CAMARILLO, Calif.--(BUSINESS WIRE)--May 17, 2006--Vitesse Semiconductor
Corporation (Nasdaq:VTSS) provides updates regarding certain recent events.

Vitesse Appoints New Executive Officers

Vitesse announced today that Christopher R. Gardner,  the Acting Chief Executive
Officer of Vitesse,  has been appointed  Chief  Executive  Officer.  Mr. Gardner
joined Vitesse in 1986. He served as Vice President and Chief Operating Officer
from  November 2000 to June 2002.  From June 2002 until he was appointed  Acting
Chief  Executive  Officer on April 18,  2006,  he served as Vice  President  and
General  Manager of the Network  Products  Division.  Mr.  Gardner  received his
B.S.E.E.  from  Cornell  University  and his  M.S.E.E.  from the  University  of
California at Berkeley.

Vitesse  also  announced  that Shawn C.A.  Hassel of Alvarez & Marsal,  LLC, the
Acting Chief  Financial  Officer of Vitesse,  has been appointed Chief Financial
Officer.  Since July 2001,  Mr.  Hassel has been and  continues to be a Managing
Director  of  Alvarez &  Marsal,  specializing  in  developing  operational  and
financial solutions for companies in transition. Prior to joining Alvarez &
Marsal,  Mr. Hassel spent seven years with Arthur  Andersen's  corporate finance
and  turnaround  division  where he served as a Director.  Mr. Hassel earned his
B.S.  degree in Finance and  Accounting  from the University of Arizona and is a
licensed Certified Public Accountant.

Louis R.  Tomasetta,  Chief  Executive  Officer,  Yatin  Mody,  Chief  Financial
Officer, and Eugene F. Hovanec, Executive Vice President have been terminated as
officers and employees of Vitesse. As previously reported, these officers had
been placed on administrative leave by Vitesse because of such individuals'
involvement  with  issues  related to the  integrity  of  documents  relating to
Vitesse's stock option grant process.

Vitesse's  Chairman  of the Board,  John C. Lewis,  said,  "This has been a very
challenging  time for the Company.  As a Board, we have taken quick and decisive
action  that  we  believe  is in the  best  interests  of the  Company  and  its
shareholders.  The new management team has done an excellent job in a very short
period of time to address the pending challenges to Vitesse. Moreover, Chris
Gardner has been  instrumental  in providing  leadership  during this transition
period. The Board has complete confidence in the new executive team."

Internal Investigation

As previously disclosed, the Company's Board of Directors has appointed a
Special Committee of independent directors to conduct an internal investigation
relating to past stock option grants, the timing of such grants and other
related accounting and documentation issues. The scope of the internal
investigation was previously expanded to include issues relating to the
Company's practices in connection with credits issued to and requested by
customers (for returned products or otherwise) and the related accounting
treatment, as well as the application of payments received to the proper
accounts receivable. The internal investigation has now been further expanded to
include a review of the Company's (i) general revenue recognition policies and
practices and (ii) practices that may have affected the Company's cash position
at the end of certain reporting periods.

Credit Facility

The Company has received notice from Silicon Valley Bank that Events of Default
have occurred under the credit facility between Silicon Valley Bank and the
Company. The notice states that the Events of Default include the Company's
failure to file its Quarterly Report on Form 10-Q for the quarter ended March
31, 2006, an apparent failure to meet the liquidity covenants under the credit
facility, certain alleged misrepresentations under the credit facility and a
material adverse change in the Company. The notice also states that the amount
outstanding under the credit facility currently exceeds the permitted borrowing
base under the facility.

The Bank states that it is entitled to exercise any and all remedies available
under the credit facility and the related security documents, and that, until
all Events of Default are cured, the Company is required to pay default interest
under the credit facility and that no further advances will be made by the Bank.
The Company reserves the right to contest various asserted Events of Default and
does not believe it is necessary or appropriate for the Bank to assert further
remedies.

At May 15, 2006, approximately $10 million was drawn and outstanding under this
credit facility plus approximately $4.2 million in issued but undrawn standby
letter of credits, and the Company had un-restricted cash and un-restricted cash
equivalents of approximately $13.2 million.

The Company presently is in active discussions with the Bank and believes that
it has reached a conceptual agreement on the potential terms of a short-term
forbearance that should allow the Company to continue its efforts to obtain
additional financing. It is contemplated that as part of the agreement with the
Bank, the Company would repay $5 million of the amount currently outstanding
under the credit facility. No assurances can be given that the Bank and the
Company will actually reach agreement on the forbearance.

The Company has engaged an investment banking firm to assist in obtaining
additional financing. The Company has received non-binding indications of
interest and is currently evaluating these indications of interest. No assurance
can be given that any additional financing can be obtained or, if obtained, will
be on terms favorable to the Company. Any securities issued in the financing
will not be registered under the Securities Act of 1933 and may not be offered
or sold in the United States absent registration or an applicable exemption from
the registration requirements.

If additional financing is not obtained and/or the Bank takes further action
under the credit facility, it would have a material adverse effect on the
Company's operations, liquidity and financial condition.

Vitesse's President and CEO, Chris Gardner, said, "In spite of the recent
challenges we face with respect to our financial reporting and other issues,
Vitesse remains focused on executing our strategic business plan to capitalize
on the investments we've made. I'm pleased that we continue to see broad-based
growth in customer demand across our three business units and I'm encouraged by
the ongoing support shown by our employees, suppliers and customers."
