Morgan Securities LLC (the “Representative”) and the other underwriters listed on Schedule A hereto (each, an “Underwriter” and collectively, the “Underwriters”). The Notes are to be issued pursuant to the provisions of an Indenture dated as of May 1, 2012 (the “Base Indenture”) and a separate supplemental indenture with respect to each series of Notes to be dated as of the Closing Date (collectively, the “Supplemental Indentures,” and together with the Base Indenture, the “Indenture”) among the Company, the Guarantors (as defined below) and American Stock Transfer & Trust Company, LLC, as trustee (the “Trustee”). The Company’s obligations under the Indenture and each series of Notes will be unconditionally guaranteed (the “Guarantees”), jointly and severally, by each of the subsidiaries of the Company listed on the signature pages hereof (the “Guarantors”). The Company and the Guarantors are collectively referred to herein as the “Issuers,” and the Notes and the Guarantees are collectively referred to herein as the “Securities.”

7. Indemnification.

(a) The Issuers, jointly and severally, agree to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and the directors, officers, employees, affiliates and agents of each of the foregoing (collectively, the “Underwriter Indemnified Parties”), from and against any and all losses, claims, damages, liabilities and judgments caused by (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages, judgments or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representative expressly for use therein. The foregoing indemnity agreement shall be in addition to any liability that the Issuers may otherwise have.

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Issuers, their directors, their officers who sign the Registration Statement and any person controlling the Issuers within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (collectively, the “Issuer Indemnified Parties”), to the same extent as the foregoing indemnity from the Issuers to the Underwriter Indemnified Parties but only with reference to information relating to an Underwriter furnished in writing by or on behalf of such Underwriter expressly for use in the Registration Statement, the Prospectus, the Preliminary Prospectus, any Issuer Free Writing Prospectus or any Time of Sale Information.

-14-

(c) In case any action shall be brought against any indemnified party, based upon the Preliminary Prospectus, the Registration Statement, any Issuer Free Writing Prospectus, any Time of Sale Information or the Prospectus or any amendment or supplement thereto and with respect to which indemnity may be sought against an indemnifying party, the indemnified party shall promptly notify the indemnifying party in writing and the indemnifying party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses. Such indemnified party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment of such counsel shall have been specifically authorized in writing by the indemnifying party, (ii) the indemnifying party shall have failed to assume the defense and employ counsel or (iii) the named parties to any such action (including any impleaded parties) include both such indemnified party and the indemnifying party and such indemnified party shall have been advised by such counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party (in which case the indemnifying party shall not have the right to assume the defense of such action on behalf of such indemnified party, it being understood, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all such indemnified parties, which firm shall be designated in writing by the Representative (in the case of the Underwriter Indemnified Parties) and the Company (in the case of the Issuer Indemnified Parties) and that all such fees and expenses shall be reimbursed as they are incurred). No indemnifying party shall be liable for any settlement of any such action effected without the written consent of the Company (if the Issuers are the indemnifying parties) or the Representative (if the Underwriters are the indemnifying parties) but if settled with such written consent, the indemnifying parties agree to indemnify and hold harmless the indemnified parties from and against any loss or liability by reason of such settlement. An indemnifying party shall not, without the prior written consent of the indemnified parties, effect any settlement of any pending or threatened proceeding in respect of which the indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and does not contain any admission of guilt in respect of any indemnified party.

(d) If the indemnification provided for in this Section 7 is unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or judgments referred to therein, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities and judgments (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuers on the one hand and the Underwriters on the other hand from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is

-15-

appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Issuers and the Underwriters in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or judgments, as well as any other relevant equitable considerations. The relative benefits received by the Issuers and the Underwriters shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company, and the compensation received by the Underwriters (based on discount to investors on resale), bear to the sum of such total net proceeds and such compensation. The relative fault of the Issuers and the Underwriters shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Issuers or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Issuers and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or judgments referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

The Underwriters confirm and the Issuers acknowledge that the statements with respect to the public offering of the Securities by the Underwriters set forth in the third and eighth (with caption “Short positions”) paragraphs of the section entitled “Underwriting” in the Preliminary Prospectus Supplement and the Prospectus Supplement constitute the only information concerning such Underwriter furnished in writing to the Issuers by or on behalf of such Underwriter specifically for inclusion in the Registration Statement, the Prospectus, Preliminary Prospectus, Issuer Free Writing Prospectus and the Time of Sale Information for all purposes under this Agreement.

