Exhibit 10.1

AGREEMENT

        THIS AGREEMENT (this "Agreement") is entered into as of April 30, 2002,
by and among CIBER, INC., a Delaware corporation ("CIBER"); DECISION
CONSULTANTS, INC., a Michigan corporation ("DCI"); KTR SYSTEM, L.P., a Texas
limited partnership and wholly-owned subsidiary of DCI ("KTR" and together with
DCI, the "Seller"); and THE JOHN A. KRASULA LIVING TRUST DATED APRIL 1, 1988,
JOHN A. KRASULA, SOLE TRUSTEE (the "Shareholder").

Recitals

        WHEREAS, CIBER, DCI, KTR and the Shareholder are parties to that Asset
Purchase Agreement dated April 30, 2002 (the "Purchase Agreement"). All
capitalized terms used but not defined herein shall have the meanings given to
those terms in the Purchase Agreement.

        WHEREAS, pursuant to the terms of the Purchase Agreement, at the
Closing, CIBER has agreed to issue to DCI 1,104,972 shares of CIBER Common Stock
(the "Shares").

        WHEREAS, the parties desire to provide for certain additional matters
relating to the Shares and otherwise, in connection with the transactions
contemplated by the Purchase Agreement, other than those addressed thereby.

Agreement

        NOW, THEREFORE, in consideration of the foregoing recitals and the
mutual agreements and covenants contained herein, the parties agree as follows:

        Effectiveness of Agreement.    This Agreement is entered into as of the
date first mentioned above but shall not become effective until the Closing of
the transactions contemplated by the Purchase Agreement. If the Closing does not
occur before May 31, 2002, then this Agreement shall become null and void and of
no effect, and no party hereto shall have any liability with respect to this
Agreement.

        Directed Issuance.    Seller agrees that effective at the Closing, it
will declare a bonus of 150,000 Shares (the "Longo Shares") payable to Ed Longo,
an employee of Seller ("Longo"). Seller hereby directs CIBER to issue the Longo
Shares directly to Ed Longo at the Closing in satisfaction of such bonus.

        Repurchase Option.    The 954,972 Shares that will be owned by Seller
following the issuance of the Longo Shares to Longo shall be referred to as the
"Seller Shares" and shall subject to the following rights and obligations:

        (a) Within five (5) business days following the expiration of the
Restricted Period, the Seller and the Shareholder shall notify the Company as to
how many of the Seller Shares continue to be owned by Seller or the Shareholder.
Failure to timely notify the Company shall not diminish Seller's or the
Shareholder's rights hereunder. Such actual number of shares, subject to a
maximum of 805,000 such shares, shall be referred to as the "Option Shares." The
Company hereby grants to Seller and the Shareholder the right to require the
Company to repurchase all or any lesser number of the Option Shares (the "Put
Option") and CIBER agrees to repurchase from Seller or the Shareholder, that
number of Option Shares as to which the Put Option is properly exercised, all
subject to the terms and conditions set forth above in this Section 3.

        (b) The Put Option becomes effective, subject to earlier termination
pursuant to Section 3(e) below, and may be exercised, on one or more occasions,
only during the period beginning at 12:01 a.m. (MST) on the 181st day following
the Closing Date and ending at 12:01 a.m. (MST) on the 186th day following the
Closing Date (such 5 day period being referred to as the "Exercise Period"). The
Put Option must be exercised by delivery of written notice to the Company of
Seller's or the Shareholder's

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

intent to exercise such option, specifying the number of Option Shares as to
which the election is being made (the "Put Shares").

        (c) In the event Seller or the Shareholder exercises the Put Option,
Seller or the Shareholder shall promptly (but in no event later than five (5)
days after delivery of the written notice of the election to exercise the Put
Option) tender to the Company a certificate or certificates representing the Put
Shares (duly endorsed for transfer or accompanied by a separate stock power).
The Company shall reasonably promptly (but in no event later than ten (10)
business days after delivery by Seller or the Shareholder of such
certificate(s)) tender to Seller or the Shareholder, as applicable, the
Aggregate Purchase Price (as defined below) in cash.

