Dear Sirs:

         Del Webb Corporation (the "Company") proposes to issue and sell to
Warburg Dillon Read LLC, Goldman, Sachs & Co., Salomon Smith Barney Inc. and
NationsBanc Montgomery Securities LLC (the "Underwriters") $150,000,000
aggregate principal amount of its 10-1/4% Senior Subordinated Debentures due
2010, (the "Debentures"). The Debentures are described in the Prospectus which
is referred to below.

         The Debentures are to be issued pursuant to an Indenture (the
"Indenture") to be dated as of February 18, 1999, between the Company and Bank
of Montreal Trust Company, as trustee.

         The Company has filed, in accordance with the provisions of the
Securities Act of 1933, as amended, and the rules and regulations thereunder
(collectively, the "Act"), with the Securities and Exchange Commission (the
"Commission") a shelf registration statement on Form S-3, including a
prospectus, relating to $250,000,000 of securities, including the Debentures,
which incorporates by reference documents that the Company has filed or will
file in accordance with the provisions of the Securities Exchange Act of 1934,
as amended, and the rules and regulations thereunder (collectively, the
"Exchange Act"). As used in this Agreement, "Base Prospectus" shall mean the
prospectus included in the Registration Statement when it became effective under
the Act on October 22, 1998, as it may have been amended subsequent to that date
and prior to the date hereof. The Company has furnished to you, for use by you
and by dealers, copies of a preliminary prospectus supplement, including the
Base Prospectus contained therein and all documents incorporated by reference
therein (collectively, the "Preliminary Prospectus") relating to the Debentures.
Except where the context otherwise requires, the shelf registration
<PAGE>   3
statement, as in effect at the time of execution of this Agreement, including
all documents filed as part thereof or incorporated by reference therein, and
including the Base Prospectus, is herein called the "Registration Statement,"
and the final prospectus supplement relating to the Debentures, including (i)
the Base Prospectus and (ii) all documents incorporated therein or in the Base
Prospectus by reference, in the form first filed by the Company with the
Commission pursuant to Rule 424(b)(5) under the Act, is herein called the
"Prospectus."

         The Company and the Underwriters agree as follows:

         1. Sale and Purchase: Upon the basis of the warranties and
representations and the other terms and conditions herein set forth, the Company
agrees to sell to the Underwriters and the Underwriters, severally and not
jointly, agree to purchase from the Company, the aggregate principal amount of
Debentures set forth opposite the name of such Underwriter in Schedule I
attached hereto, in each case at a purchase price of 98.390% of the principal
amount thereof, plus accrued interest from the Time of Purchase (as hereinafter
defined). You shall release the Debentures for public sale promptly after this
Agreement becomes effective. You may from time to time increase or decrease the
public offering price after the initial public offering to such extent as you
may determine.

         2. Payment and Delivery: Payment of the purchase price for the
Debentures shall be made to the Company in immediately available funds at the
office of Warburg Dillon Read LLC in New York City, against delivery of the
Debentures to you for the respective accounts of the Underwriters. Such payment
and delivery shall be made at 10:00 A.M., New York City time, on February 18,
1999 (unless another time shall be agreed to by you and the Company or unless
postponed in accordance with the provisions of Section 8 hereof). The time at
which such payment and delivery are actually made is hereinafter sometimes
called the "Time of Purchase." The Debentures shall be delivered to you in
definitive or global form in such names and in such denominations as you shall
specify on the second business day(1) preceding the Time of Purchase. For the
purpose of expediting the checking of the Debentures by you, the Company agrees
to make such Debentures available to you for such purpose at least one full
business day preceding the Time of Purchase.

         3. Representations and Warranties of the Company: The Company
represents and warrants to the Underwriters that:


- --------
(1)      As used herein, "business day" shall mean a day on which the New York
         Stock Exchange is open for trading.

         Registration Statement became effective and at all times subsequent
         thereto up to the Time of Purchase, the Registration Statement and the
         Prospectus, and any supplements or amendments thereto, complied and
         will comply in all material respects with the provisions of the Act and
         the Trust Indenture Act of 1939, as amended (the "Trust Indenture
         Act"), and the Registration Statement at all such times did not and
         will not contain an untrue statement of a material fact or omit to
         state a material fact required to be stated therein or necessary to

         Prospectus entitled "Underwriting;" the documents incorporated by
         reference in the Prospectus, at the time they were filed (or, if an
         amendment with respect to any such document was filed, when such
         amendment was filed) with the Commission, complied in all material
         respects with the requirements of the Exchange Act, and, except to the
         extent, if any, they are modified or superseded by the Registration
         Statement or the Prospectus, do not contain an untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein or necessary to make the statements therein, in light of the
         circumstances under which they were made, not misleading; and the
         Company has complied and, until completion of the offering of the
         Debentures will continue in the future to comply, with its obligations
         under the Exchange Act;

                  (b) the conditions for use of a registration statement on Form

         made and proposed to be made of such property by the Company and its

         holds its material leased properties, if any, under valid and binding
         leases, with such exceptions as are not materially significant in

         provided for on the books of the Company and its subsidiaries;

                  (v) the Company has not incurred any liability for any

         "investment company" within the meaning of the Investment Company Act
         of 1940, as amended, or is subject to regulation thereunder.

         circumstances under which they are made, not misleading, and, during
         such time, to prepare and furnish, at the Company's expense, to you
         promptly such amendments or supplements to such Prospectus as may be
         necessary to reflect any such change in such quantities as reasonably
         requested by you and to furnish to you a copy of such proposed

<PAGE>   16
         If you elect to terminate this Agreement as provided in this Section 7,
the Company and the other Underwriters shall be notified promptly by letter sent
by facsimile transmission and registered mail, or by telegram.

         If the sale to the Underwriters of the Debentures, as contemplated by

         all Underwriters so defaulting shall have agreed but failed to take up
         and pay for does not exceed 10% of the total aggregate principal amount
         of the Debentures, the non-defaulting Underwriter or Underwriters shall
         take up and pay for (in addition to the aggregate principal amount of
         the Debentures it is obliged to purchase pursuant to Section 1 hereof)
         the aggregate principal amount of the Debentures agreed to be purchased
         by such defaulting Underwriter, as hereinafter provided. Such aggregate
         principal amount of the Debentures shall be taken up and paid for by
         such non-defaulting Underwriter or Underwriters in such amounts as you
         may designate with the consent of each Underwriter so designated or, in
         the event no such designation is made, such aggregate principal amount
         of the Debentures shall be taken up and paid for by all nondefaulting
         Underwriters pro rata in proportion to the aggregate principal amount
         of the Debentures set forth opposite the names of such non-defaulting

         all Underwriters so defaulting shall have agreed but failed to take up

         Debentures, the non-defaulting Underwriter or Underwriters may, but
         shall not be required to, elect to take up and pay for the aggregate
         principal amount of the Debentures agreed to be purchased by such
         defaulting Underwriter or Underwriters in such amounts as you may
         designate with the consent of each Underwriter so
<PAGE>   17
         designated. If the non-defaulting Underwriters do not so elect, this
         Agreement shall terminate without liability on the part of any
         non-defaulting Underwriter.

         Without relieving any defaulting Underwriter from its obligations
hereunder, the Company agrees with the non-defaulting Underwriter or
Underwriters that it will not sell any Debentures hereunder unless all of the
Debentures are purchased by the Underwriters (or by substituted Underwriters
selected by you with the approval of the Company (which will not be unreasonably
withheld) or selected by the Company with your approval).

         If a new Underwriter or Underwriters are substituted by the
non-defaulting Underwriter or Underwriters or by the Company for a defaulting
Underwriter or Underwriters in accordance with the foregoing provisions, the
Company or you shall have the right to postpone the Time of Purchase for a
period not exceeding five (5) business days in order that any necessary changes
in the Registration Statement and Prospectus and other documents may be
effected.

         The term Underwriter as used in this Agreement shall refer to and
include any Underwriter substituted under this Section 8 with like effect as if
such substituted Underwriter had originally been named in Schedule I.

         9.       Indemnity by the Company and the Underwriters:

                  (a) The Company agrees to indemnify and hold harmless each of
         the Underwriters, each person that controls any of the Underwriters
         within the meaning of Section 15 of the Act or Section 20 of the
         Exchange Act, and the agents, employees, officers and directors of each
         of the Underwriters and of each such controlling person (collectively,
         the "Underwriter indemnified parties") from and against any and all
         losses, claims, damages, judgments, liabilities and expenses
         (including, but not limited to, the reasonable fees and expenses of
         counsel and other expenses in connection with investigating, preparing,
         defending or settling any such action or claim, whether commenced or
         threatened) which, jointly or severally, any Underwriter indemnified
         party may incur as they are incurred (and regardless of whether the
         Underwriter indemnified party is a party to the litigation, if any)
         arising out of or based upon any untrue statement or alleged untrue
         statement of a material fact contained in the Registration Statement or
         the Prospectus or the Preliminary Prospectus (as the same may have been
         or may be amended or supplemented), or arising out of or based upon any
         omission or alleged
<PAGE>   18
         omission to state therein a material fact required to be stated therein
         or necessary to make the statements therein not misleading, except
         insofar as such losses, claims, damages, judgments, liabilities or
         expenses arise out of, or are based upon, any such untrue statement or
         omission or alleged untrue statement or omission based upon and in
         conformity with information with respect to the Underwriters furnished
         in writing by you to the Company expressly for use therein with
         reference to the Underwriters; provided, however, that the indemnity
         agreement contained in this Section 9(a) with respect to the
         Preliminary Prospectus or amended or supplemented Preliminary
         Prospectus shall not inure to the benefit of any of the Underwriters
         (or to the benefit of any person controlling any of the Underwriters)
         from whom the person asserting any such loss, expense, liability or
         claim purchased the Debentures which is the subject thereof if the
         Prospectus corrected any such alleged untrue statement or omission and
         if such Underwriter failed to send or give a copy of the Prospectus to
         such person at or prior to the written confirmation of the sale of such
         Debentures to such person.

                  (b) If any action or proceeding (including any governmental or
         regulatory investigation or proceeding) shall be brought or asserted
         against any Underwriter indemnified party, with respect to which
         indemnity may be sought against the Company pursuant to this Section 9,
         such Underwriter indemnified party shall promptly notify the Company in
         writing, and the Company shall assume the defense thereof, including
         the employment of counsel satisfactory to the Underwriter indemnified
         party in its reasonable judgment and payment of all fees and expenses;
         provided that the omission so to notify the Company shall not relieve
         the Company from any liability that it may have to any Underwriter
         indemnified party unless, and only to the extent that, such omission
         results in the forfeiture of substantive rights or defenses by the
         Company. An Underwriter indemnified party shall have the right to
         employ separate counsel in any such action or proceeding and to assume
         in the defense thereof, but the fees and expenses of such counsel shall
         be at the expense of such Underwriter indemnified party unless (i) the
         employment of such counsel has been specifically authorized in writing
         by the Company, (ii) the Company has failed promptly to assume the
         defense and employ counsel satisfactory to the Underwriter indemnified
         party in its reasonable judgment, or (iii) the named parties to any
         such action or proceeding (including any impleaded parties) include
         both the Underwriter indemnified party and the Company and such
         Underwriter indemnified party shall have concluded in its reasonable
         judgment that there may be one or more legal defenses available to it
         that are different from or additional to those available to the Company
         (in which case the Company shall not have the right to assume the
         defense of such action on behalf of such Underwriter indemnified
         party), in any of which events such fees and expenses shall be borne by
         the Company and paid as
<PAGE>   19
         incurred. It is understood, however, that the Company 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
         reasonable fees and expenses of more than one separate firm of
         attorneys (in addition to any local counsel) at any time for all such
         Underwriter indemnified parties, which firm shall be designated in
         writing by Warburg Dillon Read LLC, and that all such fees and expenses
         shall be reimbursed as they are incurred. The Company shall not be
         liable for any settlement of any such action effected without the
         written consent of the Company (which consent shall not be unreasonably
         withheld or delayed), but if settled with the written consent of the
         Company, or if there is a final judgment with respect thereto, the
         Company agrees to indemnify and hold harmless each Underwriter
         indemnified party from and against any loss or liability by reason of
         such settlement or judgment.

                  (c) Each Underwriter, severally and not jointly, agrees to
         indemnify and hold harmless the Company, its directors, its officers
         who signed the Registration Statement, and any person that controls the
         Company within the meaning of Section 15 of the Act or Section 20 of
         the Exchange Act (collectively, the "Company indemnified parties") to
         the same extent as the foregoing indemnity from the Company to the
         Underwriter indemnified parties, but only with respect to information
         covering such Underwriter furnished in writing by or on behalf of such
         Underwriter through you to the Company expressly for use with respect
         to such Underwriter in the Registration Statement, the Prospectus or
         the Preliminary Prospectus (as the same may have been amended or
         supplemented). In case any action shall be brought against any Company
         indemnified party based on the Registration Statement, the Prospectus
         or the Preliminary Prospectus (as the same may have been amended or
         supplemented) and in respect of which indemnity may be sought against
         the Underwriters pursuant to this Section 9(c), the Underwriters shall
         have the rights and duties given to the Company by Section 9(b) hereof
         (except that if the Company shall have assumed the defense thereof the
         Underwriters shall not be required to do so, but may employ separate
         counsel therein and participate in the defense thereof, provided that
         the fees and expenses of such counsel shall be at the Underwriters'
         expense), and the Company indemnified parties shall have the rights and
         duties given to the Underwriter indemnified parties by Section 9(b)
         hereof.

                  (d) If the indemnification provided for in this Section 9 is
<PAGE>   20
         unavailable to, or insufficient to hold harmless, any Underwriter
         indemnified party or any Company indemnified party, then the party
         required to indemnify such indemnified party under this Section 9
         shall, in lieu of indemnifying such indemnified party, contribute to
         the amount paid or payable by such indemnified party as a result of
         such losses, claims, damages, judgments, liabilities and expenses (i)
         in such proportion as is appropriate to reflect the relative benefits
         received by the Company on the one hand and the Underwriters on the
         other from the offering of the Debentures, or (ii) if the allocation
         provided by clause (i) above is not permitted by applicable law, in
         such proportion as is appropriate to reflect not only the relative
         benefits referred to in clause (i) above but also the relative fault of
         the Company on the one hand and the Underwriters on the other in
         connection with the statements or omissions which resulted in such
         losses, claims, damages, liabilities or expenses, as well as any other
         relevant equitable considerations. The relative benefits received by
         the Company on the one hand and the Underwriters on the other shall be
         deemed to be in the same proportions as the total proceeds from the
         offering (net of underwriting discounts and commission but before
         deducting expenses) received by the Company bear to the total
         underwriting discounts and commissions received by the Underwriters, in
         each case as set forth in the table on the cover page of the
         Prospectus. The relative fault of the Company on the one hand and the
         Underwriters on the other shall be determined by reference to, among
         other things, whether the untrue or alleged untrue statement of a
         material fact or the omission or alleged omission to state a material
         fact relates to information supplied by the Company or by the Under
         writers, and the parties' relative intent, knowledge, access to
         information and opportunity to correct or prevent such statement or
         omission. The amount paid or payable by a party as a result of the
         losses, claims, damages and liabilities referred to above shall be
         deemed to include any legal or other fees or expenses incurred by such
         party in its reasonable judgment in connection with investigating or
         defending any claim or action.

                  The Company and the Underwriters agree that it would not be
         just and equitable if contribution pursuant to this subsection (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. Notwithstanding the provisions
         of this subsection (d), no Under writer shall be required to contribute
         any amount in excess of the underwriting discount applicable to the
         Debentures underwritten by such Underwriter and distributed to the
         public. No person guilty of fraudulent
<PAGE>   21
         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 sixth paragraph under the caption "Underwriting" on page
         [S-42] of the Prospectus Supplement concerning stabilization by the
         Underwriters and the third paragraph under the caption "Underwriting"
         on page [S-42] of the Prospectus Supplement concerning the terms of the
         offering by the Underwriters constitute the only information furnished
         to the Company in writing by the Underwriters expressly for use in the
         Registration Statement, the Prospectus or the Preliminary Prospectus
         (as the same may have been amended or supplemented prior to the date
         of the Prospectus).

                  (e) The indemnity and contribution agreements contained in
         this Section 9 and the covenants, warranties and representations of the
         Company contained in this Agreement shall remain in full force and
         effect, regardless of any investigation made by or on behalf of the
         Underwriter indemnified party or by or on behalf of any Company
         indemnified party, and shall survive any termination of this Agreement
         or the issuance and delivery of the Debentures. The Company and the
         Underwriters agree promptly to notify the other of the commencement of
         any litigation or proceeding against it and, in the case of the
         Company, against any of the Company's officers and directors, in
         connection with the issuance and sale of the Debentures or in
         connection with the Registration Statement, the Prospectus or the
         Preliminary Prospectus (as the same may have been amended or
         supplemented prior to the date of the Prospectus).

