This Thirty-third Amendment (the “Amendment”) is made by and between CSG Systems, Inc., a Delaware corporation (“CSG”), and Charter Communications Holding Company, LLC, a Delaware limited liability company (“Customer”).  CSG and Customer entered into that certain Amended and Restated CSG Master Subscriber Management System Agreement dated February 9, 2009, as amended (the “Agreement”), and now desire to further amend the Agreement in accordance with the terms and conditions set forth in this Amendment.  If the terms and conditions set forth in this Amendment shall be in conflict with the Agreement, the terms and conditions of this Amendment shall control.  Any terms in initial capital letters or all capital letters used as a defined term but not defined in this Amendment shall have the meaning set forth in the Agreement.  Upon execution of this Amendment by the parties, any subsequent reference to the Agreement between the parties shall mean the Agreement as amended by this Amendment.  Except as amended by this Amendment, the terms and conditions set forth in the Agreement shall continue in full force and effect according to their terms.

Whereas, the parties entered into that certain Letter of Authorization entitled "User Defined Parameter Functionality - Proof of Concept" effective as of August 1, 2012 (CSG document no. 2313707) (the LOA"); and

Whereas, as a result of the Proof of Concept ("POC"), Customer advised CSG of its intent to continue to use the User Defined ("UD") Parameter Functionality of the Complex Composite Services in Customer's production environment as an Additional Service; and

Whereas, pursuant to the LOA, following completion of the POC period on or about August 31, 2012, and upon implementation of the UD Parameter Functionality into Customer's production environment, Customer will be subject to Complex Composite Services fees for each Complex Composite Service on which UD Parameter Functionality exists; and

Whereas, pursuant to the LOA, the parties agree to amend the Agreement as provided herein,

Now, therefore, CSG and Customer agree to the following upon the Effective Date:

1.    Customer desires to receive and CSG hereby agrees to provide Complex Composite Services that will allow Customer the use of UD Parameter Functionality services.  

2.    Therefore, Schedule C, "Recurring Services," of the Agreement is hereby amended by adding Complex Composite Services as follows:

3.  As a result, Schedule F, “Fees,” Section entitled “CSG Services,” Section I. entitled “Processing,” shall be amended to add a new subsection L. entitled “Complex Composite Services,” as follows:
