     Date does not exceed the sum of (a) 50% of the Consolidated Net Income of
     the Company on a cumulative basis during the period (taken as one
     accounting period) from and including April 1, 1998 and ending on the last
     day of the Company's fiscal quarter immediately preceding the date of such
     Restricted Payment (or in the event such Consolidated Net Income shall be a
     deficit, minus 100% of such deficit), plus (b) 100% of the aggregate net

     cash proceeds of and the fair market value of Property received by the
     Company from (1) any capital contribution to the Company after June 9, 1997
     or any issue or sale after June 9, 1997 of Qualified Stock (other than to
     any Subsidiary of the Company) and (2) the issue or sale after June 9, 1997
     of any Indebtedness or other securities of the Company convertible into or
     exercisable for Qualified Stock of the Company that have been so converted
     or exercised, as the case may be, plus (c) $86.0 million, which is equal to

     Equity prior to the Issue Date, plus (d) in the case of the disposition or
     repayment of any Investment constituting a Restricted Payment made after
     the June 9, 1997, an amount (to the extent not included in the calculation
     of the Consolidated Net Income referred to in (a)) equal to the lesser of
     (x) the return of capital with respect to such Investment (including by
     dividend, distribution or sale of Capital Stock) and (y) the amount of such
     Investment that was treated as a Restricted Payment, in either case, less
     the cost of the disposition or repayment of such Investment (to the extent
     not included in the calculation of the Consolidated Net Income referred to
     in (a)), plus (e) with respect to any Unrestricted Subsidiary that is
              ----
     redesignated as a Restricted Subsidiary after June 9, 1997 in accordance
     with the definition of Unrestricted Subsidiary (so long as the designation

     Restricted Payment made after June 9, 1997 and only to the extent not
     included in the calculation of the Consolidated Net Income referred to in
     (a)), an amount equal to the lesser of (x) the proportionate interest of

     succeeding paragraph) made after June 9, 1997 through the Issue Date.

          (b)  Clauses (ii) and (iii) of paragraph (a) will not prohibit: (A)
the payment of any dividend within 60 days of its declaration if such dividend
could have been made on the date of its declaration without violation of the
provisions of this Indenture; (B) the repurchase, redemption or retirement of
any shares of Capital Stock of the Company in exchange for, or out of the net
proceeds of the substantially concurrent sale (other than to a Subsidiary of the
Company) of, other shares of Qualified Stock; and (C) the purchase, redemption
or other acquisition, cancellation or retirement for value of Capital Stock, or
options, warrants, equity appreciation rights or other rights to purchase or
acquire Capital Stock, of the Company or any Subsidiary held by officers or
employees or former officers or employees of the Company or any Subsidiary (or
their estates or beneficiaries under their estates) not to exceed $20 million in
the aggregate since the Issue Date; provided, however, that each Restricted
                                    --------  -------
Payment described in clauses (A) and (B) of this sentence shall be taken into
account for purposes of computing the aggregate amount of all Restricted
Payments pursuant to clause (iii) of paragraph (a).

          (c)  For purposes of determining the aggregate and permitted amounts
of Restricted Payments made, the amount of any guarantee of any Investment in
any Person that was initially treated as a Restricted Payment and which was
subsequently terminated or expired, net of any amounts paid by the Company or
any Restricted Subsidiary in respect of such guarantee, shall be deducted.

          (d)  In determining the "fair market value of Property" for purposes
of clause (iii) of the paragraph (a), Property other than cash, Cash Equivalents
and Marketable Securities shall be deemed to be equal in value to the "equity
value" of the Capital Stock or other securities issued in exchange therefor. The
"equity value" of such Capital Stock or other securities shall be equal to (i)
the number of shares of Common Equity issued in the transaction (or issuable
upon conversion or exercise of the Capital Stock or other securities issued in
the transaction) multiplied by the closing sale price of the Common Equity on
its principal market on the date of the transaction (less, in the case of
Capital Stock or other securities which require the payment of consideration at
the time of conversion or exercise, the aggregate consideration payable
thereupon) or (ii) if the Common Equity is not then traded on the New York Stock
Exchange, American Stock Exchange or Nasdaq National Market, or if the Capital
Stock or other securities issued in the transaction do not consist of Common
Equity (or Capital Stock or other securities convertible into or exercisable for
Common Equity), the value of such Capital Stock or other securities as
determined by a nationally recognized investment banking firm retained by the
Board of Directors of the Company.

