Resolution, AT&T, 1025 Lenox Park Blvd., Atlanta, GA 30319 (“Notice
Address”). The Notice must (1) describe the nature and basis of the claim or dispute; and (2) set forth the specific relief sought (“Demand”). If AT&T and you do not reach an agreement to resolve the claim within thirty
(30) days after the Notice is received, you or AT&T may commence an arbitration proceeding. During the arbitration, the amount of any settlement offer made by AT&T or you shall not be disclosed to the arbitrator until after the
arbitrator determines the amount, if any, to which you or AT&T is entitled. 
 You may download or copy a form Notice
and a form to initiate arbitration from here: att.com/arbitration-forms. 
 c.   After AT&T receives notice at the Notice Address that you have commenced arbitration, it will promptly reimburse you for your payment of the filing fee, unless your
claim is for greater than $75,000. (The filing fee currently is $200, but is subject to change by the arbitration provider. If you are unable to pay this fee, AT&T will pay it directly upon receiving a written request at the Notice Address). The
arbitration will be governed by the Commercial Arbitration Rules and the Supplementary Procedures for Consumer Related Disputes (collectively, “AAA Rules”) of the American Arbitration Association (“AAA”), as modified by this
Agreement, and will be administered by the AAA. The AAA Rules are available online at www.adr.org, by calling the AAA at
1-800-778-7879, or by writing to the Notice Address. (You may obtain information that is designed for non-lawyers about the arbitration process at att.com/arbitration-information.) The arbitrator is bound by the terms of this Agreement. All issues are for the arbitrator to
decide, except that issues relating to the scope and enforceability of the arbitration provision are for the court to decide. Unless AT&T and you agree otherwise, any arbitration hearings will take place in the county (or parish) of your billing
address. If your claim is for $10,000 or less, we agree that you may choose whether the arbitration will be conducted solely on the basis of documents submitted to the arbitrator, through a telephonic hearing, or by an
in-person hearing as established by the AAA Rules. If your claim exceeds $10,000, the right to a hearing will be determined by the AAA Rules. Regardless of the manner in which the arbitration is conducted, the
arbitrator shall issue a reasoned written decision sufficient to explain the essential findings and conclusions on which the award is based. 

Except as otherwise provided for herein, AT&T will pay all AAA filing, administration and arbitrator fees for any
arbitration initiated in accordance with the notice requirements above. If, however, the arbitrator finds that either the substance of your claim or the relief sought in the Demand is frivolous or brought for an improper purpose (as measured by the
standards set forth in Federal Rule of Civil Procedure 11(b)), then the payment of all such fees will be governed by the AAA Rules. In such case, you agree to reimburse AT&T for all monies previously disbursed by it that are otherwise your
obligation to pay under the AAA Rules. In addition, if you initiate an arbitration in which you seek more than $75,000 in damages, the payment of these fees will be governed by the AAA rules. 

 CONFIDENTIAL TREATMENT REQUESTED 

 

 d.
  If, after finding in your favor in any respect on the merits of your claim, the arbitrator issues you an award that is greater than the value of AT&T’s last written settlement offer made before an arbitrator was selected,
then AT&T will: 

	 	●	 	 pay you the greater of the award or $10,000 (“the alternative payment”), whichever is greater; and

	 	●	 	 pay your attorney, if any, twice the amount of attorneys’ fees, and reimburse any expenses (including
expert witness fees and costs), that your attorney reasonably accrues for investigating, preparing, and pursuing your claim in arbitration (“the attorney premium”). 

If AT&T did not make a written offer to settle the dispute before an arbitrator was selected, you and your attorney will be
entitled to receive the alternative payment and the attorney premium, respectively, if the arbitrator awards you any relief on the merits. The arbitrator may make rulings and resolve disputes as to the payment and reimbursement of fees, expenses,
and the alternative payment and the attorney premium at any time during the proceeding and upon request from either party made within fourteen (14) days of the arbitrator’s ruling on the merits. 

