WHEREAS, the Issuer, the Guarantors thereto and the Trustee are parties to that certain Indenture dated as of April 13, 2010 (the “Indenture”) pursuant to which the Company issued its 7.15% Senior Notes due 2020 (the “Notes”) and the Guarantors guaranteed the obligations of the Issuer under the Indenture and the Notes;

WHEREAS, the Issuer, the Guarantors thereto, Meritage Homes of North Carolina, Inc., and the Trustee are parties to the First Supplemental Indenture, dated as of April 6, 2011, pursuant to which Meritage Homes of North Carolina, Inc. was added as a Guarantor;

WHEREAS, the Issuer, the Guarantors thereto, Meritage Homes of Tennessee, Inc. and the Trustee are parties to the Fifth Supplemental Indenture, dated as of September 3, 2013, pursuant to which Meritage Homes of Tennessee, Inc. was added as a Guarantor;

WHEREAS, Section 2.01 of the Indenture contemplates that Additional Notes in an unlimited principal amount may be authenticated upon a written order of the Issuer in the form of an Officer’s Certificate of the Issuer;

WHEREAS, Section 2.01 of the Indenture also contemplates that upon receipt of an Issuer Request and Officer’s Certificate certifying that a registration statement relating to an exchange offer specified in the Registration Rights Agreement or any registration rights agreement relating to the Additional Notes is effective, the Trustee shall authenticate an additional series of Notes for issuance in exchange for the Notes tendered for exchange pursuant to such exchange offer registered under the Securities Act;

WHEREAS, the provisions contained in Section 2.01 of the Indenture and described in the immediately previous Recital contemplate that additional series of Notes may be authenticated pursuant to an Issuer Request and Officer’s Request relating to “any registration rights agreement relating to Additional Notes.”

WHEREAS, the definition of Registration Rights Agreements contained in Section 1.01 of the Indenture captures only the registration rights agreement dated as of the Issue Date (defined in the Indenture as April 13, 2010);

WHEREAS, the inconsistency between Section 2.01 of the Indenture and the definition of Registration Rights Agreement in Section 1.01 of the Indenture is a defect or ambiguity or inconsistency because Section 2.01 contemplates that unlimited amounts of Additional Notes having identical terms and conditions may be issued and that such Additional Notes may be authenticated relating to an exchange offer specified in any registration rights agreement (emphasis added), which is inconsistent with the static definition of Registration Rights Agreement.

WHEREAS, it is necessary to include registration rights agreements relating to Additional Notes in the definition of Registration Rights Agreement in order to give the holders of Additional Notes that are party to a registration rights agreement the full and intended benefits of the Indenture;

WHEREAS, Section 8.01(3) and Section 8.01(6) of the Indenture provide that the Issuer and the Trustee may, without the written consent of the Holders of the outstanding Notes, amend the Indenture as provided herein;

WHEREAS, to correct this defect and ambiguity and inconsistency, the Issuer and Trustee desire to amend the definition of Registration Rights Agreement contained in the Indenture pursuant to Section 8.01(3) and Section 8.01(6);

WHEREAS, each Guarantor hereby acknowledges and consents to amend the Indenture in accordance with the terms and conditions herein.

1. Definition of Registration Rights Agreement. The definition of Registration Rights Agreement contained in Section 1.01 of the Indenture is amended and restated in its entirety to read as follows:
