EXHIBIT 2.19L THIRTY SEVENTH AMENDMENT TO RESTATED AND AMENDED CSG MASTER SUBSCRIBER MANAGEMENT SYSTEM AGREEMENT BETWEEN CSG SYSTEMS, INC. AND TCI CABLE MANAGEMENT CORPORATION This Thirty Seventh Amendment (the "Amendment") is executed this 31st day of March, 2000, and is made by and between CSG Systems, Inc., a Delaware corporation ("CSG") and TCI Cable Management Corporation ("Customer"). CSG and Customer entered into a certain Restated and Amended CSG Master Subscriber Management System Agreement dated August 10, 1997, which has subsequently been amended pursuant to separately executed amendments (collectively, the "Agreement"), and now desire to 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 as follows: 1. As of the date of execution of this Amendment, the Agreement does not specify the System Sites at which Customer may use the Products or receive the Services. For clarification purposes, CSG and Customer have set forth in Attachment A hereto a list of such System Sites. Accordingly, any references to System Sites in Schedule A, C or F shall refer to the sites listed in Attachment A. If, however, Customer obtains from CSG Product licenses or additional Services for use only at certain System Sites, Customer and CSG shall agree as such in writing, in form acceptable to CSG. As applicable, Customer shall promptly notify CSG in writing (to the attention of CSG's Associate Counsel) of its intent to add or delete System Sites. THIS AMENDMENT is executed on the day and year first shown above. CSG SYSTEMS, INC. ("CSG") TCI CABLE MANAGEMENT CORPORATION ("Customer") By: /s/ Joseph T. Ruble By: /s/ Joe W.
