              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. GENERAL

The condensed consolidated financial statements at March 31, 1999, and for the
three months then ended are unaudited and reflect all adjustments (consisting
only of normal recurring adjustments) which are, in the opinion of management,
necessary for a fair presentation of the financial position and operating
results for the interim period. The condensed consolidated financial statements
should be read in conjunction with the consolidated financial statements and
notes thereto, together with management's discussion and analysis of financial
condition and results of operations, contained in the Company's Annual Report on
Form 10-K for the year ended December 31, 1998, filed with the Securities and
Exchange Commission (the Company's 1998 10-K). The results of operations for the
three months ended March 31, 1999, are not necessarily indicative of the results
for the entire year ending December 31, 1999.

2. STOCK SPLIT

On March 5, 1999, the Company completed a two-for-one stock split, effected as a
stock dividend, for stockholders of record on February 8, 1999. Share and per
share data for all periods presented herein have been adjusted to give effect to
the split.

3. NET INCOME PER COMMON SHARE

Basic net income per common share is computed by dividing income available to
common stockholders by the weighted average number of common shares outstanding
during the period. Diluted net income per common share is consistent with the
calculation of basic net income per common share while giving effect to dilutive
potential common shares outstanding during the period. For all periods
presented, dilutive potential common shares consisted entirely of stock options.

For the quarters ended March 31, 1999 and 1998, weighted average outstanding
stock options of 3,200 and 761,128, respectively, have been excluded from the
computation of diluted net income per common share because the exercise prices
of these options were greater than the average market price of the common shares
for the respective quarters.

For the quarters ended March 31, 1999 and 1998, the weighted average dilutive
potential common shares (calculated using the treasury stock method) from Common
Stock Warrants of 2,012,527 and 1,225,386, respectively, are excluded from the
diluted net income per common share calculation as the events necessary to allow
the exercise of the warrants had not been satisfied as of March 31, 1999 or
1998. The Company expects certain of these warrants to become exercisable during
1999. See additional discussion of the Common Stock Warrants in the Company's
1998 10-K.

5. RECLASSIFICATION OF PRIOR PERIOD AMOUNTS

Certain March 31, 1998 amounts have been reclassified to conform with the March
31, 1999 presentation.

6. ACCOUNTING PRONOUNCEMENTS ISSUED BUT NOT YET EFFECTIVE

In June 1998, SFAS No. 133, "Accounting for Derivative Instruments and for
Hedging Activities" (SFAS 133) was issued. The Statement establishes accounting
and reporting standards requiring every derivative instrument, as defined, to be
recorded in the balance sheet as either an asset or liability measured at its
fair value. The Statement requires that changes in the derivative's fair value
be recognized currently in earnings unless specific hedge accounting criteria
are met. The Company expects to adopt SFAS 133 no later than fiscal year 2000,
and does not expect the adoption of this Statement to have a significant effect
on the Company's consolidated financial statements.

Three Months Ended March 31, 1999 Compared to Three Months Ended March 31, 1998

Revenues. Total revenues for the three months ended March 31, 1999, increased
44.2% to $71.1 million, from $49.3 million for the three months ended March 31,
1998.

Revenues from processing and related services for the three months ended March
31, 1999, increased 48.0% to $59.0 million, from $39.8 million for the three
months ended March 31, 1998. Of the total increase in revenue, approximately 68%
resulted from an increase in the number of customers of the Company's clients
which were serviced by the Company and approximately 32% was due to increased
revenue per customer. Customers serviced as of March 31, 1999 and 1998,
respectively, were 30.5 million and 23.6 million, an increase of 29.4%. The
increase in the number of customers serviced was due to the conversion of
additional customers by new and existing clients to the Company's systems, and
internal customer growth experienced by existing clients. From January 1, 1999
through March 31, 1999, the Company converted and processed approximately 1.0
million additional customers on its systems. Total annualized domestic revenue
per customer account for the first three months of 1999 was $9.10, compared to
$8.13 for the same period in 1998, an increase of 11.9%. Revenue per customer
increased primarily due to a greater percentage of processing revenues in 1999
being generated under the Tele-Communications, Inc. (TCI) processing contract
(the TCI Contract), and to a lesser degree, increased usage of ancillary
services by clients and price increases included in client contracts.

Revenues from software and related product sales and professional consulting
services for the three months ended March 31, 1999, increased 27.9% to $12.1
million, from $9.5 million for the three months ended March 31, 1998. This
increase relates primarily to the continued penetration of sales of software and
services to the Company's existing client base, as well as sales to new clients.

Cost of Revenues. Direct costs as a percentage of related revenues were 39.5%
for the three months ended March 31, 1999, compared to 44.8% for the three
months ended March 31, 1998. The improvement between periods relates primarily
to better overall leveraging of processing costs as a result of the continued
growth of the customer base processed on the Company's system. Amortization of
client contracts for the three months ended March 31, 1999, increased 67.5% to
$1.8 million, from $1.1 million for the three months ended March 31, 1998. The
increase in expense is due primarily to an increase in amortization of the value
assigned to the TCI Contract. The value assigned to the TCI Contract is being
amortized over the life of the contract in proportion to the financial minimums
included in the contract.

Gross Margin. Gross margin for the three months ended March 31, 1999, increased
57.5% to $41.2 million, from $26.2 million for the three months ended March 31,
1998, due primarily to revenue growth. The gross margin percentage increased to
58.0% for the three months ended March 31, 1999, compared to 53.1% for the three
months ended March 31, 1998. The overall increase in the gross margin percentage
is due primarily to 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 (R&D) expense for the
three months ended March 31, 1999, increased 16.8% to $7.6 million, from $6.5
million for the three months ended March 31, 1998. As a percentage of total
revenues, R&D expense decreased to 10.7% for the three months ended March 31,
1999, from 13.2% for the three months ended March 31, 1998.

During the three months ended March 31, 1998, the Company capitalized third
party, contracted programming costs of approximately $0.6 million, related
primarily to enhancements to existing products. The Company did not capitalize
any software development costs during the three months ended March 31, 1999. As
a result, total R&D development expenditures (i.e., the total R&D costs
expensed, plus the capitalized development costs) for the three months ended
March 31, 1999 and 1998, were $7.6 million, or 10.7% of total revenues, and $7.1
million, or 14.4% of total revenues, respectively. The overall increase in the
R&D expenditures between periods is due primarily to increased efforts on
several products which are in development and


                                       9
<PAGE>
 
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 (S&M) expense for the three
months ended March 31, 1999, increased 36.5% to $3.3 million, from $2.4 million
for the three months ended March 31, 1998. As a percentage of total revenues,
S&M expense decreased to 4.6% for the three months ended March 31, 1999, from
4.9% for the three months ended March 31, 1998. The overall decrease in S&M
expenses as a percentage of total revenues is due primarily to increased
revenues, while controlling S&M costs.

General and Administrative Expense. General and administrative (G&A) expense for
the three months ended March 31, 1999, increased 12.1% to $6.3 million, from
$5.6 million for the three months ended March 31, 1998. As a percentage of total
revenues, G&A expense decreased to 8.8% for the three months ended March 31,
1999, from 11.4% for the three months ended March 31, 1998. The increase in G&A
expenses relates primarily to the continued expansion of the Company's
administrative staff and other administrative costs to support the Company's
overall growth. The decrease in G&A expenses as a percentage of total revenues
is due primarily to increased revenues, while controlling G&A costs.

Depreciation Expense. Depreciation expense for the three months ended March 31,
1999, increased 30.8% to $2.4 million, from $1.8 million for the three months
ended March 31, 1998. The increase in expense relates to capital expenditures
made during 1998 and the first three months of 1999 in support of the overall
growth of the Company, consisting principally of computer hardware and related
equipment and statement processing equipment and related facilities.
Depreciation expense for all property and equipment is reflected separately in
the aggregate and is not included in the other components of operating expenses.

Operating Income. Operating income for the three months ended March 31, 1999,
was $20.2 million or 28.5% of total revenues, compared to $8.4 million or 17.0%
of total revenues for the three months ended March 31, 1998. The increase
between years relates to the factors discussed above.

Interest Expense. Interest expense for the three months ended March 31, 1999,
decreased 12.6% to $2.2 million, from $2.5 million for the three months ended
March 31, 1998, with the decrease attributable primarily to scheduled principal
payments on the Company's long-term debt and a decrease in interest rates
between periods.

Income Tax Provision. As of December 31, 1997, the Company had recorded a
valuation allowance against certain deferred tax assets since realization of
future tax benefits was not sufficiently assured as of that date. During the
first quarter of 1998, the Company realized a portion of the deferred tax assets
such that the overall income tax provision for the quarter was zero. During the
fourth quarter of 1998, the Company concluded that it was more likely than not
that it would realize the entire tax benefit from its deferred tax assets and
eliminated the entire valuation allowance as of December 31, 1998.

For the three months ended March 31, 1999, the Company's recorded an income tax
provision of $7.0 million, or an effective income tax rate of approximately 38%,
which represents the Company's estimate of the effective book income tax rate
for 1999.

Adjusted Results of Operations
- ------------------------------
The Company incurred certain one-time or acquisition-related charges
(Acquisition Charges) in connection with the CSG Acquisition in November 1994.
The Acquisition Charges include amortization of acquired software, client
contracts and related intangibles, noncompete agreement, goodwill, and
stock-based compensation and totaled $2.0 million and $2.1 million for the
quarters ended March 31, 1999 and 1998, respectively. The Company's adjusted
results of operations excluding the impact of these items are 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%, and outstanding shares on a diluted basis. See the
Company's "Management's Discussion and Analysis of Financial Condition and

TCI Contract and AT&T Merger
- ----------------------------
During the three months ended March 31, 1999 and 1998, revenues from TCI and
affiliated companies generated under the TCI Contract represented approximately
44.2% and 39.1% of total revenues, respectively. The TCI Contract has a 15-year
term and expires in 2012. The TCI Contract has minimum financial commitments
over the term of the contract and includes exclusive rights to provide customer
care and billing products and services for TCI's offerings of wireline video,
all Internet/high-speed data services, residential wireline telephony services,
and print and mail services. The TCI Contract provides certain performance
criteria and other obligations to be met by the Company. The Company is required
to perform certain remedial efforts and is subject to certain 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 wireline video industry. To date, the Company believes it has
complied with the terms of the contract. Since execution of the TCI Contract in
September 1997 through March 31, 1999, the Company has successfully converted
approximately 8.6 million TCI cable television customers onto its system.
Approximately 1.7 million additional TCI cable television customers are
currently scheduled to be converted during the remainder of 1999.

AT&T completed its merger with TCI in March 1999. At this time, it is too early
to determine the near- and long-term impact, if any, the merger will have on the
Company's relationship with the combined entity. AT&T has announced its planned
efforts to provide convergent communications services in 10 United States cities
during 1999. The Company is participating in those convergent trials and is
working closely with AT&T to provide customer care and billing services to
customers in those cities. The Company expects to continue performing
successfully under the TCI Contract, and is hopeful that it can continue to sell
products and services to the combined entity that are in excess of the minimum
financial commitments included in the contract.

Liquidity and Capital Resources
- -------------------------------
As of March 31, 1999, the Company's principal sources of liquidity included cash
and cash equivalents of $40.0 million. The Company also has a revolving credit
facility in the amount of $40.0 million, of which there were no borrowings
outstanding. The Company's ability to borrow under the revolving credit facility
is subject to maintenance of certain levels of eligible receivables. At March
31, 1999, all of the $40.0 million revolving credit facility was available to
the Company. The revolving credit facility expires in September 2002.

As of March 31, 1999 and December 31, 1998, respectively, the Company had $58.5
million and $60.5 million in net trade accounts receivable, a decrease of $2.0
million. The Company's trade accounts receivable balance includes billings for
several non-revenue items, such as postage, communication lines, 


                                       11
<PAGE>
 
travel and entertainment reimbursements, sales tax, and deferred items. As a
result, the Company evaluates its performance in collecting its accounts
receivable through its calculation of days billings outstanding (DBO) rather
than a typical days sales outstanding (DSO) calculation. DBO is calculated based
on the billings for the period (including non-revenue items) divided by the
average net trade accounts receivable balance for the period. The Company's DBO
calculations for the three months ended March 31, 1999 and 1998 were 60 days and
58 days, respectively.

During the three months ended March 31, 1999, the Company generated $22.3
million of net cash flow from operating activities. Cash generated from these
sources and the proceeds of $2.3 million from the issuance of common stock
through the Company's stock incentive plans were used to (i) fund capital
expenditures of $2.3 million, (ii) pay conversion and other incentive payments
of $4.6 million, and (iii) repay long-term debt of $17.3 million, which includes
$2.3 million of scheduled payments and an optional prepayment of $15.0 million.

Earnings before interest, taxes, depreciation and amortization (EBITDA) for the
three months ended March 31, 1999 was $26.3 million or 36.9% of total revenues,
compared to $12.9 million or 26.1% of total revenues for the three months ended
March 31, 1998. EBITDA is presented here as a measure of the Company's debt
service ability and is not intended to represent cash flows for the periods.

Interest rates for 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 spread, with the spread dependent upon the Company's leverage ratio.
Effective April 1, 1999, the spread on the LIBOR rate and the prime rate will be
0.50% and 0%, respectively.

The Company is required to make certain conversion incentive payments under the
TCI Contract, with the amounts and the timing of the payments based principally
upon the number of TCI customers converted to, and the total number of TCI
customers processed on, the Company's customer care and billing system. Total
payments as of March 31, 1999 have been approximately $7.1 million. Based on the
conversions performed to date and the future conversions scheduled as of March
31, 1999, the Company expects to pay the remaining $18.9 million to TCI in 1999.

The Company continues to make significant investments in capital equipment,
facilities, and research and development. The Company had no significant capital
commitments as of March 31, 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, income taxes, debt service,
conversion incentive payments and capital expenditures for both its short and
long-term purposes.

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. The
Company's actions to address the risks associated with the year 2000 are as
follows:

The Company's State of Readiness. The Company has established a corporate
program to coordinate its year 2000 (Y2K) compliance efforts across all business
functions and geographic areas. The scope of the program includes addressing the
risks associated with the Company's (i) information technology (IT) systems
(including the Company's products and services), (ii) non-IT systems that
include embedded technology, and (iii) significant vendors and their Y2K
readiness. The Company is utilizing the following steps in executing its Y2K
compliance program: (1) awareness, (2) assessment, (3) renovation (including
upgrades and enhancements to the Company's products), (4) validation and
testing, and (5) implementation. The Company has completed the awareness and
assessment steps for all areas.


                                       12
<PAGE>
 
Products and Services. The renovation step has been substantially completed for
- ---------------------
all significant products and services, and the Company now is focusing its
efforts on validation and testing. The Company's most significant renovation
effort involved its core product, Communications Control System (CCS). CCS
utilizes one subroutine for calculating dates, with the various computer
programs within CCS with date dependent calculations accessing this subroutine.
As a result, all date calculations are performed in one location. The renovation
of this subroutine and the related interfaces to the various date dependent
programs has been completed. The Company has completed the testing of the CCS
application using its standard testing methodologies, while adding date
simulation to specifically address the Y2K risk. Such date simulation considered
pre-2000, cross over, and post-2000 time frames, including year 2000 leap year
considerations. The renovated and tested version of CCS has been implemented
into the production environment.

The Company expects to be substantially completed with its testing of third
party interfaces (e.g., addressable devices) to CCS by the end of the second
quarter of 1999. The Company is dependent upon the third parties for such
testing, and expects to be completed with the testing by the end of the third
quarter of 1999. The interfaces are not complex and are considered low risk by
the Company.

For the Company's software products, no significant renovation is believed
necessary, as the products are relatively new and were designed to be Y2K
compliant. The Company is testing these products with similar date simulation
techniques discussed above to ensure they are Y2K compliant. Such testing is
substantially completed, with the remaining testing expected to be done by the
end of the second quarter of 1999.

