ITEM 1.  BUSINESS

GENERAL
 
  CSG Systems International, Inc. (the "Company" or "CSG") was formed in October
1994 and acquired all of the outstanding stock of CSG Systems, Inc. (formerly
Cable Services Group, Inc.) from First Data Corporation ("FDC") in November 1994
(the "Acquisition"). CSG Systems, Inc. had been a subsidiary or division of FDC
from 1982 until the Acquisition. 
 
  The Company's principal executive offices are located at 7887 East Belleview, 
Suite 1000, Englewood, Colorado 80111, and the telephone number at that address 
is (303) 796-2850. The Company's common stock is listed on the Nasdaq 
National Market under the symbol "CSGS".

COMPANY OVERVIEW
 
  The Company is a leading provider of customer care and billing solutions for
cable television and direct broadcast satellite ("DBS") providers, and also
serves on-line services and telecommunications providers. The Company's
products and services enable its clients to focus on their core businesses,
improve customer service, and enter new markets and operate more efficiently.
The Company offers its clients a full suite of processing and related services,
and software and professional services which automate customer care and billing
functions. These functions include set-up and activation of customer accounts,
sales support, order processing, invoice calculation, production and mailing,
management reporting, and customer analysis for target marketing. The Company's
products and services combine the reliability and high volume transaction
processing capabilities of a mainframe platform with the flexibility of
client/server architecture. The Company generated revenue of $171.8 million in
1997 compared to $132.3 million in 1996, an increase of 29.9%, and revenue grew
at a compound annual growth rate of 27.0% over the three year period ended
December 31, 1997.
 
  The Company has established a leading presence by developing strategic
relationships with major participants in the cable television and DBS
industries, and derived approximately three-quarters of its revenues in 1997
from the U.S. cable television industry. The Company's U.S. clients include six
of the ten largest cable television service providers, four Regional Bell
Operating Companies ("RBOCs") for video services, two DBS service providers,
and an on-line services company. During 1997, the Company derived approximately
77% of its total revenues from processing and related services. At December 31,
1997, the Company was servicing client sites having an aggregate of 21.1
million customers in the U.S., compared to 19.2 million customers serviced as
of December 31, 1996. The Company has contracts to convert a significant number
of additional customers to its customer care and billing systems. From January
1, 1998 through February 28, 1998, the Company converted and processed
approximately 1.6 million additional customers on its systems.
 
  The convergence of communications markets and growing competition are
increasing the complexity and cost of managing the interaction between
communications service providers and their customers. Customer care and billing
systems coordinate all aspects of the customer's interaction with a service
provider, from initial set-up and activation, to service activity monitoring,
through billing and accounts receivable management. The growing complexity of
communications services and the manner in which they are packaged and priced,
has created increased demand for customer care and billing systems which
deliver enhanced flexibility and functionality. Because of the significant
level of technological expertise and capital resources required to develop and
implement such systems successfully, the majority of cable television, DBS, and
wireless service providers have elected to outsource customer care and billing.
 
  The Company entered into a 15-year contract (the "TCI Contract") with a Tele-
Communications, Inc. ("TCI") affiliate during the third quarter of 1997.
Subject to performance of the Company's obligations, the contract provides for:
(i) the Company to be TCI's exclusive provider of customer care and billing
solutions for analog and digital cable television, on-line services, wireline
residential telephony, and print and mail services; and (ii) minimum financial
commitments by TCI based on a minimum of 13.0 million TCI cable television
customers, of which approximately 4 million were on the Company's system prior
to the execution of the TCI Contract.
 
                                       3

  The Company expanded its operations internationally through the acquisition
of Bytel Limited ("Bytel") in June 1996. Bytel, established in 1992, is the
leading provider of customer care and billing solutions in the United Kingdom
to providers of combined cable television and telephony (business and
residential) services. Bytel serves a total of approximately 1 million
customers, approximately 75% of whom receive multiple services. During 1997,
the Company derived 9.6% of its total revenues from international sources.
 
GROWTH STRATEGY
 
  The Company's growth strategy is designed to provide revenue and profit
growth. The key elements of the strategy include:
 
  Expand Core Processing Business. The Company will continue to leverage its
investment and expertise in high-volume transaction processing to expand its
processing business. The processing business provides highly predictable
recurring revenues through multi-year contracts with a client base which
includes leading communications service providers in growing markets. The
Company increased the number of customers processed on its systems from 16.4
million as of December 31, 1994 to 21.1 million as of December 31, 1997, with
approximately 11 million additional customers under contract to be converted.
The Company's approach to customer care and billing provides a full suite of
products and services which combines the reliability and high volume
transaction processing capabilities of a mainframe platform with the
flexibility of client/server architecture.
 
  Introduce New Products and Services. The Company has a significant installed
client base to which it can sell additional value-added products and services.
Through the introduction of new client/server software applications, including
Advanced Customer Service Representative(TM) ("ACSR"(TM)), Enhanced Statement
Presentation(TM) ("ESP"(TM)) and CSG VantagePoint(TM), the Company has increased
its annual revenue per customer from $5.30 in 1994 to $7.73 in 1997. The Company
will continue to develop software applications, which will enhance and extend
the functionality of its customer care and billing solution and also provide
additional revenue opportunities.
 
  Enter New Markets. As communications markets converge, the Company's products
and services can facilitate efficient entry into new markets by existing or new
clients. For example, as the cable television providers expand into on-line
services and telephony, the Company will continue to offer the customer care
and billing solutions necessary to meet their needs. The Company also seeks to
identify other industries, such as utilities, that with modifications to the
Company's existing technology, could be served by the Company's customer care
and billing solutions.
 
  Enhance Growth Through Focused Acquisitions. The Company follows a
disciplined approach to acquire assets and businesses which provide the
technology and technical personnel to expedite the Company's product
development efforts, provide complementary products or services, or provide
access to new markets or clients.
 
  Continue Technology Leadership. The Company believes that its technology in
customer care and billing solutions gives communications service providers a
competitive advantage. The Company's continuing investment in research and
development is designed to position the Company to meet the growing and
evolving needs of existing and potential clients.
 
  Pursue International Opportunities. The Company believes that privatization
and deregulation in international markets presents new opportunities for
customer care and billing providers. In the United Kingdom, Bytel is the
leading provider of customer care and billing solutions to providers of
combined cable television and telephony (business and residential) services.
The Company expects to complete major project enhancements to Bytel's customer
care and billing system in 1998, including UNIX/Oracle platform conversion and
internationalization to accommodate various currencies, postal codes, and tax
requirements. The Company intends to market the product in European and other
international markets.

CSG SERVICES AND PRODUCTS
 
  The Company serves the converging communications markets through processing
and related services (offered in a service bureau environment) and software
products and professional services.
 
 Processing and Related Services
 
  The Company's primary processing and related services products are as
follows:
 
  Communications Control System and Related Products. Communications Control
System(TM) ("CCS" (TM)) is a customer care and billing system used primarily by
clients in the cable television and DBS industries. The primary purpose of CCS
is to provide the Company's clients with a complete set of customer management
and information services, including enrollment of new customers, event ordering,
scheduling of on-site installations and repairs, customer service support, and
billing. Designed for high volume transaction processing, CCS is offered as a
service bureau application, with clients accessing it through a
telecommunications network via terminals or personal computers at the clients'
location. The Company maintains all records and files for its clients and
performs statement processing and invoice mailing in conjunction with the other
services. The Company provides a wide variety of ancillary services to its
clients, such as service activation, pay-per-view, and archival of data. The CCS
system offers flexible reporting capabilities and interfaces with all major
vendors so clients can utilize pay-per-view, automated number identification and
audio response units. For the years ended December 31, 1995, 1996, and 1997, the
Company generated 84.7%, 77.3%, and 76.7%, respectively, of its total revenues
from CCS and related services and software products.
 
  Financial Services. The Company offers a comprehensive set of processing-
related financial services (e.g., credit card processing, electronic funds
transfer, automated refund check processing, and electronic lockbox service)
designed to improve operational efficiencies by saving employee time and
improving a client's cash flow.
 
  Statement Printing and Mailing. The Company provides statement printing and
mailing services for all of its CCS clients. The Company also provides
specialized printing and mailing for clients not on the Company's customer
care and billing systems. The Company's statement processing center handles
multiple billing cycles for all clients and, during the year ended December
31, 1997 printed and mailed in excess of 21 million pieces per month on
average. The Company offers its clients a number of marketing services based
on information contained in the client's CCS customer database, including
insert design and printing, direct mailing, and data downloads used to support
market research.
 
  Enhanced Statement Presentation. ESP enables clients to customize all
aspects of their billing statements, create a unique identity, and build a
stronger relationship with the customer. ESP enables clients to send
specialized messages or coupons on monthly bills, depending on buying
patterns, payment histories, and other customer specific information.
 
 Software Products and Professional Services
 
  The Company's currently available software products include the following:
 
  Advanced Customer Service Representative and related modules. ACSR is a
client/server, front end to the CCS product that employs a graphical user
interface. ACSR features include a customizable reference library, e-mail, a
news bulletin board, and pull-down items and an icon toolbar that makes
navigation easy. ACSR runs on a local area network at the client's service
center, which is connected to the CCS mainframe. Customer Interaction Tracking
(TM) ("CIT"(TM)) is an add-on module to ACSR which allows customer service
representatives, using a relational database management system, to track and
recall automatically all interaction and activity with customers. ACSR
provides clients with an integrated solution for billing and servicing
telephony and on-line services customers independently or in conjunction with
other business lines.
 
  CSG Vantage. CSG Vantage(TM) is a software product used in conjunction with
CCS. Data is maintained by the Company in a specially designed database which is
updated daily from CCS. Clients are provided with an ad hoc query and reporting
tool that runs on local personal computers to access detailed information stored
in the database allowing clients to analyze operations, identify trends, and
target markets.
 
  CSG VantagePoint. CSG VantagePoint is the Company's data marketing and
management warehouse product which can be licensed for use at the client's own
facility. The database structure facilitates the analysis and identifications
of the demographic, psychographic and transactional parameters of the client
data. The
 
                                       5

product offers a modular approach, enabling a provider to select the
applications most appropriate for its individual situation.
 
  CSG.web. CSG.web(TM) provides clients with a secure World Wide Web ("WWW")
interactive interface for their customers. CSG.web enables customers to
upgrade their services, order pay-per-view events, view information regarding
available services, and view and pay their statements on-line via the WWW.
CSG.web is incorporated into the client's web site, running on its web server,
which is connected to the CCS mainframe.
 
  SMS. Bytel's SMS product provides a full range of business support software

tariffing, provisioning and activation, cable service activation, collections,
equipment inventory, call record processing, rating, dispatch, trouble tickets,

codes, and tax requirements.
 
  Professional Services. The Company offers professional services to address
the needs of clients through specialized services such as technical
consulting, custom application development, business process definition,

SOFTWARE MAINTENANCE AND SUPPORT
 
  The Company provides maintenance services on all of its software products.
Maintenance fees are typically based upon a percentage of the software license
fee paid by the customer. Virtually all new software customers purchase
maintenance services. Maintenance services are typically sold for multi-year
periods in conjunction with the software license. Maintenance services
typically consist of enhancements and updates to the software products, as
well as telephone support concerning the operation of the programs.
 
SOFTWARE PRODUCTS IN DEVELOPMENT
 
  The following software products are in development and not currently
available:
 
  Acquisition of SUMMITrak Assets. In September 1997, and contemporaneously
with the effectiveness of the TCI Contract, the Company acquired certain
SUMMITrak (TM) assets, a client/server, open systems, in-house customer care and
billing system in development. The assets purchased consisted primarily of
software, hardware, assembled workforce and intellectual property. The total
purchase price was approximately $159 million, with approximately $105 million
allocated to purchased research and development ("R&D") and the remaining amount
allocated to long-lived assets. Purchased R&D represents R&D of software
technologies which had not reached technological feasibility as of the
acquisition date, and had no other alternative future use. Purchased R&D was
charged to operations in the fourth quarter of 1997.
 
  The Company intends to continue the development of certain software
technologies acquired from TCI and integrate such technologies into its
current products. The Company is currently developing several additional
products using the SUMMITrak next-generation, open system technologies to
increase the functionality of CCS. These products use a modern architecture
with relational databases, UNIX servers, object-oriented logic, and graphical
user interfaces, and are expected to be sold as optional add-on software
components to CCS, and include CSG Dispatch(TM), CSG TechNet(TM), Interactive 
Voice Response Services ("IVR"(TM)), and Closed Loop Inventory. CSG Dispatch
provides automated work order routing and technician assignment and provides the
dispatcher with a geographic information system (GIS)-based method for
monitoring and reassigning work orders throughout the day. CSG

TechNet is an optional add-on component to CSG Dispatch that provides two-way
data communications to the technician in the field, allowing the technician to
close work orders, send and receive messages, and perform other functions. IVR
Services allows customers to make pay-per-view orders and perform other
transactions over the telephone by interacting with an IVR. Closed Loop
Inventory provides a method for tracking client equipment in the field,
primarily the set top boxes that are used in the field for communication
services. The Company expects to complete these products by the end of 1998 and
early 1999.
 
  Usage Handling System. The Usage Handling System ("UHS"(TM)) is a highly
scalable, highly configurable rating component that allows usage events such as
telephone calls and data connection events to be rated and billed via CCS.
 
  CSG Phoenix. The Company is developing CSG Phoenix(TM), a customer care and
billing system which uses a three-tier client/server architecture, composed of
the graphical user interface, the business logic, and the database. CSG Phoenix
uses an open systems approach including a UNIX operating system, C and C++
programming languages, APIs, and object-oriented design, analysis, and
implementation. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Non-Recurring Charges."
 
 
CLIENTS
 
  The Company's business is concentrated in the U.S. within the cable
television, DBS and on-line services industries. Based on 1997 revenues, all of
the Company's largest clients are cable television providers except Echostar
(DBS) and Prodigy Services Company (on-line services), and all of such clients
are in the U.S. except Telewest and Bell Cable Media. The Company's largest
clients based on 1997 revenues are listed below in alphabetical order:
 
    Bell Cable Media                     Prodigy Services Company
    Century Communications Corporation   TCI and TCI Satellite Entertainment,
    Comcast Corporation                   Inc.
    Echostar                             Telewest
    Falcon Cable TV                      Time Warner
                                         US West Media Group
 
  During the years ended December 31, 1995, 1996, and 1997, revenues from TCI
represented approximately 25.2%, 25.9% and 32.9% of total revenues, and
revenues from Time Warner Cable and its affiliated companies ("Time Warner")
represented approximately 27.9%, 22.9% and 20.1% of total revenues,
respectively. The Company has separate processing agreements with multiple
affiliates of Time Warner and provides products and services to them under
separately negotiated and executed contracts. 
 
CLIENT AND PRODUCT SUPPORT
 
  The Company's clients typically rely on CSG for ongoing support and training
needs relating to the Company's products. The Company has a multi-level support
environment for its clients. The Company's Product Support Center operates 24
hours a day, seven days a week. Clients call an 800 number and through an
automated voice response unit, direct their calls to the specific product
support representative who can answer their question. In addition, each client
has a dedicated account manager. This professional helps clients resolve
strategic and business issues. The Company has a full-time training staff and
conducts ongoing training sessions both in the field and at its training
facility located in Omaha, Nebraska.
 
SALES AND MARKETING
 
  The Company has assembled a direct sales and sales support organization. The
market for the Company's products and services is concentrated, with each
existing and potential client representing multiple revenue opportunities. The
Company has organized its sales efforts around senior level account managers
who are
 
                                       7

<PAGE>
 
responsible for new revenues and renewal of existing contracts within an
account. Account managers are supported by direct sales and sales support
personnel who are experienced in the various products and services that the
Company provides.
 
FDC DATA PROCESSING FACILITY
 
  The Company outsources to FDC data processing and related services required
for operation of the CCS system. The Company's proprietary software is run in
FDC's facility to obtain the necessary mainframe computer capacity and support
without making the substantial capital investment that would be necessary for
the Company to provide this service internally. The Company's clients are
connected to the FDC facility through a combination of private and
commercially provided networks. FDC provides the services to the Company
pursuant to a five year agreement which is scheduled to expire December 31,
2001. The Company believes it could obtain data processing services from
alternative sources, if necessary.
 
RESEARCH AND DEVELOPMENT
 
  The Company's product development efforts are focused on developing new
products and improving existing products. The Company believes that the timely
development of new applications and enhancements is essential to maintaining
its competitive position in the marketplace.
 
  The Company's total R & D expense, excluding purchased
R & D, was $14.3 million, $20.2 million, and $22.6 million
for the years ended December 31, 1995, 1996, and 1997, or 14.8%, 15.3%, and
13.2% of total revenues, respectively. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
COMPETITION
 
  The market for customer care and billing systems in the converging
communications industries is highly competitive. The Company competes with
both independent providers and in-house developers of customer management
systems. The Company believes its most significant competitors are USCS
International, Inc. ("USCS"), Cincinnati Bell Information Systems ("CBIS"),
and in-house systems. As the Company enters additional market segments, it
expects to encounter additional competitors. Some of the Company's actual and
potential competitors have substantially greater financial, marketing and
technological resources than the Company.
 
  The Company believes that the principal competitive factors in its markets
include time to market, flexibility and architecture of the system, breadth of
product features, product quality, customer service and support, quality of
R & D effort, and price. 
 
PROPRIETARY RIGHTS AND LICENSES
 
  The Company relies on a combination of trade secrets and copyright laws,
patents, license agreements, non-disclosure and other contractual provisions,
and technical measures to protect its proprietary rights. The Company
distributes its products under service and software license agreements which
typically grant clients non-exclusive licenses to use the products. Use of the
software products is restricted and subject to terms and conditions
prohibiting unauthorized reproduction or transfer of the software products.
The Company also seeks to protect the source code of its software as a trade
secret and as a copyrighted work. Despite these precautions, there can be no
assurance that misappropriation of the Company's software products and
technology will not occur. The Company also incorporates via licenses or
reselling arrangements a variety of third party technology and software
products that provide specialized functionality within its own products and
services. Although the Company believes that its product and service offerings
conform with such arrangements and do not infringe upon the intellectual
property rights of the other parties to such arrangements or of other third
parties, there can be no assurance that any third parties will not assert
contractual or infringement claims against the Company.
 
EMPLOYEES
 
  As of December 31, 1997, the Company had a total of 1,141 employees, an
increase of 249 from December 31, 1996. The Company's success is dependent
upon its ability to attract and retain qualified employees. None of the
Company's employees are subject to a collective bargaining agreement. The
Company believes that its relations with its employees are good.

          The Company believes that its facilities are adequate for its current
needs and that additional suitable space will be available as required. The
Company also believes that it will be able to extend leases as they terminate.
See Note 9 to the Company's Consolidated Financial Statements for information
regarding the Company's obligations under its facilities leases.

ITEM 3.   LEGAL PROCEEDINGS

          In October 1996, a former senior vice president of CSG Systems filed a
lawsuit against the Company and certain of its officers in the District Court of
Arapahoe County, Colorado. The suit claims that certain amendments to stock
agreements between the plaintiff and the Company are unenforceable, and that the
plaintiff's rights were otherwise violated in connection with those amendments.
The plaintiff is seeking damages of approximately $1.8 million, and in addition,
seeks to have such damages trebled under certain Colorado statutes that the
plaintiff claims are applicable. The Company denies the allegations and intends
to vigorously defend the lawsuit at all stages. The trial is currently scheduled
to commence in July 1998.

          From time to time, the Company is involved in litigation relating to
claims arising out of its operations in the normal course of business. In the
opinion of the Company's management, after consultation with outside counsel,
the Company is not presently a party to any material pending or threatened legal
proceedings except as further described above.

ITEM 4.   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

          A special meeting of the stockholders of the Company was held on
December 16, 1997. At that meeting, the stockholders were asked to approve an

the Board on September 3, 1997, which would increase the number of shares of
Common Stock available under the 1996 Plan from 2,400,000 shares to 4,000,000
shares. 17,950,626 votes were cast for the amendment, 3,291,713 were cast
against it, and there were 74,486 abstentions.

(1) The Company was formed in October 1994 and acquired all of the outstanding
    shares of CSG Systems, Inc., formerly Cable Services Group, Inc., from 
    FDC on November 30, 1994 (the "Acquisition"). The Company did not have any
    substantive operations prior to the Acquisition. The Acquisition was
    accounted for as a purchase and the Company's Consolidated Financial
    Statements (the "Consolidated Financial Statements") since the date of the
    Acquisition are presented on the new basis of accounting established for the
    purchased assets and liabilities. The Company incurred certain acquisition-
    related charges as a result of the Acquisition. These acquisition-related
    charges included an immediate charge of $40.9 million as of the Acquisition
    date for purchased research and development and recurring, periodic
    amortization of acquired software, client contracts and related intangibles,
    noncompete agreement and goodwill, and stock-based employee compensation.
(2) On June 28, 1996, the Company acquired all of the outstanding shares of
    Bytel. The acquisition was accounted for using the purchase method of
    accounting.
(3) The Company completed an initial public offering ("IPO") of its Common
    Stock in March 1996. The Company sold 3,335,000 shares of Common Stock
    resulting in net proceeds to the Company of $44.8 million. Such proceeds
    were used to repay long-term debt of $40.3 million and to pay accrued
    dividends of $4.5 million on Redeemable Convertible Preferred Stock
    ("Preferred Stock"). As of the closing of the IPO, all of the Preferred
    Stock was automatically converted into 17,999,998 shares of Common Stock.
    The Company incurred an extraordinary loss of $1.3 million for the write-
    off of deferred financing costs attributable to the portion of the long-
    term debt repaid.
(4) Contemporaneously with the Acquisition, the Company purchased from FDC all
    of the outstanding capital stock of Anasazi Inc. ("Anasazi"). On August 31,
    1995, the Company completed a substantial divestiture of Anasazi, resulting
    in the Company owning less than 20% of Anasazi. In September 1997, the
    Company sold its remaining ownership interest in Anasazi for $8.6 million
    in cash. The Company accounted for its ownership in Anasazi as discontinued
    operations after its acquisition in 1994.
(5) In September 1997, the Company purchased certain SUMMITrak assets from TCI
    and entered into the TCI Contract. The total purchase price for the assets
    was approximately $159 million, $106.0 million of which was paid in cash at
    closing, with approximately $105 million allocated to purchased research
    and development with the remaining amount allocated to long-lived assets.
    See Note 4 to the Consolidated Financial Statements for a description of
    the balance of the purchase price. The purchased research and development
    was charged to operations in the fourth quarter of 1997. The Company
    financed the asset acquisition with a $150.0 million term credit facility
    (the "Term Credit Facility"), of which $27.5 million was used to retire the
    Company's previously outstanding debt, resulting in an extraordinary loss
    of $.6 million for the write-off of deferred financing costs attributable
    to such debt.
(6) During the fourth quarter of 1997, the Company recorded a non-recurring
    charge of $11.7 million to reduce certain CSG Phoenix assets to their net
    realizable value as of December 31, 1997.
(7) During the fourth quarter of 1997, the Company recorded a non-recurring
    charge of $4.7 million for the impairment of certain intangible assets
    related to software systems which the Company decided to no longer market
    and support.
(8) Net loss per common share and the shares used in the per share computation
    have been computed on the basis described in Note 2 to the Consolidated
    Financial Statements.

ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

GENERAL
 
  Acquisition of CSG Systems, Inc. The Company was formed in October 1994 and
acquired all of the outstanding stock of CSG Systems, Inc. (formerly Cable
Services Group, Inc.) from FDC in November 1994 (the "Acquisition"). CSG
Systems, Inc. had been a subsidiary or division of FDC from 1982 until the
Acquisition. The Company acquired CSG Systems, Inc. for approximately $137
million in cash and accounted for the Acquisition using the purchase method of
accounting. See Note 3 to the Consolidated Financial Statements for additional
discussion.
 
  Public Offering. The Company completed the IPO in March 1996. The Company
sold 3,335,000 shares of Common Stock at a price of $15 per share, resulting
in net proceeds to the Company, after deducting the underwriting discount and
offering expenses, of approximately $44.8 million. The net proceeds from the
IPO were used to repay long-term debt of $40.3 million and to pay accrued
dividends of $4.5 million on Preferred Stock. As of the closing of the IPO,
all of the 8,999,999 outstanding shares of Preferred Stock were automatically
converted into 17,999,998 shares of Common Stock and all accrued dividends
were paid. See Notes 5 and 6 to the Consolidated Financial Statements for
additional information regarding the Company's Preferred Stock and long-term
debt.
 
  Acquisition of Bytel Limited. On June 28, 1996, the Company acquired all of
the outstanding shares of Bytel for $3.1 million in cash and assumption of
certain liabilities of $1.6 million. The acquisition was accounted for using
the purchase method of accounting. The cost in excess of the fair value of the
net tangible assets acquired of $4.2 million was allocated to goodwill and is
being amortized over seven years on a straight-line basis. The Consolidated
Financial Statements include Bytel's results of operations since the
acquisition date. Bytel, established in 1992, is the leading provider of
customer care and billing solutions in the United Kingdom to providers of
combined cable television and telephony (business and residential) services.
 
  Acquisition of SUMMITrak Assets and TCI Contract. In September 1997, the
Company purchased certain SUMMITrak assets from TCI and entered into the TCI
Contract. The Company completed the accounting for these transactions in the
fourth quarter of 1997. The total purchase price was approximately $159
million, with approximately $105 million allocated to purchased research and
development ("R&D") and the remaining amount allocated to long-lived assets.
Purchased R&D represents R&D of software technologies which had not reached
technological feasibility as of the acquisition date, and had no other
alternative future use. Purchased R&D was charged to operations in the fourth
quarter of 1997. The Company financed the SUMMITrak asset acquisition with the
Term Credit Facility, of which $27.5 million was used to retire the Company's
previously outstanding debt. See Notes 4 and 6 to the Consolidated Financial
Statements for additional information regarding the SUMMITrak asset
acquisition and the related financing.
 
  The Company intends to continue the development of certain software
technologies acquired from TCI and integrate such technologies into its current
products. The Company is currently developing several additional products using
the SUMMITrak next-generation, open system technologies to increase the
functionality of CCS. These products use a modern architecture with relational
databases, UNIX servers, object-oriented logic, and graphical user interfaces,
and are expected to be sold as optional add-on software components to CCS, and
include CSG Dispatch, CSG TechNet, IVR Services, and Closed Loop Inventory. CSG
Dispatch provides automated work order routing and technician assignment and
provides the dispatcher with a geographic information system (GIS)-based method
for monitoring and reassigning work orders throughout the day. CSG TechNet is an
optional add-on component to CSG Dispatch that provides two-way data
communications to the technician in the field, allowing the technician to close
work orders, send and receive messages, and perform other functions. IVR
Services allows customers to make pay-per-view orders and perform other
transactions over the telephone by interacting with an IVR. Closed Loop
Inventory provides a method for tracking client equipment in the field,
primarily the set top boxes that are used in the field for communication
services. The Company expects to complete these products by the end of 1998 and
early 1999.