         10.      Other Agreements: Each of the Company and the Underwriters
represents and agrees that (a) it has not offered or sold, and for a period of
six months after the date of issue of the Debentures will not offer or sell, any
Debentures to persons in the United Kingdom except to persons whose ordinary
activities involve them in acquiring, holding, managing or disposing of
investments (as principal or agent) for the purposes of their businesses or
otherwise in circumstances which do not constitute an offer to the public in the
United Kingdom for the purposes of the Public Offers of Securities Regulations
1995, (b) it has complied and will comply with all applicable provisions of the
Public Offers of Securities Regulations 1995 and the Financial Services Act 1986
with respect to anything done by it in relation to the Debentures in, from or
otherwise involving the United Kingdom and (c) it has only issued or passed on
and will only issue or pass on in the United Kingdom any document received by it
in connection with the issue or sale of Debentures to a person who is of a kind
described in Article 11(3) of the Financial Services Act of 1986 (Investment
Advertisements) (Exemptions) Order 1996 (as amended) or is a person to whom the
document may otherwise lawfully be issued or passed on.

          Re:     Del Webb Corporation
                  Public Offering of $200 Million of
                  [  ]% Senior Subordinated Debentures due 2010

Ladies and Gentlemen:

                   We have acted as special counsel to Del Webb Corporation, a
Delaware corporation (the "Company"), in connection with its sale to you of $200
million of [ ]% Senior Subordinated Debentures Due 2010 (the "Debentures")
pursuant to the Underwriting Agreement, dated February [ ], 1999, between each
of you and the Company (the "Underwriting Agreement"). This opinion is rendered
to you pursuant to Section 6(a) of the Underwriting Agreement.

                  In connection with our examination of documents as described
below, we have assumed the genuineness of all signatures on, and the
authenticity of, all documents submitted to us as originals and the conformity
to original documents of all documents submitted to us as copies. With respect
to agreements and instruments executed by natural persons, we have assumed the
legal competency of such persons.

                 For the purpose of rendering this opinion, we have made such
factual and legal inquiries as we deemed necessary under the circumstances and
in that connection we have examined, among other things, originals or copies of
the following:

                  (1)      The registration statement on Form S-3 (file number
                           333-63671) filed by the Company with the Securities
                           and

                           Exchange Commission (the "Commission") on September
                           18, 1998 for the purpose of registering the sale of
                           various securities, including Senior Subordinated
                           Debt Securities, under the Securities Act of 1933, as
                           amended (the "Securities Act"), the related Form T-1
                           filed with the Commission for the purpose of
                           qualifying the Indenture (defined below) under the
                           Trust Indenture Act of 1939, as amended (the "Trust
                           Indenture Act") and the prospectus included as part
                           of the Registration Statement (defined below). The
                           registration statement in the form in which it became
                           effective on October 22, 1998, including the
                           documents incorporated by reference therein to the
                           extent not modified or superseded thereby, is
                           referred to below as the "Registration Statement",
                           the prospectus of the Company dated October 22, 1998,

                           therein to the extent not modified or superseded
                           thereby, is referred to below as the "Prospectus" and
                           the Prospectus, as supplemented by the Prospectus

                           they constitute statements of United States federal
                           tax laws, are correct in all material respects.

                 (xvii)    Neither the Company nor any of its subsidiaries is an
                           "investment company" within the meaning of the
                           Investment Company Act of 1940, as amended, or is
                           subject to regulation thereunder.

                 During the course of the preparation of the
Prospectus/Prospectus Supplement, we participated in conferences with
representatives of the Company, its independent accountants, you and your
counsel, at which conferences the contents of the Registration Statement,
Prospectus and Prospectus/Prospectus Supplement and related matters were
discussed. We have not independently verified the accuracy, completeness or
fairness of the statements contained in the Registration Statement, Prospectus
or Prospectus/Prospectus Supplement and the nature of our participation is such
that we are unable to assume, and do not assume, any responsibility for the
accuracy, completeness or fairness of such statements. However, based upon our
participation as described in this paragraph, we have no reason to believe and
do not believe that the Registration Statement, Prospectus or the
Prospectus/Prospectus Supplement or any documents incorporated by reference
therein (provided that we express no opinion and make no other statement as to
the financial statements, financial statement notes and financial statement
schedules and other financial and statistical data contained therein or with
respect to the T-1), as of their respective effective or issue dates and as of
the date hereof, contained or contains any untrue statement of a material fact
or omitted or omits to state a material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading.

                 Our opinion set forth in paragraphs (viii) and (ix) above is
subject to (a) the effect of applicable bankruptcy, reorganization, insolvency,
moratorium and other similar laws and court decisions of general application,
including without limitation, statutory or other laws regarding fraudulent or
preferential transfers relating to, limiting or affecting the enforcement of
creditors' rights generally and (b) general principles of equity which may limit
the enforceability of any of the remedies, covenants or other provisions of the
Debentures and the Indenture, as well as the availability of injunctive relief
or other equitable remedies, and the application of principles of equity
(regardless of whether enforcement is considered in

proceedings at law or in equity) as such principles relate to, limit or affect
the enforcement of creditors' rights generally. In addition, we express no
opinion as to: (a) any provisions of the Debentures or the Indenture regarding
the remedies available to any person (1) to take discretionary action that is
arbitrary, unreasonable or capricious or is not taken in good faith or in a
commercially reasonable manner, whether or not such action is permitted under
the Debentures or the Indenture, or (2) for violations or breaches that are
determined by a court to be non-material; (b) with respect to subparagraphs
(x)(B), (C), (D), (E) and (F), whether compliance by the Company with Sections
4.14 or 4.15 of the Indenture, by making a "Change of Control Offer" or a "Net
Worth Offer" (as defined therein), the creation of a lien on property of the
Company under the fourth paragraph of Section 7.07 of the Indenture or the
existence of a "Default" or "Event of Default" under Article 6 of the Indenture
will constitute a default, event of default or cross-default under any of the
indentures, mortgages, deeds of trust, bank loans or credit agreements or other
similar written agreements or instruments referred to in subparagraphs (x)(B),
(C), (D), (E) and (F); (c) with respect to whether acceleration of the
Debentures may affect the collectibility of that portion of the stated principal
amount thereof that might be determined to constitute unearned interest thereon;
(d) the enforceability of the waivers of rights or defenses provided for in
Section 4.12 of the Indenture; or (e) the enforceability under certain
circumstances under law or court decisions of provisions providing for the
indemnification of or contribution to a party with respect to a liability where
such indemnification or contribution is contrary to public policy. Our opinion
in paragraphs (viii) and (ix) is subject to the assumption that the Indenture
has been duly authorized, executed and delivered by the Trustee and the Agent
and constitutes a valid and binding agreement of the Trustee and the Agent,
enforceable against the Trustee and the Agent in accordance with its terms,
subject to exceptions of the type contained above in this paragraph.

                  This letter is limited to the facts and the law as they exist
on the date hereof. In addition, with respect to statements in this letter based
on our knowledge, (i) we have advised you only as to knowledge obtained by us in
connection with matters to which we have given substantive attention as counsel
to the Company in the form of legal consultation and (ii) such knowledge refers
only to the knowledge of the lawyers in our firm participating in the
preparation of the Registration Statement and the Prospectus/Prospectus
Supplement (being Steven Meiers, Stephen Tolles, Larry Furst and ______________)
and not to the knowledge of every lawyer in our firm. The individuals mentioned
above are those whom, we believe, are the

appropriate persons of whom to inquire in rendering the opinions given as to our
knowledge herein. Please be advised that (a) our firm has not represented the
Company or any of its subsidiaries in any real property-related matters or given
substantive attention as counsel for the Company in the form of legal
consultation as to any license, decree, judgment or order as may exist with
respect to the business of Company and its subsidiaries (other than judgments or
orders favorable to the Company that are either not relevant to, or are
consistent with, the opinions expressed in this letter), (b) we are not
representing the Company in connection with any actual or threatened actions,
suits or proceedings and (c) except for a review of one of the certificates
referred to in paragraph (16), with your permission, we have not made any other
inquiries with respect thereto.

                  The Company is a Delaware corporation and, until it
reincorporated in Delaware in 1994, was an Arizona corporation. The Material
Subsidiaries are Arizona corporations, an Arizona limited liability company, an
Arizona limited partnership and a Delaware limited partnership. We are not
admitted to practice in Arizona or Delaware. However, we are generally familiar
with Title 10 of the Arizona Revised Statutes, Chapters 1-23 (Corporations and
Associations) and its predecessor statutes, the Delaware General Corporation Law
and the Delaware Revised Uniform Limited Partnership Act and, except as set
forth in the following sentence, have made such review thereof as we consider
necessary for the purpose of rendering the opinion contained in paragraphs (i),
(ii) (as to DEVCO), (iv), (v), (vii), (viii), (ix), (x)(A) and (xi) of this
opinion. Insofar as this opinion covers Arizona law (except with respect to
paragraph (iii) hereof), or Arizona, California, Delaware, Nevada, South
Carolina, Texas, Illinois or Florida state or local licenses, decrees, judgments
or orders and as to paragraphs (v), (xiii) (b) and (xiv), we have relied, with
your permission, on the opinion of Robertson C. Jones, Esq., Vice President and
General Counsel of the Company, to you, a copy of which is attached hereto, and
(a) as to paragraphs (ii) (second sentence) (with respect to the Material
Subsidiaries other than DEVCO), (x)(G) (except as to federal law), (xi) (except
as to federal law and the Delaware General Corporation Law), and (xiii) such
reliance is, with your permission, exclusive and without any independent
verification and (b) our opinion is subject to the same qualifications,
assumptions and limitations as are set forth in that opinion. We believe you and
we are justified in relying on that opinion. Subject to the foregoing, this
opinion is limited to federal, Arizona, Delaware and New York law, to the extent
set forth above. With respect to the opinion in paragraphs (i) and (ii) as to
valid existence and good standing and with respect to the opinion in

paragraph (iii), we have relied exclusively on certificates from the relevant
state authorities, except with respect to the qualification of DEVCO in Arizona,
in which case we have relied exclusively on oral advice from a representative of
the relevant state authority.

                 This letter is furnished to you in connection with the
Underwriting Agreement and the transactions contemplated thereby, is solely for
your benefit, may not be quoted in part by you or in whole or in part by any
other person and may not be relied upon by any other person or by you in any

                 [  ]% Senior Subordinated Debentures due 2010

Ladies and Gentlemen:

                  I am the General Counsel of Del Webb Corporation, a Delaware
corporation (the "Company"), and render this opinion to you pursuant to Section

you and the Company (the "Underwriting Agreement") in connection with the sale
by the Company to you of $200 million of [ ]% Senior Subordinated Debentures due
2010 (the "Debentures").

                  In connection with my examination of documents as described
below, I have assumed the genuineness of all signatures on, and the authenticity
of, all documents submitted to me as originals and the conformity to original
documents of all documents submitted to me as copies. With respect to agreements
and instruments executed by natural persons, I have assumed the legal competency
of such persons.

                 For the purpose of rendering this opinion, I have made such
factual and legal inquiries as I deemed necessary under the circumstances and in
that connection I have examined, among other things, originals or copies of the
following:

                           "Commission") on September 18, 1998 for the purpose
                           of registering the sale of various securities,
                           including Senior Subordinated Debt Securities, under

                           which have been delivered to you.

                 Based on the foregoing and in reliance thereon, and subject to

opinion that:

                 (i)       Each of the Material Subsidiaries (except DW Texas
                           L.P.) is a corporation organized, validly existing
                           and in good standing under the laws of Arizona, and
                           DW Texas L.P. is a limited partnership organized and
                           validly existing under the laws of Arizona. Each
                           Material Subsidiary has the corporate or partner ship
                           (as to DW Texas L.P.) power to own its properties and
                           conduct its business, in each case as described in
                           the Prospectus/Prospectus Supplement;

                 (ii)      The 2,500,000 shares and 375,000 shares of the

                           common stock issued on June 25 and July 25, 1991,
                           respectively, in a registered public offering, the
                           approximately 1.1 million shares of the Company's
                           common stock publicly issued in August and September
                           1987 in an exchange offer for then outstanding notes,
                           the 333,333 shares of common stock of the Company
                           issued on September 25, 1983, upon exercise of
                           warrants, in a registered public offering and the
                           approximately 3.2 million shares of common stock of
                           the Company issued in connection with the
                           underwritten call in May and June 1992 of the Com-
                           pany's 10-3/8% Convertible Subordinated Debentures
                           (none of which, I am informed, are now outstanding)
                           were all duly and validly authorized, fully paid,
                           non-assessable and not issued in violation of any
                           preemptive rights provided by Arizona law or the
                           Articles of Incorporation or Bylaws of the Company as
                           then in effect (the Company was incorporated in
                           Arizona at the time of each of these issuances of
                           common stock);

                 (iii)     To my knowledge and except for a 1989 lawsuit
                           challenging the issuance of the Company's 10-3/8%
                           Convertible Subordinated Debentures and the shares
                           issuable upon conversion thereof, which lawsuit was
                           dismissed without any payment by the Company to the
                           plaintiffs or their counsel, no shares of common
                           stock of the Company issued and outstanding as of the
                           date hereof have been or are the subject of any claim
                           or threatened claim that they were not duly
                           authorized, validly issued and non-assessable. Though
                           it is unclear precisely which statute of limitations
                           in Arizona law would govern any such claim, for
                           issuances when the Company was an Arizona
                           corporation, the limitation period by which any such
                           claim must be made is the later of six years from the
                           date of any issuance of shares or three years from
                           the date any claimant knew or should have known that
                           the applicable shares were not authorized, validly
                           issued and non-assessable;

                 (iv)      The Underwriting Agreement and the Indenture have

time may not exceed that amount except as provided in Section 2.07.

         The Securities shall be issuable only in registered form without
coupons and only in denominations of $1,000 or any integral multiple thereof.

         The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Securities. An authenticating agent may authenticate
Securities whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same right as an Agent to deal with the Company or
an Affiliate.

                  Every Global Security authenticated and delivered hereunder
shall bear a legend in substantially the following form:

                  THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE
INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITORY
OR A NOMINEE OF A DEPOSITORY. THIS GLOBAL SECURITY IS EXCHANGEABLE FOR
SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITORY 


                                       18
<PAGE>   29
OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE, AND
NO TRANSFER OF THIS SECURITY (OTHER THAN A TRANSFER OF THIS SECURITY AS A WHOLE
BY THE DEPOSITORY TO A NOMINEE OF THE DEPOSITORY OR BY A NOMINEE OF THE
DEPOSITORY TO THE DEPOSITORY OR ANOTHER NOMINEE OF THE DEPOSITORY) MAY BE
REGISTERED EXCEPT IN SUCH LIMITED CIRCUMSTANCES. EVERY SECURITY DELIVERED UPON
REGISTRATION OF TRANSFER OF, OR IN EXCHANGE FOR, OR IN LIEU OF, THIS GLOBAL
SECURITY SHALL BE A GLOBAL SECURITY SUBJECT TO THE FOREGOING, EXCEPT IN LIMITED
CIRCUMSTANCES. UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED
REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"),
TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT,
AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH
OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY
PAYMENT IS TO BE MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY
AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF
FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE
REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

         Owners of beneficial interests in a Global Security, as such, are not
Holders under the Indenture and will not be entitled to the rights of Holders
under the Indenture.

SECTION 2.03      REGISTRAR AND PAYING AGENT.

         The Company shall maintain or cause to be maintained in the Borough of
Manhattan, City of New York (the "New York Office"), State of New York, and in
such other locations as it shall determine, an office or agency: (i) where
securities may be presented for registration of transfer or for exchange
("Registrar"); (ii) where Securities may be presented for payment ("Paying
Agent"); and (iii) where notices and demand to or upon the Company in respect of
Securities and this Indenture may be served by the Holders. The Registrar shall
keep a register of the Securities and of their transfer and exchange. The
Company may appoint one or more co-registrars and one or more additional Paying
Agents. The term "Paying Agent" includes any additional Paying Agent. The
Company may change any Paying Agent, Registrar or co-registrar without prior
notice. The Company shall notify the Trustee of the name and address of any
Agent not a party to this Indenture and shall enter into an appropriate


                                       19
<PAGE>   30
agency agreement with any Registrar, Paying Agent or co-registrar not a party to
this Indenture. The agreement shall implement the provisions of this Indenture
that relate to such Agent. The Company or any of its subsidiaries may act as
Paying Agent, Registrar or co-registrar, except that for purposes of Articles 3
and 8 and Sections 4.14 and 4.15, neither the Company nor any of its
subsidiaries shall act as Paying Agent. If the Company fails to appoint or
maintain another entity as Registrar or Paying Agent, the Trustee shall act as
such, the Trustee shall initially act as Registrar and Paying Agent and the New
York Office shall initially be the office of the Trustee in the Borough of
Manhattan, City of New York, State of New York. The Company initially appoints
DTC to act as Depository with respect to the Securities. The Trustee shall act
as custodian for the Depository with respect to the Global Securities.