Section 3.04. Limitations on Transactions with Affiliates.
              -------------------------------------------

          (a)  Until the Notes are rated Investment Grade by both Rating
Agencies (after which time the following covenant will no longer be in effect),
the Company will not, and will not cause or permit any Restricted Subsidiary to,
make any loan, advance, guarantee or capital contribution to, or for the benefit
of, or sell, lease, transfer or otherwise dispose of any property or assets to,
or for the benefit of, or purchase or lease any property or assets from, or
enter into or amend any contract, agreement or understanding with, or for the
benefit of, any Affiliate of the Company or any Affiliate of any of the
Company's Subsidiaries or any holder of 10% or more of the Common Equity of the
Company (including any Affiliates of such holders), in a single transaction or
series of related transactions (each, an "Affiliate Transaction"), except for
                                          ---------------------
any Affiliate Transaction the terms of which are at least as favorable as the
terms which could be obtained by the Company or such Restricted Subsidiary, as
the case may be, in a comparable transaction made on an arm's length basis with
Persons who are not such a holder, an Affiliate of such a holder or an Affiliate
of the Company or any of the Company's Subsidiaries.

          (b)  In addition, the Company will not, and will not cause or permit
any Restricted Subsidiary to, enter into an Affiliate Transaction unless (i)
with respect to any such Affiliate Transaction involving or having a value of
more than $10 million, the Company shall have (x) obtained the approval of a
majority of the Board of Directors of the Company and (y) either obtained the
approval of a majority of the Company's disinterested directors or obtained an
opinion of a qualified independent financial advisor to the effect that such
Affiliate Transaction is fair to the Company or such Restricted Subsidiary, as
the case may be, from a financial point of view and (ii) with respect to any
such Affiliate Transaction involving or having a value of more than $50 million,
the Company shall have (x) obtained the approval of a majority of the Board of
Directors of the Company and (y) delivered to the Trustee an opinion of a
qualified independent financial advisor to the effect that such Affiliate
Transaction is fair to the Company or such Restricted Subsidiary, as the case
may be, from a financial point of view.

          (c)  Notwithstanding the foregoing, an Affiliate Transaction will not
include (i) any contract, agreement or understanding with, or for the benefit
of, or plan for the benefit of employees of the Company or its Subsidiaries
generally (in their capacities as such) that has been approved by the Board of
Directors of the Company, (ii) Capital Stock issuances to directors, officers
and employees of the Company or its Subsidiaries pursuant to plans approved by
the stockholders of the Company, (iii) any Restricted Payment otherwise
permitted under Section 3.03, (iv) any transaction between or among the Company
and one or more Restricted Subsidiaries or between or among Restricted
Subsidiaries (provided, however, no such transaction shall involve any other
              --------  -------
Affiliate of the Company (other than an Unrestricted Subsidiary to the extent
the applicable amount constitutes a Restricted Payment permitted by this
Inden-

                                       28

ture)) and (v) any transaction between one or more Restricted Subsidiaries and
one or more Unrestricted Subsidiaries where all of the payments to, or other
benefits conferred upon, such Unrestricted Subsidiaries are substantially
contemporaneously dividended, or otherwise distributed or transferred without
charge, to the Company or a Restricted Subsidiary.

Section 3.05. Limitations on Dispositions of Assets.
              -------------------------------------