OVERVIEW
 
  The Company. The Company is a leading provider of customer care and billing
solutions for cable television and direct broadcast satellite providers, and
also serves on-line services and telecommunications providers. The Company's
products and services enable its clients to focus on their core businesses,
improve customer service, and enter new markets and operate more efficiently.
The Company offers its clients a full suite of processing and related
services, and software and professional services which automate customer care
and billing functions. These functions include set-up and activation of
customer accounts, sales support, order processing, invoice calculation,
production and mailing, management reporting, and customer analysis for target
marketing. The Company's products and services combine the reliability and
high volume transaction processing capabilities of a mainframe platform with
the flexibility of client/server architecture.
 
  Revenues. The Company's revenues are derived principally from processing and
related services, which represented 99.9%, 85.8% and 76.5% of the Company's
total revenues for the years ended December 31, 1995, 1996 and 1997,
respectively. As a result of the expected conversions in 1998 of TCI's and
other clients' customers onto the Company's customer care and billing system,
the Company expects processing and related services as a percentage of total
revenues in 1998 to increase when compared to 1997. Processing and related
services consist of processing fees, ancillary services and certain customized
print and mail services. Processing fees are typically billed based on the
number of a client's customers serviced, ancillary services are typically
billed on a per transaction basis, and customized print and mail services are
billed on a usage basis. Typically, the Company signs multi-year processing
contracts with its clients which include provisions for annual price
increases, and many of which include financial minimums. The Company's
processing and related services are derived principally from its CCS product
and services ancillary to CCS.
 
  The Company passes through to its clients the cost of postage and the cost
of communication lines between client sites and the mainframe data processing
facility. Such reimbursements of cost are netted against the expense and are
not included in total revenues.
 
  Although the Company believes that the majority of its revenues will
continue to come from processing and related services over the next several
years, the Company has developed new software products and professional
services. The software products include, among others, ACSR, ACSR Telephony,
CSG Vantage, and CSG VantagePoint. Revenue from these software products and
professional services, including revenue from the acquired software products
and related services of Bytel, were $.1 million, $18.9 million, and $40.4
million, or .1%, 14.2% and 23.5% of total revenues, for the years ended
December 31, 1995, 1996 and 1997, respectively. Software products and
professional services as a percentage of total revenues in 1998 are expected
to decrease when compared to 1997, due to the increased percentage of revenues
expected to be generated from processing and related services in 1998, as
discussed above. The Company licenses its software products under both
perpetual and multi-year term licenses. See "Business" for additional
discussion of the Company's products and services.
 
  Cost of Revenues. Direct costs for processing and related services consist
primarily of: (i) the salaries and benefits of employees involved in certain
systems and programming, client and product support, and statement production;
(ii) the cost of data processing; and (iii) statement and envelope costs. The
Company's data processing services for CCS are provided by FDC under a five-
year agreement which expires December 31, 2001. The cost of such services
provided by FDC are based on usage and/or actual costs and were $16.9 million,
$19.6 million and $19.2 million for the years ended December 31, 1995, 1996
and 1997, respectively. The amortization of acquired software, client
contracts and related intangibles relates primarily to amortization of assets
acquired in the Acquisition. The acquired software was fully amortized in
November 1997.
 
  The cost of software license and maintenance fees consists primarily of the
salaries and benefits of the systems and programming employees supporting the
Company's software products. The cost of professional services consists
primarily of the salaries and benefits of the employees performing such
services.
 
                                      14

<PAGE>
 
  Operating Expenses. R&D expense consists primarily of the salaries and
benefits of the employees involved in internal software and product
development. Software and product development costs have increased
significantly as resources have been added to develop new software products
and enhance existing products.
 
  Selling and marketing expense consists primarily of the salaries,
commissions, and benefits of those employees involved in sales and marketing
activities, as well as travel, convention, and advertising expenses.
 
  General and administrative expense consists primarily of the salaries and
benefits of management and administrative personnel and general office
administration expense. Amortization of noncompete agreements and goodwill
consists primarily of amortization of assets acquired in the Acquisition.
Stock-based employee compensation expense relates to purchases of the
Company's Common Stock by executive officers and key employees in 1994 and
1995, prior to the Company's IPO. See Notes 3 and 11 of the Consolidated
Financial Statements for additional discussion of these items.
 
  Income Taxes. Although the Company has incurred net losses for the years
ended 1995, 1996, and 1997, the Company has paid U.S. income taxes for each of
these years and expects to pay United Kingdom income taxes for 1997, due
primarily to differences in the timing of recognition of the amortization of
intangible assets for financial reporting and tax purposes. For income tax
purposes, the amortization of the intangible assets related to the Acquisition
and the charge for purchased research and development related to the SUMMITrak
asset acquisition, are principally deductible over 15 years on a straight-line
basis. Based on its current projections, the Company expects to pay U.S.
income taxes for 1998.
 
  At December 31, 1997, the Company concluded that it was more likely than not
that certain of the Company's deferred tax assets would be realized.
Accordingly, the Company has recognized a net deferred tax asset of $7.4
million. The Company has recorded a valuation allowance of approximately $61.3
million against the remaining net deferred tax assets since realization of
these future benefits is not sufficiently assured as of December 31, 1997. The
Company intends to analyze the realizability of the net deferred tax assets at
each future quarterly reporting period. The current quarterly results of
operations, as well as the Company's projected results of operations, will
determine the required valuation allowance at the end of each quarter. Based
on its current projections of operating results for 1998, the Company expects
to realize additional deferred tax assets in 1998. As a result, the Company
does not expect income tax expense for 1998 to be significant.
 
ACQUISITION CHARGES
 
  Acquisition Charges. As a result of the Acquisition, the Company has
recorded recurring, periodic amortization of acquired software, client
contracts and related intangibles, noncompete agreement, goodwill and stock-
based employee compensation (collectively, the "Acquisition Charges"). The
Acquisition Charges totaled $21.6 million, $24.4 million, and $20.7 million,
for the years ended December 31, 1995, 1996 and 1997, respectively. See Notes
3 and 11 to the Consolidated Financial Statements for additional information
regarding the Acquisition and the Acquisition Charges.
 
  Discontinued Operations. Contemporaneously with the Acquisition, the Company
purchased from FDC all of the outstanding shares of Anasazi for $6.0 million
cash. Anasazi provides central reservation systems and services for the
hospitality and travel industries. The Company accounted for its ownership in
Anasazi as discontinued operations after its acquisition in 1994. On August
31, 1995, the Company completed a substantial divestiture of Anasazi,
resulting in the Company owning less than 20% of Anasazi. As a result, the
$3.1 million loss from discontinued operations included in the Company's 1995
financial statements consists of the net losses of Anasazi from January 1 to
August 31, 1995. Anasazi's results of operations subsequent to August 31, 1995
are not included in the Company's results of operations as the Company
accounted for its investment in Anasazi under the cost method subsequent to
August 31, 1995. In September 1997, the Company sold its remaining interest in
Anasazi for $8.6 million in cash. The loss of $.7 million in August 1995 and
the gain of $7.9 million in September 1997 relate to the Company's substantial
and then final disposition of its ownership interest in Anasazi. See Note 10
to the Consolidated Financial Statements for additional information regarding
Anasazi.
 
                                      15

<PAGE>
 
NON-RECURRING CHARGES
 
  Charge for Purchased Research and Development. During the fourth quarter of
1997, the Company recorded a charge of $105.5 million related primarily to the
portion of the SUMMITrak asset acquisition purchase price allocated to
purchased research and development related to software technologies which had
not reached technological feasibility and had no other alternative future use
as of the acquisition date. See Note 4 to the Consolidated Financial
Statements for additional discussion.
 
  Impairment of Capitalized Software Development Costs. During the fourth
quarter of 1997, the Company recorded a charge of $11.7 million related to
certain CSG Phoenix assets. After the consideration of multiple factors and
events, consisting primarily of an increase in demand for the Company's
outsourced processing services and previously announced delays in the delivery
of CSG Phoenix, such assets were reduced to their estimated net realizable
value as of December 31, 1997. The charge primarily includes previously
capitalized internal development costs and purchased software incorporated
into the product. The Company intends to continue its development of CSG
Phoenix. See Notes 2 and 13 to the Consolidated Financial Statements for
additional discussion.
 
  Impairment of Intangible Assets. During the fourth quarter of 1997, the
Company recorded a charge of $4.7 million for the impairment of certain
intangible assets related to software systems which the Company has decided to
no longer market and support. This impairment charge relates principally to
the Company's CableMAX product. CableMAX is a personal computer-based customer
management system targeted at smaller cable systems of 2,500 customers or
less. During the fourth quarter of 1997, the Company decided not to invest the
resources necessary to make the software year 2000 compliant, resulting in the
impairment of the CableMAX intangible assets. See Note 2 to the Consolidated
Financial Statements for additional discussion.
 
  Extraordinary Loss From Early Extinguishment Of Debt. In September 1997, the
Company retired its outstanding bank indebtedness of $27.5 million in
conjunction with obtaining financing for the SUMMITrak asset acquisition. Upon
repayment of the outstanding debt, the Company recorded an extraordinary loss
of $.6 million for the write-off of deferred financing costs. In March 1996,
the Company recorded an extraordinary charge of $1.3 million for the write-off
of deferred financing costs related to repayment of $40.3 million of long-term
debt with proceeds from the IPO. See Note 6 to the Consolidated Financial
Statements for additional discussion.
 
ADJUSTED RESULTS OF OPERATIONS
 
  Impact of Acquisition Charges and Non-recurring Charges on Earnings. As
discussed above, the Company has incurred Acquisition Charges and non-
recurring charges in each of the last three years. The total of these charges
was $25.4 million, $25.7 million and $135.3 million for the years ended
December 31, 1995, 1996 and 1997, respectively. The Company's adjusted results
of operations excluding these items is shown in the following table. In
addition to the exclusion of these expenses from the calculation, the adjusted
results of operations were computed using an effective income tax rate of
38.0%, and outstanding shares on a diluted basis.

TWELVE MONTHS ENDED DECEMBER 31, 1997 COMPARED TO THE TWELVE MONTHS ENDED
DECEMBER 31, 1996
 
  Revenues. Total revenues increased $39.5 million, or 29.9%, to $171.8
million in 1997, from $132.3 million in 1996, due primarily to increased
revenues from the Company's processing and related services, as well as
increased revenues from software and related product sales and professional
consulting services.
 
  Revenues from processing and related services increased $18.0 million, or
15.8%, to $131.4 million in 1997, from $113.4 million in 1996, due primarily
to an increase in the number of customers of the Company's clients which were
serviced by the Company and increased revenue per customer. Customers serviced
as of December 31, 1997 and 1996 were 21.1 million and 19.2 million,
respectively, an increase of 10.1%. The increase in the number of customers
serviced was due primarily to internal customer growth experienced by existing
clients and the addition of new clients. Revenue per customer increased due to
price increases included in client contracts and increased usage of ancillary
services by existing clients.
 
  Revenues from software and related product sales and professional consulting
services increased $21.5 million, or 114.1%, to $40.4 million in 1997, from
$18.9 million in 1996. This increase relates to the introduction of the
Company's new software products, primarily ACSR and CSG VantagePoint, and
professional consulting services in early 1996 with continued expansion
throughout 1996 and 1997, and the inclusion of revenues from Bytel's
operations for all of 1997, whereas six months of revenues for Bytel were
included for 1996.
 
  Amortization of Acquired Software. Amortization of acquired software
decreased $.4 million, or 3.7%, to $10.6 million in 1997, from $11.0 million
in 1996, due primarily to acquired software from the Acquisition becoming
fully amortized as of November 30, 1997. See Note 3 to the Consolidated
Financial Statements for additional discussion of the Acquisition and its
impact on operations.
 
  Amortization of Client Contracts and Related Intangibles. Amortization of
client contracts and related intangibles increased $.2 million, or 4.9%, to
$4.3 million in 1997, from $4.1 million in 1996 due primarily to amortization
from the TCI Contract executed in September 1997.
 
  Gross Margin. Gross margin increased $23.7 million, or 40.9%, to $81.8
million in 1997, from $58.1 million in 1996, due primarily to revenue growth.
The gross margin as a percentage of total revenues increased to 47.6% in 1997,
compared to 43.9% in 1996. The increase in the gross margin as a percentage of
total revenues is due primarily to: (i) a favorable change in revenue mix
which included more higher-margined software products; (ii) the increase in
revenues while the overall amount of amortization of acquired software and the
amortization of client contracts and related intangibles remained relatively
constant; and (iii) the increase in processing and related services revenue
per customer while controlling the cost of delivering such services.
 
  Research and Development Expense. Research and development expense increased
$2.4 million, or 11.8%, to $22.6 million in 1997, from $20.2 million in 1996.
As a percentage of total revenues, R&D expense decreased to 13.2% in 1997 from
15.3% in 1996. The Company capitalized software development costs, related
primarily to CSG Phoenix, of approximately $9.7 million during 1997, which
consisted of $8.4 million of internal development costs and $1.3 million of
purchased software. The Company capitalized software development costs,
related primarily to CSG Phoenix, ACSR Telephony and CSG VantagePoint, of
approximately $3.1 million in 1996, which consisted of $2.5 million of
internal development costs and $.6 million of purchased software. As a result,
total R&D expenditures (i.e., the total R&D costs expensed, plus the
capitalized internal development costs) for 1997 and 1996 were $31.0 million,
or 18.0% of total revenues, and $22.7 million, or 17.2% of total revenues,
respectively. The overall increase in R&D expenditures is due primarily to
continued efforts on several products which are in development and
enhancements of the Company's existing products. The increased R&D
expenditures consist primarily of increases in salaries, benefits and other
programming-related expenses.
 
  Selling and Marketing Expense. Selling and marketing expense increased $2.0
million, or 24.2%, to $10.2 million in 1997, from $8.2 million in 1996. As a
percentage of total revenues, selling and marketing expense decreased to 5.9%
in 1997, compared to 6.2% in 1996. The increase in expense is due primarily to
continued
 
                                      18

<PAGE>
 
growth of the Company's direct sales force throughout 1996 and most of 1997.
The Company began building a new direct sales force in mid-1995 and continued
to expand its sales force until reaching its present level as of the end of
1997.
 
  General and Administrative Expense. General and administrative ("G&A")
expense increased $5.7 million, or 41.5%, to $19.4 million in 1997, from $13.7
million in 1996. As a percentage of total revenues, G&A expense increased to
11.3% in 1997, from 10.4% in 1996. The increase in expense relates primarily
to: (i) the continued expansion of the Company's management team and related
administrative staff, added throughout 1996 and 1997, to support the Company's
overall growth; (ii) an increase in facility costs to support employee growth,
including the cost of relocating the Company's corporate headquarters; (iii)
expenses of $.7 million related to the closing of the TCI Contract and the
SUMMITrak asset purchase agreement; and (iv) the inclusion of G&A expenses
from Bytel's operations for all of 1997, whereas six months of G&A expenses
for Bytel were included for 1996.
 
  Amortization of Noncompete Agreements and Goodwill. Amortization of
noncompete agreements and goodwill increased $.5 million, or 8.4%, to $6.9
million in 1997, from $6.4 million in 1996. The increase in expense relates to
amortization of goodwill from the Bytel acquisition and amortization of an
additional noncompete agreement executed in April 1996.
 
  Stock-Based Employee Compensation. During 1995 and 1994, the Company sold
Common Stock to executive officers and key employees pursuant to performance
stock agreements and recorded deferred compensation of $5.8 million related to
these purchases. Prior to the completion of the IPO, the deferred compensation
was being recognized as stock-based employee compensation expense on a
straight-line basis from the time the shares were purchased through November
30, 2001, as the shares became vested as of this date. Upon completion of the
IPO, shares owned by certain executive officers of the Company became fully
vested. In addition, the vesting for the remaining performance stock shares
decreased to 20.0% annually over a five-year period. As a result,
approximately $3.2 million of stock-based employee compensation expense was
recorded when the IPO was completed in March 1996. Amortization of the stock-
based deferred compensation subsequent to 1997 will be approximately $.3
million per year. See Note 11 to the Consolidated Financial Statements for
additional discussion.
 
  Depreciation Expense. Depreciation expense increased $1.8 million, or 34.4%,
to $6.9 million in 1997, from $5.1 million in 1996, with the increase
attributed to capital expenditures throughout 1996 and 1997 in support of the
overall growth of the Company.
 
  Operating income (loss). Operating loss was $106.5 million for 1997,
compared to operating income of $.8 million for 1996. The change between years
relates primarily to the non-recurring charges recorded in the fourth quarter
of 1997, as discussed above.
 
  Interest Expense. Interest expense increased $1.1 million, or 27.7%, to $5.3
million in 1997, from $4.2 million in 1996, with the increase attributable
primarily to new debt incurred under the Term Credit Facility. This increase
was partially offset by the effects of: (i) scheduled principal payments on
the Company's long-term debt; (ii) the retirement of $40.3 million of long-
term debt with the proceeds from the IPO in March 1996; and (iii) a decrease
in the Company's interest rate spread on LIBOR, as a result of the Company
favorably amending its long-term credit facility in April 1996.
 
TWELVE MONTHS ENDED DECEMBER 31, 1996 COMPARED TO THE TWELVE MONTHS ENDED
DECEMBER 31, 1995
 
  Revenues. Total revenues increased $35.9 million, or 37.2%, to $132.3
million in 1996, from $96.4 million in 1995, due primarily to increased
revenues from the Company's processing and related services, as well as
increased revenues from software and related product sales and professional
consulting services.
 
  Revenues from processing and related services increased $17.1 million, or
17.7%, to $113.4 million in 1996, from $96.3 million in 1995, due primarily to
an increase in the number of customers of the Company's clients
 
                                      19

<PAGE>
 
which were serviced by the Company and increased revenue per customer.
Customers serviced as of December 31, 1996 and 1995 were 19.2 million and 18.0
million, respectively, an increase of 6.9%. The increase in the number of
customers serviced was due primarily to internal customer growth experienced
by existing clients and the addition of new clients. Revenue per customer
increased due to annual price increases included in client contracts and
increased usage of ancillary services by existing clients.
 
  Revenue from the Company's new software products introduced in early 1996,
primarily ACSR and CSG VantagePoint, and professional services, as well as
revenue from the software products and related services of Bytel for six
months in 1996, were $18.9 million in 1996 compared to $.1 million in 1995.
 
  Gross Margin. Gross margin increased $23.5 million, or 67.6%, to $58.1
million in 1996, from $34.6 million in 1995, due primarily to revenue growth.
The gross margin as a percentage of total revenues increased to 43.9% in 1996,
compared to 36.0% in 1995. The increase in the gross margin as a percentage of
total revenues is due primarily to: (i) a favorable change in revenue mix
which included more higher-margined software products; (ii) the increase in
revenues while the overall amount of amortization of acquired software and the
amortization of client contracts and related intangibles remained relatively
constant; and (iii) the increase in processing and related services revenue
per customer while controlling the cost of delivering such services.
 
  Research and Development Expense. Research and development expense increased
$5.9 million, or 41.5%, to $20.2 million in 1996, from $14.3 million in 1995.
As a percentage of total revenues, R&D expense increased to 15.3% in 1996 from
14.8% in 1995. The Company capitalized software development costs, related
primarily to CSG Phoenix, ACSR Telephony and CSG VantagePoint, of
approximately $3.1 million in 1996, which consisted of $2.5 million of
internal development costs and $.6 million of purchased software. No software
development costs were capitalized during 1995. As a result, total R&D
expenditures (i.e., the total R&D costs expensed, plus the capitalized
internal development costs) for 1996 were $22.7 million, or 17.2% of total
revenues. The overall increase in R&D expenditures is due primarily to
continued efforts on several products which are in development and
enhancements of the Company's existing products. The increased R&D
expenditures consist primarily of increases in salaries, benefits, and other
programming-related expenses.
 
  Selling and Marketing Expense. Selling and marketing expense increased $4.4
million, or 117.9%, to $8.2 million in 1996, from $3.8 million in 1995. As a
percentage of total revenues, selling and marketing expense increased to 6.2%
in 1996, from 3.9% in 1995. The increase in expense is due primarily to a
realignment of the Company's sales force. Subsequent to the Acquisition, a
substantial portion of the previous sales force was terminated during the
three months ended March 31, 1995, and senior management focused on sales
responsibilities in 1995. The Company began building a new direct sales force
in mid-1995 and continued to expand its sales force throughout 1996.
 
  General and Administrative Expense. G&A expense increased $2.3 million, or
20.1%, to $13.7 million in 1996, from $11.4 million in 1995. The increase in
expense relates primarily to the development of the Company's management team
and to related administrative staff added during 1996 and 1995 to support the
Company's growth. As a percentage of total revenues, G&A expense decreased to
10.4% in 1996, from 11.8% in 1995.
 
  Amortization of Noncompete Agreements and Goodwill. Amortization of
noncompete agreements and goodwill increased $.7 million, or 12.5%, to $6.4
million in 1996, from $5.7 million in 1995. The increase in expense relates to
amortization of goodwill from the Bytel acquisition and amortization of an
additional noncompete agreement acquired in April 1996.
 
  Stock-Based Employee Compensation. Stock-based employee compensation expense
for the years ended December 31, 1996 and 1995, of $3.6 million and $.8
million, respectively, relates to purchases of the Company's Common Stock by
executive officers and key employees. The increase between years relates to
the accelerated vesting for certain employees effective as of the closing of
the IPO in March 1996, as discussed above.

  Depreciation Expense. Depreciation expense decreased $.6 million, or 10.0%,
to $5.1 million in 1996, from $5.7 million in 1995, with the decrease
attributed to certain fixed assets becoming fully depreciated in 1995.
 
  Operating income (loss). Operating income was $.8 million for 1996, compared
to an operating loss of $7.0 million for 1995. The change between years
relates to the factors discussed above.
 
  Interest Expense. Interest expense decreased $4.9 million, or 54.0%, to $4.2
million in 1996, from $9.1 million in 1995. The decrease was attributable to:
(i) scheduled principal payments on the Company's long-term debt; (ii) the
retirement of $40.3 million of long-term debt with proceeds from the IPO in
March 1996; and (iii) a decrease in the Company's interest rate spread on
LIBOR, as a result of the Company favorably amending its long-term credit
facility in April 1996.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  As of December 31, 1997, the Company's principal sources of liquidity
included cash and cash equivalents of $20.4 million. The Company's working
capital as of December 31, 1996 and 1997 was $4.4 million and $3.5 million,
respectively. The Company also has a revolving credit facility with a bank in
the amount of $40.0 million, of which there were no borrowings outstanding as
of December 31, 1997. The Company's ability to borrow under the revolving
credit facility is subject to maintenance of certain levels of eligible
receivables. At December 31, 1997, $30.6 million of the $40.0 million
revolving credit facility was available to the Company based on the current
level of eligible receivables. The revolving credit facility expires in
September 2002.
 
  The Company's net cash flows from operating activities for the years ended
December 31, 1995, 1996 and 1997 were $11.8 million, $29.1 million and $31.4
million, respectively. The increase of $2.3 million, or 7.8%, in 1997 over
1996 relates to a $9.2 million increase in net cash flows from operations,
offset by an increase in the net change in operating assets and liabilities of
$6.9 million. The increase of $17.3 million, or 147.3%, in 1996 over 1995
relates to a $14.4 million increase in net cash flows from operations and a
decrease in the net change in operating assets and liabilities of $2.9
million.
 
  The Company's net cash flows used in investing activities totaled $117.4
million in 1997, compared to $14.7 million in 1996, an increase in $102.7
million. The increase between years relates primarily to the cash payments of
$106.5 million for the SUMMITrak assets acquired in September 1997 and an
increase of $6.6 million in capitalized software development costs between
years, with these increases offset by proceeds of $8.6 million from the final
disposition of Anasazi. The Company's net cash flow used in investing
activities totaled $5.3 million in 1995. The increase of $9.4 million between
1995 and 1996 relates primarily to: (i) an increase of $3.0 million in 1996
for capital expenditures to support Company growth; (ii) acquisitions of
business in 1996 of $4.9 million, which relates primarily to Bytel; and (iii)
$3.5 million in capitalized software development costs in 1996. These
increases were offset by $2.0 million of cash received from Anasazi for a note
receivable in January 1996.
 
  The Company's net cash flows from financing activities was $100.7 million in
1997, compared to a use of net cash flows of $12.1 million in 1996, an
increase of $112.8 million. The significant increase between years relates
primarily to the net change in the Company's long-term debt between years. In
1997, the Company generated $150.0 million from a new debt agreement entered
into primarily to fund the SUMMITrak asset acquisition, and repaid long-term
debt of $47.5 million, which included: (i) $5.0 million of scheduled payments
on the previous debt agreement; (ii) $27.5 million of existing debt which was
refinanced as part of the new debt agreement; and (iii) an optional prepayment
of $15.0 million on the new debt, which was made in December 1997. The net
cash flows used in financing activities totaled $9.5 million for 1995. The
increase of $2.6 million between 1995 and 1996 relates primarily to an
increase in scheduled debt payments in 1995 over 1996. In addition, the
Company sold 3,335,000 shares of Common Stock at an initial public offering
price of $15 per share, resulting in net proceeds to the Company, after
deducting underwriting discounts and offering expenses, of approximately $44.8
million. The net proceeds from the IPO were used to repay long-term debt of
$40.3 million and to pay accrued dividends of $4.5 million on Preferred Stock.
As of the closing of the IPO in March
 
                                      21

<PAGE>
 
1996, all of the 8,999,999 outstanding shares of the Preferred Stock were
automatically converted into 17,999,998 shares of Common Stock, at which time
the accrued dividends became payable.
 
  The Company financed the SUMMITrak asset acquisition in September 1997 with
the $150.0 million Term Credit Facility, of which $27.5 million was used to
retire the Company's previously outstanding debt. Interest rates under the new
agreement are chosen at the option of the Company and are based on the LIBOR
rate or the prime rate, plus an additional percentage spread, with the spread
dependent upon the Company's leverage ratio. For the period from September
1997 through December 31, 1997, the spread on the LIBOR rate and prime rate
was 1.75% and .5%, respectively. Based on the Company's leverage ratio as of
December 31, 1997, the spread on the LIBOR rate and prime rate was reduced to
1.0% and 0%, respectively, effective January 1, 1998. As a result of this
additional debt, the Company expects interest expense to increase in 1998 when
compared to 1997. See Note 6 to the Consolidated Financial Statements for
additional discussion of the Term Credit Facility.
 
  The Term Credit Facility requires maintenance of certain financial ratios
and contains other restrictive covenants, including restrictions on payment of
dividends, a fixed charge coverage ratio, a leverage ratio and restrictions on
capital expenditures. As of December 31, 1997, the Company was in compliance
with all covenants. The payment of dividends or other types of distributions
on any class of the Company's stock is restricted unless the Company's
leverage ratio, as defined in the Term Credit Facility, is less than 1.50. As
of December 31, 1997, the leverage ratio was 2.80.
 
  The purchase price for the SUMMITrak assets acquired in September 1997
includes up to $26.0 million in conversion incentive payments. The timing of
the conversion incentive payments is based upon the achievement of certain
milestones by TCI and the Company, as specified in the SUMMITrak asset
acquisition agreement. The milestones are based principally upon the number of
TCI's customers converted to, and the total number of TCI customers processed
on, the Company's customer care and billing system. Based on the conversions
scheduled as of December 31, 1997, the Company expects to pay $17.8 million to
TCI in 1998 and $8.2 million in 1999.
 
  The Company believes that cash generated from operations, together with the
current cash and cash equivalents and the amount available under the revolving
credit facility, will be sufficient to meet its anticipated cash requirements
for operations (including research and development expenditures), income
taxes, debt service, conversion incentive payments and capital expenditures
for both its short and long-term purposes.
 
YEAR 2000
 
  In 1995, the Company began efforts to identify and assess any issues
associated with its software's ability to properly utilize dates and process
data beyond the year 2000. The Company recognizes that the failure to properly
and timely address issues surrounding the year 2000 could have a material
impact on its operations, and as a result it appointed a project team to
undertake a Company-wide study to determine the full scope and related costs
to the Company of ensuring that its systems can continue to meet the Company's
internal needs, as well as those of its customers. The Company's year 2000
project team is communicating with vendors and customers to coordinate year
2000 conversion and will provide the Company's management with a report that
includes an estimate of costs to be incurred by the Company in properly
addressing this issue. The Company currently believes that it will be able to
effectively mitigate risks associated with the year 2000 and that its Company-
wide year 2000 project will be substantially complete by the end of the fourth
quarter of 1998. The Company does not expect the costs to make its systems
year 2000 compliant to be material to its financial condition or results of
operations.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors of
CSG Systems International, Inc.:
 
  We have audited the accompanying consolidated balance sheets of CSG Systems
International, Inc. (a Delaware corporation) and Subsidiaries as of December
31, 1996 and 1997, and the related consolidated statements of operations,
stockholders' equity and cash flows for each of the three years in the period
ended December 31, 1997. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of CSG Systems International,
Inc. and Subsidiaries as of December 31, 1996 and 1997, and the results of
their operations and their cash flows for each of the three years in the
period ended December 31, 1997, in conformity with generally accepted
accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                        
1. GENERAL
 
  CSG Systems International, Inc. (the "Company" or "CSG"), a Delaware
corporation, was formed on October 17, 1994, for the purpose of acquiring all
of the outstanding shares of Cable Services Group, Inc. from First Data
Corporation ("FDC"). The Company acquired all of the outstanding shares of
Cable Services Group, Inc. on November 30, 1994 (the "Acquisition") (Note 3).
Subsequent to the Acquisition, Cable Services Group, Inc.'s name was changed
to CSG Systems, Inc. ("CSG Systems"). The Company did not have any substantive
operations prior to the acquisition of Cable Services Group, Inc.
Contemporaneously with the Acquisition, the Company purchased all of the
outstanding shares of Anasazi Inc. ("Anasazi") (Note 10). On June 28, 1996,
the Company purchased all of the outstanding shares of Bytel Limited ("Bytel")
(Note 3).
 
  The Company is a leading provider of customer care and billing solutions for
cable television and direct broadcast satellite providers, and also serves on-
line services and telecommunications providers. The Company's products and
services enable its clients to focus on their core businesses, improve
customer service, and enter new markets and operate more efficiently. The
Company offers its clients a full suite of processing and related services,
and software and professional services which automate customer care and
billing functions. These functions include set-up and activation of customer
accounts, sales support, order processing, invoice calculation, production and
mailing, management reporting, and customer analysis for target marketing. The
Company's products and services combine the reliability and high volume
transaction processing capabilities of a mainframe platform with the
flexibility of client/server architecture.
 
  The Company operates in one business segment, generating 88.8 percent, 76.6
percent, and 73.1 percent of its total revenues from U.S. cable television
providers during the years ended December 31, 1995, 1996 and 1997,
respectively. The Company generated zero percent, 8.1 percent, and 9.6 percent
of its total revenues from sources outside the U.S., primarily in Europe,
during the years ended December 31, 1995, 1996 and 1997, respectively.
 
  The Company derived approximately 84.8 percent, 77.3 percent and 76.7
percent of its total revenues in the years ended December 31, 1995, 1996 and
1997, respectively, from its core product, Communications Control System
("CCS") and related products and ancillary services.
 
  The Company has two significant clients which, in the aggregate, represented
approximately 53.1 percent, 48.8 percent, and 53.0 percent of total revenues
for the years ended December 31, 1995, 1996 and 1997, respectively. The
largest single client contributed approximately 27.9 percent, 25.9 percent and
32.9 percent of total revenues for the years ended December 31, 1995, 1996 and
1997, respectively.
 
  The Company completed an initial public offering ("IPO") of its Common Stock
in March 1996. The Company sold 3,335,000 shares of Common Stock at an initial
public offering price of $15 per share, resulting in net proceeds to the
Company, after deducting underwriting discounts and offering expenses, of
approximately $44.8 million. As of the closing of the IPO, all of the
8,999,999 outstanding shares of Redeemable Convertible Series A Preferred
Stock ("Preferred Stock") were automatically converted into 17,999,998 shares
of Common Stock. The Company used IPO proceeds to repay $40.3 million of
outstanding bank indebtedness (Note 6) and to pay $4.5 million of accrued
dividends on the Preferred Stock (Note 5).
 
  In September 1997, the Company acquired certain SUMMITrak assets from Tele-
Communications, Inc. ("TCI") and entered into a 15-year processing contract
with TCI (Note 4).
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Principles of Consolidation
 
  The accompanying consolidated financial statements include the accounts of
the Company and CSG Systems for all periods presented and the accounts of
Bytel since June 28, 1996. All material intercompany accounts and transactions
have been eliminated.

 Use of Estimates in Preparation of Consolidated Financial Statements
 
  The preparation of the consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the
consolidated financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
 Cash and Cash Equivalents
 
  The Company considers all highly liquid investments with original maturities
of three months or less to be cash equivalents.
 
 Revenue Recognition
 
  Processing and related services are recognized as the services are
performed. Processing fees are typically billed based on the number of
client's customers serviced, ancillary services are typically billed on a per
transaction basis, and certain customized print and mail services are billed
on a usage basis. Software license fees consist of both one-time perpetual
licenses and term licenses. Perpetual license fees are typically recognized
upon delivery, depending upon the nature and extent of the installation and/or
customization services, if any, to be provided by the Company. Term license
fees and maintenance fees are recognized ratably over the contract term.
Professional services are recognized as the related services are performed.
 
  In October 1997, the Accounting Standards Executive Committee of the
American Institute of Certified Public Accountants issued Statement of
Position 97-2, "Software Revenue Recognition" ("SOP 97-2"). SOP 97-2 provides
guidance on applying generally accepted accounting principles in recognizing
revenue on software transactions. SOP 97-2 is effective for software
transactions entered into by the Company beginning in fiscal year 1998. The
Company believes that its current revenue recognition accounting policies are
in compliance with SOP 97-2.
 
  Payments received for revenues not yet recognized are reflected as deferred
revenue in the accompanying consolidated balance sheets.
 
 Property and Equipment
 
  Property and equipment are recorded at cost and are depreciated over their
estimated useful lives ranging from two to ten years. Depreciation is computed
using the straight-line method for financial reporting purposes. Depreciation
for income tax purposes is computed using accelerated methods.
 
  Property and equipment at December 31 consists of the following (in
thousands):

 Realizability of Long-Lived and Intangible Assets
 
  The Company continually evaluates whether events and circumstances have
occurred that indicate the remaining estimated useful life of long-lived and
intangible assets may warrant revision or that the remaining balance of these
assets may not be recoverable. The Company evaluates the recoverability of its
long-lived and intangible assets by measuring the carrying amount of the
assets against the estimated undiscounted future cash flows associated with
them. At the time such evaluations indicate that the future undiscounted cash
flows of certain long-lived and intangibles assets are not sufficient to
recover the carrying value of such assets, the assets are adjusted to their
estimated fair values.
 
 Software
 
  Software at December 31 consists of the following (in thousands):

</TABLE>
 
  Acquired software resulted from the Acquisition and is stated at cost.
Amortization expense related to acquired software for the years ended December
31, 1995, 1996 and 1997 was $11.0 million, $11.0 million and $10.6 million,
respectively.
 
  The Company capitalizes certain software development costs when the
resulting products reach technological feasibility and begins amortization of
such costs upon the general availability of the products for licensing. The
Company capitalized costs of $3.1 million and $9.7 million for 1996 and 1997,
which included $2.5 million and $8.4 million of internal development costs and
$0.6 million and $1.3 million of purchased software, respectively.
 
  Amortization of internally developed software and acquired software costs
begins when the products are available for general release to clients and is
computed separately for each product as the greater of a) the ratio of current
gross revenue for a product to the total of current and anticipated gross
revenue for the product or b) the straight-line method over the remaining
estimated economic life of the product. Currently, estimated lives of two to
five years are used in the calculation of amortization. Amortization expense
related to capitalized software development costs for the years ended December
31, 1995, 1996 and 1997 was zero, $0.01 million and $0.6 million,
respectively.
 
  The Company continually evaluates the carrying value of its unamortized
capitalized software development costs. The amount by which the unamortized
capitalized costs exceed the net realizable value of the asset is expensed.
During the fourth quarter of 1997, the Company recorded a charge of $11.7
million related to certain CSG Phoenix(TM) assets. After the consideration of
multiple factors and events, consisting primarily of an increase in demand for
the Company's outsourced processing services and previously announced delays
on the delivery of CSG Phoenix, such assets were reduced to their estimated
net realizable value as of December 31, 1997. The charge primarily includes
previously capitalized internal development costs and purchased software
incorporated into the product.

  Noncompete agreements and goodwill as of December 31 are as follows (in

</TABLE>
 
  The noncompete agreements resulted from acquisitions and are being amortized
on a straight-line basis over the terms of the agreements, ranging from three
to five years. Goodwill resulted from acquisitions and is being amortized over
seven to ten years on a straight-line basis (Note 3).
 
  During the fourth quarter of 1997, the Company recorded a charge of $4.7
million for the impairment of certain intangible assets related to software
systems which the Company has decided to no longer market and support. This
impairment charge relates principally to the Company's CableMAX product.
CableMAX is a personal computer based customer management system that is
targeted at smaller cable systems of 2,500 customers or less. During the
fourth quarter of 1997, the Company decided not to invest the resources
necessary to make the software year 2000 compliant, resulting in the
impairment to the CableMAX intangible assets. The estimated fair value of the
CableMAX intangible assets was based upon an analysis of expected future cash
flows and a quoted purchase price from an independent buyer.
 
 Client Contracts and Related Intangibles
 
  Client contracts and client conversion methodologies from the Acquisition
are being amortized over their estimated lives of five and three years,
respectively. The value assigned to the TCI processing contract (Note 4) is
being amortized over the 15-year life of the contract in proportion to the
guaranteed processing revenues under the contract. As of December 31, 1996 and
1997, accumulated amortization for client contracts and related intangibles
was $8.5 million and $12.8 million, respectively.
 
 Customer Deposits
 
  The Company requires postage and communications deposits from its clients
based on contractual arrangements. These amounts are reflected as current
liabilities regardless of the contract period.
 
 Financial Instruments with Market Risk and Concentrations of Credit Risk
 
  In the normal course of business, the Company is exposed to credit risk
resulting from the possibility that a loss may occur from the failure of
another party to perform according to the terms of a contract. The Company
regularly monitors credit risk exposures and takes steps to mitigate the
likelihood of these exposures resulting in a loss. The primary counterparties
to the Company's accounts receivable and sources of the Company's revenues
consist of cable television providers throughout the United States. The
Company generally does not require collateral or other security to support
accounts receivable.
 
 Financial Instruments
 
  The Company's balance sheet financial instruments as of December 31, 1996
and 1997 include cash and cash equivalents, accounts receivable, accounts
payable, conversion incentive payments, and long-term debt.
 
                                      32

                        CSG SYSTEMS INTERNATIONAL, INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
Because of their short maturities, the carrying amounts of cash equivalents,
accounts receivable, accounts payable, and conversion incentive payments
approximate fair value. The carrying amount of the Company's long-term debt
(including current maturities) approximates fair value due to its variable
interest rates.
 
  In December 1997, the Company entered into a three-year interest rate collar
with a major bank to manage its risk from its variable rate long-term debt.
The underlying notional amount covered by the collar agreement is $75.0
million as of December 31, 1997, and decreases over the three-year term in
relation to the scheduled principal payments on the long-term debt. Any
payment on the 4.9 percent (LIBOR) interest rate floor, or receipt on the 7.5
percent (LIBOR) interest rate cap component of the collar, would be recognized
as additional interest expense or as a reduction to interest expense,
respectively, in the period incurred. There are no amounts due or receivable
under this agreement as of December 31, 1997, and the agreement had no effect
on the Company's interest expense for 1997. The fair value of the collar
agreement at December 31, 1997, based on a quoted market price, was not
significant.
 
 Translation of Foreign Currency
 
  The Company's foreign subsidiary, Bytel, uses the British pound as its
functional currency. Bytel's assets and liabilities are translated into U.S.
dollars at the exchange rates in effect at the balance sheet date. Revenues
and expenses are translated at the average rates of exchange prevailing during
the period. Translation gains and losses are included as a component of
stockholders' equity. Transaction gains and losses related to intercompany
accounts are not material and are included in the determination of net loss.
 
 Net Loss Per Common Share
 
  In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, "Earnings Per Share" ("SFAS 128"),
which specifies the computation, presentation and disclosure requirements for
earnings per share ("EPS"). SFAS 128 is effective for periods ending after
December 15, 1997, and requires retroactive restatement of EPS for all prior
periods presented. The statement replaces the previous "primary earnings per
share" computation with a "basic earnings per share" and redefines the
"diluted earnings per share" computation. Basic EPS is computed by dividing
income attributable to Common Stockholders by the weighted average number of
common shares outstanding during the period. Diluted EPS is consistent with
the calculation of basic EPS while giving effect to any dilutive potential
common shares outstanding during the period.
 
  A reconciliation of the net loss attributable to common stockholders in
total dollars (in thousands) and on a per share basis is as follows:

  In previously reported periods, the Company followed Staff Accounting
Bulletin ("SAB") No. 83 in calculating EPS for the periods prior to the
Company's IPO. Pursuant to SAB No. 83, all preferred and common stock and
options outstanding for periods prior to the IPO had been treated as if they
were outstanding for all periods presented, including periods in which the
effect was antidilutive. SAB No. 98, released in February 1998, requires that
SFAS 128 now be followed in determining the outstanding shares for purposes of
calculating EPS for all periods. As a result, the Company has restated its EPS
(and all other per share computations) for the periods prior to and including
the IPO following the guidelines of SFAS 128. The changes in the weighted
average common shares and the EPS are as follows:

 Bytel Limited
 
  On June 28, 1996, the Company acquired all of the outstanding shares of
Bytel for approximately $3.1 million in cash and assumption of certain
liabilities of $1.6 million (the "Bytel Acquisition"). The Bytel Acquisition

4. SUMMITRAK ASSET ACQUISITION
 
  On August 10, 1997, the Company signed a 15-year exclusive contract with a
TCI affiliate to consolidate 13.0 million TCI customers onto the Company's
customer care and billing system (the "TCI Contract"). On August 10, 1997, the
Company also entered into an agreement with TCI affiliates to acquire certain
SUMMITrak assets, a client/server, open systems, in-house customer care and
billing system in development (the "SUMMITrak Acquisition"). The SUMMITrak
assets purchased consisted primarily of software, hardware, assembled
workforce and intellectual property. Both the SUMMITrak Acquisition and the
TCI Contract closed and became effective September 19, 1997. The purchase
price for the SUMMITrak Acquisition was determined as follows (in thousands):

</TABLE>
 
  The conversion incentive payments represent payments to TCI to i) incent TCI
to timely convert its customers to the Company's system, and ii) reimburse TCI
for the cost of converting to the Company's system. TCI will receive a monthly
payment $0.15 per customer for the first 24 months after the customer is
converted to the Company's system (total of $3.60 per customer), up to a total
of $14.0 million. A total of 3.89 million TCI customers converted to the
Company's systems equates to the $14.0 million. TCI will be paid an additional
$12.0 million when the Company processes a total of 13.0 million TCI customers
on its system. Based on the conversions scheduled as of December 31, 1997, the
Company expects to pay TCI $17.8 million and $8.2 million in 1998 and 1999,
respectively.
 
  The Company granted 1.5 million warrants to TCI as part of the overall
purchase price. The warrants have a five-year life with a $24 per share
exercise price. The fair value of the warrants included in the purchase price
was estimated as of the date of the grant using the Black-Scholes pricing
model. TCI will be able to exercise 1.0 million of the warrants when the
Company processes a total of 13.0 million TCI customers on its customer care
and billing system. The remaining 0.5 million warrants are exercisable at
various increments as additional TCI customers are converted to the Company's
systems. The total 1.5 million warrants are exercisable when the total number
of TCI customers processed on the Company's systems reaches 14.25 million.
 
  The Company has included the conversion incentive payments and the estimated
fair value of the warrants in the overall purchase price as the Company
believes that such consideration is assured beyond a reasonable doubt as i)
TCI currently has the necessary customers under its control to meet the
milestones described above, ii) the Company believes it has the means to
timely convert the necessary customers to its systems to meet the milestones
described above, iii) both the Company and TCI are financially incented to
timely convert the necessary customers to the Company's system to meet the
milestones described above, and iv) TCI's minimum financial commitments are
based on a minimum of 13.0 million customers.
 
  The Company engaged an independent party to assist in the allocation of the
purchase price to the assets acquired. The Company allocated the purchase
price as follows (in thousands):

</TABLE>
 
  In conjunction with the Acquisition (Note 3), the Company sold for cash
8,999,999 shares of Preferred Stock with a par value of $.01 per share. Total
proceeds, net of issuance costs of $0.4 million, were $59.1 million ($6.56 per
share). The holders of Preferred Stock were entitled to vote on all matters
and were entitled to the number of votes equivalent to the number of shares of
Common Stock into which such shares of Preferred Stock were converted. All
Preferred Stock converted into 17,999,998 shares of the Company's Common Stock
upon completion of the IPO in March 1996.
 
  Prior to completion of the IPO, the holders of the outstanding shares of
Preferred Stock were entitled to receive cumulative annual dividends of $.3967
per share, prior to any dividends being paid on the Company's Common Stock.
Upon completion of the IPO and the resulting conversion into Common Stock, the
Company paid dividends on the Preferred Stock of $4.5 million.
 
  Prior to completion of the IPO, the Company was required to redeem Preferred
Stock on November 30, 2005. The redemption price was payable in cash and was
equal to $6.61 per share plus any accrued and unpaid dividends. The excess of
the redemption value over the carrying value was being accreted through
periodic charges to accumulated deficit over the life of the issue.
 
6. DEBT
 
  The Acquisition discussed in Note 3 was partially funded with debt placed
through a $100.0 million debt agreement with a bank (the "1994 Debt"). The
1994 Debt consisted of term loans of $95.0 million, and a revolving credit
facility in the amount of $5.0 million. The Company made early payments on the
1994 Debt of $2.4 million and $2.0 million in 1995 and 1996, respectively. In
conjunction with the IPO, the Company
 
                                      37

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
refinanced its 1994 Debt with its bank in April 1996. The Company repaid
approximately $40.6 million of the outstanding 1994 Debt, principally with IPO
proceeds. The remaining balance of the 1994 Debt was refinanced with a single
$40.0 million term note with the bank (the "1996 Debt"). In conjunction with
this refinancing, the Company recorded an extraordinary loss of $1.3 million
for the write-off of deferred financing costs. The Company did not recognize
any income tax benefit related to the extraordinary loss. Under the 1996 Debt
agreement, the Company retained its $5.0 million revolving credit facility.
The Company paid an annual commitment fee of .375 percent on its unused
portion of the revolving credit facility. Interest rates for the 1994 and 1996
Debt were based on an adjusted LIBOR rate or the bank's prime rate and were
chosen at the option of the Company.
 
  In conjunction with the SUMMITrak Acquisition, the Company entered into a
$190.0 million debt agreement with a bank in September 1997 (the "1997 Debt"),
which consists of a $150.0 million term facility (the "Term Credit Facility")
and a $40.0 million revolving credit facility. The proceeds from the Term
Credit Facility were used to pay the $106.0 million cash purchase price for
the SUMMITrak assets, retire the Company's existing 1996 Debt of $27.5
million, and pay transaction costs of $3.4 million. The remaining proceeds
were used for general corporate purposes. In conjunction with this
refinancing, the Company recorded an extraordinary loss of $0.6 million for
the write-off of deferred financing costs. The Company did not recognize any
income tax benefit related to the extraordinary loss. In December 1997, the
Company made an optional principal payment on the Term Credit Facility of
$15.0 million.
 
  Interest rates for the 1997 Debt, including the term and revolving credit
facilities, are chosen at the option of the Company and are based on the LIBOR
rate or the prime rate, plus an additional percentage spread, with the spread
dependent upon the Company's leverage ratio. For the period from September
1997 through December 31, 1997, the spread on the LIBOR rate and prime rate
was 1.75% and 0.5%, respectively. Based on the Company's leverage ratio as of
December 31, 1997, the spread on the LIBOR rate and prime rate was reduced to
1.0% and 0%, respectively, effective January 1, 1998. As required by the 1997
Debt agreement, the Company entered into an interest rate collar agreement in
December 1997 to manage its risk from the variable rate features of the 1997
Debt agreement (Note 2).
 
  The 1997 Debt agreement is collateralized by all of the Company's assets and
the stock of its subsidiaries. The 1997 Debt agreement requires maintenance of
certain financial ratios and contains other restrictive covenants, including
restrictions on payment of dividends, a fixed charge coverage ratio, a
leverage ratio, and restrictions on capital expenditures. As of December 31,
1997, the Company was in compliance with all covenants. The payment of
dividends or other types of distributions on any class of the Company's stock
is restricted unless the Company's leverage ratio, as defined in the 1997 Debt
agreement, is under 1.50. As of December 31, 1997, the leverage ratio was
2.80.
 
  Long-term debt as of December 31 consists of the following (in thousands):

  There were no borrowings made on the revolving credit facilities during the
years ended December 31, 1995, 1996 and 1997. Under the 1997 Debt agreement,
the Company pays an annual commitment fee on the used portion of the revolving
credit facility, based upon the Company's leverage ratio. For the period from
September 1997 through December 31, 1997, the fee was .375 percent. The
Company's ability to borrow under the current revolving credit facility is
subject to maintenance of certain levels of eligible receivables. At December
31, 1997, $30.6 million of the $40.0 million revolving credit facility was
available to the Company based on the level of eligible receivables.
 
  As of December 31, 1996 and 1997, unamortized deferred financing costs were
$0.9 million and $2.9 million, respectively. Deferred financing costs are
amortized to interest expense over the related term of the debt agreement
using a method which approximates the effective interest rate method. Interest
expense for the years ended December 31, 1995, 1996 and 1997, includes
amortization of deferred financing costs of approximately $0.9 million, $0.6
million, and $0.5 million, respectively.

7. INCOME TAXES
 
  The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109 ("SFAS 109"), "Accounting for Income
Taxes." SFAS 109 is an asset and liability approach which requires the
recognition of deferred tax assets and liabilities for the expected future tax
consequences of events which have been recognized in the Company's
Consolidated Financial Statements or tax returns. In estimating future tax
consequences, SFAS 109 generally considers all expected future events other
than enactment of or changes in the tax law or rates.
 
  Income tax provision (benefit) consists of the following (in thousands):

  As part of the Bytel Acquisition, the Company acquired certain net deferred
tax assets and established a valuation allowance of approximately $1.0 million
against those net deferred tax assets as of the acquisition date.
 
  At December 31, 1997, management evaluated its recent operating results, as
well as projections for 1998 and concluded that it was more likely than not
that certain of the deferred tax assets would be realized. Accordingly, the
Company has recognized a deferred tax asset of $7.4 million. The Company has
recorded a valuation allowance against the remaining deferred tax assets since
realization of these future benefits is not sufficiently assured as of
December 31, 1997.

8. EMPLOYEE RETIREMENT BENEFIT PLANS
 
 Defined Benefit Retirement Plan
 
  Effective December 1, 1994, as part of the Acquisition, the Company
established a replacement plan for certain former employees of FDC which
transferred their service credit to CSG. No new participants were allowed to
enter this plan after December 1, 1994. Benefits under the plan are based on
years of service and the employees' compensation during employment.
Contributions to the plan are determined by an independent actuary on the
basis of periodic valuations using the projected unit cost method. The
Company's general funding policy is to contribute annually the maximum amount
that can be deducted for income tax purposes. The periodic pension expense for
the years ended December 31, 1995, 1996 and 1997, was $0.2 million each year.
The net pension liability recognized in the accompanying consolidated balance
sheets as of December 31, 1996 and 1997 is $0.2 million and $0.3 million,
respectively.
 
 Incentive Savings Plan
 
  The Company sponsors a defined contribution plan covering substantially all
employees of the Company. Participants may contribute up to 15 percent of
their annual wages, subject to certain limitations, as pretax, salary deferral
contributions. The Company makes certain matching and service related
contributions to the plan. The Company's matching and service related
contributions for the years ended December 31, 1995, 1996 and 1997, were
approximately $1.3 million, $1.5 million and $2.0 million, respectively.
 
 Deferred Compensation Plan
 
  The Company established a non-qualified deferred compensation plan during
1996 for certain Company executives which allows the participants to defer a
portion of their annual compensation. The Company provides a 25 percent
matching contribution of the participant's deferral, up to a maximum of $6,250
per year. The Company also credits the participant's deferred account with a
specified rate of return on an annual basis. The Company records the
actuarially-determined present value of the obligations expected to be paid
under the plan. As of December 31, 1996 and 1997, the Company has recorded a
liability for this obligation of $0.1 million and $0.6 million, respectively.
The Company's expense for this plan for the years ended December 31, 1996 and
1997, which includes Company contributions and interest expense, was $0.02
million and $0.1 million, respectively. The plan is unfunded.
 
9. COMMITMENTS AND CONTINGENCIES
 
 Operating Leases
 
  The Company leases certain office and production facilities under operating
leases which run through 2007. Future aggregate minimum lease payments under
these agreements for the years ending December 31, including a lease entered
into subsequent to December 31, 1997, are as follows (in thousands):

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  Total rent expense for the years ended December 31, 1995, 1996 and 1997, was
approximately $1.8 million, $1.9 million and $3.4 million, respectively.
 
 Service Agreements
 
  The Company has service agreements with FDC and subsidiaries for data
processing services, communication charges and other related services. FDC
provides data processing and related services required for the operation of
the Company's CCS System.
 
  Prior to 1997, the Company was charged a usage-base fee per customer for
data processing and related services. The other services were charged based on
usage and/or actual costs. Effective January 1, 1997, the Company renegotiated
its services agreement with FDC and its subsidiaries. The new agreement
expires December 31, 2001, and is cancelable at the Company's option with a)
notice of six months any time after January 1, 2000, and b) payment of a
termination fee equal to 20 percent of the fees paid in the twelve months
preceding the notification of termination. Under the new agreement, the
Company is charged based on usage and/or actual costs, and is subject to
certain limitations as to the amount of increases or decreases in usage
between years. The total amount paid under the service agreements for the
years ended December 31, 1995, 1996 and 1997, was approximately $16.9 million,
$19.6 million and $19.2 million, respectively. The Company believes it could
obtain data processing services from alternative sources, if necessary.
 
 Legal Proceedings
 
  In December 1996, CSG settled claims for indemnification against FDC arising
from CSG's acquisition from FDC of CSG Systems. The claims related to certain
patents held by Ronald A. Katz Technology Licensing Partnership L.P. ("RAKTL")
which allegedly were infringed by the use of certain CSG products. The terms
of the settlement were not material to CSG. In connection with the settlement,
CSG entered into a non-exclusive patent license agreement with RAKTL, the
terms of which are not expected by CSG to have a material effect on its
business or future results of operations.
 
