                              EMPLOYMENT AGREEMENT
                              --------------------

     This Employment Agreement is made and entered into on the 18/th/ day of
January, 2001, among CSG SYSTEMS INTERNATIONAL, INC. ("CSGS"), a Delaware
corporation, CSG SYSTEMS, INC. ("Systems"), a Delaware corporation, and PETER
KALAN (the "Executive"). CSGS and Systems collectively are referred to in this
Employment Agreement as the "Companies".

                                 * * *

     WHEREAS, Systems is a wholly-owned subsidiary of CSGS; and

     WHEREAS, the Executive currently is employed by Systems and serves as a
Vice President and the Chief Financial Officer of both of the Companies; and

     WHEREAS, the Companies desire to provide for the continued employment of
the Executive as a Vice President and their Chief Financial Officer; and

     WHEREAS, the Executive desires to accept such continued employment upon the
terms set forth in this agreement;

     NOW, THEREFORE, in consideration of the foregoing recitals and the
respective covenants and agreements of the parties contained in this document,
the Companies and the Executive agree as follows:

     1.   Employment and Duties.  Each of the Companies hereby employs the
          ---------------------
Executive as a Vice President and its Chief Financial Officer throughout the
term of this agreement and agrees to cause the Executive from time to time to be
elected or appointed to such corporate offices or positions.  The duties and
responsibilities of the Executive shall include the duties and responsibilities
of the Executive's corporate offices and positions referred to in the preceding
sentence which are set forth in the respective bylaws of the Companies from time
to time, general supervision of the financial affairs of the Companies, and such
other duties and responsibilities consistent with the Executive's corporate
offices and positions referred to in the preceding sentence and this agreement
which the Board of Directors of CSGS (the "Board") or the Chief Executive
Officer of CSGS from time to time may assign to the Executive.  If the Executive
is elected or appointed as a director of CSGS or Systems or as an officer or
director of any of the respective subsidiaries of the Companies during the term
of this agreement, then he also shall serve in such capacity or capacities but
without additional compensation.

     2.   Term.  The term of this agreement shall begin on January 1, 2001, and
          ----
shall continue thereafter through December 31, 2001, unless the Executive's
employment under this agreement is sooner terminated in accordance with this
agreement.  On December 31 of each year during the term of this agreement, as
extended from time to time pursuant to this sentence, beginning December 31,
2001, the term of this agreement automatically and without further action being
required shall be extended by one (1) year unless, not later than one (1) year
prior to a particular December 31, either CSGS notifies the Executive and
Systems in writing or the Executive notifies the Companies in writing that such
extension shall not occur on such December 31, in which latter case this
agreement shall terminate upon the expiration of its then current term,
<PAGE>

unless the Executive's employment under this agreement is sooner terminated in
accordance with this agreement. References in this agreement to the "current
term" of this agreement shall include both the original term of this agreement
and any automatic extensions of such term which actually have occurred pursuant
to this Paragraph 2.

     3.   Place of Employment.  Regardless of the location of the executive
          -------------------
offices of the Companies during the term of this agreement, the Companies shall
maintain a suitably staffed office for the Executive in the Denver, Colorado,
metropolitan area during the term of this agreement; and the Executive will not
be required without his consent to relocate or transfer his executive office or
principal residence from the immediate vicinity of the Denver, Colorado,
metropolitan area.

     4.   Base Salary.  For all services to be rendered by the Executive
          -----------
pursuant to this agreement, the Companies agree to pay the Executive during the
term of this agreement a base salary (the "Base Salary") at an annual rate of
not less than $225,000; provided, that the Base Salary as then in effect shall
be increased as of January 1 of each calendar year after 2001 during the term of
this agreement by at least the same percentage that the United States Department
of Labor Consumer Price Index (All Items) for All Urban Consumers, 1982-84=100
("CPI-U") for the November immediately preceding such January 1 increased over
the CPI-U for the November one year earlier.  The Board shall review the Base
Salary at least annually for the purpose of determining whether a Base Salary
increase greater than such CPI-U increase should be granted to the Executive for
a particular 12-month period.  The Executive's annual incentive bonus provided
for in Paragraph 5 and all other compensation and benefits to which the
Executive is or may become entitled pursuant to this agreement or under any
plans or programs of the Companies shall be in addition to the Base Salary.

     5.   Annual Incentive Bonus.  As soon as practicable after the execution of
          ----------------------
this agreement, the Board shall establish an incentive bonus program for the
Executive for 2001. Such incentive bonus program shall be reflected either in a
written supplement to this agreement signed by the Companies and the Executive
or in such other form as the Companies and the Executive may agree upon.  The
same procedure shall be followed for subsequent calendar years during the term
of this agreement, so that an annual incentive bonus program for the Executive
will be in effect throughout the term of this agreement.  The Executive and the
Companies understand and acknowledge that, among other things, such incentive
bonus program will involve achievement by the Companies of various financial
objectives, which may include but are not limited to revenues and earnings, and
also may include achievement by the Companies or the Executive of various non-
financial objectives.  Such incentive bonus program for each calendar year shall
provide the opportunity for the Executive to earn an incentive bonus of not less
than fifty percent (50%) of his Base Salary for such calendar year if the agreed
upon objectives are fully achieved.  The Board from time to time also may
establish incentive compensation programs for the Executive covering periods of
more than one (1) year, and any such programs shall be in addition to the annual
incentive bonus program required by this Paragraph 5.