The Company has developed a process to manage further updates or enhancements to
any product related software code which has been tested and internally certified
as Y2K compliant, and is considering a plan to "freeze" all changes to mission
critical product related software after November 1999. The Company also plans to
retest CCS (through an initial program load of the CCS system) in the fourth
quarter of 1999 to ensure continued Y2K compliance. Several CSG clients are
conducting tests of the Company's products in conjunction with their own
operating environments. Several test phases have been completed (beginning in
December 1998), with additional phases continuing into the third quarter of
1999, including participation by TCI in such testing.

Internal Systems. Renovation and/or testing of the Company's significant
- ----------------
internal use IT Systems (e.g., payroll systems, accounting systems, etc.) is
substantially complete, with all systems expected to be tested and implemented
by the end of the second quarter of 1999. The Company has a substantial number
of non-IT systems that include embedded technology (e.g., buildings, plant,
equipment and other infrastructure) that are owned and managed by the lessors of
the buildings in which the Company is located. The Company has sent letters to
its lessors requesting certifications of the Y2K compliance of the embedded
systems. The Company has received some of the certifications from lessors and
expects to receive the remaining certifications by the end of the second quarter
of 1999. Letters have also been sent to third parties providing other internal
non-IT systems with embedded technology (e.g., statement insertion machines,
copy machines, etc.). Some of the Y2K certifications and/or upgrades are
complete, with all systems expected to be completed by the end of the second
quarter of 1999.

Significant Vendors. As part of the Company's Y2K compliance program, the
- -------------------
Company has contacted its significant vendors to assess their Y2K readiness. For
substantially all mission critical third party software embedded in or specified
for use in conjunction with the Company's IT systems and products, the Company's
communications with the vendors indicates that the vendors believe they are
fully Y2K compliant. The remaining vendors indicate that they are substantially
Y2K compliant. The Company expects to receive further enhancements from these
vendors as they become available throughout 1999 to bring the products into full
Y2K compliance. Such third party software has been or is being tested in
conjunction with the testing of the IT systems and products discussed above. All
other significant vendors (including the Company's vendor who provides data
processing services for CCS) have indicated they are substantially Y2K
compliant. There can be no assurance that (i) the 


                                       13
<PAGE>
 
Company's significant vendors will succeed in their Y2K compliance efforts, or
(ii) the failure of vendors to address Y2K compliance will not have a material
adverse effect on the Company's business or results of operations.

The Costs to Address the Company's Year 2000 Issues. Since inception of its
program in 1995 through March 31, 1999, the Company has incurred and expensed
costs of approximately $3.2 million related to Y2K compliance efforts. The total
estimated costs to complete the Company's Y2K compliance effort are
approximately $0.7 million. The estimated costs to complete, which does not
include any costs which may be incurred by the Company if its significant
vendors fail to timely address Y2K compliance, is based on currently known
circumstances and various assumptions regarding future events. However, there
can be no assurance that these estimates will be achieved and actual results
could differ materially from those anticipated.

The Risks of the Company's Year 2000 Issues. The Company's failure to timely
resolve the Y2K risks could result in system failures, the generation of
erroneous information, and other significant disruptions of business activities,
including among others, access to CCS and the use of related software products,
and timely printing and delivery of clients' customers' statements. Although the
Company believes it will be successful in its Y2K compliance efforts, there can
be no assurance that the Company's systems and products contain all necessary
date code changes. In addition, the Company's operations may be at risk if its
vendors and other third parties (including public and private infrastructure
services, such as electricity, water, gas, transportation, and communications)
fail to adequately address the Y2K issue or if software conversions result in
system incompatibilities with these third parties. To the extent that either the
Company or a third party vendor or service provider on which the Company relies
does not achieve Y2K compliance, the Company's results of operations could be
materially adversely affected. Furthermore, it has been widely reported that a
significant amount of litigation surrounding business interruption will arise
out of Y2K issues. It is uncertain whether, or to what extent, the Company may
be affected by such litigation.

As is the case with many software companies and service providers, if the
Company's current or future clients experience significant business
interruptions due to their failure to achieve Y2K compliance, the Company's
results of operations could be materially adversely affected. There can be no
assurance that the Company's current or future clients will adequately and
successfully address their Y2K risk and not experience any business
interruptions.

The Company's Contingency Plan. The Company is addressing the need for any Y2K
specific contingency plan as part of its overall business continuity planning,
with modifications to the plan where Y2K specific exposures are identified as
the Company continues to execute its Y2K compliance project during 1999. The
Company is establishing a Y2K task force for all mission critical operations of
the Company which will provide dedicated personnel to escalate the resolution of
any Y2K specific matters that may occur. The Company has implemented a
restricted vacation policy for December 1999 and January 2000 to ensure all
mission critical personnel are available if any Y2K specific matters occur.

The (i) inability to timely implement a contingency plan, if deemed necessary,
and (ii) the cost to develop and implement such a plan, may have a material
adverse effect on the Company's results of operations.

Certain Factors That May Affect Future Results of Operations. Except for
statements of existing or historical facts, the foregoing discussion of Y2K
consists of forward-looking statements and assumptions relating to forward-
looking statements, including without limitation the statements relating to
future costs, the timetable for completion of Y2K compliance efforts, potential
problems relating to Y2K, the Company's state of readiness, third party
representations, and the Company's plans and objectives for addressing Y2K
problems. Certain factors could cause actual results to differ materially from
the Company's expectations, including without limitation (i) the failure of
vendors and service providers to timely achieve Y2K compliance, (ii) system
incompatibilities with third parties resulting from

                                       14
<PAGE>
 
software conversions, (iii) the Company's systems and products not containing
all necessary date code changes, (iv) the failure of existing or future clients
to achieve Y2K compliance, (v) potential litigation arising out of Y2K issues,
the risk of which may be greater for information technology based service
providers such as the Company, (vi) the failure of the Company's validation and
testing phase to detect operational problems internal to the Company, in the
Company's products or services or in the Company's interface with service
providers, vendors or clients, whether such failure results from the technical
inadequacy of the Company's validation and testing efforts, the technological
infeasibility of testing certain non-IT systems, the perceived cost-benefit
constraints against conducting all available testing, or the unavailability of
third parties to participate in testing, or (vii) the failure to timely
implement a contingency plan to the extent Y2K compliance is not achieved.

                        RESTATED AND AMENDED CSG MASTER
                    SUBSCRIBER MANAGEMENT SYSTEM AGREEMENT
                                    BETWEEN
                               CSG SYSTEMS, INC.
                                      AND
                       TCI CABLE MANAGEMENT CORPORATION

This Fourth Amendment (the "Amendment") is executed this 31st day of March,
1999, and is made by and between CSG Systems, Inc., a Delaware corporation
("CSG") and TCI Cable Management Corporation ("Customer"). CSG and Customer
entered into a certain Restated and Amended CSG Master Subscriber Management
System Agreement dated August 10, 1997, which has subsequently been amended
pursuant to separately executed amendments (collectively, the "Agreement"), and
now desire to amend the Agreement in accordance with the terms and conditions
set forth in this Amendment. If the terms and conditions set forth in this
Amendment shall be in conflict with the Agreement, the terms and conditions of
this Amendment shall control. Any terms in initial capital letters or all
capital letters used as a defined term but not defined in this Amendment, shall
have the meaning set forth in the Agreement. Upon execution of this Amendment by
the parties, any subsequent reference to the Agreement between the parties shall
mean the Agreement as amended by this Amendment. Except as amended by this
Amendment, the terms and conditions set forth in the Agreement shall continue in
full force and effect according to their terms

CSG and Customer agree as follows:

1. Section 7 of the Agreement shall be modified to include the following as
Section 7(h):

CSG represents and warrants that all components of any systems/products and/or
services purchased by Customer to perform the activities authorized or
contemplated by the Agreement or by any schedules or exhibits thereto, are
designed to be used prior to, during and after the calendar year 2000 A.D., and
that the systems/product will operate during each such time period without error
or interruption relating to date data, including without limitation, any error
or interruption relating to, or the product of, date data which represents or
references different centuries or more than one century, or leap year, in any
level of any systems/product hardware or software, including, without
limitation, microcode, firmware, application programs, user interfaces, files
and databases (such representation and warranty being referred to as "Year 2000
Compliant"). If CSG is unable or unwilling to correct the system/product/service
within a reasonable period of time after receiving written notice from Customer
specifying the nature of the failure, then Customer shall have the right to seek
all other available remedies, subject to the limitations contained in this
Agreement.

2. Attachment 3 which sets forth the Performance Standards is hereby deleted and
replaced with Attachment 3 attached hereto.

3. Section 9(b) of Schedule A is deleted in its entirety and replaced with the
following:

      (i) CSG will make available to Customer 3.1 Full Time Equivalent employees
      ("Technical FTEs") per increment of one million (1,000,000) of Customer's
      subscribers being processed by the CCS Services, up to a maximum of forty
      (40) Technical FTEs. Pursuant to the terms of this Section 9(b), the
      Technical FTEs will provide the following services related to the
      maintenance and development of the CCS Services received by Customer,
      pursuant to priorities determined by Customer:

      (A) database maintenance programming (i.e., update re-zips, recreating
      reports, performing statement reruns, cycle changes, file stripes, cycle
      freezes, code table adds, changes and deletes, refund check reruns, adding

                                              and the Redacted Material has been
                                           separately filed with the Commission"

      systems/prins/agents, all CSG telecommunication access fee adds, changes
      or deletes, respools, forms change and UDF Mirrors); 
      (B) product enhancement that will most likely be used by other CSG
      customers in the cable operator industry; and
      (C) product enhancement that is Customer specific.

      The fees for services rendered by the Technical FTEs are set forth in
      Schedule D. However, Customer (***) for any fees associated with any
      services described in subsection (A) above that fall within the allotment
      set forth in Subsection (i) above. Any such services in excess of that
      allotment shall be billable in accordance with the fees set forth in
      1.II.W of Schedule D. Customer shall (***) be responsible for (***)
      percent (***%) of the product development fees set forth in 1.II.W of
      Schedule D associated with the rendering of any services that are
      described in subsection (B) above that fall within the allotment set forth
      in subsection (i) above. Subject to the terms of the Master Agreement, any
      such services in excess of that allotment shall be billable in accordance
      with the fees set forth in 1.II.W of Schedule D. Customer shall be
      responsible for (***) percent (***%) of the fees set forth in Schedule D
      associated with the rendering of any services that are described in
      subsection (C) above. Notwithstanding anything to the contrary, the
      foregoing relates to fees to be charged to Customer to cover CSG's
      development costs, not operational costs. If any Statements of Work
      relating to any services described in this Section 9(b) involve additional
      operating expenses to CSG, Customer will be responsible for any such costs
      in accordance with the terms of the Master Agreement and any applicable
      Statements of Work.