  In October 1996, a former senior vice president of CSG Systems filed a
lawsuit against the Company and certain of its officers in the District Court
of Arapahoe County, Colorado. The suit claims that certain amendments to stock
agreements between the plaintiff and the Company are unenforceable, and that
the plaintiff's rights were otherwise violated in connection with those
amendments. The plaintiff is seeking damages of approximately $1.8 million,
and in addition, seeks to have such damages trebled under certain Colorado
statutes that the plaintiff claims are applicable. The Company denies the
allegations and intends to vigorously defend the lawsuit at all stages. The
trial is currently scheduled to commence in July 1998.
 
  In addition, from time to time, the Company is involved in other litigation
relating to claims arising out of its operations in the normal course of
business. In the opinion of the Company's management, after consultation with
outside legal counsel, the ultimate dispositions of such matters will not have
a materially adverse effect on the Company's consolidated financial position
or results of operations.
 
10. DISCONTINUED OPERATIONS
 
  Contemporaneously with the Acquisition, the Company purchased all of the
outstanding shares of Anasazi on November 30, 1994, for $6 million in cash.
Anasazi provides central reservation systems and services for the hospitality
and travel industry. On August 31, 1995, the company completed a tax-free
reorganization of Anasazi. Stockholders of the Company purchased a controlling
interest in Anasazi as part of the reorganization. As part of the
reorganization, the Company received $2.0 million cash, surrendered all of its
ownership rights in Anasazi's Common Stock and forgave a portion of a note
receivable from Anasazi. In return for such

consideration, the Company received a $2.7 million note receivable and shares
of convertible preferred stock representing less than a 20 percent ownership
interest in Anasazi. In January 1996, the Company received a $2.0 million
principal payment on this note, reducing the principal balance of the note to
$0.7 million. In June 1996, the Company converted the remaining $0.7 million
note balance into convertible preferred stock and stock warrants of Anasazi.
In September 1997, the Company sold its remaining interest in Anasazi for $8.6
million cash.
 
  The Company accounted for its ownership in Anasazi as discontinued
operations after its acquisition in 1994. As a result, the loss from
discontinued operations included in the Company's Consolidated Financial
Statements consists of the net losses of Anasazi prior to September 1, 1995.
The loss of $0.7 million in August 1995, and the gain of $7.9 million in
September 1997 relates to the Company's partial and then final disposition of
its ownership interest in Anasazi. Revenues from Anasazi's operations for the
eight months ended August 31, 1995 were $5.8 million. The Company did not
recognize any income tax benefit or provision related to the loss or gain from
discontinued operations.

shares were originally scheduled to be released from the repurchase option not
later than November 30, 2001. Upon completion of the IPO, these shares were no
longer subject to the repurchase option.

 Employee Stock Purchase Plan
 
  The Company reserved 1,655,500 shares of Common Stock for sale to certain
employees pursuant to the Employee Stock Purchase Plan (the "Plan"). During
the year ended December 31, 1995, the Company sold 1,655,500 shares of Common
Stock under the Plan for $1,378,000 (ranging from $.22 to $4.25 per share),
consisting of $402,000 cash and $976,000 in full recourse promissory notes. Of
the shares sold, 593,000 shares were sold under restricted stock agreements
("Restricted Stock") and 1,062,500 shares were sold under performance stock
agreements.
 
    Restricted Stock. The Restricted Stock shares are subject to certain
  conditions and restrictions as prescribed by the Restricted Stock
  agreements. The Company has the option to repurchase the shares upon
  termination of employment, for the greater of the original purchase price
  or book value, as defined, depending upon the termination circumstances.
  These shares were originally scheduled to be released from the repurchase
  option not later than November 30, 2001. Upon completion of the IPO,
  160,000 shares owned by certain executive officers were no longer subject
  to the repurchase option. In addition, the repurchase option for the
  remaining number of shares decreased to 20 percent annually over a five-
  year period, commencing on the later of an employee's hire date or November
  30, 1994. During 1996 and 1997, the Company repurchased 25,600 unvested
  shares and 44,400 unvested shares, respectively, from terminated employees.
 
    Performance Stock. The shares sold under performance stock agreements are
  subject to certain conditions and restrictions as prescribed by the
  agreements. The Company has the option to repurchase the shares for the
  original purchase price upon termination of employment. These shares were
  originally scheduled to be released from the repurchase option not later
  than November 30, 2001. Upon completion of the IPO, the repurchase option
  for these shares decreased to 20 percent annually over a five-year period,
  commencing on the later of an employee's hire date or November 30, 1994.
  During 1996 and 1997, the Company repurchased 80,000 unvested shares and
  60,150 unvested shares, respectively, from terminated employees.
 
  Certain Company employees financed a portion of their Common Stock purchases
under the Plan with full recourse promissory notes. The notes accrue interest
at seven percent annually and have terms of approximately five years. As of
December 31, 1996 and 1997, the outstanding balance of the promissory notes is
approximately $861,000 and $685,000, respectively, and is reflected as a
component of stockholders' equity.
 
 Stock-Based Employee Compensation Expense
 
  The structure of the performance stock agreements required "variable"
accounting for the related shares until the performance conditions were
removed on October 19, 1995, thereby establishing a measurement date. At that
date, the Company recognized total deferred compensation of $5.8 million which
represents the difference between the price paid by the employees and the
estimated fair value of the stock at October 19, 1995. The fair value of the
stock was estimated by the Company to be $2.75 per share at that date. Prior
to the completion of the IPO, the deferred compensation was being recognized
as stock-based employee compensation expense on a straight-line basis from the
time the shares were purchased through November 30, 2001. Upon completion of
the IPO, 1,437,500 of performance stock shares owned by certain executive
officers of the Company were no longer subject to the repurchase option. In
addition, the repurchase option for the remaining performance stock shares
decreased to 20 percent annually over a five-year period, commencing on the
later of an employee's hire date or November 30, 1994. As a result,
approximately $3.2 million of stock-based employee compensation expense was
recorded in the month the IPO was completed. Stock-based employee compensation
expense for the years ended December 31, 1995, 1996 and 1997, was $0.8
million, $3.6 million and $0.4 million, respectively. Deferred compensation of
$1.2 million and $0.6 million, respectively, as of December 31, 1996 and 1997,
is reflected as a component of stockholders' equity. Amortization of the
stock-based deferred compensation subsequent to 1997 will be approximately
$0.3 million per year.

12. STOCK-BASED COMPENSATION PLANS
 
 Stock Incentive Plans
 
  During 1995, the Company adopted the Incentive Stock Plan (the "1995 Plan")
whereby 257,000 shares of the Company's Common Stock have been reserved for
issuance to eligible employees of the Company in the form of stock options.
The stock options are granted at prices set by the Board of Directors or a
Committee of the Board (the "Board"), provided the minimum exercise price is
no less than the fair market value of the Company's Common Stock at the date
of the grant. The term of the outstanding options is 10 years. The 170,400
options outstanding under the 1995 Plan at December 31, 1997, vest annually
over 5 years.
 
  During 1996, the Company adopted the 1996 Stock Incentive Plan (the "1996
Plan") whereby 2,400,000 shares of the Company's Common Stock have been
reserved for issuance to eligible employees of the Company in the form of
stock options, stock appreciation rights, performance unit awards, restricted
stock awards, or stock bonus awards. In December 1997, upon shareholder
approval, the number of shares authorized for issuance under the 1996 Plan was
increased to 4,000,000. As of December 31, 1997, 100,000, 947,150 and 810,560
options outstanding under the 1996 Plan vest annually over 3, 4 and 5 years,
respectively.
 
  During 1997, the Company adopted the Stock Option Plan for Non-Employee
Directors (the "Director Plan") whereby 100,000 shares of the Company's Common
Stock have been reserved for issuance to non-employee Directors of the Company
in the form of stock options. Stock options under the Director Plan are
granted at prices set by the Board, provided the minimum exercise price is no
less than the fair market value of the Company's Common Stock at the date of
the grant. The term of the outstanding options is 10 years. The vesting
periods of the options are determined under the discretion of the Board. The
48,000 options outstanding under the Director Plan at December 31, 1997, vest
annually over 3 years.
 
  A summary of the stock options issued under the 1996 Plan, the Director
Plan, and 1995 Plan and changes during the years ending December 31 are as
follows:

shares vesting over four and two years, respectively. These options are not
reflected in the above tables as they were granted subsequent to December 31,
1997.
 
 1996 Employee Stock Purchase Plan
 
  During 1996, the Company adopted the 1996 Employee Stock Purchase Plan
whereby 250,000 shares of the Company's Common Stock have been reserved for
sale to employees of the Company and its subsidiaries through payroll
deductions. The price for shares purchased under the plan is 85% of market
value on the last day of the purchase period. Purchases are made at the end of
each month. During 1996 and 1997, respectively, 5,753 shares and 19,659 shares
have been purchased under the plan for $83,000 ($13.07 to $17.21 per share)
and $439,000 ($14.34 to $34.00 per share).
 
 Stock-Based Compensation Plans
 
  At December 31, 1997, the Company had four stock-based compensation plans,
as described above. The Company accounts for these plans under APB Opinion No.
25, under which no compensation expense has been recognized in 1995, 1996 or
1997, except for $89,000 recognized in 1996 for 5,925 shares granted as stock
bonus awards under the 1996 Plan.
 
  Had compensation expense for the Company's four stock-based compensation
plans been based on the fair value at the grant dates for awards under those
plans consistent with the method of SFAS 123, the Company's net loss and net
loss per share attributable to common stockholders for 1995, 1996 and 1997
would approximate the pro forma amounts as follows (in thousands, except per

all years; expected lives of 4.0, 5.0, and 3.9 years; and volatility of zero
percent, 40.0 percent, and 40.0 percent. Consistent with SFAS 123, the Company
assumed zero volatility for all options granted prior to the date the Company
qualified as a public entity.
 
  The effects of applying SFAS 123 in this pro forma disclosure are not
indicative of future amounts. SFAS 123 applies only to 1995, 1996 and 1997,
and additional awards in future years are anticipated.

To the Board of Directors of

     We have audited in accordance with generally accepted auditing standards,
the consolidated financial statements of CSG Systems International, Inc. and
Subsidiaries included in this Form 10-K and have issued our report thereon dated

                       FIRST AMENDMENT TO LOAN AGREEMENT

          THIS FIRST AMENDMENT TO LOAN AGREEMENT, dated as of November 21, 1997
("Amendment"), is entered into by and among CSG SYSTEMS, INC., a Delaware
corporation ("CSG"), and CSG SYSTEMS INTERNATIONAL, INC., a Delaware corporation

Date.

3.            AMENDMENTS TO THE LOAN AGREEMENT.

              1    The definition of "Business Day" set forth in Section 1.1 is

final sentence thereof and changing the word "No" that appears following such
clause to lower case.

          9    Section 11.4(b) is amended by inserting the words "as to any
Borrowing" in the second line thereof following the words "specified in ARTICLE

          Re:  Separation Agreement and Releases

Dear Mr. Haddix:

          This is to confirm our understanding about the termination of your
employment with CSG Systems, Inc. (the "Company").  This letter (hereafter
referred to as this "Agreement") outlines the benefits you will receive, and the
legal rights you will waive, upon execution of this Agreement, and will
constitute a binding contract when executed.  You are encouraged to consult an
attorney, and to review this Agreement carefully.

          1.   DEPARTURE FROM EMPLOYMENT; FINAL PAY AND BENEFITS.  Effective on
               -------------------------------------------------               
December 31, 1997, you will cease performing your responsibilities for the
Company as President and Chief Technology Officer and will relinquish all titles
and authorities you may have with respect to the Company. You will no longer be
authorized to incur any expenses, obligations or liabilities on behalf of the
Company, and will return all Company property within your possession, including
customer lists, information, forms, formulas, plans, documents and other written
and computer materials, and copies of the same, belonging to the Company or any
of its customers. You will receive on December 26, 1997, a payroll check for
your salary through your last day of work, plus payment for your accrued but
unused vacation hours, if not already received.

The Company will withhold from these amounts the standard state and federal

          You agree that the Company's area of business is international, and
that it is reasonable to restrict your competition as described above in order
to protect the Company's legitimate business needs. In the event that you
violate any of the terms of this paragraph, the Company may withhold and/or
recover any of the severance benefits paid or agreed to be paid to you pursuant
to paragraph 2, without waiving its right to pursue any other legal or equitable
remedies, and your entitlement to such benefits shall cease and be forfeited.
The restrictions contained herein are in addition to those restrictions
contained within any separate nondisclosure, trade secrets or non-solicitation
agreements which you have signed. You agree that the provisions of any such
agreements shall remain in full force and effect, and are not merged into this
document.

          6.   VALIDITY AND SEVERABILITY.  Both you and the Company agree that 
               -------------------------     
we will not seek to defeat, or seek to have declared invalid, any provision of
this Agreement. In the event that any part of the covenants set forth in
paragraph 5 shall be held to be invalid or unenforceable, the remaining parts
thereof shall nevertheless continue to be valid and enforceable as though the
invalid and unenforceable part had not been included herein. If any provision of
such covenants shall be declared by a court of competent jurisdiction to exceed
the maximum provisions which the court deems reasonable and enforceable, such
provisions shall be deemed to be reformed to that which such court deems
reasonable and enforceable. If the court determines that no parts of the
covenants are enforceable, then you shall immediately repay to the Company all
of the payments you received pursuant to paragraph 2 of this Agreement, and the
Company's obligation to make any further payments to you pursuant to such
paragraph shall cease.

          In the event that any benefits are forfeited or must be repaid under
this Agreement, no interest shall be due on such amounts prior to demand, and
the temporary use of such funds shall be deemed to be adequate consideration for
all of your remaining obligations under this Agreement, including your waivers
and releases.

          If a court finds that any provision of this Agreement is
unenforceable, that provision will be severed and the balance of the Agreement
will be enforceable; except that if paragraphs 3, 4 or 5 are found to be
unenforceable, then this entire Agreement may, at the Company's option, be
declared to be null and void, in which case you shall immediately return the
severance benefits to the Company.

          7.   NON-DISCLOSURE.  You agree not to disclose the existence or 
               --------------
contents of this Agreement, or the benefits provided to you hereunder, unless
required by law. This restriction will not apply to disclosure by you to members
of your immediate family or to your legal, tax, or financial advisors, provided
that you advise them of this provision, and you agree to use your best efforts
to protect against any further disclosure by those persons.

accepting the severance benefits, you are giving up any right that you have or
may have to reapply for or be reinstated to employment with the Company; that
you will not hereafter seek permanent employment by the Company; and that if you
do, the Company's refusal to hire you or its termination of such employment
shall be conclusively presumed to be based solely on this Agreement.

          9.   TIME TO CONSIDER AND RIGHT TO REVOKE.  You may, at your option, 
               ------------------------------------     
before signing this Agreement, consider it for a period of ten (10) days from
the day it is presented to you. During that period you should review and discuss
it with your attorney. After you sign this Agreement you will have a period of
seven (7) days to revoke it by notifying the Company in writing delivered to the
                                                                ---------       
Director of Human Resources, in Omaha, Nebraska.  This Agreement will not become
effective or enforceable until the seven (7) day revocation period expires, and
no payments under paragraph 2 shall be required until such period has expired
without revocation.

          10.  REFERENCES.  The Company agrees to provide neutral reference 
               ---------- 
responses to inquiries about you from prospective employers. The response will
include a verification of past employment, dates of employment and job titles.

          11.  NO ADMISSION.  Neither the payment of any sum of money nor the
               ------------                                                  
execution of this Agreement by the Company shall in any way be construed as an
admission of any wrongful or unlawful act whatsoever, and the Company
specifically disclaims any liability to you, or wrongful or unlawful act against
you.

          12.  GOVERNING LAW.  This Agreement will be interpreted and enforced 
               -------------  
under the laws of the State of Nebraska.

3.   DUTIES OF HADDIX; EXCLUSIVITY

     (A)  Haddix shall provide such consultation, advisory services and
          assistance regarding the technical management, operations and

          generally on Schedule A.

<PAGE>
 
     expenditure to be reimbursed by CSG, and shall not, in performing his

     liability.

6.   OWNERSHIP OF WORK PRODUCT
- --   -------------------------

     All Work Product created or developed by Haddix during the term of this
     Agreement is and shall be the exclusive property of CSG, and all title and
     interest therein shall vest in CSG and shall be deemed to be a work made
     for hire and made in the course of the services rendered hereunder.  To the
     extent that title to any such Work Product may not, by operation of law,
     vest in CSG or such Work Product may not be considered works made for hire,
     all rights, title and interest therein are hereby irrevocably assigned to
     CSG for the purposes of the United States copyright laws and the laws of
     any other country in which the work is to be performed. Additionally, to

     person designated by CSG, such assistance as CSG, in its sole discretion,
     deems necessary to perfect the rights defined in this paragraph.  CSG will
     pay Haddix for such assistance at double the daily rate of compensation
     that is set forth on Exhibit A attached hereto.  "Work Product" includes,
     but is not limited to, all information, reports, studies, object or source
     code, flow charts, diagrams and other tangible or intangible material of
     any nature whatsoever produced as a result of the performance of this
     Agreement, as well as all copies thereof.

     Haddix agrees to sign all papers, take all rightful oaths and perform all
     acts necessary to make this Agreement effective as to any particular ideas
     or applications for letters, patents covering same, domestic or foreign,
     and including any extensions, division or reissues thereof, and Haddix
     agrees to do all lawful acts to protect CSG's rights and interests and
     those of any parent or affiliated companies, including the giving of
     testimony.  Haddix will be compensated for time spent fulfilling these
     obligations at double the rate as for performing his services hereunder.

     Unless otherwise requested by CSG, upon the completion of the services to
     be performed under each Schedule of this Agreement or upon the earlier
     termination of each such Schedule, Haddix shall immediately turn over to
     CSG all materials and deliverables developed pursuant to such Schedule.

     If Haddix becomes a party to or other participant in, or is threatened to
     be made a party to or witness or other participant, in a suit, proceeding
     or alternative dispute resolution mechanism, whether civil, criminal,
     administrative, investigative or other (a "Claim") by reason of Haddix's
     position as an advisor or consultant to CSG or by reason of any action or
     inaction on the part of Haddix at the request of CSG, CSG shall indemnify
     Haddix for any expenses (including attorneys' fees) incurred in defending
     such Claim(s).  This Section shall not apply with respect to acts or
     omissions from which Haddix may not be relieved of liability under
     applicable law, or any Claim(s) initiated or brought voluntarily by Haddix
     and not by way of defense.


8.   CONFIDENTIALITY
- --   ---------------

     Haddix shall not, upon termination of this Agreement, publish or disclose,
     without the prior written consent of CSG, any business record, memorandum,
     paper or document, any correspondence, product specification or code, cost
     data, customer list, estimate, market survey or any other document
     containing any information or trade secret relating to CSG's business, or
     that of its customers, subsidiaries, parents or affiliates.


9.   RELATIONSHIP AND TAXES
- --   ----------------------

     Each party to this Agreement shall be and act as an independent contractor
     and not as an agent or partner of, or joint venturer with, the other party
     for any purpose, and neither party by virtue of this Agreement shall have
     any right, power or authority to act or create any obligation, expressed or
     implied, on behalf of the other party.  Haddix acknowledges and agrees
     that, under no circumstances, shall he be considered an employee of CSG
     within the meaning or application of any national or state unemployment
     insurance law, old age benefit law, workmen's compensation or industrial
     accident law, or other industrial or labor law, any tax law, or any CSG

     Haddix hereby represents, covenants and warrants to CSG that Haddix has
     full power and authority to enter into this Agreement and to render the
     services contemplated hereby.  Haddix represents, covenants and warrants
     that his entering into this Agreement and performance hereunder shall not,
     for any reason whatsoever, constitute a breach by Haddix of any duty owed
     to a third party, including, but not limited to, a former employer.  Haddix
     further represents, covenants and warrants that he shall not, 
<PAGE>
 
     throughout the term of this Agreement, utilize any proprietary information
     not belonging to Haddix which would result in a breach of any such duty.

12.  ENTIRE AGREEMENT
- ---  ----------------

     This Agreement and any schedules or agreements referred to or incorporated
     herein constitutes and expresses the entire agreement and understanding
     between the parties hereto with respect to all matters herein contained and
     supersedes all prior agreements between the parties.  There is no
     statement, promise, agreement or obligation in existence which conflicts
     with the terms of this Agreement or may modify, enlarge or invalidate this
     Agreement or any provisions hereof.


13.  SUCCESSORS AND ASSIGNS
- ---  ----------------------

     All covenants, stipulations and promises in this Agreement shall be binding
     upon and inure to the benefit of the parties hereto and their respective
     heirs, executors, representatives, successors and permitted assigns.
     Neither party shall have the right to assign or otherwise transfer any

     the other party; provided, however, that a successor in interest by merger,
     operation of law, assignment, purchase or otherwise of the entire business
     of CSG shall acquire the entire interest of CSG hereunder without Haddix's
     prior written consent; and further provided that CSG may assign its rights

provided by Haddix under the Agreement shall consist of the following:

Haddix shall be chiefly responsible for advising CSG's CFO, COO, CEO and General
Counsel in the technical management and administration of the Company.  Special
Projects shall be assigned from time to time by any and all of these
individuals.

The parties agree that additional Schedules may be added to this Agreement from
time to time upon the mutual written consent of the parties, which supplement or
amend this initial statement describing the duties of Haddix.

SECTION 4: COMPENSATION.  Haddix shall be paid a consulting fee at a rate of
- ------------------------

expenses and taxes, for the provision of services provided hereunder.  For this
quarterly consulting fee, Haddix will be expected to work three (3) days per
calendar quarter.  CSG may not require Haddix to work additional days, but shall
compensate Haddix at a daily rate of $1,000 for each day worked (based on an 8
hour work day) in excess thereof.  Haddix will be entitled to receive a pro-
rated amount of such daily rate for any partial days worked in excess of one (1)
day per month.  Haddix and CSG agree and understand that the compensation paid
hereunder is significantly less than the market rate Haddix may demand in the
open marketplace.  The parties agree that this reduced rate is in partial
consideration of the benefits granted to Haddix pursuant to the Separation
Agreement, which agreement is hereby incorporated into this Agreement by
reference, and which benefits include, but are not limited to, the vesting of
9,800 Incentive Stock Options on December 30, 1997.  Regardless of the actual
amount of work expected of or performed by Haddix during the term of this
Agreement, the restriction on Haddix providing consulting services to any
competitor of CSG as set forth in Section 3(B) of this Agreement shall remain in
full force and effect throughout the term hereof.

                           INDEMNIFICATION AGREEMENT
                           -------------------------

     This Indemnification Agreement ("Agreement") is made and entered into as of
the 28th day of January, 1997, by and between CSG SYSTEMS INTERNATIONAL, INC., a
Delaware corporation, and its wholly-owned subsidiary, CSG SYSTEMS, INC. (such
two corporations being collectively referred to herein as the "Company") and
ROYCE J. HOLLAND ("Indemnitee").


                                 RECITALS:


     A.   The Company and Indemnitee recognize the continued difficulty in
obtaining liability insurance for its directors, officers, employees, agents,
and fiduciaries, the significant increases in the cost of such insurance and the
general reductions in the coverage of such insurance.

     B.   The Company and Indemnitee further recognize the substantial increase
in corporate litigation in general, subjecting directors, officers, employees,
agents, and fiduciaries to extensive litigation risks at the same time as the
availability and coverage of liability insurance has been severely reduced.

     C.   Indemnitee does not regard the current protection available as
adequate under the present circumstances, and Indemnitee and other directors,
officers, employees, agents, and fiduciaries of the Company may not be willing
to continue to serve in such capacities without additional protection.

     D.   The Company desires to attract and retain the services of highly
qualified individuals, such as Indemnitee, to serve the Company and, in part, in
order to induce Indemnitee to continue to provide services to the Company,
wishes to provide for the indemnification and advancing of expenses to
Indemnitee to the maximum extent permitted by law.

     E.   In view of the considerations set forth above, the Company desires
that Indemnitee be indemnified by the Company as set forth herein.

     NOW, THEREFORE, the Company and Indemnitee hereby agree as follows:

     1.   Indemnification.
          --------------- 

          (a)  Indemnification of Expenses.  The Company shall indemnify
               ---------------------------                              
Indemnitee to the fullest extent permitted by law if Indemnitee was or is or
becomes a party to or witness or other participant in, or is threatened to be
made a party to or witness or other participant in, any threatened, pending, or
completed action, suit, proceeding, or alternative dispute resolution mechanism,
or any hearing, inquiry, or investigation that Indemnitee in good faith believes
might lead to the institution of any such action, suit, proceeding, or
alternative dispute resolution mechanism, whether civil, criminal,
administrative, investigative, or other (hereinafter a "Claim") by reason of (or
arising in part out of) any event or occurrence related to the fact that
Indemnitee is 
<PAGE>
 
or was a director, officer, employee, agent, or fiduciary of the Company, or any
subsidiary of the Company, or is or was serving at the request of the Company as
a director, officer, employee, agent, or fiduciary of another corporation,
partnership, joint venture, trust, or other enterprise, or by reason of any
action or inaction on the part of Indemnitee while serving in such capacity
(hereinafter as "Indemnifiable Event") against any and all expenses (including
attorneys' fees and all other costs, expenses, and obligations incurred in
connection with investigating, defending, being a witness in or participating in
(including on appeal), or preparing to defend, be a witness in, or participate
in, any such action, suit, proceeding, alternative dispute resolution mechanism,
hearing, inquiry, or investigation), judgments, fines, penalties and amounts
paid in settlement (if such settlement is approved in advance by the Company,
which approval shall not be unreasonably withheld) of such Claim and any
federal, state, local, or foreign taxes imposed on Indemnitee as a result of the
actual or deemed receipt of any payments under this Agreement (collectively,
hereinafter "Expenses"), including all interest, assessments, and other charges
paid or payable in connection with or in respect of such Expenses. Such payment
of Expenses shall be made by the Company as soon as practicable but in any event
no later than five days after written demand by Indemnitee therefor is presented
to the Company.

