     (e)   Material Compensatory Plan, Contract or Arrangement.

         On March 20, 2009, the Compensation Committee of the Board of Directors
of Rock-Tenn Company (the "Company") approved an amendment to the Company's
Supplemental Executive Retirement Plan (the "SERP"). The SERP amendment provides
that the lump sum payout under the level 3 benefit would be calculated using a
discount rate of 2.645%, which was the 10 year Treasury rate on March 20, 2009,
rather than having the 10 year Treasury rate reset every six months as
previously provided under the SERP. The rate will be used in combination with
the mortality table published in Revenue Ruling 2001-62 for purposes of
discounting lump sum payments made under the SERP at benefit level 3. Currently,
only Mr. James A. Rubright, the Company's Chairman and Chief Executive Officer,
participates in the SERP at benefit level 3.



         Pursuant to the requirements of the Securities Exchange Act of 1934,
the registrant has duly caused this report to be signed on its behalf by the
undersigned hereunto duly authorized.
