     You  should  rely only on the  information  incorporated  by  reference  or
provided in this Prospectus.  We have not authorized  anyone else to provide you
with different  information.  We are not making an offer of these  securities in

     This Prospectus and the documents  "Incorporated by Reference" as discussed
under "Where You Can Find More Information"  contain forward looking  statements
within the meaning of federal  securities law. Such statements can be identified
by the use of  forward-looking  terminology  such as  "may,"  "will,"  "expect,"
"anticipate,"  "estimate,"  "continue" or other similar words.  These statements
discuss future expectations,  contain projections of results of operations or of
financial  condition  or state  other  "forward-looking"  information.  Although
management  believes  that the  expectations  reflected  in its  forward-looking
statements are based on reasonable  assumptions,  there are certain factors such
as  general  economic  conditions,  local  real  estate  conditions,  or weather
conditions  that might  cause a  difference  between  actual  results  and those
forward-looking  statements.  When considering such forward-looking  statements,
you should keep in mind the risk factors and other cautionary statements in this
Prospectus.

                                  RISK FACTORS

         An  investment  in the shares of Cintas common stock offered under this
Prospectus  involves a high  degree of risk.  The  following  risk  factors,  in
addition  to the  other  information  contained  in this  Prospectus,  should be
considered carefully in evaluating Cintas and its business.

Acquisitions

         From June 1, 1995 through the fiscal  quarter ended  February 28, 2000,
Cintas  issued  approximately  23,933,000  shares of its  common  stock and paid
approximately  $81.6 million in cash in 172 acquisitions.  As part of its growth
strategy,  Cintas intends to continue to actively pursue additional  acquisition
opportunities. In order to achieve anticipated benefits from these acquisitions,
Cintas must  successfully  integrate  any  acquired  business  with its existing
operations,  and  while it  believes  it will be able to fully  integrate  these
businesses  into Cintas,  it can give no assurance that it will be successful in
this regard.  Cintas can also give no assurance that it will be able to complete
future  acquisitions  or that all future  issuances of  securities in connection
with acquisitions will not dilute the interests of its shareholders.

Competition

         Cintas'  customers in the uniform rental and sales  industry  primarily
choose  suppliers  based upon  quality of products,  service and price.  Leading
uniform  competitors include UniFirst  Corporation,  ARAMARK Corporation and G&K
Services,  Inc. In addition to Cintas'  traditional  uniform rental competitors,
Cintas  anticipates that future competition may be with businesses that focus on
selling uniforms and other related items. If existing or future competitors seek
to gain or retain  market  share by reducing  prices,  Cintas may be required to
lower prices,  which would hurt its operating  results.  Cintas competitors also
generally compete with Cintas for acquisition candidates, which can increase the
price  for  acquisitions   and  reduce  the  number  of  available   acquisition
candidates.

Economic Conditions

         National or regional  economic  slowdowns or certain industry  specific
slowdowns may hurt Cintas' business.  Events or conditions in a particular area,
such as adverse  weather and other factors,  could also hurt operating  results.
Furthermore,  increases  in  interest  rates may lead to a decline  in  economic
activity and adversely affect operating  results.  While Cintas does not believe
that its  exposure  is greater  than that of its  competitors,  Cintas  could be
adversely  affected by increases in the prices of fabric,  fuel, wages and other
components  of product  cost  unless it could  recover  such  increases  through
increases in the prices for its services and products.  Competitive  and general
economic  conditions  might limit the ability of Cintas and its  competitors  to
increase prices to cover such increases.

Environmental Regulation

         Cintas,  and  its  competitors  in the  uniform  rental  industry,  are
regulated  by  various  local,   state  and  federal   environmental   laws  and
regulations.  These  laws  and  regulations  govern  air  emissions,  wastewater
discharges and hazardous materials management and disposal.  The most onerous of
these typically are the hazardous materials regulations. In the past, Cintas has
settled,  or contributed to the settlement of, actions or claims brought against
it which  relate to the  handling  or release  of  hazardous  materials.  In the
future,  Cintas may be required to pay material  amounts to  compensate  for the
consequences of releases of hazardous materials and wastes.  Under environmental
laws,  an owner or  operator  of real estate may be required to pay the costs of
removing  or  remediating  hazardous  materials  located  on or  emanating  from
property,  whether or not the owner or operator knew of or was  responsible  for
the presence of such  hazardous  materials.  While Cintas  regularly  engages in
environmental due diligence in connection with acquisitions,  Cintas can give no
assurance that locations that have been acquired or leased have been operated in
compliance with  environmental laws and regulations during prior periods or that
future uses or conditions will not make Cintas liable under these laws or expose
Cintas to third-party actions including tort suits.

