                                      -2-

                                  ARTICLE ONE

                   Scope of Supplemental Indenture; General

          The changes, modifications and supplements to the Indenture effected
by this Supplemental Indenture shall be applicable only with respect to, and
govern the terms of, the Notes, which shall be limited in aggregate principal
amount to $250.0 million in one or more series, and shall not apply to any other
Securities that may be issued under the Indenture unless a supplemental
indenture with respect to such other Securities specifically incorporates such
changes, modifications and supplements. Pursuant to this Supplemental Indenture,
there is hereby created and designated a series of Securities under the
Indenture entitled "9.375% Senior Subordinated Notes due 2011." The Notes shall
be in the form of Exhibit A hereto. The Notes shall be guaranteed by the
                  ---------
Guarantors as provided in such form and the Indenture. If required, the Notes
may bear an appropriate legend regarding original issue discount for federal
income tax purposes.

          In the event that the Company shall issue and the Trustee shall
authenticate any Notes issued under this Supplemental Indenture subsequent to
the Issue Date (such Notes, "Additional Securities"), the Company shall use its
                             ---------------------
best efforts to obtain the same "CUSIP" number for such Notes as is printed on
the Notes outstanding at such time; provided, however, that if any series of
                                    --------  -------
Notes issued under this Supplemental Indenture subsequent to the Issue Date is
determined, pursuant to an Opinion of Counsel of the Company in a form
reasonably satisfactory to the Trustee, to be a different class of security than
the Notes outstanding at such time for federal income tax purposes, the Company
may obtain a "CUSIP" number for such Notes that is different than the "CUSIP"
number printed on the Notes then outstanding. Notwithstanding the foregoing, all
Notes issued under this Supplemental Indenture shall vote and consent together
on all matters as one class and no series of Notes will have the right to vote
or consent as a separate class on any matter.

          In the event that less than all of the Notes are to be redeemed at any
time pursuant to an optional redemption, selection of the Notes for redemption
will be made by the Trustee in compliance with the requirements of the principal
national securities exchange, if any, on which the Notes are listed or, if the
Notes are not then listed on a national security exchange, on a pro rata basis,
by lot or by such method as the Trustee shall deem fair and appropriate. In
addition, if a partial redemption is made pursuant to paragraph 5(b) of the
Notes, selection of the Notes or portions thereof for redemption shall be made
by the Trustee only on a pro rata basis or on as nearly a optional redemption
basis as is practicable (subject to the procedures of the Depository Trust
Company), unless that method is otherwise prohibited.

Transaction Date; and (2) notwithstanding clause (1) above, interest on such
Indebtedness determined on a fluctuating basis, to the extent such interest is
covered by agreements relating to Interest Protection Agreements, shall be

           -----------------------
designated by a resolution adopted by the Board of Directors of the Company or a
duly authorized committee thereof as provided below; provided that (a) the
                                                     --------
holders of Indebtedness thereof do not have direct or indirect recourse against
the Company or any Restricted Subsidiary, and neither the Company nor any
Restricted Subsidiary otherwise has liability for, any payment obligations in
respect of such Indebtedness (including any undertaking, agreement or instrument
evidencing such Indebtedness), except, (i) in each case, to the extent that the
amount thereof constitutes a Restricted Payment permitted by the Indenture, (ii)
in the case of Non-Recourse Indebtedness, to the extent such recourse or
liability is for the matters discussed in the last sentence of the definition of
"Non-Recourse Indebtedness," or (iii) to the extent such Indebtedness is a
guarantee by such Subsidiary of Indebtedness of the Company or a Restricted
Subsidiary and (b) no holder of any Indebtedness of such Subsidiary shall have a
right to declare a default on such Indebtedness or cause the payment thereof to
be accelerated or payable prior to its stated maturity as a result of a default
on any Indebtedness of the Company or any Restricted Subsidiary. Subject to the
foregoing, the Board of Directors of the Company or a duly authorized committee
thereof may designate any Subsidiary to be an Unrestricted Subsidiary;

provided, however, that (i) the net amount (the "Designation Amount") then
--------  -------                                ------------------
outstanding of all previous Investments by the Company and the Restricted

time of such designation and will reduce the amount available for Restricted
Payments under Section 3.04 hereof, to the extent provided therein, (ii) the
Company must be permitted under Section 3.04 hereof to make the Restricted
Payment deemed to have been made pursuant to clause (i), and (iii) after giving

incur $1.00 of additional Indebtedness under Section 3.02(a) hereof.  Any such
designation or redesignation by the Board of Directors of the Company or a
committee thereof will be evidenced to the Trustee by the filing with the

Company or a committee thereof giving effect to such designation or
redesignation and an Officers' Certificate certifying that such designation or
redesignation complied with the foregoing conditions and setting forth the
underlying calculations of such Officers' Certificate.  The designation of any
Person as an Unrestricted Subsidiary shall be deemed to include a designation of
all Subsidiaries of such Person as Unrestricted Subsidiaries; provided, however,
                                                              --------  -------
that the ownership of the general partnership interest (or a similar member's
interest in a limited liability company) by an Unrestricted Subsidiary shall not

Unrestricted Subsidiary.

