145 of the Delaware General Corporation Law (the &#147;DGCL&#148;), permits a
corporation, under specified circumstances, to indemnify its directors,
officers, employees or agents against expenses (including attorneys&#146; fees),
judgments, fines and amounts paid in settlements actually and reasonably
incurred by them in connection with any action, suit or proceeding brought by
third parties by reason of the fact that they were or are directors, officers,
employees or agents of the corporation, if such directors, officers, employees
or agents 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 reason to believe their conduct was
unlawful.&#160; In a derivative action, i.e.,
one by or in the right of the corporation, indemnification may be made only for
expenses actually and reasonably incurred by directors, officers, employees or
agents in connection with the defense or settlement of an action or suit, and
only with respect to a matter as to which they shall have acted in good faith
and in a manner they reasonably believed to be in or not opposed to the best
interests of the corporation, except that no indemnification shall be made if
such person shall have been adjudged liable to the corporation, unless and only
to the extent that the court in which the action or suit was brought shall
determine upon application that the defendant directors, officers, employees or
agents are fairly and reasonably entitled to indemnity for such expenses
despite such adjudication of liability.</font></p>

shall be personally liable to us or any of our stockholders for monetary
damages resulting from breaches of their fiduciary duty as directors, except to
the extent such limitation on or exemption from liability is not permitted

provision of our certificate of incorporation is to eliminate our rights and
those of our stockholders (through stockholders&#146; derivative suits on our
behalf) to recover monetary damages against a director for breach of the

repay such amount if it shall ultimately be determined that he or she is not
entitled to be indemnified by the Company as authorized by relevant sections of
the DGCL.&#160; Notwithstanding the foregoing,
the Company is not required to advance such expenses to an agent who is a party
to an action, suit or proceeding brought by the Company and approved by a
majority of the members of the board of directors of the Company which alleges
willful misappropriation of corporate assets by such agent, disclosure of
confidential information in violation of such agent&#146;s fiduciary or contractual

shall, for the purposes of our amended and restated bylaws, be interpreted as
follows: (i) an &#147;other enterprise&#148; shall be deemed to include such an employee
benefit plan, including, without limitation, any plan of the Company which is
governed by the Act of Congress entitled &#147;Employee Retirement Income Security
Act of 1974,&#148; as amended from time to time; (ii) the Company shall be deemed to
have requested a person to serve an employee benefit plan where the performance
by such person of his duties to the Company also imposes duties on, or
otherwise involves services by, such person to the plan or participants or
beneficiaries of the plan; excise taxes assessed on a person with respect to an
employee benefit plan pursuant to such Act of Congress shall be deemed &#147;fines.&#148;</font></p>

where applicable, each filing of an employee benefit plan&#146;s annual report

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.&#160; 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.</font></p>