SECTION 2.04      PAYING AGENT TO HOLD MONEY IN TRUST.

         The Company shall require each Paying Agent (other than the Trustee,
who hereby so agrees), to agree in writing that the Paying Agent will hold in
trust for the benefit of Securityholders or the Trustee all money held by the
Paying Agent for the payment of principal or interest on the Securities, and
will notify the Trustee of any default by the Company in making any such
payment. While any such default continues, the Trustee may require a Paying
Agent to pay all money held by it to the Trustee. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee. Upon payment
over to the Trustee, the Paying Agent (if other than the Company or a
subsidiary) shall have no further liability for the money. If the Company or a
subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust
fund for the benefit of the Securityholders all money held by it as Paying
Agent.

SECTION 2.05      SECURITYHOLDER LISTS.

         The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Securityholders. If the Trustee is not the Registrar, the Company shall furnish
to the Trustee on or before each interest payment date and at such other times
as the Trustee may request in writing a list in such form and as of such date as
the Trustee may reasonably require of the names and addresses of
Securityholders.

SECTION 2.06      TRANSFER AND EXCHANGE.

         Where Securities are presented to the Registrar or a co-registrar with
a request to register a transfer or to exchange them for an equal principal
amount of Securities of other denominations, the Registrar shall register the
transfer or make the exchange if its requirements for such transactions are met.
To permit registrations of transfers and exchanges, the Company shall issue and
the Trustee shall authenticate Securities at the Registrar's request. No service
charge shall be made for any registration of transfer or exchange (except as
otherwise expressly permitted herein), but the Company may require payment of a
sum sufficient to cover any transfer tax or similar governmental charge payable
in connection therewith (other than any such transfer tax or similar
governmental charge payable upon exchanges pursuant to Sections 2.10, 3.06 or
9.05).

         The Company shall not be required (i) to issue, register the transfer
of or exchange Securities during a period beginning at the opening of business
15 days before the day of any selection of Securities for redemption under
Section 3.02 and ending at the close of business on the day of selection, or
(ii) to register the transfer or exchange of any Security so selected for
redemption in whole or in part, except the unredeemed portion of any Security
being redeemed in part.

         The Company will execute and the Trustee will, in accordance with this
Section 2.06 for so long as the Securities are to be issued in whole or in part
in the form of one or more Global Securities, authenticate and deliver one or
more Global Securities that will (i) represent and will be denominated in an
amount equal to the aggregate outstanding principal amount of the Securities to
be represented by such Global Security or Securities, (ii) be registered in the
name of the Depository for such Global Security or Securities or the nominee of
such Depository, (iii) be delivered by the Trustee to such Depository or
pursuant to such Depository's instructions and (iv) bear the legends set forth
in Section 2.02 hereof.

         Each Depository appointed in accordance herewith for a Global Security
must, at the time of its appointment and at all times while it serves as
Depository, be a clearing agency registered under the Exchange Act and any other
applicable statute or regulation.

         Notwithstanding any other provision of this Section 2.06, unless and
until it is exchanged in whole for Securities in definitive form, a Global
Security representing all or a portion of the Securities may not be transferred
except as a whole by the Depository to a nominee of such Depository or by a
nominee of such Depository to such


                                       21
<PAGE>   32
Depository or another nominee of such Depository or by such Depository or any
such nominee to a successor Depository or a nominee of such successor
Depository.

         If (i) the Company notifies the Trustee in writing that at any time the
Depository is unwilling or unable to continue as Depository or if at any time
the Depository will no longer be eligible to act as such under this Section
2.06, and a successor Depository is not appointed by the Company within 90 days
after the Company receives notice from the Depository or otherwise becomes aware
of such unwilling ness, inability or ineligibility, (ii) the Company at any time
and in its sole discretion determines that the Securities issued in the form of
one or more Global Securities will no longer be represented by such Global
Security or Securities, or (iii) an Event of Default has occurred and is
continuing, the Company will execute and deliver to the Trustee as promptly as
practicable Securities in definitive form, together with an Officers'
Certificate relating to the authentication and delivery of such Securities, and
the Trustee, as promptly as practicable after the receipt of such Securities and
Officers' Certificate, will authenticate and deliver Securities in definitive
form in an aggregate principal amount equal to the principal amount of, and
containing terms and provisions identical to, the Global Security or Securities
in exchange for such Global Security or Securities.

         Upon the exchange of a Global Security in whole or in part for
Securities in definitive form, such Global Security shall be cancelled by the
Trustee. Securities in definitive form issued in exchange for a Global Security
pursuant to this Section 2.06 will be registered in such names and in such
authorized denominations as the Depository, pursuant to instructions from its
direct or indirect participants or otherwise, will instruct the Trustee in
writing. The Trustee will deliver such Securities in definitive form to the
Persons in whose names such Securities are so registered or as it may otherwise
be directed by the Depository. Upon the exchange of less than the entire
principal amount of a Global Security for Securities in definitive form, the
Company will also execute, and the Trustee, upon receipt of an Officers'
Certificate will also authenticate and deliver, a new Global Security in
aggregate principal amount equal to the difference between the principal amount
of the surrendered Global Security and the aggregate principal amount of
Securities in definitive form issuable upon such exchange.

         In any exchange provided for in any of the preceding paragraphs in this
Section, the Company will execute and the Trustee will authenticate and deliver
Securities in definitive form in authorized denominations.


                                       22
<PAGE>   33
         If a Security in definitive form is issued in exchange for any portion
of a Global Security after the close of business at the office or agency where
such exchange occurs on or after any regular record date for an interest
payment date and before the opening of business at such office or agency on the
next interest payment date, interest will not be payable on such interest
payment date or proposed date for payment, as the case may be, in respect of
such Security in definitive form, but will be payable on such interest payment
date only to the Person to whom interest in respect of such portion of such
Global Security is payable in accordance with the provisions of this Indenture.

         None of the Company, the Trustee, any agent of the Trustee, any Paying
Agent or the Registrar will have any responsibility or liability for any aspect
of the Depository's records relating to or payments made on account of
beneficial ownership interests in a Global Security or for maintaining,
supervising or reviewing any of the Depository's records relating to such
beneficial ownership interests.


SECTION 2.07      REPLACEMENT SECURITIES.

         If the Holder of a Security claims that the Security has been lost,
destroyed or wrongfully taken, the Company shall issue and the Trustee shall
authenticate a replacement Security if the Trustee's and the Company's
requirements are met. If required by the Trustee or the Company as a condition
of receiving a replacement Security, the Holder must provide an indemnity bond
sufficient, in the judgment of both the Company and the Trustee, to fully
protect the Company, the Trustee, any Agent and any authenticating agent from
any loss which any of them may suffer if the Security is replaced. The Company
may charge for its expenses in replacing any Security.

         Every replacement Security is an additional obligation of the Company.

SECTION 2.08      OUTSTANDING SECURITIES.

         The Securities outstanding at any time are all the Securities properly
authenticated by the Trustee except for those cancelled by the Trustee, those
delivered to it for cancellation, and those described in this Section as not
outstanding.

         If a Security is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Security is held by a bona fide purchaser.


                                       23
<PAGE>   34
         If Securities are considered paid under Section 4.01, they cease to be
outstanding and interest on them ceases to accrue.

         A Security does not cease to be outstanding because the Company or an
Affiliate of the Company holds the Security.

SECTION 2.09      WHEN TREASURY SECURITIES DISREGARDED.

         In determining whether the Holders of the required principal amount of
Securities have concurred in any direction, waiver or consent, Securities owned
by the Company or an Affiliate of the Company shall be considered as though they
are not outstanding, except that for the purposes of determining whether the
Trustee shall be protected in relying on any such direction, waiver or consent,
only Securities which the Trustee knows are so owned shall be so disregarded.

SECTION 2.10      TEMPORARY SECURITIES.

         Until definitive Securities are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Securities. Temporary
Securities shall be substantially in the form of definitive Securities but may
have variations that the Company considers appropriate for temporary Securities.
If temporary Securities (other than a Global Security) are issued, the Company
will cause definitive Securities to be prepared without unreasonable delay.
After the preparation of definitive Securities, the temporary Securities shall
be exchangeable for definitive Securities upon surrender of the temporary
Securities at any office or agency of the Company designated pursuant to Section
2.03 without charge to the Holder. Upon surrender for cancellation of any one or
more temporary Securities the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of authorized denominations. Until so exchanged, the
temporary Securities shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities.

SECTION 2.11      CANCELLATION.

         The Company at any time may deliver Securities to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Securities surrendered to them for registration of transfer, exchange or
payment. The Trustee and no one else shall cancel all Securities surrendered for
registration of transfer, exchange, payment, replacement or cancellation and
shall dispose of cancelled Securities as the Company directs; provided, however,
that the Trustee shall not be


                                       24
<PAGE>   35
required to destroy such cancelled Securities. The Company may not issue new
Securities to replace Securities that it has paid or that have been delivered to
the Trustee for cancellation.

SECTION 2.12      DEFAULTED INTEREST.

         If the Company fails to make a payment of interest on the Securities,
it shall pay such defaulted interest plus any interest payable on the defaulted
interest in any lawful manner. It may pay such defaulted interest, plus any such
interest payable on it, to the persons who are Securityholders on a subsequent
special record date. The Company shall fix any such record date and payment
date. At least 15 days before any such record date, the Company shall mail to
Securityholders a notice that states the record date, payment date and amount of
such interest to be paid.

SECTION 2.13      CUSIP NUMBER.

         The Company in issuing the Securities may use a "CUSIP" number, and if
so, such CUSIP number shall be included in notices of redemption or exchange as
a convenience to Holders; provided, however, that any such notice may state that
no representation is made as to the correctness or accuracy of the CUSIP number
printed in the notice or on the Securities and that reliance may be placed only
on the other identification numbers printed on the Securities. The Company will
promptly notify the Trustee of any change in the CUSIP number.

                                   REDEMPTION

SECTION 3.01      NOTICES TO TRUSTEE.

         If the Company elects to redeem Securities pursuant to the optional
redemption provisions of paragraph 5 of the Securities, it shall notify the
Trustee of the redemption date and the principal amount of Securities to be
redeemed. The redemption price shall be the amount determined pursuant to
paragraph 5 of the Securities.

         The Company shall give each notice provided for in this Section at
least 50 days before the redemption date (unless a shorter notice period shall
be satisfactory to the Trustee).


                                       25
<PAGE>   36
SECTION 3.02      SELECTION OF SECURITIES TO BE REDEEMED.

         If less than all the Securities are to be redeemed, the Trustee shall
select the Securities to be redeemed pro rata, by lot or by another means that
is in compliance with the requirements of the principal securities exchange, if
any, on which the Securities are listed. The Trustee shall make the selection
not more than 75 days and not less than 50 days before the redemption date from
Securities outstanding not previously called for redemption. The Trustee may
select for redemption portions of the principal of Securities that have
denominations larger than $1,000. Securities and portions of them it selects
shall be in amounts of $1,000 or integral multiples of $1,000. Provisions of
this Indenture that apply to Securities called for redemption also apply to
portions of Securities called for redemption. The Trustee shall notify the
Company promptly of the Securities or portions of Securities to be called for
redemption.

SECTION 3.03      NOTICE OF REDEMPTION.

         At least 30 days but not more than 60 days before a redemption date,
the Company shall mail a notice of redemption to each Holder whose Securities
are to be redeemed.

         The notice shall identify the Securities to be redeemed and shall
state:

                  (1) the redemption date;

                  (2) the redemption price;

                  (3) if any Security is being redeemed in part, the portion of
         the principal amount of such Security to be redeemed and that, after
         the redemption date, upon surrender of such Security, a new Security
         or Securities in principal amount equal to the unredeemed portion will
         be issued;

                  (4) that Securities called for redemption must be surrendered
         to the Paying Agent to collect the redemption price;

                  (5) that interest on Securities called for redemption ceases
         to accrue on and after the redemption date (unless the Company defaults
         in the payment of the redemption price);


                                       26
<PAGE>   37
                  (6) the paragraph of the Securities pursuant to which the
         Securities are being redeemed;

                  (7) the aggregate principal amount of Securities that are
         being redeemed;

         (8) the CUSIP number of the Securities (provided that the disclaimer
permitted by Section 2.13 may be made); and

                  (9) the name and address of the Paying Agent.

         At the Company's request, the Trustee shall give notice of redemption
in the Company's name and at its expense.

SECTION 3.04      EFFECT OF NOTICE OF REDEMPTION.

         Once notice of redemption is mailed, Securities called for redemption
become due and payable on the redemption date at the price set forth in the
Security.

SECTION 3.05      DEPOSIT OF REDEMPTION PRICE.

         On or before the redemption date, the Company shall deposit with the
Trustee or with the Paying Agent money in immediately available funds sufficient
to pay the redemption price of and accrued interest on all Securities to be
redeemed on that date. The Trustee or the Paying Agent shall return to the
Company any money not required for that purpose.

SECTION 3.06      SECURITIES REDEEMED IN PART.

         Upon surrender of a Security that is redeemed in part, the Company
shall issue and the Trustee shall authenticate for the Holder at the expense of
the Company a new Security equal in principal amount to the unredeemed portion
of the Security surrendered.

                                    COVENANTS

SECTION 4.01      PAYMENT OF SECURITIES.

         The Company shall pay the principal of and interest on the Securities
on the dates and in the manner provided in the Securities. Principal and
interest shall be considered paid on the date due if the Trustee or Paying Agent
(other than the Company or a subsidiary) holds on that date money designated for
and sufficient to pay all principal and interest then due; provided, however,
that money held by the Paying Agent for the benefit of holders of Senior Debt
pursuant to the provisions of Article 11 hereof shall not be considered paid
within the meaning of this Section 4.01.

         To the extent lawful, the Company shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on (i)
overdue principal, at the rate borne by the Securities, compounded semiannually
and (ii) overdue installments of interest (without regard to any applicable
grace period) at the same rate, com pounded semiannually.

SECTION 4.02      SEC REPORTS.

         The Company shall deliver to the Trustee, within 15 days after it files
them with the SEC, copies of the annual reports and of the information,
documents and other reports (or copies of such portions of any of the foregoing
as the SEC may by rules and regulations prescribe) which the Company is required
to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. The
Company also shall comply with the other provisions of TIA Section 314(a). The
Company shall timely comply with its reporting and filing obligations under the
applicable federal securities law.

         If the Company is at any time not required to file annual or quarterly
reports pursuant to Section 13 or 15(d) of the Exchange Act, the Company will
file with the Trustee, within 15 days after the last date on which it would have
been required to make such a filing with the SEC, and will upon request of a
Holder mail to that Holder (as soon as practical after receipt of such request)
at his or her address as it appears on the register of Securities kept by the
Registrar, audited annual financial statements prepared in accordance with
generally accepted accounting principles and unaudited quarterly financial
statements. Such financial statements shall be accompanied by a Management's
Discussion and Analysis of Financial Condition and Results


                                       28
<PAGE>   39
of Operations of the Company for the period reported upon in substantially the
form required under the rules and regulations of the SEC, or any successor form
of similar disclosure then required under the rules and regulations of the SEC.

SECTION 4.03      COMPLIANCE CERTIFICATE.

         The Company shall deliver to the Trustee, within 60 days after the end
of the first three fiscal quarters and within 120 days after the end of each
fiscal year of the Company, an Officers' Certificate stating that a review of
the activities of the Company and its subsidiaries during the preceding fiscal
period has been made under the supervision of the signing Officers with a view
to determining whether the Company has fully performed its obligations under
this Indenture and further stating, as to each such Officer signing such
certificate, that to the best of his or her knowledge the Company has kept,
observed, performed and fulfilled each and every covenant contained in this
Indenture and is not in default in the performance or observance of any of the
terms and conditions hereof (or, if a Default or Event of Default shall have
occurred, describing all such Defaults or Events of Default of which he or she
may have knowledge) and that to the best of his or her knowledge no event has
occurred and remains in existence by reason of which payments on account of the
principal of or interest on the Securities are prohibited.

         The Company will, so long as any of the Securities are outstanding,
deliver to the Trustee, forthwith upon becoming aware of (i) any Default, Event
of Default or default in the performance of any term or condition in this
Indenture or (ii) any event of default under any other mortgage, indenture or
instrument as that term is used in Section 6.01(4), an Officers' Certificate
specifying such Default, Event of Default or default.