     6.   Expenses.  During the term of this agreement, the Executive shall be
          --------
entitled to prompt reimbursement by the Companies of all reasonable ordinary and
necessary travel, entertainment, and other expenses incurred by the Executive
(in accordance with the policies and

                                       2
<PAGE>

procedures established by the Companies for their respective senior executive
officers) in the performance of his duties and responsibilities under this
agreement; provided, that the Executive shall properly account for such expenses
in accordance with the policies and procedures of the Companies, which may
include but are not limited to itemized accountings.

     7.   Other Benefits.  During the term of this agreement, the Companies
          --------------
shall provide to the Executive and his eligible dependents at the expense of the
Companies individual or group medical, hospital, dental, and long-term
disability insurance coverages and group life insurance coverage, in each case
at least as favorable as those coverages which are provided to other vice
presidents of the Companies.  During the term of this agreement, the Executive
also shall be entitled to participate in such other benefit plans or programs
which the Companies from time to time may make available to their employees
generally (except such programs, such as the 1996 Employee Stock Purchase Plan
of CSGS, in which executive officers of CSGS are not eligible to participate
because of securities law reasons).

     8.   Vacations and Holidays.  During the term of this agreement, the
          ----------------------
Executive shall be entitled to paid vacations and holidays in accordance with
the policies of the Companies in effect from time to time for their respective
senior executive officers, but in no event shall the Executive be entitled to
less than four (4) weeks of vacation during each calendar year.

     9.   Full-Time Efforts and Other Activities.  During the term of this
          --------------------------------------
agreement, to the best of his ability and using all of his skills, the Executive
shall devote substantially all of his working time and efforts during the normal
business hours of the Companies to the business and affairs of the Companies and
to the diligent and faithful performance of the duties and responsibilities
assigned to him pursuant to this agreement, except for vacations, holidays, and
sick days.  However, the Executive may devote a reasonable amount of his time to
civic, community, or charitable activities, to service on the governing bodies
or committees of trade associations or similar organizations of which either or
both of the Companies are members, and, with the prior approval of the Board or
the Chief Executive Officer of CSGS, to service as a director of other
corporations and to other types of activities not expressly mentioned in this
paragraph, so long as the activities referred to in this sentence do not
materially interfere with the proper performance of the Executive's duties and
responsibilities under this agreement.  The Executive also shall be free to
manage and invest his assets in such manner as will not require any substantial
services by the Executive in the conduct of the businesses or affairs of the
entities or in the management of the properties in which such investments are
made, so long as such activities do not materially interfere with the proper
performance of the Executive's duties and responsibilities under this agreement.

     10.  Termination of Employment.
          -------------------------

     (a)  Termination Because of Death.  The Executive's employment by the
          ----------------------------
Companies under this agreement shall terminate upon his death.  If the
Executive's employment under this agreement terminates because of his death,
then the Executive's estate or his beneficiaries (as the case may be) shall be
entitled to receive the following compensation and benefits from the Companies:

                                       3
<PAGE>

          (i)    The Base Salary through the date of the Executive's death;

          (ii)   A pro rata portion of the Executive's annual incentive bonus
                 for the calendar year in which his death occurs (computed as if
                 the Executive were employed by the Companies throughout such
                 calendar year), based upon the number of days in such calendar
                 year elapsed through the date of the Executive's death as a
                 proportion of 365, to be paid at the same time that such
                 incentive bonus would have been paid had the Executive's death
                 not occurred;

          (iii)  Any other amounts earned, accrued, or owed to the Executive
                 under this agreement but not paid as of the date of the
                 Executive's death; and

          (iv)   Any other benefits payable by reason of the Executive's death,
                 or to which the Executive otherwise may be entitled, under any
                 benefit plans or programs of the Companies in effect on the
                 date of the Executive's death.

     (b)  Termination Because of Disability.  If the Executive becomes incapable
          ---------------------------------
by reason of physical injury, disease, or mental illness of substantially
performing his duties and responsibilities under this agreement for a continuous
period of six (6) months or more or for more than one hundred eighty (180) days
in the aggregate (whether or not consecutive) during any 12-month period, then
at any time after the elapse of such six-month period or such 180 days, as the
case may be, the Board may terminate the Executive's employment by the Companies
under this agreement.  If the Executive's employment under this agreement is
terminated by the Board because of such disability on the part of the Executive,
then the Executive shall be entitled to receive the following compensation and
benefits from the Companies:

          (i)    The Base Salary through the effective date of such termination;

          (ii)   A pro rata portion of the Executive's annual incentive bonus
                 for the calendar year in which such termination occurs
                 (computed as if the Executive were employed by the Companies
                 throughout such calendar year), based upon the number of days
                 in such calendar year elapsed through the effective date of
                 such termination as a proportion of 365, to be paid at the same
                 time that such incentive bonus would have been paid if such
                 termination had not occurred;

          (iii)  Any other amounts earned, accrued, or owed to the Executive
                 under this agreement but not paid as of the effective date of
                 such termination;

