     Re:   Proposed Combination of Docucon, Inc. & Digital Vision Systems, Inc.
           --------------------------------------------------------------------

Dear Mr. Schwartz:

     This Letter Agreement amends and restates the Letter Agreement dated
March 30, 2001, which proposed the corporate combination of Digital Vision
Systems, Inc., a Texas corporation ("DVS") and Docucon, Inc., a Delaware
corporation ("DOCU") ("DVS" and "DOCU" shall collectively be referred to herein
as the "Parties" and each separately as a "Party"). Upon the review of various
issues, including the financial position of the parties, DVS proposes the
following updated terms and various matters to be provided for in the definitive
merger agreement and plan of reorganization between DVS and DOCU:

1.   CORPORATE REORGANIZATION

     It is intended that DVS and DOCU shall enter into a corporate
combination (the "Public Combination"), whether through a merger, acquisition
or other type of corporate combination, which will be determined at a later
date by which the current shareholders of DVS will obtain shares of common
stock of DOCU, such that the former DVS stockholders shall own 92.5% of DOCU
common stock, par value $.01 per share ("Common Stock"), after receipt of the
financing discussed in paragraph 7 below. In calculating the foregoing
percentage, it is assumed that ownership percentages are determined by
references to fully diluted, as if converted common shares outstanding for
both DOCU and DVS. Through the Public Combination, DVS shall become a
wholly-owned subsidiary of DOCU.

     As a condition, and prior, to the Public Combination, DOCU will adjust
its capitalization to accommodate the agreed upon percentage and provide
adequate shares for future corporate purposes.

     Upon completion of the Public Combination, there shall up to seven
directors divided into three classes. Each director shall serve for three year
terms. The Class 1 directors shall be

up for election at the first annual stockholders meeting after the Public
Combination, the Class 2 directors shall be up for election at the second
annual stockholders meeting after the Public Combination, and the Class 3
director shall be up for election at the third annual stockholders meeting
after the Public Combination. DOCU shall appoint a Class 1 director and a
Class 3 director.

     After the Public Combination, there shall be in effect (i) a directors'
and officers' liability insurance policy with at least substantially the same
coverage which DOCU currently provides and (ii) directors' and officers'
liability tail insurance policy with respect to claims arising from facts or
events which occurred on or before the Public Combination.

     For agreeing to continue as a director after the Public Combination and
for prior compensation to DOCU, Robert Schwartz shall receive 0.5% of the total
Common Stock post-merger out of the Common Stock percentage to be retained by
DOCU's shareholders.

     All costs associated with the Public Combination will be advanced by
DVS, including but not limited to the legal fees and filing fees associated with
the preparation of the definitive merger agreement and plan of reorganization,
the regulatory filings and the administration of the Special Meeting of
Shareholders. Any amount that was advanced by DVS under this provision will be
credited towards the DVS' capital requirement under Section 7 below.

2.   DUE DILIGENCE

     a)  From the date hereof, each Party will make available to the other
Party for review their respective financial statements, books, records,
corporate documents and other information as the other Party may reasonably
request, and each party shall have the opportunity to meet with attorneys,
accountants and key personnel of the other Party to discuss the financial and
business conditions of the respective party and to make whatever future
independent investigation deemed necessary and prudent. The Parties agree to
cooperate with each other in complying with these requests and providing such
materials as the other party may request.

     b)  Each party shall make appropriate representations in a definitive
merger agreement ("Merger Agreement") that it has fully and independently
satisfied itself on all aspects of the other Party's business, including but not
limited to financial statements, books and records.

     c)  Each party shall represent and agree that all confidential
information which each Party or any of its officers, employees, agents,
consultants, or representatives, may possess or may receive in the future
pertaining to the financial or other condition of the other Party, shall not be
disclosed or made available to any other person or entity other than current
members of the Board of Directors, officers, employees, agents, consultants, or
representatives at any time without the express written consent of the other
Party.