         So long as not contrary to the then current recommendations of the
American Institute of Certified Public Accountants, at the time the Officers'
Certificate described in the second preceding paragraph is filed with respect
to any fiscal year end of the Company, the Company also will file with the
Trustee a letter or statement of the independent accountants who shall have
certified the financial statements of the Company for its preceding fiscal year
in connection with the annual report of the Company to its stockholders for such
year to that effect that, in making the examination necessary for certification
of such financial statements, nothing came to their attention that would lead
them to believe that the Company has violated any of the terms or conditions
contained in this Indenture, which Default remains uncured at the date of such
letter or statement or, if they shall have obtained knowledge of any such
uncured Default, specifying in such letter or statement such Default or Defaults
and


                                       29
<PAGE>   40
the nature thereof, it being understood that such accountants shall not be
liable directly or indirectly for failure to obtain knowledge of any such
Default or Defaults and that their examination was not directed primarily toward
obtaining knowledge of such noncompliance.

SECTION 4.04      MAINTENANCE OF OFFICE OR AGENCY.

         The Company will maintain or cause to be maintained the office or
agency required under Section 2.03. The Company will give prompt written notice
to the Trustee of the location, and any change in the location, of such office
and agency not maintained by the Trustee.

         The Company may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for any
or all such purposes and may from time to time rescind such designation;
provided, however, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain or cause to be maintained an
office or agency in the City of New York for such purpose.

SECTION 4.05      RESTRICTIONS ON ADDITIONAL INDEBTEDNESS.

         After the date hereof, the Company will not, and will not permit any of
its Restricted Subsidiaries to, directly or indirectly, create, incur, assume,
guarantee, extend the maturity of or otherwise become liable with respect to
(collectively, "incur"), any Indebtedness (other than Indebtedness between the
Company and any of its Wholly Owned Restricted Subsidiaries or among its Wholly
Owned Restricted Subsidiaries) or issue any Disqualified Stock unless, after
giving effect thereto, the Company's Consolidated Fixed Charge Coverage Ratio on
the date thereof would be at least 3.0 to 1.0.

         Notwithstanding the foregoing, the Company or any Restricted Subsidiary
may incur the following Indebtedness (plus interest and premium, if any,
thereon) without regard to the foregoing limitation (although any Indebtedness
so incurred will be included in the determination of the Consolidated Fixed
Charge Coverage Ratio thereafter): (i) Indebtedness under credit agreements in
an aggregate principal amount at any one time outstanding of not more than $150
million; (ii) Indebtedness evidenced by the Securities; (iii) Indebtedness under
Guarantees of Indebtedness incurred in the ordinary course of business of
suppliers or customers, which Guarantees are also in the ordinary course of
business of the Company or its subsidiaries; (iv) Non-Recourse Indebtedness
incurred for the acquisition and/or improvement of real


                                       30
<PAGE>   41
property and secured by Liens on such real property and/or improvements; (v)
Refinancing Indebtedness; (vi) Excluded Debt; and (vii) Indebtedness not
otherwise permitted to be incurred pursuant to clauses (i) through (vi) above
which, together with any other then outstanding Indebtedness incurred pursuant
to this clause (vii) (and refinancings thereof), has an aggregate principal
amount at the time of incurrence of not in excess of 20 percent of Consolidated
Tangible Net Worth of the Company (as of the last fiscal quarter for which
financial results have then been reported).

         Nothing in this Section 4.05 will restrict any Unrestricted Subsidiary
from incurring Indebtedness, and Indebtedness of any Unrestricted Subsidiary
will not be included in the Consolidated Fixed Charge Coverage Ratio, as long as
the Unrestricted Subsidiary incurring such Indebtedness remains an Unrestricted
Subsidiary. As of the date hereof, all of the Company's operating subsidiaries
are Restricted Subsidiaries under this Indenture.

SECTION 4.06      RESTRICTIONS ON DIVIDENDS AND OTHER PAYMENTS.

         The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly make any Restricted Payment after the
date hereof, except as provided below in this Section 4.06, if at the time of
such Restricted Payment:

                  (i) a Default or Event of Default shall have occurred and be
         continuing or shall occur as a consequence thereof;

                  (ii) the amount of such Restricted Payment, when added to the
         aggregate amount of all Restricted Payments made after February 11,
         1994 other than pursuant to clause (a) below, exceeds the sum of: (1)
         50 percent of the Company's Consolidated Net Earnings (excluding
         Consolidated Net Earnings attributable to dividends or distributions
         from Unrestricted Subsidiaries) accrued during the period (taken as one
         accounting period) since December 31, 1993 (or, if such aggregate
         Consolidated Net Earnings shall be a deficit, minus 100% of such
         aggregate deficit), plus (2) the sum of (x) 100% of the book value of
         property and assets (other than cash), determined at the time such
         property or assets were contributed as an Investment to an Unrestricted
         Subsidiary, received by the Company or its Wholly Owned Restricted
         Subsidiaries from any of their Unrestricted Subsidiaries, up to the
         amount of the Company's and its Restricted Subsidiaries' aggregate net
         Investment in Unrestricted Subsidiaries, provided that such property so
         received is substantially


                                       31
<PAGE>   42
         similar to the property contributed to the Unrestricted Subsidiaries,
         (y) 100% of the cash distributions or cash dividends received by the
         Company or its Wholly Owned Restricted Subsidiaries from any
         Unrestricted Subsidiaries, to the extent the amount of such cash and
         such book value of property and assets referred to in clause (x) above
         do not exceed the amount of the Company's and its Restricted
         Subsidiaries' aggregate net Investment in Unrestricted Subsidiaries and
         (z) 50% of any other cash distributions or cash dividends received by
         the Company and its Wholly Owned Restricted Subsidiaries from
         Unrestricted Subsidiaries, plus (3) the aggregate net proceeds,
         including the fair market value of property other than cash (such fair
         market value to be determined by a majority of the disinterested
         members of the full Board of Directors of the Company, whose good faith
         determination shall be conclusive and evidenced by a resolution
         certified by an Officers' Certificate and filed with the Trustee),
         received by the Company from the issuance of Capital Stock of the
         Company (other than to a subsidiary of the Company) that is not
         Disqualified Stock since December 31, 1993, plus (4) 100% of the
         principal amount of any Indebtedness of the Company or a Wholly Owned
         Restricted Subsidiary that is converted into or exchanged for Capital
         Stock of the Company that is not Disqualified Stock since December 31,
         1993, plus (5) 100% of the Released Asset Value since February 11,
         1994, plus (6) 100% of the reductions since February 11, 1994 in
         Guarantees of the Company which are Investments in Unrestricted
         Subsidiaries to the extent such Guarantees were classified as
         Restricted Payments; or

                  (iii) the Company would be unable to incur an additional $1 of
         Indebtedness under the Consolidated Fixed Charge Coverage Ratio in
         Section 4.05.

Notwithstanding the foregoing, the provisions of this Section 4.06 will not
prevent:

                  (a) Restricted Payments since February 11, 1994 up to, but not
         exceeding, $50 million not otherwise permitted above, provided that any
         Restricted Payments made pursuant to this clause (a) shall be evidenced
         by filing with the Trustee of an Officers' Certificate certifying that
         such Restricted Payment has been made under this exception and,
         provided further, that no Restricted Payment (other than a Restricted
         Payment pursuant to clause (iii)(a) of the definition of Restricted
         Payment) shall be made pursuant to this clause (a) if at the time of
         such Restricted Payment a Default or Event of Default shall have
         occurred and be continuing or shall occur as a consequence thereof;


                                       32
<PAGE>   43
                  (b) the purchase since February 11, 1994 at a price of not
         more than $.05 per right of any rights issued or issuable pursuant to
         any future rights plan of the Company, provided that such purchases
         shall not exceed $1 million in the aggregate;

                  (c) the payment of any dividend within 60 days after the date
         of declaration thereof if the payment thereof would have complied with
         the limitations of this Indenture on the date of declaration; or

                  (d) the retirement of shares of the Company's Capital Stock in
         exchange for or out of the proceeds of a substantially concurrent sale
         (other than a sale to a subsidiary of the Company) of other shares of
         its Capital Stock (other than Disqualified Stock).

SECTION 4.07      LIMITATIONS ON RESTRICTIONS ON DISTRIBUTIONS
                  FROM RESTRICTED SUBSIDIARIES.

         The Company shall not, and will not permit any of its Restricted
Subsidiaries to, create or otherwise cause or suffer to exist or become
effective any consensual encumbrance or restriction (other than encumbrances or
restrictions imposed by law, by judicial or regulatory action or by provisions
in leases or 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 which is owned by the Company or any of its
other Restricted Subsidiaries, or pay interest on or principal of any
Indebtedness owed to the Company or any of its other Restricted Subsidiaries,
(ii) make loans or advances to the Company or any of its other Restricted
Subsidiaries or (iii) transfer any of its properties or assets to the Company or
any of its other Restricted Subsidiaries, except in each case for encumbrances
or restrictions existing under or by reason of (a) applicable statute, law,
rule, regulation or governmental order, (b) covenants or restrictions contained
in Indebtedness existing as of the date hereof, (c) any restrictions under any
note, indenture, agreement or other document evidencing any Acquired
Indebtedness that was permitted to be incurred pursuant to the provisions of
this Indenture, provided that such restrictions and encumbrances only apply to
assets that were subject to such restrictions and encumbrances prior to the
acquisition of such assets by the Company or its subsidiaries or assets acquired
with the proceeds of such assets, (d) restrictions or encumbrances replacing
those permitted by clause (b) or (c) which are not, in the judgment of the Board
of Directors, determined in good faith, more restrictive, (e) any restrictions
or encumbrances arising in connection with the replacement, renewal or extension
of any credit


                                       33
<PAGE>   44
agreement, credit facility or similar arrangement existing as of the date
hereof, provided that any such restrictions and encumbrances are not, in the
judgment of the Board of Directors, determined in good faith, more restrictive
than those in the credit agreement, credit facility or similar arrangement being
replaced, extended or renewed, as the case may be, (f) any restrictions or
encumbrances arising in connection with the refunding or refinancing of any
Indebtedness existing as of the date hereof, provided that any restrictions and
encumbrances of the type described in this clause that arise in connection with
such refunding or refinancing are not, in the judgment of the Board of
Directors, determined in good faith, more restrictive than those under the
agreement creating or evidencing the Indebtedness being refunded or refinanced,
(g) any agreement restricting the sale or other disposition of property securing
Indebtedness permitted by this Indenture if such agreement does not expressly
restrict the ability of a subsidiary of the Company to pay dividends or make
loans or advances and (h) reasonable and customary borrowing base covenants set
forth in credit agreements pursuant to which Indebtedness otherwise permitted by
this Indenture is outstanding (including but not limited to borrowing base
covenants substantially similar to those contained in the Revolving Loan
Agreement between Del Webb Communities, Inc. and First Interstate Bank of
Nevada, as agent for the lenders, as in effect on February 11, 1994), which
covenants restrict or limit the distribution of revenues or sale proceeds from
real estate or a real estate project based upon the amount of Indebted ness
outstanding on such real estate or real estate project and the value of some or
all of the remaining real estate or the project's remaining assets.

SECTION 4.08      LIMITATIONS ON TRANSACTIONS WITH AFFILIATES.

         The Company and each of its Restricted Subsidiaries will not, after the
date hereof, make any loan, advance, Guarantee or capital contribution to, or
for the benefit of, or sell, lease, transfer or otherwise dispose of any of its
properties 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, (i) any Affiliate of the Company or
any of its subsidiaries or (ii) any Person (or any Affiliate of such Person)
holding 10% or more of the Common Equity of the Company or any of its
subsidiaries (each an "Affiliate Transaction"), except on terms that are no less
favorable to the Company or the relevant Restricted Subsidiary, as the case may
be, than those that could have been obtained in a comparable transaction on an
arms length basis from a Person that is not an Affiliate.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, enter into an Affiliate Transaction involving or having a value
of more than $10 million unless (i) such Affiliate Transaction has been approved
by a majority of the


                                       34
<PAGE>   45
disinterested members of a Committee of the Board of Directors of the Company or
(ii) the Company has delivered an officer's certificate to the Trustee stating
that (a) the signatory officer was not a party to or otherwise interested in
such Affiliate Transaction and (b) the terms of such Affiliate Transaction are
not less favorable to the Company or the relevant Restricted Subsidiary, as the
case may be, than those that could have been obtained in a comparable
transaction on an arms length basis from a Person that is not an Affiliate.
Delivery of a certificate as required by this Indenture and described above
will, absent manifest fraud, constitute conclusive evidence that the terms of
the Affiliate Transaction in question are not less favorable to the Company or
the relevant Restricted Subsidiary, as the case may be, than those that could
have been obtained in a comparable transaction on an arms length basis from a
Person that is not an Affiliate.

         Notwithstanding the foregoing, the term "Affiliate Transaction" shall
not include any contract, agreement or understanding with or for the benefit of,
or plan for the benefit of, any or all employees of the Company or its
subsidiaries (in their capacity as such) that has been approved by the Company's
Board of Directors, a disinterested committee thereof or the Chief Executive
Officer of the Company (or his or her designee) or stock issuances to directors
pursuant to plans approved by shareholders.

SECTION 4.09      CONTINUED EXISTENCE.

         Subject to Article 5, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence.

SECTION 4.10      TAXES.

         The Company shall pay, prior to delinquency, all taxes, assessments and
governmental levies, except as contested in good faith and by appropriate
proceedings or where the failure to do so (together with all other such
failures) would not have a material adverse effect on the financial condition or
results of operations of the Company and its subsidiaries, taken as a whole.

SECTION 4.11      LIMITATION ON RANKING OF FUTURE INDEBTEDNESS.

         The Company shall not, directly or indirectly, incur, create, assume,
guarantee or otherwise become liable for any Indebtedness which is subordinated
in right of


                                       35
<PAGE>   46
payment to any Senior Debt of the Company and senior in right of payment to the
Securities.

SECTION 4.12      STAY, EXTENSION AND USURY LAWS.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, plead or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension or usury law wherever
enacted, now or at any time hereafter in force, that may affect the Company's
obligation to pay the Securities; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law insofar as such law applies to the Securities, and covenants that it will
not, by resort to any such law, hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law has been enacted.

SECTION 4.13      INVESTMENT COMPANY ACT.

         The Company shall not become an investment company subject to
registration under the Investment Company Act of 1940, as amended.

SECTION 4.14      CHANGE OF CONTROL.

         Following the occurrence of any Change of Control, the Company shall
offer (a "Change of Control Offer") to purchase all outstanding Securities at a
purchase price equal to 101% of the aggregate principal amount of the
Securities, plus accrued and unpaid interest to the date of purchase. The Change
of Control Offer shall be deemed to have commenced upon mailing of the notice
described in the next succeeding paragraph and shall terminate 20 business days
after its commencement, unless a longer offering period is required by law.
Promptly after the termination of the Change of Control Offer (the "Change of
Control Payment Date"), the Company shall purchase and mail or deliver payment
for all Securities tendered in response to the Change of Control Offer. If the
Change of Control Payment Date is on or after an interest payment record date
and on or before the related interest payment date, any accrued interest will be
paid to the person in whose name a Security is registered at the close of
business on such record date, and no additional interest will be payable to
Holders who tender Securities pursuant to the Change of Control Offer.

         Within 30 days after any Change of Control, the Company (with notice to
the Trustee), or the Trustee at the Company's request (and at the expense of the
Company),


                                       36
<PAGE>   47
will mail or cause to be mailed to all Holders on the date of the Change of
Control a notice of the occurrence of such Change of Control and of the Holders'
rights arising as a result thereof. Such notice will contain all instructions
and materials necessary to enable Holders to tender their Securities to the
Company. Such notice, which shall govern the terms of the Change of Control
Offer, shall state:

                  (1) that the Change of Control Offer is being made pursuant to
         this Section 4.14, the length of time the Change of Control Offer will
         remain open and that all Securities validly tendered will be accepted
         for payment;

                  (2) the purchase price and the Change of Control Payment Date;

                  (3) that any Security not tendered will continue to accrue
         interest;

                  (4) that any Security accepted for payment pursuant to the
         Change of Control Offer shall cease to accrue interest on the Change of
         Control Payment Date unless the Company defaults in the payment of the
         purchase price;

                  (5) that Holders electing to have a Security purchased
         pursuant to any Change of Control Offer will be required to surrender
         the Security, with the form entitled "Option of Holder to Elect
         Purchase" on the reverse of the Security completed, to the Company, a
         depositary, if appointed by the Company, or a Paying Agent at the
         address specified in the notice prior to termination of the Change of
         Control Offer;

                  (6) that Holders will be entitled to withdraw their election
         if the Company, depositary or Paying Agent, as the case may be,
         receives, not later than the expiration of the Change of Control Offer,
         or such longer period as may be required by law, a facsimile
         transmission or letter setting forth the name of the Holder, the
         principal amount of the Security the Holder delivered for purchase and
         a statement that such Holder is withdrawing his or her election to have
         the Security purchased; and

                  (7) that Holders whose Securities are purchased only in part
         will be issued Securities equal in principal amount to the unpurchased
         portion of the Securities surrendered.

