  As previously disclosed, on July 31, 2006, Cyberonics, Inc. ( "Company") received a notice of default and demand letter ("Notice of Default") dated July 28, 2006 from Wells Fargo Bank, National Association (the "Trustee"), pursuant to which the Trustee asserted that the Company was in default of its obligations under the Indenture dated September 27, 2005 ("Indenture"), between the Company, as issuer, and the Trustee, as trustee, with respect to the Company&#x2019;s $125 million of 3.0% Senior Subordinated Convertible Notes due 2012 ("Notes"), as a result of the Company&#x2019;s failure (a) to timely file with the Securities and Exchange Commission ("SEC") its Annual Report on Form 10-K for the fiscal year ended April 28, 2006 ("2006 Form 10-K") by July 12, 2006 and (b) to deliver a copy of the 2006 Form 10-K to the Trustee by July 27, 2006.  As stated in the prior disclosure, the Company does not believe that an event of default has occurred; however, if the Company&#x2019;s interpretation is not correct, then unless the Company cured the default by filing with the SEC and delivering to the Trustee a copy of the 2006 Form 10-K by September 27, 2006, the alleged default under the Indenture would ripen into an "event of default" under the Indenture on September 27, 2006 (61 days after the date of the Notice of Default), permitting the Trustee or the holders of 25% in aggregated principal amount of the Notes to declare all unpaid principal and accrued interest on the Notes then outstanding to be immediately due and payable.<br><br>On October 2, 2006, the Company received a notice of acceleration and demand letter ("Notice of Acceleration") dated September 27, 2006 from the Trustee informing the Company that, pursuant to the Indenture, the Trustee has declared the Notes due and payable at their principal amount together with accrued and unpaid interest, and fees and expenses, and it demands that all such principal, interest, fees and expenses under the Notes be paid to the Trustee immediately.<br><br>The Company believes that neither a default nor an "event of default" has occurred under the Indenture.  Section 9.6 of the Indenture requires the Company to deliver to the Trustee "within 15 days after it files them" with the SEC copies of all annual reports and other information, documents and other reports that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended.  Section 9.6 of the Indenture specifically requires the Company to deliver a copy of its 2006 Form 10-K within 15 days after the date it is filed with the SEC.  This Indenture provision does not require the Company to file the 2006 Form 10-K by any particular date.  The Company will furnish to the Trustee copies of its 2006 Form 10-K within 15 days after it files such report with the SEC.  The Company believes that this action will comply fully with the Indenture.<br><br>To clarify its rights and responsibilities under the Indenture, the Company filed a declaratory judgment action on October 3, 2006 styled Cyberonics, Inc. v. Wells Fargo Bank, N.A., as Trustee Under Indenture, No. 06-63284, in the 165th District Court of Harris County, Texas.  In the lawsuit, the Company seeks a declaration that no event of default has occurred under the Indenture and requests attorney fees under the Declaratory Judgment Act.  The Company will pursue a declaration if the matter cannot be resolved amicably.<br><br>If the Company&#x2019;s interpretation of Section 9.6 of the Indenture is determined to be incorrect, a default and, therefore, an "event of default" will have occurred under the Indenture. If an event of default has occurred under the Indenture, all unpaid principal and accrued interest on the outstanding Notes will be due and payable immediately unless the Company negotiates an amendment to the terms of the Indenture. <br><br>Any event of default under the Indenture constitutes an event of default under the Company&#x2019;s Credit Agreement dated January 13, 2006 with Merrill Lynch Capital, a division of Merrill Lynch Business Financial Services Inc. ("Administrative Agent") and the lenders who are party thereto ("Lenders"). As disclosed in the Company&#x2019;s Current Report on Form 8-K filed with the SEC on July 27, 2006, the Company entered into a Consent and Amendment Agreement ("Consent") that same date with the Administrative Agent and Lenders providing that certain events will not constitute a default under the Credit Agreement prior to October 31, 2006, including the Company&#x2019;s failure to timely file with the SEC its 2006 Form 10-K. If a default has occurred under the Indenture and the Company is unable to negotiate an appropriate amendment to the Consent to include such default under the Indenture, then the lenders may accelerate the due date of all loans then outstanding under the Credit Agreement. As of August 4, 2006, loans aggregating $5 million in principal amount, representing the minimum for which the Company must pay interest, were outstanding under the Credit Agreement.