                                       4
<PAGE>

          (iv)   Continued participation in the following benefit plans or
                 programs of the Companies which may be in effect from time to
                 time and in which the Executive was participating as of the
                 effective date of such termination, to the extent that such
                 continued participation by the Executive is permitted under the
                 terms and conditions of such plans (unless such continued
                 participation is restricted or prohibited by applicable
                 governmental regulations governing such plans), until the first
                 to occur of the cessation of such disability, the Executive's
                 death, the Executive's attainment of age sixty-five (65), or
                 (separately with respect to the termination of each benefit)
                 the provision of a substantially equivalent benefit to the
                 Executive by another employer of the Executive:

                    (1) Group medical and hospital insurance,
                    (2) Group dental insurance,
                    (3) Group life insurance, and
                    (4) Group long-term disability insurance;

                 and

          (v)    Any other benefits payable by reason of the Executive's
                 disability, or to which the Executive otherwise may be
                 entitled, under any benefit plans or programs of the Companies
                 in effect on the effective date of such termination.

For purposes of this subparagraph (b), decisions with respect to the Executive's
disability shall be made by the Board, using its reasonable good faith judgment;
and, in making any such decision, the Board shall be entitled to rely upon the
opinion of a duly licensed and qualified physician selected by a majority of the
members of the Board who are not employees of either of the Companies or any of
their respective subsidiaries.

     (c)  Termination for Cause.  The Board may terminate the Executive's
          ---------------------
employment by the Companies under this agreement for cause; however, for
purposes of this agreement "cause" shall mean only (i) the Executive's
confession or conviction of theft, fraud, embezzlement, or other crime involving
dishonesty, (ii) the Executive's excessive absenteeism (other than by reason of
physical injury, disease, or mental illness) without a reasonable justification,
(iii) material violation by the Executive of the provisions of Paragraph 11,
(iv) habitual and material negligence by the Executive in the performance of his
duties and responsibilities under or pursuant to this agreement and failure on
the part of the Executive to cure such negligence within twenty (20) days after
his receipt of a written notice from the Board or the Chief Executive Officer of
CSGS setting forth in reasonable detail the particulars of such negligence, (v)
material non-compliance by the Executive with his obligations under Paragraph 9
and failure to correct such non-compliance within

                                       5
<PAGE>

twenty (20) days after his receipt of a written notice from the Board or the
Chief Executive Officer of CSGS setting forth in reasonable detail the
particulars of such non-compliance, (vi) material failure by the Executive to
comply with a lawful directive of the Board or the Chief Executive Officer of
CSGS and failure to cure such non-compliance within twenty (20) days after his
receipt of a written notice from the Board or the Chief Executive Officer of
CSGS setting forth in reasonable detail the particulars of such non-compliance,
(vii) a material breach by the Executive of any of his fiduciary duties to the
Companies and, if such breach is curable, the Executive's failure to cure such
breach within ten (10) days after his receipt of a written notice from the Board
or the Chief Executive Officer of CSGS setting forth in reasonable detail the
particulars of such breach, or (viii) willful misconduct or fraud on the part of
the Executive in the performance of his duties under this agreement. In no event
shall the results of operations of the Companies or any business judgment made
in good faith by the Executive constitute an independent basis for termination
for cause of the Executive's employment under this agreement. Any termination of
the Executive's employment for cause must be authorized by a majority vote of
the Board taken not later than nine (9) months after a majority of the members
of the Board (other than the Executive) have actual knowledge of the occurrence
of the event or conduct constituting the cause for such termination. If the
Executive's employment under this agreement is terminated by the Board for
cause, then the Executive shall be entitled to receive the following
compensation and benefits from the Companies:

          (i)    The Base Salary through the effective date of such termination;

          (ii)   Any other amounts earned, accrued, or owed to the Executive
                 under this agreement but not paid as of the effective date of
                 such termination; and

          (iii)  Any other benefits payable to the Executive upon his
                 termination for cause, or to which the Executive otherwise may
                 be entitled, under any benefit plans or programs of the
                 Companies in effect on the effective date of such termination.

     (d)  Termination Without Cause Prior to a Change of Control.  If, prior to
          ------------------------------------------------------
the occurrence of a Change of Control, the Companies terminate the Executive's
employment under this agreement for any reason other than cause or the
Executive's death or disability, then the Executive shall be entitled to receive
the following compensation, benefits, and other payments from the Companies:

          (i)    The Base Salary through that date which is one (1) year after
                 the effective date of such termination (the "Ending Date"), to
                 be paid at the same times that the Base Salary would have been
                 paid if such termination had not occurred; provided, that if
                 the Executive commences employment with another employer,
                 whether as an employee or as a consultant, prior to the Ending
                 Date (for purposes of this Paragraph 10, the "Other
                 Employment"), then such payments of the Base Salary shall be
                 reduced from time to time by the aggregate amount of salary,
                 cash bonus, and consulting fees received or receivable by the
                 Executive from the Other Employment for services performed by
                 him during the period from the commencement of the Other
                 Employment through the Ending Date;

                                       6
<PAGE>

          (ii)   The Executive's annual incentive bonus for the calendar year in
                 which such termination occurs (computed as if the Executive
                 were employed by the Companies throughout such calendar year),
                 to be paid at the same time that such incentive bonus would
                 have been paid if such termination had not occurred and to be
                 no less than the Executive's annual incentive bonus for the
                 calendar year immediately preceding the calendar year in which
                 such termination occurs;

          (iii)  An amount equal to fifty percent (50%) of the Base Salary in
                 effect on the effective date of such termination, such amount
                 to be paid, without interest, one year after the effective date
                 of such termination.