        (d) For purposes of this Agreement, "Aggregate Purchase Price" shall
mean (A) the average of (i) the closing sale price of CIBER Common Stock on the
NYSE on the Closing Date as reported in The Wall Street Journal, (the "Closing
Stock Price") and (ii) the highest closing sale price of CIBER Common Stock on
the NYSE on any day during the Restriction Period as reported in The Wall Street
Journal (such average, being the "Exercise Price") multiplied by (B) the number
of Put Shares.

        (e) The Put Option and any right to exercise the Put Option shall
immediately terminate upon the earliest occurrence of any of the following
events: (i) when Seller, the Shareholder or any Permitted Transferee is no
longer the record or beneficial owner of the Option Shares, (ii) the expiration
of 30 days following any five consecutive trading day period within the 90 day
period immediately following the Restricted Period, during which the closing
sale price of CIBER Common Stock on the NYSE as reported in The Wall Street
Journal exceeded the Exercise Price for any (provided that the Exercise Price is
greater than the Closing Stock Price), or (iii) upon expiration of the Exercise
Period if written notice of an election to exercise the Put Option has not been
delivered to the Company.

        (f) All amounts due under this Section 3 which are not timely paid shall
accrue interest at an annual rate of 8%. Any dispute arising out this Section 3
shall be resolved in the manner provided in Section 9.13 of the Purchase
Agreement.

        Indemnification.    Seller and the Shareholder, jointly and severally,
agree to indemnify CIBER, its officers, directors and agents (a "CIBER Party"),
from and against any loss, cost, liability or expense (including reasonable
attorneys' fees and the costs of any remedial action) reasonably incurred by a
CIBER Party, including, without limitation, both third-party and direct claims
(a "CIBER Loss"), directly or indirectly arising out of or in connection with
(i) the failure of CIBER, Seller or the Shareholder to deliver the Prospectus to
the security holders of Seller within the time period provided for and in the
manner prescribed by Form S-4, promulgated under the Securities Act; (ii) the
redemption of shares of Seller capital stock by Seller after the Closing; or
(iii) the dissolution or winding up of Seller and the liquidating distributions
made in connection therewith.

        Indemnification Procedures.

        (a)    Third Party Claims.    If a claim by a third party arises as to
which CIBER is entitled to indemnification from Seller or the Shareholder
hereunder, CIBER (the "Indemnified Party") shall endeavor to advise Seller or
the Shareholder (the "Indemnifying Party") of the claim within five business
days after receipt of a summons, or within ten (10) business days after receipt
of other written communication giving information as to the nature of the claim,
by the Indemnified Party, provided that failure to so notify shall not limit the
Indemnified Party's right to indemnification under Section 4 unless such failure
materially prejudices the ability of the Indemnifying Party to defend such third
party claim and then only to such extent. The Indemnifying Party shall not be
liable or responsible for any expenses which are incurred by the Indemnified
Party before such notice has been given to the Indemnifying Party, nor bound by
any settlements made by the Indemnified Party before such notice. The
Indemnifying Party shall, within the lesser of twenty (20) days after receipt of
notification of the claim from the Indemnified Party or five (5) days before an
answer is required to be filed, advise the Indemnified Party whether the
Indemnifying Party will undertake the defense of such claim on behalf of the
Indemnified Party and, if so, shall specify the name of the attorney who will
handle the matter, which attorney shall be reasonably satisfactory to the
Indemnified Party and shall not have any present

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

or potential conflict in representing the interests of both parties. If the
Indemnifying Party timely notifies the Indemnified Party that it will undertake
the defense of such claim and agrees that it is legally obligated to indemnify
the Indemnified Party hereunder and shall thereafter diligently provide such
defense, such counsel shall have control of the defense, but the Indemnified
Party may participate in the defense with its own counsel paid for by the
Indemnified Party, and the Indemnified Party shall not settle or compromise such
claim without the prior consent of the Indemnifying Party, which consent shall
not be unreasonably withheld. If the Indemnifying Party fails timely to advise
the Indemnified Party that it will undertake the defense of such claim on behalf
of the Indemnified Party, fails to agree that it is legally obligated to
indemnify the Indemnified Party hereunder or fails diligently to pursue such
defense, then the Indemnified Party may undertake the defense of such claim with
its own counsel and may settle or compromise such claim in its sole discretion,
all at the expense of the Indemnifying Party.

