4.375% SENIOR NOTES DUE 2023

TOLL BROTHERS FINANCE CORP. (the “Issuer”), a Delaware corporation, promises to pay interest on the principal amount of this Security at the rate per annum shown above. The Issuer will pay interest semiannually on April 15 and October 15 of each year, commencing on October 15, 2013, until the principal is paid or made available for payment. Interest on the Securities will accrue from the most recent date to which interest has been paid or duly provided for or, if no interest has been paid, from April 10, 2013, provided that, if there is no existing Default in the payment of interest and if this Security is authenticated between a Record Date referred to on the face hereof and the next succeeding interest payment date, interest shall accrue from such interest payment date. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

The Issuer will pay interest on the Securities (except defaulted interest, if any, which will be paid on such special payment date to Holders of record on such special Record Date as may be fixed by the Issuer) to the Persons who are registered Holders of Securities at the close of business on the April 1 and October 1 (capitalized terms not defined herein have the meanings given to those terms in the Indenture). Holders must surrender Securities to a Paying Agent to collect principal payments. The Issuer will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts.

Initially, The Bank of New York Mellon (the “Trustee”) will act as Paying Agent and Registrar. The Issuer may change or appoint any Paying Agent, Registrar or co-Registrar without notice. Toll Brothers, Inc. (the “Company”) or any of its Subsidiaries or any of their Affiliates may act as Paying Agent, Registrar or co-Registrar.

The Issuer issued the Securities under an Indenture dated as of February 7, 2012 (“Indenture”), among the Issuer, the Company, the other Guarantors and the Trustee. The terms of the Securities and the Guarantee include those stated in the Indenture (including those terms set forth in the Authorizing Resolution or supplemental indenture pertaining to the Securities of the Series of which this Security is a part) and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (“TIA”) as in effect on the date of the Indenture. The Securities and the Guarantee are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of them.

The Issuer will furnish to any Holder upon written request and without charge a copy of the Indenture and the applicable Authorizing Resolutions or supplemental indenture. Requests may be made to: Toll Brothers Finance Corp., c/o Toll Brothers, Inc., 250 Gibraltar Road, Horsham, Pennsylvania 19044, Attention: Chief Financial Officer.

Prior to January 15, 2023, the Issuer may, at its option, redeem the Securities, in whole at any time or in part from time to time, on at least 30 but not more than 60 days’ prior notice at a redemption price equal to the greater of

On and after January 15, 2023, the Securities are redeemable at the option of the Issuer, in whole at any time or in part from time to time, at a redemption price equal to 100% of the principal amount of the Securities to be redeemed, plus accrued and unpaid interest on the principal amount of the Securities being redeemed to the redemption date.

In determining the redemption price and accrued interest, interest will be calculated on the basis of a 360-day year consisting of twelve 30-day months.

If money sufficient to pay the redemption price of and accrued interest on the Securities to be redeemed is deposited with the Trustee on or before the redemption date, on and after the redemption date interest will cease to accrue on the Securities (or such portions thereof) called for redemption and such Securities (or such portions thereof) will cease to be outstanding.

If less than all the Securities are to be redeemed, the Trustee shall select the Securities to be redeemed, if the Securities are listed on a national securities exchange, in accordance with the rules of such exchange, or if the Securities are not so listed, on either a pro rata basis or by lot or by such method as the Trustee shall deem fair and appropriate. The Trustee shall make the selection from Securities outstanding and not previously called for redemption. Securities in denominations of $2,000 may only be redeemed in whole. The Trustee may select for redemption portions (equal to $2,000 or any integral multiple of $1,000 thereof) of the principal of Securities that have denominations larger than $2,000. Notice of redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each Holder whose Securities are to be redeemed at the registered address of such Holder. On and after the redemption dates interest ceases to accrue on the Securities or portions thereof called for redemption, provided that if the Issuer shall default in the payment of such Securities at the redemption price together with accrued interest, interest shall continue to accrue at the rate borne by the Securities.

The Securities are in registered form only without coupons in denominations of $2,000 and integral multiples of $1,000 thereof. A Holder may transfer or exchange Securities by presentation of such Securities to the Registrar or a co-Registrar with a request to register the

transfer or to exchange them for an equal principal amount of Securities of other denominations. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not transfer or exchange any Security selected for redemption, except the unredeemed part thereof if the Security is redeemed in part, or transfer or exchange any Securities for a period of 15 days before a selection of Securities to be redeemed.

The registered Holder of this Security shall be treated as the owner of it for all purposes.

If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent will pay the money back to the Issuer at its request. After that, Holders entitled to the money must look to the Issuer for payment unless an abandoned property law designates another Person.

Subject to certain exceptions, the Indenture, the Guarantee or the Securities may be amended or supplemented by the Issuer with the consent of the Holders of at least a majority in principal amount of the outstanding Securities and any past default or compliance with any provision relating to the Securities may be waived in a particular instance with the consent of the Holders of a majority in principal amount of the outstanding Securities. Without the consent of any Holder, the Issuer may amend or supplement the Indenture, the Guarantee or the Securities to cure any ambiguity, omission, defect or inconsistency, (provided such action does not adversely affect the rights of the Holders), to evidence the succession of another Person to the Issuer or any Guarantor, to add covenants of the Issuer or of the Guarantors under Article Four of the Indenture for the benefit of the Holders or to surrender rights or powers conferred upon the Issuer or the Guarantors by the Indenture, to add Events of Default for the benefit of the Holders, to change or eliminate any provisions of the Indenture, (provided such change or elimination shall become effective only when none of the Securities are outstanding), to add Guarantors, to provide for the acceptance of appointment by a successor Trustee or facilitate the administration of the trusts under the Indenture by more than one Trustee, to close the Indenture as to authentication and delivery of additional Securities, to supplement Indenture provisions to permit or facilitate defeasance and discharge of the Securities, (provided such action does not adversely affect the rights of the Holders), to provide that specific Indenture provisions shall not apply to an unissued Series of Securities, to provide for uncertificated Securities in addition to or in place of certificated Securities, to create a Series and establish its terms, to remove a Guarantor, other than the Company, which, in accordance with the terms of the Indenture, ceases to be liable in respect of the Guarantee, or to make any other change, (provided such action does not adversely affect the rights of any Holder).

A director, officer, employee or stockholder, as such, of the Issuer shall not have any liability for any obligations of the Issuer under the Securities or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation.