Indemnification
of Directors and Officers
Delaware Law
Section
145 of the Delaware General Corporation Law (the "DGCL"), permits a
corporation, under specified circumstances, to indemnify its directors,
officers, employees or agents against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlements actually and reasonably
incurred by them in connection with any action, suit or proceeding brought by
third parties by reason of the fact that they were or are directors, officers,
employees or agents of the corporation, if such directors, officers, employees
or agents 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 reason to believe their conduct was
unlawful.  In a derivative action, i.e.,
one by or in the right of the corporation, indemnification may be made only for
expenses actually and reasonably incurred by directors, officers, employees or
agents in connection with the defense or settlement of an action or suit, and
only with respect to a matter as to which they shall have acted in good faith
and in a manner they reasonably believed to be in or not opposed to the best
interests of the corporation, except that no indemnification shall be made if
such person shall have been adjudged liable to the corporation, unless and only
to the extent that the court in which the action or suit was brought shall
determine upon application that the defendant directors, officers, employees or
agents are fairly and reasonably entitled to indemnity for such expenses
despite such adjudication of liability.
Our
restated certificate of incorporation, as amended, provides that no director
shall be personally liable to us or any of our stockholders for monetary
damages resulting from breaches of their fiduciary duty as directors, except to
the extent such limitation on or exemption from liability is not permitted
under the DGCL.  The effect of this
provision of our certificate of incorporation is to eliminate our rights and
those of our stockholders (through stockholders' derivative suits on our
behalf) to recover monetary damages against a director for breach of the
fiduciary duty of care as a director, including breaches resulting from
negligent or grossly negligent behavior, except, as restricted by the DGCL:
3
•
for any breach of the director's duty of
loyalty to the Company or its stockholders;
•
for acts or omissions not in good faith or
that involve intentional misconduct or a knowing violation of law;
•
in respect of certain unlawful dividend
payments or unlawful stock purchases or redemptions; and
•
for any transaction from which the director
derives an improper personal benefit.
This
provision does not limit or eliminate our rights or the rights of any
stockholder to seek non-monetary relief, such as an injunction or rescission,
in the event of a breach of a director's duty of care.
If
the DGCL is amended to authorize corporate action further reducing or limiting
the liability of directors, then, in accordance with our certificate of
incorporation, the liability of our directors to us or our stockholders will be
reduced or limited to the fullest extent authorized by the DGCL, as so
amended.  Any repeal or amendment of
provisions of our restated certificate of incorporation, as amended, reducing
or limiting the liability of directors, whether by our stockholders or by
changes in law, will (unless otherwise required by law) be prospective only,
except to the extent such amendment or change in law permits us to further
reduce or limit the liability of directors on a retroactive basis.
Restated Certificate of Incorporation and Amended and Restated Bylaws
Our
restated certificate of incorporation, as amended, provides that we are
authorized, to the fullest extent permitted by applicable law, to indemnify our
current and former directors or officers (and any other person to which the
DGCL permits us to provide indemnification) through provisions in our bylaws,
agreements with such directors, officers or other persons, the vote of
stockholders or disinterested directors or otherwise, in each case, in excess
of the indemnification and advancement rights otherwise permitted by Section
145 of the DGCL, subject only to limits created by applicable Delaware law
(including the DGCL and case law), with respect to actions for breach of duty
to the Company, its stockholders and others.
Any
repeal or modification of provisions of our certificate of incorporation
affecting indemnification rights, whether by our stockholders or by changes in
law, will (unless otherwise required by law) be prospective only, except to the
extent such amendment or change in law permits us to provide broader
indemnification rights on a retroactive basis, and will not in any way diminish
or adversely affect any right or protection existing at the time of such repeal
or modification with respect to any act or omission occurring prior to such
repeal or modification.
The
rights to indemnification and advancement of expenses shall not be deemed
exclusive of any other rights which any person covered by our certificate of
incorporation may have or hereafter acquire under law, our certificate of
incorporation, our bylaws, an agreement, vote of stockholders or disinterested
directors, or otherwise.
Our
amended and restated bylaws provide that we will, to the fullest extent
authorized by applicable law, as such laws may be amended and supplemented from
time to time, indemnify our current and former agents made, or threatened to be
made, a party to an action or proceeding, whether criminal, civil,
administrative or investigative, by reason of being an agent of the Company or
a predecessor company or, at the Company's request, a director or officer of
corporation; provided, however, that the Company shall indemnify any such agent
in connection with a proceeding initiated by such agent only if such proceeding
was authorized by the board of directors of the Company.  This right of indemnification shall (i) not
be deemed exclusive of any other rights to which such indemnified parties may
be entitled under any bylaw, agreement or vote of stockholders or disinterested
directors or otherwise, both as to
4
action in their official capacities and as to action in another
capacity while holding such office, (ii) continue as to a person who has ceased
to be an agent, and (iii) inure to the benefit of the heirs, executors and
administrators of such a person.  Our
obligation to provide indemnification under our bylaws shall be offset to the
extent of any other source of indemnification or any otherwise applicable
insurance coverage under a policy maintained by the Company or any other
person.
Our
amended and restated bylaws provide that expenses incurred by an agent of the
Company in defending a civil or criminal action, suit or proceeding by reason
of the fact that he is or was an agent of the Company (or was serving at the
Company's request as a director or officer of another corporation) shall be
paid by the Company in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of such agent to
repay such amount if it shall ultimately be determined that he or she is not
entitled to be indemnified by the Company as authorized by relevant sections of
the DGCL.  Notwithstanding the foregoing,
the Company is not required to advance such expenses to an agent who is a party
to an action, suit or proceeding brought by the Company and approved by a
majority of the members of the board of directors of the Company which alleges
willful misappropriation of corporate assets by such agent, disclosure of
confidential information in violation of such agent's fiduciary or contractual
obligations to the Company or any other willful and deliberate breach in bad
faith of such agent's duty to the Company or its stockholders.
The
foregoing right to indemnification conferred by our amended and restated bylaws
is a contract right between the Company and each agent who serves in such
capacity at any time while the bylaws are in effect, and any repeal or
modification thereof shall not affect any rights or obligations then existing
with respect to any state of facts then or theretofore existing or any action,
suit or proceeding theretofore or thereafter brought based in whole or in part
upon any such state of facts.
The
board of directors, in its discretion, has the power on behalf of the Company
to indemnify any person, other than a director, made a party to any action,
suit or proceeding by reason of the fact that he or she, his or her testator or
intestate, is or was an officer or employee of the Company.
To
assure the indemnification under our amended and restated bylaws of all
directors, officers and employees who are determined by the Company or
otherwise to be or to have been "fiduciaries" of any employee benefit plan of
the corporation which may exist from time to time, Section 145 of the DGCL
shall, for the purposes of our amended and restated bylaws, be interpreted as
follows: (i) an "other enterprise" shall be deemed to include such an employee
benefit plan, including, without limitation, any plan of the Company which is
governed by the Act of Congress entitled "Employee Retirement Income Security
Act of 1974," as amended from time to time; (ii) the Company shall be deemed to
have requested a person to serve an employee benefit plan where the performance
by such person of his duties to the Company also imposes duties on, or
otherwise involves services by, such person to the plan or participants or
beneficiaries of the plan; excise taxes assessed on a person with respect to an
employee benefit plan pursuant to such Act of Congress shall be deemed "fines."
Any
repeal or modification of provisions of our amended and restated bylaws
affecting indemnification rights, whether by our board of directors,
stockholders or by changes in applicable law, will (unless otherwise required
by law) be prospective only, except to the extent such amendment or change in
law permits us to provide broader indemnification rights on a retroactive
basis, and will not in any way diminish or adversely affect any right or
protection existing thereunder with respect to any act or omission occurring
prior to such repeal or modification.

