ITEM 2.04   TRIGGERING EVENTS THAT ACCELERATE OR INCREASE A DIRECT FINANCIAL
            OBLIGATION OR AN OBLIGATION UNDER AN OFF-BALANCE SHEET ARRANGEMENT.

         Vitesse Semiconductor Corporation (the "Company") is a party to a
Second Amended and Restated Loan and Security Agreement (the "Agreement") with
Silicon Valley Bank (the "Bank"), a copy of which is included in this Form 8-K
as Exhibit 10.1.

         On May 15, 2006, the Bank notified the Company that Events of Default
have occurred under the Agreement. Specifically, the Bank assets that:

         (i) the Company has failed to meet its reporting obligations under
Section 6.2(a) of the Agreement as a result of the Company's failure to file its
Quarterly Report on Form 10-Q for the quarter ended March 31, 2006;

         (ii) an apparent failure to meet the liquidity covenant contained in
Section 6.7 of the Agreement;

         (iii) alleged misrepresentations under the Agreement; and

         (iv) the occurrence of a "Material Adverse Change" (as defined in the
Agreement).

         The Bank's notice also states that the amount outstanding under the
Agreement currently exceeds the Borrowing Base (as defined in the Agreement).
The Bank's notice states that, until the Events of Default are cured to the
satisfaction of the Bank, the Company is obligated to pay Default Interest as
set forth in Section 2.4(c) of the Agreement and the Bank will not make any
further advances to the Company.

         While an Event of Default occurs and continues, the Agreement provides
that the Bank may, without notice or demand, exercise remedies as provided in
the Agreement, including but not limited to:

                  (a) declaring all Obligations (as defined in the Agreement)
         immediately due and payable;

                  (b) stop advancing money or extending credit for the Company's
         benefit under the Agreement or under any other agreement between the
         Company and the Bank;

                  (c) demanding that the Company (i) deposit cash with the Bank
         in an amount equal to the aggregate amount of any Letters of Credit
         remaining undrawn, as collateral security for the repayment of any
         future drawings under such Letters of Credit, and the Company shall
         forthwith deposit and pay such amounts, and (ii) pay in advance all
         Letter of Credit fees scheduled to be paid or payable over the
         remaining term of any Letters of Credit;

                  (d) applying to the Obligations any balances and deposits of
         the Company it holds or any amount held by the Bank owing to or for the
         credit or the account of the Company;

                  (e) placing a "hold" on any account maintained with the Bank
         and/or deliver a notice of exclusive control, any entitlement order, or
         other directions or instructions pursuant to any Control Agreement or
         similar agreements providing control of any Collateral (as defined in
         the Agreement); and


<page>


                  (f) exercising all rights and remedies available to the Bank
         under the Loan Documents (as defined in the Agreement) or at law or
         equity, including all remedies provided under the Uniform Commercial
         Code (including disposal of the Collateral pursuant to the terms
         thereof).

         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 Agreement 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 is presently 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 would 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 Agreement. 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 with respect to such financing 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 Agreement, it would have a material adverse effect on the
Company's operations, liquidity and financial condition.