         In 1998, the USEPA proposed Categorical  Pretreatment Standards for the
industrial  laundry  industry  which,  if  implemented,  would have  changed the
regulation of wastewater  discharges from being governed on a local level to the
federal level.  Cintas and the industry  trade  association  were  successful in
providing  USEPA  evidence that  existing,  local  regulation  was sufficient to
protect the  environment.  In 1999,  USEPA  issued a final  ruling on this issue
declaring  that  Categorical  Pretreatment  Standards  were not required for the
industrial laundry industry.

Dependence on Senior Management; Ability to Attract and Retain Quality Personnel

         Cintas' success  depends in part on the skills,  experience and efforts
of senior management and certain other key employees. If, for any reason, one or
more senior  executives or key personnel  were not to remain active with Cintas,
results of  operations  could be hurt.  Future  success  also depends on Cintas'
ability to attract and retain  qualified  managers and  technical  and marketing
personnel, as well as sufficient numbers of hourly workers.  Although Cintas has
an excellent track record of attracting and retaining  quality people,  there is
competition  in the market for the services of such  qualified  personnel  and a
tight  market for  hourly  workers.  The  failure  to  attract  and retain  such
personnel or workers could hurt the results of operations.

                                   THE COMPANY

         Cintas designs,  manufactures and implements corporate identity uniform
programs  which it rents or sells to customers  throughout the United States and
Canada.  Cintas  also  provides  ancillary  services  including  entrance  mats,
sanitation  supplies,  first aid products and services and  cleanroom  supplies.
Cintas provides these highly specialized  services to businesses of all types --
from small service and manufacturing companies to major corporations that employ
thousands of people.

         During the past five years, Cintas has made several  acquisitions which
significantly  affected Cintas' revenues and net income. These acquisitions were
completed using cash, seller-financing,  Cintas common stock or a combination of
these  methods.  Cintas  intends to continue to expand,  through  both  internal
growth,  including the  establishment of operations in new geographic areas, and
by continuing its acquisition  program of both uniform rental and sale companies
and companies that engage in the sale and  distribution  of first aid and safety
products.

         Cintas was  incorporated  under the laws of the State of  Washington in
1986 and is the successor to a business begun in 1929. Its executive offices are
located at 6800 Cintas  Boulevard,  Mason,  Ohio 45040;  telephone  number (513)
459-1200.

                              SELLING SHAREHOLDERS

         On April 8, 1998,  Cintas  consummated the acquisition of the following
affiliated entities:  Uniforms to You and Company,  Integrity Uniform Co., Pride
Manufacturing  Company,  M. Frank & Co., UTY Canada,  Ltd., Working Class, Ltd.,
Michael/Keith  Partnership and UTY Partners.  The Selling Shareholders  received
3,959,262  shares of Cintas  common  stock in  exchange  for  their  shares  and
interests in such  corporations  and  partnerships.  In June,  2000, the Selling
Shareholders  received an  additional  40,509 shares of Cintas common stock as a
result of an adjustment to the consideration payable to the Selling Shareholders
in connection with the April 8, 1998 transaction.

         The Selling  Shareholders  are offering up to 593,029  shares of Cintas
common stock under this  Prospectus  in the amounts set forth below.  No Selling
Shareholder  owns shares of Cintas  common stock other than those  offered under
this Prospectus.  If all Selling Shareholders sell all shares offered under this
Prospectus, they will not own any shares of Cintas common stock.

         Shares acquired by gift from the Selling  Shareholders may also be sold
pursuant to the Prospectus by any such donee.  This  Prospectus may also be used
by   transferees,   assignees,   distributees   and   pledgees  of  the  Selling
Shareholders.

                                 USE OF PROCEEDS

         Cintas will not receive any proceeds from the shares being sold in this
offering.

                              PLAN OF DISTRIBUTION

         Cintas  is  registering  the  shares  offered  hereby  on behalf of the
Selling  Shareholders.  Cintas has been advised by the Selling Shareholders that
they may sell or  transfer  all or a portion of the shares  offered  hereby from
time to time to third parties directly or by or through brokers, dealers, agents
or  underwriters,  who may  receive  compensation  in the  form of  underwriting
discounts,  concessions or commissions from the Selling Shareholders and/or from
purchasers  of the shares for whom they may act as agent.  However,  the Selling
Shareholders have advised Cintas that they have not entered into any agreements,
understandings or arrangements with any underwriters or broker-dealers regarding
the sale of their securities, nor is there an underwriter or coordinating broker
acting in  connection  with the  proposed  sales or  transfers  of shares by the
Selling  Shareholders.  Such sales and  transfers  of the shares may be effected
from time to time in one or more  transactions on the Nasdaq National Market, in
the over-the-counter market, in negotiated transactions or otherwise, at a fixed
price or prices,  which may be changed,  at market prices prevailing at the time
of sale, at negotiated  prices,  or without  consideration,  through put or call
options transactions relating to the shares,  through short sales of shares or a
combination of such methods of sale, or by any other legally available means.

