liabilities and obligations of DataFocus relating to or arising with respect to
periods from and after the Closing Date (as defined in paragraph 9) under the
Contracts listed on Exhibit B. DataFocus hereby agrees to retain and discharge,
and to indemnify and hold CIBER harmless from and against, any and all debts,
liabilities and obligations, including taxes, of DataFocus relating to or
arising with respect to periods prior to the Closing Date and any debt,
liability or obligation of DataFocus not expressly assumed hereby, whenever
arising, including, without limitations, any debt, liability or obligation of
DataFocus pursuant to any "employee pension benefit plans" (as that term is
defined under Section 3(2) of the Employee Retirement Income Security Act of
1974, as amended ("ERISA")), "employee welfare benefit plans" (as that term is
defined under Section 3(1) of ERISA) and any other plans, programs, practices,
policies or arrangements providing benefits for any or all of the present or
past employees of the Business, DataFocus or any organization which is a member
of a controlled group of organizations with DataFocus (within the meaning of
Section 414(b), (c), (m) or (o) of the Internal Revenue Code of 1986, as
amended) (a "Commonly Controlled Entity") which are in effect as of the date
hereof or under which DataFocus has or will have any obligations or liabilities.

            5. Allocation of Purchase Price. The parties agree that the purchase
price paid pursuant to paragraph 3 shall be allocated among the Assets pursuant
to Section 1060 of the Internal Revenue Code of 1986, as amended (the "Code"),
in accordance with Exhibit E attached hereto to which CIBER and DataFocus have
mutually agreed. DataFocus and CIBER agree to report the federal, state and
local income and other tax consequences of the transactions contemplated hereby,
and in particular to report the information required by Section 1060(b) of the
Code, in a manner consistent with the agreed upon allocation, and to file all
other applicable tax returns and forms to reflect such purchase price
allocation. Within 240 days following the Closing Date, CIBER and DataFocus
shall have agreed as to the content of the IRS Form 8594 to be filed by each of
them with their next income tax returns, and will not take any position
inconsistent therewith (except to correct any error) upon examination of any tax
return, in any refund claim, in any litigation, investigation or otherwise.

         6. Revenues; Expenses.

            (a) From and after the Closing Date, CIBER shall use reasonable
efforts to assist DataFocus in the collection of the accounts receivable of the
Business outstanding as of the Closing Date.

            (b) From and after the Closing Date, DataFocus shall promptly

contract programming or other services under any Contracts, including any
thereof the assignment of which to CIBER shall not have been fully accomplished
at Closing. CIBER will promptly forward to DataFocus any collections of revenues
CIBER receives that are derived from DataFocus' performance through the Closing
Date.

            (c) The parties agree to prorate, as of the close of business on the
Closing Date, the expenses of the Business of the type identified on Exhibit F
attached hereto. Any adjustment pursuant to this subparagraph shall be agreed
upon and shall be payable within sixty (60) days after the Closing Date;
provided, however, that if the amount of a proratable item is not known as of
such date, the parties shall prorate such item based on the prior year's
assessment or another reasonable basis and shall then adjust such proration when
the actual amount becomes known. The parties agree to negotiate in good faith
adjustments for any other items that arise following the Closing Date.

            (d) DataFocus shall furnish to CIBER at Closing, to the extent
information is then available and as soon as practicable after Closing if not
then available, a list of all commissions, bonuses and other payments that may
become payable by DataFocus after Closing to employees or independent
contractors of DataFocus providing services to the Business. The party receiving
the revenues in respect of which such commissions or bonuses are payable shall
be responsible for accruing and paying, when due, such commissions and bonuses
to the employees and independent contractors entitled to receive such amounts.
To the extent both DataFocus and CIBER receive such revenues, the responsibility
for the payment of the commissions and bonuses attributable thereto shall be
allocated between them proportionately.

KTI nor DataFocus has received any written communication that alleges, or is
aware of any pending allegation, that the Business is in violation of applicable
Environmental Laws;

                  (iii) Except as set forth on Schedule 7(n), to the best of
each of KTI's and DataFocus' knowledge, there are no releases of Material of
Environmental Concern that could form the basis of any claim against KTI,
DataFocus or the Business in relation to the Business;

           (o) Financial Statements. Schedule 7(o) attached hereto contains
unaudited balance sheets of DataFocus as of December 31, 1995 and as of March
31, 1996 and unaudited related statements of income of DataFocus for the period
January 1, 1995 to December 31, 1995 and for the period January 1, 1996 to March

Financial Statements are subject in each case to normal year-end adjustments and
any other adjustments described therein. Each of the DataFocus Financial
Statements has been prepared in accordance with generally accepted accounting
principles consistently applied during the periods involved, except as otherwise
noted therein and except that the DataFocus Financial Statements do not contain
all of the footnote disclosures required by generally accepted accounting
principles. The statement of operations for DataFocus for the three months ended
March 31, 1996 and the other financial information delivered to CIBER fairly
present the financial position of DataFocus. Also attached as Schedule 7(o)
hereto is the profit and loss statement of the Business for the period January
1, 1996 to May 31, 1996. Such profit and loss statement was prepared in
accordance with the normal internal accounting procedures and policies;

            (p) Labor Relations.

