TWENTY-SIXTH AMENDMENT

TO

CSG MASTER SUBSCRIBER MANAGEMENT SYSTEM AGREEMENT

BETWEEN

CSG SYSTEMS, INC.

AND

DISH NETWORK L.L.C.

This TWENTY-SIXTH AMENDMENT (this “Amendment”) is made by and between CSG
Systems, Inc., a Delaware corporation (“CSG”), and DISH Network L.L.C., a
Colorado limited liability company (“Customer”). This Amendment shall be
effective as of the date last signed below (the “Effective Date”). CSG and
Customer entered into a certain CSG Master Subscriber Management System
(Document #2301656) effective as of January 1, 2010 (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.

CSG and Customer agree to the following upon the Effective Date:

 

1. Customer desires, and CSG agrees, to standardize the interfaces and
applications between Customer’s QT04, QT05 and QT07 environments.

 

2. Exhibit A, Environment Matrix, to this Amendment sets forth the various
environments impacted by the Integrated Operations Testing (“IOT”) environment
standardization. The matrix states (i) whether an environment is needed by
Customer in its QT04, QT05 and/or QT07 environments, (ii) if an environment is
needed, the environment(s) in which standardization has been completed, and
(iii) the environment(s) in which standardization needs to be completed pursuant
to this Amendment.

 

3. The following assumptions apply in connection with the IOT environment
standardization:

 

  •  

The QT04, QT05 and QT07 environments are not designed for load testing. Any load
testing will need to be requested by Customer and coordinated by CSG, with the
potential for increased costs.

 

  •  

The QT04, QT05 and QT07 environments are not high availability environments,
meaning, there is no redundancy built into any of the hardware or software.

 

  •  

Paper statements must be requested by Customer for any or all of the IOT
environments and will not generate automatically.

 

  •  

Statements will be available in DirectNet for the QT04, QT05 and QT07
environments.

 

  •  

Nightly cycle will occur ***** *** **** per ****, between **** **** and ****
**** prevailing Mountain time, with the understanding that Customer can request
a ****** ********* cycle on an exception basis with a minimum of *** *** days
advance notice.

 

  •  

Current IOT support requirements are set forth in the Twelfth Amendment to the
Agreement (CSG #2308298).

 

  •  

Hardware purchased for SLBOS pursuant to this Amendment allows for isolated
environments for QT04 in which each environment can support its own version of
code without impact to another environment.

 

  •  

Items on Exhibit A, Environment Matrix, listed in the “Environment Needed”
column as “No” have been reviewed by Customer and Customer agrees that to
Customer’s knowledge those items are not required at this time. Future requests
for those items listed in the “Environment Needed” column as “No” will be
handled independent of this Amendment.

--------------------------------------------------------------------------------

*** Confidential Treatment Requested and the Redacted Material has been
separately filed with the Commission.

 

  •  

Delivery of the SLBOS server requires approximately an ***** *** **** lead time
(*** *** ***** to order and *** *** ***** to configure).

 

  •  

Code deployments into the QT04, QT05 and QT07 environments will follow the
guidelines and assumptions set forth in the Twentieth Amendment to the Agreement
(CSG #2309714).

 

4. As a result, Schedule F, Fees, CSG Services, Section I, entitled
“Processing,” subsection G entitled “Integrated Operations Testing Environment
for QT05 and QT07” shall be deleted in its entirety and replaced with the
following:

G. Integrated Operations Testing Environment for environments QT04, QT05 and