          Until the Notes are rated Investment Grade by both Rating Agencies
(after which time the following covenant will no longer be in effect), the
Company will not, and will not cause or permit any Restricted Subsidiary to,
make any Asset Disposition unless (x) the Company (or such Restricted
Subsidiary, as the case may be) receives consideration at the time of such Asset
Disposition at least equal to the Fair Market Value thereof, and (y) not less
than 70% of the consideration received by the Company (or such Restricted
Subsidiary, as the case may be) is in the form of cash, Cash Equivalents and
Marketable Securities.  The amount of any Indebtedness (other than any
Indebtedness subordinated to the Notes) of the Company or any Restricted
Subsidiary that is actually assumed by the transferee in such Asset Disposition
shall be deemed to be consideration required by clause (y) above for purposes of
determining the percentage of such consideration received by the Company or the
Restricted Subsidiaries.  The Net Cash Proceeds of an Asset Disposition shall,
within one year, at the Company's election, (a) be used by the Company or a
Restricted Subsidiary in the business of the construction and sale of homes
conducted by the Company and the Restricted Subsidiaries or any other business
of the Company or a Restricted Subsidiary existing at the time of such Asset
Disposition or (b) to the extent not so used, be applied to make a Net Cash
Proceeds Offer for the Notes and, if the Company or a Restricted Subsidiary
elects or is required to do so, repay, purchase or redeem any other
unsubordinated Indebtedness (on a pro rata basis if the amount available for
such repayment, purchase or redemption is less than the aggregate amount of (i)
the principal amount of the Notes tendered in such Net Cash Proceeds Offer and
(ii) the lesser of the principal amount, or accreted value, of such other
unsubordinated Indebtedness, plus, in each case accrued interest to the date of
repayment, purchase or redemption) at 100% of the principal amount or accreted
value thereof, as the case may be, plus accrued interest to the date of
repurchase or repayment.  Notwithstanding the foregoing, (A) the Company will
not be required to apply such Net Cash Proceeds to the repurchase of Notes in
accordance with clause (b) of the preceding sentence except to the extent that
such Net Cash Proceeds, together with the aggregate Net Cash Proceeds of prior
Asset Dispositions (other than those so used) which have not been applied in
accordance with this provision and as to which no prior Net Cash Proceeds Offer
shall have been made, exceed 5% of Consolidated Tangible Assets and (B) in
connection with any Asset Disposition, the Company and the Restricted
Subsidiaries will not be required to comply with the requirements of clause (y)
of the first sentence of this paragraph to the extent that the aggregate non-
cash consideration received in connection with such Asset Disposition, together
with the sum of all non-cash consideration received in connection with all prior
Asset Dispositions that has not yet been con-
<PAGE>

                                       29

verted into cash, does not exceed 5% of Consolidated Tangible Assets; provided,
                                                                      --------
however, that when any non-cash consideration is converted into cash, such cash
-------
shall constitute Net Cash Proceeds and be subject to the preceding sentence.

Section 3.06. Limitations on Liens.
              --------------------

          The Company will not, and will not cause or permit any Restricted
Subsidiary to, create, incur, assume or suffer to exist any Liens, other than
Permitted Liens, on any of its Property, or on any shares of Capital Stock or
Indebtedness of any Restricted Subsidiary, unless contemporaneously therewith or
prior thereto all payments due under this Indenture and the Notes are secured on
an equal and ratable basis with the obligation or liability so secured until
such time as such obligation or liability is no longer secured by a Lien.

Section 3.07. Limitations on Restrictions Affecting Restricted Subsidiaries.
              -------------------------------------------------------------

          The Company will not, and will not cause or permit any Restricted
Subsidiary to, create, assume or otherwise cause or suffer to exist or become
effective any consensual encumbrance or restriction (other than encumbrances or
restrictions imposed by law or by judicial or regulatory action or by provisions
of leases and other agreements that restrict the assignability thereof) on the
ability of any Restricted Subsidiary to (i) pay dividends or make any other
distributions on its Capital Stock or any other interest or participation in, or
measured by, its profits, owned by the Company or any other Restricted
Subsidiary, or pay interest on or principal of any Indebtedness owed to the
Company or any other Restricted Subsidiary, (ii) make loans or advances to the
Company or any other Restricted Subsidiary, or (iii) transfer any of its
properties or assets to the Company or any other Restricted Subsidiary, except
for (a) encumbrances or restrictions existing under or by reason of applicable
law, (b) covenants or restrictions contained in Indebtedness in effect on the
date of this Indenture as such covenants or restrictions are in effect on such
date, (c) any restrictions or encumbrances arising under Acquired Indebtedness;

provided, that such encumbrance or restriction applies only to either the assets
--------
that were subject to the restriction or encumbrance at the time of the
acquisition or the obligor on such Indebtedness and its Subsidiaries, (d) any
restrictions or encumbrances arising in connection with Refinancing
Indebtedness; provided, however, that any restrictions and encumbrances of the
              --------  -------
type described in this clause (d) that arise under such Refinancing Indebtedness
shall not be materially more restrictive than those under the agreement creating
or evidencing the Indebtedness being refunded, refinanced, replaced or extended,
(e) any Permitted Lien, or any other agreement restricting the sale or other
disposition of property, securing Indebtedness permitted by this Indenture if
such Permitted Lien or agreement does not expressly restrict the ability of a
Subsidiary of the Company to pay dividends or make or repay loans or advances
prior to default thereunder, (f) reasonable and customary borrowing base
covenants set forth in agreements evidencing Indebtedness otherwise permitted
<PAGE>