         On or before a Change of Control Payment Date, the Company shall, to
the extent lawful, (i) if the Company appoints a depositary or Paying Agent,
deposit with


                                       37
<PAGE>   48
such depositary or Paying Agent money sufficient to pay the purchase price of
all Securities tendered, (ii) deliver or cause the depositary or Paying Agent to
deliver to the Trustee Securities so tendered and (iii) deliver an Officers'
Certificate identifying the Securities accepted for payment by the Company in
accordance with the terms of this Section 4.14. The depositary or the Paying
Agent, as the case may be, shall promptly mail or deliver to each tendering
Holder an amount equal to the purchase price of the Securities tendered by such
Holder and accepted by the Company for purchase. The Company will publicly
announce the results of the Change of Control Offer on the Change of Control
Payment Date. Any Change of Control Offer will be conducted in compliance with
applicable tender offer rules, including Section 14(e) of the Exchange Act and
Rule 14e-1 thereunder. For purposes of this Section 4.14, neither the Company
nor any of its subsidiaries shall act as Paying Agent or depositary.

SECTION 4.15      MAINTENANCE OF CONSOLIDATED TANGIBLE NET WORTH.

         (a) If the Company's Consolidated Tangible Net Worth at the end of each
of any two consecutive fiscal quarters (the last day of the second such fiscal
quarter being referred to as a "Deficiency Date") is less than $125 million (the
"Minimum Consolidated Tangible Net Worth"), then the Company shall, no later
than 60 days after a Deficiency Date (or 120 days if a Deficiency Date is also
the end of the Company's fiscal year), offer to purchase (a "Net Worth Offer")
10% of the principal amount of Securities originally issued hereunder (or such
lesser amount as may be outstanding at the time the Net Worth Offer is made)
(the "Offer Amount") at a purchase price equal to 100% of the aggregate
principal amount thereof, plus accrued and unpaid interest to the purchase date;
provided, however, that no such Net Worth Offer shall be required if, after the
Deficiency Date but prior to the timely delivery of the Officers' Certificate
required by this Section 4.15, capital is contributed or otherwise paid to the
Company or its subsidiaries sufficient to increase the Company's Consolidated
Tangible Net Worth to $125 million or more. The Net Worth Offer shall remain
open for a period of 20 business days following its commencement and no longer,
unless a longer period is required by law (the "Offer Period"). Promptly after
the termination of the Offer Period (the "Payment Date"), the Company shall
purchase and mail or deliver payment for the Offer Amount of Securities tendered
or, if less than the Offer Amount has been tendered, all Securities tendered in
response to the Net Worth Offer. If less than all of the Securities tendered in
response to the Net Worth Offer are to be purchased, the Company shall select
the Securities to be purchased on a pro rata basis. In no event shall the
Company's failure to meet the Minimum Consolidated Tangible Net Worth at the end
of any fiscal quarter be


                                       38
<PAGE>   49
counted towards the making of more than one Net Worth Offer. Any Net Worth Offer
shall be conducted in compliance with applicable regulations under the federal
securities law, including Exchange Act Rule 14e-1.

         (b) If the Payment Date is on or after an interest payment record date
and on or before the related interest payment date, any accrued interest will be
paid to the Person in whose name a Security is registered at the close of
business on such record date, and no additional interest will be payable to
Holders who tender Securities pursuant to the Net Worth Offer. The Company may
reduce the principal amount of Securities to be purchased pursuant to the Net
Worth Offer by subtracting 100% of the principal amount (excluding premium) of
Securities acquired by the Company subsequent to the Deficiency Date and
surrendered for cancellation through purchase (otherwise than pursuant to this
Section 4.15 or Section 4.14 hereof), redemption or exchange, and which were not
previously used as a credit against any obligation to repurchase Securities
pursuant to this Section.

         (c) The Company shall provide the Trustee with notice of the Net Worth
Offer at least 10 days before the notice of any Net Worth Offer is mailed to
Holders. Such notice shall state whether the Company elects to credit any
Securities against its obligations to repurchase Securities as provided above
and shall set forth the amount of such credit and the basis therefor (including
identification of any previously cancelled Securities not theretofore credited).
Such notice shall be accompanied by any Securities required to be delivered to
the Trustee for cancellation, as provided above, in order to be credited against
the Company's obligation to purchase Securities hereunder.

         (d) A Net Worth Offer shall be deemed to have commenced upon the
mailing by the Company (with notice to the Trustee) or by the Trustee at the
Company's request (and at the expense of the Company), by first class mail, of a
notice to each of the Holders. Such notice shall be mailed no later than 60 days
after the corresponding Deficiency Date (or 120 days if such Deficiency Date is
also the end of the Company's fiscal year). The notice shall, to the extent
permitted by applicable law, be accompanied by a copy of the information
regarding the Company which is (or would be, if the Company were subject to the
reporting requirements of the Exchange Act) required to be contained in a
Quarterly Report on Form 10-Q for the fiscal quarter ending on the Deficiency
Date if such fiscal quarter is one of the Company's first three fiscal quarters.
If such fiscal quarter is the Company's last fiscal quarter, a copy of the
information which is (or would be, if the Company were subject to the reporting
requirements of the Exchange Act) required to be contained in an Annual Report
on Form 10-K (including any financial statements or other information


                                       39
<PAGE>   50
required to be included or incorporated by reference therein) for the fiscal
year ending with such fiscal quarter shall either accompany the notice or be
delivered to Holders not less than 15 days before the Payment Date. The notice
shall contain all instructions and materials necessary to enable such Holders
to tender Securities pursuant to the Net Worth Offer. The notice, which shall
govern the terms of the Net Worth Offer, shall state:

                  (1) that the Net Worth Offer is being made pursuant to this
         Section 4.15 and the length of time the Net Worth Offer will remain
         open;

                  (2) the Offer Amount, the purchase price and the Payment Date;

                  (3) that any Security not tendered or accepted for payment
         will continue to accrue interest;

                  (4) that any Security accepted for payment pursuant to the Net
         Worth Offer shall cease to accrue interest on the Payment Date unless
         the Company defaults in payment of the purchase price;

                  (5) that Holders electing to have a Security purchased
         pursuant to any Net Worth Offer will be required to surrender the
         Security, with the form entitled "Option of Holder to Elect Purchase"
         on the reverse of the Security completed, to the Company, a depositary,
         if appointed by the Company, or a Paying Agent at the address specified
         in the notice prior to termination of the Net Worth Offer;

                  (6) that Holders will be entitled to withdraw their election
         if the Company, depositary or Paying Agent, as the case may be,
         receives, not later than the expiration of the Offer Period, or such
         longer period as may be required by law, a facsimile transmission or
         letter setting forth the name of the Holder, the principal amount of
         the Security the Holder delivered for purchase and a statement that
         such Holder is withdrawing his election to have the Security purchased;

                  (7) that, if the aggregate principal amount of Securities
         surrendered by Holders exceeds the Offer Amount, the Company shall
         select the Securities to be purchased on a pro rata basis (with such
         adjustments as may be deemed appropriate by the Company so that only
         Securities in denominations of $1,000, or integral multiples thereof,
         shall be purchased); and


                                       40
<PAGE>   51
                  (8) that Holders whose Securities are purchased only in part
         will be issued new Securities equal in principal amount to the
         unpurchased portion of the Securities surrendered.

         (e) On or before any Payment Date, the Company shall, to the extent
lawful, (i) accept for payment, on such a pro rata basis, Securities or portions
thereof validly tendered pursuant to the Net Worth Offer, (ii) if the Company
appoints a depositary or Paying Agent, deposit with such depositary or Paying
Agent money sufficient to pay the purchase price of all Securities or portions
thereof so accepted; (iii) deliver or cause such depositary or Paying Agent to
deliver to the Trustee Securities so accepted and (iv) deliver an Officers'
Certificate identifying the Securities or portions thereof accepted for payment
by the Company in accordance with the terms of this Section 4.15. The
depositary, the Paying Agent or the Company, as the case may be, shall promptly
mail or deliver to each tendering Holder an amount equal to the purchase price
of the Securities tendered by such Holder and accepted by the Company for
purchase, and the Trustee shall promptly authenticate and mail or deliver to
such Holders a new Security equal in principal amount to any unpurchased portion
of the Security surrendered. Any Securities not so accepted shall be promptly
mailed or delivered by the Company to the Holder thereof. The Company will
publicly announce the results of the Net Worth Offer on the Payment Date. For
purposes of this Section 4.15, neither the Company nor any of its subsidiaries
shall act as Paying Agent or depositary.

SECTION 5.01      WHEN THE COMPANY MAY MERGE, ETC.

         The Company shall not consolidate or merge with or into, or sell,
lease, convey or otherwise dispose of all or substantially all of its assets
(including by way of liquidation or dissolution) to any Person, unless:

                  (1) the Person formed by or surviving any such consolidation
         or merger (if other than the Company), or to which such sale, lease,
         conveyance or other disposition shall have been made (collectively, the
         "Successor"), is a corporation or other legal entity organized and
         existing under the laws of the United States, any state thereof or the
         District of Columbia;

                  (2) the Successor assumes by supplemental indenture in a form
         reasonably satisfactory to the Trustee all the obligations of the
         Company under the Securities and this Indenture;

                  (3) immediately after giving effect to such transaction no
         Default or Event of Default shall have occurred and be continuing;

                  (4) immediately after giving effect to such transaction and
         the use of any net proceeds therefrom, on a pro forma basis the
         Consolidated Tangible Net Worth of the Company or the Successor, as the
         case may be, would be at least equal to the Consolidated Tangible Net
         Worth of the Company immediately prior to such transaction; and

                  (5) the Consolidated Fixed Charge Coverage Ratio of the
         Company or the Successor, as the case may be, immediately after giving
         effect to such transaction, would be such that the Company or the
         Successor, as the case may be, would be entitled to incur at least $1
         of additional indebtedness under the Consolidated Fixed Charge Coverage
         Ratio test in Section 4.05.

         The Company shall deliver to the Trustee prior to the consummation of
the proposed transaction an Officers' Certificate to the foregoing effect and an
Opinion of Counsel stating that the proposed transaction and such supplemental
indenture comply with this Indenture.

         For purposes of this Section 5.01, a sale, lease, conveyance or other
disposition by the Company and/or its subsidiaries of all or substantially all
of the assets of the Company and its subsidiaries, taken as a whole, shall be
deemed a sale, lease, conveyance or other disposition of all or substantially
all of the assets of the Company.

SECTION 5.02      SUCCESSOR CORPORATION SUBSTITUTED.

         Upon any consolidation or merger, or any sale, lease, conveyance or
other disposition of all or substantially all of the assets of the Company in
accordance with Section 5.01, the Successor shall succeed to, and be substituted
for, and may exercise every right and power of, the Company under this Indenture
with the same effect as if the Successor had been named as the Company herein.

                              DEFAULTS AND REMEDIES

SECTION 6.01      EVENTS OF DEFAULT.

         An "Event of Default" with respect to any Securities occurs if:

                  (1) the Company defaults in the payment of interest on any
         Security when the same becomes due and payable (whether or not
         prohibited by Article 11 hereof) and the Default continues for a period
         of 30 days;

                  (2) the Company defaults in the payment of the principal of
         any Security when the same becomes due and payable whether at maturity,
         upon redemption at the option of the Company, by declaration of
         acceleration, or otherwise (whether or not prohibited by Article 11
         hereof);

                  (3) the Company fails to comply with any of its other
         agreements or covenants in, or provisions of, the Securities or this
         Indenture and such failure continues for the period and after the
         notice specified below;

                  (4) an event of default occurs under any mortgage, indenture
         or instrument under which there may be issued or by which there may be
         secured or evidenced any Indebtedness for money borrowed by the Company
         or any of its Restricted Subsidiaries (or the payment of which is
         Guaranteed by the Company or any of its Restricted Subsidiaries), other
         than Non-Recourse Indebtedness if (a) either (i) such event of default
         results from the failure to pay any such Indebtedness when due (whether
         at maturity or otherwise) or (ii) as a result of such event of default
         the maturity of such Indebtedness has been accelerated prior to its
         expressed maturity and (b) the principal amount of such Indebtedness,
         together with the principal amount of any other such Indebtedness in
         default for failure to pay principal when due or the maturity of which
         has been so accelerated, equals or exceeds $10 million or more in the


                                       43
<PAGE>   54
         aggregate, without such Indebtedness having been discharged or such
         acceleration rescinded within 30 days after notice to the Company from
         the Trustee or the Holders of 25% in principal amount of the Securities
         then outstanding; provided, however, that if such event of default
         shall be remedied, cured or waived, then the Event of Default
         hereunder, by reason of such event of default, shall be deemed likewise
         to have been remedied, cured or waived without further action by the
         Trustee or any of the Securityholders;

                  (5) a final judgment or final judgments, except to the extent
         the judgment or judgments are in respect of Non-Recourse Indebtedness,
         that exceed $10 million in the aggregate, for the payment of money, are
         entered by a court or courts of competent jurisdiction, and remain
         undischarged for a period (during which execution shall not be
         effectively stayed) of 60 days, against (i) the Company, (ii) any of
         its Material Subsidiaries which is at the time a Restricted Subsidiary
         or (iii) any subsidiary which is at the time a Restricted Subsidiary
         and which is (a) a member of a Material Subsidiary Group and (b)
         material to or holds material assets of (in each case as deter mined in
         good faith by the Board of Directors) the specific real estate project
         in respect of which it is a member of the Material Subsidiary Group;

                  (6) the Company, any Material Subsidiary which is at the time
         a Restricted Subsidiary or any subsidiary which is at the time a
         Restricted Subsidiary and which meets both of the tests for inclusion
         contained in subclauses (a) and (b) of Section 6.01(5)(iii), pursuant
         to or within the meaning of any Bankruptcy Law:

                           (A) commences a voluntary case,

                           (B) consents to the entry of an order for relief
                  against it in an involuntary case,

                           (C) consents to the appointment of a Custodian of it
                  or for all or substantially all of its property, or

                           (D) makes a general assignment for the benefit of its
                  creditors; or

                  (7) a court of competent jurisdiction enters a judgment, order
         or decree under any Bankruptcy Law that:


                                       44
<PAGE>   55
                           (A) is for relief against the Company, any Material
                  Subsidiary which is at the time a Restricted Subsidiary or
                  any subsidiary which is at the time a Restricted Subsidiary
                  and which meets both of the tests for inclusion contained in
                  subclauses (a) and (b) of Section 6.01(5)(iii) in an
                  involuntary case,

                           (B) appoints a Custodian of the Company, any Material
                  Subsidiary which is at the time a Restricted Subsidiary or any
                  subsidiary which is at the time a Restricted Subsidiary and
                  which meets both of the tests for inclusion contained in
                  subclauses (a) and (b) of Section 6.01(5)(iii) for all or
                  substantially all of its property, or

                           (C) orders the liquidation of the Company, any
                  Material Subsidiary which is at the time a Restricted
                  Subsidiary or any subsidiary which is at the time a
                  Restricted Subsidiary and which meets both of the tests for
                  inclusion contained in subclauses (a) and (b) of Section
                  6.01(5)(iii), and the order or decree remains unstayed and in
                  effect for 60 days.

         The term "Bankruptcy Law" means title 11, U.S. Code or any similar
Federal or state law for the relief of debtors. The term "Custodian" means any
receiver, trustee, assignee, liquidator or similar official under any Bankruptcy
Law.

         A Default under clause (3) (other than Defaults under Section 4.06
(except for a Default in connection with a Restricted Payment pursuant to
clauses (iii) and (v) of the definition of Restricted Payment), 4.09, or 5.01,
which Defaults shall be Events of Default with the notice but without the
passage of time specified in this paragraph) is not an Event of Default until
the Trustee or the Holders of at least 25% in principal amount of the then
outstanding Securities notify the Company of the Default and the Company does
not cure the Default within 60 days (10 days with respect to a Default under
Section 4.14) after receipt of the notice. The notice must specify the Default,
demand that it be remedied and state that the notice is a "Notice of Default."

SECTION 6.02      ACCELERATION.

