Cintas Document Management Division First to Earn Industry`s Highest Security Certification

International Achievement Further Ensures Secure Destruction of Sensitive
Information
CINCINNATI--(Business Wire)--
Cintas Corporation's (Nasdaq: CTAS) Document Management Division announced today
it has become the first and only company in document destruction to become North
American AAA certified by the National Association of Information Destruction
(NAID), the international trade association for companies providing information
destruction services.

"Cintas takes tremendous pride in becoming the first company to achieve NAID
certification in North America," said Karen Carnahan, president and chief
operating officer, Document Management division. "This prestigious designation
is a reflection of our investment in state-of-the-art systems, and commitment
from our dedicated team of employee-partners working to exceed customer
expectations every day."

Every Cintas Document Management location in the U.S. and Canada is NAID
certified and operates under this criterion. This is a further step in
information security for Cintas as the company was the first to gain U.S.
national certification in August of 2008. Cintas is still the only nationally
certified company in the U.S., as Cintas continues to further the security of
its Document Management Division and shredding programs to exceed its customer`s
expectations.

Cintas` Document Management Division was established in 2003 to help protect
customers` personal and private information and help protect the environment. As
the first company to be nationally AAA certified by NAID in August 2008, Cintas
handles document shredding services as well as storage and imaging capabilities.
The company has more than 70 secure destruction and storage operations serving
86 percent of the top 150 markets in the U.S. and Canada.

NAID's mission is to promote the information destruction industry and the
standards and ethics of its member companies. Earning national AAA NAID
certification ensures Cintas' compliance with the stringent security practices
and procedures established by NAID in several areas, including employee hiring,
operational security screening, the destruction process and company assurance.
It also ensures consistency in processing the confidential and sensitive
information of Cintas customers throughout all Cintas Document Management
locations nationwide.