                                       30

by this Indenture, (g) customary provisions restricting subletting or assignment
of any lease governing a leasehold interest of the Company or any Restricted
Subsidiary, and (h) any restriction with respect to a Restricted Subsidiary
imposed pursuant to an agreement entered into for the sale or disposition of all
or substantially all of the Capital Stock or assets of such Restricted
Subsidiary pending the closing of such sale or disposition.

Section 3.08. Limitations on Mergers, Consolidations and Sales of Assets.
              ----------------------------------------------------------

          Neither the Company nor any Guarantor will consolidate or merge with
or into, or sell, lease, convey or otherwise dispose of all or substantially all
of its assets (including, without limitation, by way of liquidation or
dissolution), or assign any of its obligations under the Notes, the Guarantees
or this Indenture (as an entirety or substantially in one transaction or in a
series of related transactions), to any Person (in each case other than in a
transaction in which the Company or a Restricted Subsidiary is the survivor of a
consolidation or merger, or the transferee in a sale, lease, conveyance or other
disposition) unless: (i) the Person formed by or surviving such consolidation or
merger (if other than the Company or the Guarantor, as the case may be), or to
which such sale, lease, conveyance or other disposition or assignment will be
made (collectively, the "Successor"), is a corporation or other legal entity
                         ---------
organized and existing under the laws of the United States or any state thereof
or the District of Columbia, and the Successor assumes by supplemental indenture
in a form reasonably satisfactory to the Trustee all of the obligations of the
Company or the Guarantor, as the case may be, under the Notes or a Guarantee, as
the case may be, and the Indenture, (ii) immediately after giving effect to such
transaction, no Default or Event of Default has occurred and is continuing,
(iii) immediately after giving effect to such transaction and the use of any net
proceeds therefrom, on a pro forma basis, the Consolidated Net Worth of the
                         --- -----
Company or the Successor (in the case of a transaction involving the Company),
as the case may be, would be at least equal to the Consolidated Net Worth of the
Company immediately prior to such transaction (exclusive of any adjustments to
Consolidated Net Worth attributable to transaction costs) less any amount
treated as a Restricted Payment in connection with such transaction in
accordance with this Indenture and (iv)  unless prior to such transaction the
Notes are rated Investment Grade by both Rating Agencies (after which this
clause (iv) shall not apply), immediately after giving effect to such
transaction, the Company could incur at least $1.00 of Indebtedness pursuant to
Section 3.02(a) hereof.  The foregoing provisions shall not apply to (i) a
transaction involving the sale or disposition of Capital Stock of a Guarantor,
or the consolidation or merger of a Guarantor, or the sale, lease, conveyance or
other disposition of all or substantially all of the assets of a Guarantor, that
in any such case results in such Guarantor being released from its Guarantee
pursuant to the Indenture or (ii) a transaction the purpose of which is to
change the state of incorporation of the Company or any Guarantor.

Section 3.09. Reports to Holders of Notes.
              ---------------------------

          The Company will file with the Commission the annual reports and the
information, documents and other reports required to be filed pursuant to
Section 13 or 15(d) of the Exchange Act.  The Company will file with the Trustee
and mail to each Holder of record of Notes such reports, information and
documents within 15 days after it files them with the Commission.  In the event
that the Company is no longer subject to these periodic requirements of the
Exchange Act, it will nonetheless continue to file reports with the Commission
and the Trustee and mail such reports to each Holder of Notes as if it were
subject to such reporting requirements.  Regardless of whether the Company is
required to furnish such reports to its stockholders pursuant to the Exchange
Act, the Company will cause its consolidated financial statements and a
"Management's Discussion and Analysis of Results of Operations and Financial
Condition" written report, similar to those that would have been required to
appear in annual or quarterly reports, to be delivered to Holders of Notes.

1.   Interest.
     --------

          D.R. HORTON, INC. (the "Company"), a Delaware corporation, promises to
pay interest on the principal amount of this Security at the rate per annum
shown above.  The Company will pay interest semiannually on August 15 and
February 15 of each year, commencing February 15, 2002, 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 the date of original issuance, 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.

