                     Bel Agrees to Acquire Cinch Connectors
                        From Safran S.A. For $39 Million


     JERSEY CITY, New Jersey,  December 28, 2010 -- Bel Fuse Inc.  (NASDAQ:BELFA
and NASDAQ:BELFB) announced today that it has agreed to acquire Cinch Connectors
from Safran S.A. (ENXTPA:SAF),  a leading French  industrial  group,  for  $37.5
million in cash plus  approximately  $1.5 million for the  assumption of certain
expenses. The transaction will be funded with cash on hand.
     Headquartered  in Lombard,  Illinois and with  manufacturing  facilities in
Vinita,  Oklahoma,  Reynosa, Mexico and Worksop,  England, Cinch had revenue for
2009  of  approximately  $60  million.  Cinch  manufactures  a  broad  range  of
interconnect   products  for   customers   in  the   military   and   aerospace,
high-performance computing, telecom/datacom, and transportation markets. Cinch's
products  include  CIN::APSE & iQ,  Omega,  Dura-Con,  Cables,  Header & Harness
Connectors,  ModICE & ICE, and AMC  Connectors,  as well as  miniature  ribbons,
D-subminiature  connectors,  Filtered D-subminiatures,  barrier blocks and jones
plugs & sockets.
     "Cinch stands out in the highly fragmented  connector market because of its
innovative  technologies,  breadth of product  offerings,  outstanding  customer
service, and exceptional product performance," said Daniel Bernstein,  President
of Bel.  "Cinch's  products and  manufacturing  assets are a natural addition to
Bel's,  and we see attractive  growth  opportunities  in the  combination of our
extensive customer bases. We expect this acquisition to close in early 2010, and
to be accretive to Bel's earnings in 2010."