  Item 2.04 Triggering Events That Accelerate or Increase a Direct Financial Obligation or an Obligation Under an Off-Balance Sheet Arrangement.
  As previously disclosed, on July 31, 2006, Cyberonics, Inc. ( "Company") received a notice of default and demand letter ("Notice of Default") dated July 28, 2006 from Wells Fargo Bank, National Association (the "Trustee"), pursuant to which the Trustee asserted that the Company was in default of its obligations under the Indenture dated September 27, 2005 ("Indenture"), between the Company, as issuer, and the Trustee, as trustee, with respect to the Company's $125 million of 3.0% Senior Subordinated Convertible Notes due 2012 ("Notes"), as a result of the Company's failure (a) to timely file with the Securities and Exchange Commission ("SEC") its Annual Report on Form 10-K for the fiscal year ended April 28, 2006 ("2006 Form 10-K") by July 12, 2006 and (b) to deliver a copy of the 2006 Form 10-K to the Trustee by July 27, 2006.  As stated in the prior disclosure, the Company does not believe that an event of default has occurred; however, if the Company's interpretation is not correct, then unless the Company cured the default by filing with the SEC and delivering to the Trustee a copy of the 2006 Form 10-K by September 27, 2006, the alleged default under the Indenture would ripen into an "event of default" under the Indenture on September 27, 2006 (61 days after the date of the Notice of Default), permitting the Trustee or the holders of 25% in aggregated principal amount of the Notes to declare all unpaid principal and accrued interest on the Notes then outstanding to be immediately due and payable.
  On October 2, 2006, the Company received a notice of acceleration and demand letter ("Notice of Acceleration") dated September 27, 2006 from the Trustee informing the Company that, pursuant to the Indenture, the Trustee has declared the Notes due and payable at their principal amount together with accrued and unpaid interest, and fees and expenses, and it demands that all such principal, interest, fees and expenses under the Notes be paid to the Trustee immediately.
  The Company believes that neither a default nor an "event of default" has occurred under the Indenture.  Section 9.6 of the Indenture requires the Company to deliver to the Trustee "within 15 days after it files them" with the SEC copies of all annual reports and other information, documents and other reports that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended.  Section 9.6 of the Indenture specifically requires the Company to deliver a copy of its 2006 Form 10-K within 15 days after the date it is filed with the SEC.  This Indenture provision does not require the Company to file the 2006 Form 10-K by any particular date.  The Company will furnish to the Trustee copies of its 2006 Form 10-K within 15 days after it files such report with the SEC.  The Company believes that this action will comply fully with the Indenture.
  To clarify its rights and responsibilities under the Indenture, the Company filed a declaratory judgment action on October 3, 2006 styled Cyberonics, Inc. v. Wells Fargo Bank, N.A., as Trustee Under Indenture, No. 06-63284, in the 165th District Court of Harris County, Texas.  In the lawsuit, the Company seeks a declaration that no event of default has occurred under the Indenture and requests attorney fees under the Declaratory Judgment Act.  The Company will pursue a declaration if the matter cannot be resolved amicably.
  If the Company's interpretation of Section 9.6 of the Indenture is determined to be incorrect, a default and, therefore, an "event of default" will have occurred under the Indenture. If an event of default has occurred under the Indenture, all unpaid principal and accrued interest on the outstanding Notes will be due and payable immediately unless the Company negotiates an amendment to the terms of the Indenture.
  Any event of default under the Indenture constitutes an event of default under the Company's Credit Agreement dated January 13, 2006 with Merrill Lynch Capital, a division of Merrill Lynch Business Financial Services Inc. ("Administrative Agent") and the lenders who are party thereto ("Lenders"). As disclosed in the Company's Current Report on Form 8-K filed with the SEC on July 27, 2006, the Company entered into a Consent and Amendment Agreement ("Consent") that same date with the Administrative Agent and Lenders providing that certain events will not constitute a default under the Credit Agreement prior to October 31, 2006, including the Company's failure to timely file with the SEC its 2006 Form 10-K. If a default has occurred under the Indenture and the Company is unable to negotiate an appropriate amendment to the Consent to include such default under the Indenture, then the lenders may accelerate the due date of all loans then outstanding under the Credit Agreement. As of August 4, 2006, loans aggregating $5 million in principal amount, representing the minimum for which the Company must pay interest, were outstanding under the Credit Agreement.
