                         FIRST AMENDMENT TO 3333 LEASE
                         -----------------------------

     THIS AMENDMENT, made as of the 1st day of November, 1997, between BANK ONE,
ILLINOIS, N.A., not personally but solely as Trustee under Trust Agreement dated
May 23, 1997, and known as Trust No. 11097 ("Landlord") and MAY & SPEH, INC.
("Tenant").

                                   RECITALS

     Landlord and Tenant are parties to a written lease dated June 2, 1997,
("3333 Lease"), for the entire building ("3333 Building") to be constructed at
3333 Finley Road, Downers Grove, Illinois. Section S.4 of the 3333 Lease grants
Tenant certain options to acquire the 3333 Building and the land thereunder;
provided that, Tenant also exercises the option to purchase the building ("1501
Building") commonly referred to as 1501 Opus Place, Downers Grove, Illinois and
the land thereunder pursuant to the option granted in the lease between Landlord
and Tenant also dated June 2, 1997 for the 1501 Building ("1501 Lease").

     The terms and conditions of Tenant's option to purchase the 1501 Building
are set forth in Rider E to the 1501 Lease and the terms and conditions of the
purchase of the 3333 Building are set forth in Rider E to the 3333 Lease. The
purchase price for the 1501 Building is set forth in Rider E to the 1501 Lease
and the purchase price for the 3333 Building is based on a formula which takes
into account the purchase price for the 1501 Building. Landlord and Tenant
desire to increase the purchase price for the 1501 Building and to make a
similar reduction to the purchase price of the 3333 Building to permit Landlord
to refinance the 1501 Building and to finance the construction of the 3333
Building.

     Landlord and Tenant also desire to modify the Base Building Improvements
under the 3333 Lease to include the construction of a tunnel ("Tunnel") from the
3333 Building to the 3333 Building and to modify the Maximum Project Costs to
take into account the change in the Base Building Improvements. In addition
Landlord and Tenant have agreed on the interest rate to be used to determine the
Base Rent and wish to set forth such amount in this amendment.

     Finally, Landlord exchanged a portion of the Land as described in the Lease
located along Finley Road for a like parcel owned by the Village of Downers
Grove and Landlord and Tenant desire to amend the Lease to reflect the change in
the Land.

     NOW, THEREFORE, in consideration of the mutual covenants and conditions
contained herein, the Lease is hereby amended as follows:

     1. All capitalized terms used herein shall have the same meanings as in the
3333 Lease unless otherwise defined herein.

     2. Exhibit A to the 3333 Lease shall be replaced by Exhibit A to this
Amendment.

     3. Notwithstanding anything in the 3333 Lease to the contrary, the Base
Building Improvements shall include the work described on attached Exhibit B.
<PAGE>
 
     4. Notwithstanding anything in the 3333 Lease to the contrary, the Premises
shall include the portion of the Tunnel located on the Land and Tenant's
obligations under this Lease with respect to the Premises, including without
limitation, its obligations to maintain and repair the Premises shall apply to
the portion of the Tunnel included in the Premises.

     5. Rider A to the 3333 Lease shall be replaced with Rider A to this
Amendment.

     6. Section 3.1 of the Purchase Contract attached as Rider E to the 3333
Lease is amended in its entirety to read as follows:

          3.1 PURCHASE PRICE. The purchase price ("Purchase Price") for the
     Property shall be __________________ ___________________
     ($__________________________).

     [The purchase price shall be the product of (i), (ii) and (iii) below, less
     Twelve Million Eight Hundred Thousand Dollars ($12,800,000.00) :

               (i) The Total Project Costs as defined in Rider A to the 3333
     Lease;

               (ii) 1.125 and

               (iii) The lesser of (A) 1.04/N/ (where "N" is the number of years

     increase, if any, in the CPI (as defined in Rider A of the 3333 Lease) from
     January 1, 1997 to the Closing Date.

          Purchaser agrees to pay to Seller and Seller agrees to accept payment
     of the Purchase Price as follows:

               (a) At Closing, Purchaser shall accept title to the Property
     subject to the lien of the First Mortgage (which Purchaser or its nominee
     or designee will take subject to, and with respect to which First Mortgage
     and the loan evidenced and secured thereby Purchaser or its nominee or
     designee shall assume), and the outstanding principal balance thereunder
     shall be credited against the Purchase Price.

               (b) The remaining portion of the Purchase Price, subject to
     prorations and adjustments as provided in Section 8.1, shall be paid on the
     Closing Date by wire transfer of immediately available funds, first to the
     Title Company and then to an account specified by Seller, against delivery
     of instruments of transfer and the other documents specified in Section
     7.1.

     7. Except for the provisions of this Amendment, all the terms, covenants,
and conditions of the Lease and all the rights and obligations of Landlord and
Tenant thereunder, shall remain in full force and effect, and are not otherwise
altered, amended, revised or changed.