e.   The right to attorneys’ fees and
expenses discussed in paragraph (d) supplements any right to attorneys’ fees and expenses you may have under applicable law. Thus, if you would be entitled to a larger amount under the applicable law, this provision does not preclude the
arbitrator from awarding you that amount. However, you may not recover duplicative awards of attorneys’ fees or costs. Although under some laws AT&T may have a right to an award of attorneys’ fees and expenses if it prevails in an
arbitration, AT&T agrees that it will not seek such an award. 
 f.   The arbitrator may award declaratory or injunctive relief only in favor of the individual party seeking relief and only to the extent necessary to provide relief
warranted by that party’s individual claim. YOU AND AT&T AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS OR REPRESENTATIVE
PROCEEDING. Further, unless both you and AT&T agree otherwise, the arbitrator may not consolidate more than one person’s claims, and may not otherwise preside over any form of a representative or class proceeding. If this specific
proviso is found to be unenforceable, then the entirety of this arbitration provision shall be null and void. 
 g.   Notwithstanding any provision in this Agreement to the contrary, we agree that if AT&T makes any future change to this arbitration provision (other than a change to
the Notice Address) during the period of time that you are receiving Services, you may reject any such change by sending us written notice within 30 days of the change to the Arbitration Notice Address provided above. By rejecting any future change,
you are agreeing that you will arbitrate any dispute between us in accordance with the language of this provision.

Provisioning of the Service is subject to the availability and the operational limitations of the requisite equipment and associated

and agree that AT&T and its third party providers have no control over third party networks you may access in the course of your use of the Service, and therefore, delays and disruptions of other network transmissions are beyond the control of

For AT&T U-verse High Speed Internet Business Edition (fiber-based only), any determination of whether the inside wire work will be provided by you or AT&T will be made at the time

WARRANTY TO CUSTOMER OR ANY OTHER PARTY FOR ANY WORK OR MATERIALS CONSTITUTING OR ASSOCIATED WITH ANY INSIDE WIRE. AT&T EXPRESSLY DISCLAIMS ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR USE, AND AT&T HAS NO RESPONSIBILITY TO

Internet Business Edition customer, you are also subject to the terms set forth in the service guides for these services, which are incorporated herein by reference and may be found at:

	 	●	 	 http://serviceguidenew.att.com/sg_flashPlayerPage/HSI (AT&T High Speed Internet Business Edition)

 4.   Reimbursement for Time, Materials and Expenses (Business Customers Only). If Customer
cancels an order for or terminates any Service or Service Component (other than as permitted for default by AT&T), or AT&T cancels an order for or terminates any Service or Service Component for cause, prior to its Service Commencement Date,
Customer will reimburse AT&T for time, materials and expenses incurred prior to the effective date of such cancellation or termination, plus any third party charges resulting from the cancellation or termination. 

5.   Arbitration Agreement: 

AT&T and you (“We”) agree to resolve all disputes between us through binding arbitration administered by the American Arbitration
Association (“AAA”) under its Commercial Arbitration Rules, as modified by this provision. 
 This agreement to arbitrate is broad,
and includes disputes of any type between AT&T (including its subsidiaries, affiliates, agents, predecessors, successors, and assigns) and you (including authorized or unauthorized users/beneficiaries of services or devices) under this or prior
agreements. We agree that WE are waiving the right to a trial by jury, to participate in a class action, or to seek remedies  

 CONFIDENTIAL TREATMENT REQUESTED 

 

 
beyond the extent necessary to provide individualized relief to, and affecting only, AT&T or You ALone. WE AGREE NOT TO ACT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED OR DE FACTO CLASS
OR REPRESENTATIVE PROCEEDING, OR AS A PRIVATE ATTORNEY GENERAL OR ON BEHALF OF THE GENERAL PUBLIC. Except for matters relating to arbitrability or to the scope and enforceability of the arbitration provision or the interpretation of the
limitations on class, representative, private attorney general, and non-individualized relief, all issues are for the arbitrator to decide. 