         The  term,  "Selling  Shareholders"   includes  donees,   pledgees  and
assignees  in  interest   selling   shares   acquired  from  the  named  Selling
Shareholders after the date of this Prospectus.  Any or all of the shares may be
sold or transferred  from time to time by the Selling  Shareholders  by means of
(a) a block trade in which the broker or dealer so engaged  will attempt to sell
the  shares  as agent but may  position  and  resell a  portion  of the block as
principal to facilitate the transaction;  (b) purchases by a broker or dealer as
principal  and resale by such broker or dealer for its account  pursuant to this
Prospectus;  (c) ordinary  brokerage  transactions and transactions in which the
broker  solicits  purchasers;  (d) through the writing of options on the shares;
(e)  pledges  as  collateral  to  secure  loans,   credit  or  other   financing
arrangements  and any subsequent  foreclosure,  if any,  thereunder;  (f) gifts,
donations and  contributions;  and (g) any other legally  available  means.  The
aggregate net proceeds to the Selling  Shareholders  from the sale of the shares
will be the purchase price of such shares less any commissions.

         In order to comply  with the  securities  laws of  certain  states,  if
applicable,  the  shares  will  be  sold  in  such  jurisdictions  only  through
registered or licensed  brokers or dealers.  In addition,  in certain states the
shares may not be sold unless they have been registered or qualified for sale in
the applicable  state or an exemption  from the  registration  or  qualification
requirement is available and is complied with.

         The  Selling   Shareholders  and  any  brokers,   dealers,   agents  or
underwriters that participate in the distribution of the shares may be deemed to
be "underwriters"  within the meaning of Section 2(11) of the Securities Act, in
which event any discounts, concessions and commissions received by such brokers,
dealers,  agents or  underwriters  and any  profit on the  resale of the  shares
purchased  by them may be deemed to be  underwriting  commissions  or  discounts
under the Securities Act.  Because the Selling  Shareholders may be deemed to be
"underwriters"  within the meaning of Section 2(11) of the  Securities  Act, the
Selling Shareholders will be subject to the prospectus delivery  requirements of
the  Securities  Act, which may include  delivery  through the facilities of the
Nasdaq  National  Market.  Additionally,  the  anti-manipulative  provisions  of
Regulation  M  promulgated  under  the  Exchange  Act may  apply to sales by the
Selling Shareholders in the market.

         No underwriter,  broker,  dealer or agent has been engaged by Cintas in
connection with the distribution of the shares.

         Any shares covered by this  Prospectus  which qualify for sale pursuant
to Rule 144 under the  Securities  Act may be sold under  Rule 144  rather  than
pursuant to this Prospectus. There is no assurance that the Selling Shareholders
will sell any of the shares.  The Selling  Shareholders may transfer,  devise or
gift shares by other means not described herein.

         Cintas will pay all of the expenses incident to the registration of the
shares, other than underwriting discounts and selling commissions, if any.

         The Selling  Shareholders  may agree to indemnify any agent,  dealer or
broker-dealer  that  participates  in  transactions  involving  sales of  shares
against certain liabilities, including liabilities under the Securities Act.

         When  the  Selling   Shareholders   notify  Cintas  that  any  material
arrangement  has been entered into with a  broker-dealer  for the sale of shares
through a block trade,  special  offering,  exchange  distribution  or secondary
distribution  or a  purchase  by a  broker  or  dealer,  a  supplement  to  this
Prospectus  will be  filed,  if  required,  pursuant  to Rule  424(b)  under the
Securities  Act. The supplement  will disclose (i) the name of each such Selling
Shareholders  and of the  participating  broker-dealer(s),  (ii) the  number  of
shares  involved,  (iii) the price at which such shares  will be sold,  (iv) the
commissions  to be  paid or  discounts  or  concessions  to be  allowed  to such
broker-dealer(s),  where  applicable,  (v) that  such  broker-dealer(s)  did not
conduct any  investigation  to verify the information set out or incorporated by
reference in this Prospectus and (vi) other facts material to the transaction. A
supplement to this Prospectus will be filed if Cintas is notified by the Selling
Shareholders that a donee or pledgee intends to sell more than 500 shares.

                                                                      ---------
         Total . . . . . . . . . . . . . . . . . . . . . .              $13,000

         All  of  the  above  expenses  other  than  the  Registration  fee  are
estimates. All of the above expenses will be borne by Cintas.

Item 15.  Indemnification of Directors and Officers.

