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

         This Employment Agreement (the "Agreement") is dated as of October 23,
1998, between BancTec, Inc., a Delaware corporation with its principal executive
offices at 4851 LBJ Freeway, Dallas, Texas 75244 (the "Company"), and Kevin L.
Roper (the "Employee") who resides at 120 Dickens Drive, Coppell, Texas 75019.


                              W I T N E S S E T H:


    WHEREAS, the Employee and the Company desire to define the terms of the
employment of the Employee with the Company;


         NOW, THEREFORE, for and in consideration of the premises and the mutual
covenants contained herein, and for other good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged, and subject to the
terms and conditions hereinafter set forth, the parties hereto agree as follows:


1.       DEFINITIONS.
         -----------

         In addition to the words and terms elsewhere defined in this Agreement,
the following words and terms as used herein shall have the following meanings,
unless the context or use indicates a different meaning:

                  "Cause" means (a) any act by the Employee that is materially
         adverse to the best interests of the Company and which, if the subject
         of a criminal proceeding, could result in a criminal conviction for a
         felony or (b) the failure by the Employee to substantially perform his
         duties hereunder, which duties are within the control of the Employee
         (other than the failure resulting from the Employee's incapacity due to
         physical or mental illness), provided, however, that the Employee shall
         not be deemed to be terminated for Cause under this subsection (b)
         unless and until (1) after the Employee receives written notice from
         the Company specifying with reasonable particularity the actions of
         Employee which constitute a violation of this subsection (b) and (2)
         within a period of 30 days after receipt of such notice (and during
         which the violation is within the control of the Employee), Employee
         fails to reasonably and prospectively cure such violation.

                  "Good Reason" means the occurrence of a Triggering Event (as
         defined below) and (A) without his prior concurrence, the Employee is
         assigned any duties or responsibilities that are inconsistent with his
         position, duties, responsibilities or status at the commencement of the
         term of this Agreement, or his reporting responsibilities or titles in
         effect at such time are changed, (B) the Employee's total compensation
         is reduced or any other failure by the Company to comply with Section 4
         hereof, (C) any change in any employee benefit plans or arrangements in
         effect on the date hereof in which the Employee participates (including
         without limitation any pension and retirement plan, savings and profit
         sharing plan, stock ownership or purchase plan, stock option 

<PAGE>
 
         plan, or life, medical or disability insurance plan), which would
         adversely affect the Employee's rights or benefits thereunder, unless
         such change occurs pursuant to a program applicable to all executive
         officers of the Company and does not result in a proportionately
         greater reduction in the rights of or benefits to the Employee as
         compared to any other executive officer of the Company, or (D) without
         his prior concurrence, the Employee is required to engage in an
         increased amount of travel on the Company's business.

                  "Triggering Date" means the date of a Triggering Event.

                  "Triggering Event" means an event of a nature that would be
         required to be reported by the Company in response to Item 6(d) of
         Schedule 14A of Regulation 14A promulgated under the Exchange Act;
         provided that, without limitation, such an event shall be deemed to
         have occurred if (a) any person or group (as such terms are used in
         Section 13(d) and 14(d) of the Exchange Act) is or becomes the
         beneficial owner (as defined in Rule 13d-3 under the Exchange Act),
         directly or indirectly, of securities of the Company representing more
         than 20% of the combined voting power of the Company's then outstanding
         securities, or (b) there are serving as directors two or more persons
         who were elected as members of the Board of Directors and were not
         nominated by management or the Board of Directors of the Company to
         serve on the Board of Directors of the Company, or (c) the Company is
         merged or consolidated with another corporation and as a result of such
         merger or consolidation less than 51% of the outstanding voting
         securities of the surviving or resulting corporation are owned in the
         aggregate by the former shareholders of the Company, excluding for
         purposes of such calculation shares of the voting securities of the
         Company owned by a party to such merger or consolidation or affiliates
         (within the meaning of the Exchange Act) of such party, as the same
         existed immediately prior to such merger or consolidation, or (d) the
         Company sells all or substantially all of its assets to another
         corporation which is not a wholly-owned subsidiary of the Company.

