William  D.  Shovers  has been  appointed  as Chief  Financial  Officer of SMSC,
effective  June 1, 2005.  Mr.  Shovers joins SMSC with a wealth of experience in
corporate  finance and  management.  He will succeed Andrew M. Caggia,  who will

"Andy has been a tremendous  asset to SMSC," said Steven J.  Bilodeau,  Chairman
and Chief Executive  Officer.  "He has been instrumental in helping to transform
SMSC into a leading semiconductor supplier. I know that I speak on behalf of the
entire SMSC family in wishing Andy all the best in his future retirement. At the

experience in running  financial  organizations  on a global scale and I believe
that his  leadership and expertise will prove to be invaluable as we continue to
pursue our growth initiatives."

"It has been an extraordinary  five years working with an extremely  capable and
dedicated   team  at  SMSC,"  said  Andy  Caggia.   "I  am  very  proud  of  the
accomplishments we have collectively made to expand into new markets and build a
strong global  infrastructure  that will support the Company's continued growth.
Although  there is never a perfect  time to leave a job that you  enjoy,  I look
forward to pursuing other personal interests.  Though my day-to-day  involvement
with SMSC will diminish over time, I will remain close to the Company through my
board position,  and I remain excited about SMSC's growth strategy and prospects
for continued success."

Mr.  Shovers'  responsibilities  as Senior Vice  President  and Chief  Financial
Officer will include all financial and information systems functions,  including
accounting, strategic planning, forecasting, investor relations, risk management
and  treasury.  Prior to joining  SMSC,  Mr.  Shovers held the positions of Vice

various financial positions of increasing  responsibility with Tenneco Inc. over
a 17-year  period,  including  Assistant  Treasurer  of Tenneco Inc.  and,  more
recently,  as Vice  President,  Finance for Tenneco's  $1.1 billion  Monroe Auto

Most  recently,  Mr. Shovers spent several months acting as a consultant to SMSC
and was  instrumental  in completing  the  acquisition  of OASIS  SiliconSystems

"I am thrilled  about the  opportunity to assume the CFO position at SMSC and to
work with Steve and the talented team he has assembled to successfully drive the
Company  into  new  growth  markets,"  said  Bill  Shovers.  "Supported  by  the
investments SMSC has made in recent years to build its  infrastructure and round
out its  technology  expertise,  I am joining the Company at an exciting time. I
look  forward to playing an active  role in helping  SMSC to achieve its ongoing
global  growth  and  diversification   strategy,   particularly   leveraging  my
