Item 2.  Acquisition or Disposition of Assets.

     As discussed  in the  attached  press  release,  on March 24, 1999,  Cintas
Corporation  announced  that it had  completed  the merger with Unitog  Company.
Unitog is a leading  provider  of high  quality  uniform  rental  services  to a
variety of industries and sells  custom-designed  uniforms primarily to national
companies in connection with their corporate image programs. Unitog manufactures
substantially all of the uniforms it rents or sells.

     The merger was approved by Unitog's  shareholders on March 24, 1999. In the
transaction a wholly-owned subsidiary of Cintas was merged with and into Unitog,
with the result that Unitog became a wholly-owned  subsidiary of a subsidiary of
Cintas, and each of Unitog's outstanding  9,478,998 shares of Common Stock (less
shares  owned by Cintas and any  subsidiary  of Cintas) was  converted  into the
right to receive  .5518 share of Cintas Common  Stock.  Cintas issued  5,072,124
shares of Cintas  Common Stock for an aggregate  value (as of March 24, 1999) of
approximately  $346,000,000.  In addition,  Cintas  assumed  options to issue an
additional  191,627  shares of Cintas Common  Stock.  The  transaction  has been
accounted for as a pooling of interests.

     The amount of consideration paid was determined by arms-length negotiations
between  Cintas and Unitog.  There was no prior  material  relationship  between
Unitog and Cintas or any of Cintas'  affiliates,  directors or officers,  or any
associate of such  directors or officers.  Cintas  intends to continue to devote
the assets acquired to Unitog's existing business.