2.       EMPLOYMENT.
         ----------

         The Company hereby employs the Employee and the Employee hereby accepts
employment on the terms and conditions set forth herein.

3.       TERM.
         ----

         Subject to the provisions of termination as provided in Section 9 of
this Agreement, the term of the Employee's employment with the Company shall
commence on the date hereof and shall terminate on October 23, 2003, unless
sooner terminated as provided for herein.

4.       SALARY.
         ------

         (a) For all services rendered by the Employee under this Agreement, the
Company shall pay the Employee a base salary as established each year by the
Board of Directors, payable in accordance with the Company's customary payroll
practices, with merit increases as may, in the sole discretion of the Board of
Directors of the Company, be approved from time to time by the Board of
Directors of the Company.

         (b) The Employee shall be entitled to participate in or receive
benefits under any employee benefit or bonus plan or arrangement (collectively
referred to as "Benefits") made available by the Company in the future to its
executive officers and key management personnel, subject to and on a basis
consistent with the terms, conditions and overall administration of such plan or
arrangement. Nothing paid to the Employee under any plan or arrangement
presently in effect or made available in the future shall be deemed to be in
lieu of the salary payable to the Employee pursuant to Subsection 4(a).


                                       2
<PAGE>
 
5.       DUTIES.
         ------

         The Employee shall continue to be engaged in a managerial capacity with
the Company to supervise and direct the activities and to maintain the public
relations and goodwill of the Company. The precise services of the Employee may
be extended or curtailed from time to time at the direction of the Board of
Directors of the Company.

6.       EXTENT OF SERVICES AND SITUS.
         ----------------------------

         The Employee shall devote such time, attention, and energy to the
business and affairs of the Company as are necessary to the performance and
discharge of the duties assigned to Employee under this Agreement. Employee
shall not during the term of his employment under this Agreement engage in any
other business activity that could constitute a conflict of interest, whether or
not such business activity is pursued for gain, profit, or other pecuniary
advantage. This shall not be construed as preventing the Employee from managing
his current investments or investing his assets in such form or manner as will
not require any services on the part of the Employee in the operation and the
affairs of the companies in which such investments are made. On or after the
Triggering Date, the Employee shall not be required to change the situs of his
employment from his permanent place of employment immediately prior to the
Triggering Date.

7.       DISABILITY.
         ----------

         If the Employee is unable to perform his services by reason of illness
or incapacity for a continuous period in excess of six months, unless otherwise
required by the provisions of Sections 10 or 25 of this Agreement, compensation
otherwise payable by the Company shall cease and any future payments to the
Employee shall be subject to the terms and provisions of long-term disability
insurance coverage, if any, maintained by the Company. Notwithstanding anything
herein to the contrary, the Board of Directors of the Company may terminate the
Employee's employment with the Company under this Agreement at any time after
the Employee shall be absent from his employment, for whatever reason, for a
continuous period of more than six months, and, except for any obligations of
the Company under Sections 10, 23, and 26 of this Agreement, all other
obligations of the Company hereunder shall cease upon such termination.

8.       COMPENSATION AFTER DEATH.
         ------------------------

         If the Employee dies during the term of his employment, the Company
shall pay to such person as the Employee shall designate in a notice filed with
the Company, or, if no such person shall be designated, to his estate as a lump
sum death benefit, his base salary which would otherwise be payable to the
Employee at the time of his death, in equal semi-monthly installments on the
first and fifteenth day of each and every month, for a period of months (not
exceeding 12) determined by multiplying two times the number of complete
12-month periods of employment of the Employee commencing from the date of such
employment by the Company, in addition to any payments the Employee's spouse,
beneficiaries, or estate may be entitled to receive pursuant to any pension or
employee benefit plan or life insurance policy which may be maintained by the
Company, and such payments shall fully discharge the Company's obligations
hereunder.

9.       TERMINATION.
         -----------

         9.1      Termination Prior to the Triggering Date.
                  ----------------------------------------  

                  (a) Upon 30 days' prior written notice to the Employee and
         prior to the Triggering Date,

                                       3
<PAGE>
 
        the Company may terminate the Employee's employment with the Company
        under this Agreement with or without Cause and by the affirmative vote
        of two-thirds of the members of the Board of Directors of the Company.

