Gentlemen:

               You have advised Chase Securities Inc. ("CSI") and Chase Bank of
                                                        ---                    
Texas, N.A. ("Chase") that you, together with your affiliates (collectively,
              -----                                                         
"WCAS"), will form a new corporation ("Newco") for the purposes of effecting a
 ----                                  -----                                  
recapitalization (the "Acquisition") of BancTec, Inc. ("BancTec"). The
                       -----------                      -------        
Acquisition will be effected by merging Newco with and into BancTec, with
BancTec continuing as the surviving corporation (the "Surviving Corporation"). A
                                                      ---------------------     
payment of cash consideration will be made for a specified proportion of the
outstanding common stock of BancTec (the "Electing Shares"), while the remaining
                                          ---------------                       
outstanding common stock of BancTec will remain outstanding (the "Retained
                                                                  --------
Shares") as shares of the Surviving Corporation. As a result of the Acquisition,
- ------                                                              
each Electing Share will be converted into the cash consideration per share, the
Retained Shares will remain outstanding as shares of common stock of the
Surviving Corporation, and the outstanding shares of Newco will be converted
into approximately 93.5% (expressed as a percentage of the Surviving Corporation
following the Acquisition) of the outstanding common stock of the Surviving
Corporation. Alternatively, if able to be accounted for as a recapitalization,
WCAS and one or more other investors (collectively, the "Other Investor") will

6.5% of Newco and merging Newco with and into BancTec, as a result of which WCAS
will become the owner of approximately 93.5% of the common stock of the

 
                                                                               2




Surviving Corporation, the Other Investor will become the owner of approximately
6.5% of such common stock (the "Alternative Acquisition"), and the existing 
                                -----------------------
stockholders of BancTec will receive cash consideration in exchange for all of
their common stock in BancTec. Immediately after the Acquisition, BancTec USA, 
Inc. will merge with or be liquidated into (the "Subsidiary Merger") the
                                                 -----------------
Surviving Corporation (after giving effect to the Subsidiary Merger, the
"Borrower"). In connection with the Acquisition and the Subsidiary Merger,
 --------                                               
approximately $6,300,000 of the existing indebtedness of BancTec will be
refinanced (the "Refinancing"; together with the Acquisition and the Subsidiary
                 -----------

Facility"), (ii) senior subordinated financing in an aggregate amount of
- --------                                                                
$160,000,000 of the Borrower on terms and conditions acceptable to the Agent (as

subsidiaries, including the making of acquisitions and investments in other
entities subject to restrictions and limitations to be determined.

          CSI is pleased to advise you that it is willing to act as sole and

"Administrative Agent"). In addition, Chase is pleased to advise you that it is
 --------------------

"Agent").  Furthermore, Chase is pleased to advise you of its commitment to
 -----                                                                     
provide up to $125,000,000 of the Facilities, upon the terms and subject to the
conditions set forth or referred to in this commitment letter (the "Commitment
                                                                    ----------
Letter") and in the Summary of Terms and Conditions attached hereto as Exhibit A
- ------                                                                          
(the "Term Sheet").
      ----------   

          It is agreed that CSI will act as the Arranger and that Chase will act
as the Administrative Agent and Syndication Agent for the Facilities. You agree
that no other agents, co-agents, arrangers or managers will be appointed, no
other titles will be awarded and no compensation will be paid in connection with
the Facilities unless you and CSI and Chase shall so agree (with CSI and Chase
to reasonably consider any requests by you).

          CSI and Chase intend to syndicate the Facilities to a group of
financial institutions (together with Chase, the "Lenders") identified by CSI
                                                  -------                    
and Chase in consultation with you. CSI and Chase intend to commence syndication
efforts promptly upon your entering into definitive documentation with respect
to the Acquisition, and you agree actively to assist CSI and Chase in completing
a syndication satisfactory to them. Such assistance shall include (a) your using
commercially reasonable efforts to ensure that the syndication efforts benefit
materially from the

 
                                                                               3

existing lending relationships of WCAS and BancTec, (b) direct contact between
senior management and advisors of WCAS, BancTec and the Borrower and the
proposed Lenders, (c) assistance in the preparation of a Confidential
Information Memorandum and other marketing materials to be used in connection
with the syndication and (d) the hosting, with CSI and Chase, of one or more
meetings of prospective Lenders.

