and appoints
Paul Robinson and Dick Fagerstal, or either of them signing singly, the
undersigned's true and
lawful attorney-in-fact, with full power and authority to:
(1)	prepare, execute in the undersigned's name and on the undersigned's behalf,
and
submit to the U.S. Securities and Exchange Commission ("SEC") a Form ID,
including amendments thereto, and any other documents necessary or appropriate
to obtain codes and passwords enabling the undersigned to make electronic

of 1934 and the rules and regulations thereunder as amended from time to time
(the "Exchange Act");
(2)	prepare, execute, deliver and file for and on behalf of the undersigned, in

(the "Company"), Forms 3, 4, and 5 in accordance with Section 16(a) of the
Exchange Act;
(3)	do and perform any and all acts for and on behalf of the undersigned which
may

including any electronic filing thereof, complete and execute any amendment or
amendments thereto, and timely file such form with the SEC and any stock
exchange or similar authority;
(4)	seek or obtain, as the undersigned's representative and on the undersigned's

behalf, information on transactions in the Company's securities from any third

the undersigned hereby authorizes any such person to release any such

information; and
(5)	take any other action of any type whatsoever in connection with the
foregoing
which, in the opinion of such attorney-in-fact, may be of benefit to, in the
best
interest of, or legally required by, the undersigned, it being understood that
the
documents executed by such attorney-in-fact on behalf of the undersigned
pursuant to this Power of Attorney shall be in such form and shall contain such
terms and conditions as such attorney-in-fact may approve in such attorney-in-
fact's discretion.
      The undersigned hereby grants to each such attorney-in-fact full power and
authority to
do and perform any and every act and thing whatsoever requisite, necessary, or
proper to be done
in the exercise of any of the rights and powers herein granted, as fully to all
intents and purposes
as the undersigned might or could do if personally present, with full power of
substitution or
revocation, hereby ratifying and confirming all that such attorney-in-fact, or
such attorney-in-
fact's substitute or substitutes, shall lawfully do or cause to be done by
virtue of this power of
attorney and the rights and powers herein granted.  The undersigned acknowledges
that the
responsibility to file the Forms 3, 4 and 5 are the responsibility of the
undersigned, and the
foregoing attorneys-in-fact, in serving in such capacity at the request of the
undersigned, are not
assuming, nor is the Company assuming, any of the undersigned's responsibilities
to comply with
Section 16 of the Exchange Act.  The undersigned further acknowledges and agrees
that the
attorneys-in-fact and the Company are relying on written and oral information
provided by the
undersigned to complete such forms and the undersigned is responsible for
reviewing the
completed forms prior to their filing.  The attorneys-in-fact and the Company
are not responsible
for any errors or omissions in such filings.  The attorneys-in-fact and the
Company are not
responsible for determining whether or not the transactions reported could be
matched with any
other transactions for the purpose of determining liability for short-swing
profits under Section
16(b).
      This Power of Attorney shall remain in full force and effect until the
undersigned is no
longer required to file Forms 3, 4, and 5 with respect to the undersigned's
holdings of and
transactions in securities issued by the Company, unless earlier revoked by the
undersigned in a
signed writing delivered to the foregoing attorneys-in-fact.
      This Power of Attorney shall not revoke any powers of attorney previously
executed by
the undersigned.  This Power of Attorney shall not be revoked by any subsequent
power of
attorney that the undersigned may execute, unless such subsequent power of
attorney specifically
provides that it revokes this Power of Attorney by referring to the date of the
undersigned's
execution of this Power of Attorney.
      The statutory disclosures entitled "CAUTION TO THE PRINCIPAL" and
"IMPORTANT INFORMATION FOR THE AGENT" are included below solely for the purpose
of ensuring compliance with Section 5-1501B of the New York General Obligations
Law
governing the execution of a power of attorney by an individual and, except for
ensuring the
validity of this power of attorney, shall not form part of, or in any way affect
the interpretation
of, this Power of Attorney.  Notwithstanding anything to the contrary contained
herein, this
Power of Attorney is limited to the powers granted as described above and does
not grant the
attorneys and agents the authority to spend the undersigned's money or sell or
dispose of any of
the undersigned's property.
      CAUTION TO THE PRINCIPAL:
      Your Power of Attorney is an important document.  As the "principal," you
give the
person whom you choose (your "agent") authority to spend your money and sell or
dispose of
your property during your lifetime without telling you.  You do not lose your
authority to act
even though you have given your agent similar authority.
      When your agent exercises this authority, he or she must act according to
any instructions
you have provided or, where there are no specific instructions, in your best
interest.  "Important
Information for the Agent" at the end of this document describes your agent's
responsibilities.
      Your agent can act on your behalf only after signing the Power of Attorney
before a
notary public.
      You can request information from your agent at any time.  If you are
revoking a prior
Power of Attorney by executing this Power of Attorney, you should provide
written notice of the
revocation to your prior agent(s) and to the financial institutions where your
accounts are
located.
      You can revoke or terminate your Power of Attorney at any time for any
reason as long
as you are of sound mind.  If you are no longer of sound mind, a court can
remove an agent for
acting improperly.
      Your agent cannot make health care decisions for you.  You may execute a
"Health Care
Proxy" to do this.
      The law governing Powers of Attorney is contained in the New York General
Obligations
Law, Article 5, Title 15.  This law is available at a law library, or online
through the New York
State Senate or Assembly websites, www.senate.state.ny.us or
www.assembly.state.ny.us.
      If there is anything about this form that you do not understand, you
should ask a lawyer
of your own choosing to explain it to you.

IMPORTANT INFORMATION FOR THE AGENT:

      When you accept the authority granted under this Power of Attorney, a
special legal
relationship is created between you and the principal.  This relationship
imposes on you legal
responsibilities that continue until you resign or the Power of Attorney is
terminated or revoked.
You must:
(1)	act according to any instructions from the principal, or, where there are no

instructions, in the principal's best interest;
(2)	avoid conflicts that would impair your ability to act in the principal's
best interest;
(3)	keep the principal's  property separate and distinct from any assets you own
or
control, unless otherwise permitted by law;
(4)	keep a record or all receipts, payments, and transactions conducted for the
principal; and
(5)	disclose your identity as an agent whenever you act for the principal by
writing or
printing the principal's name and signing your own name as "agent" in either of
the following manner:  (Principal's Name) by (Your  Signature) as Agent, or
(your signature) as Agent for (Principal's Name).
      You may not use the principal's assets to benefit yourself or give major
gifts to yourself
or anyone else unless the principal has specifically granted you that authority
in this Power of
Attorney or in a Statutory Major Gifts Rider attached to this Power of Attorney.
 If you have that
authority, you must act according to any instructions of the principal or, where
there are no such
instructions, in the principal's best interest.  You may resign by giving
written notice to the
principal and to any co-agent, successor agent, monitor if one has been named in
this document,
or the principal's guardian if one has been appointed.  If there is anything
about this document or
your responsibilities that you do not understand, you should seek legal advice.
      Liability of agent:
      The meaning of the authority given to you is defined in New York's General
Obligations
Law, Article 5, Title 15.  If it is found that you have violated the law or
acted outside the
authority granted to you in the Power of Attorney, you may be liable under the
law for your
violation.
