Exhibit 10(c)
 
                              Third Amendment to
                            the 1994 Restatement of
                               Aon Savings Plan
                               ----------------

 
     Whereas, the Aon Savings Plan (the "Plan") is currently set out in the
1994 Restatement of Aon Savings Plan, which was generally effective as of
January 1, 1994 (the "Restatement").

     Whereas, the Board of Directors of Aon Corporation desires to amend the
Plan pursuant to the Board's authority to do so under Section 12.01 of the Plan.

     Now, therefore, the Plan, as set out in the Restatement, is amended as
follows, effective as of January 1, 1996:

     Section 3.01.  A new paragraph (v) of subsection (a) of Section 3.01 shall
be added to read as follows:

                    (v)  The aggregate contribution of the Companies for
                    Employees shall include a special contribution (the "Special
                    Contribution") equal to one hundred percent (100%) of the
                    Basic Pay Deferral Amounts deferred as of the Closing Date
                    by Participants who are listed on Schedule 6(a) ("RDG
                    Participants") of the Asset Purchase Agreement between Aon
                    Corporation and Resource Financial Corporation (the
                    "Agreement"). (Schedule 6(a) is attached as Exhibit A). The
                    Special Contribution shall be made only on Basic Pay
                    Deferral Amounts of up to 3% of a Participant's Compensation
                    and shall not be made on additional Basic Pay Deferral
                    Amounts. For this purpose:

                    (A)  The Closing Date shall mean the date of the sale and
                         purchase of the common stock of Ryan Dealer Group,
                         Inc., and other assets as contemplated in the
                         Agreement.

                    (B)  No additional Company contributions described in
                         Section 3.01(a)(iii) shall be posted to the accounts of
                         RDG Participants for the Plan Year beginning January 1,
                         1996. Instead, there shall be posted to the Company
                         Contribution Account of each RDG Participant such
                         Participant's share of the Special Contribution in
                         accordance with the rules of Section 4.01.

                    (C)  Notwithstanding the requirements of Section 3.02, the
                         date of the contribution of the Special Contribution
                         will be deemed to be the Closing Date, even though
                         received by the Trustee at a later or earlier date.

                                      24


 
      Section 9.02  A new subsection (h) of section 9.02 shall be added to
read as follows:

          (h) Participants who are listed on Schedule 6(a) of the Asset Purchase
              Agreement ("RDG Participants") between Aon Corporation and
              Resource Financial Corporation, shall be 100% vested on the date
              of the sale and purchase of the common stock of Ryan Dealer Group,
              Inc.

     Section 8.12.  A new section 8.12 shall be added to read as follows:

             8.12   TRUSTEE TO TRUSTEE TRANSFERS. A participant who is listed on
                    Schedule 6(a) ("RDG Participants") of the Asset Purchase
                    Agreement between Aon Corporation and Resource Financial
                    Corporation (the "Agreement") shall be entitled to direct
                    the Trustee to transfer the balance in such Participant's
                    account directly to the trustee or custodian of a cash or
                    deferred arrangement which is established by Resource
                    Financial Corporation, consistent with the requirements of
                    Section 14.03; provided, however, that no transfer will be
                    effective unless such other cash or deferred arrangement has
                    been determined to be qualified under Section 401(a) of the
                    Code.

                                      25

 
IN WITNESS WHEREOF, Aon Corporation hereby adopts this Third Amendment to the

1994 Restatement of Aon Savings Plan, effective as set forth above, as of this

1st day of August, 1996.