8. Conditions of Underwriters’ Obligation. The obligation of the Underwriters to purchase the Securities under this Agreement is subject to the satisfaction of each of the following conditions:

(a) All the representations and warranties of the Issuers contained in this Agreement shall be true and correct as of the Time of Sale and on the Closing Date with

-16-

the same force and effect as if made on and as of the Time of Sale and on and as of the Closing Date. The Issuers shall have performed or complied with all of their agreements herein contained and required to be performed or complied with by them at or prior to the Closing Date.

(b) (i) No stop order suspending the effectiveness of the Registration Statement shall have been issued and no proceedings for that purpose or pursuant to Section 8A of the Act against the Company in connection with the offering of the Securities shall have been commenced or shall be pending before or threatened by the Commission, (ii) every request for additional information on the part of the Commission shall have been complied with in all material respects and (iii) no stop order suspending the sale of the Securities in any jurisdiction referred to in Section 6(h) shall have been issued and no proceeding for that purpose shall have been commenced or shall be pending or threatened which would, in your reasonable judgment, make it impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities.

(c) Subsequent to the execution and delivery of this Agreement and prior to the Closing Date, there shall not have been any downgrading, nor shall any notice have been given of any intended or potential downgrading or of any review for a possible change that does not indicate the direction of the possible change, in the rating accorded any Issuer’s debt by any “nationally recognized statistical rating organization,” as such term is defined in Section (3)(a)(62) of the Exchange Act.

(d) (i) Since the date of the latest balance sheet included in the Registration Statement, the Time of Sale Information and the Prospectus there shall not have been any material adverse change, or any development involving a prospective material adverse change, in the condition, financial or otherwise, or in the earnings, affairs or business prospects, whether or not arising in the ordinary course of business, of the Company and its subsidiaries taken as a whole, (ii) since the date of the latest balance sheet included in the Registration Statement, the Time of Sale Information and the Prospectus there shall not have been any material change in the capital stock or in the long-term debt of the Company or any of its subsidiaries from that set forth or contemplated in the Registration Statement, the Time of Sale Information and the Prospectus and (iii) the Company and its subsidiaries shall have no liability or obligation, direct or contingent, which is material to the Company and its subsidiaries, taken as a whole, other than those set forth or contemplated in the Registration Statement, the Time of Sale Information and the Prospectus.

(e) You shall have received on the Closing Date a certificate, dated the Closing Date, signed by (i) Donald R. Horton or Donald J. Tomnitz and (ii) Bill W. Wheat or Stacey H. Dwyer in their capacities as (A) the Chairman of the Board or Chief Executive Officer and President and (B) Chief Financial Officer or Treasurer of the Company, respectively, confirming the matters set forth in paragraphs (a), (b), (c) and (d) of this Section 8.

-17-

(f) You shall have received on the Closing Date letters (satisfactory to you and counsel for the Underwriters), dated the Closing Date, of Gibson, Dunn & Crutcher LLP, special counsel for the Company, in the form previously agreed between such special counsel and counsel for the Underwriters.

(g) You shall have received on the Closing Date letters, dated the Closing Date, of Cahill Gordon & Reindel LLP, counsel for the Underwriters, in form and substance satisfactory to the Underwriters.

(h) You shall have received letters on and as of the date of this Agreement and the Closing Date, in form and substance satisfactory to you, from PricewaterhouseCoopers LLP, an independent registered public accounting firm, with respect to the financial statements and certain financial information contained in the Registration Statement, the Time of Sale Information (including the Preliminary Prospectus) and the Prospectus.

(i) (i) Neither the Company nor any of its subsidiaries shall have sustained since the date of the latest audited financial statements in the Time of Sale Information and the Prospectus any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Time of Sale Information and the Prospectus or (ii) since such date there shall not have been any change in the capital stock, net revenues, per share or total amounts of income before extraordinary items or of net income or long-term debt of the Company or any of its subsidiaries or any change, or any development involving a prospective change, in or affecting the general affairs, management, financial position, stockholders’ equity or results of operations of the Company and its subsidiaries, otherwise than as set forth or contemplated in the Time of Sale Information and the Prospectus, the effect of which, in any such case described in clause (i) or (ii), is, in the judgment of the Representative, so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities being delivered on the Closing Date on the terms and in the manner contemplated in the Time of Sale Information and the Prospectus.

(j) The Issuers shall have furnished to you such other documents and certificates as to the accuracy and completeness of any statement in the Registration Statement, any Issuer Free Writing Prospectus, any Time of Sale Information and the Prospectus as you reasonably may request.

