                          SECOND SUPPLEMENTAL INDENTURE

     THIS SECOND SUPPLEMENTAL INDENTURE (the "Second Supplemental Indenture") is
made as of the 30th day of July, 2002, between Xerox Corporation, a New York
corporation (the "Issuer"), the persons named as Guarantors on the signature
pages hereto (collectively, the "Guarantors"), and Wells Fargo Bank Minnesota,
National Association, as trustee (the "Trustee").

    WHEREAS, the Issuer and the Trustee heretofore executed and delivered an
Indenture, dated as of January 17, 2002, that was supplemented by the First
Supplemental Indenture, dated as of June 21, 2002, among the Issuer, the
Guarantors and the Trustee (as supplemented, the "Indenture"); and

    WHEREAS, pursuant to the Indenture, the Issuer issued and the Trustee
authenticated and delivered EUR 225 million aggregate principal amount of the
Issuer's 9 3/4% Senior Notes due 2009 (the "Senior Notes"); and

    WHEREAS, the Indenture contains the following two defects (together, the
"Defects"): (i) the definition of "Domestic Insignificant Subsidiary" in Section
101 of the Indenture contains an incorrect cross-reference to Section 1013(b) of
the Indenture and the correct cross-reference is to Section 1013(a)(2) of the
Indenture, and (ii) the proviso in the definition of "Specified Subsidiary" in
Section 101 contains a defect in that it uses the term "corporation" instead of
"Subsidiary"; and

    WHEREAS, the Issuer wishes to reform the Indenture to cure the Defects,
without the consent of the Holders of the Senior Notes, pursuant to Section
901(5) of the Indenture; and

    WHEREAS, the Issuer is delivering contemporaneously herewith to the Trustee
(i) a copy of the resolutions of the Board of Directors of the Issuer and the
Board of Directors/Managers of each of the Guarantors authorizing the execution,
delivery and performance of this Second Supplemental Indenture, and (ii) an
Opinion of Counsel in compliance with and to the effect set forth in Sections
103 and 903 of the Indenture; and

    WHEREAS, the Second Supplemental Indenture complies with and is authorized
by the applicable provisions of the Indenture, including the conditions
precedent set forth in the Indenture to be performed or complied with by the
Issuer relating to the execution and delivery of this Second Supplemental
Indenture.

    NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt of which is hereby acknowledged, the Issuer,
the Guarantors and the Trustee mutually covenant and agree as follows:

                              ARTICLE I
                             DEFINITIONS

    SECTION 1.01.  General.  For all purposes of the Indenture and this
Second Supplemental Indenture, except as otherwise expressly provided or
unless the context otherwise requires:

<PAGE>

    (a) the words "herein", "hereof" and "hereunder" and other words of similar
import refer to the Indenture and this Second Supplemental Indenture as a whole
and not to any particular Article, Section or subdivision; and

    (b) capitalized terms used but not defined herein shall have the meanings
assigned to them in the Indenture.

                                   ARTICLE II
                                  REFORMATIONS

    SECTION 2.01. The defective cross-reference to "Section 1013 (b)" in the
definition of "Domestic Insignificant Subsidiary" in Section 101 of the
Indenture is hereby cured and reformed to "Section 1013(a)(2)" so that such
definition reads in its entirety as follows:

       "Domestic Insignificant Subsidiary" means any Domestic Wholly Owned
    Restricted Subsidiary that is not a Guarantor other than a Person that is
    described in Section 1013(a)(2) hereof."

    SECTION 2.02. The defective term "corporation" in the proviso of the
definition of "Specified Subsidiary" in Section 101 of the Indenture is hereby
cured and reformed to "Subsidiary" so that such definition reads in its entirety
as follows:

       "Specified Subsidiary" means any Subsidiary of the Company from time to
    time having a Consolidated Net Worth Amount of at least $100.0 million;
    provided, however, that each of Xerox Financial Services, Inc., Xerox Credit
    Corporation and any other Subsidiary principally engaged in any business or
    businesses other than development, manufacture and/or marketing of (x)
    business equipment (including, without limitation, reprographic, computer
    (including software) and facsimile equipment), (y) merchandise or (z)
    services (other than financial services) shall be excluded as a "Specified
    Subsidiary" of the Company.

                             ARTICLE III
                            MISCELLANEOUS

    SECTION 3.01. Binding Effect. Upon the execution and delivery of this Second
Supplemental Indenture by the Issuer, the Guarantors and the Trustee, the
Indenture shall be reformed and supplemented in accordance herewith effective as
of January 17, 2002 which is the date of the original Indentures, and this
Second Supplemental Indenture shall form a part of the Indenture for all
purposes, and every Holder of Notes heretofore or hereafter authenticated and
delivered under the Indenture shall be bound thereby.

    SECTION 3.02.  Indenture Remains in Full Force and Effect.  Except as
reformed and supplemented hereby, all provisions in the Indenture shall
remain in full force and effect.

    SECTION 3.03. Indenture and Supplemental Indenture Construed Together. This
Second Supplemental Indenture is an indenture supplementalto and in

as reformed and supplemented by this Supplemental Indenture is in all

<PAGE>

respects confirmed and preserved.

    SECTION 3.05. Conflict with Trust Indenture Act. If any provision of this
Second Supplemental Indenture limits, qualifies or conflicts with any provision
of the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"), that
is required under the Trust Indenture Act to be part of and govern any provision
of this Second Supplemental Indenture, the provision of the Trust Indenture Act
shall control. If any provision of this Second Supplemental Indenture modifies
or excludes any provision of the Trust Indenture Act that may be so modified or
excluded, the provision of the Trust Indenture Act shall be deemed to apply to
the Indenture as so modified or to be excluded by this Second Supplemental
Indenture, as the case may be.

    SECTION 3.06. Severability. In case any provision in this Second
Supplemental Indenture shall be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

    SECTION 3.07. Headings. The Article and Section headings of this Second
Supplemental Indenture have been inserted for convenience of reference only, are
not to be considered a part of this Second Supplemental Indenture and shall in
no way modify or restrict any of the terms or provisions hereof.

    SECTION 3.08. Successors. All agreements of the Issuer and Guarantors in
this Second Supplemental Indenture shall bind their respective successors. All
agreements of the Trustee in this Second Supplemental Indenture shall bind its
successors.

    SECTION 3.09. Governing Law. THIS SECOND SUPPLEMENTAL INDENTURE SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK
BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE
EXTENT THAT THE APPLICATION OF THE LAW OF ANOTHER JURISDICTION WOULD BE REQUIRED
THEREBY.

    SECTION 3.10.  Counterpart Originals.  The parties may sign any number of
copies of this Second Supplemental Indenture.  Each signed copy shall be an
original, but all of them together represent the same agreement.


    IN WITNESS WHEREOF, the parties hereto have caused this Supplemental
Indenture to be duly executed, and attested, as of the date first above written.