2.   Method of Payment.
     -----------------

          The Company 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 Company) to the
persons who are registered Holders of Securities at the close of business on the
August 1 and February 1 immediately preceding the interest payment date.
Holders must surrender Securities to a Paying Agent to collect principal
payments.  The Company 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.

3.   Paying Agent and Registrar.
     --------------------------

          Initially, American Stock Transfer & Trust Company (the "Trustee")
will act as Paying Agent and Registrar.  The Company may change or appoint any
Paying Agent, Registrar or co-Registrar without notice.  The Company or any of
its Subsidiaries or any of their Affiliates may act as Paying Agent, Registrar
or co-registrar.

4.   Indenture.
     ---------

          The Company issued the Securities under an Indenture dated as of June
9, 1997 among the Company, the Guarantors and the Trustee, as supplemented (the
"Indenture").  The terms of the Securities and the Guarantees include those
stated in the Indenture 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 Guarantees are subject to all such terms, and Holders are
referred to the Indenture and the Act for a statement of them.  Capitalized
terms not defined herein have the meanings given to those terms in the
Indenture.

                                      A-3
<PAGE>

          The Company will furnish to any Holder upon written request and
without charge a copy of the Indenture and the applicable Authorizing Resolution
or supplemental indenture.  Requests may be made to:  D.R. Horton, Inc., 1901
Ascension Blvd., Suite 100, Arlington, Texas 76006, Attention:  Chief Financial
Officer.

5.   Redemption.
     ----------

          Except as set forth in the following sentence, the Securities will not
be redeemable.  The Company may redeem Securities, at any time on or before
August 15, 2004, with the net cash proceeds of one or more Public Equity
Offerings by the Company, at a redemption price equal to 107.875% of the
principal amount of such Securities, plus accrued and unpaid interest, if any,
to the date of redemption; provided, however, that at least 65% of the aggregate
                           --------  -------
principal amount of Securities, excluding any Securities held by the Company or
any of its Affiliates, remains outstanding immediately after the occurrence of
such redemption.  Notice of any such redemption must be given within 60 days
after the date of the closing of the relevant Public Equity Offering.

          Notice of redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each Holder of Securities to be redeemed
at his registered address.  Securities in denominations larger than $1,000 may
be redeemed in part.  On and after the redemption date interest ceases to accrue
on Securities or portions of them called for redemption, provided that if the
Company shall default in the payment of such Security at the redemption price
together with accrued interest, interest shall continue to accrue at the rate
borne by the Securities.

6.   Denominations, Transfer, Exchange.
     ---------------------------------

          The Securities are in registered form only without coupons in
denominations of $1,000 and integral multiples of $1,000.  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.

7.   Persons Deemed Owners.
     ---------------------

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

                                      A-4
<PAGE>

8.   Unclaimed Money.
     ---------------

          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
Company at its request.  After that, Holders entitled to the money must look to
the Company for payment unless an abandoned property law designates another
person.

9.   Amendment, Supplement, Waiver.
     -----------------------------

          Subject to certain exceptions, the Indenture or the Securities may be
amended or supplemented 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
Company and the Trustee may amend or supplement the Indenture or the Securities
to cure any ambiguity, defect or inconsistency, 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 which, in accordance with
the terms of the Indenture, ceases to be liable in respect of its Guarantee, or
to make any other change, provided such action does not adversely affect the
rights of any Holder.

10.  Successor Corporation.
     ---------------------

          When a successor corporation assumes all the obligations of its
predecessor under the Securities and the Indenture, the predecessor corporation
will be released from those obligations.

Indenture, in its individual or any other capacity, may make loans to, accept
deposits from, and perform services for the Company or its affiliates, and may
otherwise deal with the Company or its affiliates, as if it were not Trustee.

12.  No Recourse Against Others.
     --------------------------

          A director, officer, employee or stockholder, as such, of the Company
shall not have any liability for any obligations of the Company under the
Securities or the Indenture or for any claim based on, in respect of or by
reason of, such obligations or their creation.  Each Holder by accepting a
Security waives and releases all such liability.  The waiver and release are
part of the consideration for the issue of the Securities.

                                   GUARANTEE

          The undersigned (the "Guarantors") have unconditionally guaranteed,

as the "Guarantee") (i) the due and punctual payment of the principal of and
interest on the Securities, whether at maturity, by acceleration or otherwise,