         If an Event of Default (other than an Event of Default with respect to
the Company specified in clauses (6) and (7) of Section 6.01) occurs and is
continuing, the Trustee by written notice to the Company, or the Holders of at
least 25% in aggregate principal amount of the then outstanding Securities by
written notice to the Company and the Trustee, may declare the unpaid principal
of and accrued interest on


                                       45
<PAGE>   56
all the Securities to be due and payable. Upon such declaration of acceleration,
the aggregate principal amount of and all accrued and unpaid interest on the
outstanding Securities shall be due and payable immediately. If an Event of
Default with respect to the Company specified in clause (6) or (7) of Section
6.01 occurs, such an amount shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder. The Holders of a majority in principal amount of the then outstanding
Securities by notice to the Trustee may rescind an acceleration and its
consequences (except when there exists a Default consisting of nonpayment of
principal or interest on the Securities except principal or interest due solely
by reason of such acceleration) if the rescission would not conflict with any
judgment or decree.

SECTION 6.03      OTHER REMEDIES.

         If an Event of Default occurs and is continuing, the Trustee may pursue
any available remedy by proceeding at law or in equity to collect the payment of
principal of or interest on the Securities or to enforce the performance of any
provision of the Securities or this Indenture.

         The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Securityholder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

SECTION 6.04      WAIVER OF PAST DEFAULTS.

         Subject to Sections 6.07 and 9.02, the Holders of a majority in
principal amount of the then outstanding Securities by notice to the Trustee may
waive an existing Default or Event of Default and its consequences except a
continuing Default or Event of Default in the payment of the principal of or
interest on any Security. When a Default is waived, it is cured and stops
continuing. No waiver shall extend to any subsequent or other Default or impair
any right consequent thereon.

SECTION 6.05      CONTROL BY MAJORITY.

         The Holders of a majority in principal amount of the then outstanding
Securities may direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or exercising any trust or power
conferred on it.


                                       46
<PAGE>   57
However, the Trustee may refuse to follow any direction that conflicts with law
or this Indenture, is unduly prejudicial to the rights of other Securityholders
or would involve the Trustee in personal liability.

SECTION 6.06      LIMITATION ON SUITS.

         A Securityholder may not pursue any remedy with respect to this
Indenture or the Securities unless:

                  (1) the Holder gives to the Trustee notice of a continuing
         Event of Default;

                  (2) the Holders of at least 25% in principal amount of the
         then outstanding Securities make a request to the Trustee to pursue the
         remedy;

                  (3) such Holder or Holders offer to the Trustee indemnity
         satisfactory to the Trustee against any loss, liability or expense;

                  (4) the Trustee does not comply with the request within 60
         days after receipt of the request and the offer of indemnity; and

                  (5) during such 60-day period the Holders of a majority in
         principal amount of the then outstanding Securities do not give the
         Trustee a direction inconsistent with the request.

         A Securityholder may not use this Indenture to prejudice the rights of
another Securityholder or to obtain a preference or priority over another
Securityholder.

SECTION 6.07      RIGHTS OF HOLDERS TO RECEIVE PAYMENT.

         Notwithstanding any other provision of this Indenture, the right of any
Holder of a Security to receive payment of principal and interest on the
Security, on or after the respective due dates expressed in the Security, or to
bring suit for the enforcement of any such payment on or after such respective
dates, shall not be impaired or affected without the consent of the Holder.

SECTION 6.08      COLLECTION SUIT BY TRUSTEE.

         If an Event of Default specified in Section 6.01(1) or (2) occurs and
is continuing, the Trustee may recover judgment in its own name and as trustee
of an


                                       47
<PAGE>   58
express trust against the Company for the whole amount of principal and interest
remaining unpaid on the Securities and interest on overdue principal and
interest and such further amount as shall be sufficient to cover the costs and,
to the extent lawful, expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

SECTION 6.09      TRUSTEE MAY FILE PROOFS OF CLAIM.

         The Trustee may file such proofs of claim and other papers or documents
as may be necessary or advisable in order to have the claims of the Trustee and
the Securityholders allowed in any judicial proceedings relative to the Company,
its creditors or its property. Nothing contained herein shall be deemed to
authorize the Trustee to authorize or consent to or accept or adopt on behalf of
any Securityholder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Securityholder in
any such proceeding.

SECTION 6.10      PRIORITIES.

         If the Trustee collects any money pursuant to this Article, it shall
pay out the money in the following order:

         First:   to the Trustee for amounts due under Section 7.07;

         Second:  to holders of Senior Debt to the extent required by Article
                  11;

         Third:   to Securityholders for amounts due and unpaid on the
                  Securities for principal and interest, ratably, without
                  preference or priority of any kind, according to the amounts
                  due and payable on the Securities for principal and interest,
                  respectively; and

         Fourth:  to the Company.

         The Trustee may fix a record date and payment date for any payment to
Securityholders.

SECTION 6.11      UNDERTAKING FOR COSTS.

         In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a


                                       48
<PAGE>   59
court in its discretion may require the filing by any party litigant in the suit
of an undertaking to pay the costs of the suit, and the court in its discretion
may assess reasonable costs, including reasonable attorneys fees, against any
party litigant in the suit, having due regard to the merits and good faith of
the claims or defenses made by the party litigant. This Section does not apply
to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit
by Holders of more than 10% in principal amount of the then outstanding
Securities.


                                    ARTICLE 7

                                   THE TRUSTEE

         The Trustee hereby accepts the trust imposed upon it by this Indenture
and covenants and agrees to perform the same, as herein expressed.

SECTION 7.01      DUTIES OF THE TRUSTEE.

         (a) If an Event of Default has occurred and is continuing, the Trustee
shall exercise such of the rights and powers vested in it by this Indenture and
use the same degree of care and skill in its exercise as a prudent person would
exercise or use under the circumstances in the conduct of his or her own
affairs.

         (b) Except during the continuance of an Event of Default:

                  (1) The Trustee need perform only those duties that are
         specifically set forth in this Indenture and no others; and

                  (2) In the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture. However, in the case of any such opinions or
         certificates which by any provision hereof are specifically required to
         be furnished to the Trustee, the Trustee shall examine the
         certificates and opinions to determine whether or not they conform to
         the requirements of this Indenture.

         (c) The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own willful
misconduct, except that:


                                       49
<PAGE>   60
                  (1) This paragraph does not limit the effect of paragraph (b)
         of this Section;

                  (2) The Trustee shall not be liable for any error of judgment
         made in good faith by a Trust Officer, unless it is proved that the
         Trustee was negligent in ascertaining the pertinent facts; and

                  (3) The Trustee shall not be liable with respect to any action
         it takes or omits to take in good faith in accordance with a direction
         received by it pursuant to Section 6.05.

         (d) Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b) and (c) of this Section.

         (e) The Trustee may refuse to perform any duty or exercise any right or
power unless it receives indemnity satisfactory to it against any loss,
liability or expense.

         (f) The Trustee shall not be liable for interest on any money received
by it except as the Trustee may agree in writing with the Company. Money held in
trust by the Trustee need not be segregated from other funds except to the
extent required by law.

SECTION 7.02      RIGHTS OF THE TRUSTEE.

         (a) The Trustee may rely on any document believed by it to be genuine
and to have been signed or presented by the proper person. The Trustee need not
investigate any fact or matter stated in such a document.

         (b) Before the Trustee acts or refrains from acting, it may require an
Officers' Certificate, an Opinion of Counsel or both. The Trustee shall not be
liable for any action it takes or omits to take in good faith in reliance on
such Officers' Certificate or Opinion of Counsel.

         (c) The Trustee may act through agents and shall not be responsible for
the misconduct or negligence of any agent appointed with due care.

         (d) The Trustee shall not be liable for any action it takes or omits to
take in good faith which it believes to be authorized or within its rights or
powers.


                                       50
<PAGE>   61
         (e) The Trustee may consult with counsel of its selection and the
advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted
by it hereunder in good faith and in reliance thereon.

         (f) The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the Holders pursuant to this Indenture, unless such Holders shall have
offered to the Trustee reasonable security or indemnity against the costs,
expenses and liabilities which might be incurred by it in compliance with such
request or direction.

SECTION 7.03      INDIVIDUAL RIGHTS OF THE TRUSTEE.

         The Trustee in its individual or any other capacity may become the
owner or pledgee of Securities and may otherwise deal with the Company or an
Affiliate with the same rights it would have if it were not Trustee. Any Agent
may do the same with like rights. However, the Trustee is subject to Sections
7.10 and 7.11.

SECTION 7.04      TRUSTEE'S DISCLAIMER.

         The Trustee makes no representation as to the validity or adequacy of
this Indenture or the Securities, it shall not be accountable for the Company's

statement in the Indenture or any statement in the Securities other than its
authentication.

SECTION 7.05      NOTICE OF DEFAULTS.

         If a Default occurs and is continuing and if it is known to the
Trustee, the Trustee shall mail to each Securityholder a notice of the Default
within 90 days after it occurs. Except in the case of a Default in payment on
any Security, the Trustee may withhold the notice if and so long as a committee
of its Trust Officers in good faith determines that withholding the notice is in
the interests of Securityholders.

SECTION 7.06      REPORTS BY THE TRUSTEE TO HOLDERS.

         Within 60 days after the reporting date stated in Section 10.10, the
Trustee shall mail to Securityholders a brief report dated as of such reporting

transmitted). The Trustee also shall comply with TIA Section 313(b)(2). The
Trustee shall also transmit by mail all reports as required by TIA Section
313(c).

         A copy of each report at the time of its mailing to Securityholders
shall be filed with the SEC and each stock exchange on which the Securities are
listed. The Company shall promptly notify the Trustee when the Securities are
listed on any stock exchange.

SECTION 7.07      COMPENSATION AND INDEMNITY.

         The Company shall pay to the Trustee from time to time such
compensation as shall be agreed in writing between the Company and the Trustee
for its services hereunder. The Trustee's compensation shall not be limited by
any law on compensation of a trustee of an express trust. The Company shall
reimburse the Trustee upon request for all reasonable out-of-pocket expenses
incurred by it. Such expenses may include the reasonable compensation and
out-of-pocket expenses of the Trustee's agents and counsel.

         The Company shall indemnify each of the Trustee and any predecessor
Trustee against any and all loss, damage, claim, liability or expense, including
taxes (other than taxes based on the income, revenues or assets of the Trustee),
incurred by it in connection with the acceptance or administration of the trust
or trusts hereunder except as set forth in the next paragraph. The Trustee shall
notify the Company promptly of any claim for which it may seek indemnity. The
Company shall defend the claim with counsel designated by the Company, who may
be outside counsel to the Company but shall in all events be reasonably
satisfactory to the Trustee, and the Trustee shall cooperate in the defense. In
addition, if the Company does not so defend the Trustee or if at any time the
counsel so selected is ethically prohibited from representing the Trustee
(whether because of a conflict of interest or the provisions of the TIA) or is
not reasonably satisfactory to the Trustee, then the Trustee may retain one
separate counsel and, if deemed advisable by such counsel, local counsel, and
the Company shall pay the reasonable fees and expenses of such separate counsel
and local counsel. The indemnification herein extends to any settlement,
provided that the Company will not be liable for any settlement made without its
consent, provided further that such consent will not be unreasonably withheld.

         The Company need not reimburse any expense or indemnify against any
loss or liability incurred by the Trustee through negligence or bad faith.


                                       52
<PAGE>   63
         To secure the Company's payment obligations in this Section, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee, except that held in trust to pay principal and
interest on Securities.

         When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(6) or (7) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

         The provisions of this Section 7.07 shall survive the termination of
this Indenture.

SECTION 7.08      REPLACEMENT OF THE TRUSTEE.

         A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section.

         The Trustee may resign by so notifying the Company. The Holders of a
majority in principal amount of the then outstanding Securities may remove the
Trustee by so notifying the removed Trustee and the Company and may appoint a
successor Trustee with the Company's consent. The Company may remove the Trustee
if:

                  (1) the Trustee fails to comply with Section 7.10;

                  (2) the Trustee is adjudged a bankrupt or an insolvent or an
         order for relief is entered with respect to the Trustee under any
         Bankruptcy Law;

                  (3) a Custodian or public officer takes charge of the Trustee
         or its property; or

                  (4) the Trustee becomes incapable of acting.

         If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the then outstanding Securities may appoint
a successor Trustee to replace the successor Trustee appointed by the Company.


                                       53
<PAGE>   64
         If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holders of at least 10% in principal amount of the then outstanding Securities
may petition any court of competent jurisdiction for the appointment of a
successor Trustee.

         If the Trustee fails to comply with Section 7.10, any Securityholder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Securityholders. The removed or retiring Trustee shall promptly
transfer all property held by it as Trustee to the successor Trustee, subject to
the lien provided for in Section 7.07. Notwithstanding the replacement of the
Trustee pursuant to this Section 7.08, the Company's obligations under Section
7.07 hereof shall continue for the benefit of the retiring Trustee with respect
to expenses and liabilities incurred by it prior to such replacement.

SECTION 7.09      SUCCESSOR TRUSTEE BY MERGER, ETC.

         If the Trustee consolidates with, merges or converts into, or transfers
all or substantially all of its corporate trust business to, another
corporation, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

SECTION 7.10      ELIGIBILITY; DISQUALIFICATION.

         This Indenture shall always have a Trustee who satisfies the
requirements of TIA Section 310(a)(1). The Trustee shall always have a combined
capital and surplus as stated in Section 10.10. The Trustee is subject to TIA
Section 310(b) regarding the disqualification of a trustee upon acquiring a
conflicting interest.

SECTION 7.11      PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

         The Trustee shall comply with TIA Section 311(a), excluding any
creditor relationship set forth in TIA Section 311(b). A Trustee who has
resigned or been removed shall be subject to TIA Section 311(a) to the extent
indicated therein.

                                    ARTICLE 8

                     SATISFACTION AND DISCHARGE OF INDENTURE

SECTION 8.01      TERMINATION OF COMPANY'S OBLIGATIONS.

         (a) This Indenture shall cease to be of further effect (except that the
Company's obligations under Section 7.07 and the Trustee's and Paying Agent's
obligations under Section 8.03 shall survive) when all outstanding Securities
thereto fore authenticated and issued have been delivered (other than destroyed,
lost or stolen Securities that have been replaced or paid) to the Trustee for
cancellation and the Company has paid all sums payable hereunder. In addition,
the Company may terminate its obligations under this Indenture (except the
Company's obligations under Sections 7.07 and the Trustee's and Paying Agent's
obligations under Section 8.03) if, under terms satisfactory to the Trustee:

                  (1) the Securities have either become due and payable or are
         by their terms due and payable within one year (or scheduled for
         redemption within one year); and

                  (2) the Company irrevocably deposits in trust with the Trustee
         money or United States Government Obligations (defined below in this
         Section 8.01), or a combination thereof, sufficient, without
         consideration of the reinvestment of interest, in the opinion of the
         chief financial officer of the Company expressed in a written
         certificate delivered to the Trustee, to pay principal and interest on
         the Securities to maturity or upon redemption, as the case may be. The
         Company may make the deposit only during the one-year period and only
         if Article 11 permits it.

However, the Company's obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07,
4.01, 7.07, 7.08, and 8.04 and the Trustee's and Paying Agent's obligations
under Section 8.03 shall survive until the Securities are no longer outstanding.
Thereafter, only the Company's obligations in Sections 7.07 and the Trustee's
and Paying Agent's obligations under Section 8.03 shall survive.

         After a deposit made pursuant to this Section 8.01, the Trustee, upon
request, shall acknowledge in writing the discharge of the Company's obligations
under this Indenture except for those surviving obligations specified above.


                                       55
<PAGE>   66
         In addition, the Company may elect to have either paragraph (b) or
paragraph (c) below be applied to the outstanding Securities upon compliance
with the conditions set forth in paragraph (d).

         (b) Upon the Company's exercise under the last sentence of paragraph
(a) of the option applicable to this paragraph (b), the Company shall be deemed
to have been released and discharged from its obligations with respect to the
outstanding Securities on the date the conditions set forth below are satisfied
("defeasance"). For this purpose, defeasance means that the Company shall be
deemed to have paid and discharged the entire indebtedness represented by the
outstanding Securities, which shall thereafter be deemed to be "outstanding"
only for the purposes of the Sections of and matters under this Indenture
referred to in (i) and (ii) below, and to have satisfied all its other
obligations under such Securities and this Indenture insofar as such Securities
are concerned (and the Trustee, at the expense of the Company, shall execute
proper instruments acknowledging the same), except for the following, which
shall survive until otherwise terminated or discharged hereunder: (i) the rights
of Holders of outstanding Securities to receive, solely from the trust fund
described in paragraph (d) below and as more fully set forth in such paragraph,
payments in respect of the principal of and interest on such Securities when
such payments are due, (ii) the Company's obligations with respect to such
Securities under Sections 2.03, 2.05, 2.06, 2.07 and 4.04, and, with respect to
the Trustee, under Section 7.07, (iii) the rights, powers, trusts, duties and
immunities of the Trustee hereunder and (iv) this Section 8.01 and Sections 8.03
and 8.04. Subject to compliance with this Section 8.01, the Company may exercise
its option under this paragraph (b) notwithstanding the prior exercise of its
option under paragraph (c) below with respect to the Securities.