        (b)    Direct Claims.    Any indemnifiable claim hereunder by a party
hereto and that is not a claim by a third party shall be asserted by the
Indemnified Party by promptly delivering notice thereof to the Indemnifying
Party, provided that failure to so notify shall not limit the Indemnified
Party's right to indemnification under Section 4 unless such failure materially
prejudices the ability of the Indemnifying Party to remedy such claim and then
only to such extent. Such notice shall in good faith summarize the bases for the
claims for indemnification.

        Covenant Not to Sue.    Each of Seller and the Shareholder hereby
expressly agree not to, at any time, sue, protest, initiate, institute or assist
in instituting any proceeding, grievance, suit or investigation before any court
or other governmental authority related to any claim directly or indirectly
arising out of or in connection with (i) the failure of CIBER, Seller or the
Shareholder to deliver the Prospectus to the security holders of Seller within
the time period provided for as prescribed by Form S-4, promulgated under the
Securities Act; (ii) the redemption of shares of Seller capital stock by Seller
after the Closing; or (iii) the dissolution or winding up of Seller and the
liquidating distributions made in connection therewith.

        Authorization.    Each of Seller, the Shareholder and CIBER hereby
represent and warrant to each other that all action on the part of such party
necessary for the authorization, execution and delivery of this Agreement has
been taken and this Agreement constitutes a valid and legally binding obligation
of such party, enforceable against it in accordance with its terms, except to
the extent that such enforceability may be limited by applicable bankruptcy,
insolvency, fraudulent transfer, reorganization or similar laws affecting the
rights of creditors generally or by general principles of equity.

        Title to Shares.    Seller and the Shareholder represent and warrant to
CIBER that on the Put Option exercise date, if any, either Seller or the
Shareholder will have, good and marketable title to the Put Shares and, upon
delivery of such shares duly endorsed for transfer and receipt of the
consideration therefor, CIBER will acquire good and marketable title to the Put
Shares, free and clear of all liens, encumbrances, security interests,
restrictions and claims of any kind.

        Further Assurances.    Each party hereto agrees to do such other and
further acts and things, and to execute and deliver such additional instruments
and documents (not creating any obligations, or imposing any expenses,
additional to those otherwise created or imposed by this Agreement), as any
party may reasonably request from time to time in furtherance of the express
provisions of this Agreement.

        Binding Agreement.    This Agreement shall bind the parties hereto and
their respective heirs, executors, administrators, successors and assigns;
provided that this Agreement may not be assigned by Seller or the Shareholder.

        Entire Agreement.    This Agreement together with the Purchase Agreement
constitutes the entire agreement among the parties and supersedes any prior
understandings, agreements, or representations by or among the parties, written
or oral, to the extent they are related in any way to the subject matter hereof.

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

        Headings.    The section headings contained in this Agreement are
inserted for convenience only and shall not affect in any way the meaning or
interpretation of this Agreement.

        Governing Law.    This Agreement shall be governed by and construed in
accordance with the laws of the State of Colorado.

        Survival.    The representations and warranties of the parties set forth
herein shall survive the closing of the repurchase, if any, of the Option
Shares.

        Counterparts.    This Agreement may be executed in any number of
counterparts, and with counterpart signature pages, each of which shall be
deemed an original, and all of such counterparts together constitute but one and
the same agreement. One or more counterparts may be delivered by facsimile with
the same force and effect as an original.