      (ii) CSG's Product Management group and Customer's Subscriber Billing
      Group shall review all requests for services under this Section 9(b), and
      if they reasonably determine that any such services constitute
      enhancements that could be implemented into CSG's CCS Products as part of
      CSG's regular development activities, CSG will not bill Customer for such
      services. If this is not the case, however, Customer shall pay for such
      services in accordance with the preceding paragraph. CSG and Customer
      agree to form a committee to resolve any disagreements regarding the
      classification of services hereunder and/or any dispute regarding the
      classification of services under Subsection (iii) below. If necessary,
      this committee shall meet monthly (as part of the CSG/TCI Monthly
      Operations Review).

      (iii) CSG and Customer shall mutually agree upon the category of services
      requested by Customer prior to the rendering of any services by CSG.
      Notwithstanding anything contained in this Section 9(b), Customer shall,
      at no additional cost, be entitled, on an annual basis, to three thousand
      (3,000) hours of service by the Technical FTEs in connection with services
      for which CSG and Customer cannot agree upon one of the three categories
      described in subsection (i) above.

      (iv) Any technical services requested by Customer during any given month
      in excess of those provided by the Technical FTEs pursuant to the first
      sentence of subsection (i) above may be provided by CSG at the fees set
      forth in Schedule D. CSG will provide Customer with a monthly report that
      describes all activities undertaken by the Technical FTEs during such
      month.

      (v) CSG and Customer will, on an annual basis, review the procedures set
      forth in this Section 9(b) to determine whether modifications are
      necessary to achieve greater efficiency.

      (vi) If Customer requests that any Completion Date set forth in a
      Statement of Work be made sooner, CSG shall investigate the feasibility of
      such request and shall inform Customer of its determination. If CSG
      notifies Customer that performance under the Statement of Work can be
      expedited, and if there are any additional costs associated with any such
      modification, CSG shall so notify Customer of the extent of the additional
      costs and Customer shall be responsible for any such additional costs. If
      CSG notifies Customer that performance cannot be expedited, CSG shall
      provide Customer with its business reasons for its determination.

4. The Conversion/Implementation Services for CCS are set forth on Exhibit A-2
attached hereto.

5. Exhibit C-3 which sets forth the installation and support services for the
CCS Products (excluding Vantage) currently states that the installation and
support services ACSR are to be completed. Exhibit C-3 is hereby amended to

      prior approval, which may be subject to additional charges.

      *CSG Vantage usage information (CPU Minutes) is tracked within CSG's
      Vantage processing environment through the use of a tool that provides
      systems management, chargeback, and resource accounting functions. Usage
      is tracked for the CPU time it takes the query to run and process against
      the Relational Database Management System (RDBMS). Vantage usage is not
      collected for network transmission time, elapsed time associated with wait
      in a shared resource environment, and elapsed time while developing a
      request(s). Vantage usage information is tracked in CPU Seconds.

      Charges for additional Vantage CPU Usage will be calculated for the total
      TCI entity using the total of allocated CPU minutes for those System Sites
      being charged for Basic Vantage Reporting compared to the actual CPU Usage
      of the total TCI entity.

      **This fee is for the deletion of an existing Vantage site (sys/prin) or
      the movement of an existing Vantage site (sys/prin) from one Division or
      Joint Venture structure to an alternate existing Division or Joint Venture
      structure within the currently defined TCI Vantage database schema.

Mailing Services Specifications and Packaging of Inserts
- --------------------------------------------------------
The client can supply the inserts or CSG can produce them for the client.
Printing of inserts by CSG allows fast, reliable delivery, permits shorter
lead-times, and ensures that all of the design and production specifications
described below will be met. CSG requires that a 5% overage be added to the
volume of inserts you order to allow for any damages. The inserts must be
delivered 7 business days prior to the start date. Failure to meet this
lead-time will result in a $(***) late fee and will delay the insertion of those
pieces. Additional fees are applicable if LOAs and/or inserts arrive after print
cycle which would requires statement and postal report reruns. CSG will destroy
inserts within 60 days of receipt unless disposition says to return. Inserts
should not be shipped prior to 30 days before first cycle used. No insert will
be stored for longer than 90 days at the CSG warehouse.

Specifications for inserts
- --------------------------
1) Size
   ----
If the size of your statement is 7 x 11:
      a) Maximum size of a finished insert = 7 x 3 1/2 inches 
      b) Minimum size of a finished insert = 5 1/2 x 3 inches
If the size of your statement is 8 1/2 x 11:
      a) Maximum size of a finished insert = 8 3/4 x 3 3/4 inches
      b) Minimum size of a finished insert = 5 1/2 x 3 inches
2) Paper specifications
   --------------------
      a) Paper stock minimum weights are:
            50 lbs. minimum - uncoated and unfolded
            50 lbs. minimum - coated and folded
            *60 lbs. offset paper is considered standard.
      b) Anything under 50 lbs. stock or hard finished paper cannot be inserted.
      (Example: varnish)
      c) Maximum weight is postcard stock.
3) Fold
   ----
      a) Single folds are acceptable.
      b) Unacceptable are two-fold that are accordion folds, end folds, or `Z'
      folds.
      c) Folds must have sharp creases which maintain the accuracy of the fold
      throughout the print run. Below are graphics that show acceptable and not
      acceptable insert fold for machine insertion.
      d) Folded inserts must face the same direction in each bundle. Do not
      crisscross inserts within bundles, as this will result in a rebanding
      charge. Special are should be taken during folding and packaging to
      prevent the inserts from nesting one inside the other.