Section 3.01.  Repurchase of Notes upon Change of Control.
               ------------------------------------------

               (a)  In the event that there shall occur a Change of Control,
each Holder of Notes shall have the right, at such Holder's option, to require
the Company to purchase all or any part of such Holder's Notes on a date (the
"Repurchase Date") that is no later than 90 days after notice of the Change of
 ---------------
Control, at 101% of the principal amount thereof plus accrued interest to the
Repurchase Date.

               (b)  On or before the thirtieth day after any Change of Control,
the Company is obligated to mail, or cause to be mailed, to all Holders of
record of Notes a notice regarding the Change of Control and the repurchase
right. The notice shall state the Repurchase Date, the date by which the
repurchase right must be exercised, the price for the Notes and the procedure
which the Holder must follow to exercise such right. Substantially
simultaneously with mailing of the notice, the Company shall cause a copy of
such notice to be published in a newspaper of general circulation in the Borough
of Manhattan, The City of New York. To exercise such right, the Holder of such
Note must deliver at least ten days prior to the Repurchase Date written notice
to the Company (or an agent designated by the Company for such purpose) of the
Holder's exercise of such right, together with the Note with respect to which
the right is being exercised, duly endorsed for transfer; provided, however,
                                                          --------  -------
that if mandated by applicable law, a Holder may be permitted to deliver such
written notice nearer to the Repurchase Date than may be specified by the
Company.

               (c)  The Company will comply with applicable law, including
Section 14(e) of the Exchange Act and Rule 14e-1 thereunder, if applicable, if
the Company is required to give a notice of right of repurchase as a result of a
Change of Control.

Section 3.02.  Limitations on Indebtedness.
               ---------------------------

               (a)  Until the Notes are rated Investment Grade by both Rating
Agencies (after which time this Section 3.02 will no longer be in effect), the
Company will not, and will not cause or permit any Restricted Subsidiary,
directly or indirectly, to, create, incur, assume, become liable for or
guarantee the payment of (collectively, an "incurrence") any Indebtedness
                                            ----------
(including Acquired Indebtedness) unless, after giving effect thereto and the
application of the proceeds therefrom, the Consolidated Fixed Charge Coverage
Ratio on the date thereof would be at least 2.0 to 1.0.

               (b)  Notwithstanding the foregoing, this Section 3.02 will not
prevent the incurrence of: (i) Permitted Indebtedness, (ii) Refinancing
Indebtedness, (iii) Non-Recourse Indebtedness, (iv) any Guarantee of
Indebtedness of the Company represented by the Notes and
<PAGE>

                                     -21-

(v) any guarantee of Indebtedness incurred under Credit Facilities in compliance
with this Indenture.

               (c)  For purposes of determining compliance with this Section
3.02, in the event that an item of Indebtedness may be incurred through the
first paragraph of this covenant or by meeting the criteria of one or more of
the types of Indebtedness described in the second paragraph of this covenant (or
the definitions of the terms used therein), the Company, in its sole discretion,
(i) may classify such item of Indebtedness under and comply with either of such
paragraphs (or any of such definitions), as applicable, (ii) may classify and
divide such item of Indebtedness into more than one of such paragraphs (or
definitions), as applicable, and (iii) may elect to comply with such paragraphs
(or definitions), as applicable, in any order.

Section 3.03.  Limitation on Senior Subordinated Indebtedness.
               ----------------------------------------------

               The Company will not, and will not cause or permit any Guarantor
to, directly or indirectly, incur any Indebtedness that purports by its terms
(or by the terms of any agreement governing such Indebtedness) to rank senior in
right of payment to the Notes and subordinated in right of payment to any other
Indebtedness of the Company or of such Guarantor, as the case may be.

Section 3.04.  Limitation on Restricted Payments.
               ---------------------------------

               Until the Notes are rated Investment Grade by both Rating
Agencies (after which time this Section 3.04 will no longer be in effect)

               (a)  the Company will not, and will not cause or permit any
Restricted Subsidiary to, directly or indirectly, make any Restricted Payment
unless:

                (i) no Default or Event of Default shall have occurred and be
     continuing at the time of or immediately after giving effect to such
     Restricted Payment;

               (ii) immediately after giving effect to such Restricted Payment,
     the Company could incur at least $1.00 of Indebtedness pursuant to Section
     3.02(a); and

              (iii) immediately after giving effect to such Restricted Payment,
     the aggregate amount of all Restricted Payments (including the Fair Market
     Value of any non-cash Restricted Payment) declared or made after the Issue
     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 pro-
<PAGE>

                                     -22-

     ceeds 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
     the aggregate principal amount of the Company's 6 7/8% Convertible
     Subordinated Notes due 2002 that were converted into the Company's Common
     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
     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
     of such Subsidiary as an Unrestricted Subsidiary was treated as a
     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
     the Company or a Restricted Subsidiary in an amount equal to the excess of
     (I) the total assets of such Subsidiary, valued on an aggregate basis at
     the lesser of book value and Fair Market Value thereof, over (II) the total
     liabilities of such Subsidiary, determined in accordance with GAAP, and (y)
     the Designation Amount at the time of such Subsidiary's designation as an
     Unrestricted Subsidiary, plus (f) $50.0 million minus (g) the aggregate
     amount of all Restricted Payments (other than Restricted Payments referred
     to in clause (C) of (b) below) made after June 9, 1997 through the Issue
     Date.

