<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The General Corporation Law of the State of Delaware (&#147;DGCL&#148;) permits I/O
and its stockholders to limit directors&#146; exposure to liability for certain
breaches of the directors&#146; fiduciary duty, either in a suit on behalf of I/O or
in an action by stockholders of I/O. The Certificate of Incorporation of I/O
(the &#147;Charter&#148;) provides that a director of I/O shall not be personally liable
to I/O or its stockholders for monetary damages for breach of fiduciary duty as
a director, except for liability (i)&nbsp;for any breach of the director&#146;s duty of
loyalty to I/O or its stockholders, (ii)&nbsp;for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii)&nbsp;under Section&nbsp;174 of the DGCL or (iv)&nbsp;for any transaction from which the
director derived an improper personal benefit.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Amended and Restated Bylaws (the &#147;Bylaws&#148;) of I/O provide that I/O
shall, to the full extent permitted by applicable laws (including the DGCL),
indemnify its directors, officers, employees and agents with respect to
expenses (including counsel fees), judgments, fines, penalties and other
liabilities and amounts incurred by any such person in connection with any
threatened, pending or completed action, suit or proceeding to which such
person is or was a party, or is or was threatened to be made a party, by reason
of the fact that such person is or was serving as a director, officer, employee
or agent of I/O or any of its subsidiaries, or is or was serving at the request
of I/O or any of its subsidiaries as a director, officer, employee, agent or
trustee of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise. The Bylaws provide that the indemnification
provided pursuant to the Bylaws is not exclusive of any other rights to which
those seeking indemnification may be entitled under any provision of law,
certificate of incorporation, bylaws, governing documents, agreement, vote of
stockholders or disinterested directors or otherwise. I/O has entered into
indemnification agreements with each of its officers and directors and intends
to enter into indemnification agreements with each of its future officers and
directors. Pursuant to such indemnification agreements, I/O has agreed to
indemnify its officers and directors against certain liabilities.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I/O maintains a standard form of officers&#146; and directors&#146; liability
insurance policy which provides coverage to the officers and directors of I/O
for certain liabilities, including certain liabilities which may arise out of
this Registration Statement.

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A.&nbsp;Undertaking to Update


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


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)&nbsp;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 hereof) 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 prospectus filed with the Commission pursuant to
Rule 424(b) if, in the aggregate, the changes in volume and price represent no
more than 20&nbsp;percent change in the maximum aggregate offering price set forth
in the &#147;Calculation of Registration Fee&#148; table in this Registration Statement;
and


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)&nbsp;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;

<DIV style="font-family: 'Times New Roman',Times,serif">
<P align="left" style="font-size: 10pt">provided, however, that paragraphs (i)&nbsp;and (ii)&nbsp;above do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the Registrant pursuant to Section&nbsp;13 or 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;B.&nbsp;Undertaking With Respect to Documents Incorporated by Reference


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The undersigned Registrant hereby undertakes that, for 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 that is incorporated by reference in this Registration Statement
shall be deemed to be a new registration statement relating to the securities
offered herein, 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;C.&nbsp;Undertaking With Respect to Indemnification


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&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 Securities and Exchange 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 4. Description of Securities

Item 5. Interests of Named Experts and Counsel

Item 6. Indemnification of Directors and Officers
The General Corporation Law of the State of Delaware ("DGCL") permits I/O
and its stockholders to limit directors' exposure to liability for certain
breaches of the directors' fiduciary duty, either in a suit on behalf of I/O or
in an action by stockholders of I/O. The Certificate of Incorporation of I/O
(the "Charter") provides that a director of I/O shall not be personally liable
to I/O or its stockholders for monetary damages for breach of fiduciary duty as
a director, except for liability (i) for any breach of the director's duty of
loyalty to I/O or its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) under Section 174 of the DGCL or (iv) for any transaction from which the
director derived an improper personal benefit.
The Amended and Restated Bylaws (the "Bylaws") of I/O provide that I/O
shall, to the full extent permitted by applicable laws (including the DGCL),
indemnify its directors, officers, employees and agents with respect to
expenses (including counsel fees), judgments, fines, penalties and other
liabilities and amounts incurred by any such person in connection with any
threatened, pending or completed action, suit or proceeding to which such
person is or was a party, or is or was threatened to be made a party, by reason
of the fact that such person is or was serving as a director, officer, employee
or agent of I/O or any of its subsidiaries, or is or was serving at the request
of I/O or any of its subsidiaries as a director, officer, employee, agent or
trustee of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise. The Bylaws provide that the indemnification
provided pursuant to the Bylaws is not exclusive of any other rights to which
those seeking indemnification may be entitled under any provision of law,
certificate of incorporation, bylaws, governing documents, agreement, vote of
stockholders or disinterested directors or otherwise. I/O has entered into
indemnification agreements with each of its officers and directors and intends
to enter into indemnification agreements with each of its future officers and
directors. Pursuant to such indemnification agreements, I/O has agreed to
indemnify its officers and directors against certain liabilities.
I/O maintains a standard form of officers' and directors' liability
insurance policy which provides coverage to the officers and directors of I/O
for certain liabilities, including certain liabilities which may arise out of
this Registration Statement.

Item 9. Undertakings
A. Undertaking to Update
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:
(i) To include any prospectus required by Section 10(a)(3) of the
Securities Act;
(ii) 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 hereof) 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 prospectus filed with the Commission pursuant to
Rule 424(b) if, in the aggregate, the changes in volume and price represent no
more than 20 percent change in the maximum aggregate offering price set forth
in the "Calculation of Registration Fee" table in this Registration Statement;
and
(iii) 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;
II-4
Table of Contents
provided, however, that paragraphs (i) and (ii) above do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or 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.
B. Undertaking With Respect to Documents Incorporated by Reference
The undersigned Registrant hereby undertakes that, for 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 that is incorporated by reference in this Registration Statement
shall be deemed to be a new registration statement relating to the securities
offered herein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.
C. Undertaking With Respect to Indemnification
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 Securities and Exchange 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.