Acceptable folds for machine insertion

      Accordion fold is not acceptable            End fold is not acceptable

CSG does not insert pieces with staples, plastic, metal, magnets or other
foreign materials as these jam and can damage the machines. If you are not
certain an insert will meet CSG's specifications please contact your Insert
Control Representative.

4) Identification of inserts
   -------------------------
      a) Inserts that are similar in appearance must have the Client ID # or
      Business Unit # printed on the insert itself. This needs to be placed on
      the outside of the insert that readily identifies one version from
      another. The advantage of having the insert number on each insert and in a
      consistent location is to aid in identifying the inserts as they are
      received at the warehouse. It also provides each department that handles
      the inserts an instant visual as they verify, prepare and insert the
      statement order. 
      b) Large orders of look-a-like inserts, either generic or customized,
      should be preceded by a manifest which lists quantity, Client ID # or
      Business Unit #. This will assure the proper distribution of the inserts.
      c) Quantity - please note that the printing industry standard is plus or
      minus 10% so make adjustments accordingly. CSG requests an additional 5%
      over the amount needed for machine damages during insertion.

Packaging of the inserts
- ------------------------
1) Banding
   -------
      a) Banding is required for all inserts. They are to be banded into 3-4
      inch bundles the quantity per bundle must be divisible by 50; the quantity
      per bundle must be consistent in each bundle.
      b) Paper banding is preferred over other types. Paper bands must be of
      heavy stock and no less than 3 inches wide and securely fastened. 
      c) Rubber band should be size #64 (3 1/2x1/32x1/4)
            * Single sheet inserts should be banded with a single rubber band
            placed in the center of the bundle. Ensure that the bands are not
            too tight, which could cause warping; or too weak which could snap
            during shipment
            * Multi-page folded inserts should be banded with a rubber band
            placed on each end. This prevents warping of material and allows a
            better flow during insertion with less damages.
      d) The fold of the inserts must face the same direction in a bundle. 
      e) Shrink wrapping is permissible. Ionization of shrink wrapped bundles is
      preferred.

All unbanded material for insertion into cycle billing orders will be banded at
a cost to the client of $5.00 per 1,000.

2) Packing and Shipping
   --------------------
      a) Boxes need to be packaged so that contents do not shift, move or
      otherwise be subject to damage during shipment. Delays occur in the
      processing of inserts when a package is received with contents damaged.
      Inserts damaged excessively during shipping will be refused.
      b) All material should be shipped in securely taped, strong cartons (200
      lb. test cardboard) with reinforced sides to prevent the material from
      becoming curled, bent at the corners or mutilated during shipment. 
      c) Total box weight cannot exceed 50 lbs. Inserts should be securely
      packed within the cartons.
      d) Only one version or type of insert per box.
      e) A shipping document must accompany each shipment, again listing
      customer name, customer/system #, number of cartons, and quantity per box.
      f) CSG will refuse any C.O.D. shipment.
      g) All inserts shipped to CSG will be inspected to ensure that
      specifications are adhered to. Insert shipments that do not adhere to
      specifications or have quantities that are in question may not be
      accepted. CSG Systems the right to refuse inserts that do not meet our
      specifications or are damaged during shipment.
      h) All material must be delivered on wooden pallets of 36" x 48" in
      dimension. (DO NOT double stack pallets)

                         CSG.web(TM) SOFTWARE LICENSE

This Schedule L is made as of this 31st day of March, 1999, between CSG Systems,
Inc. ("CSG") and TCI Cable Management Corporation ("Customer"), pursuant to the
Restated and Amended Master Subscriber Management System Agreement executed as
of August 10, 1997, and of which this Schedule L forms an integral part.

1. License and Facilities Management Services. CSG hereby grants Customer, and
Customer hereby accepts from CSG, a non-exclusive and non-transferable right to
use CSG.web software product described in Section 2 below ("CSG.web") and in the
designated environment described in Section 3 below (the "Designated
Environment"), for the fees set forth in Schedule D and subject to the terms and
                                         ----------
conditions specified below and in the Master Agreement. Also for the fees set
forth in Schedule D, Customer shall purchase the Facilities Management Services
         ----------

2. CSG.web. "CSG.web" means (i) the machine-readable object code version of the

L-1, whether embedded on disc, tape or other media (the "Software"), which will
be located at CSG's premises unless CSG and Customer execute an amendment to
this Agreement that expressly provides otherwise; (ii) the published user
manuals and documentation that CSG makes generally available for the Software
(the "Documentation"), (iii) the fixes, updates, upgrades or new versions of the
Software or Documentation that CSG may provide to Customer under this Schedule L
                                                                      ----------
(the "Enhancements") and (iv) any customization or addition to the Software,
Documentation or Enhancements that CSG may provide pursuant to Schedule B
                                                               ----------
executed concurrently with this Schedule L (the "Customization"). Nothing in
                                ----------

other computer programs and hardware equipment CSG specifies for use with the
System as set forth in Exhibit L-1, or otherwise approved by CSG in writing for
Customer's use with CSG.web. Customer may use CSG.web only in the Designated
Environment and will be solely responsible for upgrading the Designated

Customer fails to do so, CSG will have no obligation to continue maintaining and
supporting CSG.web. CSG shall certify the Designated Environment prior to the
commencement of CSG's obligations under this Schedule L. Unless CSG has
                                             ----------
certified the Designated Environment, CSG shall have no obligation to perform
under this Schedule L, including no obligation to maintain and support CSG.web.
           ----------
Any other use of CSG.web will require CSG's prior approval, and may be subject
to additional charges. If Customer uses CSG.web via the Facilities Management
Services described in Exhibit L-1 and as a result CSG does not provide Customer
with any Software, the foregoing provisions regarding the Designated Environment
will not be applicable.