          (b)  Reviewing Party.  Notwithstanding the foregoing, (i) the
               ---------------                                         
obligations of the Company under Section 1(a) shall be subject to the condition
that the Reviewing Party (as described in Section 10(e) hereof) shall not have
determined (in a written opinion, in any case in which the Independent Legal
Counsel referred to in Section 1(c) hereof is involved) that Indemnitee would
not be permitted to be indemnified under applicable law, and (ii) the obligation
of the Company to make an advance payment of Expenses to Indemnitee pursuant to
Section 2(a) (an "Expense Advance") shall be subject to the condition that, if,
when, and to the extent that the Reviewing Party determines that Indemnitee
would not be permitted to be so indemnified under applicable law, the Company
shall be entitled to be reimbursed by Indemnitee (who hereby agrees to reimburse
the Company) for all such amounts theretofore paid; provided, however, that if
Indemnitee has commenced or thereafter commences legal proceedings in a court of
competent jurisdiction to secure a determination that Indemnitee should be
indemnified under applicable law, any determination made by the Reviewing Party
that Indemnitee would not be permitted to be indemnified under applicable law
shall not be binding and Indemnitee shall not be required to reimburse the
Company for any Expense Advance until a final judicial determination is made
with respect thereto (as to which all rights of appeal therefrom have been
exhausted or lapsed).  Indemnitee's obligation to reimburse the Company for any
Expense Advance shall be unsecured, and no interest shall be charged thereon.
If there has not been a Change in Control (as defined in Section 10(c) hereof),
then the Reviewing Party shall be selected by the Board of Directors; and if
there has been such a Change in Control (other than a Change in Control which
has been approved by a majority of the Company's Board of Directors who were
directors immediately prior to such Change in Control), then the Reviewing Party
shall be the Independent Legal Counsel referred to in Section 1(c) hereof.  If
there has been no determination by the Reviewing Party or if the Reviewing Party
determines that Indemnitee substantively would not be permitted to be
indemnified in whole or in part under applicable law, then Indemnitee shall have
the right to commence litigation seeking an initial determination by the court
or challenging any such determination by the Reviewing Party or any aspect
thereof, including the legal or factual bases therefor, and the Company hereby
consents to service of process and to appear in any such proceeding.  Any
determination by the 
<PAGE>
 
Reviewing Party otherwise shall be conclusive and binding on the Company and
Indemnitee.

          (c)  Change in Control.  The Company agrees that if there is a Change
               -----------------                                               
in Control of the Company (other than a Change in Control which has been
approved by a majority of the Company's Board of Directors who were directors
immediately prior to such Change in Control) then, with respect to all matters
thereafter arising concerning the rights of Indemnitee to payments of Expenses
and Expense Advances under this Agreement or any other agreement under the
Company's Certificate of Incorporation or Bylaws as now or hereafter in effect,
Independent Legal Counsel (as defined in Section 10(d) hereof) shall be selected
by Indemnitee and approved by the Company (which approval shall not be
unreasonably withheld).  Such counsel, among other things, shall render its
written opinion to the Company and Indemnitee as to whether and to what extent
Indemnitee would be permitted to be indemnified under applicable law, and the
Company agrees to abide by such opinion.  The Company agrees to pay the
reasonable fees of the Independent Legal Counsel referred to above and to fully
indemnify such counsel against any and all expenses (including attorneys' fees),
claims, liabilities, and damages arising out of or relating to this Agreement or
its engagement pursuant hereto.

          (d)  Mandatory Payment of Expenses.  Notwithstanding any other
               -----------------------------                            
provision of this Agreement other than Section 9 hereof, to the extent that
Indemnitee has been successful on the merits or otherwise, including, without
limitation, the dismissal of an action without prejudice, in defense of any
action, suit, proceeding, inquiry, or investigation referred to in Section 1(a)
hereof or in the defense of any claim, issue, or matter therein, Indemnitee
shall be indemnified against all Expenses incurred by Indemnitee in connection
therewith.

     2.   Expenses; Indemnification Procedure.
          ----------------------------------- 

          (a)  Advancement of Expenses.  The Company shall advance all Expenses
               -----------------------                                         
incurred by Indemnitee.  The advances to be made hereunder shall be paid by the
Company to Indemnitee as soon as practicable but in any event no later than five
days after written demand by Indemnitee therefor to the Company.

          (b)  Notice/Cooperation by Indemnitee.  Indemnitee shall, as a
               --------------------------------                         
condition precedent to Indemnitee's right to be indemnified under this
Agreement, give the Company notice in writing as soon as practicable of any
Claim made against Indemnitee for which Indemnification will or could be sought
under this Agreement.  Notice to the Company shall be directed to the Chief
Executive Officer of the Company at the address shown on the signature page of
this Agreement (or such other address as the Company shall designate in writing
to Indemnitee).  In addition, Indemnitee shall give the Company such information
and cooperation as it may reasonably require and as shall be within Indemnitee's
power.

          (c)  No Presumptions; Burden of Proof.  For purposes of this
               --------------------------------                       
Agreement, the termination of any Claim by judgment, order, settlement (whether
with or without court approval), or conviction, or upon a plea of nolo
                                                                  ----
contendere, or its equivalent, shall not create a presumption that Indemnitee
- ----------                                                                   
did not meet any particular standard of conduct or have any particular belief or
that a court has determined that indemnification is not permitted by applicable
law.  In addition, neither 
<PAGE>
 
the failure of the Reviewing Party to have made a determination as to whether
Indemnitee has met any particular standard of conduct or had any particular
belief, nor an actual determination by the Reviewing Party that Indemnitee has
not met such standard of conduct or did not have such belief, prior to the
commencement of legal proceedings by Indemnitee to secure a judicial
determination that Indemnitee should be indemnified under applicable law, shall
be a defense to Indemnitee's claim or create a presumption that Indemnitee has
not met any particular standard of conduct or did not have any particular
belief. In connection with any determination by the Reviewing Party or otherwise
as to whether Indemnitee is entitled to be indemnified hereunder, the burden of
proof shall be on the Company to establish that Indemnitee is not so entitled.

          (d)  Notice to Insurers.  If, at the time of the receipt by the
               ------------------                                        
Company of a notice of a Claim pursuant to Section 2(b) hereof, the Company has
liability insurance in effect which may cover such Claim, the Company shall give
prompt notice of the commencement of such Claim to the insurers in accordance
with the procedures set forth in the respective policies.  The Company shall
thereafter take all necessary or desirable action to cause such insurers to pay,
on behalf of Indemnitee, all amounts payable as a result of such action, suit,
proceeding, inquiry, or investigation in accordance with the terms of such
policies.

          (e)  Selection of Counsel.  In the event the Company shall be
               --------------------                                    
obligated hereunder to pay the Expenses of any Claim, the Company, if
appropriate, shall be entitled to assume the defense of such Claim with counsel
approved by Indemnitee, upon the delivery to Indemnitee of written notice of its
election so to do.  After delivery of such notice, approval of such counsel by
Indemnitee and the retention of such counsel by the Company, the Company will
not be liable to Indemnitee under this Agreement for any fees of counsel
subsequently incurred by Indemnitee with respect to the same Claim; provided
that, (i) Indemnitee shall have the right to employ Indemnitee's counsel in any
such Claim at Indemnitee's expense and (ii) if (A) the employment of counsel by
Indemnitee has been previously authorized by the Company, (B) Indemnitee shall
have reasonably concluded that there may be a conflict of interest between the
Company and Indemnitee in the conduct of any such defense, or (C) the Company
shall not continue to retain such counsel to defend such Claim, then the fees
and expenses of Indemnitee's counsel shall be at the expense of the Company.
<PAGE>
 
     3.   Additional Indemnification Rights; Nonexclusivity.
          ------------------------------------------------- 

          (a)  Scope.  The Company hereby agrees to indemnify Indemnitee to the
               -----                                                           
fullest extent permitted by law, notwithstanding that such indemnification is
not specifically authorized by the other provisions of this Agreement, the
Company's Certificate of Incorporation, the Company's Bylaws, or by statute.  In
the event of any change after the date of this Agreement in any applicable law,
statute, or rule which expands the right of a Delaware corporation to indemnify
a member of its Board of Directors or an officer, employee, agent, or fiduciary,
it is the intent of the parties hereto that Indemnitee shall enjoy by this
Agreement the greater benefits afforded by such change.  In the event of any
change in any applicable law, statute, or rule which narrows the right of a
Delaware corporation to indemnify a member of its Board of Directors or an
officer, employee, agent, or fiduciary, such change, to the extent not otherwise
required by such law, statute, or rule to be applied to this Agreement, shall
have no effect on this Agreement or the parties' rights and obligations
hereunder except as set forth in Section 8(a) hereof.


          (b)  Nonexclusivity.  The indemnification provided by this Agreement
               --------------                                                 
shall be in addition to any rights to which Indemnitee may be entitled under the
Company's Certificate of Incorporation, its Bylaws, any agreement, any vote of
stockholders or disinterested directors, the General Corporation Law of the
State of Delaware, or otherwise.  The indemnification provided under this
Agreement shall continue as to Indemnitee for any action taken or not taken by
Indemnitee while serving in an indemnified capacity even though Indemnitee may
have ceased to serve in such capacity.

     4.   No Duplication of Payments.  The Company shall not be liable under
          --------------------------                                        
this Agreement to make any payment in connection with any Claim made against
Indemnitee to the extent Indemnitee has otherwise actually received payment
(under any insurance policy, Certificate of Incorporation, Bylaw, or otherwise)
of the amounts otherwise indemnifiable hereunder.

     5.   Partial Indemnification.  If Indemnitee is entitled under any
          -----------------------                                      
provision of this Agreement to indemnification by the Company for some or a
portion of Expenses incurred in connection with any Claim, but not, however, for
all of the total amount thereof, then the Company nevertheless shall indemnify
Indemnitee for the portion of such Expenses to which Indemnitee is entitled.

     6.   Mutual Acknowledgment.  Both the Company and Indemnitee acknowledge
          ---------------------                                              
that in certain instances Federal law or applicable public policy may prohibit
the Company from indemnifying its directors, officers, employees, agents, or
fiduciaries under this Agreement or otherwise.  Indemnitee understands and
acknowledges that the Company has undertaken or may be required in the future to
undertake with the Securities and Exchange Commission to submit the question of
indemnification to a court in certain circumstances for a determination of the
Company's right under public policy to indemnify Indemnitee.

     7.   Liability Insurance.  To the extent the Company maintains liability
          -------------------                                                
insurance applicable to directors, officers, employees, agents, or fiduciaries,
Indemnitee shall be covered by such policies in such a manner as to provide
Indemnitee the same rights and benefits as are 
<PAGE>
 
accorded to the most favorably insured of the Company's directors, if Indemnitee
is a director; or of the Company's officers, if Indemnitee is not a director of
the Company but is an officer; or of the Company's key employees, agents, or
fiduciaries, if Indemnitee is not an officer or director but is a key employee,
agent, or fiduciary.


     8.   Exceptions.  Any other provision herein to the contrary
          ----------                                             
notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement:

          (a)  Excluded Action or Omissions.  To indemnify Indemnitee for acts,
               ----------------------------                                    
omissions, or transactions from which Indemnitee may not be relieved of
liability under applicable law;


          (b)  Claims Initiated by Indemnitee.  To indemnify or advance expenses
               ------------------------------                                   
to Indemnitee with respect to Claims initiated or brought voluntarily by
Indemnitee and not by way of defense, except (i) with respect to actions or
proceedings brought to establish or enforce a right to indemnification under
this Agreement or any other agreement or insurance policy or under the Company's
Certificate of Incorporation or Bylaws now or hereafter in effect relating to
Claims for Indemnifiable Events, (ii) in specific cases if the Board of
Directors has approved the initiation or bringing of such Claim, or (iii) as
otherwise required under Section 145 of the Delaware General Corporation Law,
regardless of whether Indemnitee ultimately is determined to be entitled to such
indemnification, advance expense payment, or insurance recovery, as the case may
be;

          (c)  Lack of Good Faith.  To indemnify Indemnitee for any expenses
               ------------------                                           
incurred by Indemnitee with respect to any proceeding instituted by Indemnitee
to enforce or interpret this Agreement, if a court of competent jurisdiction
determines that each of the material assertions made by Indemnitee in such
proceeding was not made in good faith or was frivolous; or

          (d)  Claims Under Section 16(b).  To indemnify Indemnitee for expenses
               --------------------------                                       
and the payment of profits arising from the purchase and sale by Indemnitee of
securities in violation of Section 16(b) of the Securities Exchange Act of 1934,
as amended, or any similar successor statute.

     9.   Period of Limitations.  No legal action shall be brought and no cause
          ---------------------                                                
of action shall be asserted by or in the right of the Company against
Indemnitee, Indemnitee's estate, spouse, heirs, executors, or personal or legal
representatives after the expiration of two years from the date of accrual of
such cause of action, and any claim or cause of action of the Company shall be
extinguished and deemed released unless asserted by the timely filing of a legal
action within such two-year period; provided, however, that if any shorter
                                    --------  -------                     
period of limitations is otherwise applicable to any such cause of action, such
shorter period shall govern.

     10.  Construction of Certain Phrases.
          ------------------------------- 

          (a)  For purposes of this Agreement, references to the "Company" shall
include, in addition to the resulting corporation, any constituent corporation
(including any constituent of a constituent) absorbed in a consolidation or
merger which, if its separate existence had continued, would have had power and
authority to indemnify its directors, officers, employees, agents, or
<PAGE>
 
fiduciaries, so that if Indemnitee is or was a director, officer, employee,
agent, or fiduciary of such constituent corporation, or is or was serving at the
request of such constituent corporation as a director, officer, employee, agent,
or fiduciary of another corporation, partnership, joint venture, employee
benefit plan, trust, or other enterprise, Indemnitee shall stand in the same
position under the provisions of this Agreement with respect to the resulting or
surviving corporation as Indemnitee would have stood with respect to such
constituent corporation if its separate existence had continued.

          (b)  For purposes of this Agreement, references to "other enterprises"
shall include employee benefit plans; references to "fines" shall include any
excise taxes assessed on Indemnitee with respect to an employee benefit plan;
and references to "serving at the request of the Company" shall include any
service as a director, officer, employee, agent, or fiduciary of the Company
which imposes duties on, or involves services by, such director, officer,
employee, agent, or fiduciary with respect to an employee benefit plan, its
participants or its beneficiaries; and if Indemnitee acted in good faith and in
a manner Indemnitee reasonably believed to be in the interests of the
participants and beneficiaries of an employee benefit plan, then Indemnitee
shall be deemed to have acted in a manner "not opposed to the best interests of
the Company" as referred to in this Agreement.

          (c)  For purposes of this Agreement a "Change in Control" shall be
deemed to have occurred if (i) any "person" (as such term is used in Sections
13(d) and 14(d) of the Securities Exchange Act of 1934, as amended), other than
a trustee or other fiduciary holding securities under an employee benefit plan
of the Company or a corporation owned directly or indirectly by the stockholders
of the Company in substantially the same proportions as their ownership of stock
of the Company, (A) who is or becomes the beneficial owner, directly or
indirectly, of securities of the Company representing 10% or more of the
combined voting power of the Company's then outstanding Voting Securities
increases his beneficial ownership of such securities by 5% or more over the
percentage so owned by such person, or (B) becomes the "beneficial owner" (as
defined in Rule 13d-3 under said Act), directly or indirectly, of securities of
the Company representing more than 20% of the total voting power represented by
the Company's then outstanding Voting Securities, (ii) during any period of two
consecutive years, individuals who at the beginning of such period constitute
the Board of Directors of the Company and any new director whose election by the
Board of Directors or nomination for election by the Company's stockholders was
approved by a vote of at least two-thirds of the directors then still in office
who either were directors at the beginning of the period or whose election or
nomination for election was previously so approved cease for any reason to
constitute a majority thereof, or (iii) the stockholders of the Company approve
a merger or consolidation of the Company with any other corporation other than a
merger or consolidation which would result in the Voting Securities of the
Company outstanding immediately prior thereto continuing to represent (either by
remaining outstanding or by being converted into Voting Securities of the
surviving entity) at least 80% of the total voting power represented by the
Voting Securities of the Company or such surviving entity outstanding
immediately after such merger or consolidation, or the stockholders of the
Company approve a plan of complete liquidation of the Company or an agreement
for the sale or disposition by the Company (in one transaction or a series of
transactions) of all or substantially all of the Company's assets.

          (d)  For purposes of this Agreement, "Independent Legal Counsel" shall
mean an attorney or firm of attorneys, selected in accordance with the
provisions of Section 1 (c) hereof, who 
<PAGE>
 
shall not have otherwise performed services for the Company or Indemnitee within
the last three years (other than with respect to matters concerning the rights
of Indemnitee under this Agreement, or of other indemnitees under similar
indemnity agreements).

          (e)  For purposes of this Agreement, a "Reviewing Party" shall mean
any appropriate person or body consisting of a member or members of the
Company's Board of Directors or any other person or body appointed by the Board
of Directors who is not a party to the particular Claim for which Indemnitee is
seeking indemnification, or Independent Legal Counsel.

          (f)  For purposes of this Agreement, "Voting Securities" shall mean
any securities of the Company that vote generally in the election of directors.

     11.  Counterparts.  This Agreement may be executed in one or more
          ------------                                                
counterparts, each of which shall constitute an original.

     12.  Binding Effect; Successors and Assigns.  This Agreement shall be
          --------------------------------------                          
binding upon and inure to the benefit of and be enforceable by the parties
hereto and their respective successors (including any direct or indirect
successor by purchase, merger, consolidation, or otherwise to all or
substantially all of the business and/or assets of the Company), assigns,
spouses, heirs, and personal and legal representatives.  The Company shall
require and cause any successor (whether direct or indirect by purchase, merger,
consolidation, or otherwise) to all, substantially all, or a substantial part of
the business and/or assets of the Company, by written agreement in form and
substance satisfactory to Indemnitee, expressly to assume and agree to perform
this Agreement in the same manner and to the same extent that the Company would
be required to perform if no such succession had taken place.  This Agreement
shall continue in effect regardless of whether Indemnitee continues to serve as
a director, officer, employee, agent, or fiduciary of the Company or of any
other enterprise at the Company's request.
<PAGE>
 
     13.  Attorney's Fees.  In the event that any action is instituted by
          ---------------                                                
Indemnitee under this Agreement or under any liability insurance policies
maintained by the Company to enforce or interpret any of the terms hereof or
thereof, Indemnitee shall be entitled to be paid all Expenses incurred by
Indemnitee with respect to such action, regardless of whether Indemnitee is
ultimately successful in such action, and shall be entitled to the advancement
of Expenses with respect to such action, unless, as a part of such action, a
court of competent jurisdiction over such action determines that each of the
material assertions made by Indemnitee as a basis for such action was not made
in good faith or was frivolous.  In the event of an action instituted by or in
the name of the Company under this Agreement to enforce or interpret any of the
terms of this Agreement, Indemnitee shall be entitled to be paid all Expenses
incurred by Indemnitee in defense of such action (including costs and expenses
incurred with respect to Indemnitee's counterclaims and cross-claims made in
such action) and shall be entitled to the advancement of Expenses with respect
to such action, unless, as a part of such action, a court having jurisdiction
over such action determines that each of Indemnitee's material defenses to such
action was made in bad faith or was frivolous.

     14.  Notice.  All notices and other communications required or permitted
          ------                                                             
hereunder shall be in writing, shall be effective when given, and shall in any
event be deemed to be given (a) five days after deposit with the U.S. Postal
Service or other applicable postal service, if delivered by first class mail
postage prepaid, (b) upon delivery, if delivered by hand, (c) one business day
after the business day of deposit with Federal Express or similar overnight
courier, freight prepaid, or (d) one day after the business day of delivery by
facsimile transmission, if delivered by facsimile transmission, with a copy by

the Indemnitee's address as set forth beneath his signature to this Agreement
and if to the Company at the address of its principal corporate offices
(attention: Secretary) or at such other address as such party may designate by
ten days' advance written notice to the other party hereto.

     15.  Consent to Jurisdiction.  The Company and Indemnitee each hereby
          -----------------------                                         
irrevocably consent to the jurisdiction of the courts of the State of Delaware
for all purposes in connection with any action or proceeding which arises out of
or relates to this Agreement and agree that any action instituted under this
Agreement shall be commenced, prosecuted, and continued only in the Court of
Chancery of the State of Delaware in and for New Castle County, which shall be
the exclusive and only proper forum adjudicating such a claim.

     16.  Severability.  The provisions of this Agreement shall be severable in
          ------------                                                         
the event that any of the provisions hereof (including any provision within a
single section, paragraph, or sentence) are held by a court of competent
jurisdiction to be invalid, void, or otherwise unenforceable, and the remaining
provisions shall remain enforceable to the fullest extent permitted by law.
Furthermore, to the fullest extent possible, the provisions of this Agreement
(including, without limitations, each portion of this Agreement containing any
provision held to be invalid, void, or otherwise unenforceable that is not
itself invalid, void, or unenforceable) shall be construed so as to give effect
to the intent manifested by the provision held invalid, illegal, or
unenforceable.

     17.  Choice of Law.  This Agreement shall be governed by and its provisions
          -------------                                                         
construed and enforced in accordance with the laws of the State of Delaware, as
applied to contracts between Delaware residents, entered into and to be
performed entirely within the State of Delaware, without regard to the conflict
of laws principles thereof.
<PAGE>
 
     18.  Subrogation.  In the event of payment under this Agreement, the
          -----------                                                    
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of Indemnitee, who shall execute all documents required and shall do
all acts that may be necessary to secure such rights and to enable the Company
effectively to bring suit to enforce such rights.

     19.  Amendment and Termination.  No amendment, modification, termination,
          -------------------------                                           
or cancellation of this Agreement shall be effective unless it is in writing
signed by both the parties hereto.  No waiver of any of the provisions of this
Agreement shall be deemed or shall constitute a waiver of any other provisions
hereof (whether or not similar) nor shall such waiver constitute a continuing
waiver.

     20.  Integration and Entire Agreement.  This Agreement sets forth the
          --------------------------------                                
entire understanding between the parties hereto and supersedes and merges all
previous written and oral negotiations, commitments, understandings, and
agreements relating to the subject matter hereof between the parties hereto.

     21.  No Construction as Employment Agreement.  Nothing contained in this
          ---------------------------------------                            
Agreement shall be construed as giving Indemnitee any right to be retained in
the employ of the Company or any of its subsidiaries or to serve on the Board of
Directors of the Company or any of its subsidiaries or to hold any other
position as a representative or designee of the Company or any of its
subsidiaries.

                           INDEMNIFICATION AGREEMENT
                           -------------------------

     This Indemnification Agreement ("Agreement") is made and entered into as of
the 28th day of January, 1997, by and between CSG SYSTEMS INTERNATIONAL, INC., a
Delaware corporation, and its wholly-owned subsidiary, CSG SYSTEMS, INC. (such
two corporations being collectively referred to herein as the "Company") and
BERNARD W. REZNICEK ("Indemnitee").


                                   RECITALS:


     A.   The Company and Indemnitee recognize the continued difficulty in
obtaining liability insurance for its directors, officers, employees, agents,
and fiduciaries, the significant increases in the cost of such insurance and the
general reductions in the coverage of such insurance.

     B.   The Company and Indemnitee further recognize the substantial increase
in corporate litigation in general, subjecting directors, officers, employees,
agents, and fiduciaries to extensive litigation risks at the same time as the
availability and coverage of liability insurance has been severely reduced.

     C.   Indemnitee does not regard the current protection available as
adequate under the present circumstances, and Indemnitee and other directors,
officers, employees, agents, and fiduciaries of the Company may not be willing
to continue to serve in such capacities without additional protection.

     D.   The Company desires to attract and retain the services of highly
qualified individuals, such as Indemnitee, to serve the Company and, in part, in
order to induce Indemnitee to continue to provide services to the Company,
wishes to provide for the indemnification and advancing of expenses to
Indemnitee to the maximum extent permitted by law.

     E.   In view of the considerations set forth above, the Company desires
that Indemnitee be indemnified by the Company as set forth herein.

     NOW, THEREFORE, the Company and Indemnitee hereby agree as follows:

     1.   Indemnification.
          --------------- 

          (a)  Indemnification of Expenses.  The Company shall indemnify
               ---------------------------                              
Indemnitee to the fullest extent permitted by law if Indemnitee was or is or
becomes a party to or witness or other participant in, or is threatened to be
made a party to or witness or other participant in, any threatened, pending, or
completed action, suit, proceeding, or alternative dispute resolution mechanism,
or any hearing, inquiry, or investigation that Indemnitee in good faith believes
might 
<PAGE>
 
lead to the institution of any such action, suit, proceeding, or alternative
dispute resolution mechanism, whether civil, criminal, administrative,
investigative, or other (hereinafter a "Claim") by reason of (or arising in part
out of) any event or occurrence related to the fact that Indemnitee is or was a
director, officer, employee, agent, or fiduciary of the Company, or any
subsidiary of the Company, or is or was serving at the request of the Company as
a director, officer, employee, agent, or fiduciary of another corporation,
partnership, joint venture, trust, or other enterprise, or by reason of any
action or inaction on the part of Indemnitee while serving in such capacity
(hereinafter as "Indemnifiable Event") against any and all expenses (including
attorneys' fees and all other costs, expenses, and obligations incurred in
connection with investigating, defending, being a witness in or participating in
(including on appeal), or preparing to defend, be a witness in, or participate
in, any such action, suit, proceeding, alternative dispute resolution mechanism,
hearing, inquiry, or investigation), judgments, fines, penalties and amounts
paid in settlement (if such settlement is approved in advance by the Company,
which approval shall not be unreasonably withheld) of such Claim and any
federal, state, local, or foreign taxes imposed on Indemnitee as a result of the
actual or deemed receipt of any payments under this Agreement (collectively,
hereinafter "Expenses"), including all interest, assessments, and other charges
paid or payable in connection with or in respect of such Expenses. Such payment
of Expenses shall be made by the Company as soon as practicable but in any event
no later than five days after written demand by Indemnitee therefor is presented
to the Company.

          (b)  Reviewing Party.  Notwithstanding the foregoing, (i) the
               ---------------                                         
obligations of the Company under Section 1(a) shall be subject to the condition
that the Reviewing Party (as described in Section 10(e) hereof) shall not have
determined (in a written opinion, in any case in which the Independent Legal
Counsel referred to in Section 1(c) hereof is involved) that Indemnitee would
not be permitted to be indemnified under applicable law, and (ii) the obligation
of the Company to make an advance payment of Expenses to Indemnitee pursuant to
Section 2(a) (an "Expense Advance") shall be subject to the condition that, if,
when, and to the extent that the Reviewing Party determines that Indemnitee
would not be permitted to be so indemnified under applicable law, the Company
shall be entitled to be reimbursed by Indemnitee (who hereby agrees to reimburse
the Company) for all such amounts theretofore paid; provided, however, that if
Indemnitee has commenced or thereafter commences legal proceedings in a court of
competent jurisdiction to secure a determination that Indemnitee should be
indemnified under applicable law, any determination made by the Reviewing Party
that Indemnitee would not be permitted to be indemnified under applicable law
shall not be binding and Indemnitee shall not be required to reimburse the
Company for any Expense Advance until a final judicial determination is made
with respect thereto (as to which all rights of appeal therefrom have been
exhausted or lapsed).  Indemnitee's obligation to reimburse the Company for any
Expense Advance shall be unsecured, and no interest shall be charged thereon.
If there has not been a Change in Control (as defined in Section 10(c) hereof),
then the Reviewing Party shall be selected by the Board of Directors; and if
there has been such a Change in Control (other than a Change in Control which
has been approved by a majority of the Company's Board of Directors who were
directors immediately prior to such Change in Control), then the Reviewing Party
shall be the Independent Legal Counsel referred to in Section 1(c) hereof.  If
there has been no determination by the Reviewing Party or if the Reviewing Party
determines that Indemnitee 
<PAGE>
 
substantively would not be permitted to be indemnified in whole or in part under
applicable law, then Indemnitee shall have the right to commence litigation
seeking an initial determination by the court or challenging any such
determination by the Reviewing Party or any aspect thereof, including the legal
or factual bases therefor, and the Company hereby consents to service of process
and to appear in any such proceeding. Any determination by the Reviewing Party
otherwise shall be conclusive and binding on the Company and Indemnitee.