Indemnification Agreements
We
have entered into indemnification agreements with certain of our directors,
officers and certain of our employees and/or agents pursuant to which we have
agreed to indemnify and hold harmless such directors, officers, employees
and/or agents to the fullest extent authorized or permitted by the DGCL.  In addition, subject to certain exclusions
set forth below, we have agreed to indemnify and hold harmless such directors,
officers, employees and/or agents against any and all expenses (including
attorneys' fees), witness fees, judgments, fines and amounts paid in settlement
actually and reasonably incurred by such indemnitee in connection with any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (including an action by or in the
right of the Company) to which such indemnitee is, was or at any time becomes a
party, or is threatened to be made a party, by reason of the fact that such
indemnitee is, was or at any time becomes a director, officer, employee or
agent of the Company, or is or was serving or at any time serves at the request
of the Company as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise; and otherwise to the fullest extent as may be provided under the
non-exclusivity provisions of our Amended and Restated Bylaws and the DGCL.
Under
these indemnification agreements, we are obligated under certain circumstances
to advance expenses to certain of our directors, officers, employees and/or
agents, subject to such directors, officers, employees and/or agents being
required to repay such advances, if it is ultimately determined by a final and
non-appealable judicial decision that such indemnitee was not entitled to such
expenses under the DGCL, our amended and restated bylaws, the indemnification
agreement or otherwise.  All agreements
to indemnify and hold harmless any such director, officer, employee or agent
under such an indemnification agreement continues during the period in which
such indemnitee is a director, officer, employee or agent of the Company (or is
or was serving at the Company's request as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise) and shall continue so long as such indemnitee
shall be subject to any possible claim or threatened, pending or completed
action, suit or proceeding, whether civil, criminal or investigative, by reason
of the fact that such indemnitee was a director, officer, employee and/or agent
of the Company or serving in any other capacity contemplated by the
indemnification agreement.
Notwithstanding
the foregoing, under these indemnification agreements we are not
obligated to indemnify any of such directors, officers, employees
and/or agents in connection with any claim made against such indemnitee:
(i) except to the extent that the aggregate losses to be indemnified under
such indemnification agreements exceeds the sum of such losses for which such
indemnitee has been indemnified under any other indemnity provision or
pursuant to any directors and officers insurance that we purchase and maintain
on their behalf; (ii) in respect to remuneration paid to such indemnitee if it
is determined by a final judgment or other final adjudication that such
remuneration was in violation of law; (iii) on account of any suit in which
judgment is rendered against such indemnitee for an accounting of profits made
from the purchase or sale by such indemnitee of our securities pursuant to
Section 16(b) of the Exchange Act, or similar provisions of any federal, state
or local law; (iv) on account of such indemnitee's conduct which is finally
adjudged to have been knowingly fraudulent or deliberately dishonest, or which
constitutes willful misconduct; (v) on account of such indemnitee's conduct
which is the subject of action, suit or proceeding brought by the Company and
approved by a majority of our board of directors which alleges willful
misappropriation of corporate assets by such indemnitee, disclosure of
confidential information in violation of such indemnitee's fiduciary or
contractual obligations or any other willful and deliberate breach in bad faith
on such indemnitee's duty to the Company or its shareholders; (vi) on account
of any action, claim or proceeding (other than a successful proceeding by such
indemnitee to enforce rights or collect moneys due under his or her
indemnification agreement) initiated by such indemnitee unless such action,
claim or proceeding was specifically authorized by our
6
board of directors; and (vii) if a final decision by a court having
jurisdiction in the matter shall determine that such indemnification is not
lawful.

provide liability insurance for our current directors and officers.

Undertakings
The
undersigned Registrant hereby undertakes:
7
(1)   To file, during any period in which offers or
sales are being made, a post-effective amendment to 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 a 20 percent
change in the maximum aggregate offering price set forth in the "Calculation of
Registration Fee" table in the effective 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; 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;
provided
,
however
, that paragraphs (1)(i) and (l)(ii)
do not apply if the information required to be included in a post-effective
amendment by those paragraphs is contained in 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.
(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.
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 therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
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.