          CSI and Chase will manage all aspects of the syndication of the
Facilities, including decisions as to the selection of institutions to be
approached and when they will be approached, when their commitments will be
accepted, which institutions will participate, the allocations of the
commitments among the Lenders and the amount and distribution of fees among the
Lenders in consultation with you. To assist CSI and Chase in their syndication
efforts, you agree promptly to prepare and provide to CSI and Chase all
information with respect to WCAS, the Borrower, the Transactions and the other
transactions contemplated hereby and to obtain the agreement of BancTec to
prepare and provide all information with respect to it, in each case, including
all reasonable financial information and projections (the "Projections"), as we
                                                           -----------         
may reasonably request in connection with the arrangement and syndication of the
Facilities. You hereby represent and covenant that, to your knowledge, (a) all
information other than the Projections (the "Information") that has been or will
                                             -----------

will be, when furnished, complete and correct in all material respects and does
not or will not, when furnished, contain any untrue statement of a material fact
or omit to state a material fact necessary in order to make the statements
contained therein not materially misleading in light of the circumstances under
which such statements are made and (b) the Projections that have been or will be
made available to CSI and Chase by you or any of your representatives have been
or will be prepared in good faith based upon assumptions that you believe in
good faith to be reasonable. CSI and Chase understand that BancTec is not your
representative. You understand that in arranging and syndicating the Facilities
we may use and rely on the Information and Projections without independent
verification thereof.

          As consideration for the commitments of Chase hereunder and the
agreements of the Agent to perform the services described herein, you agree to
pay, and to cause the Borrower to pay, the nonrefundable fees set forth in Annex
I to the Term Sheet and in the Fee Letter, dated the date hereof and delivered
herewith (the "Fee Letter").
               ----------   

          CSI and Chase shall be entitled, after consultation with you, to
change the pricing, terms, structure or amounts of any of the Facilities if the
syndication has not been completed and if CSI and Chase reasonably determine
that such changes are advisable to ensure a successful syndication of the
Facilities; provided that (a) the total amount of the Facilities shall remain
unchanged, (b) the interest rate margins and letter of credit fees respectively
applicable to the Facilities shall not be increased by more than 0.75% per annum
and (c) the Term Facility (as defined in the Term Sheet) shall not be revised to
include a "Tranche B" term loan facility of more than $40,000,000. Chase's
commitment hereunder is subject to the agreements in this paragraph.

described herein are subject to (a) there not occurring or becoming known to us

(financial or otherwise) or prospects of BancTec and its subsidiaries, taken as
a whole since December 31, 1998, (b) our not becoming aware after the date
hereof of any information or other matter affecting BancTec, the Borrower or the
transactions contemplated hereby which is inconsistent in a material and adverse
manner with any such information or other matter disclosed to us prior to the
date hereof, (c) there not having occurred a material disruption of or material
adverse change in financial, banking or capital market conditions that, in the
judgment of CSI and Chase, could materially impair the syndication of credit
facilities similar or comparable to the Facilities, (d) our satisfaction that
prior to and during the syndication of the Facilities there shall be no
competing offering, placement or arrangement of any debt securities or bank
financing by or on behalf of WCAS, BancTec or the Borrower or any of their
respective affiliates (except for any such debt securities as contemplated
hereby and for any debt securities or bank financing by or on behalf of WCAS and
its other affiliates as are reasonably coordinated with the syndication of the
Facilities in consultation with CSI and Chase), (e) the negotiation, execution
and delivery of definitive documentation with respect to the Facilities
satisfactory to CSI, Chase and their respective counsels, and the closing of the
transactions thereunder and the Transactions on or before September 15, 1999,

          You agree (a) to indemnify and hold harmless CSI, Chase and their
respective affiliates and their respective officers, directors, employees,

may become subject arising out of or in connection with this Commitment Letter,

related transaction or any claim, litigation, investigation or proceeding
relating to any of the foregoing, regardless of whether any indemnified person
is a party thereto, and to reimburse each indemnified person upon demand for any
reasonable legal or other expenses incurred in connection with investigating or
defending any of the foregoing, provided that the foregoing indemnity will not,
                                --------                                       
as to any indemnified person, apply to losses, claims, damages, liabilities or
related expenses to the extent they are found by a final, non-appealable
judgment of a court to arise from the willful misconduct or gross negligence of
such indemnified person, and (b) to reimburse CSI, Chase and their respective
affiliates on demand for all reasonable out-of-pocket expenses (including due
diligence expenses, syndication expenses, consultant's fees and expenses, travel
expenses, and reasonable fees, charges and disbursements of counsel) incurred in

No indemnified person shall be liable for any damages arising from the use by
others of Information (provided that such indemnified person is not in breach of

Facilities.