          (c)  Change in Control.  The Company agrees that if there is a Change
               -----------------                                               
in Control of the Company (other than a Change in Control which has been
approved by a majority of the Company's Board of Directors who were directors
immediately prior to such Change in Control) then, with respect to all matters
thereafter arising concerning the rights of Indemnitee to payments of Expenses
and Expense Advances under this Agreement or any other agreement under the
Company's Certificate of Incorporation or Bylaws as now or hereafter in effect,
Independent Legal Counsel (as defined in Section 10(d) hereof) shall be selected
by Indemnitee and approved by the Company (which approval shall not be
unreasonably withheld).  Such counsel, among other things, shall render its
written opinion to the Company and Indemnitee as to whether and to what extent
Indemnitee would be permitted to be indemnified under applicable law, and the
Company agrees to abide by such opinion.  The Company agrees to pay the
reasonable fees of the Independent Legal Counsel referred to above and to fully
indemnify such counsel against any and all expenses (including attorneys' fees),
claims, liabilities, and damages arising out of or relating to this Agreement or
its engagement pursuant hereto.

          (d)  Mandatory Payment of Expenses.  Notwithstanding any other
               -----------------------------                            
provision of this Agreement other than Section 9 hereof, to the extent that
Indemnitee has been successful on the merits or otherwise, including, without
limitation, the dismissal of an action without prejudice, in defense of any
action, suit, proceeding, inquiry, or investigation referred to in Section 1(a)
hereof or in the defense of any claim, issue, or matter therein, Indemnitee
shall be indemnified against all Expenses incurred by Indemnitee in connection
therewith.

     2.   Expenses; Indemnification Procedure.
          ----------------------------------- 

          (a) Advancement of Expenses.  The Company shall advance all Expenses
              -----------------------                                         
incurred by Indemnitee.  The advances to be made hereunder shall be paid by the
Company to Indemnitee as soon as practicable but in any event no later than five
days after written demand by Indemnitee therefor to the Company.

          (b)  Notice/Cooperation by Indemnitee.  Indemnitee shall, as a
               --------------------------------                         
condition precedent to Indemnitee's right to be indemnified under this
Agreement, give the Company notice in writing as soon as practicable of any
Claim made against Indemnitee for which Indemnification will or could be sought
under this Agreement.  Notice to the Company shall be directed to the Chief
Executive Officer of the Company at the address shown on the signature page of
this Agreement (or such other address as the Company shall designate in writing
to Indemnitee).  In addition, Indemnitee shall give the Company such information
and cooperation as it may reasonably require and as shall be within Indemnitee's
power.
<PAGE>
 
          (c)  No Presumptions; Burden of Proof.  For purposes of this
               --------------------------------                       
Agreement, the termination of any Claim by judgment, order, settlement (whether
with or without court approval), or conviction, or upon a plea of nolo
                                                                  ----
contendere, or its equivalent, shall not create a presumption that Indemnitee
- ----------                                                                   
did not meet any particular standard of conduct or have any particular belief or
that a court has determined that indemnification is not permitted by applicable
law.  In addition, neither the failure of the Reviewing Party to have made a
determination as to whether Indemnitee has met any particular standard of
conduct or had any particular belief, nor an actual determination by the
Reviewing Party that Indemnitee has not met such standard of conduct or did not
have such belief, prior to the commencement of legal proceedings by Indemnitee
to secure a judicial determination that Indemnitee should be indemnified under
applicable law, shall be a defense to Indemnitee's claim or create a presumption
that Indemnitee has not met any particular standard of conduct or did not have
any particular belief.  In connection with any determination by the Reviewing
Party or otherwise as to whether Indemnitee is entitled to be indemnified
hereunder, the burden of proof shall be on the Company to establish that
Indemnitee is not so entitled.

          (d)  Notice to Insurers.  If, at the time of the receipt by the
               ------------------                                        
Company of a notice of a Claim pursuant to Section 2(b) hereof, the Company has
liability insurance in effect which may cover such Claim, the Company shall give
prompt notice of the commencement of such Claim to the insurers in accordance
with the procedures set forth in the respective policies.  The Company shall
thereafter take all necessary or desirable action to cause such insurers to pay,
on behalf of Indemnitee, all amounts payable as a result of such action, suit,
proceeding, inquiry, or investigation in accordance with the terms of such
policies.

          (e)  Selection of Counsel.  In the event the Company shall be
               --------------------                                    
obligated hereunder to pay the Expenses of any Claim, the Company, if
appropriate, shall be entitled to assume the defense of such Claim with counsel
approved by Indemnitee, upon the delivery to Indemnitee of written notice of its
election so to do.  After delivery of such notice, approval of such counsel by
Indemnitee and the retention of such counsel by the Company, the Company will
not be liable to Indemnitee under this Agreement for any fees of counsel
subsequently incurred by Indemnitee with respect to the same Claim; provided
that, (i) Indemnitee shall have the right to employ Indemnitee's counsel in any
such Claim at Indemnitee's expense and (ii) if (A) the employment of counsel by
Indemnitee has been previously authorized by the Company, (B) Indemnitee shall
have reasonably concluded that there may be a conflict of interest between the
Company and Indemnitee in the conduct of any such defense, or (C) the Company
shall not continue to retain such counsel to defend such Claim, then the fees
and expenses of Indemnitee's counsel shall be at the expense of the Company.

     3.   Additional Indemnification Rights; Nonexclusivity.
          ------------------------------------------------- 

          (a)  Scope.  The Company hereby agrees to indemnify Indemnitee to the
               -----                                                           
fullest extent permitted by law, notwithstanding that such indemnification is
not specifically authorized by the other provisions of this Agreement, the
Company's Certificate of Incorporation, the 
<PAGE>
 
Company's Bylaws, or by statute. In the event of any change after the date of
this Agreement in any applicable law, statute, or rule which expands the right
of a Delaware corporation to indemnify a member of its Board of Directors or an
officer, employee, agent, or fiduciary, it is the intent of the parties hereto
that Indemnitee shall enjoy by this Agreement the greater benefits afforded by
such change. In the event of any change in any applicable law, statute, or rule
which narrows the right of a Delaware corporation to indemnify a member of its
Board of Directors or an officer, employee, agent, or fiduciary, such change, to
the extent not otherwise required by such law, statute, or rule to be applied to
this Agreement, shall have no effect on this Agreement or the parties' rights
and obligations hereunder except as set forth in Section 8(a) hereof.

          (b)  Nonexclusivity.  The indemnification provided by this Agreement
               --------------                                                 
shall be in addition to any rights to which Indemnitee may be entitled under the
Company's Certificate of Incorporation, its Bylaws, any agreement, any vote of
stockholders or disinterested directors, the General Corporation Law of the
State of Delaware, or otherwise.  The indemnification provided under this
Agreement shall continue as to Indemnitee for any action taken or not taken by
Indemnitee while serving in an indemnified capacity even though Indemnitee may
have ceased to serve in such capacity.

     4.   No Duplication of Payments.  The Company shall not be liable under
          --------------------------                                        
this Agreement to make any payment in connection with any Claim made against
Indemnitee to the extent Indemnitee has otherwise actually received payment
(under any insurance policy, Certificate of Incorporation, Bylaw, or otherwise)
of the amounts otherwise indemnifiable hereunder.

     5.   Partial Indemnification.  If Indemnitee is entitled under any
          -----------------------                                      
provision of this Agreement to indemnification by the Company for some or a
portion of Expenses incurred in connection with any Claim, but not, however, for
all of the total amount thereof, then the Company nevertheless shall indemnify
Indemnitee for the portion of such Expenses to which Indemnitee is entitled.

     6.   Mutual Acknowledgment.  Both the Company and Indemnitee acknowledge
          ---------------------                                              
that in certain instances Federal law or applicable public policy may prohibit
the Company from indemnifying its directors, officers, employees, agents, or
fiduciaries under this Agreement or otherwise.  Indemnitee understands and
acknowledges that the Company has undertaken or may be required in the future to
undertake with the Securities and Exchange Commission to submit the question of
indemnification to a court in certain circumstances for a determination of the
Company's right under public policy to indemnify Indemnitee.

     7.   Liability Insurance.  To the extent the Company maintains liability
          -------------------                                                
insurance applicable to directors, officers, employees, agents, or fiduciaries,
Indemnitee shall be covered by such policies in such a manner as to provide
Indemnitee the same rights and benefits as are accorded to the most favorably
insured of the Company's directors, if Indemnitee is a director; or of the
Company's officers, if Indemnitee is not a director of the Company but is an
officer; or of 
<PAGE>
 
the Company's key employees, agents, or fiduciaries, if Indemnitee is not an
officer or director but is a key employee, agent, or fiduciary.

     8.   Exceptions.  Any other provision herein to the contrary
          ----------                                             
notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement:

          (a)  Excluded Action or Omissions.  To indemnify Indemnitee for acts,
               ----------------------------                                    
omissions, or transactions from which Indemnitee may not be relieved of
liability under applicable law;

          (b)  Claims Initiated by Indemnitee.  To indemnify or advance expenses
               ------------------------------                                   
to Indemnitee with respect to Claims initiated or brought voluntarily by
Indemnitee and not by way of defense, except (i) with respect to actions or
proceedings brought to establish or enforce a right to indemnification under
this Agreement or any other agreement or insurance policy or under the Company's
Certificate of Incorporation or Bylaws now or hereafter in effect relating to
Claims for Indemnifiable Events, (ii) in specific cases if the Board of
Directors has approved the initiation or bringing of such Claim, or (iii) as
otherwise required under Section 145 of the Delaware General Corporation Law,
regardless of whether Indemnitee ultimately is determined to be entitled to such
indemnification, advance expense payment, or insurance recovery, as the case may
be;

          (c)  Lack of Good Faith.  To indemnify Indemnitee for any expenses
               ------------------                                           
incurred by Indemnitee with respect to any proceeding instituted by Indemnitee
to enforce or interpret this Agreement, if a court of competent jurisdiction
determines that each of the material assertions made by Indemnitee in such
proceeding was not made in good faith or was frivolous; or

          (d)  Claims Under Section 16(b).  To indemnify Indemnitee for expenses
               --------------------------                                       
and the payment of profits arising from the purchase and sale by Indemnitee of
securities in violation of Section 16(b) of the Securities Exchange Act of 1934,
as amended, or any similar successor statute.

     9.   Period of Limitations.  No legal action shall be brought and no cause
          ---------------------                                                
of action shall be asserted by or in the right of the Company against
Indemnitee, Indemnitee's estate, spouse, heirs, executors, or personal or legal
representatives after the expiration of two years from the date of accrual of
such cause of action, and any claim or cause of action of the Company shall be
extinguished and deemed released unless asserted by the timely filing of a legal
action within such two-year period; provided, however, that if any shorter
                                    --------  -------                     
period of limitations is otherwise applicable to any such cause of action, such
shorter period shall govern.

     10.  Construction of Certain Phrases.
          ------------------------------- 

          (a)  For purposes of this Agreement, references to the "Company" shall
include, in addition to the resulting corporation, any constituent corporation
(including any constituent of a constituent) absorbed in a consolidation or
merger which, if its separate existence had continued, would have had power and
authority to indemnify its directors, officers, employees, agents, or
<PAGE>
 
fiduciaries, so that if Indemnitee is or was a director, officer, employee,
agent, or fiduciary of such constituent corporation, or is or was serving at the
request of such constituent corporation as a director, officer, employee, agent,
or fiduciary of another corporation, partnership, joint venture, employee
benefit plan, trust, or other enterprise, Indemnitee shall stand in the same
position under the provisions of this Agreement with respect to the resulting or
surviving corporation as Indemnitee would have stood with respect to such
constituent corporation if its separate existence had continued.

          (b)  For purposes of this Agreement, references to "other enterprises"
shall include employee benefit plans; references to "fines" shall include any
excise taxes assessed on Indemnitee with respect to an employee benefit plan;
and references to "serving at the request of the Company" shall include any
service as a director, officer, employee, agent, or fiduciary of the Company
which imposes duties on, or involves services by, such director, officer,
employee, agent, or fiduciary with respect to an employee benefit plan, its
participants or its beneficiaries; and if Indemnitee acted in good faith and in
a manner Indemnitee reasonably believed to be in the interests of the
participants and beneficiaries of an employee benefit plan, then Indemnitee
shall be deemed to have acted in a manner "not opposed to the best interests of
the Company" as referred to in this Agreement.

          (c)  For purposes of this Agreement a "Change in Control" shall be
deemed to have occurred if (i) any "person" (as such term is used in Sections
13(d) and 14(d) of the Securities Exchange Act of 1934, as amended), other than
a trustee or other fiduciary holding securities under an employee benefit plan
of the Company or a corporation owned directly or indirectly by the stockholders
of the Company in substantially the same proportions as their ownership of stock
of the Company, (A) who is or becomes the beneficial owner, directly or
indirectly, of securities of the Company representing 10% or more of the
combined voting power of the Company's then outstanding Voting Securities
increases his beneficial ownership of such securities by 5% or more over the
percentage so owned by such person, or (B) becomes the "beneficial owner" (as
defined in Rule 13d-3 under said Act), directly or indirectly, of securities of
the Company representing more than 20% of the total voting power represented by
the Company's then outstanding Voting Securities, (ii) during any period of two
consecutive years, individuals who at the beginning of such period constitute
the Board of Directors of the Company and any new director whose election by the
Board of Directors or nomination for election by the Company's stockholders was
approved by a vote of at least two-thirds of the directors then still in office
who either were directors at the beginning of the period or whose election or
nomination for election was previously so approved cease for any reason to
constitute a majority thereof, or (iii) the stockholders of the Company approve
a merger or consolidation of the Company with any other corporation other than a
merger or consolidation which would result in the Voting Securities of the
Company outstanding immediately prior thereto continuing to represent (either by
remaining outstanding or by being converted into Voting Securities of the
surviving entity) at least 80% of the total voting power represented by the
Voting Securities of the Company or such surviving entity outstanding
immediately after such merger or consolidation, or the stockholders of the
Company approve a plan of complete liquidation of the 
<PAGE>
 
Company or an agreement for the sale or disposition by the Company (in one
transaction or a series of transactions) of all or substantially all of the
Company's assets.

          (d)  For purposes of this Agreement, "Independent Legal Counsel" shall
mean an attorney or firm of attorneys, selected in accordance with the
provisions of Section 1(c) hereof, who shall not have otherwise performed
services for the Company or Indemnitee within the last three years (other than
with respect to matters concerning the rights of Indemnitee under this
Agreement, or of other indemnitees under similar indemnity agreements).

          (e)  For purposes of this Agreement, a "Reviewing Party" shall mean
any appropriate person or body consisting of a member or members of the
Company's Board of Directors or any other person or body appointed by the Board
of Directors who is not a party to the particular Claim for which Indemnitee is
seeking indemnification, or Independent Legal Counsel.

          (f)  For purposes of this Agreement, "Voting Securities" shall mean
any securities of the Company that vote generally in the election of directors.

     11.  Counterparts.  This Agreement may be executed in one or more
          ------------                                                
counterparts, each of which shall constitute an original.

     12.  Binding Effect; Successors and Assigns.  This Agreement shall be
          --------------------------------------                          
binding upon and inure to the benefit of and be enforceable by the parties
hereto and their respective successors (including any direct or indirect
successor by purchase, merger, consolidation, or otherwise to all or
substantially all of the business and/or assets of the Company), assigns,
spouses, heirs, and personal and legal representatives.  The Company shall
require and cause any successor (whether direct or indirect by purchase, merger,
consolidation, or otherwise) to all, substantially all, or a substantial part of
the business and/or assets of the Company, by written agreement in form and
substance satisfactory to Indemnitee, expressly to assume and agree to perform
this Agreement in the same manner and to the same extent that the Company would
be required to perform if no such succession had taken place.  This Agreement
shall continue in effect regardless of whether Indemnitee continues to serve as
a director, officer, employee, agent, or fiduciary of the Company or of any
other enterprise at the Company's request.

     13.  Attorney's Fees.  In the event that any action is instituted by
          ---------------                                                
Indemnitee under this Agreement or under any liability insurance policies
maintained by the Company to enforce or interpret any of the terms hereof or
thereof, Indemnitee shall be entitled to be paid all Expenses incurred by
Indemnitee with respect to such action, regardless of whether Indemnitee is
ultimately successful in such action, and shall be entitled to the advancement
of Expenses with respect to such action, unless, as a part of such action, a
court of competent jurisdiction over such action determines that each of the
material assertions made by Indemnitee as a basis for such action was not made
in good faith or was frivolous.  In the event of an action instituted by or in
the name of the Company under this Agreement to enforce or interpret any of the
terms of this Agreement, Indemnitee shall be entitled to be paid all Expenses
incurred by Indemnitee in 
<PAGE>
 
defense of such action (including costs and expenses incurred with respect to
Indemnitee's counterclaims and cross-claims made in such action) and shall be
entitled to the advancement of Expenses with respect to such action, unless, as
a part of such action, a court having jurisdiction over such action determines
that each of Indemnitee's material defenses to such action was made in bad faith
or was frivolous.

     14.  Notice.  All notices and other communications required or permitted
          ------

and if to the Company at the address of its principal corporate offices
(attention: Secretary) or at such other address as such party may designate by
ten days' advance written notice to the other party hereto.

     15.  Consent to Jurisdiction.  The Company and Indemnitee each hereby
          -----------------------                                         
irrevocably consent to the jurisdiction of the courts of the State of Delaware
for all purposes in connection with any action or proceeding which arises out of
or relates to this Agreement and agree that any action instituted under this
Agreement shall be commenced, prosecuted, and continued only in the Court of
Chancery of the State of Delaware in and for New Castle County, which shall be
the exclusive and only proper forum adjudicating such a claim.

     16.  Severability.  The provisions of this Agreement shall be severable in
          ------------                                                         
the event that any of the provisions hereof (including any provision within a
single section, paragraph, or sentence) are held by a court of competent
jurisdiction to be invalid, void, or otherwise unenforceable, and the remaining
provisions shall remain enforceable to the fullest extent permitted by law.
Furthermore, to the fullest extent possible, the provisions of this Agreement
(including, without limitations, each portion of this Agreement containing any
provision held to be invalid, void, or otherwise unenforceable that is not
itself invalid, void, or unenforceable) shall be construed so as to give effect
to the intent manifested by the provision held invalid, illegal, or
unenforceable.

     17.  Choice of Law.  This Agreement shall be governed by and its provisions
          -------------                                                         
construed and enforced in accordance with the laws of the State of Delaware, as
applied to contracts between Delaware residents, entered into and to be
performed entirely within the State of Delaware, without regard to the conflict
of laws principles thereof.

     18.  Subrogation.  In the event of payment under this Agreement, the
          -----------                                                    
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of Indemnitee, who shall execute all documents required and shall do
all acts that may be necessary to secure such rights and to enable the Company
effectively to bring suit to enforce such rights.
<PAGE>
 
     19.  Amendment and Termination.  No amendment, modification, termination,
          -------------------------                                           
or cancellation of this Agreement shall be effective unless it is in writing
signed by both the parties hereto.  No waiver of any of the provisions of this
Agreement shall be deemed or shall constitute a waiver of any other provisions
hereof (whether or not similar) nor shall such waiver constitute a continuing
waiver.

     20.  Integration and Entire Agreement.  This Agreement sets forth the
          --------------------------------                                
entire understanding between the parties hereto and supersedes and merges all
previous written and oral negotiations, commitments, understandings, and
agreements relating to the subject matter hereof between the parties hereto.

     21.  No Construction as Employment Agreement.  Nothing contained in this
          ---------------------------------------                            
Agreement shall be construed as giving Indemnitee any right to be retained in
the employ of the Company or any of its subsidiaries or to serve on the Board of
Directors of the Company or any of its subsidiaries or to hold any other

                           INDEMNIFICATION AGREEMENT
                           -------------------------


     This Indemnification Agreement ("Agreement") is made and entered into as of
the 24th day of September, 1997, by and between CSG SYSTEMS INTERNATIONAL, INC.,
a Delaware corporation, and its wholly-owned subsidiary, CSG SYSTEMS, INC. (such
two corporations being collectively referred to herein as the "Company") and
JOHN P. POGGE ("Indemnitee").


                                   RECITALS:


     A.   The Company and Indemnitee recognize the continued difficulty in
obtaining liability insurance for its directors, officers, employees, agents,
and fiduciaries, the significant increases in the cost of such insurance and the
general reductions in the coverage of such insurance.

     B.   The Company and Indemnitee further recognize the substantial increase
in corporate litigation in general, subjecting directors, officers, employees,
agents, and fiduciaries to extensive litigation risks at the same time as the
availability and coverage of liability insurance has been severely reduced.

     C.   Indemnitee does not regard the current protection available as
adequate under the present circumstances, and Indemnitee and other directors,
officers, employees, agents, and fiduciaries of the Company may not be willing
to continue to serve in such capacities without additional protection.

     D.   The Company desires to attract and retain the services of highly
qualified individuals, such as Indemnitee, to serve the Company and, in part, in
order to induce Indemnitee to continue to provide services to the Company,
wishes to provide for the indemnification and advancing of expenses to
Indemnitee to the maximum extent permitted by law.

     E.   In view of the considerations set forth above, the Company desires
that Indemnitee be indemnified by the Company as set forth herein.

     NOW, THEREFORE, the Company and Indemnitee hereby agree as follows:

     1.   Indemnification.
          --------------- 

          (a)  Indemnification of Expenses.  The Company shall indemnify
               ---------------------------                              
Indemnitee to the fullest extent permitted by law if Indemnitee was or is or
becomes a party to or witness or other participant in, or is threatened to be
made a party to or witness or other participant in, any threatened, pending, or
completed action, suit, proceeding, or alternative dispute resolution mechanism,
or any hearing, inquiry, or investigation that Indemnitee in good faith believes
might lead to the institution of any such action, suit, proceeding, or
alternative dispute resolution mechanism, whether civil, criminal,
administrative, investigative, or other (hereinafter a "Claim") by reason of (or
arising in part out of) any event or occurrence related to the fact that
Indemnitee is 
<PAGE>
 
or was a director, officer, employee, agent, or fiduciary of the Company, or any
subsidiary of the Company, or is or was serving at the request of the Company as
a director, officer, employee, agent, or fiduciary of another corporation,
partnership, joint venture, trust, or other enterprise, or by reason of any
action or inaction on the part of Indemnitee while serving in such capacity
(hereinafter as "Indemnifiable Event") against any and all expenses (including
attorneys' fees and all other costs, expenses, and obligations incurred in
connection with investigating, defending, being a witness in or participating in
(including on appeal), or preparing to defend, be a witness in, or participate
in, any such action, suit, proceeding, alternative dispute resolution mechanism,
hearing, inquiry, or investigation), judgments, fines, penalties and amounts
paid in settlement (if such settlement is approved in advance by the Company,
which approval shall not be unreasonably withheld) of such Claim and any
federal, state, local, or foreign taxes imposed on Indemnitee as a result of the
actual or deemed receipt of any payments under this Agreement (collectively,
hereinafter "Expenses"), including all interest, assessments, and other charges
paid or payable in connection with or in respect of such Expenses. Such payment
of Expenses shall be made by the Company as soon as practicable but in any event
no later than five days after written demand by Indemnitee therefor is presented
to the Company.

          (b)  Reviewing Party.  Notwithstanding the foregoing, (i) the
               ---------------                                         
obligations of the Company under Section 1(a) shall be subject to the condition
that the Reviewing Party (as described in Section 10(e) hereof) shall not have
determined (in a written opinion, in any case in which the Independent Legal
Counsel referred to in Section 1(c) hereof is involved) that Indemnitee would
not be permitted to be indemnified under applicable law, and (ii) the obligation
of the Company to make an advance payment of Expenses to Indemnitee pursuant to
Section 2(a) (an "Expense Advance") shall be subject to the condition that, if,
when, and to the extent that the Reviewing Party determines that Indemnitee
would not be permitted to be so indemnified under applicable law, the Company
shall be entitled to be reimbursed by Indemnitee (who hereby agrees to reimburse
the Company) for all such amounts theretofore paid; provided, however, that if
Indemnitee has commenced or thereafter commences legal proceedings in a court of
competent jurisdiction to secure a determination that Indemnitee should be
indemnified under applicable law, any determination made by the Reviewing Party
that Indemnitee would not be permitted to be indemnified under applicable law
shall not be binding and Indemnitee shall not be required to reimburse the
Company for any Expense Advance until a final judicial determination is made
with respect thereto (as to which all rights of appeal therefrom have been
exhausted or lapsed).  Indemnitee's obligation to reimburse the Company for any
Expense Advance shall be unsecured, and no interest shall be charged thereon.
If there has not been a Change in Control (as defined in Section 10(c) hereof),
then the Reviewing Party shall be selected by the Board of Directors; and if
there has been such a Change in Control (other than a Change in Control which
has been approved by a majority of the Company's Board of Directors who were
directors immediately prior to such Change in Control), then the Reviewing Party
shall be the Independent Legal Counsel referred to in Section 1(c) hereof.  If
there has been no determination by the Reviewing Party or if the Reviewing Party
determines that Indemnitee substantively would not be permitted to be
indemnified in whole or in part under applicable law, then Indemnitee shall have
the right to commence litigation seeking an initial determination by the court
or challenging any such determination by the Reviewing Party or any aspect
thereof, including the legal or factual bases therefor, and the Company hereby
consents to service of process and to appear in any such proceeding.  Any
determination by the 
<PAGE>
 
Reviewing Party otherwise shall be conclusive and binding on the Company and
Indemnitee.

          (c)  Change in Control.  The Company agrees that if there is a Change
               -----------------                                               
in Control of the Company (other than a Change in Control which has been
approved by a majority of the Company's Board of Directors who were directors
immediately prior to such Change in Control) then, with respect to all matters
thereafter arising concerning the rights of Indemnitee to payments of Expenses
and Expense Advances under this Agreement or any other agreement under the
Company's Certificate of Incorporation or Bylaws as now or hereafter in effect,
Independent Legal Counsel (as defined in Section 10(d) hereof) shall be selected
by Indemnitee and approved by the Company (which approval shall not be
unreasonably withheld).  Such counsel, among other things, shall render its
written opinion to the Company and Indemnitee as to whether and to what extent
Indemnitee would be permitted to be indemnified under applicable law, and the
Company agrees to abide by such opinion.  The Company agrees to pay the
reasonable fees of the Independent Legal Counsel referred to above and to fully
indemnify such counsel against any and all expenses (including attorneys' fees),
claims, liabilities, and damages arising out of or relating to this Agreement or
its engagement pursuant hereto.

          (d)  Mandatory Payment of Expenses.  Notwithstanding any other
               -----------------------------                            
provision of this Agreement other than Section 9 hereof, to the extent that
Indemnitee has been successful on the merits or otherwise, including, without
limitation, the dismissal of an action without prejudice, in defense of any
action, suit, proceeding, inquiry, or investigation referred to in Section 1(a)
hereof or in the defense of any claim, issue, or matter therein, Indemnitee
shall be indemnified against all Expenses incurred by Indemnitee in connection
therewith.

     2.   Expenses; Indemnification Procedure.
          ----------------------------------- 

          (a)  Advancement of Expenses.  The Company shall advance all Expenses
               -----------------------                                         
incurred by Indemnitee.  The advances to be made hereunder shall be paid by the
Company to Indemnitee as soon as practicable but in any event no later than five
days after written demand by Indemnitee therefor to the Company.