               (b)  Clauses (ii) and (iii) of (a) above 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
<PAGE>

                                     -23-

computing the aggregate amount of all Restricted Payments pursuant to clause
(iii) of (a) above.

               (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 (a) above, 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 does 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 3.05.  Limitations on Transactions with Affiliates.
               --------------------------------------------

               Until the Notes are rated Investment Grade by both Rating
Agencies (after which time this Section 3.05 will no longer be in effect),

               (a)  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.
<PAGE>

                                     -24-

               (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 $50.0 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 (a) and (b) above , 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 3.04, (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 Indenture)) 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 3.06.  Limitations on Dispositions of Assets.
               -------------------------------------

               Until the Notes are rated Investment Grade by both Rating
Agencies (after which time this Section 3.06 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
<PAGE>

                                     -25-

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 repay,
purchase or redeem Senior Indebtedness and/or Guarantor Senior Indebtedness or
(c) to the extent not used pursuant to clauses (a) and (b), 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
Indebtedness that ranks pari passu with the Notes (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 pari passu 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) or (c) 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 Section 3.06 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
converted 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 3.07.  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 the Indenture and the Notes and/or the
Guarantees, as the case may be, are secured (i) in the case of an obligation
that ranks pari passu with the Notes or a Guarantee, on at least an equal and
ratable basis with the obligation so secured and (ii) in the case of an
obligation that is subordinated to the
<PAGE>

                                     -26-

Notes or a Guarantee, on a basis that is senior in priority to the Lien securing
such obligation, in each case, until such time as such obligation is no longer
secured by a Lien.

Section 3.08.  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

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

and customary borrowing base covenants set forth in agreements evidencing
Indebtedness otherwise permitted by this Indenture, (g) customary provisions

Section 3.09.  Limitations on Mergers, Consolidations and Sales of Assets.
               ----------------------------------------------------------

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

                                     -27-

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

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). 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 3.10.  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.

                              (the "Securities")

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 March 15 and
September 15 of each year, commencing September 15, 2001, 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
March 1 and September 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 may act as Paying Agent, Registrar or co-Registrar.

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

          The Company issued the Securities under an Indenture dated as of
September 11, 2000 ("Indenture") among the Company, the Guarantors and the
Trustee, as supplemented by a Second Supplemental Indenture dated as of March
12, 2001. The terms of the Securities and the Guarantees include those stated in
the Indenture and those made part of the

                                      A-4
<PAGE>

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 Securityholders 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.

          The Company will furnish to any Securityholder 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,

On and after the redemption date, interest ceases to accrue on Securities or

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

          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.

10.  Amendment, Supplement, Waiver.
     -----------------------------

          Subject to certain exceptions, the Indenture, the Securities or the
Guarantees may be amended or supplemented with the consent (which may include
consents obtained in connection with a tender offer or exchange offer for
Securities) of the Holders of at least a majority in principal amount of the
outstanding Securities then outstanding and any existing default under, or
compliance with any provision of the Indenture relating to the Securities may be
waived (other than any continuing Default or Event of Default in the payment of
interest on or the principal of the Securities) with the consent (which may
include consents obtained in connection with a tender offer or exchange offer
for Securities) of the Holders of a majority
<PAGE>

in principal amount of the Securities then outstanding. Without the consent of
any Securityholder, the Company and the Trustee may amend or supplement the
Indenture, the Securities or the Guarantees 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

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 Securityholder.

13.  No Recourse Against Others.
     --------------------------

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 Securityholder 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,
the due and punctual payment of interest on the overdue principal and interest,
if any, on the Securities, to the extent lawful, and the due and punctual
performance of all other obligations of the Company to the Holders or the
Trustee all in accordance with the terms set forth in Article Nine of the
Indenture and (ii) in case of any extension of time of payment or renewal of any

the Guarantee by reason of such person's status as stockholder, officer,

Security waives and releases all such liability. This waiver and release are
part of the consideration for the issuance of the Guarantees.

Guarantor named below shall have no further liability with respect to its
Guarantee if such Guarantor otherwise ceases to be liable in respect of its
Guarantee in accordance with the terms of the Indenture.

the certificate of authentication on the Securities upon which the Guarantee is
noted shall have been executed by the Trustee under the Indenture by the manual