A party seeking arbitration must first send to the other, by certified mail, a written Notice of Dispute (“Notice”). Notice to
AT&T must be addressed to: Office of Dispute Resolution, AT&T, 1025 Lenox Park Blvd., Atlanta, GA 30319 (“Notice Address”). The Notice must (a) describe the basis of the claim or dispute; (b) describe the specific relief
sought (“Demand”); and (c) provide your AT&T account number. If We do not resolve the claim within 30 days after receipt of the Notice, either of us may commence an arbitration. The amount of any settlement offer made by AT&T
or you shall not be disclosed to the arbitrator until after the arbitrator determines the amount of any award on the merits. 
 Unless We
agree otherwise, any arbitration hearings will take place in the county of your billing address. AT&T will pay all AAA filing, administration, and arbitrator fees for a claim brought by AT&T or for a claim or Demand valued at up to $25,000
brought by You. If the arbitrator finds that your claim or Demand is frivolous or is brought for an improper purpose (as measured by the standards in Federal Rule of Civil Procedure 11(b)), then the payment of fees will be governed by the AAA rules
and You agree to reimburse AT&T for fees already paid by AT&T that are your obligation under the AAA rules. 
 If you complied with
the notice procedures above; the value of your claim or Demand is $25,000 or less; and the arbitrator awards you an amount greater than the value of AT&T’s last written settlement offer made before an arbitrator was selected (or any amount
if AT&T made no offer), AT&T will: 

	 	●	 	 Pay you the award or $10,000, whichever is greater (“Alternative Payment”); and

	 	●	 	 Pay your attorney, if any, the amount of attorneys’ fees and expenses (including expert witness fees and
costs) that your attorney reasonably accrues for investigating, preparing and pursuing your claim in arbitration (“Attorney Award”). 

The arbitrator may rule on the payment of fees, expenses, and the Alternative Payment and Attorney Award during the proceeding and within 14
days after his/her final ruling on the merits. In assessing whether the award is greater than the value of AT&T’s last written settlement offer, the arbitrator may consider only those attorneys’ fees or expenses that you incurred
through the date of your Notice and which had been awarded to You. You may also recover attorneys’ fees and expenses under applicable law, but you may not recover duplicative awards of attorneys’ fees or expenses. 

This Agreement evidences a transaction in interstate commerce, and the Federal Arbitration Act governs. This arbitration provision survives
termination of this Agreement. As the exclusive alternative to arbitration, AT&T or you may commence an individual action in Small Claims Court. If a court rejects enforcement of any of the limitations on class, representative, private attorney
general, or non-individualized relief as to a particular claim for relief, then that claim (and only that claim) must be severed from the arbitration and may be brought in court. Notwithstanding any provision
in this Agreement to the contrary, We agree that if AT&T makes any future change to this arbitration provision (except a change to the Notice Address) during your Service commitment, you may reject any such change by sending AT&T written
notice within 30 days of the change to the Notice Address. By rejecting any future change, You agree to arbitrate any dispute in accordance with the language of this provision. 

If you are located in Puerto Rico, in addition to pursuing arbitration in accordance with this provision, you may notify the Telecommunications
Regulatory Board of Puerto Rico of your grievance. Mail: 500 Ave. Roberto H. Tood (Parada 18), San Juan, Puerto Rico 00907-3941; Phone: 1-787-756-0804 or 1-866-578-5500; Online: jrtpr.gobierno.pr.

 Violence and threatening behavior are not permitted. Employees should report to work in condition to
perform their duties, free from the influence of illegal drugs or alcohol. The abuse of alcohol or illegal drugs in the workplace will not be tolerated. 

EMERGENCY and SAFETY PROCEDURES/PRECAUTIONS 
 Information in
this section is designed to help employees understand the actions that will be taken by Synacor management and the building management (Pioneer Management) to provide a basis for emergency response plans. 

Fire/Life Safety 
 ● Pioneer Management has many systems designed to minimize the chance of a life-threatening emergency and to reduce the damage in the event such an emergency does occur. The building is inspected
regularly and monitored 24 hours a day, seven days a week. 
 ● When an alarm is
triggered, a signal is sent to the Buffalo Fire Department and the control panel in the main lobby will pinpoint the source of the alarm. During an emergency, the elevators will not respond to call buttons. USE THE STAIRS. 