          (iv)   Any other amounts earned, accrued, or owed to the Executive
                 under this agreement but not paid as of the effective date of
                 such termination;

          (v)    Continued participation in the following benefit plans or
                 programs of the Companies which may be in effect from time to
                 time and in which the Executive was participating as of the
                 effective date of such termination, to the extent that such
                 continued participation by the Executive is permitted under the
                 terms and conditions of such plans (unless such continued
                 participation is restricted or prohibited by applicable
                 governmental regulations governing such plans), until the first
                 to occur of the Ending Date or (separately with respect to the
                 termination of each benefit) the provision of a substantially
                 equivalent benefit to the Executive by another employer of the
                 Executive:

                    (1)  Group medical and hospital insurance,
                    (2)  Group dental insurance,
                    (3)  Group life insurance, and
                    (4)  Group long-term disability insurance;

                 and

          (vi)   Any other benefits payable to the Executive upon his
                 termination without cause, or to which the Executive otherwise
                 may be entitled, under any benefit plans or programs of the
                 Companies in effect on the effective date of such termination.

     (e)  Termination Without Cause After a Change of Control.  If, after the
          ---------------------------------------------------
occurrence of a Change of Control, the Companies or any Permitted Assignee
terminates the Executive's employment under this agreement for any reason other
than cause or the Executive's death or disability, then the Executive shall be
entitled to receive from the Companies and the Permitted

                                       7
<PAGE>

Assignee, if any (all of whom shall be jointly and severally liable therefor),
all of the compensation, benefits, and other payments from the Companies which
are described and provided for in subparagraph (d) of this Paragraph 10 (as
modified by this subparagraph (e)); provided, however, that (i) for purposes of
this subparagraph (e) the Ending Date shall be two (2) years after the effective
date of such termination, and the aggregate Base Salary payable under
subparagraph (d)(i) (as modified by this subparagraph (e)) for all periods
through the Ending Date shall be paid to the Executive in a lump sum without
regard to Other Employment not later than thirty (30) days after the effective
date of such termination, (ii) the minimum annual incentive bonus payable under
subparagraph (d)(ii) shall be paid to the Executive not later than thirty (30)
days after the effective date of such termination (with any balance of such
annual incentive bonus being payable as provided in such subparagraph (d)(ii)),
and (iii) the amount payable under subparagraph (d)(iii) (as modified by this
subparagraph (e)) shall be one hundred percent (100%) of the Base Salary in
effect on the effective date of such termination and shall be paid to the
Executive in a lump sum not later than thirty (30) days after the effective date
of such termination.

     (f)  Constructive Termination.  If at any time during the term of this
          ------------------------
agreement the Board, the Chief Executive Officer of CSGS, or a Permitted
Assignee materially alters the duties and responsibilities of the Executive
provided for in Paragraph 1 or assigns to the Executive duties and
responsibilities materially inappropriate to the chief financial officer of the
Companies without the Executive's written consent, then, at the election of the
Executive (such election to be made by written notice from the Executive to the
Board or the Permitted Assignee, as may be appropriate in the circumstances),
(i) such action by the Board, the Chief Executive Officer of CSGS, or such
Permitted Assignee shall constitute a constructive termination of the
Executive's employment by the Companies for a reason other than cause (the
"Constructive Termination"), (ii) the Executive thereupon may resign from his
offices and positions with the Companies and shall not be obligated to perform
any further services of any kind to or for the Companies, and (iii) the
Executive shall be entitled to receive from the Companies (and the Permitted
Assignee, if applicable) at the applicable times all of the compensation,
benefits, and other payments described in subparagraph (d) or subparagraph (e)
of this Paragraph 10 (whichever may be applicable), as if the effective date of
the Executive's resignation were the effective date of his termination of
employment for purposes of determining such compensation, benefits, and other
payments.  Notwithstanding the foregoing provisions of this subparagraph (f),
before exercising any of his rights pursuant to the preceding sentence, the
Executive shall give written notice to the Chief Executive Officer of CSGS
setting forth the Executive's intent to exercise such rights and specifying the
Constructive Termination which the Executive claims to be the basis for such
intended exercise; and the Companies shall have twenty (20) days after the Chief
Executive Officer has received such notice to take such actions, if any, as the
Companies may deem appropriate to eliminate such claimed Constructive
Termination (without thereby admitting that a Constructive Termination had
occurred).  If the Companies so act to eliminate such claimed Constructive
Termination, then the Executive shall not have any rights under this
subparagraph (f) with respect to such claimed Constructive Termination.