                  (i) Except as set forth on Schedule 7(p) attached hereto,
neither KTI nor DataFocus is a party to or bound by any collective bargaining or
other labor agreement which relates to the operations of the Business. Except as
set forth on Schedule 7(p), no employees of DataFocus employed in the Business
are represented by any labor organization, and, as of the date hereof, no labor
organization or group of employees of DataFocus employed in the Business has
made a demand for recognition, has filed a petition seeking a representation
proceeding or given DataFocus notice of any intention to hold an election of a
collective bargaining representative and no strike, work stoppage or labor
disturbance exists or, to each of KTI's and DataFocus' knowledge, is threatened
which involves any employees of DataFocus employed in the Business;

                  (ii) Except as set forth on Schedule 7(p) attached hereto,
there are no pending complaints or charges or, to each of KTI's and DataFocus'
knowledge, threatened complaints or charges against KTI or DataFocus with
respect to any employee or group of employees of DataFocus employed in the
Business or filed or pending with any federal, state or local governmental
authority or court alleging employment discrimination by KTI or DataFocus with
respect to any employee or group of employees of DataFocus employed in the
Business;

            (q) No Undisclosed Liabilities. Except as and to the extent set
forth on Schedule 7(q) attached hereto and on the balance sheets included in the
DataFocus Financial Statements, DataFocus does not have any liabilities or
obligations of any nature, whether or not accrued, contingent or otherwise, that
could have a Material Adverse Effect on the Business;

            (r) Personnel Compensation. At or prior to Closing, all DataFocus
personnel providing services for the Business have been or will have been fully
paid for such services through July 15, 1996 and amounts payable for services
between July 15, 1996 and the Closing Date will be paid by DataFocus pursuant to
the adjustment to the purchase price of the Assets in accordance with Sections 3
and 6 hereof;

            (s) Employees. Schedule 7(s) attached hereto identifies all
employees, independent contractors and other personnel of DataFocus who provide
services for the Business, their respective rates of pay at the date hereof, and
with respect to all billing consultants (employees or independent contractors),

structure, the purchase order number under which such consultant is currently
working and the date on which such purchase order is scheduled to be completed.
Each of DataFocus' personnel identified on Schedule 7(s) is working full-time
(unless noted as part-time) in the Business. Except as identified on Schedule
7(s), none of such personnel has expressly stated to an officer or manager of
DataFocus that he or she intends to resign or cease working with the Business
within six months after Closing;

            (t) Consultants. DataFocus has no fewer than forty (40) full-time
billing consultants (not less than 25 of whom are employees) under contract in
the Business (i.e., employees or consultants averaging at least thirty (30)
billable hours per week for the two (2) calendar months ended June 30, 1996);

            (u) Accelerated Vesting. Any employee of DataFocus who is offered
employment by CIBER and who has any unvested balance in any DataFocus-sponsored
401(k) plan shall be 100% vested in such plan on or as of the Closing Date; and

            (v) Materiality. The representations and warranties of KTI and
DataFocus contained in this Agreement, disregarding all qualifications and
exceptions contained therein relating to

exceptions as would not in the aggregate have a Material Adverse Effect on the
Business.

all files provided pursuant to paragraph 1(f) are correct and complete in all
material respects. Correct and complete copies of all agreements and instruments
referred to in such Exhibits have been delivered to CIBER.

stockholder action of CIBER, and constitute (or, upon execution and delivery,

of equity;

            (b) No Conflict or Breach. The execution and delivery of this
Agreement, the consummation of the transactions contemplated hereby and the
fulfillment of the terms hereof will not (i) constitute, with or without the
giving of notice or passage or time, or both, a breach of any of the terms or
provisions of, or a default under any indenture, mortgage, deed of trust, loan
agreement or other agreement or instrument to which CIBER is a party or by which
it or its properties may be bound or affected, except any such breach or default

interest, lien or violation would not, individually or in the aggregate, have a
Material Adverse Effect on CIBER;

routine governmental consents, approvals and authorizations) or (ii) by any
agreement or instrument to which CIBER is a party, or by which CIBER or any of
its properties or businesses is bound or affected, is required in order to
permit the consummation of the transactions contemplated by this Agreement
(other than any agreement or instrument involving less than $25,000 in annual
expense or revenue);

            (d) No Legal Conflicts. CIBER is not prohibited by any order, writ,
injunction or decree of any body of competent jurisdiction from consummating the
transactions contemplated by this Agreement, and no action or proceeding is
pending or, to the best of CIBER's knowledge, threatened against CIBER which
questions the validity of this Agreement or any of the actions which the parties
hereto have taken in connection herewith or which it is contemplated they shall
take in connection herewith;