4. Use. If, at any time during the term of this Schedule L (and as reflected by
                                                ----------
an executed amendment hereto), CSG.web is used by Customer other than pursuant

CSG and Customer will establish the terms, conditions and charges under which
CSG provides any such customization services in a Statement Of Work incorporated
into Schedule B. In no event will any such customization services affect
     ----------
Customer's acceptance of CSG.web pursuant to this Schedule L.

    ----------
version of CSG.web that CSG and its licensors decide, in their sole discretion,
to make generally available as a separately priced item. This Section will not
be interpreted to require CSG to (i) develop and release Updates or Enhancements
or (ii) customize the Updates or Enhancements to satisfy Customers' particular
requests. If an Update or Enhancement replaces the prior version of the System,
Customer will promptly install the Update or Enhancement and destroy such prior
version upon installing the Update or Enhancement. CSG will have no obligation
to maintain and support CSG.web if Customer has modified CSG.web. At Customer's

    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.

RELIANCE ON CCS
- ---------------
The Company derived approximately 78% and 77% of its total revenues from its
primary product, Communications Control System (CCS), and related products and
services in the years ended December 31, 1998 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.

REQUIREMENTS OF THE TCI CONTRACT
- --------------------------------
The TCI Contract requires the conversion 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 
                                      
<PAGE>
 
have become standard in the wireline video industry. If an audit determines the
Company is not providing such an innovation and it fails to do so in the manner
and time period dictated 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, as well as new products and services, 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.

TCI AND AT&T MERGER
- -------------------
During the three months ended March 31, 1999 and 1998, revenues from TCI and
affiliated companies represented approximately 44.2% and 39.1% of total
revenues, respectively. The TCI Contract has minimum financial commitments over
the 15-year life of the contract and includes exclusive rights to provide
customer care and billing products and services for TCI's offerings of wireline
video, all Internet/high speed data services, residential wireline telephony
services, and print and mail services. As discussed above, the TCI Contract
provides certain performance criteria and other obligations to be met by the
Company. To date, the Company believes it has complied with the terms of the
contract. Since execution of the TCI Contract in September 1997 through March
31, 1999, the Company has successfully converted approximately 8.6 million TCI
cable television customers onto its system. Approximately, 1.7 million
additional TCI cable television customers are currently scheduled to be
converted during the remainder of 1999.

AT&T completed its merger with TCI in March 1999. At this time, it is too early
to determine the near- and long-term impact, if any, the merger will have on the
Company's relationship with the combined entity. AT&T has announced its planned
efforts to provide convergent communications services in 10 United States cities
during 1999. The Company is participating in those convergent trials and is
working closely with AT&T to provide customer care and billing services to
customers in those cities. The Company expects to continue performing
successfully under the TCI Contract, but its failure to do so 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 AND DBS INDUSTRIES
- -------------------------------------------------
The Company's business is concentrated in the cable television and Direct
Broadcast Satellite (DBS) industries, making the Company susceptible to a
downturn in those industries. During the years ended December 31, 1998 and 1997,
the Company derived 78% and 73%, and 13% and 11% of its total revenues from
companies in the U.S. cable television and U.S. DBS industries, respectively. A
decrease in the number of customers served by the Company's clients, loss of
business due to non-renewal of client 
                                      
<PAGE>
 
contracts, industry consolidation, and/or changing consumer demand for services
would adversely effect the results of operations of the Company.

There can be no assurance that new entrants into the cable television market
will become clients of the Company. Also, there can be no assurance that cable
television providers will be successful in expanding into other segments of the
converging communications markets. Even if major forays into new markets are
successful, the Company may be unable to meet the special billing and customer
care needs of that market. The cable television industry is undergoing
significant ownership changes at an accelerated pace. In addition, cable
television providers are consolidating, decreasing the potential number of
buyers for the Company's products and services. Consolidation in the industry
may put at risk the Company's ability to leverage its existing relationships.
Should this consolidation result in a concentration of cable television customer
accounts being owned by companies with whom the Company does not have a
relationship, or with whom competitors are entrenched, it could negatively
effect the Company's ability to maintain or expand its market share, thereby
adversely effecting the results of operations.

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 in sustaining and growing the annual revenue per
customer account 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. 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. Also, the introduction and
consumer acceptance of billing statements that are presented and paid
electronically over the Internet may happen more rapidly than the Company
anticipates. If electronic bill presentation and payment proliferates and the
Company is unable to respond with a solution quickly, such failure could have a
material adverse effect on the Company's results of operations.

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 solution for presenting multiple communications services on a single
bill, 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 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.

<PAGE>
 
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. 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, which
would adversely effect the Company's ability to meet its commitments and new
product delivery objectives.

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. The Company also holds a limited
number of patents on some of its newer products, and does not rely upon patents
as a primary means of protecting its rights in its intellectual property. 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 

<PAGE>
 
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. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations" for additional
discussion of the Company's efforts to address the year 2000 risks.

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.
