Further, Letters can be stored in the same CSG InView storage instance. As a result, CSG InView will permit Customer access to its Letters for a period of up to [*** (*) ******] from the date that each such Letter is available for viewing (the “Letter Retention Period”), after which time PDF images of Letters will no longer be accessible to Customer.”

b) Exhibit C-2, Print and Mail Services, shall have a new Section 9, “Letters” added as follows:

“9. Letters. Letters provides Customer with (a) processing Customer-requested letters for Customer’s Connected Subscribers, Acquired Non-ACP Subscribers and recipients selected and specified by Customer. Letters will, collectively, include each of (i) Customer-precomposed letters via a file feed from Customer to CSG (the “File Feed Precomposed Letters”) and (ii) Customer-generated letters from Customer’s utilization of CSG’s SaaS document composition platform entitled “CSG Communication Builder” (the “Communication Builder Letters”). Customer’s utilization of File Feed Precomposed Letter or Communication Builder Letter will be determined solely by Customer for each Letters request from Customer to CSG; and (b) adding email as an alternate communication delivery channel to send Letters content via email.

For purposes of clarification:

Communication Builder Letters. CSG will provide Customer with access to CSG Communication Builder, a CSG SaaS document composition platform from which Customer will have the ability to design, edit and print digital and hard copy letters and utilize preset templates with Customer branding capabilities stored on CSG Communication Builder from Customer’s web browser for Customer to create, validate, preview, update and approve Letters for delivery via Print and Mail Services (that will include print letters and postcards) and Alternate Communication Delivery (for digital letters) for Connected Subscribers, Acquired Non-ACP Subscribers and recipients, Communication Builder Letters will be sent, as determined solely by Customer, via (i) Direct Solutions (Print and Mail) and via (ii) email (“Alternate Communication Delivery) for Connected Subscribers, Acquired Non-ACP Subscribers and recipients. The specific terms and conditions for any Communication Builder Letter will be set forth in mutually agreed Statements of Work, E-SOWs or Letters of Authorization.

File Feed Precomposed Letters. CSG will provide Customer with access to a Graphical User Interface (“GUI”) through web application screens that allow Customer to create, edit, validate, preview, update, and approve Letters for delivery via Print and Mail and, electronically, via Alternate Communication Delivery for Connected Subscribers, Acquired Non-ACP Subscribers and recipients. The specific terms and conditions for any File Feed Precomposed Letter will be set forth in mutually agreed Statements of Work, E-SOWs or Letters of Authorization.

Alternate Communication Delivery. Alternate Communication Delivery will be available via email as an alternate delivery model for digital Letters for Connected Subscribers, Acquired Non-ACP Subscribers and recipients.”

Note 1: An [**********] physical page means text items, such as billing details or system-generated statement messages that overflow onto an [**********] physical page with no more graphics than those graphics tied to messages via the statement message module and no programmer intervention. The page may include static Customer information, such as, policies and procedures, payment locations, franchise authorities, etc. If Customer is using AESP or enhanced past due notices, only graphics from the AESP graphics library may be used on the [**********] physical page. If Customer is using AESP or enhanced past due notices, the [**********] physical page has duplex capability.

Note 5: CSG shall provide [*******] turnaround, excluding major [********], for Letters.

Note 6: Customer may elect to use optional Vantage Direct service for Letters to allow for the ability to target market their customers.

Note 19: For [*********] purposes, material (paper, carrier and remit) as reflected in subsection VI.A - VI.C shall be added to both (i) Section I, AESP Statement processing, subsection A, "processing for AESP Statement Format" fee and (ii) Section II, Letter processing, subsection C, Letters, "[*****] physical page" processing fee. Further, paper, as reflected in subsection VI.A, shall be added to both (i) Section I, AESP Statement processing, subsection B, "[**********] physical page" and (ii) Section II, Letters Processing, subsection B, "********** physical page for Letters" fee.

Note 20: For clarification purposes, Customer is not responsible for paying any sales tax arising from CSG's purchase of those materials reflected in subsections VI.A through VI.C, as CSG is responsible for paying the sales tax associated with the purchase of these materials. However, if Customer uses any materials other than those listed in subsection VI.A through VI.C, Customer is responsible for sales tax arising from such use. For illustrative purposes only, assume that Customer uses an expansion envelope with a current price of [*******]. Based upon the pricing set forth in the above table, CSG will reduce that price by [*******] (the value of the generic carrier), and the Customer's effective price will be [*******]. This effective price will appear on the invoice and Customer will be responsible for any sales tax based on the individual taxing states.

IN WITNESS WHEREOF the parties hereto have caused this Twenty-First Amendment to be executed by their duly authorized representatives.
