                      HEICO CORPORATION ANNOUNCES EXPANDED
                          $300 MILLION CREDIT FACILITY

Hollywood, FL and Miami, FL, May 28, 2008  (PRIME NEWSWIRE) -- HEICO Corporation
(NYSE: HEI.A and HEI)  has entered  into an amended,  senior unsecured revolving
credit facility with a banking syndicate led by SunTrust Robinson Humphrey, Inc.
and J.P.  Morgan  Securities, Inc.  The amendment increases the revolving credit
commitment  amount  from $130 million to $300 million, which may be increased to
$500 million  under certain  circumstances.  The  borrowings  under  the amended
credit  facility  bear interest at spreads over LIBOR rates ranging from 62.5 to
225 basis  points based on leverage measurements and mature in May, 2013.  Under
certain circumstances, the maturity may be extended for two one-year periods.

The new  facility provides  the Company  additional flexibility  for its capital
needs.  HEICO has historically used its revolving credit facility principally to
fund acquisitions  and anticipates  that the  replacement facility  will also be
used mainly  for acquisitions.   Among other  new features  designed to increase
HEICO's flexibility,  the replacement  facility allows  the Company  to borrow a
portion of the facility in Euros.

Laurans A. Mendelson, HEICO's  Chairman, President and Chief  Executive Officer,
remarked,  "We  are  gratified that  HEICO's  excellent  performance and  credit
characteristics have enabled us to more than double our existing credit facility
during a time  of credit market  difficulties.  The facility  was oversubscribed
and  our banking  syndicate of  high-quality banks,  led by  SunTrust Bank   and
JPMorgan Chase Bank, shows great confidence  in HEICO as a result of  our strong
historical performance and our outlook.  We are proud of our relationships  with
them and look forward to continuing to work together."

HEICO  Corporation  is  engaged  primarily  in  certain  niche  segments  of the

Certain statements in this press release constitute forward-looking  statements,
which are  subject to  risks, uncertainties  and contingencies.   HEICO's actual
results  may differ  materially from  those expressed  in or  implied  by  those
forward-looking statements as a result of factors including, but not limited to:
lower demand  for commercial  air travel  or airline  fleet changes, which could
cause lower demand for our  goods and services; product specification  costs and
requirements, which could cause an increase to our costs to complete  contracts;
governmental  and   regulatory  demands,   export  policies   and  restrictions,
reductions  in  defense, space  or  homeland security  spending  by U.S.  and/or
foreign customers, or competition from existing and new competitors, which could
reduce our sales; HEICO's ability to introduce new products and product  pricing
levels, which could reduce  our sales or sales  growth; HEICO's ability to  make
acquisitions and achieve operating synergies from acquired businesses,  customer
credit risk, interest  rates and economic  conditions within and  outside of the
aviation,  defense, space  and electronics  industries, which  could  negatively
impact  our  costs  and  revenues; and  HEICO's  ability  to  maintain effective
internal controls,  which could  adversely affect  our business  and the  market
price of our  common stock.  Parties  receiving this material  are encouraged to
