To be eligible for the Feature Enhancement Rate, rather than the standard Base Rates, a Statement of Work or Change Order must be executed by the parties in a [*******] where the applicable [*** ********** level for that ******* is below **** ***] when measured following the process outlined in Schedule F, “Fees,” Section 1, “CSG Services,” Section II, “Interfaces,” subsection C, “CSG SmartLink® BOS (SLBOS) and Event Notification Interfaces (ENI) (Note 1),” Note 6. For purposes of clarification, the FER (i) is applicable only for “[***** ***]” Statements of Work and (ii) is not applicable for any Statements of Work for “[******” ***********]. If Customer executes a Change Order during a [*******] where it is eligible for the FER, but the related Statement of Work was executed in a [*******] where Customer was not eligible, the FER shall only apply on the additional [***** ****] added by said Change Order.

Note 2: The Rates specified in line items A and B of the fee table above will be subject to the credits, detailed below, commencing [**** ** ****], based on executed Statements of Work or Change Orders providing for Technical Services to be provided to Customer by CSG resources on a [**** *** ********* resource services ***** *****, not on a ***** *** *****, and the ********** number of ***** achieved by Customer in a ******** **** (the “****** SOW Resources Services *****]”):

For clarity, the Technical Service [***** ******] specified in Article 3.2 of the Agreement shall not count toward the ****** SOW Resources Services Hours. For [******** **** **** only, the threshold will be ***** ******* (***) of the ******] thresholds specified above; for example, for the period of [**** ** ****, through ******** *** ****], Customer will receive the [**** ******* (**) credit on ***** billed at the Technical Services Rate of ****.** when ****** SOW Resources Services ***** are ***** ******* (***) of the ************ ******** (******) (i.e., of a ******** ******** (******) ****** SOW Resources Services *****] threshold).

Note 3: The [****** SOW Resources Services ***** will commence as of **** ** ****. To be eligible to count towards the ****** SOW Resources Services ***** (as defined in Note 2), a Statement of Work or Change Order must be executed by the parties in a ******* where the applicable *** processing level for that ******* is ***** **** ***] when measured following the process outlined in Schedule F, “Fees,” Section 1, “CSG Services,” Section II, “Interfaces,” subsection C, “CSG SmartLink® BOS (SLBOS) and Event Notification Interfaces (ENI) (Note 1),” Note 6.

The discount is not stepped. The percentage discount for the applicable [***** will be established by the *******] threshold achieved in the period. For example, if [********* ******** (******) ***** are billed in the period, the ***** ******* (**) discount will be applicable for *** ********* ******** (******) *****].

Note 5: Technical Services Hours applicable in any project documented in a Statement of Work or Change Order for “[***** ****]” shall not be counted toward the [****** SOW Resources Services *****].

Note 2: All installation and startup services and the associated fees shall be set forth in a mutually agreed upon Statement of Work.

(a) Conversion Schedule. Additionally, Customer has the option to elect to move to the Final Transition Processing Level Phase at any time during the Initial Transition Phase upon Customer providing CSG with ****** (**) **** prior notice (e-mail shall suffice).

Customer will then continue to be invoiced for the Final Transition Phase through the [********* ****** ** *** ****].

CSG shall provide a copy of the [********* Measurement List to Customer no later than the ***** (***) ******** *** of the ***** *********** following the *** ** *** ******** *******]. The [****** *** value on the ********* *** Measurement List (“Determining *** Value”) will be the *** value used to determine the *** processing level applicable going forward for the **** ******** ******* (“New ***]”).

For clarification purposes, SLBOS Fees shall in no event be [**** than the ******* of the *** processing level supporting up to each ***] level as prescribed by the Transition Phase table in Note 5 specified above.

Note 7: [*** measurements will consist of the ******* of measurements taken over ******* (**) ******] intervals.

Note 8: [*****] “requests” shall include any upstream transaction that is generated by or on behalf of Customer from either a Customer or a third party application, excluding transactions associated with (i) [*** ***** ***** ************, (ii) ***** ***** ****, (iii) any CSG Products or Services using SLBOS to communicate ***********] with other CSG Products or Services, unless noted otherwise or (iv) [************ **********] with the CTER environment.
