<P align="left" style="font-size: 10pt"><B>Item&nbsp;6. </B><B><I>Indemnification of Directors and Officers</I></B><B>.</B>



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Article&nbsp;VIII of Cyberonics&#146; Certificate of Incorporation, a copy of which is filed as Exhibit
4.1, provides that directors, officers, employees and agents shall be indemnified to the fullest
extent permitted by the Delaware General Corporation Law (&#147;DGCL&#148;).


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145 of the DGCL authorizes, inter alia, a corporation to indemnify any person
(&#147;indemnitee&#148;) who was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, by or in the right of the corporation, by reason of the
fact that such person is or was an officer or director of such corporation, or is or was serving at
the request of such corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise. The amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or proceeding, provided
that he acted in good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. A Delaware corporation may indemnify past or
present officers and directors of such corporation or of another corporation or other enterprise at
the former corporation&#146;s request, in an action by or in the right of the corporation to procure a
judgment in its favor under the same conditions, except that no indemnification is permitted
without judicial approval if such person is adjudged to be liable to the corporation. Where an
officer or director is successful on the merits or otherwise in defense of any action referred to
above, or in defense of any claim, issue or matter therein, the corporation must indemnify him
against the expenses (including attorney&#146;s fees) which he actually and reasonably incurred in
connection therewith. Section&nbsp;145 further provides that any indemnification shall be made by the
corporation only as authorized in each specific case upon a determination by the (i)&nbsp;stockholders,
(ii)&nbsp;board of directors by a majority vote of a quorum consisting of directors who were not parties
to such action, suit or proceeding or (iii)&nbsp;independent counsel if a quorum of disinterested
directors so directs. Section&nbsp;145 provides that indemnification pursuant to its provisions is not
exclusive of other rights of indemnification to which a person may be entitled under any bylaw,
agreement, vote of stockholders or disinterested directors or otherwise.

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The undersigned Registrant hereby undertakes:


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)&nbsp;To file, during any period in which offers or sales are being made, a post-effective
amendment to this registration statement:



<P align="left" style="margin-left:3%; font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) To include any prospectus required by Section&nbsp;10(a)(3) of the Securities Act;



<P align="left" style="margin-left:3%; font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) To reflect in the prospectus any facts or events arising after the effective date of
this Registration Statement (or the most recent post-effective amendment thereof) which,
individually or in the aggregate, represent a fundamental change in the information set forth in
this Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume
of securities offered (if the total dollar value of securities offered would not exceed that
which was registered) and any deviation from the low or high end of the estimated maximum
offering range may be reflected in the form of a prospectus filed with the Commission pursuant
to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a
20% change in the maximum aggregate offering price set forth in the &#147;Calculation of Registration
Fee&#148; table in the effective registration statement;



<P align="left" style="margin-left:3%; font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) To include any material information with respect to the plan of distribution not
previously disclosed in this Registration Statement or any material change to such information
in this Registration Statement; provided, however, that paragraphs (1)(a) and (1)(b) do not
apply if the information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the Registrant pursuant to Section&nbsp;13 or
Section 15(d) of the Exchange Act that are incorporated by reference in this Registration
Statement.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)&nbsp;That, for the purpose of determining any liability under the Securities Act, each such
post-effective amendment shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)&nbsp;To remove from registration by means of a post-effective amendment any of the securities
being registered which remain unsold at the termination of the offering.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4)&nbsp;That, for the purposes of determining any liability under the Securities Act, each filing
of the Registrant&#146;s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act
(and, where applicable, each filing of an employee benefit plan&#146;s annual report pursuant to Section
15(d) of the Exchange Act) that is incorporated by reference in this Registration Statement shall
be deemed to be a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona fide offering
thereof.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5)&nbsp;Insofar as indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers and controlling persons of the Registrant pursuant to the
foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the
Commission such indemnification is against public policy as expressed in the Securities Act and is,
therefore, unenforceable. In the event that a claim for indemnification against such liabilities
(other than the payment by the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action, suit or proceeding)
is asserted by such director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter has been settled
by controlling precedent, submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities Act and will be
governed by the final adjudication of such issue.