          (b)  Notice/Cooperation by Indemnitee.  Indemnitee shall, as a
               --------------------------------                         
condition precedent to Indemnitee's right to be indemnified under this
Agreement, give the Company notice in writing as soon as practicable of any
Claim made against Indemnitee for which Indemnification will or could be sought
under this Agreement.  Notice to the Company shall be directed to the Chief
Executive Officer of the Company at the address shown on the signature page of
this Agreement (or such other address as the Company shall designate in writing
to Indemnitee).  In addition, Indemnitee shall give the Company such information
and cooperation as it may reasonably require and as shall be within Indemnitee's
power.

          (c)  No Presumptions; Burden of Proof.  For purposes of this
               --------------------------------                       
Agreement, the termination of any Claim by judgment, order, settlement (whether
with or without court approval), or conviction, or upon a plea of nolo
                                                                  ----
contendere, or its equivalent, shall not create a presumption that Indemnitee
- ----------                                                                   
did not meet any particular standard of conduct or have any particular belief or
that a court has determined that indemnification is not permitted by applicable
law.  In addition, neither 
<PAGE>
 
the failure of the Reviewing Party to have made a determination as to whether
Indemnitee has met any particular standard of conduct or had any particular
belief, nor an actual determination by the Reviewing Party that Indemnitee has
not met such standard of conduct or did not have such belief, prior to the
commencement of legal proceedings by Indemnitee to secure a judicial
determination that Indemnitee should be indemnified under applicable law, shall
be a defense to Indemnitee's claim or create a presumption that Indemnitee has
not met any particular standard of conduct or did not have any particular
belief. In connection with any determination by the Reviewing Party or otherwise
as to whether Indemnitee is entitled to be indemnified hereunder, the burden of
proof shall be on the Company to establish that Indemnitee is not so entitled.

          (d)  Notice to Insurers.  If, at the time of the receipt by the
               ------------------                                        
Company of a notice of a Claim pursuant to Section 2(b) hereof, the Company has
liability insurance in effect which may cover such Claim, the Company shall give
prompt notice of the commencement of such Claim to the insurers in accordance
with the procedures set forth in the respective policies.  The Company shall
thereafter take all necessary or desirable action to cause such insurers to pay,
on behalf of Indemnitee, all amounts payable as a result of such action, suit,
proceeding, inquiry, or investigation in accordance with the terms of such
policies.

          (e)  Selection of Counsel.  In the event the Company shall be
               --------------------                                    
obligated hereunder to pay the Expenses of any Claim, the Company, if
appropriate, shall be entitled to assume the defense of such Claim with counsel
approved by Indemnitee, upon the delivery to Indemnitee of written notice of its
election so to do.  After delivery of such notice, approval of such counsel by
Indemnitee and the retention of such counsel by the Company, the Company will
not be liable to Indemnitee under this Agreement for any fees of counsel
subsequently incurred by Indemnitee with respect to the same Claim; provided
that, (i) Indemnitee shall have the right to employ Indemnitee's counsel in any
such Claim at Indemnitee's expense and (ii) if (A) the employment of counsel by
Indemnitee has been previously authorized by the Company, (B) Indemnitee shall
have reasonably concluded that there may be a conflict of interest between the
Company and Indemnitee in the conduct of any such defense, or (C) the Company
shall not continue to retain such counsel to defend such Claim, then the fees
and expenses of Indemnitee's counsel shall be at the expense of the Company.

     3.   Additional Indemnification Rights; Nonexclusivity.
          ------------------------------------------------- 


          (a)  Scope.  The Company hereby agrees to indemnify Indemnitee to the
               -----                                                           
fullest extent permitted by law, notwithstanding that such indemnification is
not specifically authorized by the other provisions of this Agreement, the
Company's Certificate of Incorporation, the Company's Bylaws, or by statute.  In
the event of any change after the date of this Agreement in any applicable law,
statute, or rule which expands the right of a Delaware corporation to indemnify
a member of its Board of Directors or an officer, employee, agent, or fiduciary,
it is the intent of the parties hereto that Indemnitee shall enjoy by this
Agreement the greater benefits afforded by such change.  In the event of any
change in any applicable law, statute, or rule which narrows the right of a
Delaware corporation to indemnify a member of its Board of Directors or an
officer, employee, agent, or fiduciary, such change, to the extent not otherwise
required by such law, statute, or rule to be applied to this Agreement, shall
have no effect on this Agreement or the parties' rights and obligations
hereunder except as set forth in Section 8(a) hereof.


          (b)  Nonexclusivity.  The indemnification provided by this Agreement
               --------------                                                 
shall be in addition to any rights to which Indemnitee may be entitled under the
Company's Certificate of Incorporation, its Bylaws, any agreement, any vote of
stockholders or disinterested directors, the General Corporation Law of the
State of Delaware, or otherwise.  The indemnification provided under this
Agreement shall continue as to Indemnitee for any action taken or not taken by
Indemnitee while serving in an indemnified capacity even though Indemnitee may
have ceased to serve in such capacity.

     4.   No Duplication of Payments.  The Company shall not be liable under
          --------------------------                                        
this Agreement to make any payment in connection with any Claim made against
Indemnitee to the extent Indemnitee has otherwise actually received payment
(under any insurance policy, Certificate of Incorporation, Bylaw, or otherwise)
of the amounts otherwise indemnifiable hereunder.

     5.   Partial Indemnification.  If Indemnitee is entitled under any
          -----------------------                                      
provision of this Agreement to indemnification by the Company for some or a
portion of Expenses incurred in connection with any Claim, but not, however, for
all of the total amount thereof, then the Company nevertheless shall indemnify
Indemnitee for the portion of such Expenses to which Indemnitee is entitled.

     6.   Mutual Acknowledgment.  Both the Company and Indemnitee acknowledge
          ---------------------                                              
that in certain instances Federal law or applicable public policy may prohibit
the Company from indemnifying its directors, officers, employees, agents, or
fiduciaries under this Agreement or otherwise.  Indemnitee understands and
acknowledges that the Company has undertaken or may be required in the future to
undertake with the Securities and Exchange Commission to submit the question of
indemnification to a court in certain circumstances for a determination of the
Company's right under public policy to indemnify Indemnitee.

     7.   Liability Insurance.  To the extent the Company maintains liability
          -------------------                                                
insurance applicable to directors, officers, employees, agents, or fiduciaries,
Indemnitee shall be covered by such policies in such a manner as to provide
Indemnitee the same rights and benefits as are 
<PAGE>
 
accorded to the most favorably insured of the Company's directors, if Indemnitee
is a director; or of the Company's officers, if Indemnitee is not a director of
the Company but is an officer; or of the Company's key employees, agents, or
fiduciaries, if Indemnitee is not an officer or director but is a key employee,
agent, or fiduciary.


     8.   Exceptions.  Any other provision herein to the contrary
          ----------                                             
notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement:

          (a)  Excluded Action or Omissions.  To indemnify Indemnitee for acts,
               ----------------------------                                    
omissions, or transactions from which Indemnitee may not be relieved of
liability under applicable law;


          (b)  Claims Initiated by Indemnitee.  To indemnify or advance expenses
               ------------------------------                                   
to Indemnitee with respect to Claims initiated or brought voluntarily by
Indemnitee and not by way of defense, except (i) with respect to actions or
proceedings brought to establish or enforce a right to indemnification under
this Agreement or any other agreement or insurance policy or under the Company's
Certificate of Incorporation or Bylaws now or hereafter in effect relating to
Claims for Indemnifiable Events, (ii) in specific cases if the Board of
Directors has approved the initiation or bringing of such Claim, or (iii) as
otherwise required under Section 145 of the Delaware General Corporation Law,
regardless of whether Indemnitee ultimately is determined to be entitled to such
indemnification, advance expense payment, or insurance recovery, as the case may
be;

          (c)  Lack of Good Faith.  To indemnify Indemnitee for any expenses
               ------------------                                           
incurred by Indemnitee with respect to any proceeding instituted by Indemnitee
to enforce or interpret this Agreement, if a court of competent jurisdiction
determines that each of the material assertions made by Indemnitee in such
proceeding was not made in good faith or was frivolous; or

          (d)  Claims Under Section 16(b).  To indemnify Indemnitee for expenses
               --------------------------                                       
and the payment of profits arising from the purchase and sale by Indemnitee of
securities in violation of Section 16(b) of the Securities Exchange Act of 1934,
as amended, or any similar successor statute.

     9.   Period of Limitations.  No legal action shall be brought and no cause
          ---------------------                                                
of action shall be asserted by or in the right of the Company against
Indemnitee, Indemnitee's estate, spouse, heirs, executors, or personal or legal
representatives after the expiration of two years from the date of accrual of
such cause of action, and any claim or cause of action of the Company shall be
extinguished and deemed released unless asserted by the timely filing of a legal
action within such two-year period; provided, however, that if any shorter
                                    --------  -------                     
period of limitations is otherwise applicable to any such cause of action, such
shorter period shall govern.

     10.  Construction of Certain Phrases.
          ------------------------------- 

          (a)  For purposes of this Agreement, references to the "Company" shall
include, in addition to the resulting corporation, any constituent corporation
(including any constituent of a constituent) absorbed in a consolidation or
merger which, if its separate existence had continued, would have had power and
authority to indemnify its directors, officers, employees, agents, or
<PAGE>
 
fiduciaries, so that if Indemnitee is or was a director, officer, employee,
agent, or fiduciary of such constituent corporation, or is or was serving at the
request of such constituent corporation as a director, officer, employee, agent,
or fiduciary of another corporation, partnership, joint venture, employee
benefit plan, trust, or other enterprise, Indemnitee shall stand in the same
position under the provisions of this Agreement with respect to the resulting or
surviving corporation as Indemnitee would have stood with respect to such
constituent corporation if its separate existence had continued.

          (b)  For purposes of this Agreement, references to "other enterprises"
shall include employee benefit plans; references to "fines" shall include any
excise taxes assessed on Indemnitee with respect to an employee benefit plan;
and references to "serving at the request of the Company" shall include any
service as a director, officer, employee, agent, or fiduciary of the Company
which imposes duties on, or involves services by, such director, officer,
employee, agent, or fiduciary with respect to an employee benefit plan, its
participants or its beneficiaries; and if Indemnitee acted in good faith and in
a manner Indemnitee reasonably believed to be in the interests of the
participants and beneficiaries of an employee benefit plan, then Indemnitee
shall be deemed to have acted in a manner "not opposed to the best interests of
the Company" as referred to in this Agreement.

          (c)  For purposes of this Agreement a "Change in Control" shall be
deemed to have occurred if (i) any "person" (as such term is used in Sections
13(d) and 14(d) of the Securities Exchange Act of 1934, as amended), other than
a trustee or other fiduciary holding securities under an employee benefit plan
of the Company or a corporation owned directly or indirectly by the stockholders
of the Company in substantially the same proportions as their ownership of stock
of the Company, (A) who is or becomes the beneficial owner, directly or
indirectly, of securities of the Company representing 10% or more of the
combined voting power of the Company's then outstanding Voting Securities
increases his beneficial ownership of such securities by 5% or more over the
percentage so owned by such person, or (B) becomes the "beneficial owner" (as
defined in Rule 13d-3 under said Act), directly or indirectly, of securities of
the Company representing more than 20% of the total voting power represented by
the Company's then outstanding Voting Securities, (ii) during any period of two
consecutive years, individuals who at the beginning of such period constitute
the Board of Directors of the Company and any new director whose election by the
Board of Directors or nomination for election by the Company's stockholders was
approved by a vote of at least two-thirds of the directors then still in office
who either were directors at the beginning of the period or whose election or
nomination for election was previously so approved cease for any reason to
constitute a majority thereof, or (iii) the stockholders of the Company approve
a merger or consolidation of the Company with any other corporation other than a
merger or consolidation which would result in the Voting Securities of the
Company outstanding immediately prior thereto continuing to represent (either by
remaining outstanding or by being converted into Voting Securities of the
surviving entity) at least 80% of the total voting power represented by the
Voting Securities of the Company or such surviving entity outstanding
immediately after such merger or consolidation, or the stockholders of the
Company approve a plan of complete liquidation of the Company or an agreement
for the sale or disposition by the Company (in one transaction or a series of
transactions) of all or substantially all of the Company's assets.

          (d)  For purposes of this Agreement, "Independent Legal Counsel" shall
mean an attorney or firm of attorneys, selected in accordance with the
provisions of Section 1(c) hereof, who 
<PAGE>
 
shall not have otherwise performed services for the Company or Indemnitee within
the last three years (other than with respect to matters concerning the rights
of Indemnitee under this Agreement, or of other indemnitees under similar
indemnity agreements).

          (e)  For purposes of this Agreement, a "Reviewing Party" shall mean
any appropriate person or body consisting of a member or members of the
Company's Board of Directors or any other person or body appointed by the Board
of Directors who is not a party to the particular Claim for which Indemnitee is
seeking indemnification, or Independent Legal Counsel.

          (f)  For purposes of this Agreement, "Voting Securities" shall mean
any securities of the Company that vote generally in the election of directors.

     11.  Counterparts.  This Agreement may be executed in one or more
          ------------                                                
counterparts, each of which shall constitute an original.

     12.  Binding Effect; Successors and Assigns.  This Agreement shall be
          --------------------------------------                          
binding upon and inure to the benefit of and be enforceable by the parties
hereto and their respective successors (including any direct or indirect
successor by purchase, merger, consolidation, or otherwise to all or
substantially all of the business and/or assets of the Company), assigns,
spouses, heirs, and personal and legal representatives.  The Company shall
require and cause any successor (whether direct or indirect by purchase, merger,
consolidation, or otherwise) to all, substantially all, or a substantial part of
the business and/or assets of the Company, by written agreement in form and
substance satisfactory to Indemnitee, expressly to assume and agree to perform
this Agreement in the same manner and to the same extent that the Company would
be required to perform if no such succession had taken place.  This Agreement
shall continue in effect regardless of whether Indemnitee continues to serve as
a director, officer, employee, agent, or fiduciary of the Company or of any
other enterprise at the Company's request.


     13.  Attorney's Fees.  In the event that any action is instituted by
          ---------------                                                
Indemnitee under this Agreement or under any liability insurance policies
maintained by the Company to enforce or interpret any of the terms hereof or
thereof, Indemnitee shall be entitled to be paid all Expenses incurred by
Indemnitee with respect to such action, regardless of whether Indemnitee is
ultimately successful in such action, and shall be entitled to the advancement
of Expenses with respect to such action, unless, as a part of such action, a
court of competent jurisdiction over such action determines that each of the
material assertions made by Indemnitee as a basis for such action was not made
in good faith or was frivolous.  In the event of an action instituted by or in
the name of the Company under this Agreement to enforce or interpret any of the
terms of this Agreement, Indemnitee shall be entitled to be paid all Expenses
incurred by Indemnitee in defense of such action (including costs and expenses
incurred with respect to Indemnitee's counterclaims and cross-claims made in
such action) and shall be entitled to the advancement of Expenses with respect
to such action, unless, as a part of such action, a court having jurisdiction
over such action determines that each of Indemnitee's material defenses to such
action was made in bad faith or was frivolous.

     14.  Notice.  All notices and other communications required or permitted
          ------                                                             
hereunder shall be in writing, shall be effective when given, and shall in any
event be deemed to be given (a) five 
<PAGE>
 
days after deposit with the U.S. Postal Service or other applicable postal
service, if delivered by first class mail postage prepaid, (b) upon delivery, if
delivered by hand, (c) one business day after the business day of deposit with
Federal Express or similar overnight courier, freight prepaid, or (d) one day
after the business day of delivery by facsimile transmission, if delivered by
facsimile transmission, with a copy by first class mail postage prepaid, and
shall be addressed if to the Indemnitee at the Indemnitee's address as set forth
beneath his signature to this Agreement and if to the Company at the address of
its principal corporate offices (attention: Secretary) or at such other address
as such party may designate by ten days' advance written notice to the other
party hereto.

     15.  Consent to Jurisdiction.  The Company and Indemnitee each hereby
          -----------------------                                         
irrevocably consent to the jurisdiction of the courts of the State of Delaware
for all purposes in connection with any action or proceeding which arises out of
or relates to this Agreement and agree that any action instituted under this
Agreement shall be commenced, prosecuted, and continued only in the Court of
Chancery of the State of Delaware in and for New Castle County, which shall be
the exclusive and only proper forum adjudicating such a claim.

     16.  Severability.  The provisions of this Agreement shall be severable in
          ------------                                                         
the event that any of the provisions hereof (including any provision within a
single section, paragraph, or sentence) are held by a court of competent
jurisdiction to be invalid, void, or otherwise unenforceable, and the remaining
provisions shall remain enforceable to the fullest extent permitted by law.
Furthermore, to the fullest extent possible, the provisions of this Agreement
(including, without limitations, each portion of this Agreement containing any
provision held to be invalid, void, or otherwise unenforceable that is not
itself invalid, void, or unenforceable) shall be construed so as to give effect
to the intent manifested by the provision held invalid, illegal, or
unenforceable.

     17.  Choice of Law.  This Agreement shall be governed by and its provisions
          -------------                                                         
construed and enforced in accordance with the laws of the State of Delaware, as
applied to contracts between Delaware residents, entered into and to be
performed entirely within the State of Delaware, without regard to the conflict
of laws principles thereof.

     18.  Subrogation.  In the event of payment under this Agreement, the
          -----------                                                    
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of Indemnitee, who shall execute all documents required and shall do
all acts that may be necessary to secure such rights and to enable the Company
effectively to bring suit to enforce such rights.

          -------------------------                                           
or cancellation of this Agreement shall be effective unless it is in writing
signed by both the parties hereto.  No waiver of any of the provisions of this

                           INDEMNIFICATION AGREEMENT
                           -------------------------

     This Indemnification Agreement ("Agreement") is made and entered into as of
the 18th day of November, 1997, by and between CSG SYSTEMS INTERNATIONAL, INC.,
a Delaware corporation, and its wholly-owned subsidiary, CSG SYSTEMS, INC. (such
two corporations being collectively referred to herein as the "Company") and
JANICE OBUCHOWSKI ("Indemnitee").

                                   RECITALS:

     A.   The Company and Indemnitee recognize the continued difficulty in
obtaining liability insurance for its directors, officers, employees, agents,
and fiduciaries, the significant increases in the cost of such insurance and the
general reductions in the coverage of such insurance.

     B.   The Company and Indemnitee further recognize the substantial increase
in corporate litigation in general, subjecting directors, officers, employees,
agents, and fiduciaries to extensive litigation risks at the same time as the
availability and coverage of liability insurance has been severely reduced.

     C.   Indemnitee does not regard the current protection available as
adequate under the present circumstances, and Indemnitee and other directors,
officers, employees, agents, and fiduciaries of the Company may not be willing
to continue to serve in such capacities without additional protection.

     D.   The Company desires to attract and retain the services of highly
qualified individuals, such as Indemnitee, to serve the Company and, in part, in
order to induce Indemnitee to continue to provide services to the Company,
wishes to provide for the indemnification and advancing of expenses to
Indemnitee to the maximum extent permitted by law.

     E.   In view of the considerations set forth above, the Company desires
that Indemnitee be indemnified by the Company as set forth herein.

     NOW, THEREFORE, the Company and Indemnitee hereby agree as follows:

     1.   Indemnification.
          --------------- 

          (a)  Indemnification of Expenses.  The Company shall indemnify
               ---------------------------                              
Indemnitee to the fullest extent permitted by law if Indemnitee was or is or
becomes a party to or witness or other participant in, or is threatened to be
made a party to or witness or other participant in, any threatened, pending, or
completed action, suit, proceeding, or alternative dispute resolution mechanism,
or any hearing, inquiry, or investigation that Indemnitee in good faith believes
might 
<PAGE>
 
lead to the institution of any such action, suit, proceeding, or alternative
dispute resolution mechanism, whether civil, criminal, administrative,
investigative, or other (hereinafter a "Claim") by reason of (or arising in part
out of) any event or occurrence related to the fact that Indemnitee is or was a
director, officer, employee, agent, or fiduciary of the Company, or any
subsidiary of the Company, or is or was serving at the request of the Company as
a director, officer, employee, agent, or fiduciary of another corporation,
partnership, joint venture, trust, or other enterprise, or by reason of any
action or inaction on the part of Indemnitee while serving in such capacity
(hereinafter as "Indemnifiable Event") against any and all expenses (including
attorneys' fees and all other costs, expenses, and obligations incurred in
connection with investigating, defending, being a witness in or participating in
(including on appeal), or preparing to defend, be a witness in, or participate
in, any such action, suit, proceeding, alternative dispute resolution mechanism,
hearing, inquiry, or investigation), judgments, fines, penalties and amounts
paid in settlement (if such settlement is approved in advance by the Company,
which approval shall not be unreasonably withheld) of such Claim and any
federal, state, local, or foreign taxes imposed on Indemnitee as a result of the
actual or deemed receipt of any payments under this Agreement (collectively,
hereinafter "Expenses"), including all interest, assessments, and other charges
paid or payable in connection with or in respect of such Expenses. Such payment
of Expenses shall be made by the Company as soon as practicable but in any event
no later than five days after written demand by Indemnitee therefor is presented
to the Company.

          (b)  Reviewing Party.  Notwithstanding the foregoing, (i) the
               ---------------                                         
obligations of the Company under Section 1(a) shall be subject to the condition
that the Reviewing Party (as described in Section 10(e) hereof) shall not have
determined (in a written opinion, in any case in which the Independent Legal
Counsel referred to in Section 1(c) hereof is involved) that Indemnitee would
not be permitted to be indemnified under applicable law, and (ii) the obligation
of the Company to make an advance payment of Expenses to Indemnitee pursuant to
Section 2(a) (an "Expense Advance") shall be subject to the condition that, if,
when, and to the extent that the Reviewing Party determines that Indemnitee
would not be permitted to be so indemnified under applicable law, the Company
shall be entitled to be reimbursed by Indemnitee (who hereby agrees to reimburse
the Company) for all such amounts theretofore paid; provided, however, that if
Indemnitee has commenced or thereafter commences legal proceedings in a court of
competent jurisdiction to secure a determination that Indemnitee should be
indemnified under applicable law, any determination made by the Reviewing Party
that Indemnitee would not be permitted to be indemnified under applicable law
shall not be binding and Indemnitee shall not be required to reimburse the
Company for any Expense Advance until a final judicial determination is made
with respect thereto (as to which all rights of appeal therefrom have been
exhausted or lapsed).  Indemnitee's obligation to reimburse the Company for any
Expense Advance shall be unsecured, and no interest shall be charged thereon.
If there has not been a Change in Control (as defined in Section 10(c) hereof),
then the Reviewing Party shall be selected by the Board of Directors; and if
there has been such a Change in Control (other than a Change in Control which
has been approved by a majority of the Company's Board of Directors who were
directors immediately prior to such Change in Control), then the Reviewing Party
shall be the Independent Legal Counsel referred to in Section 1(c) hereof.  If
there has been no determination by the Reviewing Party or if the Reviewing Party
determines that Indemnitee 
<PAGE>
 
substantively would not be permitted to be indemnified in whole or in part under
applicable law, then Indemnitee shall have the right to commence litigation
seeking an initial determination by the court or challenging any such
determination by the Reviewing Party or any aspect thereof, including the legal
or factual bases therefor, and the Company hereby consents to service of process
and to appear in any such proceeding. Any determination by the Reviewing Party
otherwise shall be conclusive and binding on the Company and Indemnitee.

          (c)  Change in Control.  The Company agrees that if there is a Change
               -----------------                                               
in Control of the Company (other than a Change in Control which has been
approved by a majority of the Company's Board of Directors who were directors
immediately prior to such Change in Control) then, with respect to all matters
thereafter arising concerning the rights of Indemnitee to payments of Expenses
and Expense Advances under this Agreement or any other agreement under the
Company's Certificate of Incorporation or Bylaws as now or hereafter in effect,
Independent Legal Counsel (as defined in Section 10(d) hereof) shall be selected
by Indemnitee and approved by the Company (which approval shall not be
unreasonably withheld).  Such counsel, among other things, shall render its
written opinion to the Company and Indemnitee as to whether and to what extent
Indemnitee would be permitted to be indemnified under applicable law, and the
Company agrees to abide by such opinion.  The Company agrees to pay the
reasonable fees of the Independent Legal Counsel referred to above and to fully
indemnify such counsel against any and all expenses (including attorneys' fees),
claims, liabilities, and damages arising out of or relating to this Agreement or
its engagement pursuant hereto.

          (d)  Mandatory Payment of Expenses.  Notwithstanding any other
               -----------------------------                            
provision of this Agreement other than Section 9 hereof, to the extent that
Indemnitee has been successful on the merits or otherwise, including, without
limitation, the dismissal of an action without prejudice, in defense of any
action, suit, proceeding, inquiry, or investigation referred to in Section 1(a)
hereof or in the defense of any claim, issue, or matter therein, Indemnitee
shall be indemnified against all Expenses incurred by Indemnitee in connection
therewith.

     2.   Expenses; Indemnification Procedure.
          ----------------------------------- 

          (a) Advancement of Expenses.  The Company shall advance all Expenses
              -----------------------                                         
incurred by Indemnitee.  The advances to be made hereunder shall be paid by the
Company to Indemnitee as soon as practicable but in any event no later than five
days after written demand by Indemnitee therefor to the Company.

          (b)  Notice/Cooperation by Indemnitee.  Indemnitee shall, as a
               --------------------------------                         
condition precedent to Indemnitee's right to be indemnified under this
Agreement, give the Company notice in writing as soon as practicable of any
Claim made against Indemnitee for which Indemnification will or could be sought
under this Agreement.  Notice to the Company shall be directed to the Chief
Executive Officer of the Company at the address shown on the signature page of
this Agreement (or such other address as the Company shall designate in writing
to Indemnitee).  In addition, Indemnitee shall give the Company such information
and cooperation as it may reasonably require and as shall be within Indemnitee's
power.
<PAGE>
 
          (c)  No Presumptions; Burden of Proof.  For purposes of this
               --------------------------------                       
Agreement, the termination of any Claim by judgment, order, settlement (whether
with or without court approval), or conviction, or upon a plea of nolo
                                                                  ----
contendere, or its equivalent, shall not create a presumption that Indemnitee
- ----------                                                                   
did not meet any particular standard of conduct or have any particular belief or
that a court has determined that indemnification is not permitted by applicable
law.  In addition, neither the failure of the Reviewing Party to have made a
determination as to whether Indemnitee has met any particular standard of
conduct or had any particular belief, nor an actual determination by the
Reviewing Party that Indemnitee has not met such standard of conduct or did not
have such belief, prior to the commencement of legal proceedings by Indemnitee
to secure a judicial determination that Indemnitee should be indemnified under
applicable law, shall be a defense to Indemnitee's claim or create a presumption
that Indemnitee has not met any particular standard of conduct or did not have
any particular belief.  In connection with any determination by the Reviewing
Party or otherwise as to whether Indemnitee is entitled to be indemnified
hereunder, the burden of proof shall be on the Company to establish that
Indemnitee is not so entitled.