          You acknowledge that we and our respective affiliates (the term "we"

affiliates) may be providing debt financing, equity capital or other services
(including financial advisory services) to other companies in respect of which
you may have conflicting interests regarding the transactions described herein
and otherwise. We will not use confidential information obtained from you by

 
                                                                               5

virtue of the transactions contemplated by this Commitment Letter or our other
relationships with you in connection with the performance by us of services for
other companies, and we will not furnish any such information to other
companies. You also acknowledge that we have no obligation to use in connection
with the transactions contemplated by this Commitment Letter, or to furnish to
you, confidential information obtained from other companies.

          This Commitment Letter shall not be assignable by any party hereto
(other than an assignment by you to the Surviving Corporation) without the prior
written consent of the other parties hereto (and any purported assignment
without such consent shall be null and void), is intended to be solely for the
benefit of the parties hereto and is not intended to confer any benefits upon,
or create any rights in favor of, any person other than the parties hereto. This
Commitment Letter may not be amended or waived except by an instrument in
writing signed by you, CSI and Chase. This Commitment Letter may be executed in
any number of counterparts, each of which shall be an original, and all of
which, when taken together, shall constitute one agreement. Delivery of an
executed signature page of this Commitment Letter by facsimile transmission
shall be effective as delivery of a manually executed counterpart hereof. This
Commitment Letter and the Fee Letter are the only agreements that have been
entered into among us with respect to the Facilities and set forth the entire
understanding of the parties with respect thereto. This Commitment Letter shall
be governed by, and construed in accordance with, the laws of the State of New
York.

          This Commitment Letter is delivered to you on the understanding that
neither this Commitment Letter, the Term Sheet or the Fee Letter nor any of
their terms or substance shall be disclosed, directly or indirectly, to any
other person except (a) you may disclose this Commitment Letter, the Term Sheet
and the Fee Letter (i) to your officers, agents and advisors who are directly
involved in the consideration of this matter or (ii) as may be compelled in a
judicial or administrative proceeding or as otherwise required by law, including
public disclosures required under United States securities rules and regulations
(in which case you agree to inform us promptly thereof) and (b) you may disclose
this Commitment Letter and the Term Sheet, and their terms and substance (but
not the Fee Letter or their terms and substance) to BancTec, its officers,
agents and advisors who are directly involved in the consideration of the
Transactions on a confidential basis.

          The compensation, reimbursement, indemnification and confidentiality
provisions contained herein and in the Fee Letter shall remain in full force and
effect regardless of whether definitive financing documentation shall be
executed and delivered and notwithstanding the termination of this Commitment
Letter or the commitments hereunder; provided, that your obligations under this
                                     --------                                  
Commitment Letter, other than those arising under the fourth, fifth, sixth and
thirteenth paragraphs hereof, shall automatically terminate and be superseded by
the provisions of the definitive documentation relating to the Facilities upon
the initial funding thereunder, and you shall automatically be released from all
liability in connection therewith at such time. Subject to the foregoing, this
Commitment Letter shall automatically terminate if the closing of the Facilities
shall not occur by reason of any condition described in clause (c) or (d) in the
ninth paragraph hereof not being satisfied or waived, as of the date on which
the parties hereto mutually agree that such closing would otherwise occur.

 
                                                                               6

your acceptance of the terms hereof and of the Term Sheet and the Fee Letter by
returning to us executed counterparts hereof and of the Fee Letter not later
than 5:00 p.m., New York City time, on Wednesday, April 7, 1999. The commitments
and the agreements herein will expire at such time in the event Chase has not

immediately preceding sentence.

connection with this important financing.

                       2% above the rate applicable to ABR Loans.

Rate and Fee Basis:    All per annum rates shall be calculated on the basis of a
                       year of 360 days (or 365/366 days, in the case of ABR
                       Loans the interest rate payable on which is then based on
