APPENDIX I

The “CAUTION TO THE PRINCIPAL” and “IMPORTANT INFORMATION FOR THE AGENT” statements below are required under the New York General Obligations Law. Notwithstanding anything to the contrary contained in such statements below, this Limited Power of Attorney is limited to the powers granted as described above and DOES NOT grant the attorney-in-fact and agent the authority to spend the undersigned’s money or sell or dispose of the undersigned’s property or any other power not expressly granted above.

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 document that you do not understand, you should ask a lawyer of your own choosing to explain it to you.

A-1

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 of 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.

APPENDIX I

The “CAUTION TO THE PRINCIPAL” and “IMPORTANT INFORMATION FOR THE AGENT” statements below are required under the New York General Obligations Law. Notwithstanding anything to the contrary contained in such statements below, this Limited Power of Attorney is limited to the powers granted as described above and DOES NOT grant the attorney-in-fact and agent the authority to spend the undersigned’s money or sell or dispose of the undersigned’s property or any other power not expressly granted above.

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 document that you do not understand, you should ask a lawyer of your own choosing to explain it to you.

A-1

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 of 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.

APPENDIX I

The “CAUTION TO THE PRINCIPAL” and “IMPORTANT INFORMATION FOR THE AGENT” statements below are required under the New York General Obligations Law. Notwithstanding anything to the contrary contained in such statements below, this Limited Power of Attorney is limited to the powers granted as described above and DOES NOT grant the attorney-in-fact and agent the authority to spend the undersigned’s money or sell or dispose of the undersigned’s property or any other power not expressly granted above.

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 document 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 of 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.