(k) You shall have been furnished with such additional documents and certificates as you or counsel for the Underwriters may reasonably request.

All such opinions, certificates, letters and other documents will be in compliance with the provisions hereof only if they are reasonably satisfactory in form and substance to you and your counsel.

-18-

Any certificate or document signed by any officer of the Issuers and delivered to you or to your counsel shall be deemed a representation and warranty by the Issuers to the Underwriters as to the statements made therein.

9. Default by an Underwriter. If any one Underwriter shall fail to purchase and pay for any of the Notes agreed to be purchased by such Underwriter hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of the 2018 Notes and the 2023 Notes set forth opposite their names in Schedule A hereto bears to the aggregate principal amount of the 2018 Notes and the 2023 Notes set forth opposite the names of all the remaining Underwriters) the Notes which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Notes which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Notes set forth in Schedule A hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Notes, and if such non-defaulting Underwriters do not purchase all of the Notes, this Agreement will terminate without liability to any non-defaulting Underwriter or the Company except that the provisions of Sections 5(l) and 7 shall at all times be effective and shall survive such termination. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five business days, as the Representative shall determine in order that the required changes in the Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company or any non-defaulting Underwriter for damages occasioned by its default hereunder.

10. Representations and Warranties by and Agreements of the Underwriters. Each Underwriter hereby severally represents and warrants to and agrees with the Issuers that:

(a) it has not and will not use, authorize use of, refer to, or participate in the planning for use of, any “free writing prospectus,” as defined in Rule 405 under the Act (which term includes use of any written information furnished to the Commission by the Company and not incorporated by reference into the Registration Statement and any press release issued by the Company) other than (i) a free writing prospectus that, solely as a result of use by such underwriter, would not trigger an obligation to file such free writing prospectus with the Commission pursuant to Rule 433 (other than a free writing prospectus under clause (b) below), (ii) any Issuer Free Writing Prospectus listed on Exhibit A or prepared pursuant to Section 5(d) or Section 6(c) above or (iii) any free writing prospectus prepared by such Underwriter and approved by the Company in advance in writing (the approval thereof not being intended in itself to make such free writing prospectus an Issuer Free Writing Prospectus). Notwithstanding the foregoing, the Underwriters may use a term sheet substantially in the form of Exhibit B hereto without the consent of the Company;

-19-

(b) it will, pursuant to reasonable procedures developed in good faith, retain copies of each free writing prospectus used or referred to by it, in accordance with Rule 433 under the Act; and

(c) it is not subject to any pending proceeding under Section 8A of the Act with respect to the offering (and will promptly notify the Company if any such proceeding against it is initiated during the period referred to in Section 5(e) above).

11. Termination. This Agreement may be terminated at any time prior to the Closing Date by the Representative by written notice to the Issuers if any of the following has occurred: (i) since the respective dates as of which information is given in the Registration Statement, the Time of Sale Information and the Prospectus, any material adverse change or development involving a prospective material adverse change in the condition, financial or otherwise, of the Company and its subsidiaries or the earnings, affairs, or business prospects of the Company and its subsidiaries taken as a whole, whether or not arising in the ordinary course of business, (ii) any outbreak or escalation of hostilities or other national or international calamity or crisis or change in economic conditions or in the financial markets of the United States or elsewhere that, in your judgment, is material and adverse, (iii)(a) the suspension or limitation of trading in securities of any Issuer by the Commission or on the New York Stock Exchange, or (b) the suspension or material limitation of trading in securities on the New York Stock Exchange or the Nasdaq Stock Market, Inc. or limitation on prices for securities on any such exchange, (iv) the enactment, publication, decree or other promulgation of any federal or state statute, regulation, rule or order of any court or other governmental authority which in your opinion materially and adversely affects, or will materially and adversely affect, the business or operations of the Company and its subsidiaries taken as a whole, (v) the declaration of a banking moratorium by either federal or New York State authorities, or (vi) the taking of any action by any federal, state or local government or agency in respect of its monetary or fiscal affairs which in your opinion has a material adverse effect on the financial markets in the United States and, in the case of clause (i), (ii), (iv) or (vi), that would, in the judgment of the Representative, make it impracticable to market the Securities on the terms and in the manner contemplated in the Time of Sale Information and the Prospectus.

12. No Fiduciary Duty. The Issuers acknowledge and agree that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Issuers with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, any Issuer or any other person. Additionally, neither the Representative nor any other Underwriter is advising any Issuer or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. Each Issuer shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to any Issuer with respect thereto. Any review by the Underwriters of any Issuer, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of any Issuer.