     (g)  Voluntary Resignation.  If the Executive voluntarily resigns as an
          ---------------------
employee of the Companies and thereby voluntarily terminates his employment
under this agreement and if none of subparagraphs (a) through (f) of this
Paragraph 10 is applicable to such termination, then the

                                       8
<PAGE>

Executive shall be entitled to receive only the following compensation,
benefits, and other payments from the Companies:

          (i)    The Base Salary through the effective date of such voluntary
                 resignation;

          (ii)   Any other amounts earned, accrued, or owed to the Executive
                 under this agreement but not paid as of the effective date of
                 such voluntary resignation;

          (iii)  If (and only if) the Executive's voluntary resignation is
                 effective on December 31 of a particular calendar year, the
                 Executive's annual incentive bonus (if any) for such calendar
                 year, to be paid in accordance with the regular schedule for
                 its payment; and

          (iv)   Any other benefits payable to the Executive upon his voluntary
                 resignation, or to which the Executive otherwise may be
                 entitled, under any benefit plans or programs of the Companies
                 in effect on the effective date of such voluntary resignation.

The Executive understands and agrees that if this subparagraph (g) is applicable
to the termination of the Executive's employment with the Companies, then,
unless his voluntary resignation is effective on December 31 of a particular
calendar year, the Executive will not be entitled to any annual incentive bonus
for the calendar year in which his voluntary resignation becomes effective.

     (h)  Liquidated Damages.  The Executive agrees to accept the compensation,
          ------------------
benefits, and other payments provided for in subparagraph (d), subparagraph (e),
or subparagraph (f) of this Paragraph 10, as the case may be, as full and
complete liquidated damages for any breach of this agreement resulting from the
actual or constructive termination of the Executive's employment under this
agreement for a reason other than cause or the Executive's death or disability;
and the Executive shall not have and hereby waives and relinquishes any other
rights or claims in respect of such breach.

     (i)  Notice of Other Employment and of Benefits.  The Executive promptly
          ------------------------------------------
shall notify the Companies in writing of (i) his acceptance of the Other
Employment referred to in subparagraph (d) of this Paragraph 10, (ii) the
effective date of such Other Employment, and (iii) the amount of salary, cash
bonus, and consulting fees which the Executive receives or is entitled to
receive from the Other Employment for services performed by him during the
period from the commencement of the Other Employment through the Ending Date.
Whenever relevant for purposes of this Paragraph 10, the Executive also promptly
shall notify the Companies of his receipt from another employer of any benefits
of the types referred to in subparagraphs (b)(iv) and (d)(v) of this Paragraph
10.  Such information shall be updated by the Executive whenever necessary to
keep the Companies informed on a current basis.

                                       9
<PAGE>

     (j)  Modification of Benefit Plans or Programs.  Nothing contained in this
          -----------------------------------------
Paragraph 10 shall obligate the Companies to institute, maintain, or refrain
from changing, amending, or discontinuing any benefit plan or program referred
to in subparagraph (b)(iv) or (d)(v) of this Paragraph 10 so long as such
actions are similarly applicable to senior executives of the Companies
generally.

     (k)  Rights of Estate.  If the Executive dies prior to his receipt of all
          ----------------
of the cash payments to which he may be entitled pursuant to subparagraph (b),
(c), (d), (e), (f), or (g) of this Paragraph 10 if any such subparagraph becomes
applicable, then the unpaid portion of such cash payments shall be paid by the
Companies to the personal representative of the Executive's estate at the same
time or times that the payments would have been made to the Executive if he
still were living.

     (l)  Excess Parachute Payments.  If any of the payments required to be made
          -------------------------
to the Executive pursuant to subparagraph (d), (e), or (f) of this Paragraph 10
constitute "excess parachute payments" within the meaning of Section 280G of the
Internal Revenue Code of 1986, as amended, and any regulations thereunder, and
the Executive becomes liable for any excise tax on such "excess parachute
payments" and any interest or penalties thereon (such excise tax, interest, and
penalties, collectively, the "Tax Penalties"), then the Companies (and the
Permitted Assignee, if applicable) promptly shall make a cash payment (the
"Additional Payment") to the Executive in an amount equal to the Tax Penalties.
The Companies also promptly shall make an additional cash payment to the
Executive in an amount rounded to the nearest $100.00 which is equal to any
additional income, excise, and other taxes (using the individual tax rates
applicable to the Executive for the year for which such Tax Penalties are owed)
for which the Executive will be liable as a result of the Executive's receipt of
the Additional Payment (the additional cash payment provided for in this
sentence being referred to as a "Gross-Up Payment").  In addition, the Executive
shall be entitled to promptly receive from the Companies (and the Permitted
Assignee, if applicable) a further Gross-Up Payment in respect of each prior
Gross-Up Payment until the amount of the last Gross-Up Payment is less than
$100.00.

     11.  Nondisclosure.  During the term of this agreement and thereafter, the
          -------------
Executive shall not, without the prior written consent of the Board or a person
(other than the Executive) so authorized by the Board, disclose or use for any
purpose (except in the course of his employment under this agreement and in
furtherance of the business of the Companies or any of their respective
subsidiaries) any confidential information, trade secrets, or proprietary data
of the Companies or any of their respective subsidiaries (collectively, for
purposes of this agreement, "Confidential Information"); provided, however, that
Confidential Information shall not include any information then known generally
to the public or ascertainable from public or published information (other than
as a result of unauthorized disclosure by the Executive) or any information of a
type not otherwise considered confidential by persons engaged in the same
business or a business similar to that conducted by the Companies or their
respective subsidiaries, as the case may be.

     12.  Successors and Assigns.  This agreement and all rights under this
          ----------------------
agreement shall be binding upon, inure to the benefit of, and be enforceable by
the parties hereto and their respective personal or legal representatives,
executors, administrators, heirs, distributees, devisees, legatees, successors,
and assigns.  This agreement is personal in nature, and none of the parties to
this

                                       10
<PAGE>

agreement shall, without the written consent of the others, assign or transfer
this agreement or any right or obligation under this agreement to any other
person or entity, except as permitted by Paragraph 14.

     13.   Notices.  For purposes of this agreement, notices and other
           -------

                                Englewood, Colorado  80111
                                Attn: Chief Executive Officer,

or to such other address as either party may have furnished to the other party

communications shall be effective only upon receipt.

     14.   Merger, Consolidation, Sale of Assets.  In the event of (a) a merger
           -------------------------------------
of Systems with another corporation (other than CSGS) in a transaction in which
Systems is not the surviving corporation, (b) the consolidation of Systems into
a new corporation resulting from such consolidation, (c) the sale or other
disposition of all or substantially all of the assets of Systems, the Companies
may assign this agreement and all of the rights and obligations of the Companies
under this agreement to the surviving, resulting, or acquiring entity (for
purposes of this agreement, a "Permitted Assignee"); provided, that such
surviving, resulting, or acquiring entity shall in writing assume and agree to
perform all of the obligations of the Companies under this agreement; and
provided further, that the Companies shall remain jointly and severally liable
for the performance of the obligations of the Companies under this agreement in
the event of a failure of the Permitted Assignee to perform its obligations
under this agreement.

     15.   Change of Control.  For purposes of this agreement, a "Change of
           -----------------
Control" shall be deemed to have occurred upon the happening of any of the
following events:

     (a)   CSGS is merged or consolidated into another corporation, and
           immediately after such merger or consolidation becomes effective the
           holders of a majority of the outstanding shares of voting capital
           stock of CSGS immediately prior to the effectiveness of such merger
           or consolidation do not own (directly or indirectly) a majority of
           the outstanding shares of voting capital stock of the surviving or
           resulting corporation in such merger or consolidation,

                                       11
<PAGE>

     (b)  CSGS ceases to own (directly or indirectly) a majority of the
          outstanding shares of voting capital stock of Systems (unless such
          event results from the merger of Systems into CSGS, with no change in
          the ownership of the voting capital stock of CSGS, or from the
          dissolution of Systems and the continuation of its business by CSGS),

     (c)  Systems is merged or consolidated into a corporation other than CSGS,
          and at any time after such merger or consolidation becomes effective
          CSGS does not own (directly or indirectly) a majority of the
          outstanding shares of voting capital stock of the surviving or
          resulting corporation in such merger or consolidation,

     (d)  the stockholders of Systems vote (or act by written consent) to
          dissolve Systems (unless the business of Systems will be continued by
          CSGS) or to sell or otherwise dispose of all or substantially all of
          the property and assets of Systems (other than to an entity or group
          of entities which is then under common ownership (directly or
          indirectly) with Systems),

     (e)  any person, entity, or group of persons within the meaning of Sections
          13(d) or 14(d) of the Securities Exchange Act of 1934 (the "1934 Act")
          and the rules promulgated thereunder becomes the beneficial owner
          (within the meaning of Rule 13d-3 under the 1934 Act) of thirty
          percent (30%) or more of the outstanding voting capital stock of CSGS,
          or

     (f)  during any period of two consecutive years or less, individuals who at
          the beginning of such period constituted the Board of Directors of
          CSGS cease, for any reason, to constitute at least a majority of the
          Board of Directors of CSGS, unless the election or nomination for
          election of each new director of CSGS who took office during such
          period was approved by a vote of at least seventy-five percent (75%)
          of the directors of CSGS still in office at the time of such election
          or nomination for election who were directors of CSGS at the beginning
          of such period.

     16.  Miscellaneous.  No provision of this agreement may be modified,
          -------------
waived, or discharged unless such waiver, modification, or discharge is agreed
to in writing and is signed by the Executive and an officer of CSGS (other than
the Executive) so authorized by the Board.  No waiver by any party to this
agreement at any time of any breach by any other party of, or compliance by any
other party with, any condition or provision of this agreement to be performed
by such other party shall be deemed to be a waiver of similar or dissimilar
provisions or conditions at the same or any prior or subsequent time.  No
agreements or representations, oral or otherwise, express or implied, with
respect to the subject matter of this agreement have been made by any party that
are not expressly set forth in this agreement.

     17.  Representations of Companies.  The Companies severally represent and
          ----------------------------
warrant to the Executive that they have full legal power and authority to enter
into this agreement, that the execution and delivery of this agreement by the
Companies have been duly authorized by their

                                       12
<PAGE>

respective boards of directors, and that the performance of their respective
obligations under this agreement will not violate any agreement between the
Companies, or either of them, and any other person, firm, or organization.