         (c) Upon the Company's exercise under the last sentence of paragraph
(a) of the option applicable to this paragraph (c), the Company shall be
released and discharged from its obligations under any covenant contained in
Article 4 (except for Sections 4.01 and 4.04) and Article 5 with respect to the
outstanding Securities on and after the date the conditions set forth below are
satisfied ("covenant defeasance"), and the Securities shall thereafter be deemed
to be not "outstanding" for the purpose of any direction, waiver, consent or
declaration or act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed "outstanding"
for all other purposes hereunder. For this purpose, such covenant defeasance
means that, with respect to the outstanding Securities, the Company may omit to
comply with and shall have no liability in respect of any term, condition or
limitation set forth in any such covenant, whether directly or indirectly, by
reason of any reference elsewhere herein to any such covenant or by reason of
any


                                       56
<PAGE>   67
reference in any such covenant to any other provision herein or in any other
document and such omission to comply shall not constitute a Default or an Event
of Default under Section 6.01 but, except as specified above, the remainder of
this Indenture (including without limitation obligations set forth in Sections
8.03 and 8.04 hereof) and such Securities shall be unaffected thereby.

         (d) The following shall be the conditions to the application of either
paragraph (b) or (c) above to the outstanding Securities:

                  (1) the Company has irrevocably deposited in trust with the
         Trustee or, at the option of the Trustee, with a trustee, satisfactory
         to the Trustee and the Company under the terms of an irrevocable trust
         agreement in form and substance satisfactory to the Trustee, money or
         United States Government Obligations, or a combination thereof,
         sufficient, without consideration of the reinvestment of interest, in
         the opinion of the chief financial officer of the Company expressed in
         a written certificate delivered to the Trustee, to pay, at maturity,
         principal and interest on the Securities; provided that (i) the trustee
         of the irrevocable trust shall have been irrevocably instructed to pay
         such money or the proceeds of such United States Government
         Obligations to the Trustee, (ii) the Trustee shall have been
         irrevocably instructed to apply such money or the proceeds of such
         United States Government Obligations to the payment of said principal
         and interest with respect to the Securities, and (iii) such deposit
         does not violate Article 11 hereof;

                  (2) the Company has delivered to the Trustee an Officers'
         Certificate stating that (A) all conditions provided for relating to
         either the legal defeasance under paragraph (b) above or the covenant
         defeasance under paragraph (c) above, as the case may be, have been
         complied with and (B) if any other Indebtedness of the Company shall
         then be outstanding, such legal defeasance or covenant defeasance will
         not violate the provisions of the agreements or instruments evidencing
         such Indebtedness;

                  (3) no Default or Event of Default shall have occurred and be
         continuing on the date of such deposit;

                  (4) such legal defeasance or covenant defeasance shall not
         result in a breach or violation of, or constitute a Default or Event of
         Default under, this Indenture or any other agreement or instrument to
         which the Company is a party or by which it is bound;


                                       57
<PAGE>   68
                  (5) in the case of an election under paragraph (b) above, the
         Company shall have delivered to the Trustee an Opinion of Counsel from
         nationally recognized counsel reasonably acceptable to the Trustee
         stating that (x) the Company has received from, or there has been
         published by, the Internal Revenue Service a ruling or (y) since the
         date of this Indenture, there has been a change in the applicable
         federal income tax law, in either case to the effect that the Holders
         of the outstanding Securities will not recognize income, gain or loss
         for federal income tax purposes as a result of such defeasance and will
         be subject to federal income tax on the same amount and in the same
         manner and at the same time as would have been the case if such
         defeasance had not occurred; and

                  (6) in the case of an election under paragraph (c) above, the
         Company shall have delivered to the Trustee an Opinion of Counsel from
         nationally recognized counsel reasonably acceptable to the Trustee (i)
         to the effect that the Holders of the outstanding Securities will
         recognize income, gain or loss for federal income tax purposes in the
         same amount and in the same manner and at the same time as would have
         been the case if such covenant defeasance had not occurred or (ii) that
         the Company has received from, or there has been published by, the
         Internal Revenue Service a ruling to the foregoing effect.

         After such irrevocable deposit made pursuant to this Section 8.01 and
satisfaction of the other conditions set forth herein, the Trustee upon request
shall acknowledge in writing the discharge of the Company's obligations under
this Indenture except for those surviving obligations specified above.

         As used herein, "United States Government Obligations" means
obligations for which the full faith and credit of the United States of America
is pledged and which are not callable at the issuer's option.

SECTION 8.02      APPLICATION OF TRUST MONEY.

         The Trustee shall hold in trust money or United States Government
Obligations deposited with it pursuant to Section 8.01. It shall apply the
deposited money and the money from United States Government Obligations through
the Paying Agent and in accordance with this Indenture to the payment of
principal and interest on the Securities. Money and securities so held in trust
are not subject to Article 11.


                                       58
<PAGE>   69
SECTION 8.03      REPAYMENT TO COMPANY.

         The Trustee and the Paying Agent shall promptly pay to the Company upon
written request any excess money or securities held by them at any time.

         The Trustee and the Paying Agent shall pay to the Company upon written
request any money held by them for the payment of principal or interest that
remains unclaimed for two years after the date upon which such payment shall
have become due; provided, however, that the Company shall have first caused
notice of such payment to the Company to be mailed to each Securityholder
entitled thereto no less than 30 days prior to such payment. After payment to
the Company, Securityholders entitled to the money must look to the Company for
payment as general creditors unless an applicable abandoned property law
designates another Person.

SECTION 8.04      REINSTATEMENT.

         If the Trustee or Paying Agent is unable to apply any money in
accordance with Section 8.02 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company's obligations under this Indenture and the Securities
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 8.01 until such time as the Trustee or Paying Agent is permitted to
apply all such money in accordance with Section 8.02; provided, however, that if
the Company makes any payment of interest on or principal of any Security
following the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Securities to receive such payment from the
money held by the Trustee or Paying Agent.


                                    ARTICLE 9

                                   AMENDMENTS

SECTION 9.01      WITHOUT THE CONSENT OF HOLDERS.

         The Company and the Trustee may amend this Indenture or the Securities
without notice to or the consent of any Securityholder:

                  (1) to cure any ambiguity, defect or inconsistency;

                  (2) to comply with Section 5.01;


                                       59
<PAGE>   70
                  (3) to provide for uncertificated Securities in addition to
         certificated Securities;

                  (4) to make any change that does not adversely affect the
         legal rights hereunder of any Securityholder;

                  (5) to surrender any right or power herein conferred upon the
         Company; or

                  (6) to modify, eliminate or add to the provisions of this
         Indenture to such extent as shall be necessary to effect the
         qualification of the Indenture under the TIA, or under any similar
         federal statute hereafter enacted.

SECTION 9.02      WITH THE CONSENT OF HOLDERS.

         Subject to Section 6.07, the Company and the Trustee may amend this
Indenture or the Securities with the written consent of the Holders of at least
a majority in principal amount of the then outstanding Securities.

         Subject to Sections 6.04 and 6.07, the Holders of a majority in
principal amount of the Securities then outstanding may also waive compliance in
a particular instance by the Company with any provision of this Indenture or the
Securities.

         However, without the consent of each Securityholder affected, an
amendment or waiver under this Section may not:

                  (1) reduce the amount of Securities whose Holders must consent
         to an amendment, supplement or waiver;

                  (2) reduce the rate of or change the time for payment of
         interest on any Security;

                  (3) reduce the principal of or change the fixed maturity of
         any Security or alter the redemption provisions with respect thereto;

                  (4) make any Security payable in money other than that stated
         in the Security;

                  (5) make any change in Sections 6.04, 6.07 or 9.02 (this
         sentence); or


                                       60
<PAGE>   71
                  (6) waive a default in the payment of the principal of, or
         interest on, any Security.

         To secure a consent of the Holders under this Section, it shall not be
necessary for the Holders to approve the particular form of any proposed
amendment or waiver, but it shall be sufficient if such consent approves the
substance thereof.

         After an amendment or waiver under this Section becomes effective, the
Company shall mail to Securityholders a notice briefly describing the amendment
or waiver.

         After the issuance of any Securities, an amendment under this Section
or under Section 9.01 may not make any change that adversely affects in any
material respect the rights under Article 11 of the holders of Senior Debt,
unless such holders consent to the change.

SECTION 9.03      COMPLIANCE WITH THE TRUST INDENTURE ACT.

         Every amendment to this Indenture or the Securities shall be set forth
in a supplemental indenture that complies with the TIA as then in effect.

SECTION 9.04      REVOCATION AND EFFECT OF CONSENTS.

         Until an amendment or waiver becomes effective, a consent to it by a
Holder of a Security is a continuing consent by the Holder and every subsequent
Holder of a Security or portion of a Security that evidences the same debt as
the consenting Holder's Security, even if notation of the consent is not made on
any Security. However, any such Holder or subsequent Holder may revoke the
consent as to his or her Security or portion of a Security if the Trustee
receives the notice of revocation before the date on which the Trustee receives
an Officers' Certificate certifying that the Holders of the requisite principal
amount of Securities have consented to the amendment or waiver.

         The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any amendment or
waiver. If a record date is fixed, then notwithstanding the provisions of the
immediately preceding paragraph, those persons who were Holders at such record
date (or their duly designated proxies), and only those persons, shall be
entitled to consent to such amendment or waiver or to revoke any consent
previously given, whether or not such persons continue to be Holders after such
record date. No consent shall be valid or


                                       61
<PAGE>   72
effective for more than 90 days after such record date unless consents from
Holders of the principal amount of Securities required hereunder for such
amendment or waiver to be effective shall have also been given and not revoked
within such 90-day period.

         After an amendment or waiver becomes effective it shall bind every
Securityholder, unless it is of the type described in any of clauses (1) through
(6) of Section 9.02. In such case, the amendment or waiver shall bind each
Holder of a Security who has consented to it.

SECTION 9.05      NOTATION ON OR EXCHANGE OF SECURITIES.

         The Trustee may place an appropriate notation about an amendment or
waiver on any Security thereafter authenticated. The Company in exchange for all
Securities may issue and the Trustee shall authenticate new Securities that
reflect the amendment or waiver.

SECTION 9.06      THE TRUSTEE PROTECTED.

         The Trustee shall sign all supplemental indentures, except that the
Trustee need not sign any supplemental indenture that adversely affects its
rights. The Company may not sign an amendment or supplement until the Board of
Directors approves it. The Trustee, subject to Sections 7.01 and 7.02, shall be
entitled to receive, and shall be fully protected in relying upon, an Opinion of
Counsel stating that any amendment, supplement or waiver is authorized or
permitted by this Indenture and complies with the provisions of this Article 9.


                                   ARTICLE 10

                               GENERAL PROVISIONS

SECTION 10.01     TRUST INDENTURE ACT CONTROLS.

         If any provision of this Indenture limits, qualifies or conflicts with
the duties imposed by TIA Section 318(c), the imposed duties shall control.

<PAGE>   73
SECTION 10.02     NOTICES.

         Any notice or communication by the Company or the Trustee to the other
is duly given if in writing and delivered in person or mailed by first-class
mail, with postage prepaid, to the other's address stated in Section 10.10. The
Company or the Trustee by notice to the other may designate an additional or
different address for subsequent notices or communications.

         Any notice or communication to a Securityholder shall be mailed by
first-class mail, with postage prepaid, to his or her address shown on the
register kept by the Registrar. Failure to mail a notice or communication to a
Securityholder or any defect in it shall not affect its sufficiency with respect
to other Securityholders.

         If a notice or communication is mailed in the manner provided above
within the time prescribed, it is duly given, whether or not the addressee
receives it.

         If the Company mails a notice or communication to Securityholders, it

                                  SUBORDINATION

SECTION 11.01     AGREEMENT TO SUBORDINATE.

         The Company agrees, and each Securityholder by accepting a Security
agrees, that the indebtedness evidenced by the Securities is subordinated in
right of payment, to the extent and in the manner provided in this Article, to
the prior payment in full of all Senior Debt and that the subordination is for
the benefit of the holders of Senior Debt.

SECTION 11.02     CERTAIN DEFINITIONS.

         "Debt" of any Person, means any indebtedness, contingent or otherwise,
(x) in respect of borrowed money (whether or not the recourse of the lender is

evidenced by bonds, notes, debentures or similar instruments (except any of the
foregoing that constitutes a trade payable) or (z) evidenced by letters of
credit.

         "Designated Senior Debt" means (i) Senior Debt of the Company permitted
to be incurred hereunder under any institutional credit agreement and (ii) any
other Senior Debt permitted to be incurred hereunder, the principal amount of
which is $25 million or more.

<PAGE>   78

representative for an issue of Senior Debt.

         "Senior Debt" means all present and future Debt created, incurred,
assumed or guaranteed (to the extent of the guarantee) by the Company (and all
renewals, extensions or refundings thereof), unless the instrument under which
such Debt is created, incurred, assumed or guaranteed provides that such Debt is
not senior or superior in right of payment to the Securities. Notwithstanding
anything to the contrary in the foregoing, Senior Debt shall not include (i) any
Debt of the Company to any of its subsidiaries, (ii) any Debt of the Company or
guarantees of Debt of the Company which by its terms or the terms of the
instrument creating or evidencing it expressly provides that such Debt or
guarantee is expressly subordinated in right of payment to any other Debt of the
Company, (iii) the Outstanding Debentures or (iv) guarantees by the Company of
Debt (a) outstanding at the date hereof or (b) which may be outstanding in the
future, except that Senior Debt shall include any present and future guarantees
that provide by their terms that they constitute Senior Debt and the Repayment
Guaranty (Limited), dated as of June 30, 1992, from the Company to Bank One,
Arizona, NA with respect to certain indebtedness of The Villages at Desert
Hills, Inc. The Securities are not senior or superior in right of payment to the
Outstanding Debentures and rank pari passu in right of payment to the
Outstanding Debentures.

SECTION 11.03     LIQUIDATION; DISSOLUTION; BANKRUPTCY.

         Upon any distribution to creditors of the Company in a liquidation or
dissolution of the Company or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or its property:

                  (1) holders of Senior Debt shall be entitled to receive
         payment in full in cash of the principal of and interest (including
         interest accruing after the commencement of any such proceeding) to the
         date of payment on the Senior Debt before Securityholders shall be
         entitled to receive any payment of principal of or interest on
         Securities, except to the extent that Securityholders receive
         securities that are subordinated to Senior Debt to at least the same
         extent as the Securities; and

                  (2) until the Senior Debt is paid in full in cash, any
         distribution to which Securityholders would be entitled but for this
         Article shall be made to holders of Senior Debt as their interests may
         appear, except to the extent that


                                       68
<PAGE>   79
         Securityholders receive securities that are subordinated to Senior Debt
         to at least the same extent as the Securities.

         For purposes of this Article 11, a distribution may consist of cash,
securities or other property, by set-off or otherwise.

SECTION 11.04     DEFAULT ON DESIGNATED SENIOR DEBT.

         The Company may not pay principal of or interest on the Securities and
may not acquire from the Trustee or any Securityholder any Securities for cash
or property (other than securities that are subordinated to at least the same
extent as the Securities are subordinated to Senior Debt) until all Senior Debt
has been paid in full if:

                  (i) a default in the payment of any principal or other
         obligations with respect to Designated Senior Debt occurs and is
         continuing beyond any applicable grace period in the agreement,
         indenture or other document governing such Designated Senior Debt; or

                  (ii) a default, other than a payment default, on Designated
         Senior Debt occurs and is continuing that then permits holders of the
         Designated Senior Debt to accelerate its maturity and the Trustee
         receives a notice of the default from a person who may give it pursuant
         to Section 11.12 hereof requesting that payment of principal or
         interest with respect to the Securities be prohibited.

The Company may and shall resume payments on the Securities and may acquire them
upon the earlier of:

                  (1) the date upon which the default is cured or waived, or

                  (2) (2) in the case of a default and notice referred to in
         Section 11.04(ii) hereof, the passage of 179 days after such notice is
         received (the "Payment Blockage Period"),

if this Article otherwise permits the payment or acquisition at the time of such
payment or acquisition.

         Only one Payment Blockage Period may be commenced within any
consecutive 365-day period with respect to the Securities. For all purposes of
this Section 11.04, no nonpayment default that existed or was continuing on the
date of com-


                                       69
<PAGE>   80
mencement of any Payment Blockage Period shall be, or be made, the basis for the
commencement of a second Payment Blockage Period unless such default shall have
been cured or waived for a period of not less than 180 days.

SECTION 11.05     ACCELERATION OF SECURITIES.