● Fire drills are held regularly and everyone is required to participate. The
building will give prior notice to each office. 
 ● If you discover a fire,
pull the nearest alarm station. Pull stations are located at all stairwell entries. If there is time, dial 911, from a safe place. Building Emergency 

● Call the Administrative Assistant at extension 3311. 

Medical Emergency 
 ● Call Paramedics. Dial 5911. Tell them your floor number and direct the medical team to the person in need of assistance. 

If You Hear an Alarm 
 ● Immediately evacuate the premises to the common area hallway. 
 ● Close doors as you evacuate, but do not lock them. 
 ● Take only essentials and do not return for additional belongings or papers. 
 ● Follow evacuation/relocation instructions given to you by the Safety Committee. 
 ● Do not use the elevators. Elevators will return to the lobby to await firefighters. 

● Feel doors before opening. Do not open any doors that are hot to the touch. 

● If you are physically challenged, proceed to the exit and await help from a
Safety Committee member. 
 ● After an alarm, whether false or otherwise, the
alarm bell may ring a few times while it is being reset. Please be patient. You will be notified when you can return to your work areas. 
 Bomb Threat 

● Building management will notify tenant contacts via telephone as quickly as
possible. They will provide all the information that is known at that time. It is the responsibility of the Company to decide whether or not to evacuate. 

● If a device is found, management will, in conjunction with local authorities,
evacuate the building.

 CONFIDENTIAL TREATMENT REQUESTED 

 

 ● If you receive a bomb threat
by telephone, complete a “Bomb Threat Report Form” if possible. All members of Human Resources keep these. 

o Discreetly attract the attention of a co-worker and have him or her listen in. 

o Get as much information as possible from the caller about the location and type of bomb, its detonation time, method of
detonation, and the reason for its placement. Note any information about the caller—male/female, adult/juvenile, educated or coarse voice, angry, background noises, etc. 

● Call the Administrative Assistant at extension 3311. 

● Check your area for any unusual or suspicious objects. 

● Inform someone from Management. DO NOT TOUCH OR DISTURB ANY SUSPICIOUS OBJECT.

 PCD Safety 
 Conducting telephone calls or utilizing PCDs
while driving can be a safety hazard. Drivers should use PCDs while parked or out of the vehicle. If employees must use a PCD while driving, Synacor requires the use of hands-free enabling devices. 

SAFETY & HEALTH 
 The safety and health of all
employees is important to Synacor. The Company expects its employees to be safety-conscious and to immediately inform management of any conditions that might cause an accident. For the protection of all employees, any unsafe conditions, injuries or
accidents must be immediately reported to management. Medical treatment should be obtained for minor injuries. 
 DRUG and ALCOHOL USE POLICY 

Synacor provides a safe and productive work environment for all employees. Employees shall not be involved with the unlawful use, possession, sale, or
transfer of drugs or narcotics in any manner that may impair their ability to perform assigned duties or otherwise adversely affect the Company’s business. Further, employees shall not possess alcoholic beverages in the workplace or consume
alcoholic beverages at the workplace or during work time. 
 ● Employees are
expected to report for work and remain at work in a condition to perform assigned duties free from the effects of alcohol and illegal drugs. 

o Alcohol abuse or illegal drug use and their physiological effects represent a threat to the well-being and security of employees and
could cause extensive damage to the Company’s reputation and community standing. 
 o Any involvement with alcohol or drugs that
adversely affects the workplace or the work environment will not be tolerated. 
 o Off-the-job illegal drug activity or alcohol abuse
that could have an adverse effect on an employee’s job performance or that could jeopardize the safety of other employees, the public, Company equipment, or the Company’s relations with the public, will not be tolerated. 

o Violations of this policy will result in disciplinary action, up to and including termination of employment. 

● There may be occasional events where it is permissible to consume alcohol in
moderation, with management approval. Employees who consume alcohol under such circumstances shall not report back to work during that workday.

always keep in mind that email and the Internet are public methods of communication. When sending information via email or the Internet, there is always the possibility that unauthorized individuals will view the information. Never send
confidential, proprietary, or trade secret information without first obtaining authorization from your supervisor. This type of information is a valuable asset of Synacor, Inc., and each of us must ensure that it is protected from unauthorized
disclosure. 
 Responsibility for Passwords 
 Employees are
responsible for safeguarding their passwords for access to the computer system. Individual passwords should not be printed, stored online, or given to others. Employees are responsible for all transactions made using their accounts. No employee may
access the computer system using another employee’s password or account. Employees may not disguise their identity while using the computer system. 