     18.   Non-Solicitation of Employees.  For a period of one (1) year after
           -----------------------------
the effective date of the termination of the Executive's employment under this
agreement for any reason, whether voluntarily or involuntarily and with or
without cause, without the prior written consent of CSGS the Executive agrees
(i) not to directly or indirectly employ, solicit for employment, assist any
other person in employing or soliciting for employment, or advise or recommend
to any other person that such other person employ or solicit for employment any
person who then is an employee of the Companies (or either of them) or any of
the respective subsidiaries of the Companies and (ii) not to recommend to any
then employee of the Companies (or either of them) or any of the respective
subsidiaries of the Companies that such employee leave the employ of such
employer.

     19.   Post-Termination Noncompetition.  Because the Confidential
           -------------------------------
Information known to or developed by the Executive during his employment by the
Companies encompasses at the highest level information concerning the plans,
strategies, products, operations, and existing and prospective customers of the
Companies and could not practically be disregarded by the Executive, the
Executive acknowledges that his provision of executive services to a competitor
of the Companies or either of them soon after the termination of the Executive's
employment by the Companies would inevitably result in the use of the
Confidential Information by the Executive in his performance of such executive
services, even if the Executive were to use his best efforts to avoid such use
of the Confidential Information.  To prevent such use of the Confidential
Information and the resulting unfair competition and wrongful appropriation of
the goodwill and other valuable proprietary interests of the Companies, the
Executive agrees that for a period of one (1) year after the termination of his
employment by the Companies for any reason, whether voluntarily or involuntarily
and with or without cause, the Executive will not, directly or indirectly:

           (a)  engage, whether as an employee, agent, consultant, independent
                contractor, owner, partner, member, or otherwise, in a business
                activity which then competes in a material way with a business
                activity then being actively engaged in by the Companies or
                either of them;

           (b)  solicit or recommend to any other person that such period
                solicit any then customer of the Companies or either or them,
                which customer also was a customer of the Companies or either of
                them at any time during the one (1) year period prior to the
                termination of the Executive's employment by the Companies, for
                the purpose of obtaining the business of such customer in
                competition with the Companies or either of them; or

          (c)   induce or attempt to induce any then customer or prospective
                customer of the Companies or either of them to terminate or not
                commence a business relationship with the Companies or either of
                them.

                                       13
<PAGE>

The Companies and the Executive acknowledge and agree that the restrictions
contained in this Paragraph 19 are both reasonable and necessary in view of the
Executive's positions with the Companies and that the Executive's compensation
and benefits under this agreement are sufficient consideration for the
Executive's acceptance of such restrictions.  Nevertheless, if any of the
restrictions contained in this Paragraph 19 are found by a court having
jurisdiction to be unreasonable, or excessively broad as to geographic area or
time, or otherwise unenforceable, then the parties intend that the restrictions
contained in this Paragraph 19 be modified by such court so as to be reasonable
and enforceable and, as so modified by the court, be fully enforced.  Nothing
contained in this paragraph shall be construed to preclude the investment by the
Executive of any of his assets in any publicly owned entity so long as the
Executive has no direct or indirect involvement in the business of such entity
and owns less than 2% of the voting equity securities of such entity.  Nothing
contained in this paragraph shall be construed to preclude the Executive from
becoming employed by or serving as a consultant to or having dealings with a
publicly owned entity one of whose businesses is a competitor of the Companies
or either of them so long as such employment, consultation, or dealings do not
directly or indirectly involve or relate to the business of such entity which is
a competitor of the Companies or either of them.

     20.   Joint and Several Obligations.  All of the obligations of the
           -----------------------------
Companies under this agreement are joint and several; and neither the
bankruptcy, insolvency, dissolution, merger, consolidation, or reorganization
nor the cessation of business or corporate existence of one of the Companies
shall affect, impair, or diminish the obligations under this agreement of the
other of the Companies.  The compensation and benefits to which the Executive is
entitled under this agreement are aggregate compensation and benefits, and the
payment of such compensation or the provision of such benefits by one of the
Companies shall to the extent of such payment or provision satisfy the
obligations of the other of the Companies.  The Companies may agree between
themselves as to which of them will be responsible for some or all of the
Executive's compensation and benefits under this agreement, but any such
agreement between the Companies shall not diminish to any extent the joint and
several liability of the Companies to the Executive for all of such compensation
and benefits.

     21.   Injunctive Relief.  The Executive acknowledges that his violation of
           -----------------
the provisions and restrictions contained in Paragraphs 11, 18, and 19 could
cause significant injury to the Companies for which the Companies would have no
adequate remedy at law.  Accordingly, the Executive agrees that the Companies
will be entitled, in addition to any other rights and remedies that then may be
available to the Companies, to seek and obtain injunctive relief to prevent any
breach or potential breach of any of the provisions and restrictions contained
in Paragraph 11, 18, or 19.

     22.   Dispute Resolution.  Subject to the provisions of Paragraph 21, any
           ------------------
claim by the Executive or the Companies arising from or in connection with this
agreement, whether based on contract, tort, common law, equity, statute,
regulation, order, or otherwise (a "Dispute"), shall be resolved as follows:

     (a)   Such Dispute shall be submitted to mandatory and binding
           arbitration at the election of either the Executive or the particular
           Company involved (the "Disputing Party"). Except as otherwise
           provided in this Paragraph 22, the arbitration shall be pursuant to
           the Commercial Arbitration Rules of the American Arbitration
           Association (the "AAA").

