action or proceeding, had no reasonable cause to believe their conduct was unlawful. A similar
standard is applicable in the case of derivative actions, except that indemnification only
extends to expenses (including attorneys&#146; fees) incurred in connection with the defense or
settlement of such action, and the DGCL requires court approval before there can be any
indemnification where the person seeking indemnification has been found liable to the
corporation. The DGCL provides that it is not exclusive of other indemnification that may be
granted by a corporation&#146;s charter, by-laws, disinterested director vote, stockholder vote,
agreement, or otherwise.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The Company&#146;s Amended and Restated By-laws provide that each person who is involved in any
actual or threatened action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that he or she is or was a director or officer of the
Company, or is or was serving at the request of the Company as a director, officer, employee or
agent of another corporation or of a partnership, joint venture, trust or other enterprise,
including service with respect to an employee benefit plan, will be indemnified by the Company
to the full extent permitted by the DGCL if he or she acted in good faith and in a manner he or
she reasonably believed to be in or not opposed to the best interests of the Company. The
indemnification rights conferred by the Company&#146;s By-laws are not exclusive of any other right
to which such person seeking indemnification may be entitled under any law, by-law, agreement,
vote of stockholders or disinterested directors or otherwise.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Section&nbsp;102(b)(7) of the DGCL permits a corporation to provide in its certificate of
incorporation that a director of the corporation will not be personally liable to the
corporation or its stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability for (i)&nbsp;any breach of the director&#146;s duty of loyalty to the corporation or
its stockholders, (ii)&nbsp;acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii)&nbsp;payment of unlawful dividends or unlawful stock
purchases or redemptions, or (iv)&nbsp;any transaction from which the director derived an improper
personal benefit.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Article&nbsp;VI of the Company&#146;s Restated Certificate of Incorporation provides that to the full
extent permitted by the DGCL, as it now exists or may hereafter be amended, no director of the
Company will be liable to the Company or its stockholders for monetary damages for breach of
fiduciary duty as a director.

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 5. Interests of Named Experts and Counsel
The legality of the securities offered hereby will be passed upon for the Registrant by Ivan D.

Item 6. Indemnification of Directors and Officers
Section 145 of the Delaware General Corporation Law (the "DGCL") provides that a corporation may
indemnify directors and officers as well as other employees and agents of the corporation
against expenses (including attorneys' fees), judgments, fines, and amounts paid in settlement
in connection with specified actions, suits or proceedings, whether civil, criminal,
administrative, or investigative (other than action by or in the right of the corporation-a
"derivative action"), if they acted in good faith and in a manner they 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 their conduct was unlawful. A similar
standard is applicable in the case of derivative actions, except that indemnification only
extends to expenses (including attorneys' fees) incurred in connection with the defense or
settlement of such action, and the DGCL requires court approval before there can be any
indemnification where the person seeking indemnification has been found liable to the
corporation. The DGCL provides that it is not exclusive of other indemnification that may be
granted by a corporation's charter, by-laws, disinterested director vote, stockholder vote,
agreement, or otherwise.
The Company's Amended and Restated By-laws provide that each person who is involved in any
actual or threatened action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that he or she is or was a director or officer of the
Company, or is or was serving at the request of the Company as a director, officer, employee or
agent of another corporation or of a partnership, joint venture, trust or other enterprise,
including service with respect to an employee benefit plan, will be indemnified by the Company
to the full extent permitted by the DGCL if he or she acted in good faith and in a manner he or
she reasonably believed to be in or not opposed to the best interests of the Company. The
indemnification rights conferred by the Company's By-laws are not exclusive of any other right
to which such person seeking indemnification may be entitled under any law, by-law, agreement,
vote of stockholders or disinterested directors or otherwise.
Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of
incorporation that a director of the corporation will not be personally liable to the
corporation or its stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability for (i) any breach of the director's duty of loyalty to the corporation or
its stockholders, (ii) acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) payment of unlawful dividends or unlawful stock
purchases or redemptions, or (iv) any transaction from which the director derived an improper
personal benefit.
Article VI of the Company's Restated Certificate of Incorporation provides that to the full
extent permitted by the DGCL, as it now exists or may hereafter be amended, no director of the
Company will be liable to the Company or its stockholders for monetary damages for breach of
fiduciary duty as a director.
Table of Contents
The Company maintains directors' and officers' liability insurance which provides for payment,
on behalf of the directors and officers of the Company and its subsidiaries, of certain losses
of such persons (other than matters uninsurable under law) arising from claims, including claims
arising under the Securities Act, for acts or omissions by such persons while acting as
directors or officers of the Company and/or its subsidiaries, as the case may be.

Item 9. Undertakings
1. The undersigned Registrant hereby undertakes:
(a) 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 the 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 the 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,
Table of Contents
in the aggregate, the changes in volume and price represent no more than a 20 percent
change in the maximum aggregate offering price set forth in the "Calculation of Registration
Fee" table in the effective Registration Statement.
(iii) To include any material information with respect to the plan of distribution not
previously disclosed in the Registration Statement or any material change to such
information in the Registration Statement;
provided, however, that paragraphs (a)(i) and (a)(ii) do not apply if the Registration
Statement is on Form S-3 or Form S-8, and, 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 Section 15(d) of the
Exchange Act that are incorporated by reference in the Registration Statement.
(b) 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 herein, and the offering of such securities at that time shall be deemed
to be the initial bona fide offering thereof.
(c) 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.
2. 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 (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 the 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.
3. 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.
