Item 1.01  Entry into a Material Definitive Agreement.

     Vitesse  Semiconductor  Corporation  (the  "Company")  has  entered  into a
commitment letter,  dated June 4,  2006 (the "Letter"),  with Tennenbaum Capital
Partners,  LLC ("Tennenbaum").  Pursuant to the terms of the Letter,  Tennenbaum
agrees to lend to the Company,  through one or more funds  managed by Tennenbaum
or an affiliate  thereof,  up to $24 million (the "Initial Loan").  In addition,
Tennenbaum  will,  at the request of the Company  and upon the  satisfaction  of
certain  conditions,  make  an  additional  loan  of  up  to  $30  million  (the
"Additional  Loan" and,  together  with the Initial  Loan,  the  "Loans") to the
Company.

     The Loans will mature on July 15, 2010 and will have an interest rate equal
to LIBOR plus 4% per annum, payable in cash, plus 5% per annum, payable in kind.
Interest will be paid quarterly.  The Loans will be secured by substantially all
the assets of the Company.  The Loans may be repaid in whole or in part prior to
maturity, but if repaid (i) prior to the second anniversary of the Initial Loan,
a  "make-whole  premium" on the amount  repaid  will be payable;  (ii) after the
second anniversary of the Initial Loan and prior to the third anniversary of the
Initial Loan, at 108% of the principal amount repaid;  and (iii) after the third
anniversary and prior to maturity,  at 104% of the principal  amount repaid.

     At the closing of each Loan,  Tennenbaum  will receive a fee equal to 4% of
the principal amount of the Loan.

     In connection with the Loans,  the Company will agree,  among other things,
to limitations on the incurrence of indebtedness,  transactions with affiliates,
fundamental changes in the Company and its business, acquisitions and changes to
the Companys subordinated debt.

     The  transaction  is subject to the execution of definitive  agreements and
the satisfaction of certain conditions.  The execution of the agreements and the
Initial Loan are expected to occur during the week of June 5, 2006.

Item 2.04    Triggering Events That Accelerate or Increase a Direct Financial
             Obligation or an Obligation under an Off-Balance Sheet Arrangement.

     The Company has received a letter from U.S. Bank National  Association,  as
Trustee (the "Trustee") under the Indenture, dated as of September 22, 2004 (the
"Indenture"),   relating  to  the  Company's  1.50%   Convertible   Subordinated
Debentures due 2024. In the letter, the Trustee alleges compliance  deficiencies
under the Indenture.  Specifically, the Trustee asserts that the Company has not
complied with the following requirements:

     1.     Pursuant to the Trust Indenture Act Section 314(a)(1), file with
            the indenture trustee copies of the annual reports and of the
            information documents, and other reports which such obligor is
            required to file with the Commission pursuant to section 13 or
            section 15(d) of the Securities Exchange Act of 1934.

     2.     Section 9.6(a) of the Indenture, the Company shall deliver to the
            Trustee within 15 days after it files them with the SEC copies of
            the annual reports and of the information, documents, and other
            reports (or copies of such portions of any of the foregoing as the
            SEC may be rules and regulations prescribe) which the Company is
            required to file with the SEC pursuant to Section 13 or 15(d) of
            the Exchange Act; provided, however, the Company shall not be
            required to deliver to the Trustee any materials for which the
            Company has sought and received confidential treatment by the SEC.
            The Company also shall comply with the other provisions of Section
            3.14(a) of the TIA.

     The letter states that it serves as a 60-day notice pursuant to Article 4
of the Indenture to allow the Company to cure the compliance deficiencies.  The
letter also states that if the compliance deficiencies are not cured within 60
days of May 26, 2006, there will be an Event of Default under the Indenture and
the Trustee will seek the remedies allowed in the Indenture to protect the
interests of the bondholders.

     The Company disputes the allegations set forth in the letter from the
Trustee and will contest any attempt to declare an Event of Default under the
Indenture based on the alleged compliance deficiencies in the letter from the
Trustee.

         Approximately $96.7 million aggregate principal amount of the Company's
1.50% Convertible Subordinated Debentures due 2024 are outstanding.