            (b) Prior to the Triggering Date, the Employee may terminate his
        employment with the Company under this Agreement by giving 30 days'
        prior written notice of his desire to the Board of Directors of the
        Company and receiving an affirmative vote of two-thirds of the members
        of the Board of Directors of the Company. The Employee will continue to
        receive his Base Salary and Benefits through the date of termination
        with no liability on the part of the Company for further payments to the
        Employee unless Employee terminates his employment pursuant to Section
        9.1(c)(ii), at which time Sections 9.1(c) and (d) shall apply.

            (c) In the event that (i) the Company terminates the Employee's
        employment for any reason other than for Cause and at a time when
        Employee is not eligible to receive benefits under the Company's Long
        Term Disability Plan; or (ii) the Employee terminates his employment as
        a result of any of the following reasons: (A) without the Employee's
        consent the Company materially diminishes the scope of the Employee's
        duties, assigns to the Employee duties materially inconsistent with his
        designated position, or reduces the Employee's Base Salary or Targeted
        Bonus to an amount less than previously determined or established by the
        Board of Directors, or (B) the Company breached any of its material
        obligations under this Agreement and such breach is not cured within 30
        days after written notice thereof by the Employee; then the Company
        shall pay the Employee severance payments in an amount equal to the sum
        of the (x) Employee's annualized Base Salary in effect at the time of
        such termination, and (y) an amount equal to the Employee's Targeted
        Bonus for the fiscal year in which such termination occurs (provided,
        however, that if the basis for Employee's termination is the reduction
        in his Base Salary or the reduction of his Targeted Bonus, the severance
        pay shall be based on the Base Salary and the Targeted Bonus in effect
        prior to such reduction). The severance payments shall be made in
        installments over a period of 12 months. Notwithstanding the foregoing,
        if the Employee terminates his employment pursuant to clause (ii) above,
        he shall be entitled to the severance payments provided for in this
        paragraph only if he gives written notice to the Company of his
        termination of employment within 30 days after the occurrence of the
        event or events specified in clause (ii) on which he bases his
        termination and such notice specifies such event or events.

            (d) The severance payments provided for in this Section 9.1 shall be
        in lieu of all severance payments or benefits to which the Employee
        might otherwise be entitled under Company severance policies from time
        to time in effect, except for (i) accrued and unpaid Base Salary to the
        date of termination, and (ii) any bonus due with respect to fiscal years
        completed as of the date of termination pursuant to the Executive Bonus
        Plan. Nothing contained in the foregoing shall be construed so as to
        affect the Employee's rights or the Company's obligations relating to
        agreements or benefits that are unrelated to termination of employment.

            (e) In the event that the Company terminates the employee's
        employment for Cause, the Company will have no liability on its part for
        further payments after the termination date to the Employee.

            (f) In voting upon such termination described in Subsections 9.1(a)
        or (b), if the Employee is also a member of the Board of Directors of
        the Company, then he may not vote on such termination, and the total
        number of members of the Board of Directors will be reduced by one for
        purposes of voting on such termination.

         9.2      Termination After the Triggering Date.
                  -------------------------------------

                  (a) On or after the Triggering Date and irrespective of
         whether or not the Employee has given notice of termination of
         employment pursuant to Section 9.2(c), the Company may terminate the
         Employee's employment with the Company under this Agreement only for
         Cause and, subject to the provisions of Sections 23 and 26 hereof, with
         no liability on its part for further payments to the Employee by the
         affirmative vote of two-thirds of the members of the Board of Directors
         of the Company. In voting upon such termination, if the Employee is
         also a member of the Board of Directors of the Company, then he may not
         vote on such termination, and the total number of members of the Board
         of Directors will be reduced by one for purposes of voting on such
         termination.

