                                AMENDMENT NO. 1
                                     TO THE
           SOURCE SERVICES CORPORATION EMPLOYEES' PROFIT SHARING PLAN



         This Amendment No. 1 to the Source Services Corporation Employees'
Profit Sharing Plan, as amended and restated effective January 1, 1989 (the
"Plan") is adopted by Source Services Corporation (the "Company") as of the 9th
day of April, 1996, effective as set forth herein.

                              W I T N E S S E T H:

         WHEREAS, the Plan was amended and restated on December 15, 1994,
effective generally as of January 1, 1989, to incorporate, among other things,
the provisions of the Tax Reform Act of 1986, as amended and subsequent laws
applicable to the Plan; and

         WHEREAS, the Company desires to amend the Plan further as set forth
herein to modify certain duties and responsibilities of the Trustee and the
Plan's administrative committee with respect to the operation of the Plan, and
to provide active participants with an opportunity to participate in sales of
Company stock in connection with an initial public offering of the Company's
stock;

         NOW THEREFORE, pursuant to the provisions of Article 12.1 of the Plan,
the Company hereby amends the Plan in the following respects:

         1.      Article 8 of the Plan hereby is amended, effective as of April
1, 1996, by adding a new Article 8.6 thereto to read as follows:

                 8.6      In the event of an initial public offering ("IPO") of
         SSC Stock, any Active Participant may elect in writing, in such manner
         and form as the Named Fiduciary for Investments may adopt, to direct
         the Trustee to sell in the IPO vested shares of SSC Stock allocated to
         his or her Company Stock Account in accordance with the provisions of
         this Article 8.6.  The aggregate amount, if any, of SSC Stock
         allocated to the Company Stock Accounts of Active Participants that
         may be sold in the IPO will be determined by the Company based on the
         advice of the managing underwriter in the IPO (the "Plan IPO
         Allocation").  An Active Participant who elects to have vested shares
         of SSC Stock sold pursuant to this Article 8.6 shall participate in
         the Plan IPO Allocation pro rata, based on such Active Participant's
         vested shares of SSC Stock held in his or her Company Stock Account
         relative to the total number of vested shares of SSC Stock held in the
         Company Stock Accounts of all Active Participants.  In the event any
         Active

Employees' Profit Sharing Plan                                            Page 2


         Participant elects to have sold less than his or her pro rata share of
         the IPO Plan Allocation, the pro rata share of the remaining IPO
         Allocation for Active Participants who elect to participate in full in
         the IPO Allocation shall be increased in the proportion that the
         vested shares of SSC Stock allocated to each such Active Participant's
         Company Stock Account bears to the total number of vested shares of
         SSC Stock of all such Active Participants who qualify to participate
         in the allocation of the remaining IPO Allocation.  For purposes of
         applying this Article 8.6, an Active Participant's vested shares of
         SSC Stock shall be equal to the number of such shares allocated to his
         or her Company Stock Account, multiplied by his or her vested
         percentage as determined under Article 6 or Article 16, as the case
         may be, as of the last day of the Fiscal Year which coincides with or
         next precedes the date of an IPO.  If the SSC Stock credited to an
         Active Participant's Company Stock Account is sold pursuant to the
         provisions of this Article 8.6, the net proceeds from such sale will
         be allocated to his or her Other Investment Account and will be
         invested in such investment options as the Active Participant may
         elect as provided in Article 11.4.

         2.      Article 10 of the Plan hereby is amended, effective as of
April 1, 1996 by deleting Article 10.2(k) thereof in its entirety.

         3.      Article 11 of the Plan hereby is amended, effective as of
April 1, 1996, by restating Article 11.3 thereof in its entirety to read as
follows:

                 11.3     Each Participant whose accounts have not been
         distributed shall have the right to direct the Trustee as to the
         exercise of voting rights with respect to the vested shares of SSC
         Stock allocated to his or her Company Stock Account.  For purposes of
         this Article 11.3, a Participant's vested shares of SSC Stock shall be
         equal to the number of such shares allocated to his or her Company
         Stock Account, multiplied by his or her vested percentage as
         determined under Article 6 or Article 16, as the case may be, as of
         the last day of the Fiscal Year which coincides with or next precedes
         the date on which such exercise of voting rights occurs, reduced by
         the number of shares of SSC Stock which have been distributed
         subsequent to such date and prior to the date on which such voting
         occurs.  The Trustee shall vote all vested shares of SSC Stock for
         which the Trustee has received directions from Participants as
         provided by this Article 11.3, in accordance with such directions.  In
         addition, the Trustee shall vote (a) all vested shares of SSC Stock
         with respect to which the Trustee has not received from Participants
         directions given in accordance with such procedures and requirements
         as the Trustee may establish and (b) all unvested shares of SSC Stock.
         The Trustee, in its discretion, shall

         accordance with the Trustee's responsibilities under ERISA to solicit
         Participants' directions as to the manner in which vested shares
         allocated to the Participants' Company Stock Accounts shall be voted
         and to ensure the confidentiality of the Participants' votes, provided
         that such procedures shall be uniformly applied to all Participants
         and shall be designed to give all Participants a fair opportunity to
         exercise the pass-through voting provided under this Article 11.3.

         IN WITNESS WHEREOF, the Company has caused this Amendment No. 1 to the
Plan to be executed by its duly authorized officers as of the date first above