                                       14
<PAGE>

     (b)   To initiate the arbitration, the Disputing Party shall notify the
           other party in writing within 30 days after the occurrence of the
           event or events which give rise to the Dispute (the "Arbitration
           Demand"), which notice shall (i) describe in reasonable detail the
           nature of the Dispute, (ii) state the amount of any claim, (iii)
           specify the requested relief, and (iv) name an arbitrator who (A) has
           been licensed to practice law in the U.S. for at least ten years, (B)
           has no past or present relationship with either the Executive or the
           Companies, and (C) is experienced in representing clients in
           connection with employment related disputes (the "Basic
           Qualifications"). Within fifteen (15) days after the other party's
           receipt of the Arbitration Demand, such other party shall serve on
           the Disputing Party a written statement (i) answering the claims set
           forth in the Arbitration Demand and including any affirmative
           defenses of such party, (ii) asserting any counterclaim, which
           statement shall (A) describe in reasonable detail the nature of the
           Dispute relating to the counterclaim, (B) state the amount of the
           counterclaim, and (C) specify the requested relief, and (iii) naming
           a second arbitrator satisfying the Basic Qualifications. Promptly,
           but in any event within five (5) days thereafter, the two arbitrators
           so named shall select a third neutral arbitrator from a list provided
           by the AAA of potential arbitrators who satisfy the Basic
           Qualifications and who have no past or present relationship with the
           parties' counsel, except as otherwise disclosed in writing to and
           approved by the parties. The arbitration will be heard by a panel of
           the three arbitrators so chosen (the "Arbitration Panel"), with the
           third arbitrator so chosen serving as the chairperson of the
           Arbitration Panel. Decisions of a majority of the members of the
           Arbitration Panel shall be determinative.

     (c)   The arbitration hearing shall be held in Denver, Colorado. The
           Arbitration Panel is specifically authorized to render partial or
           full summary judgment as provided for in the Federal Rules of Civil
           Procedure. The Arbitration Panel will have no power or authority,
           under the Commercial Arbitration Rules of the AAA or otherwise, to
           relieve the parties from their agreement hereunder to arbitrate or
           otherwise to amend or disregard any provision of this agreement,
           including, without limitation, the provisions of this Paragraph 22.

     (d)   If an arbitrator refuses or is unable to proceed with arbitration
           proceedings as called for by this Paragraph 22, such arbitrator shall
           be replaced by the party who selected such arbitrator or, if such
           arbitrator was selected by the two party-appointed arbitrators, by
           such two party-appointed arbitrators' selecting a new third
           arbitrator in accordance with Paragraph 22(b), in either case within
           five (5) days after such declining or withdrawing arbitrator's giving
           notice of refusal or inability to proceed. Each such replacement
           arbitrator shall satisfy the Basic Qualifications. If an arbitrator
           is replaced pursuant to this Paragraph 22(d) after the arbitration
           hearing has commenced, then a rehearing shall take place in
           accordance with the provisions of this Paragraph 22(d) and the
           Commercial Arbitration Rules of the AAA.

                                       15
<PAGE>

     (e)   Within ten (10) days after the closing of the arbitration hearing,
           the Arbitration Panel shall prepare and distribute to the parties a
           writing setting forth the Arbitration Panel's finding of facts and
           conclusions of law relating to the Dispute, including the reason for
           the giving or denial of any award. The findings and conclusions and
           the award, if any, shall be deemed to be confidential information.

     (f)   The Arbitration Panel is instructed to schedule promptly all
           discovery and other procedural steps and otherwise to assume case
           management initiative and control to effect an efficient and
           expeditious resolution of the Dispute. The Arbitration Panel is
           authorized to issue monetary sanctions against either party if, upon
           a showing of good cause, such party is unreasonably delaying the
           proceeding.

     (g)   Any award rendered by the Arbitration Panel will be final,
           conclusive, and binding upon the parties, and any judgment on such
           award may be entered and enforced in any court of competent
           jurisdiction.

     (h)   Each party will bear a pro rata share of all fees, costs, and
           expenses of the arbitrators; and, notwithstanding any law to the
           contrary, each party will bear all of the fees, costs, and expenses
           of his or its own attorneys, experts, and witnesses. However, in
           connection with any judicial proceeding to compel arbitration
           pursuant to this agreement or to enforce any award rendered by the
           Arbitration Panel, the prevailing party in such a proceeding will be
           entitled to recover reasonable attorneys' fees and expenses incurred
           in connection with such proceedings, in addition to any other relief
           to which such party may be entitled.

     (i)   Nothing contained in the preceding provisions of this Paragraph 22
           shall be construed to prevent either party from seeking from a court
           a temporary restraining order or other injunctive relief pending
           final resolution of a Dispute pursuant to this Paragraph 22.

     23.   No Duty to Seek Employment.  The Executive shall not be under any
           --------------------------
duty or obligation to seek or accept other employment following the termination
of his employment by the Companies; and, except as expressly provided in
subparagraphs (b)(iv), (d)(i), and (d)(v) of Paragraph 10, no amount, payment,
or benefit due the Executive under this agreement shall be reduced, suspended,