         If payment of the Securities is accelerated because of an Event of
Default, the Company shall promptly notify holders of Senior Debt of the
acceleration. The Company shall pay the Securities when 179 days pass after the
acceleration occurs if this Article permits the payment at that time; provided,
however, that if no Senior Debt is outstanding at the time of such acceleration,
the Company shall pay the Securities in accordance with the provisions of
Article 6.

SECTION 11.06     WHEN DISTRIBUTIONS MUST BE PAID OVER.

         In the event that the Company shall make any payment to the Trustee on
account of the principal or interest on the Securities at a time when the
Trustee shall have received notice in accordance with Section 11.12 that such
payment is prohibited by Section 11.03 or 11.04, such payment shall be held by
the Trustee in trust for the benefit of, and shall forthwith be paid over and
delivered, upon written request to, the holders of Senior Debt (pro rata as to
each of such holders on the basis of the respective amounts of Senior Debt held
by them) or their Representative under the indenture or other agreement (if any)
pursuant to which Senior Debt may have been issued, as their respective
interests may appear, for application to the payment of all Senior Debt
remaining unpaid to the extent necessary to pay all Senior Debt in full in
accordance with its terms, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Debt.

         If a distribution is made to Securityholders that because of this
Article should not have been made to them, the Securityholders who receive the
distribution shall hold it in trust for holders of Senior Debt and, upon written
request, pay it over to them as their interests may appear for application to
the payment of all Senior Debt remaining unpaid to the extent necessary to pay
all Senior Debt in full in accordance with its terms, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Debt.


                                       70
<PAGE>   81
SECTION 11.07     NOTICE BY THE COMPANY.

         The Company shall promptly notify the Trustee and the Paying Agent of
any facts known to the Company that would cause a payment of principal of or
interest on the Securities to violate this Article, but failure to give such
notice shall not affect the subordination of the Securities to the Senior Debt
provided in this Article. Nothing in this Article shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 7.07.

SECTION 11.08     SUBROGATION.

         After all Senior Debt is paid in full and until the Securities are paid
in full, Securityholders shall be subrogated to the rights of holders of Senior
Debt to receive distributions applicable to Senior Debt to the extent that
distributions otherwise payable to the Securityholders have been applied to the
payment of Senior Debt. A distribution made under this Article to holders of
Senior Debt which otherwise would have been made to Securityholders is not, as
between the Company and Securityholders, a payment by the Company on Senior
Debt.

SECTION 11.09     RELATIVE RIGHTS.

         This Article defines the relative rights of Securityholders and holders
of Senior Debt. Nothing in this Indenture shall:

                  (1) impair, as between the Company and Securityholders, the
         obligation of the Company, which is absolute and unconditional, to pay
         principal of and interest on the Securities in accordance with their
         terms;

                  (2) affect the relative rights of Securityholders and
         creditors of the Company, other than their rights in relation to
         holders of Senior Debt; or

                  (3) prevent the Trustee or any Securityholder from exercising
         its available remedies upon a Default or Event of Default, subject to
         the rights of holders of Senior Debt to receive distributions otherwise
         payable to Securityholders.

         If the Company fails because of this Article to pay principal of or
interest on a Security on the due date, the failure is still a Default or Event
of Default.


                                       71
<PAGE>   82
SECTION 11.10     SUBORDINATION MAY NOT BE IMPAIRED BY THE
                  COMPANY.

         No right of any holder of Senior Debt to enforce the subordination of
the indebtedness evidenced by the Securities shall be impaired by any act or
failure to act by the Company or by its failure to comply with this Indenture.

SECTION 11.11     DISTRIBUTION OR NOTICE TO THE REPRESENTATIVE.

         Whenever a distribution is to be made or a notice given to holders of
Senior Debt, the distribution may be made and the notice given to their
Representative.

         Upon any payment or distribution of assets of the Company referred to
in this Article 11, the Trustee and the Securityholders shall be entitled to
rely conclusively upon any order or decree made by any court of competent
jurisdiction or upon any certificate of such Representative (as to the Senior
Debt for which it is the Representative) or of any trustee in bankruptcy,
liquidating trustee, Custodian, receiver or agent for the purpose of
ascertaining the persons entitled to participate in such distribution, the
holders of the Senior Debt and other Debt of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article 11.

SECTION 11.12     RIGHTS OF THE TRUSTEE AND PAYING AGENT.

         Notwithstanding any provision of this Article 11 or any other provision
of this Indenture, the Trustee and Paying Agent shall not at any time be charged
with knowledge of the existence of any facts which would prohibit the making of
any payment to or by the Trustee or a Paying Agent or the taking of any other
action (pursuant to this Article 11) by the Trustee or a Paying Agent unless and
until the Trustee or such Paying Agent, as the case may be, shall have received
at its office specified in Section 10.10 written notice thereof from the
Company, a Representative or a holder of Senior Debt entitled to give such
notice and, prior to the receipt of any such written notice, the Trustee and
such Paying Agent shall be entitled in all respects conclusively to assume that
no such fact exists. The Trustee or Paying Agent may continue to make payments
on the Securities unless it receives such a notice at least three business days
prior to the date upon which payment is due.

         The Trustee shall be entitled to rely in good faith on the delivery to
it of a written notice by a Person representing himself, herself or itself to be
a Representative


                                       72
<PAGE>   83
or a holder of Senior Debt to establish that such notice has been given by a
Representative or a holder of such Senior Debt. Only the Company, a
Representative or a holder of Senior Debt that has no Representative may give
the notice.

         In the event that the Trustee determines in good faith that further
evidence is required with respect to the right of any Person as a holder of
Senior Debt to participate in any payment or distribution pursuant to this
Article 11, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Debt held by
such Person, the extent to which such Person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such
Person under this Article 11, and if such evidence is not furnished, the
Trustee may defer any payment which it may be required to make for the benefit
of such Person pursuant to the terms of the this Indenture pending judicial
determination as to the rights of such Person to receive such payment.

         The Trustee in its individual or any other capacity may hold Senior
Debt with the same rights it would have if it were not Trustee. Any Agent may do
the same with like rights.

SECTION 11.13     NO FIDUCIARY DUTY TO HOLDERS OF SENIOR DEBT.

         With respect to the holders of Senior Debt, the Trustee undertakes to
perform or to observe only such of its covenants and obligations as are
specifically set forth in this Article 11, and no implied covenants or
obligations with respect to the holders of Senior Debt shall be read into this
Indenture against the Trustee or Paying Agent. Neither the Trustee nor the
Paying Agent shall be deemed to owe any fiduciary duty to the holders of such
Senior Debt, and the Trustee shall not be liable to any holder of such Senior
Debt if it shall, in the absence of bad faith, pay over or deliver to holders of
Securities, the Company or any other person monies or assets to which any holder
of such Senior Debt shall be entitled by virtue of this Article 11 or otherwise.

         The parties have caused this Indenture to be duly executed and
attested, all as of the date first above written, signifying their agreements
contained in this Indenture.

           10 1/4% SENIOR SUBORDINATED DEBENTURE DUE FEBRUARY 15, 2010

         1. INTEREST. Del Webb Corporation, a Delaware corporation (the
"Company"), 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
February 15 and August 15 of each year, commencing August 15, 1999. Interest on
the Securities will accrue from the most recent date to which interest has been
paid or, if no interest has been paid, from the date of issuance. 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) to the Persons who are registered holders of
Securities at the close of business on the record date for the next interest
payment date even though Securities are cancelled after the record date and on
or before 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. However, the Company may pay
principal and interest by check payable in such money. It may mail an interest
check to a Holder's registered address.

         3. PAYING AGENT AND REGISTRAR. Bank of Montreal Trust Company (together
with any successor trustee under the indenture referred to below, the
"Trustee"), will act as Paying Agent and Registrar. The Company may change any
Paying Agent or Registrar without prior notice. Subject to certain limitations
in the Indenture, the Company or any of its subsidiaries may act in any such
capacity.

         4. INDENTURE. The Company issued the Securities under an Indenture
dated as of February 18, 1999 (the "Indenture") between the Company and the
Trustee. The terms of the Securities include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939
(15 U.S. Code Sections 77aaa-77bbbb) as in effect on the date of the Indenture.
The Securities are subject to, and qualified by, all such terms, certain of
which are summarized hereon, and Securityholders are referred to the Indenture
and such Act for a statement of such terms. The Securities are unsecured
general obligations of the Company limited to $200,000,000 in aggregate
principal amount. Capitalized terms not defined herein have the same meaning as
is given to them in the Indenture.

         5. OPTIONAL REDEMPTION. The Company may not redeem the Securities prior
to February 15, 2004. Thereafter, the Company may redeem all the Securities at
any time or some of them from time to time at the redemption prices (expressed
in percentages of principal amount) set forth below plus accrued interest to the
redemption date, if redeemed during the 12-month period beginning February 15 of
the years starting with the year indicated below.

</TABLE>

         6. NOTICE OF REDEMPTION. 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 or her registered address. Securities in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000. In the event of a redemption of less than all of the
Securities, the Securities will be chosen for redemption by the Trustee pro
rata, by lot or by another means that is in compliance with the requirements of
the principal national securities exchange, if any, on which the Securities are
listed. On and after the redemption date, interest ceases to accrue on
Securities or portions of them called for redemption unless the Company defaults
in the payment of the redemption price.

         If this Security is redeemed subsequent to a record date with respect
to any interest payment date specified above and on or prior to such interest
payment date, then any accrued interest will be paid to the person in whose name
this Security is registered at the close of business on such record date.

         7. CHANGE OF CONTROL. Upon a Change of Control, the Company shall make
a Change of Control Offer to purchase all outstanding Securities at a price
equal to 101% of the aggregate principal amount of the Securities, plus accrued
and unpaid interest to the date of purchase, such offer to be made as provided
in the Indenture. To accept the Change of Control Offer, the Holder hereof must
comply with the terms thereof, including surrendering this Security, with the
"Option of Holder to Elect Purchase" portion hereof completed, to the Company, a
depositary, if appointed by the Company, or a Paying Agent, at the address
specified in the notice


                                       A-5
<PAGE>   90
of the Change of Control Offer mailed to Holders as provided in the Indenture,
prior to termination of the Change of Control Offer.

         8. NET WORTH. If the Company's Consolidated Tangible Net Worth at the
end of each of any two consecutive fiscal quarters (the last day of the second
such fiscal quarter being referred to as a Deficiency Date) is less than $125
million, the Company shall offer to purchase (a "Net Worth Offer") 10% of the
principal amount of Securities originally issued under the Indenture (or such
lesser amount as may be outstanding at the time the Net Worth Offer is made) at
a purchase price equal to 100% of the aggregate principal amount thereof, plus
accrued and unpaid interest to the purchase date, such Net Worth Offer to be
made as provided in the Indenture; provided, however, that no such Net Worth
Offer shall be required if, after the Deficiency Date but prior to the timely
delivery of the Officers' Certificate required by the Indenture, capital is
contributed or otherwise paid to the Company or its Restricted Subsidiaries
sufficient to increase the Company's Consolidated Tangible Net Worth to $125
million or more. To accept the Net Worth Offer, the Holder hereof must comply
with the terms thereof, including surrendering this Security, with the "Option
of Holder to Elect Purchase" portion hereof completed, to the Company, a
depositary, if appointed by the Company, or a Paying Agent, at the address
specified in the notice of the Net Worth Offer mailed to the Holders as provided
in the Indenture, prior to termination of the Net Worth Offer. In no event
shall the Company's failure to meet the minimum Consolidated Tangible Net Worth
at the end of any fiscal quarter be counted towards the making of more than one
Net Worth Offer.

         9. SUBORDINATION. To the extent set forth in Article 11 of the
Indenture, the Securities are subordinated to Senior Debt, which means all
present or future Debt (defined below) created, incurred, assumed or guaranteed
(to the extent of the guarantee) by the Company (and any renewals, extensions or
refundings thereof), unless the instrument under which such Debt is created,
incurred, assumed or guaranteed provides that such Debt is not senior or
superior in right of payment to the Securities. Notwithstanding anything to the
contrary in the foregoing, Senior Debt shall not include (i) any Debt of the
Company to any of its subsidiaries, (ii) any Debt of the Company or guarantees
of Debt of the Company which by its terms or the terms of the instrument
creating or evidencing it expressly provides that such Debt or guarantee is
expressly subordinated in right of payment to any other Debt of the Company,
(iii) the Outstanding Debentures or (iv) guarantees by the Company of Debt (a)
outstanding at the date of the Indenture or (b) which may be outstanding in the
future, except that Senior Debt shall include any present and future guarantees
that provide by their terms that they constitute Senior Debt and the Repayment
Guaranty (Limited) dated as of June 30, 1992, from the Company to Bank One,


                                       A-6

Arizona, NA with respect to certain indebtedness of The Villages at Desert
Hills, Inc. Debt of any Person is any indebtedness, contingent or otherwise, (x)
in respect of borrowed money (whether or not the recourse of the lender is to
the whole of the assets of such Person or only to a portion thereof), (y)
evidenced by bonds, notes, debentures or similar instruments (except any of the
foregoing that constitutes a trade payable) or (z) evidenced by letters of
credit. To the extent provided in the Indenture, Senior Debt must be paid
before the Securities may be paid. The Company agrees, and each Securityholder
by accepting a Security agrees, to the subordination and authorizes the Trustee
to give it effect.

         10. DENOMINATIONS, TRANSFER, EXCHANGE. The Securities are in registered
form without coupons in denominations of $1,000 and integral multiples of
$1,000. The transfer of Securities may be registered and Securities may be
exchanged as provided in the Indenture. As a condition of transfer, the
Registrar may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and the Company may require a Holder to pay
any taxes and fees required by law or permitted by the Indenture. The Registrar
need not exchange or register the transfer of any Security or portion of a
Security selected for redemption. Also, it need not exchange or register the
transfer of any Securities for a period of 15 days before a selection of
Securities to be redeemed.

         11. PERSONS DEEMED OWNERS. The registered Holder of a Security may be
treated as its owner for all purposes. Owners of beneficial interests in a
Global Security, as such, are not registered Holders under the Indenture and
will not be entitled to the rights of registered Holders hereunder or under the
Indenture.

         12. AMENDMENTS AND WAIVERS. Subject to certain exceptions, the
Indenture or the Securities may be amended with the consent of the Holders of a
least a majority in principal amount of the then outstanding Securities and any
existing default may be waived with the consent of the Holders of a majority in
principal amount of the then outstanding Securities. Without the consent of any
Securityholder, the Indenture or the Securities may be amended: to cure any
ambiguity, defect or inconsistency; to provide for assumption of the Company's
obligations to Securityholders; to make any change that does not adversely
affect the rights of any Securityholder; to provide for uncertificated
Securities in addition to certificated Securities; to surrender a right or power
conferred by the Indenture upon the Company; or to modify the Indenture to
effect its qualification under the Trust Indenture Act.

<PAGE>   92
         13. DEFAULTS AND REMEDIES. An Event of Default is: default for 30 days
in payment of interest on the Securities; default in payment of principal of the
Securities; failure by the Company for 60 days (10 days with respect to failure
to comply with the Change of Control covenant) after notice to it to comply with
any of its other agreements in the Indenture or the Securities (except that with
respect to certain other covenants, such defaults shall be Events of Default
with such notice but without such passage of time); certain defaults under and
acceleration prior to maturity of certain indebtedness; certain final judgments
which remain undischarged; and certain events of bankruptcy or insolvency. If an
Event of Default occurs and is continuing, the Trustee or the Holders of at
least 25% in principal amount of the then outstanding Securities may declare all
the Securities to be due and payable immediately, except that in the case of an
Event of Default arising from certain events of bankruptcy or insolvency, all
outstanding Securities become due and payable without further action or notice.
Securityholders may not enforce the Indenture or the Securities except as
provided in the Indenture. The Trustee may require indemnity satisfactory to it
before it enforces the Indenture or the Securities. Subject to certain
limitations, Holders of a majority in principal amount of the then outstanding
Securities may direct the Trustee in its exercise of any trust or power. The
Trustee may withhold from Securityholders notice of any continuing default
(except a default in payment of principal or interest) if it determines that
withholding notice is in their interests. The Company must furnish quarterly
compliance certificates to the Trustee.

         14. TRUSTEE DEALINGS WITH THE COMPANY. The Trustee or any of its
Affiliates, in their individual or any other capacities, may make or continue
loans to or guaranteed by, 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.

         15. NO RECOURSE AGAINST OTHERS. No director, officer, employee or
stockholder, as such, of the Company shall 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 and each beneficial owner of an interest in a
Global Security by accepting a Security or such beneficial interest, as the case
may be, waives and releases all such liability. The waiver and release are part
of the consideration for the Securities and beneficial interests, as the case
may be.

         16. AUTHENTICATION. This Security shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent.