Passwords Do Not Imply Privacy 
 Use of passwords to gain
access to the computer system or to encode particular files or messages does not imply that employees should have an expectation of privacy in the Synacor Employee Handbook material they create or receive on the computer system. Synacor, Inc., has
the right to inspect, without prior notice, all material stored on its computer system.

to solicit others, whether for a commercial or a charitable purpose, or to access or display material of a sexual or harassing nature. Employees are permitted to use Synacor resources for other personal reasons on a limited basis, but only on the
premise that use does not interfere with their own work, with the use of company resources for Synacor business, with the rights of others, or that use is not related to an illegal activity or to any outside business. 

Theft of any Synacor property or information—in any form—will be prosecuted. 

The following minimum standards apply, unless an exception has been documented, approved and submitted according to the Exception Handling process.
(Review the Exception Handling section below).

files should be stored on network file servers to ensure proper backup, recovery and protection. Electronic (and paper) files are the property of Synacor—users have no expectation of personal privacy in their use of company communication
systems or information sent to and from these systems. 
 Network Systems Security 

Network systems, including remote Internet users and front-end network servers compromise the methods of external access into the Synacor closed and
private environment. Network Security represents a physical/logical layer (buffer) of protection for between the outside and internal Synacor host systems. 
 The
following identifies the minimum security requirements for network systems. 
 Corporate LAN Access 

● All users (contractors, vendors, employees) connecting to the Synacor Corporate
Local Area Network (LAN) must have anti-virus software installed and receive a virus scan from the IT Enterprise Operations group prior to connection. 

● All employee users must also have the company standard desktop management and
security software that is supported by IT Enterprise Operations installed on their computer. 
 ● All users are expected to log off the network or use the Windows “Lock Computer” feature when they will be away from their computer. (Press CtrlAlt-Delete to access the Windows Security
screen). If the Screen Saver function in Windows is used to restrict access during periods of inactivity, it must be set to require a password to resume and to activate after a MAXIMUM of 10 minutes of inactivity. 

● All employee users must use the company standard personal computing device
issued by Synacor. Personal computers are prohibited unless an approved exception is filed according to the Exception Handling process in this policy. 

Remote Access 

Dial-Up/Broadband and Virtual Private Network (VPN) access to internal Synacor networks MUST be controlled via individual user
identification and authentication (logon id and password), separate and distinct from that required by host systems (i.e., network-layer authentication). Contractors will NOT be provided remote dialin access to Synacor network resources unless
explicitly authorized by the sponsoring VP and the VP of Information Technology.

● All connectivity from the public Internet to the Synacor internal network will
be controlled through the use of firewall and intrusion detection devices approved by Network Operations. All ports not necessary for operations must be closed. 

● All systems must be behind a secure gateway, firewall or a DMZ (Demilitarized.
Zone) with the use of a “Honey Pot.” 
 ● Internet access to
“protected” web resources MUST be controlled through authentication, authorization, and accounting security technology—using appropriate host security configurations

Authorization (Access to Resources) 

Transaction security for accessing host system resources MUST be controlled via access control list (ACL) methods including: 

● Defining specific users (or groups of users) to specific system resources
(files, programs, devices, utilities, etc.), using the least privilege concept. 

● User access MUST be approved by the owner of the application, system, or
network. 
 ● Access to Production resources MUST be limited to only those
operational staff having a legitimate need to access, and at all times segregation of duties must be maintained.

 CONFIDENTIAL TREATMENT REQUESTED 

 

 
executive system access are responsible for taking extra measures to ensure system-level access is managed to prevent unauthorized access. 

Revoking Access 

Access should be proactively managed to ensure that access is granted to only those individuals with a current business need. 

● Users’ logical access to the Synacor network and other Host Systems MUST
be revoked within one (1) hour of termination from the Company (for any reason). 