         Washington  Business   Corporation  Act,  Section  23A.08.025,   allows
indemnification  by the Registrant to any person made or threatened to be made a
party to any  proceedings,  other  than a  proceeding  by or in the right of the
Registrant,  by  reason  of the  fact  that  he is or was a  director,  officer,
employee or agent of the Registrant,  against expenses,  including judgments and
fines, if he acted in good faith and in a manner reasonably believed to be in or
not  opposed  to the best  interests  of the  Registrant  and,  with  respect to
criminal  actions,  in which he had no  reasonable  cause  to  believe  that his
conduct was unlawful.  Similar  provisions apply to actions brought by or in the
right  of the  Registrant,  except  that  no  indemnification  shall  be made in
proceedings  in which the person  shall have been  adjudged  to be liable to the
Corporation.  Indemnifications  are to be made by a majority vote of a quorum of
disinterested  directors or the written opinion of independent counsel or by the
Shareholders.

         Article V of the  Registrant's  By-Laws  provides that  indemnification
shall be  extended  to any of the  persons  described  above to the full  extent
permitted by the Washington Business Corporation Act.

Item 16.  Exhibits.

         Exhibit No.                           Description
  ------------------------   ---------------------------------------------------
              5              Opinion re: Legality
             23.1            Consent of Independent Auditors
             23.2            Consent of Counsel (contained in Exhibit 5)
              24             Power of Attorney (contained on the signature page)

Item 17.  Undertakings.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors,  officers and controlling  persons of
the  Registrant  pursuant  to the  provisions  set forth in Item 15  hereof,  or
otherwise, the Registrant has been advised that in the opinion of the Securities
and  Exchange  Commission  such  indemnification  is  against  public  policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for  indemnification  against  such  liabilities  (other than the payment by the
Registrant of expenses  incurred or paid by a director,  officer or  controlling
person of the  Registrant  in the  successful  defense  of any  action,  suit or
proceeding)  is  asserted by such  director,  officer or  controlling  person in
connection with the securities being registered,  the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit  to a  court  of  appropriate  jurisdiction  the  question  whether  such
indemnification  by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

         The undersigned Registrant hereby undertakes:

     (1) to file,  during any period in which  offers or sales are being made, a
post-effective amendment to this Registration Statement:

     (i)  to  include  any  prospectus  required  by  Section  10(a)(3)  of  the
          Securities Act of 1933;

     (ii) to reflect in the  prospectus  any facts or events  arising  after the
          effective  date of the  Registration  Statement  (or the  most  recent
          post-effective  amendment  thereof)  which,  individually  or  in  the
          aggregate, represent a fundamental change in the information set forth
          in the  Registration  Statement.  Notwithstanding  the foregoing,  any
          increase  or decrease  in volume of  securities  offered (if the total
          dollar  value of  securities  offered  would not exceed that which was
          registered)  and  any  deviation  from  the  low  or  high  end of the
          estimated  maximum  offering  range  may be  reflected  in the form of
          prospectus  filed with the  Commission  pursuant to Rule 424(b) if, in
          the aggregate,  the changes in volume and price represent no more than
          a 20% change in the maximum aggregate  offering price set forth in the
          "Calculation of Registration Fee" table in the effective  registration
          statement.

     (iii) to include  any  material  information  with  respect  to the plan of
          distribution not previously disclosed in the Registration Statement or
          any material change to such information in the Registration Statement;

Provided,  however, that paragraphs (i) and (ii) do not apply if the information
required to be included in a  post-effective  amendment by those  paragraphs  is
contained in periodic  reports filed with or furnished to the  Commission by the
registrant  pursuant to Section 13 or Section 15(d) of the  Securities  Exchange
Act of 1934 that are incorporated by reference in the registration statement.

     (2) that, for the purpose of determining any liability under the Securities
Act of 1933,  each  such  post-effective  amendment  shall be deemed to be a new
Registration  Statement  relating to the  securities  offered  therein,  and the
offering of such  securities  at the time shall be deemed to be the initial bona
fide offering thereof; and

     (3) to remove from Registration by means of a post-effective  amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     (4) that,  for purposes of determining  any liability  under the Securities
Act of 1933, each filing of the  Registrant's  annual report pursuant to Section
13(a)  or  Section  15(d)  of the  Securities  Exchange  Act  of  1934  that  is
incorporated by reference in the Registration  Statement shall be deemed to be a
new Registration  Statement relating to the securities offering therein, and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.






                                   SIGNATURES

         Pursuant  to the  requirements  of the  Securities  Act  of  1933,  the
Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-3 and has duly caused this Registration
Statement  to be  signed  on its  behalf  by  the  undersigned,  thereunto  duly
authorized, in the City of Cincinnati, State of Ohio, on June 14, 2000.