                  (b) On or after the Triggering Date and irrespective of
         whether or not the Employee has given notice of termination of
         employment pursuant to Section 9.2(c), if the Employee's employment
         with the Company is terminated without Cause or if Employee terminates
         his employment with the Company for Good Reason, the Employee will
         continue to accrue and receive his base salary and Benefits through the
         date of termination and will be entitled to receive the benefits
         provided for under Section 10 hereof.

                  (c) On or after the Triggering Date, the Employee may, in his
         sole and absolute discretion and without any prior approval by the
         Board of Directors of the Company, and upon 12 months' prior written
         notice to the Company, terminate his employment with the Company under
         this Agreement for any reason whatsoever. If the Employee's employment
         with the Company under this Agreement is terminated pursuant to this
         Subsection 9.2(c) and subject in all respects to the provisions of
         Section 9.2(a) and (b), the Employee will continue to accrue and
         receive his base salary and Benefits through the date of termination
         and will be entitled to receive the benefits provided for under Section
         10 hereof. No termination of the Employee's employment with the Company
         pursuant to Subsections 9.2(b) or (c) shall in any way terminate the
         Company's obligations under Sections 23 and 26 of this Agreement.

10.      COMPENSATION AFTER CERTAIN TERMINATIONS.
         --------------------------------------- 

         If the Employee's employment with the Company is terminated (whether
such termination is by the Employee or by the Company) at any time on or within
three years after the Triggering Date for any reason other than (a) termination
by the Company for Cause, (b) the Employee having reached the age of 65, or (c)
the Employee's death, then, within five days after the date of such termination,
the Company shall pay the Employee a lump sum amount in cash equal to 2 times
the Employee's annualized includable compensation (within the meaning of Section
280G(d)(1) of the Internal Revenue Code of 1986, as amended) from the Company
during the period consisting of the five full taxable years of the Employee
ending immediately prior to the year in which the Triggering Date occurred (or
such portion of such period during which the Employee was an employee of the
Company).

11.      TRANSFER OF ASSETS TO IRREVOCABLE TRUST.
         ---------------------------------------

         On the Triggering Date or as soon thereafter as the Company knows of
the occurrence of a Triggering Event, the Company shall transfer cash to the
Irrevocable Trust created by the Irrevocable Trust Agreement, an executed copy
of which is attached hereto as Exhibit A, in an amount no less than the total
amount which would be payable to the Employee pursuant to Section 10 of this
Agreement as if the Employee's employment terminated on the Triggering Date. The
Company shall take whatever steps are necessary to maintain the trust
established pursuant to the Irrevocable Trust Agreement and shall comply with
the terms of the Irrevocable Trust Agreement both before and after the
Triggering Date and until the Irrevocable Trust terminates by its own terms.

12.      MITIGATION.
         ----------

         The Employee shall not be required to mitigate the amount of any
payment provided for in this Agreement by seeking other employment or otherwise,
nor shall the amount of any payment provided for in this Agreement be reduced by
any compensation earned by the Employee as the result of employment by another
employer after the date of termination of Employee's employment with the
Company, or otherwise.

13.      ENTIRE AGREEMENT.
         ----------------

         This Agreement embodies the entire agreement and understanding between
the parties hereto with respect to the subject matter hereof and supersedes all
prior negotiations, agreements, and understandings relating to such subject
matter, and may be modified or amended only by an instrument in writing signed
by the parties hereto.

Trust as provided in Section 11, the Company shall be permitted to assign this
Agreement to any corporation or other business entity succeeding to
substantially all of the business and assets of the Company by merger,
consolidation, sale of assets, or otherwise, but only if by written agreement
the Company's successor assumes in full all of the Company's obligations under
this Agreement. From and after assignment of this Agreement by the Company in
accordance with the foregoing provisions, a Triggering Event shall be deemed to
have occurred. Failure by the Company to obtain such assumption prior to the
effectiveness of such succession shall be a breach of this Agreement and shall
entitle the Employee to immediately receive compensation under this Agreement
from the Company and from the Company's successor in the same aggregate amount
and on the same terms as he would be entitled to hereunder if he had voluntarily
terminated his employment with the Company for Good Reason after the Triggering
Date, and, for purposes of implementing the foregoing, the date on which any
such succession becomes effective shall be deemed the Triggering Date.