<PAGE>
 

       If the annual Base Rent for any period described above cannot be
determined as of the first day of such period, then until such amount is
determined, Tenant shall pay Base Rent at the minimum rate set forth for such
period (or, in the case of the Base Rent as of Commencement Date, assuming the
Fixed Rental Rate was $16.51). When the actual annual Base Rent is determined,
Landlord shall notify Tenant in writing of such amount within thirty (30) days
thereafter and Tenant, in the case of an underpayment, shall pay to Landlord any
additional Base Rent due for the portion of such period prior to the date of
such payment, or Landlord, in the case of an overpayment, shall pay to Tenant
the amount of such overpayment.

       If Tenant exercises its option to extend the Term for an Extended Term,
then within thirty (30) days after receipt of Tenant's notice exercising the
Extension Option (or, if later, eight (8) months prior to the end of the then
Term), Landlord shall notify Tenant of its determination of the Market Rent for
the Extended Term in question. If the Market Rent determined by Landlord is
greater than the Base Rent determined pursuant to clause (2) of paragraphs
(a)(v), (vi) or (vii) above, as the case may be, then within thirty (30) days
after receipt of Landlord's notice of the Market Rent, Tenant shall elect in a
written notice ("Tenant's Rent Determination Notice"), delivered to Landlord
either (i) to accept Landlord's determination of the Market Rent or (ii) to have
the Market Rent determined by appraisal pursuant to paragraph (c) below, in
which event Tenant shall also set forth its determination of the Market Rent. If
Tenant fails to timely deliver such notice, Tenant will be deemed to have
accepted Landlord's determination of the Market Rent.

(b)    As used in this Rider A and in the Lease:

       (i)    "CPI" shall mean the Revised Consumer Price Index for Urban Wage
              Earners and Clerical Workers, All Items (base index year

              published by the United States Department of Labor, Bureau of
              Labor Statistics. If the manner in which the Consumer Price Index
              is determined by the Bureau of Labor Statistics shall be
              substantially revised, including, without limitation, a change in
              the base index year, a reasonable adjustment shall be made by
              Landlord in such revised index which would produce results
              equivalent, as nearly as possible, to those which would have been
              obtained if such Consumer Price Index had not been so revised. If
              the Consumer Price Index shall become unavailable to the public
              because publication is discontinued, or otherwise, or if
              equivalent data is not readily available to enable Landlord to
              make the adjustment referred to in the preceding sentence, then
              Landlord will substitute therefor a comparable index based upon
              changes in the cost of living or purchasing power of the consumer
              dollar published by any other governmental agency or, if no such
              index is available, then a comparable index published by a
              university, a major bank or other financial institution, or a
              comparable and recognized financial publication.

              Scope Changes) and Tenant Delays, not in excess of $6,000,000.

       (iv)   "Market Rent" shall mean the then prevailing market rental rate
              per rentable square foot of area for space comparable to the space
              to be leased by Tenant pursuant for the term of the lease of such
              space, taking into account applicable loss factors, applicable
              lengths of lease term, the creditworthiness of the tenants,
              differences in the size of the space leased, the then market
              rental conditions, the condition of the subject premises and
              comparable space, the location of amenities in the Building and

              the services of such third appraiser.

       (iv)   Within fifteen (15) days following selection of the appraisers,
              Landlord and Tenant shall each simultaneously submit to the other
              their respective determinations of the Market Rent. During the
              next seven (7) days both Landlord and Tenant shall prepare a
              written critique of the other's determination and on the seventh
              (7th) day Landlord's and Tenant's determinations (as previously
              submitted to the other party with no modifications or additions
              whatsoever) and Landlord's and Tenant's critiques shall be
              submitted to the appraisers.

       (v)    The three (3) appraisers shall then determine by majority vote
              whether the Market Rent submitted by Landlord or the Market Rent
              submitted by Tenant is the Market Rent for the Premises for the
              Extended Term in question.

       All appraisers selected pursuant to this paragraph shall have at least
       ten (10) years experience with commercial property in the area where the
       Premises are situated and have an MAI certification or be licensed
       leasing brokers based in Metropolitan Chicago, shall not have a financial
       interest in Landlord or Tenant and shall otherwise be impartial.

       If Tenant fails to appoint its appraiser in the manner and within the
       time specified in (i) above, then the Market Rent shall be the Market
       Rent determined by Landlord. If Landlord fails to appoint its appraiser
       in the manner and within the time prescribed in clause (ii), then such
       Market Rent shall be the Market Rent set forth in the Tenant's Rent
       Determination Notice.

       If the appraisers selected by Tenant and Landlord fail to appoint the
       third appraiser within the time and in the manner prescribed in clause
       (iii) above, then Landlord and Tenant shall jointly and promptly apply to
       the local office of the American Arbitration Association for the
       appointment of the third appraiser.

       The decision of the appraisers shall be binding, final and conclusive on
       the parties (unless it shall be manifest that the appraiser or one or
       more of the appraisers shall not be an impartial person) and shall be
       enforceable by either party in a court of competent jurisdiction. The
       cost of the foregoing appraisal process (including any court costs) shall
       be borne equally by the parties).