Item 6.
Indemnification of Directors and Officers
.
Article VIII of Cyberonics' Certificate of Incorporation, a copy of which is filed as Exhibit
4.1, provides that directors, officers, employees and agents shall be indemnified to the fullest
extent permitted by the Delaware General Corporation Law ("DGCL").
Section 145 of the DGCL authorizes, inter alia, a corporation to indemnify any person
("indemnitee") who was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, by or in the right of the corporation, by reason of the
fact that such person is or was an officer or director of such corporation, or is or was serving at
the request of such corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise. The amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or proceeding, provided
that he acted in good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. A Delaware corporation may indemnify past or
present officers and directors of such corporation or of another corporation or other enterprise at
the former corporation's request, in an action by or in the right of the corporation to procure a
judgment in its favor under the same conditions, except that no indemnification is permitted
without judicial approval if such person is adjudged to be liable to the corporation. Where an
officer or director is successful on the merits or otherwise in defense of any action referred to
above, or in defense of any claim, issue or matter therein, the corporation must indemnify him
against the expenses (including attorney's fees) which he actually and reasonably incurred in
connection therewith. Section 145 further provides that any indemnification shall be made by the
corporation only as authorized in each specific case upon a determination by the (i) stockholders,
(ii) board of directors by a majority vote of a quorum consisting of directors who were not parties
to such action, suit or proceeding or (iii) independent counsel if a quorum of disinterested
directors so directs. Section 145 provides that indemnification pursuant to its provisions is not
exclusive of other rights of indemnification to which a person may be entitled under any bylaw,
agreement, vote of stockholders or disinterested directors or otherwise.
Section 145 of the DGCL also empowers Cyberonics to purchase and maintain insurance on behalf
of any person who is or was an officer or director of Cyberonics against liability asserted against
or incurred by him in any such capacity, whether or not Cyberonics would have the power to
indemnify such officer or director against such liability under the provisions of Section 145.
Cyberonics intends to purchase and maintain a directors' and officers' liability policy for such
purposes.

Item 9.
Undertakings
The undersigned Registrant hereby undertakes:
(1) To file, during any period in which offers or sales are being made, a post-effective
amendment to this registration statement:
(a) To include any prospectus required by Section 10(a)(3) of the Securities Act;
(b) To reflect in the prospectus any facts or events arising after the effective date of
this Registration Statement (or the most recent post-effective amendment thereof) which,
individually or in the aggregate, represent a fundamental change in the information set forth in
this Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume
of securities offered (if the total dollar value of securities offered would not exceed that
which was registered) and any deviation from the low or high end of the estimated maximum
offering range may be reflected in the form of a prospectus filed with the Commission pursuant
to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a
20% change in the maximum aggregate offering price set forth in the "Calculation of Registration
Fee" table in the effective registration statement;
(c) To include any material information with respect to the plan of distribution not
previously disclosed in this Registration Statement or any material change to such information
in this Registration Statement; provided, however, that paragraphs (1)(a) and (1)(b) do not
apply if the information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the Registrant pursuant to Section 13 or
Section 15(d) of the Exchange Act that are incorporated by reference in this Registration
Statement.
(2) That, for the purpose of determining any liability under the Securities Act, each such
post-effective amendment shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
(3) To remove from registration by means of a post-effective amendment any of the securities
being registered which remain unsold at the termination of the offering.
(4) That, for the purposes of determining any liability under the Securities Act, each filing
of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act
(and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section
15(d) of the Exchange Act) that is incorporated by reference in this Registration Statement shall
be deemed to be a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona fide offering
thereof.
(5) Insofar as indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers and controlling persons of the Registrant pursuant to the
foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the
Commission such indemnification is against public policy as expressed in the Securities Act and is,
therefore, unenforceable. In the event that a claim for indemnification against such liabilities
(other than the payment by the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action, suit or proceeding)
is asserted by such director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter has been settled
by controlling precedent, submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities Act and will be
governed by the final adjudication of such issue.
