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

Use of Office Space

     Beginning on the Distribution Date, NDC or a subsidiary of NDC ("Occupant")
may continue to occupy a portion of the space currently leased by Global Payment
Systems, LLC ("GPS") in One and Three Concord Gate, Don Mills Ontario Canada
(the "Leased Premises"). The portion of the Leased Premises that shall be used
by Occupant shall consist of approximately 2,000 rentable square feet of space
in the Leased Premises currently associated with NDC's operation of computers
located there. Occupant's use of such space shall be for the purpose of
continuing the operation of computers and providing office space for NDC
personnel involved in the operation and maintenance of such computers. NDC's use
of such space shall commence on the Distribution Date and shall terminate at
midnight on the expiration date of GPS's lease of the Leased Premises (the
"Lease") unless the Lease is terminated earlier in accordance with its terms.

     Occupant's right to occupy a portion of the Leased Premises is expressly
subject to all terms of the Lease. NDC agrees to assume all obligations of GPS,
as "Tenant" under its lease of such space, with respect to the space used by
Occupant under the terms of this Agreement.

     Any act or omission by Occupant that would constitute a default under the
Lease shall, subject to the same notice and cure provisions provided in the
Lease, be deemed a default by NDC under this Exhibit D. In addition, any failure
                                             ---------
by NDC to pay the fees provided for in this Exhibit D when due or any failure by
                                            ---------
NDC to perform any other obligations required under this Exhibit D and the
                                                         ---------
continuance of such failure for five (5) days following notice from GPS to NDC
of such failure, shall be deemed a default under this Exhibit D. Any such
                                                      ---------
default by NDC shall entitle GPS to exercise any and all remedies available to
"Landlord" under the Lease or any other remedies available at law or in equity
under the laws of the Country of Canada, Province of Ontario.

     NDC hereby agrees to indemnify and hold GPS harmless with regard to
Occupant's use of a portion of the Leased Premises as provided herein to the
same extent that GPS is required to indemnify and hold the Landlord harmless
with respect to such space. NDC agrees to obtain and maintain during the period
that Occupant occupies any portion of the Leased Premises pursuant to this
Exhibit D insurance in the same amounts and of the same types (including any
---------
required waiver of subrogation provisions or endorsements) required to be
carried by GPS, as "Tenant" under the Lease, with regard to the Leased Premises.

     Upon the expiration or earlier termination of Occupant's right to occupy a
portion of the Leased Premises pursuant to this Exhibit D, NDC shall return such
                                                ---------
portion of the Leased Premises to GPS in the condition required by the Lease,
normal wear and tear damage by casualty or condemnation excepted.