● Users’ logical access and privilege levels should be updated to remove
access no longer needed when the user changes jobs or their duties no longer require access. 
 ● Access should be reviewed at a MINIMUM of once a year. All access not associated with valid users and current business needs must be revoked. More frequent reviews may be warranted for situations
including, but not limited to: critical systems, systems that provide access to sensitive data and for Administrative System access. Business owners of systems and IT are expected to evaluate the risks of invalid access to systems or applications
they have responsibility for and implement a more frequent schedule that is appropriate to helping ensure the security of that system. 

Backup and Recovery 

Critical data and applications require additional precautions to support business continuity. Critical systems (data and applications)
will be defined in the Company’s Disaster Recovery Plan. 
 ● All critical
data and applications must have backup and recovery plans that consider business and legal requirements. 
 ● All critical data and applications must be backed up to an off-site location. 
 ● Time length of storage is defined within individual systems policies. 
 Audit
and Logging 
 Security logging and auditing for host systems must be provided to include securityrelevant information (as
technology permits) such as: 
 ● User logon and resource access violations
(e.g., log of invalid logon attempts and attempts to access resources for which the user is not authorized). 
 ● System activity logging for all security record modifications. 
 ● Ability to audit/log specific user and/or resources on-demand. 
 ● Analysis of vulnerability weaknesses on a regular basis 
 Application
Security 
 Application systems, regardless of their platform and specific utilities used (e.g., databases, packaged software,
custom software, etc.) MUST provide positive access control (least privilege) over Synacor programs and data files (as technology permits). 

● Business computer applications MUST enforce those security features identified
in Host System Security section. 
 ● Any changes to production application
programs must adhere to the Synacor Change Control Processes (CCP), including testing and approvals. 
 ● Any non-Synacor provided software, including public domain software, must be approved by IT Enterprise Operations. 

Email/Fax/Voice Security

 CONFIDENTIAL TREATMENT REQUESTED 

 

 Data transmitted via email and facsimile, especially when transmitted over the public Internet (e.g.,
email), should always be reviewed to ensure that confidential or restricted distribution is provided in accordance with this Policy 
 Physical Security 

Access 

Access to Synacor facilities MUST be positively controlled to ensure that only authorized employees, contractors, and visitors are
allowed access. 
 ● Visitors who have not been appropriately provided an
unescorted access badge MUST be escorted by a Synacor employee at all times. 

● Access to computer rooms and engineering facilities MUST be provided on a least
privileged basis. At no time will contractors/vendors be allowed access to these locations without an “on-property” escort by the sponsoring entity. 

Property Protection 

All Synacor-owned laptop computers and other small valuable peripherals (e.g., removable drives, PDAs, cellular devices) MUST be secured
at all times. These devices MUST never be left unsecured in open areas, in vehicles, or at a vendor/customer facility. It is also highly recommended, that, in large open areas, these devices are not left unsecured when not directly supervised by the
owner. 
 Security Investigations 

Human Resources entity may at any time perform investigations, reviews and/or monitoring (including transmissions via telephone and
email) of specific individuals or groups of individuals. These security investigations may be done on a periodic basis or in cases of reasonable suspicion, such as possible theft, vandalism, violation of laws, regulations, corporate policy, or if
similar inappropriate activity is suspected. 
 Exception Handling 

Exceptions to requirements in Informational Classification & Control through Physical Security sections of this policy will be
considered when technology or business constraints prevent compliance or when management assessment determines that the business risks do not justify the added costs (time and/or dollars) to comply. 

● To be considered a valid exception to this policy, an approved Exception
Request must be on file with the Enterprise Protection Exception Handling Manager. (See Enterprise Protection Exception Handling Procedures for details.) Valid Exception Requests require: 

o Documented risk assessment/business impact analysis 

o Documented approval by the relevant “Protection” (Technology or HR) Executive and the relevant Business Executive(s)
indicating agreement with the risk assessment and acceptance of the risk. 
 ●
Exceptions must be reviewed annually. If the exception is still warranted, both the Technology Executive and the Business Executive must approve the exception for another year. If the exception is no longer warranted, then a date must be established
for compliance.