          (d)  Notice to Insurers.  If, at the time of the receipt by the
               ------------------                                        
Company of a notice of a Claim pursuant to Section 2(b) hereof, the Company has
liability insurance in effect which may cover such Claim, the Company shall give
prompt notice of the commencement of such Claim to the insurers in accordance
with the procedures set forth in the respective policies.  The Company shall
thereafter take all necessary or desirable action to cause such insurers to pay,
on behalf of Indemnitee, all amounts payable as a result of such action, suit,
proceeding, inquiry, or investigation in accordance with the terms of such
policies.

          (e)  Selection of Counsel.  In the event the Company shall be
               --------------------                                    
obligated hereunder to pay the Expenses of any Claim, the Company, if
appropriate, shall be entitled to assume the defense of such Claim with counsel
approved by Indemnitee, upon the delivery to Indemnitee of written notice of its
election so to do.  After delivery of such notice, approval of such counsel by
Indemnitee and the retention of such counsel by the Company, the Company will
not be liable to Indemnitee under this Agreement for any fees of counsel
subsequently incurred by Indemnitee with respect to the same Claim; provided
that, (i) Indemnitee shall have the right to employ Indemnitee's counsel in any
such Claim at Indemnitee's expense and (ii) if (A) the employment of counsel by
Indemnitee has been previously authorized by the Company, (B) Indemnitee shall
have reasonably concluded that there may be a conflict of interest between the
Company and Indemnitee in the conduct of any such defense, or (C) the Company
shall not continue to retain such counsel to defend such Claim, then the fees
and expenses of Indemnitee's counsel shall be at the expense of the Company.

     3.   Additional Indemnification Rights; Nonexclusivity.
          ------------------------------------------------- 

          (a)  Scope.  The Company hereby agrees to indemnify Indemnitee to the
               -----                                                           
fullest extent permitted by law, notwithstanding that such indemnification is
not specifically authorized by the other provisions of this Agreement, the
Company's Certificate of Incorporation, the 
<PAGE>
 
Company's Bylaws, or by statute. In the event of any change after the date of
this Agreement in any applicable law, statute, or rule which expands the right
of a Delaware corporation to indemnify a member of its Board of Directors or an
officer, employee, agent, or fiduciary, it is the intent of the parties hereto
that Indemnitee shall enjoy by this Agreement the greater benefits afforded by
such change. In the event of any change in any applicable law, statute, or rule
which narrows the right of a Delaware corporation to indemnify a member of its
Board of Directors or an officer, employee, agent, or fiduciary, such change, to
the extent not otherwise required by such law, statute, or rule to be applied to
this Agreement, shall have no effect on this Agreement or the parties' rights
and obligations hereunder except as set forth in Section 8(a) hereof.

          (b)  Nonexclusivity.  The indemnification provided by this Agreement
               --------------                                                 
shall be in addition to any rights to which Indemnitee may be entitled under the
Company's Certificate of Incorporation, its Bylaws, any agreement, any vote of
stockholders or disinterested directors, the General Corporation Law of the
State of Delaware, or otherwise.  The indemnification provided under this
Agreement shall continue as to Indemnitee for any action taken or not taken by
Indemnitee while serving in an indemnified capacity even though Indemnitee may
have ceased to serve in such capacity.

     4.   No Duplication of Payments.  The Company shall not be liable under
          --------------------------                                        
this Agreement to make any payment in connection with any Claim made against
Indemnitee to the extent Indemnitee has otherwise actually received payment
(under any insurance policy, Certificate of Incorporation, Bylaw, or otherwise)
of the amounts otherwise indemnifiable hereunder.

     5.   Partial Indemnification.  If Indemnitee is entitled under any
          -----------------------                                      
provision of this Agreement to indemnification by the Company for some or a
portion of Expenses incurred in connection with any Claim, but not, however, for
all of the total amount thereof, then the Company nevertheless shall indemnify
Indemnitee for the portion of such Expenses to which Indemnitee is entitled.

     6.   Mutual Acknowledgment.  Both the Company and Indemnitee acknowledge
          ---------------------                                              
that in certain instances Federal law or applicable public policy may prohibit
the Company from indemnifying its directors, officers, employees, agents, or
fiduciaries under this Agreement or otherwise.  Indemnitee understands and
acknowledges that the Company has undertaken or may be required in the future to
undertake with the Securities and Exchange Commission to submit the question of
indemnification to a court in certain circumstances for a determination of the
Company's right under public policy to indemnify Indemnitee.

     7.   Liability Insurance.  To the extent the Company maintains liability
          -------------------                                                
insurance applicable to directors, officers, employees, agents, or fiduciaries,
Indemnitee shall be covered by such policies in such a manner as to provide
Indemnitee the same rights and benefits as are accorded to the most favorably
insured of the Company's directors, if Indemnitee is a director; or of the
Company's officers, if Indemnitee is not a director of the Company but is an
officer; or of
<PAGE>
 
the Company's key employees, agents, or fiduciaries, if Indemnitee is not an
officer or director but is a key employee, agent, or fiduciary.

     8.   Exceptions.  Any other provision herein to the contrary
          ----------                                             
notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement:

          (a)  Excluded Action or Omissions.  To indemnify Indemnitee for acts,
               ----------------------------                                    
omissions, or transactions from which Indemnitee may not be relieved of
liability under applicable law;

          (b)  Claims Initiated by Indemnitee.  To indemnify or advance expenses
               ------------------------------                                   
to Indemnitee with respect to Claims initiated or brought voluntarily by
Indemnitee and not by way of defense, except (i) with respect to actions or
proceedings brought to establish or enforce a right to indemnification under
this Agreement or any other agreement or insurance policy or under the Company's
Certificate of Incorporation or Bylaws now or hereafter in effect relating to
Claims for Indemnifiable Events, (ii) in specific cases if the Board of
Directors has approved the initiation or bringing of such Claim, or (iii) as
otherwise required under Section 145 of the Delaware General Corporation Law,
regardless of whether Indemnitee ultimately is determined to be entitled to such
indemnification, advance expense payment, or insurance recovery, as the case may
be;

          (c)  Lack of Good Faith.  To indemnify Indemnitee for any expenses
               ------------------                                           
incurred by Indemnitee with respect to any proceeding instituted by Indemnitee
to enforce or interpret this Agreement, if a court of competent jurisdiction
determines that each of the material assertions made by Indemnitee in such
proceeding was not made in good faith or was frivolous; or

          (d)  Claims Under Section 16(b).  To indemnify Indemnitee for expenses
               --------------------------                                       
and the payment of profits arising from the purchase and sale by Indemnitee of
securities in violation of Section 16(b) of the Securities Exchange Act of 1934,
as amended, or any similar successor statute.

     9.   Period of Limitations.  No legal action shall be brought and no cause
          ---------------------                                                
of action shall be asserted by or in the right of the Company against
Indemnitee, Indemnitee's estate, spouse, heirs, executors, or personal or legal
representatives after the expiration of two years from the date of accrual of
such cause of action, and any claim or cause of action of the Company shall be
extinguished and deemed released unless asserted by the timely filing of a legal
action within such two-year period; provided, however, that if any shorter
                                    --------  -------                     
period of limitations is otherwise applicable to any such cause of action, such
shorter period shall govern.

     10.  Construction of Certain Phrases.
          ------------------------------- 

          (a)  For purposes of this Agreement, references to the "Company" shall
include, in addition to the resulting corporation, any constituent corporation
(including any constituent of a constituent) absorbed in a consolidation or
merger which, if its separate existence had continued, would have had power and
authority to indemnify its directors, officers, employees, agents, or
<PAGE>
 
fiduciaries, so that if Indemnitee is or was a director, officer, employee,
agent, or fiduciary of such constituent corporation, or is or was serving at the
request of such constituent corporation as a director, officer, employee, agent,
or fiduciary of another corporation, partnership, joint venture, employee
benefit plan, trust, or other enterprise, Indemnitee shall stand in the same
position under the provisions of this Agreement with respect to the resulting or
surviving corporation as Indemnitee would have stood with respect to such
constituent corporation if its separate existence had continued.

          (b)  For purposes of this Agreement, references to "other enterprises"
shall include employee benefit plans; references to "fines" shall include any
excise taxes assessed on Indemnitee with respect to an employee benefit plan;
and references to "serving at the request of the Company" shall include any
service as a director, officer, employee, agent, or fiduciary of the Company
which imposes duties on, or involves services by, such director, officer,
employee, agent, or fiduciary with respect to an employee benefit plan, its
participants or its beneficiaries; and if Indemnitee acted in good faith and in
a manner Indemnitee reasonably believed to be in the interests of the
participants and beneficiaries of an employee benefit plan, then Indemnitee
shall be deemed to have acted in a manner "not opposed to the best interests of
the Company" as referred to in this Agreement.

          (c)  For purposes of this Agreement a "Change in Control" shall be
deemed to have occurred if (i) any "person" (as such term is used in Sections
13(d) and 14(d) of the Securities Exchange Act of 1934, as amended), other than
a trustee or other fiduciary holding securities under an employee benefit plan
of the Company or a corporation owned directly or indirectly by the stockholders
of the Company in substantially the same proportions as their ownership of stock
of the Company, (A) who is or becomes the beneficial owner, directly or
indirectly, of securities of the Company representing 10% or more of the
combined voting power of the Company's then outstanding Voting Securities
increases his beneficial ownership of such securities by 5% or more over the
percentage so owned by such person, or (B) becomes the "beneficial owner" (as
defined in Rule 13d-3 under said Act), directly or indirectly, of securities of

nomination for election was previously so approved cease for any reason to
constitute a majority thereof, or (iii) the stockholders of the Company approve
a merger or consolidation of the Company with any other corporation other than a

surviving entity) at least 80% of the total voting power represented by the
Voting Securities of the Company or such surviving entity outstanding
immediately after such merger or consolidation, or the stockholders of the
Company approve a plan of complete liquidation of the

mean an attorney or firm of attorneys, selected in accordance with the
provisions of Section 1(c) hereof, who shall not have otherwise performed
services for the Company or Indemnitee within the last three years (other than
with respect to matters concerning the rights of Indemnitee under this
Agreement, or of other indemnitees under similar indemnity agreements).

          (e)  For purposes of this Agreement, a "Reviewing Party" shall mean
any appropriate person or body consisting of a member or members of the

          (f)  For purposes of this Agreement, "Voting Securities" shall mean

     11.  Counterparts.  This Agreement may be executed in one or more
          ------------                                                
counterparts, each of which shall constitute an original.

     12.  Binding Effect; Successors and Assigns.  This Agreement shall be
          --------------------------------------                          
binding upon and inure to the benefit of and be enforceable by the parties
hereto and their respective successors (including any direct or indirect
successor by purchase, merger, consolidation, or otherwise to all or
substantially all of the business and/or assets of the Company), assigns,
spouses, heirs, and personal and legal representatives.  The Company shall
require and cause any successor (whether direct or indirect by purchase, merger,
consolidation, or otherwise) to all, substantially all, or a substantial part of
the business and/or assets of the Company, by written agreement in form and
substance satisfactory to Indemnitee, expressly to assume and agree to perform
this Agreement in the same manner and to the same extent that the Company would
be required to perform if no such succession had taken place.  This Agreement
shall continue in effect regardless of whether Indemnitee continues to serve as
a director, officer, employee, agent, or fiduciary of the Company or of any
other enterprise at the Company's request.


     13.  Attorney's Fees.  In the event that any action is instituted by
          ---------------                                                
Indemnitee under this Agreement or under any liability insurance policies
maintained by the Company to enforce or interpret any of the terms hereof or
thereof, Indemnitee shall be entitled to be paid all Expenses incurred by
Indemnitee with respect to such action, regardless of whether Indemnitee is
ultimately successful in such action, and shall be entitled to the advancement
of Expenses with respect to such action, unless, as a part of such action, a
court of competent jurisdiction over such action determines that each of the
material assertions made by Indemnitee as a basis for such action was not made
in good faith or was frivolous.  In the event of an action instituted by or in
the name of the Company under this Agreement to enforce or interpret any of the
terms of this Agreement, Indemnitee shall be entitled to be paid all Expenses
incurred by Indemnitee in 
<PAGE>
 
defense of such action (including costs and expenses incurred with respect to
Indemnitee's counterclaims and cross-claims made in such action) and shall be
entitled to the advancement of Expenses with respect to such action, unless, as
a part of such action, a court having jurisdiction over such action determines
that each of Indemnitee's material defenses to such action was made in bad faith
or was frivolous.

     14.  Notice.  All notices and other communications required or permitted
          ------                                                             
hereunder shall be in writing, shall be effective when given, and shall in any
event be deemed to be given (a) five days after deposit with the U.S. Postal
Service or other applicable postal service, if delivered by first class mail
postage prepaid, (b) upon delivery, if delivered by hand, (c) one business day
after the business day of deposit with Federal Express or similar overnight
courier, freight prepaid, or (d) one day after the business day of delivery by
facsimile transmission, if delivered by facsimile transmission, with a copy by

the Indemnitee's address as set forth beneath his signature to this Agreement
and if to the Company at the address of its principal corporate offices
(attention: Secretary) or at such other address as such party may designate by
ten days' advance written notice to the other party hereto.

     15.  Consent to Jurisdiction.  The Company and Indemnitee each hereby
          -----------------------                                         
irrevocably consent to the jurisdiction of the courts of the State of Delaware
for all purposes in connection with any action or proceeding which arises out of
or relates to this Agreement and agree that any action instituted under this
Agreement shall be commenced, prosecuted, and continued only in the Court of
Chancery of the State of Delaware in and for New Castle County, which shall be
the exclusive and only proper forum adjudicating such a claim.

     16.  Severability.  The provisions of this Agreement shall be severable in
          ------------                                                         
the event that any of the provisions hereof (including any provision within a
single section, paragraph, or sentence) are held by a court of competent
jurisdiction to be invalid, void, or otherwise unenforceable, and the remaining
provisions shall remain enforceable to the fullest extent permitted by law.
Furthermore, to the fullest extent possible, the provisions of this Agreement
(including, without limitations, each portion of this Agreement containing any
provision held to be invalid, void, or otherwise unenforceable that is not
itself invalid, void, or unenforceable) shall be construed so as to give effect
to the intent manifested by the provision held invalid, illegal, or
unenforceable.

     17.  Choice of Law.  This Agreement shall be governed by and its provisions
          -------------                                                         
construed and enforced in accordance with the laws of the State of Delaware, as
applied to contracts between Delaware residents, entered into and to be
performed entirely within the State of Delaware, without regard to the conflict
of laws principles thereof.

     18.  Subrogation.  In the event of payment under this Agreement, the
          -----------                                                    
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of Indemnitee, who shall execute all documents required and shall do
all acts that may be necessary to secure such rights and to enable the Company
effectively to bring suit to enforce such rights.
<PAGE>
 
     19.  Amendment and Termination.  No amendment, modification, termination,
          -------------------------                                           
or cancellation of this Agreement shall be effective unless it is in writing
signed by both the parties hereto.  No waiver of any of the provisions of this
Agreement shall be deemed or shall constitute a waiver of any other provisions
hereof (whether or not similar) nor shall such waiver constitute a continuing
waiver.

     20.  Integration and Entire Agreement.  This Agreement sets forth the
          --------------------------------                                
entire understanding between the parties hereto and supersedes and merges all
previous written and oral negotiations, commitments, understandings, and
agreements relating to the subject matter hereof between the parties hereto.

     21.  No Construction as Employment Agreement.  Nothing contained in this
          ---------------------------------------                            
Agreement shall be construed as giving Indemnitee any right to be retained in
the employ of the Company or any of its subsidiaries or to serve on the Board of
Directors of the Company or any of its subsidiaries or to hold any other
position as a representative or designee of the Company or any of its
subsidiaries.

    SAFE HARBOR FOR FORWARD-LOOKING STATEMENTS UNDER THE PRIVATE SECURITIES
                         LITIGATION REFORM ACT OF 1995
 
                       CERTAIN CAUTIONARY STATEMENTS AND
                                 RISK FACTORS



     CSG Systems International, Inc. and its subsidiaries (collectively, the
Company) or their representatives from time to time may make or may have made
certain forward-looking statements, whether orally or in writing, including
without limitation, any such statements made or to be made in the Management's
Discussion and Analysis of Financial Condition and Results of Operations
contained in its various SEC filings or orally in conferences or
teleconferences. The Company wishes to ensure that such statements are
accompanied by meaningful cautionary statements, so as to ensure to the fullest
extent possible the protections of the safe harbor established in the Private
Securities Litigation Reform Act of 1995.

     ACCORDINGLY, THE FORWARD-LOOKING STATEMENTS ARE QUALIFIED IN THEIR ENTIRETY
BY REFERENCE TO AND ARE ACCOMPANIED BY THE FOLLOWING MEANINGFUL CAUTIONARY
STATEMENTS IDENTIFYING CERTAIN IMPORTANT FACTORS THAT COULD CAUSE ACTUAL RESULTS
TO DIFFER MATERIALLY FROM THOSE IN SUCH FORWARD-LOOKING STATEMENTS.

     This list of factors is likely not exhaustive. The Company operates in a
rapidly changing and evolving business involving the converging communications
markets, and new risk factors will likely emerge. Management cannot predict all
of the important risk factors, nor can it assess the impact, if any, of such
risk factors on the Company's business or the extent to which any factor, or
combination of factors, may cause actual results to differ materially from those
in any forward-looking statements.

     ACCORDINGLY, THERE CAN BE NO ASSURANCE THAT FORWARD-LOOKING STATEMENTS WILL
BE ACCURATE INDICATORS OF FUTURE ACTUAL RESULTS, AND IT IS LIKELY THAT ACTUAL
RESULTS WILL DIFFER FROM RESULTS PROJECTED IN FORWARD-LOOKING STATEMENTS AND
THAT SUCH DIFFERENCES MAY BE MATERIAL.
<PAGE>
 
NET LOSSES
 
  The Company has recorded annual net losses since inception (October 17,
1994) through December 31, 1997. These net losses have resulted from several
factors, including: (i) amortization of intangible assets (acquired software,
client contracts and related intangibles, and noncompete agreements and
goodwill); (ii) charge for purchased research and development; (iii) charge
for impairment of software development costs; (iv) charge for impairment of
intangible assets; (v) interest expense; (vi) stock-based employee
compensation expense; (vii) extraordinary losses from early extinguishment of
debt; and (viii) discontinued operations. There can be no assurance that the
Company will achieve or sustain profitability in the future. 
 
RELIANCE ON CCS
 
  The Company derived approximately 77.3% and 76.7% of its total revenues from
its primary product, Communications Control System ("CCS"), and related
products and services in the years ended December 31, 1996 and 1997,
respectively. CCS and related products and services are expected to provide
the substantial majority of the Company's total revenues in the foreseeable
future. The Company's results will depend upon continued market acceptance of
CCS and related products and services, as well as the Company's ability to
continue to adapt and modify them to meet the changing needs of its clients.
Any reduction in demand for CCS would have a material adverse effect on the
financial condition and results of operations of the Company. 
 
DEPENDENCE ON MAJOR CLIENTS
 
  During the years ended December 31, 1996 and 1997, revenues from TCI
represented approximately 25.9% and 32.9% of total revenues, respectively, and
revenues from Time Warner represented approximately 22.9% and 20.1% of total
revenues, respectively. As a result of the TCI Contract, revenues derived from
TCI are expected to increase significantly as a percentage of revenue. Loss of
all or a significant part of the business of either TCI or Time Warner would
have a material adverse effect on the financial condition and results of
operations of the Company. 
 
REQUIREMENTS OF THE TCI CONTRACT
 
  The TCI Contract requires the conversion of a significant number of
additional TCI customers onto the Company's customer care and billing system.
The TCI Contract provides certain performance criteria and other obligations to
be met by the Company. The Company is subject to various remedies and penalties
if it fails to meet the performance criteria or other obligations. The Company
is also subject to an annual technical audit to determine whether the Company's
products and services include innovations in features and functions that have
become standard in the industry. If an audit determines the Company is not
providing such an innovation and it fails to do so within the schedule required
by the contract, then TCI would be released from its exclusivity obligation to
the extent necessary to obtain the innovation from a third party. To fulfill the
TCI Contract and to remain competitive, the Company believes it will be required
to develop new and advanced features to existing products and services, new
products and services, and new technologies, all of which will require
substantial research and development. TCI also would have the right to terminate
the TCI Contract in the event of certain defaults by the Company. The
termination of the TCI Contract or of any of TCI's commitments under the
contract would have a material adverse effect on the financial condition and
results of operations of the Company.
 
                                       2

<PAGE>
 
RENEWAL OF TIME WARNER CONTRACTS
 
  The Company provides services to Time Warner under multiple, separate
contracts with various Time Warner affiliates. These contracts are scheduled
to expire at various times. The failure of Time Warner to renew contracts
representing a significant part of its business with the Company would have a
material adverse effect on the financial condition and results of operations
of the Company.
 
CONVERSION TO THE COMPANY'S SYSTEMS
 
  The Company's ability to convert new client sites to its customer care and
billing systems on a timely and accurate basis is necessary to meet the
Company's contractual commitments and to achieve its business objectives.
Converting multiple sites under the schedules required by contracts or
business requirements is a difficult and complex process. One of the
difficulties in the conversion process is that competition for the necessary
qualified personnel is intense and the Company may not be successful in
attracting and retaining the personnel necessary to complete conversions on a
timely and accurate basis. The inability of the Company to perform the
conversion process timely and accurately would have a material adverse effect
on the results of operations of the Company.
 
DEPENDENCE ON CABLE TELEVISION INDUSTRY
 
  The Company's business is concentrated in the cable television industry,
making the Company susceptible to a downturn in that industry. During the
years ended December 31, 1996 and 1997, the Company derived 77% and 73%,
respectively, of its revenues from companies in the U.S. cable television
industry. A decrease in the number of customers served by the Company's
clients would result in lower revenues for the Company. In addition, cable
television providers are consolidating, decreasing the potential number of
buyers for the Company's products and services. Furthermore, there can be no
assurance that cable television providers will be successful in expanding into
other segments of the converging communications markets. There can be no
assurance that new entrants into the cable television market will become
clients of the Company.
 
NEW PRODUCTS AND RAPID TECHNOLOGICAL CHANGE
 
  The market for customer care and billing systems is characterized by rapid
changes in technology and is highly competitive with respect to the need for
timely product innovations and new product introductions. The Company believes
that its future success depends upon continued market acceptance of its
current products, including CCS and related products and services, and its
ability to enhance its current products and develop new products that address
the increasingly complex and evolving needs of its clients. In particular, the
Company believes that it must respond quickly to clients' needs for additional
functionality and distributed architecture for data processing. Substantial
research and development will be required to maintain the competitiveness of
the Company's products and services in the market. Development projects can be
lengthy and costly, and are subject to changing requirements, programming
difficulties, a shortage of qualified personnel, and unforeseen factors which
can result in delays. There can be no assurance of continued market acceptance
of the Company's current products or that the Company will be successful in
the timely development of product enhancements or new products that respond to
technological advances or changing client needs.
 
CONVERGING COMMUNICATIONS MARKETS
 
  The Company's growth strategy is based in large part on the continuing
convergence and growth of the cable television, DBS, telecommunications, and
on-line services markets. If these markets fail to converge, grow more slowly
than anticipated, or if providers in the converging markets do not accept the
Company's products and services, there could be a material adverse effect on
the Company's growth.
 
COMPETITION
 
  The market for the Company's products and services is highly competitive.
The Company directly competes with both independent providers of products and
services and in-house systems developed by existing and
 
                                       3

potential clients. Many of the Company's current and potential competitors
have significantly greater financial, marketing, technical, and other
competitive resources than the Company, and many already have significant
international operations. There can be no assurance that the Company will be
able to compete successfully with its existing competitors or with new
competitors. 
 
CLIENT FAILURE TO RENEW OR UTILIZE CONTRACTS
 
  Substantially all of the Company's revenues are derived from the sale of
services or products under contracts with its clients. The Company does not
have the option to extend unilaterally the contracts upon expiration of their
terms. Many of the Company's contracts do not require clients to make any
minimum purchases, and contracts are cancelable by clients under certain
conditions.
 
ATTRACTION AND RETENTION OF PERSONNEL
 
  The Company's future success depends in large part on the continued service
of its key management, sales, product development, and operational personnel.
The Company is particularly dependent on its executive officers. Only one of
those executive officers is party to an employment agreement with the Company,
and such agreement is terminable upon 30 days' notice.
 
  The Company believes that its future success also depends on its ability to
attract and retain highly skilled technical, managerial, and marketing
personnel, including, in particular, additional personnel in the areas of
research and development and technical support. Competition for qualified
personnel is intense, particularly in the areas of research and development
and technical support. The Company may not be successful in attracting and
retaining the personnel it requires.
 
VARIABILITY OF QUARTERLY RESULTS
 
  The Company's quarterly revenues and results, particularly relating to
software and professional services, may fluctuate depending on various
factors, including the timing of executed contracts and the delivery of
contracted services or products, the cancellation of the Company's services
and products by existing or new clients, the hiring of additional staff, new
product development and other expenses, and changes in sales commission
policies. No assurance can be given that results will not vary due to these
factors. Fluctuations in quarterly results may result in volatility in the
market price of the Company's Common Stock.
 
DEPENDENCE ON PROPRIETARY TECHNOLOGY
 
  The Company relies on a combination of trade secret and copyright laws,
nondisclosure agreements, and other contractual and technical measures to
protect its proprietary rights in its products. There can be no assurance that
these provisions will be adequate to protect its proprietary rights. Although
the Company believes that its intellectual property rights do not infringe
upon the proprietary rights of third parties, there can be no assurance that
third parties will not assert infringement claims against the Company or the
Company's clients. 
 
INTERNATIONAL OPERATIONS
 
  The Company's business strategy includes a commitment to the marketing of
its products and services internationally, and the Company has acquired and
established operations outside of the U.S. The Company is subject to certain
inherent risks associated with operating internationally. Risks include
product development to meet local requirements such as the conversion to EURO
currency, difficulties in staffing and management, reliance on independent
distributors or strategic alliance partners, fluctuations in foreign currency
exchange rates, compliance with foreign regulatory requirements, variability
of foreign economic conditions, changing restrictions imposed by U.S. export
laws, and competition from U.S.-based companies which have firmly established
significant international operations. There can be no assurance that the
Company will be able to manage successfully the risks related to selling its
products and services in international markets.

INTEGRATION OF ACQUISITIONS
 
  As part of its growth strategy, the Company seeks to acquire assets,
technology, and businesses which would provide the technology and technical
personnel to expedite the Company's product development efforts, provide
complementary products or services or provide access to new markets and
clients. Acquisitions involve a number of risks and difficulties, including
expansion into new geographic markets and business areas, the requirement to
understand local business practices, the diversion of management's attention
to the assimilation of acquired operations and personnel, potential adverse
short-term effects on the Company's operating results, and the amortization of
acquired intangible assets.
 
YEAR 2000
 
  The Company's business is dependent upon various computer software programs
and operating systems that utilize dates and process data beyond the year
2000. If the actions taken by the Company to mitigate its risks associated
with the year 2000 are inadequate, there could be a material adverse effect on
the financial condition and results of operations of the Company. 
 
RELATIONSHIP WITH FIRST DATA CORPORATION
 
  The Company has entered into a data processing services agreement with FDC.
The Company is dependent upon FDC to perform these services for the operation
of CCS. The inability of FDC to perform these services satisfactorily could
have a material adverse effect on the financial condition and results of
operations of the Company. The existing agreement is scheduled to expire in
December 2001.
